    Description
    Name of production: Combination weight
    Technical field
    The present invention relates to a combination weight which transports a metered workpiece to a gutter by turning a screw element located in the gutter.
    Background
    Patent literature 1 describes a combination weight. The combination weight supports a helical coil element 11 in a state where it is raised slightly from a bottom surface of a trough 10 which has a downward inclination towards one direction of a pool container 404. As a result, the coil element 11 does not contact the bottom surface of the trough. 10. Therefore, although the spiral member 11 is rotatably driven to transport the measured item, it is possible to avoid scratching the side of the bottom surface of the gutter 10.

    Patent Literature 1: JP 2009-270986 A
    Summary of the Production Technical Problem In the combination weights described in patent literature 1, the spiral element 11 and the gutter 10 do not come into contact with each other. Therefore, e.g. a metered blank, such as a raw liver, which varies in size of the products themselves and has high fluidity, from the gutter 10 toward the pool container 404 and fed to the pool container 404 as is. By dropping the metered workpiece itself into the gutter 10 due to its own weight, the conveying force transmitted from the spiral element 11, or the retaining power, to prevent this slippage in short is weakened and the metered workpiece having high fluidity slides on the gutter 10 and fed to the pool container 404.
    As the measured item slides into the gutter 10 and is fed to the pool container 404 as described above, it is difficult to control the rotation drive of the coil element 11 and to control the amount of feed to be supplied to the pool container 404. That is, it is difficult to controlling the supply amount of the final pool container 404, since it is not possible to control the supply amount of the measured item sliding down the gutter 10 of the actual product to the pool container 404, although the rotation drive of the coil element 11 is controlled.
    Thus, in the present disclosure, the amount of feed of the metered article to the container can be appropriately controlled, although a metered article having high fluidity, such as a raw liver, is transported from a gutter by means of screw feed mechanism. possible to a certain extent prevent the measured item from falling from the gutter to the container. The solution to the problem [0007]
    A combination weight of the present disclosure comprises a main body; A container; a gutter extending from the main body with a downward slope in the direction of the container; a screw unit disposed in the gutter and comprising a spiral member adapted to transport the measured member in the gutter to the container by rotation in the gutter; and a retaining member adapted to prevent at least a portion of the measured item from falling from the front end of the gutter to the container. The retaining member is disposed near the front end of the gutter; and a predetermined space is formed between the retaining member and the front end of the gutter.
    Advantageous effects of the production [0008]
    Since the combination weight of the present disclosure can prevent the metered item from falling from the gutter to the container, e.g. although a high fluidity metered article is conveyed from the gutter by a screw mechanism, the amount of metered article supply to the container can be appropriately controlled.

For example, may be cases where detailed descriptions of well-known conditions or repeated descriptions of substantially the same embodiment are omitted. This is to avoid unnecessary redundancy of the following description and to facilitate understanding of the person skilled in the art.
    [0011]
    It should be noted that the inventors of the present invention provide the accompanying drawings and the following description to enable those skilled in the art to adequately understand the present disclosure intended to limit the subject matter of the claims.
    (Embodiment)
    Next, the present embodiment is described with reference to FIG. 1 to 9.
    (1-1; General Operations Overview)
    Next, a combination weight 1 according to the present embodiment is described with reference to the drawings.
    [0014]
    FIG. 1 is a schematic perspective view of the combination weight 1 of the present embodiment.
    [0015]
    The combination weight 1 illustrated in FIG. 1, a distribution table 10, a transport unit 20, a screw unit 30, a retaining element 311, a pool container 40, a measuring container 50, a booster container 60, a collection discharge sludge 70 and a guide block 80 comprise.
    [0016]
    To make the description easier, only some parts of the plurality of screw assembly 30 and the plurality of retaining elements 311 are shown throughout the device of FIG. 1. During actual use, respectively. the screw unit 30 and the retaining element 311 disposed between the adjacent guide blocks 80.
    [0017]
    Next, the operating weight of the combination weight 1 is first described.
    First, the measured item is transported up to the combination weight 1 by means of a transverse feed device (not shown) disposed above the combination weight 1. Here, the measured item is a soft and sticky high fluidity food such as raw liver. However, the measured workpiece is not limited thereto and any food can be used as long as the food is hard to carry by ordinary vibrational transport and has high fluidity.
    [0019]
    The metered workpiece conveyed by the transverse feed device is fed to the substantially central portion of the distribution table 10. The distribution table 10 is rotated about an axis of rotation C (see Figure 1) extending in an upward direction. Then, the distribution table 10 transports the metered workpiece fed from above to the outside in the radial direction, while the metered workpiece is distributed in the circumferential direction. The measured item distributed and transported by the distribution table 10 is deduced from the outer peripheral edge of the distribution table 10.
    [0020]
    The measured item discharged from the distribution table 10 is fed to a plurality of transport units 20 arranged in an annular shape below the distribution table 10. The plurality of transport units 20 extend radially from the center of the distribution table 10. In other words, the plurality of transport units 20 radially from the center of the combination weight 1. Here, a guide block 80 is disposed between the adjacent transport units 20. By means of the guide block 80, the measured workpiece is prevented from falling between the transport units 20. Each transport unit 20 carries the measured workpiece supplied from the distribution table. 10, for the pool containers 40 disposed about the distribution table 10 one by one corresponding to each transport unit 20. In each transport unit 20, as the screw unit 30 arranged in the gutter 21 is rotatably driven, the measured workpiece is specifically transported within the gutter 21. Each transport unit 20 delivers the transported measured item to a pool container r 40 located below the outer end portion of the transport unit 20 (below the outer end portion of the gutter 21), thereby feeding the metered blank to the pool container 40.
    Here, when a workpiece to be transported is a high fluidity metered workpiece, the conveying force transmitted from screw unit 30 is weakened and it is assumed that the workpiece is dropped from the screw unit 30 to the gutter 21. which falls into the gutter 21, slides on the gutter 21 to the pool container 40 due to its own weight. The metered blank is then fed from the gutter 21 to the pool container 40 regardless of the propulsion of the screw unit 30. In the present embodiment, the retaining member 311 is disposed near the front end of the gutter 21 and a predetermined space S is formed between the retaining member 311 and the the front end of the gutter, among all the forward ends of the gutter 21, through which the measured item sliding into the gutter 21 passes as it descends to the pool container 40. By means of the retaining element 311 arranged in this way it is prevented. that at least a portion of the measured item sliding down in the gutter 21 falls as a result of the retention element 311. Therefore, it is easier to control the supply quantity compared to a situation where all the measured items sliding down the gutter 21 are fed. In short, it is possible to prevent the supply of a large amount of the measured item to the pool container 40 from the gutter 21 at a time.
    [0022]
    Pool container 40 temporarily holds the metered item supplied from the transport unit 20. Subsequently, the metered item which is held is passed to corresponding measuring containers 50 which are placed one after the other under the respective pool containers 40. In each measuring container 50, the weight of the metered item is measured. using a measuring mechanism (not shown). The measured item discharged from the measuring container 50 is stored in corresponding booster containers 60, which are placed one after the other under each measuring container 50 and held temporarily.
    [0023]
    A combination unit 1 (not shown) of the combination weight 1 achieves the combination of containers corresponding to or closest to a target weight among the combinations of weights in a permissible range, by calculating on the basis of the weight of the measured item in the measuring container 50 and the booster container 60. The measured item in the container contained in the combination obtained by calculating the control unit is delivered to the collection discharge slice 70. The measured item delivered to a collection discharge slice 70 is fed to a downstream process (not shown).
    (1-2; Description of each component element of the combination weight 1)
    Next, the distribution table 10, the transport unit 20, the pool container 40, the measuring container 50 and the booster container 60 are described in the combination weights 1 with reference to the drawings.
    [0025]
    FIG. 2 is a schematic perspective view of the distribution table of the combination weight 1 of FIG. 1. FIG. 2 shows at least one condition in which the guide block and the transport unit 20 are released.
    [0026]
    FIG. 3 is a partial cross-sectional view of the distribution table 10 of the combination weight of FIG. 1 and the transport unit 20 of the combination weight 1 viewed from the side. In FIG. 3, the front of a recessed groove portion of the gutter 21 of the transport unit 20 is not shown. The holder of the screw unit 30 of the transport unit 20 is shown in a cross-sectional view.
    [0027]
    The distribution table 10 is an element distributing the metered item supplied from a transverse feed device (not shown) disposed above the combination weight 1. The distribution table 10 further feeds the distributed metered item to the transport unit 20.
    [0028]
    Furthermore, the distribution table 10 is an element having a substantially circular shape in a plane view. The distribution table 10 has a tapered portion 11 disposed at the central portion and a peripheral portion 12 disposed at the peripheral edge of the tapered portion 11 (see Fig. 2). Both the tapered portion 11 and the peripheral portion 12 incline so that the peripheral edge side of the distribution table 10 becomes lower (see Fig. 3). The slope of the conical part 11 is designed to be steeper than the slope of the peripheral part (see Fig. 3).
    [0029]
    The distribution table 10 is supported by a drive shaft (not shown) arranged below the distribution table 10. The drive shaft supporting the distribution table 10 is connected to a distribution table motor (not shown). As the distribution table motor is operated, the distribution table 10 is rotated about the axis of rotation C extending in the vertical direction. In this case, the distribution table 10 may be arranged to rotate in a single direction or may be arranged such that the direction of rotation changes with the passage of time.
    When the metered workpiece is fed from a transverse feed device (not shown) positioned above the combination weight 1 to near the central portion of the distribution table 10 rotatably driven by the distribution table motor, the distribution table 10 transports the metered workpiece radially outwardly the supplied metered article is distributed in a circumferential direction by a centrifugal force. The measured item distributed and transported by the distribution table 10 is delivered from the outer peripheral edge of the distribution table 10 and falls into the gutter 21 (see Fig. 2) by one of the transport units 20.
    [0031]
    The transport unit 20 is an element that carries the measured item supplied from the distribution table 10. The combination weight 1 in the present embodiment has the fourteen transport units 20. However, the number of transport units 20 is an example and the present production is not limited thereto. The number of transport units 20 can e.g. be eighteen or twenty.
    [0032]
    The plurality of transport units 20 are positioned below the distribution table 10 to surround the distribution table 10 (see Figure 1). The plurality of transport units 20 are arranged to extend from the periphery of the distribution table 10 in a plan view towards the pool container 40 disposed about the distribution table 10. More specifically, the plurality of transport units 20 may be arranged to extend radially from the space below the distribution table 10 (see Figure 3) towards the pool container 40 disposed around the distribution table 10. Below each pool container 40, each measuring container 50 corresponding to the pool container 40 is provided (see Figure 1). That is, the transport unit 20 also extends radially from the periphery of the distribution table 10 to the measuring container 50 disposed around the distribution table 10. The transport unit 20 transports the measured item distributed by the distribution table 10 to the pool container 40 (in the transport direction MD shown in FIG. 3).
    [0033]
    Each transport unit 20 has essentially a gutter 21 and a screw unit 30. The screw unit 30 is disposed within the gutter 21.
    [0034]
    The gutter 21 extends from the space below the distribution table 10 toward the pool container 40 corresponding to the gutter 21 (see Fig. 3). Each trough 21 extends in the radial direction relative to the center of the distribution table 10 in a plan view. Each of the troughs 21 of the plurality of transport units 20 extends radially from the distribution table 10 as a whole.
    [0035]
    The gutter 21 additionally has a downward slope in the direction of the pool container 40 from the center of the distribution table 10. However, it is possible to prevent the measured item from hanging there, even though a high fluidity meter such as raw liver falls into the gutter 21. That is, the metered item falling into the gutter 21 slides into the gutter 21 due to its own weight and is fed to the pool container 40.
    [0036]
    Each trough 21 is separated from the interior space of frame 90 by an upstream side wall portion 91 (see Fig. 3). The frame 90 is positioned below the distribution table 10 to support the distribution table 10. An opening portion 1001 into which the screw unit 30 is inserted is further provided in the frame 90, and at least one lateral rotary drive unit 1002 which transmits the driving force to the screw unit 30 is stored. in the interior space of the opening portion 1001 (see Fig. 3). The rotation drive unit 1002 is connected to a motor M provided in the main body of the device and rotates about the axis of rotation D shown in FIG. 3 in connection with the operation of the engine M.
    [0037]
    Each trough 21 has a recessed groove portion 22 extending from the upstream side wall portion 91 and has an inner surface 22a that curves in a semi-circular shape (see Fig. 2). The recessed groove portion 22 is formed in a groove shape recessed downwardly by an inner surface 22a which curves in a semi-circular shape. In a plan view, the recessed groove portions 22 of each groove 21 extend from the upstream side wall portion 91 to the pool container 40 in a radially outward direction relative to the center of the distribution table 10. The recessed groove portion 22 inclines so that its outer edge side becomes lower, in other words. the side of the pool container 40 becomes lower than the side of the distribution table 10 (see Fig. 3).
    [0038]
    The measured workpiece delivered from the outer peripheral edge of the distribution table 10 is fed to the gutter 21. Since a triangular prism-shaped guide block 80 (see Fig. 1) is disposed between the neighboring grooves 21, the measured workpiece is fed to one of the gutters 21, without falling into the space between the neighboring rows 21 from the distribution table 10.
    [0039]
    The metered workpiece supplied to the gutter 21 is conveyed by rotation of the screw unit 30 disposed in the gutter 21. More specifically, the screw unit 30 transports the metered workpiece to the pool container 40 by rotating the screw member 31 located in the gutter 21.
    [0040]
    Each screw unit 30 is arranged for each gutter 21. The measured item falling into the gutter 21 is conveyed in the gutter 21 by rotation of the screw unit 30. The design of the screw unit 30 is described later.
    In the present embodiment, it is preferred that the screw unit 30 does not contact the gutter 21. With such a design, it is possible to prevent the surface of the gutter 21 from being scratched by the screw unit 30 as the screw unit 30 is rotated.
    [0042]
    However, a space is formed between the screw unit 30 and the gutter 21 when the screw unit 30 does not contact the gutter 21 as described above. When the metered workpiece is placed in this compartment, the conveying force transmitted from the screw unit 30, or the restraining power to prevent this slipping, is weakened, the metered workpiece slides into the gutter 21 because of its own weight.
    [0043]
    Each pool container 40 is provided below the outer edge side of each channel 21. Pool container 40 stores the metered item conveyed by the transport unit 20 and temporarily retains the metered item. Pool container 40 feeds the metered workpiece held temporarily to measurement container 50 provided under pool container 40 by opening an opening and closing port (not shown) provided at the bottom of pool container 40.
    The measuring container 50 is an example of a measuring means. The measuring container 50 is arranged around the distribution table 10. Each measuring container 50 is specifically provided under each pool container 40. In other words, each measuring container 50 is provided under the outer edge of the gutter 21 of each transport unit 20. The measuring container 50 stores the measured item supplied from the pool container. 40, and temporarily maintains the measured item. In addition, the measuring container 50 opens an opening and closing port (not shown) provided at the bottom of the measuring container 50 to supply the metered item temporarily retained to the booster container 60 provided under the measuring container 50.
    [0045]
    Each measuring container 50 has a measuring instrument (not shown) which measures the weight of the measured item in the measuring container 50. The measurement result of the weight is transferred to a control unit (not shown) of the combination weight 1.
    [0046]
    Each booster container 60 is provided under each measuring container 50. The booster container 60 is adapted to store and temporarily retain the measured item supplied from the measurement container 50. The booster container 60 opens the opening and closing port (not shown) provided in the lower portion. of the booster container 60 to supply the metered item which is temporarily held to the collection discharge slit 70 provided under the booster container 60. When the booster container 60 receives the supply of the metered item from the measuring container 50, whose opening and closing port (not shown) there. is provided in the lower portion of the booster container 60, is opened, it is possible to supply the metered blank to the collection discharge slit 70 without the metered blank being retained by the booster container 60 at any point.
    (2; Specific Design of Screw Unit 30)
    Next, the design of the screw unit 30 is described with reference to the drawings.
    [0048]
    FIG. 4 is a schematic view showing the structure of the screw unit 30 in the present embodiment.
    [0049]
    FIG. 4 is a view illustrating an outside diameter member 32 which is intersected at a predetermined plane and is shown such that a relationship between a grooved comb 330 provided on an inside diameter member 33 and outside The diameter element 32 disposed about the grooved comb can be understood.
    [0050]
    FIG. 5 is also a view illustrating the frame 90 to which the screw unit 30 is attached and an opening portion 1001, the rotation drive unit 1002 and the protruding portion 1003 provided in the frame 90.
    [0051]
    As shown in FIG. 4 and 5, the screw unit 30 is mounted in the opening portion 1001 formed in the frame 90 by a user.
    [0052]
    FIG. 6 is a schematic view illustrating any screw unit 30 seen from the outer periphery of the distribution table in the middle direction of the distribution table.
    [0053]
    As shown in FIG. 1, 3 and 6 at least one screw member 31 and a retaining member 311.
    [0054]
    The screw element 31 is as shown in FIG. 3 shows an Archimedean screw comprising a rotary shaft member 31a and a helical fin-like member 31b disposed on the outer periphery of the rotary shaft member 31a. Furthermore, the screw element 31 is not limited to the Archimedean screw. In short, any design can be used as long as the screw member 31 carries a metered workpiece of high fluidity.
    [0055]
    Here, the rotary shaft member 31a is an axis centered in the center of rotation of the screw member 31 and rotates together with the rotation of the motor M. The fin-like member 31b is furthermore a fin-shaped member. Even a metered workpiece having high fluidity can be conveniently transported, since the transport force is transmitted by a planar formed on the fin-like element 31b.
    [0056]
    In addition, a retaining member 311 is attached to the front end of the screw member 31.
    The retaining member 311 is secured to the front end of the rotary shaft member 31a. As shown in FIG. 3, a predetermined space S is formed between the front end of the gutter 21 and the retaining element 311. By providing the predetermined space S in this way, it is possible to avoid excessive supply of the measured item sliding into the gutter 21, to the pool container 40 and to shorten the time during which the measured item becomes suspended in the gutter 21. It is preferred that the predetermined space S is designed so that it can be changed by the metered item to be transported. For example, the predetermined space S is changed. depending on the size of the measured item to be transported. When the size per each measured item relating to transport is a first size, the predetermined space S relating to the first size is specifically set to be larger than the predetermined space S which relates to the measured item by a second one. size smaller than the first size.
    [0057]
    The predetermined space S may be set to have an average size per each measured item or a size of one or more metered items or less than two metered items. In this case, it is easy to control the supply amount, even though the measured item slides down from the gutter 21 to the pool container 40, since a large amount of measured item does not fall to the pool container 40 at a time.
    [0058]
    Here, the retaining member 311 is a lid-like member having a predetermined space through which approximately a metered blank e.g. can pass relative to the front end of the gutter 21 as described above and preferably has a configuration which cannot be opened and closed in the direction of transport MD of the metered workpiece. When the retaining element 311 can be closed and opened freely, the metered workpiece sliding down in the gutter 21 is fed to the pool container 40 without being retained by the retaining element 311.
    Furthermore, in a case where the retaining element 311 can be opened and closed, it is further preferred that the retaining element 311 is arranged to open only up to the predetermined space S. With such a design, even when the retaining element 311 is opened or closed, since If the retaining element 311 does not open beyond the predetermined space S, it is possible to prevent a large amount of the measured item from being supplied to the pool container 40 at a time. That is, in the above description, the gate mechanism which can be opened and closed in the direction of the pool container 40 from the distribution table 10 is secured to the front end of the gutter 21, which gate mechanism has a configuration which can open up to a predetermined space S , through which about a metered item e.g. can pass without being freely opened and closed. Even when, therefore, e.g. If a gate mechanism is provided to control the presence or absence of the measured item at the front end of the gutter 21, the gate mechanism and retention element may be used simultaneously and the number of components may be reduced. Therefore, the usability of the user can be improved as the number of components to be maintained or cleaned is reduced.
    [0060]
    Furthermore, the retaining element 311 is usually disposed without forming a predetermined space S on the gutter 21, and the retaining element 311 may be arranged such that a predetermined space S is formed between the retaining element 311 and the front end of the gutter 21 with the weight of the measured item. when the metered piece slides into the front end of the trough 21. With such a design, since it is possible to provide a configuration where the metered workpiece is not always supplied from the front end of the trough 21 to the pool container 40, it is possible to easily controlling the amount of feed of the measured item throughout the device.
    In the aforementioned case, it is preferred that a predetermined space S is arranged to be formed between the retaining element 311 and the front end of the gutter 21 when a plurality of e.g. three measured items reach the front end of the gutter 21.
    [0062]
    In addition, the screw element 31 is connected to the inner diameter element 33 and the screw element 31 also rotates in connection with the rotation of the inner diameter element 33.
    In a state where the screw member 31 is secured, the protruding portion 1003 formed in the rotary drive unit 1002 is specifically engaged with the grooved cam 330 formed in the inner diameter member 33. That is, that as the rotary drive unit 1002 rotates, the inside diameter element 33 rotates in the same direction as the rotation of the rotary drive unit 1002. Furthermore, as the inner diameter element 33 rotates, the screw element 31 connected to the inner diameter element 33 rotates. The measured workpiece is transported within the gutter and fed to the pool container 40 as the screw member 31 rotates.
    [0064]
    The outside diameter member 32 is a cylindrical member connected to the screw member 31. Since the inside diameter member 33 is disposed within the outside diameter member 32, the outside diameter member 32 also has a donut shape in cross section. The outer diameter element 32 is further arranged around the inner diameter element 33 via bearings and is adapted to have little influence on the rotational process of the inner diameter element 33. That is, even when the inner diameter element 33 rotates. , the outer diameter member 32 is arranged not to rotate upon receiving the rotational force thereof.
    [0065]
    The inner diameter element 33 is a cylindrical element connected to the screw element 31. Since the rotary drive unit 1002 and the protruding part 1003 formed in the rotary drive unit are additionally inserted into the inner diameter element 33, the cross section thereof has a donut shape. The inner-diameter element 33 is arranged in a space formed within the outer-diameter element 32. The inner-diameter element 33 is further mounted on the projecting part 1003 and has a grooved cam 330 on which the projecting part 1003 slips from the mounted state. This grooved comb 330 is a grooved comb 330 in which a groove is formed in a helical shape. Specifically, starting from a portion of the inner diameter member 33 mounted on the protruding portion 1003, the grooved cam 330 has a groove formed in a helical shape from the starting point. As the protruding part 1003 moves as it slides relative to the grooved cam 330, the inner diameter element 33 is introduced into the main body.

    To make the description easier when the screw unit 30 is attached to the main body, a portion initially mounted on the protruding portion 1003 is referred to as a first grooved cam portion 331. A portion in which the protruding portion 1003 moves as it slides from that state. in which the projecting portion 1003 is mounted on the first grooved cam portion 331 is further referred to as a second grooved cam portion 332.
    [0067]
    The first grooved cam part 331 and the second grooved cam part 332 are designed to be physically continuous with each other. That is, after the protruding member 1003 slides and moves on the first grooved cam member 331, the second grooved cam member 332 can continuously slide and move on the second grooved cam member 332 as it is. However, to move the projecting portion 1003 from the first grooved cam portion 331 to the second grooved cam portion 332 or from the second grooved cam portion 332 to the first grooved cam portion 331, it is necessary for a user to change the direction of the force applied to the screw unit 30 .
    [0068]
    More specifically, the coupling member 333 between the first grooved cam member 331 and the second grooved cam member 332 is preferably discontinuous in the direction in which the protruding member 1003 slides and moves. Specifically, the first grooved cam member 331 has a configuration in which the grooved cam member 330 is formed in the same direction as the axis of rotation D. By contrast, the second grooved cam part 332 is a grooved cam 330 formed in a helical shape with respect to the outer periphery of the inner diameter member 33.
    [0069]
    With such a design, the process when the protruding part 1003 is mounted in the first grooved cam part 331 and the process when the protruding part 1003 is moved while sliding on the first grooved cam part 331 and the second grooved cam part 332 can be made different from each other. . Furthermore, when the protruding portion 1003 is mounted in the first grooved cam portion 331, the user can apply a force in the same direction as the axis of rotation D. Therefore, even when it is difficult for him to see the fastening portion between the protruding portion 1003 and the first grooved cam portion, 331, intuitively mount the screw unit 30 on the protruding portion 1003.
    [0070]
    Furthermore, the designs of the first grooved cam part 331 and the second grooved cam part 332 are not limited to those described above, and any configuration can be used as long as the force applied to the screw unit 30 by the user is changed.
    [0071]
    As shown in FIG. 3 and 6, the retaining element 311 is an element having a plane orthogonal to the direction of transport MD, where the screw unit 30 carries the measured workpiece. Retaining member 311 is attached to the front end of screw assembly 30. As shown in FIG. 6, the retaining member 311 may be formed of a substantially circular plate-like member. In addition, the retaining element 311 may have a configuration different from a substantially circular configuration. In other words, any shape can be used as long as it is possible to prevent the metered object sliding down from the gutter 21 to the pool container 40 to a certain extent to fall down to the pool container 40.
    (3; Other Embodiments) In the above embodiment, the retaining member 311 has been described as a substantially circular plate member. However, the present invention is not limited to such a design, and the retaining element 311 may e.g. be designed to have an opening portion 311a in a portion of a substantially cylindrical shape.
    [0073]
    FIG. 7 is a view illustrating a configuration with an opening portion 311a in a portion of a retaining element 311 of the present embodiment.
    In FIG. 7, the retaining member 311 has an arcuate aperture portion 311a.
    When the retaining element 311 has the opening portion 311a as shown in FIG. 8, it is preferred that the retaining element 311 and the screw unit 30 be secured in such a way that a distal conveyor end (i.e., the front end of the screw unit) 31c of the screw unit 30 located immediately in front of the measured workpiece is inserted into the pool container 40 is located in the opening portion 311a of the retaining element 311. That is, because the screw unit 30 can adjust the supply amount of the measured workpiece to be fed from the end end to the pool container 40, it is easy to control the total supply quantity.
    [0076]
    As shown in Figure 9, the retaining member 311 has a first member 3111 and a second member 3112 disposed in a position that spatially overlaps the first member 3111, and the retaining member 311 may be designed such that the size of the opening member 311a can be changed by a change in a relative position relationship between the first element 3111 and the second element 3112. Since the supply amount from the screw unit 30 to the pool container 40 can be arbitrarily altered with such a design, the supply quantity can be controlled in more detail.
    [0077]
    In addition, the adjustment mechanism comprising the first element 3111 and the second element 3112 has been described in the above description. However, it is also possible to provide a configuration in which a shutter mechanism is provided in the retaining element 311, which side of the opening portion 311a is adjusted in accordance with the opening and closing rate of the shutter mechanism, and consequently the supply amount is controlled. In other words, any construction can be used as long as the opening member 311a is provided in the retaining member 311 and the size of the opening member 311a can be adjusted.
    When the retaining element 311 has the opening portion 311a as the screw unit 30 moves from the operating state to the state in which it stops, the control unit for controlling the motor M shown in FIG. 3 and 8 are also preferably a guide so that the opening portion 311a stops at a position different from the front end of the gutter, from which a specific metered blank falls. That is, in the case of a general configuration in which the gutter 21 is disposed on the lower side of the screw unit 30, the control unit performs a control such that the opening part 311a of the retaining element 311 becomes a vertical upper side. Therefore, it is possible to prevent the front end of the gutter from which the measured item slides into the gutter 21 and falls to the pool container 40, coincides with the opening part 311a to stop, and it is possible to prevent a large amount of measured items. in being fed to the pool container 40 while sliding down.
    [0079]
    In addition, the configuration in which the retaining element 311 is provided at the front end of the screw unit 30 is described in the above embodiment. However, the retaining member 311 may be disposed near the front end of the gutter 21, and a predetermined space S may be formed between the retaining member 311 and the front end of the gutter 21, from which at least one specific metered member falls, among all the forward ends of the gutter. 21. Therefore, it is not absolutely necessary for the retaining member 311 to be secured to the front end of the screw assembly 30. The retaining member 311 may e.g. may be attached to the gutter 21 or may be secured to the guide block 80.
    (4; Summary)
    The combination weight 1 of the present embodiment comprises a main body, a pool container 40, a trough 21 which extends as it descends in the direction towards the pool container 4O, from the main body, a screw unit 30, which is a coil element disposed within the trough. 21, for carrying the metered item in the gutter 21 to the pool container 40 and carrying the metered item by rotation of the gutter 21 inside, and a retaining element 311 which prevents at least the fall of the specific metered item falling into the pool container 40 in trench.
    The retaining element 311 is disposed near the front end of the gutter 21 and a predetermined space S is formed between the retaining element 311 and the front end of the gutter 21 among all the forward ends of the gutter 21, from which at least one specific metered object falls.
    [0081]
    As a result, although the transport force transmitted from the screw unit 30 is weakened and the measured object falling into the gutter 21 slides into the gutter 21, the retaining element 311 prevents the measured object from falling down to the pool container 40. Since in addition, the predetermined space S is formed between the front end of the gutter 21 and the retaining element 311, the measured workpiece sliding down in the gutter 21 may also fall to the pool container 40 without remaining in the gutter 21. Since it is possible to avoid a situation Therefore, where the metered piece slides into the gutter 21 and is fed to the pool container 40 in large quantities at a time, it is therefore easy to control the supply amount for the entire device with the rotary drive control of the screw unit 30.
    [0082]
    The retaining element 311 is also preferably an element having a plane orthogonal to the direction of transport MD, where the screw unit 30 carries the measured workpiece.
    [0083]
    Furthermore, since the retaining element 311 can prevent the metered item from sliding down the gutter 21 on a plane, it is possible to prevent the metered item from falling down to the pool container 40. Therefore, it is easy to control the supply amount for the entire device.
    [0084]
    The retaining element 311 is preferably attached to the front end of the screw unit 30 and has an opening portion 311a in a portion of the plane. The retaining element 311 and the screw unit 30 are secured such that the conveyor end portion 31c of the screw unit 30 located just in front of the measured workpiece is inserted into the pool container 40 located in the opening portion 311a of the retaining element 311.
    [0085]
    As a result, the metered piece conveyed to the front end of the screw unit 30 is fed to the pool container 40 as is, without falling into the gutter 21. That is, it is possible to control the feed amount of the metered piece by using the rotary drive of the screw unit 30. Therefore, it is easy to control the supply amount for the entire device.
    [0086]
    In addition, a control unit is preferably included for controlling the operation of the screw unit 30. When the screw unit 30 moves from the operating state to the state in which it stops, the control unit controls the screw unit 30 in such a way that the opening part 311a stops in a position different from the the front end of the gutter from which falls a specific metered item.
    [0087]
    Thus, it is possible to prevent the amount of the measured item from falling from the gutter 21 down to the pool container 40 due to its own weight, regardless of the stopping of the screw unit 30. This makes it easier to control the supply quantity for the whole device.
    [0088]
    Preferably, the screw unit 30 comprises at least one rotary shaft member 31a and a helical fin-like member 31b disposed in the outer periphery of the rotary shaft member 31a, and the retaining member 311 is secured to the front end of the rotary shaft member 31a.
    [0089]
    The retaining element 311 preferably has an adjustment mechanism which changes the size of the opening portion 311a.
    [0090]
    As a result, the user of the device can arbitrarily adjust the size based on the size of the measured item.
    [0091]
    In addition, retention element 311 preferably has the first element 3111 and the second element 3112 which spatially overlap the first element 3111. The size of the opening portion 311a is changed by a change in the relative position relationship between the first element 3111 and the second element 3112.
    [0092]
    The screw unit 30 and pool container 40 of the combination weight are as shown in FIG. 1 has been described such that they are arranged at least around the distribution table 10 in an annular configuration. However, this design is only one example of using the present invention. For example, For example, a combination weight is provided where the screw unit 30 and the pool container 40 are linearly disposed and the two linearly arranged elements are arranged in parallel. In short, any combination weight can be used where the screw unit 30 and the pool container 40 are arranged in a straight line.
