    专利说明:

    The invention relates to a device for the intermediate storage of brush bodies, in particular toothbrush bodies, which is arranged between two brush body treatment devices and which is associated with a brush body. brush body delivery device in the region of an entry point and a brush body removal device in the region of a sampling point.
    Such devices are already known in many embodiments and are particularly used to decouple two successive manufacturing processes, for example the injection molding of the brush bodies in an injection molding machine and the insertion of tufts of hair in the brush bodies in an insertion device. In case of failure of one of the two treatment devices, the other can still continue to work. In case of failure of the injection molding machine, the insertion device can continue to be supplied with brush bodies manufactured beforehand from the intermediate storage device and in the event of failure of the insertion device, the brush produced in the injection molding device may nevertheless be brought into the intermediate storage device. In addition, the cycles of the two brush body treatment devices can be decoupled from each other.
    For example, intermediate storage devices are known in which brush bodies are placed in stacking magazines and are reciprocated between the brush body treatment devices. The problem with stacking magazines is that brush bodies with a rounded or rounded or curved gripping region are difficult to stack and therefore storage capacities are limited.
    DE 1 98 46 41 A1 discloses a brush-making machine which has an intermediate storage device with two revolution conveyor belts. The brush bodies are first placed by the first brush body treatment device on a first conveyor belt, are carried further by the latter, are transferred to the second conveyor belt and taken from there and fed to the first conveyor belt. at the second brush body treatment device. Since, in this case, the brush bodies are not stacked, this device is also suitable for brush bodies with complex gripping shapes. In this case, the storage capacity is however limited and more space is needed to achieve a higher storage capacity.
    Therefore, the problem is in particular to provide a device for the intermediate storage of brush body of the type mentioned at the beginning which offers a high storage capacity requiring little space and which also allows the intermediate storage of brush bodies having complex forms of grasping.
    The solution according to the invention to this problem is that the intermediate storage device has a housing for at least two deposits respectively for several brush bodies and can be positioned independently of one another, which deposits can be positioned between a feed position projecting beyond one side of the housing associated with a first brush body treating device and a picking position projecting beyond another side of the housing associated with a second brush body treatment device.
    Brush bodies can in this case be transferred from a first brush body treatment device, for example an injection molding machine, to another deposit disposed in the feed position, while another deposit is at the same time is in the sampling position and that brush bodies are taken therein and are fed to another brush body treatment device, for example an insertion device. Meanwhile, other deposits may be disposed in the storage position within the housing, allowing for a greater reserve of brush body.
    In this case, it is appropriate to provide several deposits arranged on top of each other which are placed in the manner of drawers in the housing and which can be positioned horizontally sliding between the supply position and the sampling position. . With such a housing designed as a drawer cabinet, it is possible to temporarily store a large number of brush bodies on a comparatively small area so that an optimized buffer capacity is achieved. In a housing having a base area of 1m x 1m and a height which is also 1m, it is possible to temporarily store, for example, some 250 brush bodies per deposit. With a deposition height of about 50 mm, it is possible to provide 20 deposits, so that a total of 5000 brush bodies can be buffered. With a processing speed of 50 brush bodies per minute in the brush body treatment devices, it would thus be possible to hold during one of the immobilization periods of one of the brush body treatment devices of about 100 minutes during which the other brush body treatment device can nevertheless continue to work.
    For an orderly deposit of the brush bodies in the deposits, it is advantageous for the deposits respectively to have a plurality of compartments for each receiving a brush body. The compartments may also have profiling on the support side to better deposit curved brush bodies.
    In injection molding machines, the brush bodies are generally manufactured in multi-cavity molds, comprising for example 8 cavities. In order to be able to rapidly collect the brush bodies thus injection molded and transfer them to the deposit of the intermediate storage device, it is appropriate that the brush body supply device and / or the brush body removal device respectively present a multiple clamp. Sampling in the sampling position can also be done with a multiple gripper to ensure rapid delivery of the brush bodies to the second brush body treatment device.
    For positioning in the depot in question at the right height and in the right position, the brush body supplying device and / or the brush body extracting device respectively suitably comprise a control device and a device. positioning for positioning in one of the depots.
    To prevent a brush body from being deposited in a position already filled with a deposit or a picking gripper performing a withdrawal movement in an unfilled position of a deposit, it is advantageous that a sensor unit intended to detect the filling state of a deposit and / or its compartments ready for filling or removal of the brush body, each time associated with the brush body supplying device and / or the body removal device brush.
    It is also possible to have a controller with a data memory for storing the fill level of individual depots and / or their compartments. When introducing a brush body, its position in the deposit in question is stored so that during the sampling, positions with brush bodies can be reached in a targeted manner. When a brush body is taken, this sample is also recorded so that it is noted in the data memory that there is no more brush body available in this position.
    A partition, a protective fence, or a similar separating element for spatially delimiting the entry point and the sampling point relative to one another may be associated with the intermediate brush body storage device. This makes it possible to spatially separate the two brush body treatment devices and makes it possible under safe conditions for maintenance work to be performed on one of the brush body treatment devices while the other brush body treatment device The brush continues to work, particularly when the feeding and sampling devices have robot arms in the working area from which more stringent safety measures are applied.
    With a partition between the point of entry and the point of sampling, it is possible, for example, to also place an insertion device in a clean room so that brushes can also be manufactured for medical purposes, for example for smear.
    In this case, it is appropriate to provide an adjustable closure valve between a closed position and an open position of the supply side and the collection side for deposits in the housing. As a result, the housing is always open in the region of a depot only in the direction of one side through which the deposit is taken out. On the opposite side, the housing is closed by a closing flap, which avoids a current of air between the two sides.
    It is further appropriate to provide intermediate floors in the housing between the individual deposits arranged one above the other. In this way the individual deposits are also isolated from each other and the hygienic conditions are further improved.
    A drive unit may be associated with each of the depots.
    However, it is also possible to provide a common training unit that can be associated with the choice or alternately with one of the depots.
    The drive unit (s) present (s) (respectively) a servomotor. This allows particularly precise control and positioning.
    The drive units may also have a pneumatic drive respectively.
    When the brush bodies are taken from the injection molding machine and brought to the intermediate storage device, they can cool in the storage position deposits inside the housing before being transferred in particular to a insertion device.
    The cooling of the brush bodies can be improved and accelerated when a cooling device is associated with the housing. In this case, the cooling device may in particular have a blower.
    An exemplary embodiment of the device for intermediate storage of brush bodies according to the invention will be described in more detail below on the basis of the drawings.
    It is shown schematically on:
    Fig. 1 a system with a device for intermediate storage of brush bodies and two brush body treatment devices,
    Fig. 2 a side view of a device for intermediate storage of brush bodies and FIG. 3 a view from above of the representation of FIG. 2.
    A device, designated in its entirety by 1, for intermediate storage of brush body 2 has, according to the figures, a housing 3 in which several deposits 4 for brush bodies 2, designed in the manner of drawers and arranged one above the others, are mounted horizontally sliding. The deposits 4 may be respectively moved between a projecting feed position above the housing 3, associated with an injection molding device 5, a storage position inside the housing 3 and a sampling position. protruding above the housing 3, associated with an insertion device 6 (Figure 1).
    As can be seen particularly well in FIG. 3, the deposits 4 respectively have several compartments 7 to each receive a brush body 2. Each deposit 4 has in the embodiment of the device 1, which is shown, 90 compartments 7. According to FIG. Figures 1 and 2, a total of 16 deposits are provided so that a buffer or total storage capacity of 1440 brush bodies 2 results. The need for space for the device 1 for intermediate storage of brush bodies 2 is however comparatively small despite the high storage capacity.
    FIG. 1 shows the operation of the intermediate storage device 1. Brush bodies 2 are manufactured in the injection molding device 5 and are transported by means of a brush body feed device 8 designed as a robot for injection molding. multiple axes to an entry point 9 where one of the deposits 4 is in its feed position and are deposited in a compartment 7 of the depot 4. For this purpose, a control device, not shown, with which the gripper 10 holding a brush body 2 can be positioned in the three coordinates of the space in the deposit 4 in question and in a free compartment 7 therein, is associated with the supply device 8 of the brush body. When all the compartments 7 of a deposit 4 are filled with brush bodies, the deposit is moved into its storage position inside the housing 3. Here, the brush bodies 2 can also cool, a cooling which can in addition contribute a cooling device not shown, for example a wind tunnel. While a deposit 4 is filled with brush bodies 2 in the region of the entry point 9, brush bodies 2 are taken from another deposit 4 disposed in the sampling position in the region of a point of contact. picking associated with the insertion device 6. The sampling device 12 of the brush body provided for this purpose can be moved with its clamp 10 in three dimensions to be positioned at a compartment 7 filled with the deposit 4 in question.
    Thanks to the intermediate storage device 1, the insertion device 6 can continue to work even when the injection molding device 5 has failed, in that brush bodies 2 previously introduced into the deposits 4 and temporarily stored in housing 3 are taken. Similarly, the injection molding device can continue to work in case of immobilization of the insertion device 6, in that the brush bodies 2 are transferred into empty deposits 4 and that they remain in a first time in the housing 3 and stored there temporarily. In addition, the cycles of the injection molding device 5 and the insertion device 6 are decoupled so that the two devices 5, 6 can work asynchronously.
    In the region of the housing 3 of the intermediate storage device 1, there is provided a partition 13 which separates the working areas of the injection molding device 5 and the insertion device 6 from one another. , maintenance or repair work may be performed on one of the devices (5, 6) under safe working conditions while the other device continues to work. It is also possible to design for example the working area of the insertion device 6 as a clean room so that brushes can also be manufactured for medical purposes.
    The intermediate storage device 1 can of course also be placed between other processing devices, for example between an insertion device and a grinding device or a packaging device.
