    Apparatus and method for the production of waffle blocks
    The invention relates to a device and a method for producing multi-layer waffle blocks filled with a coating material, such as a cream, in which a first waffle block component is transported along a conveying surface to a stacking area where it is lifted off the conveying surface by a gripping device, wherein subsequently or simultaneously a second waffle block component Waffle block component is transported along the conveying surface to the stacking area.
    Methods and apparatus for making multi-layer creme-filled waffle blocks have been known for a long time and have been published in various embodiments.
    For example, a method is known wherein cream-coated wafer sheets are transported in a first plane to a stacking location where they are raised to a second level and attached from below to the already raised portion of the wafer block, each coated wafer sheet being first under the raised position held portion of the waffle block is pushed and then lifted, and the thus formed wafer block is removed in the raised position from the stacking location.
    The prior art stacking and pressing devices for the production of wafer blocks usually have a along the conveying surface of the supplied wafer sheets arranged a stop on which the moving wafer sheets are stopped and supplied to other wafer sheets for the purpose of stacking. Modern waffle baking ovens and modern coating machines for creams and other coating compounds are designed to produce or coat high throughputs of 60 to 100 wafers per minute. The usual size of the wafer sheets is up to about 400 mm x 800 mm. To process such quantities in a short time, it is necessary to make the stacking of the individual coated or uncoated wafer sheets as efficient as possible without compromising the quality of the finished product.
    2 50 295 GP-GA
    A disadvantage of the prior art constructions is that the wafer sheets must be stopped in the stacking area, stacked and accelerated again. Due to the low resistance of Waffelblättem, especially crispy brittle flat waffles baked in Waffelbacköfen with closable baking tongs under high pressure and high temperature, the wafer sheets can not be arbitrarily accelerated or decelerated, otherwise there is structural damage in particular breaks, damage to the sheet edge and can lead to further damage. Such damaged wafer blocks, for example, with broken edge or cracks in the wafer sheets must be sorted out after the manufacturing process and eliminated as waste. A further disadvantage of the prior art production method and its devices is that the accuracy in the stacking process, in particular the exact congruent positioning of the wafer sheets one above the other is not sufficient. This results in the edge area to partial overlaps or even protruding individual wafer sheets. The edge must be subsequently processed or cut, which in turn brings a higher committee.
    Object of the following invention is therefore to provide a method and apparatus for producing multilayer waffle blocks filled with a coating material such as a cream, which allows a high throughput, in particular a variety of waffle blocks can produce in a short time and the high standards the quality is sufficient and, moreover, the waste minimized, easy and cheap to manufacture and efficient in maintenance and operation.
    The waffles are preferably flat waffles. For the production of wafers, for example, devices and methods are known in which wafer sheets, in particular crispy brittle flat wafers, which are baked in tongs baking machines, wherein the wafer sheets baked at high pressure in closed and locked waffle tongs and then cooled. The wafer sheets are preferably thin-walled, crispy brittle wafers with a size of up to 400 x 800 mm. These wafers are used, for example, in the formation of cut blocks which have a layered structure,
    3 50 295 GP-GA, for example, consist of alternating layers of wafer sheets and cream fillings. Cut blocks may for example consist of two Waffelblättem with an intermediate layer of cream, two Waffelblättem with several intervening cream layers, but also from a structure of more than 2 Waffelblattschichten, each between two Waffelblättem one or more cream layers are arranged. In most cases, the cut blocks each have a waffle sheet on two outer surfaces. The final layers are thus executed as wafer sheets.
    The object of the present invention is now to provide a method and an apparatus for producing multi-layered filled with a coating waffle blocks, wherein a high throughput is achieved, while the Waffelbtockbestandteile are positioned exactly above each other, the Waffelblockbestandteile be processed as gently as possible and wherein the device low in production and low in maintenance.
    The object of the invention is achieved in that the first waffle block component is placed on the second waffle block component from above in a joining operation and / or pressed.
    Further, the present invention is characterized in that the first waffle block component and the second waffle block component have the same speed in the conveying direction at each time of the joining operation, the non-zero speed being that of the first waffle block component of a gripping device in a forward conveying position lifted off the conveying surface and placed in a, in the conveying direction rear position on a subsequent Waffelblockbestendteil and that the first Waffelblockbestandteil and the second Waffelblockbestandteil jointly lifted by the gripping device in a, forward direction position of the conveying surface and to a rear in the conveying direction position on a subsequent Waffelblockbestendteil be placed. The method is advantageously characterized in that the waffle block components are transported by a first transport device into the stack area, that the first waffle block component is formed from two congruent, parallel superimposed Waffelblättem, wherein between the waffle sheets at least one layer of a coating material such as a cream is provided and that the second Waffelblockbestandteil is formed from a wafer sheet, which has on a flat side, preferably on the, the gripper side facing a layer of a coating material such as a cream.
    On the apparatus according to the invention for producing multilayer waffle blocks filled with a coating compound such as a cream, with a first transport device for transporting the waffle block components along the conveying surface in the conveying direction and a gripping device for stacking the waffle block components, it is advantageous that the gripping device comprises a gripper which at least is arranged movable in sections along the conveying surface, that the gripper is movable at least along two translatory degrees of freedom, that at least one gripping arm for moving the gripper (5) is provided and that the gripping arms each have at least one drive.
    Further, it corresponds to the inventive idea that a counter-holder is provided, that the counter-holder along the conveying surface in and against the conveying direction is displaceably arranged and that the gripper is arranged to be displaceable substantially normal to the counter-holder.
    It should also be noted in a positive manner that the gripper is arranged translationally displaceable substantially parallel to the anvil and that the gripper is designed as a vacuum plate and having openings which are at least partially closed by a first Waffelblockbestandteil.
    In the following the invention will be described in more detail with reference to some embodiments:
    1 shows a device according to the invention in a schematic sectional representation with a first transport device 1 on which the wafer block components are transported along the conveying surface 30 in the direction of the stacking region 8. In the stacking area 8, a movable gripping device 4 is arranged, which takes over essential parts of the method such as stacking, pressing, lifting, lowering etc. The gripping device 4 comprises a gripper 5. This is designed in the present embodiment as a vacuum plate and has
    5 50 295 GP-GA its, the first transport device 1 side facing away, a vacuum line 9, a vacuum pump 10 and an air filter 31 to protect the vacuum pump 10 on. At the first transport device facing side, the gripper 5 openings or cavities, which can be at least partially closed by the sucked wafer sheet or the sucked first Waffelblockbestandteil 2. By closing the openings, a squeeze can be built up which holds the waffle sheet or waffle block component to the gripper 5 with a holding force.
    Furthermore, the gripping device 4 has a base body 28 which is connected to the gripper 5. The gripper arms, in particular the front gripper arm 6 and the rear gripper arm 7 are movably connected to the gripper 5 and / or to the main body 28. The name behind refers to the rear in the conveying direction 11 position.
    The gripper arms each have drives, wherein the front gripper arm has a front drive 12 and the rear gripper arm has a rear drive 13. These are driven by motors 32, 33 in the present embodiment. The front motor 32 drives the front drive 12 via a transmission and the rear motor 33 drives the rear drive 12 via another transmission. Furthermore, the gripping device has a plurality of guide elements, by which the kinematics and the degrees of freedom and their freedom of movement are determined. Furthermore, a counter holder 14 is provided in the stack area 8. This counter-holder is arranged in such a way that the waffle sheet or the waffle block component is located in the stacking area between the gripper 5 and the counter-holder 14. The counter-holder is arranged to counteract the force of the gripper 5, which is directed in different process sections in the direction of the first transport device 1.
    The entire device is arranged on a machine frame 15, which in turn can be fixed on devices, not shown here, on the rest of the machine or on the ground. * * c * • *
    6 50Z95 GP-GA
    In addition, at least one detector 16 is provided. The detector is connected to a control unit 17, not shown, and serves to determine the time of entry of Waffelblockbestandteils and to synchronize and control the movement of the gripping device 4 in particular the gripping arms 6, 7. Also the gripper, the gripping device, the vacuum pump, the first transport device and / or the drives of the transport arms etc. may be controlled by the control unit 17.
    The process of forming wafers is done in several steps:
    Waffle sheets are baked in a tongs oven and fed to a cooling device. This cooling device conveys the baked, crunchy brittle, thin, sheet-like wafer sheets to a transport device. Subsequently, wafer sheets are coated on one side with a coating, in particular a cream or several layers of a coating. The application of the coating is done in coating devices such as contact coaters, roller coater, film coater or by orders through nozzles or similar devices. The single-sided coated wafer sheets are stacked on top of each other to form a multi-layered structure. Usually there are wafer blocks with two, three, four, five and more layers of wafer sheets, wherein between the Waffelblättem one or more layers of a cream are provided. Most of the top and bottom layers of the waffle block are each formed from at least a portion of a waffle sheet.
    In order to form a waffle block, a first waffle block component 2 is conveyed by the first transport device 1 into the stack area 8. The first transport device 1 is designed as a belt conveyor and has a driven belt 18, which is returned via a deflection roller. Further possibilities for conveying the waffle block components are, for example, belt conveyors, roller conveyors, etc.
    The first waffle block component is preferably constructed in three layers and has two outer wafer sheets, which are filled with an intermediate cream filling. The first waffle block component 2 is now marked with a * »• * r 6
    7 50 295 GP-GA transported certain speed of the first transport device in the stack area. The movably arranged gripper 5 is moved in the conveying direction 11, at least just before the gripping process at the same speed in the conveying direction and placed from above on the first waffle block component 2. The gripper 5 is pressed by the gripping arms 6, 7 in a rear position on the first waffle block component 2 lying on the first transport device. By the first Waffelblockbestandteil the cavities of the gripper 5 are closed, which can form due to the vacuum pump 10 and the connected vacuum line 9 in the cavities a suppression. From the suppression results over the surface of the sucked Waffelblockbestandteils a holding force with which the first Waffelblockbestandteil is held on the plate-shaped gripper 5. It should be noted that moves during the process of placement and suction of the gripper with the first transport device and the first Waffelblockbestandteil 2 in the conveying direction 11.
    Fig. 2 shows a position of the device according to the invention in which the gripper 5 is placed on the first waffle block component and is moved from a rear position as shown in Fig. 2a to a forward position as shown in Fig. 2b. During the movement from the rear to the front position, the gripper, in addition to the movement in the conveying direction, can perform additional movements normal to the conveying direction, in particular in the direction of the first waffle block component 2 and on the direction of the band 18. In order to prevent a deflection of the belt 18 of the first transport device 1, a counter-holder 14 is provided below the gripper 5. This is slidably disposed along the conveying direction 11 and the conveying surface 30, but blocked against displacement in the vertical direction. If now the gripper is pressed onto the first waffle block component, then this force is subsequently transferred to the band 18, which in turn is supported on the counter holder 14. The anvil, like the gripper 5, is carried at the speed of the first waffle block component. In a preferred manner, therefore, no slip occurs between the components gripper 5, first waffle block component 2, band 18 and counterholder 14 in the stacking region 8. The entire composite moves along the conveying surface 30 now to the end of the stacking area 8 on. There, as shown in Fig. 2c, the gripper lifted from the belt 18 of the first transport device 1. Due to the holding force, the first • 4 • Φ *

    Waffle block component 2 also lifted off and removed from the belt 18. The movement of the gripper 5 is done by controlling the drives 12,13 of the gripping arms 6, 7. During this process, the speed of the gripper plate deviates substantially from the speed of the belt 18 in the conveying direction 11. Subsequently, the gripper 5 is further removed from the belt 18 and lifted in the vertical direction. This is shown in Fig. 2d.
    FIG. 2 e shows a further position in which a movement of the gripper 5 takes place against the conveying direction 11. The gripper 5 is moved by the front gripping arm 6 and the rear gripping arm 7 against the conveying direction 11 and is, as shown in Fig. 2f further fed back towards a rear position.
    After or during the return movement of the gripper, which is illustrated in FIGS. 2e-2f, a second waffle block component 3 is transported by the first transport device 1 in the direction of the stacking region 8. The first waffle block component 2 and the gripper 5 are lifted from the first transport device, whereby they can freely feed the second waffle block component 3 to the stack area.
    Fig. 2g shows a position near the rear dead center or the maximum freedom of movement of the gripper 5 in the left direction shown here - ie opposite to the conveying direction 11. In this case, the gripper 5 is located above the second waffle block component 3 and is moved parallel to this. The movement or the position of the gripper 5 over the second waffle block component 3 is synchronized via the control unit 17.
    The detector 16, which is designed for example as a light barrier, determines the synchronization and thus the exact placement of the first waffle block component 2 on the second waffle block component 3. For this purpose, the control unit engages in the movement of the drives 12, 13 of the gripping arms 6, 7. If the second waffle block component 3 is located in the stacking area 8, as shown in FIG. 2g, the gripper together with the adhering first waffle block component 2 is carried above the second waffle block component 3 at the same speed and subsequently placed on it as shown in FIG. The second Waffelblockbestandteil is preferably carried out in two layers and has on its lower side lying on the belt 18 a wafer sheet and on the, the gripper 5 side facing a layer of a cream or a coating on. This will be the first
    Waffle block component exactly congruent to the second Waffelblockbestandteil pressed, creating a waffle block is formed, which consists in the present case of three layers of wafer sheets with intermediate layers of cream filling.
    Again, the gripper is pressed in the direction of the belt 18. As an abutment for the pressure or the resulting force of the guided in the conveying direction 11 backstop 14 is provided. In this process, the gripper 5, the first waffle block component 2, the second waffle block component 3, the upper part of the belt 18 and the anvil 14 move at the same speed in the conveying direction 11. During the movement from a rear position to a front position can turn next the movement in the conveying direction also a movement normal to the conveying direction, in particular for pressing the first Waffelblockbestandteiles on the second Waffelblockbestandteil done.
    The placement and pressing process takes place as shown in FIGS. 2a and 2b.
    At the end of the stacking area 8, the composite of the first waffle block component 2 is now lifted off with the second waffle block component 3, which is connected to the first waffle block component by adhesion of the cream, which in turn adheres to the gripper by the holding force.
    Now the waffle block is lifted off the belt and, as seen in Figs. 2c to 2g, is returned to a rear position. In the meantime, a third waffle block component may be supplied and, as before, the second waffle block component may be connected to the waffle block components held on the gripper.
    In this case, the gripper 5 is moved along a controlled by the control unit 17, circular contour. The movement is shown in particular in FIGS. 2a to 2h, wherein for the stacking of several waffle components this circular movement can be repeated as often as desired. In the stacking of several, for example, three Waffelblockbestandteilen would follow the next step after the position shown in Fig. 2h position again similar to Fig. 2a. However, the gripper 5 is positioned higher by a certain amount in the vertical direction than in the first passage of the circular movement. This amount corresponds essentially to the height of the waffle block formed so far. The positions of Fig. 2a
    10 50 295 GP-GA to 2h thus follow each other in a continuously moving process, the order of the positions of the alphabetical order of Fig. 2a corresponds to 2h.
    For placing the existing, held on the gripper 5 wafer block on another, following Waffelblockbestandteil the gripper and the waffle block thereon is carried above the moving subsequent Waffelblockbestandteiles and placed in a, compared to the following Waffelblockbestandteil substantially vertical movement. Both parts, ie the gripper 5 and the waffle block component to be attached, move in the direction of the conveying direction 11 at the speed of the first transport device 1. In order to achieve the exact placement of the gripper 5 on the subsequent waffle block component, a detector 16 is provided. This detects the time of entry of the subsequent Waffelblockbestandteils. The movement of the gripper 5, in particular the gripping arms 6, 7 can now be synchronized by the control unit 17 via the speed of the first transport device. Subsequently, the gripper with the adhering, existing waffle block on the subsequent Waffelblockbestandteil and presses it in the stacking area against the belt 18 and subsequently against the anvil 14. By the plate-like configuration of the gripper 5 and the counter-holder 14 can by the pressure exerted Height of the waffle block can be changed in certain areas. In particular, in mass production, it is of great importance that the finished product corresponds to certain dimensional tolerances.
    For this purpose, the waffle blocks are stacked, and then compressed to a standard size. This pressing process, in which the plate-shaped gripper 5 is pressed against the anvil 14, takes place during a continuous movement along the conveying direction 11.
    In the stacking process, due to the thickness of the stacked waffle block components, the gripper lowers by a certain amount less in the direction of belt 18 at each pass. When the desired waffle block thickness or desired number of layers is reached, the gripper disengages from the waffle block. Subsequently, this is removed by the first transport device. »· · S * * 44 · 4«
    11 50 295 GP-GA
    Alternatively, however, after the first pass, i. after placing and pressing the first waffle block component onto the second waffle block component, the connection of the gripper 5 to the waffle block is released. Connecting the waffle block can be removed via the first transport device.
    Loosening is done by the fact that no negative pressure is applied to the gripper, whereby the holding force disappears and the waffle block is no longer held on the gripper. Preferably, this separation occurs when the waffle block is on the belt 18 of the first transport device 1.
    It should be noted that the entire batching process is continuous, i. the individual waffle block components do not have to be stopped on the belt, but are suspended from them during a uniform movement and connected together.
    Fig. 3 shows a schematic view of the device according to the invention, wherein the elements shown are shown partially in section. The viewing direction essentially follows the conveying direction 11 from FIG. 1.
    The device comprises a gripping device 4 with a gripper 5 and a counter-holder 14. The gripper 5 and the counter-holder 14 have kinematic constraints on each other. So the two plates are guided parallel to each other. Tilting one plate over the other is possible only in the area of a small clearance of the guide elements. This parallel guidance of the gripper 5 and the counter-holder 14 is carried out via bolts 19 and bushings 20. In this case, a plurality of sockets 20 is provided on the one element, in which bolts 19 out, slidably disposed, which are connected to the respective other element. In the present embodiment, four bolts 19 are fixedly connected to the gripper 5 and / or the main body 28 of the gripper. The bolts extend substantially vertically or normal to the conveying direction 11 and to the main extension direction of the plate-shaped gripper 5. The bolts 19 protrude into bushings 20, which are firmly connected to the counter-holder 14. The sockets have openings into which the bolts 19 can be inserted. The openings of the sockets are * * ...... «· · **» «· l >« * * 1
    12 50 295 GP-GA designed that only a linear movement of the bolt is possible. The direction of the linear movement substantially corresponds to a normal to the main extension direction of the plate-shaped gripper 5. Further, the components vacuum pump 10, air filter 31 and vacuum line 9 are provided for generating the holding force.
    The counter-holder 14 is designed plate-shaped in the present case and arranged linearly displaceable along the conveying direction. In particular, the counter-holder 14 is arranged displaceably in the stacking region 8. Kinematically, this means that the counter-holder 14 can only be moved linearly along the conveying direction. The guide is given by the arrangement of a linear guide element 29. The gripper 5 in turn can be moved relative to the anvil 14 exclusively parallel and linear. However, the direction of the translational movement of the gripper 5 relative to the anvil 14 is normal to the conveying direction - in the present case vertically - while the possible direction of movement and the direction of the translational degree of freedom of the backstop 14 follows the conveying direction thus in the present case is horizontal. By configuring this kinematics, the gripper 5 can thus be moved vertically as well as horizontally. The movement takes place via the front gripper arm 6 and the rear gripper arm 7 which engage on the one hand on the machine frame 15 and on the other hand on the gripper 5 and / or on the main body 28. It should be noted that each two front gripping arms and two rear gripping arms can be arranged - as shown for example in Fig. 4.
    The front gripper arm 6 comprises a front drive 12. This drive is designed as a rotary drive and has in its center an axis of rotation about which the first arm 21 is rotatably arranged. The front motor 32 drives the front drive via a gearbox. The first arm 21 has at its, the front drive 12 remote from the end of a rotary bearing 25, via which it is connected to the second arm 22. This rotary bearing is designed for example as a pin-socket connection. It allows a rotational movement of the second arm 22 relative to the first arm 21 about the axis of rotation of the rotary bearing 25. The second arm 22 is in turn connected at its end facing away from the first arm via a rotary bearing 25 with the gripper 5 and / or the main body 28. The + * * «* * * ··· * * *« »· a« * «· · * l *« ««... »» »» , • · a * * * * * ·.
    13 50 295 GP-GA
    Connection of the second arm 22 with the gripper 5 also allows the free rotation of the second arm 22 about the rotary bearing 25.
    The rear gripper arm is also formed and has a rear drive 13 driven by the rear motor 33, which can rotationally drive a third arm 23. This has on the, the rear drive 13 remote from the end turn a rotary bearing 25, via which it is connected to the fourth arm 24. The fourth arm is rotatably arranged on a rotary bearing 25 on the gripper 5 and / or the main body 28. Due to the controlled drive of the drives 12,13, the pitch of the gripper 5 relative to the machine frame 15 in the kinematic limits can be selected. The arrangement of the gripper arms corresponds in the broadest sense of the kinematic design of a connecting rod, wherein in addition to the vertical movement by the two drives and a horizontal movement can be obtained. Both drives are controlled by the control unit 17 (not shown). To improve clarity, the degrees of freedom are now specified in more detail below:
    The axes of rotation of the front drive 12 of the rear drive 13 and all rotary bearings 25 extend in Fig. 1 projecting. Likewise, the axis of rotation of the drive and the deflection roller of the first transport device is projecting. The first arm 21 and the second arm 22 have a rotational degree of freedom with respect to one another, wherein the rotational axis of the rotational degree of freedom corresponds to the rotational axis of the rotary bearing 25. Similarly, the third arm 23 and the fourth arm 24 are arranged rotatably to each other, wherein the axis of rotation corresponds to the axis of rotation of the rotary bearing 25. The fourth arm and the second arm engage the gripper 5. It should be noted that the arms 22 and 24 do not engage directly on the gripper 5, but on one, connected to the gripper 5 main body 28. The main body 28 may be rigidly connected to the gripper 5, wherein the gripper 5 also sprung or limited movable can be arranged the base body. The gripper 5 or the base body 28 is arranged parallel to the counter-holder 14. The main body 28 and the gripper 5 thus have a translational degree of freedom relative to the anvil 14. The counter-holder 14, in turn, has a translational degree of freedom which is substantially orthogonal to the degree of freedom of the gripper 5. The anvil is thus arranged translationally displaceable along the conveying direction 11 and runs just below the * * ♦ * * ft * ft ·· ** ··· * * «ft • * · · · · t τ · · ft ♦ ·· · · · · Ι '! ♦ * ♦ »·» I * I,
    14 50 295 GP-GA upper portion of the band 18. The anvil 14 is slidably disposed between the top of the band and the returning lower side of the band. It therefore runs directly below the section of the belt on which the waffle block components are conveyed. Preferably, the backstop 14 is located in the stacking area 8 directly below the waffle block component due to the control and movement of the drives 12, 13 and follows it along the conveying direction 11th
    Fig. 4 shows an oblique view of a device according to the invention with a first transport device 1, a first Waffelblockbestandteil 2, a gripping device 4 with a gripper 5, two front gripping arms 6 and two rear gripping arms 7 and a base body 28. The gripper 5 moves along a nearly closed circular contour, wherein in the lowered area a straight guide in the conveying direction, then a lift-off, a substantially rectilinear return movement and in the connection again a lowering movement.
    Furthermore, a vacuum line 9, a vacuum pump 10, a front drive 12, a rear drive 13 and the counter-holder 14 are provided. Rigid with the machine frame 15, a detector 15 is further arranged, which is connected to a control unit 17, not shown. The belt 18 of the first transport device 1 has a drive 26 and a deflection roller 27. Further, bolts 28 are provided on the main body 28, which are mounted in bushings 20 of the counter-holder 14.
    At this point it should be noted that the invention is not limited to the stated embodiments.
