    The invention relates to a device for the intermediate storage of plate-shaped workpieces with a receiving magazine formed from stacked compartments for the plate-shaped workpieces, according to the preamble of claim
    1.
    In manufacturing facilities, particularly for the cutting, processing and assembly of plate-shaped workpieces, for example in the furniture industry, automation is increasing. The plate-shaped workpieces are transported between different production machines, where they are automatically cut and processed, and then fed to an assembly or packaging station. The problem arises that the processing time for the different workpieces sometimes varies, for example when different work steps have to be carried out. If the different workpieces have to be processed again at the same time in subsequent stages of production, for example in the course of assembly or packaging, the problem arises of intermediate storage of individual workpieces.
    In a conventional manner, workpieces are temporarily stored in batches. If necessary, a workpiece will be
    Bearing stack removed. If a specific workpiece has to be removed from the storage stack, it may be necessary to rework the stacked workpieces, which entails a considerable amount of time and work with the risk of damage to the workpieces. Automating the stacking and removal of individual workpieces is hardly possible in this way. This problem of intermediate storage arises particularly in the course of the trend towards individual one-offs and small series.
    It is therefore the object of the invention to provide a device for the intermediate storage of plate-shaped workpieces, which not only allows simple and gentle stacking of plate-shaped workpieces, but in particular also enables integration into automated production facilities.
    This goal is achieved by the features of claim 1. Claim 1 relates to a device for the intermediate storage of plate-shaped workpieces with a storage magazine formed from stacked compartments for the plate-shaped workpieces, in which it is proposed according to the invention that the storage compartments have storage surfaces, each in a first horizontal direction in a storage area and in a second The horizontal direction can be extended into a removal area and retracted into the receiving magazine, a receiving device with a pickup for the plate-shaped workpieces being arranged in the storage and removal area, which in the storage or removal area is in a plane parallel to the storage area and in a perpendicular to the storage area Direction is movable, and a control and storage unit for controlling the storage and removal movement of the transducer and the movement of the storage surfaces and for storing the storage location of plate-shaped workpieces au f the storage space is provided.
    The storage areas allow the plate-shaped workpieces to be stored horizontally. The workpieces are handled by sensors that pick up workpieces that are fed to the storage area, move them through the storage area and place them on an extended storage area. The relevant storage area is then retracted into the magazine. Subsequently, the storage surface can be extended into a removal area, where another customer picks up the workpiece and places it, for example, on a conveyor which feeds the workpiece in question to subsequent stations of the production facility. The control of the storage and removal movement of the pickup and the movement of the storage surfaces is carried out with the aid of a control and storage unit, which is preferably connected via an interface to the control of the other sections of the production facility / 15. In modern production facilities, the movement, location and processing status of individual workpieces that pass through the production facility are also tracked. The control and storage unit thus receives data records about individual workpieces that are fed to the storage area and thus also knows, for example, the dimensions of the workpiece in question. The control and storage unit also has data on the current storage locations of plate-shaped workpieces on the storage surfaces of the storage magazine. The control and storage unit can thus compare the dimensions of supplied workpieces with free storage areas and initiate an extension movement of a free storage area. The placement movement of the pickup is then controlled in such a way that the workpiece in question is deposited on the intended storage surface. The data on the available storage space is updated accordingly. As soon as the control and storage unit receives the request for the removal of a specific workpiece from subsequent sections of the production facility, the storage location of the workpiece is called up, the corresponding storage surface is extended into the removal area and the pickup in the removal area is controlled accordingly, so that the workpiece is moved in a removal movement extended storage area is lifted and placed, for example, on a conveyor.
    The storage area and the removal area are preferably arranged on opposite sides of the storage magazine, so that a simultaneous storage and removal of workpieces can take place and the storage and
    Removal speed can thus be increased.
    The sensor could be designed in different ways, but preferably the sensor is a vacuum sensor. In the case of a negative pressure sensor, a device similar to a suction cup is placed on the plate-shaped workpiece and a negative pressure is generated which / 15
    Press the workpiece against the transducer. The adhesive effect is reduced again by pressure equalization, so that the workpiece can be loosened and put down again.
    It is also preferably proposed that the storage surfaces are each provided with grooves arranged in a grid.
    When a plate-shaped workpiece is lifted, adhesion to the support surface caused by aerodynamic effects can occur, which makes lifting the workpiece more difficult and is prevented in a simple manner by the grid-like arrangement of the grooves.
    In the storage area, a receiving table can be provided, which is provided with at least two position sensors for the workpiece to be picked up. Although information about the type and properties of the workpiece fed to the storage area is usually available, the position of the workpiece can nevertheless vary, for example by being fed to the receiving table rotated about a vertical axis. It can therefore be advantageous if position sensors are provided which can be designed as simple distance sensors which are directed against an end edge of the plate-shaped workpiece in order to be able to detect a rotated position. The transducer can subsequently pivot the workpiece accordingly in order to enable a precisely fitting and space-saving storage on a storage surface.
    The receiving device can be designed such that it comprises a frame on which a carrier is mounted so as to be horizontally displaceable perpendicular to the longitudinal axis of the carrier, and on the carrier is mounted a carriage that can be moved in the longitudinal direction of the carrier, the receiver on the carriage in a vertical direction is kept movable. The movement of the carrier, together with the movement of the carriage, causes the sensor to move horizontally and to the
    Surface parallel plane. Together with the vertically movable mounting of the transducer on the carriage, movement of the transducer in all / 15
    Spatial directions are accomplished. This simple one
    Execution of the receiving device is possible due to the horizontal placement of the workpieces on the storage surfaces, so that when the workpieces are fed in a horizontal position, a positioning movement of the pickup is possible in which the workpiece can remain in a horizontal position without tilting movements or the like being necessary.
    The invention is based on a
    Embodiment explained with the help of the accompanying drawings. It shows the
    1 is a perspective view of an embodiment of the device according to the invention,
    2 the embodiment according to FIG. 1 seen from above, FIG. 3 a perspective view of an embodiment of the receiving magazine,
    Fig. 4 is a detailed view of the magazine and the
    Pickup when placing a workpiece on a
    Storage area of the recording magazine, and the
    5 is a further view of the embodiment according to FIG. 3 seen from above.
    First of all, reference is made to FIGS. 1 and 2, which show an embodiment of the device according to the invention with a receiving magazine 1, as well as a receiving device 2 arranged in a storage area and a removal area. The storage magazine 1 is formed from stacked compartments for the plate-shaped workpieces, the storage compartments having storage surfaces 7, each in a first horizontal direction in a storage area which is arranged to the left of the storage magazine 1 in relation to FIGS. 1 and 2, and in a second horizontal direction in a removal area which is arranged in relation to FIGS. 1 and 2 to the right of the receiving magazine 1, can be extended and can be retracted into the receiving magazine 1. In the embodiment shown in FIGS. 1-5, the storage area and the removal area are arranged on opposite sides of the receiving magazine 1. In the storage area / 15 there is also a receiving table 3 which is to be placed
    Workpieces W i are fed. 1, the workpiece W 1 is located on the receiving table 3.
    In the storage area and the removal area, a frame is arranged, on each of which a carrier 4 is mounted horizontally displaceably perpendicular to the longitudinal axis of the carrier 4 above the receiving magazine 1. A carriage 5 which is movable in the longitudinal direction of the carrier 4 is mounted on the respective carrier 4. On the carriage 5, in turn, a pickup 6 is held movably in a vertical direction. The movement of the carrier 4, together with the movement of the carriage 5, causes the sensor 6 to move in a horizontal plane. Together with the mounting of the transducer 6 on the carriage 5, which can be moved in the vertical direction, the transducer 6 can be moved in all spatial directions.
    The pickup 6 of the storage area is in particular able to perform a storage movement in which a workpiece Wi is picked up from the receiving table 3, moved over an extended storage surface 7 and is placed on the storage surface 7 provided. The pickup 6 of the removal area is in particular capable of performing a removal movement in which a workpiece Wi is lifted off an extended storage surface 7 and placed on a conveyor 8.
    The recording magazine 1 is explained with reference to FIG. 3. The receiving magazine 1 is formed from an essentially cuboid box, which has a plurality of storage surfaces 7 arranged one above the other in its interior, each of which is movably mounted in lateral guide rails. The lateral guide rails are arranged on opposite side surfaces 10a, 10b of the receiving magazine 1, these side surfaces 10a, 10b in the direction of the depositing and
    Removal area are extended. The storage surfaces 7 are driven with the aid of belt pulls, toothed belts, toothed racks or the like, and the motors assigned to the respective storage surfaces 7 are set in motion. The motors of the storage surfaces 7 are controlled by a control and storage unit 9/15 (see, for example, FIG. 1). FIG. 3 shows a storage surface 7 in an extended position, on which four workpieces W i are already deposited.
    The sensor 6 is shown in the
    Embodiment of a vacuum sensor, in which a suction cup-like device is placed on the plate-shaped workpiece Wi and a vacuum is generated that presses the workpiece W i to the sensor 6 (see for example Fig. 4). The adhesive effect is reduced again by pressure equalization, so that the workpiece Wi can be loosened and put down again. The control of the movement of the sensor 6 and the control of the negative pressure are also carried out with the aid of the control and storage unit 9.
    As can be seen from FIG. 5, the storage surfaces 7 each have grooves 11 arranged in a grid. When a plate-shaped workpiece Wi is lifted off, adhesion to the storage surface 7 caused by aerodynamic effects can occur, which makes lifting the workpiece Wi difficult and is prevented in a simple manner by the grid-like arrangement of the grooves 11.
    As mentioned earlier, in modern
    Manufacturing equipment tracks the movement, the location and the processing status of individual workpieces Wi that pass through the manufacturing facility. This monitoring can be carried out, for example, using transponders, RFID chips or other types of sensors which are arranged on the workpieces Wi and / or along the production lines. The control and storage unit 9 is connected via an interface to the control of the other sections of the production device and thus receives data records about individual workpieces Wi that are fed to the storage area and thus also knows, for example, the dimensions of the workpiece Wi in question. The control and storage unit 9 also has data on the current storage locations of plate-shaped workpieces Wi on / 15 the storage surfaces 7 of the receiving magazine 1. The control and storage unit 9 can thus compare the dimensions of supplied workpieces W i with free storage surfaces 7 and an extension movement initiate a free storage space 7. Subsequently, the depositing movement of the pickup 6 is controlled so that the workpiece Wi in question is deposited on the intended storage surface 7.
    Although mostly information about the type and properties of the workpiece Wi supplied to the storage area is available, the position of the workpiece W i on the receiving table 3 can nevertheless vary, for example by being fed to the receiving table 3 rotated about a vertical axis. Therefore, position sensors are provided on the receiving table 3, which can be designed as simple distance sensors, for example, which are directed against an end edge of the plate-shaped workpiece Wi in order to be able to detect a rotated position. The pickup 6 can subsequently pivot the workpiece Wi accordingly in order to enable a precisely fitting and space-saving storage on a storage surface 7. After a workpiece Wi has been deposited on a storage surface 7, the data on the available storage surfaces 7 are updated accordingly. As soon as the control and storage unit 9 receives the request for the removal of a specific workpiece Wi from subsequent sections of the production device, the storage location of the workpiece Wi in question is called up, the corresponding storage surface 7 is extended into the removal area and the pickup 6 in the removal area is controlled accordingly, so that in a removal movement, the workpiece Wi is lifted from the extended storage surface 7 and placed on the conveyor 8.
    In this way, a device for the intermediate storage of plate-shaped workpieces is provided, which not only permits simple and gentle stacking of plate-shaped workpieces Wi, but in particular also enables integration into automated production facilities.
