Definitions

  • the present invention relates to a panel dividing system for dividing plate-shaped workpieces according to the preamble of claim 1, and a method for operating such a panel dividing system according to the preamble of the independent claim.
  • Such panel dividing systems are available both from the market and from the DE 10 2008 034 050 A1 , the DE 10 2009 038 120 A1 or the EP 2 422 944 A1 known. These panel dividing systems are used to divide large-format panel-shaped workpieces, such as those used in the furniture industry. When operating such panel dividing systems, the divided workpieces must be handled after a processing step, for example in order to send them for stacking or a new processing step. This requires either at least one operator to handle the divided workpieces, or the workpieces are handled by machine support. In the first-mentioned variant, the personnel effort, the resulting burden on the operator and the possible risk of injury are high, whereas with machine-assisted handling there is a risk of high design and construction effort. This entails corresponding acquisition costs and high maintenance costs.
  • the DE 38 40 325 A1 discloses a panel dividing system in which a section of a panel to be divided lies on a side support table during the sawing process. The loose section after the sawing process can then be conveyed back to the feed table.
  • the DE 39 11 639 A1 describes a panel dividing system with a vertically movable buffer.
  • the present invention is therefore based on the object of enabling a fully automatic use of a panel dividing system with simple structural means.
  • the panel dividing system according to the invention has the advantage that it can work fully automatically, which means that a very high level of economic efficiency can be achieved.
  • the panel dividing system is inexpensive and constructed using simple structural means.
  • a workpiece can be transported to a dividing device by means of a conveyor and can be comminuted there into a divided workpiece.
  • the divided workpiece can be buffered in a buffer device before a further division process.
  • the buffer device is designed such that the buffered workpiece can be moved in a second conveying direction, the second conveying direction being oriented transversely to the first conveying direction.
  • the buffer device is not just a storage option, but rather an active device that can move the buffered workpiece in a targeted manner. The buffer device can thus move the workpiece in the second conveying direction towards the feed table or away from the feed table.
  • the expression “across the first conveying direction” is to be understood in the broadest sense.
  • the second conveying direction can thus be oriented obliquely, i.e. at an angle that deviates from the orthogonal, or orthogonally to the first conveying direction.
  • the buffer device can have at least one further conveyor device for moving the buffered workpiece in the second conveying direction.
  • the buffer device can have two conveyor devices for moving the buffered workpiece. This means that smaller conveyor devices can be used, whereby only the conveyor on which the workpiece is located has to be driven to transport the buffered workpiece. If several workpieces are buffered in the buffer device, the separate conveyor devices can be used to handle the workpieces simultaneously but differently.
  • the buffer device can have a first segment, which is arranged laterally from the feed table, and a separate second segment, which is arranged in the area of the feed table, the first segment having a first of the further conveying devices and the second segment having a second of the further ones Funding facilities are assigned.
  • the first segment and the first additional conveyor device can therefore be used to buffer and shift workpieces in the second conveying direction. Buffer space can thus be released in a section of the first segment as required, for example in an area of the first segment adjacent to the feed table, or a workpiece can be brought specifically to the feed table.
  • the capacity of the buffer ie the number of storage spaces for workpieces, is increased, and the order of the workpieces can be changed in the direction of the feed table .
  • the buffered workpiece is transferred to the feed table and, if necessary, the workpiece is positioned.
  • the first segment can also be referred to as the “active workpiece buffer” or “active strip buffer”.
  • the second segment can also be referred to as “lateral handover”.
  • the panel dividing system can have a handling device for handling possibly divided workpieces, for example a robot with a suction gripping device.
  • a handling device for handling possibly divided workpieces for example a robot with a suction gripping device.
  • This can be arranged on a projecting end of a robot arm of the robot and can be used to pick up or grip workpieces.
  • a divided workpiece can be picked up after a dividing process and placed on the buffer device.
  • the divided workpiece can be rotated if necessary.
  • the working area or storage area of the handling device or the robot and the buffer device, in particular the first segment of the buffer device at least partially overlap.
  • an area of the first segment of the buffer device that is adjacent to the feed table is in the working area of the handling device, whereas an area of the first segment that is remote from the feed table is not.
  • An upper side of the first segment or the first further conveyor device can expediently be elevated at least temporarily relative to an upper side of the feed table. This makes the transfer from the first segment to the feed table easier. It is conceivable that the top of the first further conveyor device or the first segment is increased by 5 to 35 millimeters, more preferably by 10 to 30 millimeters, more preferably by 15 to 25 millimeters, more preferably by 20 millimeters.
  • the second segment or the second of the further conveying devices can be designed to be height-adjustable relative to the feed table, or the feed table can be height-adjustable relative to the second segment.
  • the second segment or the second further conveyor device can move between a first position in which an upper side of the second segment or the second further conveying device is arranged below a top side of the feed table, and a second position in which the top of the second segment or the second further conveying device is arranged above the top of the feed table (and preferably at the same height as the first segment).
  • This also applies to the kinematically opposite case, in which the feed table is height-adjustable relative to the second segment.
  • the second segment or the second further conveyor device can be activated in a very targeted manner when a buffered workpiece is transferred from the first segment to the second segment. This makes handover easier. If no transfer takes place, the second segment or the second additional conveyor device can remain in its first, recessed position (or the feed table can remain in its elevated position), so that workpieces can be fed undisturbed in the first conveying direction by the first conveyor device can be done.
  • the first further conveyor device and/or the second further conveyor device can each have a rotating conveyor element. This enables gentle transport of the workpieces, since there is no relative movement in the contact plane between the workpiece and the conveying element.
  • the rotating conveyor element can be a belt or a chain.
  • roller rails can also be used as a conveying element, whereby a slider can drive the workpieces, or where the rollers themselves are driven.
  • the rollers of the roller rails can have an elastic surface, for example in the form of a rubber coating.
  • a displaceable stop can be arranged on the feed table for aligning the workpiece that is initially buffered and then conveyed to the feed table by the buffer device. This makes it possible to create a defined stop for a workpiece without impairing the handling and transport of the workpieces due to a fixed stop. It is advantageous if the stop is displaced between a first position, in which the stop is located below an upper side of the feed table, and between a second position, in which the stop is arranged at least partially above the upper side of the feed table can be.
  • the stop can be displaced in various ways, for example the stop can be designed to be pivotable, extendable or telescopic. It is not necessary for the stop to form a single, continuous stop surface. Rather, for the stop to function, it is also sufficient that several stop sections, for example in the form of pins, are displaced relative to the surface of the feed table.
  • the second segment can have a driver element coupled to the second further conveyor device, with which the divided workpiece can be moved to align it with the stop.
  • the driver element can be coupled to the conveying element of the second further conveying device.
  • the driver element can have a contact section which is displaceable in such a way that it is arranged in a first position below a top side of a feed table and in a second position at least partially above the top side of the feed table.
  • the driver element has an actuator which, when activated, displaces the contact section in such a way that it is arranged at least in some areas above the top of the feed table.
  • the actuator it is conceivable that it is designed as a pneumatic cylinder or hydraulic cylinder.
  • the divided workpiece can expediently be handled by means of a handling device, for example by means of a robot with a suction gripping device. This can be arranged on a projecting end of a robot arm of the robot. Using the handling device or the robot, a divided workpiece can be picked up after a division process and placed on the buffer device. The divided workpiece can be rotated.
  • a handling device for example by means of a robot with a suction gripping device. This can be arranged on a projecting end of a robot arm of the robot.
  • a divided workpiece can be picked up after a division process and placed on the buffer device.
  • the divided workpiece can be rotated.
  • the working area or storage area of the handling device or the robot and the buffer device, in particular the first segment of the buffer device at least partially overlap. In particular, an area of the first segment of the buffer device that is adjacent to the feed table is in the working area of the handling device, whereas an area of the first segment that is remote from the feed table is not.
  • the divided workpiece can be transferred from a first segment of the buffer device, which is arranged laterally to the feed table and buffers the divided workpiece, to a separate second segment of the buffer device, which is arranged in the area of the feed table.
  • the actual buffering of workpieces can therefore take place in a first segment of the buffer device outside the feed table.
  • the first segment can also be referred to as the “active workpiece buffer” or “active strip buffer”.
  • the transfer and, if necessary, positioning of the second workpiece onto the feed table can be done with the help of the second segment, which is arranged in the area of the feed table.
  • the second segment can also be referred to as “lateral handover”.
  • the second segment can expediently be raised relative to the feed table to at least the height of the first segment before or during the transfer of the divided workpiece and its height can thus be adjusted to the first segment.
  • the second segment can thus be raised in a very targeted manner when a workpiece is transferred from the first segment to the second segment. If no such transfer takes place, the second segment can remain in a lowered position in which an upper side of the second segment is arranged below an upper side of the feed table. This means that workpieces can be conveyed undisturbed in the first conveying direction of the feed table.
  • the divided workpiece can be moved on the first segment by means of a first further conveyor device and can be moved on the second segment by means of a second further conveyor device, wherein preferably the second further conveyor device is only activated as soon as a section of the divided workpiece second segment reached.
  • the second further conveyor device is only activated as soon as a section of the divided workpiece second segment reached.
  • rotating operation of the second further conveyor device can be avoided, so that positioning tasks can also be carried out by the second further conveyor device, for example.
  • the divided workpiece can be placed on the feed table by lowering the second segment. This allows the workpiece to be placed gently on the feed table.
  • the divided workpiece placed on the feed table can be moved to a displaceable stop of the feed table and pressed against it for alignment relative to the feed table and / or the dividing device by means of a driver element arranged at least in some areas above an upper side of the feed table.
  • the stop can be displaceably arranged on the feed table.
  • the stop can be displaced in various ways, for example the stop can be pivoted, extended or telescoped.
  • the driver element can be coupled to the second further conveyor device, in particular with a rotating conveyor element of the second further conveyor device. This means that the workpiece can be transported using the second segment and positioned relative to the feed table. The expenditure on equipment is therefore significantly reduced.
  • the divided workpiece lying on the feed table can first be fixed in the aligned state by at least one clamping element, and then the driver element and the stop can be displaced away from the divided workpiece.
  • the driver element presses the workpiece against the stop so that the workpiece is in a clamped state.
  • a clamping element fixes the workpiece so that the clamped position is maintained.
  • the clamping element is connected, for example, by means of a program slide and can feed the divided workpiece to a further dividing process.
