Definitions

  • the invention relates to a device and a method for processing edges of plate-shaped workpieces.
  • plate-shaped workpieces are used in particular in the furniture industry.
  • wood-based materials but also wood-containing materials, such as chipboard, are processed, whereby plate-shaped intermediate products, which are usually already coated on their flat sides, are first cut to the format desired for further processing and then processed in the area of their narrow sides, including in particular the provision of suitable coatings on the narrow sides referred to below as edges is to be understood.
  • This processing of the edges of the plate-shaped workpieces cut to the desired format often takes place in so-called edge circles.
  • the workpieces are fed individually to the conveyor circuit, conveyed in the circuit until the processing of all edges of the respective workpiece to be machined is completed and then removed from the conveyor circuit.
  • a disadvantage of known conveyor circuits is that the individual processing units for edge processing along the conveyor circuit and conveyor devices, which are part of the conveyor circuit, can process or convey plate-shaped workpieces with different dimensions at different speeds.
  • the adjustment of the individual components of such a device to an optimal throughput is only possible to a limited extent, since plates of different dimensions are to be processed regularly in such devices. I.e. If the individual units are tuned to be able to process plates of a certain dimension in such a way that the capacities are matched to one another in such a way that there is no bottleneck or jam at any point in the conveyor circuit, this tuning no longer applies if workpieces are included other dimensions are to be processed, i.e. there is a jam, for example in front of a processing unit, because this processing unit can no longer process the workpieces with the new dimensions at the same speed as the workpieces with the old dimensions, but the other components of the conveyor circuit continue to reach the old processing capacity.
  • the invention is therefore based on the object of demonstrating a device and a method for processing edges of plate-shaped workpieces, which enables uniform utilization of all the individual elements of the device and thus optimal utilization of the entire device.
  • the method according to the invention provides for the dimensions of the workpieces to be fed into the conveying circuit before they are fed Detect and determine the order in which the workpieces are fed into the conveyor circuit, depending on the dimensions of the workpieces recorded.
  • the device according to the invention has a loading device which is set up to determine the sequence in which the workpieces are fed into the conveying circuit as a function of the dimensions of the workpieces.
  • one element of the conveyor circuit works in such a way that a certain number of pieces can be processed per unit of time and another element of the conveyor circuit in such a way that a certain running distance edge length per unit of time can be processed
  • the workpieces are put together in such a way that workpieces with short ones to be worked follow edges on workpieces with long edges to be machined and vice versa.
  • the device that can handle a certain number of workpieces per unit time is not properly utilized because workpieces with long edges jam in front of the device, which can process a certain edge length per unit time.
  • the conveyor circuit is advantageously designed in such a way that in each case one edge of a workpiece is machined when it is conveyed along a processing section, that is to say a section of the section of the conveyor circuit in which the edge is processed by a processing unit.
  • a processing section that is to say a section of the section of the conveyor circuit in which the edge is processed by a processing unit.
  • each will Conveying a certain number of workpieces along the processing line achieves an average uniform ratio between the edge length to be machined and the number of pieces, which would not be the case if the long edges of all workpieces were processed first and then the short edges of the individual workpieces in a further run of the conveyor circuit .
  • This would have the consequence that the ratio of the edge length to be machined to the number of workpieces would change significantly between the two runs of the conveyor circuit, which in turn would overload the capacities of individual units while at the same time reducing the utilization of other units.
  • feeding in groups is also possible.
  • the group feed can be carried out, for example, using a sorting station, in which the workpieces are initially grouped together in such a way that the dimensions relevant to the capacities in the conveyor circuit are as constant as possible on average for the respective group, i.e. that the compilation is carried out in such a way that a fluctuation in the dimensions from group means to group means is minimized, for example, it is avoided to assemble a group only from very small workpieces, that is to say workpieces with a large ratio of the number of pieces to the edge length to be machined.
  • the Figure 1 shows a schematic representation of an exemplary device according to the invention.
  • the funding cycle 1 is composed of two oppositely working conveyors 8 and 9 and two translators 12 and 13, which workpieces can transfer from one conveyor to the other.
  • the conveyor 8 runs along a processing machine (not shown), ie a section of the conveyor 8 forms the processing section 2.
  • the conveying circuit also has means (not shown) for changing the orientation of the workpieces between their passes through the processing section 2, it is possible to design the processing section 2 such that only one edge 4 of the workpiece is processed per conveying of a workpiece through the processing section .
  • the workpiece then passes through the translator 12, the second conveyor 9 and the translator 13, whereupon it again arrives at the conveyor 8 and is conveyed through the processing line again. If the orientation of the workpiece between the conveyors along the processing section 2 is changed, another edge 4 of the respective workpiece 3 is machined.
  • the means for changing the orientation of the workpieces 3 can basically be located at any position of the conveyor circuit.
  • a removal station (not shown) can be provided, which can in principle be located at any point in the conveyor circuit 1.
  • the conveyor 9 is designed in such a way that it can further convey the workpieces 3 beyond the transfer point with the translator 13, so that a section of the conveyor 9 no longer belongs to the conveyor circuit 1, but rather a removal section represents, from which the workpieces can be removed.
  • the loading device has a loading station 6 and a sorting station 7.
  • the workpieces are put together in groups according to their dimensions, in the example shown there are groups of four workpieces in each case, which are put together in a rectangular grid into images by the loading station 6 and fed in groups to the conveyor circuit 1.
  • the conveying circuit 1 In the conveying circuit 1, they first reach the singling station 11, which separates the workpieces 3 fed in groups before they are individually conveyed and processed by the conveyor 8 along the conveying path 2.
  • a conveyor station 10 connects to the conveyor 8, in which the individual workpieces 3 are grouped again. These groups are then transferred to the translator 12, conveyed back by the conveyor 9 and fed back to the singling station 11 by the translator 13.
