Definitions

  • the invention relates to a device and a method for aligning workpieces, which are preferably at least partially made of wood, wood materials, plastic or the like, according to the preamble of claim 1.
  • Alignment stations of the type mentioned are used in the prior art to bring workpieces that are conveyed on a conveyor in a well-defined position. This ensures that the workpieces in a downstream processing station, such as a continuous saw or a Doppelendprofiler, are processed with high precision.
  • a generic alignment station has the Applicant sold under the name TAL 352. This is equipped with cameras to detect the position of the arranged on a conveyor workpieces when stopped conveyor. On the basis of the detection result, the workpieces are brought by two aligners in a desired position, in order to be subsequently promoted.
  • the invention is based on the idea to further develop the device such that the conveyor does not necessarily have to be stopped when detecting and aligning the workpieces.
  • the invention provides that the alignment device has at least one alignment element, which is movable in the direction of passage at least within limits. In this way, the workpieces to be aligned can be conveyed even in the direction of passage even during the detection and alignment process, ideally with the same speed. As a result, the throughput of the device and a total system containing them increased drastically, without sacrificing the precision of the alignment must be taken into account.
  • the at least one alignment element is movable transversely to the direction of passage, namely simultaneously to a movement of the at least one alignment element in the direction of passage.
  • the alignment elements may perform the alignment operation transverse to the direction of travel while moving in the direction of travel along with the workpieces to be aligned.
  • the at least one alignment element can take on a variety of forms and, in the structurally simplest case, be formed by at least one sliding element. According to one embodiment of the invention, however, it is provided that at least one alignment element is designed as a gripping element. In this way, the workpieces' can be guided especially safely.
  • the use of a gripping element allows the workpieces to be pushed not only in a first direction, but optionally also retracted in an opposite second direction, for example, to correct an error in a first alignment operation.
  • the use of a gripping element allows a safe transfer of the workpieces to downstream devices.
  • the number of alignment elements is not particularly limited in the present invention. According to one embodiment of the invention, however, it has proved to be advantageous that at least two alignment elements are provided which are movable independently of one another at least in the direction of passage.
  • the throughput of the device according to the invention can be further increased, for example by operating the independently movable alignment elements alternately. For example, in such alternate operation, a first (pair of) alignment member (s) may grip and align a workpiece during its travel motion while a second (pair of) alignment member (s) simultaneously provide a return stroke performs to take over the subsequent workpiece. As a result, the distance between the successive workpieces can be reduced, with a corresponding increase in the throughput.
  • the device according to the invention can be provided in the context of the invention to compensate only a transverse displacement of the workpieces on the conveyor.
  • at least one side of the conveyor at least two alignment elements are provided which are independently movable at least transversely to the direction of passage. In this way, the workpieces to be aligned can both be moved and rotated, whereby any occurring position errors can be corrected.
  • the device has a second conveying device downstream of the conveying device, wherein at least one aligning element can be moved in the direction of passage in at least sections in the region of the second conveying device.
  • at least one aligning element can be moved in the direction of passage in at least sections in the region of the second conveying device.
  • the workpiece is actuated, in particular gripped, before the position is detected by the alignment device. This ensures that the position of the workpiece after its detection is not undesirably changed by the action of the alignment, which would make the detection result useless.
  • FIG Fig. 1 and 2 An apparatus 1 for aligning workpieces 2 according to the present invention is shown schematically in FIG Fig. 1 and 2 shown.
  • the device 1 is primarily used for conveying and aligning workpieces 2, which consist at least in sections of wood, wood materials, plastic or the like, as they are processed in the field of furniture or kitchen industry, but also in the field of flooring industry.
  • workpieces 2 consist at least in sections of wood, wood materials, plastic or the like, as they are processed in the field of furniture or kitchen industry, but also in the field of flooring industry.
  • other applications or types of work are conceivable within the scope of the present invention.
  • the device 1 has a conveyor 10 for conveying the workpieces 2 in a passage direction, the in Fig. 2 is indicated by arrows, which are in Fig. 2 extend from left to right.
  • the conveyor 10 may be configured in many different ways and comprises in the present embodiment, a plurality of belt conveyors 12. However, chains, sliding surfaces and other conveying elements may be used individually or in combination.
  • the device 1 has a detection device 20 for detecting a position of the conveyed on the conveyor 10 workpieces 2.
  • the detection device 20 in the present embodiment, two cameras 22, which are designed for example as digital or CCD cameras and with a control device not shown in detail are in communication.
  • the cameras 22 are each arranged on a portal 24, which extends transversely to the conveyor 10, so that the Cameras can detect the position of the workpieces 2 from directly above the conveyor 10.
  • the device 1 has an alignment device 30, which has two alignment elements 32, 34 in the present embodiment.
  • the alignment elements 32, 34 are configured in the present embodiment as gripping elements which have, for example, a forceps-like shape whose opening faces the workpieces 2 conveyed on the conveyor 10.
  • gripping elements which have, for example, a forceps-like shape whose opening faces the workpieces 2 conveyed on the conveyor 10.
  • suitable means for example top pressure device and / or vacuum device.
  • the alignment elements 32, 34 are arranged on a guide 36, along which they can be moved in the direction of passage, preferably independently of one another.
  • the alignment elements 32, 34 are arranged on the guide 36, that they are movable transversely to the passage direction, namely simultaneously to a movement of the alignment in the direction of travel and also independently.
  • the alignment elements 32, 34 are arranged transversely to the passage direction on not shown guides and positioned along this motor.
  • the alignment elements 32, 34 are also connected to the control device not shown in detail, so that the movement of the alignment elements 32, 34 can be controlled longitudinally and transversely to the direction of passage on the basis of the operation of the conveyor 10 and the detection result of the detection device 20.
  • a second conveyor 40 is provided which in Fig. 1 and Fig. 2 only partially and shown in broken lines. As in Fig. 1 is best seen, is the travel of the gripping elements 32 and 34 (which is defined by the guide 36) overlapping to the conveying path of the second conveyor 40 is arranged.
  • the aligned workpieces 2 are conveyed on the conveyor 10 in the direction of passage.
  • the alignment elements 32, 34 are placed on the guide 36 in a standby position and, as soon as the workpiece 2 to be aligned has reached a predetermined position, accelerates to the conveying speed of the workpiece 2. Then the gripping elements 32, 34 are moved transversely to the direction of passage and grasp the workpiece 2 to be aligned.
  • the workpiece 2 to be aligned is conveyed under the portals 24 in this state, and the cameras 22 detect the actual position of the workpiece 2 on the conveyor, for example by optical image acquisition and subsequent digital evaluation of the acquired image in the control device. If the actual position of the workpiece 2 deviates from the desired position, the alignment elements 32, 34 are moved transversely to the direction of passage under the control of the control device and the workpiece is thus brought into a desired position. Also during this process, the alignment elements 32, 34 move in the direction of passage, and depending on the application, if necessary, can also be used with a reduced conveying speed.
  • the workpiece aligned in this way is transferred from the alignment elements 32, 34 to the downstream, second conveyor 40, wherein the gripping elements 32, 34 release the workpiece 2 only when the second conveyor 40 has gripped the workpiece safely, so as to ensure that the achieved target positioning is maintained.
  • a desired processing can now be carried out.
  • At least one alignment element is provided on opposite sides of the conveyor 10 in each case.
  • guide 36 it would be possible, in addition to the in Fig. 2 shown guide 36 to provide a further guide, which is arranged on the opposite side of the conveyor 10.
  • This additional guide can accommodate further alignment elements, which operate in an analogous manner to the alignment elements 32, 34 described above, wherein also in this case an alternating operation between the two opposite sides is advantageous.
