Definitions

  • the invention relates to a device for guiding the workpieces in an automatic woodworking machine, in particular for processing squared timber for construction purposes, according to the preamble of claim 1.
  • the guide device forms an essential part of a machine system for machining, which is also referred to as a joinery system or woodworking center.
  • a machine system for machining which is also referred to as a joinery system or woodworking center.
  • several common movable tensioning carriages are provided, which form a common support level and a common stop level.
  • the guide device With the guide device, the workpiece is not only brought into the right place and held for processing, but, depending on the processing, is also moved extremely precisely during this, this movement influencing the processing result.
  • the guide device thus forms one of the five axes of movement of the CNC-controlled system, for example. So it is it is clear that the workpiece must be clamped firmly and with a clear spatial reference to the clamping carriage.
  • a guide device of the type described in the introduction is known from European patent application 0 267 156.
  • the tensioning carriages each have a vertical stop rail and a horizontal support rail.
  • a clamping cylinder With the help of a clamping cylinder, the workpiece is pressed against the stop rail and pressed onto the support rail from above by means of a clamping rail.
  • the clamping rail can be folded up using a swivel cylinder to place and remove the workpiece.
  • this known clamping rail has a spindle drive or a clamping pad that can be placed under pressure on the contact surface with the workpiece.
  • Clamping a workpiece on the clamping carriage is therefore relatively cumbersome, because the clamping rail must first be lifted up and the clamping cylinder must be moved on the support rail in accordance with the width of the workpiece.
  • the clamping devices are also built to be relatively wide. The clamping rail interferes with the machining of the workpiece side on which it rests.
  • the invention has for its object to equip the clamping carriage with clamping devices that make it easier and faster to clamp the workpiece and that together form a compact structural unit.
  • the clamping carrier now plunges further into the support plane, the workpiece clamped between the stop and the clamping member is placed in a direction perpendicular to the clamping forces, ie with the aid of the clamping friction forces, placed on the support plane.
  • the same effect is achieved as if the workpiece were pressed firmly onto the support plane in a known manner.
  • Another advantage is the fact that the initial position of the clamping beam before the clamping movement is always the same, ie does not depend on the height or thickness of the workpiece.
  • Both tensioning processes take place automatically one after the other.
  • the interaction of the clamping devices of a plurality of clamping carriages straightens a beam that is curved or twisted, ie. H. it regains its theoretically correct shape and can therefore also be edited precisely.
  • the workpiece advantageously does not rub against the stop in the second clamping step, since this moves in the clamping direction. The workpiece is thus fixed more securely and precisely in the clamping position.
  • the support plane of the individual tensioning carriage is preferably formed by support supports spaced apart in the direction of travel.
  • the tensioning beam is guided between them and immersed in a lifting cylinder that supplies the tensioning force. driven.
  • a suitable sliding guide ensures that the tensioning movement of the tensioning beam is parallel to the support plane and to itself.
  • the clamping member be guided along the clamping carrier by means of an endless chain and can be tilted outwards at its free end by deflecting the chain.
  • the support level and the clamping beam will be placed horizontally, in which case it would be necessary to lift the workpieces over the upward clamping element. This is particularly unfavorable if the workpieces are placed on the forklift.
  • the deflection point of the chain at the end of the tensioning bracket is designed so that the tensioning element attached to the chain can be guided around at least a little, it swivels outwards and dips below the support level, so that the loading path is free.
  • the tensioning member is pivotably mounted with respect to a chain link about an axis perpendicular to the chain plane and is supported on a further chain link on the side opposite the stop by means of an articulated support.
  • the articulated support is preferably designed to be adjustable in length in order to be able to adjust the tensioning element at right angles to the tensioning support.
  • this solution has the advantageous consequence that the rod ends attached to chain links spread out at the deflection point of the chain, the joint arrangement stretches somewhat and thereby swivels the tensioning member faster and further downward.
  • the chain is expediently driven by a hydraulic motor. Its adjustable maximum torque determines the clamping force.
  • the clamping devices be arranged on an arm which is pivotally mounted on the clamping carriage about an axis pointing in the direction of travel.
  • the support beams form the swivel arm. They are connected to each other and thus form a swivel scaffold in which all other essential components of both clamping devices - clamping bracket, stop, clamping element and the clamping drives - are integrated.
  • the swivel movement can be carried out by means of a lifting cylinder. It is therefore not necessary to loosen the clamping devices, but rather they are pivoted together with the clamped workpiece, so that this reaches a precisely defined pivot position without changing the shape and can be further processed immediately if the machine tool is appropriately programmed. Multiple swiveling back and forth is possible during the entire machining cycle, since there is hardly any loss of time during swiveling.
  • a box section tube 2 is fastened, to which prism rails 3 are welded on both sides, which represent the guideway.
  • a tensioning carriage 4 runs with a plurality of not shown, prestressed rollers on the prism surfaces, i. H. it moves perpendicular to the plane of the drawing and is driven by a motor 5 or other drive means.
  • a base frame 6 is attached to the tensioning carriage 4, which essentially consists of two parallel plates. Between these there is a swivel arm 7 which can be swiveled on swivel pins 8 from its horizontal into a vertical position.
  • the swivel arm is provided at the top with two support strips 9 made of hard rubber or a plastic.
  • a wooden beam 10 to be machined lies across this support ledge and is clamped between a stop 11 and the pressure plate 12 of a tensioning element. With the same clamping arrangements, the beam is clamped in total on several clamping carriages. By folding up the swivel arms 7, it is also accessible on the underside for machining tools on the length ranges between the clamping arrangements.
  • the swivel arm 7 consists of two parallel plates 13, on the upper edge of which a support flange 14 is folded outwards.
  • the support strips 9 are attached to the support flanges.
  • the plates 13 are each fastened to the side faces of a C-profile rail 15, which to a certain extent forms the backbone of the swivel arm 7. Because of the bearing arrangement, the fastened section of the plates 13 does not reach their full height, rather the plates have a rectangular cutout at the upper left corner (FIG. 1). In the area of its lower edge, the plates 13 are connected to one another by a base plate 16.
  • the base frame 6 has a U-shape in plan view.
  • Two bearing plates 17 form the legs and are connected to one another by a web 18. Furthermore, a fastening plate 19 serves to connect and stiffen the bearing plates 17.
  • the C-profile rail 15 is mounted in the bearing plates 17 by means of the pivot pin 8.
  • bearing rings 20 are inserted into the bearing plates 17 and, on the other hand, fastening rings 21 and 22 are also welded to the C-profile rail, which hold the bearing pins 8 firmly. Since the space inside the C-profile rail must remain free, a continuous pivot pin is forbidden.
  • an eye consisting of two levers 23 is welded to the C-profile rail 15, on which the piston rod 24 of a lifting cylinder 25 engages. The lower end of the lifting cylinder is fastened to the downward-reaching part of the base frame 6 by means of a cross bolt 26.
  • the tensioning support 30 can move up and down in the swivel arm 7 according to FIG. 1 in the direction of the arrow.
  • the cross-section of the tensioning beam is shown, inter alia, in FIG. 3. It consists of two U-profile sheets 31 and 32, which are fastened to one another with their web surfaces.
  • the U-profile 31, which is open at the top, consists of a stronger sheet metal. It is responsible for the supporting function. It is screwed to a slide 34 by means of an end flange 33.
  • the U-profile plate 32 the outline of which results from FIG.
  • the slide has bevelled edges on the left end face and is also fastened to the slide 34 with these.
  • the slide has grooves on the side.
  • the folded edge strips of the C-profile rail 15 engage in this, which thus serves as a guide for the slide 34.
  • the slide has a protrusion 35 protruding at a right angle.
  • the piston rod 36 of a lifting cylinder 37 which is located in the C-profile rail 15 and the lower end of which by means of a cross bolt 38 at the lower end, is fastened to this the C-profile rail 15 is mounted.
  • the tensioning support 30 can be moved parallel to itself and to the support strips 9, namely up and down according to FIG. 1.
  • a double chain 39 is guided in the tensioning support 30.
  • the upper section between a deflection roller 40 and a deflection piece 41 made of plastic runs in the U-profile plate 31.
  • the chain is guided downward, placed around a sprocket 42 and returned to the deflection piece 41 via a tensioning piece 43.
  • This lower chain section runs in the U-profile plate 32.
  • the sprocket 42 sits on the shaft of a hydraulic motor 44. This is fixed to the U-profile plate 32, as are the other deflection parts 40, 41 and 43 between the legs of the U- Profile sheet 32 are stored or held.
  • a pressure piece 49 is mounted, which carries the pressure plate 12 already mentioned and is supported on the other hinge piece 47 via a length-adjustable articulated support 50. This can be clearly seen in FIG. 1.
  • This tensioning element attached to the double chain 39 with its pressure plate 12 interacts with the stop 11 which, like the entire tensioning support 30, is fastened to the slide 34. If there is a workpiece between the pressure plate and the stop, the hydraulic motor 42 stops while maintaining its set maximum torque. 1 is activated in the horizontal direction.
  • the second tensioning device is activated by actuating the lifting cylinder 37 in the sense of a retracting movement of its piston rod 36.
  • the entire tensioning support 30 is thereby moved downward in the direction of its sliding guide. This is possible because not only the sheet metal profiles 31 and 32 can move between the plates 13 of the swivel arm, but also the stop 11, the pressure plate 12 and the other parts of the tensioning element with regard to their width extent fit into the gap formed by the support strips 9. Even in the initial position of the tensioning support according to FIGS. 1 and 3, the stop 11 and the pressure plate 12 already engage between the support strips 9.
  • both the support strips and all of the tensioning elements installed in the swivel arm also pivot. If the hydraulic motor 44 protrudes laterally beyond one of the bearing plates 17 due to its design, a corresponding recess must be provided on the latter, so that the pivoting process is not hindered.
  • the operation of the clamping elements is independent of the swiveling process. So you can swivel in the cocking position. If several clamping arrangements of different clamping carriages attack on a beam, all swivel arms swivel at the same time. Since the stop plane, i.e. H. the surface of the stops 11, and the support plane, d. H. the surface of the support bar 9, in the pivoted position are again precisely defined, the initial values for machining are also fixed in the pivoting position.
  • a main advantage of the invention is that the workpieces can be placed on the support strips 9, without having to swivel away a terminal strip crossing above.
