Definitions

  • the above invention relates to a loading or unloading device for plate-like workpieces for a hot plate press.
  • Such presses with a work space which are used for finishing plate-shaped workpieces for the furniture industry, have a loading device on their input side, which consists, for example, of a drivable belt, and an unloading device is arranged on the output side of the press.
  • Known presses have loading devices and Unloading devices that prevent these devices from working at the same time, so that the known devices are only moved into the press with the unloading device and after emptying the press space there is the possibility of inserting the plate-shaped workpieces with a second device, namely the loading device, and subsequently , this device must be extended empty from the press. Carrying out the loading and unloading process with various devices takes considerable time and the efficiency of the press drops considerably.
  • the object of the above invention is to provide a device with which it is possible to load a press of the type mentioned from one side and to unload the pressed workpieces on the same side of the press and to ensure that both the loading processes and the unloading operations are carried out very quickly in order to prevent the plate-shaped workpieces from coming into contact with the heated lower press surface very gradually and slowly and to make it possible for the workpieces treated in the press to be moved out of it quickly without running any risk that the sensitive surfaces of the finishing material will be damaged.
  • the object according to the invention is achieved in that at least on one side of a hot plate press there is a carriage which can be moved into and out of the press room, that this carriage has an upper surface for inserting the plate-shaped workpieces into the press and on the underside of the carriage a second level is provided, which is equipped with gripping members for gripping, lifting and extending the pressed workpiece.
  • the plate-shaped workpieces which are arranged on the upper surface of the mobile trolley, can be placed on the lower plate level of the press without any gradual exposure to heat before the pressing force is applied, and also by the provision of lifting devices on the underside of the reciprocating trolley there is the possibility of lifting the finished plate-shaped workpieces from the lower press plate, which makes it possible to move out of the press without sliding contact of the workpieces with the lower plate.
  • the essential advantage is achieved that the device according to the invention, which is used both for the insertion of the workpieces and for the Extending the pressed workpieces is used, the loading process and the extending process are as short as possible in time and a single device is used for both processes, which significantly reduces the costs of these auxiliary devices but at the same time increases the efficiency of the press.
  • the press 1 has an upper heating plate 2. With the help of hydraulic cylinders, this press plate 2 can be lowered for the pressing process.
  • the underside of the press room 3 of the press 1 is closed by a heated press plate 4, which is usually arranged in a fixed manner.
  • a movable loading and unloading carriage 6 is arranged on the inlet side 5 of the press 1.
  • the press 1 and the carriage 6 are arranged above the floor 7 by a corresponding underframe. Since the press does not cooperate with a conventional unloading device on the side provided as the workpiece outlet 8, the press 1 can advantageously be arranged in the immediate vicinity of a wall marked 9 if necessary.
  • the device for loading or unloading the plate-shaped workpieces which is identified overall by 6, is provided on the inlet side 5 of the press 1 and essentially consists of a movable carriage 10 (FIG. 2).
  • the carriage 10 has rollers 11 and 12 with which the carriage can be moved on rails 13, rails which are arranged on both long sides of the press chamber 3 of the press 1.
  • the top of the carriage 10 forms a support plane 15, which is the one or more plate-shaped workpieces 16, which the press room 3 of the press 1st are to be fed.
  • the support level 15 can be designed as a fixed level or can be equipped with an endless belt 17 which is guided over rollers 18 and 19.
  • the carriage 10 has gripping means 20, for. B. a number of pneumatic suction cups, which are arranged above the level 21 of the lower plate 4 of the press 1.
  • the level 15 of the carriage 10 for receiving the plate-shaped workpieces 16 is arranged below the level 23 of the upper press plate 2.
  • the rails 13 are advantageously supported by support columns 22.
  • a roller conveyor 24, which is supported by supports 25, is arranged under the device 6.
  • the roller conveyor 24 is advantageously operatively connected to drive pistons, not shown. These drive pistons enable the roller conveyor 24 to be raised and lowered in the direction of the arrow F for receiving and conveying the pressed workpieces.
  • a drive device which is identified overall by 26, is connected to the carriage 6.
  • the drive device 26 consists, for. B. from a controllable motor and a reduction gear, the z. B. is in operative connection via a toothed rack with a toothed rack, which is arranged parallel to the rails 13 and creates the possibility of moving the carriage 6 into the press room 3 of the press 1 or the carriage from the press 1 to extend.
  • the drive device 26 can cooperate with a positioning device and a position detection device known per se, in order thus to enable a precise and controlled position arrangement of the carriage 6 relative to the press room 3 of the press 1.
  • the carriage 6, which advantageously consists of welded profile pieces or metal pipes, has suction pads 20 on its underside.
  • These suction cups 20 can be connected to a vacuum source.
  • the suction cups 20 are provided with adjustable height in order to ensure that the elastic suction bodies always lie at a low height above the plate-shaped workpiece 16 which is arranged in the press plane 3.
  • the top 15 of the carriage 6 is also arranged in relation to the press 1 in such a way that the plate-shaped workpiece 16 always comes to rest below the lower surface 23 of the plate 2 of the press 1. This ensures that the suction device never comes into contact with the upper surface of the plate 16 in the press space 3 and that the lower surface of the plate 16 (during the insertion process of the carriage 6) does not come into contact with the surface 23 of the lower press plate 2. This prevents the plate-shaped workpieces damage such. B. scratches or impressions during the entry into the press room.
  • the press frame 1 On the long sides of the press 1, parallel to the rails 13, the press frame 1, known from the prior art, has a number of controllable gripping tongs 14 which, after the carriage 6 has entered the press space 3, grasp the plate-shaped workpiece 16 and for a few Lift millimeters from level 15 of the trolley together with the coating laminates, not shown and to be glued on.
  • the gripper-like grippers 14 are only shown schematically in FIG. 3, since such devices for grasping and depositing a plate-like workpiece with the associated coating materials on a lower press plate belong to the general state of the art.
  • the suction cups 20 are controlled (after the carriage 6 has entered the press room 3 of the press 1) in such a way that they on the upper surface of the plate-shaped workpieces 16, which are stored on the lower plate 21 of the press 1, come to rest and, after applying a negative pressure in the suction cups 20, a control process takes place with which the plate 16 is raised by a short amount to enable the carriage 6 to be moved out of the press space together with the raised plate 16 and to prevent the lower side of the workpiece from resting or grinding on the lower press plate 21 of the press.
  • roller conveyor below the carriage 6, which can be raised or lowered to move out of the press room 3 (with the aid of the suction cup 20) to accommodate extended plate-like workpieces.
  • the plates 2 and 4 of the presses 1 are placed at a mutual distance, which enables access to the press space 3 of the press 1.
  • the carriage 6 drives into the plate space 3 of the press 1 together with a prepared plate-shaped workpiece 16, which is arranged on the top 15 of the car.
  • the plates 2 and 4 are spaced apart in such a way that the carriage 6 is given the opportunity to enter the press room 3 of the press 1 without the plate 16 coming into contact with the plate 2 and without the suction cups 20 on the plate plate-shaped workpiece 16, which rests on the lower plate 4 of the press 1, come into contact.
  • the gripper tongs 14, known from the prior art are operated, which are arranged on the long sides of the press plates 2 and 4. These gripping tongs 14, which are not shown in detail, grip the plate-shaped workpiece 16, which rests on the surface 15 of the carriage 6.
  • the plate-shaped workpiece 16 is then raised by a certain amount.
  • the suction cups 20 perform a downward movement and come into operative connection with the surface of the plate-shaped workpiece 16, which rests on the lower press plate 4.
  • the plate-shaped workpiece 16 can be lifted from the lower press plate 4 of the press 1 by a few millimeters.
  • the Carriage 6 extended from the press 1 and the plate-shaped workpiece 16, which was previously held by the suction cups 20, is deposited.
  • the plate-shaped workpiece 16, which was gripped by the gripper tongs 14, is held in a floating position near the upper press plate 2.
  • the plate-shaped workpiece 16 is deposited, which was previously held by the suction cups 20, e.g. B. on the roller conveyor 24 or on another suitable conveyor.
  • the plate-shaped workpiece 16 which was held in the press chamber 4 of the press 1 by the gripper tongs, is placed on the lower press plate 4 in the plane 21.
  • the press 1 is then closed quickly, as shown in FIG. 8, in order to simultaneously transfer heat and pressure to the surfaces of the plate-shaped workpiece 16 and thus to achieve a perfect press result. This is particularly so in those cases in which the plate-shaped workpiece 16 to be processed is to be coated with decorative sheets made of melamine resin.
  • the loading and unloading device 6 according to the invention it is thus possible to dispense with a separate unloading device which would have to be provided on the press outlet side 8 (FIG. 1).
  • the press equipped with the device 6 according to the invention can be arranged in the immediate vicinity of a wall 9, the space requirement for the press is considerably reduced.
  • the device 6 for loading or unloading the plates has been divided according to the invention into two levels 15 and 20 arranged one above the other, that is to say one level 15, which is used for moving the plate-shaped workpiece 16 into the press 1 finds, and in a lower level, the suction cups 20 or similar suitable gripping means for extending the plate-shaped workpiece 16 is equipped.
