Definitions

  • the invention relates to frame presses with the features of the preamble of claim 1 or 2 or 3.
  • Frame presses for wooden frames are known (DE-A-29 24 257), in which the individual frame parts are pressed together to form a frame by means of power-driven press corners and fixed systems.
  • Such presses have a fixed longitudinal pressure bar or support and a movable longitudinal pressure bar or support with longitudinal and transverse supports for the two frame parts arranged at right angles to one another and in the press.
  • the frame parts are pressed by three press corners connected to the fixed or movable pressure beam; the press corners are fed with the help of adjustment motors.
  • the setting of the press corners on the frame parts arranged at right angles to one another is achieved by sensing elements on the press corner assigned to the fixed pressure beam and on the lower press corner assigned to the movable pressure beam. For this it is necessary, in addition to. H.
  • a receptacle arranged parallel to the fixed pressure beam and at the lower end of the press, into which measuring workpieces corresponding to the frame parts are inserted before pressing.
  • the respective pressing corner is moved upwards and is only stopped when the sensing element has moved beyond the frame part.
  • a pair of sensors is scanned. The setting for the dimension of the frame part arranged at right angles thereto is carried out in an analogous manner.
  • the measuring workpieces are removed and the frame parts to be pressed are inserted into the frame press (instead of a separate measuring workpiece, the frame part to be pressed later can also be used).
  • the insertion of frame parts in the form of measuring workpieces in receptacles only required for setting purposes and the subsequent removal of the measuring workpieces as well as the separate insertion of the frame part to be pressed into the frame press is time-consuming and cumbersome and thus impairs the performance of the frame press as well as the simple one Service.
  • the object of the invention is to design frame presses of the generic type in such a way that the frame parts can be inserted directly into the frame press and pressed immediately. without a separate measuring process on the frame parts outside the machine being necessary and without corresponding measuring workpieces or the frame parts having to be inserted or positioned twice.
  • the stop rail already takes up the frame part in the plane in which the individual frame parts are pressed to the frame and is designed to be displaceable in this plane. In this way, the frame parts already take the position required for the pressing process when they are inserted into the frame press, so that the setting and pressing process is carried out automatically once the frame parts are inserted into the frame press.
  • a movable support instead of the fixed support Carrier and a fixed stop rail provided instead of the movable stop rail, so that in this case not the frame part is moved under the press corner, but vice versa the press corner under the frame part fixed in this case.
  • a single component is provided which is a movable stop rail with a press corner attached to it.
  • this press corner or the pressure cylinder with the pressure member is designed to be displaceable or pivotable on the press corner, so that the frame part is inserted unimpeded can be.
  • Two pressure elements are provided for each frame part, which fix the frame parts automatically, preferably pneumatically, to the machine stops when they are inserted.
  • the stop rail is moved via a hydraulic cylinder with a fixed, adjustable stroke towards the press corner of the fixed beam. This stroke is dimensioned so that the pressure plate of the press corner is above the vertical frame part, so that when pressing the pressure plate presses the frame part vertically downwards.
  • the height setting of the press corner is determined with the help of the sensing device, which takes over the scanning of the upper edge of the frame part.
  • the drive for the press corner on the fixed support moves the press corner with the sensing device downwards.
  • the sensing device When the sensing device has reached the height of the upper edge of the vertical frame part, it signals a stop for the drive, so that the press corner is stopped. In this position, the pressure plate of the press corner has reached the working position and is ready to carry out the pressing process.
  • the lower press corner of the movable support automatically goes up a certain distance (pneumatically controlled) when the press is opened, i.e. after a pressing process has ended, so that the horizontal lower frame part can be inserted on the base support against stops without hindrance
  • Base carrier a pneumatically operated pressing device for positioning the frame part and a pressure cylinder arrangement with a pressure plate and attached sensing device are provided.
  • the pressure plate with the sensing device arranged thereon is automatically raised by pneumatic control and brought into the scanning position by means of pneumatic control.
  • the sensing device scans in the manner described above in connection with the vertical frame part explaining the right upper edge of the horizontal frame part and signals the determination of the drive for the movable support with a lower press corner. As soon as the vertical stop rail is moved, the press corner is moved downwards by pneumatic control and takes up the press position.
  • Fig. 1 the frame press is shown schematically in an overall view.
  • Side stands 2, 3 are rigidly fastened with a stationary base support 1 and are connected to a rectangular frame via a head rail 4.
  • the movable support for the pressing elements is designated 5, the fixed support 6.
  • a movable stop rail 7 can be moved towards and away from the fixed support 6 in the frame plane and is guided on the base support 1 and on the head rail 4.
  • the drive of the stop rail 7 takes place, for. B. via a hydraulic pressure cylinder (not shown), which moves the drive rail 7 by a predetermined, adjustable distance to the fixed support 6.
  • 8 with a stationary, horizontal support is designated, with which the vertical support 6 is rigidly attached at the lower end and which, together with the head rail 4, takes over the guidance of the movable support.
  • the movable support is further guided along a drive rail 9 fastened to the two side stands 2 and 3 via a motor drive (not shown) in the frame plane.
  • a motor drive (not shown) in the frame plane.
  • an upper press corner 10 with a pressure cylinder and pressure plate 11 and with a contact surface 12 is arranged such that it can be moved in height.
  • the height of the press corner 10 is via a (not shown) motor drive by means of drive chain 13 and sprockets.
  • a height-displaceable right upper double press corner 14 is fastened in a corresponding manner, which has two mutually perpendicular pressure cylinders with pressure plate 15, 16 and with a contact surface 17 for the ends of the two frame parts abutting here.
  • This press corner 14 is also designed to be vertically displaceable via a drive chain 18 and a drive (also not shown).
  • the movable carrier 5 also receives a lower press corner 19, which has a pressure cylinder with a pressure plate 20 and a contact surface 21 for the frame parts.
  • the individual frame parts of the frame to be pressed in the frame press are designated by 22, 23, 24 and 25.
  • the frame part 22 lies against the stop rail 7 and stands on a lower stop 26 of the stop rail 7.
  • the upper edge of the stop 26 lies above the upper edge of the base support 1, so that the frame part 24 can penetrate from the side into the pins of the frame part 22 during the pressing and then the frame part 22 is pressed again in the vertical direction to complete Interlock and penetrate the pin on both sides.
  • a sensing device 30 which can be an optical-electrical sensor device of known construction, is attached, which senses when the stop rail 7 moves on the carrier 6 to the upper edge of the frame part 23. If the sensing device 30 does not detect the presence of the frame part 22 during operation, it is signaled that the press corner 10 is moved downwards together with the sensing device 30 until the sensor detects the upper edge of the frame part 22 and thus the command is triggered, the downward movement of the Press corner 10 adjust.
  • the pressure plate 11 of the frame corner 10 is at the desired height distance from the upper edge of the frame part 22.
  • the sensor 30 signals that a hydraulic drive (not shown) is actuated, which moves the stop rail 7 by a fixed, adjustable stroke distance onto the fixed support 6, so that after this movement of the stop rail 7 has been completed, the pressing position of the pressing corner 10 is related is taken up on the frame part 22.
  • a guide bar 31 is fastened, in which the arm 28 is movably guided up and down.
  • a downward holder 32 is connected, which receives a plate 33, on which a pressing member 34 is fastened via an articulated connection 35.
  • the pressing member 34 is connected to a pneumatic drive 36.
  • the head of the pressing member is automatically pressed against the frame part (preferably pneumatically) when a frame part is inserted into the press, so that the latter is positioned in the frame press.
  • Such pressure members are known per se and two such members are provided per frame part.
  • a plate 37 is provided around the base support 1, which receives a drive cylinder 38 (pneumatic) with a pressure plate 39, on which a sensing device 40 is attached. The sensing device 40 can thus be displaced together with the movable carrier.
  • a pressure element 41 is fastened on the plate 37, which corresponds to the pressure element 34 described above.
  • the sensing device 40 is arranged below the upper edge of the base support 1 at the start of the work process.
  • the press corner 19 is arranged in the raised position at the start of operation, so that the frame part 24 can be inserted into the press unhindered.
  • the sensing device 30 When the sensing device 30 reports that the upper edge of the frame part 22 is not detected in the current position, it signals a downward movement of the press corner 10; the pressing corner 10 is moved downwards until the sensing device 30 has reached the level of the upper edge of the frame part 22. Then the sensing device 30 signals to stop the drive and to stop the press corner 10. Simultaneously with the press corner 10, the vertically acting part 15 of the right press corner 14 has been moved downwards to the same extent. When the press corner has assumed this position, the stop rail 7 is moved from the position shown in FIG. 1 to the right against the fixed support 6 and its press corner 10 via a working cylinder (hydraulic cylinder) (not shown).
  • a working cylinder hydroaulic cylinder
  • the cylinder stroke is adjustable, and the stop rail 7 reaches the position in which the pressure plate 11 has reached its pressing position above the frame part 22 after the predetermined step has been completed.
  • the sensing device 40 connected to the movable support is brought upwards via the compressed air cylinder 38 and the pressure plate 39 into the scanning position for scanning the frame part 24, and on the other hand the pressing corner 19 - via compressed air cylinders, not shown - Moved down into the working position up to the upper edge of the base support 1.
  • the press corner 19 is automatically brought into the rest position by pneumatic control. Now the sensing device 40 scans the front edge of the frame part 24.
  • the sensing device 40 does not detect the frame part 24, it is signaled that the drive moves the carrier 5 in the direction of the frame part 24. If the frame part 24 is detected by the sensing device 40, the drive of the carrier 5 is switched off. In this position, the pressure plate 20 of the pressure cylinder of the press corner 19 already faces the end face of the frame part 24 for pressing. The pressure plate 16 of the press corner 14 has performed the same movement and has assumed its press position with respect to the frame part 25. The pressing process can be initiated.
  • the press corner 19 can also be designed to be pivotable or foldable on the carrier 5 from the working plane.
  • FIGS. 5 and 6 schematically outline an embodiment of the invention which is modified from the representation according to FIG. 1.
  • a movable stop rail 42 with a press corner 43 is provided instead of the fixed support 6 with press corner 10 and stop rail 7, a movable stop rail 42 with a press corner 43 is provided.
  • the press corner has a carrier plate 44 which has an angle arm 45 pivots at 46.
  • a pressure cylinder 47 with a pressure plate 48 is fastened to the angle arm 45.
  • the angle arm 45 can be pivoted on the support plate 44 from the position 45 'which is firmly drawn into the position indicated by the dashed line, in order to insert the frame part. Otherwise, the method of operation takes place via a sensing device, which scans the frame part, in the manner described above in connection with FIG. 1.
  • the movement can also take the form of a tilting movement or a longitudinal movement, e.g. B. via rack drive.
