Definitions

  • the invention relates to a device for changing spacer elements on a multi-daylight press, which has a vertically arranged support column with support fingers for the spacer elements assigned to the individual levels of the press.
  • spacer elements are arranged between the individual floors.
  • the spacer elements can be plate-shaped, strip-shaped or the like. They are usually placed on areas of the individual floors predetermined for this purpose and are interchangeable so that panels of different thicknesses can be produced with the multi-daylight press.
  • a device of the type described at the beginning (DE-OS 16 53 304) is known, with which spacer strips are inserted into the press from one side thereof, whereby the spacer strips located in the press can be pushed out and removed on the other side of the press.
  • the object of the invention is to simplify the construction and function of a device of the type described in the introduction.
  • the support column in question is movable in the horizontal direction and rotatable about its axis, that two support fingers are assigned to each floor, the mutual spacing of which is smaller than the assigned dimension of the spacer elements and which extend beyond the support column on both sides in that the support column in question can also be displaced in the vertical direction, that the support fingers also run parallel to one another and support the individual spacer elements in a position transverse to the support fingers, and that when the support column moves towards the press, the support fingers protruding from the respective floor between them record, such that when lowering the support column and thus the support finger, the spacer elements are placed on the claws.
  • the new spacer elements are placed on the supporting fingers on one side of the support column and the support column is then moved into the area of the multi-daylight press.
  • the support column is moved to the multi-daylight press in such a way that the empty support fingers on the other side of the support column simultaneously grasp and accommodate all the spacer elements on the different floors, one above the other. If necessary, the support column is then moved away a little from the multi-daylight press and rotated through 180 °, so that the supporting fingers with the new spacer elements lying thereon face the multi-daylight press. Then the support column is moved back to the multi-daylight press until the spacer elements lie on their assigned supports. The support column can now be moved away from the area of the multi-daylight press and the multi-daylight press is ready for operation. This makes it possible to carry out the replacement and removal of the spacer elements on one and the same side of the press.
  • the support column is expediently moved in the horizontal direction with carriages arranged in the region of its upper or lower end.
  • the carriages can run on rails and can be driven with lifting cylinders. This ensures that the support column can not perform any unwanted self-movements, because it is guided at both ends in the assigned car, which are simultaneously moved in the same direction.
  • the upper carriage can have a driven cable winch, on the rope of which the support column is suspended, the lower carriage having a vertical guide for the support column.
  • the support column can thus also be moved in the vertical direction, that is to say in the direction of its longitudinal axis, and can be raised or lowered by a short distance in order to receive or deposit the spacer elements.
  • the vertical guidance of the lower carriages can consist of U-shaped profiles, in which the strip-shaped vertical guide lugs of the support column engage.
  • the guide lugs of the support column are expediently arranged such that they extend orthogonally to the support fingers and protrude above them.
  • the upper carriage has a centering sleeve for a centering pin arranged at the upper end of the support column.
  • the centering pin can be a partially tapered end section of the support column.
  • a rotary drive for the support column can also be arranged on the upper carriage and has a gearwheel which can be brought into engagement with a pinion of the rotary drive.
  • a bushing which can be rotated with respect to this with separate guide tabs is arranged at the lower end of the support column, so that the support column held on the upper carriage with the cable winch and guided on the lower carriage with the rotary drive around it Longitudinal axis can be rotated.
  • a preferred embodiment of the invention is characterized in that the support fingers, starting from a central longitudinal plane of the support column, extend obliquely downwards or are chamfered at the front ends. Then the spacer elements can then also be applied by horizontal and then vertical movement, with dirt particles lying on the storage surface being pushed off. Since the spacer elements are at least partially pushed over the supports while touching the material, it is advisable to provide the supports with a wear plate.
  • the support fingers can have stops to limit a relative horizontal movement between support fingers and spacer elements.
  • a pit with vertical guides can be arranged below the lower carriage, which guides correspond to the guides on the lower carriage and are arranged such that the support column can be lowered into the pit in a position remote from the deck press.
  • a multi-daylight press 1 of conventional design which has a plurality of levels 2, optionally designed as heating plates.
  • the levels 2 have protruding claws 3 on the end face as supports for plate-shaped spacer elements 4.
  • the spacer elements 4 have centering pins 5 which engage in the associated centering holes 42 in the claws 3 (FIGS. 4 and 5).
  • This device initially consists of a support structure 6 for horizontal rails 7 arranged above the top floor 2, on which rollers 8 a carriage 9 can be moved.
  • the carriage 9 essentially consists only of a frame-like frame, to which a piston rod 10 of a lifting cylinder 11 is connected, which in turn is supported on the supporting frame 6.
  • the lifting cylinder 11 By actuating the lifting cylinder 11, the carriage 9 can be moved towards and away from the multi-daylight press 1 in the horizontal direction.
  • a motor 12 with a gear 13 as a drive for a cable winch 14 is arranged on the carriage 9.
  • the end of the cable wound on the cable winch 14 is attached to the carriage 9 or to a part connected thereto in such a way that a cable loop is formed in which a deflection roller 15 is guided, which is held in a fork-shaped bearing 16.
  • the bearing 16 is arranged rotatably at the end of a vertical support column 17 about the longitudinal axis 18 of this support column 17.
  • the support column 17 has at its upper end, which supports the bearing 16, a conical section 19 which serves as a centering section for inserting the support column into a centering bush 20 fastened to the carriage 9 (FIG. 1 c).
  • a further motor 21 with a vertical axis of rotation is arranged on the carriage 9, to which a gear 22 is assigned which has a pinion 23 which meshes with a gearwheel 24 fastened to the support column 17 in the position shown in FIG. 1c.
  • the support column 17 is rotated about its longitudinal axis 18.
  • the support column 17 has, over its length, a number of support fingers 25, 26 corresponding to the number of levels 2.
  • the support fingers 25, 26 of each level extend parallel to one another and are at a distance which is slightly less than the corresponding dimension of the spacer elements 4.
  • horizontal rails 43 are in turn arranged for a carriage 28 movable thereon with rollers 27, which together with a lifting cylinder 29 and in the same direction as the carriage 9 in horizontal direction is movable.
  • the lower end of the support column 17 merges into a pin 30 on which a bushing 32 is rotatably mounted with roller bearings 31 and carries two guide tabs 33 which extend diametrically opposite one another radially and vertically (FIG. 1 c).
  • the guide lugs 33 engage in associated U-shaped guide profiles 34 on the inside of the carriage 28.
  • the support column 17 has possibly interrupted guide lugs 35 along their entire length, the arrangement and function of which corresponds to the guide lugs 33 on the bush 32.
  • the support column 17 can be lowered by releasing the cable winch 14 with vertical guidance. This is indicated in Fig. 1 c with dash-dotted lines.
  • the support column 17 hangs on the rope 37.
  • the device shown works as follows: In the lowered position shown in FIG. 1b, spacer elements 4 are placed on the supporting fingers 25, 26 of the support column 17, the support column being optionally raised step by step by actuating the drive 12. In order to prevent the spacer elements from slipping on the supporting fingers 25, 26, the supporting fingers 25, 26 have protruding pins 39 which engage in assigned openings in the spacer plates.
  • the support column is drawn with its upper conical section 19 into the centering bushing 20 on the upper carriage 9, with the guide tabs 33 of the rotatable bushing 32 at the lower end at the same time engage the support column in the U-shaped guide profile 34 of the carriage 28 (Fig. 1 c).
  • Spacer elements 4 which are to be replaced are located in the multi-daylight press 1.
  • the support column 17 is moved by actuating the lifting cylinders 11 and 29 in the direction of the claws 3 of the multi-daylight press 1 until the free ends of the support fingers 25, 26 underlie the associated spacer elements 4 resting on the claws 3.
  • the support column 17 is then raised a short distance by actuating the motor 12 and moved out of the press area by actuating the lifting cylinders 11 and 29.
  • the support column 17 can now be rotated by 180 ° by actuating the motor 21, so that the spacer elements no longer required are pivoted out of the area of the multi-daylight press and the new spacer elements are pivoted to the associated supports of the claws 3.
  • the support column 17 is lowered again, so that the new spacer elements 4 are placed on their supports or pushed onto them, their centering pins 5 engaging in the associated centering openings of the supports.
  • the support column 17 is then moved away from the area of the multi-daylight press 1 by actuating the lifting cylinders 11 and 26.
  • the multi-daylight press is now ready for use again.
  • the supporting fingers 25 and 26 are slanted relative to the horizontal.
  • the spacer elements 4 are also transported in an inclined position and pushed onto the claws 3, which are provided with a wear pad 40. This is done in the illustrated embodiment exclusively by horizontal movement of the support column 17 with the beveled support finders 25 and 26 connected to it. It can be seen that in the arrangement shown in FIG Spacer 4 initially rests on one side on the wear support 40 and is displaced by the support fingers 25, 26, if necessary with a stop 41, in the direction of the floor, the spacer plate sliding over the wear plate 40 with one edge.
  • the support column 17 is lowered with the support fingers 25, 26 and the spacer 4 is placed on a wear plate 40 serving as a support, the centering pins 5 engaging in assigned centering openings 42 and aligning the spacer 4.
