Definitions

  • Devices of this type are usually used in the manufacture of can frames in order to insert rectangularly cut boards into a device for rounding the boards. This must be done with short cycle times on the order of 0.1 to 0.2 seconds, for example, and with great accuracy.
  • a device of the type mentioned in which the bottom board of a stack held between vertical stack guides on its underside by one or in each working cycle several suction cups attached to a carrier is detected.
  • the carrier is connected by a parallelogram to a stationary frame in such a way that it can be moved parallel to itself in an arc that only leads vertically downwards and gradually transitions into a horizontal direction of movement. With each such movement, a board is placed on a pair of parallel guide rails that are arranged horizontally below the stack guide. A slide can be moved back and forth along the guide rails, on which pairs of pawls are arranged to take one board with them.
  • DE-B-1251 230 Another device of the type mentioned is known from DE-B-1251 230.
  • the stacking of boards can also be done upwards.
  • US-A-3409149 a further device of the type described in the opening paragraph is known, in which in each working cycle the uppermost board of a stack is gripped by a plurality of suction cups which are suspended on rods which extend from a frame-like support between magnetic rollers extend below.
  • the carrier hangs on parallelogram links and is movable upwards in such a way that the circuit board gripped by the suction cups is raised into a position in which it rests on belts which wrap around the magnetic rollers. In this position, the circuit board is released and fed horizontally by the belts to a pair of rollers which grips the circuit board and conveys it further.
  • the removal of the boards from the stack is a first operation and the transfer of the boards to the pair of conveying members, from which the boards are gripped on both sides, is a second operation, which is separate from the first.
  • the present invention is based on the knowledge that this separation is the cause of vibrations of the boards, which occur in the known devices and can reduce the frequency and the accuracy of the board movements from the stack to the conveying members.
  • the invention is therefore based on the object of designing a device for unstacking and conveying boards, in particular blanks for tin frames made of sheet metal, in such a way that the boards can be fed quickly, largely free of vibrations and precisely to the conveying members provided for the further conveying of the boards.
  • the carrier is movable on a path which, starting from the stack, extends transversely to the plane of the board, then merges in a direction leading at least approximately parallel to the plane of the board to the pair of conveying members and finally runs across the board level again.
  • the device shown is intended for unstacking and conveying boards 10, which are kept in the form of a stack 12 between vertical stack guides 14.
  • the stack guides 14 are connected to one another in pairs by edge strips 16, each of which has an inwardly projecting projection 18 on which the bottom board 10 rests.
  • two parallel vertical plates 20 are arranged, only one of which is shown.
  • a serpentine groove is machined, which forms a guide curve 22 and has three vertical sections 24, 26 and 28 and intermediate horizontal sections 30 and 32.
  • Each of the sections 24 to 32 mentioned can be as short as desired and, in extreme cases, only be formed by a turning point between successive circular arc sections, preferably quarter circular arcs.
  • the guide curves 22 can, for example, be milled into the two plates 20 with a end mill and have such a width that in each of the two guide curves 22 two cam followers 34 and 36 can be moved up and down without jamming, but also with almost no play.
  • the cam followers 34 and 36 are rollers in the example shown, which are mounted in pairs on a carrier 38.
  • the carrier 38 is connected by a ball joint 40 to one end of the connecting rod 42, which is length-adjustable in the manner of a turnbuckle.
  • the other end of the Connecting rod 42 is connected by a further ball joint 44 to a crank 46 which is fastened on the shaft 48 of a rotary motor 50.
  • the rotary motor 50 has a housing 52 in which the shaft 48 is mounted and a rotary vane 54 fastened thereon can be rotated back and forth between adjustable stops 56 and 58.
  • the rotary motor 50 is of a commercially available type and can be driven with a pressurized fluid, preferably compressed air, which is fed to it via adjustable throttles. The distance and the speed at which the carrier 38 can be moved up and down along the guide curves 22 can thus be adjusted.
  • the plates 20 are arranged on a cross slide arrangement 60, likewise of a conventional type, which is only indicated in FIG.
  • a vertical column 62 is attached to the carrier 38 and carries a yoke 64.
  • Several, for example two, adhesive bodies 66 are fastened to the yoke 64, which in the example shown are formed by suction cups and can be placed on the underside of the lowermost board 10.
  • a pair of conveyor members 68 and 70 Arranged below the pair of stacking guides 14 on the right in the drawings is a pair of conveyor members 68 and 70, which in the example shown are formed by horizontal rollers and are intended to grasp each individual board 10 on both sides, that is to say above and below, and to feed it to a device , from which they are rounded in order to be subsequently welded into cylindrical can frames.
  • the plane in which the shaft 48 of the rotary motor 50 lies is shown pivoted out of the plane of the drawing by 90 ° for the sake of clarity.
  • the shaft 48 extends at right angles to a tangential plane which touches the guide curves 22 and is inclined at 45 ° with respect to the board plane which is horizontal in the example shown.
  • the connecting rod 42 is always at least approximately in this tangential plane.
  • Fig. 3 shows the device at the beginning of a work cycle.
  • the rotary motor 50 and thus also the carrier 38, assumes an end position which is defined by the adjustable stop 58. In this end position, the adhesive bodies 66 grip the lowermost board 10 in the stack 12.
  • the rotary motor is then switched on, so that the carrier 38 is pulled obliquely downwards by the connecting rod 38.
  • the cam followers 34 and 36 roll in the serpentine guide grooves 22 simultaneously in exactly the same direction, so that the carrier 38 is guided without canting and the board 10 sucked in by the adhesive bodies 66 remains parallel, in the example shown horizontal.
  • the carrier 38 After rotation of the shaft 48 by approximately 110 ° to 120 °, the carrier 38 has reached the position according to FIG. 4, in which the right edge of the plate 10 in FIGS. 3 to 5 has penetrated between the conveying members 68 and 70 and from this is recorded. Now the adhesive bodies 66 release the circuit board 10. This can be done in that a vacuum previously applied to the adhesive bodies 66 is released or even replaced by an air blast. However, if the adhesive bodies 66 are electromagnets, these are reversed.
  • the rotary motor 50 continues to move until its rotary wing 54 abuts against the adjustable stop 56.
  • the carrier 38 reaches its end position shown in FIG. 5.
  • the direction of movement of the rotary motor 50 is reversed, so that the carrier 38 returns to its starting position according to FIG. 3.
  • rotary motor 50 instead of the rotary motor 50 shown, another drive means can be provided for the carrier 38, for example a pneumatic piston-cylinder unit.
