Definitions

  • the invention relates to a stacking device for rod-shaped or board-shaped piece goods, with vertically movable stacking trolleys on stands with horizontally movable support arms and with fixed stops, parallel, circumferential drivers that receive the piece goods on the back of the stand and on one on the top of the Place the shelf on the stand.
  • Stacking devices of this type are known from German patents 1 191 296, 1 235 808, 2 445 536 and 2 553 724.
  • the piece goods transported vertically upwards by a carrier on the back of the stands are individually deposited on the storage surface located on the top of the stands and taken away by the following driver by means of its fixed stop for further transport.
  • the general cargo is transported on the front of the stand.
  • the individual piece goods are conveyed downwards until they are placed on the extended support arms of the stacking trolleys and individually moved onto them to form a stacking row.
  • the support arms are moved back and the stacking trolleys are moved vertically by the height of one row of stacks, whereupon the support arms are extended again to form the next row of stacks.
  • the invention is based on the object to provide a stacking device of the type mentioned, in which the rotational speed of the driver largely independent of the change of position can be set and thus increased compared to conventional stacking devices, in which the risk of jamming of the driver is avoided when going down and at which a lower overall height is possible.
  • the invention provides that the length of the storage area corresponds to the width of a stack row to be formed, that the stored piece goods are pushed together by means of the fixed stops on the storage area to form a stack row, the fixed stops being guided so that they are at the beginning of the Immerse the storage surface in the stands, and that the stacking trolleys with retracted support arms that protrude above their top edge can be moved vertically under the storage surface to remove the stacking row and can be lowered with the stacking row after the support arms have been extended in order to set the stacking row down by pulling in the support arms.
  • the rotational speed of the drivers is essentially independent of the time required for a change of position, since in the stacking device according to the invention the stack row is formed in parallel with the change of position.
  • the stacking row is formed on the storage surface at least the width of a stacking row on the top of the stand, onto which the individually conveyed piece goods are conveyed one after the other by means of the fixed stops of the drivers.
  • Each fixed stop of each driver is immersed in the interior of the stand at the same place on the storage surface, so that the rear edge of each board or the like to be placed comes to rest in the same place.
  • each newly arrived board pushes the boards in front by one board width on the shelf to form the desired stack row.
  • the finished stack row is lifted immediately after pushing on the last board of the stack row from the retracted support arm of the vertically moved stacking trolley and removed from the storage surface by extending the support arm and lowering the stacking trolley, on which a new stack row can be formed immediately after the stack row has been lifted .
  • the previous stack row is placed on the desired stack, so that there is no loss of time for the change of layers.
  • the fixed stops can be arranged on one side at the front end or in the middle area of the drivers, so that the board placed on the storage surface by a driver is only pushed into the desired stack row by the next driver.
  • the fixed stops can also be arranged at the rear end of the driver. As a result, each fixed stop pushes the board conveyed by the associated driver directly into the stack row.
  • each driver is connected to one link of the two chains guided in parallel by means of rotary pieces which are rotatably but laterally fixed in the driver and are rigidly connected to both bolts of the respective chain link. This results in greater strength in the connection of the drivers with the associated chains.
  • the rotating pieces are rotated within the drivers, so that the drivers always remain with their upper surface in a substantially horizontal position.
  • a retaining device is arranged on each of the stacking trolleys for pulling back the support arms when depositing a row of stacks. Furthermore, photocells are provided to control the stacking trolleys depending on the upper edge of the last stack row and number of pieces - as well as the layer counter.
  • a stacking device for rod-shaped or board-shaped piece goods regularly comprises at least two stands 1, which are displaceably arranged on a frame frame 2 at a distance from one another.
  • the stacking device has the task of neatly stacking the boards 4 (or other rod-shaped or board-shaped piece goods) arriving on the rear side 3 from feed devices, not shown, on the front side 5 in a stack 6 on a pallet 7.
  • the stand 1 has in its interior two revolving chains 8, 9 which are offset in the longitudinal direction of the stand 1 and are arranged parallel to one another in the transverse direction, as can be seen from FIGS. 1 and 2.
  • the chains 8, 9 are driven in the direction of the arrow 10 by drives (not shown) and run around chain wheels 11 arranged in corner points. Between the chains 8, 9 arranged parallel to one another, drivers 12 with fixed stops 13 are arranged in the manner described below, which run together with the chains 8, 9 in the direction of arrow 10.
  • Each driver 12 conveys a board 4 on the back 3 of the stand 1 upwards onto the top of the stand 1 designed as a storage surface 14.
  • the storage surface 14 extends at least by the width 15 of a stack row 16 to be formed over that of the fixed stop 13 of each driver 12 on the upper side of the stand 1.
  • the storage surface 14 is formed by the top of the stand 1 and can be implemented by a corresponding slide rail.
  • the distance traversed by the fixed stop 13 on the upper side of the stand 1 is precisely limited by the beginning of the downward movement of the drivers along the chains 8, 9 according to the arrow 17. If adjustable fixed stops 13 are provided on the drivers 12 in a manner not shown, then the immersion time of the fixed stops 13 in the surface of the storage surface 14 can be changed.
  • the boards 4 are conveyed by means of the drivers 12 onto the storage surface 14, deposited there and only pushed from the fixed stop 13 of the subsequent driver 12 into the desired row of stacks 16.
  • the stand 1 is given a width which is approximately 1.5 times the width of the chain drive 8, 9. If necessary, the back 3 of the stand 1 can correspond to the dashed line beveled so that the drivers 12 are guided along the bevelled rear side 3. Correspondingly, the front side 5 can be moved inwards below the abiagefiiche 14.
  • the stacking carriages 18 guided on slide guides of the stand 1 are driven by means of drives (not shown in detail) with the support arms 19 protruding beyond the upper edge of the stacking carriage 18 for lifting the stack row 16 below the storage surface 14 move vertically and lowered with the stack row 14 after the extension of the support arms 19 onto the stack 6 in order to deposit the stack row 16 here by pulling in the support arms 19.
  • the support arms 19 then move again in the vertical direction to remove the new stack row that has been formed in the meantime.
  • Retaining devices 20 for the stack row 16 to be placed on the support arms 19 can be arranged on the stacking carriage 18.
  • the retention device 20 can be designed as a pawl, simple locking lever or the like.
  • the front side 5 of the stand 1 can also serve as a retainer.
  • FIG. 3 shows a stacking cycle.
  • a new stack row is just being formed while the stacking carriage 18 has put down the previous stack row.
  • the new stack row 16 is finished, the stacking carriage 18 has moved vertically.
  • the new stack row is being lifted.
  • the stack row 16 is extended onto the support arm 19 and is lowered and set down in FIG. 3e, while in FIG. 3f the next stack row is formed again.
  • 4ff shows a preferred embodiment of a connection between the drivers 12 and the associated chains 8, 9.
  • the driver 12 is each connected to a link 21, 22 of both parallel chains 8 and 9 via a rotating piece 23, 24, which is rotatable in the driver 12 and laterally by, circlips immovably and with two bolts 25, 26 or 27, 28 of the respective chain link 21 or 22 is rigidly connected.
  • This form of training ensures a secure, articulated connection between chain 8, 9 and driver 12. If a chain link 21, 22 of a chain 8 or 9 is deflected around a sprocket 11, the rotating piece 23, 24 can rotate in the driver 12 without being laterally displaced. The drivers 12 consequently remain in the desired horizontal position.
  • FIG 4 shows an alternative embodiment of a driver 12 with a fixed stop 13 arranged at the rear end.
  • Photocells 29 or components having a similar function can be arranged on the stacking carriage 18 and, together with an electronic control device (not shown in more detail), control the lowering of the stacking carriage 18 as a function of the height of the upper edge of the previously stacked row 16.
  • Electronic number counters 30 can be attached to count the number of pieces per stack row 16.
  • 16 layer counters 31 can be attached in the area of the stack rows being lowered.
  • the stack row 16 formed on the storage surface 14 can also be pushed onto the already extended support arm 19 in an alternative mode of operation of the stacking device.
  • a stacking carriage 18 with a support arm 19 can be arranged on both sides of each stand 1, which alternately convey a stack row 16 downwards.
  • the front wall 5 of the stand 1 can serve as a retainer.
  • a stand 1 ' is shown with its front side 5' with dashed lines, which is narrower by the distance of the front side 5 of a stand 1 from the front side 5 '.
  • the stand 1 ' is provided with a rigid cantilever arm 32 which projects beyond the front 5' and whose surface extends in the same plane with and in an extension of the top of the stand 1 '.
  • a stack row 16 is thus at least partially pre-formed on the cantilever arm 32.
  • the stack row 16 is removed by means of the vertically movable stacking carriage 18 with support arms 19 in the manner described above.
