large, and the entire system is complex and expensive, retrieval can be useful for larger systems. the

especially for medium and small services. actual advantages of the invention are derived therefrom

In order to avoid these disadvantages and not to affect it.

According to the invention, it is further proposed to reduce the costs considerably, according to FIG. that with one and the same device automatically by a sequential circuit after the end of the closing of each function assigned to the floor space takes place,
zelkastenförderstückes mit dem Vollgutkastenzuför- It is also the subject of the invention that those and the other end of the single box conveyor io a complete box layer having adjusting piece connected to the empty box conveyor in the direction of the one on the front side that is leading into the device Pallet conveyor has a single box conveyor as empty pallet feeders and the pallet conveyor, which continues out of the device step by step by one box dimension, is a longitudinal conveyor that moves full pallets and the individual conveyor is designed and the conveying direction of 15 box conveyors, a transverse pusher and cross pusher head against the storage area both the changing transverse pusher for intermittent pushing over in the sense of unloading and in the sense of loading a full load of pallets fed one behind the other in a row is assigned alternately to switch and bottle crates and that both conveyors are controllable in such a way that each of the empty boxes can only be switched on alternately. With this unloaded pallet, the conveyor can be reversed and loaded with full crates immediately afterwards. With such a conveying device for the purpose of splitting or adding devices, both manual palletizing and the compilation of a layer can be ensured. Out of palletizing. The individual specially provided for this, of course, the gripper elements of the conveying devices only have to be switched over to the gripper head when depalletizing during the process. The space required is hardly greater than with 25 runs for requesting and when palletizing, each individual is only in the gripping position for depalletizing or at the end of the return. This device used for palletizing. In addition, there is no difference between each one but only one empty pallet magazine, but also an empty depalletizing and palletizing device.
According to the invention, it is further proposed that the palletizing machine be saved. As soon as a pallet loaded with empty 3 ° as a longitudinal conveyor and cross slide elements is emptied, the conveyor direction is sensigly drivable rods are arranged, with the reverse for this pallet and this pallet vveils the non-driven rod in its end! - over the Full crate feeder again loaded with full as a stop for the crates from the other conveyor. The Lecrgutkasicnabförderer is used for moving boxes. In addition, the position is blocked. Correspondingly, the full product surface is on driven rollers, which however only block the case feeder when depalletized and convey towards the pallet when palletized, therefore on the empty case discharge conveyor empty goods- When depalletizing, the longitudinal conveyor rod is conveyed away into the case. Instead of two opposite directions, palletizing machines of different radio widths separated by boxes are always moved further, with the rolling of the floor space being, according to the invention, only a 40 still standstill.

Device available, both for depalletizing and according to the invention is further proposed

is also set up for palletizing and this that the single box conveyor piece of the device both

Performs function alternately. on the side of the full crate conveyor as well

According to the invention it is further proposed that an Arredaß be installed on the side of the empty container conveyor which has 45 animal device on the single box conveyor part of the device. As a locking device Connected box feeder and discharge conveyor can each use levers or the rollers of the conveyors Have storage capacity that is at least the track used when their drive is still-one and a half times the number that is placed on a pallet.

stackable boxes. According to the invention it is further proposed that the downstream 50 that dns Einzelkastenfördei piece in the direction of or upstream machines, namely the Ein Leergutkastenabförderer has drivable rollers, and unpacking machines, is usually anyway always met, so that the discontinuous or alternating only driven in the same direction. The wise work of the device has no influence whatsoever on both the full product continuity entering the machine, the atbüita mode of the downstream or upstream boxes, and the machines that have come out of the machine. Only when the empties boxes are on and they all move in one drive of the entire system, i.e. when filling the direction, but with the conveyed full container transport systems, some empty pallet boxes must initially be locked inside the device and taken out of the machine at right angles, z . B. be pushed over to the infeed on the floor space, so the then not yet occupied Vollug- 60 that so the full goods boxes that have arrived the device pallet conveyor. The pallets set aside are not left on the single box conveyor, as is the case at the end of work or in between, this is provided for the empty boxes.
if an equalization should be necessary, again. According to the invention, it is further proposed to insert. The handling is possible with medium and that between the front side of the floor space and the lower performance without impairment 65 single box conveyor piece at least one alternately and is not at all significant compared to the reduced total effort depending on the device function. An automatic conveyor roller is also arranged. This reversible conveyor intermediate storage of such empty pallets with roller serves to bridge the gap both during

The device consists of the housing 1 and the pallet roller conveyor 2, which is suppressed on the single box conveyor section 10 and which is connected to an empty pallet 15. The empty boxes are labeled 25, feed conveyor la and a Vollgutpalettenabförderer they leave on the empty box conveyor 13 is connected to lh. In the interior of the housing 1, the housing 1 or the single box conveyor 10. the path 2 has an interruption in which the uppermost pallet lifting table 3 is being moved in a known manner, for example by means of box layer 6 through the gripper elements la of the chain transmission 3 (j, can be moved up and down. 20 layer gripper head 7 detected. The entire empties - The pallet 4 box layer located on the pallet lifting table 3 is in the direction of arrow 8 on which in Fig. 1 still carries a load of 3X9 boxes . Floor 9 implemented and parked there. When the pallet lift table 3 is still in the direction of the stationary rollers 9 ', the boxes are lifted by the arrow 5, so that finally the top bar conveyor 9 /) in the direction of the arrow 24 by each box layer 6 detected by the gripper elements la of 25 a box length or box width forward conveying layer gripper 7, held and changed in the sense, so that initially the first row of S chicht 6 "of the arrow 8 on a fixed, unchangeable, hooked arrives on the roller 11 and implemented by this in the sense of the shaped path and compieü on the adjusting arrow 11" circumferential roller from the rear surface 9 with conveyor rollers 9a and circumferential rod Rows of boxes of layer 6a separated and aut the conveyor 9b can be deposited. In this case, the 30 single box conveyor piece 10 is transferred. The drive of the layer gripper head 7 as desired. The transverse slide 15 of the single box conveyor 10 can then be slid and lifted on a carriage, locked in its initial position and is used as or at the end of lever arms on the stop for each of which is guided onto the single box conveyor track 8. Between the footprint 9 pieces transported boxes. On this, the and the 35 boxes arranged within the housing 1 in the conveying direction of the arrow 14r (Fig. 2 and?) Single box conveyor piece 10 is provided an intermediate roller 11 that can be reversed and, if the lock 16 is ineffective, but can be driven by a lock /? stopped supply of full boxes 23 as an intermediate space between the floor space 9 and the empty boxes 25 on the empty box conveyor of which 10 bridged and the 13 boxes located on it in the direction of arrow 14 b in series one behind the other conveyed a conveying pulse in the respective conveyor 40. These empty boxes 25 are then given direction. In addition, the intermediate, as usual, takes over to the unpacker, in which the dirty item roll 11 also removes the separation of the bottles from the crates during depalletization and moves the individual crate rows to a layer 6 '. To continue treatment. The refilled conveyor track section 10 is on the input side of the full goods and closed bottles then go to the single-box feeder 12 and on the output side the empties 45 packer and are inserted into the boxes, kastenabfördercr 13 connected, which then arrive in these full-goods boxes 23 in the full direction of the arrows 14a, 14 may be driven b kön- gutkastenzuförderer 12 to the housing 1 or to NEN. The single box conveyor piece 10 also has only single box conveyor piece 10, the rollers driven for loading and unloading in the direction of arrow 14c. charger leads.

A transverse slide 15. hydraulically operated or as 50 In Fig. 4b is a phase of the further course

they are totally discharged. The unloaded pallet 4 the single box conveyor 10 and against the Ar

will hit 16 again after switching the conveyors. The i

loaded with full crates and on the full pallet emptied from the previous working period

still in their uppermost position, as shown in FIG. 5 a shows. The Vollgutkästen 23 is now located on the single box conveying pieces 10 are by the pusher 15 26 initially aut in the direction of the arrow in the direction of arrow 11 b rotating intermediate roll 11 and conveys it onto the driven in the direction of the arrow 17 feed rollers 9a of the footprint. 9 The full goods boxes 23 are therefore moved in rows against the rod of the rod conveyor 9 b , which is located as a stop in the end position as a stop, and accumulated there until a complete layer of full goods boxes 23 is pushed over three times by the transverse pusher 15 and the intermediate roller 11 on the shelf 9 is formed, which is grasped by the gripper elements Ta of the layer gripper head 7 and placed on the empty pallet 4 in the direction of arrow 8a. The pallet lifting table 3 is then just lowered by the height of a box layer, and the next complete layer, which has accumulated on the floor space 9, can be translated in the same way and placed on the top layer 6 until the pallet is fully loaded and settled is also again in the lowest position at the level of the pallet roller conveyor 2. The fully loaded full pallet 22 then leaves as shown in FIG. 2 and 3 on the full pallet conveyor Ib the device. Now the device can be switched back to depalletizing (Fig. 4a, 4b), which can be done automatically by sequential switching or manually. However, the individual processes are programmed and then run automatically in sequence. So there is again an empty pallet 21 placed in the housing 1 and completely

ίο depalletized, with the individual boxes then on the empty box conveyor 13 are continued.

If the teaching of the invention is followed and have Vollgutkastenzuförderer 12 and empty crate conveyor 13 or their storage capacities of more than

is about one and a half times the number of on one Pallet stackable boxes, then each de; last empty crate not yet in the unpacker If the empties boxes 25 are already being re-supplied, the palletizing device still arrives has meanwhile loaded a full pallet with full container boxes 23. The same applies accordingly alternating for the packer, the intermediate storage on the full crate conveyor and the palletizing function in one and the same device.
