Description

Device for stacking piece or bagged goods on pallets

The innovation relates to a device for stacking piece or bagged goods on pallets and in particular for stacking sacks, ζ. Β. Cement sacks.

There are already a number of palletizers known to load pallets by means of powered roller conveyors, conveyor belts and the like. the Pallets are introduced individually into the palletizing area and the bags to be stacked become partial stored in the position in which they are conveyed, but another part must be rotated and then lies at right angles to the first-mentioned sacks.

The known palletizing devices have the disadvantage that they have a relatively high energy consumption, that with them the goods to be loaded can easily be damaged or deformed and further that their Loading speed for the stacking of large quantities is not high enough, so sometimes several devices must be used side by side.

It is now the task of the innovation, a device for stacking piece or bagged goods on pallets and in particular a device for stacking sacks

To create pallets in which the disadvantages mentioned no longer occur and which allow it to be reduced Energy consumption to make a particularly fast and reliable palletizing without the need to be palletized Goods are damaged or deformed, so that particularly good stacking in cross bracing is achieved.

The device according to the innovation should continue to be wear-free and fully automatic over a longer period of time can work. It should be produced in a known manner stacks of goods in which the goods lie with their longitudinal extent in part at a right angle to one another.

This object is achieved according to the invention in that the device has a feed track for the goods, a rotating device, a deflecting device that simultaneously stores the goods of the same length, a transport and smoothing track, a depositing trolley arranged in the palletizing area and an automatic pallet feed for the empty pallets In another embodiment of the stacking device, the deflecting device can be operationally in front of the rotating device are located.

For storing incoming goods and thus for setting a particularly high stacking speed, the device is advantageously designed such that the Deflection device contains a roller grate with individual rollers, the tendency of which indicates a stop and which can be lowered under a roller conveyor, its roles

run at right angles to the rollers of the roller grate.

The storage results in the compilation of the part of the goods to be palletized of the same length, and since the deposit on the pallet stack during the

Entire process requires the greatest amount of time, this previous compilation makes it a special one great time savings achieved. In doing so, the

Use of the inclined roller grate reliably prevents deformation even of easily deformable bags without reducing the drainage and depositing speed.

Since thrust plates and the like, the operation of which is prone to failure, are not present and the existing ones Funding only carry out minor strokes, is a smooth operation of the device is ensured.

In view of the advantages that can be achieved through the subject of the innovation, an optimal solution of the upcoming Problems are talked about. 15th

In the following, an embodiment of the innovation is described in more detail with reference to drawings. Show it;

Figures 3 and 4

FIG. 8 shows a plan view of the automatic pallet feed. The innovation according to the device for stacking pieces or Bagged goods on pallets, especially for stacking

of sacks, consists according to Figure 1 of operationally interconnected stations. It is a feed track 1 for the goods,

which is denoted by 7, which is followed by a rotating device 2, which via transfer rollers 15 a deflection device 3 is charged, in which the pallet layers are already partially assembled can, which is followed by a transport and smoothing path 10 with driven upper and lower rollers, which automatically forwards the sacks to the trolley. The Äfolegewagen on which one layer is complete is accumulated, consists according to the innovation of a roller grate and is used to store the accumulated goods pulled out onto the pallet under these goods.

The sacks run from the feed track in the longitudinal direction on dx <2 rotating device 2, which is designed as follows is:

A turnstile 17 is arranged between the incoming and outgoing means of transport. It contains cutouts for receiving driven or non-driven rollers 16 or equivalent devices and enables turning movements after lifting the turnstile

f or turntable 17 and / or after lowering the in the turntable

| ^; richly arranged conveyor or rollers 17.

25 in the turnstile or turntable 17 is in the top Partly hollow shaft 18, 22 arranged with segmental recesses in the center of a roller.

The rotation of the goods 7 takes place after the feeding means of transport this into the correct position via the Have brought the turning device and lifted the turnstile or lowered the rollers located in the turning area have been. After the rotation, the turnstile and / or the rollers return to their original position and that "° rotated goods are removed from the turning area.

Via the transfer rollers 15, which can be driven or not driven, the material to be conveyed then arrives at the deflection device 3, in which it runs along the roller grate 11 in a slightly inclined position up to the stop. The roller grate 11 is raised above the roller conveyor 12 and is held in this position by a pivot lever by a piston-cylinder unit. The outer end rests on a track and is displaceable on this by means of a roller.

After running in and saving part of the zu The roller grate 11 is lowered into the position according to FIG. 4 for palletizing goods. That to be promoted Well now rests on the roller conveyor 12, the one on your side with a slight incline towards the palletizing area is inclined and the good then runs at right angles to its previous direction of movement from the steering device 3.

The deflection device 3 is followed by a smoothing station IO, which is arranged above and below, having transverse driven rollers.

The goods to be palletized then run up according to FIG

a storage trolley, which in turn has individual roller tracks, after a complete layer has been collected on the trolley 4 this is shown in Figure 2 in the direction of its roles from under the accumulated layer

^ow pulled and the goods to be palletized, which are held by a stop 8, lower themselves onto the pallet or onto the topmost layer already on the pallet. The pallet is then lowered again by the height of one layer and the depositing carriage 4 is again

retracted to pick up the next goods.

It has surprisingly turned out to the expert that even for cement sacks there is a tendency to the mentioned

I · · ■ ■ »■

Roller conveyors of 4% is sufficient. When processing packages and the like, even angles of inclination of 2% are sufficient and it can therefore be seen that the strokes to be applied are only small and therefore a simple construction of the modernization device is given, with the lack of thrust plates and the energy to be expended only low is. In particular, the roller grids or roller tracks are advantageous because of the low rolling friction compared to the static friction when using metal sheets from earlier designs.

According to FIG. 8, the pallet feed 5 is constructed as follows

The pallet feeder 5 consists of two opposite one another Walls of the Palettenmagaains housed movable frame 23 each with four guide rollers 19 and attached to the lower horizontal of this frame grippers 24 and two track systems in which the guide rollers 19 run.

The upper guide rollers 19 run in the vertical part of the track systems to and fro .. The lower guide rollers 19 run in two for up and down movement ² ^ separate track curves 9, each of which has a shunt 21 to the upper intersection of the curves. As a result, the lower guide roller 19 is guided in different ways during the upward and downward movement. If the lifting device is in the lower end position, then the lower guide rollers 19 are in a lateral position at the lower intersection of the two opposing curves. The grippers 24 have been pulled out of the pallet stack.

When the lifting device moves upwards, the lower guide rollers 19 in the curve 9 first become vertical upwards and then sideways / so that the grippers 24 grip the second pallet from below. In the upper The end position of the lifting device is the pallet stack from

lifted from the bottom pallet. During this upward movement the lower guide roller 19 has the switch 21 cashed.

In the meantime, the relieved bottom pallet is transported to the loading point and the lifting device begins its way back down. Here, thanks to the switch 21, the lower guide rollers 19 are first guided vertically again until the pallet stack is deposited again. Then the curve 9 leads the lower guide rollers back into the lower end position, whereby the grippers 24 are pulled out of the now lowermost pallet.

This entire process is repeated until the pallet magazine is emptied, whereupon a new stack is inserted will.
