Device for loading, conveying, sorting and stacking materials such as metal sheets, tournaments, Kanatstoff, cardboard and flatten of every kind

The invention relates to a device for Loading, conveying, sorting and stacking of materials, like ».B. Sheets, veneers, lunetatoff poles, cardboard or the like. Ton a stack or conveyor, where dm Material is lifted and held against the conveyor by a negative pressure

There are ready devices known at which the material is lifted with a suction cup from Stack is withdrawn and transferred to a conveyor, However, this device grinds the captured material About the next sheet, which is especially important for finished surfaces or veneers is not advantageous because the existing static friction affects the surface can damage.

Furthermore, devices are known in which A suction bell is arranged over the stack, next to which conveyors are running, whereby the suction cup is held against the conveyance by the material »This Saugglooke is only suitable for the promotion of flat udders, whereby the Besohioken the Saugglooke has an additional and downward movement and separately controlled mechanical aids are required for sorting and stacking.

Oeaäfl the invention, the device has a or several hollow tubes which can be brought under negative pressure, are open at the bottom and to which a suction tube or several suction tubes are connected, next to or below each Hollow one or more conveying means such as belts, binders, chains or rollers or the like are provided which ■ run around for sale on oil surfaces and the undersides about «lower than the lower edges of the hollow rail, so the conveyed material itself acts as a valve and sussjuMo «it the hollow rails as the wall of the sioh

lengthening / Jaugrohres serves. The negative pressure is from any device, preferably an exhaustor generated, with of course negative pressure and air volume the extent and weight of the material to be conveyed need to be adjusted.

^ Xn Jer drawing, embodiments of the invention are shown schematically u.zw. shows Fig. in view and Pig. 2 from the side in the direction of arrow A a device for loading and conveying sheet-like material, Figs. 3 and 4 in the same representation the device for sorting according to the length or width of the material and Fig. The device as a stacking device »

According to FIGS. 1 and 2, 1 denotes a hollow rail, open at the bottom, made, for example, of a U-profile, to which a suction pipe 2 is connected, which of a Exhaustor, not shown, receives a negative pressure via line 3. Both sides next to the hollow rail 1 are arranged along these two conveying means, e.g. endlessly revolving belts 5, the underside of which is somewhat lower than the underside of the hollow rail 1. At the end of the funding 5 there is another funding under this, e.g. «arranged in conveyor belt 6. The hollow rail 1 has in the middle of the mouth of the suction tube 2 on a partition 4, under which the stack of material 7 on a

Lifting platform 8 is located, which is arranged in front of the suction pipe 2.

On the hollow soft rail 1 there are sliding guides 9 for the gills 5 intended. Depending on the width of the material 7, two or iaehrere hollow rails 1 with suction pipe 2 are attached to the pipe 3 and conveyor 5 arranged. When loading, the procedure is as follows:

The material 7 is sucked from the stack with the device at the mouth of the suction tube 2 against the open side of the hollow rail 1 and thereby against the conveying means 5, whereby the conveyed material 7 itself first becomes a valve that partially closes the entrance of the Savgrohree 2 and secondly, the U-bracket 1 continuously and depending on the need covers the open side, ie the suction tube is extended as desired. The negative pressure thus comes into effect along the hollow rail until all of the material 7 is lifted from the stack against the conveying means 5 guided on the hollow rails 1, which in practice happens very quickly. The material 7 lifted from the stack is transferred in a known manner by the conveying means 5 to a further conveying device 6 outside of the Unterdruokbereiohs. The adjacent sheet of material 7 is lifted as soon as the lower edge of the suction tube 2 from the previous sheet is added, so that continuous opening takes place.

In the embodiment according to FIGS. 3 and 3, the hollow rails H _9, which also consist of a U-profile that is open at the bottom, are bent at their web side at an obtuse angle. At the lowest point and viewed in the conveying direction, at a higher point of the upwardly inclined hollow rail, suction pipes 12, 13 are connected, which receive negative pressure from collecting pipes 14. On both sides of the hollow rails 11 are conveying means, for example endless belts 15, which are guided over slide rails *) and the underside of which is again lower than the lower edge of the conveying means. A further transport device 16 is arranged below the end of the conveying means. The device also has a feed conveyor 18 for the material 17 to be sorted. The conveying means 13, which are arranged at a distance, are driven by a common shaft 19. The hollow rails 11 are separated by a wall 4 in front of the first suction pipe 12 and after the second suction pipe 13.

For sorting the material according to one of its dimensions, e.g. length or width, the second suction tube 13 is attached at a distance corresponding to the desired dimension, or if different dimensions are sorted, any number of bulbs can be sorted at a corresponding distance "EITB & i note only su _t that the smallest Oimeaeioß first, dl © gvuBte is as letgstse.

The way it works is as follows? The material to be sorted is carried out by a picking device, ' according to the Pig. 1,2 or any funding 18 The material is brought up from the first suction pipe 12 sucked on the Hohlscbiene and the conveyor. That The material now acts as it does for loading and conveying besehrlebten, as a valve and directs the negative pressure into the Hollow rail or, which is now through the material 17 forming suction pipe around.

If the front edge of the material 17 reaches and closes the suction tube 13 before the rear edge of the material opens the suction tube 12, it naturally runs a long way, before the process is repeated. But if the material is shorter than the distance between the two suction tubes 12, 13 _f , the rear edge of the material 17 opens the sav tube 12 before the front edge reaches the suction tube 13, which of course causes the hollow rail to immediately lose its pressure and the material falls off. This process can of course be repeated as often as desired using any number of suction pipes, so that any number of dimensions can be sorted.

Aueführuagebelspiel leg of FIG NaOH. 5 for stacking material iet the arrangement ia substantially the same as when loading according to FIGS. 1 and 2 * There are therefore, in this device the same BesugaKloben wit FCTI Figures' 1 and 2 are used. The TJntereofcitsd lies

in that the lifting platform 8 is arranged after the suction pipe 2 and the device does not have a removal means 6 but a feeder conveyor means 10. Of course here, too, two or more hollow rails 1 with conveying means 5 are arranged according to the width or length of the material.

When used for stacking, the operation is similar. The delivery of the material 7 happens again as described in FIGS. 3 and 4 by means of the Funding 10. The stacking takes place simply in that the trailing edge of the material exposes the suction pipe 2, whereby the hollow furnace 1 loses the negative pressure and the material falls onto the lifting platform 8 or the stack.

Me invention is based on the examples shown not limited. It can be horizontal, vertical, inclined ujafl even curved in any plane and any size can be used for a variety of materials.
