Abstract

On the frame, above the rotating base, there are fixed transition surfaces, in front of which there is a transport surface, while on each side the frame is terminated by a shaft with a pair of gear wheels for a pair of chains interconnected by bars. The transport surface is formed by driven rollers or an extended transition surface.

Description

(54) Bag handling equipment

Transition surfaces are mounted on the frame above the rotary washer, in front of which a conveying surface is provided, on each side of which the frame is terminated by a shaft with a pair of gears for a pair of chains connected by bars.

The conveying surface is formed by driven rollers or an extended transition surface.

invention; relates to a device for handling bags when palletizing bags.

Up to now, the bags have been rotated 90 ° by means of a pull-out stop located on the driven roller conveyor. The bags had to be precisely aligned and the rollability of the roller conveyor was dependent on the roller speed.

These drawbacks are eliminated in the bag handling device of the invention, wherein the transition surfaces are mounted on the frame above the turntable, in front of which the conveying surface is fixed, the frame being terminated on each side by a pair of gear shafts for the pair. chains connected by bars. The conveying surface consists of driven rollers or an extended transition surface.

The bag handling device reliably rotates the bags by 90 ° and aligns the bags simultaneously prior to rotation.

The device according to the invention is in plan view shown in FIG. 1 and a front view of FIG. 2. The procedure for handling the bags is shown in FIG. 3 to 7.

Transition surfaces 2 are fixed on the frame 1 above the rotary washer 3, in front of which the conveying surface is fixed, on each side the frame is terminated by a shaft with a pair of toothed racks 5 for a pair of chains 6 connected by bars. is formed as an extended transition surface.

In the basic position, the strips 7 are below the upper level of the rollers 4 and the turntable 3. Uneven bags are conveyed to the driven rollers 4. The rollers 4 stop and the bar 7 pushes the bag over the transition surface onto the rotary washer 3. The bar reverses and the rotary washer 3 and the bag are rotated 90 °. Upon rotation, the bar moves the rotated bag over the transition surface 2 to another device. In the pallet bag layers, the individual bags are oriented differently, FIG. 3, 4.

The bag handling device allows the handling of pairs of bags. After pressing the first bag on the rotary washer 3, the bar 7 returns to the starting position and presses the rotary washer of the second bag - fig. 7th

If the bags fall out of the filler 4 instead of the rollers 4, they can be replaced by an extended transition surface 2 from which the bar 7 presses the bags onto the rotary washer 3.
