Description

Device for dl« output of in cardboard·
packaged goods in commisioning plants

The invention relates to a device for dispensing in
KartOM packed goods in order picking systems according to the preamble of claim 1*

Such devices are well known on the market. They have the disadvantage that each of the slides that operate the goods dispensing has its own drive system, which makes them very complex and prone to failure.

The object of the present invention is to create a device of the type mentioned at the outset which does not have this disadvantage.

This object is solved according to the invention in the characterizing features of claim 1. A device equipped according to the invention has the great advantage that a large number of slides that actuate the dispensing of goods from the goods storage compartments are operated by just one single drive device and only a small electromagnet is required to bring each slide into the working position. Such an arrangement saves expensive drive parts and thus makes the entire device less susceptible to failure. There is also the advantage that the device is able to handle cycle times of less than 1.5 seconds.
Further features and embodiments of the invention emerge from the following claims.

The invention is explained in more detail below using an embodiment shown in the drawing.

The drawing shows the device according to the invention in vertical section.

On the substructure 1, in which the drive device 2 is accommodated, a plurality, preferably 15 to 20 or more goods storage shafts 3 are arranged transversely to the drive device 2. In each goods storage shaft 3, the goods packed in boxes are shown in dashed lines and stacked vertically one on top of the other. Each goods storage shaft 3 has, at the level of the lowest cardboard layer 5, an output opening 6 corresponding to the size of the box, whereby the ejected box 4 fills a conveyor belt (not shown) running along the goods storage shaft 3 via a rod 7. The drive device 2 for the slides 8 used for the ejection process of the goods dispensing from the box storage shaft 3 is guided on a parallel rod 9 via ball bearings 10, 11 as slides 12 in the ejection direction, see direction of arrow. The slides 8 are freely mounted horizontally at one end 14 on a common shaft 13 arranged transversely to the ejection direction. Close to the ejection end 15 of the slide 8, an upward-acting electromagnet 16 is arranged under each slide on the carriage 12, which, when energized, brings the slide 8 into the working position shown in the right-hand part of the drawing. In the left-hand part of the drawing, the slide 8 and the electromagnet 16 are shown in the rest position, which is reached after the ejection process has ended and after the electromagnet 16 has been switched off. So that the slide 8 can fall downwards after the ejection process has ended, a slot 18 is provided in the guide track of the slide 8 in the base 17 of the goods storage shaft 3, the opening width of which is designed so that the slide 8 falls through with play. The slot 18 merges into the opening 19 on the rear wall 20 of the goods storage shaft 3, into which the slide 8 engages during the ejection or dispensing process. After the slider 8 has fallen down, the next carton 4 can slide onto the lowest carton layer 5 during the return movement of the slider 8. In order that the slider 8 remains below the carton storage shaft 3 in the rest position, but still grips the carton 5 approximately centrally in the working position without assuming an extremely inclined position, it is provided with an upwardly directed bend 21 on its ejection end 15.

&khgr; after

In order to prevent the slider 8 from moving upwards during the ejection process, there is a stop on the rear wall opening 19.

According to a further aspect of the invention, the carriage 12 is driven by a crank mechanism 23, which is preferably arranged horizontally within the carriage 12 and is connected to the carriage 12 via a roller bearing 24 in a transverse slot 25. An electric motor (not shown) arranged outside the base 1 drives the crank mechanism 23 with a drive shaft 26. Of course, the crank mechanism 23 can also be designed in any other known remote control without departing from the scope of the invention.

The device itself is controlled by a computer-controlled pulse generator, whereby only the electromagnets 16 are excited and thus the associated valves are brought into the working position, from whose storage compartment 3 a box of goods is required for the picking of an order*
