Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can transport system between two drawing machines whose processes are successive.

[0002]

2. Description of the Related Art A can-conveying system between two successive drawing machines, wherein a sliver can is moved forward by at least one conveying device and at least partially circulated on a closed conveying path. Groups are in direct contact with one another, in which closed transport paths are formed as polygons, the sides of which surround the corners of each other.

[0003]

In a known device (German Offenlegungsschrift 1 281 903), a full can is processed in a downstream mill. For this reason, Manchus is U
It is arranged in the shape of a letter. When the full cans are empty, they are sequentially sent one by one to a drawing machine provided in front. The front drawer fills the empty can with sliver. Each of the filled cans is sequentially sent one by one to a downstream drawing machine. In this case, an installation space is provided before and after the filling station of the preceding drawing machine for empty or full cans, respectively. The disadvantage is that the downstream mill remains in the standby position until the required number of full cans has been sent, thereby causing a considerable loss of time. Furthermore, since the loading and unloading of empty and full cans is interdependent, this latter can transport system is disadvantageous in that it is not flexible due to the forced connection.

An object of the present invention is to avoid the above-mentioned disadvantages,
The object of the invention is to provide a can transport system of the kind mentioned at the outset, which increases the processing speed and allows a flexible operation.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an apparatus according to the present invention is provided with some filling between a front drawing machine and a rear drawing machine. There is at least one can reservoir, between the downstream draw machine and the front draw machine at least one can reservoir for several empty cans, Each of the reservoirs is configured as a transport trajectory including a transport member to be driven.

[0006] The presence of a can reservoir for empty cans and a can reservoir for full cans, respectively, between the preceding and subsequent drawing machines allows the latter to be used. Already while processing some full cans, some empty cans can be filled with sliver in the front mill.
By configuring the cans reservoir as a transport device,
An empty can and a full can can be loaded and unloaded between the front and downstream drawing machines by a flexible operation.

It is preferable that the empty can reservoir and the full can reservoir are arranged one behind the other in the transport direction. Conveniently, the conveying member of the conveying track comprises at least one endless conveying belt, conveyor belt, rollers, etc., provided with a drive.
It is advisable to add a detent member to the leading can in the transport direction (A, B). Advantageously, the transport member, for example the transport belt, can slide under the dammed can. Preferably, the empty can reservoir is configured as a stagnant reservoir (extrusion reservoir). It is expedient for the full can reservoir to be configured as a stagnant reservoir (extrusion reservoir).
Advantageously, the empty can reservoir has at least two transport tracks. Advantageously, the full can reservoir has at least two transport tracks. Preferably, the extrusion reservoir allows the separation of full and empty cans. One sliver circulating
Preferably it is advanced in one direction.
