DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The instant invention relates to a process and to a device for the storage of cans, in particular at a fiber sliver producing machine which is fed empty cans from the storage device and from which full cans are conveyed to the storage device, in which the filled cans are taken out of the storage device and are replaced by empty cans.
Processes and devices of this type are known from DE 40 15 938 wherein a can conveying vehicle here moved to a can storage device and deposits an empty can in a storage device provided for empty cans. The can conveying vehicle then continues to travel for a given distance so that it is able to receive a full can from a storage device for full cans. The empty cans as well as the full cans in the storage device are conveyed by means of a retaining conveyor to a respective receiving station. The storage device must furthermore be laid out so that the same number of empty cans as full cans can be accommodated in it at the same time. This means that much space is required for the can storage.
The retaining conveyor can deliver empty cans only at the end of the retaining path for the empty cans. Full cans on the other hand, can be received reliably only at the beginning of the retaining path. This has the disadvantage that the can conveying vehicle must travel to several locations to deliver and to receive the cans.
OBJECTS AND SUMMARY OF THE INVENTION
It is therefore a principal object of the instant invention to create a process and a device by means of which cans can be placed in a storage device and can be taken from same at low construction and control costs. Additional objects and advantages of the invention will be set forth in part in the following description, or will be obvious from the description, or may be learned through practice of the invention.
According to the invention the storage device is shifted for the reception or delivery of the can, so that an empty can or a full can may be brought as needed to an empty can receiving site. It is advantageous in this process according to the invention that control of only the storage device is required. The feeding and receiving of cans takes place advantageously at one and the same location. Shifting and sophisticated positioning of the device to receive and deliver cans from and into the storage device is avoided. The needed location on the storage device is always presented to the can grasping device by shifting the storage device. This enables the can grasping device either to take up an empty or a full can or to deposit an empty or a full can on the empty can receiving site.
By using the storage device as a replaceable storage device it becomes advantageously possible to exchange a storage device containing full cans against a storage device with empty cans. As a result, stoppages during the filling of cans are avoided to a great extent. If fewer full cans are taken from the storage device than are conveyed by the machine to the storage device, the completely full storage device can be removed manually or automatically from the machine and can be replaced by a storage device with empty cans.
The removal of a full can from the storage device takes place advantageously at a point in time when another can is outside the storage device, e.g., as the can is being filled. At this point in time, the storage device contains an empty can holding space on which a received full can is deposited in the storage device against an empty can. An orderly depositing of the cans in the storage device and thereby the possibility of carrying out a can exchange through a slight movement of the storage device is possible if the full cans are deposited on one side of the storage device, and the empty cans on the other side of the storage device.
Advantageously, an empty can is deposited in the storage device against a full can which is taken from the storage device. In this manner, the same number of cans are always present in the storage device before and after the can exchange. To maintain the orderly manageme
