ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention concerns a procedure for the simultaneous transportation of cans capable of being filled with fiber band which are arranged in a row on a can rack and form one can group, and which are transported between a frame machine and/or a further textile machine or to a can depot, as well as an apparatus for the execution of this procedure.
In common knowledge, through DE 42 33 357 A1, is the use a transport vehicle to move several cans arranged in a row as a group and to bring said group to a wagon regularly available at a frame machine. At this point, the group of cans is transferred from the transport vehicle to said machine wagon. Cans are then exchanged, one for the other, between the wagon of the frame machine and the transport vehicle. For this purpose, it is necessary to allow one empty place on the transport vehicle for one can. Further, it is necessary to inch step-wise along the wagon of the frame machine, so that a full can from the wagon will be switched onto the transport vehicle, and an empty can switched from the transport vehicle to the wagon. For this operation, a complicated drive and control mechanism is required.
OBJECTS AND SUMMARY OF THE INVENTION
The purpose of the present invention is to create a procedure and a corresponding apparatus which simplifies the can transport to and from the work station of the frame machine. Additional objects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.
According to the invention, since a complete can group is exchanged each time, no apparatus is required to carry out complicated maneuvering and positioning at the frame machine, as this is necessarily carried out when one can after another must be exchanged between the transport vehicle and the frame machine. Because of this, the expenditure for the design, manufacture, material and time in comparison to the conventional methods and equipment is reduced.
In order that as little time as possible will be required for the exchange of the can rack at the frame machine, the procedure of the invention is enhanced in that the can rack with the can group is brought to a first holding station, from there moved to a filling operation in the first work station, and following that, to a second holding station. By the method there shown, the placement and pick-up of a can rack is, time-wise, independent of the filling of the cans.
By means of an advantageous design of the procedure of the invention wherein the filling at the frame machine is monitored, and dependent upon the progress of the filling of the cans of the can group in place on the frame machine, a signal is given for the exchange of the can rack with the full cans of this can group for another can rack with empty cans of another can group, assurance can be given that a can rack with empty cans will always be delivered to the frame machine at the right time and conversely, a can rack with full cans may be picked up.
It is practical if the can rack, which was exchanged on the frame machine for another can rack, and with unchanged accessories, now finds additional applications, whether this be for immediate processing of the fiber band in the cans of this can group, or for intermediate storage in a can depot which storage allows for feeding at a given time the fiber bands to a textile machine for processing. In this way, waiting times are shortened, which leads to an improved efficiency of the band processing textile machine.
The fiber band processing machines, i.e. flyer or open end spinning machines, exhibit a multitude of similar work stations. In order to put the procedure of the invention to use in an optimal fashion, it is advantageous, if the can rack, the work station of the textile machine and/or the storage placement of the can depot are uniform in regard to their dimensioning wherein the number of the cans belonging to a can group is so determined that at any time a group can rack finds place for a multiple integer thereof in the work station and/or in the depot.
If several can racks find a placement beside one another at a textile machine or in a can depot, the danger arises that by manipulating one can rack, the neighboring can rack will be pushed away. Under certain conditions, this can lead to disturbances of production. To avoid this undesirable shoving of can racks, the procedure in accord with the invention has been advantageously improved wherein the can rack is securely fixed in its work station and/or the depot and/or its transport medium.
As has been mentioned, a shortening of the waiting time at the frame machine has been found by monitoring the procedure of filling.
In similar manner, it is advantageous if a fiber band processing machine is provided with a monitoring system wherein the run-out or breakage of one or more of these fiber bands is recorded and a subsequent triggering of a function is caused by a number of such recordings, i.e. the triggering of an acoustic or an optical signal or even an exchange of the can rack.
For the carrying out of the procedure, an apparatus is provided for the simultaneous transportation of a group of cans capable of being filled with fiber bands, said transportation being between a slide conveyor located on a frame machine and a further textile machine or a can depot, the latter possessing a can rack for the acceptance of a can group arranged in row units. The can rack brought to the frame machine still remains there during the filling of the cans in the can group already on the can rack on the frame machine, and said group only leaves the frame machine after the complete filling-of the cans in common with their can group. Therefore, there is only required an essentially simple motion and control based operation for the exchange of these cans between the transport vehicle (can wagon) and the machine. This reduces the costs for the design, manufacture and the material for the previously required elements as well as saving time for the course of the processing
Through a practical improvement of the invention wherein a monitoring device is assigned to the frame machine for the supervision of the progress of the filling of the cans of the can group, the monitoring device in communication with a control device triggers, in dependency with the progress of the filling of the cans, a signal for the exchange of the can rack having the full cans of this can group exchanged for another can rack with empty cans of another can group, the waiting time can be shortened by a time centered coordination of the filling of the cans with the can exchange. By the term “can exchange” is understood the bringing of a can rack with empty cans to the frame machine, and the removal of a can rack with full cans therefrom, even when the bringing and removal of a can rack is done, time-wise, independently of one another.
In order to avoid a loading and unloading of the can rack on the fiber band processing textile machines and possibly at the provided can depot for the intermediate storage of the cans with attendant loss of time, it is advantageous if the invented apparatus is improved in that the can rack together with the can group is capable of being brought into an-additional work station which is assigned to the further textile machine or into a storage location in a can depot, and further to remain there during the processing of the fiber bands to be found in the cans of this can group, or during the storage of this can group.
For the optimal storage of can racks at, for instance, a textile machine or in a can depot, the said textile machine on the one hand and the can depot on the other are dimensionally coordinated with one another so that a multiple integer of can racks may simultaneously be placed beside one another at this textile machine or at a section thereof, for instance in a can depot.
If the slide conveyor of the frame machine is designed with an endless belt or an endless chain, upon which, for instance
