Description
- The invention relates to a method for supplying empty tubes to attending devices of a textile machine, particularly of a spinning machine, in which empty tubes are supplied unidirectionally by means of a conveyor to the workstations of the textile machine, at which the attending devices requesting a new tube are positioned.
- In addition, the invention relates to a device for supplying empty tubes to at least two attending devices arranged displaceably along at least one row of workstations of a textile machine, particularly of a spinning machine, in which each row of the workstations is provided with a container of empty tubes and a one-way conveyor of empty tubes, whereby the machine is equipped with a control unit which is coupled to the individual workstations of the machine, to the tube container, to the tube conveyor for the respective side of the machine and to the attending devices.
- Automatic spinning machines which wind the spun-out yarn in their winding device on a final bobbin are usually equipped with several attending devices moving along rows of workstations.
- In some spinning machines there is always one empty tube stored at each workstation, which is replaced after being removed and placed into the winding device of the workstation. That requires monitoring the state of the tubes at the workstations, which is usually performed by the operator. Moreover, there is a need for a special complicated mechanism for removing the tube from the conveyor and placing it in a storage place.
- Other known devices typically have one reserve empty tube seated on an attending device, whereby after the attending device is brought to the workstation requesting the replacement of a fully wound bobbin with an empty tube, the reserve empty tube is removed by the means of the attending device from its container and placed into the winding device of the workstation. For the efficiency of the system, it is important, among other things, that the tube which has been removed is replaced on the attending device as soon as possible.
- In the case of spinning machines which are provided with two or more attending devices on one side of the machine due to avoidance of unnecessary stoppage times, it is necessary to solve the order of the attending operations of the attending devices so that the conveyor (usually a belt conveyor) will deliver the tube from the container at the end of the machine to the specified attending device, or to the respective workstation without a risk of this tube being removed by another attending device which is situated between the specified attending device and the container. This is the drawback of the current spinning machines in which the transport of the empty tubes to the attending devices is realized by one one-way belt conveyor.
- For example,
EP 1675797 B1 which describes a method and a device according to the preamble ofindependent claims Fig. 1 schematically represents a part of the spinning machine according to the background art and comprising a row of workstations A1 to A13, whereby a one-way container C of the tubes D is provided at the end B of the machine. Next to the container C is located a belt conveyor E of the tubes which extends along a row of the workstations A . Three attending devices G are located on the travel rail F. - At the workstation A9 it is necessary to exchange a fully wound bobbin for an empty tube D . The attending device G2 moves to the workstation A9 and via the control unit of the machine requests supplying the tube D . The tube D1 is placed by the container C on the conveyor E , which transports it in the direction S of its movement to the workstation A9 . After the request of the attending device G2 , but still during placing the tube D1 on the conveyor E, the attending device G1 stops at the workstation A4 and requests the tube D as well. In this situation, the control unit evaluates the mutual position of the workstations A4 and A9 with the attending devices G1, G2, G3 positioned at the workstations A4 and A9 and suppresses the request of the attending device G1 and the tube D1 removal from the conveyor E is not allowed until the attending device G2 receives the tube D1, or, optionally, until the tube D1 has passed by the attending device G1 .
- Nevertheless, in many cases the mutual position of the workstations A4 and A9 with the attending devices G1 and G2 positioned at the workstations is very disadvantageous due to the time needed for automatic suppression of the request of the attending device G1 situated closer to the container C . Therefore, this system is efficient only in some cases at a certain specific favourable mutual position of the attending devices and/or the workstations which request insertion of a new empty tube.
- Therefore, the goal of the present invention is to improve the time utilization of the attending devices when replacing fully wound bobbins with empty tubes at the workstations of spinning machines.
- The goal of the invention is achieved by a method for supplying empty tubes according to
independent claim 1 and by a device for supplying empty tubes according toindependent claim 7. The principle of the method consists in that during the presence of at least one tube on the running conveyor and the simultaneous request of another attending device for supplying a tube, another tube is placed on the running conveyor and at least the mutual position of the machine workstations requesting a new tube, at which the attending devices are positioned, is evaluated and the control unit makes the decision on optimal assignment of the tubes present on the running conveyor to the attending devices requesting for a new tube with respect to the optimal use of the working time of the machine. This optimization shortens the time when the workstations do not work, thus increasing machine productivity, which is particularly important especially in modern high-performance spinning machines with a plurality of attending devices, whereby the greater the number of the attending devices, the more important the solution according to the invention is. - Another improvement is achieved in an advantageous embodiment, when prior to making the decision on the optimal order of assigning the tubes present on the running conveyor to the attending devices requesting a new tube the actual time point of the need for an empty tube and the current position of the tubes on the conveyor are evaluated.
- Also, it is advantageous if the actual time point of the need for an empty tube is evaluated on the basis of the current and/or future servicing activity of the respective attending device and the expected duration of this operation/these operations.
- In the case of spinning out different batches of yarn on one machine at the same time, different colours of the tubes are used for differentiation. In these cases, before making the decision on the optimal order of assignment of the tubes present on the running conveyor to the attending devices requesting a new tube, the color of the tube is evaluated.
- The principle of the device for supplying empty tubes consists in that the control unit is provided with a decision algorithm for the optimal order of assignment of the tubes present on the conveyor to the individual attending devices requesting a new tube on the basis of at least the mutual comparison of the positions of the workstations of the machine, at which the attending devices requesting a new tube are positioned.
- In a preferred embodiment, the decision algorithm is also provided with data sets for evaluating the actual time point of the need for empty tubes and the position of the tubes on the conveyor, whereby these data sets preferably contain information about types of the attending operations of the attending devices and their duration.
- If necessary, the decision algorithm is provided with data sets for evaluating the colour of the tube and its assignment to certain workstations.

Fig. 2 schematically represents a part of a spinning machine equipped with a device according to the invention for improving the supply of empty tubes to attending devices which are able to move to the individual workstations of the machine. The transport of fully wound bobbins from the workstation of the machine is not the subject of the device according to the present invention. -
Figs. 2 and3 show onerow 1 of the workstations 11nn of thespinning machine 100 , which are in the illustrated embodiment attended to by three attendingdevices - The attending devices move along the
row 1 of theworkstations 11 along aguide rail 10. Each attendingdevice container 102 ofempty tubes 5 is arranged at the end 101 of themachine 100. Next to thetube container 102 is located an endless one-way conveyor 6 of thetubes 5 , arranged along therow 1 of theworkstations 11 , whose storage surface is within reach from an unillustrated handling means of the attendingdevices tubes 5 can be transported on theconveyor 6 at the same time. - The attending
device empty tube 5 transported by theconveyor 6 and for its transfer to a standby position on the attendingdevice tube 5 on theconveyor 6 relative the standing attending device, and a gripping means 72, which transfers it to the above-mentioned standby position on the attendingdevice - According to
Fig. 3 , the attendingdevices spinning machine 100 are connected viabidirectional lines control unit 8 of thespinning machine 100, to which is also connected anunillustrated device 9 for transferring theempty tubes 5 on the one-way conveyor 6 via theline 81 , as well as other unillustrated means of thespinning machine 100. - In
Fig. 2 the first attendingdevice 2 is situated near thecontainer 102 next to theworkstation 1103 in the direction away from thecontainer 102 of theempty tubes 5 . The second attendingdevice 3 is situated downstream of the first attendingdevice 2, as shown inFig. 2 , next to theworkstation 1116. The third attendingdevice 4 is situated at theworkstation 1149, downstream of the second attendingdevice 3 , operating to look after the end portion of therow 1 of the workstations 11nn. - At the time when replacement of a fully wound bobbin with an empty tube is not required, the attending
devices - The operation of the device for supplying the
empty tubes 5 , or 51, 52, 53 to the attendingdevices Fig. 2 . - For example, at the
workstation 1117 it is necessary to replace a fully wound bobbin with anempty tube 5 , or just insert theempty tube 5 into the winding device of the workstation, or transfer theempty tube 5 into a standby position of the attending device. The second attendingdevice 3 moves to thisworkstation 1117 and requests anempty tube 5. Theconveyor 6 with the first tube 51 intended for the second attendingdevice 3 starts moving. The waitingsecond attending device 3 initially inserts itsreserve tube 5 into the winding device of theworkstation 1117 and performs further operations. At the same time, its unillustrated stop means 71 is extended to the area of theconveyor 6. - Already at the time of transporting the first tube 51 by the
conveyor 6 there is often a need for replacing a fully wound bobbin with anempty tube 5, also at another workstation, in the example shown it is at theworkstation 1103, which is situated relative to theworkstation 1117 closer to thecontainer 102 of theempty tubes 5. The first attendingdevice 2 stops at theworkstation 1103 and before the preceding request of the attendingdevice 3 has been fulfilled, requests anempty tube 5. The second tube 52 from thecontainer 102 is placed on the runningconveyor 6. Thecontrol unit 8 evaluates the optimal assignment of the tubes 51, 52 to the attendingdevices - In the current situation, the
control unit 8, for example, leaves the first tube 51 for the second attendingdevice 3, and the tube 52 is assigned to the first attendingdevice 2. The stop means 71 of the second attendingdevice 3 may remain extended, whereas the stop means 71 of the first attendingdevice 2 will be retracted until the first tube 51 has passed by it, whereupon it is extended. Thus, both the attendingdevices workstations device 3 waiting for the tube 51 and the first attendingdevice 2 waiting for the tube 52. - In another case, it is necessary to replace a fully wound bobbin with an empty tube at the
workstation 1103 . The first attendingdevice 2 stops at theworkstation 1103 and requests an empty tube. The conveyor with the first tube 51 intended for the first attendingdevice 2 starts moving. The first attendingdevice 2 is waiting for the tube 51, its unillustrated stop means being extended to the area of theconveyor 6 . Simultaneously, it inserts itsreserve tube 5 into the winding device of theworkstation 1103 and performs further operations. - Subsequently, also at the
workstation 1117 it is necessary to exchange a fully wound bobbin for anempty tube 5 . The second attendingdevice 3 stops at thisworkstation 1117 and before the preceding request has been fulfilled, requests anempty tube 5 . The second tube 52 is placed on the runningconveyor 6 . Thecontrol unit 8 evaluates the optimal assignment of the tubes to the attendingdevices - In the first alternative, the first tube 51 will be intended for the second attending
device 3 and the second tube 52 will be intended for the first attendingdevice 2 . Thus, there will an exchange of the target attending devices, since originally the first tube 51 was intended for the first attendingdevice 2 , but after receiving the request from the second attendingdevice 3 and after the decision according the decision algorithm, the first tube 51 will be intended for the second attendingdevice 3 and the second tube 52 for the first attendingdevice 2 . The stop means 71 of the first attendingdevice 2 must be retracted and after the passage of the first tube 51 intended for the second attendingdevice 3 it must be extended. The attendingdevices - In the second alternative, the first tube 51 will still be intended for the first attending
device 2 and the second tube 52 will be intended for the second attendingdevice 3. The stop means 71 of the first attendingdevice 2 stops the first tube 51 on theconveyor 6 , whereupon after it is removed by the grippingmeans 72, the stop means 71 of the attendingdevice 2 is retracted, the stop means 71 of the second attendingdevice 3 may be extended immediately. The attendingdevices - In the following example, a combination for the three attending
devices - At the
workstation 1149 it is necessary to replace a fully wound bobbin with an empty tube. The third attendingdevice 4 stops at thisworkstation 1149 and requests an empty tube. The conveyor with the first tube 51 intended for the third attendingdevice 4 starts moving. The third attendingdevice 4 is waiting for the tube 51 , its unillustrated stop means 71 being extended to the area of theconveyor 6 . At the same time, it inserts itsreserve tube 5 into the winding device of theworkstation 1149 and carries out further operations. - Afterwards, at the
workstation 1103, too, it is necessary to replace a fully wound bobbin with anempty tube 5 . The first attendingdevice 2 stops at thisworkstation 1103, and before the preceding request has been fulfilled, requests anempty tube 5 . The second tube 52 is placed on the runningconveyor 6 . Thecontrol unit 8 evaluates the optimal assignment of the tubes to the attendingdevices device 4 and the tube 52 for the first attendingdevice 2. The first attendingdevice 2 is waiting for the tube 52, extending the stop means to the area of theconveyor 6 only after the passage of the first tube 51 intended for the third attendingdevice 4 . Simultaneously, it inserts itsreserve tube 5 into the winding device of theworkstation 1103 and performs other operations. - In addition, also at the
workstation 1117 it is necessary to exchange a fully wound bobbin for anempty tube 5 . The second attendingdevice 3 stops at thisworkstation 1117 , which, before the preceding requests have been fulfilled, requests anempty tube 5 . The third tube 53 is supplied on the runningconveyor 6 . Thecontrol unit 8 evaluates the optimal assignment of the tubes to the attendingdevices - In the first alternative, the first tube 51 will be still intended for the third attending
device 4 , the second tube 52 will be in this case intended for the second attendingdevice 3 and the third tube 53 will be intended for the first attendingdevice 2 . The stop means 71 of the third attendingdevice 4 will remain extended, while the stop means 71 of the second attendingdevice 3 will not be extended until the first tube 51 has passed by it, and finally the stop means 71 of the first attendingdevice 2 will not be extended until the passage of the first tube 51 and the second tube 52 . The attendingdevices - In the second alternative, the first tube 51 will be intended for the third attending
device 4 , the second tube 52 will be intended for the first attendingdevice 2 and the third tube 53 will be intended for the second attendingdevice 3 . The stop means 71 of the third attendingdevice 4 will remain extended, the stop means 71 of the first attendingdevice 2 will be extended only after the first tube 51 has passed by it and the stop means 71 of the second attendingdevice 3 will be extended only after the passage of the first tube 51 . The second tube 52 is initially removed by the first attendingdevice 2 and only then the third tube 53 for the attendingdevice 3 moves past the first attendingdevice 2 . The attendingdevices - The algorithm for the optimal order of assignment of the
tubes 5 present on theconveyor 6 to the individual attendingdevices new tube 5 , which contributes to the optimal use of the time of the spinningmachine 100, in this manner decides about the order of supplying the attendingdevices empty tubes 5 . In doing so, it uses the criteria, such as, first of all, the current mutual comparison of the positions of the attendingdevices tubes 5 on theconveyor 6 , or, as the case may be, other criteria, such as different colours of thetubes 5 from the point of their assignment to certain workstations, etc. - The operation of the device according to the invention is schematically represented in a table in
Fig. 4 , wherein only the mutual position of the workstations being attended to and the current position of thetubes 5 on theconveyor 6 are evaluated. In the first three columns of the table there are the attendingdevices container 102 of theempty tubes 5 arranged in ascending order according to their reference numerals. In each row of these three columns, the attendingdevices empty tube 5 were made. Indicated in the other tree columns are the variants of assignment of the tubes 51 , 52 , 53 to the respective attendingdevice control unit 8 of the spinningmachine 100 . - If an error occurs on the attending
device respective tube 5 , this does not interfere with the removal of the respectiveother tubes 5 by the other attending devices. According to one embodiment, therespective tube 5 intended for the attendingdevice respective tube 5 , which is intended for the defective attendingdevice tubes 5 , is transported to the initial position on theconveyor 6 , for example, by reverse movement of theconveyor 6 , where it waits until it is requested by another attendingdevice tube 5, which is already at the beginning of theconveyor 6 , thenew tube 5 is not placed on theconveyor 6 and the operation of the device is started, i.e., the transport of the tubes according to the present invention begins. - The invention is not limited to three attending devices. Using three attending devices serves only as a basic example of embodiment used here to explain the principle of the invention, and the actual number of the attending devices used in the machine depends on the specific requirements of the machine and automation of its operation.
