Description

[Detailed Description of the Invention] Purpose of the Invention The present invention relates to a device for transferring empty bobbins from a winder to a spinning machine in a system that connects a spinning machine and a winder, and which automates the transfer between spinning and winding processes. This is intended to solve the rigidity of installation, which is considered to be extremely difficult with conventional techniques, and to reduce equipment costs.

Prior Art Fig. 11 shows a front view of an example of a direct connection system between a spinning frame and a winder, which was developed by the present inventors and filed a patent application, and Fig. 12 is a plan view of the spinning machine and a winder. It is a diagram showing a combination of one winder and one winder. That is, the pipe yarn 301 doffed from one of the transport bands 102 attached to the spinning frame 101 is sequentially transferred to the pipe yarn discharge side while the transport band 102 is rotated intermittently. , the transport band 1
After the end yarns of the pipe yarn 301 are processed by the end yarn processing device 107 attached in the middle of the pipe yarn chute 1
After introducing the end yarn into the hollow part of the bobbin, the end yarn is introduced into the hollow part of the bobbin.
It is supplied to the winder 113 via a winder 113 and wound up by the winder. Empty bobbins discharged from the winder 113 are sent via an empty bobbin conveyor 114 and an empty bobbin alignment device 117 onto an empty bobbin conveyor 118 provided above the spinning machine, and are temporarily stopped on the conveyor by the action of an empty bobbin stopper 119. The empty bobbin stopper 119 repeatedly opens and closes in response to the intermittent rotation of the transport band 102, and the transport band 10
An empty bobbin 302 is received in the second empty peg.

The major feature of this method's transport device for pipe threads and empty bobbins between the spinning and winding processes is that there is no need for any special pooling equipment for pipe threads and empty bobbins between the spinning and winding processes. The equipment for transporting yarn and empty bobbins between yarn processes is extremely simple, easy to operate and maintain, there are almost no troubles during the transportation of yarn and empty bobbins, and there is no need for a pool or space for supplies. It is possible to install or remodel one set at a time, and immediate effects can be expected from each set, so the investment efficiency remains the same regardless of the size of the equipment. However, since this system is basically a combination of one spinning machine and one winder, the number of drums per winder decreases, and the equipment cost per drum on the winder side becomes relatively high. This resulted in an increase in operating costs. As described above, the above system has problems that need to be solved in terms of equipment flexibility, versatility, and cost.

Structure of the Invention The present inventor has made extensive research into a system in which the required winder stands can be arbitrarily combined with multiple spinning machines, and has not fixed each spinning machine to a specific winder.
The present invention has been achieved by developing a system that allows combinations with any winder within the same block to be quickly and freely selected with almost no need for hardware rearrangement.

That is, the first invention of the present invention is a device for transferring empty bobbins from a winder to a plurality of spinning machines, in which a winder-unit transport band that passes over one end of a transport band attached to a spinning machine and extends over all the spinning machines. A conveyor for carrying empty bobbins is installed at each conveyor, and a branch gate is provided at each position corresponding to the transport band of the conveyor, allowing the line of empty bobbins to be switched between the conveyors, and the opening and closing of the branch gate is controlled. By doing so, an empty bobbin can be returned from any winder to any spinning machine, and the second invention further includes the steps of the first invention.
The conveyor on which the empty bobbins are loaded is provided with means for transferring the empty bobbins to the return conveyor of the conveyor, and means for transferring the empty bobbins from the return conveyor to the forward conveyor at the rear end of the conveyor. Empty bobbins overflowing at the tip of the bobbin loading conveyor are conveyed to the rear end of the conveyor using the return of the conveyor, and then transferred to the outbound conveyor again.

The present invention will be described below based on drawings and examples. Although the present invention is concerned with transferring an empty bobbin from a winder to a spinning machine, the present invention will be explained with an outline of the system added for ease of understanding.

Fig. 1 shows a plan view of one embodiment in which the method of the present invention is applied to a spinning machine in which transport bands are arranged on both sides, Fig. 2 shows a front view of the spinning machine side, and Fig. The figure shows a front view of the winder side.

The pipe yarn doffed on the transport band 02 attached to the spinning frame 01 is passed through the yarn chute 03, which allows line selection freely, to the spinning frame 01 at right angles to the target spinning machine. The yarn is transferred to the yarn conveyor 04, which is attached in parallel in the same number as the target winders 13 over the entire length of the spinning machine group, and transported to the winder side. The pipe yarn that has been transferred to the winder side is transferred to a conveyor 06 with pegs via a pipe lift 05. The peg-equipped conveyor 06 is attached with an end thread pre-processing device 07 having a tail thread removal function and a body winding correction function in order to increase the probability of threading the end thread into the hollow portion of the bobbin in the next step. The end yarn treated is fed into an end yarn threading tube 09 via a yarn chute 08, and the end yarn is introduced into the hollow portion of the bobbin. The threaded pipe is transported by a pipe conveyor 10 attached to the front of the winder, fed into a magazine 12 via a magazine gate 11 attached to each drum of the winder, and wound by a winder 13. It will be done. Empty bobbins are delivered to an empty bobbin conveyor 14 provided at the lower part of the winder 13, and while being conveyed on an inclined conveyor 15, bobbins with remaining yarn are removed, and only empty bobbins with no remaining yarn are transferred to an empty bobbin chute 16. The bobbin is transferred to the bobbin alignment device 17. The empty bobbins are arranged in the empty bobbin alignment device 17 so that the traveling direction of the empty bobbins is in the direction of the larger empty bobbin diameter, and then transferred to the empty bobbin conveyor 18 installed above the spinning machine in the length direction thereof. An empty bobbin stopper 19 attached to the leading end of the conveyor 18 causes the empty bobbins to stand by sequentially from the leading end, and as the empty bobbin stopper 19 opens and closes, one empty bobbin is released for each operation according to the present invention. It is transferred to the bobbin conveyor 20.

In this way, the present invention transports the empty bobbins discharged from an arbitrary number of winders and stored on each winder orthogonally to the spinning frame 01 in the same manner as the tube yarn conveyor 04, and spreads them over the entire length of the target spinning frame group. As many empty bobbin conveyors 20 as there are target winders 13 are installed in parallel, and as shown in FIG. 4 and FIG. An empty bobbin gate 23-1 is attached to each empty bobbin conveyor 20 for guiding the empty bobbin to fall to the empty bobbin chute 23. By switching the empty bobbin gate 23-1, the empty bobbin sent from which winder is Even an empty bobbin can be easily received into the peg 02-1 of the transport band 02 via the empty bobbin receiver 24.

In other words, when transporting empty bobbins between the winding and spinning processes using the present invention, the target spinning machine 0
1 and the winder 13, it is only necessary to change the empty bobbin gate 23-1.

In addition, in the case of a system such as the present invention, the empty bobbin gate 23 is transferred from a spinning machine located far away to a spinning machine located nearby when viewed from the winder side, that is, the empty bobbin transport side.
-1, the empty bobbins remaining during that time will overflow. In that case, for example, an empty bobbin box (not shown) is installed at the tip of the empty bobbin conveyor 20, and the empty bobbin conveyor 14 on the winder side is loaded and accumulated.
Depending on the operating conditions, the number of pipes and yarns processed in one cycle of the spinning machine will be reduced to several percent.
Approximately 10% is discharged outside the system, so it is necessary to additionally replenish empty bobbins each time. If the timing of replenishing the empty bobbins is delayed, there are problems such as lowering the operating rate of the equipment. ing.

The present invention solves this problem by using a method of returning overflowing empty bobbins to the supply side using a belt on the return side of the empty bobbin conveyor and transferring them to the original line again. .

That is, as shown in FIG. 6, the empty bobbin that overflows is attached with a guide 20-1 and a chute 20-2 at its tip, transferred to the belt conveyor 20-3 on the return side, returned to the supply side, and then transferred to the lift. 21
is used to transfer the material to the original line. At this time, if empty bobbins are also supplied from the supply side, two empty bobbins will overlap, which may cause trouble, so it is better not to operate the stopper 19 when an empty bobbin enters the lift and moves up. Figures 7 and 8 show the empty bobbin conveyor 20.
This is a diagram showing an example of a means for transferring empty bobbins to the return side conveyor 20-3 provided at the tip, in which the empty bobbin is removed from the empty bobbin conveyor 20 by the guide 20-1 and transferred to the return side conveyor 20-3. This figure shows the configuration for guiding and transferring the materials. 9 and 10 are diagrams showing an example of a means for transferring empty bobbins returned to the supply side by the return conveyor 20-3 to the empty bobbin conveyor 20, in which the empty bobbins on the return conveyor 20-3 are transferred to the cylinder. The figure shows a configuration in which empty bobbins are returned to the empty bobbin conveyor 20 in sequence by a lift 21 consisting of a push-out means 21-1, a return stopper 21-2, and a guide 21-3.

Effects of the Invention Even if the conveyance and supply of empty bobbins between the winding yarn and spinning processes is automated as in the present invention, the features of the conventional system described above are not impaired at all, and compared to the conventional system, it is possible to Empty bobbins can be transported and supplied to the spinning machine, so even if production conditions change and there is an imbalance between the production capacity of the spinning machine and the winding capacity of the winder, the number of spinning machines assigned to each winder can be easily reduced. It's a very flexible system because it can be changed.

2. There is no need to subdivide the winder, and the equipment cost per drum on the winder side has been significantly reduced.

3. There is no need to subdivide the winder, and the operating cost (electricity cost) per drum on the winder side has been significantly reduced.

4. This system can now be used with almost no modification or relocation of existing spinning machines and existing winders, and equipment costs have been significantly reduced.

5. The problem of overflow in replenishing empty bobbins in a spinning-spooling connection system using a combination of multiple spinning machines and one winder is solved.

We were able to achieve remarkable results.
