Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION The present invention relates to a method of connecting a spinning frame and a winder, and relates to a passage between the spinning frame and the winder, and is very effective.

Prior Art Fig. 4 shows an example of a conventional method.
A transport band 201 consisting of an endless belt connecting the entire circumferences of the side and L sides in the horizontal direction and extending to the out-end (OE) side is rotated continuously or intermittently in one direction, and the next process winder 207 of the pipe yarn is The pipe supply device 204 and the pipe conveyor 206
The empty bobbin discharged from the winder 207 is conveyed to the empty bobbin supply device 205 via a suitable conveyance means, and the empty bobbin supply device 20
This is a method (hereinafter referred to as conventional method (1)) of receiving an empty bobbin from No. 5 to the peg 203. FIG. 5 shows a transport band 301 consisting of an endless conveyor belt installed along the R and L sides of the spinning frame 302, which is continuously or intermittently rotated in a reciprocating manner. The empty bobbins discharged from the winder 307 are conveyed to the empty bobbin supply device 305 via a suitable conveyance means, This is a method (hereinafter referred to as conventional method (2)) of receiving the empty bobbin from peg 305 to peg 303.
By the way, these conventional methods (1) and (2) have limitations such as the method of supplying the pipe thread to the pipe supply device in the next process, the pretreatment of the end threads of the pipe thread at the time of feeding, and the fact that the end threads are not returned from the winder. Due to the need for a temporary stock of empty bobbins, it is extremely difficult to provide a working passage between the spinning machine and the winder, and if one were to force the provision of a working passage, the pipe yarn conveying device would become extremely complicated and expensive. As a result, the frequency of delivery increases, leading to frequent disturbances of the pipe yarn, increasing the number of defects in end yarn processing in the next process, and reducing the efficiency of the winder. Therefore, unless a special thread stocking device is installed between the spinning machine and the winder, it is not possible to create a passage between the spinning machine and the winder, so the patrolling worker must start from point B ₄ as shown in Figure 6. When moving to F ₄ , use B ₄ , C ₄ , D ₄ , E ₄ , F ₄ movement method, or
The only option is to move B ₄ , A ₄ , H ₄ , G ₄ , and F ₄ , which has problems such as very poor workability.

Structure of the Invention The present invention extends the inclined portion of the transport band attached in the longitudinal direction of the spinning machine and the inclined portion of the empty bobbin conveyor attached in the longitudinal direction of the winder, and creates a working passage below the inclined portion. In this method, a working passage is provided between the spinning machine and the winder, and the above-mentioned problems are solved by using a very simple system and device.

The present invention will be described in detail below based on drawings and examples.

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 spindles are arranged on both sides, and FIG. 2 is a side view of FIG. 1.

Receiving empty bobbins 18 to the spinning frame 02 along the R side and L side frames of the spinning frame 02, and
A transport band 01 is attached for supplying the pipe yarn 19 doffed from 2 to the next process. The transport band 01 has a peg 01-2 on its entire upper surface at a pitch half the spindle pitch of the spinning frame 02, and rises on its OE side to carry the pipe yarn 19 doffed from the spinning frame 02 next. It extends to a pipe and yarn chute 04 for supplying to the process. The pipe 19 is transferred to the pipe chute 04 by intermittent rotation in the direction of the transport band 01, and is removed from the peg 01 by a suitable pipe removal device.
-2 and sent to the pipe supply device 05 via the pipe thread chute 04 common to the R and L sides. The tubular yarn chute 04 is equipped with an irregularly shaped yarn discharging device, and the irregularly shaped yarn is discharged out of the system and stored in an irregularly shaped yarn box 04-22 (not shown) via a chute etc. Only the thread is sent to the pipe supply device 05. The pipe supply device 0
The pipe yarn 19 introduced in step 5 is appropriately treated with end yarns,
In response to a request signal from the winder side, the tube yarn 19 is supplied from the tube supply device 05 to the tube conveyor 06 attached to the front surface of the winder in the longitudinal direction, and further supplied to the winder 08 via the magazine gate and magazine 07 on the way, and the tube yarn 19 is wound up. It will be done.

The empty bobbin 18 delivered from the winder 08 to the empty bobbin conveyor 09 is transferred to the empty bobbin conveyor 09.
The conveyance pitch of the empty bobbins 18 is unified at the rising part of the bobbin with remaining yarn attached to the inclined part.
At step 1, the bobbin with residual thread is discharged out of the system and stored in the bobbin with residual thread box 09-22 via a chute etc., and only the normal empty bobbin 18 with no remaining thread is transferred to the empty bobbin alignment device via the empty bobbin chute 09-21. 13
It is now being transported to The empty bobbins are arranged with the larger bobbin diameter in the traveling direction by the empty bobbin aligning device 13, and are sequentially conveyed to the empty bobbin stock conveyor 14 in a line, and during normal operation, the most advanced empty bobbin 18 Empty bobbin stopper 15 attached to the tip of empty bobbin conveyor 14
The empty bobbins 18 that follow are also stored in sequence.

An empty bobbin supply section 17 is provided at a location away from the center of the spindle of the end weight on the gear end (GE) side of the transport band 01 by an appropriate distance, and the empty bobbin supply section 17 is provided at a position away from the center of the spindle at the end weight on the gear end (GE) side of the transport band 01. The empty bobbin is sent to the empty bobbin supply section via the bobbin stopper 15 and the RL switching gate 16, and is supplied onto the transport band 01 via the empty bobbin supply section 17.

The flow of the yarn and empty bobbin in the above embodiment can be summarized as shown in FIG. 8.

Further, the relationship between the production amount (number of tubes) of the spinning machine and the processing time of the winder in the above embodiment is illustrated in FIG. 3. In Fig. 3, the vertical axis shows the amount of tube yarn supplied and the amount of empty bobbins received (Nc), and the horizontal axis shows time (Ts). The _time when the yarn becomes movable again due to the request of If the time during which transport band ₀₁ cannot be moved freely due to
The time required for the cycle is Tz. In other words, the longest time required for the transport band 01 to complete the supply of the pipe yarn 19 to the next process and the reception of the empty bobbin 18 to the transport band 01, and to be ready for the next doffing operation is T _Y. become. Third
Point A in the diagram is point B after doffing work is completed and transport band 01 movement can start T _Y hours later.
is the deadline for completing preparations for the next doffing operation. Figure 1 Between point F of the R-side yarn supply section and point _E of the R-side OE end weight, and point C _of the L-side yarn supply section and the weight of the _L -side OE end.
Between points B _{and 1} , the pipe yarn doffed in the previous doffing operation remains on the OE side of the transport band 01, so the pipe yarn on the R side is moved at the same time as the transport band 01 starts moving. Supply to the next process is started, and at the same time reception of empty bobbins to the transport band 01 is started. When the pipe yarn doffed at _one point on the R side GE end weight part D passes through _{the one} point on the R side OE end weight part E, n pieces of the pipe thread 19 on the R side are supplied and n pieces of the empty bobbin 18 are supplied.
After the book reception is completed, the supply of the L-side tube yarn 19 and the reception of the empty bobbin 18 are started. When the pipe thread 19 doffed at _one point on the L side GE end weight part A passes through the L side OE end weight part, n' pieces of pipe thread 19 on the L side are supplied and n' pieces of empty bobbin 19 are received. The process is completed and at the same time, the preparation for next doffing is completed. Therefore, regardless of whether there is a stock zone for the yarn or the empty bobbin, the minimum line for supplying the yarn to the yarn is the solid line AB in Figure 3, where n=n', so the lower limit of the required winding capacity of the winder is
2n/T _Y (books/hour). In other words, the yarn supply and empty bobbin reception start and end at the same time, and there is no need for a run-up before the start of supply or a run-up until the initial conditions are restored after the supply is completed, which is different from conventional techniques (1) and (2). There is no need for a special yarn stock zone or empty bobbin stock zone, and since there is no frequency of transfer of the yarn from the transport band 01 to the time it is fed into the yarn supply device 05, there is no disturbance of the yarn during transportation. . The present invention aims to provide a working passage between the spinning machine and the winder without impairing the features of the system as described above, so that the user can reach the destination in the shortest distance as shown in Figure 7. It is something. As can be seen from Fig. 2, the inclined part of the transport band 01, that is, the rising part on the side where the pipe thread on the transport band is transferred to the next process, is extended, and the pipe thread removal part is brought overhead. Furthermore, by similarly extending the inclined portion of the empty bobbin conveyor 09 for returning the empty bobbins discharged from the winder to the spinning machine side, by an amount corresponding to the length of the transport band. A working passage is provided between the spinning frame and the winder, and also under the tube yarn conveying device and the empty bobbin conveying device, through which a worker can go back and forth for patrol work.

Effects of the Invention The present invention supplies a yarn from one end of a transport band to the next process and receives an empty bobbin from the other end of the transport band at the same time. Unnecessary and increases winder capacity to 100
%, and without compromising the features of the system, which eliminates problems such as yarn disturbance during transport and empty bobbin bridging. A passage can be provided between the two, which has a great effect on making patrol work easier and improving efficiency.
