That is, the piston rod (80) of the fluid cylinder (79) installed on the fixed frame (78) is integrally formed with the flange portion (81), the columnar portion (82), and the conical portion (83). The guide rod (77) is fixed, and the action of the cylinder (79) causes the guide rod (77) to move between the standby position (77) and the lowest descent position (77a) indicated by the chain double-dashed line as shown in FIG. Move up and down. At the lowermost position of the guide rod (77), the conical portion at the lower end is the cylindrical support member (3
It is a position slightly entering the upper end opening of 0).

In addition, the plate (8
A magnet (85) is fixed to 4), and the magnet (85) attracts and holds the guide plate (31a) in the middle of the two-stage yarn feeding. That is, as shown in FIG. 7, the lower empty bobbin (60
When the a) is removed, the guide plate (31) is also removed at the same time and rises to the highest position (31a), so that only the guide plate (31a) is attracted to the magnet (85). On the other hand, when inserting the guide plate (31a) into the support member (30), the flange portion (81) pushes the guide plate (31a) downward when the guide rod (77) descends, and the magnet (8
It is forced to separate from 5). As shown in FIG. 13, the guide plate (31) has a hole (86) through which the support material (30) passes, and the upper surface (87) of the guide plate has an iron ring attracted to the magnet (85). (88) is buried, and the other portion is made of a material such as synthetic resin, ceramic, etc., which has abrasion resistance against running of the yarn. In addition, the bobbin (60a) (6
0b) is made of a material such as plastic or paper.

Next, with respect to the operation of the yarn feeding / exchange device, FIGS.
This will be described with reference to the drawings and FIGS. 14 to 16.

In the following description, the positions (P1) to (P8) indicate the vertical positions of the receiving material (34), and the positions (P1) to (P8) in FIGS. 14 to 16 are shown in FIGS. 8 Positions (P1) to (P8)
The position (P1) is the highest position and the position (P8) is the lowest position.

First, in the layouts of FIGS. 3 and 4, the idle yarn (10) is stopped and positioned at the exchange station (25).

The yarn supplying / exchanging operation is composed of three steps. That is, it comprises a first step of removing the empty bobbin on the tray, a second step of inserting the lower package into the support material (34), and a third step of inserting the upper package.

FIG. 14 shows the first step. That is, the receiving member (34) turns 90 degrees from the standby position of height (P4) (a1) and grips the upper empty bobbin (60b). Next, it is raised (a2) to the height (P2), the empty bobbin (60b) is pulled out from the support material (30), inverted 90 ° again (a3), and lowered (a4) to the lowest position (P8). As shown in Fig. 11, there is a cam piece (74) at the lowermost position, and since the pressing piece (71) is released, the empty bobbin (60b) that has been gripped falls, and the lower box (Fig. 3 (Fig. 3 ( 1
3)) is housed inside. During this time, after a stop (a5) for a time (t1), the support material (34) rises (a6) to the height (P6) and then turns 90 ° (a7) to grip the lower empty bobbin (60a). Then, when it is raised to the highest position (a8), the intermediate guide plate (31) and the lower empty bobbin (60a) are integrally removed, and when it is raised to the highest position as shown in FIG. 7, the guide plate (31a) Is attracted to the magnet (85). Time (t1)
After stopping (a9), the receiver (34) descends to the P2 position (a1
0), after separating the guide plate (31a) and the empty bobbin (60a), reverse 90 ° (a11) and descend (a8) to the lowest position (P8).
12) Then, by the same operation as above, the empty bobbin (60a) is dropped and stored in the box (13). Stop at time (t1) (a1
3) The backing material (34) rises to the highest position (P1) again (a
14) Then receive the new package from the winder during the reception.

Next, in FIG. 15 of the second step, the receiving material (34) which has received the package to be inserted in the lower stage at the P1 position descends (b1) to the P3 position, then swivels (b2), and moves above the tray. Stop (b2) for a time (t2) at the package insertion position. The guide rod (77) shown in FIG. 6 descends (b4) within this time (t2).
Then, the lower end of the guide rod (77) slightly moves into the support member (30), and takes the position indicated by the alternate long and two short dashes line (77a) in FIG. At this time, the guide rod (77) penetrates the center hole (89) of the waiting package (12a1) shown in FIG. 8 and descends, so that the center hole (89) of the package and the supporting member (30) are the same. The position is corrected on the axis. Therefore, the receiving material (34) then descends (b5) to the position (P7), and the lower package (12a2) is located at the position shown in FIG. When the receiving material (34) is inverted (b6), the package (12a2) and the receiving material (34) are separated, and the package (12a2) inserted into the supporting material falls to the lowermost stage (12a) by its own weight. Of. When the guide rod (77) descends (b4), the guide plate (31a) attracted to the magnet (85) is forcibly pushed downward by the flange portion (81) of the guide rod (the magnet (85)). 85) and slide down along the cylindrical part (82) of the guide rod (77), and the package (12
It is placed on the upper edge of a1). In this state, the receiving material (3
By lowering (b5) of 4), as shown in FIG. 7, the intermediate guide plate (31b) can be mounted on the upper side of the lower package (12a2).

The receiving material (34) is inverted (b6), then raised to the highest position (b7), and the lower package supply is completed.

Next, when the package to be inserted in the upper stage is supplied from the winder side to the receiving material (34) at the P1 position, the third step shown in FIG. 16 is started. The receiving material (34) that received the package at the P1 position descends (c1) to the P3 position, turns (c2), and then stops (c3) for the time (t2) at the two-dot chain line position in FIG.
To do. During this time (t2), the guide rod (77) descends (c4) as in the second step, and the axis of the package on the receiving material is adjusted. Next, the receiving material (34) descends (c5) to the P5 position in FIG. 8, then reverses (c6) and rises (c7) to the standby position (P4) to complete the third step. The upper package (12b2) in FIG. 8 slides down along the supporting material (30) when the receiving material (34) is inverted, and is placed on the guide plate (31). The thread (9) is assembled. In addition,
In the above explanation, the time (t
1) (t2) is appropriately set and is, for example, t1 = 0.5 seconds, t2 = 1 second.

As described above, the yarn feeding station (2
In step 5), the two-stage yarn feeding is replaced, moved in the direction of the arrow (90), and once reserved (91), it is cut out so that the yarn feeding interval on the conveyor (21) is almost constant. Of. The yarn supply that circulates around the double twisting machine is replaced by the empty yarn supply of the spindle by the doffing carriage.

In the two-stage double-twisting machine, the tension applied to the yarn drawn from the lower package is higher than that of the upper package, and the lower yarn tends to be extended. If the packages have the same amount of yarn, the lower yarn may remain even after the upper yarn has been unraveled. Therefore, in order to reduce the remaining yarn amount, it is necessary to supply a package having a slightly smaller yarn amount in the lower stage than in the upper package. Therefore, on the winder (1) side, packages (12
It is desirable to carry a) (12b) as one set to the exchange side. That is, the doffing device is controlled so that the two kinds of packages are alternately and sequentially placed on the conveyor (6) shown in FIG.

〔The invention's effect〕

As described above, in the present invention, the automatic winder and the double twisting machine are connected to each other, and the package doffed by the winder can be directly supplied to the double twisting machine, so that the yarn replacing operation in the double twisting machine is efficient. I can do it. Also, a conveying path for transferring the yarn supply package is laid in a closed loop around the double twisting machine,
Moreover, since the yarn feeder is installed between the winder and the double twisting machine, the winder's production amount is reduced even if the winder, which has a larger production amount than the double twisting machine, is connected to the double twisting machine. There is nothing to do. That is, since the conveying path provided around the double twisting machine serves as a storage portion of the yarn supply package sent from the winder, the winder can produce the yarn supply package without being affected by the production amount of the double twisting machine. You can Moreover, since it is not necessary to provide a storage portion for the yarn supply package between the winder and the double twisting machine, it is possible to save space. Further, since the double twisting machine has a large number of weights and is large as compared with the winder, it is possible to sufficiently secure the length of the conveying path. Further, since the yarn supplying package conveying path is provided in a closed loop shape around the double twisting machine and the yarn supplying package is circulated in the conveying path, an empty yarn supplying yarn and a yarn supplying package are provided for a fully wound spindle. The replacement work can be done easily. Furthermore, by providing a transport path branched from the transport path circulating around the double twisting machine,
By bypassing the yarn supply exchange station, the fully-wound yarn supply can be smoothly performed without delaying the conveying operation of the yarn supply package in the closed loop.
