Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bobbin conveying device in a spinning machine such as a ring spinning machine and a ring twisting machine.

[0002]

2. Description of the Related Art In this type of spinning machine, an empty bobbin is supplied to a front surface of the spinning machine in a state corresponding to a spindle pitch in order to facilitate an automatic refilling operation by a refilling device at the time of a refilling operation accompanied by full filling. A transport device for discharging the doffed full bobbin is required. In addition, a spinning winder in which a spinning machine and a winder are connected by a conveyor device to directly transport empty bobbins and full bobbins between the spinning machine and the winder has been proposed and implemented. There has been proposed a spinning winder in which a full bobbin and an empty bobbin are transported by using a peg tray having a peg protruding from an upper surface thereof (for example, Japanese Utility Model Laid-Open No. 50-50665, Japanese Patent Application Laid-Open No. Hei 1-314737).
No.).

[0003] In some cases, the heat-set yarn is subjected to heat setting after spinning. When heat-setting the yarn, it is preferable to heat-set the yarn before rewinding it with a winder. In that case, the spinning machine and the winder cannot be directly connected,
It is necessary to provide a steam setter (yarn steaming device) for performing heat setting between the spinning machine and the winder. For example, Japanese Patent Publication No. Hei 7-26265 proposes a device in which a yarn steaming device is provided between a spinning machine and a winder, and a full bobbin subjected to heat setting is supplied to the winder. In this apparatus, a full bobbin doffed on a peg protruding from a belt conveyor is guided to a yarn steaming device by movement of the belt conveyor, and is subjected to steam processing (steam set) while being mounted on the peg. Then, the full bobbin subjected to the steam treatment is temporarily stored in the cup storage and then supplied to the winder.

[0004] In the case of cotton spinning, dyed yarn is not spun at the stage of spinning, whereas in the case of wool spinning, yarn dyed is spun. When a multi-product small-lot production is performed, yarns of the same count and different colors may be simultaneously spun by one spinning machine. In this case, yarns of different colors are spun on both left and right sides of the spinning frame. Then, the full bobbin sent to the winder is rewound by a winder unit that rewound a thread of a corresponding color. However, in the spinning winder, in which the full bobbin doffed by the spinning machine is conveyed to the winder using a peg tray, the full bobbin doffed by the spinning machine is transferred to the left and right sides of the spinning frame. It is only carried out from one side of the device. Therefore, when the yarns of two colors A and B are simultaneously spun out, when the full bobbin is carried out, after the carrying out of the full bobbin of the yarn of one color (for example, A) is completed, the full bobbin of the yarn of the other color (B) is completed. Is started.

As a result, of the winder units that perform rewinding corresponding to the respective colors A and B on the winder side,
The operation of the winder unit corresponding to the yarn of color B to be carried out later is stopped in the first half, and the operation of the winder unit corresponding to the yarn of color A is not operated in the latter half. Therefore, the operating rate of the entire winder decreases. Further, the same inconvenience occurs in a system in which a heat setter is provided between the spinning machine and the winder.

Further, in the apparatus for transporting a bobbin using the peg tray, an empty bobbin is mounted on a peg tray which is not arranged at a position corresponding to the spindle during doffing. Therefore, when the full bobbin doffed by this transporting device is transported to the heat setter, the empty bobbin is also subjected to steam processing in the heat setter,
Waste of energy. Also, in the case where the bobbin is directly supplied to the winder without performing the heat setting, the peg tray on which the empty bobbin is mounted is sent to the winder, so that there is a problem that it takes time to select the full bobbin and the empty bobbin in the winder.

In order to solve the above-mentioned problems, it is conceivable to provide a transfer device on each side along the longitudinal direction of the spinning machine table so as to form a closed loop. With this configuration of the transfer device, both transfer devices can independently carry the doffed full bobbins.

[0008]

As a peg tray transfer device, for example, a peg tray using a transfer rail, a guide cover and a positioning member as disclosed in Japanese Patent Application Laid-Open No. 63-275727 is intermittently moved by a predetermined amount. Transfer devices are known. In this prior art, transfer rails provided on both sides of a spinning frame are reciprocated by a pair of air cylinders. It is also known to provide an empty area for one peg tray in the arrangement of the peg trays in order to prevent the peg tray from being twisted due to a shift in the operation timing of the air cylinder.

However, when the above-described transfer device is applied to a transfer device having a closed-loop transfer device on both sides of the machine, a pair of transfer devices are provided on both sides of the machine in consideration of the driving load of the air cylinder. It is desirable to dispose the air cylinder. However, if the transfer and positioning of one peg tray are performed by one air cylinder, and then the transfer and positioning of the opposite peg tray are performed by the other air cylinder, a considerable number of peg trays are transferred. Takes time. The machine cannot perform the next doffing until the transfer of the peg tray is completed. Even if the machine can be doffed during the transfer of the peg tray, the machine must stop and stand by.
If the machine has a large number of weights, the standstill time until the transfer is completed increases, and the operating efficiency of the machine decreases.

If the pair of air cylinders of the transfer device constituting the closed loop are simultaneously driven in the transfer direction and the positioning direction, the time required for transfer is reduced, but in this case, the empty area is also reduced with the transfer of the peg tray. Will move. In particular, if the vacant area moves to the pipe change position, there arises a problem that an empty bobbin runs short at the time of pipe change.

After the supply of the empty bobbins E corresponding to the number of the spindles 7 is completed, when the peg tray 4 to which the empty bobbins E are mounted is arranged at a position corresponding to the spindle 7, a series of full bobbin unloading and empty bobbin supply are performed. Work is completed. At this time, the outer straight portion 5a
Is in a state where the peg tray 4 is not positioned, but there is no problem because the pipe change is performed only in the inner straight portion 5a.

The full bobbin F heat-set by the heat setter 2 is sent to a winder. Then, the empty bobbin E after the yarn is wound back by the winder is returned to the spinning machine stand 1 side via the empty bobbin returning conveyor 3 and is temporarily stored in the empty bobbin storage unit 10 and then stored in the peg tray 4. Supplied.

This embodiment has the following advantages. (A) In the state where the empty area P is provided in the arrangement of the peg trays 4, the transfer rails 14 on both sides of the transfer devices T1 and T2 are simultaneously driven in one transfer direction and the other in the positioning direction. This prevents twisting and prevents the empty area P from moving to the pipe change position. Further, the transfer and positioning of the peg tray 4 and the dummy tray D can be simultaneously performed on the transfer devices T1 and T2, and the required transfer time is shortened and the operation rate of the machine is improved.

(B) Since the reciprocating movement of the transfer rails 14 on both sides of the transfer devices T1 and T2 are performed simultaneously in the same direction, the air cylinder 17 for reciprocating the transfer rails 14 is used.
20 to 20 are the same, the immersion and projection operations of the piston rods 17a to 20a are the same, driving control becomes easy, and a control system such as an air valve can be shared.

(C) Transfer and positioning of the full bobbin F and the empty bobbin E via the peg tray 4 moving in the peg tray passage 5 provided on each of the right and left sides of the spinning frame stand 1 so as to form a closed loop independently. Is performed. Accordingly, the positioning of the peg tray 4 at a position corresponding to the spindle 7 is simplified as compared with the case where a belt conveyor is used. Further, the positioning accuracy is maintained in the initial state even after long-term use, and the durability is improved.

(D) Since each peg tray path 5 extends from the out-end OE to the outside of the spinning frame 1, the full bobbin F on the peg tray path 5 is transferred to the transfer device in the next step. Becomes easier.

(E) Linear portion 5 constituting positioning area
a is extended to a position corresponding to the bobbin transfer device 8, the peg tray 4 can be simultaneously positioned at a position corresponding to the spindle 7 and a position corresponding to the bobbin transfer device 8, and the full bobbin by the bobbin transfer device 8 is provided. Delivery of F to the heat setter 2 becomes easy.

(H) The heat set by the heat setter 2 requires a predetermined time, and the heat set of the full bobbin F delivered from each of the transfer devices T1 and T2 is reduced by one.
When performing in a row state (two rows in total on the left and right sides), the time required to arrange the peg trays 4 for one row at a position corresponding to the bobbin transfer device 8 and to transfer the peg trays 4 to the full bobbin transfer device by the bobbin transfer device 8. However, the time required for heat setting is much shorter. As a result, the waiting time becomes longer and it takes time to complete the unloading of the full bobbin F from the peg tray passage 5, and the empty bobbin E cannot be prepared at the position corresponding to the spindle 7 before the next full stoppage. After stopping, there is a problem that the waiting time until the start of doffing becomes long.

However, in this embodiment, since the heat setting is performed simultaneously for each of a plurality of rows, the time required for the heat setting is effectively used as the time for transferring the full bobbin F from the peg tray 4 to the full bobbin transfer device by the bobbin transfer device 8. Available. As a result, the empty bobbin E can be prepared at a position corresponding to the spindle 7 with a margin before the next full filling stop.

(I) In parallel with the unloading of the full bobbin F, the empty bobbin E is placed on the peg tray 4 from the empty bobbin supply device 9 arranged on the gear end GE side of the peg tray passage 5 (opposite to the full bobbin unloading side). Is supplied, the time required for carrying out the full bobbin F and completing the preparation of the empty bobbin E is reduced.

(G) Since the end portion of the base plate 23 constituting the connecting portion 5b is extended to form the supporting portion 23a for supporting the peg tray 4, the production and assembly are performed in comparison with the case where the supporting portion 23a is provided separately. It becomes easy to attach.

After being transported into the heat setter by T1, T2, and subjected to steam treatment and carried out of the heat setter, it is extracted from the peg tray 4 and sent to the winder. In this case, since a part of the transfer devices T1 and T2 are disposed in the heat setter, they undergo steam processing. However, unlike the transfer device of the belt conveyor type, there is no fear that the positioning accuracy is reduced due to the expansion and contraction of the belt.

(4) Engagement projection 14a of transfer rail 14
Is not always necessary, and the engagement projections 14a may be omitted or one peg tray 4 may be provided.

(5) Peg trays 4 are mounted in one row as transfer devices T1 and T2, and transfer rail 1 reciprocates.
Instead of the apparatus using the Peg 4, the peg tray passage 5 is constituted by a guide plate which is fixed at a predetermined position and slidably supports the peg tray 4, and the linear portion 5a is provided with a straight line 5a.
It is also possible to provide a feeding device configured to reciprocate a rod provided with a locking claw by an air cylinder as in the device disclosed in JP-A-161133. In this case, the rod provided with the locking claw and the air cylinder constitute the transfer means.

The transfer rail 14 may be supported via a ball bearing in the same manner as the apparatus disclosed in Japanese Patent No. 184839.

(7) The present invention is not limited to the ring spinning machine, but may be applied to a ring twisting machine. (8) The free area P may be two or more as long as it is an integral multiple of the size of the peg tray 4. However, at this time, it is necessary to adjust the stroke of the piston rods 17a to 20a to the size of the empty area P.

(9) Instead of the air cylinder, the transfer rail 14 may be reciprocated by a hydraulic cylinder or a crank mechanism. (10) Only the peg tray 4 may be used without using the dummy tray D. At this time, it is preferable to control the empty bobbin supply device 9 so as to supply only a necessary number of empty bobbins.

(11) As shown in FIG. 10, the peg tray passage 5 may be formed in a substantially U-shape with the carry-out side opened. At this time, the collection unit 28 and the supply unit 29 of the peg tray 4 connected to the next step are connected to the open side, respectively.
