Specifically, the present invention has been made in order to solve the above-mentioned various disadvantages. is provided with a passage for receiving carriers from the transport conveyor, and the carriers are positioned at a predetermined position in the passage, and when a predetermined number of carriers are stored in the passage, the carriers on the pipe supply conveyor are transferred to the unit. The magazine is not supplied but is passed through and supplied to the next unit, thereby providing a novel and extremely simple structure device to replace the above-mentioned magazine.

Embodiments of the apparatus of the present invention will be described below with reference to the drawings.

Fig. 1 shows a winding unit to which the device of the present invention is applied, in which a spindle 2 and a suction pipe 3 are installed between each side frame 1, and a winding unit 4 is rotatable on the spindle 2. While the automatic winder is in operation, the unit 4 is also placed on the suction pipe 3 and fixed appropriately. Note that the suction pipe 3 is connected to a blower (not shown), and a suction air current is constantly applied thereto.

In winding the yarn from the tube yarn 5 to the package 6 in the winding unit, the yarn pulled out from the tube yarn 5 on the carrier 7 passes through the balloon breaker 8 and the yarn guide 9, and then is given an appropriate tension by the tensor 10. It passes through a slab catcher 11 and is wound onto a rotating package 6 by a winding drum 12.

At this time, when the slab catcher 11 detects a slab in the yarn, a cutter installed near the slab catcher 11 operates to cut the running yarn Y, and while winding is stopped, the first The thread arm 13 operates and moves the thread on the package cage 6 side to the second thread.

That is, first and second guide plates 30 and 31 are fixed to the unit machine base to form a passage for the carrier 19 between the pipe supply belt 16 and the empty wood pipe discharge belt 17. That is, a first passage 34 having a width S is formed by the concave curved guide surface 32 of the first guide plate 30 and the convex curved guide surface 33 of the second guide plate 31, and the lower surface of the passage is formed by a freely rotating disk 35. The carrier 19 is mounted on the conveyor 1 on the disc 35.
6 and the carrier 19 is transferred along the passage 34 by rotation of the disc in the direction of the arrow 36. The length of the first passage 34 is such that when a predetermined number of carriers are stored in the passage, the end of the rearmost carrier 19C is the end 16a of the conveyor belt 16.
The length is such that

The disk 35 is pivoted 37 on a bracket 36 fixed to the side surface of the unit 4, and the shaft 37 is fixed at a slight inclination with respect to the horizontal plane. 19 is inclined with respect to the vertical line by the inclination angle of the axis 37. That is, the central axis of the pipe yarn 5 on the carrier 19 is inclined in the direction of unwinding the yarn to improve unwinding performance. Further, the curved guide surfaces 32 and 34 of the first and second guide plates 30 and 31 end at the yarn pull-out position P, and the guide surface 40 that forms the empty wooden tube discharge passage 3a of the same width S continues. ,4
1 is formed on each guide plate 30,31. The lower surface of the above discharge passage is a flat plate 4 fixed to a bracket.
2 is tilted and fixed so as to form the same plane as the upper surface of the disk 35. A gap 43 is formed between the disk 35 and the flat plate 42, which serves as a thread pull-out position for the tube yarn, and serves as a passage for air ejected from the air ejection nozzle 28 disposed below.

Further, the disk 35 has an annular band portion 46 formed by an outer circumference 44 and an imaginary circular arc 45 spaced a certain distance l from the outer circumference, so that it comes into pressure contact with the side upper surface of the conveyor belt 16 when the disk rotates. The disk 3 is moved by the running force of the conveyor belt 16.
5 rotates, so that the conveyor belt 16 not only conveys the tube yarn but also functions as a driving source for the disc 35.

Further, at each unit position of the conveyor belt 16, a third
A guide plate 47 is fixed. The guide plate 47 is fixed so as to protrude from the side of the conveyor to the center of the conveyor with a separation of at least the thickness t of the base body 20 of the carrier 19 between the conveyor 16 surfaces, and is fixed to the linear guide surface 48 and the guide surface. A curved guide surface 49 following 48 forms a second passage 51 together with the opposing guide surface 50 of the second guide plate 31 .

Furthermore, the guide surface 52 of the third guide plate 47 and the guide surface 30a of the first guide plate 30
After the passage 70 has been constructed and a predetermined amount of pipe yarn has been stored in the first passage 34, the end of the rearmost carrier in the first passage is tilted to the conveyor belt 16.
, the carrier of the tube yarn that is further conveyed is blocked from entering by the rearmost carrier in the passage 34 and is pushed by the following carrier, or the undersurface area of the carrier is large toward the conveyor belt 16 side. By taking the position where , the yarn is conveyed through the third passage 70 in the direction of arrow 67, and is supplied to the same pipe supply device as described above provided in the next unit.

Note that the width S of each of the passages 51, 34, 39, and 70 is regulated to be slightly larger than the diameter d of the base portion 21 of the carrier 19, and the height h is regulated to be slightly larger than the thickness t of the base 20 of the carrier 19. be done.

Reference numeral 53 denotes a pivot lever for positioning and discharging the tube yarn, which is supported pivotally on the fixed plate 42.
It rotates between the two-dot chain line position 53a and the solid line position 53 in the figure. The shaft 54 of the lever 53 is also the shaft 3 of the disc 35.
The guide surface 55 of the lever 53 is inclined at the same angle as 7,
56 and 57 rotate in a plane parallel to the disk 35 and come into contact with the platform 21 of the carrier 19. Lever 5 above
When the hook portion 58 of No. 3 is in the solid line position, it projects into the passage 34 and comes into contact with the stand portion 21 of the carrier 19 to position the pipe yarn. Guide surface 55 of the hook portion 58
The curved guide surface 56 following the carrier 1 at the winding position
9 along the extrusion path 39, and a guide surface 57, which is a part of an arc centered on the shaft 54, is used to insert the next new tube yarn when the carrier at the winding position is discharged. This is a guide surface for preventing the carrier 19a from being transferred.

The lever 53 is driven by the lever 59 shown in FIG. 3 being actuated via a rod (not shown) which is actuated by a new yarn supply command from the winding unit, and the shaft 42 being rotated via a connecting rod 60. It will be done.

Furthermore, a balloon guide 61 that can pivot freely above the lever 53 is supported by a shaft 62. The balloon guide 61 has a curved plate 64 fixed to the tip of an arm 63, and is biased by a spring 65 in the clockwise direction in FIG. 2, so that the balloon guide 61 moves as shown in FIG. It is positioned at the position indicated by the solid line in FIG. 3, so that the balloon of the drawn-out yarn of the yarn tube 5 does not come into contact with the next yarn tube waiting in the passageway 34. The balloon guide 61 is positioned by the side surface of the spring-biased arm 63 coming into contact with a stopper 66 at the end of the yarn discharge lever 53. Therefore, when the lever 53 turns to a position 53a shown in two-dot chain line in the third figure, the balloon guide 61 follows the turning of the lever 53 and turns clockwise around the shaft 62, that is, the arm 63
rotates to a position where it abuts the stopper 66a at the two-dot chain line position, the curved plate 64 retreats from above the passage 34,
The carrier 19a with the new yarn inserted is at the yarn supply position P.
will be transferred to.

In the above-mentioned pipe supply device, the spun pipe 5a is inserted into the carrier 19 which is transferred on the conveyor belt 16, and the pipe thread 5a after spinning is inserted into the carrier 19 which is transferred on the conveyor belt 16. When it comes into contact with the guide 47, the carrier 19 is transferred along the second path 51 and the bottom surface of the base is transferred onto the disk 35, and as the disk 35 rotates in the direction of the arrow 36,
The carrier 19 is transported along the first passage 34 and is stopped by engaging a hook 58 at a bend in the first passage. In this way, when a predetermined amount (three in FIG. 2) of carriers 19 having pipe yarns transferred on the conveyor belt 16 in the direction of the arrow 67 are stored, subsequent carriers pass through the first path 51 to the carrier 1.
The carrier 19e at the entrance of the first passage 34 is prevented from coming into contact with the base 20c of the belt 19, and the contact surface with the belt 16 is large, so a large frictional force acts, and the carrier 19e at the entrance of the first passage 34 moves inside the third passage 70 along the guide surface 52. It is transferred by the advancing conveyor belt 16 to the next winding unit. Therefore, if the conveyor belt 16 is allowed to circulate, a predetermined number of yarns will be supplied to all units.

The process of pulling out the yarn from the tube yarn 5 positioned at the fixed position in FIG. 1 and starting winding is performed roughly in the following order. That is, an air jet nozzle 28 is arranged below the carrier 7 at a fixed position, and the air jet nozzle 28
As mentioned above, the air ejected from 8 is ejected from the hole drilled in the peg of the carrier to the center hole of the wood tube 26 of the tube yarn, blowing the yarn end Y1 hanging down inside the wood tube center hole 27 into an upper cylindrical shape. The upper end of the yarn end is blown up through the balloon breaker 8. On the other hand, from the winding unit side, the second suction arm 14 is located near the two-dot chain line position 14a in FIG.
The suction arm 14a sucks and holds the yarn end blown up through the balloon breaker 8. Suction arm 14 sucking the side yarn end of the tube yarn
rotates counterclockwise around the shaft 67, and attracts and holds the yarn end on the package cage 6 side.
The suction arm 13a rotates clockwise around the shaft 68, the ends of the yarn are crossed and introduced into the knotter 15, the yarn is tied, and then normal winding is started.

When there is no yarn left in the tube yarn at the yarn supply position, the detection device on the unit side is activated, issues a command to discharge the empty wood tube, and operates the discharge lever 53 actuating rod 60 shown in the third figure.
is actuated, the ejection lever 53 turns to the position 53a shown in two-dot chain line in the second figure, and the carrier 1 having the empty wood pipe is
9f is discharged onto the conveyor belt 17 for empty wood pipe transfer as shown in the first figure, and as the discharge lever 53 returns to its original position, the carrier 19a carrying the next new pipe yarn moves along the path 34, and the predetermined yarn supply is completed. It is positioned to position P.

As described above, in the present invention, when a predetermined number of pipes that are set on an independent carrier and transferred on a pipe supply conveyor belt are stored in the passage provided in the winding unit, the following pipe threads are transferred. The magazine provided in each unit was used because a tube supply device was installed in which the carriers stored in the passage were prevented from entering at the rear end and were automatically discharged onto the conveyor belt. The yarn can be stored without any trouble, and to supply new yarn to the yarn supply device, it is only necessary to move the carrier in parallel within the passage for one pitch, and the yarn can be fed to the yarn supply position extremely quickly and accurately. It is possible to send Further, since the device for transferring the carrier from the transport conveyor to the yarn supplying device is composed of a rotating plate and a guide plate with a passage formed on the disk, the tube yarn can be supplied with an extremely simple device. By supplying a carrier on which the pipe yarn is planted on the conveyor belt, a predetermined amount of the pipe yarn is automatically stored in the first passage of each winding unit.

Furthermore, there is no need for a sensor to detect the presence or absence of the yarn in the passage, or an actuator for taking in the yarn on the conveyance path based on the signal from the sensor, making the yarn conveyance and supply device extremely simple. This is possible with mechanical components that do not require an electrical control device, eliminates complicated electrical wiring, and eliminates errors in detecting the yarn due to sensor malfunction.
