Description

[Detailed Description of the Invention] [Industrial Application Field] In a case where the pipe yarn produced by a ring spinning machine or a ring twisting machine in the spinning process is randomly stored in a storage box, the stored pipe yarn is This system allows the yarns that are randomly thrown into the hopper to be fed into the process to be lined up in a row in the axial direction and taken out one after another, and can be used for handling yarns in the textile industry.

[Prior Art] Tube yarn produced by a ring spinning machine or a ring twisting machine is generally temporarily stored in a storage box for handling. By the way, when storing the tube yarns in this storage box, an automatic tube changer equipped with a tube processing device can store the tube yarns in an orderly arrangement in the storage box, but it is not possible to manually change the tubes or to store the tube yarns in the storage box. In an automatic tube changing device that is not equipped with a yarn processing device, the doffed tube yarn is stored in a storage box in a disorderly manner. On the other hand, in order to automatically supply these stored pipe yarns to an automatic rewinding machine or processing device, it is necessary to take out the pipe yarns one by one, and as a means to do so, the pipe yarns in the storage box are fed into a hopper or the like and one by one they are taken out. A device for aligning and taking out the materials has been developed and put into practical use. These take-out devices include a vibrating conveyor connected to the bottom or outer periphery of the hopper to align the tubes in the axial direction and take them out in a row, or an umbrella-shaped rotating conveyor on the bottom of the hopper. There is known a device that is configured with a disk and in which the stored tube yarns are sequentially taken out from the outer circumferential side of the rotary disk while being aligned in the axial direction. However, it has been pointed out that these pipe removal devices have disadvantages such as being large-sized and increasing the installation area, or causing the pipe threads to move or roll unnecessarily, thereby causing the end threads of the pipe threads to be unraveled.

[Problems to be Solved by the Invention] Therefore, the present invention aims to provide a device that takes out the yarns thrown into the hopper in a small area, aligning them in the axial direction without swinging them around too much. It is something to do.

[Means for solving the problem] That is, in the present invention, the bottom surface of the yarn storage hopper is
The belt conveyor device is composed of a belt conveyor device inclined on one side, and the belt conveyor device is a double conveyor with a wide conveyor on the upper side of the slope and a narrow conveyor with a width almost equal to the outer diameter of the pipe yarn on the lower side of the slope. The narrow conveyor is rotated constantly or intermittently in the reciprocating direction in the direction of taking out the pipe yarn, and the wide conveyor is rotated constantly or intermittently to remove the bridging pipe yarn groups while being taken out by the narrow conveyor. It is.

[Operation] The pipe yarns randomly charged and stored in the pipe yarn storage hopper fall down in an inclined direction by a double conveyor consisting of a wide conveyor and a narrow conveyor, which are arranged at an angle on the bottom side of the hopper. At the same time, the pipe threads are sequentially lined up in the axial direction and taken out by the narrow width conveyor for taking out the pipe threads at the lower part of the slope. By intermittently driving the conveyor in the opposite direction to the narrow conveyor or in the circumferential direction, the cross-linked state is broken and the pipe threads are sequentially taken out by the narrow conveyor.

[Example] The present invention will be described in detail below based on the drawings, but the drawings show a specific example of implementation, and the present invention is not limited to the illustrated example. The same implementation is possible even if a part of the configuration or design is changed. FIG. 1 (side view) shows an example of the use of the pipe thread take-out device 1 according to the present invention. Although the pipe thread take-out device 1 can be used alone,
It is preferable that it be installed in conjunction with the tube input device 2. Although any suitable conventionally known device can be used as the yarn feeding device 2, the figure shows a pulling device 2a that receives and pulls up the yarn storage box 3, and a lifting device 2a that receives and pulls up the yarn storage box 3, and a lifting device 2a that overturns the yarn storage box that has been pulled up above it and stores the yarn storage box 3. A lifting platform 2c provided on the lifting device 2a so as to be freely raised and lowered receives the pipe and yarn storage box 3 and rises, and when it reaches the overturning device 2b, other actuating devices The storage box 3 is overturned by the above mechanism, and the stored pipe yarn is thrown into the hopper of the pipe take-out device 1. Incidentally, in this overturning charging, the charging is regulated according to the amount of accumulation and storage in the hopper, and the charging amount is adjusted by detection by a level sensor, which will be described later. 2b is a falling actuation device, which is connected to the lifting device 2a.
d and 2e are receiving guide rails for the yarn storage box 3;
This is the discharge guide rail for the empty tube storage box.

On the other hand, the tube take-out device 1 is constructed as shown in FIG. 2 (plan view) and FIG. 3 (left side view in FIG. 1). That is, the pipe thread take-out device 1 is constructed by combining a main body portion 1a and a hopper portion 1b above the main body portion 1a,
The hopper portion 1b is formed by the side walls 4, 4a, the front wall 5a and the rear wall 5 with upper edges of approximately the same height,
A projecting wall 1c is erected on the upper part of the front wall 5a. Although this projecting wall 1c can be removed if necessary, it is effective for guiding the pipe yarn dropped from the overturning device 2b into the hopper as shown in FIG. An inclined plate 6 is provided on the inside of the front wall 5a, and a guide plate 7 is provided on the inside of the rear wall 5.
7a may be an auxiliary guide and may be omitted. The inclined plate 6 and the guide plate 7 are opened at their inner tip edges with a gap wider than the axial length of the yarn, and are inclined in the same direction as the inclined plate 6 so as to cover the opening. A double belt conveyor system will be installed. The double belt conveyor device has a wide conveyor 10 with a wide width on the upper side of the slope and a narrow conveyor 11 with a narrow width on the lower side of the slope. It is preferable that the width is approximately the same as the outer diameter of the tube. As shown in FIG. 5 (a partially enlarged view of FIG. 1) and FIG. The suspension pulleys 10b and 11b (FIG. 3) on the other side are also supported in the same way. And these pulleys 10a, 11a, 10b, 1
1b are shafts 14 supported by the brackets, respectively.
Driven pulleys, which are freely supported through ball bearings and integrally formed on both ends of drive pulleys 10a and 11a, are driven by belts 15 and 15a, and these belts 15 and 15a are shown in FIG. As shown, they are individually driven by motors 16 and 16a provided within the main body portion 1a. As shown in FIG. 2, the belts 10 and 11 are driven by driving the narrow conveyor belt 11 constantly or intermittently in the direction of the arrow D or C, so that the tube yarn is axially placed on the belt 11. When the narrow belt 11 moves in the direction of arrow C, the pipe yarn is transferred to a discharge conveyor 12, which will be described later. On the other hand, the wide conveyor belt 10 is constantly or intermittently driven in the direction of arrow A or B to break up the group of yarns.
The tube yarn is moved so as to be placed on the narrow belt 11.

An inclined guide plate 8 is provided inside the other side wall 4, and a guide plate 9 is also provided inside the other side wall 4a.
The tip side of the guide plate 9 is a curved rocking plate 9a, and the tip side thereof is elastically provided so as to maintain a distance from the side wall 4a, and a limit switch 18 is provided at the position where the tip side contacts the side wall. . A yarn outlet 4b (FIG. 1) is formed in the side wall 4a at a position opposite to the narrow conveyor belt 11, and a discharge conveyor 12 is provided on the outside of the side wall 4a via brackets 13, 13a. This discharge conveyor 12 is driven by a single motor (not shown), and has a width that enables discharge and conveyance of one pipe yarn. Although not shown, it is recommended that the double conveyor belts 10 and 11 be provided with individual or common support plates inside. Reference numeral 17 indicates a level sensor for the yarn deposited in the hopper portion 1a, which regulates the amount of yarn input by the yarn input device 2, and is shown attached to the top of the side wall 4 in the figure, but it can be installed at any other suitable location. It may be attached to.

[Effects of the Invention] In the yarn take-out device configured in this manner, as shown in FIG. The pipes try to fall to the double conveyor belt side, and the placed pipe threads are transferred from the outlet 4b to the discharge conveyor 12 by driving the narrow conveyor belt 11 in the direction of the arrow. Due to friction, it accompanies the take-out pipe thread, and as shown in the figure, it is directed toward the take-out port 4b side and becomes in a cross-linked state. However, above the narrow conveyor belt 11, the above-mentioned wide conveyor belt 10 is arranged at an angle, and in the cross-linked state, the swing plate 9a of the guide plate 9 operates the limit switch 18. As a result of the operation, the wide conveyor belt 10 moves backward in the direction of the arrow A in FIG. 2, breaking down the cross-linked tube yarn group and causing it to fall toward the narrow conveyor belt 11, as if the tube yarns were lined up on the narrow conveyor belt. Can be transferred. Then, the wide conveyor belt 10 is caused to move back in the B direction again at a certain time via a timer device. Furthermore, due to the crosslinking, the narrow conveyor belt 1
1 may be temporarily stopped or the wide conveyor belt 10 may be moved backward in the direction of arrow D. Regarding these drives, the narrow conveyor belt 11 may be driven intermittently or reversed depending on the amount of yarn to be processed and the type of yarn to be processed, or the reciprocating drive of the wide conveyor belt may be automatically suppressed by a programming device. You may. In the present invention, the bottom side of the pipe yarn storage hopper is constructed with the wide conveyor belt of the double conveyor device tilted in this manner and the narrow conveyor belt for taking out the pipe yarn, so that the crosslinking is performed when taking out the pipe yarn. It is possible to smoothly take out the tube thread in a single file without any trouble. The yarn discharged from the discharge conveyor 12 is conveyed by suitable conveying means to an alignment device or other processing device. Further, according to the present invention, the pipe take-out device can be made smaller and can be easily installed between existing machines, and since the pipe group is not rotated unnecessarily, the sagging of the thread ends can be reduced.
