Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts feeder for aligning and supplying a spinning yarn in order to convey the spinning yarn to the next step for various treatments.

[0002]

2. Description of the Related Art When supplying spinning yarns to a subsequent process such as an automatic winder, a large number of yarns are sequentially aligned in a parts feeder, and the yarns are individually fed to a tray conveyed by a conveyor. It is carried out upright and upright, i.e., while being inserted and conveyed while determining the top end of the yarn.

At this time, the yarns aligned by the parts feeder and conveyed by the conveyor are surely discriminated by a top end discriminating device provided in front of the dropping chute so as to be inserted in the tray. It has been practiced to store the pipe yarn conveyed by the conveyor in a storage portion and send the pipe yarn one by one to the top end determination device. Therefore, when there is no yarn at the specified position in this reservoir, the tray on the conveyor is pushed into the reservoir by the pushing device, and when there is no yarn on the conveyor, the parts feeder is operated to convey one yarn to the conveyor. And then stopped the operation of the parts feeder to prepare for the next operation.

[0004]

In the above apparatus, since the conveyor for conveying the yarn is not operated when the yarn is present in the reservoir, it is impossible to operate the parts feeder to feed the yarn. Therefore, in the parts feeder, the operation time for transporting the yarns to the carry-out port while aligning the yarns is reduced, and when a signal requesting to send the yarns from the parts feeder to the conveyor is received, the yarns cannot be immediately sent out. After operating the parts feeder for a while, one piece of yarn was supplied to the conveyor, so that smooth supply was not performed and the processing capacity of the parts feeder was not improved.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a parts feeder which enables a yarn to be smoothly carried out to the next step and has an improved processing capacity.

[0006]

In order to solve the above-mentioned problems, the present invention provides a shutter which is opened by a yarn thread request signal at a yarn thread discharge port of a parts feeder for discharging yarn while aligning the yarn threads. This is a parts feeder that is equipped with a parts feeder drive control device that drives the parts feeder for a predetermined time when it is closed, thereby making it possible to smoothly carry the yarn out to the next process and improve its processing capacity. .

[0007]

Since the present invention is configured as described above, the yarn threads from the parts feeder are sequentially aligned by driving the parts feeder, and are provided at the discharge port of the parts feeder in response to the yarn thread request signal from the next process. The shutter is opened, and the yarn is carried out one by one. On the other hand, even when there is no yarn thread request signal and the shutter is closed, the parts feeder drive control device drives the parts feeder for a predetermined time to align the yarn threads on the parts feeder, and immediately after the shutter is opened. Prepare to carry out the above yarn.

[0008]

Embodiments of the present invention will be described with reference to the drawings. A spiral passage 2 is continuously provided on the inner peripheral surface of the parts feeder 1 from a central portion to an outlet 3 on the outer periphery. To the bottom of the center. The parts feeder is vibrated by a driving device provided at the lower part thereof, whereby the pipe threads dropped on the central bottom part are conveyed to the carry-out port 3 while being aligned one by one while moving up the spiral upper passage.

A shutter 6 is provided at the carry-out port 3, and the shutter 6 is driven by a solenoid 7 via a link 8.
The tube yarn conveyed in the spiral passage 2 is stopped from coming out to the carry-out port 3, and the releasing operation is performed. A light-receiving element 10 is provided in the vicinity of the carry-out port 3, and the pipe yarns conveyed from the carry-out port to the pipe yarn conveying conveyor 11 provided on the front surface thereof are detected and counted.

The thread transport conveyor 11 is driven by a motor 12, and the thread transferred to this conveyor is dropped into a thread cutting device 13 provided at the end. At this time, the light receiving element 9 detects whether or not the yarn is present at the end of the conveyor 11. The pipe thread cutting device 13 includes a pair of left and right cutting members 16 fixed to a shaft 15 driven by a motor 14.

The yarn thread dropped from the yarn thread conveyer 11 to the yarn thread cutting device 13 is received by the receiving portion of the blade stopped at the uppermost portion, and the fall prevention rod 20 located on the entire surface of this receiving portion 20. Is prevented from falling. At this time, the light receiving element 19 detects whether or not the yarn is present on the receiving portion.

In the fall prevention rod 20, when the motor 14 is driven, the shaft 15 rotates, and the pair of left and right cutting members 16 rotate, so that the cam 27 is interlocked with each other when the pipe thread placed on the blade receiving portion is cut out. The rotation of the drive lever causes the fall prevention rod 20 to oscillate, whereby the tubular thread 5 can be cut out.

[0013] A top end discriminating device 34 is provided on both lower sides of the pipe thread cutting device 13, and when the cutting member 16 is rotated by the drive of the motor 14 to cut out the pipe yarn 5, the thin end portion of the pipe yarn 5 is made. Since the rod 40 or 41 is brought into contact with the rod 40 or 41 and the fall is temporarily stopped, the large-diameter end portion at the other end falls as it is without coming into contact with the rod.
2 becomes downward, the top is discriminated, and it falls into the chute 43.

Below the chute 43, a cylindrical chute guide 44 having an inner diameter slightly larger than that of the yarn 5 is provided, and the front half of the chute guide 44 is the opening / closing portions 45 and 46, and is located behind the chute guide 44. Opening / closing device 4 provided
The rotation of the cam 48 at 7 allows it to be opened and closed via a lever 50. At this time, the light receiving element 49 detects whether or not there is a yarn in the chute guide 44.

A conveyor 52 having a stop position 51 just below the lower end opening of the chute guide 44 conveys an empty tray 53, and in the vicinity of the stop position 51, a tray cutting device 54 inserts a yarn at a predetermined stop position 51. To wait for. The tray cutting device 54 is intermittently driven by a motor 55, and a light receiving element 56 determines whether or not the tray is in the stop position, and a light receiving element 57 determines whether or not the tray cutting device is rotated to a predetermined position. To be detected. Further, in order to carry out batch processing of inserting the six yarns into the tray 53 as one group, a light receiving element 58 is provided above the conveyor corresponding to a position where six trays are retained from the stop position 51.

In the above apparatus, when the light receiving element 56 detects that a tray is present at the stop position 51 of the conveyor 52, and when the light receiving element 58 detects that six trays stay on the conveyor, the tray is moved to the tray. A batch of operations for inserting the thread is started. First, the light receiving element 49 detects that there is no yarn in the chute guide 44,
When the light receiving element 19 detects that there is no thread on the cutout member 16 and the light receiving element 9 detects that there is no thread on the conveyor 11, the solenoid 7 is driven to open the shutter 6, Drive the parts feeder 1.

The height of the yarn thread 5 dropped by the carry-in conveyor 4 on the central bottom of the parts feeder 1 is measured by a light-receiving element 39 provided immediately above the height, and the number of dropped yarn threads is measured. And the drive of the carry-in conveyor 4 is controlled. When a steady state is reached by the series of operations described below, the light-receiving element 10 integrates the yarns carried out from the parts feeder, and when a predetermined amount of yarns are carried out, the carry-in conveyor 4 is driven to drive the yarns to a predetermined amount. It is possible to control so as to throw in a tubing of a degree close to.

By the operation of the parts feeder 1, the yarns 5 which are aligned one by one and are conveyed in the spiral passage 2 pass in front of the shutter 6 which is open, and from the carry-out port 3 to the yarn conveyer 11. Be transferred. At this time, the tubing transferred by the light receiving element 10 is detected and counted. Pipe thread conveyor 1
The yarn above 1 is conveyed by the drive of the motor 12, and is thrown into the receiving portion of the blade of the cutting member 16 located below it at the exit end of this conveyor and received. At this time, the fall prevention rod 20 has the receiving portion 18
Since it is located on the front surface of the pipe, the fall from the receiving portion 18 is prevented, and at that time, the position of the end portion of the yarn is regulated by the end plate 29.

Next, when the shaft 15 is rotated by the drive of the motor 14 and the cutting member 16 is rotated, the tubular yarn 5 is
The blades forcefully cut out and drop onto the chute 43. At that time, the yarn is fast at the top of the heavens discriminating device 34.
Since the small-diameter end of the bobbin comes into contact with the rod 40 at high speed, the impact makes the distinction of the top end clear.

The pipe thread dropped on the chute 43 falls while being guided in the chute guide 44 and is inserted into the peg 59 of the tray 53. Then, the opening / closing unit 45 is opened by the operation of the opening / closing operation device 47, and the tray cutting device 5
By the rotation of 4, the trays fitted to the four cutting grooves 60 provided on the outer periphery of the disk-shaped tray cutting device are fed out, and at the same time, the trays following the cutting groove 60 of the tray cutting device 54 The tray is fitted and conveyed to the tray stop position 51. The opening / closing operation device 47 closes the opening / closing portion 45 by the rotation of the cam 48 which is interlocked with this. The rotation amount of the tray cutting device 54 is detected and controlled by the light receiving element 57. At this time, since the conveyor 52 constantly drives the trays in the feeding direction, subsequent trays are also fed in order.

During the above operation, when the blade of the cutting member 16 rotates by 120 degrees and the succeeding blade comes to the position of the preceding blade, the light receiving element 19 detects that there is no yarn on the receiving portion. Then, the operation of the parts feeder 1 and the conveyor 11 puts the tube yarn on the receiving portion to put it in a standby state for the next operation. At this time, when it is detected by the light receiving element 9 that no yarn is present at the carry-out end portion of the conveyor 11, the shutter 6 of the parts feeder 1 is opened to transfer the yarn on the conveyor 11, and then the yarn on the conveyor 11 is transferred. By the operation, the yarn can be conveyed to the carry-out end portion and can be in a standby state.

When the light receiving element 56 detects that the next tray has been conveyed to the tray stop position and the light receiving element 49 detects that there is no yarn in the chute guide 44, the motor 14 is driven again. Then, the same operation as above is performed to drop the yarn on the chute 43 while determining the tail end of the yarn, and the yarn is inserted into the tray. When it is counted that the light receiving element 10 has carried out six yarns as one batch by repeating the above operation, the solenoid 7 is driven to close the shutter 6 and the yarns from the parts feeder 1 to the conveyor 11 are removed. Stop the transfer. Therefore, thereafter, the work of aligning the yarns on the spiral passage 2 of the parts feeder 1 can be performed without appropriately driving the parts feeder 1 and transferring the parts feeder 1 to the conveyor 11.

When the above series of operations is completed, it waits for six empty trays to stay on the conveyor 52 again, and after the stay, the same operation as above is repeated.

In the above-described series of operations, when each light receiving element detects that no yarn is always present in the next process in each yarn supplying process section, it is necessary to immediately supply the yarn. In particular, it is difficult to smoothly carry out the portion of the parts fed from the parts feeder 1 to the yarn conveying conveyor 11.

That is, the parts feeder 1 drives the parts feeder when the signal for requesting the yarns from the tube yarn conveyer 11 is input to the parts feeder drive control device, and the spiral passage 2 is raised by the vibration thereof. The yarn passes through the open shutter 6 and is transferred from the carry-out port to the pipe yarn transporting conveyor 11. When the pipe yarn is transported to the pipe yarn transporting conveyor, it is detected and the shutter 6 is released. Is closed and the parts feeder drive device is stopped, so that the succeeding tubing 5 is not always conveyed to immediately before the shutter 6.

Therefore, when the parts feeder is stopped while the succeeding yarn is conveyed to a position just before the shutter 6 on the spiral path 2, a yarn request signal is sent from the yarn conveyer 11 next. Even if the parts feeder is driven when there is such a time, it takes a long time for the yarn to reach the carry-out port of the parts feeder. As a result, in the above-mentioned series of yarn feeding processes, it is necessary to wait until the yarn is carried out from the parts feeder, and smooth yarn feeding may not be possible.

Therefore, in the present invention, after the yarn is transferred from the parts feeder 1 to the yarn conveying conveyor 11 and the shutter 6 is closed, the parts feeder is driven for a predetermined time by a signal from the parts feeder drive control device. As a result, the yarn thread that has risen in the spiral passage 2 is in front of the shutter 6 that is closed, and in this state, the driving of the parts feeder is stopped after a predetermined time has elapsed. Thereby,
When a yarn thread request signal is input from the yarn thread conveyer 11 and the shutter 6 is opened and the parts feeder is driven, the yarn thread that has been waiting immediately before the shutter 6 immediately passes through the carry-out port and is conveyed to the yarn thread. Transferred to the conveyor 11. As a result, the yarn can be smoothly supplied without waiting time in each yarn supplying process in the yarn supplying device.

[0028]

Since the present invention is configured and operates as described above, the shutter of the parts feeder is closed, and the parts feeder is driven and closed for a predetermined time while waiting for the work to carry out the yarn to the next step. The yarn is sent immediately before the shutter and enters the standby state, so the yarn request signal from the next process is input, and the yarn can be carried out of the parts feeder immediately after the shutter is opened, and the yarn can be smoothly transferred to the next process. It can be carried out and the processing capacity of the parts feeder can be improved.
