Description

[Detailed Description of the Invention] Technical Field The present invention relates to a device for dividing and carrying out a full tube yarn, and particularly to a device for dividing and carrying out a full tube yarn wound by a spinning machine such as a spinning frame or a twisting machine to the outside of a spinning machine table. It is related to.

BACKGROUND OF THE INVENTION In general, many spinning machines such as spinning machines and yarn twisting machines are designed to automatically exchange a tube yarn and an empty bobbin when the bobbin is full, without manual intervention, using a tube changing device. In this type of automatic pipe changing device, the full pipe yarn 1 is conveyed to the end of the machine table by pipe conveyor conveyors 2 disposed on both sides of the machine stand of the spinning machine, and then transferred as shown in FIG. The yarn is housed in a yarn box 4 via an auxiliary conveyor 3 provided close to the end of the conveyor 2. In recent years, the number of spindles has increased in spinning machine stands, and normally there are 200 spindles worth of full yarns 1 on each side, and when these 200 full yarns 1 are housed in one yarn box 4, the yarn box 4 is Since it is large, it is inconvenient to transport or handle to subsequent processes. In addition, if 200 full-pipe yarns 1 are not stored in one pipe box 4 but 100 pieces each in two pipe boxes 4, two boxes should be prepared and 100 full-pipe threads 1 should be stored in one pipe box 4. Once fully stored, the yarn box 4 must be replaced manually. In this case, a counter is used to count the number of full yarns stored in the yarn box 4, and a signal from the counter indicates that when 100 full yarns 1 are stored in the yarn box 4, the yarn box 4 In order to perform the exchange, the circuit configuration becomes complicated.

Purpose This invention has been made in order to solve the above-mentioned conventional problems, and its purpose is to use a simple structure to transfer a predetermined number of full yarns transferred by a yarn conveyor to a plurality of yarn boxes. An object of the present invention is to provide a dividing and carrying out device for a full yarn that can be divided and stored.

Structure of the Invention In order to achieve the above-mentioned object, in this invention, a pipe is installed at a predetermined position in the middle of a pipe conveyor conveyor extending along both sides of a spinning machine, and is fitted into a peg on the conveyor when a full pipe is discharged. A yarn box that is provided with at least one detection device for detecting passage of the rear end of the fully inserted yarn to be transferred, is activated based on a detection signal from the detector, and stores the fully loaded yarn to be carried out. A switching device for changing the yarn box to another yarn box was provided near an auxiliary conveyor disposed on the exit side of the conveyor.

Example 1 A first example embodying the present invention will be described below with reference to FIGS. 2 to 6. As shown in FIG. 2, an auxiliary conveyor 3 is disposed obliquely at the exit end of the tube conveyor 2. On the outer circumferential surface of the auxiliary conveyor 3, locking protrusions 5 are protruded at intervals slightly longer than the length of the full yarn 1. A chute 7 with a switching lever as a switching device is fixed to the upper end of the frame 6 of the auxiliary conveyor 3. The chute 7 with a switching lever includes a bottom plate 8 that slides and guides the full yarns 1 that are aligned in the longitudinal direction and discharged one by one from the auxiliary conveyor 3, and a switching lever that switches the course of the full yarns 1 sliding on the bottom plate 8. 9, and the full pipe yarn 1 whose course has been changed by the switching lever 9 is transferred to the pipe box 4.
It consists of a pair of left and right chutes 10 and 11 that lead to. The switching lever 9 is fixed to a rotating shaft of a rotary cylinder 12 fixed to the bottom surface of the bottom plate 8. The chute 10, 11 consists of a vertical rear wall 13 and an inclined front wall 14, and a discharge port 15 wider than the diameter of the full-tube yarn 1 is formed at the bottom of each of the chute 10, 11.

A detection device 16 is disposed at a predetermined position near the center of the yarn conveyor 2 to detect the passage of the rear end of the full yarn 1 that is inserted into a peg on the conveyor and transferred when the yarn is fully conveyed. ing. Detection device 16
As shown in FIG. 5, a reed switch 19 is fixed to a bracket 18 fixed to a conveyor rail 17, one end is fixed to the bracket 18 via a mounting piece 20, and the reed switch 19 is attached to the other end. It consists of a leaf spring 22 to which a magnet 21 as an actuator for actuation is fixed. The leaf spring 22 biases the magnet 21 to a standby position shown by a chain line in which the reed switch 19 is not activated when the full-tube yarn 1 is not present at the corresponding position, and the full-tube yarn 1 is present at the corresponding position. At times, the magnet 21 is bent so as to come into contact with the full tube yarn 1 and position the magnet 21 in the operating position shown by the solid line, in which the reed switch 19 is actuated. When half of the full yarns 1 (100 yarns in this embodiment) are discharged from the auxiliary conveyor 3 and guided to one chute 11, the leaf spring 22 causes the rearmost full yarn 1a to contact the leaf spring 22. It is arranged at the position where it finishes passing the corresponding position.

Next, the operation of the apparatus configured as described above will be explained. When the full yarn 1 is discharged, the yarn conveyor 2 is moved in the direction of the arrow in Figs.
is transferred to the right in the figure. Until the last full-tube yarn 1a passes the position corresponding to the leaf spring 22, the leaf spring 22 is always pressed inward from the bottom of the full-tube yarn 1 to the position shown by the solid line in FIG. Retained. As a result, the magnet 21 fixed to the tip of the leaf spring 22 is held at the operating position for operating the reed switch 19 fixed to the bracket 1, and the reed switch 19 is maintained in the ON state. At this time, the switching lever 9 of the chute 7 with a switching lever is placed at the position shown by the chain line in FIG. It is housed in a yarn box 4. When the 100th full yarn 1 is discharged from the auxiliary conveyor 3 and guided into the chute 11, the full yarn 1 placed on the yarn conveyor 2
As shown by the solid line in FIG. 6, the rearmost full-tube yarn 1a finishes passing through the position corresponding to the leaf spring 22 of the detection device 16. As a result, the pressure on the leaf spring 22 inward toward the machine base by the lower part of the fully-manufactured yarn 1 is released, and the leaf spring 22 returns to the position shown by the chain line in FIG. The reed switch 19 is held in the OFF position. Based on this detection signal, the rotary cylinder 12 is actuated, and the switching lever 9 is rotated from the position shown by the chain line in FIG. 4 to the position shown by the solid line in the figure. Then, the full tube yarn 1 that had been stored in the tube box 4 from one chute 11 is changed its path and guided to the other chute 10, and is placed in the tube box 4.

9 is held in a standby position in which it is not operated, and the switching lever 9 is held in the position shown by the solid line in FIG. Therefore, in this device, up to the 100th full pipe yarn 1 is stored in the pipe box 4 through one chute 11, and the full pipe threads 1 from the 101st to the last are stored in the other pipe via the other chute 10. The yarn is stored in the yarn box 4.

Embodiment 2 Next, a second embodiment embodying the present invention will be described with reference to FIGS. 7 to 10. In the above embodiment, in order to divide the full tube 1 into two parts and carry them out,
In contrast to the fact that one detection device 16 is provided in the center of the pipe yarn transport conveyor 2 for emitting a detection signal for operating the switching lever 9 of the chute 7 with a switching lever,
The apparatus of this embodiment differs from the previous embodiment in that the detection device 16 is provided at two locations in order to carry out the full yarn 1 in three parts. Therefore, in the apparatus of this embodiment, when the yarn transport conveyor 2 is driven from the state shown in FIG. The yarn 1 is housed in one yarn box 4. Then, 1/3 full length yarn 1 is placed in one storage box 4.
At the time when the full yarn 1a at the rearmost end has been stored in the first detection device 16a, as shown in FIG. As a result, the magnet 21 that operates the reed switch 19 is returned to the standby position and held in the same manner as in the previous embodiment, and the switching lever 9 is operated based on the signal, and the full yarn 1 in the chute 7 with the switching lever is The transfer passage of the pipe 1 is now connected to the other chute 10, and the full yarn 1
is stored in the other tube box 4 via the other chute 10. The yarn transport conveyor 2 continues to drive, and when the next 1/3 of the full yarn 1 is stored in the yarn box 4, the full yarn 1 at the rear end is stored in the yarn box 4, as shown in FIG.
a has passed through the second detection device 16b. As a result, the magnet 2 of the detection device 16b
1 is returned to the standby position and held in the same manner as described above, and the reed switch 19 is turned OFF. Based on the signal, the rotary cylinder 12 is actuated and the switching lever 9 is switched again, so that the fully spun yarn 1 switches to one chute 11. After that, it is stored in the storage box 4. Note that the empty tube of the yarn box 4 placed below one of the chute 11 after the rearmost part of the full yarn 1 passes through the first detecting device 16a and before passing through the second detecting device 16b. Replace it with thread box 4. As a result, the remaining 1/3 of the full yarn 1 is stored in the newly replaced yarn box 4 via one chute 11. When all the full yarns 1 are discharged and all the pegs 2a erected on the conveyor have moved downward as shown in FIG. 10, the yarn transport conveyor 2 is stopped by the action of a limit switch (not shown).

Note that the present invention is not limited to the above-mentioned embodiments. For example, instead of providing the chute 7 with a switching lever, an ordinary chute may be used as the auxiliary conveyor 3.
In addition, at least two yarn boxes 4 are placed near the discharge port of the chute, and a yarn box changing device operated by a cylinder is provided, and the detection device 1
The yarn box changing device may be operated based on the detection signal 6 to replace the yarn box 4 that accommodates the full yarn 1 discharged from the chute. In addition, a photoelectric switch is provided as the detection device 16 instead of the combination of the reed switch 19 and the magnet 21, and when the photoelectric switch does not detect the full yarn 1 for a certain period of time, the switching lever 9 is activated based on the signal. may be activated.
