The tensor IIB, the traversing device 111F, the touch roller IIG that is driven by rolling contact with the package, and the cradle arm IIH for holding the paper tube are arranged in this order, and the tray 1
The yarn is fed out from the yarn feeding package 13 on the top of the yarn supplying package 2 and wound around the full package 15.

Next, we will explain the doffing system when the tube is full.

This conventional doffing system consists of a circulation conveyor 3' installed on the top of the automatic winder 1, an inclined passage 3'' leading from the touch roller IIG to the circulation conveyor 3', and a doffing system placed on the side of the automatic winder 1. The doffing cart 4', which can be moved freely, is a warning.

The operation of this doffing system is as follows. First, the winding unit 11 that is stopped due to full winding is displayed to that effect.

The doffing truck 4' runs toward the winding unit where the full tube is displayed. The doffing truck 4' stopped in front of the winding unit opens the cradle arm lIH, and the full package 15 rolls down the inclined passage 3'' and stops on the circulating conhair 3'.The doffing truck 4' is not shown in the figure. Take out the empty paper tube from the empty paper tube box (located on cradle arm IIH) and place the empty paper tube on cradle arm 11H.
Attach to. In addition, some doffing carts stock empty paper tubes. By repeating the above operations, full pipes are accumulated on the stopped circulation conveyor 3'. The circulation conveyor 3' is operated intermittently every standard winding time to discharge the full tubes on the circulation conveyor 3'. During this time,
The operation of the doffing truck 4' is stopped.

The figure is a block diagram showing the operation of the peg circulation conveyor and doffing truck in the doffing system of the present invention. Note that the automatic winder 1 and the tray circulation conveyor 2 are the same as those described in FIG. 5.

First, based on FIG. 1, the structure and operation of the peg circulation conveyor 3, which is a component of the doffing system of the present invention, will be explained.

The peg circulation conveyor 3 is provided at the upper part of the back of the automatic winding machine, and protrudes from one end of the automatic winding machine 1 (on the opposite side in FIG. 5).
It is possible to circulate the position facing the cradle arm 11H of all the winding units 11. This peg circulation conveyor 3 has a single-shaped arm 32 with pegs 31 projecting in the horizontal direction.
It consists of an endless chain attached at regular intervals. Then, the operator inserts the empty paper tubes 14 into the pegs 31 (the pegs without the IIII tubes, which are located every other peg) facing the automatic winding Ill. At the same time, full tubes 15 are inserted into pegs 31 (located every other peg between empty paper tube supply pegs) sent from the automatic winder 1.
is pulled out and placed on the line conveyor 33. Work on this peg circulation conveyor 3 is performed by intermittent operation at predetermined time intervals within the winding time (for example, if the winding is for 3 hours, intermittent operation is performed every 2.5 hours) or by continuous operation at low speed. The discharge of the full paper tube 15 and the supply of the empty paper tube 14 are performed simultaneously. That is, this peg circulation conveyor 3 also serves as a stock of empty paper tubes (at least as many empty paper tubes as the number of take-up units are inserted into the pegs 31 located below) and a supply.
There is no need to stock empty paper tubes for each winding unit or doffing truck. Since the peg circulation conveyor 3 transports the full paper tubes 15 by inserting the pegs 31 into the paper tubes, there is no risk that the surface yarns of the full paper tubes 15 will be damaged during conveyance. In this embodiment, the pegs 31 are arranged in a pinch arrangement in a single row and are distinguished by color, but the pegs 31 are not limited to this, and the pegs 31 can be differentiated in height or pitch to be used for full tubes 15 and for empty paper tubes. I
It is also possible to make it easier to distinguish between the four types. Alternatively, it may be a pair of pegs that are vertically adjacent to each other.

Next, the structure and operation of the doffing truck 4, which is a component of the doffing system of the present invention, will be explained based on FIGS. 2 and 3.

In FIG. 2, the doffing truck 4 is suspended by a traveling mechanism having a driving wheel 42 and a driven wheel 43 running on an angle rail 41 disposed above the automatic winding machine. The main body can run freely on the side of the automatic winder. This doffing cart 4 includes a lift device 44 and a transfer device 45 for taking out full tubes and attaching empty paper tubes, an outlet device 46 for feeding yarn, a device 47 for attaching yarn, and a peg conditioner. It has a photosensor 48,49 that confirms this.

Photo sensors 48 and 49, which are peg detection sensors, are a combination of a pair of upper and lower light emitters and light receivers, and the photo sensor 48 is attached to the empty paper tube 14 on the peg 31 of the peg circulation conveyor.
The photo sensor 49 is used to confirm that the peg 31 is empty. The thread feeding device 46 has a structure in which a cylinder device 46C that holds a chuck 46A and an air sucker 46B is attached to a slide base 46D inserted into a shaft 46B, and ultimately the thread feeding device 46 is used to thread the yarn end of the yarn feeding package 13. Chuck 46
A and the air sucker 46B can move forward and backward with respect to the thread path and can be raised and lowered. Next, the threading device 47 has a guide 47A that can be moved forward and backward by a link 47B. This guide 47A guides the yarn drawn out by the feeding device 46 to the slit of the empty paper tube.

As shown in FIG. 3, the lift device 44 includes an opener 44A for opening and closing the cradle arm, and a lift arm 44A for opening and closing the cradle arm.
It has 4B. The transfer device 45 also includes a peg shaft 45A that holds the full tube 15, a slide arm 45B to which the peg shaft 45A is attached vertically movably, and a slide arm 45A that holds the full tube 15.
A swivel base 45C on which B is slidably attached, and a swivel base 4
It has a slide stand 45D to which 5C is rotatably attached, and a rail stand 45E to which slide stand 45D is slidably attached. The lift device 44 and transfer device 45 having the above structure take out the full paper tubes 15 from the cradle arm to the peg 31 on their outward journey, and attach the empty paper tubes 14 from the peg 31 to the cradle arm on their return journey. ing. That is, the opener 44A opens the cradle arm (■ operation), the lift arm 44B rises, and the full tube 15
The peg shaft 45A is inserted into the full tube 15 as the slide arm 45B slides to the right (■ action). Then, the lift arm 44B descends (operation 2), and the full tube 15 is transferred to the peg shaft 45A. Next, the slide arm 45B slides to the left (■ operation), the swivel table 45C rotates 90 degrees clockwise (■ operation), and the slide arm 45B moves forward to insert the full tube 15 into the peg 31 (■ motion). Then, the peg shaft 45A is lowered to transfer the full tube 15 to the peg 31 (■ operation), and the slide arm 45B is retreated (■ operation). Furthermore, in order to receive the empty paper tube 14, the slide stand 45D slides to the right ([phase] action), the slide arm 45B moves forward ([phase]), and the peg shaft 45A rises to receive the empty paper tube 14. Take it (@

The operation of the doffing system based on the structure and operation of each device in the doffing truck 4 for the peg circulating conveyor 3 explained in FIGS. 1 to 3 will be explained with reference to the block diagram in FIG. 4.

In FIG. 4(a), the winding unit 11 is fully wound.
This is indicated by a lamp IIK or the like.

The doffing truck 4 that has detected this lamp IIK travels at high speed toward its winding unit 11 (block ■). When the switch S1 comes to the front of the display 11, the doffing truck 4 decelerates (■ block). When the switch S2 comes to the front of the display 11, the doffing truck 4 stops, and the positioning shown in FIG. 4(b) is performed (block 2). Next, the state of the peg circulation conveyor 3 is determined based on instructions from the control device, etc. (block 2). If the peg circulation conveyor 3 is stopped, perform a peg check of 2) blocks. In other words, Fig. 4 (
In C), the photosensors 48 and 49 check the condition of the pegs 31 of the peg circulation conveyor 3, and
8 (33) detects the empty paper tube 14, and the photo sensor 49
(S4) detects that the peg 31 is empty and confirms that the worker has installed it. If YES, the full paper tube is taken out (block 2) and the empty paper tube is attached (block 2), and the tough rollers and feed rollers are driven to start winding (block 2). In parallel with the ■~■ blocks, the opening (■ block) is performed, and the threading ([phase] block) is performed when the ■ block and ■ block are completed.

Then, check whether the yarn is set by the filler (■ block), and if it is OK, release the positioning of the doffing cart (@ block), and move toward the next winding unit (■ block). In addition, N in the ■ and ■ blocks
.

If this occurs, an alarm will be generated and the doffing truck will be inspected by a worker, but the doffing cart will be released from positioning and will move towards the next winding unit (@block). .

If the peg circulation conveyor 3 is not stopped but running in block ■, perform the same veg check as in block ■ ([phase] bronc). When it is detected that the doffing truck can be operated, the running peg circulation conveyor 3 is temporarily stopped ([phase] block). ■The line runs on the peg circulation conveyor 3 until it detects that the doffing truck can be operated.
means to run. Then, depending on the [phase] line, the full tube is taken out (■ block) and the tube is taken out (■ block). Then, upon completion of full tube removal (■ block) and empty paper tube installation (■ block), it is determined whether the peg circulation conveyor 3 is temporarily stopped ([phase] block), and if it is stopped at -, it is stopped. Restart ([phase] block).

Since the peg circulation conveyor 3 also supplies empty paper tubes at the same time as discharging full tubes, the doffing truck only needs to pick up and attach the empty paper tubes. Therefore, there is no need for the doffing truck or each take-up unit 11 to carry empty paper tubes, and the operation of the operator to supply empty paper tubes to them is simplified. Furthermore, the peg circulation conhair 3 shown in the first figure holds the full tube 15 with the pegs 31 and protects the surface layer yarn of the full tube, so it is especially suitable for rewinding synthetic fibers.

In the doffing system described above, even if the peg circulation conveyor 3 is running, the full tube discharge operation (the operation shown in the first diagram) is stopped at -, doffing is performed, and the operation is resumed immediately. The present invention is also applicable to a case in which doffing is interrupted until the peg circulating conveyor 3 completes its run Y.

Therefore, the present invention is applicable not only to automatic winding machines that are driven by a single spindle but also to automatic winding machines that are driven simultaneously.

〔Effect of the invention〕

In the doffing system of the present invention, a doffing cart for taking out full paper tubes and attaching empty paper tubes is movably disposed on the side of an automatic winding machine in which a large number of winding units are arranged in parallel, and A peg circulation conveyor for discharging full tubes and supplying empty paper tubes is installed on the top of the taker, and one of the pair of adjacent pegs of the peg circulation conhair is used as an empty peg for discharging full tubes, and the other is used as an empty peg for discharging empty paper tubes. The peg circulation conveyor is used for both discharging full tubes and supplying empty paper tubes, so it is possible to discharge full tubes and supply empty paper tubes at the same time when the peg circulation conveyor is running. Work related to supplying empty paper tubes can be simplified. In addition, since full tube discharge and empty paper tube supply are performed simultaneously, this doffing system can easily be automated using robots and the like. Furthermore, when rewinding synthetic fibers, the full tube is supported by the pegs, so there is an advantage that the surface layer yarns are not damaged.
