[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a doffing system of a take-up winder for receiving a full pipe from a bobbin holder of a plurality of take-up winders and inserting an empty paper tube.

[0002]

2. Description of the Related Art In recent years, the receiving of a full tube and the insertion of a paper tube into a bobbin holder of a plurality of spinning winders are automated by using a doffing device equipped with a full tube receiving means and a paper tube inserting means. Is being done. A conventional automation example using such a doffing device will be described with reference to FIGS.

In FIG. 4, 1 is a take-up winder, 2 is a doffing device, 3 is a peg stand, 4 is a paper tube feeding device, and 5 is a self-propelled carrier. At the same time when the doffing device 2 stops in front of the specific take-up winder 1 that requires doffing and receives a full pipe (fruit),
The paper tube (empty) received from the paper tube supply device 4 is inserted into the take-up winder 1. Then, the doffing device 2 travels to the front of the peg stand 4 and transfers the full pipe (actual) to the peg shaft of the peg stand 4. Then, the peg stand 4 on which the full pipe is transferred slides sideways, moves onto the self-propelled carrier 5, and is transported to an automatic warehouse or the like.

Next, the conventional structure and operation of such a doffing device 2 will be described with reference to FIG. A doffing device 2 is movably arranged along the row of the take-up winders 1 with an operation passage therebetween, and a peg stand 3 is arranged at the right end of the row of the take-up winders 1. Further, a platform 6 is installed right above the traveling path of the doffing device 2, and a paper tube feeding device 4 is installed upright on the platform 6 at a position corresponding to each spinning winder 1. The doffing device 2 includes a carriage 13 that travels on a rail 12 installed in parallel with a row of the take-up winders 1, and a slide stand that can slide on the carriage 13 toward a bobbin holder BH of the take-up winder 1. 15, a column 16 on the slide base 15, and a paper tube support shaft 11 and a full tube support shaft 14 that are vertically movable or fixedly provided on the column 16.

The operation of the doffing device 2 described above will be described below. First, the doffing device 2 travels and stops up to the front of the fully-wound spinning winder 1. Then, in order to receive the full pipe P by the full pipe support shaft 14, the slide base 15 is moved forward in the direction, the tip of the bobbin holder BH and the front end of the full pipe support shaft 14 are abutted and fitted, and the pusher on the side of the take-up winder 1 is pushed. Then, the full pipe P is received by the full pipe support shaft 14. In the meantime, the paper tube support shaft 11 pivots from the horizontal position to the vertical position and rises (moves),
The paper tube B is inserted into the paper tube support shaft 11 from the paper tube supply device 4. Then, the paper tube support shaft 11 pivots to a horizontal position and descends to the same height as the full tube support shaft 14 (operation),
The position is parallel to the full pipe support shaft 14. Next, after releasing the contact fitting between the tip of the bobbin holder BH and the tip of the full pipe support shaft 14, the carriage 13 travels the distance L in the direction. This distance L corresponds to the distance L between the full tube support shaft 14 and the paper tube support shaft 11. Then, the tip of the bobbin holder BH and the paper tube support shaft 11
The tips are brought into contact with each other, and the paper tube B is pushed out and inserted by a pusher (not shown) on the paper tube support shaft 11 side. And
The slide base 15 retracts in the direction. Next, the doffing device 2 travels to the front of the peg stand 3 at the right end of the take-up winder 1, and the full pipe P of the full pipe support shaft 14 is inserted into the peg shaft 3 a of the peg stand 3. Then, the doffing device 2 runs again toward the other full-scale take-up winder 1.

[0006]

By the way, in the above-mentioned doffing system, the full pipe P from the specific spinning winder 1
When it receives, the travel to the peg stand 3 provided at the end of the take-up winder train is performed and the full pipe 3 is not transferred, until the next take-up of the take-up winder 1 can be performed. In the case of random doffing, it usually takes time to doff the next spinning winder, and the doffing system as shown in FIG. 5 does not cause any problems. However, in the case of sequential doffing, doffing is continuously performed. Therefore, if the doffing device 2 travels to the end of the take-up winder row at each doffing, the doffing may not be in time. Had. Therefore, a peg stand is movably arranged along the traveling path of the doffing device 2 on the opposite side of the take-up winder row, and a full pipe is transferred to the peg stand each time the doffing device 2 doffs. However, it is possible to use systim that shortens the doffing cycle. However, if the peg stand is arranged to run freely in addition to the doffing device 2 along the take-up winder train, the traveling space provided along the take-up winder train becomes too wide. .

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to perform doffing corresponding to continuous doffing as in the case of sequential doffing. It is an object of the present invention to provide a doffing system for a take-up winder, which can shorten the cycle and does not expand the space provided for the doffing along the take-up winder.

[0008]

In order to solve the above problems, in a doffing system of a take-up winder according to the present invention, a doffing device that receives a full pipe is arranged so that it can travel along a row of the take-up winders. A creel carrier that receives the transfer of the full pipe from the doffing device is movably arranged on the ceiling side along the travel route of the doffing device, and the transfer of the full pipe to the creel carrier is performed. Means are provided in the doffing device.

[0009]

[Operation] When the doffing device receives a full pipe, the full pipe transfer means of the doffing device transfers the full pipe to the creel conveyor vehicle on the ceiling side, and the creel conveyor vehicle reaches the end of the take-up winder train. Transport the tube. Then, the doffing device performs doffing for the next spinning winder while the creel transporting vehicle transports a full pipe. The running space of the creel carrier and the doffing device is divided into upper and lower parts, and the ground side space for doffing along the take-up winder does not change.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a device layout view of a doffing system for a take-up winder according to the present invention.

In FIG. 1, 21 is a take-up winder, 22 is a doffing device, 23 is a creel carrier, 24 is a transfer device, and 2 is a transfer device.

The creel carrier is movably arranged on a rail 27 on the ceiling provided along the line of the take-up winder. The doffing device 22 has the basic function of receiving the full pipe P from the bobbin holder BH and inserting the empty paper pipe B, the function of transferring the received full pipe P to the creel carrier 23, and the empty paper pipe B. It has the function of storing and supplying.

These functions of the doffing device 22 will be described with reference to FIGS. First, the full pipe receiving means and the full pipe transfer means will be described. In FIG. 3, a first slide body 32 on which a full pipe support shaft 31 is provided is provided slidably with respect to the second slide body 33 in the thickness direction of the paper surface. The second slide body 33 is slidable in the thickness direction of the drawing with respect to the swivel base 34, and the full pipe support shaft 31 can be slid with a double stroke by the double speed drive device 35 that is a combination of a rack and a pinion. Two sets of the second slide bodies 33 and the like are provided on the right and left sides of the swivel base 34 so that the full pipe P of the take-up winder can be divided into two and received.

The swivel base 34 is rotatably supported by an elevating frame 37 by a vertical shaft 36. The elevating frame 37 can move up and down along the side frame 38. When the full pipe support shaft 31 faces the bobbin holder BH and faces forward as shown in FIG. 1, the full pipe P pushed out from the spin winder 1 is received. As shown in FIG. 2, when the full pipe support shaft 31 faces rearward at an upper position facing the peg shaft 23 a of the creel transport vehicle 23, the full pipe P is transferred to the creel transport vehicle 23. In addition, 39 is a pusher for transferring the full pipe P.

Next, the function of storing, supplying and inserting the empty paper tube B will be described with reference to FIG. A paper tube box 41 for stacking empty paper tubes B vertically in two rows beside the side frame 38.
Is provided. A cutting device 42 is provided in each row of the paper tube box 41, and P1, P2, P5, and
The paper tubes can be sequentially dropped at any of the P6 positions. A slide rail 43 is provided below the P1 to P6 positions, and a first slide base 44 is provided.
Is slidably mounted so that it can be positioned at the desired P1 to P6 positions.

A second slide body 45 slidable in the thickness direction of the paper is mounted on the first slide base 44, and a third slide body 46 slidable in the thickness direction of the paper is mounted on the second slide body 45. An empty paper tube support frame 47 having a pusher 48 therein is attached to the third slide body 46. Then, the empty paper tube support frame 47 can be slid in the thickness direction of the paper with a double stroke by the double speed drive device 49 by the combination of the rack and the pinion. As shown in FIG. 2, when the paper tube support frame 47 slides to a position facing the bobbin holder BH, the pusher 48 can insert an empty paper tube into the bobbin holder BH.

Further, the creel carrier 23 will be described with reference to FIG. The creel carrier 23 has four peg shafts 23a, which correspond to a full tube for one bobbin holder BH, projecting laterally, and a predetermined full tube support shaft 31 of the stopped doffing device 22 has a predetermined full tube support shaft 31. It is free to travel so that the peg shafts 23a face each other. Then, as shown in FIG. 2, the full pipes P are transferred one by one from the full pipe support shaft 31 facing the rear surface to the peg shaft 23a.

The creel carrier 23, which is fully loaded with the full pipe P, travels to the home position facing the transfer device 24. The transfer device 24 is slidable between a horizontal frame 52, which supports the chuck 51 so as to swing sideways or downward, between an advancing position facing the creel transport vehicle 23 or a retracted position directly above the tray 27 of the conveyor 25. It is supported by the elevating frame 53. The sideways chucks 51 receive the full pipes P from the four creel transport vehicles 23 all at once, and then the four full pipes P.
Can be transferred to the tray 27 at the same time. Then, the tray 27 is conveyed to the stocker (not shown) by the conveyor 25.

The doffing operation by the above-mentioned doffing system will be described with reference to FIGS. In FIG. 1, the spin winder 1 is sequentially doffed from left to right. First, the doffing device 22 sets the full pipe support shaft 31 on the right side to the bobbin holder BH.
And receive two full pipes P. The doffing device 22 travels a distance L so that the left full pipe support shaft 31 faces the bobbin holder BH, and further receives two full pipes P. Then, as the elevating frame 37 rises, the swivel base 33
Turns 180 degrees and becomes the state of FIG. Then, one full pipe P is transferred onto the peg shaft 23 a of the creel carrier vehicle 23.
The creel transporting vehicle 23 travels in the thickness direction of the paper, the next peg shaft 23a faces the full pipe support shaft 31, and sequentially receives the full pipe P. In this way, the creel transport vehicle 23, after receiving the transfer of the four full pipes P, travels to a position facing the transfer device 24 of FIG.
Reprint up to 7.

At the same time as the full tube support shaft 31 moves up as shown in FIG. 2, the empty paper tube support frame 47 supporting the two empty paper tubes B slides to a position facing the bobbin holder BH,
The pusher 48 inserts two empty paper tubes B. Further, the empty paper tube support frame 47 is provided with two paper tubes B from the paper tube box 41.
Is supplied to the bobbin holder BH, and again slides. This paper tube inserting operation is performed while the full tube P is transferred onto the creel transport vehicle 23. Therefore,
The cycle time of the doffing device 22 is determined by the time until the full pipe P is received and transferred to the creel transport vehicle 23, and can be considerably shortened as compared with the case where the full pipe P is transported. Further, since the doffing device 22 itself stores the empty paper tube B and performs the supply and the insertion in a series of operations, it is not necessary to separately provide the paper tube feeding device along the take-up winder 1, and the empty paper tube insertion The cycle time can also be shortened.

Incidentally, the reason why the four full tubes or empty paper tubes of the bobbin holder BH are received or inserted in two portions in two steps is to narrow the machine width of the doffing device 22. If the doffing device 22 has enough space to widen the machine width, a doffing device that can receive or insert four full pipes or empty paper pipes at one time can be used. Even in this case, 4
It is only necessary to provide a space in which the doffing device having a machine width corresponding to each piece runs along the line of the take-up winder, and a creel is provided for the running of the doffing device on the ceiling side different from the space on the ground side. Since the carrier vehicle is provided, the space on the ground side for doffing along the take-up winder does not need to be expanded by the creel carrier vehicle.

[0021]

As described above, in the doffing system for the take-up winder of the present invention, the creel carrier for transporting the full pipe is separately arranged from the doffing device so as to be movable along the ceiling side. So
Compared to the conventional case where a doffing device carries out full pipe feeding, it is not necessary to wait for the next doffing for full pipe feeding, the cycle time is shortened, and the sequential doffing of the spinning winder is reduced. It is possible to deal with doffing in a short time. Further, since the creel carrier is movably provided on the ceiling side, the doffing device provided along the spinning winder is determined by the doffing device, and it is not necessary to expand the space on the ground side.
