DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roving process in which roving machines equipped with staggered upper-supported flyers are arranged in two rows, and a carrier for hanging roving windings in two rows on both left and right sides. The present invention relates to a roving bobbin conveying method and a roving bobbin conveying system to and from a spinning step in which a plurality of spinning machines provided with creels arranged and arranged.

[0002]

2. Description of the Related Art In recent years, in order to save labor in spinning factories,
The roving bobbin is transported during the roving / spinning process, instead of being transported by placing the bobbin on a bogie, the roving bobbin is transported (running) along a rail erected on the ceiling by the roving machine. 2. Description of the Related Art A roving transport system for suspending and transporting an empty bobbin after roving has been used in a bobbin or a spinning machine has been implemented.

In the roving and spinning machines, in order to reduce the size of the frame, the arrangement of the flyer and the spindle and the arrangement of the roving bobbins for supplying the roving to the draft part are set at appropriate intervals. In the roving machine, the flyers are arranged in two rows in a staggered manner, and the bobbin wheels are also arranged in two rows in a staggered manner correspondingly. In addition, in a spinning machine, preliminary roving is generally performed. In a spinning machine that performs a preliminary roving change, a preliminary roving winding (preliminary roving bobbin) is suspended in a single row on preliminary roving winding rails provided on both the left and right sides of the machine stand, and suspended by a creel to supply roving. When the inner roving bobbin approaches empty, the roving bobbin is replaced with a spare roving.
In a roving yarn transport system that transports a roving bobbin between a spinning machine that performs preliminary roving change and a roving machine, a transport body in which a preliminary roving bobbin is suspended in a single row is loaded into a preliminary roving winding rail.

[0004] The arrangement pitch of the bobbin wheels of the roving machine,
The pitch of the roving bobbins suspended from the preliminary roving winding rail of the spinning machine is different from each other. Therefore, the full bobbin pitch is changed to the predetermined pitch on the spare roving winding rail before the full bobbin on the bobbin wheel produced by the roving machine is suspended on the carrier and carried into the spare roving winding rail of the spinning machine. There is a need to. In addition, the pitch of the remaining roving bobbin after being used by the spinning machine suspended on the carrier on the preliminary roving winding rail, the roving rail extending above the front side of the roving machine after the remaining roving process. It is necessary to change to the arrangement pitch of the bobbin wheels of the roving machine before being carried into the roving machine.

There is a method in which the pitch of the roving bobbin is changed by a pipe changing device which intermittently moves along a roving machine and performs a pipe changing operation for a plurality of bobbins (for example, JP-A-61-17).
No. 4432). Further, Japanese Patent Application Laid-Open Nos. 61-197376 and 61-102429 disclose a method of using a transport body constituted by connecting links that can be bent at the pitch of a roving bobbin in a preliminary roving winding rail. Is disclosed. In this method, the transport body is loaded in a zigzag shape on the roving rail, and the full bobbins produced by the roving machine are hung in a staggered manner on the transport body and doffed. The pitch is changed by loading the roving winding rail in a straight line.

However, the method disclosed in Japanese Patent Application Laid-Open No. 61-174432 complicates the structure of the switching device. In addition, since the staggered arrangement is changed to a straight line and suspended on the carrier on the roving rail, the roving rail is longer than the roving machine and the carrier is moved in accordance with the pipe change operation. There is also a problem that a moving device for causing the movement is required.

On the other hand, Japanese Patent Application Laid-Open No. 61-197376 discloses
In the case of the method disclosed in Japanese Patent Application Laid-Open No. 61-102429 or the like, the configuration of the tube changing device is simpler than that disclosed in Japanese Patent Application Laid-Open No. 61-174432, The number of bearings increases, the structure of the carrier is complicated, and the manufacturing cost increases.

Further, in the above-mentioned conventional method, since the carrier is shared by the roving frame and the spinning frame, the number of bobbin hangers per carrier must be set to a number that can be shared by the roving frame and the spinning frame. In addition, it was difficult to form a bobbin transport system in which roving and spinning machines having different numbers of spindles coexist.

A method for solving these problems is disclosed in Japanese Unexamined Patent Publication No.
No. 157,144. in this way,
As shown in FIG. 14, a first transporting body 61 for transporting the bobbin in the roving process and a second transporting body 61 for transporting the bobbin in the spinning process.

9 and lifting means (not shown) for raising and lowering the four slide devices 69 at the same time. Then, by driving and controlling the lifting / lowering means and the four slide devices 69,
The full bobbin F and the empty bobbin E are exchanged between the first transport body 61 and the second transport body 62 while changing the pitch.

[0011]

However, in the conventional apparatus, when the bobbin is exchanged between the first carrier 61 and the second carrier 62, it is necessary to change the pitch. The mechanism for the change becomes complicated. Further, at the time of replacement work by the bobbin replacement device 66, an operation of moving the first and second transport bodies 61 and 62 by a predetermined amount is also required.
There is a problem that the control becomes complicated.

You. The second carrier 13 is carried into the creel rail 12 of the spinning machine 2 requiring the full bobbin F by the operation of the transfer device 24.

This embodiment has the following effects. (B) A plurality of bobbins can be replaced one by one without changing the pitch of the roving bobbins (full bobbin F and empty bobbin E) suspended on the transport bodies 5 and 13 moving on different traveling rails 3 and 14. It can be carried out. Therefore, as compared with the case where the pitch needs to be changed at the time of bobbin replacement, the configuration of the device and the control are simplified. Maintenance is also simplified.

(B) Since the first traveling rail 3 and the second traveling rail 14 are arranged so as to extend in parallel with each other at the position where the bobbin exchanging device 25 is provided, the vicinity of the bobbin exchanging device 25 is provided. Both running rails at 3,
14 becomes simple.

(C) The bobbins F and B are exchanged with the full bobbin F removed from the first carrier 5 and the empty bobbin E removed from the second carrier 13 in a state where their arrangement directions are changed by 90 °.

(D) The first and second pegs 40a, 40b, 41a, 41b while the rotation base 35 makes a half turn.
Since the planetary gear mechanism is used as the mechanism for changing the arrangement direction by 90 degrees, the predetermined angle can be reliably changed with a simple configuration.

(E) Since the cylinder 26 and the linear guide 28 are combined as the lifting / lowering means, the support plate 32 supporting the rotating means can be raised / lowered while preventing its rotation. There is no danger that the relative position of the rotating means changes during elevating.

(F) The roving frame rails 4a and 4b are configured to be connectable to the first traveling rail 3 at both ends, so that the first carrier 5 can be loaded and unloaded only from one side. Compared with the configuration, the waiting time for carrying in and carrying out work to the roving rails 4a and 4b is reduced.

(G) Since separate transporters are used for the roving frame 1 and the spinning frame 2, the number of bobbin hangers per transporter can be set independently of each other. It is easy to set up a bobbin transport system in which the spinning machines coexist.

(H) Since the creel rail 12 can be connected to the second traveling rail 14 at both ends thereof, it can be compared with a configuration in which the second transport body 13 is loaded and unloaded from only one side. Thus, the waiting time for carrying in and out the creel rail 12 is reduced. As a result, the operating rate of the spinning machine is improved.

The embodiment is not limited to the above, but may be embodied as follows, for example. In the case where the bobbin exchange is performed at the same height of the traveling positions of the two transport bodies 5 and 13, the bobbin exchanging device 25 is provided on a curved portion of the first traveling rail 3 or the second traveling rail 14. For example, as shown in FIG.
The bobbin exchange device 25 is provided at a position where the curved portion of the second traveling rail 14 and the straight portion of the second traveling rail 14 are close to each other. In this case, since the heights of the two carriers 5 and 13 are the same, as shown in FIG.

For example, the moving body 57 with the full bobbin removed from the first carrier 5 is moved from the position shown by the solid line in FIG. 13 along the guide groove 56 so as to turn counterclockwise in FIG. Is moved to a position corresponding to the bobbin hanger 9 of the second transport body 13 via the intermediate position indicated by. The moving body 57 to which the empty bobbin removed from the second transport body 13 is attached is moved along the guide groove 56 from the position shown by the solid line in FIG. Is moved to a position corresponding to the bobbin hanger 9 of the first transport body 5 via the intermediate position indicated by.

As a transporter for pulling the first transport body 5, for example, a transporter disclosed in Japanese Patent Application Laid-Open No. Hei 1-213416 is used. Also, the second carrier 1
A battery car of a type that moves by pushing a carrier is used as the transporter for 3.

The transport members 5 and 13 are moved on the first travel rail 3 and the second travel rail 14 by using a transporter, and the roving rails 4 a and 4 b and the creel rail 12 are moved.
The upper part may be moved by the transfer devices 23 and 24.

The roving rails 4a, 4b and the creel rail 12 may be connected to the first running rail 3 and the second running rail 14 on only one side. The roving guide 19 may be provided on the machine side of the spinning machine 2 without providing the roving guide 19 on the second transport body 13.

The "roving bobbin" referred to in the present specification is a full bobbin F doffed by the roving machine 1, a roving yarn used by the spinning machine 2, and a part of the roving remains. In addition to the remaining roving bobbins, the empty bobbins on which the remaining roving has been processed, bobbins other than the full bobbins doffed by the roving machine 1 are also included.
