[Detailed Description of the Invention] Technical Field The present invention relates to a method and device for changing the creel of a spinning machine.
Install a row of bobbin hangers, install a spare rail above the front row bobbin hanger, and arrange the spare bobbin hanger on the spare rail.The bobbin inserted in the front row bobbin hanger can be used as a small bobbin (empty The present invention relates to a spinning machine replacement method for replacing a small bobbin (including a small bobbin) and a full bobbin previously inserted in the spare bobbin hanger, and a wire replacement device for carrying out the method.

Conventional technology and its problems In general, the diameter of the full bobbin is larger than the spindle pitch of the spinning machine, and the diameter of the full bobbin is larger than the spindle pitch of the spinning machine. They are arranged in two rows in the longitudinal direction of the machine with an interval twice the spindle pitch, and roving guides are installed between the front and rear rows of bobbin hangers, and Shinomaki bobbins are inserted into the front and rear two rows of bobbin hangers. The roving from these Shino-waki bobbins is guided by a roving guide and pulled out. When the bobbins in the front and rear rows become empty, these empty bobbins are removed from the bobbin hanger, and then full bobbins prepared in advance are manually inserted into the bobbin hanger to replace the bobbins. However, the above-mentioned Shinomaki bobbin is suspended at a height higher than the height of the worker, and the weight of a full bobbin has increased significantly in recent years, exceeding 3 kg, and the Shinomaki bobbin is Several hundred pieces per spinning machine (usually around 400 pieces)
Since a large number of wires are to be handled, the above-mentioned wire replacement work is quite labor intensive, requires an extremely large amount of manpower, and has the problem of lowering work efficiency.
Therefore, prior to the present application, the applicant of the present application developed a method and apparatus for mechanically performing the above-mentioned wire replacement work, and the method and device were published as Japanese Patent Application Laid-Open No. 81631/1983. This Shino exchange method involves loading a bobbin with a medium size into one of the two rows of bobbin hangers, front and rear, and loading a full bobbin into the other row of bobbin hangers to perform spinning. When a ball bobbin (denoted as a medium bobbin) becomes a small bobbin (including empty bobbins) and a full bobbin becomes a medium bobbin, replace the small bobbin in the front row (denoted as a small bobbin) with a full bobbin prepared in advance, and replace this bobbin. Prior to or after replacing the bobbin, the positions of the front row bobbin and the rear row bobbin are swapped together with the bobbin hanger. However, when replacing a small bobbin in the front row with a full bobbin in the Shino replacement method described above, the spare bobbin hanger must be placed on the spare rail installed above the front row bobbin hanger at the same pitch as the front row bobbin hanger. At the same time, one extra bobbin hanger for replacement is placed at the end of these spare bobbin hangers, and one of the left and right replacement arms is placed so that it is shifted by half a pitch from the hanger. Pull out one small bobbin in the front row with a peg and insert it into the above replacement bobbin hanger, then use the peg on the other replacement arm to remove one full bobbin from the spare bobbin hanger and remove the above bobbin from the front row bobbin hanger. Since the wires are inserted into the wires and the wires are replaced one by one, it takes a lot of time to complete the wire replacement for an entire row, and the number of wire replacement operations increases, increasing power costs. , I still wasn't completely satisfied with it.

Reference numeral 110 designates a hydraulic positioning cylinder, the end of which is rotatably connected to the bottom plate 28d of the main body 28, and the piston rod 110b is rotatably connected to the operating arm 109a. This positioning cylinder 110 normally has its piston rod 110b located at the backward end and rotates the cylindrical cam body 105b to the standby position, and when the Shino exchanger 27 is stopped at the working position, the piston rod 110b is located at the forward end. The cylindrical cam body 105b is moved protrusively and rotated to the positioning operation position, and the positioning groove 106b is engaged with the guide pin 25.

Next, a case will be described in which the Shino exchange work is performed using the Shino exchange machine 27 having the above configuration. First, the full bobbin 1a in the front row set on the creel of the spinning machine becomes the middle bobbin 1b, and the middle bobbin 1b in the back row becomes the small bobbin 1c.
After this, the medium bobbin 1b in the front row and the small bobbin 1c in the rear row are replaced by a Shino exchange machine (not shown), and the bobbin carriage 16 with the full bobbin 1a inserted into the spare bobbin hanger 23 is placed on the spare rail 14. When the insertion position has been determined, a worker manually moves the Shino exchanger 27 placed at a predetermined position in the factory to one end of the spinning machine,
The upper guide rollers 29, 29 of the Shino exchanger 27
is placed on the upper guide rail 24, the lower guide rollers 31, 31 are brought into contact with the lower guide rail 26, and the spinning machine is attached to the spinning frame as shown in FIG. In this state, the Shino exchanger 27 is maintained in a vertical position. Next, the worker turns on the start switch.
When activated, the travel motor 30 rotates and causes the Shino exchanger 27 to travel along the front surface of the machine base 3 toward the other end. The three bobbin supports 91 of the front change bar 71 are connected to the front row bobbin hanger 1.
1, the limit switch detects the stop cam and the rotational drive of the travel motor 30 is stopped, and the Exchange machine 27
The running of the vehicle is stopped. Next, the traveling motor 30
After a certain period of time has passed after the positioning device 10 stops, the positioning device 10
The positioning cylinder 110 of No. 2 is operated to project the piston rod 110b to the forward end, which rotates the sector gear 109 and moves the positioning drum 1
05 is rotated approximately 180 degrees clockwise in FIG. 14 to position it at the positioning operation position. As a result, the cylindrical cam body 105 of the positioning drum 105
b protrudes out of the main body 28 from the cutout window 103 of the side plate 28c, and the guide groove 106a of the fitting groove 106 engages with the guide pin 25 of the upper guide rail 24, and the guide pin 25 moves toward the positioning groove 106b. 28, and then the positioning groove 10
6b engages with the guide pin 25 to accurately position the shino exchanger 27 in the running direction at a predetermined working position and to fix it at that position. When performing the above positioning, since the cylindrical cam body 105b is formed longer than the interval between the guide pins 25, the cylindrical cam body 105b moves away from the position opposite the guide pin 25 because the Shino exchanger 27 moves too far beyond the predetermined stop position. Even if it comes off, the cylindrical cam body 105b interferes with the guide pin 25, so that the positioning cylinder 1
Positioning rotation of the cylindrical cam body 105b due to the rotation of the cylindrical cam body 105b is prevented, thereby making it possible to confirm that the Shino exchanger 27 is out of a predetermined stop position, thereby preventing positioning errors. Shino exchange machine 27 as above
With the bobbin 1c fixed at the working position, the next exchange unit 44 is operated to exchange the small bobbin 1c and the full bobbin 1a, as shown in FIGS. 15 and 16. First, in the stored state shown in 1 in FIG. 16, the lifting cylinder 63 of the outside lifting device 57 is activated and the piston rod 63b is raised to the forward end, thereby causing the outside lifting body 52 to move twice as far as the stroke of the piston rod 63b.

Then, in response to the operation completion signal, the piston rod 110b of the positioning cylinder 110 retracts and moves the positioning drum 105 approximately counterclockwise in FIG.
The cylindrical cam body 10 is rotated 180 degrees.
5b is housed in the main body 28, and the fitting groove 106 is removed from the guide pin 25. After that, the traveling motor 30
is driven again to cause the Shino exchanger 27 to travel to the left in FIG. This Shino exchanger 27 is stopped at the working position for exchanging the next three small bobbins 1c and the full bobbin 1a, and repeats the above bobbin exchange operation. Thereafter, by sequentially repeating the above operations from one end of the frame 3 to the other end, the thread exchange of the spinning machine is completed. Thereafter, the Shino exchanger 27 is removed from the machine stand 3 and moved to the next Shino exchange requesting machine stand. In addition, in parallel with the above-mentioned thread exchange, the thread of the full bobbin 1a inserted in the front row bobbin hanger 11 and the thread currently being spun are connected to complete the thread replacement work of the spinning machine. Furthermore, the small bobbin 1c inserted into the spare bobbin hanger 23 is moved above the roving frame by the movement of the bobbin carriage 16 and replaced with the full bobbin 1a.

Each short rear change bar is supported by a support device so as to be movable back and forth, and while the front change bar is being raised, the two rear change bars pass under the front change bar on both the left and right sides of the support device and move back and forth. It may also be carried out using a device that operates.

Effects As described above, in the present invention, the spare bobbin hanger is supported on the spare rail at the same pitch as the front row bobbin hanger, and the front and rear exchangers, which can move up and down and move back and forth, are mounted on the Shino changer that can run along the machine base. Equipped with two sets of change bars, these change bars are provided with a plurality of bobbin supports at the same pitch as the front row bobbin hanger, and the front and rear change bars are moved up and down and back and forth, and the bobbin support of one change bar is used to load the spare bobbin. Using the bobbin support of the other change bar, pull out the plurality of full bobbins from the hanger and the plurality of small bobbins from the front row bobbin hanger, and then transfer these full bobbins to the front row bobbin hanger from which the small bobbins were removed. are inserted into the spare bobbin hangers from which the full bobbins have been removed, and the full bobbins and small bobbins are replaced every time, and this replacement is repeated sequentially from one end of the machine to the other. The small bobbin on the front row bobbin hanger and the full bobbin on the spare bobbin hanger can be efficiently mechanically exchanged, and in particular, by using an automatic exchange machine for the bobbin on the front row bobbin hanger and the bobbin on the rear row bobbin hanger, it is possible to exchange the bobbin easily. Significant labor savings in the process can be achieved. Furthermore, even if the method described above uses two sets of change bars to replace the small bobbins on the front row bobbin hanger and the full bobbins on the spare bobbin hanger, the front change bar will rise toward the spare bobbin hanger. While the bobbin is being moved, the rear change bar passes under the rising front change bar and moves back and forth toward the front row bobbin hanger, which shortens the moving distance of the full bobbin and small bobbin. The exchange operation between a full bobbin and a small bobbin can be performed efficiently, thereby shortening the overall exchange time, and the exchange operation can be carried out using a device with a simple configuration.
