Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a roving bobbin on a bobbin carriage during conveyance of the roving bobbin.

[0002]

2. Description of the Related Art In a transport system for transporting a spinning machine group and a roving machine group by suspending a roving bobbin on a bobbin carriage, the number of roving bobbins required at one time by the spinning machine and the roving machine are If the number of roving bobbins that can be supplied by one-time doffing is different, for example, a spinning rail is provided on the spinning reel, and a bobbin carriage in which a roving bobbin with a quarter of the spinning machine spindle weight is hung on this auxiliary rail. When the number of roving bobbins hung on this bobbin carriage does not match the number of roving bobbins supplied by one-time doffing of the roving machine, that is, the number of roving machine spindles, , The bobbin carriage is composed of several carriage elements that can be connected and disconnected, and when the roving machine is doffing, the carriage elements are connected and disconnected in advance so as to match the number of roving machine spindles. The bobbin carriage is knitted for the roving machine, and the bobbin carriage that hangs the roving for one roving machine duffed to this bobbin carriage is connected and disconnected while being conveyed to the spinning machine. , Knitting a bobbin carriage for a fine spinning machine in which the number of roving bobbins required by the fine spinning machine are hung and supplied to the fine spinning machine (JP-A-3-67868), or as shown in FIG. When 2a and 2b are fully filled, the full bobbins are manually stacked on the bobbin trolley 8 for the full bobbin, transported to the bobbin station 9, and made to stand by.
The full bobbin is taken out from the bobbin carriage, and the full bobbin of the number of roving bobbins required by one spinning machine is mounted on the bobbin carriage and then conveyed to the spinning machine 1a through the stock rail 6A of the roving machine (special feature). No. 5-42181).

[0003]

Among the above-mentioned conventional techniques, in the former, the bobbin carriage for suspending the roving bobbins corresponding to the number of spindles of the spinning machine or the roving machine is knitted during the transfer so that the bobbin carriage is connected and disconnected. There is a problem in that the transport system itself is complicated because it requires a structure that can be formed and a knitting line that separates or connects the bobbin carriage elements. Also, the latter requires a bobbin truck to load a full bobbin, work to load a full bobbin on the bobbin truck, transport the bobbin truck to the bobbin station, and take out the full bobbin once loaded on the bobbin truck. There was also a problem that the work of hanging each one was troublesome.

[0004]

In order to solve the above problems, the present invention relates to a spinning machine in which the number of roving bobbins required by one spinning machine at one time does not match the number of spindles of one roving machine. In a roving bobbin transporting device configured to connect a plurality of roving spinning machines in parallel to each other with a spinning rail and a roving spinning group, and to hang the roving bobbin on a bobbin carriage and transport the roving bobbin along the transportation rail. , The bobbin carriage is a bobbin carriage for suspending the number of roving bobbins required by one spinning machine at one time, and the bobbin lifter provided with pegs for mounting the same number of roving bobbins as the number of bobbins on the bobbin carriage. Provided in correspondence with the roving machine, the empty bobbin carriage stands by on the transport rail above the bobbin lifter, and when the roving machine becomes full,
Move the full bobbin directly from the bobbin rail of the roving machine onto the mounting pegs of the bobbin lifter, and when the full bobbin is mounted on all the mounting pegs, raise the bobbin lifter to place the mounting pegs on the empty bobbin carriage. It is characterized in that all the full bobbins above are suspended, and when the full bobbin is left on the bobbin rail, this full bobbin is directly transferred to the mounting peg of the empty bobbin lifter.

[0005]

When the roving machine is fully stopped, the operator transfers the full bobbin on the bobbin rail to the peg on the bobbin lifter. In this case, when the full bobbins do not reach all the pegs and run short, they are replenished by the full pipe at the next doffing. Raise the bobbin lifter when full bobbins are placed on all pegs on the lifter. With this bobbin lifter, a full bobbin is mounted on an empty bobbin carriage configured to suspend the number of roving bobbins required by one spinning machine prepared on the upper transport rail at one time. When the bobbin lifter becomes empty and descends, the full bobbin remaining on the bobbin rail is transferred by the operator to the empty peg of the bobbin lifter. Then, waiting for the next doffing, the shortage of the bobbin lifter is replenished, the bobbin lifter is mounted on the bobbin carriage again, and the surplus bobbin of the roving machine is placed on the lifter that has descended.

Are connected by a transport rail 5 composed of these rails 3, 4, and 6. The main rail 6 is branched in the middle of the main rail 6 to form a stock rail 7 of an empty carriage. The empty carriage stock rail 7 has an empty bobbin returned from the spinning machine, which will be described later.
Empty bobbin carriage 1 where it is removed from 0
0 is conveyed to the bobbin transfer rail 4 on the side of the roving frame as required. The transport rail has a substantially U-shaped cross section with an opening at the bottom (see FIG. 2), and the bobbin carriage 10 travels in the transport rail 5 by rolling guide wheels 11.

As shown in FIG. 3, the bobbin carriage 10 includes a plurality of (18 in this embodiment) carriage bars 12.
Are connected by a connecting link 13. Six bobbin hangers 14 are hung at a predetermined pitch on the lower surface of each carriage bar 12, and in this embodiment, one bobbin carriage 10 hangs 108 roving bobbins corresponding to 1/4 of the number of spinning machine spindles. It has become so. The number of roving bobbins on the bobbin carriage 10 corresponds to the number of roving bobbins on one row of the creel rails of the spinning machine 1a as shown in the schematic diagram P of the bobbin carriage 10 in FIG. In response to the bobbin request, this one bobbin carriage 10 is carried into the spare rail 3, and the number of roving bobbins in one row of the creel can be replaced.

Carriage feed devices (not shown) capable of moving the bobbin carriage 10 in the longitudinal direction are arranged on the transport rail 5 at intervals shorter than the entire length of the bobbin carriage 10 at predetermined intervals. In these carriage feeders, as disclosed in Japanese Patent Laid-Open No. 60-67368, a pair of feed rollers rotated by a drive motor elastically sandwiches both sides of a carriage bar 12, and the feed rollers drive the drive motor. The bobbin carriage 10 is relayed one after another by being rotated by.

Next, the machine frame 21 for the bobbin lifter 20 installed on the front surface of the machine base of each of the rovings 2a, 2b is installed from the floor by attaching the bobbin transfer rail 4 to the top plate 22 on the upper side. is there. This machine frame 21 includes a pair of left and right columns 23.
An elevating chain 26 wound around a driving sprocket 24 and a driven sprocket 25 is provided inside and in an intermediate column 23a. The elevating chain 26 has upper and lower surfaces of an elevating member 28 having a U-shaped cross section through screw bolts 27 at both ends. It is connected.
The drive sprocket 24 includes a drive shaft 29 extending between the left and right struts 23, a drive pulley 30 and a motor pulley 3 at the ends thereof.
The lifter main body 32a of the bobbin lifter 20 is fixed to the side surface of the roving frame between the elevating members 28 by being driven by the elevating motor 32 via a drive transmission mechanism such as 1.

On the upper surface of the lifter body 20a of the bobbin lifter 20, the same number of roving bobbins as the bobbin of the bobbin carriage 10 is provided.
08 roving bobbin mounting pegs 36 are provided at the same pitch as the bobbin hangers 14 of the bobbin carriage 10, and when the bobbin carriage 10 is located at a predetermined position on the upper bobbin transfer rail 4, The bobbin hanger 14 and the peg 36 face each other vertically. In this way, the bobbin lifter 20 moves up and down along the vertical guide rails (not shown) vertically provided on the columns 23 and 23a when the bobbin lifter 20 is moved up and down.
Is attached to the bobbin hanger 14.

Next, a method of mounting the roving bobbin on the bobbin carriage constructed as described above will be described with reference to FIG. First, in order to carry the bobbin carriage 10 for the first time, for example, an empty bobbin carriage 10 is put on the bobbin transfer rail 4 of the roving machine 2a (96 spindles) and stands by. When the roving machine 2a is fully stopped, the operator directly transfers 96 full bobbins on the bobbin rail 2c to the bobbin lifter 20 (step 1).

Since the required number of bobbins is insufficient with only 96 full bobbins for one doffing operation, the bobbin carriage 10 continues to stand by in the roving machine 2a, and the full bobbin of the roving machine 2a is inspected during the second full pipe doffing. Twelve of the 96 pieces are transferred to the empty peg 36 of the bobbin lifter 20. Thus, the number of full bobbins on the bobbin lifter 20 is 108.
It becomes a book and the bobbin lifter 20 is ready to be lifted. Then, the bobbin lifter 20 is lifted and 108 full bobbins are simultaneously mounted on the empty bobbin carriage 10 of the bobbin transfer rail 4. When the bobbin lifter 20 mounts the full bobbin W on the bobbin carriage 10, the bobbin lifter 20 empties and descends, and returns to the original position, the 84 full bobbins remaining on the bobbin rail 2c move to the empty peg 36 of the bobbin lifter 20. Listed. In this manner, 108 full bobbins corresponding to 1/4 of the number of spindles of one spinning machine are suspended from the bobbin carriage 10 by the bobbin lifter 20 and transported to the spinning machine side by the full spinning of the roving machine 2a twice. (Step 2).

Next, the roving frame 2a is fully stopped, and the third doffing is performed. The operator is 2 of the bobbin carriage 10.
Full bobbin 9 on the bobbin rail 2a for carrying out the second transfer
24 out of 6 bobbin lifter 20 with empty peg 36
Then, the bobbin lifter 20 is combined with 84 full bobbins to make 108 full bobbins. The bobbin lifter 20 is lifted up and 108 full bobbins are mounted on the empty bobbin carriage 10 waiting on the bobbin transfer rail 4. When the empty bobbin lifter 20 descends and returns to its original position, 72 full bobbins remaining on the bobbin rail 2c are transferred by the operator. The bobbin carriage 10 loaded with 108 full bobbins is conveyed to the spinning machine side (step 3).

Next, the bobbin carriage 10 is conveyed for the third time, but after that, the only difference is that the number of full bobbins on the bobbin rail and the number of full bobbins on the bobbin lifter are changed, and the same description is omitted. In the third transport of the bobbin carriage 10, since 72 full bobbins have already been placed on the bobbin lifter 20, 36 full bobbins are transferred and 108 full bobbins are emptied in the fourth doffing. (Step 4). The bobbin lifter 2 is used for the fourth transport of the bobbin carriage 10.
Since 60 full bobbins have already been placed on 0, 48 full bobbins are transferred by the fifth doffing to make 108 full bobbins and mounted on the empty bobbin carriage 10. In this case, the full bobbin for one fine spinning machine is mounted with 432 full bobbins mounted on the bobbin carriage 10 conveyed to the fine spinning machine side (step 5).

In the fifth transport of the bobbin carriage, since 48 full bobbins have already been placed on the bobbin lifter 20, 60 full bobbins are transferred and 108 full bobbins are emptied in the sixth doffing. (Step 6). In the sixth transfer of the bobbin carriage, since 36 full bobbins have already been placed on the bobbin lifter 20, 72 full bobbins have been transferred to the full bobbin 10
Eight pieces are mounted on the empty bobbin carriage 20 (step 7). In the seventh transfer of the bobbin carriage, since 24 full bobbins have already been placed on the bobbin lifter 20, 84 full bobbins are transferred to make 108 full bobbins and mounted on the empty bobbin carriage 10 (step 8). .

Next, in the eighth transport of the bobbin carriage, 12 full bobbins have already been placed on the bobbin carriage 20, so in this case, the same number of full bobbins 9 as the number of spindles of the roving spindles are used.
Since all six are transferred to the bobbin lifter 20, no bobbin W remains on the bobbin rail 2c. 96 full bobbins are transferred onto the bobbin lifter 20 to be 108 full bobbins, and the bobbin lifter 20 is lifted to mount the empty bobbin carriage 10 on the bobbin transfer rail 4.
The empty bobbin lifter 20 descends and returns to its original position, but since the full bobbin W does not remain on the bobbin rail 2a, it is not necessary for the transfer operation. In this way, 96 full bobbins of the number of rovings of the roving machine are transferred to the bobbin lifter 20 by doffing 9 times of the roving machine 2a, and 8 bobbins of the bobbin carriage 10 are transferred.
One bobbin for two spinning machine spindles is supplied by one transportation to the spinning machine side. After that, the full bobbin W is repeatedly mounted on the bobbin carriage 20 from step 1.

In the 120-spindle roving machine 2b, 108 of them are placed on the bobbin lifter 20 when the tube is fully loaded for the first time, and the bobbin carriage 10 is hung and sent to the spinning machine. Next, the 12 roving bobbins remaining on the bobbin rail 2c are directly taken out and placed on the empty bobbin lifter 20 that has descended. Next, when 96 tubes are fully loaded, 96 bobbins are directly taken out onto the bobbin lifter 20 and 108 roving bobbins are placed on the bobbin lifter 20, so that 108 bobbins are suspended from the bobbin carriage 10. Therefore, 12
For 0-pitch roving machine 2b, doffing 9 times 1
The 08 bobbin carriage is conveyed to the spinning machine side 10 times. In the present invention, when the bobbin lifter is full, the full bobbin remaining on the bobbin rail of the roving machine is moved directly to the bobbin lifter that has descended by mounting the full bobbin on the bobbin carriage, so that the full bobbin on the bobbin rail is moved. Since the bobbin lifter is stocked on the bobbin lifter, the carriage for stocking the roving bobbins is unnecessary, and the bobbin carriage 10 is designed to suspend the number of roving bobbins required by the spinning machine at one time. It is not necessary to knit the bobbin carriage during the transportation between the spinning machines. In the present embodiment, one bobbin lifter is associated with one roving machine,
It is also possible to dispose two roving machines facing each other and dispose one bobbin lifter between the roving machines facing each other, or to dispose two bobbin lifters corresponding to one roving machine.

[0018]

As described above, in the method for mounting the roving bobbin on the bobbin carriage of the present application, the number of roving bobbins required for one spinning machine at one time does not match the number of spindles for one roving machine. At one time, the bobbin carriage is set as a bobbin carriage for suspending the number of roving bobbins required by the spinning machine, and when the bobbin carriage is full, the number of roving bobbins for mounting the bobbin is equal to the number of bobbins of the bobbin carriage. The full bobbin from the bobbin rail is hung on the bobbin carriage via the bobbin lifter, and when the full bobbin is left on the bobbin rail, this full bobbin is directly transferred to the empty bobbin lifter, and the stock of the roving bobbin is stored. Since the bobbin lifter is used as a part, a knitting line for knitting the bobbin carriage and a connecting / disconnecting device attached to them are not required, and the transfer system is provided. The can reduce costs easier. In addition, the bobbin carriage is not required, and the labor of transportation can be saved, and the transportation efficiency of the roving bobbin can be improved.
