Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICABILITY The present invention relates to a bobbin carriage in a roving bobbin transporting device which suspends a roving bobbin on a bobbin carriage and automatically transports the roving between a plurality of roving machines and a number of spinning machines. Storage device.

Conventional technology Normally, the ratio of the number of spindles (rough bobbin ratio) between the roving frame and the spinning frame is
1: 4, 1: 8 in the case of long spinning frame, roving bobbins are automatically transferred between a plurality of roving frames and many spinning frames. Therefore, when replacing the roving bobbins of one spinning machine at the same time, it is necessary to store the full bobbin carriage that suspends the full roving bobbins doffed at least 4 times or at least 8 times by the roving machine on the stock rail. In addition, an empty bobbin carriage having a number of empty bobbins suspended must be stored on a stock rail so as not to hinder the roving operation of the roving machine. Therefore, the conventional full bobbin carriage stock rail and empty bobbin carriage stock rail are disclosed in
As disclosed in JP-A-51-147633, a number of bobbin carriages are stored on one side of a factory in parallel with a roving rail provided on the creel of each roving machine and a roving tube changing rail. .

The problem to be solved by the invention In order to provide a large number of full bobbin carriage stock rails and empty bobbin carriage stock rails separately on one side of the factory, a large storage space is required, and both the spinning frame and the roving frame are located below the stock rails. Since it cannot be installed, there is a problem in terms of effective utilization of the factory. Also, if a full bobbin carriage and an empty bobbin carriage are concentrated in one place in a factory that handles various types of roving bobbins, computer control for automatically transporting them becomes complicated, and it is difficult to perform efficient automatic transport. In particular, when a towing vehicle (locomotive) is connected to a bobbin carriage and transported, a towing vehicle must be allocated, and the control is complicated.

Means for Solving the Problems In order to solve such a problem, the present invention provides a roving bobbin which suspends a roving bobbin on a bobbin carriage and automatically conveys the roving between a plurality of roving machines and a number of spinning machines. In the transport device,
On the back of each roving machine, creel pillars combining vertical creel pillars and horizontal creel pillars are erected on the floor along the length of the machine, and the sliver kens arranged below the horizontal creel pillars Attach a separator rod to attach a separator to guide the sliver from the creel pillar,
Another horizontal creel pillar is provided above the horizontal creel pillar, and a plurality of stock rails in the direction along the machine stand are arranged side by side on the other horizontal creel pillar, and the stock rails are filled with full roving yarns. When the bobbin carriage on which the bobbin or the empty bobbin is suspended is guided, the lower end of the bobbin is provided at a position slightly above the horizontal creel pillar to which the separator rod is attached, and the full roving of at least one spinning machine is provided. A bobbin carriage on which a bobbin or an empty bobbin is suspended can be stored at a position above the sliver can.

Action For each roving machine, a full roving bobbin for one spinning machine doffed by the roving machine during the spinning operation of the spinning machine is suspended on a plurality of bobbin carriages, and a creel pillar at the back of the machine frame is provided. , Can be stored on the stock rail above the sliver cans, and even if it can store a large amount of bobbins, no special storage space is required. When the stock rail guides a bobbin carriage that suspends a full roving bobbin or an empty bobbin to a stock rail, relative to a horizontal creel pillar to which a separator rod for mounting a separator that guides a sliver of a sliver of a creel pillar is attached. In addition, since the lower end of the bobbin is provided at a position slightly above the horizontal creel pillar, the overall height can be reduced.

Example An example in which the weight ratio of the roving frame to the spinning frame is 1: 4 will be described below. In this embodiment, an automatic refilling device 2 described in Japanese Patent Publication No. 63-61414 is installed in front of the roving machine 1.
A roving bobbin transfer device 3 described in JP-B-63-30418 is installed at one end of the automatic refilling device 2. As is well known, a bobbin hanger 5 for one roving machine is suspended from the bobbin carriage 4 at an interval twice the spindle pitch of the spinning machine. When the roving machine during spinning is nearing full, two empty bobbins 6 suspended by the bobbin carriage 4 are transferred to the pegs 9 of the peg conveyor 8 of the automatic pipe changer 2 by the roving bobbin transfer device 3. When the roving machine is full, the roving bobbin (hereinafter simply referred to as "full bobbin") and the empty bobbin are simultaneously changed by the automatic refilling device 2, and then the full bobbin 7 on the peg of the peg conveyor 8 is transferred to the roving bobbin. The device 3 is inserted into a bobbin hanger of the bobbin carriage 4. That is, every time the roving machine is full, the empty bobbin of the bobbin carriage 4 is automatically replaced with a full bobbin.

On the floor behind the roving machine 1, the same number of sliver cans 11 as the number of weights of the roving machine are arranged in four rows. A creel pillar 10 having the following configuration is erected on the floor so as to surround these sliver canes 11. Creel pillar
10 is a pair of front and rear vertical creel pillars 12, 13 and a pair of horizontal creel pillars 14, 15 with four elbows.
The support bracket 17 is attached to the pillars 12 and 14 by bolts, and the support stay 18 is reinforced by being connected with the frame 16 in a torii shape. Vertical creel pillars 12, 13
A plurality of (seven in the illustrated example) creel pillars 10 are arranged side by side at substantially equal intervals along the machine base by mounting a stand base 19 attached to the lower end of the base on the floor surface. Below the horizontal creel pillar 15, four separator rods 20 are attached to the pillar 15 by a feed roller bracket (not shown), and the plurality of standing creel pillars 10 are held in a stable state with respect to each other. . Sliverkens 11
A bifurcated separator 40 for guiding the sliver 21 is attached to the separator rod 20 above. Underneath the horizontal creel pillar 14, four stock rails 22 and a replacement rail 23 of the next roving machine are bolted to each rail so that a full bobbin for one spinning machine can be stored. Attached to the horizontal creel pillar 14 by 24. As is apparent from FIG. 1, when the four stock rails 22 guide the bobbin carriage 4 on which the bobbin is suspended, the lower end of the bobbin is located slightly above the lower horizontal creel pillar 15. It is attached to the height that you do. From this structure, Sliverkens
It can be easily understood that the height of the creel pillar 10 can be kept low even when the stock rail 22 is provided above the position 11.

One end of the four stock rails 22 is a rail 23 for tube replacement.
And the other end is a main transport rail 25 connecting the roving frame 1 and the spinning frame 33.
It is connected to. As shown in FIG.
Are mounted below the creel of the spinning machine so that the full bobbin carriage, which suspends the full bobbin, stops at a position facing the spindle of the spinning machine 33 and spins out. A return yarn removing device 30 that removes the residual yarn of the roving bobbin that has been spun by the spinning machine and a bobbin carriage 4 that suspends the residual yarn bobbin are temporarily moved in the middle of the return conveyance rail 28 that connects the spinning machine 33 and the roving frame 1. 4 bobbin stock rails for temporary storage
29 are provided. Although not shown, the stock rail 22,
Each of the spinning rail 27, the remaining yarn bobbin stock rail 29, the main transport rail 25, and the return transport rail 28 is sandwiched in the width direction of the bobbin carriage 4 by a pair of rotating disks so that the bobbin carriage 4 extends in the longitudinal direction. The bobbin carriage conveying device described in Japanese Patent Publication No.
A plurality of sets are arranged at intervals shorter than the total length of the rails, and a switching machine described in the same publication is provided at a branch point of each rail, so that the bobbin carriage 4 is automatically conveyed.

The full bobbins doffed by the roving machines during the spinning operation of the spinning machines are stored in the stock rails 22 of the respective roving machines. When the spinning of the spinning machine is stopped to replace the roving after the spinning of the spinning machine, the operator cuts the roving and issues a completion signal. The bobbin carriage 4 suspending the remaining roving bobbin of the spinning rail 27 by the signal returns to the return transport rail 28.
At the same time, the bobbin carriage 4 of the stock rail 22 is sent to the spinning rail 27 through the main transport rail 25. By repeating this, when the four spinning rails are changed to full bobbin carriages suspending full bobbins, the operator restarts the operation by passing the roving through the trumpet of the spinning machine. The bobbin carriage 4 sent to the remaining yarn bobbin stock rail 29 is removed by the remaining yarn removing device 30 and returned to the stock rail 22 of the roving machine. If the roving bobbins to be produced are the same, a full bobbin carriage may be supplied from the stock rails 22 of a plurality of roving machines to the spinning rail 27 of one spinning machine. Is performed by a doffer moving along the frame of the roving machine, the tube changing rail 23 of the roving machine may be disposed above the roving machine in a known manner.

As described above, the present invention stores the full bobbin carriage doffed by the roving frame and the empty bobbin carriage returned from the spinning frame on the sliver cans on the back of each roving frame. There is no need to provide storage space. Each roving machine can store a full bobbin for one spinning machine, so that it is easy to handle various types of roving bobbins, and the full bobbin carriage and the empty bobbin carriage are automatically conveyed at the same time, and the roving bobbin of the spinning machine is simultaneously operated. Can be quickly replaced. In addition, there are many advantages, such as the height of the creel pillars on the underside of the roving machine can be suppressed.
