[Conventional technology]

As shown in FIG. 4 to FIG. 6, a conventional device for operating a winding foiler wire during doffing of a Mule spinning machine is a bearing (not shown) attached to a spindle carage (hereinafter, simply referred to as a carrage). ) Supporting the winding forum shaft 2 and the winding forum handle 3 loosely fitted on the shaft 2
, A winding forum sickle 4 arranged to rotate with the rotation of the handle 3, a winding forumer wire 5 attached to the tip side of the sickle 4, and a manual attachment attached to the winding forum handle 3. It is known to include a handle 17.

Here, the manual handle 17 manually rotates the winding forum handle 3 and the winding forum sickle 4 around the winding forum shaft 2 to move the winding forum wire 5 from a position substantially above the cup 11 to a spindle bottom position B. Can be moved up to.

In the spinning process in this Mule spinning machine, the sliver 6 supplied is connected to a paper tube 10 mounted on a rotating spindle 9, and the carrage 1 is extended outward to be stretched and simultaneously twisted to form a yarn. Next, this yarn is wound around the paper tube 10 while being synchronized with the inward movement of the carrage 1 via the counter-follower wire 8 while the position of the winding-forler wire 5 is raised by a cam device by a not-shown cupping rail. The cup 11 is manufactured by repeating the process. And the predetermined cup 11
In the case where the paper is made, it is taken out from the spindle 9, so-called doffing is performed, and then a new paper tube is attached to the spindle 9 to make cups one after another.

On the other hand, at the time of this doffing, the following operation is conventionally performed using the above-mentioned device, as shown in FIG. 5 and FIG.

That is, first, the yarn of the portion that has been wound around the cup 11 is gripped by the counterfora wire 8 and moved up and down to loosen the yarn. After that, the manual handle 17 is lifted up and the winding forum handle 3 and the winding forum sickle 4 are rotated, so that the winding forum wire 5 is exposed at the paper core at the bottom of the cup 11 (hereinafter referred to as the tail roll position). I said) to A. Then, in an operation console (not shown) arranged away from the carrage 1, the spindle 9 is rotated at the same time as the inward movement due to the inching of the carrage 1 (notching), so that the ball tail winding shown in FIG. I do.

Then, in the same manner as described above, the winding forum handle 3 is manually operated to lower the winding forum wire 5 to the spindle bottom position (hereinafter referred to as the spindle bare winding position) B, and as shown in FIG. Nine winding of the yarn several times around 9 itself, and bare spindle winding. After that, as shown in FIG. 7C, when the manual handle is released, the wire 5 returns to the cup winding start position and then the doffing is performed. At that time, the ball tail winding position A and the spindle bare winding position B The thread will be cut between and.

[Problems to be solved by the device]

In the above-mentioned conventional actuating device, since the winding foiler wire 5 is manually operated and this operating position is separated from the operation console, one person operates the handle during doffing and one operator operates the carrage 1 on the operation console. Needed people.

Further, in the present apparatus, usually, since a large number of spindles 9 are provided, the winding foiler wire 5 also becomes long in the lateral direction, the winding foil sill 4 holding the winding wire 5 also becomes large, and the coil springs supporting it also become large in number. Become. Therefore, since it is necessary to move a large number of winding foil sickle 4 by operating this manual handle 17, the arm force required for that is large, and therefore, a mistake in controlling the winding wire wire position is likely to occur, and therefore the winding position is It was sometimes bad.

Further, conventionally, a doffing operator releases his hand from the winding forum handle 3. Therefore, due to the spring force of the coil spring, the position of the winding foiler wire 5 is returned to the cup winding start position C shown in FIG. 6C, and the tension of the bare spindle is relaxed. It becomes easier for the minutes to come out as the cup is removed. In order to prevent this, the conventional operator has to pull out the cup with the other hand while holding the bare winding part with one hand, which causes a problem that the doffing cannot be performed smoothly.

The present invention solves the above problems, and an object of the present invention is to provide an operating device for a winding foiler wire that enables simple, reliable, and smooth doffing by machine operation and remote operation on the operation console. To do.

[Means for Solving the Problems]

The operating device is a hydraulic cylinder or a pneumatic cylinder capable of rotating the winding forum handle and the winding forum sickle about the winding forum shaft to move the winding forum wire from a position substantially above the cup to a bare spindle winding position. It is characterized by including a cylinder. The mounting position of the cylinder is not particularly limited, but usually
It is installed almost in the center of the carriage.

[Action]

With the above-described configuration, as shown in FIGS. 1 to 3, when performing tail-end winding and bare spindle winding during doffing, the cylinder 12 is operated and the cylinder rod 12a is advanced (pushed) or retracted (pulled) appropriately. ) Or when stopped, the winding forum wire 4 can also be rotated in accordance with the rotation of the winding handle 3 and the winding wire 5 can be stopped at a desired position.

First, as shown in FIG. 3 (a), the winding foiler wire 5 is set to the tail end winding position A, and the carrage 1
Is moved inward, and at the same time, in synchronization with this, the spindle 9 is rotated to wind an appropriate number (about 4 rotations) around the ball end, and the carrage 1 is stopped. Then, further activate the cylinder 12,
As shown in FIG. 7B, the winding foiler wire 5 is set to the spindle bare winding position B, the spindle carriage 1 is moved inward, and the spindle bare winding is similarly moved to an appropriate number (4
Carriage 1 is stopped. Preparation of deep-fried chicken is completed.

After that, fried chicken is done. At that time, the yarn is cut between the tail end winding position A and the bare spindle winding position B. Then, a new paper tube is inserted into the spindle 9 from which the cup 11 has been removed, and the production of the next cup begins.

[Effect of device]

As described in the above action, this operating device can operate the cylinders on the operation console for operating the carage. Therefore, not only the operation of the carages but also the operation of the winding foiler wire during doffing can be performed on this operation console. Can also be done. Therefore, this operating device can operate the winding foiler wire not by manual operation but by mechanical operation and by remote operation, so that even a single worker can very easily do the doffing without requiring large arm force. It can be carried out.

Further, according to the present operating device, by stopping the operation of the cylinder at the position where the spindle is barely wound, the doffing work can be performed while the winding foiler wire is stopped, so that the tension at the portion where the spindle is barely wound can be prevented from being loosened. . Therefore, unlike the conventional case, it is not necessary to hold the bare winding portion with one hand, and the cup can be pulled out (deep-fried) with both hands, and the doffing work time can be greatly shortened.

From the above, the present actuating device is extremely useful as compared with the conventional device.

This device is a carrage 1 that goes in and out, a winding forum shaft 2, a counter forum shaft 6, a winding handle handle 3, a winding forum sickle 4, a counter forum sickle 7, and the tip of each sickle. A winding forum wire 5, a counter forum wire 8 and a cylinder 12 mounted on the side. That is, except for the cylinder, it is substantially the same as the conventionally known device. Therefore, regarding the same parts as the conventional device shown in FIGS. 4 to 6,
The same reference numerals are given and the description thereof is omitted.

The cylinder 12 is of a hydraulic type or a pneumatic type, and is shaken within a predetermined angle range on a bracket 14 which is attached to one side of the base 1a of the carrage 1 and which is formed in a substantially L shape. It is pivotally mounted via a shaft 15 so that it can move freely.
This is a manually operated type operated by a push button (not shown) arranged on the operation console.

The winding forum handle 3 is formed in a hook shape, and one end of the winding forum handle 3 is loosely fitted to a winding forum shaft 2 supported by a bearing attached to the carrage 1. And the other end is a cylinder
Twelve cylinder rods 12a are axially supported by pinning at the tip end portions of the shaft body 15 so that the axial direction of the shaft body 15 is substantially the same as the axial direction, thus forming a slider crank mechanism. In addition, 13 in the figure
Is a winding forum cam fixed to the shaft 2.

Further, the winding forum sickle 4, which is curved like a hook, is attached to the winding forum shaft 2 so that the winding forum shaft 2 can be similarly rotated in response to the rotation of the winding forum handle 3. It has become. The winding foiler wire 5 penetrates the tip end of the winding foiler wire sickle 4 and is stretched in the lateral direction of the carrage 1. The winding foiler wire 5 takes up the yarn wound on a plurality of spindles (not shown).

The counterfora sickle 7 is formed in an arc shape, and one end of the counterfora sickle 7 has a winding fora shaft 2
Similarly to the above, the counter wheel shaft 6 supported by the bearing is fitted. Then, a counter-follower wire 8 is pierced through the tip portion thereof, and the wire 8 is stretched in parallel with the winding-forler wire 5 and wound around the paper tube 9 after the sliver 16 is twisted. It is also a guide for the case.

The spindle 9 is mounted above the base 1a of the carrage 1 in a state of being inclined by about 15 degrees in the direction of the head stock (not shown). This is rotated by a rotation drive device (not shown), and the paper tube 9 is inserted therein.

A cup is produced in a Mule spinning machine, and when doffing, a cylinder 12 as an operating device of the winding foiler wire 5 is actuated as shown in FIG. 2, and a cylinder rod 12a is moved forward to move the winding foiler handle. 3 is rotated. In conjunction with this, the winding forum sickle 4 is rotated, and the winding forum wire 5 at the tip end thereof is moved from a portion slightly above the upper end of the cup 11 between the spindle bare winding positions B in this example. Is configured to.

Next, as shown in FIG. 3 (a), at the time of doffing, first, the yarn of the portion that has been wound around the cup 11 is grasped by the counterforler wire 8 by hand and moved up and down to be loosened. Then, the cylinder 12 is operated to control the winding forumer wire 5 to lower it to the tail edge winding position A.

After that, in the operation console installed away from the carrage 1, the spindle 9 is rotated at the same time as the carrage 1 is moved inward, and the tail is wound. Further, as shown in FIG. 7B, the winding foiler wire 5 is operated in the same manner as described above to lower it to the spindle bare winding position B to perform bare spindle winding.

After that, if the cup 11 is pulled out from the spindle 9 according to the same procedure as the conventional one, the yarn will be cut between the tail edge winding position A and the bare spindle winding position B, and
Since the thread is connected to the spindle without being separated, the next cup can be continuously manufactured.

As described above, according to the present device, since the operation of the winding foiler wire 5 at the time of doffing can be performed by the cylinder 12, it is possible to perform the machine operation and the remote operation on the operation console, and further by one operator, and You can surely doage. Further, by stopping the operation of the cylinder 12 at the position where the spindle is barely wound, the winding foiler wire 5 can be stopped and the doffing work can be performed, so that the doffing can be performed with both hands, and the working time can be greatly shortened. When a hydraulic cylinder is used as the cylinder, the accuracy of the stopping position of the winding foiler wire can be further increased, and both can be used together depending on the number of spindles and the like.

It should be noted that the present invention is not limited to the specific embodiment described above, and various modifications may be made within the scope of the present invention depending on the purpose and application. That is, the operation of the cylinder may be automatic rather than manual as described above. In this automatic system, the above steps, the position of each wire, the operation of the carrage, etc. are performed by electronic control. When the length of the yarn is short due to the slackening operation, the yarn may be broken due to the positive lowering of the wire. Therefore, in order to prevent this, the supply pressure of the cylinder for operating the winding foiler wire can be appropriately adjusted for each fine spinning yarn count to prevent the yarn breakage.
