Description

[Detailed Description of the Invention] [Industrial Application Field] This invention mainly relates to a device for delivering empty paper tubes to a spinning wind-up machine.

[Conventional technology]

There is no known device in which an empty paper tube is held on a moving carriage, the carriage is positioned at a desired bobbin holder position of a spinning winding machine, and the empty paper tube is transferred from the carriage to the bobbin holder. (For example, Special Publication No. 49-20256).

On the other hand, when installing the paper tube into the bobbin holder of the winding machine, be sure to insert it until the end surface of the paper tube touches the innermost part of the bobbin holder to ensure smooth winding into the paper tube. above is necessary.

[Problem that the invention aims to solve]

However, despite the above request, when trying to transfer paper tubes to the bobbin holders of multiple units using the conventional device described above, the position, length, etc. of the bobbin holders in each unit are slightly different. Because of this, the paper tube is rarely transferred to the bobbin holder satisfactorily while meeting the above conditions, and it often occurs that the paper tube is installed in a defective state, which may affect subsequent winding. This led to poor quality.

This invention attempts to solve the above problems.

[Means for solving problems]

The paper tube delivery device according to this invention that solves the above problems is composed of a paper tube holding shaft and a paper tube extrusion device that pushes the paper tube held by the holding shaft toward the winding machine. The extrusion device includes a nut block screwed onto a screw shaft extending along the holding shaft of the paper tube, an extrusion plate supported movably in the direction of the screw axis with respect to the nut block, and a rotation drive connected to the screw shaft. A compression spring is interposed between the nut block and the extrusion plate to constantly bias the extrusion plate toward the winding machine, and the movement stroke of the nut block moves the paper tube toward the winding machine. When transferring the paper tube from the paper tube holding shaft on the transfer device side to the bobbin holder of the winding machine, first The extrusion plate pushes the paper tube onto the bobbin holder without bending the compression spring, and after the front end of the paper tube comes into contact with the innermost part of the bobbin holder, the extrusion plate stops, but the nut block continues to move, and the compression spring between the extrusion plate and the nut block is bent, so that the extrusion plate presses the front end of the paper tube to the innermost part of the bobbin holder with stronger pressure.

Next, the paper tube transfer device 11 provided as a paper tube transfer device according to this invention will be explained. The transfer device 11 of this example is schematically shown in FIG.
As shown in detail in FIG. 8, a paper tube holding shaft 26 horizontally protrudes from the vertical portion of the truck body 14;
A paper tube extrusion plate 27 that moves in the longitudinal direction on the shaft 26 and pushes the held paper tubes 8a and 8b to the bobbin holder 9 of the winding machines 3 and 4, and a drive mechanism 28 for the extrusion plate 27. It is composed of
They are as follows.

That is, even if the bobbin holder 9 of the winding machines 3, 4 is set to have a slightly smaller diameter than the inner diameter of the paper tubes 8a, 8b, the transfer of the paper tubes 8a, 8b from the transfer device 11 to the bobbin holder 9 is successful. The paper tube holding shaft 26 is
The inner cylinder 29 is fixed to the truck body 14, and the shaft 32 is biased by a spring 31 in a radial direction with respect to the inner cylinder 29. The shaft 32 extends through the inside of the inner cylinder 29 and is swingable via a spherical bearing 33 at the end. supported outer cylinder 34
The paper tubes 8a, 8 are attached to the outer cylinder 34.
b is inserted and held.

The shaft 32 is moved forward and backward in the left-right direction in FIG. 6 by engaging a rack rod 36 in the truck body 14 connected to the base end thereof with an output pinion gear 38 of a drive device 37, which will be described later. As the shaft 32 moves forward and backward, the outer cylinder 34 is also moved forward and backward in the left-right direction in FIG.
4 is the right end opening 34 in the right row position shown in the sixth figure.
a and an annular block 34b provided at an intermediate position inside.
are fixed in position by riding on the tapered annular blocks 29a and 29b provided on the outer periphery of the inner cylinder 29, respectively, and when they are moved to the left from the sixth figure, the opening 34a of the outer cylinder 34 and the annular block 29 are closed.
a and the annular block 34b and the annular block 29
b is disengaged, the outer cylinder 34 becomes movable relative to the inner cylinder 29, and is held elastically only by the uniform puckering force in the radial direction by the spring 31. It's summery.

Therefore, the spring 31 has one end connected to the inner cylinder 29.
The other end is a leaf spring that is fixed to the inner surface of the outer cylinder 34 and the other end is pressed against the inner surface of the outer cylinder 34.

Further, a tapered portion 34c is formed at the front portion of the outer cylinder 34 to fit into a tapered recess 9a at the tip of the bobbin holder 9 of the winding machines 3, 4.
7, when the outer cylinder 34, which is moved forward to the left in FIG. 6), the bobbin holder 9 and the outer cylinder 34 are arranged in a straight line.

41 is a window hole 34d made at the tip of the outer cylinder 34
It is a leaf spring provided so that its elastic end 41a projects outward in the radial direction, and the elastic end 41a presses the inner surface of the paper tubes 8a and 8b outward through the window hole 34d, thereby holding the paper tubes 8a and 8b. The paper tubes 8a and 8b are stabilized.

The drive device 37 of the shaft 32 is connected to the truck body 1.
4, and the output pinion gear 3 connected to its output shaft 43 via a torque limiter 44 as an overload release device.
However, by installing a torque limiter 44, the reversible motor 42 can be used when the shaft 32 moves to the left in FIG. By continuing to rotate in the direction, even if the distance between the outer cylinder 34 and the bobbin holder 9 is indefinite, the outer cylinder 34 can be reliably butt-fitted to the end of the bobbin holder 9. When the outer cylinder 34 is moved to the right in FIG. 6 and pulled out from the bobbin holder 9, this can be done by continuing to rotate the reversible motor 42 in the opposite direction.
Therefore, an appropriate clutch or the like may be used in place of the torque limiter 44.

Next, the extrusion plate 27 for extruding the paper tubes 8a, 8b from the outer cylinder 34 and its drive mechanism 28 will be explained. It is supported by a horizontal pin 47 protruding from a nut block 46 so as to be freely movable back and forth (left and right in FIG. 6).
It is a letter-shaped plate member, and is always biased forward (to the left in Fig. 6) by a compression spring 48 interposed in a horizontal pin 47, and is also able to rotate freely around the horizontal pin 47. Due to the weight of the extrusion plate 27 itself, a moment is applied in the direction of arrow A in FIG.

The drive mechanism 28 includes the ball screw 45, a nut block 46, and a reversible motor 5 connected to the end of the ball screw 45 via a torque limiter 49.
1, and the start/stop control of the reversible motor 51 is performed by the dog portion 4 of the nut block 46.
of the limit switches 52 and 53 that 6a engages with.
Although it is controlled by ON/OFF, the position of the limit switch 52 on the front side is set as follows.

That is, when the pushing plate 27 hanging down from the nut block 46 pushes the paper tubes 8a, 8b to the bobbin holder 9 of the winding machines 3, 4 due to the movement of the nut block 46, the paper tubes 8a, 8b are not wound up. The position of the limit switch 52 is such that the extrusion plate 27 on the nut block 46, which has moved to the position where the limit switch 52 is kicked (end position), is completely transferred to the machines 3 and 4. paper tubes 8a, 8 in a state where it is greatly reduced.
The position is such that it is in pressure contact with the b end face. In other words, the length of the movement stroke of the nut block 46 is approximately the sum of the length of the compression spring 48 and the length sufficient to transfer the paper tube toward the winding machine.

The upper part of the nut block 46 has a fork shape divided into two parts, and the ball screw 4
A rail member 14a protruding from the truck body 14 in parallel with the nut block 46 is sandwiched between the fork-shaped portions to prevent rotation of the nut block 46.

Further, a tapered portion 34e is formed at the tip of the outer cylinder 34 to serve as a guide when paper tubes 8a and 8b are inserted from paper tube supply devices 5 and 6, which will be described later.

Next, the receiving device 7 for a full package will be described. The receiving device 7 in this example includes a creel cart 81 with 16 pegs 13 protruding in a substantially horizontal direction, and a creel cart 81 that moves up and down to two height levels. The lifter device 82 is provided in a pit 83 formed in the floor, and when the creel truck 81 is lifted, the wheels of the creel truck 81 and the floor surface are on the same level as shown in the second figure. Thus, the creel truck 81 can be carried in and out freely, and when the lifter device 82 is lowered to lower the creel truck 81 to a lower level, the lower part of the creel truck 81 enters into the pit 83.

Then, at the raised position (Fig. 2) of the creel trolley 81, the full package P is delivered from the mobile trolley 1 to the four pegs 13 in the second stage from the top and the four pegs 13 in the lowest stage, and then at the lowered position. In this case, a full package P is delivered from the movable cart 1 to the four pegs 13 on the top tier and the four pegs 13 on the third tier from the top.

Note that the creel truck 81 has a lifter device 82.
After arriving at the top and being positioned, it is fixed at a predetermined position by a position fixing device (not shown), and after the fixing device is removed, it can be moved freely. may be of the type that runs on rails, or may be of a trackless type guided by appropriate guidance means.

Next, the operation of the above-mentioned embodiment system will be explained. The paper tube feeding devices 5, 6 of the moving cart 1 and the full package receiving device 7 are all controlled by a central control computer, as follows. Operate.

That is, the paper tubes 8a to be applied to the spinning take-up machine 3 on the left side in FIG. 8b is stored in the paper tube supply device 6 on the right side, for example, when a winding completion signal is input to the control computer from the winding machine 3 side,
In response to this signal, the mobile cart 1 immediately moves to the paper tube supply device 5, and from this device 5 a paper tube 8 for the winding machine 3 is delivered.
a onto the paper tube transfer device 11, and moves to a predetermined position of the bobbin holder 9 of the winding machine 3 while holding the received empty paper tube 8a.

At this time, the positioning of the movable carriage 1 is performed using the above-mentioned positioning device 15, and detection and deceleration of the stop position are detected and controlled by a proximity switch on the carriage 1 and a dog on the rail 2 (not shown).

The extrusion device on the winding machine 3 side operates to transfer the full package P to the cart 1, which is positioned so that the full package transfer device 12 faces the predetermined position of the bobbin holder 9, and then the cart 1 is moved over a short distance. After the movement, the bobbin holder 9 and the paper tube transfer device 11 are now positioned at opposing positions.

Then, the paper tube transfer device 11 operates as described above, that is, the outer cylinder 34 holding the paper tube 8a is first fitted and connected to the bobbin holder 9 to form a straight line, and then is pushed out by the extrusion plate 27. Bobbin holder 9 with empty paper tube 8a
handed over to.

At this time, even if there is an error in the opposing relationship between the bobbin holder 9 and the paper tube holding shaft 26 within the positioning accuracy of the trolley 1, if the outer cylinder 34 moves toward the bobbin holder 9, it will work as described above. The outer cylinder 34 is slightly movable in a vertical plane, and the tapered portion 34c at the tip of the outer cylinder 34 is tightly fitted into the tapered recess 9a of the bobbin holder 9, so that the outer cylinder 34 is attached to the bobbin holder 9. Even if the diameter of the bobbin holder 9 and the inner diameter of the paper tube 8a are approximately equal, the paper tube 8a can be transferred smoothly. Further, the extrusion plate 27 also freely swings around the pin 47, following the movement of the outer cylinder 34, and moving the paper tube 8.
It does not come out of contact with the a end face.

The mobile cart 1, which has delivered the empty paper tube 8a and received the full package P, then moves to the receiving device 7 position for the full package P, and has already moved to either the raised position or the lowered position according to a command from the control computer. The leveled creel truck 81 stops at a predetermined peg 13 position, and the extrusion block 2
5 moves forward and places the full package P on the predetermined peg 13.
pass it on to

Transferring the full package P, paper tube transfer device 1
1. The empty mobile cart 1 together with the transfer device 12 for the full package P returns to the paper tube supply device 5, 6 position (neutral position) shown in the second figure, and one cycle is completed.

[Effect of idea]

As is clear from the above explanation, if the paper tube delivery device according to this invention is used, there are multiple bobbin holders to be delivered, and each bobbin holder has a different position, length, etc. Also, the paper tube can be pushed and transferred to the optimal position at the innermost part of the bobbin holder.

Therefore, the subsequent winding operation with the winding machine can also be performed smoothly and favorably.
