Description

[Detailed explanation of the idea] The present invention relates to a tube conveying tray.

In conventional trays, in which the lower end surface of the yarn is placed on a stand that stands upright in the center of the tray, which is used as a conveyance medium for the yarn used when conveying the yarn for spinning, the yarn is placed on a peg. The posture of the tube and yarn was unstable when it was inserted and placed on the stand, and it wobbled during transportation. Therefore, when it is desired to chuck the yarn with a yarn gripper, for example, the yarn is tilted or wobbly at a predetermined position, making it impossible to accurately position the yarn, resulting in a chuck error.

Furthermore, if the inner diameter of the lower end surface of the tube is inserted into the peg, the posture of the tube becomes more unstable. It was impossible to do so. Furthermore, for the same reason as mentioned above, slight deformation of the lower end surface of the tube has had an adverse effect on the posture stability of the tube or the insertion of the tube into the peg.

The purpose of the present invention is to solve the above-mentioned problems. That is, at least the part of the peg of the tray where the lower end surface of the pipe thread contacts is formed with a taper whose diameter increases as it goes toward the disc-shaped base. This is what I did.

Hereinafter, an example of implementation of the present invention will be described based on the drawings.

FIG. 1 shows a tray 1 according to the present invention in which a tube 2 is inserted. That is, the tray 1 is formed by integrally molding or fixing a disc-shaped base 4 to be placed on a conveyor 3 and a peg 5 standing upright in the center of the top surface of the base 4, with an opening 6 at the inner bottom. , communicates with the hollow circular portion 7 of the peg 5, and a hole 9 for blowing out air is bored in the apex slope 8 of the peg 5.
In addition, in the pipe thread 2 inserted into the peg 5, 10
11 indicates a core tube, 11 indicates a center hole formed by the core tube 10, and 12 indicates a yarn end pulled out from the tube yarn 2 when tying the yarn. It has a trapezoidal shape that is slightly larger than the diameter of the upper end surface.

The structure of the peg 5 will be explained in detail based on FIG. 2. That is, the peg 5 consists of the apex slope 8, the cylindrical part 13, and the root part 14,
The root portion 14 has a taper t whose diameter increases toward the disk-shaped base 4. The above cylindrical part 1
3, the outer diameter b of the lower end surface of the root portion 14, and the tube thread 2.
When comparing the inner diameter c of the lower end surface 16, the root portion 14
is a taper t whose diameter increases as it approaches the disc-shaped base 4, and since the lower end surface 16 of the tube thread 2 is located at the taper t of the root portion 14, the following relationship is satisfied: a〓c〓b Set. Further, the taper angle θ of the root portion 14 is set in the range of 15 degrees〓θ〓30 degrees, and the outer diameter a of the cylindrical portion is set at the position where the cylindrical portion 13 is closest to the core tube 10, that is, A boundary portion 15 between the apex slope 8 and the cylindrical portion 13 is set to have a small distance d from the core tube 10 . Note that the height h1 of the root portion 14 is calculated from the values of a, b, and θ described above.

Also, if the taper angle θ is 15 degrees or less, the pipe thread 2
If the angle is 30 degrees or more, the stability of the posture of the thread 2 will be lost.

The yarn 2 is inserted into the peg 5 of the tray 1, the lower end surface of the yarn is supported by the taper t of the base 14, and the yarn is conveyed integrally with the tray in an upright position. The yarn end 12 pulled out from the tube 2 is inserted into the center hole 11 of the core tube 10 from the upper end of the tube and suspended. When tying the thread, air is ejected from a nozzle at a predetermined position of the winding unit from the internal space 7 of the tray and into the center hole 11 of the core tube 10 through the hole 9 of the peg 5, thereby tying the hanging thread end 12. It pops out upward from the center hole 11 and is absorbed and grasped by the waiting suction arm.

In addition to this example, the third example provides the following examples.
The figure shows a tray in which the cylindrical portion of the peg 5 is also tapered at the same angle as the root portion 14. but,
In the embodiment shown in FIG. 3, the distance d between the peg 5 and the tube thread 2 increases, and it cannot be said to be a preferred embodiment, but it shows that the present invention does not specify the height h2 of the base. ing. FIG. 4 shows an embodiment in which the root portion 14 of the peg 5 is made up of a tapered T portion and a base portion 17. In the present invention, at least the portion of the peg 5 that contacts the lower end surface 16 of the pipe thread is tapered T. This indicates that it is sufficient if the

As described above, according to the present invention, at least the part of the peg that the lower end surface of the tube comes into contact with is tapered so that the diameter increases as it goes toward the disc-shaped base, so that the lower end surface of the tube yarn is formed at the taper of the peg. Since it is completely gripped not only in the vertical direction but also in the horizontal direction, there is no wobbling of the lower end surface of the tube, and the posture of the tube can be maintained stably. Therefore, when the head of the pipe is checked with a pipe gripper or the like, the pipe is positioned at an accurate position and chuck errors are eliminated. In addition, when splicing yarn in the winding unit, the end of the yarn inserted into the center hole of the tube yarn is blown up by compressed air from below the tray, and is sucked and grasped by the suction arm waiting above. Also, the yarn end can be blown up to a predetermined opening position of the suction arm along the axial direction of the yarn center hole, and gripping errors can also be prevented. Furthermore, theoretically speaking, all tube yarns having an inner diameter of the lower end surface that is larger than the minimum diameter of the tapered part and smaller than the maximum diameter can be used in the tray of the present invention, but in reality, the pegs at the peg tip can be used. The types of tubes that can be used are somewhat limited due to the difference between the outer diameter and the inner diameter of the tube, but it is no longer the case that only one type of tube can be used for a given tray, as was the case in the past. . Furthermore, even if the lower end surface of the yarn is deformed, as long as the tapered part of the peg and the yarn are in contact at at least three points, it is possible to keep the posture of the yarn stable. It has a long lifespan and is economical. In addition, the entire peg is cylindrical (for example, the
127051), there is a gap between the entire area of the peg and the inner peripheral surface of the core tube, so the vibration when stopped is difficult to stop. However, in the tray of the present invention, at the upper end of the peg, there is a gap d between the peg and the inner peripheral surface of the core tube, as shown in Figure 3, but at the lower end of the peg, there is a gap because the core tube is supported by the tapered part. Because of this, when the tubing yarn integrated with the tray is conveyed and stopped at a certain position, the vibration of the tubing yarn caused by the inertia force or impact at the time of stopping stops immediately, and the subsequent processing of the tubing yarn is stopped. You can start faster and process faster.
