Abstract

PURPOSE:To make an uncollapsed solid thread ball securable with using no force in time of taking a bobbin winder body for the solid thread ball out of a bobbin winding part, by making up a split hollow shaft for a built-up bobbin so as to come into a state of being diametrally expanded in time of assembling and also into a state of being diametrally contracted in prototype in time of disassembling. CONSTITUTION:After manufacturing a bobbin winder body which winds up thread in a specified quantity and forms a solid thread ball, a presser shaft 20 is made to go up, and a bobbin pressing head 22 is separated from a flange 62 of a built-up bobbin 30, taking out the built-up bobbin fitted with a bobbin winder body, and a center pin 70 is pulled out of both of a radial hole 52 of a split hollow shaft 44 and a through radial hole 66 of a tapered arbor 64, then this tapered arbor 64 is pulled out of a taper shaft hole 60 of a main half-bobbin 40 through pushing pressure in the tip end part, and with this method, the split hollow shaft 44 is contracted up to a prototype state as leaving an elastic ring 48 energized intact whereby in the shape of what engagement with the solid thread ball is fully cut off, the soid thread ball carrying an in-and-out through hole is made possible to be taken out at a position opposed to the diametral direction, thus slough-off in a yarn layer is brought to nothing at all.

Description

DETAILED DESCRIPTION OF THE INVENTION As disclosed in, for example, Japanese Utility Model Publication No. 45-28596, the number of traverse windings in both halves in the axial direction is the same, and there is a The present invention relates to an improvement of a bobbin winding mechanism installed in parallel with a traversing mechanism in a bobbin winding machine for producing a coreless ball of yarn having through holes.

This type of bobbin winding mechanism is known as Utility Model 45-57590
As disclosed in the No. 1 publication, etc., a conventional ζ-ring consists of a part of the main shaft and is arranged in a tapered retractable bobbin part so that it can be moved in and out with a center pin for forming an inner and outer through hole. In this conventional spool winding mechanism, the thread body constituting the uncore yarn wound on the bobbin part and the bobbin part are not fully released from each other, so the thread body cannot be taken out smoothly. However, there is a problem in that the wound yarn layer easily collapses.

In view of the above-mentioned problems observed in conventional ones, the bobbin winding mechanism according to the present invention is capable of taking out the bobbin body constituting the fabricated uncore yarn ball from the bobbin winding section in a manner that does not cause yarn breakage. It was devised with the main purpose of making it possible.

The bobbin winding mechanism according to the invention includes a main shaft having a bobbin receiving head at the tip thereof, and a bobbin receiving head that is disposed at the front of the main shaft concentrically with the main shaft and capable of approaching and separating from the main shaft. It consists of a suppressing shaft having a rotatable bobbin suppressing head, a clamp I and an assembled bobbin between the bobbin receiving head of the main shaft and the bobbin pressing head of the pressing shaft, and the assembled bobbin is secured to the bobbin receiving head. A biological bobbin with a split hollow shaft that is biased radially inwardly (in the closing direction) through a possible flange and an elastic member and has a radial hole (large diameter) in the axially central part; A secondary bobbin, which has a flange that can be attached to the head and a centering motion that can be fitted into the shaft hole of the split hollow shaft of the biological bobbin and has a diameter larger than the diameter of the shaft hole of the split hollow shaft, is attached to the split hollow shaft. The center pin is inserted into the shaft hole and assembled with the split hollow shaft expanded outward in the radial direction (6), and the center pin is fitted into the radial hole of the split hollow shaft. It has become.

In the bobbin winding mechanism according to the present invention, the thread is generally guided through a traversing mechanism to the assembled bobbin rotated through the main shaft, while the hollow shaft of the biological bobbin is expanded outward in the radial direction. After winding a predetermined amount of yarn on the bobbin, the suppression shaft is separated from the bobbin receiving head of the main spindle, and the assembly pobbin having the winding body that forms the uncentered yarn ball is taken out. At the same time, by removing the center movement of the secondary bobbin from the shaft hole of the split hollow shaft of the biological bobbin, the split hollow shaft of the biological bobbin is removed from the radially outward expanded state of the elastic member. Contract while maintaining the biasing force. By this method, a completely free ball of yarn can be obtained.

In the bobbin winding mechanism of the present invention, in order to facilitate the assembly and disassembly of the biological bobbin and the secondary bobbin, the shaft hole of the split hollow shaft of the former is preferably made into a tapered shaft hole with a thick tip (originally thin), and the shaft hole of the latter is made into a tapered shaft hole. The heart movement is a tapered Theba (4) heart movement.

In addition, in this bobbin winding mechanism, in order to make the assembly of the center pin into a solid form, a radial hole into which the center pin fits is provided in the center of the first sub-half bobbin, so that the center pin can be attached not only to the split hollow shaft of the biological bobbin. It can also be made to engage with the heart motion of the secondary bobbin.

Next, the illustrated embodiment will be described.

The illustrated bobbin winding mechanism can be said to be vertical, and has a rotatable bobbin pressing head (A) at the lower end directly above the main shaft αQ having a bobbin receiving head (6) at the upper end via a bracket (A). ) is supported so as to be able to move up and down while being biased downward via a spring ■, and between the bobbin receiving head @ of the spindle head and the bobbin pressing head @) of the pressing shaft ■, there is a Bobbin - 1 secondary half bobbin clause and center pin (7
It consists of a structure in which an assembly bobbin (2) containing 0 is held between the bobbins.

The biological bobbin 10 forming the assembly bobbin (to) has a flange (1) that engages with the bobbin receiving head (6) of the spindle head, a flange (6) that extends outward in the radial direction, and a 114ii Z It is equipped with a hollow shaft (goods) divided into four parts, and the hollow shaft (b) inserts an elastic ring into the circumferential groove (g) provided in the flange-like base located inside the flange (6). As a result, it is biased inward in the radial direction to assume a closed (original shape) state, and the tapered shaft hole is diametrically opposed at approximately the center in the axial direction. It has a pair of radial holes.

In addition, the secondary bobbin... has a flange that engages with the bobbin pressing head (a) of the pressing shaft ring, and a flange that protrudes from the flange (J to form an annular groove around the base, and is located in the middle part in the axial direction. For the bank bobbin 140, it is equipped with a tapered six-shaft shaft 61 having a diameter larger than the diameter of the bank bobbin (the tapered shaft hole of the current Gekichu-Korasha Co., Ltd.). Tapered 6-axis - hollow axis (
For the tapered shaft hole of the flange U, the tip thereof protrudes from the end face of the flange U, and the through radial shaft E is fitted so as to communicate with the pair of radial holes. It is assembled while expanding outward and at the same time holding its tip in the annular groove.

The center pin (7 [phase] passes through the 6 radial holes provided in the bank bobbin u0 and secondary bobbin... and the Zaizu radial hole - to the hollow shaft in the play) at a position opposite to the radial direction. It is assembled so that it protrudes towards the side.

The illustrated peg mechanism is the main! 1 While rotating the assembled bobbin (to) held between the bobbin receiving head OA of the moe and the bobbin suppressing head holder of the suppressing shaft ring through the rotation of the main moe, rotate the assembled bobbin (to) in the radial direction. After winding a predetermined amount of yarn to create a winding body that forms a thread ball, the compression m (a) is raised against the old force of the gene (c) to create a bobbin compression. Assemble head (2) and bobbin 0
Separate it from the flange 1'4 of the by-product bobbin whale 1, take out the assembled bobbin (7) with the winding body, and then insert the center pin (7 side is inserted into the radial hole 6 of the hollow shaft ■) and the taper. After pulling it out from the through-radial hole of the 6-shaft (7), the tapered 6-shaft 1→ of the secondary bobbin is inserted into the main half bobbin 1 through the suppression of the tip protruding from the end face of the flange 69. By removing the hollow shaft of the hollow shaft from the tapered shaft hole, and thereby contracting the hollow shaft n4 to its original size while retaining the bias of the elastic ring ■, the engagement with the free thread ball is completely eliminated. In the form of cutting off
To freely take out a coreless yarn ball having inner and outer through holes at positions facing each other in the diametrical direction.

As is clear from the above explanation, with the 2t bobbin winding mechanism according to the present invention, the hollow shaft of the assembled bobbin constituting the bobbin section is enlarged in diameter to V when assembled, and reduced to its original shape when disassembled. Since it was configured to be in a radial (menopausal) state,
It is possible to take out the bobbin body that forms the uncorked yarn ball from the bobbin winding section without applying any force to the wound yarn, and therefore, it is possible to obtain a uncorked yarn ball without any deformation of the wound yarn. Moreover, useful effects are produced.
