Abstract

Center material(C) is supplied by adf driving roller(4) and a pressing roller(5). (C) is passed through a guiding hole(19) of a reciprocating shaft(16) and is delivered to the element forming device(1). The feeding device(4,5) is driven faster than the element forming velocity. (C) is maintained in the guiding hole by the friction between a bent of guiding hole and (C). And it is delivered to the element forming device by the ascending of the holder. This prevents the extension of (C) and delivers it sufficiently. Since the drawing process by the feeding device is separated from the delivering process, the condition of the processes can be controlled.

Core material supply device for coiled fastener element manufacturing

2 is an explanatory diagram showing a process of the present invention.

3 is a partial cutaway view of the main portion showing the outline of the device.

4 is a front view showing the core material transfer mechanism.

The present invention relates to a device for supplying a core material in the manufacture of a coiled fastener element through which a core material is inserted therein, and an object thereof is firstly to provide an apparatus for supplying a core material of a requisite amount in a loose state to an element forming process, Second, to provide a supply device that can adjust and limit the supply of core material with a simple mechanism.

Previously known types of core material supply devices, such as those disclosed in Japanese Patent Application No. 46-1132 and Japanese Patent Application No. 45-40939, show that the core guide rollers swinging from side to side in accordance with the shanghai-dong of the mandrel holder are formed. It is installed between the core member and the core member, and the core member is configured to take the core member out of the core member by the left and right movement of the core guide roller, so that the tension member acts on the core member so that the core member is in a taut state. Feed rate is not sufficient when forming elements.

In addition, since the heartwood is pulled by the left and right swing of the heart guide guide roller and pulled out of the heartwood storage unit, the amount of drawn heartwood is uneven. When attaching the coiled fastener element containing the core material to the tape with the sewing machine, in general, since the sewing thread penetrates the core material, the core material bends or swells due to the passage of the sewing thread and the sewing needle, and the sewn core material is in the coil element. As it is reduced, it needs to be inserted further into the element by that reduced amount.

In addition, according to the prior art as described above, it was difficult to adjust the amount of core material conveyance because each of the core material is pulled out and sent to the shandong east of the core rod holder.

For example, when the material or structure of the core material is changed, the contact friction force between the core material and the inner wall of the core guide hole changes, and accordingly, the amount of the core material conveying is insufficient, and thus, fine adjustment for adjusting the excess or insufficient is difficult.

The present invention has been made in order to solve the various defects as described above, embodiments of the present invention will be described in more detail with reference to the drawings. Between the element shaping mechanism 1 and the core material storage part 2, the core material delivery mechanism 3 which is forcibly pulled and conveyed the core material C from the storage part 2 is provided. The core material transfer mechanism 3 is formed of a drive roller 4 and a presser roller 5 pressed against and in contact with the drive roller 4, and the drive roller 4 and the pressure roller 5 are respectively placed together. The depressed gears 6 and 7 are fixed. The presser roller 5 is axially fixed to an arm 9 axially fixed to the frame 8. The other end of the arm 9 is connected to the frame 8 with the spring 10 and is always pushed by the drive roller 4 axis, and is configured to move along the drive roller 4. .

On the other hand, the ratchet wheel 12 is fixed to the shaft 11 to which the drive roller 4 is attached, and the swing lever 13 which moves and swings according to the element forming mechanism 1 is fixed to the shaft. It is. The ratchet 14 coupled to the ratchet wheel 12 is axially fixed to the swing lever 13, and the drive roller 4 is intermittently operated by swinging the swing lever 13. In this case, the rotational speed of the drive roller 4 is adjusted to rotate slightly faster than the element forming speed.

Next, the sleeve 15 is fixed to the frame 8, and the sliding shaft 16 is fitted to the fixed sleeve 15, and the mandrel holder 17 is fixed to the distal end thereof. The mandrel holder 17 and the sliding shaft 16 move in accordance with the operation of the screw 18 of the element forming apparatus 1 to perform the forward retreat movement.

In addition, the sliding shaft 16 and the mandrel holder 17 have a guide hole 19 through which the core C is guided and passed, and the mandrel holder 17 is guided in the center of the sliding shaft 16. A guide hole 19, which is connected to the hole 19, is drilled upwards along the mandrel 20, from the center of the holder 17 towards the surface and towards the center. The guide hole 19 in this case is formed so that contact friction may arise with respect to the core material guided by the obtuse angle. 21 is a pipe for guiding the core C from the core transfer mechanism 3 to the guide hole 19 of the sliding shaft 16, and the brake E is a fastener element.

The present invention has the above-described configuration, and the action is first performed by the core material C in the core material storage part 2 by the operation of both rollers by forcing the core roller C between the driving roller 4 and the pressure roller 5 by a necessary amount. Are transported by drag. Next, the core material C is introduced into the guide hole 19 of the sliding shaft 16 reciprocating through the guide pipe 21, and is conveyed to the element forming mechanism 1 from the upper surface of the holder 17.

In the present invention, the core material supply means is a feed mechanism of the drive roller and the pressure roller is operated at a speed slightly faster than the element forming speed to forcibly pull out the core material of the required amount, the core material guide hole of the core rod holder which is a movable body Since the core is supported in the guide hole by the frictional force between the curved guide hole wall surface and the core, and the core is conveyed to the element forming mechanism by raising the core holder which holds the core, the core to be conveyed has a tensile force. It can be conveyed in a loose state without being applied at all, and it can supply the necessary and sufficient core material in the element.

Since the core material extraction process by the core material transfer mechanism and the core material conveyance process by the reciprocating motion of the core rod holder are separated, the core material transfer amount can be easily adjusted in the core material extraction process. In addition, the core material can be adjusted in an accurate and loose state by adjusting the amount of core material drawn out in the core material extraction process, which provides the advantage of providing highly accurate core material.
