Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an automatic winding machine for tapes, strings, etc.

In automatic winding machines that normally wind tapes, strings, etc. onto a rotating bobbin to form a bundle, the tape, strings, etc. are wound uniformly onto the rotating bobbin via a traverse means. Conventional traverse means include one that positions and supplies tape, string, etc. with the tip of a swinging arm that is pivoted at one point, and one that positions and supplies tape, string, etc. with the tip of an arm that can reciprocate along a rotating bobbin. However, these conventional traverse means swing or reciprocate only within a certain preset range, and wind up the tape, string, etc. on the rotating bobbin within that range. Since it is a type of paper, there is an inconvenience that only a certain winding width can be obtained.

Note that there is known a device (Japanese Utility Model Publication No. 53-31013) in which a traverser is rotated in the forward and reverse directions using a set of limit switches and a drive device controlled by signals from the limit switches.

However, although this device is suitable for winding wires and cables in an aligned manner, it cannot be applied to automatically winding up tapes, strings, etc.

Therefore, the present invention has been developed in view of the above points, and the traverse means is provided with a variable-position limit switch, and the winding width can be set and adjusted by this limit switch, thereby providing diversity in the winding width. The purpose of the present invention is to provide an automatic winding machine for tapes, strings, etc., which can be made to stand upright.Specifically, the lower end has a vertical shape that can be contracted and restored, and the tape, strings, etc. can be rolled up on the outer circumferential surface thereof. The winding width is set between a rotating bobbin that forms the bundle, reduces its diameter, and then drops the bundle, and a pair of variable-position limit switches.
a traverse means, which is adjustable and capable of reciprocating through a clutch capable of forward and reverse rotation, for uniformly winding tape, string, etc. to a desired winding width around the outer periphery of the rotary bobbin; tape, distracting from the bundle;
It is an object of the present invention to provide an automatic winding machine for tapes, strings, etc., comprising a heat cutter with a rotatable cutter arm disposed below the rotating bobbin to cut a desired portion of the strings, etc. .

The details will be explained below based on the illustrated embodiment.
The figure shows a schematic front view of an automatic winding machine for tapes, strings, etc. according to the present invention, and this self-winding machine for tapes, strings, etc.
It mainly consists of a rotating pobbin 1, a traverse stage 2, and a cutter means 3.

The rotating bobbin 1 is vertically supported via a bearing 4 at the upper part,
In addition, the main shaft 6, which is rotatable by the motor 5, has a Boo'J-
7a, 7b and are connected via a belt 8 so as to be freely rotatable.

The rotary bobbin 1 is formed of a plurality of divided pieces 9, and has a bobbin opening/closing shaft 11 inserted therein and movable forward and backward by a cylinder 10.

This bobbin opening/closing shaft 11 has at its tip a force ram 12 for reducing the diameter and restoring the lower part of the rotating bobbin, and a bobbin stopper 13 that can freely protrude toward the surface of the rotating bobbin to prevent the winding from falling off.

Furthermore, the rotating bobbin 1 is provided with a guide roller 14 for correcting the winding.
are placed close together.

The guide roller 14 is always urged toward the rotating bobbin 1 via a spring means (not shown), so that it can come into contact with the winding surface.

The 1,000-stage traverse 2 includes a traverse arm 15 that can freely reciprocate along the longitudinal direction of the rotating bobbin (vertical direction in the illustrated example) by a reciprocating means 16.

The traher arm 15 is slidably supported by the guide shaft 17 at the base end side, and the tip 18 is always urged toward the rotating bobbin side via a spring means (not shown). It is designed to position and supply strings, etc.

The reciprocating means 16 includes a chain 19 connected to the traverse arm 15, a clutch 21 connected to the main shaft 6 via a gear 20 and capable of rotating the chain in forward and reverse directions, and a reciprocating movement limit position of the traverse arm 15. It has micro switchers 22 and 23 as a pair of limit switches for detecting and instructing switching of the clutch 21.

The microswitches 22 and 23 are supported by the microswitch adjustment shaft 24 and are connected to the microswitch adjustment shaft 24.
The upper position is variable (in the example shown, the lower microswitch 23
is fixed, and the upper microswitch 22 is variable in position.

], both microswitches 22 and 23
By adjusting the position, the reciprocating interval of the traverse arm 15 is adjusted, and the winding width W of the winding bundle 25 on the rotating bobbin 1 is adjusted.
can be set and adjusted freely, which is a major feature of the present invention.

In the figure, 26 is a balancer provided on the chain 19, 31 is a guide coil for tape or string, and 32 is a guide piece provided at the tip of the traverse arm.

The cutter means 3 is located below the rotating bobbin 1 and cuts tapes, strings, etc. when the wound bundle is removed from the rotating bobbin 1, and includes a rod-shaped heat cutter 27 fixed in position.
It consists of a frame-shaped cutter arm 28 that brings tape, string, etc. into contact with the heat cutter 27.

This cutter arm 28 is rotatable via a cutter arm drive gear 30 connected to an air cylinder 29.

Although this cutter means cuts tapes, strings, etc. by heating, the present invention is not limited to this, and any cutter means having a cutting blade may be used.

Next, the action will be explained.

First, tape, string, etc. are attached to the guide coil 31. Guide bead 32 of traverse arm 15 and guide roller 1
4 and its tip to the rotating bobbin 1 in a counterclockwise direction (the 4th
(Fig.) and adjust the upper microswitch 22 by moving it on the microswitch adjustment@24 to obtain the desired winding width W.
Set to .

Next, when the motor 5 is driven, the rotating bobbin 1 and the traverse stage 2 are operated as the main shaft 6 rotates, and winding of tape, string, etc. is started.

At this time, the rotation of the traverse means 2 is transmitted from the main shaft 6 to the chain 19 via the gear 20 and the clutch notch 21, and the rotation of the chain 19 causes the traverse arm 15 to move along the guide shaft 17, and both microswitches 22 At .23, both limit positions of the reciprocating motion of the traverse arm 15 are detected, and at that position, the clutch 21 is switched to forward or reverse rotation to cause the traverse arm 15 to reciprocate within the desired setting range of the microswitches 22 and 23. Then, tape, string, etc. are uniformly wound onto the rotating bobbin 1 from the tip of the traverse arm 15 to a desired winding width W.

Further, during winding, the guide roller 14 is constantly pressed against the surface of the bundle to correct and smooth the state of the bundle, so that a uniform and firm winding can be obtained.

When the winding is finished, the air cylinder 10 is operated to reduce the diameter of the lower part of the ten rotating bobbins, the bobbin stopper 13 is set in a non-projecting state, the winding bundle 25 is dropped, and a cutter is operated to cut tape, string, etc. Then, the cut portion is wound again around the rotating bobbin 1 and the winding process is repeated.

Also, when changing the winding width, use the Kamigori micro switch 2.
Stepless winding width can be obtained by simply changing the position of 2)
It is extremely good.

As explained above, when the automatic winding machine for tapes, strings, etc. according to the present invention is used, there are many effects as listed below.

(a) The lower end has a vertical shape that can be reduced in diameter and restored, and a rotating bobbin is provided on the outer circumferential surface of the bobbin to form or reduce the diameter of a bundle of tape, string, etc. and drop the bundle. The process of forming the bundle, dropping it, removing it, re-winding it, etc. can be performed automatically and efficiently, and the winding width is set between a pair of limit switches with variable positions. - A traverse means is provided on the outer periphery of the rotating bobbin to uniformly wind up tape, string, etc. with a desired winding width, so that the rotating bobbin It is possible to supply tape, string, etc. in an appropriate condition and wind it up uniformly with any desired winding width, and (c) the desired part of the tape, string, etc. can be stretched from the wound bundle that has fallen from the above-mentioned rotating bobbin. A heat cutter with a rotatable cutter arm was installed below the rotating bobbin in order to cut the bobbin, so that by rotating the cutter arm,
A certain part of the tape, string, etc. that has been stretched out from the fallen bundle can be manually pulled together and cut with a heat cutter reliably and safely, making it easier for the rotating bobbin to wind up again. D) Since the guide roller is disposed close to the rotating bobbin and biased against the winding surface, it is possible to obtain a firm winding while leveling the winding surface uniformly.
