Abstract

PURPOSE:To realize a simple structure and a smooth operation to prevent loosening and tangle at the end of winding, by furnishing a rotary transfer plate to transfer a wound up bobbin and to stop a vacant bobbin, and a delivery route in a circle arc form with a friction portion. CONSTITUTION:A rotary transfer plate 11 is furnished at the down stream side of a bobbin holding board 2, to receive a bobbin wound up at the winding position A, and deliver it to a bobbin exhaust route 12. Moreover, as well as furnishing a delivery route 21 in a circle arc form responding to a locus of the tip of the rotary transfer plate 11, a friction portion 23 is arranged in the delivery route 21 where the wound up bobbin 5 contacts and rolls along. The rotary transfer plate 11 is used concurrently as a stopper to stop a vacant bobbin being fed, with its upstream side end 11a projected higher than the bobbin holding board 2, in a condition of a specific angle turned around II. Thus, a simple structure, a smooth operation, and a lower rate of system trouble are realized, as well as preventing loosening and tangle at the end of wound up thread.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an empty bobbin to a winding position where a filament is wound, and a fully wound bobbin on which a filament is wound at the winding position. The present invention relates to a bobbin supply and discharge device that transfers and discharges a bobbin to a lower bobbin discharge path.

[Conventional technology and its problems]

Conventionally, a vertically standing screw shaft is driven to rotate, and a mounting table on which a fully wound bobbin is placed is reciprocated in a straight line up and down, thereby transferring the fully wound bobbin from the upper bobbin supply path and winding position to the lower bobbin discharge path. The winding bobbin was being ejected. Therefore, there were problems in that the structure became complicated and the failure rate was high.

An object of the present invention is to solve these problems and to simplify the structure, smooth the operation, and reduce the failure rate. Still another object is to prevent the winding end of the filament wound on the fully wound bobbin from unraveling and tangling in the discharge path.

[Means for solving problems]

The bobbin supply and discharge device of the present invention has a rotary transfer plate that receives the fully wound bobbin at the winding position and transfers it to the bobbin discharge path below, on the downstream side of the bobbin support stand at the winding position. Further, an arcuate transfer path corresponding to the locus of the tip of the rotary transfer plate is provided, and a friction portion on which a fully wound bobbin contacts and rolls is provided in the transfer path, and the rotary transfer plate is arranged in a predetermined direction. In the angular rotation state, the upstream end protrudes above the bobbin support base, and the stopper contacts and stops the empty bobbin supplied from the bobbin supply path onto the bobbin support base at the winding position. It is used for both purposes.

[For production]

Since the rotary transfer plate rotates up and down around the horizontal axis and transfers the fully wound bobbin downward, there are fewer moving parts and the number of parts is significantly reduced.

Since the fully wound bobbin is fed out while rotating while moving the friction part of the arcuate transfer path in a fixed direction, the movement is smooth, and the fully wound bobbin can be rotated in a direction in which the winding end of the wire does not unravel. This prevents the wire wound around the bobbin from becoming loose or tangled.

The empty bobbin supplied from the bobbin supply path to the winding position is stopped at the rotary transfer plate itself (upstream end), which further simplifies the structure.

〔Example〕

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

In the side view of FIG. 1 and the plan view of FIG. 2, 1 is a bobbin supply path gently inclined in the downstream direction, and 2 is provided at the downstream end of this bobbin supply path 1 with the same height and slope. The position of this bobbin support stand 2 is the winding position A. The filament 3 sent out from a thin wire drawing machine etc. is transferred to a dancer roll (not shown) in a dancer part of a winding device and a traverse roll 4 in a traverse part.
After that, it is wound onto the bobbin 5 located at the winding position A. Empty bobbins in the standby position (outside the right view of FIGS. 1 and 2) are successively supplied to this winding position from the supply path 1 while moving under their own weight.

As shown in FIG. 2, a bobbin rotation drive body 7 is inserted into the center hole on the side of one collar 6 of the bobbin 5 to rotate the bobbin 5, and a bobbin rotation drive body 7 is inserted into the other collar 6 of the bobbin 5 to rotate the bobbin 5. The winding device has a rotor 8 for holding the press.

Reference numeral 9 denotes a holding plate provided in the shape of an outer flange at the base of the conical bottle lO of the rotary drive body 7, and the filament 3 is clamped and fixed between the flange 6 of the bobbin 5 and this holding plate 9. do.

Reference numeral 11 designates a rotating transfer plate that receives the bobbin 5 fully wound by the winding device and transfers it to the bobbin discharge path 12 below. This rotating transfer plate 11 is provided on the downstream side of the bobbin support base 2. That is, the rotation transfer plate 11 is fixed to a horizontal rotation shaft 13 provided near the downstream side of the bobbin support base 2. A pulley 15 with concave and convex teeth is fixed to one end of the rotating shaft 13 protruding from the side wall 14, and a timing belt 16 is hung on the pulley 15.

On the other hand, 17 is a geared motor, and the timing belt 16 is hung around a pulley 18 with concave and convex teeth fixed to the output shaft of the geared motor, and the rotating shaft 13 is rotated. In other words, as shown in Figure 5,
The rotating transfer plate 11 is rotated counterclockwise at a predetermined angle as shown in FIG. In this state, the upstream end 11a projects upwardly from the bobbin support 2 and comes into contact with the empty bobbin 5 supplied from the bobbin supply path 1 in the direction of arrow B, and the support 2 is not placed on it. The geared motor 17 and the geared motor 17 are moved so that the stopper actuates at the operating position (2), at which the bobbin 5 is stopped at the stopper operating position (2), and the tip thereof rotates the most in the downstream direction, as shown by the solid line in FIG. It is rotated by a drive transmission mechanism including a timing belt 16 and the like.

Further, a proximity switch 19 detects that the rotating transfer plate 11 has rotated to the stopper operating position (2) and issues a signal to stop the motor 17. For example, from pulley 15 to protrusion 2
0 should be provided protrudingly to detect the cracking.

Also, other 1. It is also preferable that each position of II is similarly detected by the proximity switch 19 and the motor 17 is stopped.

Although the bobbin supply path 1 is inclined downward to the left in FIG. 1, and the bobbin discharge path 12 is inclined downward to the right, it can be said that they are arranged substantially parallel to each other at a predetermined distance above and below. By the way, the arcuate moving path 21 corresponds to the locus of the tip 11b of the rotating transfer plate 11.
Establish. The upper end of this transfer path 21 is a vertical portion 22 that is sufficiently higher than the tip 11b of the rotary transfer plate 11 at the bobbin transfer position I, and as shown in FIG.
The lower end of the bobbin discharge path 12 has a height and slope.
Align it with the edge of.

The transfer path 21 is provided with a friction portion 23 against which the collar 6 of the fully wound bobbin 5 comes into contact. Specifically, as shown in FIG. 2, the transfer path 21 is a guide rail made of a pair of angle members, and a band-like body made of a material such as urethane or rubber with a large coefficient of friction is stretched over this guide rail. This is referred to as the friction section 23.

In FIG. 1, the bottle 10, presser plate 9, etc. in FIG. , is located at a higher position by a slight dimension F. Therefore, when pressing from the state shown in FIG. 2, if the bottle 26 of the rotor 8 and the bottle 10 of the rotary drive body 7 are brought close to each other and the bobbin 5 is sandwiched,
Due to the action of the conical tapered surface, the bobbin 5 is lifted by the above-mentioned dimension F, floats up from the support base 2, and becomes freely rotatable.

Moreover, the upstream end 11a of the rotary transfer plate 11, which was in contact with the stopper 7 as shown by the imaginary line in FIG. 1 and the solid line in FIG. 3, becomes floating by a small dimension, and the rotary transfer plate 1! can be rotated in that state.

Further, a bobbin 5 is provided in the vertical portion 22 up to the position shown in FIG.
A detection member 27 and a limit switch 28 interlocked with this detection member 27 are provided for detecting the arrival of .

Here, to replenish the operation of the automatic feeding and discharging device for the bobbin 5 configured as described above, as shown in FIG. is detected and the motor 17 is stopped. Only one empty bobbin 5a at the standby position is fed from the direction of arrow B and stops against the upstream end 11a serving as a stopper.

Next, as described in FIGS. 2 and 1, the pressing is done by the rotor 8.
When the bobbin 5a and the rotary drive body 7 are brought close to each other, the bobbin 5a is lifted by a small dimension F, and becomes floating from the support base 2 and the upstream end 11a. In this state, the filament 3 is clamped and fixed between the collar 6 and the presser plate 9, and can be automatically wound around the bobbin 5a. Next, when the rotary transfer plate 11 is rotated in the direction of the arrow G in FIG. 3 to FIG. Due to the presence of 23, there is little slippage, and it descends while rolling in the direction of arrow M.

In particular, it is important to set the direction of rotation of this arrow M to be the same as the direction of rotation N during winding, as shown in FIG.

Around the same time as the fully wound bobbin 5b is lowered, the empty bobbin 5a starts winding, and the filament 3 is cut near the presser plate 9 in the rotation direction M.

By matching N, the ends of the filament 3 wound around the fully wound bobbin 5b will never unravel or become tangled after cutting.

If the rotating transfer plate 11 further rotates from the virtual line in FIG. 4 to the state shown by the solid line (discharge position ■), the fully wound bobbin 5b will be
It is sent out while rolling through the discharge path 12.

By the time the winding on the upper bobbin 5 in FIG. 4 is completed, the rotary transfer plate 11 is restored as shown in FIG. It is transferred from the support base 2 to the rotary transfer plate 11 by its own weight. The limit switch 28 is activated immediately to detect this transfer. Accordingly, the motor 17 is activated to rotate the rotary transfer plate 11 from the position shown in FIG. 5 to the position shown in FIG.

By repeating each of the above operations in sequence, automatic supply and discharge is performed continuously.

〔Effect of the invention〕

The present invention achieves the following significant effects with the above-described configuration.

(2) Although there are few moving parts and the structure is simple, it is possible to reliably lower the fully wound bobbin 5b to the discharge path 12 below and send it out. Therefore, the incidence of failure is also significantly reduced.

■ The collar 6.6 of the fully wound bobbin 5b is the arc-shaped transfer path 21.
Since the filament 3 rolls against the friction portion 23 of the filament 3, by making the rolling direction coincide with the winding direction, the ends of the filament 3 after being wound will not unravel or become tangled.

■ Smooth operation allows for highly efficient work.

(2) Since the empty bobbin 5a supplied from the bobbin supply path 1 is stopped at a predetermined winding position A by the rotating transfer plate 11 which also serves as a stopper, the structure can be further simplified.
