Description

Lifting Structure of Length Measuring Roller of Automatic Cutting Machine

This paper relates to the improvement of the structure in which the length measuring roller moves up and down, especially in the automatic cutting machine which cuts the fabric discharged by the killing machine (QUILTING M / C) by a certain length. It is very smooth and accurate.

Looking at the configuration and operation of the general automatic cutting machine through Figure 1,

The killing fabric 20 enters from the rear end, passes through two guide rollers 21 and 21 ', and passes through a length measuring roller 7 configured to be freely lifted therebetween, and in front of the automatic cutting machine 1. By passing through the take-out rollers 22, 22 'and the side end cutter 23, the edge of the fabric 20 is cut, and again passes through the take-out rollers 24, 24' and the length cutting cutter 25. While cutting to the required length.

Looking at the process of measuring the cutting length of the fabric in detail the length measuring roller (7), the first take-out rollers 22, 22 ', 24, 24' is only holding the fabric 20 in the stopped state The length measuring roller 7 starts working in the state of lifting up to the upper limit. When the fabric 20 starts to enter little by little, the length measuring roller 7 is placed on the fabric so that the fabric enters by its own weight. As much as possible to descend.

When the length measuring roller (7) continues to descend and the fabric enters the length necessary to cut once, and the length measuring roller (7) descends to a predetermined position, the limit switch detects this and takes out the rollers (22, 22 ') (24). ) And 24 'to pull the fabric 20 forward, so the length measuring roller 7 enters the upper limit as the first time, and then the length cutting cutter 25 acts to cut the fabric.

Looking at the conventional lifting structure of this length measuring roller through Figure 2,

The pinion gear 30 and the guide roller 31 are formed at both ends of the length measuring roller 7a, and the rack gear 32 and the guide roller engaged with the pinion gear 30 in the adjacent frame 40 ( 31) are elevated When the length measuring roller 7a is lowered by entering the fabric or ascended for cutting operation, the pinion gear 30 is lifted by the rack gear 32.

However, the conventional lifting structure has a disadvantage in that it takes a lot of cost to manufacture the rack gear 32 and the pinion gear 30, and the length measuring roller because the rack gear 32 and the pinion gear 30 are used. When the gear (7a) is lowered and lowered, the gears and teeth are engaged with each other, and the vibration and noise occur as if 'tuck tuk' is caught.The rack gear (32) and the pinion gear (30) no matter how precisely. Even if it is made, even if the lifting and lowering was not able to maintain the complete level, which one side is slightly sag, there was also a problem that the cutting is not made correctly.

This proposal drawn out by the above problems is to improve the structure of lifting the length measuring roller of the automatic cutting machine to the structure using the wire rope, so that the structure is simple and low cost, and the lifting operation is very smooth and accurate. I did it.

* Explanation of symbols for the main parts of the drawings

1: Automatic cutting machine 2, 2 ': Frame

3, 3 ': fixture 4, 4': support tube

5, 5 ': lifting body 6: bearing block

7: Length measuring rollers 9, 9 ', 10, 10', 11, 11 ': Poufpoly

12, 12 ': wire stopper 13, 13': wire rope

This proposal attaches the fasteners (3) and (3 ') to the upper and lower portions of both side frames (2) and (2') and then fixes the support tubes (4) and (4 ') using the fixtures (3) and (3'). And the sliding body 5, 5 'is inserted into the outer surface of the support pipe 4, 4' to slide, and the bearing block 6 is fixed to both lifting bodies 5, 5 'to measure the length. Both ends of the roller 7 fix the bearing block 6 so that both ends of the length measuring roller 7 are supported by the bearing block 6.

At the top of both frames (2) and (2 ') and at the bottom of the lateral and lower fasteners (3') of the upper fasteners (3 '), respectively, paw polys (9) (9') (10) (10 ') (11) and (11 '), and wire fixing pieces (12) and (12') are projected on the upper and lower portions of both lifting bodies (5) and (5 '), respectively. ), One wire rope 13 secures one end to the upper wire fixing piece 12 of one lifting body 5, and then to the upper rope poly 10 and the frame 2 'on the opposite side. The inside of the support tube 4 'is also introduced through the fixed rope poly 9', and the end of the wire fixing piece is formed at the bottom of the elevating body 5 'while winding the rope poly 11' at the bottom half a turn. To 12 '.

The other rope 13 'is connected to the above-mentioned rope 13, which is fixed at one end to the upper wire fixing piece 12 of one lifting body 5', and then the upper rope poly 10 '. And it enters into the inside of the support tube 4 via the fixed rope poly 9 of the frame 2 on the opposite side, the end of which is the bottom of the elevating body 5 while winding the rope poly 11 at the bottom half. It is fixed to the wire fixing piece (12 ') formed in the.

Unexplained reference numeral 14 in the drawings is a limit switch for detecting the rising limit of the length measuring roller (7), 14 'is a limit switch for detecting the falling limit of the length measuring roller (7).

The operation of this paper in this configuration will be explained.

First, when the fabric 20 continues to enter little by little, the length measuring roller 7 descends, and then the lower limit switch 14 'is acted on, and the take-out rollers 22, 22' and 24 (in front of the automatic cutting machine 1) are operated. 24 ') is operated to pull the fabric 20 at high speed so that the length measuring roller 7 starts to rise.

As a result, the wire ropes 13 and 13 'on both sides move simultaneously. When the length measuring roller 7 is raised, the wire ropes 13 and 13' connected to the lower side of the two lifting bodies 5 and 5 'are pulled. As the length becomes longer and the other side is connected to the upper part of the elevating body (5) (5 '), the length is shortened while continuing to replenish the length as it is pulled.

When the length measuring roller 7 is raised to act the upper limit switch 14, the action of the draw rollers 22, 22 ', 24 and 24' is stopped and the length cutting cutter 25 acts to cut the fabric. After cutting, the length adjustment roller 7 is lowered little by little by the fabric 20 supplied from the kilting machine again. In this case, the wire ropes 13 and 13 'act as opposed to the above rise.

As described above, the present invention hangs two wire ropes 13 and 13 'at both ends of the length adjusting roller 7, and supports 4, 4' and several rope polys 9 and 9 '. (10) (10 ') (11) (11') Because the configuration is completed, not only the configuration is much simpler than the conventional lifting structure, but also the cost required for manufacturing is much reduced, so that it is possible to supply a low-cost automatic cutting machine. .

In addition, two wire ropes 13 and 13 ′ having the same length are fixed to both ends of the length adjusting roller 7 so as to act organically. Without this at all, it is possible to achieve a very smooth ascent action, and the effect is very excellent design.
