Description

[Detailed Description of the Invention] The present invention relates to a wrap supply device for a combing machine.

The weight of the wrap used in the combing machine is 40 to 50. The weight of the wrap is rolled up to around 7,000 yen.The wrap sent from the previous process is manually placed on the wrap receiver installed on the top of the combing machine.
When the lap being combed runs out, the bobbin is removed from the wrap roller, the spare wrap at the standby position is fed onto the wrap roller, the trailing end and the starting end of the wrap are joined together, and the combing operation is continued.

As previously shown in Japanese Utility Model Publication No. 48-39060, a wrap supply device for supplying the preliminary wrap to the wrap roller is provided at the rear part of the combing machine stand opposite to the operation side, and slightly above the wrap roller with a distance therebetween. A lap plate is installed diagonally downward in the front, and a stop lever is provided between the lap plate and the lap roller, which can be raised and lowered by a handle lever, and a shaft is placed horizontally on the stop lever. There was one that was constructed so that it always stood up using a spring.

However, with the above-mentioned wrap supply device, the handle lever must be pushed to directly press the shaft of the stop lever onto the preliminary wrap, while retracting the wrap slightly upward diagonally before guiding it onto the feed roller. There was a defect in that the force required to operate the lever was extremely large, causing damage to the surface layer of the wrap.

In view of the above-mentioned defects, the purpose of the present invention is to supply the spare lap to the lap roller without causing damage to the surface surface, and in this case, it is possible to easily operate the handle lever, and the spare lap is transferred from the cart to the lap plate. To provide a wrap supply device for a combing machine, which can reliably prevent a reserve wrap from falling forward when rolled and can stably wait the reserve wrap on a lap plate.

Hereinafter, an embodiment embodying the present invention will be explained with reference to the drawings. In the drawings, 1 is a machine base, and 2 and 3 are two places in front and behind a stand 40 installed on the machine base 1, and a constant drive device (not shown) A pair of wrap rollers that are actively rotated counterclockwise at a high speed, and a wrap R supported on both wrap rollers 2 and 3 is passed through a wrap guide roller 5 (not shown) disposed in front of the wrap roller 2. It is designed to be supplied to the nipper.

A combing cylinder 6 is supported under the guide roller 5 so as to be actively rotatable, and a combing roller 7 receives and guides the fleece combed by the cylinder 6 forward.

Reference numeral 8 denotes a bracket 9 fixed to the rear upper side of the stand 4.
This is a lap plate that supports a preliminary wrap Ra that is tiltably supported in the vertical direction with respect to a support shaft 10 horizontally suspended at the rear end, and has a wall surface 8a formed by bending its front end at right angles downward. A pair of U-shaped tilting position regulating members 11 are fixed to the inside as shown in FIG. I'm letting you do it.

When the upper regulating piece 11a of the position regulating member 11 abuts on the spindle 12, the lap plate 8 is held in the forward downward inclined position, and when the lower regulating piece 11b abuts on the spindle 12, The lap plate 8 is held in a front upward inclined position.

Note that the upper and lower regulating pieces 11a. A cushion member 13 made of rubber, resin, etc. is adhered to 11b.

Reference numeral 14 indicates a member for preventing the preliminary wrap Ra from falling off, which is fitted and secured to the wall surface 8b formed by bending the rear end of the wrap plate 8 upward at right angles, and reference numeral 15 indicates a member on both sides of the wrap plate 8, as shown in FIG. A pair of guide bars guide the preliminary wrap Ra attached parallel to each other in the front-rear direction on the upper surface, and a handle lever 16 having a U-shape in plan is connected to the front end portions of the guide bars.

11 is a cylindrical portion 17 formed at the base end as shown in FIG.
A is loosely fitted onto the spindle 12 and has an arcuate side surface whose upper part protrudes upward from an opening 8c formed transparently in the lap plate 8. This is to prevent the wrap Ra from rolling forward and falling off when being transferred.

A pair of stop rings 18 and 19 are fitted onto the support shaft 12 and fixed by set bolts to prevent the stopper 17 from moving in the axial direction.

20 is a coil spring whose one end is inserted and locked into the stop ring 19, whose middle part is wound around the support shaft 12, and whose other end is in contact with the lower surface of the stopper 17, and which always urges the stopper 17 upward. are doing.

An operating member 21 is fixed to the lower surface of the lap plate 8 and has its lower end in contact with the stopper 17. When the lap plate 8 is rotated counterclockwise, the stopper 17 is pushed downward and the lap plate is rotated. 8 and evacuate downward.

Next, the operation of the wrap supply device configured as described above will be explained.

Now, in FIG. 1, the wrap R is placed on the wrap rollers 2 and 3 and the combing work is performed, and the preliminary wrap Ra is placed on the lap plate 8, and the lap plate 8 is arranged in a diagonal shape with the front upward. is held in

When the wrap R on the wrap rollers 2 and 3 runs out, the operator removes the bobbin B and pushes the handle lever 16 downward.

As a result, the lap plate 8 is moved to the first position around the support shaft 10.
The stopper 17 is rotated counterclockwise in the figure, and the stopper 17 is rotated clockwise in the figure by the actuating member 21 about the support shaft 12 against the elasticity of the coil spring 20.

Then, the upper regulating piece 11a of the position regulating member 11
2, the stopper 17 is retracted below the lap plate 8 by the actuating member 21 as shown in FIG. It rolls on the top and is supplied onto the wrap rollers 2 and 3.

Therefore, when the preliminary lap Ra rolls on the lap plate 8, it can roll smoothly without coming into contact with the stopper 17.

After that, when the operator releases the handle lever 16, the lap plate 8 becomes slightly heavier at the rear of the support shaft 10.
In addition, since the actuating member 21 is pressed upward by the coil spring 20, the lap plate 8 moves to the fourth position around the support shaft 10.
It is rotated clockwise in the figure and automatically returned to the forward upward slope shown in FIG. 1, and the stopper 17 is projected to the upper surface of the lap plate 8.

In this state, at an appropriate time, the worker removes the preliminary lap R from the trolley.
A is replenished onto the lap plate 8, but at this time, the spare lap Ra is rolled from the cart and placed on the lap plate 8, so its inertia tends to cause it to fall forward over the support shaft 10. It is rebounded by the stopper 17 and retreated to the drop-off prevention member 14 and held there, maintaining the wrap plate 8 in an upwardly inclined state and securing a standby position for the preliminary wrap.

Now, in the embodiment of the present invention, the lap plate 8 is supported so as to be tiltable obliquely upward or downward about the support shaft 10, and as the lap plate 8 is tilted, it automatically moves in and out of the upper surface of the lap plate 8. Since the stopper 17 is attached to the machine base 1, by pushing the handle lever 16 downward using the support shaft 10 as a fulcrum, it is possible to easily move the heavy spare wrap Ra packaged in a large package without climbing over any obstacles. In addition to being able to supply the lap rollers 2 and 3, the stopper 17 is in a protruding state when replenishing the spare lap Ra from the cart onto the lap plate 8.
It is possible to reliably prevent the preliminary wrap Ra from rolling forward and falling off from the wrap plate 8.

Therefore, the operator can work easily without having to pay close attention.

As described in detail above, the present invention includes a fall-off prevention member 14 for the preliminary wrap Ra at the rear end of the combing machine stand 1 on the rear side opposite to the operation side and located slightly above the wrap rollers 2 and 3. The wrap plate 8 is provided with a nozzle lever 16 at its front end, and the middle part of the lap plate 8 is supported so as to be tiltable in the vertical direction. A position regulating means is provided to lock and hold the front downward inclined position, and the machine base 1 is further provided with a stopper 17 which projects upwardly from the lap plate 8 by means of a biasing member to prevent the spare lap Ra from falling forward. is rotatably supported, and an operating member 21 is provided on the lower surface of the lap plate 8 for rotating the stopper 17 downward and retracting it from the lap plate 8 when the lap plate 8 is tilted to the forward downward position. The spare wrap can be easily supplied to the wrap roller with a very small operating force, and the spare wrap can be prevented from falling forward when being supplied from the truck to the lap plate.
