DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth roll changing device for a loom.

[0002]

2. Description of the Related Art A conventional cloth winding roll changing device for a loom is disclosed, for example, in JP-A-5-25742.

In this apparatus, a cloth winding roll is rotationally driven by a winding mechanism of a loom to perform winding of a woven fabric, and an empty cloth roll is previously stored in an empty roll stock mechanism (roll stocker) above a winding position. (Hereinafter, referred to as an empty roll). Then, when the cloth winding roll at the winding position reaches a predetermined cloth winding amount, the full winding cloth roll (hereinafter referred to as a full winding roll) is kept in a woven cloth state and a temporary placement position (unloading position) in front of the loom. After that, the empty roll is dropped from the empty roll stock section to the winding drive section, and the winding mechanism is used between the full roll discharged to the front of the loom and the empty roll mounted at the winding position. The woven fabric is cut, and the cut end of the woven fabric is wound around an empty roll. Then, the grooved roll at the carry-out position is carried out by the carrier.

Here, the payout means rotates a rail-shaped bracket piece (hereinafter referred to as a rail) which always extends in a vertical direction, and protrudes and extends it with a gradient in a horizontal direction. The full roll rolls up due to the gradient and moves to the carry-out position by its own weight.

[0005]

In the above-described cloth winding roll changing device for a loom, the full winding roll can be rolled on the rail to move it to a predetermined carry-out position without fail. When the full roll is rolled to the unloading position, the woven fabric length to be rewound for one rotation of the roll is longer because the outer peripheral length of the full roll is much longer than the roll circumference when rolling. In addition, the woven fabric may be unwound in large quantities, sag, the woven fabric may come into contact with the floor surface, become dirty, or be entangled with other equipment on the loom. There have been inconveniences such as generation of wrinkles due to slack when wound around a roll.

In order to avoid the above-mentioned inconvenience due to the rolling of the full roll, both ends of the full roll are supported by a pair of support arms, and the support arm is swung about its base, thereby providing a full roll. Attempts have been made to move the roll to an unloading position. Although this method solves the above disadvantages,
To swing the support arm supporting a very heavy full roll requires a considerably large driving force,
There is a possibility that the size of the apparatus will increase and the cost will increase.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cloth winding roll changing device for a loom which prevents the inconvenience of soiling the cloth and generating wrinkles during winding without increasing the size of the loom. To provide.

[0008]

In order to achieve the above object, the present invention releases a full roll from a state where it is held at a winding position of a loom and moves the full roll to a roll unloading position in front of the loom by a roll moving mechanism. Then, an empty roll is supplied to the winding position by an empty roll supply mechanism, and a woven fabric connected to the full roll is cut between the empty roll and the full roll by a winding mechanism to form an empty cloth roll. A roll moving mechanism, wherein the roll moving mechanism supports a full wound cloth roll released from a winding position and has a slide member capable of moving back and forth in the front-rear direction of the loom. Means and a sliding member of the roll supporting means are guided downwardly toward the unloading position, and the fully wound cloth roll supported by the roll supporting means is integrated with the sliding member to reduce the gravity of the fully wound cloth roll. Ri is characterized in that a slide guide means for moving the unloading position.

[0009]

According to the present invention, the full roll and the slide member supporting the full roll are moved together and transferred to the discharge position while supporting the full roll, so that the weaving is performed by rolling to the discharge position. It is possible to eliminate the inconvenience that the cloth is unwound in large quantities and becomes dirty, and that wrinkles are generated at the time of winding after cutting.

In addition, the full roll is supported by a slide member that can move forward and backward, and the slide member is guided downhill toward the carry-out position so as to move using the gravity of the full roll. Therefore, a large driving force is not required, and the loom can be prevented from being enlarged.

The main bracket 111 is mounted on the inner side surface of the side frame 1 and provides a wide mounting surface 113 which is separated from and parallel to the inner side surface. The upper end surface is formed on a roll rolling surface 115 provided with a guide portion 114. In addition, two roller bodies 11
Reference numerals 2a and 2b denote roller pins 116a and 116b mounted on the main bracket 111 and rollers 117a and 117b rotatably fitted thereto. The two roller bodies 112a and 112b are mounted lower than the roller 112a on the take-up position 6 and the roller 112b on the carry-out position 7 side. This is for guiding the member of the roll support means 140 described later to the carry-out position 7 on a downward slope.

In this embodiment, the roll transfer means 120 is provided as means for releasing the full roll 3a from the winding position 6 and supporting the roll 3a on the roll support means 140. The roll transfer means 120 is provided with a positioning stopper. 121 is provided. This positioning stopper 121 is an L which is rotatably attached to the main bracket 111 by a pin 122.
