Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to, for example, coiled iron,
The present invention relates to a strip guiding device for automatically guiding and feeding a strip made of a material such as stainless steel or aluminum to a subsequent device.

BACKGROUND ART Conventionally, coiled strips made of materials such as iron, stainless steel, or aluminum have been tightened using cable ties to prevent them from exploding due to their elastic resilience. . For example, when pressing such a strip, the coiled strip is attached to an uncoiler and the binding band is cut off, and a straightening device called a leveler is used to remove the distortion caused by bending in the winding direction. After being straightened into a flat shape, it is pressed into, for example, an automobile body using a press machine.

Such prior art is not configured to automatically guide the end of the strip taken out from the uncoiler and feed it to the leveler, so the end of the strip may not be guided in a direction other than the predetermined guiding direction. If it deviates, the end of the strip must be guided manually by the operator, and the end of the strip cannot be brought to the feeding position accurately and reliably. Moreover, it is necessary to frequently drive and stop the uncoiler in order to guide the end of the strip to the supply position of a straightening device such as a leveler, which is not only inefficient but also dangerous.

Problems to be Solved by the Invention An object of the present invention is to automatically guide the end of a strip to accurately and reliably bring it to a supply position, and to improve workability. It is an object of the present invention to provide a guiding device for a band-shaped body.

Means for Solving the Problems The present invention provides a belt-shaped body guiding device that guides an end of a supplied belt-shaped body toward the downstream side in the guiding direction, the belt-shaped body being angularly displaced about an axis intersecting the feeding direction, a swinging member formed with a first guide path into which the strip is inserted; a pair of nipping rollers that are interposed in the first guide path and at least one of which is rotatable only in the guide direction; An engaging member is provided on the downstream side of the rocking member so as to be angularly displaceable, and is formed with an engaging portion with which the end of the strip is engaged; a freely disposed guide member, and a release means for releasing the engaging state of the engaging portion from the end portion of the band-like body when the swinging member reaches a predetermined operating position from the starting position; , such a guide member has an overlapping part that overlaps the engaging member along the guiding direction when the swinging member is in the operating position, and a second guide path continuous to the overlapping part is formed. 1 is a guide device for a band-shaped body, characterized in that it includes:

The present invention also provides a belt-shaped pair of rollers, characterized in that the axis of one roller is disposed above the axis of the other roller and downstream in the guiding direction, and is displaced with respect to the axis of the other roller. It is a body guiding device.

Effect According to the present invention, when the end of the strip is supplied to the first guide path, the end of the strip is engaged with the engaging portion of the engaging member, and the end of the strip is engaged with the engaging portion of the engaging member, and It is held between the holding rollers. This pinching roller is
Since at least one of them is rotatable only in the guiding direction, it is possible to prevent the sandwiched strip from moving in a direction opposite to the guiding direction. After that, the swinging member starts an angular displacement movement from the starting position to the operating position, and when the swinging member reaches the operating position,
The engaging member overlaps the guide member at an overlapping portion, and the engaging state between the end portion of the band-shaped body and the engaging portion is released by the releasing means.

In this state, if the uncoiler is driven in the guiding direction, the end of the strip will be guided by the guide member along the second guide path, and the strip will be guided downstream in the guiding direction to be followed by the following. automatically supplied to the equipment that

Further, according to the present invention, the axis of one of the pinching rollers is disposed above the axis of the other roller and on the downstream side in the guiding direction, so that the pinched belt-shaped body can be placed on the other side disposed below.
