Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a holding device for holding the leading ends of a plurality of divided strip-shaped sheets obtained by dividing a raw strip-shaped sheet such as a metal foil, a plastic film, or paper by a slitter. The present invention also relates to a divided strip-shaped sheet guiding device for holding the leading end portions of a plurality of divided strip-shaped sheets with a holding device and guiding the divided strip-shaped sheets along a path of the divided strip-shaped sheets.

2. Description of the Related Art Conventionally, as a device for holding a leading end of a divided strip-shaped sheet, there is a type in which a divided strip-shaped sheet is sandwiched and held between a pair of beam members urged against each other by a spring. The pair of beam members of the holding device are opened by a cam mechanism at a receiving position of the divided band-shaped sheet against a spring, and closed away from the receiving position by the action of the spring. Then, in order to translate the plurality of divided strip-shaped sheets sent to the receiving position, their leading ends are sandwiched together (for example, see the specification and drawings attached to Japanese Patent Application No. 154256/1989).

(Problems to be Solved by the Invention) However, the above-mentioned type is not sufficient to reliably hold the leading end of each divided strip-shaped sheet. That is,
In the conventional holding device, the clamping force of a part of the divided band-shaped sheet sandwiched between the pair of beam members is reduced, and the divided band-shaped sheet having the reduced clamping force is sagged during the transfer, so that the sheet is not removed at the unloading position. There have been problems in that the subsequent processing is hindered, and that part or all of the divided strip-shaped sheet is detached from the beam member and cannot be guided.

Whatever the strip-shaped sheet, there is some thickness unevenness, and the flatness of the beam member also has a limit in processing accuracy. Since the divided strip-shaped sheet is originally small in thickness, a slight difference in the thickness or a partial small gap between the pair of beam members greatly affects the holding force of each divided strip-shaped sheet. Therefore, in order to reliably hold the leading end of the divided band-shaped sheet, it is necessary to increase the clamping force between the pair of beam members, and to do so, the spring force must be increased.

However, when the force of the spring is increased, it becomes difficult to open the space between the pair of beam members. And to open between the pair of beam members,
A force that overcomes the force of the spring is applied to one of the beam members by a cam mechanism, and it is necessary to securely support the other beam member so as not to move with the force, and a transfer mechanism that supports the other beam member The mechanical strength must be increased. Therefore, it is difficult to sufficiently increase the force of the spring.

Therefore, in the holding device of the above-mentioned type, a mechanism that supports the device is simple, and a device that can reliably hold the leading end of the divided strip-shaped sheet cannot be obtained.

Incidentally, it is conceivable to attach a drive mechanism such as a fluid pressure cylinder to the beam member in order to increase the holding force. However, in this case, there is a problem that the structure of the holding device becomes too large due to the driving mechanism, or a supply unit for supplying a fluid pressure or other power medium to the driving mechanism becomes too complicated. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a simple device for holding the leading end of a divided strip-shaped sheet that can reliably hold the divided strip-shaped sheet.

It is good to have.

(Operation) In the device for holding the leading end of the divided strip-shaped sheet of the present invention, the first
