Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding tape feeding device, and more particularly to a binding device for binding an image-formed sheet to a book, and more specifically, cutting a reel-shaped binding tape and then conveying it to a heater. Tape feeding device.

[0002]

2. Description of the Related Art Conventionally, an on-line device is used in which a plurality of devices for performing a job are connected when a plurality of sheets on which images are formed are glued and bound.

In the above-described on-line device, the tape supplied from the reel is side-guided by a tensioner with a flange to a cutter arranged immediately before a heater for heating and conveyed by a pair of rollers. At that time, since the tape is in a continuous state from the reel, it is transported at a low speed in consideration of the inertial force due to the rotation of the reel.

At the cutter portion, the tape is cut into a sheet having a required length.

[0005]

However, in the conventional tape feeding device, since the cutter portion is disposed immediately before the heater, the tape must be cut and pushed within the time for binding one bundle of sheets. I have to. Therefore, when the productivity of the image forming apparatus main body is increased as compared with the conventional one, or when a small number of bind bundles are required, the productivity of the image forming apparatus main body cannot be followed.

Further, in the method of positioning the cut tape on the heater, the pressing speed cannot be increased because the pressing member serves to convey and position the tape in the conventional method.

Further, in the conventional method, since the side portion of the tape is biased by the elastic member at the time of positioning, it is not possible to cope with variations in the material of the tape such as making the base paper of the tape thin and soft.

The present invention solves the above problems, enables continuous supply of tapes, and speeds up the tape transport, so that, for example, the bookbinding apparatus has high productivity and can cope with the image forming speed of the image forming apparatus. For the purpose of providing.

[0009]

In order to achieve the above object, the present invention has a binding tape which has an abutting means and a pushing means which are movable in the transport direction of the bind tape and which can approach and retract to the tape heating means. The positioning means and the auxiliary feeding means for the bind tape located at the end of the bind tape transport path on the upstream side of the pushing means.

Further, the binding tape is provided with a side regulating member on the heating means whose inlet side has a taper shape and a binding tape conveying means, and the auxiliary feeding means has a weaker gripping force for the bind tape than the conveying means. And

Further, the length of the conveying path from the bind tape cutting means to the inlet of the heating means is longer than that of the cut bind tape, and the bind tape conveying means downstream of the bind tape cutting means has the first speed and the second speed. It is characterized in that dual speed control is possible.

[0012]

According to the above construction, the tape fed from the tape reel and cut into the required length is conveyed from the cutter to the heater entrance at a speed higher than that of the continuous tape connected to the tape reel.

The tape is temporarily stopped before the heater and waits until the tape conveyed to the heater one cycle before is bound to the sheet bundle and conveyed.

When the heater is ready to be received, the tape is conveyed to the heater. At that time, the tape is regulated by the side guides on the side portions, so that the tape is easily inserted into the tape guide of the heater. Further, the abutting member and the pushing member that are normally retracted from the heater approach the heater, the abutting member is fixed at a position corresponding to the tape length (sheet size to bind), and the pushing member is located at the rear end of the tape. It is arranged on the upstream side and moves while pushing the rear end of the tape until the front end of the tape hits the abutting member. When the tape is positioned, the abutting member and the pushing member retract from the heater again.
