Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for producing a bound form, in which a continuous form in which a predetermined number of unit forms are continuous and a continuous form to be collated are collated. The present invention relates to a form sheet cutting apparatus for cutting a sheet for each unit form and a binding form.

[0002]

2. Description of the Related Art In recent years, when a binding form is produced,
A pressure-sensitive adhesive was previously applied to continuous paper printed by a printer, and collated when necessary.However, there is a case where blocking due to the pressure-sensitive adhesive may occur during storage before collation. In some cases, a pressure-sensitive adhesive is applied at the time of collation. The bonding at the time of collation is performed in an undried state, and it is desired to improve the yield and the like when cutting continuous paper into bound sheets.

Conventionally, a form collating apparatus is prepared in such a manner that continuous paper in which unit forms to be bound are continuous is printed by a printer in advance in accordance with the number of sheets to be bound. Normally, the adhesive is not applied to the form on the first page and the adhesive is applied to the form from the second page. The same process is performed at each stage according to the number of sheets, and collation is performed. Positioning in this case is performed by detecting the leading end of each continuous sheet and aligning the leading end. Then, after the bonding between the unit forms of each continuous paper is performed, unnecessary portions are cut and separated by a cutting device called a detacher, and cut for each binding form.

[0006] FIG. 6 is an explanatory view of a conventional form sheet cutting apparatus and continuous paper carry-in. FIG. 6A shows a collating system 101 for producing a binding form, which includes a collating device 102 and a cutting device 103. The collating apparatus 102 prepares continuous sheets of a number corresponding to the number of sheets of a binding form, and binds each continuous form to each unit form for the continuous unit forms constituting the continuous form. Then, the form sheet 104 is produced and discharged to the cutting device 103.

[0005] The collating device 102 and the cutting device 103 are arranged at a predetermined interval.
Is sent to the cutting device 103 in a suspended state where it is naturally suspended.
The cutting device 103 is provided with a receiving portion 105 at a portion where the form sheet 104 is carried in. The receiving portion 105 is formed partially in an arc shape and guides the form sheet 104 into the cutting device 103. The continuous paper is conveyed by engaging holes in a marginal portion provided in the continuous paper with pins of a tractor provided in the collating device 102 and the cutting device 103.

[0006]

However, FIG.
As shown in (B), when receiving the continuous paper 104 that has been naturally hung from the loading unit 105 of the cutting device 103, the frictional force generated on the surface of the receiving unit 105 due to the weight of the continuous paper 104 in the gravitational direction and the transport force. Are concentrated, and a force is applied to a form collated by the frictional force in a direction opposite to the conveying direction, so that the form is easily bent and shifted. That is, since the adhesive for collating is undried immediately after application, it is in an incompletely adhered state, and the thickness of the form to be collated may be different.
There is a problem that the adhesion position shifts due to the frictional force with the adhesive layer 05, and the yield is reduced due to tearing or peeling. Further, there is a problem that the position of the hole of the marginal portion is displaced between the continuous papers, so that the paper is easily dropped from the transport tractor in the cutting device 103, and the efficiency is reduced due to the stoppage of the device.

In view of the above, the present invention has been made in view of the above problems, and reduces the local frictional force applied to a form sheet.
It is an object of the present invention to provide a form sheet cutting device and a binding form that improve yield and efficiency.

[0008]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, there is provided a continuous sheet in which unit forms are continuously separated so that a guide portion for transport is provided at an end portion. Is prepared in accordance with the number of sheets to be bound, and a form sheet that is applied with an adhesive to each of the unit forms and that is cut and separated for each bound unit form while removing the guide portion. In the cutting apparatus, when receiving the form sheet, an introduction unit for guiding the form sheet into contact with the form sheet for a predetermined length is provided.

In the invention according to claim 2, the introduction means is provided so as to extend to a receiving portion provided at a portion where the form sheet is carried in. According to a third aspect of the present invention, the form sheet cutting apparatus according to the first or second aspect forms a binding form produced by cutting the form sheet for each bound unit form.

As described above, the introduction means which comes into contact with the form sheet for a predetermined length is guided at the portion for receiving the conveyed form sheet. As a result, the frictional force with respect to the form sheet is not dispersed and concentrated locally, and the bending of each continuous form is reduced, and the displacement, tearing, and peeling of the bonding position are prevented, so that the binding form production It is possible to improve the yield and the production efficiency.
