JPH07195864A - Device for book binding machine for dividing content at its center - Google Patents

Abstract

PURPOSE: To divide interior of book in a stable manner by a device wherein a book or the interior thereof is pressed against a dividing member to divide the interior at the central portion thereof, a bluntly formed blade is provided on the forward end of a dividing member, while a nozzle is provided on the front stage of the blade to blow off air against an end of the interior. CONSTITUTION: In a bookbinding machine, particularly a device for a casing-in machine, a book or the interior 1 thereof being carried by a conveying device 7 is pressed against a dividing member 2 to divide the interior at its central portion. The interior 1 is conveyed by being guided by a guide roller 8 and fed onto a transfer board 6. A dividing tip end 3 having a bluntly formed blade 4 is attached to the member 2. At the front stage of the member 2, a nozzle 5 is disposed to blow off compressed air against an end of the interior 1. Thus, even if the interior comprises thick sheets, the interior can be divided at the central portion thereof in a stable manner, without damage thereto.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for a bookbinding machine, in particular, a wrapping machine, which presses contents or books carried by a carrier device against a dividing member to divide the book at the center.

[0002]

2. Description of the Related Art As is well known, in order to wrap a cover with a wrapping machine, the contents of a book are conveyed by a conveying device with a front edge placed on a passage surface, pressed against a dividing member, and then transported by the wrapping machine. Received on the board and straddle this. The desired central division of the contents is achieved by a dividing member having a pointed protruding dividing tip at the front end.

The conventional dividing member is only applied conditionally for the purpose of dividing the contents, such as a plate for children's books and a mount for a photo album. When the contents of cardboard, laminated paper or similar materials are divided at the center, the edge of the cardboard sheet or mount may tear if it hits the tip of the division, or the paste may be damaged if laminated. There are many dangers.

Furthermore, when the leading end of the dividing member hits a cardboard sheet or a laminated sheet, a functional failure may occur in the progress and thus the operation may be interrupted.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is an apparatus for a bookbinding machine, particularly a wrapping machine, for pressing a content or a book carried by a conveying device against a dividing member to divide the book at the center. Therefore, it is an object of the present invention to provide a device that guarantees functionally stable division of the contents of thick single-leaf without damage.

[0006]

In order to achieve the above object, in the device of the present invention, the dividing member has a dividing tip portion having a bluntly formed blade portion. Further, there is provided a nozzle that acts on the small edge of the contents and blows out compressed air. Preferred configurations of the invention are described in the dependent claims.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings.

The contents 1 made of cardboard sheets to be sent to the dividing member 2 are conveyed with the front edge facing down.
Is periodically conveyed by the arrow direction, is supported by the guide roller 8 on the side, and is pressed against the divided tip portion 3 of the divided member 2. At this time, the contents are divided at the center, further carried by the carrier device 7, and finally received by the carrier plate 6 of the case machine and straddle it.

According to the present invention, from the viewpoint that the contents 1 made of thick single sheets are functionally stably divided without damage, the division tip portion 3 is provided with the rounded blade portion 4, and the division tip portion 3 has A nozzle 5 that blows out compressed air is provided in the front stage, and this nozzle acts on the front edge of the contents 1 to open the sheet.

The compressed air nozzle 5 is adjusted in position in the vertical direction along with the split tip 3 and in the arrow direction along the conveying device 7 by a common device (not shown) in consideration of various contents formats. it can.

From the viewpoint of functionally stably dividing the contents 1 without damage, the contents 1 are divided with respect to the conveying device 7 so that the contents 1 hit the dividing tip 3 at a deceleration stage of the conveying cycle, that is, at a very low speed. It has been found to be particularly convenient to position the tip 3.

Instead of the compressed air nozzle 5 provided independently, it is possible to provide a hole for blowing out compressed air in the divided tip portion 3.

[0013]

As described above, according to the present invention, a dividing member for dividing the contents conveyed by the conveying device at the center is provided between the conveying device for the contents of the book and the following wrapping machine. By installing a nozzle that blows compressed air to the front edge of the contents to help divide the contents, the function is stable and smooth without damaging the contents even if the contents are thick sheets. It is possible to provide a device for a wrapping machine, which guarantees a central split opening.
