Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to noise prevention technology in bookbinding equipment, and in particular to a milling and gully cutter feeding device for Mm and i8 machines that reduce the volume of the sound source generated. It is.

[Conventional technology]

The perfect binding machine conventionally used for perfect binding of books is equipped with a milling cutter for the purpose of cutting off the stomach part of the contents of the collated books over a width of about 3 meters, and the cut edge A gully cutter is installed for the purpose of cutting a notch for adhesive infiltration. In this type of perfect binding machine, the contents of the collated books are transferred to the milling cutter and gully cutter while being clamped from both sides with vise-type clamps, and the contents are transferred between the guide plates configured in a double-sided position. At the same time, cutting is performed between the guide plates while passing between the guide plates.

[Problem to be solved by the invention]

However, in the above conventional configuration, in order to allow the contents of the book held by the clamp to pass smoothly through the guide plate, the width between the guide rails is adjusted to be slightly wider than the actual thickness of the contents of the book. .

In other words, in perfect binding, the contents of a single set of books form a folded bag portion until the circumference is cut with a cutter including a milling cutter, and the thickness of the folded portion is different from that of the folded portion. The gap between the guide plates is widened to allow the core to pass through. Therefore.

With some milling cutters of this type, there is no pressure from a guide plate, and each leaf cut by the cutter generates vibrations and hits the adjacent paper, creating a source of tremendous noise and becoming a source of noise pollution in the bookbinding process. was.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a device that suppresses noise, particularly in the milling and gully cutter feeding devices of bookbinding machines and perfect binding machines. The purpose is to provide a compact structure.

[Means to solve the problem]

The milling and gully cutter supply device in the perfect binding machine according to the present invention is pivotally installed at a predetermined process position of the perfect binding machine,
A pair of guide roller support plates are pivotally installed so as to be openable and closable near one side of a disc-shaped milling or/and gullet cutter that is rotatably driven by a drive source such as a motor, and bearings are installed at opposing positions of both guide plates. A plurality of pairs of roller guides are constructed by rotatably mounting rollers, and a roller vise is constructed in which at least one of the guide roller supporting pugjets is elastically biased in the direction of approaching the collected books. The gist of the device is that a vise-type clamp for holding and transferring the contents is configured to move above between the opposing guide roller support plates.

Further, it is desirable that at least one pair of the opposing bearing rollers be located at the cutter blade position of the milling or/and gully cutter.

[Effect]

That is, in the above configuration, the contents of the collated books, which are clamped in a vise-type clamp and supplied to the milling and gully cutter, are clamped between the bearing rollers between the guide roller support plates of the roller vise, and then passed through the cutter blade. cut by. Therefore, the pressing force of the bearing roller is set to be greater than the cutting pressure of the cutter blade, and the adjacent sheets are clamped so that they do not flap during cutting, and the clamping position is set as close to the cutter blade as possible. With this configuration, it is possible to reduce the vibrating part of the main sound source that accompanies cutting, and thereby reduce the volume of sound emitted from the sound source.
