shearing machine

Abstract

The present invention provides a shearing machine capable of neatly cutting the ends of a bound matter without skewing the ends of the bound matter or damaging the cover of the bound matter. With respect to the end (1a) of the bound object (1) placed on the workbench (10), set a small space (X) in the moving direction (56a) and extend in parallel to each other first and second. Cutting positions (100, 101), the first cutting position (100) is arranged on the outside of the binding object (1) than the second cutting position (101), and the control unit (7) controls the driving of the shearing knife as follows: The actions of the mechanism (21) and the moving mechanism (56): after the end portion (1a) of the binding object (1) is cut at the first cutting position (100), the shearing knife (20) or the workbench ( 10) Moving along the moving direction (56a) with a small interval (X), and cutting the end (1a) of the bound object (1) at the second cutting position (101).

Description

Technical field [0001] The present invention relates to a shearing machine used in a binding process to cut the top and bottom and cuts of a bound material in order to complete the binding. Background technique [0002] As a conventional shearing machine, there is a shearing machine described in Patent Document 1, for example. The shearing machine is provided with a single shearing blade that reciprocates between a non-shearing position and a shearing position in the vertical direction, and a worktable for placing and positioning the bound material. In this shearing machine, the operator puts the binding object on the worktable and positions it, and moves the shearing knife from the upper non-cutting position to the lower cutting position to cut the ends of the binding object. cut. In addition, the operator rotates the bound material to the top cutting position, bottom cutting position, and notch cutting position, and reciprocating the shearing blade between each position, so a...

Problems solved by technology

Therefore, if Figure 7 As shown, in the case where the end portion 1a of the bound matter 1 to be cut is long, if the end portion 1a of the bound matter 1 is cut only once with the shear blade 20, the end portion 1a of the bound matter 1 may sometimes be cut. Part 1a is skewed or cover 1f of bound product 1 is damaged

Additionally, if Figure 8 As shown, in the case of cutting the folded portion 1g of the bookbinding that folds each page of the bound matter 1 in half, if the end portion 1a of the bound matter 1 is cut only once by the shear blade 20, sometimes The end 1a of the bound item 1 cannot be trimmed neatly
