Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a three-sided cutting machine, and more specifically, the invention relates to the improvement of a three-way cutting machine, and more specifically, the data input of the top, bottom, edge dimensions, and cutting margin of finished books and base books (materials to be cut). This invention relates to a three-sided cutting machine that can automatically feed and position a material to be cut (original book) to a predetermined position.

(Conventional technology) Conventional three-way cutting machines perform various positioning functions, such as adjusting the position of the top and bottom blades (span size), adjusting the feed amount in the top and bottom directions and in the edge direction, and adjusting the stopper presser in the top and bottom directions, depending on the size of the finished book. Adjustment operations are required, but in the past, this was often done manually and relied mainly on intuition.

(Problem to be solved by the invention) For this purpose, highly skilled and experienced engineers are needed.

In particular, when adjusting the feed in the edge direction and in the vertical direction, there are many elements of dimension adjustment based on intuition, making the adjustment work extremely difficult for inexperienced or clumsy workers. Met.

Furthermore, in the case of cutting with a three-sided cutting machine, the book (material to be cut) is cut in three directions at the same time, so if each of the above-mentioned adjustments is incorrect, all the books will be defective.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned conventional problems, and is constructed as follows.

That is, the three-sided cutting machine of the present invention has a span size adjustment mechanism for two vertical blades that are opened and closed by a left-right drive by a servo motor, and a vertical feed tool and a fore direction feed tool by a feed screw driven by a servo motor. a feed adjustment mechanism for moving the tool forward and backward in the vertical direction and edge direction of the object to be cut;
The same as above consists of a stopper adjustment mechanism that moves the stopper in the vertical direction forward and backward, and a data processing control unit equipped with a calculation unit that calculates the number of rotations of each motor and the rotation angle. The feature is that the material to be cut is automatically fed and positioned at a predetermined position by inputting data of the cutting margin.

Next, the three-sided cutting machine of the present invention will be described in detail with reference to the drawings in terms of embodiments.

〔Example〕

First of all, in Fig. 1, A is the span size adjustment mechanism for the top and bottom blades, and the two left and right top and bottom blades 1a and lb each have nuts 24a.
, 24b, left-hand thread 2a, right-hand thread 2 of left-right thread 2
b, respectively, and the span size can be changed appropriately by opening and closing displacements by driving the left and right heists 2 in forward and reverse directions by a servo motor 3. Next, in FIG. 1, B is a vertical direction feed adjustment mechanism, in which a vertical direction feed tool 14 for feeding the material to be cut (bookbinding) 4 on the machine base 5 in the vertical direction is connected to a feed screw 17 via a nut 15. The vertical feeding tool 14 is moved forward and backward as required by forward and reverse rotation of the feed screw 17 by a servo motor 16 screwed into the screw. In addition, in Fig. 2, C is the edge direction feed adjustment mechanism;
An edge direction feeding tool 19 for feeding the upper object to be cut (bookbinding) 4 in the edge direction is connected to the feed screw 22 via a nut 2o.
The feed screw 22 is screwed into the servo motor 21, and the feed screw 22 is driven in forward and reverse directions so that the feeder 19 moves forward and backward in the direction of the edge as appropriate. Note that 18 is a small knife. Furthermore, D is a stopper adjustment mechanism.

As shown in FIG. 1, a feed screw 7 integrated with the stopper 6 is supported by a support rod 8 via a nut 9.
Chain wheel 10 integrated with the chain wheel 11 of the upper servo motor 12
An open chain 13 is wound between the servo motor 1 and
The stopper 6 can be moved forward and backward in the vertical direction by the forward and reverse rotation drive of the stopper 2.

Further, FIG. 3 shows a block system diagram of a data processing control section including a calculation section for calculating the rotation speed and rotation angle of each motor.

The rotation angle (9 rotations) of each servo motor is managed by the calculation unit to determine the amount of movement of each feeding tool 14, 19, and the stopper 6.
It also controls the positions of the top and bottom blades 1a and lb.

That is, in this invention, the finished book top-bottom dimension a, the base book top-bottom dimension d, the finished book fore-edge dimension, the binding small-tooth dimension', and the top-bottom cutting allowance 12. By inputting the data of the edge cutting margin m, the object to be cut (bookbinding) 4 is automatically fed and positioned to a predetermined position, and three-way cutting is performed.

Note that the edge cutter 18 is in a fixed position, and the finished edge dimension of the finished book 23 is determined by the stop position of the edge direction feeding tool 19.

Further, the vertical stopper 6 is always positioned from the machine center M at a position equal to half of the finished vertical dimension a of the finished book 23 plus the vertical cutting margin Q.

Furthermore, the vertical direction feeding tool 14 is a vertical direction stopper 6.
The forward end position is set forward by the vertical dimension d of the bookbinding (material to be cut) 4, and the stroke position determined from this position is set as the backward end position, and reciprocating motion is performed between these positions.

(Effects of the Invention) The three-way cutting machine of the present invention has a calculation method that calculates the number of rotations and nine rotation angles of each motor of the top and bottom blade span size adjustment mechanism, the top and bottom direction and edge direction feed adjustment mechanisms, and the top and bottom direction stopper adjustment mechanism. It consists of a data processing control section with a section, and by inputting the data of the top, bottom, edge and edge dimensions of finished books and bound books, as well as the cutting margin, the material to be cut is automatically fed into a predetermined position and positioned. An outstanding product that allows you to perform various positioning adjustment operations such as position adjustment, vertical and fore direction feed amount adjustment, vertical stopper presser adjustment, etc. in a stable, automatic and positive manner without relying on intuition like conventional methods. effective.

In addition, since a feed screw drive mechanism using a servomotor is used to feed each feeding tool and stopper, it is possible to obtain characteristics such as accurate stillness and harmonious movement function, which significantly improves the functionality of this type of three-way cutting machine. This is something that can be improved.
