Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an edge aligning clamp device for a three-way cutting machine,
More specifically, the contact surface of the alignment bar that contacts the folded book is made to face the folded book edge at right angles to the table, and the forward of the alignment bar presses the spine of the signature on the table to the clamp stopper to clamp it. The present invention relates to an edge aligning clamp device for a three-way cutting machine.

(Prior Art) In the process of cutting a folded book, which has a cover attached to the printed book by a bookbinding machine, into three parts, the top, the ground, and the small edge, to make a book, press the folded book from the small edge to clamp it. The back of the folded book is clamped by closely adhering the spine of the folded book to the edge of the fore edge, and the cut is performed by moving it in the direction of the fore edge. It was extremely difficult to get close to.

(Problems to be solved by the invention) That is, in the related art, a mechanism for pulling and pushing the folded portion of the alignment portion on the table toward the clamp stopper side is folded as shown in FIG.
Since the contact surface 16'a contacting with 24a is due to the fan-shaped rotation restoring motion of the aligning rod 16a centering on the aligning shaft 13a which is fan-shaped, the uneven edge portion of the folded book 24a is pressed downward from above. It was not possible to pull it in on the clamp stopper side while attaching it, and it was impossible to pinch the book between the alignment bar 16a and the table 1a for accurate alignment. Further, since the position of the aligning bar 16a is always changed depending on the size of the book, a mechanically complicated combination of levers, cams, racks and the like is unavoidable. Thinner case of Orimoto 24a number of books of the many stacked, and to back t ₂ is higher than the book block t ₁ of Orimoto 24a as FIG. 4, back to the clamp stopper 20a as in the fifth diagram t It was very difficult to bring the _two into close contact.

(Means for Solving Problems) The present invention has been made to solve the above problems and is configured as follows.

That is, the edge aligning clamp device of the three-way cutting machine of the present invention is
A sliding body that is slidable along a horizontal guide shaft above the table and has a rotary actuator, a reciprocating mechanism mounted on the guide shaft to move the sliding body forward and backward, and an alignment shaft by the rotary actuator. It consists of an alignment bar that rotates and restores to the shaft, and a clamp stopper that clamps the folded book with its spine closely contacting the stopper. The contact surface of the aligned bar that comes into contact with the folded book is in the direction perpendicular to the table. It is characterized in that the spine of the signature of the aligning part on the table is pressed against the clamp stopper by the aligning bar so as to face the clamp stopper.

Next, the edge aligning and clamping device of the three-way cutting machine of the present invention will be described in detail with reference to the following embodiments with reference to the drawings.

[Embodiment] First, 2 and 2 are horizontal guide shafts above the table 1 which are laid in parallel with the support rods 3 and 3 on both the left and right sides. A slide body 4 equipped with a rotary actuator 10 is slidably mounted on the right side of the guide shafts 2 and 2 with a slide bearing 5 interposed therebetween, and a gripping portion is sandwiched on the left side thereof. An integral retracting cylinder 7 is provided on a bracket 8 fixed to the guide shafts 2, 2. The tip of the piston rod of the pull-in cylinder 7 is connected and fixed to the rear end of the sliding body 4 to form a reciprocating mechanism 6 for moving the sliding body 4 forward and backward. As the reciprocating mechanism 6, various devices such as a magnet and a cam transmission mechanism can be used in addition to the retracting air cylinder. 13 is the sliding member 4
A longitudinal alignment shaft horizontally supported by the upper bearing 12, and two alignment rods 16 and 16 having an abutment surface 16 'for contacting the folded book 24 are spaced apart from each other on the alignment shaft 13. The base ends are fixedly provided. Then, the gear 14 fixed to the rotary shaft 11 of the rotary actuator 10 and the gear fixed to the alignment shaft 13 are fixed.
15 is meshed with each other, and both alignment rods 16 and 16 are rotated and restored by the rotary actuator 10 about the alignment shaft 13. 17 and 18 are rotary actuators 1.
0, a solenoid valve that operates the retracting cylinder 7.
Further, 19 is a feed stopper at the aligned position on the table 1, 20 is a clamp stopper for clamping the back of the folded book 24 in close contact with the stopper 21, and 22,
Reference numeral 23 is the upper and lower clamp plates. Further, 25 is a pressing plate for pressing the fore edge side of the folded book 24 so as to be operated by the pressing cylinder 26. In the present invention, the contact surface 16 'of the aligning bar 16 which contacts the folded book 24 is made to face the fore edge of the folded book 24 in the direction perpendicular to the table 1 so that the folded bar 24 of the folded section 24 on the table 1 is aligned by the aligning bar 16. The back is pressed against the clamp stopper and clamped.

[Operational state of the embodiment] When the folded book 24 is fed to the alignment section on the table 1, the solenoid valve 17 operates and the rotary actuator 10 rotates 90 °. Therefore, the alignment shaft 13 is moved through the gears 14 and 15 transmission mechanism.
Rotate 90 ° to the right and the aligning rod 16 at the upper chain line waiting position rotates 90 ° and moves to the position shown by the solid line in FIG. The contact surface 16 'of the aligning bar 16 that contacts the folded book 24 is perpendicular to the table 1,
In addition, it is facing the small edge of the 24-fold book. Next, the pull-in cylinder 7 is operated by the solenoid valve 18, and the slide body 4 is moved to the left pull-in cylinder 7 side, so that the aligning rods 16 and 16 come into contact with the folding book 24 at a right angle to the table 1. , Press the folded book 24 toward the clamp stopper 20. At the same time, the presser cylinder 26 operates and the presser plate 25
Push down. And the clamp stopper 20 is folded
Clamp 24 exactly. Then, when the clamp stopper 20 clamps the folded book 24, the pressing cylinder 26, the retracting cylinder 7 and the rotary actuator 10 are released, and the initial state is restored.

(Effects of the Invention) The device of the present invention has the above-described configuration, and the contact surface of the aligning bar that comes into contact with the folded book is made to face the folded book edge in the direction perpendicular to the table, and the folded bar of the table top aligned section is folded by the aligned bar. Since the spine is pressed against the clamp stopper and clamped, the spine of the folded book is closely aligned with the stopper to ensure accurate alignment, a stable clamp is guaranteed, and the back of the spine is thin even when the number of stacked books is large. It has an outstanding effect such as tight and stable clamping.

Further, according to the present invention, since the pressing plate for pressing the small side of the folded book is provided, the bending of the folded book is pressed in the clamp stopper direction and at the same time, the pressing plate is pushed downward to remove the bending of the leading end of the folded book. At the same time, there is an excellent effect that the air in the folded book is pushed out and the folded book can be clamped in a stable state.
