Description

Description: FIELD OF THE INVENTION The present invention relates to a collating machine that sequentially arranges signatures sequentially supplied to a signature conveyor from a plurality of magazines arranged side by side on a back side and stacks them in page order. Also, the present invention relates to a device for sending a reverse signature, which needs to overlap a fore side to the back side of the signature from the specification of bookbinding, to the conveyor during the collating process.

"Prior art" As shown in FIG.
Each of the 21 has a suction cup 22 attached to the bottom. The suction cup 22 sucks the back side P1 (fold side) of the signature P. The signature P sucked by the suction cup 22 is:
The spine P1 is sent to the opening / closing claw 24 of the supply drum 23 in the same direction, is sequentially stacked in the page order, and is conveyed by a signature conveyor 25 having a claw attached to a chain.

"Problems to be Solved by the Invention" However, as shown in FIG. 4, for example, in a booklet for learning, between the signatures P stacked with the direction of the back P1 aligned,
There is a case where it is necessary to bind a reverse signature W such as an answer sheet with the spine W1 directed to the fore edge P2 side of the signature P and the fore edge W2 directed to the spine P1 side. However, when the answer sheets are stored in one of the magazines 21 arranged in a row in the opposite direction, the suction cup 22 sucks the fore-edge side, so that the signature is opened and cannot be taken out of the magazine 21 or cannot be locked by the opening / closing claw 24. I will.

Therefore, in the past, reverse signatures such as answer sheets had no other means except to reduce the operating speed of the collating machine and manually supply them to the signature conveyor 25, which was extremely inefficient.

"Means for Solving the Problems" The present invention is intended to allow a reverse signature to be fed into a collating machine during a collating process in conjunction with a collating machine. The configuration is the gist.

During the collating process, drums that rotate in the same direction are arranged in two stages below the magazine that stores the reverse signature to be collated with the edge side overlapping the back side of the collated signature.

In the upper drum, a reverse signature, which is sucked on the back side by a suction cup from the magazine and supplied one by one, is sandwiched by the back side, is sent to the lower side of the upper drum with the back side forward, and is brought into contact with the stopper. The opening / closing claw and the claw pad to be opened later are provided, and the lower drum is provided with the opening / closing claw and the claw pad which are fed with the fore edge side forward when the back of the reverse signature abuts against the stopper and the fore side is forward. .

A thickness detection sensor that detects the thickness of the reverse signature sent by the upper drum and stops the feed if it is outside the allowable range, and a reverse signature holder that presses the reverse signature abutting on the stopper against the upper drum. And a delivery conveyor for supplying reverse signatures sent from the lower drum and released from the open / close claws to a signature conveyor of a collating machine.

The reverse signature input device of the present invention can be moved to an arbitrary position of the collating machine by using a caster or the like, and is linked with the collating machine in synchronization.

"Example" In FIG. 1 showing a side view of a main part, 1 is a frame, and 2 is a magazine installed on the upper part of the frame 1. Reference numeral 3 denotes a suction cup connected to a vacuum pump (not shown). The reverse signature W stored in the magazine 2 is connected to the back W1 through an opening at the bottom of the magazine 2.
It sucks from the side and pulls out one copy at a time. W2
Is the fork of the reverse signature W. The reverse signature W is accommodated in the magazine 2 with the spine W1 aligned in the same direction.

A drum 4 is rotatably mounted below the magazine 2. Reference numeral 5 denotes an opening / closing claw, whose base is fixed to a drive shaft 6 protruding from the side of the upper drum 4. When the opening / closing claw 5 is closed, the claw 7 protrudes from the outer edge of the side of the upper drum 4. Then, the folded four-claw W pulled out from the magazine 2 is sandwiched by the back W1 side and opened when opened. The opening / closing claw 5 and the claw pad 7 are
It is provided on both sides of the upper drum 4.

Reference numeral 8 denotes a lower drum, which is rotatably mounted below the upper drum 4. The opening / closing claw 9, its drive shaft 10, and the claw pad 11 are mounted in the same configuration as the lower drum 4. The upper drums 4 and 8 also rotate in the same direction, and counterclockwise in the illustrated example.

A stopper 12 is fixed to the frame 1 so as to sandwich the upper drum 4 from both sides. The stopper 12 is used for the suction cup 3
The reverse signature W pulled out in the step is sandwiched between the opening / closing claw 5 and the claw pad 7 on the side of the back W1, and is provided at a position where the back W1 comes into contact when the back W1 is moved forward and below the upper drum 4. Have been.
When the reverse signature W comes into contact with the stopper 12 and the edge W2 is caught between the opening / closing claw 9 of the lower drum 8 and the claw pad 11 near the contact point of the two drums 4 and 8, the opening / closing claw of the upper drum 4 is opened. 5, the reverse signature W is configured to move with the fore edge W2 in front.

Reference numeral 13 denotes a thickness detection sensor which stops the feeding if the thickness of the reverse signature W sent by the upper drum 4 is out of an allowable range. 14
Is a reverse signature holder, and when the reverse signature W moves below the upper drum 4, a cam is driven so as to press the reverse signature W against the upper drum 4 from below.

Reference numeral 15 denotes a delivery conveyor disposed vertically, which feeds the reverse signature W sent from the lower drum 8 to the delivery conveyor 15.
, The opening / closing claw 9 is opened, and the reverse signature W
Is released and sent to the signature conveyor 25 of the collating machine B.

Reference numeral 16 denotes a caster attached to the bottom of the frame 1. The caster A is moved to an arbitrary position of the collating machine B, for example, the position shown in FIG. 3 so that the reverse signature W can be stacked in a predetermined page order. Move to

Therefore, when the operation of the collating machine B is started with the loading device A placed at the position shown in FIG. 3, the side opposite to the spine P1 side (shown by oblique lines in the figure) of the signature P collated by the collating machine B. , That is, P2
, The back W1 side of the reverse signature W (shown by oblique lines in the figure) is overlapped.

The operations of the suction cup 3, the upper and lower drums 4, 8, the opening and closing claws 5, 9, the reverse signature holder 14, and the like are synchronized with the operation of the collating machine B.

[Effect of the Invention] Reverse collation, which has been conventionally thrown by hand, can be mechanically supplied in synchronization with the collating machine without reducing the operation speed of the collating machine, thereby increasing the efficiency of collation.
