Abstract

PURPOSE:To automatically feed signatures into a pocket in such a way that in an equipment to feed the signatures into the pocket for a collater, an elevator, an adsorbing roller, and a carrying conveyor are worked only by putting signature piled body on a feed conveyor. CONSTITUTION:When the number of signature in a pocket 3 becomes less, accumulated body (A) of the signature existing above is moved toward an elevator 1 by operating a feed conveyor 2, and after it arrives at a detector 38, the elevator 1 is operated, and the accumulated body (A) is lifted by a receiving plate. With this ascent, approach of the top part of the accumulated body close to an adsorbing roller 16 is detected by a detector 40, the accumulated body is temporarily stopped or lifted at a low speed, the signatures are adsorbed one by one starting from the signature at the top part by the adsorbing roller 16, and transferred onto a carrying conveyor 4. When the determined amount of the signature are collected through the conveyor 4 into the pocket 3, feed of the signature into the pocket 3 is stopped by action of a limit switch 37.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a signature feeding system for automatically feeding signatures into pockets for a collating machine.

When binding various books such as magazines and paperbacks, a predetermined number of printed pages that are part of the book, i.e., signatures, are stacked in a series of corresponding pockets, and one signature is inserted from the bottom edge of each pocket. Copies are taken out one book at a time and bound together. Therefore, each pocket must always store an appropriate amount of signatures in an unraveled state.Therefore, if the supply of signatures to the pockets is done manually, as in this case, a considerable amount of manual labor is required. Therefore, there is a strong desire to automate this work and save labor. In order to do this, the stack of signatures must be simply placed on a support stand or the like and sent to the pocket, be separated and unraveled into parts along the way, and be properly delivered into the pocket and stored in an aligned state. It is necessary to meet the requirements such as: .

SUMMARY OF THE INVENTION The object of the invention is to provide a signature supply system which satisfies the above requirements for automatically supplying signatures to the pockets of a collating machine.

A support plate (1) is installed on which the conveyor (4) is supported, and a support plate (1
A pocket (3) is installed at the end of 1).

Although it is preferable to include the pinch roller (6), it may be omitted depending on the case.

In the preferred form of the elevator (++, as clearly shown in FIGS. 7 and 8, the supports provided at the same height position are plate (1a); in the example shown, the six supports are plate (1a)). Each bridge has chain wheels (1b) and (lc) arranged above and below.
) is attached to a flexible transmission member such as a chain (1d), and the chain (1d) and bridge are attached to a plate (la
) is driven by a motor (I21) via a reducer (13). In this embodiment, the plate (1a) is reciprocated up and down by the forward and reverse rotation of the motor. (1a) is pivoted at its base (1e), the roller (If) at one end moves along the guide plate (1g), and the plate cannot rotate clockwise in Fig. 1. However, it can rotate counterclockwise.As shown in Fig. 2, the supply conveyor (2) consists of a pair of belt conveyors (2a). , each belt conveyor (2a) is connected to the transmission member 05 by the motor C141.
), this feed conveyor (2) serves as a support for the stacks of signatures, and in the case of a belt conveyor (2a) it can carry a plurality of, and even a considerable number of, stacks. can be supported. This supply conveyor (2
) is preferably provided with guide plates (2b) on both sides. In this case, the plurality of receiver plates (1a) are arranged in a comb shape so as to pass between the belt conveyors (2a) and the outside of each belt conveyor (2a).

The transfer device (5) includes a suction roller (16), and the suction roller (16) is rotatably provided on the support shaft 07 and communicates with the vacuum source 09 through the pipe (1&). 07) consists of a hollow shaft and has a suction roller (le
is connected to a vacuum source a9 via the support shaft 07). This suction roller has a series of holes (16a) around its periphery, which holes are curved one after another in communication with holes (17a) located on the underside of the hollow shaft Cl7). The suction roller 11119 is connected to a motor (2) installed on a support frame fixed to a support shaft (171).
Rotated by υ. More preferably, the support shaft α′
I) one end is pivoted and the other end is adjusted by means of an adjustment device -E
It is movable downward, the other end is connected to the rank (22) via a universal joint Cυ, and a binion rotated by a forward/reverse motor (23) engages with the rack (22).
It is designed to move up and down. A sensing device is included to sense the topmost signature supported by the elevator (1) and drive the motor (23). The forward/reverse motor, the rack/binion, and the sensing device constitute an adjusting device, and the suction roller (16) is adjusted to follow the topmost signature.

The signature sent by the transfer device fFi)K is placed in the pocket (3
) The conveyor (4) for conveying the material to (4) preferably consists of a pair of belt conveyors (4a), as shown in FIG.

Each belt conveyor is connected to a transmission member (
It is driven through two. In this case, the belt conveyor (
A pitch roller (6) is arranged at and between the outlet end of 4a). The pitch roller (6) is a pair of rollers (6a)
- the force roller is installed on the roller shaft of the belt conveyor (4a), and the other roller is an arm (6b) and a column (6c) connecting the arm with bolts or the like;
Preferably, the support is adjustable.

Additionally, the system of the invention includes lateral aligners (7) placed on the sides of the pocket (3), as shown in FIGS. 1 and 5. The horizontal alignment plate (7) performs reciprocating motion with a slight amplitude to horizontally align the signatures in the pocket (3), and for this purpose, one of the horizontal alignment plates is rotated by a motor (□□□). The arm attached eccentrically to the shaft (connected to mark 2, and connected to the other horizontal alignment plate (mark 7)
'') is connected to an arm (29) mounted eccentrically on the carrier (27') which engages with said carrier (27).

In addition, in the illustrated example, horizontal alignment plates (71, (7') are arranged on both sides of the pocket (3), but they do not necessarily have to be on both sides, and may be on one side.
It is preferable that the ends of the vertical plates forming the inner wall of Pokeno (31s) are adjustable so that they can move forward and backward to some extent, so that changes in the dimensions of the signatures can be easily accommodated.

In a preferred form of this system, the system is installed below the transport conveyor (4) and in pockets (4) as shown.
3) Move horizontally forward and backward at the relatively upper part of the area (.

6. This shutter device is provided with a receiving/receiving device (31), as clearly shown in FIG.
A rod-shaped member (32) installed horizontally on a book, a motor (33) that drives it to move forward and backward, an arm (34) rotated by the motor, and an arm (34)
The tip of the connecting rod (
35). In the figure, (36) represents each member (32
) is a guide. (37) in Figure 1 is the pocket (3
) for sensing the signatures in the elevator (1), a mitswitch or other type of sensing device (38) for sensing the stack of signatures fed to the elevator (1) by the feeding device (2); This is a sensing device such as a glue switch. (39) is the control panel. In addition, an appropriate number of sensing devices are installed along the guide plate (II) of the elevator (1),
These allow the receiver to sense the position of the plate (1a).

(40) is a device for sensing the lifted signature.

In operation, the system is activated when there are fewer signatures in the pocket (3). First, the stack of signatures (5) on top of the supply conveyor (2) is moved to the elevator (1) by the operation of the supply conveyor (2).
) and when it reaches the sensing device (38), the elevator (1) is activated and the receiver raises the stack (6) by means of the plate (1a) until the top of the stack reaches the suction roller. (16)
, the sensing device (40) detects this and temporarily stops the stack or raises it at a very low speed.
A suction roller [6] sucks up a portion of the uppermost signature and transfers it onto the conveyor (4). The plate (la) of the elevator (1) moves at high speed until it comes into contact with the stack of signatures and when going up the stack, and also descends at high speed due to the reverse rotation of the motor O2, and at that time, If the next stack is in the path of the plate (1a), the receiver hits it and rotates counterclockwise, passing through that stack and reaching underneath it. In the elevator (1), each signature is placed with its folded side facing inside. When a predetermined amount of signatures accumulate in the pocket (3), the supply of signatures to the pocket is stopped by the action of the limit switch (37).

In the transfer device (5), the inside of the support shaft 0η of the suction roller Q61 is in a vacuum, and when the hole (16a) of the suction roller rotating around it communicates with the hole (17a) of the support shaft, the hole creates a vacuum and suctions the signatures. Suction roller α
e rotates from the upper end of the elevator (1) toward the conveyor (4) as shown by arrow B, and its hole (16a) rotates while sucking the signatures. As the rotation of the suction roller momentarily causes that hole (16a) to communicate with the next hole (16a) as well as the hole (17a) in the support shaft, there is a residual vacuum for a short period of time, which weakens the signature. It's suctioning. Then, at the next moment, the next hole (16a) communicates with the support shaft (17a), attracts another position of the signature, and rotates in the same manner. Thus, each hole (16a) of the suction roller (1e) sequentially suctions and rotates the signatures, and transfers them onto the conveyor (4).

When the signature is transferred, if the distance between the suction roller (Ie) and the signature becomes too large, the motor Q3 lowers the suction roller ae via the rack handle, and when the signature rises, the suction roller 0 (
) will also be raised.

The signatures separated by the suction roller αQ and transferred onto the transport conveyor (4) are transported there at high speed and are further separated. Immediately before being fed into the pocket (3), each signature is pinched by a pinch roller (6) and dropped into the pocket (3) in an appropriate posture. In a preferred form, a shutter (31) is provided, in which case the signatures are temporarily stacked on the member (32), and when a certain amount has accumulated, one of the arms (34) is moved by the motor (33). The rotation momentarily causes the receiver member (32) to be retracted and dropped into the pocket. Therefore, since the drop when falling into the pocket is small, it is fed into the pocket (3) reliably and stably. Furthermore, the signatures dropped into the pockets (3) are side-aligned by the horizontal alignment plates (7). Therefore, according to the invention, it is possible to simply place the signature stack on the supply conveyor (2). Just by placing it, it is automatically fed into the pocket (3), and along the way, it is sucked in part at a time, so it is completely loosened. Once placed in a pocket, it is kept properly aligned within it. Therefore, it is possible to supply the signatures to the collating machine's bin in an extremely suitable condition.
