Abstract

PURPOSE:To permit folded leaves to automatically drop straight into a pocket by sucking one by one folded leaves lifted by an levator with a suction roller and transferring automatically the leaves into the pocket for a leaf aligning machine while sucking them to the lower surface of a conveyer belt. CONSTITUTION:A laminate A of folded leaves is moved to an elevator 1 by the operation of a supply conveyer 2 and lifted by a carrier plate 11. When the uppermost portion of the laminate A approaches a suction roller 25, the suction roller 25 sucks one by one the folded leaves to mount them on a transfer device 4 in which a conveyer belt 34 circulates around a vacuum box 33. Respective holes 44 in the conveyer belt 34 communicate to a hole 43 in the vacuum box 33 on the lower side position to be evacuated so that the folded leaves sequentially sent from the suction roller 25 are sucked to the lower surface of the conveyer belt 34 to be sent to a pocket 3. Since the hole 44 does not communicate to the vacuum box 33 at an end of the outlet side of the conveyer belt 34, the folded leaves drop into the pocket 3.

Description

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

When binding various books such as magazines and paperback books, a predetermined number of printed pages that are part of the book, i.e., signatures, are stacked in a series of corresponding pockets, and a portion of the signatures are removed from the bottom edge of each pocket. The books are taken out one book at a time and then bound together. Therefore, each pocket must always store an appropriate amount of signatures in an untangled state. If we relied on humans to supply signatures to the pockets as before, it would require manual labor for five signatures.
There is a growing need to automate this work and save labor. This requires that the stack of signatures is simply placed on a support and sent to the pocket, that it is separated and unraveled into sections along the way, and that it is properly dropped into the pocket and stored in an aligned state. It is necessary to meet the requirements such as:

j7 In a conventional signature supply device, the signatures lifted by a lifting device are transferred onto a transport conveyor, and then dropped into pockets while being thrown by a pair of pinch rollers provided at the exit end of the transport conveyor. Because it was a thing,
They had the disadvantage that they could not fall straight, were fed in a bent state, and were not stacked correctly in the pocket.

28), and the inside is evacuated. As shown in FIG.
) Preferably, there is a table (g) between the upper end of the pocket (3) and the pocket (3).

The conveyor bell) l34) is hung on rollers C37) and □□□ placed at both ends of the vacuum box, and the support plate (10
) The motor (41
η, it is driven through a transmission part (40). 142 in Figure 7 is a vacuum source (2 barrels As shown in Figures 7 and 8, vacuum box C1: (+ Holes (43) are provided in the direction, and the holes (43) may be provided on both sides at appropriate intervals in the longitudinal direction as shown in the figure, but may also be a series of elongated holes elongated in the width direction. , or may be in the form of a slit extending in the longitudinal direction.The arrangement and shape of these holes (orifices) are not particularly limited.

The conveyor belt C31 has holes (44) provided at appropriate intervals in the longitudinal direction, and in the example shown in FIG. 7, the conveyor belt C31 is constructed from a single wide belt. , a series of holes +441 are formed on both sides thereof.

These holes (44), as seen in FIG. In some cases, it may be composed of a plurality of belts, for example, as shown in FIG. 9, two belts (34a), (34
b), in which case each belt has a series of
□ hole (44J is provided.

The lateral alignment device (6), as shown in FIG. This method performs a reciprocating motion with amplitude to horizontally align the signatures in the pocket (3). Figure 10 shows an example of this, in which the horizontal aligning plates (four are rotated by motor 1) An arm (49) eccentrically attached to the gear (47) that is connected to the carrier (47) and connected to the other horizontal alignment plate (45'); It is preferable that the vertical plate t!N011- forming the inner wall of the pocket (3) is adjustable so that it can be moved forward and backward to a certain degree, thereby easily changing the dimensions of the signature. can be accommodated.

In addition, in a preferable form, a shutter device that moves horizontally in the relatively upper part of the pocket (3) is installed, and the falling signatures are temporarily stopped in the middle of the pocket, and when a certain amount remains, the shutter device is installed in the pocket (3). It can be dropped inside. Although not shown in the figure, a sensing device such as a limit switch is installed at an appropriate position in order to sense the signatures in the pocket and the stack of signatures sent by the supply conveyor (2). and a control panel are installed.

In operation, when there are fewer signatures stored in the pocket (3), the signature feeder is activated. First, the supply conveyor (2) is operated to cause the stack of signatures (A
) is moved towards the elevator (1) and reaches the associated sensing device, the elevator (1) is actuated and the receiver raises the stack (A) by means of the plate 0υ, until the top of the stack reaches the suction roller. When it comes close to C, the sensing device at that position detects this, and the stack is temporarily stopped or raised at a very low speed, and the suction roller (the two suction rollers suck one part at a time) from the top signature. Transfer to unloading device (4).Elevator (1)
The receiving plate (1υ) moves at a relatively high speed until it comes into contact with the stack of signatures and when moving up the stack, and is also moved at high speed when the motor 09 is reversed and lowered. If the laminate is in the path of plate 00, it will hit it and rotate counterclockwise, passing through the laminate and reaching that page.In addition, at the elevator (1) position, each signature is It is installed so that the bent side is inside.Pockets (3
) When a predetermined amount of signatures have accumulated in the pocket, the supply of signatures to the pocket is stopped by sensing this or by the action of a mint switch.

During the transfer from the elevator (1) to the unloading equipment R (4), the interior of the support shaft ee of the suction roller (29) is in a vacuum, and the hole (25a) of the suction roller rotating around it is
) communicates with the hole (26a) of the support shaft as shown in FIG. 4, the hole becomes evacuated and the signatures are sucked.

The suction roller (C) rotates from the upper end of the elevator (1) toward the unloading device (4) as shown by arrow B (Fig. 1), and its hole (25a) rotates while sucking the signatures. do.

Due to the rotation of the suction roller, the hole (25a) instantaneously communicates with the next hole (25a) and the hole (26a) of the support shaft, so there is a residual vacuum for a short period of time, which weakens the signature. It's suctioning. And in the next moment, the next hole (25
a) communicates with the hole (26a) of the support shaft, attracts another position of the signature and similarly rotates. Thus, the suction roller (
Each of the holes (25a) in (c) sequentially sucks in the signatures, rotates them, and transfers them to the unloading device (4). Preferably, if the distance between the suction roller c2 and the signature becomes too large during the transfer of the signature, the motor 04 also raises the roller (c) via the rack c31+.

In the unloading device (4), the conveyor belt (B) circulates around the vacuum phase country, and each hole (44) of the conveyor belt 04) is evacuated through the hole +43K4 of the vacuum box C33 at the lower position. Therefore, the signatures (A) sequentially sent from the suction roller (c) are attracted to the lower surface of the conveyor belt C34) and sent toward the pocket (3), as shown in FIG.

The signatures attracted to the conveyor belt 04) are separated from each other as they are fed there at high speed. This conveyor belt C34)
The outlet end of the pocket (3) is located approximately at the center of the pocket (3);
At this end and in the vicinity thereof, there are holes (44) in the conveyor belt.
) will no longer communicate with the vacuum box (to), so the signature will fall from directly above pocket (3) due to gravity, and will fall into pocket (3).
3) It is sent inside. The signatures dropped into the pockets (3) are side-aligned by a side-aligning device (6).

Therefore, according to the present invention, by simply placing a stack of signatures on the supply conveyor, the stack of signatures is automatically fed into the pockets of the collating machine, and the signatures are straightly and straightly placed in the pockets. It can be dropped in a stable state.
