Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material delivery device, and more particularly, to an improvement of a sheet material delivery device for delivering a signature or the like to a predetermined position in a collating device or the like.

[0002]

2. Description of the Related Art For example, weekly magazines, magazines, etc. may be bound in a booklet or in a flat-stitched format. Will be supplied in sequence.

Here, the supply device 50 will be described with reference to the side view of the essential parts of the conventional book supply device 50 shown in FIGS. 5 and 6, the plan view of the support plate and the plan views of the feed belt and the conveyor belt. To do.

As shown in FIGS. 5, 6 (A) and 6 (B),
The first and second pulleys 51a and 51b are arranged in parallel, and the first
The pulley 51a side is arranged slightly higher. The first,
Three feed belts 52a, 52b, 52c are stretched between the second pulleys 51a, 51b, and two horizontal conveyor belts 54a, 54b are arranged between the second pulley 51b and the third pulley 53 arranged in parallel. Have been passed over. Above the second pulley 51b, a weir 55 made of hard rubber having a circular cross-sectional shape, which is a "blocking member", is disposed with a gap g, and is inclined leftward from the right outer peripheral surface of the weir 55. Support plate 5
6 stands upright. To the right of the first pulley 51a, the feed belt 52 is inclined in the same direction as the inclination direction of the feed belt 52, and the right end portion of the signature S is stacked and placed on the inclined surface. A member 57 is provided.

In this way, the feed belt 52 and the support plate 5
6. When the tilting member 57 and the like are tilted, when the signatures S are stacked on the feed belt 52, they are pressed in the direction of the weir 55, and the stacked signatures S have a gap g.
It is delivered one by one onto the conveyor belt 54 via the.

[0006]

However, the signature S
May be bent at the location indicated by reference symbol A in FIG. 5, and the bent side may be laminated on the side abutting the support plate 56. In such a case, as shown by the symbol B, the signature S may become higher on the support plate 56 side, and the signature S may not be smoothly discharged from the gap g.

Therefore, the present invention has been made to solve the above-mentioned problems, and even when the supporting plate side becomes higher when the signatures are stacked, the signatures can be smoothly folded one by one from the gap. It is an object of the present invention to provide a sheet-like material delivery device capable of discharging.

[0008]

In order to achieve the above-mentioned object, the present invention has a feed belt for feeding and feeding sheet materials such as a stack of printed books, and a gap for the feed belt. And a blocking member for feeding the stacked sheets one by one from the gap to the downstream side, and extending from the blocking member in a direction substantially perpendicular to the feed belt. And a support plate for abutting and supporting the side end surfaces of the stacked sheet-like products, the supporting plate presses the sheet-like products toward the feed belt. The pressing member was provided.

Further, a feed belt for feeding and feeding sheet materials such as stacked stacks of sheets, and a sheet arranged with a gap between the feed belt and the stacks placed from the gap. A blocking member for supplying the sheet-shaped products one by one to the downstream side, and a side end surface of the stacked sheet-shaped products extending from the blocking member in a direction substantially perpendicular to the feed belt. In a sheet-shaped article feeding device provided with a support plate for contacting and supporting the sheet-shaped article feeding device, the rear end portion side of the sheet-shaped articles stacked on the feed belt is placed, and An inclined member having an inclined surface portion for pushing out toward the support plate is provided, and the inclined surface portion of the inclined member is provided with a rotating member for rotating and transporting the stacked sheet-like objects.

[0010]

The leading end side of the sheet-like materials (folded sheets) stacked and placed on the feed belt is pressed against the blocking member (weir) and the support plate side by the rotation of the feed belt conveyance. On the other hand, by rotating a pressing member (pressing belt) provided on the support plate, the leading end side of the stacked sheet-like objects is pressed against the feed belt side, and the lowest sheet-like object is a blocking member (weir). From the gap formed between the feed belt and the feed belt, they are delivered one by one to the downstream side.

Further, the rear end portion side of the sheet-like materials stacked and mounted on the feed belt is mounted on a rotating member provided on the tilting member. Therefore, when the sheet-like material is conveyed to the blocking member side by the conveyance rotation of the feed belt, the sheet-like material is smoothly conveyed.

As shown in FIG. 3, the CPU 11 has an input unit 12 for inputting various instructions, data, etc.
When the paper quality and the speed of the feed belt are determined, the ROM 13 in which the speed data of the pressing belts 3a and 3b corresponding to them are stored in advance, the RAM 14 for temporarily storing the data of the processing process, and the ROM 13 A pulley drive motor speed varying unit 5 that varies the speed of the pulley drive motor 4 according to the read data, a feed belt motor speed varying unit 15 that variably rotates the feed belt 52, and a transport that variably rotates the transport belt 54. The belt motor speed varying unit 16 is connected.

Next, the operation of the sheet-like material feeding device configured as described above will be described with reference to the flow chart shown in FIG. First, the book S is stacked and placed on the feed belt 52. At this time, the front end of the book S is brought into contact with the support plate 1 and the pressing belts 3a and 3b, and the rear end of the book S is It is placed on the free bearing 7 (step S
1). Next, the operator inputs various conditions such as the paper thickness of the copy book S, the paper quality, the speed of the feed belt, the speed of the conveyor belt, and the number of sheets to be sent from the input unit 12 (step S2). Next, when the operator turns on the send start button (not shown) of the input unit 12 (step S3), the pressing belts 3a and 3b are optimized from the ROM 13 according to the paper thickness, paper quality, feed belt speed, transport belt speed, etc. The speed is selected (step S4). As described above, the copy sheet S is rotated by the feed belt 52 and is rotated by the pressing belt 3 as well.
It is pressed downward by a and 3b, and is delivered one by one to the conveyor belt 54 from the gap g between the weir 55 and the feed belt 52 (step S5). Then, the input unit 12 is set in advance.
When the transmission of the number of sheets input to is completed, a series of processes is completed (step S6).
