Description

[Detailed description of the invention]

[Field of Application of the Invention] The present invention relates to printed matter (with folds) conveyed from a folding machine.
The present invention relates to a printed matter conveyance/output line that stacks a predetermined number of printed copies (hereinafter referred to as printed copies), bundles and transports them, and particularly relates to a printed book stacker that stacks printed copies by a predetermined number of copies. [Background of the Invention] As shown in FIG. 1, the line for transporting and discharging printed books includes a folding machine 4 that folds printed matter printed by a rotary press 2 into a predetermined shape;
It is comprised of a stacker 10 that stacks the printed books 5 conveyed from the folding machine 4 into a stack of printed books of a predetermined number of copies, and a pandora 50 that binds the printed book stacks carried out from the stacker 10. The reference numeral 43 is a plunger that pushes the book stack accumulated in the stacker 10 and carries it out to the band 250, the reference numeral 60 is a hopper, the reference numeral 70 is a weir device,
Reference numeral 80 is a book transport conveyor. In the stacker IO, the printed books conveyed from the folding machine 4 are once received by a fork 12, and a predetermined number of copies (
For example, each time 30 or 50 copies are accumulated, this small stack of printed books (hereinafter referred to as a frame) 6 is dropped downward and accumulated on the turntable 14 below the fork 12. In addition, the top 6 has a back 6A and a fore edge 6 as shown in FIG.
B and B have different thicknesses, and in order to stack several frames in an orderly manner, it is desirable to form the stack so that the spines 6A of the frames are alternately cut out on the left and right sides, as shown in FIG. Therefore, the turntable 14 in the stacker lo is periodically rotated by 180 degrees so that the pieces 6 can be stacked in the form shown in FIG. 3. Also, when stacking the frames 6 in the stacker 10, the frames 6
Guides 16 are installed vertically on the turntable 14 in correspondence with the top, bottom, left and right sides of the falling pieces, but in order to stack the printed books in an orderly manner, the distance between the guides that face each other in the front, back, left and right directions must be adjusted. It is desirable to arrange the paper so that it is larger than the size of the printed book. In addition, in the high-speed printing book conveyance line, it is necessary to turn the turntable 14 in the stacker 10 at a fairly high speed of one revolution every 1.3 seconds, and the stack of printing books accumulated on the turntable is In order to prevent collapse, it is desirable to arrange the guide 16 as close to the side of the piece as possible. However, if they are brought too close together, the path for the pieces to fall will be narrow9, and there are disadvantages in that it is desirable for the pieces to fall smoothly. Conventional book stackers cannot simultaneously satisfy the two objectives of smooth falling of the frames and prevention of load collapse when the turntable rotates, and one or the other has been sacrificed. [Object of the Invention] The present invention has been made in order to eliminate the drawbacks of the above-mentioned prior art. A printing book that enables both the smooth handling of printing books and the prevention of load collapse due to high-speed reversal of the turntable, by making the guide interval expandable and contractionable, and by expanding and contracting the guide interval according to the movement of the temporary receiving plate. Our goal is to provide stackers.

[Embodiments of the Invention] Next, embodiments of the book stacker according to the present invention will be described based on the drawings. 4 to 10, the book stacker 2 according to the present invention
An example in which the printer 1 is incorporated into a printing book conveyance/output line will be described. As shown in FIG. 4, the book stacker 21, like the conventional book stacker, includes a fork 22 for accumulating the print books and dropping them downward frame by frame, and a fork 22 that is placed below the fork 22 and periodically A device consisting of a turntable 24 that rotates and reverses each frame by 180 degrees to receive frames and accumulate printed books, and a guide plate 26 that is vertically installed on the turntable 24 and faces front and back and left and right to form a path for the printed books to fall. The turntable 24 has a dual structure including a book receiving plate 24A having an outer shape that matches the outer shape of the printed book, and a rotating plate 24B disposed below the receiving plate 24A. The book receiving plate 24A is connected to the tip of a cylinder condo 28A of an air cylinder 28 disposed within the frame of the rotating plate 24B, and is capable of vertically sliding. The plate receiving plate 24A is adjusted to gradually descend at a constant speed from the position shown in FIG. 10 to the position shown in FIG. Care has been taken to prevent the printing from being disturbed and to reduce noise. The rotating plate 24B is fixed to a rotating shaft 29, and the rotating shaft 29 is rotated by gear mechanisms 31A and 31B between the driving shaft of the actuator 30 installed adjacently at a reversing speed capable of reversing back and forth in 1.3 seconds. It is designed to be reversed. As shown in FIGS. 6 to 9, the book plate receiving plate 24A has
Swivel plate 24BK vertically installed vertical guide rod 28B
passes through the plate, so that the book plate receiving plate 24A can rotate together with the rotating plate 24B. As shown in FIG. 5, the printed book 5 is conveyed by the conveyor 80 with the folded portion positioned on the left side in the conveying direction, placed into the hopper 60, and placed on the fork 22 in this state. However, since the center line 80A of the conveyor 80 and the center position 82 of the booklet receiving plate 24A are arranged to be offset from each other, the booklet receiving plate 24A has an edge portion as shown in FIG. The printing books are assembled (K) with the printing book stack 6B protruding in the left-right direction, so that the spine 6A will not be damaged even if the book stack is tied together. Board 26
A is fixedly raised at an interval corresponding to the horizontal length of the booklet 5, touches the side edge of the booklet receiving plate 24A, and extends to the vicinity of the fork 22. These left and right guide plates 26A function as guides for the left and right (111) sides of the piece. As shown in Figures 6 and 9, the turning, slope 24B
Two small rods 32 are formed to protrude outward from both front and rear edges of the , and a sliding member 33 - having a rod insertion hole is slidably attached to the small rods 32 . A compression spring 34 is attached to the slide member 33, and the sliding member 33 is biased inwardly. Two core frames 35 are vertically disposed on the sliding member 33 at an interval corresponding to the left-right length of the book. Both ends 3 of sliding member 33
3A is provided with a vertical insertion hole 33B.
A 3BK core rod 35 is rotatably inserted. A front and rear guide plate 26B is attached to the side surface of the core frame 35 by welding, and a torsion spring 36 installed between the core frame 35A and the sliding member 33A causes the front and rear guide plate 26B to move as shown in the white arrow in FIG. It is always biased in the direction shown in . In FIGS. 6 and 7, reference numeral 37 is a stopper protruding from the lower end of both ends 33A of the guide member, and the core frame 3
5. The bottle 35A protruding from the outer periphery of the lower end is the stopper 3.
7 to prevent the guide plate 26B from swinging more than necessary even if the distance between the front and rear guide plates 26B is expanded. A solenoid 40 having a slider 39 that slides in the front-rear direction is provided on the rotating plate 24B, and the slider 39 can come into contact with a plate 38 formed to protrude upward from the sliding member 33. A photosensor 41 installed above the tip of the fork 22 detects the movement of the tip of the fork 22 and sends a signal to the solenoid 40, and the slider 39 pushes the front and rear guide plates 26B outward. The space between the front and rear guide plates is expanded. Further, in the center of the sliding member 33, there is provided a pole 33B that comes into contact with the side edge of the rotating plate 24B.
The expansion/contraction distance of the guide plate 26B can be adjusted by adjusting the position of the guide plate 3B. A groove 42 extending in the front-rear direction is formed in the booklet receiving plate 24A, and a pushing plate 44 of a pusher 43 installed at the rear of the stacker slides back and forth along this groove 42. A conveying table 51 of the Pandora 50 is arranged close to the book plate receiving plate 24A, and a groove 52 of the same size as the groove 42 is formed in this table 51, and a sliding member is inserted into this groove 52. A front abutment plate 54 is fixed to this sliding member 53 and is capable of coming into contact with the front side of the book collection X'Jt body. It is placed so that it can be slid along. Inside the frame 50A of the Pandora 50, a pulley 55 (55A
, 55B) are installed, and a weight 57 is connected to the front end of the sliding member 53 via a wire 56, and the wire 56 is wound around the pulley 55 so that the front abutment plate 54 always applies a constant force. It appears to be in a state of being pushed backwards. Therefore,
After the front abutment plate 54 is pushed by the push plate and slides into the Pandora 50, the front abutment plate 54 is pushed by the weight of the weight 57.
is now able to return to its original position. Next, we will explain the operation of the printing book conveyance/output line based on Figures 10 to 17. In Figures 1o to 17, the blue frames are shown in white, and the edges are shown in diagonal lines. It is shown. First, as shown in FIG. 1O, printed books are successively fed into the hopper Go, and when a predetermined number of printed copies, for example, 50 printed copies, are accumulated on the fork 22, the scraping device 70 is activated and the hopper Go is loaded with printed books. The fork 22 stops feeding the first printing book.
Move in the direction of the arrow in figure 0 and let the piece fall downward. As shown in FIGS. 10 and 11, the book plate receiving plate 24A is located at the optimum position to receive one frame, and the photo sensor 4
1 detects the movement of the fork 22 and activates the solenoid 40, and the slider 39 slides outward to move the front and rear guide plate 26.
Since the space between the front and rear guide plates is widened by pushing B apart, the pieces fall smoothly. When the fork 22 drops the frame, it returns to its original position and the squeezing device 70 also begins to flow the printed books again, so that printed books are accumulated on the fork 22 again. On the other hand, as soon as the book plate receiving plate 24A receives the frame, the solenoid slider 39 returns to its original position, and the left and right guide plates 26B return to their original positions and come into contact with the left and right side edges of the frame. 2 In this state, the turntable 24 is moved back and forth by 180 degrees together with the top by the actuator 30, and at the same time, the book receiving plate 24A is lowered to the position shown in FIG. 12 and stands by at this position. During this time, the printed books are accumulated on the fork 22, and the first
As shown in FIG. 3, the serging device 70 operates to stop the flow of printed books, and the forks 22 and 13 move to drop the blocks. At this time, the solenoid 40 is actuated by the photo sensor 41, the distance between the front and rear guide plates 26B is widened, and the top falls smoothly. When the frame falls onto the book plate, the front and rear guide plates 26B return to their original positions and clamp the frame, and the book plate 24A, with the frame on it, moves back and forth 180 degrees and descends. Wait and attack at the position shown in Figure 14. . During this time, a predetermined number of copies are accumulated on the fork 22, and as shown in FIG. 15, the front and rear guide plates 26B are expanded to receive the next frame. Next, when a predetermined number of sesame seeds are accumulated on the booklet receiving plate 24A, the pusher 43 is activated and the pushing plate 44 pushes the booklet stack on the booklet receiving plate 24A, as shown in FIG. As shown in FIG.
The front guide plate 26A is pushed apart left and right against the inward biasing force of 6B, and the front side of the printed book is brought into contact with the front abutment plate 54 on the conveyance table 51. Further, as shown in FIG. 16, the book stack is pressed by the push plate 44 and combed out into the Pandora 50 while keeping the front abutment plate 54 in contact with the front side of the book stack. The pushing plate 44 that pushes the stack of printed books is formed by grooves 42 formed in the printed book receiving plate 24A and the conveying table 51, respectively.
．． Since it slides inside the Pandora 52, all the printed books are sent into the Pandora 50. When the stack of printed books bound within Pandora 50 is sent to the next stage, the pushing plate 44 returns to its original position, and the front abutting plate 54
returns to its original position by the action of the weight 57's own weight K. Furthermore, the empty book receiving plate 24A is placed in the air cylinder 28.
Accordingly, the robot rises to the optimum position to receive the first frame shown in FIG. 10 and waits. Then, the same operation as described above is repeated again, and the book stacks are transported and unloaded one after another. According to this embodiment, the following effects can be achieved. (1) Since the book stacker 21 is arranged offset from the center line 80A of the transport conveyor 80, it is possible to stack the book blocks so that the spine is inward from the edge as shown in FIG. You no longer have to worry about hurting your back. (11) Since the distance between the front and rear guide plates 26B is widened when the printing books are on the way and narrowed when the turntable is rotating, the printing books can be stacked without preventing them from falling and without disturbing the printing books. (iii) When pushing the buttons, the front side of the stack of prints is pressed in the opposite direction to the pushing direction of the buttons by the front abutment plate 54, so the prints are disturbed when being carried out into the Pandora of the stack of prints. It can be carried out without any problems. Since it is attached so that it can be opened and closed, it can be carried out regardless of whether the number of frames in the stack of printed books is odd or even. Since the front and rear guide plates 26B are still biased so as to press the front and rear side edges of the book stack, it is possible to reliably prevent the print books from being disordered J1 when carrying out the book book stack into Pandora. can. Next, another embodiment of the book stacker according to the present invention will be described. 18 to 21 show an example in which this second embodiment is applied to a printing book conveyance/unloading line.
The main feature is that the omeme structure is on the same ground. Other parts that are the same as those in the first embodiment 11i1j are designated by the same reference numerals, and the explanation thereof will be omitted if necessary. In FIG. 18, left and right opposed guide plates 26A are fixed and raised to the turntable 24B that constitutes the turntable 24 of the book stacker 2LA, corresponding to the left and right width of the book book, and the left and right opposing guide plates 26A are fixed to the turntable 24B of the book stacker 2LA. On the other hand, the front and rear facing guide plates 126B are arranged so that their front and back spacing corresponds to the front and rear length of the printing book, and are in contact with the front and rear edges of the rotating plate. The situation is as follows. As shown in FIG. 19, the rotating plate 24BK has four grooves 102 (102A, 1 '02
B, 102C, 102D) are formed, and this groove 1
There are four sliding members 104 (104A, 104B,
104C, 104D), and the sliding members 104A and 104C and the sliding members 104B and 104D are connected to each other by a connecting member 106. A front and rear guide plate 126B is attached to the connecting member 106, and the front and rear guide plate 126B is arranged so as to be able to slide integrally with the sliding member 104 in the front and rear direction. In addition, as shown in FIGS. 19 and 20, the rotating plate 2
A pulley 108 is pivotally attached to 4B, and extends to the tip J ],
The wire 112 to which 0 is attached is wound around the pulley 108 and connected to the connecting member 106, and the front and rear guide plates 126
B is in a state of being pulled inward by the weight of the weight 110. A solenoid 40 is installed on the swivel plate 2+B, and its slider 39 is in contact with the connecting member 106 at 7°, and the solenoid is activated in response to a signal from a photosensor 41 installed above the fork tip. The slider 39 of 40 slides, and the space between the front and rear guide plates 126B expands and contracts in accordance with the fall of the frame from the fork 22.By expanding and contracting the front and rear guide plates 126B, the book is placed on the book tray. Since the action of accumulating on the plate 24A is the same as that of the first embodiment of the present invention, the explanation thereof will be omitted. Note that the reference numeral 114 is a weight casing installed on the lower surface of the turning plate 24B, and when the turntable 24 turns, the weight 11
This is to prevent zero fluctuation. An auxiliary table 118 having a floor surface of the same height is provided. This auxiliary table 118 has four grooves 116 of the same size as the grooves 102 formed in the rotating plate 24B.
(116A, 116B, 116C, 116D) are formed in the front-rear direction, and the sliding member 104 moves inside these grooves 116.
can slide, and the front and rear guide plates 126B are connected to the transport table 51.
It is designed to be able to slide back and forth within the slit 115 of A. Therefore, the stack of printed books pushed by the pusher 43 is conveyed into the Pandora 50 with its front side pressed by the guide plate 126B. When the book stack is bundled within the Pandora 50 and transported to the next process, the guide plate 126B returns to its original position within the slider due to the tension of the weight 110. Note that the reference numeral 120 is a support member that supports the transport table 51A from below. According to this embodiment, in addition to the effects (1) and (11) of the first embodiment, the following effects occur. Since the guide plate 126B always presses the front side of the book stack with a constant force, the book stack can be transported from the stacker to Pandora at high speed without disturbing the book stack. In addition, since the guide plate 126B has a function equivalent to the front plate of the first embodiment, there is no need to provide a separate member in front of the stacker so that it can come into contact with the front side of the book stack, and the Pandora structure can be summarized concisely. [Effects of the Invention] As is clear from the above description, according to the present invention, it is possible to prevent the frames from falling and to prevent the book from being disturbed when the turntable rotates. Therefore, by using the present invention in a high-speed transporting and unloading line for printed books, high-speed processing of transporting and unloading the printed books becomes possible.
