Description

[Detailed description of the invention] (Field of industrial application) The invention is based on a path that transports a rectangular bundle of signatures, such as a bundle of newspapers, produced by a counter stacker in the longitudinal direction and advances to a film wrapping machine. In,
The present invention relates to a bundle direction changing device in a printed matter signature bundle conveyance path for changing the direction of a signature bundle to match a film packaging machine.

(Prior Art) The speed at which printed materials such as newspapers come out of a rotary press is currently about 150,000 copies per hour, and on one side of the rotary press, the rate is half that, 75,000 copies.

The printed materials are then folded, stacked one on top of the other at a constant pitch to form a row, are released from the holding device by an unloading device, and are conveyed to a counter stacker.

This will be explained with reference to FIGS. 8 and 9.

In FIG. 8, a printed document 23 is carried by a carrier 21 into a counter stacker 22a and/or a counter stacker 22b.

A bundle of signatures P discharged from the counter stackers 22a and 22b with the short side perpendicular to the discharge direction.
teeth. The direction of the bundle is changed by 90 degrees from the waiting conveyors 24a and 24b using bundle direction changing devices 27a and 27b,
Waiting conveyor 24a, 24b, right angle transfer device 26a, 26b, waiting conveyor 24a,
24b and film wrapping machines 30a and 30.
b, and further banding is performed by binding machines 31a and 31b.

The film wrapping machine 30c and the binding machine 31c are for fractional bundles, and the edge of the signature bundle P carried into the machine is perpendicular to the carrying direction.

The bundle direction changing device 27a transfers the signature bundle P to the packaging machine 3.
0a, 30b, 30c, and any packaging machine 3 can be loaded from the counter stacker 22b.
It can also be transported to 0a, 30b, and 30c.

In FIG. 9, bundle direction changing devices 27a, 27
The rotary table 14 of b is provided with a long taper roller 11 and short taper rollers 12, 12, and a belt conveyor 1 that can be raised and lowered.
3 and 13 are provided.

When the bundle of signatures P on the waiting conveyor 24a changes direction to the left, turn the rotary table 14 so that the thicker side of the tapered roller 11 is on the right side and keep it at a 45 degree angle, as shown in FIG. 13 is lowered from the surfaces of the tapered rollers 11 and 12.

The direction of the signature bundle P is changed by the thick portions of the rollers 11 and 12 where the peripheral speed is high, and the signature bundle P is discharged as a signature bundle P''.

Similarly, the direction can also be changed to the right as shown in Figure A.

In addition, by arranging the belt conveyor 13 parallel to the traveling direction of the signature bundle P, as shown in FIG.
is conveyed as it is toward the signature bundle P''.

(Problem to be solved by the invention) When the signature bundle P is transported from the counter stacker 22a to the packaging machine 30a and from the counter stacker 22b to the packaging machine 30b, the packaging machine 30
If there is no failure in a, 30b, the bundle direction changing device 2
The directions of 7a, 27b and the rotary table 14 may be constant.

However, when the packaging machine 30b breaks down, the bundle of signatures P from the counter stacker 22b needs to be turned to the left by the bundle direction changing device 27b, and the bundle direction changing device 27a needs to be moved straight in the same direction. . To do this, the device 27a is rotated as shown in FIG. 9C and then moved straight. However, in the same device 27a, it is necessary to rotate the direction of the object transferred from the counter stacker 22a again as shown in FIG.

In this way, the orientation of the rotary table 14 must be changed frequently as required, which inevitably takes a lot of time and significantly reduces the transfer capacity.

Moreover, these conventional bundle direction conversion devices 27a, 27b
In this case, the final direction of the bundle of signatures cannot be regulated reliably, so the bundle of signatures P is not necessarily parallel to the direction of travel, and if it is a large bundle, it will rotate too much, and if it is a small bundle, it will not rotate enough. Therefore, there is a drawback that the angle of direction change is not constant.

The present invention attempts to eliminate such drawbacks.

(Means for Solving the Problem) A conveyor is provided for transferring a rectangular bundle of signatures on the table.

A stopper device is provided along one side of the conveyor.

This stopper device consists of a stopper plate whose lower edge has a slight space between it and the top surface of the table, and two stoppers located at both ends of the stopper plate. It is provided so as to be movable forward and backward with respect to the bundle of signatures so as to engage with the side ends of the bundle of signatures.

A rotary conveying body made of a belt or roller is provided across the conveyor at right angles to the direction of movement of the conveyor and facing the stopper device.

This rotary transfer body engages with the stopper device and touches the bottom surface of the signature bundle that is changing direction.
It comes into contact with the direction of travel of the bundle at a substantially right angle, lifts the bundle of signatures, transfers it toward the stopper plate, and changes the direction of the bundle by a required angle. For this purpose, the rotary transfer body is provided so as to be able to appear and retract from the bottom surface of the signature bundle transferred by the transfer conveyor so that it can be raised above the surface of the transfer conveyor and transferred toward the stopper.

Furthermore, the coefficient of friction between the bundle of signatures and the transport conveyor is lower than the coefficient of friction between the papers of the bundle of signatures.

(Function) When a bundle of signatures is carried into this device, it is moved in that direction by the conveyor, but at this time, the side edge of the bundle of signatures engages with a stopper device that extends into the transfer path. For this purpose, the bundle of signatures is changed direction by a required angle, for example, 90 degrees, while contacting the stopper device.

Direction change using this stopper device is completely
A 90 degree conversion is impossible, and is approximately 70-80% of the conversion.

However, at this time, a rotating conveyor such as a belt or roller advances and contacts the bottom surface of the bundle of signatures, raising it above the transfer surface of the conveyor, and the bundle of signatures is transferred to the belt or roller forming the rotating conveyor. The rollers transport the signature bundle until it is parallel to the stopper device in the direction of travel, at which point the required angle of direction is completely changed.

By lowering the coefficient of friction between the bundle of signatures and the transport conveyor than the coefficient of friction between paper and paper, the distance between the signatures of the bundle of signatures being conveyed does not shift, and the gap between the bottom surface of the stopper plate and the top surface of the table is reduced. This space prevents the paper on the bottom of the signature bundle from being damaged.

(Embodiment) An embodiment of the present invention shown in FIGS. 1 to 7 will be described in detail.

20a and 20b are unloading devices, 24 is a waiting conveyor, and 25 and 26 are right-angled transfer devices for handling the bundles of signatures P.
It can be transferred at right angles without changing the direction.

Reference numerals 27a to 27e are bundle direction converting devices which, when the long side of the signature bundle P is traveling perpendicular to the traveling direction, can change its direction by 90 degrees and make the short side perpendicular to the traveling direction. It is also possible to pass through a bundle of signatures that have already been diverted and bypassed through another route.

The wrapping machine 30c and the binding machine 31c are for fractional bundles, and the signature bundle P is carried into the packaging machine 30c with its short side perpendicular to the direction of travel.

FIG. 3 illustrates the right-angle transfer device 25. As shown in FIG.

33 is a short roller, 34 is a long roller, 35,
35 is a belt conveyor that can move the surface up and down.

The bundle of signatures P placed on the conveyors 35, 35 and advanced in the direction of the arrow 36 hits the stopper 37 and stops. At the same time, the stopper 37 moves to the stopper 37', and the conveyors 35, 35 stop and sink.

There, the signature bundle P is placed on the rollers 33, 34, and 33, advances to the left at right angles to the traveling direction, and is sent to the bundle direction changing device 27c.

The device 27c is a conveyor A for conveying bundles.
, a stopper device B, and a rotating transfer body C consisting of a belt or rollers.

Regarding conveyor A, 38 is a short roller. 39 is a long roller,
The coefficient of friction between the surface of each roller 38, 39 and the bottom surface of the signature bundle P is lower than the coefficient of friction between the signatures.

Each roller 38, 39 is fixed to the same shaft 41. (See Figure 4) 42 is a frame, 43 is a bearing, and the rotation of the motor 45 on the pedestal 44 is controlled by sprockets 46, chain 50, sprockets 48, 49, and chain 5.
1. Each roller 38, 39 via sprocket 47
is transmitted to.

Sprockets 52, 53, 54, and 55 (see FIG. 5) are intermediate sprockets.

Regarding the stopper device B, 58 is a stopper plate, which is attached to a lever 57 that rotates around a shaft 56.

A cylinder 59 is attached to the lower end of the lever 57 via a pin 62. 60 is the pin axis,
61 is a piston rod.

When the piston rod 61 is retracted, the lever 57 rotates clockwise and the stopper plate 58 tilts.
It occupies the position of the stopper plate 58'.

When the piston rod 61 is extended, the stopper plate 58' is in the solid line position. There is a slight space 6 between the bottom surface of the stopper plate 58 and the top surface of the table 40.
3 is maintained to prevent the paper sheet placed on the lower surface of the signature bundle P from entering the space 63 and damaging the paper sheet.

Numerals 64a and 64b are rod-shaped stoppers, and cylinders 65a and 65b are provided at the lower ends of the rod-shaped stoppers, and the urging force of the cylinders 65a and 65b causes them to protrude from the upper surface of the table 40 to the positions of the stoppers 64a' and 64b'.

The stopper 64a is longer than the stopper 64b, and this is to prevent the load from collapsing when the large and tall bundle of signatures P is blocked by the stopper 64a.

In FIGS. 3, 5, and 6, the rotary conveying body C is made of a belt or a roller, and the rotating conveying body C moves the signature bundle P forward slightly from the center of the bundle direction changing device load 7c. installed perpendicular to the direction.

Reference numeral 67 denotes a rotating shaft attached to the body, and the bifurcated bases of swinging arms 70, 70 are pivoted to this rotating shaft 67.

Reference numerals 68 and 68 indicate pulleys that are pivotally attached to the rotating shaft 67 within the bifurcated base of the swinging arm 70.

73, 73 are 2 formed at the tip of the swinging arm 70.
This is a bearing pulley attached to a pin 72 provided in the crotch-like part.

Reference numeral 75 denotes a belt guide attached to the upper part of the swinging arm 70 via a support 74. A belt 76 is stretched over the pulley 68 and the pulley 73 and guided by the belt guide 75.

The rotation of the motor 77 on the frame 44 is transmitted to the rotating shaft 67 via a sprocket 78, a chain 79, and a sprocket 69.

A cylinder 83 is attached between a bracket 81 provided at the bottom near the tip of the swinging arm 70 and a bracket 82 provided on the body. 84 and 85 are pins,
86 is a piston rod.

When the piston rod 86 is retracted, the pulley 73 occupies the position of the bracket 73', and at this time the belt 76
The upper surface of the belt 76 is lower than the surfaces of the rollers 38 and 39, and when the piston rod 86 extends, the belt 76 rises and becomes higher than the surfaces of the rollers 38 and 39.

Explain the action.

With reference to FIG. 7, counter stacker 22b
When the bundle of signatures P carried out from above reaches the waiting conveyor 24 with the short side perpendicular to the direction of travel, the belt conveyor 35 (see FIG. 3) of the right-angle transfer device 325 moves from the upper surface of each roller 33, 34. The stack of signatures p floats high and moves forward until it hits the stopper 37 and stops, and the stopper 37 reaches the stopper 37'.
Evacuate to. (This is so that the part of the paper laid under the signature bundle P that protrudes from the signature bundle P will not be damaged.) At the same time, the belt conveyor 35 also stops and sinks.

The bundle of signatures P moves to the left at right angles due to the rotation of the rollers 33, 34, and 33. Further, the bundle moves along the long sides of the rollers 38, 39, and 38 of the bundle direction changing device 27c in a state perpendicular to the traveling direction.

When the bundle of signatures P approaches the stopper 64a, the stopper 64a projects and occupies the position of the stopper 64a', and the stopper plate 58 occupies the position of the stopper plate 58 indicated by the solid line.

When the bundle of signatures P further advances, the left end of the bundle comes into contact with the stopper 64a and changes direction counterclockwise, resulting in the state of the bundle of signatures P ₂ in Figure 3 or Figure 7B, and is further folded. It becomes the state of book bundle P ₃ .

However, this direction transformation requires a transformation angle of 70 degrees of 90 degrees.
~80%.

At this time, the rollers 38 and 39 are temporarily stopped, and the swing arm 70 is swung so that the upper surface of the belt 76 is moved between the rollers 38 and 3.
9 and 38, and the stack of signatures P is placed thereon.

The signature bundle P moves toward the stopper plate 58 by the rotation of the belt 76 and comes into close contact with the stopper plate 58, resulting in the signature bundle _P4 shown in FIG. 7C.

Here, the direction of the signature bundle P is completely changed by 90 degrees. Then, the swinging arm 70 is lowered to its original position, and the rollers 38, 39, and 38 are rotated again, so that the signature bundle P moves forward and is carried into the packaging machine 30 from the right-angle transfer device 26.

When the bundle of signatures P is a small bundle, there is no paper sheet, so the stopper 64b is projected above the table 40 and set at the stopper 64b' position so that the bundle of signatures does not bite under the stopper plate 58.

When the bundle of signatures P is a large bundle, the direction can be changed by the transfer body using only the stopper plate 58 without the need for the stopper 64b to protrude above the table 40.

In the present invention, the belt 76 of the rotary transfer body C may be a single strip, or a driving roller or a group of rollers may be provided instead of the belt 76, and a floating belt may be used instead of the roller. Other suitable transport bodies for transferring and sinking back may be provided.

When the signature bundle P changes direction, the stopper 64a
However, in addition, the stack of signatures P is
By reducing the coefficient of friction between the signatures 8, 39, and 38, the signature bundle P is prevented from shifting between the signatures.

Next, for example, when the packaging machine 30a breaks down, the bundle of signatures P discharged from the counter stacker 22a
The bundle passes through the bundle direction changing devices 27b and 27c and is conveyed to the packaging machine 30b, but at this time, the stopper plate 58 is retracted to the position of the stopper plate 58', the stopper 64a is not protruded from the surface of the table 40, and the bundle is transported to the packaging machine 30b. The direction changing device 27c may have to frequently repeat changing the direction of the bundle of signatures P and passing the same bundle, but the position of the stopper plate 58 and the stopper 64a is changed by changing the position of the stopper plate 58' and the stopper 64a'. Since it is only necessary to move the stack to the opposite position or to the opposite position, the ability to transfer the bundle of signatures P will not be reduced.

In this case, the stopper 64b only needs to appear and retract in the same way as the stopper 64a, regardless of whether the bundle of signatures P is a small bundle or a large bundle.

(Effects of the invention) The present invention includes a conveyor configured so that the coefficient of friction between the paper and the conveyor is lower than the coefficient of friction between the paper and the paper, a stopper device that obstructs the progress of the bundle of signatures on one side, and A rotary transfer body is provided to raise the bundle of signatures from the conveyor, cut off contact with the transfer of the transport conveyor, and reliably restrict the final direction change of the bundle of signatures, and as the bundle of signatures advances, it After changing the direction of the paper by approximately 70 to 80% without damaging it, the rotating conveyor completely changes the direction by 90 degrees, so whether it is a large bundle or a small bundle, the angle is constant and there is no error. It will never occur.

The direction change angle can be corrected by the rotary transfer body smoothly and reliably without applying unnecessary impact to the bundle of signatures.

In addition, if it is necessary to frequently change the direction of the bundle and pass the bundle, it is only necessary to slightly change the position of the stopper device, and this operation can be performed instantly, so there is no reduction in the transfer capacity. Not at all.

Therefore, according to this apparatus, even if one of the plurality of packaging machines breaks down, the overall packaging capacity will not be reduced at all.
