[0002]
[Prior art]
2. Description of the Related Art Conventionally, a signature delivery device of a rotary press receives a signature folded by a folding mechanism of a folding machine by, for example, a delivery fan having four rows of impellers arranged at intervals in an axial direction. This is passed to a conveyor and discharged out of the machine.
[0003]
That is, the signature delivery device receives the signature 901 at the signature receiving portion of the rotating delivery fan 301 as shown schematically in FIG. 6 and moves (hereinafter, referred to as rotational movement) by the rotation of the delivery fan 301. The paper is conveyed by the signature receiving section, delivered to the conveyor at a uniform pitch in a scale-like manner and overlapped, and discharged out of the machine as a signature row.
[0004]
In this series of flows, the signature 901 received by the signature receiving section and transported by rotation of the delivery fan (hereinafter referred to as “rotational transport”) is, for example, the leading edge of the signature by the blade member of the delivery fan 301. End of the signature (hereinafter referred to as the trailing end of the signature) that tends to hang from the tip of the blade member.
[0005]
Therefore, in order to guide the trailing end of the signature so as not to hang down, the signature is provided so as to be adjacent to the outer periphery of the rotation area of the delivery fan 301 at a wide interval in the width direction of the signature. An signature guide device having a book guide member (hereinafter referred to as signature rear guide) 401 is provided. Then, as shown in FIG. 6, the lateral end of the signature 901 in the width direction protrudes from the side end of the signature rear part guide 401 provided on the outermost side.
[0006]
As a conventional technique of the signature guide device as described above, there are, for example, those disclosed in Patent Literature 1, Patent Literature 2, and Patent Literature 3.
[0007]

[Problems to be solved by the invention]
In recent years, the speed of rotary presses has been remarkably increased. For example, in a newspaper rotary press in Japan, a print speed of about 140,000 copies per hour was conventionally used, but recently, a print speed of about 180,000 copies per hour has been achieved. It has come to be. Accordingly, the delivery fan releases the signatures released from the folding mechanism of the folding machine one after another at a faster printing speed, which is approximately 30% higher than before, so the delivery fan releases the signatures one after another. The signatures must be rotated synchronously to receive the signatures, and the signatures received by the signature receiving unit must be sequentially rotated and conveyed at high speed.
[0012]
As the speed of the rotary press increases, the rotation of the delivery fan causes a rapid air flow spiraling outward in the rotation direction of the delivery fan around the rotating delivery fan. The trailing end of the broken signature is rapidly swollen by the above-described fast air flow, and rapidly flutters so as to protrude outside the delivery fan.
[0013]
As described above, in the folding machine of the rotary press that performs high-speed printing, the signature guide devices described in Patent Documents 1 to 3 have a common problem to be solved.
[0014]
That is, as shown in FIG. 6, the rotating delivery fan rotates and moves while receiving the first signature 901a released from the folding roller at the first signature receiving portion, and performs the first folding. A second signature receiving unit following the book receiving unit receives the second signature 901b that has been released next.
[0015]
In receiving and rotating the signature, the trailing end of the first signature 901a is rapidly moved by the fast air flow generated around the delivery fan rotating at high speed in synchronization with the rotary press. It is pushed out of the delivery fan, and is pushed so as to rapidly flow on the signature guide surface of the signature guide rear guide. The rear end of the signature has no rigidity on the side of the paper cut by the so-called folding mechanism, and is folded into a part of the interval between the signature rear guides 401 provided with a plurality of intervals so as to undulate and wrinkle. Resulting in.
[0016]
The trailing end of the signature that undulates into the gap increases frictional resistance against the signature rear guide and becomes less slippery. As the paper slips off from the bottom of the signature receiving section, the balance between the left and right of the signature being conveyed in rotation is lost or the rotation and conveyance of the signature are delayed.
[0017]
For example, in newspaper printing, a so-called thin page signature of 4 to 8 pages on broad paper or a signature page of 8 to 16 pages of tabloid paper (4 to 8 pages in terms of broad paper) is particularly used. The signature itself is lighter and less rigid than a thick and heavy signature signature. In other words, the rear end of the origami that is also on the back side is extremely poor in rigidity and is damp, so the rear end of the origami that protrudes from the tip of the wing member of the origami receiving part at the interval is As shown in FIG. 6, the rear guides are easily deformed by being entangled in the space between the rear guides, and are likely to be wrinkled due to a wavy shape. In addition, since both sides in the width direction of the signature are off from the signature rear guide, the side edge near the rear end of the signature is deformed so as to be bent outward, so-called ear folding. Cheap.
[0018]
Therefore, as described above, the signature received by the signature receiving unit slips from the bottom surface of the signature receiving unit during rotation and transport, and loses or delays the left and right balance. Or, the leading end of the next signature may interfere with the trailing end of the delayed signature, so that the signature being rotated and transported is likely to cause a paper jam between the delivery fan and the signature guide surface. In addition, when the signatures with the distorted posture are passed on the conveyor, the edge portion of the signatures may be broken, or the signatures may be arranged diagonally as shown in FIG. There was a problem that it would not line up. This impairs the quality of signatures, hinders speeding up of the rotary press, and cannot improve productivity.
[0019]
The present invention can solve the problems of the above-described conventional technology at once, and even when a rotary press is operated and high-speed printing is performed, the signature can be deformed in a wavy shape in the width direction or the ear can be broken. It is another object of the present invention to provide a signature guide device for a folding machine which can be discharged out of the machine in an orderly signature row without disturbing or delaying the right and left balance.
[0020]
[Means for Solving the Problems]
To achieve the above object, a signature guide device according to the present invention receives a signature folded by a folding mechanism of a rotary press at a signature receiving section of a delivery fan, and conveys the conveyor by rotation of the delivery fan. In a signature guide device of a folding machine that guides an end of a signature that cannot be accommodated in a delivery fan when transported upward, the two sides having at least the same width as the signature and substantially parallel to the width direction. One side is located below the vicinity of the folding mechanism, the other side is located above the vicinity of the conveyor conveyance surface, and the portion from the one side to the other side is an origami guide surface in an arc shape near the rotation area of the delivery fan. A guide member is provided along the side of the signature to guide the end of the signature, which is conveyed by the rotation of the delivery fan, over the entire width of the signature.
[0021]
In the signature guide device having the above-described configuration, the guide member is supported by the moving means, and the guide member is provided so as to approach or separate from the rotation area of the delivery fan via the moving means. The member has a ventilation hole over the entire surface of the signature guide surface, and the guide member is constituted by at least two guide members that can be divided in the middle of the signature guide surface having an arc shape. At least one of the guide members is detachably provided.
[0022]
[Operation]
The signature folded by the folding mechanism of the rotary press is received by the signature receiving part of the rotating delivery fan, and is sequentially rotated and conveyed onto a conveyor positioned below the delivery fan. At this time, the end of the signature that does not fit into the delivery fan is guided by the signature guide surface of the guide member of the signature guide device over the entire width thereof.
[0023]
The signature guide surface of the guide member is moved toward or away from the rotation area of the delivery fan by the operation of the moving means supporting the guide member. In addition, around the rotating delivery fan, a high-speed air flow spiraling outward in the rotation direction is generated, and the air flow generated by the rotation of the delivery fan and the signature of the signature raised by the air are generated. The air between the end and the signature guide surface quickly escapes to the outside through the ventilation hole provided over the entire signature guide surface, and the side edge of the signature end quickly reaches the signature guide surface. However, the free movement of the end can be suppressed very quickly. Further, one of the at least two guide members constituting the guide member can be attached and detached, and by detaching the guide member, maintenance of the delivery fan and the like becomes easier.

[0038]
Next, the operation of the above-described embodiment of the signature guide device according to the present invention will be described with reference to FIGS.
[0039]
The signature guide surface 41 of the signature rear guide 4 supported by the moving means 5 is set so as to approach a position appropriately separated from the outer periphery of the rotation area of the delivery fan 3 by extension of the cylinder rod of the pneumatic cylinder 54. (See FIG. 1). Then, the rotary press is operated, leading to high-speed printing.
[0040]
The printing paper C carried and cut by the folding cylinder 7 is folded by the folding mechanism 1. That is, the folded portion of the printing paper C is inserted between the folding rollers 12, 12 by the blade 11 entering the gap between the pair of folding rollers 12, 12, in synchronization with the rotation phase of the folding cylinder 7. 4a).
[0041]
The printing paper C folded into two by the pair of folding rollers 12, 12 is discharged at a high speed downward as a first signature 9a. The first signature 9 a is guided toward the outer periphery of the delivery fan 3 by the first guide 21 and the second guide 22. The delivery fan 3 rotating in synchronization with the rotation phase of the folding cylinder 7 transfers the first signature 9a guided by the first guide 21 and the second guide 22 to the first signature receiving unit 35a. Catch at the bottom of At this time, the leading end of the first signature 9a reaches the bottom of the first signature receiving portion 35a, and in this state, up to about half of the back surface of the first signature 9a is moved by the impeller 32. Is supported by the first blade member 34a, and the remaining portion is separated from the tip of the first blade member 34a and is rotated and conveyed at high speed (see FIGS. 4B and 4C).
[0042]
At the time of this rotary conveyance, the rear end portion 91a of the first signature 9a is rapidly swirled by a rapid flow of air that is generated around the rotating delivery fan 3 and spirals outward in the rotating direction, and The signature guide surface 41 provided wider than the width of the signature 9 simultaneously and promptly over the entire width reliably receives the signature along the surface (see FIG. 4D). As a result, the signature 9 does not wrinkle due to a wavy deformation in the width direction, and does not deform so that each side edge is curved outward and bends and bends.
[0043]
Further, when the first signature 9a is rotated and conveyed by the first signature receiving portion 35a, the rear end portion 91a of the signature 9 becomes wrinkled or curved outward as described above. Without being guided by the signature guide surface 41 and moving, the rear end portion 91a of the signature 9a is moved without receiving a braking action on the signature guide surface 41, and the signature 9a is moved. It slips up from the bottom of the receiving section 35a and does not break the left and right balance of the rotationally conveyed signature and does not delay the rotational conveyance, and the rear end portion 91a of the signature 9a is securely connected to the signature guide surface 41. And is conveyed in rotation with the rotation of the delivery fan 3 (see FIG. 4E).
[0044]
As shown in FIGS. 3 and 5, in the signature guide surface 41 provided with a large number of ventilation holes 42, the rear end portion 91 of the signature 9 and the signature guide surface 41, which are rapidly pushed up by the air flow. And the air spirally flowing outward toward the periphery of the rear end portion 91 swiftly and outwardly from the large number of air holes 42. Therefore, the side edge of the rear end portion 91 quickly reaches the signature guide surface 41, and the free movement of the rear end portion is rapidly suppressed, and the guiding action by the signature guide surface 41 can be more reliably and effectively obtained. .
[0045]
Similarly to the first signature 9a, the second signature 9b received by the second signature receiving portion 35b and the signature 9 sequentially discharged from the folding mechanism 1 are also used. The rear end portion 91 is received along the signature guide surface 41 over the entire width of the rear end portion 91, and is conveyed one after another as the delivery fan 3 rotates (see FIG. 4F).
[0046]
The signature 9 transported by the rotation of the delivery fan 3 so as to approach above the conveyor 8 is transferred from the signature receiving portion 35 onto the running conveyor 8 and is scaled at a uniform pitch without being disturbed. It is shifted and discharged outside the machine.
[0047]
【The invention's effect】
As described above, the following effects can be obtained by implementing the present invention.
[0048]
In other words, even when the rotary press is operated and high-speed printing is performed, the signature is formed by the signature guide surface provided at the rear end of the signature simultaneously and quickly over the entire width and wider than the signature width. So that the signature that is rotated and conveyed by the delivery fan can be wavy in the width direction and wrinkled, or each side edge of the rear end bends outward. There is no such thing as being deformed, bent, and broken.
[0049]
Furthermore, the signature did not slip off from the bottom of the signature reception unit during rotation conveyance and did not lose or delay the left-right balance, and was therefore released from the folding roller and received by the signature reception unit. The signature can be reliably rotated and conveyed along the signature guide surface, and can be transferred onto the conveyor so as to be shifted at equal pitches and overlapped, so that a regular signature row can be discharged out of the machine.
[0050]
According to the second aspect of the present invention, since the guide member is supported by the moving means and is provided so that the signature guide surface thereof can approach or separate from the rotation area of the delivery fan, the signature can be saved. (1) Even if a paper jam occurs between the delivery fan and the signature guide surface, immediately separate the signature rear guide away from the outer periphery of the delivery fan to remove the paper jam and damage the signature ejection device. It can be easily restored without causing any recovery.
[0051]
According to the third aspect of the present invention, in the signature guide surface provided with the ventilation hole, a rapid air flow spiraling outward in the rotating direction generated around the rotating delivery fan is provided. The air between the trailing edge and the signature guide surface, which is rapidly pushed up by the flow of air, quickly escapes to the outside through the ventilation holes provided on the signature guide surface, so that the trailing edge of the signature The side edge of the portion quickly reaches the signature guide surface, and the free movement of the rear end portion is quickly suppressed, so that the guidance action by the signature guide surface can be obtained more reliably and effectively.
[0052]
Further, according to the invention according to claim 4, the signature rear guide is constituted by at least two guide members that can be divided in the middle of the circular signature guide surface, and at least one of the guide members is detachably provided. By removing this, maintenance around the delivery fan becomes extremely easy, and the maintenance of the delivery fan and its surroundings can be thoroughly maintained. It became so.
[0053]
From these facts, the ripples at the trailing end of the signature and the edge breaks at the spatula, which were one of the factors that hindered the speeding up of the conventional rotary press, were eliminated, and the signatures were not disturbed or jammed. In this way, a stack of signatures that overlap each other can be formed on a conveyor and discharged out of the machine. As a result, the speed of the rotary press can be increased without impairing the quality of the signature, and the productivity can be improved.
