DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an obstruction for counting signatures (for example, newspapers) conveyed in a line at a constant overlapping pitch by a conveyor, and obstructing the signatures into a predetermined number of copies. And a branching means for selectively branching a predetermined number of copies to separate downstream conveyors in the transport direction.

[0002]

2. Description of the Related Art Signatures conveyed in a row at a constant overlapping pitch on a conveyor are counted and classified into a predetermined standard number (hereinafter, referred to as a constant) or a number of non-constant copies (hereinafter, referred to as a fraction). And, with respect to the conventional technology of distributing a predetermined number of signature sheets to each of the conveyors branched downstream thereof and switching and conveying the conveyors,
For example, Japanese Utility Model Publication No. 55-17725 and Japanese Unexamined Patent Publication No.
There is one disclosed in Japanese Patent Application Laid-Open No. 117562.

[0003] Japanese Unexamined Utility Model Publication No. 55-17725 (Prior Art 1) discloses that a signature row (printed material) conveyed at a constant overlapping pitch is counted at a counting position on a conveyor, and the counted value is calculated. A closing member (blocking dividing plate) for closing and separating the signature row based on the above, and provided above the downstream end of the conveyor on the upstream side in the transport direction for transporting the signatures counted at the counting position. In addition, the guide sheet (paper guide member) of the signature provided immediately before the blocking member and the signature row passing between the guide plate and the downstream end of the conveyor on the upstream side in the transport direction are interrupted. And a branching member that changes the transport path of the signature row (separating plate that converts the transport path), and the signature row conveyed from the conveyor on the upstream side in the transport direction is not forcibly transported, and the branching member is Branches downstream in the transport direction of Is configured to be guided to one of the conveyor of the conveyor are.

[0004] The signature row after counting is leveled by a guide plate, and leans from the downstream end of the conveyor on the upstream side in the transport direction, so that the conveyor forming the working position of each of the leading edges is bent. Enter the descending ramp. The blocking member waiting behind the guide plate is moved and blocked by the pneumatic cylinder toward the operation position, or the branch member is angularly displaced by the pneumatic cylinder,
The leading edge is inserted into the position of operation of the signature sheet row to change the transport path of the signature row.

Japanese Unexamined Patent Publication (Kokai) No. 2-117562 (prior art 2) discloses a signature (conveyed) that is conveyed so as to cope with a case where the conveying speed is higher than that of the conventional art 1. (Conveyed material) at the counting position on the conveyor, and closing means for closing and dividing the signatures based on the counted value is provided from each downstream end of the conveyor which is divided into two so as to be continuous. A closing means (first sorting device) and a second closing device (second sorting device) are provided on the transport path of the signature row forming the action position as if to embark,
Guide plates are provided on the upstream side in the transport direction in the same manner as in the prior art 1, and the blocking members (first and second partition plates) of the respective blocking means are appropriately operated to perform the blocking partitioning. It has become. The signature row conveyed from the two separate conveyors is conveyed without being forcibly conveyed.

A branching means (third sorting device) for changing the transport path of the signature row, downstream of the second closing means in the transport direction.
A branch member (segment plate) is inserted into a signature row passing between the guide plate and the downstream end of the conveyor on the upstream side in the transport direction of the second closing means, or returns to the standby position. By doing so, the signature row is configured to be guided to any one of the conveyors branching on the downstream side in the transport direction of the branching member. The guide plate of the signature row is used to prevent the subsequent signature row from being disturbed when each closing member is operated.

In order to guide the signature row to any one of the branched conveyors, for example, the number of signatures counted based on the count value is set as the sum of a constant and two types of fractions. In the blocking means (third partition plate),
Blocking of the set number of copies is performed, and in the branching unit (third sorting device), when the boundary between the constant number and the first fraction passes through the branching unit, the tip side of the branching member performs angular displacement operation. The first fraction is switched to the upper conveyor, and the second blocking means (the second sorting device) performs the second closing when the boundary between the first fraction and the second fraction passes through the second blocking means. The two fractions are closed and the branching member (third partition plate) is returned over the gap generated in the transport signature row, and again the original transport path,
That is, the conveyor is switched to the lower conveyor (first downstream transport path), and the second fraction is transported after the preceding constant.

When the second closing member (second partitioning plate) is operated to close the signature row, the lower conveyor (first downstream side transport path) has a normal conveying speed only for the lower conveyor. Switched to be driven at a higher speed,
When the second blocking member (the second partition plate) returns, the speed is switched to the original constant speed.

[0009]

In the prior art 1, the signature row is conveyed through the counting position on the conveyor, and the upper surface of the signature row is leveled by the guide plate, and the upstream of the conveyor in the transport direction is conveyed. Reach the end. Further, while being pressed by the guide plate from the end to the upper surface, the guide plate enters a space from the end to a downstream conveyor in the conveying direction, which is a downstream side of the conveyor, that is, a so-called conveyor bent and descending inclined portion. Here, each of the conveyed signatures is overhanged in the air from the roller at the end of the conveyor on the upstream side in the conveyance direction, and the leading portion of the origami wraps around the downstream conveyor while hanging down in a curved manner.

[0010] The degree of the droop varies depending on the so-called waist of the signature, and also depends on the conveyance speed of the signature. In the prior art 1, since the signature row conveyed in the form of drawing this curve is hung or branched at the curved and hung portion, the signature row is divided by the blocking member and the branch member. In addition, there is a problem that the operation position at the time of branching is not determined, the number of copies in the divided bundle increases or decreases, and the number of copies in the divided bundle becomes inaccurate (problem 1).

Also, since the signature row after the counting is simply carried on a conveyor and conveyed with the upper surface of the signature row open, the signature easily slips on the conveyor, and the signature easily shifts. In addition, since the guide plate, which is an obstacle to the signature, hinders accurate conveyance of the signature, for a predetermined number of copies,
There is a problem (problem 2) that the number of copies in the block that is divided into blockages tends to increase or decrease.

Further, when the leading edge of the closing member moves to the operation position to close the signature row, the signature that must be conveyed downstream without being blocked is transported by the leading edge. There is a problem (problem 3) that the paper is pressed against the roller at the end of the conveyor on the upstream side in the direction with a strong force, and the conveyance is hindered.

On the other hand, when the closing member closes the signature row, an interval is provided between the closing member and the end of the downstream signature row, and the blocking member returns after a predetermined time. When the top is leveled to pass between the roller at the end of the conveyor and the guide plate on the upstream side in the transport direction, the brake is applied, There is a problem (issue 4) that the signature row is disturbed.

Further, when the branch member interrupts the signature row and the signature row is changed in path and is conveyed, similarly to the problem 2, the signature is easily slipped with respect to the conveyor, and the signature is easily shifted. In addition, when the surface of the signature row contacts the guide plate and tries to pass through between the roller at the end of the conveyor on the upstream side in the transport direction, the transport of the deposit row is hindered. Further, the signature row whose path has been changed by the branching member is transported to the downstream conveyor using the branching member as a crossing board,
Again, the signature row is braked by the frictional force with the branch member. For this reason, there is a problem (problem 5) that the signature row is not faithfully conveyed by the conveyor, and paper jams frequently occur in this portion.

In the prior art 2, as described above, the guide plate, the closing member and the branching member for the roller at the end of the conveyor on the upstream side in the transport direction are used when the signature row is closed and divided and when the branch is branched. The relation between the members is substantially the same as that of the prior art 1, and the prior art 2 has the same problems as the problems of the prior art 1 (problems 1 to 5). In order to process a constant and two types of fractions, two blocking members are provided separately in the transport direction, so that the conveyor becomes long and the installation space is widened (problem 6). is there.

Further, one of the two closing members is provided on the downstream side of the conveyor in the conveying direction,
The distance that the signature is transported to the closing action position after counting becomes longer, during which the signature is slippery with respect to the conveyor,
Since the sheet is conveyed in a state where it is easily shifted, there is a problem (block 7) that the blocking section is likely to be inaccurate as the speed of the rotary press increases, and it is not possible to cope with high speed.

The present invention solves the problems of the prior art as described above at once, and ensures that the signature row is securely transported without disturbance, is securely closed without disturbance, and is reliably prevented. A relatively small and low-cost transport signature row that can be reliably branched and reliably transported to the downstream without disturbance, and that small numbers of fractions can be blocked and processed during high-speed printing. It is an object of the present invention to provide a branch transport device.

In the branch transport apparatus 1 in the second embodiment, the bases 80, 80 in the case of the closing means 10 of the first embodiment are used.
Instead of the bracket 86 in the framework of the brackets 85 and 86, a bracket 87 is attached to the upper ends of the bases 80 and 80 as shown in FIG. Provided. In this framework, a second blocking means 30 is provided in addition to the first blocking means 10 which is the same as the blocking means 10 of the first embodiment.

This is a description of an example in which a constant D separated from the row B is transported to the third conveyor 43. Since the conveyor section 40 is operated in synchronization with the rotary press at the same speed as described above, the signature row B is not affected by the operation speed, and is surely in a stable state without being disturbed. It is to be conveyed by.

In the description of the operation, the transporting distance of the predetermined number of signatures A counted by the counting device 3 is determined by the number of pulses output from a rotary encoder (not shown) interlocked with the conveyor 40. ,
Based on the count completion signal of the signature A output from the counting device 3,
It is calculated by the control means S (see FIG. 1). The control signal (not shown) output as a result activates the pneumatic cylinder 11 of the closing means 10 to control the closing step. Further, the pneumatic cylinder 21 of the branching means 20 is operated, and the branching process of the signature row B is controlled. Note that a detailed description of these control systems is not a main part of the present invention, and thus will be omitted as described above.

FIG. 7 shows that the constant D1 blocked and divided by the blocking means 10 is stored in the third conveyor 4 in the lower stage.
3 and the leading part of the signature row B of the next constant D2 is forcibly transported by the first forcible transporting means 50 and the signature of the preceding constant D1 is transferred. This shows a state in which A1 is introduced into the third conveyor at an interval P1 from the end of A1.

The preceding constant D1 is the third conveyor 43
Is deposited by the deposition processing device 4 downstream of. The pressing roller 58 of the first forced conveying means 50 can change the interval with the drive roller 421 while pressing the signature row B according to the thickness of the signature row B. FIG. 8 shows a state in which the branching member 22 of the branching means 20 is inserted between the last signature A2 of the constant D2 following the interval P1 and the leading signature A3 of the fraction C following the constant D2. Is shown.

For example, when the number of copies reaches a predetermined number, a count completion signal is output, and the subsequent signature row B is branched to the fourth conveyor 44 side, the last signature A2 of the constant D2 is When transported to the branching position Z, the rod of the pneumatic cylinder (branch drive member) 21 of the branching means 20 operates so as to retract, and the arm 24 (FIGS. 2 and 3).
The branching member 22 is angularly displaced about the shaft 23 through the branching member 25, and the branching action portion 25 is lowered on the signature A and inserted between the signature C and the subsequent signature A3 of the fraction C so as to be divided. Is done.

The signature A3 at the head of the fraction C is
The first forcibly transporting means 5
2nd conveyor 4
2 is forcibly conveyed in such a manner as to go straight in substantially parallel to the conveying surface of No. 2 and is a branching position Z where the signature row B is branched.
However, it is always kept stable.

The operation of the branch means 20 is performed by the branch member 22.
Is angularly displaced from the standby position to the operating position 29, and is inserted between the signatures A2 and A3 of the signature row B at the branching position Z on the way. The subsequent signature A3 of the fraction C is exactly the fourth conveyor 44 in the upper stage.
Indicates a state that is about to branch to.

The preceding constant D 2 and the subsequent signature row B to be a fraction C are separated by the branching member 22 inserted into the signature row B. The preceding constant D2 is conveyed downstream by the third conveyor 43, and the succeeding fraction C is forcibly sent out by the first forcible conveying means 50, and the second forcible conveyance is performed along the upper surface of the branch member 22. It is conveyed toward the opposing part of the roller 61 and the pressing roller 62 of the means 60.

FIG. 9 shows that one of the preceding constants D2 is deposited by the deposition processing device 4 downstream of the third conveyor 43 by the branching operation of the branching member 22, and the other is that the signature row B is deposited by the fourth conveyor 44 on the other side. The driving roller 421 of the first forced conveying means 50 and the opposing portion of the pressing roller 58, that is, the downstream end of the forced conveying section of the first forced conveying means 50 and the roller 61 and the pressing roller 62 of the second forced conveying means 60 This indicates a state in which the last signature A5 with a fraction C is reliably transported by the forced transport action of the opposing portion of the second transport section, that is, the upstream end of the forced transport section of the second forced transport means 60.

In the process, the last signature A of the fraction C while the fourth conveyor 44 is being conveyed reaches the closing operation position Y below the closing means 10, and the pneumatic cylinder (the closing The rod of the driving member 11 is extended,
This shows a state in which the closing member 12 has moved to the operating position 14 and the closing action portion 13 of the closing means 10 has closed the preceding signature A4 having the constant D3.

The driving roller 42 of the first forced conveying means 50
Since the distance between the opposing portion of the first and pressing rollers 58 and the opposing portion of the rollers 61 and 62 of the second forced conveying means 60 is set to be equal to or less than the length of one signature sheet in the conveying direction, The fraction C can be reliably conveyed and branched.

FIG. 10 shows that the last signature A5 of the fraction C conveyed by the fourth conveyor 44 reaches, for example, the opposing portion between the roller 61 and the pressing roller 62 of the second forcible conveying means 60, and the subsequent constants. When the interval P2 is opened from the blocking action position Y that blocks D3, the branch action portion 25 of the branch member 22 returns to the standby position across the space of the interval P2, and the preceding fraction C is , Fourth conveyor 44
Shows the state of being conveyed by.

This interval P2 is an appropriate interval necessary for the branching action portion 25 of the branching member 22 to return, and the number of pulses (another detection method of the interval P2 is a photoelectric device or a timer). , The pneumatic cylinder 21 operates and the rod extends. As a result, the branching action unit 25 returns to the standby position, and the closing member 12 also returns to the standby position. The constant D3 of the subsequent signature row B that has been blocked is passed through the first forced conveyance unit 50. It is forcibly started to be conveyed to the third conveyor 43 without delay.

As described above, the constants DD2 and D3 of the number of copies predetermined by the control device (not shown)
The fraction C is conveyed to the conveyor 43, and is conveyed to the fourth conveyor 44, where it is processed by the deposition processing device 4 or the like connected downstream. It should be noted that the branch path of the fraction C or the constant D that is blocked, divided, and branched is not limited to either the third conveyor 43 or the fourth conveyor 44, respectively. It is needless to say that control can be performed so as to be selectively conveyed to the four conveyors 44.

As described above, in the operation of the branch transfer device 1 described above, the third transfer mechanism provided on the shaft 23 supporting the roller 61 is used.
Rollers 436, 436... For the conveyor 43
Even if the roller 61 has a small diameter with respect to the rollers 61, 61.
The conveyance of the signature row B passing through the opposed portions of the zero roller 61 and the pressing roller 62 is not hindered.

The forked signature row B is formed by the driving roller 421 and the pressing roller 58 of the first forced conveying means 50.
Is passed to the second compulsory transporting means 60 downstream of the facing portion immediately after passing through or passing through the facing portion of the signature sheet A.
Is forcibly transported to the fourth conveyor 44 without fail.

Next, the operation of the branch transfer device 1 according to the second embodiment of the present invention will be described. The first closing means 10 which is the same as the closing means 10 of the first embodiment acts to close the signature row B in the same manner as the closing means 10 of the first embodiment. Based on the control signal from the control means S (see FIG. 1), the closing function of the signature row B similar to the first closing means 10 is performed separately from the first closing means 10.

That is, the rod is extended by the operation of the second pneumatic cylinder 31 based on the control signal from the control means S (see FIG. 1), the second closing member 32 is moved to the operating position 34, and the signature row is changed. It separates back and forth to block the progress of the subsequent signature row, and similarly, by shortening the rod, the second blocking member 32
Retreats upward from the operating position 34 and allows the subsequent signature row to proceed.

The closing operation is the same as that of the first closing means 10 because the second closing surfaces 37 are substantially the same as the first closing surface 17. When at least one of the first closing member 12 and the second closing member 32 is at the operating position 14 (34),
The other is in the retracted position.

When the transport speed of the signature row B is high and when the signature A of the signature row B is separated and branched and transported by one or a small number of copies, the signature row B and the transported signature row B at high speed are separated. The time required for one or a small portion of the signature A to pass through the closing operation position Y is short, that is, shorter than the time required for the closing means 10 to move up and down with respect to the operating position 14 of the closing member 10. Therefore,
The blocking action of only the single blocking means 10 as in the first embodiment will not be in time.

Therefore, as in the second embodiment, a plurality of closing means, that is, the first closing means 10 and the second closing means 30 are provided side by side, and the signature row B and one copy which are conveyed at high speed are provided. Or to separate and transport a small portion of the signature A,
Immediately after the one closing member is raised, the other closing member is lowered to the operating position 14 (34), so that the signature sheet B conveyed at high speed and one or a small part of the signature sheet A are blocked. The blocking action is performed in response to the short time passing through the action position Y.
