Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blocking and sorting device that counts and sorts into a predetermined number of signatures (for example, newspaper) that are conveyed in a row at a constant overlapping pitch by a conveyor.

[0002]

2. Description of the Related Art Conventionally, the number of signatures conveyed in a line on a conveyor at a constant overlapping pitch is counted, and a predetermined standard number (hereinafter referred to as "constant") or a number other than a constant (hereinafter referred to as a fraction). For example, the techniques disclosed in JP-A-60-93059 (Prior Art 1) and JP-A-2-117562 (Prior Art 2) are known.

The technique described in the prior art 1 is a counting device for dividing a conveyor that conveys a series of signatures at a constant overlapping pitch into an upstream conveyor and a downstream conveyor, and counting the number of signatures passing through on the upstream conveyor. And a partition plate (first blocking member) to be inserted based on the numerical value between the signatures conveyed in a row, and the re-sorting plate for fractional classification on the boundary between the upstream conveyor and the downstream conveyor. (Second blocking member) is provided so that the relative speed of the downstream conveyor can be changed with respect to the upstream conveyor, and the transport speed of the downstream conveyor is set to be higher than that of the upstream conveyor in conjunction with the blocking operation timing of the second blocking member. Is also provided with a speed change means. As a result, fractional signatures are classified together with the fixed classification of signatures.

That is, when dividing a fixed number of signatures,
Only the first blocking member operates, and the second blocking member provided downstream thereof does not operate. Then, when dividing a signature with a fraction less than the constant, the first blocking member is activated to perform division so as to make a bundle with a signature with a fraction less than the constant, and then the determined constant. The second blocking member actuates and divides the fractional portion following the portion, and the downstream conveyor is switched at high speed. The leading part of the signature line is fast-forwarded and conveyed to the deposition processing apparatus.

After a lapse of the depositable time, the second blocking member returns to the standby position and the downstream conveyor returns to the original speed. In addition, the first blocking member blocks the subsequent signature row for a time period in which the fractional part can be deposited by the deposition processing device, and then returns to the standby position.

Next, the one described in the prior art 2 is composed of an upstream conveyor and a downstream conveyor branched into a plurality, and a counting device is provided on the upstream conveyor to count the number of signatures passing through and to convey and move. The quantity is measured, and the signature line is sorted by appropriately operating the first sorting device (first blocking member) and the second sorting device (second blocking member) that are sequentially provided at intervals on the upstream conveyor. To do.
Particularly, regarding the first blocking member and the second blocking member for depositing a signature of a constant and a fraction by a depositing apparatus connected to the end of the conveyor, the partition plate (first blocking member) described in Prior Art 1 is used. (Stopping member) and re-partitioning plate (second blocking member) are similar in configuration and operation, and the signature line to be conveyed is
It is designed to be divided into a constant and a fraction.

That is, in the case of the fractional division, the predetermined number of copies is divided into a predetermined number of copies by the first blocking member like a constant division as a sum of a constant and one fraction. The timing at which the boundary between the constant number and the fraction passes through the second blocking member is determined from the transport movement amount of the signature that is transported after being further divided, and the boundary passes through the second blocking member. At this time, the second blocking member is activated and the transport speed of the downstream conveyor is switched to a high speed, and is divided into a constant amount in the first half and a fractional amount in the second half.

The constant number of signatures to be conveyed is conveyed downstream at a high speed, and after the required time, the second blocking member returns and the conveyance speed of the second conveyor also returns to the fractional number of signatures to be conveyed. And are to be conveyed sequentially downstream with a required interval.

[0009]

According to the prior art 1 and the prior art 2, the first blocking member (the partition plate, the partition plate, which is spaced apart in the transport direction of the signature row toward the downstream side of the conveyor).
The first partitioning device) and the second blocking member (re-partitioning plate, second partitioning device) are sequentially arranged, and a constant blocking value is blocked by the first blocking member, and a fraction less than the constant is locked by the second blocking member. I try to stop it. That is, the signatures of which the counting device has counted a predetermined number of copies as a constant or a fraction, the transport movement amount from the counting device to the downstream is measured by an appropriate means, and reaches the blocking position of each blocking member. If so, the blocking members are activated in order to divide the signature row into the number of copies.

Therefore, as the distance from the counting device to the blocking position becomes longer, and as the printing speed becomes faster, the moving amount of the conveyor belt becomes larger.
The difference with the movement amount of the signatures that are conveyed while slipping behind the conveyor belt tends to increase. As a result, the difference between the actual amount of travel of the signature and the amount of transport movement to be weighed becomes large, making it difficult to classify into the correct number of copies as the distance from the counting device to the blocking position increases.
In particular, with the second blocking member arranged downstream of the first blocking member, it becomes more difficult to accurately divide the number of copies, and there is a problem that the classification accuracy is significantly reduced and the number of copies is excessive or insufficient.

Further, since the distance relationship between the blocking action portion of the blocking member and the transported signatures changes depending on the change in the thickness of the signatures, the blocking action of the blocking members on the signature row is effected. Since the timing of is substantially changed, the classification accuracy is reduced. Furthermore, the top of the signature that is supposed to precede without being blocked by the signature that is blocked is pushed by the blocking action part to block the subsequent signature, so the preceding signature is There was a problem that it disturbed and hindered transportation.

On the other hand, while the second blocking member is operating to block the fraction, simultaneously with the operation of the second blocking member, the downstream conveyor is driven fast forward, and the signature line is dragged from the low speed side to the high speed side. In this way, we are fast-forwarding a fixed number of signatures, and are trying to expand the gap between the latter half and the fraction side. As a result, the higher the printing speed, the higher the conveyor speed, and the more likely the fast-forwarding constant-side signature row is disturbed. Therefore, there is a problem that the constant side and the fraction side are extremely unstable, and the jammed line in the downstream stacking processing device is likely to occur due to the disorder of the signature array.

Further, due to these problems, in the stacking processing apparatus connected to the end of the conveyor, the number of stacking sections to be processed becomes inaccurate, which is excessive or insufficient. There was a problem that it caused a great deal of trouble to the store and readers.

Furthermore, the first blocking member and the second blocking member are arranged at intervals in the conveying direction of the conveyor, and the downstream conveyor is fast-forwarded when the fraction is blocked. Therefore, there is a problem that the path of the conveyor becomes long, the control structure becomes complicated and the size becomes large, and the cost increases.

In addition, since the overlapping pitch of the signature rows that are conveyed while being shifted and overlapped by the fast-forwarding is widened, the printing surfaces of the signatures are rubbed against each other to cause stains, and there is a problem that the print quality is deteriorated. It was

[Means for Solving the Problems] In order to solve the above-mentioned problems, a conveyor for conveying a signature line and a signature forcibly conveyed by being sandwiched from above and below in a line with a certain overlapping pitch on the conveyor. Is provided in a counting sorting and conveying device having a counting device for counting the number of sheets in the course of transportation and a blocking and sorting device for sorting the signature line on the conveyor into a predetermined number of copies based on the count value on the downstream side of the counting device. In the blocking segmentation device, two series of blocking members, a first blocking member and a second blocking member, a blocking moving means for moving the two blocking members, and a blocking position are passed. And a constant distance maintaining mechanism for always maintaining a constant distance from the signature to the blocking action portion of the blocking member at the standby position, and the two series of blocking members are individually set to the standby position for each series. And stop The transport fold is provided so as to be movable between the storages, and the blocking position is set to a position slightly farther from the downstream end of the forced transport than the distance corresponding to the length in the transport direction of the first part of the signature. We propose a device for blocking and arranging books.

Further, in the blocking section device in which the blocking members have two series, the first blocking surface of the first blocking member and the second blocking surface of the second blocking member are substantially the same. There is proposed a blocking and sorting device for a transport signature row, which is provided so as to be a surface and is substantially parallel to the leading side of a signature to be transported.

Furthermore, in each of the above-mentioned blocking and sorting devices, a blocking and sorting device for a transport signature row is provided with an overstroke mechanism having a cushioning elastic member between the blocking member and the blocking moving means. To propose.

The first blocking member 21 descends between the first and second sheets, and the following signature B is blocked and divided by the first blocking action portion 211, the overlapping pitch P thereof is widened, and the interval P2 is opened. The state of the signature line A is shown.

In FIG. 7a, the signature line A, which is being counted by the counting device 7 with the signature B as the head, is conveyed.
For example, when the number of signatures reaches 25, which is the constant D, the control means 70 (see FIG. 4) calculates based on the counting completion signal, and the control signal output as a result operates the second pneumatic cylinder 20b. 2 The blocking member 22 descends, and as shown in FIG. 7b, the 26th copy, that is, the following signature B is blocked and the preceding signature row A is conveyed. Then, when the signature line A is expanded to the spread pitch P1 at which the accumulation processing device 6 located downstream can perform the accumulation process, the second blocking member 22 is returned to the standby position, and the succeeding signature line A is conveyed. To be done.

The counting device 7 sends the counting completion signal to the control means 7.
When it is output to 0, the number of copies of the following signatures B is continuously counted. For example, when the counting of three fractions is completed, at the position where the first blocking action portion 211 and the second blocking action portion 221 of the blocking device 2 are inserted into the upper surface of the signature array A, that is, at the blocking position Y. , The first blocking action portion 211 of the first blocking member 21 is lowered between the third and fourth sets of the conveyed signature line A, and the fourth copy is set as shown in FIG. 7c. That is, the leading leading signature B1 that follows is blocked, and the pitch can be widened so that the signature row A is similarly widened to the pitch P2.

When the rotary press is operating normally, as shown in FIG. 7b (see FIG. 5) to FIG. 7c (see FIG. 6), the fraction C is closed from the signature line A at the tail of the constant D. The closing and dividing step is repeated in a very small time margin of stopping and then closing the trailing signature B of the fraction C to obtain the constant C. For example, the number of double-sided copies of the signature B discharged from the folded portion of the newspaper press is currently 170,000 copies per hour or more (the number of single-sided copies discharged from a single folded portion is 85,000 copies per hour). It has become to. Assuming that the printing speed is 170,000 copies per hour, the transport speed of the signature B will be 24 copies per second, and the time for passing the blocking position Y will be 0 per copy of the signature. It is 0.042 seconds. For each passage time of this part, each pneumatic cylinder 20a, 20b
Since it takes a very long time to operate the first blocking member 21 and the second blocking member 22 that are operated by the above-mentioned method, the signatures are transported to the blocking position Y in advance in consideration of the time. When it is closed, the blocking action portion 21
1, 221 are inserted in the signature line A, and the first blocking member 21 and the second blocking member 22 are configured to block the signatures.
Each of the first blocking action portion 211 and the second blocking action portion 221 is lowered and returned to the standby position after a predetermined time has elapsed.

Further, the first conveyor 81, the second conveyor 82, the third conveyor 83 and the upper support conveyor 3
The transport speed of the same, the simple driving means,
At least the signature line A accurately sent out from the rollers R1 and R1 of the first conveyor 81, which is a sandwiching and conveying mechanism that allows the signature B at the counting position X by the counting device 7 to be forcibly conveyed by sandwiching it from the top and bottom, The second conveyor 8 having a step G lower than the conveyor 81 and having an open upper portion
It is transported to 2. The closing position Y is provided at a position slightly longer than the length corresponding to one copy of the signature, and the upper supporting conveyor 3 has the closing device 2 and the constant distance maintaining mechanism 4 on the upper part of the second conveyor 82. A blocking section device 1 is provided. Then, the signature B is accurately conveyed to the blocking position Y, and by the operation of the first blocking member 21 or the second blocking member 22 set at an appropriate timing,
Extremely accurate block segmentation is possible. The height dimension of the step G is set in the range of 0 to about 10 copies of the signature depending on the thickness of the signature B or the like.

Since the first blocking member 21 and the second blocking member 22 of the blocking device 2 are provided adjacent to each other at substantially the same location, the blocking is performed on the third conveyor 83 downstream of the blocking position Y. A device (sorting device) is not required, and the conveyance path is shortened by only conveying to the deposition processing device 6, and it is not necessary to provide an open portion in the middle thereof, and the signature line A is sandwiched from above and below securely. It can be transported.

By setting the speeds of the first conveyor 81, the second conveyor 82, and the third conveyor 83 to be the same speed, the signature line A sequentially passed to the downstream conveyors.
Since there is no speed difference between the transporting surface and each transport surface and no rubbing occurs, the surface of the signature B is not stained and the print quality is improved.

EFFECTS OF THE INVENTION At least a counting device is provided by a sandwiching and conveying mechanism.
You can forcibly transport the signature at the counting position from above and below,
Also, the blocking position is clamped from the downstream end of the transport mechanism to one copy of the signature.
Set at a position slightly farther than the equivalent length in the transport direction
By doing so, you can block the signatures immediately after the forced transportation is completed.
Since it is possible to perform the
You can eliminate the difference from the amount sent, and correctly classify the signatures.
It has become possible.

By installing a constant distance maintaining mechanism,
Regardless of the thickness, at the same timing for the movement amount of the signature
In the standby position, simply activate the blocking movement means.
The timing of the blocking action of the blocking member to the signature is always the same.
You can do the same.

The first blocking surface of the first blocking member and the second blocking surface of the second blocking member are provided so as to be substantially the same surface, and with respect to the leading side of the conveyed signature. Since the distances from the counting position to the blocking position can be set to the minimum required distance by providing them so as to be substantially parallel to each other, the path length of the conveyor can be minimized.

By providing the overstroke mechanism, even if the blocking member acts to press the upper surface of the preceding signature, which is not blocked, a large force acts to obstruct the conveyance of the signature. Because it does not stain the paper surface,
The signatures are transported smoothly and do not disturb the signature queue.

In other words, the conveyance state is stable, the blocking classification accuracy is improved, and it is possible to sort the signatures accurately and reliably even when the speed of the rotary press is increased. Since the signatures have been transported reliably, the same transport speed can be used, and the conveyor fast-forward drive is not required. Further, the friction of the paper surface due to the blocking action portion, the friction of the paper surface due to the difference in transport speed is reduced, and the rubbing stains on the paper surface are reduced, so that the print quality is improved and
It has become possible to reduce the size and manufacturing cost relatively.
