CONSTITUTION:When a friction is a kind in two, when, after division of substances to be conveyed into the set number of divisions, a boundary between substances to be conveyed equivalent to a quorum calculated from an amount of conveying and moving substances to be conveyed divided into the set number of divisions and substances to be conveyed equivalent to a first friction passes a third division device, a flow is switched from the one conveyance passage B on the downstream side to the other conveyance passage C on the downstream side by a third division device 24, and substances to be conveyed equivalent to the first friction conveyed through the conveyance passage C on the downstream side. When a boundary between substances to be conveyed equivalent to the first friction calculated from an amount of conveying and moving substances to be conveyed divided into the set number of divisions and substances to be conveyed equivalent to a second friction passes a second division device 20, the substances to be conveyed equivalent to the second friction are blocked for a given time, and after the third division device 24 is restored, the substances to be conveyed equivalent to the second friction are conveyed a given distance away from the substances to be conveyed equivalent to the preceding quorum through the same conveyance passage C on the downstream side.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is an object of the present invention to convey objects conveyed in continuous rows, for example, from the folding section of a rotary press under high-speed operation, in such a way that the rows are conveyed at a constant overlapping pitch. The present invention relates to an automatic counting and sorting device that counts printed matter being conveyed while maintaining the conveyance speed and separates it into a fixed standard number of copies (constant number) and a number of copies less than the standard number of copies (fractional number).

[Conventional technology]

Printed matter is printed in the printing section of a rotary press under high-speed operation, folded in the folding section, and conveyed in rows at a constant overlapping pitch, such as newspapers, by counting them while maintaining the conveying speed to obtain a fixed standard number of copies. Conventional automatic counting and sorting devices for printed matter that classify printed matter into (constant number) and copies (fraction) that are less than the standard number of copies are described, for example, in Japanese Patent Publication No. 56-38499 and Japanese Patent Publication No. 57-30724. There are two types: one type and the other type described in Japanese Patent Application Laid-Open No. 60-93059.

In the former type, the first sorting plate first sorts the total number of copies of the conveyed printed matter by the constant S and the fraction a, and then this total number is divided into the constant S by the second sorting plate.
A two-step classification is performed in which the printed matter is re-sorted into the printed matter of 1 and the printed matter of fraction a.

As a result, the row of printed matter being conveyed is alternately divided into printed matter of constant S and printed matter of fraction a. At this time, the operation of the second sorting plate is such that the printed matter of constant S is sent to the first conveying path downstream, and the printed matter of fraction a is sent to the second conveying path downstream, which is branched from the first conveying path. It also functions as an operation at the same time.

In the latter type, similarly to the former type, the line of printed matter being conveyed consists of a constant S of printed matter and a fraction a.
The printed matter of constant S by the second dividing plate is sent to the first conveyance path, and the printed matter of fraction a is sent to the second conveyance path branching from the first conveyance path. This sorting operation is not performed, and the printed matter of constant S and the printed matter of fraction a are alternately sent to the same downstream conveyance path. That is, in conjunction with the closing operation of the second dividing plate, the speed of the downstream conveying path is increased to a higher speed than that of the upstream conveying path, and as a result, the constant S leading to the printed matter of fraction a blocked by the second dividing plate is increased.
The printed matter is fast-forwarded and delivered to the stacker. Then, after a predetermined period of time has elapsed, the second dividing plate releases the fraction a of printed matter, and the printed matter is sent to the downstream conveyance path where the speed is reduced to the same speed as the upstream conveyance path.

[Problem to be solved by the invention]

A fixed standard number (constant) of printed matter that is conveyed in rows with a fixed overlapping pitch as described above in the conventional technology.
Regardless of the format of the automatic counting and sorting device for printed matter that separates printed matter into copies (fractional numbers) that are below the standard number of copies, in order to sort printed matter with a fractional number a, it is necessary to separate printed matter with a constant S before and after it. Therefore, it is impossible to continuously classify the printed matter of the fraction a, and it is impossible to obtain a group of printed matter of the fractional division that is larger than the group of printed matter of the constant division.

Therefore, for example, when shipping newspapers, if there is a large proportion of shipments using fractions a that are less than the constant S, such as local editions, if you try to obtain the required number of printed matter groups in the fractional category, you may end up with an extra group of printed matter in the constant category. occurs. In order to eliminate this waste, the total number of printed matter to be printed is taken as the required number of printed matter, and the constant and fractional divisions are performed alternately as described above. Disposal, that is, manual fractionalization must be performed, which requires a great deal of effort.

In order to eliminate the above-mentioned manual work, the printed matter that is conveyed in rows at a constant overlapping pitch at high speed is counted while maintaining the conveying speed, and when obtaining the fraction a of printed matter, the constant S is It is desired to continue sorting small number of copies (for example, 10 copies or less) without sorting the printed matter.

[Means to solve the problem]

The automatic counting and sorting device for printed matter according to the present invention is installed in a conveyance path for conveying objects in a continuous row, which is composed of an upstream conveyance path and a downstream conveyance path branched into a plurality of downstream sides of the upstream conveyance path.

[For production]

The objects to be conveyed are conveyed in a continuous line on the upstream conveyance path, divided into a desired set number, and sequentially conveyed through one downstream conveyance path to the downstream processing section for processing. The number of conveyance passages is constantly counted by a counter, and each time it reaches a set number, the conveyed objects being conveyed on the upstream conveyance path are intermittently blocked by the first sorting device and sorted into the set number. and transported downstream. ! If the constant is set as a constant, the objects to be transported that have been subjected to constant classification are transported sequentially on the downstream transport path at required intervals.

For fractional divisions, use 1, for example, set the number as a constant, or 2.
First, as in the constant division above, the first
Sort the set number using the sorting device.

If there is only one type of fraction, the second half of the fraction is further blocked for the required time when passing through the second sorting device at the boundary between the constant number and the fraction calculated from the amount of transport movement of the objects to be conveyed in the set number classification,
The objects are divided into a constant number in the first half and a fraction in the latter half, and the constant number of objects and the fraction of objects are sequentially transported on the downstream conveyance path with a required interval.

If there are two types of fractions, after the set number classification, when the boundary between the constant amount calculated from the conveyance movement amount of the conveyed objects in the set number classification and the first fraction amount passes through the third sorting device. , 3rd
The distribution is switched from one downstream conveyance path to the other downstream conveyance path by the sorting device, and in addition to a constant number of objects being conveyed in one downstream conveyance path, a first fraction of the objects are conveyed in one downstream conveyance path. The conveyed object is conveyed on the other downstream conveyance path. Along with that,
When the boundary between the first fraction and the second fraction calculated from the conveyance movement amount of the objects in the set number division passes through the second sorting device, the second fraction is blocked for the required time, and the third fraction is stopped. After the sorting device is returned to its position, it is transported along the same downstream transport path with a required interval for the preceding constant.

The timing and sequence of operation of each of the above-mentioned sorting devices can be set and combined as appropriate.

It consists of a belt conveyor 12.13.

The conveyance speed of all conveyance paths other than the first downstream conveyance path B is synchronized with the printing (discharge) speed of the rotary press, and one roller shaft in the belt conveyor in that conveyance path is equipped with a pulse generator ( A rotary encoder 14 is provided, connected to the control device, and configured to transmit a pulse signal corresponding to the number of rotations of the roller shaft, that is, the conveyance distance of the belt conveyor, and input it to the control device.

On the belt conveyor 2 of the upstream conveyance path A, there is a count start sensor 15 that detects the presence of each printed matter P in the row of printed matter conveyed and passed by the upstream conveyance path A, and a sensor 15 that constantly keeps track of the number of copies of printed matter P that also passes. A counting counter 16 is provided, both connected to the control device as well as the pulse generator 14.

The count start sensor 15 inputs a detection signal of the presence of each printed matter P in the row of printed matter to the control device, and the control device counts the count signal from the counter 16 only while receiving this signal. .

The auxiliary belt conveyor 5 provided opposite to the belt conveyor 2 is provided to improve the counting accuracy of the counter 16.

Between the downstream end of the belt conveyor 3 and the upstream end of the belt conveyor 4, a first dividing plate 17 is provided above so as not to close or open the upstream conveyance path A. That is,
The first partition plate 17 is fixed to the end of the piston rod of the pneumatic cylinder 18, and can be moved up and down between a closed position and an open position by the operation of the pneumatic cylinder 18. Additionally, a first guide plate 19 for subsequent printed matter is provided above the downstream end of the belt conveyor 3.

Similarly, the downstream end of the upstream conveyance path A and the first downstream conveyance path B
- A second dividing plate 20 is also provided between the upstream end of the second downstream conveyance path C so as not to close or open the upstream conveyance path A. That is, the second partition plate 20 is connected to the pneumatic cylinder 2
1, and can be moved up and down between a closed position and an open position by the operation of a pneumatic cylinder 21. Additionally, a second guide plate 22 for subsequent printed matter is provided above the downstream end of the belt conveyor 4.

1st. The second guide plate 19.22 is connected to the first guide plate 19.22. Second division plate 1
This is to prevent the subsequent printed matter from being disturbed when 7.20 is activated.

The auxiliary belt conveyor 8 of the first downstream conveyance path B and the belt conveyor 10 of the second downstream conveyance path C share the shaft 23 of the upstream roller, but the rollers of the two conveyors 8 and 10 are , and are individually rotatable about the shaft 23.

The third partition plate 24 is integrally connected to the swinging arm 25 in a bell crank shape, and the connection point is pivotally connected to the shaft 23 of the upstream roller so that it can swing freely around the coaxial line, and the swinging end of the swinging arm 25 is is pivotally connected to the piston rod end of the pneumatic cylinder 26. Then, the third dividing plate 24 is moved to the first downstream conveyance path open position, the second downstream conveyance path closed position, the first downstream conveyance path closed position, and the second downstream conveyance path by the operation of the pneumatic cylinder 21. It can be swung between the open position and the open position.

Each pneumatic cylinder 18.21.26 has a counter 1
It is operated under the control of a control device connected to 2.

The control device is equipped with an operation panel for inputting segmental operation data, and is also equipped with a control status indicator if necessary.

The driving device 27 of the belt conveyor 6.7 of the first downstream conveyance path B and the auxiliary belt conveyors 8, 9 is connected to the upstream conveyance path A.
There are two types: one that is connected to the drive device of the belt conveyor via a transmission, and the other that uses a separate electric motor.In the latter type, there is one that controls the rotation speed of the electric motor itself, and one that controls the rotation speed of the electric motor itself.
In some cases, a transmission is interposed in 7. The speed change of the drive device 27 is performed based on a command from a control device connected to the counter 16.

Then, in conjunction with the switching operation of the second dividing plate 20, the first downstream conveyance path B has a conveyance speed that is equal to the conveyance speed of the upstream conveyance path A, and a conveyance speed that is faster than the conveyance speed of the upstream conveyance path A. It is designed to be driven by switching to a high conveyance speed. That is, the conveyance speed of the first downstream conveyance B is switched to a higher speed than that of the upstream conveyance path A when the second dividing plate 20 is closed, and is switched to a higher speed than that of the upstream conveyance path A when the second dividing plate 20 is opened. It can be switched quickly.

A stacker 28, which is a downstream processing section, is installed downstream of the first downstream conveyance path B.

The operation and function of the above automatic counting and sorting device for conveyed items will be explained.

As mentioned above, the pulse generator (rotary encoder) 14 emits a pulse signal corresponding to the number of rotations of the roller shaft, that is, the conveyance distance of the belt conveyor, and inputs it to the control device. The distance from the counting position to each sorting position, which is the tip position of each sorting plate during sorting operation, can be replaced by the number of pulses of the pulse signal, and the moving distance and position of each printed matter P on the upstream conveyance path A can be calculated. obtain.

Therefore, the number of pulses corresponding to the distance between each of the first, second and third division positions and the counting position is Nl.
, N2. Let's call it N3.

First, the printed matter P is divided into constant numbers S, and the stacker 28
We will discuss the case where the material is transported to and processed.

In this case, the sorting operation is performed only by the first sorting plate 17, and the second sorting plate 20 and the third sorting plate 24 are maintained at positions that open the first downstream conveyance path B. Then, the first downstream conveyance path B is normally in a constant velocity state with the upstream conveyance path A.

Printed materials P, such as newspapers, printed in the printing section of a rotary press and folded in the folding section form continuous rows with a constant overlapping pitch and are transferred to the upstream conveyance path A (belt conveyors 1, 2, 3).
．． 4) The first dividing plate 1 is conveyed on the
7 to the constant S, and the first downstream conveyance path B
After that, it is transported to the stacker 28.

First, the printing operation is started, and when the leading printed matter of the row of printed matter conveyed on the upstream conveyance path A passes the count start sensor 15, it is counted by the count start sensor 15.
is detected, the detection signal is input to the control device, and in response to this, the control device starts counting the count signal from the counter 16. When the count reaches a constant S preset by operating the operation panel, the control device counts up and starts counting from 1 again, and also counts the pulse signal from the pulse generator 14. Therefore, it is Nl (if there is a time lag in the dividing operation of the first dividing plate 17, it is also taken into account)
The same applies to the division operation of the division plate 20 and the third division plate 24. When -) is reached, an operation command is issued to the pneumatic cylinder 18.

In response, the pneumatic cylinder 18 is activated, and the first dividing plate 17 is inserted between the trailing printed matter and the following printed matter of the preceding printed matter group Ps of constant S, and is conveyed on the upstream conveyance path A. The subsequent row of printed matter is blocked at the first sectioning position at the downstream end of the belt conveyor 3 by the first sectioning plate 17 in the closed position, and a constant S is placed on the conveyor belt 4.
A group of printed matter Ps is divided. The preceding print group Ps of constant S reaches the first downstream conveyance path B, is conveyed and discharged to the stacker 28 by the belt conveyors 6.7, 8.9, and is processed by the stacker 28. When the control device counts the number of pulses of the pulse signal corresponding to the processing time of the printed matter group Ps, the pneumatic cylinder 18 moves back in response to a command from the control device, and the first dividing plate 17 returns to the open position. . In this way, the necessary interval for stacking the preceding printed matter group Ps is secured, and the succeeding printed matter row is conveyed on the conveyor belt 4 in the same manner as the preceding printed matter group Ps.

On the other hand, the counter 16 after counting up the constant S
When the count number of the counting signal from reaches the constant S again,
The control device counts up again and further counts the pulse signal from the pulse generator 14 until it reaches N.
When it becomes 1, an operation command is issued to the pneumatic cylinder 18. Then, the constant division by the first division plate 17 described above is repeated.

In this way, the printed matter row is sequentially divided into printed matter groups Ps of constant S, and transported and discharged to the stacker 28.

Next, a case will be described in which a group of printed matter having fractions different from the constant S is classified.

Fractional setting input to the control device for fractional division is performed using the operation panel for inputting division operation data before or during the sorting operation, and fractional division is performed by interruption as appropriate during the constant division operation. .

Then, for example, Xi, N2. N3. N4. In the setting input of five types of fractions of N5, xl and N2. N3 and N
4. Divided into 3 groups with N5, Xi, N2. N3
In the three cases of xl and N2. N3 is divided into two groups, each fraction group is inserted between the constant S divisions for each group, and one constant and one fraction group are combined.

First, to describe the case where the fraction group is one type of fraction, the constant S
A group of printed matter Ps+xl having a child fraction x1 is divided by the first dividing board 17. That is, when re-counting after counting up the count signal of the preceding printed matter group Ps of constant S, the count number is the constant S terminal fraction x that was set and input by operating the operation panel.
Once it reaches 1, the control device counts up and counts up to 1 again.
At the same time, the pulse signal is further counted, and when the pulse signal reaches N1, an operation command is issued to the pneumatic cylinder 18.

In response to this, the pneumatic cylinder 18 is actuated, and the first dividing plate 17 is divided into a group of printed matter Ps+ of the preceding constant S terminal number xl.
The subsequent row of printed matter inserted between the tail end of xl and the following printed matter and conveyed on the upstream conveyance path A is moved to the downstream end of the belt conveyor 3 by the first dividing plate 17 in the closed position. It is stopped at one sorting position, and a group of printed matter Ps+xl having a constant number of S fractions x1 is conveyed on the conveyor belt 4 in a sorted manner.

Among the printed matter group Ps+xl, the printed matter group Ps with constant S in the first half
At the point in time when the end of the signal passes through the second division position (the point in time when the constant S count signal is counted and the N2 pulse signal is counted), the control device issues an operation command for the pneumatic cylinder 21 and the first downstream side A command to increase the speed of the belt conveyor speed increasing means of the conveyance path B is issued, and in response to this, the pneumatic cylinder 21 is operated, and the second dividing plate 20 is moved to the printed matter group P s+xl.
The belt conveyors 6.7 and 8.9 of the first downstream conveyance path B are inserted between the first half of the group of printed matter Ps of constant S and the second half of the group of printed matter Pxl of fraction x1, and the speed of the belt conveyors 6.7 and 8.9 of the first downstream conveyance path B is increased. the result.

The second half of the printed matter group Pxl, which is the fraction
It is stopped at the sorting position, the printed matter group Ps+xli±, the constant S
and the fraction Xi, and the printed matter group Ps of the constant S in the first half
is the belt conveyor 6 of the first downstream conveyance path B whose speed has been increased.
．． 7.8.9, it is transported and discharged to the stacker 28,
It is processed in a stacker 28.

After the first dividing plate 17 is closed and the number of pulses of the pulse signal corresponding to the time during which the first half of the printed matter group Ps of constant S is stacked is counted, the control device issues an operation command to the pneumatic cylinder 21 and 1 Issue a deceleration command to the belt conveyor speed increasing means on the downstream conveyance path B, and upon receiving it,
As the pneumatic cylinder 21 moves back, the belt conveyors 6.7 and 8.9 of the first downstream conveyance path B decelerate.
It will return to normal speed. As a result, the second dividing plate 20, which has reached the open position, opens the second half of the printed matter group Pxl of the fraction x1.

The printed matter group Pxl is conveyed and discharged to the stacker 28 by the belt conveyors 6.7, 8.9 of the first downstream conveyance path B at normal speed, and is processed by the stacker 28.

Since the first half of the printed matter group Ps with a constant S is transported and discharged by the accelerated first downstream conveyance path B, the transportation time is shortened, and due to this shortening, the second half of the printed matter group Pxl with a fractional number XI is processed by the stacker 28. Time will be secured.

After the first dividing plate 17 is closed, when the number of pulses of the pulse signal corresponding to the time during which the first half of the printed matter group Ps of constant S of the printed matter group Ps+xl is stacked is counted.
The pneumatic cylinder 18 moves back in response to a command from the control device.
The first partition plate 17 returns to the open position. In this way, the subsequent printed matter series is conveyed on the conveyor belt 4 at the required intervals in the same manner as the preceding printed matter group Ps+xl.

On the other hand, the count signal from the counter 16 after the previous count-up of the constant S terminal number X1 is counted again by the control device, and the subsequent division cycle of the predetermined number of divisions begins.

Regarding the case where the fraction group consists of two types of fractions,
In the same way as for the constant division above.

Printed matter group P s+x2+ of constant S fraction x2+fraction x3
x3 is divided by the first dividing plate 17. That is, in re-counting after counting up the count signal of the preceding group of printed matter, when the count reaches the constant S terminal number x 2 + fraction x 3 set and inputted by operating the operation panel, the control device starts the count up. Then, it starts counting again from 1, and also counts the pulse signal, and when it reaches N1, it issues an operation command to the pneumatic cylinder 18.

In response to this, the pneumatic cylinder 18 is activated, and the first dividing plate 17 is inserted between the end of the printed matter group Ps+x2+x3 of the preceding constant S fraction x2+fraction x3 and the following printed matter, and is transported to the upstream side. The subsequent row of printed matter conveyed on the path A is blocked at the first dividing position at the downstream end of the belt conveyor 3 by the first dividing plate 17 which is in the closed position.
On the conveyor belt 4, a group of printed matter Ps+x2+x3 of a constant S fraction x2+fraction x3 is conveyed in sections.

The time point when the end of the printed matter group P's of the first constant S in the printed matter group P s+x2+x3 passes the third division position (
After the count signal of constant S has been counted and the pulse signal of N3 has been counted), the control device issues an operation command to the pneumatic cylinder 26, and the air cylinder 26 operates accordingly, and the swinging arm 25 , the third dividing plate 24 closes the first downstream conveyance path B and also closes the second downstream conveyance path B.
Open the downstream conveyance path C.

As a result, the first group of printed matter Ps with constant S is guided toward the first downstream conveyance path B, and the group of printed matter Px2 at the middle end a×2
is guided toward the second downstream conveyance path C, and is conveyed along the same conveyance path C to a downstream processing section (not shown).

The point in time when the end of the printed matter group Px2 of the intermediate fraction x 2 passes the second division position (the point in time when the pulse signal of N2 is counted after the count signal of the constant S fraction x 2 is counted)
Then, the control device issues an operation command for the pneumatic cylinder 21 and a speed increase command for the speed increase means of the belt conveyor drive unit W27 of the first downstream conveyance path B, and in response to this, the pneumatic cylinder 21 operates and the first The two-section board 20 has an intermediate fraction x2
is inserted between the group of printed matter Px2 and the trailing group of printed matter Px3 of fraction x3, and the belt conveyor 6°7.8.9 of the first downstream conveyance path B is accelerated. As a result, the trailing printed matter group Px3 with the fraction x3 is the second
The belt conveyor 4 is blocked at a second dividing position at the downstream end by the dividing plate 20 . The first group of printed matter Ps of constant S that has already been guided to the first downstream conveyance path B is conveyed and discharged to the stacker 28 by the belt conveyor 6.7° 8.9 of the first downstream conveyance path B whose speed has been increased. and processed in the stacker 28.

On the other hand, at the time when the end of the group of printed matter Px2 with the intermediate fraction X2 passes through the third division position (after the count signal of the constant S fraction x2 is counted and the pulse signal of N3 is counted), the control device issues a return command for the pneumatic cylinder 26, and in response, the air cylinder 26 moves back and swings the swing arm 25, so the third partition plate 24 opens the first downstream conveyance path B and , the second downstream conveyance path C is closed.

After the second partition plate 20 is closed, when the number of pulses of the pulse signal corresponding to the time during which the first group of printed matter Ps of constant S is stacked is counted, the control device issues a backward movement command of the pneumatic cylinder 21 and Issue a deceleration command to the speed increasing means of the belt conveyor drive device 27 of the first downstream conveyance path B,
In response, the pneumatic cylinder 21 moves back and the belt conveyors 6.7, 8.9 of the first downstream conveyance path B
slow down.

It will return to normal speed. As a result, the second dividing plate 2° releases the trailing fraction x2 of the printed matter group Px2, and the printed matter group P
x2 is conveyed and discharged to the stacker 28 by the belt conveyors 6.7, 8.9 of the first downstream conveyance path B at normal speed, and is processed.

Since the first group of printed matter Ps with a constant S is transported and discharged by the first downstream conveyance path whose speed is increased, the conveyance time is shortened, thereby securing the processing time in the stacker 28 for the group of printed matter Px2 of fraction x2. will be done.

After the first partition plate 17 is closed, the printed matter group PS+12+x
When the number of pulses of the pulse signal corresponding to the time during which the printed matter group Ps of constant S at the beginning of 3 is stacked is counted, the pneumatic cylinder 18 moves back in response to a command from the control device, and the first dividing plate 17 , return to the open position. In this way, the subsequent print series is conveyed on the conveyor belt 4 at the required intervals in the same way as the preceding print series Ps+x2+x3.

In either case, the initial state is returned, but it is easy to understand that the usual division of the constant S may be carried out again, and that the division of various fractions may be repeated in the above manner. It will be.

〔Effect of the invention〕

According to the automatic counting and sorting device for conveyed objects according to the present invention,
When dividing conveyed objects such as printed matter that are conveyed in rows at a constant overlapping pitch into a fixed standard number (constant) and a number of copies less than the standard number (fraction), a constant number is used as in conventional technology. Since there is no need to alternately classify the transported objects and fractional transported objects, even if there is a large proportion of fractional classifications that are less than a constant, there is no need to manually make surpluses for the shortfall in the group of printed matter classified into fractional numbers. There is no need to reclassify fractions of a group of printed materials in constant classification, saving a great deal of labor and improving work efficiency.
