BACKGROUND OF THE INVENTION
The present invention relates to an underlay supply device that is provided in an integrated bundling process line and supplies an underlay material to a lower side of an accumulation body in which flat objects are stacked in the vertical direction. The present invention relates to an underlay supply device that selectively supplies either a highly flexible underlay material or a low flexibility underlay material.
For example, it is used in an integrated bundling process line for bundling newspapers, which are flat objects, in a newspaper production dispatch department.
[0002]
[Prior art]
Conventionally, in the newspaper production shipping department, when stacking newspapers printed and folded on a rotary press and transporting them as a newspaper aggregate, the bottom newspaper of the newspaper aggregate is prevented from being soiled or damaged, In order to facilitate post-processing operations (for example, bundling and packaging operations), underlay materials are laid on the underside of newspaper aggregates (for example, “Latest Newspaper Production Major Equipment” Japan Co., Ltd.) Newspaper Association, May 17, 1986, see page 420).
[0003]
As an apparatus for supplying and laying underlay material on the lower side of a newspaper aggregate in the prior art, for example, there is one disclosed in Japanese Patent Publication No. 48-43221.
The apparatus disclosed in Japanese Patent Publication No. 48-43221 is provided on the lower side of the moving surface of the newspaper stack, and is provided above the cradle for storing the laying paper (laying material) in a stacked state. A paper feed roller that is driven and rotated by a predetermined angle, is provided above the paper feed roller and slightly shifted in a direction away from the cradle, and is driven and rotated separately from the paper feed roller. And a drawing roller whose top is slightly higher than the moving surface of the newspaper stack, and a guide plate provided to face the outer surface of the drawing roller on the side farther from the cradle with a small gap, and The uppermost surface of the base sheet of the cradle is configured so that it can always contact the outer peripheral surface of the drawing roller.
[0004]
According to this configuration, first, the paper feed roller is driven and rotated to feed the top sheet of the laying paper of the receiving table along the guide plate, and the tip slightly protrudes from the moving surface of the newspaper stack. Stop at the specified position and wait. Next, when the newspaper aggregate is transported and moved, the leading end of the waiting sheet is sandwiched between the lower end leading edge of the newspaper aggregate and the drawer roller slightly higher than the moving surface, and the drawer roller is driven and rotated. Is pulled out on the moving surface and sent in the transport direction together with the newspaper aggregate while being laid between the newspaper aggregate and the moving surface.
[0005]
The device disclosed in Japanese Patent Publication No. 48-43221 is an underlay material supply device that supplies a highly flexible underlay material. However, in the case of a newspaper aggregate with a small amount of stacked newspapers, the device is highly flexible. When the underlay material is bound, it loses the binding force of the binding material, and the newspaper aggregate is crushed.
[0006]
Therefore, an underlay material supply device for supplying underlay material with low flexibility as disclosed in Japanese Patent Publication No. 6-59966 and Japanese Utility Model Publication No. 6-40200 has also been proposed.
The apparatus disclosed in Japanese Examined Patent Publication No. 6-59966 uses corrugated paper as a low-flexibility underlaying material, and an upstream conveyor and a downstream conveyor that form a transport surface for transporting a newspaper stack are used as newspapers. Conveying means for transporting the stack, can be stored in a state where the corrugated paper of the underlaying material provided in the side portion of the transporting device is stacked, and the stacked corrugated paper is taken out to the side in order from the lowest one Corrugated paper storage means, corrugated paper take-out means for taking out the lowermost corrugated paper from the corrugated paper storage means and moving it below the upstream conveyor; Corrugated cardboard paper moved by the corrugated paper take-out means below the upstream conveyor is downstream from between the upstream conveyor and the downstream conveyor. It is configured to include a corrugated paper feeding means for feeding the conveying surface of the Nbeya.
[0007]
According to this configuration, the corrugated paper take-out means operates to take out the lowermost corrugated paper from the corrugated paper storage means, move it below the upstream conveyor of the conveying means, and wait. Next, when the newspaper aggregate is transported and moved, the corrugated paper feeding means is operated, and the corrugated paper waiting means is moved from between the upstream conveyor and the downstream conveyor to the transport surface of the downstream conveyor at the same speed as the transport speed of the transport means. Send out.
[0008]
The fed corrugated paper is conveyed with the newspaper aggregate while being laid between the newspaper aggregate and the moving surface. When the corrugated paper feeding means operates, the downstream side of the corrugated paper feeding means and the downstream side of the upstream conveyor are displaced upward, and the upstream side of the downstream conveyor is displaced downward, so that the conveyance surface of the downstream conveyor is waiting. A supply port for supplying the corrugated paper to the lower side of the newspaper stack is formed.
[0009]
The apparatus disclosed in Japanese Utility Model Publication No. 6-40200 is similar to the apparatus disclosed in Japanese Patent Publication No. 6-59966, and corrugated paper is used as a low-flexibility underlay material. A transport means for transporting newspaper aggregates is formed with the downstream conveyor, and transport means for transporting the newspaper aggregates between the upstream conveyor and the downstream conveyor is provided under the downstream conveyor, and the corrugated paper sheets of the underlay are stacked and stored. Corrugated paper storage means capable of taking out the stacked corrugated paper from the uppermost one in order from the uppermost conveyor, and the uppermost one of the corrugated paper provided above the corrugated paper storage means. Cardboard paper take-out means to be taken out from the cardboard paper storage means and moved below the upstream conveyor and cardboard paper take-out Stage is configured with a corrugated paper feeding means for feeding the conveying surface of the downstream conveyor from between the corrugated cardboard is moved below the upstream conveyor and the upstream conveyor and the downstream conveyor.
[0010]
According to this configuration, first, the corrugated paper take-out means operates to take out the stacked corrugated paper from the corrugated paper storage means in order from the uppermost one, move it below the upstream conveyor, and wait. Next, when the newspaper aggregate is transported and moved, the corrugated paper feeding means is operated, and the corrugated paper waiting means is moved from between the upstream conveyor and the downstream conveyor to the transport surface of the downstream conveyor at the same speed as the transport speed of the transport means. Send out.
[0011]
The fed corrugated paper is conveyed with the newspaper aggregate while being laid between the newspaper aggregate and the moving surface. When the corrugated paper feeding means operates, the downstream side of the corrugated paper feeding means is displaced upward and the upstream side of the downstream conveyor is displaced downward, so that the transport surface of the downstream conveyor is relatively relative to the waiting corrugated paper. The supply port for supplying the corrugated paper to the lower side of the newspaper stack is formed.
[0012]
[Problems to be solved by the invention]
Any of the above-mentioned conventional underlay material supply devices provided in the integrated bundling process line is one type of underlay material in terms of flexibility, that is, either a highly flexible underlay material or a less flexible underlay material. Only one of them can be supplied. On the other hand, a stacking device that stacks and stacks flat objects, such as newspapers, upstream of the underlay material supply device stacks the flat objects in an appropriate number as long as it does not exceed the stacking capacity of the device. Because it has the ability to obtain, a stack, such as a newspaper stack, sent downstream from the stacking device is a comparatively large stack of many flat objects and a small stack of flat objects. Some of them have a small stacking height.
Here, a relatively large stacking height does not cause any problem deformation due to the subsequent tightening force of the binding, but a relatively small stacking height is caused by the subsequent tightening force of the binding. It will be crushed and the problem that the quality of a flat thing will be impaired remarkably arises.
[0013]
Therefore, the integrated bundling process line is
(1) Provide an underlay material supply device for supplying an underlay material with low flexibility, and supply an underlay material with low flexibility to all the aggregates regardless of the stacking height,
(2) Accumulation sent out downstream from the accumulator by arranging an underlay material supply device for supplying a highly flexible underlay material and an underlay material supply device for supplying a low-flexibility underlay material in series or in parallel. An underlay material supply device that supplies a highly flexible underlay material and an underlay material supply device that supplies a low flexibility underlay material according to the stacking height of the body, that is, according to the strength against the binding fastening force Can be installed to supply the underlay material according to the strength against the binding tightening force of the aggregate
Will do.
[0014]
  But,1 of said (0013)In this case, since the underlaying material having low flexibility is expensive, there remains a problem that the running cost is extremely high.
  or,2 of said (0013)In this case, when two types of underlay material supply devices are arranged in parallel, a transport line for distributing the two types of underlay material supply devices is required.seriesWhen a distribution line is placed, the transport line from the underlay material supply device located far from the accumulation device to the underlay material supply device far from the accumulation device is required. May cause a case where it is impossible to prevent the bottom flat object of the aggregate, which is the purpose of supplying the underlaying material, from being damaged, and the accumulation and binding process line becomes long and complicated. Therefore, the installation area of the stacking and binding process line becomes large, and each stack is made up of two underlay material supply devices according to the stacking height of the stack, that is, according to the strength against the binding tightening force.EitherConveying means and a control device for selectively feeding the crab are required, and the cost for the installation increases, and labor and materials necessary for maintenance and inspection also increase.
[0015]
The present invention combines a mechanism for supplying a low-flexibility underlay material and a mechanism for supplying a low-flexibility underlay material, and selectively operates the two mechanisms based on a signal from the stacking device. The above-mentioned problem is solved by providing an underlay material according to the size of the aggregate by providing the operation control means.
[0016]

Accordingly, either one of the first underlaying material and the second underlaying material can be selectively supplied to the lower surface of each of the stacks delivered by the stacking device.
[0018]
  The above-mentioned underlay material supply device stacks and accumulates flat products that are continuously produced by an accumulation device, and whenever a preset number of accumulations are completed,This is a pulse signal having a different phase based on the thickness of the integrated body sent out by the integrated device or a signal output as a “1” or “0” signal.The integrated body sending signal is output and the integrated body is sent out.
[0019]
In the underlay material supply device provided downstream of the stacking device, the operation control means can selectively operate one of the first underlay material supply means and the second underlay material supply means based on the integrated body sending signal. In addition, when it is sensed that the aggregate corresponding to the aggregate delivery signal has arrived at a predetermined position, the operation control of the underlay material supply means which has been enabled is started. In other words, while the transporting means sends out the flat object accumulation downstream, the supply mechanism of the underlay material supplying means to be controlled is operated, and the flat object is supplied from the underlaying material supply port provided downstream of the conveying means. The underlay material corresponding to the aggregate is supplied to the lower surface of each aggregate.

Further, when the craft paper 92 is not waiting at a predetermined position of the craft paper guide standby unit 42b of the second underlay material supply means 40, the craft paper take-out unit 42a is operated and a predetermined position of the craft paper guide standby unit 42b is operated. Makes the kraft paper 92 stand by.
(Refer to the state where one cycle of the underlay material supply operation is completed later.)
[0049]
Then, in the stacking apparatus B of the stacking and binding process line H, a newspaper which is a flat object of a predetermined building page (a building page input by the input means K) from the newspaper rotary press is loaded by the transport apparatus G1 on the stacking apparatus B. Are stacked in the stacking apparatus B and sequentially stacked to form a stack J.
[0050]
At that time, the accumulation device creation control unit BC5 causes the accumulation device B1 to count the number of newspapers M of the accumulation material creation data KS input from the first storage unit BC1 from the newspapers conveyed by the conveyance device G1, The counted newspapers are accumulated.
That is, the counted newspapers are stacked on the delivery conveyor section B2, and waiting for the stacking of the number M of copies to be completed, that is, with a time delay from when the Mth newspaper is counted until the stacking apparatus B is stacked. The feed operation signal is output to the delivery conveyor unit B2 and the pusher unit B3, and the delivery operation signal is output as an output timing signal to the signal output unit BC4 of the integrated device control means BC.
[0051]
Then, the conveyor part B2 and the pusher part B3 to which the delivery operation signal is inputted operate, that is, in FIG. 1, the conveyor of the delivery conveyor part B2 rotates counterclockwise, and the pusher part B3 moves to the left. Then, the aggregate J corresponding to the aggregate creation data KS is sent out from the delivery port B1 of the accumulation apparatus B toward the underlay material supply apparatus A.
[0052]
On the other hand, in the stacking device control means BC, the creation data KS of the created aggregate J input from the input means K and stored in the first storage unit BC1 is input to the comparison unit BC3, and the comparison unit The base material supplied to the integrated body J stored in the second storage unit BC2 by BC3 is the first base material (corrugated cardboard) having low flexibility, or the second base material having high flexibility (craft paper) ), The data regarding the thickness of the stack J, that is, the stack count boundary value M0 corresponding to the number of newspaper pages included in the creation data KS of the stack J is extracted.
[0053]
The comparison part BC3 compares the number M of the accumulated parts in the aggregate creation data KS input from the first storage part BC1 and the boundary value M0 of the number of accumulated parts taken out from the second storage part BC2, and the magnitude relationship between them is the result. That is, depending on whether M is equal to or greater than M0 or M is less than M0, it is specified whether the underlay material supplied to the aggregate J to be created is the first underlay material (corrugated cardboard) or the second underlay material (craft paper). The signal is output to the signal output unit BC4.
[0054]
Then, the signal output unit BC4 supplies an underlay material to be supplied to the produced and delivered assembly J with the timing when the assembly delivery operation signal from the assembly creation control unit BC5, that is, the output timing signal is input. An underlay material feed signal BS including the specified contents is output.
[0055]
In the illustrated embodiment, the underlay material feed signal BS is output as a rising pulse signal or a falling pulse signal, and the rising pulse signal specifies the supply of a second flexible underlay material (craft paper 92). The falling pulse signal designates the supply of the first underlay material (corrugated cardboard 91) having low flexibility.
[0056]
The underlay material feed signal BS output from the signal output unit BC4 of the stacking device control means BC is input to the operation control means 50 of the underlay material supply apparatus A. The underlay material feed signal BS input to the operation control means 50 is input to the flip-flop circuit 51b as it is, and is inverted by the NOT circuit 55 and input to the flip-flop circuit 51a.
[0057]
When the underlay material delivery signal BS is a falling pulse, the flip-flop circuit 51a immediately outputs a “Hi” signal at the rising edge of the rising pulse inverted by the NOT circuit 55, while the flip-flop circuit 51b Before the rising edge of the falling pulse returns, the “Hi” signal of the flip-flop circuit 51a is input and cleared. This prevents the rising edge of the falling signal from returning and prevents the “Hi” signal output. There is nothing to do.
[0058]
The “Hi” signal of the flip-flop circuit 51a is input to the AND circuit 52a. In the AND circuit 52a, as a timing signal for starting the underlay material supply operation, a timing signal for detecting that the integrated body J sent from the stacking apparatus B has been transported and transported to a predetermined position and outputs a detection signal. When the output signal of the output unit 53 is input and the AND condition of the “Hi” signal of the flip-flop circuit 51a and the timing signal of the timing signal output unit 53 is satisfied, the signal that activates the first underlay material supply control unit 54a Is output.
[0059]
Then, in the first underlay material supply control unit 54a, first, the first timer and the second timer start timing, one cycle for the first underlay material supply starts, and from the first underlay material supply control unit 54a A signal is output to the flip-flop circuit 51a, and the flip-flop circuit 51a goes down.
[0060]
The press roller 32d is raised by a signal output after the first timer has timed a predetermined time, and the feeding endless belt 32c and the conveying means 10 are placed on the cardboard standby position 32e via the cardboard 91 waiting. It is pushed up and becomes an inclined state with the underlaying material supply port 20 side up (see FIG. 4).
[0061]
Next, the sending endless belt 32c is activated by a signal output after the second timer finishes measuring a predetermined time, and the cardboard 91 waiting at the cardboard standby position 32e is transferred to the transport means 10 by the assembly J. The corrugated cardboard 91 is fed to the lower surface of the stacked body J passing through the underlaying material supply port 20 at the same speed as the continuous conveyance.
[0062]
In addition, the third timer and the fourth timer start timing by a signal output from the second timer. The sending endless belt 32c is stopped by the signal output after the third timer has timed a predetermined time, and the supply of the cardboard 91 to the stack J is ended.
Subsequently, the press roller 32d is lowered by a signal output after the fourth timer has timed a predetermined time, and the sending endless belt 32c and the conveying means 10 are returned to their normal positions.
[0063]
Then, the corrugated cardboard take-out section 32a operates according to a signal output by detecting that the sending endless belt 32c and the conveying means 10 have returned to the substantially horizontal normal position by the appropriately provided first detection switch 54a1. The lowermost cardboard 91 stacked in the first storage unit 31 is started and taken out to the cardboard standby position 32e to be put on standby, and one cycle of the supply operation of the cardboard 91 as the first underlay material is completed.
[0064]
When the underlay material sending signal BS is a rising pulse signal, the flip-flop circuit 51b immediately outputs a “Hi” signal at the rising edge of the rising pulse, while the flip-flop circuit 51a is inverted by the NOT circuit 55. The “Hi” signal of the flip-flop circuit 51b is input and cleared before the rising edge of the falling pulse signal returns, and the rising edge of the falling pulse signal is prevented from acting. There is no output.
[0065]
The “Hi” signal of the flip-flop circuit 51b is input to the AND circuit 52b.
In the AND circuit 52b, as a timing signal for starting the underlaying material supply operation, a timing signal for detecting that the integrated body J sent from the stacking apparatus B is transported and transported to a predetermined position and outputs a detection signal. When the output signal of the output unit 53 is input and the AND condition of the “Hi” signal of the flip-flop circuit 51b and the timing signal of the timing signal output unit 53 is satisfied, the signal that activates the second underlay material supply control unit 54b Is output.
[0066]
Then, in the second underlaying material supply control unit 54b, first, the fifth timer starts timing, one cycle for supplying the second underlaying material starts, and the second underlaying material supply control unit 54b starts the flip-flop circuit 51b. Signal is output to the flip-flop circuit 51b.
[0067]
The craft paper take-out section 42a and the craft paper delivery section 42c are driven and rotated by a signal output after the fifth timer has counted the predetermined time. That is, the take-out endless belt 42d, the first roller 42e, the second roller 42f, and the pair of delivery rollers 42g are driven and rotated.
[0068]
By the driving rotation of the pair of delivery rollers 42g, the craft paper 92 waiting in the craft paper guide standby section 42b is sent out from the underlaying material supply port 20 at the same speed as the transport means 10 transports the aggregate J, The kraft paper 92 is supplied to the lower surface of the aggregate J that passes through the underlay material supply port 20.
[0069]
The driving rotation of the pair of delivery rollers 42g is continued until stopped by a signal output from a third detection switch 54b3 described later. Further, when the craft paper 92 is moved by a predetermined distance from a predetermined standby position by the driving rotation of the pair of feeding rollers 42g, a signal output from the third detection switch 54b2 is detected and a signal during driving rotation is detected. The first roller 42e is lowered and brought into contact with the uppermost kraft paper 92a stacked on the second storage unit 41.
[0070]
The uppermost craft paper 92a is taken out by the rotating first roller 42e toward the craft paper guide standby unit 42, and is sandwiched between the take-out endless belt 42d and the second roller 42f, and further on the craft paper guide standby unit 42 side. Moved to.
[0071]
Next, the first roller 42e is raised by a signal output from the second detection switch 54b1 by detecting the leading end of the moved kraft paper 92, and the kraft paper 92a is brought into contact with the take-out endless belt 42d and the first belt 42d. The craft paper guide standby unit 42 is moved only by the two rollers 42f, and eventually reaches the position of the pair of delivery rollers 42g, and the craft paper guidance standby by the take-out endless belt 42d, the second roller 42f, and the pair of delivery rollers 42g. The unit 42 is taken out to a predetermined standby position, and the next supply of kraft paper to the lower surface of the stacked body J is prepared.
[0072]
Then, the take-out endless belt 42d, the second roller 42f, and the pair of delivery rollers 42g are all stopped by the signal output from the third detection switch 54b3 by detecting the leading end of the kraft paper 92a, and the second underlay. One cycle of the supply operation of the kraft paper 92 as the material is completed.
[0073]
Needless to say, the same operation control as described above may be performed by setting the underlay material sending signal BS to be “1” and “0” signals and the operation control means 50 as a CPU.

[0074]
【The invention's effect】
According to the present invention, in the downstream side of the stacking device having the capability of stacking a flat object in an appropriate desired number, when the stacks sent from the stacking device have various stacking heights In other words, there are cases where there is a mixture of a material that does not cause any deformation due to the binding tightening force and a product that is crushed by the binding tightening force and the quality of the flat object is significantly impaired. However, in accordance with a predetermined standard in accordance with the strength of the stack with respect to the binding tightening force, one underlay material supply device can be inexpensive for the stack that does not cause any deformation due to the binding tightening force. A relatively expensive low-flexibility underlayment is automatically applied to an assembly that supplies a high-flexibility underlayment, which may be crushed by the tightening force of the binding and may significantly impair the quality of flat objects. It is possible to selectively supply.
[0075]
Therefore, it is possible to eliminate waste in terms of running costs that existed when supplying a low-flexibility underlay material to all the stacked bodies regardless of the difference in strength of the stacked bodies with respect to the binding tightening force.
[0076]
Further, according to the present invention, a highly flexible underlay material is supplied so as to avoid supplying a low-flexibility underlay material to all the integrated bodies regardless of the strength of the above-described integrated bodies. An underlay material supply device and an underlay material supply device for supplying a low-flexibility underlay material are arranged in series or in parallel, depending on the stacking height of the aggregate fed from the accumulation device to the downstream side, that is, the binding tightening force Depending on the strength of the material, the material is fed into either an underlay material supply device that supplies a highly flexible underlay material or an underlay material supply device that supplies a low flexibility underlay material to The problem that occurs when the underlay material corresponding to the strength is supplied is also solved.
[0077]
In other words, there is a case where the moving distance of the stack from the stacking device to the underlay material supply device becomes long, and it is not possible to prevent the bottom flat object of the stack, which is the purpose of supplying the underlay material, from being damaged or damaged. There is no fear, and further, there is no need for a conveying means and control device for feeding each aggregate to an appropriate underlay material supply device according to the strength of the aggregate against the binding tightening force. Thus, the configuration is simplified, so that the installation area of the integrated bundling process line can be reduced, the cost for installing the integrated bundling process line can be reduced, and the labor and materials required for maintenance and inspection are also reduced.
