Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material feeding apparatus for feeding a sheet material from a roll, drawing out the fed sheet material at a high speed, and supplying the sheet material.

[0002]

2. Description of the Related Art In an automated or semi-automated production line, various processing devices are arranged in a product transport path, and various processes are performed at intervals depending on a product transport pitch, thereby increasing production efficiency. it can. At this time,
If a specific process takes a long time, as a result, the so-called Door T
o Door time becomes longer (throughput decreases),
Overall production efficiency is reduced.

[0003] The inventor paid attention to a process of protecting a surface of a product by covering a product conveyed one after another with a sheet material such as paper. For example, the present inventor has focused on a siding material production line that is widely used instead of wood and plastic as a building outer wall material. This siding material constitutes a decorative surface (surface used for the outer wall surface) by, for example, an iron-coated steel plate, an aluminum-coated steel plate, a film-laminated steel plate, a film-laminated aluminum steel plate, a stainless-coated steel plate, an embossed steel plate, and the like. In addition, a rigid foam having high heat insulation properties and a gypsum board having high sound insulation properties are employed. The siding material can be produced, for example, by rolling or rolling a rolled steel plate of aluminum or iron and filling or bonding the core material while cold-forming the rolled steel plate, and finally cutting it to a fixed size. The siding material cut to a fixed size is stacked and packed.At this time, a sheet material such as paper is interposed between the facing surfaces of the decorative surfaces in the stacking process so that the decorative surface of the siding material is not damaged. Is required.

[0004]

However, in the case where the paper is unwound from a roll and put on a long material such as a siding material in a short time, the speed of paper drawing must be increased. It was clarified that rotating a roll having a large mass at a speed equal to the pulling speed was not advisable because the power of the roll drive system became excessive. Thus, when the roll is rotated at a relatively low speed and the paper is unwound from the roll, and when the unwound paper is to be pulled out at a high speed, it is necessary to reliably absorb the speed difference and to supply the paper smoothly. Found by the inventor.

An object of the present invention has been made in view of the above circumstances, and a sheet material that can be drawn out from a roll by rotating the roll at a relatively low speed, and that the fed sheet material can be drawn out quickly and smoothly. An object of the present invention is to provide a material supply device.

[0006]

According to the present invention, there is provided a sheet supply apparatus comprising: a supply section (70) for supplying a sheet material (IP) from a roll (701); and a supply section for supplying the sheet material (IP) from the supply section. A drawer (75) for pulling out the sheet material from the supply unit while running with the front end held so as to be detachable by the chuck (756) is provided. The supply unit includes:
A plurality of tension rollers (703 to 70)
5) and a feeding mechanism for feeding the sheet material from the roll through the feeding rollers (706, 707), a cutter (720) for cutting the sheet material being drawn by the drawing means at a predetermined position, and a cutter from the feeding mechanism after cutting. And a brake means (710) for stopping the running of the sheet material fed out. The drawer section supports the chuck section so as to be able to reciprocate, and the chuck section releases the sheet material after cutting the sheet material and returns toward the supply section.

[0007] Since the roll has a relatively large mass, rotating the roll itself at a high speed is not advantageous because the power of the roll drive system must be increased. It is desirable that the speed at which the sheet material is pulled out by the sheet material drawing section (75) is increased from the viewpoint of shortening the operation pitch for processing the drawn sheet material (improving the processing speed). Such a difference between the feeding of the sheet material and the drawing speed is absorbed by the upward movement of the tension rollers (703 to 705) when the sheet material is drawn. Thus, when the sheet material is pulled out at a high speed, the pulling force does not directly apply a rotating force to the roll, and when the sheet material is pulled out at a high speed, an excessive force is not applied to the sheet material supply portion, and the sheet material is removed. It can be fed out stably and at high speed. Further, it is not necessary to drive the feeding roller at a speed corresponding to the sheet material drawing speed or to rotate the roll at a high speed, and it is possible to reduce the size or the power of the power supply system for feeding the sheet material in the sheet material supply section (70). Power consumption can be reduced.

The tension roller (703 to 7) displaced by the high speed drawing of the sheet material by the drawing section.
The rotation stop of the feeding rollers (706, 707) can be controlled in synchronization with the return operation to the initial position of (0). That is, the operation of the feeding roller is stopped in response to the return of the tension roller to the initial position from the side closer to the leading end of the sheet material, and finally, the tension roller (703) adjacent to the roll returns to the initial position. The rotation of the roll (70) is stopped accordingly. As a result, the position of the tension roller before the sheet material is pulled out is always kept in the same state, whereby the sheet material drawing-out margin is always kept constant, and the possibility of obstructing high-speed sheet material drawing out is prevented. Can be. Conversely, if the positions of the plurality of tension rollers are different each time before the start of the sheet material withdrawal, it is expected that all the tension rollers reach the upper limit during the movement of the sheet material by the drawer. When such a situation occurs,
It is expected that an unreasonable force acts on the sheet material during the drawing, and the sheet material is undesirably cut or torn. Such a situation is prevented beforehand in the sheet material supply device.

Since the leading end position of the sheet material on the feeding side after being cut is controlled to be constant by the braking action of the braking means, the sheet material is always reliably held by the chuck portion.

[0010] Further, when the base end side of the sheet material pulled out by the drawer portion holding the leading end is cut by the cutter,
By providing the suction portion (77) for removing and sucking the rear end of the cut and separated sheet material, it is possible to suppress the state where the rear end of the cut sheet material floats and the position thereof is uncertain. This facilitates handling of the pulled-out and cut paper.

Further, a pair of structures for feeding the sheet material, braking the sheet material, and cutting the sheet material by the supply unit (70) are provided on the left and right sides of the frame (FRM4), and a cutter included in each structure is provided. The frame can be arranged on the base (732) so as to face the front of the sheet material drawer (75) alternately. This allows
When one of them is operating, the other can complete the installation of the roll in advance for the next operation, and can immediately switch to the other configuration when the roll is exhausted. In addition, the sheet supply operation does not need to be interrupted for the roll replacement, and in this regard, the supply efficiency of the sheet can be improved.

The stacked siding materials MS on the mounting arm are pushed from behind by the back stopper 82, and the stacked siding materials MS are pushed toward the packing unit 9.

<< Stacking Control >> The contents of the stacking control will be described with reference to FIG. FIG. 8A schematically shows processing contents when the siding material is conveyed by the roller conveyor 11 with the decorative surface facing downward, and FIG. 8B shows the processing content with the decorative surface facing upward. The processing contents when the siding material is conveyed by the roller conveyor 11 are schematically shown. Although not particularly limited, in the example of FIG. 8, it is assumed that the stacking number is set to six by the operation unit OPR. This causes the control unit CONT1 to:
The same control is repeated for each of the six siding materials. The desired number of stacked sheets can be arbitrarily set within an allowable limit.

First, a case where six siding materials MS1 to MS6 are conveyed with the decorative surface facing downward will be described. When the control unit CONT1 detects that the first siding material MS1 is conveyed by the roller conveyor 11 via the sensor S1, the control unit CONT1 detects the siding material MS1.
Is placed on the belt conveyor unit 2 and transported, and the reversing unit 3 and the superimposing unit 4 are set in a non-operating state, and the siding material MS1 is sent to the rotary stocker 5 as it is. The control unit CONT1 counts the number of siding materials based on the output of the sensor S1, and performs control according to the counted value.

When the first siding material MS1 is detected by the sensor S4, the control unit CONT1 advances the rotating stocker 5 by one pitch, and transfers the received siding material MS1 to the pair of rods 53A and 53B. And transport it.

When the control unit CONT1 detects via the sensor S1 that the second siding material MS2 has been conveyed by the roller conveyor 11, the control unit CONT1 places the siding material MS2 on the belt conveyor unit 2 and conveys it. During the transfer, the siding material M is output by the output of the sensor S2.
When S2 is detected, the siding material MS2 is reversed by the reversing unit 3. And control unit CON
When T1 detects the siding material MS2 based on the output of the sensor S3, the overlapping unit 4 lifts the siding material MS2 with the lifter 40 and holds the siding material MS2 with the vacuum holding unit 41.

Next, when the sensor S1 detects that the third siding material MS3 has been conveyed, the control unit C
The ONT 1 transports the siding material MS3 placed on the belt conveyor unit 2 and makes the reversing unit 3 inoperative, and the sensor S3 detects the siding material MS3.
In synchronization with the detection of the third siding material MS2, the second siding material MS2 held in the
The siding materials MS2 and MS3 are stacked on the second siding material MS3, and the rotary stocker 5 is fed in a state where two siding materials MS2 and MS3 are stacked. Second and third siding material M
When S2 and MS3 are detected by the sensor S4, the control unit CO
NT1 moves the rotating stocker 5 forward by one pitch, and transfers the received siding materials MS2 and MS3 to a pair of rods 5.
It is placed between 3A and 53B and transported.

The fourth siding material MS4 is processed under the same control as that of the second sheet, and the fifth siding material MS5 is processed under the same control as that of the third sheet.

When the sensor S1 detects that the sixth siding material MS6 has been conveyed, the controller CONT
1 carries the siding material MS6 on the belt conveyor unit 2 and conveys it. When the siding material MS6 is detected via the sensor S2 during the conveyance, the reversing unit 3 reverses the siding material MS6,
The siding material MS6 is fed into the rotating stocker 5 while the superimposing unit 4 is in a non-operating state. When the sixth siding material MS6 is detected by the sensor S4,
The control unit CONT1 advances the rotating stocker 5 by one pitch, and places and conveys the received siding material MS6 between the pair of rods 53A and 53B.

The control for every six siding materials is repeated, and the siding materials are sequentially conveyed by the rotating stocker 5 and when the siding materials are detected by the sensor S5, the control unit C
Each time the ONT 1 advances the pushing arm 54 to push out the siding material from between the pair of rods 53A and 53B.

When the control unit CONT2 detects the extrusion of the siding material via the sensor S6, it starts moving the front stopper 61 upward. The front stopper 61 reaches above the transport surface after the siding material is passed by the pushing arm 54. After detecting the completion of the elevation of the front stopper 61 by the sensor S7, the control unit CONT1 returns the pushing arm 54 to the return position, whereby the siding material is delivered from the pushing arm 54 to the stacking unit 6.

When the control unit CONT2 detects that the siding material has reached the stacking unit 6 based on the output of the sensor S8, it gives an instruction to the paper supply unit 7 and places it on the siding material that has reached this time. The operation of covering the paper is performed. In FIG. 8A, IP1 is a paper covered on the siding material MS1 in the course of stacking, IP2 is a paper covered on the siding material MS3, and IP3 is a paper covered on the siding material MS5. is there.

For the operation of covering the paper, it is possible to spend twice the time interval (transport pitch) in which the siding material is supplied to the roller conveyor unit 1 in series.
Compared with the operation of stacking the siding materials one by one and covering the paper, the conveyance speed of the siding material supplied from the roller conveyor unit 1 can be increased, and the siding material can be stacked by covering the decorative surface with the paper. The processing efficiency of stacking can be improved. Naturally, the number of operations for covering the paper can be reduced.

The control unit CONT2 counts the number of times the siding material has reached the stacking unit 6 based on the output of the sensor S8. According to this example, the number of stacked sheets is set to six. Accordingly, the control unit CONT
2 detects the state in which the siding material has reached four times (the state in which six siding materials are stacked) based on the output of the sensor S8, lowers the stopper 62 and lowers the mounting table 60. Then, the stacked siding material is transferred onto the slide arm 81 in the stacked state, and the slide arm 81 is advanced and then lowered, and the siding material on the slide arm 81 is now stacked in a stacked state. It is transferred to the transfer arm 80 as it is. Then, the control unit CONT2 advances the transfer arm 80, and after the transfer arm 80 passes over the back stopper 82, the back stopper 82 is moved to the cylinder block 820.
The siding material on the transfer arm 80 is pushed forward by the back stopper 82 in the stacked state, and the siding material is delivered to the cardboard box of the packing unit 9 in the stacked state.

As shown in FIG. 8B, when the siding materials MS11 to MS16 are supplied to the roller conveyor unit 1 with the decorative surface facing upward, the odd-numbered siding materials are removed by the reversing unit 3. The non-inverted second siding material MS12 is stacked on the inverted and inverted third siding material MS13, and the four non-inverted siding materials MS15 are inverted on the inverted fifth siding material MS15. The eye siding material MS14 is overlaid.
The overlapping process is not performed on the first and last siding materials MS11 and MS16 as described above. In FIG. 8B, IP11 is paper covered on the siding material MS11 during stacking, IP12 is paper covered on the siding material MS13, and IP13 is paper covered on the siding material MS15. is there.

<< Another Stacking Form >> The mechanism for transferring the siding material conveyed through the overlapping unit 4 to the stacking unit 6 is not limited to the configuration of the rotary stocker 5, and may be horizontally moved or It is possible to replace the transporting means with horizontal and vertical movement. FIG. 9 shows an example thereof together with a stacking mode.

According to the example of FIG. 9, the siding material conveyed by the belt conveyor unit 2 is placed on the pushing arm 54A and supplied to the stacking unit 6. The pushing arm 54A is a horizontal transfer mechanism similar to the pushing arm 54. When the mechanism of the push-out arm 54A is used, the siding material is not turned upside down in the middle like the rotary stocker 5, so that the reversing unit 3 and the superimposing unit 4 must be controlled in consideration of the fact. . When the rotating stocker 5 is not used, FIG. 9A showing a stacking mode in a case where the siding material is supplied from the roller conveyor unit 1 with the decorative surface facing down is different from FIG. Siding material MS1
And the process for the siding material MS6 are switched. FIG. 9B shows a stacking mode when the siding material is supplied from the roller conveyor unit 1 with the decorative surface facing upward.
(B), the processing for the siding material MS11 and the processing for the siding material MS16 are controlled to be switched.

FIG. 8 shows a siding material stacking configuration.
As described with reference to FIG. 9, the siding material on the bottom of the stack is controlled to face upward (the bottom face is a non-decorative face), and the top siding material is controlled to face downward (the top face is a decorative face). Depending on the structure of the corrugated cardboard to be used, it is also possible to adopt a cardboard stacking configuration in which only the two-layered siding materials whose anti-decorated surfaces are abutted to each other are sequentially stacked. For example, FIG. 10 shows a case in which a stacking device having a structure using a rotating stocker 5 is used, and the stacking mode of FIG. 10A receives four siding materials MS1 to MS4 with the decorative surface facing downward. This is a case of stacking, which is the same as the processing for the siding materials MS2 to MS5 in FIG. In addition, the stacking configuration in FIG. 10B has the decorative surface facing upward.
This is a case where the siding materials M11 to MS14 are received and stacked, and this is the same as the processing for the siding materials MS12 to MS15 in FIG.

FIG. 11 shows a case where a stacking device similar to the above, in which only two stacked siding materials whose opposite decorative surfaces are abutted to each other, is stacked in a stacking device employing the slide arm 54A. As shown, the inversion and superposition control modes are the same as those in FIG.

<< Paper Supply Unit >> Next, a detailed example of the paper supply unit 7 will be described. FIG. 2 shows the paper supply unit 7
It is a front view which shows the whole. The paper supply unit 7 includes a paper supply unit 70, a paper drawer 75, and a paper suction unit 77. The paper drawer 75 is disposed so as to straddle the stacking unit 6.

FIG. 3 is a side view of the paper supply unit 70, FIG. 4 is a front view of the paper supply unit 70, and FIG. 5 is a side view of the paper suction unit 77.

In FIG. 3, reference numeral 700 denotes a holder for exchangeably mounting a roll 701 in which paper is wound around a core material, and is rotatably driven by a motor 702 via a chain or the like. 70
Reference numerals 3, 704 and 705 denote tension rollers.
Reference numerals 6 and 707 denote feeding rollers driven by motors 706M and 707M. Each tension roller 703-
705 is a roller holder 70 as illustrated in FIG.
7, the roller holder 707 is slidably fitted on a guide rod 708 suspended from the frame FRM4.
3 to 705 can freely move up and down along the guide rod 708. The sensor S9 gives an analog signal corresponding to the distance from the tension roller 703 to the control unit CONT2.
For example, an ultrasonic sensor can be used as the sensor S9. The sensors S10 and S11 detect whether or not the tension rollers 704 and 705 are at the lower limit position, and provide a detection signal to the control unit CONT2. Roll 70
1 is wound around a tension roller 703, a feeding roller 706, a tension roller 704, a feeding roller 707, and a tension roller 705 in this order.
The sheet is fed forward by the rotation of the feed rollers 706 and 707. At this time, tension rollers 703-
Since the sheet 705 attempts to descend by its own weight, the sheet does not substantially loosen during the sheet feeding and during the sheet feeding stop state.

In FIG. 3, reference numeral 710 denotes a braked roller which has a built-in electromagnetic brake and is supported by a frame FRM4, and sandwiches the paper between the roller and a pressing roller 711. When the braked roller 710 is braked by the electromagnetic brake, the paper is pressed and fixed between the brake roller 710 and the pressing roller 711 to prevent the paper from being pulled out. In a state where the electromagnetic brake is not operated, the braked roller 710 rotates freely and allows the paper to be drawn forward.

A cutter roller 720 and its receiving roller 721 are disposed in front of the braked roller 710. A cutting blade 722 is provided on the surface of the cutter roller 720 along the axial direction thereof. As shown in FIG. 4, the same spur gear meshing with each other is fixed to the cutter roller 720 and the receiving roller 721, and when the cutter roller 720 rotates, the receiving roller 721 also rotates. The torque of a motor 724 can be transmitted to the cutter roller 720 via an electromagnetic clutch 723. The power transmission from the motor 724 to the electromagnetic clutch 723 and the power transmission from the electromagnetic clutch 723 to the cutter roller 720 may employ a chain transmission or the like. The cutter roller 720 is provided with a detection mark (detection target) 725 by the photo sensor 726, and a detection signal by the photo sensor 726 is given to the control unit CONT2. The control unit CONT2 rotates the cutter roller 720 with the electromagnetic clutch 723, and then controls the photo sensor 72.
6, the electromagnetic clutch 723 is disengaged, whereby the cutter roller 720 makes one rotation and stops at the initial position. The electromagnetic clutch 723 has a brake for braking the output shaft when power transmission is cut off, so that the cutter roller 720 does not rotate excessively due to inertia.

As shown in FIG. 4, a pair of left and right components for feeding the paper, braking the paper, and cutting the paper are provided on the frame FRM4. Frame F
As shown in FIG. 3, the RM 4 has sliders 730 and 731 on the left and right sides of the bottom surface thereof.
31 is mounted on a pair of guide rails 733 and 734 provided on a base 732. Further, as illustrated in FIG. 4, a lead screw shaft 736 rotationally driven by a motor 735 is disposed on the base 732, and a lead nut 737 screw-fitted to the lead screw shaft 736 is fixed to the bottom surface of the frame FRM4. Have been. As a result, the frame FRM4 is connected to the guide rails 733 and
The pair of left and right structures for feeding out the paper, braking the paper, and cutting the paper can alternately face the front of the paper drawer 75. Therefore, when one of the rolls is operated, the other can complete the mounting of the roll in advance in preparation for the next operation, and when the roll is exhausted, switch to the other configuration immediately. Therefore, it is not necessary to interrupt the stacking work or the like for the roll exchange, and the working efficiency can be improved.

As shown in FIG. 2, the paper drawer 75 has an arch-shaped frame FRM5 which is arranged so as to straddle the stacking unit 6.
A guide rail 750 is provided from one end to the other end, and a drive belt 751 is stretched along a drive pulley 752 and an idle pulley 753 along the guide rail 750.
The drive pulley 752 is driven by a motor 754 having a built-in electromagnetic brake. The guide rail 750 is provided with a holder 755 which is fitted to the guide rail 750 and is slidable. The holder 755 detachably holds the leading end of the paper projecting from between the cutter roller 720 and the receiving roller 721. The chuck portion 756 to be attached is vertically fixed.
The chuck portion 756 includes, but is not limited to, a pair of holding plates 756A and 756B that contact and separate using compressed air. The holding plates 756A and 756B can be connected and separated by an air cylinder 756C that operates with compressed air. Can be adopted. The holder 755 is connected and fixed to the drive belt 751 and travels integrally with the drive belt 751, whereby the chuck portion 756 clamps the paper and then drives the drive belt 751 to travel, thereby driving the paper. The paper can be put on the siding material placed on the placing table 60 of the stacking unit 6 by being pulled out from the supply unit 70.

The amount of paper drawn by the paper drawer 75 is determined by the amount of travel of the chuck 756,
The travel distance is controlled by the control unit CONT2. That is, when the length of the siding material to be processed is set in the operation unit OPR, the control unit CONT2 refers to the set value, calculates the traveling amount of the chuck unit 756 from the initial position, and calculates the travel amount of the motor 754. The amount of rotation is controlled, and the traveling movement of the chuck unit 756 is stopped at a position slightly advanced from the far end of the siding material placed on the placing table. After stopping the motor 754, the control unit CONT2 releases the paper from the chuck unit 756, and reverses the motor to return the chuck unit 756 to the initial position.

The paper suction unit 77 is configured such that when the chuck unit 756 cuts the base end side of the paper that has been pulled out with the front end held by the cutter roller 720, the rear end of the cut and separated paper floats to the position. Is suppressed from becoming unstable. That is, as shown in a detailed example in FIG. 5, the paper suction section 77 includes a suction block 770 and a sweeping-off lever section 771 provided on a frame FRM6.
The suction block 770 has a large number of air suction holes on its upper surface, and is disposed immediately below the paper running surface pulled out by the chuck unit 756. The sweeping-off lever portion 771 is an actuator using air pressure, and a 90 ° reciprocating rotation type air rotor is disposed on a reciprocating linear movement type piston rod, and the rotation shaft of the air rotor is provided as an operating end 722. The operating end 722 is provided with a rotating lever 773. When the chuck portion 756 is at the initial position in FIG. 2, the rotating lever 773 is oriented upward, and is oriented so as not to obstruct the paper drawing. After the feeding of the paper is started, the rotation lever 733 is brought into a horizontal state immediately above the surface of the paper at the timing when the chuck unit 756 passes through the paper suction unit 77. Then, at a timing synchronized with the cutting of the paper, the rotating lever 773 is lowered and the suction block 7 is moved.
The suction operation of the paper 70 is started, whereby the rear end of the cut paper is wiped downward by the rotating lever 773, and the rear end of the paper that has been cut off is sucked by the suction block 770.
Is absorbed by air. After the trailing end of the cut paper is settled, the rotating lever 773 is returned to the initial upward state, and the suction operation of the suction block 770 is stopped.

<< Paper Supply Control >> Next, the control unit CONT2
Will be described with reference to FIG. In FIG. 1, DT1 to DT6 are detection signals supplied from various sensors S8 to S12, 726, CN
1 to CN9 are 1-bit or multiple-bit control signals output from the control unit CONT2.

The initial position of the chuck portion 756 and the initial leading edge position of the paper are the positions at time t0 in FIG. In this state, the rotation of the motors 702, 706M, and 707M is stopped, the electromagnetic clutch 723 is in the power non-transmission state, and the electromagnetic brake of the braked roller 710 is in the released state. The chuck unit 756 is on standby while holding the leading end of the paper fed from the paper supply unit.

In this state, when the control unit CONT2 receives the detection signal DT5 of the siding material MS from the sensor S8, it drives the motor 754 with the control signal CN3 to drive the chuck unit 756 to drive out the paper IP to draw out the paper IP. Start. In synchronization with this, the control unit CONT2 outputs the control signal C
The motor 707M is driven by N6, and the feeding of the paper is started in response to the drawing of the paper by the chuck unit 756.
The control unit CONT2 preliminarily rotates the rotation lever 773 from the vertical state to the horizontal state at the timing when the chuck unit 756 passes the sweeping-off lever unit 771, and immediately rotates the paper when the paper is cut, which will be described later. To be able to pay off.

The speed at which the paper supply unit 70 feeds out the paper IP is slower than the speed at which the paper drawer 75 draws out the paper IP.
Gradually rises, and then the tension roller 704 starts to rise. When the sensor S10 detects this, the control unit CONT2 starts driving the motor 706M with the control signal CN7. At this time, the control unit CONT2
02, and the paper IP is fed from the roll 701 by controlling the rotation speed of the motor 702 at a speed proportional to the ascending position of the tension roller 703 based on the detection signal DT4 from the ultrasonic sensor S9.

Here, the roll 701 has a relatively large mass, the load driving capability of the motor 702 is relatively small from the viewpoint of economy, and the rotation speed of the roll is relatively low. Roller 706 by motor 706M
, And the rotation speed of the roller 707 by the motor 707M is made faster than that of the roller 706. As the paper IP is closer to the drawing side, the feeding speed of the paper IP is increased. The speed at which the paper IP is drawn while traveling while being clamped by the chuck portion 756 is set to be extremely high. The difference in the paper transport speed in each section is absorbed by the upward movement of the tension rollers 703 to 705. Therefore, it is not necessary to drive the motors 702, 706, and 707 at the same speed as the paper drawing speed to feed the paper, and to reduce the size of the power system for feeding the paper represented by the motor 702 or to reduce the power. Power consumption can be reduced.

The driving amount of the motor 754 (the chuck portion 756)
Is controlled numerically by the control unit CONT2. For example, a step motor is adopted for the motor 754, and the control unit CONT2 controls the motor 75 to obtain a necessary traveling amount.
The number of driving steps of 4 is counted, and the motor 754 is driven until the number reaches the target value. The target value is acquired by the control unit CONT2 by calculation or referring to a table based on the length data of the siding material set by the operation unit OPR. In the drive control of the motor 754, it is possible to decelerate near the stop position. Further, the motor 756 is braked when its rotation stops.

The control unit CONT2 connects the electromagnetic clutch 723 by the control signal CN5 and rotates the cutter roller 720 at the point of time t1 before the stop position of the chuck unit 756 shown at time t2. The paper is cut when the cutter roller 720 is rotated approximately half a turn. At this time, the control unit CONT2 controls the rotation lever 7 by the control signal CN2.
At the same time, the suction block 770 starts the suction operation by the control signal CN1. As a result, the rear end of the cut and separated paper passes over the suction block 770 so as to be attracted to the suction block 770. When the sensor 726 detects that the cutter roller 720 makes one rotation, the controller CONT2 stops the cutter roller 720 at the original position.

The cut and separated paper IP is transported by the chuck unit 756 until time t2, and thereafter the control unit CONT2
Releases the paper from the chuck portion 756 by the control signal CN9, and the paper cut and separated by the
It is surely dropped on S. Thereafter, the motor 754 is driven to rotate in the reverse direction, and the chuck 756 is returned to the initial position.

Even if the paper IP is cut by the cutter roller 720, the feeding of the paper IP is continued due to the inertia of the operation of the paper supply unit 70. The control unit CONT2 controls the electromagnetic force of the braked roller 710 by the control signal CN4 after a predetermined delay time from the rotation instruction to the cutter roller 720 so as to stop the leading end of the cut-out sheet at the feeding side at the initial position. Activate the brake to activate the roller 710
Brake.

As a result, when the leading end of the paper IP is stopped, the tension roller 705 moves down. When the sensor S11 detects the lower limit position, the control unit CONT
2 stops the motor 707M by the control signal CN6. When the motor 707M is stopped, the tension roller 704 descends, and when the sensor S10 detects the lower limit position, the control unit CONT2 stops the motor 706M with the control signal CN7. Then, the tension roller 703 descends, and the control unit CONT2 receiving the detection signal DT4 corresponding to the descending amount gradually decelerates the motor 702, and the motor 702 moves to the lower limit position of the tension roller 703.
Will be stopped. As a result, the state of the paper supply unit is returned to the initial state, and the control unit CONT2 holds the leading end of the paper with the chuck unit 756 and waits for an instruction for the next paper drawing operation.

As shown in FIG. 4, the above-described control of switching between the left and right components for feeding the paper, braking the paper, and cutting the paper is not particularly limited, but is performed based on the detection of the remaining amount of the roll 701. . For example, a predetermined marking is given to the end portion of the paper IP wound on the roll 701, and when the sensor S12 detects this, the control unit CONT2
After the paper is cut by the cutter roller 720, the motor 735 is cut.
To swap the left and right configurations. After the replacement, the control unit CONT2 holds the leading end of the replaced paper by the chuck unit 756 to prepare for the next operation.

According to the above stacking device, the following operation and effect can be obtained.

[1] The two siding materials MS are stacked via the reversing unit 3 and the overlapping unit 4 with the surfaces opposite to the decorative surface facing each other, and the siding material is sequentially passed to the stacking unit 6. The operation of covering the upper surface (decorative surface) of the siding material transferred to the stacking unit 6 with the paper IP is twice the time interval (transport pitch) in which the siding material is supplied to the belt conveyor unit 2 in series. You can spend time. Therefore, as compared with a configuration in which the siding materials are stacked one by one and the paper is covered each time, the number of operations for covering the paper can be reduced, and the transport speed of the siding material MS in the belt conveyor unit 2 is increased. Therefore, the processing efficiency of stacking the siding material with the paper interposed between the decorative surfaces can be improved.

[2] The paper supply unit 7
Supply unit 70 that feeds paper from paper feeder, and paper IP that is fed
And a paper drawer 75 for holding the leading end of the paper at a high speed and pulling out the paper at a high speed.
Roller 7 for feeding paper IP from roll 701 through
06, 707, the paper IP is cut by a cutter roller 720 in a state where the fed paper IP is nipped by a chuck portion 756 of a paper drawer 75 and pulled out at high speed, and after cutting, the paper IP is moved forward from the cutter roller 720. The travel of the paper IP to be traveled is braked by the braked roller 710. At this time, since the roll 701 has a relatively large mass, the feeding speed of the paper fed from the roll via the feeding roller is relatively low. The speed at which the paper IP is pulled out by the paper drawer 75 is significantly higher than the paper feeding speed from the viewpoint of improving the operation speed of the entire stacking device. Such a difference in the paper conveyance speed is absorbed by the upward movement of the tension rollers 703 to 705. Therefore, the paper IP is stored in the chuck 7
When the paper IP is pulled out at high speed, the pulling force is not directly transmitted to the roll 701, so that no excessive force is applied to the paper supply unit 70 when the paper IP is pulled out, and the paper IP is fed out stably and at high speed. Can be. In addition, it is not necessary to drive the paper feed roller or rotate the roll at a speed corresponding to the paper drawing speed, so that the power supply system for feeding the paper in the paper supply unit 70 can be reduced in size or reduced in power consumption. can do.

[3] As described above, stable and high-speed supply of the paper IP by the paper supply unit 7 is realized.
It is possible to guarantee a high stacking operation speed of the siding material within a range permitted by the operation speed.

[4] In particular, the tension roller 70 displaced by the high-speed drawing of the paper by the paper drawer 75
Reference numerals 3 to 705 do not adopt a configuration in which the tension rollers 703 to 705 return to the initial position from the side closer to the leading end of the paper IP at which the paper IP is fed, irrespective of the operation of the feeding rollers 706 and 707. Then, the operation of the feeding rollers 706 and 707 is stopped, and finally the tension roller 7 adjacent to the roll 201 is stopped.
Since the rotation of the roll 701 is stopped in response to the return of the initial position of the paper IP 03, the tension roller 703 before the paper IP is pulled out.
The positions of .about.705 are always kept in the same state, so that the paper IP withdrawal allowance is always kept constant, and the risk of obstructing the high-speed paper withdrawal can be prevented. Conversely, if the positions of the plurality of tension rollers 703 to 705 before the start of the paper drawing are different each time, all the tension rollers 703 to 705 are set to the upper limit while the paper is running by the chuck unit 756. When such a situation occurs, an excessive force acts on the paper during drawing, and it is expected that the paper is undesirably cut or torn. In the paper supply unit 70, such a situation is prevented from occurring.

[5] Since the leading end position of the paper on the feeding side after being cut is also controlled to be constant by the braking action of the braked roller 710, the gripping of the paper by the chuck portion can always be ensured. .

[6] The paper supply unit 7 further removes the trailing end of the cut and separated paper when the chuck portion 756 cuts the base end side of the paper IP pulled out with the front end held by the cutter roller 720. Since the paper suction unit 77 for dropping and sucking the paper IP is provided, it is possible to suppress a state where the rear end of the cut paper IP floats and the position of the paper IP becomes unstable.
The paper IP can be reliably covered on the siding material MS of the stacking unit 6.

[7] A pair of left and right components for feeding the paper, braking the paper, and cutting the paper are provided on the left and right sides of the frame FRM4, and the cutter rollers included in each configuration are alternately provided in the paper drawer 75. To the front of the building. Therefore, when one of the components is operated on the other, the mounting of the roll can be completed in advance for the next operation on the other side, and when the roll is used up,
Since it is possible to immediately switch to the other configuration, it is not necessary to interrupt the stacking work or the like for the roll exchange, and the stacking work efficiency can be improved also in this regard.

Although the invention made by the inventor has been specifically described based on the embodiment, it is needless to say that the present invention is not limited to the embodiment and can be variously modified without departing from the gist of the invention. No.

For example, the number of tension rollers and the number of feed rollers in the paper supply unit are not limited to the above examples, but can be changed as appropriate according to the allowable maximum drawing length of paper. Further, the sheet material is not limited to paper, but may be a resin film or the like. Further, the sheet material supply device according to the present invention is not limited to the case where the sheet material supply device is applied to a siding material stacking device, but can be widely applied to an effective device or system that receives supply of cut sheet material.

[0084]

According to the present invention, a sheet material is fed out from a roll through a plurality of tension rollers and a feeding roller, and the leading end of the fed sheet material is clamped above the plate stacked on the stacking means. The sheet material is pulled out while traveling, the sheet material being drawn is cut at a predetermined position, and the sheet material feeding device is configured to brake the sheet material fed after cutting, so that the sheet material can be moved from a roll having a large mass. The difference between the speed at which the sheet material is fed out and the speed at which the fed sheet material is pulled out at a high speed can be absorbed by the upward movement of the tension roller when the sheet material is pulled out, so that when the sheet material is pulled out at a high speed. However, the pulling force does not directly apply a rotating force to the roll. Excessive force is not applied to the part, the sheet material can be fed out stably and rapidly, moreover,
There is no need to drive the feed roller or rotate the roll at high speed at a speed equivalent to the sheet material withdrawal speed.
The power system for feeding the sheet material in the sheet material supply means can be reduced in size or reduced in power consumption.

By stopping and controlling the feed roller in synchronization with the returning operation of the tension roller to the initial position, which is displaced by the high speed drawing of the sheet material by the drawing section, the position of the tension roller before the sheet material is drawn is always maintained. The same state is maintained, so that the sheet material withdrawal allowance is always kept constant, and the possibility of obstructing the high-speed sheet material withdrawal can be prevented.

Since the leading end position of the sheet material on the feeding side after being cut is controlled to be constant by the braking action of the brake means, the chucking of the sheet material by the chuck portion can always be performed reliably.

Further, when the base end side of the sheet material pulled out by holding the leading end by the drawer section is cut by the cutter,
By providing a suction unit that wipes off the rear end of the cut and separated sheet material and suctions it, it is possible to suppress the state where the rear end of the cut sheet material floats and the position becomes unstable, thereby In addition, the handling of the pulled-out and cut paper becomes easy.

Further, a pair of structures for feeding the sheet material, braking the sheet material, and cutting the sheet material by the supply unit are provided on the left and right sides of the frame, and the cutters included in the respective structures are alternately provided with the sheet material drawing unit. By arranging the frame on the base so as to face the front of the sheet, it is not necessary to interrupt the sheet material supply operation for the roll exchange, and in this respect, it is possible to improve the sheet material supply efficiency. Can be.
