Meanwhile, as shown in FIGS. 5 and 6, the cutter 58 moves horizontally from the left to the right in the cylindrical cutting spaces 98 and 99 surrounded by the cutter moving groove 28 and the lower moving groove 96.

(8-2) Control Method of Cylinder Device Next, a structure for moving the cutter 58 at high speed using the rodless cylinder 48 of the cylinder device will be described with reference to FIGS. The cylinder device of the cutting device 46 includes a rodless cylinder 48, a pump 160 such as a compressor for feeding compressed air, a first electromagnetic valve 170, and a second electromagnetic valve 180.

  As shown in FIGS. 29 to 31, the cylinder main body 90 of the rodless cylinder 48 has a cylindrical shape, and a piston 190 is movably disposed therein. A first cylinder port 191 is provided at one end of the cylinder body 90, and a second cylinder port 192 is provided at the other end. A slit 193 is provided on the upper surface of the cylinder body 90 along the longitudinal direction, that is, the moving direction of the piston 190. The piston 190 is provided with a cutter support portion 88 through the gap of the slit 193. The cutter support portion 88 is provided with an upper seal belt 194 that closes the slit 193 and a lower seal belt 195 disposed below the upper seal belt 194. A belt separating unit 196 that separates the upper seal belt 194 and the lower seal belt 195 is provided inside the cutter support unit 88. The upper seal belt 194 is attached to the other end portion of the slit 193 from one end portion of the slit 193 provided on the upper surface of the cylinder body 90 through the belt separating portion 196 inside the cutter support portion 88. The lower seal belt 195 is also fixed to one end portion of the slit 193, passes below the belt separating portion 196 provided in the cutter support portion 88, and is attached to the other end portion of the slit 193. The slit 193 is closed by the upper seal belt 194 and the lower seal belt 195, and the cylinder body 90 becomes a closed space. Further, the cutter support part 88 moves along the slit 193 by sewing between the upper seal belt 194 and the lower seal belt 195 disposed above and below the belt separation part 196. In the following description, the closed space between the first cylinder port 191 and the piston 190 is referred to as “first closed space 197”, and the closed space between the piston 190 and the second cylinder port 192 is referred to as “second closed space 198”. Call it.

  As shown in FIGS. 29 to 31, the first electromagnetic valve 170 uses three ports in the five-way valve, the first connection port 171 is connected to the pump 160, and the second connection port 172 is Are connected to the first cylinder port 191, and the third connection port 173 is connected to the second electromagnetic valve 180. Connection ports that are not being used are blocked.

  As shown in FIGS. 29 to 31, the second solenoid valve 180 uses three ports in the five-way valve, and the fourth connection port 181 that is the first connection port is the first solenoid valve 170. The fifth connection port 182 that is the second connection port is connected to the second cylinder port 192 of the cylinder body 90, and the sixth connection port 183 that is the third connection port is , Open to the atmosphere. Connection ports that are not being used are blocked. The first to third connection ports of the second electromagnetic valve 180 are referred to as fourth, fifth, and sixth connection ports 181 to 183, respectively. This is because it is clearly distinguished from the connection ports 170 to 173.

  A method of moving the cutter 58 at a high speed will be described with reference to FIGS. First, the first cylinder port 191 side of the cylinder body 90 is a start position where the cutter 58 starts to move, and the second cylinder port 192 side is an end position where the cutting is finished. The 1st solenoid valve 170, the 2nd solenoid valve 180, and the pump 160 are controlled by the control apparatus 10 demonstrated later.

  As shown in FIG. 29, the first stage is a state where the cutter support portion 88 is waiting at the start position. In this state, the pump 160 operates, and the first solenoid valve 170 connects the first connection port 171 and the third connection port 173 to form a passage. Other connection ports are blocked. The second solenoid valve 180 connects the second cylinder port 192 and the opened sixth connection port to form a passage. In this state, the compressed air from the first electromagnetic valve 170 is stopped before the second electromagnetic valve 180. The pump 160 is sending compressed air. When the pressure of the compressed air exceeds a certain level, the pump 160 continues to operate while maintaining the pressure. On the other hand, the compressed air inside the second closed space 198 is exhausted from the second cylinder port 192 to the atmosphere via the sixth connection port 183. Therefore, the second closed space 198 becomes the same as the atmospheric pressure. As will be described in the third stage, compressed air is sent into the second closed space 198 when the piston 190 is returned when the cutter support portion 88 returns from the end position to the start position. Therefore, the pressure in the second closed space 198 is higher than atmospheric pressure, but since the compressed air is released from the second closed space 198 as described above, the inside of the second closed space 198 is in this first stage. It becomes atmospheric pressure.

  In the second stage, as shown in FIG. 30, the cutter 58 moves from the start position to the end position at a high speed and cuts the web. In this state, the pump 160 sends compressed air, and the first solenoid valve 170 connects the first connection port 171 and the second connection port 172 to form a passage. Other connection ports are blocked. For this reason, the compressed air from the pump 160 is sent to the first cylinder port 191 of the cylinder body 90. On the other hand, the second solenoid valve 180 connects the fifth connection port 182 and the sixth connection port 183 to form a passage as in the first stage. Other connection ports are blocked. In this state, compressed air is fed into the first closed space 197 and air in the second closed space 198 is exhausted, so that the piston 190 moves from the start position to the end position at a high speed, and the old web W1 and The new web W2 is cut at the same time in a stacked state. When the piston 190 reaches the end position, the air is exhausted from the second closed space 198 by the piston 190. Therefore, the flow rate of the exhausted air is adjusted by adjusting the width of the sixth connection port 183. Thus, the piston 190 is prevented from colliding with the second cylinder port 192 side. That is, as the exhaust flow rate of air is reduced, the air cushioning property by air is enhanced, and the air cushioning property is lowered as it is decreased. Therefore, the extent of the air cushion is confirmed by experiment, and the width of the sixth connection port 183 in the second electromagnetic valve 180 is set.

  As shown in FIG. 31, the third stage is a state in which the cutter support portion 88 at the end position returns to the start position. In this state, the first electromagnetic valve 170 connects the first connection port 171 and the third connection port 173 to form a passage, and sends compressed air from the pump 160 to the second electromagnetic valve 180. Other connection ports are blocked. The second solenoid valve 180 connects the fourth connection port 181 and the fifth connection port 182. Other connection ports are blocked. As a result, the compressed air from the pump 160 reaches the second electromagnetic valve 180 through the first electromagnetic valve 170 and is sent into the second closed space 198 from the second cylinder port 192, and the piston 190 returns from the end position to the start position. To do. Since the first cylinder port 191 is closed when the piston 190 reaches the start position, a certain amount of compressed air exists in the first closed space 197, and this serves as an air cushion. No collision with 1 cylinder port 191.

  As described above, the cutter 58 can move at a high speed when cutting, and does not collide with the second cylinder port 192.

(8-3) Operating State of Cutting Device 46 The operating state of the cutting device 46 will be described with reference to FIGS. 5 and 6.

Secure with pinching. At this time, the location where the old web W1 and the new web W2 are to be cut is located in the cutting spaces 98 and 99 surrounded by the cutter moving groove 28 and the lower moving groove 96.

  Next, when the air in the cutting space 98 is sucked from the upper dust suction port 104 and the air in the cutting space 99 is sucked from the lower dust suction port 106, the air flows from the left to the right as shown in FIG. Sucked into. This is because the left of the cutting spaces 98 and 99 is open.

  Next, when the cutter support portion 88 moves along the cylinder main body 90, the cutter 58 moves the passing slit 94 of the partition sheet 92 and cuts the stacked old web W1 and new web W2 in the width direction. The dust generated by the cutting is sucked by the dust suction unit 102 and does not adhere to the surfaces of the old web W1 and the new web W2.

  Next, when the cutter 58 finishes cutting the stacked old web W1 and new web W2, the suction of the dust suction unit 102 is stopped.

  As a result, the cutting device 46 finishes cutting without dust adhering to the surfaces of the old web W1 and the new web W2, and the connecting device 1 can move to the next step.

The other end of the second check valve 116 is connected to one end of the first connection pipe 124, and the other end of the first connection pipe 124 branches into six, and the branched other ends and six two-way valves 118- One end of each of 1-118-6 is connected. The air flow in the second check valve 116 is in the direction from the two-way valves 118-1 to 118-6 to the negative pressure pump 110. Negative pressure tanks 114-1 to 114-6 are connected to the other ends of the two-way valves 118-1 to 118-6, respectively.

  The second connection pipes 126-1 to 126-6 are connected to the suction parts of the first to sixth systems and the negative pressure tanks 114-1 to 114-6, respectively. Further, a suction two-way valve 120-1, a suction three-way valve 120-2 to 120-6, and pressure gauges 122-1 to 122-6 are provided between the second connection pipes 126-1 to 126-6, respectively. ing.

  In the initial state, the inside of the negative pressure tank 114-5 is lowered to the set negative pressure -P1 as described above. The suction three-way valve 120-5 has an inlet in a closed state and a first outlet and a second outlet in a conductive state. Therefore, the suction space 55 in the first lower suction part 54 is at atmospheric pressure because a plurality of small suction holes 457 and large suction holes 459 are opened.

  Then, the new web W2 closes the small suction hole 457 and the large suction hole 459 of the first lower suction part 54, and the suction space 55 of the first lower suction part 54 becomes a closed space.

  Next, when the inlet and the first outlet of the suction three-way valve 120-5 are brought into conduction and the second outlet is closed, the suction tank 55 between the negative pressure tank 114-5 and the suction space 55 of the first lower suction part 54 is used. The internal pressure of the negative pressure tank 114-5 and the internal pressure of the suction space 55 of the first lower suction part 54 are in an equilibrium state. That is, the internal pressure of the negative pressure tank 114 increases from the set negative pressure −P1 to −P4, and the internal pressure of the suction space 55 of the first lower suction portion 54 decreases from atmospheric pressure to −P4. As described above, when the internal pressure of the suction space 55 of the first lower suction portion 54 is lowered to −P4, the new web W2 can be sucked. This suction timing can be dealt with immediately by operating the suction three-way valve 120-5.

  Next, at the timing when the suction of the new web W2 ends, the suction of the first lower suction portion 54 is made by closing the inlet of the suction three-way valve 120-5 and making the first outlet and the second outlet conductive. The internal pressure of the space 55 rises to atmospheric pressure, and suction can be terminated.

  The operator passes the new web W2 over the lower main body 40 through the upper surface of the carry-in pressing roll 4 at the initial height, and attaches the front end of the new web W2 to the rear end portion of the upper and lower members 60 by the fixing member 66. At this time, since the lower main body 40 is at the initial height, the space between the lower main body 40 and the upper unit 12 is widened, and the operator can easily pass the new web W2 between the upper unit 12 and the lower main body 40.

  The operator sucks the non-contact surface of the upper tape 34 with the upper tape elastic plate 436 attached to the upper tape suction surface 35 of the upper tape attaching body 20 interposed therebetween.

  The operator sucks the non-adhesive surface of the lower tape 52 with the lower tape elastic plate 45 attached to the lower tape suction surface 53 of the lower tape attaching roll 42 interposed therebetween.

(16) Suction Step of Negative Pressure Device 150 and Suction Device 100 Next, in the negative pressure device 150 and the suction device 100, the step of the second lower suction portion 56 sucking the new web W2 will be described with reference to FIG. This will be described with reference to the flowchart of FIG.

  In step S1, the control device 10 closes the inlets of the suction two-way valve 120-1, all of the suction three-way valves 120-2 to 120-6, and puts the first outlet and the second outlet into a conductive state.

  In step S2, the control device 10 opens all the two-way valves 118-1 to 118-6, and proceeds to step S3.

  In step S <b> 3, the control device 10 slides the piston 130 of the negative pressure pump 110 by the power cylinder 112 to widen the first space 132 and lower the negative pressure tanks 114-1 to 114-6 by ΔP. Then, the process proceeds to step S4.

  In step S4, the control device 10 measures whether or not the inside of the negative pressure tanks 114-1 to 114-6 has reached the set negative pressure -P1 with the pressure gauges 122-1 to 122-6, and all the negative pressure tanks are measured. If the pressure in 114-1 to 114-6 has decreased to the set negative pressure −P 1, the process proceeds to step S 5 (in the case of y). If not decreased to the set negative pressure −P 1, the process returns to step S 3 Only lower again (in the case of n). For the negative pressure tank 114 that has decreased to the set negative pressure −P1 in the seven systems, only the two-way valve 118 connected to the negative pressure tank 114 is closed.

  In step S5, since all of the negative pressure tanks 114-1 to 114-6 are lowered to the set negative pressure -P1, the control device 10 closes all the two-way valves 118 and turns off the negative pressure pump 110. Stop. Then, the process proceeds to step S6.

  In step S6, the control device 10 sets the suction of all the suction units to a standby state, and proceeds to step S7.

In step S8, the control device 10 brings the inlet and the first outlet of the suction three-way valve 120-6 into a conductive state and closes the second outlet. Then, the internal pressure of the suction space 59 of the second lower suction part 56 is lowered to reach an equilibrium state, and the process proceeds to step S11. Assuming that the volume of the negative pressure tank 114 is V1, the set pressure is −P1, the volume of the suction space 59 of the second lower suction section 56 is V2, and the suction pressure is −P2, V1: V2 = | −P1 |: | −P2 | The suction pressure -P2 is a pressure when the suction three-way valve 120-6 is conducted and the internal pressures of the second lower suction part 56 and the negative pressure tank 114-6 are in an equilibrium state. However, the flow resistance factor is excluded. In step S9, since the internal pressure of the suction space 59 of the second lower suction portion 56 is lowered to -P2, the suction of the new web W2 can be executed, and the process proceeds to step S10.

  In step S10, the control device 10 instructs the end of the suction in the sixth step, and proceeds to step S11.

  In step S11, the control device 10 closes the inlet of the suction three-way valve 120-6 and brings the first outlet and the second outlet into a conductive state. As a result, the internal pressure of the suction space 59 of the second lower suction portion 56 increases to atmospheric pressure, and the process proceeds to step S12.

  In step S12, since the internal pressure of the suction space 59 of the second lower suction part 56 has become atmospheric pressure, the suction of the new web W2 is completed, and the process returns to step S2.

  Note that the operations of steps S6 to S12 are also performed in parallel at the suction start timing and the suction end timing for the suction portions of the system other than the second lower suction portion 56, respectively.

(17) Effects of the Invention According to the present embodiment, the rod 58 is provided with the first solenoid valve 170 and the second solenoid valve 180, and the cutter 58 moves at a high speed in order to control the state in which compressed air is sent. The old web W1 and the new web W2 can be cut. At this time, the piston 190 that moves the cutter support portion 88 does not collide with the second cylinder port 192 side. The cutter 58 can move at high speed because the piston 190 is supplied with compressed air from the first cylinder port 191 and the second closed space 198 is at atmospheric pressure. In addition, since the amount of air exhausted from the second cylinder port 192, the fifth connection port 182 and the sixth connection port 183 is small, the resistance when the air flows is small, and the cutter 58 can move more quickly.
