When the operator drives the third air cylinder 65, the piston of the third air cylinder 65 moves, and the pressing portion 64 moves upward. As shown in FIG. 7, the pressing portion 64 moved upward pushes up the sphere 43 upward. A gap is formed between the hole 44 of the bulb 40 and the sphere 43. The adhesive 55 flows downward through the flow path 41. The adhesive flows through the gap between the hole 44 and the sphere 43 and flows out of the cartridge 60 into the hole 63. The adhesive 55 flows into the supply path 81 connected to the hole 63.

  The adhesive supply path will be described with reference to FIGS.

  As shown in FIG. 8, the supply path 81 connected to the hole 63 is a through hole extending toward the pump case 14 at the lower end of the peripheral wall on the pump case 14 side. The supply path 81 is a path that guides the adhesive flowing out of the cartridge 60 to the gear pump 124.

  The supply path 81 extends from the storage chamber 18 to the center in the first pump case 31 of the pump case 14. The supply path 81 is bent at a right angle (on the back side in the drawing in FIG. 8) at the central portion of the first pump case 31 and reaches the upper end of the portion where the drive gear 122 and the driven gear 123 are engaged.

  As shown in FIG. 9, the supply path 82 is a path that guides the adhesive that has passed through the gear pump 124 to the supply path 83 of the support portion 16. The supply path 82 extends leftward from the lower end of the portion where the drive gear 122 and the driven gear 123 (see FIG. 8) mesh with each other. The supply path 82 extending to the left bends downward, bends to the left at the lower end, and passes through the shaft portion 45 to the supply path 83 in the support portion 16.

  The supply path 83 is a path that guides the adhesive flowing through the supply path 82 to the nozzle 17. The supply path 83 extends from the upper end 34 to the lower end 35 in the support portion 16 and reaches the supply path 84 in the nozzle 17.

  The supply path 84 is a path that guides the adhesive flowing through the supply path 83 to the discharge port 86. The discharge port 86 is provided below the left end of the nozzle 17. The supply path 84 extends from the right end to the left end in the nozzle 17 and is connected to the discharge port 86. The adhesive is discharged from the discharge port 86 to the outside.

  With reference to FIG.8 and FIG.9, the flow of the adhesive agent which reaches the discharge port 86 of the nozzle 17 from the storage chamber 18 via the pump case 14 and the support part 16 is demonstrated. The pressing portion 64 pushes up the sphere 43 upward, and the adhesive flows out of the cartridge 60. The adhesive that has flowed out flows to the gear pump 124 via the supply path 81. The first motor 91 drives the drive gear 122, and the drive gear 122 and the driven gear 123 rotate. The gear pump 124 sends out the liquid state adhesive from the supply path 81 toward the supply path 82. The adhesive flows from the supply path 82 toward the supply path 83, reaches the supply path 84, and is discharged to the outside from the discharge port 86.

  With reference to FIG. 10, the state of the bonding machine 2 at the time of bonding work for bonding the upper cloth 151 and the lower cloth 152 will be described.

  When performing the bonding operation, the bonding machine 2 moves the movable portion 75 (see FIG. 2) of the first air cylinder 24 (see FIG. 2) forward, and moves the support portion 16 to the use position. The operator arranges the upper cloth 151 and the lower cloth 152 so as to overlap each other. The operator places the nozzle 17 on the bonded portion of the cloth. The upper transfer roller 22 and the lower transfer roller 25 sandwich the upper cloth 151 and the lower cloth 152 behind the nozzle 17.

  When the operator steps on the pedal 208, the adhesive flows out of the cartridge 60. The adhesive that has flowed out passes through the supply path 81 and flows to the gear pump 124. The gear pump 124 is driven to feed the adhesive to the supply paths 82 to 84. The adhesive is discharged from the discharge port 86 of the nozzle 17. The adhesive discharged from the discharge port 86 adheres to the lower cloth 152. The upper transfer roller 22 and the lower transfer roller 25 rotate in a direction to transfer the upper cloth 151 and the lower cloth 152 from the front to the rear. The spring 21 urges the upper transfer roller 22 downward. Therefore, the upper transfer roller 22 and the lower transfer roller 25 press and bond the upper cloth 151 and the lower cloth 152.

  The electrical configuration of the cloth bonding apparatus 1 will be described with reference to FIG. The cloth bonding apparatus 1 includes a CPU 201, a ROM 202, a RAM 203, and a storage device 29. The CPU 201 executes reception processing and control processing. The reception process is a process of receiving input information from the key 209, the pedal 208, and the like. The reception process is also a process of receiving detection information detected by various sensors. The control process is a process for controlling a motor or the like. The ROM 202 stores programs executed by the CPU 201 and various initial setting parameters. The RAM 203 temporarily stores a timer, a counter, a flag, and the like. The storage device 29 stores various setting information input by the worker. The CPU 201 is electrically connected to the ROM 202, the RAM 203, and the storage device 29, respectively. The CPU 201 can access the storage area of the ROM 202, the RAM 203, and the storage device 29.

  The pedal 208 is electrically connected to the CPU 201. The operator uses the pedal 208 to adjust the cloth transfer speed. The CPU 201 can recognize the depression amount of the pedal 208. The CPU 201 determines the rotation speeds of the upper transfer roller 22 and the lower transfer roller 25 and the rotation speeds of the drive gear 122 and the driven gear 123 based on the recognized depression amount of the pedal 208.

  The key 209 is electrically connected to the CPU 201. The operator uses the key 209 when performing various operation setting information. The CPU 201 recognizes the pressing state of the key 209 by the operator. The CPU 201 stores various operation setting information in the storage device 29 based on the recognized depression state of the key 209.

  The display drive driver 205 is electrically connected to the CPU 201. The display drive driver 205 is electrically connected to the liquid crystal display unit 207. The CPU 201 displays a desired image on the liquid crystal display unit 207 via the display driving driver 205.

  The motor drive driver 206 is electrically connected to the CPU 201. The motors 91 to 93 are electrically connected to the motor drive driver 206, respectively. The CPU 201 controls the motors 91 to 93 via the motor drive driver 206.

  The air drive driver 204 is electrically connected to the CPU 201. The air drive driver 204 is electrically connected to the first air cylinders 24, 71, 65. The CPU 201 controls the pressure of air sent to the air inlets of the first air cylinders 24, 71, 65 via the air drive driver 204. The support portion 16 moves to the use position and the maintenance position based on the operation of the first air cylinder 24. Based on the operation of the air cylinder 71, the lock mechanism unit 70 switches between a state where the lid 47 can be opened and a state where the lid 47 cannot be opened. The pressing part 64 opens and closes the valve 40 based on the operation of the air cylinder 65.

  The pressure sensor 68 is electrically connected to the CPU 201. The CPU 201 can acquire the gas pressure detected by the pressure sensor 68. The compressor 69 is electrically connected to the CPU 201. The CPU 201 can control the operation of the compressor 69.

  The main process of the cloth bonding apparatus 1 will be described with reference to FIG. When the operator performs an operation for starting the cloth bonding operation via the key 209, the CPU 201 executes a main process.

  The CPU 201 moves the pressing portion 64 downward in the initial state where the main process is not executed. The CPU 201 moves the movable unit 72 to the right. The lid 47 is in an openable state.

  The operator stores the cartridge 60 in the storage chamber 18 before performing the operation of starting the bonding operation through the key 209. If the operator does not have a hole in the upper wall of the cartridge 60, the operator makes a hole in the upper wall of the cartridge 60. The operator closes the lid 47 after housing the cartridge 60 in the storage chamber 18. The compressor 69 sends air into the storage chamber 18.

  In the above state, the main process starts. The CPU 201 determines whether or not the operator has started the bonding operation by depressing the pedal 208 (S11). CPU201 returns to S11, when an operator is not performing operation mentioned above (S11: NO). The CPU 201 continuously monitors the depression of the pedal 208 by the worker.

  When the CPU 201 detects the depression of the pedal 208 (S11: YES), the CPU 201 acquires the gas pressure in the storage chamber 18 detected by the pressure sensor 68. When the acquired gas pressure is equal to or higher than the predetermined value (S13: YES), the CPU 201 moves the piston of the second air cylinder 71 and moves the movable portion 72 to the left. The movable part 72 fits in the keyhole 73. The lid 47 is in an unopenable state (S15). The CPU 201 moves the piston of the third air cylinder 65 and moves the pressing portion 64 upward (S17). The sphere 43 in the valve 40 moves upward. A gap is formed between the hole 44 and the sphere 43. The air sent out by the compressor 69 into the storage chamber 18 pushes the inner lid 56 in the cartridge 60 downward, and the inner lid 56 pushes the adhesive downward. The adhesive flows out from the inside of the cartridge 60 through the gap between the hole 44 and the sphere 43. The adhesive flows through the hole 63 and the supply path 81 and flows to the gear pump 124.

  The gear pump 124 is driven. The gear pump 124 sends the adhesive from the supply path 81 to the supply paths 82 to 84. The adhesive is discharged from the nozzle 17. The second motor 92 and the third motor 93 rotate, and the upper transfer roller 22 and the lower transfer roller 25 rotate. When the operator releases the depression of the pedal 208, the gear pump 124 stops and the second motor 92 and the third motor 93 also stop. The operator operates the pedal 208 to bond the upper cloth 151 and the lower cloth 152 over an arbitrary length. The CPU 201 ends the process.

  When the acquired pressure is less than the predetermined value (S13: NO), the CPU 201 moves the piston of the second air cylinder 71 and moves the movable portion 72 to the right. The movable part 72 comes out of the keyhole 73. The lid 47 is in an openable state (S19). The CPU 201 moves the piston of the third air cylinder 65 and moves the pressing portion 64 downward. The sphere 43 in the bulb 40 moves downward and closes the hole 44. The adhesive stops flowing out (S21). In order to notify the operator that the bonding operation cannot be performed, the CPU 201 displays on the liquid crystal display unit 207 that an abnormality has occurred (S23). The CPU 201 ends the process.

  As described above, in the present embodiment, when the cloth bonding apparatus 1 detects that the lid portion 47 is not open, the third air cylinder 65 drives the pressing portion 64 to open the valve 40. Then, an adhesive is supplied from the inside of the cartridge 60 to the outside. The cloth bonding apparatus 1 can apply a predetermined pressure into the cartridge 60 with the storage chamber 18 sealed. Therefore, the cloth bonding apparatus 1 can send an appropriate amount of adhesive to the gear pump 124 and discharge it from the nozzle 17.

  When the cloth bonding apparatus 1 detects that the lid portion 47 is open, the third air cylinder 65 drives the pressing portion 64 to close the valve 40 and prohibits the adhesive from flowing out of the cartridge 60. . Therefore, the cloth bonding apparatus 1 can prevent the adhesive from flowing out of the cartridge 60 in the state where the lid portion 47 is opened. The cloth bonding apparatus 1 moves the pressing portion 64 downward when the operator opens the lid portion 47. The pressing part 64 does not push up the sphere 43. Therefore, the cloth bonding apparatus 1 can prevent the adhesive from leaking into the storage chamber 18 when the operator steps on the pedal 208 with the lid 47 opened.

  The present invention is not limited to the above embodiment, and various modifications can be made. In the above-described embodiment, the cloth bonding apparatus 1 switches between the state in which the lid portion 47 can be opened and the state in which the lid portion 47 cannot be opened by the second air cylinder 71 moving the movable portion 72. The present invention is not limited to this method. For example, a protrusion may be attached to the lid 47 and a hole may be attached to the air cylinder. In the above-described case, the air cylinder may be switched between a state where the lid 47 can be opened and a state where the lid 47 cannot be opened by moving the hole.
