  The first portion 41A extends upward from the upper portion of the base portion 410 and the portion downstream of the center in the transport direction. When the rotating body 41 is in the first state (see FIG. 15), the first portion 41A is inserted from the lower side into the slit 122 (see FIGS. 2 and 3) provided on the receiving surface 12A of the cradle 12, and the upper side Protrusively. At this time, the first portion 41A protrudes above the horizontal portion 97A of the transport region 97. On the other hand, when the rotating body 41 is in the second state (see FIG. 16), the first portion 41A is disposed below the receiving surface 12A of the cradle 12 and protrudes above the horizontal portion 97A of the transport region 97. do not do. The upper end of the first portion 41A is in contact with the horizontal portion 97A from below.

  The second portion 41 </ b> B extends downstream from the downstream end of the base portion 410. The second portion 41B is disposed below the receiving surface 12A of the cradle 12 and does not protrude upward from the receiving surface 12A in the process in which the rotating body 41 rotates between the first state and the second state. When the rotating body 41 is in the first state, the upper end of the second portion 41B contacts the portion of the inner surface of the cradle 12 downstream of the slit 122 from the inside. When the rotating body 41 rotates in the clockwise direction by the biasing force of the spring 43, the rotation of the rotating body 41 is restricted by the second portion 41B coming into contact with the inner surface of the cradle 12. On the other hand, when the rotating body 41 is in the second state, the upper end of the second portion 41B is spaced downward from the inner surface of the cradle 12.

  The third portion 41 </ b> C extends upstream from the upstream end of the base portion 410. The third portion 41C is disposed below the receiving surface 12A of the cradle 12 and does not protrude upward from the receiving surface 12A in the process in which the rotating body 41 rotates between the first state and the second state. When the rotating body 41 is in the first state, the upper end of the third portion 41C is separated downward from the inner surface of the cradle 12. When the rotating body 41 is in the second state, the upper end of the third portion 41C comes into contact with the portion of the inner surface of the cradle 12 upstream of the slit 122 from the inside. When the rotating body 41 rotates counterclockwise against the urging force of the spring 43, the rotation of the rotating body 41 is restricted by the third portion 41C coming into contact with the inner surface of the cradle 12.

  The detection unit 42 is provided on the downstream side with respect to the rotating body 41. The detection unit 42 includes a fixed unit 42A and an optical element 42B. The fixing portion 42A is a jig for fixing the optical element 42B to the inner surface of the cradle 12. The optical element 42B has a light emitting part and a light receiving part. The light emitting unit and the light receiving unit are spaced apart in the left-right direction. The light emitting unit emits light toward the light receiving unit. The light receiving unit can detect light emitted from the light emitting unit. The detection unit 42 outputs different signals depending on whether or not the light emitted from the light emitting unit in the optical element 42B is detected by the light receiving unit.

  As shown in FIG. 15, when the rotating body 41 is in the first state, the second portion 41B is disposed between the light emitting portion and the light receiving portion of the optical element 42B. In this case, the light emitted from the light emitting portion of the optical element 42B is blocked by the second portion 41B. For this reason, when the rotating body 41 is in the first state, the light receiving portion of the optical element 42B cannot detect the light emitted from the light emitting portion. On the other hand, as shown in FIG. 16, when the rotating body 41 is in the second state, the second portion 41B is disposed below the space between the light emitting portion and the light receiving portion of the optical element 42B. In this case, the light emitted from the light emitting unit of the optical element 42B can be detected by the light receiving unit.

Hereinafter, the predetermined conveyance position in the sensor 4 is referred to as a “first conveyance predetermined position”. The first portion 41A of the sensor 4 is directly provided at the first conveyance predetermined position of the horizontal portion 97A. When the first to fourth predetermined positions pass through the first conveyance predetermined position in the state where the first to fourth through portions are formed at the first to fourth predetermined positions of the mount 2, the biasing force of the spring 43 causes the first One portion 41A protrudes upward from the horizontal portion 97A. For this reason, the rotating body 41 of the sensor 4 is in the first state. On the other hand, when the first to fourth predetermined positions pass through the first conveyance predetermined position in the state where the first to fourth through portions are not formed at the first to fourth predetermined positions of the mount 2, the biasing force of the spring 43 is applied. On the other hand, the first portion 41A is pushed downward. For this reason, the rotating body 41 of the sensor 4 is in the second state.

<Packaging processing>
The packaging process (see FIG. 19) executed by the CPU 201 of the packaging device 1 will be described with reference to FIGS. It is assumed that the film roll 22 (see FIG. 5) is attached to the attachment members 141 and 142 (see FIG. 4) before the packaging device 1 is turned on. When the packaging apparatus 1 is powered on, the CPU 201 starts the packaging process by reading and executing the program stored in the flash memory 202. 21 to 29 are sectional views taken along the line AA in FIG.

  As shown in FIG. 19, the CPU 201 initializes the state of the packaging device 1 (S1). Specifically, it is as follows. The CPU 201 drives the motor 221 by controlling the drive unit 211 and raises the push-down mechanism 39 to be arranged at the top. The pressing rollers 30 to 33 supported by the pair of support members 34 are arranged at the uppermost position (see FIG. 21). The CPU 201 drives the motor 222 by controlling the drive unit 212 to rotate the belts 511 and 512 (see FIG. 21) of the transport mechanism 50. When the sensor 205 (see FIG. 17) detects the reflecting plate, the CPU 201 controls the driving unit 212 to stop driving the motor 222. As a result, the conveying unit 60 protrudes upward from the receiving surface 12A (see FIG. 3) of the receiving tray 12 (see FIG. 21). The packaging device 1 is in a state in which the user can set the mount 2 on the receiving surface 12A of the receiving tray 12. The CPU 201 controls the driving unit 213 to drive the motor 223, and lowers the five heating units 861 and arranges them at the lowest position. The heater 861A of each heating unit 861 is separated downward from the conveyance path 103 (see FIG. 21). The CPU 201 controls the driving unit 214 to drive the motor 224 and rotate the film moving mechanism 25 clockwise. As a result, the film moving mechanism 25 is disposed at the pre-retraction position (see FIG. 21). The CPU 201 controls the driving unit 215 to drive the motor 225 and move the cutting unit 77 to the left side. The CPU 201 controls the drive unit 216 to drive the motor 226 to move the pair of support members 78 to the separation position. The holding member 72 is in a state of being separated downward with respect to the holding portion 71 </ b> B of the mount guide member 71. The CPU 201 stops energization of the electromagnetic brake 82. As a result, the grip roller 81 can be freely rotated. CPU201 stops energization to heater 861A.

  The user perforates 94A, 94B at positions corresponding to a desired transport speed when the mount 2 is transported toward the downstream side among the first predetermined position and the second predetermined position of the bottom surface portion 905 of the mount 2. To form a penetrating portion. The user perforates 94C and 94D at positions corresponding to a desired conveyance speed when the mount 2 is conveyed toward the upstream side among the third predetermined position and the fourth predetermined position of the bottom surface portion 905 of the mount 2. To form a penetrating portion. The user causes perforations 95 </ b> A and 95 </ b> B to form through portions at positions corresponding to the desired amount of winding among the fifth desired position and the sixth desired position of the side surface portion 907 of the mount 2. A user forms a penetration part by perforation 95C and 95D in the position corresponding to the desired heating time among the 7th desired position and the 8th desired position of side part 907 of mount 2.

  The user pulls the film 24 downward from the film roll 22. The user sandwiches the film 24 from both sides in the transport direction with the feeding rollers 654A and 654B. The user passes the film 24 on the upstream side of the pressing roller 33. The user places the leading end of the film 24 below the transport path 103 (see FIG. 21) and downstream of the holding portion 71B of the mount guide member 71 (see FIG. 21). The user places the mount 2 on the receiving tray 12 (see FIG. 21). The mount 2 is positioned by the transport unit 60. The side 901 of the bottom surface portion 905 of the mount 2 is disposed on the downstream side, and the side 902 is disposed on the upstream side. The article 3 is placed on the bottom surface portion 905 of the mount 2 (see FIG. 21).

  The user performs an input operation for notifying the packaging apparatus 1 that preparation has been completed via the operation unit 206. The CPU 201 controls the driving unit 216 to drive the motor 226 to move the pair of support members 78 to the close positions. The holding member 72 is close to the downstream side of the holding portion 71B of the mount guide member 71 (see FIG. 21). The leading end of the film 24 drawn out from the film roll 22 is sandwiched between the holding direction 71B and the holding member 72 of the mount guide member 71 from both sides in the transport direction. The film 24 and the transport path 103 intersect at the front end portion of the film 24. The film 24 extends in the vertical direction.

  The CPU 201 determines whether an instruction to start packaging has been input (S11). CPU201 returns a process to S11, when the instruction | indication of a packaging start is not input (S11: NO). When the user inputs a packaging start instruction via the operation unit 206, the CPU 201 determines that a packaging start instruction is input (S11: YES). The CPU 201 drives the solenoid 16C to move the connecting gear 652 (see FIG. 5) to the extended position (S13). The CPU 201 controls the drive unit 217 to rotate the motor 227. The feeding roller 654B rotates according to the rotation of the motor 227. The film 24 is forcibly fed from the film roll 22 by feeding rollers 654A and 654B (see FIG. 5) (S15, arrow 171 and FIG. 21). The CPU 201 continuously feeds the film 24 by the feeding rollers 654A and 654B until the connecting gear 652 is moved to the winding position by the process of S37 described later. For this reason, the film 24 is loosened.

  CPU201 performs a determination process (refer FIG. 20) in order to determine a packaging parameter (S16). The determination process will be described with reference to FIG. Four predetermined times (first time, second time, third time, and fourth time) used in the determination process will be described. In the first to fourth times, each of the first to fourth predetermined positions of the mount 2 is moved to the first transport predetermined position (a position where the sensor 4 can be detected) after the transport of the mount 2 is started. It corresponds to the time required to do. Also, during the first to fourth times, after the transport of the mount 2 is started, each of the fifth to eighth predetermined positions of the mount 2 is a second transport predetermined position (a position that can be detected by the sensor 204B). Corresponds to the time required to travel to. The four predetermined times become longer in the order of the first time, the second time, the third time, and the fourth time.

  The CPU 201 controls the drive unit 212. The CPU 201 rotates the motor 222 in the forward direction. The belts 511 and 512 rotate in the forward direction (the direction of the arrow 181 in FIG. 21). The transport unit 60 transports the mount 2 from the upstream side to the downstream side along the transport path 103 (S81). The CPU 201 controls the rotation speed of the motor 222 so that the mount 2 is conveyed at a predetermined initial speed.

  The CPU 201 determines whether or not the elapsed time since the transport of the mount 2 has reached the first time (S83). When it is determined that the elapsed time has not reached the first time (S83: NO), the CPU 201 returns the process to S83. The CPU 201 continuously monitors the elapsed time. If it is determined that the elapsed time has reached the first time (S83: YES), the CPU 201 advances the process to S85.

  The CPU 201 determines whether through portions are formed at the first predetermined position and the fifth predetermined position of the mount 2 based on signals output from the sensors 4 and 204B. When it is determined that the first through portion is formed at the first predetermined position, the CPU 201 sets “1” to the first bit of the first variable. When it is determined that the first through portion is not formed in the first predetermined area, the CPU 201 sets “0” to the first bit of the first variable. When it is determined that the fifth through portion is formed at the fifth predetermined position, the CPU 201 sets “1” to the first bit of the second variable. When it is determined that the fifth through portion is not formed in the fifth predetermined area, the CPU 201 sets “0” to the first bit of the second variable (S85). CPU201 advances processing to S87.

The CPU 201 determines whether through portions are formed at the second predetermined position and the sixth predetermined position of the mount 2 based on signals output from the sensors 4 and 204B. The CPU 201 determines that the second bit of the first variable is “1” (when the through portion is formed) “0” (the through portion) depending on whether or not the second through portion is formed at the second predetermined position. Is set). The CPU 201 sets either “1” or “0” to the second bit of the second variable depending on whether or not the sixth penetration portion is formed at the sixth predetermined position (S89). CPU201 advances processing to S91.

  The CPU 201 determines whether or not the elapsed time since the transport of the mount 2 has reached the third time (S91). When it is determined that the elapsed time has not reached the third time (S91: NO), the CPU 201 returns the process to S91. The CPU 201 continuously monitors the elapsed time. When it is determined that the elapsed time has reached the third time (S91: YES), the CPU 201 advances the process to S93. The CPU 201 determines whether through portions are formed at the third predetermined position and the seventh predetermined position of the mount 2 based on signals output from the sensors 4 and 204B. The CPU 201 sets either “1” or “0” to the third bit of the first variable depending on whether or not the third through portion is formed at the third predetermined position. The CPU 201 sets any one of “1” and “0” to the third bit of the second variable according to whether or not the seventh through portion is formed at the seventh predetermined position (S93). CPU201 advances processing to S95.

  The CPU 201 determines whether or not the elapsed time since the transport of the mount 2 has reached the fourth time (S95). When it is determined that the elapsed time has not reached the fourth time (S95: NO), the CPU 201 returns the process to S95. The CPU 201 continuously monitors the elapsed time. When it is determined that the elapsed time has reached the fourth time (S95: YES), the CPU 201 advances the process to S97. The CPU 201 determines whether through portions are formed at the fourth predetermined position and the eighth predetermined position of the mount 2 based on signals output from the sensors 4 and 204B. The CPU 201 sets either “1” or “0” to the fourth bit of the first variable depending on whether or not the fourth through portion is formed at the fourth predetermined position. The CPU 201 sets either “1” or “0” to the fourth bit of the second variable depending on whether or not the eighth penetration portion is formed at the eighth predetermined position (S97). CPU201 advances processing to S101.

  In the table 202A, the CPU 201 sets the first packaging parameter corresponding to the combination of the bit pattern of the first bit and the second bit of the first variable (conveying speed when the backing sheet 2 is conveyed downstream, hereinafter “first 1 conveyance speed "). The CPU 201 sets the first packaging parameter corresponding to the combination of the bit pattern of the third bit and the fourth bit of the first variable in the table 202A (the conveyance speed when the mount 2 is conveyed upstream, hereinafter “the first number”). 2) "is determined. CPU201 determines the 2nd packaging parameter (rolling amount) corresponding to the combination of the bit pattern of the 1st bit and the 2nd bit of the 2nd variable among tables 202B. CPU201 determines the 2nd packaging parameter (heating time) corresponding to the combination of the bit pattern of the 3rd bit and the 4th bit of the 2nd variable among tables 202B (S101). The CPU 201 stores the determined first transport speed, second transport speed, winding amount, and heating time in the RAM 203 (S103). The CPU 201 ends the determination process and returns the process to the packaging process (see FIG. 19).

  By starting the conveyance of the mount 2 by the process of S81 (see FIG. 20) of the determination process, the downstream end (side 901) of the bottom surface portion 905 of the mount 2 comes into contact with the film 24, and then the holding member 72 (arrow 182 in FIG. 22). The side 901 of the bottom surface portion 905 of the mount 2 pushes the film 24 downstream. The side 901 of the bottom surface portion 905 of the mount 2 approaches the movement path 104 from the upstream side and passes above the five heating units 861 (see FIG. 22). The leading end of the film 24 is sandwiched between the holding portion 71 </ b> B and the holding member 72 of the mount guide member 71. When the film 24 is pushed downstream by the side 901 of the bottom surface portion 905 of the mount 2, the front end of the film 24 goes around the lower surface of the bottom surface portion 905 of the mount 2.

  When the mount 2 is transported to the downstream side, the side 901 of the bottom surface portion 905 of the mount 2 crosses the intersection position 105 where the transport path 103 and the movement path 104 intersect from the upstream side toward the downstream side. The mount 2 moves further downstream. As shown in FIG. 23, the film 24 extending from the film roll 22 is bent by the pressing roller 33 and extends downstream, and reaches the side 901 of the bottom surface portion 905 of the mount 2 and the downstream side of the article 3. The film 24 is disposed at a position covering the bottom surface portion 905 of the mount 2 and the upper side of the article 3. The pressing rollers 30 to 32 are in a state of being disposed above the film 24 extending above the mount 2 and the article 3.

  As shown in FIG. 19, the CPU 201 starts transporting the backing sheet 2 to the downstream side by the processing of S <b> 81 (see FIG. 20), and then transports the backing sheet 2 according to the pulse signal output from the encoder 232. The number of rotations of the motor 222 after the start is specified. The CPU 201 determines whether or not the side 901 of the bottom surface portion 905 of the mount 2 has moved to the downstream side by a predetermined distance with respect to the upper position of the five heating units 861 in the state of being arranged at the uppermost position. Judgment is made based on the number of revolutions 222. When the CPU 201 determines that the side 901 of the bottom surface portion 905 of the mount 2 has moved a predetermined distance downstream from the upper position of the five heating units 861, the CPU 201 controls the driving unit 212 to stop driving the motor 222. Then, the conveyance of the backing sheet 2 to the downstream side is stopped (S19).

  CPU201 controls actuator 213, drives motor 223, and raises five heating units 861 (S21). After the five heating units 861 are arranged at the uppermost position, the CPU 201 controls the drive unit 213 to stop driving the motor 223 and stop the five heating units 861 from rising. As shown in FIG. 23, when the five heating units 861 are raised to the top (arrow 183), the upper sides of the five heating units 861 are close to the transport path 103 from below and are slightly more than the transport path 103. Is placed on the upper side. The side 901 of the bottom surface portion 905 of the mount 2 has moved a predetermined distance downstream from the upper position of the five heating units 861, and the film 24 has wrapped around the lower surface of the bottom surface portion 905 of the mount 2. . Accordingly, the film 24 is sandwiched between the upper surface of the five heating units 861 and the lower surface of the bottom surface portion 905 of the mount 2 in a state where the five heating units 861 are arranged at the uppermost position.

  As shown in FIG. 19, the CPU 201 heats the heater 861A (S23). The heater 861A heats and melts the leading end portion of the film 24. The front end portion of the melted film 24 is welded to the mount 2 (S23). The CPU 201 stops heating the heater 861A after the heating time stored in the RAM 203 has elapsed by the process of S103 (see FIG. 20) after starting the heating of the heater 861A.

  The CPU 201 controls the drive unit 213 to drive the motor 223 to lower the five heating units 861 (S25, arrow 184 (see FIG. 24)). The upper side of each heating unit 861 is separated from the conveyance path 103. After the five heating units 861 are arranged at the lowest position, the CPU 201 controls the driving unit 213 to stop driving the motor 223 and stop the lowering of the five heating units 861.

  CPU201 controls actuator 216, drives motor 226, and moves a pair of support members 78 to a separation position (S27). As shown in FIG. 24, the pair of support members 78 rotate in the direction of the arrow 185, whereby the holding member 72 is separated downward from the holding portion 71 </ b> B of the mount guide member 71. The holding portion 71B and the holding member 72 of the mount guide member 71 release the front end portion of the film 24 in a sandwiched state.

  As shown in FIG. 19, the CPU 201 drives the motor 222 by controlling the drive unit 212. The CPU 201 rotates the motor 222 in the forward direction so that the belts 511 and 512 rotate in the forward direction. The mount 2 is conveyed downstream (S29, arrow 186 (see FIG. 24)). The CPU 201 controls the rotational speed of the motor 222 so that the mount 2 is transported downstream at the first transport speed stored in the RAM 203 by the process of S103 (see FIG. 20). In addition, the front-end | tip part of the film 24 is the state adhere | attached on the base_sheet | mounting_paper 2 by the process of S23. For this reason, the leading end portion of the film 24 moves downstream as the mount 2 moves downstream. In addition, the guide rail 74 for moving the cutting part 77 is arrange | positioned under the conveyance path | route 103, and contacts the front-end | tip part of the film 24 from below. For this reason, the leading end portion of the film 24 is in a state of extending downstream along the conveyance path 103 when moving along with the movement of the mount 2.

  As shown in FIG. 24, the transport unit 60 moves onto the cradle 13, and the downstream side of the mount 2 is transported to the cradle 13. An upstream end (side 902) of the bottom surface portion 905 of the mount 2 passes over the mount guide member 71. The side 902 of the bottom surface portion 905 of the mount 2 crosses the intersection position 105 from the upstream side to the downstream side.

  The CPU 201 specifies the number of rotations of the motor 222 after starting the transport of the mount 2 according to the pulse signal output from the encoder 232 after starting the transport of the mount 2 to the downstream side in the process of S29. To do. The CPU 201 determines whether or not the side 902 of the bottom surface portion 905 of the mount 2 has moved downstream by a predetermined distance with respect to the intersection position 105 based on the identified number of rotations of the motor 222. When the CPU 201 determines that the side 902 of the bottom surface portion 905 of the mount 2 has moved to the downstream side by a predetermined distance with respect to the intersection position 105, the CPU 201 controls the drive unit 212 to stop driving the motor 222. The downstream conveyance is stopped (S31).

  The CPU 201 controls the driving unit 214 to drive the motor 224 to move the film moving mechanism 25 from the pre-retraction position to the post-retraction position (S33). The moving member 27 of the film moving mechanism 25 temporarily moves above the transport path 103 from below the holding portion 71B of the mount guide member 71. Thereafter, the moving member 27 moves again below the transport path 103, and is disposed downstream of the grip roller 81 and below the transport path 103 (see arrow 187, FIG. 24). The moving member 27 moves the leading end portion of the film 24 to the lower side of the conveying path 103 and to the downstream side of the moving path 104 in the process of moving from the upper side to the lower side of the conveying path 103.

  The CPU 201 controls the drive unit 211 to drive the motor 221 to move the pressing mechanism 39 to the lowest position (S35). The pressing roller 30 moves from the highest level to the lowest level along the movement path 104. In the process of movement, the pressing rollers 30 and 32 come into contact with the film 24 disposed below from the upper side, and push the film 24 downward (see arrow 188, FIG. 25). The film 24 covers the bottom surface portion 905 of the mount 2 and the downstream side, upper side, and upstream side of the article 3. As shown in FIG. 25, the gear of the grip roller 81 is fitted to the gear of the pressing roller 30 with the pressing mechanism 39 disposed at the lowest position. The film 24 is sandwiched between the grip roller 81 and the pressing roller 30. The pressing roller 31 contacts the conveyance path 103 from below.

  As shown in FIG. 19, the CPU 201 drives the solenoid 16C to move the connecting gear 652 (see FIG. 5) to the winding position. In the initialization process of S1, energization to the electromagnetic brake 82 is stopped. For this reason, the grip roller 81 and the pressing roller 30 are in a rotatable state. For this reason, according to rotation of the motor 227, the film 24 is wound up on the film roll 22 (S37, arrow 172, refer FIG. 25). Tension acts on the film 24. The film 24 comes into close contact with the mount 2 and the article 3 due to the tension acting on the film 24.

  The CPU 201 starts winding the film 24 by the process of S37 and then when the film 24 for the winding amount stored in the RAM 203 is wound on the film roll 22 by the process of S103 (see FIG. 20), The drive unit 217 is controlled to stop the rotation of the motor 227. Thereby, the winding of the film 24 onto the film roll 22 is stopped (S39). The CPU 201 drives the solenoid 16C to move the connecting gear 652 (see FIG. 5) to the extended position (S41). As a result, the motor 227 is connected to the feeding roller 654B via the motor gear 670, the connection gear 652, the first pulley, the transmission belt 653, and the second pulley. In other words, the rotational driving force of the motor 227 can be transmitted to the connecting gear 651. On the other hand, the motor 227 and the connection gear 651 are not connected. That is, the rotational driving force of the motor 227 is not transmitted to the feeding roller 654B.

  The CPU 201 energizes the electromagnetic brake 82 with the current having the first current value. In this case, rotational torque (hereinafter referred to as “first rotational torque”) corresponding to the first current value acts on the grip roller 81 connected to the electromagnetic brake 82 (S43).

  The CPU 201 rotates the motor 222 in the reverse direction so that the belts 511 and 512 rotate in the reverse direction (S45). The mount 2 moves from the downstream side to the upstream side (see arrow 189, FIG. 26). The CPU 201 controls the rotational speed of the motor 222 so that the mount 2 is transported upstream at the second transport speed stored in the RAM 203 by the process of S103 (see FIG. 20). The side 902 of the bottom surface portion 905 of the mount 2 comes into contact with the film 24 and is pushed upstream. On the left and right sides of the side 902 of the bottom surface portion 905 of the mount 2, gaps 3414 and 3424 between the first extending portion 34B (342B) and the second extending portion 34C (342C) of the pressing mechanism 39 (FIG. 6). Etc.) from the downstream side. The second extending portion 34C (342C) presses the bottom surface portion 905 of the mount 2 from above, and suppresses the mount 2 from being lifted upward.

  The side 902 of the bottom surface portion 905 of the mount 2 approaches the intersection position 105 from the downstream side. The side 902 of the bottom surface portion 905 of the mount 2 crosses the intersection position 105 from the downstream side toward the upstream side. The pressing roller 31 of the pressing mechanism 39 is in contact with the lower surface of the mount 2, and gaps 3414 and 3424 between the first extending portion 34B (342B) and the second extending portion 34C (342C) (see FIG. 6 and the like). Then, the mount 2 is guided upstream. The side 902 of the bottom surface portion 905 of the mount 2 passes through the upper position of the five heating units 861 and moves upstream. Further, the mount 2 moves upstream. The mount 2 passes above the five heating units 861 and moves upstream.

  In the process in which the mount 2 moves to the upstream side, the film 24 goes around to the lower side of the upstream portion of the bottom surface portion 905 of the mount 2. The film 24 that wraps around the underside of the mount 2 is insufficient. For this reason, in order to make up for the shortage of the film 24, the film 24 will move in the moving direction (the direction of the arrow 173 (see FIG. 27) when it is unwound from the film roll 22; hereinafter referred to as the “feeding direction”). And However, the film 24 is sandwiched between the grip roller 81 and the pressing roller 30. Further, the first rotational torque is applied to the grip roller 81 by the process of S43. For this reason, the movement of the film 24 in the feeding direction is suppressed by the grip roller 81 and the pressing roller 30. The first load acts on the film 24 from the grip roller 81 in the direction opposite to the feeding direction (arrow 174 (see FIGS. 26 and 27), hereinafter referred to as “opposite direction”). Thereby, tension is applied to the film 24, and the film 24 adheres to the article 3 (see FIG. 26).

  In accordance with the pulse signal output from the encoder 232, the CPU 201 specifies the number of rotations of the motor 222 after the transport of the mount 2 to the upstream side is started by the process of S45. The CPU 201 determines whether the mount 2 has moved upstream by a predetermined distance with respect to the upper positions of the five heating units 861 based on the specified number of rotations. When the CPU 201 determines that the mount 2 has moved a predetermined distance upstream from the upper position of the five heating units 861, the CPU 201 controls the drive unit 212 to stop driving the motor 222 and stop the transport of the mount 2. (S47).

  The CPU 201 energizes the electromagnetic brake 82 with the current having the second current value. In this case, a rotational torque corresponding to the second current value (hereinafter referred to as “second rotational torque”) acts on the grip roller 81 connected to the electromagnetic brake 82 (S49). The second rotational torque is larger than the first rotational torque that is the rotational torque when the current having the first current value is energized to the electromagnetic brake 82. A second load acts on the film 24 from the grip roller 81 in the opposite direction. That is, the load in the opposite direction acting on the film 24 is changed from the first load to the second load. Since the second load is larger than the first load, the movement of the film 24 in the feeding direction is suppressed more strongly than the state where the first load is acting on the film 24. The film 24 cannot move with respect to the grip roller 81 and the pressing roller 30.

  The CPU 201 controls the driving unit 215 to drive the motor 225, and moves the cutting unit 77 from the left side to the right side along the guide rail 74 (see FIG. 10). When the cutting portion 77 moves to the right side, the film 24 is closer to the film roll 22 than the portion sandwiched between the gear of the grip roller 81 and the gear of the pressing roller 30 and between the pressing rollers 30 and 32. Is cut by the blade portion 771 (S51). The cutting part 77 cuts off a part of the film 24 that covers the bottom surface part 905 of the mount 2 and the article 3 from the film roll 22 side.

  After the film 24 is cut, the portion of the film 24 cut off from the film roll 22 side tends to come off from the portion sandwiched between the grip roller 81 and the pressing roller 30 due to the tension acting on the film 24. However, the gear of the grip roller 81 and the gear of the pressing roller 30 are fitted to sandwich the film 24 therebetween. The electromagnetic brake 82 applies a second rotational torque, which is greater than the first rotational torque, to the grip roller 81. For this reason, the film 24 does not come off from the portion sandwiched between the grip roller 81 and the pressing roller 30.

  On the other hand, the cut end of the film 24 extending from the film roll 22 hangs downstream of the mount guide member 71. The CPU 201 controls the drive unit 216 to drive the motor 226 to move the pair of support members 78 to the close positions (S53). As shown in FIG. 28, the pair of support members 78 swing in the direction of the arrow 190. The holding member 72 comes close to the holding portion 71B of the mount guide member 71. An end portion of the film 24 cut by the cutting portion 77 is sandwiched between the holding portion 71 </ b> B and the holding member 72 of the mount guide member 71.

  As shown in FIG. 19, the CPU 201 controls the drive unit 213 to drive the motor 223 and raise the five heating units 861 (S55). After the five heating units 861 are arranged at the uppermost position, the CPU 201 controls the drive unit 213 to stop driving the motor 223 and stop the five heating units 861 from rising. As shown in FIG. 28, the top surfaces of the five heating units 861 approach the transport path 103 from below in a state where the five heating units 861 are raised to the top (arrow 191). By arranging the five heating units 861 at the uppermost position, a portion of the film 24 that is close to the welded portion by the process of S13 (hereinafter referred to as a “first portion”) and a cut portion of the process of S37 are close to each other. A portion to be performed (hereinafter referred to as “second portion”) is sandwiched between the mount 2 and the five heating units 861.

  As shown in FIG. 19, the CPU 201 heats the heater 861A (S57). The heater 861A heats and melts the second portion of the film 24. The second part of the melted film 24 is welded to the first part of the film 24. The CPU 201 stops heating the heater 861A after the heating time stored in the RAM 203 has elapsed by the process of S103 (see FIG. 20) after starting the heating of the heater 861A. The CPU 201 controls the drive unit 213 to drive the motor 223 to lower the five heating units 861 (S59, arrow 192 (see FIG. 29)). The upper surface of each heating unit 861 is separated from the conveyance path 103. The CPU 201 controls the driving unit 213 to stop the rotation of the motor 223.

  The CPU 201 stops energization of the electromagnetic brake 82. As a result, the grip roller 81 becomes rotatable (S61). The CPU 201 controls the driving unit 212 to drive the motor 222. The CPU 201 rotates the motor 222 in the forward direction so that the belts 511 and 512 rotate in the forward direction. The mount 2 is conveyed downstream (S63, arrow 193 (see FIG. 29)). The mount 2 and the article 3 that have been packaged are conveyed downstream. The CPU 201 controls the drive unit 211 to drive the motor 221 to move the pressing mechanism 39 from the lowest level to the highest level (S65). The pressing roller 30 moves from the lowest position to the highest position along the movement path 104. The CPU 201 controls the driving unit 214 to drive the motor 224 and rotate the film moving mechanism 25 clockwise. As a result, the film moving mechanism 25 is disposed at the pre-retraction position (S67). The CPU 201 ends the packaging process.

<Main functions and effects of this embodiment>
As described above, the CPU 201 of the packaging device 1 detects the presence or absence of the first to fourth through portions at each of the first to fourth predetermined positions of the mount 2 in the process of transporting the mount 2 by the sensor 4. (S85, S89, S93, S97). CPU201 detects the presence or absence of the 5th-8th penetration part in each of the 5th-8th predetermined position of the mount 2 with sensor 204B (S85, S89, S93, S97). CPU201 determines a packaging parameter according to the presence or absence of the detected penetration part (S101). The CPU 201 controls the transport speed of the mount 2 based on the determined first packaging parameter (first transport speed and second transport speed) (S29, S45). The CPU 201 controls the winding amount of the film 24 and the heating time by the heater 861A based on the determined second packaging parameter (winding amount and heating time) (S23, S37, S39, S57). . In this case, the user causes the packaging device 1 to perform a packaging operation based on the desired packaging parameters by forming through portions according to the desired packaging parameters at the first to eighth predetermined positions of the mount 2. Can do. Therefore, the user can easily execute the setting of the packaging parameter as compared with the case where the packaging parameter is set by operating the operation unit 206.

  A horizontal portion 97A of the transport region 97 corresponds to a region through which the bottom surface portion 905 of the mount 2 passes. The horizontal portion 97A is an area where a part of the mount 2 always passes stably even when the size of the mount 2 is changed or the transport position of the mount 2 is shifted. On the other hand, in the packaging device 1, the position where the presence or absence of the first to fourth penetration portions by the sensor 4 can be detected (first conveyance predetermined position) is the slit of the cradle 12 in the horizontal portion 97 </ b> A of the conveyance region 97. This corresponds to the position above 122. The first portion 41A of the sensor 4 is directly provided at the first conveyance predetermined position of the horizontal portion 97A. For this reason, since the sensor 4 can detect the presence or absence of the penetration part in the mount 2 on stable conditions, it can detect the 1st-4th penetration part with high precision. Further, the sensor 4 detects the first to fourth penetration portions by a shielding object or the like as compared with the case where the presence or absence of the first to fourth penetration portions is detected at a position separated from the horizontal portion 97A by, for example, an optical method. It can be suppressed from becoming impossible.

  The sensor 4 includes a shaft part 40, a rotating body 41, and a detection part 42. The rotating body 41 has a first portion 41A and a second portion 41B. The rotating body 41 is rotatable around the shaft portion 40. When the rotating body 41 is in the first state, the first portion 41A protrudes upward from the horizontal portion 97A. On the other hand, when the rotating body 41 is in the second state, the first portion 41A is disposed below the horizontal portion 97A. The detection unit 42 can detect the second portion 41B of the rotating body 41 in the first state by the optical element 42B. In this case, when the 1st-4th penetration part formed in the 1st-4th predetermined position of the mount 2 passes the 1st conveyance predetermined position, the rotary body 41 will be in a 1st state. On the other hand, when the 1st-4th penetration part is not formed in the 1st-4th predetermined position of the mount 2, the rotary body 41 will be in a 2nd state. For this reason, the sensor 4 can detect the presence or absence of the 1st-4th penetration part in the base_sheet | mounting_paper 2 by specifying the state of the rotary body 41 with the optical element 42B. Therefore, the packaging device 1 can easily detect the presence or absence of the first to fourth penetrating portions in the mount 2 with a simple configuration.

  The sensor 204 is disposed on the upstream side of the side plate member 112 and at a position separated from the intersecting portion 97 </ b> B of the transport region 97. The detection unit of the sensor 204B has fifth to eighth through portions at the fifth to eighth predetermined positions of the mount 2 depending on whether or not the reflected light of the infrared light emitted from the light emitting unit is detected by the light receiving unit. Is detected. As described above, the sensor 204 optically detects the presence or absence of the fifth to eighth penetration portions, and thus does not hinder the conveyance of the mount 2. For this reason, the packaging apparatus 1 can detect whether the fifth to eighth through portions are formed in the fifth to eighth predetermined regions of the mount 2 while realizing smooth conveyance of the mount 2.

  The CPU 201 determines whether or not the elapsed time since the transport of the mount 2 by the transport mechanism 50 has reached the first to fourth time (S83, S87, S91, S95). CPU201 specifies a bit pattern according to the signal output from the sensors 4 and 204 at each timing when elapsed time reaches the 1st-4th time, and determines a packaging parameter (S101). For this reason, the user forms the first to eighth penetration portions by the perforations 94 and 95 at positions corresponding to the desired conveyance parameters among the first to eighth predetermined positions of the mount 2, whereby the packaging device 1. Setting of packaging parameters for can be realized. Therefore, the user can more easily execute the setting of the packaging parameters for the packaging device 1.

  Based on the tables 202A and 202B, the CPU 201 determines the first transport speed, the second transport speed, the winding amount of the film 24, and the heating time of the film 24 as packaging parameters (S101). For this reason, for example, when the size of the article 3 to be packaged is easy to collapse, the user can suppress the article 3 from falling by setting the first conveyance speed and the second conveyance speed to be slow. Further, for example, when the size of the article 3 to be packaged is small, the user can wrap the article 3 in a short time by setting the first conveyance speed and the second conveyance speed fast. Further, for example, when there is a possibility that the article 3 is deformed by the tension of the film 24, the user can reduce the tension acting on the film 24 by reducing the amount of winding of the film 24. Further, for example, when the melting point differs depending on the material of the film 24, the user can adjust the heating time of the film 24 by the heater 861 </ b> A and can appropriately weld the film 24 to the mount 2. Further, the user can set the first transport speed, the second transport speed, the winding amount, and the heating time in the packaging device 1 independently of each other.

  The base sheet 2 can reinforce the strength of the bottom surface portion 905 by the two side surface portions 906 and 907 by bending each of the two bent portions 911 and 912. Therefore, the mount 2 can suppress the bottom surface portion 905 from being bent by the tension of the film 24 when the article 3 is placed on the bottom surface portion 905 and wrapped with the film 24. Further, the mount 2 can be formed with holes 926 and 927 by a plurality of cuts 920 and 930 by bending each of the two bent portions 911 and 912. In this case, the packaging apparatus 1 can appropriately transport the mount 2 by moving the transport unit 60 with the second transport units 61B and 62B of the transport mechanism 50 attached to the holes 926 and 927. The mount 2 has a perforation 94 on the bottom surface portion 905 and a perforation 95 on the side surface portion 906. Each of the perforations 94 and 95 can form a penetrating portion in the mount 2. For this reason, the user can form easily the penetration part corresponding to the packaging parameter desired by perforation 94,95.

  In the mount 2, the perforation 94 can form first to fourth through portions at first to fourth predetermined positions arranged in parallel with the bent portions 911 and 912. Further, the perforation 95 can form fifth to eighth through portions at fifth to eighth predetermined positions arranged in parallel with the bent portions 911 and 912. In this case, the user can easily form a penetrating portion in which a plurality of packaging parameters can be set in the packaging device 1 by a combination of penetrating portions formed at each of a plurality of predetermined positions on the mount 2. Moreover, the 1st-4th penetration part formed in the 1st-4th predetermined position and the 5th-8th penetration part formed in the 5th-8th predetermined position respectively continued in the conveyance direction. A penetration part can be formed. In this case, the mount 2 can reduce the area of the region in which the penetrating portion is formed on the mount 2 as compared with the case where each penetrating portion is formed on the mount 2 independently. Therefore, the mount 2 can suppress the strength of the mount 2 from being reduced by the first to eighth penetrating portions. In addition, since the size of the region where the perforations 94 and 95 are provided can be suppressed, it is possible to suppress the strength of the mount 2 from being lowered by the perforations 94 and 95 and the penetration portion.

  A predetermined mount position formed by the perforations 94 and 95 of the mount 2 is separated from the sides 901 and 902 of the mount 2. For this reason, the 1st-8th penetration part formed in the mount predetermined position is also separated from the sides 901 and 902 of the mount 2. In this case, the mount 2 can increase the strength of the mount 2 compared to the case where the penetrating portion is provided adjacent to the sides 901 and 902.

<Modification>
The present invention is not limited to the above embodiment, and various modifications can be made. In the above description, the first to fourth through portions formed in the first to fourth predetermined regions of the mount 2 may be detected by the sensor 67 instead of the sensor 4. The sensor 67 includes first to fourth predetermined positions formed at the first to fourth predetermined positions when the first to fourth predetermined positions of the mount 2 pass through the third predetermined conveyance position in the horizontal portion 97A of the conveyance area 97. The fourth through hole may be detected. In this case, the sensor 67 optically detects the presence or absence of the first to fourth penetrating portions, so that the conveyance of the mount 2 is not hindered. For this reason, the packaging apparatus 1 can detect whether the fifth to eighth penetration portions are formed in the first to fourth predetermined regions of the mount 2 while realizing smooth conveyance of the mount 2. Note that when the first to fourth through holes are detected by the sensor 67, the sensor 4 may not be provided.

  Only the perforation 94 is provided in the mount 2, and the perforation 95 may not be provided. On the contrary, only the perforation 95 is provided in the mount 2, and the perforation 94 may not be provided. In these cases, since the area where the perforations are formed can be further reduced, it is possible to more effectively suppress the strength of the mount 2 from being lowered. In addition, when the 1st-4th penetration part is formed in the 1st predetermined position-the 4th predetermined position by the perforation 94 among the bottom face parts 905 of the base_sheet | mounting_paper 2, these penetration parts may be block | closed with the articles | goods 3 The nature is low. On the other hand, in the side surface portion 906 of the mount 2, when the fifth to eighth through portions are formed at the fifth to eighth predetermined positions by the perforation 95, these through portions may be blocked by the article 3. is there. For this reason, it is preferable that the perforation 94 is preferentially formed on the bottom surface portion 905 of the mount 2.

  The number of through portions that can be formed by each of the perforations 95 and 96 of the mount 2 is not limited to four, and may be 1 to 3, 5 or more. Through the perforations 94 and 95 of the mount 2, independent through portions may be formed in the mount 2. The perforations 94 and 95 of the mount 2 may be provided at a position in contact with the side 901. In this case, the first and fifth penetrating portions may be formed in a cutout shape on the side 901 of the mount 2. The packaging device 1 may have a plurality of sensors having the same shape as the sensor 4. These sensors may be arranged in the left-right direction. In this case, the mount 2 may be provided with perforations capable of forming a plurality of through portions arranged in the left-right direction.

  The sensor 4 may not have the spring 43. In this case, the rotating body 41 may be biased in a direction of rotating in the clockwise direction according to the gravity acting on the third portion 41C. The optical element 42B may be provided at a position sandwiching the first portion 41A from the left and right sides.
