In FIG. 9, the casing 800, the bottom portion 10, and the side plate portions 111 and 112 are not shown (the same applies to FIG. 10).

  FIG. 10 shows a state in which the support portion 34 is disposed at the lowest position. In this state, a portion of the support portion 34 that extends in the transport direction is disposed below the transport path 103. A movement path of the guide roller 31 accompanying the movement of the support portion 34 is referred to as a movement path 104. When the guide roller 31 moves to the lowest position along the movement path 104, the guide roller 31 is disposed below the conveyance path 103. A position where the conveyance path 103 and the movement path 104 intersect is referred to as an intersection position 105.

<Cutting part 77>
As shown in FIGS. 9 to 11, a guide rail 74 extending in the left-right direction is provided below the intersection position 105. The guide rail 74 extends to the right side of the conveyance belt 511 and extends to the left side of the conveyance belt 512. The cutting part 77 is connected to the upstream side of the guide rail 74 and is movable along the guide rail 74. The cutting portion 77 includes a blade portion 771 that protrudes upward and extends in the left-right direction. The motor 225 (see FIG. 13) moves the cutting portion 77 in the left-right direction along the guide rail 74.

  As shown in FIG. 10, when the support portion 34 is disposed at the lowest position, the guide roller 31 is disposed above the guide rail 74. A blade portion 771 extending upward from the cutting portion 77 is disposed between the guide roller 31 and the first auxiliary roller 32. When the cutting part 77 is moved in the left-right direction in this state, the blade part 771 can cut the film 24 supplied from the film roll 22 in the width direction.

<Pedestal guide roller 71, holding roller 72, heating unit 86, rotation suppressing unit 80>
As shown in FIGS. 9 to 11, a pedestal guide roller 71 extending in the left-right direction is provided on the upstream side of the portion sandwiched between the side plate portions 111 and 112 (see FIG. 3) and below the conveyance path 103. The pedestal guide roller 71 contacts the conveyance path 103 from below. The pedestal guide roller 71 supports the pedestal 2 (see FIG. 2) conveyed from the upstream side to the downstream side along the conveyance path 103 from below between the cradles 12 and 13, and from the cradle 12 to the cradle 13. Induce. As shown in FIG. 10, when the support portion 34 is disposed at the lowest position, the second auxiliary roller 33 is disposed near the upper portion of the pedestal guide roller 71.

  A holding roller 72 extending in the left-right direction is provided on the downstream side of the pedestal guide roller 71. The left and right end portions of the holding roller 72 are rotatably supported by the holding portion 78. The holding portion 78 can swing around a shaft extending in the left-right direction provided below the pedestal guide roller 71. The holding part 78 is swung by a motor 226 (see FIG. 13). The state in which the holding roller 72 is close to the downstream side of the pedestal guide roller 71 (see FIG. 15) and the state in which the holding roller 72 is separated downward from the pedestal guide roller 71 by the swinging of the holding unit 78 (see FIGS. 9 and 10). To see). When the holding roller 72 comes close to the downstream side of the pedestal guide roller 71, the holding roller 72 contacts the conveyance path 103 from the lower side (see FIG. 12). At this time, the film 24 supplied from the film roll 22 is sandwiched between the holding roller 72 and the pedestal guide roller 71.

  As shown in FIGS. 11 and 12, a heating unit 86 is provided in the vicinity of the downstream side of the holding roller 72. The heating unit 86 includes three heating units at the upper end. The heating unit includes a heater 871 on the upper surface. The heater 871 can heat the film 24 in contact with the film 24. As the motor 223 (see FIG. 13) rotates, the heating unit 86 moves in the vertical direction. With the heating unit 86 disposed at the top (see FIG. 11), the upper surfaces of the three heating units are close to the transport path 103 (see FIGS. 9 and 10). The upper surface of each of the three heating units is separated from the conveyance path 103 in a state where the heating unit 86 moves and is disposed at the lowest position (see FIGS. 9 and 10).

  A rotation suppression unit 80 is provided on the downstream side of the heating unit 86. The rotation suppression unit 80 includes a cam 851, two support rods 82, and a stopper 81. The two support bars 82 extend in the transport direction. The stopper 81 is provided at the upstream end of each of the two support rods 82 and extends in the left-right direction. The shape of the stopper 81 is a bar shape having a square cross-sectional shape. Rubber is provided on the upstream surface of the stopper 81. When the motor 224 (see FIG. 13) rotates the cam 851, the two support bars 82 move in the transport direction, and the stopper 81 also moves in the transport direction.

  In FIG. 12, the support portion 34 is disposed at the lowest position, the pedestal guide roller 71 (see FIG. 10) and the holding roller 72 are close to each other, the heating portion 86 is disposed at the uppermost position, and the stopper 81 is disposed on the upstream side. Indicates the state. The stopper 81 is disposed at a position where it can contact the guide roller 31. The rubber of the stopper 81 pushes the guide roller 31 upstream. Thereby, the rotation of the guide roller 31 is restricted. The heating unit 86 protrudes upward through the space between the first auxiliary roller 32 and the holding roller 72.

<Electrical configuration>
The electrical configuration of the packaging device 1 will be described with reference to FIG. The packaging device 1 includes a CPU 201, a flash ROM 202, a RAM 203, a pedestal mounting sensor 41, a pedestal discharge sensor 42, an operation detection sensor 43, an operation unit 206, a display unit 207, and a heater 871. The CPU 201 controls the entire packaging device 1. The CPU 201 executes a program stored in the flash ROM 202 to execute a process of packaging the article 3 placed on the pedestal 2 with the film 24. The flash ROM 202 stores programs and the like for various processes to be described later executed by the CPU 201.

  The packaging device 1 includes drive units 211 to 217, motors 221 to 227, and encoders 231, 232, and 237. The drive units 211 to 217 drive the motors 221 to 227 by outputting pulse signals to the motors 221 to 227, respectively. The encoders 231, 232, and 237 output a number of pulse signals corresponding to the rotation of the motors 221, 222, and 227, respectively. The CPU 201 is electrically connected to the flash ROM 202, RAM 203, pedestal mounting sensor 41, pedestal ejection sensor 42, operation detection sensor 43, operation unit 206, display unit 207, heater 871, driving units 211 to 217, and encoders 231, 232, and 237. Connect. Drive units 211 to 217 are electrically connected to motors 221 to 227, respectively.

  The CPU 201 can output the first signal and the second signal to an external device connected to the packaging device 1 or an electronic component in the packaging device 1. The first signal is a signal for instructing execution of an operation for restricting the supply of the base 2 to the packaging device 1. The second signal is a signal that instructs execution of an operation for permitting the supply of the base 2 to the packaging device 1. In the present embodiment, the CPU 201 outputs the first signal and the second signal to the gate mechanism 5 connected to the packaging device 1.

<Main processing>
The main process executed by the CPU 201 will be described with reference to FIGS. 15 to 25 show sectional views taken along the line AA in FIG. 2, and the casing 800, the bottom portion 10, and the side plate portions 111 and 112 are not shown. FIGS. 15, 16, and 25 schematically show the first conveyor 4 and the second conveyor 6.

  The main process is a process executed by the CPU 201 in order for the packaging device 1 to package the base 2 and the article 3. Before the main process is executed, the leading end of the film 24 is pulled out from the film roll 22 and is below the transport path 103 and downstream of the pedestal guide roller 71 (see FIG. 12). When the user inputs an instruction to start the main process to the operation unit 206 (see FIG. 1), the CPU 201 starts the main process by reading and executing a program stored in the flash ROM 202.

  As shown in FIG. 14, first, the CPU 201 executes an initialization process (S1). The initialization process is a process for controlling the packaging device 1 to an initial state. As shown in FIG. 12, when the packaging device 1 is in the initial state, the support portion 34 is disposed at the top. The heating unit 86 is disposed at the lowest position. The stopper 81 is disposed on the downstream side. The cutting part 77 is arranged on the left side. The holding roller 72 is disposed at a position close to the base guide roller 71 from the downstream side. The leading end of the film 24 is sandwiched between the holding roller 72 and the pedestal guide roller 71 from both sides in the transport direction. The film 24 is in a state of extending straight in the vertical direction between the upstream side of the second auxiliary roller 33 and the portion sandwiched between the pedestal guide roller 71 and the holding roller 72.

  In S1, the CPU 201 rotates the conveyor belts 511 and 512 to the first standby position or the second standby position described above. In the present embodiment, the CPU 201 rotates the conveyor belts 511 and 512 to the first standby position (see FIG. 15). The CPU 201 outputs a second signal to the control unit of the gate mechanism 5. As shown in FIG. 15, when the control unit of the gate mechanism 5 receives the second signal, it drives the motor of the gate mechanism 5 to move the gate plate 5A to the permitted position. As a result, the gate plate 5 </ b> A is retracted so as not to contact the base 2 supplied from the first conveyor 4 to the packaging device 1.

  After instructing the start of the main process, the user instructs each control unit of the first conveyor 4 and the second conveyor 6 to start the operation. Thereby, the motor of the first conveyor 4 rotates the belt 4A, and the motor of the second conveyor 6 rotates the belt 4A. Thereafter, as shown in FIG. 1, the user places the base 2 on the upper surface of the belt 4 </ b> A, and further places the article 3 on the plate-like portion 905. The pedestal 2 on which the article 3 is placed is conveyed downstream toward the cradle 12 as the belt 4A rotates. As shown in FIG. 15, the pedestal 2 conveyed on the belt 4A moves to the receiving surface 12A through the upper side of the gate plate 5A in the permitted position (arrow 140).

  After execution of S1, the CPU 201 determines whether or not the pedestal mounting sensor 41 is ON (S3). In the example shown in FIG. 15, the first side surface of the base 2 that has moved to the receiving surface 12A is urged by the recesses 612 of the pair of hook claws 61A. At this time, the plate-like portion 905 presses the pedestal mounting sensor 41. That is, the pedestal mounting sensor 41 detects that the pedestal 2 is placed on the receiving surface 12A and the first side surface is in contact with the pair of hook claws 61A. In this case, the CPU 201 determines that the pedestal mounting sensor 41 is ON (S3: YES), and starts to rotate the transport belts 511 and 512 in the forward rotation direction (S5). Thereby, the conveyor belts 511 and 512 change from the standby position to the conveyor position. The conveyance position is a rotation position of the conveyance belts 511 and 512 where the pair of insertion claws 61B or the pair of insertion claws 62B protrude above the receiving surfaces 12A and 13A. When the pedestal mounting sensor 41 is not ON (S3: NO), the CPU 201 returns the process to S3.

  In the example shown in FIG. 15, when the conveyor belts 511 and 512 start to rotate in S5, the pair of hook claws 61A move to the downstream side. At the same time, the pair of insertion claws 61B move to the upper portions of the conveyor belts 511 and 512 along the curved shapes of the pulleys 52B and 53B. At this time, the pair of insertion claws 61B are inserted into the corresponding transport holes 927, respectively. Thereafter, as shown in FIG. 16, as the conveyor belts 511 and 512 rotate, the pair of insertion claws 61 </ b> B inserted into the conveyance holes 927 urges the base 2 toward the downstream side and conveys it.

  After execution of S5, the CPU 201 determines whether or not the pedestal mounting sensor 41 is OFF (S7). In the example shown in FIG. 16, when the pedestal 2 is conveyed downstream by a predetermined amount on the receiving surface 12A, the plate-like portion 905 is separated from the pedestal mounting sensor 41 (arrow 141). In this case, the CPU 201 determines that the pedestal mounting sensor 41 is OFF (S7: YES), and outputs a first signal (S9). In the present embodiment, the CPU 201 outputs the first signal to the control unit of the gate mechanism 5. As shown in FIG. 16, when the control unit of the gate mechanism 5 receives the first signal, it drives the motor of the gate mechanism 5 to move the gate plate 5A to the restriction position. Thereby, supply of the base from the 1st conveyor 4 to the packaging apparatus 1 is interrupted | blocked by the gate board 5A. When the pedestal mounting sensor 41 is not OFF (S7: NO), the CPU 201 returns the process to S7.

  After execution of S9, the CPU 201 drives the motors 221 to 227 (see FIG. 13) via the drive units 211 to 217 (see FIG. 13), thereby executing the packaging process shown in FIGS. As shown in FIG. 17, the motor 222 rotates the conveyor belts 511 and 512 in the forward rotation direction, so that the base 2 is conveyed toward the downstream side (arrow 142). The first side surface of the base 2 contacts the film 24 and then passes over the holding roller 72.

  The pedestal 2 approaches the movement path 104 from the upstream side while pushing the film 24 to the downstream side, and passes above the heating unit 86. Note that the leading end of the film 24 is sandwiched between a pedestal guide roller 71 and a holding roller 72. When the film 24 is pushed downstream by the pedestal 2, the leading end of the film 24 goes around the lower surface of the plate-like portion 905. The film roll 22 rotates in the feeding direction, and the film 24 is fed from the film roll 22. When the film roll 22 rotates, the motor 227 rotates the film roll 22 in the feeding direction.

  When the first side surface of the pedestal 2 moves a predetermined distance downstream from the upper position of the heating unit 86, the motor 222 stops the rotation of the conveyor belts 511 and 512. The pedestal 2 stops. The motor 227 further rotates the film roll 22 in the feeding direction. As a result, the film 24 is forcibly fed out from the film roll 22. As the film roll 22 rotates in the direction of arrow 161, the film 24 relaxes. Thereafter, the motor 227 stops rotating.

  The motor 223 raises the heating unit 86 to the top (arrow 143). The upper surface of the heating unit 86 is close to the conveyance path 103 from below. The first side surface of the pedestal 2 is moved downstream by a predetermined distance from the upper position of the heating unit 86. The film 24 wraps around the lower surface of the plate-like portion 905. Therefore, the upper surface of the heating unit 86 moved to the uppermost position is in a state in which the leading end portion of the film 24 is sandwiched between the lower surface of the plate-like portion 905.

  The heater 871 (see FIG. 12) of the heating unit 86 generates heat. By being heated by the heater 871, the leading end portion of the film 24 is melted and bonded to the downstream end portion of the lower surface of the plate-like portion 905. The heater 871 stops the heat generation after a lapse of a predetermined time from the start of heat generation. The predetermined time is a time required for heating the temperature of the film 24 to the melting point by the heater 871.

  As shown in FIG. 18, the motor 223 lowers the heating unit 86 to the lowest position (arrow 144). The motor 226 swings the holding portion 78 to move the holding roller 72 to a position separated downward from the pedestal guide roller 71 (arrow 145). The pedestal guide roller 71 and the holding roller 72 release the leading end of the film 24. Note that the leading end of the film 24 is in a state of being bonded to the downstream end of the lower surface of the plate-like portion 905.

  The motor 222 restarts the rotation of the transport belts 511 and 512 in the forward rotation direction, and transports the base 2 to the downstream side (arrow 146). The leading end of the film 24 is released from the pedestal guide roller 71 and the holding roller 72. The leading end portion of the film 24 moves downstream as the pedestal 2 moves while being adhered to the lower surface of the plate-like portion 905. As the pedestal 2 moves, the motor 227 rotates the film roll 22 in the feeding direction. The film 24 is further unwound from the film roll 22 (arrow 162). The film 24 is loose.

  The motor 222 continues to rotate the transport belts 511 and 512 in the forward rotation direction, so that the first side surface of the base 2 crosses the intersection position 105 from the upstream side to the downstream side in the transport direction. The base 2 is further conveyed downstream (arrow 146). At this time, the first side surface of the base 2 and the downstream end of the article 3 are brought into contact with the film 24 and bent.

  The first side surface of the base 2 is conveyed to the receiving surface 13A. The first side surface of the base 2 is conveyed to the downstream side of the base guide roller 71. The film 24 is disposed at a position covering the plate-like portion 905 and the upper side of the article 3. After the first side surface of the pedestal 2 crosses the intersection position 105, the motor 222 stops the rotation of the conveyor belts 511 and 512. The pedestal 2 stops. The film 24 extending from the film roll 22 contacts the upstream side of the second auxiliary roller 33 and is slightly guided upstream, contacts the lower side of the second auxiliary roller 33 and extends downstream, and the first auxiliary roller It contacts the lower side of 32 and extends further downstream, reaching the downstream side of the base 2 and the downstream side of the article 3. The guide roller 31 is placed above the film 24 extending between the first auxiliary roller 32 and the base 2 and the article 3.

  As shown in FIG. 19, after the pedestal 2 stops, the motor 221 moves the support portion 34 along the movement path 104 from the highest level to the lowest level. As the support portion 34 moves to the lowest position, the guide roller 31 contacts the film 24 from above, and further guides the film 24 downward along the movement path 104 (arrow 147). The film 24 presses the base 2 and the article 3 from above. While the support portion 34 moves to the lowest position, the motor 227 rotates the film 24 in the feeding direction. The film 24 is fed out from the film roll 22 (arrow 163). Accordingly, the film 24 is loose. Thereafter, the motor 227 stops rotating.

  As shown in FIG. 20, the guide roller 31 that has moved to the lowest position is in contact with the transport path 103 from below. The film 24 covers the downstream side, the upper side, and the upstream side of the plate-like portion 905 and the article 3. The motor 227 rotates the film roll 22 in the winding direction. The winding direction is the direction opposite to the feeding direction. As a result, the film 24 fed out from the film roll 22 is forcibly wound around the film roll 22 (arrow 164).

  The motor 222 rotates the conveyor belts 511 and 512 in the reverse direction. The reverse rotation direction is a direction in which the conveyor belts 511 and 512 rotate clockwise as viewed from the right side. The insertion claw 61B of the first claw portion 61 moves from the downstream side to the upstream side, and conveys the base 2 toward the upstream side (arrow 148). The second side surface of the base 2 contacts the film 24 and pushes it upstream. The second side surface of the pedestal 2 crosses the intersection position 105 from the downstream side toward the upstream side and passes through the upper position of the heating unit 86.

  The guide roller 31 moves relatively to the downstream side with respect to the pedestal 2 while in contact with the lower surface of the plate-like portion 905 from below. The film 24 is sandwiched between the lower surface of the plate-like portion 905 and the guide roller 31. The film 24 goes around to the lower side of the base 2. When the second side surface of the pedestal 2 moves a predetermined distance upstream from the position above the heating unit 86, the motor 222 stops driving and stops the pedestal 2.

  When the base 2 is transported upstream, the motor 227 rotates the film roll 22 in the winding direction. The film 24 is wound on a film roll 22. Accordingly, the pedestal 2 is conveyed to the upstream side, and tension is applied to the film 24 when the upstream end of the plate-like portion 905 pushes the film 24 to the upstream side. Due to the tension acting on the film 24, the film 24 adheres to the base 2 and the article 3.

  As shown in FIG. 21, the motor 224 moves the stopper 81 upstream (arrow 149). On the upstream side of the stopper 81, the guide roller 31 that has moved to the lowest position is disposed. The rubber of the stopper 81 is close to the guide roller 31 and sandwiches the film 24 wound around the guide roller 31 between the guide roller 31 and the rubber. The film 24 is sandwiched between the guide roller 31 and the rubber of the stopper 81. The rotation of the guide roller 31 is restricted. Thereafter, the motor 227 stops driving and stops the rotation of the film roll 22 in the winding direction.

  The motor 225 moves the cutting part 77 from the left side to the right side along the guide rail 74 (see FIG. 11). When the cutting portion 77 moves to the right side, the film 24 is cut by the blade portion 771 on the film roll 22 side from the portion sandwiched between the guide roller 31 and the rubber of the stopper 81. The cutting part 77 cuts off the part of the film 24 that covers the base 2 and the article 3 from the film roll 22 side. After the film 24 is cut, the cut end of the film 24 extending from the film roll 22 hangs down below the pedestal guide roller 71 (see FIG. 22).

  As shown in FIG. 22, the motor 226 swings the holding portion 78 to move the holding roller 72 to a position close to the base guide roller 71 from the downstream side (arrow 150). An end portion of the film 24 cut by the cutting portion 77 is sandwiched between the pedestal guide roller 71 and the holding roller 72.

  The motor 223 raises the heating unit 86 from the lowest position to the highest position (arrow 151). The upper surface of the heating unit 86 is close to the conveyance path 103 from below. Note that the upstream end surface of the plate-like portion 905 has moved upstream by a predetermined distance from the position above the heating portion 86. At the upstream end of the lower surface of the plate-like portion 905, the film 24 guided by the guide roller 31 is disposed. Therefore, when the heating unit 86 is raised and disposed at the uppermost position, the upper surface of the heating unit 86 is in a state where the film 24 is sandwiched between the base 2 and the upper surface.

  The heater 871 of the heating unit 86 generates heat and heats the end portion of the film 24 cut by the cutting unit 77. The film 24 melts. The melted film 24 is bonded to the upstream end of the lower surface of the plate-like portion 905. The film 24 cut from the film roll 22 is in a state of covering the base 2 and the article 3. The base 2 and the article 3 are packaged. The heater 871 stops generating heat after a predetermined time has elapsed.

  As shown in FIG. 23, the motor 223 lowers the heating unit 86 from the top to the bottom (arrow 152). The upper surface of the heating unit 86 is separated from the conveyance path 103. The motor 224 moves the stopper 81 downstream (arrow 153). The rubber provided on the stopper 81 is separated from the guide roller 31. The guide roller 31 is in a rotatable state. Thereafter, the motor 222 rotates the conveyor belts 511 and 512 in the forward rotation direction, and conveys the base 2 to the downstream side. Thereby, the base 2 after packaging is conveyed downstream toward the receiving tray 13, and the packaging process is completed.

  After execution of S11, the CPU 201 determines whether or not the pedestal ejection sensor 42 is ON (S13). In the example shown in FIG. 24, the pedestal 2 after packaging is conveyed downstream on the receiving surface 13A as the conveying belts 511 and 512 rotate in the forward direction (arrow 154). When the pedestal 2 after packaging is conveyed to the downstream end of the receiving surface 13 </ b> A, the plate-like portion 905 presses the pedestal discharge sensor 42. In this case, the CPU 201 determines that the pedestal ejection sensor 42 is ON (S13: YES), and rotates the conveyor belts 511 and 512 in the forward direction to the standby position (S15). When the base discharge sensor 42 is not ON (S13: NO), the CPU 201 returns the process to S13.

  In S15, when the first claw portion 61 (specifically, the pair of insertion claws 61B) transports the base 2 in S11, the transport belts 511 and 512 are rotated to the second standby position. On the other hand, when the second claw portion 62 (specifically, the pair of insertion claws 62B) conveys the base 2 in S11, the conveyance belts 511 and 512 are rotated to the first standby position. In the example shown in FIG. 24, the conveyor belts 511 and 512 are rotated to the second standby position. At this time, the pair of hook claws 61A and the pair of insertion claws 61B move to the lower side of the receiving surfaces 12A and 13A along the curved shapes of the pulleys 52A and 53A. The pair of insertion claws 61 </ b> B come out of the corresponding transfer holes 927 and are separated from the base 2. The pedestal 2 stops at the downstream portion of the receiving surface 13A.

  Next, the CPU 201 outputs a second signal (S17). In the present embodiment, the CPU 201 outputs the second signal to the control unit of the gate mechanism 5. As a result, as shown in FIG. 16, the gate plate 5A moves from the restricted position to the permitted position. Thereafter, the CPU 201 returns the process to S3. Accordingly, the user can package the base 2 and the article 3 in the same manner as described above by placing the new base 2 on the upper surface of the belt 4A and placing the article 3 on the plate-like portion 905.

  When packaging processing (S11) of a new pedestal 2 is started in a state where the pedestal 2 after packaging is placed on the receiving surface 13A, the pedestal 2 after packaging is conveyed to the second conveyor 6 as follows. The In the example shown in FIG. 25, when the packaging process is executed as in FIG. 17, the pedestal 2 is conveyed toward the downstream side (arrow 142). At this time, the pair of pushing claws 61C located on the downstream side of the pair of hook claws 62A contact the second side surface of the pedestal 2 on the receiving surface 13A to urge the pedestal 2 to the downstream side. The biased pedestal 2 moves from the receiving surface 13A to the belt 6A and is further conveyed downstream by the belt 6A (arrow 155). Therefore, the packaging system 100 according to the present embodiment can supply the pedestal 2 before packaging to the packaging device 1 and collect the pedestal 2 after packaging from the packaging device 1 by controlling the rotation of the conveyor belts 511 and 512. .

<Exemplary effects of embodiment>
The packaging device 1 or the packaging system 100 according to the embodiment has the following operational effects. The following functions and effects are as follows: a pair of hook claws 61A, a pair of insertion claws 61B, a pair of extrusion claws 61C, and a first standby position, respectively, a pair of hook claws 62A, a pair of insertion claws 62B, and a pair of extrusion claws 62C. It goes without saying that the same effect can be obtained even if the second standby position is used.

  In the packaging device 1 of the above embodiment, when the conveyor belts 511 and 512 are in the first standby position, the base 2 is placed on the receiving surface 12A by the base mounting sensor 41, and the first side surface of the base 2 is a pair of When it is detected that the hook claw 61A is touched, the conveyor belts 511 and 512 are rotated by the motor 222 so as to move from the first standby position to the conveyance position. After inserting the pair of insertion claws 61B into the holes 927 of the base 2 placed on the receiving surface 12A, the conveyor belts 511 and 512 are further rotated by the motor 222 (S3: YES, S5). When the pedestal 2 is conveyed to the inside of the housing 800 by the pair of insertion claws 61B, the article 3 placed on the pedestal 2 is packaged by the film 24 together with the pedestal 2 (S11). According to this, if the base 2 is placed on the receiving surface 12A and the first side surface of the base 2 comes into contact with the pair of hook claws 61A, the base 2 is automatically conveyed by the pair of insertion claws 61B. Therefore, the user can easily attach the pedestal 2 to the pair of insertion claws 61 </ b> B, which are conveying members.

  After the pedestal 2 is received by the pair of insertion claws 61 </ b> B and conveyed downstream on the surfaces 12 </ b> A and 13 </ b> A, the conveyance belts 511 and 512 are further rotated by the motor 222. Thereby, the pair of hook claws 61A and the pair of insertion claws 61B are moved below the receiving surfaces 12A and 13A, and the second side surface of the pedestal 2 is urged downstream by the pair of pushing claws 61C ( S11). Accordingly, the packaging device 1 can supply the pedestal 2 before packaging to the packaging position, and can transport the pedestal 2 after packaging to the outside of the packaging device 1.

  The pair of insertion claws 61 </ b> B has a shape in which a cross-sectional area in a direction perpendicular to the outer direction of the conveyor belts 511 and 512 gradually decreases toward the outer side of the conveyor belts 511 and 512. That is, the pair of insertion claws 61 </ b> B has a shape that can be easily inserted into the hole 927 of the base 2. Therefore, the packaging device 1 can reliably convey the base 2 by the pair of insertion claws 61B.

  The pedestal mounting sensor 41 is provided between the movable range of the left hook claw 61A and the movable range of the right hook claw 61A in the receiving surface 12A. Therefore, the packaging device 1 can reliably detect the pedestal 2 contacting the pair of hook claws 61 </ b> A by the pedestal mounting sensor 41.

  When the conveyor belts 511 and 512 are in the first standby position, the pedestal mounting sensor 41 is on the imaginary line connecting the pair of hook claws 61A or on the upstream side of the imaginary line. Therefore, the packaging device 1 can reliably detect the base 2 that contacts the pair of hook claws 61 </ b> A from the upstream side by the base mounting sensor 41.

  The first signal is output when the state is changed from the state in which the object is detected by the pedestal mounting sensor 41 to the state in which the object is not detected by the pedestal mounting sensor 41 (S9). Therefore, the packaging device 1 can execute various operations in the packaging device 1 or other devices in accordance with changes in the detection state of the pedestal mounting sensor 41.

  The control unit of the gate mechanism 5 moves the gate plate 5A to the permitted position when the first signal is not received (for example, when the second signal is received), and when the first signal is received, the gate plate 5A. Is moved to the restriction position. Therefore, the packaging system 100 can permit or regulate the supply of the pedestal 2 to the packaging device 1 according to the change in the detection state of the pedestal mounting sensor 41.

  Since the packaging system 100 includes the first conveyor 4, the base 2 before packaging can be supplied to the packaging device 1 from the upstream side of the packaging device 1. By providing the second conveyor 6, the packaging system 100 can transport the pedestal 2 after packaging in a direction away from the packaging device 1.

<Example of modification>
The present invention is not limited to the above embodiment, and various modifications can be made. The packaging device 1 may be used alone. The packaging system 100 may not include at least one of the first conveyor 4, the gate mechanism 5, and the second conveyor 6. For example, when the packaging device 1 is used alone, or when the packaging system 100 does not include the first conveyor 4, the user manually operates the first side surface of the base 2 so as to contact the pair of hook claws 61A. The pedestal 2 may be placed on the receiving surface 12A.

  When the control unit of the first conveyor 4 does not receive the first signal (for example, when the second signal is received), the belt 4A is rotated to convey the base 2 and the first signal is received. The rotation of the belt 4A may be stopped (that is, the conveyance of the pedestal 2 is stopped). When the first signal is not received (for example, when the second signal is received), the CPU 201 of the packaging device 1 executes a notification permitting the supply of the pedestal 2 and receives the first supply signal of the pedestal 2. In this case, a notification for prohibiting the supply of the base 2 may be executed. Examples of the notification mode for permitting or prohibiting the supply of the base 2 include light emission control, image display, and audio output.

  The CPU 201 may not execute S13. In this case, the CPU 201 may output a second signal when it is detected by a sensor (not shown) that the conveyor belts 511 and 512 have rotated to the first standby position or the second standby position.

  In the said embodiment, the case where the packaging system 100 was comprised with the some apparatus (The packaging apparatus 1, the 1st conveyor 4, the gate mechanism 5, and the 2nd conveyor 6) mutually independent was illustrated. Instead of this, the packaging device 1 may include at least one of the first conveyor 4, the gate mechanism 5, and the second conveyor 6. The CPU 201 of the packaging device 1 may directly control at least one operation of the gate plate 5A, the belt 4A, and the belt 6A.

  The pedestal mounting sensor 41 only needs to be able to detect directly or indirectly that the pedestal 2 is placed on the receiving surface 12A and the first side surface of the pedestal 2 is in contact with the pair of hook claws 61A. For example, the pedestal mounting sensor 41 may be an optical sensor. In the above embodiment, the case where two claw portions (the first claw portion 61 and the second claw portion 62) are provided on the conveyor belts 511 and 512 is illustrated, but one or three claw portions are provided on the conveyor belts 511 and 512.
