It protrudes from the right end to the outside in the left-right direction. Hereinafter, a portion surrounded by the pair of first side surface cuts 931 and second side surface cuts 932 is referred to as a “side protrusion 936”. The side protrusions 936 are substantially perpendicular to the second plate-like portions 906 and 907 when viewed along the transport direction. Hereinafter, in each of the side protrusions 936, the bent portions 911 and 912 are also referred to as “proximal end”, and the opposite side is also referred to as “distal end”. The cause piece 945 and the cause piece 949 of the cause part 940 can be caused to be parallel to the first side 901 and the second side 902. That is, the raising piece 945 and the raising piece 949 can be caused in a direction perpendicular to the conveying direction of the base 2.

  As shown in FIG. 7, when the plate-like portion 90 is bent, the plurality of peak portions 974 and valley portions 975 extend in the left-right direction inside the first plate-like portion 905 and each side surface protruding portion 936.

The base 2 is not easily deformed. Moreover, in each side surface protrusion part 936, the some peak part 974 and trough part 975 are extended in the left-right direction from the base end side to the front end side. Even within the first plate-shaped portion 905, the plurality of peak portions 974 and valley portions 975 extend in the left-right direction. Therefore, the load applied to the first plate-shaped portion 905 in the left-right direction is dispersed by the plurality of peak portions 974 and valley portions 975. The base 2 is not easily deformed. Therefore, the base 2 can improve the load resistance in the left-right direction.

  Further, the extending direction of the second side surface cut 932 and the bent portions 911 and 912 is orthogonal to the extending direction of the plurality of peak portions 974 and valley portions 975. Even when a load is applied in the left-right direction with respect to each side protrusion 936 and the first plate-like part 905, the load is in a direction in which the plurality of peaks 974 and valleys 975 are compressed inward in the left-right direction.

Therefore, the base 2 can improve the load resistance in the conveyance direction.

  Within each bottom projection 926, the plurality of peaks 974 and valleys 975 extend vertically from the proximal side to the distal side (see FIG. 9). Even when an article 3 (see FIG. 17) is placed on the first plate-like portion 905 and the load is applied to the bottom surface protruding portions 926 in the vertical direction, the load is a plurality of peak portions 974 and valleys. Distributed to the portion 975. Moreover, also in the inside of the 2nd plate-shaped parts 906 and 907, the some peak part 974 and trough part 975 are extended in an up-down direction (refer FIG. 9). Even when a load is applied to the second plate-like portions 906 and 907 in the vertical direction, the load is distributed to the plurality of peak portions 974 and valley portions 975. The base 2 is not easily deformed. Therefore, the base 2 can improve the load resistance in the vertical direction.

  Furthermore, each 2nd bottom face cut | interruption 922, the some peak part 974, and the trough part 975 are orthogonal to the bending parts 911 and 912, respectively. By placing the article 3 on the first plate-like portion 905, the load acting on the inside of the base 2 from the front end portion of each bottom surface protruding portion 926 is a plurality of crest portions 974 and trough portions inside each bottom surface protruding portion 926. It is easy to face the direction in which 975 is compressed inward in the vertical direction. Similarly, the load acting on the inside of the pedestal 2 from the tip of the side protrusion 936 tends to be directed in the direction in which the plurality of peak portions 974 and valley portions 975 are compressed inward in the vertical direction. The plurality of peak portions 974 and valley portions 975 are not easily bent. Therefore, the base 2 can further improve the load resistance in the vertical direction.

  As shown in FIG. 7, the first plate-like portion 905 is formed with two holes 927 each surrounded by a pair of first bottom surface cuts 921 and third bottom surface cuts 923 at each of the bent portions 911 and 912.

It becomes. The SP value (solubility parameter) represents the strength at which a certain molecular aggregate gathers (strength of intermolecular force). When the SP value is close, the strength of the intermolecular force is close. Even if different substances have similar SP values, the strength of intermolecular force is also similar, and the intermolecular forces are close to each other. As a result, the closer the SP value, the better the mixture, the better the paint, and the better the joint. Therefore, a hot-melt adhesive that can be welded may be appropriately selected according to the wrapping film 24 to be used. For example, for a polyethylene film, a polyolefin-based hot melt adhesive is used. As a method for bonding the film 24 and the hot melt adhesive, high frequency welding, heat welding, ultrasonic welding, or the like can be used.

  Next, with reference to FIG. 29, the application method of the hot-melt-adhesive to the adhesive application part 97 and the anti-slip | skid part 925 is demonstrated. In the left column of FIG. 29, the top row is a bead 161, and the hot melt adhesive is applied in a linear shape (bead shape). The bead diameter can be freely changed by various nozzle diameters.

In order for the user to fit the first side 901 of the first plate-like portion 905 of the base 2 into the space sandwiched between the first extending portion 612 and the belt 51 in the first transport portion 61, the upstream The base 2 is moved obliquely downward from the side toward the downstream side. The first side 901 of the first plate-like portion 905 of the base 2 moves obliquely downward from the upstream side toward the downstream side, and enters the space sandwiched between the first extending portion 612 and the belt 51. To do. As shown in FIG. 14, the first side 901 contacts the first protruding portion 611 and applies a force to the first protruding portion 611 on the downstream side. Further, the first plate-like portion 905 of the pedestal 2 contacts the first extending portion 612 from below, and applies an upward force to the first extending portion 612. The protruding direction of the first protruding portion 611 is inclined downstream with the claw portion 613 as a fulcrum. The downstream end of the first protrusion 611 moves to the inside of the belt 51, and the belt 51 is elastically deformed and bent inward. A length S between the end portion of the first extending portion 612 on the belt 51 side and a plane parallel to the receiving surface (conveying path 103) is increased. For this reason, the first plate-like portion 905 of the base 2 smoothly enters the space sandwiched between the first extending portion 612 and the belt 51. The second side 902 of the pedestal 2 is pushed downward, and the first plate-like portion 905 of the pedestal 2 becomes parallel to the receiving surface. In addition, since the corner | angular part 624 of the 2nd extension part 622 of the 2nd conveyance part 62 is curving in circular arc shape, the base 2 is pushed down smoothly, without being caught by the corner | angular part 624. FIG.

  As shown in FIG. 13, the first side 901 of the pedestal 2 fits in a space sandwiched between the first extending portion 612 and the belt 51. The first extending portion 612 is in a state of covering the first side 901 of the first plate-like portion 905 of the base 2 from above. Since the first transport unit 61 is provided on the belt 51 arranged on both the left and right side surfaces of the cradle 13, the first side 901 of the first plate-like portion 905 of the base 2 is the left and right side portions, and the first extension It is in a state of being sandwiched between the space between the installation portion 612 and the belt 51.

  The distance between the 1st protrusion part 611 of the 1st conveyance part 61 and the 2nd protrusion part 621 of the 2nd conveyance part 62 is the 1st edge | side 901 of the base 2, and the bottom face part 92 close | similar to the 1st edge | side 901. Slightly longer than the length between. The second protrusion 621 of the second transport unit 62 fits into a hole 927 surrounded by a cut in the bottom surface 92 of the base 2 (a pair of first bottom cut 921 and third bottom cut 923). The pedestal 2 moves slightly horizontally to the upstream side along a plane parallel to the receiving surface. The downstream side of the pair of first bottom surface cuts 921 enters a space sandwiched between the second extending portion 622 and the belt 51. The downstream side of the pair of first bottom surface cuts 921 fits into the space. The second extending portion 622 is in a state where the downstream side of the pair of first bottom surface cuts 921 is covered from above.

  The pedestal 2 is sandwiched between the first protruding portion 611 of the first conveying portion 61 and the second protruding portion 621 of the second conveying portion 62 from both sides in the conveying direction. Since the 2nd conveyance part 62 is provided in the belt 51 arrange | positioned on the right-and-left both sides | surfaces of the receiving stand 13, the base 2 is a 1st protrusion part 611 of the 1st conveyance part 61, and 2nd conveyance by the right-and-left both sides part. It will be in the state pinched | interposed between the 2nd protrusion part 621 of the part 62. FIG.

  Although not shown, since the first plate-like portion 905 of the pedestal 2 is in contact with the receiving surface of the cradle 13, the bottom surface protruding portion 926 that protrudes downward from the first plate-like portion 905 is a receiving portion. It protrudes downward from the left and right sides of the receiving surface of the base 13 and is disposed outside the left and right side surfaces of the receiving base 13.

  The electrical configuration of the packaging device 1 will be described with reference to FIG. The packaging device 1 includes a CPU 201, a ROM 202, a RAM 203, a sensor 204, an input unit 205, and a heater 411. The CPU 201 controls the entire packaging device 1. The CPU 201 executes a program stored in the ROM 202 to execute a process (packaging process) for packaging the article 3 placed on the base 2 with the film 24. The ROM 202 stores a packaging process program executed by the CPU 201. The RAM 203 stores temporary data. The sensor 204 detects a reflecting plate provided on the outer surface of the belt 51. The input unit 205 is a plurality of input buttons that allow the user to perform an input operation on the packaging device 1. The packaging device 1 includes drive units 211 to 216, a first motor 221, a second motor 222, a third motor 223, a fourth motor 224, a fifth motor 225, and a sixth motor 226. The drive units 211 to 216 drive the first motor 221 to the sixth motor 226, respectively. The CPU 201 is electrically connected to the ROM 202, RAM 203, sensor 204, heater 411, and drive units 211 to 216. The drive units 211 to 216 are electrically connected to the first motor 221 to the sixth motor 226, respectively.

  The packaging process executed by the CPU 201 of the packaging device 1 will be described with reference to FIGS. Before performing the operation of packaging the pedestal 2 and the article 3 with the film 24 using the packaging device 1, the user receives the receiving surface so that the receiving surfaces of the receiving table 12 and the receiving table 13 (see FIG. 1) are horizontal. The base 12 and the cradle 13 are swung. The receiving surface of the receiving tray 12 and the receiving surface of the receiving tray 13 form a transport path 103. First, the user ranges from the mark 951 to the mark 956 of the first plate-like part 905 of the base 2, the mark 957 to the mark 959 of the second plate-like part 906, and the mark 961 to the mark of the second plate-like part 907. The article 3 is placed on the anti-slip portion 925 so as to fall within the height range of 963. Next, the user turns on the power of the packaging device 1. When power is turned on to the packaging device 1, the CPU 201 starts the packaging process by reading and executing the program stored in the ROM 202.

  The CPU 201 initializes the state of the packaging device 1 (S11). Specifically, it is as follows. The CPU 201 drives the first motor 221 by controlling the drive unit 211 to raise the support unit 34 and arrange it at the uppermost position. Accordingly, the movable roller 30 (the guide roller 31, the first auxiliary roller 32, and the second auxiliary roller 33) supported by the support portion 34 is disposed at the uppermost position (see FIG. 17). The CPU 201 drives the second motor 222 by controlling the drive unit 212 to rotate the belt 51 (see FIG. 2) of the transport mechanism 50. When the sensor 204 detects the reflecting plate, the CPU 201 controls the driving unit 212 to stop driving the second motor 222. Thus, the transport unit 60 (the first transport unit 61 and the second transport unit 62) is projected upward from the receiving surface of the cradle 12 (see FIG. 1). The packaging device 1 is in a state in which the user can set the base 2 on the receiving surface of the receiving base 12.

  The CPU 201 controls the driving unit 213 to drive the third motor 223, and lowers the heating unit 40 and arranges it at the lowest position. As a result, the heating unit 40 is separated from the transport path 103 (see FIG. 17). The lid 46 is in a substantially horizontal state and covers the heating unit 40 from above. For this reason, when the user tries to touch the inside of the packaging device 1 for maintenance, the user cannot directly contact the heater 411 of the heating unit 40.

  The CPU 201 controls the drive unit 214 to drive the fourth motor 224 to move the stopper 81 downstream (see FIG. 17). The CPU 201 controls the drive unit 215 to drive the fifth motor 225 to move the cutting unit 77 to the left side (see FIG. 17). In this state, the horizontal position of the blade portion 771 of the cutting portion 77 is arranged on the left side of the left end portion of the film 24 accommodated in the film cassette 21. The CPU 201 controls the driving unit 216 to drive the sixth motor 226 to swing the holding unit 78. The holding roller 72 is in a state of being separated downward with respect to the base guide roller 71.

  CPU201 judges whether the instruction | indication which starts the packaging by the film 24 of the base 2 and the articles | goods 3 was input via the input part 205 (refer FIG. 15) (S12). If no packaging start instruction has been input (S12: NO), the process returns to S12. The CPU 201 continues to wait for input of a start instruction.

  The user manually draws out the film 24 discharged from the film discharge port of the film cassette 21 downward through the upstream side of the second auxiliary roller 33 after the packaging apparatus 1 is initialized in S11. The film 24 is guided slightly upstream by contacting the upstream side of the second auxiliary roller 33. The user pulls the leading end of the film 24 drawn downward to the lower side of the conveyance path 103 and arranges it on the downstream side of the pedestal guide roller 71 (see FIG. 17).

  The user performs an input operation for notifying the packaging device 1 that the film 24 is ready via the input unit 205. The CPU 201 controls the driving unit 216 to drive the sixth motor 226 to swing the holding unit 78. As the holding portion 78 swings, the holding roller 72 is disposed close to the downstream side of the base guide roller 71 as shown in FIG. The leading end of the film 24 drawn out from the film cassette 21 is sandwiched from both sides in the transport direction by the pedestal guide roller 71 and the holding roller 72. The film 24 and the transport path 103 intersect in the vicinity of the front end of the film 24. Torque is applied to the film roll 22 by a clutch spring and tension is applied to the film 24, so that the film 24 is sandwiched between the upstream side of the second auxiliary roller 33, the base guide roller 71 and the holding roller 72. It will be in the state extended straight in the up-down direction between the parts.

  The user places the pedestal 2 on the cradle 13 (see FIGS. 12 to 14). The pedestal 2 is positioned by the transport unit 60 and the position with respect to the transport unit 60 is fixed. The first side 901 of the first plate-like portion 905 of the base 2 is disposed on the downstream side, and the second side 902 is disposed on the upstream side. The pedestal 2 is in a state that can be transported in the transport direction by the transport unit 60. The user places the article 3 on the first plate-like portion 905 of the base 2 placed on the cradle 13. The user performs an input operation for instructing the start of packaging of the base 2 and the article 3 with the film 24 via the input unit 205.

  As shown in FIG. 16, when an instruction to start packaging is input (S12: YES), the CPU 201 controls the drive unit 212 to drive the second motor 222. The CPU 201 adjusts the rotation direction of the second motor 222 by controlling the drive unit 212 so that the belt 51 rotates in the direction in which the pedestal 2 is conveyed from the upstream side to the downstream side. The second motor 222 rotates the belt 51. The belt 51 has a direction in which the transport unit 60 (the first transport unit 61 and the second transport unit 62) protruding upward from the receiving surface of the third receiving tray 13 moves from the upstream side to the downstream side (indicated by the arrow 141 in FIG. 17). Direction). The transport unit 60 transports the base 2 from the upstream side to the downstream side along the transport path 103 (S13).

  The first protrusion 611 of the first transport part 61 and the second protrusion 621 of the second transport part 62 are close to the first side 901 and the first side 901 of the first plate-like part 905 of the base 2. A portion between the holes 927 is sandwiched from both sides in the transport direction. For this reason, the conveyance part 60 can convey the base 2 appropriately downstream.

  Hereinafter, the rotation direction of the second motor 222 and the belt 51 when the pedestal 2 is transported from the upstream side to the downstream side is referred to as “forward direction”, and the rotation direction opposite to the forward direction is referred to as “reverse direction”.

  As shown in FIG. 17, the downstream end of the base 2 gradually approaches the film 24 extending in the vertical direction. As shown in FIG. 18, the downstream end portion (first side 901) of the first plate-like portion 905 of the pedestal 2 contacts the film 24 and then passes over the holding roller 72. The CPU 201 controls the driving unit 212 to continuously drive the second motor 222 and continuously rotate the belt 51 in the forward direction. The pedestal 2 is continuously conveyed downstream.

  As shown in FIG. 18, when the base 2 moves downstream (arrow 142), the first side 901 of the first plate-like portion 905 of the base 2 pushes the film 24 downstream. The pedestal 2 moves further downstream. The first side 901 of the first plate-like portion 905 of the base 2 approaches the movement path 104 from the upstream side. The pedestal 2 moves further downstream, and the first side 901 of the first plate-like portion 905 of the pedestal 2 passes above the heating unit 40. The leading end of the film 24 is sandwiched between the pedestal guide roller 71 and the holding roller 72. When the film 24 is pushed downstream by the first side 901 of the first plate-like portion 905 of the pedestal 2, the leading end of the film 24 goes around the lower surface of the first plate-like portion 905 of the pedestal 2.

  The CPU 201 determines that the first side 901 of the first plate-like portion 905 of the pedestal 2 has moved downstream by a predetermined distance with respect to the upper position of the heating unit 40 in S13 (see FIG. 16), on the downstream side of the pedestal 2. It is detected based on the number of rotations of the second motor 222 after the start of the conveyance to the vehicle. The predetermined distance is substantially the same as the distance from the first side 901 of the first plate-like portion 905 to the first straight line 981 (see FIG. 11). When the first side 901 of the first plate-like portion 905 of the pedestal 2 moves a predetermined distance downstream from the upper position of the heating unit 40, the CPU 201 controls the drive unit 212 as shown in FIG. Then, the driving of the second motor 222 is stopped, and the conveyance to the downstream side of the base 2 is stopped (S15).

  CPU201 controls actuator 213, drives third motor 223, and raises heating part 40 (S17). After the heating unit 40 is placed in the uppermost position, the CPU 201 controls the drive unit 213 to stop driving the third motor 223 and stop the heating unit 40 from rising. As shown in FIG. 19, when the heating unit 40 rises to the top (arrow 143), the upper surface of the heating unit 40 is close to the transport path 103 from below. The support part 414 sandwiches the film 24 between the base 2 and fixes the position of the heater 411 with respect to the film 24. As the heating unit 40 is raised, the lid 46 is in a substantially vertical state against the urging force of a spring (not shown).

  The first side 901 of the first plate-like portion 905 of the base 2 is moved downstream by a predetermined distance from the upper position of the heating unit 40. Further, the film 24 wraps around the lower surface of the first plate-like portion 905 of the pedestal 2. For this reason, in a state where the heating unit 40 is disposed at the uppermost position, the upper surface of the heating unit 40 is in a state where the film 24 is sandwiched between the lower surface of the first plate-like portion 905 of the base 2. Here, as shown in FIG. 11, a first adhesive application portion 971 is affixed between the first side 901 and the first straight line 981 on the lower surface of the first plate-like portion 905 of the base 2. For this reason, the upper surface of the heating unit 40 moved to the top is in a state in which the film 24 is sandwiched between the upper surface of the heating unit 40 and the first adhesive application unit 971 attached to the base 2.

  As shown in FIG. 16, the CPU 201 heats the heater 411 of the heating unit 40 (S19). The heater 411 heats the film 24 and melts the film 24. At the same time, the heater 411 heats the first adhesive application part 971 affixed to the base 2 through the film 24 and melts the hot melt adhesive of the first adhesive application part 971. The melted film 24 and the hot melt adhesive of the first adhesive application part 971 adhere well. Thereby, the front end of the film 24 is bonded to the vicinity of the first side 901 in the lower surface of the first plate-like portion 905 of the base 2 through the hot melt adhesive of the first adhesive application portion 971 (S19).

  The CPU 201 stops the heating of the heater 411 after a predetermined time has elapsed since the heating of the heater 411 was started in S19 (S20). The predetermined time is a time necessary for heating the temperature of the hot melt adhesive of the film 24 and the first adhesive application part 971 to the melting point by the heater 411. CPU201 controls actuator 213, drives third motor 223, and lowers heating part 40 (S21). The upper surface of the heating unit 40 is separated from the conveyance path 103. After the heating unit 40 is disposed at the lowest position, the CPU 201 controls the driving unit 213 to stop driving the third motor 223 and stop the lowering of the heating unit 40. As shown in FIG. 20, when the heating part 40 is lowered to the lowest position (arrow 144), the lid part 46 becomes substantially horizontal by the urging force of a spring (not shown). The upper surface of the heating unit 40 is covered with the lid 46.

  As shown in FIG. 16, the CPU 201 controls the drive unit 216 to drive the sixth motor 226 to swing the holding unit 78 (S23). As shown in FIG. 20, when the holding portion 78 swings in the direction of the arrow 145, the holding roller 72 is separated from the pedestal guide roller 71 downward. The pedestal guide roller 71 and the holding roller 72 release the front end of the sandwiched film 24. Note that the leading end of the film 24 is melted by the heater 411 heated in S <b> 19 and adhered to the hot melt adhesive of the first adhesive application part 971 on the lower surface of the base 2. As shown in FIG. 16, the CPU 201 controls the drive unit 212 to drive the second motor 222, rotates the belt 51 in the forward direction, and conveys the base 2 to the downstream side (S25).

  As shown in FIG. 20, the transport unit 60 moves from the upstream side to the downstream side along the transport path 103 (arrow 146), and transports the pedestal 2 to the downstream side. Since the leading end of the film 24 is released from the pedestal guide roller 71 and the holding roller 72, the leading end of the film 24 moves downstream as the pedestal 2 moves while being adhered to the lower surface of the pedestal 2. The first side 901 of the first plate-like portion 905 of the pedestal 2 crosses the position where the transport path 103 and the movement path 104 intersect (intersection position 105) from the upstream side toward the downstream side. The pedestal 2 moves further downstream (arrow 146). As the pedestal 2 moves downstream, the first side 901 of the first plate-like portion 905 of the pedestal 2 and the downstream end of the article 3 are pressed against the film 24. The film 24 is bent at the contact portion between the first side 901 of the first plate-like portion 905 of the base 2 and the article 3. The film 24 is fed out from the film roll 22 little by little. The film 24 is strongly pressed against the base 2 and the article 3 by the torque applied to the film roll 22. The film 24 is in close contact with the pedestal 2 and the article 3 at a position covering the first plate-like portion 905 of the pedestal 2 and the downstream side of the article 3.

  At this time, since the article 3 is placed on the anti-slip part 925 of the first plate-like part 905 of the base 2, the friction between the article 3 and the hot melt adhesive of the anti-slip part 925 is large, and the tension of the film 24 Therefore, it is possible to suppress the article 3 from being displaced and falling from the first plate-shaped portion 905. Further, even when the article 3 is displaced from the anti-slip portion 925, the article 3 abuts against the side surface of the cause piece 945 and the cause piece 949 of the cause portion 940. Therefore, the article 3 can be prevented from falling from the first plate-like portion 905. In addition, since the raising direction of the raising piece 945 and the raising piece 949 is a direction orthogonal to the conveyance direction of the base 2, the piece 945 and the raising piece 949 caused by the pressing force of the article 3 are pushed back to the first plate-like portion 905. Can be prevented.

  The CPU 201 controls the driving unit 212 to continuously drive the second motor 222 and continuously rotate the belt 51 in the forward direction. The pedestal 2 is continuously conveyed to the downstream receiving table 12. Since torque is applied to the film roll 22 by a clutch spring and tension is applied to the film 24, the first plate of the pedestal 2 to which the tip of the film 24 is adhered as the film 2 is conveyed to the downstream side. An upward force acts on the downstream side of the portion 905. Similarly, an upward force also acts on the cradle 12 that supports the belt 51 provided with the transport unit 60 that transports the base 2 via the pulleys 52 and 53. In contrast, the upstream end of the guide portion 16 contacts the downstream end of the side plate portions 111 and 112, thereby preventing the base 2 and the cradle 12 from being lifted upward.

  The base 2 is continuously conveyed to the downstream side, and the film 24 is disposed at a position covering the first plate-like portion 905 of the base 2 and the upper side of the article 3. The film 24 adheres to the upper surface of the article 3 by the torque applied to the film roll 22. An upstream end (second side 902) of the first plate-like portion 905 of the base 2 passes over the base guide roller 71. Further, the base 2 is conveyed downstream (arrow 146). The second side 902 of the first plate-like portion 905 of the base 2 crosses the intersection position 105 from the upstream side to the downstream side. The film 24 extending from the film roll 22 contacts the upstream side of the second auxiliary roller 33 and is guided slightly upstream, contacts the upstream side and the lower side, extends downstream, and extends under the first auxiliary roller 32. The first side 901 of the first plate-like portion 905 of the base 2 and the downstream side of the article 3. The guide roller 31 is disposed above the film 24 extending between the first auxiliary roller 32 and the base 2 and the article 3.

  As shown in FIG. 16, the CPU 201 starts conveying the second side 902 of the first plate-like portion 905 of the pedestal 2 to the downstream side of the intersection position 105 in S25 to the downstream side of the pedestal 2. Then, it is detected based on the number of rotations of the second motor 222. When the second side 902 of the first plate-like portion 905 of the pedestal 2 moves to the downstream side of the crossing position 105, the CPU 201 controls the driving unit 212 to stop the driving of the second motor 222, and The conveyance is stopped (S26).

  The packaging device 1 may include a position sensor in the vicinity of the intersection position 105. When the position sensor detects the second side 902 of the first plate-like portion 905 of the pedestal 2, the CPU 201 moves the second side 902 of the first plate-like portion 905 of the pedestal 2 to the downstream side of the intersection position 105. You may judge that you did.

  The CPU 201 controls the drive unit 211 to drive the first motor 221 and lower the support unit 34. The movable roller 30 supported by the support part 34 moves from the highest level to the lowest level. The guide roller 31 descends from the uppermost side to the lowermost side along the movement path 104 (S27). The guide roller 31 comes into contact with the film 24 arranged below from above, and guides the film 24 downward along the movement path 104.

  As shown in FIG. 21, the guide roller 31 descends along the movement path 104 (arrow 147) and is arranged at the lowest position. The guide roller 31 is in contact with the conveyance path 103 from below. The film 24 is disposed at a position that covers the first plate-like portion 905 of the base 2 and the upstream side of the article 3. The film 24 extends from the portion that contacts the second side 902 of the first plate-like portion 905 of the base 2 toward the guide roller 31, contacts the downstream side and the lower side of the guide roller 31, and extends upstream. It contacts the lower side of the one auxiliary roller 32 and extends further upstream, and contacts the lower side and the upstream side of the second auxiliary roller 33 to reach the film roll 22. A portion of the film 24 between a portion that contacts the lower side of the guide roller 31 and a portion that contacts the lower end of the first auxiliary roller 32 extends in a substantially horizontal direction and extends upward from the cutting portion 77. It will be in the state arranged below the upper end of. In the state where packaging device 1 is initialized (refer to S11), since cutting part 77 has moved to the left side, film 24 and blade part 771 are not in contact at this point.

  As illustrated in FIG. 16, the CPU 201 controls the driving unit 212 to drive the second motor 222 to rotate the belt 51 in the reverse direction. The transport unit 60 moves from the downstream side to the upstream side, and transports the base 2 to the upstream side along the transport path 103 (S29). The pedestal 2 is conveyed in the reverse direction (the direction from the downstream side toward the upstream side).

  As shown in FIG. 22, when the base 2 moves from the downstream side to the upstream side (arrow 148), the second side 902 of the first plate-like portion 905 of the base 2 approaches the intersection position 105 from the downstream side. The second side 902 of the first plate-like portion 905 of the base 2 crosses the intersection position 105 from the downstream side toward the upstream side. The second side 902 of the first plate-like portion 905 of the pedestal 2 passes above the heating unit 40 and moves upstream. The guide roller 31 relatively moves toward the downstream side from the second side 902 in a state of being in contact with the lower surface of the first plate-like portion 905 of the base 2 from the lower side. The film 24 is sandwiched between the lower surface of the first plate-like portion 905 of the base 2 and the guide roller 31.

  As shown in FIG. 23, the film 24 extends downstream from the portion that contacts the second side 902 of the first plate-like portion 905 of the base 2 along the lower surface of the first plate-like portion 905, and the guide roller 31. The guide roller 31 extends from the lower side to the upstream side, contacts the lower side of the first auxiliary roller 32, extends further to the upstream side, It contacts the upstream side and reaches the film roll 22.

  As shown in FIG. 16, the CPU 201 confirms that the second side 902 of the first plate-like portion 905 of the pedestal 2 has moved to the upstream side by a predetermined distance with respect to the upper position of the heating unit 40 in S29. Detection is based on the number of rotations of the second motor 222 after the start of upstream conveyance. The predetermined distance is substantially the same as the distance from the second side 902 of the first plate-like portion 905 to the second straight line 982 (see FIG. 11). When the second side 902 of the first plate-like portion 905 of the pedestal 2 moves a predetermined distance upstream from the upper position of the heating unit 40, the CPU 201 controls the driving unit 212 to drive the second motor 222. It stops, and the conveyance of the base 2 is stopped (S30).

  The film 24 extending from the guide roller 31 to the film roll 22 via the first auxiliary roller 32 and the second auxiliary roller 33 is supported by the first auxiliary roller 32 and the second auxiliary roller 33 supporting the film 24 on the lower side. The first plate-like portion 905 of the base 2 is disposed on the lower side in the vicinity of the second side 902. For this reason, even if the pedestal 2 moves upstream in S29 and S30, the film 24 does not contact the pedestal 2. As described above, the first auxiliary roller 32 and the second auxiliary roller 33 can prevent the film 24 from coming into contact with the base 2 when the base 2 is conveyed from the downstream side to the upstream side.

  In this state, the film 24 extends downstream from the second side 902 of the first plate-like portion 905 of the base 2 along the lower surface (see FIG. 23). Here, as shown in FIG. 11, the second adhesive in which a hot melt adhesive is applied between the second side 902 and the second straight line 982 in the lower surface of the first plate-like portion 905 of the base 2. The application part 972 is affixed. Therefore, a portion of the film 24 that extends downstream from the second side 902 of the first plate-like portion 905 of the pedestal 2 along the lower surface is attached to the lower surface of the first plate-like portion 905 of the pedestal 2. It will be in the state where it overlapped with the lower side of two adhesive application parts 972.

  As shown in FIG. 16, the CPU 201 controls the drive unit 214 to drive the fourth motor 224, and moves the stopper 81 of the rotation suppression unit 80 to the upstream side (S31). As shown in FIG. 24, on the upstream side of the stopper 81 of the rotation suppressing unit 80, the guide roller 31 in the lowest position is arranged. When the stopper 81 moves upstream (arrow 149), the rubber 811 (see FIG. 11) provided on the stopper 81 is close to the guide roller 31 (see FIG. 23) and is wound around the guide roller 31. The film 24 is sandwiched between the guide rollers 31. The spring 83 (see FIG. 11) of the rotation suppressing unit 80 biases the stopper 81 upstream, and the rubber 811 of the stopper 81 pushes the guide roller 31 upstream through the film 24. Accordingly, the rotation of the guide roller 31 is prohibited, and the film 24 is sandwiched between the guide roller 31 and the rubber 811 of the stopper 81.

  The CPU 201 controls the drive unit 215 to drive the fifth motor 225, and moves the cutting unit 77 from the left side to the right side along a guide rail (not shown) (S33). As shown in FIG. 23, the upper end of the blade portion 771 of the cutting portion 77 is disposed above the film 24 extending substantially horizontally between the lower side of the guide roller 31 and the lower side of the first auxiliary roller 32. For this reason, when the cutting portion 77 moves to the right side, the film 24 is cut by the blade portion 771 at a portion extending between the guide roller 31 and the first auxiliary roller 32. The cutting part 77 separates the part of the film 24 that covers the first plate-like part 905 of the base 2 and the article 3 from the part wound around the film roll 22.

  Since torque is applied to the film roll 22, tension is applied to a portion of the film 24 that extends substantially horizontally between the guide roller 31 and the first auxiliary roller 32. Further, since the first auxiliary roller 32 pushes down the film 24 extending between the guide roller 31 and the second auxiliary roller 33, a stronger tension acts on the film 24. For this reason, when the cutting part 77 moves to the right side, the film 24 can be appropriately cut without clinging to the blade part 771.

  Here, when the blade portion 771 is moved in the right direction in a state of being in contact with the film 24 to cut the film 24, a force for guiding the film 24 to the right side acts. However, the rotation of the guide roller 31 is prohibited by the stopper 81. The stopper 81 sandwiches the film 24 between the guide roller 31 and the stopper 81. For this reason, the position of the film 24 with respect to the guide roller 31 becomes fixed and does not move to the right side by the blade portion 771. For this reason, the film 24 can be appropriately cut by the blade portion 771. Even after the film 24 is cut, the guide roller 31 and the stopper 81 maintain the state where the film 24 is sandwiched. For this reason, it can prevent that the film 24 slip | deviates from the articles | goods 3 after the cutting | disconnection by the blade part 771. FIG.

  As shown in FIG. 25, after the film 24 is cut, the cut end portion of the film 24 extending from the film roll 22 hangs down below the pedestal guide roller 71.

  As shown in FIG. 16, the CPU 201 controls the drive unit 216 to drive the sixth motor 226 to swing the holding unit 78 (S35). As shown in FIG. 26, the holding portion 78 swings in the direction of the arrow 150. The holding roller 72 is disposed in the vicinity of the downstream side of the pedestal guide roller 71. 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.

  CPU201 controls actuator 213, drives third motor 223, and raises heating part 40 (S37). After the heating unit 40 is placed in the uppermost position, the CPU 201 controls the drive unit 213 to stop driving the third motor 223 and stop the heating unit 40 from rising. As shown in FIG. 26, the upper surface of the heating unit 41 (see FIG. 8) of the heating unit 40 is close to the conveyance path 103 from below with the heating unit 40 raised to the top (arrow 151). . The support part 414 sandwiches the film 24 between the base 2 and fixes the position of the heater 411 with respect to the film 24.

  Note that the second side 902 of the first plate-like portion 905 of the pedestal 2 is moved upstream by a predetermined distance from the position above the heating unit 40. In the vicinity of the second side 902 of the lower surface of the first plate-like portion 905 of the pedestal 2, the film 24 guided by the guide roller 31 is arranged along the lower surface. As shown in FIG. 11, a second adhesive application portion 972 is affixed between the second side 902 and the second straight line 982 on the lower side of the first plate-like portion 905 of the base 2. For this reason, the film 24 arranged along the lower surface of the first plate-like portion 905 of the pedestal 2 and the second adhesive application portion 972 overlap each other. Therefore, when the heating unit 40 is raised and disposed at the uppermost position, the upper surface of the heating unit 41 is in a state where the film 24 and the second adhesive application unit 972 are sandwiched between the heating unit 40 and the base 2.

  As shown in FIG. 16, the CPU 201 heats the heater 411 of the heating unit 40 (S39). The heater 411 heats the film 24 and melts the film 24. At the same time, the heater 411 heats the second adhesive application part 972 attached to the base 2 via the film 24 and melts the second adhesive application part 972. The melted film 24 and the second adhesive application part 972 are bonded. Thus, the end portion of the film 24 cut by the cutting portion 77 is bonded to the vicinity of the second side 902 of the first plate-like portion 905 of the base 2 via the second adhesive application portion 972 (S39). . The film 24 cut from the film roll 22 is in a state of covering the base 2 and the article 3.

  The CPU 201 stops the heating of the heater 411 after a predetermined time has elapsed since the heating of the heater 411 was started in S39 (S40). The CPU 201 controls the drive unit 213 to drive the third motor 223 and lower the heating unit 40 (S41, arrow 152 (see FIG. 27)). The upper surface of the heating unit 41 is separated from the conveyance path 103 (see FIG. 27). After the heating unit 40 is disposed at the lowest position, the CPU 201 controls the driving unit 213 to stop the rotation of the third motor 223.

  The CPU 201 controls the drive unit 214 to drive the fourth motor 224 to move the stopper 81 of the rotation suppression unit 80 to the downstream side (S43, arrow 153 (see FIG. 27)). The stopper 81 moves downstream, and the rubber 811 provided on the stopper 81 is separated from the guide roller 31 (see FIG. 27). The guide roller 31 is in a rotatable state.

  The CPU 201 controls the drive unit 212 to drive the second motor 222, rotates the belt 51 in the forward direction, and conveys the base 2 to the downstream side (S45). The pedestal 2 and the article 3 that have been packaged are transported downstream and placed on the cradle 12. As the belt 51 rotates in the forward direction, the transport unit 60 moves downstream. As shown in FIG. 22, when the first conveyance unit 61 fixed to the belt 51 reaches the end on the downstream side of the cradle 12, the belt 51 is wound around the pulley 521 and bent, thereby causing the first protrusion. The first direction side of the bottom surface of the portion 611 is separated from the belt 51. The 1st protrusion part 611 will be in the state extended in the diagonal direction toward the downstream and upper direction.

  The CPU 201 confirms that the first transport unit 61 has moved downstream and reached the downstream end of the cradle 12 after starting the transport of the pedestal 2 to the downstream side in S45 (see FIG. 16). It detects based on the rotation speed of the second motor 222. When the first transport unit 61 moves downstream and reaches the downstream end of the cradle 12, the CPU 201 controls the drive unit 212 to drive the second motor 222 as shown in FIG. Stop and stop the conveyance of the base 2 (S46). Since the first projecting portion 611 extends in the oblique direction toward the downstream side and upward, the first projecting portion 611 is separated from the second side 902 of the first plate-shaped portion of the base 2. Further, the distance between the upstream end portion of the first extending portion 612 and the second protruding portion 621 of the second transport portion 62 is separated. Therefore, the user can easily remove the pedestal 2 from the transport unit 60. The packaging process ends.

  In S <b> 35, the end of the film 24 cut by the cutting portion 77 is held between the pedestal guide roller 71 and the holding roller 72 by swinging the holding portion 78. Therefore, the user can continuously wrap the next pedestal 2 and the article 3 with the film 24 without pulling out the film 24 from the film cassette 21 and holding the tip between the pedestal guide roller 71 and the holding roller 72. Is possible. When the user continuously performs the packaging operation, the CPU 201 drives the second motor 222 by controlling the drive unit 212 so that the belt 51 rotates in the reverse direction after the packaging process is completed. The CPU 201 moves the transport unit 60 from the downstream side to the upstream side, and arranges the transport unit 60 on the cradle 13. At the same time, the CPU 201 brings the support part 34 and the cutting part 77 into a state immediately after initialization (S11).

  FIG. 28 shows a state in which the base 2 packaged by the packaging device 1 is accommodated in the packaging box 996. In FIG. 28, the article 3 (see FIG. 17) is omitted. The upper side, the lower side, the left side, and the right side of FIG. 28 are referred to as the upper side, the lower side, the right side, and the left side of the packaging box 996 and the base 2, respectively. The third side 903 and the fourth side 904 of the pedestal 2 are in contact with the intersecting positions of the side wall and the upper wall of the packaging box 996, respectively. The second plate-like portions 906 and 907 are slightly inclined such that the lower ends are directed inward in the left-right direction. Even in this state, the second plate-like portions 906 and 907 are substantially perpendicular to the first plate-like portion 905 when viewed along the transport direction. The front end portions of the side protrusions 936 are in contact with the left and right side walls of the packaging box 996. The tip portion of the bottom surface protruding portion 926 comes into contact with the bottom wall of the packaging box 996.

  The first plate-like portion 905 is supported by a bottom projection 926 that projects downward from both left and right ends. The first plate-like portion 905 is spaced upward from the bottom wall of the packaging box 996. A side protrusion 936 that protrudes to the right is interposed between the right side wall of the packaging box 996 and the second plate-shaped part 907, and a side protrusion 936 that protrudes to the left is on the left side of the packaging box 996. Between the side wall and the second plate-like portion 906. A space is provided between the second plate-like portions 906 and 907 and the packaging box 996. The article 3 is packaged by the film 24 while being placed on the first plate-like portion 905 of the base 2. The first plate-like portion 905 is stably fixed in the packaging box 996 while being separated from the packaging box 996. Therefore, the impact from the outside on the packaging box 996 is not easily transmitted to the article 3 fixed on the first plate-like portion 905. In this way, the article 3 is protected.

  Further, even when a load is applied in a direction perpendicular to the side wall, top wall, or bottom wall of the packaging box 9, the load is a plurality of crests in each side protrusion 936 or each bottom protrusion 926. 974 (see FIG. 5) and trough 975 (see FIG. 5). Accordingly, the load resistance can be improved even when the pedestal 2 is accommodated in the packing box 9.

  In addition, the extending direction of each second bottom surface cut 922 and each second side surface cut 932 is parallel to the extending direction of the bent portions 911 and 912 and is orthogonal to the extending direction of the plurality of peak portions 974 and trough portions 975. (See FIG. 6). When the pedestal 2 is accommodated in the packaging box 9, each bottom surface protrusion 926 is substantially perpendicular to the bottom wall of the packaging box 9, and each side surface protrusion 936 is substantially perpendicular to the side wall of the packaging box 9. In some cases, a load is applied in a direction perpendicular to the side wall, the upper wall, or the bottom wall of the packing box 9, and the load is transmitted to the front end portions of the side surface protrusion portions 936 or the bottom surface protrusion portions 926. Even in this case, the load tends to be directed in the direction in which the plurality of peaks 974 and valleys 975 inside each side protrusion 936 or each bottom protrusion 926 are compressed. Therefore, the load is less likely to be directed in the direction in which the plurality of peak portions 974 and valley portions 975 are bent, and the plurality of peak portions 974 and valley portions 975 are more difficult to deform. Therefore, even if the base 2 is accommodated in the packing box 9, it can further improve load resistance.

  As described above, when the pedestal 2 is accommodated in the packaging box 996 while being bent by the pair of bent portions 911 and 912, the base 2 is first removed from the peripheral wall of the packaging box 996 by the bottom surface protruding portion 926 and the side surface protruding portion 936. The plate-like portion 905 can be separated. Therefore, it is possible to suppress the impact applied to the packaging box 996 from being transmitted to the article 3 in a state where the base 2 on which the article 3 is placed is accommodated in the packaging box 996. The pedestal 2 can protect the article 3 from an impact applied to the packing box 996.

  Further, by folding the plate-like portion 90 with the pair of bent portions 911 and 912, the base 2 is difficult to bend in the transport direction. Therefore, when the film 24 is put on the pedestal 2 in the direction in which the tension is applied in the conveyance direction, and the pedestal 2 and the article 3 are packaged with the film 24, the pedestal 2 can be prevented from being bent by the tension of the film 24.

  The pair of first bottom surface cuts 921 and the pair of first side surface cuts 931 extend from the pair of bent portions 911 and 912, respectively. For this reason, when a user applies a force to the plate-like portion 90 in order to bend the plate-like portion 90, the force concentrates on the pair of bent portions 911 and 912. For this reason, the user can bend the plate-shaped part 90 easily, without applying strong force. Further, the user can appropriately bend the plate-like portion 90 along the pair of bent portions 911 and 912.

  In a state where the plate-like portion 90 is bent by the pair of bent portions 911 and 912, the left and right end portions of the side protrusions 936 extending along the same plane as the first plate-like portion 905 are in contact with the inner side wall of the packaging box 996. Can be made. Thereby, when the base 2 is accommodated in the packaging box 996, the horizontal position of the plate-like portion 90 relative to the packaging box 996 can be stabilized. Further, the third side 903 and the fourth side 904 can be brought into contact with the inside of the portion where the upper wall and the side wall of the packaging box 996 intersect in a state where the plate-like portion 90 is bent by the pair of bent portions 911 and 912. . Further, the end of the bottom projection 926 extending along the second plate-like portions 906 and 907 can be brought into contact with the bottom wall inside the packaging box 996. Thereby, when the base 2 is accommodated in the packaging box 996, the position of the plate-shaped part 90 in the vertical direction with respect to the packaging box 996 can be stabilized. As a result, even when the packing box 996 moves, the base 2 follows the movement of the packing box 996, and therefore the base 2 moves within the packing box 996 and collides with the top wall, the bottom wall, and the side wall, 2 and the article 3 fixed to the base 2 can be prevented from being damaged.

  A plurality of holes 927 are formed in the plate-like portion 90 in a state where the plate-like portion 90 is bent by the pair of bent portions 911 and 912. When the pedestal 2 is transported, one of the pair of first bottom surface cuts 921 and the extending direction of the pair of first side surface cuts 931 are orthogonal to the transport direction. Accordingly, when the second protrusion 621 of the second transport unit 62 is inserted into the hole 927 and the second transport unit 62 is moved, the second transport unit 62 is difficult to be removed from the hole 927 of the base 2. Therefore, the packaging device 1 can appropriately transport the pedestal 2.

  When the pedestal 2 is bent by the pair of bent portions 911 and 912, the user holds the third side 903 and the fourth side 904 of the plate-like portion 90 by hand and applies force inward in the left-right direction. Here, the bottom surface portion 92 and the side surface portion 93 are provided symmetrically with respect to the straight line 96. For this reason, the force applied by the user to the plate-like portion 90 is equally applied to each of the pair of bent portions 911 and 912. Therefore, the user can easily bend the base 2 along the pair of bent portions 911 and 912.

  The extending direction of the bent portions 911 and 912 intersects the extending direction of the plurality of peak portions 974 and valley portions 975. A plurality of peak portions 974 and trough portions 975 are bent along with the bending at the bent portions 911 and 912 of the plate-like portion 90. The second plate-like portions 906 and 907 are not easily tilted because the standing state is maintained by the plurality of peak portions 974 and valley portions 975. Even when a load is applied in the left-right direction, the load is distributed by the second plate-like portions 906 and 907. Further, even when a load is applied to the pedestal 2 in the vertical direction or the horizontal direction, the load is distributed by the plurality of peak portions 974 and valley portions 975. Therefore, the base 2 is not easily deformed. Further, the first plate-like portion 905 and the second plate-like portions 906 and 907 are connected to each other along the transport direction and improve the load resistance in the transport direction. Therefore, the base 2 can improve load resistance. Even when a load is applied in a direction perpendicular to the side wall, top wall, or bottom wall of the packaging box 9 in which the base 2 is accommodated, the load is distributed by the plurality of peak portions 974 and valley portions 975. The Therefore, even if the base 2 is accommodated in the packing box 9, it can improve load resistance.

  In addition, when the plate-like portion 90 is bent with the bent portions 911 and 912 as a boundary, the plurality of peak portions 974 and valley portions 975 extend from the base end side to the tip end side of each bottom surface protruding portion 926 and each side surface protruding portion 936. It is extended. Even when a load is applied to the side wall, the top wall, or the bottom wall of the packaging box 9 in which the pedestal 2 is accommodated, the load is distributed to the plurality of peak portions 974 peak portions and valley portions 975. Each bottom projection 926 and each side projection 936 are not easily deformed. Therefore, even when the pedestal 2 is accommodated in the packing box 9, the load resistance can be further improved.

  The extending directions of the bent portions 911 and 912, the second side surface cut 932, and the second bottom surface cut 922 are orthogonal to the extending directions of the plurality of peak portions 974 peak portions and valley portions 975. Further, the bottom protrusion 926 is substantially perpendicular to the first plate-like portion 905. Even when a load is applied to the pedestal 2 in the vertical direction or the horizontal direction, the load acting on the inside of the pedestal 2 from the front end portions of the side surface protruding portion 936 and the bottom surface protruding portion 926 is a plurality of peak portions 974 and It is easy to face the direction in which the portion 975 is compressed in the extending direction. Therefore, the base 2 can further improve load resistance. Even when a load is applied in the vertical direction to the side wall, top wall, or bottom wall of the packing box 9 in which the base 2 is accommodated, the load compresses a plurality of peak portions 974 peaks and 975 valleys. It is easy to face in the direction to make. Therefore, even if the base 2 is accommodated in the packing box 9, the load resistance can be further improved.

  In the above embodiment, since the first adhesive application part 971 and the second adhesive application part 972 to which the hot melt adhesive is applied are provided, the film 24 can be easily attached to the base 2 as compared with the case where a tape is used. A portion to be fixed to is formed. Costs are also reduced. Moreover, since the anti-slip | skid part 925 is also formed with a hot-melt-adhesive agent, compared with the case where a tape is used, a non-slip | skid part can be formed easily. Costs are also reduced. The first adhesive application part 971, the second adhesive application part 972, and the anti-slip part 925 are all applied with hot melt adhesive. Therefore, no problem occurs even if the anti-slip portion 925 is covered with the hot melt adhesive in the step of applying the hot melt adhesive to the first adhesive applying portion 971 and the second adhesive applying portion 972. . The reverse case does not cause any problems. The left-right direction corresponds to the “first direction” and the “constant direction” of the present invention.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, the inclination angle of the inclined portion 918 and the starting position of the inclination may be appropriately determined according to the structure of the packaging device 1. Further, it is not always necessary to provide four inclined portions 918, and only two downstream portions may be provided. Further, the numbers and positions of the mark 951 to the mark 956, the mark 957 to the mark 959, and the mark 961 to the mark 963 are not limited to the above embodiment, and may be appropriately determined according to the structure of the packaging device 1 and the size of the base 2. That's fine. Further, the shape of the anti-slip portion 925 is not limited to a quadrangle, and may be various shapes such as a circle.

  Further, the bent portions 911 and 912 may be cut. The bent portions 911 and 912 may be weaker than other portions by being subjected to processing such as bending once. The bent portions 911 and 912 may be provided with perforations.

  The positions of the bent portions 911 and 912 in the left-right direction can be changed. For example, the base 2 may include a plurality of pairs of bent portions. The user may be able to select a bent portion to be actually bent according to the size of the packaging box 996. The extending direction of the bent portions 911 and 912 is not limited to the direction parallel to the transport direction, and may be inclined with respect to the transport direction. Even in this case, the extending direction of the bent portions 911 and 912 intersects with the extending direction of each mountain portion 974 and each valley portion 975.

  The shapes of the pair of first bottom surface cuts 921 and second bottom surface cuts 922 of the bottom surface portion 92 are not limited to linear shapes. For example, the shape of the pair of first bottom surface cut 921 and second bottom surface cut 922 may be adjusted so that the shape of the hole 927 to be formed is substantially the same as the shape of the second protrusion 621 in plan view. If it does in this way, since the 2nd protrusion part 621 of the 2nd conveyance part 62 will fit in the state closely_contact | adhered to the hole 927, it becomes possible to push the base 2 appropriately.

  The base 2 may include four or more (for example, eight) bottom surface portions 92. The pedestal 2 may include two or more side surfaces 93 (for example, four).
