  In the packaging apparatus, the pedestal conveyed toward the upstream side and the film in contact with the article may exert an upward force on the pedestal and the article. When the pedestal and the article are lifted upward by this force, there is a problem that the packaging device may not be able to properly package the pedestal and the article.

  An object of the present invention is to provide a packaging device capable of appropriately packaging an article.

  The packaging apparatus according to the first aspect of the present invention is a packaging apparatus that wraps a pedestal and an article placed on the pedestal with a film, and a transport mechanism that transports the pedestal on which the article is placed. And a pair of support members including one side support member and the other side support member that are separated from each other in a crossing direction that intersects the transport direction of the pedestal, and a portion that is provided on the one side support member and extends in the transport direction It is a part provided in one side 1st extension part and the other side support member, and was supported between a pair of 1st extension parts including the other side 1st extension part extended along the conveyance direction. The guide mechanism is moved such that the guide member moves along a movement path extending in a vertical direction with respect to a conveyance path through which the pedestal conveyed by the conveyance mechanism passes and a guidance mechanism having a guidance member. A moving mechanism; A first transport unit that controls the transport mechanism to transport the pedestal from an upstream side to a downstream side in the transport direction with respect to an intersecting position that is a position where the transport path and the moving path intersect; and When the pedestal is transported by the transport means and the upstream end of the pedestal moves to the downstream side of the crossing position, the guide member and the pair of first extending portions are disposed on the transport path. A moving means for controlling the moving mechanism to move the guide mechanism from the upper side to the lower side of the transport path until the guide mechanism is arranged on the lower side; In a state where the extended portion is moved to the lower side of the conveyance path, the downstream end portion is disposed at least on the upper side of the pair of first extended portions across the conveyance path. More downstream than the guide member And at least one second extending portion that is placed, and second conveying means for controlling the conveying mechanism to convey the pedestal to the upstream side after moving the guide member by the moving means, I have.

  The packaging device causes the film to adhere to at least a part of the downstream side of the article by conveying the pedestal on which the article is placed from the upstream side to the downstream side with respect to the intersection position. Next, the packaging device disposes the film on the upstream side of the pedestal and the article by moving the guide member from the upper side to the lower side of the conveyance path along the movement path. Next, the packaging apparatus brings the film into close contact with at least a part of the upstream side of the article by conveying the base and the article to the upstream side.

  In the above, in a state where the guide member has moved to the lower side of the transport path, the guide member and the pair of first extending portions are disposed on the lower side of the transport path, and at least one second extended portion is disposed on the transport path. It is arranged on the upper side. For this reason, when the packaging device transports the pedestal and the article to the upstream side, at least one of the pedestal and the article is arranged downstream between the pair of first extending portions and at least one second extending portion. You can enter from. In this case, the at least one second extending portion can suppress at least one of the base and the article from lifting upward. Therefore, the packaging device can appropriately move the pedestal and the article along the conveyance path to the upstream side, so that at least a part of the pedestal and the article can be appropriately packaged by the film.

  In the first aspect, the pair of support members are held in a state where the at least one second extending portion, the pair of first extending portions, and the at least one second extending portion are separated in the vertical direction. And at least one holding part. In this case, the pair of first extending portions and the at least one second extending portion are integrally formed as a pair of support members. In this case, the gap between the pair of first extending portions and at least the second extending portion can be kept constant. Therefore, when the packaging device transports the pedestal and the article to the upstream side, the packaging device appropriately places at least one of the pedestal and the article in the gap between the pair of first extending portions and at least one second extending portion. Since it can be made to enter, it can suppress appropriately raising at least any one of a base and an article | item.

  In the first aspect, the at least one second extending portion includes one side second extending portion provided on the one side supporting member, and the other side second extending portion provided on the other side supporting member. A pair of second extending portions including a portion, wherein the at least one holding portion is provided on the one side support member and holds the one side first extending portion and the one side second extending portion. A pair of holding parts including a one side holding part and the other side holding part that is provided on the other side supporting member and holds the one side first extending part and the one side second extending part may be provided. Good. In this case, the packaging device can suppress the pedestal and the article to be conveyed upstream from coming into contact with the second extending portion.

  In the first aspect, the guide mechanism may further include an erection member extending between the pair of support members. In this case, the erection member can press at least one of the pedestal and the article conveyed to the upstream side from the upper side over the entire region in the crossing direction. In this case, the installation member can further appropriately suppress at least one of the base and the article from lifting upward.

  1st aspect WHEREIN: The said conveyance mechanism is provided with the conveyance part which hold | maintains the said base from the upper side, The said packaging apparatus is provided with the one side board member provided in the one side of the said cross direction rather than the said conveyance path | route, and the other side A pair of side plate members including the other side plate member provided on the one side, the pair of side plate members projecting from the other side surface of the one side plate member to the other side, and the other side plate It is a pair of members including the other side protruding member protruding to the one side from the one side surface of the member, and the lower end is arranged at the same height as the upper end of the conveying unit or above the upper end of the conveying unit A pair of protruding members formed, and at least a part of a lower end of the at least one second extending portion may be disposed below a lower end of the pair of protruding members.

  The packaging device conveys the pedestal from the upper side by the conveying unit. The pair of projecting members suppress at least one of the base and the article from being lifted upward inside the pair of side plate members. Here, the lower ends of the pair of projecting members need to be disposed at the same height as the upper side of the transport unit or above the upper end of the transport unit. The reason is to secure a region through which the transport unit passes when the transport unit transports the pedestal and the article. On the other hand, the lower end of at least one second extending portion can be disposed below the lower ends of the pair of projecting members. Therefore, the packaging device can reduce the gap between at least one second extending portion and at least one of the base and the article. In this case, the at least one second extending portion can more appropriately suppress at least one of the base and the article from lifting upward.

  1st aspect WHEREIN: The said conveyance mechanism is provided with the conveyance part which hold | maintains the said base from the upper side, and the said packaging apparatus is provided in the one side plate member and other side which were provided in the said crossing direction rather than the said conveyance path | route. A pair of side plate members including the other side plate member, wherein the pair of side plate members projects from the other side surface of the one side plate member to the other side and the one of the other side plate members. A pair of members including a projecting member on the other side projecting from the side surface to the one side, the pair of projecting members capable of contacting the transport unit from above when transporting the pedestal by the transport mechanism, The lower end of the member may be disposed above the lower end of the pair of protruding members. The packaging device conveys the pedestal from the upper side by the conveying unit. The pair of projecting members suppress at least one of the base and the article from being lifted upward inside the pair of side plate members. Here, the lower end of the erection member is disposed above the lower ends of the pair of projecting members. For this reason, a packaging apparatus can suppress that a film contacts a construction member, when conveying a base and an article | item upstream.

  In the first aspect, the downstream side and the lower side of the at least one second extending portion are lower than the lower ends of the pair of projecting members among the downstream end portions of the at least one second extending portion. You may incline along the straight line which connects between the 1st position of an upper side, and the 2nd position of the lower edge part of the said at least 1 2nd extension part. In this case, the packaging device can widen the gap between the at least one second extending portion and the pair of first extending portions toward the downstream side. Therefore, when the pedestal and the article are transported to the upstream side, the at least one second extending part is arranged such that at least one of the pedestal and the article is paired with the pair of first extending parts and the at least one second extending part. It is possible to properly enter between.

  1st aspect WHEREIN: The said packaging apparatus is provided with the sensor which detects the said upstream edge part of the said base, The said downstream edge part of the said at least 1 2nd extension part is the said sensor of the said base. You may arrange | position above the detection position which can detect the said edge part of the upstream. In this case, when the upstream end of the pedestal moves downstream from the detection position, the packaging device can reverse the conveyance direction of the pedestal and the article and convey the pedestal and the article upstream. Here, the at least one second extending portion extends to the detection position. Therefore, at least one second extending portion can suppress the at least one of the pedestal and the article from being lifted upward immediately after the conveyance of the pedestal and the article to the upstream side is started.

  The packaging device according to the second aspect of the present invention is a packaging device for packaging a pedestal and an article placed on the pedestal with a film, and a transport mechanism for transporting the pedestal on which the article is placed. A pair of support members including one side support member and the other side support member that are spaced apart in a crossing direction that intersects the transport direction of the pedestal, and a member that is supported between the pair of support members, A guide mechanism having a guide member provided with one tooth, and the guide member moves along a moving path extending in a vertical direction with respect to a transport path through which the base transported by the transport mechanism passes. A member having a first moving mechanism for moving the guide mechanism, and a second tooth engageable with the first tooth, a first position spaced apart from the guide member, and the first position close to the guide member 2 teeth mesh with the 1st tooth And suppression member movable to a second position that has, and a, a second moving mechanism capable of moving between the first position and the second position the restraining member.

  According to the second aspect, the packaging device meshes the first teeth of the guide member and the second teeth of the suppressing member in a state where the film is guided to the vicinity of the article by the guide member. Thereby, the packaging device can appropriately suppress the movement of the film.

  In the second aspect, the guide member may include a plurality of divided guide portions that are a plurality of portions arranged in the intersecting direction and are rotatable about axes extending in the intersecting direction as fulcrums. In this case, the packaging device can easily mesh the second teeth of the restraining member with the first teeth of the guiding member when the restraining member is moved from the first position to the second position.

  2nd aspect WHEREIN: The 1st conveyance which controls the said conveyance mechanism in order to convey the said base from the upstream of the said conveyance direction to the downstream with respect to the crossing position which is a position where the said conveyance path | route and the said movement path | route cross | intersect And the first conveying means convey the pedestal, and when the upstream end of the pedestal moves to the downstream side of the intersection position, the guide member is located below the conveying path. The first moving means for controlling the first moving mechanism to move the guiding mechanism from the upper side to the lower side of the transport path until the guiding member is arranged, and the guiding member is moved by the first moving means. Then, the second conveying means for controlling the conveying mechanism to convey the pedestal to the upstream side, and the second conveying means convey the pedestal to the upstream side, and then the restraining member is moved to the first side. Front from 1 position A second moving means for controlling said second moving mechanism for moving the second position, may be provided. In this case, after the pedestal moves to the upstream side, tension acts on the film and the film tends to move relative to the guide member. In contrast, the packaging device moves the suppression member from the first position to the second position after the pedestal has moved upstream. Thereby, the packaging apparatus can suppress that a film moves with respect to a guide member, after a base moves to an upstream side.

  A packaging device according to a third aspect of the present invention is a packaging device for packaging a pedestal and an article placed on the pedestal with a film, and a transport mechanism for transporting the pedestal on which the article is placed. And a member having a heater for heating the film, wherein the heater is spaced downward with respect to a transport path through which the pedestal transported by the transport mechanism passes, and the heater in the transport path A heating mechanism that can move to a second position adjacent to the sensor, a sensor for detecting the pedestal, a moving means for moving the heating mechanism from the first position to the second position, and the sensor configured to move the pedestal to the second position. When the determination means determines that the sensor has detected the pedestal, the front of the heating mechanism in the state moved to the second position by the movement means. And a heating means for heating the heater.

  According to the third aspect, when the pedestal is detected by the sensor, the packaging device heats the heater while the heater is in contact with the conveyance path. For this reason, the packaging apparatus can suppress that the temperature of a heater rises too much by suppressing heating a heater in the state without a base.

  In the third aspect, the sensor includes a lower element that is one of a light emitting element and a light receiving element provided below the transport path, and the light emitting element and the light receiving element provided above the transport path. An upper element that is the other, and the packaging device includes the heater of the heating mechanism disposed at the first position, a third position that covers the lower element, and the second position. The heater of the heating mechanism arranged at a position and a lid member movable to a fourth position that does not cover the upper side of the lower element may be further provided. In this case, the cover member can prevent the user from touching the heater by covering the upper portion of the heater at the third position. Further, the lid member covers the upper side of the lower element at the third position, thereby preventing dust or the like from adhering to the lower element. For this reason, the packaging apparatus can suppress that the detection accuracy of the base by a sensor falls. Further, the lid member does not cover the upper side of the lower element at the fourth position, so that the light emitted from the light emitting element can be appropriately received by the light receiving element. For this reason, the packaging apparatus can detect a base appropriately with a sensor.

  In the third aspect, a pair of support members including one side support member and the other side support member that are separated in a crossing direction that intersects the transport direction of the pedestal, a guide member supported between the pair of support members, and The guide member moves along a guide mechanism provided between the pair of support members and provided on the upper side of the guide member, and a moving path extending in the vertical direction with respect to the transport path. And a moving mechanism that moves the guide mechanism, wherein the erection member is capable of transmitting light to a portion that intersects a virtual straight line connecting the lower element and the upper element. May be provided. In this case, the packaging device can guide the film in the vicinity of the base and the article by the guide mechanism. Further, by providing the transmissive portion on the erection member, it is possible to suppress the light emitted from the light emitting element from being shielded by the erection member. For this reason, the packaging device can more appropriately detect the pedestal by the sensor.

  In the third aspect, the lower element may be provided on the upstream side in the transport direction with respect to the heating mechanism. In this case, whether or not the pedestal that moves from the downstream side to the upstream side with respect to the heating mechanism is above the heating mechanism can be appropriately determined by the sensor.

  In the third aspect, the lower element may be the light emitting element, and the upper element may be the light receiving element. In this case, it becomes difficult for disturbance light to enter the light receiving element. For this reason, the light emitted from the light emitting element can be detected with high accuracy by the light receiving element. Therefore, the packaging device can appropriately detect the pedestal with the sensor.

  In the third aspect, after the heating mechanism is moved to the second position by the moving means, the light emitting means for causing the light emitting element to emit light is provided, and the determination means is light emitted from the light emitting element by the light emitting means. May not be received by the light receiving element, it may be determined that the pedestal has been detected. In this case, the packaging device can detect the presence or absence of the pedestal immediately before heating the heater. Therefore, the packaging device can more appropriately suppress heating of the heater without the pedestal.

The cam 83 rotates according to the rotation of the motor 224. The cam 83 comes into contact with the protruding portion 84A protruding upward from the left and right center of the plate-like member 84 from the upstream side. When the motor 224 rotates the cam 83, the plate member 84 moves in the transport direction. As the plate member 84 moves in the transport direction, the pair of support bars 82 and the stopper 81 also move in the transport direction.

  14 and 15 show a state after the guide mechanism 39 is disposed at the lowest position and the stopper 81 has moved upstream. The stopper 81 is disposed at a position where it can come into contact with the guide roller 30 supported by the pair of first extending portions 34B (341B, 342B) from the downstream side. The first teeth 30A of the guide roller 30 and the second teeth 81A of the stopper 81 mesh with each other. The rotation of the guide roller 30 is regulated by the stopper 81. On the other hand, FIG. 13 shows a state after the stopper 81 has moved downstream. In this case, even when the guide mechanism 39 is disposed at the lowest position, the stopper 81 is separated from the guide roller 30 on the downstream side.

<Packaging processing>
The packaging process (see FIG. 19) executed by the CPU 201 of the packaging device 1 will be described with reference to FIGS. It is assumed that the film roll 22 (see FIG. 5) is attached to the attachment members 141 and 142 (see FIG. 4) before the packaging device 1 is turned on. When the packaging apparatus 1 is powered on, the CPU 201 starts the packaging process by reading and executing the program stored in the flash ROM 202. 20 to 27 show sectional views taken along the line AA in FIG.

  As shown in FIG. 19, the CPU 201 initializes the state of the packaging device 1 (S1). Specifically, it is as follows. The CPU 201 drives the motor 221 by controlling the drive unit 211 to raise the guide mechanism 39 and arrange it at the uppermost position. The guide rollers 30 to 33 supported by the pair of support members 34 are arranged at the uppermost position (see FIG. 20). The CPU 201 drives the motor 222 by controlling the drive unit 212 to rotate the belts 511 and 512 (see FIG. 20) of the transport mechanism 50. When the sensor 205 (see FIG. 18) detects the reflecting plate, the CPU 201 controls the driving unit 212 to stop driving the motor 222. As a result, the conveying unit 60 protrudes upward from the receiving surface 12A (see FIG. 3) of the cradle 12 (see FIG. 20). The packaging device 1 is in a state in which the user can set the pedestal 2 on the receiving surface 12A of the cradle 12.

  The CPU 201 controls the driving unit 213 to drive the motor 223, and lowers the heating mechanism 86 to be arranged at the lowest position. Each heater 861A of the five heating units 861 is separated downward from the conveyance path 103 (see FIG. 20). The lid member 87 covers the top of the five heating units 861. The CPU 201 controls the drive unit 214 to drive the motor 224 and move the stopper 81 downstream (see FIG. 20). The CPU 201 controls the driving unit 215 to drive the motor 225 and move the cutting unit 77 to the left side. The CPU 201 controls the driving unit 216 to drive the motor 226 to swing the pair of holding members 78. The holding roller 72 is in a state of being separated downward with respect to the base guide roller 71. CPU201 controls light emitting element 67B of sensor 67, and stops light emission.

  The user pulls the film 24 downward from the film roll 22 and arranges it on the upstream side of the guide roller 33. The user further pulls out the film 24 and places the leading end of the film 24 below the transport path 103 (see FIG. 20) and downstream of the pedestal guide roller 71 (see FIG. 20). The user places the pedestal 2 on the cradle 12 (see FIG. 20). The pedestal 2 is positioned by the transport unit 60. The side 901 of the first plate-like portion 905 of the base 2 is disposed on the downstream side, and the side 902 is disposed on the upstream side. The article 3 is placed on the first plate-like portion 905 of the base 2 (see FIG. 20).

  The user performs an input operation for notifying the packaging apparatus 1 that preparation has been completed via the operation unit 206. The CPU 201 controls the driving unit 216 to drive the motor 226 to swing the pair of holding members 78. The holding roller 72 is close to the downstream side of the pedestal guide roller 71 (see FIG. 20). The leading end of the film 24 drawn out from the film roll 22 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. The film 24 extends in the vertical direction between the upstream side of the guide roller 33 and a portion sandwiched between the pedestal guide roller 71 and the holding roller 72.

  The CPU 201 determines whether a packaging start instruction has been input (S5). CPU201 returns a process to S5, when the packaging start instruction | indication is not input (S5: NO). When the user inputs a packaging start instruction via the operation unit 206, the CPU 201 determines that a packaging start instruction has been input (S5: YES). The CPU 201 drives the solenoid 16C to move the coupling gear 652 (see FIG. 5) to the second position, and controls the drive unit 217 to rotate the motor 227 (S7). The film 24 is forcibly fed from the film roll 22 by rollers 654A and 654B (see FIG. 5). The film 24 is loosened.

  The CPU 201 controls the drive unit 212. The CPU 201 rotates the motor 222 in the forward direction. The belts 511 and 512 rotate in the forward direction (the direction of the arrow 181 in FIG. 20). The transport unit 60 transports the base 2 from the upstream side to the downstream side along the transport path 103 (S9). 62 A of 1st conveyance parts approach from the upstream by the clearance gap below the protrusion member 15B. The upper end of the first transport unit 62A moves downstream while contacting the lower end of the protruding member 15B from below.

  The downstream end (side 901) of the first plate-like portion 905 of the base 2 contacts the film 24, and then passes over the holding roller 72 (arrow 182 in FIG. 21). The side 901 of the first plate-like portion 905 of the base 2 pushes the film 24 to the downstream side. The side 901 of the first plate-like portion 905 of the base 2 approaches the movement path 104 from the upstream side and passes above the five heating units 861 (see FIG. 21). 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 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 specifies the number of rotations of the motor 222 after starting the conveyance of the pedestal 2 according to the pulse signal output from the encoder 232 after starting the conveyance to the downstream side of the pedestal 2 by the process of S9. To do. The CPU 201 determines whether or not the 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 five heating units 861 based on the identified number of rotations of the motor 222. Judgment. When the CPU 201 determines that the side 901 of the first plate-like portion 905 of the pedestal 2 has moved a predetermined distance downstream from the upper position of the five heating units 861, the CPU 201 controls the driving portion 212 to control the motor 222. The driving is stopped, and the conveyance to the downstream side of the base 2 is stopped (S11).

  CPU201 controls actuator 213, drives motor 223, and raises heating mechanism 86 (S13). The lid member 87 is opened. After the heating mechanism 86 is placed in the uppermost position, the CPU 201 controls the drive unit 213 to stop driving the motor 223 and stop the heating mechanism 86 from rising. As shown in FIG. 21, when the heating mechanism 86 is raised to the top (arrow 183), the upper side of each of the five heating units 861 is close to the conveyance path 103 from below and slightly above the conveyance path 103. Will be placed in the state. The side 901 of the first plate-like portion 905 of the pedestal 2 has moved a predetermined distance downstream from the upper position of the heating mechanism 86, and the film 24 is placed on the lower surface of the first plate-like portion 905 of the pedestal 2. Wrap around. Accordingly, the film 24 is sandwiched between the upper side of the five heating units 861 and the lower surface of the first plate-like portion 905 of the pedestal 2 with the heating mechanism 86 disposed at the top.

  As shown in FIG. 19, the CPU 201 heats the heater 861A (S15). The heater 861A heats and melts the tip of the film 24. The front end of the melted film 24 is adhered to the vicinity of the side 901 in the lower surface of the first plate-like portion 905 of the base 2 (S15). The CPU 201 stops the heating of the heater 861A after a predetermined time has elapsed since the heating of the heater 861A was started. CPU201 controls actuator 213, drives motor 223, and lowers heating mechanism 86 (S19, arrow 184 (refer to Drawing 22)). The upper sides of the five heating units 861 are separated from the conveyance path 103. The lid member 87 is closed. After the heating mechanism 86 is disposed at the lowest position, the CPU 201 controls the drive unit 213 to stop driving the motor 223 and stop the lowering of the heating mechanism 86.

  The CPU 201 controls the drive unit 216 to drive the motor 226 to swing the pair of holding members 78 (S21). As shown in FIG. 22, the pair of holding members 78 swings in the direction of the arrow 185, so that the holding roller 72 is separated downward with respect to the pedestal guide roller 71. The pedestal guide roller 71 and the holding roller 72 release the front end of the sandwiched film 24. The leading end of the film 24 is melted by the heater 861A heated by the process of S15 (see FIG. 19) and adhered to the lower surface of the pedestal 2.

  As shown in FIG. 19, the CPU 201 drives the motor 222 by controlling the drive unit 212. The CPU 201 rotates the motor 222 in the forward direction so that the belts 511 and 512 rotate in the forward direction. The pedestal 2 is conveyed downstream (S23). 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 is moved to the downstream side as the pedestal 2 moves while being adhered to the lower surface of the pedestal 2.

  When the pedestal 2 is transported to the downstream side, the side 901 of the first plate-like portion 905 of the pedestal 2 crosses the intersection position 105 where the transport path 103 and the movement path 104 intersect from the upstream side toward the downstream side. . The pedestal 2 moves further downstream (see arrow 186, FIG. 22). The pedestal 2 passes over the sensor 68 (see FIG. 2) and contacts the sensor 68. Based on the signal output from the sensor 68, the CPU 201 determines that the pedestal 2 has been detected by the sensor 68 (S24). As the pedestal 2 moves downstream, the side 901 of the first plate-like portion 905 of the pedestal 2 and the downstream end of the article 3 come into contact with the film 24 and bend at the contact portion. The CPU 201 controls the driving unit 212 to continuously drive the motor 222 to continuously rotate the belts 511 and 512 in the forward direction. The transport unit 60 moves onto the cradle 13, and the downstream side of the base 2 is transported to the cradle 13. An upstream end (side 902) of the first plate-like portion 905 of the base 2 passes over the base guide roller 71.

  As shown in FIG. 22, the base 2 is further conveyed downstream (arrow 186). The 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 guide roller 33 and is slightly guided upstream, contacts the lower side of the guide roller 33 and extends downstream, and the first plate-like portion of the base 2. It reaches the side 901 of 905 and the downstream side of the article 3. 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 guide rollers 30 to 32 are arranged above the film 24 extending above the base 2 and the article 3.

  As shown in FIG. 19, the CPU 201 determines whether the pedestal 2 is no longer detected by the sensor 68 based on the signal output from the sensor 68 (S25). When the CPU 201 determines that the pedestal 2 is continuously detected by the sensor 68 (S25: NO), the CPU 201 returns the process to S26.

  If the side 902 of the first plate-like portion 905 of the pedestal 2 passes downstream above the sensor 68, the sensor 68 will not detect the pedestal 2. Based on the signal output from the sensor 68, the CPU 201 determines that the pedestal 2 is no longer detected by the sensor 68 (S25: YES). In this case, the side 902 of the first plate-like portion 905 of the pedestal 2 has moved downstream from the sensor 68. The CPU 201 controls the driving unit 212 to stop the driving of the motor 222 and stop the conveyance of the base 2 (S26).

  The CPU 201 controls the drive unit 211 to drive the motor 221 to move the guide mechanism 39 to the lowest position (S27). The guide roller 30 moves from the uppermost side to the lowermost side along the movement path 104. In the course of movement, the guide rollers 30 and 32 come into contact with the film 24 disposed below from the upper side, and guide the film 24 downward along the movement path 104 (see arrow 187 and FIG. 23). The film 24 is pressed against the base 2 and the article 3 from above. As shown in FIG. 23, the guide roller 31 is in a state of being in contact with the conveyance path 103 from the lower side in a state of being disposed at the lowest position. The film 24 covers the first plate-like portion 905 of the base 2 and the downstream side, the upper side, and the upstream side of the article 3.

  The CPU 201 drives the solenoid 16C to move the coupling gear 652 (see FIG. 5) to the first position, and controls the drive unit 217 to rotate the motor 227 (S29). The film 24 is wound on a film roll 22. Tension acts on the film 24. Due to the tension acting on the film 24, the film 24 adheres to the base 2 and the article 3.

  The CPU 201 rotates the motor 222 in the reverse direction so that the belts 511 and 512 rotate in the reverse direction (S31). The pedestal 2 moves from the downstream side to the upstream side (see arrow 188, FIG. 24). The side 902 of the first plate-like portion 905 of the pedestal 2 contacts the film 24 and pushes it upstream. The left and right side portions of the side 902 of the first plate-like portion 905 of the base 2 are gaps 3424 between the first extending portion 342B and the second extending portion 342C of the guide mechanism 39 (see FIGS. 16 and 17). Enter from the downstream side. The second extending portion 342C presses the first plate-like portion 905 of the pedestal 2 from the upper side and suppresses the pedestal 2 from being lifted upward.

  The side 902 of the first plate-like portion 905 of the base 2 approaches the intersection position 105 from the downstream side. The side 902 of the first plate-like portion 905 of the pedestal 2 crosses the intersection position 105 from the downstream side toward the upstream side. The guide roller 31 of the guide mechanism 39 contacts the lower surface of the pedestal 2 and moves the pedestal 2 along the gap 3424 (see FIGS. 16 and 17) between the first extending portion 342B and the second extending portion 342C. Guide upstream. The side 902 of the first plate-like portion 905 of the pedestal 2 passes above the five heating units 861 and moves upstream. 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. The film 24 goes around to the lower side of the base 2.

  In accordance with the pulse signal output from the encoder 232, the CPU 201 specifies the number of rotations of the motor 222 after starting the conveyance to the upstream side of the base 2 in S31. The CPU 201 determines whether the side 902 of the first plate-like portion 905 of the base 2 has moved upstream by a predetermined distance with respect to the upper position of the five heating units 861 based on the specified rotation speed. When the CPU 201 determines that the side 902 of the first plate-like portion 905 of the pedestal 2 has moved a predetermined distance upstream from the upper position of the five heating units 861, the CPU 201 controls the driving unit 212 to control the motor 222. The drive is stopped and the conveyance of the base 2 is stopped (S33).

  The CPU 201 controls the drive unit 214 to drive the motor 224, and moves the stopper 81 of the rotation suppression mechanism 80 to the upstream side (S35). As shown in FIG. 25, on the upstream side of the stopper 81 of the rotation suppression mechanism 80, the guide roller 30 moved to the lowest position is disposed. When the stopper 81 moves upstream (arrow 189), the plurality of second teeth 81A of the stopper 81 mesh with the plurality of first teeth 30A (see FIG. 14) of the guide roller 30. The film 24 wound around the guide roller 30 is sandwiched between the plurality of first teeth 30A and the plurality of second teeth 81A and cannot move.

  As shown in FIG. 19, the CPU 201 controls the drive unit 217 to stop the rotation of the motor 227 (S37). The winding of the film 24 onto the film roll 22 is stopped.

  CPU201 controls actuator 215, drives motor 225, and moves cutting part 77 from the left to the right along guide rail 74 (refer to Drawing 12) (S39). When the cutting portion 77 moves to the right side, the film 24 is closer to the film roll 22 than the portion sandwiched between the plurality of first teeth 30A and the plurality of second teeth 81A, and between the guide rollers 30 and 32. Is cut by the blade portion 771. The cutting part 77 cuts off the part of the film 24 that covers the first plate-like part 905 and the article 3 of the base 2 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 on the lower side of the pedestal guide roller 71. The CPU 201 controls the drive unit 216 to drive the motor 226 to swing the pair of holding members 78 (S41). As shown in FIG. 26, the pair of holding members 78 swings in the direction of the arrow 190. The holding roller 72 is disposed in the vicinity of the pedestal guide roller 71 on the downstream side. 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.

  As shown in FIG. 19, the CPU 201 controls the drive unit 213 to drive the motor 223 and raise the heating mechanism 86 (S43). As shown in FIG. 26, in the process of ascending the heating mechanism 86, the lid member 87 is opened by pushing the other end side 87B upward by the five heating units 861. After the heating mechanism 86 is placed in the uppermost position, the CPU 201 controls the drive unit 213 to stop driving the motor 223 and stop the heating mechanism 86 from rising. With the heating mechanism 86 raised to the top (arrow 191), the upper surfaces of the five heating units 861 approach the transport path 103 from below. Note that the side 902 of the first plate-like portion 905 of the pedestal 2 is moved upstream by a predetermined distance from the upper position of the five heating units 861. The film 24 is disposed in the vicinity of the side 902 on the lower surface of the first plate-like portion 905 of the base 2. Therefore, when the heating mechanism 86 is raised and disposed at the uppermost position, the film 24 is sandwiched between the upper surfaces of the five heating units 861 and the base 2.

  Note that the five heating units 861 try to lift the pedestal 2 upward in response to the heating mechanism 86 being raised and disposed at the uppermost position. On the other hand, the 2nd extension part 342C contacts the upper surface of the base 2, and suppresses that the base 2 lifts upwards. Further, when the pedestal 2 is slightly lifted upward, the installation member 35 contacts the side 902 of the first plate-like portion 905 of the pedestal 2 over the entire left and right direction. Thereby, the erection member 35 suppresses the pedestal 2 from further lifting upward.

  As shown in FIG. 19, the CPU 201 causes the light emitting element 67B of the sensor 68 to emit light (S45). The infrared light radiated from the light emitting element 67 </ b> B passes upward on the downstream side of the heating mechanism 86. Since the lid member 87 is open, infrared light is not shielded by the lid member 87. The CPU 201 determines whether the light receiving element 67A of the sensor 68 has received the infrared light emitted by the light emitting element 67B (S47). Here, when the pedestal 2 is disposed above the light emitting element 67B, the infrared light is shielded by the pedestal 2, so the light receiving element 67A does not receive the infrared light.

  When the CPU 201 determines that the light receiving element 67A is not receiving infrared light based on the signal output from the light receiving element 67A (S47: NO), the CPU 201 determines that the pedestal 2 is detected by the sensor 67. In this case, the base 2 is arranged above the five heating units 861. The CPU 201 heats the heater 861A (S49). The heater 861 </ b> A heats the end portion of the film 24 cut by the cutting portion 77 to melt the film 24. The melted film 24 is adhered to the vicinity of the side 902 of the first plate-like portion 905 of the base 2 (S49). 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 heating the heater 861A after a predetermined time has elapsed since the heating of the heater 861A was started in S49. CPU201 controls actuator 213, drives motor 223, and lowers heating mechanism 86 (S51, arrow 192 (refer to Drawing 27)). The upper surfaces of the five heating units 861 are separated from the transport path 103. The lid member 87 is closed and covers the five heating units 861 and the light emitting element 67B from above. The CPU 201 stops the light emission by the light emitting element 67B. After the heating mechanism 86 is disposed at the lowest position, the CPU 201 controls the driving unit 213 to stop the rotation of the motor 223.

  As shown in FIG. 19, the CPU 201 controls the drive unit 214 to drive the motor 224 to move the stopper 81 of the rotation suppression mechanism 80 to the downstream side (S53, arrow 193 (see FIG. 27)). The stopper 81 moves downstream, and the plurality of second teeth 81 </ b> A of the stopper 81 are separated from the plurality of first teeth 30 </ b> A of the guide roller 30. The guide roller 30 is in a rotatable state.

  The CPU 201 controls the driving unit 212 to drive the motor 222. The CPU 201 rotates the motor 222 in the forward direction so that the belts 511 and 512 rotate in the forward direction. The pedestal 2 is conveyed downstream (S55, arrow 193 (see FIG. 27)). The pedestal 2 and the article 3 that have been packaged are conveyed downstream. The CPU 201 ends the packaging process.

  On the other hand, when the infrared light radiated from the light emitting element 67B is received by the light receiving element 67A, the pedestal 2 may not be disposed above the light emitting element 67B. If the CPU 201 determines that the light receiving element 67A has received infrared light based on the signal output from the light receiving element 67A (S47: YES), it determines that the pedestal 2 is not detected by the sensor 67. In this case, the pedestal 2 may not be arranged above the five heating units 861. The CPU 201 causes the display unit 207 to display a notification screen that notifies that an error has occurred (S59). The CPU 201 ends the packaging process.

<Main effects of the above embodiment>
As described above, the packaging device 1 transports the pedestal 2 on which the article 3 is placed from the upstream side to the downstream side with respect to the intersection position 105, thereby forming a film on at least a part of the downstream side of the article 3. 24 is brought into close contact (S9, S23). Next, the packaging device 1 moves the guide roller 30 along the movement path 104 from the upper side to the lower side of the conveyance path 103, and arranges the film on the upstream side of the base 2 and the article 4 (S27). The packaging device 1 causes the film 24 to adhere to at least part of the upstream side of the article 3 by conveying the pedestal 2 and the article 3 to the upstream side (S31).

  In the above description, the guide roller 30 and the pair of first extending portions 34B are disposed below the conveying path 103 in a state where the guiding roller 30 has moved to the lower side of the conveying path 103, and the pair of second extending portions 34 </ b> C is disposed on the upper side of the conveyance path 103. Therefore, when the packaging device 1 transports the pedestal 2 and the article 3 to the upstream side, the pedestal from the downstream side to the gap 3414 between the pair of first extending portions 34B and the pair of second extending portions 34C. 2 can enter. In addition, after conveying the base 2 and the article 3 to the upstream side, the film 24 is wound up on the film roll 22 (S37). For this reason, the base 2 and the article 3 are easily lifted upward by the film 24. Further, when the five heating units 861 come into contact with the pedestal 2 from below as the heating mechanism 86 moves to the uppermost position, the pedestal 2 is easily lifted upward. On the other hand, since the pair of second extending portions 34C can press the pedestal 2 from the upper side, the pedestal 2 and the article 3 can be prevented from being lifted upward. Accordingly, the packaging device 1 can appropriately move the pedestal 2 and the article 3 to the upstream side along the conveyance path 103, so that at least a part of the pedestal 2 and the article 3 can be appropriately packaged by the film 24.

  In the above, the first extending portion 341B and the second extending portion 341C both extend downstream from the base portion 341A. That is, the first extending portion 341 </ b> B and the second extending portion 341 </ b> C are integrally formed as the support member 341. For this reason, the distance between the upper end of the 1st extension part 341B and the lower end of the 2nd extension part 341C is kept constant. Similarly, both the first extending portion 342B and the second extending portion 342C extend downstream from the base portion 342A. That is, the first extending portion 342 </ b> B and the second extending portion 342 </ b> C are integrally formed as the support member 342. For this reason, the distance between the upper end of the 1st extension part 342B and the lower end of the 2nd extension part 342C is kept constant.

  In the above case, the gap 3414 between the first extension 341B and the second extension 341C and the gap 3424 between the first extension 342B and the second extension 342C are kept constant. Is easily possible. Accordingly, the packaging device 1 can appropriately allow the pedestal 2 to enter the gaps 3414 and 3424 when the pedestal 2 and the article 3 are conveyed upstream. Therefore, the packaging device 1 can appropriately suppress the pedestal 2 and the article 3 from being lifted upward.

  In the above description, the support members 341 and 342 are spaced apart in the left-right direction, and are disposed on the left and right sides of the space sandwiched between the side plate members 111 and 112 (see FIG. 2). The support member 341 has a first extension part 341B and a second extension part 341C, and the support member 342 has a first extension part 342B and a second extension part 342C. On the other hand, the base 2 and the article 3 transported along the transport path 103 pass through the center of the space sandwiched between the side plate members 111 and 112 (see FIG. 2). For this reason, packaging device 1 can control that a pair of 2nd extension parts 34C contact pedestal 2 and article 3 which are conveyed.

  The guide mechanism 39 has a construction member 35. The erection member 35 is provided between the support members 341 and 342. The erection member 35 can press the pedestal 2 from the upper side over the entire left and right direction. In this case, the erection member 35 can further appropriately prevent the base 2 and the article 3 from lifting upward.

  The conveyance unit 60 conveys the pedestal 2 while pressing it from above by the first conveyance units 61A and 62A. The lower ends of the projecting members 14B and 15B are in contact with the first transport parts 61A and 662A when the base 2 and the article 3 are transported. Accordingly, the protruding members 14B and 15B suppress the pedestal 2 and the article 3 from being lifted upward inside the side plate members 111 and 112 when the pedestal 2 and the article 3 are conveyed. Here, the lower ends of the projecting members 14B and 15B are the same height as the passage area 108 through which the upper sides of the first transport units 61A and 62A pass, or are disposed above the upper ends of the first transport units 61A and 62A. There is a need. The reason is to secure a region through which the first transport units 61A and 62A pass when the right transport unit 61 and the left transport unit 62 transport the base 2 and the article 3.

  On the other hand, the lower ends of the pair of second extending portions 34 </ b> C can be disposed below the passage region 108. The reason is that when the transport unit 60 passes inside the side plate members 111 and 112, the guide mechanism 39 is disposed at the top, and the pair of second extending portions 34C do not hinder the movement of the transport unit 60. Because. Therefore, the packaging device 1 can further reduce the gap in the height direction between the lower end of each of the pair of second extending portions 34 </ b> C and the base 2. Therefore, the pair of second extending portions 34 </ b> C can more appropriately suppress the pedestal 2 and the article 3 from being lifted upward.

  In the process of packaging the pedestal 2 and the article 3, the film 24 and the erection member 35 are easy to contact. Specifically, when the pedestal 2 and the article 3 are transported upstream in the packaging process, the side of the first plate-like part 905 of the pedestal 2 in the film 24 is directed toward the upstream end of the article 3. A portion extending obliquely upward tends to come into contact with the erection member 35. On the other hand, in the above, the lower plate-like member 35B of the erection member 35 is disposed above the position of the lower end of the projecting members 14B and 15B, in other words, above the position of the passage region 108. In this case, when the pedestal 2 and the article 3 are conveyed to the upstream side, the packaging device 1 makes contact between the film 24 extending upward from the side 902 of the first plate-like portion 905 of the pedestal 2 and the erection member 35. It becomes difficult to do. Even when the erection member 35 is in contact with the film 24, by providing the erection member 35 above the position of the passage region 108, the force that the erection member 35 hinders the movement of the film 24 can be reduced. Further, since the downstream side of the erection member 35 is curved by the bending member 35C, the force that the erection member 35 prevents the movement of the film 24 is further reduced. In this case, it is suppressed that the erection member 35 prevents the movement of the film 24. Thereby, it can suppress that the erection member 35 prevents a packaging process.

  The second extending portion 341C includes an inclined portion 3413 at the lower end and the downstream end. The second extending portion 342C has an inclined portion 3423 at the lower end and the downstream end. The inclined portions 3413 and 3423 can widen the gaps 3414 and 3424 between the first extending portion 34B and the second extending portion 34C toward the downstream side. Therefore, when the pedestal 2 and the article 3 are transported upstream, the pedestal 2 can easily enter the gaps 3414 and 3424. As described above, the pair of second extending portions 34C includes the inclined portions 3413 and 3423, so that the pedestal 2 is appropriately placed between the pair of first extending portions 34B and the pair of second extending portions 34C. Can enter.

  When the packaging device 1 conveys the pedestal 2 and the article 3 to the downstream side, the sensor 68 detects the side 902 of the first plate-like portion 905 of the pedestal 2 (S24). When the sensor 68 no longer detects the side 902 of the first plate-like portion 905 of the base 2 (S25: YES), the packaging device 1 reverses the transport direction and transports the base 2 and the article 3 upstream ( S31). Here, the downstream ends of the pair of second extending portions 34 </ b> C extend to a position where the sensor 68 can detect the pedestal 2, that is, a position above the pedestal 2. For this reason, the pair of second extending portions 34C can press the pedestal 2 from above immediately after the conveyance direction of the pedestal 2 and the article 3 is reversed. Therefore, the pair of second extending portions 34 </ b> C can prevent the pedestal 2 and the article 3 from being lifted upward immediately after the transport of the pedestal 2 and the article 3 to the upstream side is started.

  The packaging apparatus 1 transports the base 2 and the article 3 to the upstream side (S31), and then moves the stopper 81 to the upstream side (S35). When the pedestal 2 and the article 3 are conveyed to the upstream side, the film 24 is easily moved with respect to the guide roller 30 due to the tension acting on the film 24. In contrast, the packaging device 1 can sandwich the film 24 between the guide roller 30 and the stopper 81 by moving the stopper 81 upstream. Further, even when the film 24 is easily moved by engaging the plurality of first teeth 30A of the guide roller 30 and the plurality of second teeth 81A of the stopper 81, the film 24 moves. Can be suppressed appropriately.

  The guide roller 30 has a plurality of divided rollers 301 to 304. The division rollers 301 to 304 are connected to each other with play. In this case, when the stopper 81 comes close to the guide roller 30 and any of the divided rollers 301 to 304 rotates and the plurality of second teeth 81A of the stopper 81 are engaged with the plurality of first teeth 30A, the remaining division is performed. Each of the rollers 301 to 304 rotates within a range of play. Accordingly, the plurality of first teeth 30 </ b> A of the remaining divided rollers 301 to 304 are also easily engaged with the plurality of second teeth 81 </ b> A of the stopper 81. As described above, the packaging device 1 is configured such that the guide roller 30 includes the plurality of divided rollers 301 to 304, and the stopper 81 is brought close to the guide roller 30 by connecting each other with play. The plurality of second teeth 81A can be easily meshed with the plurality of first teeth 30A.

  If it is determined that the pedestal 2 has been detected by the sensor 67 (S47: NO), the packaging device 1 heats the heater 861A in the state of being close to the transport path 103 (S49). For this reason, the packaging apparatus 1 can suppress the temperature of the heater 861A from excessively rising by suppressing the heating of the heater 861A without the pedestal 2.

  The lid member 87 is closed with the heating mechanism 86 disposed at the lowest position. The lid member 87 in the closed state covers the five heating units 861 and the light emitting element 67 </ b> B of the sensor 67. In this case, the lid member 87 can prevent the user from touching the heater 861A. Further, the lid member 87 can suppress dust and the like from adhering to the light emitting element 67B. Therefore, the packaging device 1 can suppress a decrease in detection accuracy of the base 2 by the sensor 67.

  On the other hand, the lid member 87 is opened in a state where the five heating units 861 are arranged at the uppermost position. The open lid member 87 does not cover the five heating units 861 and the light emitting element 67B of the sensor 67. Thereby, the infrared light emitted from the light emitting element 67B can be appropriately received by the light receiving element 67A. For this reason, the packaging device 1 can appropriately detect the base 2 by the sensor 67.

  The transmission part 35D provided in the erection member 35 is disposed on the detection position P connecting the light emitting element 67B and the light receiving element 67A of the sensor 67. In this case, it is possible to prevent the infrared light emitted from the light emitting element 67B from being blocked by the installation member 35 and reaching the light receiving element 67A. For this reason, the packaging device 1 can detect the pedestal more appropriately by the sensor 67. In addition, since there is no restriction on the mounting position of the erection member 35, the position of the erection member 35 can be freely adjusted.

  The sensor 67 is provided on the upstream side of the heating mechanism 86. In this case, the sensor 67 can appropriately determine whether or not the base 2 that moves from the downstream side to the upstream side with respect to the heating mechanism 86 is above the five heating units 861.

  In the sensor 67, a light emitting element 67B is provided below the transport path 103, and a light receiving element 67A is provided above. The light receiving surface of the light receiving element 67A faces downward. In this case, disturbance light is difficult to enter the light receiving surface of the light receiving element 67A. For this reason, the light emitted from the light emitting element 67B can be detected with high accuracy by the light receiving element 67A. Therefore, the packaging device 1 can appropriately detect the base 2 by the sensor 67.

  The packaging device 1 moves the heating mechanism 86 to the uppermost position to bring the five heating units 861 close to the transport path 103 (S43), and then determines whether the pedestal 2 is detected by the sensor 67 (S47). . In this case, the packaging device 1 can detect the presence or absence of the base 2 immediately before heating the heater 861A. Therefore, the packaging device 1 can further appropriately suppress the heating of the heater 861A without the pedestal 2.

<Others>
The present invention is not limited to the above embodiment, and various modifications can be made. In the above description, the pair of second extending portions 34 </ b> C of the pair of support members 34 are arranged above the left and right sides of the base 2 with the guide mechanism 39 moved to the lowest position. Thereby, the pair of second extending portions 34 </ b> C suppressed the base 2 from being lifted upward. On the other hand, when the article 3 is arranged up to the left and right sides of the pedestal 2, the pair of second extending portions 34 </ b> C may be arranged above the left and right sides of the article 3. Accordingly, the pair of second extending portions 34 </ b> C may suppress the pedestal 2 and the article 3 from being lifted upward by contacting the article 3 above.

  In the above, the pair of second extending portions 34C extends downstream from the pair of base portions 34A. On the other hand, the pair of second extending portions 34 </ b> C may be configured separately from the pair of support members 34. For example, the pair of second extending portions 34 </ b> C may be separate members attached to the carriages 349 and 350 separately from the pair of support members 34. In this case, the pair of second extending portions 34 </ b> C may move in the vertical direction in conjunction with the pair of support members 34 as the carriages 349 and 350 move. Further, when the pair of second extending portions 34C is configured separately from the pair of support members 34, the pair of second extending portions 34C may be provided so as to protrude inward from the side plate members 111 and 112. Good.

  The pair of second extending portions 34 </ b> C may extend downstream from the installation member 35. In this case, the positions where the pair of second extending portions 34C extend from the erection member 35 are not limited to the left and right sides, and may be closer to the center than the left and right sides. In this case, one or three or more second extending portions may extend downstream instead of the pair of second extending portions 34C.

  In the above, the erection member 35 may not be provided between the pair of support members 34. For example, the erection member 35 may be divided at a portion closer to the center than the left and right sides. Further, the erection member 35 may not be provided in the guide mechanism 39. The length in the vertical direction of the erection member 35 may be the same as the length in the vertical direction of the pair of second extending portions 34C. In this case, the lower plate-like member 35B of the installation member 35 may extend inward from the lower ends of the pair of second extending portions 34C.

  In the above description, the positions of the lower ends of the projecting members 14B and 15B coincided with the passage area 108 through which the upper ends of the first transport units 61A and 62A pass.
