- the edge of the film 24 cut by the cutting portion 77 is clamped by the base guide roller 71 and the holding roller 72 . Therefore, it becomes possible to package the next base 2 and the next article 3 with the film 24 .
- the guide roller 31 of the packaging device 1 moves along the first path and the second path, and packages the base 2 and the article 3 with the film 24 .
- the guide roller 31 moves along the two movement paths (the first path and the second path) and packaging is performed. Therefore, there is no need to move the guide roller 31 around the entire periphery of the base 2 and the article 3 . It is therefore possible to reduce the size of the structure that causes the guide roller 31 to move along the movement paths.
- the packaging device 1 is a compact device, it can package the article 3 having a large size with the film 24 .
- the first support portion 33 moves along the slits 121 and 122 while supporting the guide roller 31 , the first support portion 33 can move the guide roller 31 along the first path. Further, since the second support portion 51 moves along the slits 123 and 124 while supporting the guide roller 31 , the second support portion 51 can move the guide roller 31 along the second path. Since the guide roller 31 guides the film 24 while the cylindrical portion of the guide roller 31 is rotating, it is possible to reduce friction between the guide roller 31 and the film 24 to a minimum. Therefore, the packaging device 1 can inhibit excessive tension from being applied to the film 24 by the friction between the guide roller 31 and the film 24 , and it is thus possible to inhibit the film 24 from breaking. Further, the guide roller 31 is detachably provided with respect to the first support portion 33 and the second support portion 51 . Thus, the guide roller 31 can easily move between the first support portion 33 and the second support portion 51 .
- the detachment switching portion 35 of the first support portion 33 switches between a state in which the guide roller 31 is detachable from the roller support portion 34 and a state in which the guide roller 31 is not detachable from the roller support portion 34 . Therefore, when the first support portion 33 switches to the state in which the guide roller 31 is not detachable, the first support portion 33 can reliably cause the guide roller 31 to guide the film 24 . Note that, when the first support portion 33 switches to the state in which the guide roller 31 is detachable, the guide roller 31 can easily move between the first support portion 33 and the second support portion 51 .
- the switching between the state in which the guide roller 31 is detachable and the state in which the guide roller 31 is not detachable is performed by the regulation portion 151 regulating the movement of the detachment switching portion 35 . Therefore, by adjusting the position in which the regulation portion 151 is provided, it is possible to easily switch between the state in which the guide roller 31 is detachable and the state in which the guide roller 31 is not detachable, at an appropriate timing.
- the first support portion 33 moves the auxiliary roller 32 in the up-down direction, in addition to the guide roller 31 .
- the auxiliary roller 32 In a state in which the base 2 is on the upstream side with respect to the first path, the auxiliary roller 32 is located above the conveyance surface. After the base 2 has moved to the downstream side with respect to the first path, the auxiliary roller 32 is located above the base guide roller 71 .
- the packaging device 1 can therefore effectively inhibit the auxiliary roller 32 from obstructing the conveyance of the base 2 .
- the leading edge of the film 24 is clamped between the holding roller 72 and the base guide roller 71 , the leading edge of the film 24 can be disposed below the conveyance surface.
- the downstream side edge of the base 2 pushes the film 24 to the downstream side, the leading edge of the film 24 is separated from the base guide roller 71 and the holding roller 72 . Therefore, it is possible to bond the film 24 only to a downstream side part of the bottom surface of the base 2 . Thus, it is possible to effectively inhibit the film 24 from being bonded to the entire bottom surface of the base 2 .
- the packaging device 1 is provided with the detection portion 43 in the section where the first path and the conveyance surface intersect with each other. Therefore, if the user approaches the base 2 in the vicinity of the conveyance portion 40 , it is possible to automatically start the conveyance of the base 2 by the conveyance portion 40 . Further, when the packaging of the base 2 and the article 3 is complete, the conveyance portion 40 automatically stops the conveyance of the base 2 . It is thus possible to improve operation convenience of the packaging device 1 by the user.
- the packaging device may include a member having another structure, such as two rod-like members that can clamp the film 24 in the left-right direction, for example.

Description
- This Application claims priority to Japanese Patent Application No. 2012-107104, filed on May 8, 2012, the content of which is hereby incorporated by reference.
- The present disclosure relates to a packaging device that packages an article by covering the article placed on a mat board with a film, together with the mat board.
- A packaging device is known that packages an article by covering the article placed on a board, such as cardboard, with a film. The packaging device places the film over the upper side of the article, and causes the edge of the film to reach around to a surface (hereinafter referred to as a back surface) of the board opposite to the side on which the article is placed. The edge of the film is fixed to the back surface of the board. A tension is applied to the film and the article is fixed onto the board by the film. The film is in close contact with the article and an operator cannot directly touch the article from the outside. The article is protected by the film.
- For example, a technology is disclosed in which a receiving member that guides the film goes around the periphery of the article and thereby causes the film to be firmly attached to the periphery of the article. By applying this technology to the above-described packaging device, the packaging device can cause the film to be firmly attached to the periphery of the article placed on the board.
- When the above-described technology is applied to the packaging device, unless the path of the receiving member that goes around is larger than the article, it is not possible to package the article with the film. For that reason, in order to have a structure that can package a large article, the size of the packaging device has to be increased.
- In light of the foregoing, the present disclosure provides a packaging device which has a compact size and which is capable of packaging a relatively large article with a film.
- Exemplary embodiment provides a packaging device that includes a conveyance portion, a first guide portion, a first movement portion and a second movement portion. A conveyance portion conveys a base on which an article is placed. A first guide portion guides a film supplied from a first side and is configured to move along a first path and a second path. The first side is a side on which the article is placed in the conveyance path through which the base conveyed by the conveyance portion passes. The first path is a path extending from the first side with respect to the conveyance path toward a second side that is an opposite side to the first side. The second path is a path extending from an upstream side to a downstream side in a conveyance direction on the second side with respect to the conveyance path. A first movement portion causes the first guide portion to move from the first side to the second side along the first path when an upstream side edge in the conveyance direction of the base, which is conveyed from the upstream side toward the downstream side in the conveyance direction with respect to the film, reaches the downstream side in the conveyance direction of a position at which the first path and the conveyance path intersect with each other. A second movement portion causes the first guide portion to move from the upstream side to the downstream side in the conveyance direction along the second path after the first guide portion has been moved to the second side by the first movement portion.

As shown inFIG. 8 , in a state in which thedetachment switching portion 35 has moved downward with respect to theroller support portion 34, theshaft presser portion 351 presses, from above, the right end of the shaft portion of theguide roller 31 supported by theshaft receiving portion 341 of theroller support portion 34. The right end of the shaft portion of theguide roller 31 fits into the recessed portion of the lower end of theshaft presser portion 351. In this state, the shaft portion of theguide roller 31 cannot be detached from thefirst support portion 331. - The
detachment switching portion 35 is provided with a protrudingportion 353 on the downstream side end thereof. The protrudingportion 353 protrudes to the downstream side. The lower end of the protrudingportion 353 comes into contact with aregulation portion 151 in the course of the downward movement of thefirst support portion 331 from the topmost side of theslit 121. As shown inFIG. 7 , theregulation portion 151 protrudes to the left from the left surface of theside plate portion 111. Thedetachment switching portion 35 is provided with theregulation portion 151 on the downstream side of theslit 121, in the vicinity of the bottom of theslit 121. As the lower end of the protrudingportion 353 comes into contact with theregulation portion 151, the downward movement of thedetachment switching portion 35 is regulated. In this case, only theroller support portion 34 moves downward. As shown inFIG. 10 , thedetachment switching portion 35 moves upward with respect to theroller support portion 34. Theshaft presser portion 351 is separated from the shaft portion of theguide roller 31 that is supported by theshaft receiving portion 341 of theroller support portion 34. In this state, the shaft portion of theguide roller 31 can be detached from thefirst support portion 331. - Note that the structure and the operation of the
first support portion 332 are the same as the structure and the operation of thefirst support portion 331 described above. - The
second support portion 51 will be explained with reference to FIG. 11. Thesecond support portion 51 is provided with abridge portion 511,upright portions portions shaft receiving portions bridge portion 511 has a generally rectangular plate shape that is longer in the left-right direction. The length of thebridge portion 511 in the left-right direction is shorter than the distance between theside plate portions 11. Theupright portions bridge portion 511, respectively. The extendingportion upright portions shaft receiving portions upright portions upright portions 52. The extendingportions 531 and 533 are collectively referred to as extendingportions 53. Theshaft receiving portions shaft receiving portions 54. - The
second support portion 51 is provided with arod portion 551 that extends to the right from the right surface of theupright portion 521. Thesecond support portion 51 is provided with arod portion 552 that extends to the left from the left surface of theupright portion 522. Therod portions slits 123 and 124 (refer toFIG. 9 ) that are provided in theside plate portions rod portions slits - Arrangements of the
first support portion 33 and thesecond support portion 51 etc. in the third state (FIG. 7 ,FIG. 8 ), the fourth state (FIG. 9 ,FIG. 10 ) and the fifth state (FIG. 12 ,FIG. 13 ) will be explained with reference toFIG. 7 toFIG. 10 ,FIG. 12 andFIG. 13 . - In the third state, as shown in
FIG. 7 andFIG. 8 , theupright portions 52 of thesecond support portion 51 located on the uppermost stream side are located on both the left and right sides of the holdingportion 61. The extendingportions 53 are located on both the left and right sides of thebase guide roller 71. Theshaft receiving portions 54 are located on both the left and right sides of the holdingroller 72. Theshaft receiving portions 54 are located directly below theguide roller 31 supported by thefirst support portion 33 that has moved to the topmost side. - In the fourth state, as shown in
FIG. 9 andFIG. 10 , the holdingportion 61 swings and the holdingroller 72 is separated from the base guide roller 71 (refer toFIG. 8 ). Thefirst support portion 33 moves to the lowermost side, and theshaft receiving portion 341 of theroller support portion 34 is located below theshaft receiving portion 54 of thesecond support portion 51. Therefore, theshaft receiving portion 54 supports, from below, the shaft portion of theguide roller 31 in place of theshaft receiving portion 341. The shaft portion of theguide roller 31 is separated from theshaft receiving portion 341. In the course of the movement of thefirst support portion 33 to the lowermost side, downward movement of thedetachment switching portion 35 of thefirst support portion 33 is regulated by theregulation portion 151. Thedetachment switching portion 35 moves upward with respect to theroller support portion 34. Theguide roller 31 becomes detachable from thefirst support portion 33. Theauxiliary roller 32 is located above thebase guide roller 71. - In the fifth state, as shown in
FIG. 12 andFIG. 13 , as thesecond support portion 51 moves to the lowermost stream side, theguide roller 31 supported by theshaft receiving portion 54 is separated from thefirst support portion 33. Theguide roller 31 is located in an upstream vicinity of thebase guide roller 73. The blade portion 771 (refer toFIG. 8 ) that protrudes from the cuttingportion 77 is located on the upstream side of theguide roller 31. Note that, even when thesecond support portion 51 has moved to the lowermost stream side, thefirst support portion 33 supports theauxiliary roller 32. Theauxiliary roller 32 is maintained in the vicinity of a position where theguide roller 31 moves from thefirst support portion 33 to thesecond support portion 51, namely, the position where the first path and the second path intersect with each other. - Operations of the packaging device 1 when the packaging device 1 packages the
base 2 and thearticle 3 with thefilm 24 will be explained with reference toFIG. 14 toFIG. 25 .FIG. 14 toFIG. 18 ,FIG. 24 andFIG. 25 each show the third state.FIG. 19 andFIG. 23 each show the fourth state.FIG. 20 toFIG. 22 each show the fifth state. -
FIG. 14 shows a state of the packaging device 1 before the packaging is started. The user swings the first receivingtray 12 and the second receivingtray 13 to establish the first state. The receiving surface of the first receivingtray 12 and the receiving surface of the second receivingtray 13 form aconveyance surface 93. The user moves the second extendingportions 163 and 167 (refer toFIG. 1 ) of theguide portion 16 to the outside in the left-right direction of the first receivingtray 12. Anarrow 91 shows the first path and anarrow 92 shows the second path. Hereinafter, the first path and the second path are referred to as thefirst path 91 and thesecond path 92. The first support portion 33 (refer toFIG. 5 ) is located on the uppermost side, and theguide roller 31 is located at the uppermost position of the first path. Thesecond support portion 51 is located on the uppermost stream side. The cuttingportion 77 is located on the left end. Theconveyance rollers 41 do not rotate. - The
film cassette 21 is provided with afilm guide roller 23 in the vicinity of thefilm discharge opening 26. Thefilm guide roller 23 has a column shape. Thefilm guide roller 23 extends in the left-right direction. Thefilm 24 fed out from thefilm roll 22 comes into contact with a side peripheral surface on the upstream side of the column-shapedfilm guide roller 23. Thefilm guide roller 23 guides thefilm 24 toward thefilm discharge opening 26. The film discharge opening 26 discharges thefilm 24 below thefilm cassette 21. The packaging device 1 is provided with a clutch spring in a portion that supports thefilm cassette 21. The clutch spring applies a torque in a direction opposite to the rotation direction of thefilm roll 22 when the film discharge opening 26 discharges thefilm 24. - First, the user manually pulls out the
film 24 discharged from the film discharge opening 26 of thefilm cassette 21, in the downward direction. The user pulls out an edge (hereinafter referred to as a leading edge of the film 24), on the opposite side to thefilm discharge opening 26, of the pulled outfilm 24 until the leading edge is below theconveyance surface 93, and disposes the leading edge of thefilm 24 in a downstream vicinity of thebase guide roller 71. The user operates the packaging device 1 such that the holdingportion 61 swings and the holdingroller 72 is disposed in the downstream vicinity of thebase guide roller 71. The leading edge of thefilm 24 pulled out from thefilm cassette 21 is clamped from both sides in the conveyance direction by thebase guide roller 71 and the holdingroller 72. Thefilm 24 extends in the up-down direction between theside plate portions 11, and thefilm 24 and theconveyance surface 93 intersect with each other. The torque is applied to thefilm roll 22 by the clutch spring and tension is thus applied to thefilm 24. Thefilm 24 extends in a straight manner in the up-down direction. - As shown in
FIG. 15 , the user places the plate-shapedbase 2, on which thearticle 3 is placed, on the receiving surface of the second receivingtray 13. A cardboard board is an example of thebase 2. The user sends thebase 2 toward the downstream side. The downstream side edge of thebase 2 moves on the second receivingtray 13 and thebase guide roller 71 in order. The downstream side edge of thebase 2 gradually approaches thefilm 24 that is extending in the up-down direction. The downstream side edge of thebase 2 comes into contact with thefilm 24, and after that, passes through over the holdingroller 72. - Further, the user sends the
base 2 toward the downstream side. The downstream side edge of thebase 2 pushes thefilm 24 to the downstream side. The downstream side edge of thebase 2 approaches the first path 91 (refer toFIG. 14 ) from the upstream side, and passes over thefirst path 91 from the upstream side toward the downstream side. The detection portion 43 (refer toFIG. 1 ), which is provided in a section where thefirst path 91 and the conveyance surface intersect with each other, detects the downstream side edge of thebase 2. The packaging device 1 starts to rotate theconveyance rollers 41. The downstream side edge of thebase 2 reaches theconveyance portion 40. Theconveyance portion 40 clamps the left and right edges of thebase 2 in the up-down direction. The urgingrollers 42 urge thebase 2 downward and press thebase 2 against theconveyance rollers 41. Theconveyance rollers 41 rotate without running idle. Theconveyance portion 40 conveys thebase 2 toward the downstream side. Thebase 2 moves further to the downstream side. - As shown in
FIG. 16 , as thebase 2 moves to the downstream side, the downstream side edges of thebase 2 and thearticle 3 come into contact with thefilm 24. Thefilm 24 is bent at the contact portion with thebase 2 and the contact portion with thearticle 3. Thefilm 24 is fed out from thefilm cassette 21 little by little. Due to the torque applied to thefilm roll 22, thefilm 24 is strongly pressed against the downstream side of thebase 2 and thearticle 3. Thefilm 24 is firmly attached to thebase 2 and thearticle 3 in a position where thefilm 24 covers the downstream side of thebase 2 and thearticle 3. - Since a force toward the downstream side is applied to the
film 24, the leading edge of thefilm 24 is separated from thebase guide roller 71 and the holdingroller 72. The leading edge of thefilm 24 moves along with thebase 2 and passes through between thebase 2 and the holdingroller 72. The holdingroller 72 presses the leading edge of thefilm 24 against the bottom surface of thebase 2, from below. The leading edge of thefilm 24 is bonded to the bottom surface of thebase 2 on the downstream side of thebase 2. - The
conveyance portion 40 continuously conveys thebase 2 to the downstream side. The downstream side edge of thebase 2 enters thegroove portions 164 and 168 (refer toFIG. 1 ) of the second extendingportions guide portion 16 from the upstream side, and moves to the downstream side along thegroove portions film roll 22 by the clutch spring and the tension acts on thefilm 24. Therefore, in accordance with the movement of thebase 2, an upward force acts on the downstream side edge of thebase 2 to which the leading edge of thefilm 24 is bonded. In contrast to the upward force, thegroove portions base 2 from above, and thereby inhibit thebase 2 from lifting upward. - The second extending
portions guide portion 16 have moved to the outside in the left-right direction of the first receivingtray 12. As shown inFIG. 1 , the positions in the left-right direction of the second extendingportions side plate portions portions side plate portions tray 12 is inhibited by the upstream side ends of the second extendingportions side plate portions base 2 acts on thegroove portions tray 12 via theguide portion 16, it is possible to inhibit the first receivingtray 12 from lifting upward. Thus, the packaging device 1 can reliably convey thebase 2 along the conveyance surface. Further, the packaging device 1 can inhibit thebase 2 from lifting upward by thegroove portions portions guide portion 16. It is therefore possible to appropriately convey thebase 2 with a simple structure. - The
conveyance portion 40 continuously conveys thebase 2 to the downstream side. As shown inFIG. 17 , thefilm 24 is located in the position where thefilm 24 covers the upper side of thebase 2 and thearticle 3. Theguide roller 31 and theauxiliary roller 32 are located above thefilm 24. Thefilm 24 is firmly attached to the top surface of thearticle 3 due to the torque applied to thefilm roll 22. The upstream side edge of thebase 2 passes through on thebase guide roller 71 and the holdingroller 72. Further, theconveyance portion 40 conveys thebase 2 to the downstream side. The upstream side edge of thebase 2 passes over the first path 91 (refer toFIG. 14 ). - After the upstream side edge of the
base 2 has passed through thefirst path 91, the detection portion 43 (refer toFIG. 1 ), which is provided in the position where thefirst path 91 and the conveyance surface intersect with each other, no longer detects thebase 2. The packaging device 1 determines that the upstream side edge of thebase 2 has passed thedetection portion 43. This means that the upstream side edge of thebase 2 has moved to the downstream side with respect to thefirst path 91. The packaging device 1 stops the rotation of theconveyance rollers 41. The movement of thebase 2 is stopped. - As shown in
FIG. 18 , after the movement of thebase 2 is stopped, the packaging device 1 causes the holdingportion 61 to swing in a direction in which the holdingroller 72 is separated from thebase guide roller 71. The holdingroller 72 is separated from thebase guide roller 71. - Next, as shown in
FIG. 19 , the packaging device 1 moves thefirst support portion 33, which is holding theguide roller 31 and theauxiliary roller 32, from the uppermost side to the lowermost side. Theguide roller 31 moves from the uppermost side to the lowermost side along the first path 91 (refer toFIG. 14 ) in a state in which theguide roller 31 is in contact, from above, with thefilm 24 disposed below. Theguide roller 31 guides thefilm 24 downward and disposes thefilm 24 in a position at which thefilm 24 covers the upstream side of thebase 2 and thearticle 3. Due to the movement of thefirst support portion 33, theguide roller 31 is located on the downstream side of thebase guide roller 71 and theauxiliary roller 32 is located above thebase guide roller 71. InFIG. 18 , the holdingroller 72 is separated from thebase guide roller 71 due to the swinging movement of the holdingportion 61. Therefore, even when theguide roller 31 moves to the lowermost side of thefirst path 91, theguide roller 31 does not come into contact with the holdingroller 72. - As the
first support portion 33 moves to the lowermost side, theguide roller 31 moves from thefirst support portion 33 to the second support portion 51 (refer toFIG. 10 ). In place of thefirst support portion 33, thesecond support portion 51 supports theguide roller 31. Theguide roller 31 becomes detachable from the first support portion 33 (refer toFIG. 10 ). - Next, as shown in
FIG. 20 , the packaging device 1 moves thesecond support portion 51 from the uppermost stream side to the lowermost stream side. Theguide roller 31 is separated from thefirst support portion 33, and moves from the uppermost stream side to the lowermost stream side along the second path 92 (refer toFIG. 14 ). Theguide roller 31 moves to the lowermost stream side along thesecond path 92 in a state in which thefilm 24 is wound around the top and bottom side surfaces and the downstream side surface of theguide roller 31. The top side surface of theguide roller 31 moves on the upstream side of thebase 2 in the vicinity of the bottom surface of thebase 2. Theguide roller 31 is located in the vicinity of and on the upstream side of thebase guide roller 73. Note that, since thefirst support portion 33 continues to support theauxiliary roller 32, theauxiliary roller 32 remains located above thebase guide roller 71 and does not move. - As shown in
FIG. 21 , thefilm 24 extends downward from the position at which thefilm 24 covers the upstream side of thebase 2 and thearticle 3, comes into contact with the upstream edge of thebase 2, and bends to the downstream side along the bottom surface of thebase 2. In the course of the movement of theguide roller 31 to the lowermost stream side, theguide roller 31 presses thefilm 24 against the bottom surface of thebase 2. Therefore, thefilm 24 is bonded to the bottom surface of thebase 2 on the upstream side of thebase 2. - The
film 24 is wound from above theguide roller 31 and bends to the downstream side. Thefilm 24 extends to the upstream side from the bottom side surface of theguide roller 31 toward theauxiliary roller 32 that is disposed above thebase guide roller 71. Thefilm 24 is bent upward by being wound on theauxiliary roller 32, and extends toward the film cassette 21 (refer toFIG. 1 ) that is the supply source of thefilm 24. Since thebase 2 has already passed above thebase guide roller 71 toward the downstream side, thefilm 24 that extends from theguide roller 31 toward thefilm cassette 21 does not come into contact with thebase 2. Therefore, theauxiliary roller 32 inhibits thefilm 24 from coming into contact with thebase 2 that is being conveyed. - After the
guide roller 31 has moved to the lowermost stream side, the packaging device 1 moves the cuttingportion 77 along the guide rails 74 from the left end to the right end. Theblade portion 771 moves on the upstream side of theshaft receiving portion 54 of thesecond support portion 51, below the extendingportion 53. Theblade portion 771 cuts a section of thefilm 24 that extends to the upstream side from theguide roller 31 toward theauxiliary roller 32, from below in the left-right direction. The cuttingportion 77 can cut off a part of thefilm 24 that is covering thebase 2 and thearticle 3, from the remaining part of thefilm 24 that is wound around thefilm roll 22. Note that, since the torque is applied to thefilm roll 22, the tension is applied to thefilm 24 that extends from theguide roller 31 toward theauxiliary roller 32. Therefore, theblade portion 771 can appropriately cut thefilm 24. After thefilm 24 is cut, the edge (cut by the blade portion 771) of thefilm 24 extending from thefilm cassette 21 hangs below thebase guide roller 71, as shown inFIG. 22 . - Both the edges of the
film 24 that has been cut off from thefilm roll 22 are bonded to the bottom surface of thebase 2. Thearticle 3 is fixed to thebase 2 by the cut-off film 24. Thefilm 24 is in close contact with thearticle 3 and an operator cannot directly touch thearticle 3 from the outside. Thearticle 3 is protected by thefilm 24. The packaging of thebase 2 and thearticle 3 with thefilm 24 is complete. - Next, as shown in
FIG. 23 , the packaging device 1 moves thesecond support portion 51 to the uppermost stream side. Theguide roller 31 moves to the uppermost stream side along the second path 92 (refer toFIG. 14 ), and is located on the downstream side of thebase guide roller 71. The packaging device 1 restarts the rotation of theconveyance rollers 41. Theconveyance portion 40 restarts the conveyance of thebase 2. Thebase 2 and thearticle 3 for which the packaging is complete are conveyed to the downstream side and are placed on the first receivingtray 12. The packaging device 1 stops the rotation of theconveyance rollers 41 and the conveyance of thebase 2 and thearticle 3 is complete. - As shown in
FIG. 24 , the packaging device 1 moves thefirst support portion 33 from the lowermost side to the uppermost side. In the course of the movement, theguide roller 31 moves from thesecond support portion 51 to the first support portion 33 (refer toFIG. 10 ). In place of thesecond support portion 51, thefirst support portion 33 supports theguide roller 31. Further, theguide roller 31 is unable to be detached from the first support portion 33 (refer toFIG. 10 ). Theguide roller 31 and theauxiliary roller 32 move from the lowermost side to the uppermost side along the first path 91 (refer toFIG. 14 ). As shown inFIG. 25 , the packaging device 1 swings the holdingportion 61 so that the holdingroller 72 is located on the downstream side of thebase guide roller 71. The edge of thefilm 24 cut by the cuttingportion 77 is clamped by thebase guide roller 71 and the holdingroller 72. Therefore, it becomes possible to package thenext base 2 and thenext article 3 with thefilm 24. - As explained above, the
guide roller 31 of the packaging device 1 moves along the first path and the second path, and packages thebase 2 and thearticle 3 with thefilm 24. In the packaging device 1, theguide roller 31 moves along the two movement paths (the first path and the second path) and packaging is performed. Therefore, there is no need to move theguide roller 31 around the entire periphery of thebase 2 and thearticle 3. It is therefore possible to reduce the size of the structure that causes theguide roller 31 to move along the movement paths. Although the packaging device 1 is a compact device, it can package thearticle 3 having a large size with thefilm 24. - Since the
first support portion 33 moves along theslits guide roller 31, thefirst support portion 33 can move theguide roller 31 along the first path. Further, since thesecond support portion 51 moves along theslits guide roller 31, thesecond support portion 51 can move theguide roller 31 along the second path. Since theguide roller 31 guides thefilm 24 while the cylindrical portion of theguide roller 31 is rotating, it is possible to reduce friction between theguide roller 31 and thefilm 24 to a minimum. Therefore, the packaging device 1 can inhibit excessive tension from being applied to thefilm 24 by the friction between theguide roller 31 and thefilm 24, and it is thus possible to inhibit thefilm 24 from breaking. Further, theguide roller 31 is detachably provided with respect to thefirst support portion 33 and thesecond support portion 51. Thus, theguide roller 31 can easily move between thefirst support portion 33 and thesecond support portion 51. - Further, the
detachment switching portion 35 of thefirst support portion 33 switches between a state in which theguide roller 31 is detachable from theroller support portion 34 and a state in which theguide roller 31 is not detachable from theroller support portion 34. Therefore, when thefirst support portion 33 switches to the state in which theguide roller 31 is not detachable, thefirst support portion 33 can reliably cause theguide roller 31 to guide thefilm 24. Note that, when thefirst support portion 33 switches to the state in which theguide roller 31 is detachable, theguide roller 31 can easily move between thefirst support portion 33 and thesecond support portion 51. Note that the switching between the state in which theguide roller 31 is detachable and the state in which theguide roller 31 is not detachable is performed by theregulation portion 151 regulating the movement of thedetachment switching portion 35. Therefore, by adjusting the position in which theregulation portion 151 is provided, it is possible to easily switch between the state in which theguide roller 31 is detachable and the state in which theguide roller 31 is not detachable, at an appropriate timing. - The
first support portion 33 moves theauxiliary roller 32 in the up-down direction, in addition to theguide roller 31. In a state in which thebase 2 is on the upstream side with respect to the first path, theauxiliary roller 32 is located above the conveyance surface. After thebase 2 has moved to the downstream side with respect to the first path, theauxiliary roller 32 is located above thebase guide roller 71. The packaging device 1 can therefore effectively inhibit theauxiliary roller 32 from obstructing the conveyance of thebase 2. - Further, since the leading edge of the
film 24 is clamped between the holdingroller 72 and thebase guide roller 71, the leading edge of thefilm 24 can be disposed below the conveyance surface. Thus, in the course of the conveyance of thebase 2 from the upstream side to the downstream side, it is possible to appropriately dispose thefilm 24 in a position where thefilm 24 covers the downstream side and the upper side of thebase 2 and thearticle 3, and it is thus possible to firmly attach thefilm 24 to thebase 2 and thearticle 3 in an appropriate manner. - Further, when the downstream side edge of the
base 2 pushes thefilm 24 to the downstream side, the leading edge of thefilm 24 is separated from thebase guide roller 71 and the holdingroller 72. Therefore, it is possible to bond thefilm 24 only to a downstream side part of the bottom surface of thebase 2. Thus, it is possible to effectively inhibit thefilm 24 from being bonded to the entire bottom surface of thebase 2. - The packaging device 1 is provided with the
detection portion 43 in the section where the first path and the conveyance surface intersect with each other. Therefore, if the user approaches thebase 2 in the vicinity of theconveyance portion 40, it is possible to automatically start the conveyance of thebase 2 by theconveyance portion 40. Further, when the packaging of thebase 2 and thearticle 3 is complete, theconveyance portion 40 automatically stops the conveyance of thebase 2. It is thus possible to improve operation convenience of the packaging device 1 by the user. - The present disclosure is not limited to the above-described embodiment, and various modifications are possible. In place of the
guide roller 31, the packaging device may include a member having another structure, such as two rod-like members that can clamp thefilm 24 in the left-right direction, for example. The packaging device may guide thefilm 24 by the two rod-like members moving while clamping thefilm 24. - The
first support portion 33 may switch between the state in which theguide roller 31 is detachable and the state in which theguide roller 31 is not detachable, using a method different from that of the above-described embodiment. For example, thefirst support portion 33 may be provided with a pair of support portions that support both the ends of the axis line of theguide roller 31, from both sides. Further, thefirst support portion 33 may be configured such that it can adjust the distance between one of the support portions and the other support portion. Thefirst support portion 33 may switch between the state in which theguide roller 31 is detachable and the state in which theguide roller 31 is not detachable, by changing the distance between the one of the support portions and the other support portion. - In the above-described embodiment, the
guide roller 31 moves between thefirst support portion 33 and thesecond support portion 51. Then, theguide roller 31 moves along the first path due to the movement of thefirst support portion 33 in the up-down direction, and theguide roller 31 moves along the second path due to the movement of thesecond support portion 51 in the conveyance direction. However, a support portion that can move in the up-down direction and in the conveyance direction may be provided in place of thefirst support portion 33 and thesecond support portion 51. The support portion may move theguide roller 31 in the up-down direction and the conveyance direction while supporting theguide roller 31 such that theguide roller 31 is not detachable. Thus, the support portion may move theguide roller 31 along the first path and the second path. - The cutting
portion 77 may include scissors in place of theblade portion 771. The cuttingportion 77 may cut thefilm 24 using the scissors. The cuttingportion 77 may cut a section of thefilm 24 other than the section of thefilm 24 that extends from theguide roller 31 toward theauxiliary roller 32. For example, the cuttingportion 77 may cut a section of thefilm 24 that is bonded to the bottom surface of thebase 2. A blade portion that extends in the left-right direction may be provided in place of the cuttingportion 77. A configuration may be adopted in which, after thebase 2 and thearticle 3 are packaged, the user can manually cut thefilm 24 by pressing thefilm 24 against the blade portion. - The
auxiliary roller 32 may be supported by a separate member that is different from thefirst support portion 33 and that can move in the up-down direction. Theauxiliary roller 32 in the fourth state may be located in a position other than above thebase guide roller 71. For example, theauxiliary roller 32 may be located on the downstream side of thebase guide roller 71. - In the above-described embodiment, the leading edge of the
film 24 is clamped between thebase guide roller 71 and the holdingroller 72, and thus the leading edge of thefilm 24 is held below the conveyance surface. However, the leading edge of thefilm 24 may be held below the conveyance surface by bonding the leading edge of thefilm 24 to thebase guide roller 71. - In the above-described embodiment, the packaging device 1 controls the rotation of the
conveyance rollers 41 by thedetection portion 43 detecting thebase 2. However, thedetection portion 43 may detect thearticle 3. The packaging device 1 may start the rotation of theconveyance rollers 41 when thedetection portion 43 detects thearticle 3, and the packaging device 1 may stop the rotation of theconveyance rollers 41 when thedetection portion 43 does not detect thearticle 3. - In the above-described embodiment, the
base 2 has a plate shape. However, thebase 2 may have another shape. For example, thebase 2 may have a dish shape in which an upright portion is provided around a plate-shaped portion. Thefilm 24 may be supplied from other than thefilm cassette 21. For example, thefilm 24 may be supplied from outside the packaging device 1. - The
guide roller 31 and theauxiliary roller 32 may be structured such that they each include a column portion and a shaft portion that extends from both the ends of the column portion toward both sides in the axial direction. Thefirst support portion 33 and thesecond support portion 51 may support theguide roller 31 and theauxiliary roller 32 by rotatably supporting their shaft portions. Even with this type of structure, since the column portions come into contact with thefilm 24 while the column portions are rotating, it is possible to reduce the friction between thefilm 24 and theguide roller 31 and theauxiliary roller 32 to a minimum. - In place of the
groove portions portions guide portion 16 may respectively include third extending portions that extend to the inner side in the left-right direction of the first receivingtray 12. The third extending portions may cover, from above, both the left and right edges of thebase 2 for which the packing is complete. In a similar manner to thegroove portions base 2 from lifting upward.
