Description

  The present invention relates to a packaging apparatus and a packaging method for creating a package in which an article to be packaged is packaged in a resin film.

  The envelope made of a resin film used in direct mail or the like is, for example, a process of folding a film strip wound in a roll shape using a folding device, and welding an overlapping portion of the film strip using a welding mechanism. The process, the step of fusing the downstream end of the film strip in the transport direction using the fusing mechanism, the step of loading the packaged material therein, and the upstream end of the film strip in the transport direction using the fusing mechanism It is created by repeating the process of fusing (see, for example, Patent Document 1).

  In an envelope made of a resin film used for direct mail or the like, it is common that flat papers such as magazines, catalogs, and brochures are packaged as packages. An article that is separate from the packaged article and is smaller than the packaged article (hereinafter referred to as a separate accessory), such as a souvenir such as a ballpoint pen or health food, a promotional product, or a sample, is the packaged article. There is a need for a package that can be packaged together.

  When creating a package in which a separate accessory is loaded on the flat surface of the package, a local bulge occurs at the separate accessory. Has a step corresponding to the height. Therefore, in the package body in which the separate accessory is loaded in advance on the package object, the flatness on the flat surface of the package object is impaired.

  When a small object is loaded in advance on the flat surface of the packaged object and welding is performed in a state where the flat surface of the packaged product has a step, it is placed on the flat surface of the packaged object in the transporting process of the packaging device. The loaded small object moves on the flat surface of the package. Therefore, there is a problem that it is difficult to determine the welding blade of the welding mechanism at an appropriate welding position. Moreover, in the package body which has a level | step difference by loading separately a small object beforehand, there also exists a problem that a separate small object may be damaged by the nip part, a welding blade, etc. in a conveyance roller pair. From the above, the present situation is that it is difficult to prepare a package having a step on the flat surface of the packaged object by packaging the packaged object and the separate accessory together in advance.

  By the way, patent document 2 is the cutting which opened by not performing welding on the part in which the protrusion part of a product is located by the cutting blade provided in the cutting blade in the packaging apparatus which shrink-wraps a product with a heat-shrinkable film. Disclose the edge. The packaging apparatus of patent document 2 has the protrusion part which protruded from a part of goods, and is for packaging in the form which protruded the protrusion part outside the film through the cutting edge part.

JP2013-121879A Japanese Patent Laid-Open No. 06-32330

  In Patent Document 2, the opened cutting edge is a window for projecting a certain product loaded in the film to the outside of the film. The position of the projecting part in the certain product is uniquely determined. In the certain product, the positional relationship between the product body and the projecting part is invariable, and the projecting part moves on the product body. Absent. Therefore, in Patent Document 2, a configuration in which a cutting blade is fixedly attached to a fusing blade is used as means for forming an open cutting edge.

  In Patent Document 2, since the protruding portion constitutes a part of the certain product and is integrated with the product main body, the protruding portion never moves relative to the product main body. Therefore, Patent Document 2 does not cover a separate accessory that is loaded in advance on a flat surface of the certain commodity and is movable on the flat surface.

  Moreover, in patent document 2, the open cutting edge part is formed in the side surface of the conveyance direction upstream, and is not formed in the part which faces the flat surface of this certain goods.

  As described above, the inventor wraps a product in which the position of the projecting portion with respect to the product body is uniquely determined while the projecting portion is exposed to the outside of the film through the cut edge of the side surface as in Patent Document 2 above. Know prior art literature on packaging equipment to do. However, a packaging apparatus and a packaging method for creating a package in which a packaged item and a separate accessory are configured to be packaged together and the separate accessory is movable on a flat surface of the packaged item. The inventor is not aware of the existence of prior art documents relating to

  Therefore, the technical problem to be solved by the present invention is that the packaged article and the separate accessory are configured to be packaged together, and the separate accessory is movable on the flat surface of the packaged article. It is providing the packaging apparatus and packaging method which can obtain.

  As shown in FIG. 4, the film folding member 21 folds the left and right side end portions 1 g of the film strip 101, and the side end portions 1 g are overlapped to form a folded portion 1 h on the film strip 101. It is comprised so that.

  The welding unit 30 includes a welding roller (welding member) 31 configured to be movable in the vertical direction by a rack and pinion. The welding roller 31 has a welding blade that protrudes radially outward from the periphery. The control unit controls the downward movement of the welding roller 31 so that the heated welding roller 31 is pressed against the folding unit 1 h supported on the welding platen 35. As a result, the welded portions 1c and 1d along the transport direction X are formed by welding the planned welded portion 1m (shown in FIG. 6) at the folding portion 1h with heat. That is, by welding the planned welding portion 1m with the heat of the welding roller 31, welding portions such as the front welding portion 1c and the rear welding portion 1d as shown in FIG. 6 are formed.

  The first transport unit 40 includes a first driven roller 41 and a first drive roller 42 that are configured to be movable in the vertical direction by a rack and pinion, and the first driven roller 41 and the first drive roller 42. The film strip 101 sandwiched between the two is conveyed to the front fusing unit 50.

  The fusing unit 50 includes a fusing blade (fusing member) 51 configured to be movable in the vertical direction by a rack and pinion, and a film strip having a folded portion 1 h welded by the heated fusing blade 51. 101 is blown in a direction orthogonal to the conveyance direction X. As a result, the front end and the rear end of the film strip 101 are melted to form the package 1 having the front melted end 1a and the rear melted end 1b as shown in FIG.

  The second transport unit 60 includes a second driven roller 61 and a second drive roller 62 configured to be movable in the vertical direction by a rack and pinion, and the second driven roller 61 and the second drive roller 62. The film strip 101 sandwiched between the two is conveyed to the discharge unit 14.

  3A to 3O are schematic diagrams for explaining the operations of the welding roller 31, the first driven roller 41, the fusing blade 51, and the second driven roller 61 in the packaging unit 13. Hereinafter, the operation in the packaging unit 13 will be described with reference to FIGS. 3A to 3O. FIGS. 3A to 3F are diagrams for explaining the operation in a preparation stage in which a bag-like film strip 101 is prepared in advance from the initial film strip 101, and FIGS. 3G to 3O are bag-like films. It is a figure explaining the packaging operation | movement which packages the to-be-packaged object 110 using the strip | belt shaped object.

  As shown in FIG. 3A, the side end portions 1 g are overlapped with each other by the film folding member 21, whereby the folded portion 1 h is formed on the film strip 101. The lower surface of the film strip 101 is disposed on the transport surface 131 of the packaging unit 13. The folded portion 1 h of the film strip 101 is disposed on the welding platen 35.

  Next, as shown in FIG. 3B, the first driven roller 41 of the first transport unit 40 moves downward, and the film strip 101 is sandwiched between the first driven roller 41 and the first drive roller 42. Thereafter, in order to perform welding at the folding portion 1h, the welding roller 31 of the welding unit 30 moves downward and comes into contact with the folding portion 1h supported on the welding platen 35. The film strip 101 welded at the folding portion 1h is conveyed forward while being sandwiched between the first driven roller 41 and the first drive roller 42. During the forward conveyance process, the front portion of the folding portion 1h (the portion corresponding to the front welding portion 1c) is welded by the welding roller 31. Here, the first drive roller 42 rotates, for example, counterclockwise.

  When the film strip 101 is transported forward by a certain length, as shown in FIG. 3C, the second driven roller 61 of the second transport unit 60 moves downward, and the film strip 101 The first driven roller 41 is moved upward after being sandwiched between the driven roller 61 and the second drive roller 62. That is, the film strip 101 is transferred from the first driven roller 41 and the first drive roller 42 to the second driven roller 61 and the second drive roller 62. The film strip 101 is conveyed forward while being sandwiched between the second driven roller 61 and the second drive roller 62. Here, the second drive roller 62 rotates counterclockwise, for example.

  Next, when the welding roller 31 moves upward to complete the welding of the front portion (the portion corresponding to the front welding portion 1c) of the folded portion 1h, as shown in FIG. 3D, the second driven roller 61 And the 2nd drive roller 62 stops conveyance of the film strip 101. FIG. Then, the fusing blade 51 of the fusing unit 50 moves downward, fusing the film strip 101, and the front fusing end 1a (the fusing portion on the downstream side in the transport direction X) of the film strip 101 is formed. Alternatively, the second driven roller 61 may be raised immediately before the fusing blade 51 of the fusing unit 50 moves downward. If it does so, it can prevent effectively that wrinkles generate | occur | produce in the film strip 101 at the time of fusing. Alternatively, the film strip 101 may be transported immediately before the welding roller 31 of the welding unit 30 moves downward and contacts the film strip 101. If it does so, it can prevent effectively that the hole opening in the film strip 101 occurs at the time of welding.

  Next, as shown in FIG. 3E, the fusing blade 51 moves upward, and then, as shown in FIG. 3F, the second driven roller 61 and the second drive roller 62 are blown out. The downstream portion (unnecessary film sheet body) in the transport direction X is transported forward and removed from the transport surface 131 of the packaging unit 13. Then, the second driven roller 61 moves upward. As a result, a film strip 101 is formed in which the front is formed in a bag shape by the front fusing end 1a and the front welding portion 1c. With the above process, the preparatory operation of previously creating the bag-like film strip 101 for packaging the package 110 from the initial film strip 101 is completed.

  Next, as shown in FIG. 3G, an article 110 to be packaged is loaded into a film strip 101 whose front is configured in a bag shape by the front fusing end 1a and the front welding portion 1c. When the sensor 52 detects the front end portion (the end portion on the downstream side in the transport direction X) of the package object 110, the first driven roller 41 moves downward as shown in FIG. Is loaded by the first driven roller 41 and the first drive roller 42.

  Next, as shown in FIG. 3I, the welding roller 31 moves downward and comes into contact with the film strip 101. When the film strip 101 loaded with the package 110 is conveyed forward while being sandwiched between the first driven roller 41 and the first drive roller 42, the folded portion 1 h is welded by the welding roller 31. .

  In FIG. 3I, when the heated welding roller 31 comes into contact with the film strip 101 at substantially the same time as the film strip 101 is conveyed forward by the first driven roller 41 and the first drive roller 42, the front welding section Subsequent to 1c, a rear weld 1d is formed. However, when the heated welding roller 31 comes into contact with the film strip 101 after a certain period of time has passed since the film strip 101 is transported forward, the welding roller 31 starts from the time when the film strip 101 begins to be transported forward. A non-welded portion 1f (shown in FIGS. 4 and 6) having a certain non-welding length is formed in accordance with the delay time until the start of contact with the film strip 101.

  Therefore, in FIG. 3I, the welding portion 1 d following the front welding portion 1 c is controlled by controlling the timing of starting the forward conveyance of the film strip 101 and the timing of starting the contact of the welding roller 31 with the film strip 101. Or formation of the non-welded portion 1f can be controlled. That is, by controlling the timing of contact and separation of the welding roller 31 with the film strip 101, the rear welding part 1d is formed following the front welding part 1c, and the non-sequentially following the front welding part 1c. It can switch to the case where the welding part 1f is formed. The non-welded portion 1f is formed following the front welded portion 1c formed in advance when the rear end portion of the packaging body 1 immediately before a certain package 1 is cut, and the non-welded portion 1f Subsequently, a rear weld 1d is further formed. As shown in FIGS. 4 and 6, the front welded portion 1 c, the non-welded portion 1 f, and the rear welded portion 1 d can be sequentially formed on the planned welded portion 1 m extending along the transport direction X. In addition, on the planned welding part 1m, when the front welding part 1c is abbreviate | omitted and the non-welding part 1f and the back welding part 1d are formed continuously, the back welding part 1d is abbreviate | omitted and the front welding part 1c, It is also possible to form the non-welded portion 1f continuously.

  As shown in FIG. 3J, when the film strip 101 loaded with the package 110 is conveyed forward by a certain length, the second driven roller 61 moves downward as shown in FIG. 3K. To do. As a result, the film strip 101 loaded with the package 110 is sandwiched between the second driven roller 61 and the second drive roller 62, and then the first driven roller 41 moves upward. The film strip 101 loaded with the package 110 is conveyed forward while being sandwiched between the second driven roller 61 and the second drive roller 62.

  Next, when the sensor 52 detects the rear end portion (the end portion on the upstream side in the transport direction X) of the package 110, as shown in FIG. 3L, the film strip 101 loaded with the package 110 is The second driven roller 61 and the second driving roller 62 are further conveyed forward by a certain length, and the rear end portion of the package 110 is positioned forward of the fusing blade 51. At the same time, the welding roller 31 moves upward.

  Next, as shown in FIG. 3M, the fusing blade 51 moves downward to melt the film strip 101 loaded with the package 110, and in the film strip 101 loaded with the package 110. A rear fusing end 1b (upstream fusing part in the conveying direction X) is formed. As a result, the package 1 in which the package 110 is packaged in the film strip 101 is created. At the same time, the front fusing end 1a (the fusing part on the downstream side in the transport direction X) of the next film strip 101 is also formed.

  Next, as shown in FIG. 3N, the package 1 is conveyed forward while being sandwiched between the second driven roller 61 and the second drive roller 62. Then, as shown in FIG. 3O, the second driven roller 61 moves upward.

  Thereafter, by repeating the operations of FIGS. 3G to 3O, the package 1 in which the package 110 is packaged in the film strip 101 is formed.

  Next, the packaging method of the packaging body 1 according to an embodiment of the present invention will be described in detail and specifically with reference to FIGS.

  In FIG. 5, the article 110 to be packaged is loaded into the film strip 101 having a front portion configured in a bag shape by the front cut end 1a and the front welded portion 1c (step S10).

  Whether the sensor 52 detects the front end of the package 110 (the end on the downstream side in the transport direction X) in order to detect whether the package 110 is loaded up to the front fusing end 1a. The control unit determines whether or not (step S12). When the sensor 52 has not detected the front end portion of the article 110 to be packaged, the controller notifies the user about the error and prompts the user to insert the article 110 to the front fusing end 1a. If the sensor 52 does not detect the front end of the package 110, the welding roller 31, the first driven roller 41, the fusing blade 51, the second driven roller 61, the first driving roller 42, the second driving roller 62, and the like operate. do not do.

  When the sensor 52 detects the front end portion of the article 110, the first driven roller 41 is lowered (step S14). As the first driven roller 41 descends, the film strip 101 loaded with the article 110 is sandwiched by the nip formed by the first driven roller 41 and the first drive roller 42 and conveyed forward. . The control unit determines whether or not the film strip 101 loaded with the package 110 is conveyed with a certain non-welding length (step S18). If the film strip 101 loaded with the package 110 is not conveyed with a certain non-welding length, it is conveyed forward until it is conveyed with a certain non-welding length. The heated welding roller 31 descends from the time when the film strip 101 loaded with the package 110 is sandwiched between the nip portions of the first driven roller 41 and the first drive roller 42, and the film strip 101 is lowered. The non-welded portion 1f following the front welded portion 1c is formed along the planned welded portion 1m until the point of contact with the first welded portion 1c.

  When the film strip 101 loaded with the package object 110 is conveyed with a certain non-welding length, the heated welding roller 31 is lowered and the welding operation is started (step S20). That is, when the heated welding roller 31 is brought into contact with the folding portion 1h, the rear welding portion 1d following the non-welding portion 1f is formed along the planned welding portion 1m.

  The front end portion of the article to be packaged 110 loaded in the film strip 101 is conveyed to the nip portion formed by the second driven roller 61 and the second drive roller 62, and the article to be packaged 110 is second. It is delivered to the nip portion between the driven roller 61 and the second drive roller 62 (step S22). When the front end portion of the article to be packaged 110 is conveyed to the second driven roller 61 and the second drive roller 62, the second driven roller 61 is lowered (step S24). As a result, the film strip 101 loaded with the package object 110 is sandwiched between the nip portions of the second driven roller 61 and the second drive roller 62. Thereafter, the first driven roller 41 rises (step S26), and the nip formed by the nip portion between the first driven roller 41 and the first drive roller 42 is released. As a result, the film strip 101 loaded with the package object 110 is conveyed forward by the nip portion of the second driven roller 61 and the second drive roller 62.

  Next, the control unit determines whether or not the sensor 52 has detected the rear end portion (the upstream end portion in the transport direction X) of the article 110 (step S28). Until the sensor 52 detects the rear end of the package 110, the film strip 101 loaded with the package 110 is conveyed forward by the nip portion of the second driven roller 61 and the second drive roller 62. . When the sensor 52 detects the rear end portion of the package object 110, the film strip 101 loaded with the package object 110 is positioned so that the rear end portion of the package object 110 is located in front of the fusing blade 51. The second driven roller 61 and the second drive roller 62 are conveyed forward by a certain rear end side welding length (step S30). At the same time that the film strip 101 loaded with the package 110 is transported with a certain welding length on the rear end side, the welding roller 31 is raised (step S32), and the welding operation is finished. . Between the start of the welding operation in step S20 and the end of the welding operation in step S32, the rear welding portion 1d for the film strip 101 loaded with the package 110 and the next film strip 101 The front welded portion 1c is formed on the planned welded portion 1m extending in the conveying direction X at the folding portion 1h.

  The second driven roller 61 is lifted (step S34), and the film strip 101 loaded with the package 110 is released from being sandwiched between the nip portions of the first driven roller 41 and the first drive roller 42. Thus, the forward conveyance operation is temporarily stopped. Next, the fusing blade 51 is lowered to cut the film strip 101 loaded with the package 110 (step S36). By the fusing, the rear fusing end 1b (the fusing portion on the upstream side in the transport direction X) is formed in the film strip 101 loaded with the package 110. As a result, the film strip 101 loaded with the package 110 becomes the package 1 in which the package 110 is packaged in the film strip 101. At the same time, as the next film strip 101, a bag-shaped film strip 101 having a front fusing end 1a and a front welded portion 1c is formed.

  The second driven roller 61 descends (step S38), and the forward conveyance of the packaging body 1 by the nip portion of the second driven roller 61 and the second drive roller 62 is resumed. And the package 1 is discharged | emitted by the discharge part 14 (step S40). Thereafter, the second driven roller 61 is raised (step S42), the forward conveying operation is temporarily stopped, and a series of conveying, welding, and fusing operations are completed.

  Thereafter, by repeating the above-described operation, the package 1 in which the package 110 is packaged in the film strip 101 is sequentially formed.

  FIG. 6 shows the package 1 produced by the packaging method described above. As shown in FIG. 6, the package 1 has a folded portion 1 h formed by superimposing the front melted end 1 a and the rear melted end 1 b formed by fusing and the side end portions 1 g of the film strip 101. And having. On the planned welding portion 1m extending in the conveying direction X in the folding portion 1h, a front welding portion 1c and a rear welding portion 1d, and a non-welding portion 1f formed between the front welding portion 1c and the rear welding portion 1d, Is formed.

  By controlling the end position of the front welded portion 1c and the start end position of the rear welded portion 1d, that is, by controlling the timing of contact and separation of the welding roller 31 with respect to the film strip 101, the non-planar welded portion 1m The location of the welding part 1f and the length in the transport direction X can be arbitrarily controlled. Preferably, the non-welded portion 1f is formed at a portion facing the flat surface 111 of the package 110 in order to stabilize welding at the folded portion 1h.

  As shown in FIG. 6, the non-welded portion 1 f of the package 1 has an opening length formed according to a cross-sectional shape orthogonal to the longitudinal direction of the separate accessory 102 such as a ballpoint pen, and the separate accessory 102. It can be used as an opening window for inserting. When the separate accessory 102 is inserted through the non-welded portion 1 f, the packaged object 110 and the separate accessory 102 are packaged together, and the separate accessory 102 is movable on the flat surface 111 of the packaged object 110. Such a package 1 can be obtained.

  In addition, when distributing the package 1 in which the separate accessory 102 is inserted through the non-welded portion 1f as described above at an exhibition or the like, it is not particularly necessary to close the non-welded portion 1f. However, when the packaging body 1 into which the separate accessory 102 is inserted through the non-welded portion 1f is delivered using a delivery company, processing is performed so that the non-welded portion 1f does not open with a predetermined size or more. It may be required to apply. In that case, after creating the package 1 having the non-welded portion 1f, a post-adhesion means or a post-adhesion step for adhering the non-welded portion 1f can be provided.

  When the non-welding length of the non-welding portion 1f is equal to or longer than a predetermined length, for example, a process of closing the non-welding portion 1f in whole or in part using an adhesive tape or an adhesive as a post-adhesion means. Done. Alternatively, a hand sealer or handy sealer as a post-adhesion means is arranged as an accessory of the packaging device 10 on the front side of the packaging device 10 (downstream in the transport direction X), and a non-welded portion is used using a hand sealer or the like 1f may be welded in whole or in part.

  Moreover, although the non-welded part 1f of the package 1 is used as an opening window for inserting the separate accessory 102 as described above, the bag-shaped package 1 is ruptured by stacking during delivery. It can also be used as an air vent for preventing the above. The non-welded portion 1f of the package 1 can also be used as an opening introduction portion that makes it easy to open the package 1 by inserting a finger therein.

  Furthermore, regarding the location where the non-welding portion 1f is disposed and the length in the transport direction X, it is also possible to input any numerical value desired by the user through the input operation portion of the operation panel.
