Abstract

PROBLEM TO BE SOLVED: To prevent a part of a mark attached to a container from being hidden by an image formed on the outer face of the container or a sticking material stuck to the outer face of the container.SOLUTION: As shown in 4A, the container 20 moves forward while being guided by a left guide 32 because a container placing face 31A is inclined in lateral and longitudinal directions. When a first area R1 is in contact with a resistance applying part 33, a slip between the first area R1 and the resistance applying part 33 is prevented, so that the container 20 moves forward with clockwise rotation (see 4B). As shown in 4C, when a second area R2 is in contact with the resistance applying part 33, a slip occurs between the second area R2 and the resistance applying part 33, so that the rotation of the container 20 stops. Thereafter, the container 20 moves toward a sticking device while the container 20 is guided by the resistance applying part 33.

Description

  The present invention relates to a container manufacturing method and the like.

And such a display apparatus is arrange | positioned in the state inclined, for example so that a container might move ahead of a display case with dead weight of the container itself. When one container on the near side (front row) is extracted, the subsequent container moves to the near side by its own weight.
Here, a plastic flat plate, for example, is provided at a place where the container of the display device is placed because of the good sliding property of the container. In recent years, a display device in which a large number of rotatable rollers are arranged has been proposed (for example, see Patent Document 1). In addition, the container is generally refilled from the rear side of the display device, but the container can be loaded from the front side, and the container moved to the back side is moved to the front side again and displayed. A display device has also been proposed (see, for example, Patent Document 2). Further, as a container, a can has been proposed in which inner concave portions and vertical ribs are alternately formed in the circumferential direction on the inner peripheral wall of an annular convex portion formed on the can bottom (see, for example, Patent Document 3). ).

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a perspective view of a container 20 according to an embodiment of the present invention.
The container 20 according to the present embodiment is a so-called two-piece can and is filled with contents such as a beverage. The container 20 includes a cylindrical container body 21 and a lid member 22 attached to the upper part of the container body 21. The container 20 has an identification mark 23 on the outer peripheral surface of the container main body 21 for distinguishing it from other products such as a product name and a trade name. Two regions having different friction coefficients are formed on the outer peripheral surface of the container body 21 (described later). Furthermore, in this embodiment, a circular seal S (an example of an adhesive material) is attached to the outer peripheral surface of the container body 21. Such a seal S is often affixed when a campaign or the like is executed.

  Here, the seal S is stuck so as not to overlap the identification mark 23. In addition, the seal S does not overlap the identification mark 23 as shown in (A) and (B) of FIG. Is affixed. Further, the seal S is affixed to an area located around the identification mark 23. More specifically, the seal S is pasted at a position where the container 20 is visible when the container 20 is viewed from the side where the identification mark 23 is attached (when the container 20 is viewed from the direction of the arrow X in FIG. 1). . The seal S is affixed to the side where the identification mark 23 is provided among the side where the identification mark 23 is provided and the side opposite to the side where the identification mark 23 is provided.

Next, the manufacturing method of the container 20 will be described in detail.
FIG. 3 is a view showing the container 20 before the seal S is attached. FIG. 2A is a perspective view of the container 20. FIG. 2B shows a cross section at the S portion in FIG. 1A, and FIG. 1C shows a cross section at the T portion in FIG.

  Although the detailed description has been omitted above, the container 20 according to the present embodiment has a first region R1 (an example of a container-side contact portion) on the outer peripheral surface of the container main body 21, as shown in FIG. It has the 2nd field R2. Here, the second region R <b> 2 is formed in the lower portion of the container 20. Moreover, 2nd area | region R2 is formed in the strip | belt shape so that the circumferential direction of the container 20 may be followed. Moreover, in the container 20 in this embodiment, the area | regions other than 2nd area | region R2 among the outer peripheral surfaces of the container main body 21 are 1st area | region R1. The relationship between the second region R2 and the identification mark 23 will be described. The second region R2 and the identification mark 23 are arranged in a state shifted by 90 ° in the circumferential direction of the container 20. In the present embodiment, the friction coefficient on the surface satisfies the first region R1> the second region R2.

Here, the surface state of the second region R2 will be described first with reference to FIG.
As shown in FIG. 5B, an ink layer 51 is provided on the surface of the container body 50 in the second region R2. In addition, a top coat layer (outermost layer) 52 having crater-like irregularities is provided on the surface of the ink layer 51.

  Here, as the ink used for the ink layer 51, for example, one for metal printing can be used. Here, as the pigment (color amount) of the ink, various organic pigments and inorganic pigments are used. The ink vehicle is mainly composed of a resin such as a thermosetting resin or an ultraviolet curable resin. Here, as the thermosetting resin, an alkyd type or polyester type resin or the like is used. As the ultraviolet curable resin, an ultraviolet radical polymerization type resin, an ultraviolet cation polymerization type resin, or the like is used. Furthermore, the ink may contain an additive. Additives include matting agents, waxes (natural, petroleum, synthetic), desiccants, dispersants, wetting agents, crosslinking agents, gelling agents, thickeners, anti-skinning agents, stabilizers, An antifoaming agent, a photopolymerization initiator, or the like is used.

  The ink layer 51 is formed of a so-called repelling ink. That is, the ink layer 51 is formed of ink that repels the paint when the paint for forming the topcoat layer 52 is applied to the surface of the ink layer 51. Here, the unevenness in the top coat layer 52 is formed by repelling the paint forming the top coat layer 52 by the ink layer 51.

  In order to repel the paint for forming the top coat layer 52 by the ink layer 51 (to form the unevenness), the surface tension of the ink used for forming the ink layer 51 is used for forming the top coat layer 52. It is desirable to set 5 mN / m or more lower than the surface tension of the paint. In other words, it is desirable that the surface tension of the ink is lower than the surface tension of the paint, and that the difference in surface tension between the ink and the paint is 5 mN / m or more. Here, the reduction of the surface tension of the ink can be carried out, for example, by adding silicone to normal ink.

  On the other hand, the coating material used for the topcoat layer 52 is mainly composed of a resin such as a thermosetting resin or an ultraviolet curable resin, and contains a wax component as necessary. Thermosetting resins include phenol-formaldehyde resin, furan-formaldehyde resin, xylene-formaldehyde resin, ketone-formaldehyde resin, amino resin, urea formaldehyde resin, melamine-formaldehyde resin, alkyd resin, unsaturated polyester resin, epoxy resin ( Examples: novolac type epoxy resin, bisphenol type epoxy resin), bismaleimide resin, triallyl cyanurate resin, thermosetting acrylic resin, silicone resin, oily resin and the like are used.

  Further, a composition of a thermosetting resin and a thermoplastic resin may be used. In this case, a vinyl chloride-maleic acid-vinyl acetate copolymer, an acrylic polymer, a saturated polyester resin, or the like is used as the thermoplastic resin. These resins can be used singly or in combination of two or more. Moreover, well-known acid catalysts, such as toluenesulfonic acid and benzenesulfonic acid, may be added to these resin compositions as needed. When using an acid catalyst, it is desirable to add the acid catalyst in an amount of 0.5 to 1% by mass based on the resin. Of these resins, it is particularly desirable in terms of coating film performance to use a composition of a melamine-formaldehyde resin and a saturated polyester resin or a composition of a thermosetting acrylic resin and a melamine-formaldehyde resin.

  On the other hand, as the ultraviolet curable resin, for example, a cationic curable resin, a radical curable resin, or the like is used. As the cationic curable resin, a composition of an ultraviolet curable epoxy resin and a cationic photopolymerization catalyst is used.

  Moreover, in the coating material used for the topcoat layer 52, you may add a crosslinking agent and a sensitizer to said resin as needed. As the crosslinking agent, various polyols (eg, ε-caprolactone triol) and the like are used. A thioxanthone derivative or the like is used as the sensitizer. Furthermore, natural, petroleum, or synthetic wax agents may be added alone or in combination as a wax component to the paint used for the top coat layer 52 in order to compensate for slippage. Further, various silicone oils may be added as a leveling agent for the surface of the topcoat layer 52 and / or to further improve the stability in the paint state and to impart initial slipperiness to the topcoat layer 52. good.

An example of the composition of the ink layer 51 and the topcoat layer 52 is as follows.
[Topcoat layer 52]
Resin component: 30% polyester, 13% acrylic, 55% amino, 2% epoxy
Wax: Petroleum 0.3%, Natural 1%, Synthetic 0.2% (based on resin component)
Silicone oil (mixed): 0.15% (based on resin component)
Surface tension: 33 mN / m
Thickness: 5μm
[Ink layer 51] (repellent ink)
Main resin: Alkyd resin Pigment: TiO ₂
Surface tension: 28 mN / m
Thickness: 2μm

  The above is an example of a method for forming the second region R2. For example, the second region R2 may be formed by using a technique disclosed in Japanese Patent Application Laid-Open No. 2002-361172. That is, the second region R <b> 2 may be formed by forming irregularities by agglomerating the coating material forming the top coat layer 52 in the form of spots on the surface of the ink layer 51. Moreover, the crater-like unevenness | corrugation of 2nd area | region R2 can be formed by forming the ink layer 51 using what is called foaming ink containing the foaming agent. As this foaming agent, for example, foamable microcapsules can be used. This foamable microcapsule is obtained by encapsulating a low-boiling hydrocarbon (butane, propane, etc.) in a spherical outer shell made of resin, and the particle size expands several times by heating during the baking process. The unevenness of the second region R2 is on the order of 3 to 10 μm at the maximum depth, and in a normal coating material, a smooth surface with a depth of about 1 μm or less is called the first region R1. .

Next, the surface state of the first region R1 will be described with reference to FIG.
As shown in FIG. 5C, the first layer R1 is provided with an ink layer 51 on the surface of the container body 50 in the same manner as described above. A topcoat layer (outermost layer) 52 having a surface smoother than the topcoat layer 52 in the second region R2 is provided on the surface of the ink layer 51.

  Here, the ink layer 51 in the first region R <b> 1 is formed using an ink (ordinary ink) that does not repel the paint forming the top coat layer 52. In other words, the ink that forms the ink layer 51 is an ink whose surface tension is equal to or higher than the surface tension of the paint that forms the topcoat layer 52. Therefore, in the first region R1, the paint that forms the topcoat layer 52 is not repelled, and the surface of the topcoat layer 52 is smoother than the topcoat layer 52 in the second region R2. The basic composition of the ink that forms the ink layer 51 is the same as described above. The basic composition of the paint for forming the top coat layer 52 is the same as described above.

  In addition, when forming the ink layer 51 in 2nd area | region R2 using the said foamed ink, the ink layer 51 in 1st area | region R1 is formed using the ink (normal ink) which is not foamed ink. When the ink layer 51 in the second region R <b> 2 is formed using an ink that agglomerates the paint that forms the top coat layer 52, the ink layer 51 in the first region R <b> 1 forms the top coat layer 52. It is formed using an ink that does not cause the paint to agglomerate (normal ink).

Next, a production line used for producing the container 20 will be described. If it adds, the manufacturing line of the container 20 after the container 20 is filled with a drink is demonstrated.
FIG. 4 is a view for explaining a production line of the container 20 after the beverage is filled. In the production line of the container 20 of the present embodiment, as shown in FIG. 4, there are a transfer device 30 for transferring the container 20, and a sticking device 70 for applying the seal S to the container 20 that has been transferred by the transfer device 30. Is provided.

  FIG. 5 is a top view of the transport device 30. First, the transport device 30 will be described with reference to FIG. The transport device 30 according to the present embodiment includes a placement unit 31 that places the container 20 and moves the container 20, and a guide 32 that forms a movement path of the container 20 and guides the movement of the container 20. .

  Here, the guide 32 is disposed along the movement path of the container 20. The guides 32 are provided on both sides of the movement path of the container 20. Here, the guide 32 is formed of a metal material such as aluminum or a resin material, for example. Of the two guides 32 provided, the guide 32 positioned on the right side (right side in the figure) of the movement path of the container 20 can be omitted. Here, in the present specification, hereinafter, the right guide 32 in the drawing may be referred to as a right guide 32, and the left guide 32 in the drawing may be referred to as a left guide 32.

  Here, the placement unit 31 has a container placement surface 31A on which the container 20 is placed. And this container mounting surface 31A is inclined and arranged so that the lower side in the figure is positioned below the upper side. In other words, the container placement surface 31A is inclined and disposed such that the container placement surface 31A and the horizontal plane in the front-rear direction form an angle θV (hereinafter sometimes referred to as “front-rear direction inclination angle θV”). Yes.

  The container placement surface 31 </ b> A is disposed so as to be inclined such that the left guide 32 is positioned below the right guide 32. In addition, the container placement surface 31A is inclined so that the container placement surface 31A and the horizontal plane in the left-right direction (width direction) form an angle θH (hereinafter, sometimes referred to as “left-right direction tilt angle θH”). Are arranged. More specifically, in the present embodiment, a resistance applying portion 33 to be described later is provided on one side of the side of the moving path of the container 20 and the other side. And the inclination which falls as it goes to this one side side from this other side side is provided to 31 A of container mounting surfaces in this embodiment. In addition, the code | symbol 3A, 3B in FIG. 5 has shown the state of the inclination in 31 A of container mounting surfaces.

  Further, the placement unit 31 includes a first roller row 311 and a second roller row 312 that are arranged in parallel in the width direction of the placement unit 31 on a container placement surface 31A that is a surface on which the container 20 is placed. ing. Here, the first roller row 311 is provided on the one side, and the second roller row 312 is provided on the other side. Each roller row has a plurality of roll-shaped members 314. In addition, the roll-shaped member 314 included in the first roller row 311 can rotate along the moving direction of the container 20 and smoothly moves the container 20. On the other hand, the roll-shaped member 314 included in the second roller row 312 is fixed so as not to rotate. For this reason, the roll-shaped member 314 included in the second roller row 312 imparts resistance against movement to the container 20 that moves the placement unit 31.

  Here, the roll-shaped member 314 included in the second roller row 312 contacts a part located on the other side of the container 20 (on the side opposite to the side where the resistance applying portion 33 is provided). A drag force is applied to the container 20. In this embodiment, all the roll-shaped members 314 included in the second roller row 312 are fixed so as not to rotate. However, a part of the roll-shaped members 314 is fixed, for example, every other roll-shaped member 314 is fixed. May be. The roll member 314 included in the second roller row 312 can be fixed with an adhesive or the like. A tape or the like can also be attached and fixed. Further, the roll-shaped member 314 included in the second roller array 312 may not be provided, and a convex portion corresponding to the roll-shaped member 314 may be provided on the surface of the placement unit 31.

  Furthermore, in the present embodiment, the left guide 32 has a resistance applying portion 33 (an example of a side contact portion) that applies sliding resistance (friction resistance, drag) to the outer peripheral surface (side portion) of the container 20 that is in contact with the left guide 32. Is provided. This resistance applying portion 33 that also functions as a rotating means is provided along the movement path of the container 20. In addition, the resistance applying portion 33 is provided on one side of the one side and the other side of the moving path. Further, as shown in FIG. 6 (sectional view taken along line VI-VI in FIG. 5), the resistance applying portion 33 is provided along the movement path of the container 20 and is fitted in a groove formed in the left guide 32. It is comprised from the material 33A and the sticking member 33B stuck on the outer surface of this base material 33A.

  Here, as shown in FIG. 6, a portion of the outer surface of the base material 33 </ b> A located on the movement path side of the container 20 is formed to be curved so as to protrude toward the movement path. In addition, the surface located on the movement path side of the container 20 in the outer surface of the base material 33A has a curvature so as to move away from the movement path of the container 20 toward the upper side from the center in the height direction and toward the lower side. It is formed in the state of having. In the present embodiment, the base material 33A is formed in a cylindrical shape, but the base material 33A formed in a semicircular shape may be attached to the left guide 32.

  Here, as described above, when the portion of the outer surface of the base material 33A that is located on the moving path side of the container 20 is formed to be curved, the container 20 that moves on the placement unit 31 moves in the vertical direction or the horizontal direction. Even if inclined, the contact area between the resistance applying portion 33 and the container 20 tends to be constant. The base material 33A can be formed of a hard material such as aluminum, for example. Moreover, the sticking member 33B can be comprised with the vinyl tape comprised by the vinyl chloride, for example. In addition, the sticking member 33B can be made of a material that is more flexible than the base material 33A and softer than the base material 33A.

  In addition, the resistance provision part 33 can be formed only by the hard base material 33A, without providing the sticking member 33B. Further, when the resistance applying portion 33 is configured only by the base material 33A, it is possible to roughen the surface of the base material 33A by performing a sandblasting process as an example of a roughening process on the base material 33A. Moreover, when providing the sticking member 33B, this sticking member 33B can also use rubber members, such as EPDM (ethylene-propylene rubber), for example.

Next, the operation of the container 20 in the transport device 30 will be described.
FIG. 7 is a view for explaining the operation of the container 20 in the transport device 30. In the drawing, the first roller row 311 and the second roller row 312 (see FIG. 5) are not shown.

  As indicated by reference numeral 4A in FIG. 7, the container 20 placed behind the placement unit 31 is provided with an inclination in the left-right direction (width direction) and an inclination in the front-rear direction with respect to the container placement surface 31A. Then, it moves forward while being guided by the left guide 32. At this time, if the first region R1 is in contact with the resistance applying portion 33, slippage between the first region R1 and the resistance applying portion 33 is suppressed (a drag is applied to the first region R1), The container 20 moves forward while rotating clockwise (see reference numeral 4B).

  And if 2nd area | region R2 will be in the state which contacts resistance provision part 33 like code | symbol 4C, a slip will arise between 2nd area | region R2 and resistance provision part 33, and rotation of the container 20 will stop. Here, when 2nd area | region R2 contacts the resistance provision part 33, 2nd area | region R2 and the resistance provision part 33 contact in the state close | similar to a point contact. In other words, the contact area between the second region R2 and the resistance applying portion 33 is reduced. For this reason, it is considered that the slip occurs between the second region R2 and the resistance applying portion 33.

  Thereafter, the container 20 moves toward the sticking device 70 (see FIG. 4) while being guided by the resistance applying portion 33. In the present embodiment, when the container 20 reaches the sticking device 70, the identification mark 23 is directed forward. In addition, in the present embodiment, the second region R2 and the identification mark 23 are arranged with a predetermined positional relationship determined in advance. Specifically, when the second region R2 faces the left side (one direction), the identification mark 23 faces the front (the direction intersecting the one direction, the direction perpendicular to the one direction). Area | region R2 and the identification mark 23 are arrange | positioned. For this reason, when the second region R2 comes into contact with the resistance applying portion 33, the identification mark 23 faces forward (traveling direction).

  In the transport device 30 according to this embodiment, as described above, the roll-shaped member 314 included in the second roller row 312 is fixed so as not to rotate. For this reason, the roll-shaped member 314 included in the second roller row 312 imparts resistance against movement to the moving container 20. Here, in the configuration of the present embodiment, when no drag is applied from the second roller row 312 to the container 20, the container 20 rotates despite the contact between the second region R <b> 2 and the resistance applying portion 33. There is a possibility that. That is, unintentional rotation of the container 20 may occur due to the drag applied from the resistance applying unit 33 to the second region R2. For this reason, in this embodiment, the roll-like member 314 included in the second roller row 312 is used to provide a drag force to the container 20 to suppress the unintended rotation. In other words, a drag is applied to a portion of the container 20 that is located on the opposite side of the portion that contacts the resistance applying portion 33, and excessive rotation of the container 20 is suppressed.

FIG. 8 is a diagram for explaining the sticking device 70. In addition, the figure (A) shows the state at the time of seeing the sticking apparatus 70 grade | etc., From the conveyance direction downstream of the container 20, The figure (B) has shown the state at the time of looking at the sticking apparatus 70 grade | etc., From the upper direction. .
A sticking device 70 as an example of a processing unit is disposed on the side of the movement path of the container 20 and sticks the seal S from the side of the container 20. More specifically, as shown in FIG. 8A, the sticking device 70 holds a strip-like base material BA in which a plurality of seals S are stuck in a row, and the base material BA being wound up. A first reel 71; a second reel 72 that winds up the base material BA; and a bending member 73 that is formed in a wedge shape and bends the base material BA located between the first reel 71 and the second reel 72. ing. In addition, a sticking member 74 for sucking and holding the seal S and sticking the held seal S to the container 20 is provided. In the present embodiment, the seal S is affixed to the container 20 by the affixing member 74, and the container 20 shown in FIG. 1 is completed.

  In the present embodiment, the seal S in a state where a part of the base material BA is bent by the bending member 73 is peeled off from the base material BA. In this embodiment, the seal S is transported to the container 20 using the sticking member 74, and the seal S is stuck on the outer peripheral surface of the container 20. In addition, in the present embodiment, the container 20 is rotated (controlled) so that the identification mark 23 is not positioned at the position where the seal S is applied by the applying device 70. For this reason, the seal S is affixed to a location different from the location where the identification mark 23 is located. As shown in FIG. 1, the seal S is disposed so as to be shifted by about 45 ° with respect to the identification mark 23. For this reason, as shown to FIG. 8 (B), the sticking member 74 also moves to the container 20 with rotation of 45 degrees.

  Here, a method of forming the first region R1 and the second region R2 will be described. The first region R1 and the second region R2 are formed before the container 20 is filled with a beverage. More specifically, 1st area | region R1 and 2nd area | region R2 can be formed in the printing process included in the manufacturing process of the container 20 which is a 2 piece can, for example. In more detail, it can form using the printing machine installed in the printing process.

Here, FIG. 9 is a diagram illustrating a printing machine that performs printing on the container 20.
A printing machine 500 shown in the figure is a printing machine that performs so-called offset printing. The printing machine 500 includes a blanket cylinder 510, an ink application device 520 that has a printing plate corresponding to an image and applies ink for forming the ink layer 51 to the blanket cylinder 510, a support roll 530, and the topcoat layer 52. A paint application device 540 for applying the paint to be applied is provided.

  The blanket cylinder 510 is formed in a disc shape and rotates in one direction. The blanket cylinder 510 has a plurality of blankets (transferred portions) 511 on the outer peripheral surface. In addition, the blanket cylinder 510 transfers the ink transferred from the printing plate in the ink applicator 520 to the blanket 511 to the base can body that is the base of the two-piece can at the transfer portion Te and transfers the ink to the base can body. Form an image.

  A plurality of ink applicators 520 are provided for each color along the circumferential direction of the blanket cylinder 510. Each ink application device 520 includes a printing cylinder 529 that contacts the blanket 511 of the blanket cylinder 510 and an ink supply device 528 that supplies ink to the outer peripheral surface of the printing cylinder 529. Here, the printing cylinder 529 has the above printing plate on its outer peripheral surface, and transfers the ink supplied by the ink supply device 528 to the blanket 511. As a result, ink is placed on the surface of each blanket 511. Specifically, ink is sequentially placed from each of the printing cylinders 529 on each surface assigned to each printing cylinder 529 on the surface of each blanket 511. As a result, an ink image corresponding to the image is formed on the surface of each blanket 511. The ink image moves to the transfer portion Te as the blanket cylinder 510 rotates, and is transferred to the outer peripheral surface of the raw can body rotating in the circumferential direction. As a result, the ink layer 51 is formed.

  The support roll 530 is disposed at a position opposite to the blanket cylinder 510 and rotates in one direction, and conveys the raw can body that has moved from a not-shown washer process to the transfer unit Te. Further, the support roll 530 conveys the raw can body that has moved from the washer process to the transfer unit Te in a rotated state. The coating material coating device 540 applies the coating material to the outer peripheral surface of the element can body (element can body on which the ink layer 51 is formed) to which the ink image is transferred. As a result, the top coat layer 52 is formed.

  Here, when such a printing machine 500 is used, by placing ink having a function of repelling paint from the printing cylinder 529 responsible for the ink layer 51 in the second region R2 on the blanket 511, the second region R2 and A surface difference can be formed between the first region R1 and the first region R1. In addition, formation of 2nd area | region R2 using the foaming ink mentioned above can be performed by putting foaming ink on the blanket 511 from the cylinder 529 for printing which takes charge of the ink layer 51 in 2nd area | region R2. Furthermore, the formation of the second region R2 using the above-described ink for aggregating the paint is performed by placing the ink for aggregating the paint on the blanket 511 from the printing cylinder 529 in charge of the ink layer 51 in the second region R2. Can be performed.

  In addition, although the case where the seal | sticker S was stuck on the container 20 was demonstrated above, as shown in FIG. 10 (The figure which showed another form of the container 20), code images CD (image of a two-dimensional barcode etc.) An example) can be formed (printed or printed) on the outer peripheral surface of the container 20 by using an offset printer, an inkjet printer, or the like. In addition, a code image CD such as a two-dimensional bar code can be formed on and separately from this design of the container 20 on which the design including the identification mark 23 is formed on the outer peripheral surface. The code image CD can include information relating to the contents of the container 20 (for example, information relating to the volume, information relating to calories, and information indicating whether the beverage is an alcoholic beverage). Moreover, the information regarding the manufacturer of the container 20, a manufacturing place, a manufacturing date, etc. can be included.

  When the container 20 is manufactured, an image forming apparatus such as an offset printing machine or an ink jet printer is provided on the movement path of the container 20 by the conveying device 30 (to the side of the movement path) as described above. . Then, an image is formed on the container 20 from the side of the container 20 using the image forming apparatus (formation of the code image CD). As shown in FIG. 10, when the code image CD is formed below the identification mark 23 (when the code image CD facing the same direction as the direction of the identification mark 23 is formed), FIG. As shown in the drawing showing another example of the production line, the conveyance line of the container 20 is bent in a perpendicular direction. The image forming apparatus is installed at a location where the identification mark 23 is conveyed facing the front (location where the conveyance line is bent, a location indicated by a broken line in the figure), and the code image is formed below the identification mark 23. CD is formed.

  FIG. 12 is a diagram showing a state when the container 20 shown in FIG. 10 is displayed. When the container 20 shown in FIG. 10 is sold at a convenience store or the like, it is preferable that the code image CD faces forward as shown in FIG. In addition, it is preferable that the code 20 is sold with the code image CD facing the purchaser side of the container 20. In such a case, for example, it becomes easier to acquire information (information included in the code image CD) by the mobile phone H that the user has.

  By the way, in order to turn the code image CD forward, it is necessary to rotate the container 20 in the circumferential direction in a display device or the like installed in a convenience store or the like. Here, the container 20 is configured in the same manner as in FIG. 3 and the display device is configured as shown in FIG. 14 (a diagram showing the configuration of the display device), whereby the container 20 can be rotated in the circumferential direction. .

  If it demonstrates more concretely, the container 20 can be rotated in the circumferential direction by comprising the container 20 as shown in FIG. 13 (The figure which showed another one form of the container 20). Here, in the container 20 shown in FIG. 13, the first region R1 and the second region R2 are provided as described above. Further, the identification mark 23 is attached to the outer peripheral surface of the container 20 as described above. Further, a code image CD is formed below the identification mark 23. Here, the second region R2 and the code image CD are arranged in a state of being shifted by 90 ° in the circumferential direction of the container 20.

  On the other hand, the display device 700 shown in FIG. 14 has the same configuration as the transfer device 30 shown in FIG. 5 except that the stop plate 34 is provided. That is, the display device 700 includes a placement unit 31 that has a container placement surface 31A and moves the container 20, and a guide 32 that guides the movement of the container 20. The container placement surface 31A is provided with an inclination in the width direction and the front-rear direction, as described above. In addition, the display device 700 includes a first roller row 311 having a rotatable roll member 314 and a second roller row 312 to which the roll member 314 is fixed. In addition, the display device 700 includes a resistance imparting portion 33 that imparts sliding resistance to the outer peripheral surface of the container 20 in contact with the left guide 32. Similarly to the above, the resistance applying portion 33 is composed of a base material (not shown in the figure) and a sticking member 33B attached to the outer surface of the base material.

Next, the operation of the container 20 in the display device 700 will be described.
FIG. 15 is a view for explaining the operation of the container 20 in the display device 700. In the drawing, the first roller row 311 and the second roller row 312 (see FIG. 14) are not shown. Further, in this figure, the identification mark 23 (see FIG. 13) is not shown.

  As indicated by reference numeral 15A in FIG. 15, the container 20 placed behind the placement unit 31 is provided with an inclination in the left-right direction (width direction) and an inclination in the front-rear direction with respect to the container placement surface 31A. Then, it moves forward while being guided by the left guide 32. At this time, if the first region R1 is in contact with the resistance applying portion 33, slippage between the first region R1 and the resistance applying portion 33 is suppressed (a drag is applied to the first region R1), The container 20 moves forward while rotating clockwise (see reference numeral 15B). When the second region R2 comes into contact with the resistance applying portion 33 as indicated by reference numeral 15C, a slip occurs between the second region R2 and the resistance applying portion 33, and the rotation of the container 20 is stopped.

  Thereafter, the container 20 moves forward while being guided by the resistance applying portion 33. Thus, when the container 20 reaches the front of the display device 700, the code image CD is directed forward. In addition, in the present embodiment, the second region R2 and the code image CD are arranged with a predetermined positional relationship determined in advance. Specifically, when the second region R2 is directed to the left side (one direction), the code image CD is directed to the front (a direction intersecting one direction, a direction orthogonal to the one direction). The region R2 and the code image CD are arranged. For this reason, when 2nd area | region R2 will be in the state which contacted the resistance provision part 33, code | cord | chord image CD will face front (traveling direction).

  In the above description, the case where the code image CD is formed has been described as an example. However, as shown in FIG. 16 (a diagram showing another embodiment of the container 20), information such as the date of manufacture is directly printed. It may be. Moreover, as shown in FIG. 17 (the figure which showed another form of the container 20), the seal | sticker S can also be stuck with respect to the outer peripheral surface of the container 20 comprised not only as a can but as a plastic bottle. In the production line of the container 20 shown in FIG. 17, the first region R1 and the second region R2 described above can be used in the case of a cylindrical plastic bottle, but in the case of a plastic bottle, the container 20 is formed in the container 20. The container 20 can be rotated using a plurality of surfaces. There are other methods for rotating the container 20. This other method will be described later.

Hereinafter, the details of the container 20 shown in FIG. 17 will be described.
18 and 19 are views for explaining the details of the container 20. 18A shows a front view of the container 20, and FIG. 18B shows a left side view of the container 20. FIG. FIG. 19A shows a rear view of the container 20, and FIG. 19B shows a right side view of the container 20. 18A, 18B, 19A, and 19B are cross-sectional views taken along line AA.

  The container 20 in this embodiment has illustrated the container formed with resin materials, such as PET (polyethylene terephthalate). For example, such a container 20 can be manufactured by an injection molding (blow molding) method using a resin material or a blow molding method after forming a preform using a resin material. As shown in FIG. 18 (A), the container 20 in the present embodiment has a container body 21 having an opening (a drinking mouth) in the upper part and formed in a cylindrical shape and filled with a beverage therein, and an opening of the container body 21 And a cap 22 for closing the cover. A film F is attached to the outer peripheral surface of the container body 21.

  Here, an identification mark 23 is printed on the film F as shown in FIG. In addition, the container 20 includes a first protrusion 24 that protrudes in an annular shape in the radial direction of the container main body 21 from the outer peripheral surface of the container main body 21 at the upper part of the container main body 21 (under the cap 22). Here, the first protrusion 24 is formed integrally with the container body 21. Further, the container 20 includes a second protrusion 25 at a lower portion of the first protrusion 24. Here, the protruding amount of the second protruding portion 25 is smaller than the protruding amount of the first protruding portion 24. In this case, compared to the case where the second protrusion 25 protrudes from the first protrusion 24, the user's fingers when operating the cap 22 are less likely to be caught by the second protrusion 25.

  Further, as shown in the sectional view of FIG. 18A, the second protrusion 25 is wound around the container body 21 from the side where the identification mark 23 is provided to the side opposite to the side where the identification mark 23 is provided. It is provided to attach. In other words, it is provided along the clockwise direction from the side where the identification mark 23 is provided to the opposite side. More specifically, the second protrusion 25 is provided within a predetermined range in the circumferential direction of the container body 21.

  More specifically, when the container 20 is viewed from the side where the identification mark 23 is provided (see FIG. 18A), the second protrusion 25 is provided on the right side of the container 20. It has no configuration. In addition, at the position in the height direction at which the second protrusion 25 is provided, the right side of the container 20 (the region adjacent to the second protrusion 25) is in a state where the container body 21 is exposed. Yes. More specifically, it is a tangent line to the right side surface of the container body 21 and a tangent line from the front side to the back side of the container 20 and passing through the height position where the second protrusion 25 is provided (of FIG. 18A). The second protrusion 25 is not provided on the right side of the container 20 from the cross-sectional view).

  Moreover, the lower surface of the 2nd protrusion part 25 is formed in step shape, and it is a structure provided with several step part. If it demonstrates in detail, the lower surface of the 2nd protrusion part 25 is formed in the step shape so that height may reduce as it goes clockwise. For this reason, the 2nd protrusion part 25 in this embodiment is the structure provided with the 1st flat surface 251-the 6th flat surface 256 from which the position in a height direction differs in the lower part. In addition, the second projecting portion 25 has a plurality of end faces whose positions in the height direction are different from each other and whose positions in the circumferential direction of the container body 21 are different from each other.

  Here, each of the first flat surface 251 to the sixth flat surface 256 is arranged in a relationship (substantially orthogonal relationship) intersecting the outer peripheral surface of the container body 21 as shown in FIG. Yes. The first flat surface 251 is located on the side where the identification mark 23 is provided, as shown in FIG. Further, as shown in FIG. 18A, the sixth flat surface 256 is located on the side opposite to the side on which the identification mark 23 is provided. In addition, the second flat surface 252 to the fifth flat surface 255 are directed from the first flat surface 251 toward the sixth flat surface 256, the second flat surface 252, the third flat surface 253, the fourth flat surface 254, and the fifth flat surface 255. The flat surfaces 255 are provided in this order. Further, in the circumferential direction of the container 20, the first flat surface 251 to the sixth flat surface 256 are provided at predetermined angles. In addition, the first flat surface 251 is located at the bottom and the sixth flat surface 256 is located at the top.

Next, the structure of the conveyance apparatus 30 (refer FIG. 4) installed in a production line is demonstrated.
FIG. 20 shows a top view and a side view of the transfer device 30. Specifically, FIG. 4A shows a top view, and FIG. 4B shows a right side view. In addition, about the function similar to embodiment described above, the same code | symbol is used and the description is abbreviate | omitted here.

  In the transport device 30, as shown in FIG. 20A, a plurality of roll-shaped members 811 are provided on the placement unit 31. More specifically, a first roller row 812 in which a plurality of roll-shaped members 811 are arranged in the front-rear direction, and a second roller row 813 in which the plurality of roll-like members 811 are also arranged in the front-rear direction. , Provided on the mounting portion 31. Each roll-shaped member 811 is provided so as to be able to rotate along the movement path of the container 20 and smoothly moves the container 20 forward. In the transport device 30, a tilt in the front-rear direction is given to the placement unit 31, but a tilt in the left-right direction is not given.

  Further, the transport device 30 includes a rotation mechanism 600 that rotates the container 20 and directs the identification mark 23 attached to the container 20 forward. Here, as shown in FIG. 20A, the rotation mechanism 600 is attached to the rod-shaped member 61 and the rod-shaped member 61 provided along the movement path of the container 20 and above the placement portion 31. A first pin 521 to a sixth pin 526 projecting on the movement path of the container 20 are provided. Here, in the present embodiment, the first pin 521 is disposed on the most upstream side in the movement direction of the container 20, and the sixth pin 526 is disposed on the most downstream side in the movement direction. In addition, each of the first pin 521 to the sixth pin 526 is arranged with a certain gap. The rotation mechanism 600 includes a fixing member 53 that fixes the rod-shaped member 61 to the right guide 32.

  Moreover, as shown to the same figure (B), the inclination which leaves | separates from the mounting part 31 is provided to the rod-shaped member 61 as it goes ahead. For this reason, in the present embodiment, the first pin 521 is disposed closest to the placement unit 31, and the sixth pin 526 is located at a position farthest from the placement unit 31. In other words, the positions of the first pin 521 to the sixth pin 526 are shifted from each other in the height direction. In this figure, for easy understanding, the inclination of the rod-shaped member 61 is shown larger than the actual inclination.

Next, operation | movement of the container 20 in the conveying apparatus 30 is demonstrated.
FIG. 21 is a diagram for explaining the operation of the container 20 in the transport device 30. In the drawing, the first roller row 812, the second roller row 813, and the fixing member 53 are not shown.

  As shown by reference numeral 21 </ b> A in the drawing, when the container 20 is inserted into the transport device 30 with the identification mark 23 facing diagonally forward to the right, the first flat surface 251 comes into contact with the first pin 521. . As a result, a rotational force is applied to the container 20 and the container 20 rotates counterclockwise. Next, as the container 20 moves forward, the second flat surface 252 abuts against the second pin 522 (see reference numeral 21B), and the container 20 similarly rotates counterclockwise.

  After that, the container 20 has a circumferential direction in which the third flat surface 253 hits the third pin 523, the fourth flat surface 254 hits the fourth pin 524, and the fifth flat surface 255 hits the fifth pin 525. Rotate sequentially. Finally, the sixth flat surface 256 abuts against the sixth pin 526 (see reference numeral 21C), so that the identification mark 23 faces forward. Thereafter, the container 20 slides on the placement unit 31 and reaches the sticking device 70 (see FIG. 4). In the same manner as described above, the sticker S is attached by the attaching device 70.

  In the present embodiment, the identification mark 23 and the region provided with the second protrusion 25 (the first flat surface 251 to the sixth flat surface 256) are arranged with a predetermined positional relationship. The area where the identification mark 23 and the second projecting portion 25 are not provided is also arranged with a predetermined positional relationship. Specifically, when the identification mark 23 is oriented in one direction, the region where the second projecting portion 25 is not provided is oriented in a direction orthogonal to the one direction.

  For this reason, in the present embodiment, the container 20 rotates when the identification mark 23 faces in a direction other than the front, and the container 20 does not rotate when the identification mark 23 faces the front. In addition, even if the container 20 is loaded while the identification mark 23 is not directed forward, the identification mark 23 is directed forward in the process of moving the container 20.

  In addition, although the said description was abbreviate | omitted, the position in the height direction of each of the 1st pin 521-the 6th pin 526 is adjusted beforehand. That is, the third pin 523 and the third flat surface 253 are abutted so that the second pin 522 and the second flat surface 252 are abutted so that the first pin 521 and the first flat surface 251 are abutted. The positions of the first pin 521 to the third pin 523 are adjusted in advance in the height direction. Further, the sixth pin 526 and the sixth flat surface 256 are abutted so that the fifth pin 525 and the fifth flat surface 255 are abutted so that the fourth pin 524 and the fourth flat surface 254 are abutted. The positions of the fourth pin 524 to the sixth pin 526 are adjusted in advance in the height direction.

Next, another example of the operation of the container 20 will be described.
22 and 23 are diagrams showing another operation example of the container 20.
As shown in FIG. 22A, when the container 20 is loaded with the identification mark 23 facing the rear side of the transport device 30, the third flat surface 253 is facing the front of the transport device 30. . The container 20 moves forward, but the third flat surface 253 passes above the first pin 521 and the second pin 522 (see also FIG. 20B). For this reason, the container 20 reaches the third pin 523 without rotating. The container 20 receives rotational force from the third pin 523 and rotates in the same manner as described above. Then, the container 20 moves forward with the identification mark 23 facing forward, as described above.

  Further, for example, as shown in FIG. 22B, when the container 20 is introduced with the identification mark 23 facing diagonally left front, the sixth flat surface 256 faces the front of the transfer device 30. The container 20 moves forward, but the sixth flat surface 256 passes over the first pin 521 to the fifth pin 525 (see also FIG. 20B). For this reason, the container 20 reaches the sixth pin 526 without rotating. The container 20 receives a rotational force from the sixth pin 526 and rotates in the same manner as described above. Then, the container 20 moves forward with the identification mark 23 facing forward, as described above.

  Further, for example, as shown in FIG. 23, the container 20 may be loaded with the identification mark 23 facing forward. In this case, the second projecting portion 25 does not exist on the side surface of the container 20 that faces the side where the first pin 521 to the sixth pin 526 are disposed. In other words, the region (surface) where the second projecting portion 25 does not exist and the side where the first pin 521 to the sixth pin 526 are arranged face each other. In other words, the first flat surface 251 to the sixth flat surface 256 that abut against the first pin 521 to the sixth pin 526 are not positioned on the right side surface side of the container 20 in the drawing. For this reason, the container 20 moves the conveyance apparatus 30 without rotating. That is, the identification mark 23 moves to the pasting device 70 while maintaining the state of facing forward.

In the above description, the first flat surface 251 to the sixth flat surface 256 are formed using the stepped portion formed in the second protruding portion 25, but the rib-shaped protrusion protruding from the outer peripheral surface of the container main body 21. By providing a plurality around the container body 21, surfaces corresponding to the first flat surface 251 to the sixth flat surface 256 can be formed. Moreover, the surface equivalent to the 1st flat surface 251-the 6th flat surface 256 can also be formed by forming the some protrusion which protrudes in the downward direction from the 1st protrusion part 24, and differs in the protrusion amount. Moreover, in the said embodiment, although the container 20 was moved using the inclination of the mounting part 31, a container is driven by this roll-shaped member which drives and drives the roll-shaped member provided in the mounting part 31 with a motor etc. Twenty movements can also be performed.
Other methods described above include, for example, a method in which the first projecting portion 24 is formed into an oval shape and dropped from the suspension fitting (Japanese Patent Application No. 2009-289401), and the second projecting portion 25 as shown in FIG. Method (Japanese Patent Application No. 2009-1000051), a method in which the first projecting portion 24 is lifted with a guide, and the support from the guide is released at a face-cut portion provided in the first projecting portion 24 (Japanese Patent Application No. 2009- 131377).
