Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a dummy body for an automatic vending machine and its mounting structure for unmanned sale of juice, coffee, beer, etc., in canned or bottled beverages, or cigarettes, dry batteries, and the like.

[0002]

[Prior art]

 For example, in vending machines for canned beverages, a cylindrical dummy is displayed on the front of the vending machine, instead of the actual product for sale.

FIG. 6 shows the dummy body 2 of the vending machine 1 and its mounting mechanism (see Japanese Utility Model Publication No. 4-9663). In FIG. 6, the dummy body 2 comprises a cylindrical body portion 3 having an upper opening 3a and a lower opening 3b, an upper lid 4 and a cylindrical fitting member 5 fixed to the lower end of the body portion 3. . The dummy body 2 is mounted via a fitting member 5 in a mounting hole 7 opened in a stage 6 such as an iron plate. An irradiation light source K such as a fluorescent lamp is arranged below the stage 6. There is.

On the lower end surface of the fitting member 5, a short cylindrical insertion / extraction cylinder 5 a is integrally provided. The insertion / extraction cylinder 5a is provided with a pair of stopper pieces 5b, 5b projecting outward on the outer peripheral edge of the tip, and a pair of leaf spring-like elastic moderating pieces on the body of the insertion / extraction cylinder 5a. 5c and 5c are formed on the same circumference. Each moderation piece 5c is integrally formed with a moderation projection 5d on its outer side surface.

On the other hand, the mounting hole 7 opened in the stage 6 is formed into a circular shape as a whole so that the insertion / extraction cylinder 5a fits into each other, and is fixed at a position corresponding to the stopper pieces 5b, 5b of the insertion / extraction cylinder 5a. It has notches 7a and 7a for inserting and removing the female pieces, and also has notches 7b and 7b for inserting protrusions for moderation and recesses 7c and 7c for moderation adjacent to these.

A step portion 5e is formed on the upper end surface of the fitting member 5 so that the lower opening 3b of the body portion 3 is fitted to the step portion 5e. A plurality of locking claws 5f that are locked in the claw insertion grooves 3c formed on the peripheral surface are formed. That is, the fitting member 5 is configured to be fixed to the lower end of the body portion 3.

The fitting member 5 is formed by injection molding of an opaque white synthetic resin material (for blocking the illumination light from the illumination light source K) having heat resistance and weather resistance, such as polycarbonate. The body portion 3 is formed by injection molding of a transparent, colorless synthetic resin material having heat resistance and weather resistance.

When the fitting member 5 is fixed to the stage 6, after the fitting member 5 is engaged with the lower end of the body portion 3, the stopper piece of the fitting member 5 is inserted into the insertion / removal notches 7 a and 7 a of the mounting hole 7. The insertion / extraction cylinder 5a is inserted into the mounting hole 7 with the 5b aligned. At this time, the stopper piece 5b is inserted into the back surface side of the stage 6, and the moderation convex portion 5d is fitted into the notches 7b and 7b. After that, when the fitting member 5 is swung, the stopper 5b moves to the position on the back surface side of the stage 6 that is out of the notch 7a, making it impossible to remove the fitting member 5 and at the same time, the moderation protrusion 5d of the insertion / extraction cylinder 5a. Are fitted into the adjacent moderation recesses 7c, 7c from the notches 7b, 7b to prevent the fitting member 5 from rotating.

[0009]

[Problems to be solved by the device]

 However, according to the above configuration, although the fitting member 5 can be securely fixed to the stage 6, not only the fitting member 5 but also the body portion 3 need to be formed by injection molding which is higher in cost than blow molding. There is. The problem is that the shapes of the stop pieces 5b, 5b, the moderation pieces 5c, 5c, the moderation projections 5d, 5d, the locking claws 5f, etc. for securely preventing the dummy body 2 from being pulled out and preventing rotation are complicated. And comes from the need for precision. In addition, there is a problem in workability such that the manufacturer needs to perform an assembly work for fixing the body portion 3 to the fitting member 5 before the dummy body 2 is packed.

The present invention has been made in consideration of the above points, and an object of the present invention is to securely fix the dummy body to the stage, to reduce the cost and to stabilize the workability. To provide a good dummy for a vending machine and its mounting structure.

[0011]

[Means for Solving the Problems]

 In order to achieve the above object, the dummy body of the present invention has a short cylindrical flange having a small diameter integrally projecting downward from the lower part of its body, and the short cylindrical flange has an outer circumference of at least 3 mm. It forms the male thread of the thread. Therefore, since the mounting structure of the dummy body on the stage for product display can be extremely simplified, the body part used in the present invention can be integrally formed by blow molding which is cheaper than injection molding. Further, by fixing the dummy body by screwing, it is possible to securely fix the dummy body without applying excessive force when installing the dummy body. Further, since the dummy body is fixed by at least three screw parts, its stability can be increased.

Further, when the body is formed by blow molding of a semi-transparent or transparent colorless or colored synthetic resin material having heat resistance and weather resistance such as polycarbonate, heat such as lighting is applied to the stage. It is possible to prevent deformation of the dummy body directly connected to this even if it is transmitted to.

The stage mounting hole for mounting the dummy body can be easily fixed by providing at least three notch portions in a portion corresponding to the male screw portion, and the dummy body can be fixed to the stage. In addition to being able to perform more reliably, it is possible to easily form the cutout portion with respect to the mounting hole of the stage.

Further, in the case where a convex portion is provided on the outer periphery of the short cylindrical flange to abut the end of the cutout portion to prevent the screw body from rotating in a fixed position, the convex portion is provided. By screwing the dummy body in until it touches the notch, the dummy body can be faced directly in front of the dummy body, which facilitates the installation work of the dummy body and improves the appearance of the dummy body after installation. .

In addition, in the case where a notch is formed in the mounting hole and a protrusion is formed on the outer periphery of the short cylindrical flange to engage with the notch and suppress the rotation of the dummy body at a fixed position, Since the screwing operation of the dummy body is suppressed when the dummy body is in front of the dummy body, it is easy to orient the dummy body directly in front of the dummy body, and the dummy body can be prevented from coming off.

[0016]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a vending machine 1. 1a is a front door that can be opened and closed to replenish products, and an exhibition for displaying a plurality of cylindrical dummy bodies (small can type, thick can type, bottle type) 2 on top of it. Chambers 1b are provided in upper and lower two stages, and push buttons 1c for product selection are arranged in association with the dummy bodies 2. A product outlet 1d is provided on the lower side of the front door 1a, and a cash inlet 1e, a change outlet 1f, and an operation lever 1g for returning money are provided at the central portion on the right side of the front door 1a. There is.

A commercially available stage (for example, an iron plate) 6 serving as a mounting surface of the dummy body 2 is provided inside the exhibition room 1b, and a mounting hole 7 is formed in the stage 6 at the mounting position of the dummy body 2. Has been done. An illumination light source K for illuminating the dummy body 2 from below is arranged on the back side of the stage 6.

2 to 4 show a preferred first embodiment of the dummy body (thick can type) 2 of the present invention. In these drawings, the members designated by the same reference numerals as those in FIG. 6 are the same or equivalent members, and thus detailed description thereof will be omitted. The dummy body 2 is integrally formed by blow molding of a transparent colorless synthetic resin material having heat resistance and weather resistance such as polycarbonate for the body 3 having the upper opening 3a and the lower opening 3b and the short cylindrical flange 8. The dummy body main body 2a is held, and the upper lid 4 attached to the upper portion of the dummy body main body 2a.

A film-shaped or sheet-shaped product display label (hereinafter referred to as a label) 9 for displaying a product to be sold is attached to and held on the surface of the body 3 on the front side of the dummy body 2. There is. The label 9 is, for example, a plastic film or sheet, and is printed to form a display body corresponding to a real semicircular portion. A label holding member for forming a slit S for sandwiching the label 9 in the body portion 3 by inserting both end portions 9a of the label 9 into the back surface side of the dummy body 2 and the body portion 3. 10 is attached.

A large number of wart-shaped protrusions 10a are formed on the surface of the body 3 with which the label holding member 10 abuts, and the label 9 can be more effectively held by the protrusions 10a. . Since the label holding member 10 does not come into direct contact with the high temperature stage 6, it can be formed using a resin such as polypropylene or polyethylene terephthalate.

A ring member 13 having an outer diameter larger than the outer diameter of the body portion 3 is fitted in a lower portion of the body portion 3 of the dummy body 2a, and the ring member 13 is displaced by the ring member 13. In addition, the light for illumination is prevented from leaking from the connecting portion of the dummy body 2 to the mounting hole 7.

As shown in the enlarged view of FIG. 3, the ring member 13 is attached to the dummy body 2a by forming a small-diameter portion 13a formed on the inner diameter of the ring member 13 on the lower end of the body portion 3 of the dummy body 2a. It is carried out by engaging the ring engaging portion 3d thus formed. The ring member 13 is formed by injection molding of a semitransparent white synthetic resin material having heat resistance and weather resistance such as polycarbonate.

The short tubular flange 8 integrally formed on the lower portion of the body portion 3 of the dummy body 2 a has a cylindrical shape with a smaller diameter than the body portion 3. Since three male screw portions 11 are formed on the outer periphery of the flange 8 by projection, three notch portions 12 are formed in the mounting hole 7 of the stage 6 at positions corresponding to the male screw portions 11. ing.

Hereinafter, the configuration of each male screw portion 11 and the notch portion 12 will be described in detail mainly with reference to FIG. FIG. 4 is a plan view in which the portion of the short cylindrical flange 8 is cut along a plane flush with the stage 6 and the stage 6 is seen through. As shown in FIG. 4, each of the male screw portions 11 forms a three-thread screw (male screw portion 11) having a different shape. In the following description, in order to distinguish them, they are referred to as male screw portions 11a, 11b, 11c. Similarly, the notch 12 is also referred to as notch portions 12a, 12b, 12c to distinguish between the male screw portion 11 and the notch portion 12.

First, the male screw portions 11a and 11c have one corner cut. This is because at the stage of blow molding the dummy body 2a, an outer frame that can be divided into two on the line AA shown in the figure is used as a mold, and this outer frame can be easily removed. . Therefore, by changing the shape of the mold and the method of forming the dummy body 2a, the male screw portions 11 may all have the same shape.

On the other hand, the shape of the cutout portion 12b is different from the shape of the other cutout portions 12a and 12c. That is, while both ends of the other cutout portions 12a and 12c are cut in a rectangular shape, the cutout portion 12b is continuously cut at the end portion near the cutout portion 12c. . (Hereinafter, this portion will be referred to as a continuous cutting portion 12d.) This means that after inserting the protrusion 14 provided directly above the male screw portion 11b into the mounting hole 7 from the notch portion 12b side, the dummy body 2 is removed. When it is screwed (clockwise), the protrusion 14 formed on the short cylindrical flange 8 is gradually elastically deformed inward by the continuous cutting portion 12d, and the cutout portion 12b and the cutout portion 12d are formed. This is to enable the engagement with the inside of the notch 15 provided between 12c and 12c.

A convex portion 16 is provided on the short cylindrical flange 8 between the male screw portion 11b and the male screw portion 11c. The convex portion 16 is inserted into the cutout portion 12c and abuts on the end portion of the cutout portion 12c closer to the cutout portion 12a, whereby the screw-in rotation of the short cylindrical flange 8 is fixed. You can block it in position.

That is, when the dummy body 2 having the above-described configuration is mounted on the stage 6, the short cylindrical flange 8 with the external thread portions 11a, 11b, 11c corresponding to the cutout portions 12a, 12b, 12c, respectively. It is only necessary to rotate the dummy body 2 in the clockwise direction after inserting the dummy body 2 into the mounting hole 7. At this time, the convex portion 16 abuts on the end of the cutout portion 12c to prevent the screwing rotation at a fixed position, and the protrusion 14 engages with the inside of the notch 15 to facilitate the screwing. I am trying not to be released. As a result, not only the work of mounting the dummy body 2 on the stage 6 becomes extremely easy, but also the dummy body 2 can be securely fixed at a position where it is always directly in front.

Further, in the mounting structure of the dummy body for the vending machine of the present invention, since the dummy body 2 is fixed by screwing the male screw portion 11, the male screw portion 11 is made larger than the fixing by the fitting engagement. Eliminates the need for elastic deformation. Therefore, the male portion 11 can be made to protrude further, the dummy body 2 can be securely fixed, and there is no tendency for damage due to deformation of the engaging piece (the male screw portion 11 in this example). Since the molding does not require so much precision, there is no need to perform injection molding, and blow molding at low cost can be sufficient for manufacturing.

Furthermore, since the outer peripheral surface of the short cylindrical flange 8 is not formed with a substantially annular single male thread, but is formed with three male thread portions 11, the width of the short cylindrical flange 8 can be extended. On the other hand, the portion corresponding to the female screw can be formed by notching the notched portion 12 in the thin iron plate of the stage 6. In addition, the manufacturing cost can be suppressed as much as possible, and the configurations of the mounting hole 7 and the short cylindrical flange 8 are further simplified.

In the above example, the mounting hole 7 formed in the stage 6 has a special shape that matches the short cylindrical flange 8 and the male threaded portion 11, so that the male threaded portion 11 can be reliably held. Although the example of engaging is shown, the present invention is not limited to this. That is, the mounting hole 7 formed in the stage 6 may have a conventional shape, and the male screw portion 11 may be formed at an appropriate position on the short cylindrical flange 8 so that the mounting hole 7 can be engaged with the mounting hole 7. .

Further, by providing the ring member 13, light is prevented from leaking from between the mounting hole 7 and the dummy body 2a, and the label 9 is prevented from being displaced. The ring member 13 may be omitted if the deviation does not pose a problem or if there is no gap between the mounting hole 7 and the dummy body 2a. In this case, it is possible to omit the steps of injection-molding the ring member 13 and fitting the ring member 13 into the dummy body 2a, thereby further reducing the cost. When the ring member 13 is omitted in this way, a flange for preventing the displacement of the label 9 may be integrally formed on the lower end portion of the body portion 3.

In the above preferred embodiment, the thick can type dummy body 2 has been described. However, the dummy body 2 is not limited to the thick can type, but can be a thin can type or a bottle type dummy body 2 described later. It goes without saying that it can also be applied to. Further, by making the size and shape of the mounting hole 7 common regardless of the thick can type, the thin can type, and the bottle type, the contents of the vending machine 1 can be changed regardless of the type. It is possible to easily replace the dummy body 2.

FIG. 5 shows a dummy body 2 which is another embodiment of the present invention. In this figure, the members denoted by the same reference numerals as those in FIGS. 1 to 4 are the same or equivalent members, and therefore detailed description thereof will be omitted. The dummy body 2a has a bottle type shape and is formed by, for example, blow molding of transparent polycarbonate. Then, as shown in the figure, a colored portion 2b colored in the color of the drinking water, which is the content, and a non-colored portion 2c for sticking the label 9 are formed on a part of the dummy body 2a. There is.

Further, a mark 17 is projected on the back surface of the dummy body 2a at a position right behind. Therefore, the operator can surely recognize the rotating state of the dummy body 2 by the mark 17, and the short cylindrical flange 8 of the dummy body 2 is inserted into the mounting hole 7 so that the mark 17 is aligned with the cutout portion 12b. , By rotating this clockwise, it can be surely set to a fixed position.

Further, since the above-described example shows the case where the dummy body 2 in the shape of a bottle which is thinner than the dummy body 2 of the thin can type is formed, the short cylindrical flange 8 of the dummy body 2 is By increasing the diameter of the short cylindrical flange 8 of the thick can type and thin can type dummy bodies 2 to be larger than the diameter, the thick can type and thin can type dummy bodies can be more securely fixed and the mounting hole 7 The amount of light radiated through the is increased. The diameters of the short cylindrical flanges 8 may be made uniform so that different dummy bodies can be set in the common mounting hole 7.

The ring member 13 and the body 2 used in each of the above-described embodiments are made of a synthetic resin material having heat resistance and weather resistance such as polycarbonate, and the ring member 13 is a semitransparent or opaque white or colored synthetic resin. The body portion 2 is made of a semi-transparent or transparent colorless or colored synthetic resin material. On the other hand, the label holding member 10 and the upper lid 4 are made of a translucent or transparent colorless or colored synthetic resin material such as polypropylene.

[Effect of the invention]

 As described above, according to the present invention, since the mounting structure of the dummy body on the stage for product display can be extremely simplified, it is possible to integrally form the body part by blow molding which is cheaper than injection molding. is there. Also, since the dummy body is fixed by screwing, it can be securely fixed without applying excessive force when installing the dummy body. Further, since the male screw portion has at least three threads, the stability is improved, the rotation angle for mounting is smaller than that of the single thread screw, and the configuration is simple. The flange can be shortened, and the raw material of the dummy body can be reduced as much as possible.

When the body is formed by blow molding of a semi-transparent or transparent colorless or colored synthetic resin material having heat resistance and weather resistance such as polycarbonate, a dummy body is formed even if heat is transferred to the stage. Can be prevented from deformation.

Since the mounting hole of the stage for mounting the dummy body is provided with at least three cutout portions in a portion corresponding to the male screw portion, the dummy body can be easily fixed, and the dummy body can be fixed to the stage. The dummy body can be more securely fixed, and the notch portion can be easily formed in the mounting hole of the stage.

Further, in the case where a protrusion is provided on the outer periphery of the short cylindrical flange to abut the end of the cutout portion to prevent the screw body from rotating in a fixed position, the protrusion is provided. By screwing the dummy body until the abutment contacts the notch, the dummy body can be made to face straight ahead. In addition, when a notch is formed in the mounting hole and a protrusion is formed on the outer circumference of the short cylindrical flange to engage with the notch and suppress the rotation of the dummy body at a fixed position, the dummy body is Since the screwing operation of the dummy body is suppressed when the dummy body is in the front state, it is easy to orient the dummy body directly in front of the dummy body, and the dummy body can be prevented from coming off.
