Description

The present invention relates to a mounting structure for a cylindrical member for a cup-type vending machine for mounting a cylindrical member in an airtight state on one surface of a plate member having an opening so as to communicate with the opening.

  As a conventional attachment structure of this kind of cylindrical member, for example, one disclosed in Patent Document 1 is known. This Patent Document 1 relates to a cup beverage vending machine, and a canister that accommodates a powder raw material corresponds to a cylindrical member. Below the canister, a chute device is continuously provided via a plate material. An auger is provided in the lower part of the canister, and when the cup beverage is sold, a predetermined amount of powder material is supplied to the chute device by rotating the auger by a predetermined angle. A load cell type weighing scale is provided at the bottom of the canister. This weighing scale weighs the combined weight of the canister and the powder raw material contained therein. The amount of the powder raw material supplied at the time of sale is calculated by the difference between the weight measured at the time of sale standby and the weight measured at the time of sale. The canister and chute device are installed in a room that is kept airtight and maintained in a predetermined temperature range.

  Generally, a canister that contains a powder raw material needs to be kept airtight so that moisture does not enter. For example, if moisture enters through a gap between the canister and the chute device, the powder raw material may become damp and harden or deteriorate. In the above-described conventional vending machine, the entire chamber in which the canister and chute device are installed is kept in an airtight state, so there is no risk of deterioration of the powder raw material as described above, but the entire chamber is in an airtight state. Since the equipment for maintaining a large scale becomes large, the manufacturing cost of the vending machine increases.

  Alternatively, in order to ensure the airtight state of the canister, for example, when the canister is firmly pressed against the plate material through the packing and fixed, the reaction force from the plate material acts on the canister. The raw materials cannot be accurately measured. Furthermore, in this case, vibrations and shocks generated on the chute device side are transmitted to the canister, which may cause a problem such as spilling of the powder raw material held on the auger of the canister.

The present invention has been made in order to solve such problems, and a cup type that can be attached to a plate member in an airtight state with almost no reaction force from the plate member acting on the plate member. It aims at providing the attachment structure of the cylindrical member for vending machines .

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a canister 4 (cylindrical member) to which the present invention is applied, together with a base 20 to which the canister 4 is attached and a chute device 10 attached below the base 20. The canister 4 is provided in a cup-type vending machine that sells beverages such as coffee and cocoa, and a plurality of canisters 4 are arranged side by side on the base 20 (only one is shown in FIG. 1). , Cocoa, sugar and powdered milk, etc. When the beverage is sold, the necessary powder material is sent from each canister 4 to the chute device 10. The chute device 10 temporarily stores the powder raw material delivered from the canister 4 and discharges the stored powder raw material at the timing when the cup has moved directly below the powder raw material.

  The base 20 includes a mounting plate 21 that extends in the vertical direction and the left-right direction, and a horizontal plate 22 that protrudes forward from the upper end of the mounting plate 21. A plurality of circular openings 23 are formed in the horizontal plate 22 in a state of being arranged at equal intervals in the left-right direction. A plurality of holes 24 are formed in the mounting plate 21, and a pair of upper and lower locking tools having an elastic arm for mounting the chute device 10 in the vicinity of the hole 24 on the back surface of the mounting plate 21 ( Both are not shown).

  As shown in FIGS. 1 to 3, the canister 4 includes a canister main body 5 that accommodates the powder raw material and a delivery pipe 6 that delivers the powder raw material. The canister body 5 has a rectangular cross section elongated in the front-rear direction with respect to the lateral width. The size of the cross section is constant at the upper part and gradually decreases toward the center at the lower part. An auger (not shown) is horizontally provided at the bottom of the canister body 5. The auger is rotatably mounted with one end thereof facing the delivery pipe 6 and is rotated at a predetermined angle by driving a motor (not shown) at the time of beverage sales. Deliver powder raw material. The delivered powder raw material is supplied to the chute device 10 through the delivery pipe 6.

  At the lower end of the canister body 5, for example, a weigh scale (not shown) configured by a load cell is provided. This weight scale measures the combined weight of the canister 4 and the powder raw material accommodated therein. Based on the measurement result, the amount of the powder raw material in the canister 4 is estimated, and when the amount decreases, the powder raw material is replenished.

  The delivery pipe 6 of the canister 4 is made of a synthetic resin such as polypropylene and extends horizontally outward from the bottom of the canister body 5 and extends vertically downward from the tip of the canister 4 to the vicinity of the horizontal plate 22. Is located directly above the opening 23 of the horizontal plate 22. On the outer peripheral surface of the delivery pipe 6, a lower convex portion 6a is provided at the lower end, and an upper convex portion 6b is provided at an upper portion with a predetermined interval so as to be continuous in the circumferential direction.

  The mounting member 7 is made of an elastic material such as rubber (for example, silicon rubber), and includes a cylindrical main body portion 8 and a skirt portion 9 that extends outward from the main body portion 8. The main body 8 has a predetermined diameter so as to be fitted to the delivery pipe 6 from the outside. A concave portion 8 a is formed at an intermediate portion of the inner peripheral surface of the main body portion 8 so as to be continuous in the circumferential direction.

  With the above configuration, the mounting member 7 has a portion above the recess 8 a of the main body 8 that fits exactly to the lower portion of the delivery pipe 6 of the canister 4. In this state, the upper end of the main body portion 8 abuts on the upper convex portion 6b of the delivery pipe 6, whereby the mounting member 7 is positioned in the vertical direction, and the concave portion 8a of the mounting member 7 is the lower convex portion of the delivery pipe 6. By engaging with 6a, the mounting member 7 is prevented from coming off from the delivery pipe 6.

  The skirt portion 9 extends from the lower side to the outer side than the concave portion 8 a of the main body portion 8, extends toward the horizontal plate 22, and is provided so as to cover the outer peripheral surface of the main body portion 8. Specifically, the skirt portion 9 includes an inclined portion 9a extending obliquely downward and a leg portion 9b extending from the lower end to the horizontal plate 22, and protrudes outward from the lower end portion of the leg portion 9b. Are provided with ribs 9c.

  In the state in which the mounting member 7 is attached to the canister 4 as described above, the leg portion 9b of the skirt portion 9 is in contact with the upper surface of the horizontal plate 22 via the rib 9c, and the elasticity of the skirt portion 9 causes the horizontal plate 22 to be in contact. Is in close contact with the Further, the lower end portion of the main body portion 8 is inserted into the opening 23 of the horizontal plate 22.

  The chute device 10 includes a chute body 11, a shutter plate (not shown) that opens and closes an opening at the lower end of the chute body 11, a packing 12 attached to the upper end portion of the chute body 11, and the like. The chute body 11 is made of, for example, a translucent synthetic resin and is formed in a rectangular tube shape that extends in the vertical direction. In addition, a pair of upper and lower protrusions 13 (only the lower one is shown) are provided on the wall surface of the chute main body 11 on the side facing the mounting plate 21 so as to protrude at right angles to the outside. The pair of upper and lower protrusions 13 are respectively inserted into upper and lower holes 24 (only the lower one is shown) of the mounting plate 21 and are snap-engaged with the elastic arms of the pair of upper and lower locking members. The main body 11 is fixed to the mounting plate 21. In this state, the packing 12 is in close contact with the lower surface of the horizontal plate 22, thereby ensuring an airtight state between the chute device 10 and the horizontal plate 22.

  The shutter plate is rotatably supported by the chute main body 11 via the shaft portion, and is in contact with the lower end of the chute main body 11 while being biased by the spring 14 to close the opening. The shutter plate is opened and closed by an actuator (not shown) such as a solenoid.

  As described above, according to the present embodiment, the main body portion 8 of the mounting member 7 having elasticity is fitted to the delivery pipe 6 of the canister 4, and the skirt portion 9 that spreads outward from the main body portion 8 of the mounting member 7. However, since it is in close contact with the horizontal plate 22 due to its elasticity, the canister 4 can be attached to the horizontal plate 22 in an airtight state. As a result, moisture can be prevented from entering the canister 4, and therefore deterioration of the powder raw material accommodated in the canister 4 can be prevented.

  The skirt portion 9 of the mounting member 7 is composed of an inclined portion 9 a extending obliquely downward from the main body portion 8 and a leg portion 9 b extending vertically downward from the lower end thereof, and the leg portion 9 b is in close contact with the horizontal plate 22. The reaction force from the horizontal plate 22 can be absorbed mainly by the elastic deformation of the inclined portion 9a so that it hardly acts on the canister 4. As a result, the canister 4 and the powder raw material can be accurately measured by the weight meter, and therefore the powder raw material can be replenished at an appropriate timing before the powder raw material disappears in the canister 4.

  Even when vibration or impact occurs on the chute device 10 side, such vibration or impact is absorbed by the inclined portion 9 a of the skirt portion 9 and hardly transmitted to the canister 4. Therefore, for example, the powder raw material held in the auger of the canister 4 can be prevented from spilling into the chute body 11 due to vibrations or impacts generated when the chute device 10 is opened and closed.

  Since the main body portion 8 of the mounting member 7 is inserted into the opening of the horizontal plate 22, the communication state between the chute device 10 and the opening 23 of the horizontal plate 22 can be easily ensured. In this case, even if there is a gap between the main body 8 and the opening 23, the canister 4 can be kept in an airtight state by the skirt portion 9 that covers the outer peripheral surface of the main body 8.

  In addition, this invention can be implemented in various aspects, without being limited to embodiment described. For example, the embodiment is an example in which the present invention is applied to a canister 4 for delivering a powder raw material in a cup-type vending machine. However, the present invention is not limited thereto, and is in close contact with a plate material and communicated with an opening. It can apply widely to the cylindrical member attached so. Furthermore, in the embodiment, only one skirt portion 9 extending from the main body portion 8 of the mounting member 7 is provided. However, the skirt portions 9 may be provided twice, or legs extending vertically downward from the inclined portion 9a. You may provide the part 9b doubly. Thereby, the contact state of the canister 4 can be obtained more reliably.

It is a perspective view which shows the state which attached the canister by embodiment to the base. It is a fragmentary sectional view which follows the AA line of FIG. It is a half perspective view when a mounting member is divided vertically.
