Definitions
- This invention relates to an article storage device for a vending machine, and more particularly to an article storage device of this kind which stores a large number of articles in a manner placed one after another, and pushes out the articles one by one by means of a pusher to dispense them for vending.
- the present applicant proposed this kind of article storage device for a vending machine e.g. in Japanese Patent Application No. 9-69211.
- the article storage device 50 includes a plurality of article racks 51 arranged one above another, each of which is formed with a pair of right and left article passages 52. Article S are stored in these article passages 52.
- Each article rack 51 is mounted in a body of the vending machine, not shown, such that it can be moved in a front-rear direction by means of rollers 53, ball bearings 54, etc. and that it can be drawn out of the machine body.
- the article rack 51 has a rack opening/closing plate 55 mounted at a front end thereof for opening/closing the article passage 52, and a pair of pushers 56 each movably mounted behind the rack opening/closing plate 55 in a manner corresponding to the respective article passages 52.
- a large number of articles S are stored in the article passages 52 in a manner placed one after another between the rack opening/closing plate 55 and each of the pushers 56.
- the pushers 56 are each slidably mounted on a guide rod 57 arranged in a front-rear direction under an upper article rack 51. While the pusher 56 can slide forward and backward along the guide rod 57, it is always urged forward by helical tension springs 59 connected thereto by a wire 58, etc.
- each pusher 56 is supported by a corresponding guide rod 57 in a manner hung therefrom, and hence the pusher 56 is in brought into contact with the rearmost article S at a lower point than a supporting point at which the pusher 56 is supported by the guide rod 57. Therefore, moment which acts on a lower portion of the pusher 56 to turn the pusher 56 backward about the supporting point is produced by a reaction force from the rearmost article S generated when the pusher 56 pushes the articles S forward, and by an urging force applied via the articles S to the pusher 56 when the article rack 51 is pushed back after being replenished. This causes the pusher 56 to be inclined with respect to the guide rod 57, whereby sliding (frictional) resistance to the movement of the pusher 56 on the guide rod 57 is increased.
- the pusher 56 pushes relatively light articles S, the sliding resistance is not significant so that no serious problem occurs.
- the sliding resistance between the pusher 56 and the guide rod 57 is much increased, causing a large loss of the urging force of the pusher 56.
- the urging force of the helical tension springs 59 is increased, it causes an increase in resistance produced when the article rack 51 is pushed back into the machine body after being replenished with articles S. This seriously affects ease of handling of the article rack 51.
- the urging force of the articles S acts on the pusher 56 to increase the inclination of the pusher 56 with respect to the guide rod 57.
- the sliding resistance between the pusher 56 and the guide rod 57 is increased, causing a large loss of operating force and hence also affecting the ease of handling of the article rack 51.
- the guide rod 57 is very thin and long, and cannot avoid sagging to some degree, which also causes an increase in the sliding resistance of the pusher 56 on the rod 57.
- the present invention provides an article storage device for a vending machine, including an article rack provided within a body of the vending machine in a manner such that the article rack can be moved in a front-rear direction and drawn forward out of the body of the vending machine, the article rack having an article passage formed therein for receiving a large number of articles one behind another, a rack opening/closing member provided at a front end of the article rack, for opening a dispensing opening of the article passage during a vending operation, and closing the dispensing opening except during the vending operation, a pusher inserted in the article passage, for pushing forward the articles received in the article passage, a guide member arranged above the article rack in a manner such that the guide member extends in the front-rear direction, for guiding the pusher in the front-rear direction, and urging means for urging the pusher forward.
- the article storage device is characterized in that the guide member comprises a body plate extending vertically, and a guide portion integrally formed with the body plate, the guide portion having a pair of guide protrusions laterally spaced from the body plate and being vertically opposed to each other, and the pusher comprises a pusher body inserted into the article passage, and a pair of front and rear rollers each formed with a U-shaped groove and attached to an upper side of the pusher body in a manner rotatable about respective horizontal axes, the pusher being mounted between the vertically opposed guide protrusions of the guide portion of the guide member, with the U-shaped groove of each of the rollers being fitted on the vertically opposed guide protrusions.
- this article storage device for a vending machine
- the article rack when the article rack is to be replenished with articles, it is drawn forward out of the machine body, and then the articles are placed one behind another in the article passage in a state of the pusher being held within the machine body.
- the article rack After the replenishment, the article rack is pushed back into the machine body, whereby a rearmost one of the articles placed in the article passage pushes the pusher back to its extreme backward position.
- the numerous articles are made ready for vending in a state sandwiched between the rack opening/closing member in its closed position and the pusher body of the pusher urged forward by the urging means.
- the rack opening/closing member opens the dispensing opening of the article passage, whereby a foremost one of the articles placed in the article passage is dispensed from the article rack.
- the pusher moves backward along the guide member after replenishment of articles, with the pusher body thereof being pushed by the articles in the article passage, while it moves forward along the guide member during a vending operation, with the pusher body pushing the articles.
- the pair of front and rear rollers mounted on the pusher body roll on the guide member, so that moment produced by a pushing force applied between the pusher body and the articles to act on the pusher body is absorbed by the rollers, whereby frictional resistance to the movement of the pusher on the guide member is considerably reduced.
- the urging force of the urging means required for moving the pusher forward can be reduced, which makes it possible to enhance ease of handling of the article rack after replenishment of articles.
- each of the rollers is mounted on the guide member in a manner rotatable about its horizontal axis and rolls in a state of the U-shaped groove thereof being engaged with the upper and lower guide protrusions, it is possible to employ a guide member having a smaller width (or side-to-side dimension) compared with a case in which the whole of each roller is received in the guide member.
- the guide member can also serve as a partition wall for separating the upper spaces of the article passage from each other, so that the guide member having a reduced width allows larger space to be used for storing articles.
- the each of the rollers is equipped with a bearing.
- direct torque transmission between each of the rollers and its rotational shaft is prevented by the bearing, and frictional resistance produced between them during rotation of the roller is reduced to near zero, whereby the frictional resistance to the movement of the pusher on the guide member is further reduced.
- the pusher further comprises an auxiliary roller mounted on the pusher body at a location below the rollers, for rotation about a vertical axis of the auxiliary roller to roll on a side face of the body plate of the guide member.
- the auxiliary roller mounted on a lower side face of the pusher body rolls about its vertical axis to move on the body plate of the guide member in rolling contact therewith. Therefore, the urging face of the pusher body in contact with the articles can maintain perpendicularity with respect to a plane in which the guide member extends, whereby the frictional resistance to the movement of the pusher can be further decreased.
- the guide member is made of an extrusion molded article of aluminum.
- the guide member can have an increased strength and dimensional accuracy.
- the increased dimensional accuracy contributes to further reduction of the frictional resistance to the movement of the pusher on the guide member.
- the guide member is subjected to surface treatment by using alumite.
- the smoothness of the guide member is enhanced, whereby the frictional resistance to the movement of the pusher on the guide member is further decreased.

Abstract
Description
- This invention relates to an article storage device for a vending machine, and more particularly to an article storage device of this kind which stores a large number of articles in a manner placed one after another, and pushes out the articles one by one by means of a pusher to dispense them for vending.
- The present applicant proposed this kind of article storage device for a vending machine e.g. in Japanese Patent Application No. 9-69211. As shown in FIGS. 13 and 14, the
article storage device 50 includes a plurality ofarticle racks 51 arranged one above another, each of which is formed with a pair of right andleft article passages 52. Article S are stored in thesearticle passages 52. Eacharticle rack 51 is mounted in a body of the vending machine, not shown, such that it can be moved in a front-rear direction by means ofrollers 53,ball bearings 54, etc. and that it can be drawn out of the machine body. - Further, the
article rack 51 has a rack opening/closing plate 55 mounted at a front end thereof for opening/closing thearticle passage 52, and a pair ofpushers 56 each movably mounted behind the rack opening/closing plate 55 in a manner corresponding to therespective article passages 52. A large number of articles S are stored in thearticle passages 52 in a manner placed one after another between the rack opening/closing plate 55 and each of thepushers 56. Thepushers 56 are each slidably mounted on aguide rod 57 arranged in a front-rear direction under anupper article rack 51. While thepusher 56 can slide forward and backward along theguide rod 57, it is always urged forward byhelical tension springs 59 connected thereto by awire 58, etc. - According to the above construction, when the
article storage device 50 is to be replenished with articles S, an article rack requiring the replenishment is drawn forward out of the machine body, and then the articles S are placed one after another in eacharticle passage 52 with thepushers 56 being held within the machine body. After the replenishment, thearticle rack 51 is pushed back into the machine body, whereby each of thepushers 56 is pushed by a rearmost one of the articles S placed in thearticle passage 52 to be moved back to its predetermined backward position. In this state, the numerous articles S in thearticle passage 52 are sandwiched between the rack opening/closing plate 55 in its closed position and a corresponding one of thepushers 56 urged forward by thehelical tension springs 59. During a vending operation, the rack opening/closing plate 55 opens one of thearticle passages 52 to dispense a foremost one of the articles S therefrom. - However, there is room for improvement in the above
article storage device 50 to ensure smooth movement of thepushers 56. That is, in thisarticle storage device 50, eachpusher 56 is supported by acorresponding guide rod 57 in a manner hung therefrom, and hence thepusher 56 is in brought into contact with the rearmost article S at a lower point than a supporting point at which thepusher 56 is supported by theguide rod 57. Therefore, moment which acts on a lower portion of thepusher 56 to turn thepusher 56 backward about the supporting point is produced by a reaction force from the rearmost article S generated when thepusher 56 pushes the articles S forward, and by an urging force applied via the articles S to thepusher 56 when thearticle rack 51 is pushed back after being replenished. This causes thepusher 56 to be inclined with respect to theguide rod 57, whereby sliding (frictional) resistance to the movement of thepusher 56 on theguide rod 57 is increased. - Then the
pusher 56 pushes relatively light articles S, the sliding resistance is not significant so that no serious problem occurs. However, when articles S are heavy, or when frictional resistance between articles S and thearticle passage 52 is high, the sliding resistance between thepusher 56 and theguide rod 57 is much increased, causing a large loss of the urging force of thepusher 56. This demands a large urging force of the helical tension springs 59 for pushing the articles S forward for delivery. However, if the urging force of thehelical tension springs 59 is increased, it causes an increase in resistance produced when thearticle rack 51 is pushed back into the machine body after being replenished with articles S. This seriously affects ease of handling of thearticle rack 51. Further, when the article rack is pushed back, the urging force of the articles S acts on thepusher 56 to increase the inclination of thepusher 56 with respect to theguide rod 57. As a result, the sliding resistance between thepusher 56 and theguide rod 57 is increased, causing a large loss of operating force and hence also affecting the ease of handling of thearticle rack 51. Moreover, theguide rod 57 is very thin and long, and cannot avoid sagging to some degree, which also causes an increase in the sliding resistance of thepusher 56 on therod 57. - It is an object of the invention to provide an article storage device for a vending machine having a construction which is capable of reducing frictional resistance of a pusher to near zero, thereby making it possible to reduce the urging force required for moving the pusher forward and enhance ease of handling of an article rack in which the pusher is inserted for pushing articles.
- To attain the above object, the present invention provides an article storage device for a vending machine, including an article rack provided within a body of the vending machine in a manner such that the article rack can be moved in a front-rear direction and drawn forward out of the body of the vending machine, the article rack having an article passage formed therein for receiving a large number of articles one behind another, a rack opening/closing member provided at a front end of the article rack, for opening a dispensing opening of the article passage during a vending operation, and closing the dispensing opening except during the vending operation, a pusher inserted in the article passage, for pushing forward the articles received in the article passage, a guide member arranged above the article rack in a manner such that the guide member extends in the front-rear direction, for guiding the pusher in the front-rear direction, and urging means for urging the pusher forward.
- The article storage device according to the invention is characterized in that the guide member comprises a body plate extending vertically, and a guide portion integrally formed with the body plate, the guide portion having a pair of guide protrusions laterally spaced from the body plate and being vertically opposed to each other, and the pusher comprises a pusher body inserted into the article passage, and a pair of front and rear rollers each formed with a U-shaped groove and attached to an upper side of the pusher body in a manner rotatable about respective horizontal axes, the pusher being mounted between the vertically opposed guide protrusions of the guide portion of the guide member, with the U-shaped groove of each of the rollers being fitted on the vertically opposed guide protrusions.
- According to this article storage device for a vending machine, when the article rack is to be replenished with articles, it is drawn forward out of the machine body, and then the articles are placed one behind another in the article passage in a state of the pusher being held within the machine body. After the replenishment, the article rack is pushed back into the machine body, whereby a rearmost one of the articles placed in the article passage pushes the pusher back to its extreme backward position. Thus, the numerous articles are made ready for vending in a state sandwiched between the rack opening/closing member in its closed position and the pusher body of the pusher urged forward by the urging means. During a vending operation, the rack opening/closing member opens the dispensing opening of the article passage, whereby a foremost one of the articles placed in the article passage is dispensed from the article rack.
- As described above, the pusher moves backward along the guide member after replenishment of articles, with the pusher body thereof being pushed by the articles in the article passage, while it moves forward along the guide member during a vending operation, with the pusher body pushing the articles. In these cases, according to the invention, the pair of front and rear rollers mounted on the pusher body roll on the guide member, so that moment produced by a pushing force applied between the pusher body and the articles to act on the pusher body is absorbed by the rollers, whereby frictional resistance to the movement of the pusher on the guide member is considerably reduced. As a result, the urging force of the urging means required for moving the pusher forward can be reduced, which makes it possible to enhance ease of handling of the article rack after replenishment of articles.
- Further, since each of the rollers is mounted on the guide member in a manner rotatable about its horizontal axis and rolls in a state of the U-shaped groove thereof being engaged with the upper and lower guide protrusions, it is possible to employ a guide member having a smaller width (or side-to-side dimension) compared with a case in which the whole of each roller is received in the guide member. When the article rack has two article passage formed therein, the guide member can also serve as a partition wall for separating the upper spaces of the article passage from each other, so that the guide member having a reduced width allows larger space to be used for storing articles.
- Preferably, the each of the rollers is equipped with a bearing.
- According to this preferred embodiment, direct torque transmission between each of the rollers and its rotational shaft is prevented by the bearing, and frictional resistance produced between them during rotation of the roller is reduced to near zero, whereby the frictional resistance to the movement of the pusher on the guide member is further reduced.
- Preferably, the pusher further comprises an auxiliary roller mounted on the pusher body at a location below the rollers, for rotation about a vertical axis of the auxiliary roller to roll on a side face of the body plate of the guide member.
- According to this preferred embodiment, the auxiliary roller mounted on a lower side face of the pusher body rolls about its vertical axis to move on the body plate of the guide member in rolling contact therewith. Therefore, the urging face of the pusher body in contact with the articles can maintain perpendicularity with respect to a plane in which the guide member extends, whereby the frictional resistance to the movement of the pusher can be further decreased.
- Preferably, the guide member is made of an extrusion molded article of aluminum.
- According to this preferred embodiment, the guide member can have an increased strength and dimensional accuracy. The increased dimensional accuracy contributes to further reduction of the frictional resistance to the movement of the pusher on the guide member.
- Preferably, the guide member is subjected to surface treatment by using alumite.
- According to this preferred embodiment, the smoothness of the guide member is enhanced, whereby the frictional resistance to the movement of the pusher on the guide member is further decreased.

- The invention will now be described in detail with reference to drawings showing an embodiment thereof. Referring first to FIGS. 1 to 3, a
vending machine 2 to which the present invention is applied is a so-called see-through vending machine which allows vendible articles actually contained therein, such as canned or packed beverages, to be viewed from outside. Thevending machine 2 is comprised of amachine body 3 having anarticle storage device 1 of the invention installed therein, amain door 4 mounted on the front of themachine body 3, and a transparentheat insulating door 5 interposed between themain door 4 and themachine body 3. - As shown in FIGS. 2 and 3, mounted in a
storage box 3a of themachine body 3 are twenty four article racks 10 which are arranged in eight vertical layers and three horizontal rows. Each of the article racks 10 stores articles S of the same kind. On the front of themain door 4, there are arranged a plurality ofslots 4a, a plurality ofproduct selection buttons 4b, aproduct outlet 4c, and afront window 4d for allowing vendible articles to be viewed from outside to serve as a product display. Theselection buttons 4b each having a number identical to one assigned to a corresponding one of the article racks 10 are arranged in the form of a matrix corresponding to the array of the article racks 10. This construction permits viewing of the articles S in the article racks 10 through thefront window 4d and the transparentheat insulating door 5. A user can select and buy a desired article S by putting cash into any one of theslots 4a and then pushing aselection button 4b corresponding to anarticle rack 10 storing the desired article. - Within the
machine body 3, there are arranged a plurality of shelves 16 (see FIG. 5), and each of the article racks 10 is mounted on a corresponding one of theshelves 16 such that it can move in a front-rear direction thereon. Eacharticle rack 10 is received in themachine body 3, as shown in FIG. 3, when themachine 1 is ready for vending the articles S. On the other hand, when therack 10 is required to be replenished with articles S, it is drawn forward out of themachine body 3 as shown in FIG. 4. As shown in FIGS. 4 and 5, each of the article racks 10 is formed with a pair of right and leftarticle passage article passage storage box 3a has anelevator 6 arranged in a space in front of the array of article racks 10 such that theelevator 6 can move up and down between the ceiling of thestorage box 3a and ashutter 3b arranged on the bottom of the same. Theelevator 6 carries an article S dispensed from one of thearticle passages 11 on acarrier plate 6a down to the vicinity of theshutter 3b, and delivers the article S via theshutter 3b and theproduct outlet 4c. - Further, as shown in FIGS. 4 to 6, each of the article racks 10 has a front end thereof provided with a rack opening/
closing mechanism 7 for opening/closing thearticle passage 11. The rack opening/closing mechanism 7 is comprised of a pair of right and left rack opening/closing plates (rack opening/closing members) 12, 12, a spring, not shown, and anstopper plate 9 mounted in front of the pair of rack opening/closing plates 12 in a manner slidable on front surfaces thereof. Each of the rack opening/closing plates 12, which is formed of a transparent synthetic resin (e.g. polycarbonate), has a semicircular cut-away portion formed by cutting away a lower inside portion of theplate 12, and asemicircular protrusion 12a formed along the cut-away portion. Further, the rack opening/closing plates 12 are each mounted at the extreme front end of a corresponding one of the article racks 10 such that it can pivot about inside end portions thereof serving as a vertical axis of theplate 12. The rack opening/closing plate 12 can pivotally move between a closed position thereof for closing a dispensing opening 11a of a corresponding one of thearticle passage 11 and an open position thereof for opening the same. The rack opening/closing plates 12 are always urged by the spring in a rack opening direction (indicated by an arrow B in FIG. 6). Thestopper plate 9 formed by a circular plate of an opaque synthetic resin (e.g. polyacetal) is fixed to an end of adrive shaft 9a extending in a manner concentric with a circle formed by thesemicircular protrusions 12a of the rack opening/closing plates 12. Thedrive shaft 9a is connected to an stopper plate drive mechanism 13 (see FIG. 8), for being driven for rotation. - In the construction described above, when articles S are ready for vending, the
stopper plate 9 is held at an abutment position shown in FIG. 5 and 6 in which thestopper plate 9 is in abutment with theprotrusions closing plates plates 12 are each held in its closed position. In this state, a foremost one of the vendible articles S received in eacharticle passage 11 is in abutment with a corresponding one of theplates 12 in its closed position, whereby all the articles S in thearticle passage 11 are prevented from advancing. On the other hand, when an article S is to be delivered for vending, thedrive shaft 9a is driven by the stopperplate drive mechanism 13 for rotation through a predetermined angle, whereby thestopper plate 9 is rotated and shifted to one side by sliding on theprotrusions 12a of the rack opening/closing plates 12, to thereby release one of theplates 12 on an opposite side to the direction of the movement of thestopper plate 9. As a result, the releasedplate 12 is pivotally moved by the urging force of the spring to its open position for opening the dispensing opening 11a of a corresponding one of thearticle passage 11 to dispense the article S therefrom.Reference numeral 14 indicates a blocking plate which projects itself in a manner interlocked with rotation of thedrive shaft 9a for blocking a second article S to be sold next time from being dispensed together with the article S sold this time. - Further, as shown in FIGS. 5 and 7, the article racks 10 are each provided with a pair of right and left
pushers article passages 11 to dispense the same for vending, and aguide rail 17 for guiding thepushers - The
guide rail 17 is mounted at a central portion of the underside of a correspondingupper shelf 16 immediately above thepresent shelf 16 in a manner extending in a front-rear direction and at the same time protruding downward. Accordingly, theguide rail 17 also serves as a partition wall for separating upper spaces of therespective article passage guide rail 17 is comprised of abody plate 17a extending vertically, and a pair of right and leftguide portions body plate 17a at opposite side faces of thebody plate 17a, respectively. Eachguide portion 17b is comprised of a pair of upper andlower guide protrusions upper guide protrusion 17c protrudes downward from a horizontal portion extending laterally from a top of thebody plate 17a, and that thelower guide protrusion 17c extends laterally and obliquely from a bottom of thebody plate 17c and then protrudes upward in a manner opposed to theupper guide protrusion 17c. Theguide rail 17 is formed e.g. by an extrusion molded article of aluminum which is subjected to surface treatment by using alumite. - The
pushers 15 are each comprised of apusher body 15a inserted into a corresponding one of thearticle passages 11, for urging the articles S forward along thecorresponding article passage 11, a pair of front andrear rollers pusher body 15a, and anauxiliary roller 15c mounted on a lower side face of the same. Thepusher body 15a is in the form of a block made of a synthetic resin (e.g. polypropylene) and having a front surface serving as aflat urging face 15d for urging articles S forward. - The
rollers 15b are each equipped with a bearing, not shown, and mounted on the upper side face of thepusher body 15a such that each of them is capable of rolling about its horizontal axis. Each of therollers 15b has a peripheral surface formed with a V-shapedgroove 15e, and is mounted in theguide rail 17 in a state of the V-shapedgroove 15e being fitted on the upper andlower guide protrusions guide rail 17. This construction enables therespective rollers 15b to roll along theguide rail 17 with extremely small frictional resistance to move thepusher 15 forward and backward smoothly. - The
U-shaped groove 15e is formed such that the distance between two bottom points thereof diametrically opposite to each other is e.g. 19.5 mm, while the distance between the upper andlower guide protrusions U-shaped groove 15e. This dimensional relationship between theU-shaped groove 15e and the upper andlower guide protrusions rollers 15b from coming off theguide rail 17. Further, the pair ofrollers face 15d of thepusher body 15a, which allows the urgingface 15d to become upright when thepusher body 15a tilts due to pressure from the article S in contact therewith, so as to urge the articles S forward in this state. - The
auxiliary roller 15c (see FIG. 8) is mounted on the lower side face of thepusher body 15a such that it is rotatable about its vertical axis and rolls on the lower side face of thebody plate 17a of theguide rail 17. Theauxiliary roller 15c enables thepusher body 15a to maintain perpendicularity of the urgingface 15d thereof with respect to a plane in which theguide rail 17 extends, whereby the frictional resistance to the movement of thepusher 15 along theguide rail 17 can be further decreased. Thepusher 15 is always urged forward by a drive mechanism (urging means) 20, referred to hereinafter, and held in engagement with theguide rail 17 when it moves to its extreme forward position. - Next, the operation of the article storage device constructed as above will be described. When an
article rack 10 is required to be replenished with articles S, thearticle rack 10 is drawn forward out of themachine body 3 as shown in FIG. 4, and a large number of articles S are placed one behind another in each of thearticle passages 11, with thepusher 15 held in engagement with themachine body 3. When thearticle rack 10 is pushed back into themachine body 3 after the replenishment, each of thepusher bodies 15a is urged backward by a rearmost one of the articles S received in a corresponding one of thearticle passage 11, whereby thepusher 15 is moved along theguide rail 17 together with thearticle rack 10 from its extreme forward position shown by solid lines in FIG. 9 to its extreme backward position shown by phantom lines in the same figure. As a result, the numerous articles S are held in a state sandwiched between the rack opening/closing plate 12 held in its closed position by thestopper plate 9 and thepusher body 15a of thepusher 15 urged forward by thedrive mechanism 20, and thus made ready for vending. - On the other hand, during the vending operation, the stopper
plate drive mechanism 13 drives thedrive shaft 9a for rotation through a predetermined angle, whereby thestopper plate 9 slides in one direction to release one of the rack opening/closing plates 12 on an opposite side to the direction of the movement of thestopper plate 9. The released rack opening/closing plate 12 is pivotally moved to its open position by the urging force of the spring, whereby the dispensing opening 11a of thearticle passage 11 is opened for dispensing an article S from thearticle passage 11. At this time point, an article S immediately behind the dispensed article S is blocked by the blockingplate 14 from being dispensed from thearticle passage 11. - As described above, after the replenishment of articles S, the
pusher 15 moves backward along theguide rail 17 in a state of itspusher body 15a being pushed by the articles S, while during a vending operation, it moves forward along theguide rail 17 in a state of itspusher body 15a pushing the articles S. In the present embodiment, the front andrear rollers pusher body 15a roll on theguide rail 17, and further, therollers 15b are each equipped with the bearing for preventing direct torque transmission between theroller 15b and its rotational shaft, so that moment on thepusher body 15a produced by the urging force acting between the articles S and thepusher body 15a is absorbed by therollers pusher 15 can be far more reduced compared with the conventional construction of the article storage device. - Further, the above characteristic features and advantages of the present invention that the
auxiliary roller 15c rolling on the side face of thebody plate 17a of theguide rail 17 enables thepusher body 15a to maintain perpendicularity of the urgingface 15d thereof with respect to a plane in which theguide rail 17 extends, that theguide rail 17 can be produced to close dimensional tolerances by using an extrusion molded article, and that theguide rail 17 is improved in smoothness of guide surfaces thereof by surface treatment by using alumite all contribute to further decreasing the frictional resistance to the movement of thepusher 15 to near zero. As a result, the urging force of the drive mechanism required for moving thepusher 15 forward can also be reduced, which enhances ease of handling of thearticle rack 11 when replenishment of vendible articles is carried out. - Moreover, since the
rollers guide rail 17 such that they are rotatable about their respective horizontal axes with the U-shaped grooves thereof being engaged with the upper andlower guide protrusions guide rail 17 such that it has a smaller width (dimension in a side-to-side direction of the vending machine), compared with a case in which the whole of eachroller 15 is received in theguide rail 17. Theguide rail 17 also serves as a partition wall for separating the upper spaces of thearticle passage guide rail 17 having a reduced width allows larger space to be used for storing articles S. - Next, the above-mentioned
drive mechanism 20 for urging acorresponding pusher 15 will be described in detail with reference to FIGS. 8 to 12. Thedrive mechanism 20 is provided for each pusher 15 (see FIG. 11 etc.) and received between an upper case plate 21 and alower case plate 22 which protrude from the respective top side and bottom side surfaces of a corresponding one of the shelves 16 (see FIGS. 8 and 9). Thesecase plates 21, 22 are each constructed to have a small protrusion dimension, i.e. form a container having a small thickness or height. Thedrive mechanism 20 is connected to thepusher 15 by awire 19. Thewire 19 is passed over asmall pulley 18 arranged at a front end of the bottom side surface of theshelf 16 and then connected to ahook 15f formed on the top of thepusher 15. - As shown in FIG. 10, the
drive mechanism 20 includes areduction mechanism 23 comprised of apulley gear 24, anintermediate gear 25, and adrum gear 26, which mesh with one another. Thegears lower case plates 21, 22. Thepulley gear 24 is comprised of apulley 24a over which thewire 19 is passed and agear 24b formed integrally on the upper side of thepulley 24a. Theintermediate gear 25 is comprised of alarge gear 25a in mesh with thegear 24b and asmall gear 25b integrally formed with thelarge gear 25a. Thesmall gear 25b of theintermediate gear 25 meshes with agear 26a of thedrum gear 26. Acylindrical drum 26b is formed integrally on the lower side of thegear 26b. - On the underside of the
drum gear 26, there are formed twoprojections hooks shelf 16. - In the
drive mechanism 20 constructed as above, when thearticle rack 10 is pushed back into themachine body 3 after being replenished with articles S, to thereby move thepusher 15 to its extreme backward position along theguide rail 17, thewire 19 is pulled, whereby thepulley gear 24 rotates in a counterclockwise direction, as viewed in FIG. 10B, to cause thedrum gear 26 to rotate in the same direction via theintermediate gear 25. As thedrum gear 26 rotates, the helical tension springs 30 are each extended through being wound around thedrum 26b. - As described above, the
drive mechanism 20 makes it possible to secure a longer range of travel of thepusher 15 with respect to a limited length of expansion of each of the helical tension springs 30 through the combination of the helical tension springs 30 and thereduction mechanism 23. Further, the urging force of the helical tension springs 30, i.e. an urging load on thepusher 15 is maximized when thepusher 15 is at its extreme backward position, and minimized when thepusher 15 is at its extreme forward position. Still further, the two helical tension springs 30, 30 connected to thegear 26a of thedrum gear 26 in a manner point-symmetrical and parallel with each other transmit torque to thedrum gear 26 in a dynamically well-balanced fashion, thereby enabling thepusher 15 to be urged smoothly.Reference numeral 27 appearing in FIGS. 10A to 12 indicates a sold-out switch for detecting a sold-out state of articles S in a corresponding one of thearticle passages 11. Thisswitch 27 is turned on by aprojection 26d formed on thedrum gear 26 when thepusher 15 moves to its extreme forward position. - The present invention is not limited to the above embodiment, but it can be practiced in various forms. For instance, although in the above embodiment, each article rack is formed with a pair of right and left article passages, and two pushers each provided for one of the article passages are guided along an identical guide rail, this is not limitative, but the invention may be applied to an article rack having a single article passage formed therein.
- It is further understood by those skilled in the art that the foregoing is a preferred embodiment of the invention, and that various changes and modifications may be made without departing from the spirit and scope thereof.
