Definitions

  • the invention relates to a product housing apparatus and a product housing method for a vending machine, for housing therein a plurality of products arranged in the longitudinal direction which, at the time of selling, are pushed forward from behind to deliver a product. More particularly, the invention relates to a product housing apparatus and a product housing method for a vending machine, for housing therein, for example, thin products such as wrapping with an emblematic noshi decoration printed on it (noshi bukuro), bagged products such as snack confectionery, and wholly wrapped products (hereinafter referred to as "wrapped products”) such as box lunches.
  • the spiral member is rotated by substantially one turn about an axis extended in the longitudinal direction to advance products by one pitch while pushing.
  • the rotation of the spiral member in this way permits all the products housed in the product passage to be moved forward, and, when the spiral member has been rotated at a predetermined angle, the product located at the forefront in the product passage (hereinafter referred to as "forefront product”) is delivered forward from the delivery port located at the front end of the product passage.
  • spiral member In the vending machine provided with the spiral member, a large number of spiral members should be provided according to the size and shape of the products. Specifically, in order to properly deliver the products forward in a substantially stood-up position, it is necessary to use a spiral member which has a diameter close to the outside dimension of the product and has a space somewhat larger than the thickness of the products. Therefore, in order to sell a variety of products having various sizes and thicknesses, a plurality of types of spiral members should be provided according to the types of the products. This disadvantageously increases the cost.
  • a failure to deliver is likely to occur particularly in delivering a thin product from the product passage to the bucket. More specifically, an unavoidable gap occurs between the bucket moved around the delivery port in the product passage and the delivery port in the product passage.
  • a failure to deliver products is likely to occur for some products, Specifically, for example, when wrapped products are housed in the product passage in such a state that they are merely placed on the bottom wall in the product passage, the lower surface of the wrapped product is brought into intimate contact with the bottom wall in the product passage. This often causes large frictional force between the wrapped products and the bottom wall in the product passage. For this reason, in some cases, the pusher driving force is unsatisfactory for delivering the wrapped products, even though this driving force suffices for advancing canned beverage products or the like. In this case, the wrapped products cannot be properly advanced. As a result, a failure to deliver the products occurs.
  • the invention has been made with a view to solving the above problems of the prior art, and it is an object of the invention to provide inexpensive product housing apparatus and product housing method for a vending machine which can house, in a product passage horizontally extended in the longitudinal direction, various products including, for example, thin products, bagged products, and wrapped products, in the state of being arranged in the longitudinal direction, and, at the same time, can properly and surely deliver the products.
  • a product housing apparatus for a vending machine, for housing therein a plurality of products arranged in the longitudinal direction which, at the time of selling, are pushed forward from behind to deliver a product, said product housing apparatus comprising:
  • a plurality of products to be arranged in the longitudinal direction for housing in the state of being abutted against each other in a product passage defined by the bottom wall and the left and right side walls are locked by a product locking section provided between the left and right side walls of the bottom wall.
  • 1 ⁇ two products abutted against each other are housed in the product passage so as to cross each other by locking two products abutted against each other in such a manner that one of the two products is held in a position inclined in the lower right direction while the other product is held in a position inclined in the lower left direction (hereinafter referred to as "cross housing”).
  • 2 ⁇ all the products are locked so as to be held in a position inclined in an identical direction, that is, the lower right direction or the lower left direction, at substantially the same angle to house them in the product passage (hereinafter referred to as "identically inclined housing").
  • the plurality of products housed in the product passage in this way are pushed forward from behind, whereby, while maintaining the position in the housed state, the products are moved forward along the product passage while being guided by the locking section, and then delivered.
  • the plurality of products housed in the product passage are housed in a laid state and in a position inclined in the lower right direction and/or the lower left direction.
  • these products are housed by cross housing.
  • simply pushing these products forward from behind permits the products to be delivered from the product passage. Therefore, unlike the prior art, even when products to be housed are thin products or bagged products, there is no need to provide a large number of types of spiral members according to the products housed in the product passage.
  • a product housing apparatus which can house various products including thin products and bagged products, can be realized at low cost.
  • the bucket when the bucket is moved to the vicinity of the delivery port in the front end of the product passage to receive the product delivered from the product passage and, at the same time, when the product is a thin product or a bagged product, the product is delivered while being moved forward by at least the depth in a laid state (the lateral width or longitudinal width of the product). Further, at that time, since the depth is generally larger than the gap between the bucket and the delivery port, for example, the entry of the product into the gap can be surely prevented. This permits the product to be properly and surely delivered (handed) to the forward bucket.
  • the frictional force can be significantly reduced by housing the product in a position inclined in the lower right direction or the lower left direction, because the product comes into line contact with the bottom wall to give a very small contact area.
  • wrapped products and the like can be smoothly and surely delivered forward, and, thus, a failure to deliver products can be prevented.
  • the product locking section comprises a convex which is projected upward from the bottom wall and locks the plurality of products.
  • the product locking section can be constituted by a convex projected upward from the bottom wall and having a simple construction in a low-cost and simple manner.
  • the convex is disposed at a substantially center portion between the left and right side walls of the bottom wall.
  • a convex is disposed at a substantially center portion between the left and right side walls of the bottom wall. Therefore, products abutted against each other can be allowed to cross each other in the vicinity of the upper end of the convex, and housed orderly within the product passage symmetrically with respect to the left and right about the convex.
  • the convex is constructed so as to be detachable from the bottom wall and attachable to a plurality of positions between the left and right side walls of the bottom wall,
  • the convex is detachable to the bottom wall, and is attachable to a plurality of positions of the bottom wall in the lateral direction. Therefore, the form of housing can be freely and easily switched between cross housing and identically inclined housing, for example, according to the size or shape of the product to be housed. specifically, when a convex is mounted on a center portion between the left and right side walls of the bottom wall, the products can be housed by the cross housing, while when the convex is mounted at a position which is closer to any one of the left and right side walls than the other side wall, the products can be housed by the identically inclined housing.
  • the convex is detachable from the bottom wall, when products which require neither cross housing nor identically inclined housing, for example, products which can be placed in a self-stood-up position on the bottom wall, such as canned beverage products, are housed in the product passage, the removal of the convex from the bottom wall can easily cope with this.
  • the surface of the convex is formed of a material having a sliding property.
  • the surface of the convex has a sliding property. Therefore, when the products locked by the convex are pushed forward from behind, they can be smoothly delivered forward.
  • the product locking section comprises a concave which is provided on the upper surface of the bottom wall and functions to lock the lower end of the plurality of products housed in the inclined position in the product passage.
  • the product locking section for locking the lower end of the plurality of products housed in an inclined position can be formed by the concave having a simple structure provided on the upper surface of the bottom wall in a low-cost and simple manner.
  • the concave is provided at a substantially center portion between the left and right side walls of the bottom wall.
  • a concave is provided at a substantially center portion between the left and right side walls of the bottom wall. Therefore, products abutted against each other can be allowed to cross each other in the concave, and housed orderly within the product passage symmetrically with respect to the left and the right about the concave.
  • two concaves may be provided, symmetrically with respect to the left and the right, between the left and right side walls of the bottom wall.
  • At least one of the left and right side walls is constructed so as to be detachable from the bottom wall and attachable to a plurality of positions in the lateral direction of the bottom wall.
  • At least one of the left and right side walls is detachable to the bottom wall, and is attachable to a plurality of positions of the bottom wall in the lateral direction. Therefore, the width in the lateral direction of the product passage can be freely and easily increased or reduced, for example, according to the size or shape of the product to be housed in the product passage.
  • the above product housing apparatus further comprises a detachable cover which is extended in the longitudinal direction along the left and right side walls and covers, from the product passage side, a gap between the bottom wall and at least one of the left and right side walls.
  • the covering of the gap with a cover from the product passage side can surely prevent accidental entry of the product in its end (a front end in the case of thin products, and a double leaved ear portion in the case of bagged products) into the gap at the time of housing or delivery of products.
  • the cover on its surface of the product passage side is preferably formed of a material having a sliding property.
  • the surface of the cover on its product passage side has a sliding property, the product housed in contact with the cover can be smoothly advanced by pushing the product forward from behind.
  • any one of the above product housing apparatuses may further comprise a product delivery sensor which comprises a light emitting device and a photodetector located around a delivery port of the front end of the product passage and provided so as to horizontally face each other in the lateral direction and detects the delivery of a product from the product passage based on whether or not light from the light emitting device has been received by the photodetector.
  • a product delivery sensor which comprises a light emitting device and a photodetector located around a delivery port of the front end of the product passage and provided so as to horizontally face each other in the lateral direction and detects the delivery of a product from the product passage based on whether or not light from the light emitting device has been received by the photodetector.
  • the product delivery sensor comprising the light emitting device and the photodetector detects a product which is delivered while maintaining the position provided at the time of housing. Specifically, the detection is made based on whether or not, in passing the product, which is in a laid state and held in a position inclined in the lower right direction or the lower left direction, through between the light emitting device and the photodetector, the photodetector has received light from the light emitting device.
  • the product to be delivered is a thin product
  • the height of the product in the vertical direction is larger by the degree of inclination than that in the case where the product is delivered in the horizontally laid state. Accordingly, the delivery of this product can be surely detected by properly setting the angle of inclination of the product so as to apply light from the light emitting device to the product.
  • a product housing method for a vending machine for housing a plurality of products which are abutted against each other and arranged in the longitudinal direction in a product passage horizontally extended in the longitudinal direction and, at the time of selling, are pushed forward from behind to deliver a product, wherein one of the plurality of the products is housed, within the product passage, in a laid state and in a position inclined in one of the lower right direction and the lower left direction, and the other product abutted against said one product is housed, within the product passage, in a laid state and in a position inclined in the other direction.
  • housing the products in the product passage by the cross housing permits the product to be delivered while being moved forward by at least the depth in a laid state (the lateral width or longitudinal width of the product) Further, at that time, since the depth is generally larger than the gap between the bucket and the delivery port, for example, the entry of the product into the gap can be surely prevented, This permits the product to be properly and surely delivered forward.
  • the cross housing of the products can significantly reduce the frictional force, because the product comes into line contact with the bottom wall to give a very small contact area.

  • the product S located in the forefront is delivered forward through the delivery port 14a of the product passage 14. As soon as the product delivery sensor 51 detects the receipt and housing of the forefront product S in the bucket 43 through the product housing opening 44, the rotation of the drive gear 48 is stopped to stop the forward movement of the pusher 24.
  • the convex member 33 mounted on the product rack 12 permits these products S to be housed by cross housing wherein the products S are arranged in the longitudinal direction in a laid state and in such a position that the products S are inclined alternately in the lower right direction and in the lower left direction.
  • the housing in this way, the products S can be delivered from the product passage 14 by simply pushing the products S from behind, without causing a trouble such that products located in the rear run on or are slipped under products located in the front.
  • a product housing apparatus 4 which can house various products including thin products and bagged products, can be realized at low cost.
  • the product S is delivered while being moved forward by at least the lateral width or the longitudinal width.
  • the lateral width or the longitudinal width is generally larger than the gap between the bucket 43 and the delivery port 14a, for example, the entry of the product S into the gap can be surely prevented, permitting the product S to be properly and surely delivered (handed) to a bucket 43 in front.
  • the convex member 33 has a simple structure, the product locking section for cross housing products S can be simply constructed at low cost.
  • the surface of the convex member 33 and the surface of the cover 34 on its product passage 14 side have a sliding property. Therefore, in pushing the product S locked by the convex member 33 and the cover 34 by means of the pusher 24, the product S can be smoothly delivered forward.
  • the convex member 33 is disposed at a substantially center portion between the left and right partition walls 13, 13 in the product rack 12, products S abutted against each other can be allowed to cross each other around the upper end of the convex member 33, and can be orderly housed symmetrically about the convex member 33 with respect to the left and the right.
  • the product delivery sensor 51 provided on the bucket 43 detects a product S delivered through the delivery port 14a in the product passage 14, the product S is delivered in a laid state and in a position inclined in the lower right direction or in the lower left direction. Therefore, the delivery of the product can be surely detected as compared with the detection of the product delivered in a horizontally laid state.
  • the second preferred embodiment can be applied to housing of wrapped products, for example, packed lunches, in the product passage 14 by identically inclined housing.
  • This product housing apparatus is the same as the product housing apparatus 4 according to the first preferred embodiment, except that the convex member 33 is provided at a position closer to the left partition wall 13 than the right partition wall.
  • the right end in one of the plurality of products S is abutted against the right cover 34, while the left end is abutted against the convex member 33 from its upper part, thereby housing the one product S in the product passage 14.
  • another product S is housed in the same manner as used in the one product S in such a state that the another product S is abutted against the one product S on its front or rear side.
  • the another product S is locked by the convex member 33 and the right cover 34 and is housed in the state of being held in a position inclined at an angle substantially identical to the inclination angle of the one product S.
  • Products S are successively housed in this way, whereby a plurality of products S are housed in the product passage 14 by identically inclined housing.
  • the plurality of products S housed in the product passage 14 by identically inclined housing in the lower right direction are pushed forward from behind by the pusher 24 and consequently are delivered forward. More specifically, as shown in Figs. 5 and 6, each product S housed in the product passage 14 is pushed forward by the pusher 24 in such a state that the right end and the left end are locked respectively by the right cover 34 and the convex member 33. Therefore, while maintaining the position provided at the time of housing, the products S are delivered forward while being guided by the right cover 34 and the convex member 33.
  • each product S has certain thickness (substantial height in the vertical direction of the product), the product S can be advanced without causing a trouble such that, at the time of pushing by the pusher 24, products located in the rear run on or are slipped under products located in the front.

  • the product housing apparatus 4 and product housing method according to this preferred embodiment have the following effects in addition to substantially the same effect as attained by the first preferred embodiment. Specifically, since the convex member 33 is disposed at a position closer to the left partition wall 13 than the right partition wall 13, the inclination angle of the product S can be made smaller as compared with the housing of products by cross housing according to the first preferred embodiment. Therefore, in the case of products which, when housed in an inclined state, cause the contents to be easily crumbled, housing these products by the identically inclined housing method can suppress the crumbling of the contents.
  • the convex member 33 may be disposed at a position closer to the right partition wall 13 than the left partition wall to house products S by identically inclined housing in the lower left direction. Also in this case, the same effect as attained by the identically inclined housing in the lower right direction can be attained. Further, the product housing apparatus 4 and product housing method according to this preferred embodiment can be applied to the housing of the above-described wrapped product, as well as to the housing of thin products and bagged products. In this case, preferably, the products have certain thickness (height) from the viewpoint of avoiding such a trouble that, at the time of pushing by means of the pusher 24, products located in the rear run on or are slipped under products located in the front.
  • the convex member 33 is attachable to and detachable from the product rack 12, and can be attached to a plurality of positions in the lateral direction of the product rack 12. Therefore, the housing method can be freely and easily switched between cross housing and identically inclined housing according to the size and shape of the product S to be housed. Specifically, mounting the convex member 33 at a substantially center portion between the left and right partition walls 13, 13 in the product rack 12 enables products S to be cross housed. On the other hand, mounting the convex member 33 at a position closer to one of the left and right partition walls 13, 13 than the other partition wall enables products S to be housed by identically inclined housing.
  • the convex member 33 is detachably mounted on the product rack 12, the removal of the convex member 33 from the product rack 12 suffices for housing of products which require neither cross housing nor identically inclined housing, for example, canned beverage products which can be housed in the product passage 12 by placing them in a self-stood-up state on the product rack 12.
