Definitions

• Vending machines exist for dispensing a chosen and paid article after payment and selection has been made by a consumer. It is possible to envisage here for instance rolls of film as well as measured quantities of food products, for instance drinks cans, tubs of yoghurt, bars of chocolate and the like.
• Such a vending machine shows on the front side or viewing side which products are offered for sale.
• the closable front door can for instance have a window of glass or an acryl material .
• the products or articles in question are situated on carriers ordered one above another, while means are present for displacing the article in question over the free front edge of the relevant carrier after a selection and payment have been made by a user such that the article drops downward via a free space between the front edge of the carrier and the front door, whereafter the falling article is received in a receiving bin placed at low height.
• Connecting onto this bin is an access opening optionally closable by means of a swing door or lid, via which opening the user can remove an article lying in the receiving bin.
• the invention provides an auxiliary device for adding to a device for dispensing a selected article in accordance with the choice of a user; which device comprises: a housing with a closable, optionally transparent front door; carrier means accommodated in this housing for carrying stocks of articles, optionally of different types, at different heights, which carrier means also comprise transport means for dispensing the chosen article on the free front side of the carrier means at a height specific to the choice which has been made, this under the control of control means controlled by a user by means of operating means, the free front side of which carrier means is situated at a certain free spacing from the front door in closed position; a receiving bin accommodated in the housing for receiving a dispensed article; and an access opening, via which the user can remove an article lying in the receiving bin; which auxiliary device comprises: lifting means for carrying the receiving bin to said specific height prior to dispensing of an article and for carrying the receiving bin to the height of the access opening after dispensing, which lifting means are movable up and downward in the space defined
• a specific embodiment of the auxiliary device according to the invention has the special feature that the carrier means are adapted to carry the articles in mutually parallel rows.
• a simple and reliable embodiment has the special feature that the transport means comprise respective endless conveyors .
• the transport means comprise respective pairs of synchronously drivable helical conveyors at equal pitch distances.
• the helical conveyors can for instance be embodied as substantially rigid helically wound wires, pairs of which have a pitch in opposing directions. This effectively avoids the occurrence of a lateral force component, whereby reliable transport is ensured in longitudinal direction of the row in question.
• these articles or groups of articles can be carried by respective carriers which are mechanically capable of being transported by the helical conveyors.
• a very simple and reliable structure is that in which the receiving bin is vertically guided and driven on both sides .
• Another aspect of the invention can entail driving taking place by means of two chains or toothed belts which are coupled to the receiving bin on the respective sides.
• a motor optionally via a reducing transmission, can for instance drive a horizontal drive shaft, on both ends of which is situated a toothed wheel round which the respective chains or toothed belts are trained.
• a perfect synchronization of the drive on both sides and a perfect horizontal position of the receiving bin are hereby always ensured.
• the vertical guiding can take place by making use of per se known guide means, for instance two rails and slide or roller elements co-acting therewith.
• a very inexpensive, maintenance-free and reliable guide can be based for instance on sliding.
• An advantageous embodiment of the invention is one wherein substantially all components of the auxiliary device are mounted on a frame.
• a frame can be incorporated in simple and rapid manner in an existing vending machine according to the prior art.
• the invention relates to the combination of a per se known dispensing device for articles and an auxiliary device provided with lifting means which is added to the dispensing device.
• the auxiliary device can be accommodated in very simple manner in the space defined by the free spacing between the free front part of the carriers and the front door, particularly when the components of the auxiliary device are mounted on a frame which can be placed in simple manner in an existing vending machine.
• the described combination can advantageously have the special feature that the auxiliary device is arranged on the inner surface of the front door.
• the invention also relates to a method for dispensing a selected article in accordance with the choice of a user, comprising the steps of: carrying stocks of articles, optionally of different types, at different heights in a housing with a closable, optionally transparent front door; dispensing a chosen article on the free front side of the stocks of articles at a height specific to the choice which has been made, the free front side of which stocks of articles is situated at a certain free spacing from the front door in closed position; receiving the dispensed article in a receiving bin accommodated in the housing; removing by the user of the article lying in the receiving bin via an access opening; which method further comprises the steps of: carrying the receiving bin to said specific height prior to dispensing of the article and carrying the receiving bin to the height of the access opening after dispensing, by moving the receiving bin up and downward in the space defined by said free spacing.
• the selection made by the user corresponds with dispensing of a specific article.
• This article is dispensed at a height determined by the control means via memory means.
• the receiving bin Prior to dispensing the receiving bin must be transported from the level of the dispensing opening (the rest position) to the relevant dispensing height .
• optical means for instance a light source and a photocell added thereto.
• Such a combination can be added to each carrier.
• the advantage of such a structure over an alternative consisting of the use of a stepping motor is that when the lay-out of the device is changed, in particular when the height of the carriers is changed, no reprogramming steps for the central control means are required. Energizing of the lifting means is in any case interrupted immediately on reaching the height defined by the shelf and the optical means added thereto.
