  • Publication number: 20150053713
    Abstract: A sanitized vending machine includes product and cup dispensing mechanisms and an actuation mechanism. The product dispensing mechanism, holding product items, rotates through a product dispensing cycle to dispense them. The cup dispensing mechanism, holding a stack of cups, rotates through a cup dispensing cycle to dispense an empty cup to an intermediate location in a drop chute spaced above a final discharge location. Dispensing cycles occur in a predetermined sequence enabling the dispensed product items to be received in a dispensed empty cup and the cup dropped to the discharge location. An access door locking mechanism is coupled to the actuation mechanism so as to maintain the access door in a locked condition and closed position from start of an actuation cycle to completion thereof whereupon the access door is converted to an unlocked condition permitting a user to open the access door and remove a cup with product items.

  • Patent number: 5799824
    Abstract: An apparatus and method of deterring or reducing breakage or deformation when dispensing a vertical stack of containers. A blocking member used to restrict dispension of vertical stack containers above a container being dispensed, can have a biasing member associated with it to allow it to vertically move to cause the stack to drop in a controlled fashion so that the block is not forced into the side walls of the containers, and so the dropping of the containers is controlled in a manner to reduce or deter the likelihood of breakage or deformation of the containers. An alternative feature of the invention is the use of a biasing member to return the blocking member to an original member to an original position once the weight of any vertical stack above it is removed.

  • Patent number: 5791516
    Abstract: A dispensing apparatus and method for vending machines includes in one embodiment vertical vending from one or more columns. Each column is defined by two walls. A triggering mechanism at the bottom of the column is actuated by the rotation of a rod from the top of the column. The triggering mechanism blocks items placed along the column from being dropped out the bottom of the column to a delivery area but also controls when such dispensation occurs. The configuration allows items of different sizes, shapes, and types to be loaded into the column and therefore allows the column to be easily adapted to dispense a wide variety of items.

  • Patent number: 5100019
    Abstract: A pair of superposed inclined feed tracks have slots along their upper and lower walls respectively. Elongate gates with inturned tips are disposed along the tracks and pivoted intermediate their ends on pins. A yoke having an axis intermediate the two pins has outward parallel fingers which are disposed outward of the pins, and as the yoke is turned by a rotary solenoid, first in one direction and then the other, the fingers engage the gates on opposite sides of their pivot pins oppositely and alternately to alternately open and close the respective tracks. A reciprocating pusher pushes the parts into the working ends of the upper and lower dies and a settable counter counts the strokes of the pusher. A circuit causes activation of the solenoid to shift the gates to switch the feed from one feed track to the other track when the counter registers up to the set number of strokes.

  • Patent number: 4854477
    Abstract: A control device for a dispense mechanism is provided for eliminating failure of the dispense mechanism due to goods becoming stuck therein. In a dispense mechanism of the type wherein a rotating control plate is provided for restricting the motion of dispensing flappers, a control device is provided for controlling the operation of a motor which rotates the control plate. The control device provides a forward rotation signal to rotate the control plate and dispense goods in response to a dispense request. The control device further determines whether an article has become stuck by determining whether the flappers return to their original position while the control plate is being rotated. If an article is struck, the control device rotates the motor in the reverse direction such that the stuck article may be freed. Thereafter, the control device is rotated in a forward direction and again the determination is made whether the flappers have moved to their original position.

    Abstract: A circuit reciprocator or alternator arrangement for alternately operating two vend motor-driven stack mechanisms loaded with the identical product brand from a single common customer-operable selector switch. An on-on type switch having SPDT contacts for alternately completing a circuit to the two vend motors is operated by an actuating linkage. The linkage is arranged such that switching or toggling of the on-on switch occurs prior to a particular known point or range of points of the vend cycle where the probability of a mechanism jam is higher. Therefore, if one of the vend motors jams, the circuit has already been completed to the other vend motor which can then be subsequently actuated. Further, the on-on switch is geld in a position where no furhter toggling or switching occurs, and the circuit will continue to be completed to the other, unjammed motor. The linkage is further arranged such that no damage occurs when one motor is stalled and the other continues to operate.
