Abstract

A system and method according to which ice is automatically disposed in respective bags and the bags of ice are distributed and stacked within a temperature-controlled storage unit, such as an ice merchandiser.

Claims

1. An apparatus, comprising:

a temperature-controlled storage unit, the temperature-controlled storage unit defining a region in which a plurality of ice-filled bags are adapted to be stored, each of the ice-filled bags having a length, a width, a top portion via which the ice-filled bag is filled with ice, and a bottom portion opposing the top portion along the length;

wherein the storage unit comprises;

front and back inside walls spaced in a parallel relation;

an opening formed in the front inside wall; and

at least one door connected to the front inside wall, the door being movable between an open position in which access to the region via the opening is permitted, and a closed position;

and

wherein the region comprises;

a front row comprising a plurality of disposal zones, each disposal zone of the front row being adjacent to the front inside wall; and

a back row comprising a plurality of disposal zones, each disposal zone of the back row being adjacent to the back inside wall;

a basket in which each of the ice-filled bags is adapted to be disposed before being stored in the region;

wherein the basket is rotatable, about a first axis, between a first rotational position and a second rotational position;

wherein the basket is movably coupled to the storage unit so that at least a portion of the basket is permitted to move within the region along a second axis, the second axis being generally perpendicular to the first axis;

wherein the basket is rotatable about a third axis in a first rotational direction and a second rotational direction, the first rotational direction being opposite the second rotational direction;

wherein the third axis is generally perpendicular to the second axis when the basket is in the first rotational position;

wherein the third axis is coaxial with, or generally parallel to, the second axis when the basket is in the second rotational position;

wherein the third axis is generally perpendicular to the first axis when the basket is in the first rotational position and the second rotational position;

wherein the first axis extends through the basket;

wherein the second axis extends through the basket;

wherein the third axis extends through the basket;

wherein the first axis intersects with the second axis at a location within the basket; and

wherein the first axis intersects with the third axis at the location within the basket;

a first motor coupled to the basket and configured to rotate the basket about the first axis;

a second motor coupled to the basket and configured to rotate the basket about the third axis;

a ring bearing, the ring bearing comprising a first ring and a second ring coupled thereto and circumferentially extending thereabout,

wherein the ring bearing is configured to permit relative rotation between the first and second rings and about the first axis, and

wherein the first and second motors are coupled to one of the first and second rings;

a first sensor coupled to the one of the first and second rings so that the first sensor is positioned at a first location;

a second sensor coupled to the one of the first and second rings so that the second sensor is positioned at a second location that is generally diametrically opposite the first location;

a carriage to which the other of the first and second rings is coupled;

and

an opening formed through the carriage and through which ice passes to fill each of the ice-filled bags;

wherein the first axis extends through the opening; and

wherein at least a portion of the opening is positioned above at least a portion of the basket;

wherein the basket, the first and second motors, the first and second sensors, and the one of the first and second rings are rotatable, about the first axis and relative to the carriage, the opening, and the other of the first and second rings;

wherein the carriage is movably coupled to the storage unit to thereby movably couple the basket to the storage unit;

wherein, when a first ice-filled bag in the plurality of bags is initially disposed in the basket, the width of the first ice-filled bag is generally perpendicular to the door when the door is in the closed position, and the length of the first ice-filled bag is generally parallel to the door when the door is in the closed position;

wherein the first ice-filled bag in the plurality of ice-filled bags is stackable in the region in response to the rotation of the basket about the third axis in the first rotational direction when the basket is in the second rotational position at a first position along the second axis, the first ice-filled bag being stackable so that the length of the first ice-filled bag is generally perpendicular to the door when the door is in the closed position;

wherein, when a second ice-filled bag in the plurality of bags is initially disposed in the basket, the width of the second ice-filled bag is generally perpendicular to the door when the door is in the closed position, and the length of the second ice-filled bag is generally parallel to the door when the door is in the closed position;

wherein the second ice-filled bag in the plurality of ice-filled bags is stackable in the region in response to the rotation of the basket about the third axis in the second rotational direction when the basket is in the second rotational position at the first position along the second axis, the second ice-filled bag being stackable so that the length of the ice-filled bag is generally perpendicular to the door when the door is in the closed position; and

wherein, when the first and the second ice-filled bags are stacked in the region;

the first ice-filled bag is stacked in a first disposal zone located in one of the front and back rows;

the second ice-filled bag is stacked in a second disposal zone located in the other of the front and back rows;

the top portion of the first ice-filled bag and the top portion of the second ice-filled bag are each positioned about midway between the front and the back inside walls;

the bottom portion of the first ice-filled bag is adjacent to one of the front and back inside walls; and

the bottom portion of the second ice-filled bag is adjacent to the other of the front and back inside walls.

2. The apparatus of claim 1, wherein each of the disposal zones defines a stacking level;

and

wherein the apparatus further comprises;

a processor; and

a computer readable medium operably coupled to the processor, the computer readable medium comprising a plurality of instructions stored therein and executable by at least the processor, the plurality of instructions comprising;

instructions for determining the stacking level of each of the disposal zones; and

instructions for determining the lowest stacking level of the respective stacking levels of the disposal zones.
