Abstract
An ice bagging assembly and related method with a horizontal ice bag cassette, a pair of opposing ice bag ply graspers configured to move an empty ice bag from the horizontal ice bag cassette to a vertical position to receive cubed ice before it is sealed shut and dropped to an ice bag merchandiser. The opposing graspers may be configured as rotating wheels and may have a grasping sensor. The ice bag cassette may be slidably and tiltably supported for easy replacement of horizontal bags. A load sensor, optical or mechanical, may be associated with the ice hopper to sense how much ice has been put in each bag. A pair of angled guides may guide a hopper into a support frame for the system.

DESCRIPTION
(18) This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended operation of an ice bagging assembly and/or assembly procedures for an ice bagging assembly will become apparent from this disclosure. Accordingly, for example, although particular support frames, horizontal ice bag cassettes, bag selectors, plurality of ice bags, first bags, ice chutes, ice bag supports, sealing mechanisms, open ends, ice bag merchandisers, ice cube hoppers, load sensors, angled guides, ice bag cassettes, first plys, second plys, insides of ice bags, opposed grasping elements, first positions, second positions, wheels, horizontal positions, vertical positions, open dimensions, suspension elements, and implementing components are disclosed, such may comprise any shape, size, style, type, model, version, measurement, concentration, material, quantity, and/or the like as is known in the art for such ice bagging assemblies, consistent with the intended operation of an ice bagging assembly.
(19) There are a variety of ice bagging assembly implementations disclosed herein.
(20) In some particular implementations, such as that shown with respect to
(21) As best illustrated in
(22) A bag selector 10 operationally coupled to the support frame 4 is configured to select one or more empty ice bags from the plurality of empty ice bags 8. As illustrated by
(23) In any event, as shown specifically in
(24) In some particular implementations, at least one load sensor 33 may be interposed between the ice cube hopper 24 and the support frame 4 at one or both ends of the ice cube hopper 24. A load sensor 33 (also called a load cell) may be used in conjunction with an ice bagging assembly and/or a hopper 24 in various ways and for various purposes such as, by way of non-limiting example, to assist in determining when an ice cube hopper 24 and/or one or more of the plurality of empty ice bags 8 is full of ice and/or still empty. Specifically, by measuring the amount of load on the load cell 33 when an ice cube hopper 24 is full (thereby establishing a “full-load” measurement), an ice cube maker 52 can be programmed to begin ice production when the load on the load cell 33 corresponds to a less than full load (and/or to stop ice production when the load cell indicates a full ice hopper 24). Similarly, the weight of ice cubes introduced into an ice bag can be determined by measuring a decreasing load on the load cell 33, such that ice cubes are no longer introduced into an ice bag when a load on the load cell 33 has decreased to a pre-determined range. It will be understood that the quantity of ice to be placed in a hopper and/or an ice bag may be measured in other ways such as, by way of non-limiting example, weighing an ice bag and/or using a camera, laser-level, or other optical device to measure the amount of ice in the bag. For example, as illustrated in
(25) Referring specifically to
(26) An ice bag merchandiser 22 (
(27) Referring specifically to
(28) In those particular implementations comprising at least one pair of opposed grasping elements 36, the pair of grasping elements 36 may include at least one first wheel 40 configured to rotate about an axis (the other element of the pair of grasping elements 36 may be movable or stationary, depending upon the particular implementation). In some particular implementations, the at least one pair of grasping elements 36 may include at least two opposed wheels (e.g., at least one first wheel 40 and at least one second wheel 42, as shown in
(29) In yet other particular implementations, the at least one pair of opposed grasping elements 36 may comprise at least two pairs of opposed grasping elements 36, with each pair grasping a different ply of the first ply 30 and the second ply 32 of a first empty ice bag 12. In such particular implementations, the at least one pair of opposed grasping elements 36 each comprise at least one first wheel 40 configured to rotate about an axis. In any event, at least one pair of opposed grasping elements 36 is configured to move away from the second ply 32 of an empty ice bag 12 after grasping the first ply 30, such that the open end 20 of the empty ice bag 12 opens (it will be understood that the second ply 32 may be restrained by a second pair of opposed grasping elements 36, or in another way, such as via one or more suspension elements 50). It will be understood that one or more of the wheels 40 and 42 (and or other portions defining a pair of opposed grasping elements 36) may be formed with, or from, materials having a high co-efficient of friction such as, by way of non-limiting example, textured plastic or metal, or textured or untextured rubber, silicone, or knurled stainless steel. In addition, while the wheels shown and described herein are shown as being round, it will be understand that, in some particular implementations, one or more wheels 40 or 42 may comprise a perimeter or other shape other than round.
(30) Referring to
(31) Depending upon the particular implementation being used, a method of selecting and filling a plurality of empty ice bags 8 from a horizontal ice bag cassette 6 may comprise moving at least one pair of grasping elements 36 into contact with the first ply 30 of the empty ice bag 12 and rotating at least one grasping element (of the at least one pair of grasping elements 36) with respect to the other grasping element of the at least one pair, in order to grasp the first ply 30. In some particular implementations, both grasping elements of the at least one pair of grasping elements 36 may be rotated in opposite directions to grasp the first ply 30.
(32) While some particular implementation of bag selectors 10 may comprise at least two pairs of opposed grasping elements 36, with each pair grasping a different one of the first and second plys, other particular implementations of a bag selector 10 may include one or more suspension elements 50 opposed to at least one pair of opposed grasping elements 36. In those particular implementations of a bag selector 10 having one or more suspension elements 50 opposed to at least one pair of opposed grasping elements 36, a second ply 32 of the empty ice bag 12 may be restrained by passing one or more suspension elements 50 through the second ply 32 of the empty ice bag 12 in the horizontal position. It will be understood that the second ply 32 may include one or more holes or perforations to assist in the passage therethrough of one or more suspension elements 50.
(33) A method of selecting and filling a plurality of empty ice bags 8 from a horizontal ice bag cassette 6 may further include measuring a quantity of ice dropped into the empty ice bag 12 by sensing the weight of the ice cube hopper 24 through a sensor (such as a load sensor) interposed between the ice cube hopper 24 and a support frame 4 for the ice cube hopper, or by other methods described more fully above.
(34) In those particular implementations of a bag selector 10 having a ice bag cassette 6 that is not horizontally-oriented, a method of selecting and filling a plurality of empty ice bags 8 may comprise moving a bag selector 10 from a rest position 43 to a first bag selector position 45 adjacent to an ice bag cassette 6 by moving at least one pair of opposed grasping elements 36 into contact with the first ply 30 of the empty ice bag 12 and rotating at least one grasping element of the at least one pair of opposed grasping elements 36 with respect to the other grasping element of the at least one pair of opposed grasping elements 36 in order to grasp the first ply 30. As with those particular implementations having a horizontally-oriented ice bag cassette, the second ply 32 of the empty ice bag 12 may be restrained such that an open dimension 48 of the open end 20 of the empty ice bag 12 is increased as the one or more opposed grasping elements 36 of the bag selector 10 (that have grasped the first ply 30) move away from the restrained second ply 32. The bag selector 10 is further configured to move away from the horizontal ice bag cassette 6 after grasping the first ply 30 of the empty ice bag 12, such that the bag selector 10 positions the open end 20 of the empty ice bag 12 facing upwardly below an ice chute 14. The method further includes dropping a plurality of ice cubes from the ice chute 14 into the empty ice bag 12, and then sealing the open end 20 of the empty ice bag 12 after dropping the ice cubes into the bag.
(35) Depending upon the particular implementation being used, a method of selecting and filling a plurality of empty ice bags 8 may comprise rotating both grasping elements of the at least one pair of grasping elements 36 in opposite directions to grasp the first ply 30. One or more suspension elements 50 opposed to at least one pair of opposed grasping elements 36 may be passed through the second ply 32 of the empty ice bag 12 such that the second ply 32 is restrained.
(36) Turning now to
