The field of this disclosure relates generally to method and systems for glove dispensing and, in particular, to such methods and systems configured to utilize a glove cartridge.
Sanitary gloves have been an essential item for many industries for decades, including medical industries, food industries, and law enforcement agencies. These gloves can be relatively tight fitting and difficult or time consuming to put on, especially with damp hands that have just been washed. The gloves are often stored in boxes of 50 to 500 gloves, which are easy to contaminate while gloves are pulled from the box for use or for storage in after-market bins. Often only a single size of large gloves is available because the larger gloves are easier to put on and “fit” everyone. People with smaller hands are often compelled to use oversized gloves, which wastes material and may interfere with fine finger control.
Many devices have been made to facilitate and automate hygiene: automated water faucets, automated soap dispensers, automated paper towel dispensers, and automated hand dryers, for example. However, glove donning has not been automated in a practical manner.
One aspect of this disclosure relates to glove cartridges.

Unless otherwise specified, a range of values, when recited, includes both the upper and lower limits of the range, as well as any sub-ranges therebetween. Unless indicated otherwise, terms such as “first,” “second,” etc., are only used to distinguish one element from another. For example, one element could be termed a “first element” and similarly, another element could be termed a “second element,” or vice versa. The section headings used herein are for organizational purposes only and are not to be construed as limiting the subject matter described.
Unless indicated otherwise, the terms “about,” “thereabout,” “substantially,” etc. mean that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art.
Spatially relative terms, such as “right,” left,” “below,” “beneath,” “lower,” “above,” and “upper,” and the like, may be used herein for ease of description to describe one element's or feature's relationship to another element or feature, as illustrated in the drawings. It should be recognized that the spatially relative terms are intended to encompass different orientations in addition to the orientation depicted in the figures. For example, if an object in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can, for example, encompass both an orientation of above and below. An object may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may be interpreted accordingly.
Unless clearly indicated to be otherwise only, all connections and all operative connections may be direct or indirect. Similarly, unless clearly indicated to be otherwise only, all connections and all operative connections may be rigid or non-rigid.
Like numbers refer to like elements throughout. Thus, the same or similar numbers may be described with reference to other drawings even if they are neither mentioned nor described in the corresponding drawing. Also, even elements that are not denoted by reference numbers may be described with reference to other drawings.
Many different forms and embodiments are possible without deviating from the spirit and teachings of this disclosure and so this disclosure should not be construed as limited to the example embodiments set forth herein.
With global outbreaks of deadly contagious diseases becoming more regular, frequent glove changes are required in medical industries, food industries, and law enforcement agencies, for example. A practical glove-dispensing machine would save time and help prevent spread of contagious agents.
The middle region 24 may include a palm part 30 and a back part (not shown) that are configured to cover the palm region of a hand. A thumb part 34 may form part of the middle region 24, the upper region 22, or both the middle region 24 and the upper region 22. The lowest portion of the thumb part 34 may be positioned in the middle region 24 or the upper region 22. The thumb part 34 may have a wider circumference and diameter than those of the finger parts 28, and the thumb part 34 may be shorter than the finger parts 28. However, the thumb part 34 may be longer than or equal to the finger part 28d.
The lower region 26 may include a wrist part 36 and a glove base 38 that defines a glove opening 40. In
The gloves 20 may be configured as a “one size fits all” glove 20, or the gloves 20 may be configured in different sizes, such as: large and small; large, medium, and small; or extra large, large, medium, small, and extra small. The different sizes may include different lengths or circumferences for the finger parts 28, and/or different dimensions for the palm part 30 or the opening 40. The gloves 20 may all have the same color, or different sizes of gloves 20 may be manufactured with different colors so that the different sizes are readily discernable.
The glove opening 40 may be circular, oval, elliptical, or other shape in a relaxed (nonstretched) at least partly open state. Regardless of shape, perimeter and circumference are used interchangeably herein for convenience. In some embodiments, the glove opening 40 for a small glove 20 may have a perimeter of 200 mm plus or minus 5 mm, the glove opening 40 for a medium glove 20 may have a perimeter of 210 mm plus or minus 5 mm, and the glove opening 40 for a large or an extra large glove 20 may have a perimeter of 220 mm plus or minus 5 mm.
The glove base 38 or the glove opening 40 may have a major opening dimension 32 along a major opening axis 44 and a minor opening dimension 46 along a minor opening axis 88. The major opening axis 44 may be generally parallel with a major plane of the middle region 24 or palm part 30. These dimensions will vary depending on whether the glove is in a stretched state or a relaxed state. In a relaxed state, the major opening axis 44 may be an inverse function of the minor opening dimension 46 and vice versa. However, these axes and dimensions may be useful for describing orientation.
The cartridge frame boundary 56 may have any shape, such as elliptical, oval, circular, or polygonal. Possible polygonal shapes for the cartridge frame boundary 56 may include, but are not limited to, rectangular, square, pentagonal, hexagonal, octagonal, or dodecagonal. The polygon may include one side or pair of sides that are dissimilar from other sides in shape or length so as to facilitate handling of the glove cartridge 50 in a dedicated orientation. For example, the cartridge frame boundary 56 may have a top side 72 that has a top dimension 74 that is greater than or equal to a side dimension of a left or right side 78. One will appreciate that the shape of the cartridge frame boundary 56 (and/or the dimensions of its sides) may be useful for error-proofing that the cartridges 52 are oriented correctly when placed into holding chambers 122 (
Similarly, the aperture inner edge 60 may have any shape, such as elliptical, oval, circular, or polygonal. Possible polygonal shapes for the aperture inner edge 60 may include, but are not limited to, rectangular, square, pentagonal, hexagonal, octagonal, or dodecagonal. The aperture 58 may have a major aperture dimension 80 along a major aperture axis 82 that propagates through the central axis 70, and the aperture 58 may have a minor aperture dimension 84 along a minor aperture axis 86 that propagates through the central axis 70. The major aperture axis 82 and the minor aperture axis 86 are typically transverse and may be perpendicular. The major aperture axis 82 may bisect the top side 72 and the bottom side, and the minor aperture axis 86 may bisect the left and right sides 78. However, alternative major aperture axes 82 may run through opposite corners.
In some embodiments, a small cartridge aperture 58 may have a perimeter that is 38% plus or minus 5% larger than a small glove opening 40. In one example, a small cartridge aperture 58 may have a perimeter that is 277 mm plus or minus 14 mm. In some embodiments, a medium cartridge aperture 58 may have a perimeter that is 39% plus or minus 5% larger than a medium glove opening 40. In one example, a medium cartridge aperture 58 may have a perimeter that is 294 mm plus or minus 15 mm. In some embodiments, a large or extra large cartridge aperture 58 may have a perimeter that is 50% plus or minus 5% larger than a large or extra large glove opening 40. In one example, a large or extra large cartridge aperture 58 may have a perimeter that is 331 mm plus or minus 16.5 mm.
The aperture dimensions may be based on the glove size and glove material and may also be brand dependent. In some embodiments, the major aperture dimension 80 may be approximately 40-50% larger than the glove opening 40. A determinate factor for aperture size may be elasticity of the glove 20 being mounted to the cartridge 52. The aperture dimensions may be tuned to fit a certain brand of the glove 20 in a manner that permits the glove base 38 or glove lip 42 to be mounted without over-stretching it, while the glove base 38 or glove lip 42 provides sufficient elastic force to stay on the cartridge 52 until the hand 190 (
In some embodiments, the cartridges 52 may all have the same shape and size for the cartridge frame boundary 56 regardless of whether the cartridges 52 support different sizes of gloves 20. In such embodiments, the cartridge apertures 58 may have different sizes or shapes to accommodate the potentially different sizes of the perimeters of the glove bases 38, if useful. The cartridge apertures 58 of different sizes may provide a useful visual cue for distinguishing the different sizes of gloves 20 carried by the cartridges 52. One will appreciate, however, that the cartridges 58 supporting different sizes of gloves 20 may have cartridge apertures 58 of identical sizes and shapes as well as frame boundaries 56 of identical sizes and shapes. The flexibility or stretchability of the glove material may permit such uniformity of the cartridges 52.
In some of such embodiments, the cartridges 52 may have different signature colors for each glove size and/or the gloves 20 may have different signature colors for each glove size, as previously mentioned, as a useful visual cue for distinguishing the different sizes of gloves 20 carried by the cartridges 52. The signature coloring may cover all or parts of the cartridge 50, such as one or both major surfaces 48 (front major surface 48a and back major surface 48b) of the cartridge 50.
Alternatively, the cartridges 52 may have a different shape and/or size for the cartridge frame boundary 56 for different sizes of gloves 20. For example, the cartridges 52 may be configured with decreasing sizes to coordinate with decreasing sizes of gloves 20. Alternatively or additionally, the frame boundaries 56 of the cartridges 52 may be configured with different numbers of sides to coordinate with the sizes of gloves. For example, a cartridge 52 for a large glove 20 may be configured with eight sides; a cartridge 52 for a medium glove 20 may be configured with six sides; and a cartridge 52 for a small glove 20 may be configured with four sides.
In some embodiments, the cartridge 52 has a major axis (along a side or along a diagonal) that is less than or equal to 155 mm (6 inches). In some examples of rectangular frame boundaries 56, the frame boundary dimensions are 101.6 mm plus or minus 25 mm by 127 mm plus or minus 25 mm. In some examples of rectangular frame boundaries, at least two of the frame boundary dimensions differ by greater than 10 mm, 15 mm, or 25 mm. Cartridges 52 with different shapes or with different dimensions along different sides may be useful to ensure placement of respective different cartridges 52 into respective holding chambers 122 and/or may be useful to ensure that the cartridges 52 are placed into the holding chambers 122 in a desirable orientation.
With or without different cartridge configurations, the cartridges 52 may be color coded to reflect different glove sizes. One will appreciate, however, that having uniform sizes or similar shapes (such as rectangles of the same or different sizes) for cartridge frame boundaries 56 regardless of different glove sizes may simplify considerations for a glove-dispensing machine, as later described. The cartridges 52 may also include alternative keying features, such as one or more notches or outward tabs along one or more of the sides of the frame boundaries 56 that are matched to particular holding chambers 122 and/or particular orientations within the holding chambers 122, to facilitate placement of specific cartridge types into specific holding chambers 122 in specific orientations. Moreover, cartridges 52, especially cartridges 52 having identical frame boundary dimensions but supporting different-sized gloves 20, may be equipped with machine-identifiable size information. Machine sensors may be employed to identify size or other information by cartridge color or by sensing RFID tags that contain desirable information such as size.
An aperture ridge 62 may be in proximity to the aperture inner edge 60 and may extend along at least a portion of the aperture edge 60. Proximity to aperture inner edge 60 may be less than or equal to 1 cm, less than or equal to 0.5 cm, or less than or equal to 0.25 cm, or may be at the aperture inner edge 60, itself. In
The aperture ridge 62 may extend along the entire perimeter of the aperture edge 60. However, the aperture ridge 62 may extend along only a major portion of the aperture edge 60 (i.e., greater than or equal to half the perimeter of the aperture edge 60), or the aperture ridge 62 may extend along a minor portion of the aperture edge 60 (i.e., less than or equal to half the perimeter of the aperture edge 60). The aperture ridge 62 may be a continuous structure, or it may be a discontinuous structure, including one or more breaks along the aperture edge 60, forming multiple aperture tabs 62a. Moreover, the aperture ridge 62 may have a uniform cross-sectional profile along its length, or the aperture ridge 62 may have a nonuniform cross-sectional profile along its length, with regions having different cross-sectional profiles or sizes. A discontinuous aperture ridge 62 (aperture tabs 62a) may permit less force to be applied to disconnect a glove 20, facilitating easier glove removal by an inserted hand 190. Accordingly, the amount of the aperture ridge 62 along the aperture edge 60 may be configured to the specific size, elasticity, and/or brand of the glove 20.
The aperture ridge 62 may have a ridge base 64 and an optional ridge lip 66, wherein the aperture inner edge 60 is closer to the ridge base 64 than to the ridge lip 66. The ridge base 64 may have a base perimeter that is smaller than a lip perimeter of the ridge lip 66, potentially forming a recess 68 between the ridge lip 66 and a major surface 48 of the cartridge 52. For example, the aperture ridge 62 may flare outwardly (with respect to a central axis 70 of the cartridge aperture 58) from the ridge base 64 to the ridge lip 66. In another example, the ridge base 64 may extend generally perpendicularly from the plane of the cartridge aperture 58, and the ridge lip 66 may extend outwardly (with respect to the central axis 70 of the cartridge aperture 58) from the ridge base 64. The ridge lip 66 may be transverse to the ridge base 64, extending toward or away from the plane of the aperture 58 or generally perpendicular to the plane of the aperture 58.
The aperture ridge 62 could alternatively flare inwardly. A perpendicular or inward flare would decrease complexity in a cartridge injection mold design, as such ridges 62 would allow the use of a simple two-piece mold. An outward flare might utilize additional mold slides to form the underlying recess. However, cartridges may be manufactured by on-demand printing that could readily accommodate any design features.
The ridge base 64 or ridge lip 66 may be continuous structures, or they may be discontinuous structures, including one or more breaks along the aperture edge 60. One will appreciate that their continuities need not be the same. Moreover, they may have uniform cross-sectional profiles along their lengths, or they may have nonuniform cross-sectional profiles along their lengths, with regions having different cross-sectional profiles or sizes. The dimensions of the ridge base 64 or ridge lip 66 may be configured to the specific size, elasticity, brand of the glove 20, and/or the amount of the aperture ridge 62 along the aperture edge 60.
The major cartridge surface 48 may have surface area that includes all of the area between the cartridge frame boundary 56 and the cartridge aperture 58. Alternatively, the major cartridge surface 48 may be skeletal in nature having sufficient struts or other connections between the cartridge frame boundary 56 and the cartridge aperture 58 to sustain structural integrity. The cartridge surface 48, itself, may be flat or textured. There may, however, be air-pressure-containment advantages or hygienic or sterilization advantages for having a flat, uniform, continuous surface between the cartridge frame boundary 56 and the cartridge aperture 58. The cartridge surface 48 may employ a transparent, semi-transparent, or translucent material, or may include one or more windows of such materials. Even so, color coding of the cartridges would still be possible.
In some embodiments, the major cartridge surface 48 exhibits no slope from the cartridge frame boundary 56 to the cartridge aperture 58, such that the cartridge frame boundary 56 and the cartridge aperture 58 lie in the same plane. In some embodiments, the major cartridge surface 48 slopes from the cartridge frame boundary 56 to the cartridge aperture 58 so that the cartridge frame boundary 56 and the cartridge aperture 58 lie in different planes. The slope can be forwardly or backwardly with respect to the front cartridge surface 48a. A sloped surface 48 may be advantageous for providing space for the glove 20 when it is in a collapsed configuration 92, which is shown in
The cartridge 52, at or near the cartridge frame boundary 56, may have a boundary wall 90 (
One will appreciate that an outward flare may facilitate stacking the cartridges on top of each other with their surface planes being substantially parallel. The outward taper of the boundary wall 90 may extend from the front cartridge surface 48a as shown in
However, many embodiments that do include a boundary wall 90 have it only on one side of the cartridge 52 so that the cartridge 52 can present a flat surface to a back surface 176 of a glove portal face 178, as later described with respect to
The glove 20 may be seated on the cartridge 52 in a number of ways. The glove base 38, with or without, a glove lip 42 may be positioned around the aperture ridge 62. In particular, the glove base 38 or glove lip 42 may be positioned at the ridge base 64, or between the ridge base 64 and the ridge lip 66, such that the glove base 38 and the glove opening 40 are positioned about the cartridge aperture 58 in a stretched condition 100 with the interior of the glove 20 facing frontwards with respect to the front major surface 48a of the cartridge 52 (regardless of whether the aperture ridge is positioned on the front major surface 48a or on the rear major surface 48b).
The glove 20 may be oriented to the cartridge 52 so that its major opening axis 44 is generally collinear with, or generally parallel with the major aperture axis 82 of the cartridge 52. For example, the major opening axis 44 of the glove 20 may be generally collinear or generally parallel with a major aperture axis 82 that bisects the top side 72 and bottom side of the cartridge 52, or the major opening axis 44 of the glove 20 may be generally collinear or generally parallel with a major aperture axis 82 that runs through the corners of the cartridge 52. One will, however, appreciate that the major opening axis 44 may be positioned with other orientations with respect to the cartridge 52. For example, the major opening axis 44 may be oriented at a glove-orientation angle with respect to the major aperture axis 82 that bisects the top side 72 and bottom side of the cartridge 52. However, the glove-orientation angle may be less than or equal to 45 degrees, less than or equal to 30 degrees, less than or equal to 25 degrees, less than or equal to 15 degrees, less than or equal to 10 degrees, or less than or equal to 5 degrees.
In some embodiments, one or both faces of the glove cartridge 50 may be hermetically sealed or partly sealed such as by a wrap or film 110. The film 110 may help maintain the glove 20 in the collapsed configuration 92 during transport, storage, and manipulation of the glove cartridge 50. The film 110 may be a plastic or other layer material and may be configured with indentations or perforations along predetermined tear lines 112. In one embodiment shown in
Film 110 may be transparent as shown in
In some embodiments, the glove cartridge 50 may include an additional cartridge aperture 58 that may have any of features previously discussed and that may support an additional flexible glove 20 having any of features previously discussed. In such embodiments, the major cartridge surface 48 may be substantially planar, or it may be angled between the two glove apertures 58. The angle between the planes may be between two axes or between three axes.
The holding chambers 122 may have chamber doors 124 (with or without handles 108) that swing outwardly from holding chamber side walls 116 on one or more pivot points such as hinges 118. One will appreciate that other door configurations are possible, such as doors 124 that open upwardly to bias a closed-door position. Alternatively, hinges 118 can be biased to close a horizontal swing, for example. In some embodiments, the doors 124 may be configured to slide horizontally to avoid possible contamination caused by air being swept toward the chamber 122 when the door 124 is swinging closed. In other additional or alternative embodiments, the chambers 122 can be supplied with positive air pressure to prevent or inhibit external air from entering the chambers 124.
Some embodiments of the glove-dispensing machine 120 may omit chamber doors 124. As shown in
The doors 124 may be marked to indicate a specific glove size to facilitate the loading of the correct glove cartridges into the correct chambers 122. These indicators may include words, initials, and/or colors that designate specific sizes. The holding chambers 122 may be associated with or correspond to size selector mechanisms 126 on a size selector panel 128. For example, the holding chambers 122a, 122b, and 122c may correspond to size selector mechanisms 126c, 126b, and 126a, respectively. The size selector mechanisms 126 may include, push buttons, (re-settable) switches, pull knobs, or other equivalents.
With reference to
However, the glove-dispensing system 130 may include two glove-dispensing machines 120 that are mirror images of each other. However, in some embodiments, some of the components and mechanisms may be mirror images and other components and mechanisms that need not be oriented to a particular side can be substantially similar or substantially identical. One will also appreciate that any portion of the description concerning the glove-dispensing system 130 may also apply to the glove-dispensing machine 120, except where such descriptions can pertain only to a glove-dispensing system 130 that includes two or more glove-dispensing machines 120.
The glove-dispensing system 130 may also include a central spacer portion whose purpose is to space apart the two glove-dispensing machines 120 by a suitable distance to allow a user to don a glove 20 on each hand substantially simultaneously. In some embodiments, the glove-dispensing system 130 may include two size selector panels 128, one for each glove-dispensing machine 120 to accommodate people who have hands of different sizes. However, the glove-dispensing system 130 may include only a single size selector panel 128 to provide gloves 20 of the same size at each glove portal 150. Moreover, for a two-hand glove-dispensing system 130, a number of components may be centralized, such as a main controller and/or a vacuum pump, for example, as later described. Also, the space between the mirrored machines 120 (or partly mirrored machines 120) may be used to house components, allowing the over system size to be smaller.
With reference to
One will appreciate that the cartridge deck actuator 152 may alternatively be employed to move the glove cartridge 50 off the top of a stack of glove cartridges 50. Optical or other sensing systems may be used to determine the position of the top glove cartridge 50, or the entire stack may be sensed and moved to position the top glove cartridge 50 in line with the actuator. Moreover, the glove cartridges 50 may be stored vertically side by side, and the cartridge deck actuator 152 may be oriented appropriately.
The upper pathway chambers 146a and 146b may each include one or more cartridge slides 160 that permit the glove cartridges 50 to be directed by gravity onto the sealing plate 158. In this regard, the cartridge slides 160 may be configured with slopes that are steep enough to permit gravity to move the glove cartridges 50 on to the sealing plate 158. The cartridge slides 160 may all be angled in the same direction and at the same slopes, or they may be angled in different directions and/or at different angles. For example, an upper slide 160 may be configured to deliver the glove cartridge 50 at least partly onto or into contact with a lower slide 160.
The slide angles may be configured to retain the glove cartridge 50 in its as loaded (in the holding chamber) face up or face down (or sideways) configuration and its original orientation with respect to its major aperture axis 86. Alternatively, the arrangement of the cartridge slides 160 can be configured to flip and/or rotate the glove cartridge 50 one or more times between the holding chamber 122 and the sealing plate 158.
In some embodiments, a single cartridge deck actuator 152 may be employed to serve all of the holding chambers 122 or each glove-dispensing machine 120. In yet other embodiments, a centralized cartridge moving mechanism can be employed to move the glove cartridges 50 from all of the holding chambers 122 of the glove-dispensing machines 120 on both sides of the glove-dispensing system 130. Such a centralized system may employ a cartridge extraction mechanism utilizing vacuum or other conveyance system.
One will appreciate that the glove cartridges 50 have some similarities in size and shape to computer discs and that automated transport and manipulation of computer discs during their manufacture and use are well known. U.S. Pat. No. 5,335,218, the disclosure of which is incorporated herein by reference, provides a suitable example of how discs can be loaded and conveyed between different locations. The glove-dispensing system 130 need not being wedded to this particular conveying system. However, one can utilize any known disc conveyance technique to move a glove cartridge 50 from its holding chamber 122 to the sealing plate 158. For convenience, the route that the glove cartridges 50 take between the holding chamber 122 and the sealing plate 158 may be called a cartridge path or cartridge pathway.
The sealing plate 158 may be positioned within the lower housing potion 138 and may be angled away from the glove portal 150 such that a bottom 170 of a front surface 172 of the sealing plate 158 is in proximity to a bottom 174 of a rear surface 176 of a glove portal face 178 of the glove portal 150. The bottom 170 and the bottom 174 may be spaced apart when receiving a glove cartridge 50, and a retaining system or device 180, such as a cartridge retaining solenoid or other gate or switch, may be employed to prevent the glove cartridge 50 from passing in between. The retaining device 180 effectively stops the glove cartridge 50 in front of the glove portal 150 of the vacuum chamber 202 and may be configured or programmed to allow the glove cartridge 50 to drop below once the glove 20 has been removed from the glove cartridge 52.
The sealing plate 158 may have a sealing plate aperture 182, and the sealing plate 158 and sealing plate aperture 182 may have any shapes, such as elliptical, oval, circular, or polygonal. Possible polygonal shapes may include, but are not limited to, rectangular, square, pentagonal, hexagonal, octagonal, or dodecagonal. The shapes do not have to correspond; however, the perimeter of the sealing plate 158 will be greater than the perimeter of the sealing plate aperture 182.
The sealing plate aperture 182 may have a major aperture dimension along a major aperture axis that is greater than or equal to the major aperture dimension 80 of the cartridge 52 so that the sealing plate does impede a hand 190 (
Similarly, the glove portal face 178 and the glove portal 150 may have any shapes, such as elliptical, oval, circular, or polygonal. Possible polygonal shapes may include, but are not limited to, rectangular, square, pentagonal, hexagonal, octagonal, or dodecagonal. The shapes do not have to correspond; however, the perimeter of the glove portal face 178 will be greater than the perimeter of the glove portal 150. The glove portal face 178 may employ a transparent, semi-transparent, or translucent material, or may include one or more windows of such materials. Such embodiments would permit a user to see the gloves 20 beyond the glove portal face 178. Visual confirmation that the gloves are in a spread out or hand-receiving configuration, as later discussed, may be useful.
The glove portal 150 may have a major aperture dimension 192 along a major aperture axis 194 and a minor aperture axis 196, wherein the major aperture axis 194 is greater than or equal to the major aperture dimension of the sealing plate 158 so that the glove portal face 178 cannot impede a hand 190 from reaching through the sealing plate 158. However, one will appreciate that the major aperture dimension 192 of the glove portal 150 may be smaller than the major aperture dimension of the sealing plate 158. The major axis 194 of the sealing plate aperture 182 may be aligned to that of sealing plate aperture 182, or they may have different alignments.
In many embodiments, the cartridge aperture 58 is smaller than or equal to the glove portal 150 and smaller than or equal to the sealing plate 158. In particular, the major aperture dimension 80 of the cartridge aperture 58 may be smaller than or equal to the major aperture dimension 192 of the glove portal 150 and smaller than or equal to the major aperture dimension sealing plate 158.
Based on its selected orientation in the holding chamber 122, the glove cartridge 50 may be conveyed step by step to the sealing plate 158 in a known desirable orientation. Alternatively, edge or boundary configurations or features on the glove cartridge 50 can be physically or optically analyzed so that the orientation of the glove cartridge 50 can be manipulated or corrected at or before reaching the sealing plate 158. In some embodiments, the glove cartridge 50 may be oriented so that the thumb is toward the top of the glove portal 150 such as aligned with vertical axis. For example, as previously mentioned, the major opening axis 44 of the glove 20 may be aligned with the major aperture axis of the cartridge 52. However, the glove cartridge 50 may be oriented so that the thumb of the glove is offset from the vertical axis, in which case either or both of the major opening axis 44 of the glove 20 and the major aperture axis of the cartridge 52 may be offset with respect to the vertical axis (and may be offset with respect to each other at a glove-orientation angle as previously described).
After the glove cartridge 50 is moved from the holding chamber 122 and seated on the sealing plate 158, a sealing plate actuator 200 may be employed to press the glove cartridge 50 against a front surface (such as the back surface 176 of the glove portal face) of a vacuum chamber 202 that may be, or include part of, the lower housing portion 138.
In one embodiment, the sealing plate actuator 200 employs a sealing plate actuator motor 198 that utilizes a ball-screw assembly. In particular, the sealing plate actuator motor 198 may have a ball screw 206 attached to it which, when spun, causes a ball nut 208 to move along the ball screw 206. The ball nut 208 may be connected to a drive arm 210 that may be connected to the sealing plate 158 such that spinning of the motor 198 causes movement of the sealing plate. The drive arm 210 may be straight, bent, or curved and the connections may be immobile or pivoted such as through one or more pivot assemblies 212. One will appreciate, however, that the sealing plate actuator 200 could be a cam-operated system, mechanical-path system, or any type of other actuation system.
The seal established by the force of the sealing plate actuator 200 between the glove cartridge 50 and the back surface 176 may be substantially airtight and/or hermetic. An O-ring seal may be used, such as with an O-ring on each side of the cartridge. Alternatively or additionally, O-ring gaskets may be positioned around on one or more of the sealing plate aperture 182 on the sealing plate 158 and the glove portal 150 on the back surface 176 of the glove portal face 178. A flexible sealing membrane that seals between the cartridge sealing plate 158 and vacuum chamber 202 may alternatively or additionally be employed. Such a flexible membrane would allow the sealing plate 158 to move relative to the vacuum chamber 202 during cartridge loading. In other embodiments, the flat major surface 48 of the cartridge 52 may directly contact the back surface 176 of the glove portal face 178 without a gasket.
The aperture ridge 62 of the cartridge 52 generally has a height that is greater than the thickness of the cartridge 52. So, if the aperture ridge 62 of the cartridge 52 faces away from the sealing plate 158, then the aperture ridge 62 may protrude through the glove portal 150. If the aperture ridge 62 of the cartridge 52 faces toward the sealing plate 158, then the aperture ridge 62 may protrude through the sealing plate aperture 182.
One will appreciate that a glove-dispensing system 130 employing two glove-dispensing machines 120 may provide the glove portal faces 178 of both machines 120 so that they lie along the same plane. However, the planes of the glove portal faces 178 of the two machines 120 may be angled with respect to each other. Moreover, these angles may lie along two axes or three axes. One will also appreciate that the cartridges 52 may be positioned over the two glove portals so that the major opening axes 44 of the gloves 20 are substantially parallel. However, the cartridges 52 may be positioned over the two glove portals so that the major opening axes 44 of the gloves 20 are at an angle. In such embodiments, selected side edges of the two cartridge frame boundaries 56 may be parallel with the major opening axes 44 at angles with respect to the major aperture axes 82 of the cartridges 52 and with respect to each other. However, the major opening axes 44 may be parallel or colinear with the major aperture axes 82 of the cartridges 52, and the selected side edges of the two cartridge frame boundaries 56 may be positioned at an angle to each other.
The vacuum chamber 202 may be connected directly or indirectly to a vacuum source 204 to create a vacuum pressure within the vacuum chamber 202. The vacuum source 204 may be automated to turn on after the vacuum chamber 202 is sealed. The vacuum pressure is set at a level sufficient to pull the upper region 22, the middle region 24, and the lower region 26 of the glove 20 away from the glove portal 150, effectively spreading open the tubes of the finger parts 28, palm part 30, thumb part 34, and wrist part 36 without disconnecting the glove base 38 from the aperture ridge 62. The vacuum pressure effectively causes the glove 20 to assume a spread out or hand-receiving configuration that facilitates placement of a hand 190 into the glove 20 as later described. One will appreciate that the vacuum pressure may also be sufficient to break any tear lines 112 that would otherwise prevent the glove 20 from expanding.
One will also appreciate that the vacuum chamber 202 may be capable of containing positive pressure as well as vacuum pressure. The vacuum source 204 may have a reversible capability to provide the vacuum chamber 202 with positive pressure, or the glove-dispensing machine may include a separate positive pressure source as well as a vacuum source 204.
Once the hand 190 is inserted into the glove 22, the pressure in the vacuum chamber 202 may be changed from a vacuum pressure to positive pressure. Positive pressure may help force the glove 20 onto the inserted hand 190 and may also help disconnect (“pop”) the glove base 38 off of the aperture ridge 62. A pressure sensor may be used to regulate the chamber vacuum/pressure. Pressure employed in the vacuum chamber 202 may depend on a variety of variables including, but not limited to, the sizes (or relative sizes) of the cartridge aperture 58 and the glove portal 150 and the material and elasticity of the gloves 20. Pressure may be in the range of +/−14 kPa (2 psi), +/−7 kPa (1 psi), +/−3.5 kPa (0.5 psi), or +/−1.7 kPa (0.25 psi). Many embodiments utilize the +/−3.5 kPa (0.5 psi) range.
After the glove 20 has been removed from the glove cartridge 50, the empty cartridge 52 can be discarded through a bottom of the vacuum chamber 202 and collected in a bin that may be positioned in the base 140 beneath and/or in front of the lower housing portion 138. One or more sensors may establish that the glove 20 has been removed from the cartridge 52 and communicate directly or indirectly (such as through a central controller) with a vacuum controller to turn off the vacuum source 204 or reverse the flow to create positive pressure in the vacuum chamber to reduce or prevent outside air from coming into the vacuum chamber 202.
After removal of the vacuum pressure or the creation of positive pressure, the sealing plate actuator 200 may be instructed to eliminate force against the empty cartridge 52 and return to a relaxed, receiving configuration. Then, the retaining device 180 may be instructed to permit the empty cartridge 52 to pass through the gateway and fall into the bin. The cartridge disposal bin may be integrated into the glove-dispensing system 130 or be a separate standard bin. Finally, the retaining device 180 closes the gateway, and the sealing plate 158 is ready to receive a new glove cartridge 50, when a glove size is selected. One will appreciate that the cartridge removal steps can be conducted after a glove size is selected; however, to improve throughput, one will appreciate that it may be preferable to have the sealing plate 158 in a ready to receive state as the standby state.
With reference to
After the hand 190 is inserted into the glove 20 to the depth and fit of a user's satisfaction, the user can use a twist of the hand or arm to release the glove base 38 from the aperture ridge 62, which consequently releases the glove 20 from the glove cartridge 50. With respect to hand movements, an easy movement is to go from a thumb-up direction and rotating the hands inward (anatomical internal rotation) so the thumbs are pointing at each other. Then pulling the hands outward (away from the system 130). Accordingly, the glove-dispensing system 130 may be configured to orient the glove cartridge 50 at the back surface 176 of the glove portal face 178 (or on the sealing plate 158) so that the thumb is toward the top.
One or more sensors, as previously described, can shut the vacuum (and supply positive pressure) so that the hand 190 bearing the glove 20 can be extracted from the glove-dispensing system 130. Alternatively, as previously discussed, positive pressure may be employed earlier to help force the glove 22 onto the inserted hand 190 and help disconnect the glove base 38 from of the aperture ridge 62. In some embodiments, a slight twist of the hand 190, combined with the positive pressure in the chamber, allows for the glove 20 to be removed from the cartridge 52 with ease. One will also appreciate that positive pressure may be employed to disconnect the glove base 38 from of the aperture ridge 62 without any assistance from the hand 190. One will appreciate that two glove-dispensing machines 120 can operate to provide gloves 20 to two hands simultaneously or sequentially. One will appreciate that a single glove-dispensing machine 120 can operate to provide gloves 20 to two hands sequentially, or that two adjacent single glove-dispensing machines 120 can operate to provide gloves 20 to two hands sequentially simultaneously or sequentially.

With reference again to
In some embodiments, a glove-dispensing machine 120 may be configured with two glove portals 150 that are spaced close to each other, and any of the previously described components can be configured to store and convey glove cartridges 50 that have two cartridge apertures 58, each supporting a glove 20. Alternatively, the glove-dispensing machine 120 may be configured with single larger glove portal 150 that is large enough to accommodate two hands 190.
With reference to
The cartridge deck actuators 152 may also be controlled by the circuitry 236. Proximity sensors, such as, limit switches 250, may be employed at the end of travel for each control motor, such as the cartridge deck actuator motors 148, to detect when desired movement, such as distance of travel, has been completed. Sensors may also be employed to detect that the actuation of cartridge through the glove-dispensing machine 120 has been completed successfully, including loading and unloading from in front of the vacuum chamber 202.
A detection mechanism may be employed to make sure that the correct size glove cartridge 50 has been loaded in front of the vacuum chamber 202 to warn the user and/or eject the cartridge 50 if it is not the size selected. As noted earlier, the glove cartridges 50 may include indicia, such as RFID tags, that can easily convey size and other information about the gloves 20 or cartridges 50.
Other motors, such as for the vacuum source 204, may also be controlled by the circuitry 236. The vacuum source 204, such as a blower motor 244, used to generate vacuum may be variable speed and may be controlled using a closed-loop system with a pressure sensor 242 mounted inside the vacuum chamber 202 for the feedback.
A detection method may be employed for safety purposes to determine whether a hand 190 has been inserted, so the glove-dispensing machine 120 does not actuate in an unsafe way while the hand 190 is inside it. Moreover, sensors may also be employed to detect when the user has inserted their hand(s) 190 into the glove(s) 20, either independently or collectively, which may trigger an automatic reversal of vacuum into pressure to help remove the glove base(s) 38 from the aperture ridges(s) 62. Moreover, an air switch, such as a valve motor 246, may be employed to change the direction of airflow, to either build up vacuum in the vacuum chamber 202 to inflate the glove(s) 20, or to reverse the blower motor 244 and/or release the pressure to force the glove base(s) 38 from the aperture ridges(s) 62 of the glove cartridge(s) 50 once the hand or hands 190 are inserted.
The manual-feed cartridge slot 216 may be optionally included in a machine 120 or system 130 that includes the automated feeding mechanism and/or storage chambers 122. The manual-feed cartridge slot 216 may permit a user to insert atypical sizes or specialized gloves 20 that are not dispersed by from the storage chambers 122 by the automated cartridge-feeding system. Sensors could be employed to indicate to the automated cartridge-feeding system that a glove cartridge 50 is already loaded so that the system does not try to provide an extra cartridge 50. The manual-feed cartridge slot 216 could also be employed if any of the cartridge deck actuators 152 are malfunctioning.
The bottom-dispensing frame 222 may include one or more bottom-dispensing cartridge slots 232. The glove cartridges 50 may be manually dispensed through the slots 232. In some embodiments, the glove cartridges 50 are spring loaded into cartridge boxes 230 to deliver the cartridges downward and/or outward such as via a manual switch or button. Alternatively or additionally, the bottom-dispensing frame 222 may be spring loaded to deliver the glove cartridges 50 outwardly in response to a manual button or switch. The bottom-dispensing frame 222 may be configured for wall mounting, for mounting on the machine 120 or system 130, or for resting on a surface.
