DETAILED DESCRIPTION OF EXAMPLE EMBODIMENT

Some detailed example embodiment are disclosed herein. However, specific structural and functional details disclosed herein are merely representative for purposes of describing example embodiment. Example embodiment may, however, be embodied in many alternate forms and should not be construed as limited to only the example embodiment set forth herein.

Accordingly, while example embodiment are capable of various modifications and alternative forms, example embodiment thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit example embodiment to the particular forms disclosed, but to the contrary, example embodiment are to cover all modifications, equivalents, and alternatives falling within the scope of example embodiment. Like numbers refer to like elements throughout the description of the figures.

It should be understood that when an element or layer is referred to as being “on,” “connected to,” “coupled to,” or “covering” another element or layer, it may be directly on, connected to, coupled to, or covering the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout the specification. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

It should be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, regions, layers and/or sections, these elements, regions, layers, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, region, layer, or section from another region, layer, or section. Thus, a first element, region, layer, or section discussed below could be termed a second element, region, layer, or section without departing from the teachings of example embodiment.

Spatially relative terms (e.g., “beneath,” “below,” “lower,” “above,” “upper,” and the like) may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device 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 term “below” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing various example embodiment only and is not intended to be limiting of example embodiment. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, and/or elements, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements and/or groups thereof.

Thus, example embodiment should not be construed as limited to the shapes of regions illustrated herein but are to include deviations and variations in shapes.

When the words “about” and “substantially” are used in this specification in connection with a numerical value, it is intended that the associated numerical value include a tolerance of ±10% around the stated numerical value, unless otherwise explicitly defined. Moreover, when the terms “generally” or “substantially” are used in connection with geometric shapes, it is intended that precision of the geometric shape is not required but that latitude for the shape is within the scope of the disclosure. Furthermore, regardless of whether numerical values or shapes are modified as “about,” “generally,” or “substantially,” it will be understood that these values and shapes should be construed as including a manufacturing or operational tolerance (e.g., ±10%) around the stated numerical values or shapes.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiment belong. It will be further understood that terms, including those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

A signal from the seventh sensor is configured to indicate whether any product is outside of the container (e.g., pinched between the container and the lid).

In at least one example embodiment, the second inspection portion 2102 is configured to transfer containers that fail the second inspection to the reject bin 2104 or another reject bin (see, e.g., reject bin 2234 of FIG. 22A). In at least one example embodiment, the second inspection portion 2102 includes one or more third air nozzles (see, e.g., air nozzle 2230 of FIG. 22A) configured to direct containers that fail the second inspection to the reject bin 2104 or the other reject bin.

FIGS. 22A-22B depict another inspection station according to various aspects of the present disclosure. FIG. 22A is a partial perspective view. FIG. 22B is a partial top view with a housing removed.

In at least one example embodiment, as shown in FIG. 22A, an inspection station 2200 (e.g., a second inspection portion) includes an exit conveyor 2202 and a first sensor 2204. The first sensor may be coupled to a sensor support 2206. The sensor support 2206 may define a passage 2208 through which a container is configured to be conveyed. The sensor support 2206 may facilitate positioning of the first sensor 2204 about the container.

The first sensor 2204 may be configured to detect when at least a portion of the product is outside of the container (e.g., stuck between a container base and lid). More particularly, a signal from the first sensor 2204 may indicate whether any portion of the container including the product exceeds a predetermined perimeter. If so, product may not be fully enclosed in the container. In at least some example embodiments, the first sensor 2204 is a smart sensor configured to capture an image of the container. The first sensor 2204 may include a camera. The first sensor 2204 may be configured to have a field of view 2210.

In at least one example embodiment, the inspection system 2200 may further include a second sensor 2212. The second sensor 2212 may include a transmitter 2212A and a receiver (not shown). A signal from the second sensor 2212 may indicate whether a container is present and in range (e.g., within the field of view 2210) of the first sensor 2204.

The second sensor 2212 may be a light sensor, such as a fiber-optic sensor, a laser sensor, a photoelectric sensor, a color sensor, another type of light sensor, a non-light sensor, or any combination thereof. The transmitters 2212A is configured to emit light. In at least one example embodiment, the light may be emitted as a beam. All or a portion of the light not being received at the receiver may indicate that the light is being blocked by a container, and therefore, that the container may be in place in range of the first sensor 2204.

In at least one example embodiment, the inspection system may further include a container spacing assembly 2220. The container spacing assembly 2220 may include a housing 2222 through which containers on the exit conveyor 2202 are configured to pass.

In at least one example embodiment, as shown in FIG. 22B, the container spacing assembly 2220 may include a pair of regulating wheels 2224. The regulating wheels 2224 may be spaced apart from one another to define a passage 2226. The regulating wheels 2224 may be configured to ensure a desired (or alternatively, predetermined) spacing between containers upstream of the first sensor 2204 (FIG. 22A). In at least one example embodiment, the regulating wheels 2224 are configured to move a slower linear speed than the exit conveyor 2202 to ensure that the containers are not abutting one another as they pass through the field of view 2210 (shown in FIG. 22A) of the first sensor 2204 (shown in FIG. 22A).

Returning to FIG. 22A, in at least one example embodiment, the inspection station 2200 is configured to eject containers that do not pass inspection (e.g., product is not fully enclosed by the container, as determined by a signal from the first sensor 2204. The inspection system 2200 may include an air nozzle 2230 downstream of the first sensor 2204. The air nozzle 2230 may be configured to direct one or more streams of air toward a container to direct the container into a reject chute 2232. The reject chute 2232 may be configured to guide rejected containers into a reject bin 2234.

In at least one example embodiment, the inspection station 2200 may include a third sensor 2236 adjacent to the reject chute 2232. The third sensor 2236 may be configured to indicate whether a container has been transferred from the exit conveyor 2202 to the reject chute 2232. The third sensor 2236 may be a light sensor, such as a fiber-optic sensor, a laser sensor, a photoelectric sensor, a color sensor, another type of light sensor, a non-light sensor, or any combination thereof.

FIG. 23 is a flowchart depicting a method of filling containers with products according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 23, a method of loading a container with a product includes providing a product at 52300. At S2304, the method may include metering the product and transferring the product to a shuttle. At S2308, the method may further include providing containers to a container loading station. At S2312, the method may further include transferring the products to the container loading station. At 53216, the method may further include loading the products into the containers. At S3220, the method may further include inspecting the containers.

Providing products at 52300 may, in at least one example embodiment, include forming the products. The products may be formed at the product forming station 102 of FIGS. 1A-1B. In at least one example embodiment, forming the products includes forming oral pouch products.

Metering the product and transferring the shuttle at S2304 may be performed at the product metering station 104 of FIGS. 1A-1B.

FIGS. 24A-24E are partial cross-section views depicting the metering the product and transferring the product to a shuttle according to the method of FIG. 23 according to at least one example embodiment.

In at least one example embodiment, as shown in FIGS. 24A-24E, S2304 may be performed at one or more of the lanes 300 of the product metering station 104 (shown in FIGS. 1A-1B). S2304 may be performed while the shuttle assembly 106 is in the first shuttle position 106A (shown in FIG. 1A), the second shuttle position 106B (shown in FIG. 1A), between the first and second shuttle positions 106A, 106B, or any combination thereof, as shown. Accordingly, in at least one example embodiment, products 2400 are continuously provided to each of the lanes 300 regardless of a position of the shuttle assembly 106.

In at least one example embodiment, as shown in FIG. 24A, the shuttle assembly 106 may be away from the first shuttle position 106A, such as in the second shuttle position or an intermediate shuttle position between the first and second shuttle positions. While the shuttle assembly 106 is away from the first shuttle position, S2304 may include transferring a plurality of products 2400 from one of the diverter chutes 302 to one of the respective upper filling tubes 306. The products 2400 may be received by the diverter chute 302, transferred through the upper aperture 414 of the upper filling plate 412, and into the upper filling tube 306, such as by gravity. The filling gate 506 may be in the first filling gate position such that the filling gate 506 retains the products within a middle aperture 2402 of the middle filling plate 310 and/or in the upper filling tube 306.

In at least one example embodiment, the control system 118 may be configured to determine whether products have been transferred into the upper filling tubes 306. The control system 118 may be configured to process the data signal from first sensor 410 (shown in FIG. 4) to determine whether products have been transferred from diverter chute 302 to upper filling tube 306. If product has not been transferred, the control system 118 may be configured to adjust operation of the apparatus 100 (shown in FIGS. 1A-1B) to ensure that a desired or predetermined number of products 2400 reach the portion of the machine (e.g., by performing additional rotations of metering device 320 of FIG. 3).

The shuttle assembly 106 may be translated in a first shuttle direction 2404 (e.g., a horizontal direction) from the second shuttle position to the first shuttle position while products 2400 are being retained by the filling gate 506.

In at least one example embodiment, as shown in FIG. 24B, the shuttle assembly 106 may be in the first shuttle position. In the first shuttle position, the product aperture 606 of the shuttle assembly 106 may be substantially aligned with the diverter chute 302, the upper filling tube 306, and the lower filling tube 308, such as along a longitudinal axis 2406 of the lane 300. When the shuttle assembly 106 is in the first shuttle position, S2304 may include moving the filling gate 506 from the first filling gate position to the second filling gate position to permit the products 2400 to transfer through the middle aperture 2402.

As shown in FIG. 24C, 52404 may include transferring the products 2400 through the lower filling tube 308 and a lower aperture 2408 of the lower filling plate 312 and into the product aperture 606 of the shuttle assembly 106, such as by gravity. The products 2400 may be retained at least partially within the product aperture 606 by the shuttle gate 702 in the first shuttle gate position.

As shown in FIG. 24D, the diverter chute 302 may continue to receive products 2400. The products 2400 may be transferred from the diverter chute 302 to the upper filling tube 306 and directly through the middle aperture 2402, the lower filling tube 308, and the lower aperture 2408 without being stopped by the filling gate 506. The shuttle assembly 106 may continue to receive products 2400 in the above manner until a desired (or alternatively, predetermined) number of products 2400 have been received in each of the product apertures 606 of the shuttle assembly 106.

In at least one example embodiment, as shown in FIG. 24E, S2304 may include translating the shuttle assembly 106 in a second shuttle direction 2410 (e.g., a horizontal direction) opposite the first shuttle direction 2404 from the first shuttle position to the second shuttle position. In at least one example embodiment, the first and second shuttle directions 2404, 2410 are substantially horizontal. S2304 may further include moving the filling gate 506 from the second filling gate position to the first filling gate position.

Returning to FIG. 23, in at least one example embodiment, providing containers to a container loading station may be performed by the container station 108 (shown in FIGS. 1A-1B). In at least one example embodiment, S2308 may include delivering one of the containers 200 (shown in FIGS. 2A-2E) to the nest 902 (shown in FIG. 9) via the receiving opening 917.

FIGS. 25A-25H are schematic views depicting a method of partially opening the container of FIGS. 2A-2E using the pre-opening assembly of FIG. 9 according to at least one example embodiment. FIGS. 2A, 2C, and 2E are front cross-sectional views. FIGS. 2B. 2D, and 2F are side cross-sectional views.

As shown in FIGS. 25A-25B, the container 200 may be oriented such that its third side wall 208C is in the fourth opener direction 930 (e.g., downward) with respect to the first side wall 208A and the lid 204 is in the first opener direction 914 (e.g., forward) with respect to the container base 202. The container 200 may be in the closed configuration.

In at least one example embodiment, S2308 includes determining whether the container 200 is present in the nest 902. In at least one example embodiment, the control system 118 (shown in FIG. 1A) may be configured to determine whether the container 200 is present in the nest 902. The control system 118 may be configured to process a data signal 2500 from the second sensor 918 (shown, with the reflector 920, transposed onto nest 902) to determine whether the container 200 is present in the nest 902.

In at least one example embodiment, the control system 118 may be configured to adjust operation of the apparatus 100 (shown in FIGS. 1A-1B) if the container 200 is not present in the nest 902, such as providing another container 200 via the receiving chute 804 (shown in FIG. 8). If the container 200 is present in the nest 902, it may be retained by a vacuum applied at the vacuum aperture 923.

In at least one example embodiment, as shown in FIGS. 25C-25D, S2308 may include deforming the container 200. Deforming the container 200 may include moving the pinchers 904 from the retracted position (shown in FIG. 9A) to the pinch position, as shown. In a deformed position 2510, the second and fourth side walls 208B, 208D of the container 200 may be bowed into a concave shape and the third side wall 208C may be bowed into a convex shape. The lid 204 may substantially retain its shape while the container base 202 is deformed. Accordingly, the third side wall 208C may become disengaged from the latch 218 of the lid 204.

In at least one example embodiment, S2308 includes partially opening the container 200 (i.e., moving the container from the closed position to the partially opened position). The container 200 may, in at least one example embodiment, be partially opened while it is in the deformed position 2510 (i.e., while the pinchers 904 engage the container body 202). Partially opening the container 200 may include moving the blade 924 from the second blade position (shown in FIGS. 25A-25B) to the first blade position, as shown. In the first blade position, the blade 924 may be at least partially disposed in the first scallop 210 of the container base 202. The blade 924 may engage the lid 204 to facilitate transition of the container 200 from the closed position to the partially open position.

In at least one example embodiment, S2308 may include determining whether the container 200 is in the partially open position. The control system 118 may be configured to determine whether the container 200 is in the partially open position. The control system 118 may be configured to process the data signal from the third sensor 932 (shown transposed onto the nest 902) to determine whether the container 200 is in the partially open position (e.g., based on whether the lid 204 interrupts a space between the transmitter and receiver of the third sensor 932).

In at least one example embodiment, if the container 200 is not in the partially open position (i.e., the container 200 is in the closed position), the blade 924 may return to the second blade position and then repeat movement from the second blade position to the first blade position. This sub-step may be repeated a desired (or alternatively predetermined) number of times to attempt to partially open the container 200. In at least one example embodiment, the pinchers 904 remain in the pinch position while this sub-step is repeated. In at least one other example embodiment, the pinchers 904 may return to the retracted position and repeat movement to the pinch position prior to repeating movement of the blade 924.

In at least one example embodiment, as shown in FIGS. 25E-25F, the blade 924 may be moved in the fourth opener direction 930 (e.g., downward) from the first blade position to the second blade to disengage the container 200.

In at least one example embodiment, S2308 may include moving the nest 902 in the first opener direction 914 (e.g., forward) from the first nest position, as shown, to the second nest position. The container 200 and pinchers 904 may be configured to move together with the nest 902. In at least one example embodiment (not shown), the container 200 may remain between the pinchers 904 in the pinch configuration during all or a portion of the movement from the first nest position to second nest position.

In at least one example embodiment, the pinchers 904 may be moved from the pinch position to the retracted position. The container 200 may transition from the deformed position 2510 (shown in FIG. 25C) to the original position as the pinchers 904 move from the pinch position to the retracted position. In at least one example embodiment, when the nest 902 is in the second nest position and the pinchers 904 are in the retracted position, the container 200 may be free to be transferred through the transfer opening 938 (shown in FIG. 9) and the transfer chute 806 (shown in FIG. 9).

In at least one example embodiment, the blade 924 moves from the first blade position to the second blade position, the nest 902 moves from the first nest position, and the pinchers 904 move from the pinch position to the retracted position sequentially, as described. However, in at least one other example embodiment, movement of the blade 924, the nest 902, and the pinchers 904 is performed in a different order, concurrently, or simultaneously.

Returning to FIGS. 12-13, in at least one example embodiment, S2308 may include transferring the container 200 (shown in FIGS. 2A-2E) to the through the garage opening 1214 and into the garage assembly 1200.

Transferring the container 200 to the exit conveyor 2106 may include operating the transfer assembly 2116 to engage the foot 2122 of the transfer assembly 2116 with the container 200 and push the container 200 onto the exit conveyor 2106.

Otherwise, if the container 200 is not in the closed position, S2316 may include transferring the container 200 into the reject bin 2104. Transferring the container 200 into the reject bin 2104 may include moving the conveyor belt 1220 in the conveyance direction 1326 and dropping the container 200 over the reject bin 2104.

S2316 may further include performing a second inspection of the container 200, such as when the container 200 passes the first inspection and/or is on the exit conveyor 2106. Performing the second inspection may include determining whether any product is outside of the container (e.g., caught between the container base 202 and lid 204 and/or present within a desired or predetermined region surrounding the container 200), or any other suitable inspection. The control system 118 may be configured to determine whether any product 2400 is outside of the container 200 by processing a signal from the seventh sensor (see discussion regarding sensor 2204 of FIG. 22A).

The container 200 may pass the second inspection if no product is outside of the container 200, and/or based on any other desired or predetermined criteria. If the container 200 passes the second inspection, the container 200 may be undergo further inspection (e.g., metal detection and/or weight determination) and/or labeled, sealed, and/or packaged with other containers. In at least one example embodiment, the exit conveyor 2106 is configured to transfer the container to another apparatus, such as to a receiving conveyor of another apparatus. Otherwise, if the container 200 fails the second inspection, it may be transferred into the reject bin 2104 or another reject bin, such as by operation of the third air nozzle (see discussion related to air nozzle 2230 of FIG. 22A). The method may end.
