[0041] Some detailed example embodiments are disclosed herein. However, specific structural and functional details disclosed herein are merely representative for purposes of describing example embodiments. Example embodiments may, however, be embodied in many alternate forms and should not be construed as limited to only the example embodiments set forth herein.

[0042] Accordingly, while example embodiments are capable of various modifications and alternative forms, example embodiments 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 embodiments to the particular forms disclosed, but to the contrary, example embodiments are to cover all modifications, equivalents, and alternatives falling within the scope of example embodiments. Like numbers refer to like elements throughout the description of the figures.

[0043] 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.

[0044] 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, component, region, layer, or section discussed below could be termed a second element, region, layer, or section without departing from the teachings of example embodiments.

[0045] 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.

[0046] The terminology used herein is for the purpose of describing various example embodiments only and is not intended to be limiting of example embodiments. 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.

[0047] Example embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of example embodiments. As such, variations from the shapes of the illustrations are to be expected. Thus, example embodiments should not be construed as limited to the shapes of regions illustrated herein but are to include deviations and variations in shapes. When the terms “about” or “substantially” are used 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 the context indicates otherwise.

[0048] 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 embodiments 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.

[0049] As used herein, “coupled” includes both removably coupled and permanently coupled. When the elastic layer and the support layer are removably coupled to one another, the elastic layer and the support layer can be separated upon the application of sufficient force.

[0050] Referring generally to the figures, an in-cartridge above auger agitation is provided. In particular, an agitator is positioned adjacent to an auger to keep filler from bridging and assists in filling the voids present in the auger. For example, agitation is integrated into an existing auger cartridge. A vibratory feeder feeds filler above the agitator / cartridge, keeping a consistent volume and pressure on top of the agitator. The agitator is moved back and forth, and may sweep in varying degrees of rotation, as described further herein. It may also be moved in a constant direction with a ratcheting, or agitator mechanism.

[0085] Referring now to FIG. 12, the link 346 of the agitator assembly 300 (e.g., the link 202) is illustrated. The link 346 is configured to cause rotation of certain components of the agitator assembly 300. The link 346 may include an attachment member 348 and an elongated member 350 extending therefrom. The link 346 is an integral component defined by the attachment member 348 and the elongated member 350. The attachment member 348 includes a rounded portion 352. The rounded portion 352 is configured to correspond with the divot 344 of the snout 328. Accordingly, when a force is applied to the link 346 via the elongated member 350, the attachment member 348 rotates, thus rotating the snout end plate 330 along with it. In at least one example embodiment, the link 346 is configured to rotate 120 degrees. In at least one example embodiment, the link 346 is configured to rotate between a range of 30 degrees and 180 degrees.

[0086] The attachment member 348 of the link 346 further includes a hollow portion 353. The hollow portion 353 may be a cylindrical void within the attachment member 348. Thus, the link 346 is configured to receive the agitator connector 356 via the hollow portion 353. The attachment member 348 further includes a key 354 extending from an inner surface of the hollow portion 353.

[0087] Referring now to FIG. 13, the agitator connector 356 of the agitator assembly 300 is illustrated. The agitator connector 356 includes a proximal end 358 and a distal end 360. The agitator connector 356 includes an agitator end plate 362 and an agitator shaft 364 extending therefrom. For example, the agitator shaft 364 may extend proximally from the agitator end plate 362.

Further, the agitator housing 372 includes a proximal end surface 378 and a distal end surface 380.

[0091] The agitator housing 372 includes an agitator housing channel 381. The agitator housing channel 381 extends from the proximal end surface 378 to the distal end surface 380. The agitator housing channel 381 is configured to receive the agitator shaft 364. For example, when the agitator shaft 364 is inserted into the agitator housing channel 381, the agitator end plate 362 is engaged with the distal end surface 380 of the agitator housing 372. Further, after the agitator shaft 364 is inserted into the agitator housing channel 381, the link 346 may be coupled (e.g., bolted) to the agitator shaft 364 such that the attachment member 348 is in contact with the proximal end surface 378 of the agitator housing 372.

[0092] In at least one example embodiment, the agitator assembly 300 further includes at least one bearing 382 (see also FIG. 19). The at least one bearing 382 may be disposed between the agitator shaft 364 and the agitator housing 372. Accordingly, the at least one bearing 382 further facilitates rotation of the agitator shaft 364 within the agitator housing 372.

[0093] Referring still to FIG. 15, in at least one example embodiment, the agitator housing 372 includes at least one through hole 384. The at least one through hole 384 extends from the flat surface 374 to the rounded surface 376. The at least one through hole 384 is configured to receive a bolt such that the agitator housing 372 is bolted to the auger cartridge 400. In at least one example embodiment, the at least one through hole 384 includes two through holes 384. Each through hole 384 is configured to receive a respective bolt. However, the at least one through hole 384 is not limited to two.

[0094] The agitator housing 372 is configured to be separable from the auger cartridge 400 to facilitate serviceability. For example, if the at least one bearing 382 wears out, the agitator housing 372 may be removed and the at least one bearing 382 may be individually replaced. Similarly, if components such as the agitator connector 356 or the plurality of prongs need to be serviced, the agitator housing 372 may be removed to access such components, creating a modular, serviceable, and rebuildable assembly.

[0095] Referring now to FIGS. 16-17, the auger cartridge is illustrated. In at least one example embodiment, the auger cartridge 400 is generally cylindrical. The auger cartridge 400 includes a proximal end 402 and a distal end 404 opposite the proximal end 402. The auger cartridge 400 includes a proximal end surface 406 at the proximal end 402 and a distal end surface 408 at the distal end 404.

[0096] The auger cartridge 400 includes a distal end cavity 410. The distal end cavity 410 may extend proximally from the distal end surface 408 and through at least a portion of the auger cartridge 400. The auger cartridge 400 includes a step 412 configured to engage with the bearing assembly 320, as will described further herein. The auger cartridge 400 further includes an inner wall 414 configured to substantially enclose the distal end cavity 410, other than an opening 416.

[0097] The auger cartridge 400 includes a proximal end channel 418. The proximal end channel 418 may extend distally from the proximal end surface 406 and through at least a portion of the auger cartridge 400. The proximal end channel 418 and the distal end cavity 410 are concentric. The auger cartridge 400 includes a step 420 configured to engage with the snout 328, as will described further herein.

[0098] The auger cartridge 400 includes a platform 422. The platform 422 extends distally from the proximal end surface 406 and perpendicular to the proximal end surface 406. In other words, the platform 422 may cut out a portion of the otherwise cylindrical shape of the auger cartridge 400. The platform 422 may extend a same length as the proximal end channel 418. For example, the platform 422 may define an upper surface of the proximal end channel 418. The platform 422 may include various holes 424 configured to receive bolts in order to connect the auger cartridge 400 to the agitator assembly 300, as will be described further herein.

[0099] The auger cartridge 400 further includes a central cavity 426. The central cavity 426 may extend between the inner wall 414 and the platform 422. The central cavity 426 may expose an inner surface 428 of the auger cartridge 400. In other words, the central cavity 426 may cut out a portion of the otherwise cylindrical shape of the auger cartridge 400.

[0100] Referring now to FIGS. 18-19, the relationship between the auger cartridge 400 and the agitator assembly is illustrated. The distal end cavity 410 is configured to receive at least a portion of the bearing assembly 320. For example, in at least one example embodiment, the second bearing 324 is received entirely within the distal end cavity 410 and the first bearing 322 extends beyond the distal end surface 408 of the auger cartridge 400. Accordingly, the step 412 configured to correspond with a step formed between the first bearing 322 and the second bearing 324 due to the difference between the first diameter and the second diameter for the first bearing 322 and the second bearing 324, respectively. In at least one example embodiment, the first bearing 322 may be bolted to the distal end surface 408.

[0101] Further, the distal end cavity 410 may enclose the second bearing 324 at the inner wall 414 such that only the auger shaft 316 extends proximally beyond the distal end cavity 410 through opening 416 when the auger 302 is received by the bearing assembly 320 and the auger cartridge 400.

[0102] The proximal end channel 418 is configured to receive at least a portion of the auger 302. Particularly, the auger shaft 316 may extend through the proximal end channel 418 and extend beyond the proximal end surface 406. The proximal end channel 418 and the distal end cavity 410 are concentric such that the auger shaft 316 may extend from the distal end cavity 410 to the proximal end channel 418 and parallel to the longitudinal axis 204.

[0103] When the auger cartridge 400 and the agitator assembly 300 are coupled, the snout end plate 330 may be in confronting relation with the auger cartridge 400. Particularly, the attachment point 338 may be configured to correspond with the step 420 of the proximal end surface 406. Additionally, the snout end plate 330 may be bolted to the proximal end surface 406 of the auger cartridge 400.

[0104] Similarly, when the auger cartridge 400 and the agitator assembly 300 are coupled, the flat surface 374 of the agitator housing 372 may be in confronting relation with the auger cartridge 400, and particularly, with the platform 422 of the auger cartridge 400. The agitator housing 372 may be bolted to the platform 422 via bolts through the at least one through hole 384, thus securing the agitator connector 356 and the link 346 in place (e.g., when the link 346 is coupled to the agitator connector 356). Accordingly, the link 346 is engaged with the snout 328 in such a configuration.

[0105] Further, the plurality of prongs 368 are configured to be received within the central cavity 426. The plurality of prongs 368 are thus exposed. Or not enclosed by the auger cartridge 400. Accordingly, the plurality of prongs 368 may be free of interference and able to rotate, thus facilitating a consistent flow of the filler. For example, the plurality of prongs 368 are aligned with the opening 116 of the housing and thus aligned with the vibratory hopper 104 such that the plurality of prongs 368 are the first point of contact of the auger assembly 200 with the filler when the auger assembly 200 receives the filler from the vibratory hopper 104.

[0106] Referring now generally to the figures, the main link 208 is configured to be coupled to the communal link 206 and a servo motor 210. Accordingly, the servo motor 210 may drive the main link 208, which drives the communal link 206, which drives the plurality of links 202 (e.g., link 346), and thus the plurality of auger assemblies 200. Particularly, the respective link 202 drives the agitator connector 356 and thus the plurality of prongs 368 rotate as the link 202 rotates. While the plurality of prongs 368 ensure a consistent flow of filler into the auger assembly 200, the auger 302 is conveying the filler through the auger assembly 200 to exit as the snout 328.
