DETAILED DESCRIPTION
Arranging items may be accomplished as disclosed herein. Particularly, bakery products such as hot dog buns or other elongated bakery products may be aligned into one or more rows. Moreover, the one or more rows may be oriented parallel to each other. Although bakery products are used throughout the present disclosure, it is understood that other items may be arranged as described herein. Thus, the present disclosure is not limited to elongated bakery products. Rather, elongated bakery products are used merely as examples.
FIGS. 1-4 show an example apparatus 10 for arranging elongated bakery products. The apparatus 10 may be disposed between product transport devices. For example, as shown in FIG. 1, the apparatus 10 may be disposed between a first conveyor 20 and a second conveyor 30. However, other product transport devices operable to transport one or more products may be used. Thus, the apparatus 10 may form a portion of a conveying system for both conveying and aligning a plurality of bakery products 40, particularly elongated bakery products. The plurality of bakery products 40 may be conveyed to the apparatus 10 at a first end 50 thereof by the first conveyor 20. The apparatus 10 may then deposit the aligned or substantially aligned bakery products 40 onto the second conveyor 30 disposed at a second end 60 of the apparatus 10. The bakery products 40 may be deposited onto the second conveyor 30 in one or more aligned rows 65. The second conveyor 30 may convey the bakery products 40 to a subsequent operation for further processing, such as packing of the bakery products 40, for example. Although the apparatus 10 is shown disposed between first and second conveyors 20 and 30, the apparatus 10 may be adjacent only one conveyor. Further still, the apparatus 10 may not be used directly adjacent to any conveyors.
The apparatus 10 may include a support structure 70 and a plurality of rotatable members 80 arranged transverse to a longitudinal axis X-X of the support structure 70. According to some implementations, the support structure 70 may include a pair of side members 90 and a pair of legs 100 extending from each of the side members 90. A brace member 110 may extend between adjacent legs 100 at the first end 50 of the apparatus 10 and between adjacent legs 100 at the second end 60 of the apparatus 10. The support structure 70 may also include a drive support 120 and drive source 130. According to some implementations, the drive source 130 may be an electric motor, a combustion engine, or any other device operable to drive the rotatable members 80. Still further, the drive source 130 of the apparatus 10 may be a gear, belt, shaft, or other mechanical or electrical device operable to provide power to the apparatus 10. The drive source 130 may be disposed on the drive support 120, below the plurality of rotatable members 80.
The rotatable members 80 extend between the side members 90. According to some implementations, the rotatable members 80 are disposed transversely or substantially transversely to the side members 90. However, the rotatable members 80 may be disposed at any angle relative to the side members 90. Further, the rotatable members 80 may rotate in bearings retained in or on the side members 90. Also, each rotatable member 80 may be include one or more sprockets 140. As shown in FIG. 2, some rotatable members 80 include a sprocket 140 at or near a single end thereof, while other rotatable members 80 include a sprocket 140 at or near opposing ends thereof
Referring to the schematic shown in FIG. 5, at least one of the rotatable members 80 includes a drive sprocket 150. The drive sprocket 150 is coupled to a drive sprocket 152 of the drive source 130 via a first drive member 160. According to some implementations, the first drive member 160 may be a continuous belt, chain, or other member operable to drive one or more sprockets. It will be understood that pulleys configured to receive belts may be used instead of sprockets, and the present disclosure is not limited to use of sprockets to drive the rotatable members 80. The disclosure encompasses the use of pulleys and belts and other conventionally known drive systems.
When the drive source 130 is operated, the rotatable member 80 attached to the drive sprocket 150 is rotated. As shown in the example implementation, the rotatable member 80 to which the drive sprocket 150 is attached includes a sprocket 140 at an opposite end that is coupled to a second drive member 170. The second drive member 170 extends between a plurality of sprockets 140. The second drive member 170 transfers a rotation from the rotatable member 80 having the drive sprocket 150 to the other rotatable members 80 having sprockets 140 engaged by the second drive member 170. The second drive member 170 may be, for example, a belt, chain, or other member operable to drive one or more sprockets 140. Consequently, the first and second drive members 160 and 170 are operable to rotate a plurality of the rotatable members 80. Further, the implementations shown in FIGS. 1-5 are merely examples. Therefore, other implementations may include more or fewer rotatable members 80 driven by the second drive member 170.
A third drive member 180 may be provided along a plurality of the rotatable members 80 engaged by the second drive member 120 and may be disposed along ends of the rotatable members 80 opposite the second drive member 120. Although shown as engaging only a portion of the rotatable members 80 engaged by the second drive member 170, the third drive member 180 may engage all of the rotatable members 80 engaged by the second drive member 170. Still further, the third rotatable member 180 may engage other rotatable members 80 in addition to some or all of the rotatable members 80 engaged by the second drive member 170. The third drive member 180 engages a plurality of sprockets 140 attached to the rotatable members 80 and is operable to rotate the engaged rotatable members 80. The apparatus 10 may include additional drive members, such as drive members 190, 200, 210, 230, and 250, to rotate additional rotatable members 80 in a manner similar to that described above. The drive members 190, 200, 210, 220, 230, and 250 may be, for example, a belt, chain, or other member operable to drive one or more sprockets. Further, the drive members 160, 170, 180, 190, 200, 210, 220, 230, and 250 and the drive source 130 form a drive system operable to rotate the rotatable members 80.
As explained above, the apparatus 10 may include drive members 220 and 250, shown in FIG. 5. The drive members 220 and 250 are disposed between a first sprockets 260 and a second sprocket 270 attached to rotatable members 280. As shown, two rotatable members 280 are provided at the first end 50 of the apparatus 10 and a single rotatable member 280 is provided at the second end 60 of the apparatus. The rotatable members 280 at the first end 50 is coupled to the drive member 220, and the rotatable member 281 at the second end 60 is coupled to the drive member 250. More or fewer rotatable members 230 may be provided at the ends 50 and/or 60 of the apparatus 10.
The first sprockets 260 may be larger in diameter than the second sprockets 270. Therefore, the second sprockets 270 may rotate faster (i.e., rotating with a larger number of revolutions per minute (RPM)) than the first sprockets 260. Consequently, the rotatable members 280 may rotate faster than the rotatable members 80 attached to the first sprocket 260. As a result, when a bakery product 40 comes into contact with the rotatable members 230 proximal to the first end 50, an end of the bakery product 40 may be accelerated. The acceleration may impart a rotation to the bakery product 40, for example, to rotate the bakery product 40 within a horizontal plane, thereby placing the bakery product 40 into better alignment with the conveying direction of the apparatus 10. At the second end 60 of the apparatus 10, the increased speed of rotation of the rotatable member 280 may accelerate the bakery products 40 away from the apparatus 10 and onto the second conveyor 30 as the bakery products 40 exit the apparatus 10.
The apparatus 10 shown in FIGS. 1-5 represents merely one possible implementation. Accordingly, other implementations are encompassed within the scope of the present disclosure. For example, other implementations may include additional or fewer rotatable members, sprockets, drive members, and/or drive sources arranged in the same or different configurations in order to convey one or more bakery products. Accordingly, it is intended that the present disclosure encompass all such implementations.
Referring to FIGS. 2 and 6, each of the rotatable members 80 includes a plurality of radially enlarged portions 290 having sloped side walls 300 and a width 310. A channel portion 320 having a width 330 is formed between adjacent radially enlarged portions 290. The radially enlarged portions 320 of adjacent rotatable members 80 may be aligned or substantially aligned so that the channel portions 320 and sloped sidewalls 300 of adjacent rotatable members 80 form channels 340 extending between the first and second ends 50 and 60 of the apparatus 10. The channels 340 form pathways for conveying the bakery products 40. Although FIGS. 1-5 show the apparatus 10 in which the radially enlarged portions are directly aligned, according to other implementations, the radially enlarged portions may be offset from each other to form channels that are skewed from a direction perpendicular to a rotatable members. That is, the channels may not be parallel with a direction normal to the axis of rotation of the rotatable members.
The rotatable members 80 may be arranged, for example, so that the width 310 of the radially enlarged portions 290 may become progressively larger between the first and second ends 50 and 60 of the apparatus 10. Thus, the channels 340 may become increasingly narrow as the width 330 of the channel portions 320 decreases from the first end 50 to the second end 60. For example, as shown in FIG. 2, the rotatable members 80 may be arranged in one or more groups with the width 310 of the radially enlarged portions 290 varying between groups but constant within each group. As a result, each group of rotatable members 80 may include radially enlarged portions 290 that have a constant width 310 within each group but different between groups. As shown in FIG. 2, the rotatable members 80 are arranged in three separate groups 350-370. However, the apparatus 10 may include additional or fewer groups of the rotatable members 80. The radially enlarged portions 290 of the first group 350 may have the smallest width; the radially enlarged portions 290 of the second group 360 with the second largest width; and the radially enlarged portions 290 of the third group 370 may have the largest width. Alternately, each rotatable member 80 may have radially enlarged portions 290 with different widths 290 that increase progressively from the first end 50 to the second end 60 of the apparatus 10.
In operation, the plurality of bakery products 40 disposed on the first conveyor 20 approach the apparatus 10. The first conveyor 20 may convey the bakery products 40 from a previous processing station, such as a baking operation. Further, the bakery products 40 may have skewed or random orientations such that the bakery products 40 are not longitudinally aligned with the conveying direction. The bakery products 40 first engage the rotatable members 280, which may impart a torque to an end of a skewed elongated bakery product 40 to aid in aligning the bakery product 40 with the conveying direction, as explained above. However, one or more of the bakery products 40 may still have a skewed orientation relative to the conveying direction. As the bakery products 40 proceed, the bakery product 40 may contact a radially enlarged portion 290 of one of the rotatable members 80 provided at or near the first end 50 of the apparatus 10. If the bakery product 40 has an orientation skewed relative to the conveying direction, a first end of the bakery product may contact a sloped sidewall 300 of one of the radially enlarged portions 290. The sloped sidewall 300 may further act to align the bakery products 40 with the conveying direction. Thus, contact with the sloped wall 300 may cause the skewed bakery products 40 to become further aligned while also defining a particular channel 340 along which the bakery products 40 are conveyed. As the bakery products 40 continue along the length of the apparatus, the channels 340 narrow, which further directs the bakery product into a desired alignment.
At the second end 60 of the apparatus 10, the bakery products 40 may be removed onto the second conveyor 30, such as by an acceleration from the rotatable member 280. The bakery products 40 are removed onto the second conveyor 30 in a plurality of aligned or substantially aligned rows 65, illustrated in FIG. 1. The aligned bakery products 40 may then be conveyed to a next operation, such as packaging.
The various implementations described herein provide various benefits including, for example, providing uniform distribution of products, preventing or substantially reducing damage to the products while being conveyed and/or aligned, and maintaining an alignment of the products while being conveyed. Implementations may also be used to arrange products having a particular shapes. Additional benefits include continuously and smoothly aligning products (e.g., fragile products susceptible to damage), facilitating packaging as well as other processing operations (e.g., slicing) of the products, reducing and/or eliminating handling of the products by humans, and reducing manpower and/or costs associated with aligning the products.
A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the present disclosure. Accordingly, other implementations are within the scope of the following claims.
