With additional reference to
An upper cam plate 119 (
A pair of looped chains 127 or other rotational members can extend in a generally elliptical or otherwise closed path about a plurality of sprockets 129 or other rotationally driven or rotational driving mechanisms that are rotatably mounted to a respective support 117 of the product engagement assembly 103.
A plurality of flight support bars 131 can extend from one chain 127 to the other, above the upper cam plate 119, below the lower cam plate 121, and away from the return rails 123, 125 so as to follow the path formed by the chains 127 in generally elliptical orbit about interiorly-located components of the product engagement assembly 103.
Respective adjacent pairs of flight support bars 131 can support a respective plurality of flight assemblies 133 for engaging respective products in the system 100, as described further herein.
The lower cam plate 121, as shown, can have a body 135 along which a plurality of cam tracks 137 extend that define and/or associated with a plurality of product lanes L1, L2, L3, L4 below which products supported on the conveyor assembly 109 can move, as described further herein.
The cam tracks 137, as shown, can have one or more of straight, curved, and/or angled portions such that at least the product lanes L2, L3, and L4 can extend at least partially in the transverse direction T2 in addition to the machine direction M1. In this regard, the lane L1 can be a generally straight product lane extending in the machine direction L1 and the lanes L2, L3, L4 can be at least partially curved lanes that at least partially diverge from the product lane L1.
The plurality of cam tracks 137 generally converge to a point of intersection with the return rail 123 proximate an upstream end 105 of the system 100, and the plurality of cam tracks 137 can diverge to a point of intersection with the respective return rails 125 proximate a downstream end 107 of the system 100.
In some embodiments, the cam tracks 137 can be at least partially recessed portions of the body 135 of the lower cam plate 121. In other embodiments, the cam tracks 137 can be formed by raised members coupled to the body 135 of the lower cam plate 121.
The body 135 of the lower cam plate 121 can have one or more discontinuities therealong for at least partially receiving other portions of the product engagement assembly 103. In the illustrated embodiment, the body 135 of the lower cam plate 121 can have a plurality of discontinuities for at least partially receiving respective portions of a respective diverter assembly 139 (

With reference to
As described herein, the mount 147 of the diverter assembly 139 can be coupled to a surface of the body 135 of the lower cam plate 121 above the cam tracks 137, and an actuator 155, e.g., a motor such as a servo motor, other actuator, etc., can drive the diverter plate 149 to pivot relative to the mount 147 via a linkage 157 coupled between the actuator 155 and the diverter plate 149. In this regard, the actuator 155 can be energized to selectively at least partially pivotably lower the diverter plate 149 and diverter body 151 carried thereon into at least partially coplanar alignment with the body 135 of the lower cam plate 121 such that the diverter track portions 153 can be positioned along respective portions of respective cam tracks 137.
As shown in
Turning to
The top plate 163 of the flight assembly 163 can at least partially define an elongate slot 173 at least partially defined therethrough that generally aligns with a complementary slot 175 at least partially defined in a frame element 177 positioned below the top plate 163. The aligned slots 173, 175 are arranged for at least partially receiving the lower portion of a cam follower 179 (broadly, “first cam follower” or “second cam follower” or “outer cam follower”) supported on a brace 181.
The aligned slots 173, 175 are further arranged to receive an adapter plate 183 therethrough for effecting rotation of a portion of the flight assembly 133, as described further herein. The adapter plate 183, as shown, is configured for coupling to the lower portion of the cam follower 179 and a portion of the brace 181 extending away therefrom. A rack 185 supports the adapter plate 183 extending upwardly therefrom, and has a body 187 defining a plurality of teeth 189 facing a central portion of the flight assembly 133 to facilitate rotation of a portion thereof, as described further herein.
The top plate 163 also defines an opening 191 for at least partially receiving a cam follower 193 (broadly, “first cam follower” or “second cam follower” “central cam follower”) therethrough, the cam follower 193 generally supported on and extending upwardly from a generally cylindrical base 195.
The base 195, as shown, can be at least partially received in a recessed portion 197 defined in the body 199 of a pinion 201 positioned abutting the rack 185. Accordingly, the body 199 of the pinion 201 includes a gear portion 203 within which the recessed portion 197 is at least partially defined and about which a plurality of teeth 205 are defined in meshing engagement with the teeth 189 of the rack 185 adjacent thereto. The body 199 of the pinion 201 further includes a flange portion 207 extending downwardly from the gear portion 203 thereof.
A generally disc-like plate 209 can be coupled below the flange portion 207 of the pinion 201, and can at least partially receive an attachment bar 211 along a lower portion thereof, the attachment bar 211 for spanning and coupling two a pair of blocks 213 spaced apart from one another.
Each block 213, as shown, includes a body 215 that defines a respective pair of passages therethrough, the respective passage closest the pinion 201 at least partially receiving a respective adjustment bar 217 linearly slidable therethrough. The respective adjustment bar 217 has a respective body 219 defining a plurality of teeth 221 facing an opening 223 in the body 215 of the respective block 213 such that the respective teeth 221 are positioned in meshing engagement with the teeth 225 defined along the body of a lower adjustment gear 227 positioned between the blocks 213. The lower adjustment gear 227 can have upper teeth or another interfacing structure that can mesh with a complementary feature or surface of an upper adjustment gear 226.
In this regard, rotation of the adjustment gears 226, 227 can cause the respective adjustment bar 217 to slid interiorly into the body 215 of the respective block 213 or exteriorly thereof via meshing engagement of the respective teeth 221, 225.
The body 215 of each block 213 can also include a respective passage that at least partially receives a respective bushing tube 229 through which a respective attachment bar 231 is slidably moveable toward and away from the respective block 213.
The respective adjustments bars 217 and respective attachment bars 231 are attached to a pair of product engaging plates 233, as shown, which are spaced apart so as to at least partially receive and engage a product therebetween. The spacing of the product engaging plates 233 is thus determined by the relative extension of the respective adjustment bars 217 and respective attachment bars 231 from the respective blocks 213, such spacing can thus be adjusted via rotation of the adjustment gear 227 to cause the respective adjustment bars 217 to increase or decrease spacing between the product engaging plates 233.
The aforementioned arrangement of the respective flight assemblies 133 is such that the respective flight assemblies 133 are supported on respective flight support bars 131 extending through the respective flanges 165 and block 167.
The cam follower 179 can be forced, e.g., via engagement along a respective cam track 137 in the lower cam plate 121, to slidably move the adapter plate 183 along the aligned slots 173, 175 such that the rack 185 supported therebelow, via engagement of the teeth 189 thereof with the teeth 205 of the abutting pinion 201, causes the pinion 201 to rotate, with the plate 209 coupled therebelow rotating in kind to at least partially turn the blocks 213 and product engagement plates 233 attached thereto via the respective bars 217, 231 relative to the top plate 163. In this regard, the product engagement plates 233 are rotatably coupled to the top plate 163 through the pinion 201 for causing rotation of the product engagement plates 233 relative top the top plate 163.
In this regard, via relative movement of the cam followers 179, 193 of the respective flight assembly 133 along the cam tracks 137 of the lower cam plate 121 of the product engagement assembly, a product captured between the product engagement plates 233 can be caused to rotate for further processing downstream in the system 100.
With reference to
One or more products P can be positioned on the conveyor belt 112 of the conveyor assembly 109 proximate the upstream end 105 of the system 100. In some embodiments, the products P can be received from a portion or station of the system 100 located upstream from the conveyor assembly 109. The products P can be provided in a generally linear fashion, e.g., coaxially disposed along an axis parallel to the machine direction M1, though it will be understood that, in some embodiments, a grouping station or apparatus can effect such arrangement.
One or more driving mechanisms associated with the conveyor assembly 109 can be driven to rotate to move the products P in the machine direction M1. Simultaneously or thereafter, the sprockets 129 of the product engagement assembly 103 can be driven to rotate to move the chains 127 extending therearound in the generally elliptical path, the bottom portion of such path generally extending in the machine direction M1. In this regard, the flight assemblies 133 can be carried on the flight support bars 131 into an overhead arrangement with the products P therebelow on the conveyor belt 112.
The product engagement plates 233 of the respective flight assemblies 133, as described above, can be spaced apart a width sufficient to receive an upper portion of a respective product P therebetween. In some embodiments, the product engagement plates 233 can be provided in an at least partial clamping engagement with a respective product P. As described above, the spacing of the product engagement plates 233 can be adjusted via rotation of the adjustment gear 227 to cause the respective adjustment bars 217 to increase or decrease spacing between the product engaging plates 233.
Upon approaching the respective cam tracks 137, the respective cam followers 179, 193 can enter the respective cam tracks 137 to slidably or rollably move along the sides thereof, driven by the respective flight support bars 131.
The diverter assemblies 139 of the product engagement assembly 103 can generally be disposed in a raised state, e.g., such that the diverter plate 149 and diverter track portions 153 carried thereon are pivoted upwardly and away from alignment with the respective cam tracks 137.
When it is desired to lower a respective diverter track portion 153 into alignment with a cam plate 121/respective cam track 137, the respective actuator 155 can be energized to selectively at least partially pivotably lower the diverter plate 149 and diverter body 151 carried thereon into at least partially coplanar alignment with the body 135 of the lower cam plate 121 such that the diverter track portions 153 can be positioned along respective portions of respective cam tracks 137 so as to divert the respective flight assembly 133 and product P carried thereby into a respective lane L2, L3, L4.
If, however, none of the diverter assemblies 139 are actuated such that the diverter track portions 153 remain raised at least partially away from the lower cam plate 121, the respective flight assembly 133 and product P carried thereby can remain engaged with the cam tracks 137 associated with the lane L1, e.g., so as to move generally linearly in the machine direction M1 without any relative movement of the cam followers 179, 193 to cause rotation of the product engagement plates 233 and product P at least partially held therebetween. In some embodiments, such movement of the flight assembly 133/product P along the lane L1 can be considered a rejection of the respective product P, for example, due to an imperfection, misalignment, to isolate the respective product P for inspection/quality control purposes, etc.
As shown, as the respective flight assemblies 133 move through the respective lanes L2, L3, L4, they approach the respective bypass assemblies 141. Referring again to
As shown, the positioning of a respective cam track portion 161 along a respective cam track 137 is such that cam tracks 137 associated with the cam followers 179, 191 of a respective flight assembly 133 generally converge. In this regard, the respective cam follower 179 is caused to slidably move the adapter plate 183 along the aligned slots 173, 175, e.g., toward the cam follower 191, such that the rack 185 supported therebelow, via engagement of the teeth 189 thereof with the teeth 205 of the abutting pinion 201, causes the pinion 201 to rotate, with the plate 209 coupled therebelow rotating in kind to at least partially turn the blocks 213 and product engagement plates 233 attached thereto via the respective bars 217, 231 relative to the top plate 163.
The effect of the aforementioned rotation of the product engagement plates 233 is such to rotate the respective product P, for example, generally 90 degrees about an axis parallel to the vertical directions V1, V2, though it will be understood that the flight assemblies 133 can be configured to rotate a respective product P to a different degree.
If, however, the respective bypass assemblies 141 are not activated such that the respective cam track portion 161 remains in an at least partially raised state out of alignment with the respective cam track 137, the cam follower 179 remains generally unforced and unmoved relative to the cam follower 193, such that no rotation of the pinion 201 and product engagement plates 233 at least partially holding the product P is effected such that a rotational arrangement of the respective flight assembly 133 is maintained. Accordingly, the product P can arrive at a downstream portion of a respective lane L2, L3, L4 in a generally similar rotational configuration as that upon entry on the conveyor belt 112, which may be desirable in some situations, e.g., during maintenance and/or switchover operations, etc.
Upon arriving at the downstream end 107 of the system 100, at least the respective cam follower 193 of the respective flight assembly 133 can enter a respective return rail 125 and a respective return cam track 147 for travel in the machine direction M2 toward and onto the return rail 123, which returns the respective flight assembly 133 to the upstream end 105 of the system 100, partially shown in
In some embodiments, the arrangement of cam tracks 147 along the upper cam plate 119 can be such to cause the cam follower 179 is caused to slidably move the adapter plate 183 along the aligned slots 173, 175, e.g., away from the cam follower 193, such that the rack 185 supported therebelow, via engagement of the teeth 189 thereof with the teeth 205 of the abutting pinion 201, causes the pinion 201 to rotate, with the plate 209 coupled therebelow rotating in kind to at least partially turn the blocks 213 and product engagement plates 233 attached thereto via the respective bars 217, 231 relative to the top plate 163, having the effect of generally reversing the rotational orientation of the product engagement plates 233 effected by engagement with the lower cam plate 121 as described above.
In view of the foregoing, a system 100 with a product engagement assembly 103 is provided for efficiently providing selective rotational arrangements of products carried thereon, which can optimize loading and transferring operations, for example, and which is reconfigurable toward a large variety of different applications.
It will be understood that one or more components of the system 100 can have a different configuration, position, arrangement, etc., without departing from the disclosure.
