Automatic grouping system for food products
View Patent ↗An automated grouping system of bakery products increases a quantity of bakery products that may be fed to equipment having a larger processing capacity. The automated grouping system includes a supporting structure laterally arranged adjacent to a conveyor of bakery products. The structure includes two longitudinally-arranged lateral rails. Sliding supports, along with first linear driving actuators of regulated stroke, are mounted on the lateral rails. Each sliding support includes a vertical post and a cross guide fixed at an upper portion thereof. The structure also includes a pair of second linear vertical actuators, which support and actuate a pair of pulling plates and positioning mechanisms of bakery products. The pulling plates are also actuatable by third linear actuators of regulated stroke, which are provided on a lower cross member, to position the pulling plates in a direction transverse to a conveying direction of the bakery products.
1. An automated system for grouping bakery products comprising:
a conveyor;
a supporting structure adjacent to the conveyor, the support structure comprising:
a first lateral rail disposed parallel to a first side of the conveyor;
a second lateral rail disposed parallel to a second side of the conveyor opposite the first side;
a sliding support disposed on each of the first and second lateral rails;
first linear actuators operable to longitudinally displace the sliding supports in both a conveying direction and in a direction opposite the conveying direction;
a vertical post attached to each sliding support;
a cross guide extending between the vertical posts on an upper portion of said posts;
a pair of second actuators disposed on the cross guide;
a pulling plate attached to each second actuator, wherein the second actuators are operable to vertically position the pulling plates relative to the conveyor;
a positioning mechanism secured to each pulling plate and operable to reposition one or more bakery products on the conveyor;
a lower cross member extending between the vertical posts on a lower portion of said posts; and
third linear actuators disposed on the lower cross member and operable to displace the pulling plates in a direction transverse to the conveying direction.
2. The automated system according to claim 1 , wherein the system is operable to transversely align one or more bakery products from a second row of bakery products with a first row of bakery products.
3. The automated system according to claim 1 , wherein the positioning mechanisms each comprise one or more compartments, wherein each compartment is adapted to receive an individual bakery product.
4. The automated system according to claim 3 , wherein each compartment is defined by substantially parallel adjacent vertical plates and a vertical backing plate disposed proximate to a trailing end of the adjacent vertical plates.
5. The automated system according to claim 1 further comprising a sensor to sense the position of a row of bakery products on the conveyor.
6. A method of grouping bakery products on a conveyor comprising: detecting a first row of bakery products moving along the conveyor in a conveying direction;
dividing a second row of bakery products;
aligning a first portion of the bakery products of the second row at a first end of the first row of bakery products; and
aligning a second portion of the bakery products of the second row at a second end of the first row of bakery products,
wherein the dividing of the second row of bakery products comprises lowering a first positioning mechanism over the first portion of bakery products in the second row; and lowering a second positioning mechanism over the second portion of bakery products in the second row.
7. A method of grouping bakery products on a conveyor comprising: detecting a first row of bakery products moving along the conveyor in a conveying direction;
dividing a second row of bakery products;
aligning a first portion of the bakery products of the second row at a first end of the first row of bakery products; and
aligning a second portion of the bakery products of the second row at a second end of the first row of bakery products,
wherein the aligning of the first and second portions of bakery products comprises:
moving the first portion of bakery products towards a first edge of the conveyor;
moving the first portion of bakery products in the conveying direction until the first portion of bakery products aligns laterally with the first row of bakery products;
moving the second portion of bakery products towards a second edge of the conveyor; and
moving the second portion of bakery products in the conveying direction until the first portion of bakery products aligns with the first row of bakery products.
8. The method according to claim 7 , wherein moving the first portion of bakery products towards the first edge of the conveyor occurs until an innermost bakery product of the first portion is laterally offset from an outermost bakery product at the first end of the first row of bakery products, and wherein moving the second portion of bakery products towards the second edge of the conveyor occurs until an innermost bakery product of the second portion is laterally offset from an outermost bakery product at the second end of the first row of bakery products.
9. A method for grouping bakery products utilizing an automated grouping system having a conveyor and first and second positioning mechanisms, the method comprising:
sensing a first row of bakery products;
laterally displacing the first and second positioning mechanisms to a center portion of the conveyor;
passing the first row of bakery products past the first and second positioning mechanisms;
lowering the first and second positioning mechanisms onto a second row of bakery products following the first row so that the second row is divided into a first portion of bakery products and a second portion of bakery products;
laterally displacing the first and second positioning mechanisms perpendicular to each other and proximal to opposite edges of the conveyor; and
displacing the first and second positioning mechanisms in a conveying direction of the conveyor until the first portion of the bakery products aligns with the first row at a first end thereof and the second portion of bakery products aligns with the first row at a second end thereof.
10. The method according to claim 9 , wherein the first and second positioning mechanisms move substantially simultaneously.
