Food product conveyor and handling systems
View Patent ↗A conveyor system for assembling and stacking sliced food products is provided. The conveyor system includes an assembly area, wherein groups of a predetermined quantity of sliced food products travel from a slicer on a conveyor and are deposited on discrete carrier sheets on a downstream conveyor. The assembly area is configured to delay advancement of the carrier sheets on the downstream conveyor until a group of the predetermined quantity is formed. The slicer is configured to calculate the number of slices in each group and determine whether a group is complete. A stacking area of the conveyor system includes a nose conveyor that extends and retracts to deposit each carrier sheet onto a pair of initial supports. The initial supports reciprocate away from each other in opposing directions to drop the carrier sheet onto a subsequent level, with the initial supports reciprocating each time a carrier sheet is deposited thereon.
1. An apparatus for assembling sliced food products, the apparatus comprising:
an upstream conveyor that transports a plurality of sliced food products;
a discrete carrier sheet that supports a predetermined number of sliced food products, wherein the upstream conveyor deposits the sliced food products on the discrete carrier sheet that is supported upon a downstream conveyor;
the downstream conveyor that supports and advances the discrete carrier sheet both prior to and after the sliced food products have been deposited on the discrete carrier sheet, wherein the discrete carrier sheet advances along the downstream conveyor, the downstream conveyor having operative and paused modes of operation wherein the downstream conveyor is in the operative mode before entering the paused mode;
a control that calculates whether the discrete carrier sheet contains less than the predetermined number of sliced food products; and
a controller in communication with the control and the downstream conveyor such that the downstream conveyor operates in a paused mode after advancing the discrete carrier sheet along the downstream conveyor when the controller communicates that the discrete carrier sheet contains less than the predetermined number of sliced food products based on control calculations and operates in an operative mode again when the controller communicates that the discrete carrier sheet contains the predetermined number of sliced food products based on control calculations, remaining in the paused mode until the predetermined number of sliced food products have been deposited on the discrete carrier sheet.
2. An apparatus for assembling sliced food products in accordance with claim 1 further comprising a slicer upstream of the upstream conveyor configured to slice a food product mass into the plurality of discrete sliced food products.
3. An apparatus for assembling sliced food products in accordance with claim 2 wherein the control is configured to calculate the number of discrete sliced food products produced by the slicer when slicing the food product mass.
4. An apparatus for assembling sliced food products in accordance with claim 3 wherein the slicer is configured to slice the food product mass into groups of the predetermined number until a group of less than the predetermined number can be formed from a remaining portion of the food product mass.
5. An apparatus for assembling sliced food products in accordance with claim 4 wherein the control is configured to calculate the number of slices comprising the group of less than the predetermined number.
6. An apparatus for assembling sliced food products in accordance with claim 5 wherein the slicer is configured to slice a subsequent food product mass and a first grouping of the sliced food products from the subsequent food product mass will equal a number of sliced food products needed to equal the predetermined number.
7. An apparatus for assembling sliced food products in accordance with claim 6 wherein the upstream conveyor includes a ramp conveyor leading to the downstream conveyor and wherein the ramp conveyor is configured to extend over the discrete carrier sheet in the paused mode to deposit the first grouping of the sliced food products onto the discrete carrier sheet to form a group of the predetermined number of sliced food products.
8. An apparatus for assembling sliced food products in accordance with claim 1 further comprising a bypass conveyor adjacent a portion of the downstream conveyor for rejected food products.
9. An apparatus for assembling sliced food products in accordance with claim 8 further comprising a diverting conveyor configured to transition between a raised position to direct rejected food products from the downstream conveyor to the bypass conveyor and a lowered position to allow non-rejected food products to continue on the downstream conveyor.
10. An apparatus for stacking food products in accordance with claim 9 further comprising a sensor adjacent the downstream conveyor and upstream of the diverting conveyor to detect a predetermined parameter to determine whether a sliced food product is rejected and diverted to the bypass conveyor.
