Abstract

A card dispensing system for dispensing cards along a conveying surface which conveys sliced products downstream of a slicer for packaging the sliced products. A hopper contains a stack of cards which are withdrawn from the hopper by a suction force provided via at least one suction cup. The suction cup is moveable vertically to retrieve and remove the card from the hopper. The suction cup is moveable laterally to move the card into a receiving position where a card clamp on a clamp carriage arrives to receive the card. Suction force on the card is released when the card clamp clamps down on the card. The clamp carriage moves the card from the receiving position to the staging position where a nip engages with the card to feed the card through a junction in the conveyor line just as a food product passes over the junction.

First claim

The invention claimed is:

1. A card dispensing system for use with a conveying surface configured to convey sliced products along the conveying surface downstream of a slicing machine to package the sliced products with a card, comprising:
a first conveyor and a second conveyor, the conveyors in longitudinal alignment with each other and, wherein a conveying surface of the first conveyor and a conveying surface of the second conveyor are in substantially vertical alignment with each other, the first and second conveyors together providing the conveying surface, wherein the conveying surface has a width defined by opposite lateral edges, and wherein the first conveyor and the second conveyor have a gap in the longitudinal direction between adjacent ends thereof;
a card assembly station having a hopper configured to contain a plurality of vertically stacked cards supported within the hopper by support fingers which releasably hold the plurality of vertically stacked cards;
the card assembly station having a portion thereof disposed beneath the hopper for withdrawing a first card positioned at a bottom of the plurality of vertically stacked cards from the hopper past the support fingers, and moving the first card into a receiving position, wherein the receiving position is located below the conveying surface and adjacent one of the lateral edges and away from an area defined between the opposite lateral edges of the conveying surface;
a card transportation mechanism configured to receive the first card at the receiving position and laterally transport the first card to a staging position, wherein the staging position is located below the conveying surface and between the lateral edges of the conveying surface;
a lower card guide plate disposed at least partially in the gap between the first conveyor and the second conveyor at an oblique angle relative to the conveying surface, and located below the conveying surface;
a delivery mechanism located at least partially below the conveying surface and adjacent to the first card when the first card is in the staging position, the delivery mechanism configured to feed the first card from the staging position through the gap and guided by a top surface of the lower card guide plate so that as the sliced product passes over the gap the sliced produce is deposited on the card; and
wherein the card moves from below the conveying surface to a position on top of the conveying surface as the card is transported through the gap.

2. The card dispensing system of claim 1 , wherein the mechanism for withdrawing the first card from the hopper utilizes at least one suction cup to withdraw the first card.

3. The card dispensing system of claim 2 , wherein the at least one suction cup is moveable upwards to retrieve the first card in the hopper, and moveable downwards to move the first card away from cards remaining in the hopper.

4. The card dispensing system of claim 1 , wherein movement of the first card into the receiving position includes a lateral movement.

5. The card dispensing system of claim 1 , wherein the delivery mechanism comprises a nip for receiving the first card at the staging position.

6. The card dispensing system of claim 1 , further comprising a guiding strip disposed beneath the gap, wherein movement of the first card from the receiving position towards the staging position increasingly engages the first card with the guiding strip.

7. A card dispensing system for use with a food product conveying surface, the card dispensing system comprising:
a plurality of longitudinally aligned conveyors spaced apart from one another by a distance defining at least a first gap and a second gap, the first and second gaps disposed between adjacent conveyors of the plurality of conveyors in the longitudinal direction, and wherein conveying surfaces of the plurality of conveyors are in substantial vertical alignment with each other;
a first hopper for containing a first plurality of cards;
a second hopper for containing a second plurality of cards;
a first mechanism for withdrawing a first card from the first hopper and moving the first card into a first receiving position;
a first card transportation mechanism for receiving the first card at the first receiving position and transferring the first card to a first staging position;
a first lower card guide plate disposed at least partially in the first gap at an oblique angle relative to the conveying surface;
a first delivery mechanism for feeding the first card from the first staging position towards the first gap in the conveying surface, wherein the first card is transported through the first gap and guided by a top surface of the first lower card guide;
a second mechanism for withdrawing a second card from the second hopper and moving the second card into a second receiving position;
a second card transportation mechanism for receiving the second card at the second receiving position and transferring the second card to a second staging position;
a second lower card guide plate disposed at least partially in the second gap at an oblique angle relative to the conveying surface; and
a second delivery mechanism for feeding the second card from the second staging position towards the second gap in the conveying surface, wherein the second card is transported through the second gap and guided by a top surface of the second lower card guide.

8. The card dispensing system of claim 7 , wherein the first hopper supports the first plurality of cards in a stacked vertical manner, and wherein the second hopper supports the second plurality of cards in a stacked vertical manner.

9. The card dispensing system of claim 7 , wherein the first and second hoppers are positioned to a side of and out from underneath the conveying surface.

10. The card dispensing system of claim 7 , wherein the first plurality of cards are associated with a first grade of food product and the second plurality of cards are associated with a second grade of food product different than the first grade.

11. The card dispensing system of claim 10 , further comprising a camera configured to capture an image of food product to determine if the food product has the first grade or the second grade.

12. The card dispensing system of claim 11 , wherein the card dispensing system selectively dispenses one of the first or second cards depending on the grade of the food product.

13. A method of dispensing a card upon which a food product is placed in a food processing conveyor line, the method comprising:
capturing an image of a food product;
assigning a first grade or a second grade to the food product based on the image;
withdrawing a first card from a first hopper if the food product is assigned a first grade, and withdrawing a second card from a second hopper if the food product is assigned a second grade;
transporting the first card on a first card transportation mechanism or transporting the second card on a second card transportation mechanism, to a location along the food processing conveyor line where the food product is configured to be disposed on the one of the first card or the second card; and
wherein the food processing conveyor line includes a first conveyor and a second conveyor, the conveyors in longitudinal alignment with each other and having conveying surfaces in substantially vertical alignment with each other, and having a gap defined in the longitudinal direction between adjacent ends of the first and second conveyors, respectively; and
a lower guide plate disposed at least partially in the gap between the first conveyor and the second conveyor at an oblique angle relative to the convey
