Abstract

A method and system for packaging products provides for initially, vertically stacking a plurality of products during production in a transfer canister, simultaneously removing a stack of the products from the transfer canister, reorienting the stack and horizontally loading the stack into a final product package cavity. The invention has applicability to a wide range of products, particularly food products, such as refrigerated dough products. In one embodiment of the invention, the product package cavity is thermoformed as part as an overall horizontal form, fill and seal system.

First claim

We claim:

1. A method of simultaneously packaging a plurality of products comprising:
vertically stacking the plurality of products in a movable transfer canister;
opening the movable transfer canister to expose the plurality of products by opening one or more doors of the movable transfer canister;
removing the plurality of products as a stack from the movable transfer canister;
rotating the stack from a substantially vertical orientation to a substantially horizontal orientation;
horizontally loading the stack in a product receiving cavity; and
sealing the stack in the product receiving cavity.

2. The method of claim 1 , further comprising: engaging an activator of the movable transfer canister by a pick-up device in order to open the movable transfer canister.

3. The method of claim 1 , further comprising: removing the stack with a pick-off device which vertically clamps the stack.

4. The method of claim 3 , wherein the pick-off device further clamps sides of the stack.

5. The method of claim 1 , further comprising: forming the product receiving cavity in a thermoforming device of a horizontal form, fill and seal system.

6. The method of claim 1 , further comprising: forming and, immediately thereafter, vertically supplying respective ones of the plurality of products directly into the movable transfer canister.

7. The method of claim 6 , wherein each of the plurality of products is made from dough which is cut from a sheet of dough and individually forcibly vertically loaded in the movable transfer canister.

8. A method of simultaneously packaging a plurality of products comprising:
vertically stacking the plurality of products in a movable transfer canister;
opening the movable transfer canister with an auxiliary mechanism;
removing the plurality of products as a stack from the movable transfer canister with a pick-off device;
rotating the stack from a substantially vertical orientation to a substantially horizontal orientation;
horizontally loading the stack in a product receiving cavity; and
sealing the stack in the product receiving cavity.

9. The method of claim 8 , further comprising: forcibly pivoting a door portion of the movable transfer canister relative to a support body portion of the movable transfer canister with the auxiliary mechanism in order to expose the stack of product.
