Abstract

A method includes separating a portion of a flattened tube of stock packing material to a custom length to form a pouch pre-form and closing a first end of the pouch pre-form leaving a second end of the pouch pre-form open. The method can include placing product into the pouch pre-form and closing the one open end of the pouch pre-form to form a closed pouch containing the product.

First claim

What is claimed is:

1. A system comprising:
a conveyor;
a separator;
a controller operatively connected to the conveyor and to the separator to control the conveyor to drive a custom length of a flattened tube of stock packaging material through the separator, and to control the separator to separate a custom length of the tube from the tube to form a pouch pre-from;
a first closer assembly operatively connected to the separator to receive the pouch pre-form, wherein the first closer includes:
a portion of a slide with retractable tines with an extended position for receiving the pouch pre-form from a cutter and to hold the pouch pre-form during erecting and closing one end of the pouch pre-form, and a retracted position for allowing a pre-form with one closed end to pass from the first closer assembly;
a closure plate parallel to the slide mounted for movement toward and away from the slide to press the pouch pre-form flat after erecting the pouch pre-form and applying adhesive to close one end of the pouch pre-form; and
an opposed pair of lateral plates extending along the slide on opposite sides of the closure plate mounted for movement relative to the slide to laterally to close inward on the pouch-preform to erect the pouch pre-form.

2. The system as recited in claim 1 , wherein the conveyor is a first conveyor and further comprising:
a second conveyor;
a filling station operatively connected to the first closer assembly and to the second conveyor to receive the pouch pre-form with one end closed from the first closer assembly and to receive orders of product from the second conveyor; and
a second closer assembly operatively connected to the filling station to receive pouch pre-forms with product therein from the filling station.

3. The system as recited in claim 2 , further comprising a sensor system operatively connected to controller and to the second conveyor to measure custom orders of product passing through the sensor system on the second conveyor and to control the first conveyor and separator to cut the custom length of the tube to fit each custom order of product.

4. The system as recited in claim 2 , wherein the separator includes:
a retractable holder mounted for movement relative to the slide to press the tube flat; and
a rotary knife mounted on a mechanism for traversing the flat tube to cut the custom length of the tube.

5. The system as recited in claim 2 , wherein the first closer includes:
an adhesive applicator mounted for lateral movement relative to the slide that is configured to apply adhesive to one end of the erect pouch pre-form prior to pressing with the closure plate to close a lower end of the pouch pre-form with respect to the direction of gravity.

6. The system as recited in claim 5 , wherein the filling station includes a pivot shuttle configured to receive the closed end of the pouch pre-form and flip the open end of the pouch pre-form away from the first closer.

7. The system as recited in claim 2 , further comprising a third conveyor operatively connected to the filling station to receive partially closed pouches with product therein and to convey the partially closed pouches away from the filling station.

8. The system as recited in claim 7 , wherein the third conveyor includes a labeler.

9. A system comprising:
a conveyor configured to drive a flattened tube of corrugated paper board;
a separator;
a controller operatively connected to the conveyor and to the separator to control the conveyor to drive a length of the flattened tube of corrugated paper board along a slide through the separator and then stop, and to control the separator to separate a length of the tube from the tube to form a pouch pre-from;
a first closer assembly operatively connected to the separator to receive the pouch pre-form, wherein the first closer includes:
a portion of the slide with retractable tines with an extended position for receiving the pouch pre-form from a cutter and to hold the pouch pre-form during erecting and closing one end of the pouch pre-form, and a retracted position for allowing a pre-form with one closed end to pass from the first closer assembly;
a closure plate parallel to the slide mounted for movement toward and away from the slide to press the pouch pre-form flat after erecting the pouch pre-form and applying adhesive to close one end of the pouch pre-form; and
an opposed pair of lateral plates extending along the slide on opposite sides of the closure plate mounted for movement relative to the slide to laterally to close inward on the pouch-preform to erect the pouch pre-form.
