Abstract

A wrapping machine for wrapping trayed food products includes a wrap station at which trayed food products are wrapped and a film dispensing system for drawing out film at the wrap station. A conveying system moves trayed food products through the wrapping machine. The machine may include a printer and label apply arrangement positioned for applying labels to trayed food products after wrapping, where the printer and label apply arrangement includes a support that is pivotable between an operating position and an access position. The film dispensing system may include a knife movable for cutting the film, and opposite ends of the knife are mechanically linked via spaced apart first and second belts to maintain alignment of the opposite ends.

First claim

What is claimed is:

1. A wrapping machine for wrapping trayed food products, comprising:
a wrap station at which trayed food products are wrapped;
a film dispensing system for drawing out film at the wrap station;
a conveying system for moving trayed food products through the wrapping machine;
a printer and label apply arrangement positioned for applying labels to trayed food products after wrapping, the printer and label apply arrangement including a support that is pivotable between an operating position and an access position;
wherein the printer and label apply arrangement includes a printer housing including an internal space for holding a label supply, wherein the printer and label apply arrangement includes a label applier external of the printer housing, wherein both the printer housing and the label applier pivot with the support when the support pivots, wherein the printer housing includes a movable door for label replacement, wherein the movable door is configured to pivot relative to both a part of the printer housing and the support for movement between open and closed positions.

2. The machine of claim 1 , wherein the machine includes a sensor arrangement for detecting when the support is in the operating position, and further comprising a controller associated with the sensor arrangement and configured to prevent wrap operations when the support is not in the operating position.

3. The machine of claim 2 wherein the controller is configured to output an error message on an operator interface of the machine when the support is not in the operating position.

4. The machine of claim 2 wherein the operator interface is mounted to the support for movement therewith during pivot of the support, and the operator interface is mounted to an arm that also pivots relative to the support.

5. The machine of claim 1 wherein the support is positioned over a sealer belt of the machine when in an operating position and pivots toward a front side of the machine when moving to the access position, the sealer belt running in a lateral direction of the machine.

6. The machine of claim 5 wherein wrapped packages feed onto one side of the sealer belt and a pivot axis of the support is located toward an opposite side of the sealer belt.

7. The machine of claim 1 , wherein the machine includes a latch for releasably holding the support in the operating position, wherein the latch is formed by a ball detent, wherein the ball moves with the support and the detent is stationary.

8. A wrapping machine for wrapping trayed food products, comprising:
a wrap station at which trayed food products are wrapped;
a film dispensing system for drawing out film at the wrap station;
a conveying system for moving trayed food products through the wrapping machine;
a printer and label apply arrangement positioned for applying labels to trayed food products after wrapping, the printer and label apply arrangement including a support that is movable between an operating position for label application and an access position for changing out a label supply;
wherein the printer and label apply arrangement includes a printer housing including an internal space for holding a label supply, wherein the printer housing includes a movable door for label replacement, wherein the movable door is configured to pivot relative to both a part of the printer housing and the support during movement between open and closed positions.

9. The wrapping machine of claim 8 , wherein the wrapping machine further includes at least one of:
a latch for releasably holding the support in the operating position; or
a sensor arrangement for detecting a position of the support; or
an operator interface mounted to the support for movement therewith.

10. The wrapping machine of claim 8 , wherein the wrapping machine further includes each of:
a latch for releasably holding the support in the operating position; and
a sensor arrangement for detecting a position of the support; and
an operator interface mounted to the support for movement therewith.

11. The machine of claim 10 , further comprising a controller associated with the sensor arrangement and configured to prevent wrap operations when the support is not in the operating position.

12. The machine of claim 8 , further comprising:
an output conveyor for receiving trayed food products that have been wrapped, the output conveyor including an associated sealer belt;
wherein, in the operating position, the support is positioned over the sealer belt;
wherein, in the access position, the support is pivoted to extend away from the sealer belt.

13. The machine of claim 8 , wherein the movable door faces and opens toward a rear side of the wrapping machine when the support is in the operating position.

14. The machine of claim 8 , further comprising:
an operator interface;
wherein the operator interface is mounted to the support for movement therewith.

15. A wrapping machine for wrapping trayed food products, comprising:
a wrap station at which trayed food products are wrapped;
a film dispensing system for drawing out film at the wrap station;
a conveying system for moving trayed food products through the wrapping machine;
a printer and label apply arrangement positioned for applying labels to trayed food products after wrapping, the printer and label apply arrangement mounted on a support frame that is pivotable between an operating position and an access position;
wherein the printer and label apply arrangement includes a printer mounted atop the support frame;
wherein the printer and label apply arrangement includes a label applier external of the printer and mounted on the support frame adjacent a label exit slot of the printer;
wherein both the printer and label applier pivot with the support frame.
