Claims
- 1. A packaging machine comprising:
- a) a base section;
- b) an upstanding support section mounted on the base at a location offset to one side of the base;
- c) a web supply positioner connected to the base and in cantilever relationship with the support section and projecting laterally above the one side of the base section toward the other side of the base section cantilever fashion;
- d) a web dispensing section mounted on the support section above the positioner and projecting laterally from the support section toward the other side of the base section cantilever fashion; and
- e) web path delineating elements carried by at least one of the sections to delineate a path of web travel from the supply positioner to the dispensing section.
- 2. The machine of claim 1 wherein the dispensing section is rotatively mounted on the support and a clamp means is interposed between the dispensing and support sections to fix the dispensing section in a rotatively adjusted position.
- 3. The machine of claim 1 wherein the support section includes an internal chamber and the support section provides at least a portion of an air manifold.
- 4. The machine of claim 3 wherein the dispensing section mounting is a tube having another internal chamber communicating with the support chamber to define a further portion of the air manifold.
- 5. The machine of claim 1 wherein the dispensing section is a bagger.
- 6. A packaging machine for loading products into bags that are fed through the machine in a web in the form of a continuous chain of bags, the machine defining a web path of travel and comprising:
- a) a base;
- b) a support section connected to the base;
- c) a bagger mounted on the support section;
- d) electronic control means for controlling the machine;
- e) an input module connected to the support section and electrically connected to the bagger for allowing operator input to the electronic control means; and
- f) the bagger being pivotable relative to the support section.
- 7. The packaging machine of claim 6 wherein the input module is pivotable.
- 8. The machine of claim 6 wherein a portion of the support section includes an internal chamber and the support section provides at least a portion of an air manifold.
- 9. The machine of claim 7 wherein the bagger is mounted on said portion of the support section by a tube having another internal chamber communicating with the internal chamber of the support section to define a further portion of the air manifold.
- 10. A packaging machine for loading products into bags that are fed through the machine in a web in the form of a continuous chain of bags, the machine defining a web path of travel and comprising:
- a) a base;
- b) a support section connected to the base;
- c) a bagger mounted on the support section;
- d) the support section defining an internal chamber forming at least a portion of an air manifold; and,
- e) an inlet to said internal chamber for connecting the internal chamber to an external air supply source.
- 11. The machine of claim 10 wherein the bagger is connected to the support section via a tube that defines another internal chamber portion that communicates with the support chamber portion to define an extension of the air manifold.
- 12. A packaging machine for forming packages from a web of preopened bags comprising:
- a) a base for supporting the machine above a support surface;
- b) an upstanding tubular column connected to and supported by the base, the column defining an internal chamber;
- c) a tubular, bagging mechanism support connected to the column and extending laterally cantilever fashion over the base, the support including an internal space communicating with the chamber;
- d) the column and the support together having walls supporting fluid fittings and being otherwise imperforate such that the chamber and the space together form an air plenum;
- e) a web supply positioner connected to the column and projecting cantilever fashion over the base and beneath the support; and,
- f) a bagging mechanism mounted on the support, the mechanism including web feed structure for feeding such web of interconnected bags received from a supply supported by the positioner to a loading station.
- 13. The packaging machine of claim 12 wherein the web feed structure comprises:
- a) a first pair of grooved rolls;
- b) a first set of elastic belts reeved about the first pair of rolls to form a first web conveyor with the belts, each having a web feed reach extending between the rolls along a path of travel and opposed return reaches;
- c) a second pair of grooved rolls;
- d) a second set of elastic belts reeved about the second pair of rolls to form a second web conveyor with the belts, each having a web feed reach extending between the rolls along a path of travel and opposed return reaches;
- e) first rolls of each pair being abutting nip rolls at the downstream ends of the feed reaches;
- f) second rolls of each pair being an upstream set with the second rolls of the first pair being downstream from the second roll of the second pair;
- g) the feed reaches of the first conveyor being located in an imaginary plane; and,
- h) the second roll of the second pair being, at least in part, on the same side of such imaginary plane as the return reaches of the first conveyor such that the feed reaches of the second conveyor are deflected over and engage surfaces of the second rolls of the first pair.
- 14. The packaging machine of claim 13 wherein the grooves of the nip rolls each have radial depths greater than the thickness of the belt disposed in that groove as measured radially of its roll.
- 15. The machine of claim 12 wherein the bagging mechanism is rotatably mounted in the support and a clamp is operatively interposed between the mechanism and a selected one of the support and the column to fix the mechanism in rotatively adjusted positions on the support.
- 16. The machine of claim 12 wherein an electronic input module is carried by the column.
- 17. The machine of claim 16 wherein the module is rotatively mounted on the column and a clamp is interposed between the module and the column for securing the module in an adjusted position.
