Abstract
The apparatus for cutting film tubing described herein is intended for use in a machine for applying tubular labels to each of a series of containers that are transported on a conveyor. The film tubing is advanced incrementally through a ring gear and a bore in a platform on which the ring gear is rotatably mounted. A number of pinions with attached cutting blades are rotatably mounted to the platform in positions to mesh with the ring gear. One of the pinions is driven to rotate a single revolution when the film tubing has been advanced. The driven pinion causes the additional pinions to rotate through rotation of the ring gear, causing the blades to cut the film tubing.
Claims19
In a machine for applying cut lengths of film tubing as tubular labels to products, an apparatus for cutting the film tubing, comprising:
- a. a platform having a bore formed therethrough;
- b. a ring gear having external teeth and a hole formed centrally therethrough positioned on the platform coaxially with the bore;
- c. a plurality of pinions rotatably mounted to the platform in positions to engage the teeth of the ring gear;
- d. a planar member assembled to overlie an area where the teeth of the ring gear engage teeth of selected ones of the pinions;
- e. a blade affixed to each of the plurality of pinions;
- and
- f. means for rotating one of the pinions.
An apparatus for cutting tubing to a desired length, comprising:
- a. a platform having a bore formed therethrough;
- b. a ring gear formed with external teeth and a hole therethrough rotatably positioned on the platform coaxially with the bore;
- c. a plurality of pinions rotatably mounted to the platform and arranged to mesh with the ring gear;
- d. a plurality of discs coaxially assembled to the plurality of pinions in a position for preventing the ring gear from moving axially;
- e. a blade affixed to each of the plurality of discs;
- and
- f. means connected for causing one of the plurality of pinions to rotate through a selected arc.
