Abstract
Apparatus for opening and closing twist finger assemblies for wrapping candies and similar products. Two twist fingers are symmetrically pivoted to a forked end portion of a rotating and axially sliding sleeve, and each finger has an extension radial with respect to its pivot, in the forked end of the sleeve. A slidable rod extends through the sleeve and to adjacent the pivots of the fingers. Two links are provided in the forked end portion of the sleeve; each of them has one end articulated to a common pivot pin at an end of the rod, and has another end articulated to an end of the extension of the finger.
Claims7
A twist finger device, comprising;
- a pair of fingers, each having a gripping member rigid therewith and disposed to be alternately (a) in a gripping position closely adjacent the gripping member of the other finger for gripping tubular wrap portions of candies and similar products between the gripping members to twist the gripped wrap portions and (b) in a releasing position spaced from the gripping member of the other finger, each finger also having an actuator member extending therefrom and rigid therewith;
- a pair of pivot pins, one for each finger, pivotally supporting the finger and located, parallel to one another between the gripping and actuator members of the finger;
- a sleeve having an end portion supporting the pivot pins to support the fingers;
- a rod slidably mounted in the sleeve for controlling the fingers and having an end portion which extends to a location adjacent the pivot pins;
- means for rotation of the sleeve and rod;
- a pair of links, each articulated at one point thereof to the end portion of the rod and at another point thereof to the actuator member of one of the fingers;
- and
- means for reciprocatingly sliding the rod relative to the sleeve during their rotation for pivoting the fingers about the pivot pins by the links articulated to the rod and the actuator members, to alternately place the gripping members of the fingers in the gripping and releasing positions, an acute angle being defined, in a plane at right angles to the pivot pins, by (1) a line from the pivot pin of each finger to the point where the respective link is articulated to the finger's actuator member, and (2) a line from the latter point to the point where the respective link is articulated to the end portion of the rod, when the gripping members of the fingers are in the gripping position.
