Abstract

Abstract A wrapping apparatus for soap bars and the like having a significantly increased production capacity. Product handling in a typical known wrapping device usually contemplates the feed movement of the product into the wrapping station incident to a cranking cycle, and thus a correspondingly restrictive production capability of a single product wrapping per operative cycle. In contrast, the apparatus hereof processes plural products for wrapping per operative cycle, thereby significantly increasing productivity. Increased productivity is attributable, in large measure, to a horizontal lift mechanism which during a single rotation of its rotary drive engages and transports plural soap bars to a wrapping station. In a noteworthy manner, the lifting surface of this mechanism is maintained in a necessary horizontal orientation throughout its 360* rotative traverse.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 245 words
A wrapping apparatus for soap bars and the like comprising an endless arrangement of product-holders operatively arranged for movement from above into a work station, two spaced-apart rotary members bounding opposite sides of said work station, a separate rotary axis for each said rotary member located a prescribed operative distance from each other, a cooperating pair of bearing mounting means operatively arranged said same prescribed operative distance from each other on each said rotary member at the same angular relation and distance from said rotary axis of each, a lift platform in straddling relation between said rotary members supported at said bearing mounting means, prime mover means for simultaneously driving said rotary means in rotation to thereby lift a product supported on said lift platform into holding engagement with one said product-holder, means dispensing wrappers, one at a time, in covering relation over each product during said lifting thereof into said holding engagement with one said product-holder such that said wrapper leading and trailing edges extend beyond opposite ends of said product in depending relation therewith, means urging said wrapper-covered product in feed movement through a wrapping station, a conveyor belt adapted to engage said wrapper-covereD product from below moving at a speed exceeding said feed movement effective to cause folding of said wrapper depending trailing edge against said product, and a folding abuttment located in the path of movement of said wrapper depending leading edge effective to cause the folding thereof against said product.
Claim 2
Dependent Claim 245 words
A wrapping apparatus for soap bars and the like comprising an endless arrangement of product-holders operatively arranged for movement from above into a work station, two spaced-apart rotary members bounding opposite sides of said work station, a separate rotary axis for each said rotary member located a prescribed operative distance from each other, a cooperating pair of bearing mounting means operatively arranged said same prescribed operative distance from each other on each said rotary member at the same angular relation and distance from said rotary axis of each, a lift platform in straddling relation between said rotary members supported at said bearing mounting means, prime mover means for simultaneously driving said rotary means in rotation to thereby lift a product supported on said lift platform into holding engagement with one said product-holder, means dispensing wrappers, one at a time, in covering relation over each product during said lifting thereof into said holding engagement with one said product-holder such that said wrapper leading and trailing edges extend beyond opposite ends of said product in depending relation therewith, means urging said wrapper-covered product in feed movement through a wrapping station, a conveyor belt adapted to engage said wrapper-covereD product from below moving at a speed exceeding said feed movement effective to cause folding of said wrapper depending trailing edge against said product, and a folding abuttment located in the path of movement of said wrapper depending leading edge effective to cause the folding thereof against said product.
Claim 3
Dependent Claim 170 words
A wrapping apparatus for soap bars and the like comprising an endless arrangement of product-holders operatively arranged for movement from above into a work station, two spaced-apart rotary members bounding opposite sides of said work station, a separate rotary axis for each said rotary member located a prescribed operative distance from each other, cooperating pairs of bearing mounting means operatively arranged said same prescribed operative distance from each other on each said rotary member at the same angular relation and distance from said rotary axis of each, plural circumferentially spaced lift platforms in straddling relation between said rotary members supported at said bearing mounting means, prime mover means for simultaneously driving said rotary means in rotation to thereby successively lift products supported on said lift platforms into holding engagement with each said product-holder, means dispensing wrappers, one at a time, in covering relation over each product during said lifting thereof into said holding engagement with said product-holder, and means urging said wrapper-covered product in feed movement through a wrapping station.
Claim 4
Dependent Claim 170 words
A wrapping apparatus for soap bars and the like comprising an endless arrangement of product-holders operatively arranged for movement from above into a work station, two spaced-apart rotary members bounding opposite sides of said work station, a separate rotary axis for each said rotary member located a prescribed operative distance from each other, cooperating pairs of bearing mounting means operatively arranged said same prescribed operative distance from each other on each said rotary member at the same angular relation and distance from said rotary axis of each, plural circumferentially spaced lift platforms in straddling relation between said rotary members supported at said bearing mounting means, prime mover means for simultaneously driving said rotary means in rotation to thereby successively lift products supported on said lift platforms into holding engagement with each said product-holder, means dispensing wrappers, one at a time, in covering relation over each product during said lifting thereof into said holding engagement with said product-holder, and means urging said wrapper-covered product in feed movement through a wrapping station.
