Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
216 words
An apparatus for removing projecting drinking straws from empty bottles comprising: a. a supporting frame structure, b. a conveyor for the bottles either in a case or individually, c. at least one pair of endless straw-gripping belts adapted for movement above said conveyor, d. a plurality of spaced pairs of pulleys mounted at predetermined position on said frame structure for guiding said belts over a series of stretches as follows: i. a straw-gripping stretch which extends generally parallel relative the bottle conveyor and in which said belts approach each other closely as they approach the top of the bottles whereby the belts clamp said projecting straws between them; ii. a straw-removing stretch which extends generally upwardly relative the bottle conveyor and in which said belts move together in close juxtaposition and remove said straws from said bottles; iii. a straw-holding stretch which extends generally normal to and then substantially parallel to the bottle conveyor and in which the belts are close together and hold said straws between them, and iv. a straw-ejecting stretch which extends generally normal relative the bottle conveyor and in which said belts are separated to release said straws; e. means to separate said belts in said last-mentioned stretch, said last-mentioned stretch joining at its end with the beginning of the first-mentioned stretch.
Claim 2
Independent Claim
216 words
An apparatus for removing projecting drinking straws from empty bottles comprising: a. a supporting frame structure, b. a conveyor for the bottles either in a case or individually, c. at least one pair of endless straw-gripping belts adapted for movement above said conveyor, d. a plurality of spaced pairs of pulleys mounted at predetermined position on said frame structure for guiding said belts over a series of stretches as follows: i. a straw-gripping stretch which extends generally parallel relative the bottle conveyor and in which said belts approach each other closely as they approach the top of the bottles whereby the belts clamp said projecting straws between them; ii. a straw-removing stretch which extends generally upwardly relative the bottle conveyor and in which said belts move together in close juxtaposition and remove said straws from said bottles; iii. a straw-holding stretch which extends generally normal to and then substantially parallel to the bottle conveyor and in which the belts are close together and hold said straws between them, and iv. a straw-ejecting stretch which extends generally normal relative the bottle conveyor and in which said belts are separated to release said straws; e. means to separate said belts in said last-mentioned stretch, said last-mentioned stretch joining at its end with the beginning of the first-mentioned stretch.
Claim 3
Dependent Claim
17 words
An apparatus as claimed in claim 1 wherein said means are two pulleys spaced from each other.
Claim 4
Dependent Claim
35 words
An apparatus as claimed in claim 1 wherein the pairs of pulleys are individually mounted on a shaft mounted on said supporting structure generally normal to the direction of movement of the said bottle conveyor.
Claim 5
Dependent Claim
21 words
An apparatus as claimed in claim 1 wherein the pairs of pulleys are formed on a roller mounted on a shaft.
Claim 6
Dependent Claim
35 words
An apparatus as claimed in claim 1 wherein a plurality of groups of pairs of belts are provided to remove the straws from a plurality of bottles conveyed in a transverse row below said belts.
Claim 7
Dependent Claim
27 words
An apparatus as claimed in claim 1 wherein the pair of pulleys located at the end of said straw-gripping stretch are elastically mounted on said frame structure.
Claim 8
Dependent Claim
19 words
An apparatus as claimed in claim 1 including means for centering the bottles between said belts on said conveyor.
Claim 9
Dependent Claim
20 words
An apparatus as claimed in claim 1 including means for centering the straws between said belts in said straw-gripping stretch.
Claim 10
Dependent Claim
50 words
An apparatus as claimed in claim 7 wherein said means for centering the bottles comprise mountings for the pulleys at the beginning of said straw-gripping stretch in external bearings which are fixed with respect to the frame structure, and guide means provided on said bearings between the pairs of pulleys.
Claim 11
Dependent Claim
80 words
An apparatus as claimed in claim 8 wherein the means for centering the straws between the belts comprise pairs of sheet metal guides fixed to the said frame structure and having vertical parts which are spaced from each other by substantially the width of a bottle neck and bent-over portions under which the said belts run and which approach each other in the direction of travel of the belts to be in close juxtaposition at the end of said stretch.
Claim 12
Dependent Claim
23 words
An apparatus as claimed in claim 1 including spring-tensioned means provided for the mounting of one of the series of pairs of pulleys.
Claim 13
Dependent Claim
46 words
An apparatus as claimed in claim 1 wherein the belts in said straw-removing stretch are disposed an angle α with the horizontal as follows: tan α = (h/l) wherein h is the height of the bottles and l is the length of a case of bottles.
Claim 14
Dependent Claim
47 words
An apparatus as claimed in claim 12 wherein the relative speeds of said bottle conveyor and said pairs of belts is expressed as follows: V.sub.2 = V.sub.1 cos α wherein V 1 is the speed of the belts and V 2 is the speed of the conveyor.
