Abstract
Abstract A textile machine is provided with a movable transport conveyor having Casablanca pins which convey packages on bobbins and a support member located in the path of movement of the bobbins for release of the bobbins from the pins. The support member serves to push the bobbins relative to the pins in order to effect a release of the bobbins from the pins. In addition, the support member cooperates with a transport conveyor which permits the released packages to be taken off to further processing equipment.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
111 words
In combination a conveying means having a plurality of spaced apart pins for engaging and conveying bobbins in a suspended manner through a predetermined path having an upper run and a lower run, each said pin being adapted to release an engaged bobbin therefrom upon pushing of the bobbin onto said pin; and a support member located in said path at a release position between said upper run and said lower run for abutting a free end of each successive bobbin to cause each bobbin moving from said upper run to said lower run to move towards said respective pin for release of the bobbin from engagement with said respective pin.
Claim 2
Dependent Claim
111 words
In combination a conveying means having a plurality of spaced apart pins for engaging and conveying bobbins in a suspended manner through a predetermined path having an upper run and a lower run, each said pin being adapted to release an engaged bobbin therefrom upon pushing of the bobbin onto said pin; and a support member located in said path at a release position between said upper run and said lower run for abutting a free end of each successive bobbin to cause each bobbin moving from said upper run to said lower run to move towards said respective pin for release of the bobbin from engagement with said respective pin.
Claim 3
Dependent Claim
31 words
The combination as set forth in claim 1 which further comprises a transport means adjacent said support member to receive a bobbin disengaged from a respective pin of said conveying means.
Claim 4
Dependent Claim
15 words
The combination as set forth in claim 2 wherein said transport means is a slide.
Claim 5
Dependent Claim
23 words
The combination as set forth in claim 3 wherein said slide is pivotally mounted to tilt under the weight of a received bobbin.
Claim 6
Dependent Claim
23 words
The combination as set forth in claim 3 which further comprises a brake for braking the descent of a bobbin on said slide.
Claim 7
Dependent Claim
28 words
The combination as set forth in claim 1 wherein said support member is spaced from said conveying means to define a narrowing for the bobbins in said path.
Claim 8
Dependent Claim
38 words
The combination as set forth in claim 6 which further comprises a stationary support mounting said support member thereon and an abutment secured to said support in said path for engaging each respective bobbin in said release position.
Claim 9
Dependent Claim
46 words
The combination as set forth in claim 7 wherein said conveying means is endless and said upper run and lower run are disposed in vertical alignment to define a half-circular shaped portion in said path and said support member is disposed beneath said half-circular shaped portion.
Claim 10
Dependent Claim
39 words
The combination as set forth in claim 1 wherein said support member is stationary to abut the free end of a conveyed bobbin for subsequent release of the bobbin from a respective pin upon movement to said release position.
Claim 11
Dependent Claim
127 words
In combination an endless conveying means having a plurality of spaced apart pins for engaging and conveying bobbins for forming thread packages thereon through a predetermined endless path; and an endless band below said conveying means, said band having an upper run defining a narrowing for the bobbins in said path and movable at a greater speed than said conveying means, said upper run being located in said path at a release position for abutting a lower end of a package to cause each bobbin to move upwardly towards said respective pin for release of the bobbin from engagement with said respective pin, said band having a portion downstream of said narrowing extending away from said conveying means to transport bobbins thereon in a laid down position.
Claim 12
Dependent Claim
127 words
In combination an endless conveying means having a plurality of spaced apart pins for engaging and conveying bobbins for forming thread packages thereon through a predetermined endless path; and an endless band below said conveying means, said band having an upper run defining a narrowing for the bobbins in said path and movable at a greater speed than said conveying means, said upper run being located in said path at a release position for abutting a lower end of a package to cause each bobbin to move upwardly towards said respective pin for release of the bobbin from engagement with said respective pin, said band having a portion downstream of said narrowing extending away from said conveying means to transport bobbins thereon in a laid down position.
Claim 13
Dependent Claim
15 words
The combination as set forth in claim 10 wherein each pin is a Casablanca pin.
