Abstract
Abstract An apparatus for transferring yarns in hanks from hank carriers or supports movable along a feeding line to a container or conveyor device comprises a head (40) movable in at least one direction parallel with the extension of the hank holding supports (11) and preferably movable also parallel with the feeding of the hank holders; the head carries at least one pliers member (50) comprising two parallel rods (51, 52) cantilevered and movable between a spread apart position and a position close to each other.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
185 words
A device for hank transfer from hank holding supports movable along a feeding line to a containing or transporting device, each of the hank holding supports having a generally horizontally extending portion for supporting a hank, said device comprising: a head with at least one pliers member formed of a pair of rods extended substantially parallel with an extension of the horizontally extending portion of the hank holding supports, said rods being movable between a widened out or opening position and an approached closing or gripping position; means for controlling the movement of said rods between said opening and closing positions; and means for displacing said head with pliers at least in a direction parallel with an extension of the horizontally extending portion of the hank holding supports so that said rods in said opening position are positionable on opposite sides of a hank supported on one of said hank holding supports and are thereafter movable to said closing position to grip the hank so that the hank is removable from said holding support by displacement of said head away from the hank holding support.
Claim 2
Independent Claim
185 words
A device for hank transfer from hank holding supports movable along a feeding line to a containing or transporting device, each of the hank holding supports having a generally horizontally extending portion for supporting a hank, said device comprising: a head with at least one pliers member formed of a pair of rods extended substantially parallel with an extension of the horizontally extending portion of the hank holding supports, said rods being movable between a widened out or opening position and an approached closing or gripping position; means for controlling the movement of said rods between said opening and closing positions; and means for displacing said head with pliers at least in a direction parallel with an extension of the horizontally extending portion of the hank holding supports so that said rods in said opening position are positionable on opposite sides of a hank supported on one of said hank holding supports and are thereafter movable to said closing position to grip the hank so that the hank is removable from said holding support by displacement of said head away from the hank holding support.
Claim 3
Dependent Claim
25 words
A device according to claim 1, further comprising means for moving said head in a direction parallel with the feeding of said hank holding supports.
Claim 4
Dependent Claim
60 words
A device according to claim 1, wherein said means for controlling the movement of said rods comprises two spindles, a supporting arm for one of the rods integral with each spindle, said spindles being rotatably mounted on said head, gear wheels each integral with one of said spindles, each gear wheel meshing with a respective rack sliding on the head.
Claim 5
Dependent Claim
14 words
A device according to claim 3, wherein said racks move as a unitary body.
Claim 6
Dependent Claim
80 words
A device according to claim 1, wherein said means for displacing said head comprises first sliding guides extending parallel with the extension of the horizontally extending portion of the hank holding supports for guiding movement of said head, carriage means for carrying said first sliding guides, and said device including second sliding guides extending parallel with the feeding of the hank holding supports for guiding movement of said carriage means, and fixed frame means for carrying said second sliding guides.
Claim 7
Dependent Claim
100 words
A device according to claim 1, wherein said means for displacing said head comprises first sliding guides extending parallel with the extension of the horizontally extending portion of the hank holding supports for guiding movement of said head, and frame means for carrying the first sliding guides; said device including second sliding guides extending parallel with said first sliding guides for guiding movement of said frame means and slide means for carrying said second sliding guides; said fixed sliding guide means extending parallel with the direction of movement of said hank holding supports for guiding movement of said slide means.
Claim 8
Dependent Claim
32 words
A device according to claim 3, wherein said means for controlling movement of said rods comprises a cylinder-piston unit mounted on said head and having a movable member connected to said racks.
Claim 9
Dependent Claim
17 words
A device according to claim 1, wherein said means for displacing said head comprises a cylinder-piston unit.
Claim 10
Dependent Claim
40 words
A device according to claim 2, wherein said means for moving said head comprises a reducing motion variator or speed changer enabling a feed movement of said head at the same speed as the movement of the hank holding supports.
Claim 11
Dependent Claim
29 words
A device according to claim 1, comprising on a single head two pliers spaced apart from each other by the same spacing as that between successive hank holding supports.
Claim 12
Dependent Claim
14 words
A device according to claim 1, wherein said rods are parallel with one another.
Claim 13
Dependent Claim
11 words
A device according to claim 1, wherein said rods are convergent.
Claim 14
Dependent Claim
18 words
A device according to claim 1, wherein said rods have reliefs or teeth facing along the extension thereof.
Claim 15
Dependent Claim
13 words
A device according to claim 1, wherein said rods have a terminal bending.
Claim 16
Dependent Claim
13 words
A device according to claim 1, wherein said rods have a curvilinear shape.
Claim 17
Dependent Claim
36 words
A device according to claim 1 for hank transfer between hank holding supports of two facing chains, characterized by comprising means for synchronizing the chain movements and for ensuring the alignment of respective hank holding supports.
Claim 18
Dependent Claim
25 words
A device according to claim 1, wherein said rods substantially extend in the same direction as the hank supporting portion in a hank holding support.
Claim 19
Dependent Claim
17 words
A device according to claim 1, wherein said rods substantially extend as two aligned hank holding supports.
Claim 20
Dependent Claim
29 words
A device according to claim 1, comprising on a single head two pliers spaced apart from each other by a multiple of the spacing between successive hank holding supports.
Claim 21
Independent Claim
182 words
A device for transferring hanks from hank holding supports moving in a feeding direction, said hank holding supports having a horizontally extending portion supporting the hanks, said device comprising: a pair of rods movable with respect to each other between a spaced apart position and a gripping position in which the distance between the rods is less than the width of a hank carried by one of said hank holding supports; means for controlling movement of said rods between said spaced apart position and said gripping position; head means for supporting said rods and said means for controlling movement of said rods; and first movement means for moving said head means to and fro in a first direction parallel to an extension of said horizontally extending portion of said hank holding supports so that said rods in said spaced apart position are located on opposite sides of a hank supported on one of said hank holding supports and so that said rods after being moved to said gripping position are moved away from the hank holding support to thereby transfer the hank.
