Abstract

A cans exchanging system whereby, out of cans arranged in plural rows in the longitudinal direction of a spinning frame, plural empty cans arranged in the direction orthogonal to the longitudinal direction of the spinning frame are carried out from the rows of cans, and plural full-loaded cans are carried in simultaneously to the carried-out position of the empty cans. A sliver piecing device for piecing together slivers, from sliver feeding cans to a spinning machine and slivers from full-loaded cans while carrying both cans on a cans exchanging carrier is mounted on the cans exchanging carrier.

Claims

1. A cans exchanging system, comprising:

a plurality of cans arranged in an array with a plurality of rows in the longitudinal direction of a spinning machine and a plurality of columns in a direction orthogonal to the longitudinal direction of the spinning machine,

one of said columns being empty cans arranged in the direction orthogonal to the longitudinal direction of the spinning machine,

means for carrying out simultaneously said empty cans in said one of said columns,

a plurality of full-loaded cans, and

means for carrying in simultaneously said plurality of full-loaded cans to said one column which was the carried-out position of the empty cans.

2. A cans exchanging system as claimed in claim 1, further including sliver guides disposed above and provided for each of said cans arranged in said array of rows and a single sliver guide shaft disposed in the longitudinal direction of the spinning machine upon which said sliver guides are mounted.

3. A cans exchanging system as claimed in claim 2, wherein said single sliver guide shaft disposed in the longitudinal direction of the spinning machine upon which said sliver guides are mounted is disposed above a substantially middle portion between adjacent said cans in each of said columns.

4. A cans exchanging system, comprising:

a plurality of cans arranged in a plurality of rows in the longitudinal direction of a spinning machine,

a plurality of empty cans arranged in a direction orthogonal to the longitudinal direction of the spinning machine,

means for carrying out simultaneously a plurality of said plurality of empty cans,

a plurality of full-loaded cans,

means for carrying in simultaneously said plurality of full-loaded cans to a carried-out position of the empty cans, and

means for forming a gap between said empty cans and a floor and a can transfer device which is inserted into the gap to take out the empty cans.

5. A cans exchanging system as claimed in claim 4, wherein said means for forming a gap is a tilting means wherein a plurality of said plurality of said empty cans arranged in a direction orthogonal to the longitudinal direction of the spinning machine are tilted to form said gap between the tilted cans and the floor, and wherein said can transfer device is insertable into said gap between the tilted cans and the floor, and wherein after the cans are moved back from the tilted state to the original state, said can transfer device is able to be drawn out in the direction orthogonal to the longitudinal direction of the spinning machine.

6. A cans exchanging system as claimed in claim 5, wherein said can transfer device comprises a can resting member and a moving member disposed below the can resting member, and said can resting member and said moving member are movable in a direction orthogonal to the longitudinal direction of a spinning machine.

7. A cans exchanging system as claim in claim 5, wherein said can resting member and said moving member are movable telescopically in a direction orthogonal to the longitudinal direction of a spinning machine, and means for moving aid can transfer device down along downwardly inclined guide rails toward the spinning machine.

8. A cans exchanging system as claimed in claim 5, wherein said can transfer device includes a tilting member, an intermediate moving member disposed on the tilting member and a can resting member disposed on the intermediate moving member, and a rack member attached to the intermediate moving member which is engaged with a chain disposed on the tilting member.

9. A can exchanging system as claimed in claim 8, wherein a plurality of spinning machines are installed, a tilting means for tilting said tilting member is attached to the can transfer device, and said can transfer device is capable of being moved to anywhere along a spinning machine adjacent thereto.

10. A cans exchanging system as claimed in claim 5, wherein said cans exchanging system further includes a can presser member capable of moving forward and backward in a direction orthogonal to the longitudinal direction of the spinning machine.

11. A can exchanging system as claimed in claim 10, wherein said can presser member includes a pair of urging members capable of rising and falling, transferring members to which said urging members are mounted, and a common drive source for synchronously driving said transferring members.

12. A sliver piecing method characterized in that a can which is feeding sliver to a spinning machine and a full-loaded can are placed on a cans exchanging carrier provided with a sliver piecing device, and the sliver from the sliver feeding can and that from the full-loaded can are pieced together on the cans exchanging carrier.

13. A sliver piecing method, comprising the steps of:

drawing out a predetermined amount of an old sliver from a can which is feeding sliver to a spinning machine,

then slackening said old sliver from said old can, and

thereafter piecing together said old sliver from said can and a new slaver from a full-loaded can.

14. A silver piecing system, comprising:

an old silver from a can which is feeding sliver to a spinning machine,

a new sliver from a full-loaded can on a cans exchanging carrier provided with a sliver piecing device,

means for drawing out and slackening said old sliver from the sliver feeding can on the cans exchanging carrier prior to piecing the old and new sliver with the sliver piecing device.

15. A sliver piecing system, comprising:

an old sliver from a can which is feeding sliver to a spinning machine,

a new sliver from a full-loaded can on a cans exchanging carrier provided with a sliver piecing device,

means for drawing out and slackening said old sliver from the sliver feeding can on the cans exchanging carrier prior to piecing the old and new sliver with the sliver piecing device; and

wherein said sliver piecing means includes piecing members for nipping said old sliver from said can which is feeding sliver to the spinning machine and said new sliver from said full-loaded can, and fixing nip members and fixed nipping bases each arranged in the vertical direction and nipping said old sliver from the sliver feeding can and said new sliver from the full-loaded can;

said piecing member, said fixing member and said fixed nipping base being positioned approximately orthogonal to each other in the respective longitudinal directions.

16. A sliver piecing system, comprising:

an old sliver from a cam which is feeding sliver to a spinning machine,

new sliver from a full-loaded can on a cans exchanging carrier provided with a sliver piecing device,

means for drawing out and slackening said old sliver from the sliver feeding can on the cans exchanging carrier prior to piecing the old and new sliver with the sliver piecing device; and

wherein said means for drawing out and slackening the old sliver includes a sliver guide, a sliver draw-up member, and a draw-up roller which is disposed at an end portion of the sliver draw-up member, said sliver draw-up member being hold between rollers driven by a motor capable of rotating forward and reverse.
