Below, the main action that has the Yarn-end treating device of said structure with reference to Fig. 5 and Fig. 6, explanation.

At first, by the known brake that does not have expression among the figure pallet t that is placing the bobbin b that is wound with loose thread y that sends along the path v that advances is stopped, the bobbin that makes bobbin b be in the front end of the above-mentioned piston rod 3 ' that is provided in vertical oil cylinder 3 is controlled the below of member c.

Then, make that vertical oil cylinder 3 suitably move, this vertical oil cylinder 3 is that conduct makes bobbin control mobile device that member c moves, action by oil cylinder 3 makes bobbin control member c decline, and importing guide member 4 and chuck 6 are inserted in hole, the top b1 of bobbin b, after this by chuck 6 is expanded, control bobbin b (referring to Fig. 5 (a) and Fig. 6 (a)) by chuck 6.

Then, vertical oil cylinder 3 is suitably moved, thereby making bobbin control member c rises, thus bobbin b is dialled from the protruding nail t ' that erectly is arranged on the pallet t, and make the bottom of bobbin b that bobbin handle part c is risen.

Follow, make chuck 6 to shrink, make vertical oil cylinder 24 actions, thus piston rod 24 ' be moved upward, thereby a pair of sliding

shoe

14a, 14b are moved towards mutual direction of closing along guide rail 12a, 12b.Mobile, clamp 17a, the 17b such by sliding

shoe

14a, 14b also move towards mutual approaching direction, in bottom importing recess 18a, the 18b with bobbin b, and the bottom (with reference to Fig. 5 (b) and Fig. 6 (b)) of clamping bobbin b by a pair of

clamp

17a, 17b.

Under the state of clamping by a pair of

clamp

17a, 17b in the bottom of bobbin b, when making vertical oil cylinder 3 suitably move, make bobbin to control member c decline once more, the loose thread y that will be wound on the bobbin b by the member 23a of spring hangs over the peeling on sheet 21a, the 21b on the slide plate 20a that be installed in that is urged on bobbin b side face, and loose thread y is peeled from bobbin b.The decline that the bobbin b that loose thread y is peeled controls member c with bobbin with maintaining the original state descends, and is inserted into the protruding pin t ' that erectly is arranged on the pallet t once more and goes up (with reference to Fig. 5 (c) and Fig. 6 (c)).

Clamp

17a, 17b be in contact with one another or near the time, by depressed portions 18a, the 18b of

clamp

17a, 17b form that bobbin b can pass through, as the roughly rounded space d of the flat shape of bobbin path.And make bobbin control the push rod 7 of member c, be provided in importing guide member 4 on the push rod 7 and chuck 6 can insert logical this as the space d of bobbin by portion, and vertical oil cylinder 3 can make bobbin control member c to move between upper position and lower position; Upper position is meant is controlled the position nearby that the bottom of the bobbin b on the member c is positioned at clamp members G being held in bobbin, and lower position is meant and is controlled bobbin b on the member c and be placed on pallet t and go up the position being held in bobbin.Like this, no matter loose thread y be wound on bobbin b which partly go up, can both positively loose thread y be removed.

After the bobbin b that loose thread y is peeled is placed on the pallet t,, vertical oil cylinder 3 is suitably moved, thereby make bobbin control member c when rising, chuck 6 is transferred to from hole, the top b1 of bobbin b.Revert near the clamp members G or during position of readiness above the clamp members G, the action of vertical oil cylinder 3 is stopped bobbin being controlled member c.

Because the loose thread y that peels from bobbin b is by a pair of

clamp

17a, 17b is placed into clamp 17a, top or the adjustment plate 22a of 17b, above the 22b, thereby by the folder 17a, the loose thread that 17b makes is removed in the operation or after loose thread removes operation, make executive component 11 actions, thus switch mouth 10 is opened, make and produce row attraction air flow in the attraction mouth 9 ' that attracts member S, and air is sprayed from the nozzle 8 ' of aerojet member N, air by nozzle 8 ' ejection will be placed on clamp 17a, above the 17b or adjust plate 22a, loose thread y above the 22b blows out, and is sucked by the attraction mouth 9 ' facing to the attraction member S that disposes.The loose thread y that is inhaled into 9 li of suction tubes is deposited into the loose thread of not representing among the figure and deposits in the case by behind the switch mouth 10.After such loose thread processing finishes, switch mouth 10 is closed, make aerojet member N stop action simultaneously.Like this, just finish the loose thread processing operation of Yarn-end treating device.

Though be that the structure that sets attraction member S and aerojet member N that clamp members is clipped in the middle is an example in the above-described embodiments, but under the bigger occasion of the ability in the attraction source that attracts member S, since only with attract member S just can be placed on clamp 17a, above the 17b or adjustment plate 22a, loose thread y attraction above the 22b remove, thereby at this moment just can omit aerojet member N.
