| 摘要 | Device or apparatus for automatically unloading and loading spools, cops, bobbins, cores, tubes and the like carried by textile machine spindles, e.g., in rows or banks along the face of the machine, said device essentially including a movable framework carrying two different gripping means reciprocating in a linear and curved path, respectively, so as to rapidly unload and load the same spindle without mutual interference. The device is particularly useful in combination with double-twist twisting machines or similar machines equipped with twisting spindles in order to properly mount and assemble all of the spool and spindle elements in a rapid sequential operation. | ||||||
| 权利要求 | 1. A device for automatically loading and unloading spindles located at intervals along the face of a textile machine, said device comprising: a supporting framework movable along said machine face for the alignment of individual spindle positions; at least one first gripping means mounted on said framework for reciprocal linear movement axially of an individual spindle and including releasable clamping means for holding a spool being withdrawn from said spindle; at least one second gripping means separately mounted on said framework by a swinging lever arm for reciprocal motion in a curved path between an upper spool receiving position and a lower spindle registering position at which the spool is fitted onto said spindle, said second gripping means including releasable clamping means to hold a spool being transported from said upper position to said lower position; and means to separately actuate each of said first and second gripping means for cooperative movement with respecT to the same spindle such that said first gripping means is drawn away from said spindle while said second gripping means loads a spool onto said spindle and returns in said curved path free of interference with said first gripping means. 2. A device as claimed in claim 1 wherein said second gripping means reciprocates in a circular path between said upper and lower positions. 3. A device as claimed in claim 1 wherein said spindles are positioned at a plurality of levels along said machine face and all of said gripping means are mounted with means for adjusting their height independently of their reciprocating and clamping movements. 4. A device as claimed in claim 3 wherein said at least one first gripping means is arranged on a slide member for reciprocal movement on an approximately horizontal guide rail means which in turn is vertically adjustable on said framework for movement of said first gripping means between upper and lower spindle positions. 5. A device as claimed in claim 1 wherein the loaded spool contains at least one additional thread handling element projecting from the outer gripped end of the spool, said first gripping means including separately actuated and releasable gripping jaws, one of which clamps and holds the spool alone while the other clamps and holds said at least one additional element. 6. A device as claimed in claim 5 wherein said additional thread handling element includes a thread brake and a hollow tubular member for insertion of the thread. 7. A device as claimed in claim 5 wherein said additional thread handling element includes a rotatable flyer and said first gripping means has at least one deflecting means to swing the radially protruding vanes of said flyer into a position free of interference with the gripper clamping jaws. 8. A device as claimed in claim 1 including separately controllable hydraulic cylinder and piston means operatively linked to each of said gripping means to actuate their linear and arcuate reciprocal movement, respectively, said movements occurring in approximately the same plane which passes through the axis of the spindle being loaded. 9. A device as claimed in claim 1 wherein each gripping means includes paired clamping jaws of identical construction arranged in parallel and spaced at the same interval as the spindles being loaded. 10. A device as claimed in claim 1 including means mounted on said first gripping means to deflect thread guides from their normal position axially of the spindles during the replacement of spools on the spindles so as to avoid interfering with the loading operation. 11. A device as claimed in claim 1 including programming means for withdrawing a first spool from an individual spindle with said first gripping means, then partially fitting a second spool onto said spindle with said second gripping means, further releasing said first spool from said first gripping means at a position remote from said spindle and then completely fitting said second spool onto said spindle by engagement with said first gripping means being returned toward said spindle a second time in the same loading sequence. 12. A device as claimed in claim 11 wherein said first gripping means includes two separately actuated and releasable gripping jaws, one of which clamps and holds the spool alone until released at said position remote from said spindle, and the other of which clamps and holds at least one additional thread handling element adapted to project from the outer gripped end of the spool, said additional element first being clamped and held during the withdrawal and release of said first spool and then being reinserted onto said second spool by the return engagement of said first gripping means for completely fitting said second spool onto said spindle. |
