Definitions
- This invention relates to filament severing devices, and more particularly to devices for automatically severing a filament when the filament becomes knotted and tangled or broken.
- one of the objects of this invention is to provide a novel and improved device for severing a filament or threadline.
- Another object of this invention is to provide a device for automatically severing a filament in response to a signal.
- a further object of this invention is to provide a device having a pair of scissors-like blades for automatically severing a filament when a fault is detected therein.
- One of the embodiments of this invention contemplates an automatically operated filament-severing device having a first blade mounted on a frame and a second blade pivotally mounted on the first blade.
- a solenoid connected to the second blade is provided for actuating the blades to sever a. filament passing therebetween.
- a first blade is mounted on the frame and a second blade, pivotally attached to the first blade, is spring-loaded toward cooperation with the first blade.
- a solenoid is provided for actuating a locking bar to release the second blade when a defect is detected in the filament.
- FIGURE 1 is a front view of a device illustrating the principles of the invention with part of the housing cut away to show the general relationship of the various parts;
- FIGURE 2 is a sectional view taken along line 2-2 of FIGURE 1 showing the positioning of a pair of cutting blades;
- FIGURE 3 is a front view of a second embodiment of the invention showing a spring-loaded blade in its cocked or loaded position
- FIGURE 4 is a sectional view taken on line 44 of FIGURE 3 showing the relationship of the cutting blades.
- a housing or frame 11 supporting a pair of spaced guides '12 which are provided for guiding a filament or threadline 13 along a predetermined path past the housing or frame 11. Slots 14- and 15 in the housing 11 and the guides 12, respectively, are provided for insertion of the filament 13 into the guides.
- a bolt 17 secured to the frame 11 extends through a spacer block 18 and a first blade 19 for securing the first blade to the frame 11.
- the first blade 19 is secured to the frame 11 near the midpoint of the first blade.
- the free or cutting end of the first blade 19 extends past the path of the filament 13 and 1s limited in its upper movement by a stop 20 which is secured to the frame '11. In operation, the blade 19 does not move. However, its position may be adjusted by loosening the bolt 17.
- a second blade 23 is pivotally secured to the first blade 19 by a pin 24 at the end of the blades.
- the free end of the second blade 23 extends past the path of the filament 13 on the lower side thereof.
- the second blade is free to drop of its own weight into a normal position below the path of the filament 13.
- a solenoid 26 attached to the frame or housing 11 is connected to the second blade 23 by a link 27 which is pinned to the solenoid plunger and to the second blade 23. It can be seen that energization of the solenoid 26 will raise the second blade 23 from its normal resting position into cooperation with the first blade 19 to sever the filament or yarn 13.
- the solenoid 26 is energized in response to a signal from some other part of the machinery or apparatus, indicating that a defect has been detected in the filament 13.
- One such apparatus for controlling the operation of a solenoid 26 is disclosed in copending application Serial No. 70,038, filed November 17, 1960, in the names of William H. Hills and Don E. Fisher for Yarn Crimping Apparatus. Since the blade 23 drops to its normal position (FIG. 1) when the solenoid is deenergized, no cocking or resetting of the device is necessary after the filament has been cut.
- a housing or frame supports a pair of spaced guides 36 which are provided for directing a filament 37 along a predetermined path through the frame or housing 35.
- a bolt 40 extends through the frame or housing 35 and serves as a support for a first blade 41, which has a free cutting end extending past the filament on one side thereof.
- a bolt 42 serves to pivotally attach a second blade 46 to the first blade 41 near the midpoint of the blade 41.
- the blades 41 and 46, a steel spring 47, an arm 4-8 and a fil ament-holding blade 49 are all keyed together by the bolt 42.
- a spring 50 secured to the frame 35 and to a bar 51 welded to the arm 48 is provided for moving the filamentholding blade 49, the spring 47, the arm 48 and the second cutting blade 46.
- the filament-holding blade 49 is so positioned that it engages the filament 13 and pinches it against the dull side of the first blade 41 before the filament is cut by the cooperating blades 41 and 46. This insures that the filament will be under tension when out.
- the end of the bar 51 extends from the frame or housing 35 to serve as a handle for manually moving the second blade 46 into its cocked or loaded position.
- the second blade 46 is held in its cocked or loaded position by a stop 53 on a locking bar 54 pivotally attached to the bolt 40.
- the stop 53 engages a tang 61 on the arm 48.
- a spring 55 secured between the frame 35 and the locking bar 54 urges the locking bar into engagement with a stop 56 secured to the frame 35.
- a solenoid 60 secured to the frame 35 is provided for pivoting the locking bar 54- counterclockwise to release the tang 61 on the upper end of the arm 48 from the stop 53, whereupon the spring 50 snaps the second blade 46 counterclockwise into cooperation with the first blade 41 to sever the filament as described above.
- a second stop 63 on the locking bar 54 is provided for engaging the tang 61 on the arm 48 to limit movement of the second blade.
- the operator grasps the bar 51 and pivots the arm 48 and the elements keyed thereto clockwise until the tang 61 passes the stop 53.
- the stop 53 will now hold the second blade 46 in its cocked or loaded position until the solev) noid 60 is energized to pivot the locking bar 54 counterclockwise.
