- the mechanism for latching the, barrel in a retracted position and for unlatching the barrel includes ball detents within apertures inthe wall of the barrel.
- An axially translatable stern withinthe barrel has ,two portions of different diameters. One portion of the stem urges the ball detents outwardly into a recess in the housing to lock or latch the barrel in a retracted position and the other portion of the stem is of smaller diameter to permit the ball detents to be urged inwardly to disengage from the recess to unlatch the barrel.
- FIG. Ia is a diagrammatic representation of FIG. Ia
- FIG. 2 20 1 I4 I I I I I I I I I I REMOTE 'ALL CUT SWITCH 71 1 THREAD CUTTING AND CLAMPING MEANS
- This invention relates to a yarn cutting and clamping mechanism which may be employed in yarn or thread manufacturing and/or processing, and in textile mills where yarn and thread is worked into cloth and material.
- the invention also includes novel means for controlling the operation of one or more such mechanisms.
- the present invention is an electromechanical thread or yarn cutting and clamping mechanism which is relatively simple in construction, is positive in its operation, and involves simple electrical circuitry which utilizes an electromagnet only to unlatch a mechanism which is in a set condition.
- the mechanism utilizes energy stored in a spring to provide the cutting and clamping force. thereby permitting the use of a relatively small electromagnet.
- the present invention also includesmeans for simultaneously operating a plurality of cutting and clamping mechanisms upon command from a remote location. This latter operation may be performed independently of the conditions of the strands of thread.
- FIGS. 1 and 2 are sectional views showing the essential features of the mechanism of this invention in, respectively, its set .or latched condition and in its unlatched or extended condition;
- FIG. la is a sectional view of the latching mechanism of this invention.
- FIG. 3 is a simplified wiring diagram used in explain ing the electrical connection and operation of one and of a plurality of the mechanisms illustrated in FIGS. 1 and 2.
- a strand of yarn, thread. or the like is received within guidesll and 12 in respective side walls of'a substantially hollow or box-like housing 14.
- Guides 11 and 12 are open at the top surface of housing 14 so that strand 10 may be easily inserted therein so as to span the inner region of the housing.
- Housing 14 may be formed from molded plastic members.
- a cutting anvil 16 having a hardened surface 17 is secured to the left end wall of housing 14.
- a pad 20 of elastomeric material' such as rubber or a plastic.
- pad 20 may be secured by an adhesive to or latching handle 25, FIG. la, is secured to barrel 24 and extends outwardly through an elongated slot 13 in housing 12.
- the left end of barrel 24 is provided with cutting edge 26 and with a clamping surface 27 which is set back from cutting edge 26.
- cutting edge 26 strikes hardened surface 17 of cutting anvil 16, thereby cutting strand 10.
- clamping surface27 holds a severed end of strand 10 against elastomeric pad 20, thereby clamping that end of the strand in fixed positron.
- Barrel 24 is provided with two apertures 30 and.3l which extend through its wall.
- Ball detents 33 and 34 are received within apertures 30 and '31 and are free to move radially therein but are held against any significant longitudinal movement relative to barrel 24.
- Balls 33 and 34 may be inexpensive metal ball bearings.
- Recess 36 has a sharp shoulder 38 against which balls 33 and 34 are urged to set v or latch the mechanism, as will be explained in more detail below.
- a stem 40 is disposed coaxially within hollow barrel 24 and is axially translatable with respect to the barrel.
- stem 40 includes three cylindri cal portions of different diameters.
- the center or first portion 41 is proportioned so that it is in close, yet freely slidable, contact with the inside surface of hollow barrel 24.
- the second portion 42 at the left end of stem 40 is smaller in diameter than the first portion 41.
- the diameters of the first and second stem portions 41 and 42 are proportioned relative to the diameter of balls 33 and 34, the wall thickness of barrel 24, and the depth of recess 36 so that in the set or latched condition illustrated in FIG.
- balls 33 and 34 are in contact with the surface of first stem portion 41, and with the bottom and shoulder 38 of recess 36. In the latched position, balls 33 and 34 should extend beyond the outer surface of barrel 24 by a distance which is approximately equal to one-third their diameters. Although this distance is not critical, it always should be less than one-half the diameters of the balls.
- the proportioning of the abovementioned parts relative to each other also is chosen so that in the released condition of the mechanism illustrated in FIG. 2, balls 33 and 34 are in contact with the I surface of the second stem portion 42 and so that the FIG. la, which joins the first and second stem portions 41 and 42.
- Transition section 43 must be constructed and proportioned to assure that as .stem 40 translates from right to left relative to balls 33 and 34 the transi-
- the right end of stem 40 is comprised of an armature 45 of magnetic material which functions with solenoid 46, when the latter-is energized, to move the entire stem 40 to the right.
- Solenoid 46 is firmly secured to housing 14 by any suitable means.
- Armature 45 is of greater diameter than the first portion 41 of stem 40 so as to form a shoulder 48 against which the right end of barrel 24 abuts, as illustrated in FIG. 1.
- a light helical spring 49 is disposed between the end of armature 45 and a support within solenoid 46 to urge stem 40 toward the left to maintain shoulder 48 in butting contact with the right end of barrel 24, as illustrated in FIG. 1.
- a second and stronger helical spring 50 is disposed about armature 45 and is held in compression between the reduced diameter right end of barrel 24 and a tubular member 51 within solenoid 46.
- Spring 50 provides an axial force tending to urge barrel 24 toward the left.
- the force exerted by spring 50 against barrel 24 is significantly greater than the relatively light force exerted by spring 49 against stem 40.
- spring 50 supplies the force for translating barrel to its extreme left-most position illustrated in FIG. 2 in which cutting edge 26 cuts strand on anvil 16.
- the left end of spring 50 is fashioned into a straight actuator pin 52 which extends downwardly so that it may engage and depress the contact button 55 of a three terminal, single pole, double throw electrical snap switch 56. As will be explained only two contact connections are actually wired into the operating circuitry.
- a second electrical switch 60 has a long actuating lever 61 which is in engagement with the strand of thread 10 when the strand is in its desired taut condition illustrated in FIG. 1.
- switch 60 When actuator arm 61 is in contact with a taut strand, switch 60 is held in its open position by the strand.
- actuator arm 61 moves to cause a pair of contacts of switch 60 to close and initiate a cutting and clamping operation.
- Switch 60 and its lever arm 61 thus function as a thread tension sensor.
- Tension sensing switch 60 also may be a three contact, single pole, double throw snap switch.
- a small neon bulb 65 is included in housing 14. As will be explained below, bulb 65 is lighted when the mechanism is in its extended or clamping position illustrated in FIG. 2 to provide a visual indication that the mechanism has transferred from its normally set condition.
- First portion 41 1/16 inch diameter.
- Second portion 42 A inch diameter.
- Armature 45 3/16 inch diameter.
- switch 60 is in a condition to maintain solenoid 46 unenergized, an attendant or operator grasps latching handle and moves it to its right-most position within slot 13, thus sliding barrel 24 and spring 50 to their respective positions illustrated in FIG. I.
- the small spring 49 urges shoulder 48 on armature 45 up against the right end of barrel 24 so that ball detents 33 and 34 are urged outwardly by the first stem portion 41 into contact with outermost portions of circular rccess 36.
- Balls.33 and 34 now are clear of shoulder 38 and spring 50 pushes barrel 24 to the left with a snap-like action to cause cutting edge 26 to cut strand 10 on anvil 16 and to cause holding surface 27 to hold the severed end of strand 10 against pad 20.
- Neon bulb 65 is caused to glow when the mechanism is in the condition illustrated in FIG. 2. The mechanism will remain in this condition until reset by an attendant.
- FIG. 3 is a simplified system wiring diagram for a plurality of N devices of the type illustrated in FIGS. 1 and 2. Only devices I, 2, and N of a large plurality are illustrated, and since all devices are identical, only device 1 now will be described, using the same reference numerals corresponding to components illustrated in FIGS. I and 2.
- the conditions of switch 56 and tension sensing switch 60 are for the set or latched condition of the mechanism illustrated in FIG. 1, assuming the strand 10 is under tension in its desired taut condition.
- the movable contact arm of tension sensing switch 60 is held against the normally open (NO) contact by reason of lever arm 61 being held up by taut thread 10.
- Movable contact arm 55 of switch 56 is held in contact with the normally closed (NC) contact. Solenoid 46 is not energized by the 1 10V a.c.
- the resiskiloohms so as to limit the current flowing through so lenoid 46 and neon bulb 65. This value of current is insufficient to maintain solenoid 46 in an energized state, so that the small spring 49 may move armature 45 and stem 40 to the left, away from the solenoid. Neon bulb 65 continues to glow until the mechanism is reset.
- FIGS. 1 and 2 many of the cutting and clamping mechanisms illustrated in FIGS. 1 and 2 may be employed.
- a plurality of the mechanisms of this invention be operated to cut the thread or yarn and hold the free end independently of the operation of the tension sensing switch 60. This may be accomplished by the use of a remote all cut? switch 71 illustrated in FIG. 3.
- Switch 71 is connected in series between power line 67 and a shunting line 75. Line 75 is connected by way of leads 72, '73, 74 to the normally open (NO) contacts of the tension sensing switches 60 of the respective mechanisms 1, 2, N.
- the mechanism of this invention is simple in construction, provides a positive latch and a positive release of the mechanism, and by utilizing energy stored in spring 50 to supply the cutting and clamping force, a relatively smallelectromagnet may be utilized to provide only an unlatching force. Further, simple electrical circuitry is employed to afford alternative operational capabilities.
