Description

AUTOMATIC RING (YARN MACHINE) SPINDLE STOPPER RELATED FIELD OF THE INVENTION This invention is related to a spindle stopper which stops the spinning spindle after yarn breakage. 5 PRIOR ART RELATED TO THE INVENTION On current ring yarn machines yarn is produced by winding the twisted strand on a tube which is on a revolving spindle. The spindle is revolving by the means of a driving belt which takes power from the main motor. If there is a yarn breakage for any reason, the spindle continues revolving. Meanwhile there is no yarn 10 production. Since there is no sign or system included to notice the breakage, the spindle revolves in vain (without any yarn production) until the operator comes to realize the breakage. With the yarn broken and the spindle continuing to spin; 15 - the yarn which was produced flows through a suction canal and goes to waste. Meanwhile until the operator joins the yarn by twisting, the spindle revolves without any yarn production. , since the yarn goes on revolving, the winding yarn on the tube with a free end causes cotton flies by rubbing against some parts of the machine. These cotton 20 flies are loss of production and cause yarn breakages on the same machine or on the other machines in the same room. Thus yarn breakage can cause more then one breakage and this increases the total number of breakages on the machine, In order to quickly take action to resolve the increased number of the breakages in a short time the number of operators around the machine must be increased since 25 the number of the operators are determined according to the expected number of the breakages. - when the number of the breakages exceed the expected number, the speed of machines is decreased resulting in the loss of production in order to make the machines run efficiently, or operators work overtime to deal with less machines 30 than usual to solve the problem. - operators stop the spindles by lifting or lowering spindle brakes by their knees or hands manually (according to the type of machines) in order to allow them to twist the yarn again. -1- THE AIMS OF DEVELOPING OF THE INVENTION Objectives; - to stop the revolving spindle immediately when there is a yarn breakage, 5 . to prevent other yarn breakages caused by broken yarn's cotton flies, - to run the ring machine faster , - to decrease the number of operators per machine, - to increase the efficiency (by increasing the productivity), - to reduce costs, 10 BRIEF SUMMARY OF INVENTION Accordingly, in one broad form of the invention, there is provided a spindle stopping mechanism for a yarn machine comprising: a minimum of one yarn breakage sensor for each spindle of said yarn machine, 15 a magnetic field coil assembly including a coil housing attached to a main connection part; said magnetic field coil assembly energized when yarn breakage is detected on any spindle, an inserting metal piece which is drawn into the magnetic field coil when said magnetic field coil is energized, 20 a stopping arm connected to said inserting metal piece, a locking mechanism including a weight moving in unison with movement of said inserting metal piece; movement of said weight causing a locking mechanism part to drop down a T canal in said stopping arm so as to lock said stopping arm into a spindle clamping position, and 25 wherein the movement of said metal piece causes the stopping arm to engage and stop a said spindle on which yarn breakage occurred. Preferably, the spindle stopping mechanism is characterized by a magnetic field coil comprising; a coiled part (2), an exterior part of the coiled part (3), a rear box which covers the magnetic field coiled wires (5) and a box cover. -2- Preferably, the spindle stopping mechanism is characterized by having plastic top on the head of said inserting metal piece; said inserting metal piece able to move forward and backward in the magnetic field of said magnetic field coil assembly.

Preferably, more than one said magnetic field coil, inserting metal piece (6), 15 stopping arm (7) and locking mechanism (8 and 9) are provided. Preferably, the movement of said inserting metal piece (6) is guided by the help of an exterior part of the coil housing (3). Preferably, the spindle stopping mechanism is further characterized in that energy driving said spindle is cut when said locking mechanism is activated. 20 Preferably, the said locking mechanism is manually released to allow the yarn spinning process to continue.

The magnetic field created by an energizing coil (2) causes the inserting metal (7) to move. 15 Inserting metal (6) has a plastic top (14). This plastic top (14) is to protect it from dust. The inserting metal moves forward and backward inside the magnetic field. When there is a magnetic field, the inserting metal (6) is pulled inside by this magnetic field causing the stopping arm (7) to squeeze the spindle. The locking mechanism which is shown on the Figure 12, consists of plastic part (8) 20 and preferably ball-shaped metal weight (9). The locking mechanism is connecting to a stopping arm (7) which moves in unison with the movement of inserting metal (6). When the stopping arm (7) moves, the metal weight (9) causes the locking mechanism part (8) to drop down the T canal (12) and thus mechanically lock the brake in an applied condition. During this time the energy is cut off. 25 The movement of the stopping arm (7) which is shown on the Figure 11 causes the rear connection part arms (11) to squeeze the spindle and thus stop the spindle. These parts are assembled by the ring machine's producers on the stopping arm (7). The Main connection (1) is a metal component which is used to assemble the ring 30 machine spindle stopper to the ring machine. The parts which are mentioned above are assembled on to the main connection part (1) (Figures 1 ,2,3,4 and 5). -5- These parts are assembled to the ring machine after joining together on the main connection part (15). Connection component (15) which is a plastic part with canals and bolt holes on it is a mechanism to allow the other components assembled to the machine. 5 Breakage sensors which are used to yarn breakages during the production of yarn on the ring machine work by detecting the speed of the traveller (Travellers make the yarn wind up on to the tube). For traveller's speed higher than 2400 RPM, no information is sent to the main board. If the speed is below the limit 2400 RPM, a break is indicated and information is sent to the main board. 10 Based on this information the main board energize the coil as warranted to stop the spindle. When energized, the now magnetized coil pulls the inserting metal into the coil. Since the stopping arm (7) is attached to the inserting metal (6) its movement causes, the locking system (Figure 12) to move through the T canal on the stopping arm and lock the spindle. Meanwhile the energy of the system is cut 15 off, and the system works by the method of mechanical locking. An operator can then repair the yarn system on this spindle, and then release the metal weight (9) in order to allow the yarn twisting process to continue. In this case the brake mechanism to it's original state since the magnetic field is no longer energized. -6-
