Abstract
A pin rope control device, in which the pulley provided for the rope is completely free to rotate at all times without any mechanical engagement of the pulley at any time. Remote movement sensing devices are provided along side the pulley, which detect movement of the pulley and deliver a predetermined sequence of signals. Suitable circuitry is provided to receive the sequence of signals, and to activate the rope tensioning motor to reset the pins. In one embodiment, a magnet is mounted to rotate in unison with the pulley and actuate in sequence a pair of stationarily mounted reed switches to trigger operation of the motor. In a second embodiment, the sensing device is in the form of a photocell.
Claims13
A pin rope control for use in motorized pin setting apparatus wherein said pins are attached to ropes, said control comprising;
- supporting means;
- a pulley wheel mounted thereon around which a said rope runs in both forward and reverse directions, said pulley wheel being freely rotatable in either direction in response to any movement of said rope either in the forward or reverse direction and being free of any interruption by any other means thereby permitting the pulley wheel to stop at any random position in response solely to said rope and permitting said pulley to start rotation freely without restraint in response to movement of said rope, and,
- remote sensing means free of any mechanical connection with said pulley and responsive only to movement of said pulley wheel from any random at rest position to generate at least one signal, said signal being operative to trigger operation of said motorized pin setting apparatus and said remote sensing means being inoperative to trigger such operation while said pulley wheel is at rest.
A pin rope control for use in motorized pin setting apparatus wherein pins are attached to ropes, said control comprising;
- a pulley freely mounted for rotation without mechanical interruption, said rope running over said pulley, said pulley being free to come to rest at any rotational position thereby insuring free running of said pulley;
- mounting means for supporting said pulley in a desired location;
- magnet means mounted for rotation in unison with said pulley, and at least two magnetically sensitive means mounted in fixed relation to said pulley adjacent to the circular path of movement of said magnet means, proximity of said magnet means to said magnetically sensitive means operating the same and initiating signals, and,
- circuit means connected to said magnetically sensitive means for receiving signals therefrom and operable to trigger said motorized pin setting apparatus after said pulley has moved from a random at rest position in response to a signal from a said magnetically sensitive means subsequent to the first such magnetically sensitive means, and before it has completed one revolution.
A pin rope control for use in motorized pin setting apparatus wherein pins are attached to ropes, said control comprising;
- a pulley freely mounted for rotation without mechanical interruption, said rope running over said pulley, said pulley being free to come to rest at any rotational position thereby insuring free running of said pulley;
- mounting means for supporting said pulley in a desired location;
- photo sensitive signal generating means, a light source therefor, establishing a light path to said photo sensitive means, the same being mounted in fixed relation relative to said pulley as aforesaid, and including light interrupter means rotatably mounted in association with said pulley for rotation in unison therewith, and passing through said light path, whereby to interrupt passage of light to said photo sensitive means upon rotation of said pulley, thereby generating signals responsive to such rotation, and,
- circuit means connected to said signal generating means for receiving signals therefrom and operable to trigger said motorized pin setting apparatus after said pulley has moved from a random at rest position, and before it has completed one revolution.
A pin rope control for use in motorized pin setting apparatus wherein said pins are attached to ropes said control comprising;
- supporting frame means;
- a pulley wheel freely mounted thereon for rotation without mechanical interruption, said rope running over said pulley, said pulley being free to come to rest at or start from any random rotational position;
- remote sensing means supported on said frame means in fixed relation adjacent said pulley for sensing the rotational position of said pulley without mechanical contact therewith, and independently of the at rest position of said pulley;
- remote actuating means on said pulley for actuating said remote sensing means and operable to deliver at least two impulses thereto in sequence responsive to at least two rotational positions of the pulley, and,
- circuit means connected to said remote sensing means and responsive to an impulse subsequent to the first such impulse to trigger said motorized pin setting apparatus after said pulley has moved from a random at rest position, and before it has completed one revolution, and being inoperative in response to the first such impulse.
