Definitions
- a retractable stop is mounted in the trackway at a position such that the car, or series of cars, is stopped with its reaction tube out of contact with powered drive rollers mounted on a movable frame in the track.
- the powered drive roller frame is shiftable lengthwise so that it may be moved from its idle position (rollers intennediate the reaction tubes of stopped cars) to an active position where the rollers engage the reaction tubes.
- the drive roller frame is interconnected with the arresting means or stop so that the operations are synchronized.
- FIG. I is a plan view of a section of track including a stop and movable power drive means with arrested cars shown in phantom.
- FIG. 2 is a side elevation of the section of track.
- FIG. 3 is an enlarged side elevation of a stop for arresting the cars as seen from the line 33 ofFIG. 1.
- FIG. 4 is a vertical section of a movable frame carrying car drive means as seen from the line 4-4 of FIG. 1.
- FIG. 5 is a schematic layout of a car-holding area in which a car stop and movable drive means may be employed.
- the improved accumulating and dispensing station comprises a length of track 1 which may be part of the trackage of a holding or car storage area.
- the track 1 comprises, along its sides, angle irons 2, 3 on which loadbearing wheels 4 of a luggage carrier or car is adapted to run.
- each of the cars 5 has a reaction tube 6 extending lengthwise of the car and joumaled for rotation about its longitudinal axis.
- the reaction tube 6 cooperates with drive rollers 7 mounted at intervals along the track and set at angles corresponding to the speed at which the car is to travel past a particular drive wheel.
- Each of the drive wheels 7 is provided with its own drive motor 8. These motors may be constant speed induction motors since the speed of the car is controlled by varying the angle between the axis of the drive wheel and the track.
- the drive rollers 7 with their individual motors 8 are mounted on a longitudinally extending frame 10 that is carried on rollers 11 joumaled in brackets 12 attached by crossties 13 of the track.
- the frame 10 is guided laterally by rollers l5 mounted on the top of the ties 13 in position to engage the inner sides of angle irons 16 making up the longitudinal members of the frame 10.
- guard rollers 17 mounted from the crossties l3 and overlying the flanges of the angle iron I6.
- the frame 10 is reciprocated lengthwise by means of an air cylinder 20 mounted on a bracket attached to the crosstie 13.
- An hydraulic cylinder may be used instead of an air cylinder if desired.
- the air cylinder 20 is controlled through air lines 21, 22 from an electrically operated valve mechanism 23 which in turn is controlled by an electrical control line 24 from a photoelectric control circuit housed in a control box 25.
- a photocell 26 of the circuit is mounted on a pipe 27 erected from the crosstie I3 in position to receive light from a light source 28, similarly mounted, as long as there is no car interrupting the light path.
- the control energizes the air cylinder 20 to drive the frame 10 toward the left, as shown in FIG. 1, and the frame 10 through a connecting link 30 pivotally connected to a downwardly extending arm of a stop bracket 31 rotates the bracket about its pivot axis 32 to bring its stop plate 33 into position to meet the bumper of a car 5 and arrest the car.
- the pivot axis 32 of the stop bracket 31 is carried on fixed arms 34 erected from a tie 13.
- the drive rollers 7 are spaced apart along the frame 10 at intervals equal in length to the length of the cars 5. This is true except that the drive roller 7 adjacent the stop mechanism may be positioned a little closer to its adjacent drive roller inasmuch as the car is accurately located in position at that point. The important thing is that the drive rollers 7 are located so as to not engage the rotatable reaction tubes 6 of the stopped cars. Thus, as shown in FIG. 2, the leftmost drive roller 7 is located intermediate the stop and the left end of the adjacent cars reaction tube 6 while the drive rollers 7 remote from the stop are located substantially midway between the adjacent ends of the drive reaction tubes 6 of the following cars.
- FIG. 5 shows a typical plan layout of the track paths through a holding or parking area and, as shown, comprises an incoming track 40, a series of parallel siding or parking tracks 41 and an exit track 42.
- Each of the siding tracks 41 is provided with a frame 10 including drive motors 8 and arranged under the controls of an air cylinder or hydraulic cylinder 20 which in turn is responsive to the controls of the overall system.
- Any idle cars in the system are directed into the holding area and enter on the track 40 from which they are switched on to a selected one of a siding tracks 41 according to the number of cars already in the area.
- a car entering a siding 41 travels along the siding until it either encounters a preceding car already in the siding or until it engages the stop 33 near the end of the siding.
- the stop is located just before a curve leading into the merging switches leading to the exit track 42.
- An in coming car coasts from the time its reaction tube 6 leaves one drive wheel 7 until it engages the next drive wheel.
- This preferred embodiment of the invention provides means for automatically causing the incoming cars to creep into position in line on each of the sidings, the siding being selected by switching means not shown, and to be held in position on such siding until required for further use in the system. Furthermore, the cars are automatically advanced on each siding as the leading cars are withdrawn and automatically disengaged from the drive power when they reach the parking position.
- means for controlling the movement of cars past a holding station comprising power drive means, means mounting the power drive means for reciprocation between a first and a second position along the track, a member in each car that engages the drive means throughout a portion of the car's travel past a point in the track and that is free of the drive means during the remainder of its travel past the point, said power drive means and said member cooperating to produce relative motion between the drive means and the car.
- a stop mounted in the track for arresting a car when its member is free from the drive means and the drive means is in its first position, means for withdrawing the stop, and means for moving the power drive means along the track to its second position at which it engages the member of the stopped car and drives the car.
- a system according to claim 1 comprising a mechanical linkage connecting the stop means to the means for moving the power drive means.
- a system according to claim 1 having the drive means adjacent the stop arranged to drive a car at a substantially higher speed than the remaining drive means.
- a movable frame in which the power drive means are mounted at intervals generally equal to the overall length of a car.
- power means responsive to a demand signal connected to said movable frame and said stop for withdrawing the stop and for moving the frame to car drive position.
- means for generating a clear signal as a car passes the withdrawn stop means for generating a clear signal as a car passes the withdrawn stop, and means responsive to a no demand signal and the clear signal for returning said stop to car arresting position.
- the power drive means comprise drive wheels joumaled in a frame and the member engaging the drive wheels comprises a longitudinally extending tube extending lengthwise of the car and journaled for rotation about its axis.
