An automatic, moveable manipulator includes an arm supported on a carriage and holding at least one tool. Both the arm and the carriage can be moved under the control of signals transmitted from a remote location, such as a central controller, which signal is stored in a storage device. The manipulator further supports a reservoir for holding materials that can be used by the tool, for example to apply to the workpieces, such as fluids, fasteners, expendable materials, and the like. An automatic resupply system permits the manipulator to re-fill the reservoir, such as when it is emptied.

A low power consumption type tape reader permits miniaturization of reel motors and ensures stopping a tape (3) at a first rewind stop code, even if the response of a brake magnet (11) is somewhat poor. When a rewind command is received, the rotational speed of a capstan motor (12) is switched from a forward low speed to a reverse low speed, and then a feed magnet (14) is actuated to rewind the tape (3). The rotational speed of the capstan motor (12) is gradually increased to a reverse high speed. When a rewind stop code is detected, the speed of the capstan motor (12) is gradually decreased to the reverse low speed, and then the brake magnet (11) is actuated to stop the feed of the tape (3) temporarily. A reversible counter (40) stores the number of rewind stop codes detected during the time interval between the detection of the first rewind stop code and the temporary stopping of the feed of the tape (3). After the tape (3) has stopped, the speed of the capstan motor (12) is switched to the forward low speed. When the forward low speed is reached, the feed magnet (14) is actuated to feed the tape (3) in the forward direction, and the number of detected rewind stop codes is subtracted from the contents of the reversible counter (40). When the contents of the reversible counter becomes zero, the brake magnet (11) is actuated to stop the feed of the tape (3).

For recording instruments fed from a 50 Hz or 60 Hz supply mains it is proposed to use a control unit of substantially entirely digital structure for the transport of the record carrier, for example paper, with the use of a stepping motor. A simple 300 Hz or 600 Hz oscillator which is synchronized with the mains and a frequency divider enable various paper speeds to be set, slow or fast paper transport for adjusting purposes being simply realized by controlling the frequency of the oscillator. Several functions can be remotely controlled.

A system for automatically unwinding paper tape from a roll and feeding it to the output punch of a tape justifying computer. A 14-inch roll of tape without a reel is mounted upright on a hub on the outer wall of a soundproof housing enclosing the output punch. A pair of manually operable retainer members on the end face of the hub swing between inner release positions and outer effective positions to hold the tape roll in place. A roller on a pivoted arm rides on the tape roll and the traveling tape from the roll is turned 90* in direction to a tape drive on the same housing wall, the tape drive feeding the tape to the tape punch inside the housing. The housing comprises a bottom wall and a separate removable box-like shell. The tape punch engages locating pins on the bottom wall and the shell interlocks with the bottom wall in proper relationship thereto for positioning the roll of tape and the tape drive on the housing shell accurately relative to the tape punch inside the housing.

A machine tool tape control includes an endless tape coil rotatably contained in a cassette casing which is mounted directly below the tape-reading head of the machine in an upwardly and outwardly inclined position such that an external loop of the tape leaves the inside of the coil, emerges through a medial slot in the rear side of the casing, and extends directly upwardly to the reading head and thence downwardly and back into the casing through an end opening therein, from which it extends tangently to the periphery of the roll and is wound externally thereon.

A magazine is provided for receiving, storing a stack of and delivering successive sections of a long endless belt of flexible photoconductive sheet material which is pre-folded in zigzag manner for use in indirect electrophotographic copying processes. Oppositely disposed upright guide walls which, in downward direction, converge inwardly to a delivery opening between their lower ends define a storage space holding a large number of the zigzag-folded belt sections stacked one upon another in upwardly bowed postures with their respective folds disposed on opposite portions of the guide walls, so that a length of the belt extending through a processing path from the ends of the stack may easily be drawn continuously from the bottom thereof and redeposited in zigzag folds onto the top thereof. Successive folds entering the top of the magazine are alternately disposed on and pressed down along the opposite guide walls. Threshold members at the delivery opening and/or resilient members bearing elastically against opposite sides of the stack aid in maintaining the folded belt sections in the required upwardly bowed postures.
摘要:
A tape handling device for a tape processing machine having a punch tape unit from which the tape is expelled. An upper take-up reel driven by a motor drive is rendered operative under the control of a tape tension switch. Magnetic means releasably hold reels on the upper and lower reel shafts. The motor drive is reversible and variable in speed for tape take-up and rewind purposes.

A commuter wheel is mounted on a threaded shaft between two pulleys. The pulleys are free to rotate on the shaft but are braced against movement along the axis of the shaft. The direction of shaft rotation determines which pulley is driven by the commuter wheel. The device is used to wind and rewind a tape between two spools.

A tape-punching apparatus including a source of tape, a punching mechanism, a drive to draw tape from the source and make the same available in a loop to the punching apparatus, a further drive to transport the thusly looped tape from the loop through the punching device, and detection means which senses the tension in the loop from which tape is driven by the second drive through the punching device. The detection means is effective to actuate the first-mentioned drive to replenish the loop when required. A brake is provided which is responsive to the detection means to apply a braking force to the first-mentioned drive to avoid coasting of the same and thus to avoid an oversupply of tape to the loop.

The specification and drawings disclose a lock for detachably mounting a tape reel hub to a drive shaft in which a conical plug is drawn into a conical slot in the hub forcing the plug upwardly so that a flat surface on the plug tightly engages a corresponding flat surface on the motor drive shaft.
