  • Patent number: 10666171
    Abstract: A motor system includes a motor, and a multi-turn absolute encoder that detects a rotation number and an absolute angular position of a rotation shaft of the motor. The multi-turn absolute encoder includes: an absolute angular position detection device that detects the absolute angular position within one rotation period of the rotation shaft; and a storage element that stores the rotation number of the motor. Even if the driving of the multi-turn absolute encoder is stopped while the motor is stopped, the multi-turn absolute encoder detects the multi-turn position of the rotation shaft after startup. Further, the motor has a brake mechanism including: a gear-type brake wheel that rotates integrally with the rotation shaft; an engagement member capable of engaging with the teeth of the gear-type brake wheel; and an actuator which causes the teeth and the engagement member to engage with each other during braking.

  • Patent number: 10506121
    Abstract: An image-reading device is provided that includes a reading component configured to read a document, a document holding portion, a detector detecting a position of the document holding portion, a power supply device that supplies power to the reading component, and a power supply control device that controls power supplied by the power supply device to the reading component. The power supply control device determines whether a change in the position of the document holding portion has occurred based on the position of the document holding portion detected by the detector. When a change in position is detected and the image reading device is not performing document reading, the power supplied to the reading component is reduced. If a change in position is detected while the image reading device is performing document reading, the power supplied to the reading component is maintained.

  • Publication number: 20150060510
    Abstract: A transfer and dispensing apparatus is disclosed for the conveying and separation of packaging material, cushions or pillows when needed by the operator. When a packer working over a conveyor receives a box that requires void fill, an operating switch such as a foot pedal is depressed to dispense pillows from the apparatus and into the box in a connected strip. When the operating switch is released, the apparatus stops dispensing pillows, separates the continuous strip of pillows along a transverse perforation in the strip, and ejects the end of the separated segment. The packer can then complete packing the box by placing the severed end of the pillows into the box, advance to the next box, and repeat the process. The transfer and dispensing apparatus may be positioned in any convenient location including adjacent to, above or attached to the inflation device.

  • Patent number: 6857546
    Abstract: In a double type tape feeder in which two tape feed mechanisms that pitch-feed carrier tapes holding electronic components are arranged in parallel and two carrier tapes can be simultaneously supplied, sprockets in the tape pitch feed mechanisms are arranged so that they hold a shaft axis in common, and directions of respective rotary shafts of motors are coincided with each other toward the shaft axis, so that the motors are arranged in radial pattern. Hereby, an overlap of widthwise sizes of the motors in plane arrangement is permitted. Therefore, the whole width size is reduced and a compact tape feeder is realized.

  • Patent number: 6851593
    Abstract: A system and method for controlling the strain of a web material supplied to a machine by adjusting a tension force applied to the web material. An operator defines a target web strain via an input device. A speed sensor senses the speed of the web material supplied to the machine at a first position and a second position and generates a speed signal representative of the difference. A tension sensor senses a tension force applied to the web prior to the first position and after the first position and generates a tension signal representative of the difference. A control system calculates web strain as a function of the tension signal and speed signal, and compares the calculated strain with the target web strain and generates a speed control signal as a function of the comparison. The feed device is responsive to the speed control signal for adjusting a speed differential of the web to adjust tension force applied to the web.

  • Patent number: 6834787
    Abstract: A feeding device for taped electric components includes advancing wheels for the tapes. The advancing wheels are driven via tangentially disposed drive spindles of a worm drive. Drive motors for the drive spindles are off-set from one another in two directions of the coordinate system in such a manner that their distance in the axial direction of the advancing wheels is smaller than the distance of the advancing wheels. This thereby allows an increase of the thickness of the drive motors and a corresponding increase of their drive power.

  • Patent number: 6830172
    Abstract: A method of and apparatus for feeding string from a supply involves entraining the string around at least one feed roll and driving the feed roll continuously in cycles in a direction for feeding the string forward. Each of the cycles involves varying the speed of the roll for feeding a predetermined length of string forward per cycle. The string is subjected to a force in the reverse direction upstream from the feed roll and to a force in the forward direction downstream from the feed roll.

  • Patent number: 6817507
    Abstract: A capstan motor for a magnetic recording and reproducing apparatus includes a stator having a coil disposed on outer peripheral direction thereof, and a rotor having a magnet to correspond to coil and rotated by an electromagnetic interaction between the coil and the magnet. A capstan shaft is rotated integrally with the rotor, is fixed on the rotor and installed so that one side of the capstan shaft is cohered with a pinch roller taking a tape therebetween to drive the tape with the pinch roller. The magnet has a predetermined shape and is provided to apply magnetic force of the magnet eccentrically for an electromagnetic force generated on the coil so that a predetermined thrust can be applied to the capstan shaft toward one direction between upper and lower directions of the shaft direction.

  • Patent number: 6814271
    Abstract: The invention relates to a transmission apparatus in connection with a pulling equipment intended for moving especially a cable or a corresponding product, the transmission apparatus comprising a shaft that is operated by a motor (11) and that is connected to an output shaft (16) of the transmission apparatus by means of cog wheels (14). The output shaft (16) is connected to means (10) that are in contact with the cable. The cog wheels (14) are arranged to form a circle extending from the motor-driven shaft to the output shaft (16) and correspondingly from the output shaft (16) to the motor-driven shaft. In order to provide clearance-free operation, the cog wheels (14) are helical gearwheels, and one cog wheel shaft is arranged to be moved in its longitudinal direction when the rotation of the output shaft (16) is being decelerated.

  • Publication number: 20030226873
    Abstract: A component tape transport wheel, a component tape transport system and a method of operating a component tape transport system are provided, in which there is a rigid coupling between a transport wheel and an encoder wheel which is arranged on the transport wheel and whose position relative to a sensor can be determined. By this rigid coupling between the transport wheel which moves the component tape and a registration system including an encoder wheel and sensor for registering the position of the transport wheel, it is possible to register the position of the transport wheel at any time with the greatest accuracy. Even after a component tape transport system has been switched off, a determination of the absolute position of the transport wheel is possible, since the distance between two encoder elements of the encoder wheel is less than any play possibly caused by a drive of at least one of the transport wheel and an associated gear mechanism.
