摘要:
The present invention aims to provide a zone controller that enables construction of a conveyor line adapted for articles having various shapes and weights.The zone controller includes: an output terminal 15 for output of a driving status signal representing a driving status of the driving roller; an input terminal 16 for input of a driving status signal; and a controlling section 10 for generating a controlling signal for controlling the driving roller. The controlling section is capable of being switched between a master control mode and a slave control mode. In the master control mode, the controlling section generates the controlling signal by determining the need for driving the driving roller and outputs a driving status signal equivalent to the controlling signal via the output terminal 15, and in the slave control mode, by employing a driving status signal transmitted via the input terminal 16 as the controlling signal, the controlling section controls the driving roller synchronously with the control by the zone controller 1 from which the driving status signal is transmitted.
摘要:
A zone controller enabling flexible conveyance according to the use by simple change of setting. An aspect of the invention is a zone controller 10 for a particular zone picked from a plurality of zones for control into which a roller conveyor line 1 is divided and which are arrangeable in a row in the direction of conveyance, being capable of controlling operation of a driving roller 4a for conveyance provided in the particular zone, having a mode-setting means 14 capable of switching between a slug mode and a singulation mode. In the slug mode, operation of the driving roller is controlled so that articles in the zones are conveyed uniformly to downstream, maintaining the order of the articles in the conveying line. In the singulation mode, operation of the driving roller is controlled so that the articles are conveyed separately to downstream with a predetermined number of zones in which no article exists preserved between the zones in which the articles exist.

In a roller conveyor system for carrying out zone control, a conveyed article can be stopped in an approximately constant position without varying the position where the article is stopped in a desired control zone even if the weight of the article varies. In order to syop the article in a predetermined control zone, such stop control is carried out that a motor is decelerated and stopped in a plurality of braking systems depending on the change in the pulse width of a rotational pulse signal to stop the article with high precision in a predetermined stop position.

When a frame information (F1)C2 defining the frame type in a transmission protocol format is received in a pager, data of a following interleaving portion is received. A receiving buffer circuit converts the received data from serial data into parallel data in accordance with the frame type, and a deinterleaving circuit reproduces (deinterleaves) the converted parallel data.

A brake-controllable brushless motor has a rotor and a stator having polyphase coils; a polar position detector whereby electric power is supplied to the coil selected by its phase in response to the polar positions of the rotor detected by the polar position detector; a driver division for controlling the electric supply to the coils; a motor pulse identifier for recognizing motor pulse signals fed from the polar position detector; and a delayed pulse generator for producing phase-delayed pulse signals in response to the pulse signals fed from the motor pulse identifier, thereby ensuring that when the brushless motor is braked, the phase delay of the delayed pulse signals is progressively and continuously enlarged, and that the coils receive a controlled electric supply from the driver division in response to the delayed pulse signals.

A fault diagnosis method for a roller conveyor including rollers, brushless motors, and zone controllers for controlling the brushless motors, the brushless motors and/or the rollers each having a rotation detector, the zone controllers each having a driver containing a logic circuit, a memory, which contains a program, and a micro computer is proposed. The program includes a fault diagnosis program and a criterial parameter. The zone controllers each obtain an operating parameter of the brushless motors and/or the rollers so as to perform comparison of the operating parameter with the criterial parameter and determine a failure of the roller conveyor in a case where a result of the comparison is above a predetermined level.
摘要:
A conveyor, which has an area in its conveyor line and for adjusting intervals between articles, includes (1) a plurality of zones constituting the area and each having at least one driving motor and an article sensor, (2) a measuring means for measuring either an interval between adjacent articles in the conveying direction or a difference of time points when adjacent articles in the conveying direction pass the sensor, and (3) a motor controller for each of the zones and for varying a rotational speed of the driving motor. When the measuring means measures either the interval or the difference upon reception of signals from the sensor, the motor controller either accelerates or slows down the rotational speed of the driving motor in a zone where the article is placed.

In manufacturing the iron core of a divided stator, a plurality of pole pieces with fitting portions formed on both sides of pole portions are laminated and fixed to one another. A plurality of the pole piece laminates are arranged in the form of a ring and the outer or inner circumference is held with a jig. A non-magnetic and high-rigidity connecting member is press-fit in the laminating direction into fitting portions of a plurality of adjacent pole piece laminates, thereby a plurality of adjacent pole piece laminates are positioned with high accuracy and rigidly connected to one another.
