162 Non-contact article rotating apparatus US10578563 2004-11-10 US07665597B2 2010-02-23 Brian E. Neville
An non-contact article rotating device is disclosed that rotates articles without impacting or contacting the article other than the bottom of the article. The device is designed to accept a stream of articles with minimum gaps between them, and rotate only those that are programmed to be rotated. The device accepts any combination of rotated and non-rotated articles and can rotate them through angles up to and through 360 degrees. One embodiment of the disclosed device uses only one single-speed drive motor and pneumatic components to operate two conveyor roller sections. While one conveyor roller section maintains a constant speed, the conveyor rollers of the second conveyor roller section are sequentially braked and unbraked to rotate an article that is positioned partially on the first conveyor roller section and partially on the second conveyor roller section. The difference in speeds between the two conveyor sections rotates the article.

168 Zone control method in roller conveyor and zone controller US09821895 2001-03-30 US06459224B2 2002-10-01 Kazuo Itoh; Toshiyuki Tachibana; Yoshiyuki Kujihashi
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.
169 Method for controlling a motor roller US09725670 2000-11-29 US06456032B2 2002-09-24 Kazuo Itoh; Toshiyuki Tachibana; Shigeki Fukata
A motor driver for drive-controlling a brushless motor being provided with a delay circuit that detects the motor pulse. When a stop signal is inputted, a transistor is activated, which in turn activates an electric brake to brake the brushless motor, while at the same time, the motor pulse detected by the motor driver is inputted to the delay circuit. After the stop signal is inputted, the motor pulse declines, which is detected by the delay circuit to activate the electromagnetic brake. The delay circuit is provided on the driver substrate for the motor driver.

The bracket is adapted to elastically press the drum to the load, and has a predetermined degree of rotational movement such that the bracket may pivot about an axis transverse to the movement of the load. The bracket has an elastic device providing a first level of force and a first resistance to deformation of the bracket, and the elastic device also provides a second level of force and a second resistance to deformation of the bracket during braking of the drum, the second level of force increasing the contact force between the drum and the load. The second resistance is greater than the first resistance, and the bracket applies the second level of force up to a predetermined threshold.
173 Zoned transport conveyor with automatic zone start-up and shut-down US112618 1998-07-09 US6035999A 2000-03-14 David V. Hall
A zoned transport conveyor includes a drive roller and a series of driven rollers for each zone. A motor is interconnected with the drive roller for imparting rotation to the drive roller, which in turn is drivingly engaged with the driven rollers such as through a series of belts. Introduction of a load onto the zone results in rotation of an upstream one of the driven rollers, which is transferred through the drive arrangement to the drive roller. Rotation of the drive roller results in rotation of an output member associated with the motor, which is detected by a series of sensors associated with the motor and which provides and input to a motor control circuit. The motor control circuit includes a processor for controlling operation of the motor, and the processor functions to initiate operation of the motor when inertial rotation of the motor output member is detected. The processor functions to continue operation of the motor for a predetermined time period sufficient to allow a load to be discharged from the zone, after which operation of the motor is stopped so as to stop operation of the zone until introduction of a subsequent load. A bus spans the length of adjacent zones, and provides power supply and ground to the motor and to the control circuit. The bus may also carry a stop line providing a stop input to the control circuit, and the processor is responsive to a stop signal from the stop line so as to initiate dynamic braking of the motor to quickly stop advancement of any loads carried by the zone.
174 Wheel brake US880598 1997-06-23 US5884744A 1999-03-23 Jan S. Slodkowski
A brake for tandem wheels comprising a block that is shaped to conform to a portion of the circumferential surface of each of the wheels. The block is positioned to be in continuous frictional engagement with the circumferential surface of each of the wheels so that a constant force is applied to each of the wheels. When one of the wheels is stopped due to an external force, the mechanical forces that are built through the continuous frictional engagement result in the block exerting a braking force against the circumferential surface of the other wheel.
175 Conveyor including a braking device US602995 1996-02-16 US5642799A 1997-07-01 Jonathan Warrilow
A brake device for a conveyor has two load supporting conveyor rollers rotatable to enable a load thereon to be transported along the conveyor. The load supporting rollers are movable transversely to their axes of rotation by a load passing thereover against a resilient bias into engagement with a brake roller adapted to brake rotation of the conveyor rollers. The braking force exerted by the brake roller is dependent at least in part upon the weight of the load on the conveyor rollers.
176 Controlled flow gravity conveyor system and method US65675 1993-05-21 US5375689A 1994-12-27 Gordon K. Sapp; Mark W. Henson
A gravity conveyor system is disclosed including a device for actively stopping the rotation of the conveyor rollers following disengagement with a conveyed article after it passes thereover and in advance of a next succeeding article. This allows each article to accelerate an engaged roller from a rest position so that precise transport control is effected without the use of positive drive mechanisms. Accurate control for throughput and accumulation results from cooperation between brake assemblies associated with each conveyor roller, a sensor assembly and a pneumatic control assembly, each combination of which acts in an operational zone. The rotation of the rollers is preferably stopped as a function of the sensed position of articles along the system. The pneumatic control assembly further includes a logic control mechanism that operates to selectively control the application of braking action either momentarily to allow continued controlled throughput or for a prolonged period of time to allow controlled accumulation. The gravity control system acts to practice a method for controlling the transport of articles without positive drive assistance in reliance on stopping the rotation of the rollers after an article has passed thereover and in advance of a next succeeding article. The apparatus and method further provide a device for stopping articles at the discharge point of the conveyor system without the need for extraneous stop mechanisms.
177 Conveyor roller brake US716276 1991-06-17 US5147020A 1992-09-15 Dale Scherman; Jim Brown; Gary Carpenter
A conveyor roller brake that is preferably carried within the confines of a conveyor roller and includes a friction surface carried by the conveyor roller and a brake shoe that is maintained continuously in biased engagement with the friction surface and is selectively engageable for disengageable with respect to a nonrotatable hub element thereby selectively permitting the brake shoe to rotate freely with the conveyor roller in frictional engagement with the friction surface, or to be arrested in its rotation so that relative rotation of the roller with respect thereto provides continuous roller braking through frictional sliding of the brake shoe in biased engagement with the friction surface.
178 Constant speed decline belt conveyor US636778 1991-01-02 US5092444A 1992-03-03 Charles Agnoff
A longitudinally-extending constant speed decline belt conveyor for conveying a load along a downwardly sloped planar surface thereon. An endless traction belt rotatable about terminal rollers at the ends thereof, has an upper run extending in the longitudinal direction along the entire length of the conveyor. At least one of the terminal rollers of the endless traction belt is a speed control or braking roller for applying a braking force to the traction belt. The braking roller retards the rotation of the endless belt thereby retarding the movement of the load along the conveyor. A traction belt is utilized for braking so that the loads on the belt may have a uniform braking action applied thereto continuously as the loads move downwardly along the conveyor.
