摘要： A retarder apparatus controls the speed of a free, load-carrying conveyor as it moves in a predetermined direction along a path of travel defined by the track in which the conveyor runs. Paddle members are spaced at regular intervals along an endless movable chain and each, in turn, is positioned in the track in the path of the next conveyor. Upon engagement of an individual paddle by an oncoming conveyor, the chain is instantly accelerated to the speed of the conveyor and this motion is transmitted through a chain sprocket to a centrifugal brake which, if a normal speed is being exceeded, limits the speed of movement of the chain to hold back a runaway conveyor and return it to the normal speed.

摘要： In an indexing conveyor that employs a helically grooved drive shaft to propel a shuttle carriage that is, in turn, coupled with a product-bearing dolly, the carriage is provided with a drive connection assembly comprising a pair of follower rollers that are received within the drive shaft groove. The rollers are carried by a swivel bar on opposite sides of its axis, which is perpendicular to the axis of rotation of the drive shaft. The assembly further includes a spring that biases the swivel bar in one direction so as to maintain the followers in engagement with the leading and trailing surfaces respectively of the shaft within the groove when the shaft is at rest or rotating at constant speed. Under rapid acceleration or deceleration of the drive shaft, pivotal movement in the opposite direction against the action of the spring causes both followers to engage the trailing surface during acceleration and the leading surface during deceleration. Impact loading in the drive connection is thereby eliminated and precise positioning of the product-bearing dolly is assured.
摘要翻译：在采用螺旋槽式驱动轴的分度输送机中，推进梭式滑架，该滑架又与产品承载台车联接，托架设置有驱动连接组件，该驱动连接组件包括一对从动辊，驱动轴槽。滚子由其轴的相对侧上的旋转杆承载，该旋转杆垂直于驱动轴的旋转轴线。组件还包括弹簧，该弹簧在一个方向上偏压旋转杆，以便当轴处于静止状态或以恒定速度旋转时，分别使凹槽内的轴与凹槽内的前表面和后表面接合。在驱动轴的快速加速或减速下，克服弹簧作用的相反方向的转动使两个从动件在加速过程中与后表面接合，并在减速期间与前表面接合。从而消除了驱动连接中的冲击负载，并确保了产品承载台车的精确定位。

摘要： A high-speed, bidirectional transporter for a multiple station production line provides for the programmable pickup, transport and delivery of materials at non-sequential work stations along the production line. The transporter is self-propelled by a rack and pinion drive and moves along a track that defines a course through the multiple work stations. A turntable on the transporter carries an extensible and retractable arm whose motion, when coupled with a materialladen pallet, provides for either the pickup or delivery of a pallet to or from an individual work station. Coupling and uncoupling of the arm with a pallet is effected by the controlled rotation of the turntable, which is capable of 180 degrees of rotation to also impart to the transporter the ability to transfer pallets off of both sides to address a work station on either side of the track.

摘要： A reinforced track section for a power and free conveyor system utilizes a conventional power rail with a free trolley track suspended therefrom. A uniform rail cap is superiorly attached to the power rail so as to provide a continuous, uninterrupted reinforcement thereto. The rail cap includes a continuous mounting flange in cooperation with hanger clamps which suspend the rail cap and underlying power and free tracks from overhead support structure at user-selectable points along the flange.

摘要： A positive-acting coupling device for rigidly coupling a product-carrying dolly to the shuttle carriage of a high speed indexing conveyor is disclosed. Intercoupling of the carriage and the dolly is effected by a pair of clamp arms carried by the carriage which close against the opposed contact surfaces of a striker bar that projects from beneath the dolly. A cam mechanism on the carriage is operated by remotely mounted pneumatic cylinders located at positions along the conveyor where it is desired to either open or close the clamp arms. The cam mechanism is self-locking in the closed position of the clamp so that only a momentary actuating force applied by a cylinder is required. Since the clamp arms are closed against the opposed contact surfaces of the striker bar, no relative movement of the product-carrying dolly and the shuttle carriage is permitted.

摘要： Track sections of industrial conveyor systems are joined in end-to-end relationship using alignment devices that ensure that the internal running surfaces of the rail flanges of the track are free from irregularities at the track joints. Tubular bushings are located at the ends of the sections on adjacent external surfaces of the rail flanges out of running contact with the moving conveyor components. When the bushings are brought into register and united to form a connection, proper alignment is achieved and maintained without the need to weld the track sections together at each joint. This provides a modular track configuration to facilitate the installation and maintenance of conveyor track systems.

摘要： The invention provides an efficient and economical way for indexing products from a continuously moving chain conveyor to a stationary position for robotic operations and then returning the product to the moving chain conveyor. Indexing is achieved by a moveable shuttle carriage which is propelled along the axis of a main drive shaft through the engagement of a follower, located beneath the shuttle carriage, with a helical recess in the circumference of the shaft. Controlled acceleration, deceleration and positioning are accomplished by varying the rotational speed of a uniform helical drive shaft or by the use of a variable helical drive shaft rotated at constant speed. The shuttle carriage picks up a product carrier by engagement of a drive dog with the carrier to propel the carriage and carrier in unison to an operating station along tracks in parallelism with the axis of the shaft. Several indexing units may be employed in tandem to provide accumulation of products and to transfer each product back to the moving conveyor after the operation has been performed.
摘要翻译：本发明提供了一种有效和经济的方法，用于将产品从连续移动的链式输送机转移到用于机器人操作的静止位置，然后将产品返回到移动链式输送机。通过可移动的滑架滑架实现分度，该滑动滑架通过位于往复滑架下方的从动件与主驱动轴的轴线在轴的圆周中具有螺旋形凹槽而被推动。受控的加速，减速和定位是通过改变均匀螺旋驱动轴的转速或通过使用以恒定速度旋转的可变螺旋驱动轴来实现的。梭车通过驱动爪与载体的接合来拾取产品载体，以将滑架和载体与轴的轴线平行地沿轨道一致地推进到操作台。可以串联使用多个分度单元以提供产品的积聚并且在操作已经执行之后将每个产品转移回移动的输送机。

摘要： In a power and free conveyor system which comprises a train of free trolleys including a leading trolley and one or more following trolleys, one of the following trolleys is provided with a transfer dog that remains fully retracted within the trolley track and out of contact therewith until conveying of the train is to be transferred from a first to a second powered conveying chain. To initiate the transfer, a power dog on the first chain disengages from a drive dog on the leading trolley, and the transfer dog is raised out of the following trolley for engagement with another power dog on the first chain. Engagement of the transfer dog with the power dog is maintained preferably throughout the transfer area until the leading trolley is adjacent to the second conveyor chain for engagement of a power dog thereon with the drive dog of the leading trolley.
