Abstract:
In the prior art, in transport lines equipped with multiple stages of transport lines driven in different directions, it was necessary that drive power sources for driving the belts of the transport lines be provided in a number equal to the number of transport lines. This led to an increased number of drive power sources and to an unavoidable increase in the power consumed by the device as a whole. In the present invention, there is adopted a mechanism for the parallel driving of a plurality of transport lines by a single drive power source, whereby the number of drive power sources needed to drive the transport lines can be reduced, as can the power consumed by the system.
Abstract:
A solar cell module conveyer comprising an assembly line for intermittently feeding solar cells that constitute a solar cell module, and having machinery arranged for successively executing the working/treating steps; belt conveyers working as an inspection line which is synchronized with the assembly line to inspect the solar cell module fabricated on the assembly line through various working/treatment steps; and a transfer mechanism for transferring the solar cell module from the assembly line onto the belt conveyers.
Abstract:
In a drive system for a mail processing machine a comparatively simple and clear design of the driving tracks and of the bearings for the respective shafts is obtained by feeding drive energy from a common drive motor to a bevel gear drive and a step gear drive. Thereby, the output shafts of the bevel gear drive and the step gear drive have identical sense of rotation because of the sense of rotation reversal within the respective gear drive. The bevel gear drive, at its output, provides a continuous rotation, and the step gear drive provides an intermittent rotation. From the output shafts of the bevel gear drive and of the step gear drive, respectively, driving connections can be led to the driving shafts for a continuously moved conveyor chain for documents and to an intermittently moved conveyor chain for documents, respectively.
Abstract:
A plurality of transport lines having driving belts are driven to transport specimen racks on which a specimen container is disposed. A single driving motor having a rotating shaft, a shaft for transmitting power of the driving motor, drives the driving belt and a plurality of pulleys transmit rotation of the shaft to the belts to drive the belts.
Abstract:
An adjustable chain drive system is adapted for uses such as moving product through a conveyor system, and can be configured using a chain, belt or similar structure. Two driven sprockets are movable on a slide, allowing the distance between them to be adjusted. In one example, such adjustment allows conveyor belts to be separated by a desired distance. A drive sprocket and endless chain is used in the drive system. In one configuration, the endless chain includes an adjustable chain segment separating the first and second driven sprockets. To compensate for movement of the first and/or second driven sprockets and change in length of the adjustable chain segment between them, lengths of first and/or second secondary adjustable chain segments adjacent to the adjustable chain segment are varied.
Abstract:
A conveyor for conveying products comprises at least two drivable endless conveyor members for supporting products. The conveyor members extend substantially parallel to each other as seen from above and define a helical path. The conveyor is arranged such that under operating conditions the conveyor members have substantially equal angular speeds.
Abstract:
A drive apparatus for a mail-processing system is specified, which apparatus has an enclosure-collating path, which is intermittently driven at least in one end section, an adjoining inserting station for sets of enclosures and an envelope-filling table, which extends parallel to the enclosure-collating path and in front of the inserting station and over which envelopes pulled from a stack of envelopes are pulled by means of an envelope-gripper chain in front of the inserting station and held open there and, once filled with the sets of enclosures, are conveyed away by the gripper chain. A reduction of mass moments of inertia of the drive for the envelope-gripper chain together with simplification of the structure of this drive and a conveying system of a modular design are achieved by a drive section as a chain drive or toothed-belt drive being guided downwards from an intermittently rotating drive shaft out of the region of the enclosure-collating path to a chain wheel or a belt pulley which is mounted in a substructure of the envelope-filling table. From there, a chain drive or toothed-belt drive leads in the substructure of the envelope-filling table to a chain wheel or a toothed-belt pulley which is mounted at the free end of a rocker, the free end of the rocker undergoing an approximately vertically oriented guidance in the substructure of the installation, while the upper end of the rocker is supported and mounted coaxially in relation to a drive shaft for the envelope-gripper chain on the envelope-filling table which is displaceable in relation to the substructure. A chain drive transmits the intermittent drive movement finally from the lower end of the rocker to the upper end of the rocker, onto the drive shaft which is coaxial to the rocker pivoting axis and is intended for the driving-chain wheel of the envelope-gripper chain.
Abstract:
A conveyor drive mechanism has a continuous drive loop trained over first, second, and third pulleys, with the first and second pulleys disposed in driving relationship to a support bed or conveyor, and a driving facility which supplies drive torque in either direction to the third pulley, to move the drive loop and conveyor in the selected direction. Counterpoised anti-backlash motors impart equal, opposed counter-torques to the first and second pulleys to impose a predetermined level of continuous tension in the active area of the drive loop, even during reversal of the direction of the torque transmitted by the driving facility.
