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 processing apparatus for processing a flexible substrate, particularly a vacuum processing apparatus for processing a flexible substrate, is described. The processing apparatus includes a vacuum chamber; a processing drum within the vacuum chamber, wherein the processing drum is configured to rotate around an axis extending in a first direction; and a heating device adjacent to the processing drum, wherein the heating device is configured for spreading the substrate in the first direction or for maintaining a spread of the substrate in the first direction, and wherein the heating device has a dimension in a direction parallel to a substrate transport direction of at least 20 mm.
Abstract:
There are provided two flat belts which rotate in opposite directions. Between the two belts, materials are put and conveyed upwards. A head pulley around which one of the belts is wound is driven by a motor, and another head pulley around which the other of the belts is wound is connected to the head pulley driven by the motor via sprockets, an endless chain, a shaft and two gears. The two belts are driven and rotated by the same motor, thereby simplifying its structure.
Abstract:
The chain drive described in the present disclosure, instead of using a single sprocket wheel, saves space by making use of two or more sprocket wheels coupled together by slip-free means, each sprocket wheel having only a small number of low sprockets. The number of sprocket wheels, the center-to-center distance between the sprocket wheels, the tip diameter of the sprocket wheels, and the phase offset of the sprockets as between the sprocket wheels which form a set of such wheels are all so matched that one sprocket of one sprocket wheel always engages in the chain in rhythmical sequence, so that all the sprocket wheels rotate smoothly when the chain moves evenly.
Abstract:
A belt conveyor for packaging apparatus includes an endless belt which supports a plurality of spaced article receiving cells, the belt being passed about a pair of direction-changing wheels. Variations in the loading of the endless belt are minimized by coupling the drive shaft, by which power is delivered to a first of the wheels, to a drive shaft for the other wheel via at least one rotationally fixed cardan connection.
Abstract:
A helical conveyor system is disclosed. A conveyor belt 11 is positively driven by drive cage 212 around a plurality of vertically spaced helical loops. A pair of supplemental positive drives 25 and 26, which are driven at the same speed and synchronized with the drive cage, engage the belt 11 near its entry into and exit from the helical portion of its endless path. Vertical driving bars 45 on the drive cage 21 positively engage the cross rod heads 14 of the belt 11 in its helical path. The driving surfaces of the bars 45 are relieved at 61 and 62 to prevent driving engagement with the rod heads 14 over an inlet section of the first loop and an exit section of the last loop. The driving bars 45 also engage the ends of the rod heads 14 to limit the penetration of the driving bars past the edge of the belt. The driving bars include means which may comprise gates 105 or ramps 121 to permit controlled intermittent slip-backs of the rod heads at predetermined intervals.
Abstract:
A belt-type conveyor having an endless belt supported on a pair of spaced end rollers. The upper reach of the belt is adapted to have articles supported thereon for transporting thereof. A drive system is interconnected to both end rollers to simultaneously rotatably drive same, which end rollers in turn drive the belt. This drive system permits the upper reach of the belt to be maintained relatively free of tension so that the upper reach will readily conform to a guide structure which is positioned thereunder for slidably supporting same. The conveyor is particularly suitable for use as an inclined conveyor to permit lifting of articles on the upper belt reach, which upper reach can be bent upwardly from a horizontal position without requiring top guide rails or other hold-down devices.
