A conveying arm of the invention includes a first pivotable shaft connected to a first arm which is also pivotably connected to a third arm having an intermediate pivotable portion. The third arm is also pivotably connected to a fifth arm which is also pivotably connected to a seventh arm which has a holding portion for an object to be conveyed. The conveying arm also includes a second pivotable shaft connected to a second arm which is also pivotably connected to a fourth arm having an intermedi...

A conveying apparatus suitable for driving a number of carriers in such a manner that the front end of each carrier thrusts the rear end of the preceding carrier is provided. The conveying apparatus comprises a guide rail and carriers. The rail includes a U-turn path section. Each carrier includes a load bar assembly including at least three load bars connected end-to-end by vertical pivot shafts in such a manner that the bars can pivot horizontally relative to each other. Each carrier also incl...

A conveying apparatus (1) is composed of several conveying modules (2) each having a controller (40) for control of a motorized roller (6) having a motor (16) incorporated in it. A motor-controlling section (45) installed in the controller (40) operates to sense an article being transported on and along the module (2). An article-state detector (48) included in the motor-controlling section (45) compares the actual number (Pr) of signal pulses indicating the number of rotations of the motor (16)...

A conveying device in which a conveying arm assembly can be quickly set in a conveying position and can be rapidly stabilized in the conveying position includes a conveying arm assembly, a fixed shaft, at least one set of hollow operating shafts which are necessary for controlling an operation of the conveying arm assembly, and a motor provided between the fixed shaft and each of the operating shafts. The one set of operating shafts are attached to the fixed shaft such that they can be rotated c...

Apparatus for conveying metal articles between work stations comprises spaced apart skids which have substantially continuous conveying surfaces composed of rows of rotatable elements. The elements have their rotational axes inclined at a small angle which is in the range 2-10 degrees away from the normal to the conveying surface and have work surfaces which are rotatable so that portions thereof move into and out of the conveying surface.

A conveying system is provided for moving a pallet along straight and curved paths. The conveying system includes a track on which the pallet is mounted for movement by a motor driven roller which engages a stationary shaft mounted on the track. The drive roller is urged into contact with the shaft and is capable of clockwise and counterclockwise rotation in order to effectuate forward or reverse motion of the pallet. A control device is provided for controlling the speed and stopping and starti...

The present invention concerns a conveying device with an endless conveyor belt, which has catches extending essentially transverse to the conveying direction. In order to further develop a previously known conveying device so that small bulk articles, which tend to stick, are reliably removed from the conveying device at an end point of the conveying device, which cannot be reached satisfactorily with the known devices for stripping, it is proposed that the catches be deepened trough-like or el...

A conveying apparatus. The apparatus includes an air-cooled hydraulic driving unit, a hydraulic motor, a conveyor and a connecting element. The air-cooled hydraulic driving unit includes a hydraulic pump, an electrical motor, pipes, a flow regulator, and a cooling fan. The cooling fan is adapted for low temperature environment and does not require complicated pipes, so that the conveying apparatus of the present invention can be flexibly combined with other devices or applied to various processe...
