IPC: B65G47/51
Filed: 1983-03-30
Abstract: EP--91856 A Solid objects are transferred from a conveyor (1) which runs at a steady speed to a conveyor (5) which runs faster but is repeatedly stationary for brief intervals. The objects are transferred to a second conveyor (3) running at the same speed and in the same direction as the first conveyor. - A platform (6) rotating about a vertical axis which also oscillates in the line of the conveyor transfers the objects to a third conveyor (4) which runs at the same speed and in the same direction as the intermittently moving conveyor (5). The peripheral speed of the rotating platform is equal to the mean of the speeds of the steady and intermittent conveyors.

(12pp Dwg.No.1/6) - EP--91856 B Process for regulating the transfer, without any change in spacing or in position, of solid products or articles of identical shapes and sizes delivered continuously from an upstream machine towards a downstream receiving machine faster, but subject to brief stops, according to which process, on the one hand, a first endless linear conveyor (3) arranged horizontally is driven in the same direction and at the same speed as the so-called entry conveyor (1) connecting the upstream machine to a device and, on the other hand, a second endless linear conveyor (4) arranged horizontally parallel to the first is driven in the same direction and at the same speed as the so-called exit conveyor (5) connecting the device to the downstream machine, the two conveyors equipping the device thus driven in opposite translational movements, being placed in communication with one another by means of an intermediate conveyor (6,8), the latter being driven in an advancing movement and a translational movement parallel to the two linear conveyors (3 and 4), in such a way that the translational speed of the intermediate conveyor is equal to half the difference between the entry and exit speeds, whilst the advancing speed of the intermediate conveyor is such that its circumferential speed is equal to half the sum of the entry and exit speeds, this process also being characterised in that: - the first and second endless linear conveyors (3,4) are arranged in the same horizontal plane, the intermediate conveyor being a circular platform (6) or an endless conveyor of semi-circular path (8).  (7pp) GBAB- GB2118125 B An apparatus for transferring solid products or articles of identical size and shape without changing their position or spacing, wherein the products or articles are discharged from an upstream machine at a constant speed for a downstream machine having a higher rated speed with short dwells, said apparatus comprising a first linear endless conveyor arranged horizontally and driven in the same direction and at the same speed as an inlet conveyor fed by the upstream machine, and a second linear endless  conveyor arranged horizontally, and parallel to and in substantially the same plane as the first conveyor, the second conveyor being driven in the same direction and at the same speed as an outlet conveyor feeding the downstream machine, the first and second conveyors being driven for translation in opposite directions, interchange means having a substantially horizontal conveying plane for bringing the first and second conveyors into communication with each other, the conveying plane of  the interchange means lying close to the plane of the first and second conveyors, the first and second conveyors extending substantially tangentially to the interchange means, the interchange means having an axis of rotation extending perpendicular to the plane, the interchange means being mounted for translatory movement parallel to the first and second conveyors, the translatory speed of the interchange means being equal to one-half the difference between the displacement speeds of the first and second conveyors, the rotational speed of the interchange means being such that the tangential speed of the interchange means is equal to one-half the sum of the displacement speeds of the first and second conveyors.a - GB2118125 B An apparatus for transferring solid products or articles of identical size and shape without changing their position or spacing, wherein the products or articles are discharged from an upstream machine at a constant speed for a downstream machine having a higher rated speed with short dwells, said apparatus comprising a first linear endless conveyor arranged horizontally and driven in the same direction and at the same speed as an inlet conveyor fed by the upstream machine, and a second linear endless conveyor arranged horizontally, and parallel to and in substantially the same plane as the first conveyor, the second conveyor being driven in the same direction and at the same speed as an outlet conveyor feeding the downstream machine, the first and second conveyors being driven for translation in opposite directions, interchange means having a substantially horizontal conveying plane for bringing the first and second conveyors into communication with each other, the conveying plane of the interchange means lying close to the plane of the first and second conveyors, the first and second conveyors extending substantially tangentially to the interchange means, the interchange means having an axis of rotation extending perpendicular to the plane, the interchange means being mounted for translatory movement parallel to the first and second conveyors, the translatory speed of the interchange means being equal to one-half the difference between the displacement speeds of the first and second conveyors, the rotational speed of the interchange means being such that the tangential speed of the interchange means is equal to one-half the sum of the displacement speeds of the first and second conveyors. USAB- US4549647 A The feed is for transferring biscuits, without changing their position or spacing, between an upstream machine discharging the articles at a constant speed to a downstream machine having a higher rated speed with short dwells. The articles are fed from the upstream machine to a first linear conveyor. A second, parallel linear conveyor feeds the articles in the opposite direction towards the downstream machine. - A circular turntable or semicircular conveyor has a semicircular path of movement between the first and second conveyors for transferring the articles between them. The turntable or  semicircular conveyor is mounted for translation on a carriage parallel to the first and second conveyors. (4pp)g
