Abstract
Abstract In connection with a feeding conveyor for feeding articles laterally onto a sorter conveyor is mounted a retractable V-shaped stop for the articles as conveyed on the feeding conveyor, whereby these articles are temporarily stopped and concurrently centered towards the top point of the V-stop. Hereby it is achieved that the remaining article transfer distance is well defined such that the transfer of the article to the sorter conveyor, upon retraction of the V-stop, may take place in a well defined manner. When the respective edges or sides of the V-stop are orientated parallelly with and orthogonally to the moving direction of the sorter conveyor, it is achieved, additionally, that a rectangular article as fed to the feeding conveyor with any arbitrary orientation, will be orientated so as to take up a minimum space on the sorter conveyor, whereby the capacity of the latter may kept at a maximum.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
99 words
A feeding conveyor for feeding articles laterally onto another conveyor, particularly a sorting conveyor, by a movement obliquely inwardly and forwardly towards the latter conveyor, in an intermediate area of the feeding conveyor there is arranged a generally V-shaped stop means comprising an operationally unitary structure for temporarily stopping as well as centering and lining up of articles in conjunction with the action of said feeding conveyor, said V-shaped stop means being movable towards and retractable away from its stop position as a unit for releasing the centered and lined up article for transfer thereof to the sorting conveyor.
Claim 2
Dependent Claim
99 words
A feeding conveyor for feeding articles laterally onto another conveyor, particularly a sorting conveyor, by a movement obliquely inwardly and forwardly towards the latter conveyor, in an intermediate area of the feeding conveyor there is arranged a generally V-shaped stop means comprising an operationally unitary structure for temporarily stopping as well as centering and lining up of articles in conjunction with the action of said feeding conveyor, said V-shaped stop means being movable towards and retractable away from its stop position as a unit for releasing the centered and lined up article for transfer thereof to the sorting conveyor.
Claim 3
Dependent Claim
42 words
A feeding conveyor according to claim 1, in which the V-shaped stop member is constituted by a plurality of stop pins as projecting upwardly, in a downwardly retractable manner, through the spaces between mutually spaced conveyor belts as constituting the feeding conveyor.
Claim 4
Dependent Claim
30 words
A feeding conveyor according to claim 1, in which a fixed guiding edge is provided for defining the position of the articles in the transverse direction of the feeding conveyor.
Claim 5
Dependent Claim
30 words
A feeding conveyor according to claim 1, in which the opposed sides of the V-stop are located, respectively, parallel with and orthogonal to the longitudinal direction of the sorting conveyor.
Claim 6
Independent Claim
96 words
A method for feeding articles laterally onto another conveyor comprising the steps of feeding articles on a feeder conveyor by movement obliquely inwardly and forwardly towards the another conveyor, vertically raising a V-shaped stop means in front of an article on the feeder conveyor, effecting lining up of the article abutting the V-shaped stop means in a desired orientation by action of the feeder conveyor, while the V-shaped stop means is temporarily held stationary, and vertically lowering the V-shaped stop means to allow the article to be fed onto the another conveyor in the desired orientation.
Claim 7
Independent Claim
96 words
A method for feeding articles laterally onto another conveyor comprising the steps of feeding articles on a feeder conveyor by movement obliquely inwardly and forwardly towards the another conveyor, vertically raising a V-shaped stop means in front of an article on the feeder conveyor, effecting lining up of the article abutting the V-shaped stop means in a desired orientation by action of the feeder conveyor, while the V-shaped stop means is temporarily held stationary, and vertically lowering the V-shaped stop means to allow the article to be fed onto the another conveyor in the desired orientation.
