Abstract
Abstract The invention relates to a method and apparatus for transferring objects from a first conveyor to a second conveyor which is arranged substantially perpendicularly to the first conveyor, the objects being transferred in parallel relationship to themselves. The first conveyor travels at a higher speed than the second conveyor. The transfer may be effected by means of one or more transfer members adapted to make an oblique movement in such a way that the component of velocity in the direction of travel of the first conveyor is approximately the same as the speed of the first conveyor and the component of velocity in the direction of travel of the second conveyor is approximately the same as the speed of the second conveyor.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
228 words
A method of transferring objects from an at least one belt first conveyor to at least one belt second conveyor having objects thereon spaced apart at random distances such that objects transferred to the second conveyor are spaced apart from and in a parallel relationship to each other and such that the objects do not change their relative positions in respect to other objects, comprising: (1) arranging the at least one belt first conveyor having a first coefficient of friction perpendicularly to the at least one belt second conveyor having a second coefficient of friction which is substantially less than the first coefficient of friction and such that a terminal end part of the first conveyor is next to and substantially at the same level as the second conveyor; (2) continuously moving said second conveyor at predetermined speeds and moving said first conveyor at predetermined speeds or held stationary; (3) determining the position of a first object on the first conveyor near said end part; (4) determining the position of a second object on the second conveyor near said end part; and (5) moving the first conveyor at a speed greater than the speed of the second conveyor and at a speed sufficient to move the first object onto the second conveyor at any position on the belt which is different from and parallel to the second object.
Claim 2
Independent Claim
228 words
A method of transferring objects from an at least one belt first conveyor to at least one belt second conveyor having objects thereon spaced apart at random distances such that objects transferred to the second conveyor are spaced apart from and in a parallel relationship to each other and such that the objects do not change their relative positions in respect to other objects, comprising: (1) arranging the at least one belt first conveyor having a first coefficient of friction perpendicularly to the at least one belt second conveyor having a second coefficient of friction which is substantially less than the first coefficient of friction and such that a terminal end part of the first conveyor is next to and substantially at the same level as the second conveyor; (2) continuously moving said second conveyor at predetermined speeds and moving said first conveyor at predetermined speeds or held stationary; (3) determining the position of a first object on the first conveyor near said end part; (4) determining the position of a second object on the second conveyor near said end part; and (5) moving the first conveyor at a speed greater than the speed of the second conveyor and at a speed sufficient to move the first object onto the second conveyor at any position on the belt which is different from and parallel to the second object.
Claim 3
Dependent Claim
75 words
The method of claim 1 wherein the first conveyor has a first part distant from said end part which is moved at a constant speed and a second part which is intermediate of the first part and the said terminal end part which is moved at varying speeds but at speeds lower than the speed of the first part so as to function as a buffer part between the first part and the end part.
Claim 4
Dependent Claim
36 words
The method of claim 2 wherein the end part is a third part of the first conveyor and the third part is either stationary or moved at a higher speed than the first or second parts.
Claim 5
Dependent Claim
29 words
The method of claim 3 wherein the third part is moved or held stationary as a function of the position of the said second object on the second conveyor.
Claim 6
Dependent Claim
58 words
The method of claim 2 wherein the first part is moved at a constant speed and the second part and third part are both moved simultaneously or are both stationary, and wherein the third part is moved at higher speeds than the second part and the second part is moved at a lower speed than the first part.
Claim 7
Dependent Claim
14 words
The method of claim 1 wherein there are a plurality of said first conveyors.
Claim 8
Independent Claim
247 words
An apparatus for transferring objects from an at least one belt first conveyor to an at least one belt second conveyor having objects thereon spaced apart at random distances such that objects transferred to the second conveyor are spaced apart from and in parallel relationship to each other and such that the objects do not change their relative positions in respect to other objects, comprising: (1) means for arranging the at least one belt first conveyor having a first coefficient of friction such that the first conveyor is perpendicular to the at least one belt second conveyor having a second coefficient of friction which is substantially less than the first coefficient of friction and a terminal end part of the first conveyor is next to and substantially at the same level as the second conveyor; (2) moving means for moving the said conveyors at predetermined speeds and where the second conveyor runs continuously; (3) first sensing means for sensing and determining the position of a fist object on the first conveyor approaching said end part; (4) second sensing means for sensing and determining the position of a second object on the second conveyor near said end part; and (5) control means for moving the first conveyor at a speed greater than the speed of the second conveyor and at a speed sufficient to move the first object onto the second conveyor at any position on the belt which is different from and parallel to the second object.
Claim 9
Independent Claim
247 words
An apparatus for transferring objects from an at least one belt first conveyor to an at least one belt second conveyor having objects thereon spaced apart at random distances such that objects transferred to the second conveyor are spaced apart from and in parallel relationship to each other and such that the objects do not change their relative positions in respect to other objects, comprising: (1) means for arranging the at least one belt first conveyor having a first coefficient of friction such that the first conveyor is perpendicular to the at least one belt second conveyor having a second coefficient of friction which is substantially less than the first coefficient of friction and a terminal end part of the first conveyor is next to and substantially at the same level as the second conveyor; (2) moving means for moving the said conveyors at predetermined speeds and where the second conveyor runs continuously; (3) first sensing means for sensing and determining the position of a fist object on the first conveyor approaching said end part; (4) second sensing means for sensing and determining the position of a second object on the second conveyor near said end part; and (5) control means for moving the first conveyor at a speed greater than the speed of the second conveyor and at a speed sufficient to move the first object onto the second conveyor at any position on the belt which is different from and parallel to the second object.
Claim 10
Dependent Claim
87 words

Claim 11
Dependent Claim
41 words
The apparatus of claim 8 wherein the end part is a third part of the first conveyor and the control means causes the third part to be either stationary or movable at a higher speed than the first or second parts.
Claim 12
Dependent Claim
