Abstract
Abstract Apparatus for depositing articles in rows on a tray, conveyor, or the like. The apparatus employs a conveyor belt which receives the articles at one end of its transport length and drops them from the other. A plurality of guides are provided for guiding the belt; these guides include a stationary guide defining one end of the transport length of the belt and a movable guide defining the other. The movable guide is movable in a linear direction above the receiving tray or conveyor to vary the transport length of the belt. According to the invention, the conveyor belt is advanced a prescribed distance from the stationary to the movable guide by a first drive means each time an article is received by the belt, and the movable guide is moved in the linear direction by a second drive means each time a prescribed number of articles have been received. The second drive means is separate from, but operates in dependence upon the first drive means to move the movable guide in the direction opposite to the direction of movement of the conveyor belt and back again in one swift action.

Claim 1
Independent Claim
194 words
Apparatus for depositing articles in rows on a receiving member comprising, in combination: a. a conveyor belt; b. a plurality of guide means for guiding said conveyor belt, said guide means including a first stationary guide means defining one end of the transport length of said belt and a first movable guide means defining the other end of the transport length of the belt, said movable guide means being movable in a linear direction over the receiving member, thereby to impart to said conveyor belt a variable transport length; c. first means, including a first electric motor, for intermittently advancing said conveyor belt from said first stationary guide means to said first movable guide means when each article is received by said belt at said one end; and d. second means, including a second electric motor, for moving said first movable guide means in said linear direction in synchronism with the movement of said first means, said second means, after a prescribed number of articles have been received at said one end, moving said first movable guide means in the direction Opposite to the direction of movement of said conveyor belt and back again.

Apparatus for depositing articles in rows on a receiving member comprising, in combination: a. a conveyor belt; b. a plurality of guide means for guiding said conveyor belt, said guide means including a first stationary guide means defining one end of the transport length of said belt and a first movable guide means defining the other end of the transport length of the belt, said movable guide means being movable in a linear direction over the receiving member, thereby to impart to said conveyor belt a variable transport length; c. first means, including a first electric motor, for intermittently advancing said conveyor belt from said first stationary guide means to said first movable guide means when each article is received by said belt at said one end; and d. second means, including a second electric motor, for moving said first movable guide means in said linear direction in synchronism with the movement of said first means, said second means, after a prescribed number of articles have been received at said one end, moving said first movable guide means in the direction Opposite to the direction of movement of said conveyor belt and back again.
Claim 3
Dependent Claim
35 words
The apparatus defined in claim 1 wherein said conveyor belt is an endless belt and surrounds said first stationary and said first movable guide means, and wherein said first stationary guide means includes a roller.
Claim 4
Dependent Claim
25 words
The apparatus defined in claim 1 wherein said second means includes a sliding carriage, said first movable guide means being mounted on said sliding carriage.
Claim 5
Dependent Claim
91 words
The apparatus defined in claim 3 wherein said first stationary guide means includes a first stationary roller and means for preventing said first stationary roller from rotating in the direction opposite to the transport direction of said conveyor belt, and wherein said plurality of guide means further includes a second and third stationary roller and a second movable guide means mounted on said sliding carriage, said second movable guide means being a roller, thereby to maintain tension in said conveyor belt when said first and second movable guide means are moved.
Claim 6
Dependent Claim
73 words
The apparatus defined in claim 1 wherein said first means includes means connecting said first electric motor to rotate said roller forming said first stationary guide means; means for sensing the receipt of each article by said belt at said one end and switching on said first electric motor in response thereto; and means for switching off said first electric motor after said first electric motor has moved said belt a prescribed distance.
Claim 7
Dependent Claim
53 words
The apparatus defined in claim 5 wherein said means for switching off said first electric motor includes a rotatable control shaft means mechanically coupled to be rotated by said first electric motor, and means for switching off said first electric motor upon rotation of said control shaft means a prescribed first angular distance.
Claim 8
Dependent Claim
37 words
The apparatus defined in claim 6, wherein said means for switching off said first electric motor includes means for switching on said second electric motor upon rotation of said control shaft means a prescribed second angular distance.
Claim 9
Dependent Claim
76 words
The apparatus defined in claim 7, wherein said second angular distance of said means for switching on said second electric motor is a multiple of said first angular distance of said means for switching off said first electric motor, said multiple being the number of articles which are deposited on the receiving member when said first movable guide means are moved in the direction opposite to the direction of movement of said belt and back again.
Claim 10
Dependent Claim
23 words
The apparatus defined in claim 6, wherein said first angular distance of said means for switching off said first electric motor is adjustable.
Claim 11
Dependent Claim
23 words
The apparatus defined in claim 7 wherein said second angular distance of said means for switching on said second electric motor is adjustable.
Claim 12
Dependent Claim
67 words
The apparatus defined in claim 3, wherein said second means further includes an electric motor; crank means, mechanically coupled to be rotated by said electric motor; and drive means, connecting said sliding carriage with said crank means, for moving said first movable guide means in the direction opposite to the direction of movement of said conveyor belt and back again during one revolution of said crank means.
Claim 13
Dependent Claim
27 words
The apparatus defined in claim 11 wherein said second means further includes means for switching off said electric motor after a complete revolution of said crank means.
