Abstract
Abstract An alignment apparatus is disclosed for aligning weighed batches or elongated objects, such as French-Fried potato strips. The batch of objects is weighed in a scale and discharged onto a moving conveyor belt which separates the objects and projects such objects from the conveyor into a vibrated alignment container including a first container means having a curved deflector wall and a second container means with a gated discharge outlet. The objects impact a vertically-curved rear deflector wall of the first alignment container means in a direction substantially perpendicular thereto and may fall into contact with a straight front deflector wall so that they are aligned substantially parallel to such rear wall when they fall into the supply inlet of a second container means. The second container means if a rectangular tube having a gate at its discharge outlet which is normally closed. The objects are further aligned and compacted in the container tube and are discharged by opening the gate as a batch of aligned objects of small size and predetermined weight into a packaging machine which packages the weighed batch of aligned objects.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
186 words
Alignment apparatus for impact alignment of elongated objects, comprising: alignment means for aligning said elongated objects, including an alignment container means with a first container means having an inlet opening, an outlet opening, and a curved deflector wall, a second container means having a supply inlet aligned with the outlet opening of said first container means and having a discharge outlet, and gate mans for closing said discharge outlet as said second container means is being filled with elongated objects and for opening said discharge outlet to empty said second container means of said elongated objects; conveyor means for conveying elongated objects and for projecting said objects from said conveyor through the inlet opening of the first container means of the alignment container in a direction toward the curved deflector wall to cause said objects to strike said curved wall and to be deflected by the impact; and vibrator means for vibrating said alignment container means to cause a majority of the elongated objects to be aligned into a compact batch of said objects in said second container portion which is discharged from said discharge outlet.
Claim 2
Dependent Claim
186 words
Alignment apparatus for impact alignment of elongated objects, comprising: alignment means for aligning said elongated objects, including an alignment container means with a first container means having an inlet opening, an outlet opening, and a curved deflector wall, a second container means having a supply inlet aligned with the outlet opening of said first container means and having a discharge outlet, and gate mans for closing said discharge outlet as said second container means is being filled with elongated objects and for opening said discharge outlet to empty said second container means of said elongated objects; conveyor means for conveying elongated objects and for projecting said objects from said conveyor through the inlet opening of the first container means of the alignment container in a direction toward the curved deflector wall to cause said objects to strike said curved wall and to be deflected by the impact; and vibrator means for vibrating said alignment container means to cause a majority of the elongated objects to be aligned into a compact batch of said objects in said second container portion which is discharged from said discharge outlet.
Claim 3
Dependent Claim
33 words
Alignment apparatus in accordance with claim 1 which also includes feeder means for feeding said elongated objects onto a moving conveyor belt forming said conveyor means in batches of objects of predetermined amounts.
Claim 4
Dependent Claim
26 words
Alignment apparatus in accordance with claim 2 in which the feeder means includes scale means for weighing said batches before they are fed onto the conveyor.
Claim 5
Dependent Claim
36 words
Alignment apparatus in accordance with claim 3 in which feeder means feeds the batches onto the conveyor means in a manner to cause the objects of each batch to become separated and spaced along said conveyor.
Claim 6
Dependent Claim
84 words
Alignment apparatus in accordance with claim 1 in which the second container means is a rectangular tube means whose top end is coupled to the outlet opening of the first container means for receiving elongated objects from said outlet opening and causing said objects to be compacted into a batch of aligned objects in said tube means when the gate means is closed and to discharge said batch of objects from the bottom end of said tube means when said gate means is open.
Claim 7
Dependent Claim
32 words
Alignment apparatus in accordance with claim 5 which also includes packaging means for packaging the batch of aligned objects, said bottom end of said conduit discharging said objects into said packaging means.
Claim 8
Dependent Claim
38 words
Alignment apparatus in accordance with claim 1 in which the first container means has a vertically-curved deflector wall positioned above a straight deflector wall so that objects deflected by the curved wall may also strike the straight wall.
Claim 9
Dependent Claim
34 words
Alignment apparatus in accordance with claim 1 in which the curved deflector wall is curved vertically to provide a concave curved vertical surface against which the elongated objects are projected by the conveyor means.
Claim 10
Dependent Claim
28 words
Alignment apparatus in accordance with claim 1 in which the vibrator means includes a common vibrator for vibrating both said first container means and said second container means.
Claim 11
Dependent Claim
149 words
Alignment apparatus for impact alignment of elongated objects, comprising: alignment means for aligning said elongated objects, including an alignment container means with a first container means having an inlet opening, an outlet opening, and a vertically-curved deflector wall, a second container means having a supply inlet aligned with the outlet opening of said first container means and having a discharge outlet; gate means for closing said discharge outlet when said second container means is being filled with said elongated objects and for opening said discharge outlet to empty said second container means; and conveyor means for conveying elongated objects and for projecting said objects from said conveyor through the inlet opening of the alignment container in a direction which is substantially perpendicular to the curved deflector wall to cause said objects to strike said curved wall and to be deflected by the impact and discharged from said outlet opening.
Claim 12
Dependent Claim
149 words
Alignment apparatus for impact alignment of elongated objects, comprising: alignment means for aligning said elongated objects, including an alignment container means with a first container means having an inlet opening, an outlet opening, and a vertically-curved deflector wall, a second container means having a supply inlet aligned with the outlet opening of said first container means and having a discharge outlet; gate means for closing said discharge outlet when said second container means is being filled with said elongated objects and for opening said discharge outlet to empty said second container means; and conveyor means for conveying elongated objects and for projecting said objects from said conveyor through the inlet opening of the alignment container in a direction which is substantially perpendicular to the curved deflector wall to cause said objects to strike said curved wall and to be deflected by the impact and discharged from said outlet opening.
