Abstract

A peanut applicator has a rotating cylindrical member with air passages therein. A vacuum pump draws air from an interior portion of the cylindrical member, air being drawn in through a plurality of air passages located between an inner surface of the cylindrical member and an outer surface having a groove therein.

The groove has a generally semi-circular cross sectional shape.

An extrudate rope passing beneath the cylindrical member in proximity to the groove will cause adhesion to articles which were retained by the vacuum of the air passageways in the groove.

Upstanding walls are disposed in a fixed plate, the plate having an aperture therethrough communicating with the interior of the cylindrical member, the cylindrical member being generally cup-shaped.

The stationary member has two air passages therethrough for introduction of air into communicating air passageways in each of the upstanding walls;

whereby introduction of air into the upstanding walls assists removal by applying air pressure to individual peanuts through said air passages so they will adhere to the extrudate rope.

Claims

1. An apparatus for applying discrete articles, such as peanuts, raisins or the like, to an outer surface of a moving continuous rope of a comestible material, comprising:

(a) a hollow rotatable cylinder having a horizontal axis, an inner surface and an outer surface, wherein said outer surface is provided with a groove, said groove being adapted to closely abut surfaces of the continuously moving rope;

(b) air passages extending from the inner surface of the cylinder to the outer surface within the groove;

(c) means for rotating the cylinder;

(d) means for applying vacuum to the inner surface of the cylinder to retain the articles on the air passages within the groove as the cylinder passes by a hopper for supplying the articles to the cylinder;

(e) means for interrupting the vacuum on the articles as the cylinder delivers the discrete articles to the rope of comestible material.

2. The apparatus of claim 1 wherein the groove conforms in cross-section to the rope.

3. The apparatus of claim 2 wherein the groove is annularly recessed on an outer circumference of the cylinder.

4. The apparatus of claim 3 wherein the air passages located in the groove are situated on side and central areas to apply the discrete articles to sides and central areas of the rope.

5. The apparatus of claim 4 where the means for interrupting the vacuum on said discrete articles comprises a radially extending stationary wall inside the cylinder having an end adjacent the inner surface, said stationary wall comprising an air inlet passageway for conducting air to the end of the stationary wall adjacent the inner surface.

6. The apparatus of claim 5 where the end of the stationary wall adjacent the inner surface comprises an air supply slot for communicating with the air passageway extending from the inner surface of the cylinder to the outer surface within the groove.

7. The apparatus fo claim 6 where the means for interrupting the vacuum on said discrete articles comprises two radially extending stationary walls inside the cylinder having an end adjacent the inner surface, wherein each stationary wall is provided with an air inlet passageway and an air supply slot.

8. The apparatus of claim 6 wherein the rotatable cylinder comprises a stationary drum end member for rotatably supporting the cylinder, wherein the stationary wall is mounted on the stationary drum end member.

9. The apparatus of claim 8 where the stationary drum end member comprises an air inlet communicating with the air inlet passageway and the air supply slot, whereby air conducted through the air inlet, air inlet passageway, air supply slot and air passages interrupts vacuum in the air passages leading to the outside surfaces of the cylinder causing retained discrete articles to drop onto the continously moving rope.

10. The apparatus of claim 9 wherein the stationary drum end member is disc-shaped with an aperture therethrough adapted to receive an axle.

11. The apparatus of claim 3 where the cylinder further comprises a plurality of grooves for accommodating a plurality of moving, continuous ropes.

12. The apparatus of claim 10 where the cylinder further comprises a rotatable drum end member which is rotatable with the cylinder, said rotatable drum end member having an aperture therethrough to receive an axle.

13. The apparatus of claim 12 where the means for rotating the cylinder comprises an axle rod having first and second ends, wherein said rod extends through the cylinder, the stationary drum end member and the rotatable drum end member.

14. The apparatus of claim 13 further comprising a first stationary end plate adjacent an outside surface of the stationary drum end member, a second stationary end plate adjacent an outside surface of the rotatable drum end member, said first and second stationary end plates being provided with apertures for receiving the ends of the rod.

15. The apparatus of claim 14 wherein the rotatable drum end member is fixedly connected to the cylinder and fixedly connected to the rod, whereby rotation of the rod rotates the cylinder.

16. The apparatus of claim 15 wherein the end of the rod received in the second stationary end plate projects from the aperture in the plate and is connected to an electric motor for rotating the rod.

17. The apparatus of claim 16 further comprising a front wall plate and a back wall plate for connecting the stationary end plates and providing an enclosure for the cylinder.

18. The apparatus of claim 17 wherein the back wall plate is shorter than the front wall plate leaving a portion of the cylinder groove exposed.

19. The apparatus of claim 18 further comprising a hopper connected to the back wall plate with the exposed portion of the cylinder groove in communication with the contents of the hopper.

20. The apparatus of claim 19 where the first stationary endplate comprises an air hose inlet communicating with the air inlet passageway for conducting air to the end of the stationary wall adjacent the inner surface and a vacuum outlet bore communicating with the inside of the cylinder.
