Conveyor apparatus for electronic waste transfer

Abstract

A shielded conveyor apparatus for use with a shredder machine to transfer shredded material. The conveyor apparatus includes a base supporting an inclined ramp with a bottom inlet and a top discharge. A conveyor belt, driven by a motor positioned adjacent the top discharge, is shielded along its length by a cover and viewable through sight glasses. The belt is formed with opposed side walls and spaced barrier walls extending from its surface to define material-carrying pockets that control the quantity of material transported while preventing spillage during rotation. The conveyor couples to a shredder machine housing one or more sets of shredder teeth driven by motors to process objects of varying sizes, including hard drives, solid state drives, CDs, and USB cards. Shredded material exits the shredder through a chute and enters the conveyor inlet for controlled transfer to a discharge or collection bin.

3. The shielded conveyor apparatus of claim 1, wherein the cover is constructed of sheet metal.

4. The shielded conveyor apparatus of claim 1, wherein the cover is constructed of plastic.

5. The shielded conveyor apparatus of claim 1, wherein the opposing side walls of the conveyor belt cooperate with the divider walls to prevent shredded material from spilling off the conveyor belt during rotation.

6. The shielded conveyor apparatus of claim 1, wherein the divider walls are positioned at a predetermined distance along the conveyor belt to control the amount of shredded material transferred by each pocket.

7. The shielded conveyor apparatus of claim 1, wherein the divider walls are selected from the flexible material group consisting of: polyurethane, PVC, natural rubber, neoprene, nitrile, EPDM, silicone, or thermoplastic elastomers.

DETAILED DESCRIPTION OF THE INVENTION

(11) While the present invention is susceptible to embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred, albeit not limiting, embodiment with the understanding that the present disclosure is to be considered an exemplification of the present invention and is not intended to limit the invention to the specific embodiments illustrated.

(12) Referring to FIGS. 1A-1C, illustrated is the shielded conveyor apparatus 10 having a base 12 supporting an inclined ramp 14 having a bottom inlet 16 and top discharge 18. A motor 20 is positioned adjacent to the top discharge 18 for rotation of a conveyor belt 25 which can be viewed through sight glass 22 and 24. The conveyor belt 25 is accessible through the bottom inlet 16 which is placed beneath a discharge port. A shield 15 is used to cover the conveyor belt extending from a lower cover 26 to an upper cover 27 placed over the top discharge 18 using interim shields 29 and 31. The lower cover 26 includes an inlet 16 positionable beneath a shredder discharge of a shredder machine. The shields are constructed from sheet metal or plastic.

(13) The conveyor belt 25 is further defined as a base 31 forming a continuous length with divider walls 33 spaced apart along the length thereof preferably constructed of a flexible material having high tensile strength, load-bearing, and good flex/fatigue life. A first side wall 35 and a second side wall are formed integral with said base 31 employing corrugations allowing the side walls to compress during inward turns and expand during outward turns. The base 31, divider walls 33 and side walls 35, 37 form continuous pockets to move material without loss. The side walls 35, 37 maintain their height during movement which inhibits material from falling over the side walls during rotation of the belt 25. Materials suitable for conveyor belt construction can be selected from the group consisting of: Polyurethane; PVC (vinyl); Natural Rubber, Neoprene, Nitrile, EPDM, Silicone, or Thermoplastic Elastomers.

(14) FIG. 2 depicts a shredder machine 100 having a housing 102 that conceals the rotating shredders. The shredder machine 100 may be mounted on wheels 104 with a bin access area 106 that can be used for housing of a transfer bin, not shown, or the bottom inlet 16 of the conveyor apparatus 10.

(15) FIG. 3 illustrates the shredder machine 100 having drive motors 110, 112 coupled to a drive shaft 114 for rotation of shredder teeth 116 for larger objects such as hard disk or solid state drives, and shredder teeth 118 for smaller objects such as CD's, USB cards, and the like. The conveyor apparatus 10 having the bottom inlet 16. Shredded material drops from the large shredder teeth 116 and small shredder teeth 118 through the guide shoot 122. The conveyor belt 25 formed from a flexible material having first continuous side wall 30 spaced apart from a second continuous side wall 32. A plurality of barrier walls 34 protrudes from the surface 36 of the belt 25 at a predetermined distance. As the belt 25 rotates, the first and second wall 30 & 32 cooperated with a first and second barrier wall 34 forming pockets to facilitate transfer of material, wherein each pocket is limited in how much material can be carried. The side walls 30, 32 prevents shredded material from falling off the belt during rotation.

(16) FIG. 4 illustrates a side view of the conveyor apparatus 10 having a base 12 supporting an inclined ramp 14 with a top discharge 18. The motor 20 is positioned adjacent to the top discharge 18 for rotation of a conveyor belt 25 with an idler roller 40 to keep the conveyor belt 25 along the inclined ramp 14. The shredder machine 100 having a housing 102 that conceals the shredders. The shredder machine 100 can be serviced from the back side 110 with a bin access area 106 for receipt of the bottom inlet of the conveyor apparatus 10.

(17) FIG. 5 further illustrates the shredder teeth 116 with the shoot 122 leading to the intake 16. The idle roller 40 operates in conjunction with the return roller to keep the belt horizontal wherein the pockets 27 are formed for receipt of the maximum amount of material from the shoot 122.

(18) FIGS. 6A and 6B illustrate the conveyor belt 25 covered with a lower shield 26, mid shields 29, 31, and upper shield 27. The conveyor belt is illustrated with a continuous base 31 having divider walls spaced along its surface to segment the flow. The base 31 is constructed of a flexible material with each side wall incorporating corrugations that allow the side walls to compress during inward turns such at that provided by rollers 41, 43 and outward turns depicted by an end roller 45. The base, divider walls, and side walls define continuous pockets that receive shredded material and transport it without loss. The side walls maintain their height throughout belt movement, preventing shredded material from spilling over the edges during rotation of the belt.

(19) FIG. 7 is a pictorial illustrating the shredder machine 100 coupled to the shield conveyor assembly 10 for delivery of waste to a transfer bin 150. A flexible shield 12 can be placed around the discharge end 18 so as to collect all debris into the bin 150 and reduce airborne dust.
