Abstract
Abstract A vibrating conveyor has a working mass drivable in vibrations, a counter mass which is also driven via the working mass in vibrations which are transferred to a support or a mounting base, and a device for dampening or reducing this transmission which includes a plurality of roller bearing elements provided between the vibrating conveyor and a mounting base and each formed as a unit including two bearing shells with running tracks and at least one roller part between the running tracks, wherein the running tracks before and after the roller part is inclined in opposite direction in form of a predetermined curve, and when the counter mass is driven in rotation the counter mass and the mounting base are pressed from one another by the roller bearing element which results in damping relative to the mounting base.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A vibrating conveyor, comprising a working mass driveable in vibrations in a predetermined direction and having a conveying surface for supporting a workpiece to be conveyed over a conveying path; drive means arranged to drive said working mass in vibrations for vibrating said working mass and said counter mass at least in a horizontal direction; a counter mass serving as a base body; a support surface on which said counter is mounted; connecting means for connecting said working mass with said colunter mass; and means provided between said counter mass and said support surface for vibration isolation and/or damping of horizontal vibratory forces, said means for vibration isolation and/or damping including a plurality of horizontally spaced units each having two oppositely facing vertically spaced bearing surfaces and a roller element positioned to freely rotate therebetween, said bearing surfaces each being formed symmetrically about a vertical plane which extends perpendicular to the conveying path, at least one of said bearing surfaces being concave.
Claim 2
Dependent Claim
162 words
A vibrating conveyor, comprising a working mass driveable in vibrations in a predetermined direction and having a conveying surface for supporting a workpiece to be conveyed over a conveying path; drive means arranged to drive said working mass in vibrations for vibrating said working mass and said counter mass at least in a horizontal direction; a counter mass serving as a base body; a support surface on which said counter is mounted; connecting means for connecting said working mass with said colunter mass; and means provided between said counter mass and said support surface for vibration isolation and/or damping of horizontal vibratory forces, said means for vibration isolation and/or damping including a plurality of horizontally spaced units each having two oppositely facing vertically spaced bearing surfaces and a roller element positioned to freely rotate therebetween, said bearing surfaces each being formed symmetrically about a vertical plane which extends perpendicular to the conveying path, at least one of said bearing surfaces being concave.
Claim 3
Dependent Claim
29 words
A vibrating conveyor as defined in claim 1, wherein said at least one bearing surface has two portions which are united with one another in form of a curve.
Claim 4
Dependent Claim
61 words
A vibrating conveyor as defined in claim 2, wherein each of said units is provided with two further such oppositely facing vertically spaced bearing surfaces with at least one of said further bearing surfaces being concave, each of said units being formed with an increasing raised formation provided between said one concave bearing surface and said one further concave bearing surface.
Claim 5
Dependent Claim
35 words
A a vibrating conveyor as defined in claim 1, wherein said bearing surfaces and said roller elements form first and second members, respectively, at least one of said members being composed of an elastic material.
Claim 6
Dependent Claim
18 words
A vibrating conveyor as defined in claim 4, wherein all said members are composed of an elastic material.
Claim 7
Dependent Claim
26 words
A vibrating conveyor as defined in claim 4, wherein said elastic material is selected from the group consisting of a rubber and a synthetic plastic material.
Claim 8
Dependent Claim
44 words
A vibrating conveyor as defined in claim 1, wherein said working mass is rotatable relative to said surface about an axis so as to form a rotatable vibrating conveyor, said roller element being formed as a conical roller extending in a substantially radial direction.
