Embodiment Construction

[0018] Referring now to the accompanying drawings, which are only used to describe preferred embodiments of the present invention and are not intended to limit the present invention, figure 1 Shown is a bumper 10 having a trunk portion 12 of width W1 and a fixed portion 14 of width W2, constructed of the same material, preferably polyurethane. The trunk 12 includes an outwardly curved front contact wall 16 , parallel side walls 18 , parallel top and bottom walls 20 and a rear wall 22 perpendicular to the side walls 18 and at an angle relative to the front wall 16 . This angle of the rear wall 22 relative to the side walls gives each side wall 18 a trapezoidal shape. The fixing portion 14 protrudes from the middle of the rear wall 22 and includes a top wall 24 and a parallel bottom wall 26 extending continuously from the top wall and the bottom wall 20 of the trunk portion 12 . The top wall 24 contains a blind hole 28 above and extending towards the rear wall 22 of the trunk 1...

Abstract

An apparatus and method for reducing the noise generated by colliding conveyor carriers is disclosed which comprises urethane bumpers and a method of attaching same to portions of the carriers that do not make contact with other carriers when the carriers are accumulated. The bumpers extend from the carriers a sufficient distance to contact a similar bumper on an adjacent carrier when one carrier rolls up against another. The bumpers do not prevent the normally contacting portions of the carriers from coming into contact, but merely absorb a portion of the kinetic energy of the moving carrier to reduce the noise generated when the contacting portions of the trolleys do meet, and the presence of these bumpers does not adversely affect the spacing of the carriers in the accumulation line.

Description

technical field [0001] The present invention relates to a method and apparatus for reducing the noise caused by carriers colliding with each other in an accumulation section of a conveyor line, and more particularly to a method and apparatus for reducing the noise caused by carriers colliding with each other in the accumulation section of a conveyor line, and more particularly to a method and apparatus for reducing the spacing between carriers on the accumulation line without appreciable changes Down. A method and apparatus for reducing noise caused by carrier collisions. Background technique [0002] Powered and free conveyors are well known systems consisting of powered and free rails and a pair of trolley rails capable of moving along the free rails and supporting the carriers. Each guide trolley in the power and free system includes a travel stop that extends toward the power rail and engages a finger carried by a moving chain on the power rail. When the finger engages...
