Abstract

Abstract In a system for transporting articles, such as packaging containers, between work stations by means of an endless conveyor having spaced supports thereon and holders for the articles mounted either directly on the conveyor or on the supports attached to the conveyor, the improvement of utilizing permanent magnets for securing the holders in a readily releasable manner. A method is provided which requires that the magnetic field be sufficient to resist gravity separation but insufficient to prevent manual separation of the holders from their supports.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 124 words
Apparatus for transporting different sized containers comprising: a. an endless conveyor comprising two parallel members spaced from each other; b. a plurality of supports spaced apart along the conveyor; c. a plurality of different sized, rEmovable container holders each of which is adapted to be mounted on the supports, each of said holders being in the form of a cradle having end walls spaced from each other a distance which is less than the total length of a container, each end wall having a recess formed therein adapted to contact a surface portion of one of said containers to support said one container in a horizontal position; and d. permanent magnets between the supports and the holders for securing the holders to the supports.
Claim 2
Dependent Claim 124 words

Claim 3
Dependent Claim 87 words
Apparatus for transporting articles comprising: a. conveying means including an endless conveyor; b. a plurality of article holders; c. a plurality of permanent magnets for attaching each of the holders to the conveying means; and d. a support for each article holder, said support having a slot formed in its surface for holding one of said magnets, each holder having an aperture and each support having a locating pin for insertion into the aperture to orient the holder in a predetermined position with respect to the conveyor.
