Abstract
An apparatus for buffering or temporarily storing articles is disclosed. The apparatus includes a feed for the articles with at least one endless flexible member moving past the feed. Doglike elements which engage the articles and between which the articles are transported are movable together with the flexible member. One or more guide members for guiding the flexible member during changes of direction are provided with a discharge for discharging an article from between two doglike elements. A mechanism for diminishing the impact to the articles is provided wherein the guide members are movable relative to the feed and/or discharge.
Claims15
An apparatus for buffering or temporarily storing articles, comprising:
- a feed for the articles;
- at least one endless flexible member movable past the feed;
- doglike elements which engage the articles and between which the articles are transported, and which elements are movable together with the flexible member;
- one or more guide members for guiding the flexible member during changes of direction;
- a discharge for discharging an article from between two doglike elements;
- and
- means for diminishing impact to the articles, wherein the guide members are movable relative to feed and/or discharge, wherein the impact diminishing means includes a drive member for an electric motor, whereby beginning and end of the linear movement is substantially impact free, wherein the electric motor is driven according to the formula s(t)=at +b sin (.omega.t+.phi.), wherein s(t) is the path covered in the transporting direction as a function of time t, and a, b, .omega. and .phi. are constants.
