US 4,541,766 A · Device for handling packs of elongated articles, especially lumber packs

Abstract

A support or jig (6) for handling packs including elongated articles, especially lumber packs (2a,2b), is adapted to support the lumber pack during the handling and to be brought to an appropriate position in front of an input opening in a rack (1) for the transfer of a loading pack between the handling device (6) and the rack (1). During the transfer between the handling device and the rack, the weight of the pack gives rise to a tilting moment. Therefore, the device (6) is provided with supporting arms (10a,10b) which securely engage supporting means (11a-11e) in the rack (1) so that the handling device (6) during the transfer operation is supported in the area of the rack openings. The arms are locked in their extended positions by the load and hold the jig next to the rack, even if a tilting moment is created during transfer.

Dependent claims

A jig (6) for handling of packs including elongated articles, especially lumber packs (2a, 2b), comprising a frame having transverse transport rollers (7a-7e) adapted to support the packs during handling, the frame being positioned in front of a rack opening in a rack, the rack having rollers (4a, 4b) for the transport and support of the packs so that the transfer of the pack between the jig (6) and the rack (1) can take place by rolling the pack from the rollers (7a-7e) on the jig (6) to the rollers (4a-4b) in the rack (1), the invention being characterized in that the jig (6) further comprises supporting arms (10a, 10b), each arm having a substantially hook-shaped means (12) at one end adapted for hooking onto a horizontal supporting iron (11a-11e) in the rack (1) below the rollers, the arms constituting a support for the device in a vertical direction during the transfer of the article to the rack, and including means for resisting the reaction forces which can develop in the horizontal direction when movement of the pack is blocked during the transfer, the resistance being created by a skewed relationship between each arm and a guide means.

A device for handling of elongated articles, such as lumber packs, comprising:

(a) a frame for holding the article, allowing elevation of the frame and article for off-loading, the frame including at least one support arm guide means;
(b) a plurality of spaced, parallel, transverse rollers on top of the frame for supporting the article and allowing rolling movement of the article in a predetermined direction;
(c) at least one support arm extensible from the guide means of the frame in the predetermined direction, the arm extending below the rollers to avoid interference with movement of the article above the arm on the rollers from the frame to the rack;
and
(d) connecting means on an end of the arm for securely connecting the arm and frame to a horizontal support iron of a storage rack,
wherein the arm constitutes a support for the device in a vertical direction during transfer of the article to the rack and an abutment for the jig against reaction forces which can develop in the horizontal direction when movement of the article is blocked during the transfer from the frame to the rack, the resistance being created by a skewed relationship between the arm and guide means.
