Abstract

Abstract A bidirectional travelling device for side sorting of articles in a flexible path transporting system made of at least one support fastened to a guide tow element of the system. Each support is made of a channel iron which is positioned to transversely with respect to the flexible path. The travelling device also includes a swiveling member positioned on each support for loading the article to be sorted. The swiveling member is made of two complementary, fork-shaped elements facing and interpenetrating one another. The fork-shaped elements pivot on sideboards of the channel iron. Due to gravity, the elements are in a horizontal, stable equilibrium position to define a plane for supporting the article. The travelling device further includes a scheme for actuating and resetting the swiveling member for rotating and raising the respective fork-shaped elements causing the downward discharge of the article transverse to the flexible path transporting system. The fork-shaped element thereafter returns to the equilibrium position due to the influence of gravity, causing the switching member to be reset.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 156 words
A bidirectional travelling device for the side-sorting of articles in a flexible path transporting system, comprising: at least one support fastened to a guided tow element of the system, each support being made of a channel iron having two side boards, the channel iron being disposed transversely with respect to the flexible path; a swiveling member disposed on each support, on which the article to be sorted is loaded, the swiveling member comprising two complementary, fork-shaped elements facing and interpenetrating one another and pivoting on the side boards, whereby the elements are in a horizontal, stable equilibrium position due to gravity to define a plane supporting the article; and means for actuating and resetting the swiveling member, for rotating and raising the respective fork-shaped elements, causing downward discharge of the article transverse to the flexible path transporting system, the fork-shaped element thereafter returning to the equilibrium position due to gravity, whereby the swiveling member is reset.
Claim 2
Dependent Claim 156 words
A bidirectional travelling device for the side-sorting of articles in a flexible path transporting system, comprising: at least one support fastened to a guided tow element of the system, each support being made of a channel iron having two side boards, the channel iron being disposed transversely with respect to the flexible path; a swiveling member disposed on each support, on which the article to be sorted is loaded, the swiveling member comprising two complementary, fork-shaped elements facing and interpenetrating one another and pivoting on the side boards, whereby the elements are in a horizontal, stable equilibrium position due to gravity to define a plane supporting the article; and means for actuating and resetting the swiveling member, for rotating and raising the respective fork-shaped elements, causing downward discharge of the article transverse to the flexible path transporting system, the fork-shaped element thereafter returning to the equilibrium position due to gravity, whereby the swiveling member is reset.
Claim 3
Dependent Claim 76 words
The bidirectional traveling device of claim 1, wherein each of the fork-shaped elements have bent ends which oppose one another and the means for actuating and resetting the swiveling member comprising two actuators provided at discharge points located on the flexible path transporting system and two cam elements, respectively fastened at the bent ends of the fork-shaped elements, the actuators, when activated, engage the respective cams and thereby rotate the fork-shaped elements and side-sort the article.
Claim 4
Dependent Claim 13 words
The bidirectional traveling device of claim 2, wherein the actuators are electrically activatable.
Claim 5
Dependent Claim 21 words
The bidirectional traveling device of claim 2 wherein said cam elements are integral to the opposite ends of said fork-shaped elements.
