Abstract
POWER AND FREE CONVEYOR SYSTEM
Abstract of the Disclosure A power and free conveyor system comprising a power track, a conveyor movable along said power track, a free track, a plurality of carriers movable along said free track and interengaging means between said conveyor and said carriers. At least one module is provided and comprises a body having hooks on a back wall thereof.
The carrier has a generally vertical central frame extend-ing downwardly including spaced side portions which are generally vertically aligned with the free track. An upper pair of arms extends transversely from the central frame and a cross bar joins said arms. The module extends between the side portions of the central frame with the hooks engaging the cross bar. A pair of lower arms extends transversely from the central frame and a bar between the ends of the lower arms engages the back wall of the module to stabilize the module.

`` lOS4S47 Description Referring to Fig. 1, the invention relates to a power and free conveyor system particularly adapted for transporting modules M which have side walls 10, top and bottom walls 11, 12, and a rear wall 13. The module may further include adjustable shelves 14. In addition, the module has integral hooks 15 on the rear wall 13 which are commonly used to engage the module with the cross bar on the wall of the room in which the module is being used for storing various goods.
The power and free conveyorsystem embodying the invention comprises a power track 16 in which a chain conveyor 17 operates. The power track 16 is telescoped ' within a larger track 18, the lower portion of which forms a carrier or free track for a plurality of carriers 20.
Each carrier 20 includes a front trolley 21 having wheels thereon engaging the track 18 and a rear trolley 22 ` similarly having wheels thereon. Interengaging means provided between the conveyor chain 17 and the rear trolley 22 in accordance with well-known construction ` comprise a pusher 23 which is trapped between a pusher dog 24 and a holdback dog 25 all in accordance with conventional construction as shown, for example, in United States Patent 3,08L,712.
;' 25 Each carrier 20 further includes a tie bar 25a extending between the trolleys ?1, 22. In addition, the carrier 20 includes brackets 26 that extend downwardly .` , lOS4S4'7 from longitudinally spaced points on the tie bar 25a to support rollers 27 that have their axes extending horizontally and transversely of the path of movement of the carrier. Each carrier further includes a central frame 28 that is made of a single piece of metal having a channel-shaped cross section and includes vertical side portions 29 connected by a horizontal central portion 30. At the areas of juncture 31 of the side portions 29 and horizontal portion 30, the frame 28 is curved for engagement with the rollers 27.
Referring to Fig. 3, the carrier 28 further includes upper transverse arms 32 that extend from the side portions 29 of the central frame 28 and have a cross bar 33, having a circular cross section, extending between their free ends. An angle 34 reinforces the cross bar 33 ,so that it will support the load when the hooks 15 on the module M engage the cross bar.
The central frame 28 further includes lower transverse arms 35 that extend in the same direction as 20 the upper arms 32 and have their free ends interconnected ~ -by a bar 36 that forms contact means for the intermediate , portion of the rear wall 13 of the module M.
In order to further increase the strength of the frame 28, struts 37, 38 are formed between the side arms 32, 35 and the side portions 29 by bending and welding a single rod to the respec~ive arms and portions.
.
, .
In addition, rectangular handles 39 are provided on the side portions 29 and extend transversely in directions opposite to the side arms 32, 35 to facilitate the mounting and removal of the module M from the carrier 20.
The carrier further may include destination code means 40 in accordance with conventional construction.
In operation, the module M is lifted manually or by an elevator truck to a position between the side portions 29 to bring the hooks 15 into position for engage-ment with the cross bar 33. When the module M is so suspended, the intermediate portion of the rear wall 13 engages the bar 36 thereby stabilizing the module M
within the carrier. The interaction of the cross bar 33 and bar 36 forms a force couple that stabilizes the load ., and insures its vertical movement along the track.
`, When a portion of the track is inclined, gravity . j .
will cause the frame 28 to be lifted, as shown in broken lines in Fig. 2, so that the load is maintained vertical within the limits of space between the rollers 27 and the bar 25~.
