1. Field of the Invention
The subject invention relates to an attachment system for securing conveyor components to a conveyor.
2. Description of the Prior Art
Conveyors of numerous designs have been used in the past to transport articles from one area to another. Known conveyors have employed endless belts, segmented slats, slider beds and other elements to move objects along their path of transport. During the field installation phase of conveyor systems, it is often necessary to add attachment points, typically unistrut type “framing channel”, to the conveyor side guards or frame. In addition to providing structural support to the conveyor system, these attachment points are used to secure wiring conduit, control boxes, photocell brackets, motor control devices, etc., to the conveyor side guards. Because conveyors are installed in unique locations and applications, providing all factory installed attachment points is not practical. Factory installed attachment points add additional weight, materials and cost to the conveyor system and may not be needed at every location a conveyor system is installed.
It is known in the art to have short sections of framing channel that are welded in the field at the required location to attach field mounted components. Such known processes involve grinding off the powder coat paint to provide a welding surface, then welding the framing channel to the conveyor followed by touch up painting. This field work is time consuming and adds additional cost to the installation of the conveyor system.
In view of the above, the present invention is directed to an attachment system for securing conveyor components to a conveyor that is disposed between a pair of side guards or frames. The system includes at least one side guard that is U-shaped and has first and second side guard ends that extend perpendicularly from the opposite ends of a flat wall portion to a distal end. The first side guard end includes a first lip that extends from the distal end of the first side guard end to define a grooved portion. The second side guard end includes at least one end guard opening defined therein. At least one framing channel that defines a channel portion extends between first and second channel ends and is disposed between the first and second side guard ends. The first channel end includes a projection portion that extends from the first channel end to engage to the grooved portion to secure the first channel end adjacent the first side guard end. At least one tab extends outwardly from the second channel end to engage the end guard opening to secure the framing channel to the side guard.
The present invention is further directed to a method for securing conveyor components to a conveyor that is disposed between a pair of side guards. To begin, at least one tab extending outwardly from the second channel end is angularly inserted into the end guard opening. The first channel end is then moved angularly towards the first side guard end while the at least one tab remains in the end guard opening of the second side guard end. Next, a biasing adaptor is angularly inserted into the grooved portion to secure a portion of the biasing adaptor within the grooved portion. Finally, the biasing adaptor is secured to the framing channel to secure the framing channel to the side guard.
The present invention provides for a universal framing channel that can be attached with no welding or touch up painting. The framing channel may be supplied in various lengths to accommodate various side guard heights and can be field mounted at any location along the conveyor.
