Technical Field
The present invention relates to an electrically driven conveyor. More particularly, the present invention relates to infeed and outfeed assemblies for a conveyor to transfer conveyed articles onto and off of the conveyor, and position limiters for ensuring proper engagement between the conveyor belt and the drive.
Background
Electrically driven conveyors are used to convey articles. Position limiters, such as those described in U.S. patent No. 7,850,562, the contents of which are incorporated herein by reference, are used in low tension, positive drive belt drive systems to ensure proper engagement of the belt and the drive sprockets by controlling the position of the belt during the drive tooth switching process. The position limiter may be positioned against the belt near the exit point. Examples of position limiters include scrapers (scrapers), rollers (rollers), and shoes (shoes).
The current position limiter is secured to a mounting shaft that may trap dirt and debris and prevent removal and/or replacement of the position limiter. In addition, current position limiters are typically placed at a location where the conveyor belt will naturally be away from the drive sprocket when no pretension is applied, which is typically at a wrap angle of 165 ° from where the belt enters the drive sprocket. If a belt flight is used, the position limiter therefore contends for the same space as the belt flight. In addition, the position limiter must be axially aligned with the drive sprocket, requiring a locking collar or fastener that can become a harborage for bacteria, thus posing a risk to food safety. In addition, the conveyor belt with baffles makes the use of position limiters difficult.
Disclosure of Invention
An end assembly for a conveyor includes opposed end plates, a drive extending between the end plates, and a position limiter assembly extending between the end plates below the drive for ensuring proper engagement of a conveyor belt with the drive. The position limiter includes a series of spaced rollers mounted to and spaced from a mounting bar extending between the end plates.
According to one aspect, a conveyor comprises: a frame comprising opposed end plates at the ends of the conveyor, each end plate comprising an upper opening for mounting a drive shaft and a lower opening comprising a receptacle for mounting a position limiter assembly; and a position limiter assembly mounted in the frame. The position limiter assembly includes a mounting bar extending from a first end to a second end, a plurality of rollers mounted to a plurality of roller mounting arms extending from the mounting bar, and a mounting portion for mounting the mounting bar between the end plates.
According to another aspect, a position limiter assembly for a conveyor includes: a mounting rod extending from a first end to a second end; a first assembly mounting arm extending upwardly from a top of the mounting bar at the first end; a mounting portion for mounting the mounting bar to a conveyor frame; and a plurality of rollers mounted to and spaced from the mounting bar at selected intervals along the length of the mounting bar.
According to another aspect, a mounting arm for a position limiter assembly includes: a base; a first end for connecting the mounting arm to a mounting rod; and a second end of a belt groove for receiving a roller forming a position limiter, the second end of the belt groove including an operation groove and an open installation groove intersecting the operation groove at an angle.
