Embodiment Construction

[0033] Figure 1A with 1B Shown in is a form of a split checkweigher embodying features of the invention. Checkweigher 30 includes an endless conveyor belt 32 and a weighing table or scale 34 supported in a frame 36 . A conveyor belt 32 runs around between a drive sprocket and an idler sprocket with a drive shaft 38 and a driven shaft 39 at opposite ends of the conveyor path. A drive motor 40 coupled to a drive shaft 38 drives the conveyor belt 32 in a direction 42 of belt travel. The weighing platform 34 is located below the conveyor belt 32 and forms a weighing area 43 on a certain part of the transport path. The conveyor belt 32 is an endless belt made up of a series of belt modules 44 joined together at hinge joints 45 . In the weighing area 43 , the products on the conveyor belt are weighed by means of a weighing table 34 . The conveyor belt 32 has product pushers in the form of pins 46 in slots 48 extending along the width of the belt modules 44 . During transport, ...

Abstract

The invention discloses a checkweigher conveyor belt. The checkweigher conveyor belt comprises an endless belt body, a plurality of product support slats and a product pusher, wherein the endless belt body advances in a conveyor belt traveling direction along a conveying path, and has an outer surface extending along a width of the belt body from a first side edge to an opposite second side edge; the endless belt body comprises slots extending through the belt body in a width direction of the belt body; the plurality of product support slats are spaced apart along the length of the belt body in the travelling direction of the belt body; each slat extends in the width direction of the belt body; each of the slats is movable in a direction perpendicular to the outer surface of the belt body from a first position on the outer surface of the belt body to a second position away from the outer surface of the belt body; the slats comprise slots aligned with the slots through the belt body; and the product pusher extends through the aligned slots and can translate along the aligned slots. The checkweigher conveyor belt can be used for weighing pushed products.

Description

technical field [0001] The present invention generally relates to a checkweigher conveyor belt. Background technique [0002] In many production lines, the product being conveyed is weighed by a checkweigher, and the weight is used for grading, batching, labeling, pricing or to check the quality or consistency of the product. [0003] Checkweighers are usually located on conveyor lines so that they can be "on line" and possibly "in motion" as well, ie, weigh the product without stopping its flow. A conventional checkweigher consists of a short length of conveyor belt running over a checkweighing platform on a checkweigher that freely supports the conveyor belt and the product being conveyed while measuring its weight. Typically, the product is conveyed to the checkweigher via an interstitial conveyor, which accelerates the product to create gaps between successive products. This way only one product stays in the area of ​​the checkweigher at a time. Once weighed, the prod...
