Four-Runner Weighbridge for Slaughter Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slaughter product weighing devices using two coaxial runners on a weighbridge result in reduced weighing time due to the need for shorter weighbridge lengths, leading to less accurate and reliable weight measurements due to interference from product swaying and vibration filtering adjustments.
Innovation Solution
Configuring four runners in pairs with parallel tracks, allowing simultaneous rolling onto and off the weighbridge, enabling a longer weighbridge length and thus longer weighing time, while maintaining stability and accuracy through distinct track widths and inclined surfaces for centring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If four runners are provided behind each other to suppress product swaying, then product carrier stability is improved, but the weighbridge length must be shortened to prevent simultaneous rolling of runners from successive carriers, reducing weighing time
Solution Approach 1:
The patent divides the single track into four separate parallel tracks, with each track receiving one runner. This segmentation allows the runners to be arranged behind each other while maintaining independent rolling paths, enabling simultaneous rolling onto the weighbridge without interference between successive product carriers.
Solution Approach 2:
The patent transitions from a single-track configuration to a multi-track parallel configuration, adding the dimension of lateral separation. This allows runners to be positioned both behind each other in the conveying direction and separated laterally, creating sufficient space for simultaneous rolling onto the weighbridge.
2Reliability
If the weighbridge length is shortened to prevent simultaneous rolling of runners, then runner interference is reduced, but the time available for weighing is reduced and weighing accuracy decreases
Solution Approach 1:
By segmenting the single track into four parallel tracks, the patent eliminates interference between runners of successive product carriers. Each runner has its own dedicated track, allowing the weighbridge to be lengthened without causing simultaneous rolling conflicts, thus ensuring both reliability and precision.
3Stability of the object's composition
If four runners are arranged behind each other, then product swaying is suppressed, but the distance between rear runner and front runner of successive carriers becomes smaller, requiring shorter weighbridge length
Solution Approach 1:
The patent segments the runner arrangement into four separate parallel tracks, allowing each runner to be positioned behind the corresponding runner of the previous carrier without lateral interference. This enables the weighbridge to extend sufficiently for accurate weighing while maintaining the stable behind-each-other runner configuration.

AI summary
The invention provides a device for weighing slaughter products, comprising a guide which extends along a conveying path, product carriers which can be moved along the guide and which are configured for suspending slaughter products therefrom, and weighing means comprising a weighbridge. Each product carrier comprises four runners, two of which runners are provided behind the other two runners, seen in the direction of movement. The four runners are configured to roll over the weighbridge along respective tracks during a weighing interval upon movement of the product carrier, which tracks extend parallel to each other, wherein the four runners roll over the weighbridge during the weighing interval and wherein the weighbridge and the four runners are configured such that the runners will roll simultaneously onto the weighbridge and simultaneously off the weighbridge.
