Trigger Device for Heavy Goods Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing triggering devices for inclined storage shafts are inadequate for handling large and heavy goods, as they can be damaged by subsequent items and require high barriers to prevent rolling, leading to inefficiencies in dispensing and potential slipping of goods.
Innovation Solution
A triggering device with a lifting and pre-stop component and a blocking body featuring a permanent locking edge, which moves between release and blocking positions to safely lift and stop goods, using a drive system and a three-armed movement converter for adjustable operation, and includes a lock for rollover protection without direct contact with goods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock is moved above or below the storage compartment floor to release or block output, then the triggering device can control dispensing, but the lock can be damaged by subsequent piece goods and piece goods with high weight cannot be used
Solution Approach 1:
The triggering device is divided into two independent components: a lifting component that raises the piece good clear of the locking edge, and a separate locking component with the locking edge. This segmentation prevents the locking component from bearing the full weight and impact forces, as the lifting component handles the piece good manipulation while the locking edge only provides a blocking function.
Solution Approach 2:
The lifting component acts as an intermediary between the piece good and the locking edge. By introducing this intermediate element, the direct contact and force transmission between the piece good and locking edge are eliminated, protecting the locking mechanism from damage while enabling heavy piece goods to be handled.
2Reliability
If a high barrier is used to prevent subsequent piece goods from rolling over, then rollover prevention is achieved, but the device complexity increases and handling of large piece goods becomes difficult
Solution Approach 1:
The lifting component performs a preliminary action by raising the piece good above the locking edge before the locking component engages. This preliminary lifting action prevents subsequent piece goods from rolling over the locking edge, eliminating the need for high barriers and simplifying the overall device structure.
Solution Approach 2:
Instead of preventing rollover by increasing barrier height in the vertical dimension, the solution transfers the prevention mechanism to the vertical lifting motion of the lifting component. The piece good is lifted in the vertical dimension clear of the locking edge, achieving rollover prevention without requiring tall barriers.
3Ease of operation
If a lock is moved into the sliding path to block output, then dispensing control is achieved, but subsequent piece goods can hit the lock causing damage
Solution Approach 1:
The triggering device separates the lifting function and locking function into distinct components. The lifting component handles the piece good manipulation while the locking component with its locking edge provides blocking control. This segmentation ensures that the locking component is not directly in the impact path of subsequent piece goods, eliminating the harmful impact forces.
Solution Approach 2:
The lifting component serves as an intermediary that positions the piece good relative to the locking edge. By introducing this intermediate positioning mechanism, subsequent piece goods are prevented from directly impacting the locking component, thus protecting it from damage while maintaining dispensing control.

AI summary
The present invention relates to a release device and a method for dispensing a piece of goods. In known release devices, the weight of the piece of goods is limited, since pieces of goods sliding down can damage the device's locking mechanism if the weight is too high. The release device according to the invention comprises a lifting and pre-stop component (30) with an upper sliding surface (31), wherein the lifting and pre-stop component (30) is coupled to a drive (20) such that the sliding surface (31) can be moved via a sliding plane (GE) into a release position and to a height equal to the sliding plane (GE) into a locking position, and wherein the lifting and pre-stop component (30) has a stop (32) projecting above the sliding plane (GE) in the release position.In the sliding direction behind the lifting and pre-stop component (30) a locking body (40) is arranged with an upper locking body sliding surface (41), a locking edge (42) projecting beyond the sliding plane (GE) and a retractable lock (50), wherein the lock (50) is coupled to the drive (20) in such a way that the lock (50) can be moved under the locking body sliding surface (41) into a release position and over the locking body sliding surface (41) into a locking position, wherein the lock (50) is designed such that the locking edge (42) is formed in the sliding direction in front of the lock (50), so that in the locking position there is no contact between the unit load and the lock (50).
