Vertical Conveyor Slot for Variable-Size Checkout Goods Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-service devices for storing and dispensing goods near checkout systems are inefficient in accommodating goods of different sizes due to space constraints and design limitations, such as the use of paternoster-like conveyors that restrict size variability.
Innovation Solution
A self-service device featuring two conveyors that form a vertical conveyor slot for goods transport via frictional engagement, allowing for the efficient transfer of goods of varying sizes from a horizontal storage unit to an output position above the checkout counter, without the need for transverse webs that limit pack size, and incorporating a dialing device and output unit for secure and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If paternoster-like conveyors with crossbars are used, then goods can be transported vertically, but only cigarette packets in a certain size range can be stored and dispensed
Solution Approach 1:
The patent changes the fundamental parameter of the conveyor mechanism from a rigid paternoster structure with fixed crossbars to a flexible belt system. This allows the conveyor to adapt to different goods package sizes by adjusting the belt positioning and engagement points, eliminating the size restrictions inherent in the crossbar design.
Solution Approach 2:
The invention introduces dynamic elements through the use of belts that can move and adjust their position differently from the rigid paternoster structure. The belts can independently engage and disengage from goods packages, allowing for versatile handling of different sized items without requiring structural changes to the conveyor framework.
2Ease of operation
If self-service devices are arranged in front of the cash register, then customer access is improved, but installation space requirements increase and cashier clarity is restricted
Solution Approach 1:
The patent relocates the storage unit from the horizontal plane in front of the cash register to the vertical space above it. By utilizing the upward vertical dimension, the device maintains customer accessibility while eliminating the need for additional floor space, thus resolving the contradiction between ease of operation and area requirements.
3Adaptability or versatility
If transverse webs are used on conveyors to limit pack size, then goods can be controlled, but goods packages of different sizes cannot be accommodated
Solution Approach 1:
The invention replaces the fixed geometric constraint of transverse webs with a flexible belt-based control mechanism. The belt system can adjust its engagement parameters such as position, tension, and contact points to accommodate different pack sizes without requiring physical modifications to the conveyor structure, thus eliminating the need for size-limiting webs.

AI summary
The device (5) with cash machine (1) has a conveyer system with two conveyors, which forms partly parallel and concurrent conveyor slot for the selected goods packing. The conveying slots are vertically arranged. The selected goods packing are looped around in area of the inlet jaw of the conveying slot. The supply unit (6) and an output unit (9) with the conveyer system are arranged below the goods conveyor band (10) in extending installation position.
