Bottle Line Accumulation Conveyor with Independent Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accumulation apparatuses in bottling plants lack sufficient operating flexibility and efficiency, leading to increased production downtime and costs due to the need to temporarily stop conveyors and operating machines during container accumulation.
Innovation Solution
An accumulation apparatus with a control logic unit that manages independent drive systems for upstream and downstream conveyors, allowing flexible operation modes (by-pass, partial accumulation/recovery, and total accumulation/recovery) to maintain production continuity and reduce conveyor stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If common conveying means are used to connect operating machines in a single production line, then the containers can be conveyed between operating machines, but the entire line must stop when one operating machine detects a problem
Solution Approach 1:
The production line is segmented into multiple independent sections by introducing an accumulation apparatus with separate upstream and downstream conveyors. This allows the upstream conveyor to continue feeding containers to the accumulation unit while the downstream conveyor handles distribution to subsequent machines, enabling isolated operation of problematic sections without stopping the entire line.
Solution Approach 2:
The accumulation apparatus acts as an intermediary buffer between upstream and downstream operating machines. It temporarily stores containers and regulates flow between sections, allowing upstream machines to operate independently from downstream machines. This mediator enables continuous production by decoupling the synchronization requirement between adjacent machines.
2Reliability
If the accumulation unit receives containers from the upstream conveyor and feeds the downstream conveyor, then containers can be accumulated during downtime, but the directing assembly requires complex control logic to manage multiple operation modes
Solution Approach 1:
The directing assembly incorporates dynamic control capabilities that allow it to switch between multiple operation modes (by-pass mode, partial accumulation/recovery mode, total accumulation/recovery mode) based on real-time production needs. This dynamic adaptability enables the system to optimize performance for different scenarios while managing complexity through standardized control logic for each mode.
Solution Approach 2:
The system changes operational parameters (such as conveyor speeds, directing assembly positions, and accumulation unit capacity) depending on the selected mode. By defining distinct parameter sets for each operation mode, the control logic manages complexity through systematic parameter management rather than complex conditional routing in all scenarios.
3Adaptability or versatility
If the upstream conveyor and downstream conveyor are operated at different speeds, then flexible accumulation and recovery operations can be performed, but the drive systems become more complex with independent control requirements
Solution Approach 1:
The drive systems are designed with dynamic control capabilities that allow independent speed adjustment of upstream and downstream conveyors. This dynamic speed control enables flexible accumulation (when downstream speed is lower) and recovery (when downstream speed is higher) operations. The complexity is managed through coordinated control that maintains synchronization when needed while allowing independent operation when flexibility is required.

AI summary
Accumulation apparatus (1) for a bottling plant (100) provided with a plurality of operating machines (101-106), comprising an upstream conveyor (2), susceptible to receive containers from an upstream machine (103), a downstream conveyor (3) susceptible to feed with the containers a downstream machine (105), a unit (4) for accumulating the containers and a directing assembly (5), which is arranged to intercept the upstream conveyor (2) and the downstream conveyor (3), is configured to pick up the containers from the upstream conveyor (2) and it is susceptible to selectively feed one of the downstream conveyor (3) and the accumulation unit (4). The accumulation apparatus (1) comprises replenishment means (6), which are placed as a connection between the accumulation unit (4) and the downstream conveyor (3) at a replenishment station (61) downstream of the directing assembly (5), and they can be actuated to pick up the container from the accumulation unit (4) in order to feed the downstream conveyor (3). Furthermore, the upstream conveyor (2) is actuated by first drive means at a first operating speed (V1) and said downstream conveyor (3) is actuated by second drive means at a second operating speed (V2).
