Solution Overview

Problem

Conventional can filling/seaming devices require a long linear intermediate conveyance path, leading to a non-compact arrangement, complex installation processes, and increased costs due to the need for positional and timing adjustments, as well as the use of special driving devices to prevent liquid content spillage during conveyance.

Innovation Solution

Integrating a filler and seamer through a forwarding turret that provides a circular conveyance path for cans filled with liquid content, eliminating the need for a linear intermediate path and allowing for simplified installation by using a common frame with the forwarding turret, which includes a lid supply part and ensures limited acceleration to prevent spillage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a linear intermediate conveyance path is used between filler and seamer, then liquid content spillage is prevented, but device size increases and installation complexity increases

Engineering Contradiction:

Improveprevention of liquid content spillageVSAvoiddevice size

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The patent replaces the linear intermediate conveyance path with a circular conveyance path implemented through a forwarding turret. This curved path allows cans to be conveyed from the filler to the seamer while maintaining controlled acceleration and centrifugal forces that prevent liquid spillage, while simultaneously reducing the overall device footprint by eliminating the need for a long linear conveyance path.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The invention transitions from a one-dimensional linear conveyance path to a two-dimensional circular conveyance path using the forwarding turret. This dimensional change enables the can to be conveyed through multiple positions (including overhead positions) while maintaining spillage prevention, and allows the filler and seamer to be positioned closer together in space.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If a linear intermediate conveyance path is used between filler and seamer, then liquid content spillage is prevented, but installation time increases due to positional and timing adjustments

Engineering Contradiction:

Improveprevention of liquid content spillageVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The forwarding turret integrates multiple functions into a single device: it serves as both the conveyance mechanism and the timing synchronization device. The turret receives cans from the filler, conveys them through a circular path that prevents spillage, and delivers them to the seamer, while its rotational position automatically provides timing synchronization, eliminating the need for separate positional and timing adjustment mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The forwarding turret performs multiple functions simultaneously: conveyance of cans, prevention of liquid spillage through controlled circular motion, timing synchronization between filler and seamer, and positioning of cans for lid application. This multi-functionality reduces the number of separate components and adjustments needed during installation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If special driving devices are used for timing adjustment, then timing synchronization is improved, but manufacturing cost increases

Engineering Contradiction:

Improvetiming synchronizationVSAvoidmanufacturing cost

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The forwarding turret uses its own rotational motion and positioning mechanism to automatically achieve timing synchronization with the filler and seamer. The turret's design inherently provides the necessary timing coordination through its circular conveyance path and positioned delivery point, eliminating the need for separate special driving devices or complex timing adjustment mechanisms that would increase manufacturing cost.

Inventive Principle:

Principle #25Self-service

AI summary

A can filling/seaming device that fills a can with a liquid content and seals the can with a lid by double-seaming allows a filler and a seamer to be integrated in a compact arrangement. A can filling/seaming device includes a filler that fills a can with a liquid content while conveying the can by rotation of a filling turret, a seamer that attaches a lid to the can filled with the content by double-seaming, and a forwarding turret provided between a carrying-out position of the filling turret and a carrying-in position to the seamer to circularly convey the can filled with the content, wherein a lid supply part is provided on the forwarding turret.
