Solution Overview

Problem

Conventional box packing devices face issues with articles, such as sealed bags, expanding and sticking out of boxes during packing, leading to potential damage and improper packing due to rotation within the boxes.

Innovation Solution

A box packing device incorporating a push-in mechanism, retention mechanism, guide, and control unit that temporarily increases the distance between the box and guide after pushing articles in, and optionally tilts the box to prevent articles from getting caught and rotating, using a shutter to facilitate smooth packing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If articles are pushed into boxes using a stopper to ensure they do not stick out, then packing density is improved, but articles may expand and get caught on the guide causing rotation and damage

Engineering Contradiction:
Improvepacking densityVSAvoidarticle integrity
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The control unit temporarily increases the distance between the box and guide before the articles have a chance to expand and contact the guide. This preliminary action prevents the harmful interaction between expanded articles and the guide structure, eliminating the rotation problem while maintaining efficient packing

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the position of the box relative to the guide during the packing process. By temporarily increasing the distance between the box and guide, the system adapts to the expanding articles without causing them to get caught on the guide, thus preventing rotation and damage

Inventive Principle:
Principle #15Dynamics

2Productivity

If the box is lowered repeatedly to push more articles into the box, then productivity is improved, but articles may rotate inside the box causing improper packing

Engineering Contradiction:
Improvepacking speedVSAvoidpacking accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The control unit temporarily increases the distance between the box and guide as a preliminary action before lowering the box for the next article. This prevents articles from getting caught on the guide during the lowering operation, ensuring proper packing accuracy is maintained throughout the high-speed packing process

Inventive Principle:
Principle #10Preliminary action

AI summary

It is an object of the present invention to provide a reliable box packing device that inhibits the occurrence of a problem where, when packing an article into boxes, the article end up rotating in the boxes. A box packing device (10) includes a push-in mechanism (50), a retention mechanism (30), a guide (70), and a control unit (100). The push-in mechanism (50) pushes, into a cardboard box (C) that is in a state in which an opening (Op) thereof faces sideways, the article (A) through the opening (Op). The retention mechanism (30) retains the cardboard box (C) that is in a state in which the opening (Op) faces sideways and lowers the cardboard box (C) after the article (A) have been pushed into the cardboard box (C) by the push-in mechanism (50). The guide (70) opposes the opening (Op) and is a member for preventing the article (A) from falling out from the opening (Op) of the cardboard box (C) that has been lowered by the retention mechanism (30). The control unit (100) temporarily increases the distance between the cardboard box (C) and the guide (70) after the article (A) have been pushed into the cardboard box (C) by the push-in mechanism (50).
