Solution Overview

Problem

Existing product handling devices in packaging machines use pivotally mounted compression elements that apply impact forces, leading to reduced production output, product damage, and production disruptions due to abrupt compression and movement of products.

Innovation Solution

A product handling device with a movably mounted compression element that translates along the transport direction, allowing for gentle and continuous compression of product groups, synchronized with the transport movement, using a drive unit and guide track to ensure smooth and uniform compression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a pivotally mounted compression element is used to apply impact force to product groups, then compression is achieved quickly, but product damage occurs and production output is reduced

Engineering Contradiction:
Improveproduction outputVSAvoidproduct damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The compression element is made movable along the transport direction to synchronize with product movement, transforming the static compression approach into a dynamic one that adapts to the continuous flow of products, thereby eliminating impact forces and preventing product damage while maintaining high productivity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The compression element moves along with the products before compression is applied, establishing synchronous movement in advance. This preliminary synchronization ensures that compression occurs without relative motion or impact, preventing product damage while maintaining continuous production flow

Inventive Principle:
Principle #10Preliminary action

2Productivity

If a pivotally mounted compression element is used for compression, then compression force is applied, but the return time reduces production output

Engineering Contradiction:
Improveproduction outputVSAvoidreturn time
Core Design Contradiction:
ProductivityVSDuration of action of moving object

Solution Approach 1:

The compression element moves continuously along the transport direction with the products, eliminating the need for return movements. Compression is applied continuously over the movement path rather than in discrete cycles, maintaining uninterrupted production flow and eliminating time loss associated with element repositioning

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If impact force is applied to compress product groups, then compression is achieved quickly, but individual products move out causing production disruptions

Engineering Contradiction:
Improveproduction reliabilityVSAvoidproduct movement disruption
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

By making the compression element movable along the transport direction to match product speed, the system eliminates relative motion between the compression element and products. This dynamic synchronization prevents products from being displaced or disrupted during compression, ensuring continuous reliable production

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable compression element acts as an intermediary that moves with the products rather than imposing force from a fixed position. This intermediary approach allows compression to be applied smoothly without causing product displacement or production disruptions

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention relates to a product handling device for a packaging machine, comprising at least one transport unit (14) for transporting products (16) along a transport direction (18) of the transport unit (14) and at least one compression unit (20) for compressing individual product groups, in particular product rows oriented transversely to the transport direction (18), of the products (16) transported by means of the transport unit (14), wherein the compression unit (20) has at least one compression element (22), in particular a plunger, which is movably mounted, in particular translationally. It is proposed that the compression element (22) be movable, in particular at least temporarily, together with, preferably synchronously, at least one transport element (24) of the transport unit (14), on which the products (16) can be arranged, along the transport direction (18).
