Bale Packaging Device with Transverse Feed and Overlapping Cycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging technologies for pressed bales at baling presses are limited in capacity due to slow feeding and positioning processes, which hinder efficient packaging and preparation for the next pressing operation.
Innovation Solution
A packaging device with a feed device that rapidly feeds the upper and lower parts of the bale wrapping during or immediately after the discharge of a pressed bale, allowing for overlapping of discharge and feed processes, and enabling simultaneous or offset feeding of these parts in a straight alignment, thereby increasing capacity and improving packaging quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the upper part and lower part of the bale wrapping are fed sequentially with traditional feed devices, then the packaging process is simple to implement, but the packaging capacity is limited due to slow feeding speed
Solution Approach 1:
The bale wrapping is divided into multiple separate parts (upper part, lower part, side parts) that are fed independently and simultaneously. This segmentation allows parallel processing of different wrapping sections, significantly reducing total feed time and increasing packaging capacity compared to sequential feeding of a single continuous wrapping.
2Productivity
If the transport apparatus returns to its inoperative position before feeding the next bale, then the feed device has clear access to feed the upper part and lower part, but the packaging capacity is reduced due to idle time
Solution Approach 1:
The feed device prepares the upper part and lower part of the bale wrapping in advance during the transport apparatus's return movement. The wrapping parts are pre-positioned and ready for immediate feeding as soon as the transport apparatus completes its cycle, eliminating idle time and maintaining continuous operation.
Solution Approach 2:
The feeding operation is made continuous by overlapping the transport apparatus return movement with the feed preparation and positioning of the upper and lower parts. The feed device remains active throughout the cycle, preparing materials for the next bale while the current bale is being processed, thus eliminating idle time and maximizing productivity.
3Manufacturing precision
If a loading and unloading device is added to apply the side part of the bale wrapping, then the packaging quality is improved, but the device complexity increases
Solution Approach 1:
The transport apparatus is designed to perform multiple functions: it transports the pressed bale, applies the side parts of the bale wrapping, and coordinates with the feed device for the upper and lower parts. This multi-functionality eliminates the need for a separate loading and unloading device, reducing overall equipment complexity while maintaining packaging quality.

AI summary
A controllable packaging device (5) and a method relate to packaging compressed bales (6) on a baling press (2) with a bale-fixing element (11) and a multi-component bale envelope (7) including an upper part (8), a lower part (9) and optionally a sheath-type side part (10). The packaging device includes a fixing device (23) applying the bale-fixing element (11), a supply device (25) supplying the upper part and the lower part and optionally an envelope device (24) applying the side part to the compressed bales. The fixing device and optionally the envelope device are arranged on a transport apparatus (19) that travels along the compressed bale in an advancing direction (22). The supply device is arranged on the transport apparatus and supplies the upper part and the lower part with a supply movement oriented transversely to the advancing direction, from the outside into the baling press.
