Taiyo Co., Ltd. has introduced new equipment to replace its existing, aging sorting line.
With a focus on labor-saving, automation, and improved compression efficiency, we aim for a significant improvement in recycling rates and a reduction in transportation costs.
We will explain everything from the background of the introduction to the features of the equipment and future prospects.
◆ Background of Introduction
The existing sorting line had been in operation for 12-13 years and was showing significant signs of aging.
Therefore, we began considering a successor about 3-4 years ago, conducting facility tours and hearings at more than 10 locations in Japan.
After repeated discussions with the machinery trading company Fujitex Corporation, we selected the optimal configuration for our processing flow.
◆ New Equipment Configuration
The new equipment has the following configuration:
【Bag Breaker/Debagger】Automates the opening and removal of bags, significantly reducing manual work.
【Manual Sorting Line】Handles items that are difficult for machines to process, such as glass bottles.
【Flight Screen】Sifts out small fragments, cigarette butts, etc., to improve the working environment.
【Petris (PET Sensor Sorting)】Automatically separates only PET bottles using a transmission sensor and air power.
【Recycle 4 (Aluminum/Steel Separator)】Automatically separates aluminum and steel cans into two types and can also press them.
【PET Bottle Perforator】Dramatically improves compression efficiency by perforating bottles before compression (newly introduced).
【Compression Baler】Compresses each material into large bales to maximize transportation efficiency.
◆ Main Improvement Points
Based on the new equipment configuration, the following improvements were observed:
【Labor-Saving】Staff reduced from 8 to 5 members. The compact design of the machinery also made the workspace more efficient.
【Quality Improvement】The introduction of automatic sorting has stabilized product quality, and an improvement in net product profit is expected.
【Maintaining Processing Capacity】While achieving labor savings, the processing capacity remains the same as before at 20-25 m³/h.
【Compression & Transportation Efficiency】The new installation of the PET bottle perforator has improved the compression rate, contributing to the reduction of transportation costs.
【Improved Working Environment】The introduction of the flight screen has reduced dust and foreign matter, and the elimination of second-floor work has also reduced the burden on staff.
◆ Future Expectations
- Improved Recycling Rate: Enables the recycling of waste that was previously sent to landfills with the conventional line.
- Reduced Transportation Costs: Promotes optimization of shipping lots through improved compression efficiency.
- Effective Use of Resources: Automates processes that can be handled by machines, allowing people to focus on tasks that only they can do.
- Responding to New Orders: Securing surplus capacity in the equipment allows for flexible response to business expansion.
