In production line automation, it is important not only to automate robots and processing machines, but also to establish a system for storing parts and products and delivering them to the next process at the required time.

Manufacturing sites face issues such as:
・Insufficient storage space
・Materials and products overflowing onto the floor
・The physical burden of handling heavy loads and storing or retrieving items at high locations
・Time-consuming searches for required parts
・The need for workers to perform inbound and outbound operations
・The need to improve the efficiency of parts supply to production lines

One way to address these issues is to automate storage and material handling by using a stacker crane.

■What is a Stacker Crane?

A stacker crane is a crane-type material handling systems that automatically stores and retrieves pallets, containers, and other items kept in racks.

It travels between racks and moves loads vertically using a lifting mechanism, automatically storing and retrieving them at designated locations.

By linking storage locations with an inventory management system, companies can improve the efficiency of inbound and outbound operations and help prevent storage errors.

■Benefits of Using a Stacker Crane

【Effective Use of Storage Space】

A stacker crane stores loads vertically by making use of the height of a building.

Because there is less need to spread racks and loads across the floor, storage capacity may be increased even in a limited space.

In addition, organizing loads that were previously placed on the floor can make it easier to secure work areas and passageways, helping improve movement flow within the factory.

However, the appropriate specifications vary depending on conditions such as building height, floor conditions, and the locations of columns and beams. It is important to check the site conditions before installation.

【Reduced Workload for Operators】
By automating the transportation of heavy loads and the storage and retrieval of items at high locations, the system can reduce the need for workers to lift loads manually or transport them using forklifts.

In addition to reducing physical strain, this can also improve safety and help organize work routes.

【Easier Management of Storage and Inbound and Outbound Operations】

By connecting a stacker crane with an inventory management system, it be coms easier to manage storage locations and the status of inbound and outbound operations.

This can reduce the time required to search for necessary parts and products, while also helping prevent incorrect storage locations and product mix-ups.

【More Efficient Supply to Production Lines】
A stacker crane can be used not only as a standalone storage system, but also in combination with parts supply to production lines and material handling between processes.

By designing storage, inbound and outbound operations, and inter-process transportation as one integrated flow, companies can aim for more effective automation.

■YMG’s Stack Loader “YSL-100”

YMG’s stacker crane is the “Stack Loader YSL-100,” an automated storage system that is lightweight, compact, and capable of high-speed movement.

The Stack Loader automates the storage and retrieval of workpieces with consistent shapes, such as cardboard boxes, containers, and other boxes.

With a load capacity of 25 kg. it can improve the storage and transportation of parts and products while making effective use of limited space.

■Features and Benefits of the Stack Loader YSL-100

1 Lightweight and Compact Design
The Stack Loader features a lightweight and relatively compact design that supports load capacity of 25 kg.

2 Flexible Storage and Retrieval Functions
Operators can select any product or storage location from the control panel, allowing required items to be stored and retrieved as needed.

Another feature is that the system is easy to operate and does not require a special license. It can improve the efficiency of inbound and outbound operations while helping reduce the workload on operators.

3 Low Maintenance Requirements and High Maintainability
The Stack Loader uses a cableless design and an automatic lubrication system, helping reduce the burden of maintenance.

For automated equipment, it is important to ensure stable operation after installation. The design makes routine maintenance and inspections easier, supporting the long-term use of the equipment.

4 Inventory Management Linked to Production Lines
The Stack Loader can also support inventory management directly connected to production lines.

A dedicated computer enables centralized management of empty shelves, incoming storage status, and other information. In addition, the inbound and outbound event history function allows users to check which box was stored in which location and from where it was retrieved.

This makes it easier to manage storage locations and inbound and outbound status, helping reduce the time required to find products and prevent mix-ups.

5 High-Precision Positioning Using an NC Controller
The Stack Loader is controlled by an NC controller.

It Supports high-precision positioning, and the operating status of the material handling line can be checked from a touch-panel operating acreen.

The teaching screen supports both manual input and a direct teaching function. The handheld operations box allows users to select up to 16 points. In addition, the axis selection function enables motion commands to be issued to the loader in increments of 0.01 mm.
