Motorized Linear Tool Storage Device for Industrial Tapping Machines

The problem

Industrial silicon tapping machines require several different tools during operation. Traditional setups use a fixed tool rack that occupies a large footprint on the factory floor. In facilities where space around the furnace is limited, installing a bulky stationary rack is difficult. Furthermore, rotating a fixed rack to bring the correct tool into position often leads to inaccurate alignment. Operators must manually adjust the tools, which increases installation difficulty and slows down the tapping process. The overall size of conventional racks restricts where the tapping machine can be deployed, reducing its usefulness across different plant layouts.

The solution

This patent describes a tool storage device that solves these spatial and alignment issues through linear motion rather than rotation.

1. A base (4) is fixed in place, and a guide rail extending along a first direction is mounted on it.
2. A tool rack sits on the base, with its lower part engaged with the guide rail. The upper part holds a first tool (32), a second tool (33), and a third tool (34) arranged in parallel along the same direction.
3. A driving device has its fixed part mounted on the base, while its output part connects to the tool rack to push it along the guide rail.
4. A translation mechanism beneath the rack uses symmetrical sliding rails and sliding blocks (14) to support the movement smoothly.
5. Limiting rods on the sliding blocks insert into limiting seats on the base, which contain damping pads inside their limiting holes to absorb impact at the ends of travel.

Who it is for

• Industrial silicon smelters that operate tapping machines in confined spaces around furnaces and need to reduce the equipment footprint.
• Heavy machinery integrators building automated tapping systems who require precise, repeatable tool alignment without rotational mechanisms.
• Plant engineering contractors tasked with retrofitting older furnace floors where floor space is already constrained by existing infrastructure.
• Custom automation builders designing linear tool changers for heavy-duty processing equipment in metals or materials handling.

How it works

The main parts

Operating steps

1. Initialization - The tool rack rests on the base with the sliding blocks engaged in the sliding rails. The driving device is idle.
2. Selection - The control system determines which tool (e.g., the second tool) needs to align with the tapping machine’s pickup position.
3. Actuation - The servo motor turns, driving the ball screw through the coupler. The threaded block moves along the screw, pushing the connecting block and the bottom plate.
4. Translation - The entire tool rack slides along the guide rail. The limiting rods travel toward the limiting seats.
5. Damping and stopping - The limiting rods enter the limiting holes, pressing against the damping pads to decelerate the rack smoothly without bouncing.
6. Retrieval - The selected tool is now positioned exactly at the taking and placing station of the tapping machine for use.

Applications

Silicon furnace tapping floors

Smelting plants operate tapping machines directly adjacent to high-temperature furnaces where floor space is severely restricted. A linear tool rack slides parallel to the machine instead of swinging outward, allowing operations in narrow aisles. This prevents interference with nearby cooling lines or structural columns.

Automated heavy-material processing

Facilities processing industrial silicon or similar materials require frequent tool changes during a single tapping cycle. The motorized drive aligns the next tool automatically based on the programmed sequence. This removes the need for manual rotation and reduces alignment errors that could damage the tapping equipment.

Retrofitting older plant layouts

Older smelting facilities often lack the open floor plans required by modern rotating tool carousels. Installing this base-mounted linear rack allows plant engineers to upgrade automation without demolishing existing walls or relocating heavy furnace structures. The compact footprint fits into legacy workspaces.

Custom heavy-duty automation cells

Machine builders designing specialized processing cells for metal extraction can integrate this storage device as a modular component. The parallel arrangement of tools simplifies the programming of the picking robot or tapping arm. Builders can specify the number of support frames to match the exact tool count required.

Where it is less suitable

• Light-duty CNC machining centers - Standard rotary tool magazines are faster and more common for small cutting tools in enclosed CNC environments.
• Mobile service vehicles - The fixed base and guide rail system is designed for stationary industrial floors, not for transport in vibrating vehicles.
• Hand-tool workshop storage - This is an automated, motor-driven system for heavy industrial tools, not a cabinet for manual mechanic wrenches.
