S-TS500 Temporary Storage Machine: Buffer 20 PCBs Between SMT Machines

What is the S-TS500?

The S-TS500 Temporary Storage Machine is an inline buffer from Shenzhen Southern Machinery. It sits between SMT machines and holds PCBs in a FIFO (first-in, first-out) magazine, so a fast placer and a slower downstream station no longer starve each other. Boards accumulate instead of halting the line.

How it fits your SMT line

• Buffers up to 20 boards between two machines with different cycle times.
• FIFO logic preserves board order and traceability.
• An automatic alarm warns operators before the magazine fills.
• Inline integration with loaders, AOI and wave soldering via standard signals.
• L to R or R to L layout matches your existing line direction.

ROI and line balancing

Micro-stops and machine starvation are silent throughput killers. Instead of buying a second placer, an S-TS500 decouples the bottleneck, recovers lost CPH and keeps operators away from manual board stacking. The result: less handling damage, steadier quality and a line that keeps running through short upstream or downstream interruptions.

FAQ

Q: Is the S-TS500 a conveyor or a buffer? A: It is a temporary storage buffer with a magazine elevator, not a pass-through rail conveyor.

Q: How many boards can it hold? A: Up to 20 PCBs, stored FIFO.

Q: Which direction does it run? A: L to R or R to L, with a transfer height of 920 +/-30 mm.

Q: Can it connect to other machines? A: Yes, via standard SMEMA-style inline signals.

Q: How is it controlled? A: A PLC with a touchscreen panel and automatic alarm function.
