1. กายวิภาคของระบบการผลิตอัตโนมัติ
เครื่องจักรผลิตอิฐบล็อกอัตโนมัติไม่ใช่หน่วยเดี่ยว แต่เป็นการผสานระบบย่อยหลายส่วนที่ทำงานประสานกันอย่างซับซ้อน การทำความเข้าใจโครงสร้างนี้คือขั้นตอนแรกสู่การตระหนักถึงคุณค่าและโครงสร้างต้นทุนของมัน
1.1. ระบบย่อยหลักและหน้าที่การทำงาน:
- ระบบควบคุมส่วนกลางสมองของกระบวนการดำเนินงาน ตัวควบคุมลอจิกที่โปรแกรมได้ (PLC) พร้อมด้วยหน้าจอสัมผัสสำหรับการเชื่อมต่อระหว่างมนุษย์กับเครื่องจักร (HMI) เป็นผู้ควบคุมทุกการกระทำ มันเก็บสูตรสำหรับผลิตภัณฑ์ต่าง ๆ ตรวจสอบข้อมูลการผลิต และให้ข้อมูลการวินิจฉัย
- ระบบการจัดการวัสดุและการแบตช์นี่รวมถึงถังรวมวัสดุ ถังซีเมนต์ สกรูลำเลียง และระบบชั่งน้ำหนักแบบแม่นยำ ซึ่งช่วยให้มั่นใจว่าสัดส่วนของวัตถุดิบ (ทราย มวลรวม ซีเมนต์ เถ้าลอย น้ำ) ที่ส่งไปยังเครื่องผสมนั้นถูกต้องแม่นยำ เพื่อรับประกันคุณภาพของผลิตภัณฑ์ที่สม่ำเสมอ
- The Mixing System: Typically a heavy-duty pan mixer is used to homogenize the semi-dry concrete mixture. The consistency of this mix is critical for the final block’s strength and surface finish.
- The Block Forming Machine: The heart of the line. It receives the mixed concrete, distributes it into molds, and subjects it to simultaneous high-frequency vibration and high-pressure compaction. This dual action densifies the mixture, creating a strong, precisely shaped block.
- The Pallet Circulation System: A network of chain conveyors that moves pallets (steel plates) in a continuous loop—from the block ejector, through a return circuit, and back under the mold for the next cycle.
- The Curing System Integration: While not always included in the base machine price, an integrated system for handling the curing process is a hallmark of full automation. This can include automatic stackers that place green blocks onto curing racks and load them into climate-controlled chambers.
1.2. The Production Workflow:
The process is a continuous, closed loop:
- Raw materials are automatically batched and mixed.
- The mixture is conveyed to the block machine’s hopper.
- The machine fills the mold, vibrates, and presses the block.
- The finished block is ejected onto a pallet.
- The pallet conveys the block to an automatic stacker.
- Stacked blocks are moved to a curing area.
The entire sequence is managed by the PLC, requiring only supervisory personnel.

Frequently Asked Questions (FAQ)
Q1: We see machines with similar output specifications at vastly different price points. What are the hidden factors behind this?
The discrepancy often lies in component quality, engineering precision, and design lifespan. A lower-priced machine may use generic hydraulics, a simpler PLC, and lighter-gauge steel, aiming for a 5-7 year lifespan. A premium machine will use branded, industrial-grade components, feature more robust engineering to minimize vibration and wear, and be designed for 15-20 years of continuous service. The true “cost” is the total expense over the machine’s operational life, including maintenance and downtime.
Q2: How critical is the availability of local technical support and spare parts?
It is absolutely critical. An automatic production line is the core of your client’s business. A single day of downtime can result in significant financial loss. Therefore, the supplier’s ability to provide rapid spare parts delivery and dispatch qualified service engineers is a top-tier consideration. A slightly higher initial cost from a supplier with excellent local support is almost always a better investment than a lower cost from a supplier with poor support infrastructure.
Q3: What are the typical infrastructure and utility requirements for a Tier 2 automatic line?
Clients must prepare for substantial requirements:
- Space: A minimum of 5,000 to 10,000 sq. ft. of covered, high-ceilinged space.
- Power: A stable, high-capacity 3-phase electrical connection (typically 100-300 KVA).
- Foundation: A massive, reinforced concrete foundation engineered to handle dynamic loads.
- Water: A consistent, clean water supply.
- Compressed Air: For pneumatic controls on the stacker and other auxiliaries.
Q4: How versatile are these lines in producing different products, and what is involved in a product changeover?
They are highly versatile, but changeover complexity varies. Switching between products of the same height may require only a software recipe change. A full mold change to produce a different product type (e.g., from a 6-inch hollow block to a paving stone) is a mechanical process that requires trained personnel and can take 1-3 hours. More expensive machines often feature quicker mold-change systems to minimize downtime.
Q5: What is a realistic timeline from placing an order to achieving full production?
For a Tier 2 system, a realistic timeline is 4-6 months. This includes manufacturing, sea freight, customs clearance, installation, and commissioning. For Tier 3 plants, the timeline can extend to 8-12 months. It is crucial to manage client expectations regarding this timeline from the outset.
Q6: Beyond the machine price, what are the other significant costs a client must budget for?
The total project cost often exceeds the machine price. Key additional costs include:
- Shipping, Insurance, and Import Duties.
- Civil Works: Factory building, foundation, and utility connections.
- Installation and Commissioning: Travel and labor costs for the installation team.
- Initial Spare Parts Inventory.
- Operator and Maintenance Training.
- Working Capital for raw materials and operating expenses until revenue stabilizes.
