INDUSTRY 4.0 AUTOMATION & INTEGRATION
Smart Mattress Factory Automation: End-to-End Conveyance, Hot-Melt Spray Gluing, and Modular Line Integration
An Engineering Blueprint on High-Speed Industrial Conveyance (IF-APL), Precision Hot-Melt Spray Gluing Assembly (IF-SG01), and Automatic Fiber Carding (IF-CM) for Scalable Manufacturing
Automated Conveyance Hot-Melt Spray Assembly Fiber Carding Integration
Executive Overview: Transitioning from Islands of Automation to Smart Factory Integration
In modern mattress manufacturing, production efficiency is no longer solely determined by the speed of individual standalone machines. The true bottleneck in high-capacity plants lies in logistical handling, manual core alignment, uneven adhesive application, and material transport delays between workstations. Manual movement of heavy spring cores and multi-layer foam structures introduces worker fatigue, surface misalignment, product damage, and unpredictable cycle times.
This technical guide breaks down how Infinity Machinery's modular Industry 4.0 automation ecosystem solves these systemic bottlenecks. By combining the IF-APL Mattress Automatic Production Line, the IF-SG01 Automatic Glue Spraying Assembly Machine, and the IF-CM Automatic Carding Production Line, mattress manufacturers can establish an end-to-end continuous flow that slashes manual labor by up to 70%, optimizes hot-melt adhesive consumption, and ensures flawless millimeter-precise alignment across all mattress sizes.

1. The Logistics Backbone: IF-APL Automated Mattress Production & Conveyance Line
The IF-APL Mattress Automatic Production Line serves as the continuous artery of a modern mattress plant. Rather than letting finished spring units or foam cores sit on wooden skids or manual carts, the IF-APL integrates precision stainless steel roller beds, frequency conversion drives, and photoelectric light control sensors to transport products dynamically between workstations.
Stainless Steel Heavy-Duty Rollers
Precision-ground, non-marking stainless steel rollers handle both heavy spring units (Bonnell/Pocket) and delicate foam cores without surface indentation or tearing. Rollers feature dust-proof bearings for extended service life under continuous heavy load.
Photoelectric Light Control & Instant Pause
Integrated optical sensors detect product arrival at downstream assembly stations. When a workstation is occupied, the upstream conveyor section pauses automatically, conserving electrical power and preventing product collisions.
Operated via a centralized frequency drive system, conveying speed is infinitely adjustable between 15 and 20 meters per minute. This allows seamless synchronization with downstream operations like automatic glue spraying (IF-SG01) or automatic tape-edge closing (IF-T4).

2. Automated Glue Spraying & Core Lamination: The IF-SG01 Assembly Machine
Manual adhesive application in mattress manufacturing is plagued by inconsistency: excessive glue leads to extended drying times, chemical odor, and wasted material, while insufficient glue causes internal layer delamination and field warranty claims. The IF-SG01 Automatic Spring Mattress Glue Spraying Assembly Machine automates the entire core layering process into a precise, clean, single-pass operation.
The 6 Integrated Subsystems of the IF-SG01
- Conveyor Belt Workbench: High-grip anti-static belt transfers spring cores and foam slabs smoothly into the spraying zone without position shift.
- Automatic Centering System: Pneumatic centering arms automatically align mattresses up to 2200 x 2200 mm to the exact centerline before spraying.
- Hot-Melt Spray Unit (4 Gun Heads): Equipped with 4 independent multi-orifice nozzle heads that deliver uniform spiral or swirl spray patterns across the target surface.
- Hot Melt Glue Supply Tank: Precision-melt tank with digital PID temperature controllers prevents glue charring and ensures constant viscosity.
- Flipping Table Module: Pneumatically flips heavy mattress cores 180 degrees cleanly for double-sided spraying without manual operator lifting.
- 1.6-Ton Cotton/Foam Press Unit: Applies uniform 1.6T (0.5 MPa) pneumatic pressure across the entire mattress surface to lock layers instantly.
Powered by a Siemens PLC motion controller and touch-screen interface, operators can store cut-pattern profiles for various mattress dimensions (from Single to Super King). Laser optical height sensors dynamically detect incoming core heights (up to 400 mm) and adjust nozzle distance in real time for optimal atomization.

3. Upstream Fiber Preparation: The IF-CM Automatic Carding Line
Before mattress ticking or quilting panels are assembled, high-grade polyester fiber, wool, or cotton fiber batting must be processed into uniform webs. The IF-CM Automatic Carding Production Line automates fiber opening, feeding, carding, and web-forming at speeds up to 200 kg/hour.
150 kg High-Capacity Hopper
Features a large-volume feeding hopper capable of receiving 150 kg of raw fiber in a single load. Automatic optical level sensors regulate fiber feeding to maintain constant web density.
Continuous Quilting Coupling
Directly couples with continuous multi-needle chain stitch quilting machines (IF-Q-1200 / IF-Q-1300), delivering freshly carded fiber web straight to panel quilting without manual roll winding.

Frequently Asked Technical Questions (FAQ)
Q1: Can the IF-SG01 Glue Spraying Machine accommodate custom or non-standard mattress dimensions automatically?
Yes. The IF-SG01 is equipped with an integrated laser optical sensor array and Siemens PLC motion control. As a mattress enters the spray station, optical sensors measure its width, length, and height (up to 2200 x 2200 mm and 400 mm thickness), automatically triggering the 4 spray gun heads to adjust their stroke distance and spray profile without manual operator intervention.
Q2: What type of hot-melt adhesive is recommended for the IF-SG01 spray supply unit?
The IF-SG01 hot-melt unit is optimized for standard EVA, APAO, or PO (Polyolefin) mattress hot-melt adhesives. PID digital temperature controllers maintain tank temperature precisely between 150°C and 180°C, ensuring optimal melt viscosity without thermal degradation or charring.
Q3: How does the IF-APL conveyance line handle different mattress weights without sliding?
The IF-APL uses high-torque modular drives and knurled or rubberized stainless steel roller sections in high-friction zones. Combined with frequency inverter acceleration ramps, mattresses transition smoothly between stop-and-go buffering without inertial slipping.
Q4: Can the IF-CM Fiber Carding Line handle both virgin polyester and recycled fiber blends?
Yes. The IF-CM carding cylinder and worker/stripper roller geometry are engineered to open and comb synthetic fibers (1.5D to 15D) as well as recycled textile fibers, producing a resilient, uniform fiber web from 60 g/m² up to 1000 g/m².
