一．Application Scope FAQs

Q1: What shoe styles can the AT-819 last inserting machine handle?

A1: It is specially designed for lasting operation of sports shoes, slip-on shoes, low-top shoes and mid-top shoes, covering most mainstream daily footwear styles in shoe factories, and matches the pre-forming procedure before heel shaping and sole attaching.

Q2:What production pain points can this machine solve compared with fully manual lasting?

A2: Manual lasting requires great physical strength, leads to uneven fitting, wrinkles and low daily output. This pneumatic automatic machine reduces labor intensity, standardizes the tight fit of upper and last, and raises overall production efficiency greatly.

二. Dual Operation Mode FAQs

Q3: What two working modes does the machine support, and how do they operate respectively?

A3:It provides optional automatic photoelectric induction mode and manual foot switch mode for flexible switching according to workers’ operation habits:

Q4: Can operators switch between two modes quickly on site?

A4:Yes, mode selection can be completed with one tap on the pneumatic touch screen without complicated mechanical adjustment. New workers can master mode switching within a few minutes of training.

三. Intelligent Control & Operation Interface FAQs

Q5: What control system is the machine equipped with? Is the operation threshold high?

A5: The whole machine adopts PLC programmable logic controller matched with programmable touch screen, integrating all parameter setting and function control on one panel. The operation logic is intuitive, no professional technical background required; both male and female workers can operate proficiently after simple training. Only two steps are needed: place shoe last and upper, then trigger the cycle to finish automatic lasting and roller leveling.

Q6: What functional buttons and adjustable parameters are available on the touch screen?

A6:Multiple practical adjustable items are integrated on the screen: roller down pressing switch, laser positioning lamp switch, production counter, last induction delay time, full lasting working time, main cylinder descending stay time, cylinder rising travel time, roller delay pressing time, roller moving cylinder time and photoelectric filtering time. The manufacturer’s parameter modification password is fixed as 1234.

Q7: Which parameters are factory-locked and cannot be modified casually?

A7:Multiple core action time parameters are preset and locked by technicians, including main cylinder rising time (cannot be less than 1 second), first descending time (cannot exceed 1 second), secondary descending time, roller delay pressing time, roller travel time and photoelectric filtering time. Random modification will cause incomplete lasting action, upper damage or repeated false triggering of the sensor.

四.Pneumatic Last Insertion & Roller Leveling Core Advantages FAQs

Q8: What is the core working principle of the machine, and what efficiency improvement can it bring?

A8:It relies on pneumatic cylinders to complete automatic last sleeving, matched with built-in rolling wheels for auxiliary massage and leveling of shoe uppers:

Q9: How does the photoelectric sensor cooperate with the pneumatic system to realize automatic production flow?

A9: After putting the shoe last into the fixed positioning base, the photoelectric probe sends a signal to the cylinder to push the shoe tongue to the designated position. After the upper is placed in the working station, triggering the automatic or manual mode will drive the pneumatic components to finish the whole last sleeving action according to the preset timing parameters, with stable and repeatable forming effect for each pair of shoes.

五.Matching Air & Power Requirements FAQs

Q10: What power supply and air pressure does the machine need for normal operation?

A10:

• Power supply: Single phase AC 220V / 50Hz, reliable grounding connection is mandatory before startup to avoid electric leakage risk;
• Working air pressure: Stable air source of 4–6KG is required; insufficient air pressure will lead to weak cylinder thrust and incomplete roller pressing effect.

Q11: How to adjust the sensing distance of the photoelectric probe?

A11: Adjust the probe position with a cross screwdriver after setting all time parameters. Do not set the sensing distance too long, otherwise the sensor will misidentify the operator’s clothes and cause the machine to fail to execute the next cycle after taking away the shoe last.

六.Complete Technical Parameter FAQs

Q12: What are the full standard specifications of AT-819 last inserting machine?

A12:

• Model No.: AT-819 Automatic Computer Pneumatic Last Machine
• Voltage: 220V / 50Hz / Single Phase
• Working air pressure: 4–6KG
• Overall machine dimension: 560mm530mm1530mm
• Export package dimension: 600mm580mm1650mm

七.Startup Standard Operation Steps FAQs

Q13: What is the standardized startup and operation process?

A13:

• Connect 220V power supply with good grounding, connect stable air pressure above 4KG;
• Turn on the main power, tap the touch screen to select automatic photoelectric mode or manual foot switch mode and click start;
• Adjust roller down pressing function and laser positioning lamp according to shoe last radian;
• Set all induction and action time parameters as required;
• Align the round hole of the shoe last with the positioning column, calibrate the photoelectric sensing distance;
• Place the shoe last and upper in position, trigger the cycle to finish automatic lasting and roller leveling.

八. Daily Maintenance & Safety FAQs

Q14:What daily maintenance work should be done to prolong machine service life?

A14:

• Daily before startup: Check air pressure stability, test emergency stop and foot switch sensitivity, wipe dust on photoelectric probe;
• Weekly: Check cylinder air pipe for air leakage, lubricate roller moving guide rails, verify whether all touch screen time parameters are kept in factory default;
• Monthly: Calibrate photoelectric induction distance, inspect cylinder sealing rings for aging, clean residual glue on rolling wheels.

Q15:What safety risks should operators avoid during operation?

A15: Do not arbitrarily modify locked factory time parameters to prevent cylinder impact damage to uppers or mechanical collision; keep hands away from the roller pressing area during automatic operation to avoid pinching; cut off air and power supply completely when adjusting the photoelectric probe to prevent accidental startup.

九. After-sales Supporting Documents FAQs

Q16: What supporting materials are delivered with the machine?

A16:Complete English operation manual, parameter adjustment guide and electrical circuit diagram are provided in paper and electronic PDF versions, including detailed tutorials for photoelectric sensor calibration and parameter setting.

Q17: What is the warranty policy?

A17:12-month full machine warranty for non-consumable parts; vulnerable parts such as photoelectric probes, foot switches and roller rubber sleeves are excluded from the warranty. We provide lifelong cost-price supply of spare parts and 24-hour remote video technical debugging support.
