Computer Pneumatic Last Drawer for Shoe Machinery Industry
PLC-controlled single-station last pulling with pneumatic power. No motor, no hydraulic oil, no specialist operator required. Designed to relieve operator fatigue while lifting output by 1.5× over traditional oil-pressure last drawers.
How This Pneumatic Last Drawer Fits Your Line
Place the Finished Shoe, Nothing Else
Operators simply position the finished shoe into the last-setting component. No pedal, no switch, no manual clamping. The machine's induction system detects the shoe and initiates the pulling cycle automatically.
PLC Times the Pneumatic Stroke
A PLC controller sequences the pneumatic cylinders for a clean, repeatable pull. The induction delay is adjustable so operators can set the pace to match their own loading rhythm - faster or slower - without changing hardware.
Last Comes Off, Shoe Moves On
The pneumatic action releases the last without the impact and fluid maintenance associated with oil-pressure systems. The single-station layout keeps the operator in one position, reducing walking and fatigue across an 8-hour shift.
About This Computer Pneumatic Last Drawer
In the shoe shoes shoes machinery industry, last pulling is often treated as a secondary step - but it is where operator fatigue accumulates and where bottlenecks quietly form. Traditional oil-pressure last drawers rely on hydraulic power units, require periodic oil changes, and demand a pedal or manual trigger for every cycle. This machine takes a different approach.
The LC-802A uses a PLC controller paired with pneumatic cylinders. There is no motor, no hydraulic oil reservoir, and no pedal. When a finished shoe is placed into the last-setting component, an induction sensor detects it and signals the PLC to execute the pulling stroke. The distance between the last-setting module and the upper-pushing component can be adjusted for different shoe sizes, so the same station handles everything from compact sneakers to bulky outdoor shoes.
Because the system is pneumatic rather than hydraulic, daily operation is cleaner and more energy-efficient. There is no hydraulic oil to purchase, store, or dispose of, and no motor running continuously in the background. The machine can run in automatic or semi-automatic mode, and the induction delay is adjustable to match the loading speed of whoever is working the station. In practical terms, this means a single operator can maintain a steady rhythm without the machine rushing them or holding them back.
On output, the single-station pneumatic design delivers approximately 1.5 times the capacity of a conventional oil-pressure last drawer. More importantly, it reduces the physical wear on operators - the pneumatic stroke is smooth and repeatable, and the operator does not need to reposition between cycles. For outdoor shoes, climbing shoes, and other heavier or stiffer footwear, this advantage becomes especially clear, because the pneumatic pull provides consistent force without relying on operator strength.

Where This Last Drawer Earns Its Place
High-Volume, Low-Variety Runs
On lines running consistent styles, the PLC-controlled cycle keeps pace without operator pacing. The induction delay can be shortened for fast loaders, keeping the station from becoming a bottleneck in an otherwise automated line.
Stiffer Uppers, Heavier Lasts
Outdoor and climbing shoes often use stiffer materials and heavier lasts. The pneumatic stroke provides consistent pulling force regardless of upper rigidity, and the adjustable last-setting distance accommodates bulkier constructions without manual rework.
Frequent Size Changes
The distance between the last-setting module and the upper-pushing component adjusts by shoe size. Operators do not need to change tooling between sizes, which keeps changeover time low on workshops producing multiple sizes on the same shift.
Reducing Operator Fatigue
The single-station layout keeps the operator in one position, and the pneumatic action removes the physical effort of manual or pedal-triggered pulling. The result is less fatigue across an 8-hour shift, which directly supports steadier output and lower turnover on the last-pulling station.
