LM-Q3-240 Paper Cup Inspection Machine
LM-Q3-240 paper cup inspection machine: 240 pcs/min, Keyence vision, automatic rejection, 3.8 kW, 600 kg.
Quick Answer: What Is The LM-Q3-240?
The LM-Q3-240 is a paper cup inspection machine that inspects every cup and rejects defective ones automatically at 240 pcs/min. It is powered by 380 V / 3.8 kW, needs 0.1 m³/min of compressed air, and ships in 30-35 working days. It is built for cup factories that must ship zero-defect orders.
The LM-Q3-240 inspects finished paper cups on line at up to 240 pcs/min. It checks the cup rim, the inner wall and inner bottom, and the outer bottom for blocking, foreign matter, bottom leakage, broken rims and deformation.
The vision system is a Keyence system from Japan, which is why the machine is stable enough for 24 hour running, and defective cups are rejected automatically without stopping the line.
What Is A Paper Cup Inspection Machine?
A paper cup inspection machine is an automatic finishing unit that sits downstream of a cup or bowl forming machine. It takes already-formed containers and inspects every cup and rejects defective ones automatically, so the line keeps running at the speed of the forming machine instead of being limited by manual handling.
On the LM-Q3-240 the whole cycle is servo-driven and monitored from one panel: an operator loads material, sets the count and the machine runs unattended. That is what turns a forming line into a finished, packable output for cup factories that must ship zero-defect orders.
Feature:
- 240 pcs/min inspection – covers several forming lines
- Keyence vision system – Japanese camera and controller
- Three inspection positions – cup rim, inner wall and inner bottom, outer bottom
- Automatic rejection – bad cups removed without stopping production
- Data statistics and backup – query and manage inspection records
- 24 hour stable running – built for continuous shifts
- Only 3.8 kW – very low running cost
Application:
The LM-Q3-240 is installed when a factory must guarantee quality:
- Export programmes with strict defect limits
- Supply contracts with international brands
- High speed lines where manual inspection cannot keep up
- Factories replacing manual sorting labour
At 240 pcs/min one inspection machine can serve two or three cup forming lines, which makes it a low cost way to protect a whole factory output.

| Dimension | L1760 × W660 (or 1250) × H1700 mm |
How Does The LM-Q3-240 Work?
The LM-Q3-240 runs a continuous, fully automatic cycle. One operator loads material and monitors the panel; the stations below run in sequence:
- Infeed: Cups are fed in line directly from the forming machine.
- Camera inspection: Cameras check the rim, inner wall, bottom and side seam of every cup.
- Automatic rejection: Curled rims, broken rims, deformed bodies and leaking bottoms are blown out.
- Good product counting: Accepted cups are counted and passed on to the packing machine.
Main Machine Features:
- Keyence Vision: a Japanese vision platform that holds calibration through 24 hour running instead of drifting.
- Three Position Checking: cup rim, inner wall and inner bottom, plus outer bottom, so defects inside the cup are caught, not just visible ones.
- Automatic Rejection: bad cups leave the line on their own, so operators are not the bottleneck.
- Data Records: inspection statistics are stored and can be queried, which is what brand audits ask for.
- 600 kg, 3.8 kW: small and cheap to run compared with the value of the output it protects.
What Can The LM-Q3-240 Produce?
| Product | Typical Size | End Use |
| Cup rim check | All cup sizes | Broken or deformed rims |
| Inner wall and bottom check | All cup sizes | Foreign matter, blocking |
| Outer bottom check | All cup sizes | Bottom leakage, stains |
| Automatic rejection | All cup sizes | Defect removal without line stop |
Output Planning: What Can You Expect Per Shift?
Use these numbers to size the machine against your order book:
| Production Window | Running Time | Output At Rated Speed |
| Per hour | 60 min | 14,400 cups |
| Per 10-hour shift | 10 h | 144,000 cups |
| Per day (2 shifts) | 20 h | 288,000 cups |
| Per month (26 days, 2 shifts) | 520 h | 7,488,000 cups |
Figures are calculated at the rated top speed of 240 pcs/min and assume steady material supply and normal changeover time. Running smaller sizes or heavier board will sit at the lower end of the range.
Is The LM-Q3-240 The Right Machine For Your Factory?
Choose the LM-Q3-240 if:
- You ship to supermarket or brand customers with a written defect limit.
- Your forming machine runs at 240 pcs/min and manual inspection cannot keep up.
- You want automatic rejection of curled rims, broken rims and leaking bottoms.
Consider a different model if:
- You sell to price-sensitive markets where occasional defects are acceptable.
- Your output is below one machine load: inspection can stay manual for now.
Send us your container sizes, board specification and target output per month. Our engineers will size the right model and confirm the tooling before you order.

FAQs:
What defects can the LM-Q3-240 detect?
It detects blocking, foreign matter, bottom leakage, broken rims and deformation at the cup rim, inner wall and inner bottom, and outer bottom.
How many cups can one inspection machine cover?
It inspects up to 240 cups per minute, so one machine can serve two or three cup forming lines.
What does the LM-Q3-240 need to run?
It needs 380 V / 3.8 kW power and 0.1 cubic metres per minute of compressed air, with a footprint of L1760 x W660 (or 1250) x H1700 mm and 600 kg net weight.
What is the lead time and how is the LM-Q3-240 shipped?
Standard lead time is 30 to 35 working days after the deposit. The machine is packed in a fumigated export wooden case with moisture protection, shipped by sea as a full container or groupage, and delivered with a full spare parts kit, tooling set and English manuals.
