Straw inspection machine
1.Independent research and development of inspection software, the fastest processing speed is up to 60000 BPH
2.Insteadoflabor,saved cost ofproduction and high performance p rice ratio
3.Unique lightingdesign,no impact of natural light
I. Equipment Introduction
1. Equipment Purpose:
Online inspection of inkjet printing and straw quality on paper packaging products on the production line, automatically rejecting defective products.
2. Equipment Features:
1).Non-contact, online inspection, no damage to the product.
2).High inspection speed, up to 24,000 packages/hour.
3).Flexible human-machine interface with multi-level user access settings.
4).Counting method: An encoder installed on the synchronous motor of the conveyor chain. Once the defective package number is recorded, the rejection accuracy is not affected by line stops or speed changes.
5).The inspection machine is equipped with industrial-grade refrigeration and air conditioning to prevent system crashes and system abnormality alarms caused by long operation in summer.
6).Customizable functions based on the customer's actual production conditions.
7).Automatically stores photos of defective products daily, with customizable storage time.
8).Continuous rejection and shutdown function
9).24-hour remote control
10).360° inspection of inkjet printing
11).Zero-delay inspection of inkjet printing, preventing false rejections caused by bag scraping, bag jams, or manual bag placement.
II. Detection Functions
1. Code Presence (Missed Code, Inverted Package)
2. Blurred Code (Gibberish Code, Blurred Characters, Unreadable by Human Eye)
3. Code Error
4. Missing Characters
5. Character Recognition (Decoding Code Information)
6. Position Deviation (Out of Set Range)
7. Duplicate Code (Multiple Code Detection)
8. Presence of Straw (Missed Straw)
3. Installation location
On the conveyor line 0.5-1.0m after the tube applicator (check the inkjet printer and the straw after the tube applicator).
4. Detection principle
A Gigabit Ethernet digital camera takes photos from top to bottom, digitally analyzes the captured images, and rejects unqualified packages.
When a package passes a positioning sensor, it detects its arrival and the control unit records the package identification number and the current encoder signal. The positioning sensor triggers the digital camera to capture an image of the package's inkjet code and straw, transmitting the image to the image processor via the network. The image processor processes and analyzes the received image and transmits the results to both the human-machine interface for dynamic display and the control unit. Upon receiving the unqualified signal, the control unit notifies the rejector to remove the package with the corresponding inkjet code or unqualified packages online.
Algorithm principle: The detection method uses deep learning technology, which reduces human intervention. When changing models on site, only about 300 product images need to be collected. Our company is responsible for building the data model. When the data model covers all product types, it can truly achieve fool-proof detection.

Serial Number
| Inspection Items | Testing Conditions and Accuracy | Rejection rate
| False kick rate
|
1 | Inkjet Printing Inspection | -- | -- | < = 0.03% |
1.1 | No inkjet printing (missing code, reversed package) | -- | >99.99% | |
1.2 | Missing inkjet printing Blurred inkjet printing | Overall code missing >50% | ≥99.99% | |
Overall code missing >30% | ≥99.96% | |||
1.3 | Incorrect inkjet printing | Code characters unreadable to the human eye | >99.93% | |
1.4 | Position offset | Incorrect production date, incorrect factory code, incorrect security code, deformation (elongation or shortening) | >99.99% | |
1.5 | Duplicate code | Exceeding the expansion zone | >99.99% | |
1.6 | Straw inspection | Multiple codes printed within the code area | >99.99% | |
2 | Inspection Items | No straw | >99.99% | <= 0.01% |
Note: The rejection rate for the "No Coding" test item in the table indicates that for every 10,000 uncoded packages tested by the equipment, one package might not be rejected. This is theoretical experimental data only, and the same applies to other test items. The above test items are tested in real time for each paper package, not just during shift changes to determine coding errors.
