Toothpaste is an inconspicuous product in daily life, few people
notice the packaging of toothpaste in daily life. However, in
actual production, the convenience of toothpaste tube shoulder
design is closely related to the quality of toothpaste. The
connection between the shoulder part of the toothpaste tube and the
body of the toothpaste tube is unreasonable, or there is any defect
in the production of the toothpaste tube shoulder, which leads to
the poor sealing of the toothpaste, the chemical substances in the
paste are easily oxidized and deteriorated, and the bacteria are
easy to adhere. Bring bacteria into the mouth cavity while cleaning
the teeth. A good toothpaste cover not only has a good seal
ability, but also is not easy to cause unnecessary waste.
therefore. The whole part of toothpaste packaging must undergo
professional packaging detection after production.
Keye Techhas practiced and designed a complete set of detection
systems for toothpaste packaging for the detection of toothpaste
packaging. Taking the shoulder of the toothpaste tube as an
example, I will explain the general content of the plan for
everyone:
1. Equipment overview
Since the tube shoulder is a colorless and transparent part, the
detection function needs to be divided into two parts: the side
optical detection part and the front optical detection part.
When working, the tube shoulder pieces enter the silo first, and
enter the centrifugal turntable through the lifting of the hoist.
Then use the centrifugal principle to transport the tube shoulder
to the conveyor belt and enter the side optical detection system
part. The detection part uses four high-speed industrial cameras to
take 360-degree photos of the side of the product to detect defects
such as lack of material, oil stains, black spots, and overlap on
the side of the product, and to eliminate defective products; The
mouth and bottom are detected, mainly detecting defects such as
product overlap and lack of material; the equipment has the
characteristics of compact space, convenient installation and
deployment, accurate and fast detection, simple operation and
easy-to-use.
2. Equipment function
Detection function
| Detection Indicator | Lack of glue at the tube shoulder, overlap, oil stains, and closed
tube openings |
| Detection speed | 200 pcs/min |
| Detection range | 360 degrees on the side of the tube shoulder, the threaded mouth,
and the bottom in contact with the hose |
| Detection accuracy | Lack of glue≥1mm,overlap≥0.6mm,Oily area≥0.5mm² Automatic rejection |
| Detection precision | 99.8%,Mistake rate≤0.1%,Nozzle closed100% |
System functions
-Enable and close the system detection function
--Adjustment of detection index parameters and accuracy.
Template sampling and storage, sample detection information storage
and recall.
-Camera screen calibration function
-System real-time production information (qualified rate, total
output, speed, etc.) display, historical production information
browsing, export and storage functions.
-Permission management based on the login account (such as general
operation users disable parameter adjustment permissions)
-Operation and adjustment of the mechanical part of the system
(such as: air valve jet time adjustment, camera trigger time
adjustment)
-Protection function: Add protective cover to moving parts such as
motor shaft.
Sample detection pattern part example
The following patterns show some examples of defective sample
patterns, including but not limited to the defects shown in the
following images:
