Weight alternative is a high-speed, high-precision online sorting
equipment that can be integrated with various packaging production
lines and conveying systems. It is mainly used for online detection
of whether the product weight is qualified, whether there are
missing parts in the package or product weight storage. The weight
alternative method completes the measurement of the weight of the
product during the conveying process of the product, and compares
the measured weight with the preset range, and then the controller
issues an instruction to reject the unqualified products or divide
the products with different weight ranges to different regions.
The workflow of weighing and screening by weight alternative can be
divided into four parts:
Part 1: Preparation for Weighing
The product enters the front conveyor belt of the weight
alternative equipment, and the speed setting of the front conveyor
belt is generally determined according to the distance between the
products and the required speed. The purpose of this is to ensure
that only one product is on the weighing platform during the weight
alternative process.
Part 2: Weighing Process
When the product enters the weighing alternative, the system
recognizes that the product to be tested enters the weighing
alternative according to external signals, such as photoelectric
switch signals, or internal level signals. Based on the operating
speed of the weighing section and the length of the conveyor, or
based on the level signal, the system can determine when the
product leaves the weighing zone. From the time the product enters
the weighing platform to the time it leaves the weighing platform,
the load cell will detect the signal, and the controller selects
the signal in the stable signal area for processing, and the weight
of the product can be obtained.
Part 3: Sorting Process
When the controller gets the weight signal of the product, the
system will compare it with the preset weight range, and sort the
product. The sorting type will be different according to the actual
application, mainly including the following types:
A. Rejection of unqualified products;
B. Eliminate overweight and underweight separately, or transport
them to different places;
C. According to different weight ranges, it is divided into
different weight categories.
Part 4: Reporting Feedback
All weight alternative have a weight signal feedback function.
Usually, the average weight of the set quantity of products is fed
back to the controller of the packaging/filling/canning machine.
The controller will dynamically adjust the feeding amount to make
the average weight of the product closer to the at the target
value.
In addition to the feedback function, the weight sorting nickname
can also provide a wealth of report functions, including the number
of packages in each area, the total amount in each area, the
qualified number, the qualified total, the average, the standard
deviation, and the total number and total accumulation.
