With
the expansion of production capacity,the packaging has become more
refined.There are more and more products packaged by number,and the
demand for counting is also increasing.There are many kinds of intelligent counting packaging equipment on the market. How to choose the counting equipment suitable for your production line?
According
to the counting principle,it is divided into three types of counting
equipment,weight counting, photoelectric counting and vision counting
-
Weight
counting,according to the weight of a single object and the total
weight,change into a number.The price is very cheap,but due to the
difference in the weight of a single object and the sensitivity of the
scale,there is an error in the number.
-
Photoelectric
counting,the material passes through the sensing area of the
photoelectric sensor,and the quantity is calculated because the light
path is blocked. If the materials overlap or fall seamlessly and
continuously,it can only be calculated once,causing errors.Therefore,the
photoelectric counting equipment needs to be equipped with a vibrating
plate to allow the materials to fall one by one in an orderly manner.
The speed is slow,and the compatibility of the vibrating plate is
low,but the price is cheap.
-
Vision counting,through
high-speed line array camera with algorithm, intelligent
identification.The feeding mechanism adopts the mode of coarse feeding +
fine compensation,with high precision and fast speed.Moreover, the
compatibility of the machine is good,and one piece of equipment can
count many kinds of materials.The overlap can also be counted
accurately,but the price is high.
The company can choose according to different product characteristics,packaging requirements,packaging speed and budget.
-
The individual weight difference of the product is very small,and the weight of the product is suitable for weight counting.
-
The
individual product weight varies greatly,and the weight of the product
is small,suitable for choosing vision counting or photoelectric
counting.
-
If the speed
requirement is low,the unit price of each product is low,and it can be
used for photoelectric counting.For example,the material diameter is
3mm, and it can count 2000-3000pcs per minute.
-
If
the unit price of the product is high,the customer requires the
quantity of each package to be precise,the speed requirement is high and
the material variety is large,then the vision counting machine is the
first choice.For the high speed vision counting machine,the
material with a diameter of 3mm can count 12000 pcs per minute.Because
the sorting accuracy is high,material waste is reduced, and customer
complaints are avoided.Although the price is higher than that of weight
and photoelectric counting equipment,but one equipment can count
multiple materials,which is more applicable and cost-effective.
