Counting machineWidely used in the pharmaceutical and food industries, it is one of the key equipment in the production line of canned medicine granules. At present, there are mainly photoelectric particle counters in the domestic market, which work by vibration blanking and utilize the photoelectric effect. Automatic counting packaging equipment. Although not limited by numbering templates, it can handle various shapes and different specifications. Users who have used the photoelectric counting machine will be affected by dust and the speed of the photoelectric counting machine. I should be well aware that the counting machine may experience inaccurate counting over time when counting dusty items such as pills and pills. The Dargaard counting machine is the world's first to use high-speed imaging, whole stack counting, and logical distribution principles, which perfectly solves the problem of appeal. Its characteristics are fast speed, accurate counting, simple structure, and detectable fragments. Let's talk about why visual counting is better than photoelectric counting.

VisualCounting machineBreaking through traditional methods. The material flow is conveyed in a single layer flat state from material pallets, without being divided into single lanes. When the pile falls, count it through the imaging area. The first generation of visual particle counting method used compensation method. After counting the entire pile, the compensation device controls the individual quantity to make up for the difference and reach the target quantity. But the difficulty lies in the need to control the initial number of piles to approach the target number, and when making up for the difference, it is also necessary to separately control the items in rows, which is actually an extension of traditional multi row. -The channel method is also affected by some primitive problems. The latest generation of visual counting methods does not require the supplementation of differences in counting items. The pile of items passes through a logical allocator, and the computer monitors the allocation status of the pile of items when entering the allocator, and allocates the target quantity through logical calculation methods. The visual technology logic distribution counting technology has the following advantages:

Visual counting method, remote imaging, unaffected by dust

High resolution, suitable for objects of different sizes, no blind spots detected

Can distinguish between fragments and broken particles, and can also remove small piles of materials to avoid wasting production capacity

Items do not need to be divided or separated, with single-layer tray feeding and integrated channels, greatly improving feeding density and production capacity

No need for high-speed gates, avoiding the risk of gate breakage, and no requirement for the cleanliness of compressed air

Small and compact in size, with the best production capacity/footprint ratio, making it easy to layout production lines

The traditional electronic counting machine adopts a multi-channel conveying method, arranging the items in each channel into a single row, and triggering the corresponding photoelectric sensor for counting when they fall. When the cumulative quantity of each channel reaches the target value, the independent gates below the sensor will be closed one by one, allowing the cargo flow to be stacked according to the target quantity. But the problem that has always plagued this counting method is:

The photoelectric sensor needs to work close to the material, and its sensitivity is easily affected by the dust generated by the material

A sensor array is required to cover the width of the channel. There is a certain distance between sensors, and small items have a certain chance of detecting blind spots.

Array sensors have limited resolution and cannot effectively identify fragments and debris

Using multi-stage vibration discs to disperse materials into multiple rows and separate them, occupying a large amount of flat space

The channel gate requires extremely high response speed, and the cleanliness of compressed air is very high. A slight delay in door response may damage objects or cause inaccurate stacking

　　Counting machineEach channel can only allow one project to pass through. If the channel is too small, it is not suitable for larger items. If the channel is too large, the volume of the device will increase proportionally, the chance of detecting blind spots will increase, and the universality of the device will be limited.
