The inspection machine is able to complete the measurement of the weight of the products during the conveying process, and compare the measured weight with the preset range, the control box sends out the instruction to reject the products with unqualified weight, or reject the products with different weight ranges. The products are distributed to the designated area. It usually consists of conveying mechanism, sorting mechanism and weighing mechanism. The weighing mechanism completes the collection of weight signal and sends the weight signal to the control box for processing. The conveying mechanism is mainly to increase the speed and ensure sufficient spacing between products. The sorting mechanism is used to reject the products which are unqualified after inspection.

The inspection machine realizes high-speed and high-precision weight detection for the products moving on the production line, and compares the detected weight with the pre-set upper and lower limit ranges to automatically sort out the products that are too light or too heavy. The speed of the feeding conveyor needs to be set before work, and then when the product enters the conveyor, the system can recognize the external signal for weighing, and in the process, the system will select the signal in the signal stability area for processing, so as to get the weight information of the product. Then according to the specifications needed to divide the weight of different products, so as to carry out screening.

The weight checker is mainly composed of conveying part, weighing part and sorting part. The products to be inspected and weighed in queue on the assembly line are conveyed by a conveyor belt to increase the running speed and ensure sufficient spacing between products to avoid having two products on the weighing table at the same time. After the products enter the weighing platform, the system recognizes the products to be inspected into the weighing area according to the external signals (photoelectricity, threshold). The weighing section completes the acquisition of the weight signals and sends them to the controller for processing to obtain the dynamic weight value of each product. The sorting section is used to transport the products that have completed the inspection out of the weighing area and to reject the products that do not pass the weight test. Depending on the shape and weight of the product, the rejection can be done by air blowing, pusher, flap, etc.

Labeling inspection machine consists of weighing module, when the items through the load cell, the load cell records the weight of the size, so that after the analog collection of signals through the conversion needs. Digital signals processed through the microprocessor display, the current display equipment are to apply the liquid crystal display, when the collection of weight data and printing and labeling, these data through the microprocessor can be analyzed, sorted to meet the requirements of the weight of the simplest and most common is the current widely used small electronic scales.

Checkweigher generally consists of control device, classification device, conveying device and sorting roadway. The function of the control device is to recognize, receive and process the sorting signals, instruct the sorting device according to the requirements of the sorting signals, and automatically sort the commodities according to the commodity varieties, according to the commodity delivery location or according to the category of the owner. These sorting requirements can be through different ways, such as bar code scanning, color code scanning, keyboard input, weight detection, voice recognition, height detection and shape recognition, etc., input to the sorting control system, according to the sorting signals to determine a certain kind of goods should enter which sorting channel.

The automatic inspection machine adopts the electronic scale control method. After the inspected product enters the inspection machine, the weighing system recognizes that the product to be inspected enters the weighing area according to external signals, such as photoelectric switch signals, or internal level signals. According to the running speed and the length of the conveyor, or according to the level signal, the system can determine, the time when the product leaves the weighing machine. From the time the product enters the weighing platform to the time it leaves the weighing platform, the weighing module will detect the weight signal, and the weighing instrument will select the signal in the signal stabilization area for processing, so that the weight of the product can be obtained. Sorting process When the controller gets the weight signal of the product, the system will compare and sort the product with the pre-set weight range.

The detector can be integrated with all kinds of packaging production lines and conveying systems, and is mainly used to detect whether the product weight is qualified or not and whether there are missing parts in the packaging. Or according to the different weights of the articles. Control the identification, reception and processing of sorting signals, instruct detection according to the requirements of sorting signals, and automatically classify commodities according to commodity varieties, delivery places or categories of consignors. These sorting requirements can be input into the sorting control system in different ways, such as bar code scanning, color code scanning, keyboard input, weight detection, voice recognition, height detection and shape recognition, etc. According to the judgment of these sorting signals, it is decided which sorting crossing a certain commodity should enter.

The inspection machine realizes high-speed and high-precision weight detection for the products moving on the production line, and compares the detected weight with the pre-set upper and lower limits, so as to automatically sort out the products that are too light or too heavy.

The weight checker uses a continuous dynamic automatic weighing method to check the net weight of the objects, with alarms or fully automatic removal of the organization, in order to achieve a net weight check on the production line without shutting down the machine, the weighing of the products into the conveyor is adjusted to the control according to the spacing of the products and the required speed.
