Description

A dual-channel comparison counting device for ampoules Technical Field

[0001] This utility model relates to a dual-channel comparison counting device for ampoules. Background Technology

[0002] In the ampoule filling process, to accurately calculate the correspondence between input materials and output products, it is necessary to calculate the material balance. The production equipment is designed with a counting device, which detects the signal generated by the ampoule head through photoelectric sensors and performs numerical measurement through PLC logic operations. Because the ampoule will uncontrollably shake during movement, the shaking of the bottle head will cause the photoelectric sensor to generate repeated signals. The repeated signals cause the count value to deviate significantly from the true value, increasing the error in the material balance calculation. Summary of the Invention

[0003] The purpose of this invention is to design an ampoule bottle comparison dual-channel counter device, which can count ampoules online, improve the accuracy of product counting, and solve the problem of material balance calculation.

[0004] To solve the above problems, the technical solution of this utility model is as follows:

[0005] A dual-channel ampoule counting device with comparative design includes a feeding star disk with multiple slots. A trigger disk with the same axis as the feeding star disk is located above it. The trigger disk has multiple protruding teeth on its outer periphery, the same number as the slots, with each protruding tooth corresponding to a slot. A proximity switch for detecting the protruding teeth is located above the trigger disk. A bottle-measuring device for detecting the fed ampoules is located on one side of the feeding star disk. The proximity switch and the bottle-measuring device are connected to the input terminal of a PLC controller, and a display screen is connected to the output terminal of the PLC controller.

[0006] Furthermore, two sets of both the proximity switch and the bottle measuring device are installed.

[0007] Furthermore, the bottle testing device is a photoelectric sensor, and the PLC controller only takes the rising edge signal when the photoelectric sensor detects an ampoule.

[0008] Furthermore, the rising edge detection signal of the photoelectric sensor is within the time window of the proximity switch's detection signal.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This device employs a dual-channel detection method, simultaneously detecting ampoules via a proximity switch and a bottle-measuring device. The proximity switch detects the tooth position signal of the bottle delivery star disk, while the bottle-measuring device detects the signal from the ampoule itself. The PLC controller performs logical operations on these two signals, outputting a counting signal only when both signals simultaneously meet a specific condition (e.g., the tooth position signal from the proximity switch completely covers the ampoule signal from the bottle-measuring device). This dual-channel detection mechanism effectively filters out duplicate signals caused by ampoule shaking, ensuring that each ampoule is counted only once, thus significantly improving counting accuracy.

[0011] 2. By adjusting the detection distance and coverage of the proximity switch, as well as the photoelectric detection parameters of the ampoule measuring device, precise matching of the two signals can be achieved. This precise signal synchronization and calibration mechanism enables the counting device to maintain high stability and reliability in complex production environments, and can accurately count even when the ampoules are shaken violently.

[0012] 3. This device is equipped with two sets of proximity switches and bottle measuring devices, each generating two independent counting signals. The PLC controller compares these two signals in real time. If a difference is found between the count values ​​of the two signals, the parameters of the proximity switches and bottle measuring devices can be adjusted promptly until the count values ​​of the two signals are completely consistent. This real-time comparison and error elimination mechanism can completely eliminate counting errors, ensuring the authenticity and reliability of the counting results, and providing accurate data support for production process monitoring and quality control.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] As shown in Figure 1, an ampoule bottle comparison dual-channel counting device includes a bottle feeding star disk 1, which has multiple toothed grooves. A trigger disk 3 with the same axis as the bottle feeding star disk 1 is provided above the bottle feeding star disk 1. The outer periphery of the trigger disk 3 has multiple protruding teeth with the same number as the toothed grooves, and each protruding tooth corresponds one-to-one with each toothed groove. A proximity switch 4 (e.g., Omron E3Z-LS62) for detecting protruding teeth is provided above the trigger disk 3. A bottle measuring device 2 for detecting the fed ampoules is provided on one side of the bottle feeding star disk 1. The proximity switch 4 and the bottle measuring device 2 are connected to the input terminal of a PLC controller 5 (e.g., Siemens S7-1200). A display screen 6 (e.g., TPC7062K Kunlun Tongtai) is connected to the output terminal of the PLC controller 5.

[0018] Furthermore, both the proximity switch 4 and the bottle measuring device 2 are installed in duplicate. The PLC controller compares the counting results of the two channels in real time. When the difference exceeds a preset threshold, an alarm is triggered to ensure counting accuracy.

[0019] Furthermore, the bottle measuring device 2 is a photoelectric sensor (e.g., Panasonic EE-SX1010), and the PLC controller 5 only takes the rising edge signal when the photoelectric sensor detects an ampoule. Using a photoelectric sensor as the bottle measuring device effectively reduces external interference and improves signal stability and reliability. The PLC controller only takes the rising edge signal when the photoelectric sensor detects an ampoule, further optimizing the signal processing and avoiding false counting caused by signal fluctuations.

[0020] Furthermore, the rising edge detection signal of the photoelectric sensor falls within the time window of the detection signal of proximity switch 4. By ensuring that the rising edge detection signal of the photoelectric sensor is within the detection signal range of the proximity switch, the signal synchronization mechanism is further optimized, ensuring that the two signals can be precisely matched, thereby improving the accuracy and reliability of counting.

[0021] Furthermore, the display screen is a touchscreen. Operators can directly set counting parameters and view counting results via the touchscreen.

[0022] Furthermore, it also includes an audible and visual alarm connected to the PLC controller. When an abnormality occurs during the counting process, such as signal loss, signal mismatch, or counting error exceeding a preset threshold, the alarm device can issue an audible and visual alarm signal to remind the operator to handle the situation promptly.

[0023] When this utility model is in operation:

[0024] The ampoule measuring device 2 is installed near the ampoule delivery star disk 1. The ampoule measuring device 2 is suitable for scanning the ampoule heads carried on the ampoule delivery star disk 1. When an ampoule passes by, the photoelectric detection photocell obtains an optical signal. The optical signal is transmitted to the optical fiber amplifier through the optical fiber. The optical fiber amplifier converts the optical signal into an electrical signal and then outputs the electrical signal to the PLC programmable logic controller. The photoelectric detection photocell uses a rising edge signal.

[0025] The main function of trigger disk 3 is to determine the position of each slot of the bottle delivery star disk 1. Trigger disk 3 is installed above the bottle delivery star disk 1, and the protrusion of trigger disk 3 is aligned with the slot of the bottle delivery star disk 1. The position signal of a slot of the bottle delivery star disk 1 is obtained by scanning the signal of proximity switch 4 to trigger the protrusion of trigger disk 3.

[0026] The ampoule measuring device 2 sends a rising edge signal indicating that the ampoule has been detected, and the proximity switch 4 sends a signal indicating the position of the tooth groove on the ampoule delivery star disk 1. Each tooth groove position signal is counted only once. Both signals are triggered simultaneously, and the tooth groove position signal detected by the proximity switch 4 must completely cover the ampoule signal detected by the photoelectric sensor. Both signals are simultaneously input to the PLC controller 5. The PLC controller 5 outputs a counting signal when both conditions are met through internal AND logic operations. The counting is accumulated by the internal increment counter of the PLC controller 5. This method can filter out duplicate signals caused by ampoule shaking and accurately record and display the actual production values.

[0027] Two sets of bottle measuring devices 2 and proximity switches 4 are installed simultaneously. The two sets of electrical signals output by the PLC controller 5 are input to the display screen 6, which displays the cumulative count values ​​of the two sets of counters in real time. When there is a difference in the displayed values, it indicates that the position signal of each bottle delivery star disk 1 tooth groove detected by the proximity switch 4 does not completely cover the corresponding ampoule signal. The detection distance and coverage range of the proximity switch 4 can be adjusted until the two sets of data are the same, which is the actual value.

[0028] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
