Embodiment Construction
[0025] The present invention will be described below in conjunction with the accompanying drawings and embodiments.
[0026] Referring to Fig. 1, the measuring device for the passing number of bottle caps on the high-speed production line of the present invention is used to measure the passing number of bottle caps on the bottle cap conveying line body 1, and mainly includes a star wheel counting mechanism 2, an air blowing device 7, a first sensor 4. The second sensor (5), the third sensor (6) and the main controller (set in the main control cabinet). Three sensors are used to sense whether there is a bottle cap at the corresponding part, and in this embodiment, a photoelectric sensor is used.
[0027] see figure 2 with image 3 , The star wheel counting mechanism mainly includes a servo drive motor, a star wheel 3, and a star wheel mounting plate 12. The star wheel 3 is fixed directly below the line body 1 through the mounting plate 12. The radius of each tooth is slightl...

The invention belongs to the technical field of food packaging industry and relates to a device and method for metering passing quantity of bottle caps on a production line. The device comprises a star wheel metering mechanism, a blowing device, three sensors and a master controller, wherein the radius of each gear tooth of star wheels of the star wheel metering mechanism is slightly larger than that of the bottle caps, the depth of the gear tooth is slightly smaller than the radius of the bottle caps, and the gear tooth is used for carrying the bottle caps along movement of a conveying line of the bottle caps. The blowing device is fixed on the upstream of the star wheel metering mechanism to be used for blowing along a movement direction of the conveying line of the bottle caps. The master controller measures passing quantity of the bottle caps according to calculation of rotated wheel teeth quantity of the star wheel, adjusts rotational speed and blowing pressure of the star wheel according to sensing signals input by the three sensors, coordinates passing speed of the bottle caps and corrects passing quantity of the bottle caps. The device and the method achieve metering and counting correction of passing quantity of the bottle caps on the high-speed production line. The device and method has the advantages of being accuracy in metering, simple in structure and easy to apply.
Description
technical field [0001] The invention belongs to the technical field of food packaging industry and relates to a bottle cap measuring device. technical background [0002] There are usually two ways to measure the passing number of caps on a high-speed production line: [0003] 1. The way of weighing, the principle is as follows: [0004] where G 1 is the total weight after packing, G 2 is the weight of the empty box, G 0 is the weight of each bottle cap, and n is the number of bottle caps in the box. [0005] This measurement method needs to assume that each bottle cap has the same weight, and the accuracy of the weighing device is high enough. But usually, the number of bottle caps measured by this method has a large deviation due to the error of the bottle cap's own weight and the error of the weighing device. [0006] 2. The method of counting by sensor [0007] The method of using sensor counting is to assume that when the bottle cap passes through the sensor in...
