Description

Technical Field

[0001] The present invention relates to a device for detecting the circumference of cigarette rods, and more particularly to a portable vertical rotation measuring device for detecting the circumference of cigarette rods. Background Art

[0002] During the production of cigarettes by a cigarette making machine, technical operators are required to manually detect the circumference of cigarette rods on the production line at regular intervals and in fixed quantities using a cigarette rod circumference gauge. This manual detection process is cumbersome, slow, and has a large detection error. The cigarette rod circumference gauge determines whether it is appropriate by inserting the cigarette rod into an opening with a specified size. When it can be freely inserted, it can be determined as qualified.

[0003] This detection process is a relatively important part of the entire production line, ensuring the production process standards of cigarette rods and the stability of subsequent process production. There are certain errors and uncertainties in detecting the circumference of cigarette rods through the cigarette rod circumference gauge. To reduce the production losses caused by it, technicians will also grab cigarette rod samples on the production line and send them to the quality inspection office to obtain accurate data on the circumference of cigarette rods using a comprehensive measuring table. It takes at least 5 minutes from grabbing the sample to obtaining the accurate measurement data. During these 5 minutes, at a production rate of 6000 - 12000 cigarettes per minute for the cigarette making machine, at least 40000 cigarettes have been produced on the cigarette rod production line. Once the circumference data of the cigarette rods is unqualified, then these cigarette rods will all become unqualified products, resulting in a large amount of production waste. Summary of the Invention

The measurement result of the circumference of the cigarette 1 to be measured is directly displayed on the touch screen 102 as "Current value: 24.482mm ", that is, the circumference of the current cigarette 1 to be measured meets the production process standard.

[0016] As Figure 2 shown, inside the device housing 103 is the core component for measurement of the present invention. The portable vertical rotation measuring device for cigarette circumference detection includes a driving motor 5, a laser measurement sensor 6, a rotary measurement cylinder assembly 8, a slewing bearing 10, a cylindrical gear 11 and a profile base frame 13; the upper part of the rotary measurement cylinder assembly 8 is directly opposite to the cigarette measuring hole of the device housing 103 for inserting the cigarette 1 to be measured, and the lower part passes through and is fixed to the inner ring of the slewing bearing 10; the driving motor 5 and the slewing bearing 10 are installed on the profile base frame 13, and the driving motor 5 drives the rotary measurement cylinder assembly 8 to rotate through two adjacent sets of cylindrical gears 11, and the circumference of the cigarette 1 to be measured is measured by the laser measurement sensor 6.

[0017] The profile base frame 13 is fixed inside the device housing 103, and it includes a support platform and support legs. The left and right sides of the support platform are fixedly installed at the bottom of the device housing 103 through the support legs. The two sets of cylindrical gears 11 have the same structure, that is, the number of teeth and the module are the same, and they are located below the support platform, and are respectively the first gear and the second gear.

[0018] The driving motor 5 is fixedly installed on the profile chassis 13 by the first pan head screw 7. The driving motor 5 is installed on the front side of the support platform of the profile chassis 13, with its rotating shaft arranged downward. The rotating shaft passes through the support platform and is connected to the first gear. The first gear is connected to the second gear, and the second gear is connected to the lower end of the rotary measurement cylinder assembly 8.

The inner ring is fixedly connected to the rotary measurement cylinder assembly 8. Further, the rotary measurement cylinder assembly 8 is fixed to the inner ring of the slewing bearing 10 by the cylinder head screw 9.

[0020] A pair of laser measurement sensors 6 are provided. One is the emitting end (only emits laser, no data), and the other is the receiving end (used to measure the circumference of the cigarette). They are installed on the left and right sides of the sensor fixing bracket 15 by the first pan head screw 7. The sensor fixing bracket 15 is installed on the profile chassis 13 by the countersunk head screw 14. At this time, the two groups of laser measurement sensors 6 are located on the left and right sides of the rotary measurement cylinder assembly 8 and can measure the cigarette 1 to be measured.
