Method and device for improving reliability of detecting short-seller cigarettes

Abstract

The invention relates to a method and a device for improving the reliability of detecting short-seller cigarettes. According to the invention, a lateral reciprocating moving rod for drawing cigarette groups, which is arranged in a molding box mechanism of a cigarette package packaging machine, is used as a power source, and outputs power to enable a moving part to perform up-and-down reciprocating motion. The manual turning handle of the device can realize the function of separating a horizontal swinging rod and a cigarette beating plate thereof from the detection position of a cigarette output passage in the operation process of a small-package cigarette packaging machine, so as to be favorable for cleaning the cigarette output passage or supplying cigarettes in time. Starting signals of an aerodynamic or electric executive component of the device are synchronous to those of a cigarette shaking roller of the small-package cigarette packaging machine; and during the cigarette shaking operation of the packaging machine, the horizontal swinging rod and the cigarette beating plate of the device are separated from the detection position of the cigarette output passage, so as to prevent the cigarette beating plate from blocking a cigarette flow in the cigarette output passage. Each touch bar arranged on the cigarette beating plate of the device and supported by a spring can retract when encountering cigarettes with a positive length difference, so as to effectively prevent the cigarettes with the positive length difference from deforming due to stress. The device provided by the invention has the outstanding advantages of simple structure and stability in operation.

Description

technical field [0001] The invention belongs to a cigarette packet packaging machine, in particular to a method and a device for improving the reliability of detection of empty cigarettes. Background technique [0002] In order to overcome the defect of empty cigarettes in the mold box of the cigarette packet packaging machine, in the prior art, an empty cigarette detector and its pneumatic removal mechanism for empty cigarettes are generally used in the lower flue of the packaging machine to detect empty cigarettes. The device is installed on the rear vertical plate of each lower flue. [0003] It has been found in practice that there are gaps of varying sizes between the inspected end of some cigarettes and the end face of the empty cigarette detector when the branched smoke in the lower flue passes through the detection position, which affects the reliability of empty cigarette detection. [0004] The utility model "Auxiliary Device for Cigarette Quality Detector in Lowe...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned utility model has the following disadvantages: 1. Since the contact block of the lateral reciprocating rod is laterally engaged with the first transmission swing arm, not only the transmission mechanism from the first transmission swing arm to the cigarette clapper is complicated, but also there are first and second The adjustment of the positional relationship between the transmission swing arms is more complicated; 2. When the cigarette packet packaging machine is in the parking state, the control swing arm of the device can stop the slapping plate in the up-spinning state away from the lower flue under the action of the cylinder. The smoke plate stops in this state, which is convenient for filling smoke and other operations

But this utility model can not meet the needs of finishing or supplementing cigarettes in the lower flue under the non-stop state of the cigarette packet packaging machine; The distance between the surface plane and the end face of the empty end cigarette detector in the lower flue is equal to the design of the length of the standard cigarette, which will cause deformation of the cigarette with a positive difference in length
