Package code spraying device and using method thereof

Abstract

The invention discloses a package code spraying device and a using method thereof. The package code spraying device comprises a conveying belt, a U-shaped detector, a code sprayer and a spray head adjusting mechanism, a cargo is placed on a conveying face, the conveying belt is used for conveying the cargo placed on the conveying belt to sequentially pass through the detector and the code sprayer,the U-shaped detector comprises a transmitting end and a receiving end which are fixed on the two sides of a U-shaped groove, the transmitting end is fixed to the side face of the conveying belt, when the cargo passes through the U-shaped detector and blocks the receiving end from receiving a signal output by the transmitting end, a code spraying signal is output to the code sprayer, the code sprayer comprises a main machine and a spray head, the main machine is arranged on the side face of the conveying belt, the spray head is arranged above the conveying face, the main machine is used for receiving the code spraying signal of the detector and controlling the spray head for code spraying, the spray head adjusting mechanism comprises a supporting frame fixed to the side face of the conveying belt and an adjusting rod, the adjusting rod is provided with the spray head, and the adjusting rod moves up and down along the supporting frame to adjust the height of the spray head. The packagecode spraying device and the using method thereof solve the problems of code deviation, code repetition and code missing caused by the fact that an existing package code spraying device cannot accurately detect whether or not the cargo passes through.

Description

Technical field [0001] The invention relates to the technical field of packaging machinery, in particular to a packaging code spraying device and a method of use thereof. Background technique [0002] The existing product detection methods of tank bottom coders generally have the problem of misdetection. Such as figure 1 As shown, the detector is placed above the transport surface of the conveyor belt. The working principle of its product detection is that the infrared point signal is emitted to the bottom edge of the can by the transmitting end, so that the optical signal and the bottom edge of the can form a longitudinal and horizontal correspondence. While the cans have a certain movable space in the guardrail at both ends of the conveyor belt for transmission, the position of the cans and the light signal at the transmitting end is not fixed during transmission. When the optical signal is relatively deviated from the can, it will be detected that no can passes through, resu...
