Labeler

Abstract

The invention provides a labeling machine which comprises a label feeding and conveying device, a label coating device, a position detecting device and a controlling device, wherein, the label coatingdevice comprises a telescopic rod and a picking and coating component arranged at the end part of the telescopic rod, and the position detecting device sends preset signals when a product reaches thepreset trigger position of the label coating device; the controlling device controls the telescopic rod to move according to the signals, controls the telescopic rod to perform the extension motion when the product reaches the preset trigger position of the label coating device, and ensures the telescopic rod to extend to the extension position when the product reaches a preset coating position,to perform labeling to the front side surface of the product, and controls the telescopic rod to retract to a retracting position after the labeling is accomplished, to ensure the product which is labeled to be allowed to continuously move with a conveying chain. The labeling machine can automatically paste the label onto the front part of the product, the operating efficiency is improved, and theartistic appearance of the product is ensured.

Description

technical field [0001] The invention relates to a device for pasting labels on products, in particular to an automatic labeling machine capable of pasting labels on the front of products. Background technique [0002] see figure 1 , figure 2 As shown, the current labeling machine generally includes a label supply conveying device (not shown) with a paper separator 801, and the paper separator 801 is positioned at the side of the product conveying chain 800 (such as figure 2 shown) or above (as figure 1 shown), the label supply conveying device will be combined with the label 803 (such as a bar code) on the self-adhesive paper 802 to the paper separator 801, and when the product 804 passes through the position of the paper separator 801, the label 803 (bar code) from Separate the self-adhesive paper 802 and attach it to the side or top surface of the product 804 to complete the pasting of the sticker 803. However, most of the existing labeling machines can only paste th...

Problems solved by technology

However, most of the existing labeling machines can only paste the barcode on the top of the product (for brick-shaped products) or on the left and right sides (relative to the direction of motion), which is limited by the forward movement of the product on the conveyor chain along the direction of motion. It is difficult to meet the requirement of pasting labels (such as barcodes) on the front of brick-shaped products with a labeling machine

However, some products currently on the market require the label to be pasted on the front of the product. For example, the six-pack product of liquid milk requires the barcode to be pasted on the front of the product and cover the original printed barcode on the six-pack product. Due to the current market It is difficult for the labeling machine on the market to achieve this function. The factory can only stick the barcode by manual labeling, which not only consumes a lot of manpower, but also affects work efficiency, and the barcode after manual sticking is not beautiful, which affects the appearance of the product.
