Description
Technical Field
The invention relates to backing paper-free labeling equipment, in particular to equipment for labeling cylindrical products with smaller radial sizes and longer axial sizes.
Background
In the prior art, workpieces with short length and large diameter can be automatically packaged and labeled, and the bonding between the workpieces and the labels is mainly realized through rubbing and rolling bonding of the workpieces and the labels, so that the labels are wrapped on the surfaces of the workpieces. However, certain workpieces, such as firework color bead cylinder products with partial specifications, have long axial length of a cylindrical cylinder body of 200-1200 mm generally and have diameters of only 12-50 mm, and the prior art has difficulty in realizing automatic packaging labeling operation of the cylinder body. In addition, similar situations exist for roman candles, confetti, etc. for firework products only.
One of the important reasons is that the length of the label corresponding to such a workpiece is long and the width is small (i.e., the elongated label), meanwhile, the label is thin, the posture and the position of the label cannot be controlled in the process of cutting and conveying the label to the attaching station, and particularly, the alignment of the length direction of the label is difficult to keep. As shown in fig. 1, when the label 20 is fed to the work piece 21 for roll bonding, the entrance side 201 of the label 20 is not simultaneously in flush contact with the work piece 21, resulting in misalignment and distortion when the label 20 is rolled onto the work piece 21.
