Description

TECHNICAL FIELD

[0001] The utility model belongs to label processing technical field, concretely relates to a kind of online overprint monitoring type label tear waste roll collection device of multilayer label. BACKGROUND

[0002] Currently, in the production and processing of some labels, online overprint monitoring detection needs to be carried out, and after ensuring that the overprinted part is qualified, the waste part is torn off, and a waste edge roll collector is used for winding, and the label with torn-off waste edge is also wound synchronously to complete processing. However, in the process of tearing off the waste edge, the following technical problems exist:

[0003] 1) The tearing-off angle changes due to the change in the winding diameter of the waste part, which causes the tearing-off path to change. If the waste edge is narrow, tearing-off may be interrupted or discontinued, which prevents normal tearing-off, and the waste edge has a high probability of adhering to the label surface, which not only affects the automatic production efficiency of the label, but also increases the rejection rate of the label.

[0004] 2) The peeling force also changes with the change in the tearing-off angle, so the peeling force formed is very unstable, which causes a high probability of interruption of peeling, and the winding cannot be balanced due to the change in the force. INVENTION CONTENTS

[0005] The utility model solves the technical problems of the prior art and provides an improved online overprint monitoring type label tear waste roll collection device for multilayer labels.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An online overprint monitoring type label tear waste roll collection device for multilayer labels includes an online overprint monitor formed on a label transmission path, a peeler located at the rear end of the online overprint monitor, a waste edge roll collector, and a label roll collector. In particular, the peeler includes an upper peeling roller and a lower peeling roller that rotate towards each other. The surface of the upper peeling roller is formed with anti-slip grooves. The label passes around the lower peeling roller from bottom to top, and the peeling point formed by the label is located at the top of the lower peeling roller. At the same time, the covering angle of the label is between 180° and 270°. The upper peeling roller is located above the left side of the peeling point. The torn-off waste edge passes around the upper peeling roller upwards and is rolled by the waste edge roll collector while maintaining tangency to the right. The torn-off label is transmitted downwards and to the right and is rolled by the label roll collector.

[0008] According to one specific implementation and preferred aspect of the utility model, the upper peeling roller includes a roller body, and a plurality of peeling columns uniformly distributed around the circumference of the roller body. An anti-slip groove is formed between each adjacent two peeling columns. Based on the relatively stable peeling force provided by the peeling columns, the implementation peeling reduces the probability of interruption of the waste edge.

[0009] Preferably, the peeling column section is polygonal. The contact force provided by the polygon has an anti-skid effect.

[0010] In some embodiments, the length of the label wound on the upper peeling roller is at least 1 / 4 of the circumference of the upper peeling roller. Generally, the formed arc length is 1 / 4 of the circumference of the upper peeling roller, which maintains the relative fit and is more conducive to peeling.

[0011] According to another specific implementation and preferred aspect of the present application, the waste edge winder comprises left and right extending slide rails, a slide base mounted on the slide rails, a waste edge winding shaft mounted on the slide base, and a first power motor, wherein the wound waste edge roll is kept tangent to the upper peeling roller based on the sliding motion of the slide base. The active adjustment based on the tangent fit winding avoids the occurrence of interruption caused by winding deviation.

[0012] According to another specific implementation and preferred aspect of the present application, the label winder comprises a traction roller set at the bottom of the lower peeling roller, a winding shaft at the right side of the traction roller set, and a second power motor. Based on the traction power, it is not only convenient to wind, but also convenient to peel.

[0013] Preferably, the traction roller set comprises left and right roller bodies moving towards each other, wherein the label passes around the right roller body to the winding shaft.

[0014] In addition, a bottom support platform is further arranged at the bottom of the online register monitor, wherein a monitoring channel is formed between the bottom support platform and the online register monitor, and the label is translated from the monitoring channel to the front transmission by the bottom support platform. The label is kept in a horizontal state for detection, which improves the accuracy of detection.

[0015] Preferably, the online register monitor is movably installed on the track based on the track extending along the width direction of the label. The lateral adjustment is made to meet the register detection at different positions.

[0016] In some embodiments, the track comprises a track body, an upper guide shoe module and a lower guide shoe module formed on the track body, and the base of the online register monitor is matched and connected with the upper guide shoe module, the lower guide shoe module and the track body. Not only is the installation convenient, but also the movement guide line formed is more stable, which is conducive to online detection.

[0017] Compared with the prior art, the present application has the following advantages due to the implementation of the above technical solutions:

[0018] In the existing label waste edge collection, the tear-off angle changes due to the change of the winding diameter of the waste part, if the waste edge is narrow, the tear-off will be disconnected or interrupted, which will affect the normal tear-off, and the waste edge will be attached to the label surface with a high probability, which not only affects the automatic production efficiency of the label, but also increases the scrap rate of the label; at the same time, the peeling force will change with the change of the tear-off angle, therefore, the formed peeling force is very unstable, which leads to a high probability of interruption of peeling, and the winding cannot be balanced due to the change of the force, and the like. The structure of the online overprint monitoring type label tear-off and winding device for multi-layer labels is designed as a whole, and the deficiencies and defects of the prior art are ingeniously solved. After adopting the online overprint monitoring type label tear-off and winding device for multi-layer labels, based on the layout of the online overprint monitoring instrument and the double peeling rollers, online detection of overprint is carried out first, and then the waste edge is peeled off and wound under the corresponding peeling force, and the label with the waste edge is wound by the label winder, so as to complete the winding of the label. Therefore, on the one hand, based on the same angle and the same peeling force, the waste edge and the label are synchronously wound, the formed winding interruption probability is low, and the formed winding efficiency and quality can meet the actual demand; on the other hand, based on the winding of the waste edge, the anti-skid and tangential winding are further reduced, and based on the layout of the online overprint monitoring instrument, the online detection needs of the label overprint are met.
