Description

Technical Field

[0001] The utility model relates to the technical field of printing machinery, and specifically relates to a finished product sampling inspection device for cigarette label printing products. Background Art

[0002] In existing cigarette label printing equipment, in order to improve the integrity and comprehensiveness of product printing by the printing equipment, different levels of printing patterns and styles are printed in separate processes during the printing process, so as to improve the forming quality of printed products.

[0003] The general methods for sampling inspection of finished cigarette label printing products are manual sampling inspection or machine sampling inspection. For example, when using machine sampling inspection, an identification mechanism is installed on the printing machine to automatically identify product defects. During sampling inspection, if a defective printed product (i.e., a non-conforming product) is identified, it will be transported to other positions. By counting the number of samples and the number of non-conforming products, the purpose of sampling inspection of finished cigarette label printing products is completed; and the transportation of non-conforming printed products is generally carried out by mechanical claws or vacuum suction cups. This transportation method requires an additional structure of a manipulator, resulting in a relatively high equipment cost. Moreover, during the transportation process by the manipulator, the conveyor belt for transporting printed products needs to stop moving to facilitate the grasping by the manipulator, and this process will reduce the processing efficiency of printed products. Content of the Utility Model

Specific embodiments

[0024] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the intended utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific embodiments, structures, features and their effects of the present invention as follows.

[0025] Embodiment: Please refer to Figures 1-5, A finished product sampling inspection device for a cigarette label printing product, comprising a conveyor belt 1 for conveying the finished product and a support body 2 arranged inside the conveyor belt 1. A first air chamber 11 communicated with an air intake system 13 is arranged inside the support body 2. A plurality of rows of air outlet holes 10 are arranged at the top of the first air chamber 11. There is an included angle between the central axis of the air outlet hole 10 and the vertical direction. A plurality of rows of first ventilation grooves 9 aligned with the air outlet holes 10 are arranged on the conveyor belt 1. The sampling inspection device further comprises an identification mechanism 8 for identifying whether there are defects in the finished product; The air intake system 13 can adopt the form of a common air compressor and related connecting pipes. Usually, the air compressor exists in the printing equipment to provide air source for the printing equipment. Therefore, in this utility model, only the first air chamber 11 needs to be connected with the air compressor through a pipe; Relevant air path connectors, such as pressure relief valves or pressure gauges, will not be elaborated too much in this article; When the finished product (the finished product of the cigarette label printing) enters the sampling inspection device through a manipulator or the upper conveyor belt, the qualified finished product is first detected and analyzed by the identification mechanism 8. Among them, the identification mechanism 8 can adopt an automatic positioning and focusing detection device based on on-line machine vision detection published with the application number CN202010795946.7 to detect the appearance and surface defects of the product, or other technologies capable of detecting the appearance and surface defects of the product. There is no excessive limitation here, as long as it can achieve the function of detecting surface defects of the product; When an unqualified finished product appears, the air intake system 13 will be started, and the air flow will be blown out from both the air outlet holes 10 and the first ventilation grooves 9 at the same time, and the finished product will be blown off the conveyor belt 1; Compared with the previous method of transporting the finished product by mechanical claws or vacuum suction cups, the method of air blowing does not require the conveyor belt 1 to stop, improves the efficiency of transporting the finished product, does not increase the structure of the manipulator, and the structure of the device is more compact; And compared with the method of transporting by the manipulator, the air blowing structure can further reduce the cost of the printing equipment.

[0026] Since the printed products of cigarette labels are generally light, when the finished products are on the conveyor belt 1, they are easily affected by external factors (such as wind, accidental touch, etc.), which will cause their positions to change, which is not conducive to the rapid detection of the identification mechanism 8 during random inspection. Therefore, in this embodiment, the interior of the support body 2 is also provided with two suction cavities 15 connected to the exhaust system 16, the first air cavity 11 is located between the two suction cavities 15, and the top of the suction cavity 15 is provided with a second ventilation groove 14, which is connected to the first ventilation groove 9; the exhaust system 16 includes a common vacuum pump and a pipeline connected thereto. When the finished product passes through the previous process and falls on the conveyor belt 1, the vacuum pump is started, and the airflow passes through the second ventilation cavity 14. The groove 14 and the first ventilation groove 9 enter the suction chamber 15 and then enter the vacuum pump. Because the finished product is located on the conveyor belt 1, the second ventilation groove 14 and the first ventilation groove 9 are blocked, affecting the air intake. Therefore, a negative pressure is generated in the suction chamber 15, so that the finished product is close to the conveyor belt 1. At this time, the position of the finished product is not easily affected by external factors. Changes; in addition, the conveyor belt 1 and the supporting body 2 in the present invention are located inside the isolation frame 20, thereby playing an isolation role, and a feeding port is provided at the end of the isolation frame 20 to facilitate the feeding of the upper-level conveyor belt; and an operating table 21 is provided at the side end of the isolation frame 20, and the operating table 21 is connected to the identification mechanism 8 to facilitate observation of the photos taken by the identification mechanism 8.

[0027] In the present embodiment, an air equalizing plate 12 is provided inside the first air cavity 11 and the air suction cavity 15; affected by the internal space of the first air cavity 11 and the air suction cavity 15, as well as the vacuum and blowing methods, the air pressure will act unevenly on the conveyor belt 1, thereby causing the first ventilation groove 9 and the air outlet 10 to produce uneven suction or thrust on the finished product. Therefore, the air equalizing plate 12 is provided to divide the internal space of the first air cavity 11 and the air suction cavity 15, so that the air flow passes evenly through the through holes on the air equalizing plate 12 to stabilize the air pressure. In addition, since the bottom of the first air cavity 11 and the air suction cavity 15 are connected to the vacuum pump or the air compressor through a pipeline, the diameter of the through hole close to the pipeline in the air equalizing plate 12 is relatively small, and the diameter of the remaining through holes gradually increases outward, thereby further ensuring the stability of the air pressure.

[0028] In this embodiment, a collecting frame 3 for collecting finished products blown off the conveyor belt 1 is provided on the side wall of the supporting body 2; the finished products blown up from the conveyor belt 1 can fall into the collecting frame 3; a material taking port 6 is provided on the side wall of the collecting frame 3, and a transparent opening and closing door is provided on the material taking port 6; the transparent opening and closing door is connected to the collecting frame 3 by magnetic attraction, and when it is necessary to take out the finished products in the collecting frame 3, the finished products can be taken out by opening the transparent opening and closing door.

[0029] In order to improve the efficiency of product sampling, when sampling finished products, the conveyor belt 1 will not stop completely. Therefore, when unqualified finished products are sampled and blown up, the finished products have the inertia of the conveyor belt 1 in the forward direction, so that they fall forward outside the collection frame 3. For this reason, in this embodiment, a vertical baffle 4 located above the conveyor belt 1 is also provided on the side wall of the collection frame 3. There is a gap between the vertical baffle 4 and the conveyor belt 1. The vertical baffle 4 is located directly above the air outlet 10 in the last row along the forward direction of the conveyor belt 1. Qualified finished products can pass through the gap, and unqualified finished products are blown up to a certain height. The vertical baffle 4 blocks the unqualified finished products from moving forward along the conveyor belt 1, so that the finished products can only move along the air flow direction. In order to prevent the unstable air pressure during the blowing process, causing the finished products to fly out of the collection frame 3, a transverse baffle 5 is provided on the top of the collection frame 3; even if the air pressure is greater than the limited air pressure, the transverse baffle 5 can block the finished products and make them fall into the collection frame 3. The transverse baffle 5 and the side wall of the collecting frame 3 are provided with a plurality of notches; while reducing the weight of the device, it is convenient to observe the number of finished products in the collecting frame 3 and the internal state (finished products stuck at the top, finished products stuck to each other, etc.), and to facilitate timely adjustment.

[0030] In other embodiments, the support body 2 is provided with support legs 19, the conveyor belt 1 is located between the support legs 19, and the support legs 19 are connected to the guide plate 7 through a width adjustment mechanism; there are two guide plates 7 that are symmetrically distributed, and the opening is trumpet-shaped. The finished product completed from the previous process falls on the conveyor belt 1 of the finished product sampling device through the previous conveyor belt. This method easily causes the position of the finished product falling on the conveyor belt 1 to be uncertain, increasing the difficulty of identification by the identification mechanism 8. Therefore, two guide plates 7 are used to guide the finished product to a fixed position in the center. A notch is provided on the support leg 19, and the width adjustment mechanism includes an adjustment plate 17 fixedly connected to the guide plate 7, a straight notch is provided on the adjustment plate 17, a threaded hole is provided on the notch, and a bolt 18 passes through the straight notch and is threadedly connected to the threaded hole to fix the adjustment plate 17 in the notch; according to the finished products of different sizes, the opening degree of the guide plate 7 can be adjusted by the adjustment mechanism.

[0031] Working principle: When the finished products are sampled, they are analyzed by comparing with the qualified finished products through the identification mechanism 8. If unqualified finished products are found, the air intake system 13 is started, and the air flow will be blown out from the air outlet 10 and the first ventilation groove 9 at the same time, so that the finished products will be separated from the conveyor belt 1 and move in the direction of the air blowing, thereby blowing the finished products away from the conveyor belt 1; the air blowing method does not need to stop the conveyor belt 1, which improves the efficiency of transporting the finished products. At the same time, the structure of the robot is not increased, and the structure of the device is more compact; and compared with the robot transportation method, the air blowing structure can further reduce the cost of printing equipment.
