Description

Technical Field

[0001] This utility model relates to the field of eye drop bottle manufacturing technology, and in particular to a device for detecting and removing missing labels from transparent eye drop bottles. Background Technology

[0002] Labeling is a crucial step in the production of eye drop bottles. Currently, after labeling, the integrity of the labels is typically checked manually or with simple sensors, but this method has several problems. Firstly, manual inspection is inefficient and prone to fatigue, making it difficult to meet the high-speed demands of modern production lines. Secondly, existing automated inspection equipment is mostly designed for opaque bottles, making it less adaptable to transparent bottles and prone to inaccurate detection due to light refraction or reflection. Furthermore, existing equipment is not efficient enough in rejecting bottles with missing labels, often resulting in incomplete rejection or the wrong rejection of qualified products.

[0003] Patent application CN201710198510.8 discloses a label testing machine that detects the adhesion force of a label by attaching it to a heavy object and then testing the continuous adsorption force of the label on the heavy object. The machine is fast and reliable. It includes a base plate with a vertical plate on it. A vertically arranged linear guide rail is provided on the front end of the vertical plate. A push-pull force gauge is fixed to the front end of a push-pull force gauge mounting plate, and the rear end of the mounting plate is fitted into the linear guide rail. A stainless steel top of the push-pull force gauge is vertically arranged facing upwards. A support plate is arranged directly above the stainless steel top, supported by a support structure above the base plate. A vertical through hole is provided on the support plate corresponding to the top of the stainless steel top. The upper periphery of the vertical through hole is recessed to form a support groove. The bottom of a weight block is supported in the support groove, and a through hole is provided on the weight block corresponding to the vertical through hole.

[0004] However, the label inspection machine in the aforementioned patented technology cannot solve the defects of the existing technology, nor does it provide any technical inspiration for solving the existing problems. Therefore, there is an urgent need for a high-efficiency label inspection and rejection device for transparent eye drop bottles to improve production efficiency and product quality. Utility Model Content

[0005] The purpose of this invention is to provide a transparent eye drop bottle label detection and rejection device to solve the problems mentioned in the background art.

[0006] (1) How to solve the problems of low detection efficiency, poor adaptability to transparent bottles and incomplete rejection in the existing technology.

The deflector wheel can drive the eye drop bottle into the guide rail.

[0018] Furthermore, it also includes a collection box with an opening at the top, the opening of which is located below the end of the rejection track.

[0019] With this structure, eye drop bottles flow into a belt conveyor after being labeled. The bottle-separating component separates the bottles and sends them into a guide rail. The detection component checks the labels on the bottles. If a missing label is detected, the system alarms, the bottle-blowing component starts, and blows the missing label bottle into the rejection track until it completely leaves the conveyor, at which point the alarm is deactivated.

[0033] This transparent eye drop bottle label detection and rejection device includes a belt conveyor 100, a detection component, a bottle separating component, a bottle blowing component, a guide rail, a rejection rail 300, a collection box 800, and multiple sets of fixing components.

[0034] The belt conveyor 100 is a commercially available and mature product. The belt conveyor 100 is arranged behind the labeling equipment in the eye drop bottle production line and is used to transport labeled eye drop bottles.

[0035] The guide rail includes a first guide plate 210 and a second guide plate 220. The first guide plate 210 and the second guide plate 220 are respectively suspended and fixed on the upper side of the conveyor belt 110 of the belt conveyor 100 by several fixing components. The direction of the guide rail is consistent with the transmission direction of the belt conveyor 100. The first guide plate 210 has two windows opened sequentially along its length. The second guide plate 220 of the guide rail has a notch 221. The windows and the notch 221 are used to cooperate with the detection and rejection operation.

[0036] The rejection track 300 begins at the notch 221 of the guide track and extends outward in the width direction of the belt conveyor 100. The rejection track 300 is used to guide bottles with missing labels away from the production line. The collection box 800 is placed on the ground with an opening at the top, which is located below the end of the rejection track 300.

[0037] The fixing assembly includes a first fixing seat 410 and a first support rod 420. The first fixing seat 410 is fixedly connected to the two side supports 120 of the belt conveyor 100. One end of the first support rod 420 is fixedly connected to the first fixing seat 410, and the other end of the first support rod 420 is fixedly connected to the first guide plate 210 or the second guide plate 220.

[0038] The detection assembly includes three detection switches 510, a second fixing base 520, and a second support rod 530. Each of the three detection switches 510 can independently detect the label on the transparent eye drop bottle. If none of the three detection switches 510 detects a label, it is determined that a label is missing and an alarm is triggered. The second fixing base 520 is fixedly connected to the bracket 120 of the belt conveyor 100. One end of the second support rod 530 is fixedly connected to the second fixing base 520, and the detection switches 510 are fixedly connected to the other end of the second support rod 530. The detection switches 510 extend into the guide rail and can detect the label on the transparent eye drop bottle.

[0039] The blow molding assembly includes a nozzle 610, a solenoid valve 620, a third mounting base 630, and a third support rod 640. The nozzle 610 also extends into the guide rail and is connected to an external air source via the solenoid valve 620. The nozzle 610 is aligned with the notch 221 of the second guide plate 220. The third mounting base 630 is fixedly connected to the bracket 120 of the belt conveyor 100. One end of the third support rod 640 is fixedly connected to the third mounting base 630, and the nozzle 610 and the solenoid valve 620 are fixedly connected to the other end of the third support rod 640. The blow molding assembly uses high-pressure gas to blow bottles with missing labels into the rejection track 300.

[0040] The bottle-separating assembly includes a deflector wheel 710, a deflector motor 720, and a fourth fixed base 730. One side of the fourth fixed base 730 is fixedly connected to the bracket 120 of the belt conveyor 100, and the other side of the fourth fixed base 730 extends to the upper side of the conveyor belt 110 of the belt conveyor 100. The deflector motor 720 is fixedly connected to the fourth fixed base 730. The deflector wheel 710 is mounted on the output shaft of the deflector motor 720. The deflector wheel 710 is located near the beginning of the guide rail. Several levers are provided on the side wall of the deflector wheel 710. The deflector wheel 710 can drive the eye drop bottles into the guide rail. The bottle-separating assembly is used to separate the eye drop bottles and send them into the guide rail in an orderly manner to avoid mutual interference during testing.

[0041] In the eye drop bottle production line, eye drop bottles after passing through the labeling equipment flow into the belt conveyor 100. Labeled transparent eye drop bottles are separated by the bottle separating component. When an eye drop bottle is detected by the detection switch 510, the detection begins. If any one of the three detection switches 510 detects the label on the eye drop bottle, it is considered that the label has been affixed. If none of the three detection switches 510 detects the label, it is considered that the label has been missing, and the system alarms. When the missing label bottle passes through the notch 221 of the second guide plate 220, the solenoid valve 620 of the bottle blowing component opens, and high-pressure gas blows through the nozzle 610, blowing the transparent eye drop bottle with the missing label into the rejection track 300 until the transparent eye drop bottle with the missing label is blown out of the belt conveyor 100, and the alarm is cleared at the same time.

[0042] This transparent eye drop bottle label detection and rejection device can utilize a PLC module to effectively coordinate the belt conveyor 100, bottle separating assembly, detection switch 510, and solenoid valve 620 of the blow molding assembly.

[0043] This invention significantly improves the efficiency and accuracy of transparent eye drop bottle label detection by optimizing the detection and rejection process, while also achieving efficient rejection of defective products, thus possessing significant practical value.

[0044] The above description is only one embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered to fall within the protection scope of the present utility model.
