[0001] This utility model relates to the field of packaging machinery, and in particular to a high-speed rotary labeling machine. Background Technology
[0002] In the packaging industry, product labels play a crucial role, not only carrying core elements such as brand information and product descriptions, but also directly affecting the product's appearance quality and market competitiveness. Traditional manual labeling methods, due to inefficiency, inaccurate label placement, and labels easily wrinkling or falling off, are no longer suitable for the demands of modern large-scale, high-efficiency production. With technological advancements and the widespread application of industrial automation, simple labeling machines have gradually replaced manual labeling.
[0003] However, current labeling machines on the market, when labeling round bottles, especially vials, are prone to tipping over during the labeling and conveying process in order to meet the demands of high-speed production. This affects the continuity of subsequent production. Furthermore, existing labeling machines lack sufficient labeling accuracy, with errors generally exceeding ±1mm, and exhibit poor stability, severely impacting the product's appearance quality.
[0004] Therefore, it is particularly important to develop a high-speed labeling machine that can automatically and quickly apply labels, has stable transmission, is not prone to bottle tipping, and ensures the continuity of subsequent production. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a high-speed rotary labeling machine is applicable to labeling round bottles, especially vials. The labeling machine includes a casing 1, which includes a three-color warning light mounted on its top. The three-color warning light is used to alert workers to malfunctions that occur during the equipment's production process. The machine housing 1 is equipped with a conveyor belt 2, which is divided into front and rear sections. The feeding end of the conveyor belt 2 is connected to a feeding disc 10. Along the transmission direction of the conveyor belt 2, a bottle-removing section 22, a bottle-removing detection device 100, and a screw bottle-separating mechanism 3 are arranged in sequence. The end of the screw bottle-separating mechanism 3 is connected to an infeed dial 4. The infeed dial 4 is connected to a star disk mechanism 5. On one side of the star disk mechanism 5 and along the transmission direction of the star disk mechanism 5, a label feeding device 6, a rolling mechanism 7, and a non-conforming label detection system 200 are arranged in sequence. The star disk mechanism 5 is connected to an outlet dial 300, which is connected to the rear conveyor belt 2. The rear end of the outlet dial 300 is equipped with a removal mechanism 8, which is located on the conveyor belt 2. The bottle-removing detection device 100 is configured to detect bottles that are missed by the removal section and bottles that are reversed during subsequent conveying. Once a reversed bottle is detected, a three-color warning light will activate an alarm program based on the detection result. Simultaneously, the conveyor belt 2 will reduce its conveying speed or stop to provide sufficient processing time for workers. The rejection mechanism 8 is configured to reject unqualified labels.
[0028] In practical applications, a bottle-pushing power device 9 is installed along the conveying direction of the conveyor belt 2 and at the rear end of the rejection mechanism 8. Since there is a section at the end of the conveyor belt 2 that is not covered by the belt, this will adversely affect the output of round bottles. Therefore, the bottle-pushing power device 9 is specifically configured to provide the necessary power to ensure that bottles can be smoothly pushed out, thereby effectively preventing bottles from accumulating at the end of the conveyor belt 2. The bottle-pushing power device 9 is equipped with a bottle-pushing power adjustment device 91, which is configured to adjust the height of the bottle-pushing power device 9 and its width relative to the centerline of the conveyor belt 2 so that it can be used with round bottles of different sizes.
[0029] In practical applications, the label feeding device 6 includes a mounting plate 61. The mounting plate 61 is equipped with a label feeding device 62 for supplying label tape, a label pulling device 63 for pulling the label tape, a label peeling device 64 for peeling the label from the backing paper, and a backing paper recycling device 65 for winding up the backing paper. The mounting plate 61 also includes a printing device and a drying device. The label pulling device 63 pulls the label tape through the printing device (not shown) and the drying device before connecting to the label peeling device 64. The printing device is configured to print label information, and the drying device is configured to dry the printed labels to prevent subsequent scratching that could blur the label information. Preferably, the mounting plate 61 also includes a label feeding device adjustment device to adjust the height of the label feeding device 6 and its distance relative to the labeling star disk mechanism 5.
[0030] In practical applications, the feeding disc 10 includes a feeding guardrail 103 disposed on the outer periphery of the feeding disc 10. The feeding disc 10 is equipped with a guide block 102 and a guide block limiting post 104. The guide block 102 guides the conveying direction of the round bottle, and the guide limiting post restricts the position of the guide block 102. Preferably, the distance between the end of the guide block 102 near the feeding guardrail 103 and the feeding guardrail 103 is set according to the diameter of the round bottle, preferably slightly larger than the diameter of the round bottle, to ensure that the probability of bottle tipping is effectively reduced and the round bottle is conveyed smoothly backward along the feeding guardrail 103, thereby reducing the occurrence of bottle tipping to a certain extent. The feeding disc 10 is equipped with a material shortage detection device 101. When a material shortage is detected, the feeding disc 10 is configured to slow down or stop based on the detection result of the material shortage detection device 101 to avoid energy waste. Preferably, the feeding disc is connected to a feeding port, which can be manually fed or connected to a feeding machine.
[0031] In practical applications, the rolling mechanism 7 includes a rolling mechanism mounting base 72 on the housing 1. The rolling mechanism mounting base 72 is provided with a rolling mechanism adjustment device 71 and a wheel-attached rolling device 73. The rolling mechanism adjustment device 71 is configured to adjust the height of the wheel-attached rolling device 73 and its distance relative to the star disk mechanism 5, so that it can be used for rolling labeling operations on round bottles of various sizes.
[0032] In practical applications, the screw bottle-separating mechanism 3 includes a bottle-separating screw 31 disposed on one side of the conveyor belt 2. The screw 31 is connected to a screw power transmission mechanism 33 and a screw adjustment device 32. The screw power transmission mechanism 33 is connected to the power source of the star disk mechanism 5, ensuring that the transmission speeds of the bottle-separating screw 31 and the star disk mechanism 5 are synchronized, thus ensuring the continuity of the labeling process. The screw adjustment device 32 is configured to adjust the height of the bottle-separating screw 31 and its width relative to the centerline of the conveyor belt 2, making it suitable for separating round bottles of various sizes. By setting the screw bottle-separating mechanism on the conveyor belt, the uniformity of bottle separation is ensured, allowing round bottles to smoothly enter the star disk mechanism 5, effectively reducing the breakage rate.
[0033] In practical applications, the screw adjustment device 32 includes a fixed base 321 fixedly mounted on the housing 1. A movable block 322 is connected to the fixed base 321. A width adjustment screw 323 is horizontally threaded through the movable block 322. One end of the width adjustment screw 323 is connected to the fixed base 321, and the other end is connected to a width adjustment handwheel 324. A height adjustment screw 326 is vertically threaded through the movable block 322. One end of the height adjustment screw 326 is connected to a screw fixing block 325, and the other end is connected to a height adjustment handwheel 327. The screw fixing block 325 is fixedly connected to the bottle-separating screw 31. The height adjustment handwheel 327 drives the height adjustment screw 326 to rotate, thereby causing the movable block 322 to move on the fixed base 321, so as to adjust the width of the bottle-separating screw 31 relative to the centerline of the conveyor belt 2. At the same time, the width adjustment handwheel 324 drives the width adjustment screw 323 to rotate, and the rotation of the width adjustment screw 323 drives the bottle-separating screw 31 to move up and down, thereby realizing the adjustment of the height of the bottle-separating screw 31.
[0034] In practical applications, the chassis 1 includes a main chassis 11 and a feeding chassis 12. The feeding chassis 12 is located below the feeding disc 10. The bottom of the chassis 1 is provided with feet 13 and casters 14 to facilitate the movement and fixation of the labeling machine.
[0035] In practical applications, conveyor belt guardrails 21 are provided on both sides of the conveyor belt 2, and the bottle-removing part 22 is provided on the conveyor belt guardrails 21; a bottle-collecting box 23 is provided below the bottle-removing part 22. When the round bottle is conveyed to the bottle-removing part 22, the removal part occupies about half of the position of the conveyor belt 2. The upright bottle can be smoothly conveyed along the conveyor belt 2 because of its flat bottom. The inverted bottle, due to its round bottle arc surface structure, will roll on the conveyor belt 2 when passing through the bottle-removing part 22 and eventually slide off the conveyor belt 2 into the bottle-collecting box 23.
[0036] In practical applications, the bottle inversion detection device 100 is located at the front end near the screw bottle separating mechanism 3. The bottle inversion detection device 100 is equipped with a bottle inversion detection adjustment device, which enables it to more accurately detect bottles of various sizes inversion.
[0037] In practical applications, the chassis is equipped with a human-machine interface unit, which facilitates workers to operate the labeling machine.
[0038] Material is supplied via a feeding disc 10, which drives the material into the conveyor belt 2. The conveyor belt 2 transports the bottles to the screw-type bottle-separating mechanism 3, which then transfers them to the infeed dial 4. The infeed dial 4 further transfers the bottles to the star-plate mechanism 5, achieving precise labeling. The label-feeding device 6 provides the label and affixes it to the bottle surface. The rolling mechanism 7 applies rolling pressure to the label, ensuring it is firmly and tightly adhered to the bottle. The non-conforming label detection system 200 detects bottles with non-conforming or missing labels. Upon detection, the rejection mechanism 8 immediately activates, rejecting such bottles. Bottles with valid labels continue to be transported by the conveyor belt 2 and pushed to the next process by the bottle-pushing power device 9.
[0039] The advantages of this invention are as follows: The feeding disc effectively reduces bottle tipping during transport, ensuring stable material supply; the shortage detection device effectively reduces energy waste; the bottle tipping rejection section and detection device effectively remove tipped bottles and detect any subsequent tipping during transport, preventing bottle jamming at the screw bottle separating mechanism and avoiding labeling machine malfunctions, thus ensuring production continuity; the label dispensing device is equipped with a printing and drying unit, allowing for real-time label printing and drying of freshly printed labels. This invention avoids blurry label information, ensuring labeling quality. The bottle-pushing power device prevents round bottles from piling up at the end of the conveyor belt. A screw-type bottle-separating mechanism on the conveyor belt ensures uniform bottle separation, allowing round bottles to smoothly enter the star disk mechanism 5, effectively reducing breakage. A screw power transmission mechanism connected to the power source of the star disk mechanism ensures synchronized transmission between the two mechanisms. A screw adjustment device allows for adjustment of the screw's height and width relative to the conveyor belt centerline, making it suitable for separating round bottles of various sizes. This invention provides a high-speed rotary labeling machine that effectively reduces bottle tipping and achieves high-precision, high-speed, and highly stable labeling operations.
