Description

Technical Field

[0002] Dual-component thermal labels are used to monitor the cumulative heat exposure of heat-sensitive items during storage or transportation at low temperatures, and warn of overheated products through color changes and contrast to ensure the safety and effectiveness of product use.

[0003] The so-called two-component thermal label consists of two physically independent components before use. When in use, the two components are assembled to form a finished label. The finished label is attached to the product that needs to record the heat exposure history. This can accurately display the heat exposure history experienced by the product during transportation, making it easier to determine whether the product has expired.

[0004] Thermal labels require comprehensive consideration of all processes, from production to use, to fully guarantee product effectiveness. Specifically, the use phase includes assembly and labeling. Currently, due to the lack of labeling machines specifically designed for this combination label, these two processes must be completed on two separate production lines.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of this application.

[0051] The present application embodiment provides a multi-channel automatic assembly labeling device, such as Figure 1-Figure 7As shown, the multi-channel automatic assembly and labeling equipment includes: a frame 1, an assembly unit, a labeling unit, and a product conveying unit located on the frame 1. The assembly unit includes a peeling section that separates the first label assembly 10 and an applying section that applies the remaining first label 10a to the second label assembly 20 to form a finished label assembly 30. The peeling section includes a first unwinding shaft 11a for the first label assembly 10. The first label assemblies 10 are arranged in multiple rows along the winding direction of the first unwinding shaft 11a, with each row having multiple labels spaced axially along the first unwinding shaft 11a. The applying section includes a second unwinding shaft 21a for the second label assembly 20. The second label assemblies 20 are arranged in multiple rows along the winding direction of the second unwinding shaft 21a, with each row having multiple labels spaced axially along the second unwinding shaft 21a. The number of first label assemblies 10 and second label assemblies 20 in each row, as well as the spacing between adjacent ones, are equal.

[0052] Along the conveying direction of the finished label assembly 30, as Figure 2-Figure 5 As shown, the labeling unit is located downstream of the assembly unit, and the labeling unit includes a feeder device, a second label peeling plate 38, a label feeding positioner S4, a lower label plate 43a and a lower label driving cylinder 43b. The feeder device can separate each row of finished label assemblies 30 into finished labels 30a and finished base films 30b according to the information sent by the label feeding positioner S4, and store the finished base films 30b, and transport the finished labels 30a to the top of the product 40 to be labeled. The lower label driving cylinder 43b drives the lower label plate 43a to move downward and press the end of the finished label 30a away from the second label peeling plate 38 onto the product 40 to be labeled. Then the feeder device drives the second label peeling plate 38 to retreat, so that the finished label 30a is completely attached to the product 40 to be labeled.

[0053] like Figure 2 、 Figure 6 、 Figure 7 As shown, the product conveying unit to be labeled includes a conveying platform, on which are provided a conveying member 48a, a guide rail 41, a first drive motor 48b, an inlet valve 45a, an inlet drive cylinder 45b, a discharge valve 46a and a discharge drive cylinder 46b. The guide rail 41 is provided above the conveying member 48a to define the transmission path of the product 40 to be labeled. The first drive motor 48b is connected to the conveying member 48a to drive the conveying member 48a to rotate circumferentially; the inlet drive cylinder 45b is connected to the inlet valve 45a to drive the inlet drive cylinder 45b to rotate circumferentially. The discharge driving cylinder 46b is connected to the discharge valve 46a to drive the discharge valve 46a to extend into the guide rail 41 or withdraw from the guide rail 41; the feed valve 45a and the discharge valve 46a are arranged in sequence along the transmission direction of the product conveying unit to be labeled, and the number and spacing of the products 40 to be labeled between the feed valve 45a and the discharge valve 46a are equal to the number and spacing of the finished labels 30a after being attached by the second unwinding shaft 21a.

[0054] In this embodiment, the first label assembly 10 separates the first label 10a and the first base film 10b in the peeling section. The first label 10a is then attached to the upper surface of the second label assembly 20 in the subsequent assembly section, forming a finished label assembly 30. As the finished label assembly 30 passes through the feeder device of the labeling unit, the feeder device separates the finished label 30a from the finished base film 30b. The finished label 30a is then attached to the product 40 to be labeled through the coordinated action of the label lowering drive cylinder 43b, the label feed positioner S4, the first drive motor 48b, the feed drive cylinder 45b, and the discharge drive cylinder 46b. The assembly and labeling processes can be completed on a single production line, eliminating the need for low-temperature storage of the finished label assembly 30 after separate assembly. This reduces the risk of heat exposure to the finished label assembly 30 during use and reduces storage costs.

[0055] Furthermore, the multi-channel automatic labeling assembly system has multiple first label assemblies 10 arranged side by side on the first unwinding shaft 11a, and multiple second label assemblies 20 arranged side by side on the second unwinding shaft 21a, creating multiple assembly channels. This allows for simultaneous assembly of multiple finished label assemblies 30, significantly improving assembly efficiency. Furthermore, during the labeling process, the number and spacing of the products 40 to be labeled between the inlet valve 45a and the outlet valve 46a are identical to the number and spacing of the finished label assemblies 30 in each row, creating multiple labeling channels. This allows for simultaneous labeling of multiple products 40, significantly improving labeling efficiency.

[0056] Because the number of labels assembled and applied simultaneously is significantly increased, while maintaining production efficiency for both assembly and labeling, the peeling speed of the finished label assembly 30 can be appropriately reduced, mitigating the risk of label flying caused by excessive peeling speeds. This is particularly true for this combination label, where label flying is more severe due to the doubled thickness and excessive peeling speeds. Therefore, the aforementioned multi-channel design not only maintains labeling efficiency but also reduces the speed of label movement during the peeling process of the finished label assembly 30, thereby reducing the risk of label flying on the finished label 30a.

[0057] The product 40 to be labeled can be, but is not limited to, a vial. The guide rail 41 includes an inner guide rail 41a and an outer guide rail 41b. The conveyor 48a circulates under the guide rail 41. The conveyor 48a can be a conveyor belt or a conveyor chain, such as the vial and pre-filled syringe conveyor chain / belt and power system commonly used in the pharmaceutical packaging equipment industry. This application does not limit this. Figure 10a As shown, the vials are sorted by the bottle unscrambler 50 and then enter the guide rail 41 above the conveyor 48a. Figure 10bAs shown, the bottle unscrambler 50 includes a planar main conveyor chain plate 51a and a side auxiliary conveyor crawler 52a for accommodating bottles. The planar main conveyor chain plate 51a is connected to the planar main conveyor chain plate drive motor 51b, and the side auxiliary conveyor crawler 52a is connected to the side auxiliary conveyor crawler drive motor 52b. The planar main conveyor chain plate drive motor 51b and the side auxiliary conveyor crawler drive motor 52b respectively drive the planar main conveyor chain plate 51a and the side auxiliary conveyor crawler 52a to rotate, and the syringe bottles are transported on the planar main conveyor chain plate 51a and sequentially enter the guide rail 41. The conveying member 48a of the present application can be seamlessly connected with the bottle conveyor line of the packaging production line, and its power control can be switched. It can be controlled by the control system provided by the present application or by the packaging production line control system.

[0058] It should be noted that the frame 1 can be a whole or include two relatively independent parts, namely a first part and a second part. The assembly unit is provided in the first part, and the labeling unit is provided in the second part, so as to facilitate the multi-channel automatic assembly labeling device to be used as an assembly device alone or as a labeling device alone. The bottle unscrambler 50 can also be an independent part, used in conjunction with the assembly unit and the labeling unit of the frame 1. In some embodiments, the finished label 30a is a heat-sensitive label, the first label 10a is an adsorption indication functional label, including a first base film 10b, an isolation diffusion layer, an adsorption material layer, and a functional indication layer arranged in sequence; the second label 20a is a heat-sensitive functional label, including a second base film, a substrate layer carrying a volatile fuel layer, and a volatile dye layer arranged in sequence, or including a second base film, a substrate layer carrying a volatile fuel layer, a volatile dye layer, and a sealing film arranged in sequence.

[0059] The sealing film is an optional film layer. When the volatile dye layer evaporates quickly, a sealing film can be provided to cover the upper surface of the volatile dye layer.

[0060] In this embodiment, the finished label 30a includes a first label 10a as an adsorption indicator functional layer and a second label 20a as a heat-sensitive functional layer. After being attached to a product, it can be used to monitor the heat exposure history of heat-sensitive items during storage and transportation, and indicate whether the heat-sensitive items have become ineffective or deteriorated due to excessive heat exposure. In addition, the multi-channel automatic assembly and labeling equipment can directly assemble the two parts of the label and attach them to the product 40 to be labeled, thereby eliminating the storage and management of the heat-sensitive labels and reducing the risk of heat exposure of the finished label assembly 30 during use. In some embodiments, such as Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 9As shown, the product conveying unit for labeling further includes a positioning device 47a and a positioning drive cylinder 47b. The positioning device 47a is arranged in the outer guide rail 41b, and the positioning drive cylinder 47b is arranged on the conveying platform and connected to the positioning device 47a. The positioning device 47a has a plurality of card slots on the side facing the product 40 to be labeled. The spacing between each card slot is equal to the spacing between two adjacent finished labels 30a in a row. The card slots have the same contour structure as the outer contour of the side of the product 40 to be labeled facing the positioning device 47a. The positioning drive cylinder 47b can drive the positioning device 47a to abut or release the abutment with the product 40 to be labeled.

[0061] In this embodiment, the spacing between the slots of the positioning device 47a is equal to the spacing between adjacent finished labels 30a in each row of finished labels 30a. The positioning device 47a also has a contoured structure that mirrors the outer contour of the product 40 to be labeled. For example, in the case of a bottle, this contoured structure means the slots have a similar curved shape to the bottle. When the positioning drive cylinder 47b drives the positioning device 47a into contact with the product 40 to be labeled, the position of each product 40 to be labeled precisely corresponds to the position of the finished labels 30a, thereby improving labeling accuracy.

[0062] Among them, the forward movement of the positioning device 47a driven by the positioning drive cylinder 47b is synchronized with the forward movement of the feed valve 45a driven by the feed drive cylinder 45b, and the backward movement of the positioning device 47a driven by the positioning drive cylinder 47b is synchronized with the backward movement of the discharge valve 46a driven by the discharge drive cylinder 46b.

[0063] In some embodiments, as Figure 2 、 Figure 9 As shown, the product conveying unit for labeling further includes a stabilizing member 42, which is disposed at the feed end of the conveying member 48a. The stabilizing member 42 is located above the guide rail 41, and its orthographic projection on the guide rail 41 is at least partially located within the guide rail 41. The stabilizing member 42 is located above the inner guide rail 41a or the outer guide rail 41b, and its orthographic projection on the guide rail 41 is at least partially located within the guide rail 41. The stabilizing member 42 is embedded in but does not contact a specific position of the product 40 to be labeled, so as to prevent the product 40 to be labeled from overturning due to impact during transportation.

[0064] In this embodiment, the stabilizing member 42 is located above the guide rail 41, and its orthographic projection on the guide rail 41 is at least partially located within the guide rail 41, that is, the stabilizing member 42 is at least partially embedded in but does not contact a specific position of the product to be labeled 40. Taking the vial as an example, the stabilizing member 42 is at least partially embedded in but does not contact the bottleneck of the vial, to prevent the reverse impact when the feed valve 45a stops the product to be labeled 40 from moving forward from being transmitted to the end product to be labeled 40, causing the product to be labeled 40 to overturn.

[0065] Specifically, the stabilizing member 42 may be a metal strip with a thickness of about 2 mm to 3 mm, which is installed close to the upper surface of the guide rail 41 . For example, the thickness may be 2 mm, 2.5 mm, 3 mm, etc.

[0066] In some embodiments, as Figure 8 As shown, the product conveying unit to be labeled also includes a label pressing wheel 44a and a label pressing drive motor 44b connected to the label pressing wheel 44a. Along the transmission direction of the conveying member 48a, the label pressing wheel 44a is arranged downstream of the discharge valve 46a, and the label pressing drive motor 44b drives the label pressing wheel 44a to roll on the finished product label 30a of the labeled product.

[0067] In this embodiment, the label pressing wheel 44a is driven by the label pressing drive motor 44b to roll on the finished label 30a attached to the product, pressing the finished label 30a onto the product to be labeled 40, thereby improving the bonding strength between the finished label 30a and the product to be labeled 40, and ensuring that the finished label 30a will not automatically or passively separate from the product to be labeled 40 in subsequent processes.

[0068] In some embodiments, as Figure 1 、 Figure 2 As shown, the stripping part also includes a first reeling shaft 11b, a first peeling plate 14, a first traction device 13 and a first guide assembly. The first guide assembly at least includes a first guide shaft 12a and a second guide shaft 12b. The first guide shaft 12a is located between the first unwinding shaft 11a and the first peeling plate 14. The bottom of the first guide shaft 12a is flush with the upper surface of the first peeling plate 14. The second guide shaft 12b is located below the first peeling plate 14, so that the first label assembly 10 is guided by the first guide shaft 12a and transported to the front end of the first peeling plate 14. Under the guidance of the second guide shaft 12b, the first label 10a and the first base film 10b of the first label assembly 10 are separated by the first peeling plate 14. The first traction device 13 is located between the first peeling plate 14 and the first reeling shaft 11b, and is used to clamp and pull the first base film 10b to be stored in the first reeling shaft 11b. The mounting part also includes a second traction device 23 and a second guide assembly. The second guide assembly includes at least a third guide shaft 22a. Along the conveying direction of the first label assembly 10, the third guide shaft 22a is located downstream of the first peeling plate 14, and the vertex of the third guide shaft 22a is flush with the upper surface of the first peeling plate 14, so that the first label 10a can be attached to the second label assembly 20 to form a finished label assembly 30. Along the conveying direction of the second label assembly 20, the second traction device 23 is located downstream of the third guide shaft 22a for clamping and pulling the finished label assembly 30.

[0069] In this embodiment, the first guide assembly is used to guide the direction of the first label assembly 10. The first guide assembly includes at least a first guide shaft 12a and a second guide shaft 12b. The first guide shaft 12a is located between the first unwinding shaft 11a and the first peeling plate 14. The bottom of the first guide shaft 12a is flush with the upper surface of the first peeling plate 14, that is, the tangent direction of the lowest point of the first guide shaft 12a is horizontally flush with the upper surface of the first peeling plate 14, and the left side of the first guide shaft 12a is vertically flush with the right side of the correction shaft of the first longitudinal registration sensor S1. The second guide assembly is used to guide the direction of the second label assembly 20. The second guide assembly includes at least a third guide shaft 22a. Along the conveying direction of the first label assembly 10, the third guide shaft 22a is located downstream of the first peel plate 14. That is, the first label 10a of the first label assembly 10 first passes through the first peel plate 14 and then reaches the third guide shaft 22a. The apex, that is, the highest point, of the third guide shaft 22a is flush with the upper surface of the first peel plate 14, so that the first label 10a can be attached to the upper surface of the second label assembly 20.

[0070] The first label assembly 10 is released by the first unwinding shaft 11a. The first guide shaft 12a then guides the first label assembly 10, ensuring it adheres closely to the surface of the first peeling plate 14. After the first label 10a and the first backing film 10b are peeled off at the edge of the first peeling plate 14, the first label 10a is transferred and bonded to the top surface of the second label assembly 20. The first traction device 13 clamps and pulls the first backing film 10b, transporting it to the first rewinding shaft 11b for storage, completing the continuous peeling of the first label assembly 10 and supplying the first label 10a. The second unwinding shaft 21a releases the second label assembly 20 and receives the first label 10a downstream of the first peeling plate 14, bonding it to the top surface of the second label assembly 20. The second traction device 23 clamps and pulls the second label assembly 20 downstream, adjusting the transfer speed of the two devices to ensure precise attachment of the first label 10a to the top surface of the second label assembly 20.

[0071] In order to ensure a smooth transition of the first label 10a to the upper surface of the second label assembly 20, the gap between the first peeling plate 14 and the third guide shaft 22a is less than or equal to 5 mm, so that the first label 10a can be smoothly transferred to the upper surface of the second label assembly 20 by alternately adhering to the first base film 10b and the second label assembly 20 during the peeling process.

[0072] Specifically, if Figure 1 、 Figure 2As shown, the first traction device 13 includes a second drive motor 13a, a first coaxial roller 13d connected to the main shaft of the second drive motor 13a, a first driven roller 13b and a first pressure roller 13c abutting each other, and the first base film 10b is located between the first driven roller 13b and the first pressure roller 13c. The second drive motor 13a drives the first coaxial roller 13d to rotate, and drives the first driven roller 13b and the first pressure roller 13c to rotate; the second traction device 23 includes a third drive motor 23a, a second coaxial roller 23d connected to the main shaft of the third drive motor 23a, a second driven roller 23b and a second pressure roller 23c abutting each other, and the finished product is marked. The label assembly 30 is located between the second driven roller 23b and the second pressure roller 23c. The third drive motor 23a drives the second coaxial roller 23d to rotate, and drives the second driven roller 23b and the second pressure roller 23c to rotate. When the finished label assembly 30 passes through the second driven roller 23b and the second pressure roller 23c, it is transported downstream by relying on the friction between the finished label assembly 30 and the second driven roller 23b and the second pressure roller 23c. By controlling the gap between the second driven roller 23b and the second pressure roller 23c, the finished label assembly 30 can also be pressed, so that the first label 10a is firmly attached to the second label assembly 20.

[0073] The second drive motor 13a and the third drive motor 23a may be stepper motors, which facilitate control of their pace so as to match the conveying speeds of the first label assembly 10 and the second label assembly 20 driven by the second drive motor 13a and the third drive motor 23a, respectively. The first pressure roller 13c and the second pressure roller 23c may be rubber rollers.

[0074] It should also be noted that Figure 1 The second drive motor 13a and the third drive motor 23a are located in the inner cabinet of the first coaxial roller 13d and the second coaxial roller 23d. Figure 1 The second drive motor 13a and the third drive motor 23a cannot be seen from the angle.

[0075] like Figure 5As shown, the flyer device includes a third traction device 33, a second take-up shaft 31b, a third guide assembly, a pressing plate 34a, a pressing drive cylinder 34b, a second stripping plate 38, a fifth drive motor 36, a first slide rail 37, a material guide platform 26 and a label feeding positioner S4; the third traction device 33 is located between the second stripping plate 38 and the second take-up shaft 31b, and is used to clamp and pull the finished base film 30b to be stored on the second take-up shaft 31b. The third traction device 33 includes a fourth drive motor 33a, a third driven roller 33b connected to the main shaft of the fourth drive motor 33a by a crawler belt, and a third pressure roller 33c abutting against the third driven roller 33b. The finished base film 30b is located between the third driven roller 33b and the third pressure roller 33c. The fourth drive motor 33a drives the third driven roller 33b and drives the third pressure roller 33c to rotate. The pressing plate 34a is connected to the pressing drive cylinder 34b, and the fifth drive motor 36 is connected to the second The peeling plate 38 is connected, and the feeder device controls the pressing drive cylinder 34b to drive the pressing plate 34a to move upward or downward according to the information of the label feeding positioner S4; the third guide assembly includes at least a fourth guide shaft 32a and a fifth guide shaft 32b, the fourth guide shaft 32a is located upstream of the guide platform 26, and the vertex of the fourth guide shaft 32a is flush with the upper surface of the guide platform 26, and the fifth guide shaft 32b is located below the second peeling plate 38, so that the finished label assembly 30 is guided by the fourth guide shaft 32a and transported to the front end of the second peeling plate 38, and under the guidance of the fifth guide shaft 32b, the finished label 30a and the finished base film 30b of the finished label assembly 30 are separated by the second peeling plate 38; the second peeling plate 38 is arranged on the first slide rail 37 and is connected to the fifth drive motor 36, and the fifth drive motor 36 drives the second peeling plate 38 to reciprocate toward or away from the product 40 to be labeled according to a predetermined stroke.

[0076] In this embodiment, a fifth drive motor 36 is used to drive the second stripper plate 38 to reciprocate above the product 40 to be labeled. Specifically, the second stripper plate 38 can be mounted on a first slide rail 37. The fifth drive motor 36 drives the second stripper plate 38 to reciprocate along the first slide rail 37 according to a predetermined stroke set by the feeder control system. The predetermined reciprocating stroke is determined based on the size of the finished labels 30a and the longitudinal spacing between adjacent rows of finished labels 30a. Optionally, the finished labels 30a may have a diameter of 11-12 mm and a longitudinal spacing of 12-18 mm. For example, the finished labels 30a may have a diameter of 11 mm and a longitudinal spacing of 12.12 mm. A range of vertical adjustment is maintained between the fixed position of the feeder device and the bottom of the frame 1, allowing precise adjustment of the distance of the second stripper plate 38 above the product 40 to ensure smooth labeling. When the second peeling plate 38 is at the remote position set by its reciprocating motion, the remote position is close to the position of the product to be labeled 40, and the assembled finished label assembly 30 realizes the peeling of the finished label 30a and the finished base film 30b at the cutting edge of the second peeling plate 38, and extends forward in the air. The label feeding positioner S4 is used to control the extended distance of the finished label 30a. When the finished label 30a and the product to be labeled 40 are in place, the lower label driving cylinder 43b is first triggered to drive the lower label plate 43a downward, pressing the suspended part of the finished label 30a to the upper surface of the product to be labeled 40. When the product to be labeled 40 is a vial, the suspended part of the finished label 30a is pressed to On the cap of the syringe bottle, when the second label stripping plate 38 retreats to the short-range position set by its reciprocating motion, the short-range position is far away from the position of the product to be labeled 40, and the finished label 30a is completely transferred to the product to be labeled 40, completing a set of labeling actions. At this time, the labeling driving cylinder 43b is triggered to drive the labeling plate 43a to reset upward, and at the same time, a signal is sent to the discharge driving cylinder 46b, triggering the discharge driving cylinder 46b to drive the discharge valve 46a to withdraw from the guide rail 41. The conveying member 48a rotates continuously under the drive of the first drive motor 48b, starting the emptying action of the labeled products, and at the same time driving the second label stripping plate 38 to reset and the next row of finished labels 30a to be in place.

[0077] The signature locator S4 may be a cursor locator.

[0078] In addition, it should be noted that if Figures 1-4 As shown, the multi-channel automatic assembly labeling equipment of the dual-label component can also include a third unwinding shaft 31a, a third rewinding shaft 21b and a fourth rewinding shaft 21c. The third unwinding shaft 31a is arranged upstream of the feeder device in the second part of the frame and serves as the unwinding shaft when the labeling unit is used alone; the third rewinding shaft 21b and the fourth rewinding shaft 21c are respectively arranged at the upper and lower positions of the first part of the frame, and can be used as rewinding shafts for the finished label assembly 30 when the assembly unit is used alone.

[0079] In some embodiments, as Figure 9 As shown, the multi-channel automatic assembly and labeling equipment of the dual-label component also includes a control system, which includes an assembly control system, a feeder control system and a labeling control system. The second drive motor 13a is electrically connected to the assembly control system, and the assembly control system controls the working state of the second drive motor 13a. The third drive motor 23a is electrically connected to the assembly control system, and the assembly control system controls the working state of the third drive motor 23a. The fourth drive motor 33a is electrically connected to the feeder control system, and the feeder control system controls the working state of the fourth drive motor 33a; the third traction device 33, the second winding shaft 31b, the pressing drive cylinder 34b, the fifth drive motor 36 and the label delivery positioner S4 are electrically connected to the feeder control system, and the feeder control system sends control instructions to the pressing drive cylinder 34b and the fifth drive motor 36 according to the information of the label delivery positioner S4, thereby controlling the working state of the pressing drive cylinder 34b and the second label peeling plate 38; the labeling control system also includes a control system for the product to be labeled 40 The multi-channel automatic labeling system for dual-label assemblies includes an infeed optical fiber counter S5 and an outfeed optical fiber counter S6, respectively positioned upstream and downstream of a positioning device 47a along the transport direction of the product 40 to be labeled. The product 40 control system, based on information from the infeed optical fiber counter S5 and the outfeed optical fiber counter S6, sends instructions to the infeed drive cylinder 45b and the outfeed drive cylinder 46b, thereby controlling the operating states of the infeed drive cylinder 45b and the outfeed drive cylinder 46b. The labeling control system is electrically connected to the infeed optical fiber counter S5 and, based on information from the infeed optical fiber counter S5, sends instructions to the labeling drive cylinder 43b, thereby controlling the operating state of the labeling drive cylinder 43b.

[0080] The assembly control system can control the operating states of the second drive motor 13a and the third drive motor 23a, thereby automatically completing the positioning, transfer, and registration assembly of the first label 10a on the first label assembly 10 to the second label assembly 20. The feeder control system is electrically connected to the label feed positioner S4. When the fifth drive motor 36 drives the second label peeling plate 38 to the remote position within the predetermined travel range, the feeder control system controls the pressing drive cylinder 34b to move upward, allowing the finished label assembly 30 to continue to be conveyed downstream. Based on the position information of the label feed positioner S4, the feeder control system sends a command to the pressing drive cylinder 34b to control the pressing drive cylinder 34b to move downward, causing the pressing plate 34a to press the finished label assembly 30, completing the positioning and conveying of the finished label assembly 30. When the feeder control system sends a command to the fifth drive motor 36 to drive the second label peeling plate 38 to the near-range position within the predetermined travel range, it simultaneously sends a command to the third traction device 33 to traction the finished base film 30b, completely separating the finished label 30a from the finished base film 30b.

[0081] The labeling control system is electrically connected to the input optical fiber counter S5 and the output optical fiber counter S6. The labeling control system sends an instruction to the lower label driving cylinder 43b according to the information of the input optical fiber counter S5, thereby controlling the lower label driving cylinder 43b to drive the lower label plate 43a to press the finished label 30a partially onto the product 40 to be labeled, and then sends an instruction to the fifth drive motor 36 to drive the second label stripping plate 38 to withdraw to the short-range position of the predetermined stroke. At the same time, the third traction device 33 pulls the finished base film 30b, so that the finished label 30a is completely peeled off from the finished base film 30b, completing a round of labeling action; then the lower label control system sends an instruction to the lower label driving cylinder 43b to drive the lower label plate 43a to reset upward, and sends an instruction to the output drive cylinder 46b. b drives the discharge valve 46a to withdraw from the outer guide rail 41b, and the labeled products are cleared out, that is, the labeled products are completely conveyed out along the guide rail 41 to make room for labeling for the subsequent products 40 to be labeled to enter; when the discharge optical fiber counter S6 detects that the labeled products are completely cleared out or the set number is reached, the labeling control system sends an instruction to the feed drive cylinder 45b, and the feed drive cylinder 45b drives the feed valve 45a to withdraw from the outer guide rail 41b, allowing the products 40 to be labeled to enter; when the discharge optical fiber counter S6 detects that the labeled products are completely cleared out, the labeling control system sends an instruction to the discharge drive cylinder 46b, and the discharge drive cylinder 46b drives the discharge valve 46a to extend into the inner side of the outer guide rail 41b, blocking the products 40 to be labeled that are in place, and entering the next round of labeling action.

[0082] The control system for the product to be labeled 40 is connected to the feeder control system and can operate in both manual and automatic modes. In manual mode, each action can be manually operated for equipment debugging and optimization.

[0083] In the automatic mode, the control system for the product 40 to be labeled can provide different program modes to control the conveying and labeling process of the product 40 to be labeled by counting or delaying.

[0084] In some embodiments, the control system for the products 40 to be labeled controls the operating states of the feed drive cylinder 45b and the discharge drive cylinder 46b by counting or delaying. One program mode is to start the loading of the products 40 to be labeled after the bottles have been discharged by counting or delaying. Another program mode is to start the loading of the products 40 to be labeled after the counted number of discharged products 40 has reached a set number, or to start the loading of the products 40 to be labeled after all the labeled products have been discharged by delaying the feed.

[0085] In some embodiments, as Figure 2 、 Figure 5As shown, the labeling unit also includes a pressing plate 35, which is located above the second peeling plate 38 and extends from the cutting edge side of the second peeling plate 38 to the side away from the cutting edge. The finished label assembly 30 is located between the pressing plate 35 and the second peeling plate 38. The pressing plate 35 presses the end of the finished label 30a close to the cutting edge to prevent the finished label 30a from sagging.

[0086] In this embodiment, the pressing plate 35 above the edge of the second peeling plate 38 is used to press the tail of the suspended front finished label 30a to prevent the finished label 30a from sagging, so as not to interfere with the delivery of the product 40 to be labeled.

[0087] In some embodiments, as Figure 2-Figure 4 As shown, the multi-channel automatic assembly and labeling equipment for dual label assemblies also includes a web length control sensor S3 and a first tension rod 24. The web length control sensor S3 is mounted on the frame 1. The first tension rod 24 is placed on the finished label assembly 30 and located between the second driven roller 23b and the fourth guide shaft 32a. Rings with a larger diameter than the first tension rod 24 are provided at both ends of the first tension rod 24. The first tension rod 24 continuously rises under the traction of the third traction device 33. The web length control sensor S3 can sense the position of the first tension rod 24 to obtain web length information. The web length control sensor S3 is electrically connected to the assembly control system. When the web length control sensor S3 detects that the web length is insufficient, it sends a signal to the assembly control system, which then controls the assembly unit to assemble the finished label assembly 30 and release the finished label assembly 30 of the set length.

[0088] In this embodiment, when the length of the material between the second driven roller 23b and the fourth guide shaft 32a falls below a set value, a signal is transmitted to the assembly control system, triggering the assembly unit to initiate assembly and deliver the material to the preset length. The first tension rod 24 is used to straighten the finished label assembly 30 to ensure the proper functioning of the material length control sensor S3. A ring with a larger diameter than the first tension rod 24 is used at each end of the first tension rod 24 to prevent it from falling off the finished label assembly 30.

[0089] Optionally, the first tension rod 24 may be a metal tension rod. The metal tension rod has a higher density and a higher weight under the same volume, and can better play the role of straightening the finished label assembly 30 .

[0090] In some embodiments, as Figure 2-Figure 4As shown, a sixth guide shaft 32c and a seventh guide shaft 32d are provided between the second driven roller 23b and the fourth guide shaft 32a, which are arranged in sequence on the frame 1 along the transmission direction of the product 40 to be labeled. The sixth guide shaft 32c and the seventh guide shaft 32d are of the same height and are both located above the material length control sensor S3. The first tension rod 24 is located between the sixth guide shaft 32c and the seventh guide shaft 32d. An eighth guide shaft 32f is provided between the seventh guide shaft 32d and the fourth guide shaft 32a. A second tension rod 25 is provided between the eighth guide shaft 32f and the fourth guide shaft 32a. The second tension rod 25 is installed on the second slide rail of the feeder device. In this embodiment, the sixth and seventh guide shafts 32c and 32d are added between the second driven roller 23b and the fourth guide shaft 32a. This increases the length of the finished label assembly 30, which is connected to the flexible connection between the second driven roller 23b and the fourth guide shaft 32a, and broadens the tolerance range between the assembly unit and the labeling unit, thereby improving the operating stability of the device. The sixth and seventh guide shafts 32c and 32d are located above the material length control sensor S3, conveniently detecting the length of the material between the sixth and seventh guide shafts 32c and 32d. An eighth guide shaft 32f and a second tension rod 25 are added upstream of the fourth guide shaft 32a in the second section of the frame. When the labeling system in the second section of the frame is used alone, these guide shafts straighten the finished label assembly 30 before it enters the guide platform 26. The second tension rod 25 moves up and down along a second guide rail (not shown), a slot in the feeder assembly that defines the movement trajectory of the second tension rod 25.

[0091] Alternatively, the second tension rod 25 is placed directly on the upper surface of the finished label assembly 30, and both ends of the second tension rod 25 are sleeved with rings with a diameter larger than that of the second tension rod 25 to prevent the second tension rod 25 from falling off the finished label assembly 30. Specifically, the second tension rod 25 can be a metal tension rod.

[0092] It should be noted that the eighth guide shaft 32f is a standard feature of the feeder device and is required when the second part is used alone, but is optional when the first part and the second part are used together. Figure 3 and Figure 4 It is only a structural diagram of the assembly unit and labeling unit, and does not include the feeder device.

[0093] In some embodiments, as Figures 1-4 As shown, the multi-channel automatic assembly and labeling equipment for dual label components also includes at least a first lateral registration device R1 and a second lateral registration device R2. The first lateral registration device R1 is arranged between the first unwinding shaft 11a and the first guide shaft 12a, and the second lateral registration device R2 is arranged between the second unwinding shaft 21a and the third guide shaft 22a to monitor the lateral position deviation of the first label component 10 and the second label component 20 respectively.

[0094] By setting up a first transverse registration device R1 and a second transverse registration device R2, the transverse positions of the first label assembly 10 and the second label assembly 20 along the axial direction of the first unwinding shaft 11a and the second unwinding shaft 21a are controlled respectively, so that during the conveying process of the first label assembly 10 and the second label assembly 20, the transverse positions of the first label assembly 10 and the second label assembly 20 are always kept aligned, thereby ensuring the transverse positioning accuracy of the finished label 30a of the finished label assembly 30 formed by bonding.

[0095] Specifically, the first and second transverse registration devices R1 and R2 are deflection controllers. Deflection controllers are devices used to correct for material misalignment during transport. They consist of a mechanical structure, a control system, and sensors. The mechanical structure primarily corrects the position of the transported material, the control system controls the movement of the mechanical structure, and the sensors detect the material's position.

[0096] Taking the skew correction control of the first label assembly 10 as an example, the skew correction controller in this application can use a photoelectric sensor to detect the position of the edge or line of the first label assembly 10, thereby generating an edge or line position deviation signal. This position deviation signal is then transmitted to the control system for logical calculation, and a control signal is sent to the mechanical structure to drive the mechanical structure to correct the serpentine deviation of the first label assembly 10 during operation, ensuring that the lateral position of the first label 10a remains unchanged during the conveyance of the first label assembly 10.

[0097] Alternatively, the correction controller only includes a photoelectric sensor and a control system, and manually corrects the position deviation of the first label assembly 10 so that the lateral position of the first label 10a remains unchanged during the conveyance of the first label assembly 10.

[0098] In some embodiments, as Figure 2-Figure 4 As shown, a ninth guide shaft 12c is provided between the first transverse registration device R1 and the first unwinding shaft 11a, and the ninth guide shaft 12c is located below the first unwinding shaft 11a and the first transverse registration device R1. A tenth guide shaft 22b is provided between the second transverse registration device R2 and the second unwinding shaft 21a, and the tenth guide shaft 22b is located below the second unwinding shaft 21a and the second transverse registration device R2. Specifically, the ninth guide shaft 12c can be located below the first unwinding shaft 11a and the upstream of the first transverse registration device R1, and the tenth guide shaft 22b can be located below the second unwinding shaft 21a and the upstream of the second transverse registration device R2.

[0099] In this embodiment, the ninth guide shaft 12c plays a role in positioning and guiding the first label assembly 10 before it enters the first transverse registration device R1, so that the first transverse registration device R1 can correct the serpentine deviation of the first label assembly 10 during the transportation process through its mechanical mechanism; the tenth guide shaft 22b plays a role in changing direction and guiding the second label assembly 20 before it enters the second transverse registration device R2, so that the second transverse registration device R2 can correct the serpentine deviation of the second label assembly 20 during the transportation process through its mechanical mechanism.

[0100] In some embodiments, as Figure 2-Figure 4 As shown, the multi-channel automatic assembly and labeling equipment for dual label components also includes at least a first longitudinal registration sensor S1 and a second longitudinal registration sensor S2. The first longitudinal registration sensor S1 is arranged between the first guide shaft 12a and the first peeling plate 14, and the second longitudinal registration sensor S2 is arranged between the third guide shaft 22a and the second traction device 23 to monitor the longitudinal relative position of the longitudinal registration cursor printed on the first label component 10 and the longitudinal registration cursor printed on the second label component 20; the first longitudinal registration sensor S1 and the second longitudinal registration sensor S2 are electrically connected to the assembly control system respectively, and the assembly control system performs logical operations based on the longitudinal registration cursor position information printed on the first label component 10 provided by the first longitudinal registration sensor S1 and the longitudinal registration cursor position information printed on the second label component 20 provided by the second longitudinal registration sensor S2, and provides the second drive motor 13a with the tracking compensation direction and compensation amount.

[0101] In this embodiment, the first longitudinal registration sensor S1 and the second longitudinal registration sensor S2 can realize automatic alignment of the first label assembly 10 and the second label assembly 20 along the conveying direction, thereby ensuring the longitudinal positioning accuracy of the finished label 30a on the finished label assembly 30 formed by bonding. In combination with the first transverse registration device R1 and the second transverse registration device R2, the first label 10a and the second label 20a can be automatically aligned in a direction perpendicular to the conveying direction, thereby ensuring the transverse positioning accuracy of the finished label 30a on the finished label assembly 30 formed by bonding, thereby jointly ensuring the positioning accuracy of the first label 10a when it is bonded to the second label assembly 20.

[0102] like Figure 2-Figure 4 As shown, the right side of the correction axis of the first longitudinal registration sensor S1 is vertically flush with the left side of the first guide shaft 12a, which facilitates the photoelectric sensor of the first transverse registration device R1 to read the serpentine deviation of the first label component 10 during the transportation process and send a signal to the mechanical mechanism of the first transverse registration device R1 to correct the serpentine deviation of the first label component 10 during the transportation process.

[0103] An eleventh guide shaft 22c is located between the second transverse register device R2 and the third guide shaft 22a, positioned below and to the right of the second transverse register device R2. This eleventh guide shaft 22c serves to redirect and guide the second label assembly 20 as it leaves the second transverse register device R2. The right side of the deflection correction shaft of the second longitudinal register sensor S2 is aligned vertically with the left side of the eleventh guide shaft 22c, enabling the photoelectric sensor of the second transverse register device R2 to detect any serpentine deviation of the second label assembly 20 during transport and send a signal to the mechanical mechanism of the second transverse register device R2 to correct the serpentine deviation. A twelfth guide shaft 32e is also located between the fifth guide shaft 32b and the third traction device 33. This shaft increases the degree of tension applied by the third traction device 33 to the finished base film 30b.

[0104] Optionally, the first longitudinal registration sensor S1 and the second longitudinal registration sensor S2 are print cursor readers. The two print cursor readers identify the relative positions of the longitudinal registration cursor printed on the first label assembly 10 and the second label assembly 20, and provide tracking compensation direction and compensation amount to the second drive motor 13a, thereby achieving automatic longitudinal registration control.

[0105] In order to more clearly illustrate the dual-component multi-channel automatic assembly and labeling equipment of the embodiment of the present application, the following four specific embodiments are described in detail.

[0106] Example 1 is a control mode for counting and controlling the removal of labeled bottles and the entry of bottles to be labeled:

[0107] The structural diagram of the dual-component multi-channel automatic assembly labeling equipment is as follows Figures 1-4The second drive motor 13a, the third drive motor 23a and the fourth drive motor 33a use stepper motors or servo motors to drive the combined rubber rollers to transport the first label assembly 10, the second label assembly 20 and the finished label assembly 30 through gears or crawler transmission: the first label assembly 10 is released from the first tension-controlled unwinding shaft 11a, passes through the ninth guide shaft 12c, the first transverse registration device R1, the first guide shaft 12a, the first peeling plate 14, the second guide shaft 12b and the first traction device 13, and is fixed to the first tension-controlled rewinding shaft 11b; the second label assembly 20 is released from the second tension-controlled unwinding shaft 21a, passes through the tenth guide shaft 22b, the second transverse registration device R2, the eleventh guide shaft 22c, the third The guide shaft 22a, second traction device 23, web length control sensor S3, second stripper plate 38, and third traction device 33 are then secured to the tension-controlled second reel 31b. A first longitudinal registration sensor S1 and a second longitudinal registration sensor S2 are installed at appropriate locations along the conveyance path of the first and second label assemblies 10 and 20, respectively. These sensors read the longitudinal relative positions of the longitudinal registration cursors printed on the first and second label assemblies 10 and 20, and provide the tracking compensation direction and amount to the second drive motor 13a, achieving automatic longitudinal registration control. Automatic transverse registration is achieved by manually adjusting the detection positions of the first and second transverse registration devices R1 and R2. When the labeling unit consumes enough web length, causing the web length control sensor S3 to signal insufficient web length, the assembly control system activates the first and second traction devices 13 and 23 to begin label assembly. Assembly automatically stops when the set web length is reached, awaiting the next signal from the web length control sensor S3.

[0108] The second peeling plate 38 is mounted on the first slide rail 37, and a stepper motor or servo motor is used to drive the second peeling plate 38 to reciprocate along the first slide rail 37 system. The stroke of the reciprocating motion is set according to the size and longitudinal spacing of the finished label 30a. In this embodiment, the diameter of the finished label 30a is 11mm, and the longitudinal spacing is 12.12mm. When the second peeling plate 38 is at the remote position set for its reciprocating motion, the assembled finished label assembly 30 is peeled off from the cutting edge of the second peeling plate 38 and the finished base film 30b and suspended forward. The position of the suspended label is controlled by the label feeding positioner S4, and the pressing plate 35 above the cutting edge of the second peeling plate 38 is used to press the tail of the suspended finished label 30a to prevent the finished label 30a from sagging. When the finished label 30a and the product 40 to be labeled are in place, the lower label driving cylinder 43b is triggered first to drive the lower label plate 43a downward, pressing the finished label 30 The suspended part of a is moved to the upper surface of the product 40 to be labeled, such as the bottle cap, and then the second label stripping plate 38 is withdrawn to the short-range position set by its reciprocating motion. The finished label 30a is completely transferred to the bottle cap. At this time, the label lowering drive cylinder 43b is triggered to drive the lower label plate 43a to reset upward, completing a set of label lowering actions. At the same time, a signal is sent to the labeling control system to trigger the discharge drive cylinder 46b to retract the discharge valve 46a, starting the emptying action of the labeled products. At the same time, the feeder system drives the second label stripping plate 38 to reset and the next row of finished labels 30a is in place.

[0109] On the conveyor 48a for the labeling products 40, an infeed optical fiber counter S5 and an outfeed optical fiber counter S6 are installed at appropriate locations corresponding to the first and last two finished labels 30a in a row. An infeed valve 45a and its infeed drive cylinder 45b, and an outfeed valve 46a and its outfeed drive cylinder 46b are also installed. A positioning device 47a and its positioning drive cylinder 47b are installed between the infeed and outfeed valves 45a and 46a. The lateral spacing of the finished labels 30a corresponds to the maximum outer diameter of the labeling products 40. In this embodiment, the labeling products 40 are vials with an outer diameter of 16 mm. Therefore, the lateral spacing of the finished labels 30a is 16 mm. Each row contains 11 finished labels 30a, corresponding to 11 positioned vials. The vials are capped with an aluminum-plastic cap with a 0.3-0.5 mm high edging.

[0110] In this embodiment, a stabilizer 42 is installed just above the inner guide rail 41a of the bottle. Specifically, the stabilizer 42 is a metal strip with a thickness of 2 mm. After the position of the metal strip is optimized, it can prevent the reverse impact when the bottle stops suddenly from being transmitted to the end bottle, causing the end bottle to overturn.

[0111] The control process of the multi-channel automatic assembly labeling equipment in this embodiment is as follows: Figure 11As shown in the figure, after the equipment control system is powered on, the discharge drive cylinder 46b drives the discharge valve 46a into the bottle blocking position, the inlet drive cylinder 45b drives the inlet valve 45a backward, the first drive motor 48b is activated to transport the bottles, the label pressing drive motor 44b is activated to rotate the label pressing wheel 44a, and the inlet optical fiber counter S5 begins to read and count the bottles in place. When the inlet optical fiber counter S5 reaches 11 (11 is the total number N of finished labels 30a in a row), the labeling control system sends a signal to synchronously trigger the inlet drive cylinder 45b and the positioning drive cylinder 47b to drive the inlet valve 45a and the positioning device 47a forward and out of position, respectively. At the same time, when a row of 11 finished labels 30a is in place, the lower label cylinder drives the lower label plate 43a downward, and the fifth drive motor 36 drives the second label stripping plate 38 backward, transferring the finished labels 30a to the bottle caps. Subsequently, the labeling control system sends a signal to trigger the label lowering drive cylinder 43b to drive the label lower plate 43a upward and reset, and simultaneously triggers the fifth drive motor 36 to drive the second label stripping plate 38 to reset and deliver the label into position. The discharge drive cylinder 46b and the positioning drive cylinder 47b are synchronously triggered to drive the discharge valve 46a and the positioning device 47a to retreat, respectively, to start clearing the bottles. The discharge optical fiber counter S6 reads the labeled bottles and counts them. When the discharge optical fiber counter S6 reaches 11, the labeling control system sends a signal to start triggering the discharge drive cylinder 46b to drive the discharge valve 46a forward and into the bottle blocking position. The infeed drive cylinder 45b drives the infeed valve 45a to retreat. When the label bottles begin to enter their positions, the infeed optical fiber counter S5 begins to read the bottles in position and counts them, entering the next cycle. When the discharged bottles pass the label pressing wheel 44a, the finished labels 30a are pressed onto the bottle caps by the label pressing wheel 44a.

[0112] In this embodiment, the control element used can allow the conveyor 48a of the product 40 to be labeled to clear the bottle within 0.75 seconds, and then drive the bottle into position within 0.75 seconds. At the same time, the feeder system completes the delivery of the label into position within these two time periods, and completes the coordinated peeling and respective reset of the lower label plate 43a and the second label peeling plate 38 within 0.5 seconds. One working cycle can be controlled within 2.0 seconds, and the labeling rate can reach 330 pieces / bottle per minute.

[0113] Example 2 is a control mode in which bottles to be labeled are placed in position after the number of bottles discharged is set by counting control:

[0114] In this embodiment, the structure of the dual-component multi-channel automatic assembly labeling equipment, the specifications of the product to be labeled 40 and the finished label 30a are the same as those in Example 1, that is, the product to be labeled 40 is also a vial, and the control process is as follows: Figure 12As shown. After the control system is powered on and started, the discharging drive cylinder 46b drives the discharging valve 46a to enter the position where the bottle stops, the feeding drive cylinder 45b drives the feeding valve 45a to retract, the first driving motor 48b is started to convey the bottles, the pressing label drive motor 44b is started to drive the pressing label wheel 44a to rotate, and the feeding optical fiber counter S5 starts to identify and count the bottles in place. When the count of the feeding optical fiber counter S5 reaches 11, the labeling control system sends a signal to synchronously trigger the feeding drive cylinder 45b and the positioning drive cylinder 47b to drive the feeding valve 45a and the positioning device 47a to move forward and enter the position respectively. At the same time, when a total of N = 11 finished product labels 30a in a row reach the position, it triggers the lower label drive cylinder 43b to drive the lower label plate 43a to move downward, and the fifth driving motor 36 drives the second label stripping plate 38 to retract, and the finished product labels 30a are transferred to the bottle cap. Subsequently, the labeling control system sends a signal to trigger the lower label drive cylinder 43b to drive the lower label plate 43a to move upward and reset, at the same time triggers the fifth driving motor 36 to drive the second label stripping plate 38 to reset and the label feeding to reach the position, synchronously triggers the discharging drive cylinder 46b and the positioning drive cylinder 47b to drive the discharging valve 46a and the positioning device 47a to retract respectively, and starts to clear the bottles. The discharging optical fiber counter S6 identifies and counts the labeled bottles; when the count of the discharging optical fiber counter S6 reaches n = 3 (n < N), the labeling control system sends a signal to trigger the feeding drive cylinder 45b to drive the feeding valve 45a to retract. When the bottles to be labeled start to enter the position, the feeding optical fiber counter S5 starts to identify and count the bottles in place; when the count of the discharging optical fiber counter S6 reaches 11, the labeling control system sends a signal to trigger the discharging drive cylinder 46b to drive the discharging valve 46a to move forward and enter the position where the bottle stops. When the count of the feeding optical fiber counter S5 reaches 11, it enters the next cycle. When the discharged bottle passes through the pressing label wheel 44a, the finished product label 30a is pressed onto the bottle cap by the pressing label wheel 44a.

[0115] In this embodiment, the control elements used can allow the conveying part 48a of the product 40 to be labeled to clear the bottles and drive the bottles into the position successively within 1.0 second, and at the same time, the flying head system completes the label feeding and reaching the position within this time period. It can complete the coordinated label stripping and respective resetting of the lower label plate 43a and the second label stripping plate 38 within 0.5 second. A working cycle can be controlled within 1.6 seconds, and 400 labels can be applied per minute per bottle.

[0116] Embodiment 3 is a control mode for delaying the entry of the bottles to be labeled after clearing the bottles:

[0117] In this embodiment, the structure of the dual-component multi-channel automatic assembly and labeling device, the bottle and label specifications are the same as those in Embodiment 1, and the control process is as Figure 13As shown. After the control system is powered on, the discharge drive cylinder 46b drives the discharge valve 46a to the bottle stop position, the inlet drive cylinder 45b drives the inlet valve 45a backward, the first drive motor 48b is activated to transport the bottles, the label pressing drive motor 44b is activated to rotate the label pressing wheel 44a, and the inlet optical fiber counter S5 begins to read and count the bottles in place. When the inlet optical fiber counter S5 reaches 11, the labeling control system sends a signal to synchronously trigger the inlet drive cylinder 45b and the positioning drive cylinder 47b to respectively drive the inlet valve 45a and the positioning device 47a forward and out of position. Simultaneously, when a row of 11 finished labels 30a is in place, the lower label drive cylinder 43b is triggered to drive the lower label plate 43a downward, and the second drive motor drives the second label stripping plate 38 backward, transferring the finished labels 30a to the bottle caps. The labeling control system then sends a signal to trigger the label lowering drive cylinder 43b to drive the label lowering plate 43a upward and reset, and simultaneously triggers the fifth drive motor 36 to drive the second label stripping plate 38 to reset and deliver the label into position, and simultaneously triggers the discharge drive cylinder 46b and the positioning drive cylinder 47b to respectively drive the discharge valve 46a and the positioning device 47a to retract; after the bottle is cleared within the set delay range, the labeling control system sends a signal to trigger the discharge drive cylinder 46b to drive the discharge valve 46a forward to the bottle stop position, and the infeed drive cylinder 45b to drive the infeed valve 45a backward, and when the labeling bottle begins to enter the position, the infeed optical fiber counter S5 begins to read the bottle in place and count, and enter the next cycle. When the discharged bottle passes the label pressing wheel 44a, the finished label 30a is pressed onto the bottle cap by the label pressing wheel 44a.

[0118] In this embodiment, the control element used can allow the conveyor 48a of the product 40 to be labeled to clear the bottle within 0.75 seconds, and then drive the bottle into position within 0.75 seconds. At the same time, the feeder system completes the delivery of the label into position within these two time periods, and completes the coordinated peeling and respective reset of the lower label plate 43a and the second label peeling plate 38 within 0.5 seconds. One working cycle can be controlled within 2.0 seconds, and the labeling rate can reach 330 pieces / bottle per minute.

[0119] Example 4 is a control mode in which the bottles to be labeled are placed in position after the number of bottles discharged is set by delay control:

[0120] In this embodiment, the structure, bottle and label specifications of the dual-component multi-channel automatic assembly labeling equipment are the same as those in Example 1. The control process is as follows: Figure 14As shown. After the control system is powered on, the discharge drive cylinder 46b drives the discharge valve 46a to the bottle stop position, the inlet drive cylinder 45b drives the inlet valve 45a backward, the first drive motor 48b is activated to transport the bottles, the label pressing drive motor 44b is activated to rotate the label pressing wheel 44a, and the inlet optical fiber counter S5 begins to read the bottles in place and count them. When the inlet optical fiber counter S5 reaches 11, the labeling control system sends a signal to synchronously trigger the inlet drive cylinder 45b and the positioning drive cylinder 47b to drive the inlet valve 45a and the positioning device 47a forward and out of position, respectively. Simultaneously, when a row of 11 finished labels 30a is in place, the lower label drive cylinder 43b is triggered to drive the lower label plate 43a downward, and the fifth drive motor 36 drives the second label stripping plate 38 backward, transferring the finished labels 30a to the bottle caps. The labeling control system then sends a signal to trigger the label lowering drive cylinder 43b to drive the label lowering plate 43a upward and reset, and simultaneously triggers the fifth drive motor 36 to drive the second label stripping plate 38 to reset and deliver the label into position, and simultaneously triggers the discharge drive cylinder 46b and the positioning drive cylinder 47b to respectively drive the discharge valve 46a and the positioning device 47a to retract. After some bottles are discharged within the set feeding delay range, the labeling control system sends a signal to trigger the feeding drive cylinder 45b to drive the feeding valve 45a to retract. When the labeling bottles begin to enter the position, the feeding optical fiber counter S5 begins to read and count the bottles in place. After the bottles are discharged within the set feeding delay range, the control system sends a signal to trigger the discharging drive cylinder 46b to drive the discharging valve 46a forward to the bottle stop position. When the feeding optical fiber counter S5 reaches 11, the next cycle begins. When the discharged bottle passes the label pressing wheel 44a, the finished label 30a is pressed onto the bottle cap by the label pressing wheel 44a.

[0121] In this embodiment, the control element used can allow the conveyor 48a of the product 40 to be labeled to clear the bottle and drive the bottle into position within 1.0 second. At the same time, the feeder system completes the delivery of the label into position within this time period, and completes the coordinated peeling of the lower label plate 43a and the second peeling plate 38 and their respective resets within 0.5 seconds. One working cycle can be controlled within 1.6 seconds, and the labeling rate can reach 400 pieces / bottle per minute.
