Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and further to a blister pack product conveying device. Background Technology

[0002] Small-package blister packs, with their excellent protective performance, ease of use, good safety, and efficient production characteristics, have successfully combined multiple advantages and are widely used in industries such as pharmaceuticals, health products, electronic components, and small food products.

[0003] In automated coding production lines for blister products, products are fed into a conveyor belt after being fed by a vibratory feeder. However, during the feeding and transport process, products may still stack or have insufficient spacing. If such products are directly transported to the coding station, it can easily lead to interference with the vision system and deviations in coding position, resulting in a large number of defective products. Traditional single-belt conveyor methods are difficult to effectively address this problem. In addition, long-distance single-belt conveyors are prone to vibration and speed fluctuations during operation, which can further affect the accuracy of coding timing, reducing production efficiency and product quality.

[0004] Therefore, it is necessary to design a blister pack product conveying device to solve the above problems. Utility Model Content

By setting up a dual conveying mechanism with height and speed differences and an intermediate roller assembly, it effectively solves the problems of coding and identification interference and positional deviation caused by product stacking, uneven spacing, and belt vibration in traditional single belt conveyor.

Detailed Implementation

[0031] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0032] To keep the drawings concise, each figure only schematically shows the parts relevant to the utility model, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0033] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0034] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] In one embodiment, refer to the appendix to the specification. Figure 1 The present invention provides a blister pack product conveying device, comprising: a first conveying mechanism 1, a second conveying mechanism 2, and a roller assembly 3; the first conveying mechanism 1 and the second conveying mechanism 2 are arranged sequentially along the product conveying direction, and the roller assembly 3 is located between the first conveying mechanism 1 and the second conveying mechanism 2; the highest point of the roller assembly 3 is higher than the top surface of the first conveying mechanism 1 and the top surface of the second conveying mechanism 2 to form a height difference; the height of the second conveying mechanism 2 is not higher than the height of the first conveying mechanism 1, and the linear velocity of the second conveying mechanism 2 is greater than the linear velocity of the first conveying mechanism 1.

[0037] In this embodiment, by setting up a first conveying mechanism 1, a second conveying mechanism 2, and an intermediate roller assembly 3 with height and speed differences, the problems of coding recognition interference and position deviation caused by product stacking, uneven spacing, and belt vibration in traditional single belt conveyor are effectively solved. The device can automatically separate stacked materials, stabilize spacing, and suppress speed fluctuations during the conveying process, thereby significantly improving coding accuracy and production reliability. It is suitable for automated production lines of various blister products.

[0038] In one embodiment, refer to the appendix to the specification. Figure 1 The roller assembly 3 includes at least one roller 31 driven by a micro servo motor 32, and the height of the roller 31 is adjustable. The micro servo motor 32 can precisely adjust the rotation speed and direction of the roller 31, thereby actively guiding and separating products; the height-adjustable roller 31 allows the device to flexibly adapt to different specifications of blister products and process requirements; this structure not only enhances the effect of product separation and spacing control, but also significantly improves the adaptability and flexibility of the entire conveying system to different production needs, further ensuring the stability and production efficiency of the coding station.

[0039] Furthermore, the height difference between the highest point of the roller assembly 3 and the top surface of the first conveying mechanism 1 is 2-4 mm, such as 3 mm; and / or, the height difference between the highest point of the roller assembly 3 and the top surface of the second conveying mechanism 2 is 2-4 mm, such as 3 mm. By setting the highest point of the roller assembly 3 to be 2-4 mm higher than the top surfaces of the first conveying mechanism 1 and the second conveying mechanism 2 respectively, a slight drop and posture reset can occur when the product is transferred from the first conveying mechanism 1 to the second conveying mechanism 2 via the roller assembly 3, thereby effectively separating potentially stacked blister products.

[0040] Furthermore, the linear speed of the second conveyor 2 is 15%-25% higher than that of the first conveyor 1, such as 18%, 20%, or 22%. This allows the products to separate quickly and stably after passing through and being accelerated by the roller assembly 3, forming a uniform and appropriate gap. This not only effectively eliminates the problems of product stacking or excessively small spacing, but also provides a clear and orderly working environment for visual recognition and printing operations at the subsequent coding station, thereby significantly improving the accuracy of coding positions and the overall stability of the production line.

[0041] In one embodiment, refer to the appendix to the specification. Figure 1 The first conveying mechanism 1 includes a first driving roller 11, a first driven roller, and a first annular conveyor belt 12 tensioned between the two. The first driving roller 11 is connected to and independently driven by a first drive motor. The second conveying mechanism 2 includes a second driving roller 21, a second driven roller 22, and a second annular conveyor belt 23 tensioned between the two. The second driving roller 21 is connected to and independently driven by a second drive motor, and the rotational speed of the second drive motor is higher than that of the first drive motor.

[0042] In this embodiment, the first conveying mechanism 1 and the second conveying mechanism 2 adopt independent conveying structures, which enables the second conveying mechanism 2 to maintain a stable speed higher than that of the first conveying mechanism 1, thereby forming a reliable speed difference with the front section. This structure ensures that the product can be accelerated quickly and smoothly after passing through the roller assembly 3, effectively increasing the product spacing, eliminating stacking, and providing a stable and orderly conveying environment for the subsequent coding station.

[0043] Furthermore, the first conveying mechanism 1 and the second conveying mechanism 2 have the same structure; or, the first conveying mechanism 1 and the second conveying mechanism 2 have different structures. Depending on space constraints, cost requirements, or specific product needs in actual production, the same structure can be flexibly selected to simplify maintenance and spare parts management, or different structures can be used to optimize the conveying performance of specific sections; while ensuring effective product separation, stable spacing, and improved coding accuracy, the application range and economy of the entire conveying device are significantly enhanced.

[0044] It should be noted that the specific structures of the first conveying mechanism 1 and the second conveying mechanism 2 are described with reference to the accompanying drawings. In actual use, other structures may also be used, as long as the above functions can be achieved. This is only for better illustrating the present invention and should not constitute a limitation on the present invention.

[0045] In one embodiment, refer to the appendix to the specification. Figure 1 , Figure 2 The second annular conveyor belt 23 is light-colored or white. The conveying device also includes a feeding device 6 located at the front of the first conveying mechanism 1, a coding system 7 located at the rear of the second conveying mechanism 2, and an illumination source 4 located above or to the side of the second conveying mechanism 2. The illumination source 4 is used to enhance the contrast between the product and the background, making the product outline clearer in the visual system. This solution provides a highly clear imaging environment with extremely low interference for the visual recognition system, ensuring that the camera can accurately capture the outline and position of each product. Combined with speed control and spacing adjustment functions, the recognition accuracy of the coding position is further improved, avoiding coding errors caused by image blurring or insufficient contrast, and significantly improving production quality and the reliability of automated operation.

[0046] Furthermore, a speed synchronizer is installed on the second conveying mechanism 2 to detect the linear speed of the second annular conveyor belt 23 in real time and transmit the speed signal to the coding system 7, so that the coding sequence is dynamically synchronized with the conveying speed. This effectively eliminates the coding position deviation problem caused by conveyor belt speed fluctuations, long-term wear, or load changes, ensuring that each blister product is accurately coded at the set position.

[0047] Furthermore, the conveying device also includes a frame 5, on which the first conveying mechanism 1 and the second conveying mechanism 2 are mounted, and the heights of the first conveying mechanism 1 and / or the second conveying mechanism 2 are adjustable. The frame 5 provides a stable mounting foundation for each conveying mechanism, effectively suppressing vibration and shaking during operation and ensuring conveying stability; the adjustable heights of the first conveying mechanism 1 and / or the second conveying mechanism 2 allow for flexible adjustment of the working position of the conveying section according to product specifications and production needs, optimizing product transition and separation effects.

[0048] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0049] It should be noted that the above embodiments can be freely combined as needed. The above are only optional embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
