Description

Technical Field

[0001] The present utility model relates to the technical field of marking devices, and more specifically, to a flying marking device for lid products. Background Art

[0002] A flying marking device is a device that marks or encodes an object during its movement. It is usually used in production lines or automated systems and can achieve precise marking under the condition that the object moves rapidly without manual intervention.

[0003] The flying marking device includes parts such as a lid separating device, a conveying device, and a marking device. For a conventional lid separating device, a closed structure is adopted, which is conducive to clamping by a double-axis / three-axis cylinder, and relaxation to achieve the separation of the lid. The gravity of the lid body is borne by the cylinder, and the service life of the cylinder is relatively short, and the maintenance cost is relatively high, and the clamping structure design is unreasonable. At the same time, due to the relatively fast conveying speed of flying marking, the stability requirements for the conveying device are relatively high. In the existing conveying device, due to the integrated setting of the conveying line belt and the unreasonable setting of the limiting structure, there is a certain amount of shaking and displacement during high-speed operation, and the stability is poor, and the problem of deviation in the marking position is likely to occur. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a flying marking device for lid products to solve the technical problems existing in the above background art.

[0023] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present utility model are given for the convenience of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and design various embodiments with various modifications suitable for specific purposes.

[0024] As Figures 1-4 shown, the technical solution of the present utility model provides a flying marking device for lid products, including a conveying device 4, a lid separating device 1, a marking and detecting device 2, and a rejection device 3 which are sequentially arranged above the conveying device 4 along the conveying direction. This device is used for marking lid products, such as milk powder lids, etc., and marking items such as production dates on their surfaces. The main steps are as follows: The products 5 are stacked on the lid separating device 1, and the lid separating device 1 separates the products one by one in sequence and drops them onto the conveying device 4. The products are marked and detected by passing through the marking and detecting device 2 during movement. The unqualified products are rejected by the rejection device 3, and the products with qualified marking are conveyed into the next process.

[0025] The lid separating device 1 includes symmetrically arranged driving cylinders 12, a slide block module 13 connected to the output ends of the driving cylinders 12, and a clamping part 14 located at the end of the slide block module 13. The driving cylinders 12 are arranged on the mounting support 11, and the slide block module 13 is slidably connected to the guide rails on the mounting support 11. An open protective cover 16 is arranged outside the driving cylinders 12, and a plurality of material storage rods 15 are arranged on the protective cover. The tops of the material storage rods 15 are bent outward, and the material storage rods 15 on the two groups of open protective covers 16 form a material storage hopper.

[0026] In the above solution, several material storage rods 15 form a material storage hopper structure. In the embodiment, four material storage rods 15 are given. The products are stacked and placed in the material storage hopper. The tops of the material storage rods 15 are bent outward to facilitate the placement of the products. The material storage hopper is open, facilitating the observation of the product state for timely adjustment and replenishment of the products. The placed products are stored in the material storage hopper. The products at the bottom are clamped by the clamping part 14, and the products are supported by the slider module 13. Compared with the traditional direct support by the cylinder, the support strength of the driving cylinder 12 is reduced, avoiding damage to the driving cylinder 12. In this solution, a single-axis cylinder is used.

[0027] The clamping part 14 includes an arc-shaped clamping block 141. An arc-shaped notch 142 is provided on the arc-shaped clamping block 141, and an inclined split cover slope 143 is provided below the arc-shaped notch 142. During blanking, the arc-shaped clamping blocks 141 on both sides open, and the products fall. When the lowermost product falls below the split cover slope 143, the two arc-shaped clamping blocks 141 clamp, separating the lowermost product from the adjacent product. The lowermost product falls onto the conveying device 4, and the above process is repeated, and the products fall onto the conveying device 4 in sequence. Then it reaches the marking and inspection device 2 for marking and inspection of whether the marking is qualified. The marking and inspection device 2 is implemented using existing technologies.

[0028] The rejection device 3 includes a rejection cylinder 31 and a rejection block 32 connected to the output end of the rejection cylinder 31. The rejection block 32 faces the conveying line, and the end face is a slope. When the product to be rejected reaches the rejection device 3, the rejection cylinder 31 drives the rejection block 32 to move forward to reject the product. The inclined rejection block 32 pushes the product obliquely forward, and the product rolls out of the conveying device 4.

[0029] The conveying device 4 includes a driving motor 41, a roller shaft module 42, a belt module, and a support component located below the belt module. The support component contacts the lower surface of the belt module, and the contact surface between the support component and the belt module is a smooth surface. The driving motor 41 drives the roller shaft module 42 to rotate to drive the belt module. The support component is used to support and limit the belt module, making the operation of the belt module more stable and ensuring the accurate marking position of the product.

[0030] Above the belt module and on both sides of the belt module, there are limit baffles 47 provided. The limit baffles 47 are used to limit the product, ensuring that the product is conveyed forward along a specific trajectory to the marking position for marking. The belt module includes two conveying belts 43 arranged at intervals, and a limit strip 431 is provided in the middle of the belt. A circular bayonet 421 is provided on the roller shaft module 42 corresponding to the limit strip 431. The support assembly includes a first support plate 44 and a second support plate 45, and a limit groove 46 adapted to the limit strip 431 is formed between the first support plate 44 and the second support plate 45. The ends of the first support plate 44 and the second support plate 45 are bent downward.

[0031] In the above solution, the limit strip 431 on the conveying belt 43 is stuck in the circular bayonet 421 and the limit groove 46. During the movement process, the left-right displacement is avoided. At the same time, it is supported by the first support plate 44 and the second support plate 45. The surfaces of the first support plate 44 and the second support plate 45 are smooth, reducing the friction with the conveying belt 43. The two conveying belts 43 are arranged at intervals to avoid the detection photoelectric eye from being accidentally touched.

[0032] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
