Description

Technical Field

[0001] This utility model relates to the field of product packaging inspection technology, specifically to an empty package inspection and rejection device. Background Technology

[0002] In the process of cosmetic packaging, in order not to affect subsequent packaging and sales, it is necessary to select empty cosmetic packages.

[0003] Chinese patent CN209739522U discloses an empty package rejection device, including a pair of sensing devices, a rejection device, a rejection port, a conveyor belt, a control device, and a frame. The sensing devices and the rejection device are both connected to the control device. The conveyor belt is mounted on the frame. The rejection device includes a nozzle, a solenoid valve, and an air compressor. The nozzle is located on one side of the frame and opposite the rejection port. The air compressor and the solenoid valve are connected to the nozzle, and the solenoid valve is connected to the control device. The sensing devices are symmetrically arranged at the middle edge of the frame. However, this device still has the following problems during use:

[0004] The nozzle is a single fixed setting. When the product moves to the nozzle position after weight detection, the nozzle can blow out the empty packaged product to achieve material separation. However, overweight packaging is still easy to occur during the production process. At this time, the nozzle cannot remove the overweight packaged product, so the overweight product and qualified product are moved out through the same conveyor device. This makes it inconvenient to remove the overweight packaged product when the product is packaged in the subsequent process.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0035] In some embodiments, please refer to the accompanying drawings. Figures 1-4 An empty package inspection and rejection device includes a base plate 1, a double-sided flipping appearance inspection mechanism 2, a weighing belt conveyor 3, a material distribution belt conveyor 4, a discharge belt conveyor 5, and a material distribution mechanism 6; the upper end of the base plate 1 is equipped with a double-sided flipping appearance inspection mechanism 2 for inspecting the appearance of the front and back of the product.

[0036] like Figure 1 As shown, the double-sided flipping appearance inspection mechanism 2 includes a first appearance rejection component, a second appearance rejection component, a flipping component, and a camera 25; both the first appearance rejection component and the second appearance rejection component are installed on the upper left side of the base plate 1; and the installation position of the second appearance rejection component is located to the right of the first appearance rejection component.

[0037] Both the first appearance rejection assembly and the second appearance rejection assembly are composed of a lifting transplanter 21; the lifting transplanter 21 is fixedly installed on the upper end of the base plate 1;

[0038] The lifting transplanter 21 adopts mature technologies in the industry, such as the lifting transplanter in patent number CN220945704U;

[0039] Furthermore, the lifting transplanter 21 consists of a conveying section, a lifting section, and a transplanting section;

[0040] A flipping assembly is installed between the first appearance rejection assembly and the second appearance rejection assembly of the lifting transplanter 21; the flipping assembly is installed on the upper left side of the base plate 1; a camera 25 is fixedly installed on the upper side of the outer shell of the lifting transplanter 21.

[0041] Both the first and second appearance rejection components have a waste bin installed in front of the lifting transplanter 21; and the waste bin is placed on the upper part of the base plate 1.

[0042] The weighing belt conveyor 3 is fixedly installed at the upper middle part of the base plate 1;

[0043] The weighing belt conveyor 3 adopts mature technologies in the industry; for example, the high-precision automatic weighing belt conveyor produced by Shanghai Dingtuo Industrial Co., Ltd.

[0044] A material separating mechanism 6 for separating products of different weights is installed on the upper right side of the base plate 1.

[0045] The material distribution mechanism 6 includes a rotation drive assembly, a blowing assembly, an empty packaging collection box 66, and an overweight packaging collection box 67; the rotation drive assembly is installed in the middle of the upper end of the base plate 1; a material distribution belt conveyor 4 is installed on the rotation drive assembly; the blowing assembly is installed at the rear right side of the upper end of the base plate 1; the empty packaging collection box 66 is placed at the front right side of the upper end of the base plate 1; the overweight packaging collection box 67 is placed at the right side of the upper end of the base plate 1.

[0046] The discharge belt conveyor 5 is fixedly installed on the upper right side of the base plate 1;

[0047] In this invention, after production, the bagged products are moved to the conveying section of the first appearance rejection component lifting and transplanting machine 21 via a conveying device. Then, the camera 25 of the first appearance rejection component performs an appearance inspection on the front of the product. If the inspection fails, the lifting section of the lifting and transplanting machine 21 moves the transplanting section upward, so that the transplanting section contacts the product. Then, the transplanting section moves the defective product forward. If the inspection passes, the conveying section of the lifting and transplanting machine 21 moves the product that passes the front appearance inspection to the right onto the flipping component.

[0048] Subsequently, the flipping component rotates the product 180 degrees, causing the product to move upwards and onto the conveyor section of the second appearance rejection component lifting and transplanting machine 21. Then, the camera 25 of the second appearance rejection component performs an appearance inspection on the reverse side of the product. If the inspection fails, the lifting part of the lifting and transplanting machine 21 moves the transplanting part upwards, bringing it into contact with the product. The transplanting part then moves the defective product forward. If the inspection passes, the conveyor section of the lifting and transplanting machine 21 moves the product that has passed the appearance inspection on both sides to the right onto the weighing belt conveyor 3.

[0049] Then, the weighing belt conveyor 3 weighs the product. After the weighing is completed, the weighing belt conveyor 3 drives the product to continue moving to the material distribution belt conveyor 4.

[0050] If the weight of the product is lower than the set value, the product can be judged as an empty package and a defective product; at this time, the blowing component will blow the product into the empty package collection box 66 to complete the collection of the empty package product;

[0051] If the weight of the product is higher than the set value, it can be determined that the product has been packaged repeatedly, which means it is an overweight and unqualified product. At this time, the rotating drive component works to drive the material distribution belt conveyor 4 to rotate downward, so that the discharge end of the material distribution belt conveyor 4 tilts downward and toward the overweight packaging collection box 67. Then the material distribution belt conveyor 4 works to move the overweight product into the overweight packaging collection box 67.

[0052] If the product passes the appearance inspection on both sides and the weighing inspection, the material distribution belt conveyor 4 will then move the product to the right onto the discharge belt conveyor 5; subsequently, the discharge belt conveyor 5 will move the qualified product to the right.

[0053] By repeating the above operations, continuous inspection of the product's appearance and weight can be achieved.

[0054] By combining the flipping component and the lifting and transplanting machine 21, the device can perform continuous appearance inspection on both sides of the product, ensuring the quality of product inspection and avoiding the extra workload of manual material separation. It also provides the necessary prerequisite for subsequent weight inspection, preventing the problem of products meeting weight requirements but having damaged appearances, which would affect subsequent product packaging operations. By combining the rotation drive component and the blowing component, the device can simultaneously perform the removal of empty packages and the removal of overweight products, preventing overweight products from affecting subsequent product packaging operations and further improving the practicality of the device.

[0055] like Figure 3 As shown, the flipping assembly includes a rotating disk 22, limiting components, a servo motor 24, and a fixing frame 26; the fixing frame 26 is fixedly installed on the upper left side of the base plate 1; the front and rear ends of the rotating disk 22 are rotatably installed on the inner walls of the front and rear sides of the fixing frame 26; the servo motor 24 is fixedly installed on the front end of the rotating disk 22; and the output end of the servo motor 24 is fixedly connected to the rotating disk 22; multiple sets of limiting components are installed on the outer end of the rotating disk 22; and the limiting components are evenly distributed in a circular array on the rotating disk 22.

[0056] The limiting component consists of two clamping plates 23, both of which are fixedly installed on the outer end of the rotating disk 22; the distance between the two clamping plates 23 is greater than the thickness of the product; and the width of the clamping plates 23 is less than the width of the product.

[0057] like Figure 4 As shown, the rotation drive assembly includes a mounting frame 61, a fixed bait plate 62, a cylinder 68, a base 69, a connecting push frame 610, and a limiting frame 611; the mounting frame 61 is fixedly installed in the middle of the upper end of the base plate 1; the fixed bait plates 62 are symmetrically fixedly installed on the front and rear sides of the upper end of the mounting frame 61; the outer shells of the front and rear ends of the material distribution belt conveyor 4 are hinged to the front and rear fixed bait plates 62; the limiting frame 611, which is used to support and limit the material distribution belt conveyor 4, is fixedly installed in the upper end of the base plate 1;

[0058] The base 69 is fixedly installed on the upper end of the base plate 1; the connecting push frame 610 is fixedly installed on the right side of the outer shell of the material distribution belt conveyor 4; the lower end of the cylinder 68 is hinged to the base 69; and the output end of the cylinder 68 is hinged to the connecting push frame 610.

[0059] like Figure 4 As shown, the blowing assembly includes a stand 63, a blowing gun 64, and an air pipe 65; the stand 63 is fixedly installed on the upper rear side of the base plate 1; the blowing gun 64 is fixedly installed on the front end of the stand 63; the air pipe 65 is fixedly installed on the rear end of the blowing gun 64; and the outside of the blowing gun 64 is connected to an air pump; the installation height of the air pipe 65 is flush with the upper end of the material distribution belt conveyor 4.

[0060] In this invention, after production, the bagged product, face up, is moved by a conveying device to the conveying section of the first appearance rejection component lifting and transplanting machine 21. Then, the camera 25 of the first appearance rejection component performs an appearance inspection on the front of the product. If the inspection fails, the lifting section of the lifting and transplanting machine 21 moves the transplanting section upward, so that the transplanting section contacts the product. Then, the transplanting section moves the defective product forward. If the inspection passes, the conveying section of the lifting and transplanting machine 21 moves the product that has passed the front appearance inspection to the right between the two clamping plates 23 of a set of limiting components. Since the width of the clamping plate 23 is less than the width of the product, the left side of the front of the product will be exposed at this time.

[0061] Subsequently, the servo motor 24 drives the rotating disk 22 to rotate 180 degrees to the right. The clamping plate 23 rotates along with the rotating disk 22, and also drives the product to rotate to the right, so that the reverse side of the product faces upward. As the clamping plate 23 continues to rotate, the product slides out from between the two clamping plates 23 onto the conveyor section of the second appearance rejection component lifting and transplanting machine 21. Then, the camera 25 of the second appearance rejection component operates to perform appearance inspection on the reverse side of the product. If the inspection fails, the lifting part of the lifting and transplanting machine 21 operates to drive the transplanting part upward, so that the transplanting part contacts the product. Then, the transplanting part operates to move the defective product forward. If the inspection passes, the conveyor section of the lifting and transplanting machine 21 operates to move the product with qualified appearance inspection on both sides to the right onto the weighing belt conveyor 3.

[0062] Then, the weighing belt conveyor 3 weighs the product. After the weighing is completed, the weighing belt conveyor 3 drives the product to continue moving to the material distribution belt conveyor 4.

[0063] If the product weighs less than the set value, it can be determined that the product is an empty package and is unqualified; at this time, the blowing gun 64 works to blow the product into the empty package collection box 66, thus completing the collection of the empty package product.

[0064] If the product weighs more than the set value, it can be determined that the product has been packaged repeatedly, which means it is an overweight and unqualified product. At this time, the cylinder 68 works to pull the connecting pusher 610 downward, causing the material distribution belt conveyor 4 to rotate downward around the hinge point with the fixed feed plate 62, so that the discharge end of the material distribution belt conveyor 4 tilts downward and toward the overweight packaging collection box 67; then the material distribution belt conveyor 4 works to move the overweight product into the overweight packaging collection box 67.

[0065] If the product passes the appearance inspection on both sides and the weighing inspection, the material distribution belt conveyor 4 will then move the product to the right onto the discharge belt conveyor 5; subsequently, the discharge belt conveyor 5 will move the qualified product to the right.

[0066] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
