Description

Technical Field

[0001] The utility model relates to the technical field of toy processing, in particular to a toy detection device. Background Art

[0002] Assembly toys, especially capsule toys, generally require weighing and metal testing during the production process because they have relatively more internal parts and a relatively small structure. This is conducive to quality control and safety.

[0003] In response to such situations, current inspection lines are generally designed with weighing and metal detection equipment to detect products conveyed by conveyor belts, such as CN208213694U - a metal detection and weighing transmission mechanism. This patent has a novel design and a simple structure, and realizes the mechanical automation of the front end of product packaging, so that metal detection and weighing can be performed on the same section of the production line, and unqualified products are automatically rejected, avoiding the need to perform metal detection after packaging is completed, thereby improving production efficiency. However, the automatic rejection device used in this patent does not disclose the specific structure, and the products detected and weighed in this application are similar to egg products, with a relatively small overall size and a relatively smooth ellipsoidal appearance. If the traditional blowing or pushing method is used to reject the product, it is easy for the product to be subjected to force and rotate sideways, making it difficult to accurately remove unqualified products from the conveyor belt. Utility Model Content

[0004] In order to overcome one of the deficiencies of the prior art, an object of the present invention is to provide a toy inspection device that can effectively and accurately reject unqualified products.

[0005] In order to solve the above problems, the technical solutions adopted by the present invention are as follows:

[0007] Furthermore, a buffer pad is provided on the intercepting plate on the feeding side.

[0008] Furthermore, a rotating shaft is provided on the intercepting plate, and the rotating shaft is rotatably mounted on the telescopic end of the waste rejection electric cylinder. One end of the intercepting plate close to the waste rejection electric cylinder is connected to one end of a tension spring, and the other end of the tension spring is connected to the telescopic end of the waste rejection electric cylinder.

[0009] Furthermore, mounting plates are provided on both sides of the feed end of the discharge hopper, and the mounting plates are mounted on the mounting base by screws.

[0010] Furthermore, a gate is provided at the bottom of the discharge hopper.

[0011] Furthermore, a conveying pipe is connected to the output end of the feeding mechanism, the conveying pipe is connected to the input end of the conveyor belt, and an intercepting mechanism is provided on the discharge end of the conveying pipe.

[0013] Furthermore, the feeding mechanism is a vibration feeding mechanism.

[0014] Furthermore, the weighing mechanism is a belt scale.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model discloses a toy detection device which designs a new reject mechanism on an existing detection line. The reject mechanism uses an intercepting plate to intercept the toys conveyed on the conveyor belt. Due to the spherical appearance of the toys, the intercepting plate can be used in conjunction with the conveyor belt to directly intercept the products and convey them into the discharge hopper. For toys which are difficult to enter the discharge hopper on their own, the high-pressure airflow blown out by the blowing pipe is used to blow the products into the discharge hopper, or the conveyor belt is used to roll the products into the discharge hopper on its own. The whole reject mechanism has a simple structure, can effectively target the reject work of spherical products, and has a high reject accuracy rate.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Reference Figures 1 to 3 The toy detection device shown in the figure includes a frame 10, a weighing mechanism 20, a metal detection mechanism 30 and a conveyor belt 40 arranged on the frame 10, a feeding mechanism 50 is provided on the frame 10, and the feeding mechanism 50 is connected to one end of the conveyor belt 40 for feeding. The weighing mechanism 20 and the metal detection mechanism 30 are both provided on the conveyor belt 40, and a waste rejection mechanism 60 is provided on the end of the conveyor belt 40 where the weighing mechanism 20 and the metal detection mechanism 30 are discharged. The waste rejection mechanism 60 includes a mounting base 61, a discharge hopper 62 and a rejecting mechanism. The waste electric cylinder 63, the mounting base 61 is mounted on the frame 10 at the bottom of the conveyor belt 40, the discharge hopper 62 and the waste rejection electric cylinder 63 are respectively arranged on both sides of the mounting base 61, and an intercepting plate 64 is installed on the telescopic end of the waste rejection electric cylinder 63. The intercepting plate 64 is located on the feeding side of the conveyor belt 40 and is provided with an air blowing pipe 65. The waste rejection electric cylinder 63 can drive the intercepting plate 64 to cross the conveyor belt 40, and the air blowing pipe 65 can blow the unqualified products transported on the conveyor belt 40 into the discharge hopper 62.

[0025] The weighing mechanism 20 and metal detection mechanism 30 are both common mechanisms and will not be described in detail in this application. For example, the weighing mechanism 20 is a common belt-type weighing mechanism, such as a belt scale. In this application, since the product is spherical, the feeding mechanism 50 may be a vibrating feeding mechanism. However, since the product is a capsule toy, a baffle-type conveyor belt can be used in the actual feeding process, with only one product being stored between two adjacent baffles. It should be noted that baffles are provided on both sides of the conveyor belt 40 in this application to prevent the product from rolling away.

[0026] The toy detection device is designed with a new rejection mechanism 60 on the existing detection line. The rejection mechanism 60 uses an interception plate 64 to intercept the toys conveyed on the conveyor belt 40. Due to the spherical appearance of the toys, the interception plate 64 can be used in conjunction with the conveyor belt 40 to directly intercept the products and send them into the discharge hopper 62; for toys that are difficult to enter the discharge hopper 62 on their own, the high-pressure airflow blown out by the blow pipe 65 is used to blow the products into the discharge hopper 62, or the products are rolled into the discharge hopper 62 on their own together with the conveyor belt 40. The entire rejection mechanism 60 has a simple structure and can effectively target the rejection of spherical products with a high rejection accuracy.

[0027] In one embodiment of the present application, in order to better protect the product, the intercepting plate 64 is provided with a buffer pad 66 on one side of the feed. Wherein, the buffer pad 66 has some wedge-shaped surfaces that are conducive to cooperating with the conveyor belt 40 to automatically roll the product into the discharge hopper 62.

[0028] See also Figure 1 and Figure 2 To prevent products carried by the conveyor belt 40 from rebounding after impacting the interception plate 64, in one embodiment of the present application, a rotating shaft 67 is provided on the interception plate 64. The rotating shaft 67 is rotatably mounted on the telescopic end of the reject cylinder 63. One end of a tension spring 68 is connected to the end of the interception plate 64 near the reject cylinder 63, and the other end of the tension spring 68 is connected to the telescopic end of the reject cylinder 63. This design provides the interception plate 64 with a certain buffering capacity, reducing impact.

[0029] See also Figures 1 to 2 In one embodiment of the present application, for ease of assembly and disassembly, mounting plates are provided on both sides of the feed end of the discharge hopper 62, which are mounted on the mounting base 61 via screws. It should be noted that in the present application, the discharge hopper 62 is generally arc-shaped, with its inlet facing the side of the conveyor belt 40. This design allows the product intercepted by the interception plate 64 to be directly received, effectively catching the product that has bounced. In actual use, a collection box is generally provided at the bottom of the discharge hopper 62 to facilitate the collection and transfer of defective products.

[0030] In the improved scheme of the above embodiment, in order to facilitate the replacement of the aggregate box without stopping the operation of the conveyor belt 40, in one embodiment of the present application, a gate 69 is provided at the bottom of the discharge hopper 62. Such a design can block the bottom of the discharge hopper 62, so that the discharge hopper 62 can temporarily take over unqualified products, providing time for the staff to replace the aggregate box.

[0031] See also Figure 1 and Figure 3 In one embodiment of the present application, to allow products to be fed one by one onto the conveyor belt 40 for subsequent weighing and testing, a conveying pipe 51 is connected to the output end of the loading mechanism 50. The conveying pipe 51 communicates with the input end of the conveyor belt 40. An interception mechanism 70 is provided at the discharge end of the conveying pipe 51. The interception mechanism 70 can be a conventional telescopic structure or a conveying structure employing a wheel groove structure, and its design is determined based on the specific situation. Furthermore, the conveying pipe 51 can be a conveying channel, which can prevent products from rolling out of it during natural rolling.

[0032] In one embodiment of the present application, the interception mechanism 70 includes an interception electric cylinder 71 and an interception tongue 72 disposed at the output end of the interception electric cylinder 71. The interception electric cylinder 71 is mounted on the outside of the conveying pipe 51. The interception electric cylinder 71 drives the interception tongue 72 to extend into the conveying pipe 51 to intercept the products being conveyed therein. In this application, a position sensor is installed within the conveying pipe 51 to lower products one by one based on their rolling distance. This technology is prior art and will not be described in detail herein.

[0033] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
