Abstract
Description
Technical Field
[0001] This application relates to the field of detection technology, and more specifically to a rejection device with an auxiliary guiding mechanism. Background Technology
[0002] In the food and beverage industries, high-speed packing of smaller cartons and bottles on production lines is crucial. Defective products are removed by rejection equipment. Traditional rejection equipment either kicks defective products onto the next or third conveyor belt or chain plate during rejection. Furthermore, the rejection rods in these devices are relatively long, requiring matching guiding mechanisms, which makes the entire structure cumbersome and generates abnormal noise during operation, failing to meet the requirements of high-speed rejection and resulting in high maintenance costs. Alternatively, some current rejection equipment uses long-rod rejection heads for direct rejection (without additional guidance). This structure is simple and can meet high-speed rejection requirements, but the impact force generated by the swinging motion causes the pusher to wear out, deform, or break quickly, leading to cumbersome and costly maintenance. Additionally, the swinging motion of the pusher during extension and retraction causes the rejection points of cartons and bottles to vary, resulting in different material movement trajectories and further increasing the number of defective products, wasting materials and reducing production efficiency. Summary of the Invention
[0003] To overcome the above-mentioned shortcomings, the purpose of this application is to propose a rejection device with an auxiliary guiding mechanism, which increases the strength of the push rod and reduces maintenance costs.
[0004] To achieve the above objectives, this application adopts the following technical solution:

[0008] The push block has at least one groove on its first side and at least one protrusion on its second side opposite to the first side, which extends in the same direction as the groove. Two adjacent push blocks are configured such that the protrusion on the second side of one push block matches the groove on the first side of the other push block.
[0009] The rejection component is located on the side of the substrate away from the pusher block, and the rejection component is matched with the pusher block one by one.

[0028] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.
[0029] As mentioned in the background section, rejection equipment is installed on production lines in industries such as food and beverage to remove defects detected during high-speed packing. Currently, the rejection rods in these equipment are quite long, causing abnormal noise and wobbling during operation, and the maintenance costs are high.
[0030] Based on the applicant's structural improvements to existing rejection equipment, a rejection device with an auxiliary guiding mechanism is proposed, comprising: a base plate having multiple through holes; a first side plate and a second side plate disposed opposite to each other on one side of the base plate, wherein multiple push blocks (preferably an even number of push blocks) are stacked between the first side plate and the second side plate, and the number of push blocks is the same as the number of through holes; the first side of the push block has at least one groove, and the second side of the push block opposite to the first side has at least one protrusion extending in the same direction as the groove; adjacent push blocks are configured such that the protrusion of the second side of one push block matches the groove of the first side of the other push block; and rejection components are located on the side of the base plate away from the push blocks, and the rejection components are connected to each push block one by one. The sidewalls of the first side plate and the second side plate are respectively provided with protrusions, which are used to match the grooves on the first side of the push blocks. Through this design, a guiding structure is provided on the push blocks, and adjacent push blocks guide each other, enhancing the strength of the rejection rod while solving the problem of easy swinging of the rejection rod during long operation. Preferably, the first side of the pusher has two spaced-apart and parallel grooves, and the second side of the pusher opposite to the first side has two protrusions with the same groove extension direction. Preferably, the number of pushers is between 8 and 20.
[0031] Next, combine Figures 1 to 7 This application describes in detail the rejection device with an auxiliary guiding mechanism according to the embodiments of the present application.
[0032] The rejection device 100 includes a substrate 110, on which a plurality of through holes are provided;
[0033] One side of the substrate 110 includes a first side plate 120a and a second side plate 120b disposed opposite to each other. A push block is stacked between the first side plate 120a and the second side plate 120b. Each push block is matched with a cylinder, and each cylinder is matched with a rejection push rod. One side of the rejection push rod passes through a through hole and connects to the push block. In this embodiment, 12 stacked push blocks 131-1312 are included. Each push block is matched with a rejection component, which is located on the side of the substrate 110 away from the push block. The rejection component includes a cylinder and a rejection push rod. The cylinder is connected to an air source via a pipeline, and the rejection push rod is moved (extended / retracted) based on the control action of an industrial control computer. The industrial control computer controlling the cylinder's movement is prior art and will not be described in detail here.
[0034] The connection between the pusher block 132 and the matching rejection component is described as an example. The rejection component includes a cylinder 132b and a rejection push rod 132a. The rejection push rod 132a is connected to the pusher block 132 through a through hole. The cylinder 132b is fixed on the base plate 110. The rejection push rod 132a is extended / retracted based on the action of the cylinder 132b pushing the rejection push rod 132a.
[0035] The first side plate 120a and the second side plate 120b are respectively fixed to one side of the base plate 110 by fasteners. The base plate 110 has through holes 110a that match the number of rejection pushers.
[0036] The second side plate 120b has a protrusion 120b1 on its side wall, which extends along the height direction of the second side plate 120b. Preferably, there are two protrusions 120b1, which are arranged parallel to each other. The protrusions 120b1 match the grooves on the first side of the push block. The second side of the push block opposite to the first side has a protrusion that extends along the height direction of the push block and matches the grooves on the first side of the adjacent push block. In this way, when multiple push blocks are stacked in sequence, they are guided by the matching of the protrusions and grooves, which can increase the mechanical strength of the push block and thus increase the mechanical strength of the push rod connected to the push block, and reduce the amplitude of swinging / shaking during operation. Taking push block 134 as an example, the first side of the push block 134 has a groove 134a that matches the first side, and the second side of the push block opposite to the first side has a protrusion 134b that extends along the height direction of the push block. Preferably, the groove 134a and the protrusion 134b are arranged opposite to each other. This method does not increase the weight or size of the rejection equipment. Preferably, the cross-sections of the groove 134a and the protrusion 134b can be rectangular.
[0037] Preferably, the structure of the second side panel is the same as that of the first side panel, and preferably, the second side panel and the first side panel are designed symmetrically.
[0038] In one embodiment, the groove has a trapezoidal or dovetail-shaped cross section, and the protrusion and projection are also trapezoidal or dovetail-shaped, so that when adjacent push blocks are stacked, they can only slide in opposite directions and cannot be separated.
[0039] This rejection equipment is installed on the production line. Taking a rejection equipment with 12 push blocks (push blocks 131-1312) as an example, rejection push rods 131a-1312a are arranged sequentially. When material passes through the rejection area, the industrial control computer controls the rejection push rods 131a, 132a, 133a, 134a, 135a, 136a, 137a, 138a, 139a, 1310a, 1311a, and 1312a to push out rapidly in sequence. The push rods form a guide rail to push the material out. The purpose of having multiple push rods is that when two adjacent materials need to be pushed out and the other needs to continue running normally, the industrial control computer controls the push rods to retract.
[0040] When two adjacent materials are about to be ejected and the other is about to run normally, the following actions are controlled by the industrial control computer: ejection pushers 131a, 132a, 133a, and 134a are ejected sequentially; ejection pusher 135a is ejected while pusher 131a retracts; ejection pusher 135a is ejected while pusher 132a retracts; ejection pusher 137a is ejected while pusher 133a retracts; and ejection pusher 138a is ejected. When the push rod 134a retracts, the push rod 139a extends and the push rod 135a retracts; when the push rod 1310a extends and the push rod 136a retracts; when the push rod 1311a extends and the push rod 137a retracts; when the push rod 1312a extends and the push rod 138a retracts, the push rods 139a, 1310a, 1311a, and 1312a retract sequentially. By providing guiding grooves and protrusions on the push blocks corresponding to the push rods, adjacent push blocks guide each other, increasing strength and reducing push rod wobbling.
[0041] The above embodiments are only for illustrating the technical concept and features of this application, and are intended to enable those skilled in the art to understand the content of this application and implement it accordingly. They should not be used to limit the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit and essence of this application should be included within the scope of protection of this application.
