Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet and thin material production technology, specifically a material distribution and conveying mechanism with multiple rejection mechanisms. Background Technology
[0002] With the development of automation technology and intelligent manufacturing, many modern production lines have achieved a high degree of automation. In the processing of sheet materials such as flat printed materials, packaging bags and paper, conveyor lines are usually used to complete multiple processes.
[0003] In production practice, to reduce labor costs, intelligent identification systems are often used to detect defects in materials on the production line, and defective materials are then removed by a rejection mechanism. In existing technology, when materials are transported in multiple paths, the rejection mechanism removes both defective and good materials in parallel paths, facilitating subsequent bundling and packaging of a set quantity of materials. However, manually sorting and recycling mixed good and defective materials increases labor costs, while discarding them results in waste and hinders cost reduction. Utility Model Content
[0004] This utility model discloses a material distribution and conveying mechanism with multiple rejection mechanisms. It solves the technical problem of waste caused by material rejection in existing technologies, and has the technical effects of reasonable structure, reduced waste, and lower production costs. The technical solution adopted is as follows:
[0005] A material distribution and conveying mechanism with multiple rejection mechanisms includes multiple rejection mechanisms and a distribution assembly disposed above a conveying component. The conveying component conveys material forward, and the distribution assembly forms multiple distribution channels to distribute the material in different directions. The multiple rejection mechanisms are disposed near the rejection channels formed by the conveying component. The multiple rejection mechanisms include multiple independently operating rejection units, each corresponding to a different distribution channel to drive the material on the corresponding channel to fall from the rejection channel. Preferably, the multiple rejection mechanisms are disposed above the rejection channels formed by the conveying component.
[0006] Based on the above technical solution, there are multiple rejection channels arranged sequentially along the conveying direction of the conveying component, and there are multiple rejection mechanisms arranged in a one-to-one correspondence with the rejection channels.
[0007] Based on the above technical solution, the rejection unit includes a pressing part and / or a guiding part. The rejection unit is vertically displaceable above the rejection channel. When the rejection unit moves downward and approaches the rejection channel, the pressing part presses down against the material to allow the material to enter the rejection channel. The guiding part includes an arc surface that can laterally contact the material to guide the material into the rejection channel.
[0008] Based on the above technical solution, the rejection unit includes rollers. The rejection unit is vertically movable above the rejection channel. When the rejection unit moves downwards and approaches the rejection channel, the rollers come into contact with the material to guide the material into the rejection channel.
[0009] Based on the above technical solution, the rejection unit includes an air nozzle facing the rejection channel to drive the material into the rejection channel.
[0010] Based on the above technical solution, the rejection unit can be moved up and down under the action of an external driving unit.
[0011] Based on the above technical solution, the rejection unit also includes a flow guide, which is designed to guide the airflow released by the blowing nozzle to the rejection channel.
[0012] Based on the above technical solution, the spacing between the multiple rejection units in the multi-rejection mechanism is adjustable.
[0013] Based on the above technical solution, the rejection channel is formed by the gap between two adjacent conveying length segments in the conveying assembly, or by the gap between the conveying assembly and the front end baffle.
[0014] Based on the above technical solution, the branching component includes multiple baffles arranged in parallel along the conveying direction, and the spacing between two adjacent baffles is adjustable to form a branching channel.
[0015] Based on the above technical solution, the conveying assembly includes several conveyor belts arranged in parallel and spaced apart. The conveyor belts are provided with several adsorption holes. The branching assembly includes a housing and a fan. Under the action of the fan, the inner cavity of the housing is in a negative pressure state. The contact surface of the housing that supports the upper conveyor belt is provided with several through holes so that the material adheres to the conveyor belt under the action of pressure difference.
[0016] Beneficial effects
[0017] In this invention, multiple rejection units in the multi-rejection mechanism can operate independently, thus rejecting defective materials on the corresponding branch and allowing good materials to continue to be conveyed forward, avoiding material waste.
[0018] In this embodiment, there are multiple rejection mechanisms and multiple rejection channels, with each rejection mechanism and channel corresponding to another. When there are two rejection mechanisms and two rejection channels, defective materials and good materials can be discharged from the two rejection channels respectively, automatically separating good and defective materials and significantly reducing manual screening. Furthermore, having multiple rejection mechanisms and multiple rejection channels ensures that subsequent material receiving components receive materials in the same quantity and at the same pace, facilitating unified packaging and bundling. This high degree of automation helps reduce labor costs. When there are three or more rejection mechanisms and rejection channels, in addition to the aforementioned effects, defective materials can be classified and collected, facilitating refined management of defective materials—a clever design.
[0019] In this invention, the rejection unit can be implemented in various ways to guide or drive the material downward into the rejection channel. In order to adapt to the material being conveyed, the spacing between multiple rejection units in the same multi-rejection mechanism can be adjusted, making it flexible to use.
[0020] In this embodiment, the diversion assembly may include multiple baffles arranged in parallel, forming a channel between the baffles for diversion and conveying, thus achieving diversion and conveying without interference; or the diversion assembly may include a housing and a fan, so that the material on the conveyor belt adheres to the conveyor belt under the action of pressure difference, thus achieving diversion and conveying of the material.

[0034] Example 1
[0035] like Figures 1-5 The material diversion and conveying mechanism shown includes a multi-rejection mechanism 2 and a diversion assembly 3 disposed near the conveying assembly 1.
[0036] In this embodiment, as Figure 2 and 3 As shown, the conveying assembly 1 includes two length sections, namely, two conveying units 11, which are spaced apart from each other. The gap between the two adjacent conveying units 11 can form a rejection channel a1. A guide plate is also provided below the rejection channel a1. The guide plate is inclined to guide the material passing through the rejection channel a1 to fall into a set area.
[0037] In addition, a vertically arranged baffle 4 is provided at the end of the conveying stroke of the conveying component 1. The baffle 4 is spaced apart from the conveying component 1, so that a conveying channel a2 can also be formed between the conveying component 1 and the baffle 4.
[0038] In this embodiment, the conveying unit away from the baffle 4 includes several conveying lines arranged along the conveying direction, and the conveying unit 11 near the baffle 4 includes several conveyor belts 111. The several conveyor belts 11 are arranged in the same direction and evenly spaced, thus conveying materials forward. In this embodiment, at least one conveyor belt 111 in the branch channel is provided with several adsorption holes 112, and the system also includes a housing 33 and a fan. Under the action of the fan, the inner cavity of the housing 33 is in a negative pressure state, which is prior art and will not be described in detail. The contact surface of the housing 33 that supports the upper conveyor belt 111 is provided with several through holes 331 so that the material adheres to the conveyor belt 111 under the action of pressure difference.
[0039] like Figure 4 As shown, the diversion assembly 3 is used to guide the material on the conveying assembly 1 forward along multiple diversion channels 300. In this embodiment, the diversion assembly 3 includes four baffles 31 arranged side by side above the conveying assembly 1 along the conveying direction. The distance between adjacent baffles 31 is adjustable and forms diversion channels 300. That is, the conveying assembly 1 is provided with three diversion channels 300, and the materials in the three diversion channels 300 are isolated from each other. The diversion assembly 3 also includes two fixed guide rails 32. The baffles 31 are slidably connected to the guide rails from the top to the left and right, such as setting the distance between adjacent baffles 31 to be adjustable.
[0040] like Figure 1 and 5As shown, in this embodiment, two rejection mechanisms 2 are respectively located above rejection channels a1 and a2 formed by the conveying assembly 1, and correspond one-to-one. In this embodiment, the two rejection channels a1 and a2 are arranged sequentially along the conveying direction of the conveying assembly 1, so that materials can selectively fall from rejection channel a1 or rejection channel a2. In other embodiments of this utility model, the rejection mechanisms 2 can also be located at the bottom of rejection channels a1 and a2 or in other positions. For example, if the rejection mechanisms 2 are located at the bottom of rejection channels a1 and a2, they can selectively suck the materials to be rejected into rejection channels a1 and a2 by adsorption, thus completing the rejection operation.
[0041] like Figure 1 As shown, the multi-rejection mechanism 2 includes three independently operating rejection units 21. The three rejection units 21 are set one-to-one with each branch channel 300 to drive the material on the corresponding branch channel 300 to fall from the rejection channels a1 and a2.
[0042] In this embodiment, as Figure 5 As shown, the multi-rejection mechanism 2 also includes a crossbar 22 and three connecting blocks 23. The crossbar 22 is fixed above the branch channel 300 and spans across the three branch channels 300. The three connecting blocks 23 are sleeved on the crossbar 22 and are slidably connected to the crossbar 22. A set screw passes through the connecting block 23 and abuts against the crossbar 22 to position the connecting block 23. In this way, the spacing between the three rejection units 21 is adjustable, which can be conveniently and flexibly adjusted according to the position of the branch channel 300.
[0043] Each connecting block 23 is equipped with a rejection drive 24. In this embodiment, the rejection drive 24 is a cylinder. In other embodiments of this utility model, the rejection drive 24 can be a hydraulic cylinder, an electric cylinder, a linear motor, a gear and rack transmission mechanism, a nut and screw mechanism, a motor belt transmission mechanism, or any other device capable of performing up-and-down reciprocating motion.
[0044] The rejection unit 21 includes a guide section, which includes an arc surface that can laterally contact the material. When the rejection drive 24 drives the guide section to move downward to cut off the branch channel 300, the front end of the material along the conveying direction contacts the guide section and then enters the rejection channels a1 and a2 under the guidance of the guide section, thereby dropping the material.
[0045] Work process
[0046] 1) The material enters from the inlet of the branch channel 300 and is transported forward; the external detection unit identifies the material and classifies good material into defective material and good material. The external detection unit's identification of the material and its distinction between defective and good material is existing technology and will not be elaborated here.
[0047] 2) When the material in one or two branch channels 300 is identified as defective material by the external detection unit, when the material travels to the rejection channel a1, the rejection unit 21 at the corresponding branch channel 300 moves downward, so that the defective material falls from the rejection channel a1; at the same time, the material in the branch channel 300 that is not identified as defective, i.e. good material, continues to be transported forward.
[0048] 3) When the material that is not identified as a defective product in the branch channel 300 continues to be transported to the next rejection channel a2, the rejection unit 21 in the multi-rejection mechanism 2 corresponding to the good product material rejects the good product material that is parallel to the defective product, and the good product material falls from the rejection channel a2.
[0049] In this way, the amount of material received from the end of the two branch channels 300 is always consistent, which facilitates subsequent bundling and packaging operations. At the same time, the setting of the two rejection channels a1 and a2 allows good materials to be collected separately from defective materials, avoiding manual sorting.
[0050] Example 2
[0051] The difference between Example 2 and Example 1 is that, as Figure 6 As shown, the conveying assembly 1 includes three or more length segments, that is, it includes three or more conveying units 11. The multiple conveying units 11 are arranged sequentially along the conveying direction. There are three or more rejection channels a1, a2, a3 formed between the conveying units 11 or between the conveying units 11 and the baffle 4.
[0052] When there are three rejection channels a1, a2, and a3, the external detection unit identifies the materials and can further subdivide the defective materials into two categories. The two categories of defective materials can be dropped from the two rejection channels a1 and a3 respectively, while the good materials can be dropped from the other rejection channel a2. In this way, the rejected materials are automatically classified and collected.
[0053] Correspondingly, when there are more rejection channels a1, a2, a3, the external inspection unit can further classify the defective materials into more categories.
[0054] The difference between Example 2 and Example 1 is that, as Figure 7 As shown, the conveying unit 11 includes several conveyor belts 111 arranged in parallel and spaced apart. Several adsorption holes 112 are provided on the conveyor belts 111. The branching assembly 3 includes a housing 33 and a fan. Under the action of the fan, the inner cavity of the housing 33 is in a negative pressure state. The contact surface of the housing 33 supporting the upper conveyor belt 111 is provided with several through holes 331 so that the material adheres to the conveyor belt 111 under the action of pressure difference. Multiple adsorption holes 112 arranged along the conveying direction form a branching channel 300. The material is transported forward on the conveyor belt 111 along the branching channel 300.
[0055] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
