[0034] The feeding mechanism is widely used to transport the finished products from the processing equipment to the next process or storage device. The traditional feeding mechanism usually relies on external power sources such as cylinders, motors, etc. to realize mechanical movement. The external power source usually also needs to be configured with corresponding detection switches or sensors to ensure the accuracy and reliability of the discharging process.

[0035] And with the development of magnetic drive technology, the conveying line based on magnetic force driving gradually becomes an important part of the new generation of automated production line. The magnetic drive conveying line uses magnetic force to convey materials without contact, which has the advantages of low noise, small wear, high energy efficiency, etc. Therefore, how to effectively apply the traditional discharging mechanism to the magnetic drive conveying line becomes a new challenge.

[0036] However, when applying the traditional feeding mechanism to the magnetic drive conveying line, the following problems will be encountered:

[0037] 1. Magnetic drive conveyor lines are typically designed to be compact to minimize interference from external equipment. Traditional discharge mechanisms require additional power sources such as cylinders and motors, which occupy extra space and complicate the overall layout, potentially interfering with the normal operation of the magnetic drive conveyor line.

[0038] 2. Traditional discharge mechanisms require additional control systems (such as switches and sensors), while magnetic drive conveyor lines already have integrated control logic. Adding an additional control system would increase the complexity of the control system and may not be compatible with the existing control system of the magnetic drive conveyor line; furthermore, maintenance costs would be relatively high.

[0039] 3. Traditional discharge mechanisms rely on external air or electricity, which increases the overall complexity and dependence on the external environment, making the stability and portability of the conveying system less than ideal. It also increases the cost of the conveying system.

[0040] For the above issues, please refer to Figure 1 , Figure 2 and Figure 3 This application relates to a conveying system 10, including a magnetically driven conveyor line, a feeding mechanism 100, and a material gripping mechanism 200. The magnetically driven conveyor line includes a conveyor body and a mover, which can move along the conveyor body under the magnetic force of the conveyor body. The conveyor body has a feeding station. The material gripping mechanism 200 can grip the material 300 conveyed by the feeding mechanism 100 and transfer it to the feeding station.

[0041] The conveyor line includes a stator. Current flows through the stator's coils to generate a magnetic field, which interacts with the magnetic field of the permanent magnet plate on the mover to induce motion. A position detection device obtains motion state data such as the mover's position and velocity and sends it to the control system. By controlling the current in the coils, the control system adjusts the strength and direction of the magnetic field to maintain the mover's desired position and velocity, thereby achieving precise control of the mover's motion.

[0042] Please see Figure 1 , Figure 2 and Figure 3 The feeding mechanism 100 includes a material storage housing 110 and a limiting component 120. The material storage housing 110 is used to store material 300 and has a material outlet pipe 111. The material 300 can flow to the outside through the material outlet pipe 111. The limiting component 120 is disposed on the material outlet pipe 111 and is used to limit the material outlet pipe 111 to prevent the material 300 from falling outside the material outlet pipe 111 when feeding is not required.

[0043] The limiting assembly 120 comprises a toggle lever 121 and a reset member 122. The toggle lever 121 is rotatably connected to the material outflow pipe 111. The toggle lever 121 protrudes towards the material outflow pipe 111 and forms a limiting protrusion 1211. The limiting protrusion 1211 can extend into or out of the material outflow pipe 111.

[0044] The toggle lever 121 has a limiting state and a release state. In the limiting state, the limiting protrusion 1211 can extend into the material outflow pipe 111 to limit the material 300 in the material outflow pipe 111, thereby preventing the material 300 from falling. In the release state, the limiting protrusion 1211 can extend out of the material outflow pipe 111 to not hinder the falling of the material 300.

[0045] The reset member 122 is arranged between the toggle lever 121 and the material outflow pipe 111. The reset member 122 is used to provide a reset force for the toggle lever 121 to tend to keep in the limiting state. In the embodiment, the reset member 122 is a spring.

[0046] The material grabbing mechanism 200 can move to the outlet of the material outflow pipe 111 and push the toggle lever 121 to switch to the release state, so that the material 300 flows out of the outlet of the material outflow pipe 111 to the material grabbing mechanism 200. The material grabbing mechanism 200 can also move to the material loading station to grab the material 300 onto the mover.

[0047] When the material grabbing mechanism 200 grabs the material 300, the material grabbing mechanism 200 pushes the toggle lever 121 to move, so as to switch the toggle lever 121 from the limiting state to the release state. After the material 300 falls, the material grabbing mechanism 200 can grab the material 300 and transfer the grabbed material 300 to the material loading station. After the material grabbing mechanism 200 moves away, the toggle lever 121 switches from the release state to the limiting state under the reset force of the reset member 122, thereby limiting the material 300 in the material outflow pipe 111.

[0048] The application omits an additional power source and an additional control system, saves space, simplifies the overall layout, reduces interference with the magnetic drive conveying line, ensures normal operation of the magnetic drive conveying line, reduces the complexity and maintenance cost of the control system, reduces the overall complexity and dependence on the external environment, improves the overall stability and portability, and reduces the overall cost.

[0049] Please refer to Figure 1 , Figure 2 and Figure 3According to some embodiments of the present application, optionally, a mounting groove is formed on the sidewall of the material outflow pipe 111, and the mounting groove is in communication with the interior of the material outflow pipe 111. One end of the poking rod 121 is hingedly connected to the mounting groove, and the other end of the poking rod 121 extends outside the material outflow pipe 111, so as to facilitate the poking of the material grabbing mechanism 200. In the limiting state, the extension direction of the poking rod 121 is parallel to the extension direction of the material outflow pipe 111.

[0050] Specifically, the poking rod 121 is provided with a through hole, and the rotating shaft 125 is arranged in the through hole, and the two ends of the rotating shaft 125 are respectively connected to the two sidewalls of the mounting groove.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 According to some embodiments of the present application, optionally, the poking rod 121 has a first sidewall and a second sidewall arranged opposite to each other, and the limiting protrusion 1211 is protruded from the first sidewall. The limiting assembly 120 further comprises a limiting piece 123 arranged on the sidewall of the mounting groove, and the limiting piece 123 is arranged opposite to the first sidewall. The limiting piece 123 can abut against the first sidewall of the poking rod 121 to limit the poking rod 121. Specifically, the two ends of the limiting piece 123 are connected to the two sidewalls of the mounting groove.

[0052] When the poking rod 121 is switched from the releasing state to the limiting state, the first sidewall of the poking rod 121 can abut against the limiting piece 123, and the limiting piece 123 can limit the position of the poking rod 121 to prevent the poking rod 121 from rotating excessively.

[0053] Please refer to Figure 1 , Figure 2 and Figure 3 According to some embodiments of the present application, optionally, the poking rod 121 further comprises a limiting groove 124 formed on the first sidewall, and the limiting piece 123 can be embedded in the limiting groove 124. Specifically, the outer contour of the limiting piece 123 is matched with the shape of the inner contour of the limiting groove 124.

[0054] By arranging the limiting groove 124, the distance between the limiting piece 123 and the poking rod 121 can be reduced while ensuring the swing range of the poking rod 121, so that the overall structure is more compact and occupies less area.

[0055] Please refer to Figure 1 , Figure 2 and Figure 3According to some embodiments of the present application, optionally, the second side wall of the toggle lever 121 is provided with a reset slot 1212, a reset member 122 is arranged in the reset slot 1212, and the two ends of the reset member 122 are respectively connected to the outer side walls of the material outflow pipe 111 on the two sides of the mounting slot. Specifically, the reset member 122 abuts in the reset slot 1212, and provides a reset force for the toggle lever 121 to tend to keep in the limiting state.

[0056] The two side edges of the mounting slot are protruded towards the outer side walls of the material outflow pipe 111 to form two mounting portions. Specifically, the two ends of the reset member 122 are respectively connected to the outer side walls of the two mounting portions. The two ends of the rotating shaft 125 and the limiting member 123 are respectively connected to the side walls of the two mounting portions.

[0057] It should be noted that the reset member 122 provides a reset force for the toggle lever 121 to tend to keep in the limiting state in the limiting state and the release state. In the limiting state, the reset force of the reset member 122 is greater than the gravity of the material 300 pressing on the limiting protrusion 1211, so as to include the limiting effect of the limiting protrusion 1211. In the release state, the force applied by the material grabbing mechanism 200 to the toggle lever 121 is greater than the reset force of the reset member 122, and after the force applied by the material grabbing mechanism 200 to the toggle lever 121 disappears, the toggle lever 121 returns to the release state under the reset force of the reset member 122.

[0058] Please refer to Figure 1 、 Figure 2 and Figure 3 According to some embodiments of the present application, optionally, the feeding mechanism 100 further comprises a mounting bracket 130 connected to the material storage shell 110 and a bearing column 140 arranged on the mounting bracket 130. The bearing column 140 is located directly below the material outflow pipe 111, and the bearing column 140 has a bearing surface for bearing the material 300 flowing out of the material outflow pipe 111. The material 300 flowing out of the material outflow pipe 111 will fall onto the bearing surface.

[0059] The mounting bracket 130 comprises a connecting portion 131, a vertical portion 132 and a horizontal bottom plate 133. The connecting portion 131 is connected to the outer side wall of the material outflow pipe 111, the vertical portion 132 is connected between the connecting portion 131 and the horizontal bottom plate 133. The bearing column 140 is arranged on the horizontal bottom plate 133, and the extension direction of the bearing column 140 is flush with the extension direction of the vertical portion 132.

[0060] Please refer to Figure 1 、 Figure 2 and Figure 3According to some embodiments of the present application, the height of the material 300 is H1. The distance between the bearing surface and the material outflow pipe 111 is H2. The distance between the limiting protrusion 1211 and the bearing surface is H3, and H2

[0061] It should be noted that the height of the material 300, the distance between the bearing surface and the material outflow pipe 111, and the distance between the limiting protrusion 1211 and the bearing surface are not specifically limited and can be set according to actual use requirements. In this embodiment, only one material 300 is allowed to flow out of the material outflow pipe 111 at a time. When one of the materials 300 falls onto the bearing surface, the material 300 adjacent thereto is located in the material outflow pipe 111, and the limiting protrusion 1211 is located between the two materials 300 to limit the material 300 located in the material outflow pipe 111.

[0062] Please refer to Figure 1 , Figure 2 and Figure 3 According to some embodiments of the present application, the feeding mechanism 100 further comprises a material detection module 150, which is used to detect whether there is a material 300 on the bearing surface. Specifically, the bearing surface is provided with a detection hole, and the bearing column 140 is provided with a mounting chamber for mounting the material detection module 150, which is in communication with the detection hole. Exemplarily, the material detection module 150 adopts an in-place detection photoelectricity. The light emitted by the light emitter of the in-place detection photoelectricity is emitted through the detection hole.

[0063] The conveying system 10 further comprises a control module for realizing automatic control. The control module is connected with the material detection module 150 and the material grabbing mechanism 200. The material detection module 150 is used to detect whether there is a material 300 on the bearing surface. When the material detection module 150 detects that there is a material 300 on the bearing surface, the control module controls the material grabbing mechanism 200 to grab the material 300 on the bearing surface and grab the material 300 onto the mover on the feeding station.
