For a linear conveyor system, it can only move linearly, and different linear conveyor systems can only be connected by an arc-shaped conveyor line, but it occupies a large space in the workshop. There is a technical solution that provides a rotatable transfer component capable of transferring the mover between two magnetic drive conveyor lines.

[0048] Please refer toFigures 1-6 , an embodiment of the present application provides a ferry mechanism disposed between multiple sets of conveyor lines 10.

[0049] Please refer to Figures 1-3 , the conveyor line 10 has a first stator 101 and a first mover 102. The first stator 101 can provide a magnetic field to drive the first mover 102, so that the first mover 102 moves along the extending direction of the first stator 101. The ferry mechanism is used to switch the first mover 102 on one set of conveyor lines 10 to another set of conveyor lines 10.

[0050] The ferry mechanism includes multiple workstations, a rotating assembly 100, and a second stator 200. The rotating assembly 100 is configured to rotationally drive the second stator 200 to move between multiple workstations. The multiple workstations respectively correspond to each set of conveyor lines 10 one by one. The second stator 200 is used to generate a magnetic field to drive the first mover 102. The second stator 200 at the workstation is collinear with the first stator 101 of the conveyor line 10, so that the first mover 102 can move to the second stator 200 or move from the second stator 200 to the first stator 101 on the conveyor line 10.

[0051] Among the multiple workstations, there are a first workstation and a second workstation. The conveyor line 10 corresponding to the first workstation and the conveyor line 10 corresponding to the second workstation are parallel to each other and have opposite conveying directions. The second stator 200 is disposed on the rotating assembly 100 and is eccentric to the rotation axis of the rotating assembly 100, so that it can swing to the first workstation or the second workstation.

[0052] In the above embodiment, the rotating assembly 100 can rotationally drive the second stator 200 to move between multiple workstations. The second stator 200 at the workstation is collinear with the first stator 101 of the corresponding conveyor line 10, so that the first mover 102 can move from the conveyor line 10 to the second stator 200 or move out of the second stator 200 to the first stator 101 on the conveyor line 10. By disposing the second stator 200 on the rotating assembly 100 and being eccentric to the rotation axis of the rotating assembly 100, the second stator 200 can be driven to the first workstation and the second workstation, thereby switching the first mover 102 on two parallel conveyor lines 10 with opposite conveying directions, so that the material is conveyed within a relatively concentrated space, reducing the floor area of the conveyor line 10 in the workshop, facilitating the efficient use of the workshop space, and making the production layout more compact and reasonable.

[0053] In order to prevent the first mover 102 from moving out of the second stator 200 during the process of the rotating component 100 driving the second stator 200 to swing, in some embodiments, the ferry mechanism includes a limiting component. The limiting component is disposed on the second stator 200 and has an open state and a locked state. In the locked state, at least a part of the limiting component is in the moving path of the first mover 102 to prevent the first mover 102 from moving out of the second stator 200. In the open state, the limiting component is outside the moving path of the first mover 102.

[0054] When the first mover 102 needs to move to the second stator 200, the limiting component is in the open state; when the first mover 102 is in the second stator 200 and swings with the second stator 200, at this time the limiting component is in the locked state to prevent the first mover 102 from moving out of the second stator 200; when the first mover 102 needs to move out of the second stator 200, the limiting component is in the open state.

[0055] Taking the example that multiple workstations only include the first workstation and the second workstation, the structure of the limiting component will be further described below.

[0056] Please refer to Figures 4-6 , in some embodiments, the limiting component includes a first limiting member 310 and a second limiting member 320. The first limiting member 310 and the second limiting member 320 are rotatably disposed on the second stator 200. In some specific embodiments, the second stator 200 includes a stator body 210 and a connecting block. The connecting block is disposed on the stator body 210, and the connecting block has a rotating shaft. The first limiting member 310 is inserted through the rotating shaft, thereby realizing the rotational connection with the second stator 200.

[0057] There is a gap between the first limiting member 310 and the second limiting member 320 for accommodating at least a part of the first mover 102. Specifically, the first mover 102 includes a mover body and a stopper. The stopper is connected to the mover body and partially extends downward beyond the mover body. The extended part is between the first limiting member 310 and the second limiting member 320. When both the first limiting member 310 and the second limiting member 320 are in the locked state, the movement of the stopper is restricted by the first limiting member 310 and the second limiting member 320. Both the first limiting member 310 and the second limiting member 320 have a torque to maintain the locked state. It should be noted that when the first limiting member 310 or the second limiting member 320 is in the open state, the limiting component is in the open state. When the first limiting member 310 and the second limiting member 320 are in the locked state, the limiting component is in the locked state.

[0058] The limiting component includes a first support member 330 and a second support member 340. The first support member 330 is located below the first working position and is configured to cooperate with the first limiting member 310 to cause the first limiting member 310 to rotate against the torque to the open state. That is to say, when the second stator 200 rotates to the first working position, at this time, the first support member 330 cooperates with the first limiting member 310 to cause the first limiting member 310 to rotate against the torque to the open state, so as to facilitate the movement of the first mover 102 on the first stator 101 to the second stator 200.

[0059] The second support member 340 is located below the second working position and is configured to cooperate with the second limiting member 320 to cause the second limiting member 320 to rotate against the torque to the open state. That is to say, when the second stator 200 rotates to the second working position, at this time, the second support member 340 cooperates with the second limiting member 320 to cause the second limiting member 320 to rotate against the torque to the open state, so as to facilitate the movement of the first mover 102 on the second stator 200 to the first stator 101.

[0060] Please refer to Figure 4 and Figure 5 , in some embodiments, the first limiting member 310 includes a first part 311 and a second part 312. The first part 311 and the second part 312 are distributed on both sides of the rotation axis of the first limiting member 310. The first part 311 can extend into the moving path of the first mover 102, and the second part 312 can cooperate with the first support member 330. Specifically, a through hole for the rotation shaft to pass through is provided at the connection between the first part 311 and the second part 312. When the first part 311 moves downward, the protruding part moves upward to enter the moving path of the first mover 102. When the first part 311 moves upward, the protruding part moves downward to exit the moving path of the first mover 102.

[0061] Under the action of gravity, the torque of the second part 312 is greater than the torque of the first part 311, so that the first part 311 is kept extending into the moving path of the first mover 102. Among them, the magnitudes of the torques of the second part 312 and the first part 311 are affected by their weights on the one hand and the distances between their centers of gravity and the rotation axis on the other hand.

[0062] In some embodiments, the first limiting member 310 further includes an elastic member. The first part 311 is connected to the elastic member, and the elastic member is used to provide an elastic force to keep the first part 311 extending into the moving path of the first mover 102, so that the first limiting member 310 remains in the locked state.

[0063] Among them, the torque can also be provided jointly by the second part 312 and the elastic member, thereby improving the stability of the locked state.

[0064] Among them, the second limiting member 320 may also include a first portion 311 and a second portion 312. The first portion 311 and the second portion 312 are distributed on both sides of the rotation axis of the second limiting member 320. Specifically, it may adopt the same structure and layout as the first limiting portion, which will not be elaborated here.

[0065] Please refer to Figure 5 , in some embodiments, the second portion 312 of the first limiting member 310 has a first roller 3121. The top surface of the first support member 330 is a wedge surface 331. The wedge surface 331 and the first roller 3121 partially overlap in the height direction. The first roller 3121 is configured to roll on the wedge surface 331 to drive the first limiting member 310 to rotate to the open state, or roll in the reverse direction to make the first limiting member 310 rotate in the reverse direction to the locked state. Specifically, during the swinging of the second stator 200, the first limiting member 310 follows the swinging. When the first limiting member 310 contacts the first support member 330, the first roller 3121 contacts the lower end of the wedge surface 331. Continuing to swing, the first roller 3121 rolls on the wedge surface 331 and gradually rises to overcome the torque, so that the protruding portion gradually descends and exits the moving path of the first mover 102. On the contrary, during the reverse swinging of the second stator 200, when the first limiting member 310 exits the first support member 330, the first roller 3121 moves in the reverse direction and gradually descends under the action of the torque, and the protruding portion gradually rises and extends into the moving path of the first mover 102.

[0066] Similarly, the second portion 312 of the second limiting member 320 may also have a first roller 3121. The top surface of the second support member 340 may be the wedge surface 331, and the two cooperate with each other to complete the switching between the locked state and the open state.

[0067] Please refer to Figure 4 , in some embodiments, a support plate 500 is provided on the rotating assembly 100. The second stator 200 is disposed on the support plate 500. Along the rotation axis, the second stator 200 is partially misaligned with the rotating assembly 100 and is suspended.

[0068] Please refer to Figure 5 and Figure 6 , in some embodiments, the ferry mechanism includes a support assembly 400. The support assembly 400 includes a mounting bracket 420 and a second roller 410. The second roller 410 is rotatably disposed on the mounting bracket 420. When the second stator 200 is in the working position, the support roller can support on the second stator 200 to support the suspended part, thereby meeting the requirement of collinearity. And the second roller 410 is a rolling support, so the friction is small and it will not hinder the swinging of the second stator 200.

[0069] Among them, the bottom of the second stator 200 can be disposed on the corresponding support block 240 of the second roller 410. Both ends of the support block 240 form guiding slopes so as to guide the second roller 410 to be supported on the support block 240.

[0070] Please refer to Figure 4 , in some embodiments, it further includes limit stoppers 600 disposed at both ends of the swinging stroke of the second stator 200 for limiting the extreme swinging stroke of the second stator 200. It further includes a sensor assembly 700. The sensor assembly 700 includes sensors and sensing pieces. The sensing pieces are disposed on the second stator 200 and swing along with the second stator 200. There are specifically multiple sensors respectively disposed at each station for obtaining the in-place information of the sensing pieces.

[0071] Please refer to Figures 4-6 , in some embodiments, the second stator 200 includes a stator body 210 and an armature winding 220. The armature winding 220 can be magnetically cooperated with the first mover 102. The armature winding 220 is disposed on the stator body 210 and located on the outer side surface of the stator body 210. Among them, the outer side surface is the side surface of the stator body 210 facing away from the rotation axis, thus reducing the width dimension of the stator body 210, and further reducing the spatial requirement for arrangement.

[0072] In some embodiments, the second stator 200 includes a guide rail 230 disposed on the outer side surface of the stator body 210. The first mover 102 includes a slider which is slidably cooperated with the guide rail 230.

[0073] It should be noted that when the number of the conveying lines 10 is three or more, there will be a gap between the second stator 200 at the middle station of the swinging path and the corresponding conveying line 10.

[0074] In order to eliminate the above-mentioned gap, in some embodiments, the ferry mechanism includes a translation assembly. The translation device is configured to be able to drive the second stator 200 to translate close to the conveying line 10 so as to eliminate the above-mentioned gap. Or drive the second stator 200 to translate away from the conveying line 10 so that there is a gap between the second stator 200 and the corresponding conveying line 10, facilitating the continuous swinging and passing of the second stator 200.

[0075] In some specific embodiments, the ferry mechanism includes a mounting base. The rotating assembly 100 is disposed on the mounting base. The translation assembly is disposed on the rotating assembly 100 and driven by the rotating assembly 100. The second stator 200 is disposed on the translation assembly and driven by the translation assembly.

[0076] The embodiment of the present application further provides a magnetic drive conveyor line 10, which includes a ferry mechanism and a plurality of conveyor lines 10. Among them, two conveyor lines 10 are arranged in parallel, and the ferry mechanism is arranged at one end of the two parallel conveyor lines 10. In this way, the material is conveyed in a relatively concentrated space, reducing the floor area of the conveyor line 10 in the workshop.

[0077] In some embodiments, the conveyor line 10 has a first stator 101 and a first mover 102. The first mover 102 includes a mover body and a permanent magnet part. The permanent magnet part is arranged on the mover body and is configured to be magnetically driven by the first stator 101 or the second stator 200.

[0078] Among them, the mover body includes a mounting plate body 1021 and a load-carrying plate body 1022 which are connected to each other. The mounting plate body 1021 is used for mounting the permanent magnet part, and the mounting plate body 1021 can be opposite to the outer side surface of the second stator 200. The load-carrying plate body 1022 is used for carrying materials and can be opposite to the top surface of the second stator 200. In this way, the space at the top of the second stator 200 can be fully utilized, improving the space utilization rate.

[0079] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
