Fig. 1, 2, 3 and 4 show a stopper 1 according to a first embodiment of the invention, and fig. 7 shows a conveyor line according to an embodiment of the invention. The stopper 1 is used for blocking a rotor 5 on the switching track, the conveying line comprises two fixed tracks and two connecting tracks 2, the two fixed tracks are a first fixed track 3 and a second fixed track 4 respectively, and the connecting tracks 2 are switched between a first position and a second position; the connection track 2 is in butt joint with the first fixed track 3 when the connection track 2 is in the first position, and the connection track 2 is in butt joint with the second fixed track 4 when the connection track 2 is in the second position. The mover 5 is transported on a track. The fixed rail and the connection rail 2 can be magnetic drive rails, and the mover 5 moves along the switching rails under the action of magnetic force. In some circumstances it is necessary to transplant the mover 5 onto another track and therefore to dock the track 2. For example, if it is desired to transfer the mover 5 on the first fixed rail 3 to the second fixed rail 4, then it is desired to bring the docking rail 2 into docking communication prior to the first fixed rail 3 so that the mover 5 on the first fixed rail 3 can slide into the docking rail 2; after the mover 5 enters the connection track 2, the mover 5 can move along with the connection track 2 by moving the connection track 2; next, the docking rail 2 is in docking communication with the second fixed rail 4, such that the mover 5 on the docking rail 2 can slide onto the second fixed rail 4. At this time, the operation of transplanting the mover 5 on the first fixed rail 3 to the second fixed rail 4 is completed.

Referring to fig. 7 and 8, the docking rail 2, the first fixed rail 3, the second fixed rail 4 and the stopper 1 are included, the first fixed rail 3 and the second fixed rail 4 are arranged in parallel, and the docking rail 2 is arranged on each of the first fixed rail 3 and the second fixed rail 4. Through parallel first fixed track 3 and second fixed track 4 and two track 2 that connect to with two track 2 that connect form annular magnetism and drive the track with two track 2 that connect at the both ends of first fixed track 3 and second fixed track 4, through at the both ends of first fixed track 3 or active cell 5 exit end, the both ends of second fixed track 4 or active cell 5 exit end set up stopper 1, set up transfer line 12 on two track 2 that connect to prevent to drop of active cell 5 in the transportation.

Regarding the connection track, install on a translation track, set up drive arrangement on the translation track and drive connection track 2 translation in the second horizontal direction and realize the butt joint with the fixed track. The specific driving device can drive the docking track by adopting a linear motor.

The stopper 1 blocks the mover 5 from passing when the first or second fixed rail 3 or 4 is not docked with the docking rail 2, and can allow the mover 5 to pass into the docking rail 2 when the first or second fixed rail 3 or 4 is docked with the docking rail 2.

Referring to fig. 5, 6 and 7, the stopper 1 includes: the blocking component 11 and the transmission rod 12 are respectively arranged on the first fixed rail 3 and the second fixed rail 4; the blocking assembly 11 comprises a mounting seat 111 and a blocking mechanism 112, the mounting seat 111 is mounted on the first fixed rail 3 or the second fixed rail 4, and the blocking mechanism 112 is mounted on the mounting seat 111; the blocking mechanism 112 has a blocking position that prevents the mover 5 from passing therethrough and a passing position that passes the mover 5 therethrough. The blocking component 11 is disposed on the first fixed rail 3 or the second fixed rail 4, for example, the blocking component 11 disposed on the first fixed rail 3, and the blocking mechanism 112 may extend upwards out of the blocking block 1122 to form a blocking position when the docking rail 2 is docked with the first fixed rail 3, so that the blocking block 1122 forms a blocking on the mover 5 at one side of the first fixed rail 3, so that the mover 5 cannot pass through. When the docking rail 2 and the first fixed rail 3 are disengaged, the blocking mechanism 112 retracts the protruding blocking block 1122 downward to form a passing position so that the mover 5 can pass. The blocking assembly 11 on the second fixed rail 4 is similar in structure to the first rail.

The transmission rod 12 is arranged on the connection track 2; the transmission rod 12 can be fixedly connected with the connection track 2, no extra power is needed, and the transmission rod only needs to move along with the movement of the connection track 2 when being in butt joint with other tracks. When the connection track 2 is displaced to the first position, the transmission rod 12 drives the blocking mechanism 112 on the first fixed track 3 to switch to the passing position; wherein when the docking rail 2 moves towards the first fixed rail 3 and is docked, the transmission rod 12 also moves along with the docking rail 2, and in the process of moving the transmission rod 12, the transmission rod 12 drives the blocking mechanism 112, so that the blocking mechanism 112 is shifted from the blocking position to the passing position, and when the docking rail 2 is docked with the first fixed rail 3, the blocking mechanism 112 is in the blocking position when the docking rail 2 is docked with the first fixed rail 3 and is located at the first position. When the connection track 2 leaves the first position, the blocking mechanism 112 on the first fixed track 3 is reset to the blocking position; when the docking rail 2 is moved away from the first fixed rail 3, the transmission rod 12 moves along with the docking rail 2, and at this time, the blocking mechanism 112 is switched to the blocking position. When the connection track 2 is displaced to the second position, the transmission rod 12 drives the blocking mechanism 112 on the second fixed track 4 to switch to the passing position; when the docking rail 2 leaves the second position, the blocking mechanism 112 on the second fixed rail 4 is reset to the blocking position.

The blocking mechanism 112 includes: a blocking block 1122 and a follower lever 1121, the blocking block 1122 being for blocking passage of the mover 5; the follower rod 1121 is slidably connected to the mounting base 111, and the stopper 1122 is mounted on one end of the follower rod 1121; when the transmission rod 12 drives the blocking mechanism 112 to switch to the passing position, the transmission rod 12 drives the follower rod 1121 to slide. The follower lever 1121 is driven by the transmission lever 12 so that the passing position is switched by sliding of the follower lever 1121. Specifically, when the docking rail 2 is docked, the transmission rod 12 moves along with the docking rail 2, so as to drive the follower rod 1121 to slide, wherein the follower rod 1121 preferably slides downward, and the follower rod 1121 slides to drive the blocking block 1122 to move downward, so that the blocking mechanism 112 is switched to the passing position by releasing the blocking of the mover 5. After the docking rail 2 is undocked and the transfer rod 12 is moved away from the follower rod 1121, the blocking mechanism 112 automatically resets to the blocking position.

The resetting mode may be gravity resetting, for example, a lever is arranged on the mounting seat 111, one end of the lever is connected with the follower rod 1121, the other end of the lever is provided with a balancing weight, and the follower rod 1121 and the blocking block 1122 are moved upwards by gravity to be switched to the blocking position. A return spring 113 may be used for return.

The blocking mechanism 112 further comprises a follower wheel 1123, the follower wheel 1123 is mounted on the follower rod 1121, and the transmission rod 12 is provided with an inclined surface 121; when the transmission rod 12 drives the blocking mechanism 112 to switch to the passing position, the inclined surface 121 presses the follower wheel 1123. By providing the inclined surface 121 on the transmission rod 12, providing the follower wheel 1123 on the follower rod 1121, when the docking movement is performed on the docking rail 2, the inclined surface 121 on the transmission rod 12 presses the follower wheel 1123, so that the follower wheel 1123 rolls along the inclined surface 121, thereby driving the follower rod 1121 to move downwards, further driving the blocking piece 1122 to move downwards, and releasing the blocking of the mover 5 to switch to the passing position. Specifically, two inclined surfaces 121 are respectively disposed at two ends of the transmission rod 12, one inclined surface 121 is used for driving the blocking mechanism 112 on the first fixed rail 3, and the other inclined surface 121 is used for driving the blocking mechanism 112 on the second fixed rail 4.

The transmission rod 12 moves in the horizontal direction following the docking rail 2, and the follower rod 1121 moves in the vertical direction, with the angle between the inclined surface 121 and the horizontal surface being not more than 45 °. The driving rod 12 moves the following rod 1121 through the inclined surface 121 and the following wheel 1123, the driving rod 12 moves in the horizontal direction, and the following rod 1121 moves in the vertical direction, so that the included angle between the inclined surface 121 and the horizontal plane is not easy to be excessively large, and when the included angle between the inclined surface 121 and the horizontal plane is excessively large, the following wheel 1123 receives larger horizontal force, so that the following rod 1121 needs to bear larger bending load, and even the following wheel 1123 is blocked and cannot slide

The stopper 1 further includes a stopper 13, where the stopper 13 is connected to the mounting base 111, and the stopper 13 is used to limit the moving height of the follower rod 1121 so that the axis of the follower wheel 1123 is not higher than the upper edge of the inclined surface 121. The stopper 13 is provided to restrict the upward movement of the follower lever 1121, and prevent the follower wheel 1123 from rising too high. When the axial center of the follower 1123 rises to a height exceeding the upper edge of the inclined surface 121, the transmission rod 12 is locked between the follower 1123, so that the follower 1123 cannot be pushed down, and the stopper 1122 cannot be retracted.

The barrier 1 further includes a cushion pad 14, the cushion pad 14 being coupled to a side surface of the barrier 1122 facing the mover 5, the cushion pad 14 having elasticity. Specifically, the cushion pad 14 is provided on the surface of the stopper 1122 for blocking the mover 5. When the mover 5 slides and is blocked by the blocking block 1122, the sliding block receives a large impact force, which may damage the blocking member 11, and thus the cushion pad 14 is provided on the blocking block 1122 on a plane for blocking the mover 5, absorbing the impact force, thereby protecting the blocking member 11 from the impact force. Wherein the cushion pad 14 may be made of rubber, sponge, etc.

The stopper 1 further comprises a sensor 15, the sensor 15 being mounted on the mounting 111, the sensor 15 being arranged to detect whether the blocking member 1122 is in place when the blocking mechanism 112 is in the passing or blocking position. Specifically, the sensor 15 includes a sensing piece 151, a first photoelectric switch 152, and a second photoelectric switch 153; the sensing piece 151 is disposed on the follower lever 1121, and the sensing piece 151 is used for being sensed by the first photoelectric switch 152 and the second photoelectric switch 153; when the blocking piece 1122 is located at the blocking position, the sensing piece 151 is sensed by the first photoelectric switch 152; when the stopper 1122 is located at the passing position, the sensing piece 151 is sensed by the second photoelectric switch 153. When the sensing piece 151 moves along with the blocking block 1122, the sensing piece 151 blocks the first photoelectric switch 152, and the sensing piece is sensed by the first photoelectric switch 152, so as to indicate that the blocking block 1122 is in place at the blocking position. When the sensing piece 151 shields the second photoelectric switch 153, the sensing piece is sensed by the second photoelectric switch 153, which indicates that the blocking piece 1122 is in place at the passing position.

The blocking assembly 11 further comprises a return spring 113, one end of the return spring 113 is connected with the mounting seat 111, the other end of the return spring 113 is connected with the blocking mechanism 112, and the return spring 113 is used for driving the blocking mechanism 112 to return to the blocking position. The reset spring 113 is adopted for resetting, so that the structure is simpler, and the resetting is quicker.
