Referring to fig. 1, the present invention provides a material handling apparatus (not shown) and a stopping device 10, wherein the material handling apparatus includes the stopping device 10.

The material handling device may be a transfer vehicle, a logistics transportation line, an agv (automated Guided vehicle), or other device capable of handling materials. The material handling equipment is provided with a conveying line for conveying materials, and the conveying line can be one layer or multiple layers. For a double-layer AGV, the conveying line includes an upper roller conveying line and a lower roller conveying line.

The stop 10 is used to prevent material to be handled from sliding off the end of the conveying line of the material handling apparatus. Specifically, the shift stop device 10 has a shift stop state and an avoidance state. When materials to be conveyed are fed to a conveying line, the stopping device 10 can be switched to a stopping state, so that the conveyed materials can be prevented from sliding off from the tail end of the conveying line due to inertia; when the materials to be carried are discharged from the conveying line, the blocking device 10 can be switched to the avoiding state so as to facilitate discharging.

Referring to fig. 2, the stopping device 10 in the preferred embodiment of the present invention includes a driving mechanism 100, a transmission mechanism 200 and a blocking mechanism 300.

The driving mechanism 100 is used for providing power, and may be composed of a motor, a cylinder, an electric cylinder, and other power elements and their mating elements. The transmission mechanism 200 may be a shaft transmission mechanism, a chain transmission mechanism or a belt transmission mechanism, and is used for outputting the power of the driving mechanism 100 to the blocking mechanism 300 to drive the blocking mechanism 300 to act, so as to realize the switching between the gear stop state and the avoiding state.

The blocking mechanisms 300 are at least two and are arranged on two opposite sides of the conveying line. Specifically, the blocking mechanism 300 may be mounted to the side of the frame of the AGV. For the material handling apparatus described above, the blocking mechanisms 300 are disposed on opposite sides of each layer of the conveying line. Taking the stopping device 10 for a double-layered AGV cart shown in fig. 1 as an example, four stopping mechanisms 300 are provided since the double-layered AGV has two layers of conveying lines. Wherein, a blocking mechanism 300 is respectively arranged at the left side and the right side of each layer of conveying line. Of course, for other materials handling devices having a greater number of tiers, the number of blocking mechanisms 300 may be increased as desired.

Further, each blocking mechanism 300 includes a stop 310. When the stopping piece 310 extends into the conveying line, the material can be prevented from sliding off the conveying line, so that the stopping mechanism 300 is in a stopping state; when the blocking member 310 is moved out of the conveying line, the blocking mechanism 300 is in the retracted state. At least two blocking mechanisms 300 are in transmission connection with the driving mechanism 100 through the transmission mechanism 200. Under the driving of the driving mechanism 100, at least two blocking mechanisms 300 can be switched between the gear stop state and the avoidance state.

The driving mechanism 100 transmits power to at least two blocking mechanisms 300 through the transmission mechanism 200, so that the driving mechanism 100 is provided separately from the blocking mechanisms 300. Since the space occupied by a single blocking mechanism 300 is relatively small. Further, when the blocking mechanism 300 is in the retracted state, the stopper 310 is located outside the transmission line, and only when the blocking mechanism 300 is switched to the stopper state, the stopper 310 needs to be inserted into the transmission line. Therefore, the stop device 10 is suitable for being arranged in a narrow space.

In the present embodiment, the driving mechanism 100 and at least two blocking mechanisms 300 are distributed along a predetermined path, and each blocking mechanism 300 is connected with the adjacent blocking mechanism 300 and/or the driving mechanism 100 through the transmission mechanism 200.

Specifically, the blocking mechanisms 300 connected to each other can be interlocked with each other. Therefore, the driving mechanism 100 may not be connected to all of the blocking mechanisms 300, but may be directly connected to only a part of the blocking mechanisms 300. The driving mechanism 100 directly drives the blocking mechanism 300 connected with the driving mechanism to act, and can indirectly drive the rest blocking mechanisms 300 to act through the part of the blocking mechanisms 300. As such, the plurality of blocking mechanisms 300 are more synchronized. Moreover, the blocking mechanism 300 can also function as a transmission, so the structure of the transmission mechanism 200 can be significantly simplified, and the structure of the stop device 10 is simpler.

The direct driving means that the output end of the driving mechanism 100 is directly connected to the blocking mechanism 300, or transmits power to the driving blocking mechanism 300 through a transmission structure such as a belt and a gear, and the indirect driving means that the blocking mechanism 300 acts under the action of other blocking mechanisms 300.

Taking the stop device 10 shown in fig. 1 as an example, the driving mechanism 100 and the at least two blocking mechanisms 300 are arranged according to a U-shaped predetermined path, the driving mechanism 100 is located in the middle of the predetermined path, the driving mechanism 100 is connected to the upper and left blocking mechanisms 300, respectively, and the upper and left blocking mechanisms 300 are connected to one blocking mechanism 300, respectively. Thus, the driving mechanism 100 can directly drive the two blocking mechanisms 300 connected thereto to operate, and the two blocking mechanisms 300 can respectively drive the other two blocking mechanisms 300 to operate.

In the present embodiment, the transmission mechanism 200 includes a transmission belt 210, and the blocking mechanisms 300 and the transmission mechanism 200 and two adjacent blocking mechanisms 300 are connected by the transmission belt 210.

In particular, the belt 210 may be a common timing belt, belt. Two adjacent blocking mechanisms 300, and the blocking mechanism 200 and the adjacent driving mechanism 100 are connected through a transmission belt 210, so that transmission is realized. The transmission belt 210 is a flexible transmission member, and can adjust the extending direction and the angle according to the positions of the driving mechanism 100, the transmission mechanism 200, and the blocking mechanism 300, thereby facilitating the layout of the stop device 10.

Further, in the present embodiment, the driving mechanism 100 includes a base 110, a motor 120, and a rotating shaft 130. Wherein:

the base 110, which supports, may be secured to the frame of the AGV. The motor 120 is fixed to the motor 120 of the base 110. The rotation shaft 130 is rotatably provided to the base 110 and coupled to the motor 120. Specifically, the base 110 may be provided with a rotation support seat 111 and a motor mounting seat 112, and the rotation shaft 130 and the motor 120 are mounted through the rotation support seat 111 and the motor mounting seat 112, respectively. The rotating shaft 130 and the motor 120 may be connected by a coupling (not shown) to output the torque of the motor 120.

Two first transmission wheels 131 are disposed along the axial direction of the rotating shaft 130, and the transmission belt 210 can be sleeved on the first transmission wheels 131. By providing the first driving wheel 131, the driving mechanism 100 can be easily connected to the driving belt 210. Furthermore, each first driving wheel 131 is engaged with the driving belt 210 to transmit torque to one blocking mechanism 300, so that the two first driving wheels 131 enable the driving mechanism 100 to drive two blocking mechanisms 300 simultaneously.

Further, in this embodiment, each blocking mechanism 300 includes a fixing base 320 and a transmission shaft 330 rotatably disposed on the fixing base 320, two second transmission wheels 331 for sleeving the transmission belt 210 are disposed along the axial direction of the transmission shaft 330, and the blocking member 310 can move to extend into or move out of the transmission line along with the rotation of the transmission shaft 330.

The transmission shaft 330 is a generally elongated metal shaft member rotatably mounted on the fixing base 320 via a bearing so as to be rotatable about its own axis. The second driving wheel 331 has the same structure and function as the first driving wheel 131, and the driving belt 210 can be sleeved on the second driving wheel 331, so that the blocking mechanism 300 and the adjacent blocking mechanism 300 or driving mechanism 100 can realize transmission, so as to conveniently receive and transmit torque. Specifically, one of the second drive wheels 331 is engaged with the belt 210 such that the blocking mechanism 300 receives torque from either the drive mechanism 100 or the previous blocking mechanism 200, while the other second drive wheel 331 is engaged with the belt 210 such that torque is transmitted to the next blocking mechanism 200.

In addition, since the transmission shaft 330 has a long bar shape, the transmission of torque to the stopping member 310 through the transmission shaft 330 can separate the power end from the actuating end. In this way, it is more convenient for the stopper 310 to be disposed in a narrow space.

Referring to fig. 3, in the present embodiment, each blocking mechanism 300 further includes an elastic element 340, the elastic element 340 can generate an elastic restoring force, and the blocking mechanism 300 can be switched from the blocking state to the avoiding state by the elastic restoring force. Further, the transmission shaft 330 actuates the gear stop 310 to move in a cam-driven manner to switch the blocking mechanism 300 between the gear stop state and the avoidance state.

The transmission shaft 330 and the stop member 310 are in cam transmission. That is, the transmission shaft 330 and the stop gear 310 are not in a fixed connection, so that the drive mechanism 100 and the stop gear 310 can be decoupled. And the action of the elastic member 340 can prevent the stopping member 310 from accidentally extending into the transmission line to damage the material or the personnel.

Further, in the present embodiment, each blocking mechanism 300 further includes a swing shaft 350, a swing block 360, and an eccentric 370. Wherein:

the swing shaft 350 is rotatably disposed on the fixing base 320 and aligned with the extending direction of the transmission shaft 330, and the stopper 310 is fixed to one end of the swing shaft 350. Specifically, the swing shaft 350 may be configured and mounted in the same manner as the transmission shaft 330.

The swing block 360 is fixed to an end of the swing shaft 350 remote from the stopper 310. An eccentric 370 is fixed to one end of the transmission shaft 330, and the edge of the eccentric 370 abuts against the swing block 360. Specifically, one side of the swing block 360 may be formed with a groove-like structure that mates with an edge of the eccentric 370. The swing block 360 may be fixed to one end of the swing shaft 350 by a threaded fastener. The eccentric wheel 370 in this embodiment is fixed to the transmission shaft 330 through the turntable 332, the turntable 332 is coaxial with the transmission shaft 330, the eccentric wheel 370 is disc-shaped and fixed to one side of the turntable 332, and the center of the eccentric wheel is staggered from the center of the turntable 332. Thus, the eccentric wheel 370 can perform eccentric rotation with the rotation of the driving shaft 330.

The drive shaft 330 drives the stop 310 to move through the interaction of the eccentric 370 with the wobble block 360. Specifically, the eccentric wheel 370 serves as a driving member, and the swing block 360 serves as a driven member, which cooperate to form a cam transmission mechanism, so that the transmission shaft 330 can drive the stop member 310 to move in a cam transmission manner.

Specifically, in the embodiment, the elastic member 340 is a spring, one end of the spring is disposed on the fixing base 320, and the other end of the spring is disposed on the swinging block 360.

When the blocking mechanism 300 is switched to the shift stop state, the spring is stretched or compressed, thereby generating an elastic restoring force. Specifically, the fixed base 320 and the swing block 360 are both provided with spring supports (not shown), and two ends of the spring are respectively mounted on the spring supports of the fixed base 320 and the swing block 360.

In the present embodiment, each blocking mechanism 300 further includes a first proximity sensor 381, a second proximity sensor 382, and a sensor plate 390, and the sensor plate 390 is linked with the stop member 310. When the barrier mechanism 300 is in the stopped state and the retracted state, the sensor board 390 activates the first proximity sensor 381 and the second proximity sensor 382, respectively.

The sensing plate 390 may be fixed to the swing block 360 so as to be able to change positions as the swing block 360 swings. The fixed base 320 is further provided with a sensor holder 321, and the first proximity sensor 381 and the second proximity sensor 382 are both arranged on the sensor holder 321. Through the cooperation of the induction plate 390, the first proximity sensor 381, and the second proximity sensor 382, whether the stopping member 310 is moved in place can be detected in real time, thereby facilitating the automatic control of the stopping device 10.

In the stopping device 10, the driving mechanism 100 and at least two blocking mechanisms 300 are driven by the transmission mechanism 200, so the driving mechanism 100 and the blocking mechanisms 300 can be separately arranged, and the occupied space of a single blocking mechanism 300 is relatively small. Further, when the blocking mechanism 300 is in the retracted state, the stopper 310 is located outside the transmission line, and only when the blocking mechanism 300 is switched to the stopper state, the stopper 310 needs to be inserted into the transmission line. It can be seen that the stop arrangement 10 described above is suitable for use in confined spaces. Further, since the plurality of blocking mechanisms 300 can be driven by the same drive mechanism 100, the blocking mechanisms 300 can be synchronized with each other more easily.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
