Referring to fig. 1 and 2, the present application provides a carrying system, which includes a first rail 100, a carrying cart 200, and a closing assembly. The carrier cart 200 includes a door 250 and a cart body 210. The bin gate 250 has an open position and a closed position, and the bin gate 250 and the trolley body 210 enclose at the closed position to form an accommodating space. The carrier cart 200 is movable along the first rail 100. The closing assembly is disposed opposite to the first guide rail 100, and controls the door 250 to be switched from the open position to the closed position. Because the accommodating space can accommodate various goods, the applicability of the carrying trolley 200 is effectively improved. Meanwhile, the closing assembly automatically controls the bin gate 250 to be switched from the opening position to the closing position, the bin gate 250 does not need to be manually closed, and the sorting efficiency of the carrying system is improved.

Specifically, the cargo carried by the carrier cart 200 includes, but is not limited to, rod-shaped cargo, and the rod-shaped cargo is taken as an example for further description.

In the present embodiment, the carrier cart 200 includes a frame 220, a plurality of cart bodies 210, and a plurality of gates 250. One end of the bracket 220 is movably connected to the first rail 100 and can move along the first rail 100. The plurality of trolley bodies 210 correspond to the plurality of bin gates 250 one by one. The plurality of trolley bodies 210 are fixed on the bracket 220, and the plurality of trolley bodies 210 are arranged symmetrically. Specifically, the number of the cart bodies 210 may be 1, 2, 3, 4, 5, 6, or 8 or more, which is not limited herein. The carrier cart 200 is provided with a plurality of cart bodies 210, which is beneficial to improving the loading capacity of the carrier cart 200, and further increasing the sorting efficiency of the carrying system.

Further, referring to fig. 2 and 5, the carrying system further includes an auxiliary rail 300. The auxiliary guide rail 300 comprises a second guide rail 310, and a plurality of trolley bodies 210 are rotatably connected with guide wheels 230; the second guide rail 310 extends along the length direction of the first guide rail 100, and is disposed between two opposite trolley bodies 210 on the same support. Each of the guide wheels 230 is tangent to its corresponding second rail 310. The second guide rail 310 is arranged in the carrying system, so that the carrying trolley 200 is effectively prevented from shaking in the moving process. Meanwhile, a guide wheel 230 is provided on the cart body 210. During the movement of the carrier cart 200 along the first rail 100, the guide wheels 230 roll along the second rail 310, so that the movement of the carrier cart 200 is smoother.

Further, the auxiliary rail 300 further includes a third rail 320 and a fourth rail 330. The fourth guide rail 330 is disposed opposite to the third guide rail 320, and the second guide rail 310 is located between the third guide rail 320 and the fourth guide rail 330. The capsule assembly can be mounted on the second rail 310, the third rail 320, or the fourth rail 330, which is advantageous for reducing the load of the first rail 100.

Referring to fig. 2, the door 250 is configured to receive goods to be sorted. Specifically, the trolley body 210 is provided with a storage cavity (not identified in the figure), and a feeding hole 2101 and a discharging hole 2102 which are communicated with the storage cavity. The trolley body 210 is a hollow cylindrical member, which is beneficial for loading rod-shaped goods or cylindrical goods on the trolley body 210. Since conventional sorting equipment is limited by the width of the conveyor belt, it is generally suitable for sorting goods having a length not exceeding 400mm. And the carrying system that this application provided, because load goods the dolly body 210 is hollow cylindricality piece, be favorable to loading shaft-like goods or cylindricality piece goods, especially the shaft-like goods that goods length is more than 400mm, solved traditional letter sorting equipment and be difficult to the difficult technical problem of letter sorting shaft-like goods.

The connection manner of the door 250 and the trolley body 210 may be that the door 250 is directly connected with the trolley body 210, or that the door 250 is indirectly connected with the trolley body 210 through a connecting member, which is not limited herein.

In the embodiment of the present application, the door 250 is disposed at the discharge port 2102. The door 250 has a closed position and an open position. Fig. 2 shows a schematic configuration of the door 250 in a closed position, and fig. 1 shows a schematic configuration of the door 250 in an open position. When the door 250 is in the open position, the discharge passage is opened to allow the cargo to fall from the cart body 210. It will be appreciated by those skilled in the art that the discharge passage is the path that the goods travel when falling through the discharge port 2102 to the sort address.

However, in order to load the goods into the trolley body 210, the worker can still scan the labels on the goods by using the code scanning gun to assist the carrying system in sorting, so that the sorting efficiency is improved. In some embodiments of the present application, the carrier cart 200 further comprises a column 240. One end of the upright 240 close to the discharge port 2102 is fixedly connected with the trolley body 210, and the other end of the upright 240 extends in the direction far away from the feed port 2101 and is rotatably connected with the bin gate 250. In this way, the door 250 is spaced apart from the discharge port 2102 to form an open area, which forms a light-transmitting area. When the rod-shaped goods are inserted into the trolley body 210, the optical labels are located in the open area, so that the code scanning gun can still scan the optical labels on the goods after the goods are loaded into the trolley body 210.

In some embodiments of the present application, the carrier cart 200 includes an opening and closing lever 260. The opening and closing rod 260 is connected to the cart body 210 and the door 250, and controls the opening and closing of the door 250. When the opening and closing rod 260 controls the bin door 250 to be opened, namely, the bin door 250 is controlled to be switched from a closed position to an open position, the goods automatically fall from the trolley body 210, so that the goods are automatically sorted, the manual operation cost is reduced, and meanwhile, the phenomenon of goods accumulation is avoided. The opening and closing rod 260 controls the bin door 250 to be closed after the goods in the trolley body 210 are automatically sorted, that is, controls the bin door 250 to be switched from the open position to the closed position, so that when the next manual or automatic equipment loads the goods to the trolley body 210, the bin door 250 does not need to be closed first in the operation step and then the goods are loaded, the operation flow of the step is reduced, and the goods loading speed is increased, and the sorting efficiency of the carrying system is improved.

The opening and closing rod 260 may be a strip-shaped plate or a rod-shaped part. The opening and closing lever 260 includes a third end portion 261 and a fourth end portion 262 which are oppositely disposed. The third end 261 is rotatably connected to the cart body 210, and the fourth end 262 has a groove 2622. The door 250 has a first end 2501 and a second end 2502 opposite to each other, and the first end 2501 is rotatably connected to the pillar 240. The second end 2502 is at least partially disposed within the groove 2622 when the door 250 is in the closed position, and the second end 2502 is disengaged from the groove 2622 when the door 250 is in the open position. Of course, in other embodiments of the present application, the fourth end 262 may also be a plate-shaped portion with an L-shaped cross section, and those skilled in the art should understand that the L-shaped plate-shaped structure and the groove 2622 can have the same function, and can all support the bin gate 250, and will not be described herein again.

Further, a bottom surface of the second end portion 2502 is provided with a roller 253, and the roller 253 is used for triggering the door 250 to switch from an open position to a closed position (described in detail below).

Further, the opening and closing rod 260 further comprises a spring 263, and the spring 263 is used for resetting the opening and closing rod 260. Specifically, the spring 263 is a compression spring, one end of the compression spring is abutted to the trolley body 210, and the other end of the compression spring is abutted to one end of the opening and closing rod 260, which is far away from the fourth end 262. On one hand, when the compartment door 250 is in the closed position, the compression spring can apply a locking force to the opening and closing rod 260, so that the groove 2622 tightly holds the compartment door 250, and thus, it is ensured that the goods loaded in the cart body 210 cannot easily fall off during the moving process. On the other hand, when the door 250 is switched from the open position to the closed position, the compression spring can automatically reset the opening/closing rod 260 to lock the door 250 in the closed position. Of course, it should be understood by those skilled in the art that the spring 263 can also be a torsion spring, and the torsion spring is installed at the rotational connection position of the opening/closing rod 260 and the trolley body 210.

Further, an end surface 2621 of the fourth end 262 of the opening/closing lever 260 is an inclined surface. In the process of switching the door 250 from the open position to the closed position, the second end portion 2502 of the door 250 can slide along the end surface 2621, and at the same time, the edge of the second end portion 2502 continuously presses the end surface 2621 to rotate the opening/closing rod 260. For example, when the door 250 is in a horizontal position, the opening and closing lever 260 is reversely rotated and returned to an original state by the compression spring, so that the groove 2622 catches the door 250. Therefore, the end surface 2621 of the fourth end 262 of the opening/closing rod 260 is designed to be an inclined surface, which is beneficial to realize the automatic closing of the door 250. The closing of the bin gate 250 can be completed only by sliding the edge of the second end 2502 of the bin gate 250 along the end surface 2621, and the whole process does not need to be precisely adjusted, which is beneficial to improving the working efficiency of the carrying system.

Further, in order to reduce the resistance when the door 250 slides along the end surface 2621, the end surface of the second end portion 2502 may be designed to be an inclined surface that matches the inclination of the end surface 2621 of the fourth end portion 262.

Further, the carrying trolley 200 further comprises a positioning column 273. The positioning column 273 is fixedly connected to the outer surface of the trolley body 210 and arranged in parallel with the opening and closing rod 260. The positioning posts 273 are used to assist in opening and closing the door 250 (described in more detail below).

Referring to fig. 3, in other embodiments of the present application, the carrier cart 200 includes a bin gate control mechanism 270. The bin gate control mechanism 270 comprises a sliding block 271 and a connecting rod 272; the sliding block 271 is connected with the trolley body in a sliding manner; one end of the connecting rod 272 is rotatably connected to the bin gate 250, and the other end of the connecting rod 272 is rotatably connected to the sliding block 271; the sliding block 271 drives the connecting rod 272 to move so as to control the bin gate 250 to open or close.

Specifically, the bin gate 250 includes a first sub-bin gate 251 and a second sub-bin gate 252. The first sub-bin gate 251 has a fifth end 2511 and a sixth end 2512. The second sub-chamber gate 252 has a seventh end (not labeled) and an eighth end (not labeled). The fifth end 2511 is rotatably connected to the column 240, and the sixth end 2512 is rotatably connected to the link 272. The seventh end is rotatably connected to the upright 240, and the eighth end is rotatably connected to the connecting rod 272.

The link 272 includes a first sub-link 2721 and a second sub-link 2722. One end of the first sub-link 2721 is rotatably connected to the sixth end 2512 of the first sub-chamber door 251, and the other end of the first sub-link 2721 is rotatably connected to the slider 271. One end of the second sub-link 2722 is rotatably connected to the eighth end of the second sub-bin gate 252, and the other end of the second sub-link 2722 is rotatably connected to the slider 271.

The slider 271 is sleeved on the positioning column 273 and can slide up and down along the positioning column 273. The roller 253 is rotatably connected to the slider 271. The roller 253 is used to cause the slider 271 to slide upward (as described in more detail below). The outer surface of slider 271 is provided with a wedge 2711, and wedge 2711 is adapted to mate with groove 2622 (described in more detail below). The process that the sliding block 271 slides downwards along the positioning column 273, that is, the process that the first sub-chamber door 251 and the second sub-chamber door 252 open the discharging passage. Correspondingly, the sliding block 271 slides upwards along the positioning column 273, that is, the first sub-bin door 251 and the second sub-bin door 252 close the discharging passage. By adopting the technical scheme that the bin gate control mechanism 270 is matched with the first sub-bin gate 251 and the second sub-bin gate 252, the required rotating space when the bin gate 250 is switched from the closed position to the open position is favorably reduced, and the occupied space of a carrying system is favorably reduced.

In yet another embodiment of the present application, please refer to fig. 3 and 4. The carrier cart 200 includes a door control mechanism 270 and an opening and closing lever 260. For the specific structure and other features of the opening and closing rod 260 and the door control mechanism 270, please refer to the previous description, and the details are not repeated herein. During the process that the sliding block 271 slides upwards along the positioning column 273, the wedge 2711 slides along the end surface of the fourth end 262 of the opening and closing rod 260, until the first sub-compartment door 251 and the second sub-compartment door 252 are in the closed position, the wedge 2711 is located in the groove 2622. Since the groove 2622 of the opening and closing rod 260 can tightly clamp the wedge 2711, it is ensured that the sliding block 271 cannot easily slide during the moving process of the carrying trolley 200, and further ensured that the goods carried by the carrying trolley 200 cannot easily fall.

Referring to fig. 5 to 7, the closing module includes a trigger rail 400. The trigger rail 400 includes a first trigger rail 410 and a second trigger rail 420 that are symmetrically disposed. The horizontal heights of the first trigger rail 410 and the second trigger rail 420 gradually increase along the moving direction of the carrier cart 200. The first trigger rail 410 and the second trigger rail 420 have a guide surface 411, and specifically, the guide surface 411 is an end surface of the first trigger rail 410 or the second trigger rail 420. The guide surface 411 is used to facilitate the door 250 to switch from the open position to the closed position. In the moving direction of the carrier cart 200, the roller 253 moves along the guide surface 411 of the first trigger rail 410 and the second trigger rail 420 to rotate the door 250 from the open position to the closed position, for example, continuously rotate from the initial vertical state, until finally becoming the horizontal state to switch the door 250 from the open position to the closed position. The whole switching process is automatically completed along with the movement of the carrying trolley 200, manual intervention is not needed, the labor cost is saved, and the sorting efficiency of the carrying system is improved.

As an example, referring to fig. 1 and fig. 5, the guiding surface 411 is a curved surface, and specifically, a torsion angle of the guiding surface 411 is 90 degrees, that is, the guiding surface 411 has a first end and a second end that are oppositely disposed, and an included angle between a plane where the first end is located and a plane where the second end is located is 90 degrees. One end of the first trigger rail 410 is connected to one end of the second trigger rail 420, and has a herringbone shape. Specifically, after the door 250 opens the discharge channel, the door 250 is in an open position. As the carrier cart 200 continues to move forward to the first trigger rail 410 and/or the second trigger rail 420, the roller 253 comes into contact with the guide surface 411 of the first trigger rail 410 and/or the second trigger rail 420. As the carrier carriage 200 continues to move forward, the roller 253 rolls along the guide surface 411 of the first trigger rail 410 and/or the second trigger rail 420. The guide surfaces 411 of the first and second trigger rails 410 and 420 gradually press the door 250 to rotate, and during the process of switching the door 250 from the open position to the closed position, the second end portion 2502 of the door 250 can slide along the end surface 2621 of the opening/closing rod 260, and at the same time, the edge of the second end portion 2502 continuously presses the end surface 2621 to rotate the opening/closing rod 260. When the bin gate 250 is in a horizontal position, the opening and closing rod 260 reversely rotates and returns to an original state under the action of the spring 263, so that the bin gate 250 is clamped by the groove 2622. Therefore, the end surface 2621 of the fourth end 262 of the opening/closing rod 260 is designed to be an inclined surface, which is beneficial to make the closing process of the door 250 smoother.

Referring to fig. 6 and 7, as another example, the capsule assembly includes a guide plane; the first roller rolls along the guide plane, so that the sliding block is triggered to slide, and the connecting rod is driven to move to control the bin gate to be opened or closed. It should be noted that, when the guiding surface 411 is a plane, the guiding surface 411 is a guiding plane. The first trigger rail 410 is mounted on the third rail 320. The second trigger rail 420 is mounted on the fourth rail 330. The roller 253 mounted on the sliding block 271 moves along the guiding surface 411 of the first trigger rail 410 and/or the second trigger rail 420, so that the first trigger rail 410 and/or the second trigger rail 420 press the sliding block 271 to slide upwards, and in the process of sliding the sliding block 271 upwards, on one hand, the bin door 250 is driven by the connecting rod 272 to rotate from the open position to the closed position; on the other hand, the wedge 2711 slides along the end surface 2621, and at the same time, the wedge 2711 continuously presses the end surface 2621 to rotate the opening and closing lever 260. Until the door 250 is in the closed position, the opening and closing lever 260 is rotated reversely to the initial position by the spring 263, so that the groove 2622 catches the wedge 2711.

It should be understood by those skilled in the art that the roller 253 is disposed on the bottom surface of the second end portion 2502 of the door 250, or the roller 253 is disposed on the sliding block 271, and the roller 253 rolls along the trigger rail 400 to trigger the door 250 to switch from the open position to the closed position, so as to reduce the resistance of the door 250 when switching from the open position to the closed position, reduce the wear of the trigger rail 400 and the door 250, and prolong the service life of both. In other words, in other embodiments of the present application, the roller 253 is not necessary, and the door 250 or the slider 271 may be in direct contact with the guide surface 411. Along the moving direction of the carrying trolley 200, the guide surface 411 continuously presses the door 250 or the sliding block 271 so that the door 250 is switched from the open position to the closed position.

Referring to fig. 1 and 2, in other embodiments of the present application, a hook 221 is disposed at one end of the bracket 220.
