Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first", "second", and "third", etc. in the present invention are used for distinguishing different objects, and are not used for describing a specific order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions.

Referring to fig. 1, a carrying system according to an embodiment of the present disclosure includes a main rail 200, a carrying cart 100, and a compartment opening device 400; the cargo trolley 100 moves along the main rail 200 to transport the cargo thereon to a preset position; the cargo cart 100 includes a pallet 150; the pallet 150 has a closed position and an open position and is reciprocally switchable between the closed position and the open position; the pallet 150 bears the goods when in the closed position, and the pallet 150 releases the goods to the preset position when in the open position; the opening device 400 comprises a driving piece 410 and a trigger piece 420, wherein the trigger piece 420 has a trigger position and a non-trigger position; the driving member 410 controls the trigger 420 to switch back and forth between a trigger position and a non-trigger position, and the trigger 420 controls the supporting plate 150 to switch from the closed position to the open position when located at the trigger position.

Specifically, the cargo includes, but is not limited to, a rod-shaped member, and the cross-sectional shape of the rod-shaped member may be square, triangular, circular, or the like.

Further, referring to fig. 8, the loading system further includes a yard-scanning gun 600, and the yard-scanning gun 600 is communicatively connected to the warehouse-opening device 400. The goods are provided with labels; the code scanning gun 600 scans the label. The yard rifle 600 can be swept automatically to the goods to set up on the year thing system and sweep the sign indicating number to will acquire information feedback on the label is to the device 400 of opening a warehouse, is favorable to further improving year thing system's letter sorting efficiency.

In some embodiments of the present application, referring to fig. 1 and 2, the cart 100 includes a loading tube 110. The loading cylinder 110 is a hollow cylindrical member. Accordingly, the loading drum 110 has a loading port 114 and an unloading port 113 communicating with each other. Since the existing sorting apparatus is limited by its own structure, for example, by the width of a conveyor belt, it is difficult to sort goods having a length of 400mm or more. In the loading system provided by some embodiments of the present application, since the loading drum 110 for loading the goods is a hollow cylindrical structure, the goods (especially the rod-shaped pieces with a length of more than 400 mm) can be placed inside the loading drum 110 in a vertical or nearly vertical state, which solves the technical problem that the existing sorting equipment is difficult to be applied to the sorting operation of the rod-shaped pieces.

In order to place the rod-shaped elements inside the loading cartridges 110, the carrier system can still be automatically sorted by means of the yard scanning gun 600. As an example, the load trolley 100 further comprises a fixing post 130. One end of the fixing column 130 is fixedly connected to the loading cylinder 110, and the other end of the fixing column 130 is rotatably connected to the supporting plate 150. That is, the pallet 150 is spaced apart from the loading cylinder 110 and forms an open area therebetween. The presence of this open area widens the types of goods that can be loaded on the trolley 100, for example, not only rod-shaped items can be placed in the loading cylinder 110, but also letter or book goods can be placed on the pallet 150; on the other hand, after the rod-shaped member is inserted into the loading cylinder 110, the optical label is located in the open area between the pallet 150 and the unloading opening 113, which is beneficial for a code scanning gun to scan the optical label on the goods.

Further, the cargo cart 100 further includes a latching bar 140. The latch lever 140 includes a first end 141 and a second end 142 that are oppositely disposed. The second end 142 is provided with a groove 143, and the first end 141 is rotatably connected with the loading cylinder 110. The pallet 150 is disposed at the unloading port 113. The pallet 150 functions to support the goods located in the loading tube 110. The supporting plate 150 has a third end 151 and a fourth end 152 which are oppositely arranged, and the third end 151 is rotatably connected with the fixing column 130. The fourth end 152 is at least partially disposed within the recess 143 when the tray 150 is in the closed position, and the fourth end 152 is disengaged from the recess 143 when the tray 150 is in the open position. Of course, the second end 142 may also be designed to be L-shaped, and those skilled in the art should understand that the structure of the L-shape is the same as that of the groove 143, and all of them can play a role of supporting the supporting plate 150, and will not be described herein again.

Further, the cargo cart 100 further includes a first spring 146, and the first spring 146 is used for resetting the latching lever 140. The latch lever 140 is provided with a mounting lever (not shown) near the first end 141, and the length direction of the mounting lever is perpendicular to the length direction of the latch lever 140. Specifically, the first spring 146 is a compression spring. A part of the compression spring is sleeved on the mounting rod, and the mounting rod plays a role in limiting and fixing the compression spring (the first spring 146). One end of the compression spring (first spring 146) abuts against the loading cylinder 110, and the other end of the compression spring abuts against the first end portion 141 of the latch lever 140. The compression spring can apply a locking force to the locking lever 140 when the pallet 150 is in the closed position so that the recess 143 tightly holds the pallet 150, ensuring that the goods loaded in the loading drum 110 cannot easily fall off during the movement.

In other embodiments of the present application, the first spring 146 may also be a torsion spring, which is installed at the rotational connection between the latch lever 140 and the loading drum 110. Therefore, the structural design of the mounting rod can be omitted, and the structure of the latch rod 140 is simplified.

Referring to fig. 3 and 4, in other embodiments of the present application, the carrier cart includes a locking bar 140 and a slider-link mechanism 160, and the pallet 150 includes a first sub-pallet 153 and a second sub-pallet 154. The structure of the latch lever 140 is described above and will not be described herein. The slider-link mechanism 160 includes a slider 161, a link 162, and a guide post 163. The guiding column 163 is fixedly connected to the outer surface of the loading cylinder 110 and is disposed parallel to the locking lever 140. The first sub-pallet 153 and the second sub-pallet 154 have the same structure. The first sub-pallet 153 has a fifth end 1531 and a sixth end 1532. The fifth end portion 1531 is rotatably connected to the fixing post 130, and the sixth end portion 1532 is rotatably connected to the connecting rod 162. The second sub-pallet 154 has a seventh end (not shown) and an eighth end (not shown). The seventh end is rotatably connected to the fixing post 130, and the eighth end is rotatably connected to the connecting rod 162. The linkage includes a first sub-linkage 1621 and a second sub-linkage 1622. One end of the first sub-link 1621 is rotatably connected to the sixth end 1532 of the first sub-bracket 153, and the other end of the first sub-link 1621 is rotatably connected to the slider 161. One end of the second sub-link 1622 is rotatably connected to the eighth end of the second sub-bracket 154, and the other end of the second sub-link 1622 is rotatably connected to the slider 161. The sliding block 161 is sleeved on the guide post 163 and can slide up and down along the guide post 163. The process of sliding the slider 161 downward along the guide posts 163, that is, the process of switching the first sub-pallet 153 and the second sub-pallet 154 from the closed position to the open position. Accordingly, the slider 161 slides upward along the guide posts 163, that is, the first sub-pallet 153 and the second sub-pallet 154 are switched from the open position to the closed position. When the first sub-carrier 153 and the second sub-carrier 154 are in the closed position, at least a portion of the slider 161 is located in the recess 143. When the first sub-pallet 153 and the second sub-pallet 154 are in the open position, the slider 161 is disengaged from the groove 143. The slide-link mechanism 160 is adopted to cooperate with the first sub-supporting plate 153 and the second sub-supporting plate 154, which is beneficial to reducing the rotation space required when the supporting plate 150 is switched from the closed position to the open position, and is further beneficial to reducing the space occupation of the carrying system.

When the loading drum 110 moves in the cargo conveying direction, the latching lever 140 rotates to separate the slider from the recess 143 (described in detail below). The slider 161 moves downward along the guide posts 163 by gravity, thereby moving the first sub-pallet 153 and the second sub-pallet 154 from the closed position to the open position. The goods then fall from the loading drum 110 into the corresponding predetermined position.

Referring to fig. 1 and 2, in some embodiments of the present application, the cargo cart 100 includes a frame 120, a plurality of loading cylinders 110, and a plurality of pallets 150. One end of the fixing frame 120 is movably connected to the main rail 200 and can move along the main rail 200. The plurality of loading cylinders 110 correspond to the plurality of pallets 150 one by one. A plurality of the loading cartridges 110 are fixed to the fixing frame 120. The plurality of the loading cylinders includes a first sub-loading cylinder 111 and a second sub-loading cylinder 112, and the first sub-loading cylinder 111 and the second sub-loading cylinder 112 are symmetrically arranged with respect to each other. Of course, this is merely an illustration of the number of loading cartridges 110, and the number of loading cartridges 110 is not limited to 2, and the number of loading cartridges 110 may be 4, 6, or 8 or more in some embodiments. The loading drums are arranged in the cargo carrying trolley 100, so that the loading capacity of the cargo carrying trolley 100 is improved, and the sorting efficiency of the loading system is improved.

Further, referring to fig. 1, fig. 2 and fig. 5, the carrying system further includes a sub-track 300; the auxiliary rail 300 includes a first sub-rail 310, and a plurality of guide wheels 131 are rotatably connected to each of the loading cylinders 110; the first sub-rail 310 is disposed between two rows of the loading cartridges 110, and the guide wheels 131 are tangent to the first sub-rail 310. The additional arrangement of the first sub-rail 310 in the loading system effectively prevents the cargo vehicle 100 from shaking during the movement of the loading canister 110 or when the opening device 400 triggers the pallet 150 to switch from the closed position to the open position. Meanwhile, the guide wheels 131 are arranged in the two rows of symmetrical loading cylinders 110, and the guide wheels 131 roll along the first sub-rail 310 during the movement of the cargo trolley 100, so that on one hand, the resistance applied to the movement of the cargo trolley 100 is smaller, and on the other hand, the cargo trolley 100 is prevented from shaking when the pallet 150 is switched from the closed position to the open position.

Further, referring to fig. 1 and 8, the sub-track 300 further includes a second sub-track 320 and a third sub-track 330. The third sub-track 330 is arranged opposite to the second sub-track 320, and the first sub-track 310 is located between the second sub-track 320 and the third sub-track 330. The opening device 400 can also be installed on the second sub-rail 320 or the third sub-rail 330, which is beneficial to reducing the load of the main rail 200.

Referring to fig. 10, in some embodiments of the present application, the carrier system further includes a first chain (not shown) and a chain drive 500; the first chain is positioned in the main track 200, and the cargo trolley 100 is suspended on the first chain; the chain drive 500 drives the first chain in rotation. Specifically, the cargo cart 100 is provided with a hook (not shown). The rotating speed of the first chain is adjustable. When the number of the goods needing to be sorted by the carrying system is more, the sorting efficiency of the carrying system can be improved by improving the rotating speed of the first chain under the condition of not changing the number of the carrying trolleys 100 in the carrying system; on the other hand, the number of the cargo carrying trolleys 100 in the cargo carrying system can be adjusted according to actual conditions in a suspension mode, so that the purpose of adjusting the sorting speed of the cargo carrying system is achieved. For example, when the cargo carrying system needs to sort a large number of cargos, the sorting efficiency of the cargo carrying system can be improved by increasing the number of the cargo carrying trolleys 100 without changing the speed of the first chain.

The chain drive 500 includes a dial tooth; the toggle teeth 522 cooperate with the first chain to drive the first chain to rotate. Specifically, the chain drive 500 further includes a power source and a speed reducer. The power source is matched with the speed reducing device to enable the stirring teeth 522 to rotate, and then the first chain is driven to rotate. As an example, the motor 560 serves as a power source of the chain drive 500. The reduction unit includes a primary reduction unit 530, a secondary reduction unit 540, and a tertiary reduction unit 550. The power output by the motor 560 passes through the first-stage reduction gear 530, the second-stage reduction gear 540 and the third-stage reduction gear 550 in sequence. The primary reduction gear 530 is belt driven, which is beneficial to improving the overload prevention capability of the chain drive 500. The second reduction gear 540 and the third reduction gear 550 adopt a sprocket-chain transmission mode.

Wherein, the third-stage reduction gear 550 drives the second chain 510 to rotate. The second chain 510 is provided with a toggle 520. Specifically, the toggle member 520 includes a fixed seat 521 and a toggle tooth 522. The toggle teeth 522 are similar to the sprocket tooth profile. The toggle teeth 522 are installed on the fixed seat 521, the fixed seat 521 is installed on the second chain 510, and the second chain 510 drives the first chain to rotate through the toggle component 520. The motor 560 drives the second chain 510 to rotate through the first reduction gear 530 and the second reduction gear 540, and further drives the first chain to rotate through the dialing teeth 522. Because the second chain 510 can be provided with a plurality of the poking teeth 522, compared with the conventional technical scheme that the chain wheel is adopted to drive the first chain to rotate, in which only a plurality of teeth on the chain wheel drive the chain at the same time, and the transmission power is low, the number of the poking teeth 522 capable of driving the first chain to rotate at the same time in the technical scheme is more, and thus the transmission power is higher.

Please refer to fig. 5 to 9. In the embodiment of the present application, the opening device 400 is used to control the opening of the tray 150, that is, to control the tray 150 to be switched from the closed position to the open position.

The cargo cart 100 includes a latch lever 140, and the trigger in the trigger position causes the latch lever 140 to rotate, thereby triggering the transfer of the pallet 150 from the closed position to the open position. Since the detailed description of the specific structure, the position relationship, etc. of the latch lever 140 has been given above, the detailed description is omitted here. The drive member includes a first rod 412. The first lever 412 is connected to the trigger; specifically, the trigger 420 includes a first sub-plate 421. The first rod 412 can extend and retract along a preset direction to drive the trigger to switch between a trigger position and a non-trigger position. When the trigger is in the trigger position, the locking lever 140 is rotated to trigger the supporting plate 150 to be switched from the closed position to the open position. The driving member 410 drives the first sub-board 421 to move to the triggering position when the goods need to be sorted to the corresponding preset position. The latch lever 140 is shifted from the closed position to the open position by the pressing of the first sub-board 421.

Referring to fig. 8 and 9, in an embodiment of the present application, the first sub-board 421 is fixedly connected to the first rod 412. As an example, when the cargo carried by the cargo cart 100 needs to fall into the corresponding predetermined position, the electromagnet 411 is powered on, and the first rod 412 pushes the first sub-board 421 to move to the triggering position and pushes the latch lever 140 to rotate so as to disengage the fourth end portion 152 from the recess 143. When the cargo falls into the corresponding preset position from the cargo trolley 100, the electromagnet 411 is powered off, and the first rod 412 drives the first sub-board 421 to move from the triggering position to the non-triggering position.

Specifically, the opening device 400 further includes a connecting member 440 and a bracket 430. The drive member 410 further comprises an electromagnet 411. The link 440 includes a first link 443 and a sliding shaft 444; the bracket 430 includes a positioning part 431. The electromagnet 411 drives the first rod 412 to move along a preset direction N, so as to drive the first sub-board 421 to move from a non-trigger position to a trigger position. Specifically, the first connecting member 443 is a rectangular parallelepiped bar-shaped member, a first through hole (not shown) is formed in the middle of the first connecting member 443, and the first rod 412 passes through the through hole and is fixedly connected to the first connecting member 443. The positioning portion 431 is provided with a second through hole (not labeled in the figure). The sliding shaft 444 is inserted into the second through hole and is slidable in the second through hole. One end of the sliding shaft 444 is fixedly connected to the first connector 443, and the other end of the sliding shaft 444 is fixedly connected to the first sub-board 421. When the electromagnet 411 is powered on, the first rod 412 moves along the N direction, and the first rod 412 drives the first sub-board 421 to move from the non-trigger position to the trigger position through the connecting member 440. When the electromagnet 411 is powered off, the first rod 412 moves in a direction opposite to the N direction, and the first rod 412 drives the first sub-board 421 to move from the activated position to the deactivated position through the connecting member 440.

When the first sub-board 421 is at the triggering position, the plane of the first sub-board 421 intersects with the conveying direction of the goods. When the cargo cart 100 passes the first subplate 421, the first subplate 421 continuously presses the latch bar 140, and the latch bar 140 rotates to switch the pallet 150 from the closed position to the open position. When the electromagnet 411 is kept in the energized state, the first rod 412 is contracted in the N direction, and the first sub-board 421 is located at the trigger position. When the cargo loaded on the cargo carrying trolley 100 needs to fall into the corresponding preset position, and the cargo carrying trolley 100 moves close to the first sub-board 421, the first sub-board 421 will abut against the lock catch bar 140. As the cargo cart 100 continues to move forward, the first subplate 421 will continue to compress the latching bar 140 and the first spring 146 will continue to be compressed, thereby rotating the latching bar 140. As the latch lever 140 is rotated to a certain angle, the fourth end 152 is separated from the recess 143, and the pallet 150 is rotated downward by its own weight, so that the pallet 150 is opened, and the cargo is then dropped from the cargo cart 100 into a corresponding predetermined position. When the first sub-board 421 is at the triggering position, the plane where the first sub-board 421 is located intersects with the conveying direction of the goods, so that the cargo trolley 100 can finish unloading in the moving process, and does not need to stay at the preset position, thereby effectively improving the sorting efficiency of the sorting system.

Further, if the load on the next adjacent cart 100 is not to be sorted into the predetermined position, the electromagnet 411 is turned off, the first rod 412 moves in the direction opposite to the predetermined direction (N direction), and the first sub-board 421 moves away from the triggering position to the non-triggering position. Therefore, the latching lever 140 of the subsequent cargo cart 100 is not pressed to rotate to separate the fourth end 152 from the recess 143, and the cargo does not fall out of the cargo cart 100.

In another embodiment of the present application, please refer to fig. 5-7. The driver 410 further comprises a second spring 414. The electromagnet 411 drives the first rod 412 to extend and retract along a preset direction F; the second spring 414 is sleeved on the first rod 412; the second spring 414 provides power for the first sub-plate 421 to switch between the triggering position and the non-triggering position when the electromagnet 411 stops working. The first lever 412 is movably connected to the trigger 420. When the first rod 412 extends and retracts along a preset direction, the connecting member 440 drives the trigger member 420 to rotate, so that the trigger member 420 is switched between a trigger position and a non-trigger position.

When the first rod 412 extends and retracts along a preset direction, the first sub-board 421 is driven to rotate by the connecting member 440, so that the first sub-board 421 is switched between a triggering position and a non-triggering position. The first sub-plate 421 is shown in the activated position in fig. 5, and the first sub-plate 421 is shown in the non-activated position in fig. 6. When the first sub-board 421 is located at the triggering position, one end surface of the first sub-board 421 inclines towards the moving direction of the goods to form a guiding inclined surface. The driving member 410 is mounted on the bracket 430. The driving member 410 drives the first sub-board 421 to move to the triggering position when the goods are sorted to the corresponding predetermined positions.

Specifically, the connection member 440 includes a second post 441 and a second sub-plate 442. The first sub-board 421 is rotatably coupled to the bracket 430. The second sub-board 442 is connected to the first sub-board 421. The second sub-board 442 has a V-shape. The bracket 430 may be installed on the main rail 200, may also be installed on the ground, or may be installed on the second sub-rail 320 or the third sub-rail 330, which is not particularly limited herein. The guide slope is an end surface of the first sub-board 421. The second rod 441 is connected to the first rod 412, and a central axis of the second rod 441 is perpendicular to a central axis of the first rod 412. The second spring 414 is a compression spring. The compression spring is sleeved on the first rod 412. The electromagnet 411 controls the first rod 412 to move in the direction F.

When the cargo loaded on the cargo cart 100 needs to fall into the corresponding preset position, the electromagnet 411 controls the first rod 412 to move along the direction F, the compression spring (the second spring 414) is compressed, and the second sub-board 442 rotates clockwise and further drives the first sub-board 421 to move to the triggering position. Then, when the loading cylinder 110 continues to move close to the opening device 400, the first sub-plate 421 will abut against the locking rod 140, i.e. the guiding inclined surface will abut against the locking rod 140. As the loading drum 110 continues to move forward, the guide slope continuously presses the latching lever 140 and the first spring 146 is continuously compressed, thereby rotating the latching lever 140. As the locking lever 140 is rotated to a certain angle, the fourth end portion 152 (or the slider 161) is separated from the recess 143, and the pallet 150 is rotated downward by gravity, so that the goods fall from the loading drum 110 into a corresponding predetermined position.

Further, in order to make the driving member 410 more responsive, the second sub-plate 442 abuts against the second rod 441, i.e. the surface of the second sub-plate 442 is tangential to the surface of the second rod 441. Thus, when the first bar 412 moves in the direction F, the first sub-plate 421 rotates synchronously.

Further, in order to keep the second rod 441 tangent to the second sub-plate 442 at all times so as to enable the opening device 400 to work normally, the driving member 410 is rotatably connected to the bracket 430. The driving member 410 is inclined downward by a certain angle, and the driving member 410 can keep the second rod 441 tangent to the second sub-plate 442 under the action of gravity.

Further, in order to make the process of moving the second rod 441 along the end surface of the second sub-plate 442 smoother, the second rod 441 has a cylindrical short axis and is rotatably connected to the first rod 412. That is, a through hole is formed at one end of the first rod 412, and the second rod 441 is inserted into the through hole and can rotate therein. Therefore, when the first rod 412 moves along the direction F, the second rod 441 rolls on the end surface of the second sub-plate 442, so that the rotation process of the second sub-plate 442 is smoother, and the abrasion of the contact surface between the two is reduced.

Further, referring to fig. 6, if the goods loaded in the next adjacent loading drum 110 are not required to be sorted into the predetermined position, the electromagnet 411 stops working, the first rod 412 moves in the opposite direction of the direction F under the action of the compression spring, and the first sub-plate 421 moves away from the triggering position to the non-triggering position. Therefore, the latch lever 140 in the subsequent loading bucket 110 is not rotated by being pressed to separate the fourth end 152 (or the slider 161) from the recess 143, and the cargo does not fall from the loading bucket 110.

Further, each preset position corresponds to one bin opening device 400. When the cargo trolley 100 passing through the preset position needs to unload the loaded cargo into the preset position, the opening device 400 corresponding to the preset position works to move the first sub-plate 421 to the triggering position, so that the cargo system can automatically complete the unloading work without manual unloading, thereby not only saving the labor cost, but also improving the sorting efficiency.

Based on the technical information disclosed in the present application, those skilled in the art should know that in this alternative, the driving member 410 can be directly replaced by a telescopic cylinder or a hydraulic cylinder.

In some embodiments of the present application, referring to fig. 1 and 2, in order to make the guiding slope trigger the latching bar 140 to rotate so as to make the process of separating the fourth end 152 (or the sliding block 161) from the recess 143 smoother, the cargo cart 100 further includes a roller 145. The roller 145 is rotatably coupled to the first end 141 of the latch lever 140. The roller 145 can roll along the guiding slope to trigger the latch lever 140 to rotate so as to separate the fourth end 152 (or the slider 161) from the groove 143.

In a second aspect, the present application provides a sorting method, comprising: the cargo is thrown into the cargo carrying trolley 100; the cargo trolley 100 comprises a supporting plate 150, the supporting plate 150 has a closed position and an open position and can be switched between the closed position and the open position in a reciprocating mode, the supporting plate 150 bears the cargo when in the closed position, and the supporting plate 150 releases the cargo to a preset position when in the open position; the loading trolley 100 is driven to move to a preset position along the main rail. The bin opening device triggers the supporting plate 150 to be switched from the closed position to the open position when the cargo trolley 100 is in a preset position; wherein the opening device comprises a driving piece 410 and a trigger piece 420, and the trigger piece 420 has a trigger position and a non-trigger position; the driving member 410 controls the trigger 420 to switch back and forth between the trigger position and the non-trigger position, and the trigger 420 controls the supporting plate 150 to switch from the closed position to the open position when located at the trigger position. When the cargo is transported to the preset position, the driving member 410 drives the trigger member 420 to switch from the non-trigger position to the trigger position, and when the cargo truck 100 passes through the trigger member 420 in the trigger position, the trigger member 420 in the trigger position triggers the pallet 150 to switch from the closed position to the open position. It should be noted that in the embodiments of the present application, the cargo cart and the opening device have been specifically described in the foregoing, and are not repeated here.
