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 obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection 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 and 2, the present application provides a cargo carrying device 100 including a support plate 150, a cartridge 110, and an opening and closing assembly. The supporting plate 150 and the material barrel 110 enclose to form a containing space for containing goods. Fig. 1 is a schematic view of the support plate 150 in the closed position, and fig. 3 and 5 are schematic views of the support plate 150 in the open position. The support plate 150 carries the cargo when in the closed position. When the support plate 150 is in the open position, the goods loaded thereon are sorted to the corresponding sorting addresses. The opening and closing assembly controls the support plate 150 to switch back and forth between the open and closed positions.

The cargo device 100 has better applicability since the accommodation space is suitable for loading most types of cargo. When the goods are sorted, the goods are only loaded into the accommodating space, and then the opening and closing assembly controls the supporting plate 150 to be switched from the closed position to the open position, and then the goods are immediately sorted to the corresponding sorting addresses. So recycling has realized the automatic letter sorting of goods for letter sorting efficiency has obtained effective improvement.

Specifically, the cargo includes, but is not limited to, a rod, and the cross-sectional shape of the rod may be square, triangular, circular, and the like, and is not limited herein. The rod-like member will be further described below as an example.

It should be mentioned that the sorting address refers to a temporary storage location corresponding to the goods. Referring to fig. 5, in order to actually sort the goods, since different goods have different dispatch addresses, a plurality of sorting chute assemblies 300 for temporarily collecting the goods are arranged along the moving direction of the loading device 100 to collect the goods corresponding to the same dispatch address. Specifically, the sorting chute assembly 300 includes a sorting chute 310 and a collection bin 320. For example, if the delivery is required to different cities for a courier, the label on each item describes the destination information of the item, such as that item 1 is required to be dispatched to city a, item 2 is dispatched to city B, and so on. The entrance of the sorting chute 310 is defined as a sorting gate for sending goods to city a, and the sorting gate is a sorting gate corresponding to the goods to be delivered to city a; at this time, the position where the sorting chute 310 is located corresponds to a sorting address. Of course, different sorting chutes 310 and collection boxes 320 may be defined to collect the goods corresponding to the same weight range or length range, and will not be described herein.

In the present embodiment, the support plate 150 is configured to carry goods to be sorted. Referring to fig. 1 and 5, in particular, the loading device 100 is a carrying case. The loading unit 100 includes a support plate 150 and a cartridge 110. The cartridge 110 is provided with a receiving space (not shown), and a loading port 1101 and an unloading port 1102 communicating with the receiving space. The cartridge 110 is a hollow cylindrical member to facilitate loading of the cartridge 110 with rod or cylindrical goods. 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. In the loading device 100 provided by the present application, since the material cylinder 110 for loading the goods is a hollow cylindrical member, it is beneficial to load rod-shaped or cylindrical goods, especially rod-shaped goods with a length of more than 400mm, and the technical problem that the traditional loading device is difficult to load and sort the rod-shaped goods is solved. Further, the shape of the loading port 1101 of the cartridge 110 may be designed to be a horn shape, so as to increase the area of the loading port 1101, thereby facilitating the speed of loading the goods into the cartridge 110 and improving the efficiency of loading the goods. It should be noted that the size and shape of the cartridge 110 may be set according to the size and shape of the goods, and is not limited herein.

In the present embodiment, the support plate 150 is disposed at the unloading port 1102. Further, in order to facilitate the cargo carrying device 100 of the embodiment of the present application to sort the cargo, the cargo may be labeled. In particular, the label may be an optical label such as a bar code or a two-dimensional code. The optical label is sprayed or stuck on the surface of the goods. Illustratively, the optical tag is affixed to one end of the cargo. When the goods are loaded on the support plate 150, the label to which the goods are attached is close to the unloading opening 1102. In this way, before the cargo carrying device 100 sorts the cargo carried thereon to the corresponding sorting address, the worker may scan the optical label with a code scanning gun in a hand or with an automatic code scanning device to perform the sorting operation on the cargo.

In the embodiment of the present application, the supporting plate 150 is movably connected to the cartridge 110 to open or close the discharging passage so as to perform a sorting operation of the goods. It should be noted that the movable connection between the supporting plate 150 and the cartridge 110 may be a sliding connection or a rotating connection. The support plate 150 may be directly connected to the cartridge 110, or the support plate 150 may be indirectly connected to the cartridge 110 through a connecting member, which is not limited herein. It will be understood by those skilled in the art that the emptying channel, i.e. the path along which goods fall through the discharge opening 1102 to the sorting address.

In some embodiments of the present application, the support plate 150 is directly rotatably coupled to the cartridge 110 to open or close the discharge opening 1102.

However, in order to enable the barcode scanner to scan the optical label on the goods after the goods are loaded into the cartridge 110, the cartridge 110 is provided with a light-transmitting area at a position corresponding to the label. Specifically, the cartridge 110 is at least partially made of a light-transmitting material, which may be a transparent resin or glass, and is not limited herein. The light-transmitting material forms the light-transmitting area on the cartridge 110, for example, the cartridge 110 is made of a light-transmitting material, so that the entire accommodating space becomes the light-transmitting area. For another example, one end of the cartridge 110 close to the support plate 150 is made of a light-transmitting material, so that the area of the accommodating space close to the support plate 150 becomes a light-transmitting area.

In other embodiments of the present application, the cargo conveyance 100 further includes a post 130. With continued reference to fig. 1 or fig. 2, one end of the support post 130 near the discharge opening 1102 is fixedly connected to the cartridge 110, and the other end of the support post 130 extends in the direction of the loading opening 1101 and the discharge opening 1102 and is rotatably connected to the support plate 150. In this manner, the support plate 150 is spaced apart from the discharge opening 1102 to form an open area, which forms a light-transmitting area. When the rod cargo is inserted into the cartridge 110, the optical label is located in the open area between the support plate 150 and the unloading opening 1102, so that the code scanning gun can still scan the optical label on the cargo after the cargo is loaded into the cartridge 110. A limiting wheel 131 is rotatably connected to one end of the supporting column 130 near the supporting plate 150, and the limiting wheel 131 cooperates with an auxiliary guide rail (not shown) to prevent the cargo carrying device 100 from shaking during moving. Of course, in this embodiment, the connection manner of the end of the support column 130 far away from the unloading opening 1102 and the support plate 150 can also be a sliding connection, and is not limited herein.

In some embodiments of the present application, the cargo conveyance 100 further includes an opening and closing assembly. The opening and closing assembly is connected to the cartridge 110 and the support plate 150, and controls the opening or closing of the support plate 150. When the opening and closing assembly controls the supporting plate 150 to be opened, that is, the supporting plate 150 is controlled to be switched from the closed position to the open position, the goods can automatically fall into the corresponding sorting addresses from the charging barrel 110, so that the automatic sorting of the goods is realized, the manual operation cost is reduced, and the phenomenon of goods accumulation is avoided. After the goods in the material cylinder 110 are automatically sorted, the opening and closing assembly controls the supporting plate 150 to be closed, that is, the supporting plate 150 is controlled to be switched from the opening position to the closing position, so that when the next time of loading the goods into the material cylinder 110 by manual or automatic equipment, the supporting plate 150 does not need to be closed first in the operation step to reload the goods, the operation flow of the step is reduced, and the improvement of the goods loading speed and the sorting efficiency of the sorting system are facilitated.

As an example, as shown in fig. 1 and 2, the opening and closing assembly includes a locking bar 140. The locking bar 140 may be a strip-shaped plate or a rod-shaped member. The lock bar 140 includes a first end 1401 and a second end 1402 opposite to each other. The first end 1401 is provided with a recess 141 and the second end 1402 is rotatably connected to the cartridge 110. The second end 1402 is rotatably connected with the opening wheel 143, and the fourth end 1502 is disengaged from the groove 141 by pressing the opening wheel 143 to move the locking bar 140. The support plate 150 has a third end 1501 and a fourth end 1502 opposite to each other, and the third end 1501 is rotatably connected to the support column 130. The fourth end 1502 is at least partially disposed within the recess 141 when the support plate 150 is in the closed position, and the fourth end 1502 is disengaged from the recess 141 when the support plate 150 is in the open position. Of course, the first end 1401 may 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 141, and can support the supporting plate 150, which is not described herein again. The bottom surface of the fourth end 1502 of the support plate 150 is rotatably connected with a closing wheel 153, and the support plate 150 is switched from the open position to the closed position by pressing the closing wheel 153.

Further, the opening and closing assembly further includes a first elastic member 144, and the first elastic member 144 is used for restoring the locking bar 140. The locking bar 140 is provided with a pressing rod 142 near the second end 1402 thereof, and the pressing rod 142 is perpendicular to the length direction of the locking bar 140. Of course, the pressing rod 142 may also be fixedly disposed at the outer surface of the barrel 110; alternatively, the locking rod 140 is provided with a pressing rod 142 having a central axis coincident with the outer surface of the barrel 110 near the second end 1402 thereof, which is not limited herein.

Specifically, the first elastic member 144 is a compression spring. One part of the compression spring is sleeved on the compression rod 142, and the compression rod 142 can limit and fix the compression spring to a certain extent. One end of the compression spring abuts the cartridge 110 and the other end of the compression spring abuts the end of the lock lever 140 remote from the first end 1401. On one hand, the compression spring can apply a locking force to the locking bar 140 when the support plate 150 is in the closed position so that the groove 141 tightly catches the support plate 150, ensuring that the goods loaded in the cartridge 110 cannot easily fall off during the movement. On the other hand, during the process of transferring the support plate 150 from the open position to the closed position, the compression spring enables the locking bar 140 to automatically return to lock the support plate 150 in the closed position.

Further, the end 1403 of the first end 1401 of the locking bar 140 is an inclined surface. During the switching of the support plate 150 from the open position to the closed position, the fourth end 1502 of the support plate 150 can slide along the end 1403, and simultaneously the edge of the fourth end 1502 continuously presses the end 1403 to rotate the lock lever 140. When the support plate 150 is in the horizontal position, the locking rod 140 is reversely rotated and restored to the original state under the action of the compression spring, so that the groove 141 catches the support plate 150. Therefore, the end 1403 of the first end of the locking bar 140 is designed to be inclined to facilitate the closing process of the support plate 150. The edge of the fourth end 1502 of the support plate 150 only needs to be operated to slide along the inclined plane to complete the closing of the support plate 150, the whole process does not need to be accurately adjusted, and the improvement of the working efficiency of the sorting system is facilitated.

Further, in order to make the sliding process of the support plate 150 along the inclined surface smoother, the end surface of the fourth end portion may be designed to be inclined to match the inclination of the end surface 1403 of the first end portion. Alternatively, a guide wheel may be mounted at the fourth end portion 1502. The guide wheel rolls along the end surface 1403 of the first end of the locking bar 140, so that the support plate 150 is smoothly converted from the open position to the closed position.

In other embodiments of the present application, the first elastic member 144 may also be a torsion spring, and the torsion spring is installed at the rotational connection between the locking lever 140 and the cartridge 110. Thus, the structural design of the pressing rod 142 can be omitted, and the structure of the locking rod 140 is simplified.

In other embodiments of the present application, the opening and closing assembly may also be a motor assembly. Specifically, the motor assembly is mounted at the rotational connection between the support column 130 and the support plate 150. The motor assembly is used for replacing the locking rod 140 to control the opening or closing of the supporting plate 150, so that the locking rod 140 of the loading device 100 can be omitted, the number of parts of the loading device 100 is reduced, and the working reliability of the loading device is improved.

It should be mentioned that, in other embodiments of the present application, please refer to fig. 3 and 4. The opening and closing assembly may further include a slider-link mechanism 200.

Specifically, the opening and closing assembly includes a locking rod 140, a positioning column 230 and a slider-link mechanism 200, and the supporting plate 150 includes a first sub-supporting plate 151 and a second sub-supporting plate 152. The positioning post 230 is fixedly connected to the outer surface of the barrel 110 and arranged in parallel with the locking bar 140. The first and second sub-bearing plates 151 and 152 each have a fifth end and a sixth end. The fifth end is rotatably connected to the strut 130, and the sixth end is rotatably connected to the link. The link 220 includes a first link 221 and a second link 222. One end of the first link rod 221 is rotatably connected to the sixth end of the first sub-supporting plate 150, and the other end of the first link rod 221 is rotatably connected to the slider 210. One end of the second link 222 is rotatably connected to the sixth end of the second sub-supporting plate 152, and the other end of the second link 222 is rotatably connected to the slider 210. The sliding block 210 is sleeved on the positioning column 230 and can slide up and down along the positioning column 230. The closing wheel 153 is rotatably connected to the sliding block 210. The process of sliding the sliding block 210 downwards along the positioning pillar 230, that is, the process of opening the discharge channel by the first sub-supporting plate 151 and the second sub-supporting plate 152. Accordingly, the process of sliding the sliding block 210 upwards along the positioning column 230, that is, the process of closing the discharge passage by the first sub-supporting plate 151 and the second sub-supporting plate 152. When the first sub-supporting plate 151 and the second sub-supporting plate 152 are in the closed position, the sliding block 210 is at least partially located in the groove 141. The slider-link mechanism 200 is used in conjunction with the first sub-supporting plate 151 and the second sub-supporting plate 152, which is beneficial to reduce the rotation space required when the supporting plate 150 is switched from the closed position to the open position, and further beneficial to reduce the space occupied by the cargo carrying device when the cargo carrying device sorts the cargo.

When the cartridge 110 moves in the goods transferring direction, the locking lever 140 rotates to separate the slider 210 from the groove 141. The sliding block 210 moves downwards along the positioning column 230 under the action of gravity, so as to drive the first sub-supporting plate 151 and the second sub-supporting plate 152 to be switched from the closed position to the open position, the discharging channel is opened, and the goods immediately drop from the charging barrel 110 into the corresponding sorting address.

With continued reference to fig. 1 and 2, in some embodiments of the present application, the load carrying device 100 includes a cushioning element disposed on the support plate 150. Specifically, the buffer assembly includes a buffer plate 154 and a second elastic member 155. The buffer plate 154 is spaced apart from the support plate 150, and the second elastic member 155 connects the buffer plate 154 and the support plate 150. In one embodiment of the present application, the second elastic member 155 is a compression spring. The compression springs are disposed at four corners of the buffer plate 154, respectively. In other embodiments of the present application, the second elastic member 155 may also be a disc spring or a leaf spring or a rubber pad. Of course, in other embodiments of the present application, the cushioning component may also be a rubber coating that is sprayed onto the surface of the support plate 150. A cushioning assembly is provided in the cargo carrying device 100 to facilitate cushioning of the cargo from impacting the support plate 150 when the cargo is loaded.

Referring to fig. 1 and 5, in another aspect, the present disclosure provides a sorting system including the loading device 100 and a traction guide 400. In some embodiments of the present application, the loading unit 100 includes a frame 120, a plurality of the cartridges 110, and a plurality of the support plates 150. One end of the frame body 120 is provided with a hook 121. The loading device is movably connected with the traction guide rail 400 through the hook 121 and can move along the traction guide rail 400. The plurality of cartridges 110 corresponds to the plurality of support plates 150 one by one. A plurality of the cartridges 110 are fixed to an end of the frame body 120 away from the traction guide 400. The plurality of cartridges 110 includes a first sub-cartridge 111 and a second sub-cartridge 112, and the first sub-cartridge 111 and the second sub-cartridge 112 are symmetrically arranged with respect to each other. Of course, the number of cartridges 110 is merely illustrative and is not limited to 2, and in some embodiments, the number of cartridges 110 may be 4, 6, or 8 or more. The provision of a plurality of cartridges 110 in the load carrying apparatus 100 facilitates an increased loading capacity of the load carrying apparatus 100 and thus an increased sorting efficiency of the sorting system.

In a second aspect, referring to fig. 1 and 5, an embodiment of the present application provides a sorting system including the cargo carrying device 100, a traction guide 400, and a triggering assembly (not shown); the loading device 100 is movable along the traction rail 400 to transport the goods in the loading device 100 to a sorting address; the trigger assembly comprises a first trigger assembly (not shown in the figure) and a second trigger assembly (not shown in the figure), and the first trigger assembly triggers the opening and closing assembly to enable the bearing plate to be switched from the closed position to the open position when the bearing plate is at the sorting address; the second trigger component triggers the opening and closing component to enable the bearing plate to be switched from the opening position to the closing position.

In some embodiments of the present application, the first trigger assembly includes a drive member and a trigger member, the trigger member having a trigger position and a non-trigger position; the driving member controls the trigger member to switch back and forth between the trigger position and the non-trigger position, and the trigger member controls the supporting plate 150 to switch from the closed position to the open position when the trigger member is located at the trigger position.

In some embodiments of the present application, the second trigger assembly includes a guide surface that controls the support plate to switch from the open position to the closed position. Specifically, the driving member includes a push rod, and the trigger member includes an inclined plate. The push rod is connected to the inclined plate.
