Description

Technical Field

[0001] The utility model relates to a turning mechanism, a sorting trolley and a sorting system. Background Art

[0002] With the rapid development of e-commerce and express delivery industries, automated sorting systems can quickly sort parcels and items, and have been widely used. During the sorting process, the material sorting equipment carries the parcel along the track of the sorting system. After the material sorting equipment reaches the predetermined sorting channel, it can automatically push the parcel into the sorting channel. In order to reduce the floor space occupied by the sorting system, there are sorting carts that can perform bidirectional flipping of trays, and corresponding sorting channels can be set on both sides of the track on which the sorting cart travels.

[0003] Currently on the market, sorting carts with two-way flip pallets usually have drive equipment installed on the cart frame to provide power for the pallet to rotate to both sides, and then complete the flipping with the help of the transmission structure and the pressure brought by the materials carried on the pallet. In this process, the weight of the material will affect the flipping speed of the pallet: when the material weight is heavier, the pallet flips faster; conversely, when the material weight is lighter, the flipping speed of the pallet will also be slower accordingly. When the sorting cart is driving, the package needs to fall accurately to the specified position, and the flipping pallet must be flipped accurately and on time. The current flipping structure is prone to missorting of materials. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the current flipping structure of a sorting trolley which needs to travel and complete sorting at the same time easily causes missorting of materials, and to provide a flipping mechanism, a sorting trolley and a sorting system.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A flipping mechanism is used for a sorting trolley, the flipping mechanism includes a tray and a base, the flipping mechanism includes a motor, and the motor is installed in the base; the tray includes a loading portion and a connecting portion at the bottom, and the connecting portion is connected to the bottom of the loading portion; the output shaft of the motor is directly connected to the connecting portion, and drives the tray to rotate in a clockwise direction and a counterclockwise direction, so as to drive the tray to flip and reset to both sides.

[0007] In this solution, the motor is directly connected to the connection part of the pallet and drives the pallet to flip. The connection structure is simple and reliable. The motor controls the flipping speed of the pallet, so that the flipping speed of the pallet is stable, avoiding the weight of the material from affecting the flipping speed of the pallet, ensuring that the material slides down to the designated sorting channel, and the sorting trolley can continue to move along the track without stopping at the corresponding sorting position. The flipping angle of the pallet can be controlled by the angle of the motor, without the need to set a buffer in the flipping direction of the pallet, further simplifying the overall structural setting of the sorting trolley. The motor is used to reset the loading part, and there is no need to set a corresponding reset area in the sorting system, simplifying the structural setting of the sorting system.

[0008] Preferably, the connecting portion is bent to form a first bending surface and a second bending surface, the first bending surface is attached to and connected to the bottom of the loading portion, the second bending surface forms an angle with the first bending surface, and the second bending surface is used to connect the output shaft of the motor.

[0009] In this solution, the connecting part is formed by bending, which simplifies the structural setting of the connecting part and facilitates the manufacture of the connecting part; at the same time, the first bending surface is attached to and connected to the bottom of the loading part, increasing the connection area between the connecting part and the loading part, which is beneficial to the connection reliability between the connecting part and the loading part.

[0010] Preferably, a limiting hole is provided on the second bending surface, and the connecting portion is connected to the output shaft of the motor through the limiting hole.

[0011] In the present solution, by providing the limiting holes, the limiting holes can be manufactured by cutting, thereby facilitating the manufacture of the connecting part and the connection structure between the connecting part and the motor.

[0012] Preferably, in an axial direction perpendicular to the output shaft of the motor, the first bending surface is bent to form a third bending surface, and both ends of the third bending surface extend to the second bending surface.

[0013] In this solution, by setting a third bending surface, the two ends of the third bending surface can support the second bending surface, and at the same time can reduce the risk of deformation of the first bending surface, which is beneficial to the overall strength of the connecting part; the connecting part is formed by bending, which simplifies the structural setting of the connecting part and facilitates the manufacture of the connecting part.

[0014] Preferably, the connecting portion is provided with a to-be-detected portion on one side or both sides in the rotation direction, and the to-be-detected portion extends outward along the edge of the connecting portion;

[0015] The flipping mechanism also includes a detection element;

[0016] When the tray is turned over to one side or both sides, the detection element detects the portion to be detected, and the motor stops driving the tray to continue turning over.

[0017] In this solution, through the above settings, when the flip mechanism is started, the motor rotates in the clockwise and counterclockwise directions. When the detection elements on one or both sides detect the part to be detected, the output shaft of the motor is zero-positioned to quickly identify the angle of the motor output shaft and the position of the tray, which is convenient for the start-up setting of the sorting trolley. Alternatively, when the detection elements on one or both sides detect the part to be detected, it is determined that the motor is at the extreme position of clockwise rotation or counterclockwise rotation, and the motor stops rotating in this direction to avoid damage to the detection elements or the part to be detected.

[0018] Preferably, the connecting portion forms a bending surface, and the bending surface is used to connect the output shaft of the motor;

[0019] The to-be-detected portion is arranged on the side of the bending surface;

[0020] The bending surface is also provided with an avoidance groove, which is concave inwardly along the side of the bending surface.

[0021] In this solution, when the tray is turned over to the point where the detection element can detect the part to be detected, an avoidance groove is provided to prevent the connection part from contacting or colliding with the detection element. The avoidance groove and the part to be detected can be manufactured by cutting, thereby facilitating the manufacture of the connection part and the connection structure between the connection part and the motor.

[0022] Preferably, limiting portions are further provided on the base on both sides of the flipping direction of the tray, wherein the limiting portions have limiting surfaces extending obliquely downward from a direction close to the tray, and the limiting surfaces are used to limit the maximum flipping angle of the tray.

[0023] In this solution, through the above arrangement, the flipping position of the pallet is hard-limited by the mechanical structure, reducing the risk of damage to the flipping mechanism caused by excessive flipping of the pallet. By setting the limiting surface, the contact area between the limiting part and the pallet is increased, thereby reducing the impact force caused by the limiting part on the pallet, thereby protecting the pallet and reducing the risk of deformation of the pallet.

[0024] A sorting trolley comprises a frame, the frame travels on a travel track of the sorting trolley, the sorting trolley comprises the above-mentioned tipping mechanism, wherein the tipping mechanism is arranged on the frame.

[0025] In this solution, the motor can drive the tray to flip and reset to both sides, so that sorting channels for material sorting can be set on both sides of the track where the sorting trolley travels, which is conducive to the compact structure of the sorting system. The motor is directly connected to the connection part of the tray and drives the tray to flip, so the connection structure is simple and reliable; the motor controls the flipping speed of the tray, so that the flipping speed of the tray is stable, avoiding the weight of the material from affecting the flipping speed of the tray, and ensuring that the material slides down to the designated sorting channel. At the same time, the sorting trolley can continue to travel along the track without stopping at the corresponding sorting position; and the flipping angle of the tray can be controlled by the angle of the motor, without the need to set a buffer in the flipping direction of the tray, further simplifying the overall structural setting of the sorting trolley. The resetting of the loading part is achieved by the motor, and there is no need to set a corresponding reset area in the sorting system, which simplifies the structural setting of the sorting system.

[0026] Preferably, the base is connected to the frame in a floating manner in the height direction;

[0027] In the width direction of the sorting trolley, the base is also connected with a matching portion, and the matching portions are respectively arranged on both sides of the base and extend outward along both sides of the base, so that the tray can be lifted relative to the frame.

[0028] In this solution, the sorting trolley is driven by a motor to flip the tray, and the overall weight of the motor is heavy. Through the above arrangement, when weighing the sorting trolley and the items carried, the base, the motor installed in the base, the tray connected to the motor, and the materials carried can be weighed separately without weighing the frame, so that the weight that needs to be measured by the weighing device of the sorting trolley is small, which is conducive to accurate measurement of the materials carried by the sorting trolley.

[0029] Preferably, the base is connected to the frame via a connecting rod, and both ends of the connecting rod are rotatably connected relative to the frame and the base, respectively, so that the base can be lifted relative to the frame.

[0030] In this solution, through the above-mentioned arrangement, the connection between the base and the frame can still be maintained during the process of the base being lifted relative to the frame, thereby ensuring a reliable connection between the base and the frame and the stability of the sorting trolley during driving.

[0031] Preferably, the frame includes a running part and a mounting part at the bottom.

[0032] The mounting portion includes a bottom plate connected to the traveling portion, and an extension portion provided on one side of the bottom plate in the length direction of the sorting trolley, wherein the extension portion is located above the bottom plate and extends upward in the height direction;

[0033] Two connecting rods are respectively arranged on both sides of the sorting trolley in the width direction, and the connecting rods are rotatably connected to the extending parts.

[0034] In this solution, the extension part is arranged on one side of the base in the length direction of the sorting trolley, thereby avoiding occupying the space in the width direction of the sorting trolley, avoiding interference between the extension part and the connecting rod and the flip mechanism, and simplifying the structural setting of the sorting trolley. At the same time, through the above arrangement, it is also ensured that the base can be erected on the bottom plate, which is beneficial to the stability of the sorting trolley during driving.

[0035] Preferably, a buffer is provided on the upper surface of the bottom plate.

[0036] In this solution, through the above-mentioned arrangement, when the base is changed from being lifted relative to the bottom plate to being erected on the bottom plate, the relative impact force between the base and the bottom plate is reduced, thereby protecting the base, the bottom plate and the motor, thereby facilitating the service life of the sorting trolley.

[0037] A sorting system, the sorting system comprising a sorting trolley weighing device, the sorting trolley weighing device further comprising a weighing sensor, the sorting trolley weighing device weighs the above-mentioned sorting trolley through the weighing sensor;

[0038] The weighing device of the sorting trolley includes a weighing bracket, and the weighing bracket includes a first part, the first part extends horizontally in the driving direction of the sorting trolley, and the first part is connected to the weighing sensor;

[0039] The top of the first part has a mating surface that is mated with the mating portion, and the mating surface is higher than the running height of the mating portion at a position other than the first part;

[0040] The sorting trolley comprises a matching portion, which acts on the first portion in a vertical direction and applies pressure of at least the tray portion to the first portion.

[0041] In this solution, the sorting trolley drives the tray to flip through a motor, and the overall weight of the motor is relatively heavy. Through the above arrangement, when weighing the sorting trolley and the items it carries, the base, the motor installed in the base, the tray connected to the motor, and the materials carried can be weighed separately without weighing the frame, so that the weight that needs to be measured by the weighing device of the sorting trolley is small, which is conducive to the accurate measurement of the materials carried by the sorting trolley; at the same time, by setting the first part extending in the horizontal direction, the weighing sensor can measure the weight of the materials carried by the sorting trolley within a period of time, reducing the interference of the sorting trolley to the measuring structure during driving, which is conducive to the accurate measurement of the weight of the materials carried by the sorting trolley.

[0042] Preferably, the base is connected to the frame via a connecting rod, and both ends of the connecting rod are rotatably connected relative to the frame and the base, respectively, so that the base can be lifted relative to the frame;

[0043] When the matching portion acts on the first portion, there is a gap between the bottom of the base and the frame;

[0044] When the matching portion does not act on the first portion, the base is mounted on the frame.

[0045] In this solution, when the matching part acts on the first part, the weighing sensor weighs the materials carried by the sorting trolley, and the base is lifted relative to the frame, so that the base, motor, tray and materials can be weighed separately without weighing the frame, so that the weight that needs to be measured by the weighing device of the sorting trolley is smaller, which is conducive to the accurate measurement of the materials carried by the sorting trolley; during this process, the connection between the base and the frame can still be maintained, thereby ensuring a reliable connection between the base and the frame and the stability of the sorting trolley during driving.

[0046] Preferably, the weighing bracket further includes a second part and a third part;

[0047] In the travel direction of the sorting vehicle, the second portion extends upward to be flush with the first portion, and the third portion extends downward from a height flush with the first portion;

[0048] When the base is mounted on the frame, the starting position of the second portion is not higher than the bottom of the matching portion.

[0049] In this solution, through the above-mentioned settings, in the driving direction of the sorting trolley, the matching part matches with the second part, the first part and the third part in sequence. When the matching part matches with the second part, as the sorting trolley continues to move, the base is gradually lifted relative to the frame; when the matching part matches with the matching surface of the first part, the weighing sensor weighs the materials carried by the sorting trolley; when the matching part matches with the third part, the base is gradually lowered relative to the frame, reducing the impact force between the base and the frame, reducing the risk of damage to the base, frame and motor, and is beneficial to the service life of the sorting trolley.

[0050] Preferably, the weighing bracket includes a first supporting portion, and the second portion and the third portion are respectively connected to a track on which the sorting trolley travels through the first supporting portion.

[0051] In this solution, through the above arrangement, the second part and the third part are directly connected to the track, which simplifies the connection structure of the second part and the third part and facilitates the overall arrangement of the sorting system.

[0052] Preferably, the weighing sensor is arranged below the track on which the sorting trolley travels;

[0053] The weighing bracket also includes a second supporting part, the top of the second supporting part is connected to the first part, the second supporting part extends downward on both sides of the track, and the weighing sensor is connected to the middle of the bottom of the second supporting part.

[0054] In this solution, the above-mentioned settings facilitate the structural arrangement of the track, and there is no need to set up additional weighing tracks. The weighing sensor is arranged under the track, and the height space is used to realize the compact arrangement of the sorting system; the weighing sensor is prevented from interfering with the driving route of the sorting trolley, thereby simplifying the overall layout of the sorting system.

[0055] Preferably, the matching portion is a matching wheel.

[0056] In this solution, through the above-mentioned arrangement, it is convenient for the matching part to match with the second part, the first part and the third part in sequence, which is beneficial to the smooth driving of the sorting trolley, reduces the risk of bumps of the sorting trolley, and is beneficial to the smooth transportation of materials.

[0104] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0105] Example 1

[0106] This embodiment provides a flip mechanism 100, such as Figure 1 As shown, for a sorting trolley 200, the flipping mechanism 100 includes a tray 1 and a base 2, and the flipping mechanism 100 includes a motor 3, which is installed in the base 2; the tray 1 includes a loading portion 11 and a connecting portion 12 at the bottom, and the connecting portion 12 is connected to the bottom of the loading portion 11; the output shaft of the motor 3 is directly connected to the connecting portion 12, and drives the tray 1 to rotate in a clockwise direction and a counterclockwise direction to drive the tray 1 to flip and reset to both sides. In this embodiment, the motor 3 is a reduction motor, which has a simple structure, occupies a small space, and can be used for different loads. In other alternative embodiments, other motors compatible with the circuit system of the sorting system 300 can also be used.

[0107] The motor 3 is directly connected to the connection part 12 of the tray 1 and drives the tray 1 to flip. The connection structure is simple and reliable. The motor 3 controls the flipping speed of the tray 1, so that the flipping speed of the tray 1 is stable, avoiding the weight of the material from affecting the flipping speed of the tray 1, ensuring that the material slides down to the designated sorting channel, and the sorting trolley 200 can maintain running along the track 301 without stopping at the corresponding sorting position. The flipping angle of the tray 1 can be controlled by the angle of the motor 3, and there is no need to set a buffer in the flipping direction of the tray 1, further simplifying the overall structural setting of the sorting trolley 200. The motor 3 realizes the reset of the loading part 11, and there is no need to set a corresponding reset area in the sorting system 300, simplifying the structural setting of the sorting system 300.

[0108] As a preferred implementation, Figure 2 As shown, the connecting portion 12 is bent to form a first bending surface 121 and a second bending surface 122 . The first bending surface 121 is attached to and connected to the bottom of the loading portion 11 . The second bending surface 122 forms an angle with the first bending surface 121 . The second bending surface 122 is used to connect to the output shaft of the motor 3 .

[0109] The connecting portion 12 is formed by bending, which simplifies the structural setting of the connecting portion 12 and facilitates the manufacture of the connecting portion 12; at the same time, the first bending surface 121 is attached to and connected to the bottom of the loading portion 11, increasing the connection area between the connecting portion 12 and the loading portion 11, which is beneficial to the connection reliability between the connecting portion 12 and the loading portion 11.

[0110] In this embodiment, the first bending surface 121 and the second bending surface 122 are perpendicular to each other. In other alternative embodiments, the first bending surface 121 and the second bending surfaces 122 on both sides may form mutually symmetrical obtuse angles or acute angles, or other transition surfaces may be provided between the first bending surface 121 and the second bending surface 122.

[0111] As a preferred implementation, Figure 2 As shown, a limiting hole 1221 is provided on the second bending surface 122, and the connecting portion 12 is connected to the output shaft of the motor 3 through the limiting hole 1221. The shape of the limiting hole 1221 matches the output shaft of the motor 3.

[0112] By providing the limiting hole 1221 , the limiting hole 1221 can be manufactured by cutting, thereby facilitating the manufacture of the connecting portion 12 and the connection structure between the connecting portion 12 and the motor 3 .

[0113] As a preferred implementation, Figure 1 and Figure 2As shown, in the axial direction perpendicular to the output shaft of the motor 3 , the first bending surface 121 is bent to form a third bending surface 123 , and both ends of the third bending surface 123 extend to the second bending surface 122 .

[0114] By setting the third bending surface 123, the two ends of the third bending surface 123 can support the second bending surface 122, and at the same time can reduce the risk of deformation of the first bending surface 121, which is beneficial to the overall strength of the connecting part 12; the connecting part 12 is formed by bending, which simplifies the structural setting of the connecting part 12 and facilitates the manufacture of the connecting part 12.

[0115] As a preferred implementation, both ends of the third bending surface 123 may also be connected to the second bending surface 122 by welding.

[0116] As a preferred implementation, Figure 1 and Figure 2 As shown, the connecting portion 12 is provided with a portion to be detected 124 on one side or both sides in the rotation direction, and the portion to be detected 124 extends outward along the edge of the connecting portion 12; the flipping mechanism 100 also includes a detection element 4; when the tray 1 flips to one side or both sides, the detection element 4 detects the portion to be detected 124, and the motor 3 stops driving the tray 1 to continue flipping. In this embodiment, the detection element 4 is a photoelectric sensor, so the portion to be detected 124 is set as a protrusion mechanism that can be detected by the photoelectric sensor. In other alternative embodiments, the detection element 4 is set on the side wall of the base 2, and the detection element can also be set as a Hall sensor, an ultrasonic sensor, etc. In this case, the portion to be detected needs to be set as a corresponding structure that can be applicable to the detection element.

[0117] Through the above arrangement, when the flip mechanism 100 is started, the motor 3 rotates in the clockwise and counterclockwise directions. When the detection elements 4 on one or both sides detect the part to be detected 124, the output shaft of the motor 3 is zero-positioned to quickly identify the angle of the output shaft of the motor 3 and the position of the tray 1, which is convenient for the start-up setting of the sorting trolley 100. Alternatively, when the detection elements 4 on one or both sides detect the part to be detected 124, it is determined that the motor 3 is at the extreme position of clockwise rotation or counterclockwise rotation, and the motor 3 stops rotating in this direction to avoid damage to the detection elements 4 or the part to be detected 124.

[0118] In actual use, when the motor 3 flips the tray 1, the flipping angle of the tray 1 can be controlled by controlling the angle of rotation of the output shaft of the motor 3. When the tray 1 is flipped, it is not necessary to rely on the cooperation between the detection element 4 and the part to be detected 124 to determine whether the tray has been flipped, but directly preset the motor 3. At this time, the detection element 4 and the part to be detected 124 are only used to zero the output shaft of the motor 3.

[0119] As a preferred implementation, Figure 1 and Figure 2 As shown, the connecting portion 12 forms a bending surface, and the bending surface is used to connect the output shaft of the motor 3; the portion to be detected 124 is arranged on the side of the bending surface; and the bending surface is also provided with an avoidance groove 125, which is recessed inward along the side of the bending surface. In this embodiment, the bending surface is the second bending surface 122. In other alternative embodiments, the portion to be detected 124 can be arranged on the third bending surface 123 or the first bending surface 121 and extend outward.

[0120] When the tray 1 is turned over to the point where the detection element 4 can detect the portion to be detected 124, the avoidance groove 125 is provided to prevent the connection portion 12 from contacting or colliding with the detection element 4. The avoidance groove 125 and the portion to be detected 124 can be manufactured by cutting, thereby facilitating the manufacture of the connection portion 12 and the connection structure between the connection portion 12 and the motor 3. In other alternative embodiments, the shape and specifications of the second bending surface 122 can also be set so that the second bending surface 122 does not contact the detection element 4 during the turning of the tray 1.

[0121] As a preferred implementation, Figure 1 As shown, on both sides of the flipping direction of the tray 1, the base 2 is further provided with a limiting portion 5, the limiting portion 5 having a limiting surface 51 extending obliquely downward from the direction close to the tray 1, and the limiting surface 51 is used to limit the maximum flipping angle of the tray 1.

[0122] Through the above configuration, the flipping position of the tray 1 is hard limited by the mechanical structure, reducing the risk of damage to the flipping mechanism 100 caused by excessive flipping of the tray 1. By providing the limiting surface 51, the contact area between the limiting portion 5 and the tray 1 is increased, thereby reducing the impact force caused by the limiting portion 5 on the tray 1, thereby protecting the tray 1 and reducing the risk of deformation of the tray 1.

[0123] As a preferred embodiment, the loading part 11 includes a bottom surface arranged in a horizontal direction and a side wall extending obliquely upward along the bottom surface, and the loading part 11 also includes a receiving groove extending in the width direction W of the sorting trolley 200, the receiving groove penetrates the side wall and the bottom of the receiving groove is flush with the bottom surface of the loading part 11. The receiving groove is used to receive long strips of materials to prevent the materials from rolling in the loading part 11, which is conducive to the smooth transportation of the materials.

[0124] Example 2

[0125] This embodiment provides a sorting vehicle 200, such as Figure 3As shown, the sorting trolley 200 includes a frame 6, and the frame 6 runs on a running track 301 of the sorting trolley 200. The sorting trolley 200 includes the tipping mechanism 100 in Example 1, wherein the tipping mechanism 100 is arranged on the frame 6.

[0126] The motor 3 can drive the tray 1 to flip and reset to both sides, so that sorting channels for material sorting can be set on both sides of the track 301 on which the sorting trolley 200 travels, which is conducive to the compact structure of the sorting system 300. The motor 3 is directly connected to the connection part 12 of the tray 1 and drives the tray 1 to flip, and the connection structure is simple and reliable; the flipping speed of the tray 1 is controlled by the motor 3, so that the flipping speed of the tray 1 is stable, and the weight of the material is prevented from affecting the flipping speed of the tray 1, which can ensure that the material slides down to the designated sorting channel, and the sorting trolley 200 can maintain driving along the track 301 without stopping at the corresponding sorting position; and the flipping angle of the tray 1 can be controlled by the angle of the motor 3, and there is no need to set a buffer in the flipping direction of the tray 1, which further simplifies the overall structural setting of the sorting trolley 200. The reset of the loading part 11 is achieved by the motor 3, and there is no need to set a corresponding reset area in the sorting system 300, which simplifies the structural setting of the sorting system 300.

[0127] As a preferred embodiment, the base 2 is connected to the frame 6 in a floating manner in the height direction; in the width direction W of the sorting trolley 200, the base 2 is also connected to a matching portion 21, which is respectively arranged on both sides of the base 2 and extends outward along both sides of the base 2, so that the tray 1 can be lifted relative to the frame 6. The length direction L of the sorting trolley 200 is consistent with the direction in which the sorting trolley 200 travels, and the width direction W of the sorting trolley 200 is perpendicular to the direction in which the sorting trolley 200 travels.

[0128] The sorting trolley 200 drives the tray 1 to flip through the motor 3, and the motor 3 is heavy overall. Through the above arrangement, when weighing the sorting trolley 200 and the items carried, the base 2, the motor 3 installed in the base 2, the tray 1 connected to the motor 3, and the carried materials can be weighed separately without weighing the frame 6, so that the weight that needs to be measured by the sorting trolley weighing device 9 is small, which is conducive to accurate measurement of the materials carried by the sorting trolley 200.

[0129] In this embodiment, the tray 1 is directly connected to the output shaft of the motor 3, the matching portion 21 is connected to both sides of the base 2, and the base 2 is connected in a floating manner relative to the frame 6 in the height direction, which can simplify the connection structure between the tray 1 and the motor 3. In other alternative embodiments, a transmission mechanism can be provided between the tray 1 and the motor 3 so that the tray 1 is connected in a floating manner relative to the motor 3; in this case, the matching portion 21 can be provided on the tray 1 accordingly.

[0130] As a preferred implementation, Figure 4 , Figure 5 and Figure 6 As shown, the base 2 is connected to the frame 6 through a connecting rod 7, and the two ends of the connecting rod 7 are rotatably connected relative to the frame 6 and the base 2, so that the base 2 can be lifted relative to the frame 6. In this embodiment, two connecting rods 7 are respectively arranged on both sides of the sorting trolley 200 in the width direction W, and the connecting rods 7 on the left and right sides are symmetrically arranged in the horizontal direction, which is conducive to the smooth lifting and lowering of the base 2 relative to the frame 6.

[0131] Through the above arrangement, when the base 2 is lifted relative to the frame 6, the connection between the base 2 and the frame 6 can still be maintained, thereby ensuring a reliable connection between the base 2 and the frame 6 and the stability of the sorting trolley 200 during driving.

[0132] As a preferred implementation, Figure 3-Figure 6 As shown, the frame 6 includes a traveling portion 61 and a mounting portion 62 at the bottom, the mounting portion 62 includes a bottom plate 621 connected to the traveling portion 61, and an extension portion 622 arranged on one side of the bottom plate 621 in the length direction L of the sorting trolley 200, the extension portion 622 is located above the bottom plate 621 and extends upward in the height direction; two connecting rods 7 are respectively arranged on both sides in the width direction W of the sorting trolley 200, and the connecting rods 7 are rotatably connected to the extension portion 622.

[0133] By arranging the extension part 622 on one side of the base 2 in the length direction L of the sorting trolley 200, it is avoided to occupy the space in the width direction W of the sorting trolley 200, and to avoid interference between the extension part 622 and the connecting rod 7 and the flip mechanism 100, thereby simplifying the structural setting of the sorting trolley 200. At the same time, through the above arrangement, it is also ensured that the base 2 can be erected on the bottom plate 621, which is beneficial to the stability of the sorting trolley 200 during driving.

[0134] As a preferred implementation, Figure 4 As shown, a buffer member 8 is disposed on the upper surface of the bottom plate 621. The buffer member 8 may be made of a material having a certain elasticity such as rubber or sponge.

[0135] Through the above arrangement, when the base 2 is lifted relative to the bottom plate 621 and changed to be mounted on the bottom plate 621, the relative impact force between the base 2 and the bottom plate 621 is reduced, thereby protecting the base 2, the bottom plate 621 and the motor 3, thereby facilitating the service life of the sorting cart 200.

[0136] Example 3

[0137] This embodiment provides a sorting system 300, such as Figure 5-Figure 10As shown, the sorting system 300 includes a sorting trolley weighing device 9, and the sorting trolley weighing device 9 also includes a weighing sensor 91. The sorting trolley weighing device 9 weighs the sorting trolley 200 in Example 2 through the weighing sensor 91; the sorting trolley weighing device 9 includes a weighing bracket 92, and the weighing bracket 92 includes a first part 921, and the first part 921 extends in a horizontal direction in the driving direction of the sorting trolley 200, and the first part 921 is connected to the weighing sensor 91; the top of the first part 921 has a mating surface that cooperates with the mating part 21, and the mating surface is higher than the driving height of the mating part at a position other than the first part 921; the sorting trolley 200 includes a mating part 21, and the mating part 21 acts on the first part 921 in the vertical direction and applies pressure of at least part of the tray 1 to the first part 921. In other alternative embodiments, the sorting trolley weighing device 9 of the sorting system 300 can also be used for a non-motor-driven sorting trolley, or a sorting trolley that does not use a tray for flipping, etc.

[0138] When the sorting trolley 200 is traveling on the track 301 and the matching portion 21 does not act on the first part 921, there is a first distance between the lower surface of the matching portion 21 and the upper surface of the track 301, and the trolley is in a normal traveling and non-weighing state; when the matching portion 21 is matched with the matching surface, the traveling portion 61 of the sorting trolley 200 continues to travel along the track 301 extending in the horizontal direction, and the first part 921 is higher than the matching surface than the traveling height of the matching portion at the position other than the first part 921, and at this time there is a second distance between the lower surface of the matching portion 21 and the upper surface of the track 301, wherein the second distance is greater than the first distance, and at this time the base 2 is lifted relative to the frame 6, and the weighing sensor 91 weighs the weight of the material carried by the sorting trolley 200.

[0139] The sorting trolley 200 drives the tray 1 to flip through the motor 3, and the overall weight of the motor 3 is relatively heavy. Through the above-mentioned arrangement, when weighing the sorting trolley 200 and the items carried, the base 2, the motor 3 installed in the base 2, the tray 1 connected to the motor 3, and the materials carried can be weighed separately without weighing the frame 6, so that the weight required to be measured by the sorting trolley weighing device 9 is relatively small, which is conducive to the accurate measurement of the materials carried by the sorting trolley 200; at the same time, by setting the first part 921 extending in the horizontal direction, the weighing sensor 91 can measure the weight of the materials carried by the sorting trolley 200 within a period of time, reducing the interference of the sorting trolley 200 to the measuring structure during driving, which is conducive to the accurate measurement of the weight of the materials carried by the sorting trolley 200.

[0140] As a preferred implementation, Figure 4-Figure 8As shown, the base 2 is connected to the frame 6 via a connecting rod 7, and the two ends of the connecting rod 7 are rotatably connected relative to the frame 6 and the base 2, so that the base 2 can be lifted relative to the frame 6; when the matching portion 21 acts on the first portion 921, there is a gap between the bottom of the base 2 and the frame 6; when the matching portion 21 does not act on the first portion 921, the base 2 is mounted on the frame 6.

[0141] When the matching portion 21 acts on the first part 921, the weighing sensor 91 weighs the material carried by the sorting cart 200, and the base 2 is lifted relative to the frame 6, so that the base 2, the motor 3, the tray 1 and the material can be weighed separately without weighing the frame 6, so that the weight that needs to be measured by the sorting cart weighing device 9 is smaller, which is conducive to the accurate measurement of the material carried by the sorting cart 200; during this process, the connection between the base 2 and the frame 6 can still be maintained, thereby ensuring the reliable connection between the base 2 and the frame 6 and the stability of the sorting cart 200 during driving.

[0142] Specifically, when the matching portion 21 acts on the first portion 921 , the connecting rod 7 extends in the horizontal direction, thereby reducing the interference of the deadweight of the connecting rod 7 on the weighing of the material.

[0143] During installation and debugging of the sorting system 300 , the position and height of the first portion 921 relative to the track 301 can be adjusted to ensure that when the matching portion 21 acts on the first portion 921 , the connecting rod 7 extends in the horizontal direction.

[0144] As a preferred implementation, Figure 7 , Figure 8 and Fig.10 As shown, the weighing bracket 92 also includes a second portion 922 and a third portion 923;

[0145] In the travel direction of the sorting vehicle 200 , the second portion 922 extends upward to be flush with the first portion 921 , and the third portion 923 extends downward from a height flush with the first portion 921 ;

[0146] When the base 2 is mounted on the frame 6 , the starting position of the second portion 922 is not higher than the bottom of the matching portion 21 .

[0147] Through the above arrangement, in the driving direction of the sorting trolley 200, the matching portion 21 matches with the second portion 922, the first portion 921 and the third portion 923 in sequence. When the matching portion 21 matches with the second portion 922, as the sorting trolley 200 continues to drive, the base 2 is gradually lifted relative to the frame 6; when the matching portion 21 matches with the matching surface of the first portion 921, the weighing sensor 91 weighs the material carried by the sorting trolley 200; when the matching portion 21 matches with the third portion 923, the base 2 is gradually lowered relative to the frame 6, reducing the impact force between the base 2 and the frame 6, reducing the risk of damage to the base 2, the frame 6 and the motor 3, and is beneficial to the service life of the sorting trolley 200.

[0148] As a preferred implementation, Figure 7 , Figure 8 and Fig.10 As shown, the weighing bracket 92 includes a first supporting portion 924 , and the second portion 922 and the third portion 923 are respectively connected to the track 301 on which the sorting trolley 200 travels through the first supporting portion 924 .

[0149] Through the above arrangement, the second part 922 and the third part 923 are directly connected to the track 301 , which simplifies the connection structure between the second part 922 and the third part 923 and facilitates the overall arrangement of the sorting system 300 .

[0150] As a preferred implementation, Figure 7 , Figure 8 and Fig.10 As shown, the weighing sensor 91 is arranged below the track 301 on which the sorting trolley 200 travels; the weighing bracket 92 also includes a second support portion 925, the top of the second support portion 925 is connected to the first portion 921, the second support portion 925 extends downward on both sides of the track 301, and the weighing sensor 91 is connected to the middle of the bottom of the second support portion 925.

[0151] The above arrangement facilitates the structural arrangement of the track 301, and there is no need to arrange an additional weighing track 301. The weighing sensor 91 is arranged below the track 301, and the height space is utilized to realize the compact arrangement of the sorting system 300. The weighing sensor 91 is prevented from interfering with the driving route of the sorting trolley 200, thereby simplifying the overall layout of the sorting system 300.

[0152] As a preferred embodiment, the matching portion 21 is a matching wheel, wherein the matching wheel directly matches with the upper surfaces of the second portion 922, the first portion 921 and the third portion 923, and when the sorting trolley 200 travels along the track 301, the matching portion 21 can roll accordingly along the extension direction of the upper surfaces of the second portion 922, the first portion 921 and the third portion 923.

[0153] In other alternative embodiments, the second part 922, the first part 921 and the third part 923 may also be provided with sliding grooves, and the matching portion 21 is configured as a sliding block that matches therewith.

[0154] Through the above arrangement, it is convenient for the matching part 21 to match with the second part 922, the first part 921 and the third part 923 in sequence, which is beneficial to the smooth driving of the sorting cart 200, reduces the risk of bumps of the sorting cart 200, and is beneficial to the smooth transportation of materials.
