Description

Technical Field

[0001] This application relates to the technical field of sorting equipment, and in particular to a transmission component of a sorting machine. Background Art

[0002] An automatic sorting machine is an efficient logistics processing device, mainly composed of four core components: a control device, a sorting device, a transmission device, and a sorting chute. The transmission device is responsible for the conveying of goods, while the sorting device and the sorting chute cooperate to ensure that different goods can be accurately conveyed to the designated sorting chute. The control device is responsible for identifying, receiving, and processing sorting signals to achieve precise control of the entire sorting process. These components are interconnected through a computer network, combined with automation control technology and automatic processing links of manipulators, to jointly form a complete automatic sorting system.

[0003] In the existing technology, the transmission device of the sorting machine mainly relies on a conveyor belt, and the conveyor belt usually adopts chain drive or belt drive technology. Chain drive is known for its simple structure and strong load-bearing capacity, but after long-term operation, the wear problem of the chain will lead to a decrease in conveying accuracy, which in turn affects the sorting accuracy and efficiency of the sorting machine. Although belt drive has high flexibility and low cost, when bearing a large load, the phenomenon of belt slipping occurs frequently, which will also reduce the running accuracy of the conveyor belt, resulting in a decrease in conveying accuracy and having an adverse impact on the overall performance of the sorting machine. After long-term operation, the transmission devices of existing sorting machines will all have a decrease in transmission accuracy due to wear problems, which will affect the conveying accuracy of the conveyor belt and thus have an impact on the working efficiency and sorting accuracy of the sorting machine. Summary of the Invention

[0004] This application provides a transmission component of a sorting machine, the purpose of which is to change the driving method, ensure the conveying accuracy of the conveyor belt, and thus ensure the working efficiency of the sorting machine.

[0005] A transmission component of a sorting machine provided by this application adopts the following technical solution:

[0006] A transmission component of a sorting machine includes a fixed frame, a main conveyor belt is sleeved outside the fixed frame, and the main conveyor belt is slidably connected to the fixed frame along its own length direction; a linear driving mechanism is arranged inside the fixed frame, the driving direction of the linear driving mechanism is arranged along the length direction of the fixed frame, an automatic connection mechanism is arranged between the main conveyor belt and the linear driving mechanism, and the automatic connection mechanism is used to automatically establish or cut off the connection between the linear driving mechanism and the main conveyor belt; a plurality of sorting conveyor belts are arranged on the main conveyor belt, the conveying direction of the sorting conveyor belts is arranged along the width direction of the main conveyor belt, and the plurality of sorting conveyor belts are arranged at intervals in sequence along the length direction of the main conveyor belt.

[0007] By adopting the above technical solution, firstly, the automatic connection mechanism, the linear drive mechanism and the main conveyor belt cooperate. When the automatic connection mechanism connects the linear drive mechanism and the main conveyor belt, the linear drive mechanism pushes or pulls the main conveyor belt in a straight line direction. At this time, since the main conveyor belt is slidably connected to the fixed frame, the main conveyor belt will slide on the fixed frame along its own length direction, thereby realizing the driving function of the main conveyor belt. Secondly, a plurality of sorting conveyor belts are arranged on the main conveyor belt, and each sorting conveyor belt is independent of each other. This makes it possible for the corresponding sorting conveyor belt to work when the goods are placed on the corresponding sorting conveyor belt or several adjacent sorting conveyor belts, and the goods can be transported to one side of the width direction of the main conveyor belt.

[0008] Through the cooperation of the main conveyor belt and several sorting conveyor belts, the main conveyor belt transports the goods forward. When the goods pass through the corresponding sorting crossing or the corresponding unloading channel, the corresponding sorting conveyor belt transports the goods to the corresponding sorting crossing or the unloading channel, thus realizing the sorting function.

[0009] Since the linear drive mechanism is used to drive the main conveyor belt, replacing the existing chain drive or belt drive drive method, the linear drive method can reduce the wear of the transmission components, ensure the conveying accuracy of the main conveyor belt, and thus ensure the working efficiency and sorting accuracy of the sorting machine.

[0010] Optionally, the automatic connection mechanism includes a plurality of secondary magnetic plates, and the plurality of secondary magnetic plates are all arranged on the inner side wall of the main conveyor belt, and the plurality of secondary magnetic plates are arranged in sequence and spaced apart along the length direction of the main conveyor belt; the automatic connection mechanism also includes an electromagnetic plate, and the secondary magnetic plate is attracted to the electromagnetic plate, and the electromagnetic plate is located on the upper side or the lower side of the corresponding secondary magnetic plate, and the linear drive mechanism is connected to the electromagnetic plate, and the linear drive mechanism is used to drive the electromagnetic plate to move along the length direction of the fixed frame.

[0011] By adopting the above technical solution, the automatic connection mechanism cooperates with the electromagnetic plate and several secondary magnetic plates. Under the drive of the linear drive mechanism, the electromagnetic plate can be aligned with the corresponding secondary magnetic plate. When the electromagnetic plate is powered on, the corresponding secondary magnetic plate and the electromagnetic plate are attracted to each other, so that the connection between the linear drive mechanism and the main conveyor belt can be established, and then the linear drive mechanism can drive the main conveyor belt. After the linear drive mechanism moves to the full stroke, the electromagnetic plate is powered off, and the connection between the linear drive mechanism and the main conveyor belt is disconnected, and the linear drive mechanism drives the electromagnetic plate to reset. Then repeat the above steps, and the linear drive mechanism can realize the drive of the main conveyor belt.

[0012] Optionally, the automatic connection mechanism includes a plurality of push plates, all of the plurality of push plates are arranged on the inner side wall of the main conveyor belt, and the plurality of push plates are sequentially arranged at intervals along the length direction of the main conveyor belt; the automatic connection mechanism further includes a mounting seat, the mounting seat is connected to the linear drive mechanism, a switching plate is arranged on the mounting seat, the upper end or the lower end of the switching plate is located between two adjacent corresponding push plates, and the switching plate abuts against the corresponding push plate along the length direction of the fixed frame; the switching plate is slidably connected to the mounting seat in the vertical direction, and a switching drive member for driving the switching plate to move in the vertical direction is arranged on the mounting seat.

[0013] By adopting the above technical solution, the automatic connection mechanism cooperates with a plurality of push plates through the connection switching assembly. The connection switching assembly includes a switching plate, a mounting seat and a switching drive member. Driven by the switching drive member, the switching plate can move in the vertical direction, which enables the upper end or the lower end of the switching plate to be inserted between two adjacent push plates.

[0014] After the upper end or the lower end of the switching plate is inserted between two adjacent corresponding push plates, driven by the linear drive mechanism, the switching plate moves along the length direction of the fixed frame. At this time, the switching plate will abut against the corresponding push plate and push the corresponding push plate to move along the length direction of the fixed frame, thereby enabling the main conveyor belt to convey forward.

[0015] When the linear drive mechanism moves to the full stroke and the switching plate moves forward to the end, at this time the switching drive member drives the switching plate to move downward. At this time, the lower end of the switching plate is inserted between two adjacent push plates. Similarly, when the linear drive mechanism drives the switching plate in the reverse direction, the switching plate can continue to push the corresponding push plate to realize the forward conveying of the main conveyor belt. This can realize the continuous operation of the main conveyor belt.

[0016] Moreover, since the main conveyor belt is driven by a pushing method, the linear drive mechanism can bear a greater load, and thus the main conveyor belt can convey more commodities.

[0017] Optionally, a switching hole is formed through the mounting seat in the vertical direction, the switching plate is inserted and matched with the switching hole, and the switching plate is slidably connected to the inner side wall of the switching hole in the vertical direction.

[0018] By adopting the above technical solution, the formation of the switching hole on the mounting seat provides an installation space for the switching plate to ensure that the switching plate can slide in the vertical direction. Moreover, the switching hole can guide the movement of the switching plate, which can improve the stability of the movement of the switching plate.

[0019] Optionally, the switching board includes a hidden tube, a first board, and a second board. The hidden tube is vertically arranged and is slidably connected to the mounting base in the vertical direction. The switching driving member is connected to the hidden tube. The first board is inserted and matched with the upper end of the hidden tube, and the second board is inserted and matched with the lower end of the hidden tube. Moreover, both the first board and the second board are slidably connected to the hidden tube in the vertical direction. A first driving member and a second driving member are arranged in the hidden tube. The driving directions of both the first driving member and the second driving member are arranged in the vertical direction. The first driving member is connected to the first board, and the second driving member is connected to the second board.

[0020] By adopting the above technical solution, through the cooperative arrangement of the hidden tube, the first board, the second board, the first driving member, and the second driving member, under the action of the first driving member and the second driving member, both the first board and the second board can be independently lifted and lowered, and thus can be retracted into the hidden tube or extended out of the hidden tube.

[0021] When both the first board and the second board are retracted into the hidden tube, the interference during the installation of the switching board can be reduced at this time, which is convenient for the installation of the switching connecting piece. When both the first board and the second board extend out of the hidden tube, at this time, the first board, the second board, and the hidden tube cooperate to realize the function of the switching board.

[0022] Optionally, the first driving member includes a driving electromagnet, a return spring, and an auxiliary magnetic plate. The driving electromagnet is arranged in the hidden tube and is located below the first board. The auxiliary magnetic plate is arranged on the lower side of the first board. The return spring is located between the driving electromagnet and the auxiliary magnetic plate, and the lower end of the return spring is connected to the driving electromagnet, and the upper end is connected to the auxiliary magnetic plate.

[0023] By adopting the above technical solution, through the cooperation of the driving electromagnet, the return spring, and the auxiliary magnetic plate, when the driving electromagnet is powered on, the driving electromagnet attracts the auxiliary magnetic plate, and at this time, the first board moves vertically downward to be retracted into the hidden tube. When the driving electromagnet is powered off, at this time, under the action of the return spring, the first board automatically resets upward to extend out of the hidden tube, which can realize the function of the first driving member.

[0024] Optionally, a plurality of insertion blocks are further arranged on the inner side wall of the main conveyor belt. Insertion slots are opened at both the upper end and the lower end of the switching board. There is one insertion slot that is inserted and matched with the corresponding insertion block in the vertical direction.

[0025] By adopting the above technical solution, through the cooperative arrangement of the insertion block and the insertion slot, when the switching board rises or falls in the vertical direction, the insertion block can be inserted and matched with the corresponding insertion slot.

[0026] Since the switching plate pushes the corresponding push plate to move, when the main conveyor belt stops, the main conveyor belt has the inertia to continue moving, which may cause problems with the positioning accuracy of the main conveyor belt. However, through the cooperation of the plug slot and the plug block, when the main conveyor belt stops, the switching plate fixes the plug block, which can prevent the main conveyor belt from continuing to move due to inertia, thereby improving the positioning accuracy of the main conveyor belt.

[0027] Optionally, the plug-in block is slidably connected to the main conveyor belt along the width direction of the main conveyor belt, and the plug-in block is detachably connected to the main conveyor belt.

[0028] By adopting the above technical solution, since the plug-in block can be slidably connected to the main conveyor belt along the width direction of the main conveyor belt, it is convenient to slide and adjust the position of the plug-in block along the width direction of the main conveyor belt, so as to facilitate accurate positioning of the plug-in block and the corresponding plug-in groove.

[0029] Optionally, two sliding guide rails are provided on the fixed frame, and the two sliding guide rails are spaced apart along the width direction of the fixed frame, the main conveyor belt is located between the two sliding guide rails, and the length direction of the sliding guide rails is arranged along the length direction of the main conveyor belt; the sliding guide rail is provided with a guide groove on one side facing the main conveyor belt, and a plurality of guide wheels are provided on both sides in the width direction of the main conveyor belt, the guide wheels are plug-fitted with the corresponding guide grooves, and the guide wheels are rollingly connected with the inner side walls of the corresponding guide grooves.

[0030] By adopting the above technical solution, the coordinated arrangement of the sliding guide rail and the guide wheel can realize the sliding connection between the main conveyor belt and the fixed frame, and can guide the transportation of the main conveyor belt to ensure that the main conveyor belt can be rotated and transported on the fixed frame.

[0031] Optionally, a plurality of automatic identification cameras are provided on the fixed frame, the automatic identification cameras are located above the main conveyor belt, the automatic identification cameras are arranged toward the main conveyor belt, and the plurality of automatic identification cameras are arranged in sequence and spaced apart along the length direction of the fixed frame.

[0032] By adopting the above technical solution, the setting of the camera is automatically identified. In the process of sorting goods, the data of the goods can be identified and the location of the goods can be determined, so as to facilitate the control of the sorting conveyor belt at the corresponding position to transport the goods to the corresponding sorting gate or unloading channel.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. This application adopts a linear drive method to replace the existing chain drive or belt drive. The linear drive method can reduce the wear of the drive components, improve the conveying accuracy of the main conveyor belt, and thus ensure the working efficiency and sorting accuracy of the sorter.

Under the guiding action of the fixing frame 1, the main conveyor belt 2 moves around the fixing frame 1 along its own length direction, which can drive the main conveyor belt 2 to work. Since each sorting conveyor belt 3 is independent, when the commodity is located on the corresponding sorting conveyor belt 3 or several adjacent sorting conveyor belts 3, the corresponding sorting conveyor belt 3 works and can convey the commodity to one side in the width direction of the main conveyor belt 2.

Driven by the linear actuator 41, the switching plate 532 pushes the corresponding push plate 52 to move, thereby driving the main conveyor belt 2 to move.

[0075] During the reciprocating movement of the linear actuator 41 driving the connection switching component 53, under the action of the switching driving member 535, the driving of the main conveyor belt 2 is realized.

[0076] In this embodiment, referring to Figure 9 , the switching plate 532 includes a hidden tube 5321, a first plate 5322, and a second plate 5323. The hidden tube 5321 is vertically arranged, and the hidden tube 5321 is inserted and matched with the switching hole 5311. The hidden tube 5321 is slidably matched with the inner wall of the switching hole 5311 in the vertical direction, and the switching driving member 535 is connected to the hidden tube 5321.

[0077] Referring to Figure 9 , the first plate 5322 is located at the upper end of the hidden tube 5321. The first plate 5322 is inserted and matched with the hidden tube 5321. The first plate 5322 is slidably connected to the inner wall of the hidden tube 5321 in the vertical direction. A first driving member 533 is arranged in the hidden tube 5321. The driving direction of the first driving member 533 is arranged in the vertical direction, and the first driving member 533 is connected to the first plate 5322.

[0078] Referring to Figure 9 , the second plate 5323 is located at the lower end of the hidden tube 5321. The second plate 5323 is inserted and matched with the hidden tube 5321. The second plate 5323 is slidably connected to the inner wall of the hidden tube 5321 in the vertical direction. A second driving member 534 is arranged in the hidden tube 5321. The driving direction of the second driving member 534 is arranged in the vertical direction, and the second driving member 534 is connected to the second plate 5323.

[0079] Under the action of the first driving member 533 and the second driving member 534, both the first plate 5322 and the second plate 5323 can be independently retracted into the hidden tube 5321 and can also be independently extended from the hidden tube 5321. When both the first plate 5322 and the second plate 5323 are retracted into the hidden tube 5321, it is convenient to install the connection switching assembly 53 at this time. When both the first plate 5322 and the second plate 5323 extend from the hidden tube 5321, the first plate 5322, the second plate 5323 and the hidden tube 5321 cooperate to realize the function of the switching plate 532.

[0080] Referring to Figure 9 , the structures of the first driving member 533 and the second driving member 534 are the same. In this embodiment, the first driving member 533 is taken as an example for illustration. The first driving member 533 includes a driving electromagnet 5331, a return spring 5332 and an auxiliary magnetic plate 5333. The driving electromagnet 5331 is located inside the hidden tube 5321, and the driving electromagnet 5331 is located vertically below the first plate 5322. The driving electromagnet 5331 is arranged at an interval from the first plate 5322. The lower side of the first plate 5322 is connected to the auxiliary magnetic plate 5333. The return spring 5332 is located between the auxiliary magnetic plate 5333 and the driving electromagnet plate, and the upper end of the return spring 5332 is connected to the auxiliary magnetic plate 5333, and the lower end is connected to the driving electromagnet 5331 plate.

[0081] When the driving electromagnet 5331 is energized, the driving electromagnet 5331 attracts the auxiliary magnetic plate 5333. At this time, the first plate 5322 moves vertically downward to be retracted into the hidden tube 5321; when the driving electromagnet 5331 is de-energized, at this time, under the action of the return spring 5332, the first plate 5322 automatically returns upward to extend from the hidden tube 5321, which can realize the function of the first driving member 533.

[0082] Referring to Figure 7 and Figure 8 , a plurality of linear drivers 41 are provided, and a plurality of connection switching assemblies 53 are also provided. The connection switching assemblies 53 are arranged in one-to-one correspondence with the linear drivers 41, and the connection switching assemblies 53 are arranged on the corresponding linear drivers 41.

[0083] Referring to Figure 7 and Figure 8 , a plurality of linear drivers 41 are arranged in sequence along the width direction of the main conveyor belt 2. Among the plurality of linear drivers 41, at least one connection switching assembly 53 corresponding to a linear driver 41 is connected to the first straight section 21 on the main conveyor belt 2, and at least one connection switching assembly 53 corresponding to a linear driver 41 is connected to the second straight section 22 on the main conveyor belt 2. This ensures that during the operation of the main conveyor belt 2, both the first straight section 21 and the second straight section 22 of the main conveyor belt 2 are stressed, which can improve the working stability of the main conveyor belt 2.

[0084] In this embodiment, refer to Figure 5 and Figure 8 The linear drive mechanism 4 also includes an assembly cabinet 42, which is mounted on the fixed frame 1 and is located between the first straight section 21 and the second straight section 22 on the main conveyor belt 2. A plurality of plug-in chambers 421 are formed on the assembly cabinet 42, and the depth direction of the plug-in chambers 421 is arranged along the length direction of the fixed frame 1, and the opening of the plug-in chambers 421 is located on the corresponding side wall of the assembly cabinet 42. The plurality of plug-in chambers 421 are arranged in sequence along the width direction of the main conveyor belt 2. The plug-in chambers 421 are arranged one by one with the linear drive 41, and the linear drive 41 is plugged and matched with the corresponding plug-in chambers 421. The linear drive 41 is located in the corresponding plug-in chamber 421, and the linear drive 41 is connected to the assembly cabinet 42. The assembly cabinet 42 is reserved with a space for the switching plate 532 and the mounting seat 531 to ensure that the switching plate 532 and the mounting seat 531 can work normally. The arrangement of the assembly cabinet 42 facilitates the installation and positioning of a plurality of linear drives 41 in the same linear drive mechanism 4.

[0085] Reference Figure 7 and Figure 8 The assembly cabinet 42 further includes a locking plate 422, which closes the openings of the plurality of plug-in chambers 421. The locking plate 422 is plugged with the assembly cabinet 42 along the width direction of the main conveyor belt 2, and the locking plate 422 is connected to the assembly cabinet 42 by bolts. After the plurality of linear actuators 41 are installed, the locking plate 422 is inserted and locked, which can improve the stability of the installation of the plurality of linear actuators 41.

[0086] In this embodiment, refer to Figure 5 A plurality of linear drive mechanisms 4 are provided, and the plurality of linear drive mechanisms 4 are sequentially spaced apart along the length direction of the fixing frame 1 .

[0087] The implementation principle of the embodiment of the present application is as follows: when the sorting machine is sorting goods, the goods are placed on the transmission assembly, the automatic recognition camera 7 automatically recognizes the information of the goods and the information of the sorting conveyor belt 3 where the goods are located, and transmits the data to the host computer, which matches the corresponding unloading position of the goods according to the goods data. Under the conveyance of the main conveyor belt 2, when the goods move to the corresponding unloading position, the main conveyor belt 2 is paused, and the corresponding sorting conveyor belt 3 starts to unload the goods.

[0088] During the operation of the main conveyor belt 2, each linear drive mechanism 4 alternately pushes the first straight section 21 and the second straight section 22 of the main conveyor belt 2 in sequence, and during this process, the main conveyor belt 2 is driven. Since the linear drive 41 adopts a linear module driven by a servo motor, the transmission accuracy of the main conveyor belt 2 is ensured.

[0089] Embodiment 3: A transmission assembly of a sorting machine. Refer to Figure 10 , the difference between this embodiment and Embodiment 2 is that: a plurality of insertion blocks 521 are arranged on the push plate 52, and the plurality of insertion blocks 521 are arranged at intervals in the length direction of the push plate 52. The insertion block 521 is slidably connected to the corresponding push plate 52 in the length direction of the push plate 52, and the insertion block 521 is connected to the corresponding push plate 52 by bolts. When the bolts are loosened, it is convenient to slide and adjust the position of the insertion block 521 in the length direction of the push plate 52, so as to facilitate the alignment of the insertion block 521 with the corresponding switching plate 532; after the insertion block 521 is aligned with the corresponding switching plate 532, tighten the bolts to fix the insertion block 521.

[0090] Refer to Figure 10 and Figure 11 , insertion slots 5324 are provided at the upper end of the first plate 5322 and the lower end of the second plate 5323, and the insertion slots 5324 are arranged corresponding to the insertion blocks 521. When the switching driving member 535 drives the switching plate 532 to move vertically upward, the insertion slot 5324 on the first plate 5322 is inserted and matched with the corresponding insertion block 521; when the switching driving member 535 drives the switching plate 532 to move vertically downward, the insertion slot 5324 on the second plate 5323 is inserted and matched with the corresponding insertion block 521.

[0091] The implementation principle of the embodiment of the present application is that: during the process of directly pushing the corresponding push plate 52 to move by the switching plate 532, when the main conveyor belt 2 pauses, the main conveyor belt 2 has the inertia of continuing to move, which may cause problems with the positioning accuracy of the main conveyor belt 2. Through the cooperation of the insertion slot 5324 and the insertion block 521, when the main conveyor belt 2 pauses, the switching plate 532 fixes the insertion block 521, which can prevent the main conveyor belt 2 from continuing to move due to inertia, and can improve the positioning accuracy of the main conveyor belt 2.

[0092] The embodiments of this specific implementation manner are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. The same components are denoted by the same reference numerals. Therefore: all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
