Description

Technical Field

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

[0002] The automatic sorting machine is a highly efficient logistics processing equipment, mainly composed of four core components: control device, classification device, transmission device and sorting gate. The transmission device is responsible for the transportation of goods, while the classification device and the sorting gate work together to ensure that different goods can be accurately transported to the designated sorting gate. 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 automated control technology and automatic processing links of the robot, to form a complete automatic sorting system.

[0003] In the existing technology, the transmission device of the sorting machine mainly relies on the 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 it is subjected to a large load, the belt slips frequently, which will also reduce the running accuracy of the conveyor belt, resulting in a decrease in conveying accuracy and an adverse effect on the overall performance of the sorting machine. After a long period of operation, the transmission device of the existing sorting machine will cause a decrease in transmission accuracy due to wear problems, which will affect the conveying accuracy of the conveyor belt, and then affect the working efficiency and sorting accuracy of the sorting machine. Summary of the invention

[0004] The present application provides a transmission assembly for a sorting machine, the purpose of which is to change the driving mode, ensure the conveying accuracy of the conveyor belt, and further ensure the working efficiency of the sorting machine.

[0005] The transmission assembly of a sorting machine provided in this application adopts the following technical solution: A transmission assembly of a sorting machine comprises a fixed frame, a main conveyor belt is sleeved on the outer side of the fixed frame, and the main conveyor belt is slidably connected with the fixed frame along its own length direction; a linear drive mechanism is arranged in the fixed frame, and the driving direction of the linear drive mechanism is arranged along the length direction of the fixed frame, and an automatic connection mechanism is arranged between the main conveyor belt and the linear drive mechanism, and the automatic connection mechanism is used to automatically establish or cut off the connection between the linear drive mechanism and the main conveyor belt; a plurality of sorting conveyor belts are arranged on the main conveyor belt, and 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 in sequence and spaced apart along the length direction of the main conveyor belt.

[0006] 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.

[0007] 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.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] Optionally, the automatic connecting mechanism includes a plurality of push plates, which are all arranged on the inner side wall of the main conveyor belt, and are arranged in sequence and spaced apart along the length direction of the main conveyor belt; the automatic connecting mechanism also includes a mounting seat, which is connected to the linear drive mechanism, and a switching plate is provided on the mounting seat, and the upper or lower end of the switching plate is located between the corresponding two adjacent push plates, and the switching plate is in contact with the corresponding push plate along the length direction of the fixed frame; the switching plate is slidably connected to the mounting seat in a vertical direction, and a switching drive member for driving the switching plate to move in the vertical direction is provided on the mounting seat.

[0012] By adopting the above technical solution, the automatic connecting mechanism cooperates with a plurality of push plates through the connection switching component. The connection switching component 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 or lower end of the switching plate to be inserted between two adjacent push plates.

[0013] When the upper or lower end of the switching plate is inserted between the corresponding two adjacent push plates, the switching plate moves along the length direction of the fixed frame under the drive of the linear drive mechanism. At this time, the switching plate will resist the corresponding push plate and push the corresponding push plate to move along the length direction of the fixed frame, thereby making the main conveyor belt transport forward.

[0014] When the linear drive mechanism moves to the full stroke, the switch plate moves forward to the end, and the switch drive member drives the switch plate to move downward. At this time, the lower end of the switch plate is inserted between two adjacent push plates. Similarly, when the linear drive mechanism drives the switch plate in the reverse direction, the switch plate can continue to push the corresponding push plate to realize the forward conveyance of the main conveyor belt. This can realize the continuous operation of the main conveyor belt.

[0015] Furthermore, since the main conveyor belt is driven by pushing, the linear drive mechanism can withstand a greater load, thereby enabling the main conveyor belt to transport more goods.

[0016] Optionally, a switching hole is formed through the mounting seat, the switching hole penetrates the mounting seat in a vertical direction, the switching plate is plugged into and matched with the switching hole, and the switching plate is slidably connected to the inner side wall of the switching hole in a vertical direction.

[0017] By adopting the above technical solution, the switch hole on the mounting seat provides installation space for the switch plate, ensuring that the switch plate can slide in the vertical direction. In addition, the switch hole can guide the movement of the switch plate, which can improve the stability of the movement of the switch plate.

[0018] Optionally, the switching plate includes a hidden tube, a first plate and a second plate, the hidden tube is vertically arranged, the hidden tube is slidably connected to the mounting seat along the vertical direction, and the switching drive is connected to the hidden tube; the first plate is plug-fitted with the upper end of the hidden tube, the second plate is plug-fitted with the lower end of the hidden tube, and the first plate and the second plate are both slidably connected to the hidden tube along the vertical direction; a first drive member and a second drive member are arranged in the hidden tube, the driving directions of the first drive member and the second drive member are both arranged along the vertical direction, the first drive member is connected to the first plate, and the second drive member is connected to the second plate.

[0019] By adopting the above technical solution, the switching plate is arranged through the coordination of the hidden tube, the first plate, the second plate, the first driving member and the second driving member. Under the action of the first driving member and the second driving member, the first plate and the second plate can be independently raised and lowered, and then can be retracted into the hidden tube or extended from the hidden tube.

[0020] When the first plate and the second plate are both retracted into the hidden tube, the interference in the installation process of the switch plate can be reduced, and the installation of the switch connector is convenient. When the first plate and the second plate are both extended out of the hidden tube, the first plate, the second plate and the hidden tube cooperate to realize the function of the switch plate.

[0021] 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 the driving electromagnet is located below the first plate, the auxiliary magnetic plate is arranged on the lower side of the first plate, 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.

[0022] By adopting the above technical solution, the first driving member cooperates with the driving electromagnet, the reset spring and the auxiliary magnetic plate. When the driving electromagnet is energized, the driving electromagnet attracts the auxiliary magnetic plate. At this time, the first plate moves vertically downward until it is retracted into the hidden tube; when the driving electromagnet is de-energized, under the action of the reset spring, the first plate automatically resets upward until it extends out of the hidden tube, thereby realizing the function of the first driving member.

[0023] Optionally, a plurality of plug-in blocks are further provided on the inner side wall of the main conveyor belt, and plug-in grooves are provided on the upper and lower ends of the switching plate, and there is a plug-in groove that is plugged in and matched with the corresponding plug-in block in the vertical direction.

[0024] By adopting the above technical solution, the plug-in block and the plug-in slot are arranged in coordination, and when the switching plate rises or falls in the vertical direction, the plug-in block can be plugged and matched with the corresponding plug-in slot.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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 conveying of the main conveyor belt to ensure that the main conveyor belt can be rotated and conveyed on the fixed frame.

[0030] 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.

[0031] 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.

[0032] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application adopts a linear transmission method, replacing the existing chain transmission or belt transmission driving method. The linear transmission method can reduce the wear of the transmission components, improve the conveying accuracy of the main conveyor belt, and thus ensure the working efficiency and sorting accuracy of the sorting machine.

Similarly, when the linear drive 41 drives the mounting seat 531 in the reverse direction, the switching plate 532 falls, and the switching plate 532 contacts the corresponding push plate 52 in the second straight section 22. Under the drive of the linear drive 41, the switching plate 532 pushes the corresponding push plate 52 to move, thereby pushing the main conveyor belt 2 to move.

[0073] When the linear drive 41 drives the connection switching assembly 53 to reciprocate, the main conveyor belt 2 is driven under the action of the switching driving member 535 .

[0074] In this embodiment, refer to Fig. 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. The hidden tube 5321 is plugged into the switching hole 5311. The hidden tube 5321 slides with the inner wall of the switching hole 5311 along the vertical direction. The switching drive member 535 is connected to the hidden tube 5321.

[0075] Reference Fig. 9 The first plate 5322 is located at the upper end of the hidden tube 5321. The first plate 5322 is plugged into the hidden tube 5321. The first plate 5322 is slidably connected to the inner wall of the hidden tube 5321 along 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 along the vertical direction. The first driving member 533 is connected to the first plate 5322.

[0076] Reference Fig. 9 The second plate 5323 is located at the lower end of the hidden tube 5321, the second plate 5323 is plugged into the hidden tube 5321, the second plate 5323 is slidably connected to the inner wall of the hidden tube 5321 along 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 along the vertical direction, and the second driving member 534 is connected to the second plate 5323.

[0077] Under the action of the first driving member 533 and the second driving member 534, 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 the first plate 5322 and the second plate 5323 are both retracted into the hidden tube 5321, it is convenient to install the connection switch assembly 53. When the first plate 5322 and the second plate 5323 are both extended 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 switch plate 532.

[0078] Reference Fig. 9 , the first driving member 533 has the same structure as the second driving member 534, and this embodiment is described by taking the first driving member 533 as an example. 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 in the hidden tube 5321, and the driving electromagnet 5331 is located at the lower side of the first plate 5322 in the vertical direction, the driving electromagnet 5331 is spaced 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.

[0079] When the driving electromagnet 5331 is energized, the driving electromagnet 5331 attracts the auxiliary magnetic plate 5333, and the first plate 5322 moves vertically downward until it is retracted into the hidden tube 5321; when the driving electromagnet 5331 is de-energized, under the action of the reset spring 5332, the first plate 5322 automatically resets upward until it extends out of the hidden tube 5321, thereby realizing the function of the first driving member 533.

[0080] Reference Figure 7 and Figure 8 There are a plurality of linear drivers 41 , and there are a plurality of connection switching components 53 . The connection switching components 53 are arranged in a one-to-one correspondence with the linear drivers 41 , and the connection switching components 53 are arranged on the corresponding linear drivers 41 .

[0081] Reference Figure 7 and Figure 8 , a plurality of linear drivers 41 are sequentially arranged along the width direction of the main conveyor belt 2, and among the plurality of linear drivers 41, at least one linear driver 41 corresponding to the connection switching component 53 is connected to the first straight section 21 on the main conveyor belt 2, and at least one linear driver 41 corresponding to the connection switching component 53 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 subjected to force, which can improve the working stability of the main conveyor belt 2.

[0082] 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.

[0083] 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.

[0084] 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 .

[0085] 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.

[0086] 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.

[0087] Embodiment 3: A transmission assembly of a sorting machine, referring to Fig.10 The difference between this embodiment and the second embodiment is that: a plurality of plug-in blocks 521 are provided on each push plate 52, and the plurality of plug-in blocks 521 are arranged in sequence and spaced along the length direction of the push plate 52. The plug-in blocks 521 are slidably connected with the corresponding push plate 52 along the length direction of the push plate 52, and the plug-in blocks 521 and the corresponding push plate 52 are connected by bolts. When the bolts are loosened, it is convenient to slide and adjust the position of the plug-in blocks 521 along the length direction of the push plate 52, so that the plug-in blocks 521 and the corresponding switching plates 532 are aligned; after the plug-in blocks 521 and the corresponding switching plates 532 are aligned, the bolts are tightened to fix the plug-in blocks 521.

[0088] Reference Fig.10 and Fig.11 , the upper end of the first plate 5322 and the lower end of the second plate 5323 are both provided with plug-in grooves 5324, and the plug-in grooves 5324 are arranged corresponding to the plug-in blocks 521. When the switching drive member 535 drives the switching plate 532 to move vertically upward, the plug-in grooves 5324 on the first plate 5322 are plug-fitted with the corresponding plug-in blocks 521; when the switching drive member 535 drives the switching plate 532 to move vertically downward, the plug-in grooves 5324 on the second plate 5323 are plug-fitted with the corresponding plug-in blocks 521.

[0089] The implementation principle of the embodiment of the present application is: in the process of directly pushing the corresponding push plate 52 to move through the switching plate 532, when the main conveyor belt 2 is paused, the main conveyor belt 2 has the inertia to continue to move, which may cause problems with the positioning accuracy of the main conveyor belt 2. Through the cooperation between the plug slot 5324 and the plug block 521, when the main conveyor belt 2 is paused, the switching plate 532 fixes the plug block 521, which can prevent the main conveyor belt 2 from continuing to move due to inertia, thereby improving the positioning accuracy of the main conveyor belt 2.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
