Description

Technical Field

[0001] This utility model belongs to the field of logistics and conveying technology, and specifically relates to a sorting and conveying line. Background Technology

[0002] Weighing is required during the transportation and sorting process in logistics to avoid damage or compensation due to errors and to reduce disputes arising from weight disputes.

[0003] The existing sorting carts are equipped with connected belt conveyors and weighing devices. Goods are transported onto the belt conveyor, and the weighing device weighs the belt conveyor and the goods on it to achieve the weight. However, the weighing device is under pressure while supporting the belt conveyor for a long time, which can easily lead to elastic fatigue, strain gauge adhesion, or weld cracking, thus accelerating the aging of the weighing device and shortening the maintenance interval, requiring repeated shutdowns of the sorting conveyor line. Utility Model Content

[0004] The purpose of this invention is to provide a sorting and conveying line to solve one or more technical problems existing in the prior art.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: This utility model discloses a sorting and conveying line, comprising: The machine base is equipped with a drive mechanism and a travel track; The sorting trolley is connected to the output end of the drive mechanism, so that the sorting trolley moves in a circle along the travel track. The sorting trolley includes a belt conveyor, a weighing mechanism and a frame from top to bottom. The belt conveyor and the frame are detachably connected. The weighing mechanism is movably connected between the belt conveyor and the frame. The weighing mechanism is rotatably connected to cam followers at both ends perpendicular to the travel track. A lifting frame is connected to the machine base. The lifting frame is provided with a cam groove. The cam follower slides in the cam groove and raises and lowers the weighing mechanism by changing the height of the cam groove, so that the weighing mechanism rises and lifts the belt conveyor for weighing.

[0006] The present invention has at least the following beneficial effects: The weighing mechanism is connected to a cam follower, and the base is connected to a lifting frame with a cam groove. The cam follower slides within the cam groove. The output end of the drive mechanism drives all sorting trolleys to move in a circular motion along the travel track. Therefore, as the sorting trolleys move along the travel track, the cam follower rolls within the cam groove. When the height of the cam groove changes, the weighing mechanism connected to the cam follower can rise and fall with the cam groove, allowing the weighing mechanism to rise and lift the conveyor belt. At this time, the conveyor belt separates from the frame, thus allowing the belt and the goods on it to be weighed. The weighing mechanism connected to the cam follower can also descend with the cam groove, reconnecting the conveyor belt to the frame. The weighing mechanism no longer bears the load of the conveyor belt, placing it in a natural, unpressurized state. This avoids the weighing mechanism being constantly under pressure from the conveyor belt, extending the service life of the weighing mechanism, extending the maintenance interval of the sorting conveyor line, and improving the sorting efficiency of the sorting conveyor line.

[0007] Furthermore, the weighing mechanism automatically rises and falls with the height of the cam groove, eliminating the need for electrical equipment to drive the weighing mechanism's rise and fall, resulting in a simple structure and reduced costs.

[0008] As a further improvement to the above technical solution, the cam groove includes a weighing section, a conveying section and a connecting section. The connecting section has two sections, and its two ends are respectively connected to the weighing section and the conveying section. The weighing section is higher than the conveying section. The sorting trolley is configured to weigh, and the cam follower slides into the weighing section.

[0009] As a further improvement to the above technical solution, the frame is connected to a vertically extending guide member, the bottom of the belt conveyor is provided with a positioning hole, and the upper end of the guide member is embedded in the positioning hole.

[0010] As a further improvement to the above technical solution, the weighing mechanism includes a movable seat and a weighing sensor. The weighing sensor is connected to the upper end of the movable seat, and the movable seat is provided with a guide hole for the guide member to slide through.

[0011] As a further improvement to the above technical solution, the guide holes are provided in a plurality of them and are distributed in a rectangular array along the edge of the movable seat, and the guide member corresponds one to one with the guide hole.

[0012] As a further improvement to the above technical solution, the sorting trolley also includes an elastic element, the two ends of which are respectively connected to the weighing mechanism and the frame. The elastic element is sleeved on the outside of the guide member and is configured to be in a compressed state supporting the weighing mechanism.

[0013] As a further improvement to the above technical solution, the bottom of the belt conveyor is provided with a recessed positioning groove, and the sorting trolley is configured such that when it is in the weighing state, the weighing end of the weighing sensor is embedded in the positioning groove.

[0014] As a further improvement to the above technical solution, the bottom of the sorting trolley is rotatably connected to a traveling wheel, and the traveling track is provided with a limiting groove, in which the traveling wheel rolls.

[0015] As a further improvement to the above technical solution, the driving mechanism includes a drive motor, sprockets and a chain. The drive motor is connected to the machine base. Multiple sprockets are provided and rotatably connected to the machine base. The output end of the drive motor is drivenly connected to one of the sprockets. The chain meshes with multiple sprockets and connects to multiple sorting carts.

[0016] As a further improvement to the above technical solution, the sorting conveyor line also includes a scanning mechanism mounted above the base, with the scanning end of the scanning mechanism facing downwards and aligned vertically with the travel track. Attached Figure Description

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Reference Figures 1 to 5 The following are several embodiments of the sorting and conveying line of this utility model.

[0024] like Figures 1 to 5 As shown, the sorting conveyor line 100 of this utility model embodiment includes a base 200, a sorting trolley 400 and a lifting frame 500.

[0025] Understandably, the base 200 is equipped with a drive mechanism 300 and a travel track 210. Specifically, the drive mechanism 300 is fixedly connected to the base 200, and its output end is connected to a sorting cart 400 to drive the sorting cart 400 to move along the travel track 210. Multiple sorting carts 400 are provided and spaced apart; the output end of the drive mechanism 300 simultaneously drives multiple sorting carts 400 to move along the travel track 210. The travel track 210 consists of two straight sections and two semi-circular curves, forming a circular structure resembling a playground. The sorting carts 400 move cyclically along the travel track 210, continuously performing sorting operations.

[0026] It is understandable that the sorting trolley 400 includes, from top to bottom, a belt conveyor 410, a weighing mechanism 420, and a frame 430, such as... Figure 2 As shown. Specifically, the belt conveyor 410 and the frame 430 are detachably connected, allowing them to be separated. The weighing mechanism 420 is movably connected between the belt conveyor 410 and the frame 430, allowing the weighing mechanism 420 to move relative to the frame 430. Cam followers 421 are rotatably connected to both ends of the weighing mechanism 420, as shown... Figures 2 to 4 As shown, the two cam followers 421 are arranged in a direction perpendicular to the extension direction of the travel track 210, which facilitates the installation of lifting frames 500 for driving the weighing mechanism 420 on the inner and outer sides of the travel track 210.

[0027] It is understandable that the lifting frame 500 is connected and fixed to the base 200, and the lifting frame 500 is provided with a cam groove 510. The cam follower 421 is located in the cam groove 510. Figure 2 and Figure 3 As shown, when the sorting trolley 400 moves along the travel track 210 via the drive mechanism 300, the cam follower 421 slides along the cam groove 510. The change in the height of the cam groove 510 causes the weighing mechanism 420 to rise or fall relative to the frame 430. When the weighing mechanism 420 rises relative to the frame 430, it can lift the belt conveyor 410, separating it from the frame 430. The weighing mechanism 420 accurately weighs the belt conveyor 410 and the goods on it. Figure 3 and Figure 4 As shown. When the weighing mechanism 420 descends relative to the frame 430, the weighing mechanism 420 can lower the belt conveyor 410, reconnecting the belt conveyor 410 to the frame 430, as shown. Figure 2 As shown, the weighing mechanism 420 and the belt conveyor 410 are independent of each other, ensuring that the weighing mechanism 420 only carries the belt conveyor 410 and the goods on it during the upward weighing process.

[0028] This extends the service life of the weighing mechanism 420, eliminating the need for frequent replacement or maintenance of the weighing mechanism 420 and repeated interruptions of the sorting conveyor line 100 for replacement or maintenance, thereby increasing the working time of the sorting conveyor line 100 and improving sorting efficiency. Furthermore, the structure is simple; the cam follower 421 moves along the cam groove 510 via the movement of the sorting trolley 400 along the travel track 210, achieving automatic lifting and weighing of the weighing mechanism 420 during the transport of goods. After weighing, it automatically returns to an unpressurized state, eliminating the need for additional motors or pneumatic equipment to drive the lifting and lowering of the weighing mechanism 420.

[0029] It is understood that the extension direction of the lifting frame 500 is parallel to the extension direction of the traveling track 210. The lifting frame 500 includes an inner frame and an outer frame, and the cam groove 510 is respectively provided on the inner frame and the outer frame.

[0030] It is understandable that the cam groove 510 includes a weighing section 511, a conveying section 512, and a connecting section 513, such as... Figure 4 As shown. Specifically, there are two connecting sections 513, and the two ends of the connecting section 513 are respectively connected to the weighing section 511 and the conveying section 512. The sorting trolley 400 achieves lifting and lowering transition in the connecting section 513, and the weighing section 511 is higher than the conveying section 512.

[0031] It is understandable that when the output of the drive mechanism 300 moves the sorting trolley 400, causing the cam follower 421 to slide to the weighing section 511, the sorting trolley 400 is in a weighing state that lifts the belt conveyor 410, such as... Figure 4 As shown.

[0032] Understandably, when the output end of the drive mechanism 300 drives the sorting trolley 400 to move and causes the cam follower 421 to slide to the conveyor section 512, the sorting trolley 400 is in a stable conveying state. At this time, the belt conveyor 410 is connected to the frame 430 and supported by the frame 430.

[0033] It is understandable that when the output end of the drive mechanism 300 drives the sorting trolley 400 to move and causes the cam follower 421 to slide to the connecting section 513, the weighing mechanism 420 is in a rising or falling state.

[0034] Understandably, the frame 430 is connected to a vertically extending guide member 600, such as... Figures 2 to 4 As shown. The bottom of the belt conveyor 410 is provided with a positioning hole 411, as shown. Figure 5As shown, the upper end of the guide member 600 is used to fit into the positioning hole 411. The detachable connection between the frame 430 and the belt conveyor 410 is actually the engagement and disengagement of the guide member 600 and the belt conveyor 410. When the weighing mechanism 420 drives the belt conveyor 410 downward, the upper end of the guide member 600 is engaged in the positioning hole 411. At this time, the frame 430 and the belt conveyor 410 are stably connected, preventing the belt conveyor 410 and the frame 430 from separating during the conveying process of the sorting cart 400. When the weighing mechanism 420 drives the belt conveyor 410 upward, the upper end of the guide member 600 disengages from the positioning hole 411. At this time, the frame 430 and the belt conveyor 410 are separated, and the belt conveyor 410 is supported by the weighing mechanism 420.

[0035] It is understandable that the weighing mechanism 420 includes a movable seat 422 and a weighing sensor 423, such as Figure 2 As shown. Specifically, the load cell 423 is connected to the upper end of the movable seat 422. The movable seat 422 is provided with a guide hole for the guide member 600 to slide through. The guide hole extends in the vertical direction, so that the movable seat 422 can be accurately raised and lowered along the guide member 600, so as to avoid the load cell 423 from shifting and failing to stably support the belt conveyor 410.

[0036] It is understandable that the two cam followers 421 are rotatably connected to the movable seat 422.

[0037] Understandably, the guide holes are provided in multiple and arranged in a rectangular array along the edge of the movable seat 422. The guide member 600 corresponds to the guide hole one by one, which further ensures that the weighing mechanism 420 can be raised and lowered stably in the vertical direction, and can further strengthen the stability of the connection between the frame 430 and the belt conveyor 410 when they are connected.

[0038] In this embodiment, the horizontal cross-section of the movable seat 422 is square, and four guide holes are provided and respectively located at the four corners of the movable seat 422.

[0039] Understandably, the sorting cart 400 also includes a flexible component 610, such as... Figure 2 and Figure 3 As shown. Specifically, the elastic element 610 is connected to the weighing mechanism 420, that is, the upper end of the elastic element 610 is connected to the lower end of the movable seat 422, and the lower end of the elastic element 610 is connected to the frame 430, ensuring that the elastic element 610 extends and retracts in the vertical direction. The elastic element 610 is sleeved on the outside of the guide member 600, further ensuring the vertical extension and retraction of the elastic element 610. The elastic element 610 is in a compressed state supporting the weighing mechanism 420.

[0040] This avoids the situation where the two cam followers 421 are always supporting the weight of the weighing mechanism 420 and the belt conveyor 410 and the goods that it lifts up after being raised, which would cause the connection structure between the cam followers 421 and the weighing mechanism 420 to break easily, the cam followers 421 to wear out a lot, and the sliding friction between the cam followers 421 and the cam groove 510 to increase, thus exacerbating the load on the drive mechanism 300.

[0041] In some embodiments, when the sorting trolley 400 is in the conveying state, the elastic element 610 is in the compressed state, and when the sorting trolley 400 is in the weighing state, the elastic element 610 is in the stretched state, so that the two cam followers 421 support the weighing mechanism 420, the belt conveyor 410 and the goods only in the weighing state.

[0042] In other embodiments, the elastic element 610 is always in a compressed state, that is, when the sorting trolley 400 is in a conveying state or a weighing state, the elastic element 610 supports the weighing mechanism 420, the belt conveyor 410 and the goods, and the two cam followers 421 are only used to control the lifting and lowering of the weighing mechanism 420 along the cam groove 510.

[0043] In this embodiment, the elastic element 610 is a spring.

[0044] It is understandable that the bottom of the belt conveyor 410 is provided with a positioning groove 412, which is recessed upwards along the bottom of the belt conveyor 410, such as... Figure 5 As shown. The load cell 423 has an upward-facing weighing end. When the sorting trolley 400 is in weighing mode, the weighing end is embedded in the positioning groove 412, so that the weighing mechanism 420 and the belt conveyor 410 are positioned simultaneously during weighing, preventing the weighing mechanism 420 from shifting when lifting the belt conveyor 410, which would cause the belt conveyor 410 to fall off the weighing mechanism 420 and affect the sorting process. When the sorting trolley 400 switches to conveying mode, the downward-moving weighing end disengages from the positioning groove 412. At this time, the guide 600 is embedded in the positioning hole 411.

[0045] It is understandable that the four positioning holes 411 of the belt conveyor 410 are arranged in a rectangular array along the edge of the belt conveyor 410, and the positioning groove 412 is located in the middle of the rectangle formed by the four positioning holes 411, so that the guide member 600 is supported and positioned by the edge of the belt conveyor 410, and the weighing mechanism 420 is supported and positioned by the middle of the belt conveyor 410.

[0046] It is understandable that the four positioning holes 411 correspond vertically to the four guide holes.

[0047] It is understandable that the bottom of the sorting cart 400 is rotatably connected to the wheels 440, that is, the bottom of the frame 430 is rotatably connected to the wheels 440, such as... Figures 2 to 4As shown. Correspondingly, the travel track 210 is provided with a limiting groove, and the travel wheel 440 rolls along the limiting groove. The limiting groove is used to limit the circular movement of the sorting cart 400 and prevent the sorting cart 400 from deviating.

[0048] In this embodiment, the drive mechanism 300 includes a drive motor 310, a sprocket 320, and a chain 330, such as Figure 2 As shown. Specifically, the drive motor 310 is connected to the base 200, multiple sprockets 320 are provided and rotatably connected to the base 200, the output end of the drive motor 310 is connected to one of the sprockets 320 for transmission, and the chain 330 meshes with multiple sprockets 320 and is spaced to connect multiple sorting carts 400, that is, the chain 330 is connected to multiple cart frames 430.

[0049] Thus, when the drive motor 310 starts, the drive motor 310 drives the connected sprocket 320 to rotate relative to the machine base 200, thereby driving the chain 330 to move in a circular cycle, thereby enabling all sorting carts 400 to move simultaneously for sorting.

[0050] It is understandable that the scanning mechanism 700, mounted above the base 200, such as Figure 1 As shown, the scanning end of the scanning mechanism 700 is positioned downwards and aligned vertically with the travel track 210. When the sorting trolley 400 moves along the travel track 210, the scanning mechanism 700 can scan the express delivery documents of the goods on the conveyor belt 410, facilitating the sorting conveyor line 100 to obtain the transport information of the goods. Based on the transport information, when the sorting trolley 400 moves to the corresponding sorting box 800, the conveyor belt 410 starts to transport the goods into the sorting box 800, completing the sorting operation.

[0051] In this embodiment, the scanning mechanism 700 is an image acquisition device or a camera device.

[0052] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
