Description

Technical Field

[0001] This utility model relates to the field of chain conveying devices, specifically a weighing chain conveying device that can be docked with an AGV vehicle. Background Technology

[0002] A weighing chain conveyor is a device used to weigh products conveyed by a chain. It combines both conveying and weighing functions. In the logistics industry, packages need to be weighed and sorted. Traditionally, when used with AGVs (Automated Guided Vehicles), the AGV can only transport goods to the end of the weighing chain conveyor, and then a push-pull mechanism moves the goods into the conveyor. This design not only requires an additional push-pull mechanism, increasing costs, but also limits the AGV's movement to the end of the weighing chain, resulting in a large space requirement.

[0003] Therefore, it is necessary to provide a weighing chain conveyor that can be docked with AGV vehicles. Utility Model Content

[0004] This utility model provides a weighing chain conveyor device that can be docked with AGV vehicles, which effectively solves the problem that existing weighing chain conveyors can only dock with the end of AGV vehicles, resulting in large space occupation and high cost.

[0005] The technical solution adopted in this utility model is: a weighing chain conveyor device that can be docked with an AGV vehicle, comprising a symmetrical left and right support frame, several weighing mechanisms, a left conveyor line disposed on the left support frame, a right conveyor line disposed on the right support frame, and a drive assembly for driving the left and right conveyor lines to move synchronously. The two ends of the left and right conveyor lines are the feed end and the discharge end, respectively. The several weighing mechanisms are symmetrically arranged below the left and right support frames. The drive assembly is located at the discharge end. An AGV inlet / outlet is disposed between the left and right support frames, and the AGV inlet / outlet is located at the feed end.

[0006] Furthermore, the weighing mechanism includes a base plate, a weighing sensor mounted on the base plate, a first plate mounted on the upper end of the weighing sensor by bolts, and several screws welded to the first plate, with two nuts threaded onto each screw.

[0007] Furthermore, the left and right legs have the same structure. The left leg includes a frame body and several support plates set on the frame body. Each support plate is provided with a mounting hole corresponding to a screw. The two nuts are located at the upper and lower ends of the support plate, respectively.

[0008] Furthermore, a right limiting mechanism is provided on the right side of the right leg. The right limiting mechanism includes a mounting frame, a crossbeam parallel to the right leg and mounted on the mounting frame, and a right baffle on the crossbeam. The upper end of the right baffle protrudes from the conveying surface of the right conveyor line.

[0009] Furthermore, the left side of the left leg is provided with a left limiting mechanism, which includes a left baffle, several brackets bolted to the left baffle, a guide rail fixedly connected to the left side of the left leg, and several connecting components connecting the brackets and the guide rail. The guide rail is provided with two sliding grooves parallel to the left leg. The connecting components include a slider, a washer, and a screw threadedly connected to the slider, which are slidably connected to the sliding groove. The bracket is provided with a first hole for engaging with the screw. One end of the screw passes through the first hole and is threadedly connected to the slider. The two sides of the washer abut against the left side of the bracket and the other end of the screw, respectively.

[0010] Furthermore, the left and right conveyor lines have the same structure. The left conveyor line includes a drive sprocket A and a driven sprocket A located at both ends of the left scaffold, and a roller chain A that is connected to the drive sprocket and the driven sprocket for transmission.

[0011] Furthermore, the drive assembly includes a connecting frame connecting the left and right legs, a mounting base on the connecting frame, a bearing seat on the mounting base, a ball bearing on the bearing seat, a drive shaft connected to the inner ring of the ball bearing, a driven sprocket B coaxially fixed on the drive shaft, a motor on the connecting frame, a driving sprocket B on the motor shaft, and a chain that is drively connected to the driving sprocket B and the driven sprocket B.

[0012] Furthermore, the discharge end is also equipped with a size detection mechanism, which includes a frame and several photoelectric sensors mounted on the frame.

[0013] The beneficial effects of this utility model are as follows: By setting up AGV inlets and outlets, the AGV trolley can be moved between the left and right legs, allowing the goods on the AGV trolley to land on the left and right conveyor lines. Compared with the traditional chain weighing device, which can only push the goods on the AGV trolley horizontally to the left and right conveyor lines, this application can be used with the AGV trolley in a more confined space and can also eliminate the need for a push-pull mechanism to move the goods in the AGV trolley, thus reducing costs.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 3As shown in the illustration, an embodiment of this application provides a weighing chain conveyor device that can dock with an AGV vehicle. Its structure includes a symmetrical left leg 1 and right leg 2, several weighing mechanisms 3, a left conveyor line 4 mounted on the left leg 1, a right conveyor line 5 mounted on the right leg 2, and a drive assembly 6 for synchronously driving the left and right conveyor lines 4 and 5. The left and right conveyor lines 4 and 5 are respectively a feed end and a discharge end. Several weighing mechanisms 3 are symmetrically arranged below the left and right legs 1 and 2. The drive assembly 6 is located at the discharge end. An AGV inlet / outlet 100 is provided between the left and right legs 1 and 2, and the AGV inlet / outlet 100 is located at the feed end.

[0023] It should be noted that the AGV must be a model with built-in lifting function.

[0024] In actual use, the weighing mechanism 3 weighs the left leg 1, right leg 2, left conveyor line 4, and right conveyor line 5 under no-load conditions, and the weighed weight is recorded as M0. An AGV trolley carrying goods enters from the AGV inlet / outlet 100 between the left leg 1 and right leg 2, so that the lower ends of both sides of the goods correspond to the upper ends of the left conveyor line 4 and right conveyor line 5, respectively. Then, the AGV trolley lowers the goods so that they are supported by the left conveyor line 4 and right conveyor line 5. After being supported, the weighing mechanism 3 records the weighed weight as M1, and the weight of the goods is M1 - M0. The AGV trolley then exits the device of this application along the AGV inlet / outlet 100. The goods are then transported to the next workstation by the left conveyor line 4 and right conveyor line 5.

[0025] In the above design, by setting the AGV inlet and outlet 100, the AGV trolley can be moved between the left foot 1 and the right foot 2, so that the goods on the AGV trolley can be lowered onto the left conveyor line 4 and the right conveyor line 5. Compared with the traditional chain 69 weighing device, which can only push the goods on the AGV trolley horizontally onto the left conveyor line 4 and the right conveyor line 5, this application can be used with the AGV trolley in a more confined space, and can also eliminate the need for a push-pull mechanism for moving the goods in the AGV trolley, thus reducing costs.

[0026] Specifically: such as Figure 2 As shown, the weighing mechanism 3 includes a base plate 31, a weighing sensor 32 mounted on the base plate 31, a first plate 33 mounted on the upper end of the weighing sensor 32 by bolts, and several screws 34 welded to the first plate 33. Each screw 34 is threaded with two nuts 35.

[0027] In actual use, weighing is performed using the load cell 32. The weighing mechanism 3 is installed on the ground via the base plate 31. The left leg 1 and right leg 2 are fixed in place by screws 34 and nuts 35.

[0028] In the above design, the structural design and specific implementation of the weighing mechanism 3 can effectively realize the installation of the weighing mechanism 3.

[0029] Specifically: such as Figure 2 As shown, the left leg 1 and the right leg 2 have the same structure. The left leg 1 includes a frame body 11 and several support plates 12 set on the frame body 11. Each support plate 12 is provided with a mounting hole corresponding to the screw 34. The two nuts 35 are located at the upper and lower ends of the support plate 12, respectively.

[0030] In actual use, one nut 35 of the weighing mechanism 3 is screwed onto the screw 34, the screw 34 of the weighing mechanism 3 passes through the mounting hole, and then another nut 35 is screwed onto the screw 34, so that the two nuts 35 abut against the upper and lower ends of the support plate 12 respectively.

[0031] In the above design, the structural design of the left leg 1 and the right leg 2 facilitates quick assembly with the weighing mechanism 3, and the height of the left leg 1 and the right leg 2 can be adjusted by adjusting the position of the two nuts 35.

[0032] Specifically: such as Figure 1 and Figure 4 As shown, a right limiting mechanism 7 is provided on the right side of the right leg 2. The right limiting mechanism 7 includes a mounting frame 71, a crossbeam 72 parallel to the right leg 2 and mounted on the mounting frame 71, and a right baffle 73 mounted on the crossbeam 72. The upper end of the right baffle 73 protrudes from the conveying surface of the right conveyor line 5. The bracket 82 is provided with a waist-shaped hole.

[0033] In actual use, the right limiting mechanism 7 is installed on an external fixing mechanism with screw holes (which can be the base plate 31 or the machine base). When the goods are supported by the left conveyor line 4 and the right conveyor line 5, the right baffle 73 limits the right side of the goods. When it is necessary to adjust the right limiting mechanism 7, the bracket 82 can be moved left and right and then the bracket 82 can be fixed to the external fixing mechanism by bolts passing through the waist-shaped holes.

[0034] In the above design, the structural design and specific implementation of the right limiting mechanism 7 can limit the right side of the goods and can adjust its position in the left and right directions, making it convenient for individual storage or to adapt to different goods.

[0035] Specifically: such as Figure 1 , Figure 2 and Figure 3As shown, a left limiting mechanism 8 is provided on the left side of the left leg 1. The left limiting mechanism 8 includes a left baffle 81, several brackets 82 bolted to the left baffle 81, a guide rail 83 fixedly connected to the left side of the left leg 1, and several connecting components 84 connecting the brackets 82 and the guide rails 83. The guide rail 83 is provided with two sliding grooves parallel to the left leg 1. The connecting components 84 include a slider 843 slidably connected to the sliding groove, a washer 842, and a screw 841 threadedly connected to the slider 843. The bracket 82 is provided with a first hole for cooperating with the screw 841. One end of the screw 841 passes through the first hole and is threadedly connected to the slider 843. The two sides of the washer 842 abut against the left side of the bracket 82 and the other end of the screw 841, respectively.

[0036] In actual use, the bracket 82 is fixed to the guide rail 83 by screw 841 and slider 843 threaded connection with clamping washer 842. When it is necessary to adjust the position of left baffle 81, loosen screw 841, slide connecting assembly 84 along slide groove, drive bracket 82 and left baffle 81 to move synchronously, and then tighten bolt. When goods are on the device of this application, left baffle 81 blocks the left side of the goods.

[0037] In the above design, the left limiting mechanism 8 is fixedly mounted on the left foot 1, which can limit the left side of the goods.

[0038] Specifically: such as Figure 5 As shown, the left conveyor line 4 and the right conveyor line 5 have the same structure. The left conveyor line 4 includes a drive sprocket A41 and a driven sprocket A42 set at both ends of the left support 1, and a roller chain A43 that is connected to the drive sprocket and the driven sprocket for transmission.

[0039] In actual use, the drive sprocket A41 rotates, and with the cooperation of the driven sprocket A42, the roller chain A43 is driven to achieve the conveying of goods.

[0040] In the above design, the structural design and specific implementation of the left conveyor line 4 and the right conveyor line 5 enable the transportation of goods.

[0041] Specifically: such as Figure 5 As shown, the drive assembly 6 includes a connecting frame 62 connecting the left leg 1 and the right leg 2, a mounting base 63 mounted on the connecting frame 62, a bearing seat 64 mounted on the mounting base 63, a ball bearing 65 mounted on the bearing seat 64, a drive shaft 66 connected to the inner ring of the ball bearing 65, a driven sprocket B67 coaxially fixedly mounted on the drive shaft 66, a motor 61 mounted on the connecting frame, a drive sprocket B68 mounted on the shaft of the motor 61, and a chain 69 that is drively connected to the drive sprocket B68 and the driven sprocket B67. The drive sprocket A41 is coaxially fixedly connected to the drive shaft 66.

[0042] In actual use, the motor 61 drives the drive sprocket B68 to rotate, which, with the help of the chain 69, drives the driven sprocket B67 to rotate. This causes the driven sprocket B67 to drive the transmission shaft 66 to rotate, and then the transmission shaft 66 drives the drive sprocket A41 to rotate.

[0043] In the above design, the structural design and specific implementation of the drive component 6 can achieve synchronous driving of the left conveyor line 4 and the right conveyor line 5.

[0044] Specifically: such as Figure 1 and Figure 6 As shown, the discharge end is also provided with a size detection mechanism 9, which includes a frame 91 and a plurality of photoelectric sensors 92 disposed on the frame 91.

[0045] In actual use, when the goods are sent out by the left conveyor line 4 and the right conveyor line 5, they pass through the frame 91. Several photoelectric sensors 92 in the frame 91 are evenly arranged along the height direction. The size of the goods is determined by the number of photoelectric sensors 92 triggered by the goods.

[0046] In the above design, the structural design and specific implementation of the size detection mechanism 9 can effectively determine the size of the goods.

[0047] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
