Description

Technical Field

[0001] This application relates to the field of automated conveying technology, and in particular to a material handling device. Background Technology

[0002] Due to the lack of feeding equipment to deliver parts to the engine assembly roller conveyor, most existing engine factories employ a layout where assembly workers stand outside the assembly roller conveyor, with materials placed behind them. This approach presents several problems: First, placing parts behind the assembly workers requires turning, walking, and bending over to retrieve them, impacting work efficiency. Second, medium to large engine parts are generally heavy, and bending over to retrieve them can easily lead to occupational diseases. Third, when there are many parts, there is insufficient space behind the assembly workers to accommodate all types of parts. Fourth, assembly workers working on one side of the material flow channel pose significant safety hazards, as illustrated by the circular feeding rack disclosed in authorization publication number CN212923268U, which exhibits the aforementioned issues.

[0003] In related technologies, patent CN215363139U discloses a multi-functional automatic material rack to solve the above problems. This multi-functional automatic material rack has a material feeding end at one end and a material picking end at the other. An inclined buffer channel and a return empty box channel are provided between the two ends, with the buffer channel located above the return empty box channel. This multi-functional automatic material rack can deliver parts directly in front of the assembler, eliminating unnecessary walking when picking up parts, reducing labor intensity, and improving production efficiency. The inclined placement of the buffer channel and the return empty box channel allows for buffering of the material boxes.

[0004] However, the aforementioned automatic material racks use cylinders in many places, such as buffer separators and empty box separators, as well as lifting mechanisms on both sides, resulting in high overall automation costs, large space occupation, and difficulty in implementation. Therefore, it is necessary to study and improve the above structure to provide a material handling device with greater practical value. Summary of the Invention

[0005] This application provides a material handling device to address the high automation costs and difficulties in automating material handling devices used in automotive parts assembly lines for handling materials with varying heights.

[0006] Regarding the issue of putting it into use.

[0007] This application provides a material handling device, including:

[0008] The material conveyor has a feeding end at one end and a picking end at the other end. An inclined upper material channel and a lower material channel are provided between the two ends, with the upper material channel located above the lower material channel.

[0009] The upper stop mechanism includes a stop section for blocking the material box and a release section extending to the lower material channel. The connection between the release section and the stop section is rotatably connected to the upper material channel. The material box on the lower material channel can trigger the release section to drive the stop section to rotate, so that the stop section releases the material box on the upper material channel.

[0010] In some embodiments, the upper material channel is provided with a sensing mechanism for sensing the passage of material boxes. When the sensing mechanism senses the passage of a material box on the upper material channel, it can release a stop section to block the next material box.

[0011] In some embodiments, the sensing mechanism includes a limiting section for pressing down the stop section and a sensing section for driving the limiting section to release the stop section, wherein the material box on the upper material channel can trigger the sensing section to drive the limiting section to release the stop section.

[0012] In some embodiments, the end of the sensing segment away from the limiting segment extends to the upper material channel, and an elastic element for resetting the sensing segment upward is provided between the sensing segment and the upper material channel;

[0013] The stop section is provided with a stop block on the side away from the release section that contacts the limiting section, and the upper material channel is provided with a limiting post located above the stop section.

[0014] In some embodiments, a lower stop mechanism is provided on the lower material channel. The lower stop mechanism includes a stop block for blocking the material box and a connecting rod rotatably connected to the lower material channel for driving the stop block to release the material box.

[0015] The connecting rod is provided with a limiting rod that abuts against the bottom surface of the lower material channel and is used to limit the connecting rod, and a counterweight rod for driving the connecting rod to flip downward. When the counterweight rod tilts upward with the connecting rod, it can stop the material box.

[0016] In some embodiments, the feeding end is provided with a bracket for carrying the material box and a lifting device for adjusting the height of the bracket. The lifting device can drive the bracket to rise and fall so that the bracket can connect to the upper or lower material channel.

[0017] In some embodiments, the bracket is hinged to the top of the lifting device via a hinge seat, and the tilt direction of the bracket is consistent with the tilt direction of the lower material channel. When the bracket is connected to the lower material channel, the upper material box of the lower material channel can slide down onto the bracket under the action of gravity.

[0018] The material discharge end is equipped with a stop bar. When the bracket is connected to the upper material channel, the stop bar can press the bracket that moves upward with the lifting device. The bracket can be flipped to be in the same direction of inclination as the upper material channel, so that the material box on the bracket can slide down to the upper material channel under the action of gravity.

[0019] In some embodiments, the lifting device is provided with a pressure plate extending above the limiting rod. The lifting device can drive the pressure plate to press down on the limiting rod, thereby driving the connecting rod to flip and drive the stop block to release the material box, while simultaneously driving the counterweight rod to lift up to block the next material box.

[0020] In some embodiments, the material receiving end is provided with a flipping mechanism, which includes a support and a swing frame rotatably connected to the support and used to carry the material box. The swing frame can connect the upper material channel or the lower material channel by rotation.

[0021] In some embodiments, the swing frame is provided with a counterweight for driving the swing frame to rotate, and a support rod located below the swing frame is rotatably connected to the swing frame. The support rod is used to support the swing frame so that the swing frame remains in communication with the upper material channel.

[0022] The bracket is equipped with a limit block and a handle located between the limit block and the support rod. The handle can be used to push the support rod to rotate around the swing frame so that the material box on the bracket can overcome the weight of the counterweight and drive the swing frame to flip to connect the lower material channel. The handle is equipped with a weight for driving the handle to reset.

[0023] The beneficial effects of the technical solution provided in this application include:

[0024] This application provides a material handling device. The material conveyor has a feeding end at one end and a picking end at the other end. An inclined upper material channel and a lower material channel are provided between the two ends. The upper material channel is located above the lower material channel. The upper stop mechanism includes a stop section for blocking the material box and a release section extending to the lower material channel. The connection between the release section and the stop section is rotatably connected to the upper material channel. The material box on the lower material channel can trigger the release section to drive the stop section to rotate, so that the stop section releases the material box on the upper material channel.

[0025] Therefore, the upper material channel is a material channel for buffer boxes, and the lower material channel is a material channel for empty boxes. The upper stop mechanism installed on the upper material channel can stop the boxes, thereby achieving buffering of the boxes. When the assembler takes a part from the box at the picking end, when the empty box slides back to the discharging end along the inclined lower material channel, it can push the release section to rotate upward, thereby causing the stop section to disengage from the box on the upper material channel. After the stop section releases a box on the upper material channel, the release section rotates downward to reset due to gravity, thereby stopping the subsequent boxes on the upper material channel. Thus, when a box returns to the lower material channel, a corresponding box is released from the upper material channel. The device of this application cleverly uses the return of the box in the lower material channel to trigger the release of the box in the upper material channel, realizing automatic material discharging. For automotive parts assembly lines with high and low drop handling, the automation application is low-cost and easy to implement. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] This application provides a material handling device that can solve the problem in related technologies that the matching feeding device for automotive parts assembly lines with high and low drop handling is costly to automate and not easy to put into use.

[0038] See Figures 1 to 6 As shown, this application provides a material handling device, including:

[0039] The material conveyor 1 has a material feeding end at one end and a material picking end at the other end. An inclined upper material channel 2 and a lower material channel 3 are provided between the two ends, with the upper material channel 2 located above the lower material channel 3.

[0040] The upper stop mechanism 4 includes a stop section 41 for blocking the material box 10 and a release section 42 extending to the lower material channel 3. The connection between the release section 42 and the stop section 41 is rotatably connected to the upper material channel 2. The material box 10 on the lower material channel 3 can trigger the release section 42 to drive the stop section 41 to rotate, so that the stop section 41 releases the material box 10 on the upper material channel 2.

[0041] The material handling device of this application embodiment has an upper material channel 2 and a lower material channel 3, corresponding to... Figure 1 The left end is the material picking end, the right end is the material discharging end, the upper material channel 2 is the material channel for the buffer material box 10, and the lower material channel 3 is the material channel for the empty box. The material box 10 is used to store parts. The material box 10 can slide along the upper material channel 2 and the lower material channel 3 under the action of gravity. When in use, the assembler takes the parts from the material box 10 at the picking end, and the empty material box 10 slides back to the discharging end along the inclined lower material channel 3.

[0042] Specifically, when an empty material box 10 slides back to the discharge end along the inclined lower material channel 3, it can push the release section 42 to rotate upward, thereby causing the stop block 43 of the stop section 41 to disengage from the material box 10 on the upper material channel 2. After the stop section 41 releases one material box 10 on the upper material channel 2, the release section 42 rotates downward to reset due to gravity, thereby stopping the subsequent material box 10 on the upper material channel 2. Figure 2 Thus, when the lower material channel 3 returns a material box 10, the upper material channel 2 releases a corresponding material box 10. The device of this application cleverly utilizes the return of the material box 10 of the lower material channel 3 to trigger the release of the material box 10 of the upper material channel, thereby realizing automatic material feeding. For automotive parts assembly lines with high and low drop handling, the automation application is low-cost and easy to put into use.

[0043] In some alternative embodiments: see Figures 1 to 6As shown, this application embodiment provides a material handling device. The upper material channel 2 of the material handling device is provided with a sensing mechanism 5 for sensing the passage of the material box 10. When the sensing mechanism 5 senses that the material box 10 passes through the upper material channel 2, it can release the stop section 41 so that the stop section 41 blocks the next material box 10.

[0044] The sensing mechanism 5 includes a limiting section 51 for pressing down the stop section 41 and a sensing section 52 for driving the limiting section 51 to release the stop section 41. The material box 10 on the upper material channel 2 can trigger the sensing section 52 so that the sensing section 52 drives the limiting section 51 to release the stop section 41.

[0045] The sensing mechanism 5 in this embodiment includes a limiting section 51 and a sensing section 52. The connection between the limiting section 51 and the sensing section 52 is rotatably connected to the upper material channel 2. The end of the limiting section 51 away from the sensing section 52 abuts against the top of the stop block 43 of the stop section 41. The limiting section 51 and the sensing section 52 form a seesaw. When the material box 10 on the upper material channel 2 slides past the sensing section 52, the material box 10 presses down on the sensing section 52. According to the lever principle, the limiting section 51 tilts upward, thereby releasing the stop block 43 of the stop section 41. The release section 42 rotates downward and resets due to gravity, thereby stopping the material box 10 on the upper material channel 2. Figure 2 .

[0046] In this example, by setting the sensing mechanism 5 to link with the upper material channel 2, it is ensured that when the material box 10 on the upper material channel 2 slides past the sensing section 52, the blocking block 43 can be released quickly upwards, ensuring that the next material box 10 on the upper material channel 2 is quickly stopped. Specifically, when multiple material boxes 10 are put into the feeding end, the first material box 10 can pass through the sensing mechanism 5, and the subsequent material boxes 10 are buffered on the upper material channel 2. At the same time, after the first material box 10 is removed by the assembler, an empty material box 10 can be obtained. The empty material box 10 is transferred to the lower material channel 3 to return, which is used to trigger the release section 42 of the upper blocking mechanism 4 to make the blocking block 43 release another material box 10. After the empty material box 10 returns to the feeding end, a part can be put in and transferred to the upper material channel 2 for buffering, thereby ensuring the circulation of the material boxes 10 of the material handling device.

[0047] In some alternative embodiments: see Figure 2 and Figure 3 As shown, this application embodiment provides a material handling device. The sensing section 52 of the material handling device extends to the upper material channel 2 at one end away from the limiting section 51. An elastic member 53 for resetting the sensing section 52 upward is provided between the sensing section 52 and the upper material channel 2.

[0048] A stop block 43 that contacts the limiting section 51 is provided on the side of the stop section 41 away from the release section 42, and a limiting post 44 located above the stop section 41 is provided on the upper material channel 2.

[0049] In this embodiment, the sensing segment 52 extends upward to the upper material channel 2 from the end away from the limiting segment 51. When a material box 10 passes through the upper material channel 2, it can squeeze the raised end of the sensing segment 52, thereby causing the limiting segment 51 to rise and release the stop block 43. The release segment 42 rotates downward due to gravity, causing the stop segment 41 to rise upward and abut against the limiting post 44. At the same time, the stop block 43 of the stop segment 41 stops the subsequent material box 10, ensuring that one material box 10 is released at a time. In addition, an elastic member 53 is connected between the sensing segment 52 and the upper material channel 2. The elastic member 53 can be an elastic ring, which can assist the sensing segment 52 in resetting.

[0050] It should be noted that, Figure 2 In the state shown, when an empty material box 10 in the lower material channel 3 triggers the release section 42, the release section 42 can tilt upwards, causing the stop block 43 to reset below the limit section 51, corresponding to... Figure 3 As shown in the state, when the material box 10 on the upper material channel 2 can smoothly slide through the sensing section 52 under the action of gravity after being released, the sensing section 52 can be triggered to release the blocking block 43 to quickly stop the next material box 10, so as to ensure that the upper material channel 2 can buffer the material box 10 while releasing one material box 10 at a time.

[0051] In some alternative embodiments: see Figure 1 , Figure 5 and Figure 6 As shown, this application embodiment provides a material handling device. The lower material channel 3 of the material handling device is provided with a lower stop mechanism 6. The lower stop mechanism 6 includes a stop block 61 for blocking the material box 10, and a connecting rod 62 rotatably connected to the lower material channel 3 and used to drive the stop block 61 to release the material box 10.

[0052] The connecting rod 62 is provided with a limiting rod 63 that abuts against the bottom surface of the lower material channel 3 and is used to limit the connecting rod 62, and a counterweight rod 64 for driving the connecting rod 62 to flip downward. When the counterweight rod 64 tilts upward with the connecting rod 62, it can stop the material box 10.

[0053] The lower stop mechanism 6 of this application embodiment is provided with a connecting rod 62. A stop block 61 is fixed near the right end of the connecting rod 62. The initial position of the stop block 61 is higher than the bearing surface of the material box 10 of the lower material channel 3. When an empty material box 10 on the lower material channel 3 slides back to the right end under the action of gravity, it can be blocked by the stop block 61. When it is necessary to release the empty material box 10, the connecting rod 62 can drive the stop block 61 to the lower material box 10.

[0054] Furthermore, a limiting rod 63 is fixed near the right end of the connecting rod 62, and a counterweight rod 64 is fixed to the left end of the connecting rod 62. Under the action of gravity, the limiting rod 63 at the right end of the connecting rod 62 abuts against the bottom surface of the lower material channel 3, thereby ensuring that the stop block 61 stays in the initial position to stop the material box 10.

[0055] When an empty material box 10 needs to be released, the limiting rod 63 is pressed down, and the limiting rod 63 drives the right end of the connecting rod 62 to rotate downward, so that the stop block 61 at the right end of the connecting rod 62 disengages from the material box 10. At the same time, the counterweight rod 64 at the left end of the connecting rod 62 tilts upward. By reasonably setting the length of the connecting rod 62, it can be ensured that the connecting rod 62 drives the counterweight rod 64 to tilt upward to stop the subsequent empty material boxes 10, thereby ensuring that the lower material channel 3 can buffer the material boxes 10 while releasing an empty material box 10 at a time.

[0056] In some alternative embodiments: see Figure 1 , Figure 5 and Figure 6 As shown, this application embodiment provides a material handling device. The material handling device is provided with a bracket 7 for carrying the material box 10 at the discharge end, and a lifting device 8 for adjusting the height of the bracket 7. The lifting device 8 can drive the bracket 7 to rise and fall, so that the bracket 7 can connect to the upper material channel 2 or the lower material channel 3.

[0057] In this embodiment, the material conveyor 1 is provided with a lifting device 8 at its right end. A bracket 7 is installed at the lifting end of the lifting device 8. A material box 10 can be placed in the bracket 7. The lifting device 8 can lift the bracket 7 and the material box 10 to the height of the upper material channel 2, so as to facilitate the release of the material box 10 containing parts from the upper material channel 2. At the same time, the lifting device 8 can lower the bracket 7 to the height of the lower material channel 3, so as to facilitate the bracket 7 to receive the empty material box 10 returning from the lower material channel 3.

[0058] In some alternative embodiments: see Figure 1 , Figure 5 and Figure 6 As shown, this application embodiment provides a material handling device. The bracket 7 of the material handling device is hinged to the top of the lifting device 8 through the hinge seat 81. The tilting direction of the bracket 7 is consistent with the tilting direction of the lower material channel 3. When the bracket 7 is connected to the lower material channel 3, the upper material box 10 of the lower material channel 3 can slide down onto the bracket 7 under the action of gravity.

[0059] The material discharge end is equipped with a stop bar 82. When the bracket 7 is connected to the upper material channel 2, the stop bar 82 can press the bracket 7 which moves upward with the lifting device 8. The bracket 7 can be flipped to be in the same direction as the upper material channel 2, so that the material box 10 on the bracket 7 can slide down to the upper material channel 2 under the action of gravity.

[0060] In this embodiment, a stop bar 82 is fixedly installed at the right end of the upper material channel 2. The bracket 7 is hinged to the top of the lifting device 8 through a hinge seat 81. The bracket 7 and the hinge seat 81 form a seesaw structure. An opening for the material box 10 to enter and exit is provided at the left end of the bracket 7. A slide for carrying the material box 10 is installed on the bracket 7. When the lifting device 8 drives the bracket 7 and the material box 10 to rise and connect with the upper material channel 2, during the rising process, the bracket 7 approaches the stop bar 82 and abuts against the stop bar 82. The left end of the bracket 7 is pressed by the stop bar 82, and the left end of the bracket 7 flips downward. When the bracket 7 is connected with the upper material channel 2, the tilt direction of the bracket 7 is consistent with the upper material channel 2. The material box 10 containing the parts can slide off the bracket 7 and enter the upper material channel 2 under the action of gravity.

[0061] It should be noted that in this example, the bracket 7 is lighter on the left and heavier on the right. When the bracket 7 needs to receive an empty material box 10, the lifting device 8 drives the bracket 7 to descend and connect with the lower material channel 3. During the descent, the bracket 7 disengages from the stop bar 82. Since the bracket 7 is lighter on the left and heavier on the right, the right end of the bracket 7 flips downward, so that when the bracket 7 is connected with the lower material channel 3, the tilt direction of the bracket 7 is consistent with that of the lower material channel 3. The lower material channel 3 can slide into the bracket 7 under the action of gravity and stay inside the bracket 7, which is convenient for subsequent parts to be placed and then lifted together with the bracket 7.

[0062] In some alternative embodiments: see Figure 5 and Figure 6 As shown, this application embodiment provides a material handling device. The lifting device 8 of the material handling device is provided with a pressure plate 83 extending above the limiting rod 63. The lifting device 8 can drive the pressure plate 83 to press down the limiting rod 63, thereby driving the connecting rod 62 to flip and drive the stop block 61 to release the material box 10, while driving the counterweight rod 64 to lift up to block the next material box 10.

[0063] In this embodiment, a pressure plate 83 is fixedly installed on the lifting device 8 above the limiting rod 63. When the bracket 7 needs to receive an empty material box 10, the lifting device 8 drives the bracket 7 to descend and connect with the lower material channel 3. During the descent, the pressure plate 83 approaches and abuts against the limiting rod 63. The pressure plate 83 drives the limiting rod 63 to move down, so that when the bracket 7 is connected with the upper material channel 2, the pressure plate 83 can drive the limiting rod 63 to move down and cause the right end of the connecting rod 62 to flip downward. The connecting rod 62 drives the stop block 61 to disengage from the material box 10. At the same time, since the left side of the bracket 7 is lighter than the right side, the right end of the bracket 7 flips downward. The tilt direction of the bracket 7 is consistent with the lower material channel 3. The lower material channel 3 can automatically slide into the bracket 7 under the action of gravity and stay in the bracket 7.

[0064] In some alternative embodiments: see Figure 1 , Figure 4 and Figure 6As shown, this application embodiment provides a material handling device. The material handling device has a flipping mechanism 9 at the picking end. The flipping mechanism 9 includes a support 91 and a swing frame 92 rotatably connected to the support 91 and used to carry the material box 10. The swing frame 92 can connect to the upper material channel 2 or the lower material channel 3 by rotating.

[0065] In this embodiment, the left end of the feeding rack 1 is equipped with a flipping mechanism 9. The flipping mechanism 9 includes a bracket 91 fixedly installed with the feeding rack 1. A swing frame 92 is rotatably connected inside the bracket 91. In this example, a slide rail rotatably connected to the bracket 91 is installed on the top surface of the swing frame 92. By rotating the swing frame 92, the slide rail can be connected to the upper material channel 2, which is convenient for receiving the material box 10 sliding down from the upper material channel 2. After the assembler takes out the parts in the material box 10, by rotating the swing frame 92 in the opposite direction, the slide rail can be connected to the lower material channel 3. The empty material box 10 on the slide rail can automatically slide into the lower material channel 3 under the action of gravity.

[0066] In some alternative embodiments: see Figures 1 to 6 As shown, this application embodiment provides a material handling device. The swing frame 92 of the material handling device is provided with a counterweight 93 for driving the swing frame 92 to rotate. A support rod 94 located below the swing frame 92 is rotatably connected to the swing frame 92. The support rod 94 is used to support the swing frame 92 so that the swing frame 92 is kept in communication with the upper material channel 2.

[0067] The bracket 91 is provided with a limit block 95 and a handle 96 located between the limit block 95 and the support rod 94. The handle 96 can push the support rod 94 to rotate around the swing frame 92 so that the material box 10 on the bracket 7 can overcome the weight of the counterweight block 93 and drive the swing frame 92 to flip to connect the lower material channel 3. The handle 96 is provided with a weight 97 for driving the handle 96 to reset.

[0068] In this embodiment, a counterweight 93 is fixedly installed on the left end of the swing frame 92 extending from the support 91. Under the action of the counterweight 93, the right end of the swing frame 92 is kept tilted up, so that the slide on the swing frame 92 is connected to the upper material channel 2. At the same time, a support rod 94 located below the swing frame 92 is rotatably connected to the swing frame 92. The support rod 94 abuts against the support 91, ensuring that after the material box 10 with parts in the upper material channel 2 slides into the slide on the swing frame 92, the swing frame 92 can remain upright, making it convenient for assembly workers to take out the parts in the material box 10. When it is necessary to release an empty material box 10 to the lower material channel 3, by rotating the support rod 94 to the left, the swing frame 92 loses its support, so that the empty material box 10 can drive the right end of the swing frame 92 to flip down and connect with the lower material channel 3 under the action of gravity, thereby making it convenient for the empty material box 10 to slide into the lower material channel 3 under the action of gravity.

[0069] In this example, a limiting block 95 located on the right side of the support rod 94 is fixedly installed on the bracket 91. A handle 96, which is rotatably connected to the bracket 91, is installed between the limiting block 95 and the support rod 94. The bottom end of the support rod 94 is slidably connected to the bracket 91. By rotating the handle 96, the support rod 94 can be pushed to rotate to the left, so that the empty material box 10 can drive the right end of the swing frame 92 to flip downward and connect with the lower material channel 3 under the action of gravity. After the empty material box 10 slides into the lower material channel 3 under the action of gravity, the right end of the swing frame 92 can automatically flip upward and reset under the action of the counterweight block 93, and at the same time, the support rod 94 swings back to its original position. Meanwhile, the weight 97 can pull the handle 96 under the action of gravity, so that the handle 96 resets, thereby keeping the slide on the swing frame 92 connected with the upper material channel 2. The device of this application eliminates the number of times personnel have to walk while carrying heavy loads (including going up and down stairs), and the overall frame of the device can be spliced ​​with lean pipes, resulting in low device cost.
