Description

Technical Field

[0001] This utility model relates to the field of AGV technology, and in particular to a special chassis for AGV bar drums. Background Technology

[0002] Sliver drums are specialized containers used in the textile industry for storing and transporting textile materials such as slivers and wool slivers. They are typically made of plastic or stainless steel and are widely used in cotton spinning equipment to ensure the efficient operation of the production process.

[0003] Currently, in textile factories, AGVs (Automated Guided Vehicles) are typically used for the precise, efficient, and automated transfer of slivers in large quantities. These vehicles are battery-powered, driverless transport vehicles equipped with electromagnetic and optical automatic guidance devices that allow them to travel along a prescribed path and provide safety protection and various transfer functions. However, existing slivers are often characterized by their large height and unstable center of gravity. Traditional AGVs typically place the slivers directly onto their chassis frame using lifting or hoisting equipment during transport. If they pass over uneven ground (such as ground seams), or if the operating speed is too high or the turning radius is too small, the slivers will wobble, affecting the stability of the transport and even posing a risk of tipping over. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a special chassis for AGV drums, which adopts a multi-point clamping and fixing method for the drums, thereby improving the overall stability during transportation and avoiding the risk of the drums shaking or even overturning due to uneven ground, excessive running speed, or too small turning radius.

[0006] To achieve the above objectives, the first aspect of this utility model provides a special chassis for AGV (Automated Guided Vehicle) drums, comprising: a base, a cover plate, a moving mechanism, a first clamping mechanism, and a second clamping mechanism. The base has an upper receiving compartment; the cover plate is disposed above the receiving compartment and connected to the base, and has multiple sliding grooves; the moving mechanism is disposed on the base; the first clamping mechanism includes a transmission component and a positioning component, wherein the transmission component is disposed inside the receiving compartment; the positioning component is disposed on the transmission component; and the second clamping mechanism is connected to the positioning component.

[0008] Specifically, the transmission assembly includes a rotating rod, a gear, a movable bracket, multiple movable plates, a second driving component, a connecting block, and a rack. The rotating rod is rotatably connected to the center of the bottom of the receiving compartment. The gear and the movable bracket are respectively sleeved on the outside of the rotating rod, with the movable bracket located above the gear. The multiple movable plates are rotatably connected to the movable bracket. The second driving component is installed at the bottom of the receiving compartment. The connecting block is connected to the output end of the second driving component. The rack is connected to the connecting block and meshes with the gear.

[0009] Specifically, the positioning component includes multiple sliders and multiple clamping blocks, wherein the multiple sliders are respectively connected to the corresponding movable plate and pass through the corresponding slide groove; the multiple clamping blocks are respectively connected to the upper end of the corresponding slider.

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The following describes an embodiment of the present invention with reference to the accompanying drawings: a special chassis for AGV bar drums.

[0017] like Figures 1-4 As shown in the figure, an AGV bar chassis according to an embodiment of the present invention may include: a base 1, a cover plate 2, a moving mechanism 3, a first clamping mechanism 4, and a second clamping mechanism 5.

[0018] The base 1 has a storage compartment 101 on its upper part.

[0019] The cover plate 2 is located on the upper part of the receiving compartment 101 and connected to the base 1. Multiple sliding grooves 201 are provided on the cover plate 2.

[0020] It should be noted that the container 101 and the cover plate 2 described in this embodiment are arranged with equal sides, and the slide grooves 201 are distributed in a ring array to facilitate adaptation to the bar barrel. The cover plate 2 and the base 1 are fixedly connected by bolts, so that the cover plate 2 can be removed to clean or replace parts inside the container 101.

[0021] The moving mechanism 3 is mounted on the base 1.

[0022] It should be noted that the moving mechanism 3 described in this embodiment adopts a two-wheel differential drive mode, which can rotate in place to achieve the steering function.

[0023] Additionally, it should be noted that the base 1 described in this embodiment is also equipped with a magnetic strip sensor (not shown in the figure), which enables the base 1 to move along the magnetic strip or predetermined magnetic nail track laid on the ground in conjunction with the moving mechanism 3, thereby realizing the automatic transportation function of the strip drum.

[0024] The first clamping mechanism 4 includes a transmission component 401 and a positioning component 402.

[0025] The transmission assembly 401 is disposed inside the receiving chamber 101, and the positioning assembly 402 is disposed on the transmission assembly 401.

[0026] It is understandable that the positioning component 402 can be tightened and clamped to fix the bottom of the bar drum by the transmission component 401, so as to prevent the bar drum from shifting when passing over uneven ground.

[0027] The second clamping mechanism 5 is connected to the positioning component 402.

[0028] Understandably, the second clamping mechanism 5 can clamp and fix the upper hoop of the bar to prevent the bar from shaking or overturning due to excessive running speed or small turning radius.

[0029] Specifically, when it is necessary to transfer the sliver drums in the textile factory, the worker first controls the device to move in front of the sliver drum, and then places the sliver drum in the middle of the upper part of the cover plate 2 by manual or mechanical handling.

[0030] Next, the transmission component 401 is activated to control and the positioning component 402 to tighten, so that the positioning component 402 clamps and fixes the bottom edge of the bar, so that the bar will not be displaced when the base 1 vibrates over uneven ground (such as ground seams or small obstacles).

[0031] Then, the second clamping mechanism 5 is activated to clamp and fix the protruding stainless steel hoop at the top of the drum, so that the drum will not shake or tip over when the base 1 runs too fast or the turning radius is too small, thus ensuring the overall stability of the drum during transportation.

[0032] Finally, the moving mechanism 3 is activated, causing the base 1 to automatically travel along the magnetic strips or predetermined magnetic nail tracks laid on the ground, transporting the barrel to the designated location.

[0033] In one embodiment of this utility model, such as Figure 1 and Figure 2As shown, the moving mechanism 3 includes two fixed plates 301, two drive wheels 302, two first drive components 303, multiple casters 304, and a power supply 305.

[0034] Two fixing plates 301 are respectively set in the middle of the lower two sides of the base 1, two drive wheels 302 are respectively rotatably connected to the corresponding fixing plates 301, two first drive components 303 are respectively installed in the lower part of the base 1, and their output ends are respectively connected to the corresponding drive wheels 302, multiple universal wheels 304 are respectively installed in the four corners of the lower part of the base 1, and the power supply 305 is set in the upper part of the base 1.

[0035] It should be noted that the first driving component 303 described in this embodiment can be a forward and reverse rotating motor, electrically connected to the power supply 305, and controlled by the PLC controller built into the AGV bar-specific chassis. When the two first driving components 303 rotate synchronously in the same direction, the two driving wheels 302 can be controlled to rotate synchronously in the same direction to make the base 1 move forward or backward. When the two first driving components 303 rotate synchronously in opposite directions, the base 1 can be controlled to rotate in place to adjust its direction when the two driving wheels 302 rotate synchronously in opposite directions, thereby realizing the function of flexible movement of the base 1.

[0036] In one embodiment of this utility model, such as Figure 3 As shown, the transmission assembly 401 includes a rotating rod 4011, a gear 4012, a movable bracket 4013, multiple movable plates 4014, a second driving component 4015, a connecting block 4016, and a rack 4017.

[0037] The rotating rod 4011 is rotatably connected to the bottom center of the receiving chamber 101. The gear 4012 and the movable bracket 4013 are respectively sleeved on the outside of the rotating rod 4011, and the movable bracket 4013 is located above the gear 4012. Multiple movable plates 4014 are rotatably connected to the movable bracket 4013. The second driving member 4015 is installed at the bottom of the receiving chamber 101. The connecting block 4016 is connected to the output end of the second driving member 4015. The rack 4017 is connected to the connecting block 4016 and meshes with the gear 4012.

[0038] It should be noted that a bearing is provided between the rotating rod 4011 and the bottom of the receiving chamber 101 as described in this embodiment to realize the rotation function of the rotating rod 4011.

[0039] It should be noted that the movable support 4013 described in this embodiment is arranged in a cross shape, and there are 4 movable plates 4014, each of which is hinged to one end of the movable support 4013.

[0040] Additionally, it should be noted that the second driving component 4015 described in this embodiment can be an electric actuator and is electrically connected to the power supply 305. The extension and retraction of the electric actuator can drive the rack 4017 to move back and forth, thereby driving the gear 4012 to rotate back and forth.

[0041] In one embodiment of this utility model, such as Figure 3 As shown, the positioning component 402 includes a plurality of sliders 4021 and a plurality of clamping blocks 4022.

[0042] Among them, multiple sliders 4021 are respectively connected to the corresponding movable plates 4014 and pass through the corresponding slide grooves 201, and multiple clamping blocks 4022 are respectively connected to the upper ends of the corresponding sliders 4021.

[0043] It should be noted that the clamping blocks 4022 described in this embodiment are arranged in a ring array, with their ends close to each other being rounded to avoid sharp edges from damaging the bar during clamping.

[0044] Specifically, when the bar is placed in the middle of the upper part of the cover plate 2, the second driving component 4015 is activated to drive the rack 4017 to move in conjunction with the connecting block 4016. The rack 4017 drives the gear 4012 to rotate, and the gear 4012 drives the rotating rod 4011 and the movable bracket 4013 to rotate. The movable bracket 4013, through the movable plate 4014, in conjunction with the slide groove 201 and the slider 4021, drives the four clamping blocks 4022 to move synchronously and retract, so that the clamping blocks 4022 clamp and fix the bottom of the bar.

[0045] In one embodiment of this utility model, such as Figure 4 As shown, the second clamping mechanism 5 includes multiple clamping plates 501 and multiple third driving members 502.

[0046] Among them, multiple clamping plates 501 are pivotally connected to corresponding clamping blocks 4022, and multiple third driving members 502 are pivotally connected at one end to corresponding clamping plates 501 and at the other end to corresponding clamping blocks 4022.

[0047] It should be noted that the third driving component 502 described in this embodiment can be an electric push rod and is electrically connected to the power supply 305. The extension and retraction of the third driving component 502 can drive the clamping plate 501 to rotate. The upper end of the clamping plate 501 is set in a rounded shape to avoid sharp edges from damaging the bar during the clamping process.

[0048] Specifically, after the clamping block 4022 has finished clamping the bottom of the bar, the third drive component 502 is activated to extend, thereby pushing the four clamping plates 501 to rotate and retract synchronously, clamping and fixing the protruding stainless steel hoop at the top of the bar, ensuring stability during transportation.

[0049] In summary, the AGV chassis for AGV drums of this invention uses a first clamping mechanism to clamp and fix the bottom of the drum, preventing displacement when the drum travels over uneven ground. The second clamping mechanism clamps and fixes the top of the drum, preventing swaying or overturning due to excessive speed or small turning radius, thereby improving the overall stability during transportation.
