Description

Technical Field

[0001] The invention belongs to the field of online disassembly and assembly of covers of coal sample barrels, and in particular relates to an online disassembly and assembly device of covers of coal sample barrels. Background Art

[0002] During the coal sampling and sample preparation process, coal samples usually need to be sealed and stored in barrels to ensure the integrity and quality of the samples, and then transferred to the next process for processing. In this transfer process, a conveyor line is usually used to improve work efficiency. However, in the coal sample preparation stage, sample processing is not just a simple transfer, and often requires a series of complex operations such as merging and mixing multiple coal samples. At this time, removing and installing the lid becomes an indispensable step, and these operations traditionally require the cooperation of a robotic arm to complete. However, because the robotic arm is relatively complex and time-consuming when handling the actions of removing and installing the lid, the overall efficiency of the production line is seriously affected.

[0003] The shortcomings of the prior art are manifested in many aspects:

[0004] The existing cover removal and installation device is designed as a single process equipment, which means that it can only perform one operation at a time and cannot handle the removal or installation of multiple coal sample barrels at the same time. This intermittent operation mode not only slows down the production rhythm, but also increases the waiting time for sample processing, and the overall efficiency is obviously low.

[0005] The existing device must rely on a robotic arm to remove and install the cover. Although the robotic arm can play a role in high-precision tasks, this conventional removal and installation of the cover greatly reduces its work efficiency. The robotic arm has a slow operating speed, and frequent use makes it unable to efficiently handle other more complex tasks, which greatly limits the overall efficiency of the production line and the function of the robotic arm.

[0006] The current cap removal and installation device fails to form a seamless connection with the entire production line and usually exists as an independent device. This independence causes the cap removal and installation operation to be out of touch with the automated production process of the conveyor line, making it unsuitable for modern assembly line operations and hindering the continuity and automation of the production line. This not only increases the complexity of the operation, but also creates a bottleneck for the production line's capacity.

[0007] In view of this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] See also Figure 1-5 As shown, in this embodiment, a coal sample barrel online cap disassembly and assembly device is provided, comprising a bracket 3, wherein a cap disassembly conveyor line 1 and a cap assembly conveyor line 2 are arranged in the bracket 3, wherein the length of the cap disassembly conveyor line 1 is shorter than the length of the cap assembly conveyor line 2;

[0037] A first clamping mechanism 9 and a barrel stop assembly 8 are connected to one side of the cover removal conveyor line 1. The first clamping mechanism 9 is used to clamp the coal sample barrel during the cover removal process, and the barrel stop assembly 8 is used to control and position the coal sample barrel.

[0038] The barrel retaining assembly 8 is located on the right side of the first clamping mechanism 9, and a second clamping mechanism 10 is connected to one side of the capping conveying line 2 to fix the empty coal sample barrel during the capping operation;

[0039] A sliding mechanism is arranged above the bracket 3, and a barrel cover clamping mechanism 6 is arranged at the telescopic end of the sliding mechanism, which is responsible for grabbing and releasing the barrel cover when removing and installing the cover;

[0040] A barrel cover buffer rack 7 is fixedly connected to the edge below the bracket 3 for temporarily storing the removed barrel covers so that they can be quickly retrieved during the cover installation operation.

[0041] By embedding the cover disassembly and installation device into the transmission line of the coal sample barrel, the present invention realizes seamless integration of the device with the transmission line, so that the cover removal and installation operations can be carried out continuously on the same production line, avoiding the interruption and waiting in traditional operations, and greatly improving the overall work efficiency. The process of removing and installing the cover no longer relies on independent operating units, but is integrated into the assembly line system, so that each link can be smoothly connected, significantly reducing time waste. In addition, with the automation of the cover removal and installation process, the collaborative robot arm no longer needs to participate in the tedious cover removal and installation operations, which frees the robot arm so that it can be put into more complex or critical tasks, such as handling, loading or other high-precision operations, further improving the work efficiency of the robot arm. Ultimately, the introduction of this device not only optimizes the entire assembly line operation process of coal sample barrel transmission, but also makes the production line more intelligent and automated, the operation smoother, and the overall production system becomes more comprehensive and practical, effectively improving production capacity and equipment utilization.

[0042] According to the device for online disassembly and assembly of the cover of a coal sample barrel according to claim 1, it is characterized in that the sliding mechanism includes a horizontal moving module 4 located above the bracket 3, a vertical moving module 5 is arranged above the horizontal moving module 4, the telescopic end of the vertical moving module 5 passes through the bracket 3 and the barrel cover clamping mechanism 6 to connect, and a through slot for the telescopic end of the vertical moving module 5 to slide is provided between the upper and lower parts of the bracket 3. The sliding mechanism enables the barrel cover clamping mechanism 6 to move flexibly in the horizontal and vertical directions through the combination of the horizontal moving module 4 and the vertical moving module 5, thereby achieving precise positioning. This multi-dimensional mobility ensures that the device can efficiently complete the operations of disassembly and assembly of the cover, and adapt to coal sample barrels of different heights and positions. In addition, the telescopic end of the vertical moving module 5 passes through the through slot design between the bracket 3 and the barrel cover clamping mechanism 6, making the entire device more compact in space, and also facilitating the barrel cover clamping mechanism 6 to freely extend and retract when disassembling and assembling the cover. The opening of the through slot effectively ensures the smooth operation of the vertical moving module 5 when it moves up and down, avoids friction or jamming caused by space limitations, and further improves work efficiency and equipment stability. Through this structural design, the operation of the entire device is smoother, more accurate, and more automated, effectively improving the overall efficiency of the production line.

[0043] According to the device for disassembling and installing the cover of a coal sample barrel online according to claim 1, it is characterized in that the barrel cover cache rack 7 is a U-shaped frame structure, and a plurality of placement slots for placing the barrel cover in the barrel cover cache rack 7 are provided on one side of the barrel cover cache rack 7, and the space inside the barrel cover cache rack 7 is connected to the through slot. The U-shaped frame structure can provide a stable and concise storage space, ensuring that the removed barrel cover can be placed in a specific position in an orderly manner, reducing the risk of the barrel cover moving or slipping during operation. Secondly, the placement slot on one side of the barrel cover cache rack 7 provides a precise positioning function for the storage and access of the barrel cover, so that each barrel cover can be placed independently, which is convenient for subsequent cover installation operations and improves the efficiency and accuracy of removing the cover. In addition, the space inside the cache rack is connected to the through slot. This design enables the barrel cover clamping mechanism 6 to directly extend from the through slot into the cache rack, quickly and smoothly grab or place the barrel cover, and reduce unnecessary moving paths and complex operation steps. This structure simplifies the entire operation process, not only improves the automation level of the equipment, but also reduces the operation time, and significantly improves the overall production efficiency of the assembly line.

[0044] According to claim 1, a coal sample barrel online disassembly and assembly device is characterized in that the first clamping mechanism 9 includes a first cylinder bracket 92 fixed on one side of the disassembly conveyor line 1, the first cylinder bracket 92 is located at the end of the disassembly conveyor line 1, a finger cylinder 91 is connected above the first cylinder bracket 92, both output ends of the finger cylinder 91 are fixedly connected to a connection block 96, and the opposite ends of the two connection blocks 96 are respectively fixedly connected to a left clamping jaw 94 and a right clamping jaw 93, a first photoelectric sensor 95 is provided on one side of the finger cylinder 91, and the opposite sides of the ends of the left clamping jaw 94 and the right clamping jaw 93 are fixedly connected to an arc clamping plate 97. The first cylinder bracket 92 in the first clamping mechanism 9 is fixed on one side of the disassembly conveyor line 1 and is located at the end position. Such a layout ensures that the coal sample barrel can be clamped quickly and accurately when it reaches the specified position, and optimizes the positioning efficiency during the operation. The two output ends of the finger cylinder 91 are respectively connected to the left and right clamping jaws 93 through the connection block 96, so that the clamping action is more stable and reliable. The clamping claws can clamp the coal sample barrel from both sides at the same time, providing strong support to prevent the coal sample barrel from moving or tilting during the process of removing the cover.

[0045] In addition, a photoelectric sensor is provided on one side of the finger cylinder 91. This design adds an intelligent monitoring function. The photoelectric sensor can detect the position of the coal sample barrel in real time, ensure that the clamping operation is performed at the right time, and avoid misoperation caused by misalignment of the coal sample barrel. This sensor can also further improve the automation and operation accuracy of the system and reduce human intervention.

[0046] The arc-shaped clamping plates 97 at the ends of the left clamping jaw 94 and the right clamping jaw 93 further enhance the stability of the clamping. The arc-shaped structure can better fit the shape of the coal sample barrel, so that the clamping force is evenly distributed, effectively preventing the barrel from being damaged or slipping. This clamping method ensures that the coal sample barrel is completely stable during the process of removing the cover, improving the safety and accuracy of the operation.

[0047] According to the device for online disassembly and assembly of the cover of the coal sample barrel according to claim 1, it is characterized in that the barrel blocking assembly 8 includes a second cylinder bracket 81 fixed on one side of the cover removal conveyor line 1, a telescopic cylinder 82 is fixedly connected to one side of the second cylinder bracket 81, the telescopic end of the telescopic cylinder 82 passes through the second cylinder bracket 81 and is fixedly connected to a connecting plate 83, and the second cylinder bracket 81 is located below the barrel cover buffer rack 7. The second cylinder bracket 81 included in the barrel blocking assembly 8 is fixed on one side of the cover removal conveyor line 1, ensuring that the assembly can be closely integrated with the conveyor line, and can timely and accurately control the movement and stay position of the coal sample barrel. The addition of the telescopic cylinder 82 makes the barrel blocking assembly 8 flexible, and its telescopic end can be freely extended and retracted according to the operation needs, thereby realizing the effective blocking or release of the coal sample barrel. This design ensures that the coal sample barrel can stably stay in the specified position when the cover is removed, avoiding position deviation during the transportation process.

[0048] At the same time, the connecting plate 83 is fixedly connected through the telescopic end of the telescopic cylinder 82. Such a design can ensure that the connecting plate 83 can respond quickly when needed, accurately block the coal sample barrel, and quickly withdraw after the operation is completed so that the coal sample barrel can continue to be transported. This design further improves the degree of automation of the operation and reduces the necessity of manual intervention.

[0049] Finally, the second cylinder support 81 is located below the barrel cover buffer rack 7. This layout makes full use of the space of the device, so that the barrel blocking assembly 8 and other equipment such as the barrel cover buffer rack 7 are closely matched, ensuring the compact structure of the entire device without affecting the normal operation of other components. This design not only optimizes the space utilization, but also organically combines the barrel blocking assembly 8 with the lid removal process, thereby improving the continuity and work efficiency of the production line.

[0050] According to claim 1, a coal sample barrel online disassembly and assembly device is characterized in that the second clamping mechanism 10 includes a third cylinder bracket 102 fixed to the first side of the capping conveyor line 2, a double-axis cylinder 101 is fixedly connected above the third cylinder bracket 102, a barrel push block 103 is fixedly connected to the telescopic end of the double-axis cylinder 101, the inner side of the barrel push block 103 is an arc structure, and the thickness of the barrel push block 103 after telescopic expansion is less than the thickness of the frame of the capping conveyor line 2. The second clamping mechanism 10 also includes a baffle bracket 104 fixed to the first side of the capping conveyor line 2, a baffle 104 is fixedly connected to one side of the baffle bracket 104, a second photoelectric sensor 106 is fixedly connected above the baffle bracket 104, and the positions of the baffle 104 and the barrel push block 103 correspond to each other. The second clamping mechanism 10 ensures that the clamping device has a solid support foundation during operation through the third cylinder bracket 102 set on one side of the capping conveyor line 2. The double-axis cylinder 101 above it controls the movement of the barrel push block 103 through telescopic action, making the process of clamping and releasing the coal sample barrel more efficient and flexible. The inner side of the barrel push block 103 is an arc-shaped structure. This design fully considers the shape of the coal sample barrel, can better fit the barrel body, increase the contact area, ensure the uniform distribution of the clamping force, and avoid damage or sliding of the barrel body.

[0051] Secondly, the thickness of the barrel pushing block 103 has been carefully designed. The thickness of the barrel pushing block 103 after extension and contraction is less than the thickness of the frame of the capping conveyor line 2. This not only ensures that the block will not exceed the equipment structure when clamping, avoiding occupying excess space, but also enhances the compactness and integrity of the device, allowing the entire clamping system to operate efficiently in a limited space.

[0052] The second clamping mechanism 10 also includes a baffle support 104 and a baffle 104, which work together with the barrel push block 103 to further fix the accurate position of the coal sample barrel by physical blocking, ensuring that the coal sample barrel will not deviate or shake during the capping process. Crucially, the second photoelectric sensor 106 is located above the baffle support 104, which can monitor the position of the coal sample barrel in real time, ensuring that each operation is performed at a precise time, avoiding the uncertainty of manual control, and greatly improving the degree of automation and operation accuracy.

[0053] According to the device for online disassembly and assembly of covers for coal sample barrels as described in claim 1, it is characterized in that a plurality of support rods 11 are arranged between the cover removal conveyor line 1 and the cover assembly conveyor line 2, a plurality of support rods 12 are fixedly connected below the cover assembly conveyor line 2, and a footrest 13 is fixedly connected below the support rods 12. Firstly, a plurality of support rods 11 are arranged between the cover removal conveyor line 1 and the cover assembly conveyor line 2, and this design greatly enhances the overall stability and rigidity of the conveyor line. The support rods 11 play the role of connecting and supporting the two conveyor lines, ensuring that the operations of cover removal and cover assembly will not be affected by any shaking or deviation when performed on different conveyor lines. This structure not only improves the durability of the conveyor line, but also effectively avoids deformation or failure of the conveyor line due to vibration or external pressure, thereby ensuring the long-term stable operation of the equipment.

[0054] Secondly, a plurality of support rods 12 are fixedly connected to the bottom of the capping conveyor line 2, which further enhance the carrying capacity of the conveyor line and the stability of the overall structure. The support rods 12 distribute the weight of the equipment and the force in operation to more supporting points, thereby reducing the load and deformation risk of the conveyor line during operation, and are particularly suitable for maintaining the stability of the equipment during the operation of heavier coal sample barrels.

[0055] Finally, a foot 13 is fixedly connected to the bottom of the support rod 12, which provides additional support and stability. The foot 13 disperses the weight of the equipment by being in close contact with the ground, preventing the conveyor line from shifting or tilting due to vibration or pressure during work.

[0056] When performing the cover removal operation, the coal sample barrel first moves to the designated position of the first clamping mechanism 9 through the cover removal conveyor line 1. After the conveyor line stops, the first clamping mechanism 9 starts, and the left and right clamps 93 quickly close to firmly clamp the two sides of the coal sample barrel to ensure that the coal sample barrel will not be displaced or shaken during the subsequent cover removal process. Then, the horizontal moving module 4 in the sliding mechanism starts to run, and the barrel cover clamping mechanism 6 is accurately moved to the top of the coal sample barrel. At this time, the vertical moving module 5 starts, and the barrel cover clamping mechanism 6 drops accordingly, firmly grasping the lid of the coal sample barrel. After completing the clamping action, the vertical moving module 5 rises, driving the barrel cover to detach from the coal sample barrel, and realizing the removal of the barrel cover. Subsequently, the horizontal moving module 4 runs again, and the clamped barrel cover is smoothly moved to the top of the barrel cover cache rack 7. After the barrel cover reaches the cache rack, the barrel cover clamping mechanism 6 is released, and the barrel cover is gently placed at the designated position of the cache rack to ensure that it can be smoothly taken in the subsequent cover installation operation. After the entire cover removal operation is completed, the first clamping mechanism 9 releases the fixation of the coal sample barrel, and the barrel blocking assembly 8 simultaneously releases the coal sample barrel, so that it continues to be conveyed along the conveyor line to the next process, ready for the coal sample processing operation.

[0057] When performing the capping operation, the empty coal sample barrel is first conveyed to the predetermined capping position through the capping conveyor line 2, and the conveyor line automatically stops after reaching this position. At this time, the second clamping mechanism 10 starts to start, and the barrel push block 103 and baffle 104 inside it quickly close to clamp the coal sample barrel firmly, ensuring that the coal sample barrel will not move or shake during the subsequent capping operation. This process ensures the accuracy and stability of the entire capping operation and prevents deviation during the capping process. Next, the horizontal moving module 4 in the sliding mechanism starts to move, and the barrel cover clamping mechanism 6 is accurately moved to the top of the barrel cover cache rack 7. When it is above the barrel cover cache rack 7, the vertical moving module 5 of the sliding mechanism starts, and the barrel cover clamping mechanism 6 slowly descends to firmly grasp the barrel cover previously stored on the cache rack.

[0058] When the barrel cover is firmly grasped, the horizontal moving module 4 starts again, driving the barrel cover clamping mechanism 6 to move from the buffer rack to just above the coal sample barrel. After reaching the correct position, the vertical moving module 5 starts working, slowly lowering the barrel cover and accurately installing it on the coal sample barrel. In order to ensure that the barrel cover and the coal sample barrel are tightly sealed, the clamping mechanism and the moving module coordinate their actions during the entire installation process to ensure that the lid is smoothly pressed against the opening of the coal sample barrel. After the installation is completed, the barrel cover clamping mechanism 6 releases the barrel cover, and the vertical moving module 5 immediately retracts to its initial position.

[0059] At this point, the capping operation has been successfully completed, the second clamping mechanism 10 releases the fixation on the coal sample barrel, the coal sample barrel is released again, and the conveyor line is started to convey the coal sample barrel with the cap installed forward to the next processing step or discharge point. Through this series of continuous and precise actions, the capping operation of the coal sample barrel is completed efficiently, and the whole process ensures the seamless connection of each step, which not only improves production efficiency, but also ensures the quality of capping and avoids errors in manual operation.
