Description

Technical Field

[0001] This utility model relates to the field of coal sample testing, specifically a coal sample container packaging and receiving device applicable to automated coal sample processing lines. Background Technology

[0002] To determine relevant parameters of coal, such as total sulfur, calorific value, moisture content (total moisture and analytical water), ash content, volatile matter, fixed carbon, carbon, hydrogen, ash fusion properties, slag carbon content, coking coal, petroleum coke, and briquettes, it is necessary to gradually reduce the weight of the original coal sample to the weight required for analysis, ensuring that its chemical composition or physical properties remain consistent with those before reduction. While automated coal sample processing lines use a multi-module approach to ensure this consistency, current automated lines still require manual intervention for tasks such as canister loading, canister opening, and other tasks related to sample return to the sample storage. This insufficient automation hinders the automated processing of coal samples.

[0003] Currently, a utility model patent with publication number CN214691055U discloses a coal sample storage packaging bag, belonging to the technical field of coal sample storage packaging bags. It includes a packaging bag body with a vacuum mechanism fixedly installed at the top. The vacuum mechanism includes an inlet, an outlet fixedly installed at the bottom of the inlet, a vacuum plug inside the inlet, a dustproof block fixedly installed at the bottom of the vacuum plug, and a first cylindrical cavity inside the dustproof block. The bottom of the first cylindrical cavity has multiple first through holes. This utility model, by setting a vacuum mechanism, places the packaging bag body in a suitable position, then the coal sample enters the packaging bag body through the inlet. After the coal sample reaches a suitable weight, the vacuum plug is used to block the inlet. Because the internal thread of the inlet matches the external thread of the vacuum plug, it effectively protects the moisture and integrity of the coal sample, reducing coal sample loss and moisture depletion.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN214691055U protects the internal moisture value of the coal sample by setting a vacuum mechanism to prevent the increase or decrease of moisture in the coal sample. However, the packaging bag of this patent is too soft to be used by the robotic arms used in the current automated coal sample processing line, and it is not convenient to use. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a coal sample container sealing and receiving device suitable for automated coal sample processing lines. It can automatically store coal sample containers, remove the lids of the coal sample containers when needed, and place the coal sample containers in a convenient gripping position, which can effectively improve the efficiency of coal sample processing.

[0006] To achieve the above objectives, this utility model provides a coal sample container packaging and receiving device suitable for automated coal sample processing lines.

The main frame is fixedly installed in the automated coal sample processing line and is controlled by a machine... The robotic arm retrieves sample containers. Inside the main frame, a dispensing robotic arm is fixedly mounted via a bracket. Sample container storage racks and an automatic capping device are fixedly mounted at the front and rear of the dispensing robotic arm, respectively. A temporary storage platform is provided on the side of the automatic capping device, and a receiving / dispensing device is mounted on the same side of the sample container storage rack. The automatic capping device is mounted on the main frame via a capping device frame. Inside the capping device frame, a capping drive motor is movably mounted via a slide rail and bracket. The output shaft of the capping drive motor drives and connects to a capping claw opening / closing control mechanism. The capping claw opening / closing control mechanism has a built-in pneumatic switch that controls the opening and closing of the three fingers of the capping claw. A sample container clamp is fixedly mounted inside the capping device frame directly below the capping claw. A capping claw lifting drive motor controls the lifting and lowering of the capping claw via a lead screw.

[0007] In addition, the coal sample container sealing and receiving device for automated coal sample processing lines proposed in the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, the dispensing robotic arm includes a translation control motor, a translation control shaft, a control belt, a translation track, a lifting track, a lifting control belt, a robotic arm, and a lifting control motor. Two horizontal translation tracks are installed in the main frame by brackets. The translation control motor drives the lifting track to move back and forth on the translation track through the translation control shaft, transmission wheel, and control belt. The lifting control motor drives the robotic arm to move back and forth on the lifting track through the transmission wheel and lifting control belt.

[0009] As a further improvement of this utility model, the robotic arm includes a robotic arm base, a rotary control motor, a robotic arm telescopic control motor, a robotic arm telescopic slide rail, and a sample container robotic arm. The robotic arm base is movably mounted on the lifting track via the slide rail. The rotary control motor controls the robotic arm telescopic slide rail to rotate on the robotic arm base via a bevel gear or a screw. The robotic arm telescopic control motor controls the sample container robotic arm to move back and forth on the robotic arm telescopic slide rail via a lead screw.

[0010] As a further improvement of this utility model, the transceiver device includes a transmitting tube, a sample container transmitting slide rail, and a sample container transmitting lifting platform.

Detailed Implementation

[0020] The following description, in conjunction with the accompanying drawings, describes the coal sample container packaging and receiving device of this utility model, which is suitable for automated coal sample processing lines.

[0021] In Embodiment 1 of this application, as Figures 1 to 3 As shown, this coal sample container packaging and receiving device (hereinafter referred to as "the present invention") applicable to an automated coal sample processing line includes a main frame 1, a receiving and receiving device 2, a sample container storage rack 3, a dispensing robotic arm 4, an automatic capping device 5, a temporary storage platform 6, and sample containers 7. The main frame 1 is fixedly installed in the automated coal sample processing line, and the sample containers 7 are stored and retrieved by the robotic arm. The dispensing robotic arm 4 is fixedly installed inside the main frame 1 by a bracket. The sample container storage rack 3 and the automatic capping device 5 are fixedly installed at the front and rear of the dispensing robotic arm 4, respectively. The temporary storage platform 6 is provided on the side of the automatic capping device 5, and the sample container storage rack 3 is installed on the same side. The sending device 2; the automatic capping device 5 is mounted on the main frame 1 via the capping device frame 51. The capping drive motor 53 is mounted inside the capping device frame 51 via a slide rail and bracket. The output shaft of the capping drive motor 53 is connected to the capping claw opening and closing control machine 57 of the capping claw 56. The capping claw opening and closing control machine 57 of the capping claw 56 has a built-in pneumatic switch to control the opening and closing of the three fingers of the capping claw 56. The sample container fixing clamp 55 is fixedly installed inside the capping device frame 51 directly below the capping claw 56. The capping claw lifting drive motor 52 controls the lifting of the capping drive motor 53 and the capping claw 56 via a lead screw.

[0022] A coal sample storage packaging bag with utility model announcement number CN214691055U (hereinafter referred to as "the patent") protects the moisture inside the coal sample by setting a vacuum mechanism to prevent the increase or decrease of moisture in the coal sample. However, the patent requires manual numbering of the packaging bag, and the packaging bag itself is too soft to be used on the current automated coal sample processing line.

[0023] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figures 4 to 6 As shown, the dispensing robotic arm 4 includes a translation control motor 41, a lifting control belt 46, a robotic arm 47, and a lifting control motor 48. Two horizontal translation tracks 44 are mounted in the main frame 1 via a bracket. The translation control motor 41 drives the lifting track 45 to move back and forth on the translation track 44 via a translation control shaft 42, a transmission wheel, and a control belt 43. The lifting control motor 48 drives the robotic arm 47 to move back and forth on the lifting track 45 via a transmission wheel and a lifting control belt 46. The robotic arm 47 includes a robotic arm base 471, a rotary control motor 472, and a sample container robotic arm 475. The robotic arm base 471 is movably mounted on the lifting track 45 via a slide rail. The rotary control motor 472 controls the rotation of the robotic arm telescopic slide rail 474 on the robotic arm base 471 via a bevel gear or a screw. The robotic arm telescopic control motor 473 controls the sample container robotic arm 475 to move back and forth on the robotic arm telescopic slide rail 474 via a lead screw. The sending device 2 includes a sending tube 21, a sample container sending slide rail 22, and a sample container sending lifting platform 23. The lower end of the sending tube 21 is aligned with the sample container sending lifting platform 23. A motor and a lead screw drive the sample container sending lifting platform 23 to move back and forth on the sample container sending slide rail 22.

[0024] To further optimize the working efficiency of this application, since the plastic bottle mouth of the uncapped sample container 7 becomes elliptical after being clamped by the capping claw 56, the cap cannot be screwed on smoothly, resulting in high resistance during capping. This often leads to the control system judging that the torque has been reached, but the cap is not actually tightened, resulting in bottle explosion and leakage in the pneumatic transmission pipeline. Therefore, the capping claw 56 is equipped with a capping claw cover 54. The centers of the three fingers of the capping claw 56 coincide with the center of the capping claw cover 54, and the inner diameter of the capping claw cover 54 matches the outer diameter of the sample container. During its vertical movement, the centers of the multiple fingers of the capping claw coincide with the center of the capping claw cover 54, which is a hollow cylinder with an inner diameter matching the outer diameter of the sample container. The lifting and lowering process of the capping claw cover 54 corrects the shape of the sample container, effectively preventing bottle explosion and leakage.

[0025] When in use, install the coal sample container sealing and receiving device suitable for the automated coal sample processing line, connect the corresponding lines and make the corresponding adjustments, and the equipment can be put into use.

[0026] When this utility model is used, its specific operation is as follows:

[0027] During use, the packaging and dispensing device of the automated coal sample processing line receives empty sample canisters 7 during idle time and places them on the sample canister storage rack 3. After the automated coal sample processing line starts working, the sample canisters are opened in advance for use. When sample canisters 7 are needed, the translation control motor 41 of the dispensing robotic arm 4 drives the lifting rail 45 along the translation rail 44 to move to the front of the corresponding sample canister 7 via the translation control shaft 42 and the roller drive control belt 43. At the same time, the lifting control motor 48 drives the robotic arm 47 along the lifting rail 45 to move to the front of the corresponding sample canister 7 via the lifting control belt 46. Then, the rotation control motor 472 controls the robotic arm base 471 to align the sample canister robotic arm 475 with the sample canister and unfold it. The robotic arm extension control motor 473 controls the sample canister robotic arm 475 to extend along the robotic arm extension slide rail 474 via the lead screw or gear and rack, and the sample canister robotic arm 475 grasps the sample canister. A sample container 7 is then distributed. The robotic arm 4 resets and moves the sample container 7 to an automatic capping device 5. The sample container 7 is placed in the sample container fixing clamp 55. The cylinder pushes the clamp to hold the lower part of the sample container. At the same time, the capping claw lifting drive motor 52 controls the capping drive motor 53, the capping claw opening and closing control machine 57, and the capping claw 56 to descend along the slide rail through the lead screw. After reaching the position, the capping claw opening and closing control machine 57 controls the three-point capping claw 56 to clamp the lid of the sample container 7. The capping drive motor 53 drives the capping claw opening and closing control machine 57 and the capping claw 56 to rotate through the coupling. After the lid of the sample container 7 is opened, the capping claw 56 clamps the lid of the sample container 7 and resets. The robotic arm 4 takes away the sample container 7 and places it on the temporary storage platform 6 for later use.

[0028] When the automated coal sample processing line issues an instruction to load coal samples into sample container 7, the robotic arm retrieves sample container 7 from the temporary storage table 6, loads the coal sample, and then returns sample container 7 to its original position. The dispensing robotic arm 4 then removes sample container 7 and places it in the sample container fixing clamp 55 of the automatic capping device 5. The capping claw 56 resets and tightens the cap. The dispensing robotic arm 4 then sends sample container 7 back to the sample container storage rack 3 or onto the sample container sending lifting platform 23 of the receiving and dispatching device 2. A motor-driven screw then propels sample container 7 into the sending pipe 21, ultimately delivering it to the sample storage area. Multiple automatic capping devices 5 effectively improve work efficiency and reduce robotic arm waiting time.

[0029] It should be noted that the capping claw opening and closing control mechanism 57 is mounted on the bracket of the capping drive motor 53 via bearings and a bracket. Therefore, when the capping drive motor 53 drives the capping claw opening and closing control mechanism 57, the capping claw opening and closing control mechanism 57 can drive the capping claw 56 to rotate. Furthermore, the capping claw opening and closing control mechanism 57 is connected to an external air supply device via a pneumatic slip ring, so the rotation of the capping claw opening and closing control mechanism 57 does not affect the use of the capping claw 56. When the cylinder of the sample container fixing clamp 55 pushes the clamp to hold the sample container 7, the opening of the sample container will deform from a circle to an ellipse, which is not conducive to fitting with the container cap. The inner diameter of the capping claw cover 54 is consistent with the outer diameter of the container. During the descent, it covers the container opening and squeezes it back to a circle, without affecting the normal capping and tightening.

[0030] In summary, the coal sample container sealing and receiving device of this utility model embodiment, applicable to automated coal sample processing lines, can automatically store coal sample containers by adding a sealing and sending device to the automated coal sample processing line. The lid of the coal sample container can be automatically removed according to the needs of the processing line, and the coal sample container can be placed in a convenient gripping position, which can effectively improve the efficiency and automation of coal sample processing.
