Description

Technical Field

[0001] This invention relates to the field of garment processing technology, specifically to an intelligent overhead conveyor system for garment production. Background Technology

[0002] In the garment manufacturing industry, overhead conveyor systems are widely used in the transport and processing of fabrics. Traditional overhead conveyor systems typically use a rake-shaped frame with multiple "∩"-shaped openings, each containing a fabric clamp. These clamps usually rely on spring force to create pressure between their ends and adjacent rake teeth, thus holding the fabric in place. In this structure, the fabric is completely vertical, relying on minimal friction to support its full weight. Therefore, fabric often falls during transport on the overhead conveyor line, severely impacting production. To overcome this, the traditional approach is to add friction devices to the rake teeth where the fabric clamps contact. While this prevents fabric from falling, it also increases the difficulty of removing the fabric after all processing steps. Furthermore, fabric can only be removed one piece at a time from the frame, significantly reducing the overall efficiency of the production line.

[0003] To address the aforementioned issues, various improvements have been proposed in the prior art. For example, utility model patent application number CN202222604502.8 provides a hanging frame and its hanging production line, which adds an auxiliary pulling mechanism to the traditional hanging frame. This mechanism pulls the fabric clamps upward to hold the fabric, thereby supporting the fabric through spring force to prevent it from falling. Furthermore, pulling the fabric downward opens the clamps, making it convenient for workers to remove the fabric. However, this improvement still has certain drawbacks; the clamps still need to be manually opened when placing the fabric on them, which still affects the overall efficiency of the production line.

[0004] Therefore, an intelligent overhead conveyor system for garment production is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent overhead conveyor system for garment production. By using magnetic force to control the opening and closing of the fabric clamps, workers do not need to frequently open and close the fabric clamps to remove and place fabrics during operation, thereby improving the working efficiency of the overhead conveyor system.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An intelligent suspended conveyor system for garment production includes a support frame, a main track, branch tracks, a hanger, a track-changing mechanism, and a lifting mechanism. The support frame has a main track and branch tracks. The hanger is slidably mounted on the main track. The highest and lowest points of the branch tracks are respectively equipped with a track-changing mechanism and a lifting structure. The support frame has a mounting block below the lowest point of the branch tracks, and an electromagnet is mounted on the mounting block. The hanger has a mounting seat with multiple openings facing upwards. Each opening has a fabric clamp, and each fabric clamp has two clamping blocks. Both clamping blocks are slidably mounted at the openings. A locking rod is slidably mounted on the mounting seat. Two connecting rods are hinged to the locking rod, and the two connecting rods are respectively hinged to the two clamping blocks. A return spring connects the connecting rods and the clamping blocks. The mounting seat has a locking element for restricting the upward movement of the locking rod.

[0008] During operation, when the electromagnet is energized, the locking rod moves downwards, controlling the two clamping blocks to hold the fabric. A locking mechanism then restricts the upward movement of the locking rod, ensuring the clamping blocks always hold the fabric. Magnetic force releases the locking mechanism's restriction on the locking rod, causing it to move upwards under the force of the return spring. This causes the two clamping blocks to move relative to each other, releasing the fabric. This eliminates the need for manual opening and closing of the fabric clamps when removing or placing fabric, making operation more convenient and effectively improving the efficiency of the overhead conveyor system. With the opening facing upwards, placing fabric is simply a matter of suspending it on the mounting base, further enhancing the system's efficiency. The magnetic attraction of the fabric clamps ensures sufficient friction between the clamps and the fabric, preventing the clamping force from being affected by a decrease in the return spring's elasticity, thus ensuring the stability of the overhead conveyor system.

[0009] Preferably, the locking component includes an unlocking rod slidably mounted on the mounting base. The locking rod is arranged vertically, and the unlocking rod is arranged horizontally. A compression spring connects the unlocking rod to the mounting base. A cylinder is provided on the bracket, and a second mounting block is provided on the cylinder. An electromagnet is provided on the second mounting block. A limiting plate is provided on the unlocking rod, and multiple limiting grooves are formed in the vertical direction on the limiting plate. A limiting block is provided on the locking rod. The limiting block is triangular in shape, and an inclined surface that slopes upwards along the radial direction of the locking rod is provided below the limiting block.

[0010] By squeezing the unlocking rod with a compression spring, the limiting block is embedded inside the limiting groove, thus restricting the upward movement of the locking rod. The unlocking rod is then attracted by an electromagnet, allowing the limiting block to disengage from the limiting groove. At this point, the locking rod, under the elastic force of the return spring, pushes the two clamping blocks relative to each other, thereby opening the fabric clamp and allowing workers to remove the fabric. This ensures the production efficiency of the suspended conveyor system. Alternatively, by extending or retracting the cylinder, the mounting block two blocks the fabric clamp, automatically opening it and effectively guaranteeing the production efficiency of the suspended conveyor system. The multiple limiting grooves ensure that the locking rod can be restricted from moving upwards to any position, thus providing the same clamping force when holding fabrics of different thicknesses.

[0011] Preferably, the unlocking rod is arranged obliquely upward along the horizontal direction, the locking rod is provided with a sliding groove, the limiting block is slidably installed on the sliding groove, and the limiting block is elastically connected to the locking rod.

[0012] By arranging the unlocking lever diagonally upwards in the horizontal direction, when the limiting block is not fully aligned with the limiting groove, the unlocking lever can move diagonally downwards to make the upper wall of the limiting groove fit with the upper wall of the limiting block. This avoids the limiting block and the limiting groove not fitting completely, which would cause the locking lever to spring back and reduce the clamping force of the fabric clip. When the unlocking lever moves at an angle, the lower wall of the limiting groove fits with the limiting block, and the limiting block is squeezed and slides along the slide groove. This avoids the limiting block blocking the movement of the unlocking lever, thus ensuring that the limiting block can be fully engaged in the limiting groove. This prevents the locking lever from springing back due to gaps between the limiting block and the limiting groove, which would cause the fabric clip to loosen.

[0013] Preferably, the mounting block is provided with a detection hole, and a contact sensor is provided inside the detection hole. The contact sensor is located below the locking rod and is electrically connected to the lifting structure.

[0014] By setting up a sensor and electrically connecting it to the lifting structure, when the electromagnet-driven locking rod controls the fabric clamp to hold the fabric, if the worker does not place the fabric in the correct position, the fabric clamp will fail to hold the fabric. As a result, the two clamping blocks will come into contact with each other, increasing the downward movement distance of the locking rod. This will cause the locking rod to touch the sensor, thereby preventing the lifting mechanism from moving. This allows the worker to readjust the position of the fabric and clamp it again, thus preventing the fabric from falling out of the clamp. However, the information of the hanging frame is fixed, and when the fabric falls, it is necessary to accurately locate the hanging frame, which will seriously affect the production efficiency of the suspended conveyor system.

[0015] Preferably, each of the two mounting blocks has a positioning groove, the mounting base has a positioning block, and the notch has an electromagnet.

[0016] Overhead conveyor systems typically have multiple workstations, each performing different procedures. Consequently, the fabric clamps that need to be opened will also differ. By setting positioning slots, positioning blocks on the mounting base can be embedded into these slots. This prevents the electromagnet from failing to control the opening of the corresponding fabric clamps at the workstations due to hanger swaying or center of gravity shift, thus avoiding the need for manual opening of the fabric clamps and ensuring the efficiency of the overhead conveyor system.

[0017] Preferably, the vertical height of the positioning groove is greater than the vertical height of the positioning block, and the positioning groove and the side and bottom surfaces of the positioning block are provided with mutually fitting guide surfaces.

[0018] The height of the hanger is often affected by manufacturing defects and roller wear. Therefore, when the locking rod is attracted, even if the fabric clamp holds the fabric, the locking rod may still come into contact with the sensor, causing a signal error and preventing the suspension conveyor system from operating normally. Therefore, the positioning groove on mounting block one and the bottom surface of the positioning block are provided with guide surfaces. When the hanger is attracted, the mounting base can move upward along the guide surfaces, so that when electromagnet one attracts the locking rod, the height of the mounting base from the sensor remains constant, thus ensuring the normal operation of the suspension conveyor system.

[0019] Preferably, the mounting base is rotatably connected to the hanger, the mounting base is inclined in the horizontal direction, one end of the mounting base is provided with a counterweight, and the mounting block is parallel to the transmission direction of the branch track.

[0020] The mounting base is rotatably connected to the hanger, allowing it to rotate and avoid obstacles when the hanger moves along the main track and branch track. The mounting base is inclined in the horizontal direction, and a counterweight is provided at one end of the mounting base, ensuring that the positioning block always faces the second mounting block. This prevents the positioning block from rotating away from the second mounting block, which would cause the fabric clamp to be attracted by the second electromagnet and unable to open. The first mounting block is parallel to the transmission direction of the branch track. After the mounting base moves and interferes with the installation of the second mounting base, the mounting base can be rotated. At this time, the worker can rotate their body to place the fabric on the hanger, eliminating the need for lateral movement to place the fabric, making it more convenient for the worker to operate and effectively improving the production efficiency of the overhead conveyor system.

[0021] Preferably, the detection hole is provided with an elastic diaphragm, and the upper part of the elastic diaphragm is arc-shaped.

[0022] The elastic diaphragm prevents wire ends and dust from falling and causing false triggering of the sensor, thus affecting the normal operation of the overhead conveyor system. The arc shape at the top of the elastic diaphragm also prevents wire ends from accumulating and causing false triggering of the sensor, thus affecting the normal operation of the overhead conveyor system.

[0023] Preferably, the unlocking rod has an extension section that extends to the outside of the mounting base.

[0024] By extending the extension section, if the unlocking rod gets stuck due to dust or wires, the extension section can be manually pushed by the staff to unlock it, thus preventing the unlocking rod from getting stuck and causing the suspension conveyor system to malfunction.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. The locking rod is moved by magnetic force to control the opening and closing of the fabric clamp. This means that workers do not need to manually control the opening and closing of the fabric clamp when taking off or placing fabric, thus effectively improving the working efficiency of the overhead conveyor system. With the fabric clamp opening facing upward, workers only need to hang the fabric on the mounting base when placing it, making it more convenient and further improving the working efficiency of the overhead conveyor system.

[0027] 2. By setting an unlocking rod with multiple limit slots and setting a limit block on the locking rod, the movement of the unlocking rod is controlled by magnetic force, so that the unlocking rod restricts the upward movement of the locking rod. The locking rod can be restricted to move upward at any position, so that the garment clamp can provide the same clamping force when clamping garments of different thicknesses, and prevent the garments from falling and affecting the normal operation of the suspension conveyor system.

[0028] 3. By arranging the unlocking rod diagonally upwards in the horizontal direction, when the limiting block is not fully aligned with the limiting groove, the unlocking rod can move diagonally downwards to make the upper wall of the limiting groove fit with the upper wall of the limiting block. This avoids the limiting block and the limiting groove not being fully engaged, which would cause the locking rod to spring back and reduce the clamping force of the fabric clip. When the unlocking rod moves at an angle, the lower wall of the limiting groove fits with the limiting block, and the limiting block is squeezed and slides along the slide groove. This avoids the limiting block blocking the movement of the unlocking rod, thus ensuring that the limiting block can be fully engaged in the limiting groove. This prevents the locking rod from springing back due to gaps between the limiting block and the limiting groove, which would cause the fabric clip to loosen. Attached Figure Description

[0036] Please see Figures 1 to 6 This invention provides an intelligent overhead conveyor system for garment production, the technical solution of which is as follows:

[0037] An intelligent overhead conveyor system for garment production includes a support frame 1, on which a main track and branch tracks 2 are mounted. Multiple hangers 3 are rotatably mounted on the main track. A drive unit is mounted on the main track; the drive unit is a prior art device for moving the hangers 3. The branch tracks 2 are curved downwards, and a track-changing mechanism is located at the top of each branch track 2. This track-changing mechanism employs a prior art fork-type transfer mechanism. By controlling the swing of the fork, when the drive unit pushes the hanger 3, the hanger 3 can move onto the fork, allowing it to enter the branch track 2 by gravity. The branch track 2 is at its lowest point... A lifting mechanism 4 is provided, which is a pusher used in the prior art to push the hanger 3 to the main track. A workbench is provided on the ground, and a control switch is provided on the workbench. The control switch on the workbench is activated. A stopper 20 is provided on the branch track 2 to limit the movement of the hanger 3 on the branch guide rail. A mounting block 5 is provided below the lowest point of the branch track 2, and an electromagnet 6 is provided on the mounting block 5. The hanger 3 is provided with a mounting base 7, which has multiple openings 71, and the openings 71 face upwards. Clothing clips 8 are provided on the openings 71, and each clothing clip 8 has two clamping blocks 81. All blocks 81 are slidably installed at the opening 71. A locking rod 82 is slidably installed on the mounting base 7. Two connecting rods 83 are hinged to the locking rod 82. The two connecting rods 83 are respectively hinged to the two clamping blocks 81. A return spring 84 is connected between the connecting rods 83 and the clamping blocks 81. The mounting base 7 is provided with a locking component 9, which includes an unlocking rod 91 slidably installed on the mounting base 7. The locking rod 82 is arranged vertically, and the unlocking rod 91 is arranged horizontally. A compression spring 92 is connected between the unlocking rod 91 and the mounting base 7. A cylinder 93 is provided on the bracket 1. A second mounting block 94 is provided on the cylinder 93. An electromagnet is provided on the second mounting block 94. 2.95. The unlocking rod 91 is provided with a limiting plate 96. The limiting plate 96 has multiple limiting grooves 97 in the vertical direction. The locking rod 82 is provided with a limiting block 98. The limiting block 98 is triangular in shape. Below the limiting block 98 is a slope that is inclined upward in the radial direction of the locking rod 82. The locking rod 82 and the unlocking rod 91 are made of 430 stainless steel. The branch track 2 is divided into a waiting area 201, an unlocking area 202, and a locking area 203. The area from the stop 20 to the top of the branch track 2 is the waiting area 201. The area from the stop 20 to the positioning block 14 is the unlocking area 202. The area from the positioning block 14 to the bottom of the branch track is the locking area 203.During operation, the drive unit drives the hanger 3 to move along the main track. When the hanger 3 moves to the corresponding workstation, the track-changing mechanism is activated, causing the hanger 3 to move to the branch track 2. The hanger 3 can then move under gravity and is stopped by the stopper 20, stopping in the waiting area 201. The operator controls the stopper 20 to open, allowing one hanger 3 to enter the unlocking area 202. At this time, the cylinder 93 extends, pushing the mounting block 94 to block the hanger 3. After the cylinder 93 is fully extended, the electromagnet 95 is activated. The electromagnet 95 attracts the unlocking rod 91 to slide, and the limit of the locking rod 82 is released, causing the return spring 84 to push the locking rod 82 to move. This, through the connecting rod 83, pushes the two clamping blocks 81 to move relative to each other, thereby opening the fabric clamp 8. After clamp 8 is opened, the worker can remove the fabric for processing. By controlling the retraction of cylinder 93, the mounting block 2 94 no longer obstructs the hanger 3. At this time, the hanger 3 can slide to the locking area 203 and move to the bottom of the branch guide rail. At this time, the mounting seat 7 is located above the mounting block 1 5. After the fabric is processed, the worker places the processed fabric at the opening 71. At this time, the electromagnet 1 6 is activated to attract and slide the locking rod 82, so that the locking rod 82 pulls the two clamping blocks 81 to move towards each other through the connecting rod 83, thereby clamping the fabric. The unlocking rod 91 moves under the elastic force of the compression spring 92 and moves the limiting groove 97 to the limiting block 98, restricting the upward movement of the locking rod 82. At this time, the lifting structure is controlled to push the bottom hanger 3. Once inside the main track, the processing of one garment is complete. Multiple limiting grooves 97 are installed, and the locking rod 82 can be moved to any position to restrict its upward movement. This ensures that the garment clamp 8 provides the same clamping force when holding garments of different thicknesses, preventing the garment from falling due to loosening. The stopper 20, electromagnet 2 95, electromagnet 1 6, lifting mechanism 4, and cylinder 93 are all controlled by a control switch. Cylinder 93 is usually in the extended state. When the control switch is pressed, electromagnet 2 95 and electromagnet 1 6 start for 1 second, at which time the worker can remove the garment from the unlocking area 202. After 5 seconds, the lifting structure starts, sending the processed garment hanger 3 to the main track. At this time, cylinder 93 reciprocates. The cylinder 93 extends and reciprocates, causing the hanger 3 in the unlocking area 202 to enter the locking area 203. When the cylinder 93 extends and reciprocates, the stopper 20 is activated, causing the hanger 3 to fall into the unlocking area 202. After the fabric is processed again, the processed fabric is placed on the hanger 3 in the locking area 203. The fabric is then removed from the unlocking area 202 and processed again. The process is repeated by pressing the control switch. The operator does not need to control the opening and closing of the fabric clamp 8. This not only makes it convenient to remove the fabric but also to fix the fabric to the hanger 3, thereby effectively improving the working efficiency of the hanging conveyor system. In addition, the opening 71 of the fabric clamp 8 faces upward, which can suspend the fabric and distribute the weight of the fabric clamp 8, thereby preventing the fabric from falling due to insufficient clamping force.The unlocking rod 91 is arranged diagonally upward in the horizontal direction. A groove 10 is provided on the locking rod 82, and a limiting block 98 is slidably mounted on the groove 10. The limiting block 98 is elastically connected to the locking rod 82 by a spring. When the unlocking rod 91 is arranged diagonally upward in the horizontal direction, it can tilt and move under the action of the compression spring 92. When the limiting block 98 is not fully aligned with the limiting groove 97, the unlocking rod 91 can move diagonally downward to make the upper wall of the limiting groove 97 fit against the upper wall of the limiting block 98. This prevents the limiting block 98 and the limiting groove 97 from not fully engaging, which would cause the locking rod 82 to spring back and reduce the clamping force of the fabric clip 8. When the unlocking rod 91 tilts and moves... When the limiting groove 97 is in contact with the limiting block 98, the limiting block 98 is pressed and slides along the sliding groove 10. This prevents the limiting block 98 from blocking the movement of the unlocking rod 91, thus ensuring that the limiting block 98 can be fully engaged in the limiting groove 97. This avoids gaps between the limiting block 98 and the limiting groove 97, which could cause the locking rod 82 to spring back and loosen the fabric clip 8. The unlocking rod 91 has an extension section 19 that extends to the outside of the mounting base 7. If the unlocking rod 91 is jammed due to dust or wires, it can be unlocked by manually pushing the extension section 19, thus preventing the unlocking rod 91 from jamming and causing the suspension conveyor system to malfunction.

[0038] Mounting block 1 (5) has a detection hole 11, and a contact sensor 12 is installed on the detection hole 11. The contact sensor 12 is located below the unlocking rod 91 and is electrically connected to the lifting structure. When the electromagnet 1 (6) attracts the locking rod 82, if the worker does not place the clothing in the correct position, the clothing clamp 8 will not be able to hold the clothing. Therefore, the two clamping blocks 81 will come into contact with each other, increasing the downward movement distance of the locking rod 82. This will cause the locking rod 82 to touch the sensor 12, thereby preventing the lifting mechanism 4 from moving. This allows the worker to readjust the position of the clothing and clamp it, thus preventing the clothing from falling and affecting the production efficiency of the suspended conveyor system. Mounting block 2 (94) has positioning holes on each mounting block. The mounting base 7 has a positioning block 14 in the groove 13, and an electromagnet 15 inside the notch. When the mounting block 94 blocks the fabric clip 8, the electromagnet 15 is activated. Since the upper part of the hanger 3 is made of iron, it will be attracted by the electromagnet 15, causing the positioning block 14 to be inserted into the positioning groove 13. This prevents the hanger 3 from shaking or shifting its center of gravity, which would cause the electromagnet 95 to fail to control the opening of the fabric clip 8 at the corresponding workstation, requiring manual opening of the fabric clip 8. This ensures the working efficiency of the suspended conveyor system. By setting the height of the electromagnet 15, the attraction of the unlocking rod 91 by the electromagnet 15 can be avoided. The vertical height of the positioning groove 13 is greater than the vertical height of the positioning block 14. The sides and bottom surfaces of the positioning groove 13 and the positioning block 14 are provided with mutually fitting guide surfaces 16. When the hanger 3 is attracted, the mounting base 7 can move upward along the guide surface 16, so that when the electromagnet 6 attracts the locking rod 82, the height of the mounting base 7 from the sensor 12 remains constant. This avoids the problem that the height of the hanger 3 is usually deviated due to manufacturing and roller wear, which would cause the locking rod 82 to contact the sensor 12 even if the fabric clamp 8 holds the fabric when the locking rod 82 is attracted, resulting in signal errors and causing the suspension conveyor system to malfunction. The mounting base 7 is rotatably connected to the hanger 3. The mounting base 7 is inclined in the horizontal direction, and one end of the mounting base 7 is provided with a counterweight 17. The mounting block 5 is parallel to the transmission direction of the branch track 2. The rotatable connection between the mounting base 7 and the hanger 3 allows the hanger 3 to move upward along the main track and the branch track 2. The system can rotate to avoid obstacles. The mounting base 7 is inclined in the horizontal direction, and one end of the mounting base 7 is equipped with a counterweight 17, which ensures that the positioning block 14 always faces the mounting block 2 94. This prevents the positioning block 14 from rotating to the side opposite to the mounting block 2 94, which would cause the fabric clip 8 to be unable to open when attracted by the electromagnet 2 95. The mounting block 1 5 is parallel to the transmission direction of the branch track 2. After the mounting base 7 moves and interferes with the installation of the mounting base 7 2, the mounting base 7 can be rotated. At this time, the worker can rotate his body to place the fabric on the hanger 3, so that the worker can place the fabric without lateral movement, which is more convenient for the worker and effectively improves the production efficiency of the suspended conveyor system. The detection hole 11 is equipped with an elastic diaphragm 18, and the upper part of the elastic diaphragm 18 is arc-shaped.The elastic diaphragm 18 prevents loose threads and dust from falling and causing false triggering of the sensor 12, thus affecting the normal operation of the overhead conveyor system. Furthermore, the arc shape at the top of the elastic diaphragm 18 prevents the accumulation of loose threads, which could also lead to false triggering of the sensor 12 and disrupt the normal operation of the overhead conveyor system.

[0039] Working principle: When the control switch is activated, electromagnets 6 and 95 start simultaneously for 1 second. The hanger 3 located in the locking zone 203 is magnetically attracted by electromagnet 6, causing the locking rod 82 to be attracted and move downward. This causes the locking rod 82 to pull the two clamping blocks 81 towards each other via the connecting rod 83, thereby clamping the fabric. Meanwhile, the unlocking rod 91 moves under the force of the compression spring 92, moving the limiting groove 97 to the limiting block 98, restricting the upward movement of the locking rod 82. The hanger 3 in the unlocking zone 202 is magnetically attracted by electromagnet 95, causing the limiting block 98 to disengage from the limiting groove 97. At this time, the locking rod 82 moves under the force of the return spring 84, and pushes the two clamping blocks 81 towards each other via the connecting rod 83, opening the fabric clamp 8. The worker can then remove the fabric clamp 8. When the fabric is being processed, after electromagnets 6 and 95 are activated for 1 second, the lifting mechanism 4 is activated to send the hanger 3 in the locking area 203 to the main track. After the lifting mechanism 4 is activated for 5 seconds, the cylinder 93 retracts, causing the hanger 3 in the unlocking area 202 to roll down to the locking area 203. The cylinder 93 extends after 1 second. After the cylinder 93 extends, the stopper 20 and electromagnet 15 are activated, causing one hanger 3 in the waiting area 201 to fall to the unlocking area 202. The hanger 3 is attracted by the magnet 3, causing the positioning block 14 to be locked into the positioning groove 13, preventing the hanger 3 from swinging and its position from shifting. At this time, the control switch is activated to control electromagnets 6 and 95 to start again. This process is repeated, so that the workers do not need to manually open and close the fabric clamp 8, thereby effectively improving the production efficiency of the suspended conveyor system.

[0040] When the electromagnet attracts the locking rod 82, if the worker does not place the fabric in the correct position, the fabric clamp 8 will not be able to hold the fabric. Therefore, the two clamping blocks 81 will stick together, increasing the downward movement distance of the locking rod 82. This will cause the locking rod 82 to press against the elastic diaphragm 18, making the elastic diaphragm 18 touch the sensor 12. This will prevent the lifting mechanism 4 from moving. At this time, the worker can manually press the extension section 19 to push the unlocking rod 91 to move and release the restriction on the locking rod 82. Then, the locking rod 82 will reset under the elastic force of the return spring 84, opening the fabric clamp 8. The worker can then place the fabric again and resume normal operation by restarting the control switch.

[0041] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
