Description

Technical Field

[0001] The invention relates to the technical field of flame-retardant plate transportation equipment, in particular to a conveying equipment with position correction function used in the production of flame-retardant plates. Background Art

[0002] To maximize space utilization during the transportation of flame-retardant panels, conveyors are typically arranged in a corner-intersection layout, with one section responsible for the horizontal transport of the panels and the other for vertical distribution. When a panel reaches the top of a conveyor section, the perpendicular conveyor rises, allowing the panel to be smoothly transferred to the next conveyor section. However, if the conveyor suddenly stops during this process, the panel will continue to move along the original transport direction for a distance due to inertia. To ensure stable transport of the panels, the section of the conveyor responsible for switching transport directions slows down and intercepts subsequent panels. Only after the panel that has switched directions has completely entered the next conveyor section can the subsequent panels be transported. This deceleration and interception mechanism significantly reduces the transport efficiency of the panels. Furthermore, during transportation, the panels may shift due to external interference or uneven force applied when switching transport directions, increasing the workload of subsequent stacking and transfer. Therefore, we propose a highly efficient conveying device with position correction for the production of flame-retardant panels. Summary of the Invention

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1:

[0038] See also Figure 1-13 The present invention provides a technical solution: a conveying device with position correction for the production of flame-retardant panels, comprising a first roller conveyor 1, a second roller conveyor 2, and a chain conveyor 3. One end of the first roller conveyor 1 is a loading end, the second roller conveyor 2 is perpendicular to the first roller conveyor 1, and the chain conveyor 3 is located above the joint between the first roller conveyor 1 and the second roller conveyor 2 and is perpendicular to the first roller conveyor 1. The device also includes:

[0039] A support rod 4 is installed on the second roller conveyor 2 and is located between two rollers of the second roller conveyor 2. A laser sensor 41 is installed on the support rod 4.

[0040] There are two correcting plates 5 in an "E" shape, which are respectively arranged on both sides of the second roller conveyor 2. The correcting plates 5 are each equipped with a first roller 51 through a shaft;

[0041] The correction mechanism 6 is installed on the second roller conveyor 2 and is connected to the laser sensor 41 and the correction plate 5. After the laser sensor 41 detects the flame retardant plate passing, the correction mechanism 6 drives the two correction plates 5 closer to each other, and the first rollers 51 on the correction plates 5 clamp the two sides of the flame retardant plate, thereby correcting the flame retardant plate;

[0042] A lifting mechanism 7 is installed on one end of the first roller conveyor 1 below the chain conveyor 3, and the lifting mechanism 7 lifts the flame retardant plate above it upward;

[0043] Adsorption mechanism 8, there are multiple adsorption mechanisms 8, which are evenly installed on the chain conveyor 3 and are located directly above the lifting mechanism 7. The adsorption mechanism 8 adsorbs the flame-retardant plate lifted upward by the lifting mechanism 7 and transfers the adsorbed flame-retardant plate to the top of the second roller conveyor 2 through the chain conveyor 3;

[0044] The unloading mechanism 9 is installed on the chain conveyor 3 and is connected to the adsorption mechanism 8. When the flame-retardant plate moves to above the second roller conveyor 2, the unloading mechanism 9 releases the adsorption between the flame-retardant plate and the adsorption mechanism 8.

[0045] like Figure 2 、 3 As shown, the correction mechanism 6 includes a slide bar 61 installed on the second roller conveyor 2, and the slide bar 61 passes through the two correcting plates 5. A servo motor 62 is installed on the slide bar 61, and the servo motor 62 is electrically connected to the laser sensor 41. The output shaft of the servo motor 62 is provided with a pressure sensor, and a driving rod 63 is sleeved on the output shaft of the servo motor 62. The midpoint of the driving rod 63 is in the same straight line with the axis of the output shaft of the servo motor 62. The correction mechanism 6 also includes fixed rods 64 respectively installed on the correcting plates 5, and the fixed rods 64 are rotatably connected to the first connecting rods 65. The two first connecting rods 65 are rotatably connected to the two ends of the driving rod 63 at one end away from the corresponding correcting plate 5.

[0046] When the flame-retardant sheet passes over the laser sensor 41 of the second roller conveyor 2, the laser sensor 41 is triggered, and the laser sensor 41 transmits a signal to the servo motor 62. The timing of turning on the servo motor 62 is determined according to the transmission speed of the second roller conveyor 2. After the servo motor 62 is turned on, it drives the driving rod 63 to rotate. The rotation of the driving rod 63 drives one end of the first connecting rod 65 to move synchronously, and then drives the correcting plates 5 to approach each other through the first connecting rod 65 and the fixed rod 64. The first roller 51 on the correcting plate 5 clamps the two sides of the flame-retardant sheet to drive the flame-retardant sheet to be straightened. During the whole process, the second roller conveyor 2 does not need to stop operating. The first roller 51 can ensure that the flame-retardant sheet can be continuously transported while being corrected. After the roller applies a certain clamping force to the flame-retardant sheet, the resistance to the continued rotation of the output shaft of the servo motor 62 changes and is detected by the pressure sensor. The pressure sensor sends a signal to the servo motor 62 to drive the servo motor 62 to reverse, which is convenient for correcting subsequent flame-retardant sheets.

[0047] like Figure 5 、 6 As shown in Figure 12, the lifting mechanism 7 includes an electric push rod 71 arranged on the first roller conveyor 1 below one end of the chain conveyor 3, and a lifting frame 72 is installed on the electric push rod 71. The middle part of the lifting frame 72 is H-shaped, and the two ends are long bars. Support columns are evenly arrayed on the long bars. The positions of the support columns on the long bars at both ends correspond to each other, and support members 73 are connected between the relative support columns. The support members 73 are staggered with the rollers, and balls 74 are provided on the support members 73. There are several balls 74, and a baffle 75 is installed on the end support member 73, and a buffer pad 76 is installed on the baffle 75.

[0048] like Figure 13 As shown, the support member 73 is composed of three square columns 731, two of which are provided with hemispherical grooves 732 on opposite sides, and the remaining one is provided with hemispherical grooves 732 on both sides. There are several hemispherical grooves 732, which are arranged in a uniform horizontal array on the corresponding square columns 731. The three square columns 731 are connected to limit the position of the ball 74.

[0049] When the first roller conveyor 1 transports the flame retardant plate to the connection with the second roller conveyor 2, the electric push rod 71 is started, which can be achieved according to the transmission speed of the first roller conveyor 1 or by adding a sensor. This is a necessary existing technology in the flame retardant plate transmission equipment. The electric push rod 71 drives the support member 73 to rise through the lifting frame 72. During the rising process of the support member 73, the flame retardant plate is lifted upward. At this time, the bottom surface of the flame retardant plate is supported by a number of uniformly arrayed balls 74. In the process of lifting the flame retardant plate, the baffle 75 on the support member 73 consumes the kinetic energy of the flame retardant plate continuing to move forward due to inertia, and the buffer pad 76 prevents the flame retardant plate from being damaged by hard contact with the baffle 75.

[0050] like Figure 9 As shown, the adsorption mechanism 8 includes a cylindrical rod 81 installed on the conveying plate in the chain conveyor 3, and the cylindrical rod 81 is rotatably connected to the conveying plate in the chain conveyor 3. A negative pressure air pump 82 is slidably installed on the cylindrical rod 81, and the air suction port of the negative pressure air pump 82 is connected to a five-way pipe 83. One of the ports of the five-way pipe 83 is in the middle position and is connected to the air suction port of the negative pressure air pump 82. The other four ports are in opposite directions and are distributed in a trapezoidal shape, and adsorption parts 80 are installed on the four ports of this part.

[0051] like Figure 10 As shown, the adsorption component 80 includes a first fixing ring 801 installed on a through-hole in a trapezoidal distribution of the five-way tube 83, a first circular groove 802 is opened in the middle of the first fixing ring 801, a first annular plate 803 is installed in the first circular groove 802, a spring 804 is installed on one side of the first annular plate 803, a second annular plate 805 is installed on the side of the spring 804 away from the first annular plate 803, a second fixing ring 806 is connected to the outer shell of the second annular plate 805, a second circular groove 807 is opened in the second fixing ring 806, the second annular plate 805 is located inside the second circular groove 807, a suction cup 808 is installed on the second fixing ring 806, and also includes metal bellows 809 respectively installed on the first fixing ring 801 and the second fixing ring 806, the metal bellows 809 wraps the spring 804, and a sealing ring 810 is installed on the adjacent side, and the two sealing rings 810 are both magnet rings with embedded sealing strips.

[0052] As the flame retardant plate rises, it fits against the suction cup 808, and the negative pressure air pump 82 extracts the air in the suction cup 808 through the five-way pipe 83, the first fixing ring 801, the metal bellows 809, and the second fixing ring 806. At this time, the flame retardant plate is adsorbed on the suction cup 808. During this process, the chain conveyor 3 and the first roller conveyor 1 continue to operate. After the suction cup 808 adsorbs the flame retardant plate, the lifting mechanism 7 is reset to facilitate the lifting of subsequent flame retardant plates in the first roller conveyor 1. While the chain conveyor 3 is operating, the flame retardant plate is driven by the suction cup 808 for synchronous transmission. The ball 74 on the support 73 can effectively reduce the friction between the suction cup 808 and the flame retardant plate when they are just in contact and not adsorbed stably, so that the suction cup 808 is faster and more stable when adsorbing the flame retardant plate.

[0053] It should be noted that when existing equipment transfers flame-retardant plates between conveyors, the first conveyor will not be opened until the flame-retardant plates are completely separated from the first conveyor to prevent collision between the front and rear materials. This results in the transferred flame-retardant plates needing to move at least the length or width of their own. In this device, the distance the flame-retardant plates are moved upward only needs to be greater than the thickness of the flame-retardant plates, and then the lifting mechanism 7 can be reset. The displacement distance of the flame-retardant plates is much smaller than that of traditional equipment. The flame-retardant plates maintain a suitable distance between each other, and can be continuously transported without stopping, which greatly improves efficiency.

[0054] like Figure 4 As shown, the unloading mechanism 9 includes an L-rod 91 relatively fixed on the chain conveyor 3 close to the second roller conveyor 2, and a second roller 92 is mounted on the L-rod 91 through an axis. The minimum spacing between the two second rollers 92 is smaller than the spacing between the two openings in the five-way pipe 83 that are trapezoidally distributed on the long side.

[0055] As the chain conveyor 3 continues to transport the flame-retardant plate through the adsorption mechanism 8, under the action of the suction cup 808 connecting component and the flame-retardant plate, the metal bellows 809 tends to be in a straight state, and the second fixing ring 806 in the adsorption member 80 contacts the second roller 92. The second roller 92 squeezes the second fixing ring 806. In this state, the second fixing ring 806 drives the metal bellows 809 and the spring 804 to bend gradually, and then the closed ring 810 between the metal bellows 809 appears partially. The flame retardant plates are separated, and a large amount of external gas enters the suction cup 808. The adsorption force of the suction cup 808 is weakened, and the flame retardant plates fall onto the second roller conveyor 2 under the gravity of the flame retardant plates themselves, and are corrected by the correction mechanism 6 to facilitate subsequent transmission and stacking. The outer diameter of the spring 804 is equal to the inner diameter of the metal bellows 809. After passing through the second roller 92, the metal bellows 809 is reset under the action of the spring 804, and the two closed rings 810 are re-fitted to facilitate the adsorption of subsequent flame retardant plates.

[0056] like Figure 7 As shown, a guiding mechanism 10 is installed on the chain conveyor 3, and the guiding mechanism 10 is connected to the adsorption mechanism 8. By restricting the moving trajectory of the adsorption mechanism 8, the moving trajectory of the flame-retardant plate sucked by the adsorption mechanism 8 is changed. It includes a Z-shaped guide rail 101 relatively opened on the chain conveyor 3, and also includes a guide rod 102 installed on the negative pressure air pump 82. The two ends of the guide rod 102 are respectively located in the Z-shaped guide rail 101 on one side, and the two sides of the Z-shaped guide rail 101 are arc-shaped guide bars 103.

[0057] When the adsorption mechanism 8 moves to the top of the second roller conveyor 2 with the operation of the chain conveyor 3, under the guidance of the Z-shaped guide rail 101, the guide rod 102 drives the negative pressure air pump 82 to move downward, and then drives the flame retardant plate to move downward through the connecting parts of the negative pressure air pump 82 and the suction cup 808, thereby reducing the distance between the flame retardant plate and the second roller conveyor 2, and preventing the flame retardant plate from falling and causing damage when it is separated from the suction cup 808. The arc-shaped guide strip 103 can ensure that the guide rod 102 can re-enter the Z-shaped guide rail 101 after rotating to the top around the chain conveyor 3.

[0058] A spur gear 811 is slidably sleeved on the cylindrical rod 81, and a synchronous rotation design is made between the spur gear 811 and the cylindrical rod 81, which can be achieved by opening a slide groove on one side and setting a slide rod on the other side. This is a common means in the prior art. A spring telescopic rod 814 is fixed under the spur gear 811, and one end of the spring telescopic rod 814 is fixed to the negative pressure air pump 82. A first end face gear 815 is fixed on the chain conveyor 3, and a second end face gear 816 is fixed on the spur gear 811. The first end face gear 815 is penetrated by the cylindrical rod 81, and the two are rotatably connected. Under the action of the spring telescopic rod 814, the first end face gear 815 fits with the second end face gear 816.

[0059] The spring telescopic rod 814 drives the second end face gear 816 to always engage with the first end face gear 815, effectively preventing the adsorption mechanism 8 from rotating due to reasons such as the gravity of the components themselves.

[0060] A reversing plate 812 is installed above the chain conveyor 3 , and a tooth groove 813 is provided on the top of the reversing plate 812 . There are several tooth grooves 813 , which are located on one side of the moving track of the spur gear 811 and can mesh with the spur gear 811 .

[0061] Under the operation of the chain conveyor 3, after the adsorption mechanism 8 moves to the top of the chain conveyor 3, the spur gear 811 is in hard contact with the tooth groove 813 on the reversing plate 812. As the chain conveyor 3 continues to operate, the spur gear 811 starts to rotate under the guidance of the tooth groove 813. The teeth of the first end face gear 815 and the second end face gear 816 are both arc-shaped, and the arc is relatively gentle. The spur gear 811 drives the other parts of the adsorption mechanism 8 to rotate through the cylindrical rod 81. When the spur gear 811 passes through the tooth groove 813, the spur gear 811 rotates exactly 180°. This design can prevent the spring 804 from undergoing irreversible deformation due to long-term unidirectional bending, which affects the contact and adsorption force between the suction cup and the flame retardant plate, and thus affects the adsorption effect. After each adsorption, the entire adsorption mechanism 8 will rotate 180° under the guidance of the tooth groove 813 on the reversing plate 812 and the spur gear 811. When the flame retardant plate is adsorbed again, compared with the last adsorption, the extrusion of the second roller 92 drives the spring 804 to deform to the other side of itself, thereby increasing the stability of the equipment.

[0062] Working principle: When the first roller conveyor 1 conveys the flame-retardant plate to the connection with the second roller conveyor 2, the electric push rod 71 is started. This can be achieved according to the transmission speed of the first roller conveyor 1 or by adding a sensor. This is a necessary existing technology in the flame-retardant plate transmission equipment. The electric push rod 71 drives the support member 73 to rise through the lifting frame 72. During the rising process of the support member 73, the flame-retardant plate is lifted upward. At this time, the bottom surface of the flame-retardant plate is supported by a number of uniformly arrayed balls 74. In the process of lifting the flame-retardant plate, the baffle 75 on the support member 73 consumes the kinetic energy of the flame-retardant plate continuing to move forward due to inertia, and the buffer pad 76 prevents the flame-retardant plate from being damaged by hard contact with the baffle 75.

[0063] As the flame retardant plate rises, it fits against the suction cup 808, and the negative pressure air pump 82 extracts the air in the suction cup 808 through the five-way pipe 83, the first fixing ring 801, the metal bellows 809, and the second fixing ring 806. At this time, the flame retardant plate is adsorbed on the suction cup 808. During this process, the chain conveyor 3 and the first roller conveyor 1 continue to operate. After the suction cup 808 adsorbs the flame retardant plate, the lifting mechanism 7 is reset to facilitate the lifting of subsequent flame retardant plates in the first roller conveyor 1. While the chain conveyor 3 is operating, the flame retardant plate is driven by the suction cup 808 for synchronous transmission. The ball 74 on the support 73 can effectively reduce the friction between the suction cup 808 and the flame retardant plate when they are just in contact and not adsorbed stably, so that the suction cup 808 is faster and more stable when adsorbing the flame retardant plate.

[0064] As the chain conveyor 3 continues to transport the flame-retardant plate through the adsorption mechanism 8, the second fixing ring 806 in the adsorption member 80 contacts the second roller 92, and the second roller 92 squeezes the second fixing ring 806. Under the action of the suction cup 808 connecting component and the flame-retardant plate, the metal bellows 809 tends to be in a straight state. In this state, the second fixing ring 806 drives the metal bellows 809 and the spring 804 to bend continuously, and then the closed ring 810 between the metal bellows 809 is partially separated. At this time, a large amount of external gas enters the suction cup 808, and the adsorption force of the suction cup 808 is weakened. Under the gravity of the flame-retardant plate itself, it falls onto the second roller conveyor 2 and is corrected by the correction mechanism 6 to facilitate subsequent transportation and stacking. After passing the second roller 92, under the action of the spring 804, the metal bellows 809 is reset, and the two closed rings 810 are re-fitted to facilitate the adsorption of subsequent flame-retardant plates.

[0065] When the adsorption mechanism 8 moves to the upper part of the rear half of the second roller conveyor 2 as the chain conveyor 3 operates, under the guidance of the Z-shaped guide rail 101, the guide rod 102 drives the negative pressure air pump 82 to move downward, and then drives the flame retardant plate downward through the connecting parts of the negative pressure air pump 82 and the suction cup 808, thereby reducing the distance between the flame retardant plate and the second roller conveyor 2, and preventing the flame retardant plate from falling and causing damage when the flame retardant plate is separated from the suction cup 808. The arc-shaped guide strip 103 ensures that the guide rod 102 can re-enter the Z-shaped guide rail 101 after rotating to the upper part around the chain conveyor 3;

[0066] When the flame-retardant sheet passes over the laser sensor 41 of the second roller conveyor 2, the laser sensor 41 is triggered, and the laser sensor 41 transmits a signal to the servo motor 62. The timing of turning on the servo motor 62 is determined according to the transmission speed of the second roller conveyor 2. After the servo motor 62 is turned on, it drives the driving rod 63 to rotate. The rotation of the driving rod 63 drives one end of the first connecting rod 65 to move synchronously, and then drives the correcting plates 5 to approach each other through the first connecting rod 65 and the fixed rod 64. The first roller 51 on the correcting plate 5 clamps the two sides of the flame-retardant sheet to drive the flame-retardant sheet to be straightened. During the whole process, the second roller conveyor 2 does not stop operating. The first roller 51 can ensure that the flame-retardant sheet can be continuously transported while being corrected. After the roller applies a certain clamping force to the flame-retardant sheet, the pressure sensor sends a signal to the servo motor 62 to drive the servo motor 62 to reverse, so as to facilitate the correction of subsequent flame-retardant sheets.

[0067] The entire equipment does not need to stop or reduce the transmission rate during transportation, which greatly improves the transmission efficiency of flame retardant panels.
