Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gypsum board production line, and particularly relates to a paper-faced gypsum board oven accurate positioning distribution conveying device and a control method. BACKGROUND

[0002] In the production process of the gypsum board production line, after the gypsum board is formed by plastering, the gypsum board needs to be sent into an oven for drying. In order to improve the efficiency, the gypsum board is usually dried in multiple layers of drying chambers at the same time, which inevitably involves the problem of layering and distribution of the gypsum board.

[0003] In the prior art, a distribution bridge is usually used to redistribute the gypsum board. The distribution bridge conveys the redistributed gypsum board into each layer of the drying chamber of the oven. When the distribution bridge is tilted to convey the gypsum board, since the distribution bridge is usually fixed in the prior art, the horizontal distance between the outlet end of the distribution bridge and the oven changes when the distribution bridge is rotated to change the inclination angle to switch between different drying layers. The horizontal distance between the distribution bridge and the oven always changes, which means that there is a large gap in the conveying belt during the conveying process of the distribution bridge, which can easily affect the shape of the wet gypsum board, such as deformation of the board, which can easily cause quality problems of the gypsum board.

[0004] If the gap is filled and the conveying of the gypsum board is stabilized during the layering and distribution of the gypsum board by the distribution bridge, the board problems caused by the horizontal gap due to the rotation of the distribution bridge for layering and feeding can be greatly reduced.

[0060] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0061] The present application is applicable to the technical field of gypsum board production line, mainly aiming at the process of distributing and feeding the formed wet board into the oven for drying in layers.

[0062] In the prior art, the gypsum board is distributed into the layers of the oven by a distribution bridge. Since the distribution bridge is usually fixed, the horizontal distance between the distribution bridge and the oven changes when the distribution bridge is tilted to match different layer heights of the oven. When the distribution bridge is tilted to the highest layer, a large gap exists between the distribution bridge and the oven, which may cause the deformation of the board and affect the quality of the board when the wet board is transported through the gap.

[0063] The present application sets a fixed-length distribution bridge and a fixed-height oven chamber. The angle sensor and the distance sensor are used to monitor the tilt angle of the distribution bridge and the horizontal distance between the distribution bridge and the oven. The control system compares the difference between the detection data and the target data and adjusts the rotation angle of the distribution bridge and the horizontal movement distance to match the target layer height of the chamber, so as to realize accurate positioning and close matching, thereby greatly reducing the adverse effects of the large gap between the distribution bridge and the oven on the gypsum board.

[0064] As shown in Figure 1 and Figure 3 The present application provides a precise positioning and distribution conveying device for a gypsum board oven, which comprises a control system 6, a distribution bridge 1 arranged at the board inlet of the oven 8, an angle sensor 2 installed on a rotating mechanism 5 and used to detect the tilt angle of the distribution bridge 1, a distance sensor 3 arranged at the rotating end of the distribution bridge 1 and used to detect the horizontal distance between the rotating end of the distribution bridge 1 and the board inlet of the oven, a horizontal movement mechanism 4 connected below the distribution bridge 1 and used to drive the horizontal movement of the distribution bridge 1, and a rotating mechanism 5 arranged below the end of the distribution bridge 1 and installed on the horizontal movement mechanism 4 and used to drive the tilt rotation of the distribution bridge 1.

[0065] The angle sensor 2, the distance sensor 3, the horizontal movement mechanism 4 and the rotating mechanism 5 are connected with the control system 6, respectively. The layer height of each layer of the oven 8 is preset in the control system 6. The control system 6 receives the detection results of the angle sensor 2 and the distance sensor 3. The process of the control system regulating the precise switching and matching of the distribution bridge to different layer heights of the oven chamber is as follows:

[0066] The control system 6 obtains the compensation value of the tilt angle and the horizontal distance of the distribution bridge 1 from the current tilt angle and the horizontal distance of the distribution bridge 1 to the target layer height of the next step according to the comparison result of the tilt angle and the horizontal distance of the distribution bridge 1 to the target layer height of the next step. The control system 6 controls the horizontal moving mechanism 4 and the rotating mechanism 5 to perform corresponding actions according to the horizontal compensation value and the angle compensation value respectively to make the distribution bridge 1 position and dock with the target layer height.

[0067] The control system 6 includes a control unit 61 and a data processing unit 62 electrically connected with the control unit 61. The angle sensor 2 and the distance sensor 3 are electrically connected with the data processing unit 62 respectively. The rotating mechanism 5 and the horizontal moving mechanism 4 are connected with the control unit 61 respectively. The control unit 61 controls the rotating mechanism 5 and the horizontal moving mechanism 4 to perform actions according to the data processing result of the data processing unit 62 to make the distribution bridge 1 switch to dock with different layer heights of the oven 8.

[0068] Specifically, the angle sensor 2 detects the tilt angle of the distribution bridge 1 and transmits the measured angle to the data processing unit 62. The tilt angle value of the distribution bridge 1 when the distribution bridge 1 docks with different layer heights of the oven is pre-stored in the data processing unit 62.

[0069] The data processing unit 62 determines the layer number corresponding to the height of the discharge end of the distribution bridge 1 according to the detection value of the angle sensor 2, and determines the tilt angle compensation value required for the distribution bridge 1 to achieve the target layer height according to the comparison result of the current tilt state of the distribution bridge 1 and the tilt angle value when the distribution bridge 1 reaches the target state. The control unit 61 controls the rotating mechanism 5 to work according to the tilt angle compensation value.

[0070] Similarly, the distance sensor 3 detects the horizontal distance between the rotating end of the distribution bridge 1 and the oven 8 and transmits the detected distance to the data processing unit 62. The horizontal distance between the rotating end of the distribution bridge 1 and the oven 8 when the distribution bridge 1 docks with different layer heights of the oven is pre-stored in the data processing unit 62.

[0071] The data processing unit 62 determines the horizontal distance compensation value required for the distribution bridge 1 to achieve the target layer height according to the comparison result between the detection distance of the distance sensor 3 and the horizontal distance between the rotating end of the distribution bridge 1 and the oven 8 when the distribution bridge 1 reaches the target state. The control unit 61 controls the horizontal moving mechanism 4 to work according to the horizontal distance compensation value.

[0072] In other words, in this embodiment, the number of layers in the oven is fixed, the inlet height of each chamber is known and fixed, the length of the feeding end of the distribution bridge 1 is fixed, the distribution bridge connects to the oven inlet for feeding, and the overall structure forms a triangle, similar to a ladder leaning against a wall. By changing the inclination angle of the ladder, the height at which the end of the ladder abuts against the wall varies. Figure 4 As shown in the schematic diagram of the triangle variation, in this embodiment, since the feeding length of the distribution bridge is fixed, the length of the hypotenuse of the triangle is known and fixed. The inlet height of each chamber of the oven 8 is fixed, which means the target height is fixed. Corresponding to the triangle, this means that the length of one right-angled side of the triangle is known and fixed. According to the Pythagorean theorem, the length of the other right-angled side can be obtained, which is the target horizontal distance between the rotating end of the distribution bridge and the oven. The lengths of the three sides of the triangle are known. The target tilt angle of the distribution bridge can be solved by using inverse trigonometric functions. Based on the target horizontal distance, the target tilt angle, and the currently monitored horizontal distance and tilt angle, the horizontal movement distance and rotation angle required to achieve the target docking tilt state of the distribution bridge can be obtained.

[0073] Furthermore, since the feeding length of the distribution bridge 1 is known and fixed (the hypotenuse of the triangle) and the target layer height is known and fixed, according to the Pythagorean theorem, when the distribution bridge is aligned with the target layer height of the oven, the tilt state of the distribution bridge is uniquely fixed. In other words, if the target state of the distribution bridge 1 is quantified by data, it means that the distribution bridge corresponds to several sets of target state data for the number of chambers in the oven. The data in each set of target state data includes the number of target layers and the corresponding layer height (the length of the vertical right-angled side of the triangle), the tilt angle of the distribution bridge when it is aligned with the target layer height, and the horizontal distance between the rotating end of the distribution bridge and the target layer height of the oven (the horizontal right-angled side of the triangle). These sets of data can be regarded as known and fixed. The data processing unit 62 can determine the number of layers corresponding to the height of the feeding end of the distribution bridge 1 based on the comparison result between the detected data value and the known state data set values. By comparing the current position with the target layer height, it can determine whether to move the end of the distribution bridge 1 upward or downward.

[0074] For example, the oven 8 is specified to have 12 drying chambers. The distribution bridge needs to switch and move between the entrances of the twelve chambers to achieve docking and feeding. The docking sequence of the distribution bridge 1 is 1-3-5-7-9-11-12-10-8-6-4-2-1, and so on.

[0075] Although the target state data values ​​for each group are different, since the ascending and descending processes follow the rule of sending a plate every other layer, it can be understood that the direction of movement is essentially fixed. During the continuous ascending process, a plate is sent every other layer, and after reaching the top layer, a plate is sent. During the continuous descending process, a plate is sent every other layer.

[0076] To solve the above technical problems, the application further provides the following technical solutions:

[0077] A control method for accurately positioning a distribution conveying device of a gypsum board oven, as shown in Figure 5 , comprises the steps of:

[0078] Step 100: determining a target layer height and an inclination angle of a distribution bridge when docking the target layer height;

[0079] Step 200: the control system determines, according to a current inclination angle of the distribution bridge, a horizontal distance between the distribution bridge and the oven, a function relationship between the inclination angle of the distribution bridge when docking the target layer height and the horizontal distance between the distribution bridge and the oven, an inclination angle compensation value and a horizontal distance compensation value of the distribution bridge when docking a next target layer height from the current inclination angle and the horizontal distance;

[0080] Step 300: the control system adjusts the working state of the horizontal moving mechanism and the rotating mechanism according to the horizontal compensation value and the inclination angle compensation value of the distribution bridge, so that the distribution bridge docks the target layer height.

[0081] In general, the target layer height and the corresponding inclination angle of the distribution bridge are determined, the moving direction is determined, the inclination angle and the horizontal position of the distribution bridge are adjusted to dock the corresponding layer height, and the function relationship in step 200 is expressed as:

[0082]

[0083] and

[0084] According to the theoretical analysis process, the steps and the function relationship, the application provides a specific calculation process:

[0085] The length between the rotating end of the distribution bridge 1 and the discharging end is set as B, the layer height of the oven is set as h, the measurement value of the angle sensor 2 is set as β, and the measurement value of the distance sensor 3 is set as S when the distribution bridge 1 works;

[0086] When the distribution bridge 1 docks the target layer height, the target horizontal distance between the rotating end of the distribution bridge 1 and the oven 8 is set as A, the inclination angle of the distribution bridge 1 is set as α, the horizontal distance compensation value required for the distribution bridge 1 to reach the state of docking the target layer height from the current real-time state is set as X, and the inclination angle compensation value required for the distribution bridge 1 to reach the state of docking the target layer height from the current real-time state is set as Δα;

[0087] According to the Pythagorean theorem, A 2 +h 2 =B 2 , according to the trigonometric function relationship,

[0088] The horizontal distance compensation value of the distribution bridge 1 is represented as:

[0089] The angle compensation value of the distribution bridge 1 is represented as:

[0090] The calculation methods of the two compensation values are different when the end of the distribution bridge 1 moves up and down, and the calculation methods of the action compensation values of the up and down movements are given as follows:

[0091] When the detection result of the angle sensor 2 is greater than the value of a or the detection result of the distance sensor 3 is less than the value of A, the data processing unit 62 determines that the control unit 61 controls the rotating mechanism 5 to rotate inward by the angle compensation value Δα and controls the horizontal moving mechanism 4 to move away from the oven 8 by the horizontal distance compensation value X at the same time;

[0092] When the end of the distribution bridge 1 moves down, the calculation methods of the two compensation values are represented as:

[0093]

[0094]

[0095] Conversely, when the detection result of the angle sensor 2 is less than the value of a or the detection result of the distance sensor 3 is greater than the value of A, the data processing unit 62 determines that the control unit 61 controls the rotating mechanism 5 to rotate outward by the angle compensation value Δα and controls the horizontal moving mechanism 4 to move close to the oven by the horizontal distance compensation value X at the same time.

[0096] When the end of the distribution bridge 1 moves up, the calculation methods of the two compensation values are represented as:

[0097]

[0098]

[0099] Specifically, the distribution bridge 1 includes a support frame 11 and a belt roller group 12 installed on the support frame 11, and the support frame 11 and the belt roller group 12 are common existing technologies, and the structure and function implementation process are not described in detail here.

[0100] In the embodiment, the horizontal moving mechanism 4 and the rotating mechanism 5 are integrated and installed at the rotating end of the distribution bridge, and in detail, the horizontal moving mechanism 4 includes a slide and a sliding rod 42 installed on the slide, and the distribution bridge 1 is connected to the sliding rod 42 through a rotating rod 31, the rotating rod 31 is inserted into the support frame 11, the rotating rod 31 is driven to rotate under the action of the motor, the rotating rod 31 rotates and drives the distribution bridge 1 to rotate as a whole to change the inclination angle of the distribution bridge 1, and the sliding rod 42 drives the distribution bridge to move along the slide to change the horizontal distance between the rotating end of the distribution bridge 1 and the oven.

[0101] The slide rail comprises slide frames 41 arranged at the two sides of the bottom of the distribution bridge 1, slide grooves 43 for the sliding of slide rails 42 are arranged inside the two slide frames 41, the two ends of the slide rails 42 are installed in the two slide grooves 43, the end of the rotating rod 31 is fixedly installed on the slide rail 42, horizontal drive cylinders 44 and rotating drive motors 33 are respectively installed on the two slide frames 41, the horizontal drive cylinders 44 are connected with the slide rails 42 and are used to drive the slide rails 42 to move along the slide grooves 43, the output shafts of the rotating drive motors 33 are coaxially connected with the slide rails 42 and are used to drive the slide rails 42 to rotate.

[0102] In detail, as shown in Figure 1 and Figure 2 , the rotating rod 31 is inserted through the inner frame rod of the support frame 11, the connecting cross rod 32 is arranged at the side of the slide rail 42, the two ends of the connecting cross rod 32 are connected with the two ends of the slide rail 42 through the buffer shafts 34, the output shafts of the horizontal drive cylinders 44 are connected on the connecting cross rod 32, and the slide rail 42 can rotate around the buffer shafts 34.

[0103] The connecting cross rod 32 indirectly connects the horizontal drive cylinders 44 and the slide rails 42 together, so as to avoid the influence of the direct connection between the horizontal drive cylinders 44 and the slide rails 42 on the rotation of the slide rails 42, the buffer shafts 34 are sleeved on the slide rails 42 or the slide rails 42 and the output shafts of the rotating drive motors 33, and remain stationary, while the slide rails 42 or the output shafts of the rotating drive motors can rotate relative to the buffer shafts 34.

[0104] The angle sensor 2 is installed on the slide rail 42 and synchronously rotates with the slide rail 42, so as to detect the rotating angle of the slide rail 42, the distance measuring sensor 3 is installed on the buffer shaft 34, the measuring end of the distance measuring sensor 3 is opposite to the oven, and the detection end of the distance measuring sensor 3 is on the straight line where the central axis of the slide rail 42 is located, so as to ensure that the distance detected by the distance measuring sensor 3 is the horizontal distance from the central axis of the slide rail 42 to the oven, and the rotating end of the distribution bridge 1 is in the same vertical plane as the slide rail 42, that is, the detection distance of the distance measuring sensor 3 is the horizontal distance from the rotating end of the distribution bridge 1 to the oven.

[0105] In addition, the compensation feeding roller set 7 is connected on the rotating end of the distribution bridge 1, and is used to compensate the horizontal distance compensation value generated by the movement of the distribution bridge 1. Since the distribution bridge 1 is arranged in a movable manner to compensate the gap between the discharging end and the oven, but the distribution bridge 1 is easy to cause the length of the feeding end of the distribution bridge 1 to be insufficient when moving to the side of the oven. Therefore, the compensation feeding roller set 7 is arranged at the tail end of the distribution bridge 1, that is, the feeding end, so as to prevent the problem that the length of the feeding end is insufficient due to the movement of the distribution bridge to compensate the discharging end, and the compensation of the feeding end will not affect the feeding of the feeding part (the length of the triangular hypotenuse) of the distribution bridge 1.
