Background
The gypsum board edge sealing is to convey a plurality of gypsum boards to an edge sealing machine at fixed intervals in sequence, and the edge sealing machine uniformly presses the edge sealing tape on the side wall of the gypsum board, so that two adjacent gypsum boards are connected by the edge sealing tape. Therefore, it is necessary to cut the edge strip between two adjacent plasterboards to separate the two plasterboards.
At present, the method for automatically cutting off the edge sealing belt mainly adopts a seam searching and cutting mode, namely a photoelectric sensor is arranged on a cutter mechanism which can move along the conveying direction of the gypsum board, when the cutter mechanism moves to search for a gap between two gypsum boards, the movement of the cutter mechanism and the conveying of the gypsum board conveying belt are stopped when the photoelectric sensor detects the gap, and the cutter mechanism acts to cut off the edge sealing belt.
In the working process, as the photoelectric sensor moves from one side of the gap to obtain a light transmission signal, the stop position of the cutter mechanism deviates to one side of the gap, so that the cutter mechanism deviates to one side to cut off the edge sealing strips, and the edge sealing strips of the two gypsum boards are inconsistent in tail breaking length.
In particular, the gypsum boards may slide slightly under the inertia of stopping conveying, gaps between adjacent gypsum boards are generally smaller (within 5 mm), and different sliding distances may exist for each gypsum board, so that the cutter mechanism is difficult to align with the middle position of the gaps precisely, and the situation that the lengths of edge sealing bands of the gypsum boards are inconsistent is caused.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 and 2, the present invention provides a high-precision automatic cutting method for a gypsum board edge sealing tape, comprising, in each cutting cycle:
when the push plate distance measuring sensor 1 detects that a push plate trolley 2 between two adjacent gypsum boards reaches a cutting area, outputting a first distance signal;
The controller controls the gypsum board conveyor to stop according to the first distance signal, and after the gypsum board conveyor stops, the push plate distance measuring sensor 1 detects the distance between the gypsum board conveyor and the push plate trolley 2 and outputs a second distance signal;
the controller controls the sliding table cutters 3 to horizontally slide at two sides of the gypsum board conveyor in a direction parallel to the gypsum board conveying direction according to the second distance signal;
when the sliding table cutter 3 slides to be aligned with the pushing plate trolley 2 according to the second distance signal, the sliding table cutter 3 acts and cuts off the edge sealing band between the two gypsum boards;
After the cutting action of the sliding table cutter 3 is reset, the controller controls the gypsum board conveyor to continuously convey gypsum boards;
The pushing plate trolley 2 is used for keeping the distance value between two adjacent gypsum boards fixed and moving along with the transportation of the gypsum boards.
The automatic cutting method of the embodiment mainly utilizes the push plate ranging sensor 1 to detect the position of the push plate trolley 2 for separating two adjacent gypsum boards, so that when the push plate ranging sensor 1 detects that the push plate trolley 2 reaches a cutting area, the controller controls the gypsum board conveyor to stop according to a first distance signal output by the push plate ranging sensor 1, and after stopping, the push plate ranging sensor 1 detects and outputs a second distance signal, and then the controller controls the sliding table cutter 3 to move to the position flush with the push plate trolley 2 according to the second distance signal, so that edge sealing belts between the two gypsum boards are cut off, the edge sealing belts are cut off centrally, the cutting precision of the edge sealing belts is improved, and longer tail breakage of the edge sealing belts is avoided.
The existing common automatic cutting method generally uses a sensor on the sliding table cutter 3 to detect a gap between two gypsum boards in the moving process of the sliding table cutter 3, and when the gap is detected, the sliding table cutter 3 stops moving and controls the cutter 352 to act to cut off the edge sealing tape.
However, in the conventional automatic cutting method, since the sensor moves along with the sliding table cutter 3, the sliding table cutter 3 stops moving after detecting the gap, and at this time, the cutter 352 is located at one side of the gap (the side of the sliding table cutter 3 moving towards the gap) so that the cutting at this time can result in a longer edge sealing band at one end of the two plasterboards, and a shorter edge sealing band at the other end, thereby resulting in uneven edge sealing.
Compared with the existing automatic cutting method, the automatic cutting method of the embodiment can measure whether the position (the first distance signal) of the push plate trolley 2 for fixing and separating two gypsum boards reaches the cutting area, so that the position (the second distance signal) of the gap between the two gypsum boards is detected after the vehicle is stopped, and according to the detection of the position of the gap, the sliding table cutter 3 is controlled to move to the middle of the gap and cut off, so that the edge sealing bands of the two gypsum boards are even and short in broken ends, and the edge sealing of the gypsum boards is tidier.
Wherein the (gypsum board) pushing plate trolley 2 is a belt upper partition board equidistantly arranged on the belt conveyor.
The sliding table cutter 3 is controlled to move by the controller according to the second distance signal, and in order to ensure that the sliding table cutter 3 can precisely move to a position flush with the push plate trolley 2, the following preferred embodiment is provided.
As shown in fig. 2, the slipway cutter 3 is realized by a motor 31, a screw pair 32, a rail portion 33, a slipway portion 34 and a cutting portion 35, the rail portion 33 is mounted on a side frame of the plasterboard conveyor, the screw pair 32 is rotatably provided on an end wall of the rail portion 33, the slipway portion 34 is provided on the screw pair 32 and slides on the rail portion 33, and the cutting portion 35 is provided on the slipway portion 34;
The motor 31 is controlled by a controller to rotate the screw pair 32 and drive the slide table portion 34 and the cutting portion 35 to horizontally slide in parallel with the direction of gypsum board conveyance.
Specifically, the motor 31 is a stepping motor, and the controller controls the rotation angle of the motor 31 (stepping motor) to control the rotation number of the screw pair 32, so as to precisely control the sliding distance of the sliding table part 34, and the sliding table part 34 can drive the cutting part 35 to move to the position flush with the push plate trolley 2, so that the centering average cutting-off is realized.
The sliding table cutter 3 adopts the stepping motor to drive, and has the advantages of high precision, realization of open loop control and simple control program.
The following preferred embodiment is provided in order to enable the cutting part 35 to be accurately moved to be flush with the push plate dolly 2 by changing the distance between the cutting part 35 and the push plate measuring sensor when the slide part 34 of the slide cutter 3 is moved on the rail part 33.
As shown in fig. 2, the distance between the end of the rail portion 33 and the push plate ranging sensor 1 is fixed, and when the slide table portion 34 moves on the rail portion 33, the distance between the cutting portion 35 and the push plate ranging sensor 1 is changed;
Wherein, when the cutting part 35 moves such that the distance between it and the push plate ranging sensor 1 is equal to the distance value fed back by the second distance signal, the slide table part 34 is stopped and the cutting part 35 operates.
Specifically, since the distance between the end of the rail portion 33 (the end away from the push plate ranging sensor 1) and the push plate ranging sensor 1 is fixed to a known value, the moving distance of the controller control slide portion 34 is controllable;
the distance moved by the slide table portion 34 is determined based on the difference between the fixed distance between the end of the rail portion 33 and the push plate distance measuring sensor 1 and the measured distance (distance value fed back by the second distance signal) of the push plate dolly 2.
The controller inputs a movement command according to the difference value, and directly drives the cutting part 35 to move by a corresponding distance through the stepping motor, so that accurate cutting of the edge sealing belt is realized.
However, since the starting frequency of the stepper motor is not high (step-out is avoided), the starting frequency and the running frequency of the stepper motor are greatly different, and the rotating speed of the stepper motor is controlled by the input pulse frequency, the stepper motor cannot achieve higher dynamic response. Accordingly, the following preferred embodiments are provided.
As shown in fig. 3, the distance between the cutting part 35 and the push plate ranging sensor 1 is detected in real time and a third distance signal is output, and the third distance signal is fed back to the controller in real time;
the controller controls the slide table section 34 to finely adjust according to the difference between the feedback distance value of the third distance signal and the feedback distance value of the second distance signal.
At this time, the motor 31 may adopt a servo motor, the motor 31 (servo motor) controls the screw pair 32 to rotate, the dynamic response is faster, and the feedback of the third distance signal forms a closed-loop control, so that the precision is higher.
Specifically, when the cutting part 35 moves along with the sliding table part 34, the distance between the cutting part 35 and the push plate ranging sensor 1, namely, a third distance signal is measured in real time, and the controller compares the distance value fed back by the third distance signal with the distance value fed back by the second distance signal to obtain a difference value between the two;
The controller controls the motor 31 (servo motor) to rapidly rotate the screw pair 32 according to the feedback distance difference between the third distance signal and the second distance signal, thereby rapidly driving the slide table part 34 and the cutting part 35 to move until the feedback distance values of the third distance signal and the second distance signal are equal;
at this time, the cutting portion 35 is flush with the push plate dolly 2, thereby enabling a quick and accurate realization of cutting off the edge sealing tape in the middle.
Since the push plate ranging sensor 1 can only linearly measure the distance of the push plate trolley 2, and cannot simultaneously measure the distance between the push plate trolley 2 and the cutting part 35, an additional sensor is required to detect the distance between the cutting part 35 and the push plate ranging sensor 1, and the following preferred embodiments are provided.
As shown in fig. 3, the distance between the cutting part 35 and the push plate ranging sensor 1 is achieved by a cutter ranging sensor 353, and the cutter ranging sensor 353 is provided on the cutting part 35;
Wherein, the perception terminal surface of cutter range sensor 353 flushes with the lateral wall that cutting part 35 is close to push pedal range sensor 1, and the thickness of cutting part 35 equals the thickness of push pedal dolly 2.
The cutter ranging sensor 353 provided on the cutting part 35 can detect the distance between the cutting part 35 and the push plate ranging sensor 1 to obtain a third distance signal.
Since the sensing end surface of the cutter ranging sensor 353 is flush with the side wall of the cutting part 35 close to the push plate ranging sensor 1, the cutter ranging sensor 353 actually measures the distance from the surface of the cutting part 35 (the cutter 352 therein) to the push plate ranging sensor 1, so that the cutting part 35 (the cutter 352 therein) is flush with the push plate trolley 2 when the feedback distance value of the third distance signal is equal to the feedback distance value of the second distance signal.
And the thickness of the cutting part 35 (of which the cutter 352) is equal to that of the push plate trolley 2, the cutting part 35 (of which the blade of the cutter 352) is aligned in the middle of the gap between the two plasterboards, so that the edge sealing tape between the two plasterboards can be cut off centrally by the cutting part 35.
Since the push plate dolly 2 and the cutting part 35 are not at the same height, the cutter ranging sensor 353 and the push plate ranging sensor 1 are not at the same height, but the cutter ranging sensor 353 and the push plate ranging sensor 1 need to measure the horizontal distance between the cutting part 35 and the push plate ranging sensor 1 and the horizontal distance between the push plate dolly 2 and the push plate ranging sensor 1, respectively. Accordingly, the following preferred embodiments are provided.
As shown in fig. 3, the push plate ranging sensor 1 is arranged on a downstream frame of the gypsum board conveyor through a bracket, and the distance between the cutter ranging sensor 353 and the push plate ranging sensor 1 is measured through the reference panel 11;
wherein, the reference panel 11 sets up on the support of push pedal range sensor 1, and reference panel 11 flushes with the perception terminal surface of push pedal range sensor 1.
When the sensing end surfaces of the reference panel 11 and the push plate ranging sensor 1 coincide, the distance between the cutter ranging sensor 353 and the reference panel 11 is detected as the horizontal distance between the cutter ranging sensor 353 and the push plate ranging sensor 1, so that the distance between the push plate ranging sensor 1 and the cutting part 35 is reflected.
Similarly, a cutter ranging sensor 353 coplanar with the sensing end surface of the push plate ranging sensor 1 can be arranged at the position (bracket) of the push plate ranging sensor 1, so that the position of the cutting part 35 can be measured.
This method may be implemented without the reference panel 11, but the cutting part 35 needs to be telescopically moved during the cutting process, which may cause the loss of the measurement signal of the cutting part 35 (the cutter 352 therein) by the cutter ranging sensor 353 (the cutter 352 of the cutting part 35 is moved out of the sensing area) to malfunction; of course, the "malfunction prevention procedure" can be solved by a procedure adjustment to not process the third distance signal of the cutter ranging sensor 353 during cutting, more complicated than the method measured by the reference panel 11.
The edge banding cutting between two gypsum boards requires that the gap between two gypsum boards be moved to the cutting area by the gypsum board conveyor for cutting 352, and because the gypsum board conveyor is difficult to keep the gypsum boards to stop only at the same position, the accurate cutting in the middle can be realized in the position that needs the gypsum board to stay in a certain range. Accordingly, the following preferred embodiments are provided.
As shown in fig. 2, the cutting area is realized by the distance between the push plate ranging sensor 1 and the push plate trolley 2, and specifically includes:
At the beginning of each cutting-off period, if the push plate distance measuring sensor 1 detects that the distance between the push plate distance measuring sensor 1 and the push plate trolley 2 is larger than the distance from the push plate distance measuring sensor 1 to the end part of the track part 33, which is far away from the push plate distance measuring sensor 1, no signal is output;
Outputting a first distance signal if the push plate distance measuring sensor 1 detects that the distance between the push plate distance measuring sensor 1 and the push plate trolley 2 is smaller than the distance from the push plate distance measuring sensor 1 to the end part of the track part 33, which is far away from the push plate distance measuring sensor 1;
In each cutting cycle, after the cutting unit 35 is operated, the cycle is ended until the detection value of the push plate distance measuring sensor 1 is suddenly increased, and the next cycle is started.
When the distance between the pushing plate distance measuring sensor 1 and the pushing plate trolley 2 is detected to be larger than the distance from the pushing plate distance measuring sensor 1 to the end of the track portion 33 far away from the pushing plate distance measuring sensor 1, a gap between two gypsum boards does not enter the track portion 33 section at this time, namely, the gap is positioned at a position where the sliding table portion 34 and the cutter 352 cannot move.
When the distance between the pushing plate distance measuring sensor 1 and the pushing plate trolley 2 is detected to be smaller than the distance between the pushing plate distance measuring sensor 1 and the end part of the track part 33, which is far away from the pushing plate distance measuring sensor 1, a distance signal is output once, a gap representing two plasterboards is located in the track part 33 section, and after the controller controls the plasterboard conveyor to stop moving, the two plasterboards stop moving and the gap between the two plasterboards is located in the track part 33 section.
Namely, the position located in the section of the track portion 33 is a cutting area, and after the cutting is completed, the current cycle is ended; and when the push plate ranging sensor 1 detects a value larger than the distance from the push plate ranging sensor 1 to the end of the track portion 33 far away from the push plate ranging sensor 1, the next cycle is started, i.e. the record of the cutting times can be realized.
An intermittent period exists between two adjacent periods, namely, detection: the distance from the push plate ranging sensor 1 to the push plate trolley 2 is continuously smaller (the distance is decreased) than the distance from the push plate ranging sensor 1 to the end of the track part 33 away from the push plate ranging sensor 1 until the distance from the push plate ranging sensor 1 to the push plate trolley 2 is suddenly larger than the distance from the push plate ranging sensor 1 to the end of the track part 33 away from the push plate ranging sensor 1. This process is the return process of the pusher carriage 2 on the belt conveyor (existing structure) from the bottom up.
Through the trigger threshold value of presetting push pedal range sensor 1 output, realize the division of cutting area, both avoided the gap between two gypsum boards to surpass the scope that slip table cutter 3 can work, also need not other sensors to detect spacingly, the cost is reduced and the procedure setting degree of difficulty is also lower.
The cutting portion 35 of the slipway cutter 3 needs to be stretched to complete cutting and resetting when cutting the edge sealing tape, as follows.

In the process of cutting the edge sealing tape under the control of the controller, the air cylinder 351 needs to push the cutter 352 to a preset position to ensure that the cutter 352 cuts off the edge sealing tape completely, and the cutter 352 is placed in a gap between two gypsum boards. And after cutting, the shorter the distance that the cutter 352 continues to be pushed by the cylinder 351, the shorter the time the cutting part 35 acts, so that the cutting efficiency can be improved, and the production efficiency can be improved.
Therefore, it is necessary to stop the cylinder 351 in time to continue pushing the cutter 352 to move after the cutter 352 cuts the edge sealing tape, and thus, in order to enable the cutter 352 to completely cut the edge sealing tape each time cutting and to stop in time after cutting, the following preferred embodiments are provided.

after the edge sealing tape is cut off by the cutter 352, the limit sensor 354 is pushed to the lower part of the gypsum board by the air cylinder 351;
the limit sensor 354 senses the plasterboard and outputs a reset signal to the controller;
the controller controls the cylinder 351 to reset.
Since the cylinder 351 is located below the plasterboard, the cutter 352 protrudes above the moving end of the cylinder 351 to enable cutting of the edge banding band above.
And cutter 352 stands out spacing sensor 354, then can be after cutter 352 cuts off the banding area, spacing sensor 354 detects the gypsum board to feed back to the controller, make the controller can in time control cylinder 351 stop when guaranteeing to cut off the banding area.
The cylinder 351 always operates in the gypsum board production environment, and the cylinder 351 acts on the production line for a long time, dust falling on a cylinder rod can be continuously pushed and accumulated at a cylinder opening of the cylinder 351, so that the situation that the reset is not in place possibly exists in the long-term use process, the cutter 352 affects the transportation of the gypsum board, and the cutter 352 damages the gypsum board or the gypsum board damages the cutter 352 in the transportation process.
Accordingly, in order to avoid the occurrence of incomplete resetting of the cutter 352 to start the gypsum board conveyor for conveying gypsum board, the following preferred embodiments are provided.

after the controller receives the reset signal output by the limit sensor 354, the controller controls the cylinder 351 to reset;
The reset sensor 355 moves back along with the moving end of the air cylinder 351, and when the reset sensor 355 senses the fixed end of the air cylinder 351, a reset completion signal is output to the controller;
The controller controls the gypsum board conveyor to start according to the reset completion signal.
Specifically, the reset sensor 355 can sense the fixed end of the air cylinder 351 after the moving end of the air cylinder 351 is completely reset, and when the moving end of the air cylinder 351 is separated from the fixed end beyond a certain position, the sensing end face of the reset sensor 355 loses the sense of the fixed end of the air cylinder 351, so that the condition that the moving end of the air cylinder 351 is not completely reset is judged, the reset sensor 355 does not output a reset signal at this time, the controller cannot control the start of the gypsum board conveyor, the reset self-checking of the air cylinder 351 can be realized, and safety accidents caused by the start of the gypsum board conveyor when the air cylinder 351 is not reset can be avoided.
