Description

Technical Field

[0001] The present invention relates to the technical field of gypsum boards, and in particular to an intelligent board output control system and a control method for a gypsum board dryer. Background Art

[0002] During the gypsum board production process, when the wet gypsum board reaches the dryer outlet after drying, since the dryer has 10 layers of conveying, in order to ensure the normal conveying of the board, the dryer can only put the board in a single layer at a time.

[0003] Most of the existing technologies use the board discharging control system to discharge boards in a first-in-first-out manner, so most of them discharge boards in sequence in an existing cruising manner. However, the drying capacity of each drying chamber in the dryer is different, and the dryer can only place boards on one layer. Therefore, if the boards are placed in a cruising manner in a first-in-first-out manner, boards will be piled up at the exit of a drying chamber on a certain layer. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent board discharge control system and control method for a gypsum board dryer, so as to solve the technical problem that in the prior art, boards are discharged in a first-in-first-out manner, which may cause the boards to pile up at the outlet of a drying chamber on a certain layer.

[0005] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0006] An intelligent board discharging control system for a gypsum board drying machine, comprising:

[0007] A plate position detection component is installed at the plate exit position of each layer of the dryer, and the plate position detection component is used to monitor the number of plates transmitted to the dryer exit position;

[0008] A board-outlet scanning and receiving assembly is installed at the outlet side of the dryer, and the board-outlet scanning and receiving assembly can adjust its height to different outlets of the dryer to receive the dried gypsum board sheets outputted from different outlets of the dryer;

[0009] A control system, which is respectively connected to the board position detection component and the board output scanning and receiving component for communication, and the control system adjusts the scanning height of the board output scanning and receiving component according to the monitoring result of the board position detection component;

[0010] Among them, the control system sets the scanning priority based on the number of boards monitored by the board position detection component, the board output waiting time of different outlets of the dryer, and the distance between the outlet of the dryer and the current position of the board output scanning and receiving component, so that the board output scanning and receiving component adjusts its scanning height in sequence according to the scanning priority to sequentially output the dried gypsum board boards.

[0011] As a preferred solution of the present invention, when each layer outlet of the dryer is waiting for the board to be discharged, the control system controls the board discharge scanning and receiving components to move to different layer outlets of the dryer according to the set initial scanning sequence according to the system board discharge mode;

[0012] Among them, the system board output mode uses the order in which the gypsum boards enter the dryer as the initial scanning order of the board output scanning and receiving component.

[0013] As a preferred solution of the present invention, the order in which the gypsum boards enter the dryer is intermittent, and the wet gypsum boards enter the dryer in sequence in a manner of one drying layer interval, so that the ends of the dried gypsum boards received by the board-exit scanning and receiving component do not overlap;

[0014] The control system is connected to a host computer, which adjusts the heating efficiency of the gypsum board dryer and the board placement interval period based on the gypsum board scrap rate received by the board output scanning and receiving component, so that the board output scanning and receiving component can transfer the gypsum boards at each layer outlet of the gypsum board dryer in time.

[0015] As a preferred solution of the present invention, the control system includes a real-time statistical module for the number of boards output, a real-time statistical module for the board output waiting time, a real-time statistical module for the scanning distance, and a scanning sequence setting module;

[0016] The real-time statistical module for the number of gypsum boards output is used to calculate the number of gypsum boards at each outlet of the dryer;

[0017] The real-time statistical module for board exit waiting time is used to count the maximum waiting time of the gypsum boards at each exit position of the dryer;

[0018] The scanning distance real-time statistics module is used to count the distance between the exit position of each layer of the dryer and the current position of the plate-exit scanning receiving component;

[0019] The scanning sequence setting module determines the scanning sequence of the outgoing board scanning receiving component based on the statistical results of the outgoing board quantity real-time statistical module, the outgoing board waiting time real-time statistical module, and the scanning distance real-time statistical module.

[0020] As a preferred solution of the present invention, when the scanning sequence setting module determines the scanning sequence of the board-outlet scanning receiving component, the number of gypsum boards at each outlet position of the dryer calculated by the real-time statistical module of the number of outgoing boards is taken as the first priority, and the scanning sequence of the board-outlet scanning receiving component is positively correlated with the number of gypsum boards at each outlet position of the dryer;

[0021] The board-outlet waiting time of each layer of the dryer, which is counted by the real-time board-outlet waiting time counting module, is the second priority;

[0022] And the distance between each layer outlet of the dryer and the current position of the plate-out scanning receiving component counted by the scanning distance real-time statistical module is the third priority.

[0023] As a preferred solution of the present invention, when the number of gypsum boards at each layer outlet position of the dryer is the same and the number of outlets of the dryer with the same board output priority is at least two, the control system determines the board output waiting time of multiple outlets of the dryer with the same board output priority based on the time point corresponding to the first gypsum board appearing at the outlet of the dryer with the same board output priority monitored by the board position detection component;

[0024] The longer the waiting time for the board to be discharged is, the earlier the scanning order of the board discharge scanning and receiving component for the outlet of the dryer is;

[0025] The shorter the waiting time for the board to be discharged, the later the priority of the scanning sequence of the board discharge scanning and receiving component for the outlet of the dryer is.

[0026] As a preferred solution of the present invention, when the number of gypsum boards at each outlet of the dryer is the same and the waiting time for the boards to be discharged at each outlet of the dryer is the same, the waiting time for the boards to be discharged is compared with the set safety time. If the waiting time for the boards to be discharged is less than the set safety time, the boards are placed at the outlet of the dryer in sequence according to the moving direction of the board discharge scanning and receiving component.

[0027] If the waiting time for the board to be discharged is greater than or equal to the set safety time, the smaller the distance between each floor exit of the dryer and the current position of the board discharge scanning and receiving component, the higher the scanning order priority of the board discharge scanning and receiving component for the exit of the dryer;

[0028] The greater the distance between each layer outlet of the dryer and the current position of the plate-out scanning and receiving component, the later the scanning order priority of the plate-out scanning and receiving component for the outlet of the dryer is.

[0029] In order to solve the above technical problems, the present invention also provides a control method based on the intelligent board output control system of the gypsum board dryer, comprising the following steps:

[0030] Step 100, determining the board feeding sequence of the gypsum board drying machine, and performing patrol scanning on the board output scanning receiving component according to the board feeding sequence;

[0031] Step 200, simultaneously monitoring the number of boards corresponding to all outlets of the gypsum board dryer, and determining the scanning priority of the board-outlet scanning receiving component based on the number of boards staying at the outlets, the board-outlet waiting time, and the distance between the outlets and the current position of the board-outlet scanning receiving component;

[0032] Step 300: The board-exit scanning and receiving components are moved to the corresponding exit positions of the gypsum board dryer in sequence according to the scanning priority.

[0033] As a preferred embodiment of the present invention, the board feeding sequence of the gypsum board dryer is intermittent board feeding, and there is an interval drying layer between the drying layers of two gypsum board dryers that feed the boards successively;

[0034] When the outgoing board scanning and receiving component performs patrol scanning according to the incoming board sequence, it performs reciprocating cyclic scanning in an interval patrol mode.

[0035] As a preferred solution of the present invention, in step 200, the board exit waiting time is the period between the time point when the board position detection component detects the first gypsum board appears at each outlet of the gypsum board dryer and the current time point;

[0036] The number of plates staying at the exit is the first priority of the scanning sequence of the exit plate scanning receiving component;

[0037] The board-out waiting time is the second priority of the scanning sequence of the board-out scanning receiving component;

[0038] The distance between the exit for waiting for the board to be output and the current position of the board output scanning and receiving component is the third priority of the scanning sequence of the board output scanning and receiving component.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] When the present invention controls the board output of the multi-layer outlets of the dryer, the board output waiting time of each layer of the outlet is used to set the order of scanning and outputting the boards, wherein the number of boards to be output is the first priority. When the number of boards to be output at the outlet is relatively large, the boards need to be output in time to avoid disorderly boards or accumulation of boards at the outlet caused by subsequent confusion in placing boards. The board output waiting time is the second priority, and the distance between the outlet waiting for boards to be output and the current position of the board output scanning and receiving component is the third priority, thereby avoiding the problem of overdrying of gypsum boards.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0047] like Figure 1 As shown, the present invention provides an intelligent board output control system for a gypsum board drying machine, comprising a board position detection component 1, a board output scanning and receiving component 2 and a control system 3.

[0048] The board position detection component 1 is installed at the board exit position of each layer of the dryer. The board position detection component 1 is used to monitor the number of boards transmitted to the dryer exit position.

[0049] The board-exit scanning and receiving component 2 is installed at the outlet side of the dryer. The board-exit scanning and receiving component 2 can adjust its height to different outlets of the dryer to receive the dried gypsum board panels output from different outlets of the dryer.

[0050] The control system 3 is respectively connected to the board position detection component 1 and the outgoing board scanning and receiving component 2 for communication. The control system 3 adjusts the scanning height of the outgoing board scanning and receiving component 2 according to the monitoring result of the board position detection component 1 .

[0051] Among them, the control system 3 sets the scanning priority based on the number of boards monitored by the board position detection component 1, the board output waiting time of different outlets of the dryer, and the distance between the outlet of the dryer and the current position of the board output scanning and receiving component 2, so that the board output scanning and receiving component 2 adjusts its scanning height in sequence according to the scanning priority to sequentially output the dried gypsum board boards.

[0052] In order to avoid the accumulation of boards in a certain layer of the drying chamber, the present embodiment installs a board position detection component 1 at the outlet of the dryer to detect the number of boards at the outlet of the dryer in real time and determine their accumulation status. The number of boards at each outlet of the dryer, the board waiting time at each outlet of the dryer, and the distance between the outlet of the dryer and the current position of the board scanning and receiving component 2 are used to select the number of boards to be placed, so as to achieve optimal board placement and avoid disordered board placement or accumulation of boards at the outlet.

[0053] Specifically, the operation sequence of this embodiment for sequentially discharging the dried gypsum board sheets is as follows:

[0054] First, count the number of gypsum board sheets at the outlets of all layers of the dryer, and then perform the board discharge operation in order of the number of sheets. When the number of sheets at a certain outlet is relatively large, the board discharge priority of this outlet is relatively high; when the number of sheets at a certain outlet is relatively small, the board discharge priority of this outlet is relatively low.

[0055] When there are more than two export plates with the same number, the plates at the above export positions will be placed in order according to the plate waiting time of the two or more export positions, among which the plate with a longer waiting time has a higher priority, while the plate with a shorter waiting time has a lower priority.

[0056] Furthermore, when the waiting time for the plates to be discharged from more than two exit positions is the same, the plates at the multiple exit positions are placed in sequence according to the distance between the exit of the dryer waiting for the plates to be discharged and the current position of the plate discharge scanning and receiving component 2.

[0057] Among them, when there are no boards at all the layer outlets of the dryer and each layer outlet of the dryer is waiting for boards to be output, the control system 3 controls the board output scanning and receiving component 2 according to the system board output mode and moves it to different layer outlets of the dryer according to the set initial scanning sequence.

[0058] The system board output mode uses the order in which the gypsum boards enter the dryer as the initial scanning order of the board output scanning and receiving component 2. Furthermore, the order in which the gypsum boards enter the dryer is intermittent, and the wet gypsum boards enter the dryer in sequence with an interval of one drying layer, so that the ends of the dried gypsum board panels received by the board scanning and receiving component 2 do not overlap.

[0059] For example, the order in which gypsum boards enter the dryer is: 10th layer → 8th layer → 6th layer → 4th layer → 2nd layer → 1st layer → 3rd layer → 5th layer → 7th layer → 9th layer → 10th layer. When there are no boards on any layer during the first operation, the board output scanning receiving component 2 performs a cyclic scanning in the order of 10th layer → 8th layer → 6th layer → 4th layer → 2nd layer → 1st layer → 3rd layer → 5th layer → 7th layer → 9th layer → 10th layer.

[0060] The board position detection component 1 monitors in real time the number of boards waiting to be output at all layer exits of the dryer, and adjusts the board output scanning order of the board output scanning and receiving component 2 based on the number of boards. At this time, the scanning and receiving component 2 no longer works according to the system board output mode, but adjusts the scanning and output mode according to the specific board output priority order.

[0061] Furthermore, the control system 3 is connected to a host computer 4, which adjusts the heating efficiency of the gypsum board dryer and the board placement interval based on the gypsum board scrap rate received by the board output scanning and receiving component 2, so that the board output scanning and receiving component 2 can transfer the gypsum boards at each layer outlet of the gypsum board dryer in time.

[0062] In order to set the scanning sequence of the output board scanning receiving component 2, the control system 3 includes a real-time statistical module 31 for the number of output boards, a real-time statistical module 32 for the waiting time for output boards, a real-time statistical module 33 for the scanning distance, and a scanning sequence setting module 34.

[0063] The real-time board output counting module 31 is used to calculate the number of gypsum boards at each outlet of the dryer.

[0064] The real-time statistical module 32 for board exit waiting time is used to count the maximum waiting time of the gypsum boards at each exit position of the dryer.

[0065] The scanning distance real-time statistics module 33 is used to count the distance between the exit position of each layer of the dryer and the current position of the board exit scanning receiving component 2.

[0066] The scanning sequence setting module 34 determines the scanning sequence of the outgoing board scanning receiving component 2 based on the statistical results of the outgoing board quantity real-time statistical module 31 , the outgoing board waiting time real-time statistical module 32 , and the scanning distance real-time statistical module 33 .

[0067] When the scanning sequence setting module 34 determines the scanning sequence of the board output scanning receiving component 2, the number of gypsum boards at each outlet position of the dryer calculated by the real-time board output quantity statistics module 31 is taken as the first priority, and the scanning order of the board output scanning receiving component 2 is positively correlated with the number of gypsum boards at each outlet position of the dryer.

[0068] The board-outlet waiting time at each layer of the dryer outlet counted by the board-outlet waiting time real-time counting module 32 is the second priority.

[0069] The distance between each layer outlet of the dryer and the current position of the board-exit scanning receiving component 2 counted by the scanning distance real-time counting module 33 is the third priority.

[0070] The specific setting method of the scanning sequence of the plate-out scanning receiving component 2 for the dryer with 10 drying chambers is as follows:

[0071] Assuming that the number of boards at the exit positions of the 10-layer drying chambers is different, the board output priority is set according to the number of gypsum boards at the exit positions of each layer of the dryer. The larger the number of gypsum boards, the higher the board output priority, and the smaller the number of gypsum boards, the lower the board output priority. The board output scanning and receiving component 2 outputs the boards in sequence according to the board output priority set according to the number of gypsum boards.

[0072] Assuming that the exit positions of the 10-layer drying chamber have the same number of plate outputs, the scanning order of the exit positions is: first determine the waiting time for plate output in the exit positions with the same number of plate outputs. The waiting time for plate output is specifically the time for the plate closest to the exit to move to this position and wait for plate output. The exit with a larger waiting time for plate output has an earlier scanning order, and the exit with a smaller waiting time for plate output has a later scanning order.

[0073] That is, when the number of gypsum boards at each outlet of the dryer is the same, and the number of outlets of the dryer with the same board output priority is at least two, the control system 3 determines the waiting time for multiple outlets of the dryer with the same board output priority based on the time point corresponding to the appearance of the first gypsum board at the outlet of the dryer with the same board output priority monitored by the board position detection component 1.

[0074] The longer the waiting time for the board output is, the earlier the scanning order of the board output scanning and receiving component 2 for the outlet of the dryer is.

[0075] The shorter the waiting time for the board output, the later the scanning order priority of the board output scanning and receiving component 2 for the outlet of the dryer.

[0076] Furthermore, assuming that at least two exit positions of the 10-layer drying room have the same number of plate output boards, and the waiting time for the gypsum boards at the exit positions is also the same, the scanning order of the plates is determined according to the specific value of the waiting time for the plates to be output. The specific implementation method is as follows:

[0077] When the number of gypsum boards at each exit of the dryer is the same and the waiting time for the boards to be discharged at each exit of the dryer is the same, the waiting time for the boards to be discharged is compared with the set safety time. If the waiting time for the boards to be discharged is less than the set safety time, the boards are placed at the exit of the dryer in sequence according to the moving direction of the board discharge scanning receiving component 2.

[0078] If the dryer outlet is located on both sides of the board output scanning and receiving component 2 at this time, the boards are placed in sequence in both directions according to the moving direction of the board output scanning and receiving component 2. If the dryer outlet is located on the same side of the board output scanning and receiving component 2 at this time, the boards are placed in sequence in one direction according to the moving direction of the board output scanning and receiving component 2.

[0079] If the waiting time for the board to be discharged is greater than or equal to the set safety time, the smaller the distance between each floor exit of the dryer and the current position of the board discharge scanning and receiving component 2, the higher the scanning order priority of the board discharge scanning and receiving component 2 for the exit of the dryer.

[0080] The greater the distance between each floor exit of the dryer and the current position of the outgoing board scanning and receiving component 2 , the later the scanning sequence priority of the outgoing board scanning and receiving component 2 for the exit of the dryer is.

[0081] That is, according to the waiting time for board output, the boards at the gypsum board outlet can be divided into boards that have been output within the safe time range and boards that have been burned beyond the safe time range. Among them, when the waiting time for the gypsum boards at the exit position is the same and both are within the safe time range, the boards are placed in sequence according to the moving direction of the board output scanning and receiving component 2, regardless of the distance between each layer exit and the current position of the board output scanning and receiving component 2.

[0082] When the waiting time for the gypsum boards at the exit position is the same and exceeds the safe time range, at this time, the board corresponding to the exit position is an over-fired board whose drying time exceeds the set time. The smaller the distance between each layer of the dryer exit and the current position of the exit scanning and receiving component 2, the higher the scanning order priority of the exit scanning and receiving component 2 for the dryer, so as to reduce the heating time of the over-fired board and reduce the scrap rate.

[0083] In addition, the present invention also provides a control method for an intelligent board discharging control system of a gypsum board drying machine, which is characterized by comprising the following steps:

[0084] Step 100, determine the board feeding sequence of the gypsum board drying machine, and perform patrol scanning on the board output scanning receiving component according to the board feeding sequence.

[0085] The board feeding sequence of the gypsum board dryer is intermittent feeding, and there is an interval drying layer between the drying layers of two gypsum board dryers that feed the boards one after another.

[0086] When the outgoing board scanning receiving component performs patrol scanning according to the incoming board sequence, it performs reciprocating cyclic scanning in an interval patrol mode.

[0087] Step 200, simultaneously monitoring the number of boards corresponding to all outlets of the gypsum board dryer, and determining the scanning priority of the board-exit scanning receiving component based on the number of boards staying at the outlets, the board-exit waiting time, and the distance between the outlets and the current position of the board-exit scanning receiving component;

[0088] Step 300: The board-exit scanning receiving component moves to the corresponding exit position of the gypsum board dryer in sequence according to the scanning priority.

[0089] In step 200, the board exit waiting time is the period between the time point when the board position detection component detects the first gypsum board appears at each outlet of the gypsum board dryer and the current time point;

[0090] Among them, the number of plates staying at the exit is the first priority of the scanning sequence of the plate-exit scanning receiving component;

[0091] The board-out waiting time is the second priority of the scanning sequence of the board-out scanning receiving component;

[0092] The distance between the exit for waiting for the board to be output and the current position of the board output scanning and receiving component is the third priority of the scanning sequence of the board output scanning and receiving component.

[0093] When the present embodiment controls the board discharge from the multi-layer outlets of the dryer, the order of scanning and discharging boards is set according to the number of boards to be discharged from each outlet of the dryer, the board discharge waiting time of each outlet, and the distance between the outlet waiting for board discharge and the current position of the board discharge scanning and receiving component. Among them, the number of boards to be discharged is the first priority. When the number of boards to be discharged from the outlet is relatively large, the boards need to be discharged in time to avoid disorder or accumulation of boards at the outlet caused by subsequent confusion in placing boards. When the number of boards to be discharged from a certain outlet is the same, but the board discharge waiting time required by the outlet is different, and the board discharge waiting time required for one of the outlets is relatively long, the boards need to be discharged in time to avoid over-drying of the boards.

[0094] Most importantly, when the number of plates to be discharged from a certain outlet is the same and the waiting time for the plates to be discharged from the outlet is the same, the scanning order of the plate discharge scanning and receiving component is adjusted according to the comparison result between the plate discharge waiting time and the safety time range. When the plate discharge waiting time is less than the safety time range, the plates are placed at the outlet of the dryer in sequence according to the moving direction of the plate discharge scanning and receiving component. When the plate discharge waiting time is greater than the safety time range, the scanning order priority of the plate discharge scanning and receiving component for the outlet of the dryer is adjusted according to the distance between each layer of the outlet of the dryer and the current position of the plate discharge scanning and receiving component. The smaller the distance between each layer of the outlet of the dryer and the current position of the plate discharge scanning and receiving component, the higher the scanning order priority of the plate discharge scanning and receiving component for the outlet of the dryer is, so as to reduce the heating time of the over-fired plates and reduce the scrap rate.
