and S12, adjusting the first conveying speed and/or the conveying speeds of the other plate-out sections except the Nth plate-out section in the plate-out area according to the first detection result.

In an exemplary embodiment of the present application, a specific number of the plurality of outgoing board segments may be defined according to a requirement, and is not limited herein, for example, N ═ 4 may be taken, that is, the plurality of outgoing board segments may include: a first plate outlet section 31, a second plate outlet section 32, a third plate outlet section 33 and a fourth plate outlet section 34, wherein the first plate outlet section 31 is connected with the closed drying zone, and the fourth plate outlet section 34 can be used as the tail end of the plate outlet zone 3. The first plate outlet section 31, the second plate outlet section 32, the third plate outlet section 33 and the fourth plate outlet section 34 will be described as examples in the following.

In the exemplary embodiment of the present application, whether there is a plate on the first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33, and the fourth plate discharging section 34 may be detected in real time, and the speed of each of the first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33, and the fourth plate discharging section 34 may be detected, so as to adjust the conveying speed of each plate discharging section in real time according to the determination result.

In the exemplary embodiment of the present application, the fourth board outlet section 34 is the board outlet section that is most closely related to the subsequent equipment process of the dryer, and whether there is a board and the conveying speed thereof are directly related to the board redundancy degree of the whole board outlet area 3, and in turn, whether there is a board in the fourth board outlet section 34 and the conveying speed thereof can be used as the main monitoring object.

In an exemplary embodiment of the present application, the control of the first tapping section 31, the second tapping section 32, the third tapping section 33 and the fourth tapping section 34 may include four schemes:

according to the first scheme, the conveying speeds of the first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33 and the fourth plate discharging section 34 are controlled according to whether plates exist on the fourth plate discharging section 34 and the relation between the running speed of the fourth plate discharging section 34 and the conveying speeds of the first plate discharging section 31, the second plate discharging section 32 and the third plate discharging section 33 (the first plate discharging section 31, the second plate discharging section 32 and the third plate discharging section 33 can be collectively called other plate discharging sections);

controlling the conveying speeds of the first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33 and the fourth plate discharging section 34 only according to whether plates exist on the first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33 and the fourth plate discharging section 34;

and thirdly, controlling the conveying speeds of the first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33 and the fourth plate discharging section 34 according to whether plates exist on the fourth plate discharging section 34, whether plates exist on other plate discharging sections and the relation between the operating speed of the fourth plate discharging section 34 and the conveying speeds of other plate discharging sections.

Scheme one can be first detailed as follows:

in the exemplary embodiment of the present application, after determining whether there is a plate on the fourth plate discharging section 34 and the relationship between the running speed of the fourth plate discharging section 34 and the conveying speeds of the other plate discharging sections, only the conveying speed of the fourth plate discharging section 34 may be controlled, only the conveying speeds of the first plate discharging section 31, the second plate discharging section 32, and the third plate discharging section 33 may be controlled, and the conveying speeds of the fourth plate discharging section 34 and the other plate discharging sections may be controlled at the same time. Wherein the conveying speed of any one or more of the first plate discharging section 31, the second plate discharging section 32 and the third plate discharging section 33 can be controlled simultaneously.

1. When the conveyance speed of only the fourth outgoing lane 34 (i.e., the first conveyance speed) is controlled:

In the exemplary embodiment of the present application, when the fourth outlet segment 34 has no plate, the first conveying speed may be reduced to a very small preset speed, and the operation of the fourth outlet segment 34 may also be directly stopped.

In the exemplary embodiment of the present application, when there is a plate in the fourth plate discharging section 34, whether the first conveying speed is greater than the conveying speeds of the other plate discharging sections or the first conveying speed is less than or equal to the conveying speeds of the other plate discharging sections, the operation of the fourth plate discharging section 34 may be directly stopped, so as to avoid that when the subsequent equipment of the dryer fails, if the fourth plate discharging section 34 continues to convey a plate to the subsequent equipment, the failure of the subsequent equipment is aggravated.

2. When only the conveying speeds of the first, second, and

third outlet segments

31, 32, and 33 (i.e., the conveying speeds of the other outlet segments) are controlled:

when the Nth plate outlet section has no plate, if the first conveying speed is greater than or equal to the conveying speed of the other plate outlet sections, or the first conveying speed is less than the conveying speed of the other plate outlet sections, increasing the conveying speed of the other plate outlet sections;

In the exemplary embodiment of the present application, when the fourth deck 34 has no plate, the operation of the conveyance speed of the other deck (one or more of the conveyance speeds of the first deck 31, the second deck 32, and the third deck 33) can be increased so as to ensure that the sheet conveyance efficiency can be improved as much as possible without causing serious redundancy, regardless of whether the first conveyance speed is higher than the conveyance speed of the other deck or the first conveyance speed is lower than or equal to the conveyance speed of the other deck.

In the exemplary embodiment of the present application, if the first conveying speed is greater than the conveying speeds of the other plate-discharging sections, and still the fourth plate-discharging section 34 is provided with plates, it indicates that a plate stacking phenomenon may have occurred (at this time, it may be that a subsequent device has a fault), at this time, the conveying speeds of the other plate-discharging sections may be further reduced or the other plate-discharging sections may be controlled to stop operating, and at least the conveying speed of the third plate-discharging section 33 may be stopped (especially when there is a plate on the third plate-discharging section 33), so as to avoid further stacking of the plate on the fourth plate-discharging section 34. If there is a plate on the fourth plate-out section 34 and the first conveying speed is less than or equal to the conveying speeds of the other plate-out sections, it may be determined that the conveying speed of the current other plate-out section has caused pressure on the fourth plate-out section 34, and if a fault occurs in the subsequent equipment, the dryer will be forced to stop, so that the other plate-out sections may be controlled to stop operating, so as to reduce the plate-out pressure of the fourth plate-out section 34 and reduce the risk of the dryer stopping.

3. When the conveying speeds of the first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33 and the fourth plate discharging section 34 are all controlled:

In the exemplary embodiment of the present application, if the first conveying speed is greater than or equal to the conveying speed of the other outgoing lane, and the fourth outgoing lane 34 has no plate, and it is possible that the difference between the conveying speed of the other outgoing lane and the conveying speed of the fourth outgoing lane 34 is too large, the first conveying speed may be temporarily reduced or the fourth outgoing lane 34 may be controlled to stop running, and at the same time, the conveying speed of the other outgoing lane may be increased; so that the plate can be output uniformly, and the phenomena of non-uniformity, such as no plate in the plate outlet area 3, frequent accumulation and the like can not be caused. In addition, temporarily reducing the first conveying speed or controlling the fourth outgoing plate section 34 to stop running can cause the subsequent equipment to pass the fault, and the speed of the fourth outgoing plate section 34 for conveying the plates outwards is reduced to the minimum so as to reduce the stress on the subsequent equipment.

In the exemplary embodiment of the present application, if the first conveying speed is lower than the conveying speeds of the other panel discharging sections and the fourth panel discharging section 34 has no panel, a panel breakage (i.e., panel absence) phenomenon may occur in the third panel discharging section 33, and at this time, the fourth panel discharging section 34 may be controlled to stop running to wait for the first panel discharging section 31, the second panel discharging section 32, and the like in front to convey the panel. Meanwhile, the conveying speed of the other plate discharging sections can be increased; so as to improve the plate conveying speed of the first plate discharging section 31 and the second plate discharging section 32, thereby improving the plate discharging efficiency of the plate discharging area 3. At this time, since the fourth plate outlet section 34 has no plate, even if the subsequent equipment fails, the fourth plate outlet section 34 does not cause approval pressure and influence on the subsequent equipment, and thus, the plate outlet section before the fourth plate outlet section 34 can still continue to operate normally at this time.

In the exemplary embodiment of the present application, the fourth board exiting section 34 has boards, and at this time, whether the first conveying speed is greater than the conveying speeds of the other board exiting sections or the first conveying speed is less than or equal to the conveying speeds of the other board exiting sections, the first conveying speed may be reduced, and even the fourth board exiting section 34 may be controlled to stop operating, and the conveying speeds of the other board exiting sections may be reduced to reduce the speed at which the other board exiting sections continue to convey boards to the fourth board exiting section 34, so as to reduce the pressure of the fourth board exiting section 34, avoid causing the boards to be stacked, and avoid that the dryer has to stop operating once the subsequent equipment fails.

Scheme two can be described in detail below.

In an exemplary embodiment of the present application, it may be first detected whether there is a board in the fourth board outlet section 34 or whether there is a board in the other board outlet sections after detecting that there is no board in the fourth board outlet section 34; and adjusting the first conveying speed and/or the conveying speed of the other plate discharging sections according to a second detection result.

In the exemplary embodiment of the present application, if it is detected that all of the first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33, and the fourth plate discharging section 34 have plates, it may be predicted that the plate will be stacked more frequently, and once the subsequent equipment fails, the drier may be stopped more frequently, so that in this case, the plurality of plate discharging sections may be controlled to stop running for a certain period of time, and at least all of the plate discharging sections may be restarted after the plate on the fourth plate discharging section 34 is transported by the subsequent equipment, or only the third plate discharging section 33 may be started.

In the exemplary embodiment of the present application, if it is detected that none of the first board outlet section 31, the second board outlet section 32, the third board outlet section 33, and the fourth board outlet section 34 has any board, at this time, a problem may occur in the board inlet area 1 and/or the closed drying area 2, and therefore, at this time, the fourth board outlet section 34 may be controlled to stop operating to reduce power consumption, and other operating sections may reduce the speed to prepare to convey the board sent out from the closed drying area 2 at any time. The first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33 and the fourth plate discharging section 34 can also be stopped from running and restarted after the plates are sent out from the closed drying area 2, so that on one hand, the power consumption can be reduced, and on the other hand, more plate conveying time can be provided when the follow-up equipment breaks down, so that more time can be provided for the follow-up equipment maintenance.

In the exemplary embodiment of the present application, if the fourth board exiting section 34 has no board, it indicates that the conveying speed of other board exiting sections is slow, the board exiting section (which may be any one of the first board exiting section 31, the second board exiting section 32, and the third board exiting section 33) closest to the fourth board exiting section 34 may be controlled to increase the conveying speed, and all the board exiting sections between the board exiting section and the fourth board exiting section 34 may be controlled to increase the conveying speed; so as to ensure the normal board conveying efficiency. At this time, since there is no plate on the fourth plate discharging section 34, even if the subsequent equipment fails, the fourth plate discharging section 34 will not cause pressure on the subsequent equipment, and the normal operation of the dryer will not be affected.

In the exemplary embodiment of the present application, if there is a plate in the fourth plate discharging section 34, and none of the first plate discharging section 31, the second plate discharging section 32, and the third plate discharging section 33 has a plate, the fourth plate discharging section 34 may be controlled to stop running temporarily to wait for the other plate discharging sections to transport the plate, and at this time, the first plate discharging section 31, the second plate discharging section 32, and the third plate discharging section 33 may also reduce the speed temporarily to wait for the plate sent out by the closed drying area 2.

In the exemplary embodiment of the present application, if the fourth board outlet section 34 has boards and the third board outlet section 33 has boards (or the second board outlet section 32 and the third board outlet section 33 all have boards, or the first board outlet section 31, the second board outlet section 32 and the third board outlet section 33 all have boards), the board outlet sections of the boards may be controlled to stop running, so as to reduce the pressure of the fourth board outlet section 34, avoid the boards from being stacked, and make the dryer have to stop when the subsequent equipment fails.

In the exemplary embodiment of the present application, if the fourth board outlet section 34 has boards, and the third board outlet section 33 has no boards, and the second board outlet section 32 has boards (or the second board outlet section 32 and the third board outlet section 33 both have no boards, and only the first board outlet section 31 has boards), the fourth board outlet section 34 may be controlled to stop running to wait for the board to be conveyed, and the conveying speed of the other board outlet sections (the first board outlet section 31, the second board outlet section 32, and the third board outlet section 33) is increased to quickly convey the board to the fourth board outlet section 34, at this time, because there is no board on the fourth board outlet section 34, even if the subsequent equipment fails, the fourth board outlet section 34 will not cause pressure on the subsequent equipment, and the normal operation of the dryer is not affected.

In an exemplary embodiment of the present application, the second scheme may adjust the first conveying speed and/or the conveying speed of the other outgoing board segment directly according to a preset operation table; wherein, the operation table comprises: a panel/non-panel information group and a speed information group; each plate-contained/plate-free information group corresponds to a group of speed information groups; each information group with or without board comprises an information combination form of a plurality of board-out sections with or without boards; each velocity information set includes a velocity combination of a plurality of outgoing plate segments corresponding to a plate/non-plate information set.

In an exemplary embodiment of the present application, one embodiment of a run list may be as shown in FIG. 3.

In the exemplary embodiment of the present application, A, B, C, D represents the first outlet segment 31, the second outlet segment 32, the third outlet segment 33, and the fourth outlet segment 34, respectively, 1 represents presence of a plate, 0 represents absence of a plate, e represents stop operation, l represents low speed operation, and h represents high speed operation.

The third scheme can be described in detail as follows.

In the exemplary embodiment of the present application, it is possible to detect whether there are plates and their conveying speeds in any one or more of the first plate discharge section 31, the second plate discharge section 32, the third plate discharge section 33, and the fourth plate discharge section 34 at the same time, and adjust the speed of each plate discharge section.

In the exemplary embodiment of the present application, if it is detected that all of the first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33, and the fourth plate discharging section 34 have plates, it may be predicted that the probability that plates will be stacked is relatively high, and once the subsequent equipment fails, the probability that the dryer is stopped is relatively high, so no matter the speed of the first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33, and the fourth plate discharging section 34 is relatively high, in this case, the plurality of plate discharging sections may be controlled to stop running for a certain time, and at least, all of the plate discharging sections may be restarted after the plates on the fourth plate discharging section 34 are carried away by the subsequent equipment, or only the third plate discharging section 33 may be started.

In the exemplary embodiment of the present application, if it is detected that none of the first board outlet section 31, the second board outlet section 32, the third board outlet section 33, and the fourth board outlet section 34 has any board, at this time, a problem may occur in the board inlet area 1 and/or the closed drying area 2, and therefore, no matter the speed of the first board outlet section 31, the second board outlet section 32, the third board outlet section 33, and the fourth board outlet section 34, the fourth board outlet section 34 may be controlled to stop running to reduce power consumption, and the speed of the other running sections may be reduced to prepare to convey the board sent out from the closed drying area 2 at any time. The first plate discharging section 31, the second plate discharging section 32, the third plate discharging section 33 and the fourth plate discharging section 34 can also be stopped from running and restarted after the plates are sent out from the closed drying area 2, so that on one hand, the power consumption can be reduced, and on the other hand, more plate conveying time can be provided when the follow-up equipment breaks down, so that more time can be provided for the follow-up equipment maintenance.

In the exemplary embodiment of the present application, when the fourth outgoing board section 34 has no board, if the first conveying speed is greater than or equal to the conveying speeds of the other outgoing board sections, the first conveying speed may be reduced, the other outgoing board sections may be waited to convey the board (if the first conveying speed is less than the conveying speeds of the other outgoing board sections, the fourth outgoing board section 34 may be controlled to directly stop operating), and the conveying speeds of the other outgoing board sections may be increased, so as to improve the conveying efficiency as soon as possible, at this time, even if the subsequent equipment fails, because no board exists on the fourth outgoing board section 34, the fourth outgoing board section 34 may not cause pressure on the subsequent equipment, and the normal operation of the dryer may not be affected.

In the exemplary embodiment of the present application, if the fourth outgoing board section 34 has a board, and no board is on the other outgoing board section, whether the first conveying speed is greater than or equal to the conveying speed of the other outgoing board section or the first conveying speed is less than the conveying speed of the other outgoing board section, the fourth outgoing board section 34 may be controlled to stop running, and the conveying speed of the other outgoing board section may be maintained or reduced. When no plate is arranged on other plate discharging sections, the fourth plate discharging section 34 can be controlled to stop running, the conveying speed of the other plate discharging sections is reduced, the other plate discharging sections can also be controlled to stop running to wait for the plate sent out by the closed drying area 2, at the moment, the fourth plate discharging section 34 cannot cause any pressure on subsequent equipment, and even if the subsequent equipment breaks down, the subsequent equipment cannot be influenced, so that the drying machine cannot be stopped. Controlling the fourth board exiting section 34 to stop operating and reducing the conveying speed of the other board exiting sections, even controlling the other board exiting sections to stop operating can reduce power consumption.

In the exemplary embodiment of the present application, if the fourth board outlet section 34 has a board, and one or more board outlet sections that are continuously adjacent to the fourth board outlet section 34 on the other board outlet sections have a board (that is, the third board outlet section 33 has a board, or the second board outlet section 32 and the third board outlet section 33 have a board, or the first board outlet section 31, the second board outlet section 32 and the third board outlet section 33 all have a board), when the first conveying speed is greater than or equal to the conveying speed of the other board outlet sections, the fourth plate-out section 34 can be controlled to stop running, the third plate-out section 33 can be controlled to have plates, or the second plate outlet section 32 and the third plate outlet section 33, or the first plate outlet section 31, the second plate outlet section 32 and the third plate outlet section 33 stop running, reducing the conveying speed of the plate discharging sections without plates on the other plate discharging sections or controlling the plate discharging sections without plates on the other plate discharging sections to stop running; in this embodiment, if the first conveying speed is greater than or equal to the conveying speed of the other plate discharging sections, and plates are still provided on the consecutive plate discharging sections of the fourth plate discharging section 34, it indicates that the conveying speed of the other plate discharging sections is too fast, the plate discharging sections with the plates are controlled to stop running, the pressure of the fourth plate discharging section 34 can be reduced, plate stacking is avoided, and the dryer has to be stopped when the subsequent equipment fails.

In an exemplary embodiment of the present application, if the fourth board outlet section 34 has a board, and one or more board outlet sections, which are continuously adjacent to the fourth board outlet section 34, on the other board outlet sections have a board, and the first conveying speed is lower than the conveying speed of the other board outlet sections, the fourth board outlet section 34 is controlled to stop running, and the one or more board outlet sections, which are continuously adjacent to the fourth board outlet section 34, are controlled to stop running or the conveying speed of the one or more board outlet sections, which are continuously adjacent to the fourth board outlet section 34, is reduced, and the conveying speed of the board outlet section without a board on the other board outlet sections is reduced or the board outlet sections without a board on the other board outlet sections are controlled to stop running; in this embodiment, if the first conveying speed is lower than the conveying speeds of the other plate discharging sections, and there are still plates on several continuous plate discharging sections of the fourth plate discharging section 34, the speed of the plate discharging of the fourth plate discharging section 34 may be lower, at this time, to avoid plate stacking, the operation of all the plate discharging sections may be stopped, and the conveying speeds of the other plate discharging sections may also be reduced to reduce the pressure of the fourth plate discharging section 34, so as to avoid plate stacking.

In an exemplary embodiment of the present application, if the fourth outgoing board section 34 has a board, and one or more board-free outgoing board sections are included between the board-having outgoing board section closest to the fourth outgoing board section 34 in the other outgoing board sections and the fourth outgoing board section 34, whether the first conveying speed is greater than or equal to the conveying speed of the other outgoing board sections or the first conveying speed is less than the conveying speed of the other outgoing board sections, the first conveying speed may be decreased or the fourth outgoing board section 34 may be controlled to stop operating, and the conveying speed of the other outgoing board sections may be increased. By reducing the first conveying speed or controlling the fourth plate discharging section 34 to stop running, on one hand, the plate can be waited for to be conveyed, so that the power consumption is reduced, on the other hand, the pressure of the fourth plate discharging section 34 on subsequent equipment can be reduced, and the conveying speed of other plate discharging sections can be increased, so that the conveying efficiency can be improved.
