Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gypsum board production, and more particularly to a conveying system and a control method thereof, and a gypsum board production line. BACKGROUND

[0002] Paper-faced gypsum board is a light-weight building board made of gypsum and face paper as main raw materials, and water, foaming agent, setting accelerator, starch, fiber, etc. as auxiliary materials. It has the characteristics of heat preservation, light weight, sound insulation, fire resistance, good decoration performance, easy construction, space saving, energy saving and environmental protection, etc.

[0003] In the process of gypsum board production, the main body board will be cut into sub-boards by a cutter mechanism at the front of the main body board during the conveying process after hardening. The sub-boards are then conveyed into a drying machine for drying. On the one hand, due to the problem of softening in some local positions of the main body board, if the cutter cuts at the softening position, the sub-boards cannot be completely cut off (i.e., the sub-boards are still connected to the main body board), resulting in waste boards. On the other hand, due to the serious wear of the cutter during the cutting process, if the cutter is not replaced in time, the sub-boards cannot be completely cut off (i.e., the sub-boards are still connected to the main body board), resulting in waste boards.

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0023] This invention provides a transmission system, such as... Figure 1 As shown, it includes: a first conveyor track configured to convey the main body plate 300; a second conveyor track 200 located downstream of the first conveyor track and configured to convey sub-plates 310 cut from the front of the main body plate 300; a cutting mechanism 400 located between the first and second conveyor tracks 200 and configured to sequentially cut the sub-plates 310 from the front of the main body plate 300; a first detection device configured to detect whether the sub-plates 310 have been completely cut off; and an alarm module configured to output alarm information if the sub-plates 310 have not been completely cut off.

[0024] The conveying system detects whether the sub-plate 310 is completely cut down through the first detection device, and outputs alarm information through the alarm module when the sub-plate 310 is not completely cut down, so as to timely inform the operating personnel when the waste plate is generated, and ensure that the operating personnel can timely analyze the reason for generating the waste plate and make corresponding response processing measures, so that the generation amount of the waste plate can be reduced.

[0025] In some examples, as shown in Figure 1 The cutter mechanism 400 includes a cutter and a driving assembly, the cutter is installed on the driving assembly, the moving stroke of the cutter includes a cutter initial position and a cutter terminal position, the cutter initial position and the cutter terminal position are both located between the first conveying track and the second conveying track 200 and are on both sides of the main plate 300, and the driving assembly is arranged to drive the cutter to reciprocate between the cutter initial position and the cutter terminal position, so as to cut the sub-plates 310 in sequence at the front of the main plate 300.

[0026] In some examples, as shown in Figure 1As shown, the first detection device comprises: a cutter detection module 510, which is arranged to detect whether the cutter reaches the cutter termination position, and the cutter detection module 510 is triggered when the cutter is located at the cutter termination position, and the cutter detection module 510 is not triggered when the cutter is not located at the cutter termination position; a first timing module, which is arranged to start timing from a first initial time based on the cutter detection module 510 being triggered; a first gap detection module 520, which is located downstream of the cutter detection module 510, and the first gap detection module 520 is arranged to detect the interval between the sub-plate 310 and the main plate 300, and the first gap detection module 520 is triggered when the interval between the sub-plate 310 and the main plate 300 is detected, and the first gap detection module 520 is not triggered when the interval between the sub-plate 310 and the main plate 300 is not detected, that is, "when the uppermost sub-plate 310 is completely cut off, the sub-plate 310 moves forward in priority to the main plate 300 to form an interval with the main plate 300, and when the interval moves to a position corresponding to the first gap detection module 520, the first gap detection module 520 is triggered", "when the uppermost sub-plate 310 is not completely cut off, the sub-plate 310 moves forward together with the main plate 300 due to the pulling of the main plate 300, and there is no interval between the sub-plate 310 and the main plate 300, so the first gap detection module 520 is not triggered"; and a first control module, which is arranged to control the alarm module to output alarm information in the process that the timing duration of the first timing module reaches a first set timing duration t1, based on the first gap detection module 520 being in a state of not being triggered all the time (i.e., the plate is not completely cut off, and there is no interval between the sub-plate 310 and the main plate 300). t1 is determined according to experiments or calculations.

[0027] Wherein, in the conveying direction of the main plate 300, the distance between the first gap detection module 520 and the cutter detection module 510 is d, the length of the sub-plate 310 in the conveying direction of the main plate 300 is a, the average conveying speed of the sub-plate 310 between the cutter detection module 510 and the first gap detection module 520 is v, a>d, d / v

[0028] The control method of the conveying system comprises: based on the cutter detection module 510 being triggered, controlling the first timing module to start timing from a first initial time, and in the process of the timing duration of the first timing module reaching a first set timing duration t1, based on the first gap detection module 520 being in a state of not being triggered all the time, controlling the alarm module to output alarm information, so as to timely notify the operating personnel when the waste board is generated, and ensure that the operating personnel can timely analyze the reason for generating the waste board and make corresponding response processing measures (stop and replace the cutter when the cutter is seriously worn), so that the generation amount of waste boards can be reduced.

[0029] In some embodiments, as shown in Figure 1 The cutter detection module 510 is arranged as a proximity switch, the proximity switch is arranged at the cutter termination position, the proximity switch is not easy to be damaged, and the procurement cost is low.

[0030] In some embodiments, as shown in Figure 1 The first gap detection module 520 is arranged as a photoelectric switch, the photoelectric switch is not easy to be damaged, and the procurement cost is low.

[0031] In some examples, as shown in Figure 1 The conveying system further comprises: a third conveying track 600 movably arranged, the third conveying track 600 is located downstream of the second conveying track 200; a fourth conveying track and a waste board discharging track, both of which are located downstream of the third conveying track 600, an upstream end of the third conveying track 600 is connected to the second conveying track 200, and a downstream end of the third conveying track 600 is connected to any one of the fourth conveying track and the waste board discharging track; and a second detection device, which is arranged to detect whether a sub-board b about to be conveyed to the shunt track is connected to a sub-board 310 upstream of the sub-board b, the third conveying track 600 is arranged to be connected to the waste board discharging track based on the sub-board b about to be conveyed to the shunt track being connected to the sub-board 310 upstream of the sub-board b, the waste board (the sub-board b about to be conveyed to the shunt track and the sub-board 310 upstream of the sub-board b) is conveyed by the waste board discharging track to be discharged, and the third conveying track 600 is further arranged to be connected to the fourth conveying track based on the sub-board b about to be conveyed to the shunt track not being connected to the sub-board 310 upstream of the sub-board b, and the sub-board b is conveyed by the fourth conveying track to the drying machine. It can be that a pneumatic cylinder is arranged at the downstream end of the third conveying track 600, the waste board discharging track is located above the fourth conveying track, the pneumatic cylinder lifts the downstream end of the third conveying track 600, the downstream end of the third conveying track 600 is connected to the waste board discharging track, the pneumatic cylinder lowers the downstream end of the third conveying track 600, and the downstream end of the third conveying track 600 is connected to the fourth conveying track. A sub-board c downstream of the sub-board b about to be conveyed to the shunt track has been shunted to the shunt track.

[0032] In some examples, such as Figure 1 As shown, the second detection device includes: a second gap detection module 900, which is disposed between the second conveying track 200 and the third conveying track 600. The second gap detection module 900 is configured to detect the gap between adjacent sub-plates 310, and is triggered when it detects the gap between adjacent sub-plates 310 (i.e., the gap between adjacent sub-plates 310 moves to a position corresponding to the second gap detection module 900), and is not triggered when it does not detect the gap between adjacent sub-plates 310 (i.e., the second gap detection module 900 is blocked by the sub-plates 310); and a second timing module, which is configured to detect the gap based on the second gap detection module 900. The timing module 900 is triggered and starts timing from the second initial time; the second control module is set to control the third conveying track 600 to dock with the waste discharge track when the timing duration of the second timing module reaches the second set timing duration t2, based on the fact that the second gap detection module 900 is always in the triggered state (i.e., the sub-board b to be conveyed to the diversion track is connected to the sub-board 310 upstream of the sub-board b), and based on the fact that the second gap detection module 900 changes from the triggered state to the untriggered state (i.e., the sub-board b to be conveyed to the diversion track is not connected to the sub-board 310 upstream of the sub-board b), then the third conveying track 600 is controlled to dock with the fourth conveying track.

[0033] Taking three consecutive sub-plates 310 from upstream to downstream as an example, under normal circumstances, the interval between the first sub-plate 310 and the second sub-plate 310 is the same as the interval between the second sub-plate 310 and the third sub-plate 310. The time t takes for this interval to pass through the second gap detection module 900 is t. m The time t is when a sub-plate 310 passes through the second gap detection module 900. k If the second sub-plate 310 and the third sub-plate 310 are connected but not completely cut off, the distance between the first sub-plate 310 and the second sub-plate 310 increases. The time it takes for this gap to pass through the second gap detection module 900 is t. n , t m <t n <t k , t m <t2<t nTherefore, by reasonably setting t2 (determined by experiment or calculation), in the process that the timing duration of the second timing module reaches the second set timing duration t2, if the second gap detection module 900 is always in the triggered state, the sub-plate b about to be conveyed to the shunt track is connected with the sub-plate 310 upstream of the sub-plate b, the third conveying track 600 is controlled to be connected with the waste track, and the waste plate (i.e., the sub-plate b about to be conveyed to the shunt track and the sub-plate 310 upstream of the sub-plate b) is conveyed to the waste track through the third conveying track 600 for waste disposal, if the second gap detection module 900 changes from the triggered state to the untriggered state, the sub-plate b about to be conveyed to the shunt track is not connected with the sub-plate 310 upstream of the sub-plate b, the third conveying track 600 is controlled to be connected with the fourth conveying track, and the sub-plate b about to be conveyed to the shunt track is conveyed from the third conveying track 600 to the fourth conveying track and then to the drying machine.

[0034] The control method of the conveying system comprises the following steps: based on the second gap detection module 900 being triggered, the second timing module is controlled to start timing from the second initial time, and in the process that the timing duration of the second timing module reaches the second set timing duration t2, based on the second gap detection module 900 being always in the triggered state, the sub-plate b about to be conveyed to the shunt track is connected with the sub-plate 310 upstream of the sub-plate b, the third conveying track 600 is controlled to be connected with the waste track, and the waste plate (i.e., the sub-plate b about to be conveyed to the shunt track and the sub-plate 310 upstream of the sub-plate b) is conveyed to the waste track through the third conveying track 600 for waste disposal, based on the second gap detection module 900 changing from the triggered state to the untriggered state, the sub-plate b about to be conveyed to the shunt track is not connected with the sub-plate 310 upstream of the sub-plate b, the third conveying track 600 is controlled to be connected with the fourth conveying track, and the sub-plate b about to be conveyed to the shunt track is conveyed from the third conveying track 600 to the fourth conveying track and then to the drying machine.

[0035] In some embodiments, as shown in FIG. 9, the second gap detection module 900 is arranged as a photoelectric switch, which is not easy to be damaged and has low procurement cost. Figure 1

[0038] ​In summary, the conveying system provided by the embodiment of the present application detects whether the sub-plate material is completely cut down through the first detection device, and outputs alarm information through the alarm module when the sub-plate material is not completely cut down, so as to timely inform the operator when the waste plate is generated, and ensure that the operator can timely analyze the reason for generating the waste plate and make corresponding response processing measures, so that the generation amount of the waste plate can be reduced.
