[0028] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0029] As shown in Figure 1 , an embodiment of the present application provides a gypsum board production equipment and a plate conveying device 100, which can be used for transporting dried plates, and the plates can be gypsum boards. The gypsum board production equipment comprises a drying machine 1 and the plate conveying device 100 arranged at a plate output port of the drying machine 1, and the drying machine 1 is used for drying the plates.

[0030] As shown in Figure 2 , Figure 3As shown, the plate conveying device 100 of the embodiment of the utility model along the conveying direction of the plate comprises a plurality of storage sections 2a, 2b, 2c connected in sequence. Along the height direction of the plate conveying device 100, each storage section comprises a plurality of storage section units 30, each storage section unit 20 comprises a conveying roller 201, a motor 202 driving the conveying roller 201 to move, and one or more plate position detection devices 203 arranged at the plate outlet position.

[0031] The plate conveying device 100 of the embodiment of the utility model further comprises an alarm module 3 arranged to perform full plate alarm when the storage section units 20 of the same layer of the plurality of storage sections 2a, 2b, 2c are all detected by the plate position detection device 203 to have plates, and to perform alarm when the storage section units 20 exceeding the predetermined layer are detected by the plate position detection device 203 to have plates or the sensing time of the plates at the last storage section 2c exceeds the predetermined time.

[0032] For example, the plate position detection device 203 can adopt a separate photoelectricity, and the alarm module 3 can adopt a language module. When the separate photoelectricity 203 of the first storage section 2a, the second storage section 2a, and the third storage section 2c all detect plates, the motor 202 of the first storage section 2a stops and transmits a PLC signal, and informs the post which layer is full of plates through the voice module 3. Under normal circumstances, the number of layers of plates at the third storage section 2c does not exceed 4, and the waiting time of each layer of plates at the third storage section 2c does not exceed 30 seconds. If there are more than 6 layers of plates or the sensing time of the plates at the last storage section exceeds 40 seconds, the PLC signal is transmitted, and the voice module informs the post which layer of the outlet has an abnormal plate. Thus, the voice can not only inform the post to handle the problem in time, but also can pre-store three groups of plates at each layer if the equipment behind the drying machine 1 has a problem, so that the gypsum boards do not crowd together to the front, causing the boards to be stacked.

[0033] The plate conveying device 100 of the embodiment of the utility model can store the gypsum boards in the drying machine 1 when a fault occurs by arranging a plurality of storage sections 2a, 2b, 2c. Meanwhile, the plate position detection device 303 is arranged at the plate outlet position of each storage section unit 20, so that the plates can be accurately stored in each storage section unit, and the plate storage rate is improved. Meanwhile, the alarm module 2 can prevent the plates from crowding together to the front, causing the boards to be stacked.

[0034] The plate position detection device 203 of each layer of the storage section unit 20 of the embodiment of the utility model is arranged upstream of the motor 202 of the layer, so that the plates can be conveyed in time according to the sensed plate signal.

[0035] The plate conveying device 100 is provided with multiple pre-storage systems 2a, 2b and 2c, so that when the downstream system fails, the dryer 1 can run for a period of time and store the output plate for a period of time, thereby preventing the plate in the dryer 1 from being dried unqualifiedly, preventing the plates from colliding and overlapping with each other, and causing the plates to be discarded.

[0036] When the plate position detection device 203 located at the upstream detects a plate signal, and the plate position detection device 203 located at the downstream detects no plate, the motor 202 of the storage section unit 30 at the layer is controlled by the PLC to run at a first predetermined speed; when the storage section unit 20 at the layer detects no plate, the motor 202 at the layer is controlled by the PLC to run at a second predetermined speed; the second predetermined speed is less than the first predetermined speed.

[0037] As shown in Figure 4-5 The end plate detection device 5 comprises a fixed base 51 arranged on the conveying roller 201 at the layer and stopping on the transportation path of the plate, a rotating shaft 52 rotatably arranged on the fixed base 51, one or more baffles 53 arranged on the rotating shaft 52, and a sensing assembly 54. The sensing assembly 54 comprises a first proximity sensor switch 541 and a second proximity sensor switch 542 arranged on the rotating shaft 52 and capable of cooperating with the first proximity sensor switch 541 to trigger a sensing signal. The one or more baffles 53 can be flipped and drive the rotating shaft 52 to rotate under the pushing of the gypsum, so as to drive the second proximity sensor switch 542 to rotate and cooperate with the first proximity sensor switch 541 to trigger a sensing signal.

[0038] The plate position detection device 203 of the embodiment of the utility model can trigger the signal of the sensing assembly by arranging the baffles cooperating with the moving plate to drive the rotating shaft to rotate, can be synchronized with the position reached by the plate, and accurately detect the position of the plate.

[0039] As shown in Figure 5 , Figure 6 The end plate detection device 5 further comprises a mounting disc 55 fixed to the rotating shaft 52, and the first proximity sensor switch 541 is arranged at a position of the mounting disc 55. The first proximity sensor switch 541 is arc-shaped and can be adjusted in the circumferential direction of the mounting disc 55. The disc surface of the mounting disc 55 is provided with multiple mounting holes T arranged at intervals in the circumferential direction, and the second proximity sensor switch 542 is detachably mounted with the mounting hole T by using a connecting piece.

[0040] As shown in Figure 7As shown, the end plate detection device 5 further comprises a reset mechanism 56 for resetting the driving shaft 52, the reset mechanism 56 comprising a gear 561 arranged on the driving shaft 52, a chain 562 engaged with the gear 561, and a counterweight 563 connected with the chain 562.

[0041] The second proximity sensing switch 542 is designed in a semicircular shape and can be adjusted at any angle on the mounting disc 52, and in the embodiment, a plurality of mounting holes T are arranged on the circumference of the mounting disc 52, and the second proximity sensing switch 542 is detachably mounted on the mounting hole T of the mounting disc 52 through a connecting member such as a bolt.

[0042] When the gypsum board arrives, the gypsum board contacts the baffle 53, which is tilted to drive the whole second proximity sensing switch 3033 to rotate and drive the second proximity sensing switch 542 to approach the first proximity sensing switch 541 to send a signal to the DCS system. Thus, when the baffle 53 is worn out by the gypsum board, the position of the second proximity sensing switch 542 enables the second proximity sensing switch 542 to accurately sense the signal.
