[0060] Embodiments

[0061] During the production process of ceramic tiles, the glaze on the tile blank needs to be sintered by a glaze firing kiln. When the glaze firing kiln is working, it usually supplies materials by three conveyors. The models of the tile blanks on the three conveyors can be the same or different. When the models of the tile blanks supplied by the three conveyors are different, three conveyors also need to be arranged at the outlet of the glaze firing kiln to convey the different models of the ceramic tiles after the glaze firing.

[0062] However, the three discharge conveyor roller frames may fail, causing the conveyors to temporarily fail to convey the ceramic tiles. Therefore, a standby conveyor is also arranged to replace the failed conveyor to convey the ceramic tiles.

[0063] In the traditional solution, one glaze firing kiln needs one additional standby conveyor. The number of glaze firing kilns is the same as the number of standby conveyors. For example, when two glaze firing kilns are arranged, two standby conveyors are needed, and the two conveyors will occupy a large area.

[0064] Therefore, the present application provides a standby production line for a glaze firing kiln, which combines Figure 1 and Figure 2 The standby production line 1 for the glaze firing kiln includes a first standby unit 10 and a second standby unit 20. The first standby unit 10 is arranged downstream of a glaze firing kiln A, and the second standby unit 20 is arranged downstream of another glaze firing kiln A. When the corresponding three discharge conveyor roller frames of the glaze firing kiln A fail, the first standby unit 10 or the second standby unit 20 is enabled. The first standby unit 10 includes a first conveying structure 11, a first reversing roller frame 12, and a second conveying structure 13 connected in sequence. A fifth conveying structure 30 is arranged downstream of the second conveying structure 13. The second standby unit 20 includes a third conveying structure 21, a second reversing roller frame 22, and a fourth conveying structure 23. The fourth conveying structure 23 is arranged directly above the fifth conveying structure 30 and is rotationally connected to the second reversing roller frame 22. An end of the fourth conveying structure 23 away from the second reversing roller frame 22 can move up and down. When the first standby unit 10 is not working, the end of the fourth conveying structure 23 moves close to the fifth conveying structure 30. The first standby unit 10 and the second standby unit 20 can share the fifth conveying structure 30. The standby production line 1 can convey the ceramic tiles at the first standby unit 10 or the second standby unit 20 through the fifth conveying structure 30. That is, the two glaze firing kilns A can convey the ceramic tiles through the fifth conveying structure 30, thereby reducing the area occupied by the equipment.

[0065] More specifically, in combination with Figure 7 and Figure 9 , as shown in the fourth conveying structure 23, the fourth conveying structure 23 can move from a horizontal position as shown in Figure 9 to a vertical position as shown in Figure 7The tilting position enables the tiles on the second backup unit 20 to move from the fourth transfer structure 23 to the fifth transfer structure 30, so that the backup production line 1 only needs one total outfeed transfer structure.

[0066] Further in combination with Figures 3-5 In an embodiment of the present application, a first sensor 14 is arranged downstream of the first transfer structure 11, and a second sensor 15 is arranged upstream of the second transfer structure 13. A third sensor 24 is arranged downstream of the third transfer structure 21, and a fourth sensor 25 is arranged upstream of the fourth transfer structure 23. A controller 40 is arranged beside the second backup unit 20. The controller 40 is electrically connected to the first sensor 14, the second sensor 15, the third sensor 24 and the fourth sensor 25 respectively.

[0067] Specifically, the first sensor 14 is used to control the start and stop of the first transfer structure 11. The second sensor 15 is used to control the rotation of the second transfer structure 13. The third sensor 24 is used to control the start and stop of the third transfer structure 21. The fourth sensor 25 is used to control the rotation of the fourth transfer structure 23.

[0068] In an embodiment of the present application, for example, when the first backup unit 10 is working and the second backup unit 20 is not working, i.e. when tiles are transferred from the first transfer structure 11 to the first sensor 14, the first sensor 14 receives a signal and feeds back to the controller 40. If at this time neither the third sensor 24 nor the fourth sensor 25 feeds back a signal to the controller 40, the controller 40 controls the first transfer structure 11 to continue transferring tiles. When the tiles move from the first transfer structure 11 and the first reversing roller frame 12 to the second transfer structure 13, the second sensor 15 receives a signal and feeds back the signal to the controller 40. The controller 40 controls the fourth transfer structure 23 to rotate and move to a position as shown in Figure 9 The tiles move smoothly through the second transfer structure 13 to the fifth transfer structure 30. Then the tiles move from the fifth transfer structure 30 to the subsequent transfer structure until being carried by the brick laying machine C.

[0069] Specifically, in the initial state, since the second sensor 15 does not receive a signal of tiles for more than 20s, the fourth transfer structure 23 is in the state as shown in Figure 7 to reduce the burden of the driving structure for driving the fourth transfer structure 23.

[0070] When the first backup unit 10 is working, the second backup unit 20 has been working, i.e. there is tile conveying to the first sensor 14 at the first conveying structure 11, the first sensor 14 receives the signal and feeds back to the controller 40. If at this time the third sensor 24 or the fourth sensor 25 feeds back the signal to the controller 40, the controller 40 controls the first conveying structure 11 to stop conveying the tile, and the tile is temporarily accumulated upstream of the first conveying structure 11.

[0071] In an embodiment of the present application, if the third sensor 24 and the fourth sensor 25 both feed back the signal to the controller 40, the controller 40 controls the first conveying structure 11 to stop conveying the tile, and the tile is temporarily accumulated upstream of the first conveying structure 11.

[0072] In an embodiment of the present application, if only the fourth sensor 25 feeds back the signal to the controller 40, the controller 40 controls the first conveying structure 11 to stop conveying the tile, and the tile is temporarily accumulated upstream of the first conveying structure 11. When only the fourth sensor 25 feeds back the signal, it indicates that the tile on the second backup unit 20 is about to be conveyed. After 20s when no signal is fed back to the controller 40 at the fourth sensor 25, the fourth conveying structure 23 is turned upward to the state as shown in Figure 9 , and the first conveying structure 11 starts to work.

[0073] In an embodiment of the present application, when there is no tile conveying on the first backup unit 10 and the second backup unit 20 (the second sensor 15 and the fourth sensor 25 do not sense the tile for more than 20s), the fourth conveying unit is turned clockwise to the state as shown in Figure 7 , i.e. the initial state mentioned above.

[0074] When the second backup unit 20 is working and the first backup unit 10 is not working, i.e. there is tile conveying to the third sensor 24 at the third conveying structure 21, the third sensor 24 receives the signal and feeds back to the controller 40. If at this time the first sensor 14 and the second sensor 15 do not feed back the signal to the controller 40, the controller 40 controls the first conveying structure 11 to continue conveying the tile. Since the fourth conveying structure 23 is in the state as shown in Figure 7 when the second sensor 15 does not receive the signal for 20s, the tile continues to be conveyed normally. The tile moves to the fifth conveying structure 30 through the fourth conveying structure 23 successfully. Then the tile moves from the fifth conveying structure 30 to the subsequent conveying structure until it is carried by the tile placing machine C.

[0075] When the second backup unit 20 is working, the first backup unit 10 has been working, i.e. the tiles are conveyed to the third sensor 24 at the third conveying structure 21, the third sensor 24 receives the signal and feeds back to the controller 40. If the first sensor 14 or the second sensor 15 feeds back the signal to the controller 40 at this time, the controller 40 controls the third conveying structure 21 to stop conveying the tiles, and the tiles are temporarily accumulated upstream of the third conveying structure 21.

[0076] In an embodiment of the present application, if the first sensor 14 and the second sensor 15 both feed back the signal to the controller 40, the controller 40 controls the first conveying structure 11 to stop conveying the tiles, and the tiles are temporarily accumulated upstream of the first conveying structure 11.

[0077] In an embodiment of the present application, if only the second sensor 15 feeds back the signal to the controller 40, the controller 40 controls the third conveying structure 21 to stop conveying the tiles, and the tiles are temporarily accumulated upstream of the third conveying structure 21. When only the second sensor 15 feeds back the signal, it indicates that the tiles on the first backup unit 10 are about to be conveyed. When the second sensor 15 does not feed back the signal to the controller 40 for 20 s, the fourth conveying structure 23 is turned down to the state as shown in Figure 7 , and the third conveying structure 21 starts to work.

[0078] In an embodiment of the present application, the fifth sensor 50, the sixth sensor 60 and the seventh sensor 70 are further included.

[0079] In combination with Figure 4 , Figure 5 and Figure 10 , the fifth sensor 50 is installed beside the second sensor 15, the sixth sensor 60 is installed beside the fourth sensor 25. A conveying structure with a certain length is further arranged between the fifth conveying structure 30 and the tile laying machine C, and the seventh sensor 70 is arranged between the fifth conveying structure 30 and the tile laying machine C. The fifth sensor 50, the sixth sensor 60 and the seventh sensor 70 are all electrically connected with the controller 40. The fifth sensor 50 cooperates with the seventh sensor 70 to stop the first conveying structure 11, and the sixth sensor 60 cooperates with the seventh sensor 70 to stop the third conveying structure 21.

[0080] When the tiles are accumulated between the third conveying structure 21 and the tile laying machine C, the seventh sensor 70 between the fifth conveying structure 30 and the tile laying machine C feeds back the signal to the controller 40 one by one. When the tiles are accumulated from the tile laying machine C to the fifth sensor 50, the fifth sensor 50 feeds back the signal to the controller 40, indicating that a large number of tiles have been accumulated at this time, and the controller 40 controls the first conveying structure 11 to stop conveying, so as to avoid further accumulation of the tiles between the first backup unit 10 and the tile laying machine C.

[0081] When the tiles on the conveying structure between the fourth conveying structure 23 and the tile down machine C are stacked, the seventh sensor 70 located between the fifth conveying structure 30 and the tile down machine C feeds back signals to the controller 40 one by one, and when the tiles are stacked from the tile down machine C to the sixth sensor 60, the sixth sensor 60 feeds back signals to the controller 40, indicating that a large number of tiles have been stacked at this time, and the controller 40 controls the third conveying structure 21 to stop conveying to avoid further stacking of tiles between the second standby unit 20 and the tile down machine C.

[0082] In an embodiment of the present application, the first sensor 14, the second sensor 15, the third sensor 24, the fourth sensor 25, the fifth sensor 50, the sixth sensor 60 and the seventh sensor 70 can be one of an electric eye, a laser sensor or an infrared sensor, which is not limited in the embodiment.

[0083] In an embodiment of the present application, the seventh sensor 70 is generally provided with three to four, and the number of seventh sensors 70 are equidistantly spaced between the fifth conveying structure 30 and the tile down machine C.

[0084] Further, referring to Figures 6-9 , the fourth conveying structure 23 comprises a first mounting frame 231, a connecting frame 232 and a rotating rod 233, the first mounting frame 231 is rotatably connected with a first rotating shaft 2311, two first pulleys 2312 are fixedly connected on the first rotating shaft 2311 at intervals, the rotating rod 233 is arranged on one side of the first mounting frame 231, two second pulleys 2331 are fixedly connected on the rotating rod 233 at intervals, and the first pulley 2312 and the second pulley 2331 are connected by a belt. That is, the motor installed on the first mounting frame 231 drives the first rotating shaft 2311 to rotate, and then drives the first pulley 2312 to rotate and further drives the rotating rod 233 to rotate.

[0085] One end of the connecting frame 232 is rotatably connected with the first rotating shaft 2311, the other end of the connecting frame 232 is rotatably connected with the rotating rod 233, and the fourth sensor 25 is installed on the connecting frame 232. The connecting frame 232 and the rotating rod 233 form an integral whole, and when the connecting frame 232 rotates, the rotating rod 233 and the second pulley 2331 follow the rotation. A linear actuator 234 is arranged on the side close to the rotating rod 233, and the linear actuator 234 is used to drive the connecting frame 232 to rotate around the first rotating shaft 2311 as the axis.

[0086] Specifically, in an embodiment of the present application, the fourth conveying structure 23 further comprises a connecting rod 235 and a connecting block 236. Referring to Figure 8 and Figure 9The connecting rod 235 is fixedly connected to the connecting frame 232, and the connecting rod 235 is perpendicular to the conveying direction of the fourth conveying structure 23. One end of the connecting block 236 is rotationally connected to one end of the connecting rod 235, and the other end of the connecting block 236 is rotationally connected to the output end of the linear driver 234. When the linear driver 234 drives the connecting rod 235 to move upward, the connecting rod 235 will drive the connecting frame 232 to rotate counterclockwise, thereby enabling the fourth conveying structure 23 to rotate.

[0087] In order to stabilize the connecting frame 232 during rotation, two linear drivers 234 are provided, and two connecting blocks 236 are provided. The two linear drivers 234 and the two connecting blocks 236 are respectively arranged at the two ends of the connecting rod 235, and the two ends of the connecting block 236 are respectively connected to the connecting rod 235 and the output end of the linear driver 234.

[0088] In an embodiment of the present application, the linear driver 234 can be one of common linear driving structures such as a pneumatic cylinder 8132, an electric cylinder, a screw structure, and a linear motor, which is not limited in the present embodiment. When a different linear driver 234 is selected, the connection part of the linear driver 234 and the connecting block 236 needs to be changed accordingly.

[0089] In an embodiment of the present application, the fifth conveying structure 30 comprises a second mounting frame 31, and the two ends of the second mounting frame 31 are rotationally connected with two second rotating shafts 32, respectively. Two third pulleys 33 are fixedly connected to the second rotating shaft 32 at intervals.

[0090] Further, in an embodiment of the present application, the distance between the two third pulleys 33 on the second rotating shaft 32 is greater than the distance between the two second pulleys 2331. On the basis of the distance between the two third pulleys 33 being greater than the distance between the two second pulleys 2332, in combination with the fact that the first rotating shaft 21 is arranged to be parallel to the second rotating shaft 22, the second pulley 2332 of the fourth conveying structure 23 can be well dropped into the gap between the two third pulleys 33, thereby making the conveying process of the ceramic tiles more stable. Figure 2 At this time, the second pulley 2332 of one end of the fourth conveying structure 23 can be well dropped into the gap between the two third pulleys 33, thereby making the conveying process of the ceramic tiles more stable.

[0091] Specifically, in an embodiment of the present application, referring to Figure 4 The first reversing roller frame 12 comprises an arc-shaped first roller frame 121 and a cylindrical roller 122. The first roller frame 121 comprises a first outer diameter portion 1211 and a first inner diameter portion 1212. The cylindrical roller 122 is installed at intervals between the first outer diameter portion 1211 and the first inner diameter portion 1212 at equal angles. The cylindrical roller 122 is a platform structure, and one end with a larger area is rotationally connected to the first outer diameter portion 1211, thereby avoiding the ceramic tiles from deviating from the second conveying structure 13 under the action of centrifugal force during conveying.
