Description

Technical Field

[0001] The utility model relates to the technical field of plate conveying equipment, and more specifically, to a plate feeding conveying device and a plate production line. Background Art

[0002] In the prior art, during the plate conveying process of a gypsum board production line, the plates that are accelerating or moving at a constant speed are adjusted to a stationary state by a plate feeding conveying roller table so that the plates can enter the turning conveying roller table. At the front end of the plate feeding conveying roller table, there are a disengaging position and a photoelectric detection sensor, and the photoelectric detection sensor can detect whether the tail end of the plate has left the disengaging position and entered the plate feeding conveying roller table. After the tail end of the plate has left the disengaging position and after a set time, the plate feeding conveying roller table is adjusted from conveying at a constant speed to decelerating conveying, and moreover, the plate feeding conveying roller table stops running within another set time so that the plate comes to a standstill.

[0003] In the prior art, the plates are adjusted to a stationary state on the plate feeding conveying roller table by time control. Due to external factors such as the change in the belt tension of the plate feeding conveying roller table and the change in the paper friction coefficient between the facing paper on the plate surface and the belt, the specific stop position of the plate is uncertain, resulting in an inaccurate turning conveying route for the plate. Therefore, this traditional conveying method cannot meet the requirement for precise control of the plate conveying route. Summary of the Utility Model

[0004] An embodiment of the present application provides a plate feeding conveying device and a plate production line. The plate feeding conveying device includes a first conveying component and a first position detection component. The first position detection component can detect whether the plate reaches a set stop position. When the plate reaches the stop position, the first position detection component sends a signal to stop the first conveying component from conveying, ensuring that the plate can accurately stop at the set stop position. The plate feeding conveying device can achieve precise control of the stop position of the plate during feeding.

[0005] The technical solution of the embodiment of the present application is as follows:

[0006] A plate feeding conveying device, comprising:

The plate feeding end is one end of the first conveying component, and the stop position is located on the downstream side of the plate conveying direction of the plate feeding end; the first conveying component is configured to: be able to decelerate and convey the plates entering the first conveying component from the plate feeding end, and make the plates come to a standstill at the stop position; and

[0008] A first position detection component, configured to: be able to detect whether the plate reaches the stop position, and send a signal to stop the first conveying component from conveying when the plate reaches the stop position so that the plate comes to a standstill.

[0011] The technical effects of the sheet feeding and conveying device according to the embodiment of the present application are as follows:

[0012] The sheet feeding and conveying device according to the embodiment of the present application is configured to include a first position detection assembly. The first conveying assembly includes a set stop position for the sheet. The first position detection assembly can detect whether the sheet reaches the stop position. When the sheet reaches the stop position, the first position detection assembly sends a signal to control the first conveying assembly to immediately stop conveying, so that the sheet accurately docks at the stop position. In this way, with the assistance of the position detection of the first position detection assembly, the sheet can accurately stop at the set stop position. The docking position of the sheet is not affected by external factors such as belt tension changes and the change of the paper friction coefficient between the sheet facing paper and the belt.

[0019] To make the objectives, technical solutions, and advantages of the present application more clear and understandable, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.

[0020] Att Figures 1 to 4 The arrow direction in the figure indicates the conveying direction of the sheet 3.

[0021] Att Figure 1 Schematic structural diagram of a sheet feeding and conveying device 100' in the prior art. As Figure 1 shown, the solution of the sheet feeding and conveying device 100' in the prior art is as follows: The sheet 3 is conveyed to the first conveying component 1 through the second conveying component 5. There is a disengaging position 6 between the second conveying component 5 and the first conveying component 1. The second position detection component 7 can detect whether the tail end of the sheet 3 leaves the disengaging position 6, and send this information to the control component and the driving component 4. The control component can control the driving component 4 to adjust the conveying control of the first conveying component 1. Specifically, after the second position detection component 7 detects that the tail of the sheet 3 leaves the disengaging position 6, after a set time (for example, 0.5 seconds), the first conveying component 1 adjusts from uniformly conveying the sheet 3 to decelerating the conveying of the sheet 3, and then after another set time (for example, 1.5 seconds), the first conveying component 1 stops running so that the sheet 3 is stationary. The prior art realizes the decelerated docking of the sheet 3 through time control. Due to external factors such as the change in the belt tension of the first conveying component 1 and the change in the paper friction coefficient between the surface protective paper of the sheet 3 and the belt, the docking position of the sheet 3 on the first conveying component 1 is uncertain. Therefore, for the sheet feeding and conveying device 100' in the prior art, by setting time to control the first conveying component 1 to perform a delayed deceleration stop plate movement, the precise control of the stop position of the sheet 3 during feeding cannot be satisfied. Further, if the sheet 3 turns from the stop position of the first conveying component 1 to other conveying roller paths for continuous conveying, the conveying route of the sheet 3 on other conveying roller paths cannot be accurately controlled either.

[0022] In view of the above problems, an embodiment of the present application provides a sheet feeding and conveying device 100, as Figures 2 to 4As shown in the figure, the feeding and conveying device 100 of the embodiment of the present application includes a first conveying component 1 and a first position detection component 2. The first conveying component 1 includes a feeding end 11 and a stop position 12. The feeding end 11 is one end of the first conveying component 1, and the stop position 12 is located on the downstream side of the conveying direction of the sheet 3 at the feeding end 11. The first conveying component 1 is configured to: be able to convey the sheet 3 entering the first conveying component 1 from the feeding end 11 at a reduced speed and make the sheet 3 stop at the stop position 12. The first position detection component 2 is configured to: be able to detect whether the sheet 3 reaches the stop position 12, and send a signal to stop the first conveying component 1 from conveying when the sheet 3 reaches the stop position 12 so that the sheet 3 stops.

[0023] Specifically, the feeding and conveying device 100 of the embodiment of the present application is configured to include a first position detection component 2, and the first conveying component 1 includes a stop position 12 set for the sheet 3. The first position detection component 2 can detect whether the sheet 3 reaches the stop position 12. When the sheet 3 reaches the stop position 12, the first position detection component 2 sends a signal to the control component, and the control component controls the first conveying component 1 to stop conveying immediately so that the sheet 3 accurately docks at the stop position 12. In this way, with the assistance of the position detection of the first position detection component 2, the sheet 3 can accurately stop at the set stop position 12. The docking position of the sheet 3 is not affected by external factors such as belt tension change and the change of the paper friction coefficient between the facing paper of the sheet 3 and the belt. The feeding and conveying device 100 of the embodiment of the present application can realize the deceleration of the sheet 3 on the first conveying component 1 and accurate docking of the position. The feeding and conveying device 100 of the present application can realize the precise control of the deceleration stop position of the sheet 3.

[0024] In an exemplary embodiment, as Figures 2 to 4 shown, the feeding and conveying device 100 of the embodiment of the present application further includes a driving component 4. The driving component 4 includes a first driving component, and the first driving component is connected to the first conveying component 1. The first driving component is configured to: be able to provide driving force for the first conveying component 1 to convey the sheet 3 at a reduced speed, and stop running when the first position detection component 2 detects that the sheet 3 reaches the stop position 12.

[0025] Specifically, the driving component 4 is used to provide driving force for conveying the sheet 3 to at least part of the structure of the feeding and conveying device 100. Among them, the first conveying component 1 provides driving force for the first conveying component 1 to convey the sheet 3 at a reduced speed.

[0026] In an exemplary embodiment, as Figures 2 to 4 shown, the feeding and conveying device 100 of the embodiment of the present application further includes a second conveying component 5. The second conveying component 5 is located on the upstream side of the conveying direction of the sheet 3 of the first conveying component 1 and is used to convey the sheet 3 to the feeding end 11.

[0027] Specifically, the second conveying component 5 can be configured to accelerate the conveying of the plate 3 to the plate inlet end 11 of the first conveying component 1, so as to improve the conveying efficiency of the plate 3 of the plate inlet conveying device 100.

[0028] In an exemplary embodiment, as Figures 2 to 4 shown, a disengaging position 6 is provided between the first conveying component 1 and the second conveying component 5, and the plate inlet conveying device 100 further includes a second position detection component 7. The second position detection component 7 is configured to: be able to detect whether the tail of the plate 3 conveyed on the second conveying component 5 leaves the disengaging position 6.

[0029] The first conveying component 1 is configured to: after the second position detection component 7 detects that the tail of the plate 3 leaves the disengaging position 6 and after a set delay time, the first conveying component 1 performs decelerated conveying of the plate 3.

[0030] Specifically, after the second position detection component 7 detects that the tail of the plate 3 leaves the disengaging position 6, the second position detection component 7 sends a signal to the control component, and the control component delays to control the first conveying component 1 to perform decelerated conveying of the plate 3.

[0031] It can be understood that when the production and conveying progress of the plate 3 is satisfied, if the set delay time is longer, the decelerated stop plate action of the plate 3 entering the first conveying component 1 can be smoother, thereby reducing the damage to the plate 3 caused by the decelerated docking action. For example, the delay time of the prior art is 0.5 seconds, and the delay time of the plate inlet conveying device 100 in an embodiment of the present application can be adjusted to 1 second.

[0032] In an exemplary embodiment, the first position detection component 2 and the second position detection component 7 are set as photoelectric detection sensors.

[0033] Specifically, the photoelectric detection sensor has the advantages of convenient installation, high sensitivity, and easy operation.

[0034] In an exemplary embodiment, as Figures 3 to 4 shown, the first conveying component 1 can perform lifting motion, and the driving component 4 further includes a second driving component, and the second driving component provides power for the first conveying component 1 to perform lifting motion.

[0035] The second driving component is configured to: drive the first conveying component 1 to rise or fall when the plate 3 is stationary at the stop position 12.

[0036] Specifically, the first conveying component 1 can perform lifting motion, which is beneficial to the subsequent turning and diverting conveying of the plate 3. Figure 3 In the shown embodiment, the first conveying component 1 drives the plate 3 to perform a descending motion; Figure 4In the illustrated embodiment, when the sheet 3 leaves the first conveying assembly 1 and enters the third conveying assembly 8 for transmission, the first conveying assembly 1 performs a rising motion. It can be understood that the first conveying assembly 1 can also drive the sheet 3 to perform a rising motion so as to turn the sheet 3 and convey it to other conveying roller paths.

[0037] In an exemplary embodiment, as Figure 4 shown, the sheet feeding and conveying device 100 of the embodiment of the present application further includes a third conveying assembly 8, and the third conveying assembly 8 is located on the side of the first conveying assembly 1. The third conveying assembly 8 is arranged such that after the sheet 3 and the first conveying assembly 1 rise or fall together, the sheet 3 can enter the third conveying assembly 8 for conveying so as to turn and convey the sheet 3.

[0038] Specifically, the third conveying assembly 8 can be installed on one side or both sides of the first conveying assembly 1.

[0039] In an exemplary embodiment, the driving assembly 4 further includes a third driving assembly, and the third driving assembly is connected to the third conveying assembly 8. The third driving assembly is arranged to provide driving force for the third conveying assembly 8 to convey the sheet 3.

[0040] As Figures 2 to 4 shown, the embodiment of the present application provides a sheet production line 200, which includes the sheet feeding and conveying device 100 as described in the above exemplary embodiment, and further includes a dividing member 9. The dividing member 9 is located on the upstream side of the sheet 3 conveying direction of the second conveying assembly 5. The dividing member 9 is arranged to be able to cut the original sheet 10 into multiple sheets 3 distributed at intervals along the sheet 3 conveying direction. Optionally, the dividing member 9 can be arranged as a cutting tool assembly.

[0041] Specifically, the sheet production line 200 of the embodiment of the present application includes the sheet feeding and conveying device 100 as described in the above exemplary embodiment, and thus has the structural features and advantages of the sheet feeding and conveying device 100 as described in the above exemplary embodiment, which will not be elaborated here.

[0042] The original sheet 10 is a long sheet, and after passing through the dividing member 9, it can be divided into multiple sheets 3 with smaller lengths.

[0043] In an exemplary embodiment, the second conveying assembly 5 is arranged to be able to bring two adjacent sheets 3 entering the second conveying assembly 5 closer together and be able to accelerate the transmission of the sheets 3 distributed in pairs.

[0044] Specifically, after the original sheet 10 is divided by the dividing member 9, there is a small gap between adjacent sheets 3. Bringing the two sheets 3 closer together can eliminate the gap between the two sheets 3, which is beneficial for the conveying, turning management, and storage and stacking operations of the sheets 3. In Figure 4In the illustrated embodiment, two sheets 3 that are close to each other are conveyed on the third conveying assembly 8, facilitating the subsequent conveyance and storage stacking of the sheets 3. The second conveying assembly 5 accelerates the conveyance of the sheets 3, which can improve the conveyance efficiency of the sheets 3 and enable the sheets 3 to enter the first conveying assembly 1 relatively quickly.

[0045] It can be understood that the sheets 3 on the second conveying assembly 5 can be set to be accelerated and conveyed in a paired distribution state in various ways.

[0046] In an exemplary embodiment, as Figures 2 to 4 shown, the length of a single sheet 3 after being cut by the dividing member 9 is set to 7 meters, and the second conveying assembly 5 is set to include 5 sections of conveying roller paths. The lengths of the 5 sections of conveying roller paths arranged in sequence along the conveying direction of the sheets 3 are 1 meter, 2 meters, 4 meters, 4 meters, and 6 meters respectively. Each section of the conveying roller path of the second conveying assembly 5 can perform high-speed conveyance and low-speed conveyance. The speed of high-speed conveyance is about 260 meters per minute, and the speed of low-speed conveyance is about 94 meters per minute. Each section of the conveying roller path is provided with a conveying drive assembly that provides driving force for its conveyance. Each section of the conveying roller path is provided with its own third position detection assembly. The third position detection assembly can be set as a photoelectric detection sensor, and the third position detection assembly is set to be able to detect whether the tail of the sheet 3 on the corresponding conveying roller path has left the conveying roller path. The dividing member 9 cuts the original sheet 10 into multiple sheets 3 with a gap of 1 centimeter to 2 centimeters. Whenever the dividing member 9 performs two operations of cutting the original sheet 10, the conveying drive assemblies drive all the conveying roller paths to perform high-speed conveyance movements, which is beneficial for two adjacent sheets 3 to get close to each other. When the third photoelectric detection assembly detects that the tail of the sheet 3 on the corresponding conveying roller path has left the conveying roller path, the conveying drive assembly adjusts the corresponding conveying roller path from high-speed conveyance to low-speed conveyance, which is beneficial for widening the distance between the paired distributed sheet groups. The above embodiment can realize the paired distribution of the sheets 3 on the second conveying assembly 5 and perform high-speed conveyance movements.
