Description

Technical Field

[0001] The invention relates to the field of carton production equipment, and in particular to a cardboard extraction device and a cardboard extraction method. Background Art

[0002] In carton production, it is usually necessary to extract the corresponding cardboard or carton for inspection. Through spot inspection, we can timely understand the processing status of carton production, and then make corrections in time to reduce losses. For example: extract the cardboard after printing and check the printing status, extract the cardboard after the cardboard passes through the die-cutting machine and check the die-cutting status, or extract the carton after the cardboard passes through the gluer and check the folding status.

[0003] In the existing carton production line, when spot checks are required, the only way is to manually remove the cardboard from the carton production line for inspection, which is very inconvenient. In addition, the carton production line runs at a high speed during production, so the carton production line needs to be shut down or the running speed needs to be reduced, resulting in reduced production efficiency. When the position of the extracted cardboard or carton is at the rear end of the counter, the extracted cardboard or carton has been counted in the total number of cartons produced by the production line, and the corresponding number will not be automatically subtracted after the cardboard or carton is extracted, resulting in counting errors.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a cardboard extraction device and a cardboard extraction method, aiming to solve the inconvenience caused by the need for manual extraction of cardboard or cartons in the existing carton production line.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A cardboard extraction device comprises a frame and a cardboard conveying assembly connected to the frame, a driving assembly is also connected to the frame, an output end of the driving assembly is connected to a guide plate, and the frame is provided with a guide strip behind the guide plate.

[0008] In the cardboard extraction device, the middle part of the guide plate is rotatably connected to the frame, and one end of the guide plate is hinged to the output end of the driving component, and the driving component is a telescopic cylinder.

[0009] In the cardboard extraction device, a counter is fixed on the frame, and the counter is electrically connected to the controller.

[0010] In the cardboard extraction device, a negative pressure component is fixed on the frame, the bottom surface of the cardboard conveying component is a conveying plane, and the conveying plane of the cardboard conveying component is arranged at the air inlet of the negative pressure component.

[0011] In the cardboard extraction device, a cardboard storage bracket is provided between the guide strip and the guide plate, the cardboard storage bracket is placed below the cardboard conveying assembly, and the guide strip is fixed on the cardboard storage bracket.

[0012] In the cardboard extracting device, a conveying belt structure is provided on the cardboard storage bracket.

[0013] In the cardboard extraction device, the negative pressure component is further connected with an adjustable paper guide strip between the guide strip and the guide plate, both sides of the adjustable paper guide strip are rotatably connected to the negative pressure component, and both sides of the adjustable paper guide strip are provided with adjustment screws.

[0014] In the cardboard extraction device, connecting plates are fixed on both sides of the negative pressure component, arc-shaped grooves are arranged on both sides of the connecting plates, and the adjusting screws are placed in the arc-shaped grooves.

[0015] A cardboard extraction method using the cardboard extraction device is characterized by comprising the following steps:

[0016] S001: Input the number of cardboards to be extracted into the controller;

[0017] S002: When the counter no longer detects the cardboard, the controller controls the driving assembly to drive the guide plate to move so that the cardboard is pushed onto the guide strip;

[0018] S003: When the counter detects that the cardboard has passed the input number and the counter does not detect the cardboard, the controller controls the driving component to drive the guide plate to reset, so that the subsequent cardboard is transported by the cardboard transport component.

[0019] In the cardboard extraction method using the cardboard extraction device, a conveyor belt structure is provided on the cardboard storage bracket. After step S002 or S003, the controller controls the conveyor belt structure to move to convey the cardboard out of the frame.

[0020] Beneficial effects: By arranging a frame, a cardboard conveying assembly, a driving device, a guide plate and a guide strip in a carton production line, the driving assembly can drive the guide plate to move or swing, so that the guide plate switches between two states: contact with the cardboard and non-contact with the cardboard. When the carton production line is working normally, the guide plate is in a non-contact state with the cardboard. When the cardboard needs to be extracted, the driving assembly drives the guide plate to protrude on the conveying plane of the cardboard conveying assembly, and then the cardboard passing through the cardboard conveying assembly contacts the guide plate and is guided to the guide strip by the guide plate, thereby realizing automatic extraction of the cardboard. It is convenient and simple, and will not cause a decrease in production efficiency.

[0021] In addition, when the bottom surface of the cardboard conveying assembly is used as the conveying plane, a conveyor belt structure is arranged under the cardboard conveying assembly, so that after the pulled out cardboard falls on the conveyor belt structure, the conveyor belt structure conveys it to the outside of the frame for easy taking; after the controller controls the pulling out of the corresponding number of cardboards, the corresponding number of cardboards can be automatically subtracted from the total number of cardboards, thereby preventing counting errors.

DETAILED DESCRIPTION

[0029] The present invention provides a cardboard extraction device and a cardboard extraction method. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0030] See also Figure 1-5 A cardboard extraction device includes a frame 110 and a cardboard conveying assembly 120 connected to the frame 110, a driving assembly 140 is also connected to the frame 110, a guide plate 150 is connected to the output end of the driving assembly 140, and the frame 110 is provided with a guide bar 161 behind the guide plate 150. The frame 110 and the cardboard conveying assembly 120 are connected to a carton production line, and the cardboard passes through the cardboard conveying assembly 120 during the production process, that is, it is conveyed by the cardboard conveying assembly 120.

[0031] The driving component 140 is arranged in the middle of the cardboard conveying component 120, and the driving component 140 can drive the guide plate 150 to move or rotate, so that the guide plate 150 switches between the two states of contact with the cardboard and non-contact with the cardboard. When the carton production line is working normally, the guide plate 150 is in a state of not contacting the cardboard. When the cardboard needs to be extracted, the driving component 140 drives the guide plate 150 to protrude on the conveying plane of the cardboard conveying component 120, and then the cardboard passing through the cardboard conveying component 120 contacts the guide plate 150 and is guided by the guide plate 150 to the guide strip 161, so that the cardboard is extracted.

[0032] In the process of cardboard extraction, since part of the cardboard is still in contact with the cardboard conveying assembly 120, the cardboard conveying assembly 120 can push the cardboard to move onto the guide bar 161 to complete the cardboard extraction. In this structure, when it is necessary to extract the cardboard for inspection, it is only necessary to control the driving assembly 140 to automatically extract the cardboard, which is convenient and simple, and the guide bar 161 can guide the cardboard to the outside of the frame 110 for easy removal.

[0033] In the above, both ends of the guide bar 161 are connected to the frame 110, and a space for the cardboard to pass through is reserved between the middle of the guide bar 161 and the cardboard conveying assembly 120, that is, when the cardboard is normally conveyed on the production line, the cardboard passes between the cardboard conveying assembly 120 and the guide bar 161, and when the guide plate 150 guides the cardboard, the cardboard is guided to the side of the guide bar 161 away from the cardboard conveying assembly 120.

[0034] In practical applications, when the top surface of the cardboard conveying assembly 120 is used as the conveying plane, the guide bar 161 is arranged above the cardboard conveying assembly 120, and a conveying assembly for taking the cardboard out of the frame 110 may also be arranged on the guide bar 161. The frame 110 and the cardboard conveying assembly 120 may also be the frame 110 and the conveying structure of a certain device on a carton production line.

[0035] In a preferred embodiment, the driving assembly 140 is a telescopic cylinder, the middle portion of the guide plate 150 is rotatably connected to the frame 110, and one end of the guide plate 150 is hinged to the output end of the driving assembly 140. When the telescopic cylinder is in a retracted state, the guide plate 150 is in a non-contact position with the paperboard. When the piston rod of the telescopic cylinder is extended, the guide plate 150 is driven to swing, so that one end thereof protrudes outside the driving assembly 140, and then a side surface of the guide plate 150 forms a guide plane to guide the paperboard onto the guide strip 161.

[0036] In a preferred embodiment, a counter 180 is fixed on the frame 110. The counter 180 is located at the guide plate 150. The counter 180 is electrically connected to a controller. The counter 180 is used to count the number of cardboards. The controller can be a control system of the production line. When in use, the counter 180 generates a signal when it detects a cardboard. After the cardboard passes, the corresponding signal disappears. Therefore, it is also used to identify the position between adjacent cardboards. When the cardboard needs to be pulled out, the controller controls the driving assembly 140 to extend when the guide plate 150 is located between adjacent cardboards.

[0037] In the above, after the controller controls the corresponding number of cardboards to be drawn out, the controller can automatically subtract the corresponding number of cardboards from the total number of cardboards, thereby preventing counting errors.

[0038] In a preferred embodiment, a negative pressure assembly 130 is fixed on the frame 110, and the bottom surface of the cardboard conveying assembly 120 is a conveying plane, and the conveying plane of the cardboard conveying assembly 120 is arranged at the air inlet of the negative pressure assembly 130. Specifically, the conveying plane refers to a surface for conveying cardboard, and the cardboard conveying assembly 120 can be an existing belt conveying group, which includes a transmission roller and a plurality of belts connected to the transmission roller, and the guide plate 150 is located between two adjacent belts; the negative pressure assembly 130 includes a bellows and a fan, and both the bellows and the fan are fixed on the frame, and the bellows is inside the belt arranged in the belt conveying group, and an air inlet is opened on the side facing the conveying plane of the cardboard conveying assembly 120, and the bellows is connected to the fan through a pipeline, and when the fan is working, negative pressure is formed in the bellows and at the air inlet, so that the cardboard conveyed on the cardboard conveying assembly 120 is close to the conveying plane of the cardboard conveying assembly 120 under the action of negative pressure, so that the cardboard can be conveyed on the bottom surface of the cardboard conveying assembly 120, and the accuracy of cardboard conveying can also be improved.

[0039] In practical applications, guide plates 150 may be provided between two adjacent belts, and all guide plates 150 are rotatably connected to the bellows via a rotating shaft. Since the bellows is fixed on the frame, the guide plates 150 are rotatably connected to the frame.

[0040] In a preferred embodiment, when the bottom surface of the cardboard conveying assembly 120 is a conveying plane, a cardboard storage bracket 160 may be provided between the guide bar 161 and the guide plate 150, and the cardboard storage bracket 160 is placed below the cardboard conveying assembly 120, and the guide bar 161 is fixed on the cardboard storage bracket 160. When the cardboard is pulled out, the pulled out cardboard is guided to the cardboard storage bracket 160 by the guide bar 161, and is placed on the cardboard storage bracket 160 under the action of gravity, so that the exported cardboard is placed, and the cardboard can be directly taken from the cardboard storage bracket 160 when checking the cardboard.

[0041] In order to facilitate the taking out of the cardboard, a conveyor belt structure 162 is provided on the cardboard storage bracket 160. The conveyor belt structure 162 can convey the cardboard to the outside of the frame 110. The conveyor belt structure 162 can be an existing belt conveyor structure.

[0042] In the above, the cardboard storage support 160 can be a shelf placed on the cardboard conveying assembly 120, and the guide bar 161 can be fixed on the shelf.

[0043] In a preferred embodiment, the negative pressure assembly 130 is further connected with an adjustable paper guide strip 170 between the guide strip 161 and the guide plate 150. Both sides of the adjustable paper guide strip 170 are rotatably connected with the negative pressure assembly 130, and both sides of the adjustable paper guide strip 170 are provided with adjustment screws 112. The adjustable paper guide strip 170 is provided between the guide strip 161 and the guide plate 150. The adjustable paper guide strip 170 can swing around the rotation connection position with the frame 110, and then the distance between the two ends of the adjustable paper guide strip 170 and the paperboard conveying assembly 120 can be adjusted to adapt to the passage of paperboards of different thicknesses. After the adjustable paper guide strip 170 is adjusted to a suitable position, the adjustment screws 112 are tightened to fix the adjustable paper guide strip 170 on the frame 110.

[0044] In actual use, connecting plates 113 are fixed on both sides of the negative pressure component 130, and the connecting plates 113 are provided with arc-shaped grooves 111. The adjusting screws 112 are placed in the arc-shaped grooves 111. When the adjusting screws 112 are rotated, the nut of the adjusting screws 112 can be pressed on the frame 110 to fix the adjustable paper guide strip 170. The adjusting screws 112 can also be rotated in the reverse direction so that the adjusting screws 112 can move in the arc-shaped grooves 111, thereby adjusting the adjustable paper guide strip 170.

[0045] See also Figure 6 A cardboard extraction method using the cardboard extraction device comprises the following steps:

[0046] S001: Input the number of cardboards to be extracted into the controller.

[0047] S002: When the counter 180 no longer detects the cardboard, the controller controls the driving assembly 140 to drive the guide plate 150 to move so that the cardboard is pushed onto the guide strip 161. When the counter 180 no longer detects the cardboard, the guide plate 150 is located between two adjacent cardboards. Therefore, when the cardboard is pulled out, the guide plate 150 will not abut against the cardboard that has partially passed the guide strip 161.

[0048] S003: When the counter 180 detects that the cardboard has passed the input number and the counter 180 does not detect the cardboard, the controller controls the driving component 140 to drive the guide plate 150 to reset, complete the cardboard extraction work, and make the subsequent cardboard be transported by the cardboard transport component 120.

[0049] In a preferred embodiment, a conveyor belt structure 162 is provided on the cardboard storage support 160. After step S002 or S003, the controller controls the conveyor belt structure 162 to move and convey the cardboard out of the frame 110 to facilitate taking the cardboard.

[0050] In the present invention, by arranging a frame 110, a cardboard conveying assembly 120, a driving device, a guide plate 150 and a guide strip 161 in a carton production line, the driving assembly 140 can drive the guide plate 150 to move or swing, so that the guide plate 150 switches between two states of contact with the cardboard and non-contact with the cardboard. When the carton production line is working normally, the guide plate 150 is in a non-contact state with the cardboard. When the cardboard needs to be extracted, the driving assembly 140 drives the guide plate 150 to protrude on the conveying plane of the cardboard conveying assembly 120, and then the cardboard passing through the cardboard conveying assembly 120 contacts the guide plate 150 and is guided to the guide strip 161 by the guide plate 150, thereby realizing automatic extraction of the cardboard, which is convenient and simple.

[0051] In addition, when the bottom surface of the cardboard conveying assembly 120 is used as the conveying plane, a conveying belt structure 162 is set below the cardboard conveying assembly 120, so that after the extracted cardboard falls on the conveying belt structure 162, the conveying belt structure 162 is conveyed to the outside of the frame 110 for easy removal.
