Description

Technical Field

[0001] The invention relates to the field of carton forming devices, in particular to a servo paper pushing and tidying device. Background Art

[0002] A box gluing machine is a machine that can make paper boxes (boxes) by automatically creasing, gluing, hooking the bottom, folding and other processes on cardboard after color printing, paper mounting and die cutting. In the box gluing and folding machine, in order to produce a larger volume of cartons, it is necessary to use a larger size of blank box paper, and the production of larger blank box paper in production requires the use of larger die-cutting and box gluing and folding machine equipment. Because large-scale die-cutting and box gluing equipment has the same principle and similar structure as small equipment, if manufacturers purchase large-scale die-cutting and box gluing equipment simply to produce larger cartons, it will inevitably cause repeated introduction of equipment, reduce the utilization rate of a single device, and increase the purchase cost of the equipment, which is very uneconomical. For this reason, in the box making process, two pieces of paper made by a small die-cutting machine are often used, and they are automatically docked in the production process after being glued by a gluing device to achieve the blank paper size required for making large boxes, thereby saving the investment in equipment costs. In order to ensure that the paper can be made into a paper box with straight corners and beautiful appearance after docking, it should be corrected and positioned horizontally and vertically during the paper docking process to achieve horizontal alignment and vertical parallelism, and keep the angle between the vertical and horizontal edges. For this reason, some corresponding mechanisms or devices are used in the current machines to correct and position the paper vertically and horizontally. The most commonly used ones are chain-type paper pushing claws to transport the paper vertically, and fixed left and right support plates to correct and position the paper horizontally.

[0003] In the production process, in order to ensure that the folded paperboard can be made into a paper box with straight corners and beautiful appearance, the outer folding belts on both sides and the straight edges of the left and right support boards are used to correct the paper when folding. However, due to the slippage between the conveyor belt and the paper surface or other reasons, in the actual paper transportation process, due to the poor correction ability of the straight edge of the support board, a trumpet-shaped defect is easily formed at the folding position, thereby reducing the qualified rate of the product.

[0040] Working principle: The conveyor belt conveys a stack of cardboards to the bottom of the overall device, and the relative distance between the paper pushing module 2 and the paper blocking module 3 is adjusted through the gantry frame 1 to match the size of the cardboard. The height of the paper blocking component is adjusted through the second height adjusting component to make the paper blocking component located in front of the cardboard and block all the cardboards. The height of the paper pushing component is adjusted through the first height adjusting component to make the paper pushing component contact the rear end faces of all the cards on duty above the bottom cardboard of the cardboard layer, and then the cardboard is pushed forward through the gantry frame 1 to align the upper cardboard with the bottom cardboard, completing the cardboard tidying action.

[0041] This scheme conveys a stack of cardboards to the bottom of the overall device through a conveyor belt, adjusts the relative distance between the paper push module 2 and the paper stop module 3 through the gantry frame 1 to match the size of the cardboard, adjusts the height of the paper stop component through the second height adjustment component, makes the paper stop component located in front of the cardboard and blocks all the cardboards, adjusts the height of the paper push component through the first height adjustment component, makes the paper push component contact the rear end faces of all the cardboards above the lowest cardboard layer of the cardboard layer, pushes the cardboard forward through the gantry frame 1, aligns the upper cardboard with the lowest cardboard, and completes the cardboard neatening operation. The front end face of the cardboard is positioned through the paper stop component, and the rear end face of the cardboard is pushed through the paper push component so that the front end face of the cardboard contacts the paper stop component, achieving the neat operation of the cardboard, positioning and correcting the cardboard interface position, accurate positioning, precise correction, and a fairly good repair effect on the bell mouth defects in the carton manufacturing process, improving the product yield rate and reducing costs.

[0042] As a preferred embodiment, Figure 2-3 As shown, the paper pushing component includes a first servo motor 201, a paper pushing fixing plate 202, a first active synchronous wheel 203, a first passive synchronous wheel 207, a paper pushing and aligning belt 205 and a paper pushing board 206;

[0043] The paper pushing fixed plate 202 is connected to the first height adjusting component, the first servo motor 201 is fixed on one side of the paper pushing fixed plate 202, the first active synchronous wheel 203 is driven and connected to the first servo motor 201, the first passive synchronous wheel 207 is rotatably fixed on the paper pushing fixed plate 202, the first active synchronous wheel 203 drives the first passive synchronous wheel 207 through the paper pushing and aligning belt 205, the lower end edge of the paper pushing and aligning belt 205 is parallel to the conveyor belt, the paper pushing paper board 206 is vertically fixed on the outer side of the paper pushing and aligning belt 205, and the paper pushing and aligning belt 205 rotates along the first clockwise direction.

[0044] Specifically, the paper pushing component further includes a first pad 204, which is located above the lower edge of the paper pushing and aligning belt 205, contacts the upper surface of the lower edge of the paper pushing and aligning belt 205, and is horizontally fixed on the paper pushing fixing plate 202. There are multiple paper pushing plates 206, each of which is fixed on the outer side of the paper pushing and aligning belt 205 at equal intervals.

[0045] The paper pushing component is adjusted to a suitable height by the first height adjusting component, and then the first servo motor 201 drives the first active synchronous wheel 203, and in combination with the first passive synchronous wheel 207, the first active synchronous wheel 203 drives the paper pushing and aligning belt 205 to rotate along the first clockwise direction. The first clockwise rotation means that when the paper pushing paperboard 206 moves to the bottom of the paper pushing and aligning belt 205, its moving direction is the same as the moving direction of the paperboard on the conveyor belt. The paperboard is pushed forward by the paper pushing paperboard 206.

[0046] At the same time, a first pad 204 is arranged above the lower end of the paper pushing and aligning belt 205, which can effectively reduce the shaking of the paper pushing and aligning belt 205 during transmission, make the paper pushing paper board 206 better fit the paper board, and improve the accuracy of the paper board aligning action.

[0047] As a preferred embodiment, Figure 4-5 As shown, the paper stopper component includes a second servo motor 301, a paper stopper fixing plate 302, a second active synchronous wheel 303, a second passive synchronous wheel 307, a paper stopper and paper alignment belt 305 and a paper pusher 306;

The second pad 304 is horizontally fixed on the paper stop fixing plate 302.

[0050] The paper stopper is moved to a suitable height by the paper stopper fixing plate 302, and then the second servo motor 301 drives the second active synchronous wheel 303, and the second active synchronous wheel 303 drives the paper stopper and paper aligning belt 305 to rotate in the opposite direction of the first clockwise direction in combination with the second passive synchronous wheel 307. The rotation in the opposite direction of the first clockwise direction means that when the paper stopper 306 moves to the bottom of the paper stopper and paper aligning belt 305, its moving direction is opposite to the moving direction of the paperboard on the conveyor belt. The front end of the paperboard is blocked and positioned by the paper stopper 306, and the paperboard pusher 206 is cooperated to realize the neat movement of the paperboard.

[0051] At the same time, a second pad 304 is arranged above the lower end of the paper stopper and paper aligning belt 305, which can effectively reduce the shaking of the paper stopper and paper aligning belt 305 during transmission, make the paper stopper 306 fit the paperboard better, and improve the accuracy of the paperboard aligning action.

[0053] The driving motor 215 is fixed on the module fixing seat 208 and drives the driven sprocket 210. The driven sprocket 210 can be rotatably fixed on the module fixing seat 208. The driven sprocket 210 drives the first adjusting screw 209 to move in the vertical direction. The fixed plate 211 is fixed at the lower end of the first adjusting screw 209, and the paper pushing component is connected to the fixed plate 211; the guide fixed plate 214 is fixed below the module fixing seat 208, the first slider 212 is fixed on the guide fixed plate 214, the first linear slide rail 213 is slidably connected to the first slider 212, the first linear slide rail 213 is connected to the paper pushing component, and the first linear slide rail 213 moves in the vertical direction.

[0054] The second height adjustment component also includes a dislocation fixing seat 216 for dislocating the paper pushing component and the paper blocking component in the horizontal direction. The dislocation fixing seat 216 is fixed on the guide fixing plate 214 , and the first sliding block 212 is fixed on the dislocation fixing seat 216 .

[0055] The driven sprocket 210 is driven to rotate by the driving motor 215, thereby driving the first adjusting screw 209 to move up and down in the vertical direction. At the same time, a fixed plate 211 is fixedly connected to the lower end of the first adjusting screw 209, and the paper pushing module and the paper blocking module are respectively fixed on the fixed plate 211, so that they move up and down with the first adjusting screw 209, thereby realizing the vertical position adjustment of the paper pushing module and the paper blocking module.

[0057] Specifically, the gantry frame 1 includes a column 101, a transverse beam 102, a longitudinal beam 103, a second linear slide rail 104 and a second slide block 105;

[0058] The column 101 is vertically fixed at both ends of the transverse beam 102, and the column 101 is perpendicular to the ground. The second linear slide rail 104 is fixed above the transverse beam 102. The second slider 105 is fixed at both ends of the longitudinal beam 103. The second slider 105 is slidably connected to the second linear slide rail 104. The second slider 105 is provided with a braking mechanism for determining the relative position of the second slider 105 and the second linear slide rail 104.

[0059] A paper pushing and lateral movement component 106 is provided at one end of the longitudinal beam 103, and a paper stopping and lateral movement component 107 is provided at the other end.

The screw nut 112 can be rotatably connected to the second adjusting screw 109. The paper pushing module 2 and the paper blocking module 3 are respectively fixed on the screw nut 112. The third linear slide rail 111 is fixed on one side of the longitudinal beam 103. The paper pushing module 2 and the paper blocking module 3 are both provided with a third slider, and the third slider is slidably connected to the third linear slide rail 111.

[0061] The second slider 105 fixed below the longitudinal beam 103 slides along the second linear slide rail 104 fixed above the transverse beam 102 to adjust the transverse position of the paper push module and the paper stop module, and the second adjusting lead screw 109 is driven to rotate by the adjusting motor 108, so as to drive the lead screw nut 112 provided on the second adjusting lead screw 109 to move longitudinally, that is, the paper push component is driven to move longitudinally by the paper push transverse moving component 106, and the paper stop component is driven to move longitudinally by the paper stop transverse moving component 107. Thus, the position adjustment of the paper push module and the paper stop module in the horizontal direction is realized.

[0062] At the same time, a third linear slide rail 111 is set on one side of the longitudinal beam 103, which cooperates with the third slider on the paper pushing module 2 and the paper blocking module 3 to guide the paper pushing module 2 and the paper blocking module 3 when they move longitudinally, ensuring the stability and accuracy of the movement.

[0063] This embodiment also provides a more specific embodiment, which is:

[0064] A servo paper pushing and tidying device, such as Figure 1 As shown, it includes a fixed gantry frame 1, a paper pushing module 2 and a paper blocking module 3.

[0065] like Figure 1-6As shown, the fixed gantry frame is composed of a column, a transverse beam, and a longitudinal beam; a second linear slide rail is fixed on the upper plane of the transverse beam, which is connected to the longitudinal beam through a second slider (sliding left and right), so that the longitudinal beam can slide left and right on the transverse beam through the second slider (sliding left and right).

[0066] The end plates are fixed to the two ends of the longitudinal beam, and the second adjusting screw (front and back) is fixed to the inner side of the end plate through the screw flange. The second adjusting screw (front and back) is connected to the adjusting motor fixed to the outer side of the end plate. The adjusting motor drives the second adjusting screw (front and back) to rotate, and drives the screw nut fixed on the module fixing seat to move forward and backward (along the axial direction of the screw), thereby realizing the front and rear position adjustment of the paper pushing module and the paper blocking module on the third linear slide rail.

[0067] like Figure 2-3 As shown, the paper push module includes a guide fixing plate, a module fixing seat, a paper push fixing plate, a paper push aligning belt, a first servo motor, etc. The driven sprocket and the flange are combined through a rolling bearing; the bottom end of the first adjusting screw (lifting) is fixed to the fixing plate through the screw flange, and the fixing plate is connected to the paper push fixing plate; the shaft end of the driving motor is equipped with a driving sprocket, which drives the driven sprocket through the chain to drive the lifting and lowering of the first adjusting screw (lifting) to achieve the up and down adjustment of the paper push fixing plate. The guiding of the paper push fixing plate is achieved by fixing the first linear slide rail thereon and the slider (sliding up and down) fixed on the guide fixing plate.

[0068] The paper pushing and aligning components include a paper pushing fixed plate, a first active synchronous wheel, a first passive synchronous wheel, a first pad, and a paper pushing and aligning belt; the first active synchronous wheel and the first passive synchronous wheel are fixedly mounted on the paper pushing fixed plate, the first active synchronous wheel is mounted on the shaft end of the first servo motor, the paper pushing and aligning belt is wrapped around the first active synchronous wheel and the first passive synchronous wheel, and three paper pushing boards are equidistantly arranged on the paper pushing and aligning belt. Installing the pad can reduce the jitter of the paper pushing and aligning belt during operation and improve the accuracy of paper aligning.

[0069] The speed of the paper pushing and aligning belt is controlled by the first servo motor, and the paper pushing board is used to push the upper paperboard of the carton at a short distance at a high speed, and the paper blocking and aligning belt are used to correct the position in the conveying direction to ensure the alignment of the interface position. The paper pushing board can be one, two or three pieces.

[0070] like Figure 4-5As shown, the paper stop module includes a guide fixing plate, a module fixing seat, a paper stop fixing plate, a paper stop paper alignment belt, a second servo motor, etc. The driven sprocket and the flange are combined through a rolling bearing; the bottom end of the adjusting screw (lifting) is fixed to the fixing plate through the screw flange, and the fixing plate is connected to the paper push fixing plate (paper stop fixing plate); the driving motor shaft end is equipped with an active sprocket, which drives the driven sprocket through the chain to drive the adjusting screw (lifting) to move up and down, so as to achieve the up and down adjustment of the paper stop fixing plate. The guiding of the paper stop fixing plate is achieved by fixing the first linear slide rail thereon and the first slider (sliding up and down) on the offset fixing seat. The offset fixing seat fixed on the guide fixing plate makes the lateral relative positions of the paper push paper alignment belt and the paper stop paper alignment belt staggered, which increases the box sample range of paper box processing, and the height of the cardboard that can be made can be reduced to 60mm.

[0071] The paper stop and paper alignment components include a paper stop fixing plate, a second active synchronous wheel, a second passive synchronous wheel, a second pad, and a paper stop and paper alignment belt; the second active synchronous wheel and the second passive synchronous wheel are fixedly mounted on the paper stop fixing plate, the second active synchronous wheel is mounted on the shaft end of the second servo motor, the paper stop and paper alignment belt is wrapped around the second active synchronous wheel and the second passive synchronous wheel, and two push paper boards are equidistantly arranged on the paper stop and paper alignment belt. Installing the pad can reduce the jitter of the paper stop and paper alignment belt during operation and improve the paper alignment accuracy.

[0072] The speed of the paper stopper and paper alignment belt is controlled by the second servo motor, and the paper stopper is used to block the upper and lower paperboards of the paper box in the vertical direction. The paper pusher and paper alignment belt are used to correct the position in the conveying direction to ensure the alignment of the interface position. The paper pusher module and paper stopper module are moved according to the size and shape of the paper. Accurate correction and positioning can be achieved for papers of different shapes and sizes, reducing the occurrence of bell-mouth defects, improving the qualified rate of paper boxes, and making the product quality stable.
