Description

Technical Field

[0001] The invention mainly relates to the field of paperboard conveying and sorting, and in particular to a paperboard cutting and collecting system. Background Art

[0002] Paperboard is widely used in various packaging, publicity, and even furniture, construction and other industries due to its rich variety and diverse performance. Among them, the largest application scenario of paperboard is the production of packaging boxes. After the corrugated paper core is made and the face paper is glued, the paperboard needs to be cut according to the size of the carton. The cutting of paperboard is done by a slitting machine, but the cardboard cut by the slitting machine will fly out at the subsequent discharge port, and the paperboard needs to be manually sorted, which is a great waste of human resources. At the same time, in the process of manual sorting, it is easy for the paperboard to bend and wear due to human operation, which affects the quality of subsequent products.

[0003] At present, there are corresponding paperboard conveying equipment and sorting and stacking equipment used in conjunction with the slitting machine, but these devices will eventually stack all the cut paperboards together. During the sorting process, it is very easy to cause the cut paperboards to be re-inserted and mixed, resulting in chaos and disorder of the paperboards, which is not conducive to subsequent collection and transportation. Therefore, these conveying and sorting equipment can usually only adapt to the situation where the number of paperboards cut is small. Once the paperboard is cut into more than 3 parts, these conveying and sorting equipment will have more errors and failures, and the subsequent separation and collection of paperboards will also become a problem, and it is impossible to improve efficiency. Summary of the invention

[0004] In order to solve the deficiencies of the prior art, the present invention provides a collection system for cardboard cuts, which realizes the automatic conveying and collection of multiple cut paperboards, can collect multiple cut paperboards separately, and improves processing efficiency.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] A cardboard slitting collection system includes a conveying mechanism and a sorting mechanism, wherein the conveying mechanism is connected downstream of a cardboard slitting machine. The conveying mechanism is used to convey the cardboard sheets slitting by the cardboard slitting machine, and finally the sorting mechanism is used to sort and stack the cardboard sheets.

[0007] The conveying mechanism has a plurality of single conveyor belts arranged in an array, and the single conveyor belts at even or odd positions have a longer conveying distance than the single conveyor belts adjacent thereto. Two pusher rollers are arranged above the ends of the single conveyor belts, and the two pusher rollers are arranged above the ends of the single conveyor belts at even positions and odd positions, respectively. Through the modular combination of the conveying mechanism, the paperboards after slitting can be conveyed separately, and the adjacent paperboards can be separated by the difference in length of the single conveyor belts at even positions and odd positions, so that they can be collected separately by the sorting mechanism.

[0008] The arranging mechanism includes a progressive track arranged below the end of the conveying mechanism and a bearing seat slidably arranged on the progressive track, the progressive track is parallel to the conveying direction of the conveying mechanism, a driving cylinder for pushing the bearing seat to slide back and forth is arranged at the end of the progressive track, two rows of arranging positions are arranged on the bearing seat, the two rows of arranging positions are arranged alternately, and the arranging positions correspond to the single conveyor belt one by one, lifting tracks and lifting drive mechanisms are arranged on both sides of the bearing seat, a lifting frame is slidably arranged in the lifting track, a pallet adapted to the arranging position is arranged on the lifting frame, and a A front positioning frame corresponding to the two columns of sorting positions, a front telescopic frame is slidably arranged on the front positioning frame, front positioning plates corresponding to the sorting positions are arranged on the front sides of the front telescopic frames, a front telescopic cylinder is arranged between the front positioning frame and the front telescopic frame, a C-shaped receiving groove is arranged on each of the sorting positions, the diameter of the top of the receiving groove is larger than the diameter of the bottom, the support plate is located in the receiving groove, side telescopic cylinders are arranged on both sides of the top of the receiving groove, the piston rod of the side telescopic cylinder passes through the side wall of the receiving groove and is exposed to the inside, and a side positioning plate is arranged at the front end of the piston rod of the side telescopic cylinder.

[0009] The sorting position of the present invention can collect the separated cardboards separately, so that the cardboards can be stably transported and stored after being collected, which is more convenient for continuous feeding of the next process.

[0010] Preferably, each of the single conveyor belts comprises a driving roller and a driven roller, and a belt body is tensioned between the driving roller and the driven roller; the driving roller of each single conveyor belt is coaxially driven, and a driving motor for driving the driving roller to rotate is arranged on one side of the conveying mechanism, and the even-numbered driven rollers are coaxially followed, and the odd-numbered driven rollers are coaxially followed.

[0011] Through the synchronous conveying single conveyor belt, it can be ensured that the cut paper boards are transported separately, thus providing a basis for the separate collection of the cut paper boards.

[0012] Preferably, the rotation speed of the push roller is 2-5 times the conveying speed of the single conveyor belt. The high-speed rotation of the push roller can play a certain role in pushing and accelerating the paperboard, so that the paperboard can be stably collected by the receiving groove.

[0013] Preferably, the top and bottom of the C-shaped accommodating groove are transitioned by a necking structure, and when the two telescopic cylinders are in an extended state, the distance between the two side positioning plates is adapted to the width of the bottom of the accommodating groove.

[0014] The size of the bottom of the receiving slot is slightly larger than the size of the paperboard, so that the paperboard can be collected in a limited position. The size of the top of the receiving slot is larger than the size of the bottom, so that more adjustment space can be provided after the paperboard is conveyed.

[0015] Preferably, a pair of baffles are arranged on the front side of the bottom of the accommodating groove, and the baffles are in sliding contact with the side edges of the accommodating groove. Closing cylinders for driving the baffles to slide are arranged on both sides of the accommodating groove.

[0016] The baffles on both sides of the receiving tank limit the paperboard inside the tank, preventing the paperboard from tipping over after collection, thereby ensuring stable collection of the paperboard in the receiving tank.

[0017] Preferably, the lifting frame is a frame structure, the front crossbeam of the lifting frame is located in front of the sorting position of the front row, the rear crossbeam of the lifting frame is located in front of the sorting position of the rear row, and the support plate is arranged on the front crossbeam and the rear crossbeam.

[0018] Preferably, the lifting drive mechanism is a screw mechanism driven by a servo motor, and the lifting frame is provided with a sliding pair that slides with the lifting track and a screw nut that cooperates with the screw mechanism, and the lifting drive mechanisms on both sides are lifted and lowered synchronously. The lifting frame can be lifted and lowered stably by the drive of the screw mechanism, so that the lifting frame can be slowly lowered to provide a collection space according to the stacking thickness of the paper board, thereby ensuring the stable collection of the paper board.

[0019] Preferably, the front telescopic cylinder drives the front positioning plate to vibrate back and forth, cooperating with the rear side of the accommodating groove to achieve the length direction positioning of the paper board, and the two side telescopic cylinders synchronously drive the side positioning plates to vibrate back and forth, achieving the width direction positioning of the paper board.

[0020] Through the vibration of the front positioning plate and the side positioning plate, the paperboard can be assembled so that the paperboard can be neatly stacked, which is beneficial to the subsequent paperboard transportation and the automatic feeding of the next process.

[0021] Preferably, the height of the accommodating groove is lower than the height of the single conveyor belt, a limit plate is arranged on the top of the rear baffle of the accommodating groove, the width of the limit plate is smaller than the width of the cardboard after slitting, and the height of the limit plate is higher than the height of the single conveyor belt.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The present invention designs a device that can automatically convey and collect paperboards that have been cut multiple times. It can shunt and regularize the paperboards that should be scattered after cutting, so that they can be neatly stacked and collected, which is more convenient for subsequent sorting, induction and use. This device is suitable for the cardboard cutting process in the preparation of small packaging boxes, which can greatly improve production efficiency, increase the degree of automation, reduce labor, and effectively reduce the damage to paperboards caused by manual sorting of paperboards, thereby ensuring the quality of subsequent packaging products.

[0024] The present invention creatively proposes a structure in which multiple single conveyor belts are staggered for conveying, so that adjacent paper boards can be separated during the conveying process, thereby realizing separate collection of paper boards.

[0025] The collecting device of the present invention comprises two staggered rows of collecting positions, on which receiving slots are installed, and paperboards can be sorted and stacked by setting the receiving slots. The present invention uses the reciprocating vibration of the cylinder to sort the paperboards in the width direction and the length direction, so that the paperboards can be neatly stored in the receiving slots. The paperboards are stably lowered and stored by the lifting action of the lifting frame, and the paperboards falling from the top are always kept at the same falling height, thereby standardizing the falling posture of the paperboards and maintaining the stability of the equipment operation.

[0026] The collecting device of the present invention can be moved. After the collection is completed, the collecting device can be moved out as a whole, and the sorted paper board can be transferred and stored as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0039] like Figure 1-10 As shown, the present invention provides a collection system for cardboard slitting, which is used to automatically collect and sort the boards cut by the cardboard slitting machine, so as to facilitate the transportation of paperboards and the automatic feeding of subsequent slotting, printing and other processes. The collection system mainly includes two units, a conveying mechanism 1 and a sorting mechanism 2, to realize the collection function of paperboards.

[0040] Conveying mechanism:

[0041] The conveying mechanism 1 is connected to the downstream of the cardboard slitting machine, and receives the cardboard cut by the slitting machine and conveys it downstream. The conveying mechanism 1 includes a conveying frame for installation, and the conveying frame has a plurality of single conveyor belts 11 arranged in an array, and the number of single conveyor belts 11 is consistent with the number of cardboards after slitting. The top surface of the conveying frame has a support plate to supplement the top belt body of the single conveyor belt 11, and the support plate is arranged on both sides of the single conveyor belt 11 to support the conveying of the cardboard, so as to ensure the stable conveying of the cardboard by the single conveyor belt 11, wherein the height of the single conveyor belt is slightly higher than the height of the support plate, thereby ensuring sufficient friction to ensure the stable conveying of the paperboard. The single conveyor belts 11 in the even or odd positions of the conveying mechanism 1 have a longer conveying distance than the single conveyor belts 11 adjacent to them, that is, the end extension of the single conveyor belt 11 is in a staggered state, which can separate the adjacent paperboards at the end, so that the paperboards can be collected separately, avoiding the overlap of multiple columns of paperboards when they are collected together and causing confusion.

[0042] Specifically, each single conveyor belt 11 includes a driving roller, a driven roller and a belt body. The driving roller and the driven roller are both rotatably mounted on the conveyor frame, and the belt body is tensioned between the driving roller and the driven roller. The driving roller of each single conveyor belt 11 is coaxially driven, and a driving motor for driving the driving roller to rotate is installed on one side of the conveyor frame. The driven rollers in the even-numbered positions move coaxially, and the driven rollers in the odd-numbered positions move coaxially, thereby ensuring stable and uniform speed transportation of the single conveyor belt 11.

[0043] The width of the support plate at the end of the single conveyor belt 11 with a longer conveying distance becomes narrower, thereby providing sufficient falling space for the paperboard falling from the single conveyor belt 11 with a shorter conveying distance, avoiding interference between the paperboard and the longer single conveyor belt 11 and affecting collection.

[0044] Furthermore, a gantry mounting frame is provided above the end of the single conveyor belt 11, and two push rollers 12 are rotatably installed on the gantry mounting frame. The two push rollers 12 are respectively provided above the ends of the single conveyor belt 11 at even positions and odd positions. The push rollers 12 are driven by a push motor, and the distance between the push rollers 12 and the single conveyor belt 11 is slightly smaller than the thickness of the paper board. The rotation speed of the push rollers 12 is 2-5 times the conveying speed of the single conveyor belt 11. Through the high-speed rotation of the push rollers 12, the paperboard can be driven to be quickly pushed to the collection position for collection and sorting at an instant, thereby ensuring the collection effect of the paper board after slitting.

[0045] Specifically, the push roller 12 above the shorter single conveyor belt 11 is not a continuous structure, but is disconnected at the position of the longer single conveyor belt 11 and is only connected by a drive shaft. The push roller 12 above the longer single conveyor belt 11 can also be designed as such a discontinuous structure, so that the paperboard pushed out from the shorter single conveyor belt 11 can fall more smoothly into the receiving groove 41 below.

[0046] Arrangement agency:

[0047] The sorting mechanism 2 includes a progressive track 3 arranged below the end of the conveying mechanism 1 and a support seat 21 slidably arranged on the progressive track 3. The progressive track 3 is parallel to the conveying direction of the conveying mechanism 1. The support seat 21 is used to carry and sort the paperboard, and also serves as an installation element for various components for sorting the paperboard. A driving cylinder 31 is arranged at the end of the progressive track 3 for pushing the support seat 21 to slide back and forth. The driving cylinder 31 is preferably a hydraulic cylinder. The support seat 21 can be driven to move back and forth stably by the push of the driving cylinder 31, so that the support seat 21 can be pushed to the end of the conveying mechanism 1 to receive the paperboard, and the support seat 21 can be pushed away from the conveying mechanism 1 to transfer the paperboard.

[0048] Specifically, two rows of sorting positions 4 are installed on the bearing seat 21. The two rows of sorting positions 4 are staggered. The staggered structure can avoid interference between adjacent sorting positions 4, thereby ensuring the effective acceptance and sorting of paperboard. The sorting positions 4 correspond to the single conveyor belt 11 one by one. The single conveyor belt 11 conveys the paperboard to the end so that it falls into the sorting position 4. A C-shaped receiving groove 41 is set on each sorting position 4, and the opening direction of the receiving groove 41 faces the single conveyor belt 11. The diameter of the top of the receiving groove 41 is larger than the diameter of the bottom, so that the board can be guided to a certain extent after falling into the receiving groove 41. The top and bottom of the receiving groove 41 are transitioned by a tapered channel. The size of the bottom of the receiving groove 41 is slightly larger than the size of the board to avoid interference and wear or jamming of the board. The thickness of the top of the receiving groove 41 is smaller than the thickness of the bottom, and the thickness of the top of the receiving groove 41 is smaller than the length of the board, providing space for subsequent board regularization.

[0049] The height of the receiving groove 41 is lower than the height of the single conveyor belt 11, so that the cut paperboard can smoothly fall into the receiving groove 41 and be collected. A limit plate 411 is installed on the top of the rear baffle of the receiving groove 41. The width of the limit plate 411 is smaller than the width of the cut paperboard, and the height of the limit plate 411 is higher than the height of the single conveyor belt 11. The limit plate 411 is used to block the falling paperboard to a certain extent, preventing the paperboard from falling to the outside of the receiving groove 41.

[0050] Specifically, a pair of baffles 44 are provided at the front side of the bottom of the receiving groove 41, and a slideway assembly for limiting the baffles 44 is installed on the side wall of the receiving groove 41, so that the baffles 44 are in sliding contact with the side of the receiving groove 41. Closing cylinders 45 for driving the baffles 44 to slide are installed on both sides of the receiving groove 41. Through the extension of the closing cylinders 45, the baffles 44 can slide relative to the side of the receiving groove 41, thereby realizing the state of partially closing or completely opening the bottom of the receiving groove 41. When storing paperboards, the baffles 44 block and limit the two sides of the opening direction of the receiving groove 41 to prevent the paperboards from falling out. When the paperboards need to be transferred and collected after storage, the baffles 44 are opened to fully expose the opening of the receiving groove 41, so as to facilitate the complete export of the paperboards after sorting.

[0051] In order to stably receive the paperboard and ensure that each paperboard can be at a stable height after falling, the present invention provides a lifting receiving unit. Specifically, lifting rails 22 and lifting drive mechanisms 23 are installed on both sides of the bearing seat 21. The lifting rails 22 serve as guide components, and a pair of lifting rails 22 on each side are symmetrically arranged. The lifting drive mechanism 23 serves as an action component. Specifically, the lifting drive mechanism 23 is a screw mechanism driven by a servo motor, and the driving screw is installed between the lifting rails 22. A lifting frame 5 is slidably arranged in the lifting rail 22. A sliding pair that slides with the lifting rail 22 and a screw nut that cooperates with the screw mechanism are arranged on the lifting frame 5. Through the drive of the servo motor, the stable lifting of the lifting frame 5 can be achieved by utilizing the cooperation of the driving screw and the screw nut. The lifting drive mechanisms 23 on both sides are lifted and lowered synchronously to ensure the smooth operation of the lifting frame 5. A support plate 51 that is adapted to the sorting position 4 is arranged on the lifting frame 5, and the support plate 51 is located in the receiving groove 41. The size of the support plate 51 is slightly smaller than the size of the receiving slot 41 of the sorting position 4 , so that when the support plate 51 moves up and down, there is no significant interference with the receiving slot 41 .

[0052] Specifically, the lifting frame 5 is a frame structure, the front crossbeam of the lifting frame 5 is located in front of the sorting position 4 in the front row, and the rear crossbeam of the lifting frame 5 is located in front of the sorting position 4 in the rear row. The support plate 51 is arranged on the front crossbeam and the rear crossbeam, so that the support plate 51 is a cantilever structure.

[0053] The descent of the lifting frame 5 is detected by the sensor, and the sensor detects the height of the paper board in at least one receiving slot 41. Through the feedback of the detection signal, the controller controls the lifting frame 5 to slowly descend, so that the top paper board is always at the same height, ensuring that the falling height of the paper board is consistent, and further ensuring the falling posture of the paper board.

[0054] The bearing seat 21 is provided with a front positioning frame 24 corresponding to the two rows of sorting positions 4, and a telescopic sleeve is symmetrically arranged on the top of the front positioning frame 24, and the axis of the telescopic sleeve is perpendicular to the sorting position 4. The front telescopic frame 241 is slidably installed in the telescopic sleeve, and the front positioning plates 242 corresponding to the sorting positions 4 are arranged on the front sides of the front telescopic frame 241, and the front telescopic cylinder 243 is arranged between the front positioning frame 24 and the front telescopic frame 241. Through the telescopic action of the front telescopic cylinder 243, the front telescopic frame 241 can be driven to vibrate stably forward and backward, and then the paperboard is pushed and sorted through the front positioning plate 242, and the rear side of the paperboard collides with the rear side of the receiving groove 41, and finally the paperboard is sorted in the length direction. Side telescopic cylinders 42 are installed on both sides of the top of the receiving groove 41, and the piston rod of the side telescopic cylinder 42 passes through the side wall of the receiving groove 41 and is exposed inside, and the front end of the piston rod of the side telescopic cylinder 42 is provided with a side positioning plate 43. The side telescopic cylinders 42 reciprocate and telescope at the same frequency, and use the two side positioning plates 43 to position the paperboard in the width direction. When the two side telescopic cylinders 42 are in the extended state, the distance between the two side positioning plates 43 is slightly smaller than the width of the bottom of the receiving groove 41, so that as the paperboard continues to fall, the paperboard is assembled and can be stored in the receiving groove 41 below after being arranged.

[0055] This system can realize the automatic separate collection of paperboard after multiple slitting. After the paperboard slitting machine slits the paperboard, the slit paperboard enters the conveying mechanism 1 of the present invention for conveying, and the adjacent paperboards are still conveyed in a parallel state. Until the end of the conveying mechanism 1, due to the inconsistency of the lengths of the adjacent single conveyor belts 11, the shorter single conveyor belt 11 first throws out the paperboard it conveys under the action of the push roller 12, and then leaves the parallel state.

[0056] The ejected paperboard falls into the corresponding receiving slot 41. As the lifting frame 5 gradually descends, the paperboard also gradually descends in the receiving slot 41, and then passes through the area of ​​the side telescopic cylinder 42 and the front telescopic cylinder 243, and is arranged by two correspondingly arranged side positioning plates 43 and the front positioning plates 242, so that the paperboard is neatly stacked in the receiving slot 41.

[0057] After the lifting frame 5 descends to the bottom, the transportation of the paper board is stopped, and the support seat 21 is separated from the bottom of the conveying mechanism 1 under the push of the driving cylinder 31, so that the accommodating groove 41 is farther away from the single conveyor belt 11, so that the paper board can be collected and transported more conveniently.
