Abstract
Description
Technical Field
[0001] The utility model relates to the field of feeding mechanisms, and specifically refers to a feeding mechanism for wood-based panels. Background Art
[0002] Before wood-based panels are made into artificial composite boards, they need to be dried by a drying device. Multiple drying layers are arranged in the drying device for single-piece drying of the boards, so as to improve the drying speed and efficiency. Before that, it is necessary to separate the boards stacked in a board stack piece by piece through a feeding mechanism and then load them into the conveying mechanism piece by piece.
[0003] At present, the existing feeding mechanism transports the board stack to the lifting frame. After adsorbing the wood-based panel on the top layer of the board stack by several suction cups, it is lifted and fed into the conveying mechanism. During this process, the thickness of the board stack gradually decreases, and the lifting frame is gradually adjusted to rise so that several suction cups can adsorb the wood-based panel. However, such a setting makes the lifting frame in a high position when the next batch of board stacks needs to be fed. It is necessary to wait for the lifting frame to descend in place before the next batch of board stacks can be transported to the lifting frame. This results in the inability to continuously supplement the board stacks, and the feeding mechanism cannot continuously feed, reducing the feeding efficiency of the feeding mechanism. During the time of waiting for the lifting frame to supplement the next batch of board stacks, the rest of the equipment is in a standby state, resulting in a large amount of energy loss and cost waste.
[0004] Designing a feeding mechanism for wood-based panels to solve the problems existing in the above-mentioned prior art is the purpose of the research of the present utility model. Summary of the Utility Model
[0005] In view of the problems existing in the above-mentioned prior art, the present utility model provides a feeding mechanism for wood-based panels, which can effectively solve the problems existing in the above-mentioned prior art.
[0006] The technical solution of the present utility model is as follows:
[0007] A feeding mechanism for wood-based panels, comprising:
[0008] A frame, the inner bottom of which is provided with a lifting frame driven by a lifting drive device to lift. A plurality of first-level board stacks are arranged side by side on the lifting frame. A transverse movement frame driven by a transverse movement drive device to move horizontally is arranged in the frame. A plurality of material taking mechanisms for taking the board pieces of the plurality of first-level board stacks piece by piece are arranged on the transverse movement frame;
[0009] The stacking mechanism comprises a plurality of stacking pieces which are spaced apart and located below the plurality of material-retrieving mechanisms and are laterally located outside the two sides of the plurality of primary plate stacks, and a stacking driving device for driving the plurality of stacking pieces to move laterally. The frame is provided with a stacking detection device whose detection head is located between the plurality of material-retrieving mechanisms and the stacking pieces. After the lifting frame rises until it is detected by the stacking detection device, the stacking driving device drives the stacking pieces on both sides to move laterally toward each other to the bottom of both ends of the plurality of primary plate stacks to receive the plurality of primary plate stacks, and the lifting frame descends and resets.
[0010] Furthermore, the stacking drive device includes a plurality of stacking slide rails, a plurality of connecting parts and a plurality of stacking cylinders which are symmetrically arranged on the left and right sides of the frame and respectively correspond to the left and right ends of the plurality of stacking parts. The upper ends of the connecting parts are slidably connected to the corresponding stacking slide rails, the telescopic ends of the stacking cylinders are respectively connected to the corresponding upper ends of the connecting parts, and the stacking parts are stacking rollers which are rotatably connected to the lower ends of the connecting parts relative to each other at the left and right ends.
[0011] Furthermore, the frame is provided with a stacking detection device with a detection head located at the lower side of the stacking piece; the lifting drive device drives the lifting frame to descend and reset to fill a number of secondary plate stacks and then rise; when the upper ends of the several secondary plate stacks are detected by the stacking detection device, the stacking drive device drives the stacking rollers on the front and rear sides to move in opposite directions and roll away from the several primary plate stacks, so that the several primary plate stacks are overlapped on the several secondary plate stacks.
[0012] Furthermore, the front side of the frame corresponds to the feed end of the corresponding conveying device, and a material stopper is provided inside the front side of the frame. The rear part of the material stopper includes, from bottom to top, a material stopper portion which is vertically arranged and corresponds to the upper part of the plurality of the stacking parts, and a guide portion which is inclined and has a front end higher than a rear end, the front end of the guide portion corresponds to the feed end, and the height of the material stopper portion corresponds to the thickness of the plurality of primary plate stacks received by the plurality of the stacking parts.
[0013] Further, a plurality of the material taking mechanisms are arranged side by side on the transverse moving frame and respectively correspond to a plurality of the first-level sheet stacks. The material taking mechanism includes a plurality of suction cup groups, a loading driving device arranged on the transverse moving frame and used for driving the plurality of suction cup groups to lift, and a fixed frame arranged below the transverse moving frame and connected to the telescopic end of the loading driving device in the middle. The upper ends of the plurality of suction cup groups are connected to the fixed frame. A loading detection device with a detection head located below the suction cup groups is arranged on the machine frame; when the lifting frame rises to the upper ends of the plurality of first-level sheet stacks and is detected by the loading detection device, the loading driving device drives the fixed frame to drive the plurality of suction cup groups to descend to evenly adsorb the sheet pieces on the uppermost layer of the corresponding first-level sheet stacks and then move upward. The plurality of material taking mechanisms drive the sheet pieces from back to front to be butted against the feeding ends of the corresponding conveying mechanisms under the drive of the transverse moving frame.
[0014] Further, a stock preparation frame corresponding to the lifting frame is arranged on one outer side of the machine frame. Transfer chains that are butt-jointed are respectively arranged on the lifting frame and the stock preparation frame. Stack changing driving devices used for driving the corresponding transfer chains to rotate left and right are respectively arranged on the lifting frame and the stock preparation frame.
[0015] Further, the machine frame includes columns arranged at the four corners. Guide openings corresponding to the four corners of the lifting frame are arranged on the four columns. The lifting driving device includes pulleys slidably arranged up and down in the four guide openings, and a plurality of chain and sprocket assemblies that connect the four pulleys and are driven by a lifting motor to drive the four pulleys to slide up and down. The four pulleys are respectively connected to the lifting frame, and the plurality of chain and sprocket assemblies are arranged inside the frame body of the machine frame.
[0016] Therefore, the present utility model provides the following effects and / or advantages:
[0017] 1. Through the cooperation between the stack receiving mechanism and the stack receiving detection device in this application, after the lifting frame rises to be detected by the stack receiving detection device, the stack receiving driving device drives the stack receiving members on both sides to move horizontally towards each other to the bottoms of both ends of a plurality of first-level sheet stacks to receive the plurality of first-level sheet stacks, and then the lifting frame descends and resets. Thus, after the material taking mechanism continuously takes materials piece by piece, the thickness of the plurality of first-level sheet stacks gradually decreases, and the lifting frame gradually rises until the lifting frame is higher than the stack receiving members. The plurality of first-level sheet stacks can be temporarily received by the stack receiving members, so that the lifting frame can descend and reset to load a plurality of second-level sheet stacks and then rise for feeding, shortening the time for the plurality of second-level sheet stacks to rise to the in-place position after filling, that is, shortening the feeding efficiency of the lifting frame to the material taking mechanism after switching the first-level sheet stack on the lifting frame to the second-level sheet stack, realizing the continuous feeding of the lifting frame to the material taking mechanism, and further enabling the material taking mechanism to continuously load the sheet pieces into the conveying device, improving the overall feeding efficiency of the feeding mechanism, and avoiding the situation of wasting energy and cost when other equipment waits for the lifting frame to replenish a plurality of second-level sheet stacks and standby.
[0018] 2. The stacking component of this application is a stacking roller whose left and right ends are respectively rotatably connected to the lower ends of the opposite connecting components. It can be manually adjusted to rise after the lifting frame descends and resets to fill the second-level sheet stack, until it rises to near the bottom of the two stacking rollers at the upper end of the second-level sheet stack. Then, control the stacking driving device to drive the stacking rollers on the front and rear sides to move in opposite directions and roll away from several first-level sheet stacks, so that several first-level sheet stacks are stacked on several second-level sheet stacks, thereby realizing the integration of the remaining sheet pieces of several first-level sheet stacks and the second-level sheet stack. At this time, the lifting frame continues to rise to the position for several suction cup groups to adsorb the sheet pieces. This makes the switching between the first-level sheet stack and the second-level sheet stack on the lifting frame faster, and the feeding distance between the lowermost sheet piece of the first-level sheet stack and the uppermost sheet piece of the second-level sheet stack basically does not occupy extra time. Therefore, the continuous feeding effect of the lifting frame on the material taking mechanism is further improved, and the overall feeding efficiency of the feeding mechanism is further improved. Moreover, by setting the stacking component as a roller, in addition to avoiding scratching the sheet pieces when rolling away from the first-level sheet stack, it can also prevent the first-level sheet stack from being driven and offset when the two stacking rollers move in opposite directions, improving the alignment of the first-level sheet stack stacked on the second-level sheet stack. At the same time, the setting of the above structure can stack several first-level sheet stacks on the second-level sheet stack before the thickness of several first-level sheet stacks on the two receiving rollers becomes too thin, thus avoiding the situation where the thickness of several first-level sheet stacks on the two receiving rollers is too thin, resulting in a decrease in the rigidity of the first-level sheet stack and collapse, and further causing damage or dropping of the sheet pieces and affecting the feeding process of the feeding mechanism. On the premise of improving the feeding efficiency of the feeding mechanism, the stability of the stacking mechanism for temporarily receiving materials is improved, ensuring stable and efficient feeding.
[0019] 3. After the stacking component of this application temporarily receives several first-level sheet stacks, the guiding part guides the uppermost sheet piece adsorbed by several suction cup groups and transported forward for feeding into the feeding end of the conveying device. At the same time, the baffle part blocks the remaining sheet pieces from shifting forward to ensure the stability of the subsequent feeding of several first-level sheet stacks temporarily received on the stacking component, and avoid the situation where the first-level sheet stack moves forward, resulting in the inability of several suction cup groups to adsorb and transport.

[0027] For the convenience of those skilled in the art to understand, the structure of the present utility model will be further described in detail with reference to the accompanying drawings in the embodiments:
[0028] Refer to Figure 1-6 , a feeding mechanism for wood-based panels, comprising:
[0029] A frame 1, with a lifting frame 11 driven to lift by a lifting drive device 12 provided at the inner bottom. A plurality of first-level panel stacks 8 are arranged side by side on the lifting frame 11, and the front and rear ends of the plurality of first-level panel stacks 8 are suspended; specifically, there are several levels of panel stacks, which are lifted step by step by the lifting frame 11 for feeding. A transverse moving frame 13 driven to move back and forth by a transverse moving drive device 131 is provided inside the frame 1. A plurality of material taking mechanisms 2 for taking materials from the panel sheets of the plurality of first-level panel stacks 8 one by one are provided on the transverse moving frame 13; specifically, the transverse moving drive device 131 includes transverse moving sliders connected to the left and right ends of the transverse moving frame 13 and drive cylinders such as cylinders for driving the transverse moving sliders to move transversely.
[0030] The stacking mechanism 3 includes a plurality of stacking pieces 31 which are spaced apart and located below the plurality of material-retrieving mechanisms 2 and are laterally located outside the two sides of the plurality of primary plate stacks 8, and a stacking driving device 32 for driving the plurality of stacking pieces 31 to move laterally. The frame 1 is provided with a stacking detection device 14 whose detection head is located between the plurality of material-retrieving mechanisms 2 and the stacking pieces 31. After the lifting frame 11 rises and is detected by the stacking detection device 14, the stacking driving device 32 drives the stacking pieces 31 on both sides to move laterally toward each other to the bottom of the two ends of the plurality of primary plate stacks 8 to receive the plurality of primary plate stacks 8, and the lifting frame 11 descends and resets. Specifically, the plurality of stacking pieces 31 extend left and right and correspond to the front and rear outer sides of the plurality of primary plate stacks 8, respectively. The stacking detection device 14 can be set as a photoelectric sensor, etc. The plurality of stacking pieces 31 are arranged in parallel in the transverse direction. The degree can be adaptively adjusted according to specific circumstances. In this embodiment, the height of the two is controlled to be less than one hundred sheets on each first-level sheet stack 8 on the lifting frame 11 after the lifting frame 11 is raised to the point where it is detected by the stacking detection device 14; after the lifting drive device 12 drives the lifting frame 11 to rise into place, several of the material-picking mechanisms 2 absorb the sheet sheets on the top layer of several sheet stacks through several suction cup groups 21 and then feed them to the feeding end of the corresponding conveying mechanism. As the feeding proceeds, the thickness of several sheet stacks gradually decreases and the height of the lifting frame 11 gradually increases. Until the lifting frame 11 rises to the point where it is detected by the stacking detection device 14, the stacking drive device 32 drives the stacking members 31 on the front and rear sides to move toward each other to the bottom of the front and rear ends of several first-level sheet stacks 8 for receiving several first-level sheet stacks 8, and the lifting drive device 12 drives the lifting frame 11 to descend and reset.
[0031] With the arrangement of the above structure, after the material picking mechanism 2 continuously picks up materials piece by piece, the thickness of several primary plate stacks 8 gradually decreases, and the lifting frame 11 gradually rises until the lifting frame 11 is higher than the stacking piece 31, several primary plate stacks 8 can be temporarily received by the stacking piece 31, so that the lifting frame 11 can be lowered and reset to load several secondary plate stacks 9 and then rise to feed materials, thereby shortening the time for several secondary plate stacks 9 to rise into place after filling, that is, shortening the efficiency of feeding the material picking mechanism 2 after the lifting frame 11 switches from the primary plate stack 8 to the secondary plate stack 9, realizing the continuous feeding of the lifting frame 11 to the material picking mechanism 2, and then the material picking mechanism 2 can continuously feed the plate pieces into the conveying mechanism, thereby improving the overall feeding efficiency of the feeding mechanism, and avoiding the situation where other equipment is on standby while waiting for the lifting frame 11 to replenish several secondary plate stacks 9, thereby wasting energy and cost.
[0032] In order to further improve the overall feeding efficiency of the feeding mechanism, the stack receiving driving device 32 includes a plurality of stack receiving slide rails 321, a plurality of connecting members 322, and a plurality of stack receiving cylinders 323 that are symmetrically arranged inside the left and right sides of the frame 1 and respectively correspond to the left and right ends of a plurality of the stack receiving members 31. The upper ends of the connecting members 322 are slidably connected to the corresponding stack receiving slide rails 321, and the telescopic ends of the stack receiving cylinders 323 are respectively connected to the upper ends of the corresponding connecting members 322. The stack receiving members 31 are stack receiving rollers whose left and right ends are respectively rotatably connected to the lower ends of the opposite connecting members 322. Specifically, the number of the stack receiving rollers is set to two distributed front and back, the number of the stack receiving slide rails 321 is set to four, the number of the connecting members 322 is set to four, and the number of the stack receiving cylinders 323 is set to four, and they respectively correspond to the left and right ends of the two stack receiving rollers.
[0033] With the above structure, it can be realized by manual adjustment that after the lifting frame 11 descends and resets to fill the secondary sheet stack 9 and then rises until it rises to a position close to the bottom of the two stack receiving rollers at the upper end of the secondary sheet stack 9, the stack receiving driving device 32 is controlled to drive the stack receiving rollers on the front and back sides to move in opposite directions and roll away from a plurality of primary sheet stacks 8, so that a plurality of primary sheet stacks 8 are stacked on a plurality of secondary sheet stacks 9, thereby realizing the integration of the remaining sheet pieces of a plurality of primary sheet stacks 8 and the secondary sheet stack 9. At this time, the lifting frame 11 continues to rise to the in-place position for a plurality of suction cup groups 21 to adsorb the sheet pieces. This makes the switching between the primary sheet stack 8 and the secondary sheet stack 9 on the lifting frame 11 faster, and the feeding distance between the lowermost sheet piece of the primary sheet stack 8 and the uppermost sheet piece of the secondary sheet stack 9 basically does not take up extra time. Therefore, the continuous feeding effect of the lifting frame 11 on the material taking mechanism 2 is further improved, and the overall feeding efficiency of the feeding mechanism is further improved. Moreover, by setting the stack receiving member 31 as a roller, in addition to avoiding scratching the sheet pieces when rolling away from the primary sheet stack 8, it can also prevent the primary sheet stack 8 from being driven and offset when the two stack receiving rollers move in opposite directions, improving the alignment of the primary sheet stack 8 stacked on the secondary sheet stack 9;
[0034] At the same time, with the above structure, a plurality of primary sheet stacks 8 on the two receiving rollers can be stacked on the secondary sheet stack 9 before their thickness becomes too thin, thereby avoiding the situation where the thickness of a plurality of primary sheet stacks 8 on the two receiving rollers becomes too thin, resulting in a decrease in the rigidity of the primary sheet stack 8 and collapse, and further leading to damage or dropping of the sheet pieces and affecting the feeding process of the feeding mechanism. On the premise of improving the feeding efficiency of the feeding mechanism, the stability of the stack receiving mechanism 3 for temporarily receiving materials is improved, ensuring stable and efficient feeding.
[0035] In order to improve the overall automation level of the loading mechanism and reduce the labor cost, a stacking detection device 15 with a detection head located below the stacking member 31 is provided on the frame 1. Specifically, the stacking detection device 15 can be set as a position switch corresponding to the lifting frame 11, etc.; the lifting drive device 12 drives the lifting frame 11 to descend and reset to load a number of secondary sheet stacks 9 and then ascend. When the upper ends of a number of the secondary sheet stacks 9 are detected by the stacking detection device 15, the stacking drive device 32 drives the stacking rollers on both the front and rear sides to move in opposite directions and roll away from a number of the primary sheet stacks 8, so that a number of the primary sheet stacks 8 are stacked on a number of the secondary sheet stacks 9. Thus, the automatic control of the above actions is realized through the setting of the stacking detection device 15, and further the overall automation level during the operation of the loading mechanism is improved to reduce the labor cost. When necessary, manual adjustment can be made when there is a large deviation after the primary sheet stacks 8 are stacked on the secondary sheet stacks 9.
[0036] In order to ensure the loading stability of a number of the material taking mechanisms 2 after adding the stacking mechanism 3 to achieve the above technical effects, the front side of the frame 1 corresponds to the feeding end of the corresponding conveying mechanism. A material blocking member 4 is provided inside the front side of the frame 1. The rear part of the material blocking member 4 successively includes a material blocking portion 41 arranged vertically and corresponding to the upper part of a number of the stacking members 31, and a guiding portion 42 arranged obliquely with the front end higher than the rear end. The front end of the guiding portion 42 corresponds to the feeding end, and the height of the material blocking portion 41 corresponds to the thickness of a number of the primary sheet stacks 8 carried by a number of the stacking members 31. Thus, after the stacking members 31 temporarily carry a number of the primary sheet stacks 8, the guiding portion 42 guides the uppermost sheet pieces adsorbed and forwardly transported by a number of the suction cup groups 21 to enter the feeding end of the conveying mechanism. At the same time, the material blocking portion 41 blocks the remaining sheet pieces from shifting forward, so as to ensure the subsequent loading stability of a number of the primary sheet stacks 8 temporarily carried on the stacking members 31, and avoid the situation that the forward movement of the primary sheet stacks 8 causes the failure of a number of the suction cup groups 21 to adsorb and transport.
[0037] In order to further improve the overall automation level of the loading mechanism and reduce labor costs, several of the material taking mechanisms 2 are arranged side by side on the cross - moving frame 13 and respectively correspond to several of the first - level sheet stacks 8. The material taking mechanism 2 includes several suction cup groups 21, a loading driving device 22 arranged on the cross - moving frame 13 and used to drive the several suction cup groups 21 to lift and lower, and a fixed frame 23 arranged below the cross - moving frame 13 and connected to the telescopic end of the loading driving device 22 in the middle. The upper ends of the several suction cup groups 21 are connected to the fixed frame 23. Specifically, the loading driving device 22 is set as a driving cylinder such as a cylinder. An upper - material detection device 16 with a detection head located below the suction cup group 21 is arranged on the machine frame 1. Specifically, the upper - material detection device 16 can be set as a photoelectric sensor, etc. When the lifting frame 11 rises to the position where the upper ends of the several first - level sheet stacks 8 are detected by the upper - material detection device 16, the loading driving device 22 drives the fixed frame 23 to drive the several suction cup groups 21 to descend to evenly adsorb the sheet pieces on the uppermost layer of the corresponding first - level sheet stacks 8 and then move upward. The several material taking mechanisms 2 drive the sheet pieces from back to front to dock with the feeding ends of the corresponding conveying mechanisms under the drive of the cross - moving frame 13. Thus, through the addition of the upper - material detection device 16, the lifting in - place of the lifting frame 11 is automatically detected to control the material taking mechanism 2 to take materials, improving the overall automation level of the loading mechanism and reducing labor costs.
[0038] In order to further improve the switching between the first - level sheet stacks 8 and the second - level sheet stacks 9 on the lifting frame 11, a stock - preparation frame 5 corresponding to the lifting frame 11 is arranged on one outer side of the machine frame 1. Oppositely - connected conveyor chains 6 (not shown in the figure) are respectively arranged on the lifting frame 11 and the stock - preparation frame 5. Stack - changing driving devices 7 used to drive the corresponding conveyor chains 6 to rotate left and right are respectively arranged on the lifting frame 11 and the stock - preparation frame 5. Specifically, the stack - changing driving device 7 is set as a motor with an output end linked to the conveyor chain 6 through a chain and a sprocket. Thus, through the arrangement of the stock - preparation frame 5 and the two conveyor chains 6, when the lifting frame 11 fills with several first - level sheet stacks 8 and rises in - place for loading, several second - level sheet stacks 9 can be pre - filled onto another conveyor chain 6 on the stock - preparation frame 5 in advance. After several stack - receiving members 31 temporarily receive several first - level sheet stacks 8 and the lifting frame 11 descends and resets, the several second - level sheet stacks 9 are horizontally conveyed to the lifting frame 11 through the two conveyor chains 6, so that the lifting frame 11 can quickly fill with several second - level sheet stacks 9 and then rise for continuous loading, further improving the switching speed between the first - level sheet stacks 8 and the second - level sheet stacks 9 on the lifting frame 11 and enabling the loading speed of the loading mechanism to be further increased.
[0039] Specifically, the frame 1 includes columns 17 provided at four corners. Guide openings 171 corresponding to the four corners of the lifting frame 11 are provided on the four columns 17. The lifting drive device 12 includes pulleys 121 that slide up and down in the four guide openings 171, and a number of chain and sprocket assemblies 122 that connect the four pulleys 121 and are driven by a lifting motor to drive the four pulleys 121 to slide up and down. The structure of the chain and sprocket assemblies 122 is prior art and not the main inventive point of this embodiment, so it will not be described in detail here. The four pulleys 121 are respectively connected to the lifting frame 11, and a number of the chain and sprocket assemblies 122 are provided inside the frame body of the frame 1.
[0040] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
