Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal palletizing equipment, specifically to a continuous sheet metal conveying and palletizing line. Background Technology

[0002] After logs are processed into veneers by a planer, the veneers need to be dried and stacked before they can enter the plywood composite processing. Currently, after drying, workers usually collect the veneers into stacks for easy transport to the next plywood composite site for processing. To facilitate transfer and storage, traditional plywood stacking methods mainly rely on manual stacking. Although the stacking quality is good, the overall efficiency is very low and the labor intensity is high.

[0003] To address this issue, patent CN111153223A discloses a board stacking device. This device can continuously unload and stack boards, achieving good stacking results and high efficiency. However, because this patent only has one stacking station, its efficiency is limited by the transfer speed of the already stacked boards at the station during normal board loading and stacking operations. In the aforementioned solution, whether loading is done manually or by external equipment, the boards are not classified according to surface quality. This results in inconsistent quality in the stacked boards, severely impacting subsequent secondary processing. To ensure the quality of stacked boards, the industry currently relies on manual loading, where the surface quality of the boards is differentiated and classified before qualified boards are fed into the stacking equipment. The entire material loading process is extremely inefficient. During the loading process, workers need to constantly check and flip the loading pallets, resulting in high labor intensity. Furthermore, manual loading cannot be integrated with existing automatic loading equipment, thus slowing down the loading speed and hindering the overall palletizing efficiency of the palletizing line.

A vision inspection device visually inspects the sheets conveyed by the mechanism, facilitating the identification of the surface quality of the sheets.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] Reference Figures 1 to 5 The diagram illustrates a continuous sheet metal conveying and palletizing line, comprising a conveying mechanism 100, a vision inspection device 200, a material distribution device 300, a sheet metal receiving and palletizing device 400, several external delivery devices 500, and a control device. The conveying mechanism 100 has two interchangeable output ends. The vision inspection device 200 performs visual inspection on the sheet metal conveyed by the conveying mechanism 100. The material distribution device 300 is connected to any one of the output ends of the conveying mechanism 100. The material distribution device 300 is equipped with a swinging clamping mechanism 310. The sheet metal receiving and palletizing device 400 has multiple receiving mechanisms 410, and the input ends of all receiving mechanisms 410 can connect to the swinging clamping mechanism 310. The output end is adapted to receive the board skins output by the swing clamping mechanism 310; the receiving and stacking device 400 is provided with a lifting and stacking mechanism 420 in the area below each receiving mechanism 410, and the lifting and stacking mechanism 420 is used to receive the board skins discharged by the receiving mechanism 410; a number of external delivery devices 500 are respectively provided below all the lifting and stacking mechanisms 420 to receive the board skins discharged by the lifting and stacking mechanism 420; the control device can control the switching of the two output ends on the conveying mechanism 100, the swing clamping mechanism 310, the lifting and stacking mechanism 420 and the receiving mechanism 410 according to the detection results of the vision detection device 200.

[0028] In this application, the conveying mechanism 100 can be a conventional conveyor belt, its main purpose being to load the plywood. The visual inspection device 200 in this application is a conventional CCD camera and its supporting system, its main purpose being to detect and identify the surface quality of the plywood conveyed by the conveying mechanism 100, such as identifying surface features like cracks, voids, wood pores, and missing parts. This design facilitates the classification of plywood, which is beneficial for subsequent processing. Furthermore, in this application, the control device can be a conventional programmable control board and its supporting system, such as CN103350908A-Automatic Packaging Palletizing Control System and Palletizing System, CN103863831B-Mixed Palletizing Production Line Device and Palletizing System, or CN107512546B-A Control System or Controller Used in a Conveying System and Conveying Method, etc. These are not detailed here, as they are existing conventional technologies.

[0029] This continuous conveying and palletizing line for sheet metal utilizes a conveyor mechanism 100 to receive sheet metal sheets fed manually or by external feeding equipment. A vision inspection device 200 visually inspects the sheet metal conveyed by the conveyor mechanism 100 to easily identify the surface quality of the conveyed sheet metal sheets. The conveyor mechanism 100 has two interchangeable output ends. This design allows the control device to directly send out unqualified sheet metal sheets from one output end of the conveyor mechanism 100 based on the results of the vision inspection device 200, preventing unqualified sheet metal sheets from entering the sorting device 300. The sorting device 300 classifies sheet metal sheets of different quality specifications and sends them to different receiving mechanisms 410. This allows for the classified stacking of sheet metal sheets of different quality specifications, facilitating subsequent classification, transfer, and use, and improving ease of use. An external conveying device 500 transports the stacked sheet metal sheets received by the receiving mechanism 410 outwards, facilitating transfer and handling by external equipment.

[0030] See Figures 1 to 2In order to achieve the conveying of sheet metal and the accurate coordination of the material distribution device 300 and the visual inspection device 200, in one embodiment of this application, the conveying mechanism 100 includes a main frame 110. An input conveyor belt 120 and a detection conveyor belt 130 are sequentially arranged on one side of the main frame 110. The visual inspection device 200 is located on the main frame 110 above the detection conveyor belt 130. A material distribution frame 140 is hinged to the end of the main frame 110 at the outlet of the detection conveyor belt 130. A waste rejection drive belt 150 is provided, which is connected to the detection conveyor belt 130. An adjusting member 160 is provided on the main frame 110 for adjusting the swing of the material distribution frame 140. The input conveyor belt 120, the detection conveyor belt 130, the adjusting member 160 and the waste rejection drive belt 150 are all electrically connected to the control device. The control device can control the adjusting member 160 to drive the material distribution frame 140 to move between the first station and the second station, so that the output end of the waste rejection drive belt 150 can be connected or disconnected from the input end of the material distribution device 300.

[0031] In the above embodiments, the waste removal conveyor belt 150, the input conveyor belt 120, and the inspection conveyor belt 130 actually constitute a three-section conveying structure, which allows for adjustment of the conveying speed to adapt to different conveying needs. Specifically, to facilitate inspection and reduce the impact of errors in the inspection environment, the inspection conveyor belt 130 is a single piece of conveyor belt, allowing the entire sheet to be completely contained within it, which is beneficial for the visual inspection device 200 to perform inspection and identification. The waste removal conveyor belt 150 and the input conveyor belt 120 are both structures composed of multiple belts, which reduces operating costs, and the perforated gaps facilitate the falling off of dust or debris from the sheet. It should be noted that, in this application, since the input conveyor belt 120 and the detection conveyor belt 130 have different working requirements and require different conveying speeds, they are driven by separate motors. The waste removal transmission belt 150 is mainly for connecting the detection conveyor belt 130 and the input end of the material distribution device 300, so its conveying speed requirement is not high. In this application, the waste removal transmission belt 150 can directly share a transmission roller with the detection conveyor belt 130 for transmission, that is, both are wound around the same transmission roller, and then the transmission roller is driven to rotate by a motor. Thus, a single motor can be used to drive both the waste removal transmission belt 150 and the detection conveyor belt 130 simultaneously.

[0032] In the above embodiments, when the vision inspection device 200 detects and identifies that the sheet metal conveyed on the inspection conveyor belt 130 is unqualified, the control device directly controls the adjusting component 160 to drive the adjusting sorting rack 140 to swing, so that the reject conveyor belt 150 is disconnected from the input end of the sorting device 300. At this time, the unqualified sheet metal is automatically conveyed out by the reject conveyor belt 150 and will not enter the sorting device 300, ensuring that all the sheet metal stacked on the entire palletizing line is qualified. Conversely, if the vision inspection device 200 detects and identifies that the sheet metal conveyed on the inspection conveyor belt 130 is qualified, the control device directly controls the adjusting component 160 to drive the adjusting sorting rack 140 to swing, so that the reject conveyor belt 150 is connected to the input end of the sorting device 300. At this time, the sheet metal on the inspection conveyor belt 130 enters the sorting device 300 through the reject conveyor belt 150 for the next step. It should be noted that when the vision inspection device 200 detects and identifies the sheets conveyed on the conveyor belt 130, in addition to identifying whether the sheets are qualified, it also classifies the qualified sheets, which is beneficial for the subsequent sorting and stacking by the material distribution device 300 and the receiving and stacking device 400. The classification of qualified sheets can be divided into first-grade, second-grade, and qualified products, etc. The classification is mainly based on the number and size of defects on the sheets. Since this classification method is not the focus of this application, it will not be described in detail here.

[0033] See Figure 2 , Figure 3 and Figure 4 To facilitate the conveying of sheet metal to the input ends of different receiving mechanisms 410, in one embodiment of this application, the material distribution device 300 includes a frame 320, a first clamping mechanism 330, and a transmission mechanism 340. The first clamping mechanism 330 is mounted on the frame 320, and its input end is connected to any one of the output ends of the conveying mechanism 100. The swinging clamping mechanism 310 is swingably mounted on the frame 320, and the side of the swinging clamping mechanism 310 that is fitted with the frame 320 is connected to the output end of the first clamping mechanism 330. The transmission mechanism 340 is mounted on the frame 320 and provides power to the first clamping mechanism 330 and the swinging clamping mechanism 310. The transmission mechanism 340 is electrically connected to a control device.

[0034] In the above embodiments, the first clamping mechanism 330 can be a conventional double-belt clamping structure, which mainly receives the sheet metal conveyed by the waste removal transmission belt 150. The transmission mechanism 340 in this application can be a conventional motor-chain structure. For example, in one embodiment of this application, the transmission mechanism 340 includes a transmission motor 341 and a transmission chain 342. The transmission motor 341 is mounted on the frame 320, and the output end of the transmission motor 341 is connected to the power input end of the first clamping mechanism 330 and the swing clamping mechanism 310 through the transmission chain 342. The transmission motor 341 is electrically connected to the control device.

[0035] See Figure 3 and Figure 4 In one embodiment of this application, the swinging clamping mechanism 310 includes a drive assembly, a swing frame 311, and a clamping assembly disposed on the swing frame 311. The drive assembly is mounted on the frame 320. The swing frame 311 is rotatably mounted on the frame 320 at the feeding end of the clamping assembly. The power output end of the clamping assembly is connected to the transmission mechanism 340, and the output end of the clamping assembly is compatible with the input end of the pallet stacking device 400. The drive assembly can drive the swing frame 311 to swing around its rotation point with the frame 320. The drive assembly is electrically connected to a control device. In this embodiment, the main purpose of the drive assembly is to drive the swing frame 311 to rotate around its hinge point with the frame 320 or a swing shaft structure. Therefore, in actual use, a conventional telescopic electric cylinder or similar structure can be used for driving the swing, or a cam-linkage structure can be used, or a motor can drive a gear on the rotation shaft of the swing frame 311. However, due to the relatively complex environment in which this equipment is used, with a lot of dust and sawdust, this application does not adopt telescopic electric cylinders. Some structures are difficult to use for a long time.

[0036] In the above-described improved embodiment, to improve service life and ease of use, the drive assembly includes a first motor 312, a first reducer 313 connected to the output end of the first motor 312, and a first drive shaft 314 rotatably mounted on the frame 320. The output end of the first reducer 313 is connected to the first drive shaft 314. At least one end of the first drive shaft 314 is provided with a first sprocket, and a first chain 315 is wound around the first sprocket. One end of the first chain 315 is hinged to one swinging end of the swing frame 311, and the other end is fixedly connected to the first sprocket. The first motor 312 can sequentially drive the swing frame 311 to swing around its rotation point relative to the frame 320 via the first reducer 313, the first drive shaft 314, the first sprocket, and the first chain 315 to adapt to different input ends of the pallet stacking device 400. The first motor 312 is electrically connected to the control device.

[0037] In this embodiment, the gear chain lifting method provides a smoother lifting process and better continuity of movement. In this embodiment, the first motor 312 is a servo motor, which facilitates control of the rotation angle. In this embodiment, both ends of the first drive shaft 314 are equipped with first sprockets; this design ensures the balance of both sides of the swing frame 311 and increases the overall structural stability. In this embodiment, the swing frame 311 can be moved forward or backward simply by rotating the first motor 312, thus adapting to the input ends of the connecting plate mechanism 410 at different positions.

[0038] In the above embodiments, due to the use of a gear chain design, sawdust and dust can easily get stuck in the chain holes during actual use. This causes a gap in the engagement between the first sprocket and the first chain 315, which in turn makes it easy for the first motor 312 to drive the swing frame 311 to swing at an inaccurate angle when the first motor 312 drives the swing frame 311 through the engagement of the first sprocket and the first chain 315. This affects the coordination between the clamping assembly and the pallet stacking device 400. Therefore, this solution requires frequent cleaning of the dust or sawdust deposited on the first sprocket and the first chain 315 to ensure the normal operation of the above equipment. Of course, in the above embodiments, the swing frame 311 can also be driven to swing by a motor-driven cam linkage structure, which will not be described in detail here.

[0039] See Figure 3 and Figure 4In the above embodiment, in order to smoothly convey the plate, the clamping assembly includes a driving roller 316 and a driven roller 317 arranged parallel to each other. The driving roller 316 and the driven roller 317 are rotatably mounted on the swing frame 311. The same end of the driving roller 316 and the driven roller 317 are connected by gear meshing. The other end of the driving roller 316 is connected to the output end of the transmission mechanism 340. The swing frame 311 is provided with a plurality of adjusting brackets 318. All the adjusting brackets 318 are arranged in upper and lower layers. All the adjusting brackets 318 are rotatably mounted with rollers 319. A belt 31a is wound between the rollers 319 and the driven roller 317 on the upper layer of the adjusting bracket 318, and a belt 31a is also wound between the rollers 319 and the driving roller 316 on the lower layer of the adjusting bracket 318.

[0040] In this embodiment, the two ends of the drive roller 316 are mounted on the frame 320 via bearings, and the rotation center of the swing frame 311 is coaxially arranged with the drive roller 316. This simplifies the structure. Therefore, in actual use, one end of the swing frame 311 is mounted on both ends of the drive roller 316 via bearings, further simplifying the structure. It should be noted that in this application, the drive roller 316 is also connected to the output end of the drive motor 341 via a transmission chain 342, which simplifies the structure and reduces the number of drive devices.

[0041] In the above embodiments, to facilitate adjustment of the tension of the belt 31a, in an improved embodiment, an adjusting screw is screwed onto the adjusting bracket 318, and a roller 319 is rotatably mounted on the outward end of the adjusting screw, with the rotation center of the roller 319 perpendicular to the axial direction of the adjusting screw. A nut is rotatably mounted on the adjusting bracket 318, and the adjusting screw is screwed onto the nut, facilitating adjustment by the operator. In practice, a plug structure is provided on the outward end of the adjusting screw, making it easy to install on the roller 319.

[0042] See you again Figure 1 , Figure 2In one embodiment of this application, to better clamp and feed the plates and ensure stable transport, the plate receiving and stacking device 400 includes a frame 430 and several receiving and feeding mechanisms 440. The input ends of all receiving mechanisms 410 are respectively adapted to the output ends of all receiving and feeding mechanisms 440. All receiving and feeding mechanisms 440 and receiving mechanisms 410 are mounted on the frame 430. The input ends of all receiving and feeding mechanisms 440 can connect with the swinging feeding mechanism 3. The output end of 10 is adapted to receive the board skin output by the swing clamping mechanism 310. Each board receiving mechanism 410 is provided with a corresponding external delivery device 500 below it. The frame 430 is provided with a pressing mechanism 450 above each board receiving mechanism 410. The pressing mechanism 450 can press the board skin received by the board receiving mechanism 410 downward onto the lifting and stacking mechanism 420. The pressing mechanism 450 and the receiving clamping mechanism 440 are both electrically connected to the control device.

[0043] In the above embodiments, the receiving and conveying mechanism 440 can be a conventional double-belt conveying mechanism. Its main purpose is to connect the swing conveying mechanism 310 and the different receiving mechanisms 410 to realize the transfer of the sheet metal. In one embodiment of this application, the receiving and conveying mechanism 440 is designed with three sets, therefore the receiving mechanism 410 is also designed with three sets, and correspondingly, the pressing mechanism 450 and the lifting and stacking mechanism 420 are also provided with three sets, respectively corresponding to the stacking of sheet metal of three different quality specifications: first-class, second-class, and qualified products.

[0044] It should be noted that, in order to simplify the design and reduce the R&D cost, the pressing mechanism 450 and the receiving mechanism 410 in this embodiment can both adopt the technical solution in patent CN111153223A - a plate stacking device. Even the entire receiving and stacking device 400 can adopt the above-mentioned prior art solution, as long as it can realize the functions of conveying, unloading and stacking. This application does not describe the specific structure of the pressing mechanism 450 and the receiving mechanism 410 in detail.

[0045] See Figure 2In one embodiment of this application, in order to effectively adapt to the stacking of sheet metal of different heights, the lifting and stacking mechanism 420 includes a lifting motor 421 mounted on a frame 430, a lifting frame 422 slidably mounted on the frame 430, and a plurality of lifting chains 423 wound around the frame 430. The lower ends of all the lifting chains 423 are connected to the lifting frame 422. The lifting motor 421 can retract the other end of the lifting chain 423. The lifting frame 422 can receive the sheet metal pressed down by the pressing mechanism 450. The lifting motor 421 can place the stacked sheet metal on the lifting frame 422 onto the input end of the external delivery device 500. The external delivery device 500 can transfer the stacked sheet metal on the lifting frame 422 outward. The lifting motor 421 is electrically connected to a control device.

[0046] In the above embodiment, as the receiving mechanism 410 continuously receives new boards and the boards on the lifting frame 422 gradually increase in height under the pressing action of the pressing mechanism 450, the control device controls the lifting motor 421 to rotate in order to lower the lifting frame 422 and the board stack on it by the height of one board by lowering the lifting chain 423. This can adapt to the action of the receiving mechanism 410 and avoid the excessively high board stack from affecting the action of the receiving mechanism 410.

[0047] See Figure 5 In order to enable the stacked sheets of a preset height already piled on the lifting frame 422 to be transported outward and prepared for new stacks of sheets, in one embodiment of this application, each of the outward delivery devices 500 includes a support frame 510, a plurality of multi-segment conveyor belts 520 adapted to the receiving mechanism 410, and two outward delivery transmission chains 530 that are vertically and vertically mounted on the support frame 510. The two outward delivery transmission chains 530 are installed at one output end of all the multi-segment conveyor belts 520, with the innermost one... The external transmission chain 530 is set in the segment gap inside the multi-segment conveyor belt 520. The support frame 510 is equipped with a lifting mechanism 540 for lifting the two external transmission chains 530. The support frame 510 is equipped with a conveyor motor 550 for driving the multi-segment conveyor belt 520. The lifting mechanism 540 is equipped with an external transmission motor 560 for driving the external transmission chain 530. The lifting mechanism 540, the external transmission motor 560 and the conveyor motor 550 are all electrically connected to the control device.

[0048] In this embodiment, when the lifting frame 422 descends to the multi-segment conveyor belt 520, since the multi-segment conveyor belt 520 has a multi-segment structure, and in order to facilitate the transfer of the stacked sheet metal on the lifting frame 422 to the multi-segment conveyor belt 520, the lifting frame 422 is a frame structure in this embodiment. When the lifting frame 422 descends to the conveying plane of the multi-segment conveyor belt 520, the two side frames of the lifting frame 422 in the conveying direction of the multi-segment conveyor belt 520 are exactly located in the gap between different segments inside the multi-segment conveyor belt 520. This allows the stacked sheet metal on the lifting frame 422 to fall exactly onto a certain segment of the multi-segment conveyor belt 520. Then, the conveying capacity of that segment of the multi-segment conveyor belt 520 transports the entire stacked sheet metal outward to another segment. In this way, the lifting frame 422 can be reset to wait for the next batch of stacked sheet metal. It should be noted that after the sheet stack on the lifting frame 422 is transferred to the multi-segment conveyor belt 520, the multi-segment conveyor belt 520 transfers the sheet stack to the area where the two external transmission chains 530 are located. At this time, the lifting mechanism 540 rises, lifts the sheet stack on the output end of the multi-segment conveyor belt 520 and separates it from the multi-segment conveyor belt 520, so that the sheet stack can be externally transported.

[0049] It should be further explained that, since there are multiple outward conveying devices 500 in this application, and adjacent outward conveying devices 500 are directly adjacent, even if the multi-segment conveyor belt 520 directly transfers its corresponding sheet metal stacks outward, due to space constraints, the external handling equipment does not have enough space to operate. In order to simplify the structure and improve the operating space, the two outward conveying transmission chains 530 at the ends of two adjacent multi-segment conveyor belts 520 are actually interconnected and can be lifted and lowered independently. This operation mainly utilizes the two outward conveying transmission chains 530 at the ends of each multi-segment conveyor belt 520 to form an outward conveying channel. All sheet metal stacks on the multi-segment conveyor belts 520 are ultimately conveyed outward through this channel, which facilitates the transfer of sheet metal stacks outward by external handling equipment, such as forklifts and overhead cranes.

[0050] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
