Description

Technical Field

[0001] This utility model relates to the technical field of supporting equipment for sheet metal processing, and in particular to a continuous sheet metal stacker. Background Technology

[0002] Engineered wood products (AWD) are boards or molded products made from wood or other non-wood plant materials. These materials are mechanically processed into various unit materials and then bonded together with or without adhesives and other additives. The process includes cutting, drying, gluing, and molding. After molding, AWD undergoes quality inspection and cooling before being transported to a stacker crane for stacking, enabling batch transfer and improving efficiency. Currently used stacker cranes typically have two stacking stations that work alternately and in coordination to achieve continuous stacking of AWD, adapting to the continuous production line requirements.

[0003] During the alternating operation of two stacking stations, when the current stacking station reaches its stacking limit and product transfer is required, it needs to be switched from stacking to conveying mode to transport the engineered wood panels to the next stacking station. When the next stacking station reaches its stacking limit and product transfer is required, the control switches the previous stacking station back from conveying to stacking mode, repeating this cyclical control to achieve uninterrupted stacking of engineered wood panels. Therefore, based on the functional switching of the previous stacking station, it must have a lifting conveying mechanism. During stacking, this mechanism needs to lift to allow the engineered wood panels to descend and complete the stacking; during conveying, the mechanism needs to return to a horizontal position to transport the engineered wood panels to the next stacking station. Currently, this mechanism is a single, movable installation, which is large in size and weight, causing a certain lag in lifting, lowering, and returning. When using the same production line to produce engineered wood panels of different thicknesses, especially thin panels, the production and conveying speeds are relatively fast. The lifting and returning speeds of the conveying mechanism are clearly not up to par with the stacking requirements of thin panels, which can easily cause collisions with the thin panels, thus affecting the smooth stacking process and causing unnecessary damage to the thin panels. Therefore, it is necessary to improve the stacking machine currently in use to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a continuous plate stacker that can perform graded control according to the thickness of the plate, has a fast response speed, and can fully meet the requirements of thin plate stacking.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a continuous plate stacker, including a frame, on which a front stacking station and a rear stacking station are formed along the traveling direction of the plate. At the front stacking station on the frame, a plate feeding device and a plate discharging device are sequentially arranged along the traveling direction of the plate, and their adjacent ends are rotatably connected. The discharge end of the plate discharging device is rotatably connected to the frame. The feeding side of the plate feeding device and the plate discharging device are respectively connected to the frame with a lifting mechanism. A stacking guide device is installed on the frame corresponding to the rear stacking station.

[0006] As a preferred technical solution, the plate feeding device includes a feeding receiving plate for receiving plates. The discharge side of the feeding receiving plate is rotatably connected to the end of the plate feeding device. A plate anti-friction roller is arranged and installed through the feeding receiving plate, and the top of the plate anti-friction roller protrudes from the surface of the feeding receiving plate.

[0007] As a preferred technical solution, the receiving plate is evenly distributed in sections on the frame.

[0008] As a preferred technical solution, the sheet material feeding device includes a belt feeding mechanism.

[0009] As a preferred technical solution, the stacking guide device includes a stacking guide inclined frame that is gradually lowered along the direction of plate travel, and the stacking guide inclined frame is fixedly installed on the frame.

[0010] As a preferred technical solution, the discharge end of the stacking guide inclined frame is connected to a stacking limiting flat frame, which is fixedly installed on the frame.

[0011] As a preferred technical solution, the lifting mechanism of the device includes a lifting power component fixedly installed on the top of the frame, the lifting power component is drivenly connected to a lifting traction component, and the bottom end of the lifting traction component is rotatably assembled with the corresponding plate feeding device or plate discharging device.

[0012] As a preferred technical solution, a plate feeding shaft is rotatably installed on the frame at the feeding end of the plate feeding device and the stacking guide device, respectively. Plate feeding rollers are correspondingly arranged on each plate feeding shaft. A plate floating pressure roller is correspondingly arranged on the frame above the plate feeding rollers. The plate feeding shaft is driven by a plate feeding motor, and the plate feeding motor is fixed on the frame.

[0013] As an improvement to the above technical solution, a plate feeding guide plate is arranged and installed on the frame in front of the plate feeding roller, and the discharge end of the plate feeding guide plate is set to correspond to the gap between the plate feeding roller and the plate floating pressure roller.

[0014] Due to the adoption of the above technical solution, the continuous plate stacker includes a frame. A front stacking station and a rear stacking station are formed on the frame along the plate's travel direction. A plate feeding device and a plate discharging device are sequentially arranged on the frame at the front stacking station along the plate's travel direction, with their adjacent ends rotatably connected. The discharge end of the plate discharging device is rotatably connected to the frame. Lifting mechanisms are respectively connected between the feeding side of the plate feeding device and the plate discharging device and the frame. A stacking guide device is installed on the frame corresponding to the rear stacking station. This utility model has the following beneficial effects: the plate feeding device and the plate discharging device... The ends can be lifted using corresponding lifting mechanisms. When stacking operations are performed at the front stacking station and the thickness of the processed sheet is small, only the sheet is lifted and fed into the device. When the thickness of the processed sheet is large, both the sheet feeding device and the sheet delivery device need to be lifted. This achieves graded control based on sheet thickness, reduces the burden on the lifting mechanism, and makes it respond faster. This allows for the smooth and safe stacking of thin sheets conveyed at high speed. With the cooperation of the lifting mechanism, the front and rear stacking stations can work together and be used alternately to complete the continuous stacking of sheets, maximizing the efficient production of sheets of various thicknesses on the sheet processing line.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0026] like Figures 1 to 8 As shown, a continuous sheet metal stacker is used in conjunction with a sheet metal production line and is located at the output end of the formed sheet metal. It receives processed sheet metal and continuously stacks it to facilitate the batch transfer and storage of the formed sheet metal. Specifically, it includes a frame 1, which serves as the supporting structure for the entire stacker and is used to install related structures for sheet metal stacking. The frame 1 has a front stacking station A and a rear stacking station B along the sheet metal's travel direction. During operation, by controlling the actions of related structures, the front stacking station A and the rear stacking station B are used alternately, facilitating the transfer of batches of stacked sheet metal and ensuring a continuous output of stacked formed sheet metal. The frame 1 is a frame structure; it can be a one-piece structure or a separate structure corresponding to the front stacking station A and the rear stacking station B respectively. When the frame 1 is configured as two separate parts, the ends are joined together. To improve the stability of the frame 1 during use, it can be fixed to the ground with bolts.

[0027] At the front stacking station A and the rear stacking station B, lifting forks are respectively provided for receiving and supporting the stacking of sheet metal. After the sheet metal is stacked on the lifting forks, it can be transferred in one go using a forklift, and the lifting forks can be raised and reset to await the next stacking of sheet metal. This part is well known to those skilled in the art and will not be described in detail here.

[0028] The frame 1 is equipped with a sheet material feeding device and a sheet material dispensing device sequentially along the direction of sheet material travel at the front stacking station A, with their adjacent ends rotatably connected. The discharge end of the sheet material dispensing device is rotatably connected to the frame 1. A lifting mechanism is correspondingly connected between the feeding side of the sheet material feeding device and the frame 1. When the thickness of the sheet material varies, its processing efficiency and conveying speed also differ. When the sheet material is thin, the processing and conveying speeds are relatively fast. This requires the front stacking station A to have a fast switching speed between conveying and stacking functions to avoid collisions between related structures and thin sheets, which could damage the sheet material and affect the smooth implementation of stacking. The sheet material feeding device and the sheet material dispensing device are sequentially arranged on the frame 1, and each is equipped with a lifting mechanism to achieve the above effect.

[0029] Specifically, when stacking sheet metal at the front stacking station A, if the sheet metal is thin, the feeding side of the sheet metal feeding device connected to it is lifted to a certain height only by the lifting mechanism of the device. Since the sheet metal is thin, after being fed into the frame 1, its end will naturally droop within a short distance and automatically rest on the lifting fork at the station. As the conveying continues, the sheet metal is pushed forward until it completely falls onto the lifting fork, completing the stacking. However, when the sheet metal is relatively thick, after being fed into the frame 1, its end needs to travel a relatively long distance to droop naturally. In order to avoid the relevant structures on the frame 1 from obstructing the movement of its end, in addition to the feeding side of the sheet metal feeding device, the feeding side of the sheet metal discharging device also needs to be lifted to avoid the movement of the sheet metal end. Therefore, this embodiment can adjust the timing of the lifting of the plate feeding device and the plate delivery device according to the thickness of the plate, thereby improving the response speed and better meeting the needs of stacking thin plates. This eliminates the response lag caused by the need to lift the entire mechanism on the frame 1 in the prior art. When stacking plates using the rear stacking station B, both the plate feeding device and the plate delivery device are in a horizontal state, serving only to transfer plates to the rear stacking station B.

[0030] The sheet material feeding device includes a feeding receiving plate 2 for receiving the sheet material. The discharge side of the feeding receiving plate 2 is rotatably connected to the end of the sheet material feeding device. Anti-friction rollers 3 are installed through the feeding receiving plate 2, with the top of the anti-friction rollers 3 protruding from the surface of the feeding receiving plate 2. Under the action of the anti-friction rollers 3, the sheet material forms rolling contact with the feeding receiving plate 2, which helps reduce the friction between them and ensures rapid and wear-free conveying of the sheet material. The feeding receiving plates 2 are evenly distributed in sections on the frame 1 for easy installation.

[0031] The sheet material feeding device in this embodiment includes a belt feeding mechanism 4, which is equipped with a belt frame, pulleys, a drive shaft, a belt motor, and other components. The feeding receiving plate 2 is rotatably connected to the belt frame, and the tail end of the belt frame is rotatably connected to the frame 1. With the cooperation of the belt frame and the feeding receiving plate 2, the conveying structure of the sheet material at the front stacking station A is divided into two parts, and each part can be lifted independently to meet the stacking needs of sheet materials of different thicknesses at this station. Alternatively, anti-friction rollers 3 can be installed on both sides of the belt frame to provide conveying support for the sheet material and prevent wear.

[0032] The lifting mechanism of the device includes a lifting power component 5 fixedly installed at the top of the frame 1. The lifting power component 5 is drivenly connected to a lifting traction component 6, and the bottom end of the lifting traction component 6 is rotatably assembled with the corresponding plate feeding device or plate discharging device. In use, under the power of the lifting power component 5, the corresponding feeding receiving plate 2 or the belt frame is pulled and lifted by the lifting traction component 6. The lifting power component 5 and the lifting traction component 6 can be configured as a hydraulic pump and hydraulic cylinder, a motor and wire rope winding, or a motor and crank / connecting rod, etc.

[0033] A stacking guide device is installed on the frame 1 corresponding to the rear stacking station B, allowing the sheet metal to tilt downwards and gradually fall onto the lifting fork at that station after entering the rear stacking station B. In this embodiment, the stacking guide device includes a stacking guide inclined frame 7 that gradually decreases in the direction of sheet metal travel. The stacking guide inclined frame 7 is fixedly installed on the frame 1. The tilting of the stacking guide inclined frame 7 creates downward pressure on its end as the sheet metal travels, allowing it to fall smoothly onto the lifting fork. A stacking limiting flat frame 8 is connected to the discharge end of the stacking guide inclined frame 7. The stacking limiting flat frame 8 is fixedly installed on the frame 1. The stacking guide inclined frame 7 and the stacking limiting flat frame 8 are connected at the middle of the rear stacking station B, thereby reducing the length of the stacking guide inclined frame 7 and facilitating its arrangement and installation.

[0034] On the frame 1, at the feeding ends of the sheet material feeding device and the stacking guide device, sheet material feeding shafts 9 are rotatably mounted. Each sheet material feeding shaft 9 is equipped with a corresponding sheet material feeding roller 10. Above each sheet material feeding roller 10, a corresponding floating pressure roller 11 is provided on the frame 1 for cooperation. A sheet material feeding motor 12 is driven by the sheet material feeding shaft 9 and is fixed to the frame 1. The sheet material feeding motor 12 drives the sheet material feeding shafts 9 and the sheet material feeding rollers 10 to rotate, thus propelling the fed sheet material. The floating pressure roller 11 cooperates with the sheet material feeding rollers 10 to clamp the sheet material, ensuring successful forward feeding and conveying. The frame 1 is equipped with a pressure roller force applicator 13 corresponding to each of the floating pressure rollers 11 of the plate, so as to adjust the height of the floating pressure roller 11 of the plate according to the thickness of the plate, thereby adjusting the gap between it and the plate feeding roller 10, so as to ensure that both can form sufficient clamping force on the plate.

[0035] A sheet material feeding guide plate 14 is arranged and installed on the frame 1 in front of the sheet material feeding roller 10. The discharge end of the sheet material feeding guide plate 14 is set to correspond to the gap between the sheet material feeding roller 10 and the sheet material floating pressure roller 11, so as to realize the smooth feeding of the sheet material from the production line to the front stacking station A and from the front stacking station A to the rear stacking station B.

[0036] In this embodiment, the belt conveyor 4, the lifting power component 5, the plate feeding motor 12, and the pressure roller force applicator 13 are all connected to the controller on the plate production line. Under the control of the controller, the automatic switching between the front stacking station A and the rear stacking station B can be achieved, as well as the timely lifting and return of the feeding receiving plate 2 and / or the belt frame. In conjunction with the sensor on the production line used to detect the plate thickness, the lifting and return of the plate feeding device and the plate feeding device described in this embodiment can also be adaptively adjusted, making the stacker crane more flexible and convenient to use.

[0037] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
