Description

Technical Field

[0001] This application relates to the technical field of roller taking equipment, and in particular to a roller taking device. Background Technology

[0002] During the production and processing of decorative paper, the decorative paper needs to be wound onto the outer surface of a roller. The roller has through holes, and the center line of the through holes is the same as the center line of the roller.

[0003] Properly placing rollers to fully utilize space while ensuring efficient roller retrieval is crucial for improving the smoothness and efficiency of the entire decorative paper production process. In the past, to accommodate more rollers within a limited space, they were typically arranged closely vertically, with adjacent rollers kept very close together. When a roller needed to be retrieved, operators often had to manually move it out of the placement area. Because different rollers have different radii, retrieving a roller located in the middle of the placement area required first moving aside the rollers on the periphery, a cumbersome and inefficient process that significantly impacted the decorative paper production schedule and needs improvement. Utility Model Content

[0004] The purpose of this application is to provide a roller picking device for conveniently picking up rollers in the middle of the placement area.

[0005] The roller-picking device provided in this application adopts the following technical solution: it includes a base and a controller. The base is slidably connected to a gantry frame. The base is connected to a first drive assembly, which drives the gantry frame to slide along the X-axis. The gantry frame is slidably connected to a roller-picking frame. The gantry frame is connected to a second drive assembly, which drives the roller-picking frame to slide along the Y-axis. The roller-picking frame is slidably connected to a roller-picking plate. A first electromagnet is connected to one side of the roller-picking plate. The first electromagnet is electrically connected to the controller. The roller-picking frame is connected to a lifting assembly, which drives the roller-picking plate to rise and fall.

[0006] By adopting the above technical solution, the first drive component drives the gantry to slide along the X-axis, and the second drive component drives the roller-picking frame to slide along the Y-axis. The position of the roller-picking frame is adjusted so that the roller-picking plate is above the roller to be picked up. The lifting component drives the roller-picking plate to descend until the first electromagnet abuts against the roller. The controller controls the first electromagnet to be energized to generate magnetic force. The first electromagnet attracts the roller. The lifting component drives the roller-picking plate to rise, and the attracted roller also rises with the roller-picking plate. The first drive component drives the gantry to slide along the X-axis, and the second drive component drives the roller-picking frame to slide along the Y-axis, so that the attracted roller is moved out of the placement area. This avoids moving the outer rollers one by one, thus making it convenient and quick to pick up rollers at different positions in the placement area.

[0007] Optionally, the roller plate is connected to a first positioning post, and there are several first electromagnets, all of which surround the first positioning post. The first positioning post is used to cooperate with the through hole of the roller.

[0008] By adopting the above technical solution, during the descent of the roller plate, the first positioning post is inserted into the through hole of the roller. The first positioning post cooperates with the inner wall of the through hole of the roller, which enables the first electromagnet to accurately position the roller. Multiple first electromagnets can more stably attract the roller, which facilitates the roller removal operation.

[0009] Optionally, a first guide portion is provided at the end of the first positioning post away from the roller plate, and the radius of the first guide portion gradually increases towards the first positioning post.

[0010] By adopting the above technical solution, the first guide part guides the first positioning post to be inserted into the through hole of the roller, so that the first positioning post can be inserted into the through hole of the roller more smoothly.

[0011] Optionally, the lifting assembly includes a sprocket rotatably connected to the picking roller frame, a chain fixedly connected to the sprocket, and a drive structure connected to the picking frame. The drive structure is used to drive the sprocket to rotate. One end of the chain away from the sprocket is fixedly connected to the picking roller plate. The picking roller frame is connected to a guide plate. The guide plate is provided with a first guide hole, which is used to slide and cooperate with the chain.

[0012] By adopting the above technical solution, the drive structure drives the sprocket to rotate, causing the chain to wind onto or unwind from the sprocket, thereby achieving the lifting and lowering of the roller plate. The sliding engagement between the chain and the first guide hole guides and limits the lifting and lowering of the chain, thus improving the stability of the chain lifting and lowering, and consequently improving the stability of the roller plate lifting and lowering.

[0013] Optionally, the driving structure includes a rotating rod rotatably connected to the roller frame and a first driving member for driving the rotating rod to rotate. The first driving member is connected to the roller frame. The sprocket is fixedly connected to the rotating rod. The rotating rod is fixedly connected to two limiting plates, and the sprocket is located between the two limiting plates.

[0014] By adopting the above technical solution, the first driving component drives the rotating rod to rotate, the sprocket rotates around the axis of the rotating rod, and the two limiting plates play a limiting role in the winding of the chain, thereby improving the stability of the chain being wound.

[0015] Optionally, the rotating rod is fixedly connected to two take-up reels, the two limiting plates are located between the two take-up reels, each take-up reel is fixedly connected to a pull rope, the end of the pull rope away from the take-up reel is fixedly connected to the take-up roller plate, and the guide plate is provided with a second guide hole corresponding to the pull rope, the second guide hole is used to slide and cooperate with the pull rope.

[0016] By adopting the above technical solution, the pull rope can assist the chain in driving the lifting and lowering of the roller plate, making the lifting and lowering of the roller plate more stable. The sliding cooperation between the pull rope and the second guide hole plays a guiding and limiting role in the lifting and lowering of the pull rope, thereby improving the stability of the pull rope sliding.

[0017] Optionally, the roller picker frame is slidably connected to a support plate, and the roller picker frame is connected to a second driving member. The second driving member is used to drive the support plate to slide, and the support plate is used to support the roller.

[0018] By adopting the above technical solution, when the roller is lifted by the first electromagnet and the roller-picking plate, the second driving component drives the support plate to slide, so that the support plate is located below the lifted roller. The support plate plays a supporting role for the roller, which can further improve the stability of the roller during the roller picking process and prevent the roller from shaking or falling.

[0019] Optionally, the support plate is connected to a plurality of second electromagnets, which are electrically connected to the controller.

[0020] By adopting the above technical solution, when the support plate supports the roller, the suspended roller comes into contact with the second electromagnet. The controller controls the second electromagnet to be energized to generate magnetic force. The second electromagnet attracts the roller, which enhances the fixing effect on the roller and prevents the roller from falling during the roller picking and moving process, thereby improving the stability and reliability of the roller picking device.

[0021] Optionally, it also includes a flattening frame, which is rotatably connected to a rotating plate. The flattening frame is connected to a third driving member, which drives the rotating plate to rotate. The rotating plate is connected to a second positioning post and several third electromagnets, and the third electromagnets are electrically connected to the controller.

[0022] By adopting the above technical solution, the suspended roller is moved above the rotating plate by the first and second driving components, with the through hole of the roller corresponding to the second positioning post. The first driving component drives the rotating rod to rotate, causing the suspended roller to engage with the second positioning post and abut against the third electromagnet. The controller de-energizes the first electromagnet and energizes the third electromagnet, which then attracts the roller. The first driving component drives the rotating rod to rotate in the opposite direction, raising the roller-picking plate. The third driving component drives the rotating plate to rotate, and the roller on the third electromagnet rotates with the rotation of the rotating plate, flattening the roller for subsequent handling.

[0023] Optionally, it also includes a first connecting seat and a second connecting seat, wherein the flattening frame slides on the first connecting seat, the second connecting seat is slidably connected to a support plate, the support plate is connected to a third positioning post and a plurality of fourth electromagnets, the fourth electromagnets are electrically connected to the controller, the first connecting seat is connected to a third driving assembly, the third driving assembly is used to drive the flattening frame to slide toward or away from the support plate, and the second connecting seat is connected to a fourth driving assembly, the fourth driving assembly is used to drive the support plate to slide toward or away from the flattening frame.

[0024] By adopting the above technical solution, after the rotating plate flattens the roller, the third drive component drives the flattening frame to slide towards the support plate, the fourth drive component drives the support plate to slide towards the flattening frame, the third positioning pin is inserted into the through hole of the roller and one side of the roller abuts against the fourth electromagnet, the controller controls the fourth electromagnet to be energized and attract the roller, thereby improving the stability of the roller being flattened and facilitating the subsequent handling of the roller.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The first drive assembly drives the gantry to slide along the X-axis, and the second drive assembly drives the roller-picking frame to slide along the Y-axis. The position of the roller-picking frame is adjusted so that the roller-picking plate is above the roller to be picked up. The lifting assembly drives the roller-picking plate to descend until the first electromagnet abuts against the roller. The controller controls the first electromagnet to be energized to generate magnetic force. The first electromagnet attracts the roller. The lifting assembly drives the roller-picking plate to rise, and the attracted roller also rises with the roller-picking plate. The first drive assembly drives the gantry to slide along the X-axis, and the second drive assembly drives the roller-picking frame to slide along the Y-axis, so that the attracted roller is moved out of the placement area. This avoids moving the outer rollers one by one, thus making it convenient and quick to pick up rollers at different positions in the placement area.

[0026] 2. The pull rope can assist the chain in driving the lifting and lowering of the roller plate, making the lifting and lowering of the roller plate more stable. The sliding cooperation between the pull rope and the second guide hole plays a guiding and limiting role in the lifting and lowering of the pull rope, thereby improving the stability of the pull rope sliding.
