Fig. 1 illustrates a sheet stocker 100 provided in the present invention, wherein the sheet stocker 100 is disposed on a sheet production line between a sheet extrusion device and a sheet winding device. The sheet is pulled by the downstream sheet take-up apparatus and passes through the sheet stocker 100, and the sheet stocker 100 is configured to temporarily store a certain sheet and maintain the surface tension of the stored sheet constant when the sheet take-up apparatus changes rolls.
Referring to fig. 3, the sheet storage rack 100 includes a rack body 1, a first fixing roller 21 and a second fixing roller 22 both rotatably disposed at the bottom of the rack body 1, a moving assembly capable of driving a portion of sheets to move up and down, a tension monitoring assembly capable of monitoring surface tension of the sheets, and a controller 5 serving as a control center of the sheet storage rack 100. The frame body 1 is a four-corner steel frame structure and constitutes the skeleton main body of the sheet storage frame 100, the frame body 1 is provided with a feeding roller 11 and a plurality of discharging rollers 12, and the feeding roller 11, the first fixed roller 21, the second fixed roller 22 and each discharging roller 12 can independently rotate and extend along the left and right directions.
The moving assembly comprises a pair of moving rods 31 movably connected to the frame body 1, a first moving roller 32 and a second moving roller 33 both rotatably connected to the pair of moving rods 31, and a moving motor 34 capable of driving the pair of moving rods 31 to move up and down synchronously. The pair of moving bars 31 are arranged on the frame 1 in a left-right opposed manner, and the first moving roller 32 and the second moving roller 33 each extend in the left-right direction and are located inside the pair of moving bars 31. Wherein, the moving motor 34 is a servo motor to precisely control the lifting speed of the moving rod 31.
Referring to fig. 2, the tension monitoring assembly includes a tension cylinder 41 with a cylinder output shaft 43, a tension roller 44 fixedly attached to the cylinder output shaft 43, and a linear displacer 45 with a slide 46. The tension cylinder 41 is fixedly attached to the bottom of the frame 1 and includes a cylinder block 42, and a cylinder output shaft 43 is located on an upper side of the cylinder block 42 and extends in the up-down direction. The cylinder 42 can store a gas under a certain pressure, and the cylinder output shaft 43 can be extended and contracted relative to the cylinder 43 by the gas and an external force.
The pressure roller 44 is located on the upper side of the cylinder output shaft 42 and extends along the left-right direction, and the slide sheet 46 on the linear shifter 45 is fixedly connected with the tension roller 44 and can slide up and down under the driving of the pressure roller 44. The linear displacer 45 is able to identify the real-time position of the slide 46 and send a corresponding signal outwards. In other embodiments, the sliding piece can also be fixedly connected with the cylinder output shaft.
As shown in fig. 4, the sheet stocker 100 further has a human-computer interaction panel 51, and the controller 5 is simultaneously in signal connection with the linear displacement 45, the moving motor 34, the tension cylinder 41, and the human-computer interaction panel 51. The controller 5 is pre-stored with a set position corresponding to the slide 46 and a set pressure corresponding to the tension cylinder 41, and is configured to control the tension cylinder 41 to maintain the internal air pressure at the set pressure and to control the moving motor 34 to rotate at a specific speed. The interactive panel 51 allows the operator to operate the sheet stocker 100 and input the set position stored in the controller 5 to the set pressure.
The working principle of the sheet storage rack 100 is explained as follows: the web is passed in a serpentine manner over and against the feed roll 11, the first moving roll 32, the first fixed roll 21, the tension roll 44, the second fixed roll 22, the second moving roll 33, and the several discharge rolls 12 in sequence. The gas in the tension cylinder 4 is maintained at a set pressure, and the tension roller 44 is maintained in a stationary state by the cooperation of the tension cylinder 4 and the surface tension of the sheet, and at this time, the slider 46 on the linear displacer 45 is located at a set position.
When the downstream sheet winding device stops winding, the controller 5 starts the moving motor 34, and the moving motor drives the pair of moving rods 31 to move upward and make the first moving roller 32 and the second moving roller 33 stretch the sheet, so as to maintain the surface tension in the sheet storage rack 100. In this process, if the moving motor 34 rotates too fast, the surface tension of the sheet will rise and the sheet will press down the tension roller 44. The slider 46 on the linear shifter 45 moves to below the set position, and the controller 5, upon receiving a signal from the linear shifter 45, reduces the rotational speed of the moving motor 34 until the slider returns to the set position, thereby maintaining the surface tension of the sheet constant. Similarly, if the rotation speed of the moving motor 34 is too slow, the surface tension of the sheet will decrease, and the tension cylinder 4 will lift the tension roller 44 upward. The slider 46 on the linear shifter 45 moves above the set position, and the controller 5 increases the rotation speed of the moving motor 34 until the slider returns to the set position after receiving the signal from the linear shifter 45, thereby maintaining the surface tension of the sheet material constant.
When the downstream sheet take-up device is rewound, the sheet speed at the discharge roller 12 is higher than the sheet speed at the feed roller 11. To keep the surface tension of the sheet constant, the controller 5 moves the pair of moving bars 31 downward by the moving motor 34, releasing the stored sheet. The method for adjusting the rotation speed of the moving motor 34 is the same as above, and is not repeated herein.
The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the foregoing description only for the purpose of illustrating the principles of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims, specification, and equivalents thereof.
