DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Please also see Figures 1 to 5 , are respectively a schematic diagram of the structure of the servo flat-plate reel machine provided by the present invention, a partial enlarged diagram of the reel device and the circulation device, and a schematic diagram showing the working principles of the reel device and the circulation device.

[0019] The servo flat roll machine comprises a roll device 1 and a circulation device 2. The roll device 1 comprises a feeding assembly 11, a forming assembly 12, a discharging assembly 13, a first servo mechanism 14, and a second servo mechanism 15. The circulation device 2 comprises a feed rod assembly 21, a push rod assembly 22, a discharging rod assembly 23, a third servo mechanism 24, and a fourth servo mechanism 25.

[0020] The main body of the forming assembly 12 is a belt mechanism 121, the belt surface of the belt mechanism 121 is horizontal, the width is greater than 1m, and the length is about 0.5m. Above the belt mechanism 121, there is a flat plate 122 installed on the frame through an adjustment mechanism. The distance between the two can be adjusted to adapt to different roll processing conditions. The core rod and paper fed between the belt mechanism 121 and the flat plate 122 are driven by the belt surface of the belt mechanism 121 and rubbed against the flat plate 122 to form a roll.

[0021] A set of roller brush mechanisms 123 is also provided below the belt mechanism 121 and in parallel therewith, for cleaning stains on the belt surface of the belt mechanism 121 to avoid affecting the processing of the reel.

[0022] The feeding assembly 11 is arranged at the far side of the forming assembly 12 shown in the figure, and includes a feeding shaft 111 and a feeding mechanism 112 arranged on the feeding shaft 111. The feeding mechanism 112 includes a groove and a guide plate arranged on one side of the groove. When the core rod falls into the groove, the feeding mechanism 112 is swung along the feeding shaft 111 toward the forming assembly 12, so that the core rod can slide out of the groove, roll along the guide plate to the belt mechanism 121, and be rolled between the flat plates 122 along with the belt mechanism 121.

[0023] The discharging assembly 13 is arranged at the proximal position of the forming assembly 12 as shown in the figure, and includes a discharging shaft 131 and a discharging mechanism 132 arranged on the discharging shaft 131. The discharging mechanism 132 includes a set of cross bars and a guide plate arranged on one side of the cross bars, and the cross bars and the guide plates are both fixed on the frame. When the core bar is released from between the belt mechanism 121 and the flat plate 122, it will fall onto the cross bars along with the guide plates.

[0024] The discharge mechanism 132 also includes a clamping plate, which is arranged on the discharge shaft 131. When the core rod falls on the crossbar, the clamping plate swings along the discharge shaft 131 to form an assembly 12, thereby clamping the core rod. After the core rod is pulled out, the reel on the surface of the core rod remains in the clamped state and remains in place. The clamping plate swings again to release the reel, causing it to fall in the gap between the crossbars.

[0025] The first servo mechanism 14 includes a servo motor, which is transmission-connected to the feed shaft 111 and the discharge shaft 131 to drive the two to operate synchronously.

[0026] Specifically, a swing arm is provided on the feed shaft 111, the end of which is used to install the groove and the guide plate, and the middle part is used to set the tension spring and the guide wheel. The tension spring pulls the guide wheel to abut against a concave wheel driven by the first servo mechanism 14. When the guide wheel is in the flat position of the concave wheel, the feed mechanism 112 does not move, waiting for the core rod to fall into the groove; when the guide wheel is in the concave position of the concave wheel, the feed mechanism 112 swings toward the forming assembly 12 once, so that the core rod is rolled between the flat plates 122.

[0027] A swing arm is provided on the discharge shaft 131, one end of which is used as a clamping plate, and the other end is used to set a tension spring and a guide wheel. The tension spring pulls the guide wheel to abut against a concave wheel driven by the first servo mechanism 14. When the guide wheel is in the flat position of the concave wheel, the discharge mechanism 132 maintains a clamping state; when the guide wheel is in the flat position of the concave wheel, the core rod is withdrawn, and the reel is kept in the original position; when the guide wheel is in the concave position of the concave wheel, the discharge mechanism 132 swings once in the direction away from the forming component 12, loosens the reel and falls naturally, and the processing of a reel is completed.

[0028] The first servo mechanism 14 is connected to the driving shafts of the two cams and the driving shaft of the roller brush mechanism 123 by a gear chain mechanism. The second servo mechanism 15 includes a servo motor and is connected to the driving shaft of the belt mechanism 121 by a gear chain mechanism.

[0029] By controlling the first servo mechanism 14, the start-up frequency of the feeding mechanism 112 and the discharging mechanism 132 can be controlled. By controlling the second servo mechanism 15, the speed of forming the roll on the core rod can be controlled, thereby conveniently achieving the precise coordination of the two processing actions.

[0030] The feed rod assembly 21 is a single chain mechanism, with the length direction being the left-right direction and the width direction being the up-down direction, and the left end extending into the crossbar position close to the discharge mechanism 132. Two hooks are installed on the outer side of the chain of the feed rod assembly 21 as stoppers. As the chain rotates, the hooks can hook the end of the core rod on the crossbar, thereby pulling out the core rod while being clamped by the discharge mechanism 132. A circle of protrusions is provided at the right end of the core rod to facilitate hooking.

[0031] On the near side of the feed rod assembly 21, there are two transfer mechanisms 211 installed on the frame. The transfer mechanism 211 includes an electromagnet, whose movable end faces the upper chain of the feed rod assembly 21, and a V-shaped baffle is provided at the end as a stopper. When the electromagnet is released, the baffle extends, and the V-shaped position clamps the side of the core rod. At the same time, the impact force generated at the moment of the electromagnet release is used to make the core rod slip off the chain of the feed rod assembly 21 and fall onto the push rod assembly 22.

[0032] Of course, a corresponding sensing mechanism is provided at the transfer mechanism 211, which releases the electromagnet when it senses that the core rod is in place, and then retracts the electromagnet to its original position.

[0033] The structure of the rod assembly 23 is similar to that of the rod assembly 21, and the left end thereof extends into a position close to the groove of the feed mechanism 112. Two push plates are installed on the outer side of the chain of the rod assembly 23 as stoppers. In addition, baffles are provided on both sides of the upper chain of the rod assembly 23, and guide plates bent toward the rod assembly 22 are provided above the two baffles. As the chain rotates, the core rod transported from the rod assembly 22 falls onto the chain between the baffles under the action of the guide plates, and then moves into the groove of the feed mechanism 112 under the push of the push plates.

[0034] The push rod assembly 22 is a double chain mechanism, with two sets of chains arranged in parallel, and two hooks are installed at the same position on the outside of the chain as stoppers. The push rod assembly 22 is tilted in the conveying direction, with its head end lower than the upper chain of the feed rod assembly 21, and its tail end higher than the upper chain of the output rod assembly 23. As the chain of the push rod assembly 22 rotates, the hook can convey the core rod thrown from the chain of the feed rod assembly 21 to the direction of the output rod assembly 23, and throw it from the tail end, and fall onto the chain between the baffles under the action of the guide plate of the output rod assembly 23.

[0035] The third servo mechanism 24 includes a servo motor, which is connected to a main shaft through a gear chain mechanism. The main shaft is connected to the drive shafts of the output rod assembly 23 and the input rod assembly 21 through a gear chain mechanism or a gear mechanism. The fourth servo mechanism 25 includes a servo motor, and the drive shaft of the push rod assembly 22 is connected to the drive shaft through a gear chain mechanism.

[0036] The winding method of the servo flat-plate winding machine includes: Step 1: A core rod is preset in the groove of the feeding mechanism 112, and the first servo mechanism 14 operates continuously to drive the feeding mechanism 112 to swing regularly. Each time it swings, a core rod is poured out of the groove and slides between the belt mechanism 121 and the plate 122.

[0037] A paper feeding assembly is also provided above the feeding assembly 11 , and a roll of paper is fed into between the belt mechanism 121 and the flat plate 122 while the core rod is poured out.

[0038] Step 2: The second servo mechanism 15 continues to operate, driving the belt mechanism 121 to rotate, driving the core rod and the paper to move toward the discharge assembly 13. During the movement, the paper and the core rod are entangled together, forming a roll on the surface of the core rod. Finally, the core rod and the roll on the core rod surface roll out from between the belt mechanism 121 and the flat plate 122 and onto the discharge mechanism 132.

[0039] Step 3: The length of the roll on the surface of the core rod is smaller than that of the core rod. When it rolls out and falls onto the discharge mechanism 132, both ends of the core rod are placed on the cross bars of the discharge mechanism 132, and the roll on the surface of the core rod is suspended between the cross bars and clamped by the clamping plates of the discharge mechanism 132.

[0040] The first servo mechanism 14 operates continuously, driving the discharging mechanism 132 to swing periodically. During the interval of swinging, the next core rod and reel will roll out from between the belt mechanism 121 and the flat plate 122 and fall onto the previous core rod and reel. At the same time, the feed rod assembly 21 will pull the previous core rod out of the reel, leaving only the reel to be clamped by the clamping plate of the discharging mechanism 132.

[0041] Each time the reel is swung, the remaining reel is released by the clamping plate of the discharging mechanism 132, so that it falls into the receiving box. At the same time, the core rod and reel originally on the top fall onto the cross bar of the discharging mechanism 132, and are clamped by the clamping plate again when the clamping plate of the discharging mechanism 132 returns.

[0042] Step 4: The third servo mechanism 24 continues to operate, and the claws on the chain of the feed rod assembly 21 hook the core rod clamped by the clamping plate of the discharging mechanism 132, and the roll is pulled out. The core rod further moves rightward with the feed rod assembly 21 continuously.

[0043] A sensor mechanism is provided along the feed rod assembly 21, and when the core rod is in place, the electromagnet of the transfer mechanism 211 is controlled to release. The impact force generated by the electromagnet release moment causes the core rod to slip off the chain of the feed rod assembly 21 and fall onto the push rod assembly 22.

[0044] Step 5: The fourth servo mechanism 25 continues to operate, hooks the core rod through the claws on the chain of the push rod assembly 22, and throws it out from the tail end, and falls on the chain between the baffles under the action of the guide plate of the rod assembly 23. At the same time, the third servo mechanism 24 continues to operate, and pushes the core rod to move left along the baffle through the push plate on the chain of the rod assembly 23, and finally falls into the groove of the feeding mechanism 112. It includes multiple core rods, which cyclically operate at fixed intervals.
