DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0023] Please also refer to Figures 1 to 5 , which are the structural schematic diagrams of the servo flat plate winding drum machine provided by the present application, wherein the partial enlarged view of the winding drum device and the circulating device, and the schematic diagram of the working principle of the winding drum device and the circulating device.

[0024] The servo flat plate winding drum machine comprises a winding drum device 1 and a circulating device 2. The winding drum 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 circulating device 2 comprises a feeding rod assembly 21, a push rod assembly 22, a discharging rod assembly 23, a third servo mechanism 24 and a fourth servo mechanism 25.

[0025] 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, a flat plate 122 is arranged, which is installed on the rack through an adjusting mechanism, and the spacing between the two is adjusted to adapt to different winding drum processing conditions. The core rod and the 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 with the flat plate 122 to form a winding drum.

[0026] A set of roller brush mechanisms 123 are also arranged below and parallel to the belt mechanism 121, which are used to clean the stains on the belt surface of the belt mechanism 121 to avoid affecting the processing of the winding drum.

[0027] The feeding assembly 11 is arranged at the distal position of the forming assembly 12, 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 core rod can be slid out of the groove and rolled onto the belt mechanism 121 along the guide plate by swinging the feeding mechanism 112 along the feeding shaft 111 towards the forming assembly 12, and then wound between the flat plates 122 along with the belt mechanism 121.

[0028] The discharging assembly 13 is arranged at the proximal position of the forming assembly 12, and includes a discharging shaft 131 and a discharging mechanism 132 arranged on the discharging shaft 131. The discharging mechanism 132 includes a plurality of cross bars and guide plates arranged on one side of the cross bars, and the cross bars and the guide plates are fixed on the frame. When the core rod is discharged from between the belt mechanism 121 and the flat plates 122, the core rod will fall onto the cross bars along the guide plates.

[0029] The discharging mechanism 132 further includes a clamping plate arranged on the discharging shaft 131. After the core rod falls onto the cross bars, the clamping plate is swung along the discharging shaft 131 towards the forming assembly 12 to clamp the core rod. After the core rod is pulled out, the winding drum on the surface of the core rod is kept clamped in place. The clamping plate is swung again to release the winding drum, so that the winding drum falls in the gap between the cross bars.

[0030] The first servo mechanism 14 includes a servo motor, which is in driving connection with the feeding shaft 111 and the discharging shaft 131 to drive the feeding shaft 111 and the discharging shaft 131 to operate synchronously.

[0031] Specifically, the feeding shaft 111 is provided with a swing arm, the end of which is used for mounting the groove and the guide plate, and the middle of which is used for arranging a tension spring and a guide wheel. The tension spring abuts against a concave wheel rotating under the drive of the first servo mechanism 14. When the guide wheel is located at the flat position of the concave wheel, the feeding mechanism 112 is stationary, waiting for the core rod to fall into the groove. When the guide wheel is located at the concave position of the concave wheel, the feeding mechanism 112 swings once towards the forming assembly 12, so that the core rod is wound between the flat plates 122.

[0032] The discharging shaft 131 is provided with a swing arm, one end of which serves as a clamping plate, and the other end of which is used for arranging a tension spring and a guide wheel. The tension spring abuts against a concave wheel rotating under the drive of the first servo mechanism 14. When the guide wheel is located at the flat position of the concave wheel, the discharging mechanism 132 keeps clamping. During the process that the guide wheel is located at the flat position of the concave wheel, the core rod is pulled out, and the winding drum is kept in place. When the guide wheel is located at the concave position of the concave wheel, the discharging mechanism 132 swings once away from the forming assembly 12 to release the winding drum, which naturally falls down, thereby completing the processing of one winding drum.

[0033] The first servo mechanism 14 is connected with the driving shafts of the two concave wheels and the driving shaft of the roller brush mechanism 123 by a gear chain mechanism. The second servo mechanism 15 includes a servo motor, which is connected with the driving shaft of the belt mechanism 121 by a gear chain mechanism.

[0034] By controlling the first servo mechanism 14, the starting 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 coil on the core rod can be controlled. Thus, the precise cooperation of the two processing actions can be conveniently realized.

[0035] The feeding rod assembly 21 is a single chain mechanism, the length direction of which is the left-right direction, and the width direction is the up-down direction. The left end of the feeding rod assembly 21 extends to the position close to the cross rod of the discharging mechanism 132. Two hook claws are installed on the outer side of the chain of the feeding rod assembly 21 as limiting members. With the rotation of the chain, the hook claws can hook the end of the core rod located on the cross rod, so that the core rod is pulled out in the state of being clamped by the discharging mechanism 132. The right end of the core rod is provided with a ring of protrusions to facilitate being hooked.

[0036] On the proximal side of the feeding rod assembly 21, there are two transfer mechanisms 211 installed on the frame. The transfer mechanism 211 includes an electromagnet, the active end of which faces the upper side of the chain of the feeding rod assembly 21, and a V-shaped baffle is provided at the end as a limiting member. 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 in the instant of releasing the electromagnet makes the core rod slide off the chain of the feeding rod assembly 21 and fall onto the pushing rod assembly 22.

[0037] Necessarily, corresponding sensing mechanisms are provided at the transfer mechanism 211, which release the electromagnet when the core rod is in place, and then the electromagnet is retracted to the original position.

[0038] The structure of the discharging rod assembly 23 is similar to that of the feeding rod assembly 21, and the left end of the discharging rod assembly 23 extends to the position close to the groove of the feeding mechanism 112. Two push plates are installed on the outer side of the chain of the discharging rod assembly 23 as limiting members. In addition, baffles are provided along the upper chain of the discharging rod assembly 23 on both sides, and a guide plate is provided above the two baffles, which is curved towards the pushing rod assembly 22. With the rotation of the chain, the core rod conveyed from the pushing rod assembly 22 falls onto the chain between the baffles under the action of the guide plate, and then moves to the groove of the feeding mechanism 112 under the pushing of the push plates.

[0039] The pusher assembly 22 is a double chain mechanism, two sets of chains are arranged in parallel, and two hooks are installed as limiters at the same position outside the chains. The pusher assembly 22 is arranged obliquely in the conveying direction, the front end is lower than the upper chain of the feeding assembly 21, and the tail end is higher than the upper chain of the discharging assembly 23. With the rotation of the chain of the pusher assembly 22, the hook can convey the core rod thrown from the chain of the feeding assembly 21 to the discharging assembly 23 direction, and throw it from the tail end, and fall into the chain between the baffle under the action of the guide plate of the discharging assembly 23.

[0040] The third servo mechanism 24 includes a servo motor, which is connected with a main shaft through a gear chain mechanism. The main shaft is connected with the drive shafts of the discharging assembly 23 and the feeding 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 pusher assembly 22 is connected in transmission through a gear chain mechanism.

[0041] The winding method of the servo flat bed winding machine comprises:

[0042] Step 1: A core rod is preset in the groove of the feeding mechanism 112, and the first servo mechanism 14 continuously operates to drive the feeding mechanism 112 to swing regularly. Each swing will pour out a core rod from the groove, and make it slide into the space between the belt mechanism 121 and the flat plate 122.

[0043] A paper feeding assembly is also arranged above the feeding assembly 11, which feeds a winding paper into the space between the belt mechanism 121 and the flat plate 122 at the same time when the core rod is poured out.

[0044] Step 2: The second servo mechanism 15 continuously operates to drive the belt mechanism 121 to rotate, and drive the core rod and the paper to move together to the discharging assembly 13. In the moving process, the paper and the core rod are wound together to form a winding on the surface of the core rod. Finally, the core rod and the winding on the surface of the core rod roll out from the space between the belt mechanism 121 and the flat plate 122 to the discharging mechanism 132.

[0045] Step 3: The length of the winding on the surface of the core rod is less than the length of the core rod, when it rolls out and falls on the discharging mechanism 132, the two ends of the core rod are clamped on the cross bar of the discharging mechanism 132, and the winding on the surface of the core rod is suspended between the cross bars and clamped by the clamping plate of the discharging mechanism 132.

[0046] The first servo mechanism 14 continuously operates to drive the discharging mechanism 132 to swing regularly. In the interval time of the swing, the next core rod and winding will roll out from the space between the belt mechanism 121 and the flat plate 122 and fall on the previous core rod and winding. At the same time, the feeding assembly 21 will pull out the previous core rod from the winding, and only leave the winding clamped by the clamping plate of the discharging mechanism 132.

[0047] Every swing, the remaining reel is released by the clamp plate of the discharge mechanism 132, so that it falls to the receiving box. At the same time, the core rod and the reel originally on the upper fall to the crossbar of the discharge mechanism 132, and are clamped by the clamp plate again when the clamp plate returns.

[0048] Step 4: the third servo mechanism 24 continues to operate, the core rod clamped by the clamp plate of the discharge mechanism 132 is hooked by the hook on the chain of the push rod assembly 21, and the reel therein is extracted. The core rod further moves right with the push rod assembly 21.

[0049] The push rod assembly 21 is provided with a sensing mechanism along the line, and when the core rod is sensed to be in place, the electromagnet of the control moving mechanism 211 is released. The impact force generated in the instant of the electromagnet release makes the core rod slip off the chain of the push rod assembly 21 and fall onto the push rod assembly 22.

[0050] Step 5: the fourth servo mechanism 25 continues to operate, the core rod is hooked by the hook on the chain of the push rod assembly 22 and is thrown out from the tail end and falls into the chain between the baffles under the action of the guide plate of the discharge rod assembly 23. At the same time, the third servo mechanism 24 continues to operate, the core rod is pushed by the push plate on the chain of the discharge rod assembly 23 to move left along the baffles, and finally falls into the groove of the feeding mechanism 112. A plurality of core rods are cyclically operated at fixed intervals.

[0051] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation according to the content of the present application, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
