The prior art roll winding system generally includes a finished product storage rack and a winding device. The winding device is used for winding and packaging the finished coiled material according to a certain length specification. When the winding device packs, the winding is stopped, namely, the input of the coiled materials is stopped. The finished product storage rack is used for buffering and storing finished product coiled materials continuously output by a production line, and the shutdown of the coiled material production line caused by the fact that the coiling device stops coiling is avoided. Meanwhile, the finished product storage rack also plays a role in adjusting the output speed of the production line coiled material and the winding speed of the winding device.

Store and be equipped with first spring frame between frame and the coiling mechanism, first spring frame is used for adjusting store the tension of coiled material between frame and the coiling mechanism. In the prior art, because synchronous start and stop are difficult to realize between storage frame, brake motor and the coiling mechanism, and first spring frame is limited to the length and the tension control range of coiled material. The coiling mechanism can excessively drag the coiled material when the coiling is started quickly, and easily causes the internal damage of the finished coiled material and the impact and abnormal sound of the coiling system equipment. When the rolling device stops rolling, a small amount of stacked finished coiled materials between the storage rack and the rolling device can fall to the ground, and the appearance is damaged. Both internal and external damage to the coil can seriously affect the final product quality of the finished coil.

The movable bouncing roller assembly and the fixed roller assembly are adopted, and the length and the tension of the coiled material arranged on the bouncing roller assembly and the fixed roller assembly are adjusted by adjusting the position relation between the movable bouncing roller assembly and the fixed roller assembly. When the coiled material is relaxed, the distance between the bouncing roller component and the fixed roller component is increased; when the coiled material is tightened, the distance between the bouncing roller assembly and the fixed roller assembly is reduced. The problem that the length and the tension adjusting range of the bouncing frame to the coiled material are limited can be effectively solved by increasing the distance between the bouncing roller assembly and the fixed roller assembly and increasing the number of guide rollers on the bouncing roller assembly and the fixed roller assembly.

Example 1

As shown in fig. 1, 2, 3 and 4, the servo bouncing device of the present embodiment includes a first frame 10, and a fixed roller assembly 20, a bouncing roller assembly 30, a servo driving part and a sensor assembly 70 mounted on the first frame 10. The fixed roller assembly 20 and the bouncing roller assembly 30 are arranged along the up-down direction; the coiled material is arranged in the fixed roller component 20, the bouncing roller component 30 and the sensor component 70 in a penetrating way; the servo driving part drives the bouncing roller assembly 30 to move along the up-and-down direction according to the tension change signal of the coiled material obtained by the sensor assembly 70; the dancer roller assembly 30 adjusts the length of the web and maintains the web tension by moving toward and away from the fixed roller assembly 20.

The dancer roller assembly 30 and the fixed roller assembly 20 are used for web threading. The pop-up roller assembly 30 may be disposed at an upper portion of the first frame 10, and the fixed roller assembly 20 is correspondingly disposed at a lower portion of the first frame 10. The number of guide rollers on the pop-up roller assembly 30 and the fixed roller assembly 20 is set to 2.

The sensor assembly 70 may be positioned at the input or output end of the web. The servo drive assembly includes an actuating tip that is servo linearly movable and is fixedly coupled to the pop-up roller assembly 30 to drive the pop-up roller assembly 30 in servo linear movement.

In the present embodiment, the roll having a certain width and thickness is heavy, and the pop-up roller assembly 30 and the fixed roller assembly 20 are disposed in the up-down direction, it is not necessary to add the tension roller assembly in case of a large span, so as to avoid the roll suspension bending deformation and the interference of the roll with the first frame 10. The movable bouncing roller assembly 30 and the fixed roller assembly 20 are adopted, and the position relationship between the two is adjusted, so that the length and the tension of the coiled material arranged on the bouncing roller assembly are adjusted. As the web relaxes, the distance between the dancer roller assembly 30 and the fixed roller assembly 20 increases; as the web is being tensioned, the distance between the pop-up roller assembly 30 and the fixed roller assembly 20 decreases. By increasing the distance between the bouncing roller assembly 30 and the fixed roller assembly 20 and increasing the number of guide rollers on the bouncing roller assembly 30 and the fixed roller assembly 20, the problem that the length and tension adjustment range of the roll material by the bouncing frame are limited can be effectively solved. After the sensor assembly 70 obtains the tension change of the web, it sends a signal to the servo driving part in real time, and the servo driving part rapidly drives the bouncing roller assembly 30 to move in the up-and-down direction, so as to adjust the length of the web and maintain the tension of the web, thereby achieving the effects of buffering and storing the excess web and maintaining the constant tension of the web.

Preferably, the servo drive components include a servo motor assembly 40, a transmission assembly and a guide rail assembly 60; a transmission assembly and guide rail assembly 60 is mounted on the first frame 10 in the up-down direction; a guide track assembly 60 is coupled to the bouncing roller assembly 30; the transmission assembly is connected with the bouncing roller assembly 30 or the guide rail assembly 60; the servo motor assembly 40 drives the pop-up roller assembly 30 on the rail assembly 60 by driving the transmission assembly. The servo motor assembly 40 includes a servo motor and a precision reducer. The servo motor assembly 40 is fixedly installed at a lower portion of the first frame 10 to lower a center of gravity and facilitate installation and maintenance. The transmission assembly can adopt chain transmission, belt transmission, gear rack transmission, ball screw transmission or the like. The drive assembly includes an actuating end that can be directly connected to the pop-up roller assembly 30 or indirectly connected to the pop-up roller assembly 30 via the guide track assembly 60 to effect the transfer of the servo linear motion. The transmission assembly may be configured as a single-sided drive or a left-right double-sided drive of the first frame 10 according to power requirements. The track assembly 60 is used to support the bouncing roller assembly 30 and may be provided as a single or dual set of supports. In the case of the double support, the guide rail assemblies 60 are respectively located at both ends of the pop-up roller assembly 30, and the guide rail assemblies 60 face the front-rear direction or the left-right direction of the first frame 10.

Further, the transmission assembly is a chain transmission assembly 50, and the chain transmission assembly 50 comprises a first sprocket rotating shaft 51, a second sprocket rotating shaft 52 and a transmission chain 53; a first sprocket rotating shaft 51 is installed at the upper part of the first frame 10, and a second sprocket rotating shaft 52 is installed at the lower part of the first frame 10; the two groups of transmission chains 53 are symmetrically arranged on the left side and the right side of the first frame 10 and are connected with the first chain wheel rotating shaft 51 and the second chain wheel rotating shaft 52; two sets of drive chains 53 are fixedly connected to the bouncing roller assembly 30 or the track assembly 60, respectively. The first sprocket rotating shaft 51 and the second sprocket rotating shaft 52 respectively include a sprocket, a rotating shaft and a bearing seat.

The open end or a section of the transmission chain 53 is directly or indirectly connected with the bouncing roller assembly 30, which is equivalent to an execution end, and further drives the bouncing roller assembly 30 to move in the up-and-down direction, so that the transmission of the servo linear motion is completed.

Further, the rail assembly 60 includes a first rail 61, a second rail 62, and a roller set 63; the roller group 63 includes at least 2 rollers arranged in parallel in the up-down direction; a first guide rail 61 and a second guide rail 62 are fixedly installed on the first frame 10 and respectively contact with the roller groups 63 along the front-back direction; the guide rail assemblies 60 are provided in two sets and symmetrically installed at the left and right sides of the first frame 10. The roller groups 63 and the associated supports on the left and right sides form a slide 64, and the slide 64 provides a platform that can move linearly in the up-down direction. The bouncing roller assembly 30 is fixedly mounted on a ramp 64. Because the guide rail assembly 60 faces the front and back direction of the first frame 10, the roller group 63 on one side adopts more than 2 rollers arranged in parallel, which can effectively avoid the sliding table 64 from rotating and deviating around the rollers under the driving force of the transmission assembly, so that the sliding table 64 keeps planar stability in motion.

The adoption of the arrangement mode of the bouncing roller component 30 on the upper part is beneficial to the servo bouncing device to rapidly output the coiled material. When a rapid web output is required (i.e., the pop-up roller assembly 30 needs to be close to the fixed roller assembly 20), the pop-up roller assembly 30 can be rapidly moved downward by its own weight and the driving force provided by the servo driving part, thereby rapidly outputting a large amount of the web. Conversely, with the pop-up roller assembly 30 in the down setting mode, the servo drive means would need to overcome the self weight of the pop-up roller assembly 30 and drive it in rapid upward movement to effect the output of a large number of rolls. The servo drive components require more power in order to achieve the same output web response. Therefore, to achieve a faster web output response, a pattern of fixed roller assembly 20 down and dancer roller assembly 30 up is used.

The double row of the driving chain 53 passes through the inside of the first housing 10 on one side and the area between the first guide rail 61 and the second guide rail 62 on the other side. The double-row transmission chain 53 is an open chain, and two ends of the opening are fixed on the upper side and the lower side of the sliding table 64 of the guide rail assembly 60.

In this embodiment, taking the left or right rail assembly 60 as an example, the first rail 61 is fixedly installed on the rear surface of the first frame 10, and the second rail 62 is fixedly installed behind the first rail 61 through a plurality of brackets.
