Description

Spring mattress constant linear velocity rolling device

Technical Field

The invention belongs to the field of winding, and particularly relates to a spring constant linear speed rolling device.

Background

Simmons is a common article in daily life and comprises a cloth layer and a spring, wherein the cloth layer forms a bag to wrap the spring inside. Because the spring mattress has larger volume and is not beneficial to transportation, the spring mattress needs to be compressed and then wound on a scroll before transportation.

Disclosure of Invention

The invention provides a constant linear speed rolling device for a Simmons bed.

A spring constant linear velocity rolling device comprising: the device comprises a winding disc, a lower driving roller, an upper driven roller, a lower driven roller, a Simmons, a first roller, a mandrel, a second roller, a second lever, a first lever, a tensioning spring, a rotating shaft and a distance sensor.

The coiling disc rotates at a constant linear speed V1 under the drive of the driving device and coils the spring;

the upper driven roller and the lower driven roller passively roll under the friction of the Simmons to initially compress the Simmons. After the driven roller is initially compressed, the surface of the original rugged Simmons is relatively flat.

The upper driving roller and the lower driving roller are driven by a driving device (such as a servo motor) to rotate at a constant linear speed V2, so that the Simmons is compressed secondarily, and V2= 0.95V1.

If v2=v1, after the spring bed is compressed by the pressure of the driving roller in the vertical direction, the spring in the spring bed is compressed, so that the cloth layer may form wrinkles. Here, since V2 is slightly smaller than V1, the spring is pulled between the take-up reel and the drive roller, compressed in the vertical direction, and pulled in the horizontal direction, so that the spring becomes thinner and has no wrinkles.

However, as the reel continuously winds the Simmons, the radius thereof is continuously increased, and if the reel rotates at a constant rotation speed, the linear speed at which the reel winds is continuously increased. If the V2 value is unchanged, the rotation speed difference between the rolling disc and the driving roll is larger and larger, the tension born by the spring is also larger and larger, and the spring is likely to be broken. Therefore, it is necessary to rotate the take-up reel at a constant linear speed.

For this purpose, the device is also provided with a winding disc radius detection mechanism, a first lever and a second lever of the winding disc radius detection mechanism are rotatably connected to the rotating shaft, one end of the first lever is rotatably connected with a first roller, the first roller is abutted against a mandrel of the winding disc, one end of the second lever is rotatably connected with a second roller, the second roller is abutted against the outer edge of the winding disc, a tension spring is arranged between the first lever and the second lever, and a distance sensor (such as a laser ranging sensor) is arranged at the other ends of the first lever and the second lever. And measuring and calculating the distance between the first roller and the second roller through a distance sensor, thereby obtaining the radius of the winding disc.

The controller adjusts the rotating speed of the winding disc according to the real-time radius of the winding disc, so that the winding disc winds the Simmons at a constant linear speed V1.

The invention can effectively compress the Simmons, reduce the volume during transportation and reduce the transportation cost.

Example 1

A spring constant linear velocity rolling device comprising: 1-rolling disc, 2-lower driving roller, 3-upper driving roller, 4-upper driven roller, 5-lower driven roller, 6-Simmons, 7-first roller, 8-mandrel, 9-second roller, 10-second lever, 11-first lever, 12-tensioning spring, 13-rotating shaft and 14-distance sensor.

The coiling disk 1 rotates at a constant linear speed V1 under the drive of a driving device (such as a servo motor) and coils the spring 6;

the upper driven roller 4 and the lower driven roller 5 roll passively under the friction of the Simmons, and the Simmons is primarily compressed. After the driven roller is initially compressed, the surface of the original rugged Simmons is relatively flat.

The upper driving roller 2 and the lower driving roller 3 are driven by a driving device (such as a servo motor) to rotate at a constant linear speed V2, so as to compress the simmons secondarily, wherein v2= 0.95V1.

If v2=v1, after the spring bed is compressed by the pressure of the driving roller in the vertical direction, the spring in the spring bed is compressed, so that the cloth layer may form wrinkles. Here, since V2 is slightly smaller than V1, friction is formed between the upper and lower driving rolls 2 and 3 and the simmons, so that the upper and lower driving rolls 2 and 3 axially compress the simmons and simultaneously stretch the simmons fabric and the springs in the fabric in the tangential direction, and the simmons can be made thinner without wrinkles.

The device is also provided with a winding disc radius detection mechanism, a first lever 11 and a second lever 10 of the winding disc radius detection mechanism are rotatably connected to a rotating shaft 13, one end of the first lever 11 is rotatably connected with a first roller 7, the first roller 7 is abutted against a mandrel 8 of the winding disc 1, one end of the second lever 10 is rotatably connected with a second roller 9, the second roller 9 is abutted against the outer edge of the winding disc 1, a tension spring 12 is arranged between the first lever 11 and the second lever 10, and a distance sensor 14 (such as a laser distance measuring sensor) is arranged at the other ends of the first lever 11 and the second lever 10. The distance between the first roller 7 and the second roller 9 is measured by a distance sensor 14, so that the radius of the winding reel 1 is determined.

A controller (not shown) adjusts the rotational speed of the take-up reel 1 according to the real-time radius of the take-up reel 1 so that the take-up reel 1 winds the simmons at a constant linear velocity V1.

Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments.
