If the first transfer support roller 11 and the second transfer support roller 12 are arranged to have the same height, the use thereof is not affected. The transfer conveyor 1 is located outside the transfer support rollers, and the coiler 2 is located above the first transfer support roller 11 and the second transfer support roller 12. The coiler 2 is rotatably mounted on a fixed frame.

As shown in fig. 2, the transfer unit, the turnover unit, and the storage unit are fixedly mounted on a frame 6 capable of transverse reciprocation, which is capable of transverse reciprocation with respect to the coiler.
In the embodiment shown in fig. 1 and 2, the length of the conveyor belt of the inverting unit, the storage unit can be determined, which is easier to achieve when tensioning the inverting conveyor belt 3 and the storage conveyor belt 4.
As shown in fig. 3, when the turnover unit is located outside the conveying unit, the storage unit is located at the lower side of the conveying unit, and the third transfer support roller 13 is disposed at a height below the first transfer support roller 11 and the second transfer support roller 12, the second turnover support roller 32 can use the same support roller as the first storage support roller 41 to form a clamping support roller 72, the turnover conveyor belt and the storage conveyor belt use the same conveyor belt to form a clamping conveyor belt 7, and correspondingly, the first turnover support roller 31 becomes a support roller 71, the second storage support roller 42 becomes a support roller 73, and the clamping conveyor belt 7 has both functions of clamping a fiber strip and storing a fiber strip.
In operation, the fiber strips output by the carding machine are orderly looped on the transfer conveyor belt 1 through the coiler 2. The transfer conveyor 1 and the coiler 2 run at a certain speed ratio. The fiber ribbon 21 is clamped by the transfer conveyor 1 and the clamping conveyor 7 when the fiber ribbon 21 moves to one end of the conveyor following the transfer conveyor 1, and the clamped fiber ribbon 21 turns over to become a turned fiber ribbon 22 when the clamped fiber ribbon 21 moves to the upper plane of the clamping conveyor 7.

During operation, the fiber strips output by the carding machine are orderly coiled on the transfer conveyor belt 1 through the coiler 2. The two conveyor belts follow the frame 6 and do transverse reciprocating motion relative to the coiler 2; at the same time, the transfer conveyor 1 delivers the fibre sliver 21 at a certain speed into the clamping area with the clamping conveyor 7. The sliver is clamped by the two conveyor belts, and the clamped sliver is turned over when moving to the upper plane of the clamping conveyor belt 7.

While both nip belt support rollers of the transfer conveyor 8 may be driven or one may be powered.
Furthermore, the transfer support rollers can be only a first transfer support roller and a second transfer support roller which are arranged in parallel, and the overturning unit and the storage unit overturn the fiber strips conveyed by the transfer conveyor belt.
In the above various embodiments, the monitoring unit 5 includes two pairs of sensors for monitoring the storage amount of the fiber strand, one pair of sensors 51 for monitoring the upper limit and the other pair of sensors 52 for monitoring the lower limit, both pairs of storage amount sensors being mounted on the storage conveyor belt where the turnover of the fiber strand is completed.
When the storage and overturning device is applied, at least two pairs of sensors for monitoring the storage quantity of the fiber strips are arranged in each set of fiber strip storage and overturning device. Both pairs of storage sensors are mounted near the top of the belt where the sliver is turned. As shown in fig. 1 to 6.
The storage of the fiber strand in the device is monitored by two pairs of storage sensors 52 and 51. Wherein: 52 is a fiber rod storage amount upper limit sensor, and 51 is a fiber rod storage amount lower limit sensor.
When the flipped sliver take-off point is completed, between the two pairs of sensors, the carding machine is run at the original speed. When the storage of the sliver on the belt reaches the upper limit, the carding machine starts to run at a lower speed. When the storage of the sliver on the belt reaches a lower limit, the carding machine starts to run at a higher speed.
The drawing point of the fiber strip on the fiber strip storage and turning device depends on a carding machine to automatically adjust the production speed. The monitoring unit is connected with the control device, and the control device is connected with the carding machine and controls the running speed of the carding machine.
The lower running speed and the higher running speed of the carding machine are within +/-10 percent. The carding machine makes such a change in speed that, in existing production practice, it has proved that it does not have a significant effect on the quality of the output sliver.
