[0020] Embodiment: A caching device for a combed cotton roll handling system comprises a cotton roll conveyor 3, a temporary storage accommodating slot, a material presence sensing device 11 and a roll pushing device. A plurality of temporary storage accommodating slots capable of accommodating cotton rolls are fixedly installed on one side of the cotton roll conveyor 3, and each temporary storage accommodating slot corresponds exactly to the position of each cotton roll on the cotton roll conveyor 3. The fixed end of the roll pushing device is fixedly installed on the other side of the cotton roll conveyor 3. The moving end of the roll pushing device can push the cotton roll 12 on the cotton roll conveyor 3 into the corresponding temporary storage accommodating slot. The material presence sensing device 11 can sense the cotton roll 12 in the temporary storage accommodating slot and transmit a signal to the controller of the combed cotton roll handling system. The controller of the combed cotton roll handling system controls the operation of the roll pushing device and the lifting trolley of the combed cotton roll handling system. The material sensing device 11 can be a photoelectric device fixedly installed on the side wall of the temporary storage tank. The side wall of the temporary storage tank is designed with a circular hole with two ends passing through at the corresponding photoelectric device. When the cotton roll 12 is pushed into the temporary storage tank, a barrier is formed. The photoelectric detection signal is read by the controller of the combing cotton roll handling system and transmitted to the lifting trolley above the combing. The lifting trolley can transport the cotton roll 12 in the temporary storage tank to the combing machine. If the photoelectric signal is not changed, that is, the cotton roll is always in the temporary storage tank, the roll pushing device will not push the next group of cotton rolls 12 into the temporary storage tank. The present invention sets a temporary storage tank at the end of the cotton roll conveyor 3 (towards the end of the combing machine), which can realize the temporary storage of the whole group of cotton rolls neatly, quickly and automatically, without affecting the operation of the strip winding machine, and at the same time, a certain buffer time is given to the docking and lifting trolley that transports the group of cotton rolls 12 to the combing machine, so that the overall operation of the system is smoother. In addition, the cotton rolls 12 in the temporary storage tank have not been transported away. Because the cotton roll conveyor 3 station has been cleared, another group (8) of cotton rolls 12 can be placed at the end of the cotton roll conveyor 3, thus forming a reserve of two groups (16) of rolls. At this time, the cotton roll storage is in a saturated state, which can effectively extend the allowable downtime of the strip winding machine. The strip winding machine can be cleaned or maintained in a planned manner during the interval time to avoid affecting the matching supply between the front and rear processes. Especially when multiple varieties of spinning are produced simultaneously and multiple conveyor lines are supplied simultaneously, the cotton roll semi-finished products are cached for the switched varieties, which solves the problem of cotton roll connection supply and reserve.

[0021] The cotton roll conveyor 3 is provided with an arc-shaped cotton roll holding platform 13 to achieve stable storage of the cotton rolls on the cotton roll conveyor 3.

[0022] The height of each temporary storage accommodating groove is lower than the height of the arc-shaped cotton roll holding platform 13 on the cotton roll conveyor 3, and an inclined feeding channel 14 is formed on one side of the temporary storage accommodating groove to be directly connected with the arc-shaped cotton roll holding platform 13. The temporary storage accommodating groove and the arc-shaped cotton roll holding platform 13 preferably form a height difference of about 100 mm, so that the cotton roll can smoothly roll from the conveyor to the temporary storage accommodating groove with the help of this height difference.

[0023] The inclined feed channel 14 on one side of the temporary storage tank is a trumpet-shaped structure whose width is greater at one end near the cotton roll conveyor 3 than at one end near the temporary storage tank. The gradually increasing inlet facilitates the smooth entry of the cotton roll into the temporary storage tank.

[0024] The temporary storage tank is a rectangular parallelepiped structure, and the distance between the two side walls of the temporary storage tank along the axial direction of the cotton roll is exactly equal to the distance between the two combing eyes of the combing machine, so as to ensure that the lifting trolley can accurately lift the cotton roll to the combing machine.

[0025] The temporary storage accommodating groove includes a support plate 6, a partition plate 1 and a stopper 5. The support plate 6 is fixedly connected to the cotton roll conveyor 3. The support plate 6 forms a horizontal plane on the side away from the conveyor and forms an inclined plane on the side close to the cotton roll conveyor 3. The inclined plane of the support plate 6 is connected with the arc-shaped cotton roll holding platform 13 of the cotton roll conveyor 3. A plurality of partition plates 1 and stopper 5 are fixedly installed on the support plate 6 at intervals along the axial direction of the cotton roll. Every two partition plates 1 form a group. Each group of partition plates 1, support plates 6 and stopper 5 located between each group of two partition plates 1 form a temporary storage accommodating groove. The groove structure composed of the partition 1, the support plate 6 and the stopper 5 can realize the stable positioning of the whole group of cotton rolls. The stopper 5 is preferably about 120mm higher than the support plate 6 to realize the axial limitation of the cotton roll. The partition 1 includes a first side wall and a second side wall. There is an obtuse angle between the first side wall and the second side wall. The end of the first side wall of the partition 1 is connected to the arc-shaped cotton roll holding platform 13 of the cotton roll conveyor 3. An inclined feeding channel 14 is formed between the first side walls of each group of partitions 1. A storage space for just one cotton roll is formed between the second side wall of each group of partitions 1 and the stopper 5. Each group of partitions 1 has two symmetrical pieces on the left and right. The first side walls of the two adjacent groups of partitions 1 are close to each other on the conveyor side. When they are close together, they are aligned with the gap between the cotton rolls. The second side wall at the end away from the conveyor is evenly distributed on the support plate 6 in a parallel shape.

[0026] The support plate 6 is provided with a plurality of first long strip mounting holes extending along the axial direction of the cotton roll, and the partition plate 1 is provided with a second long strip mounting hole extending perpendicular to the axial direction of the cotton roll, and the partition plate 1 is mounted on the support plate 6 by passing bolts through the first mounting holes on the support plate 6 and the second mounting holes on the partition plate 1. The position of the partition plate 1 on the support plate 6 can be adjusted by installing the long strip holes, so as to adjust the distance between each group of partition plates 1, and adjust the relative position between the partition plate 1 and the cotton roll conveyor 3, so as to ensure that the interval size of the cotton rolls at the cache position matches the combing spacing of the combing machine.

[0027] The temporary storage tank also includes a partition bracket 4, which is fixedly positioned with the bottom surface of the support plate 6, the ground and the column of the cotton roll conveyor 3. The support plate 6 is supported and positioned by the partition bracket 4, and the partition bracket 4 is preferably about 100mm lower than the conveyor column.

[0028] The roll pushing device includes a roll pushing bracket 2, a connecting rod 9 and a driving device. The roll pushing bracket 2 is fixedly mounted on the other side wall of the cotton roll conveyor 3. One end of the connecting rod 9 is hinged to the upper end of the roll pushing bracket 2, and the other end can just push the outer surface of the circumference of the cotton roll on the cotton roll conveyor 3. The driving device drives the connecting rod 9 to swing. The roll pushing bracket 2 can be a square sheet metal structure, one end of which is fastened to the conveyor by screws, and the other end is designed with a rotating shaft 7 that crosses the two surfaces. One end of the connecting rod 9 is sleeved at the middle position of the rotating shaft to realize a hinge connection.

[0029] The driving device is a cylinder 8, the cylinder body of the cylinder 8 is hinged to the lower end of the roll push support 2, the piston rod of the cylinder 8 is hinged to the middle of the connecting rod 9, at least one push rod 10 arranged at intervals is fixedly installed at the end of the connecting rod 9, and the end of the push rod 10 is provided with an arc contact surface matching the outer side of the circumference of the cotton roll. The cylinder 8 is preferably a cylinder 8 with a Y-shaped fork, and the push rods 10 are preferably three parallel and spaced. When the piston rod of the cylinder 8 performs a telescopic action, it drives the connecting rod 9 to rotate at a certain angle around the rotating shaft, thereby realizing that the push rod 10 of the conveyor cotton roll station pushes the cotton roll in the oblique downward direction of the cotton roll.

[0030] When the cotton roll is transported to the combing machine on the conveyor, the travel switch at the tail end of the conveyor detects that the cotton roll is in place, and the signal is also transmitted to the controller of the combing cotton roll handling system. The controller of the combing cotton roll handling system controls the cylinder 8 of the roll pushing device to move, push the cotton roll into the temporary storage tank, and complete the release of the conveyor cotton roll station. When the cotton roll rolls into the temporary storage tank and happens to be at the detection station of the photoelectric reflection, the signal is randomly read by the controller of the combing cotton roll handling system and notified to the lifting trolley above the combing. If the signal is not changed, that is, the cotton roll is always in the temporary storage tank, the roll pushing device will not push the next group of cotton rolls onto the bracket. Such a design can also avoid the phenomenon of mistaken roll pushing when other foreign objects interfere with the photoelectric signal.
