The clamping and conveying structure 1 comprises an upper layer conveying belt 11 and a lower layer conveying belt 12 which are arranged side by side. The vertical setting of frame 9, centre gripping conveying structure 1, pallet 3, counter sensor 7 and roof 8 all locate the homonymy (left side or right side) of frame 9, and pallet 3 locates the rear portion of frame 9, and ejection of compact platform 4 is located the rear of frame 9. The plurality of fabrics 2 are stacked back and forth on the outfeed platform 4 by the pallet 3 to form a fabric stack 5.
Wherein, pallet 3 can 60 degree indexing rotation, pallet 3 includes pivot 32 and control side by side setting and synchronous pivoted two piece discs 31, and two piece discs 31 are located the both sides of centre gripping conveying structure 1 respectively. Disc 31 is coaxially arranged on rotating shaft 32, and strip-shaped openings 33 on the disc are in one-to-one correspondence. The rotary shaft 32 is provided on the frame 9 in the left-right direction, and is driven to rotate in an indexing manner by a corresponding structure.
Wherein, disc 31 is a disc, which is arranged along the left and right directions, six bar-shaped openings 33 which are matched with fabric 2 are arranged on the disc in an indexing way around the circle center, and the disc can be driven by a rotating shaft to rotate in an indexing way. Each strip opening 33 can be rotated to the top of pallet 3 as pallet 3 is indexed. When the strip-shaped opening 33 is positioned on top of the pallet 3, it is positioned in a front-to-back direction, it is opened forward, its lower side is flush with the lower conveyor belt 12 and its upper side is flush with the upper conveyor belt 11 to ensure that the fabric 2 can enter the strip-shaped opening 33. The length of the strip-shaped openings 33 is greater (in particular slightly greater, e.g. 2-4cm greater than the length of the fabric 2) than the length of the fabric 2. The lower conveyor belt 12 extends rearward relative to the upper conveyor belt 11, the rear end of the upper conveyor belt 11 being located in front of the top strip-shaped opening 33; the foregoing arrangement ensures that the fabric 2 is fed back into the top strip-shaped opening 33.

1-3, the counting sensor 7 in the embodiment of the invention is a photoelectric sensor, which is vertically downward arranged on the frame 9 and is located right above the middle of the strip-shaped opening 33 at the top and is located between two discs 31.
1-3, the notch 42 in the embodiment of the present invention is a rectangular notch disposed along the front-rear direction, and its left and right sides are located adjacent to the outer sides of the corresponding sides of the pallet 3.
Referring to fig. 1-3, the top plate 8 in the embodiment of the present invention is a rectangular plate disposed in the left-right direction, which is driven to move up and down by a cylinder on the frame 9, and which is located directly under the bar-shaped opening 33 at the rear upper portion. The cylinder is vertically arranged on the frame 9 and is positioned between the two discs 31, and the upper end of the telescopic rod is fixedly connected with the lower side of the top plate 8.
Preferably, the intersection of the underside of the strip-shaped opening 33 and the outer edge of the disc 31 in the embodiment of the present invention is an arc-shaped transition structure 34. The arcuate transition 34 is arcuate to provide a smooth transition to ensure that the fabric 2 is able to exit the strip opening 33.
Referring specifically to fig. 1-2 and 5, pallet 3 in the present embodiment is capable of indexing rotation of 60 deg., with an angle of 60 deg. between adjacent two of the strip openings 33, and with the strip openings 33 on two discs 31 aligned one to one.
