In the existing equipment, the stacked sheets always face the condition that two adjacent sheets are sticky, separation of the sheets always exists, and a person skilled in the art adopts means such as release paper, air flotation separation and liquid spraying separation, but obvious inadaptation problems exist in the sheets positioned by pins by the means, and particularly the separation effect is almost ineffective due to the existence of positioning pin rods. In order to solve the above-mentioned problem, the positioning pin 32 includes a tightening portion 321 and a release portion 322 located at the upper end of the tightening portion 321, where the outer diameter of the tightening portion 321 is equal to the inner diameter of the sheet positioning hole to form an interference fit, and the "equal" allows a certain error, so long as the sheet positioning hole and the tightening portion have full contact and cannot automatically fall off. The external diameter of release 322 is less than the internal diameter of sheet locating hole and forms the clearance and wear to establish, when the carrier board upwards rises a sheet thickness under the support of lifter, extrude the locating hole of the lamellar material that will be uppermost to the release portion of locating pin pole by the tight portion of wearing of locating pin pole, the lamellar material of the topmost just no longer is bound by the lifter this moment, the lamellar material that is uppermost lies in release portion and is had the clearance with release portion, and the next lamellar material adjacent with the lamellar material that is uppermost still is in the tight portion of wearing of lifter, the phenomenon of sticking just can not appear when the manipulator picks up the lamellar material that is uppermost, the sticky problem of adjacent lamellar material has effectually been solved. The whole locating pin rod is a tightening part below the self-releasing part, and the locating holes of all sheets are matched with the tightening part, so that the locating pin rod with a large length of the tightening part is more suitable for sheets with larger thickness, and the sheets are easier to separate from the locating pin rod during stripping.

In order to facilitate the sheet positioning hole to be more easily inserted into the positioning pin, a rod head 323 with a gradually reduced diameter is extended upwards from the upper end of the releasing portion 322 in the present embodiment.

In another embodiment, the tightening part 321 of the positioning pin 32 is disposed at a position of the positioning pin near the top end, the diameter of the positioning pin below the tightening part 321 is smaller than that of the tightening part to form the set part 320, and the positioning hole of the sheet material passes through the tightening part 321 and is sleeved on the set part 320 of the positioning pin to form a clearance fit. The penetrating and fastening part is thick, the positioning pin rods with two thinner ends are suitable for thin sheets, more sheets can be stacked, the situation that the sheets are difficult to separate is avoided, when the sheets separate, the sheets only pass through the penetrating and fastening part with a small distance on the positioning pin rods, the first-stage sheets can separate from the penetrating and fastening part smoothly under the action of external force, and the penetrating and fastening part can well limit the natural separation of the second-stage sheets or the separation of the adhesive force from the first-stage sheets. The sheet positioning hole at the sleeving part basically has no tension force with the sleeving part, and in a release state, the sheet is not subjected to the reaction force or interference of the sleeving part when rising relative to the positioning pin rod, so that the power consumption of the lifting mechanism is saved.

In other embodiments the number of guide rods and guide holes may be 3 or 4, respectively. Since the guide rods and the guide holes frequently rub during the lifting process, in order to ensure the replaceability of the guide holes, guide sleeve plates 316 are mounted on at least two top corners of the support plate, and guide holes 315 are provided on the guide sleeve plates 316, which are engaged with the guide rods 314. Four apex angles of the supporting plate can be provided with guide sleeve plates, the guide sleeve plates can be made of wear-resistant high polymer materials, and the guide sleeve plates can be arranged on the supporting plate in a screw locking mode, so that the worn guide sleeve plates can be replaced conveniently, or the guide holes on the guide sleeve plates can be adjusted conveniently to be matched with the guide holes on the guide sleeve plates, and in fig. 8, the guide sleeve plates are arranged on 4 apex angles of the supporting plate, but only two guide rods are matched with the guide holes on one diagonal angle of the supporting plate. When the independent storage plate is arranged on the storage seat, the guide rod is arranged on the storage plate, so that the bearing plate is sleeved on the guide rod of the storage plate, and the guide rod can be taken down from the mounting frame as an integral unit to change materials. When the material storage seat is installed on the installation frame, the installation frame is rotatably provided with a supporting rod 344 extending forwards and upwards, the supporting rod 344 is provided with a transverse rod 345 extending transversely, and the transverse rod 345 is provided with a static electricity eliminating nozzle 346 arranged towards the lamination sheet material on the bearing plate. When the storage plate or the bearing plate is required to be taken and placed from the mounting frame, the supporting rod can be turned downwards, more space is reserved for operators to operate, after the fully loaded bearing plate is placed back on the storage seat, the supporting rod is turned back to the original position, and the occupied space for outward extension is not much, so that the operation is convenient.

When the storage and discharging device in the embodiment is applied to a machine tool for processing, in combination with the machine tool shown in fig. 9, the supporting plate is fully loaded with stacked sheets, positioning holes in the sheets are all penetrated on positioning pin rods of the storage plate, the storage plate is fixed on the mounting frame, when a manipulator takes materials, the lifting mechanism lifts the lifting rod upwards by one sheet thickness, the supporting plate lifts the sheet by one sheet thickness upwards relative to the storage plate, the positioning holes in the uppermost sheet on the supporting plate are separated from the penetrating parts of the positioning pin rods to reach the releasing parts, the manipulator takes the uppermost sheet, and the cycle is performed until the lifting mechanism lifts the supporting plate to the upper part of the positioning pin rods through the lifting rod, and the sheets on the supporting plate are taken by the manipulator. The lifting mechanism returns to the initial position, the bearing plate falls back onto the material storage plate, an operator takes the material storage plate off the mounting frame, and the material storage plate full of the carrier material is replaced to continue feeding. When the machine tool needs to perform clamp adjustment and tool changing operation, the installation frame can be pushed to one side of the machine tool body, the installation frame can be moved by manual pushing or electric control, and the installation frame can be positioned by the front side of the machine tool body through the positioning column in cooperation with the limiting block and the buckling mechanism.
