Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

A manipulator material overlapping prevention feeding device comprises two parallel guide rails 10. A sheet stock support frame 12 is arranged between the two guide rails 10 and is parallel to the guide rails 10, and a feeding station 14 for stacking sheet stock workpieces is arranged at one end of the sheet stock support frame 12. A waiting station 16 and a weighing station 18 are provided on the sheet stock support 12. The weighing station 18 is provided with a position sensor (not shown) for detecting the presence or absence of a sheet material workpiece at the weighing station 18 and a weight sensor 20 for measuring the weight of the sheet material workpiece at the weighing station 18. The standby station 16 is provided with a position sensor (not shown) for monitoring whether there is a sheet workpiece at the standby station 16.

The inner sides of the two guide rails 10 are provided with 3 sets of manipulator fingers 22 for gripping the sheet material workpiece corresponding to the loading station 14, the weighing station 18 and the waiting station 16. The 3 sets of robot gripping fingers 22 are all fixedly mounted on slides (not shown) which are movable on the guide rails 10.

The robot gripping fingers 22 include two gripping plates 24 respectively disposed on the inner sides of the guide rails 10, and a cylinder (not shown) for driving the gripping plates 24 to reciprocate toward the other guide rail 10, and the gripping plates 24 are provided with a plurality of rollers 26 for fixing the sheet material workpiece. The rollers 26 are disposed on the clamping plate 24 at equal intervals along the edge of the sheet work piece, and the axial direction of the rollers 26 is perpendicular to the clamping plate 24. The rollers 26 are made of rubber or plastic and are convenient for clamping metal plates.

When the utility model is used, the slide block moves to drive the leftmost manipulator clamp finger 22 to take off a sheet material workpiece 28 from the stacking device arranged at the feeding station 14, then the sheet material workpiece is sent to the waiting station 16, and then the feeding station 14 is continuously carried out to take off the sheet material workpiece; at this time, the middle robot gripper 22 sends the sheet workpiece from the standby station 16 to the weighing station 18, and the sheet workpiece is weighed by the weight sensor 20, and whether or not there is any stack is confirmed, and if there is no stack, the sheet workpiece is sent to a press machine (not shown) by the rightmost robot gripper 22 to perform a press operation. The three manipulator fingers 22 reciprocate in this manner to complete the detection and feeding actions in sequence. The position sensor and the weight sensor 20 used in the present invention are sensors that are well known in the art and are conventionally used, and only play a fundamental role in the present invention, and thus the model and the like thereof are not described in detail.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
