Description

Technical Field

[0001] The invention relates to automated mechanical equipment, in particular to a blank warehouse discharging device with high-speed buffering descent. Background Art

[0002] In order to improve the degree of automation and reduce manual supervision in the automated production process, a technical solution of directly discharging materials from the blank warehouse is adopted in the blank processing production line. The blank warehouse is a blank plate structure in the form of a multi-layer shelf that can be easily accessed and arranged in a box body that is connected from front to back. The neatly arranged blanks are placed on the blank plate. The conveyor belt transmission mechanism is set below the blank warehouse. As the blank warehouse descends, the blank plates in the blank warehouse are automatically conveyed from bottom to top by the conveyor belt transmission mechanism. The lifting of the blank warehouse is controlled by a cylinder, which has the characteristics of high efficiency and low cost. However, due to the reasons of the cylinder transmission structure, when the blank warehouse descends and the blank plate is lifted by the conveyor belt, the conveyor belt will have a large impact on the blank plate, causing the blanks placed on the blank plate to scatter. Summary of the invention

[0003] The purpose of the present invention is to address the above defects and to provide a blank warehouse discharging device with simple structure and high-speed buffer descent.

[0004] The object of the present invention is achieved as follows: a high-speed buffer descending blank library discharging device of the present invention comprises a frame, a blank library, a lifting cylinder and a conveyor belt transmission mechanism, guide pillars are arranged on both sides of the frame, the blank library is arranged on the guide pillars on both sides of the frame, and the lifting cylinder is fixed below the blank library. It is characterized in that a first positioning mechanism is arranged on one side of the blank library, the first positioning mechanism comprises a first row of positioning recesses arranged from top to bottom, a first rotating shaft is arranged on the frame, a first positioning claw is fixed on the first rotating shaft, the first positioning claw is connected to the first positioning cylinder, and one of the recesses in the first row of positioning recesses corresponds to the blanks respectively. One of the layers of blank plates in the blank library is provided with a sensor corresponding to each of the above-mentioned recesses; a second positioning mechanism is provided on the other side of the blank library, the above-mentioned second positioning mechanism includes a second column of positioning recesses arranged from top to bottom, a second rotating shaft is provided on the frame, a second positioning claw is fixed on the second rotating shaft, the second positioning claw is connected to the second positioning cylinder, each recess in the above-mentioned second column of positioning recesses corresponds to one layer of blank plates in the blank library; the above-mentioned first column of positioning recesses and the second column of positioning recesses each have a recess corresponding to the same layer of blank plates, and the upper edge of the recess corresponding to the second column of positioning recesses is higher than the upper edge of the recess corresponding to the first column of positioning recesses.

[0005] The upper edge of the depression corresponding to the second column of positioning depressions is 0.2 to 1 cm higher than the upper edge of the depression corresponding to the first column of positioning depressions.

[0006] The first positioning claw may also be set to a non-working state.

[0007] The high-speed buffered descending blank library discharging device of the present invention, when working, the lifting cylinder drives the blank library to descend, and when the first positioning mechanism senses the sensor in the first column of positioning recesses at the bottom, the first positioning cylinder and the second positioning cylinder work simultaneously, and the first positioning claw and the second positioning claw simultaneously extend into the recesses corresponding to the first column of positioning recesses and the second column of positioning recesses, the first positioning claw first positions the blank library, and the blank library stops descending, and at this time the blank plate has no contact with the conveyor belt transmission mechanism; then the first positioning cylinder separates the first positioning claw from the first column of positioning recesses, and since the upper edge of the recess corresponding to the second column of positioning recesses is higher than the upper edge of the recess corresponding to the first column of positioning recesses, the blank library continues to descend, and the second positioning claw positions the blank library for the second time, and at this time the conveyor belt transmission mechanism contacts the blank plate and separates the blank plate from the blank library, and the conveyor belt transmission mechanism works to convey the blank plate out of the blank library.

[0008] In the case where no blank is loaded on the blank plate, the first positioning claw of the device can be set to a non-working state to improve work efficiency.

[0009] The present invention adopts two positioning methods in the process of the blank library descending and the conveyor belt transmission mechanism holding up the blank plate, so it has the characteristic of precise positioning, overcomes the impact on the blank plate during the descending process of the blank library in the prior art, has the characteristics of good working stability and simple structure, and can also be switched to one-time positioning when the working requirements are not high, thereby improving work efficiency.
