Technical Field

The utility model relates to the technical field of machining tool storage and taking equipment, in particular to an annular chain conveying device for a tool magazine for vertically storing and taking tools.

Background

Along with the increasing variety of machining tools, the use amount of the tools is increased, the use frequency of the tools is increased, and the requirements of people on the automation degree of tool library management are also increased.

The prior art tool magazine or tool cabinet has various types, different structures, various advantages and various defects. Some tools are stored or taken out vertically, such as numerical control tools. In the tool magazine for vertically storing and taking tools in the prior art, the vertically stored tools are directly inserted into the tool holes of a plurality of layers of storage plates of the three-dimensional magazine and are stored or taken by a taking and placing system. The cutter can be taken out only by lifting a section of height from the cutter hole and enabling the bottom end of the cutter to be higher than the top end face of the cutter hole and then horizontally moving, and the mechanical gripper needs to occupy a considerable height space during operation. It will be appreciated that such a configuration comes at the cost of reducing the number of stored vertically placed tools, i.e. the number of stored tools per unit space is reduced by a geometric multiple. Furthermore, although the control system of the tool magazine in the prior art can receive the input of the information about tools at the input end of the control system by the remote control of the mobile phone, if a plurality of tools need to be fetched at a time, the tool magazine in the prior art still needs to stand at the position of manually fetched and placed tools, and the fetching and placing system of the tool magazine needs to wait for a long time to run the required tools from different storage spaces of the tool magazine to the position of manually fetched and placed tools; otherwise, if a plurality of cutters need to be stored at a time, one cutter needs to be manually placed at the position of manually taking and placing the cutters, the taking and placing system of the cutter library takes the cutters away, then the second cutter is placed, the taking and placing system of the cutter library waits for running the cutters into the preset cutter holes of the preset storage plate of the preset storage space, and then the above operation is repeated again to store the second cutter; the technical problem that a plurality of cutters are manually waited for each time is overlong in the field of cutter libraries in the prior art, which is not solved well yet.

In order to solve the technical problems, the applicant provides a technical conception that a rectangular cutter disc provided with a plurality of vertical cutters is placed on a pair of horizontal supporting plates of each storage space in a vertical grid-shaped cutter storage library, and the vertical rows and the horizontal rows of a plurality of storage spaces are arranged at equal intervals; and then the control system of the prior art is used for controlling a horizontal driving mechanism, a vertical driving mechanism and a bidirectional telescopic fork in the picking and placing system of the prior art, the bidirectional telescopic fork can horizontally move into and out of the storage space, only a small amount of space within 1 cm is needed for moving up and down, a rectangular cutter disc with a plurality of vertical cutters is taken out or stored, and then the vertical cutters are taken out of the rectangular cutter disc from the bidirectional telescopic fork and placed on a conveying device or the vertical cutters are taken out of the conveying device and placed on cutter hole seats of the rectangular cutter disc from the bidirectional telescopic fork of the cutter library through the cutter transfer mechanism of the cutter library.
