JP6954599B2 - Machine tool loader and its cover structure - Google Patents

Description

The present invention relates to a loader device provided for delivery of workpieces and a cover structure thereof in machine tools such as NC lathes and multi-tasking machines.

A loader device is incorporated for the purpose of carrying a work to be machined into a machine tool, discharging the machined work, and handing it over to the next process.
However, the organization of the production line differs greatly depending on the workpiece to be machined, the processes before and after the machine tool, and the like.
Further, in recent years, the loader device is greatly extended to the left or right side of the main body of the machine tool so that the work can be directly transferred between the peripheral machines and the measuring machines in the pre-process and the post-process of the machine tool. In some cases, we will prepare for it.

Conventionally, according to the specifications required by the user, the work delivery position is manufactured by extending the work to the left, right, and further to the left (extension to the left) and to the right (extension to the right). Covers were manufactured and attached accordingly.
With this, it was not possible to install the loader device or manufacture the cover until the configuration of the user's production line was decided, or it was not possible to respond promptly to the user's specification change.
Especially when the specifications are changed locally according to the user's request, it may be a difficult task such as having to remove the cover of the machine tool that has been assembled and attach a newly manufactured cover. there were.

Patent Document 1 discloses a technique in which an auxiliary guide, a movable slider, and the like are detachably provided when extending a rail to a loader device, but the cover structure cannot be changed according to the specifications.

Japanese Unexamined Patent Publication No. 2016-175154

An object of the present invention is to provide a loader device and a cover structure thereof, which can easily change the specifications of a loader device provided in a machine tool and can easily change the attachment of a cover accordingly.

The loader device of the machine tool according to the present invention is a loader device provided in the machine tool, the loader device has a traveling rail portion attached to the machine tool, and the traveling rail portion is attached to a main body portion of the machine tool. It is characterized in that the delivery position of the work can be moved and switched in the left-right direction of the machine tool by having the mounting portions at a plurality of positions as well as being mounted.
Here, the left and right of the machine tool are expressed as left and right for convenience toward the front surface having the operation panel, operation unit, etc. of the machine tool, and are the positions where the work to be machined is carried in and out of the machine tool. It means that it is possible to switch to either the front or rear side of the traveling rail portion on which the loader device travels.

In the present invention, the machine tool is a machine tool that performs machining, welding, overlaying, laser machining, etc. on the work.
For example, NC control lathes, machining centers, multi-tasking machines and the like can be mentioned as examples.
In the loader device, the traveling rail portion is travel-controlled by a hand portion that handles the workpiece and a servomotor or the like.

In the present invention, having mounting portions at a plurality of positions of the traveling rail portion means that, for example, when the traveling rail portion of the loader device is fixed to the main body portion of the machine tool with bolts or the like via a bracket, the traveling rail portion is attached to the traveling rail portion. It means having mounting parts such as bolt insertion holes at a plurality of positions at a predetermined pitch.
In this case, contrary to the above, a plurality of brackets may be provided on the main body side at a predetermined pitch.
In this way, in addition to switching the mounting position of the bracket of the main body and the traveling rail to either the left or right side of the machine tool, it also supports overhanging specifications that are extended to the left or right. can.

Conventionally, a cover has been individually manufactured according to the specifications of the work delivery position of the loader device, but the present invention has the cover structure of the loader device according to claim 1, and is provided on the front surface of the main body of the machine tool. It has a main body front cover, a front cover that covers the front side of the traveling rail portion that projects to the left or right side of the main body portion of the machine tool, and an L side cover and an R side cover that cover the left and right sides of the traveling rail portion. However, the front cover is characterized in that both the L side cover and the R side cover can be attached.
In this case, L mounting portions and R mounting portions are provided on the left and right sides of the front cover or the main body portion, and the L mounting portion can be mounted on both the front cover and the L side cover. It is preferable that both the front cover and the L side cover can be attached.

By using the loader device and the cover structure thereof according to the present invention, it is possible to start manufacturing a machine tool before the delivery specifications of the work on the production line on the user side are determined.
Moreover, even if the specifications on the user side are changed, it is easy to change the work delivery position at the site.

An example of a loader device and a cover structure thereof according to the present invention is shown. The traveling rail portion of the loader device is extended to the right side of the main body portion of the machine tool, and the assembled state is shown in an overhanging state.
