Loading device for loading bars for machining in machine tools

Abstract

The loading device is arranged a rod (1a), which is passed from an initial position into an end position, and the rod is supplied from the end position into a machine tool. A support section (21) is provided for storing the loading device with the rod, which lies in the initial position on the support section. A transport unit (3) is provided, which is arranged to transport the rod in a downward movement corresponding to the gravity along a downward inclined guide section (41b).

Description

technical field [0001] The invention relates to a loading device for loading a bar for processing in a machine tool, wherein the loading device is adapted to move the bar from a starting position to an end position and to feed the bar from the end position to the machine tool, which comprising a laying part for supplying the loading device with at least one bar placed on the laying part in the starting position and a movable transporting device for transporting the bar from the starting position to the end position . [0002] In addition, the invention relates to a system comprising a machine tool for processing bars and a loading device for loading bars for processing in the machine tool, wherein the loading device is adapted to load the bars from a starting The position is moved to the end position, and the bar is fed from the end position to the machine tool, which comprises a laying part and a movable transport device, the laying part is used to supply the loading device ...

AI Technical Summary

Problems solved by technology

However, its main disadvantage is that, when the bar to be transported has come out of contact with the holding element 17 during the upward movement of the lifting element 22, it will use its gravity to roll down the downwardly sloping surface 23 and hit the lifting element 22 The holding area of ​​24

[0011] Due to the impact of the bar after rolling down on the surface 23 of the lifting element 22, there is the main disadvantage that the entire loading device connected to the machine tool is subjected to impacts or vibrations which, in addition to being transmitted to the loading device, also pass to the machine tool

As a result, machining operations on the machine are adversely affected

In the case of long-term use of the loading device, the components of the loading device or the machine tool must be damaged in this case

Also, during the load cycle, when collisions occur, such collisions can be extremely noisy

However, according to Figure 8B , a further disadvantage is that the size of the holding area 24 limits the cross-section of the bars that can be loaded, since bars with larger cross-sections may be transported to the holding bar due to the shocks that occur during the downward rolling motion. outside area 24

[0014] In this case, however, the loading device disclosed according to EP1029619A1 has the main disadvantage that the device can only be adapted to bars of different bar cross-sections with complex mechanisms

However, in addition, complex mechanisms are required to adapt the inclination and shape of the stop fingers to the cross-section of the bar
