no. 1 Embodiment

[0016] Refer below Figure 1 ~ Figure 3 A first embodiment in which the present invention is applied to a tool changing device comprising a turret-type tray will be described. In addition, the structure of the tool changer in this embodiment is the same as that disclosed in Japanese Patent Publication No. 7-80109, for example, and only the main parts related to the present invention will be described below.

[0017] FIG. 2( a ) shows a perspective view in which the tool pallet (conveying unit) 1 incorporated in the tool changing device is taken out. The tool tray 1 is mounted on the outer peripheral portion of a substantially disc-shaped tray base 2, and a plurality of clamp arms 3 are formed in a radial shape. As shown in FIG. 4, at the front end of the clamp arm 3, in order to clamp the upper end side of the tool holder (transport object) 4 with the tool installed on the lower end side, the holding part 5 is formed in a U-shape. On both sides of the front end, support pins...

no. 2 Embodiment

[0044] 4 to 6 show the second embodiment of the present invention, the same parts as the first embodiment are given the same symbols, and their descriptions are omitted, and only the different parts will be described below. In the second embodiment, the main CPU 11 of the numerical control device 10 also considers the distribution state of the tools 4 arranged on the tool pallet 1 to determine the maximum rotational angular acceleration Amax.

[0045] FIG. 4 illustrates the influence of the rotation of the tray base 2 on the distribution balance of the tools 4 . The bottom in Fig. 4 becomes the direction of gravity action. As shown in Fig. 4(a), on the tray base 2, if the tool 4 at the position (A) is moved to the position (B) for tool exchange, the vicinity of the position (A) becomes the point of rotation. In the acceleration area, the vicinity of position (B) becomes the deceleration area of ​​the rotary motion. Between the two becomes a constant velocity region.

Abstract

The present invention discloses a conveying device which comprises a conveying part driven by an electromotor and driving objects to be conveyed to rotate to be conveyed to a preceptive position, an inertia presumption mechanism used for presumption of the inertia of the conveying part, and an acceleration determining mechanism used for determining the most rotary angular acceleration of the conveying part according to putative inertia of the inertia presumption mechanism and the most output torque moment of the electromotor.

Description

technical field [0001] The present invention relates to a conveying device having a conveying unit configured to convey an object to be conveyed by rotating it, and a conveying acceleration setting method of the conveying device. Background technique [0002] Japanese Patent Application Laid-Open No. 3-60941 discloses a technique for appropriately changing the conveying speed according to the weight moment of the tool in an apparatus for conveying a tool used in a machine tool by rotating it. [0003] However, since the weight moment has an influence on the acceleration, when the conveyance speed is determined based on the weight moment, the optimum conveyance speed may not always be obtained even if it is reasonable to some extent. [0004] Also, if the conveying speed is set to a high speed, rather than maintaining the speed, it is better to say that the acceleration to reach the speed is obtained, so a larger output torque of the motor is required (refer to Figure 7 ). ...
