Abstract

PURPOSE:To prevent electrical parts of a robot from being thermally affected by inserting hard heat insulating materials between the terminal movable member of the robot and the base member of a ladle for ladling a molten metal attached as an end effecter to the robot. CONSTITUTION:The robot for casting is vertically and pivotally supported with a swiveling base 2 on a base plate 1, is horizontally and pivotally supported with the 1st arm 3 on the base 2, is pivotally supported with the 2nd arm 4 to the top end of the arm 3, is horizontally and pivotally supported with the 3rd arm 5 to the top end of the arm 4 and is supported with a turning body 6 as the terminal movable member to the top end of the arm 5 by the shaft intersecting orthogonally with the horizontal shaft. The end effecter, i.e., the ladle 7 for ladling the molten metal is attached to the body 6. The hard heat insulating materials 15, 18 are inserted between the body 6 and the base member 13 of the ladle 7. The transfer of the heat to the electrical parts contained in the body 6 is thus decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a casting robot for pouring hot water into a mold.

[Prior art and problems]

Conventionally, in the die-casting department, using link mechanisms etc.
The process of scooping hot water from the pot and pouring the hot water through the pouring spout is performed in a sequential manner. By the way, in the above-mentioned device, the power source for operating the link mechanism and the ladle attached to its tip is remote from the base of the link mechanism, that is, the heat source of the pot or the ladle that scoops hot water. It is located somewhere. Therefore, there is no need for electrical components such as the power source to be affected by heat and cause problems.

However, if a well-known industrial robot is used to provide versatility in the movement of the ladle, electric components such as a power source and a position detector for operating the ladle are located near the ladle, which causes heat generation. affected and unbearable to use.

[Purpose of the invention]

This invention was made in view of the above-mentioned circumstances, and aims to provide a robot for subsequent casting in which the electrical components of the robot are not affected by heat.

[Detailed description of the invention]

The present invention is a casting robot in which a hard heat insulating material is inserted between the movable end member of the robot and the base member of the ladle.

〔Example〕

RB is a casting robot, and in this embodiment, it is an articulated robot with five degrees of freedom. That is, a swivel base 2 is vertically supported on the base 1, a first arm 3 is horizontally supported on the swivel base 2, and
Further, a second arm 4 is horizontally supported at the tip of the arm 3, a third arm 5 is horizontally supported at the tip of the arm 4, and a rotating body 6 as a movable end member is mounted at the tip of the arm 5. It is supported by an axis perpendicular to the horizontal axis. An end effector, that is, a two dollar 7 for scooping hot water is attached to this rotating body 6.

It should be noted that a material with high heat reflectivity is attached to the outer surface of this robot RB (particularly the outer surface of the arms 3.4.5).

The structure around the rotating body 6 and the ladle 7 will be explained below.

Reference numeral 11 denotes a flange fastened to the rotating body 6 with bolts 12.

Reference numeral 13 designates a 7 flange (base member) in which the ladle 7 is fixed to the bin 14.

Reference numeral 15 denotes a hard heat insulating material inserted between both 7 flange 11 and 13, and a hard heat insulating material 18 is also inserted between the off flange 11 and the nut 17 which are fixed by bolts 16 and nuts 17.

Note that the heat insulating material 18 may be inserted between the flange 13 and the head of the bolt 16.

19 and 20 are known sensors that are both attached to the 7-lunge 13 and are used to detect the level of the hot water being melted in the pot. These sensors 19.20 are made of thermal, electrically insulating material 21
via 7 langes 18, sandwiched between member 22.2B,
It is fixed with bolts 24.

〔Effect of the invention〕

Since this invention is as described above, even if the ladle 7 is placed in the pot and hot water is poured, the heat of the hot water is difficult to be transmitted to the rotating body 6 due to the heat insulating materials 15 and 18. Therefore, even if the power source of the rotating body 6 and electrical components such as the position detector are built into the arm 5 and the distance from the ladle 7 is short, there is no effect of heat and there is no problem in controlling the position of the robot RB. .
