Abstract
Description
【発明の詳細な説明】 〔発明の技術分野〕 本発明は縦形の移動テーブル装置に関する。[Detailed description of the invention] [Technical field of invention] The present invention relates to a vertical moving table device.
従来縦形移動テーブル装置において重力補償を行なう場
合は、第3図に示すようにローラ44の左右に移動テー
ブル11とその重量に相当するカウンターウェイト12
を鋼製ベルト45で吊下げて行なっている。When performing gravity compensation in a conventional vertical movable table device, as shown in FIG.
This is done by suspending it with a steel belt 45.
しかしこの方式では、駆動モータ17によって、ガイド
43に沿って動く移動テーブル11を、急加速。However, in this method, the movable table 11 that moves along the guide 43 is rapidly accelerated by the drive motor 17.
急停止の駆動をおこなった後短時間に高精度な位置決め
をすることが出来ないという欠点を有していた。第4図

が出来ないのである。This has the disadvantage that highly accurate positioning cannot be performed in a short period of time after driving for a sudden stop. This will be explained in a simulated manner with reference to FIG. (A) Move table 11
When the steel belt 45 rapidly accelerates and rises, the steel belt 45 floats up from the roller 44, and then the counterweight 12 rises as shown in (B).
Since the moving table 11 is lowered, the moving table 11 is slightly pulled up due to this effect, and it becomes necessary to adjust the moving table 11 again, making it impossible to complete positioning in a short time.
本発明は上述した従来装置の欠点を改良したもので、急

本発明は、縦形の移動テーブルとカウンターウェイトを

な、繰り返し曲げによる彼方寿命を考慮する必要がなく
、長寿命も保証される。The present invention connects a moving table and a counterweight to feed screws for forward rotation and reverse rotation configured on the same axis, so that when the moving table is moved upward, the counterweight moves downward. When the counterweight is moved downward, the counterweight is moved upward to compensate for the gravity of the moving table, and since the connection is rigid, highly accurate and high-speed positioning is possible in a short time. In addition, there is no need to consider the long life due to repeated bending, which is the case when hanging with a rigid belt, and a long life is guaranteed.
また、移動テーブル部とカウンタウェイト部を同軸上に
構成しであるため、装置の設置面積が小さくてすむ。Furthermore, since the movable table section and the counterweight section are arranged coaxially, the installation area of the apparatus can be small.
第1図に本発明の一実施例を示す。 FIG. 1 shows an embodiment of the present invention.

を下降させようとする。The counterweight 12 is attached to a feed screw 14 whose feeding direction is opposite to that of the feed screw 13. Feed screw 13
.. 14 are connected and configured on the same axis and supported by a bearing 17. In this device, a moving table 1
The moving table 11 is moved by the drive motor 16 in order to raise the table 1.
When the feed screw 13 is rotated, the feed screw 14 on the coaxial counterweight 12 side rotates in the same direction as the feed screw 13. However, since the feed screw 14 is threaded in the opposite direction to the feed screw 13, the counterweight 12
try to lower it.

。(When the drive motor 16 rotates the feed screw 13 of the movable table 11 in order to lower the movable table 11, the counterweight 12 tries to rise.) This compensates for the gravity of the movable table 11, and Since the screws 13 and 14 have a rigid structure, they operate reliably, making it possible to position the movable table 11 with high precision and in a short time, while ensuring a long service life.
正転、逆転用の送りネジを一本の同一軸上に構成したが
、第2図のように正転、逆転用の送)ネジを別々の軸に
して、継手15で連結しても同様の効果が得られる。Although the feed screws for forward rotation and reverse rotation are configured on the same shaft, the same effect can be achieved even if the feed screws for forward rotation and reverse rotation are made into separate shafts and connected with the joint 15 as shown in Fig. 2. The effect of this can be obtained.
