Description

本発明は交差するXパンタを開閉する事でテーブルを上下駆動するボールねじ駆動型テーブルリフトに関する。  The present invention relates to a ball screw drive type table lift that drives a table up and down by opening and closing crossing X punters.

近年ボールねじを利用したボールねじ駆動型テーブルリフトの需要が増えてきている。(特許文献1、特許文献2参照。)  In recent years, the demand for ball screw driven table lifts using ball screws has increased. (See Patent Document 1 and Patent Document 2.)

以下図1〜図3により従来のテーブルリフトについて説明する。図1は従来の油圧テーブルリフトの側面図である。図で油圧シリンダーがその伸縮により直接Xパンタを開閉してテーブルを上下駆動している。  A conventional table lift will be described below with reference to FIGS. FIG. 1 is a side view of a conventional hydraulic table lift. In the figure, the hydraulic cylinder moves the table up and down by directly opening and closing the X-panter by its expansion and contraction.

図2は特許文献1の電動リフト側面図で、内アームに回転可能に連結され、他端に設けられたガイドローラーが外アームに設けられ、パンタの交差点方向に設けられた長穴に沿って動く中間アームを電動シリンダーで駆動することで、交差するパンタアームの交差角を変え、テーブルを上下駆動している。図3は特許文献1の平面図で外アーム、内アーム、中間アーム、電動シリンダー等の配置状態が分かる。  FIG. 2 is a side view of the electric lift of Patent Document 1, which is rotatably connected to the inner arm, a guide roller provided at the other end is provided on the outer arm, and along an elongated hole provided in the direction of the intersection of the panta. By driving the moving intermediate arm with an electric cylinder, the crossing angle of the intersecting punter arms is changed and the table is driven up and down. FIG. 3 is a plan view of Patent Document 1 showing the arrangement of the outer arm, inner arm, intermediate arm, electric cylinder, and the like.

図4は特許文献2の平面図で外アーム、内アーム、中間アーム、電動シリンダー等の配置状態が分かる。  FIG. 4 is a plan view of Patent Document 2 showing the arrangement of the outer arm, inner arm, intermediate arm, electric cylinder, and the like.

特許番号第2591598号Patent No. 2591598 公開特許番号2003−155195Published Patent No. 2003-155195

第1に従来のテーブルリフトはテーブルが下限にある時の移動速度は大きく、上限に近ずくに従い速度が遅くなり、その比率は最大2:1に達することもある。  First, the conventional table lift has a high moving speed when the table is at the lower limit, and the speed decreases as the table approaches the upper limit, and the ratio may reach 2: 1 at the maximum.

第2に、従来のテーブルリフトは偏荷重に弱く偏荷重が働くと、その方向に撓む問題があった。  Secondly, the conventional table lift has a problem of being deflected in the direction when the load is weak against the uneven load.

第3に、従来から横方向(パンタアームに直交する方向)の寸法の小さいテーブルリフトの需要があったが、従来の構造ではその実現は難しかった。  Thirdly, there has been a demand for table lifts having a small size in the lateral direction (direction perpendicular to the panta arm), but it has been difficult to realize with conventional structures.

問題を解決するための手段Means to solve the problem

本発明の第1、第2の課題解決手段は1対の外アームに設けられた回転軸A(中心点a)と、その回転軸に設けられ、それを正逆転駆動するブラケットに設けられた支点B(中心点b)と、回転軸(A)の両端にテーブルリフトの中心面に対称に設けられたブラケットに設けられた2個のコロC(中心点c)と、一対の内アームに設けられ2個のコロを受けるカムよりなるテーブルリフトでa−b−cで固定の三角形を形成し、頂角b−a−cを60°近くにする事で下限から上限に至るまで速度変化が小さい状態にする事ができる。この角度は通常60°近くにすれば速度変化は30%程度に収まる。また、この角度は0°〜60°位が望ましい。平面図6(テーブル寸法:700×1000mm)、側面図7(最低高さ:180mm)のテーブルリフトで試算した結果を図5に示している。図5参照。    The first and second problem solving means of the present invention are provided on a rotating shaft A (center point a) provided on a pair of outer arms, and on a bracket provided on the rotating shaft to drive it forward and backward. A fulcrum B (center point b), two rollers C (center point c) provided on brackets provided symmetrically with the center plane of the table lift at both ends of the rotating shaft (A), and a pair of inner arms A table lift consisting of a cam that receives two rollers and forms a fixed triangle with abc, and changes the speed from the lower limit to the upper limit by making the apex angle bac close to 60 ° Can be made small. If this angle is normally close to 60 °, the speed change will be about 30%. Further, this angle is preferably about 0 ° to 60 °. FIG. 5 shows the result of trial calculation using the table lift shown in the plan view 6 (table size: 700 × 1000 mm) and the side view 7 (minimum height: 180 mm). See FIG.

また、この構造で,回転軸Aの両端に設けられたコロはその軸心から等距離、同位相に設けられているので両内アームはカムを介して同期して駆動される。この結果、横方向の力、又は偏荷重が加わっても左右のテーブル高さも等しくなり、結果的に横荷重、または偏荷重に強くなる。  Also, with this structure, the rollers provided at both ends of the rotary shaft A are provided at the same distance from the axis and in the same phase, so that both inner arms are driven in synchronization via the cam. As a result, even if a lateral force or an offset load is applied, the left and right table heights are also equal, and as a result, the lateral load or the offset load becomes stronger.

また第3の課題解決手段は駆動減速モーターとそれにカップリングにより直結されたボールねじ等駆動系をテーブルリフトの中心面に配し、請求項1の発明で回転軸の両端に設けるコロ用ブラッケト(9)と、2個のコロを正逆転駆動するブラケット(10)を一体化にする事で重複するスペースを省く事が出来、横巾の小さいテーブルリフトの製作が可能になる。図6、図9を比較すればこの事が理解できる。According to a third aspect of the present invention, there is provided a roller bracket for a roller provided on both ends of a rotary shaft according to the invention of claim 1 by arranging a drive system such as a ball screw screw directly coupled by a drive speed reduction motor and a coupling to the center plane of the table lift. 9) and the bracket (10) for driving the two rollers forward / reversely can be integrated to eliminate an overlapping space, and a table lift with a small width can be manufactured. This can be understood by comparing FIG. 6 and FIG.

発明の効果The invention's effect

上記第1、第2の課題解決手段による作用効果は次のとおりである。すなわち、請求項1に示す頂角b−a−cを60°程度にする事で上昇、下降の速度変化は小さくなり速度変化率{(最大速度―最小速度)/最大速度}は3割程度に収まる。速度の変化が少ない事は作業性、安全性の観点から望ましく、製作面でもテーブルリフトをコンパクトに製作出来る。  The operational effects of the first and second problem solving means are as follows. That is, when the apex angle bac shown in claim 1 is set to about 60 °, the speed change of ascending and descending becomes smaller and the speed change rate {(maximum speed−minimum speed) / maximum speed} is about 30% Fits in. A small change in speed is desirable from the viewpoint of workability and safety, and the table lift can be made compact in terms of production.

また、所要動力は荷重と速度の積に比例する事から速度変化が大きいと所要動力も大きくなる。従って速度変化が小さくなることは使用モーターの出力を小さく、また、フレームの構成部材も小さく出来る。  Further, since the required power is proportional to the product of the load and the speed, the required power increases when the speed change is large. Therefore, the smaller the speed change, the smaller the output of the motor used, and the smaller the components of the frame.

また,回転軸Aの両端に設けられたコロはその軸心から等距離、同位相に設けられているので両内アームは同期して駆動される。更に、回転軸Aの断面2次モーメントを充分大きくしておけば両端のブラケットにかかる力に差があっても、両ブラケットの動きに差は生じない。この結果偏荷重があっても左右のテーブル高さも等しくなり、偏荷重に対して強いテーブルリフトを作る事が可能になった。  Further, the rollers provided at both ends of the rotation axis A are provided at the same distance from the axis and in the same phase, so that both inner arms are driven in synchronization. Further, if the moment of inertia of the rotary shaft A is sufficiently large, even if there is a difference in the force applied to the brackets at both ends, there will be no difference in the movement of both brackets. As a result, the left and right table heights are equal even when there is an unbalanced load, making it possible to create a table lift that is strong against unbalanced loads.

上記第2の課題解決手段により従来より100mm程度巾の小さいテーブルリフトが製作可能になり、スペース上従来使用不可能であった場所にも使用出来る様になった。  The second problem solving means makes it possible to manufacture a table lift having a width of about 100 mm smaller than that of the prior art, and it can be used in places where it has been impossible to use in the past due to space.

以下本発明の実施の形態として第1の実施例及び第2の実施例を図6〜図8に基づいて説明する。  Hereinafter, a first example and a second example will be described as embodiments of the present invention with reference to FIGS.

図5に実施例の電動テーブルリフトの平面図を、図6に実施例の電動テーブルリフトの側面図を示している。図で減速モーター1はカップリング2をへてボールねじ4を回転駆動している。ロット8には減速モーター1、スラスト軸受箱5が取り付けてあり、ボールなっと7に生じる力はボールねじ4、スラスト軸受箱5、ロット8を経由して内アームの端軸6に伝えられる。
ボールなっと7はボールねじ4の回転によりボールねじ4の軸方向に駆動され、ボールなっと7が取り付けてある取り付け箱13に取り付けてあるピンBを経由しブラッケト9で回転軸Aを回転駆動している。
FIG. 5 is a plan view of the electric table lift of the embodiment, and FIG. 6 is a side view of the electric table lift of the embodiment. In the figure, the reduction motor 1 rotates the ball screw 4 through the coupling 2. The lot 8 is provided with a reduction motor 1 and a thrust bearing box 5, and the force generated in the ball 7 is transmitted to the end shaft 6 of the inner arm via the ball screw 4, the thrust bearing box 5 and the lot 8.
The ball 7 is driven in the axial direction of the ball screw 4 by the rotation of the ball screw 4, and the rotary shaft A is rotationally driven by the bracket 9 via the pin B attached to the mounting box 13 to which the ball 7 is attached. is doing.

このとき回転軸Aの中心点a,ボールなっとピンの中心点b、持ち上げコロCの中心点cは固定の三角形を形成している。ボールなっと7がボールなっとピンB、ブラッケト9を経て回転軸Aを回転駆動する。この結果持ち上げコロCは回転軸Aに取り付けられたブラケット10に取り付けられ、内アーム15に設けられたカム14を持ち上げ、内アームは内アーム端軸6を中心に揺動する。  At this time, the center point a of the rotation axis A, the center point b of the pin, and the center point c of the lifting roller C form a fixed triangle. When the ball becomes 7 and the ball becomes, the rotary shaft A is driven to rotate through the pin B and the bracket 9. As a result, the lifting roller C is attached to the bracket 10 attached to the rotating shaft A, lifts the cam 14 provided on the inner arm 15, and the inner arm swings around the inner arm end shaft 6.

一般のリフトでは内、外アームが、そのセンターピン7を中心に開閉駆動されるが請求項1の発明では内アームは内アーム端軸6を中心に持ち上げコロCで駆動され、内アーム端軸6の中心から持ち上げコロC迄の長さが長い為(約3倍)内アームの回転速度も遅くなる。この事がテーブルリフトの上下速度の変動が小さくなる原因である。  In a general lift, the inner and outer arms are driven to open and close around the center pin 7. However, in the invention of claim 1, the inner arm is driven by the roller C around the inner arm end shaft 6, and the inner arm end shaft is driven. Since the length from the center of 6 to the lifting roller C is long (about 3 times), the rotation speed of the inner arm also becomes slow. This is the reason why the fluctuation in the vertical speed of the table lift is reduced.

請求項2の発明ではテーブルの横巾を小さくするため、減速モーター1とボールねじ4を直線上に配し、ボールねじ4に生じる力を減速モーター1と内アーム15の間に設けられたロット8を経由して内アーム端軸6に伝えている。同時にコロCの取りつけブラッケト10と、コロCをボールねじ4の取り付ブロック13の取り付けブラッケト9を一体化し、重複したスペースを無くした。この事で横幅を従来のテーブルのより100mm程度小さくする事が出来た。  In the invention of claim 2, in order to reduce the width of the table, the reduction motor 1 and the ball screw 4 are arranged on a straight line, and the force generated in the ball screw 4 is provided between the reduction motor 1 and the inner arm 15. 8 is transmitted to the inner arm end shaft 6 via 8. At the same time, the mounting bracket 10 of the roller C and the mounting bracket 9 of the mounting block 13 of the ball screw 4 were integrated with the roller C to eliminate the overlapping space. This allowed the width to be reduced by about 100 mm compared to the conventional table.

以上の様に請求項1〜請求項2の発明を実施すれば、横荷重に強く、昇降速度の変化の小さいテーブルリフトが可能になる。また、従来より横巾の小さいテーブルリフトが製作可能になる。  As described above, when the inventions according to claims 1 and 2 are implemented, a table lift that is resistant to a lateral load and has a small change in lifting speed can be realized. In addition, a table lift having a smaller width than the conventional one can be manufactured.

上下速度変化が小さく、横荷重に強いテーブルリフトは精密動作が必要なIT産業等の自動化ライン等に需要がみこまれる。  Demand for table lifts, which have a small vertical speed change and are resistant to lateral loads, can be found in automated lines in the IT industry that require precise operation.

また、横巾を小さいテーブルリフトは従来から需要が大きかったので、従来より更に100mm程小さい物が製作可能になり、各方面で使用されるものと思われる。  In addition, since a table lift with a small width has been in great demand, it is possible to manufacture a product that is smaller by about 100 mm than before, and it is expected that it will be used in various directions.
