(第1實施方式)
(first embodiment)
以下針對作為動力機構的一種之可動體移動裝置中所使用的往復驅動
用鏈條的第1實施方式，參照圖示進行說明。
The following is for the reciprocating drive used in the movable body moving device as a kind of power mechanism
The first embodiment of the chain will be described with reference to the drawings.
如圖1所示，可動體移動裝置11具備作為能夠沿著長度方向往復移動的往復驅動用鏈條之一例的嚙合鏈條12、及能夠將往復移動的嚙合鏈條12以自由進出的方式收容的收容部13。嚙合鏈條12具有能夠互相嚙合的一對鏈條構件，也就是第1鏈條構件14及第2鏈條構件15。第1鏈條構件14及第2鏈條構件15分別具有串聯配置的多個鏈條元件16。第1鏈條構件14及第2鏈條構件15分別構成為：直列方向上相鄰的鏈條元件16彼此依序地連結而形成長條狀。其中，位於第1鏈條構件14的頂端部的鏈條元件16與位於第2鏈條構件15的頂端部的鏈條元件16之間通過接頭部17連結。第1鏈條構件14及第2鏈條構件15的頂端部在圖1中對應於上端部。此外，接頭部17安裝有可動體18。可動體18構成為：於支撐例如升降動作的頂板或開閉動作的門等機能性構件的狀態下與嚙合鏈條12一起往復移動。
As shown in FIG. 1 , the movable body moving device 11 includes an engagement chain 12 as an example of a reciprocating driving chain capable of reciprocating along the longitudinal direction, and a housing portion that accommodates the reciprocating engagement chain 12 so that it can be freely moved in and out. 13. The meshing chain 12 has a pair of chain members capable of meshing with each other, that is, a first chain member 14 and a second chain member 15 . The first chain member 14 and the second chain member 15 each have a plurality of chain elements 16 arranged in series. The 1st chain member 14 and the 2nd chain member 15 are each comprised so that the chain element 16 adjacent to the serial direction may be connected sequentially, and shall form an elongate shape. Among them, the chain element 16 located at the distal end of the first chain member 14 and the chain element 16 located at the distal end of the second chain member 15 are connected by a joint portion 17 . The tip end portions of the first chain member 14 and the second chain member 15 correspond to upper end portions in FIG. 1 . Furthermore, a movable body 18 is attached to the joint portion 17 . The movable body 18 is configured to reciprocate together with the meshing chain 12 while supporting a functional member such as a ceiling that moves up and down or a door that moves up and down.
嚙合鏈條12通過第1鏈條構件14及第2鏈條構件15於行進方向各別移動藉此相互嚙合而一體化成直棒狀。行進方向對應於長度方向中朝向第1鏈條構件14及第2鏈條構件15的頂端的方向。嚙合鏈條12通過從第1鏈條構件14與第2鏈條構件15相互嚙合而一體化成直棒狀的嚙合狀態往與行進方向相反的後退方向各自移動，從而相互脫離嚙合而分岐。此外，當第1鏈條構件14及第2鏈條構件15往後退方向移動時，嚙合鏈條12於其長度方向從基端往頂端側相連的既定長度的部分會被收容至收容部13內。另一方面，當第1鏈條構件14及第2鏈條構件15往行進方向移動時，嚙合鏈條12於其長度方向從頂端往基端側相連的
既定長度的部分會露出於收容部13外。
The meshing chain 12 is integrated into a straight bar shape by meshing with each other by moving the 1st chain member 14 and the 2nd chain member 15 in a traveling direction respectively. The traveling direction corresponds to the direction toward the tips of the first chain member 14 and the second chain member 15 in the longitudinal direction. The meshing chains 12 move from the meshing state where the first chain member 14 and the second chain member 15 are meshed with each other and are integrated into a straight rod shape to the backward direction opposite to the advancing direction, thereby disengaging from each other and diverging. In addition, when the first chain member 14 and the second chain member 15 move in the backward direction, a predetermined length of the engaging chain 12 connected from the proximal end to the distal end in the longitudinal direction is accommodated in the accommodating portion 13 . On the other hand, when the first chain member 14 and the second chain member 15 move toward the advancing direction, the meshing chain 12 is connected from the top end to the base end side in the longitudinal direction.
A portion of a predetermined length is exposed outside the housing portion 13 .
其中，以下的記載中，將安裝於接頭部17的可動體18進行移動時的嚙合鏈條12的往復移動方向設為Z。此時，將圖1中作為向上方向之嚙合鏈條12的行進方向設為Z1，將圖1中作為向下方向之嚙合鏈條12的後退方向設為Z2。往復移動方向Z與嚙合鏈條12的長度方向一致。此外，與往復移動方向Z垂直的方向當中，將從第1鏈條構件14及第2鏈條構件15相互嚙合而一體化的嚙合狀態往後退方向Z2移動所伴隨的相互脫離嚙合而分岐的方向設為分岐方向X。此外，將與往復移動方向Z及分岐方向X之兩者垂直的方向設為深度方向Y。深度方向Y與鏈條元件16的寬度方向一致。
However, in the following description, the reciprocating movement direction of the meshing chain 12 when the movable body 18 attached to the joint part 17 moves is set to Z. As shown in FIG. At this time, the advancing direction of the meshing chain 12 which is the upward direction in FIG. 1 is Z1, and the backward direction of the meshing chain 12 which is the downward direction in FIG. 1 is Z2. The reciprocating direction Z coincides with the length direction of the engaging chain 12 . In addition, among the directions perpendicular to the reciprocating direction Z, the direction in which the first chain member 14 and the second chain member 15 are meshed and integrated with each other and the meshed state is moved to the backward direction Z2 accompanied by mutual disengagement and branching is defined as Bifurcation direction X. In addition, let the direction perpendicular to both the reciprocating direction Z and the branching direction X be the depth direction Y. The depth direction Y coincides with the width direction of the chain element 16 .
如圖1所示，收容部13構成為：能夠收容嚙合鏈條12在長度方向的一部分。收容部13內的上部中分岐方向X的中央部設有鏈輪19。藉由從例如電動機等驅動源賦予旋轉動力，鏈輪19會以沿著深度方向Y的軸為旋轉中心往正反兩方向旋轉驅動。本實施方式中，鏈輪19配置為：齒尖從第2鏈條構件15所在之側於分岐方向X對嚙合鏈條12中第1鏈條構件14與第2鏈條構件15互相嚙合而成為直棒狀的部分進行嚙合。然後，隨著鏈輪19的旋轉驅動，藉由嚙合鏈條12沿著往復移動方向Z往復移動，從而使可動體18向往復移動方向Z移動。
As shown in FIG. 1, the accommodation part 13 is comprised so that it can accommodate a part of the meshing chain 12 in the longitudinal direction. A sprocket 19 is provided at the central part in the branching direction X in the upper part of the receiving part 13 . By applying rotational power from a drive source such as a motor, the sprocket 19 is rotationally driven in both the forward and reverse directions around the axis along the depth direction Y as the rotation center. In this embodiment, the sprocket 19 is arranged such that the tooth tip is engaged with the chain 12 in the bifurcated direction X from the side where the second chain member 15 is located. Partially engaged. Then, the movable body 18 moves in the reciprocating direction Z by the engaging chain 12 reciprocating in the reciprocating direction Z as the sprocket 19 is rotationally driven.
此外，收容部13具備呈大致相同的矩形狀的前板20及後板21。前板20及後板21於深度方向Y隔著既定的間隔而相對向。前板20及後板21被沿著深度方向Y未圖示的連結體而連結著。嚙合鏈條12及鏈輪19配置於前板20與後板21之間的空間區域。前板20及後板21
的內側面設有一對彎曲的誘導溝22，其往分岐方向X的兩側分離。一對誘導溝22對從嚙合狀態分岐的第1鏈條構件14及第2鏈條構件15進行誘導，使其以曲線的方式移動。
Moreover, the housing part 13 is provided with the front board 20 and the rear board 21 which are substantially the same rectangular shape. The front plate 20 and the rear plate 21 face each other at a predetermined interval in the depth direction Y. As shown in FIG. The front plate 20 and the rear plate 21 are connected along the depth direction Y by a not-shown connecting body. The engaging chain 12 and the sprocket 19 are disposed in a space area between the front plate 20 and the rear plate 21 . Front plate 20 and rear plate 21
A pair of curved induction grooves 22 are provided on the inner side of the inner surface, which are separated to both sides of the branching direction X. The pair of guiding grooves 22 guide the first chain member 14 and the second chain member 15 diverging from the meshed state to move in a curved line.
接著，針對鏈條元件16進行說明。
Next, the chain element 16 will be described.
如圖2及圖3所示，鏈條元件16具備既定長度呈帶板狀的撓曲部23、撓曲部23中位於長度方向的第1端側的塊狀的第1連結部24、及撓曲部23中位於長度方向的第2端側的塊狀的第2連結部25。其中，在以下既定的構件的說明中使用「第1端側」「第2端側」這種表現時，意思是表示在與該構件一起構成鏈條元件16的撓曲部23沿著長度方向的方向上該構件的「第1端側」「第2端側」。
As shown in FIGS. 2 and 3 , the chain element 16 has a strip-shaped flexible portion 23 with a predetermined length, a block-shaped first connecting portion 24 located at the first end side in the longitudinal direction of the flexible portion 23 , and a flexible portion 23 . A block-shaped second connecting portion 25 located on the second end side in the longitudinal direction of the curved portion 23 . Here, when expressions such as "first end side" and "second end side" are used in the description of the following predetermined members, it means that the flexure portion 23 constituting the chain element 16 together with the member is in the longitudinal direction. The "first end side" and "second end side" of the member in the direction.
鏈條元件16中，撓曲部23是由一對能夠彈性變形的帶板狀的構件所構成。帶板狀的構件的板厚僅較形成於前板20及後板21的內側面的誘導溝22的溝寬度薄一些。當鏈條元件16在收容部13內移動時，撓曲部23會在沿著其長邊方向的側邊部於誘導溝22上滑動。因此，當撓曲部23在誘導溝22的曲線部分滑行移動時，會沿著其誘導溝22的線部分而彎曲。
In the chain element 16, the flexure 23 is constituted by a pair of elastically deformable strip-shaped members. The thickness of the strip-shaped member is only slightly thinner than the groove width of the induction groove 22 formed on the inner surface of the front plate 20 and the rear plate 21 . When the chain element 16 moves in the receiving portion 13 , the flexure portion 23 slides on the guiding groove 22 at the side portion along the longitudinal direction thereof. Therefore, when the flexure 23 slides and moves on the curved portion of the induction groove 22 , it will bend along the line portion of the induction groove 22 .
此外，鏈條元件16中，第1連結部24構成為：從深度方向Y觀看時，形成外形的外表面的一部分呈連續的段差面。另一方面，第2連結部25形成為相對於第1連結部24更大的塊狀。第2連結部25的一部分形成有缺口狀的卡合部26。缺口狀的卡合部26具有內面，其由與第1連結部24的上述段差面對應的段差面構成。詳細而言，鏈條元件16中的第2連結部25的卡合部26能夠在與該鏈條元件16於直列方向上
相鄰的其他鏈條元件16中的第1連結部24其外表面的一部分嵌合的狀態下卡合。其中，缺口狀的卡合部26中的第2端側的開口緣的部分構成爪狀的卡止部27。爪狀的卡止部27能夠對在外表面的一部分嵌合於其卡合部26的內面而卡合的狀態下的其他鏈條元件16的第1連結部24從第2端側進行卡止。
Moreover, in the chain element 16, the 1st connection part 24 is comprised so that when viewed from the depth direction Y, a part of the outer surface which forms an outer shape becomes a continuous step surface. On the other hand, the second connecting portion 25 is formed in a larger block shape than the first connecting portion 24 . A notch-shaped engagement portion 26 is formed in a part of the second connection portion 25 . The notch-shaped engagement portion 26 has an inner surface constituted by a stepped surface corresponding to the aforementioned stepped surface of the first coupling portion 24 . Specifically, the engaging portion 26 of the second connecting portion 25 in the chain element 16 can be aligned with the chain element 16 in the straight direction.
The first connecting portion 24 of another adjacent chain element 16 engages in a state where a part of the outer surface is fitted. Among them, the portion of the opening edge on the second end side of the notch-shaped engaging portion 26 constitutes a claw-shaped locking portion 27 . The claw-shaped locking portion 27 can lock the first connecting portion 24 of the other chain element 16 from the second end side in a state where a part of the outer surface is fitted and engaged with the inner surface of the engaging portion 26 .
鏈條元件16可為金屬製，本實施方式中是以耐摩耗性及自我潤滑性優異，常用來作為金屬的代替品的樹脂系的素材之工程塑膠為原材料而成形。一般而言，工程塑膠為耐熱性攝氏100度以上，強度50MPa以上，彎曲彈性率2.4GPa以上的素材。本實施方式的鏈條元件16是藉由作為工程塑膠之一例的聚縮醛(POM)，使撓曲部23、第1連結部24、及第2連結部25一體成形。因此，當與其長度方向交叉的方向之板厚方向發生彎曲應力時，鏈條元件16中的帶板狀的撓曲部23會往其彎曲應力作用的方向撓曲變形。
The chain element 16 may be made of metal, and in this embodiment, it is molded from engineering plastic, a resin-based material that has excellent wear resistance and self-lubricating properties and is often used as a substitute for metal. Generally speaking, engineering plastics are materials with heat resistance above 100 degrees Celsius, strength above 50MPa, and bending modulus above 2.4GPa. In the chain element 16 of the present embodiment, the flexure portion 23 , the first connection portion 24 , and the second connection portion 25 are integrally formed using polyacetal (POM), which is an example of engineering plastic. Therefore, when a bending stress occurs in the plate thickness direction intersecting with the longitudinal direction, the strip-shaped flexure portion 23 in the chain element 16 bends and deforms in the direction in which the bending stress acts.
如圖4及圖5所示，鏈條元件16具備第1分割體28及第2分割體29，其於與撓曲部23的短邊方向一致的深度方向Y分割成二個。第1分割體28及第2分割體29從其被分割的狀態通過於深度方向Y的接合而一體化。如圖4所示的第1分割體28具有呈帶板狀的撓曲部30、撓曲部30中位於第1端側的板片狀的第1連結部31、及撓曲部30中位於第2端側的板片狀的第2連結部32。同樣地，圖5所示的第2分割體29也具有呈帶板狀的撓曲部33、撓曲部33中位於第1端側的板片狀的第1連結部34、及撓曲部33中位於第2端側的板片狀的第2連結部35。
As shown in FIGS. 4 and 5 , the chain element 16 includes a first divided body 28 and a second divided body 29 which are divided into two in the depth direction Y which coincides with the short-side direction of the flexure 23 . The first divided body 28 and the second divided body 29 are integrated by joining in the depth direction Y from their divided state. The first divided body 28 shown in FIG. The plate-like second connecting portion 32 on the second end side. Similarly, the second split body 29 shown in FIG. 5 also has a strip-shaped flexure 33, a plate-shaped first connecting portion 34 located on the first end side of the flexure 33, and a flexure. 33 is a plate-shaped second connecting portion 35 located on the second end side.
首先，針對第1分割體28進行說明。
First, the first divided body 28 will be described.
如圖4所示，第1分割體28中，第1連結部31與第2連結部32為各自的板厚尺寸與沿著撓曲部30的短邊方向的寬度尺寸大致相同的板片。第1連結部31具有第1分割體28與第2分割體29接合時與第2分割體29對向的面。此外，其面內之中，沿著靠向第2連結部32的那一側，也就是第2端側的緣邊的區域形成有第1小***部36。此外，該第1小***部36中與第2分割體29對向的面形成有第1小凸部37。
As shown in FIG. 4 , in the first divided body 28 , the first connection portion 31 and the second connection portion 32 are plate pieces having substantially the same thickness dimension and width dimension along the short-side direction of the flexure portion 30 . The first connecting portion 31 has a surface facing the second split body 29 when the first split body 28 and the second split body 29 are joined.

Specifically, the first chain member 14 and the second chain member 15 form a first side surface 51 on the advancing direction Z1 side of each segment portion 50 and a second side surface 52 on the retreating direction Z2 side of the opposing segment portion 50 . In the state of being in contact with each other, they move back and forth in a straight line. In the segment portion 50 , the first side surface 51 on the traveling direction Z1 side is constituted by the side surface of the second connecting portion 25 on the traveling direction Z1 side. In addition, in the block portion 50, the second side surface 52 on the side in the retreat direction Z2 is formed by the surface where the side surface on the side in the retreat direction Z2 of the first connecting portion 24 and the side surface on the side in the retreat direction Z2 of the second connecting portion 25 meet. constitute.
段塊部50中行進方向Z1側的第1側面51及後退方向Z2側的第2側面52相對於往復移動方向Z並非為彼此垂直的平面，而是構成為：相對於往復移動方向Z以既定的斜率彼此交叉的曲面。詳細而言，段塊部50中，行進方向Z1側的第1側面51構成為相對於行進方向Z1斜率為正的曲面，另一方面後退方向Z2側的第2側面52構成為相對於行進方向Z1斜率為負的曲面。此外，當第1鏈條構件14與第2鏈條構件15一體化成直棒狀時，於往復移動方向Z相鄰的段塊部50彼此之間，一側的段塊部50的第1側面51與另一側的段塊部50的第2側面52會以彼此的凸面部分與凹面部分面接觸。此外，此時第1鏈條構件14及第2鏈條構件15的各段塊部50中，各個呈平面狀的頂面53會抵接於對方側鏈
條構件的鏈條元件16中的帶板狀的撓曲部23，從而達成於與往復移動方向Z交叉的方向上的定位。
The first side surface 51 on the advancing direction Z1 side and the second side surface 52 on the retreating direction Z2 side in the block portion 50 are not planes perpendicular to each other with respect to the reciprocating direction Z, but are configured to be in a predetermined direction relative to the reciprocating direction Z. Surfaces whose slopes intersect each other. Specifically, in the block portion 50, the first side surface 51 on the side in the advancing direction Z1 is configured as a curved surface with a positive slope with respect to the advancing direction Z1, while the second side surface 52 on the side in the retreating direction Z2 is configured as a curved surface with a positive slope relative to the advancing direction Z1. Z1 is a surface with a negative slope. In addition, when the first chain member 14 and the second chain member 15 are integrated into a straight rod shape, between the segment parts 50 adjacent to each other in the reciprocating direction Z, the first side surface 51 of the segment part 50 on one side The second side surface 52 of the segment portion 50 on the other side is in surface contact with each other with a convex portion and a concave portion. In addition, at this time, in each segment portion 50 of the first chain member 14 and the second chain member 15, each planar top surface 53 abuts against the other side chain.
The strip-shaped flexure 23 in the chain element 16 of the chain member achieves positioning in a direction intersecting the reciprocating direction Z.
其中，段塊部50亦可構成為：行進方向Z1側的第1側面51與後退方向Z2側的第2側面52分別包含凸面部分與凹面部分之兩者。此時，行進方向Z1側的第1側面51構成為：相對於行進方向Z1斜率為正的曲面部分與相對於行進方向Z1斜率為負的曲面部分相接的曲面。另一方面，後退方向Z2側的第2側面52構成為：相對於行進方向Z1斜率為負的曲面部分與相對於行進方向Z1斜率為正的曲面部分相接的曲面。根據該構成，當第1鏈條構件14及第2鏈條構件15的段塊部50彼此抵接時，第1側面51的凸面部分及凹面部分與第2側面52的凹面部分及凸面部分會以咬合的方式抵接。因此，能夠有效地抑制互相抵接的段塊部50彼此在與往復移動方向Z交叉的方向上的位置偏移的疑慮。
Wherein, the block portion 50 may be configured such that the first side surface 51 on the side in the advancing direction Z1 and the second side surface 52 on the side in the retreating direction Z2 include both a convex portion and a concave portion, respectively. At this time, the first side surface 51 on the traveling direction Z1 side is configured as a curved surface in which a curved surface portion with a positive slope relative to the traveling direction Z1 and a curved surface portion with a negative slope relative to the traveling direction Z1 meet. On the other hand, the second side surface 52 on the side in the backward direction Z2 is configured as a curved surface in which a curved surface portion having a negative slope relative to the advancing direction Z1 and a curved surface portion having a positive slope relative to the advancing direction Z1 meet. According to this configuration, when the segment portions 50 of the first chain member 14 and the second chain member 15 are in contact with each other, the convex portion and concave portion of the first side surface 51 and the concave portion and convex portion of the second side surface 52 will engage with each other. approach. Therefore, it is possible to effectively suppress the possibility of positional misalignment of the segment portions 50 that are in contact with each other in the direction intersecting the reciprocating direction Z. FIG.
此外，段塊部50亦可構成為：行進方向Z1側的第1側面51及後退方向Z2側的第2側面52當中至少一者的側面為相對於行進方向Z1具有斜率的曲面。例如，亦可構成為：行進方向Z1側的第1側面51及後退方向Z2側的第2側面52當中，一者的側面為相對於行進方向Z1具有斜率的曲面，亦可構成為：另一者的側面為相對於行進方向Z1具有斜率的平面。作為其中一例，第1鏈條構件14的段塊部50中，行進方向Z1側的第1側面51構成為相對於行進方向Z1的斜率為正或負的曲面，後退方向Z2側的第2側面52構成為相對於行進方向Z1具有斜率的平面。另一方面，第2鏈條構件15的段塊部50中，行進方向Z1側的第1側面51構成為相對於行進方向Z1具有斜率的平面，後退方向Z2側的
第2側面52構成為相對於行進方向Z1的斜率為負或正的曲面。以此種方式構成時，當第1鏈條構件14及第2鏈條構件15的段塊部50彼此抵接時，互為曲面所構成的第1側面51與第2側面52會以咬合的方式抵接。因此，能夠有效地抑制互相抵接的段塊部50彼此在與往復移動方向Z交叉的方向上的位置偏移的疑慮。
In addition, the block portion 50 may be configured such that at least one of the first side surface 51 on the advancing direction Z1 side and the second side surface 52 on the retreating direction Z2 side is a curved surface having an inclination with respect to the advancing direction Z1. For example, among the first side surface 51 on the side of the advancing direction Z1 and the second side surface 52 on the side of the retreating direction Z2, one of the side surfaces may be a curved surface having a slope with respect to the advancing direction Z1, or the other may be configured such that The side of the latter is a plane having a slope with respect to the direction of travel Z1. As one example, in the segment portion 50 of the first chain member 14, the first side surface 51 on the advancing direction Z1 side is configured as a curved surface with a positive or negative slope relative to the advancing direction Z1, and the second side surface 52 on the retreating direction Z2 side is configured as a curved surface. It is configured as a plane having a slope with respect to the traveling direction Z1. On the other hand, in the segment portion 50 of the second chain member 15, the first side surface 51 on the advancing direction Z1 side is formed as a plane having an inclination with respect to the advancing direction Z1, and the first side surface 51 on the retreating direction Z2 side
The second side surface 52 is configured as a curved surface with a negative or positive slope relative to the traveling direction Z1. When configured in this way, when the segment portions 50 of the first chain member 14 and the second chain member 15 abut against each other, the first side 51 and the second side 52 formed of mutually curved surfaces will abut against each other in an engaged manner. catch. Therefore, it is possible to effectively suppress the possibility of positional misalignment of the segment portions 50 that are in contact with each other in the direction intersecting the reciprocating direction Z. FIG.
接著，針對本實施方式的作用進行說明。
Next, the operation of this embodiment will be described.
又，當使用多個鏈條元件16製作既定長度的第1鏈條構件14及第2鏈條構件15時，首先串聯配置多個鏈條元件16。然後，直列方向上相鄰的鏈條元件16彼此之中一側的鏈條元件16的第1連結部24與另一側的鏈條元件16的第2連結部25連結。此時，一側的鏈條元件16的第1連結部24從鏈條元件16的寬度方向，也就是深度方向Y的任一側嵌入另一側的鏈條元件16的第2連結部25的卡合部26。然後，如圖6所示，形成多個鏈條元件16於直列方向上連結而成的既定長度的第1鏈條構件14及第2鏈條構件15。此時，若調整串聯連結的鏈條元件16的個數，則可將構成嚙合鏈條12的第1鏈條構件14及第2鏈條構件15的長度調整為任意的長度。
Moreover, when manufacturing the 1st chain member 14 and the 2nd chain member 15 of predetermined length using several chain elements 16, first arrange|position several chain elements 16 in series. Then, among the chain elements 16 adjacent in the serial direction, the first connecting portion 24 of the chain element 16 on one side is connected to the second connecting portion 25 of the chain element 16 on the other side. At this time, the first connecting portion 24 of one chain element 16 fits into the engaging portion of the second connecting portion 25 of the other chain element 16 from either side in the width direction of the chain element 16 , that is, in the depth direction Y. 26. Then, as shown in FIG. 6 , the first chain member 14 and the second chain member 15 having a predetermined length in which a plurality of chain elements 16 are connected in the serial direction are formed. At this time, if the number of chain elements 16 connected in series is adjusted, the lengths of the first chain member 14 and the second chain member 15 constituting the meshing chain 12 can be adjusted to an arbitrary length.
此外，製作如以上的第1鏈條構件14及第2鏈條構件15時，所需的構件數量只要撓曲部23與第1連結部24與第2連結部25一體成形之1種類的鏈條元件16即足。例如，串聯配置的多個連結板中直列方向上相鄰的連結板彼此通過連結銷而以能夠旋動的方式連結的構成中，除了連結板以外還需要如連結銷般的連結用構件。相對於此，本實施方式中，由於第1連結部24與第2連結部25與撓曲部23一體成形，故
不需要如連結銷這樣的連結用構件。
In addition, when manufacturing the above-mentioned first chain member 14 and second chain member 15, the number of required members is only one type of chain element 16 in which the flexure 23, the first connection part 24, and the second connection part 25 are integrally formed. That is enough. For example, among a plurality of connecting plates arranged in series, connecting plates adjacent in the serial direction are rotatably connected to each other by connecting pins, requiring connecting members such as connecting pins in addition to the connecting plates. In contrast, in the present embodiment, since the first connecting portion 24 and the second connecting portion 25 are integrally formed with the flexure portion 23,
A connecting member such as a connecting pin is not required.
此外，如圖1所示，由以上第1鏈條構件14及第2鏈條構件15所構成的嚙合鏈條12隨著鏈輪19的旋轉，其中鏈條元件16的撓曲部23會於收容部13內被導引至呈彎曲狀的誘導溝22而往復移動。此時，鏈輪19的齒尖會與第1鏈條構件14及第2鏈條構件15的段塊部50彼此嚙合而呈直棒狀的部分的段塊部50中第1連結部24的溝部48與第2連結部25的貫通孔49組合而成的穴進行嚙合。然後，第1鏈條構件14與第2鏈條構件15隨著該鏈輪19的旋轉，於收容部13內鏈條元件16中能夠彈性變形的撓曲部23會跟隨彎曲狀的誘導溝22而彎曲。
In addition, as shown in FIG. 1 , the meshing chain 12 composed of the above first chain member 14 and second chain member 15 rotates with the rotation of the sprocket 19, wherein the flexure portion 23 of the chain element 16 will be in the housing portion 13 It is guided to the curved induction groove 22 to reciprocate. At this time, the tooth tip of the sprocket 19 meshes with the segment portion 50 of the first chain member 14 and the second chain member 15 to form a straight rod-shaped portion of the segment portion 50 in the groove portion 48 of the first connecting portion 24 It engages with a hole formed in combination with the through-hole 49 of the second connecting portion 25 . Then, as the first chain member 14 and the second chain member 15 rotate along with the sprocket 19 , the elastically deformable flexible portion 23 of the chain element 16 in the housing portion 13 bends along the curved induction groove 22 .
此外，當第1鏈條構件14及第2鏈條構件15一起往行進方向Z1移動，段塊部50彼此互相嚙合時，位於行進方向Z1側的段塊部50的第2側面52會與位於後退方向Z2側的段塊部50的第1側面51抵接。此外，此時當互相抵接的段塊部50的第1側面51及段塊部50的第2側面52彼此共平面時，會產生例如兩者交會時的碰撞聲。相對於此，本實施方式中，由於互相抵接的段塊部50的第1側面51及段塊部50的第2側面52彼此皆為曲面，故藉由曲面彼此互相圓滑地嚙合而得以抑制像這樣的碰撞聲的產生。
In addition, when the first chain member 14 and the second chain member 15 move toward the advancing direction Z1 together and the segment parts 50 are engaged with each other, the second side surface 52 of the segment part 50 on the side in the advancing direction Z1 will be aligned with the second side 52 in the backward direction. The first side surface 51 of the block portion 50 on the Z2 side abuts against it. In addition, at this time, when the first side surface 51 of the segment portion 50 and the second side surface 52 of the segment portion 50 that are in contact with each other are coplanar with each other, for example, a collision sound will be generated when the two meet. On the other hand, in the present embodiment, since the first side surface 51 of the block portion 50 and the second side surface 52 of the block portion 50 that are in contact with each other are both curved surfaces, the curved surfaces are smoothly engaged with each other to suppress The generation of crashing sounds like this.
以下，參照圖8及圖9，針對位於後退方向Z2側的段塊部50的第1側面51對於位於行進方向Z1側的段塊部50的第2側面52從開始嚙合至嚙合結束的狀態進行說明。其中，圖8及圖9中，僅將隨著往行進方向Z1移動而嚙合有關之於往復移動方向Z相鄰的僅一對段塊部50彼此以實線表示，其他的構件則以虛線表示。
Hereinafter, with reference to FIGS. 8 and 9 , the first side surface 51 of the block portion 50 on the side in the backward direction Z2 is engaged with the second side face 52 of the block portion 50 on the side in the advancing direction Z1 from the start of meshing to the state of meshing completion. illustrate. Among them, in Fig. 8 and Fig. 9, only a pair of block parts 50 adjacent to the reciprocating movement direction Z that engage with each other as they move toward the traveling direction Z1 are represented by solid lines, and other members are represented by dotted lines. .
首先，如圖8所示，開始嚙合之後，位於行進方向Z1側的段塊部50的第2側面52中靠近頂面53那一側的凸面部分會與位於後退方向Z2側的段塊部50的第1側面51中靠近頂面53那一側的凹面部分接觸。然後，從該狀態開始鏈輪19進而往圖8中的順時鐘方向旋轉時，第1鏈條構件14及第2鏈條構件15會從圖8的狀態進而往行進方向Z1移動。接著，如圖9所示，位於行進方向Z1側的段塊部50的第2側面52中靠近頂面53那一側的凸面部分會於位於後退方向Z2側的段塊部50的第1側面51圓滑地滑動至靠近撓曲部23那一側。然後，從該狀態開始鏈輪19進而往圖9中的順時鐘方向旋轉時，第1鏈條構件14及第2鏈條構件15中的段塊部50彼此會互相抵接而一體化成直棒狀，成為圖7所示般的面接觸狀態。
First, as shown in FIG. 8 , after the meshing is started, the convex portion of the second side surface 52 of the block portion 50 on the side in the advancing direction Z1 that is close to the top surface 53 will be aligned with the block portion 50 on the side in the retreating direction Z2. The concave portion of the first side surface 51 that is closer to the top surface 53 is in contact with. Then, when the sprocket 19 rotates clockwise in FIG. 8 from this state, the first chain member 14 and the second chain member 15 move in the traveling direction Z1 from the state of FIG. 8 . Next, as shown in FIG. 9 , the convex portion of the second side surface 52 of the block portion 50 on the side in the advancing direction Z1 that is close to the top surface 53 will be positioned on the first side surface of the block portion 50 on the side in the retreating direction Z2. 51 smoothly slides to the side close to the flexure 23. Then, when the sprocket 19 is rotated clockwise in FIG. 9 from this state, the segment portions 50 in the first chain member 14 and the second chain member 15 will contact each other and be integrated into a straight rod shape. A state of surface contact as shown in FIG. 7 is achieved.
此時，第1鏈條構件14及第2鏈條構件15互相嚙合的段塊部50彼此之中，滑動抵接的第1側面51及第2側面52彼此為相對於往復移動方向Z以既定的斜率交叉的曲面。因此，於往復移動方向Z相鄰的段塊部50彼此之中，一側的段塊部50的第1側面51與另一側的段塊部50的第2側面52之間，在滑動時以往各自的傾斜方向滑行的方式相對移動。此外，藉由相互的鏈條構件中的段塊部50的頂面53抵接於對方側鏈條構件的撓曲部23的內側的面，從而使互相抵接的段塊部50彼此達成於與往復移動方向Z交叉的方向上的定位。此外，互相抵接的段塊部50彼此藉由第1側面51及第2側面52的凸面部分與凹面部分以咬合的方式抵接，從而抑制與往復移動方向Z交叉的方向上的位置偏移。
At this time, among the segment parts 50 where the first chain member 14 and the second chain member 15 are engaged with each other, the first side surface 51 and the second side surface 52 that are in sliding contact with each other have a predetermined slope with respect to the reciprocating direction Z. Intersecting surfaces. Therefore, among the adjacent segment parts 50 in the reciprocating direction Z, between the first side surface 51 of one segment part 50 and the second side surface 52 of the other segment part 50, when sliding In the past, they moved relative to each other by sliding in their respective inclined directions. In addition, since the top surface 53 of the segment portion 50 of the mutual chain members abuts against the inner surface of the flexure portion 23 of the other side chain member, the segment portions 50 that are in contact with each other achieve mutual reciprocation. Positioning in the direction where the moving direction Z intersects. In addition, the segment parts 50 that are in contact with each other contact each other in such a way that the convex and concave parts of the first side surface 51 and the second side surface 52 engage with each other, thereby suppressing positional displacement in a direction intersecting with the reciprocating direction Z. .

In the chain element 16 in this embodiment, the flexure 23 , the first connecting portion 24 , and the second connecting portion 25 are integrally formed by polyacetal (POM), which is an example of resin-based engineering plastic.
圖11及圖12中，段塊部50作為上側之第1端側的第1側面51是由垂直於往復移動方向Z的平面所構成。此外，圖11及圖12中，段塊部50作為下側之第2端側的第2側面52是由垂直於往復移動方向Z的平面所構成。往復移動方向Z對應於鏈條元件16的長度方向。此外，段塊部50中，與撓曲部23所在之側的面54相反側的面，也就是頂面53穿設有讓鏈輪19的齒尖嚙合的穴61。另一方面，段塊部50的撓曲部23所在之側的面54中第1端與第2端的中間位置形成有剖面矩形狀的***部62，其形成為沿著深度方向Y延伸。
In FIGS. 11 and 12 , the first side surface 51 on the first end side of the segment portion 50 as the upper side is constituted by a plane perpendicular to the reciprocating direction Z. As shown in FIG. In addition, in FIGS. 11 and 12 , the second side surface 52 on the second end side of the segment portion 50 as the lower side is constituted by a plane perpendicular to the reciprocating direction Z. As shown in FIG. The reciprocating direction Z corresponds to the length direction of the chain element 16 . In addition, in the segment portion 50 , the surface opposite to the surface 54 on which the flexure portion 23 is located, that is, the top surface 53 is pierced with holes 61 for meshing teeth tips of the sprocket 19 . On the other hand, on the surface 54 of the segment portion 50 on which the bending portion 23 is located, a raised portion 62 having a rectangular cross-section is formed at an intermediate position between the first end and the second end, and is formed to extend along the depth direction Y.
***部62中第2端側的部分是以如下方式支撐著帶板狀的撓曲部23：在與其第1端側的緣部接合的狀態下，其第2端側所相連的部分從第2端側突出越過段塊部50而呈懸臂梁狀。此外，***部62中，與撓曲部23的第1端側的緣部接合的部分旁鄰接第1端側的部分形成有剖面形狀與第2連結部25同樣是呈L字狀的凹條63，其沿著深度方向Y延伸。
The portion on the second end side of the protruding portion 62 supports the strip-shaped flexible portion 23 in such a manner that the portion connected to the second end side is connected to the second end side from the second end side in a state of being joined to the edge portion on the first end side. The two end sides protrude beyond the block portion 50 to form a cantilever beam. In addition, in the protruding portion 62 , the portion adjacent to the first end side adjacent to the portion joined to the edge portion on the first end side of the flexure portion 23 is formed with a groove having an L-shaped cross-sectional shape similar to that of the second connecting portion 25 . 63, which extends along the depth direction Y.
又，在製作本實施方式的往復驅動用鏈條之鏈條構件60時，直列方向上相鄰的鏈條元件16彼此之中一側的鏈條元件16的第1連結部24與另一側的鏈條元件16的第2連結部25連結。也就是說，直列方向上相鄰的鏈條元件16彼此之中，一側的鏈條元件16呈凸條的第2連結部25從鏈條元件16的寬度方向，也就是深度方向Y的任一側嵌入另一側的鏈條元件16的第1連結部24所形成的凹條63。以此方式，利用箱體形狀的第1連結部24中構成段塊部50的外形的表面部分以外的部分，藉此連結直列方向上相鄰的鏈條元件16彼此之中一側的鏈條元件16的第1連結部24與另一側的鏈條元件16的第2連結部25。
Moreover, when manufacturing the chain member 60 of the reciprocating drive chain of this embodiment, among the chain elements 16 adjacent to each other in the serial direction, the first connecting portion 24 of the chain element 16 on one side and the chain element 16 on the other side The second connecting part 25 is connected. That is to say, among the chain elements 16 adjacent to each other in the straight line direction, the second connecting portion 25 of the chain element 16 on one side is a convex line embedded from either side of the chain element 16 in the width direction, that is, in the depth direction Y. The groove 63 formed by the first connecting portion 24 of the other chain element 16 . In this manner, the chain elements 16 on one side of the adjacent chain elements 16 in the serial direction are connected by using the parts other than the surface portion constituting the outer shape of the block portion 50 in the box-shaped first connecting portion 24 . The first connecting part 24 of the first connecting part 24 and the second connecting part 25 of the chain element 16 on the other side.
此外，如圖10所示，本實施方式的往復驅動用鏈條之鏈條構件60藉由鏈條元件16的撓曲部23撓曲變形，從而能夠往與鏈條元件16的直列方向交叉的交叉方向的第1側，也就是圖10中的左側折曲。另一方面，由於構成鏈條構件60的各鏈條元件16中相較於撓曲部23位於第2側的段塊部50與於直列方向上相鄰的其他段塊部50以呈直棒狀的方式抵接，故鏈條構件60在圖10中與其第1側相反之作為右側的第2側無法折曲。
In addition, as shown in FIG. 10 , the chain member 60 of the reciprocating drive chain according to the present embodiment can be bent and deformed by the flexure portion 23 of the chain element 16 so that it can go to the second direction in the intersecting direction intersecting with the in-line direction of the chain element 16. 1 side, which is the left side in Figure 10, is bent. On the other hand, among the chain elements 16 constituting the chain member 60, the segment portion 50 located on the second side with respect to the flexure portion 23 and the other segment portions 50 adjacent in the straight direction are shaped like straight rods. Therefore, the second side of the chain member 60 which is opposite to its first side in FIG. 10 as the right side cannot be bent.
根據本實施方式，除了能夠享受第1實施方式(1-4)所示的效果以外，亦能夠享受如以下的效果。
According to this embodiment, in addition to the effects shown in the first embodiment (1-4), the following effects can also be enjoyed.
(2-1)為了構成往復驅動用鏈條之長條的鏈條構件60，能夠藉由調整串聯連結的鏈條元件16的個數，從而將1條鏈條構件60的長度調整為適合預計使用的動力機構的規格之最佳長度。因此，能夠使用在每種規格所適合之鏈條構件的長度彼此不同的多種規格的動力機構。
(2-1) In order to constitute the elongated chain member 60 of the reciprocating drive chain, the length of one chain member 60 can be adjusted to be suitable for the expected use of the power mechanism by adjusting the number of chain elements 16 connected in series. The optimal length of the specification. Therefore, it is possible to use power mechanisms of various specifications in which the lengths of the chain members to which the specifications are adapted differ from each other.
(2-2)能夠將可往與鏈條元件16的直列方向交叉的交叉方向的第1側折曲，卻因段塊部50彼此抵接而無法往相反的第2側折曲之這種非後彎(nobackbend)方式的往復驅動用鏈條使用在鏈條構件60的長度不同的多種規格的動力機構。
(2-2) It is possible to bend the first side in the intersecting direction intersecting the in-line direction of the chain elements 16, but cannot bend to the opposite second side because the segment parts 50 abut against each other. The chain for reciprocating drive of a nobackbend system uses the power mechanism of various specifications which differ in the length of the chain member 60. As shown in FIG.
(2-3)能夠藉由連結直列方向上相鄰的鏈條元件16彼此之中一側的鏈條元件16的第1連結部24與另一側的鏈條元件16的第2連結部25，從而於相較於撓曲部23靠與直列方向交叉的交叉方向的另一側通過第1連結部24而容易形成段塊部50。
(2-3) By connecting the first connecting portion 24 of the chain element 16 on one side and the second connecting portion 25 of the chain element 16 on the other side among the adjacent chain elements 16 in the serial direction, the The segment portion 50 is easily formed by the first connection portion 24 on the other side of the intersecting direction intersecting the in-line direction than the flexure portion 23 .
其中，上述實施方式亦可如以下所示的變形例進行變更。此外，亦可將實施方式所包含的構成與下述變形例所包含的構成任意組合，亦可將下述變形例所含的複數構成任意組合。
However, the above-described embodiment may be modified as modified examples shown below. In addition, it is also possible to arbitrarily combine the configurations included in the embodiment and the configurations included in the following modification examples, and to arbitrarily combine plural configurations included in the following modification examples.
‧如圖13所示，採用這種嚙合鏈條12的方式的往復驅動用鏈條的可動體移動裝置11中，亦可構成為：形成於收容部13的內面的誘導溝22設為曲率半徑較圖1所示的第1實施方式的情形更小的曲線。根據該構成，即使是當收容部13內需要增加誘導溝22的長度的情形，仍可縮短嚙合鏈條12在分岐方向X的收容部13的長度，藉此能夠將可動
體移動裝置11緊緻化。
‧As shown in FIG. 13, in the movable body moving device 11 of the reciprocating driving chain adopting the method of engaging the chain 12, it may also be configured such that the guiding groove 22 formed on the inner surface of the housing portion 13 has a smaller curvature radius. In the case of the first embodiment shown in FIG. 1 , the curve is even smaller. According to this structure, even if it is necessary to increase the length of the induction groove 22 in the housing portion 13, the length of the housing portion 13 in the branching direction X of the engaging chain 12 can be shortened, whereby the movable
The body moving device 11 is compacted.
‧如圖14所示，鏈條元件16中的撓曲部23亦可預先往與往復移動方向Z交叉的方向的一側彎曲。詳細而言，撓曲部23亦可預先往連結時形成段塊部50的第1連結部24及第2連結部25所在之側的相反側彎曲。根據該構成，相較於撓曲部23為平坦的帶板狀的情形，由於當第1鏈條構件14、第2鏈條構件15及鏈條構件60曲線地往復移動時能夠減少撓曲部23所產生的應力，故能夠縮小撓曲變形的撓曲部23的折曲半徑。因此，能夠縮小第1鏈條構件14、第2鏈條構件15及鏈條構件60的往復移動路徑所占有的空間。
‧As shown in FIG. 14 , the flexible portion 23 of the chain element 16 may be bent to one side in a direction intersecting with the reciprocating direction Z in advance. Specifically, the flexible portion 23 may be bent in advance to the side opposite to the side where the first connecting portion 24 and the second connecting portion 25 that form the segment portion 50 are located when they are connected. According to this configuration, compared with the case where the flexure portion 23 is flat and plate-shaped, when the first chain member 14, the second chain member 15, and the chain member 60 reciprocate in a curve, it is possible to reduce the occurrence of the deflection portion 23. Therefore, the bending radius of the flexure portion 23 can be reduced. Therefore, the space occupied by the reciprocating movement paths of the first chain member 14, the second chain member 15, and the chain member 60 can be reduced.
‧如圖15所示，隨著第1鏈條構件14及第2鏈條構件15的段塊部50彼此往行進方向Z1移動從而抵接而一體化成直棒狀時，段塊部50的頂面53亦可不與對方側鏈條構件的撓曲部23的內側的面抵接。詳細而言，亦可構成為：當於往復移動方向Z相鄰的段塊部50彼此的第1側面51與第2側面52面接觸而一體化成直棒狀時，各段塊部50的頂面53與該頂面53所面向的撓曲部23的內側的面之間形成有間隙64。根據該構成，能夠抑制段塊部50從側面對撓曲部23進行抵接所導致的撓曲部23的撓曲變形，從而能夠降低施加於撓曲部23的板厚方向的應力，使撓曲部23的強度提升。
‧As shown in FIG. 15 , when the segment parts 50 of the first chain member 14 and the second chain member 15 move toward the traveling direction Z1 and contact each other to form a straight rod shape, the top surface 53 of the segment part 50 It does not need to be in contact with the inner surface of the flexure 23 of the other side chain member. In detail, it may also be configured such that when the first side surfaces 51 and the second side surfaces 52 of the segment parts 50 adjacent to each other in the reciprocating direction Z are in surface contact and integrated into a straight rod shape, the top of each segment part 50 A gap 64 is formed between the surface 53 and the surface inside the flexure 23 that the top surface 53 faces. According to this structure, the bending deformation of the bending part 23 caused by the contact of the segment part 50 on the bending part 23 from the side surface can be suppressed, and the stress applied to the bending part 23 in the plate thickness direction can be reduced and the bending can be reduced. The strength of the curved portion 23 is improved.
‧如圖16或圖17所示，鏈條元件16的撓曲部23亦可為如下構成：能夠對例如段塊部50等該鏈條元件16中撓曲部23以外的部分進行裝卸。詳細而言，第1連結部24與第2連結部25一體化而成的撓曲部23與段塊部50為分體構成。此時，撓曲部23藉由位於該第1端側
的第1連結部24及位於第2端側的第2連結部25從深度方向Y的一側嵌進形成於段塊部50的一側面的卡止凹部65及卡止凹部66，從而與段塊部50一體化。詳細而言，段塊部50是以如下態樣組裝：將直列方向上相鄰的鏈條元件16彼此之中一側的鏈條元件16的第1連結部24與另一側的鏈條元件16的第2連結部25之兩者進行連結。根據該構成，能夠將以可撓性相對較高的材質為宜的撓曲部23，以及以剛性相對較高的材質為宜的段塊部50等撓曲部23以外的部分分開而簡單地製造。此外，於直列方向上相鄰的第1連結部24與第2連結部25並排的狀態下，能夠藉由將分體構成的段塊部50組裝於兩者上，從而能夠簡單地形成連結第1連結部24與第2連結部25的段塊部50。
‧As shown in FIG. 16 or FIG. 17 , the flexure portion 23 of the chain element 16 may be configured such that parts other than the flexure portion 23 of the chain element 16 such as the segment portion 50 can be attached and detached. Specifically, the flexure portion 23 and the segment portion 50 formed by integrating the first connection portion 24 and the second connection portion 25 are formed separately. At this time, the flexure 23 is positioned at the first end side
The first connecting portion 24 and the second connecting portion 25 on the second end side are fitted into the locking recess 65 and the locking recess 66 formed on one side surface of the segment block portion 50 from one side in the depth direction Y, so as to be connected with the segment The block portion 50 is integrated. Specifically, the segment portion 50 is assembled in such a manner that the first connecting portion 24 of the chain element 16 on one side and the first connecting portion 24 of the chain element 16 on the other side among the chain elements 16 adjacent to each other in the serial direction are assembled. 2. The two connecting parts 25 are connected. According to this configuration, parts other than the flexure portion 23, such as the flexure portion 23, which is preferably made of a relatively high-flexibility material, and the segment portion 50, which is preferably a relatively high-rigidity material, can be separated and easily manufacture. In addition, in the state where the first connecting portion 24 and the second connecting portion 25 adjacent to each other in the serial direction are aligned, the segment portion 50 formed separately can be assembled to both, so that the connection of the second connecting portion 24 can be easily formed. The block part 50 of the 1st connection part 24 and the 2nd connection part 25.
‧如圖18A及圖18B所示，亦可為如下構成：撓曲部23的第1端側的第1連結部24兼用段塊部50，撓曲部23的第2端側的第2連結部25隔著間隙67與形成於段塊部50的側面的卡止凹部66嵌合。根據該構成，由於第1連結部24兼用的段塊部50上所形成的卡止凹部66與第2連結部25之間的連結處能夠被間隙67稍微鬆脫或游離，故即使不賦予撓曲部23較大的撓曲變形，亦可將鏈條構件彎曲成曲線狀。因此，由於鏈條元件16的撓曲部23的變形量變小，同時撓曲變形產生的應力也變小，故能夠使撓曲部23的強度、例如挫屈強度、撓曲強度、彎曲強度等提升。
‧As shown in FIG. 18A and FIG. 18B , the following configuration can also be adopted: the first connection portion 24 on the first end side of the flexure portion 23 also serves as the block portion 50, and the second connection portion on the second end side of the flexure portion 23 The portion 25 is fitted into a locking recess 66 formed on the side surface of the segment portion 50 via a gap 67 . According to this configuration, since the joint between the locking concave portion 66 formed on the segment portion 50 serving as the first joint portion 24 and the second joint portion 25 can be slightly loosened or freed by the gap 67, even if no flexure is given, The large deflection deformation of the curved portion 23 can also bend the chain member into a curved shape. Therefore, since the amount of deformation of the flexure 23 of the chain element 16 becomes smaller, the stress generated by flexure deformation also becomes smaller, so the strength of the flexure 23, such as buckling strength, flexural strength, bending strength, etc., can be improved. .

詳細而言，該變形例中的嚙合鏈條12藉由第1鏈條構件14與第2鏈條構件15於行進方向Z1移動，從而使段塊部50彼此互相嚙合而一體化成曲棒狀。另一方面，該變形例中的嚙合鏈條12藉由從第1鏈條構件14與第2鏈條構件15相互嚙合而一體化成曲棒狀的嚙合狀態往與行進方向Z1相反的後退方向Z2移動，從而使段塊部50彼此相互地脫離嚙合而分岐。此外，收容部13內，鏈輪19配置為：齒尖從第2鏈條構件15所在之側於分岐方向X對嚙合鏈條12中第1鏈條構件14與第2鏈條構件15互相嚙合而成為曲棒狀的部分進行嚙合。其中，收容部13內設有呈適當曲線形狀的誘導溝22，其誘導從嚙合狀態脫離嚙合而分岐的第1鏈條構件14與第2鏈條構件15使其以曲線的方式移動。
Specifically, in the meshing chain 12 in this modified example, the first chain member 14 and the second chain member 15 are moved in the traveling direction Z1, so that the segment parts 50 are meshed with each other and integrated into a bent rod shape. On the other hand, the meshing chain 12 in this modified example moves from the meshing state in which the first chain member 14 and the second chain member 15 are meshed with each other and integrated into a bent bar shape to the backward direction Z2 opposite to the advancing direction Z1, thereby The segment parts 50 are disengaged from each other and branched. In addition, in the housing portion 13, the sprocket 19 is arranged such that the tooth tip is engaged with the chain 12 in the branching direction X from the side where the second chain member 15 is located. The first chain member 14 and the second chain member 15 mesh with each other to form a curved bar Shaped parts are meshed. Wherein, the receiving portion 13 is provided with a suitable curved induction groove 22, which induces the first chain member 14 and the second chain member 15 that are disengaged from the meshed state and branched to move in a curved manner.
此外，該變形例中構成第1鏈條構件14與第2鏈條構件15的鏈條元件16，其基本構成亦與第1實施方式中的鏈條元件16大致相同。詳細而言，該變形例中的鏈條元件16亦具有帶板狀的撓曲部23、撓曲部23中位於第1端側的塊狀的第1連結部24、及撓曲部23中位於第2
端側的塊狀的第2連結部25。此外，藉由直列方向上相鄰的鏈條元件16彼此之中一側的鏈條元件16的第1連結部24與另一側的鏈條元件16的第2連結部25部分地嵌合連結，從而形成第1連結部24的外形的一部分與第2連結部25的外形的一部分相接的形狀的段塊部50。
In addition, the basic structure of the chain element 16 which comprises the 1st chain member 14 and the 2nd chain member 15 in this modification is substantially the same as that of the chain element 16 in 1st Embodiment. Specifically, the chain element 16 in this modified example also has a strip-shaped flexure 23, a block-shaped first connecting portion 24 located at the first end side of the flexure 23, and a block-shaped first connecting portion 24 located at the first end side of the flexure 23. 2nd
Block-shaped second connecting portion 25 on the end side. In addition, among chain elements 16 adjacent to each other in the serial direction, the first connecting portion 24 of one chain element 16 is partially fitted and connected with the second connecting portion 25 of the other chain element 16, thereby forming A segment portion 50 having a shape in which a part of the outer shape of the first connecting portion 24 is in contact with a part of the outer shape of the second connecting portion 25 .
當第1鏈條構件14與第2鏈條構件15一體化成曲棒狀時，於往復移動方向Z相鄰的段塊部50彼此之間，一側的段塊部50的行進方向Z1側的第1側面51與另一側的段塊部50的後退方向Z2側的第2側面52會進行面接觸。此時，段塊部50的第1側面51與第2側面52會分別地形成如下的面形狀：當往復移動方向Z相鄰的段塊部50彼此的第1側面51與第2側面52進行面接觸時，能夠使於往復移動方向Z相鄰的段塊部50彼此一體化成曲棒狀。像這樣構成的變形例的嚙合鏈條12適合如下情形：在第1鏈條構件14與第2鏈條構件15相互嚙合而一體化成棒狀的嚙合狀態時，想要使安裝於行進方向Z1側的端部的可動體18以曲線的方式移動而非以直線的方式移動。

At this time, the first side surface 51 and the second side surface 52 of the segment part 50 respectively form the following surface shapes: In the case of surface contact, the segment portions 50 adjacent to each other in the reciprocating direction Z can be integrated into a bent rod shape. The meshing chain 12 of the modified example configured in this way is suitable for the case where it is desired to attach the end portion on the traveling direction Z1 side when the first chain member 14 and the second chain member 15 are meshed with each other and integrated into a rod-shaped meshing state. The movable body 18 moves in a curved manner rather than in a straight line.
‧如圖36所示，當往復驅動用鏈條為與圖10所示的第2實施方式相同的這種非後彎方式時，亦可構成為：鏈條構件60在往復移動方向Z相鄰的段塊部50彼此抵接的狀態下一體化成曲棒狀。該圖36所示的變形例與圖10所示的第2實施方式相比之下，該段塊部50的形狀有所不同。詳細而言，圖10所示的第2實施方式中，段塊部50的第1端側的第1側面51及第2端側的第2側面52分別是由相對於往復移動方向Z垂直的平面所構成。
‧As shown in FIG. 36, when the chain for reciprocating drive is of the same non-bending type as that of the second embodiment shown in FIG. The block portions 50 are integrated into a bent rod shape in a state of being in contact with each other. The modified example shown in FIG. 36 differs from the second embodiment shown in FIG. 10 in the shape of the segment portion 50 . In detail, in the second embodiment shown in FIG. composed of planes.
相對於此，圖36所示的變形例中，段塊部50的第1端側
的第1側面51及第2端側的第2側面52分別由相對於往復移動方向Z以既定的斜率交叉的面所構成。詳細而言，段塊部50的第1側面51與第2側面52會分別地形成如下的面形狀：當往復移動方向Z相鄰的段塊部50彼此的第1側面51與第2側面52進行面接觸時，能夠使於往復移動方向Z相鄰的段塊部50彼此抵接而成曲棒狀。此時，段塊部50的第1側面51與第2側面52的面形狀只要為相對於往復移動方向Z以既定的斜率交叉的面形狀，則可分別為平面形狀，亦可為曲面形狀。

The first side surface 51 and the second side surface 52 on the second end side are respectively constituted by surfaces intersecting with a predetermined slope with respect to the reciprocating movement direction Z. Specifically, the first side surface 51 and the second side surface 52 of the block portion 50 respectively form the following surface shapes: When performing surface contact, the segment portions 50 adjacent in the reciprocating direction Z can be brought into contact with each other to form a bent rod shape. At this time, the surface shapes of the first side surface 51 and the second side surface 52 of the segment portion 50 may be planar or curved as long as they intersect with the reciprocating direction Z at a predetermined slope.
如圖36所示，當往復移動方向Z相鄰的段塊部50彼此抵接時，鏈條構件60會成為如下般的S字狀：以鏈輪19嚙合的位置為界，例如該位置的下側往左方折曲，另一方面該位置的上側往右方彎曲。其中，亦可將段塊部50的第1端側的第1側面51及第2端側的第2側面52的面形狀分別適當地變更，使當往復移動方向Z相鄰的段塊部50彼此抵接時，例如從正面觀看鏈條構件60呈大致C字狀。
As shown in FIG. 36 , when adjacent segment portions 50 in the reciprocating direction Z abut against each other, the chain member 60 becomes an S-shape as follows: bounded by the position where the sprocket 19 engages, for example, the lower part of the position. The side is bent to the left, and on the other hand, the upper side of the position is bent to the right. Among them, the surface shapes of the first side surface 51 on the first end side and the second side surface 52 on the second end side of the segment part 50 can also be appropriately changed, so that the segment parts 50 adjacent to each other in the reciprocating direction Z When abutted against each other, the chain member 60 has a substantially C-shape when viewed from the front, for example.

‧鏈條元件16亦可對撓曲部23與段塊部50使用不同的樹脂材料來形成該等。例如鏈條元件16中，若將撓曲部23以可撓性相對於撓曲部23以外的部分高的材質構成，則能夠於鏈條構件以曲線的方式往復移動時輕易地使撓曲部23撓曲變形。例如，撓曲部23可藉由使用聚醯胺(PA)、聚縮醛(POM)及聚對苯二甲酸丁二醇酯(PBT)等具有某種程度變形能的樹脂材料，從而輕易地撓曲變形。段塊部50可藉由作為
超級工程塑膠之一例的PEEK(聚醚醚酮)或作為纖維強化塑膠之一例的PA6-GF30(聚醯胺6-玻璃纖維30%)等增加縱彈性係數從而提升自立性能。
‧The chain element 16 can also be formed by using different resin materials for the flexure 23 and the segment portion 50 . For example, in the chain element 16, if the flexure portion 23 is made of a material with high flexibility relative to parts other than the flexure portion 23, the flexure portion 23 can be easily flexed when the chain member reciprocates in a curved manner. curved deformation.

‧鏈條元件16亦可為如下構成：至少段塊部50的表面，尤其是行進方向Z1側的第1側面51及後退方向Z2側的第2側面52較其他部分的表面軟質。根據該構成，例如當第1鏈條構件14等鏈條構件於直線上往復移動時，雖然其往復移動方向Z相鄰的段塊部50彼此會抵接，但能夠抑制其抵接時所產生的噪音。
‧The chain element 16 may be configured such that at least the surface of the segment portion 50, especially the first side surface 51 on the side in the advancing direction Z1 and the second side surface 52 on the side in the backward direction Z2 are softer than the surfaces of other parts. According to this configuration, for example, when chain members such as the first chain member 14 reciprocate on a straight line, although the segment portions 50 adjacent to each other in the reciprocating direction Z contact each other, noise generated at the time of contact can be suppressed. .
‧當往復驅動用鏈條為嚙合鏈條12時，第1鏈條構件14及第2鏈條構件15當中一側的鏈條構件的鏈條元件16的段塊部50與另一側的鏈條構件的鏈條元件16的段塊部50亦可互為不同的材質。例如，亦可一側用聚醯胺(PA)另一側用聚縮醛(POM)、或一側用聚縮醛(POM)另一側用聚對苯二甲酸丁二醇酯(PBT)、或一側用聚對苯二甲酸丁二醇酯(PBT)另一側用聚醯胺(PA)。根據該構成，由於是縱彈性係數接近的不同2種類的材質，與互相嚙合的一對鏈條構件的段塊部50彼此為相同材質的情形相比能夠降低鏈條構件彼此黏結磨耗的風險。

For example, it is also possible to use polyamide (PA) on one side and polyacetal (POM) on the other side, or use polyacetal (POM) on one side and polybutylene terephthalate (PBT) on the other side. , or use polybutylene terephthalate (PBT) on one side and polyamide (PA) on the other. According to this configuration, since the longitudinal elastic modulus is close to two different types of materials, compared with the case where the segment portions 50 of a pair of chain members meshing with each other are made of the same material, the risk of the chain members sticking to each other can be reduced.
‧用以使往復驅動用鏈條往復移動的驅動機構亦可為鏈輪19以外者。例如圖16~圖20所示的嚙合鏈條12的情形，亦可於撓曲部23或段塊部50中分岐方向X朝外側的面設置齒條，並配置嚙合該齒條的小齒輪。或者，於鏈條構件上刻出螺紋，以導引螺桿的方式驅動，或使滾輪與鏈條構件摩擦卡合，以該滾輪的旋轉來驅動，或於鏈條構件的末端加裝致動器進行驅動。
