[現有技術文獻] [專利文獻] [專利文獻1] 日本專利特開2001-71227號公報[Prior Art Document] [Patent Document] [Patent Document 1] Japanese Patent Laid-Open No. 2001-71227
搬運鏈是經由傳動構件例如鏈輪(sprocket)而呈環狀地配置並旋轉。保持部是從搬運鏈朝徑向外方突出。因此,搬運鏈的直徑容易變大。The conveyance chain is circularly arranged and rotated via a transmission member such as a sprocket. The holding portion projects radially outward from the conveying chain. Therefore, the diameter of the conveyance chain tends to be large.
本發明是有鑒於所述情況而完成,其目的在於:提供一種在呈環狀配置的情況下,可減小直徑的搬運鏈。The present invention has been made in view of the circumstances described above, and an object thereof is to provide a conveying chain capable of reducing the diameter when arranged in a ring shape.
本發明的搬運鏈包括:內板及外板,經由銷而交替地連結;以及保持部,設置於所述銷,且具有:對於工具或工具筒進行保持的凹部。所述搬運鏈中,所述凹部是朝所述銷的軸向凹陷。The conveying chain of the present invention includes an inner plate and an outer plate that are alternately connected via pins, and a holding portion provided on the pin and having a recessed portion for holding a tool or a tool barrel. In the conveying chain, the recessed portion is recessed in an axial direction of the pin.
本發明中,工具或工具筒相對於凹部而沿銷的軸向插拔,從而抑制工具或工具筒從呈環狀配置的搬運鏈朝徑向外方突出。In the present invention, the tool or the tool barrel is inserted and pulled out in the axial direction of the pin with respect to the recess, so that the tool or the tool barrel is prevented from protruding radially outward from the conveying chain arranged in a ring shape.
本發明的搬運鏈中,能夠繞著所述銷的軸旋轉的所述保持部是從所述銷的端部朝所述軸向突出,所述凹部的開口位於所述保持部的突出端部。In the conveying chain of the present invention, the holding portion capable of rotating about the axis of the pin protrudes from an end portion of the pin toward the axial direction, and an opening of the recessed portion is located at a protruding end portion of the holding portion. .
本發明中,工具或工具筒可轉動地連結於銷的端部並從銷突出,因此搬運鏈能以銷為支點而朝兩方向轉動。與僅朝單方向轉動的搬運鏈相比,可容易地變更搬運鏈的配置。In the present invention, a tool or a tool cartridge is rotatably connected to the end of the pin and protrudes from the pin, so the conveying chain can be rotated in both directions with the pin as a fulcrum. The arrangement of the conveying chain can be easily changed compared to a conveying chain that only rotates in one direction.
本發明的搬運鏈中,所述保持部是由單一零件所構成。In the conveying chain of the present invention, the holding portion is composed of a single component.
本發明中,保持部是由單一零件所構成,而且設置於銷的端部,因此銷的軸向上的保持部的尺寸精度不會影響到內板、外板及銷的裝配精度。可提高銷的軸向上的製品整體(搬運鏈)的精度。In the present invention, the holding portion is composed of a single part and is provided at the end of the pin, so the dimensional accuracy of the holding portion in the axial direction of the pin does not affect the assembly accuracy of the inner plate, the outer plate, and the pin. The accuracy of the entire product (conveying chain) in the axial direction of the pin can be improved.
本發明的搬運鏈中,所述保持部具備:相向的兩個U狀板部,在所述兩個U狀板部之間設有加強銷。 In the conveying chain of the present invention, the holding portion includes two U-shaped plate portions facing each other, and a reinforcing pin is provided between the two U-shaped plate portions.
本發明中,藉由加強銷來加強保持部。 In the present invention, the holding portion is reinforced by a reinforcing pin.
本發明的搬運鏈更包括:夾持構件,配置於所述保持部的相鄰處,夾持所述工具或工具筒;以及支持板,以一表面支持所述夾持構件,且相對於所述銷的軸心成直角。 The conveying chain of the present invention further includes: a clamping member disposed adjacent to the holding portion to clamp the tool or a tool barrel; and a support plate to support the clamping member with one surface and be opposite to The axis of the pin is at right angles.
本發明中,支持夾持構件的支持板與銷的軸心成直角,因此可抑制銷的軸向上的夾持構件的位置偏離。因此,可防止夾持構件的位置偏離原本的位置而導致的不平衡負載作用於夾持構件,從而延長夾持構件的耐久時間。 In the present invention, since the support plate supporting the clamping member is at a right angle to the axis of the pin, the position deviation of the clamping member in the axial direction of the pin can be suppressed. Therefore, it is possible to prevent an unbalanced load caused by the position of the clamping member from being deviated from the original position, and to extend the durability time of the clamping member.
本發明的搬運鏈中,工具或工具筒相對於凹部而沿銷的軸向插拔,因此可抑制工具或工具筒從呈環狀配置的搬運鏈朝徑向外方突出。因此可抑制搬運鏈的直徑變大。 In the conveying chain of the present invention, since the tool or the tool barrel is inserted and removed in the axial direction of the pin with respect to the recessed portion, it is possible to prevent the tool or the tool barrel from protruding radially outward from the conveying chain arranged in a ring. Therefore, an increase in the diameter of the conveyance chain can be suppressed.

In addition, instead of the coil spring 6, two opposing elastic members (for example, rubber members) may be provided on the support plate 8, and the tool barrel may be held by the two elastic members.
接下來,對所述的搬運鏈1、和沿與銷110的軸心正交的方向插拔工具筒的參考搬運鏈100進行比較。Next, the above-mentioned conveying chain 1 is compared with a reference conveying chain 100 that inserts and extracts a tool barrel in a direction orthogonal to the axis of the pin 110.
圖5是概略表示參考搬運鏈100的一例的側面圖。如圖5所示,參考搬運鏈100的保持部107具備:相向的兩個保持板107a、107a。在兩個保持板107a、107a之間,設有兩個內板103、103及輥105。保持板107a亦作為外板102而發揮功能。FIG. 5 is a side view schematically showing an example of the reference transport chain 100. As shown in FIG. 5, the holding portion 107 of the reference transport chain 100 includes two holding plates 107 a and 107 a facing each other. Between the two holding plates 107a and 107a, two inner plates 103 and 103 and a roller 105 are provided. The holding plate 107a also functions as the outer plate 102.
在所述保持板107a的相鄰處,設有兩個外板102、102、兩個內板103、103、襯套(圖略)及輥105。在保持板107a、外板102及內板103上分別設有貫穿孔,貫穿孔、襯套及輥105是同軸地配置。在貫穿孔、襯套及輥105中***有銷110,從而,保持板107a、內板103、外板102及輥105相連結。保持板107a是朝銷110的徑向突出,在保持板107a的突出端部,設有:保持工具筒150的凹部。另外,外板102、內板103及輥105是與搬運鏈1同樣地構成。Adjacent to the holding plate 107a, two outer plates 102, 102, two inner plates 103, 103, a bushing (not shown), and a roller 105 are provided. The holding plate 107a, the outer plate 102, and the inner plate 103 are respectively provided with through holes, and the through holes, the bushes, and the rollers 105 are arranged coaxially. A pin 110 is inserted into the through hole, the bush, and the roller 105, and the holding plate 107 a, the inner plate 103, the outer plate 102, and the roller 105 are connected to each other. The holding plate 107 a protrudes in the radial direction of the pin 110. A protruding portion of the holding plate 107 a is provided with a recessed portion holding the tool barrel 150. The outer plate 102, the inner plate 103, and the roller 105 are configured in the same manner as the conveyance chain 1.
在與保持板107a鄰接的外板102上,設有支持板108。支持板108是從外板102的長邊緣部突出,並以與銷110平行的方式而彎曲。在支持板108上,支持有:固定工具筒150的U狀的盤簧106。A support plate 108 is provided on the outer plate 102 adjacent to the holding plate 107a. The support plate 108 protrudes from the long edge portion of the outer plate 102 and is bent so as to be parallel to the pin 110. The support plate 108 supports a U-shaped coil spring 106 to which the tool barrel 150 is fixed.
在參考搬運鏈100呈環狀地配置的情況下,工具筒150是朝徑向外方(圖5的上方)從保持部107被拆卸,並朝徑向內方(圖5的下方)***保持部107。因此,在保持部107保持著工具筒150的情況下,工具筒朝徑向外方大幅突出。When the reference conveying chain 100 is arranged in a ring shape, the tool barrel 150 is detached from the holding portion 107 outward in the radial direction (upward in FIG. 5), and is inserted and held inward in the radial direction (downward in FIG. 5). Department 107. Therefore, when the tool holder 150 is held by the holding portion 107, the tool holder projects significantly outward in the radial direction.
另一方面,如圖1所示,在搬運鏈1中,工具筒相對於凹部7d而沿銷10的軸向插拔,因此可抑制工具筒從呈環狀配置的搬運鏈1朝徑向外方(圖1的左方)突出。因此,可抑制呈環狀配置的搬運鏈1的直徑變大。On the other hand, as shown in FIG. 1, in the conveying chain 1, the tool barrel is inserted and removed in the axial direction of the pin 10 with respect to the recessed portion 7 d. Therefore, it is possible to suppress the tool barrel from moving radially outward from the conveying chain 1 in a ring shape. The square (left of Fig. 1) protrudes. Therefore, it is possible to suppress the diameter of the conveyance chain 1 arranged in a ring shape from increasing.
在參考搬運鏈100中,沿著圖5的表面背面方向而排列有保持板107a。排列的保持板107a可朝彼此遠離的方向轉動,但由於保持板107a會彼此干涉,因此無法朝接近的方向轉動。即,參考搬運鏈100僅可單向轉動。In the reference conveyance chain 100, the holding plates 107 a are arranged along the front-back direction in FIG. 5. The aligned holding plates 107a can be rotated in directions away from each other, but since the holding plates 107a interfere with each other, they cannot be rotated in the approaching direction. That is, the reference conveyance chain 100 can only rotate in one direction.
另一方面,如圖1所示,在搬運鏈1中,工具筒是可轉動地連結於銷10的端部,且朝銷10的軸向突出,因此搬運鏈1能以銷10為支點而雙向轉動。這是因為,無論朝哪個方向轉動,保持部7皆是彼此遠離。因此,與參考搬運鏈100相比,可容易地變更搬運鏈1的配置或佈局(layout)。On the other hand, as shown in FIG. 1, in the conveying chain 1, the tool barrel is rotatably connected to the end of the pin 10 and protrudes in the axial direction of the pin 10. Turn in both directions. This is because the holding portions 7 move away from each other no matter which direction they are turned. Therefore, it is possible to easily change the arrangement or layout of the transportation chain 1 compared to the reference transportation chain 100.
如圖5所示,在參考搬運鏈100中,外板102、內板103、保持板107a及輥105是沿銷110的軸向並排設置、並進行裝配。因此,即使在保持板107a的尺寸精度高的情況下,保持板107a、107a間的尺寸精度亦會影響到保持板107a以外的零件,即外板102、內板103及輥105的尺寸精度及銷110的軸向上的各零件的裝配精度。As shown in FIG. 5, in the reference conveyance chain 100, the outer plate 102, the inner plate 103, the holding plate 107 a, and the roller 105 are arranged side by side in the axial direction of the pin 110 and are assembled. Therefore, even when the dimensional accuracy of the holding plate 107a is high, the dimensional accuracy between the holding plates 107a and 107a will affect parts other than the holding plate 107a, that is, the dimensional accuracy of the outer plate 102, the inner plate 103, and the roller 105 and Assembly accuracy of each component in the axial direction of the pin 110.
另一方面,如圖1所示,搬運鏈1的保持部7是由單一零件所構成,且設於銷10的端部,而且,U狀板部7a是沿與銷10正交的方向並排設置,因此U狀板部7a間的尺寸精度不會影響到保持部7以外的零件的尺寸精度或銷10的軸向上的各零件的裝配精度,從而可提高搬運鏈1的精度。On the other hand, as shown in FIG. 1, the holding portion 7 of the conveying chain 1 is composed of a single part and is provided at an end portion of the pin 10, and the U-shaped plate portions 7 a are arranged side by side in a direction orthogonal to the pin 10 Because of this arrangement, the dimensional accuracy between the U-shaped plate portions 7 a does not affect the dimensional accuracy of parts other than the holding portion 7 or the assembly accuracy of each component in the axial direction of the pin 10, thereby improving the accuracy of the conveying chain 1.
在參考搬運鏈100中,如圖5所示,支持板108彎折,根據彎折程度,與銷110的軸心正交的方向上的支持板108的位置會有所變更。即,根據彎曲加工的精度,與銷110的軸心正交的方向上的盤簧106的位置會有所偏置。In the reference conveying chain 100, as shown in FIG. 5, the support plate 108 is bent, and the position of the support plate 108 in a direction orthogonal to the axis of the pin 110 is changed according to the degree of bending. That is, the position of the coil spring 106 in the direction orthogonal to the axis of the pin 110 is offset depending on the accuracy of the bending process.
另一方面,如圖1所示,在搬運鏈1中,支持板8是與銷10的軸心成直角,因此銷10的軸向上的盤簧6的位置偏離得以被抑制。因此,可防止盤簧6的位置從原本的位置發生偏置而導致不平衡負載(unbalanced load)從工具筒作用於盤簧6,從而可延長盤簧6的耐久時間。On the other hand, as shown in FIG. 1, in the conveying chain 1, the support plate 8 is at a right angle to the axis of the pin 10, so that the positional deviation of the coil spring 6 in the axial direction of the pin 10 is suppressed. Therefore, the position of the coil spring 6 can be prevented from being offset from the original position, and an unbalanced load can be prevented from acting on the coil spring 6 from the tool barrel, so that the durability time of the coil spring 6 can be extended.
