Description

棒材供給機 Bar feeder

本發明係關於一種棒材供給機，詳言之，係關於沿著棒材的長度方向軸線將棒材饋送到棒材加工機之棒材供給機。 The present invention relates to a bar feeding machine, in particular, to a bar feeding machine which feeds a bar to a bar processing machine along the lengthwise axis of the bar.

棒材供給機一般而言係具有：從上方承接一根棒材，沿著饋送軸線導引所承接的棒材之導軌；為了將接到導軌內的棒材饋送到棒材加工機，從後方往前方將棒材往棒材加工機推之進給推桿；以及驅動進給推桿之驅動裝置。 Generally speaking, the bar feeding machine has a guide rail that receives a bar from above and guides the received bar along the feeding axis; A feed push rod that pushes the bar forward to the bar processing machine; and a drive device that drives the feed push rod.

饋送到棒材加工機之棒材會***棒材加工機的主軸的貫通孔，棒材的前端部分由主軸的夾頭(chuck)加以保持住。使主軸轉動，就可利用棒材加工機的加工部(例如車刀(bite))對棒材的前端部分進行加工。將經棒材的前端部分的加工而形成的加工品切下來後，棒材由進給推桿將之再往前饋送，形成下一個加工品後再切下來。 A bar fed to the bar processing machine is inserted into a through hole of a main shaft of the bar processing machine, and the front end portion of the bar is held by a chuck of the main shaft. By rotating the main shaft, the front end portion of the bar can be machined by a processing unit (for example, a bit) of the bar processing machine. After the processed product formed by the processing of the front end of the bar is cut off, the bar is fed forward by the feed push rod, and the next processed product is formed before being cut off.

本案申請人曾以利用可更換的外套管而可將相同的進給推桿***不同孔徑的主軸的貫通孔之棒材供給機，取得日本專利(專利文獻1)。 The applicant of this application once obtained a Japanese patent (Patent Document 1) for a rod material feeding machine that can insert the same feed push rod into the through hole of the main shaft with different apertures by using a replaceable outer sleeve.

包含專利文獻1的裝置在內，傳統的棒材供給機都是利用導軌來導引進給推桿。與進給推桿的長度方向軸線垂直之導軌的橫斷面係形成為圓弧狀斷面。 Including the device of Patent Document 1, conventional bar feeders use guide rails to guide the feeding push rods. The cross-section of the guide rail perpendicular to the longitudinal axis of the feed push rod is formed into an arc-shaped cross-section.

而且，為了減輕進給推桿與導軌之間的摩擦阻力，將導軌的該圓弧狀斷面的曲率半徑形成得比進給推桿的半徑大。更詳言之，係將導軌的該圓弧狀斷面的曲率半徑形成得比進給推桿的半徑增大2%左右。另外，傳統的裝置構成中，為了使進給推桿支持在導軌上(偏靠導軌側的位置)接受導引，從進給推桿的長度方向軸線到導軌的圓弧狀斷面的曲率中心之距離，係設定在該圓弧狀斷面的曲率半徑的2%左右，例如，進給推桿為Φ50(半徑25mm)時，使導軌的圓弧狀斷面的曲率半徑為25.5mm，從進給推桿的長度方向軸線到導軌的圓弧狀斷面的曲率中心之距離為0.5mm(該圓弧狀斷面的曲率半徑的2%)。 Furthermore, in order to reduce the frictional resistance between the feed push rod and the guide rail, the radius of curvature of the arc-shaped cross section of the guide rail is formed larger than the radius of the feed push rod. More specifically, the radius of curvature of the arc-shaped section of the guide rail is formed to be about 2% larger than the radius of the feed push rod. In addition, in the conventional device configuration, in order to allow the feed push rod to be supported on the guide rail (a position close to the guide rail side) and receive guidance, the center of curvature from the longitudinal axis of the feed push rod to the arc-shaped section of the guide rail The distance between them is set at about 2% of the radius of curvature of the arc-shaped section. For example, when the feed push rod is Φ50 (radius 25mm), the radius of curvature of the arc-shaped section of the guide rail is 25.5mm, from The distance from the longitudinal axis of the feed push rod to the center of curvature of the arc-shaped section of the guide rail is 0.5mm (2% of the radius of curvature of the arc-shaped section).

如此的態樣，雖然進給推桿與導軌之間的間隙會設為摩擦阻力剛好可進行驅動的間隙，卻有進給推桿會振動而產生噪音之問題。 In such a configuration, although the gap between the feed push rod and the guide rail is set to a gap that is just enough for frictional resistance to drive, there is a problem that the feed push rod will vibrate and generate noise.

本案的發明人針對此問題深入研究探討，發現藉由在導軌的途中設置藉由進給推桿的下側側面而轉動(相對於進給推桿的下側面而滾轉)的下側導輥，可顯著地減輕進給推桿與導軌之間的摩擦阻力。並且，確 認了以該構成作為前提，即便使從進給推桿的長度方向軸線到導軌的圓弧狀斷面的曲率中心之距離極小(最理想的是距離為零)，也不會對進給推桿的驅動造成阻礙，同時也發現採用那樣的尺寸關係可顯著地抑制進給推桿的振動(關於導軌的圓弧狀斷面的曲率半徑，可相對於進給推桿的半徑留有一些裕度)。 The inventors of this case have conducted in-depth research on this problem and found that by setting the lower side guide rollers that are rotated by the lower side of the feed push rod (rolling relative to the lower side of the feed push rod) in the middle of the guide rail , can significantly reduce the frictional resistance between the feed push rod and the guide rail. and, indeed Considering this configuration as a premise, even if the distance from the longitudinal axis of the feed push rod to the center of curvature of the arc-shaped section of the guide rail is extremely small (the distance is ideally zero), the feed push rod will not be affected. At the same time, it is found that the vibration of the feed push rod can be significantly suppressed by adopting such a dimensional relationship (with regard to the radius of curvature of the arc-shaped section of the guide rail, some margin can be left relative to the radius of the feed push rod Spend).

本發明係根據以上的發現而創作完成的。本發明的目的在提供可減輕進給推桿的驅動阻力，且顯著地抑制進給推桿的振動之棒材供給機。 The present invention has been made based on the above findings. An object of the present invention is to provide a bar feeder capable of reducing the driving resistance of the feed ram and remarkably suppressing the vibration of the feed ram.

本發明係一種棒材供給機，係將棒材饋送到棒材加工機者，該棒材供給機具備有：朝棒材的軸線方向導引棒材之導引部；頂推前述棒材的後端部分以沿著前述導引部將前述棒材推送到棒材加工機之進給推桿；以及驅動前述進給推桿之驅動裝置；前述導引部係具有：配置成在與前述進給推桿的長度方向軸線平行的方向排成一列而延伸之複數個下側導軌元件；以及配置於鄰接的至少一組下側導軌元件之間，在前述棒材的推送之際藉由前述進給推桿的下側面而轉動之下側導輥；且各下側導軌元件的橫斷面而且是與前述進給推桿的長度方向軸線垂直的橫斷面，係具有：具有第一曲率中心及第一曲率半徑之圓弧狀部分；前述第一曲率中心係在前述進給推桿的長度方向軸線上，或從前述進給推桿的長度方向軸線偏離前述第一曲率半徑的1%以下的距離。 The present invention relates to a bar feeding machine which feeds the bar to a bar processing machine. The rear end part is used to push the aforementioned bar to the feed push rod of the bar processing machine along the aforementioned guide part; and the driving device for driving the aforementioned feed push rod; the aforementioned guide part has: A plurality of lower side guide rail elements arranged in a row in a direction parallel to the longitudinal axis of the push rod; and arranged between at least one set of adjacent lower side guide rail elements. The lower side guide roller is rotated for the lower side of the push rod; and the cross-section of each lower side guide rail element is also a cross-section perpendicular to the longitudinal axis of the aforementioned feed push rod, and has: a first center of curvature And the arc-shaped part of the first radius of curvature; the center of the first curvature is on the longitudinal axis of the aforementioned feed push rod, or deviates from the longitudinal axis of the aforementioned feed push rod by less than 1% of the aforementioned first radius of curvature distance.

根據本發明，設置藉由進給推桿的下側面而轉動(相對於進給推桿的下側面而滾轉)的下側導輥，可顯著地減輕進給推桿與導引部之間的 摩擦阻力，因此，即便使從進給推桿的長度方向軸線到導軌元件的橫斷面的圓弧狀部分的曲率中心之距離小到該曲率半徑的1%以下的距離也不會對於進給推桿的驅動造成阻礙，而且採用那樣的尺寸關係可顯著地抑制進給推桿的振動。 According to the present invention, the provision of lower side guide rollers that are rotated by the underside of the feed ram (rolling relative to the underside of the feed ram) significantly relieves the tension between the feed ram and the guide. of Therefore, even if the distance from the longitudinal axis of the feed push rod to the center of curvature of the arc-shaped part of the cross-section of the guide rail element is less than 1% of the radius of curvature, it will not affect the feed The drive of the push rod is hindered, and with that dimensional relationship the vibration of the feed push rod is significantly dampened.

較佳者為，前述下側導輥的通過轉動軸的橫斷面而且是與前述進給推桿的長度方向軸線垂直的橫斷面係具有：具有第二曲率中心及第二曲率半徑之圓弧狀部分；且前述下側導輥係定位於下側導引位置，其中，在該下側導引位置時，前述第二曲率中心在前述進給推桿的長度方向軸線上，或從前述進給推桿的長度方向軸線偏離前述第二曲率半徑的1%以下的距離。 Preferably, the cross-section passing through the rotating shaft of the above-mentioned lower side guide roller and the cross-section perpendicular to the longitudinal axis of the aforementioned feed push rod have: a circle with a second center of curvature and a second radius of curvature arc-shaped portion; and the aforementioned lower side guide roller is positioned at the lower side guiding position, wherein, at the lower side guiding position, the aforementioned second center of curvature is on the longitudinal axis of the aforementioned feed push rod, or from the aforementioned The lengthwise axis of the feed push rod deviates by a distance of less than 1% of the aforementioned second radius of curvature.

根據如此的構成，由於下側導輥的該圓弧狀部分的存在，在進給推桿的推送之際，下側導輥會用更廣的接觸區域接受來自進給推桿的下側面的轉動力(滾轉力)而滾轉，因而減輕進給推桿與導引部之間的摩擦阻力的效果會變得很高。 According to such a structure, due to the presence of the arc-shaped portion of the lower guide roller, when the feed push rod is pushed, the lower guide roller will receive pressure from the lower side of the feed push rod with a wider contact area. Rotational force (rolling force) causes rolling, so the effect of reducing the frictional resistance between the feed push rod and the guide portion becomes high.

或者，本發明係一種棒材供給機，係將棒材饋送到棒材加工機者，該棒材供給機係具備有：朝棒材的軸線方向導引棒材之導引部；頂推前述棒材的後端部分以沿著前述導引部將前述棒材推送到棒材加工機之進給推桿；以及驅動前述進給推桿之驅動裝置；前述導引部係具有：在前述棒材的推送之際藉由前述進給推桿的下側面而轉動之下側導輥；前述下側導輥的通過轉動軸的橫斷面而且是與前述進給推桿的長度方向軸線垂直的橫斷面，係具有：具有第二曲率中心及第二曲率半徑之圓弧狀部分；且前述下側導輥係定位於下側導引位置，其中，在該下側導引位置時，前述第二曲率 中心在前述進給推桿的長度方向軸線上，或從前述進給推桿的長度方向軸線偏離前述第二曲率半徑的1%以下的距離。 Alternatively, the present invention is a bar feeding machine for feeding a bar to a bar processing machine, and the bar feeding machine is provided with: a guide part for guiding the bar in the axial direction of the bar; The rear end part of the bar is used to push the aforementioned bar to the feed push rod of the bar processing machine along the aforementioned guide part; and the driving device for driving the aforementioned feed push rod; the aforementioned guide part has: When the material is pushed, the lower side guide roller is rotated by the lower side of the aforementioned feed push rod; the cross section of the aforementioned lower side guide roller passing through the rotation shaft is perpendicular to the longitudinal axis of the aforementioned feed push rod The cross section has: an arc-shaped portion having a second center of curvature and a second radius of curvature; and the aforementioned lower guide roller is positioned at the lower guiding position, wherein, at the lower guiding position, the aforementioned second curvature The center is on the longitudinal axis of the feed push rod, or deviates from the longitudinal axis of the feed push rod by a distance of less than 1% of the second radius of curvature.

根據本發明，由於下側導輥的該圓弧狀部分的存在，在進給推桿的推送之際，下側導輥會用更廣的接觸區域接受來自進給推桿的下側面之轉動力(滾轉力)而滾轉，因而減輕進給推桿與導引部之間的摩擦阻力的效果會變得很高。因此，即便使從進給推桿的長度方向軸線到該圓弧狀部分的曲率中心之距離小到該曲率半徑的1%以下的距離也不會對於進給推桿的驅動造成阻礙，而且採用那樣的尺寸關係可顯著地抑制進給推桿的振動。 According to the present invention, due to the existence of the arc-shaped portion of the lower guide roller, when the feed push rod is pushed, the lower guide roller will accept the rotation from the lower side of the feed push rod with a wider contact area. The power (rolling force) is used to roll, so the effect of reducing the frictional resistance between the feed push rod and the guide portion becomes high. Therefore, even if the distance from the longitudinal axis of the feed push rod to the center of curvature of the arc-shaped part is less than 1% of the radius of curvature, the drive of the feed push rod will not be hindered, and the use of Such a dimensional relationship significantly dampens the vibration of the feed ram.

在以上的各發明中，前述下側導輥配置成可從前述下側導引位置往下方側退避的話更佳。 In each of the above inventions, it is more preferable that the lower guide roller is disposed so as to be retractable downward from the lower guide position.

根據如此的構成，在將下側導輥設於由於加工的需要而棒材可能會轉動的區域之情況，可在棒材轉動之際使該下側導輥退避。因此，可防止下側導輥施加不希望有的轉動阻力(對於以軸線為中心的轉動之阻力)於棒材。 According to such a configuration, when the lower guide roller is provided in a region where the bar may turn due to processing, the lower guide roller can be retracted when the bar turns. Therefore, it is possible to prevent the lower side guide roller from exerting undesired rotational resistance (resistance to rotation around the axis) to the bar.

另外，前述導引部以更具有在前述棒材的推送之際藉由前述進給推桿的上側面而轉動之上側導輥較佳。 Moreover, it is preferable that the said guide part further has the upper side guide roller which rotates by the upper side surface of the said feed plunger at the time of pushing of the said bar material.

此情況，在進給推桿的推送之際，上側導輥會接受來自進給推桿的上側面之轉動力(滾轉力)而滾轉，因而會提高減輕進給推桿與導引部之間的摩擦阻力之效果。 In this case, when the feed push rod is pushed, the upper side guide roller will receive the rotational force (rolling force) from the upper side of the feed push rod and roll, thus improving the lightening of the feed push rod and the guide part.

根據如此的構成，由於上側導輥的該圓弧狀部分的存在，在進給推桿的推送之際，上側導輥會用更廣的接觸區域接受來自進給推桿的上側面之轉動力(滾轉力)而滾轉，因而減輕進給推桿與導引部之間的摩擦阻力的效果會變得很高。 According to such a structure, due to the presence of the arc-shaped portion of the upper guide roller, when the feed push rod is pushed, the upper guide roller receives the rotational force from the upper side of the feed push rod with a wider contact area. (rolling force) and roll, so the effect of reducing the frictional resistance between the feed push rod and the guide will become very high.

另外，在此情況，前述上側導輥配置成可從前述上側導引位置往上方側退避的話更佳。 Moreover, in this case, it is more preferable that the said upper side guide roller is arrange|positioned so that it can retract upward from the said upper side guide position.

根據如此的構成，在將上側導輥設於由於加工的需要而棒材可能會轉動的區域之情況，可在棒材轉動之際使該上側導輥退避。因此，可防止上側導輥施加不希望有的轉動阻力(對於以軸線為中心的轉動之阻力)於棒材。 According to such a configuration, when the upper guide roller is provided in a region where the bar may turn due to processing, the upper guide roller can be retracted when the bar turns. Therefore, it is possible to prevent the upper side guide roller from exerting undesired rotational resistance (resistance to rotation around the axis) to the bar.

另外，前述上側導輥以配置於所對應的前述下側導輥的上方而與該下側導輥成對較佳。 Moreover, it is preferable that the said upper side guide roller is arrange|positioned above the corresponding said lower side guide roller, and is paired with this lower side guide roller.

根據如此的構成，上側導輥與下側導輥將進給推桿夾在中間而導引該進給推桿，所以可進一步抑制進給推桿的振動。而且，可使上側導輥及下側導輥的控制指令為一樣的。 According to such a configuration, since the upper guide roller and the lower guide roller guide the feed ram while sandwiching the feed ram, the vibration of the feed ram can be further suppressed. Furthermore, the control commands for the upper guide roller and the lower guide roller can be made the same.

另外，在此情況，前述成對的前述上側導輥及前述下側導輥以配置成可變更該上側導輥與該下側導輥之間的間隔較佳。 In addition, in this case, it is preferable that the paired upper guide roller and the lower guide roller are arranged so that the distance between the upper guide roller and the lower guide roller can be changed.

根據如此的構成，可調整上側導輥與下側導輥將進給推桿夾在中間之際的保持力。 According to such a configuration, the holding force when the upper guide roller and the lower guide roller sandwich the feed plunger can be adjusted.

另外，前述導引部以隔著防振橡膠而支持於支持架較佳。 In addition, it is preferable that the said guide part is supported by the support frame through the anti-vibration rubber.

根據如此的構成，會防止在導引部產生的振動傳到支持架，所以可顯著地抑制噪音的產生。 According to such a structure, since the vibration generated in the guide part is prevented from being transmitted to the support frame, generation of noise can be significantly suppressed.

(退避動作之例) (Example of evasive action)

本實施型態的導引部30的比夾持裝置60要為前方(主軸側)的區域，有的情況前端部具有將加工中的棒材B的後方部分支持成可轉動的機能。本實施型態的可退避型的下側導輥裝置230及上側導輥裝置240係位於那樣的領域內。 In the guide part 30 of this embodiment, the front (spindle side) area of the clamping device 60 may have a function of supporting the rear part of the bar B being processed so as to be rotatable at the front end. The retractable lower guide roller device 230 and the upper guide roller device 240 of this embodiment are located in such a range.

不過，可退避型的下側導輥裝置230及上側導輥裝置240在升降缸239,249的作動下，下側導輥231可往下方側退避，上側導輥241可往上方側退避。因此，可防止下側導輥231及上側導輥241施加不希望有的轉動阻力(對於以軸線為中心的轉動之阻力)於棒材B。 However, the retractable lower guide roller device 230 and upper guide roller device 240 are operated by the lift cylinders 239, 249, the lower guide roller 231 can retract downward, and the upper guide roller 241 can retract upward. Therefore, it is possible to prevent the lower guide roller 231 and the upper guide roller 241 from applying undesired rotational resistance (resistance to rotation around the axis) to the rod B. As shown in FIG.

具體而言，如圖6(d)所示般棒材B變短之後，在比夾持裝置60要為前方(主軸側)的區域，仍然需要可退避型的下側導輥裝置230及上側導輥裝置240導引著進給推桿50。在此狀態，無需使下側導輥231及上側導輥241退避。 Specifically, after the bar B is shortened as shown in FIG. 6( d ), the retractable lower side guide roller device 230 and the upper side guide roller device 230 are still required in the area ahead (main shaft side) than the clamping device 60 . The guide roller device 240 guides the feed push rod 50 . In this state, it is not necessary to retreat the lower guide roller 231 and the upper guide roller 241 .

反之，如圖6(a)所示般棒材B還很長時，在三對可退避型的下側導輥裝置230及上側導輥裝置240，還是以藉由使升降缸239,249作動而使所有的下側導輥231及上側導輥241都退避較佳。 Conversely, when the bar B is still very long as shown in Figure 6(a), the lower guide roller device 230 and the upper guide roller device 240 of the three pairs of retractable type can still be moved by actuating the lifting cylinders 239, 249. It is preferable that all the lower guide rollers 231 and the upper guide rollers 241 retreat.

在棒材B為圖6(b)般的長度時，以形成為在前端側的兩對可退避型的下側導輥裝置230及上側導輥裝置240，使升降缸239,249作動而使該兩對下側導輥231及上側導輥241退避，只使剩餘的一對可退避型的下側導輥裝置230及上側導輥裝置240不退避之狀態較佳。 When the rod B has a length as shown in FIG. It is preferable to retract the lower guide roller 231 and the upper guide roller 241 without retracting only the remaining pair of retractable lower guide roller devices 230 and upper guide roller devices 240 .

在棒材B為圖6(c)般的長度時，以形成為在前端側的一對可退避型的下側導輥裝置230及上側導輥裝置240，使升降缸239,249作動而使該一對下側導輥231及上側導輥241退避，但不使其他的兩對可退避型的下側導輥裝置230及上側導輥裝置240退避之狀態較佳。 When the rod B has a length as shown in FIG. It is preferable to retreat the lower guide roller 231 and the upper guide roller 241 , but not retract the other two pairs of retractable lower guide roller devices 230 and upper guide roller devices 240 .

對應於涵蓋圖6(a)至圖6(d)之棒材B的長度的變化之可退避型的下側導輥裝置230及上側導輥裝置240的升降缸239,249的動作，以根據例如彈性爪夾52的位置資訊(例如彈性爪夾52往前方側/後方側通過該下側導輥裝置230及上側導輥裝置240的檢知資訊)來加以控制較佳。 Corresponding to the movement of the lifting cylinders 239, 249 of the retractable lower guide roller device 230 and the upper guide roller device 240 covering the change of the length of the bar B in Fig. 6(a) to Fig. 6(d), according to, for example, elastic It is better to control the position information of the claw clip 52 (for example, the detection information that the elastic claw clip 52 passes through the lower guide roller device 230 and the upper side guide roller device 240 toward the front side/rear side).
