(發明所欲解決之問題)(The problem to be solved by the invention)
於公知的縮徑加工中,當於縮徑加工之後使內側工具及外側工具自罐體脫離時,內側工具、底部工具及罐體成為一體以與該加工相反的順序相對於外側工具後退,首先使外側工具脫離罐體,然後使內側工具相對於底部工具後退,以使內側工具脫離罐體。
於上述加工方法中,若瓶罐等之縮徑加工之範圍為較長者,則縮徑步驟的時間增加。
於縮徑加工轉塔上進行縮徑加工之情況下,存在有為了增加縮徑步驟的時間而不得不增大轉塔的節距圓,進而造成設備大型化的問題。
此外,如圖1所示,通常具備有複數個縮徑加工轉塔101,且一面以搬送轉塔102依序搬送一面進行複數次之縮徑加工,於瓶罐等之口部細小之情況下,由於縮徑量亦變大,因此需要增加縮徑加工轉塔101的數量,隨著各縮徑加工轉塔101變大,則存在有設備整體更進一步變大的問題。In the well-known diameter reduction process, when the inner tool and the outer tool are detached from the can body after the diameter reduction process, the inner tool, the bottom tool and the can body are integrated and retracted relative to the outer tool in the reverse order of the process. Disengage the outer tool from the tank, and then retract the inner tool relative to the bottom tool to free the inner tool from the tank.
In the above processing method, if the diameter reduction processing range of bottles, cans, etc. is longer, the time for the diameter reduction step is increased.
When the diameter reduction process is performed on the diameter reduction processing turret, there is a problem that the pitch circle of the turret has to be increased in order to increase the time of the diameter reduction step, which results in an increase in the size of the equipment.
In addition, as shown in FIG. 1, there are usually a plurality of diameter

(Compared with the effect of previous technology)
根據本發明之罐體加工方法、及罐體加工裝置,於將內側工具及外側工具的相對位置固定之狀態下,使罐體及底部工具後退,將罐體自內側工具及外側工具拉出,藉此,可縮短縮徑步驟的時間,並且即使於範圍長且縮徑量大的縮徑加工中,也可於無需增大縮徑加工轉塔的節距圓或無需增加縮徑加工轉塔之數量的情況下進行應對,並且不用增大設備尺寸而可縮短加工時間。According to the can body processing method and the can body processing device of the present invention, the can body and the bottom tool are retracted while the relative positions of the inner tool and the outer tool are fixed, and the can body is pulled out from the inner tool and the outer tool, Thereby, the time of the diameter reduction step can be shortened, and even in the diameter reduction process with a long range and large diameter reduction, it is not necessary to increase the pitch circle of the diameter reduction processing turret or to increase the diameter reduction processing turret. It responds to the number of cases, and the processing time can be shortened without increasing the size of the equipment.
本發明之一實施形態之罐體加工裝置,為了將一端被開口的有底圓筒形狀之罐體K之開口部進行縮徑加工為瓶狀,例如,如圖1所示,將罐體K交接至複數個縮徑加工轉塔101及搬送轉塔102且在其等之間以依序進行加工之方式進行配置。
各縮徑加工轉塔101設置有複數個加工袋部103,各個加工袋部103在將所被交接的罐體K交接至下游之搬送轉塔102為止的期間進行縮徑加工。In the can processing device according to one embodiment of the present invention, in order to reduce the diameter of the opening of the bottomed cylindrical can K whose one end is opened into a bottle shape, for example, as shown in FIG. 1, the can K It is delivered to a plurality of diameter
如圖2所示,加工袋部103具備有:底部工具110,其支撐罐體K之底部;外側工具130,其與罐體K之開口部的外周部嵌合而進行縮徑;及內側工具120,其被***至罐體K之開口部。
於底部工具110設置有用以吸引保持罐體K之底部的吸引孔111。
底部工具110及內側工具120係構成為藉由驅動機構(未圖示)而分別獨立地可於罐體K之上下方向往復運動。As shown in FIG. 2, the processing bag portion 103 is provided with: a
如圖3所示,外側工具130係於其內表面具有導引罐體K之開口部的導入部131、提高罐體K之開口部之正圓度的直線部134、進行罐體之罐身部開口側之縮徑加工的縮徑部135及平坦(land)部132、及設於平坦部132之後部的逃逸部133。惟,直線部134並非必須,可配合需要適宜地被設置。
逃逸部133之相對於於平坦部132的徑向距離即逃逸量CL,被設定為0.07mm以上,更佳為0.13mm以上。
於逃逸量CL小於0.07mm之情況,當於縮徑加工後將罐體K拉出時,外側工具130及內側工具120與罐體K之摩擦阻力增大,存在有拉出不良的情況。
若逃逸量CL過大,則外側工具130之外徑增大,加工袋部103的節距增大,縮徑加工轉塔101之節距圓可能增大,因此亦可不要使逃逸量CL大於所需以上。As shown in Figure 3, the
在外側工具130之進退方向中的平坦部132之長度LL,被設定為1mm以上且10mm以下,更佳為5mm以下。
於平坦部132之長度LL小於1mm之情況,縮徑加工時與罐體K之接觸距離變短,存在有於開口端部產生褶皺的情況。
此外,於平坦部132之長度LL大於10mm之情況,縮徑加工後將罐體K拉出時之外側工具130及內側工具120與罐體K之摩擦阻力增大,存在有拉出不良的情況。The length LL of the
以下,對如上述之一實施形態的罐體加工裝置中的縮徑加工時之動作進行說明。
依照習知之罐體加工方法,首先,如圖5(a)所示,於內側工具120及外側工具130與底部工具110之間配置罐體K,該內側工具120及外側工具130係與罐體K之開口側對峙,該底部工具110係與罐體K之底面側對峙。
接著,於維持將外側工具130固定之狀態下,使內側工具120及底部工具110如箭頭所示朝罐體K行進,如圖5(b)所示,以底部工具110保持罐體K之底部且將內側工具120***至罐體K之開口部。Hereinafter, the operation at the time of diameter reduction processing in the can processing apparatus according to one of the above-mentioned embodiments will be described.
According to the conventional tank processing method, first, as shown in FIG. 5(a), the tank K is arranged between the
然後,於將罐體K、內側工具120及底部工具110的相對位置固定之狀態下朝外側工具130行進,如圖5(c)所示,藉由外側工具130自罐體K之開口部之外面實施縮徑加工。
當完成縮徑加工時,於將罐體K、內側工具120及底部工具110的相對位置固定之狀態下朝自外側工具130分離的方向行進,如圖5(d1)所示,將罐體K自外側工具130拉出。Then, while the relative positions of the tank K, the
最後,使內側工具120及底部工具110如箭頭所示朝遠離罐體K的方向行進,如圖5(d2)所示,將內側工具120自罐體K中拉出,釋放罐體K且移送至下一步驟。
Finally, make the
與此相對,根據本發明之罐體加工方法,首先,如圖4(a)所示,於內側工具120及外側工具130與底部工具110之間配置罐體K,該內側工具120及外側工具130係與罐體K之開口側對峙,底部工具110係與罐體K之底面側對峙。
In contrast, according to the can processing method of the present invention, first, as shown in FIG. 4(a), the can body K is arranged between the
接著,於維持將外側工具130固定之狀態下,使內側工具120及底部工具110如箭頭所示朝罐體K行進,如圖4(b)所示,以底部工具110保持罐體K之底部且將內側工具120***至罐體K之開口部。
Next, while maintaining the state of fixing the
然後,於維持將外側工具130固定之狀態下,並於維持將罐體K、內側工具120及底部工具110的相對位置固定之狀態下朝外側工具130行進,如圖4(c)所示,藉由外側工具130自罐體K之開口部之外面實施縮徑加工。此時,也可自供氣孔112朝罐體K供給壓縮空氣,使罐體K形成正壓以防止罐身部之彎曲。
Then, while maintaining the state of fixing the
迄此為止,與上述圖5所示者相同,但藉由本發明之罐體加工方法所進行的抽取,係於將內側工具120及外側工具130之相對位置固定的狀態下,使罐體K及底部工具110後退,如圖4(d)所示,藉由自內側工具120及外側工具130拉出罐體K,以一次動作釋放罐體K且將其移送至下一步驟。此時,藉由自供氣孔112朝罐體K供給壓縮空氣,減少於拉出所需的力,以抑制拉出不良。So far, it is the same as that shown in FIG. 5, but the extraction performed by the can processing method of the present invention is to fix the relative positions of the
因此,成為不需要圖5(d2)中的使內側工具120後退的動作,即使於縮徑加工之範圍長,縮徑量大的縮徑加工中,也可縮短加工時間而無需將設備大型化。
此外,於外側工具130之內表面具有導引罐體之開口部的導入部131、進行縮徑加工的縮徑部134及平坦部132、及設於平坦部之後部的逃逸部133,藉此,可確實地實施縮徑加工,並且減低自內側工具120及外側工具130拉出罐體K時的摩擦阻力,可以一次動作平滑地將罐體K拉出,並且由於可以減低拉出時之壓縮空氣的供給壓力,因此可降低運行成本。
此外,藉由對逃逸量CL及平坦部132的長度LL進行最佳化,可更可確實地實施縮徑加工,並且可以一次動作平滑地拉出罐體K。Therefore, the movement of retreating the
以上對本發明之較佳實施形態進行了說明,但本發明不限於上述實施形態。
例如,於上述說明之罐體加工方法中,外側工具130之位置於全步驟中皆被固定,但只要相對之移動相同,外側工具130也可進退。The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-mentioned embodiments.
