Description
本發明係關於一種具備有將罐蓋捲封至罐體的封罐輥的捲封裝置。The present invention relates to a crimping device provided with a can-sealing roller that crimps a can lid to a can body.
以往，具備有將罐蓋捲封至填充有飲料等之罐體的封罐輥的捲封裝置已為眾所周知。 已知有一種封罐輥，其具有：封罐輥銷，其於內部形成在上下方向延伸的潤滑劑通路，以使該封罐輥順利地旋轉；側周壁，其被設置為於，側周面形成捲封部，且經由軸承相對於上述封罐輥銷旋轉；及底壁，其將側周壁之底部封閉且與封罐輥銷之潤滑劑通路之開口相對向；且藉由自潤滑劑通路所被供給的潤滑劑對軸承進行潤滑。 軸承之潤滑亦兼具排出所產生之熱的作用，故而需要使潤滑劑充分地流動，因此一般藉由以加壓之方式供給潤滑劑而使潤滑劑流動，但是其存在有若潤滑劑之壓力增強，流量增加，則會導致潤滑劑自密封部分洩漏之虞。 又，於外部則需要有可確保所需之壓力與流量的潤滑劑供給機構。 在專利文獻1所示之例中，藉由將軸承空間部保持在加壓狀態，並且使潤滑劑進行噴霧，更進一步利用封罐輥之自轉作用作為泵，而強制性地使潤滑劑自封罐輥之軸承空間部排出至封罐輥外，藉此形成使潤滑劑始終在軸承空間部中循環的循環路徑。另一方面，其存在有若潤滑劑之壓力增強，流量增加，則會導致潤滑劑自密封部洩漏之虞。在專利文獻2所示之例中，提出有一種密封環及其潤滑裝置，其可同時地進行防止潤滑劑之洩漏與傳遞，並期求潤滑性之提昇。Conventionally, a crimping device equipped with a can sealing roller that crimps a can lid to a can body filled with beverages or the like has been known. There is known a can sealing roller, which has: a can sealing roller pin, which forms a lubricant passage extending in the up and down direction inside, so that the can sealing roller rotates smoothly; and a side peripheral wall, which is arranged on the side periphery. The surface forms a crimping portion, and rotates relative to the above-mentioned can sealing roller pin via a bearing; and a bottom wall, which closes the bottom of the side peripheral wall and is opposite to the opening of the lubricant passage of the can sealing roller pin; and through the self-lubricant The lubricant supplied from the passage lubricates the bearing. The lubrication of the bearing also has the function of dissipating the heat generated, so the lubricant needs to flow sufficiently. Therefore, the lubricant is generally supplied by pressurizing the lubricant to flow, but there is a pressure on the lubricant. If the flow rate increases, the lubricant may leak from the sealed part. In addition, an external lubricant supply mechanism that can ensure the required pressure and flow rate is required. In the example shown in Patent Document 1, the bearing space is kept in a pressurized state, the lubricant is sprayed, and the rotation of the sealing roller is used as a pump to force the lubricant to self-sealing. The bearing space part of the roller is discharged to the outside of the can sealing roller, thereby forming a circulation path for lubricant to always circulate in the bearing space part. On the other hand, if the pressure of the lubricant increases and the flow rate increases, the lubricant may leak from the sealing part. In the example shown in Patent Document 2, a seal ring and its lubricating device are proposed, which can simultaneously prevent leakage and transmission of lubricant and improve lubricity.
另外，在專利文獻3所示之例中，以如下之方式所構成：封罐輥銷12內之潤滑劑供油通路23(潤滑劑通路)係連通於封罐輥銷12所設的封罐輥8、9之軸承24的下方空間37，軸承24之上方空間38係藉由返回通路39連通至上述潤滑劑供油通路23而成為封閉迴路，被封入至封罐輥銷12、12內之潤滑劑供油通路23(潤滑劑通路)的潤滑劑係藉由離心力朝向外側流動至軸承24，其對軸承24進行潤滑之後，經由空間38、返回通路39返回至供油通路23(潤滑劑通路)，並再次被輸送至空間37，之後同樣地藉由離心力進行循環。 藉此，可省略外部之潤滑劑供給機構，從而抑制潤滑劑之洩漏。 [先前技術文獻] [專利文獻]In addition, in the example shown in Patent Document 3, the lubricant oil supply passage 23 (lubricant passage) in the can sealing roller pin 12 is connected to the can sealing roller pin 12. The space 37 below the bearing 24 of the rollers 8 and 9 and the space 38 above the bearing 24 are connected to the above-mentioned lubricant oil supply passage 23 through the return passage 39 to form a closed circuit and are enclosed in the sealing roller pins 12 and 12 The lubricant in the lubricant oil supply passage 23 (lubricant passage) flows outward to the bearing 24 by centrifugal force. After lubricating the bearing 24, it returns to the oil supply passage 23 (lubricant passage) through the space 38 and the return passage 39. ), and is transported to space 37 again, and then circulates similarly by centrifugal force. Thereby, an external lubricant supply mechanism can be omitted, thereby suppressing lubricant leakage. [Prior technical literature] [Patent Document]

The passage 457 then passes through the return lubricant passage in the roller swing shaft 132, returns to the inner casing of the machine, and is transported to the bearing 458 again. In addition, the lubricant may be any of oil, grease, water-soluble lubricant, etc., as long as it is a fluid.
以下對如上所構成之捲封裝置100之基本動作進行說明。 捲封罐蓋F之前的罐體C係卡合於搬入輸送帶102之各附屬件103而被搬送，且朝向藉由驅動機構151所被旋轉的封罐轉盤101。 另一方面，罐蓋F係自罐蓋分離單元210一片片地被切割送出，然後被傳遞至罐蓋搬送轉盤250之各凹槽P，並藉由罐蓋搬送轉盤250之旋轉，朝向封罐轉盤101(參照圖1)。 搬入輸送帶102、罐蓋搬送轉盤250之速度、其時序係以罐體C與罐蓋F之中心在合流點G一致之方式配合封罐轉盤101之速度、而調整時序，使從驅動機構151經由適當之齒輪、凸輪機構等而旋轉被控制的罐體載置單元350在合流點G上升，藉此將罐蓋F載置在被載置於平板360上的罐體C。 其後，罐體載置單元350更進一步上升，軋頭321內之頂出墊322壓住罐蓋F，並使從驅動機構151經由適當之齒輪、凸輪機構等而旋轉被控制的軋頭321嵌合至罐蓋F，並進行罐蓋F之中心校正，載置罐蓋F的罐體C利用於捲封所必要之既定的軸負載被平板360與軋頭321及頂出墊322所夾持。繼而，封罐轉盤101更進一步旋轉，於被夾持的罐蓋F與罐體C到達至於圖1所示之捲封區間E之前，平板360與軋頭321則加速至捲封所需之旋轉數。 於通過捲封區間E之過程中，使封罐單元410固定於輥擺動軸132之下端的捲封桿450擺動，並將分別樞接於兩端以便進行旋轉的1次捲封用、2次捲封用之2個封罐輥451、452自側方朝向軋頭321，依次壓抵於罐體C及被載置於其上部的罐蓋F之凸緣，從而進行雙重捲封。 捲封完成後之罐體CM係自封罐轉盤101被傳遞至出罐轉盤107，進而自出罐轉盤107被傳遞至搬出輸送帶108，並被搬出至檢查、包裝等之下一步驟。The basic operation of the winding and sealing device 100 configured as above will be described below. The can body C before the can lid F is rolled is engaged with each attachment 103 of the loading conveyor belt 102 and is conveyed toward the can sealing turntable 101 that is rotated by the drive mechanism 151 . On the other hand, the can lids F are cut and sent out piece by piece from the can lid separation unit 210, and then are transferred to each groove P of the can lid conveying turntable 250, and are moved toward can sealing by the rotation of the can lid conveying turntable 250. Turntable 101 (see Fig. 1). The speed and timing of the loading conveyor belt 102 and the can lid conveying turntable 250 are adjusted to match the speed of the can sealing turntable 101 in such a way that the centers of the can C and the can lid F coincide at the converging point G, so that the driven mechanism 151 The can placing unit 350 whose rotation is controlled through appropriate gears, cam mechanisms, etc. rises at the confluence point G, thereby placing the can lid F on the can C placed on the flat plate 360 . Thereafter, the can loading unit 350 further rises, and the ejection pad 322 in the rolling head 321 presses the can cover F, and causes the driving mechanism 151 to rotate the controlled rolling head 321 through appropriate gears, cam mechanisms, etc. It is fitted to the can lid F and the center of the can lid F is adjusted. The can body C on which the can lid F is placed is sandwiched between the flat plate 360, the rolling head 321 and the ejection pad 322 using the predetermined axial load necessary for crimping. hold. Then, the can sealing turntable 101 further rotates. Before the clamped can lid F and can body C reach the crimping section E shown in Figure 1, the flat plate 360 and the rolling head 321 accelerate to the rotation required for crimping. Count. During the process of passing through the sealing section E, the sealing rod 450 fixed to the lower end of the roller swing shaft 132 of the can sealing unit 410 is swung, and the sealing rod 450 is pivoted to both ends for rotation for primary sealing and secondary sealing. The two can sealing rollers 451 and 452 used for crimping are pressed from the side toward the rolling head 321, and are sequentially pressed against the can body C and the flange of the can lid F placed on the top thereof, thereby performing double crimping. After the sealing is completed, the can body CM is transferred from the self-sealing can carousel 101 to the can discharging carousel 107, and then is transferred from the can discharging carousel 107 to the unloading conveyor belt 108, and is moved out to the next step of inspection, packaging, etc.
