201002577 六、發明說明： 【發明所屬之技術領域】 本發明係關於在從袋的開口端部推入被包裝體來獲得 包裝品用之包裝裝置所使用的推送器。 【先前技術】 以往以來，使用推送器，對一端部呈封閉狀態、其相 反端部呈開口狀態之袋，推入被包裝體，然後，將呈該開 口狀態之端部作成爲封閉狀態來獲得包裝體之裝置爲眾所 皆知。例如在日本實開昭6 1 - 1 60002號公報（專利文獻1 )所記載的高速型包裝機械，藉由對筒狀的塑膠薄膜使用 複數個横封口機與切斷裝置，製作具有被熱封的封閉端部 與其相反端部之開口端部的袋。在該袋，使用推送器，推 入預定數量的被包裝體，然後，將開口端部予以熱封，獲 得包裝體。又，在這種的包裝機械，推送器的兩側部，預 先形成空氣吸引口，當一邊按壓被包裝體一邊進入到袋之 推送器從該袋退出時，從空氣吸引口吸引袋內部的空氣， 在袋的開口端部製作邊褶，將該開口端部予以熱封來作成 爲封閉狀態之技術，以往以來也爲眾所皆知。 〔專利文獻1〕日本實開昭6 1 - 1 60002號公報 【發明內容】 〔發明所欲解決之課題〕 在這種的先前技術，當推送器從袋退出時，袋的內部 -5- 201002577 容易變成減壓狀態。另外’當被包裝體爲用後即棄式的紙 尿褲、生理用衛生棉等的柔軟物、袋也爲以塑膠薄膜、紙 等的柔軟的薄片材料所形成者時，會有伴隨著成爲減壓狀 態之袋產生變形’被包裝體也會產生變形之情況產生。其 結果，會有被包裝體’其使用時之功能降低，或外觀變差 之情況產生。又’亦會有包裝體因成爲形狀不一致者，造 成在店面等不易排列整齊之問題產生。 又，在這種的以往技術’推送器前面部，爲了能以極 寬廣的面積按壓被包裝體，預先增大該面積爲佳D因此， 使一樣的按壓力作用於被包裝體的寬廣之面積的話，因使 用推送器造成被包裝體損傷之情況會變少。但，推送器的 前面部的面積變得越大，則袋的內面越會強力地密接於推 送器’即使吸引袋的內部的空氣，仿效推送器的溝槽地變 形一事也變得極爲困難。當成爲這種狀態時，則在袋迅速 地製作形狀一致之邊褶一事也變得困難。 因此，本發明之課題在於改良在包裝裝置所使用之推 送器，來解決被包裝體、包裝體所存在之上述問題。 〔用以解決課題之手段〕 在用以解決前述課題之本發明中，包含有第1發明與 第2發明。該第1發明之對象，爲在對具有封閉端部與其 相反端部之開口端部之袋，從前述開口端部推入被包裝體 後’一邊在前述開口端部的兩側形成邊褶，一邊封閉前述 開口端部’從前述袋與前述被包裝體獲得包裝體之包裝裝 -6- 201002577 置中所使用之用來推入前述被包裝體之推送器。 在該推送器，第1發明之特徵如以下所述。前述推送 器係爲朝推入前述被包裝體之方向和其相反方向進行往復 運動的推送器，包含有頭部分，該頭部分具有：一邊壓接 於前述被包裝體一邊進入到前述袋之前端部 '其相反端部 之後端部、及在前述前端部與前述後端部之間，朝推入前 述被包裝體之方向相互地平行延伸之兩側部。前述前端部 係具有：當前述前端部位於前述袋的內側時，可經由前述 推送器，將前述袋的內側與外側作成爲通氣狀態之空氣供 給口。前述兩側部係具有：當位於前述袋的內側之前述前 端部朝前述相反方向移動時，可在前述袋的前述開口端部 形成前述邊褶之空氣吸引口。 第1發明的實施形態之一，前述頭部分的前述前端部 之前述空氣供給口，在前述前端部與前述後端部之間、前 述後端部及較前述後端部更後方中的其中一者，開放成大 氣。 又，第1發明的實施形態之一，從前述頭部分的前述 前端部之前述空氣供給口，可對前述袋的內部供給加壓空 氣。 又，第1發明的實施形態之一，前述頭部分的前述兩 側部，分別具有從前述前端部朝前述後端部延伸之V字溝 ，在前述V字溝的底部，形成有前述空氣吸引口。 本發明之前述第2發明的對象，爲在對具有封閉端部 與其相反端部之開口端部之袋，從前述開口端部推入被包 201002577 裝體後，一邊 前述開口端部 裝裝置所使用 在該推送 送器係進行朝 相反方向的後 ，含有頭部分 邊進入到前述 向呈正交之寬 度方向呈正交 述厚度方向相 分割成第1板 的狀態中之其 兩側，形成有 述邊褶之V字 吸引源相連之 述第2板與前 體而進入到前 述被包裝體的 前述第2板與 述第1板一邊 述袋，一邊可 2、第3板中 面部位於前述 在前述開口端部的兩側形成邊措，一邊封閉 ，從前述袋與前述被包裝體獲得包裝體之包 的用來推入前述被包裝體之推送器。 此桌2發明之特徵如以下所述。前述推 推入前述被包裝體之方向的前進運動和朝其 退運動之往復運動的推送器，在前述推送器 ’該頭部分具有一邊壓接於前述被包裝體一 袋之前面部’並且具有與前述往復運動的方 度方向、和與前述往復運動的方向及前述寬 之厚度方向。前述頭部分係處於分割成在前 互重疊的第1板與第2板之2個板的狀態及 與夾持該第1板的第2板和第3板之3個板 中一狀態，在前述第1板的前述寬度方向的 朝前述往復運動之方向延伸並使用於形成前 形剖面之溝’並且’在前述溝形成有與真空 開口。以在前述推送器的前述前進運動，前 述第3板和前述第1板一同推入前述被包裝 述袋，在前述推送器的後退運動，當處於前 推入動作結束而前述第1板靜止的狀態時’ 前述第3板後退而從前述袋退出’然後’前 使來自於前述真空吸引源的真空壓作用於前 後退的方式形成則述頭部分。前述第1、弟 其中任一者之前述前面部係具有：當前述前 袋的內側時，經由前述第1板可將前述袋的 -8 - 201002577 內側與外側作成爲通氣狀態之空氣供給口。 第2發明的實施形態之一，前述第2板與前述第3板 係在前述頭部分的後方，形成爲一體。 又，第2發明的實施形態之一，從前述空氣供給口， 可對前述袋的內部供給加壓空氣。 〔發明效果〕 本發明中之第1發明的推送器，由於在其頭部分之前 端部具有空氣供給口，在兩側部具有空氣吸引口，故，當 頭部分結束被包裝體的推入而從袋退出時，即使從用來在 袋的開口端部形成邊褶之空氣吸引口吸入開口端部內側的 空氣，已被推入有被包裝體之袋中央部分也不易成爲減壓 狀態，可防止因形成邊褶所引起之被包裝體的變形。 本發明中之第2發明的推送器，由於其頭部分具有相 互重疊的第1板與第2板、或具有第1板與夾持該第1板 的第2板和第3板’當被包裝體的推入動作結束時，使第 2板、或第2板與第3板從袋退出後，僅使用第1板，來 在袋形成邊褶。因此’即使當推入被包裝體，袋密接於頭 部分’形成邊褶時之袋也不會密接於頭部分，故，即使第 1板之用來形成邊褶的溝很深，袋也容易進入到該溝而變 形成仿效溝的形狀，能夠迅速地獲得形狀一致之邊褶。 【實施方式】 以下’參照圖面’詳細地說明關於在包裝裝置所使用 -9 -

In Figure 10(b), After the head portion 136 advances and is pressed against substantially the entire portion of the portion I 9 of the assembly I5a, Pushing the assembly i 5a into the inside of the tunnel-shaped hopper 2 1 b, Then push it into the bag 2 b, The bag 2 b is detached from the hopper 21b. When the assembly 15 & When pushed into the bag 2b, A portion of the head portion 136 enters the bag 2b. In Figure 10 (c), The main board 1 5 1 is in a stationary state. In addition, The upper sub-plate 1 52 and the lower sub-plate 1 5 3 are moved by the sub-rod 1 38 and the sub-rod 1 3 9 to retreat and further withdraw from the open end 5 of the bag 2 b. When the upper sub-plate 1 5 2 and the lower sub-plate 1 5 3 start to retreat, a pair of suppression plates 31 are close to the bag 2b, The bag 2 b is suppressed from moving. In Figure 10(d), The main board 151 of Fig. 10(c) starts to retreat in order to exit from the bag 2b. In addition, A pair of suppression plates 31 are further adjacent to the bag 2b. Further, at the main plate 1 5 1 'sucking port 1 5 7 the inner air of the bag 2b starts to be sucked. The side surface portion 7 of the bag 2b is deformed into the shape of the emulation groove 156 in the vicinity of the opening end portion 5, Thereby, the side pleats 61 are formed (refer to Fig. 10 (f)) -20-201002577. The front part 1 5 1 a of the main board 1 5 1 is located on the inner side of the bag 2b, and the main board 1 5 1 Since the air supply port 158 (refer to Fig. 9) has been opened to the atmosphere, The inner side and the outer side of the bag 2b can be made ventilated, so that the main board 1 5 1 can be prevented. Sub board 1 5 2 The retracting action of 1 5 3 or the attraction of the suction port 157 of the main plate 151 causes the central portion of the bag 2b to become depressurized. With this, It is possible to prevent the aggregate 15 that has been pushed into the center portion from being deformed by the suction action. Furthermore, When the sanitary napkin contained in the individual package 3 has elastic compressive resilience, Aggregate 1 5 will be pressed when the current pusher is pressed. Being compressed and getting smaller, When the pusher 101 retreats, It is liberated from the compressed state and becomes larger in size. Although the bag 2b may become decompressed, but, By the pusher 101, there is an air supply port 1 5 8, It can be prevented from becoming the decompressed state. In Figure 10 (e), For the bag 2b after the main board 1 5 1 is withdrawn, A pair of heated sealing plates 3 2 are close to each other, Further, a heat seal portion 2e is formed at the opening end portion 5 (see Fig. 10(f)). Furthermore, Although not shown, After the back of the motherboard 151, Upper sub-plate 152 and lower plate 153, The position of these plates is automatically adjusted. Front portion 151a, 152a, 153a becomes the state shown in Fig. 8. Figure 10 (f) shows the package 14 obtained in the bagging process 13. In the package 14, Except for the heat seal portion 2d of Fig. 6, A heat seal portion 2e is also formed. The heat seal portion 2e' is in the up and down direction of the figure, It is formed substantially at the center of the end surface portion 62 of the package 14. At the side portion 7 of the bag 2 of the package 14, In the heat seal part 2 d, 2 e nearby, Forming edge pleats 6, 61. Furthermore, In Figure 10 (d), Forming the edge near the opening end 5 -21 - 201002577 When the pleats 6 1 , Also shown in Figure 9. The V-shaped groove 156 of the main plate 151 of the head portion 136 is formed with a suction port 157'. The bag 2b shown by the imaginary line is formed by the vacuum pressure applied through the suction port 157 to form the hem 6 1 . but, In Figure 1, 〇, After the sub-plate 1 5 2 and the lower sub-plate 1 53 are removed from the bag 2b, which is shown in FIG. Edge pleats 6 1 are formed. At the ditch 156 at this time, Vacuum pressure works, When the bag 2b is deformed in accordance with the groove 156, Up to now with the upper sub-board 152, When the lower sub-plate 153 is in contact and becomes a tension state, it becomes a relaxed state. This deformation is easily caused by the action of the bag 2b. therefore, At the pusher 101, Even when pushing into the assembly 15, The bag 2b is in close contact with the head portion 1 3 6, The side pleats 61 can also be easily obtained. in this way, According to this head part 1 3 6, Can achieve the following effects, which is, Will not cause damage to the aggregate 1 5a, The bag 2 can be deformed as an imaginary line along the groove 156. The effect of making the work of the side pleats 6 1 is easy. Such a head portion 〖3 6 is intended to make the opening angle α of the groove 1 5 6 of the main plate 1 5 1 extremely small, When the depth of the side pleats 6 1 formed by the main board 151 is extremely deep, Can improve the excellent effect. also, In the pusher 101 of the present invention, Even if it is used for the attraction of the bag 2 in the formation of the bag 2, Since the central portion of the bag 2 is open to the atmosphere via the air supply port 58 of the head portion 136, Therefore, It will not become a decompression state. therefore, Forming individual packages 3 of the assembly 15 It will not be deformed by the bag under pressure and will be distorted. also, Since the package 14 itself does not distort, Therefore, It is easy to bundle a plurality of individual packages 1 4 , Overlap when displaying. The air supply port for the function 1 5 8 is used for the air inlet port 5 5 except that it is disposed at the rear portion 1 5 1 b of the main -22-201002577 plate 1 5 1 as shown in FIG. It may also be disposed between the main front portion 1 51 a and the main rear portion 151b. Or it is placed at a position further rearward than the main rear portion 151b. also, Air intake 159, It can also be connected to a pressurized air supply source such as a compressor. It is used to supply pressurized air to the bag 2b. At the pusher 1 〇 1 , The beginning and end of the air attraction through the suction port 1 57, And the control of the start and end of the supply of pressurized air through the air supply port 158, A control mechanism (not shown) that controls these periods can be provided in the packaging device 110. Furthermore, At the pusher 101, It is also possible to replace the groove 1 5 6 of the illustrated example with a U-shaped groove, Other concave grooves and the like. also, At the pusher 1〇1, It is also possible to advance the upper sub-board 152, The lower sub-plate 1 53 is provided with an air supply port for the bag 2b, Can prevent these sub-boards 1 52, When the 1 53 is retracted, the bag 2b is in a decompressed state. Such an air supply port, It is not necessary to be set on the main board 151 as shown in the example. You can also consider the bag 2b and the assembly 1 5 The size of the head portion 1 3 6 , Set on the motherboard 1 5 1, Upper sub-board 1 52, Any of the lower sub-plates 1 53. In the present invention, The head portion 136 of the pusher 101, As shown in the example, Divided into 3 points' plate 151 having three sheets in the height direction T, 152, 153 are better. but, Upper sub-board 152 and lower sub-board 153, Alternatively, instead of being different from each other in the example of the figure, the head unit 136 may be connected to each other in the rear. Two boards 1 5 2 1 5 3 can advance at the same time, The way to go back. And, In the present invention, It is also possible not to use one of the upper sub-plate 1 5 2 or the lower 畐 ij plate 153, It is replaced with a head portion 136 which is divided into a thickness direction by a main plate 151 which is one piece and a sub plate 152 or 153 which is one piece. Fig. 1 is a view similar to Fig. 1(a) showing an example of the use of the pusher 1 〇 1 of the present invention - -23 - 201002577. The bag 2b of Fig. 11 has an open end portion 5 which is covered by the hopper 2lb. In addition, The closed end portion 4 enters the inside of the hopper 2B from the left of the machine direction A. The closed end portion 4 is in a state where its inner surface is exposed, and is opposed to the aggregate 15a. When the aggregate 15a is pushed by the pusher 1〇1 and enters the hopper 21b, It comes into contact with the inner face of the closed end portion 4 of the bag 2b. With the pusher 1〇1 advance, The aggregate 15a enters the bag 2b' and finally becomes the state of Fig. 1 (b). In order to cover the bag 2 b as the state of Fig. 11 with the open end 5 covering the hopper 2 1 b, Spraying pressurized air from the outside of the closed end portion 4 toward the bag 2b, The closed end portion 4 is brought into the hopper 2 1 b from the left side of the figure. In the form of Figure 11, When the pusher 101 is used to bring the assembly 15a into the bag 2b, In front of the aggregate 15a, The air is not sealed in the bag 2b' to obtain a compact package 14. Figure 12, 13 is a cross-sectional view of the same portion of FIG. 9 showing an example of the head portion 136 of the pusher 1〇1 of the present invention, And a perspective view of the package 14 obtained using the head portion 136. The head portion 1 3 6 of Fig. 12 is divided into two boards which are the main board 151 of the first board and the sub board 152 above the second board. After this head portion 136' is also withdrawn from the upper side plate 152 from the bag 2b, Using the groove 156 formed on the main board 151, A side pleat 61 is formed in the bag 2b. The bag 2b shown by the imaginary line in Fig. 12 shows the state in which the upper sub-plate 1 52 enters the bag 2b. The bag 2b' shown by the imaginary line shows that the upper sub-plate 1 5 2 exits and starts. The state when the side pleats 61 are formed. The package 14' obtained by using this head portion 136 is as shown in Fig. 13, The heat seal portion 2e formed in the end surface portion 62 of the bag 2 in the up and down direction of Fig. 13 is not located at the center of the end face -24 - 201002577 portion 62 but is located below the bottom portion. Such an end face 62, It is a large handle that is not ideal when the heat seal is divided into two equal parts at this position. The text is extremely ideal for use.
