Rolled. In addition, manual winding packaging and machine-wrapping packaging are known as means for packaging with the stretch film. The present invention relates to a stretch film hand-wound gripping tool used to wrap and wrap around an article to be packaged, and a wrapping operation tool using the gripping tool.

従来におけるストレッチフィルムを手巻き包装する操作具は数多く開示され、且つ市販やストレッチフィルムの販売促進品として提供されている。
特開平０８−１１９２４２号公報の発明 本願の図６〜図８に示す手巻き用ホルダー Many operating tools for manually winding and wrapping stretch films have been disclosed and provided as commercial products or sales promotion products for stretch films.
Invention of JP-A-08-119242 Hand-wound holder shown in FIGS.

上記特許文献1のストレッチフィルムの手巻き操作具は、その明細書に記載してあるように、ストレッチフィルムの巻き芯である紙管7内に挿通して使用する可操性のある材料で作った板状操作具1であって、紙管の一方の端面8の受部を有する第一ショルダー部3と他方の端面8の受部を有する第一ショルダー部3に連続するグリップ部5と、第二ショルダー部4に連続するハンドル部6とからなり、かつ紙管ホルダー部2と第一ショルダー部3とグリップ部5は紙管7内に挿通可能であり、第二ショルダー部4は紙管7の内径より幅広く、ハンドル部6は紙管ホルダー部2より短く、長さ方向端綾部に取手10を有している。前記ハンドル部3の幅方向側線部の少なくとも一方ストレッチフイルムカッター9を設けることができる、としている。   As described in the specification, the manual operation tool for the stretch film of Patent Document 1 is made of an operable material that is inserted into the paper tube 7 that is the core of the stretch film. A gripper 5 that is continuous with the first shoulder portion 3 having the receiving portion of the other end surface 8 and the first shoulder portion 3 having the receiving portion of the one end surface 8 of the paper tube. It consists of a handle portion 6 that is continuous with the second shoulder portion 4, and the paper tube holder portion 2, the first shoulder portion 3, and the grip portion 5 can be inserted into the paper tube 7, and the second shoulder portion 4 is a paper tube. The handle portion 6 is wider than the inner diameter of 7, and is shorter than the paper tube holder portion 2, and has a handle 10 at the end of the longitudinal direction. It is assumed that at least one stretch film cutter 9 in the width direction side line portion of the handle portion 3 can be provided.

上記特許文献1の使用に当たっては、ストレッチフィルムの紙管内に挿通したボードの上端部におけるグリップ管のフック孔に下端側に位置するハンドル部を折り返して端部の取手に連結したバンド先端のフックをグリップのフック孔に掛止し、そのグリップと取手を持ってほぼ垂直状態にして荷物の回りを巻き付ける。   In the use of the above-mentioned Patent Document 1, the hook at the end of the band connected to the handle of the end by folding the handle portion located at the lower end into the hook hole of the grip tube at the upper end of the board inserted into the paper tube of the stretch film. Hang on the hook hole of the grip, hold the grip and handle, make it almost vertical and wrap around the luggage.

次に、非特許文献２の手巻き用ホルダーは、包装・梱包資材関連のメーカーや販売会社により、インターネットのホームページで開示されている。   Next, the hand-wound holder of Non-Patent Document 2 is disclosed on a homepage on the Internet by a manufacturer / sales company related to packaging and packing materials.

そして、上記の非特許文献２の手巻き用ホルダーは、図６〜８に示すように、底部２１1の中心に手掛け用長孔２３を直径方向にあけた有底の円形の内筒２１と、これに回転自由に嵌合する円形の外筒２４から成り、これを２個一対として用い、外筒２２をストレッチフィルムのロール体Ｒの両端から芯材となる紙管Ｃ内にすっぽり挿入し、両手を内筒２１の手掛け用長孔２３に親指を除く４本の指全部を入れてロール体Ｒを持ち、ほぼ垂直状態にして荷物の回りを巻き付ける構成になっていて、「らく巻きホルダー」とも称されている。その際、親指は常にロール体に当てがっている。
これによって、ストレッチフィルムの横幅が５００ｍｍ、長さ３００ｍ程度で相当に重量があるロール体に簡単に装着ができ、上記のホルダーが軽量であるため軽くて疲れがない、とされている。 Then, Non-Patent Document 2 hand-winding holders described above, as shown in Figures 6-8, with a bottom spaced worked long hole 23 in the diameter direction in the center of the bottom portion 21 1 a circular inner cylinder 21 It consists of a circular outer cylinder 24 that freely fits on this, and uses these two as a pair, and the outer cylinder 22 is inserted completely into the paper tube C as the core material from both ends of the roll body R of the stretch film. Both hands are put into the long hole 23 for the inner cylinder 21 with all four fingers except the thumb and the roll body R is held in a substantially vertical state to wrap around the load. Is also called. At that time, the thumb is always placed on the roll body.
Accordingly, it is said that the stretch film can be easily attached to a roll body having a width of about 500 mm and a length of about 300 m, and has a considerable weight.

ところで、特許文献１のロール体の長さ(フィルムの幅に相当)方向の両端部付近を持った方がロール体を支受する力が分散して操作し易い。
その点、非特許文献２の手巻き用ホルダーは、ロール体の両端部位を持つ状態であるから、外筒がストレッチフィルムのロール体の内径が通常約７６ｍｍ（３インチ）の紙管内にすっぽりと挿入されているので、内筒とこれに嵌合する外筒厚さ（約５ｍｍ×２）を除く手掛け用長孔の長さ(約６６ｍｍ)その厚さ分を除いた結果である。成人作業者の親指を除く４本の指が楽に入る長穴を確保することができない。そのため、成人の作業者であると当該４本の手指全部を挿入することは困難である。また、仮に手指全部を挿入できるとしても第１関節までがせいぜいで楽で疲れずに安定して持つために必要な第２関節まで挿入することができない。そのため、人差し指か小指のいずれかを長孔から外したりして対応しているのが実状である。従って、紙管の内径が約６３ｍｍや約２５ｍｍの場合は、成人作業者の手掛けの長孔を確保できないため現実に非引用文献２のホルダーの適用は困難である。 By the way, the force of supporting the roll body is more easily dispersed and operated in the vicinity of both ends in the length (corresponding to the width of the film) direction of the roll body of Patent Document 1.
In that respect, the hand-wound holder of Non-Patent Document 2 is in a state having both end portions of the roll body, so that the outer cylinder is completely inside the paper tube whose inner diameter of the roll body of the stretch film is usually about 76 mm (3 inches). Since it is inserted, the length of the long hole for handle (about 66 mm) excluding the inner cylinder and the thickness of the outer cylinder fitted to this (about 5 mm × 2) is the result of removing the thickness. It is not possible to secure a slot for easy entry of four fingers except the thumb of an adult worker. Therefore, it is difficult for an adult worker to insert all four fingers. Moreover, even if all fingers can be inserted, the first joint required up to the first joint cannot be inserted up to the second joint, which is necessary in order to hold it comfortably and without fatigue. Therefore, the actual situation is that either the index finger or the little finger is removed from the long hole. Therefore, when the inner diameter of the paper tube is about 63 mm or about 25 mm, it is difficult to actually apply the holder of the non-cited document 2 because a long hole for a worker of an adult worker cannot be secured.

そこで、本考案は従来の課題を解決すると共に、本考案の目的を達成するために提供するものである。   Therefore, the present invention is provided to solve the conventional problems and to achieve the object of the present invention.

本考案の第１は、ストレッチフィルム手巻き用把持具において、有底円筒体の内径部に手掛け部を成形した円筒体を回転自在に結合し、且つ有底円筒体の底部の中心部にあけた孔にボルトを挿通してねじ部を底部外に突出固定して把持体を構成したものである。   A first aspect of the present invention is a stretch film manual winding gripper in which a cylindrical body formed with a handle portion is rotatably coupled to an inner diameter portion of a bottomed cylindrical body, and is opened at the center of the bottom portion of the bottomed cylindrical body. Bolts are inserted into the holes and the threaded portion is projected and fixed outside the bottom to constitute the gripping body.

本考案の第２は、ストレッチフィルム手巻き用把持具を用いた巻き掛け操作具において、有底円筒体の内径部に手掛け部を成形した円筒体を回転自在に結合し、且つ有底円筒体の底部の中心部にあけた孔にボルトを挿通してねじ部を底部外に突出固定して把持体を構成し、ロール巻きしたストレッチフィルムの紙管に挿通した筒軸体の両端部に設けたねじ部に連結固定するようにしたものである。   A second aspect of the present invention is a winding operation tool using a stretch film manual winding gripper, wherein a cylindrical body having a handle portion formed on an inner diameter portion of a bottomed cylindrical body is rotatably coupled, and a bottomed cylindrical body is provided. Bolts are inserted into the holes drilled in the center of the bottom part of the bottom, and the threaded part is protruded and fixed to the outside of the bottom part to form a gripping body, which is provided at both ends of the cylindrical shaft body that is inserted into the roll-wrapped stretch film paper tube. It is designed to be connected and fixed to the screw thread.

本考案の第３は、第１の発明及び第２の発明に係るストレッチフィルム手巻き用把持具を用いた巻き掛け操作具において、有底円筒体の底部の外面にストレッチフィルムの紙管の内径に嵌合する直径の環状凸条を成形したものである。   A third aspect of the present invention is the winding operation tool using the stretch film manual winding gripper according to the first and second inventions, wherein the inner diameter of the paper tube of the stretch film is formed on the outer surface of the bottom of the bottomed cylindrical body. An annular ridge having a diameter to be fitted into the shape is formed.

本考案は上記の構成であるから次の効果を有する。
（ア） 第１に、本発に係る把持具を用いると、ロール体の紙管の径が最大約７６ｍｍを基本とする場合、それより細い約６３ｍｍ又は２５ｍｍ程の細径のものであっても、有底円筒体の外底面をロール体の紙管内には挿入しないで、紙管両端面を押し付けて装着する構成であることにより、紙管の最大径（約７６ｍｍ）と同じ径か、それ以上の内径を有する手掛け部付き円筒体を用いることができ、成人作業者の親指を除く４本の手指が手掛け部内に挿入させることができ、作業の効率が図れる。
（イ） 第２に、ロール体の紙管の径を上記（ア）のようにサイズの異なる細い径の紙管であっても、常に最大径の紙管に用いる外径を有する把持体を用いることができる。従って、例えば直径約７６ｍｍの紙管に長さ３００ｍｍの超長尺のストレッチフィルムを約２５ｍｍの細径の紙管に同じ長さの同フィルムを巻いてローラー体を形成するとそのローラー体の外径を大幅に小さくすることができるので、在庫保管のスペースを少なくでき、且つ輸送コストを削減することができる。
（ウ） 第３に、本発明に係る把持具に係る把持具は、把持体を構成する有底円筒体と手掛け部付き円筒体が結合されていても、互いに自由に回転するので、使用のときに２個一対の有底円筒体が３００ｍもの超長尺のストレッチフィルムをロール巻きしたロール体の芯材となる紙管の中を挿通する筒軸体を介してそのロール体の紙管両端を押圧固定していても、手掛け部付き円筒体に対しては有底円筒が自由に回転できることにより、手掛け部付き円筒体を握って有底円筒体・紙管・ロール体を一体として回転させながら荷物にフィルムを巻き掛けることができる。
（エ） 第４に、ロール体の紙管両端に位置する有底円筒体が筒軸体両端にねじ結合することによって、その紙管両端面を適度の力で押圧固定しているので、ストレッチフィルムの紙管の板厚が薄くても最後まで使える。
（オ） 第５に、紙管内に挿通する筒軸体は、当該紙管の両端に配置する把持体を連結固定できれば良いのでその径を細くし、軽量に作ることができる。
（カ） 第６に、紙管の板厚を薄くしたり、または紙管自体の無いストレッチフィルムのロール体にも使用が可能であるから、紙管コストを節減できる。
（キ） 第７に、現在は紙管を持って作業するので紙管の強度が必要であるが、本発明の把持具を用いれば筒軸体の使用と相まって当該紙管の板厚を極端に薄くすることも可能であるから、使用済み後のボール紙製紙管の廃棄物が極力減少するので環境に優しい。 Since the present invention has the above configuration, it has the following effects.
(A) First, when the gripping tool according to the present invention is used, when the diameter of the paper tube of the roll body is basically about 76 mm at the maximum, the diameter is about 63 mm or about 25 mm, which is thinner than that. However, the outer bottom surface of the bottomed cylindrical body is not inserted into the paper tube of the roll body, and is the same diameter as the maximum diameter (about 76 mm) of the paper tube, because the both ends of the paper tube are pressed and mounted. A cylindrical body with a handle portion having an inner diameter larger than that can be used, and four fingers other than the thumb of an adult worker can be inserted into the handle portion, so that work efficiency can be improved.
(B) Secondly, even if the diameter of the paper tube of the roll body is a thin paper tube having a different size as in (a) above, a gripping body having an outer diameter that is always used for the maximum diameter paper tube is used. Can be used. Therefore, for example, when a roller body is formed by winding a super-long stretch film of 300 mm in a paper tube having a diameter of about 76 mm and winding the same length of the same film around a paper tube having a small diameter of about 25 mm, the outer diameter of the roller body Therefore, the inventory storage space can be reduced and the transportation cost can be reduced.
(C) Thirdly, the gripping tool according to the gripping tool according to the present invention rotates freely even if the bottomed cylindrical body and the cylindrical body with the handle portion constituting the gripping body are combined. Sometimes two pairs of bottomed cylinders are inserted into both ends of a paper tube through a cylindrical shaft that passes through a paper tube that becomes the core material of a roll of rolls of ultra-long stretch film of 300 m. The bottomed cylinder can rotate freely with respect to the cylinder with the handle even if it is pressed and fixed, and the bottomed cylinder, paper tube, and roll body can be rotated as a unit by grasping the cylinder with the handle. You can wrap a film around your luggage.
(D) Fourth, the bottomed cylinders located at both ends of the paper tube of the roll body are screwed to both ends of the cylindrical shaft body, so that both ends of the paper tube are pressed and fixed with an appropriate force. It can be used to the end even if the paper tube is thin.
(E) Fifthly, since the cylindrical shaft body inserted into the paper tube only needs to be able to connect and fix the gripping bodies disposed at both ends of the paper tube, the diameter thereof can be made thin and light.
(F) Sixth, since the thickness of the paper tube can be reduced, or it can be used for a roll body of a stretch film without the paper tube itself, the paper tube cost can be reduced.
(G) Seventh, since the paper tube is currently used to work, the strength of the paper tube is necessary. However, if the gripping tool of the present invention is used, the thickness of the paper tube is extremely reduced in combination with the use of the cylindrical shaft body. It is also possible to make it thinner, so the waste of used paperboard tube is reduced as much as possible.

本考案を実施するための最良の形態は次のとおりである。
まず、あらかじめ、２個一対の把持体と芯材となる紙管にロール巻きされているストレッチフィルム体の長さに合わせてある連結用軸筒軸体を用意しておき、当該筒軸体の一端に設けてあるねじ部に有底円筒体のボルトをねじ込んで結合し、次に筒軸体をロール体の一端からストレッチフィルム体の紙管に挿入した後、当該筒軸体の他端のねじ部に残りの１個の把持体の有底円筒体のボルトをねじ込んで結合し、両把持体の底部をストレッチフィルム体の紙管端面に圧接しておく。この状態において、有底円筒体はボルトの結合によって、紙管を介してロール体側に強固に固着しているが、有底円筒体に結合している手掛け部付き円筒体は自由に回転できる。そこで、作業者は両把持体の手掛け部に手指を掛けてロール体を略垂直に持って目的の被包装物に巻き掛けて包装する。この状態において、手掛け部に挿入していない親指を適宜に有底円筒体の外周面に押し当ててブレーキを掛けて張力調節しながら巻き掛け作業を行う。 The best mode for carrying out the present invention is as follows.
First, a connecting shaft cylinder shaft body is prepared in advance according to the length of a stretch film body rolled around a pair of gripping bodies and a paper tube as a core material. After screwing the bolt of the bottomed cylindrical body into the threaded portion provided at one end and then inserting the cylindrical shaft body into the paper tube of the stretch film body from one end of the roll body, The bolts of the bottomed cylindrical body of the remaining one gripping body are screwed into the threaded portion, and the bottoms of both gripping bodies are pressed against the end face of the paper tube of the stretch film body. In this state, the bottomed cylindrical body is firmly fixed to the roll body side via the paper tube by the coupling of the bolts, but the cylinder with the handle portion connected to the bottomed cylindrical body can freely rotate. Therefore, the operator puts his / her fingers on the handle portions of both gripping bodies, holds the roll body substantially vertically, wraps around the target article to be packaged, and packages. In this state, the wrapping operation is performed while adjusting the tension by pressing the thumb that is not inserted into the handle portion against the outer peripheral surface of the bottomed cylindrical body and applying the brake.
