Description

本発明は製品、特に円筒状製品をチエン式コンベアーで搬送する場合に該製品の転倒を防止するための転倒防止装置に関するものである。   The present invention relates to an overturn prevention device for preventing a product, particularly a cylindrical product, from being overturned when the product is conveyed by a chain conveyor.

径が大きく、長さが短い形状の円筒状製品を径方向を上下に幅方向又は径の横方向にチエン式コンベアーの受皿上に載せて連続的又は間欠的に搬送する場合、同円筒状の製品の慣性により転倒する場合がある。そのため通常、チエン式コンベアーは受皿の型状で転倒防止を図っているが、極端に径が大きく、長さが短い場合には搬送時における転倒を防止することは困難であり、このため転倒防止策が求められるが、未だ防止策については全く提案されていない。   When a cylindrical product with a large diameter and a short length is placed on the tray of a chain conveyor in the width direction or the diameter direction in the width direction or the width direction, it is transported continuously or intermittently. May fall due to product inertia. For this reason, the chain type conveyor is usually designed to prevent tipping by the shape of the saucer, but if the diameter is extremely large and the length is short, it is difficult to prevent tipping during transport. Measures are required, but no preventive measures have been proposed yet.

本発明は上述の如き実状に対処し、特にチエン式コンベアーに取り付けた受皿に下部より出没自在に該コンベアーの受皿と同調駆動する転倒防止バーの設置を見出すことにより円筒状製品をコンベアー受皿上で把持したまま搬送して製品の転倒，転がりを防止することを目的とするものである。   The present invention addresses the actual situation as described above. In particular, the cylindrical product is placed on the conveyor tray by finding the installation of a fall-preventing bar that is driven in synchronization with the tray of the conveyor so as to be able to protrude and retract from the lower portion of the tray attached to the chain conveyor. It is intended to prevent the product from falling or rolling by conveying it while holding it.

即ち、上記目的に適合する本発明の特徴は、先ず基本的に円筒状製品をチエン式コンベアーに取り付けた受皿上に載せて搬送する装置において、該コンベアー受皿下部より突出して円筒状製品を把持する転倒防止バーを設けたことにある。ここで、転倒防止バーはチエン式コンベアー受皿と同調して駆動されるものであることが効果的である。   That is, the feature of the present invention that meets the above-described purpose is that, first, in a device for carrying a cylindrical product on a tray attached to a chain conveyor, the cylindrical product protrudes from the lower part of the conveyor tray and grips the cylindrical product. There is a fall prevention bar. Here, it is effective that the fall prevention bar is driven in synchronization with the chain type conveyor tray.

請求項３は上記基本発明の転倒防止バーの具体的態様であり、チエン式コンベアー下部のエアシリンダーにより作動される昇降シャフト上部のラックに係合して開閉し、コンベアー下部より出没して製品を把持し、解除するストッパーローラ付きのストッパーアームであることを特徴とする。   Claim 3 is a specific embodiment of the overturn prevention bar of the basic invention, which is engaged with a rack at the upper part of the lifting shaft operated by the air cylinder at the lower part of the chain type conveyor, and opens and closes from the lower part of the conveyor to bring the product It is a stopper arm with a stopper roller for gripping and releasing.

請求項４，５は上記発明の具体的な応用形態で、請求項４は径方向を搬送方向に対し横方向に向けて横搬送する円筒状製品の前後より転倒防止バーを突出させて該製品を把持すること、また請求項５は径方向を搬送方向に向けて縦搬送する円筒状製品の左右両側より転倒防止バーを突出させて該製品を把持することを特徴とする。請求項６は上記発明の転倒防止バーの把持，解除をチエン式コンベアーの製品積込位置で突出させて円筒状製品を把持し、転送位置で製品の把持を解除し、転送することを特徴とする。   Claims 4 and 5 are specific applications of the above invention, and claim 4 is a product in which a fall prevention bar protrudes from the front and rear of a cylindrical product that is horizontally conveyed with its radial direction being transverse to the conveying direction. Further, according to a fifth aspect of the present invention, the product is gripped by projecting the fall prevention bars from the left and right sides of the cylindrical product which is vertically conveyed with the radial direction in the conveying direction. A sixth aspect of the present invention is characterized in that a cylindrical product is gripped by projecting at the product loading position of the chain conveyor, and the product is released from the transfer position and transferred. To do.

以上の本発明装置によれば、チエン式コンベアー受皿の下部に転倒防止バーを設け、これを該コンベアー受皿と同調駆動せしめているために円筒状製品をチエン式コンベアー上で搬送するとき同時に把持されて搬送され、従って、搬送時における円筒状製品の転倒又は転がりは阻止され、確実に、かつ安定して円筒状製品をコンベアー搬送することができる。   According to the above-described apparatus of the present invention, since the fall-prevention bar is provided at the lower part of the chain conveyor tray, and this is driven in synchronization with the conveyor tray, the cylindrical product is gripped at the same time when the cylindrical product is conveyed on the chain conveyor tray. Therefore, the cylindrical product is prevented from being overturned or rolled during conveyance, and the cylindrical product can be reliably and stably conveyed by the conveyor.

以下、添付図面を参照し、本発明の具体的実施形態について説明する。   Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

図１は、ウエブ巻取ロールの如き円筒状製品Ｒを受皿ブロック１ａからなるチエン式コンベアー１の受皿に、その径方向を矢示搬送方向に対し直交する方向に載せて横搬送する態様を示しており、搬送される円筒状製品Ｒの前後面側に夫々該製品Ｒを把持し、製品の転倒又は転がりを防止する転倒防止バー２がコンベアー受皿と同調駆動されるように設けられている。およそ、従来からチエン式コンベアー等の受皿にはこのような転倒防止バーを設けることは難しく、また受皿部に取り付け同調駆動することもできなかったが、本発明はこれを可能としているのである。   FIG. 1 shows a mode in which a cylindrical product R such as a web take-up roll is laterally transported on a tray of a chain conveyor 1 composed of a tray block 1a with its radial direction perpendicular to the direction of the arrow. In addition, an overturn prevention bar 2 that holds the products R on the front and rear surfaces of the cylindrical product R to be conveyed and prevents the products from overturning or rolling is provided so as to be driven in synchronization with the conveyor tray. In general, it has been difficult to provide such a fall-preventing bar on a tray such as a chain conveyor, and it has not been possible to attach it to the tray and drive it synchronously, but the present invention makes this possible.

即ち、転倒防止バー２は図２，図３に示す例にあってはチエン式コンベアー１の受皿１ａ下部より突出して円筒状製品Ｒの前後より把持する構成になっており、夫々ストッパーアーム３とその先端にストッパーローラ４を有して形成され、ストッパーアーム３の基端に夫々ラックギヤー５が軸着されていて、取付位置下部に固定されたエアシリンダー６より延びるロッド７により昇降する昇降シャフト８先端のラック９に係着されてその昇降により上記ストッパーアーム３及びアーム先端に取着されたストッパーローラ４がコンベアーの受皿ブロック間より突出し、あるいは没入し得るように構成されている。   That is, in the example shown in FIGS. 2 and 3, the overturn prevention bar 2 protrudes from the lower part of the tray 1 a of the chain conveyor 1 and is gripped from the front and rear of the cylindrical product R. A lift shaft which is formed with a stopper roller 4 at its tip, and a rack gear 5 is axially attached to the base end of the stopper arm 3 and is lifted and lowered by a rod 7 extending from an air cylinder 6 fixed at the lower part of the mounting position. The stopper arm 3 and the stopper roller 4 attached to the tip of the arm are engaged with the rack 9 at the tip of the 8 and moved up and down so that it can protrude or sink into the tray block of the conveyor.

なお、コンベアー１下部に固定して取り付けられた支持板１０と、昇降シャフト８下端との間にはロック用ばね１１が設けられており、ストッパーローラ４による把持時にはロックされ、ストッパーローラ４による把持の解除時にはエアシリンダー６のロッド７による突き上げによってロック用ばね１１は押圧され、ストッパーアーム３はストッパーローラ４と共に開きコンベアー１の下部に没入するようになっている。   A locking spring 11 is provided between the support plate 10 fixedly attached to the lower part of the conveyor 1 and the lower end of the elevating shaft 8 and is locked when gripped by the stopper roller 4 and gripped by the stopper roller 4. At the time of release, the lock spring 11 is pressed by pushing up the rod 7 of the air cylinder 6, and the stopper arm 3 is opened together with the stopper roller 4 so as to be immersed in the lower part of the conveyor 1.

図４は具体的に上記転倒防止バー２を用いて円筒状製品Ｒを転倒防止してコンベアー搬送する状況を示し、プーリＰ1，Ｐ2間に掛架され、エンドレスに回動するチエン式コンベアーの如きコンベアー１搬送において製品積込位置ａでストッパーローラ４による把持機構が作動して製品を把持した搬送が始まり、搬送が進行し転送する位置において把持解除が作動して一連の搬送が終了する。なお、上記各図における装置は、円筒状製品Ｒをコンベアー受皿上で径方向を横にして横搬送する場合であるが、円筒状製品Ｒはコンベアーに対してその径方向を平行にして縦搬送される場合もある。 FIG. 4 specifically shows a situation in which the cylindrical product R is prevented from falling using the above-described overturn prevention bar 2 and conveyed by the conveyor. The chain conveyor is suspended between pulleys P 1 and P 2 and rotates endlessly. In the conveyor 1 conveyance as described above, the gripping mechanism by the stopper roller 4 is operated at the product loading position a to start the conveyance of gripping the product, and the grip release is activated at the position where the conveyance advances and transfers, and the series of conveyance is completed. . In addition, although the apparatus in each said figure is a case where the cylindrical product R is horizontally conveyed on a conveyor tray with the radial direction being transverse, the cylindrical product R is vertically conveyed with its radial direction being parallel to the conveyor. Sometimes it is done.

図５はかかる縦搬送の態様を示し、チエン式コンベアー１により縦搬送れさる円筒状製品Ｒは該コンベアー１に図６（イ），（ロ）に示すように取付金具１２を介して取り付けられた受部１ｂに保持され、搬送方向においてその両側面より転倒防止バー２により把持されて搬送されている。この場合、転倒防止バー２の構造は実質的に前記横搬送におけると同様で、ストッパーアーム３と先端のストッパーローラ４により形成されており、ストッパーアーム３の基端にラックギヤー５が軸着されていて、エアシリンダー６のロッド７により押圧される昇降シャフト８上部のラック９に係着し、昇降シャフト８の上昇、下降に従って転倒防止バー２のストッパーローラ４が開閉し、搬送される円筒状物品Ｒをその両側より把持し、あるいは解除するようになっている。唯、縦搬送の場合は横搬送の円筒状製品Ｒの前後把持と異なり、両側面より把持するため転倒防止バー２はコンベアー１の両側より突出するように設けられる。そのため、縦搬送の場合は転倒防止バー２を図６の如く左右両側に夫々独立して設けらることが可能であり、ラック機構は夫々独立し、左右のストッパーローラ４も夫々単独で作動することができる。   FIG. 5 shows such a vertical conveyance mode, and the cylindrical product R conveyed vertically by the chain conveyor 1 is attached to the conveyor 1 via the mounting bracket 12 as shown in FIGS. 6 (a) and 6 (b). It is held by the receiving portion 1b and is held and conveyed by the fall prevention bar 2 from both side surfaces in the conveying direction. In this case, the structure of the overturn prevention bar 2 is substantially the same as that in the lateral conveyance, and is formed by the stopper arm 3 and the stopper roller 4 at the tip, and the rack gear 5 is pivotally attached to the base end of the stopper arm 3. The stopper roller 4 of the toppling prevention bar 2 is opened and closed as it is engaged with the rack 9 above the lifting shaft 8 that is pressed by the rod 7 of the air cylinder 6. The article R is grasped from both sides or released. However, in the case of vertical conveyance, unlike the front and rear gripping of the cylindrical product R for horizontal conveyance, the overturn prevention bar 2 is provided so as to protrude from both sides of the conveyor 1 in order to grasp from both side surfaces. Therefore, in the case of vertical conveyance, the overturn prevention bar 2 can be provided independently on both the left and right sides as shown in FIG. 6, the rack mechanisms are independent, and the left and right stopper rollers 4 operate independently. be able to.

以上のように本発明は搬送コンベアーに転倒防止バーが設けられ、しかも該バーはコンベアー受皿と同調して駆動されることから、円筒状製品の搬送において同製品を把持したまま転倒を防止して安定した搬送が可能となる。   As described above, according to the present invention, the conveyance conveyor is provided with the overturn prevention bar, and the bar is driven in synchronization with the conveyor tray, so that the conveyance of the cylindrical product can prevent the overturn while holding the product. Stable conveyance is possible.

本発明はウエブ巻取ロール製品の搬送の外、同様な各種円筒状製品の搬送に広く利用可能である。   The present invention can be widely used not only for transporting web winding roll products but also for transporting similar cylindrical products.
