　以下、本発明の実施形態に係る開袋装置１を図１及び図２に基づいて詳細に説明する。
　図１及び図２を参照して、本発明の実施形態に係る開袋装置１は、物品（図示略）を袋体２内に包装する前工程にて、袋体２の開口端部３を開口するものである。また、本実施形態に係る開袋装置１は、袋体２の開口端部３を開口した後、袋体２を次工程の位置まで搬送するものである。 Hereinafter, a bag opening device 1 according to an embodiment of the present invention will be described in detail based on FIGS. 1 and 2.
Referring to FIGS. 1 and 2, a bag opening device 1 according to an embodiment of the present invention opens an open end 3 of a bag 2 in a pre-process of packaging an article (not shown) in a bag 2. It is an opening. Further, the bag opening device 1 according to the present embodiment is configured to transport the bag 2 to a position for the next process after opening the open end 3 of the bag 2.
　詳述すると、本実施形態に係る開袋装置１は、互いに独立して位置制御可能な多数のスライダ１１が基台１０に沿って移動自在に構成されるリニアコンベア４と、進行方向に沿って間隔を置いて配置される前後一対のスライダ１１、１１に設けられ、袋体２の開口端部３内に挿入される一対の支持部材５、５と、前後一対のスライダ１１、１１間の距離を制御することで、一対の支持部材５、５により袋体２の開口端部３を開口する制御装置６と、備えている。後で詳述するが、制御装置６は、特に、リニアコンベア４の各スライダ１１、１１の位置を、後述するリニアスケールを含む各種検出センサ（図示略）からの検出信号に基づき制御するものである。 To be more specific, the bag opening device 1 according to the present embodiment includes a linear conveyor 4 in which a large number of sliders 11 whose positions can be controlled independently of each other are movable along a base 10, and The distance between the pair of support members 5, 5 provided on the pair of front and rear sliders 11, 11 arranged at a distance and inserted into the open end 3 of the bag body 2, and the pair of front and rear sliders 11, 11. A control device 6 is provided which opens the open end 3 of the bag body 2 by controlling the pair of support members 5, 5. As will be described in detail later, the control device 6 particularly controls the position of each slider 11, 11 of the linear conveyor 4 based on detection signals from various detection sensors (not shown) including a linear scale described later. be.
　図１を参照して、リニアコンベア４は、リニアモータを駆動源として、基台１０上に敷設されたレールに沿って多数のスライダ１１、１１をそれぞれ移動させるものである。なお、リニアモータとしては、いわゆる可動磁石型リニアモータが適用される。この可動磁石型リニアモータは、具体的には、電磁石（電機子）がリニアモータ固定子として基台１０上に固定される一方、永久磁石がリニアモータ可動子として各スライダ１１に固定され、電磁石を構成するコイルへの電流供給が制御されることで各スライダ１１に推進力が与えられる。そして、各スライダ１１に固定されるスケールと、基台１０側に配置される複数のセンサと、を備えるリニアスケールが組み込まれる。このリニアスケールによる位置検出に基いて、前記コイルへの電流供給が制御されることで、特定位置への各スライダ１１の移動が可能となっている。要するに、リニアコンベア４では、制御装置６により、多数のスライダ１１、１１を、独立して、各スライダ１１の位置及び速度等を制御することができる。 Referring to FIG. 1, the linear conveyor 4 uses a linear motor as a drive source to move a large number of sliders 11, 11, respectively, along rails laid on a base 10. Note that a so-called moving magnet type linear motor is applied as the linear motor. Specifically, in this movable magnet type linear motor, an electromagnet (armature) is fixed on a base 10 as a linear motor stator, a permanent magnet is fixed on each slider 11 as a linear motor mover, and the electromagnet Propulsive force is given to each slider 11 by controlling the current supply to the coils that constitute the slider. Then, a linear scale including a scale fixed to each slider 11 and a plurality of sensors arranged on the base 10 side is incorporated. Based on the position detection by this linear scale, the current supply to the coils is controlled, thereby making it possible to move each slider 11 to a specific position. In short, in the linear conveyor 4, the control device 6 can independently control the position, speed, etc. of a large number of sliders 11, 11.

It is configured in an endless shape having an oval shape and consisting of a pair of linear portions 15, 15. In this embodiment, the base 10 has an endless shape with an oval outer shape when viewed from the side; however, the base 10 has an oval outer shape when viewed from above. It may be configured to be endless. A bag supply means 18 is disposed on the upper straight portion 15 of the linear conveyor 4 on the upstream side (left side in FIG. 1) in the conveyance direction. The direction in which the articles W are supplied by the bag supply means 18 coincides with the direction (width direction) orthogonal to the longitudinal direction of the linear portion 15 of the linear conveyor 4 . Although a detailed explanation of the specific configuration of the bag supplying means 18 will be omitted, the bag supply means 18 attracts the bag 2 and supplies it to a pair of support members 5, 5, which will be described later.
　図２を参照して、スライダ１１の上面には、脚部材２０が立設される。脚部材２０は、板材で構成される。脚部材２０は、リニアコンベア４の直線状部１５の幅方向からの矢視にてＬ字状に形成される。脚部材２０は、リニアコンベア４の直線状部１５の長手方向からの矢視にてＬ字状に形成される。脚部材２０には、軽量化にために複数の開口部２１が形成される。開口部２１は、リニアコンベア４の直線状部１５の長手方向に沿って貫通されている。脚部材２０の上端には、支持部材５が固定される。支持部材５は、断面略半円弧状に形成され、リニアコンベア４の直線状部１５の幅方向に沿って延びている。支持部材５の長手方向一端部が脚部材２０の上端に固定される。そして、進行方向に沿って間隔を置いて配置される前後一対のスライダ１１、１１に対応して、一対の支持部材５、５がその開放側が互いに対向するようにそれぞれ固定される。当該前後一対のスライダ１１、１１に対応する一対の支持部材５、５が、袋体２の開口端部３内に挿入される。 Referring to FIG. 2, leg members 20 are erected on the upper surface of the slider 11. The leg member 20 is made of a plate material. The leg member 20 is formed in an L-shape when viewed from the width direction of the linear portion 15 of the linear conveyor 4 . The leg member 20 is formed in an L-shape when viewed from the longitudinal direction of the linear portion 15 of the linear conveyor 4 . A plurality of openings 21 are formed in the leg member 20 for weight reduction. The opening 21 passes through the linear portion 15 of the linear conveyor 4 along the longitudinal direction. A support member 5 is fixed to the upper end of the leg member 20. The support member 5 has a substantially semicircular cross section and extends along the width direction of the straight portion 15 of the linear conveyor 4 . One longitudinal end of the support member 5 is fixed to the upper end of the leg member 20.
