Description

  The present invention provides a bag entrainment / suspending jig, particularly a plastic encasement / suspending jig that can easily and reliably lift a plastic bag containing waste without breaking the plastic bag.

  For example, the waste produced by the decontamination work is once put in a plastic bag, and then the plastic bag containing the waste is put into a pit and stored. In order to transport the plastic bag thrown into the pit to another place, since the plastic bag is piled up in the pit, it is taken out from the top in order and transported. At this time, since the waste includes high doses, it is necessary to take out the plastic bag from the pit without breaking the plastic bag.

  As a method of taking out the plastic bag from the pit, a method of lifting the part of the plastic bag in which the waste has been put between the gripping tools can be considered, but according to this method, the waste is sandwiched through the plastic bag. The possibility of tearing the plastic bag increases. In particular, when the waste is hard, there is a high possibility that the plastic bag will be torn.

  One embodiment of the bag wrapping jig according to the present invention will be described with reference to the drawings.

  FIG. 1 is a partially omitted front view showing a bag winding / suspending jig of the present invention, and FIG. 2 is a partially omitted side view showing a bag winding / suspending jig of the present invention.

  In FIG. 1 and FIG. 2, 1 is a hanging jig main body. A rod 1a is attached to the upper part of the hanging jig body 1, and the hanging jig body 1 can be moved manually. Reference numeral 2 denotes a driving roller attached horizontally to the lower part of the hanging jig body 1, and 3 denotes a driven roller attached to the lower part of the hanging jig body 1 in parallel with the driving roller 2.

  An upper portion of a later-described plastic bag (P) (see FIG. 3) in which the waste (M) is placed is lifted by being caught between the driving roller 2 and the driven roller 3. The bag to be lifted may be a bag other than a plastic bag. In this example, the surface of the drive roller 2 and the driven roller 3 is not uneven. However, if the surface of at least one of the drive roller 2 and the driven roller 3 is uneven, the drive roller 2 and the driven roller 3 and vinyl. Since the frictional force with the bag (P) is increased, the plastic bag (P) can be easily wound and the plastic bag (P) can be prevented from slipping when the plastic bag (P) is lifted. it can. The material of the driving roller 2 and the driven roller 3 is preferably urethane rubber because it is difficult to slip. If the rotational force of the driving roller 2 is transmitted to the driven roller 3 through a gear (not shown), the driving roller 2 and the driven roller 3 rotate integrally, so that the vinyl (P) driving roller 2 and The winding between the driven roller 3 and the driven roller 3 can be performed reliably.

  Reference numeral 4 denotes a rotation driving unit that rotates the driving roller 2. The rotation driving means 4 is fixed to a lifting / lowering means 5 attached to the hanging jig body 1, a rack 6 that is lifted / lowered by the lifting / lowering means 5, and a rotating shaft 7 that is engaged with the rack 6 and attached to the hanging jig body 1. The pinion 8 and the rotational force transmitting means 9 for transmitting the rotational force of the rotary shaft 7 to the drive roller 2 are included.

  The elevating means 5 is composed of a cylinder mechanism including a cylinder 10 and a piston 11, and is operated by air pressure or hydraulic pressure. The rack 6 is connected to the rod of the piston 11, and the rack 6 is raised and lowered by the elevating means 5. If air pressure is used as the cylinder mechanism, output adjustment can be easily performed, so that damage to the plastic bag (P) when the plastic bag (P) is lifted can be minimized.

  The rotational force transmitting means 9 transmits the rotational force of the driving pulley 12 fixed to the rotating shaft 7, the driven pulley 13 fixed to the shaft of the driving roller 2, and the driving pulley 12 to the driven pulley 13. It consists of a belt 14.

  According to the bag winding and suspending jig of the present invention configured as described above, the plastic bag (P) containing the waste (M) is lifted as follows.
