Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention, for example, rotates a roll around which a band-shaped packaging material such as a synthetic resin film is wound to tension the packaging material in order, and sequentially delivers the packaging material, which is supported at approximately the center of the orbit circle of the winding roll. The present invention relates to a movable guide device for supporting an object to be packaged in a packaging device that is wound around a tongue.

[0002]

[Prior Art]

 The strip-shaped wrapping material delivered from the winding roll in the above packaging device is wrapped around the article to be packaged together with the supporting guide that holds it, so that when the wrapping and packaging is completed, the packaged article is packaged. It is necessary to pull out the wrapped packaging material and the packaged items from the supporting guide when taking them out from the packing position. It is very difficult to take the packaging material out of the fork-shaped guide when it is pulled out from the fork-shaped guide, and it is very difficult. The object is also immobile, and therefore, the packaging material is spirally wound and wrapped over the entire length of the object to be packaged that is longer than the width of the strip-shaped packaging material, or is sequentially fed at appropriate intervals. It is not possible to wrap the wrapping material around the wrapping material in succession, and the wrapping material is continuously supplied on the fork-shaped guide with a gap, and the wrapping is completed. Was difficult to take out automatically.

It is to be noted that such disadvantages are solved, and it is easy to extract the strip-shaped wrapping material wound integrally with the article to be packaged and the guide for holding the article and the article to be packaged after the packaging is completed from the support guide. At the same time, the supporting guide is formed movably at a fixed value for packaging work, and the packaged object supported by this is continuously or intermittently moved for a long time with respect to a long packaged item. For example, it is possible to wind the strip-shaped packaging material in a spiral shape over the entire length of the packaging material, or to wind the packaging material continuously and continuously around an object to be packaged that moves continuously at an appropriate interval. For the purpose of improving the efficiency of packaging work, the two belt conveyors are superposed on each other so that both belts run at the same speed and in the opposite direction, and the upper belt surface of the two belt conveyors can be used for packaging. A guide support table on which a carriage is mounted and moved is disclosed in JP-A-57-861. It is disclosed as No. 0.

[0004]

[Problems to be solved by the device]

 In the conventional means described in the above publication, the packaging material is wrapped around the support table and the belt surface on the lower surface of the support table, and the packaging material is wrapped around the ends of the support table by the movement of both belts. The package is automatically taken out, but it has a significantly large thickness due to the presence of a fixed supporting plate supporting the belt or a roller supporting the lower surface of the belt due to the overlapping structure of the two belt conveyors. At the same time, each of the two belts requires a separate drive facility, and the means for ensuring that the running speeds of both belts are exactly the same, and the belt running is hindered by the wrapping of the packaging material, and the belt is damaged. There were defects such as easy occurrence.

[0005]

[Means for Solving the Problems]

 In order to eliminate the above-mentioned conventional defects, the present invention is a combination of a belt used and a small diameter trochanter group. The upper and lower surfaces of a base plate of a proper length erected substantially horizontally with one end free. A part of the endless belt along the upper surface, the belt along the upper surface toward the fixed base side of the base plate, and the belt on the lower surface toward the free end side of the base plate, and along the base plate. On the upper surface of the endless belt, a large number of small-diameter rolls are rotatably arranged side by side along the axis of the endless belt, and the rolls are brought into contact with the running belt on the upper surface of the base plate to make the lower surface of the base plate. A movable guide having an appropriate length is formed by frictionally rotating in the same direction as the endless belt along which the belt and the movable guide placed on the movable guide intersect in the length direction of the movable guide. It is characterized in that it is wrapped with a packaging material.

[0006]

[Action]

 The supporting movable guide (1) of the present invention constructed as described above is provided between the carry-in conveyor c and the carry-out conveyor d as shown in FIG. It is used as a support for work, and it is run continuously or intermittently for an appropriate period of time to move the object to be packaged a placed on its upper surface or while it is stationary, and the strip-shaped packaging material b and movable guide ( One that is wrapped around the lower surface of the belt (2) that composes (1) and packaged, and then runs the belt (2) of the guide (1) to take out the package a from the guide (1). At this time, the material to be packaged a is reliably transferred forward by the rotation of the small diameter roll (4), and the packaging material b wound around the belt (2) on the lower surface together with the material to be packaged a also has the smaller diameter on the upper surface. The lower belt (2) running at the same speed and in the same direction as the roll (4) moves toward the folded back free end (3a) of the belt to wrap it. It moves with the package a and finally separates from the free end (3a) and also the packaged product a is taken out from the movable guide (1). At this time, the packaging material separated from the plan (1). The winding portion b is contracted from the tensioned state and is tightly attached to the article a to be wrapped, so that the shape of the packaging is not lost due to the winding.
