BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylinder aligning apparatus, and more particularly, to a cylinder aligning apparatus for aligning a plurality of cylinders with their axes aligned in parallel.

[0002]

2. Description of the Related Art When a long product such as paper or a plastic film is used as a roll product, a roll core is required. Such a roll has an L / D (length / diameter ratio) of about 5 to 20. A large number of cylindrical cores are used. Therefore, when such a core is mass-produced, the cores manufactured continuously from the core manufacturing apparatus are arranged in parallel with the cores and packed in cardboard boxes or the like in units of several hundreds before being shipped. . In such an operation, the core is conventionally manually packed in a cardboard box or the like, but this is inefficient and causes a decrease in productivity. Therefore, as an attempt to automate this packing operation, as shown in FIG. 8, the core 102 is sequentially shifted and dropped from the input port 101 which moves back and forth in the directions A and B.
A method has been adopted in which the cores are thrown into the cardboard box 103 or the like in the same axial direction. It was difficult to pack the core 102 into the core.
In addition, before packing in a cardboard box, if a predetermined number of cores can be aligned in a single row with their axes aligned in a row, and the aligned state can be maintained, the aligned cores are suctioned and transported in a aligned state by a suction device or the like. Then, it can be filled in a cardboard box or the like. For this purpose, a method has been considered in which the cores are arranged in parallel and conveyed by using a conveyor so that the cores are arranged in one stage. However, in the method of aligning cylindrical bodies using this conveyor, as shown in FIG.
04 is the stopper 1
05, the subsequent core 102 is
It is difficult to maintain one-stage alignment by being pushed up by the transport force of 4 and overlapping in multiple stages. Further, when the conveyor is provided, not only the equipment becomes large and the equipment cost becomes high, but also a problem arises that a space for installing the equipment is required. Further, when the inclined floor 106 is rolled down to align it on the floor in one step, the core 1
Due to the difference between the right and left frictional resistances of the core 102, as shown in FIG. 10A, the core 102 turns to the left and right ends on the floor surface 106 in the vertical direction, or As shown in the figure, there is also a problem that it is pressed in the traveling direction while being in the oblique direction, making it impossible to maintain the alignment state.

SUMMARY OF THE INVENTION According to the present invention, in order to arrange a plurality of cylindrical bodies in an aligned state in which the shaft cores are arranged in parallel, the cylindrical bodies are placed on an inclined surface without providing a large facility such as a conveyor. It is an object of the present invention to provide a device for rolling and dropping the rolls to align the shaft cores in parallel.

SUMMARY OF THE INVENTION The present invention relates to a tray which is arranged so as to be inclined so that a cylindrical body rolls down and travels, and a belt surface which is arranged on both sides of the tray and which has a vertical belt surface and a tray side. And a guide belt that travels in the direction of travel of the cylindrical body, and the guide belt travels at a higher speed than the speed at which the cylindrical body travels on the tray. Further, at least two protruding rails are provided in the inclined direction of the floor surface of the tray.

According to the above arrangement, when one end of a cylindrical body that advances obliquely on a tray that is inclined is brought into contact with the surface of the guide belt, one end of the cylindrical body that comes into contact with the surface of the guide belt is moved forward. The skew of the cylindrical body can be corrected and advanced, and the plurality of cylindrical bodies can be aligned on the tray with their axes aligned in parallel. In the cylinder skewed on the tray, the side with the higher frictional resistance remains behind and bends and skews toward the side with the higher frictional resistance, so that the cylindrical body always comes into contact with the guide belt on the side left behind.

An embodiment of the present invention will be described below with reference to the drawings.
