DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for forming a product into a final shipment package on a production line for producing products such as pipes, and more particularly to an apparatus for forming a package of a tubular product.

[0002]

2. Description of the Related Art Conventionally, when products such as tubes are shipped,
As shown in FIG. 6 to FIG. 8, an appropriate number of tubular articles 1 are arranged in parallel in one step and stacked in a plurality of steps, and a pair of step stacking auxiliary materials 2 are orthogonal to the tubular article 1 between the steps. It is interposed so that In addition, in order to increase the loading efficiency in a carrier such as a truck, the tubular article 1 is arranged with the receiving portion 1a and the insertion portion 1b alternately inverted, and the body portions of the adjacent tubular articles 1 abut each other. Let me. The step stacking auxiliary member 2 has stoppers 3 for locking the tubular article 1 on the upper and lower surfaces of both ends.

[0003]

In the above construction, the same auxiliary member 2 is used irrespective of the diameter of the tubular article 1, so that the tubular member disposed between the stoppers 3 of the auxiliary member 2 can be used. The number of articles 1 is not constant, and one stopper 3
In the state where the tubular article 1 contacts the other stopper 3, the tubular article 1 does not contact the other stopper 3.

[0004] To this end, the step stacking auxiliary material 2 is manually operated.
Are inclined at an appropriate angle with respect to the axis of the tubular article 1, and both the step-stacking auxiliary members 2 are arranged in a C-shape. However, human work is not always safe, the arrangement angle of the step stacking auxiliary member 2 is not constant, and all the stoppers 3 may not come into contact with the tubular article 1.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for forming a packing form of a tubular product, in which stoppers at both ends can reliably contact a pipe and a stacking aid can be arranged so as to prevent collapse of the load. .

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an apparatus for forming a shape of a tubular product in which a plurality of tubular products are stacked in an appropriate number of stages at a stacking station. An auxiliary material holding device for supplying a stacking auxiliary material between the stages, the auxiliary material holding device holding the stacked stacking auxiliary material rotatably around a vertical axis and ascending and descending, a stacking station and an auxiliary material A traveling vehicle that reciprocates on an elevated rail provided between the holding device and a traveling drive device that drives the traveling vehicle, a lifting frame that is provided on the traveling vehicle so as to be movable up and down, and a lifting drive device that drives the lifting frame. A rotating frame provided rotatably around a vertical axis on a lifting frame, and an air cylinder device for driving the rotating frame, and both sides of the rotating frame opposed to both ends in the axial direction of the stacking auxiliary member. A pair movable hand, those having a hand driving device for closer spacing both movable hand, and a sensor means for detecting the Danseki auxiliary material provided on both sides of the rotating frame.

[0007] In the above construction, the step stacking auxiliary member has a rectangular cross section and is provided with stoppers for locking the pipes on the upper and lower surfaces of both ends, so that the step stacking auxiliary member can be vertically stacked by being hindered by the stopper. Instead, the stacking auxiliary members are stacked with the arrangement direction being different in the direction perpendicular to the upper and lower stages.

In a state in which both end surfaces of the uppermost stacking auxiliary material stacked on the auxiliary material holding device are parallel to the traveling direction of the traveling vehicle, the traveling vehicle is located at an intermediate position between the stacking station and the auxiliary material holding device. The movable hands on both sides of the rotating frame are arranged at the same height position as both end surfaces of the uppermost stacking auxiliary member by raising the auxiliary member holding device while the standby position is maintained with the lifting frame raised.

In this state, the traveling carriage is driven, and the sensor means on both sides of the rotating frame detects the auxiliary stacking material located at the side end of the uppermost auxiliary stacking material. The movable hand is positioned with respect to both end faces of.

[0010] After driving the hand drive device to hold the stepping auxiliary material with both movable hands and lowering the auxiliary material holding device to secure the path of the traveling vehicle, the traveling vehicle moves the traveling material to remove the stepping auxiliary material. It is transported above the stacking station.

By lowering the elevating frame, the stacking auxiliary material is arranged on the uppermost tubular article of the stacking station at a position closer to one side of the tubular article, and the air cylinder device is driven to move the rotating frame. It rotates around the vertical axis, and the stoppers at the lower surfaces at both ends of the step-stacking auxiliary member abut against the tubular article.

At this time, since the stopper is pressed against the tubular article by the air pressure of the air cylinder device, the type and quantity of the tubular article, the manufacturing error of each tubular article, etc. are absorbed, and the tubular article is not damaged. It is possible to accurately position the step stacking auxiliary member with no excessive or insufficient force.

Thereafter, simultaneously with the release of the movable hand, the rotating frame is returned to the initial position, the lifting frame is raised, and the traveling carriage is returned to the intermediate position between the stacking station and the auxiliary material holding device.

Then, the above operation is repeated, and a stacking auxiliary member is disposed on the uppermost tubular article of the stacking station at a position closer to the other side of the tubular article, and contradicts the preceding stacking auxiliary material. In the direction, and arrange both the stacking aids in a C-shape.

Thereafter, the tubular articles stacked in the stacking station are lowered, a new one-stage tubular article is stacked on both of the auxiliary stacking materials by a separate device, and the above operation is repeated. To form a predetermined package.
