Description

The present invention is a device for a pipe accumulating device capable of sequentially accumulating pipes on a pallet without damaging the pipes manufactured and conveyed on the pipe making line.

Conventionally, pipes manufactured on a pipe making line move on a shooter with a slope, and when they reach the lower end, they are freely dropped onto a pallet installed below. At that time, in order to avoid damage to the pipes due to collision between pipes, it is necessary to take measures such as providing cushioning material in the pallet and adjusting by the operator, and moving the pallet itself up and down to shorten the fall distance. It was a major obstacle to automation.

The present invention includes a pipe supply device 101 that temporarily holds the transported plastic pipe P as shown in FIG. 6, a pipe integration carriage 102 placed on the side of the pipe supply device 101, and the pipe supply. It has a conveyor device 103 for transferring the plastic pipe P from the device 1 to the pipe stacking carriage 102. After the plastic pipe P conveyed to the pipe supply device 101 is held by the pipe mounting portion 111, when the moving piece 111b swings downward, it falls and is transferred onto the support stile 331 of the conveyor belt 133. Then, when the plastic pipe P descends to the lower end of the conveyor device 103, it falls from the support stile 331 and is sequentially integrated on the pipe accumulating carriage 102.

However, the configuration of the present invention is premised on the specifications of the pipe supply device 101, and cannot cope with the work of accumulating the pipes flowing on the shooter.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following embodiments. Further, it can be appropriately changed as long as it does not deviate from the range in which the effect of the present invention is exhibited.

FIG. 1 shows the arrangement of the pipe integrating device 1 and the upstream shooter 10 according to the present embodiment. A pipe manufactured on an upstream pipe making line (not shown) and cut to a predetermined size flows through a sloping shooter 10. The pipe integrating device 1 of the present application is arranged downstream thereof, and the pipe 50 staying in the shooter 10 is conveyed to the pallet 4 arranged below the device.

FIG. 2 shows a side view of the pipe integrating device 1. Several pipes 50 cut to a fixed size are arranged on the inclined metal shooter 10 while being restrained by the stopper 11 at the lower end. The rotating body 15 installed further downstream of the stopper 11 is formed in an axisymmetric shape and has four arm portions 16 for carrying the pipe. The number of arms is not limited to 4, and can be configured as 3 or 5.

The arm portion 16 rotates in a direction that separates the pipe 50 from the shooter 10, is restrained by the stopper 11, scoops one pipe stopped at the end end portion, and conveys it to the pipe accumulating device 1. As shown in FIG. 4, the recess for receiving the pipe formed in the arm portion 16 is designed to be compatible with a plurality of types of pipes produced in a pipe making line having a diameter of about 40 mm to 60 mm.

Further, the position of the stopper 11 is configured to move between the transport position and the stop position by the actuator 12 (an air cylinder is used in this embodiment). When the stopper 11 is pulled in and the pipe is moved to a stop position where it does not engage with the arm portion 16, the rotating body 15 is in a state of idling and the pipe is stopped. On the contrary, when the stopper 11 is extended in the direction of the elevating conveyor 2 and the pipe at the end is moved to the transport position where it engages with the arm portion 16, the pipe is conveyed to the elevating conveyor 2 by the arm portion 16. With this configuration, it is possible to stop the transportation of the pipe while the elevating conveyor 2 is operating.

The pipe scooped up by the arm portion 16 by the operation of the rotating body 15 and conveyed to the elevating conveyor 2 is placed on the pipe receiving portion 3. A dozen or more pipe receiving portions 3 are installed on the elevating conveyor 2 at equal intervals, and 14 pipe receiving portions 3 are provided in the present embodiment. This number is determined according to the total height of the elevating conveyor 2 which is determined according to the depth of the pallet 4.

In the present embodiment, the elevating conveyor 2 is configured such that a chain is hung over two sprockets fixed to the upper end and the lower end of the elevating conveyor main body, and one sprocket is driven by a motor (not shown). The pipe receiving portions 3 are fixed to the chain at regular intervals. Further, two or more elevating conveyors 2 are provided in the pipe axial direction, and a plurality of elevating conveyors 2 are configured to operate in the same manner, so that the pipes can be stably conveyed. In this embodiment, as shown in FIG. 1, four elevating conveyors 2 are provided so as to be able to handle pipes of various dimensions.

As shown in FIG. 4, the pipe receiving portion 3 on the side on which the pipe is placed has a U-shape with the edge portion facing upward so that the pipe does not fall off. The operating direction of the elevating conveyor 2 is determined so that the pipe receiving portion 3 on which the pipe is placed from the arm portion 16 moves downward. When the pipe receiving portion 3 on which the pipe is placed reaches the lower end of the elevating conveyor 2, the pipe receiving portion is inverted, and at the same time, the placed pipe falls off and is placed on the pallet 4.

The end of the arm 16 comes into contact with the lower surface of the pipe receiving portion 3 and is driven downward, and the rotating body 15 is driven counterclockwise. The installation interval of the pipe receiving portion 3 and the interval between the adjacent arm portions 16 are adjusted, and when the front arm portion 16 is separated from the lower surface of the pipe receiving portion 3, the next arm portion 16 becomes the next pipe receiving portion 3. It is configured to abut on the underside of the. In this way, the arm portion 16 is continuously driven by the elevating conveyor 2 and continues to convey the pipe to the elevating conveyor 2.

Further, in the present embodiment, the cam follower 17 is attached to the tip of the arm portion 16 of the rotating body 15. As a result, the driving resistance of the elevating conveyor 2 to the rotating body 15 can be reduced, the damage to the pipe receiving portion 3 due to the contact with the tip of the arm portion can be reduced, and the operating noise can be reduced.

Further, a sensor 5 is attached to the support portion 6 of the elevating conveyor 2 to detect the pipe placement status on the pallet 4. As shown in FIG. 3, the support portion 6 is located on the outside of the pallet 4 and supports the elevating conveyor 2 configured to move up and down in the pallet 4 via the bracket 7. Further, the support portion 6 and the elevating conveyor 2 are integrally configured to move in the vertical direction by a driving device (not shown) such as a motor.

The sensor 5 is installed slightly below the lower end of the elevating conveyor 2 of the support portion 6 and is set to detect obstacles in the horizontal direction. When the sensor 5 detects the pipe, the elevating conveyor 2 is controlled to move upward so as not to interfere with the pipe. In this embodiment, a laser sensor is used as the sensor 5.

When the sensor 5 reaches the position set as the pipe full position of the pallet 4, the stopper 11 moves to the stop position, the pipe transfer is stopped, and the pallet 4 is carried out. Then, when the next empty pallet is carried into a predetermined position and the elevating conveyor 2 moves to the lower part of the pallet, the stopper 11 moves to the transport position again and the pipe transport resumes.
