Abstract

PURPOSE:To prevent the generation of falling sound and mutual colliding sound of pipes by providing vertical moving mechanism for moving an aligning base vertically within a range from a higher position than an arranging means to a height position close to the bottom face of a pipe receiver. CONSTITUTION:While pipes P supplied from a conveyor device 2 are arranged by an arranging means 11, an aligning base 121 stands by at a lower position than the arranging means 11. When the arrangement of these pipes P are completed, the aligning base 121 is moved upward into a higher position than the arranging means 11 so as to lift the pipes P in the arranged state from the arranging means 1. After lifting the pipes P by this aligning base 121, the aligning base 121 is moved horizontally into a position above a pipe receiver 3, and moved down into a height position close to the bottom face of the pipe receiver 3 so as to put the pipes down from the aligning base 121 and the load them onto the pipe receiver 3. The aligning base 121 is then moved back into its initial stand-by position to stand by.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pipe alignment device provided in a pipe packing line.

(Prior Art) In the final process of a pipe packing line, packed pipes are supplied from a conveyor such as a belt conveyor and loaded onto a forklift to be transported to a predetermined storage location.

By the way, if the forklift arm receives the pipe directly from the transport device, the pipe cannot be received from the transport device while the forklift is moving back and forth between the transport device and the storage location, so the packaging line must be temporarily stopped. Otherwise, the operating rate will decrease.

Therefore, generally, a pipe holder on which pipes can be loaded is provided at the end of the transport device, and the pipes loaded on the pipe holder are transported all at once by a forklift. Then, the pipes supplied from the transport device can be loaded onto the pipe receiver while the forklift is reciprocating between the transport device and the storage location, so there is no need to stop the packaging line.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional technology, in order to load pipes onto the pipe receiver, the bottom of the pipe receiver is installed lower than the height of the pipe being transported by the transport device. Therefore, the pipe will fall while being moved from the conveying device to the pipe receiver. Therefore, the sound of the pipe falling and the sound of the vibrators colliding with each other become a source of noise, and there is also a risk that the pipe will crack. Furthermore, since the pipes are loaded onto the pipe receiver in an irregular manner without being aligned, there is a problem in that it is necessary to bind the pipes with belts or the like to prevent the pipes from buckling when loaded onto the arm of a forklift.

The pipe alignment device of the present invention focuses on the above-mentioned conventional problems, and can move the pipes from the conveying device to the pipe receiver without dropping them, and can also align and stack the pipes inside the pipe receiver. The purpose is to do so.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and in order to achieve this purpose, the pipe alignment device of the present invention arranges the pipes in a predetermined manner. A pipe alignment device disposed between a conveying device that conveys pipes at intervals and a pipe receiver capable of loading pipes, the device receiving the pipes conveyed by the conveying device at the height at which they are conveyed. arranging means for arranging the pipes in a line by the arranging means, and a loading means for stacking and loading the pipes arranged by the arranging means in the pipe receiver, the loading means lifting the pipes arranged by the arranging means in an arrayed state. a horizontal movement mechanism capable of horizontally moving the alignment table within a range from a position substantially vertically overlapping with the arranging means to a position substantially vertically overlapping with the pipe receiver; and a vertical movement mechanism capable of vertical movement within a range from a higher position to a height position near the bottom surface of the pipe receiver.

(Function) The pipe alignment device of the present invention is disposed between a transport device that transports pipes at predetermined intervals and a pipe receiver that can load pipes.

Then, the pipes conveyed by the conveying device are first received by the arranging means at the height at which they are conveyed and arranged in a line, and then the pipes arranged by the arranging means are
Stack them in the pipe receiver using a loading means.

Therefore, the loading means includes a lining table capable of lifting the pipes arranged by the arranging means in an arrayed state, and a positioning table that moves the arranging table from a position substantially vertically overlapping with the arranging means to a position substantially vertically overlapping with the pipe receiver. a horizontal movement mechanism capable of horizontal movement within a range; and a vertical movement mechanism capable of vertical movement of the alignment table from a position higher than the arrangement means to a height position near the bottom surface of the pipe receiver. Therefore, the operation for stacking and placing pipes in the pipe receiver can be performed as follows.

While the pipes supplied from the conveyance device are being arranged by the arrangement means, the arrangement table is kept on standby at a position lower than the arrangement means. When the arrangement of the pipes is completed, the arrangement table is moved upward to a position higher than the arrangement means so that the arrangement table lifts the pipes from the arrangement means in the arrangement state. After lifting the pipes on the alignment stand, move the alignment stand horizontally to a position above the pipe receiver, and then move it downward to a height near the bottom of the pipe receiver, lower the pipe from the alignment stand, and place it above the pipe receiver. to be loaded. Then, the alignment table is again moved to the first standby position and is kept on standby. Thereafter, the above operation is repeated until a predetermined number of pipes are stacked and placed on the pipe receiver. From the second time onwards, after receiving the pipes on the arranging table, move the arranging table to the top surface of the pipes already loaded on the pipe holder. It will be moved downward to a nearby height position and the pipe will be lowered at that position.
