Description

[Detailed Description of the Invention] (Industrial field of application) The present invention sorts steel rods such as stacked steel pipes and rods into horizontal one-stage stacking by horizontally moving the rods in sequence. It relates to the device.

(Prior Art) In the drawn pipe manufacturing equipment, the present applicant proposes JP-A-61-145036 as a handling device that automates the pipe transportation between the facilities while preventing the occurrence of a handling eaves. This handling device is configured to receive and convey pipes in a single stage in parallel from the upper process to the lower process.

By the way, in the embodiment shown in FIG. 1 of JP-A-61-145036, the raw pipe is carried into the raw pipe carrying-in facility by a carrier, but the carrier is in a state in which the raw pipe is bundled. It comes from the upper process of hot pipe manufacturing plant and welded pipe manufacturing plant. Therefore, the bundled raw tubes are carried to the receiving and receiving table by the overhead crane, where they are artificially put into a single-stage stacking parallel state.

As an apparatus for forming a bundle of pipes and the like into a one-stage stacked parallel state, for example, Japanese Patent Laid-Open No. 58-63613 and Japanese Utility Model Laid-Open No. 57-111720.
There is a device disclosed in the publication.

However, each of these devices has a portion for receiving a bundle of pipes and the like, a portion for taking out the pipes and the like one by one from the portion and laterally feeding it, and a portion for receiving the pipes and the like that are fed one by one. Is a device for aligning pipes and the like while laterally feeding them. For this reason, a space for laterally feeding the pipe material is required, and the device itself has a large occupying area and becomes large-scale, and it is difficult to adopt it in the previous equipment for carrying in the raw pipe.

On the other hand, there is an apparatus disclosed in Japanese Utility Model Application Laid-Open No. 61-195822 as an apparatus for putting tubes placed in a bundle into a single-stage parallel state on the spot.

(Problems to be solved by the invention) However, although the device disclosed in Japanese Utility Model Laid-Open No. 61-195822 has a small occupied area, one end side of the pipe is rocked and pressed, and the alignment member is pressed while pressing the pipe. Since the pipes are moved in the long direction, the pipes are scratched due to the contact between the pipes while they are being pressed and the contact between each member and the pipe while being pressed. Further, in the case of a thin-walled pipe, there is a possibility that it may be dented or its cross-sectional shape may be elliptical.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an aligning device that occupies a small area of the device and can prevent the occurrence of flaws such as scratches.
