Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for supplying tube materials to a forming machine that forms and loads tube materials into a predetermined shape in order to bundle a plurality of tube materials.

[Conventional technology]

When bundling a plurality of tube materials, a forming machine is used to shape the bundling into a predetermined shape for ease of handling. For example, when the cross section of the pipe material is circular, the forming machine usually has a hexagonal continuous three-sided groove-shaped shelf member, and a predetermined number of pipe materials are fed from the feeding device to each stage with their end surfaces aligned. They are supplied in a hexagonal configuration. After loading, they are bound by a binding machine.

Conventionally, even when the pipe material has a pipe joint at its end, the pipe material has been formed, stacked, and bundled with the end surfaces aligned.

[Problem to be solved by the invention]

However, when a pipe joint is provided at the end of the pipe material, if all the end surfaces of the pipe material are aligned as in the conventional method described above, the diameter of the pipe joint part is larger than that of the pipe part. The binding material becomes extremely large. Therefore, it is difficult to handle and requires a large space for storage. Furthermore, if even one of the bundles shifts in the longitudinal direction after binding, the binding may become loose and even create a dangerous situation. In addition, to prevent such situations,
The binding force must be extremely large to prevent slippage, but this will cause the tube to bend.

The present invention solves the problems that such conventional methods had, and enables compact and stable bundling.
The object of the present invention is to provide a method and device for supplying tube material to a molding machine.

[Means to solve the problem]

According to the present invention, the above-mentioned object relates to the method, from a standby part in which a plurality of pipes each having a pipe joint at the end thereof are placed in parallel to the longitudinal direction thereof, from a standby section substantially perpendicular to the longitudinal direction. Take out the above pipe material one by one in the correct direction,
In this method, a predetermined number of pipes are counted and then fed to the forming section to form and load them into a predetermined shape.In the process from the standby section to the forming section, every other pipe is loaded at least a distance equivalent to the length of the pipe joint. This is achieved by shifting the tube in the longitudinal direction.

In addition, the apparatus for carrying out the above method includes a standby part in which a plurality of pipes each having a pipe joint at the end are arranged parallel to the longitudinal direction thereof, and a standby part in which a plurality of pipes each having a pipe joint provided at the end are arranged in parallel to the longitudinal direction; a conveyance supply unit that takes out the tube materials one by one in the direction and conveys them while counting them by a predetermined number;
and a forming section that receives pipe materials from the conveyance and supply section and forms and loads the tube materials into a predetermined shape, the conveyance and supply section having at least a length corresponding to the length of the pipe fitting for every other tube being conveyed. This is achieved by providing a pusher that pushes the end face of the tube by a distance that

[Effect]

In the present invention, before the pipe materials taken out from the standby section reach the forming section, they are shifted in the longitudinal direction every other tube so that the pipe joint portions do not overlap.

As a result, the pipe materials are counted and supplied to the predetermined number of pipes at the positions where the pipe joint portion contacts the pipe portions of the front and rear pipe materials. The loading is thus extremely compact.

Further, according to the device of the present invention, the displacement of the tube material in the longitudinal direction is performed by a pusher. The pusher does not require complicated counting, and may simply be set to operate every other pusher.

〔Example〕

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a standby section, which is formed as a standby surface 2 whose upper surface has a slight slope downward to the right, and has a stopper surface 3 at its right end. In this way, the pipe materials P which have been subjected to final treatments such as anti-rust coating are brought one after another onto the waiting surface 2, and are arranged by rolling on the stopper surface 3 with the pipe end surfaces aligned.

On the right side of the standby section 1, a chain lifter 4 for transporting and supplying tube materials, a skid 5, and a forming section 8 are arranged in this order.

The chain lifter 4 has a plurality of lifts 12 at predetermined intervals.
It runs continuously in the direction of the arrow. A kick-in 13 is provided at a lower portion of the chain lifter 4 and rotates intermittently in the direction of arrow M. A free roller 14 is provided in the middle of the chain lifter 4, and the kick-in receives the tube material P taken out one by one from the standby section 1, and the tube material P on the free roller 14 is naturally moved by the lift 12 of the chain lifter. It is designed to be transported to

At a lateral position of the pipe material on the delivery member 14, a second
A pusher 15 is provided as clearly shown in the figure. The pusher 15 is configured to push the end face of the tube material every other time in the direction of the arrow N in synchronization with the operation of the delivery member 14, for example. The amount of pushing is equal to or greater than the length of the pipe joint portion P of the pipe material. In addition, in the case of a pipe material that does not have a pipe joint, the above-mentioned pusher may be set not to operate.

The skid 5 has a pool skid 6 and a slide skin door, and a retractable stopper 6A is provided between the two. The pool skin drawer is for pooling the tubing received from the chain lifter 4, and the slide skid 7 is for supplying a predetermined number of tubing to the forming section 8, and both have upper surfaces that are sloped slightly downward to the right. have. The stopper 6A comes and goes intermittently, but when the stopper 6A comes out and comes out, it comes out when a predetermined number of tubes for each stage to be supplied to the molding section are present on the slide skid 7, and the stopper 6A comes out and comes out so that more tubes than that are on the slide skid 7. It is set so that it does not occur. The slide skid 7 is designed to slowly move to the left when the predetermined number of slide skids 7 have been assembled.

The molding section 8 has a guide member 9, a stacker 10, and a movable guide member 11. The angle formed by the guide member 9 and the bottom of the stacker 10 and the angle formed by the side wall surface of the stacker -10 and the movable guide member 11 are all 120 degrees,
It forms the four sides of a regular hexagon.

The stacker 10 is movable up and down by a driver (not shown). A cart 17 having shelf portions 16 forming three sides of a regular hexagon is provided below the molding section 8 so as to be movable in a direction perpendicular to the plane of the drawing.

In the apparatus of this embodiment, the forming and loading of the tube material is carried out in the following manner.

(2) As shown in FIG. 2, the end faces of the pipes P on the delivery member 14 are pushed by the pusher 15 every other time, and the pipes P are moved in the longitudinal direction by at least one length of the pipe joint P.

(2) At this time, the free roller 14 moves the tube material P in the longitudinal direction without being rubbed or damaged. The tubing P is brought to the pool skid 6 by the chain lifter 4 and pooled there.

(2) The stopper 6A sinks downward and protrudes when a predetermined number of tubes have moved toward the slide skid 7, thereby preventing the subsequent transfer of the tubes. In the case of the illustrated regular hexagonal shape, the predetermined number is set to repeat a series of numerical values such as 3, 4, 5.43.

■ Next, for example, in the case of the first stage of pipe material in the forming section, when the three pipe materials are placed on the slide skid 7, the slide skid 7 moves to the left, and a receiver is placed at the bottom of the stanker 10. passed on. Then, the stunker 10 descends by a height corresponding to one stage. In this way, a predetermined number of books are loaded one after another in the second and third tiers. At this time, the movable guide member 11 serves as a stopper for objects above the central membrane, and does not fall to the right, forming the upper side of the hexagon.

(2) In this way, the pipes stacked in a regular hexagonal shape on the stacker 10 have their joints shifted in the longitudinal direction by the butchers 15, as described above.
It is loaded in an extremely compact shape. and,
The stacker 10 descends in this loaded state to the trolley 1.
7 Hand over to the above. The cart 17 moves in a direction perpendicular to the plane of the paper to the position of the binding machine, where the tubes are bundled and carried out.

〔Effect of the invention〕

As described above, in the method of the present invention, the pipe materials supplied to the molding machine are shifted every other pipe by the amount of the pipe joint, so the molded and loaded pipe materials are extremely compact, easy to handle after bundling, and easy to store. It takes up only a small space. Also, even if the tube material shifts in the longitudinal direction after binding,
There is no longer any danger due to the ties coming loose.

Further, according to the apparatus of the present invention, the above-mentioned forming and loading can be easily performed.
