Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shaping machine for bundling a plurality of elongated materials.

[Prior Art] A binding shaping machine is a device that shapes a bundle of a plurality of long materials into a round bar shape to facilitate bundling, in a pre-stage of binding a plurality of long materials. be.

For example, as shown in FIG. 4, a conventional binding shaping machine has two semicircular gripping members 10.11 at one end 101.
111 are rotatably connected by a support shaft 12, and the other ends of the gripping members 10 and 11 are connected to 102 and 112.
is connected to each air cylinder 13.4, and the air cylinder 1
3.14, it is configured to open and close around the support shaft 12.

E Problems to be Solved by the Present Invention] According to the configuration of the conventional binding shaping machine, when shaping a plurality of long materials A1 with the two gripping members 10 and 11,
A plurality of elongated materials A1 are placed inside with the upper end portions 102 and 112 of the gripping members opened, and the open upper end portions 102 and 112 of the gripping members 10 and 11 are moved in the closing direction. .

Therefore, the gripping members 10 and 11 that support the plurality of long materials A1 when moving in the closing direction are
．． There is a problem in that the amount of movement in each part of 11 is different, and the acting force applied to the plurality of elongated materials A1 is uneven, so that the bundle of the plurality of elongated materials A1 is not properly shaped into a round rod shape. Moreover, since the two gripping members 10 and 11 are forcibly moved in a direction against the weight of the plurality of elongated materials A1 to forcibly shape them, a large acting force is required.

In addition, there is a risk that the plurality of elongated materials A1 may be damaged at the contact portions with the gripping members 10 and 11. It has such drawbacks. Furthermore, even when a plurality of long materials are shaped for bundling, they do not become round bars, so they become loose after being bundled, making them difficult to handle and causing the load to crumble.

[Means for Solving the Problems] The present invention provides the following means for solving the above-mentioned conventional problems.

That is, the binding shaping machine of the present invention comprises an elastic cord that forms a single loop, a guide section that defines the position of at least the intersection of the loop, and a drive device that widens both ends of the elastic cord and makes the loop smaller. It is characterized by being configured to drive the driving device with a plurality of elongated materials placed in the loop to reduce the size of the loop and shape the elongated materials into a round rod shape. It is something.

With this configuration, a bundle of a plurality of elongated materials can be reliably, quickly, and effortlessly shaped into a round bar shape with a small acting force. Moreover, it is possible to shape a plurality of elongated materials into a shape that is easy to bundle.

The binding shaping machine of the present invention includes an elastic cord, a guide section, and a drive source as components.

The elastic cord has both ends and at least one
The other portions except for both ends are disposed within the guide portion.

Both ends of the elastic cord can be moved relative to each other via a loop, as will be described later, to widen or narrow the ends. One end of the elastic cord is fitted with a locking member outside the guide section, and is locked to the guide section when the loop is contracted. The other end is operatively connected to a drive device. The elastic cord can be moved by the drive device in a direction to make the loop smaller by widening the ends. Further, by narrowing both ends of the elastic rope by the driving device, the loop can be moved from the contracted position in a direction in which the loop is expanded. It is also possible to connect both ends of the elastic cord forming a single loop to a drive device.

In this case, the loop can be moved in the direction of making the loop smaller by simultaneously expanding both ends of the elastic cord using two drive devices. Furthermore, by simultaneously narrowing both ends of the elastic cord, the loop can be moved in a direction to make it smaller. In addition, elastic cords include elastic articles such as spring plates and wire cords, and rubber, plastic, etc. that cover the elastic members.
It may also be composed of a soft covering material such as leather. by this,
The elastic force of the elastic cord itself provides a force for returning the loop from the contracted position to the expanded position. In addition, when the loop formed by the elastic cord is contracted, the contact surface is soft (contacts with the plurality of long members of the elastic cord and does not damage the long members, and the durability of the elastic rope is It also improves.

The guide section is composed of a main body fixed to a base and a part of a cover attached to the main body, and is used to adjust the position of at least the intersection of the loops formed by the elastic cords. Further, the guide section can be configured to include a semicircular guide section at the upper part that defines the maximum diameter of the loop of the elastic rope, and a horizontal guide section at the lower part that guides the movement of the elastic rope in the horizontal direction.

The drive device is connected to one end of an elastic cord that makes a single loop, or in special cases double or more loops, and moves both ends of the elastic cord in a direction to widen it, thereby reducing the size of the loop. be. Also, move the both ends in a direction to narrow them,
The loop can also be made larger. Moreover, an air cylinder, a hydraulic cylinder, an electric motor, etc. can be used as the drive device. In addition, as a plurality of long materials, polished round steel bars, black rolled steel bars, steel pipes, synthetic resin bars, synthetic resin pipes, non-ferrous metal bars, metal pipes, lumber, etc. can be bundled and shaped.

[Operation] The elastic cord that forms the loop becomes larger as both ends of the elastic cord are narrowed by the drive device. A bundle of a plurality of long pieces of material is placed inside this loop. In this state,
When both ends of the elastic cord are widened by the driving device, the loop moves in a direction to make the loop smaller while the position of the intersection is defined by the guide. As a result, the loop shapes the plurality of elongated materials into a round rod shape.

[Effect] According to the binding shaping machine of the present invention, the loop is formed by the elastic cord that forms a single loop within the guide section and the drive device that moves in the direction of expanding both ends of the elastic cord and making the loop smaller.
Since the diameter is gradually reduced almost uniformly over the entire circumference, no stress is applied to multiple long materials. This allows the plurality of elongated materials to be reliably shaped into a round rod shape.

Therefore, when a plurality of long materials are bound together with wire, string, rope, etc. and then transported, the binding does not loosen or the load collapses due to changes in shape. In addition, it is easy to handle during transportation because it is tightly bound.

[Example] Examples of the binding shaping machine of the present invention are shown in Figs. 1, 2, and 3.
This will be explained based on the diagram.

The binding shaping machine of the embodiment includes an elastic cord 10, a guide section 20, and a driving device ajo.

A plate spring is used as the elastic cord 10. The elastic cord 10
except for both ends 103 and 104 are housed in a guide section 20 to be described later, and 111 loops 10 are placed in the center of the elastic cord 10.
At the same time, the intersection portion 102A of the loop 102 and the horizontal portion 101A of the elastic cord 10 are held by the guide portion 20. Additionally, one end 103 of the elastic cord 10 is fixed to a locking member 105 on the outside of the guide portion 20. Further, the other end 104 of the elastic cord 10 is also connected to a drive device 30, which will be described later, on the outside of the guide section 20.

The guide part 20 includes a main body 204 having a hole 201 in the center, a semicircular guide groove 202 at the upper part that becomes the inner peripheral wall of the hole 201, and a horizontal guide groove 203 at the lower part. and an inverted U-shaped guide cover 205 attached to the front surface of the guide cover 205. Main body 2 of the guide section 20
04 is attached to the base 50 with bolts 206 and nuts 207.

The drive device 30 can utilize a conventional air cylinder. The drive device 30 is mounted on a base 50.

The other end 1 of the elastic cord 10 with the loop 102 formed at the tip 302 of the piston rond 301 of the drive device 30
04 is caulked with a rivet 105.

The bundling shaping machine of the present invention configured as described above is used by disposing one on each side of a bundling machine C installed between a plurality of rollers B on a U-shaped conveyor. Next, the operation of the embodiment arranged in this manner will be explained.

For example, a plurality of long vJs 40 in units of 50 pieces are guided by eight U-shaped conveyors. One end of the elongated material 40 is passed through the binding shaping machine 1 and the binding machine C, and is guided and supported on rollers B. Also, at the same time, the long material 40
The other end is supported on a U-shaped conveyor A. As a result, the plurality of long materials 40 are positioned in the space within the loop 102 of the binding shaping machine 1, and in this state, the binding shaping machine 1
When the driving device [30 is operated, the other movable end 104 of the elastic cord 10 forming the loop 102 moves with respect to the fixed end 103. Intersection 1 of loop 102
02A gradually reduces the loop 102 while being guided by the horizontal guide groove 203 of the guide part 20, and shapes it into a round bar shape while tightening the long material 40 that contacts the plate elastic cord 10.

This completes the shaping of the plurality of elongated materials 40 into round rod shapes. At this point, the plurality of long materials 4° are bound by the binding machine C as in the conventional case. After the binding, the drive device 30 is operated again to move the elastic cord 10 in a direction that narrows both ends 103 and 104 of the elastic cord 10. At the same time, the elastic cord 10 enlarges the loop 102 by its own elastic action, and the semicircular guide groove 202 of the guide portion 20
It returns to the position where it abuts the peripheral wall, and prepares for the next shaping.

According to the present invention, a plurality of elongated materials can be reliably and quickly shaped into round bar shapes with an extremely simple configuration.

Moreover, a good shaping condition can be obtained by using a plurality of elongated materials with a small acting force. This makes it possible to easily perform the binding operation using the binding machine.

Further, since the plurality of long materials are not tied together and loosened, the load does not become loose. Also, since it is tightly bound, it is easier to transport and handle.
