Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a banding machine that can easily and quickly attach a band to a coil.

The strip coils wound with a winding machine are bound with a band to prevent them from coming apart, and a banding machine is used to wind the band.

A conventional banding machine will be described with reference to FIGS. 1 and 2. A frame b has a through-hole part a and is open at the bottom, and an arm d that can be swung by a fluid pressure cylinder C. A strapping head e equipped with a band feeding mechanism is attached to the tip of the arm d, and a strap chute f is attached along the arm d.

In addition, a strap chute g divided into a plurality of parts is arranged at a predetermined position of the frame b so as to surround the penetrating hollow part a, and is moved forward and backward by a fluid pressure cylinder h at the bottom of the frame b, and is connected to the front and rear strap chutes g when in use. Install a strap chute i to be used.

The strap chute fy g* 1 has a hollow gutter-like cross section, and on the side facing the penetrating hollow part a is a lid j that opens by the pressing force of the band B and closes when the band B is squeezed out to the outside of the strap chute. Install.

In the figure, a dispenser is provided with a mechanism for sending the band B to the strapping head e, and 1 is a coil car or skid on which a coil C is placed.

When wrapping the band B, the rond of the hydraulic cylinder C is shortened, and the tip of the band B is sent to the strapping head e by the dispenser K.
The strap chute i is retracted by the fluid pressure cylinder h, leaving the lower part of the through-hole a open.

The coil C is placed on a coil car or skid l and moves in a direction perpendicular to the paper plane of FIG. 1, reaching the through-hole a of the frame b.

Therefore, the fluid pressure cylinder h is activated to move the strap shinito i forward, and the front and rear parts of the strap chute g are moved forward.
and send out band B using dispenser K and strapping head e.

Then, the tip of band B is strap chute gwl
vf and reaches the strapping head e.

Once band B has wrapped around the strap chute gy l, f, fix the tip of band B with strapping head e, and attach it to the dispenser.
The feeding mechanism is reversed, and the rod of the hydraulic cylinder C is extended to bring the strapping head e into contact with the outer periphery of the coil C.

By reversing the feeding mechanism of the strapping head e to the dispenser, the band B is pushed up and the lid j of the strap chute g*1tf is opened by the pressing force of the band tension, and is wound around the coil C.

Once the band B is wrapped around the coil C, the overlapping portion of the band B is tied with clips using a binding machine (not shown) installed inside the strapping head e.

However, with such conventional devices, a coil car or skid is required even while winding the band around the coil, so a large number of coil cars and skids must be prepared, resulting in high equipment costs and operation and maintenance costs. This means that the coil or skid returns to its original position after the binding is completed, resulting in a long time cycle and poor efficiency.
There were other problems.

The present invention was developed with the aim of eliminating the above-mentioned drawbacks of the conventional device, and includes a coil mounting section provided at the bottom of a horseshoe-shaped frame that can be raised and lowered and is open at the bottom, and the coil is surrounded by the frame. A strapping chute is provided with a fixed strapping chute, a slidable strapping chute that can be connected to the front and rear of the fixed strapping chute, and a strapping head having a mechanism for feeding the band to the frame is provided in a manner that the strapping head is swingable. It is characterized by this.

Embodiments of the present invention will be described below with reference to the drawings.

A vertical fluid pressure cylinder 2 is installed on a required mount 1, and a horseshoe-shaped frame 4 with a through hollow part 3 and an open bottom is suspended from the lower end of the rod of the fluid pressure cylinder 2. An arm 6 that can be swung by a hydraulic cylinder 5 is pivotally attached to the frame 4, and a conventionally known strapping head 7 is attached to the tip of the arm 6 integrally with the frame 4.
A strap chute 8 for guiding and supplying the band to the strapping head 7 is disposed near the arm 6, and the strap chute 8 is fixed to the frame 4.

In addition, a strap chute 9 divided into a plurality of parts is fixed to a predetermined position of the frame 4 so as to surround the penetrating hollow part 3 as in the conventional case, and a fluid pressure cylinder 10 attached to the lower part of the frame 4 is attached to the lower part of the frame 4. A strap chute 11 is provided which moves forward and backward and is connected to the front and rear strap chutes 9 to guide the band when in use.

Thus, an endless band guide section is formed by the strapping head 7 and the strap chute 9, 11.9.8.

The connecting portion between the strap chute 8 and the strapping head 7 is as shown in FIG. 4, and the connecting portion between the strapping head 7 and the strap chute 9 is as shown in FIG. 5.

Strap shoot 8. 9. Reference numeral 11 has exactly the same structure as that of the conventional example shown in FIG.

In addition, 12 in the figure is a coil mounting part provided at the lower end of the frame 4,
13 is a deflector roll for the band; 14 is a dispenser similar to the conventional example equipped with a mechanism for sending the band to the strapping head 7; 15 is a coil car or skid on which the coil C is placed; and 16 is the band.

Next, the operation of the present invention will be explained.

When wrapping the band 16, the rod of the hydraulic cylinder 5 is extended to bring the strapping head 7 into a substantially upright position as shown in FIG. 3, so that the band 16 can be inserted from the strapping head 7 to the strap chute 9. At the same time, the band 16 is made to be able to be inserted from the strap chute 8 to the strapping head 7, and the tip of the band 16 is sent to the strapping head 7 by the dispenser 14 as shown in A in FIG. Retract the strap chute 11,
