The present invention relates to a tie band cutting device, and more particularly, to a cutting device capable of cutting an injection runner (Runner) connecting each tie band in an injection molded state.

Tie bands are plastic bands used to bind or organize various objects, especially wires, wires, and ropes, in industrial and home environments.

This tieband 1 is as shown in FIG. 4;

It has a square body (3) having an inlet (2) and an outlet through which the upper and lower sides penetrate, and on one side of the body (3) is formed by forming a fastener 4 of long length in a band shape.

The inner surface of the body 3 and the one side of the fastener 4 is formed with a tooth protrusion (5) to be engaged with each other, when the insertion hole (4) is inserted into the body 3 is tightened by the combination of the tooth protrusion (5) It is a configuration that makes it impossible to relax.

The tie band 1 as described above is as shown in FIG.

Since the injection molding is made of a plastic material, a plurality of tie bands 1 are formed in a tree shape on both sides of the injection runner 6 having two to three rows in the center.

Conventionally, since the cutting of the injection runner connecting the injection-molded tie band is cut by the worker having a lifetime, the efficiency of the work is lowered and a defect occurs in the cutting process. There was a problem that a lot of discharge.

In particular, there is a problem that the physical cost of the worker is caused by the cutting tools, etc., because of the manual work, as well as the production cost is increased by the unnecessary input of manpower.

Accordingly, the present invention has been invented to solve the above problems and provides a cutting device that can mechanically cut the injection runner connecting the tie band in the state of injection molding is completed to improve productivity and reduce manpower and cost The goal is to make a contribution.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the preferred embodiment of the present invention for achieving the above object.

1 is a perspective view showing a tie band cutting device to which the technique of the present invention is applied, FIG. 2 is a perspective view showing a portion A of the tie band cutting device applied to FIG. 1, and FIG. 3 is a tie shown in FIG. It demonstrates together as a cross-sectional block diagram taken along the B-B line of a band cutting device.

In the present invention, by providing a cutting device 30 that can mechanically cut the injection runner connecting the injection molded tie band to increase the efficiency of the cutting operation and to reduce the physical fatigue of the operator is characterized in that .

The tie band cutting device 30 is;

Clamp 32 to hold the tie band that is injected and supplied on the frame 31 provided with a plurality of aluminum profiles to maintain the skeleton, and a vertical transfer portion 33 to raise and lower the clamp 32 And an injection runner connected to the horizontal transfer part 34 for moving the vertical transfer part 33 in the front and rear directions of the frame 31 and the tie band conveyed by the horizontal transfer part 34. It consists of the cutter 35.

The clamp 32 is provided with a tong type by link and lever operation by oil and pneumatic pressure, and has a type for clamping an object by opening and closing a pair of fingers 37 having a clamping groove 36. Fixing the pair at the bottom of (33) to clamp both sides of the injection runner.

The vertical transfer part 33 fixing the clamp 32 has fixing holes 42 at both sides so as to fix an intermediate portion of the guide body 41 having the guides 40 at both sides thereof with the horizontal transfer part 34. It is connected to the bridge 43 having.

A fixing plate 44 for fixing the clamp 32 is provided at an end portion of the guide 40 protruding downward from the guide body 41, and the fixing plate 44 is lifted and lowered at the center of the bridge 43. The rod 45 is also connected to the stationary plate 44 to constitute a cylinder 45.

The horizontal transfer part 34 is provided with a guide bar 52 in the longitudinal direction on the bracket 51 protruding forward from both sides of the vertical frame 50 upright to the rear of the frame 31, the guide bar ( 52 is coupled to the sliding block 53.

The sliding block 53 is connected to a rotational movement means such as an electric motor or a hydraulic motor, or is connected to a reciprocating movement means such as a hydraulic or pneumatic cylinder to reciprocate the guide bar 52, the sliding block The vertical transfer part 33 is fixed to 53.

The cutter 35 is a cutting blade 63 installed in the space 62 between the cutting body 61 and the cutting body 61 is installed to maintain a predetermined interval in the horizontal frame 60 of the frame 31. It consists of.

It will be apparent that the cutting blade 63 may be provided by various means such as fixing a blade in an upright state or installing a blade rotating by a motor.

The present invention as described above;

The tie band is installed in connection with the injection molding apparatus, and is installed at the rear end of the conveyor for discharging the injected tie band.

That is, the tie band is transferred through the conveyor and positioned below the clamp 32. At this time, the cylinder 45 of the vertical transfer part 33 operates to lower the fixing plate 44, thereby clamping the tie band 32. Descending direction.

Of course, when the clamp 32 is lowered, the finger 37 provided in the clamp 32 is lowered in an open state so as to clamp the injection runner connecting the tie bands so that the injection runner is inserted into the clamping groove 36. The pinker 37 closes upon incorporation.

As described above, when the clamp 32 clamps the injection runner, the cylinder 45 of the vertical transfer part 33 operates in reverse to raise the clamp 32 so that the injection runner is the same as the cutting blade 63 of the cutter 35. Be in position.

Then, the cutter 35 is operated and at the same time the horizontal transfer part 34 is also operated to move the vertical transfer part 33 and the clamp 32 in the cutter 35 direction, so that the injection runner on the clamp 32 moves the cutting blade. By passing through 63, the injection runner and the tie band are separated.

After the separation, the horizontal transfer unit 34 returns and the cutter 35 continues to operate for the next operation. The vertical transfer unit 33 is lowered and the injection runner clamping and the clamp 32 are operated. You can cut the injection runner connecting the tie band by repeating.

The present invention can mechanically perform the cutting operation of the tie band and the injection runner if only one operator is required to operate the cutting device 30 to increase the efficiency of the cutting operation, as well as to work in a safe state. do.

The present invention as described above has the effect of being able to contribute to the improvement of productivity and manpower and cost reduction by mechanically cutting the injection runner connecting the tie band in the state of injection molding is completed.
