The present invention does not describe apply to existing technologies.

Embodiment 1 of a cable tie tightness detection device for a fully automatic packaging and binding machine of the present invention (see Figures 1-3):

A full-automatic packing and binding machine cable tie tightness detection device, which is installed on a fully automatic packing and binding machine, is characterized in that it includes a swing rod 4, a swing rod connector 5, a swing rod position adjustment part 6, a swing rod support bracket 7, Tension spring 8, sensor mounting bracket 9, sensor 10;

The swing rod support bracket 7 is a plate-shaped component fixed and installed horizontally relative to the bow frame (the swing rod support bracket 7 is installed on the bow frame), and the swing rod position adjustment part 6 is installed at the end of the swing rod support bracket 7 in the plumb direction The screw rod of the swing rod, the swing rod connector 5 is a hinge-shaped hinge part installed on the lower end of the swing rod position adjustment part 6 by using a nut, the swing rod 4 is a plate-shaped part bent in sections, and a section of the end of the swing rod 4 is straight Yes, when the swing rod 4 is pulled tightly by the cable tie to the surface of the bundled goods, the straight section at the end of the swing rod is in the horizontal direction and fits on the surface of the goods, and the end of the swing rod 4 faces the bundled goods on the automatic packing and strapping machine In the direction of movement, one end of the swing rod is hung and installed on the swing rod connector 5, and can rotate around the hinge of the swing rod connector 5. The top end of the tension spring 8 is installed on the swing rod support bracket, and the lower end is installed on the swing rod. The tension spring 8 lifts the horizontal plate section at the end of the swing rod to a height higher than the top of the cargo when the swing rod is in a free state, and the initial height position of the swing rod in a free state can be adjusted by adjusting the nut on the swing rod position adjustment part 6 , the sensor mounting bracket 9 is a plate-shaped part installed on the swing rod support bracket 7, the position of the sensor mounting bracket 9 and the bow frame is relatively fixed, and the sensor 10 is an inductive sensor installed at the end of the sensor mounting bracket (the swing rod adopts a metal material , if the swing rod is made of glass fiber composite material or plastic material, the sensor 10 can adopt a capacitive or photoelectric sensor), and the detection end of the sensor 10 can detect that the swing rod swings away from the distance from the proximity sensor when the swing rod swings. state change.

By means of the above mechanisms and components, combined with illustrations, the working principle of a cable tie tightness detection device for a fully automatic packing and binding machine of the present invention is further explained:

When the bundled goods pass through the bow frame area, the swing bar 4 is at a height higher than the upper surface of the goods. After the tie is tied to the goods, the swing bar 4 is pulled tightly by the tie to the upper surface of the goods. If the tie If the heat sealing fails to stick the cable tie, the tension spring 8 overcomes the resistance between the cable tie and the goods to stretch and lift the swing bar. The controller detects that the swing bar is raised through the output of the sensor 10, which means that the binding is not successful. , re-bundling, after the bundling is completed, the goods leave the bow frame position, and the pendulum returns to the original height position after being pulled out from under the tie. When the height of the bundled goods changes, the initial height position of the swing rod is adjusted by adjusting the nut on the swing rod position adjustment part 6 .

Embodiment 2 (see Fig. 4) of a kind of fully automatic packing and binding machine cable tie fastening detection device of the present invention:

The difference between embodiment 2 and embodiment 1 is that the cable tie is pressed under the goods when it is bundled. Therefore, sometimes even if the cable tie is not heat-sealed, it is not easy to pull out from under the goods. In order to remove the cable tie from under the goods To pull out, it is necessary to increase the elastic force of the tension spring 8, and increasing the elastic force of the tension spring 8 will have an additional tension for the bonded cable tie, and it is easy to loosen the cable tie. In order to avoid the adverse effects of this situation, At the same time, to reduce the influence of the weight of the swing rod on the detection, the cable tie detection device is installed on the side of the bow frame of the cable tie machine (in the embodiment 1, it is installed on the top surface of the bow frame of the cable tie machine), so that the swing rod swings in the horizontal plane, and the spring The force acting on the swing rod is directed from the center of the cargo to the outside of the bow frame, so that even if the cargo is pressed against the cable tie, if the bond is not good, the cable tie can be easily pulled out, making the swing rod easier to swing.

Replace the tension spring with a torsion spring 81, and install the torsion spring 81 on the hinge shaft of the swing link connector 5.

The position adjustment part of the swing rod adopts the rotation adjustment mechanism composed of two connecting rods 61 and locking bolts to adjust the initial position of the swing rod 4, one rod 61 is installed on the bow frame 3, and the other rod is fixed on the swing rod connector 5 At the same time, it is not ruled out that the initial position of the swing rod 4 can be adjusted by means of crank sliders, guide rail sliders, etc. The adjusting part is used to adjust the distance between the swing rod and the surface of the bundled goods, so that when the end of the swing rod is attached to the surface of the goods, the end of the swing rod is parallel to the surface of the goods.

With the above mechanisms and components, the working principle of Embodiment 2 of the present invention is further described: when the bundled goods pass through the bow frame area, the swing bar 4 is in a position away from the side of the goods, and after the strap is tied to the goods, the swing bar 4 is pulled The cable tie is pulled in the horizontal plane and rotates close to the upper surface of the goods. If the heat sealing of the cable tie fails to stick the cable tie, the torsion spring overcomes the resistance between the cable tie and the goods and stretches the pendulum to its initial position. If the encoder detects that the swing rod is pulled out through the output of the encoder, it will be considered that the bundling is not successful, and the bundling will be carried out again. After the bundling is completed, the goods will leave the position of the bow frame, and the swing rod will return to the original position after being pulled out from under the tie. When the width of the bundled goods changes, the initial height position of the swing rod is adjusted by adjusting the angle between the two rods of the swing rod position adjustment part.

In addition to the above embodiments, the swing rod can also be fixedly connected to the hinge shaft of the swing rod connector, and the sensor can be replaced with an encoder. The hinge shaft of the component is fixedly connected, and the rotation range and state of the pendulum are output through the encoder.

It does not rule out that the cable tie tightness detection device of the automatic packaging and binding machine is installed on other devices that are relatively fixed in position with the automatic packaging and binding machine.

The invention is not limited to the embodiments discussed above, but other variants can be deduced from the invention by a person skilled in the art, which also belong to the subject-matter of the invention.
