TECHNICAL FIELD

[0002] Copper metal is an indispensable material for cable manufacturing. In order to facilitate storage and transportation, copper metal is generally first made into a plate material with a thickness of 10-30 mm, a length and a width of about 1000 mm, and then the plate material is stacked and packaged. The so-called stacking is to stack multiple layers of copper plate material, and the so-called packaging is to bundle the stacked plate material with strapping. Generally, the strapping material required for packaging is a thin steel strip with a thickness of 1 mm and a width of 30 mm.

[0003] When the copper plate stack is transported to the cable production workshop for melting and drawing, it needs to be unbundled (cutting the steel strapping) and weighed in advance. According to the conventional method, the copper plate stack is generally unbundled by manually cutting the steel strapping with a cutting tool. This method has the disadvantages of being unprofessional, high labor intensity, and certain safety hazards. During the operation of cutting the steel strapping, the worker may be scratched by the sharp end of the cut strapping if he is not careful.

DETAILED DESCRIPTION

[0032] The application will be further described below in connection with the drawings and specific embodiments so that those skilled in the art can better understand and implement the application, but the embodiments are not intended to limit the application.

[0033] Referring to Figures 1-8 As shown in the drawings, the application discloses a material strapping cutting and weighing mechanism, which comprises a conveying line device 10, a robot cutting device, a strapping 15 pressing device, a strapping transfer device and a material weighing device.

[0034] The conveying line device 10 can sequentially transfer the packed material 14 to the strapping 15 removal station 12 and the weighing station 13. The conveying line device 10 can be composed of parallel transmission belts.

[0035] The robot cutting device is located at the strapping 15 removal station 12, and the robot cutting device can cut the strapping 15 of the packed material 14. The robot cutting device is a prior art, which moves the cutting mechanism to the target position by a multi-axis robot hand and cuts the target position, and will not be described in detail here.

[0036] The strapping 15 pressing device is located at the strapping 15 removal station 12, and the strapping 15 pressing device comprises a first magnetic adsorption assembly 82 and a first support 80 which can move up and down respectively. A plurality of first jacks are arranged on the first support 80 for jacking up the packed material 14 on the conveying line device 10. A clearance slot is formed through the first support 80, and the first magnetic adsorption assembly 82 is located within the vertical downward projection of the clearance slot to adsorb the cut strapping 15. The first support 80 can move upward to jack up the packed material 14 on the conveying line device 10. After jacking up, the bottom of the copper plate stack is about 30-50 mm higher than the top of the conveying line device 10, so as to avoid the steel strapping 15 at the bottom of the copper plate stack being squeezed between the copper plate stack and the conveying line and unable to be pulled out. The first magnetic adsorption assembly 82 pulls the cut strapping 15 (the broken strapping at the bottom of the material) downward to avoid the broken strapping 15 of the material from being stuck in the conveying line device 10 when the material is transferred to the next station, so that the copper plate stack cannot be smoothly transferred to the next station.

[0037] The strap moving device is used for moving the strap 15 of the strap removing station 12, and comprises a vehicle body 53, a first lifting driving source 51, a second magnetic adsorption assembly and a push plate 63 on the vehicle body 53. The first lifting driving source 51 drives the second magnetic adsorption assembly 54 to lift for adsorbing the strap 15 of the strap removing station 12. The vehicle body 53 can be moved from the strap removing station 12 to a strap collecting station. The push plate 63 can move downward to push the strap 15 on the second magnetic adsorption assembly 54 to fall to the strap collecting station. The strap moving device comprises a horizontal moving driving assembly 52, which comprises a frame body 50 and a horizontal moving driving source. The horizontal moving driving source drives the vehicle body 53 to move horizontally along the frame body 50. Further, the moving direction of the vehicle body 53 is perpendicular to the transmission direction of the conveying line device 10, so that the layout is more reasonable.

[0038] The material weighing device is located on the weighing station 13, and can lift and weigh the material 14 on the conveying line device 10.

[0039] The working principle of the present application is that: in the present application, the packaged material 14 is sequentially transmitted backward through the conveying line device 10, the strap 15 is cut and removed at the strap removing station 12, and the material 14 without the strap 15 is weighed at the weighing station 13, so that the degree of automation is high and the labor is saved.

[0040] Specifically, the first support 80 is lifted upward to lift the material 14 with the cut strap 15 on the conveying line device 10, so that the material 14 with the cut strap 15 is separated from the conveying line device 10. The strap moving device moves to the upper side of the material 14 to press the material 14, and the robot cutting device cuts the strap 15.

[0041] After that, the tie band 15 tightening device cooperates with the tie band transfer device to transfer the cut tie band 15 to the tie band collection station, including: (a) the second magnetic adsorption assembly 54 of the tie band transfer device adsorbs the cut tie band 15 on the top of the material 14, the vehicle body 53 drives the second magnetic adsorption assembly 54 and the cut tie band 15 thereon to move to the tie band collection station, and the push plate 63 moves downward to push the cut tie band 15 on the second magnetic adsorption assembly 54 to fall to the tie band collection station; (b) the first magnetic adsorption assembly 82 generates a magnetic adsorption force and adsorbs the cut tie band 15 on the bottom of the material 14, the first magnetic adsorption assembly 82 descends to separate the cut tie band 15 on the bottom of the material 14 from the material 14, and the conveying line device 10 continues to convey the material 14 backward; (c) the first magnetic adsorption assembly 82 moves upward to make the cut tie band 15 thereon higher than the conveying line device 10, the second magnetic adsorption assembly 54 moves to the upper side of the first magnetic adsorption assembly 82, the first magnetic adsorption assembly 82 releases the magnetic adsorption force to make the cut tie band 15 thereon transferred to the second magnetic adsorption assembly 54; (d) the vehicle body 53 drives the second magnetic adsorption assembly 54 and the cut tie band 15 thereon to move to the tie band collection station, and the push plate 63 moves downward to push the cut tie band 15 on the second magnetic adsorption assembly 54 to fall to the tie band collection station.

[0042] After that, the conveying line device 10 moves the material 14 to the weighing station 13, and the material weighing device weighs the material 14 from which the tie band 15 is removed.

[0043] Referring to Figure 2 and Figure 3As shown, further, the conveying line device 10 is also provided with a position adjustment station 11, which is located before the ribbon 15 removal station 12, and the position adjustment station 11 is provided with a centering device 30.

In the present embodiment, the second lifting driving source is used to realize the lifting of the whole roller assembly 33, and the roller assembly 33 is arranged at the conveying line device 10. When the roller assembly 33 moves upward, the packed material 14 on the conveying line device 10 is lifted by the roller assembly 33. In this way, the separation of the packed material 14 from the conveying line device 10 is realized. Then, the first side pushing assembly 31 and the second side pushing assembly 32 are used to adjust the position of the packed material 14, so that the position of the packed material 14 is centered.

At this station, the conveying line device 10 can include two parallel first conveying belts, and the roller assembly 33 is located between the two parallel first conveying belts. When the roller assembly 33 is lifted, the packed material 14 on the two parallel first conveying belts is reloaded to the roller assembly 33.
