Description

Technical Field

[0001] The invention belongs to the technical field of construction steel bar processing equipment, and in particular relates to a gantry type single steel bar picking device. Background Art

[0002] At present, manufacturers of threaded steel bars for construction will produce a large amount of irregular length steel bar tailings during the steel bar production process. All irregular length steel bar tailings are packaged and transferred to a unified site for secondary sorting before normal sales, or sold at a price lower than the normal market price. If sorting is performed, a large amount of manpower and a certain amount of site investment are required. If sorting is not performed, the purchasing customers will have to bear the sorting work. At present, most sorting is done manually. The whole bundle of irregular length steel bars is unpacked, and the steel bars are taken out one by one. They are then placed on the pre-prepared fixed-length tooling for size confirmation. After confirmation, the steel bars are placed in the collection position, and the same specification is packaged when the number of collected steel bars reaches the required number. This type of manual sorting requires a large amount of manpower, high labor intensity, scattered land occupation, low sorting efficiency, and there are also many safety hazards.

DETAILED DESCRIPTION

[0020] The following is a further description of a gantry type single steel bar picking device of the present invention in conjunction with the accompanying drawings and specific embodiments:

Figure 2 yes Figure 1 The structural diagram of No. 4 in the sequence, Figure 3 yes Figure 1Another visual structural diagram of sequence number 4. In the figure, the gantry type single steel bar picking device includes a gantry frame, gantry supports 1 are arranged at both ends of the gantry frame, a gantry beam 3 is mounted on the gantry support 1, a first guide rail 10 and a first rack 11 for the gantry beam 3 to move forward and backward are arranged on the gantry support 1, a moving slide 9 is arranged at both ends of the gantry beam 3, a guide rail groove is arranged on the lower bottom surface of the moving slide 9, and the guide rail groove cooperates with the first guide rail 10, the end of the gantry beam 3 is fixed on the moving slide 9, and the moving slide 9 is also provided with a beam driving motor 8 and a gear driven by the beam driving motor and meshing with the first rack 11. An electromagnetic material suction mechanism 2 and a material supporting walking mechanism 4 are arranged on the gantry beam 3. The electromagnetic material suction mechanism 2 is fixedly arranged at the end of the gantry beam 3. An electromagnet is arranged at the lower end of the electromagnetic material suction mechanism 2. An auxiliary material grabbing hook is arranged next to the electromagnet. A vertical guide column is arranged at the upper end of the electromagnet. The guide column moves up and down on the electromagnetic material suction mechanism, driving the electromagnet to move up and down to absorb the steel bars. The gantry beam 3 is provided with a second guide rail 5 and a second rack 6 for the material supporting walking mechanism 4 to move left and right. The material supporting walking mechanism 4 includes a base plate 13. The inner end surface of the base plate 13 is provided with a guide rail groove adapted to the second guide rail 5 and a walking gear meshing with the second rack 6. The outer end surface of the base plate 13 is provided with a walking motor 12. The walking motor 12 is connected to the walking gear through a reducer. A steel bar supporting wheel 14 is also provided on the outer end surface of the base plate 13. The steel bar supporting wheel 14 is fixed to the base plate through a bracket 24. The steel bar supporting wheel 14 and the bracket 24 are hinged through a rotating arm 23. A supporting wheel cylinder 18 is also provided on the outer end surface of the base plate 13. A third rack 17 is connected to the telescopic rod of the supporting wheel cylinder 18. The third rack 17 is meshed with the third gear 15 on the hinge shaft of the rotating arm. A sensor 16 is provided at the lower end of the base plate 13. The sensor 16 is provided with limit rollers 19 on both sides. The limit rollers 19 are rotatably fixed on the bottom plate 13. The lowest point of the limit rollers 19 is lower than the lower end surface of the sensor 16 to prevent the steel bar from colliding with the sensor. The lower end of the side of the bottom plate 13 is provided with a steel bar alignment wheel 20. The axis of the steel bar alignment wheel 20 is perpendicular to the axis of the limit roller 19. The wheel body of the steel bar alignment wheel 20 is lower than the limit roller 19 to ensure that the lifted steel bar is always within the effective detection range of the sensor 16. The steel bar supporting wheel 14 is rotatably hinged on the rotating arm 23. The middle part of the wheel body of the steel bar supporting wheel 14 is concave. The diameter of the middle part of the wheel body is smaller than the diameter of the two ends of the wheel body. The steel bar moves on the steel bar supporting wheel without falling. The lower part of the gantry beam 3 is provided with a plurality of supporting hooks 7 at intervals along the length direction of the gantry beam. The supporting hooks 7 are rotatably hinged on the gantry beam 3. A fourth gear 22 is provided on the rotating hinge shaft of the supporting hook 7. The fourth gear is meshed with a fourth rack 21. The fourth rack 21 is connected to the hook cylinder. The extension and retraction of the hook cylinder drives the supporting hook 7 to lift and drop.

[0022] When the whole bundle of random-sized steel bar raw materials is vibrated on the vibrating material rack, the electromagnetic suction mechanism 2 descends, and the electromagnet on it sucks up the end of a single steel bar. After the single steel bar head is sucked up, the auxiliary material grabbing hook next to it assists in grabbing the steel bar. At this time, the working zero point of the material supporting walking mechanism 4 is at the nearest point of the electromagnetic suction mechanism 2. The supporting wheel cylinder 18 on the material supporting walking mechanism 4 pushes the third rack 17, so that the third gear 15 rotates clockwise and drives the steel bar supporting wheel 14 to lift up and support the steel bar. The lifted steel bar is blocked by the limiting wheels 19 on both sides of the sensor 16 to ensure that the steel bar does not hit the sensor 16. After the sensor 16 receives the steel bar in place signal, the travel motor 12 rotates to drive the material supporting walking mechanism 4 to move to the right along the second guide rail 6. During the movement, the steel bar will be gradually lifted up. The steel bar correcting wheel 20 limits the steel bar on the steel bar supporting wheel 14 to remain within the sensing range of the sensor 16. When the material supporting walking mechanism 4 moves through the material supporting hook 7, the hook cylinder of the material supporting hook 7 will raise the hook after receiving the signal to lift the steel bar lifted by the steel bar supporting wheel 14. When the supporting walking mechanism 4 moves to the end of the steel bar, the lifted steel bar leaves the steel bar supporting wheel 14 and is separated from the sensor 16, and the supporting walking mechanism 4 stops moving. At this stage, the length of the steel bar has been measured. Because the supporting walking mechanism 4 is driven by a motor, when it runs from the working zero point to when the steel bar is separated from the sensor 16, the length of the steel bar is automatically calculated according to the number of circles the motor rotates within this distance. At this time, the steel bar has completely separated from the supporting walking mechanism 4 and is supported in the air by the supporting hook 7. Then the beam driving motor 8 on the gantry beam 3 starts to work, driving the gantry beam 3 to move along the gantry support 1, and conveying the steel bar to the top of the conveying device at the set position. When reaching the set position, the supporting hook 7 retracts, and the electromagnetic suction mechanism 2 is also demagnetized at the same time, and the steel bar falls from the gantry frame to the conveying device, completing the picking of a single steel bar.

[0023] The picking device can absorb and separate the scattered steel bars one by one without manual assistance, which perfectly solves the technical difficulties of sorting and has a high degree of automation. At the same time, it reduces the labor cost of steel bar sorting, reduces the labor intensity of workers, improves the sorting efficiency of steel bars with irregular lengths, saves floor space, and eliminates safety hazards in production.
