DETAILED DESCRIPTION

[0026] like Figures 1 to 13 As shown, an automatic unloading and packaging mechanism for pipes includes an unloading platform 1, a gantry 2, an automatic unloading mechanism 3 and a packaging mechanism 4.

[0027] Furthermore, the top of the unloading platform 1 is tilted, and this design allows the steel pipe to automatically roll toward the lower end thereon.

[0028] Furthermore, a crossbeam 21 is installed on the gantry 2, and a vertical frame 22 is installed at one end of the crossbeam 21; A side bracket 23 is installed on the gantry 2. The side bracket 23 is roughly L-shaped. A limit plate 24 is installed at one end of the side bracket 23. The limit plate 24 is arranged parallel to the top of the unloading platform 1. The setting of the limit plate 24 is used to prevent the steel pipe from tilting during the unloading process. The limiting plate 24 and the top of the unloading platform 1 are parallel to each other and there is a gap between them, and the gap is used for the passage of the steel pipe.

[0029] Furthermore, the automatic unloading mechanism 3 is provided on the unloading platform 1 and is used to unload the steel pipe onto the unloading platform 1, comprising: A fixed frame 31 on which a shaft 32 is rotatably mounted; a first motor 33 , the output shaft of which is connected to the shaft 32 ; There are at least two blanking plates 34 installed on the shaft 32. The blanking plates 34 are provided with a material trough 3401. The blanking plates 34 are provided with a material trough 3401. The material trough 3401 can be divided into two parts. The first part is a small circle with an open end, and the second part is an arc surface tangentially contacting the small circle. The first part is used to accommodate the steel pipe during the blanking process, and the second part is used for smooth transition from the first part to the blanking platform 1 during transportation, so as to avoid slow blanking or jamming. The first electric push rod 35 has a first connecting block 3501 mounted on its output shaft. A push block 3502 is mounted on the first connecting block 3501. The first electric push rod 35 drives the push block 3502 to move, thereby pushing the steel pipe to move on the unloading platform 1, thereby preventing the steel pipe from being stuck between the limit plate 24 and the unloading platform 1. One end of the shaft 32 is rotatably provided with a first bracket, which is mounted on the unloading platform 1. The other end of the shaft 32 is rotatably provided with a second bracket, which is mounted on the unloading platform 1. The first motor 33 is mounted on one end of the second bracket. The first electric push rod 35 is parallel to the ground. The first electric push rod 35 is parallel to the ground so that the push block 3502 is in two states between the unloading platform 1: State 1: When the first electric push rod 35 is in the retracted state, the relative position of the push block 3502 is close to one end of the unloading platform 1, that is, the upper position of the unloading platform 1. In this state, the push block 3502 is located below the top of the unloading platform 1; State 2: When the first electric push rod 35 is in the extended state, the relative position of the push block 3502 is at a position away from one end of the unloading platform 1, that is, the unloading platform 1 is from high to low. In this state, the push block 3502 is partially higher than the top of the unloading platform 1; When the first state transitions to the second state, the push block 3502 gradually moves from below the top of the unloading platform 1 to above the top of the unloading platform 1; Furthermore, the automatic unloading mechanism 3 further includes: A third bracket is mounted on one end of the unloading platform 1, and the first electric push rod 35 is mounted on the third bracket; The first guide rail 36 is installed at one end of the unloading platform 1. A first guide block 3601 is slidably provided on the first guide rail 36. The first guide block 3601 is installed at one end of the push block 3502. The mutual cooperation between the first guide block 3601 and the first guide rail 36 limits the movement trajectory of the push block 3502.

[0032] The driving sources of each component of this device are all controlled by programming.

[0033] An automatic pipe unloading and packaging mechanism 4, the working principle is as follows: S1; After the processing is completed, the steel pipe is dropped from the processing device to this device, and the steel pipe falls into the trough 3401 on the unloading plate 34. The shaft 32 is driven by the first motor 33 to rotate, and the shaft 32 drives the unloading plate 34 to rotate, thereby driving the trough 3401 to alternately move, driving the steel pipe to move. When the steel pipe moves from the trough 3401 to the upper side of the top of the unloading platform 1, the steel pipe rolls from the trough 3401 onto the unloading platform 1; S2; the push block 3502 is driven by an electric push rod to push the steel pipe on the unloading platform 1, so that the unloading of the steel pipe is smoother; S3; The fifth motor 57 drives the screw rod 58 to rotate, and the screw rod 58 drives the slider 59 mounted thereon to move, thereby driving the movable frame 54 to move, and the movable frame 54 drives the second electric push rod 55 and the limit plate 24 mounted thereon to move, and the steel pipe is blocked by the movement of the limit plate 56 to prevent the steel pipe from falling from the unloading platform 1 without going through the next process; S4; the first gear 4306 is driven by the second motor 4305 to move on the first rack 4301, thereby driving the horizontal plate 4304 to move, and adjusting the position of the grabbing portion 41 (along the Y-axis direction); S5; the second gear 4207 is driven to rotate by the third motor 4206, and the second gear 4207 drives the second rack 4205 to move, thereby driving the longitudinal beam 4202 to move, and the longitudinal beam 4202 drives the fixed frame 4101 to move, thereby driving the grab block 4102 to move (along the Z-axis direction); S6; the above S4-S5 are repeatedly executed multiple times according to a pre-programmed program (in the above S4-S5, when the grabbing block 4102 grabs the steel pipe, that is, when grabbing it from the unloading platform 1, the grabbing block 4102 is magnetic, and when the steel pipe is released, that is, when it is conveyed to the conveying roller after being grabbed, the grabbing block 4102 is non-magnetic. The magnetic control of the grabbing block 4102 is controlled by programming, and the magnetic control of the grabbing block 4102 can be achieved by powering it on or off), and the steel pipes are placed on the conveying roller 4404 in a regular pattern; S7; After a group of steel pipes are placed (i.e., a completed programming operation is completed), the staff bundles them, and then drives the transmission rod 4408 to rotate through the fourth motor 4407, and drives the right-angle transmission device 4409 through the transmission rod 4408, and then drives the conveyor roller 4404 to rotate, thereby transporting batches of steel pipes.
