Description

Technical Field

[0001] The utility model relates to the technical field of pipe conveying, in particular to an automatic conveying device for a pipe winding material frame. Background Art

[0002] The double-drawing process using a floating plug drawing is an important process in the production of the metal casting and rolling method. The double-drawing complete set of equipment consists of an unwinding device, a first drawing device, a compensation device, a second drawing device, and a winding device. The complete set of equipment is widely used in the metal processing field.

[0003] At the present stage, in the double-drawing process, the pipe passes through the first drawing machine to the second drawing machine. After pre-bending and winding, it enters the material receiving frame. The material receiving frame is lifted onto the roller path by a crane. It is necessary to manually operate to move the material receiving frame on the crane to a suitable position, and then the tray jacks up the material receiving frame, and then the drawing operation is carried out. Due to the manual intervention and parking during the pipe threading stage, the full-automatic drawing of the double-drawing unit cannot be realized. If the material receiving frame is not directly opposite the tray when the tray is lifted during manual operation, it may damage other supporting devices. Since the distance between the two drawing machines is relatively far, it is impossible to effectively observe whether the material frame is lifted directly opposite the tray position. After the operator operates the first drawing, he needs to walk to the second drawing panel for operation, and the manual operation requires walking back and forth between the operation panels of the two drawing machines, resulting in a relatively high labor intensity.

[0004] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is generated under this background. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an automatic conveying device for a pipe winding material frame in view of the above deficiencies and defects of the prior art to solve the above problems.

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0021] See Figures 1 to 6 A kind of automatic conveying device for a pipe coiling material frame shown in the figure, which includes a conveying roller path 100 for conveying the material frame, a tray lifting device 200 arranged on the conveying roller path 100 for lifting and lowering the material frame 1, and a material retaining frame device 300 arranged on the conveying roller path 100 for restricting the forward movement of the material frame 1.

[0022] First sensors 400 for monitoring whether the material frame 1 is in place, second sensors 500 for monitoring whether the tray lifting device 200 contacts the material frame 1, and third sensors 600 for monitoring whether the material frame 1 is completed are respectively arranged on the side parts of the conveying roller path 100. The conveying roller path 100, the tray lifting device 200, the material retaining frame device 300, the first sensors 400, the second sensors 500, and the third sensors 600 are connected to a PLC control system (not shown in the figure).

[0023] The tray lifting device 200 includes a tray 210 arranged below the conveying roller path 100 for lifting the material frame 1, a lifting hydraulic cylinder 220 arranged below the conveying roller path 100 and connected to the tray 210, and a base 230 in contact with the ground for fixing the lifting hydraulic cylinder 220. In this embodiment, a first position sensor 240 and a second position sensor 250 are further arranged on the base 230. The first position sensor 240 is used to indicate the rising state of the tray 210, while the second position sensor 250 is used to indicate the non-rising state of the tray 210. When the sensor on the lifting hydraulic cylinder 220 corresponds to the first position sensor 240, it proves that the tray 210 is in the rising state. When the sensor on the lifting hydraulic cylinder 220 corresponds to the second position sensor 250, it proves that the tray 210 is in the non-rising state.

[0024] The material blocking frame device 300 includes a nylon buffer pad 310 disposed on the conveying roller 100 and used to block the material frame 1 from moving forward, a slide plate 320 disposed on the conveying roller 100 and connected to the nylon buffer pad 310, and a telescopic cylinder 330 connected to the slide plate 320 and used to drive the nylon buffer pad 310 to move up and down. The telescopic cylinder 330 in this embodiment is also provided with a third position sensor 340 and a fourth position sensor 350, the third position sensor 340 is used to identify that the material blocking frame device 300 is at the lower limit position, and the fourth position sensor 350 is used to identify that the material blocking frame device 300 is at the upper limit position. When the second sensor 500 detects the position of the material frame 1, at this time, the PLC control system controls the telescopic cylinder 330 to move upward to drive the nylon buffer pad 310 to rise so as to contact the material frame 1 and limit the movement. The fourth position sensor 350 detects that the material blocking frame device 300 is at the upper limit position. When the work is completed, the PLC control system controls the telescopic cylinder 330 to retract. The third position sensor 340 detects that the material blocking frame device 300 is at the lower limit position.

[0025] The working principle of the utility model is as follows:

[0026] When the crane lifts the material frame 1 to the left side of the conveyor roller 100, all devices are in a standby state. After that, the operator inserts the pipe and presses the start button. The conveyor roller 100 starts to drive the material frame 1 to move to the right. The telescopic cylinder 330 of the material blocking frame device 300 pushes the slide plate 320 to drive the nylon buffer pad 310 to move upward, and the position exceeds the bottom of the material frame 1. When the material frame 1 passes the pallet lifting device 200, the conveyor roller 100 stops running. The material frame 1 has inertia and hits the nylon buffer pad 310. The first position sensor 240 of the pallet lifting device 200 detects a signal. Then the pallet lifting device 200 rises to lift the material frame 1. At this time, the telescopic cylinder 330 retracts to drive the slide plate 320 and the nylon buffer pad 310 to fall. After the pipe threading is completed, it is collected into the material frame 1, and the drawing machine draws normally. When the drawing is completed, the pallet lifting device 200 falls, and the second position sensor 250 detects the signal and transmits it to the PLC control system. The PLC control system controls the conveyor roller 100 to start running to the right until the third sensor 600 detects the material frame 1. Then the crane lifts the material frame 1 and reloads it on the left side of the conveyor roller 100 to cycle.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
