Technical Field

The invention relates to the field of machinery, in particular to an automatic feeding and conveying device for machining and a production line.

Background

In the machining process, a rectangular plate is often used as a raw material for feeding. Whereas the existing feeding devices are usually conveyor belts. At one end of the loading device, however, usually a human or industrial robot, a rectangular plate member is placed on the conveyor belt. If the conveyer belt rotates all the time, easily lead to each rectangular plate interval difference, easily lead to the material loading too fast and make rectangular plate pile up, or the material loading too slow leads to the processing equipment vacant. In addition, the existing conveyor belt is easy to slide off the rectangular plate when being arranged obliquely, so that improvement is needed.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 1-5, the automatic feeding and conveying device for machining comprises a support 1, wherein vertical plates 2 which are arranged oppositely are installed on two sides of the support, the vertical plates 2 are hinged to transverse plates 3, the transverse plates 3 are hinged to telescopic devices 4, and the telescopic devices 4 are hinged to the vertical plates 2; two ends of the two transverse plates 3 are respectively coupled with a driving roller 16; the transmission roller 16 is sleeved with a transmission belt 5; one of the driving rollers 16 is connected with a transmission gear 6, the transmission gear 6 is meshed with an incomplete gear 7, and the incomplete gear 7 is connected with a rotating device 8; the other driving roller 16 is connected with a ratchet wheel 9, and a pawl 10 matched with the ratchet wheel 9 is arranged on the transverse plate 3. The telescoping device 4 is a cylinder or a screw mechanism. The conveyor belt 5 is provided with a plurality of transverse strips 14.

The using method of the invention is as follows:

the length of the telescopic device 4 is adjusted, so that the transverse plate 3 is inclined to adapt to the heights of different devices, then the rotating device 8 is started, the incomplete gear 7 drives the transmission gear 6 to perform intermittent transmission, so that the material is discharged when the incomplete gear stops moving, the rectangular plate is prevented from sliding downwards through the transverse strips 14, and meanwhile the distance between the rectangular plates is kept consistent. While a ratchet wheel 9 and a pawl 10 are provided to prevent the belt from reversing when the power of the transmission gear 6 is lost.

In order to ensure that the two telescopic devices 4 run consistently when inclining, so that one surface of each telescopic device is prevented from generating large torsion, the telescopic devices 4 are cylinders, displacement sensors 11 are arranged in the two cylinders, the two cylinders are communicated with a reversing proportional valve 12, and the reversing proportional valve 12 is communicated with an air compressor 13. Thus, the displacement sensor 11 detects the moving speed of the two cylinders, and the reversing proportional valve 12 adjusts the amount of gas entering each cylinder according to the moving speed, so that the two cylinders can move basically in the same direction.

The cross-section of the cross-bar 14 is triangular.

The transverse plate 3 is formed with coupling lugs 15 which are hinged to the telescopic means 4.
