Description

Technical Field

[0001] The utility model relates to the technical field of feeding, in particular to a long sheet material conveyor. Background Art

[0002] A punch press is a stamping press that uses the mold on it to stamp the material into shape. It has the characteristics of high degree of automation, high production efficiency and high reliability.

[0003] Traditional punching machines are mostly operated manually when loading materials. In order to improve work efficiency, the publication number "CN207629042U" and the name "A punching machine sheet automatic loading platform" discloses an automatic loading platform for punching machine sheets, including a punching machine and a loading device. The loading device is arranged on the lower side of the punching machine mold, and a base is also arranged on the lower side of the mold. A pressure plate is arranged on the base. The loading device includes a platform arranged on both sides of the base. The platform on one side is provided with an end plate near the two ends of the punching machine. The lower side of the end plate is connected to an active rubber roller through a first bearing seat, and a cylinder is arranged on the upper side. The telescopic rod of the cylinder is connected to a driven shaft through a second bearing seat. The driven shaft is provided with a driven rubber roller at both ends. A template is arranged on the platform on the other side. The template passes through the active rubber roller and the driven rubber roller and is also located between the mold and the pressure plate. It can slide on the platforms on both sides. The active rubber roller is connected to the servo motor in order to provide power for the active rubber roller, and the friction generated between the active rubber roller and the material provides power for the movement of the material. Although it can achieve the purpose of conveying materials, slippage is likely to occur between the active rubber roller and the material. Moreover, when conveying long sheets of material, the long sheets gradually enter the punch press from front to back and gradually leave the active rubber roller, that is, the contact area between the long sheets and the active rubber roller becomes smaller and smaller, making it more likely to slip, which can easily lead to problems with inadequate feeding and affect the normal production of the punch press.

[0027] See also Figure 6 The auxiliary pulling mechanism 2 includes a pulling frame 21, a pulling linear drive device 22 and a gripping device 23. The pulling linear drive device 22 is arranged on the pulling frame 21, and the gripping device 23 is arranged on the pulling linear drive device 22. The front end of the long sheet is gripped by the gripping device 23, and the gripping device 23, driven by the pulling linear drive device 22, pulls the gripped long sheet out of the processing equipment 3 to help unloading.

[0028] In this embodiment, the pulling linear drive device 22 and the pushing linear drive device 13 both use a motor and a screw pair to achieve the purpose of linear drive. In other embodiments, the pulling linear drive device 22 and the pushing linear drive device 13 can also be a linear motor or a cylinder.

At the same time, the vacuum pump works to adsorb the tail of the long sheet material through the suction cup 18, ensuring the stability of the sheet material during the pushing process. As the long sheet material gradually moves forward, the front end of the long sheet material will extend from the other side of the processing equipment 3. At this time, the pulling linear drive device 22 drives the clamping device 23 to move to a predetermined position in the direction of the processing equipment 3, and the clamping cylinder 235 extends to drive the movable arm 232 to move, so that the clamping block 233 clamps the head end of the sheet material. Then, the pulling linear drive device 22 and the pushing linear drive device 13 work synchronously and cooperatively, and perform a pulling and a pushing action at the same time, so as to realize the automatic feeding and pulling out of the long sheet material, and the feeding effect is good.
