Description

Technical Field

[0001] The utility model relates to the field of cloth towel veil detection equipment, in particular to a cloth towel visual detection conveying line. Background Art

[0002] After the towels are divided into pieces and sewn together, they need to be inspected to see if their double-sided yarns are qualified before they can be packaged. Previously, this was generally done manually by flipping over both sides to inspect them, which was inefficient and required a lot of labor. More importantly, it was impossible to implement automated production line operations. Utility Model Content

[0003] In response to the problems existing in the existing technology, the utility model provides a cloth towel visual inspection conveyor line. During the transfer and transportation process, the sewn single towels are first photographically inspected on the front side, then turned over, and then photographically inspected on the back side, which is used to eliminate unqualified products in the subsequent process and connect to the automated assembly line to improve production capacity.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The visual inspection conveyor line for cloth towels includes a conveyor and a turning device installed in the middle part of the conveyor, and visual inspection devices installed at both ends. The turning device includes a telescopic push rod, a towel grabbing claw, a linear slide rail, and a towel turning rod. The telescopic push rod drives the towel grabbing claw that can move up and down. The linear slide rail is installed on the racks on both sides of the conveyor in front of the towel grabbing claw. Both ends of the towel turning rod arranged horizontally on the conveyor are fixed on the sliders of the linear slide rail, and the towel turning rod starts at the rear side of the towel grabbing claw; the visual inspection device includes a line scan camera, a lighting light source, and an encoder. The line scan camera is suspended above the conveyor with the lens facing downward, the lighting light source is located below the line scan camera close to the conveyor belt of the conveyor, the encoder is close to the conveyor belt of the conveyor, and the encoder signal is connected to the line scan camera.

[0006] A further improvement plan is to set up a towel blowing rod above the front of the towel grabbing claw, and install a blowing device on the towel blowing rod.

[0007] A further improvement plan is that the telescopic push rod is installed on a gantry horizontally arranged above the conveyor, the bottom end of the telescopic push rod is connected to the mounting plate, a guide rod is installed on the gantry on both sides of the telescopic push rod, the bottom end of the guide rod is connected to the two ends of the mounting plate, and the towel grabbing claw is installed on the bottom surface of the mounting plate.

[0008] A further improvement is that the towel grabbing claw is a needle-type mechanical claw, and the linear slide rail is a linear module.

[0009] A further improvement is that the lighting light sources are respectively arranged above and below the conveyor belt of the conveyor.

[0010] A further improvement is that a light collecting plate is provided on the side of the lighting source. Beneficial effects

[0011] The utility model is connected to the conveyor line after the sewn single towel runs. The towel moves forward on the conveyor belt and first passes under the first visual inspection device, where the camera takes photos for inspection. Then the towel moves under the turning device, where the towel gripper grabs the front end of the towel and the towel turning rod moves forward to turn the towel over. The towel is then conveyed and photographed on the back for inspection, which is used to remove unqualified products in the subsequent process. The towel can then be connected to the automated assembly line to improve production capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic structural diagram of the utility model. DETAILED DESCRIPTION

[0013] like Figure 1 As shown, the utility model includes a conveyor 1 and a turning device 2 installed in the middle part of the conveyor, and a visual inspection device 3 installed at each end. The turning device 2 includes a telescopic push rod 21, a towel grabbing claw 22, a linear slide 23, and a towel turning rod 24. A gantry 26 is horizontally arranged above the conveyor 1. The telescopic push rod 21 is installed on the gantry 26. The bottom end of the telescopic push rod 21 is connected to the mounting plate 27. A guide rod 28 is installed on the gantry on both sides of the telescopic push rod 21. The bottom end of the guide rod 28 is connected to the two ends of the mounting plate 27. The towel grabbing claw 22 is installed on the bottom surface of the mounting plate 27. The telescopic push rod 21 drives the towel grabbing claw 22 that can move up and down, and the linear slide 23 is installed on the frame on both sides of the conveyor in front of the towel grabbing clamp. The two ends of the towel turning rod 24 installed horizontally on the conveyor are fixed to the slider of the linear slide 23. The towel turning rod 24 starts at the rear side of the towel grabbing clamp 22. The visual inspection device 3 includes a line scan camera 31, a lighting source 32, and an encoder 33. A mounting bracket is installed horizontally above the conveyor 1. The line scan camera 31 is installed on the bracket and suspended above the conveyor with the lens downward. The lighting source 32 is located below the line scan camera, above and below the conveyor belt of the conveyor. A light collecting plate 34 is installed on the side of the lighting source 32. The encoder 33 is close to the conveyor belt of the conveyor. The encoder 33 signal is connected to the line scan camera 31. A towel blowing rod 25 is installed above and in front of the towel grabbing clamp 22, and a blowing device is installed on the towel blowing rod 25.

[0014] The telescopic push rod 21 can be a pneumatic push rod, an electric push rod, etc., the towel grabbing claw 22 is a needle-type mechanical claw, and the linear slide rail 23 is a linear module.

[0015] The cut towel moves to the front visual inspection device, where a line scan camera captures the front view. The towel is then transferred to the flipping device, where a telescopic push rod pushes the towel gripper downward, grabbing the front end and lifting it. The flipping rod moves forward to flip the towel over. The gripper then lowers and flattens it, and the towel blower, under the action of a blower, unfolds it and fits it snugly. Driven by the conveyor, the towel moves to the rear visual inspection device, where a reverse view is captured to check for defects in the yarn surface. This helps sort qualified and unqualified products in the subsequent process. An encoder also detects the conveyor belt speed, which in turn controls the line scan camera's image frequency.
