Technical Field

[0001] The utility model relates to the technical field of button detection equipment, and more specifically to a button detection and screening equipment. Background Art

[0002] As a traditional and commonly used clothing product, buttons come in a variety of styles. Traditional buttons use a punching process to punch multiple holes on the button surface for the button to be installed on clothing. The location, number and size of the holes determine whether the button can be used normally. At the same time, due to the instability of processing, buttons are prone to problems such as button incompleteness, cracks, pores and color difference.

[0003] At present, the existing button detection equipment is generally based on visual recognition to detect the hole position, quantity and size of the button. For example, the defective button rejection system based on machine vision and PLC technology disclosed in the announcement number CN109248868A basically meets the requirements for button detection and rejection, but it still has some defects: the existing equipment uses a robot to turn over, and the cost of the robot is high, and the daily maintenance is also difficult; and the use of a robot to turn over requires a high accuracy of the position of the button on the conveyor belt. Once the speed of the conveyor belt becomes faster and runs for a long time, the problem of turning over failure is prone to occur. At the same time, the robot is not fast enough in turning over, and the overall production efficiency is not high.

[0004] Based on this, the utility model proposes this application to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] This embodiment discloses a button detection and screening device, such as Figure 1-4As shown, the machine comprises a frame 1, on which an upper conveyor belt 2 and a lower conveyor belt 3 are arranged for conveying buttons, one end of the upper conveyor belt 2 and the lower conveyor belt 3 are aligned and provided with a turning area 4, the buttons are conveyed by the upper conveyor belt 2 and enter the turning area 4 for turning over, and the turned buttons enter the lower conveyor belt 3 for conveyance. By providing upper and lower conveyor belts, the side of the button facing up on the upper conveyor belt 2 is turned down from top to bottom, and the side originally facing up is turned down, so that the button can be turned over more conveniently with the turning area 4.

[0026] Furthermore, the upper conveyor belt 2 includes a first roller 201 and a second roller 202 around which the conveyor belt is wound. The second roller 202 is arranged in the turning area 4. The upper end of the second roller 202 is flush with the upper end of the first roller 201, and the lower end of the second roller 202 extends to the surface of the lower conveyor belt 3. Figure 2-3 The diameter of the second roller 202 is equivalent to the distance between the upper conveyor belt 2 and the lower conveyor belt 3. Therefore, when the conveyor belt passes around the second roller 202, it can take over the upper conveyor belt 2 and correspond to the lower conveyor belt 3 at the same time, allowing the buttons to enter the lower conveyor belt 3 from the upper conveyor belt 2.

[0027] Furthermore, a transition conveyor belt 5 is provided in the turning area 4. The transition conveyor belt 5 is arranged in an arc shape and wrapped around the outer side of the second roller 202. A gap 6 having the same thickness as the button 11 is left between the transition conveyor belt 5 and the upper conveyor belt 2. Figure 3 , through the gap 6, the button 11 is clamped and pressed, so that when the button moves in the flip area 4, the distance between each button 11 is basically consistent with that when entering, and there will be no stacking or collision of buttons. At the same time, an adjusting roller 501 is provided at the end of the transition conveyor belt 5 corresponding to the upper conveyor belt 2, and the adjusting roller 501 can be moved closer to or farther away from the second roller 202. The adjusting roller 501 can be adjusted by manual bolt adjustment, or by automatic control such as a cylinder or an electric cylinder. The role is to expand or reduce the gap 6 at the time of entry to ensure that buttons of different thicknesses can be adapted. As for the gaps at other positions between the transition conveyor belt 5 and the upper conveyor belt 2, since the belt body of the conveyor belt itself is elastic, the belt body will be pulled after the adjustment roller 501 moves, and the adaptation can be completed by relying on the elasticity of the belt body itself.

[0028] Further, see Figure 2-3 Since one end of the transition conveyor belt 5 cooperates with the upper conveyor belt 2 and the other end cooperates with the lower conveyor belt 3, as a preferred embodiment of the present invention, the lower conveyor belt 3 and the transition conveyor belt 5 can be directly integrated. This not only simplifies the structure, but also allows the button to directly enter the lower conveyor belt 3 after turning over, which is very convenient.

[0029] For further information, see Figure 2 The conveying paths of the upper conveyor belt 2 and the lower conveyor belt 3 are both provided with a detection device 7 and a rejection device 8 distributed front and back along the conveying direction. Figure 2 As shown by the arrows in the figure, the upper conveyor belt 2 conveys to the right, and the lower conveyor belt 3 conveys to the left. The detection device 7 is used to detect whether the button is a defective product, and the rejection device 8 is used to reject the defective button. Figure 4 The detection device 7 includes a camera 701, a sensor 702 and a recognition system (not shown in the figure). The sensor 702 can be a fiber optic sensor, or an infrared, ultrasonic or other sensor, as long as it can quickly detect the button. The camera 701 is connected to the recognition system, which can be a computer. The camera 701 is connected to the computer for transmitting photos. When the sensor 702 detects a button, the camera 701 takes a photo of the button, and then determines whether the button in the photo is qualified through the recognition system.

[0030] Reference Figure 2 and Figure 4 The rejecting device 8 includes a controller (not shown in the figure), an air blowing mechanism 801, a falling channel 802 and a defective product box 803. The recognition system is electrically connected to the air blowing mechanism 801 through the controller. Therefore, when the recognition system determines that the button is qualified, the air blowing mechanism 801 is stopped by the controller and the button is transported normally. When the recognition system determines that the button is unqualified, the air blowing mechanism 801 is controlled by the controller to work and the button is blown away. The air blowing mechanism 801 can use a solenoid valve and an air nozzle. The solenoid valve is connected to an external air source and blows the unqualified defective buttons into the falling channel 802 through the air nozzle. The falling channel 802 is connected to the defective product box 803, so that the defective buttons fall into the defective product box 803 for collection.

[0031] Further, see Figure 1-2 , and also includes a feeding mechanism 9 and a discharging box 10. The feeding mechanism 9 is connected to the starting end of the upper conveyor belt 2 and is used to transport the buttons into the upper conveyor belt 2; the discharging box 10 is arranged at the end of the lower conveyor belt 3 and is used to collect qualified buttons.

[0032] Further, see Figure 1 and Figure 4 In this embodiment, the detection device 7 and the rejection device 8 are both arranged in the middle of the upper conveyor belt and the lower conveyor belt. The advantage of being arranged in the middle is that the detection device 7 and the rejection device 8 can be symmetrically arranged in two groups, corresponding to the left and right sides of the conveyor belt respectively, so that two rows of buttons can be inspected at the same time, thereby improving work efficiency.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
