In order to realize vacuum suction of the product a to be taken and avoid the product a to be taken from being damaged by pressure, refer to fig. 1 and 2, which relate to a material taking system.
This embodiment feeding system includes control unit 1, vacuum generator 2, material taking head 3, pressure sensor 4, elevating system 7, negative pressure detection device 5 and three-way valve 6.
The vacuum generator 2 is used for generating a novel, efficient, clean, economical and small vacuum component of negative pressure by utilizing a positive pressure air source, and can convert the positive pressure of compressed dry air into negative pressure output. The vacuum generator 2 may be a vacuum solenoid valve.
The negative pressure of vacuum generator 2 output connects the first port of three-way valve 6, and stub bar 3 is got in the second port intercommunication of three-way valve 6, and the third port intercommunication negative pressure detection device 5 of three-way valve 6, and like this, the negative pressure value that negative pressure detection device 5 detected is the negative pressure value of getting stub bar 3 absorption and waiting to get product A promptly.
In this application, the negative pressure detecting device 5 may be a negative pressure gauge, and a negative pressure limit value P1, including a negative pressure upper limit value and a negative pressure lower limit value, may be set thereon, and generally, only the negative pressure lower limit value needs to be set, because if the negative pressure value of the negative pressure lower limit value can absorb the product a to be taken, the negative pressure value greater than the negative pressure lower limit value can certainly absorb the product a to be taken.
The negative pressure detection device 5 is connected with the control unit 1, and the control unit 1 can receive the negative pressure value detected by the negative pressure detection device 5 as a basis for judging whether the product A to be taken can be sucked.
When the negative pressure value detected by the negative pressure detection means 5 is smaller than the negative pressure limit value, the control unit 1 determines that the product a to be taken is not sucked, and when the negative pressure value detected by the negative pressure detection means 5 is equal to or larger than the negative pressure limit value, the control unit 1 determines that the product a to be taken is sucked.
If the negative pressure limit value on the negative pressure detection device 5 is modified, the negative pressure limit value is output to the control unit 1, and the control unit 1 controls the vacuum generator 2 according to the negative pressure limit value, so that the negative pressure value output by the vacuum generator 2 changes along with the negative pressure limit value, the negative pressure closed-loop control is realized, the negative pressure value is ensured to be stable, and the product suction consistency is ensured.

After a product A to be taken is placed at a feeding position, the mechanical arm drives the material taking head 3 to move downwards and contact with the product A to be taken, the pressure sensor 4 detects real-time pressure of the material taking head 3 contacting with the product A to be taken and sends the real-time pressure to the control unit 1, the control unit 1 compares the real-time pressure fed back by the pressure sensor 4 with a set pressure value P2, when the real-time pressure reaches the set pressure P2, the control unit 1 controls the mechanical arm to continue to move downwards, namely the material taking head 3 is stopped from continuing to move downwards, and the product is prevented from being damaged by excessive pressure.
In this application, in order to realize reliable product absorption, control unit 1 can set for the repeated absorption and treat and get the number of times N that absorbs of product A, and the arm drives to get stub bar 3 and moves downwards and absorbs the number of times that treats and get product A promptly.
If the suction fails (namely the negative pressure value fed back to the control unit 1 by the negative pressure detection device 5 is smaller than the negative pressure limit value), the mechanical arm of the robot repeatedly performs downward movement to the material taking position to take materials, in the movement process, the control unit 1 monitors the pressure of the material taking head 3 and the product in real time, stops downward movement when the set pressure value P2 is reached, and starts to control the vacuum generator 2 to work to generate negative pressure to the material taking head 3.
After repeating N times, if the material suction still fails, the alarm mechanism 9 is used for alarming. In the present application, the alarm means 9 may be a buzzer, (blinking) indicator light or the like connected to the control unit 1.
