1. the utility model discloses simple structure, it is convenient to implement, and is with low costs, does benefit to popularization and application.
2. The utility model discloses only just can realize the safety protection function to the robot material loading mouth skip piece with a pair of safe grating, practice thrift the cost.
3. The utility model discloses a skip material loading mouth discerns people and skip, improves production line availability factor greatly.
Drawings
Fig. 1 is a schematic view of the present invention.
Detailed Description
Referring to fig. 1, the device for protecting the parts on the skip car of the automatic line comprises a material port clamping cylinder 1, a first detection switch unit 2, a second detection switch unit 4 and a safety grating 5, wherein the first detection switch unit 2 and the second detection switch unit 4 are respectively installed on supports on two sides of the safety grating 5, and the material port clamping cylinder 1 is connected with the skip car 3;
the distance between the installation position of the first detection switch unit 2 and the safety grating 5 is less than or equal to the length of the skip 3;
the distance between the installation position of the second detection switch unit 4 and the safety grating 5 is less than or equal to the length of the skip 3;
further, the detection distance in the first detection switch unit 2 and the second detection switch unit 4 satisfies the relation: and S is less than or equal to L, wherein S is the distance between the first detection switch unit 2 and the second detection switch unit 4, and L is the length of the skip car 3.
Preferably, the first detection switch unit 2 or the second detection switch unit 4 is composed of one or more detection switches.
The utility model discloses a theory of operation and use:
further, the method comprises the following specific steps:
the method comprises the following steps: a second detection switch unit 4 is arranged outside the safety grating 5 at the upper part opening of the skip 3;
step two: the first detection switch unit 2 is arranged on the inner side of the safety grating 5 at the feeding port of the skip 3, so that when the feeding of the skip 3 passes through the safety grating 5, the feeding always acts simultaneously with the first detection switch unit 2 or the second detection switch unit 4, a person only acts when the safety grating 5 is rushed by the person, the first detection switch unit 2 and the second detection switch unit 4 do not act, and therefore whether the action of the safety grating 5 is that the person enters or the skip 3 enters is identified;
step three: aiming at the process that the robot automatic line is used for loading, when a worker pushes the skip car 3 to load, the feeding port safety grating 5, the first detection switch unit 2 and the second detection switch unit 4 act simultaneously, and the automatic line does not stop acting.
Step four: after the skip car 3 is in place, personnel quit the area of the safety grating 5, press the upper part completion button, and the material port clamping cylinder 1 clamps the skip car.
Step five: after the material port clamping cylinder 1 clamps the skip car, personnel carry out the area of the safety grating 5, and the production line stops immediately.
As shown in fig. 1, in the safety protection feeding process of the skip car of the automatic line, an operator pushes the skip car 3 to load the parts, the skip car 3 firstly touches the second detection switch unit 4, and the second detection switch unit 4 acts; the skip car 3 continues to move forward, and the safety grating 5 acts; the skip car 3 continues to move forwards, and the first detection switch unit 2 acts; the skip car 3 continues to move forwards, the second detection switch unit 4 does not act, the safety grating 5 acts, and the first detection switch unit 2 acts; when the skip car 3 is in place, the personnel quit the feeding port, and only the first detection switch unit 2 acts at the moment; personnel confirm that the material loading is accomplished, and material mouth die clamping cylinder 1 presss from both sides tightly, and robot transfer machine skip material loading is accomplished, and the production line does not have the warning. After the robot automatic line skip is loaded, an object breaks into the safety grating 5, the safety grating 5 acts, and the production line is suddenly stopped. When the automatic line feeding port has no material vehicle, the first detection switch unit 2 and the second detection switch unit 4 have no action, at the moment, an object intrudes into the safety grating 5, the safety grating 5 acts, and the production line suddenly stops. Safety protection function when realizing robot transfer machine skip material loading.
