Description

Technical Field

[0001] This invention relates to a detection device, and more particularly to a detection device for materials during transportation, such as those on roller conveyors and chains. Background Technology

[0002] During production, materials often need to be checked during transportation to ensure they reach specific locations or to measure their quantity, in order to control and manage the production process. Material transportation is often affected by adverse environmental factors such as iron filings, water, and oil, making photoelectric detection components like proximity switches unreliable and unsuitable for this purpose. Furthermore, when materials are heavy or moving at high speeds, traditional limit switches are difficult to install and adjust, impacting their lifespan. Summary of the Invention

[0003] To address the above problems, the present invention provides a detection device.

[0004] To achieve the above objectives, the detection device of the present invention includes: a fixed frame, with a through-plane formed above the fixed frame; a hinged sleeve disposed on the fixed frame below the through-plane; a contact rod disposed on one side of the hinged sleeve; a counterweight disposed downward on the other side of the hinged sleeve; a detection rod disposed below the hinged sleeve; and a stop member disposed on the fixed frame corresponding to the detection rod; wherein,

[0005] When no material passes through the plane, the contact rod tilts upward under the weight of the counterweight, and at the same time, the lower end of the detection rod abuts against the stop, causing the free end of the contact rod to rise above the predetermined height of the plane.

[0006] When the material passes through the plane, the bottom surface of the material presses down on the contact rod, and at the same time, the lower end of the detection rod moves upward in the opposite direction to the upper stop position of the detection rod;

[0007] A sensor is installed on the fixed frame at the corresponding top stop position.

[0008] Furthermore, an adjustment block is provided on the fixed frame corresponding to the lower stop point of the free end of the contact rod.

[0009] Furthermore, the fixed frame comprises a column and two parallel uprights disposed above the column; the upper edges of the two uprights form a through plane.

[0010] Furthermore, the hinged sleeve is hinged at one end between the two upright plates.

[0011] Furthermore, the stop is located on the side of the column near the hinge sleeve.

[0012] Furthermore, a sensor bracket is provided on the column relative to the upper stop point of the detection rod, and the sensor is mounted on the sensor bracket.

[0013] Further, the adjusting block is arranged between the two vertical plates by a pin.

[0014] Further, long holes are arranged on the two vertical plates corresponding to the pin of the adjusting block along the through plane direction, and an adjusting device is arranged on the rear vertical plate corresponding to the position of the adjusting block to move the adjusting block along the through plane direction.

[0015] Further, a touch rod buffer pad is arranged on the lower end of the touch rod corresponding to the position of the adjusting block.

[0016] Further, a detection rod buffer pad is arranged on the lower end of the detection rod corresponding to the position of the stopper.

[0017] The present application detects the position and quantity of the material by arranging the touch rod higher than the position of the material, and the touch rod can be automatically reset by arranging the counterweight. The detection device has simple structure, convenient adjustment, stable and reliable detection, and long service life. BRIEF DESCRIPTION OF DRAWINGS

A detection rod 23 is arranged below the hinged sleeve; a stopper (a vertical column 11 in the figure) is arranged on the fixed frame corresponding to the detection rod; wherein,

[0029] When there is no material passing through the through plane, the touch rod 22 is raised upward under the action of the gravity of the counterweight 6, and the lower end of the detection rod is abutted against the stopper, so that the free end of the touch rod exceeds the predetermined height of the through plane upward;

[0030] When the material passes through the through plane, the bottom surface of the material presses the touch rod downward, and the lower end of the detection rod moves upward to the upper stop point of the detection rod in the opposite direction;

[0031] A sensor 4 is arranged on the fixed frame corresponding to the upper stop point, which can be a photosensitive switch, a contact switch or a travel switch, etc., which can be designed according to the needs.
