Description

Bottle cap trademark and color difference detection device

Technical Field

The utility model relates to a bottle lid surface detection device, concrete bottle lid trade mark and colour difference detection device.

Background

When the aluminum-plastic bottle cap is detected, the front side and the side surface of the aluminum cap are detected, and whether the shape and the color difference of a trademark injected and molded on the plastic cap meet the requirements or not is also detected. When the original bottle cap detector detects trademarks and color differences, the detection cameras are arranged above the bottle cap, and the bottle cap is observed from top to bottom, so that the bottle cap needs to adopt a turnover structure, namely after the bottle cap is subjected to image pickup detection on the front side and the side surface of the aluminum cap, the bottle cap needs to be turned over by a turnover mechanism, the aluminum cap is turned upwards to be turned into a downward plastic cap, and the plastic cap is convenient to perform image pickup detection on the plastic cap. The turnover mechanism has a large volume, and in the turnover process, the aluminum cover is difficult to avoid generating aluminum scraps due to friction with the turnover mechanism, so that the assembly quality is influenced.

Disclosure of Invention

The utility model provides a bottle lid trade mark and colour difference detection device need not overturn the bottle lid, accomplishes the detection promptly in bottle lid transportation process, can realize the detection to the pattern (trade mark) and the colour difference of bottle lid upper surface or lower surface.

The technical scheme for realizing the aim of the invention is that the bottle cap trademark and color difference detection device comprises a fixed supporting plate and a rotary fluted disc arranged on the fixed supporting plate, wherein the rotary fluted disc is driven by a power shaft of a driving device to rotate, and an encoder is arranged above the middle part of the rotary fluted disc through a fixed frame;

the edge of the fixed supporting plate is provided with an optical fiber trigger;

a fixed supporting plate between the edge of the fixed supporting plate and the rotating fluted disc is provided with a fixed hole, glass is arranged on the fixed hole, and a camera is arranged below the glass;

the camera, the optical fiber trigger and the encoder are respectively connected with the controller.

The bottle cap trademark and color difference detection device also comprises a waste cap removing mechanism, the waste cap removing mechanism comprises an air blow pipe and an electromagnetic valve arranged on the air blow pipe, and the electromagnetic valve is connected with a controller;

preferably, the air blowing pipe blows air from the center of the rotating fluted disc to the edge.

Preferably, a light source is arranged between the lower part of the toughened glass and the camera.

The utility model has the advantages that, 1, trade mark and colour difference detection part are small, set up on the rotatory fluted disc of the original feeding of detection machine, do not increase the machine volume.

2. The turnover is not needed, so that the condition that aluminum scraps are generated due to the friction between the aluminum cover and the mechanism during turnover is avoided; the bottle cap can be smoothly circulated without the phenomena of cap blockage, cap clamping and the like.

3. The bottle cap is positioned by the fluted disc, and triggering is accurate.

4. The encoder is adopted for angle delay, and the method is more stable than a linear motion delay mode on a belt.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic diagram of the preferred structure of the present invention.

As shown in the figure, the device comprises a fixed supporting plate 1, a rotary fluted disc 2, an encoder 3, a fixed frame 4, an optical fiber trigger 5, glass 6, a camera 7, an air blowing pipe 8, an electromagnetic valve 9, a waste cover outlet 10 and a light source 11.

Detailed Description

As shown in fig. 1, a bottle cap trademark and color difference detection device includes a fixed supporting plate and a rotating fluted disc 2 (preferably, the fixed supporting plate 1 and the rotating fluted disc 2 are both circular and concentric circles), which is disposed on the fixed supporting plate 1, the rotating fluted disc 2 is driven by a power shaft of a driving device to rotate, and an encoder 3 (the encoder 3 can record the rotating angle of the rotating fluted disc 2 in real time) is disposed above and in the middle of the rotating fluted disc 2 through a fixed frame 4;

an optical fiber trigger 5 is arranged at the edge of the fixed supporting plate 1 (the optical fiber trigger sends out a detection signal no matter whether a bottle cap exists in the tooth hole or not);

a fixed hole is formed in the fixed supporting plate between the edge of the fixed supporting plate 1 and the rotating fluted disc 2, glass 6 (preferably toughened glass) is arranged on the fixed hole, and a camera 7 (preferably a color camera 7) is arranged below the glass 6;

preferably, a light source 11 is arranged between the lower part of the glass 6 and the camera 7, the light source 11 is an annular light source, when the light source 11 is on, light rays of the light source pass through the glass 6 and irradiate on a bottle cap to be detected, and the detection result can be more accurate.

Camera 7, optical fiber trigger 5 and encoder 3 be connected with the controller respectively, in operation, optical fiber trigger 5 gathers 2 rotation signal of rotatory fluted disc, and with signal transmission to the controller, and send actuating signal to camera 7 through the controller, camera 7 starts to shoot the bottle lid through 6 surfaces of glass after the start, and carry the picture of shooting to the controller and carry out analysis processes, the angle of the lid bottle that the numbering device will detect simultaneously is carried to the controller, if the result that the picture detected is unqualified, and the controller outwards exports the angle that the lid bottle corresponds, operating personnel can find out the bottle lid that detects not the contract according to the angle signal of carrying out, can adopt above-mentioned structure under the condition of low speed.

In the case of high speed detection, another configuration is required, as shown in figure 2,

the bottle cap trademark and color difference detection device also comprises a waste cap removing mechanism, the waste cap removing mechanism comprises an air blow pipe 8 and an electromagnetic valve 9 arranged on the air blow pipe 8, and the electromagnetic valve 10 is connected with a controller; the air blowing pipe 8 blows air from the center of the rotary fluted disc 2 to the edge, a waste cap outlet 10 is arranged on the fixed supporting plate 1 corresponding to the air blowing pipe 8, when unqualified bottle caps are found in the detection process, the angle value of the unqualified bottle caps is converted into a starting signal by the controller, when the unqualified bottle caps are transferred to the waste cap outlet 10, the controller starts an electromagnetic valve signal, the air blowing pipe blows air, and the unqualified bottle caps are blown to the waste cap outlet 10.

Principle of operation

Rotatory fluted disc tooth hole evenly distributed, when a certain tooth hole process camera axis, no matter there is the bottle lid in the tooth hole, optical fiber trigger all sends detected signal, and the camera shoots it, notes the angle value of encoder this moment simultaneously. And determining whether the trademark and the color difference of the bottle cap in the tooth hole are qualified or not through calculation, comparison and judgment of the controller, and if one is unqualified, starting the electromagnetic valve when the bottle cap passes through the waste cap outlet 10 (namely the rotary fluted disc rotates to a fixed angle value), blowing the bottle cap from the tooth hole to the waste cap outlet through the compressed air blowing pipe, and completely removing the waste cap. When no bottle cap is in the tooth hole, the controller judges the tooth hole as a waste cap to complete one air blowing action.

The utility model discloses an equipment of set on the basis of current rotatory delivery dish has realized the detection of the image and the colour difference in bottle lid arrangement and the transportation process.
