Description

Technical Field

[0001] The invention relates to the field of automation equipment, and in particular to a full-automatic powder assembling machine. Background Art

[0002] Eye shadow is a cosmetic product applied on the eyelids (i.e., eyelids) and the corners of the eyes. When producing eye shadow, it is necessary to put the pressed powder into a block into an eye shadow box. In the prior art, it is generally achieved manually. Frequent repetitive labor will make workers tired and the production efficiency is low. Based on this point, after searching, a Chinese utility model patent with authorization announcement number CN221318110U was found, which discloses a double-station mold powder and eye shadow aluminum dish feeding and placing equipment. The feeding and placing equipment replaces the manual feeding and placing operations of the powder and eye shadow aluminum dishes, improves the feeding and placing efficiency of the powder and eye shadow aluminum dishes, and reduces the production cost of the powder and eye shadow aluminum dishes. However, it still has some shortcomings: it is generally The powder compacts are placed in the material box through the placing robot technology. Therefore, the material box needs to pause in front of the placing robot, and then the powder compacts are pulled one by one and placed in the material box by the placing robot. This method is suitable for placing only a single type of powder compacts in the material box, but if there are multiple types of powder compacts of different colors in the material box, it is easy to think of that the corresponding powder compacts of multiple types of powder compacts of different colors are pulled into the material box one by one by the robots corresponding to the multiple types of powder compacts of different colors. Then, the material box needs to be pulled and moved to each robot in turn, paused, and waited for the powder compacts to be placed. This frequent pause method will delay production efficiency. Therefore, based on the eye shadow box with powder compacts of different colors, the present invention proposes a fully automatic powder assembling machine. Summary of the invention

[0003] In order to solve the problems mentioned in the above background, the present invention provides a fully automatic powder assembly machine.

[0004] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows.

[0005] A fully automatic powder grouping machine comprises a main conveyor belt, one side of the main conveyor belt is provided with a plurality of placing mechanisms in an array along its own conveying direction, the placing mechanisms comprise a fixed frame, a sub-conveyor belt and side conveyor belts and a synchronous belt respectively located on both sides of the sub-conveyor belt along its own conveying direction are installed on the fixed frame, and the conveying directions of the three are all arranged horizontally and perpendicular to the conveying direction of the main conveyor belt;

[0006] A connecting frame is installed on the fixed frame, and a laser sensor facing the discharge end of the conveyor belt is installed on the connecting frame. When the powder cake is pulled by the conveyor belt, when the laser sensor senses the appearance of the powder cake, the conveyor belt is paused. At this time, the position of the powder cake is named position a;

[0007] A feeding assembly is installed at the feeding end of the sub-conveyor belt, and a traction member for pulling the powder cake into the eye shadow box is installed on the connecting frame. During the process of the powder cake falling into the eye shadow box, the main conveyor belt keeps running at a constant speed.

[0008] Furthermore, a defective product box is arranged below the discharge end of the side conveyor belt, a camera located above the feed end of the sub-conveyor belt is installed on the connecting frame, and a plurality of brushes are arranged in an array along the extension direction on the outer surface of the synchronous belt.

[0009] Furthermore, a slide and a linear module 1 for driving the slide to move are installed on the fixed frame. The movement direction of the slide is horizontally arranged and perpendicular to the conveying direction of the main conveyor belt. The slide and the connecting frame form a sliding connection along the conveying direction of the main conveyor belt. A linear module 2 for driving the connecting frame to move is installed on the slide.

[0010] Further, the loading assembly includes a slideway parallel to the conveying direction of the sub-conveyor belt, the upper surface of the slideway is flush with the upper surface of the sub-conveyor belt and the output end of the slideway is close to the feed end of the sub-conveyor belt;

[0011] The loading assembly also includes a feeding conveyor belt that is higher than the branch conveyor belt and a guide pipe arranged between the discharge end of the feeding conveyor belt and the input end of the slide. The width of the guide pipe gradually narrows and the narrow end is connected to the input end of the slide.

[0012] Furthermore, two positioning plates are arranged above the feed end of the sub-conveyor belt, and the distance between the two positioning plates first decreases and then becomes constant along the conveying direction of the sub-conveyor belt, and the distance between the positioning plates and the upper surface of the sub-conveyor belt is less than the thickness of the powder cake.

[0013] Furthermore, the traction component includes a mounting frame connected to the connecting frame, on which a rotating seat with a vertically arranged axis and a motor for driving the rotating seat to rotate are mounted, and four groups of adsorption components are arranged in an array along the circumferential direction on the rotating seat.

[0014] Furthermore, the adsorption component includes a motor 2 which is arranged on a rotating seat and has an output shaft in the shape of a hollow shaft. A negative pressure tube is installed in the output shaft of the motor 2 through a spline, and when the negative pressure tube moves along the axial direction, the motor 2 and the negative pressure tube maintain a dynamic connection through the spline. A avoidance hole for avoiding the negative pressure tube is provided on the rotating seat. The upper end of the negative pressure tube is sealed, the lower end is open, and a negative pressure adsorption head is installed after passing through the avoidance hole. The outer cylindrical surface of the negative pressure tube is also provided with an air nozzle close to the upper end of the negative pressure tube. The outer cylindrical surface of the negative pressure tube is also provided with an external step located above the motor 2. The outer sleeve of the negative pressure tube is provided with a spring located between the external step and the motor shell of the motor 2. A pressure sensor is also provided in the negative pressure tube, and the pressure sensor is connected to the negative pressure adsorption head.

[0015] Furthermore, a main air pipe is installed on the rotating seat, the input end of the main air pipe is connected to the negative pressure pump through a rotating joint, the output end and the air nozzle are connected through an air distribution pipe, and a three-way valve is arranged on the air distribution pipe. There are four corresponding air distribution pipes. The three-way valve in the open state is used to realize the connection between the air distribution pipe and the negative pressure pipe, and the three-way valve in the closed state is used to realize the connection between the negative pressure pipe and the outside world.

[0016] Furthermore, when one of the four groups of adsorption components is located at position a, the positions of the remaining three groups of adsorption components are respectively position b, position c and position d. The adsorption component at position b is located above the side conveyor belt, and the adsorption component at position d is located above the synchronous belt. During operation, when the motor 2 drives the rotating seat to rotate, the adsorption component passes through position a, position b, position c and position d in sequence. When the adsorption component rotates with the rotating seat, the speed of the adsorption component is composed of a tangential component speed and a radial component speed. When the direction of the tangential component speed of the adsorption component is consistent with the conveying direction of the main conveyor belt, the position of the adsorption component is named position e, and the tangential component speed of the adsorption component at position e is equal to the conveying speed of the main conveyor belt.

[0017] Furthermore, the mounting frame is slidably installed with a lifting rod 1 and a lifting rod 2 in the vertical direction, and a linear module 3 for driving the lifting rod 1 to move and a linear module 4 for driving the lifting rod 2 to move are installed on the mounting frame. When the lifting rod moves down, the negative pressure tubes of the adsorption components at positions a, b, and d can be pressed at the same time. When the lifting rod 2 moves down, the negative pressure tube of the adsorption component at position e can be pressed.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present application, the powder cake is pulled into the eye shadow box by the placing mechanism. During this process, when the adsorption component with the powder cake adsorbed on it rotates to position e, the adsorption component releases the adsorption of the powder cake, and at this time, the position corresponding to the powder cake in the eye shadow box is also located below position e. At this time, the adsorption component at position e is driven downward by the cooperation of the linear module four and the lifting rod two, so that the powder cake has an initial vertical velocity downward and is close to the eye shadow box. Therefore, the time spent by the powder cake to fall into the eye shadow box is very short. Since the initial horizontal velocity of the powder cake is in the same direction and speed as the conveying speed of the main conveyor belt, the powder cake can be regarded as maintaining a relatively static state with the eye shadow box and falling into the eye shadow box in a very short time, so that the powder cake can be delivered into the eye shadow box uninterruptedly and efficiently.

DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0031] Reference Figure 1-Figure 8 A fully automatic powder grouping machine includes a main conveyor belt 100 and a placing mechanism 200. The placing mechanism 200 is arranged in an array along the conveying direction of the main conveyor belt 100 to form a plurality of groups of powders corresponding to different colors of powders in an eyeshadow box.

[0032] When in use, the eyeshadow boxes are placed one by one on the main conveyor belt 100 by using the existing robot technology. The advantage of using the robot technology is that the position of the eyeshadow boxes placed on the main conveyor belt 100 is more accurate. This is the performance of the robot technology and will not be described in detail.

[0033] Afterwards, the main conveyor belt 100 runs, pulling the eye shadow box to move at a constant speed. During the constant speed movement, the eye shadow box passes through multiple sets of placement mechanisms 200 in sequence. The placement mechanisms 200 will pull the powder cakes into the corresponding positions in the eye shadow box, thereby achieving the purpose of automated production. At the same time, since the main conveyor belt 100 continuously pulls the eye shadow box to move, there is no need to pause in the middle, so the production efficiency can be significantly improved.

[0034] Reference Figure 3 The placing mechanism 200 includes a connecting frame 210, and the connecting frame 210 can move in the plane coordinate system. Furthermore, the placing mechanism 200 also includes a fixed frame 206, on which a slide 208 and a linear module 207 for driving the slide 208 to move are installed. The movement direction of the slide 208 is arranged horizontally and perpendicular to the conveying direction of the main conveyor belt 100. The slide 208 and the connecting frame 210 form a sliding connection along the conveying direction of the main conveyor belt 100. A linear module 209 for driving the connecting frame 210 to move is installed on the slide 208. Through the linear module 207 and the linear module 2 The cooperation of 209 can drive the connecting frame 210 to move in the plane coordinate system composed of the movement direction of the slide 208 and the movement direction of the connecting frame 210. Its significance lies in that the traction member used to pull the powder into the eye shadow box is installed on the connecting frame 210. The positions of powders of different colors and types in the eye shadow box are different. Therefore, the traction member is adjusted by moving the connecting frame 210, so that the traction members in different placement mechanisms 200 can accurately pull the corresponding powder into the eye shadow box. Even if the design of the powder distribution in the eye shadow box is adjusted, the placement mechanism 200 can also adapt to the corresponding adjustment.

[0035] Reference Figure 4 The placement mechanism 200 also includes a sub-conveyor belt 204 installed on a fixed frame 206 and a side conveyor belt 212 and a synchronous belt 213 respectively located on both sides of the sub-conveyor belt 204 along its own conveying direction. The conveying directions of the three are all arranged horizontally and perpendicular to the conveying direction of the main conveyor belt 100.

[0036] A laser sensor 211 is installed on the connecting frame 210, which is opposite to the discharge end of the conveyor belt 204. When the powder cake is pulled by the conveyor belt 204, when the laser sensor 211 senses the appearance of the powder cake, it sends a signal to the controller to pause the conveyor belt 204. The position of the powder cake at this time is named position a, and the traction component will adsorb the powder cake at this position. The laser sensor 211 can be realized by existing technology and will not be elaborated on. The laser sensor 211 is set because the position of the traction component may need to be adjusted, and the laser sensor 211 is adjusted accordingly, so the position a will also be adaptively adjusted accordingly.

[0037] A defective box is provided below the discharge end of the side conveyor belt 212, and a camera located above the feed end of the sub-conveyor belt 204 is installed on the connecting frame 210. Its significance lies in that the quality of the powder cake can be monitored through the camera and the corresponding AOI technology, which is achievable with the existing technology. If the powder cake has defects, the traction component will pull the powder cake at position a into the side conveyor belt 212, and finally into the defective box.

[0038] The outer surface of the synchronous belt 213 is provided with a plurality of brushes 214 in an array along the extension direction. When the traction member moves to the position a, its adsorption end will pass through the brush 214 , and the adsorption end will be cleaned by the brush 214 .

[0039] Reference Figure 2-Figure 4 The placement mechanism 200 also includes a loading component for conveying powder cakes to the sub-conveyor belt 204.

[0040] The loading assembly includes a slideway 203 parallel to the conveying direction of the sub-conveyor belt 204 , the upper surface of the slideway 203 is flush with the upper surface of the sub-conveyor belt 204 and the output end of the slideway 203 is close to the feed end of the sub-conveyor belt 204 .

[0041] The loading assembly also includes a feeding conveyor belt 201 that is higher than the sub-conveyor belt 204 and a guide pipe 202 arranged between the discharge end of the feeding conveyor belt 201 and the input end of the slide 203. The width of the guide pipe 202 gradually narrows, and the narrow end is connected to the input end of the slide 203.

[0042] Two positioning plates 205 are arranged above the feed end of the sub-conveyor belt 204. The distance between the two positioning plates 205 first decreases and then becomes constant along the conveying direction of the sub-conveyor belt 204. The distance between the positioning plate 205 and the upper surface of the sub-conveyor belt 204 is less than the thickness of the powder cake, and the minimum distance between the two positioning plates 205 is consistent with the diameter of the powder cake.

[0043] By using the existing technology, the powder cake is placed on the feeding conveyor belt 201, and the powder cake is sent to the guide pipe 202 through the feeding conveyor belt 201, and the powder cake is sent to the sub-conveyor belt 204 through the guide pipe 202 and the slide 203. Then, in the process of the sub-conveyor belt 204 pulling the powder cake to move, the powder cake is straightened by the cooperation of the two positioning plates 205.

[0044] Reference Figure 5-Figure 8 The traction member includes a mounting frame 215 connected to the connecting frame 210, on which a rotating seat 219 with a vertically arranged axis and a motor 218 for driving the rotating seat 219 to rotate are mounted, and on the rotating seat 219, four groups of adsorption components are arranged in an array along the circumferential direction.

[0045] The adsorption component includes a second motor 225 which is arranged on a rotating seat 219 and has an output shaft in the shape of a hollow shaft. A negative pressure tube 227 is installed in the output shaft of the second motor 225 through a spline, and when the negative pressure tube 227 moves along the axial centerline direction, the second motor 225 and the negative pressure tube 227 maintain a power connection through the spline. In addition, a avoidance hole for avoiding the negative pressure tube 227 is provided on the rotating seat 219. The upper end of the negative pressure tube 227 is blocked, the lower end is open, and a negative pressure adsorption head 229 is installed after passing through the avoidance hole. The outer cylindrical surface of the negative pressure tube 227 is also provided with an air nozzle 228. The air nozzle 228 is close to the upper end of the negative pressure tube 227. The outer cylindrical surface of the pressure tube 227 is also provided with an external step located above the motor 225, and the outer sleeve of the negative pressure tube 227 is provided with a spring 226 located between the external step and the motor housing of the motor 225. Preferably, a pressure sensor 230 is also provided in the negative pressure tube 227, and the pressure sensor 230 is connected to the negative pressure adsorption head 229. During the downward movement of the negative pressure adsorption head 229, when it is obstructed, the pressure sensor 230 can sense it in time and send a signal to the controller to stop the negative pressure adsorption head 229 from moving downward. See the following description for details. This pressure sensor 230 technology is achievable by existing technology and will not be elaborated on.

[0046] Reference Figure 7 , an air suction component is also installed on the rotating seat 219, which is used to suck the air in the adsorption component to form a negative pressure at the negative pressure adsorption head 229 to achieve the adsorption effect. Specifically, the air suction component includes a main air pipe 222, the input end of the main air pipe 222 is connected to a negative pressure pump through a rotating joint, the output end and the air nozzle 228 are connected through a branch air pipe 223, and a three-way valve 224 is provided on the branch air pipe 223, and the branch air pipe 223 is correspondingly provided with four; when the three-way valve 224 is opened, it is used to realize the connection between the branch air pipe 223 and the negative pressure pipe 227, and a negative pressure is formed at the negative pressure adsorption head 229 through the negative pressure pump. When the three-way valve 224 is closed, it is used to realize the connection between the negative pressure pipe 227 and the outside world, the negative pressure disappears, and the adsorption is released. This can be achieved by the existing technology and will not be elaborated.

[0047] When one of the four groups of adsorption components is located at position a, the positions of the remaining three groups of adsorption components are respectively position b, position c and position d, wherein the adsorption component at position b is located above the side conveyor belt 212, and the adsorption component at position d is located above the synchronous belt 213. In addition, during operation, when the motor 225 drives the rotating seat 219 to rotate, the adsorption components pass through position a, position b, position c and position d in sequence. In addition, when the adsorption component rotates with the rotating seat 219, the speed of the adsorption component is composed of a tangential component speed and a radial component speed. When the direction of the tangential component speed of the adsorption component is consistent with the conveying direction of the main conveyor belt 100, the position of the adsorption component is named position e, and the tangential component speed of the adsorption component at position e is equal to the conveying speed of the main conveyor belt 100.

[0048] Reference Figure 6 The mounting frame 215 is slidably mounted with a lifting rod 1 220 and a lifting rod 221 in the vertical direction. A linear module 3 216 for driving the lifting rod 1 220 to move and a linear module 4 217 for driving the lifting rod 2 221 to move are mounted on the mounting frame 215. When the lifting rod 1 220 moves downward, it can simultaneously press the negative pressure tube 227 of the adsorption assembly at position a, position b, and position d to move downward. When the lifting rod 221 moves downward, it can press the negative pressure tube 227 of the adsorption assembly at position e to move downward.

[0049] Working principle of the present invention:

[0050] The eyeshadow boxes are placed one by one on the main conveyor belt 100 by using the existing robot technology, and then the main conveyor belt 100 pulls the eyeshadow boxes to move at a constant speed. During the constant speed movement, the eyeshadow boxes pass through multiple sets of placement mechanisms 200 in sequence, and the placement mechanisms 200 pull the powder cakes to fall into the corresponding positions in the eyeshadow boxes, thereby achieving the purpose of automated production;

[0051] The working process of the placement mechanism 200 is specifically manifested as follows:

[0052] The powder cake is placed on the feeding conveyor belt 201 by the existing technology, and is sent to the guide pipe 202 by the feeding conveyor belt 201, and is sent to the sub-conveyor belt 204 by the guide pipe 202 and the slide 203. Then, in the process of the sub-conveyor belt 204 pulling the powder cake to move, the powder cake is aligned by the cooperation of the two positioning plates 205. When the powder cake moves to the position a, it will be sensed by the laser sensor 211, and the sub-conveyor belt 204 will be paused;

[0053] At the same time, the lifting rod 1 220 is driven downward by the linear module 3 216, and the lifting rod 1 220 drives the adsorption components at positions a, b and d to move downward, wherein the adsorption component at position a will adsorb the powder cake with negative pressure. If the previous powder cake has defects, the adsorption component at position b will release the adsorption, so that the defective powder cake falls onto the side conveyor belt 212. If the previous powder cake is qualified, the adsorption component at position b will keep adsorption, and the negative pressure adsorption head 229 of the adsorption component at position d will be cleaned by the brush 214.

[0054] Then, the rotating seat 219 is driven to rotate by the second motor 225. When the adsorption component adsorbing the qualified powder cake rotates to the position e, the adsorption component releases the adsorption of the powder cake. At this time, the position corresponding to the powder cake in the eye shadow box is simultaneously located below the position e. Since the horizontal initial velocity of the powder cake is in the same direction and speed as the conveying velocity of the main conveyor belt 100 at this time, and since the adsorption component at the position e is driven to move downward by the cooperation of the fourth linear module 217 and the second lifting rod 221 at this time, the powder cake has an initial vertical velocity downward and is close to the eye shadow box. Therefore, the powder cake can be regarded as being relatively stationary with the eye shadow box and falls into the eye shadow box in a very short time.

[0055] Then, the adsorption component at position e continues to rotate to position d, and the above process is repeated to achieve uninterrupted and efficient delivery of the powder into the eye shadow box.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
