Description

Technical Field

[0001] The present invention relates to the technical field of yogurt lid packaging, and particularly to a milk cap pressing and feeding conveying device for yogurt lid packaging. Background Art

[0002] A yogurt lid is a lid used to seal a yogurt cup, usually made of materials such as plastic and aluminum foil. Its function is to prevent yogurt from being contaminated and deteriorated during storage and transportation, and at the same time, it is also convenient for consumers to open and drink. During the yogurt packaging process, it is generally necessary to press the milk cap onto the yogurt cup. This process is usually completed on an automated packaging production line, and specific equipment and processes are used to ensure that the milk cap can be tightly and evenly pressed onto the yogurt cup to ensure the sealing and integrity of the packaging. During the process of pressing the milk cap for yogurt lid packaging, the milk cap is generally conveyed by a feeding and conveying device.

[0003] In the prior art, when the milk cap pressing and feeding conveying device for yogurt lid packaging is working, generally, a vertical conveyor is used to initially convey the milk cap. When the milk cap moves to the curved track, the milk cap is blown into the curved milk cap for neat conveying by air flow. At this time, the milk cap pressing opening faces outward. When the milk cap slides to the end along the curved track, the milk cap pressing opening is at the bottom. Then, the milk cap is conveyed to the lid dividing turntable by a horizontal conveyor, which is convenient for the subsequent mechanical pressing disc to grab the milk cap and press it onto the top of the yogurt cup.

[0004] When the vertical conveyor is conveying the milk cap, there is an accidental situation where the milk cap is reversed, and its pressing opening faces the inside of the device. When it enters the curved track and slides to the end along the track, the milk cap pressing opening is at the top. Finally, the horizontal conveyor and the lid dividing turntable convey the reversed milk cap. The mechanical pressing disc is usually designed to grab the milk cap in the state where the milk cap pressing opening is at the bottom. When the milk cap is reversed, that is, the milk cap pressing opening is at the top, it is easy to cause the grabbing position of the grabbing device of the pressing disc to be inaccurate, or even unable to accurately grab the milk cap, increasing the probability of the milk cap falling during the grabbing process, which is not conducive to yogurt lid packaging and affects production efficiency and product quality.

[0005] Therefore, we propose a milk cap pressing and feeding conveying device for yogurt lid packaging to solve the problems raised in the above background art. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the present invention is in use, the multi-stage electric push rod drives the flip cover tube to move to the milk cap. The vacuum pump is started, and the suction cup adsorbs the milk cap. The multi-stage electric push rod drives the milk cap to move above the arc-shaped connecting track. The positive and negative motor rotates the flip cover tube, driving the milk cap to flip, so that its pressing opening rotates forward. Then, the hydraulic cylinder pushes the limit clip to clamp on both sides of the milk cap. The solenoid valve is opened, and the negative pressure disappears. At the same time, the multi-stage electric push rod pulls the moving part to move again, pulling the flip cover tube and the suction cup away from the milk cap. The milk cap drops downward into the arc-shaped connecting track and slides into the curved conveying track while keeping the pressing opening facing forward for continuous conveying. Under the action of the flip cover assembly, the effect of flipping the milk cap is achieved, turning the reversed milk cap into a state that meets the requirements, facilitating better subsequent conveying, and avoiding conveying milk caps that do not meet the requirements to the grasping device, affecting the subsequent grasping effect and packaging effect.

[0021] 2. When the present invention is in use, the first camera is started. When the pressing opening of the photographed milk cap faces forward, the hydraulic rod pulls the baffle upward. At the same time, the milk cap slides from the conveying mechanism into the curved conveying track and then slides onto the top of the conveyor belt of the horizontal conveyor body. When it is photographed that some milk caps are reversed, the first electric rotating mechanism and the hydraulic rod are started simultaneously. The hydraulic rod pushes the baffle to move downward again to block the milk cap. The first electric rotating mechanism drives the guide plate to quickly rotate into the guide track. The milk cap enters the guide track through the discharge hole. Under the action of the material distribution assembly, the state of the milk cap is detected and material is distributed to ensure that the milk caps with the pressing opening facing forward accurately slide into the curved conveying track for conveying.

[0022] 3. When the present invention is in use, the second camera photographs the milk cap. When the state of the photographed milk cap does not meet the requirements, the second electric rotating mechanism is started. The rotation of the adjusting roller drives the milk cap to rotate and adjusts its angular position. When the second camera photographs that it rotates into a state that meets the requirements, the second electric rotating mechanism automatically closes, thus achieving the effect of adjusting the angle of the milk cap, facilitating the subsequent accurate movement of the two flip cover tubes to the upper and lower positions of the milk cap, accurately adsorbing it, and helping it to flip better subsequently.

[0038] In this embodiment, during use, the vertical conveyor body 101, the horizontal conveyor body 102, the first camera 206, the conveying mechanism 203, the first electric rotating mechanism 207, the hydraulic rod 209, the second camera 301, the second electric rotating mechanism 302, the cylinder 304, the forward and reverse motor 405, the solenoid valve 412, the hydraulic cylinder 415, the multi-stage electric push rod 419, and the third electric rotating mechanism 5 are all electrically connected to an external PLC control system. The six limit rods 305 are grouped into two groups of three each. One group of limit rods 305 on the left extends into the inside of the material guiding track 401, and the tops of the group of limit rods 305 on the right are movably inserted into the inside of the limit holes 422, as Figure 9 shown. Start the vertical conveyor body 101, and slowly convey the milk cap with the crimping opening facing outward upward to the blowing port 105. One end of the blowing pipe 104 is connected to an external blowing device, and compressed gas is blown by the blowing device to the blowing port 105, so as to blow the milk cap conveyed here into the material distribution assembly 2 for milk cap detection and material distribution operations. The individual milk caps that are reversed slide into the material guiding track 401 through the discharge holes 212. Under the action of the right limit rod 305, the milk caps slide to the outlet of the material guiding track 401, as Figure 9 shown. At the same time, the adjustment assembly 3 detects and rotates and adjusts the milk caps with the crimping opening facing backward. When the milk caps are adjusted to be as Figure 9After the state shown, the left cylinder 304 starts, and the multi-stage electric push rod 419 starts simultaneously. At this time, the right limit rod 305 moves upward to the right side of the milk cap. The left cylinder 304 pulls the left limit rod 305 downward into the limit hole 422. The multi-stage electric push rod 419 pushes the moving part 404 to move to the right, and pushes the forward and reverse motor 405, the fixed plate 406 and the two flap tubes 407 to move together. At the same time, it drives the three-way pipe 409 to slide from the arc hole 413 to one of the slide holes 414, so that the two flap tubes 407 move from the flap cylinder 402 to the material guiding track 401 and are stuck at the upper and lower parts of the milk cap. At this time, the upper, middle and lower three suction cups 408 are respectively located at the upper and lower parts of the milk cap. One end of the hose 410 is connected to an external vacuum pump. The vacuum pump is started to pump out the air between the suction cup 408 and the milk cap, so that a negative pressure is generated between the suction cup 408 and the milk cap, thereby adsorbing the milk cap between the two flap tubes 407. Then the multi-stage electric push rod 419 starts again, pulls the moving part 404 to move reversely and reset, and pauses for a while, driving the fixed plate 406 and the flap tube 407 to move reversely, so that the adsorbed milk cap moves into the flap cylinder 402 and is located above the arc connecting track 403. At the same time, the three-way pipe 409 slides into the arc hole 413 again. Then the forward and reverse motor 405 starts, drives the fixed plate 406 and the flap tube 407 to rotate, drives the adsorbed milk cap to flip, and at the same time drives the three-way pipe 409 to rotate inside the arc hole 413. When the forward and reverse motor 405 automatically pauses, the milk cap is flipped one circle and its crimping mouth rotates forward. Then the hydraulic cylinder 415 starts, pushes the limit clamp 416 to move from the embedded hole 417 into the inside of the flap cylinder 402 and is stuck on both sides of the milk cap to limit the flipped milk cap to prevent it from continuing to move with the flap tube 407 later and affecting its sliding into the arc connecting track 403. Then the external vacuum pump is turned off, and at the same time the solenoid valve 412 is opened, and air enters the three-way pipe 409 through the air inlet pipe 411, so that the negative pressure between the suction cup 408 and the milk cap disappears. At the same time, the multi-stage electric push rod 419 also starts again, pulls the moving part 404 and the fixed plate 406 to continue moving to the left, the three-way pipe 409 slides into another slide hole 414, and the movement of the fixed plate 406 drives the flap tube 407 and the suction cup 408 to leave from the upper and lower parts of the milk cap. At this time, the milk cap falls downward into the arc connecting track 403 under the action of gravity and slides along the arc connecting track 403 to the curved conveying rail 202 to continue conveying while keeping the crimping mouth facing forward.Under the action of the flip cover assembly 4, the milk cap is flipped over to achieve the effect of flipping, so that the inverted milk cap is flipped into a state that meets the requirements, which is convenient for subsequent better transportation and avoids the transportation of milk caps that do not meet the requirements to the grabbing device, which affects the subsequent grabbing effect and packaging effect. It solves the problem that when the feeding and conveying equipment transports the milk cap, some milk caps are in a reversed state, which will cause the inverted milk caps to be finally transported to the grabbing device, which is easy to cause inaccurate grabbing position, or even unable to accurately grab the milk cap, increasing the probability of the milk cap falling off, which is not conducive to the packaging of yogurt caps and affects the production efficiency and product quality.

[0039] Embodiment 2: Figures 1-2 and Figures 4-8 As shown, the material distribution component 2 includes a material distribution box 201, a curved conveying rail 202 is fixedly connected to the edge of the bottom of the material distribution box 201, a conveying mechanism 203 is arranged inside the material distribution box 201, a discharge hole 212 is opened at the bottom of the material distribution box 201, one end of the arc-shaped connecting track 403 is fixedly connected to the outer surface of the curved conveying rail 202, the other end of the guide track 401 is fixedly connected to the bottom of the material distribution box 201 near the discharge hole 212, one side outer surface of the flip cover cylinder 402 and the other end of the multi-stage electric push rod 419 are fixedly mounted on one side outer surface of the vertical conveyor body 101, the material distribution component 2 also includes a first camera 206 and a hydraulic rod 209, a baffle 210 is fixedly mounted on the bottom end of the hydraulic rod 209, and a transparent plate 2 is arranged on the top of the material distribution box 201 04. A movable hole 211 is provided at one side of the top of the material distribution box 201, a first electric rotating mechanism 207 is arranged at the bottom of the front surface of the material distribution box 201, a material guide plate 208 is arranged on the outer surface of the first electric rotating mechanism 207, and the outer surface of the material guide plate 208 is movably embedded in the inside of the discharge hole 212, a mounting plate 205 is fixedly installed at one side of the top of the material distribution box 201, the top of the first camera 206 and the top of the hydraulic rod 209 are both fixedly installed on the top surface inside the mounting plate 205, the outer surface of the baffle 210 is movably embedded in the inside of the material distribution box 201, the outer surface of the hydraulic rod 209 is movably embedded in the movable hole 211, a third electric rotating mechanism 5 is arranged on the outer surface of the curved conveying rail 202, and a toggle bar 6 is arranged on the outer surface of the third electric rotating mechanism 5.

[0040] In this embodiment, when in use, the milk caps are blown into the material distribution box 201 through the conveying assembly 1. Under the blocking effect of the baffle 210, the milk caps are arranged in sequence on the conveyor belt surface of the conveying mechanism 203. Figure 6As shown. Start the first camera 206 in advance, take an image of the milk cap on the right side of the material distribution box 201 through the transparent plate 204, and transmit the captured image information to the external PLC control system for identification and comparison. When the pressure mouth of the milk cap photographed faces forward, it means that the position of the milk cap is correct. At this time, the hydraulic rod 209 is started, pulling the baffle 210 to move upward to the moving hole 211, and at the same time, the conveying mechanism 203 is started to drive the milk cap to move to the right. At this time, the milk cap slides from the discharge end of the conveying mechanism 203 to the curved conveying rail 202, and slides along the curved conveying rail 202 to the horizontal conveyor body 102. When the milk cap slides to the tail end of the curved conveying rail 202, the milk cap will become a state with the pressure mouth facing forward, and then slide to the top of the conveyor belt of the horizontal conveyor body 102 for transportation. When the first camera 206 captures that some milk caps are turned upside down with the pressing opening facing backward, the first electric rotating mechanism 207 and the hydraulic rod 209 are activated simultaneously, and the hydraulic rod 209 pushes the baffle plate 210 to move downward again to block the milk caps and prevent the turned-up milk caps from accidentally sliding into the curved conveying track 202. The first electric rotating mechanism 207, the second electric rotating mechanism 302 and the third electric rotating mechanism 5 are all composed of motors and rotating shafts, which are existing mature technologies and will not be described in detail here. The first electric rotating mechanism 207 also drives the guide plate 208 to rotate quickly to the inside of the guide track 401, such as Figure 8 As shown, the reversed milk cap moved to this place enters the guide track 401 through the discharge hole 212, the position of the milk cap is adjusted by the adjustment component 3, and then the reversed milk tea is turned over by the flip cover component 4 so that its pressure mouth faces the front. When it is detected that the milk cap meets the conveying requirements, the first electric rotating mechanism 207 drives the guide plate 208 to turn over to the discharge hole 212, and the hydraulic rod 209 pulls the baffle 210 to move upward again without affecting normal conveying. Under the action of the material dividing component 2, the state of the milk cap is detected and the material is divided to ensure that the milk cap with the pressure mouth ahead accurately slides into the curved conveying track 202 for conveying. The third electric rotating mechanism 5 is started to drive the toggle bar 6 to rotate, and the milk cap accidentally stuck at the connection between the arc-shaped connecting track 403 and the curved conveying track 202 can be toggled downward, pushing it to continue sliding and conveying along the curved conveying track 202.

Two cylinders 304 are installed at the bottom of the second electric rotating mechanism 302 through an auxiliary frame. Three limiting rods 305 are fixedly installed at the top ends of the two cylinders 304. A transparent detection plate 420 is arranged at the top of the material guiding track 401. The top of the second camera 301 is fixedly installed at the bottom of the material distribution box 201. A rotating hole 421 is opened at the bottom of the material guiding track 401. Six limiting holes 422 are opened at the bottom of the material guiding track 401 near the rotating hole 421. The second electric rotating mechanism 302 is installed at the bottom of the material guiding track 401 through an auxiliary plate. The outer surface of the adjustment roller 303 is movably embedded in the interior of the rotating hole 421. The outer surfaces of the six limiting rods 305 are respectively movably embedded in the six limiting holes 422.

[0042] In this embodiment, during use, after the inverted milk cap is conveyed to the material guiding track 401 through the material distribution component 2, under the limiting action of the left limiting rod 305, the milk cap slides to the outlet of the material guiding track 401. Then, the right cylinder 304 is started to push the right limiting rod 305 to move upward. At this time, the limiting rods 305 on both the left and right sides limit the milk cap. At the same time, the second camera 301 takes a picture of the milk cap through the transparent plate 204. When the milk cap conforms to Figure 9 the state in, the left cylinder 304 is started to pull the left limiting rod 305 to move downward. Then, the flip cover component 4 is started. When it is detected that the state of the milk cap does not conform to that in Figure 9 , that is, the arc surface in front of the milk cap faces upward or is inclined and the arc surface is not located on both sides, the second electric rotating mechanism 302 is started to drive the adjustment roller 303 to rotate. The milk cap contacts the adjustment roller 303, and the rotation of the adjustment roller 303 drives the milk cap to rotate to adjust its angular position. When the second camera 301 takes a picture of it rotating into the state in Figure 9 , the second electric rotating mechanism 302 automatically shuts down, so as to achieve the effect of adjusting the angle of the milk cap, which is convenient for the subsequent two flip tubes 407 to accurately move to the upper and lower positions of the milk cap and can accurately adsorb it to help it flip better subsequently.

[0043] The effects achieved by the entire mechanism and its working principle are as follows: Start the vertical conveyor body 101, slowly convey the milk cap with the crimping opening facing outward upward to the blowing port 105. The blowing device blows compressed gas into the blowing pipe 104, and blows the milk cap conveyed here through the blowing port 105 into the distributing box 201. Under the blocking effect of the baffle 210, the milk caps are arranged in sequence on the surface of the conveyor belt of the conveying mechanism 203. Start the first camera 206 in advance, take an image of the milk cap on the right side in the distributing box 201, and transmit the captured image information to the external PLC control system for identification and comparison. When the crimping opening of the captured milk cap faces forward, it means the position of the milk cap is correct. At this time, the hydraulic rod 209 is activated, pulling the baffle 210 upward to move into the moving hole 211. At the same time, the conveying mechanism 203 is activated, driving the milk cap to move to the right and slide into the curved conveying track 202. When the milk cap slides to the end of the curved conveying track 202, the milk cap will change to the state with the crimping opening facing a certain direction, and then slide onto the top of the conveyor belt of the horizontal conveyor body 102. When the first camera 206 captures that some milk caps are reversed and the crimping opening faces backward, the first electric rotating mechanism 207 and the hydraulic rod 209 are activated simultaneously. The hydraulic rod 209 pushes the baffle 210 to move downward again to block the milk cap. The first electric rotating mechanism 207 drives the guide plate 208 to rotate quickly into the guide track 401. The milk cap enters the outlet of the guide track 401 through the discharge hole 212. The second camera 301 takes a picture of the milk cap. When the milk cap meets the Figure 9 state, the left cylinder 304 is activated, pulling the left limiting rod 305 downward, and then the flip assembly 4 is activated. When it is captured that the state of the milk cap does not conform to that in Figure 9 , the second electric rotating mechanism 302 is activated, driving the milk cap to rotate through the adjusting roller 303 to make it rotate into Figure 9When in the state in []. Then the left cylinder 304 starts to pull the limit rod 305 to move downward, and the multi-stage electric push rod 419 starts at the same time, pushing the moving part 404, the forward and reverse motor 405 and the fixed plate 406 to move, so that the two flip tubes 407 move to the upper and lower positions of the milk cap. The vacuum pump is started to suck out the air between the suction cup 408 and the milk cap, so as to adsorb the milk cap between the two flip tubes 407. Then the multi-stage electric push rod 419 starts again, pulling the moving part 404 to move in the reverse direction and reset, and pausing for a while, so that the adsorbed milk cap moves into the flip tube 402. Then the forward and reverse motor 405 starts, driving the fixed plate 406 and the flip tube 407 to rotate, driving the adsorbed milk cap to flip. When the forward and reverse motor 405 automatically pauses, the milk cap is flipped one circle, and its crimping mouth rotates forward. Then the hydraulic cylinder 415 starts, pushing the limit clamp 416 to clamp on both sides of the milk cap. Then the external vacuum pump is turned off, and at the same time the solenoid valve 412 is opened, the negative pressure disappears, and at the same time the multi-stage electric push rod 419 also starts again, pulling the moving part 404 and the fixed plate 406 to continue moving to the left, driving the flip tube 407 and the suction cup 408 to leave from the upper and lower positions of the milk cap. Under the action of gravity, the milk cap falls downward into the arc connecting track 403, and slides along the arc connecting track 403 to the curved conveying track 202 in the state of keeping the crimping mouth forward for continuous conveying.
