Detailed Implementation

[0031] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0032] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0033] like Figures 1 to 3 As shown, the inclined conveyor for canned food packaging according to a preferred embodiment of the present invention includes a conveyor 1 and a packaging conveying device 2. The conveyor 1 includes a support frame 101, a drive device 102 and a conveyor belt 103, so that the finished canned food is conveyed on the conveyor belt 103 to the box.

[0034] However, it should be noted that one end face of the conveyor 1 is set with an inclination angle of 50-30°. With the assistance of the inclination, the cans are more likely to enter the connecting plate 2032 of the can conveying operation table 203 for automatic packing during the conveying process of the cans on the conveyor belt 103.

[0035] The inclined angle of one end face of the conveyor 1 is preferably 30°.

[0036] The packaging and conveying device 2 includes a support operating platform 201, a protective plate closing mechanism 3, a can conveying device 5, an anti-static device 6, a can conveying delay mechanism 9, and a packaging box roller conveyor 8. The packaging and conveying device 2 automatically packs the cans into boxes after they enter the can conveying operating platform 203.

[0037] The top end face of the supporting operating platform 201 is welded with a can conveying operating platform 203 and a packaging operating platform 202. The can conveying operating platform 203 is located on the inner bottom end face of the packaging operating platform 202. A top cover 2031 is fixedly connected to the can conveying operating platform 203, and a connecting plate 2032 is fixedly connected to the top cover 2031. The connecting plate 2032 matches the conveyor belt 103 and is located on the lower end face of the inclined end face of the conveyor belt 103, so that the cans are conveyed to the upper end face of the connecting plate 2032 through the conveyor belt 103.

[0038] It should be noted that there is a gap between the connecting plate 2032 and the conveyor belt 103. The connecting plate 2032 does not affect the normal use of the conveyor 1. Similarly, the gap between the connecting plate 2032 and the conveyor belt 103 does not affect the canned food entering the end face of the connecting plate 2032 for packing.

[0039] A first groove 20311 is provided on the can conveying operating table 203. A protective plate 7 is engaged in the first groove 20311. The first groove 20311 matches the protective plate 7. In the initial state of the protective plate 7, the cans enter the connecting plate 2032 sequentially through the conveyor belt 103. Under the action of the conveyor belt 103, they enter the top end face of the protective plate 7 again.

[0040] It should be noted that this refers to the initial state, i.e., the state in which the protective plate 7 is not under any force.

[0041] like Figure 3 As shown, the protective plate closing mechanism 3 includes a drive motor 304, a lead screw 301 and multiple movable connecting plates 303. The movable connecting plates 303 are fixedly connected to the protective plate 7. The protective plate closing mechanism 3 is located on the top end face of the support operating table 201, that is, the protective plate closing mechanism 3 is located on one side end face of the protective plate 7.

[0042] Multiple movable connecting plates 303 are provided with first limiting holes that match the lead screw 301. A pair of opposite end faces of the lead screw 301 are connected to support seats 302. A pair of support seats 302 are provided with second limiting holes that match the lead screw 301. One end face of the lead screw 301 is connected to a drive motor 304, so that the lead screw 301 can be rotated by the drive motor 304, thereby moving the protective plate 7.

[0043] The diameter of the first limiting hole is larger than the diameter of the lead screw 301, so as to facilitate the rotation of the lead screw 301 on the first limiting hole and the support seat 302.

[0044] A pair of fixed posts 305 are fixedly connected between each pair of support seats 302. The fixed posts 305 pass through multiple movable connecting plates 303. The pair of fixed posts 305 are located on a pair of opposite end faces of the lead screw 301.

[0045] A pair of lead screws 301 are fixedly connected to the top end face of the support operating table 201, that is, a pair of lead screws 301 are fixed to the top end face of the support operating table 201 by bolts.

[0046] Multiple movable connecting plates 303 are provided with second limiting holes that match the fixed posts 305. The fixed posts 305 pass through the second limiting holes, so that the movable connecting plates 303 can slide on the fixed posts 305.

[0047] The can conveying operating table 203 is provided with a sliding groove that matches the protective plate 7. Multiple movable connecting plates 303 are fixedly connected with movable connecting plates that match the sliding groove. The protective plate 7 is fixedly connected to the other end face of the movable connecting plate. When the movable connecting plate 303 moves, it drives the protective plate 7 to move. When the drive motor 304 starts and drives the lead screw 301 to rotate, it drives the movable connecting plate 303 and the protective plate 7 to move, thus controlling the opening and closing of the first groove 20311.

[0048] Specifically, after the cans enter the protective plate 7 on the top end face of the cover 2031, the can conveying device 5 picks up the cans to be packed and fixes them. At this time, the drive motor 304 starts and controls the protective plate 7 to move away from the end face of the first groove 20311, so that the multiple cans picked up by the can conveying device 5 descend and move to the inner end face of the can conveying operating table 203. The cans to be packed enter the packaging box 4. After the packing is completed, the can conveying device 5 is reset, and at the same time the drive motor 304 is started to reset the protective plate 7.

[0049] like Figures 5 to 9As shown, the can conveying device 5 includes a cylinder 501 and a vacuum pump 502. The cylinder 501 is fixed to the top end face of the packaging operation platform 202 by bolts. The cylinder 501 includes a multi-stage telescopic rod 508, and a fixed plate 507 is fixedly connected to the bottom end face of the multi-stage telescopic rod 508. That is, a base plate is connected to the bottom end face of the multi-stage telescopic rod 508, and the base plate and the fixed plate 507 are fixed together by bolts, so that the cylinder 501 controls the raising and lowering of the fixed plate 507.

[0050] like Figures 7 to 11 As shown, a pair of negative pressure conveying pipes 504 are welded to the bottom end face of the fixed plate 507. Multiple suction cups 505 are fixedly connected to the bottom end face of the negative pressure conveying pipes 504. The multiple suction cups 505 are used to adsorb canned food.

[0051] Each pair of negative pressure conveying pipes 504 is connected to a second negative pressure conveying pipe 5012, and each pair of negative pressure conveying pipes 504 is connected to the second negative pressure conveying pipe 5012.

[0052] One end face of the second negative pressure conveying pipe 5012 is connected to the first negative pressure conveying pipe 5011. The second negative pressure conveying pipe 5012 is connected to the first negative pressure conveying pipe 5011. The vacuum pump 502 includes an outlet conveying pipe 5021 and an inlet conveying pipe 5013. The first negative pressure conveying pipe 5011 is connected to the inlet conveying pipe 5013. The first negative pressure conveying pipe 5011 passes through the packaging operation table 202. When the vacuum pump 502 is started, negative pressure is conveyed through the inlet conveying pipe 5013. The negative pressure is transmitted to the negative pressure conveying pipe 504 through the first negative pressure conveying pipe 5011 and the second negative pressure conveying pipe 5012 in sequence. Finally, the negative pressure is output through multiple suction cups 505 to adsorb the cans located at the bottom end face of the negative pressure conveying pipe 504.

[0053] A suction cup protective plate 506 is provided on the bottom end face of a pair of negative pressure conveying pipes 504. Multiple connecting plates 503 are fixedly connected between the negative pressure conveying pipes 504 and the suction cup protective plate 506. The suction cup protective plate 506 is fixed to the bottom end face of the fixed plate 507 through the connecting plates 503. Of course, the connecting plates 503 and the multiple suction cups 505 are staggered and do not affect each other.

[0054] The suction cup protective plate 506 has a limiting groove 5061 that matches multiple suction cups 505, and the multiple limiting grooves 5061 are used to place the suction cups 505.

[0055] The bottom end face of suction cup 505 is lower than the bottom end face of suction cup protective plate 506, which facilitates suction cup 505 to perform adsorption operations.

[0056] like Figures 1 to 4As shown, the packaging box roller conveyor 8 is located on the bottom end face of the can conveying operating platform 203, that is, the packaging box roller conveyor 8 is located on the middle end face of the bottom of the packaging operation operating platform 202, supporting the upper end face of the operating platform 201. There is a gap between the supporting operating platform 201 and the packaging box roller conveyor 8, and the two operate without interfering with each other.

[0057] The packaging box roller conveyor 8 is used to transport the packaging boxes 4. When in use, the packaging box roller conveyor 8 is started, and the packaging boxes 4 to be packed are placed on the upper end face of the packaging box roller conveyor 8. The packaging boxes 4 are then transported to the bottom end face of the top cover 2031 for automatic packing.

[0058] It is worth noting that when the can conveying device 5 starts to pack the cans into the packaging box 4 at the bottom end of the cover 2031, its packaging box roller conveyor 8 is in a stopped state. After the can conveying device 5 finishes packing, the packaging box roller conveyor 8 starts to transport the packaging box 4 to the next process.

[0059] Furthermore, one of the suction cups 505 is equipped with a vacuum pressure sensor to monitor the adsorption status of the suction cup 505. The detection pressure value is preset before use; it should be noted that the detection pressure value is generally set to -60 kPa to 160 kPa. The vacuum pressure sensor monitors the pressure during suction by the suction cup 505. If insufficient pressure is detected, a signal is output to promptly increase the vacuum pressure in the suction cup tubing. If no adsorption occurs for an extended period, an alarm is triggered to alert the operator.

[0060] The vacuum pressure sensor is preferably a capacitive vacuum sensor.

[0061] Multiple displacement sensors are installed on the can conveying operating platform 203, namely, a pair of displacement sensors are installed on the bottom and top end faces of the can conveying operating platform 203 to monitor the position of the cans or packaging boxes 4. When the can enters the designated position on the protective plate 7, or when the packaging box 4 enters the designated position on the bottom end face of the can conveying operating platform 203, a signal is output to promptly start the can conveying device 5 to begin the adsorption work and adsorb and fix multiple cans.

[0062] After adsorption is completed, the protective plate closing mechanism 3 is activated, controlling the protective plate 7 to move out of 50311. The can conveying operation table 203 is equipped with a displacement sensor on the end face near the protective plate 7, which is used to monitor the cans adsorbed by the can conveying device 5 after they enter the packaging box 4 and start to move upwards until they leave the first groove 20311. Then, the protective plate closing mechanism 3 is activated to reset the protective plate 7, and so on.

[0063] Preferably, the can conveying device 5 currently installed can pack 6 cans of food at the same time, and the number and size of the suction cups 505 can also be adjusted as needed.

[0064] like Figures 5 to 9 As shown, the vacuum pump 502 is fixedly connected to the top end face of the packaging operation platform 202 by bolts, and the can conveying delay mechanism 9 is connected to the vacuum pump 502.

[0065] The canned food conveying delay mechanism 9 includes a second airflow pipe 901 and a plurality of first nozzles 903, which are located on the end face near the connecting plate 2032.

[0066] The air outlet delivery pipe 5021 is connected to the first airflow pipe 5022, and the first airflow pipe 5022 is connected to the second airflow pipe 901. Multiple first nozzles 903 are fixedly connected to the bottom end face of the second airflow pipe 901. Multiple second connecting columns 902 are fixedly connected between the second airflow pipe 901 and the packaging operation platform 202. The can conveying delay mechanism 9 is located at the upper part near the inclined end face of the conveyor belt 103.

[0067] It should be noted that the bottom end face of the first nozzle 903 is set with an inclination of 40-60°. The inclination end face of the first nozzle 903 is close to the conveyor belt 103, and the bottom end face of the first nozzle 903 is 150-260mm away from the top end face of the can conveying operating platform 203. This allows the first nozzle 903 to be close to the cans being conveyed on the conveyor belt 103, but does not affect the normal conveying of the cans.

[0068] Specifically, the airflow generated by the adsorption during the operation of cylinder 501 is transported to the first airflow pipeline 5022 through the air outlet delivery pipe 5021, and then enters the second airflow pipeline 901. It is then sprayed through multiple first nozzles 903. The sprayed airflow creates effective resistance to the cans located on the connecting plate 2032. That is, while the can conveying device 5 is adsorbing and fixing the cans located on the protective plate 7 for packaging, the airflow sprayed by the first nozzles 903 blocks the subsequent conveyed cans, preventing the cans from entering the protective plate 7 and affecting the adsorption work in progress.

[0069] It should be noted that when the cylinder 501 is running, its negative pressure value is between -60 kPa and 160 Pa. The air pressure discharged through the air outlet conveying pipe 5021 is sufficient to create effective resistance to the subsequent conveying of cans, preventing them from moving.

[0070] The bottom end face of the second airflow duct 901 is provided with an interceptor plate assembly 904, which includes a plurality of second nozzles 9041. The bottom end face of the second airflow duct 901 is provided with a plurality of second nozzles 9041. The second airflow duct 901 is provided with a first delivery pipe and a second delivery pipe, and the first delivery pipe is connected to the first nozzle 903.

[0071] The second delivery pipe is connected to the second nozzle 9041. Multiple tension springs 9042 are installed on the adjacent end faces of the multiple second nozzles 9041 in the second airflow pipe 901. An interceptor plate 9043 is fixedly connected to the bottom end face of each of the multiple tension springs 9042; that is, the interceptor plate 9043 is welded to the bottom end face of the multiple tension springs 9042. This allows the can conveying device 5 to simultaneously increase resistance to the subsequent conveying of cans while adsorbing and packing cans located on the protective plate 7.

[0072] It is worth noting that the wind force output by the tension spring 9042 is sufficient to cause the interceptor plate 9043 to be lowered by the force.

[0073] Specifically, when the can conveying device 5 is in adsorption operation, the second nozzle 9041 starts to operate and delivers airflow downwards. Under the action of the airflow, the tension spring 9042 is forced to extend downwards, thereby driving the interceptor plate 9043 to move downwards. Under the continuous action of the second nozzle 9041, the interceptor plate 9043 descends to the upper end face of the can on the upper cover 2031, which strengthens the obstruction of the conveyed can and prevents the can from moving forward, thus ensuring the normal operation of the can conveying device 5.

[0074] Preferably, a second solenoid valve is connected to the second conveying pipe to control the opening and closing of the second conveying pipe. Specifically, when the can conveying device 5 finishes adsorption, the second solenoid valve starts to close the second conveying pipe, so that the second nozzle 9041 stops conveying air and the interceptor plate 9043 resets.

[0075] A first solenoid valve is connected to the first conveying pipe to control the air flow rate inside the first conveying pipe. The first solenoid valve includes a valve. When the can conveying device 5 finishes adsorption, the first solenoid valve closes part of the valve to reduce the air flow rate inside the first conveying pipe, so that the airflow output does not affect the normal operation of the can, and can also remove dust, impurities and other contaminants from the surface of the can.

[0076] In the initial state, the interceptor plate 9043 is located on one side of the bottom of the first nozzle 903. The interceptor plate 9043 does not affect the normal delivery of the canned goods. In the initial state, that is, the second nozzle 9041 is not turned on.

[0077] like Figures 9 to 11As shown, the static eliminator 6 includes a first ion fan 601 and a bottom static eliminator 604. The first ion fan 601 is connected to one side of the packaging operation platform 202, that is, the first ion fan 601 is fixed to one side of the support platform 201 by bolts. The first ion fan 601 includes multiple first air outlets. The first ion fan 601 can deliver ion air to eliminate the static electricity generated by the packaging boxes 4 conveyed on the packaging box roller conveyor 8.

[0078] The bottom static elimination device 604 is located on the bottom end face of the support operating table 201, and reaches the bottom end face of the packaging box 4 conveyed on the packaging box roller conveyor 8 to eliminate the static electricity generated thereon.

[0079] The bottom of the first air outlet on a pair of opposite end faces of the first ion fan 601 is connected to a first ion air conveying pipe 602, that is, the first ion air conveying pipe 602 is tightly attached to the bottom end face of the first ion fan 601, and the two are fixed together by adhesive. The first ion air conveying pipe 602 is fixed to the packaging operation table 202 by bolts.

[0080] The bottom end face of the first ion air conveying pipe 602 is fixedly connected to the second ion air conveying pipe 603. Both the first ion air conveying pipe 602 and the second ion air conveying pipe 603 are fixedly connected to the packaging operation table 202. The first ion air conveying pipe 602, the first ion fan 601 and the second ion air conveying pipe 603 are connected. The second ion air conveying pipe 603 has multiple second air outlets, so that the first ion air conveying pipe 602 collects the ion air conveyed by the first ion fan 601 and conveys it into the second ion air conveying pipe 603. The ion air is then sprayed through the multiple second air outlets to eliminate the static electricity generated on the periphery of the packaging box 4 that passes through the second ion air conveying pipe 603.

[0081] The support operating platform 201 has a second groove on the bottom end face of the can conveying operating platform 203.

This allows the ionized air output by the second ion fan 6042 to be blown through the second groove towards the bottom end face of the packaging box 4, eliminating static electricity on the packaging box 4.

[0083] When using, such as Figure 1 and Figure 8As shown, when the cans enter the upper end face of the connecting plate 2032 via the conveyor belt 103, under the output force of the conveyor belt 103, the cans sequentially enter the top end face of the protective plate 7 on the can conveying operating platform 203. When all 6 cans have entered the upper end face of the protective plate 7, the can conveying device 5 starts to operate, the cylinder 501 and the vacuum pump 502 are started, the cylinder 501 operates to control the fixed plate 507 to move downwards until the suction cup 505 adsorbs the cans, the protective plate closing mechanism 3 is started, the drive motor 304 controls the lead screw 301 to rotate and drive the moving connecting plate 303 and the protective plate 7 to move away from the end face of the first groove 20311.

[0084] The cylinder 501 restarts and controls the fixed plate 507 to move downwards to the suction cup 505. Multiple cans are then drawn into the packaging box 4 for packing. After packing is completed, the fixed plate 507 is reset, and the protective plate closing mechanism 3 is activated, controlling the protective plate 7 to reset. The packaging box roller conveyor 8 starts running, controlling the packed packaging box 4 to be transported to the next process, and so on.
