Detailed implementation manners

[0022] As Figures 1 to 3 shown, the snail rice noodle barrel sorting robot of the present invention includes a barrel sorting device and a disk-type feeding bin, and the disk-type feeding bin is connected to the rear end of the barrel sorting device.

[0023] As Figure 1 , 2 shown, the barrel sorting device includes a barrel, a feeding hopper, a barrel rotating assembly, a base, a belt support, a feeding belt, a belt driving motor, and a brushing device. Axial ribs are uniformly arranged on the inner surface of the barrel, and the axial ribs are connected to the inner surface of the barrel at equal intervals by welding. One end (front end) of the barrel is connected to the feeding hopper and can rotate relative to the feeding hopper, and a through hole is provided at the other end (rear end) of the barrel. The barrel rotating assembly is connected to the base, and the barrel is positioned on the barrel rotating assembly and can be driven by the barrel rotating assembly to rotate. The bottom end of the belt support is fixed on the base, one end of the upper side of the belt support extends forward through the through hole at the rear end of the barrel into the barrel, and the other end of the upper side of the belt support extends backward above the feeding port of the disk-type feeding bin. The feeding belt is connected to the belt pulleys at the front and rear ends of the belt support, the belt driving motor is arranged on one side of the belt support and drives the belt pulley to drive the feeding belt to rotate in a cycle, and the brushing device is arranged on both sides of the feeding belt inside the barrel and is installed on the belt support.

[0024] The drum rotation assembly includes a disc barrel belt, a driving wheel, a tensioning wheel, and a disc barrel motor. As Figure 1 shown, the driving wheel and the tensioning wheel are respectively mounted on the upper surface of the base through mounting brackets I. The disc barrel motor is mounted on the upper surface of the base through mounting bracket II and is located on one side of the driving wheel. The output shaft of the disc barrel motor is connected to one end of the driving wheel through a coupling. The disc barrel belt is connected to the outer surface of the drum and is respectively connected to the surface of the driving wheel and the surface of the tensioning wheel. When the disc barrel motor works, it drives the driving wheel to rotate, and the driving wheel drives the drum to rotate through the disc barrel belt. Mounting brackets III are respectively connected to the front and rear sides of the mounting bracket I on the upper surface of the base. Each group of mounting brackets III includes two support arms. One support arm extends vertically upward from the upper surface of the base to one side of the drum near the bottom, and the other support arm first extends vertically upward from the upper surface of the base and then continues to bend upward along the outer surface of the drum to the upper end of the outer side of the drum top. Rollers capable of guiding the rotation of the drum are respectively connected to the ends of the two support arms.

[0025] In this embodiment, the brushing device includes a side brushing assembly and an inclined brushing assembly. The side brushing assembly and the inclined brushing assembly are respectively mounted on the upper ends of both sides of the belt bracket extending into the inner side of the drum in a front-to-back arrangement. The side brushing assembly includes two side brushing rollers and a side brushing driving motor respectively connected to the ends of the rotating shafts of the two side brushing rollers. A pair of connecting supports I are respectively connected to the upper ends of both sides of the belt bracket extending into the inner side of the drum. The rotating shafts of the two side brushing rollers are respectively supported by the corresponding connecting supports I. When the side brushing driving motor works, it drives the two side brushing rollers to rotate relative to the connecting supports I. The inclined brushing assembly includes two inclined brushing rollers and an inclined brushing driving motor respectively connected to the ends of the outer rotating shafts of the two inclined brushing rollers. Connecting supports II are respectively connected to the upper ends of both sides of the belt bracket behind the connecting supports I. The outer rotating shafts of the two inclined brushing rollers are respectively supported by the connecting supports II. The inner sides of the two inclined brushing rollers respectively extend inwardly and obliquely to the middle of the feeding belt. When the inclined brushing driving motor works, it drives the two inclined brushing rollers to rotate relative to the corresponding connecting supports II.

[0026] The working principle of the drum stock arranging is as follows: After the material package enters through the feeding hopper, it falls to the bottom inside the drum. The drum motor drives the drum to rotate. At this time, the material packages at the bottom of the drum have two moving states: One is the material packages that fall into the grooves formed by adjacent axial ribs. Due to the restraint of the axial ribs, they rotate with the drum to a higher position and then fall onto the feeding belt under the action of gravity; The other is the material packages floating on the upper layer. Due to the relatively small interlayer friction, the height they rise with the rotation of the drum is limited. After reaching a certain height, they slide down under the action of gravity and move towards the lower bottom of the drum. The drum rotates continuously. As a result, the material packages that fall into the grooves formed by adjacent axial ribs fall onto the feeding belt to achieve the effect of preliminary stock arranging; The material packages fall on the feeding belt and move forward under the action of the belt driving motor. At the same time, the material packages on both sides of the feeding belt fall back to the bottom of the drum driven by the rotational power of the side brush rollers. If there are stacked material packages on the feeding belt, when they move forward to the inclined brush roller, they also fall back to the bottom of the drum driven by the rotation of the inclined brush roller, ultimately achieving the purpose of successive feeding.

[0027] As Figure 1 , 3 shown, the disk type material discharging bin is connected to the rear end of the belt support through a connecting device. The disk type material discharging bin includes an installation fixing seat, a rotating disk, a material discharging motor, and a grasping induction unit. One side of the installation fixing seat is connected to the rear end of the belt support through a connecting device. The material discharging motor is arranged on the upper side of the installation fixing seat. The rotating disk is arranged at the bottom of the installation fixing seat. The rotating disk is connected to the output shaft of the material discharging motor and is driven by the material discharging motor to rotate. The grasping induction unit is installed on the installation fixing seat in a circular matrix manner and extends above the rotating disk. There is a feeding port at a position on the upper surface of the installation fixing seat close to the rear end of the belt support, and a material discharging port is arranged on the lower side of the installation fixing seat.

[0028] Wherein the installation fixing seat is integrally in a disk shape and includes a circular main body part and a lateral baffle vertically connected to the lower side of the periphery of the main body part. The grasping induction unit is installed on the main body part of the installation fixing seat in a circular matrix manner. A protective cover connected to the lateral baffle of the installation fixing seat is arranged on the lower side of the rotating disk. The feeding port is arranged on one side of the main body part, and the material discharging port is arranged on one side of the protective cover. Wherein the grasping induction unit includes a suction cup, a capturing cylinder, and an infrared induction proximity switch. The installation ends of the suction cup, the capturing cylinder, and the infrared induction proximity switch are respectively installed and fixed in the installation fixing seat. The suction cup, the capturing cylinder, and the infrared induction proximity switch respectively extend above the rotating disk. The control ends of the suction cup, the capturing cylinder, and the infrared induction proximity switch are respectively connected to the control system. The vacuum pressure switch of the suction cup (not shown in the figure) is installed in the control circuit of the control system. The control ends of the above motors are also respectively connected to the control system.

[0029] The working principle of the disc-type material feeding bin is as follows: The material package from the feeding conveyor belt falls onto the rotating disc through the feeding port. The rotating disc is driven by its driving motor, i.e., the material feeding motor, to rotate. The material packages that fall on it also rotate accordingly. Each bin evenly distributed in a circular pattern on the installation fixing base senses the material package through the infrared proximity switch, intercepts the material package with the catching cylinder, and sucks the material package with the suction cup. The vacuum pressure switch connected to the suction cup judges whether the material package is sucked. Then, through program control, the material packages are successively adsorbed from the material feeding port. The suction cup at the first bin position of the material feeding port releases the material according to the rhythm. After the suction cup at the first bin position releases, the suction cups at the subsequent bin positions are successively released. Under the program control, the material packages are successively filled forward to prepare for the next material feeding. The logic of the program control is: When the vacuum pressure switch at the first bin position gives that the suction cup is in the release state, the suction cups at the subsequent bin positions are released. The material package falls on the turntable and moves with the turntable to the first bin position and is sensed by the infrared proximity switch at the first bin position. Then, the catching cylinder intercepts the material package, and the first suction cup sucks the material package to prepare for material feeding. When the suction cup at the second bin position is in the release state, the subsequent action logic is the same as that of the first bin position. In this way, all bin positions are in the state of waiting for materials.

[0030] The cooperation logic between the drum material sorting and the disc-type material feeding bin: When all the suction cups at the bin positions of the disc-type material feeding bin are in the adsorption state, the drum material sorting stops feeding. When four bin positions of the disc-type material feeding bin reach the release state, the drum material sorting starts feeding again. The feeding capacity of the drum material sorting is much greater than the material feeding volume of the disc-type material feeding bin. The drum material sorting is frequently in the standby state, and the material feeding of the disc-type material feeding bin is controlled by the start and stop of the packaging on the packaging line.

[0031] The above embodiments are only the preferred embodiments of the present invention. The present invention is not limited to the forms listed in the above embodiments. The present invention can also be used for other foods with material packages such as instant noodles. Any modifications, equivalent replacements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
