It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below for illustration. Example

[0024] See also Figure 1The present invention provides an automatic discharging device for placing a single dried fruit on food, which includes a frame 1. The upper part of the frame 1 is provided with a vibration plate 2, a differential feeding device 3, a stepping material sorting device 4, a material picking and discharging device 5 and a tray conveying device 6. The material picking and discharging device 5 is arranged above the tray conveying device 6. The vibration plate 2, the differential feeding device 3, the stepping material sorting device 4, the material picking and discharging device 5 are arranged in sequence along the production conveying direction. A control box 7 is arranged in the frame 1. A controller is arranged in the control box 7. The controller is electrically connected to the vibration plate 2, the differential feeding device 3, the stepping material sorting device 4, the material picking and discharging device 5 and the tray conveying device 6 respectively.

[0025] Working principle: Turn on the equipment, manually pour a certain amount of dried fruit into the vibration plate 2, the vibration plate 2 arranges the dried fruit in single pieces and sends them to the differential feeding device 3, then the differential feeding device 3 realizes the complete separation of the dried fruit through two sections of unequal speed conveyor belts and drops them into the stepping material sorting device 4, the stepping material sorting device 4 positions and arranges the single dried fruit through a number of equidistantly arranged fixture blocks 43 and transports them by stepping movement, and finally the material picking and discharging device 5 grabs a number of dried fruit from a number of fixture blocks 43 and places them on the food transported by the tray conveying device 6, thereby realizing the automatic placement of a single dried fruit on the food.

[0026] Specifically, Figure 2 As shown, the differential feeding device 3 includes a low-speed conveyor belt 31 and a high-speed conveyor belt 32 connected to each other. The input end of the low-speed conveyor belt 31 corresponds to the discharge port of the vibration plate 2, and the output end of the low-speed conveyor belt 31 is connected to the input end of the high-speed conveyor belt 32 in an upper and lower manner. The output end of the high-speed conveyor belt 32 is located above the stepping material sorting device 4. The input end of the low-speed conveyor belt 31 is provided with a first sensor 33, and the first sensor 33 is connected to a first air nozzle 34. The first sensor 33 can be a photoelectric sensor, which is used to identify dried fruits. When it is identified that there are dried fruits that are close together, the first air nozzle 34 blows air to blow the dried fruits that are close together after the single dried fruit back into the vibration plate 2, ensuring that the dried fruits conveyed by the vibration plate 2 are intermittent, and realizing the preliminary separation of the dried fruits. Then, the dried fruits are conveyed through the low-speed conveyor belt 31 and the high-speed conveyor belt 32 in sequence. At the intersection of the two conveyor belts, the distance between two adjacent dried fruits is further increased to achieve complete separation of the dried fruits, so that the dried fruits can be conveyed in single pieces, and a certain distance is maintained between two adjacent dried fruits.

[0027] Furthermore, a second sensor 35 is provided at the output end of the high-speed conveyor belt 32, and the second sensor 35 is electrically connected to the controller. The second sensor 35 can be a photoelectric sensor.

[0028] Specifically, Figure 3As shown, the stepping material sorting device 4 includes a chain conveyor 41, a stepping motor 42 and a plurality of jig blocks 43. The plurality of jig blocks 43 are arranged equidistantly on the chain conveyor 41. Each jig block 43 is provided with a single dried fruit placement slot. The stepping motor 42 is arranged at one end of the chain conveyor 41 to drive the chain conveyor 41 to operate. The stepping motor 42 is electrically connected to the controller. When the second sensor 35 detects that a single dried fruit falls into the jig block 43 on the stepping material sorting device 4, the second sensor 35 sends a signal to the controller to control the stepping motor 42 to move an equidistant quickly, so that the jig block with the dried fruit is removed and the empty jig block is connected. After multiple similar actions, a certain number of dried fruits are arranged equidistantly on the chain conveyor 41 (each jig block 43 corresponds to one dried fruit).

[0029] In order to make the dried fruits arranged equidistantly present the same shape, in this embodiment, the single-grain dried fruit placement groove is designed with a V-shaped groove, and one side of the single-grain dried fruit placement groove faces the output end of the high-speed conveyor belt 32. A baffle 44 is provided on the other side of the single-grain dried fruit placement groove corresponding to the docking end of the chain conveyor belt 41 and the high-speed conveyor belt 32, and a cylinder 45 is provided at the rear end of the baffle 44. A second air nozzle 46 is provided on one side of the baffle 44 along the movement direction of the chain conveyor belt 41.

[0030] When dried fruits fall onto the single-grain dried fruit placement slot, they usually appear in three forms: 1. Dried fruits leaning against the side wall of the V-shaped groove; 2. Dried fruits leaning against the baffle 44; 3. Dried fruits lying flat on the bottom of the V-shaped groove. For the production process, the third form is the most ideal grasping form. Dried fruits leaning against the baffle 44 can be collided with the baffle 44 by the cylinder 45, so that the dried fruits leaning against the baffle 44 are separated from the baffle 44, and the dried fruits leaning against the side wall of the V-shaped groove can be adjusted in direction by blowing air through the second air nozzle 46, so that they are corrected to the third form. After multiple actions of the cylinder 45 and the second air nozzle 46, a certain number of dried fruits of the same form are evenly arranged on the chain conveyor 41.

[0031] In this embodiment, the low-speed conveyor belt 31, the high-speed conveyor belt 32, and the chain conveyor belt 41 are correspondingly provided in two groups, and the vibration plate 2 has two discharge ports. By providing two groups, the work efficiency can be effectively improved, wherein the two groups of low-speed conveyor belts 31, high-speed conveyor belts 32, and chain conveyor belts 41 are all able to operate synchronously, so that the material taking and discharging device 5 can grab two groups of dried fruits at one time.

[0032] Specifically, the tray conveying device 6 includes a conveying base 61 and a tray 62 . A synchronous conveyor belt 63 is provided in the conveying base 61 . The tray 62 is placed on the synchronous conveyor belt 63 for transportation, and the dried fruit food to be placed on the tray 62 .

[0033] Specifically, Figure 4As shown, the material taking and discharging device 5 includes a gantry bracket 51, a robot arm 52, a lifting device 53, a connecting plate 54, an electric push cylinder 55, a push block 56 and a pin 57. The gantry bracket 51 is arranged above the material tray conveying device 6. One end of the robot arm 52 is arranged on the gantry bracket 51, and the lifting device 53 is arranged at the other end of the robot arm 52. A connecting plate 54 is arranged at the bottom of the lifting device 53. A plurality of electric push cylinders 55 are arranged on the top of the connecting plate 54. A plurality of push blocks 56 corresponding to the plurality of electric push cylinders 55 are arranged at the bottom of the connecting plate 54. The plurality of push blocks 56 are arranged in two rows at equal intervals. The output shaft of the electric push cylinder 55 passes through the connecting plate 54 and is connected to the push block 56. A through hole is provided in the push block 56. A pin 57 is convexly provided at the bottom of each push block 56. The pin 57 is inserted from the through hole and fixed to the connecting plate 54. The robot arm 52 has a rotating joint. When the material taking and discharging device 5 takes the material, the mechanical arm 52 rotates the several pins 57 at the bottom of the connecting plate 54 to the top of the several jig blocks 43 containing dried fruits on the corresponding chain conveyor 41, and then the lifting device 53 descends to insert the several dried fruits on the corresponding pins 57. Then the lifting device 53 and the mechanical arm 52 are reset, and the several pins 57 are located above the material tray 62 after reset. Finally, the electric push cylinder 55 pushes the push block 56 to push the several dried fruits onto the food. In this process, the moving speed of the push block 56 determines the speed at which the dried fruits finally fall. The falling speed of the dried fruits is an important parameter that affects the qualified placement rate. Different types of food and dried fruits require different pushing speeds. Since the cylinder speed is affected by many factors such as air supply pressure, throttle valve, air pipe and cylinder lubrication, it is difficult to obtain and maintain a stable speed. However, the electric push cylinder is different. The electric push cylinder 55 can be driven by a servo motor driving a ball screw. The servo motor has a speed closed-loop control system, which makes it easy to obtain a stable speed and can be set to a variable speed during the pushing process, so that the equipment maintains a high yield.

[0034] The invention realizes the automation of the whole process from the working procedures of dried fruit feeding, single fruit separation, equidistant arrangement, grabbing and placing, etc., achieves the purpose of reducing labor costs and improving production efficiency, and the operation is simple, only needs to manually pour the dried fruits into the vibration plate, and there is no other operation in the production process. The degree of automation is high, and it is suitable for large-scale production.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
