[0043] The present invention will be further described below with reference to the accompanying drawings:

[0044] The can discharging device mainly consists of a frame assembly 1, a can sorting assembly 2, a can dialing assembly 3 and a can discharging assembly 4.

[0045] See Figure 1 , the frame assembly is composed of a main column 11, a main column 14, a cross beam 13, a connecting beam 12, a mounting plate 15 and a guard rail 16. The cross beam 13 and the connecting beam 12 are connected to the main column 11, the mounting plate 15 is installed on the main column 14, and the guard rail 16 is hoisted under the mounting plate 15 to form a whole firm and reliable frame structure.

[0046] See Figure 3 , the can sorting assembly is composed of a star wheel 21, a star frame 22, a main shaft 23, a sleeve 24, a bearing seat 25, a connecting cover 26, a cover 27, an electromagnet 28 and a transmission device. The transmission device is composed of a motor bracket 29, a reduction box connecting sleeve 1 210, a reduction box connecting sleeve 2 211, a connecting shaft 212, a connecting cover 213, a fork head 214, a converter 215, a sensor 216 and a reduction box 1 217, a reduction box 2 218.

[0047] As Figure 7 , Figure 8 , the star wheel 21 is installed on the star frame 22, the electromagnet 28 is installed in the star frame 22 and connected to the converter 215. The function of the converter 215 is to lead out the wire leading to the electromagnet to avoid wire winding; the main function of the star wheel 21 is to rotate the outlet cans by a certain arranged angle.

[0048] The star frame 22 is installed on the main shaft 23, the sleeve 24 is installed on the mounting plate 15, the main shaft 23 is connected to the bearing seat 25, bearings are installed in the bearing seat 25, the connecting cover 26 is connected to the bearing seat 25 and the reduction box 1 217, and the reduction box 2 218 is installed on the motor bracket 29 (see Figure 10), 5 reduction boxes 1 217 are connected with reduction box 2 218 through reduction box connecting sleeve 1 210 and reduction box connecting sleeve 211, and connecting shaft 212, fork head 214 and sensor 216 are installed on one of reduction boxes 1 217, and each reduction box 1 217 is equipped with a converter 215;

[0049] See Figure 9 The fork head 214 is mounted on the main shaft 23, and the fork head 214 and the connecting cover 213 rotate or stop together with the main shaft 23 when they are engaged or disengaged; the sensor 216 is above the fork head 214 in the reduction box 217.

[0050] Sensor 216 may be a PR12-4DN2 sensor.

[0051] When the reduction box 218 receives the signal and rotates, it drives the five reduction boxes 1 217 to rotate, and drives the main shaft 23 and the star frame 22 to rotate. The electromagnet 28 is energized to attract the can body and rotate it 120 degrees into place. The next can is also fed into place. At the same time, the fork head 214 sends a signal to the sensor 216, and the reduction box 218 stops rotating, completing a working cycle, and this is repeated.

[0052] 3. The pot-pushing assembly is composed of a lever 31, a lever seat 32, a lever frame 33, a slide bar 34, a slide seat 35, a pull rod 36, a cylinder 37, a cover 38 and a pot-pushing device.

[0053] The can push device is composed of a fixing plate 1 39, a fixing plate 2 310, a fixing support 311, a push bar 312 and a cylinder 2 313. Figure 11 The lever 31 is mounted on the lever seat 32, the lever seat 32 is mounted on the frame 33, the frame 33 is mounted on the slide seat 35, the slide seat 35 is mounted on the slide rod 34 and connected to the frame 33, and is pulled by the cylinder 37 to move telescopically.

[0054] The fixing plate 1 39 and the fixing plate 2 310 are fixed on the frame, and the fixing support 311 is connected with the cylinder 2 313 and the push gear 312. The cylinder 2 313 is telescopic to push the tank body to move.

[0055] See Figure 4 and Figure 11 The slide seat 35 is mounted on the slide rod 34 and connected to the pull frame 33, and is pulled and telescopically moved by the cylinder; both ends of the slide rod 34 are fixed on the mounting plate 15 through the slide rod seat 30.

[0056] See also Figure 5 , Figure 13 The tank discharging assembly is composed of an upper support plate, a lower support plate, a sleeve 1 45, a sleeve 2 46, a positioning rod 47 and a magnetic suction device 48. A channel is formed between the two sets of upper and lower support plates. Figure 2, this technical solution has 5 can-arranging channels. One channel is formed between a side baffle and a set of upper and lower backing plates, and the other four channels are formed between two sets of upper and lower backing plates.

[0057] The magnetic attraction device is internally equipped with an electromagnet 28 installed between backing plate one 41, backing plate two 42, backing plate three 43, and backing plate four 44. It is integrally hoisted under the mounting plate 15 through sleeve one 45, sleeve two 46, and positioning rod 47. Sleeve 45 is installed between backing plates 41 and 42 and between 43 and 44. Sleeve 46 is installed between the backing plate and the mounting plate 15, and then there is a positioning rod 47 in the middle of the sleeve to connect and fix them; the electromagnet 28 is energized to magnetically attract the tank body to assist the star frame to guide the tank body through the can-arranging channel.

[0058] See Figure 12 , two magnets on the same side as the star wheel in the channel are installed in an iron box, which forms a magnetic attraction device 48 with the iron box. The iron box is embedded between the upper and lower backing plates. When the electromagnet 28 in the energized iron box becomes magnetic and attracts the tank body, it is energized synchronously when the star wheel starts to rotate. When the star wheel rotates 10 degrees, the magnetic attraction device 48 is powered off. The star wheel is energized to attract the tank body and rotate 180 degrees in place. The next tank in the channel also advances and positions in place. When the star wheel gets a signal to rotate again, the magnetic attraction device 48 is also energized to attract the tank body, and so on in the cyclic working process.

[0059] Electrical description:

[0060] The rotation control signal of the star wheel is the signal detected by the electric eye of the subsequent can-stacking device for the required full-tank quantity, which is sent to the PLC. Then the PLC controls the motor controller, and the motor rotates, driving the reducer to rotate together. When the sensor senses the fork head (the fork head is installed on the main shaft of the star wheel and is connected to the output shaft of the reducer), it sends a signal to the PLC, and the motor stops rotating, and so on in a cycle.

[0061] The control signal for the movement of the lever is also the same signal as the motor. The signal detected by the electric eye of the subsequent can-stacking device for the required full-tank quantity is sent to the PLC. Then the PLC controls the pneumatic cylinder solenoid valve to actuate, supply air to the pneumatic cylinder, the pneumatic cylinder expands and contracts, driving the carriage slider to move along the slide rod, and the lever moves to push the can. The tank body follows the mesh belt into the can-arranging channel.

[0062] The model of the electric eye can be CX-491.

[0063] In addition, it should be noted that, in the case of no contradiction, the various specific technical features described in the above specific embodiments can be combined in any suitable way. To avoid unnecessary repetition, the present invention does not separately describe various possible combination methods.
