[0020] As shown in Figures 1-3 The automatic tank unloading device comprises, from front to back, a disc unloading operation platform 1, a falling tank operation platform, and a disc stacking operation platform 3. The falling tank operation platform is provided with a first conveying line 2 and a falling tank support frame 5. The falling tank support frame 5 is provided with a front-rear connected pushing tank cylinder 6 and a slide way 8. The side surface of the pushing tank cylinder 6 is connected with a second conveying line 4 for conveying tea cans through a metronome 7. The first conveying line 2 is installed on the rack of the falling tank operation platform, can convey the blister tray of the disc unloading operation platform 1 to the lower side of the slide way 8, and send the blister tray 10 to the disc stacking operation platform 3 after loading the tea cans.
[0021] The unloading operation table 1 is used to place the blister tray 10 delivered by the automatic pallet unloading equipment. A pushing cylinder (not shown in the figure) is provided on the side away from the can dropping operation table. When the pushing cylinder senses that the blister tray falls onto the unloading operation table 1, the pushing cylinder starts to work and pushes the blister tray 10 onto the first conveyor line 2 of the can dropping operation table.
[0022] The first conveyor line 2 includes rollers installed on the front and rear sides of the can drop operation table, and a conveyor belt installed on the two rollers. One of the rollers is connected to a rotating motor. The rotating motor adopts a stepping motor, which can achieve precise control of the moving distance of the first conveyor line 2 by setting pulses.
[0023] The can drop support frame 5 is located above the first conveyor line 2, and the space below the can drop support frame 5 can pass through the blister tray 10. A limiting device is provided on the can drop support frame 5 and / or the can drop operating table. The limiting device can adopt a guide rod to limit the moving direction of the blister tray 10. When the blister tray 10 reaches the exit of the slide 8, as the blister tray moves forward, the grooves of each row of the blister tray can be loaded with tea cans in turn.
[0024] For example, when the can drop support frame 5 is provided with a limit device, the front can push cylinder 6 is provided with legs on both sides, namely the left leg and the right leg. The bottom of the legs is fixedly connected to the frame of the can drop operation table by bolts. The legs on both sides cross the first conveyor line 2, and the middle is used to pass the blister tray. In this way, when the first conveyor line 2 is working, it can carry the blister tray through the middle of the two legs. In order to limit the forward direction of the blister tray, a guide rod is provided on the inner side of the legs, such as Figure 4 As shown, both left legs 11 are provided with a left guide rod 12, and both right legs 13 are provided with a right guide rod 14. The left guide rod 12 and the right guide rod 14 have the same structure and are arranged opposite to each other, with their ends facing the stacking operating table 3 at the rear.
[0025] When the blister tray reaches the bottom of the can pushing cylinder 6, its forward direction can be adjusted by the guide rod. Furthermore, the two sides of the slide 8 are also provided with legs 15 that cross the first conveyor line 2, and guide rods 16 can also be provided on the legs. When the front end of the blister tray reaches the bottom of the slide 8, the rear end is affected by the guide rod of the can pushing cylinder 6, so that the blister tray is parallel to the direction of travel of the first conveyor line 2, and the grooves of one row of the blister tray can face the slide 8. The slide 8 is provided with a plurality of parallel sliding positions, each sliding position corresponding to a groove. When the blister tray is provided with n grooves in each row, the slide 8 is provided with n parallel sliding positions, and n is a natural number, ranging from 6 to 12. Furthermore, a partition is provided between adjacent sliding positions to prevent the tea can from entering another sliding position from one sliding position.
[0026] Similarly, the frame of the can falling operation platform can also be provided with a limiting device on both sides, which can adopt a guide rod or other limiting device such as a width-narrowing limiting guide strip to limit the position of both sides of the blister tray, so that the blister tray can face the outlet of the slide 8 when advancing, and each row of grooves of the blister tray can face the sliding position of the slide 8.
[0027] The second conveying line 4 is used for conveying tea cans, and a metronome 7 is arranged between the second conveying line 4 and the can falling support frame 5 at the end of the second conveying line 4. The tea cans are arranged in a row at the push plate of the can pushing cylinder 6 through the metronome 7, each tea can corresponds to a sliding position of the slide 8, and the outlet of each sliding position faces a row of grooves arranged on the blister tray. The tea cans can also be counted through the metronome 7. When the tea cans are arranged in a row and meet the number of each row of grooves of the blister tray, the can pushing cylinder 6 works, and the push plate arranged therein pushes the tea cans into the sliding position and then into each row of grooves. When the grooves of the previous row are filled with tea cans, the second conveying line 4 continues to run, so that the grooves of the next row correspond to the sliding position, until all the grooves are loaded, and the second conveying line 4 continues to run to send the current blister tray to the tray stacking operation platform 3 and convey the next empty blister tray to the position below the slide 8.
[0028] Further, the can falling operation platform is provided with a proximity switch at the frame below the outlet of the slide 8, which is used to sense whether the blister tray is in place. In use, the blister tray is sent to the position below the slide through the first conveying line 2 and stops running when reaching the proximity switch, at this time, the grooves of the first row of the blister tray face the outlet of the slide, the tea cans reach the can pushing cylinder 6 through the second conveying line 4 and the metronome 7, and when a row is full, the can pushing cylinder 6 pushes the tea cans to the slide, and the tea cans fall into the blister tray through the slide. The rotation motor is driven to make the grooves of the second row of the blister tray face the outlet of the slide, and the can filling operation is repeated until a blister tray is filled, and then the blister tray reaches the tray stacking operation platform 3 through the first conveying line 2. The tray stacking operation platform 3 can scan the blister tray through photoelectric scanning to check whether the blister tray is without a can or exceeds the limit, and then the cylinder below the blister tray is lifted to lift the blister tray to the loading position.
[0029] The working process of the utility model is as follows:
[0030] Step S1: The blister tray falls to the tray unloading operation platform 1 through the automatic tray unloading device, and then is pushed to the first conveying line 2 through the tray pushing cylinder, and reaches the first position below the outlet of the slide through the first conveying line 2, wherein the first position is provided with a position sensor, and the position sensor adopts a proximity switch.
[0031] When the tea can reaches the rhytmic device 7 through the second conveying line 4, the rhytmic device 7 is sequentially operated to make the tea cans be spaced, and the rhytmic device 7 is stopped after the counter satisfies the counting, and the synchronous pushing cylinder is operated to push the tea cans to the upper end of the slide, and then the pushing cylinder is returned, and the tea cans are automatically put into the blister tray through the slide; the blister tray is provided with 9 rows of grooves;
[0032] S2: when the tea can is completely put into the first row of grooves of the blister tray, the first conveying line is rotated through the fixed pulse value of the stepping motor to make the blister tray reach the next row of grooves, and the next group of tea cans is waited.
[0033] Further, when the pushing cylinder is returned to trigger the magnetic photoelectric signal after the step S1, the rhytmic device 7 is sequentially operated when the magnetic photoelectric signal is detected, the step S1 is repeated, and the 9th group is sequentially circulated; the first conveying line is continuously operated until the next group of blister trays reaches the first position, and the reciprocating circulation is realized.
[0034] In the step S2, the blister tray is moved according to the movement pulse setting value of the rear blister tray, and after the blister tray completely reaches the stacking operation table 3, the lifting cylinder is operated to lift the blister tray to the boxing position after the photoelectric scanning is not turned over and the abnormality is not exceeded, and the reciprocating operation is realized.
[0035] In the utility model, the tea can reaches the rhytmic device through the conveying line, the sequential operation of the rhytmic device can accurately count the counter, and the counter is pushed into the slide through the cylinder after the counting is satisfied, and the tea can is accurately put into the blister tray through the slide, and the manual picking and storage are not needed, and the equipment replaces the manual operation.
