[0051] Example 3

The connecting flange plate 41 is connected to the tail of the launcher, and the connecting flange plate 41 is provided with a loading port 411 that can match the launcher. The pushing mechanism 1, the electric cylinder 3, and the loading bin 2 are assembled and follow the adjustment bracket 42. The electric cylinder 3 and the loading bin 2 are arranged side by side. The electric cylinder 3 is composed of a planetary roller cylinder transmission. The pushing mechanism 1 matches the loading channel 21 on the loading bin 2 for carrying the filling.

The open end of the assembly section 121 matches the supplementary end 212 of the filling channel 21. The one-way chain component 11 can extend out from the open end and extend into the filling channel 21 to push the filler. The storage section 123 of the guide rail 12 is parallel to and matches the filling channel 21; the filler located in the filling channel 21 can be moved to the filling port 411 of the connecting flange plate 41 under the action of the one-way chain component 11, and the filler located at the filling port 411 can enter the launcher and be launched under the action of the electric cylinder 3.

[0053] The loading bin 2 is a cylindrical structure, and ten loading channels 21 are evenly distributed along the circumferential direction of the loading bin 2; the loading bin 2 can be rotatably connected to the adjustment bracket 42, and the pushing mechanism 1 is arranged at the tail end of the loading bin 2 through the adjustment bracket 42. The rotation of the loading bin 2 can make the supplementary end 212 of the designated loading channel 21 match the open end of the assembly section 121 of the guide rail 12.

[0054] Preferably, there are two loading bins 2, namely a first loading bin 22 and a second loading bin 23. The first loading bin 22 and the second loading bin 23 are arranged side by side, and the electric cylinder 3 is arranged between the first loading bin 22 and the second loading bin 23. The two pushing mechanisms 1 correspond to the first loading bin 22 and the second loading bin 23 respectively, and the pushing mechanism 1 is matched with the side of the loading bin 2 close to the electric cylinder 3. The height of the loading port 411 matches the axis height of the loading bin 2. A loading position corresponding to the loading port 411 is provided on the loading bin 2. The loading position is arranged on the opposite side of the loading bin 2 and the other loading bin 2, and the height of the loading position is flush with the axis height of the loading bin 2. The loading channel 21 rotated to the loading position can be moved to align with the loading port 411 by adjusting the bracket 42.

[0055] Specifically, when the filling bin 2 needs to be switched, the distance that the adjustment bracket 42 needs to move is the shortest, thereby ensuring the rapid supply of the filling material.

[0056] When the first loading bin 22 needs to launch the filling, the first loading bin 22 rotates so that the selected filling channel 21 matches the corresponding pushing mechanism 1, and the adjusting bracket 42 moves relative to the connecting flange plate 41 so that the filling end 211 of the filling channel 21 selected in the first loading bin 22 corresponds to the filling port 411 on the connecting flange plate 41. At this time, the one-way chain driving unit 13 of the pushing mechanism 1 is started, driving the one-way chain assembly 11 to extend from the supplementary end 212 of the filling channel 21. The one-way chain assembly 11 remains in a straight state under the action of the elastic member 113 to act on the filling, so that The filler moves from the filling end 211 of the filling channel 21 to the filling port 411 connected to the flange plate 41. The filling port 411 is provided with an elastic stop device 412. When the filler passes through the filling port 411, under the action of thrust, the elastic stopper of the elastic stop device 412 matches with the head end of the filler, so that the elastic stopper of the elastic stop device 412 is compressed and yielded downward. After the filler passes through the filling port 411, the elastic stopper of the elastic stop device 412 re-extends under the action of the spring and limits the tail end of the filler, so as to prevent the filler from retreating during the pitch adjustment process of the cradle 4. After the filler is moved into place, the one-way chain assembly 11 retreats into the guide rail 12 under the action of the one-way chain driving unit 13, and the adjustment bracket 42 moves relative to the connecting flange plate 41, so that the electric cylinder 3 is aligned with the filling port 411, and the push rod 31 of the electric cylinder 3 extends and acts on the filler at the filling port 411, and quickly pushes the filler into the launcher for launch. After the launch is completed, the push rod 31 of the electric cylinder 3 retreats. When the first loading bin 22 launches the filler, the second loading bin 23 rotates so that the selected loading channel 21 matches the corresponding pushing mechanism 1, and the push rod 31 of the electric cylinder 3 After the retraction is completed, the adjustment bracket 42 moves relative to the connecting flange plate 41, so that the loading end 211 of the loading channel 21 selected in the second loading bin 23 corresponds to the loading port 411 on the connecting flange plate 41, and the remaining process is consistent with the process of launching the filler from the first loading bin 22, and will not be repeated here. In this way, the first loading bin 22 and the second loading bin 23 can provide fillers alternately. More preferably, while one loading bin 2 is launching the filler, the other loading bin 2 can simultaneously perform the filler selection operation, which effectively shortens the cycle time of the filler launch. The above-mentioned loading launching process is divided into two stages. In the first stage, the pushing mechanism 1 provides a moving thrust, so that the loading moves from the supplementary end 212 of the loading channel 21 to the loading port 411 connected to the flange plate 41. In the second stage, the electric cylinder 3 provides a launching thrust, so that the loading moves quickly into the launcher and is squeezed and launched. The launching thrust here is much greater than the moving thrust. Through the staged loading launching, the equipment volume can be effectively reduced, the pitch moment of the launching device is balanced, and the power of the whole machine is reduced.

[0057] In order to meet the selection needs of multiple types of fillers, the types of fillers are set to A, B, and C, and the selection scheme of fillers is planned: the ten filling channels 21 of the first filling bin 22 are preset to be loaded with fillers in the order of ABAB..., and the ten filling channels 21 of the second filling bin 23 are preset to be loaded with fillers in the order of ACAC... When selecting fillers, the current filling position is compared with the target filling position to ensure that the filling selection action is completed within the time of rotating two filling channels 21 at most. For example, if the current filling position is type A filler and type A filler needs to be launched, then there is no need to complete the filling selection action and type A filler can be launched directly. If type B filler or type C filler needs to be launched, one filling channel 21 can be rotated. If type A filler continues to be launched, two filling channels 21 are rotated, that is, the maximum rotation angle is 72°.

[0058] Since the filling material is required to enter the launcher in the same direction, the first loading bin 22 and the loading channel 21 on the first loading bin 22 have different structures. The radially outward side of the loading channel 21 of the first loading bin 22 is the radially inward side of the loading channel 21 of the second loading bin 23, and the radially inward side of the loading channel 21 of the first loading bin 22 is the radially outward side of the loading channel 21 of the second loading bin 23.

[0059] The adjusting bracket 42 moves relative to the connecting flange plate 41 through the adjusting driving assembly 43, and the adjusting driving assembly 43 includes a slide rail 431, a slider 432, a gear 433, a rack 434, an adjusting driving motor 435 and an adjusting reduction motor 436. The paired slide rails 431 are respectively arranged at the top and bottom of the corresponding sides of the connecting flange plate 41 and the adjusting bracket 42, and the corresponding sides of the connecting flange plate 41 and the adjusting bracket 42 are also provided with a rack 434. The slide rail 431 is parallel to the rack 434, and the adjusting bracket 42 is provided with a plurality of gears matching the slide rail 431. Slider 432, in this embodiment, each slide rail 431 corresponds to two sliders 432, and the adjusting bracket 42 is also equipped with an adjusting drive motor 435, and the adjusting drive motor 435 is connected to the gear 433 through the adjusting reduction motor 436, and the gear 433 is meshed with the rack 434. After the adjusting drive motor 435 is started, it drives the gear 433 to rotate, so that the gear 433 moves along the rack 434, and then drives the adjusting bracket 42 to move with the gear 433, and at the same time, it also drives the slider 432 on the adjusting bracket 42 to slide along the slide rail 431. Since the equipment has a large deadweight, the reliability of relying solely on two slide rails 431 to bear its own weight and the generated rolling torque is low. Therefore, a sliding support device 5 is installed below the displacement area of ​​the adjusting bracket 42, and a plurality of universal balls 51 are installed in an array at the corresponding positions of the adjusting bracket 42. Both ends of the sliding support device 5 are connected to the cradle 4. The sliding support device 5 provides an upward supporting force for the adjusting bracket 42 to reduce the rolling torque of the slide rail 431. The adjusting bracket 42 can slide on the universal ball 51 along the moving direction, with high reliability, small friction resistance, and low driving energy consumption.
