Description

Technical Field

[0001] The utility model relates to the technical field of rotary machines, and particularly relates to a rotary filling machine. Background Art

[0002] In order to save labor costs and increase work efficiency, factories generally choose to use automated equipment for work. Some automated equipment is designed as a disc in order to combine different processes for processing on the same equipment. Such equipment generally has multiple workstations and uses a circular turntable to transport materials, thereby saving the space occupied by a single piece of equipment.

[0003] A Chinese utility model patent document with the authorization announcement number of CN220743531U discloses a filling device and a filling machine. The filling device includes a fixing plate; a turntable mechanism, the turntable mechanism includes a rotating shaft and a disc, the rotating shaft is rotatably connected to the fixing plate, the disc is located above the fixing plate, the disc can reciprocate back and forth along the length direction of the rotating shaft and is fixed relative to the rotating shaft through a fixing member, a plurality of station holes are provided on the side of the disc, and a cup supporting jig can be movably installed in the station holes, and the cup supporting jig is used for installing a container; a filling head, the filling head is located above a station hole; and a cup supporting mechanism, the cup supporting mechanism is located below the disc and below the filling head, and the cup supporting mechanism is used for lifting the cup supporting jig. The turntable mechanism further includes a driving member, the driving member can be a motor, and the driving member can also be a gearbox for transmitting power. The driving member is installed at the bottom of the fixing plate, and the output shaft of the driving member can rotatably penetrate the fixing plate and is fixedly connected to the rotating shaft, so as to facilitate the driving member to drive the rotating shaft to rotate, thereby realizing driving the disc to rotate.

[0062] A number of placement seats 111 are provided at a position on the upper end of the disc 110 close to the outer peripheral wall of the disc 110. The number of placement seats 111 is arranged in an annular equidistant manner with the axis of the disc 110 as the center. Each placement seat 111 includes a relatively arranged first seat body and a second seat body. In this embodiment, the disc 110 adopts a 24-station indexing disc, and 24 placement seats 111 are provided at a position on the upper end of the disc 110 close to the outer peripheral wall of the disc 110. That is to say, the included angle between the ray from the center point of the disc 110 to one of the placement seats 111 and the ray from the center point of the disc 110 to the placement seat 111 adjacent to it in the clockwise or counterclockwise direction is 15°. The blowing and sucking device 120, the filling device 130, the inner plugging device 140, the capping device 150, and the bottle picking and placing device 160 are sequentially installed on the upper end of the table board 100 in the clockwise direction around the disc 110.

[0063] Wherein, the included angle between the ray from the center point of the disc 110 pointing to the blowing and suction device 120 and the ray from the center point of the disc 110 pointing to the filling device 130 is equal to 30°; the included angle between the ray from the center point of the disc 110 pointing to the filling device 130 and the ray from the center point of the disc 110 pointing to the inner plugging device 140 is equal to 60°; the included angle between the ray from the center point of the disc 110 pointing to the inner plugging device 140 and the ray from the center point of the disc 110 pointing to the capping device 150 is equal to 105°; the included angle between the ray from the center point of the disc 110 pointing to the capping device 150 and the ray from the center point of the disc 110 pointing to the bottle picking and placing device 160 is equal to 45°.

[0064] It should be noted that the airtightness detection device 300, the blowing and suction device 120, the filling device 130, the inner plugging device 140, the capping device 150 and the bottle picking and placing device 160 are all existing conventional devices purchased on the market.

[0065] During filling, it is necessary to prepare filling materials, filling bottles, inner plugs, inspection caps and bottle caps. Before filling, it is necessary to first remove dust and clean the filling bottles, then fill the filling materials into the filling bottles, then press on the inner plugs, and finally screw on the inspection caps. After the inspection caps are screwed on, they are transported to the airtightness detection device 300 for detection. After passing the detection, the inspection caps are removed and the bottle caps are screwed on to complete all filling tasks.

[0066] In this embodiment, in order to facilitate the detection of filling quality, the inspection caps are inspection caps matching the airtightness detection device 300. It should be noted that the inspection caps are existing conventional inspection caps that can be purchased on the market.

[0067] A positioning cylinder 400 is installed around the upper end of the table board 100 and around the disc 110. An induction device for detecting whether a positioning groove 112 mentioned below is opposite to the position of the piston rod of the positioning cylinder 400 is installed on the positioning cylinder 400. When the induction device detects that there is a positioning groove 112 opposite to the position of the piston rod of the positioning cylinder 400, the piston rod of the positioning cylinder 400 extends. It should be noted that the induction device is a conventional induction device that can be directly purchased on the market. The piston rod of the positioning cylinder 400 is horizontally arranged and faces the disc 110; the piston rod of the positioning cylinder 400 is fixedly connected with a brake head 410; one end of the brake head 410 is fixedly connected to the piston rod of the positioning cylinder 400, and the other end is provided with a first sliding hole, and the first sliding hole is a blind hole with an opening facing the disc 110; a bullet head 420 is slidably connected in the first sliding hole. In this embodiment, the bullet head 420 includes a bullet head body 420a and a limiting rod 420b. One end of the bullet head body 420a is close to the bottom of the first sliding hole, and the other end is far from the bottom of the first sliding hole; a limiting groove penetrating the brake head 410 is provided on the hole wall of the first sliding hole, and one end of the limiting rod 420b is screwed on the side wall of the bullet head body 420a, and the other end is slidably connected to the limiting groove. By providing a limiting groove penetrating the brake head 410 and screwing the limiting rod 420b on the bullet head body 420a, it is convenient for disassembly and installation when the bullet head body 420a needs to be repaired and replaced.

[0068] A spring 430 is arranged between the bottom of the first sliding hole and the bullet head 420; the spring 430 is a compression spring, and the spring 430 is coaxially arranged with the first sliding hole. One end of the spring 430 abuts against the bottom of the first sliding hole, and the other end abuts against the bullet head 420. Specifically, the spring 430 abuts against one end of the bullet head body 420a close to the bottom of the first sliding hole; a roller 421 is rotatably connected to the end of the bullet head 420 far from the bottom of the first sliding hole. Specifically, a roller 421 is rotatably connected to the end of the bullet head body 420a far from the bottom of the first sliding hole, and the axis of the roller 421 is vertically arranged. By providing the roller 421, when the brake head 410 contacts the outer peripheral side wall of the disc 110, it is beneficial to reduce or even eliminate the tangential action of the disc 110 on the brake head 41.

[0069] A plurality of positioning grooves 112 are formed in the outer peripheral side wall of the disc 110. The plurality of positioning grooves 112 and the positioning cylinder 400 are in the same plane. In this embodiment, 24 positioning grooves 112 are formed in the outer peripheral side wall of the disc 110. The 24 positioning grooves 112 are arranged in an annular and equidistant manner centered on the axis of the disc 110. The 24 positioning grooves 112 and the piston rod of the positioning cylinder 400 are in the same plane. And when the piston rod of the positioning cylinder 400 is inserted into one of the positioning grooves 112, one of the placement seats 111 is exactly on the ray pointing from the center point of the disc 110 to the blowing and suction device 120; the second placement seat 111 in the clockwise direction of the placement seat 111 on the ray pointing from the center point of the disc 110 to the blowing and suction device 120 is exactly on the ray pointing from the center point of the disc 110 to the filling device 130; the fourth placement seat 111 in the clockwise direction of the placement seat 111 on the ray pointing from the center point of the disc 110 to the filling device 130 is exactly on the ray pointing from the center point of the disc 110 to the inner plugging device 140; the seventh placement seat 111 in the clockwise direction of the placement seat 111 on the ray pointing from the center point of the disc 110 to the inner plugging device 140 is exactly on the ray pointing from the center point of the disc 110 to the capping device 150; the third placement seat 111 in the clockwise direction of the placement seat 111 on the ray pointing from the center point of the disc 110 to the capping device 150 is exactly on the ray pointing from the center point of the disc 110 to the bottle picking and placing device 160.

[0070] The placement seat 111 on the ray pointing from the center point of the disc 110 to the blowing and suction device 120 is within the working range of the blowing and suction device 120; the placement seat 111 on the ray pointing from the center point of the disc 110 to the filling device 130 is within the working range of the filling device 130; the placement seat 111 on the ray pointing from the center point of the disc 110 to the inner plugging device 140 is within the working range of the inner plugging device 140; the placement seat 111 on the ray pointing from the center point of the disc 110 to the capping device 150 is within the working range of the capping device 150; the placement seat 111 on the ray pointing from the center point of the disc 110 to the bottle picking and placing device 160 is within the working range of the bottle picking and placing device 160.

[0071] Taking the position after the piston rod of the positioning cylinder 400 contracts as the initial position. When the piston rod of the positioning cylinder 400 is in the initial position, the distance between the axis of the roller 421 and the axis of the disc 110 is greater than the sum of the radius of the roller 421 and the radius of the disc 110. Refer to Figure 5 , when the piston rod of the positioning cylinder 400 is in the initial position and the positioning groove 112 rotates to a position opposite to the piston rod of the positioning cylinder 400, the roller 421 is outside the positioning groove 112; Refer to Figure 6, when the piston rod of the positioning cylinder 400 is in the initial position and the positioning groove 112 rotates to a position not corresponding to the position of the piston rod of the positioning cylinder 400, there is a gap between the roller 421 and the outer peripheral side wall of the disc 110.

[0072] Furthermore, guide blocks 115 fixed to the upper end of the table board 100 are respectively arranged on both sides of the piston rod of the positioning cylinder 400. By arranging the guide blocks 115, during the process of the piston rod of the positioning cylinder 400 being inserted into the positioning groove 112, it is beneficial to prevent the rotational kinetic energy of the disc 110 from impacting the piston rod of the positioning cylinder 400, resulting in the bending of the piston rod of the positioning cylinder 400 or the deviation of the axis of the piston rod.

[0073] Furthermore, a second sliding hole is also provided at one end of the piston rod of the positioning cylinder 400 where the brake head 410 is fixed.

The screw rod of the bolt 440 passes through the communication hole and is screwed with the bullet head 420. Specifically, an internal thread hole is provided at one end of the bullet head body 420a close to the bottom of the first sliding hole. The screw rod of the bolt 440 passes through the communication hole and is screwed with the internal thread hole. By rotating the bolt 440, the length of the screw rod of the bolt 440 in the internal thread hole is adjusted, and thus the maximum distance from the end of the bullet head 420 away from the bottom of the first sliding hole to the bottom of the first sliding hole is adjusted.

[0074] Furthermore, a bottle placing station 170, a plugging station 180, and a capping station 190 are sequentially arranged around the disc 110 in the clockwise direction on the upper end of the table board 100; the bottle placing station 170 is located between the blowing and sucking device 120 and the bottle picking and placing device 160, the plugging station 180 is located between the filling device 130 and the inner plugging device 140, and the capping station 190 is located between the inner plugging device 140 and the capping device 150.

By setting the capping station 190, it is used for manual or a capping inspection robot to place the inspection caps on the bottle mouths of the corresponding filled bottles.

[0079] By setting the bottle placing robot, the inner plugging robot and the capping inspection robot, it is beneficial to improve the automation production efficiency. It should be noted that the bottle placing robot, the inner plugging robot and the capping inspection robot are conventional robots purchased on the market.

[0080] One end of the conveying device 200 is fixedly connected to the table board, and the conveying path of the conveying device 200 sequentially passes through the working range of the bottle picking and placing device 160 and the working range of the airtightness detection device 300.

By providing the first detection table, it is used to screen the filling bottles that obviously do not meet the filling quality. Among them, the situation that obviously does not meet the filling quality refers to the product defects that can be found by the human eye, such as the filling material visibly oozing out of the filling bottle or the detection cover of the filling bottle not being installed. It should be noted that the first detection table can be an existing conventional visual detection platform or automatic optical detection platform purchased on the market, or the first detection table can also be a detection station platform, and screening is carried out manually at the detection station. After screening, the filling bottles that are not found to obviously not meet the filling quality are transferred to the second conveying device 220, and the filling bottles that obviously do not meet the filling quality are directly removed and refilled.

[0082] Further, a bottle transferring manipulator (not shown in the figure) is installed on one side of the discharging end of the first conveying device 210.

[0096] After the piston rod of the positioning cylinder 400 extends and retracts once again, the motor drives the disc 110 to rotate clockwise. When the piston rod of the positioning cylinder 400 is opposite the next positioning groove 112, the piston rod of the positioning cylinder 400 extends, the motor stops providing power, and the filling bottle reaches the working range of the inner plugging station 180. The inner plug is placed on the mouth of the filling bottle manually or by the inner plugging manipulator at the inner plugging station 180.

[0098] After the piston rod of the positioning cylinder 400 extends and retracts three more times, the motor drives the disc 110 to rotate clockwise. When the piston rod of the positioning cylinder 400 is opposite to the next positioning groove 112, the piston rod of the positioning cylinder 400 extends, and the motor stops providing power. The filling bottle reaches the working range of the upper cover station 190, and a detection cover is placed on the bottle mouth of the filling bottle by manual labor or the upper detection cover manipulator on the upper cover station 190.

When the piston rod of the positioning cylinder 400 is opposite to the next positioning groove 112, the piston rod of the positioning cylinder 400 extends, and the motor stops providing power. The filling bottle reaches the working range of the capping device 150, and the capping device 150 screws the detection cover tightly. After the capping operation is completed, the piston rod of the positioning cylinder 400 retracts, and the motor continues to drive the disc 110 to rotate clockwise.

When the piston rod of the positioning cylinder 400 is opposite to the next positioning groove 112, the piston rod of the positioning cylinder 400 extends, and the motor stops providing power. The filling bottle reaches the working range of the bottle picking and placing device 160, and the bottle picking and placing device 160 lifts the filling bottle from the placing seat 111 and places it on the first conveying device 210. The first conveying device 210 operates, and the filling bottle is conveyed to the discharge end of the first conveying device 210, and the filling bottle is screened by a vision inspection platform or an automatic optical inspection platform.

[0101] After screening, when it is not found that the filling bottle is significantly inconsistent with the filling quality, the bottle transferring manipulator transfers the filling bottle to the second conveying device 220. When it is found that the filling bottle is significantly inconsistent with the filling quality, the bottle transferring manipulator directly rejects the filling bottle and refills it.

[0102] If the bottle transferring manipulator transfers the filling bottle to the second conveying device 220, the filling bottle is conveyed to the position corresponding to the airtightness detection device 300, and the airtightness detection device 300 performs an airtightness detection on the filling bottle. After the detection is qualified, the detection cover is removed and the bottle cap is screwed on to complete all filling tasks.

[0103] By arranging the positioning cylinder 400 at the lower end of the table board 100 and providing the positioning grooves 112 on the outer peripheral side wall of the disc 110, when the motor drives the disc 110 to rotate until the positioning groove 112 is opposite to the position of the positioning cylinder 400, the piston rod of the positioning cylinder 400 extends, and the motor stops providing power. The control of the stop position of the disc is relatively good, which is beneficial to improving the filling quality.
