[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Anti-mite spray is a household product used to eliminate mites. To facilitate the use of the product, the bottle cap usually adopts a gun-shaped spray head design, also known as a "duckbill cap" or pump head cap. The gun-shaped spray head includes a cap body that is on the same axis as the bottle body, and a nozzle that is perpendicular to the axis of the bottle body. The nozzle has a protruding structure on the side of the top of the bottle body. The gun-shaped spray head is usually assembled on the bottle body by an automatic turntable machine.

[0031] Currently, the turntable machine mainly includes a turntable body that pushes the bottle body to move, a capping mechanism that screws the gun-shaped spray head onto the bottle body, and a conveying mechanism that moves the screwed-on bottle body from the turntable to the conveyor line. In actual use, the various mechanisms work together to form part of the automatic packaging line for mite-removing spray.

[0032] The existing gun-shaped spray head is connected to the bottle mouth by a screw cap, and the screw cap and spray head can also rotate accordingly, which makes it easy for users to flexibly adjust the direction of the spray head during actual use. Therefore, in actual use, the gun-shaped spray head is packaged by the existing rotary machine. The shortcoming is that after the gun-shaped spray head is screwed on the bottle, some of the spray head nozzles have inconsistent orientations.

[0033] In other words, for example, when the bottle is fixed, the screw cap is in the 12 o'clock position as the final tightened position. Since the nozzles can also rotate relative to the screw cap, it's not certain that every nozzle will be in the 12 o'clock position when the screw cap is in the 12 o'clock position, or that every nozzle will be in the 14 o'clock position. That is, after the screw cap is tightened on the bottle, some nozzles may be in the 6 o'clock position, others in the 3 o'clock position, and so on. It's difficult to ensure that the orientation of each nozzle is consistent after the screw cap is tightened. Although inconsistent nozzle orientation does not affect the normal use of the product, the turntable machine works in conjunction with the entire automated packaging production line, and maintaining consistency along the production line is a key factor for normal operation. Therefore, inconsistent nozzle orientation can easily lead to difficulties in subsequent processes. For example, it makes it difficult for the handling mechanism to move the tightened bottle from the turntable to the conveyor line, and it also hinders the consistency requirements of subsequent packing equipment. Therefore, we propose a new solution that ensures that each nozzle is always in a uniform orientation, thereby solving the problem of nozzle caps in automated packaging lines.

[0034] Please see Figures 1-8The present invention provides an automatic rotary table machine for packaging mite-removing spray, including a machine body 1, a support frame 2 on the machine body 1, a vertically arranged servo motor 3 on the support frame 2, and a correction arm mechanism 4 on the output shaft of the servo motor 3. The correction arm mechanism 4 can push the nozzle to rotate around the circumference of the bottle body, and can stop the nozzle at a predetermined orientation position, so that the final orientation of each nozzle is at the predetermined orientation position, keeping the nozzles in a consistent state.

[0035] Specifically, the machine body 1 is arranged on the packaging line. Conventional existing actuators such as capping robots and screw-on robots are arranged on the machine body 1 in sequence. The machine body 1 can drive the upright bottle to move intermittently, so that the upright bottle passes through each corresponding actuator in sequence. Each upright bottle pauses briefly at the corresponding actuator's operating position. During the pause, the corresponding actuator completes the corresponding operation, such as the capping robot completing the capping of the corresponding bottle and the screw-on robot completing the screw-on of the corresponding bottle. When the pause ends, the machine body 1 drives the upright bottle to move intermittently to the next position, so that the bottle receives the corresponding actuator to complete the corresponding operation.

[0036] Among them, the support frame 2 is a horizontal plate structure, and its plate surface is parallel to the horizontal plane. The support frame 2 and the servo motor 3 are both located above the bottle body. The servo motor 3 is fixedly installed on the support frame 2. The servo motor 3 is a servo control motor, which can accurately control the number of rotations and the start and stop positions. The servo control motor is existing technology and will not be described in detail. The shaft of the output shaft of the servo motor 3 is located below the body of the servo motor 3. The servo motor 3 is in a vertical inverted state. The correction arm mechanism 4 can be driven by the servo motor 3 to rotate, and the center of the entire rotation trajectory loop overlaps with the center of the nozzle deflection.

[0037] In practical use, after the bottle cap with the nozzle is screwed onto the bottle body by the capping robot, the bottle body is pushed by the machine body 1 to the position below the servo motor 3. During the brief pause of the bottle body, the servo motor 3 drives the correction arm mechanism 4 to rotate around the circumference of the bottle body. The number of rotations is a positive integer, such as 1, 2, or 3 rotations. The nozzle of the bottle cap is located on the rotation trajectory of the correction arm mechanism 4. During the rotation of the correction arm mechanism 4, the correction arm mechanism 4 can contact the nozzle, thereby changing the orientation of the nozzle. When the servo motor 3 stops rotating after rotating to the predetermined number of rotations, the position of the nozzle is the preset position, so that the orientation of the nozzle is in the preset orientation position, which can ensure the consistency of the nozzle orientation and facilitate the normal operation of subsequent handling and packing processes.

[0038] In another embodiment of the present invention, the correction arm mechanism 4 includes a crossbar 4.1 that is fixed perpendicularly to the output shaft of the servo motor 3. A push rod unit 4.2 that is parallel to the output shaft of the servo motor 3 is fixed perpendicularly to the body of the crossbar 4.1. The push rod unit 4.2 is capable of rotating and pushing the nozzle.

[0039] Preferably, the push rod unit 4.2 includes a cylindrical tube 4.21 that is movably connected to the crossbar 4.1. Specifically, the crossbar 4.1 has an opening for the cylindrical tube 4.21 to pass through. A protruding ring 20 is fixedly sleeved on the top of the cylindrical tube 4.21. A spring 21 is provided between the protruding ring 20 and the top of the crossbar 4.1. The spring 21 is movably sleeved on the cylindrical tube 4.21. A sliding sleeve 4.22 is movably sleeved on the outside of the cylindrical tube 4.21. The sliding sleeve 4.22 can rotate axially outside the cylindrical tube 4.21, thereby reducing the sliding friction force when the tube 4.21 contacts and pushes against the side of the nozzle. The crossbar 4.1 and the push rod unit 4.2 form a number "7" shaped structure.

[0040] During the rotation of the correction arm mechanism 4, its trajectory line forms a dome shape above the bottle body. The push rod unit 4.2 forms a dome-shaped side wall, so that the push rod unit 4.2 can push the nozzle that extends out of the dome shape, causing the nozzle to deflect around the bottle body.

[0041] In another embodiment of the present invention, a square tube 5 is vertically fixed to the bottom end of a circular tube 4.21. The length direction of the square tube 5 is perpendicular to the length direction of the crossbar 4.1. A toothed column 6 extending into the square tube 5 is rotatably installed inside the circular tube 4.21. Preferably, the toothed column 6 includes a cylindrical rod 6.1, a hard toothed ring 6.2 fixed to the top end of the cylindrical rod, and a torque toothed ring 6.3 installed at the lower end of the cylindrical rod 6.1. The ring of the torque toothed ring 6.3 is located inside the square tube 5. When the torque toothed ring 6.3 exceeds a certain torque value, it will slip accordingly. Within its torque value, the torque toothed ring 6.3 can be engaged and driven. The bottom of the support frame 2 is provided with an annular toothed groove 7 that is adapted to mesh with the top end of the toothed column 6. Two racks 8 are provided inside the square tube 5 that mesh symmetrically with the toothed column 6. The length direction of the racks 8 is parallel to the length direction of the square tube 5. The bar of the rack 8 slides in contact with the inner wall of the square tube 5. Each end of the square tube 5 is provided with a clamping bar 9 fixed to the end of the rack 8. The two clamping bars 9 are parallel to each other. The length direction of the bar of the clamping bar 9 is parallel to the cross bar 4.1 and perpendicular to the square tube 5. When the two clamping bars 9 are close to each other, they can clamp the side of the screw cap of the nozzle.

[0042] It should be further explained that the annular tooth groove 7 includes an annular groove body 7.1. A first tooth groove line 7.2 is formed on the inner annular wall of the annular groove body 7.1, and a second tooth groove line 7.3 is formed on the outer annular wall of the annular groove body 7.1. The sum of the arc of the first tooth groove line 7.2 and the arc of the second tooth groove line 7.3 is 360 degrees. The first tooth groove line 7.2 and the second tooth groove line 7.3 are connected end to end. The ratio of the arc of the first tooth groove line 7.2 to the arc of the second tooth groove line 7.3 is 1:1, or the ratio of the arc of the first tooth groove line 7.2 to the arc of the second tooth groove line 7.3 is 1:3 or 1:2, or the ratio is 1:N, where N is a positive integer. Specifically, the first tooth groove line 7.2 and the second tooth groove line 7.3 refer to the tooth structure that is continuously distributed on the groove sidewall of the groove body. The tooth surface formed by the tooth structure can be adapted to mesh with the teeth of the hard tooth ring 6.2 on the tooth post 6.

[0043] In actual use, when the bottle reaches the operating position of the correction arm mechanism 4, the servo motor 3 drives the crossbar 4.1 to rotate in a circle, which in turn drives the circular tube 4.21 to rotate in a corresponding synchronous circle. At this time, the toothed column 6 inside the circular tube 4.21 will also slide along the annular groove 7.1. During the sliding of the toothed column 6 in the annular groove 7.1, the hard toothed ring 6.2 at the top of the toothed column 6 can mesh with the first toothed groove line 7.2 and the second toothed groove line 7.3 in sequence.

[0044] When the hard toothed ring 6.2 at the top of the toothed column 6 meshes with the first tooth groove line 7.2, the toothed column 6 rotates axially in the forward direction. At this time, the rack 8 retracts into the square tube 5 under the meshing transmission of the torque toothed ring 6.3, thereby reducing the distance between the two clamping strips 9, thus clamping the side of the screw cap on the bottle body. When the distance between the two clamping strips 9 cannot be further reduced, the two clamping strips 9 are in a clamped state. If the hard toothed ring 6.2 at the top of the toothed column 6 is still meshed with the first tooth groove line 7.2, the torque toothed ring 6.3 located in the square tube 5 will slide in the forward direction. The torque toothed ring 6.3 is essentially a torque ring. Torque rings are existing technology and will not be described in detail.

[0045] It should be noted that when the two clamping strips 9 are in the clamping state, the clamping strips 9 also rotate in a circular motion with the crossbar 4.1, which can apply a tightening force to the bottle cap on the bottle body. This is beneficial for checking the tightness of the bottle cap on the bottle body and realizing secondary tightening, which helps to avoid the situation where the bottle cap is not tightened, and thus helps to avoid leakage.

[0046] In addition, long slots 17 are provided on the sides of both ends of the square tube 5 to slide and adapt to the clamping strips 9. The length direction line of the long slots 17 is parallel to the length direction line of the square tube 5. Preferably, one end of the long slots 17 can be connected to the tube opening of the square tube 5. The side of the clamping strip 9 is provided with a through-hole 18. There are two clamping strips 9 and two racks 8. One end of the rack 8 is fixed to the clamping strip 9, and the other end of the rack 8 is fixed with an extension rod 19 that is adapted to be inserted into the through-hole 18. Specifically, the first rack 8 is fixed to the first clamping strip 9, and the extension rod 19 on the first rack 8 moves through the through-hole 18 on the second clamping strip 9. Similarly, the second clamping strip 9 is fixed to the second rack 8, and the extension rod 19 on the second rack 8 moves through the through-hole 18 on the first clamping strip 9.

[0047] Similarly, when the hard toothed ring 6.2 meshes with the second tooth groove line 7.3, the toothed column 6 rotates in the opposite direction axially. At this time, the rack 8 extends towards the outer end of the square tube 5 under the meshing transmission of the torque toothed ring 6.3, thereby increasing the distance between the two clamping bars 9 and releasing the clamping bars 9 from the screw cap side of the cap. If the hard toothed ring 6.2 at the top of the toothed column 6 is still meshed with the second tooth groove line 7.3, the torque toothed ring 6.3 located in the square tube 5 will slide in the opposite direction.

[0048] In another embodiment of the present invention, a plurality of roller grooves 10 are provided on the side of the bar 9, and a rotating roller 11 is adapted to be provided in each roller groove 10. The axis of the rotating roller 11 is parallel to the axis of the cylindrical tube 4.21. A rubber layer is fixedly sleeved on the circumference of the roller body of the rotating roller 11. The rotating roller 11 and the roller groove 10 are rotatably connected through a damping bushing 12.

[0049] In practical use, when the two clamping strips 9 are in a clamped state and the bottle cap is being screwed on, even when the bottle cap and bottle body are already screwed on, the two clamping strips 9 are still rotating in a circular motion with the crossbar 4.1, and the hard toothed ring 6.2 at the top of the toothed column 6 is still meshed with the first toothed groove line 7.2. Therefore, the static friction between the clamping strips 9 and the bottle cap becomes sliding friction, which will undoubtedly increase the wear between the bottle cap and the clamping strips 9. Therefore, by adding a rotating roller 11, a roller groove 10 and a damping bushing 12 to the clamping strips 9, when the bottle cap and bottle body are already screwed on, the two clamping strips 9 are still rotating in a circular motion with the crossbar 4.1. The rotating roller 11 overcomes the resistance of the damping bushing 12 and rolls in the roller groove 10, converting the sliding friction between the clamping strips 9 and the bottle cap into rolling friction, thereby further reducing the wear of the bottle cap and reducing the resistance of the clamping strips 9 rotating around the bottle cap.

[0050] In another embodiment of the present invention, a turntable 1.1 capable of intermittent rotation is arranged on the machine body 1. The surface of the turntable 1.1 is parallel to the horizontal plane. A bottle slot 1.2 capable of axially limiting the rotation of the bottle is installed on the turntable 1.1. The bottle slot 1.2 can transport the bottle to the clamping area of ​​two clamping strips 9, thereby ensuring that the bottle can always remain upright during the transfer process on the machine body 1. The bottle slots 1.2 are evenly arranged on the edge contour line of the turntable 1.1. The groove of the bottle slot 1.2 is tangent to the edge of the turntable 1.1. The bottle slot 1.2 forms a slot on the edge contour line of the turntable 1.1. The bottle in the bottle slot 1.2 can be released through the slot on the edge contour line.

[0051] It should be further explained that a corner cylinder 22 is installed on the machine body 1. The output shaft of the corner cylinder 22 is fixed to the support frame 2. The installation of the corner cylinder 22 can transfer the bottle from the machine body 1 to another product conveyor belt through the correction arm mechanism 4. The belt plane on the product conveyor belt is lower than the placement plane of the turntable 1.1. That is to say, in the vertical direction, the position height of the bottle on the machine body 1 is greater than the position height of the bottle on the conveyor belt.

[0052] Specifically, the stroke trajectory of the output shaft of the corner cylinder 22 consists of a vertical movement stage and a horizontal movement stage. In actual use, when the two clamping bars 9 are in the clamping state, the corner cylinder 22 moves in its forward stroke. Specifically, the output shaft of the corner cylinder 22 first moves horizontally in a forward deflection, thereby driving the bottle to move out of the slot on the side of the bottle slot 1.2 through the correction arm mechanism 4, so that the bottle is separated from the turntable 1.1. Then, the output shaft of the corner cylinder 22 drives the bottle to move vertically in a forward direction, thereby placing the bottle on a new conveyor belt. At this time, the two clamping bars 9 are also released and separated from the bottle. Then, the corner cylinder 22 moves in its reverse stroke. Specifically, the output shaft of the corner cylinder 22 moves vertically in a reverse direction, and the bottle is conveyed on a new conveyor belt. Then, it moves horizontally in a reverse deflection. At this time, the correction arm mechanism 4 returns to the initial position, waiting to perform the above operation on the next bottle.

[0053] In another embodiment of the present invention, annular grooves 13 are provided on both the inner and outer walls of the annular groove 7.1. The annular contours of the two annular grooves 13 are on the same horizontal plane. A limiting ring 14 adapted to the annular groove 13 is provided in the annular groove 7.1. The annular opening of the limiting ring 14 is perpendicular to the axis of the tooth column 6. The column of the tooth column 6 moves through the annular body of the limiting ring 14. A baffle 15 fixed to the column of the tooth column 6 is provided on each side of the limiting ring 14. The baffle 15 makes the tooth column 6 and the limiting ring 14 rotate in a rotating connection state, preventing the tooth column 6 from disengaging from the annular groove 7.1. Furthermore, a plurality of evenly arranged balls 16 are installed on the annular body of the limiting ring 14. The balls 16 can reduce the sliding friction between the limiting ring 14 and the annular groove 13.

[0054] In actual use, when the toothed column 6 slides along the annular groove 7.1, in addition to the rotation generated by the toothed column 6 meshing with the first tooth groove line 7.2 and the second tooth groove line 7.3, the toothed column 6 also drives the limiting ring 14 to rotate on the annular limiting groove 13. The rolling ball 16 can reduce the sliding friction between the limiting ring 14 and the annular limiting groove 13, and at the same time, it can make the toothed column 6 and the support frame 2 have a certain connection force, so that it can work with the servo motor 3 to connect and pull the correction arm mechanism 4.

[0055] In another embodiment of the present invention, the rack 8 is an oblique rack body, that is, the teeth on the side of the rack 8 are in an inclined state, the angle between the length direction line of the teeth and the length direction line of the rack 8 is 45 degrees, the torsion ring 6.3 has a movable space in the square tube 5 along the axial direction of the tooth column 6, the length of the teeth of the torsion ring 6.3 is less than the length of the teeth of the rack 8, and the teeth of the torsion ring 6.3 can slide relative to each other along the tooth grooves of the teeth of the rack 8;

[0056] In actual use, when the output shaft of the corner cylinder 22 drives the bottle to move vertically forward, under the action of gravity, the gear column 6 drives the torque gear ring 6.3 to move vertically upward inside the square tube 5, so that the torque gear ring 6.3 contacts the inner top wall of the square tube 5. During this movement, the torque gear ring 6.3 slides relative to the tooth groove of the rack 8. Since the teeth on the side of the rack 8 are in an inclined state, the component force generated when the teeth of the torque gear ring 6.3 slide in the inclined tooth groove of the rack 8 can make the rack 8 have a driving force along the length of the square tube 5, thereby making the two adjacent clamping bars 9 have a further clamping force, further improving the clamping force on the bottle and preventing the bottle from slipping during the transfer. The bottle referred to here is the state where the bottle cap has been screwed on the bottle, which facilitates the vertical handling of the bottle.

[0057] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
