Description

Technical Field

[0001] This invention relates to the technical field of filling equipment, and in particular to a positioning and conveying method for multi-station filling bottles. Background Technology

[0002] Filling is an integral part of industrial production. In a filling production line, bottles need to be transported in an orderly manner. Compared to manual operation, existing filling systems often use conveyor belts for transportation, which offers a higher degree of automation. For example, the aseptic liquid filling machine with patent application number 201420671011.8 includes a frame, on which a conveying mechanism, a filling mechanism, a stoppering mechanism, and a stopper delivery mechanism are installed. The conveying mechanism transports glass bottles to various workstations for filling and stoppering. This machine has a high degree of automation, reduces labor intensity, and improves work efficiency. However, it places higher demands on the positioning accuracy of the conveying mechanism, requiring the glass bottles to be transported directly below each workstation.

[0003] In the filling process of aerosols or creams, due to the numerous process steps and the many stations involved in setting up and conveying, traditional linear bottle feeding mechanisms cannot position the cans accurately. Their positioning accuracy is poor, and they cannot ensure that the bottles are precisely delivered to the bottom of each station, thus hindering the normal operation of each station. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the background art mentioned above, and to provide a positioning and conveying method for multi-station filling bottles. By cooperating with the bottle clamping assembly and the bottle moving assembly, the positioning and conveying of filling bottles is realized, ensuring that each filling bottle is conveyed directly below the preset station, which facilitates the normal operation of each station, ensures the reliability and stability of the filling operation, and thus improves the efficiency and automation of the work.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a positioning and conveying method for multi-station filling bottles. The positioning and conveying method is based on a reciprocating bottle feeding mechanism for multi-station filling bottles. The reciprocating bottle feeding mechanism includes: a channel support and a support plate disposed at one end of the channel support. A motor bracket is disposed in the middle of the channel support. Bottle inlet channels are disposed on both sides of the channel support. A spiral bottle feeding mechanism is disposed in the bottle inlet channel. A bottle transfer drive assembly and a gripper motor are disposed on the motor bracket, and the gripper motor is located above the bottle transfer drive assembly.

[0006] The support plate is provided with a bottle clamping assembly and a bottle transfer assembly. The bottle clamping assembly is located above the bottle transfer assembly. The bottle transfer assembly includes a bottle transfer fixing plate that is slidably connected to the support plate. The output end of the bottle transfer driving assembly is connected to the bottle transfer fixing plate.

[0007] The steps of the positioning and conveying method are as follows:

[0008] S1. The spiral bottle feeding mechanism transports the filled bottles at equal intervals to the first station of the bottle feeding channel;

[0009] S2. The bottle clamping assembly operates to clamp the filling bottle in the bottle feeding channel. Since the clamping claw inside the bottle clamping assembly has an arc-shaped structure, it automatically guides the filling bottle to a unique position and clamps it, thus completing the clamping and positioning action of the filling bottle.

[0010] S3. The process operation at the upper end of the first station is started, and the filling bottles in the first station are processed.

[0011] S4. The bottle transfer drive component moves the bottle held in S2 forward one station to complete the precise positioning and conveying of one station. At this time, the bottle in the first station is conveyed to the second station. The bottle clamping component moves again to release the bottle. The bottle transfer drive component moves again to return to the initial position.

[0012] S5. The spiral bottle feeding mechanism operates, conveying another filling bottle to the first station of the bottle feeding channel;

[0013] S6. The bottle clamping assembly is activated to clamp the filling bottles at the first and second workstations. The process operation at the upper end of the first workstation is started to perform the process operation on the filling bottles at the first workstation. At the same time, the process operation at the upper end of the second workstation is also started to perform the process operation on the filling bottles at the second workstation.

[0014] S7. Repeat the steps in S4. At this time, the bottles in the first station are transported to the second station, and the bottles in the second station are transported to the third station.

[0015] S8. Repeat steps S5 and S6 until all stations in the bottle feeding channel are carrying bottles. At this point, all processes at the top of the bottle feeding channel will be operating synchronously, completing the synchronous operation of the process corresponding to each station of the bottle filling.

[0016] The bottle clamping assembly includes clamping jaw fixing plates slidably connected to both sides of the bottle transfer fixing plate. Multiple sets of inner arc-shaped clamping jaws are provided on the outer side of the clamping jaw fixing plates. Two sets of bearing seats are provided in the middle of the bottle transfer fixing plate. A clamping jaw telescopic transmission shaft sleeve is rotatably mounted on the upper end of each bearing seat. A clamping jaw shifting main gear is keyed to the middle of the clamping jaw telescopic transmission shaft sleeve. Two sets of transmission shaft supports are provided on the support plate, and the transmission shaft supports are respectively located on the outer side of the bearing seats. A clamping jaw telescopic transmission shaft is rotatably mounted on each of the two transmission shaft supports. The clamping jaw telescopic transmission shaft sleeve is slidably fitted onto the outside of the clamping jaw telescopic transmission shaft. One end of the clamping jaw telescopic transmission shaft is connected to the clamping jaw motor.

[0017] A rotatable jaw telescopic screw is rotatably mounted at the lower end of the bearing housing. A jaw shifting driven gear is keyed to the middle of the jaw telescopic screw, and the jaw shifting driven gear meshes with the jaw shifting main gear. Both ends of the jaw telescopic screw are provided with a lead screw nut, which moves synchronously towards or away from each other. Each lead screw nut is provided with a jaw opening and closing linkage bracket, and both ends of the jaw opening and closing linkage bracket are hinged to a jaw opening and closing linkage. The other end of the jaw opening and closing linkage is hinged to the jaw fixing plate. The jaw shifting main gear drives the jaw shifting driven gear to rotate, thereby causing the two lead screw nuts to move synchronously towards or away from each other, realizing the swing of the jaw opening and closing linkage, and thus moving the jaw fixing plate, which in turn achieves the movement of the jaw.

[0018] Preferably, the support plate is provided with an outer bottle stop baffle and an inner bottle stop baffle on both outer sides, and a bottle feeding channel is formed between the outer bottle stop baffle and the inner bottle stop baffle. The bottle feeding channel and the bottle inlet channel are located on the same straight line for positioning and conveying the filling bottles.

[0019] Furthermore, the support plate is provided with two sets of bracket plates, and a servo drive shaft is rotatably mounted on the two bracket plates. The gripper telescopic drive shaft is connected to the gripper motor through the servo drive shaft. Both ends of the servo drive shaft are provided with couplings, forming a flexible connection, which makes installation simpler and more convenient.

[0020] Furthermore, the outer surface of the gripper telescopic drive shaft is hexagonal (i.e., the cross-section of the middle part of the gripper telescopic drive shaft is hexagonal). The gripper telescopic drive shaft sleeve is slidably fitted on the outside of the gripper telescopic drive shaft. The gripper motor drives the gripper telescopic drive shaft to rotate through the servo drive shaft. The gripper telescopic drive shaft uses the hexagonal structure to drive the gripper telescopic drive shaft sleeve to rotate, thereby driving the gripper shifting main gear to rotate. The hexagonal structure of the outer surface of the gripper telescopic drive shaft not only transmits torque but also guides, allowing the gripper telescopic drive shaft sleeve to slide smoothly on the gripper telescopic drive shaft.

[0021] Furthermore, the bottle transfer drive assembly includes a bottle transfer drive motor and a bottle transfer servo electric cylinder connected to the output end of the bottle transfer drive motor, which has higher control precision.

[0022] Furthermore, a limiting slider is provided at the lower end of each of the two lead screw nuts, and a guide limiting rod is provided between the two bearing seats. The limiting slider is slidably engaged with the guide limiting rod to ensure that the lead screw nuts move smoothly back and forth.

[0023] Furthermore, the bottle transfer fixing plate and the support plate, as well as the gripper fixing plate and the bottle transfer fixing plate, both use stainless steel sanitary-grade oil-free maintenance-free linear guides. The overall mechanism material can be 304 stainless steel, and the gears are made of PEEK (polyether ether ketone) material, thereby meeting sanitary requirements.

[0024] The design principle of this invention is as follows: By setting up a bottle clamping assembly, the clamping jaw motor drives the clamping jaw telescopic transmission shaft to rotate via a servo transmission shaft. The hexagonal structure of the clamping jaw telescopic transmission shaft drives the clamping jaw telescopic transmission shaft sleeve to rotate, thereby driving the clamping jaw displacement main gear to rotate. The clamping jaw displacement main gear drives the clamping jaw displacement slave gear to rotate, thereby driving the two lead screw nuts to move synchronously towards each other or synchronously away from each other, realizing the swing of the clamping jaw opening and closing linkage, and thus driving the clamping jaw fixing plate to move, that is, realizing the movement of the clamping jaw. The clamping jaw pushes the filling bottle in the bottle feeding channel to the inner side wall of the outer bottle stop baffle, completing the clamping and positioning action of the filling bottle. At this time, the bottle transfer drive assembly starts to work. The bottle transfer drive motor drives the bottle transfer servo electric cylinder to move, the bottle transfer servo electric cylinder drives the bottle transfer fixing plate to move, and the clamping jaw fixing plate and bearing seat on the bottle transfer fixing plate move together. The clamping jaw telescopic transmission shaft sleeve slides on the clamping jaw telescopic transmission shaft, thus completing the conveying of one station.

[0025] The beneficial effects of the present invention are: (1) By cooperating with the bottle clamping assembly and the bottle transfer assembly, the positioning and conveying of the filling bottles are realized, ensuring that each filling bottle is conveyed to the bottom of the preset work station and the conveying position is unique, which facilitates the normal operation of each work station, ensures the reliability and stability of the filling operation, and thus improves the work efficiency and automation level; (2) Before the corresponding process of each work station performs the process operation on the filling bottle at its lower end, the bottle clamping assembly clamps the filling bottle, and the filling bottle is in a positioning state, making its process operation more reliable, thereby ensuring the quality of filling.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0032] like Figures 1 to 3 As shown, a positioning and conveying method for multi-station filling bottles is disclosed. The positioning and conveying method is based on a reciprocating bottle feeding mechanism for multi-station filling bottles. The reciprocating bottle feeding mechanism includes a channel support 100 and a support plate 200 disposed at one end of the channel support 100. A motor bracket 300 is disposed in the middle of the channel support 100. Bottle inlet channels 400 are disposed on both sides of the channel support 100. A spiral bottle feeding mechanism 401 is disposed in the bottle inlet channel 400. A bottle transfer drive assembly 500 and a gripper motor 600 are disposed on the motor bracket 300, and the gripper motor 600 is located above the bottle transfer drive assembly 500.

[0033] The support plate 200 is provided with a bottle clamping assembly 700 and a bottle transfer assembly 800. The bottle clamping assembly 700 is located above the bottle transfer assembly 800. The bottle transfer assembly 800 includes a bottle transfer fixing plate 801 slidably connected to the support plate 200. The output end of the bottle transfer driving assembly 500 is connected to the bottle transfer fixing plate 801.

[0034] The bottle clamping assembly 700 includes a clamping jaw fixing plate 701 slidably connected to both sides of the bottle transfer fixing plate 801. Multiple sets of inner arc-shaped clamping jaws 702 are provided on the outer side of the clamping jaw fixing plate 701. Two sets of bearing seats 703 are provided in the middle of the bottle transfer fixing plate 801. A clamping jaw telescopic transmission shaft sleeve 704 is rotatably mounted on the upper end of each bearing seat 703. A clamping jaw shifting main gear 705 is keyed to the middle of the clamping jaw telescopic transmission shaft sleeve 704. Two sets of transmission shaft supports 706 are provided on the support plate 200, and the transmission shaft supports 706 are respectively located on the outer side of the bearing seats 703. A clamping jaw telescopic transmission shaft 707 is rotatably mounted on each of the two transmission shaft supports 706. The clamping jaw telescopic transmission shaft sleeve 704 is slidably sleeved on the outside of the clamping jaw telescopic transmission shaft 707. The support plate 200 is also provided with two sets of bracket plates 708. A servo drive shaft 709 is rotatably mounted on the two bracket plates 708. The gripper telescopic drive shaft 707 is connected to the gripper motor 600 through the servo drive shaft 709. Both ends of the servo drive shaft 709 are provided with couplings 710, which form a flexible connection, making installation simpler and more convenient.

[0035] A gripper telescopic screw 711 is rotatably mounted on the lower end of the bearing housing 703. A gripper shifting follower gear 712 is keyed to the middle of the gripper telescopic screw 711. The gripper shifting follower gear 712 meshes with the gripper shifting main gear 705. A screw nut 713 is provided at both ends of the gripper telescopic screw 711. The two screw nuts 713 move synchronously towards each other or synchronously away from each other. A gripper opening and closing linkage bracket 714 is provided on both screw nuts 713. A gripper opening and closing linkage 715 is hinged to both ends of the gripper opening and closing linkage bracket 714. The other end of the gripper opening and closing linkage 715 is hinged to the gripper fixing plate 701. The main gear 705 drives the jaw shifting gear 712 to rotate, thereby causing the two lead screw nuts 713 to move synchronously towards each other or synchronously away from each other, realizing the swing of the jaw opening and closing linkage 715, which in turn drives the jaw fixing plate 701 to move, that is, realizing the movement of the jaw 702.

[0036] The support plate 200 is provided with an outer bottle stop baffle 901 and an inner bottle stop baffle 902 on both outer sides. A bottle feeding channel 900 is formed between the outer bottle stop baffle 901 and the inner bottle stop baffle 902. The bottle feeding channel 900 is located on the same straight line as the bottle inlet channel 400 and is used for positioning and conveying the filling bottles.

[0037] The outer surface of the gripper telescopic drive shaft 707 is hexagonal. The gripper telescopic drive shaft sleeve 704 is slidably fitted on the outside of the gripper telescopic drive shaft 707. The gripper motor 600 drives the gripper telescopic drive shaft 707 to rotate via the servo drive shaft 709. The gripper telescopic drive shaft 707 uses the hexagonal structure to drive the gripper telescopic drive shaft sleeve 704 to rotate, thereby driving the gripper shifting main gear 705 to rotate. The hexagonal design of the outer surface of the gripper telescopic drive shaft 707 not only transmits torque but also guides, allowing the gripper telescopic drive shaft sleeve 704 to slide smoothly on the outside of the gripper telescopic drive shaft 707.

[0038] The bottle transfer drive assembly 500 includes a bottle transfer drive motor 501 and a bottle transfer servo electric cylinder 502 connected to the output end of the bottle transfer drive motor 501, which has higher control precision.

[0039] Each of the two lead screw nuts 713 is provided with a limiting slider 716 at its lower end, and a guide limiting rod 717 is provided between the two bearing seats 703. The limiting slider 716 is slidably engaged with the guide limiting rod 717 to ensure that the lead screw nut 713 moves smoothly back and forth.

[0040] The bottle transfer fixing plate 801 and the support plate 200, as well as the gripper fixing plate 701 and the bottle transfer fixing plate 801, all use stainless steel sanitary oil-free maintenance-free linear guides. The overall mechanism material can be 304 stainless steel. The gripper shifting main gear 705 and the gripper shifting driven gear 712 are made of PEEK (polyether ether ketone), thus meeting the sanitary requirements and being suitable for reciprocating bottle delivery operations requiring a sterile environment.

[0041] like Figure 3 As shown, the present invention is installed in a multi-station filling device during use. Figure 3 The middle section (showing only a portion of the structure) has corresponding work processes above each station, such as: bottle mouth spraying (for bottle mouth sterilization), bottle inside spraying (for bottle inside sterilization), bottle inside drying, bottle inside cooling, liquid filling, valve installation, sealing, and gas filling.

[0042] like Figures 1 to 3 As shown, the steps for using it are as follows:

[0043] S1, the spiral bottle feeding mechanism 401 conveys the filled bottles at equal intervals to the first station 1000 of the bottle feeding channel 900;

[0044] S2. The bottle clamping assembly 700 operates to clamp the filling bottle in the bottle feeding channel 900. Since the clamping jaw 702 inside the bottle clamping assembly 700 has an arc-shaped structure, it automatically guides the filling bottle to a unique position and clamps it, thus completing the clamping and positioning action of the filling bottle.

[0045] S3. The process operation at the upper end of the first station 1000 is started, and the process operation is carried out on the filling bottles in the first station 1000;

[0046] S4. The bottle transfer drive assembly 500 is activated, moving the bottle clamped in S2 forward one station to complete the precise positioning and conveying of one station. At this time, the bottle in the first station 1000 is conveyed to the second station 1100. The bottle clamping assembly 700 is activated again to release the clamped bottle. The bottle transfer drive assembly 500 is activated again to drive the bottle transfer fixing plate 801 and its components back to the initial position.

[0047] S5. The spiral bottle feeding mechanism 401 operates again, conveying another filling bottle to the first station 1000 of the bottle feeding channel 900.

[0048] S6. The bottle clamping assembly 700 is activated to clamp the filling bottles located at the first station 1000 and the second station 1100. The process operation at the upper end of the first station 1000 is started to perform the process operation on the filling bottles in the first station 1000. At the same time, the process operation at the upper end of the second station 1100 is also started to perform the process operation on the filling bottles in the second station 1100.

[0049] S7. Repeat the steps in S4. At this time, the filling bottles in the first station 1000 are conveyed to the second station 1100, and the filling bottles in the second station 1100 are conveyed to the third station 1200.

[0050] S8. Repeat steps S5 and S6 until all stations in the bottle feeding channel 900 are carrying bottles. At this point, all processes at the top of the bottle feeding channel 900 will be operating synchronously, completing the synchronous operation of the process corresponding to each station of the bottle filling.

[0051] During use, the gripper motor 600 drives the gripper telescopic drive shaft 707 to rotate via the servo drive shaft 709. The gripper telescopic drive shaft 707, with its hexagonal structure, drives the gripper telescopic drive shaft sleeve 704 to rotate, thereby driving the gripper shifting main gear 705 to rotate. The gripper shifting main gear 705 drives the gripper shifting slave gear 712 to rotate, thereby driving the two lead screw nuts 713 to move synchronously towards each other or synchronously away from each other, realizing the swing of the gripper opening and closing linkage 715, and further driving the gripper fixing plate 701 to move, thus realizing the movement of the gripper 700. As the bottle moves, the gripper 702 pushes the bottle in the bottle feeding channel 900 to the inner wall of the outer bottle stop plate 901, completing the clamping and positioning action of the bottle. At this time, the bottle transfer drive assembly 500 starts to work, the bottle transfer drive motor 501 drives the bottle transfer servo cylinder 502 to move, the bottle transfer servo cylinder 502 drives the bottle transfer fixing plate 801 to move forward, and the gripper fixing plate 701 and bearing seat 703 on the bottle transfer fixing plate 801 move forward together. The gripper 702 moves the clamped bottle forward one station, completing the precise positioning and conveying of one station. After each station's operation (spraying, drying, cooling, filling, valve installation, sealing, inflation, etc.) is completed, the gripper motor 600 rotates in reverse, the gripper 702 retracts, and then the bottle transfer drive motor 501 rotates in reverse. The bottle transfer servo cylinder 502 drives the gripper fixing plate 701 and the gripper 702 to move backward, returning to the initial state and waiting for the next cycle. In this way, the filled bottles are positioned and transported to each station, completing the corresponding process operation for each station.

[0052] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
