Description

Technical Field

[0001] This invention belongs to the field of packaging equipment technology, and in particular relates to a bottle sorting, palletizing and boxing machine. Background Technology

[0002] Currently, infusion bottles in the pharmaceutical field are generally divided into two types: rigid bottles and flexible bottles. Rigid bottles are mostly made of glass. However, due to the poor stability, susceptibility to glass shards, and high risk of secondary contamination associated with glass bottles, flexible bottles have seen increasing application in the pharmaceutical field with technological advancements. Flexible bottles mainly consist of three parts: the bottle body, the neck, and the cap. The bottle body is relatively soft. In the infusion production line, flexible bottles undergo filling, sterilization, labeling, and packaging processes in sequence.

[0003] In automated packing operations, there are two main packing methods for bottles: one is to pack individual bottles into cartons; the other is to pack bottles into the cavities of a bottom tray and a top tray, where the bottom tray has several arrayed support holes. For the latter, in existing technology, the bottom tray is first placed into a carton, and then a bottle conveying device transports the bottles at preset intervals to the end of the device. A packing robot is located at the end of the conveying device, which then picks up the bottles and inserts them into the support holes of the bottom tray.

[0004] The latter bottling method described above is designed for glass pharmaceuticals made of glass. Because soft-sided bottles are relatively soft, the internal pressure after filling and sterilization can cause deformation and lead to tipping. Therefore, the aforementioned bottle conveying device cannot be used to transport soft-sided bottles at preset intervals. To achieve the palletizing and boxing of packaged soft-sided bottles, the existing technology involves manual palletizing, where each soft-sided bottle in a group is placed into the corresponding hole in the base tray. After completing one group, the worker waits for the next group, repeating this cycle. This process is time-consuming, slow, inefficient, and labor-intensive, resulting in high labor and management costs. Therefore, this semi-automated production method of manually placing soft-sided bottles into base trays has hindered market development. Summary of the Invention

[0005] This invention provides a bottle-sorting, palletizing, and case-packing machine with a reasonable structural design and a high degree of automation, addressing the technical problems existing in prior art. This invention improves production efficiency and reduces production management costs.

[0006] The technical solution adopted by this invention to solve the technical problems existing in the prior art is as follows: A bottle feeding and packaging machine includes a box supply assembly for conveying and opening packaging boxes; a foam transfer assembly for sequentially filling foam bottom trays and foam top trays into the packaging boxes; an array bottle feeding assembly for moving the packaged soft bottles conveyed by the chain conveyor line along the Y-axis to arrange them into a rectangular array; a Y-axis adjusting device provided at the discharge end of the array bottle feeding assembly for adjusting the spacing of the arrayed packaged soft bottles in the Y-axis direction at a preset interval; a spacing limiting device installed on the Y-axis adjusting device for pushing and limiting the packaged soft bottles on the Y-axis adjusting device in the X-axis direction; an X-axis adjusting device provided above the Y-axis adjusting device for grabbing the packaged soft bottles on the Y-axis adjusting device and adjusting the spacing in the X-axis direction at a preset interval; and a packaging assembly for driving the X-axis adjusting device to move and insert the grabbed packaged soft bottles into the bearing holes of the foam bottom tray.

[0007] The advantages and positive effects of this invention are as follows: This invention provides a bottle feeding and boxing machine. By setting up a box supply assembly, it can automatically transport and open the packaging boxes for feeding. By setting up a foam transfer assembly, it can sequentially fill the opened packaging boxes with foam bottom trays and foam top trays, eliminating the need for manual loading and improving work efficiency. By setting up an array bottle feeding assembly, it can move the packaged soft bottles transported by the chain conveyor line along the Y-axis to arrange them into a rectangular array. By setting up Y-axis and X-axis adjustment devices, it can adjust the spacing between adjacent rows and columns of the packaged bottle array, thereby ensuring that the position of the packaged bottles in the array meets the position of the bearing holes in the foam bottom tray. By setting up a boxing assembly, it can drive the X-axis adjustment device to move, thereby loading the packaged soft bottles it grabs into the bearing holes of the bottom tray. Repeated operation can realize multi-layer boxing of packaged bottles. This invention can automatically arrange and organize the packaging bottles conveyed by the transmission line, and adjust the spacing between adjacent rows and columns of the packaging bottle array according to the bearing holes in the foam base, thereby achieving precise packing of soft bottles into trays and enabling multi-layer packing operations. It eliminates the need for dedicated personnel to arrange and pack the bottles, saving manpower, reducing packaging costs and time, and significantly improving packaging efficiency.

[0036] To further understand the invention's content, features, and effects, the following embodiments are provided for detailed explanation:

[0037] Please see Figure 1 and Figure 2 The bottle-sorting, palletizing, and case-packing machine of the present invention includes a transverse support 21 and a bottle-sorting mounting frame 1, which are constructed by welding multiple sets of profiles perpendicularly to each other. The bottle-sorting mounting frame 1 is located below the transverse support 21. Two sets of X-axis linear guides 19 extending along the X-axis direction are fixedly connected to the transverse support 21, and two sets of Y-axis linear guides 5 extending along the Y-axis direction are fixedly connected to the bottle-sorting mounting frame 1. In addition, in order to protect the X-axis linear guides 19 and other components, this embodiment also includes a protective upright plate 20 installed on the top of the transverse support 21.

[0038] like Figure 1 As shown, this embodiment also includes a box supply assembly for conveying the packaging box 15 and opening the packaging box 15; it also includes a foam transfer assembly mounted on the transverse support 21 and movable along the X-direction linear guide rail 19 for sequentially filling the packaging box 15 with the foam bottom support 22 and the foam top support 23.

[0039] The foam base 22 and foam top 23 are made of elastic materials such as foam or shock-absorbing materials to provide good cushioning and shock absorption. The foam base 22 has several arrayed support holes for positioning and separating the packaging bottles 100 placed on it, and also for providing some support for the bottles. Figure 1As shown, most of the bearing holes are blind holes. For the style of the bearing holes and the distribution of the bearing holes on the foam base 22, please refer to the prior art, which will not be repeated here. In addition, a positioning blind hole (not shown) is provided on the foam top support 23, which corresponds to the position of the bearing hole on the foam base 22. The above-mentioned positioning blind hole is used to position the upper end of the packaging soft bottle 100 inserted in the bearing hole, thereby achieving a stable positioning operation of the packaging soft bottle 100.

[0040] See further Figure 2 This embodiment also includes an array bottle-scraping assembly mounted on the bottle-scraping mounting rack 1, used to move the packaged soft bottles 100 conveyed by the chain conveyor line 27 along the Y-axis direction to arrange them into a rectangular array. This embodiment also includes a Y-axis spacing adjustment device 10 mounted on the bottle-scraping mounting rack 1. The Y-axis spacing adjustment device 10 is located at the discharge end of the array bottle-scraping assembly. In actual operation, the Y-axis spacing adjustment device 10 is used to adjust the spacing of the arrayed packaged soft bottles 100 in the Y-axis direction at a preset interval. This embodiment also includes a spacing limiting device 9 mounted on the bottle-scraping mounting rack 1. The spacing limiting device 9 is located above the Y-axis spacing adjustment device 10 and is used to push and limit the packaged soft bottles 100 on the Y-axis spacing adjustment device 10 in the X-axis direction.

[0041] like Figure 1 As shown, this embodiment also includes an X-axis adjusting device 13 mounted on the transverse support 21. The X-axis adjusting device 13 is located above the Y-axis adjusting device 10. The X-axis adjusting device 13 is used to grip the packaging soft bottle 100 on the Y-axis adjusting device 10 and adjust the distance in the X direction at a preset interval. This embodiment also includes a packing assembly mounted on the transverse support 21, which drives the X-axis adjusting device 13 to move and load the gripped packaging soft bottle 100 into the bearing hole of the foam base 22.

[0042] like Figure 1 As shown, in this embodiment, the box supply assembly includes a box conveyor line 26 for conveying packaging boxes 15 along the Y-axis direction. The box supply assembly also includes a box support device 16 disposed above the box conveyor line 26, wherein the box support device 16 is mounted on a transverse support 21. The box support device 16 can open the box flaps of the packaging box 15 conveyed to the end of the box conveyor line 26, thereby facilitating subsequent palletizing and packing operations. When the packaging box 15 is conveyed to the packing station below the box support device 16 at the end of the box conveyor line 26, the box conveyor line 26 stops conveying.

[0043] See further Figure 15In this embodiment, the support device 16 includes two sets of horizontally parallel mounting square tubes 16-7 with adjustable spacing, and the overall height of the two sets of mounting square tubes 16-7 is adjustable. Specifically, four optical axis mounting parts 16-1 are detachably connected to the transverse support 21, and the four optical axis mounting parts 16-1 are respectively mounted on the four columns of the transverse support 21. Each optical axis mounting part 16-1 has a longitudinally extending strip hole. It also includes two sets of horizontally parallel mounting optical axes 16-3, and the longitudinal position of the two sets of mounting optical axes 16-3 is adjustable. That is, the end of the mounting optical axis 16-3 is locked to the optical axis mounting part 16-1 by bolts passing through the strip holes opened in the optical axis mounting parts 16-1.

[0044] like Figure 15 As shown, the support device 16 also includes two sets of axial mounting components 16-2 mounted on each mounting optical axis 16-3, the positions of which are adjustable in the axial direction; two sets of mounting square tubes 16-7 are disposed between the two sets of axial mounting components 16-2 and connected to the mounting optical axis 16-3 through the axial mounting components 16-2; wherein, the extending direction of the two sets of mounting square tubes 16-7 is perpendicular to the axial direction of each mounting optical axis 16-3.

[0045] See further Figure 17 In this embodiment, the axial mounting assembly 16-2 includes a transition mounting component 16-2-2, which has a right-angle structure and a locking mounting sleeve 16-2-3 and a square tube mounting sleeve 16-2-1 are respectively mounted on the two right-angle surfaces. The locking mounting sleeve 16-2-3 is fitted onto the mounting optical axis 16-3 and its position is adjustable. The square tube mounting sleeve 16-2-1 is used for detachably connecting the mounting square tube 16-7. That is, locking nuts are welded and fixed to all four sides of the square tube mounting sleeve 16-2-1, and bolts that penetrate the side wall of the square tube mounting sleeve 16-2-1 are screwed onto each locking nut. In the actual installation process, the ends of the bolts are in tight contact with the ends of the mounting square tube 16-7 that are inserted into the square tube mounting sleeve 16-2-1.

[0046] like Figure 15 As shown, the box-supporting device 16 also includes two sets of tubular mounting assemblies 16-6, each of which is adjustable in its length direction and mounted on each of the two sets of mounting square tubes 16-7. Each tubular mounting assembly 16-6 has a pivotally mounted box-supporting plate structure 16-5, and the four box-supporting plate structures 16-5 work together to form a box-supporting area. The box-supporting device 16 also includes a box-supporting cylinder 16-4 mounted on each tubular mounting assembly 16-6 to drive the corresponding box-supporting plate structure 16-5 to rotate.

[0047] See further Figure 16The tubular mounting assembly 16-6 includes a square tube sleeve 16-6-3 that passes through and slides in contact with the mounting square tube 16-7. A knob mounting member 16-6-2 is mounted on the square tube sleeve 16-6-3. A locking knob that passes through the side wall of the square tube sleeve 16-6-3 is screwed onto the knob mounting member 16-6-2. The locking knob is used to press the square tube sleeve 16-6-3 to fix its position. The tubular mounting assembly 16-6 also includes a connecting plate hinge member 16-6-4 fixed to the top surface of the square tube sleeve 16-6-3. The connecting plate hinge member 16-6-4 is used for pivotally mounting the support box structure 16-5. The pipe mounting assembly 16-6 also includes a mounting riser 16-6-1 fixed to the bottom surface of the square tube sliding sleeve 16-6-3 for mounting the support cylinder 16-4; that is, the cylinder of the support cylinder 16-4 is connected to the mounting riser 16-6-1 through a hinge seat and a pin, and the piston rod of the support cylinder 16-4 is pivotally connected to the support plate structure 16-5 through a Y-type joint and a pin.

[0048] In actual operation, the piston rod of the box-supporting cylinder 16-4 retracts, which can cause the lower end of the box-supporting plate structure 16-5 to tilt up, and then wait for the packaging box 15 to be transferred to the box-supporting area. When the packaging box 15 is transferred to the box-supporting area, the piston rod of the box-supporting cylinder 16-4 extends, which can cause the lower end of the box-supporting plate structure 16-5 to press down, thereby opening the box flaps of the packaging box 15 from the inside to the outside.

[0049] like Figure 16 As shown, in this embodiment, the box support structure 16-5 includes a swing connecting plate 16-5-2. The middle part of the swing connecting plate 16-5-2 is pivotally mounted to the connecting plate hinge 16-6-4, and the upper end is pivotally mounted to the piston rod of the box support cylinder 16-4. The box support structure 16-5 also includes two box support pressing plates 16-5-1 fixedly connected to the lower end of the swing connecting plate 16-5-2. The two box support pressing plates 16-5-1 correspond to two adjacent box flaps of the packaging box 15, respectively. The two box support pressing plates 16-5-1 correspond to two adjacent box flaps at the corner position of the packaging box 15. The box support structure 16-5 rotates into the packaging carton, opening the box flaps of the carton from the inside out. The two box support pressing plates 16-5-1 can also be used as material guide plates to facilitate the insertion of the packaging bottles into the carton. The angle between the two support plates 16-5-1 is an obtuse angle, which can better open the box flaps 15 of the packaging box outwards and prevent the box flaps from blocking the materials, making it easier for the materials to enter the box.

[0050] The foam transfer assembly is mounted on the transverse support 21. The foam transfer assembly includes a pick-and-place device 17, on which a loading and lifting device 18 for driving its longitudinal movement is mounted, and a loading and traversing device 11 mounted on the transverse support 21. The loading and traversing device 11 and the loading and lifting device 18 work together to drive the pick-and-place device 17 to move along the X-axis between the pick-and-place station and the loading station.

[0051] To improve the automation level of case packing machines, such as Figure 1 As shown, this embodiment also includes a top support conveyor line 24 and a bottom support conveyor line 25 arranged in parallel, which are used to transport the bottom support and the top support to the work station to be transferred, respectively; both the top support conveyor line 24 and the bottom support conveyor line 25 are roller conveyor lines and transport along the Y-axis direction; each roller conveyor line is equipped with a guardrail structure for limiting the products transported on it.

[0052] Further participation Figure 14 In this embodiment, the mounting transverse movement device 11 includes a mounting transverse movement seat 11-2 slidably connected to the X-direction linear guide rail 19 via a slider, and a mounting lifting device 18 mounted on the mounting transverse movement seat 11-2; it also includes a mounting pulley pair 11-3 and a mounting transverse movement motor 11-1 mounted on the transverse movement bracket 21, which together drive the mounting transverse movement seat 11-2 to move along the X-direction linear guide rail 19. The mounting pulley pair 11-3 includes a driving pulley and a driven pulley rotatably connected to both ends of the transverse movement bracket 21, respectively. A closed belt is connected between the driving pulley and the driven pulley, and the belt is connected to the mounting transverse movement seat 11-2. The mounting transverse movement motor 11-1 drives the driving pulley to rotate, that is, the output shaft of the mounting transverse movement motor 11-1 is connected to the driving pulley.

[0053] like Figure 14 As shown, in this embodiment, the loading and lifting device 18 includes a loading and lifting electric cylinder 18-3 with its extended end facing downward, which is connected to the loading and lifting transverse seat 11-2. A loading and lifting seat 18-1 is installed at the extended end of the loading and lifting electric cylinder 18-3. In order to improve the stability of the lifting and moving of the loading and lifting seat 18-1, the loading and lifting device 18 also includes a longitudinally arranged loading guide rod 18-2 installed on the loading and lifting seat 18-1. The loading guide rod 18-2 is slidably connected to the loading and lifting transverse seat 11-2 through a linear bearing.

[0054] See further Figure 18To facilitate the placement and removal of the foam base tray 22 and the foam top tray 23, in this embodiment, the placement and removal device 17 includes a mounting frame structure connected to the mounting lifting seat 18-1 in the mounting lifting device 18; a push plate cylinder 17-6 with its extended end facing downward is connected to the mounting frame structure, and a push plate 17-1 is connected to the extended end of the push plate cylinder 17-6; the mounting frame structure specifically includes a lifting connecting pipe 17-5 fixedly connected to the mounting lifting seat 18-1 in the mounting lifting device 18, a push plate cylinder seat 17-4 fixedly connected to the lower end of the lifting connecting pipe 17-5, the cylinder of the push plate cylinder 17-6 being connected to the push plate cylinder seat 17-4, and also includes a pin mounting seat 17-7 fixedly connected to the push plate cylinder seat 17-4.

[0055] To accommodate the insertion and removal of the foam base 22 and foam top 23, the placement and removal device 17 further includes multiple sets of horizontally parallel pin mounting structures 17-3 mounted on the pin mounting base 17-7. Each pin mounting structure 17-3 can be detachably mounted with multiple sets of horizontally parallel pins 17-2, each pin 17-2 penetrating a corresponding through hole in the push plate 17-1. Each pin mounting structure 17-3 includes two opposing sets of pin mounting strips, each with an arc groove on its opposing surface. The pins 17-2 are embedded in these arc grooves. The two sets of pin mounting strips are detachably connected by bolts, thereby clamping the multiple sets of pins 17-2 positioned between the two sets of pin mounting strips. Each pin mounting structure 17-3 is detachably connected to the pin mounting base 17-7 by bolts.

[0056] The working principle of the pick-and-place device 17 is as follows: When it is necessary to pick up the foam base tray 22 and the foam top tray 23, the piston rod of the push plate cylinder 17-6 retracts, exposing the needle tip of the insert pin 17-2 below the push plate 17-1. Driven by the loading and unloading lateral movement device 11, the pick-and-place device 17 moves laterally to above the end of the base tray transmission line 25. Then, driven by the loading and unloading lifting device 18, the pick-and-place device 17 moves downward so that multiple sets of insert pins 17-2 are inserted into the foam base tray located at the end of the base tray transmission line 25. In step 22, the foam base tray 22 grabbed by the pallet-loading transverse device 11 and the pallet-loading lifting device 18 is then transferred to the packing station for pallet loading operation under the drive of the pallet-loading transverse device 11 and the pallet-loading lifting device 18. After the pallet-loading lifting device 18 drives the pallet-loading device 17 to descend and load the foam base tray 22 it has grabbed into the packaging box 15, the piston rod of the push plate cylinder 17-6 extends and drives the push plate 17-1 to move downward to push the foam base tray 22 on the insert pin 17-2 to disengage from the insert pin 17-2, thus realizing the pallet loading operation.

[0057] Then, the pallet-mounting horizontal movement device 11 and the pallet-mounting lifting device 18 work together to move the pallet-taking and placing device 17 to the top of the top pallet conveyor line 24. After the packaging bottle boxing operation is completed, the pallet-mounting horizontal movement device 11, the pallet-mounting lifting device 18 and the pallet-taking and placing device 17 work together to grab and transfer the foam top pallet 23 for boxing operation, and then cover the top of the packaging bottle with the foam top pallet 23. The grabbing, transferring and boxing process of the foam top pallet 23 is the same as the grabbing, transferring and boxing process of the foam bottom pallet 22.

[0058] To arrange the packaged soft bottles 100 transported by the chain conveyor line 27 into an M*N (where M is 6 and N is 5) matrix array, the array bottle sorting assembly in this embodiment includes a bottle sorting device 3, a transition platform device 6, and a bottle sorting transverse moving device 4. These three components work together to transfer the packaged soft bottles 100, arranged in rows of five, row by row, thus forming a 6*5 matrix array. The array bottle sorting assembly also includes a lifting support device 7 and a pushing device 2 mounted on the bottle sorting mounting frame 1. The lifting support device 7 can be used to support the packaged bottles arranged in a rectangular array, and the pushing device 2 can push the arrayed packaged bottles on the lifting support device 7 into the Y-axis adjusting device 10.

[0059] The bottle unscrambling device 3 includes multiple passageways 3-1 arranged side-by-side along the Y-axis for a predetermined number (five in this embodiment) of packaged soft bottles 100 transported on the chain conveyor line 27 to pass through. The array bottle unscrambling assembly also includes a transition platform device 6 located at the end of the chain conveyor line 27. The transition platform device 6 stops the packaged soft bottles 100 from exiting the passageways 3-1 and also functions as a platform to support the rows of packaged bottles transferred by the bottle unscrambling device 3. See further details. Figure 5 In this embodiment, the bottle sorting device 3 also includes a connected upright plate mounting base 3-3. Multiple sets of channel upright plates 3-2 are fixedly connected to the upright plate mounting base 3-3 and arranged laterally along the Y-axis. The passageway 3-1 is composed of two adjacent sets of channel upright plates 3-2.

[0060] like Figure 3 As shown, in this embodiment, the transition platform device 6 includes a transition platform 6-3 fixedly connected to the frame of the chain conveyor 27, which is disposed between the chain conveyor 27 and the lifting support device 7. A transmission baffle 6-2 is installed on the transition platform 6-3 to stop the packaged soft bottles 100 from passing through the passage 3-1 and to guide the transferred packaged soft bottles 100. It also includes a bottle-sorting guide plate 6-1 installed on the transition platform 6-3 opposite to the transmission baffle 6-2 to guide the transferred packaged soft bottles 100. Both the bottle-sorting guide plate 6-1 and the transmission baffle 6-2 have slotted holes, and the two are locked to the transition platform 6-3 by bolts passing through the slotted holes.

[0061] In this embodiment, the bottle-handling transverse device 4 can drive each through channel 3-1 to pass sequentially along the Y-axis above the transmission surface of the stop-supply chain plate transmission line 27, thereby transferring the packaging soft bottles 100 row by row in groups of 5, and arranging them into a 6*5 matrix array. Wherein, as Figure 4 As shown, the bottle-scraping transverse movement device 4 in this embodiment includes a bottle-scraping transverse movement seat 4-2 slidably connected to a Y-direction linear guide rail 5 via a slider, and a vertical plate mounting seat 3-3 connected to the bottle-scraping transverse movement seat 4-2. The bottle-scraping transverse movement device 4 also includes two sets of bottle-scraping pulley pairs 4-1 mounted on the bottle-scraping mounting frame 1, which are oppositely arranged to drive the bottle-scraping transverse movement seat 4-2 to move along the Y-direction linear guide rail 5. It also includes a transversely arranged bottle-scraping rotating shaft 4-3 for connecting the two sets of bottle-scraping pulley pairs 4-1 into one unit, and a bottle-scraping motor 4-4 for driving the bottle-scraping rotating shaft 4-3 to rotate. Further, in this embodiment, the bottle-scraping pulley pair 4-1 includes a driving pulley and a driven pulley rotatably connected at both ends of the bottle-scraping mounting frame 1. A closed belt is connected between the driving pulley and the driven pulley, and the bottle-scraping transverse movement seat 4-2 is connected to the belt via a connector.

[0062] The bottle-sorting lateral movement device 4 can drive the bottle-sorting device 3 to move stepwise along the Y-axis, thereby moving 5 packaged soft bottles 100 that have entered one of the passageways 3-1 of the bottle-sorting device 3 to the transition platform device 6, and moving the next passageway 3-1 above the transmission surface of the chain plate transmission line 27, so that the next group of 5 packaged soft bottles 100 can enter the passageway 3-1. The bottle-sorting lateral movement device 4 drives the bottle-sorting device 3 to move stepwise, thereby transferring multiple rows of packaged soft bottles 100 to the lifting support device 7. After the array arrangement of the packaged soft bottles 100 is completed, the lifting support device 7 drives the arrayed packaged soft bottles 100 to descend and detach from the bottle-sorting device 3, so that the bottle-sorting device 3 can be reversed and moved to the reset position under the drive of the bottle-sorting lateral movement device 4, in preparation for the next bottle-sorting operation.

[0063] like Figure 6 As shown, in this embodiment, the lifting support device 7 includes a support plate 7-3 for supporting the packaged soft bottles 100 transferred by the bottle unscrambling device 3. To limit the packaging soft bottles 100 and prevent them from tipping over due to mutual pushing, the lifting support device 7 also includes two adjustable-spaced support limiting plates 7-2 connected to the support plate 7-3, thereby pushing and limiting the packaging soft bottles 100 on the support plate 7-3. Under the squeezing action of the support limiting plates 7-2 and the squeezing action between multiple groups of packaging soft bottles 100, friction is generated between adjacent packaging soft bottles 100. This arrangement prevents the packaging bottle array on the lifting support device 7 from tipping over. Furthermore, each support limiting plate 7-2 has a slotted hole and is locked to the support plate 7-3 by bolts passing through the slotted hole.

[0064] The lifting support device 7 also includes a pallet lifting cylinder 7-1 that can move the support plate 7-3 up and down, used to move the support plate 7-3 between the receiving station and the discharging station. In addition, a mounting plate is installed on the bottle mounting rack 1, and the cylinder of the pallet lifting cylinder 7-1 is connected to the aforementioned mounting plate.

[0065] See further Figure 7 In this embodiment, the pushing device 2 includes a front mounting seat 2-2 and a rear mounting seat 2-5 fixedly connected to the bottle mounting frame 1 and arranged opposite to each other. A horizontally arranged pushing cylinder 2-4 is installed between the front mounting seat 2-2 and the rear mounting seat 2-5. The output end of the pushing cylinder 2-4 points towards the lifting support device 7 and is located between the two support limiting plates 7-2. The pushing device 2 also includes a pushing plate 2-1 installed at the extended end of the pushing cylinder 2-4, which is used to push the packaged soft bottles 100 on the support plate 7-3 located at the discharge station into the Y-axis adjusting device 10. In order to improve the stability of the lateral movement of the pushing plate 2-1, the pushing device 2 also includes multiple sets of pushing guide rods 2-3 installed on the pushing plate 2-1. Each pushing guide rod 2-3 is slidably connected to the front mounting seat 2-2 through a linear bearing.

[0066] Additionally, when the pushing device 2 pushes the arrayed soft-bottles 100 onto the Y-axis spacing adjustment device 10, the spacing limiting device 9 installed on the bottle mounting rack 1 can limit the soft-bottles 100, preventing them from tipping over during movement. See further details. Figure 3 The spacing limiting device 9 includes two sets of I-beams 9-2 fixed on the bottle mounting bracket 1. Each I-beam 9-2 extends along the X-axis. Two sets of opposing spacing limiting plates 9-1 span between the two I-beams 9-2. Each spacing limiting plate 9-1 has a strip hole at its end and is connected to the I-beam 9-2 by bolts passing through the strip holes.

[0067] Further participation Figure 8 and Figure 9 In this embodiment, the Y-axis adjusting device 10 includes an outer adjusting guide rail 10-6 extending along the Y-axis direction. Multiple sets of Y-axis adjusting units 10-1 are laterally arranged side-by-side on the outer adjusting guide rail 10-6 via sliders. Each Y-axis adjusting unit 10-1 includes a first adjusting support plate 10-1-1 and a second adjusting support plate 10-1-2, which are slidably connected to the outer adjusting guide rail 10-6 via sliders and arranged side-by-side. Both the first adjusting support plate 10-1-1 and the second adjusting support plate 10-1-2 are provided with bottle-holding stations 10-1-3 evenly distributed along the X-axis direction. In this embodiment, three sets of Y-axis adjusting units 10-1 are provided, with each adjusting support plate having five bottle-holding stations 10-1-3.

[0068] The Y-axis adjusting device 10 further includes a second connecting plate 10-3 installed between two adjacent sets of Y-axis adjusting units 10-1, and a first connecting plate 10-2 installed between a first adjusting support plate 10-1-1 and a second adjusting support plate 10-1-2. The first connecting plate 10-2 has two first strip-shaped holes extending along its length, and bolts are slidably inserted into each of the two first strip-shaped holes. The two bolts are respectively connected to the first adjusting support plate 10-1-1 and the second adjusting support plate 10-1-2 located within the same Y-axis adjusting unit 10-1. The second connecting plate 10-3 has two second strip-shaped holes extending along its length, and bolts are slidably inserted into each of the two second strip-shaped holes. The two bolts are respectively connected to adjacent first adjusting support plates 10-1-1 and second adjusting support plates 10-1-2 between two adjacent Y-axis adjusting units 10-1. In this embodiment, the length of the second strip-shaped hole is greater than the length of the first strip-shaped hole.

[0069] Furthermore, the Y-axis adjusting device 10 also includes an adjusting drive assembly 10-4, wherein the first connecting plate 10-2, the second connecting plate 10-3, and the adjusting drive assembly 10-4 work together to drive the adjacent first adjusting support plate 10-1-1 and second adjusting support plate 10-1-2 to switch between a close-fitting state and an extended state. Figure 8 As shown, in the actual working process, when the first adjustable tray 10-1-1 and the second adjustable tray 10-1-2 are in the unfolded state, the distance between two adjacent sets of Y-axis adjustable units 10-1 is m, and the distance between the first adjustable tray 10-1-1 and the second adjustable tray 10-1-2 in the same Y-axis adjustable unit 10-1 is n. The values ​​of m and n can be the same or different. The values ​​of m and n need to be set according to the position of the bearing hole on the foam base 22, so that the spacing distance of the arrayed soft bottles 100 in the Y-axis direction meets the packing requirements.

[0070] like Figure 8As shown, in this embodiment, two sets of pitch adjustment drive components 10-4 are provided, and the two sets of pitch adjustment drive components 10-4 are symmetrically arranged. The pitch adjustment drive assembly 10-4 includes a cylinder mounting plate 10-4-2 mounted on the bottle mounting bracket 1. A Y-axis pitch adjustment cylinder 10-4-1 is mounted on the cylinder mounting plate 10-4-2. The piston rod of the Y-axis pitch adjustment cylinder 10-4-1 extends in a direction parallel to the extension direction of the outer pitch adjustment guide rail 10-6. The cylinder of the Y-axis pitch adjustment cylinder 10-4-1 is connected to the cylinder mounting plate 10-4-2 and the second pitch adjustment support plate 10-1-2 (adjacent to the lifting support device 7) in the Y-axis pitch adjustment unit 10-1 located at one end via a pin. The piston rod of the Y-axis pitch adjustment cylinder 10-4-1 is connected to the first pitch adjustment support plate 10-1-1 (away from the lifting support device 7) in the Y-axis pitch adjustment unit 10-1 located at the other end via a fisheye joint and a pin. The piston rod of the Y-axis adjusting cylinder 10-4-1 extends, which can drive the adjacent first adjusting plate 10-1-1 and second adjusting plate 10-1-2 to the unfolded state, so as to achieve the purpose of adjusting the spacing between each row of packaging soft bottles in the Y-axis direction.

[0071] Given that the bottle body of the packaging soft bottle 100 is relatively soft, in order to prevent the packaging soft bottle from tipping over and affecting the packing operation when adjusting the spacing between each row of packaging soft bottles, the Y-axis spacing adjustment device 10 also includes an anti-tipping component 10-5 and a bottle stop block 10-7, which are used to limit the packaging soft bottle 100 in the bottle holding position 10-1-3 to prevent it from tipping over.

[0072] Among them, the bottle blocking block 10-7 is located on the first adjustable support plate 10-1-1 away from the lifting support device 7, so as to block and limit the row of packaging soft bottles 100 at the outermost end that are pushed into the Y-direction adjustable device 10, so as to prevent the packaging soft bottles from tipping over.

[0073] See further Figure 8 and Figure 10In this embodiment, the anti-tipping assembly 10-5 includes an anti-tipping lifting plate 10-5-2 located below the Y-axis adjusting unit 10-1. Further, the anti-tipping lifting plate 10-5-2 is located between two sets of outer adjusting guide rails 10-6 and can move freely up and down. Two sets of inner adjusting guide rails 10-5-4 extending along the Y-axis are fixedly connected to the anti-tipping lifting plate 10-5-2. The anti-tipping assembly 10-5 also includes multiple sets of parallel upright mounting plates 10-5-3 slidably connected to the inner adjusting guide rails 10-5-4 via sliders. Each set of upright mounting plates 10-5-3 corresponds one-to-one with multiple sets of adjusting trays. Multiple sets of upright units distributed along the X-axis and penetrating the corresponding adjusting tray are fixedly connected to each upright mounting plate 10-5-3. Each upright unit corresponds one-to-one with multiple bottle-holding stations 10-1-3 on the corresponding adjusting tray. Furthermore, in this embodiment, each upright unit is composed of four anti-tipping uprights 10-5-5. The four anti-tipping uprights 10-5-5 pass through the corresponding adjustable support plate and correspond one-to-one with the four corner positions of the bottle holding station 10-1-3. This can surround the packaging soft bottle 100 located on the bottle holding station 10-1-3 and prevent the packaging soft bottle 100 from shaking and tipping over when it moves.

[0074] The anti-tipping assembly 10-5 also includes an anti-tipping cylinder 10-5-1 for driving the anti-tipping lifting plate 10-5-2 to rise and fall. An mounting plate is installed on the bottle mounting bracket 1. The cylinder of the anti-tipping cylinder 10-5-1 is connected to the aforementioned mounting plate. The piston rod of the anti-tipping cylinder 10-5-1 is connected to the anti-tipping lifting plate 10-5-2. In order to improve the stability of the anti-tipping assembly 10-5, two sets of anti-tipping cylinders 10-5-1 are provided.

[0075] In actual operation, after the lifting support device 7 receives the packaged soft bottles 100 arranged in a rectangular array by the bottle sorting device 3, it lowers the aforementioned packaged soft bottle array to the discharge station. Then, the pushing device 2 is activated, pushing the entire packaged bottle array on the lifting support device 7 onto the Y-axis adjusting device 10. Figure 11As shown. At this time, the adjacent first adjusting tray 10-1-1 and second adjusting tray 10-1-2 in the Y-axis adjusting device 10 are in a close contact state, which facilitates the reception of packaged soft bottles distributed in a rectangular array, so that each packaged soft bottle is located on the corresponding bottle holding station 10-1-3. In addition, at this time, the top of the anti-tipping rod 10-5-5 in the anti-tipping assembly 10-5 is not higher than the supporting surface of the first adjusting tray 10-1-1 and the second adjusting tray 10-1-2, so as to prevent the anti-tipping rod 10-5-5 from blocking the packaged soft bottles from entering the Y-axis adjusting device 10. After the overall transfer of the array of packaged bottles is completed, the anti-tipping cylinder 10-5-1 in the anti-tipping assembly 10-5 is activated, driving the anti-tipping lifting plate 10-5-2 to move upward. This causes each anti-tipping upright rod 10-5-5 to move upward after passing through the corresponding adjustable support plate, thereby surrounding the packaged soft bottles 100 located on the bottle support station 10-1-3 at the four corners to prevent the packaged soft bottles 100 from tipping over during the transfer. Figure 10 As shown.

[0076] Since the adjacent bearing holes on the foam base 22 are arranged in an array, meaning that adjacent bearing holes have a certain distance between them in both the X and Y axes, after adjusting the spacing between two adjacent rows of soft bottles in the Y direction, it is also necessary to adjust the spacing between two adjacent columns of soft bottles 100 in the X direction. The X-axis spacing adjustment device 13 is a structure used to adjust the spacing between two adjacent columns of soft bottles 100 on the Y-axis spacing adjustment device 10.

[0077] See further Figure 12 and Figure 13 In this embodiment, the X-axis adjustment device 13 includes an X-axis guide rail assembly 13-5 extending along the X-axis direction; wherein, the X-axis guide rail assembly 13-5 is provided in two sets and is arranged side by side along the Y-axis direction; the X-axis guide rail assembly 13-5 includes two sets of guide rail mounting parts 13-5-1 connected to the packing assembly, and an X-axis adjustment guide rail 13-5-2 extending along the X-axis direction is fixed between the two sets of guide rail mounting parts 13-5-1.

[0078] Furthermore, a fixed-position middle adjustment unit 13-2 is provided on the X-direction adjustment guide rail 13-5-2 in the X-direction guide rail assembly 13-5. The assembly also includes multiple sets of front adjustment units 13-1 and multiple sets of rear adjustment units 13-3 with adjustable positions, which are provided on the X-direction adjustment guide rail 13-5-2 in the X-direction guide rail assembly 13-5. In this embodiment, two sets of front adjustment units 13-1 and two sets of rear adjustment units 13-3 are provided, and the two sets of front adjustment units 13-1 and the two sets of rear adjustment units 13-3 are respectively located on both sides of the middle adjustment unit 13-2.

[0079] In addition, a front connecting plate 13-9 is connected between two adjacent sets of front adjustment units 13-1, and a rear connecting plate 13-7 is connected between two adjacent sets of rear adjustment units 13-3. An intermediate connecting plate 13-6 is installed on the middle adjustment unit 13-2 to connect the front adjustment unit 13-1 and the rear adjustment unit 13-3 adjacent to the middle adjustment unit 13-2. That is, the middle adjustment unit 13-2 is connected to the middle part of the intermediate connecting plate 13-6, and the front adjustment unit 13-1 and the rear adjustment unit 13-3 adjacent to the middle adjustment unit 13-2 are respectively connected to the two ends of the intermediate connecting plate 13-6.

[0080] The X-axis adjusting device 13 also includes multiple sets of bottle grippers 13-10 distributed along the Y-axis direction and installed on each adjusting unit, for gripping the packaging soft bottle 100 on the Y-axis adjusting device 10 in the unfolded state.

[0081] See further Figure 13 The front adjustment unit 13-1 includes two sets of front adjustment seats 13-1-1 arranged side by side along the Y-axis. Each front adjustment seat 13-1-1 is slidably connected to the X-axis adjustment guide rail 13-5-2 via a slider. A front clamp seat 13-1-2 connecting the two sets of front adjustment seats 13-1-1 is installed between them. The middle adjustment unit 13-2 includes a middle fixing seat 13-2-3 passing through each X-axis adjustment guide rail 13-5-2. The middle fixing seat 13-2-3 is fixedly connected to the packing assembly. A middle adjustment seat 13-2-1 is fixedly connected to each middle fixing seat 13-2-3. A middle clamp seat 13-2-2 connecting the two middle adjustment seats 13-2-1 is installed between them. The rear adjustment unit 13-3 includes rear adjustment seats 13-3-1 arranged in parallel along the Y-axis direction. Each rear adjustment seat 13-3-1 is slidably connected to the X-axis adjustment guide rail 13-5-2 via a slider. A rear clamp seat 13-3-2 connecting the two sets of rear adjustment seats 13-3-1 is installed between them.

[0082] In this embodiment, multiple sets of bottle grippers 13-10 are respectively installed on corresponding gripper seats. In addition, 6 bottle grippers 13-10 are installed on each gripper seat. The 6 bottle grippers 13-10 are paired into a unit, and the distance between two adjacent units is p. The distance between two bottle grippers 13-10 in each unit is q. In this embodiment, p = m and q = n.

[0083] The bottle gripper 13-10 and the gripper base can be detachably connected, allowing for individual repair and replacement of a damaged bottle gripper 13-10, avoiding the need to replace the entire X-axis distance adjustment device 13 and reducing maintenance costs. Alternatively, the bottle gripper 13-10 and the gripper base can be fixedly connected. In this embodiment, the bottle gripper 13-10 uses a bottle gripping head from the prior art.

[0084] See further Figure 12 and Figure 13 The specific structure and connection method of the front connecting plate 13-9, the middle connecting plate 13-6, and the rear connecting plate 13-7 are as follows: the middle connecting plate 13-6 is fixedly connected to the middle adjusting seat 13-2-1 by bolts at the middle part; both ends of the middle connecting plate 13-6 are provided with strip-shaped holes extending along its length direction; bolts are slidably inserted into each strip-shaped hole and connected to the front adjusting seat 13-1-1 and the rear adjusting seat 13-3-1 adjacent to the middle adjusting seat 13-2-1 by bolts; a through hole is provided at one end of the rear connecting plate 13-7 and... A mounting screw is inserted into the hole at one end, and a bolt slides through the slotted hole extending along its length at the other end. Two adjacent rear adjustment seats 13-3-1 are connected to the rear connecting plate 13-7 by two bolts respectively. A through hole is opened at one end of the front connecting plate 13-9, and a mounting screw is inserted into the through hole. A slotted hole extending along its length is opened at the other end, and a bolt slides through the slotted hole. Two adjacent front adjustment seats 13-1-1 are connected to the front connecting plate 13-9 by two bolts respectively. In this embodiment, the lengths of the slotted holes on the front connecting plate 13-9, the intermediate connecting plate 13-6, and the rear connecting plate 13-7 are the same.

[0085] like Figure 12 As shown, the X-axis adjusting device 13 also includes a rear adjusting cylinder 13-4 and a front adjusting cylinder 13-8, which are used to drive adjacent adjusting units to switch between a close-to-each state and an extended state. In this embodiment, the rear adjusting cylinder 13-4 and the front adjusting cylinder 13-8 are symmetrically arranged about the center of the middle adjusting unit 13-2. The rear adjusting cylinder 13-4 and the front adjusting cylinder 13-8 work together to drive multiple sets of front adjusting units 13-1 and multiple sets of rear adjusting units 13-3 to extend outward or retract inward about the middle adjusting unit 13-2, thereby realizing the adjusting operation.

[0086] See further Figure 13 The cylinder barrel of the rear adjustable pitch cylinder 13-4 is connected to a set of front adjustable pitch seats 13-1-1 located at the edge via a pin. The piston rod of the rear adjustable pitch cylinder 13-4 is connected to a set of rear adjustable pitch seats 13-3-1 located at the edge via a spherical joint and a pin. The cylinder barrel of the front adjustable pitch cylinder 13-8 is connected to another set of rear adjustable pitch seats 13-3-1 located at the edge via a pin. The piston rod of the front adjustable pitch cylinder 13-8 is connected to another set of front adjustable pitch seats 13-1-1 located at the edge via a spherical joint and a pin.

[0087] In actual operation, after the Y-axis spacing adjustment device 10 adjusts the spacing between two adjacent rows of packaging soft bottles in the Y direction, the X-axis spacing adjustment device 13 moves laterally to the material-grabbing station under the action of the packing assembly. At this time, the middle spacing adjustment unit 13-2 is directly opposite the middle column of the packaging bottle array on the Y-axis spacing adjustment device 10, and the adjacent spacing adjustment units are in close proximity. Then, under the action of the packing assembly, the X-axis adjusting device 13 moves downward to a preset position so that the bottle gripper 13-10 can grip the corresponding packaged soft bottle 100. After the bottle gripper 13-10 completes the bottle gripping operation, the packing assembly drives the X-axis adjusting device 13 to move upward, causing the packaged soft bottle 100 to detach from the anti-tipping component 10-5. Then, the rear adjusting cylinder 13-4 and the front adjusting cylinder 13-8 are activated simultaneously, causing multiple sets of front adjusting units 13-1 and multiple sets of rear adjusting units 13-3 to unfold outward about the middle adjusting unit 13-2, thereby completing the process of adjusting the spacing between adjacent rows of packaged bottles in the X-axis direction. After completing the above-mentioned adjusting operation, the packing assembly drives the X-axis adjusting device 13 to move laterally and longitudinally, thereby completing the packing operation of the packaged soft bottle, that is, filling the packaged bottle gripped by the X-axis adjusting device 13 into the bearing hole of the foam base tray 22 inside the packaging box 15.

[0088] like Figure 1 As shown, in this embodiment, the packing assembly includes a packing lifting device 14 connected to the X-axis adjusting device 13, used to drive the X-axis adjusting device 13 to move up and down; it also includes a packing traversing device 12, used to drive the X-axis adjusting device 13 and the packing lifting device 14 to move along the X-axis direction between directly above the Y-axis adjusting device 10 and directly above the packing support device 16. The packing traversing device 12 is slidably connected to the X-axis linear guide rail 19 via a slider.

[0089] See further Figure 14 In this embodiment, the packing transverse movement device 12 includes a packing transverse movement seat 12-2 slidably connected to the X-direction linear guide rail 19 via a slider, and also includes a packing pulley pair 12-3 and a packing transverse movement motor 12-1 mounted on the transverse movement bracket 21, for driving the packing transverse movement seat 12-2 to move along the X-direction linear guide rail 19; the packing pulley pair 12-3 includes a driving pulley and a driven pulley rotatably connected to both ends of the transverse movement bracket 21, and a closed belt is connected between the driving pulley and the driven pulley for transmission; the packing transverse movement seat 12-2 is connected to the belt; and the packing transverse movement motor 12-1 is used to drive the driving pulley to rotate.

[0090] The packing lifting device 14 includes a packing lifting electric cylinder 14-3 connected to the packing transverse seat 12-2 and with its extended end facing downward. A packing lifting seat 14-1 is installed at the extended end of the packing lifting electric cylinder 14-3. The device also includes a longitudinally arranged packing guide rod 14-2 installed on the packing lifting seat 14-1. The packing guide rod 14-2 is slidably connected to the packing transverse seat 12-2 via a linear bearing.

[0091] Driven by the packing transverse movement device 12 and the packing lifting device 14, the X-axis distance adjustment device 13 can complete bottle grabbing, transfer and packing operations with precise operation and a high degree of automation.

[0092] In the actual working process, the packaging soft bottles 100 are transported through the chain plate conveyor line 27, and a preset number (5 in this embodiment) of packaging soft bottles 100 are transported into the passageway 3-1. In order to ensure that the preset number of packaging soft bottles 100 can enter the passageway 3-1 accurately, this embodiment also includes a centering limit device 8 installed on the chain plate conveyor line 27 and located upstream of the bottle unloading device 3.

[0093] See further Figure 3 In this embodiment, the centering and limiting device 8 includes a mounting base fixedly connected to the bottle mounting frame 1. Two sets of centering cylinders 8-2 are fixedly connected to the mounting base. The two sets of centering cylinders 8-2 are arranged opposite to each other and symmetrically about the transmission surface of the chain conveyor line 27. A centering mounting seat 8-3 is installed at the protruding end of each centering cylinder 8-2. The device also includes centering components 8-1 installed on the opposite surfaces of each centering mounting seat 8-3 to center and limit the soft packaging bottles 100 transported on the chain conveyor line 27.

[0094] Work process:

[0095] (1) Box support operation: The packaging box 15 is transported to the packing station through the box body transmission line 26. At this time, the four box support plate structures 16-5 in the box support device 16 are in a state of tilting at the lower end under the drive of their respective box support cylinders 16-4, so as to avoid affecting the movement of the packaging box 15. After the packaging box 15 runs to the packing station, the lower ends of the four box support plate structures 16-5 are pressed down under the drive of their respective box support cylinders 16-4, thereby opening the box pages of the packaging box 15 from the inside to the outside, so as to facilitate the material to enter the box. Before the operation, the height of the mounting optical axis 16-3, the distance between the two mounting square tubes 16-7 and the distance between the two tube mounting components 16-6 on the same mounting square tube 16-7 can be adjusted according to the size of the packaging box 15, so as to adjust the overall height of the four box support plate structures 16-5 and the distance between the two adjacent box support plate structures 16-5, so as to meet the box support requirements of the packaging box 15.

[0096] (2) Loading the base tray: The foam base tray 22 is transported to the packing station at the end via the base tray conveyor line 25. Then, the loading lateral movement device 11 and the loading lifting device 18 work together to move the pick-and-place device 17 to the gripping station above the end of the base tray conveyor line 25. The pick-and-place device 17 starts to grip the foam base tray 22. The working principle of the pick-and-place device 17 is as described above and will not be repeated here. After the pick-and-place device 17 completes the gripping operation, the loading lateral movement device 11 and the loading lifting device 18 work together again to move the pick-and-place device 17 and complete the transfer and loading of the foam base tray 22 into the box.

[0097] (3) Bottle handling and packing operations:

[0098] (i) Array bottle arrangement process: The bottle traversing device 4 drives the bottle traversing device 3 to move step by step, thereby transferring the packaged soft bottles conveyed by the chain plate transmission line 27 to the lifting support device 7 row by row, thereby arranging the packaged soft bottles into a rectangular array. After the array arrangement of the packaged soft bottles 100 is completed, the lifting support device 7 drives the packaged soft bottles 100 distributed in the array to descend to the discharge station to get away from the bottle traversing device 3, so that the bottle traversing device 3 can be moved in the opposite direction to the reset under the drive of the bottle traversing device 4, in preparation for the next bottle traversing operation.

[0099] (ii) Y-axis adjustment process: Then the pushing device 2 is activated, pushing the entire array of packaged bottles on the lifting support device 7 onto the Y-axis adjustment device 10. At this time, the adjacent first adjustment plate 10-1-1 and second adjustment plate 10-1-2 in the Y-axis adjustment device 10 are in a close contact state. After the overall transfer of the array of packaged bottles is completed, the anti-tipping cylinder 10-5-1 in the anti-tipping assembly 10-5 is activated, driving the anti-tipping lifting plate 10-5-2 to move upward, thereby causing the four corners of each anti-tipping upright rod 10-5-5 to surround the packaged soft bottle 100 located on the bottle support station 10-1-3, such as Figure 10 As shown, to prevent the packaging soft bottle 100 from tipping over during the adjustment process; then the piston rod of the Y-axis adjustment cylinder 10-4-1 extends, driving the adjacent first adjustment tray 10-1-1 and second adjustment tray 10-1-2 to move to the unfolded state, so as to achieve the purpose of adjusting the spacing between each row of packaging soft bottles in the Y-axis direction.

[0100] (iii) X-axis spacing adjustment process: Under the action of the packing assembly, the X-axis spacing adjustment device 13 moves laterally to the material-grabbing station. At this time, the middle spacing adjustment unit 13-2 is directly opposite the middle column of the packaging bottle array on the Y-axis spacing adjustment device 10, and the adjacent spacing adjustment units are in close proximity. Then, under the action of the packing assembly, the X-axis spacing adjustment device 13 moves downward to the preset position so that the bottle-grabbing clamp 13-10 can grab the corresponding packaging soft bottle 100. After the bottle-grabbing clamp 13-10 completes the bottle-grabbing operation, the packing assembly drives the X-axis spacing adjustment device 13 to move upward. After the packaging soft bottle 100 is removed from the anti-tipping component 10-5, the rear spacing adjustment cylinder 13-4 and the front spacing adjustment cylinder 13-8 are started at the same time, driving multiple sets of front spacing adjustment units 13-1 and multiple sets of rear spacing adjustment units 13-3 to unfold outward about the middle spacing adjustment unit 13-2, thereby completing the process of adjusting the spacing between two adjacent columns of packaging bottles in the X-axis direction.

[0101] (iv) Packing and traying process of soft bottles: After completing the above-mentioned X and Y direction adjustment operations, the packing lateral movement device 12 and the packing lifting device 14 drive the X direction adjustment device 13 to move, thereby driving the packaged soft bottles to the packing station. Then the packing lifting device 14 drives the X direction adjustment device 13 to descend until the packaged soft bottles are placed into the bearing holes of the foam base tray 22 inside the packaging box 15.

[0102] (4) Top tray loading operation: The foam top tray 23 is transported to the end packing station via the top tray conveyor line 24. Then, the loading lateral movement device 11 and the loading lifting device 18 work together to move the pick-and-place device 17 to the gripping station above the end of the top tray conveyor line 24. The pick-and-place device 17 starts to grip the foam top tray 23. The working principle of the pick-and-place device 17 is as described above and will not be repeated here. After the pick-and-place device 17 completes the gripping operation, the loading lateral movement device 11 and the loading lifting device 18 work together again to move the pick-and-place device 17, complete the transfer of the foam top tray 23 and the loading into the box, and complete the boxing and palletizing operation of the first layer of packaged soft bottles 100, so as to facilitate the subsequent second layer of boxing operation.

[0103] (5) Repeat the bottom tray loading process, bottle sorting and boxing process and top tray loading process to finally achieve multi-layer boxing operation of packaging bottles.
