[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] The stacking assembly of this utility model embodiment is used to stack bottles (with film wrapped in rows) after they have been wrapped. It is equipped with a transfer device for placing the bottles and a boxing device for boxing the stacked bottles.

[0023] Reference Figure 1 and Figure 2 As shown, a stacking assembly according to an embodiment of the present invention includes: a slide table 7-20, a lifting table 7-18, a aligning assembly, an opening and closing mechanism, and an ejection mechanism.

[0024] The slide 7-20 is configured to move back and forth to facilitate movement to the corresponding bottle placement position.

[0025] The lifting platform 7-18 is mounted on the slide 7-20 and is used to support the bottle.

[0026] The aligning assembly is located on the slide table 7-20. The aligning assembly includes a front clamping mechanism, a rear clamping mechanism, and a side clamping mechanism. The front clamping mechanism and the rear clamping mechanism are arranged opposite each other and can move back and forth relative to the lifting platform 7-18. The front clamping mechanism and the rear clamping mechanism are used to cooperate with the front and rear aligning to support the bottles on the lifting platform 7-18. Two side clamping mechanisms are arranged opposite each other on the left and right. Both side clamping mechanisms can move left and right relative to the lifting platform 7-18. The two side clamping mechanisms are used to cooperate with the left and right aligning to support the bottles on the lifting platform 7-18. Obviously, the aligning assembly has an initial position. When it is in the initial position, it avoids the lifting path of the lifting platform 7-18.

[0027] The opening and closing mechanism is located on the slide table 7-20. The opening and closing mechanism is used to control the opening or closing of the front clamping mechanism. When the front clamping mechanism is open, the front clamping mechanism and the lifting table 7-18 are offset to the left and right. When the front clamping mechanism is closed, the front clamping mechanism can cooperate with the rear clamping mechanism to align and support the bottles on the lifting table 7-18. By setting the opening and closing mechanism, the front clamping mechanism can be opened after stacking is completed, so as to facilitate the unloading of the stacked bottles.

[0028] The ejection mechanism is located on the slide table 7-20. When the front clamping mechanism is open and the lifting table 7-18 is located under the aligning assembly, the ejection mechanism pushes the bottle supported on the lifting table 7-18 forward onto the lifting table 7-18. By setting the ejection mechanism, after stacking is completed, the front clamping mechanism can be opened, and then the ejection mechanism can be used to automatically push the bottle on the lifting table 7-18 out and unload it to the next station.

[0029] In this embodiment, the stacking assembly allows for the placement of a row of wrapped bottles on the lifting platform 7-18 using a transfer device. Each row of bottles is aligned using an alignment component. After one layer is filled, the lifting platform 7-18 can be lowered to place the next layer of bottles on top, thus stacking the bottles to the specified number of layers and rows and aligning their positions during the stacking process. After stacking, a boxing device can be used to cover all the bottles with a packaging box. Then, the front clamping mechanism is opened, and the ejection mechanism pushes out the packaging box and the bottles inside, achieving automatic unloading. By adopting the above structural design, automatic bottle stacking can be achieved, significantly improving production efficiency.

[0030] It should be noted that in this embodiment, multiple rows of bottles are arranged one after the other.

[0031] Reference Figure 1As shown, in some embodiments of this utility model, the stacking assembly further includes a frame, with the slide 7-20 movably connected to the frame. A fifth driving component 7-19 is provided on the frame to drive the slide 7-20 to move back and forth. It is understood that the fifth driving component 7-19 can adopt various structural forms, such as a servo motor plus a synchronous pulley and a synchronous belt. This is a conventional technical means, and therefore will not be described in detail here.

[0032] Reference Figure 1 As shown, in some embodiments of this utility model, the lifting platform 7-18 can be vertically slidably mounted on the slide 7-20 via a guide rod. A sixth driving component 7-17 is also connected between the slide 7-20 and the lifting platform 7-18 to drive the lifting platform 7-18 to rise and fall. The sixth driving component 7-17 can be a cylinder, a hydraulic cylinder, etc., and this embodiment does not make specific limitations.

[0033] Reference Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the clamping assembly further includes a first driving member 7-1, a fourth driving member 7-15, and a seventh driving member 7-11. The first driving member 7-1 is used to drive the front clamping mechanism to move back and forth, the fourth driving member 7-15 is used to drive the rear clamping mechanism to move back and forth, and the seventh driving member 7-11 is used to drive the side clamping mechanism to move left and right. Each of the two side clamping mechanisms is provided with one first driving member 7-1. The first driving member 7-1, the fourth driving member 7-15, and the seventh driving member 7-11 can all be cylinders, hydraulic cylinders, or other power structures capable of achieving the driving requirements.

[0034] Reference Figure 1 and Figure 3 As shown, in some embodiments of this utility model, the front clamping mechanism includes a swing seat 7-2, a swing rod 7-4, and a limiting pin 7-21. The swing seat 7-2 is connected to the first driving member 7-1 and can move back and forth under the drive of the first driving member 7-1; the swing rod 7-4 is rotatably connected to the swing seat 7-2 via a rotating shaft 7-3 and a bearing around a first axis, the first axis being the central axis of the rotating shaft 7-3 and extending back and forth. By rotating the swing rod 7-4, the front clamping mechanism can be opened and closed, making operation simple; the limiting pin 7-21 is provided on the swing seat 7-2, and the limiting pin 7-21 is used to abut against the swing rod 7-4 when the front clamping mechanism is closed, so that the swing rod 7-4 remains horizontal (distributed left and right), thereby keeping the front clamping mechanism closed, so as to facilitate the bottle alignment operation using the front clamping mechanism. In this embodiment, the rotating shaft 7-3 and the limiting pin 7-21 are arranged parallel to each other.

[0035] Reference Figure 1 and Figure 3As shown, in some embodiments of this utility model, the front clamping mechanism further includes a front nylon plate 7-10 and a compression spring 7-9. The front nylon plate 7-10 is slidably connected to the rear side of the swing arm 7-4 via a spring guide post 7-8. The front nylon plate 7-10 is used to contact the bottle to avoid damaging the bottle. The compression spring 7-9 is sleeved on the spring guide post 7-8 and located between the front nylon plate 7-10 and the swing arm 7-4. The compression spring 7-9 is used to apply a rearward elastic force to the front nylon plate 7-10. Thus, when the front clamping mechanism is used to align the bottle, the compression spring 7-9 can provide elastic buffering, ensuring sufficient contact force while avoiding damage to the bottle.

[0036] Reference Figure 1 and Figure 3 As shown, in some embodiments of this utility model, a pin 7-6 is provided on the rocker arm 7-4, and the opening and closing mechanism includes a second driving member 7-7 and a slot plate 7-5. The second driving member 7-7 is mounted on the slide table 7-20. The slot plate 7-5 is connected to the second driving member 7-7 and can move up and down between a first position and a second position under the drive of the second driving member 7-7. The first position is higher than the second position. The slot plate 7-5 is located on the front side of the lifting platform 7-18. The slot plate 7-5 is provided with a slot that extends horizontally and passes through from front to back. When the slot plate 7-5 is in the first position, the front clamping mechanism can move forward to insert the pin 7-6 into the slot. During the process of the pin 7-6 being inserted into the slot and the slot plate 7-5 moving from the first position to the second position, the swing rod 7-4 can be rotated through the cooperation between the slot and the pin 7-6 to open the front clamping mechanism. The structure is simple and practical. In this embodiment, the advantage of the above structure is that the opening and closing mechanism does not need to move back and forth with the front clamping mechanism, which can reduce the load on the first driving member 7-1 that drives the front clamping mechanism to move back and forth. It should be noted that under normal circumstances, the slot plate 7-5 is kept in the first position. Only when unloading is completed after stacking is the slot plate 7-5 adjusted from the first position to the second position. After unloading is completed, the slot plate 7-5 needs to be reset to the first position.

[0037] It is conceivable that the second driving component 7-7 can be a cylinder, hydraulic cylinder, telescopic motor, etc., depending on the driving requirements. This embodiment does not make specific limitations on this.

[0038] Reference Figure 1 As shown, in some embodiments of this utility model, the aligning assembly includes two front clamping mechanisms arranged opposite each other. By providing two front clamping mechanisms, the length of a single swing arm 7-4 can be reduced, the distance from the free end of the swing arm 7-4 to its rotation axis can be shortened, the risk of deformation can be reduced, and the structural stability can be improved. It also reduces the occupation of vertical space. Furthermore, it should be noted that during the opening process of the two front clamping mechanisms, the rotation directions of their swing arms 7-4 are opposite.

[0039] Reference Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the ejection mechanism includes a third driving member 7-13 and a rear support 7-14. The third driving member 7-13 is disposed on the slide table 7-20; the rear support 7-14 is connected to the third driving member 7-13 and can move back and forth under the drive of the third driving member 7-13; wherein, the rear clamping mechanism is movably connected to the rear support 7-14 through a guide structure, and the fourth driving member 7-15 is disposed on the rear support 7-14 and connected to the rear clamping mechanism, for driving the rear clamping mechanism to move back and forth relative to the rear support 7-14; in this embodiment, after stacking is completed, the rear support 7-14 can be driven forward by the third driving member 7-13 to eject the bottles on the lifting platform 7-18 forward through the rear clamping mechanism connected to the rear support 7-14.

[0040] It is conceivable that the third drive component 7-13 could be a rodless cylinder. Of course, other power structures could also be used, depending on the drive requirements.

[0041] Reference Figure 1 As shown, in some embodiments of this utility model, the aligning components are arranged in two vertically spaced layers, one in each layer. The upper aligning component is used to align the bottles row by row, while the lower aligning component is used to align the entire layer of bottles, serving as an auxiliary positioning function.

[0042] Based on the above embodiments, it can be understood that the first driving component 7-1 of the lower alignment assembly can adopt a power structure with a short driving stroke to reduce space occupation, such as a cylinder, hydraulic cylinder, telescopic motor, etc.; while the first driving component 7-1 of the upper alignment assembly can adopt a power structure with a long driving stroke. For example, the first driving component 7-1 of the upper alignment assembly can include two modules, left and right. The swing seats 7-2 of the two front clamping mechanisms of the upper layer are respectively installed on the two modules. The servo motor drives the modules on both sides to move back and forth simultaneously through the cooperation structure of synchronous pulley and synchronous belt, thereby realizing the simultaneous back and forth movement of the two front clamping mechanisms of the upper layer, realizing the following limit and alignment operation when placing each row of bottles. The above-mentioned structural form of the first driving component 7-1 is a conventional technical means, so it will not be described in detail here. Of course, the first driving component 7-1 of the upper alignment assembly can also adopt other structural forms to meet the driving requirements, such as a combination structure of motor screw mechanism plus synchronous belt plus synchronous pulley, to realize the simultaneous back and forth movement of the two front clamping mechanisms of the upper layer.

[0043] Based on the above embodiments, it can be understood that when the alignment components are arranged in two vertically spaced layers, the rear clamping mechanism of the upper and lower alignment components and the fourth driving component 7-15 are both arranged on the rear bracket 7-14.

[0044] Reference Figure 1 and Figure 2As shown, in some embodiments of this utility model, the rear clamping mechanism includes a rear nylon plate 7-16 for contacting the bottle. The rear nylon plate 7-16 is slidably connected to the rear bracket 7-14 via a guide structure. The rear nylon plate 7-16 is connected to the fourth driving member 7-15. The side clamping mechanism includes a side nylon plate 7-12 for contacting the bottle. The side nylon plate 7-12 is connected to the output end of the seventh driving member 7-11. With the above structural arrangement, damage to the bottle can be prevented when performing the bottle alignment operation.

[0045] The stacking method for the above stacking components includes the following steps: Step 1: Move the slide 7-20 back and forth to the corresponding bottle placement position, and then drive the lifting platform 7-18 to rise between the two layers of the aligning components via the sixth drive component 7-17.

[0046] Step 2: Place thick cardboard on the lifting platform 7-18, and then stack the first layer of bottles on the cardboard. Placing the cardboard can be done by automated equipment.

[0047] The first layer of bottles is stacked by: controlling the upper rear clamping mechanism to move forward a preset distance, the two upper side clamping mechanisms to move towards each other a preset distance, and the upper front clamping mechanism to move backward a preset distance, so as to leave space on the upper side of the rear end of the lifting platform 7-18 that can accommodate at least one row of bottles; then using a transfer device to send the entire row of bottles onto the thick cardboard of the lifting platform 7-18, so that this row of bottles is located within the space enclosed by the upper rear clamping mechanism, front clamping mechanism, and side clamping mechanism; then moving the upper front clamping mechanism backward, so that the entire row of bottles is pressed against the rear nylon plate of the upper rear clamping mechanism by the compression spring 7-9 and the front nylon plate 7-10. On step 7-16, the first row of bottles is placed and aligned. Then, the upper front clamping mechanism is moved forward by a preset distance to leave space between the upper front clamping mechanism and the first row of bottles, which can accommodate at least one row of bottles. Then, the transfer device is used to send the new row of bottles to the cardboard on the lifting platform 7-18. The upper front clamping mechanism is moved backward so that the compression spring 7-9 and the front nylon plate 7-10 can be used to press the new row of bottles against the first row of bottles, thus completing the placement and alignment of the second row of bottles. Then, the above steps are repeated to complete the placement and alignment of the Nth row of bottles. Here, N is an integer, and its value is selected according to production needs.

[0048] Step 3: Place the first partition on the bottles of the first layer, reset the upper layer alignment component, and then move the lifting platform 7-18 down to reset so that the first partition is located between the two layers of alignment components; then drive the lower layer rear clamping mechanism, two side clamping mechanisms, and front clamping mechanism toward the bottles of the first layer through the corresponding driving components to align the bottles of the first layer again and achieve precise positioning.

[0049] Step 4: Following the steps for stacking the first layer of bottles, stack the second layer of bottles on the first partition. Stacking the second layer of bottles is also done using the alignment component on the upper layer. The four sides of the second layer of bottles should be aligned with the four sides of the first layer of bottles.

[0050] Step 5: Place the second partition on the second layer of bottles; then use the box-making device to place the packaging box on the two layers of bottles from top to bottom; after the box-making is completed, open the front clamping mechanism of the upper and lower layers, and use the pushing mechanism to push the packaging box and the bottles forward onto the lifting platform 7-18.

[0051] The specific operation of step five is as follows: When using the box-sleeving device to put the packaging box down, first put it up to half the height of the second layer of bottles, and then reset the upper-layer alignment component to avoid the packaging box. During the reset process, the pin 7-6 of the front clamping mechanism of the upper-layer alignment component is inserted into the slot of the corresponding slot plate 7-5. Then continue to put the packaging box down. When it is put up to half the height of the first layer of bottles, reset the lower-layer alignment component to avoid the packaging box. During the reset process, the pin 7-6 of the front clamping mechanism of the lower-layer alignment component is inserted into the slot of the corresponding slot plate 7-5. The box-sleeving device puts the packaging box on the bottom and then leaves.

[0052] After the box is set up, the upper and lower layers are driven by the second drive unit 7-7 to move the corresponding slot plates 7-5 downwards to open the front clamping mechanisms of the upper and lower layers respectively. Then, the rear support 7-14 is driven forward by the third drive unit 7-13 to move the rear clamping mechanisms of the upper and lower layers forward together, so as to push the box along with the bottles inside it forward to the lifting platform 7-18 to the next station, thus completing all the operations.
