In the present application, a clamping rod serves as the vertex of a triangular fixed packaging structure, and two reset rods serve as bottom points, and a stable triangular fixed structure is formed between the three. The triangular fixed structure can evenly distribute the pressure applied thereto to each fulcrum, thereby avoiding structural damage or failure caused by excessive force on a single point. At the same time, even if a problem occurs at a certain fixed point, other fixed points can still maintain the stability of the carton, thereby avoiding the problem of "one point broken, all scattered" in traditional packaging methods, thereby greatly improving the packaging quality and the transportation stability of the carton.

Description

Technical Field

[0001] The present invention relates to the technical field of packaging devices, and more specifically, to an automatic stacking and packaging device for cold drink carton packaging. Background Art

[0002] Cold drink cartons are packaging cartons used for shipping and storing cold drink products. They are mostly made of high-strength, pressure-resistant corrugated cardboard. This material provides good cushioning properties and can effectively protect the cold drink products inside from external impacts. And because cold drinks will produce condensation water under refrigerated or frozen conditions, cold drink cartons are generally treated with special waterproofing, or use lining materials with moisture-proof function to ensure that the carton will not become soft or damaged due to moisture.

[0003] Cold drink products are usually fragile or sensitive (such as glass bottled drinks, frozen foods, etc.). If they collapse or collide during transportation, it may cause bottles to break, liquids to leak or product quality to be damaged. Therefore, after the automatic palletizing of the palletizer is completed, the fully loaded pallet is transferred to the packaging area for packaging. It is necessary to wrap multiple layers of stretch film (also called stretch film) around the outside of the entire stack of cartons and use strapping to wrap and reinforce them multiple times. However, this packaging method still has certain defects: 1. Although the stretch film can provide wrapping and fixing effects to a certain extent, it mainly relies on the tension of the film to maintain the stability of the carton. For cold drink cartons with heavy weight or irregular shapes, the tension of the stretch film may not be enough to prevent relative movement between cartons. Although the strapping tape can add additional fixing effects, it has fewer fixing points, usually only concentrated on the outer edge of the pallet and the carton. This fixing method cannot evenly distribute the pressure, which can easily lead to excessive force on some parts, while other parts lack sufficient support, increasing the risk of carton collapse or collision, resulting in low stability of the carton during transportation.

[0004] 2. Since there are fewer fixing points for the strapping tape and each strapping tape is interdependent, once a section of the strapping tape breaks, the load on other strapping tapes will increase, and the stability of the entire packaging structure will be seriously affected, causing the carton to loosen or even collapse.

[0005] 3. Although the combination of stretch film and packing tape can reduce the friction between cartons to a certain extent, they cannot effectively absorb the impact energy during transportation. When the vehicle encounters bumps or sudden brakes during driving, violent collisions may occur between cartons, causing damage to the internal cold drink products and leakage. Summary of the invention

[0006] The present invention provides an automatic stacking and packaging device for cold drink carton packaging, which solves the technical problem in the prior art that the strapping belt has few fixing points and is only concentrated at the outer edge of the pallet and the carton, resulting in low stability of the carton during transportation.

[0007] The present invention provides an automatic stacking and packaging device for cold drink carton packaging, comprising a pallet for carrying cartons and two mounting plates symmetrically installed on the top of the pallet, a pressing and locking unit is arranged between the two mounting plates, the pressing and locking unit comprises a pressing component and a control component that controls the pressing component to press the carton, a triangular locking unit is arranged between the pallet and the mounting plates, the triangular locking unit comprises two triangular fixing components symmetrically arranged on the left and right, a tightening component for tightening the triangular fixing components and two pressing components symmetrically arranged on the left and right, a side block locking unit is arranged between the two triangular fixing components, the side block locking unit comprises two side block components symmetrically arranged front and back and a locking component for reinforcing the side block components.

[0008] The clamping assembly includes a pad placed on the top of the top carton and a rotating rod rotatably installed between two mounting plates and passing through the two mounting plates. Control circular plates are commonly installed at both ends of the rotating rod. The tensioning assembly includes two mounting cylinders fixedly installed between the left and right inner walls of the pallet and symmetrically front and back, and a tensioning rod slidably connected to the mounting cylinders.

[0009] The triangular fixing assembly includes a clamping rod rotatably installed on the side of the control circular plate away from the rotating rod and a hinge sleeve clamped on the outside of the clamping rod. Two front and rear symmetrical locking rods are hinged on the hinge sleeve. The two locking rods are respectively hooked with the front and rear tensioning rods to form a triangular fixation.

[0010] Furthermore, a plurality of reinforcing plates are arranged between the top inner wall and the bottom inner wall of the tray, and the mounting tube is fixedly passed through the plurality of reinforcing plates. The tensioning assembly also includes two fixed tubes fixedly installed on the bottom inner wall of the tray and symmetrically front and back. A baffle is fixedly installed on the bottom inner wall of the fixed tube through reset spring 2, and a reset plate is fixedly installed on the top of the baffle through a round rod. The two reset plates are fixedly connected to the front and rear tensioning rods respectively, and the length of the round rod is greater than the height of the fixed tube, so that the baffle is always kept in the fixed tube to prevent gravel and dust from entering reset spring 2 through the mounting tube.

[0011] Furthermore, two groups of limit cylinders are fixedly installed on the inner wall of the bottom of the tray, and a single group of limit cylinders is symmetrically arranged on the left and right. Two limit rods are fixedly installed on the bottom of the two tensioning rods, and the limit rods at the bottom of the two tensioning rods are slidably connected to the two groups of limit cylinders on the front and rear respectively.

[0012] Furthermore, the control component includes an arc-shaped control groove opened on the mounting plate, a slide groove is opened on the control circular plate, a pressure rod is slidably connected in the left and right slide grooves, the pressure rod is slidably connected in the control groove, and one end of the pressure rod close to the control circular plate is slidably connected in the slide groove. The rotation of the control circular plate will drive the pressure rod to slide along the control groove and move along the slide groove to the side away from the center of the control circular plate, so that the pressure rod presses the pad.

[0013] Furthermore, the triangular fixing assembly also includes an annular hook groove provided on the tensioning rod, the locking rod is hook-shaped at one end close to the tensioning rod and is hooked in the annular hook groove, and two installation cavities symmetrical up and down are provided in the hinge sleeve, and a reset spring 1 is fixedly installed on the inner wall of the two installation cavities on one side, and a buckle is fixedly installed on one end close to the two reset springs 1, and the side of the buckle away from the reset spring 1 is triangular-shaped, and a clamping groove engaged with the buckle is provided on the outer side of the clamping rod.

[0014] Furthermore, the pressing assembly includes a guide groove provided in the mounting plate and a pressing plate slidably connected in the guide groove. The bottom of the pressing plate slides through the inner wall of the top of the tray and is fixedly connected to the front and rear tensioning rods through a connecting rod.

[0015] Furthermore, the top of the guide groove is connected to the bottom of the control groove, and a triangular protrusion is provided on the top of the lower pressure plate. When the pressure rod slides along the control groove, it will squeeze the triangular protrusion and drive the lower pressure plate to move downward, so that the tensioning rod moves downward, and drives the triangular fixing assembly to tighten and lock.

[0016] Furthermore, the side block assembly includes a connecting sleeve fixedly installed on the outside of the locking rod, the connecting sleeve is located above the hook-shaped section of the locking rod, and side block rods are rotatably installed on the adjacent sides of the left and right connecting sleeves. The top end of the side block rod is hook-shaped, and two side hook grooves are provided on the front and rear sides of the pad. The four side hook grooves are distributed in a square shape, and the top ends of the two rear side block rods are hooked with the two rear side hook grooves, and the top ends of the two front side block rods are hooked with the two front side hook grooves.

[0017] Furthermore, a socket is fixedly installed in the middle of the side guard rod, and a plug is inserted between the two sockets opposite to each other on the left and right sides, and the plug is fixed to the socket on the right side through a nut.

[0018] Furthermore, a slot that passes through from top to bottom is provided in the middle of the front and rear bolts, and the latch assembly includes a U-shaped latch rod, the two vertical sections of the U-shaped latch rod are respectively inserted into the two slots, and the bottom ends of the two vertical sections of the U-shaped latch rod are respectively provided with external threads, and two threaded sleeves that are symmetrical front and back are rotatably installed on the top of the tray, and the two threaded sleeves are respectively threadedly connected to the two vertical sections of the U-shaped latch rod.

[0019] The beneficial effects of the present invention are: 1. In the present application, the pressure rod serves as the vertex of the triangular fixed packaging structure, and the two reset rods serve as the bottom points, and a stable triangular fixed structure is formed between the three. The triangular fixed structure can evenly distribute the pressure applied thereon to each fulcrum, thereby avoiding structural damage or failure caused by excessive force on a single point. At the same time, even if a problem occurs at a certain fixed point, the other fixed points can still maintain the stability of the carton, thereby avoiding the problem of "one point broken, all scattered" in the traditional packaging method, thereby greatly improving the packaging quality and the transportation stability of the carton.

[0020] 2. In the present application, a stable integrated side barrier fixing structure is formed between the side barrier rod, the bolt and the U-shaped locking rod. The integrated side barrier fixing structure not only enhances the fixing effect of the side barrier assembly, but also prevents the side barrier rod from accidentally loosening due to vibration or impact during transportation. In addition, through the synergistic effect of multiple fixing points and locking mechanisms, multiple protections for the carton are formed, thereby further improving the packaging quality and greatly reducing the risk of accidents during transportation.

[0021] 3. The present application adopts the curvature design of the control groove. As the control circular plate rotates, the pressure rod not only slides along the control groove, but also moves along the slide groove and the control groove to the side away from the center of the control circular plate, so that the pressure rod is pressed tightly on the top of the pad. The pressure on the pad will be evenly distributed to the topmost carton, and the friction between the cartons will fix the cartons on the entire pallet together, thereby preventing the cartons from shifting or tipping over during transportation, thereby greatly improving the packaging effect and transportation stability of the cartons.

The functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] See also Figure 1 and Figure 3 In the present embodiment, an automatic stacking and packaging device for cold drink carton packaging is proposed, comprising a pallet 1 for carrying a carton 2 and two mounting plates 3 symmetrically mounted on the top of the pallet 1, a pressing and locking unit 4 is commonly arranged between the two mounting plates 3, the pressing and locking unit 4 comprises a pressing component 401 and a control component 402 for controlling the pressing component 401 to press the carton 2, a triangular locking unit 5 is arranged between the pallet 1 and the mounting plate 3, the triangular locking unit 5 comprises two triangular fixing components 501 symmetrically, a tightening component 502 for tightening the triangular fixing components 501 and two pressing components 503 symmetrically, a side block locking unit 6 is commonly arranged between the two triangular fixing components 501, the side block locking unit 6 comprises two side block components 601 symmetrically front and back and a locking component 602 for reinforcing the side block component 601.

[0033] See also Figure 1 , Figure 2 , Figure 5, Figure 6 and Figure 7 The clamping assembly 401 includes a pad 4014 placed on the top of the top carton 2 and a rotating rod 4011 rotatably installed between the two mounting plates 3 and passing through the two mounting plates 3, and a control circular plate 4012 is commonly installed at both ends of the rotating rod 4011. The tensioning assembly 502 includes two mounting cylinders 5021 fixedly installed between the left and right inner walls of the tray 1 and symmetrically front and back, and a tensioning rod 5026 slidably connected in the mounting cylinder 5021. The triangular fixing assembly 501 includes a clamping rod 5017 rotatably installed on the side of the control circular plate 4012 away from the rotating rod 4011 and a hinge sleeve 5011 clamped on the outside of the clamping rod 5017. Two locking rods 5012 symmetrically front and back are hinged on the hinge sleeve 5011, and the two locking rods 5012 are respectively hooked with the front and rear tensioning rods 5026.

[0034] See also Figure 2 , Figure 5 , Figure 6 and Figure 7 The triangular fixing assembly 501 also includes an annular hook groove 5013 provided on the tensioning rod 5026, and the locking rod 5012 is hook-shaped at one end close to the tensioning rod 5026 and hooked in the annular hook groove 5013. Two installation cavities 5014 symmetrical in upper and lower directions are provided in the hinge sleeve 5011, and a return spring 5015 is fixedly installed on the inner wall of the adjacent side of the two installation cavities 5014, and a buckle 5016 is fixedly installed on the adjacent end of the two return springs 5015, and the buckle 5016 is triangular-shaped on the side away from the return spring 5015, and a clamping groove clamped with the buckle 5016 is provided on the outer side of the clamping rod 5017.

[0035] When in use, after the palletizer completes automatic palletizing and moves the fully loaded pallet 1 to the packaging area through the conveyor line, the left and right hinge sleeves 5011 are respectively sleeved on the outside of the two clamping rods 5017 and the hinge sleeves 5011 are pushed toward the side close to the mounting plate 3. During this process, the clamp 5016 first squeezes the end of the clamping rod 5017 to shrink the return spring 1 5015, thereby driving the clamp 5016 to shrink into the mounting cavity 5014. When the clamp 5016 moves to the clamping groove, the return spring 1 5015 is reset, driving The buckle 5016 is snapped into the snap-in groove (at this time, you can hear the sound of the buckle 5016 snapping into the snap-in groove, which is convenient for judging whether the buckle 5016 is snapped into the snap-in groove), thereby completing the fixation of the articulated sleeve 5011. Then, the hook-shaped sections at the bottom ends of the two locking rods 5012 on the same articulated sleeve 5011 are overlapped on the outside of the two corresponding front and rear annular hook grooves 5013, so that the bottom ends of the hook-shaped sections are located below the annular hook grooves 5013. In other words, the two locking rods 5012 are not locked and fixed at this time, thereby initially forming a triangular structure.

[0036] See also Figure 1 , Figure 3 and Figure 7 A plurality of reinforcing plates are arranged between the top inner wall and the bottom inner wall of the tray 1, and the mounting tube 5021 is fixedly passed through the plurality of reinforcing plates. The tensioning assembly 502 also includes two fixed tubes 5022 which are fixedly mounted on the bottom inner wall of the tray 1 and are symmetrical front to back. A baffle 5024 is fixedly mounted on the bottom inner wall of the fixed tube 5022 through a second reset spring 5023, and a reset plate 5025 is fixedly mounted on the top of the baffle 5024 through a round rod. The two reset plates 5025 are respectively fixedly connected to the front and rear tensioning rods 5026, and the length of the round rod is greater than the height of the fixed tube 5022, so that the baffle 5024 always remains in the state of being located in the fixed tube 5022, thereby preventing gravel and dust from entering the second reset spring 5023 through the mounting tube 5021.

[0037] See also Figure 7 Two groups of limit cylinders 5027 are fixedly installed on the inner wall of the bottom of the tray 1, and the single group of limit cylinders 5027 is symmetrically arranged left and right. Two limit rods 5028 are fixedly installed on the bottom of the two tension rods 5026, and the limit rods 5028 at the bottom of the two tension rods 5026 are slidably connected with the two groups of limit cylinders 5027 front and back respectively.

[0038] It should be noted that the limiting rod 5028 limits the tension rod 5026 during the process of the tension rod 5026 sliding up and down, thereby preventing the tension rod 5026 from deflecting.

[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The control component 402 includes an arc-shaped control groove 4021 opened on the mounting plate 3, and a slide groove 4022 is opened on the control circular plate 4012. A pressure rod 4013 is slidably connected in the left and right slide grooves 4022. The pressure rod 4013 is slidably connected in the control groove 4021, and one end of the pressure rod 4013 close to the control circular plate 4012 is slidably connected in the slide groove 4022. The rotation of the control circular plate 4012 will drive the pressure rod 4013 to slide along the control groove 4021 and move along the slide groove 4022 to the side away from the center of the control circular plate 4012, so that the pressure rod 4013 presses the pad 4014.

[0040] When in use, after forming the triangular fixed structure, the pad 4014 is placed on the top of the top carton 2 to provide a flat surface for subsequent compaction so as to evenly apply pressure. Then, the control circular plate 4012 is rotated. During the rotation process, due to the arc design of the control groove 4021 (the center of the control groove 4021 is located below the center of the control circular plate 4012), the pressure rod 4013 will slide along the control groove 4021. As the control circular plate 4012 rotates, the pressure rod 4013 not only moves along the control groove 4021, but also moves along the control groove 4021. As the control groove 4021 slides, the pressure rod 4013 will also move along the slide groove 4022 and the control groove 4021 to the side away from the center of the control circular plate 4012, so that the pressure rod 4013 gradually approaches the pad 4014 and is finally pressed against the top of the pad 4014. The pressure on the pad 4014 will be evenly distributed to the topmost carton 2, and then the friction between the cartons 2 will fix the cartons 2 on the entire pallet 1 together, preventing the cartons 2 from shifting or tipping over during transportation.

[0041] See also Figure 3 and Figure 4 The pressing assembly 503 includes a guide groove 5031 provided in the mounting plate 3 and a pressing plate 5032 slidably connected in the guide groove 5031. The bottom of the pressing plate 5032 slides through the top inner wall of the tray 1 and is fixedly connected to the front and rear tensioning rods 5026 through a connecting rod 5033.

[0042] See also Figure 1 and Figure 4 The top of the guide groove 5031 is connected to the bottom of the control groove 4021, and a triangular protrusion is provided on the top of the lower pressure plate 5032. The pressure rod 4013 slides along the control groove 4021 and squeezes the triangular protrusion to drive the lower pressure plate 5032 to move downward, so that the tightening rod 5026 moves downward, and drives the triangular fixing assembly 501 to tighten and lock.

[0043] When in use, as the pressure rod 4013 gradually approaches the pad 4014 and is finally pressed against the top of the pad 4014, the pressure rod 4013 slides along the control groove 4021 and squeezes the triangular protrusion on the top of the lower pressure plate 5032, thereby driving the lower pressure plate 5032 to move downward and pushing the front and rear tensioning rods 5026 to move downward synchronously through the connecting rod 5033 and compress the return spring 2 5023. As the tensioning rod 5026 moves downward, the hook-shaped section of the locking rod 5012 is pulled downward, so that the tensioning rod 5026 is tightened. After the tensioning rod 5026 moves downward and is tightened, it can play the effect of limiting the reversal of the pressure rod 4013. When the pressure rod 4013 moves to a position slightly behind the triangular protrusion (that is, When the pressure bar 4013 has just passed the triangular protrusion, the pressure bar 4013 is located at the end of the control groove 4021. The triangular protrusion can further prevent the pressure bar 4013 from reversing, thereby greatly improving the stability of the pressure bar 4013. At this time, a locked and fixed stable triangular packaging structure is formed between the hinge sleeve 5011 and the pressure bar 4013, the front tensioning rod 5026 and the rear tensioning rod 5026. The triangular structure can evenly distribute the pressure applied thereto to each fulcrum, avoiding structural damage or failure caused by excessive force on a single point. At the same time, due to the even distribution of pressure, the friction between the cartons 2 is also more even, further enhancing the stability of the entire palletizing and preventing the cartons 2 from shifting or tipping over during transportation.

[0044] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 The side block assembly 601 includes a connecting sleeve 6013 fixedly installed on the outside of the locking rod 5012, the connecting sleeve 6013 is located above the hook-shaped section of the locking rod 5012, and a side block rod 6011 is rotatably installed on one side of the left and right connecting sleeves 6013. The top of the side block rod 6011 is hook-shaped, and two side hook grooves 603 are provided on the front and rear sides of the pad 4014. The four side hook grooves 603 are distributed in a square shape. The tops of the two rear side block rods 6011 are hooked with the two rear side hook grooves 603, and the tops of the two front side block rods 6011 are hooked with the two front side hook grooves 603.

[0045] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 A socket 6014 is fixedly installed in the middle of the side guard rod 6011, and a plug 6012 is inserted between the two sockets 6014 opposite to each other on the left and right. The plug 6012 is fixed to the socket 6014 on the right side through a nut.

[0046] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 , the middle parts of the front and rear two bolts 6012 are provided with slots that pass through from top to bottom, and the latch assembly 602 includes a U-shaped latch rod 6021, and the two vertical sections of the U-shaped latch rod 6021 are respectively inserted into the two slots, and the bottom ends of the two vertical sections of the U-shaped latch rod 6021 are provided with external threads, and the top of the tray 1 is rotatably installed with two front and rear symmetrical threaded sleeves 6022, and the two threaded sleeves 6022 are respectively threadedly connected with the two vertical sections of the U-shaped latch rod 6021.

[0047] When in use, after forming the triangular fixed structure and covering the pad 4014 on the top of the top carton 2, before rotating the control circular plate 4012, the hook-shaped section at the top of the side blocking rod 6011 is hooked with the corresponding side hook groove 603, and then the tensioning rod 5026 is driven downward by the connecting rod 5033 on the lower pressing plate 5032. During the tightening process of the triangular fixed structure, the side blocking rod 6011 is synchronously driven to move downward and hook the side hook groove 603 through the connecting sleeve plate 6013. Then, the two plugs 6012 are respectively inserted in The two sets of sockets 6014 are aligned on the left and right and two plugs 6012 are fixed by nuts, and then the two vertical sections of the U-shaped locking rod 6021 are respectively inserted into the slots of the front and rear plugs 6012 from top to bottom, and finally the threaded sections at the bottom ends of the two vertical sections of the U-shaped locking rod 6021 are respectively inserted into the two threaded sleeves 6022, and the two threaded sleeves 6022 are rotated to fix the U-shaped locking rod 6021, so as to further fix the side guard rod 6011 and the plug 6012 and realize all-round blocking protection for the carton 2 on the top of the pallet 1.

[0048] When the carton 2 needs to be unloaded after being transported to the destination, the two threaded sleeves 6022 are first rotated to release the fixation of the U-shaped locking rod 6021, and then the U-shaped locking rod 6021 is pulled out from the slot. Next, the nut is rotated to release the fixation of the bolt 6012 and the screw is pulled out from the sleeve 6014. After pulling out, the control circular plate 4012 is rotated in the opposite direction to drive the pressure rod 4013 to slide along the control groove 4021, first passing over the triangular protrusion and disengaging from the triangular protrusion, so that the pressure on the reset spring 5023 is released and reset occurs, driving the tension rod 5026 to move upward for reset. At the same time, as the pressure rod 4013 slides along the control groove 4021 and the slide groove 4022, it will gradually slide to the side close to the center of the control circular plate 4012, from The pressure on the pad 4014 is released, and then the pad 4014 is removed. After the tensioning rod 5026 is completely reset, the hook section at the bottom end of the locking rod 5012 is taken out from the annular hook groove 5013 on the tensioning rod 5026, and the hook section of the side baffle rod 6011 is taken out from the side hook groove 603, and finally the hinge sleeve 5011 is pulled out from the clamping rod 5017. During the pulling out process, the buckle 5016 will squeeze the inner wall of the clamping groove, causing the reset spring 5015 to contract, thereby driving the buckle 5016 to contract and squeeze into the installation cavity 5014, until the buckle 5016 is pulled out from the outside of the clamping rod 5017, and the reset spring 5015 drives the buckle 5016 to reset, thereby completing the unlocking of the entire packaging device, and then the carton 2 can be removed.

[0049] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
