Description

Technical Field

[0001] The present invention relates to the technical field of carton folding, and in particular to a multifunctional device for folding carton during transportation. Background Art

[0002] With the development of the Internet, online shopping has become an essential lifestyle for everyone, because the convenience it brings allows people to buy their favorite items without leaving home, and the logistics industry must be the one that creates this convenience.

[0003] Logistics, which originally means "physical distribution" or "goods delivery", is a part of the supply chain activities. It is the process of planning, implementing and controlling the efficient and low-cost flow and storage of goods, service consumption and related information from the place of production to the place of consumption in order to meet customer needs. Logistics is centered on warehousing and promotes the synchronization of production and the market. Logistics is the whole process of planning, implementing and managing the transportation of raw materials, semi-finished products, finished products and related information from the place of production to the place of consumption of goods at the lowest cost through transportation, storage and distribution in order to meet customer needs.

[0004] In this process, the items need to be packaged, and folding cartons are commonly used. This folding carton is packaged by folding. Under normal conditions, the bottom of the carton is closed, and then the top is used to store the items, and then the top is folded and packaged. After the packaging is completed, the carton is transported. In China, Patent Publication No.: CN211870957U discloses a carton stacking mechanism, including an upstream conveyor belt and a downstream conveyor belt. The downstream conveyor belt includes a base and a plurality of belt bodies parallel to each other arranged above the base. There is a gap between adjacent belt bodies. The real-time straightening and alignment of the cartons are achieved by a carton straightening device and a carton blocking device. After each carton falls, the vertical straightening roller will move it into place, thereby ensuring the neatness of the carton stack. After a certain number of cartons are stacked on the downstream conveyor belt, the upstream conveyor belt is stopped, the downstream conveyor belt is opened, and the carton stack is sent out.

[0005] However, the cartons in this process are not formed and are still in a two-dimensional state, so there is no need to consider the folding problem during the conveying process. If folding is not performed, the stacking method cannot be completed. Therefore, in order to utilize the convenience of this double-layer conveying and stacking, it is urgent to propose a multifunctional device that can fold cartons during conveying.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0054] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0055] Logistics is the entire process of planning, implementing and managing the transportation, storage and distribution of raw materials, semi-finished products, finished products and related information from the place of production to the place of consumption of goods in order to meet the needs of customers at the lowest cost.

[0056] In this process, the items need to be packaged. The most commonly used is folding cartons. This type of folding carton is packaged by folding. Under normal circumstances, the bottom of the carton is closed, and then the top is used to store the items. The top is then folded and packaged. After packaging, the carton is transported, but many of them are two-dimensional cartons. Therefore, there is no need to consider the folding problem during the transportation process. If folding is not performed, the commonly used method of stacking after transportation cannot be completed.

[0057] To this end, the present invention provides a multifunctional device for folding cartons during transportation, the purpose of which is to complete the folding of cartons during transportation, such as Figure 1 As shown, the device consists of a conveying system 100 for conveying the box 300 and a folding system 200 for folding the box 300 during the conveying process. First, the conveying system 100 is the same as the prior art, mainly including an upper and a lower structure. The upper structure is used to convey the box 300, and the lower structure is used to support the box 300. The stacking process is completed in the lower structure, but the upper structure is required to convey the box 300 successively. The specific principle has been disclosed in the prior art, so it will not be repeated here.

[0058] During the transportation process, the box body 300 is folded by the folding system 200. Figure 3 In the embodiment, the folding system 200 includes a short plate folding component 210 and a long plate folding component 220, and both the short plate folding component 210 and the long plate folding component 220 are installed on the conveying path of the conveying system 100. The short plate folding component 210 is arranged closer to the conveying starting point of the conveying system 100 than the long plate folding component 220. When the box 300 is conveyed, it first contacts the short plate folding component 210, and then the short plate folding component 210 applies downward pressure to the inner layer of the box 300 during the movement, and then contacts the long plate folding component 220. The long plate folding component 220 squeezes the outer layer of the box 300 from the side to complete the folding operation of the inner and outer layers of the box 300 in turn, so as to complete the packaging of the box 300 during the conveying process, and then the stacking of cartons in a three-dimensional state is realized with the help of the conveying system 100.

[0059] In summary, adding a folding system 200 to the conveying system 100 can achieve stacking of cartons in two or three dimensions. The same conveying device can be used in both the production stage and the use stage of cartons, and the problem of carton packaging is also solved during the use stage.

[0060] It should be noted that the folding direction of the inner plate of the box body 300 is parallel to the conveying direction of the conveying system 100, and the folding direction of the outer plate is perpendicular to the conveying direction of the conveying system 100, thereby ensuring that the short plate folding component 210 and the long plate folding component 220 are in smooth contact with the box body 300.

[0061] For the first embodiment, please refer to Figure 2 As shown, the conveying system 100 includes a conveying device 120 forming an upper structure and a table 110 forming a lower structure. Considering that the box body 300 still needs to be sealed after folding, the table 110 does not have a conveying capability, but only receives the box body 300, and then after manual sealing (usually adhesive tape is pasted, and the box body 300 can be selectively checked after pasting to ensure the stability of folding and sealing), the box body 300 is finally placed on the table 110, waiting to receive the next box body 300, thereby completing the stacking operation.

[0062] exist Figure 3 In the figure, the conveying device 120 includes a frame 121 and a conveyor belt 122. The conveyor belt 122 is wrapped around the frame 121. The frame 121 is installed on the platform 110, and then the overall rotation is completed by the cooperation of the rotating roller and the motor. The rotated conveyor belt 122 transports the box 300, and the short plate folding component 210 and the long plate folding component 220 are both mounted on the frame 121. In this embodiment, because the problem of lifting and lowering the conveying device 120 is not considered, the short plate folding component 210 and the long plate folding component 220 can also be mounted on the platform 110.

[0063] Combination Figure 5 As shown, the short board folding component 210 includes two side frames 211 and a short board press 213. The short board press 213 is arranged between the two side frames 211 and is connected to the side frames 211 so that it can be raised and lowered. Specifically, the side frames 211 and the short board press 213 are connected by a second hydraulic rod 212, and the short board press 213 is raised and lowered by the second hydraulic rod 212. The raising is to ensure that the box body 300 can enter the bottom of the short board press 213, and the lowering is to form a downward pressure on the inner plate, that is, the inner plate is bent inward by the action of the short board press 213 to realize the folding of the inner plate.

[0064] In this embodiment, the short plate pressing piece 213 is a plate-shaped structure, and its purpose is to directly act on the inner layer plate to make it fold inward.

[0065] Combination Figure 6As shown, the long plate folding component 220 includes two groups of active ends respectively arranged on both sides of the conveyor belt 122, each group of active ends includes a bottom frame 221 and a top frame 222, the top frame 222 is telescopically installed on the bottom frame 221, and then cooperates with the bottom frame 221 to form a lifting structure, which can be specifically connected by an electric push rod to achieve a lifting effect, and the active end also includes a side extension plate 223, which is telescopically connected to the top frame 222, and the top frame 222 is lifted and lowered on the bottom frame 221 under the action of the electric push rod, and the bottom frame 221 is preferably installed on the frame body 121, and the height of the side extension plate 223 carried by the lifting top frame 222 is adjusted. When in use, the heights to which the short plate pressing piece 213 and the top frame 222 need to rise are preset , for the short plate pressing piece 213, it is to make a lifting reciprocating motion. The purpose of the short plate pressing piece 213 rising is to allow the box body 300 to enter below it, that is to say, the height requirement of the short plate pressing piece 213 rising is: the bottom surface height of the short plate pressing piece 213 must be higher than the height of the inner layer plate of the box body 300 when it is vertical; for the top frame 222, as long as the height is preset for the first time, the top frame 222 does not need to adjust the height later (only the same type of box body 300 is folded), because the purpose of adjusting the height is to ensure that the telescopic side extension plate 223 can squeeze the outer layer plate of the box body 300. It is preferred to adjust the lower action point of the side extension plate 223 to a position equal to the height after the outer layer plate is folded, so as to complete the 90-degree folding operation of the outer layer plate;

[0066] After the preset height is completed, the conveyor belt 122 rotates after the motor is started, and then the box 300 is placed on the conveyor belt 122. Fig. 9 As shown, the conveyor belt 122 drives the box body 300 to move toward the short plate pressing piece 213, and then enters below the short plate pressing piece 213. At this time, the short plate pressing piece 213 is driven by the second hydraulic rod 212 to lower its height, and contacts the inner plate of the box body 300 during the process of lowering its height. At this time, the inner plate of the box body 300 is required to be in a vertical or slightly folded inward, preferably folded inward by 5-15 degrees, so that the inner plate is folded inward with the downward pressure of the short plate pressing piece 213 after contact, so as to achieve the purpose of folding;

[0067] During the above process, the box body 300 is continuously moved under the drive of the conveyor belt 122. In this way, after the inner layer plate is folded, the box body 300 is separated from the short plate pressing piece 213. At this time, the second hydraulic rod 212 can drive the short plate pressing piece 213 to reset, so as to fold the inner layer plate of the next box body 300. At the same time, the box body 300 with the inner layer plate folded gradually enters the position between the two top frames 222. At this time, the side extension plate 223 moves horizontally inward under the support of the top frame 222 and contacts the outer layer plate of the box body 300. As the side extension plate 223 moves horizontally, the outer layer plate is gradually It gradually bends inward until it is in a folding state of 90 degrees. At this time, as the box body 300 moves, the bottom surface of the side extension plate 223 acts on the crease of the outer plate and squeezes it to ensure the folding quality of the outer plate. There is no need to consider the inner plate here because the function of the inner plate is to support the outer plate, so there is no need to require it to be fixed at 90 degrees after folding. On the contrary, the inner plate slightly tilted upward can also improve the support effect on the outer plate, and as long as the outer plate is fixed, the inner plate is naturally restricted, so there is no need to consider the folding quality of the inner plate;

[0068] Finally, after the folding is completed, the box 300 is separated from the conveyor belt 122 and falls onto the platform 110. Then the staff sticks tape on the outer layer, and the subsequent boxes 300 are stacked upward as the conveyor belt 122 conveys them. Preferably, two layers are stacked. Because the box 300 is different from the carton in a two-dimensional state, the box 300 contains items, so the weight is increased. If the stacking number of layers is too high, it is easy to tip over, and the falling box 300 is easy to hit itself or other boxes 300.

[0069] It is further explained that if Figure 6 As shown, in order to protect the outer layer plate, a pressure wheel 2231 is preferably provided at the end of the side extension plate 223, and the rolling of the pressure wheel 2231 when contacting the outer layer plate reduces the damage caused by friction.

[0070] In addition, it is preferred that the openings of the box body 300 on the two upper frames 222 are opened outwardly, so that even if the outer plate of the box body 300 is bent outwardly, it can be adjusted with the help of the upper frames 222 during the movement.

[0071] The tops of the two side frames 211 are bent toward each other and then bent downward at the bent ends, thereby forming a "U"-shaped structure with an opening downward, and a side channel 211A is formed in the "U"-shaped structure, whose function is to allow the unfolded outer layer plate to pass smoothly, and the downwardly bent part is to ensure the descending distance of the short plate press 213. Because the second hydraulic rod 212 is installed on the downwardly bent part of the side frame 211, the minimum height to which the short plate press 213 can descend depends on the length of the downwardly bent part of the side frame 211.

[0072] like Fig.11As shown, the two top frames 222 or two groups of active ends in this embodiment are arranged opposite to each other.

[0073] A box 300 in which the inner layer plate can be folded inward under pressure is further disclosed to cooperate with the short plate folding member 210 to better complete the folding operation. Figure 4 As shown, the box body 300 includes a side plate 310, and the top and bottom of the side plate 310 are both provided with openings. The bottom opening is sealed by a bottom sealing layer, and the top opening is sealed by a top sealing layer. The top sealing layer is in an open state during the transportation process. The purpose of the short plate folding member 210 and the long plate folding member 220 is to complete the folding operation of the top sealing layer, and the bottom sealing layer is already sealed when the items are filled, wherein:

[0074] The top sealing layer includes two short plates 320 and two long plates 330 arranged opposite to each other. The inner plate is formed by the short plates 320, and the outer plate is formed by the long plates 330. The bottom sealing layer can also be sealed by the same structure. The sealing method is to first fold the inner plate inwards, then fold the outer plate inwards, and seal the outer plate with glue.

[0075] The improvement lies in that an inner folding end 320a is provided at the top of the short plate 320, and the inner folding end 320a has an inclined surface inclined inwardly at the top, so that the inner folding end 320a in the vertical state can be folded inward autonomously after being compressed, without deliberately tilting the short plate 320 slightly inward.

[0076] For the second embodiment, please refer to Figure 7 As shown, the short plate pressing piece 213 is a box-shaped structure, so there is an inner cavity 213A in the short plate pressing piece 213, and its top and bottom are both hollowed out, thereby forming through openings at the top and bottom, and a sealing plate 214 is placed from the top through opening into the inner cavity 213A. In addition, a glue box 215 is provided on the outside of the short plate pressing piece 213 to cooperate with the sealing plate 214 for sealing glue.

[0077] A more specific structure is Figure 8 As shown, a guide plate 2131 is rotatably connected in the bottom opening of the short plate pressing piece 213, and the guide plate 2131 is connected to the short plate pressing piece 213 through an elastic member. For example, a rotating shaft 2132 arranged on both sides of the guide plate 2131 is hinged to the short plate pressing piece 213, and then flanges are arranged on both sides of the rotating shaft 2132, and a torsion spring is fixedly connected between the flange and the short plate pressing piece 213, so that the sealing plate 214 in the inner cavity 213A is supported by the guide plate 2131.

[0078] In addition, the guide plate 2131 is initially tilted downward, thereby forming a plate outlet slit 213B between the guide plate 2131 and the bottom opening. The plate outlet slit 213B is located on one side above the box body 300, specifically on the side where the box body 300 is to be separated from the short plate pressing piece 213. At the same time, a glue outlet 213C is provided on the side where the plate outlet slit 213B is located. The glue outlet 213C is connected to the glue box 215. Under the action of gravity, the glue stored in the glue box 215 can flow out through the glue outlet 213C. However, the glue outlet 213C itself has a certain tension. Therefore, the glue cannot seep out before the sealing plate 214 contacts the glue outlet 213C, or only a small amount seeps out, but does not affect the overall use.

[0079] Combination Fig.10 The working principle of this embodiment is disclosed as follows:

[0080] First, it is necessary to preset the rising height of the short plate press 213 and the top frame 222. There is no special requirement for the top frame 222, but in the present embodiment, the short plate press 213 does not need to perform reciprocating motion of lifting and lowering. Therefore, the short plate press 213 is set at a height through which the short plate 320 can pass. In the present embodiment, the downward pressure on the short plate 320 is achieved with the help of the sealing plate 214. Then the box body 300 is placed on the conveyor belt 122. Driven by the conveyor belt 122, the box body 300 enters the bottom of the short plate press 213. At this time, the inner folding end 320a will contact the sealing plate 214 exposed from the plate outlet seam 213B at the tail end of the short plate press 213. Previously, the end of the sealing plate 214 had been in contact with the glue seeping out of the glue outlet 213C for a long time, so the glue at this end has passed through the sealing plate 214. At this time, the inner folding end 320a in contact with its end The closing plate 214 can be stuck to the closing plate 214, and the box body 300 continues to move. With the help of the guiding effect of the guide plate 2131, the closing plate 214 is successfully pulled out by the inner folding end 320a (the subsequent closing plate 214 is filled under the action of gravity and the pulling force of the closing plate 214, that is, once the closing plate 214 is completely moved out, a new closing plate 214 will be exposed at the plate outlet gap 213B), until the closing plate 214 is separated from the guide plate 2131, the closing plate 214 will be hit to the inner folding end 320a on the other side by its own gravity. At this time, under the action of the closing plate 214, downward pressure is applied to the entire short plate 320, and then the two short plates 320 after being stressed are folded inwardly with the help of the inclined surface of the inner folding end 320a. At this time, the folding operation of the inner layer plate is completed. Not only that, under the connection of the closing plate 214, the short plate 320 has stronger shaping and supporting capabilities.

[0081] Moreover, the sealing plate 214 is attached to the glue outlet 213C during the sliding out process (the glue outlet 213C can be a retractable liquid seepage structure in this process to improve the quality of glue discharge and avoid the sealing plate 214 not being attached to the glue outlet 213C, resulting in discontinuity in glue attachment). In this way, the glue outlet 213C discharges glue, and the glue adheres to the sealing plate 214 after the glue is discharged, and then follows the box body 300 into between the two top frames 222. After entering the top frames 222, the side extension plate 223 extends out, and the extended side extension plate 223 acts on the long plate 330 to fold it inward. After folding 90 degrees, the long plate 330 is attached to the sealing plate 214, and at this time, glue is attached to the top of the sealing plate 214. At this time, the glue sealing of the long plate 330 is completed. No manual intervention is required in the entire sealing process. The long plate 330 sealed by the sealing plate 214 can block the gap in the middle to protect the items in the side plate 310.

[0082] By sealing the inner side with glue through the sealing plate 214, when disassembling later, it can be directly torn along the gap formed by folding the long plate 330, and it is difficult to restore after tearing, thereby preventing someone from deliberately opening the box 300 during logistics transportation, and further improving the safety of the items in the box 300. In summary, the device is more suitable for the folding operation of cartons in the logistics industry, but it does not rule out the use in other fields, so the protection scope of the device is not limited to the logistics field.

[0083] It should be noted that the two ends of the sealing plate 214 have a 2-3 cm long permeable layer to allow the glue to penetrate the sealing plate 214, so that the sealing plate 214 can be bonded to the two short plates 320.

[0084] See also Fig.12 As shown, the two top frames 222 or the two groups of working ends in this embodiment are staggered. Considering that the long board 330 is in close contact with the sealing board 214, if the side extension boards 223 are relatively arranged, they cannot be extended for a long distance. Therefore, the side extension boards 223 need to be retracted before they reach the position of the sealing board 214. The staggered side extension boards 223 can be extended for a longer distance, so as to increase the pressure of the long board 330 in contact with the sealing board 214 and ensure the reliability of the contact between the two.

[0085] In this embodiment, the box body 300 can be sealed by itself, so there is no need to stay on the conveyor belt 122 after the folding operation is completed (the purpose of staying is to facilitate manual sealing by pasting), so after the folding operation is completed, the conveyor belt 122 can directly transport the box body 300 to the lower structure. The lower structure in this embodiment can be a roller transmission structure or a belt transmission structure, which uses the transmission structure to transport single or stacked boxes 300 (the stacking method includes the box body 300 naturally falling to the box body 300 below under the height difference, or it can be manually transported to the box body 300 below, or it can be transported by a robotic arm).

[0086] For the third embodiment, please refer to Fig.13 As shown, an extension platform 111 is provided on the platform 110, and the bearing surface at the top of the extension platform 111 extends outward, so that it can better bear. In addition, a first hydraulic rod 112 is provided between the conveying device 120 and the platform 110. The first hydraulic rod 112 is provided to realize the lifting and lowering of the conveying device 120. On the one hand, the falling height of the box body 300 can be adjusted, which is more convenient for stacking control, and on the other hand, it is convenient to use with the extension platform 111. Please refer to Fig.14 As shown, an extrusion channel is formed between the extension platform 111 and the conveyor belt 122, and the lifting and lowering of the conveying device 120 can adjust the extrusion thickness of the extrusion channel. Its function is to extrude the cartons in a two-dimensional state so that they can maintain a two-dimensional state, which is more convenient for stacking during transportation. However, this needs to be done separately and cannot be done simultaneously with the conveyor belt 122.

[0087] In addition, in this embodiment, the short plate folding member 210 and the long plate folding member 220 can only be carried on the conveying device 120 .

[0088] Based on the above embodiments, the present invention further proposes a folding method of a multifunctional device for folding cartons during transportation, which includes the following method steps:

[0089] Step 1: The conveying system 100 conveys the box 300;

[0090] Step 2: During the conveying process, the inner layer of the box body 300 is first folded inwards under the downward pressure released by the short plate pressing piece 213;

[0091] Step 3: During the continuous conveying process, the outer plate of the box body 300 is folded inwards under the pressure of the side extension plate 223 .

[0092] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
