Description

Technical Field

[0001] The present application relates to the technical field of folding box devices, and in particular to a material taking mechanism and a folding box device with a function of preventing cardboard adhesion. Background Art

[0002] The folding box device adsorbs cardboard through a material taking mechanism and then completes the feeding. However, during the feeding process, the cardboard itself is stacked, which is likely to cause relative vacuum between the cardboard and the cardboard, and then "adhesion" occurs between the upper and lower layers of cardboard due to the vacuum, resulting in the folding box device being unable to continuously feed normally one by one. When the material taking mechanism extracts the cardboard, the extracted cardboard often pulls up the lower layer of cardboard together and causes the lower layer of cardboard to shift. The shifted cardboard may stay between the feeding table and the folding box station, causing the subsequent material taking mechanism to be unable to take materials normally; or directly enter the folding box station, forming double-layer or multi-layer cardboard folding, causing jamming and damage to the folding box mechanism, resulting in the folding box device malfunctioning and shutting down and unable to operate normally.

[0003] The existing solutions are to first stand the opened cardboard stack on its side, loosen the cardboard stack by vibrating and then stack it on the upper material taking table, or blow air with a high-pressure air gun on the side of the cardboard stack to reduce the relative vacuum between the cardboard and the cardboard. These measures all have a certain effect on preventing cardboard adhesion, but they cannot completely eliminate the adhesion between the cardboard, and at the same time, a large amount of manual assistance is required, resulting in a low degree of automation of the folding box device and being unable to be directly connected to an automated packaging production line.

[0004] Therefore, it is necessary to design a material taking mechanism with a function of preventing cardboard adhesion to solve the above problems. Content of the Utility Model

[0005] In view of this, in order to overcome the defects of the prior art, the present utility model provides a material taking mechanism and a folding box device with a function of preventing cardboard adhesion, effectively solving the problems in the prior art that the adhesion between the cardboard cannot be completely eliminated, and at the same time, a large amount of manual assistance is required, resulting in a low degree of automation of the folding box device and being unable to be directly connected to an automated packaging production line.

[0006] According to a first aspect of the present utility model, a material taking mechanism with a function of preventing cardboard adhesion is provided for a box folding device. The box folding device includes a structural frame. Among them, the material taking mechanism with a function of preventing cardboard adhesion includes a feeding assembly and a guiding and separating assembly. The feeding assembly is used for placing a cardboard stack and feeding cardboard. The guiding and separating assembly is arranged on the side of the feeding assembly to separate the adhered cardboard. The guiding and separating assembly includes a guiding limiting plate and a scraping edge limiting block. The scraping edge limiting block is arranged on the upper part of the guiding limiting plate. The guiding limiting plates are arranged at both the first end and the second end of the cardboard stack. The scraping edge limiting block is located above the cardboard stack. The distance between two mutually facing surfaces of the two scraping edge limiting blocks is smaller than the distance between the first end and the second end of the cardboard stack.

[0007] Preferably, the scraping edge limiting block is provided with a transition rounded corner or an inclined surface, so that the overall height of the scraping edge limiting block gradually decreases from outside to inside.

[0008] Preferably, the material taking mechanism with a function of preventing cardboard adhesion can be switched between a stopped state and a working state. When the material taking mechanism with a function of preventing cardboard adhesion is in the stopped state, the cardboard stack is located below the scraping edge limiting block. When the material taking mechanism with a function of preventing cardboard adhesion is in the working state, the feeding assembly sucks the cardboard located at the top of the cardboard stack, and drives the cardboard at the top to abut and slide against the scraping edge limiting block until it is separated from the scraping edge limiting block.

[0009] Preferably, the guiding and separating assembly further includes a gap adjusting member. One end of the gap adjusting member is adjustably connected to the guiding limiting plate, and the other end of the gap adjusting member is adjustably connected to the structural frame. The guiding limiting plate can adjust the distance from the cardboard stack through the gap adjusting member.

[0010] Preferably, the scraping edge limiting block is detachably arranged on the guiding limiting plate.

[0011] Preferably, the size of the scraping edge limiting block in the first direction is smaller than the size of the guiding limiting plate in the first direction.

[0012] Preferably, the size of the scraping edge limiting block in the second direction is 3-5 times the thickness of the cardboard; the size of the scraping edge limiting block in the third direction is 4-6 times the thickness of the cardboard.

[0013] Preferably, the feeding assembly includes a lifting and picking member and a feeding table. The lifting and picking member is disposed above the feeding table. The cardboard stack is placed on the feeding table. The guiding and limiting plates are disposed on both sides of the feeding table, and the edge scraping and limiting blocks are located at the upper parts of both sides of the feeding table.

[0014] Preferably, the feeding table is slidably disposed on the structural frame. The feeding assembly further includes an opposed photoelectric switch, which is disposed on the guiding and limiting plate, and the installation position of the opposed photoelectric switch is close to the installation position of the edge scraping and limiting block.

[0015] According to a second aspect of the present invention, there is provided a folding box device, wherein the folding box device includes the picking mechanism with the function of preventing cardboard adhesion as described above.

[0016] With the picking mechanism having the function of preventing cardboard adhesion according to the present invention, through the cooperation of the feeding assembly and the guiding and separating assembly, normal and continuous picking of cardboard can be achieved. The guiding and separating assembly's guiding and limiting plates and edge scraping and limiting blocks can separate the adhered cardboard. When picking up, if the lower cardboard adheres and is lifted, due to the deformation and bending of the upper cardboard, a travel space gap is generated between the two adjacent adhered cardboard pieces, and they are no longer closely stacked. Air enters the gap of the corresponding travel space. When the edge of the lower cardboard abuts against the edge scraping and limiting block, due to insufficient traction force above, the lower cardboard is forcibly "pulled down" and continues to stay on the feeding table waiting to be picked up. In this way, it is ensured that only one cardboard is picked up each time, avoiding the equipment from malfunctioning and stopping normal operation, ensuring the continuity and efficiency of production. At the same time, no manual assistance is required during the separation process, reducing labor intensity and improving the automation rate.

Detailed implementation manners

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present application.

[0028] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is usually placed when in use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0029] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0030] In the description of the embodiments of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0031] According to a first aspect of the present invention, a material taking mechanism with a function of preventing cardboard adhesion is provided, as Figures 1 to 6 shown. The material taking mechanism with a function of preventing cardboard adhesion is used for a box folding device. The box folding device may include a structural frame (not shown). The structural frame serves as the main structure of the box folding device, playing a supporting role, and can also be used for the installation of various components such as feeding, flanging, box buckling, and sliding pushing.

[0032] The material taking mechanism with a function of preventing cardboard adhesion includes a feeding component and a guiding and separating component. In the following description, the detailed structures of the feeding component and the guiding and separating component of the material taking mechanism with a function of preventing cardboard adhesion will be specifically described with reference to Figures 1 to 6 In addition, as Figure 6 shown, in the embodiment, three directions are also involved, namely the first direction S1, the second direction S2, and the third direction S3. The first direction S1 can be understood as the direction from one end to the other end of the following scraping edge limiting block 202 in the length direction, the second direction S2 can be understood as the direction from one end to the other end of the following scraping edge limiting block 202 in the width direction, and the third direction S3 can be understood as the direction from one end to the other end of the following scraping edge limiting block 202 in the height direction.

[0033] As shown Figures 1 to 3 , Figure 7 in the embodiment, the feeding assembly is used for placing the cardboard stack 3 and feeding the cardboard. The cardboard stack 3 can be formed by stacking multiple cardboard bodies 7 one on top of the other. Each time when feeding, the lifting and picking member 101 sucks one cardboard body 7 and performs the subsequent pressing and forming action. The guiding and separating assembly is arranged on the side of the feeding assembly to separate the adhered cardboard bodies 7. The guiding and separating assembly can be arranged on the side of the cardboard stack 3 as shown Figure 1 and Figure 2 so that the adhered cardboard bodies 7 are separated, ensuring that the lifting and picking member 101 sucks only one cardboard body 7 each time.

[0034] Specifically, the guiding and separating assembly includes a guiding and limiting plate 201 and a scraping edge and limiting block 202. The guiding and limiting plate 201 is used for guiding the cardboard body 7. When the lifting and picking member 101 sucks the cardboard body 7, the guiding and limiting plate 201 can limit the moving direction of the cardboard body 7, ensuring the correctness of the picking action, ensuring the feeding direction of the cardboard body 7, and facilitating subsequent operations. The scraping edge and limiting block 202 can be used to separate the adhered cardboard bodies 7. The scraping edge and limiting block 202 is arranged on the upper part of the guiding and limiting plate 201, capable of separating the adhered cardboard bodies 7. The guiding and limiting plates 201 are arranged at both the first end 301 and the second end 302 of the cardboard stack 3, so as to ensure that both ends of the cardboard body 7 can be restricted, further ensuring the correct moving direction of the cardboard body 7 without deviation. The scraping edge and limiting block 202 is located at the upper part of the cardboard stack 3. Each time when picking, the cardboard body 7 in the cardboard stack 3 needs to pass through the scraping edge and limiting block 202 to separate the adhered cardboard bodies 7.

[0035] Preferably, as shown Figure 7 in the embodiment, the folding box device including the picking mechanism with the function of preventing cardboard adhesion can be used to produce cardboard bodies 7 with specifications such as 370 mm in length and 300 mm in width. Both sides of the cardboard body 7 can include crease weak areas 701 close to and parallel to the scraping edge and limiting block 202. The crease weak areas 701 are used for bending in the subsequent box buckling process.

[0036] Thus, the number of the guiding and separating assemblies can be two groups. The two groups of guiding and separating assemblies are respectively arranged at both ends of the cardboard stack 3. Here, both ends can be understood as shown Figure 2The left and right ends shown in the figure. The distance between the two facing surfaces of the two scraping edge limit blocks 202 in the two groups of guiding and separating components is less than the distance between the first end 301 and the second end 302 of the cardboard stack 3. That is to say, it can be understood that the distance between the two scraping edge limit blocks 202 is less than the width of the cardboard body 7. Furthermore, each time when feeding, the cardboard body 7 can generate friction with the scraping edge limit blocks 202, causing the crease weak part 701 to bend. When the plurality of suction cups 103 of the lifting and picking member 101 suck out the cardboard body 7 and lift it upwards, since the cardboard bodies 7 are often adhered together due to tight stacking, when the lifting and picking member 101 sucks the topmost cardboard body 7 to the scraping edge limit blocks 202, due to the blockage of the scraping edge limit blocks 202, the cardboard body 7 bends at the crease weak part 701. At this time, due to the bending of the topmost cardboard body 7, a gap is generated between it and the adjacent cardboard body 7, and air rushes in accordingly. In this way, the topmost cardboard body 7 and the adjacent lower cardboard body 7 are separated and fall off, solving the problem of adhesion, and thus ensuring that only one cardboard body 7 is picked each time.

[0037] To sum up, the picking mechanism with the function of preventing cardboard adhesion enables the top-layer cardboard body 7 to be taken away by the feeding component through the guiding limit plate 201 and the scraping edge limit blocks 202 arranged in the guiding and separating component. During the taking-away process, due to the friction between the scraping edge limit blocks 202 and the top-layer cardboard body 7, the crease weak part 701 of the cardboard body 7 bends. Furthermore, air can rush into the space between the two adjacent cardboard bodies 7, causing the lower-layer cardboard body 7 to separate and fall, thus ensuring that only one cardboard body 7 is picked each time, without manual intervention, enabling the whole folding box device to continuously feed normally, ensuring the normal operation of the folding box device, and improving the working efficiency and automation rate.

[0038] Preferably, as Figures 1 to 3 shown, in the embodiment, the picking mechanism with the function of preventing cardboard adhesion can be switched between the stop state and the working state. When the picking mechanism with the function of preventing cardboard adhesion is in the stop state, the cardboard stack 3 is located below the scraping edge limit blocks 202, and the cardboard stack 3 does not exceed the scraping edge limit blocks 202 in the height direction. Here, the height direction can be understood as the direction from bottom to top or from top to bottom as shown in Figure 2 . When the picking mechanism with the function of preventing cardboard adhesion is in the working state, the feeding component sucks the cardboard body 7 located at the top of the cardboard stack 3, and drives the cardboard body 7 located at the top to abut and slide against the scraping edge limit blocks 202 until it separates from the scraping edge limit blocks 202, thus completing a feeding action.

[0039] Preferably, as Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, in the embodiment, the guiding and separating assembly may further include a gap adjusting member 203. One end of the gap adjusting member 203 is adjustably connected to the guiding and limiting plate 201, and the other end of the gap adjusting member 203 is adjustably connected to the structural frame. That is, it can be understood that the guiding and limiting plate 201 is mounted on the structural frame through the gap adjusting member 203. During the initial debugging of the equipment and subsequent adjustment of the equipment, the position of the guiding and limiting plate 201 can be adjusted by adjusting the mounting position of the gap adjusting member 203 on the structural frame.

[0040] Preferably, as Figure 4 shown, in the embodiment, the guiding and limiting plate 201 may be provided with threaded holes, and both ends of the gap adjusting member 203 may be provided with adjustment holes 402 formed as waist-shaped holes. The adjustment holes 402 are connected to the threaded holes through an adjusting member 401 formed as an adjusting bolt. By adjusting the positions of the adjustment holes 402 and the adjusting member 401, the position adjustment of the guiding and limiting plate 201 is realized, thereby adjusting the gap between the guiding and limiting plate 201 and the cardboard stack 3.

[0041] Preferably, as Figures 1 to 5 shown, in the embodiment, the guiding and limiting plate 201 can adjust the distance from the cardboard stack 3 through the gap adjusting member 203. Refer to Figure 3 . A certain gap is provided between the guiding and limiting plate 201 and the first end 301 or the second end 302 of the cardboard stack 3 to avoid interference. At the same time, in order to better play the role of limiting and guiding, the distance between one guiding and limiting plate 201 and the first end 301 of the cardboard stack 3 is the same as the distance between the other guiding and limiting plate 201 and the second end 302 of the cardboard stack 3 (or can be similar, and it is necessary to ensure within the range of production requirements. Those skilled in the art can make reasonable settings according to production needs).

[0042] Preferably, as Figure 1 、 Figure 5 and Figure 6 shown, in the embodiment, the edge scraping and limiting block 202 is detachably arranged on the guiding and limiting plate 201. The edge scraping and limiting block 202 is provided with a plurality of disassembly through holes 2022, and the guiding and limiting plate 201 is provided with first mounting holes 601 matching the disassembly through holes 2022, and the disassembly through holes 2022 and the first mounting holes 601 are installed through connection screws.

[0043] Preferably, in the embodiment, the edge scraping and limiting block 202 may be formed as a strip-shaped structure and made of an engineering plastic material with a low friction coefficient, such as POM (polyoxymethylene).

[0044] Preferably, as Figure 1 、 Figure 2 and Figure 6As shown, in the embodiment, since there is strong friction between the edge scraping limiting block 202 and the cardboard body 7, it often causes frictional damage or even damage to the edge of the cardboard body 7, especially the place where the cardboard body 7 touches the edge scraping limiting block 202. Therefore, the edge scraping limiting block 202 is provided with a transition fillet 2021. Specifically, the end of the edge scraping limiting block 202 facing the cardboard stack 3 is provided with a transition fillet 2021, that is, further changing the surface of the edge scraping limiting block 202 in contact with the cardboard body 7 into a rounded surface, and changing the bottom surface of the edge scraping limiting block 202 into an arc shape, and the arc surface faces the cardboard body 7. The transition fillet 2021 can enable the upper cardboard body 7 to smoothly slide over the edge scraping limiting block 202 when the lower cardboard body 7 falls, and at the same time can also play a role in protecting both ends of the cardboard body 7.

[0045] As an alternative, the bottom surface of the edge scraping limiting block 202 can also be selected in other shapes, for example, an inclined surface inclined inward can achieve the technical effect. The edge scraping limiting block 202 can also be other curved surface shapes, and its overall height gradually decreases from outside to inside. The gradually decreasing height of the edge scraping limiting block 202 can greatly reduce the rigid friction between the edge scraping limiting block 202 and the edge of the cardboard body 7.

[0046] Preferably, as Figure 6 shown, in the embodiment, the dimension of the edge scraping limiting block 202 in the first direction S1 is smaller than the dimension of the guiding limiting plate 201 in the first direction S1. This avoids interference caused by the edge scraping limiting block 202 being too long and protruding from the guiding limiting plate 201.

[0047] Preferably, as Figure 6 shown, in the embodiment, the dimension of the edge scraping limiting block 202 in the second direction S2 is 3-5 times the thickness of the cardboard body 7, and the dimension of the edge scraping limiting block 202 in the third direction S3 is 4-6 times the thickness of the cardboard body 7, so as to adapt to the specification of the cardboard body 7 and ensure the effectiveness of the separation of the cardboard body 7.

[0048] Preferably, in the embodiment, the thickness of the cardboard body 7 is 3 mm. Correspondingly, the dimension (i.e., length) of the edge scraping limiting block 202 in the first direction S1 can be 320 mm, the dimension (i.e., width) of the edge scraping limiting block 202 in the second direction S2 can be 10 mm, the dimension (i.e., height) of the edge scraping limiting block 202 in the third direction S3 can be 15 mm, and the arc chamfer radius of the transition fillet 2021 is 6 mm.

[0049] Preferably, as Figure 1 and Figure 2As shown, in the embodiment, the loading component may include a lifting and picking member 101 and a loading table 102. The lifting and picking member 101 is arranged above the loading table 102. The cardboard stack 3 is placed on the loading table 102. The guiding and limiting plates 201 are arranged on both sides of the loading table 102, and the edge scraping and limiting blocks 202 are located at the upper parts of both sides of the loading table 102. The lifting and picking member 101 may be a member including a plurality of suction cups 103 in the prior art, which is used to adsorb the cardboard body 7 and perform the loading action on the cardboard body 7.

[0050] Preferably, as Figure 1 and Figure 2 shown, in the embodiment, the loading table 102 can be used to carry the cardboard stack 3. At the same time, the loading table 102 is slidably arranged on the structural frame through the track 104. The sliding is for: after the lifting and picking member 101 takes away one cardboard body 7 each time, the overall height of the cardboard stack 3 will decrease. In order to match the lifting and picking member 101, after taking away one cardboard body 7, the loading table 102 needs to move upward correspondingly. The movement of the loading table 102 can be driven by a servo motor.

[0051] Preferably, as Figure 4 and Figure 5 shown, in the embodiment, the loading component further includes a photoelectric switch (not shown). The photoelectric switch is arranged on the guiding and limiting plate 201. The guiding and limiting plate 201 is provided with a second mounting hole 602, and the photoelectric switch is arranged in the second mounting hole 602. The setting position of the photoelectric switch is close to the setting position of the edge scraping and limiting block 202. The photoelectric switch can be used to detect whether the lifting action of the servo motor of the loading table 102 is accurately completed, so as to ensure that the cardboard body 7 is at the same height each time when picking up materials.

[0052] The working process of the material taking mechanism with the function of preventing cardboard adhesion is as follows: Stack the sorted cardboard stacks 3 on the loading table 102, adjust the guiding and limiting plates 201 on both sides according to the width of the cardboard body 7 to ensure uniform gaps on both sides of the cardboard body 7; then lift the material taking member 101 and lower it under the action of the cylinder to take the material. The suction cup 103 for taking the material presses down, adsorbs the cardboard body 7 to be folded and then lifts. When the cardboard body 7 to be folded passes through the scraping edge limiting blocks 202 on both sides, the edge of the cardboard body 7 undergoes a short deformation and bending, and at the same time, the side edge of the cardboard body 7 has a sliding friction with the scraping edge limiting blocks 202. Under the action of the lifting force, it quickly detaches from the loading table 102 and immediately returns to a flat state. Finally, when lifting the material, if the lower cardboard body 7 adheres and follows up, due to the deformation and bending of the upper cardboard body 7, a travel space gap is generated between the two adjacent adhered cardboard bodies 7, and they are no longer tightly stacked. Air enters the gap of the corresponding travel space. When the edge of the lower cardboard body 7 abuts against the scraping edge limiting block 202, due to insufficient traction force above, the lower cardboard body 7 is forcibly "pulled down" and continues to stay on the loading table 102 waiting to be extracted, ensuring the normal operation of the equipment.

[0053] The material taking mechanism with the function of preventing cardboard adhesion can realize the normal and continuous material taking of cardboard through the cooperation of the loading component and the guiding and separating component. Through the guiding and limiting plates and the scraping edge limiting blocks of the guiding and separating component, the adhered cardboard can be separated. When lifting the material, if the lower cardboard body adheres and follows up, due to the deformation and bending of the upper cardboard body, a travel space gap is generated between the two adjacent adhered cardboard bodies, and they are no longer tightly stacked. Air enters the gap of the corresponding travel space. When the edge of the lower cardboard body abuts against the scraping edge limiting block, due to insufficient traction force above, the lower cardboard body is forcibly "pulled down" and continues to stay on the loading table waiting to be extracted. In this way, it is ensured that only one cardboard is taken each time, avoiding the equipment from malfunctioning and stopping normal operation, ensuring the continuity and efficiency of production. At the same time, no manual assistance is required during the separation process, reducing the labor intensity and improving the automation rate.

[0054] In addition, according to the second aspect of the present invention, a box folding device is provided, and the box folding device includes the material taking mechanism with the function of preventing cardboard adhesion as described above. During the use of this box folding device, through the material taking mechanism with the function of preventing cardboard adhesion, it can ensure the normal and continuous movement during the material taking stage, ensuring the production progress and efficiency.

[0055] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present application, used to illustrate the technical solutions of the present application, rather than limiting it. The protection scope of the present application is not limited thereto.
