[0072] Butter paper is a very common lining in high-quality packaging boxes. Wrapping the butter paper around the product and then placing it in the box cavity can make the product moisture-proof. Figure 1 As shown, the butter paper 2 is generally connected to one end of the inner box 1 to facilitate subsequent wrapping. Due to the characteristics of the butter paper 2, the state of the end of the butter paper 2 away from the inner box 1 is in an uncontrollable state, and may be turned outward to the outside of the inner box, or may be folded inward to the top of the inner box. When the butter paper 2 is folded inward to the top of the inner box 1, it will affect the transfer, assembly and foaming of the inner box 1.

[0073] In order to prevent the inward folding of the butter paper 2 from affecting the production process, the present application discloses an assembly and foaming device for an inner box and a skin shell, which is mainly used to assemble the inner box 1 with the butter paper 2 onto the skin shell 3 after gluing.

[0074] like Figure 2 As shown, it includes a frame 10, a first transfer mechanism 20, a second transfer mechanism 30 and a bubble pressing mechanism 40.

[0075] The frame 10 serves as the supporting body of the device and can be a hollow metal frame on which a working platform is arranged.

[0076] Combination Figure 3 As shown, the frame 10 is provided with a feeding station 1a, a first positioning station 1b, a second positioning station 1c, an assembly station 1d and a bubble pressing station 1e, wherein the feeding station 1a, the first positioning station 1b and the assembly station 1d are arranged along a first direction, and the second positioning station 1c, the assembly station 1d and the bubble pressing station 1e are arranged along a second direction.

[0077] It can be understood that the first direction and the second direction are two directions on a horizontal plane that form a certain angle. In a preferred embodiment, the first direction and the second direction are perpendicular to each other. For ease of description and understanding, the corresponding Figure 1 In the position shown in the middle device, the direction from its left side to its right side is called the first direction, and the direction from its front to the rear is called the second direction, and the directions are schematically shown by arrows.

[0078] The first transfer mechanism 20 can transfer the inner box 1 from the feeding station 1a to the first positioning station 1b for positioning, and transfer the positioned inner box 1 to the assembly station 1d for assembly with the skin shell 3 to form a Figure 2 The box structure shown.

[0079] The second transfer mechanism 30 can transfer the glued skin 3 from the second positioning station 1c to the assembly station 1d, and transport the assembled box structure to the bubble pressing station 1e.

[0080] The bubble pressing mechanism 40 is arranged corresponding to the bubble pressing station 1e, and is used for pressing bubbles on the assembled box structure.

[0081] The first transfer mechanism 20 includes a first holding assembly 25 , and a second holding assembly is provided on one side of the bubble pressing station 1 e . Both the first holding assembly and the second holding assembly are used to keep the butter paper 2 in an outwardly turned state folded toward a side away from the inner box 1 .

[0082] The inner box 1 at the feeding station 1a needs to keep the butter paper turned outward before being transferred. In this example, the assembled bubble pressing device also includes an inner box feeding mechanism 50.

[0083] Specific, combined Figure 4 As shown, the inner box feeding mechanism 50 includes an inner box conveying line 51, a pushing assembly 52 and a butter paper anti-rebound assembly 53.

[0084] Among them, the inner box conveyor line 51 is arranged in the second direction, and its front end is the loading end 51a, and the rear end is the discharging end 51b. The feeding station 1a is located on the right side of the discharging end 51b, and the inner box 1 conveyed from the loading end 51a to the discharging end 51b is pre-set to an inward folded state. Specifically; in this embodiment, the inward folded state means that the butter paper 2 is located on the left side of the inner box 1 (i.e., the opposite side of the first direction), and the butter paper 2 is folded to the right (along the first direction) to the top of the inner box by manual or other pre-positioned devices before loading, and a gap is reserved between the middle arch of the butter paper 2 and the inner box 1 in a natural state.

[0085] The pushing assembly 52 is disposed on the left side of the discharging end 51 b and is used to push the inner box 1 located at the discharging end 51 b to the feeding station 1 a.

[0086] In actual implementation, in order to realize automatic material pushing, the pushing assembly 52 includes a pushing block 521 and a sensor. When the sensor senses the incoming material of the inner box 1, the pushing block 521 pushes the inner box 1 to the right to the feeding station 1a.

[0087] The butter paper anti-rebound assembly 53 includes a blocking member 531, a lever 532 and a pre-folding member 533. The blocking member 531 is arranged at the discharge end 51b, and the lever 532 is arranged at the blocking member 531 and arranged toward the feeding end 51a. When the inner box 1 moves toward the discharge end 51b, the lever 532 extends into the gap between the butter paper 2 and the inner box 1. The pre-folding member 533 is arranged on the side of the lever 532 close to the feeding station 1a.

[0088] When the pushing block 521 pushes the inner box 1 to move to the right, since the lever 532 is located in the gap between the butter paper 2 and the inner box 1, the relative movement of the lever 532 and the inner box 1 causes the lever 532 to push the butter paper, turning the butter paper 2 outside the inner box 1 and extending to the left (i.e., the opposite side of the first direction) in an outward-turned state. During the rightward movement of the inner box 1 in this state, the pre-folding piece 533 continues to keep the butter paper 2 in an outward-turned state until it enters the feeding station 1a.

[0089] like Figure 5 As shown, the first transfer mechanism 20 includes a crossbeam 21 , a first horizontal motion module 22 , a first inner box suction module 23 and a second inner box suction module 24 .

[0090] The first horizontal motion module 22 can drive the crossbeam 21 to move in the left-right direction. The crossbeam 21 is arranged in the left-right direction. The crossbeam 21 has a first material picking position and a second material picking position in its motion stroke.

[0091] The first inner box suction module 23 and the second inner box suction module 24 are installed on the beam 21 at intervals along the first direction. When the beam 21 moves from the first material picking position to the second material picking position, the first inner box suction module 23 moves from the feeding station 1a to the first positioning station 1b, and the second inner box suction module 24 moves from the first positioning station 1b to the assembly station 1d.

[0092] In this way, the effect of two inner box suction modules corresponding to three working stations is achieved. When the first inner box suction module 23 transfers the inner box 1 at the feeding station 1a to the first positioning station 1b, the second inner box suction module 24 synchronously transfers the inner box 1 at the first positioning station 1b to the assembly station 1d, ensuring the one-way formation to realize two operations and reducing the waiting time of the suction module.

[0093] Among them, Figure 6 As shown, the first inner box suction module 23 includes a first lifting drive member 231 , a first bracket 232 , and a plurality of suction rods 233 , and the first holding assembly 25 includes a first blowing block 251 .

[0094] Specifically, the first lifting drive member 231 is connected to the left end of the beam 21 and can drive the first bracket 232 to rise and fall;

[0095] A plurality of suction rods 233 are connected to the lower end of the first bracket 232 for sucking the bottom surface of the inner box 1. Preferably, the suction rods 233 are arranged at positions corresponding to the positions near both ends of the inner box 1 to ensure uniform force when sucking the inner box 1.

[0096] The first blowing block 251 is connected to the lower part of the first bracket 232 and can blow air to the left side (ie, the opposite direction of the first direction) to blow the butter paper 2 to the left side so that the butter paper 2 remains in an outward-turned state.

[0097] After the first inner box suction module 23 transfers the inner box 1 to the first positioning station 1 b , the inner box 1 is positioned.

[0098] like Figure 7 As shown, the second inner box suction module 24 includes a second lifting drive member 241 , a second bracket 242 , a material pressing member 243 , and two lateral suction components 244 , and the first holding component 25 also includes a second blowing block 252 .

[0099] The second lifting driving member 241 is connected to the right end of the beam 21 and can drive the second bracket 242 to rise and fall.

[0100] The pressing piece 243 is connected to the lower end of the second bracket 242 and is used to flatten the bottom surface of the inner box 1 .

[0101] Since the bottom area of ​​the inner box 1 is pressed by the pressing piece 243, it is no longer suitable to transfer the inner box by the bottom surface adsorption method in the inner box suction module 23. Therefore, two lateral adsorption components 244 are used here, which include a lateral driving member 2441 and a lateral suction block 2442. The two lateral driving members 2441 are connected to the two sides of the second bracket 242. The lateral driving members 2441 are connected to the lateral suction blocks 2442 one by one and can drive the corresponding lateral suction blocks 2442 to move toward or away from the second bracket 242. In this embodiment, the two lateral driving members 2441 are respectively installed at the left and right ends of the second bracket 242, and they respectively drive the corresponding lateral suction blocks 2442 to move left and right.

[0102] When the inner box 1 needs to be adsorbed, the transverse driving member 2441 first drives the two transverse suction blocks 2442 to retract to prevent pressing the side of the inner box 1. After the pressing member 243 presses the bottom surface of the inner box 1, the transverse driving member 2441 extends outward to make the outer side surfaces of the transverse suction blocks 2442 contact the left and right inner walls of the inner box 1 and adsorb.

[0103] The second blowing block 252 is connected to the lower part of the second bracket 242 and can blow air to the left side (ie, the opposite direction of the first direction) to blow the butter paper 2 to the left side so that the butter paper 2 remains in an outward-turned state.

[0104] The transfer of the inner box 1 is realized by the first transfer mechanism 20, while the transfer of the skin shell 2 is realized by the second transfer mechanism 30; Figure 8 As shown, the second transfer mechanism 30 includes a second horizontal motion module 31, a sliding seat 32, a flip module 33, a material pushing member 34 and two skin suction modules 35.

[0105] The second horizontal motion module 31 can drive the sliding seat 32 to move in the front-rear direction. The sliding seat 32 has a loading position and a discharging position in its motion stroke.

[0106] The flip module 33 includes a swing drive assembly 331 , a rotating shaft 332 and two mounting seats 333 . The rotating shaft 332 is arranged along the front-to-back direction. The two mounting seats 333 are respectively arranged at the front and rear ends of the rotating shaft. The swing drive assembly 331 is used to drive the rotating shaft 332 to rotate.

[0107] The skin suction modules 35 are arranged on the mounting seat 333 in a one-to-one correspondence, and the two skin suction modules 35 and the material pushing member 34 are arranged in sequence from front to back.

[0108] When the sliding seat 32 moves from the loading position to the discharging position, the skin suction module 35 near the rear end moves from the second positioning station 1c to the assembly station 1d, and the pushing member 34 moves from the assembly station 1d to the bubble pressing station 1e.

[0109] When the skin shell suction module 35 at the front end transfers the skin shell 3 from the previous process to the second positioning station 1c for positioning, the skin shell suction module 35 at the rear end transfers the positioned skin shell 3 to the assembly station 1d. At the same time, the pushing piece 34 pushes the assembled box body structure to the bubble pressing station 1e, thereby improving work efficiency; the flipping module 33 realizes the flipping of the two skin shell suction modules 35 through the rotation of the rotating shaft 332, thereby ensuring that the skin shell suction module 35 and the pushing piece 34 are flipped up to a certain angle during the return journey, thereby preventing the skin shell suction module 35 and the pushing piece 34 from interfering with the position of the skin shell 3.

[0110] The first positioning station 1b and the second positioning station 1c can be positioned by directly lowering them by corresponding transfer mechanisms, or by manually adjusting the positioning, or by using a separate positioning mechanism. In order to ensure the accuracy of the assembly position, this embodiment uses a positioning mechanism for positioning.

[0111] The first positioning station 1b and the second positioning station 1c are both correspondingly provided with a first positioning mechanism 60 .

[0112] Among them, Fig.10 As shown, the first positioning mechanism 60 includes a first positioning stop bar 61 and two telescopic positioning components 62;

[0113] The two first positioning bars 61 are arranged at right angles. Preferably, one of the two first positioning bars 61 is located in the front-to-back direction, and the other is located in the left-to-right direction, for blocking and positioning in the front-to-back direction or the left-to-right direction.

[0114] The telescopic positioning assembly 62 includes a first telescopic driving member 621 and a positioning plate 622. The positioning plates 622 are arranged one-to-one with respect to the first positioning bar 61. The first telescopic driving member 621 is used to drive the positioning plate 622 to move closer to or away from the corresponding first positioning bar 61. The positioning of the inner box 1 or the leather shell 3 is achieved by clamping in four directions, ensuring accurate and stable positioning.

[0115] The assembled box structure is pushed by the pushing member 34 to the bubble pressing station 1e for bubble pressing by the bubble pressing mechanism 40.

[0116] Among them, Fig. 9 As shown, the bubble pressing mechanism 40 includes a top plate 41, a fourth lifting drive member 42, a guide rod 43, a guide sleeve 44 and a bubble pressing mold 45. The top plate 41 is arranged above the bubble pressing station 1e, the guide sleeve 44 is installed on the top plate 41, the guide rod 43 is vertically inserted in the guide sleeve 44, the lower end of the guide rod 43 is connected to the bubble pressing mold 45, and the fourth lifting drive member 42 is connected to the top plate 41 and can drive the bubble pressing mold 45 to rise and fall.

[0117] During the bubble pressing process, it is particularly important to prevent the butter paper 2 from folding inwards, because once folded inwards, the butter paper 2 will be damaged when the bubble pressing mold 45 is pressed down. Therefore, in this embodiment, a large air volume suction method is used to ensure that the butter paper 2 is continuously turned outwards.

[0118] Specific, combined Fig. 9 and Fig.11 As shown, the second holding component includes a suction cylinder 71 and a guide rod 72. The suction cylinder 7 is arranged on the left side of the bubble pressing station 1e. The suction direction of the suction cylinder 71 is toward the left side. The guide rod 72 connects the assembly station 1d and the bubble pressing station 1e. The guide rod 72 includes a guide section 721 and a pressing section 722 in sequence along the front-to-back direction. The guide section 721 extends downward from the front to the back. When the box structure is transported from the assembly station 1d to the bubble pressing station 1e, the guide section 721 can guide the butter paper 2 in the everted state to the bottom of the pressing section 722. The setting of the guide section 721 and the pressing section 722 ensures that the butter paper 2 will not be folded inwards during the process of the box structure being pushed to the bubble pressing station, thereby maintaining the everted state of the butter paper 2; the suction cylinder 71 sucks the butter paper by a strong suction method to prevent the butter paper from being pressed by the bubble pressing mold 45.

[0119] More preferably, the second retaining assembly also includes an auxiliary rod 73, which connects the assembly station 1d and the bubble pressing station 1e and is located on the side of the guide rod 72 close to the bubble pressing station 1e. The auxiliary rod 73 includes an auxiliary section 731 and a top-feeding section 732 in sequence along the front-to-back direction. The auxiliary section 731 extends upwardly at an angle from front to back, and the top-feeding section 732 is located above the pressing section 722. The lower end height of the auxiliary section 731 is lower than the upper end height of the guide section 721.

[0120] Since the auxiliary section 731 extends upwardly from front to back and the guide section 721 extends downwardly from front to back and the lower end height of the auxiliary section 731 is lower than the upper end height of the guide section 721, the guide section 721 and the auxiliary section 731 form an intersection facing forward. When the box structure is transported from the assembly station 1d to the bubble pressing station 1e, the butter paper 2 enters from the intersection between the auxiliary section 731 and the guide section 721, and then passes above the top section 732 and extends from below the pressing section 722. In this way, a structure that blocks the butter paper 2 from returning to its original position is formed to prevent the butter paper 2 from rebounding.

[0121] In this embodiment, a second positioning mechanism 80 is correspondingly provided at the bubble pressing station 1e.

[0122] The second positioning mechanism 80 includes two second positioning stop bars 81 and a push angle positioning assembly 82 .

[0123] The two second positioning bars 81 are arranged at right angles. Preferably, one of the two second positioning bars 81 is located in the front-to-back direction, and the other is located in the left-to-right direction, for blocking and positioning in the front-to-back direction or the left-to-right direction.

[0124] The corner positioning assembly 82 includes a second telescopic drive member and a corner positioning member. The corner positioning member has a positioning right angle with right angle sides parallel to the two second positioning bars 81 . The second telescopic drive member is used to drive the corner positioning member to approach or move away from the right angle formed by the two second positioning bars 81 .

[0125] Through the push angle positioning of the second positioning mechanism 80, the accuracy of the bubble pressing mold 45 when pressed down can be effectively guaranteed to prevent the surrounding frame of the inner box 1 from being pressed.

[0126] It can be understood that the telescopic driving member and the lifting driving member mentioned in the embodiments of the present application are common driving structures, such as a cylinder, a hydraulic cylinder or an electric push rod, and preferably, they are all cylinders.

[0127] According to the above-mentioned assembly and pressure-pressing device for the inner box and the skin shell, a process for assembling the pressure-pressing device is proposed, such as Fig.12 Combined with Figure 1-11 As shown, the process includes the following steps:

[0128] A working path is provided, which has a feeding station 1a, a first positioning station 1b, a second positioning station 1c, an assembly station 1d and a bubble pressing station 1e, wherein the feeding station 1a, the first positioning station 1b and the assembly station 1d are arranged along the left-right direction, and the second positioning station 1c, the assembly station 1d and the bubble pressing station 1e are arranged along the front-back direction.

[0129] The inner box 1 of the feeding station 1 a is transferred to the first positioning station 1 a for positioning by the first inner box suction module 23 of the first transfer mechanism 20 .

[0130] Before entering the feeding station 1a, the inner box 1 is fed by the inner box feeding mechanism 50, so that the butter paper 2 is turned outward.

[0131] The leather shell 3 after gluing is transferred to the second positioning station 1c for positioning by the leather shell suction module 35 of the second transfer mechanism 30.

[0132] Then, the positioned leather shell 3 and the inner box 1 are sequentially transferred to the assembly station 1d through the leather shell suction module 35 and the second inner box suction module 24.

[0133] The inner box 1 and the skin shell 3 are assembled into a box body structure by the blanking of the second inner box suction module 24;

[0134] The assembled box structure is transported to the bubble pressing station 1e for bubble pressing by the pushing member 34.

[0135] The inner box 1 and the box body structure always keep the butter paper 2 turned outward during the transportation process.

[0136] The device and process provided in this embodiment arrange the feeding of the inner box 1 and the skin 3 in two independent directions, and then provide a structure to keep the butter paper in an outside-turned state when the inner box 1 is transferred and bubble-pressed, thereby ensuring that the state of the butter paper 2 is always controllable during the entire working process, and effectively preventing the butter paper 2 from being damaged during the transfer, assembly and bubble-pressing processes.

[0137] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
