[0050] Some wine box packaging is to first process the barrel box, and then stick the cover plate and the surrounding strip on the inner wall of the barrel box to form a complete barrel box with a swing cover structure. In the existing barrel box surrounding strip assembly process, the cover plate is generally first attached downward to the box body, and then the surrounding strip is attached. Two attaching devices with different structures need to be operated successively, with many operating procedures, and the corresponding attaching device has limited space and is not easy to operate, which affects production efficiency. In view of this, the present invention provides a barrel box mouth assembly method, a surrounding strip forming device, and a barrel box mouth assembly device. Figures 1 to 3 The figure is a flow chart of the barrel box mouth assembly method proposed by the present invention. Figures 4 to 7 This is a schematic diagram of an embodiment of the barrel box opening assembly device proposed by the present invention. Figures 8 to 9 A schematic diagram of another embodiment of the barrel box mouth assembly device proposed by the present invention.

[0051] Please refer to Figures 1 to 3 The barrel box mouth assembly method comprises the following steps:

[0052] S10, transferring the pre-glued assembly to the bending station;

[0053] Please note that, please refer to Figure 2 The assembly includes a surrounding strip and a cover plate adhered to the middle of the surrounding strip. The adhesive is applied to the corresponding part of the assembly to facilitate direct adhesion, avoiding the situation where the space in the barrel box is small and it is difficult to apply glue.

[0054] S20, bending two side ends of the surrounding strip in the assembly on the bending station into shape;

[0055] In the natural state, the surrounding strips in the combination are in an unfolded state. At this time, the length of the surrounding strips is greater than the box mouth size of the barrel box, and it is impossible to adhere directly. It is convenient to fit after bending, and the surrounding strips are arranged in three sections, which are respectively adhered to the three inner wall surfaces adjacent to the barrel box and are matched by bending.

[0056] S30, transferring the bent and formed assembly to an assembly station so as to be fitted correspondingly to the box opening of the barrel box at the assembly station.

[0057] In the technical solution of the present invention, the pre-glued assembly is first bent and formed at the bending station to form the side ends of the surrounding strips, and the relative positions of the barrel box and the assembly are adjusted at the assembly station, so that the corresponding glue-coated part of the assembly is fixedly fitted with the inner wall surface of the barrel box, completing the assembly process of the barrel box mouth. In the bending process, both side ends of the surrounding strip are bent downward to form a shape that is conducive to being inserted, making the assembly difficulty of the surrounding strip and the box mouth lower; the cover plate is bonded to the upper wall surface of the barrel box, and the two side ends of the surrounding strip are bonded to the corresponding side wall surface of the barrel box, so that the space is reasonably used, making the assembly process of the barrel box mouth more convenient and improving production efficiency.

[0058] Furthermore, before step S30, the following steps are also included:

[0059] The barrel box to be assembled is transferred to the assembly station.

[0060] It should be noted that this step moves the barrel box to a position adjacent to the assembly. Since there is still a certain gap between the barrel box and the assembly after the movement, it can prevent interference between the assembly after it is transferred to the assembly station. In addition, this step can be performed simultaneously with step S10 to save the overall time spent on the process.

[0061] Specifically, step S30 includes:

[0062] S31, moving the barrel box to the assembly station, and adjusting the position of the barrel box so that the assembly at least partially enters the barrel box;

[0063] S32, unfolding two side ends of the surrounding strip in the assembly to make them fit with the corresponding inner wall surface of the barrel box.

[0064] It should be noted that the two side ends of the surrounding strip bent in the previous step are unfolded, and the surrounding strip and the cover plate are adhered to the corresponding inner wall surface of the barrel box. The cover plate and the surrounding strip can be adhered simultaneously or sequentially, which is not limited in the present invention.

[0065] In order to improve production efficiency, in this embodiment, after step S31, the following steps are further included:

[0066] While the barrel box and the assembly at the assembly station are correspondingly attached, another pre-glue-coated assembly is transferred to the bending station.

[0067] Such a setting can shorten the waiting time of the equipment, make the processes compact, save the turnover time between processes, and thus improve the efficiency of batch production.

[0068] The following is a preferred implementation structure according to this method.

[0069] For details, please refer to Figures 4 to 7 The barrel box mouth assembly device 1000 includes a machine base, a strip forming device 100 and a barrel box transfer component 200. The machine base has a bending station and an assembly station arranged at intervals along the front-to-back direction; the transfer table 1 of the strip forming device 100 is rotatably installed on the machine base, so that the bending component of the strip forming device 100 switches back and forth between two stations and is located at the bending station. The barrel box transfer component 200 is arranged on the machine base and is spaced apart from the strip forming device 100. The barrel box transfer component 200 includes an adsorption structure or a clamping structure having an active stroke close to the assembly station. The adsorption structure 201 or the clamping structure is used to adsorb or clamp the bottom of the barrel box and feed it into the assembly station. Specifically, in this embodiment, the two ends of the strips protruding from the cover plate in the combination are bent by the strip forming device 100, and are transferred from the bending station to the assembly station, and the adsorption structure 201 drives the barrel box to move, thereby realizing the change of the position of the barrel box, so as to complete the assembly of the combination and the barrel box at the assembly station.

[0070] For details, please refer to Figure 5 The strip forming device 100 includes a transfer platform 1, a bending assembly and a driving assembly. The transfer platform 1 can be rotatably installed to the machine base along an axis extending in an upward and downward direction. The bending assembly includes a carrying plate 21 and two folding plates 22 located on the left and right sides of the carrying plate 21. The carrying plate 21 is fixedly installed on the transfer platform 1, and the opposite side ends of the two folding plates 22 can be rotated along the axis in the length direction of the transfer platform 1 to drive the side ends of the two folding plates 22 that are away from each other to swing up and down. The two folding plates 22 have an initial position in which the upper end surfaces are flush with the upper end surface of the carrying plate 21, and the side ends of the two folding plates 22 that are away from each other swing downward to a bending position in which the carrying plate 21 is set at an angle; the driving assembly is arranged on the transfer platform 1, and is used to drive the folding plates 22 to switch between the initial position and the bending position.

[0071] In the technical solution of the present invention, the combination is transferred from the front workstation, and the two folding plates 22 are in the initial position. At this time, the cover plate in the combination is placed on the carrying plate 21, and the two side ends of the surrounding strip are placed on the two folding plates 22. The two folding plates 22 are driven by the driving assembly to transfer from the initial position to the bending position. At this time, the two folding plates 22 drive both ends of the surrounding strip to bend downward, so that the two ends of the surrounding strip are set at an angle with the cover plate. The combination is driven from the bending station to the assembly station by rotating the transfer platform 1, which occupies a small space and can adapt to the conversion between stations in different directions, is easy to set up, and improves production efficiency.

[0072] Specifically, the two folding plates 22 can be driven to move to bend the fence strips, and then the transfer platform 1 can be rotated to switch the workstations. The fence strips can also be bent while the transfer platform 1 switches the workstations, thereby compressing the production cycle. The present invention does not impose any limitation on this.

[0073] In order to ensure the synchronous movement of the surrounding strips and the folding plates 22, in one embodiment of the present invention, at least one vacuum suction cup 221 is provided on the upper end surface of each folding plate 22 to adsorb and fix the corresponding side end of the surrounding strips. After the assembly enters the bending station, the vacuum suction cup 221 works to firmly adsorb the surrounding strips until the assembly is attached, and then the vacuum suction cup 221 stops working to facilitate the complete separation of the bending assembly from the barrel box.

[0074] In this embodiment, the carrier plate 21 is arranged horizontally, and the driving assembly includes a mounting seat 311 and a gear and rack assembly corresponding to the folding plate 22. The gear and rack assembly is arranged on the mounting seat 311, the rack 3131 is meshed with the gear 312, the gear 312 is connected to the folding plate 22, and the rack 3131 is driven by the power source to move repeatedly. Figure 6The mounting seat 311 is fixedly mounted to the upper end surface of the transfer platform 1 and is spaced apart from the carrying plate 21 in the front-to-back direction. The gear 312 is rotatably mounted on the mounting seat 311 along an axis extending in the front-to-back direction. The rack is arranged on a movable plate 313, and the movable plate 313 can be movably mounted on the mounting seat 311 in the left-right direction. The driving assembly also includes a connecting member, which is located between the gear 312 and the corresponding folding plate 22 to connect the gear 312 and the folding plate 22. Specifically, the connecting member includes a first connecting rod 3141, which extends in the front-to-back direction. One end of the first connecting rod 3141 is fixedly connected to the side end of the corresponding folding plate 22 close to the carrying plate 21, and the other end is fixedly connected to the middle part of the gear 312. The movable plate 313 moves relative to the mounting seat 311, thereby driving the rack 3131 to move. Since the gear 312 is meshed with the rack 3131, after the two move relative to each other, the gear 312 rotates, and the connecting member rotates along with it, thereby driving the corresponding side end of the folding plate 22 to rotate, realizing a swinging motion state, and the transmission of the driving force is stable.

[0075] Furthermore, the mounting seat 311 is connected to the transfer platform 1 via a screw rod so that the distance between the two driving components can be adjusted, thereby improving the versatility and adjustment flexibility of the equipment.

[0076] Furthermore, the mounting seat 311 is provided with a first slide rail 3111 along one side in the length direction of the transfer platform 1, the first slide rail 3111 extends in the left-right direction, and the movable plate 313 is provided with a first slide groove corresponding to the first slide rail to slide with the first slide rail. The matching form of the slide rail and the slide groove has a simple structure and good guiding performance.

[0077] Furthermore, in this embodiment, a driving cylinder 315 is provided as a power source of the rack 3131, the driving cylinder 315 is fixedly mounted on the transfer platform 1, and the cylinder rod of the driving cylinder 315 extends in the left and right directions and is fixedly connected to the movable plate 313. The movable plate 313 is driven to move linearly by the extension and retraction of the cylinder rod, and the driving cylinder 315 can be provided simultaneously with the first slide rail and the first slide groove to ensure a linear motion with stable formation.

[0078] Moreover, in the present embodiment, two bending assemblies are provided, and the two bending assemblies are spaced apart in the front-to-back direction, and two driving assemblies are provided correspondingly. In this way, when the transfer platform 1 rotates to switch the workstation, it is ensured that the assembly is placed on both bending devices. When one of the bending assemblies bends the fence and switches to the assembly workstation driven by the transfer platform 1, the previous process can prevent another pre-glued assembly from being placed on the vacant bending assembly, thereby making the production rhythm more compact and improving production efficiency. It should be noted that in the process of the bending assembly switching back to the bending workstation from the assembly workstation, it is necessary to pay attention to switching the two folding plates 22 from the bending position back to the initial position to ensure the stable placement of each assembly.

[0079] In addition, the up and down sliding of the base is achieved by the cooperation of the slide rail, the slide groove and the cylinder. The adsorption structure 201 has an adsorption function and can slide relative to the base as a whole, thereby realizing the position change of the barrel box in the up and down directions and the front and back directions.

[0080] Furthermore, in order to keep the assembly and the barrel box in a relatively stable state during the bonding process, please refer to Figure 7 The barrel box mouth assembly device 1000 further includes a clamping and positioning assembly 300 located between the barrel box transfer assembly 200 and the surrounding strip forming device 100. The clamping and positioning assembly 300 includes a fixed seat 301 and two clamping plates 302. The fixed seat 301 is movably mounted on the machine base along the front-back direction; the two clamping plates 302 are spaced apart on the fixed seat 301 along the left-right direction. Both the clamping plates 302 can move along the left-right direction, and the opposite sides of the two clamping plates 302 are used to clamp the corresponding sides of the barrel box together. In this way, the barrel box is clamped and fixed, and at the same time, a supporting force can be provided from the outside during the folding and closing of the two folding plates 22 to ensure the stability of the fit.

[0081] The present invention does not limit the driving method of the two clamps 302. Two relatively arranged cylinders can be respectively set, and the cylinder rods of the two cylinders move toward each other. By synchronously controlling the two cylinders, the two clamps 302 can move toward each other to clamp the outer surface of the barrel box.

[0082] Furthermore, the machine base is provided with two second slide rails extending along the length direction of the transfer platform 1, and the two second slide rails are arranged at intervals. A second slide groove is correspondingly arranged on the fixed seat 301 to achieve the sliding fit of the fixed seat 301. Before the formed circumference strip-barrel cover assembly rotates to this station, the two second slide rails move backwards; when the formed circumference strip-barrel cover assembly rotates to this station, the barrel box is first pushed by the barrel box transfer assembly 200, and the barrel mouth is sleeved on the periphery of the circumference strip-barrel cover assembly, and then the two splints 302 move toward the barrel box mouth under the drive of the second slide rail module, and the splints 302 are extended to align with the barrel box mouth to support the barrel box mouth from the periphery, and then the inner bending assembly rotates in the opposite direction, and the two side ends of the circumference strip open and adhere to the inner wall of the barrel box mouth.

[0083] In another embodiment of the barrel box mouth assembly device 1000, please refer to Figure 8 In this embodiment, the carrier plate 21 includes a first plate segment 21a and a second plate segment 21b located on one side of the first plate segment 21a. The first plate segment 21a extends horizontally for placing the fence strips. The second plate segment 21b is tilted from bottom to top along the front-back direction. The two second plate segments 21b are used to raise the edge of the cover plate. At the same time, a vacuum suction cup 221 is arranged on the folding plate 22. When the assembly is transferred from the previous process to the present device, the middle section of the cover plate naturally tilts along the second plate segment 21b. The two ends of the fence strips are fixed by adsorption to the corresponding folding plates 22. The part of the fence strips that fit the cover plate is placed on the first plate segment 21a, which is convenient for positioning through the fence strips.

[0084] Please refer to Fig. 9In this embodiment, two driving components are provided corresponding to the two folding plates 22, each of the driving components includes a mounting seat 311, a gear 312, a movable plate 313 and a connecting piece. The mounting seat 311 is fixedly installed to the upper end surface of the transfer platform 1, and is spaced apart from the supporting plate 21 in the front-to-back direction. The gear 312 is rotatably installed on the mounting seat 311 along the axis extending in the front-to-back direction; the movable plate 313 can be movably installed on the mounting seat 311 in the left-right direction, and the upper end surface of the movable plate 313 is provided with a rack 3131 corresponding to the gear 312, and the rack 3131 is meshed with the gear 312; the connecting piece is located between the gear 312 and the corresponding folding plate 22, and is used to connect the gear 312 and the folding plate 22. Specifically, an arc-shaped hole is provided on the mounting plate; the gear 312 and the corresponding folding plate 22 are connected by a second connecting rod 3142 and a third connecting rod 3143, the second connecting rod 3142 is fixedly connected to the gear 312 and extends along the diameter direction of the gear 312, one end of the third connecting rod 3143 is fixedly installed on the second connecting rod 3142, and the other end passes through the arc-shaped hole and is fixedly connected to the side end of the corresponding folding plate 22 away from the supporting plate 21. The movable plate 313 moves relative to the mounting seat 311, thereby driving the rack 3131 to move. Since the gear 312 is meshed with the rack 3131, after the two move relative to each other, the gear 312 rotates, and the third connecting rod 3143 rotates accordingly. At this time, the third connecting rod 3143 swings along a circular curve, thereby driving the corresponding side end of the folding plate 22 to rotate. It should be noted that in order to ensure that the opposite side ends of the two folding plates 22 are always maintained at the same level as the first plate section 21a, the opposite side ends of the two folding plates 22 are hingedly mounted on the mounting seat 311, and the side ends of the two folding plates 22 are swung away from each other, thereby realizing the bending of the surrounding strip.

[0085] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
