Description

Technical Field

[0001] The present invention belongs to the technical field of wine box production, and particularly relates to an automatic assembly system for the base of a wine box. Background Art

[0002] Wine box production is a labor-intensive enterprise. In terms of the installation of its base, in order to meet the production line speed requirements, 8 workers are currently required on the production line. Among them, 4 workers hold the plastic base of the product with their right hands, and at the same time, each worker uses the thumb, index finger, middle finger, and little finger of the right hand to press firmly on the four sides of the plastic base of the product, so that the installation position of the base is smaller than the size of the base of the box body. Then, wait for the box body produced by the front-end process of the production line to be transported. When the box body is conveyed to the manual picking position through the assembly line, the worker uses the left hand to pick up the box body, and the right hand loads the controlled plastic base into the bottom of the box body and pushes the base into the standard position and places it in the next production process; when the assembled base box body is conveyed to the installation station of the plastic upper cover of the box body, the other 4 workers respectively place the box body upright on the production table. These 4 workers respectively pick up the plastic upper cover with their right hands and tilt it 30°, when it is inserted two-thirds into the box body, and then insert the plastic upper cover into the interior of the product box body in an upright manner and buckle it with the base. The manual tilt of 30° is to facilitate the insertion of the upper cover into the interior of the box body. The base is locked on the box body through the upper cover. At this time, the process of installing the base of the box body is completed, and at the same time, a limit groove for placing the wine bottle is also processed on the surface of the upper cover. To sum up, in the prior art, only 8 workers are required for the process of installing the base of the wine box; when the worker at the base picks up the base, a grasping force of 5 kg is required to press the base so that it can be inserted into the wine box. Each worker has to complete at least 3000 actions per day. For workers, the labor intensity exceeds the standard. When the worker at the installation of the plastic upper cover installs it, it needs to be tilted 30° and then installed. During the installation process, it is very difficult to ensure that the tilt angle is the same each time, and quality problems such as product scratching, scraping, and scuffing often occur. Moreover, when assembling the base and the upper cover, it means that the production of the wine box is almost over. At this time, due to problems with the plastic upper cover, the entire wine box will become a defective product, resulting in serious waste of production materials. In addition, the space occupied by 8 workers and the corresponding equipment is extremely large, which invisibly increases the production cost of the wine box. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the background art, and provides an automatic assembly system for the base of a wine box. This assembly system can continuously complete the assembly of the upper cover and the base of the wine box, can greatly reduce the number of workers, and at the same time can reduce the labor intensity of workers.

[0004] The purpose of the present invention is achieved through the following technical solutions:

The four-station cam divider is installed in the middle of the frame. The output shaft of the four-station cam divider is horizontally arranged. A turntable is installed on the output shaft of the four-station cam divider. Four box body molds are annularly scattered around the axis of the four-station cam divider and installed on the turntable. The box body molds are adapted to the size and contour of the wine box. The box body molds are hollow. An air suction port is provided at one end of the box body mold far from the center. The four hollow box body molds are connected to a gas source through a rotary joint. The upper cover feeding mechanism, the box body pushing mechanism, the base clamping mechanism and the finished product discharging mechanism are sequentially installed on the frame at positions corresponding to the box body molds along the rotation direction of the four-station cam divider. A corresponding upper cover conveyor belt, a box body conveyor belt, a base conveyor belt and a finished product conveyor belt are respectively provided on one side of the upper cover feeding mechanism, the box body pushing mechanism, the base clamping mechanism and the finished product discharging mechanism.

[0006] The upper cover feeding mechanism is installed below the turntable. A boss adapted to the contour of the upper cover is processed on the box body mold outside the air suction port. The upper cover feeding mechanism includes a material separating cylinder and a top cover cylinder. The top cover cylinder is installed directly below the end of the lower box body mold. The piston rod of the top cover cylinder is connected to a placing plate that moves up and down towards the boss. The upper cover conveyor belt is located on one side of the top cover cylinder. The material separating cylinder is installed on the side of the upper cover conveyor belt away from the top cover cylinder. The material separating cylinder is horizontally arranged and is used to push the upper covers conveyed by the upper cover conveyor belt onto the placing plate.

Detailed implementation

[0028] As Figure 10 shown, in this embodiment, the corresponding wine box 100 is made of plastic material. A limiting groove is machined on the inner wall of the lower part of the wine box 100. A support plate 201 is integrally formed on the top of the base 200. A limiting strip 202 extending into the limiting groove is machined on the top of the support plate 201. During installation, the support plate 201 on the base 200 is closed so that the limiting strip 202 can extend into the wine box 100. At the same time, in order to prevent the limiting strip 202 from moving out of the limiting groove, it is also necessary to connect the upper cover 300 with the base 200 and press against the support plate 201 to ensure the fixation of the base 200 and the wine box 100. In addition, a groove 301 for accommodating the wine bottle needs to be machined on the upper cover 300.

[0029] As Figures 1 to 11As shown in the figure, the automatic assembly system for the wine box base provided in this embodiment includes a frame 1, a four-station cam divider 2, a box body mold 3, an upper cover feeding mechanism 4, a box body pushing mechanism 5, a base clamping mechanism 6, and a finished product discharging mechanism 7. The four-station cam divider 2 is installed in the middle of the frame 1. The output shaft of the four-station cam divider 2 is horizontally arranged. A turntable 21 is installed on the output shaft of the four-station cam divider 2. Four box body molds 3 are annularly scattered around the axis of the four-station cam divider 2 and installed on the turntable 21. The box body mold 3 is adapted to the size profile of the wine box 100. The box body mold 3 is hollow. An air suction port 31 is provided at one end of the box body mold 3 away from the center. The four hollow box body molds 3 are connected to a gas source through a rotary joint. A pressure relief groove 33 is machined on the side wall of the box body mold 3. The upper cover feeding mechanism 4, the box body pushing mechanism 5, the base clamping mechanism 6, and the finished product discharging mechanism 7 are sequentially installed on the frame 1 at positions corresponding to the box body mold 3 along the rotation direction of the four-station cam divider 2. A corresponding upper cover conveyor belt 8, a box body conveyor belt 9, a base conveyor belt 10, and a finished product conveyor belt 11 are respectively provided on one side of the upper cover feeding mechanism 4, the box body pushing mechanism 5, the base clamping mechanism 6, and the finished product discharging mechanism 7. During the process of the four-station cam divider 2 driving the turntable 21 to rotate, the upper cover feeding mechanism 4, the box body pushing mechanism 5, the base clamping mechanism 6, and the finished product discharging mechanism 7 all complete one process of assembling the wine box base. When the turntable 21 rotates one circle, the automatic assembly of the wine box base can be completed.

[0030] The upper cover feeding mechanism 4 is installed below the turntable 21. As Figure 3 shown, a boss 32 adapted to the contour of the upper cover 300 is machined on the box body mold 3 outside the air suction port 31. The boss 32 is adapted to the contour of the bottom of the wine bottle. The purpose is to improve the connection stability with the upper cover 300. The upper cover feeding mechanism 4 includes a material dividing cylinder 41 and a top cover cylinder 42. The top cover cylinder 42 is installed directly below the end of the lower box body mold 3. The piston rod of the top cover cylinder 42 is connected with a placing plate 43 that moves up and down towards the boss 32. The upper cover conveyor belt 8 is located on one side of the top cover cylinder 42. The material dividing cylinder 41 is installed on the side of the upper cover conveyor belt 8 away from the top cover cylinder 42. The material dividing cylinder 41 is horizontally arranged and is used to push the upper cover 300 conveyed by the upper cover conveyor belt 8 onto the placing plate 43. A first sensor 44 for detecting the upper cover 300 is installed on the frame 1 on one side of the material dividing cylinder 41. The first sensor 44 provides a start signal for the operation of the material dividing cylinder 41 and the upper cover conveyor belt 8. After the upper cover 300 is pushed onto the placing plate 43, the top cover cylinder 42 extends and pushes the upper cover 300 towards the upper box body mold 3. After the upper cover 300 is adsorbed to the boss 32, negative pressure sucks the upper cover 300 at the end of the box body mold 3, completing the assembly of the upper cover 300.

[0031] The box body pushing mechanism 5 is installed on the frame 1 at the rear side of the upper cover feeding mechanism 4 in the rotation direction. AsFigure 4 As shown in the figure, the box body pushing mechanism 5 includes a first guide rail 51, a first sliding seat 52 and a first servo conveying module 53. The first guide rail 51 is arranged between the box body mold 3 and the box body conveyor belt 9 on one side of the turntable 21. A baffle 54 for limiting the wine box 100 on the box body conveyor belt 9 is installed on the first guide rail 51. The first sliding seat 52 is slidably installed on the first guide rail 51. The first servo conveying module 53 is installed on one side of the first guide rail 51 and is connected to the first sliding seat 52. A feeding push plate 55 adapted to the contour of the wine box 100 is installed on the first sliding seat 52. The first servo conveying module 53 drives the first sliding seat 52 to push the wine box 100 on the box body conveyor belt 9 towards the box body mold 3. Under the action of the pressure relief groove 33, the speed of air discharge can be accelerated, so that the wine box 100 can be smoothly and successfully installed on the box body mold 3. A second sensor 56 for detecting the wine box 100 and controlling the start and stop of the box body conveyor belt is installed on the baffle 54.

[0032] The base clamping mechanism 6 is installed above the turntable 21 on the side opposite to the upper cover feeding mechanism 4, as Figure 5 shown. The base clamping mechanism 6 includes a bracket 61, a linear guide rail 62, a grasping cylinder 64 and a jaw mold 65. The bracket 61 is installed on the frame 1 between the base conveyor belt 10 and the box body mold 3. The linear guide rail 62 is horizontally installed above the bracket 61. A slider 63 is provided on the linear guide rail 62. The grasping cylinder 64 is vertically installed above the slider 63. The jaw mold 65 is slidably installed on the outer wall of the grasping cylinder 64. The jaw mold 65 is connected to the bottom end of the piston rod of the grasping cylinder 64. The jaw mold 65 is used to grasp the base 200 and apply a pre-tightening force to the loading end of the base 200. The loading end of the base 200 is one end of the support plate 201 on which the limit strip 202 is installed on the base 200. A third sensor 66 for detecting the base 200 is installed on the base conveyor belt 10. The third sensor 66 provides a reference signal for the start and stop of the base conveyor belt 10 and the grasping of the base 200 by the base clamping mechanism 6. As Figures 6 to 8As shown, the jaw die 65 includes a jaw base 651, a jaw table 652, a jaw cylinder 653, a frustum 654, a spring ejector rod 655, and a clamping plate 656. The jaw base 651 is slidably mounted on the side wall of the grasping cylinder 64. The piston rod of the grasping cylinder 64 is connected to the jaw base 651, and the grasping cylinder 64 drives the jaw base 651 to move up and down in the vertical direction. A jaw table 652 is fixedly connected to the bottom of the jaw base 651. A tapered hole 657 with a larger upper part and a smaller lower part is machined on the jaw table 652. The jaw cylinder 653 is vertically mounted on the jaw base 651. The frustum 654 is connected to the extending end of the jaw cylinder 653 and is pushed into the tapered hole 657 by the jaw cylinder 653. The four clamping plates 656 are evenly hinged on the outer side wall of the jaw base 651. A stepped hole 658 communicating the clamping plate 656 and the frustum 654 is provided on the jaw base 651 above the hinge. The large-diameter end of the stepped hole 658 faces the tapered hole 657. The spring ejector rod 655 is installed in the stepped hole 658. When the frustum 654 enters the tapered hole 657, it pushes the spring ejector rod 655 to cause the four clamping plates 656 to contract inward and clamp the base 200. When releasing the base 200, the jaw cylinder 653 drives the frustum 654 out of the tapered hole 657. At this time, the spring ejector rod 655 contracts towards the tapered hole 657, the clamping plate 656 is not stressed, and the stepped hole 658 can prevent the spring ejector rod 655 from falling off.

[0033] The finished product out-box mechanism 7 is installed on the frame 1 on the side opposite to the box body pushing mechanism 5, as Figure 9As shown in the figure, the finished product out-box mechanism 7 includes a second guide rail 71, a second sliding seat 72, a second servo conveying module 73, an out-box cylinder 74, an out-box suction cup 75 and an out-box pressing plate 76. The second guide rail 71 is horizontally installed between the box body mold 3 and the finished product conveyor belt 11 on the other side of the turntable 21. The second sliding seat 72 is slidably installed on the second guide rail 71. The second servo conveying module 73 is installed on one side of the second guide rail 71 and is connected to the second sliding seat 72 to drive the second sliding seat 72 to move on the second guide rail 71. The out-box cylinder 74 is vertically installed on the side wall of the second sliding seat 72 close to the box body mold 3. The out-box suction cup 75 is horizontally installed on the piston rod of the out-box cylinder 74. The out-box pressing plate 76 is connected to the second sliding seat 72. The end of the out-box pressing plate 76 is processed with an out-box pressing plate 76 adapted to the contour of the bottom plate. The out-box pressing plate 76 faces the bottom of the wine box 100, and the out-box suction cup 75 faces the side wall of the wine box 100. During the process of the second servo conveying module 73 driving the second sliding seat 72 to move towards the box body mold 3, the out-box pressing plate 76 first pushes the base 200 into place and cooperates with the box body mold 3 to press the upper cover 300 into place to complete the assembly of the base 200. Subsequently, the out-box suction cup 75 adsorbs to the outer wall of the wine box 100 under the action of the out-box cylinder 74, and then drags the wine box 100 outwards onto the finished product conveyor belt 11. In order to prevent the out-box suction cup 75 from adsorbing to the box body mold 3, there are two pressure relief grooves 33, and the two pressure relief grooves 33 are aligned with the adsorption position of the out-box suction cup 75. In this way, when there is no wine box 100 on the box body mold 3, it will not cause the finished product out-box mechanism 7 to adsorb to the box body mold 3.

[0034] The usage method of the present invention is as follows:

[0035] (1) First, connect the power supply and air source of the equipment. The rotary joint of the box body mold 3 needs to be connected to the negative pressure end of the compressor, and the rest of the pneumatic components are connected to the positive pressure end of the compressor.

[0036] (2) Then, one staff member places the base 200 and the upper cover 300 on the corresponding upper cover conveyor belt 8 and base conveyor belt 10, and the wine box 100 is conveyed from the upstream wine box 100 production line.

[0037] (3) After the first sensor 44 at the upper cover feeding mechanism 4 detects the upper cover 300, the material distributing cylinder 41 pushes the upper cover 300 to the placing plate 43 of the top cover cylinder 42. When the material distributing cylinder 41 extends, the upper cover conveyor belt 8 pauses. After the material distributing cylinder 41 retracts, the upper cover conveyor belt 8 moves the lower upper cover 300 to the extended end of the material distributing cylinder 41 and then pauses. Subsequently, the top cover cylinder 42 drives the upper cover 300 towards the box body mold 3. After the top cover cylinder 42 moves in place, the boss 32 of the box body mold 3 extends into the groove of the upper cover 300. At the same time, the suction pipe is connected to the negative pressure pipeline to adsorb the upper cover 300 at the end of the box body mold 3. Then the top cover cylinder 42 resets and waits for the material distributing cylinder 41 to push the next upper cover 300 to the placing plate 43.

[0038] (4) After the box body mold 3 adsorbs the upper cover 300, the four-station cam divider 2 drives the box body mold 3 to hold the upper cover 300 and rotate clockwise by 90°, waiting for the wine box 100 processed by the upstream production line to be conveyed. At this time, the first servo conveying module 53 drives the first slide 52 to move to one end of the first guide rail 51 away from the box body mold 3. The wine box 100 is conveyed along the box body conveyor belt 9 to the baffle 54. After the second sensor 56 detects the wine box 100, the box body conveyor belt 9 pauses. At the same time, the first servo conveying module 53 drives the first slide 52 to move towards the box body mold 3. At this time, the incoming material pushing plate 55 on the first slide 52 pushes the wine box 100 towards the box body mold 3, so that the upper cover 300 and the box body mold 3 enter the box body in sequence from the top of the wine box 100. Then the first slide 52 drives the incoming material pushing plate 55 to return to the original position, and the box body conveyor belt 9 continues to work, conveying the next wine box 100 to the baffle 54.

[0039] (5) When the second sensor 56 detects that the incoming material pusher plate 55 on the first sliding seat 52 is reset, the turntable 21 rotates clockwise by 90° again. At this time, the base clamping mechanism 6 on the base clamps a base 200 on the base conveyor belt 10 and installs it on the wine box 100. When the base 200 is clamped, after the third sensor 66 detects the base 200, the base conveyor belt 10 pauses. Subsequently, the linear guide rail 62 drives the gripping cylinder 64 to move towards the base conveyor belt 10 through the slider 63. After reaching the position, the gripping cylinder 64 drives the jaw die 65 to move towards the base 200, and the base 200 is clamped by the jaw die 65. When the jaw die 65 clamps the base 200, the gripping cylinder 64 drives the jaw seat 651 to contact the upward bottom surface of the base 200. Subsequently, the clamping cylinder 653 extends, driving the conical platform 654 to extend into the conical hole 657 of the base 200. After the conical platform 654 enters the conical hole 657, it pushes the spring ejector rod 655 to extend outwards in all directions. When the spring ejector rod 655 extends, it drives the clamping plate 656 to rotate around the hinge. The four clamping plates 656 rotate simultaneously, causing the clamping plates 656 below the jaw seat 651 to close and clamp the side wall of the base 200. At the same time, it presses the facing support plate, causing the outward protruding limit strips on the support plate to converge, so that the base 200 can smoothly extend into the wine box 100. After the jaw die 65 clamps the base 200, the gripping cylinder 64 retracts, and the linear guide rail 62 drives the gripping cylinder 64 to move towards the box body die 3. When the gripping cylinder 64 moves to the specified position, the base 200 is directly above the box body die 3. Subsequently, the gripping cylinder 64 extends, and the base 200 is placed into the wine box 100. When the base 200 is placed to 30% of the installation depth, the clamping cylinder 653 retracts. At this time, the spring ejector rod 655 is not squeezed by the conical platform 654 and retracts into the jaw seat 651, and the clamping plate 656 releases the base 200. Then the gripping cylinder 64 retracts and moves above the base conveyor belt 10 again, waiting to clamp the next base 200. Installing the base 200 by 30% can prevent the clamping plate 656 from getting stuck on the wine box 100, and at this time, the support plate and the limit strips have extended into the wine box 100, and gently pushing the base 200 can make the base 200 installed in place.

[0040] (6) After the base 200 is installed, the turntable 21 rotates clockwise by 90° and moves to the finished product out - of - box mechanism 7. At this time, the second servo conveying module 73 drives the second sliding seat 72 to move along the second guide rail 71 towards the box body die 3. The out - of - box pressing plate 76 on the second sliding seat 72 pushes the base 200 to be installed in place, and then continues to move to cooperate with the box body die 3 to install the upper cover 300 on the base 200, thus completing the final forming and assembly of the base 200. Subsequently, the out - of - box cylinder 74 drives the out - of - box suction cup 75 to adsorb on the outer wall of the wine box 100. Then the second servo conveying module 73 drives the second sliding seat 72 to retract, removes the wine box 100 equipped with the base 200 from the box body die 3, and places the wine box 100 on the finished product conveyor belt 11 to be transported to the next working station.

[0041] Repeating the above steps can automatically and continuously complete the assembly of the base 200. At the finished product outbox mechanism 7, if there is no wine box 100, the outbox suction cup 75 will contact the pressure relief groove 33 of the box body mold 3, preventing the outbox suction cup 75 from sucking the box body mold 3 and ensuring the stability of the assembly system operation. At the same time, the pressure relief groove 33 can expel the air in the wine box 100 during the installation of the wine box 100, improving the speed and stability during the assembly of the wine box 100.

[0042] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solutions and inventive concepts provided by the present invention should be covered within the protection scope of the present invention.
