Description

Technical Field

[0001] The present invention relates to the technical field of automated assembly equipment, and in particular to an automated device for assembling a bottle sleeve for a bottle liner made of a degradable material and an operating method thereof. Background Art

[0002] PEF (polyethylene 2,5-furandicarboxylate) is a 100% plant-based, recyclable and biodegradable polymer with a wide range of applications such as packaging, textiles, films, etc.

[0003] PBS (polybutylene succinate) is a biodegradable polyester material with good physical and chemical properties and a wide range of applications. PBS has good thermal and mechanical processing properties. Its melting point is between 115-120°C, its glass transition temperature is around -30°C, its tensile strength is generally between 40-50MPa, and its elongation at break is about 200-300%, showing excellent mechanical properties. In addition, PBS has a low water absorption rate and good moisture resistance. The main application areas of PBS include packaging materials, agricultural films and textiles. In terms of packaging materials, PBS is used to make disposable tableware, shopping bags and food packaging, which can be naturally degraded after use to reduce environmental pollution. In terms of agricultural films, PBS is used for ground films and covering films, which can be naturally degraded after use in farmland to reduce soil pollution. In addition, PBS is also used to make biodegradable fibers to meet the needs of green textiles. The production methods of PBS mainly include chemical synthesis and biological synthesis. The chemical synthesis method polymerizes butanediol and succinic acid through melt polycondensation, while the biosynthesis method uses microbial fermentation technology to produce PBS, which has the advantage of using renewable resources. The environmental protection characteristics of PBS make it play an important role in sustainable development. Its biodegradability allows the product to be naturally decomposed in the environment, eventually forming carbon dioxide and water, avoiding pollution.

[0004] They perfectly combine environmental characteristics with excellent functions, showing improved barrier properties to CO2 and O2, thus extending the shelf life of packaged products. PBS also has high mechanical strength, and can be injection molded into bottle sleeve products, which can then be assembled onto commonly used bottle liners and biodegradable materials such as PBS as the outer layer to meet environmental protection requirements and the mechanical strength and sealing of the bottle itself. Traditional processes generally achieve the assembly of bottle sleeves and bottle liners through cold assembly, but during the assembly process, it is necessary to solve the problem of being unable to assemble due to easy deformation of materials, which places high requirements on equipment design, is difficult, and has high requirements on equipment compatibility. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] refer to Figure 1 , PEF (polyethylene 2,5-furandicarboxylate) is a 100% plant-based, recyclable and biodegradable polymer with a wide range of applications, such as packaging, textiles, films, etc. It perfectly combines environmental characteristics with excellent functions, showing improved barrier properties to CO and O, thereby extending the shelf life of packaged products. PEF also has high mechanical strength and can be injection molded into bottle sleeve products, and then assembled onto the commonly used bottle liner 21 as an outer layer, meeting environmental protection requirements and the mechanical strength and sealing of the bottle itself. Figure 1 It is illustrated that in the present application, the bottle jacket material is divided into a bottle shoulder jacket 22, a bottle body jacket 23 and a bottle bottom jacket 24 according to different parts of the corresponding bottle liner 21, and the bottle liner 21, the bottle shoulder jacket 22, the bottle body jacket 23 and the bottle bottom jacket 24 are assembled and combined to form a bottle liner 21 with a bottle body jacket, that is, the output product 20.

[0049] Combined with reference Figure 2 and Figure 3 The present application provides an automated device 10 for bottle outer covers, and the mechanical automated process control of the automated device 10 is used to sequentially sleeve and assemble a bottle outer cover made of biodegradable materials such as PBS on the bottle liner 21 to meet environmental protection requirements. The automated device 10 includes an operating table 11, a loading mechanism 12, and a discharging mechanism 13. The operating table 11 provides processing positions for processing operations on the bottle outer covers at various locations, the loading mechanism 12 is used to transfer various raw materials to the processing positions corresponding to the operating table for processing and assembly, and the discharging mechanism 13 is used to export the processed and assembled discharging products 20 out of the operating table 11 to facilitate subsequent sorting and packaging.

[0050] Combined with reference Figure 3 and Figure 4The operating table 11 is provided with a rotatable turntable 100, and a plurality of spaced positioning devices 200 are provided on the upper surface of the turntable 100 along the circumferential direction. The turntable 100 can drive the positioning devices 200 to rotate to different processing positions. The feeding mechanism 12 includes a bottle liner conveying unit 300, a bottle shoulder conveying unit 400, a bottle body conveying unit 500 and a bottle bottom conveying unit 600 spaced along the side circumferential edge of the turntable 100. The bottle liner conveying unit 300 is used to convey the bottle liner 21 to the turntable 100 and install it on the positioning device 200; the bottle shoulder conveying unit 400 is used to convey the bottle shoulder sleeve 22 to the corresponding positioning device 200 of the turntable 100 and buckle it on the outer side of the upper body of the bottle liner 21; the bottle body conveying unit 500 is used to convey the bottle body sleeve 23 to the corresponding positioning device 200 of the turntable 100 and buckle it on the outer side of the lower body of the bottle liner 21; the bottle bottom conveying unit 600 is used to convey the bottle bottom sleeve 24 to the corresponding positioning device 200 of the turntable 100 and buckle it on the bottom of the bottle liner 21. The discharging mechanism 13 includes a discharging unit 700, which is arranged on the side of the turntable 100 and between the bottle bottom conveying unit 600 and the bottle liner conveying unit 300, and the discharging unit 700 is used to guide the discharging product 20 from the turntable 100. Here, the operating table 11 uses a high-precision stator separator for precise rotation and positioning, and cooperates with a servo motor and a positioning tooling processing and assembly process. The high-precision stator separator and the servo motor have the advantages of high precision and high response speed, which can well control the rotation of the turntable 100 on the operating table 11, and enable the positioning device 200 to accurately align each loading unit and the unloading unit 700.

[0051] Preferably, in combination with reference Figure 4 and Figure 5In one embodiment, the positioning device 200 includes a plurality of outer ring positioning grooves 210 and inner ring positioning grooves 220 of opposite numbers. At each station corresponding to the positioning device 200, one outer ring positioning groove 210 is aligned with one inner ring positioning groove 220 along the radial direction of the turntable 100, and the outer ring positioning groove 210 is closer to the edge of the turntable 100 than the inner ring positioning groove 220. The plurality of outer ring positioning grooves 210 are used to place the bottle liner 21 upright and to process and assemble the bottle liner 21 with various parts of the bottle jacket (bottle shoulder sleeve 22, bottle body sleeve 23, bottle bottom sleeve 24); the inner ring positioning groove 220 is used to place the bottle liner 21 upright and switch the processed products at different stations to the next station as the turntable rotates, so as to facilitate further assembly processing. Here, the bottle liner 21 is in an upright position during the entire process of processing and assembling the bottle outer shell. Due to the thin upper part and thick lower part of the bottle liner 21, it is more stable to be upright on the positioning device 200. The process of processing and assembling the bottle outer shell is not easy to shake and cause errors such as assembly misalignment, thereby improving the yield of the discharged product 20. It should be noted that in other embodiments of the present application, the positioning device 200 can also be a single-circle station or a multi-circle station. Whether it is a double-circle station is not limited. It only needs to realize the station state embodiment of the entire bottle outer shell assembly process.

[0052] Preferably, in combination with reference Figure 5 and Figure 6 In one embodiment, the outer ring positioning groove 210 and the inner ring positioning groove 220 have the same shape, and both include a base 211, a first clamping seat 212 and a second clamping seat 213. The base 211 is fixed on the turntable 100, and the first clamping seat 212 and the second clamping seat 213 are both fixed on the base 211 and enclosed to form a mounting groove 214. The mounting groove 214 is used to place the bottle liner 21 and the processed products. The radial dimension (width) of the mounting groove 214 is not less than the radial dimension of the bottle body sleeve 23, so that the bottle liner 21 and the related processed products can be accommodated in the mounting groove 214; the depth (height) of the mounting groove 214 is not greater than the height dimension of the lower half of the bottle liner 21, so that the upper half of the bottle liner 21 is completely exposed in the mounting groove 214. This facilitates the processing and assembly of the bottle shoulder sleeve 22. The form of the above-mentioned mounting groove 214 facilitates the processing and formation of the outer ring positioning groove 210 and the inner ring positioning groove 220. In other embodiments, the mounting groove 214 can also be directly punched, so in the present application, the formation method of the mounting groove 214 is not limited. The processing and formation method of the mounting groove 214 here can be formed by injection molding with the lower half of the discharge product 20 as the mold.

[0053] Preferably, in combination with reference Figure 5 and Figure 7In one embodiment, the bottle shoulder conveying unit 400 is provided with a first shoulder clamp 410 and a second shoulder clamp 420, and the bottle shoulder sleeve 22 includes a left shoulder sleeve 22a and a right shoulder sleeve 22b. The first shoulder clamp 410 is used to grab the left shoulder sleeve 22a, and the second shoulder clamp 420 is used to grab the right shoulder sleeve 22b. The first shoulder clamp 410 and the second shoulder clamp 420 can be relatively close to each other, so that the left shoulder sleeve 22a and the right shoulder sleeve 22b are buckled to the outer side of the upper half of the bottle liner 21 along the opposite sides (left and right sides) of the radial direction of the bottle liner 21 to complete the assembly of the bottle shoulder sleeve 22. It should be noted that the number of bottle shoulder sleeves 22 is not limited, so the number of bottle shoulder clamps is also not limited. It depends on the raw materials produced by the bottle sleeve. For example, in other embodiments, if the number of bottle shoulder sleeves 22 is one, then the number of bottle shoulder clamps is also one, and the bottle shoulder sleeve 22 can be buckled to the upper half of the bottle liner 21 along its axial direction. Therefore, in the present application, any implementation method that can realize the buckling and assembly of the bottle shoulder sleeve 22 on the outer side of the upper part of the bottle liner should be protected.

[0054] Preferably, in combination with reference Figure 5 and Figure 7 In one embodiment, the first shoulder clip 410 is provided with a first profiling suction cup tooling 411, which can be adsorbed on the outer side wall of the left shoulder sleeve 22a so that the first shoulder clip 410 can grab the left shoulder sleeve 22a. The second shoulder clip 420 is provided with a second profiling suction cup tooling 421, which can be adsorbed on the outer side wall of the right shoulder sleeve 22b so that the second shoulder clip 420 can grab the right shoulder sleeve 22b. The first profiling suction cup tooling 411 and the second profiling suction cup tooling 421 can be relatively close to each other, so as to buckle the left shoulder sleeve 22a and the right shoulder sleeve 22b on the outer side of the upper half of the bottle liner 21 along the opposite sides (left and right sides) of the radial direction of the bottle liner 21. The first profiling suction cup tooling 411 and the second profiling suction cup tooling 421 are both provided with a notch whose contour is adapted to the bottle shoulder sleeve 22. Here, the copy suction cup tooling is mainly used for batch high-efficiency processing of easy-to-cut materials such as aluminum plates, copper plates, plastic plates, and wood. It is suitable for high-efficiency processing of parts blanks made of aluminum plates, copper plates, plastic plates, etc. In the field of high-precision processing, it is mainly used for easily deformed parts, and can ensure the shape and position tolerances such as parallelism and flatness of parts.

[0055] Preferably, in combination with reference Figures 8 to 10In one embodiment, the automation device 10 further includes a tightening mechanism 14, which includes a bottle body fastening assembly 510 and a bottle bottom fastening assembly 610. The bottle body fastening assembly 510 is provided at the bottle body conveying unit 500 and is used to further stably assemble the bottle body sleeve 23 on the bottle liner 21. The bottle bottom fastening assembly 610 is provided at the bottle bottom conveying unit 600 and is used to further stabilize the bottle bottom sleeve 24 on the bottle liner 21. Here, the bottle body fastening assembly 510 can be integrated into the robot arm of the bottle body conveying unit 500, or it can be a separate operating unit provided in front of the bottle bottom conveying unit 600; the bottle bottom fastening assembly 610 can be integrated into the robot arm of the bottle bottom conveying unit 600, or it can be a separate operating unit provided in front of the discharging unit 700.

[0056] The bottle body fastening assembly 510 has the same structure as the bottle bottom fastening assembly 610, and both include a stepper motor 511, a rotating shaft 512, a spring 513, a sleeve 514, and a clamp 515. The axial direction of the rotating shaft 512 is parallel to the axial direction of the bottle liner 21, that is, it stands vertically. One end of the rotating shaft 512 is fixed to the stepper motor 511, and the other end of the rotating shaft 512 is provided with a plurality of circumferentially spaced notches 516, and the outer side of the rotating shaft 512 is also provided with an external thread. The number of springs 513 is the same as the number of notches 516, and one end of the spring 513 is fixed to the inner side wall of the notch 516, and the other end of the spring 513 is suspended, and the spring 513 can move in and out of the notch 516 to undergo elastic deformation, and the sleeve 514 is threadedly sleeved on the outer side of the rotating shaft 512. The clamping jaw 515 includes a plurality of clamping blocks 517 having the same number as the notch 516. The plurality of clamping blocks 517 can be brought close to each other and closed to change the size of the clamping space of the clamping jaw 515, thereby clamping the bottle bottom sleeve 24 and releasing the bottle body sleeve. Each clamping block 517 is rotatably installed in the notch 516 in the form of a seesaw. The length extension direction of the clamping block 517 is inclined to the axial direction of the rotating shaft 512. The clamping block 517 has a rotating end 5171 and a grabbing end 5172 opposite to each other. One end of the spring sheet 513 is suspended against the outer side wall of the rotating end 5171, and one end of the sleeve 514 is against the outer side wall of the grabbing end 5172.

[0057] When the stepper motor 511 is started, the stepper motor 511 drives the rotating shaft 512 to rotate circumferentially. Since the rotating shaft 512 is circumferentially threadedly connected to the sleeve 514, the rotation of the rotating shaft 512 can synchronously drive the sleeve 514 to rise and fall. When the sleeve 514 descends, the lower end of the sleeve 514 simultaneously squeezes the outer side walls of the plurality of gripping ends 5172, so that the plurality of gripping ends 5172 are close to each other to clamp the bottle bottom sleeve 24. At the same time, according to the seesaw principle, the plurality of rotating ends 5171 are tilted outwardly along the radial direction of the rotating shaft 512 and away from each other, and the suspended ends of the plurality of spring sheets 513 are pressed outwardly to accumulate elastic force, which can drive the clamping block 517 to reset and release the bottle body sleeve 23 or the bottle bottom sleeve 24.

[0058] Second embodiment

[0059] Combined with reference Figure 2 and Figure 3 , the results of each loading, unloading, pressing, and tightening operation unit used to realize the assembly of the bottle liner 21 with the bottle outer shell in this embodiment are basically the same, except that the positioning device 200 is a single-circle station. Specifically, the positioning device 200 includes a circle of positioning blocks 230, and the bottle liner 21 is inverted and buckled on the positioning blocks 230. The assembly device 1 also includes a pressing mechanism 15 suspended above the rotating disk 100. The pressing mechanism 15 includes a bottle liner pressing unit 800 and a bottle bottom pressing unit 900. The bottle liner pressing unit 800 and the bottle bottom pressing unit 900 are both installed on the operating table 11 through the support rod 101 and suspended above the edge of the rotating disk 100. In the circumferential direction of the turntable 100, the bottle liner pressing unit 800 is located between the bottle liner conveying unit 300 and the bottle shoulder conveying unit 400, and the bottle liner pressing unit 800 is used to further press the bottle liner 21 along its axial direction to be buckled on the positioning block 230. Furthermore, the positioning block 230 is made of elastic material and can be elastically deformed, so that the positioning block 230 and the bottle mouth of the bottle liner 21 are assembled in an interference fit. In the circumferential direction of the turntable 100, the bottle bottom pressing unit 900 is located between the bottle bottom conveying unit 600 and the discharging unit 700, and the bottle bottom pressing unit 900 is used to further press the bottle bottom sleeve 24 to be buckled on the bottom outer side of the bottle liner 21.

[0060] refer to Fig.11 In this embodiment, the bottle liner pressing unit 800 has the same structure as the bottle bottom pressing unit 900. Both pressing units include a lifting motor 810 and a pressing platform 820. The lifting motor 810 is fixed to the side of the corresponding support rod 101 away from the operating platform 11, and the pressing platform 820 is connected to the output end of the lifting motor 810. The lifting motor 810 controls the pressing platform 820 to slide up and down to achieve lifting. The pressing platform 820 can be driven down by the lifting motor 810 to further snap the bottle liner 21 to the positioning block. The pressing platform 820 can be driven down by the lifting motor 810 to further snap the bottle bottom sleeve 24 to the bottle bottom of the bottle liner 21. The specific structure of lifting and pressing can refer to patent CN219092597U. It should be noted that the bottle liner pressing unit 800 is to further improve the buckling stability between the bottle liner 21 and the positioning block 210, and may not be provided in other embodiments; the bottle bottom pressing unit 900 is also to further improve the buckling stability of the bottle bottom sleeve, and may not be provided in other embodiments.

[0061] Preferably, in combination with reference Figure 2 and Fig.11In one embodiment, a positioning hole 231 is provided on the positioning block 230, and the bottle liner 21 is inverted so that its bottle mouth is inserted into the positioning hole 231. Here, the positioning block 230 can be elastically deformed to change the space size of the positioning hole 231, so that the inner wall surface of the positioning hole 231 and the outer wall surface of the bottle mouth of the bottle liner 21 are interference-fitted to improve the buckling stability. It should be noted that in other embodiments, there is no need to set the positioning hole 231, the positioning block 230 is adapted to the bottle mouth of the bottle liner 21, and the outer wall of the positioning block 230 and the inner wall of the bottle mouth are interference-fitted and installed to achieve the function of inverting the bottle liner 21 on the positioning block 230. Therefore, in this application, as long as the bottle liner 21 is inverted and buckled on the positioning block 230, it should be protected. In addition, it should be noted that as long as the fixing method that can install and fix the bottle liner 21 on the operating table 11 for convenient processing and assembly should be protected, such as clamping fixation, limit fixation and other fixing methods.

[0062] Combined with reference Figure 4 and Fig.12 The bottle liner conveying unit 300 includes a material sorter 310, a conveying rail 320 and a robot 330. The discharge port of the material sorter 310 is aligned and connected with the inlet of the conveying rail 320. The robot 330 is suspended on the operating table 11 through the support rod 101 and is located at the exit position of the conveying rail 320. The material sorter 310 here is a circular can sorting plate. The can sorting plate guides the disordered bottle liners 21 from the inner side of the edge of the can sorting plate to the conveying rail 320 in an orderly manner through the principle of rotating centrifugation, and continues to orderly convey the bottle liners 21 from the discharge port of the conveying rail 320 through the conveyor belt on the conveying rail 320. The robot 330 can grab the bottle liners 21, and install the bottle liners 21 on the positioning device 200 by controlling the movement of the robot 330 through a program.

[0063] Specifically, in conjunction with reference Figure 4 and Fig.12 In this embodiment, the robot 330 includes a horizontal axis motor 331, a vertical axis motor 332, a rotary cylinder 333 and a mechanical claw 334. The horizontal axis motor 331 drives and controls the mechanical claw 334 to move horizontally along the length direction of the conveying guide rail 320; the vertical axis motor 332 is used to drive and control the mechanical claw 334 to move up and down, and the rotary cylinder 333 drives and controls the mechanical claw 334 to swing along the axial direction of the bottle liner 21 to achieve a 180° flip of the bottle liner 21 along its axial direction, so as to switch the bottle liner 21 between the upright state and the inverted state.

[0064] It should be noted that the mechanical claw 334 is located directly above the exit of the conveying guide rail 320 and can change the size of its own clamping space to achieve the function of clamping and releasing the bottle liner 21. The interconnection setting of the horizontal axis motor 331, the vertical axis motor 332, and the rotary cylinder 333 is not limited, and the three move in coordination to achieve the three degrees of freedom of the robot 330, namely horizontal movement, vertical lifting movement and rotation and flipping. It should also be noted that in the embodiment where the positioning device 200 is a double-circle station, since the entire assembly process of the bottle liner 21 is in an upright state, the robot 330 does not need to be provided with a rotary cylinder 333 to achieve the flipping of the bottle liner 21. The robot 330 only needs to translate the two degrees of freedom up and down and left and right to achieve the loading process of the bottle liner 21. It should be noted that in the present application, each loading unit and discharging unit has a corresponding material sorter 310, a conveying guide rail 320 and a robot 330, and the structure of each part is basically the same as that of the bottle liner conveying unit 300, which is used to realize the loading and conveying of various parts of the bottle jacket and the output of products. In addition, in the present application, the robot 330 at each position has a slide cylinder in the moving action, and a servo motor is assembled on the slide cylinder. The servo motor can accurately and stably control the moving distance of the robot 330, so that the robot 330 can stably and accurately grasp and release the bottle liner 21, the bottle shoulder sleeve 22, the bottle body sleeve 23, the bottle bottom sleeve 24 and the discharging product 20.

[0065] The number of positioning devices 200 of the automation device 10 of the present application can correspond to one circle of stations or multiple circles of stations. For the positioning device 200 of one circle of stations (positioning block 230), the loading mechanism 12 and the discharging mechanism 13 need to control the time of coordinating the loading and discharging, so that the turntable 100 rotates to the aligned unit to perform the corresponding loading and assembly and product export operations, which requires orderly coordination between the units. For the positioning device 200 of multiple circles of stations, one loading unit or multiple loading units can be controlled to be assembled on the same circle of stations, and the time to complete an assembly process is shorter than that of one circle of stations, which can improve productivity.

[0072] S60, outputting the discharged product 20, the discharge unit 700 starts to work when it is aligned with the positioning device 200, and discharges the discharged product 20 with the assembled bottle jacket from the turntable 100.

[0073] Preferably, in one embodiment, when the positioning device 200 includes an outer ring positioning groove 210 and an inner ring positioning groove 220, the bottle liner 21 is placed in the outer ring positioning groove 210 or the inner ring positioning groove 220 during the entire process of assembling the bottle outer shell, and the bottle liner 21 can be switched between the outer ring positioning groove 210 and the inner ring positioning groove 220 corresponding to any station. The outer ring positioning groove 210 is used for processing, and the inner ring positioning groove 220 is used to transfer the processed product to the next station.
