Description

Technical Field

[0001] This utility model relates to a bag-in-a-box filling device, specifically a bag-in-a-box automatic filling, heat transfer printing and labeling integrated machine. Background Technology

[0002] In the fields of daily chemical or food packaging, the use of packaging machinery to automate product packaging, replacing traditional manual operations, can greatly reduce repetitive manual labor, reduce the labor intensity of workers, and improve packaging efficiency.

[0003] The complete packaging process for daily chemicals or food typically includes filling, capping, printing labels and affixing labels. In the existing technology, the above processes are all divided into separate tasks by independently set filling equipment, capping equipment, heat transfer printing equipment and labeling equipment, and the products are moved between different equipment by operators.

[0004] Chinese utility model patent CN213832325U discloses a filling equipment and system for flexible bag packaging. The filling equipment includes a ton bag box, a frame, and a lifting support mounted on the upper part of the frame. The lifting support is mounted on the output end of a first drive unit, which drives the lifting support to move linearly. A translation support is mounted on the lifting support, which is mounted on the output end of a second drive unit. A capping mechanism and a filling valve mechanism are mounted side-by-side on the translation support. Its key feature is the simultaneous configuration of a capping mechanism and a filling valve mechanism, enabling the completion of both capping and filling processes on the same machine.

[0005] However, for the overall packaging process, a separate labeling and marking process is still required. This involves separate heat transfer printing and labeling equipment, which then print and label the bags separately before installing them onto the designated filling station of the filling equipment for filling. This method requires manual transport of the bags between the heat transfer printing, labeling, and filling equipment, each requiring dedicated installation space. This setup not only increases labor costs but also reduces factory space utilization. Utility Model Content

[0006] The purpose of this utility model is to solve the technical problems in the prior art where filling equipment, labeling equipment and heat transfer printing equipment are set up separately, resulting in increased labor costs and low utilization of factory space. The present invention provides an integrated machine for automatic bag-in-box filling, heat transfer printing and labeling.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A box-in-bag automatic filling, heat transfer printing and labeling integrated machine is characterized by: including a frame, a box-in-bag conveying device, a heat transfer printing device and a filling device set in the frame;

[0009] The thermal transfer printing equipment includes a thermal transfer printer, which is mounted on the frame via a support frame.

[0013] The first pressure roller has multiple conveying rollers connected to the labeling equipment support frame on the side away from the labeling platform. The height of the axis of the multiple conveying rollers increases sequentially along the bag-in-box conveying direction. The second pressure roller has a support roller connected to the labeling equipment support frame on the side away from the labeling platform.

[0014] Based on the same horizontal plane, we define: the highest height of the multiple conveying rollers is h1, the lowest height of the first pressure roller is h2, the lowest height of the second pressure roller is h3, and the highest height of the support roller is h4. Then we have: h1>h2, h4>h3.

The upper end of the labeling equipment mounting block is fixedly connected to the labeling machine.

[0019] Furthermore, the support frame includes a horizontal bar, with adjusting plates connected to both ends of the horizontal bar. Each adjusting plate has a first limiting elongated hole. Adjusting bolts located at both ends of the support frame pass through the first limiting elongated holes and are connected to the first and second support rods of the frame.

Alternatively, the photoelectric detection switch includes a transmitter and a receiver, with the transmitter mounted on the first support rod and the receiver mounted on the frame below the transmitter. The photoelectric detection switch is used to detect the passage of each bag in a box on the bag-in-box conveying device.

[0021] Furthermore, the bag-in-box conveying device includes a drive unit electrically connected to the external control device, a drive unit mounting bracket, and two parallel slide rails;

[0022] The slide rail is fixedly connected to the frame, and the bottom of the slide rail is fitted with the operating platform of the frame to form a conveying channel for the bag in the box, and a cover slide is formed between the two slide rails;

[0023] One end of the drive device mounting frame is connected to the second support rod, and the other end is connected to the third support rod of the frame. The drive device is mounted on the drive device mounting frame. The drive end of the drive device reciprocates along the conveying direction of the bag in the box. The drive end is rotatably connected to a drive rod. The end of the drive rod has a jaw for pushing the bag in the box cover. A rear rotation limiting structure is provided between the drive rod and the drive end so that the drive rod can push the bag in the box to the filling station of the filling equipment, and can also lift it up when returning and pass over the next cover.

[0024] Furthermore, the rear rotation limiting structure includes a pair of mounting ears disposed at the drive end, a pin connecting the two mounting ears, and a limiting platform disposed on the lower side of the drive end; the upper end of the drive rod is rotatably connected to the pin, so that the drive rod can rotate relative to the drive end, and the rear side of the drive rod can selectively abut against the limiting platform.

[0025] Furthermore, the drive rod is in the shape of a broken line, including a vertical section, a bent section and a horizontal section connected in sequence from top to bottom. One end of the vertical section is rotatably connected to the pin shaft, the front end of the horizontal section is connected to the jaws, the jaws are semi-circular jaws, and the rear side of the vertical section is used to selectively abut against the limiting platform.

[0026] Furthermore, the bag-in-box conveying device also includes a bag-in-box conveying frame, which includes a support plate and two support guide rails;

[0027] A support plate is disposed on the rear side of the reflector or receiver and is connected to the frame. The support plate protrudes from the operating platform of the frame.

[0029] Furthermore, two positioning rings are slidably disposed on one of the multiple conveying rollers to allow the bag in the box to be transported within the range defined by the two positioning rings.

[0030] Compared with existing technologies, the automatic bag-in-box filling, heat transfer printing and labeling integrated machine provided by this utility model has the following advantages:

[0031] 1. This utility model is an integrated automatic bag-in-box filling, heat transfer printing and labeling machine. It consists of a labeling device, a heat transfer printing device, a bag-in-box conveying device and a filling device connected in sequence on the frame by mechanical transmission. The bag-in-box conveying device transports the bag-in-box labeled and printed by the labeling device and the heat transfer printing device to the filling device for filling, thus saving equipment installation space.

[0032] 2. This utility model is an integrated automatic bag-in-box filling, heat transfer printing and labeling machine. By setting up a labeling equipment support frame, it adds a labeling machine installation position to the original filling equipment, saving factory equipment installation space. Furthermore, with the installation frame, when the labeling position changes, only the position of the installation frame needs to be adjusted to adjust the labeling position.

[0033] 3. This utility model is an integrated machine for automatic filling, heat transfer printing and labeling of bag-in-box. The bag-in-box is supported to a certain height by conveying rollers and support rollers. The first pressure roller and the second pressure roller press the bag-in-box, which is supported to a certain height, downwards, so that the bag-in-box above the labeling platform has a certain tension, thereby keeping the bag-in-box flat and facilitating labeling.

[0034] 4. This utility model is an integrated machine for automatic filling, heat transfer printing, and labeling of bag-in-box. By setting up a support frame, when the size of the bag-in-box and the printing position are adjusted, the left and right positions of the heat transfer printer can be adjusted by loosening the adjusting bolts, and the position of the adjusting screw in the second limit hole can be adjusted by loosening the adjusting screw. This allows for positioning in four directions, making the printing position adjustment more flexible and adaptable to the printing needs of more sizes of bag-in-box.

[0035] 5. This utility model is an integrated machine for automatic filling, heat transfer printing and labeling of bags in a box. The slide rail and the operating platform are fitted with a gap to allow the bag in the box to pass smoothly through the gap. The cover protrudes from the slide rail, which facilitates the drive rod to push the cover forward.

[0036] 6. This utility model is an integrated automatic bag-in-box filling, heat transfer printing, and labeling machine. Through a pin-shaft rotation connection, the drive rod hangs downwards under gravity, abutting against the end face of the drive end, limiting its continued backward rotation. As the drive end continues to move backward, the cover abuts against the jaws of the drive rod, pushing the drive rod forward and upward. When the jaws pass the cover, they lock the cover in place. This design is convenient and quick.

[0037] 7. This utility model is an integrated machine for automatic filling, heat transfer printing and labeling of bags in boxes. By setting up a conveyor frame, the bags in boxes are raised to a certain height, reducing the contact area between them and the operating platform. This effectively reduces the friction between the bags in boxes and the operating platform, making the automatic transportation of bags in boxes faster and more convenient.

[0038] 8. This utility model is an integrated machine for automatic filling, heat transfer printing and labeling of bag-in-box. It uses a slide rail and two positioning rings to position the bag-in-box at multiple points during transportation, preventing the bag-in-box from deviating from the transport route during the transport process.

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0051] like Figure 1-9 As shown, in order to reduce labor costs and save factory equipment installation space, this utility model designs an integrated automatic bag-in-box filling, heat transfer printing and labeling machine, including a frame 5, a bag-in-box conveying device 3, a heat transfer printing device 2 and a filling device 4 installed in the frame 5; the heat transfer printing device 2 is located at the bag-in-box inlet position near the bag-in-box conveying device 3 and on one side of the bag-in-box conveying device 3; the filling device 4 is located at the outlet position of the bag-in-box conveying device 3; a labeling device 1 is installed on the upper side of the frame 5 near the bag-in-box inlet position of the bag-in-box conveying device (3), the labeling device 1 includes a labeling device support frame 103 connected to the frame 5, a labeling machine 101 is installed on the upper part of the labeling device support frame 103, and a labeling platform 102 is set on the lower part of the labeling machine 101 and the labeling platform 102 are correspondingly set. By setting the labeling device support frame 103, the installation position of the labeling machine 101 is added on the basis of the original filling device 4, saving factory equipment installation space. This application considers the direction of bag-in-box conveying as the front and the opposite direction as the back.

[0052] The thermal transfer printing equipment 2 includes a thermal transfer printer 203, which is mounted on the frame 5 via a support bracket and is used to print labels on the bag-in-box. The filling equipment 4 is used to fill the bag-in-box. The labeling equipment 1, thermal transfer printing equipment 2, bag-in-box conveying device 3, and filling equipment 4 are mechanically connected sequentially on the frame 5. The bag-in-box conveying device 3 transports the labeled and printed bags from the labeling equipment 1 and thermal transfer printing equipment 2 to the filling equipment 4 for filling, saving equipment installation space.

[0053] The labeling machine 101 is detachably connected to the labeling equipment support frame 103 via a mounting frame 113. U-shaped grooves 109 are provided on the lower sides of both ends of the mounting frame 113. The U-shaped grooves 109 are slidably connected to the labeling equipment support frame 103 and their positions are limited by positioning bolts, allowing the mounting frame 113 to move back and forth and be positioned along the bag-in-box conveying direction. When it is necessary to adjust the labeling position of the labeling machine 101, loosen the positioning bolts, adjust the installation position of the mounting frame 113, and after adjustment, tighten the positioning bolts to restrict the movement of the mounting frame 113. By setting up the mounting frame 113, when the labeling position changes, the position of the mounting frame needs to be adjusted to adjust the labeling position.

[0054] A labeling equipment mounting block 110 is slidably connected to the mounting frame 113. One end of the labeling equipment mounting block 110 is U-shaped and slidably connected to the mounting frame 113. The U-shaped end of the labeling equipment mounting block 110 has a through hole, and a limiting bolt is provided in the through hole. The limiting bolt is used to restrict the movement of the labeling equipment mounting block 110. The other end of the labeling equipment mounting block 110 is fixedly connected to the labeling machine 101.

[0055] The labeling equipment support frame 103 is provided with a first connecting rod 105 and a second connecting rod 106 at intervals along the bag-in-box conveying direction. Both ends of the first connecting rod 105 and the second connecting rod 106 are provided with connecting plates that are connected to the frame body 5. Each connecting plate has an adjustment elongated hole 108 arranged in the vertical direction. A limit bolt is provided in the adjustment elongated hole 108. The limit bolt passes through the adjustment elongated hole 108 and is connected to the frame body 5.

[0056] A first connecting rod 105 connects to a first pressure roller 104, and a second connecting rod 106 connects to a second pressure roller 107. Both the first pressure roller 104 and the second pressure roller 107 are clearance-fitted with the labeling platform 102, forming a conveying channel for the bag-in-a-box. The first pressure roller 104 and the second pressure roller 107 are located above the labeling platform 102, either directly above or diagonally above. Multiple conveying rollers 111 connected to the labeling equipment support frame 103 are provided on one side of the first pressure roller 104. The centerline height of the multiple conveying rollers 111 increases sequentially, with the conveying roller closest to the first pressure roller 104 having the highest centerline height. A support roller 112 connected to the labeling equipment support frame 103 is provided on one side of the second pressure roller 107. Based on the same horizontal plane, the highest height of the multiple conveyor rollers 111 is h1, the lowest height of the first pressure roller 104 is h2, the lowest height of the second pressure roller 107 is h3, and the highest height of the support roller 112 is h4, where h1>h2, h4>h3, and h2=h3. The conveyor rollers 111 and the support roller 112 support the bag-in-the-box to a certain height, and the first pressure roller 104 and the second pressure roller 107 press the bag-in-the-box, which is supported to a certain height, downward, so that the bag-in-the-box above the labeling platform 102 has a certain tension, thereby keeping the bag-in-the-box flat and facilitating labeling.

[0057] The thermal transfer printer 203, the bag-in-box conveyor 3, the filling equipment 4, and the labeling machine 101 are all electrically connected to an external control device.

[0058] The support frame includes a horizontal rod 201, with adjusting plates 202 connected to both ends of the horizontal rod 201. The adjusting plates 202 have first limiting holes, through which adjusting bolts at both ends of the support frame pass and connect to the first and second support rods 501 and 502 of the frame body 5. The horizontal rod 201 has a second limiting hole, within which an adjusting screw is installed. The adjusting screw is positioned on the horizontal rod 201 by two positioning nuts. The lower end of the adjusting screw is connected to a thermal transfer printer 203, with a corresponding printing work platform 204 located at the lower part of the thermal transfer printer 203. By setting up the support frame, when the size of the bag-in-the-box and the printing position are adjusted, the adjusting bolts are loosened, and the left and right positions of the thermal transfer printer are adjusted. The adjusting screw is then loosened, and its position in the second limiting hole is adjusted, thereby adjusting the front and rear positions of the thermal transfer printer 203. Positioning in four directions makes the printing position adjustment more flexible and adaptable to printing needs for more sizes of bag-in-the-box.

[0059] The thermal transfer printing equipment 2 also includes a photoelectric detection switch 205, which includes a photoelectric detection sensor and a reflector. The photoelectric detection sensor is mounted on the first support rod 501, and the reflector is mounted on the frame 5 below the photoelectric detection sensor; or the photoelectric detection switch 205 includes a transmitter and a receiver. The transmitter is mounted on the first support rod 501, and the receiver is mounted on the frame 5 below the transmitter. The photoelectric detection switch 205 is used to detect the passage of each bag in a box on the bag-in-box conveying device 3.

[0060] The bag-in-box conveying device 3 includes a drive unit 303 electrically connected to an external control device, a drive unit mounting frame 301, and two parallel slide rails 302. The slide rails 302 are fixedly connected to the frame 5, and the bottom of the slide rails 302 is fitted with the operating platform of the frame 5 with a clearance to form a conveying channel for the bag-in-box. A cover slide is formed between the two slide rails 302. The clearance fit between the slide rails 302 and the operating platform allows the bag-in-box to pass smoothly through the gap, and the cover protrudes from the slide rails 302, facilitating the drive rod to push the cover forward.

[0061] One end of the drive device mounting frame 301 is connected to the second support rod 502, and the other end is connected to the third support rod 503 of the frame 5. The drive device 303 is mounted on the drive device mounting frame 301. The drive end of the drive device 303 reciprocates along the conveying direction of the bag in the box. The drive end is rotatably connected to the drive rod 304. The end of the drive rod 304 has a jaw for pushing the bag in the box cover. A rear rotation limiting structure is provided between the drive rod 304 and the drive end so that the drive rod 304 can push the bag in the box to the filling station of the filling equipment 2, and can also lift it up when returning and pass over the next cover.

[0062] The rear rotation limiting structure includes a pair of mounting ears on the drive end, a pin connecting the two mounting ears, and a limiting platform located on the lower side of the drive end. The upper end of the drive rod 304 is rotatably connected to the pin, allowing the drive rod 304 to rotate relative to the drive end, and the rear side of the drive rod 304 can selectively abut against the limiting platform. Through the pin rotation connection, the drive rod hangs downward under gravity, abutting against the end face of the drive end, limiting its continued rearward rotation. As the drive end continues to move backward, the cover abuts against the jaws of the drive rod, pushing the drive rod forward and upward. When the jaws pass the cover, they lock the cover in place. This configuration is convenient and quick.

[0063] The drive rod 304 is in the shape of a broken line, including a vertical section, a bent section and a horizontal section connected from top to bottom. One end of the vertical section is rotatably connected to a pin shaft, the front end of the horizontal section is connected to a jaw, the jaw is a semi-circular jaw, and the rear side of the vertical section is used for selective abutment with the limiting platform.

[0064] The bag-in-box conveying device 3 also includes a bag-in-box conveying frame, which includes a support plate 305 and two support guide rails 306. The support plate 305 is located on the rear side of the reflector or receiving end and is connected to the frame 5. The support plate 305 protrudes from the operating platform of the frame 5. By setting the conveying frame, the bag-in-box is raised to a certain height, reducing the contact area between it and the operating platform. This effectively reduces the friction between the bag-in-box and the operating platform, making the automatic transport of the bag-in-box faster and more convenient.

[0065] The support rail 306 is located on the operating platform of the frame 5. One end of the support rail 306 is connected to the support plate 305, and the other end is connected to two slide rails 302 respectively.

[0066] Two positioning rings are slidably mounted on one of the multiple conveyor rollers 111 to ensure that the bag-in-box is transported within the range defined by the two positioning rings. The bag-in-box is positioned at multiple points during transport via a slide rail and the two positioning rings, preventing it from deviating from the transport path during delivery.

[0067] The workflow is as follows:

[0068] During the initial bag loading operation, the continuous bags-in-one are manually fed to the filling position of the filling port of the filling equipment 4. After the bags are placed, the automatic operation program of the filling equipment 4 is started, and the equipment automatically begins the filling action. After the first bag-in-one is filled, it is automatically dropped and cut, and at the same time, the second bag is automatically sent to the filling station. After being sent to the filling station, the conveying mechanism (i.e., the drive device 303) returns and conveys the next bag-in-one to the waiting position near the filling port. By using the different stroke control of the drive end of the drive device 303, one drive device 303 can both transport bags-in-one to the filling station and transport bags-in-one to the waiting position. The distance between the filling station and the waiting position is less than the length of one bag-in-one, which can save conveying time and improve efficiency. At this time, the continuous bags in the box are in a static waiting state. The photoelectric detection switch 205 feeds back this information to the external control device. At the same time, the labeling machine 101 communicates with the external control device. That is, the external control device feeds back the information that labeling can be done to the labeling machine 101. The labeling machine 101 starts to execute the labeling command, completes the labeling, and feeds back the labeling completion information to the external control device. When the labeling machine 101 has a labeling failure, it will also feed back information to the external control device. The filling equipment 4 pauses filling and waits for the labeling equipment failure to be processed before it can resume labeling and filling. The thermal transfer printer 203 works simultaneously with the labeling machine 101 to realize the automatic operation of filling, labeling, and thermal transfer printing. During the process, the labeling time is very short, and the filling cycle of the smallest package is longer than the labeling time. Therefore, there is no situation where filling waits for printing, which would affect filling capacity. This effectively integrates the labeling station into the filling equipment, enabling simultaneous operation of filling, labeling, and heat transfer printing. This saves the space disadvantage of having two separate stations and facilitates the matching of filling, heat transfer printing, and labeling operations. The labeling section can adjust the labeling position using the U-shaped slide 109 of the mounting bracket 113 and the limiting bolts to match the labeling requirements of different packaging sizes.

[0069] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
