Description

Technical Field

[0001] This invention relates to a bag transfer device for a high-speed bag feeding and packaging machine. Background Technology

[0002] Currently, rotary bag-feeding packaging machines for bags with openings at the top mainly use rotary bag transfer devices to transfer the bags. These devices rely on the intermittent rotation of a circular turntable to sequentially transfer the bags to various workstations located around the turntable. However, because the edges of the turntable are curved, space utilization is poor, and it is difficult to install many processing devices at each workstation, which makes it difficult to significantly improve work efficiency.

[0003] For example, a large bag-feeding packaging machine disclosed in Chinese patent document CN 223327938 U, entitled "Large Bag-Feeding Packaging Machine," includes an indexing turntable, an adjustable load-bearing tray, a transfer device, and a dual-station vacuum sealing device. The indexing turntable has first bag-clamping assemblies evenly distributed along its edge, with a liftable load-bearing tray below to prevent bag sagging. The transfer device precisely transfers the packaging bags via a first linear motion module and a composite clamping mechanism. The vacuum sealing device employs a dual vacuum chamber and a multi-directional moving cap, integrating bag clamping, bag support, and heat-sealing components within the cap for alternating operation.

[0004] However, the structure of this circular turntable limits the number of processing devices that can be installed at each station; typically, only one processing device is installed at each station. Even if two or more processing devices exist, their drive units are difficult to share. This not only hinders the improvement of the packaging machine's efficiency but also results in a large number of drive units, complex equipment structure, and heavy weight. In this type of turntable bag-feeding packaging machine, each bag clamping, opening, and spreading device is driven by a different drive unit to clamp a bag and complete the actions of opening and spreading the bag opening. Its equipment structure is relatively complex, and the applicable range of packaging bag sizes is small. If it is necessary to significantly change the size of the packaging bag to be processed, especially if the width of the packaging bag changes significantly, it is necessary to disassemble the equipment at each station and adjust them one by one or replace them with other equipment that can be used for packaging bags of that size. Summary of the Invention

[0005] The purpose of this invention is to provide a bag transfer device for a high-speed bag-feeding packaging machine. This device allows for the installation of numerous processing devices at each workstation, simplifying the structure, significantly improving work efficiency, and greatly reducing energy consumption. The technical solution adopted is as follows:

[0006] A packaging bag transfer device for a high-speed bag-feeding packaging machine includes a rotating device and a rotating frame. The rotating device has an upwardly extending rotating shaft, and the rotating frame is mounted on the rotating shaft of the rotating device. The rotating frame is characterized by having multiple contour sides of equal length, forming a regular polygonal contour. Each contour side is equipped with a packaging bag clamping, opening, and flattening mechanism. The packaging bag clamping, opening, and flattening mechanism includes multiple packaging bag clamping, opening, and flattening units that can clamp packaging bags and are sequentially distributed along the contour side. The packaging bag clamping, opening, and flattening mechanism also includes...

[0007] The synchronous horizontal bag opening and flattening device drives all packaging bag clamping, opening and flattening units to complete the bag opening or flattening action simultaneously.

[0008] The synchronous bag opening device drives all the bag clamping, opening and flattening units to complete the clamping and releasing actions simultaneously.

[0009] In a preferred embodiment, the packaging bag clamping, opening, and flattening unit includes a left clamping component and a right clamping component; the synchronous lateral opening and flattening device includes at least one synchronous lateral opening and flattening unit, which includes a screw, two screw positioning seats, a screw drive component, and two nuts. The two screw positioning seats are respectively mounted on a rotating frame, and the screw is rotatably mounted on the two screw positioning seats. The left and right sides of the circumferential surface of the screw are respectively provided with positive and negative threads. The two nuts are respectively sleeved on the screw and threadedly connected to the screw. The two nuts are respectively located on the left and right sides of the screw. The screw drive component is connected to the screw and drives the screw to rotate. The left clamping component of all packaging bag clamping, opening, and flattening units is connected to one nut, and the right clamping component of all packaging bag clamping, opening, and flattening units is connected to the other nut.

[0010] In a more preferred embodiment, the synchronous horizontal bag opening and flattening unit further includes a horizontal track, a first slider group, and a second slider group. The horizontal track is mounted on a rotating frame and is positioned on the corresponding contour edge. The first slider group includes multiple left sliders, and the second slider group includes multiple right sliders. All left sliders of the first slider group and all right sliders of the second slider group are respectively mounted on the horizontal track. The number of left sliders of all synchronous horizontal bag opening and flattening units is the same as the number of left clamping parts of all packaging bag clamping and flattening units, and they correspond one-to-one. Each left clamping part is mounted on its corresponding left slider. The number of right sliders of all synchronous horizontal bag opening and flattening units is the same as the number of right clamping parts of all packaging bag clamping and flattening units, and they correspond one-to-one. Each right clamping part is mounted on its corresponding right slider.

[0011] In a more optimized embodiment, the synchronous lateral bag opening and flattening unit further includes a first sliding plate and a second sliding plate. The left clamping parts of all packaging bag clamping, opening, and flattening units are connected to the first sliding plate, and the right clamping parts of all packaging bag clamping, opening, and flattening units are connected to the second sliding plate. The first and second sliding plates are each connected to two nuts, which respectively drive the first and second sliding plates to slide on the top surface of the rotating frame. In this way, when the screw drive is activated, it can drive all packaging bag clamping, opening, and flattening units to open or close.

[0012] In one embodiment, the screw drive is a first servo motor, which is mounted on a rotating frame. The first output shaft of the first servo motor is connected to the screw and drives the screw to rotate.

[0013] In another embodiment, the screw drive includes a second servo motor, a synchronous belt, and two synchronous pulleys. The second servo motor is mounted on a rotating frame, and the two synchronous pulleys are respectively mounted on the second output shaft of the second servo motor and one end of the screw. The synchronous belt is sleeved on the two synchronous pulleys.

[0014] In a preferred embodiment, the left clamping member is in a normally closed clamping state and has a left release control end for opening the left clamping member; the right clamping member is in a normally closed clamping state and has a right release control end for opening the right clamping member; the synchronous bag opening device includes at least one bag opening drive unit, which includes a telescopic member and an operating plate. The telescopic member is mounted on the rotating frame and has a telescopic action end. All telescopic action ends are connected to the operating plate and drive the operating plate to perform telescopic movement; when all operating plates extend, the left release control ends of all left clamping members are pushed to open the left clamping members, and the right release control ends of all right clamping members are pushed to open the right clamping members; when all operating plates retract, all left clamping members and all right clamping members return to the normally closed clamping state.

[0015] A better solution is that the telescopic component is a cylinder, and the telescopic action end of the telescopic component is the piston shaft of the cylinder.

[0016] A preferred approach is to have 3-6 sides in the regular polygon.

[0017] A better solution is to have 3 edges and 3 processing stations.

[0018] A better solution is to have 4 edges and 4 processing stations.

[0019] In a preferred embodiment, the rotating frame is provided with multiple processing stations around its perimeter. The number of processing stations is the same as the number of sides of the regular polygon and they correspond one-to-one. Each processing station is provided with the same number of processing devices. The number of packaging bag clamping, opening and flattening units is the same as the number of processing devices and they correspond one-to-one.

[0020] A better solution is to have the same number of bag-clamping, opening, and flattening units in the bag-clamping, opening, and flattening mechanism as the number of processing devices at each workstation, which is 3-20. Too few units would make this rotating frame structure unnecessary; while too many units would result in an excessively large machine space, rendering it impractical.

[0021] The advantages of this invention compared to the prior art are that, by using a regular polygonal contour instead of the traditional circular contour, the number of processing devices that can be installed at each workstation is greatly increased. Moreover, each workstation can employ a bag clamping, opening, and flattening mechanism, and a single drive device can drive all bag clamping, opening, and flattening units at that workstation to complete the opening and flattening actions. Furthermore, it is applicable to a wide range of bag widths, and a single drive device can simultaneously operate all bag clamping, opening, and flattening units to complete the clamping and releasing actions. The regular polygonal contour and the bag clamping, opening, and flattening mechanism work together to greatly optimize the structure of the high-speed bag packaging machine, reduce equipment costs, significantly improve work efficiency, greatly expand the applicability of the equipment, and effectively reduce noise.

[0033] The synchronous bag opening device 303 drives all the packaging bag clamping, opening and flattening units 301 to simultaneously complete the clamping and releasing actions.

[0034] like Figure 5-8As shown, in an optional embodiment of this application, the packaging bag clamping, opening, and flattening unit 301 includes a left clamping member 3011 and a right clamping member 3012; the synchronous transverse opening and flattening device 302 includes at least one synchronous transverse opening and flattening unit 3021, which includes a screw 30211, two screw positioning seats 30212, a screw drive member 30213, two nuts 30214, a transverse track 30215, a first slider group 30216, a second slider group 30217, a first slidable plate 30218, and a second slidable plate 30219. The two screw positioning seats 30212 are respectively mounted on the rotating frame 2, and the screw 30211 can... The screw 30211 is rotatably mounted on two screw positioning seats 30212. The left and right sides of the circumferential surface of the screw 30211 are respectively provided with positive and negative threads. Two nuts 30214 are respectively sleeved on the screw 30211 and threadedly connected to it. The two nuts 30214 are located on the left and right sides of the screw 30211. A screw drive 30213 is connected to the screw 30211 and drives it to rotate. A transverse track 30215 is mounted on the rotating frame 2 and is set on the corresponding contour edge. The first slider group 30216 includes multiple left sliders 302161, and the second slider group 30217 includes multiple right sliders 302171. All left sliders 302161 of the first slider group 30216 and all right sliders 302171 of the second slider group 30217 are respectively mounted on the transverse track 30215. The number of left sliders 302161 of all synchronous transverse bag opening and flattening units 3021 and the number of left clamping parts 3011 of all packaging bag clamping, opening, and flattening units 3011 are the same and correspond one-to-one. Each left clamping part 3011 is installed on its corresponding left slider 302161. The number of right sliders 302171 of all synchronous transverse bag opening and flattening units 3021 and the number of right clamping parts 3012 of all packaging bag clamping, opening, and flattening units 3011 are the same and correspond one-to-one. Each right clamping part 3012... Each of the left clamping parts 3011 and the right clamping parts 3012 is installed on the corresponding right slider 302171. The rear ends of all left clamping parts 3011 are fixed on the first sliding plate 304, and the rear ends of all right clamping parts 3012 are fixed on the second sliding plate 305.

The two nuts 30214 drive the first sliding plate 304 and the second sliding plate 305 to slide on the top surface of the rotating frame 2.

[0035] like Figure 5-8 As shown, in one alternative embodiment of this application, the number of the synchronous lateral bag opening and flattening unit 3021 is one.

[0036] In one alternative embodiment of this application, the number of synchronous lateral bag opening and flattening units 3021 is two.

[0037] In one alternative embodiment of this application, the number of synchronous lateral bag opening and flattening units 3021 is three.

[0038] In one alternative embodiment of this application, the screw drive 30213 is a first servo motor, which is mounted on the rotating frame 2. The first output shaft of the first servo motor is connected to the screw 30211 and drives the screw 30211 to rotate.

[0039] like Figure 5-8 As shown, in an optional embodiment of this application, the screw drive 30213 includes a second servo motor 302131, a synchronous belt 302132, and two synchronous pulleys 302133. The second servo motor 302131 is mounted on the rotating frame 2, and the two synchronous pulleys 302133 are respectively mounted on the second output shaft of the second servo motor 302131 and one end of the screw 30211. The synchronous belt 302132 is sleeved on the two synchronous pulleys 302133.

[0040] like Figure 8 , 9 As shown, in an optional embodiment of this application, the left clamping member 3011 is in a normally closed clamping state and has a left release control end 30111 for opening the left clamping member 3011; the right clamping member 3012 is in a normally closed clamping state and has a right release control end 30121 for opening the right clamping member 3012; the synchronous bag opening device 303 includes at least one bag opening drive unit 3031, the bag opening drive unit 3031 includes a telescopic member 30311 and an operation plate 30312, the telescopic member 30311 is mounted on the rotating frame 2. The telescopic component 30311 has a telescopic action end 303111, which is connected to the operating plate 30312 and drives the operating plate 30312 to perform telescopic movement. When all operating plates 30312 extend, they simultaneously push the left release control end 30111 of all left clamping components 3011 to open the left clamping component 3011 and push the right release control end 30121 of all right clamping components 3012 to open the right clamping component 3012. When all operating plates 30312 retract, all left clamping components 3011 and all right clamping components 3012 return to the normally closed clamping state.

[0041] like Figure 8 , 9 As shown, in one alternative embodiment of this application, the number of the bag opening drive units 3031 is two.

[0042] In one alternative embodiment of this application, the number of the bag opening drive unit 3031 is one.

[0043] In one alternative embodiment of this application, the number of bag-opening drive units 3031 is three.

[0044] like Figure 5-9 As shown, in one alternative embodiment of this application, the telescopic member 30311 is a cylinder, and the telescopic action end 303111 of the telescopic member 30311 is the piston shaft of the cylinder.

[0045] like Figure 5-9 As shown, in one alternative embodiment of this application, the operation panel 30312 is slidably mounted on the rotating frame 2 (using a slide rail and slider connection method).

[0046] The regular polygon has 3-6 sides.

[0047] like Figure 1 As shown, in one optional embodiment of this application, the number of sides is 4 and the number of processing stations is 4.

[0048] In one optional embodiment of this application, the number of sides is 3 and the number of processing stations is 3.

[0049] In one optional embodiment of this application, the number of sides is 6 and the number of processing stations is 6.

[0050] A high-speed bag-feeding packaging machine manufactured using an optional embodiment of this application has four processing stations, which are respectively a bag-feeding station, a bag-opening station, a material-unloading station, and a sealing station. All processing equipment at the bag-feeding station is a bag-feeding device; all processing equipment at the bag-opening station is a bag-opening device; all processing equipment at the material-unloading station is a filling device; and all processing equipment at the sealing station is a sealing device. In this embodiment, the bag-feeding device uses a robotic arm to transport the packaging bag to the bag-clamping, opening, and flattening mechanism 3. The bag-opening device uses two suction cups to pull the two side walls of the packaging bag outwards, opening the bag. The filling device fills the packaging bag with material. The sealing device seals the bag opening. Since these processing devices employ common techniques in the art, they will not be described in detail here.

[0051] It is important to emphasize that the left clamping member 3011 and right clamping member 3012 of each packaging bag clamping and flattening unit 301 grip the two sides of the corresponding packaging bag opening at the bag opening station, moving in opposite directions to assist in opening the bag opening or to open the bag opening independently. For some packaging bags with a large width, a bag opening device consisting of two vacuum suction cups is used to suction the two outer sides of the packaging bag, and the packaging bag clamping and flattening unit 301 works in conjunction with it to open the bag opening. At the sealing station or unloading station, before the sealing device starts sealing or after the filling device starts filling, the packaging bag clamping and flattening unit 301 needs to grip the two sides of the corresponding packaging bag opening and move in opposite directions to flatten the bag opening. It is worth emphasizing that by adjusting the stroke of the left clamping member 3011 and right clamping member 3012 of the packaging bag clamping and flattening unit 301, it can be adapted to packaging bags of different widths, thus having a very wide range of applications. Moreover, when the width of the packaging bag changes too much, the number of packaging bag clamping, opening and flattening units 301 can be increased or decreased to make the packaging bag clamping, opening and flattening units 301 adapt to the packaging bag, which is very convenient and quick.

[0052] In one optional embodiment of this application, the number of sides is 3 and the number of processing stations is 3.

[0053] The number of packaging bag clamping, opening, and flattening units 301 in the packaging bag clamping, opening, and flattening mechanism 3 ranges from 3 to 20, corresponding to the number of processing devices at each workstation. Too few units would make it unnecessary to use this type of rotating frame 2; while too many units would result in excessive space usage and render the machine impractical.

[0054] like Figure 1-9 As shown, in one optional embodiment of this application, the number of packaging bag clamping, opening and flattening units 301 of the packaging bag clamping, opening and flattening mechanism 3 and the number of processing equipment at each workstation are both 10.

[0055] In one optional embodiment of this application, the number of packaging bag clamping, opening, and flattening units 301 of the packaging bag clamping, opening, and flattening mechanism 3 is 5, and the number of processing devices at each workstation is also 5.

[0056] In one optional embodiment of this application, the number of packaging bag clamping, opening, and flattening units 301 of the packaging bag clamping, opening, and flattening mechanism 3 is 8, and the number of processing devices at each workstation is also 8.

[0057] In one optional embodiment of this application, the number of packaging bag clamping, opening, and flattening units 301 of the packaging bag clamping, opening, and flattening mechanism 3 and the number of processing devices at each workstation are both 20.

[0058] In one alternative embodiment of this application, the number of packaging bag clamping, opening, and flattening units 301 of the packaging bag clamping, opening, and flattening mechanism 3 and the number of processing devices at each workstation are both 15.

[0059] In one optional embodiment of this application, the number of packaging bag clamping, opening, and flattening units 301 of the packaging bag clamping, opening, and flattening mechanism 3 is three, as is the number of processing devices at each workstation.

[0060] like Figure 1 As shown, in an alternative embodiment of this application, the high-speed bag-feeding packaging machine further includes a base 4, and a rotating device 1 is mounted on the base 4.

[0061] like Figure 1 , 3 As shown, in one optional embodiment of this application, the rotating device 1 consists of a servo motor and a cam divider. The servo motor outputs power to drive the cam divider, which in turn drives the rotating frame 2 to rotate intermittently. Since the technical solution of this rotating device 1 is a common technique in the field, it will not be described in detail.

[0062] Because the rotating frame 2 is designed as a regular polygon, the number of processing devices that can be placed at each station can be significantly increased compared to the traditional circular contour. Without significantly increasing space and raw material usage, work efficiency is greatly improved, thus meeting the needs of producers. Furthermore, this contour allows each station to employ a bag clamping, opening, and flattening mechanism. A single drive unit can drive all bag clamping, opening, and flattening units at that station to complete the opening and flattening actions. It is also suitable for a wide range of bag widths. A single drive unit can simultaneously operate all bag clamping, opening, and flattening units to complete the clamping and releasing actions. The regular polygonal contour and the bag clamping, opening, and flattening mechanism work together to greatly optimize the structure of the high-speed bag-feeding packaging machine, reduce equipment costs, significantly improve work efficiency, greatly expand the applicability of the equipment, and effectively reduce noise.

[0063] Furthermore, it should be noted that the names of the various parts of the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structure, features, and principles described in this invention are included within the scope of protection of this invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this invention or exceed the scope defined in these claims, all of which should fall within the scope of protection of this invention.
