Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a packaging bag feeding device and a packaging equipment having the same. Background Technology

[0002] The automatic aluminum bag sealing machine industry has shown steady growth in the Chinese market in recent years, becoming an indispensable piece of equipment for industries such as food, pharmaceuticals, and daily chemicals. In the pharmaceutical industry, with the strict implementation of Good Manufacturing Practice (GMP) and the improvement of pharmaceutical standards, the demand for automatic aluminum bag sealing machines has shown a steady upward trend.

[0003] To improve the efficiency of aluminum bag loading, existing technologies utilize automated aluminum bag loading devices. These devices employ a three-axis linear module to drive suction cups along a horizontal guide rail, transporting aluminum bags from the storage position to the loading position. Then, an automatic aluminum bag sealing function can perform subsequent operations such as opening and sealing the aluminum bags at the loading position.

[0004] However, aluminum bag loading devices occupy a large space, making them unsuitable for small-sized applications. Furthermore, because the suction cups require precise alignment with the guide rails, the structure of the aluminum bag loading device is relatively complex, resulting in high manufacturing costs and poor market competitiveness. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a packaging bag feeding device is provided. The packaging bag feeding device includes: a mounting frame with a rotating shaft mounted on it; a storage mechanism for holding packaging bags; and a telescopic mechanism mounted on the rotating shaft, with a suction mechanism connected to its driving end. The rotating shaft drives the telescopic mechanism to rotate around a predetermined axis between a picking position and a discharging position. When the telescopic mechanism is in the picking position, it drives the suction mechanism to pick up the bottom packaging bag from the storage mechanism. When the telescopic mechanism is in the discharging position, the suction mechanism releases the bottom packaging bag, causing it to move to the feeding position.

[0006] For example, the suction mechanism includes a connector and at least one set of suction cup assemblies connected to the connector, the drive end of the telescopic assembly is connected to the connector, and each of the at least one set of suction cup assemblies is used to suction the bottom packaging bag from the storage mechanism and release the bottom packaging bag.

[0007] For example, at least one set of suction cup assemblies includes multiple sets arranged along a predetermined axis, the multiple sets of suction cup assemblies being used to pick up the bottom packaging bag from the storage mechanism in a one-to-one correspondence, and to release the bottom packaging bag.

[0008] For example, each suction cup assembly includes a rectangular plate and suction cups disposed at the four corners of the rectangular plate, with connectors connected to the rectangular plate. The suction cups are used to pick up the bottom packaging bag from the storage mechanism and to release the bottom packaging bag.

[0009] For example, the telescopic mechanism includes a plurality of telescopic mechanisms arranged along a predetermined axis, and the drive ends of the plurality of telescopic mechanisms are connected to suction mechanisms in a one-to-one correspondence; and / or the storage mechanism includes a plurality of telescopic mechanisms arranged along a predetermined axis.

[0010] For example, the mounting frame includes a mounting body and a support assembly. The rotating shaft, the storage mechanism and the support assembly are all disposed on the mounting body. The support assembly and the storage mechanism are located on both sides of the mounting body. The mounting body and the support assembly together form an accommodating space. At least a portion of the rotating shaft, the telescopic mechanism and the suction mechanism are located within the accommodating space.

[0011] For example, the storage mechanism includes a base plate and a stop. The base plate has an opening, and the stop is connected to the base plate and extends into the opening in a horizontal direction. The stop is used to support the bottom packaging bag on the storage mechanism. When the telescopic mechanism is in the material picking position, the suction mechanism causes the bottom packaging bag on the stop to pass through the opening and be sucked onto the suction mechanism.

[0012] For example, the storage mechanism also includes a positioning component connected to the base plate, and the stop and the positioning component together form a positioning space for positioning the packaging bag.

[0013] For example, the bag feeding device also includes a pressure plate for dropping the top of the bag onto the storage mechanism.

[0014] For example, the packaging bag feeding device further includes a first detector for detecting whether a packaging bag is present on the storage mechanism; and / or the packaging bag feeding device further includes a second detector for detecting whether a packaging bag is present on the feeding position.

[0015] According to another aspect of the present invention, a packaging device is also provided. The packaging device includes a conveying device and a packaging bag feeding device as described above, wherein the conveying device is used to transport the bottom packaging bag at the feeding position to the target position.

[0016] The packaging bag feeding device provided in this embodiment of the utility model can feed packaging bags by rotating a shaft. Compared with the structure of the prior art, the packaging bag feeding device of this application can be miniaturized and occupies less space, thus making it suitable for scenarios with limited space and thus having strong applicability. Furthermore, the packaging bag feeding device does not require the setting of precise matching structures such as horizontal guide rails, and the structure of the packaging bag feeding device is relatively simple, with low manufacturing cost and good market competitiveness.

[0024] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0025] According to one aspect of the present invention, a packaging bag feeding device is provided. The packaging bag feeding device can feed packaging bags. The packaging bag feeding device can be applied to any suitable equipment, including but not limited to sealing equipment. Therefore, according to another aspect of the present invention, a sealing device is also provided. The packaging bag feeding device and sealing device of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 2 As shown, the packaging bag feeding device may include a mounting frame 100, a storage mechanism 300, and a telescopic mechanism 500.

[0027] The mounting frame 100 can serve as the base for the packaging bag feeding device. The mounting frame 100 can be installed on any suitable platform such as the ground or a workbench. A rotating shaft 210 can be mounted on the mounting frame 100. The rotating shaft 210 is rotatably connected to the mounting frame 100 about a predetermined axis. The rotating shaft 210 can be driven manually or by a rotating shaft drive component 220. Therefore, the packaging bag feeding device may also include a rotating shaft drive component 220. The rotating shaft drive component 220 can be on the mounting frame 100 to drive the rotating shaft 210 to rotate about a predetermined axis. The predetermined axis can be the axis of the rotating shaft 210. In the embodiment shown in the figures, the predetermined axis can be parallel to the horizontal direction; in other embodiments not shown in the figures, the predetermined axis can extend along any other suitable direction.

[0028] The storage mechanism 300 can be used to place the packaging bags 400. The packaging bags 400 can be stacked on the storage mechanism 300 in a vertical direction or any other suitable direction. The packaging bags 400 can be of various types known in the art or that may emerge in the future. For example, the packaging bags 400 can include packaging bags of any suitable shape, such as rectangular bags or round bags; the packaging bags 400 can include packaging bags of any suitable material, such as aluminum bags or plastic bags; the packaging bags 400 can include packaging bags of any suitable type, such as conventional packaging bags or sealed bags. For example, the packaging bags 400 can include rectangular sealed aluminum bags.

[0029] The telescopic mechanism 500 can be mounted on the rotating shaft 210. The drive end of the telescopic mechanism 500 can be connected to a suction mechanism 600. Thus, the telescopic mechanism 500 can drive the suction mechanism 600 to extend away from the rotating shaft 210 and retract towards the rotating shaft 210. The telescopic mechanism 500 can include any suitable telescopic mechanism such as a cylinder or a linear motor.

[0030] The rotating shaft 210 can be used to drive the telescopic mechanism 500 to rotate around a predetermined axis between a picking position and a discharging position. When the telescopic mechanism 500 is in the picking position, it can be used to drive the suction mechanism 600 to pick up the bottom packaging bag from the storage mechanism 300. Specifically, when the telescopic mechanism 500 is in the picking position, it can drive the suction mechanism 600 to extend and approach the bottom packaging bag on the storage mechanism 300. When the distance between the suction mechanism 600 and the bottom packaging bag on the storage mechanism 300 is less than or equal to a preset distance (e.g., touching), the suction mechanism 600 can pick up the bottom packaging bag from the storage mechanism 300 and place it on the suction mechanism 600. Then, the telescopic mechanism 500 can drive the suction mechanism 600 to retract to prevent interference with other components during rotation. The bottom packaging bag refers to the packaging bag stacked on the bottom layer of the storage mechanism 300, which is usually the packaging bag closest to the rotating shaft 210. When packaging bags 400 are stacked vertically on the storage mechanism 300, the bottom packaging bag refers to the lowest packaging bag. When the telescopic mechanism 500 rotates to the feeding position, it can drive the suction mechanism 600 to extend, thereby approaching the feeding position and releasing the bottom packaging bag. Thus, the bottom packaging bag can move to the feeding position by free fall or by being suctioned by a related device. The feeding position can be located on any suitable device, such as a bag opening device or a conveying device. In embodiments where the packaging bag feeding device is applied to the sealing equipment, the sealing equipment may also include a conveying device. The feeding position can be located on the conveying device. When the bottom packaging bag moves to the feeding position, the conveying device can transport the bottom packaging bag to the target position. Thus, a device of the sealing equipment, such as a bag opening device, can perform subsequent processing such as opening the bottom packaging bag at the target position. The conveying device may include a conveyor belt device or a pallet conveyor device. The sealing equipment can achieve automated feeding of packaging bags, and the high degree of automation of the sealing equipment can improve work efficiency. After releasing the bottom packaging bag, the telescopic mechanism 500 can drive the suction mechanism 600 to retract, preventing interference with other components during rotation. In this way, the packaging bag feeding device can complete one packaging bag feeding operation. The rotating shaft 210 can continue to rotate to drive the telescopic mechanism 500 to the picking position again, thus continuing the feeding operation. It should be noted that the rotating shaft 210 can always rotate in the same direction, or it can drive the telescopic mechanism 500 to rotate in the opposite direction to the picking position after driving it to the discharging position.

[0031] In the embodiment shown in the figure, the rotating shaft 210 can drive the telescopic mechanism 500 to rotate 180°, so that the telescopic mechanism 500 can rotate between a picking position and a dispensing position, the picking position being directly above the dispensing position. When the telescopic mechanism 500 is in the picking position, it can drive the suction mechanism 600 to extend upward and retract downward in the vertical direction. The storage mechanism 300 can facilitate the vertical stacking of packaging bags 400. When the telescopic mechanism 500 is in the dispensing position, it can drive the suction mechanism 600 to extend downward and retract upward in the vertical direction. The bottom packaging bag released by the suction mechanism 600 can fall into the loading position by free fall. Of course, in other embodiments, the rotating shaft 210 can also drive the telescopic mechanism 500 to rotate 90°, 120°, or any other suitable angle, so that the telescopic mechanism 500 can rotate between the picking position and the dispensing position.

[0032] In summary, the packaging bag feeding device provided in this embodiment of the present invention can feed packaging bags 400 by rotating the shaft 210. Compared with the structure of the prior art, the packaging bag feeding device of this application can be miniaturized and occupies less space, thus making it suitable for scenarios with limited space and thus having strong applicability. Furthermore, the packaging bag feeding device does not require the setting of precise matching structures such as horizontal guide rails, and the structure of the packaging bag feeding device is relatively simple, with low manufacturing cost and good market competitiveness.

[0033] Exemplarily, the suction mechanism 600 may include a connector 610 and a suction cup assembly 620. The suction cup assembly 620 may include at least one set, such as one set, two sets, or more sets. At least one set of suction cup assemblies 620 may be connected to the connector 610. The connector 610 may include any suitable structure such as a connecting rod or a connecting plate. The drive end of the telescopic assembly 500 may be connected to the connector 610. Each set of at least one set of suction cup assemblies 620 may be used to pick up and release the bottom packaging bag from the storage mechanism 300. At least one set of suction cup assemblies 620 may simultaneously pick up different positions of a bottom packaging bag, thereby increasing the strength of the bottom packaging bag pick-up. Alternatively, each set of suction cup assemblies 620 may pick up one bottom packaging bag, thereby increasing the bag feeding speed of the bag feeding device.

[0034] For example, at least one set of suction cup assemblies 620 may include multiple sets arranged along a predetermined axis. Multiple sets of suction cup assemblies 620 can be used to pick up and release the bottom packaging bags from the storage mechanism 300 in a one-to-one correspondence. This arrangement fully utilizes the space along the predetermined axis of the packaging bag feeding device, thereby increasing the packaging bag feeding speed of the packaging bag feeding device.

[0035] Exemplarily, each suction cup assembly 620 may include a rectangular plate 621 and suction cups 622. A connector 610 may be connected to the rectangular plate 621. The suction cups 622 may be correspondingly positioned at the four corners of the rectangular plate 621. Therefore, four suction cups 622 may be included. The suction cups 622 can be used to pick up and release the bottom packaging bag from the storage mechanism 300. This configuration allows the suction cup assembly 620 to simultaneously pick up different positions of a bottom packaging bag, thereby increasing the strength of the suction. The suction cup assembly 620 is particularly suitable for picking up rectangular packaging bags. Four waist holes 623 may be provided on the rectangular plate 621. The four waist holes 623 may extend from the four corners of the rectangular plate 621 towards the center, correspondingly. The suction cups 622 may be correspondingly positioned on the waist holes 623 and movable along the waist holes 623. Thus, the positions of the four suction cups 622 can be adjusted and adapted according to the shape of the packaging bag 400 to accommodate packaging bags of different sizes.

[0036] Exemplarily, the suction mechanism 600 may also include a vacuum generator 630. The vacuum generator 630 may be mounted on the mounting bracket 100. The vacuum generator 630 may be connected to the air passage of each suction cup 622 to create a negative pressure at the suction end of the suction cup 622. The suction mechanism 600 may also include a pressure detector for detecting the pressure value at which the vacuum generator 630 creates the negative pressure. When the pressure detector detects that the pressure value has not reached a preset threshold, the pressure detector may issue an alarm. This prevents the suction cup 622 from failing to provide sufficient suction force to remove the bottom packaging bag due to insufficient pressure, thus avoiding the bottom packaging bag detaching from the suction cup 622.

[0037] For example, the telescopic mechanism 500 may include multiple, such as two, three, or more, arranged along a predetermined axis. The drive ends of the multiple telescopic mechanisms 500 may be connected to suction mechanisms 600 in a one-to-one correspondence. With this configuration, the multiple telescopic mechanisms 500 can drive the suction mechanisms 600 to suction different positions of a bottom layer packaging bag, thereby increasing the suction strength of the bottom layer packaging bag. Alternatively, each suction mechanism 600 can suction the bottom layer packaging bag separately, thereby fully utilizing the space along the predetermined axis of the packaging bag feeding device and increasing the bag feeding speed of the packaging bag feeding device.

[0038] For example, the storage mechanism 300 may include a plurality of such mechanisms arranged along a predetermined axis. Each storage mechanism 300 may be used to hold a packaging bag 400. In this configuration, the packaging bag feeding device can hold more packaging bags 400. Each storage mechanism 300 may be configured in a one-to-one correspondence with a suction cup assembly 620, so that the suction cup assembly 620 can pick up the bottom packaging bag from its corresponding storage mechanism 300.

[0039] For example, the mounting bracket 100 may include a mounting body 110 and a support assembly 120. The support assembly 120 may be mounted on any suitable platform such as the ground or a workbench. The pivot 210, the storage mechanism 300, and the support assembly 120 may all be mounted on the mounting body 110. The pivot 210 is rotatably connected to the mounting body 110 about a predetermined axis. The pivot drive 220 and the vacuum generator 630 may be mounted on the mounting body 110. The support assembly 120 and the storage mechanism 300 may be located on opposite sides of the mounting body 110. For example, the support assembly 120 may be located on the lower side of the mounting body 110, and the storage mechanism 300 may be located on the upper side of the mounting body 110. The mounting body 110 and the support assembly 120 may enclose a receiving space 130. At least a portion of the pivot 210, the telescopic mechanism 500, and the suction mechanism 600 may be located within the receiving space 130. With this configuration, the mounting body 110 and the support assembly 120 can protect the relevant components within the housing space 130, thereby preventing these components from being damaged by external forces.

[0040] For example, the support assembly 120 may include a connecting plate 121 and a plurality of support columns 122. One end (e.g., the upper end) of each of the plurality of support columns 122 may be connected to the mounting body 110. The connecting plate 121 may be connected to the other end (e.g., the lower end) of at least two of the plurality of support columns 122. The connecting plate 121 may be mounted on any suitable platform such as the ground or a workbench. With this configuration, the support assembly 120 has a simple structure and low manufacturing cost. Furthermore, the connecting plate 121 can connect the plurality of support columns 122 to improve the overall strength of the support assembly 120.

[0041] Exemplarily, the storage mechanism 300 may include a base plate 310 and a stop 320. The base plate 310 may be connected to the mounting body 110. An opening 311 may be provided on the base plate 310. The size of the opening 311 may be adapted to fit the packaging bag 400 to allow the packaging bag 400 to pass through. The stop 320 may be connected to the base plate 310. Furthermore, the stop 320 may extend horizontally into the opening 311. The stop 320 may include a plurality of stops spaced apart along the edge of the opening 311. The stop 320 may be used to support the bottom layer of packaging bags on the storage mechanism 300, thereby supporting all packaging bags 400 stacked on the storage mechanism 300. When the telescopic mechanism 500 is in the picking position, the suction mechanism 600 may pass through the opening 311 to adhere to and suck up the bottom layer of packaging bags; alternatively, the suction mechanism 600 may not pass through the opening 311 to maintain a small distance from the bottom layer of packaging bags, thereby sucking up the bottom layer of packaging bags by vacuum suction force. With this design, the storage mechanism 300 has a relatively simple structure, making it easier to process and manufacture.

[0042] Exemplarily, the storage mechanism 300 may further include a positioning component 330. The positioning component 330 may be connected to the base plate 310. The stop 320 and the positioning component 330 may be closed to form a positioning space 340 for positioning the packaging bag 400. The packaging bag 400 may be stacked on the stop 320 within the positioning space 340. The positioning component 330 may include any suitable structure such as a frame or positioning grippers. The positioning component 330 can position the packaging bag 400, preventing the packaging bag 400 from falling out of its intended position, thereby improving the success rate of the suction mechanism 600 in suctioning the bottom packaging bag.

[0043] For example, the positioning component 330 may include a plurality of positioning posts extending vertically. The lower ends of the positioning posts may be connected to the base plate 310. The positioning posts may be spaced apart along the edge of the opening 311. With this configuration, the structure of the positioning component 330 is relatively simple, and it is convenient for relevant personnel to observe the number of packaging bags 400 in the storage mechanism 300 through the intervals between the positioning posts, so as to facilitate timely replenishment.

[0044] For example, the packaging bag feeding device may also include a pressure plate 350. The pressure plate 350 can be used to place the packaging bags 400 on top of the storage mechanism 300. The pressure plate 350 can be placed within the positioning space 340. By setting the pressure plate 350, the lighter packaging bags 400 can be prevented from falling off the storage mechanism 300 due to external wind or other influences, thereby ensuring that the packaging bags 400 are stably stacked on the storage mechanism 300. When it is necessary to replenish the storage mechanism 300 with packaging bags 400, the relevant personnel can remove the pressure plate 350, and after replenishing the packaging bags 400, the pressure plate 350 will be placed back on top of the packaging bags 400 on the storage mechanism 300.

[0045] For example, the packaging bag feeding device may further include a first detector 710. The first detector 710 may be mounted on the mounting frame 100. The first detector 710 may be used to detect whether a packaging bag 400 is present on the storage mechanism 300. The first detector 710 may be configured one-to-one with the storage mechanism 300. The first detector 710 may include any suitable detector such as an infrared detector. The first detector 710 may be used to detect whether the storage mechanism 300 is short of material. Specifically, when the first detector 710 detects that there is no packaging bag 400 on the storage mechanism 300, relevant personnel can promptly replenish the storage mechanism 300 with packaging bags 400. Furthermore, when the first detector 710 detects that there is no packaging bag 400 on the storage mechanism 300, it can control the rotating shaft drive 220 to stop the rotating shaft 210 from rotating, so as to prevent the suction mechanism 600 from failing to suction the bottom packaging bag. Of course, the first detector 710 may also detect whether the storage mechanism 300 is full. Specifically, when the first detector 710 detects that the maximum number of packaging bags 400 are stacked on the storage mechanism 300, it can control the alarm light and other related components to issue a warning through the controller to prevent relevant personnel from continuing to add materials, which would cause the packaging bags 400 to overflow from the storage mechanism 300.

[0046] Exemplarily, the packaging bag feeding device may also include a second detector (not shown due to angle). The second detector may be mounted on the mounting bracket 100. The second detector can be used to detect whether there is a packaging bag at the feeding position. The second detector may be set one-to-one with the suction mechanism 600. The second detector may include any suitable detector such as an infrared detector. When the suction mechanism 600 releases the bottom packaging bag, if the second detector detects that there is no packaging bag at the feeding position, relevant personnel can control the rotating shaft 210 to stop rotating for maintenance of the packaging bag feeding device. When the second detector detects that there is no packaging bag 400 at the feeding position, it can control the rotating shaft drive 220 to drive the rotating shaft 210 to stop rotating via the controller.
