Description

Technical Field

[0001] This utility model relates to the field of balloon packaging equipment, specifically to a balloon folding and packaging machine. Background Technology

[0002] Balloons are sealed bodies made of latex, used to inflate them with gas for decorative purposes. Large balloons (e.g., over half a meter in diameter when uninflated) are also common in the market. Large balloons are difficult to store and transport; therefore, some large balloons are folded and bagged. However, current bagging is generally done manually. While automated folding packaging machines exist, such as those for disposable gloves, these are for small products. For large balloons, one problem encountered when using folding packaging machines is that separating stacked balloons is difficult due to the large contact area between them. Alternatively, the top layer of balloons may affect the lower layers during transfer, changing their position and impacting subsequent retrieval. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a balloon folding and packaging machine suitable for folding and packaging large-sized balloons.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: A balloon folding and packaging machine includes a feeding mechanism, a folding mechanism, a bagging mechanism, and a sealing mechanism arranged sequentially. The feeding mechanism includes a lifting platform, a lifting unit, a partition unit, and a transfer unit. The lifting platform is used to place stacked balloons. The lifting unit is located above the lifting platform and has a liftable first suction nozzle to pick up the uppermost balloon on the lifting platform. The partition unit includes a first horizontal driver and a first partition. The first partition is located at a height between the first suction nozzle and the lifting platform. The first horizontal driver drives the first partition to slide horizontally to isolate the uppermost balloon on the first suction nozzle from the balloons below. The transfer unit is located between the rear end of the feeding mechanism and the folding mechanism to transfer the uppermost balloon isolated by the first partition to the folding mechanism.

[0005] Furthermore, the width of the first partition is greater than the size of the balloon on the lifting platform.

[0006] Furthermore, the feeding mechanism also includes a pre-separation unit, which includes a second horizontal driver and a second partition. The second partition is located at a height between the first partition and the lifting platform, and the lower side of the second partition has a chamfered surface.

[0007] Furthermore, the folding mechanism includes a multi-stage folding unit, each stage of which includes a linear driver, a push plate, and a limiting plate group. The limiting plate group consists of two parallel limiting plates, with a limiting slit between the two limiting plates. The linear driver drives the push plate to pass through the limiting slit of the limiting plate group.

[0008] Furthermore, in the multi-stage folding unit of the folding mechanism, at least the first-stage folding unit also includes a follower pressure strip, which is set on the moving path of the push plate and is used to press down the balloon on the push plate.

[0009] Furthermore, the follow-up pressure bar is driven to move by a driving device.

[0010] Furthermore, the bagging mechanism includes a bag feeding platform, a bag transferring unit, and a bag filling platform. The bag feeding platform is used to place packaging bags, and the bag filling platform has a guide tongue plate fixed to the output end of the folding mechanism. The bag transferring unit is disposed between the bag feeding platform and the bag filling platform to transfer the packaging bags on the bag feeding platform to the bag filling platform.

[0011] Furthermore, the bag transfer unit has a suction nozzle and a lifting and pressing block. The suction nozzle is used to suck up the upper side wall of the packaging bag. When the lifting and pressing block descends, it presses against the lower side wall of the packaging bag to open the bag opening. The guide tongue plate has a clearance notch corresponding to the lifting and pressing block.

[0012] Furthermore, the bagging platform is equipped with a pushing unit to push the packaging bags on the bagging platform to the sealing mechanism.

[0013] Furthermore, the sealing mechanism includes a transmission unit and an adhesive applicator, a flap structure, and a pressing device arranged sequentially along the transmission direction of the transmission unit.

[0014] The technical solution provided by this utility model has the following beneficial effects: When picking up materials, the first suction nozzle of the lifting unit sucks up and lifts the top balloon. At this time, the first partition moves horizontally under the drive of the first horizontal driver, separating the top balloon from the bottom balloon. Then, the balloon is transferred by the transfer unit. In this way, the top balloon can be transferred without affecting the bottom balloon, achieving stable material picking.

Therefore, they should not be construed as limitations on this utility model.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 6 As shown, this embodiment provides a balloon folding and packaging machine, which includes a feeding mechanism 10, a folding mechanism 20, a bagging mechanism 30, and a sealing mechanism 40 arranged in sequence. The feeding mechanism 10 transfers the balloon 1 to be folded to the folding mechanism 20. The folding mechanism 20 is used to fold the balloon 1 and output it to the bagging mechanism 30. The bagging mechanism 30 puts the folded balloon 1 into the packaging bag 2 and outputs it to the sealing mechanism 40. The sealing mechanism 40 seals the packaging bag 2.

[0020] The feeding mechanism 10 includes a lifting platform 11, a lifting unit 12, a partition unit 13, and a transfer unit 14. The lifting platform 11 is used to place stacked balloons 1. The lifting platform 11 can be raised and lowered, for example, driven by a lifting driver. The lifting unit 12 is located on the upper side of the lifting platform 11. The lifting unit 12 has a first suction nozzle 121 that can be raised and lowered to suck up the uppermost balloon 1 on the lifting platform 11. Similarly, the first suction nozzle 121 is driven to rise and fall by a lifting driver (in this embodiment, a lifting cylinder) to suck up and extract one end (e.g., the front end) of the uppermost balloon 1 on the lifting platform 11.

[0021] The partition unit 13 includes a first horizontal driver and a first partition 131. The first partition 131 is positioned at a height between the first suction nozzle 121 and the lifting platform 11. When the first suction nozzle 121 sucks up and removes one end (e.g., the front end) of the uppermost balloon 1, the first horizontal driver drives the first partition 131 to slide horizontally to isolate the uppermost balloon 1 on the first suction nozzle 121 from the balloons 1 below. Specifically, in the initial position, the first partition 131 is located in front of the balloons 1 on the lifting platform 11. When the front end of the uppermost balloon 1 is lifted, the first horizontal driver drives the first partition 131 to move horizontally from front to back.

[0022] The transfer unit 14 is disposed between the rear end of the feeding mechanism 10 and the folding mechanism 20 to transfer the uppermost balloon 1 isolated by the first partition 131 to the folding mechanism 20.

[0023] The top balloon 1 and the bottom balloon 1 are separated, and then transferred through the transfer unit 14. In this way, the top balloon 1 can be transferred without affecting the bottom balloon 1, thus achieving stable material handling.

[0024] Furthermore, in this embodiment, the width of the first partition 131 is greater than the size of the balloon 1 on the lifting platform 11; thus, the uppermost balloon 1 can be completely isolated from the lower balloon 1.

[0025] Furthermore, the feeding mechanism 10 also includes a pre-separation unit, which includes a second horizontal driver and a second partition 15. The second partition 15 is located at a height between the first partition 131 and the lifting platform 11, and the lower side of the second partition 15 has a chamfered surface 16. When the lifting unit 12 sucks up and lifts one end of the topmost balloon 1, the pre-separation unit acts before the partition unit 13. The specific process is as follows: In the initial position, the second partition 15 and the first partition 131 are on the same side. After the front end of the topmost balloon 1 is lifted, the lower balloon 1 may be lifted synchronously due to electrostatic adsorption or edge connections. At this time, the second horizontal driver drives the second partition 15 to insert under the lifted topmost balloon 1. The beveled surface 16 of the lower side of the second partition 15 makes its insertion end relatively sharp, which can effectively separate the lower balloon 1 that may be lifted together. Through the pre-separation unit, the front end of the topmost balloon 1 is first separated from the lower balloon 1, and then the first partition 13 is used for complete isolation, which makes the operation more reliable.

[0026] Specifically, since the first partition 131 has a large travel distance, the first horizontal actuator can be implemented using a combination of a guide rail and a belt conveyor. The second partition 15 only requires a short insertion stroke; therefore, the second horizontal actuator can be a telescopic cylinder or similar device.

[0027] Of course, in other embodiments, the pre-separation unit structure may not be used.

[0028] Furthermore, in this embodiment, the transfer unit 14 includes a third horizontal driver, a lifting cylinder, and a second suction nozzle. The lifting cylinder is connected to the second suction nozzle. The transfer unit 14 is located at the rear end of the lifting unit 12. When the first partition 131 moves, the lifting cylinder drives the second suction nozzle to descend and suck up the uppermost balloon 1. The third horizontal driver drives the lifting cylinder and the second suction nozzle, i.e. the sucked balloon 1, to drag backward, thereby transferring the balloon 1 to the folding mechanism 20.

[0029] The folding mechanism 20 includes multi-level folding units, such as a four-level folding unit, which folds the balloon four times consecutively. Of course, in other embodiments, it can also be three-level or five-level, etc.

[0030] Each folding unit includes a linear actuator, a push plate 21, and a limiting plate group. The limiting plate group consists of two parallel limiting plates, with a limiting slit 22 between the two limiting plates. The linear actuator can be a device capable of linear drive, such as a cylinder or hydraulic cylinder. The linear actuator drives the push plate 21 to pass through the limiting slit 22 of the limiting plate group.

[0031] When balloon 1 is transferred to folding mechanism 20, the linear actuator of the first-stage folding unit drives the push plate 21 to move upward. The push plate 21 presses against the middle of balloon 1 and moves it upward, performing the first fold during this process. After passing through the limiting slit 22, the folded balloon 1 is effectively limited and shaped. After the first fold is completed, the push plate of the first-stage folding unit retracts; at this time, the linear actuator of the first-stage folding unit drives the push plate 21 to perform the second fold, and so on, thus folding balloon 1 into a small piece. The above structural design of this folding mechanism can be referenced from the structure of a disposable glove.

[0032] Since balloon 1 is relatively large, it is easy to wrinkle when folded. Therefore, more preferably, in the multi-stage folding unit of the folding mechanism, at least the first-stage folding unit also includes a follower pressure strip 23. The follower pressure strip 23 is set on the moving path of the push plate 21 and is used to press down on balloon 1 on the push plate 21. That is, during the first fold, the push plate 21 presses against the middle position of balloon 1 and drives it to move upward, while the follower pressure strip 23 presses down on the push plate 21 and balloon 1 and moves upward together. In this way, by pressing down on the balloon 1 by the follower pressure strip 23, wrinkles are prevented during the folding process.

[0033] Furthermore, preferably, the follower pressure strip 23 is driven by a drive device 24, which better controls the movement of the follower pressure strip 23 and makes it more reliable. When the push plate 21 pushes the balloon 1 against the follower pressure strip 23, the follower pressure strip 23 moves synchronously under the drive of the drive device 24. After the balloon 1 is pushed away by the next folding unit, the follower pressure strip 23 returns to its original position under the drive of the drive device 24.

[0034] The bagging mechanism 30 includes a bag feeding platform 31, a bag transferring unit 33, and a bag filling platform 32. The bag feeding platform 31 is used to place the packaging bag 2. The bag filling platform 32 has a guide tongue 321 fixed to the output end of the folding mechanism 20. The guide tongue 321 is composed of upper and lower tongues. After the last folding unit of the folding mechanism 20 folds the balloon 1, the folded balloon 1 is inserted between the upper and lower tongues of the guide tongue 321 and then exits through the guide tongue 321. The bag transferring unit 33 is located between the bag feeding platform 31 and the bag filling platform 32 to transfer the packaging bag 2 on the bag feeding platform 31 to the bag filling platform 32.

[0035] During bagging, the bag transfer unit 33 transfers the packaging bag 2 from the bag supply platform 31 to the bagging platform 32, and places the bag opening of the packaging bag 2 onto the guide tongue plate 321, that is, the guide tongue plate 321 is inserted into the bag opening of the packaging bag 2; when the last folding unit pushes out the balloon 1, it passes through the guide tongue plate 321 to be accurately inserted into the packaging bag 2.

[0036] Furthermore, the bag transfer unit 33 has a suction nozzle (defined as the third suction nozzle 331) and a lifting and pressing block 332. The third suction nozzle 331 is used to suck up the upper side wall of the packaging bag 2. When the lifting and pressing block 332 descends, it presses against the lower side wall of the packaging bag 2 to open the bag opening of the packaging bag 2. In this way, the packaging bag 2 is transferred in an open manner until it is fitted onto the guide tongue plate 321.

[0037] Since the lifting and pressing block 332 needs to press against the lower side wall of the packaging bag 2 to keep the bag opening of the packaging bag 2 open, in order not to affect the insertion action, the guide tongue plate 321 has a clearance notch corresponding to the lifting and pressing block 332. When the bag opening of the packaging bag 2 is inserted into the guide tongue plate 321, the lifting and pressing block 332 is in the clearance notch of the guide tongue plate 321. In this way, the guide tongue plate 321 and the lifting and pressing block 332 will not interfere with each other.

[0038] Specifically, in this embodiment, the lifting and pressing block 332 consists of a lifting cylinder and a pressing block. The lifting cylinder drives the pressing block to move the pressing block up and down.

[0039] Specifically, in this embodiment, the bag transfer unit 33 also has a translation driver 333, and the third suction nozzle 331 and the lifting and pressing block 332 are both disposed on the translation driver 333. The translation driver 333 drives the third suction nozzle 331, the lifting and pressing block 332 and the packaging bag 2 to transfer.

[0040] Specifically, in this embodiment, in order to ensure that the third suction nozzle 331 and the packaging bag 2 on the bag supply platform 31 can effectively contact each other, the bag supply platform 31 can be set to be height-adjustable; the third suction nozzle 331 can also be set to be height-adjustable.

[0041] Furthermore, a pushing unit is provided on the bagging platform 32 to push the packaging bag 2 to the sealing mechanism 40. Specifically, the pushing unit consists of a pushing cylinder and a pushing plate located on one side of the bagging platform 32. The pushing cylinder is connected to the pushing plate to push the packaging bag 2 to the sealing mechanism 40.

[0042] Specifically, in this embodiment, the packaging bag 2 has an envelope-like structure with a foldable flap 3. The sealing mechanism 40 includes a transmission unit 41 and, sequentially arranged along the transmission direction of the transmission unit 41, an adhesive applicator 42, a flap folding structure 43, and a pressing device 44. After the packaging bag 2 is pushed into the sealing mechanism 40, it is transported by the transmission unit 41. During this process, the adhesive applicator 42 applies adhesive to the packaging bag 2. Then, the flap folding structure 43 folds the flap 3 of the packaging bag 2. Finally, the pressing device 44 presses down the folded flap 3, thus bonding and fixing the flap 3, thereby sealing the packaging bag 2.

[0043] Specifically, the transmission unit 41 employs a two-layer belt transmission device, with the upper and lower belts clamping and transmitting the packaging bag; the glue applicator 42 is connected to a glue supply device 45; the flap structure 43 is a guide plate inclined to the transmission direction; and the pressing device 44 also employs a two-layer belt transmission device, with the upper and lower belts pressing the folded flap 3 together with the packaging bag body, thus bonding and fixing the flap 2. Of course, in other embodiments, the structure of each unit of the sealing mechanism 40 is not limited to this, or the sealing mechanism 40 may directly adopt a heat-sealing structure according to the type of packaging bag 2, etc.

[0044] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
