Description

Technical Field

[0002] The bagging automatic packaging machine is a commonly used packaging equipment. It usually stacks several packaging bags of raw materials in the bag storage part of the equipment, and then automatically takes out the packaging bags one by one from the bag storage part through the bag taking mechanism. It then performs the operations of bag opening, filling, sealing and discharging in sequence, and finally obtains the finished bag filled with materials and sealed.

[0003] In the prior art, a commonly used bagging packaging machine is one in which the packaging bag mounted on the clamp is in a state in which the bag opening faces horizontally, and the material is pushed into the packaging bag horizontally by a pushing mechanism, and the packaging bag is separated from the clamp by the continued advancement of the pushing mechanism to enter the heat sealing station horizontally. The packaging bag filled with material is placed flat on the support platform of the heat sealing station with the bag opening facing horizontally. After the packaging bag is filled, the lower bag surface of the packaging bag will be in a flat state due to the support of the supporting platform below, and the upper bag surface of the packaging bag will be supported by the internal material and arched, resulting in the upper bag surface and the lower bag surface being misaligned at the bag opening. In this way, it is difficult to heat-seal the bag openings together flush during heat sealing, which affects the heat sealing quality and sealing effect. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a packaging bag conveying mechanism to solve the problem that the conveying mechanism of the existing bagging packaging machine is misaligned when the packaging bag is laterally conveyed to the next station after filling, which is not conducive to packaging.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] The path segment of the guide path one corresponding to the flipping movable segment of the frame is flipping guide segment one, and the path segment of the guide path two corresponding to the flipping movable segment of the frame is flipping guide segment two. The distance between the flipping guide segment one and the flipping guide segment two changes along the direction of travel so that the frame can flip during travel.

[0011] In a possible implementation, the tail sections of the flip guide section 1 and the flip guide section 2 are respectively provided with rising sections to raise the height of the frame.

[0012] In a possible implementation, the first flip guide segment and / or the second flip guide segment presents a curved path.

[0016] The clamping parts are movably mounted on the frame, and the two clamping parts are driven by a driving component to move relative to each other so as to adjust the distance between the two clamping parts.

[0017] In a possible implementation, the clamps are arranged in multiple groups side by side on the frame, and the side-by-side direction is perpendicular to the moving path of the frame.

[0018] In a possible implementation, the frame is further provided with a support portion for lifting the packaging bag.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0034] Please refer to Figure 1 and Figure 2 As shown, a packaging bag conveying mechanism includes a frame 3, a clamp, an actuator 2 and a driving mechanism 1. The frame 3 is provided with a clamp for clamping the packaging bag 10, and a guide path 1 6 and a guide path 2 7 are provided between station 1 and station 2. The frame 3 is rotatably connected to the actuator 2, and the frame 3 is provided with a guide portion 1 8 that moves along the guide path 1 6. The actuator 2 is provided with a guide portion 2 9 that moves along the guide path 2 7. The driving mechanism 1 drives the actuator 2 to move along the guide path 2 7 to drive the frame 3 to move.

[0035] The packaging bag conveying mechanism is primarily used to convey, including but not limited to, loaded packaging bags 10 between two workstations, Station 1 and Station 2. The packaging bags 10 can be clamped to the frame 3 using a clamp and are moved and flipped accordingly by the frame 3. Guide path 1 6 and guide path 2 7 work together. Guide path 1 6 primarily guides the frame 3, specifically by means of its guide portion 1 8 cooperating with guide path 1 6 for positioning. Guide path 2 7 primarily guides the actuator 2, which moves along guide path 2 7 via guide portion 2 9. Actuator 2 is connected to the drive mechanism 1 so that it can move along guide path 2 7 under external force, while also driving the frame 3. Furthermore, under the guidance of guide paths 1 6 and 2 7, it facilitates translation and flipping. Actuator 2 moves along guide path 2 7, effectively performing irregular motion, with the actuator 2 moving along guide path 2 7 and driving the frame 3.

[0036] Please refer to Figure 3 and Figure 4As shown, since the actuator 2 is rotatably connected to the frame 3, the frame 3 can be flipped by rotation, and since a guide portion 1 8 is provided on the frame 3, the distance between the two paths 1 and at least part of the guide path 2 7 can be gradually increased or decreased, so that the distance between the guide portion 1 8 and the guide portion 2 9 can be changed. Since the actuator 2 and the frame 3 are rotatably connected, the connection point of the actuator 2 and the frame 3 can be rotated around the guide portion 1 8 through the actuator 2 when the distance changes, and the actuator 2 can rotate relative to the frame 3 with the connection point as the rotation center, so that the packaging bag 10 on the frame 3 can be flipped from one posture or orientation to another posture or orientation, such as from horizontal to vertical.

[0037] Based on this, in order to achieve the conveying method of first translation and then flipping, please continue to refer to Figure 3 and Figure 4 As shown, in an embodiment of the present application, the movement process of the frame 3 from station one to station two can sequentially include a translation movement section and a flipping movement section, wherein the frame 3 maintains a first posture and moves in a straight line in the translation movement section, and flips to a second posture during the movement in the flipping movement section. By setting the shape paths of the guide path 1 6 and the guide path 2 7, when the actuator 2 moves along the guide path 2 7 and drives the frame 3 to move along the guide path 1 6, the height of the connection point between the frame 3 and the actuator 2 relative to the guide portion 1 8 can be adjusted, thereby adjusting the posture of the frame 3, causing the frame 3 to flip, and further adjusting the posture of the packaging bag clamped on the frame 3, so that the packaging bag originally with the bag opening facing horizontally can be flipped to a bag opening facing vertically.

[0038] The rack 3 with the packaging bag 10 clamped thereon can first perform a translational movement. When the rack 3 is in the first posture, the packaging bag 10 on the rack 3 is in a state where the bag opening is facing horizontally. For the bag-type packaging machine, the material is pushed horizontally into the packaging bag mounted on the bag-covering clamp. The packaging bag mounted on the bag-covering clamp is in a state where the bag opening is facing horizontally. The rack 3 first maintains the first posture and moves in a straight line, which means that the packaging bag clamped by the clamping member 4 on the rack 3 is kept in a state where the bag opening is facing horizontally and exits from the bag-covering clamp along a horizontal straight line, thereby ensuring that the packaging bag can be smoothly separated from the bag-covering clamp, and avoiding damage to the packaging bag due to interference or obstruction of the bag-covering clamp. Then the rack 3 is flipped to the second posture in the flipping activity section. When the rack 3 is in the second posture, the packaging bag 10 on the rack 3 is in a state where the bag opening is facing vertically. In this way, the flipping and conveying between the workstation 1 and the workstation 2 can be realized, and the packaging bag 10 is flipped to a posture with the bag opening facing upwards by flipping for the subsequent heat sealing process.

[0039] In some application scenarios, the conveying mechanism can be used in other processes in the packaging equipment that require first translation and then flipping to change the posture, and can be configured according to actual needs. Preferably, the first posture is a horizontal posture, and the second posture is an upright posture, so that after loading in a horizontal posture, it can first be translated and separated from the loading station, and then flipped during the movement to switch to an upright posture. In the upright posture or a posture close to the upright posture, the bag opening of the packaging bag 10 can be flush, so that it can better facilitate the heat sealing of the heat sealing station, avoiding the problem of bag opening misalignment in horizontal heat sealing that affects the heat sealing quality and sealing effect. Of course, station one and station two can also be stations with other different functions in other scenarios. The specific configuration can be selected according to actual needs and is not limited.

[0040] Please refer to Figure 3 and Figure 4 As shown, in one embodiment, the tail section of the flipping movable section is a lifting movable section, and the height of the frame 3 is raised in the lifting movable section.

[0041] In this way, the packaging bag 10 is initially flipped over by the flipping guide section and then lifted up to a certain height, which can also provide the frame 3 with more rotation space and further rotate around the guide portion 8, thereby enabling the frame 3 to flip 90° and the packaging bag 10 to flip from a horizontal posture to a vertical posture, thereby improving the accuracy of transportation.

[0042] For example, when the second station is the heat sealing station, since heat sealing is performed in an upright position, the heat sealing mechanism is located at the top and the heat sealing port is a clampable structure that moves up and down by a cylinder. After the packaging bag 10 is flipped to an upright state, its bag opening faces the heat sealing port at the top. The heat sealing mechanism moves downward so that the bag opening enters the heat sealing port, and then heat sealing can be performed by clamping.

[0043] In order to make the guide path 1 6 and the guide path 2 7 match the movement process of the frame 3 from the station 1 to the station 2, please refer to Figure 3-5 As shown, in an embodiment of the present application, the path segment of the guide path 16 corresponding to the translational active segment of the frame 3 is a translational guide segment 161, and the translational guide segment 161 is parallel to the straight-line travel direction of the frame 3 maintaining the first posture; the path segment of the guide path 16 corresponding to the flipping active segment of the frame 3 is a flipping guide segment 162, and the path segment of the guide path 27 corresponding to the flipping active segment of the frame 3 is a flipping guide segment 272, and the distance between the flipping guide segment 162 and the flipping guide segment 272 changes along the travel direction to enable the frame 3 to flip during the travel process.

[0044] The guide path 16 mainly includes a translation guide segment 161 and a flip guide segment 162. The translation guide segment 161 and the flip guide segment 162 correspond to the path segments of the translational active segment of the frame 3, namely the translation guide segment 161 and the flip guide segment 162, respectively. Correspondingly, the guide path 27 also mainly includes a flip guide segment 272. The flip guide segment 272 corresponds to the path segment of the flip active segment of the frame 3. In this way, the translation guide segment 161 can provide guidance for the translation of the frame 3, so that the frame 3 can be translated to the flip guide segment 162. When entering the flip guide segment 162, since the distance between the flip guide segment 162 and the flip guide segment 272 changes along the travel direction, such as the distance gradually increases or decreases, the actuator 2 can drive the connection point of the rotational connection between the actuator 2 and the frame 3 to rotate around the guide portion 18, thereby enabling the frame 3 to flip during the travel process.

[0045] Furthermore, the tail sections of the flip guide section 1 62 and the flip guide section 2 72 are respectively provided with rising sections to raise the height of the frame 3 .

[0046] In this way, the ascending section of guide path 1 6 is ascending section 1 63, and the ascending section of guide path 2 7 is ascending section 2 73. Ascending section 1 63 and ascending section 2 73 cooperate to match the lifting section. After the initial flip, the further extension of the ascending section allows the angle between guide section 1 and the actuator to be increased, thereby facilitating the frame to rotate around guide section 1 to a greater angle. Furthermore, further lifting allows the packaging bag to be further flipped to an upright position, further facilitating heat sealing with both sides of the bag opening flush. Specifically, ascending section 1 63 and ascending section 2 73 bend in the same direction and both face in the same direction. Ascending section 2 73 extends in the same direction as flipping guide section 2 72.

[0047] Please refer to Figure 7-9 As shown, in the preferred embodiment of the guide path 1 6 and the guide path 2 7, the flipping guide segment 1 62 and / or the flipping guide segment 2 72 are curved paths. By having one or both of them be curved paths, a guide structure with a spacing that varies along the direction of travel of the frame 3 can be constructed, thereby realizing the flipping of the frame 3.

[0048] For example, when the flip guide segment 1 62 is a curved path, the flip guide segment 2 72 can be a curved path or a straight path, and vice versa; when the flip guide segment 1 62 is a curved path and the flip guide segment 2 72 is a curved path, the flip guide segment 1 62 and the flip guide segment 2 72 gradually approach or move away from each other along the moving direction of the frame 3, wherein when they gradually approach, the actuator 2 is transmitted at the bottom, and when they gradually move away, the guide path 2 7 is located above the guide path 1 6 and the actuator 2 is transmitted at the top.

[0049] During specific implementation, guide path 2 7 also includes a translation guide segment 2 71 , which corresponds to the translational movement segment of frame 3 during its travel. The translation guide segment 1 61 of guide path 1 6 and the translation guide segment 2 71 of guide path 2 7 are used to guide the translation of frame 3. When actuator 2 moves along translation guide segment 2 71 of guide path 2 7 , the translation guide segment 1 61 is parallel to the translation direction of frame 3, allowing frame 3 to maintain its unchanged translational posture and escape from station 1. The spacing between flip guide segment 1 62 and flip guide segment 2 72 varies, specifically gradually decreasing or increasing from the end closest to station 1 to the end closest to station 2. This progressive change in spacing allows actuator 2 to drive the connection point to rotate around guide portion 1 8, causing the flip frame to flip. By first translating and then flipping the packaging bag 10, the packaging bag 10 can effectively leave the first station. Then, during the movement, the packaging bag 10 can be flipped by rotating, thereby turning the packaging bag 10 from a horizontal position to a nearly vertical position. The opening of the packaging bag 10 is thus flush and suitable for heat sealing or other operations. Of course, each guide path of the guide path 1 6 and the guide path 2 7 has a smooth transition between them.

[0050] The shape matching of the above-mentioned guide path 1 6 and guide path 2 7 can be combined into a variety of different structures. The arc size or curvature of the path segment and the change in the spacing between guide path 1 6 and guide path 2 7 can be adaptively configured according to the convenience of rotation to the upright state, without any restriction.

[0051] In the embodiment of the present application, the driving mechanism 1 includes a driving member 11 and a power mechanism. The actuating member 2 is slidably connected to the driving member 11. The driving member 11 is driven by the power mechanism to move linearly or rotationally.

[0052] The actuator 2 is slidably connected to the driving member 11 to form a retractable component. In this way, the actuator 2 can be flexibly extended and retracted when it moves along the guide path 7, and overcome the problem of insufficient length when connected to the power mechanism during the distance change. The driving member 11 can be driven by the power mechanism to move linearly, combined with Figure 10 As shown, for example, the driving member 11 is linearly driven by the electric guide rail 200 or the screw-nut pair mechanism to move the actuator 2 along the guide path 2 7. At this time, the translation guide segment 2 71 is a straight segment. In addition, the driving member 11 can also be rotated. For example, the actuator 2 rotates around a rotation axis, and the power mechanism drives it to rotate around the rotation axis. Through such a rotation method and the retractable structure, it can be translated and flipped along the guide path 2 7. At this time, the translation guide segment 2 71 is not parallel to the translation guide segment 1 61 and moves irregularly. Therefore, the translation guide segment 2 71 needs to be configured as a curved path that matches the motion trajectory of the guide part 2 9.

[0053] Preferably, the driving member 11 is rotatably arranged, and the actuating member 2 is slidably connected to the driving member 11 along the radial direction of the rotational circumference of the driving member 11. The driving member 11 can rotate about an axial direction, and the actuating member 2 can slide along the radial direction of the rotational circumference of the driving member 11, so that the frame 3 can be translated and flipped by sliding engagement while rotating.

[0054] For details, please refer to Figure 1 As shown, the driving member 11 rotates the connecting member on the rotating shaft 12, and the power mechanism drives the rotating shaft 12 to rotate, and the power mechanism may include a pull rod 13, a rotating shaft 15, a swing arm 14, a reducer 16 and a motor 17. The motor 17 is driven by the reducer 16, and the reducer 16 is passed through the rotating shaft 15 and drives the rotating shaft 15. A swing arm 14 is provided on the rotating shaft 15, and the swing arm 14 is hinged to the driving member 11 through the pull rod 13, so that the driving member 11 can be driven to rotate under the drive of the motor 17.

[0055] Furthermore, to facilitate rotation and reversal of the frame 3 along the path, the guide portion 1 8 includes a movable member 1. Eccentric connectors 82 are fixed to both ends of the frame 3. The frame 3 is rotatably connected to the actuator 2 via the eccentric connectors 82. The movable member 1 is positioned eccentrically of the eccentric connectors 82 and moves along the guide path 1 6. Thus, by varying the spacing between the reversible guide segment 1 62 and the reversible guide segment 2, the frame 3 or the connection point between the frame 3 and the actuator 2 can be rotated and reversed about the movable member 1. The reversible guide path 1 6 also facilitates positioning the movable member 1 in a position conducive to eccentric transmission. Specifically, the movable member 1 is a bearing 1 81, which flexibly engages with the guide path 1 6 provided in the guide groove structure of the guide plate 5. Accordingly, the guide portion 2 9 of the actuator 2 is the movable member 2, which is a bearing 2 91, which flexibly engages with the guide path 2 7.

[0056] In order to clamp both sides of the bag opening and close the bag opening before heat sealing, please combine Figure 6 As shown, the clamp includes two clamping members 4 arranged in pairs, and the two clamping members 4 are respectively used to clamp one side of the packaging bag 10; the clamping members 4 are movably mounted on the frame 3, and the two clamping members 4 are driven by a driving member to move relative to each other to adjust the distance between the two clamping members 4.

[0057] The clamping member 4 may be a pneumatic clamping member 4, whose clamping opening allows both sides of the bag opening of the packaging bag 10 to pass through during the translation process of the packaging bag conveying mechanism when resetting, so that both sides of the bag opening are located within the clamping opening of a clamping member 4, thereby clamping the packaging bag 10. The clamping members 4 can move relative to each other under the drive component 1. In this way, before heat sealing, the bag opening can be flattened and straightened by adjusting the spacing between the clamping members 4, thereby closing the bag opening and facilitating heat sealing, and preventing wrinkles on the bag opening from affecting the sealing and aesthetics. Specifically, the drive component 1 may be the electric guide rail 2 100.

[0058] In order to realize multi-station transportation, further, the clamps are provided in multiple groups side by side on the frame 3 , and the side-by-side direction is perpendicular to the moving path of the frame 3 .

[0059] Furthermore, the frame 3 is provided with a support portion 300 for lifting the packaging bag 10. The support portion 300 includes a support member fixed to the frame 3 and located between a set of clamping members 4. This allows the loaded packaging bag 10 to be lifted so that the packaging bag 10 can be stably translated and flipped. When the frame 3 just receives the loaded packaging bag 10, it is in a first posture, with the bag opening of the packaging bag 10 facing horizontally. Without the support portion 300, the packaging bag 10 would sag due to the weight of the material, causing the entire packaging bag 10 to become bent, resulting in creases and other undesirable conditions in the packaging bag, which is not conducive to the stability of conveying the loaded packaging bag 10.

[0060] The above are merely preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the claims. Persons skilled in the art will appreciate that improvements and modifications may be made without departing from the spirit and scope of the present invention, and such improvements and modifications shall also be considered within the scope of protection of the present invention.
