Description

Technical Field

[0001] This utility model relates to a packaging unpacking machine, and more particularly to a small bag unpacking machine. Background Technology

[0002] Packaging unpacking machines are mainly used in the plastics, rubber, food, pharmaceutical, and chemical industries, especially for unpacking and unloading small bags of dry powdery or granular materials such as food additives, which can greatly improve production efficiency. However, traditional small bag unpacking machines typically place the packaging bags on a conveyor belt, which then transports them to the cutting area. A rotating cutter then cuts the bags to unload them. This method may still result in some material remaining inside the bag, failing to achieve complete material removal.

[0003] CN106081283A discloses a packaging unpacking machine and its unpacking process. The packaging unpacking machine includes a frame, a feeding platform on one side of the frame, a feeding belt on the feeding platform, a receiving plate at the outlet of the feeding belt, a set of blades on the receiving plate, a gripping table above the receiving plate, a slider connected to the gripping table, a slide rail on the frame, the slider on the slide rail, a set of gripping rods on the gripping table, and gripping plates connected to the gripping rods. However, the above solution has the following defects: (1) it still cannot solve the technical problem of completely unloading the material; (2) setting multiple blades in combination with saw blades to cut the material bag to break the bag can easily cause foreign objects to enter the material during cutting, thereby contaminating the material. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a small bag unpacking machine with less residual material, faster feeding speed, and reduced pollution.

[0005] The technical solution of this utility model is: a small bag unpacking machine, including a frame, an unpacking and unloading conveyor line disposed within the frame, and a transfer gripping mechanism disposed above the unpacking and unloading conveyor line; the transfer gripping mechanism includes a gripping component, a lifting mechanism for controlling the lifting and lowering of the gripping component, and a translation mechanism for driving the gripping component and the lifting mechanism to move laterally together; the gripping component includes at least two wing plates hinged to the lower end of the lifting mechanism, a wing plate drive part for driving the wing plates to flip, and an adsorption device disposed on the wing plates.

[0006] Furthermore, the unpacking and unloading conveyor line includes a packaging bag conveying section, a material collection section, and a waste bag recycling conveyor section arranged sequentially along the packaging bag conveying path.

[0007] Furthermore, the inner side of the material collection section is provided with a bag-breaking knife, and the bag-breaking knife is located on the side closer to the packaging bag conveying section, so that the packaging bag moves laterally and breaks under the drive of the transfer gripping mechanism.

[0008] Furthermore, the bag-breaking knife has a single-blade structure, and the cutting depth exceeds 1 / 2 of the overall thickness of the packaging bag.

[0009] Furthermore, the lifting mechanism includes a first lifting frame and a servo cylinder for driving the first lifting frame to rise and fall; the lower end of the first lifting frame is provided with a base plate, and the two sides of the base plate are hinged with rotatable wing plates, and the bottom surfaces of the base plate and the wing plates are provided with adsorption devices; or the lifting mechanism includes a second lifting frame and a servo cylinder for driving the second lifting frame to rise and fall; the lower end of the second lifting frame is provided with a vertical plate, the bottom of the vertical plate is connected to a rotating shaft, two horizontally arranged wing plates are sleeved on the rotating shaft, and the wing plates can rotate along the rotating shaft, and the bottom surfaces of the wing plates are provided with adsorption devices.

[0010] Furthermore, the translation mechanism includes a movable slide and a motor transmission mechanism; the movable slide is mounted on the frame, the servo cylinder is fixed on the slider of the movable slide, and the motor transmission mechanism can drive the slider to move laterally along the movable slide.

[0011] Furthermore, the first lifting frame includes the base plate and multiple guide rods connected between the base plate and the slider, and the guide rods and the slider are slidably connected; the piston rod end of the servo electric cylinder is connected to the base plate.

[0012] Furthermore, the second lifting frame includes a push plate, a connecting plate, the vertical plate, and multiple guide rods connected between the push plate and the slider; the guide rods are slidably connected to the slider; the piston rod end of the servo electric cylinder is connected to the push plate; the connecting plate is located below the push plate and is integrated with the push plate through a connector; the vertical plate is vertically connected to the bottom surface of the connecting plate, and a reinforcing structure is provided between the vertical plate and the connecting plate.

[0013] Furthermore, the waste bag recycling and conveying unit is a belt conveyor or a roller conveyor, and a waste bag recycling bin is provided on the belt conveyor or roller conveyor; or the waste bag recycling and conveying unit is a transport trolley.

[0014] Furthermore, the frame is an integrally sealed structure; the material collection section is a material collection hopper, and a bag-breaking knife support is provided inside the material collection hopper, with the bag-breaking knife mounted on the bag-breaking knife support.

[0015] The beneficial effects of this utility model are:

[0016] (1) The gripping component adopts a rotatable wing plate and an adsorption device, which can repeatedly shake the packaging bag adsorbed on the suction cup to shake off the material remaining in the packaging bag. Moreover, the wing plate can drive the packaging bag to bend by flipping, opening the broken material opening to the maximum to facilitate material discharge; non-destructive bag gripping, and no foreign objects will be introduced during the bag gripping process.

[0017] (2) The packaging bag moves laterally under the drive of the translation mechanism. When the packaging bag moves from one side of the hopper to the other side, it is broken laterally, and the feeding speed is increased with the help of the wing plate flipping.

[0018] (3) The bag-breaking knife is a single blade, and the cutting depth exceeds 1 / 2 of the thickness of the packaging bag. This ensures that the packaging bag is cut through on one side. Moreover, the single cut can control the foreign objects generated during cutting to the maximum extent, preventing the packaging bag from breaking and generating more fragments or debris that fall into the collection hopper.

[0019] (4) The overall structure is compact, with few components and a small footprint, making it particularly suitable for unpacking, unloading and transporting small packaging bags. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figures 1-4 As shown: A small bag unpacking machine includes a frame 1, an unpacking and unloading conveyor line disposed within the frame 1, and a transfer and gripping mechanism 2 disposed above the unpacking and unloading conveyor line; the unpacking and unloading conveyor line includes a packaging bag conveying platform 3, a collection hopper 4, and a waste bag recycling conveyor platform 5 arranged sequentially along the conveying path of the packaging bags 9.

[0038] In this embodiment, the frame 1 is designed with at least two layers, preferably two layers, including a lower frame and an upper frame. The bottom of the lower frame is provided with support legs. The lower frame is used to house the packaging bag conveying platform 3, the collection hopper 4, and the waste bag recycling conveying platform 5. The transfer and gripping mechanism 2 is installed on top of the lower frame, and the upper frame is used to cover the entire transfer and gripping mechanism 2. The entire frame 1 is preferably designed as an integrally sealed structure, that is, a panel is provided on the frame to prevent dust from overflowing.

[0039] In this embodiment, the packaging bag conveying platform 3 can be a belt conveyor or a roller conveyor. The packaging bag conveying platform 3 is located on one side of the lower layer of the frame. The frame 1 may not have a panel on this side, allowing the packaging bag conveying platform 3 to connect with the external conveyor line to facilitate the delivery of packaging bags from the outside into the frame. Alternatively, the frame may have an openable door on this side, such as an automatically / manually opening lifting door or a tilting door, to maintain the overall airtightness of the frame.

[0040] In this embodiment, the collecting hopper 4 is installed on the lower layer of the frame 1, located between the packaging bag conveying platform 3 and the waste bag recycling conveying platform 5. A bag-breaking knife support 61 is provided inside the collecting hopper 4, and a bag-breaking knife 6 is mounted on the support 61. The bag-breaking knife 6 is fixedly connected to one side of the support 61, specifically the side closer to the packaging bag conveying platform 3. When the packaging bag moves from one side of the collecting hopper 4 to the other, the bottom of the packaging bag is cut open by the bag-breaking knife, completing the unloading process. It is understood that the bag-breaking knife 6 is preferably a single blade with its tip pointing upwards, forming a sharp structure for cutting the packaging bag. The bottom of the collecting hopper 4 is provided with a discharge port 41 to facilitate material output. Preferably, the bottom of the discharge port 41 uses negative pressure suction to prevent dust overflow during discharge, reducing material loss and environmental pollution.

[0041] In this embodiment, the waste bag recycling conveyor platform 5 can be a belt conveyor or a roller conveyor. The waste bag recycling conveyor platform 5 is equipped with a waste bag recycling bin 51. When the waste bag recycling bin 51 is full, the waste bag recycling conveyor platform 5 removes the waste bag recycling bin 51 from the frame for waste bag recycling. The waste bag recycling conveyor platform 5 is located on the other side of the lower layer of the frame. The frame 1 may not have a panel on this side, allowing the waste bag recycling conveyor platform to connect with the external conveyor line; alternatively, the frame may have an openable door on this side, such as an automatically / manually opening lifting door or a tilting door, to maintain the overall airtightness of the frame. Furthermore, the position of the waste bag recycling conveyor platform 5 is lower than the conveyor platform 3 inside the packaging bags, ensuring that the waste bag recycling bin 51 is flush or nearly flush with the collection hopper 4, facilitating the smooth movement of the transfer and gripping mechanism 2 within the reserved space.

[0042] In this embodiment, the transfer gripping mechanism 2 includes a gripping component 23, a lifting mechanism 22 for controlling the lifting and lowering of the gripping component, and a translation mechanism 21 for driving the gripping component 23 and the lifting mechanism 22 to move laterally together.

[0043] Specifically, the translation mechanism 21 includes a movable slide 211, a drive motor 212, a reducer 213, and a transmission belt 214. The movable slide 211 is mounted on the top of the lower frame, and the drive motor 212 and reducer 213 are mounted on one end of the movable slide 211. The output shaft of the drive motor 212 is connected to the input shaft of the reducer 213 via a coupling. The output shaft of the reducer 213 is connected to a driving synchronous pulley. At the other end of the movable slide 211, a fixed seat is provided at a position opposite to the driving synchronous pulley. A driven synchronous pulley is provided in the fixed seat. The driving synchronous pulley is connected to the driven synchronous pulley via the transmission belt 214. The lower side of the transmission belt 214 is fixedly connected to the upper surface of the slider 215 of the movable slide via spaced threaded connectors.

[0044] The lifting mechanism 22 includes a servo cylinder 221 and a first lifting bracket 222. The servo cylinder 221 is mounted on the slider 215 of the movable slide table. The first lifting bracket 222 includes a base plate 2221 and four guide rods 2222 connected between the base plate and the slider, and the four guide rods 2222 are slidably connected to the slider 215. The piston rod end of the servo cylinder 221 is connected to the base plate 2221, which can drive the base plate 2221 to move up and down. The four guide rods 2222 can extend and retract along the slider 215 during the lifting of the base plate 2221 to improve the stability of the lifting mechanism 22.

[0045] The gripping component 23 includes wing plates 231 hinged to both sides of the lower part of the first lifting frame 222, a cylinder 232 for controlling the rotation of the wing plates 231, and suction cups 233 disposed on the wing plates 231 and the bottom surface of the first lifting frame 222. A cylinder mounting seat is fixed to the inner surface of the base plate 2221 of the first lifting frame 222. The cylinder body of the cylinder 232 is fixedly connected to the cylinder mounting seat, and the piston rod end of the cylinder 232 is hinged to the inner surface of the wing plate 231. The hinge connection can be achieved through a spherical bearing or a pin. The two wing plates 231 are symmetrically disposed on both sides of the lower part of the first lifting frame. Both the base plate 2221 and the wing plates 231 of the first lifting frame are designed as groove-shaped structures with concave cavities. The two ends of the wing plates 231 are hinged to the two sides of the first lifting frame 222 via connectors. At least one suction cup 233 is provided on the bottom surface of both wing plates 231 and the bottom surface of the base plate 2221 of the first lifting frame.

[0046] In this embodiment, a tension and pressure sensor 7 can also be provided between the piston rod of the servo electric cylinder 221 and the base plate 2221 to detect the thrust and tension output by the servo electric cylinder 221, so as to ensure that it always stays within the set range and avoids overload or impact of the servo electric cylinder, thereby improving the motion accuracy and stability of the servo electric cylinder.

[0047] In this embodiment, the entire conveying path of the packaging bag within the frame 1 is a transverse conveying and transverse movement for bag breaking. The upward flipping of the wing plates 231 on both sides causes the packaging bag to bend, opening the material opening to its maximum for easy unloading. Furthermore, the bag breaking process uses a single blade, with a cutting depth exceeding half the overall thickness of the packaging bag, ensuring a complete cut on one side. This single cut also maximizes control over foreign matter generated during cutting, preventing further fragments or debris from falling into the collection hopper.

[0048] The workflow of this embodiment includes the following steps:

[0049] S101: After the packaging bag 9 is transported to the gripping position of the packaging bag conveying platform 3, the moving slide 211 drives the lifting mechanism 22 together with the gripping component 23 to move above the gripping position of the packaging bag. Then, the servo cylinder 221 controls the first lifting frame 222 to press down onto the surface of the packaging bag. The suction cup 233 set on the bottom plate 2221 of the first lifting frame adsorbs the packaging bag. After being lifted to a certain height, it moves to the next work station.

[0050] S102: The packaging bag moves from one side of the collecting hopper 4 to the other side with the moving slide 211. During the movement, the bottom of the packaging bag is cut open by the bag-breaking knife, and the material is discharged from the collecting hopper 4.

[0051] S103: While the packaging bag is being fed, the wing plate 231 is controlled by the cylinder 232 to rotate and adsorb the packaging bag. Then, driven by the cylinder 232, the packaging bag adsorbed on the suction cup 233 is repeatedly shaken to shake off the material remaining in the packaging bag.

[0052] S104: After the material is unloaded, the moving slide 211 moves the waste bag to the top of the waste bag recycling bin 51. The suction cup 233 releases the pressure, and the waste bag automatically falls into the waste bag recycling bin 51. The wing plate 231 retracts, and the servo cylinder 221 controls the bottom plate 2221 of the first lifting frame to repeatedly press the waste bag that has fallen into the waste bag recycling bin 51 to ensure that the waste bag in the waste bag recycling bin 51 is flat and does not overflow. After the packaging bag in the waste bag recycling bin 51 is full, it is output by the waste bag recycling conveyor platform 5.

[0053] Example 2

[0054] like Figures 5-10 As shown: The difference from Embodiment 1 is that the frame 1 is preferably configured as a three-layer structure, including a lower frame, a middle frame, and an upper frame. The waste bag recycling conveying platform 5 is replaced by a wheeled transport trolley 8, which is located within the lower frame and extends into the middle frame. The discharge port 41 of the collection hopper 4 extends into the lower frame. The frame 1 is designed as a completely enclosed structure. Furthermore, the transfer and gripping mechanism differs from that of Embodiment 1.

[0055] Specifically, the transfer gripping mechanism includes a gripping component, a lifting mechanism for controlling the lifting and lowering of the gripping component, and a translation mechanism for driving the gripping component and the lifting mechanism to move laterally together. The translation mechanism has the same structure as in Embodiment 1, and will not be described in detail here. The lifting mechanism includes a servo cylinder 221 and a second lifting bracket 223; the servo cylinder 221 is mounted on the slider 215 of the movable slide. The second lifting bracket 223 includes a push plate 2231, a connecting plate 2232, a vertical plate 2233, a bellows cover 2234, and four guide rods connecting the push plate 2231 and the slider 215. Four guide rods are slidably connected to the slider 215; the piston rod end of the servo cylinder 221 is connected to the push plate 2231, which can drive the push plate 2231 to move up and down, and the four guide rods can extend and retract along the slider 215 during the lifting and lowering of the push plate 2231; the connecting plate 2232 is located below the push plate 2231 and is connected to the push plate 2231 as a whole through the S-shaped connecting block 2235; the vertical plate 2233 is vertically screwed to the bottom surface of the connecting plate 2232, and the two sides of the vertical plate 2233 are provided with reinforcing plates 2236 between the vertical plate 2233 and the connecting plate 2232. The upper part of the bellows cover 2234 is fixed to the bottom surface of the slider 215, and the lower part can be fixed to the reinforcing plate or the vertical plate, and the two sides of the connecting plate 2232 are also connected to the inner wall of the bellows cover 2234. The bellows cover 2234 can cover the piston rod end of the servo cylinder, the push plate, the connecting plate and other components, thereby effectively preventing dust, dirt and debris from entering the moving parts of the lifting mechanism. The bottom of the vertical plate 2233 is hinged to the gripping component.

[0056] The working principle of the lifting mechanism in this embodiment is as follows: the piston rod of the servo electric cylinder 221 extends and drives the push plate 2231 to descend, and the push plate 2231 drives the connecting plate 2232 and the vertical plate 2233 to descend as a whole. At the same time, the bellows cover 2234 will also extend and retract, thereby driving the gripping component to descend.

[0057] The gripping assembly includes two wing plates 231, cylinders 232 for controlling the rotation of the wing plates, and suction cups 233 located on the bottom surface of the wing plates. A rotating shaft 2237 is connected to the bottom of the vertical plate 2233, and the rotating shaft 2237 can be connected to the vertical plate 2233 via a connecting assembly. Both wing plates 231 are fitted onto the rotating shaft 2237 and can rotate along the shaft. There are two cylinders 232; the cylinder bodies of the two cylinders are connected to the bottom surface of the connecting plate 2232, and the piston rods are hinged to the corresponding wing plates 231. The rotation of the wing plates 231 is achieved by extending and retracting the piston rods. Initially, both wing plates 231 are in a horizontal position.

[0058] The workflow of this embodiment includes the following steps:

[0059] S201: After the packaging bag is transported to the gripping position of the packaging bag conveying platform 3, the moving slide 211 drives the lifting mechanism together with the gripping component to move above the gripping position of the packaging bag. Then, the servo cylinder 221 controls the second lifting frame 223 to drive the two horizontally set wing plates 231 to press down onto the surface of the packaging bag. The suction cups 233 on the bottom of the wing plates adsorb the packaging bag. After being lifted to a certain height, it moves to the next work station.

[0060] S202: The packaging bag moves from one side of the collecting hopper 4 to the other side with the moving slide 211. During the movement, the bottom of the packaging bag is cut open by the bag-breaking knife 6, completing the unloading. The material is output from the collecting hopper 4.

[0061] S203: While the packaging bag is being fed, the wing plate 231 is controlled by the cylinder 232 to rotate and adsorb the packaging bag. Then, driven by the cylinder 232, the packaging bag adsorbed on the suction cup 233 is repeatedly shaken to shake off the material remaining in the packaging bag.

[0062] S204: After the material is unloaded, the moving slide 211 moves the waste bag to the top of the transport trolley 8. The suction cup 233 releases the pressure, and the waste bag automatically falls into the transport trolley 8. The wing plate 231 retracts, and the servo cylinder 221 controls the second lifting frame 223 to drive the wing plate 231 to press down or repeatedly push the waste bag that has fallen into the transport trolley 8 to ensure that the waste bag in the transport trolley 8 does not overflow. After the packaging bag in the transport trolley 8 is full, the transport trolley 8 is pushed out by manpower to the target position to unload the bag.

[0063] Furthermore, the term "connection" should be interpreted broadly, for example, it can include fixed connections, detachable connections, or integral connections; it can include direct connections or indirect connections through an intermediate medium, and it can also include internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0064] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0065] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application.
