Description

Technical Field

[0001] This application belongs to the field of unpacking machine technology, specifically relating to a pre-filled fully automatic unpacking machine. Background Technology

[0002] A depackaging machine is an industrial piece of equipment used to automatically remove the outer packaging of materials. It is mainly used in industries such as pharmaceuticals, food, fine chemicals, and logistics warehousing. Raw materials need to have their outer packaging removed before entering high-cleanliness production processes. To avoid contaminating products in low-cleanliness environments, the industry generally deploys depackaging equipment in relatively low-cleanliness rooms.

[0003] To simplify the unloading process, current mainstream unpacking equipment typically cuts open the outer bags of raw materials beforehand. This exposes the unprotected products inside directly to a low-cleanliness environment, making it easy for airborne dust and microorganisms to adhere to the product surface, significantly increasing the risk of initial contamination. Due to workshop layout limitations, the transport distance between the unpacking equipment and the next process equipment is relatively long. During the transport of products in the low-cleanliness area, dust particles generated from opening the bags will spread with the airflow. Furthermore, the necessary airflow exchange channels between high-cleanliness rooms and low-cleanliness areas significantly increase the probability that these dust particles will penetrate into the high-cleanliness area via airflow. This could not only damage the high-cleanliness environment but also cause secondary contamination in subsequent product processing, resulting in economic losses. Utility Model Content

[0004] This application provides a pre-filled fully automatic unpacking machine, which aims to solve the technical problem in the prior art that raw materials are easily contaminated due to pre-opening before the unpacking machine, and dust easily contaminates the room during transportation.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A pre-filled, fully automatic unpacking machine is provided, comprising: The workbench has a conveyor belt on top that extends along a first path for transporting materials in packaged bags. A cutting assembly is disposed on the first side of the conveyor belt, the cutting assembly having a cutting blade, the cutting blade cutting open the packaging bag of the material on the first side of the conveyor belt; A gripping assembly, located at the end of the conveyor belt, includes a gripping part capable of gripping materials and packaging bags. An ejection assembly is located on the second side of the conveyor belt. The ejection assembly has an ejection end that moves along a second path perpendicular to the first path. The ejection end can abut against the packaging bag and eject the material inside the packaging bag from the first side of the conveyor belt.

[0006] In one possible implementation, the conveyor belt specifically includes a first conveyor belt and a second conveyor belt, which are arranged at intervals along the first path. The first conveyor belt is used to buffer materials, and the second conveyor belt drives the materials to cut the packaging bags.

[0007] In one possible implementation, there are two second transmission belts, and the two second transmission belts are spaced apart along the second path; Guide rails are provided on the outer sides of the two second conveyor belts, and the guide rails are located on the workbench.

[0008] In one possible implementation, the cutting component further includes: The first lifting drive component has its bottom end connected to the worktable, and its top end has a lifting and lowering first lifting end. A cover is provided at the lifting end; A translation drive member is disposed at the top of the inner cavity of the housing, the translation drive member having a telescopic end that extends and retracts along the first path; and The second lifting drive component has its top end connected to the telescopic end, and its bottom end forms a second lifting end that moves up and down. The cutting blade is installed on the second lifting end.

[0009] In one possible implementation, the pre-filled fully automatic unpacking machine further includes a clamping assembly, which comprises: The third lifting drive is erected on the workbench and located on the first side of the conveyor belt. The top of the third lifting drive has a third lifting end that can move up and down. The mounting shaft is rotatably sleeved on the top outer periphery of the third lifting end; and A clamping rod is connected to the mounting shaft, and the clamping rod is adjustable so that its axis is parallel to the first path.

[0010] In one possible implementation, the pre-filled fully automatic unpacking machine further includes a recycling component, which includes a pressing unit and a recycling unit. The pressing unit is located on the workbench and has a vertically movable pressure plate located above the second conveyor belt. The recycling unit has a receiving box with an open top and is located below the second conveyor belt, aligned vertically with the pressure plate.

[0011] In one possible implementation, the pressure-down unit structure further includes: A fourth lifting drive component is erected on the second side of the conveyor belt, the fourth lifting drive component having a fourth lifting end that extends and retracts in the vertical direction; and An adjusting shaft is rotatably sleeved on the fourth lifting end. An adjusting rod extending radially along the outer periphery of the adjusting shaft is connected to the adjusting shaft. The pressure plate is connected to the free end of the adjusting rod. The pressure plate is vertically arranged, and the bottom surface of the pressure plate has a toothed groove.

[0012] In one possible implementation, the recycling unit further includes: Two roller shafts are spaced apart along the second path to form a storage gap. The rotation axis of the roller shafts is parallel to the first path. The two roller shafts are connected by a drive, and the rotation directions of the two roller shafts are opposite. A drive motor, located inside the worktable, has a rotary output end; and A synchronous belt is simultaneously fitted onto the rotary output end and the roller shaft adjacent to the drive motor to achieve a transmission connection between the drive motor and the roller shaft.

[0013] In one possible implementation, the crawling component includes: A support frame is straddling the conveyor belt, and the top of the support frame has a sliding block that moves along the second path; A mounting plate, connected to the sliding block, wherein the surface of the mounting plate is perpendicular to the vertical direction; and Multiple vacuum suction cups are respectively disposed on the bottom surface of the mounting plate, and the vacuum suction cups are used to adsorb materials.

[0014] In one possible implementation, the launch component includes: A mounting frame is straddling the conveyor belt and spaced apart from the gripping assembly along the first path; the top of the mounting frame has a movable block that moves along the second path. A connecting rod, the first end of which is connected to the moving block, and the axis of the connecting rod is parallel to the first path; A mounting rod, the first end of which is connected to the second end of the connecting rod, wherein the axial direction of the mounting rod is parallel to the second path; and An abutment wheel is rotatably mounted on the second end of the mounting rod, with its rotation axis parallel to the first path. The abutment wheel is used to push the material to move.

[0015] The fully automatic pre-filled and sealed outer packaging machine provided in this application, compared with the prior art, places the pre-filled and sealed nested boxes on a conveyor belt, and the material is transported along the first path towards the cutting component. When the material reaches the corresponding station of the cutting component, the cutting blade of the cutting component precisely cuts the packaging bag on the first side of the conveyor belt. The cut material continues to be transported to the end of the conveyor belt, where the gripping component grips the material and packaging bag to achieve positioning and fixation of the material. The ejection end of the ejection component moves along the second path, abuts against the packaging bag, and pushes the material inside the bag from the first side of the conveyor belt to the next process. The fully automated process of transferring the material with the packaged bag to the cutting component for cutting, gripping and fixing it immediately after cutting, and then directionally ejecting the material avoids premature opening and exposure of the material. The positioning of the gripping component and the directional movement of the ejection component shorten the exposure time of the material in the low-cleanliness area after cutting, reducing the risk of dust adhesion. The entire process requires no manual intervention, reducing contamination from human contact and avoiding dust diffusion caused by manual operation, effectively reducing the probability of dust penetrating into the high-cleanliness area and ensuring the cleanliness of subsequent product processing.

[0025] Please refer to the following: Figures 1 to 7 The fully automatic pre-filled packaging unpacking machine provided in this application is described below. The fully automatic pre-filled packaging unpacking machine includes a workbench 1, a cutting assembly 2, a gripping assembly 3, and an ejection assembly 4. The top of the workbench 1 is provided with a conveyor belt 11 extending along a first path, which is used to transport materials with packaged bags. The cutting assembly 2 is located on the first side of the conveyor belt 11 and has a cutting blade 21, which cuts open the packaging bags of the materials on the first side of the conveyor belt 11. The gripping assembly 3 is located at the end of the conveyor belt 11 on the workbench 1 and has a gripping part that can grip the materials and packaging bags. The ejection assembly 4 is located on the second side of the conveyor belt 11 and has an ejection end that moves along a second path, which is perpendicular to the first path. The ejection end can abut against the packaging bag and eject the materials inside the packaging bag from the first side of the conveyor belt 11.

[0026] It should be noted that the first path is the direction of material transportation, and the material is a nest box with a packaging bag. This application integrates cutting and pushing on a workbench 1 to avoid contamination caused by long-distance transportation or premature opening.

[0027] It should be noted that the cutting component 2, the gripping component 3, and the ejecting component 4 are arranged at intervals along the first path on the workbench 1, and are all adjacent to the conveyor belt 11.

[0028] The workflow of this embodiment is as follows: a pre-filled nest box is placed on the conveyor belt 11, and the material is transported along the first path towards the cutting component 2; when the material reaches the corresponding station of the cutting component 2, the cutting blade 21 of the cutting component 2 precisely cuts the packaging bag on the first side of the conveyor belt 11; the cut material continues to be transported to the end of the conveyor belt 11, and the gripping component 3 grips the material and the packaging bag through the gripping part to achieve the positioning and fixing of the material; the pushing end of the pushing component 4 moves along the second path, abuts against the packaging bag, and pushes the material in the bag from the first side of the conveyor belt 11 to the next process.

[0029] The fully automated pre-filled and sealed packaging unpacking machine provided in this embodiment, compared with the prior art, uses a conveyor belt to transfer materials with packaging bags to the cutting component 2 for cutting. After the cutting is complete, the material is immediately gripped and fixed, and then directionally pushed out. This fully automated process avoids premature exposure of the material. The positioning of the gripping component 3 and the directional movement of the pushing component 4 shorten the exposure time of the material in the low-cleanliness area after cutting, reducing the risk of dust adhesion. The entire process requires no manual intervention, reducing contamination caused by human contact and avoiding dust diffusion caused by manual operation. This effectively reduces the probability of dust penetrating into the high-cleanliness area and ensures the cleanliness of subsequent product processing.

[0030] In some embodiments, see Figures 1 to 3 The conveyor belt 11 specifically includes a first conveyor belt 111 and a second conveyor belt 112. The first conveyor belt 111 and the second conveyor belt 112 are arranged at intervals along a first path. The first conveyor belt 111 is used to buffer materials, and the second conveyor belt 112 drives the materials to cut the packaging bags. In this embodiment, the conveyor belt 11 is divided into a first conveyor belt 111 and a second conveyor belt 112, which can avoid the accumulation and congestion of materials at the cutting station, ensure that the materials on the second conveyor belt 112 can be cut stably, and reduce the cutting position deviation or material exposure caused by material accumulation. At the same time, the buffering function can flexibly adapt to the rhythm of the preceding and following processes, improve the overall unpacking efficiency, indirectly shorten the residence time of materials in the low cleanliness area, and further reduce the risk of contamination.

[0031] In some embodiments, see Figures 1 to 3 There are two second conveyor belts 112, and the two second conveyor belts 112 are arranged at intervals along the second path; guide rails 113 are respectively provided on the outer side of the two second conveyor belts 112, and the guide rails 113 are provided on the workbench 1.

[0032] It should be noted that the spacing between the two second conveyor belts 112 is adjustable, which makes it easy to adapt to materials of different sizes and increases its applicability.

[0033] In this embodiment, two spaced second conveyor belts 112 adapt to the shape of the material to ensure stable support. The outer guide rails 113 prevent the material from tilting or shifting during the transmission and cutting process, ensuring that the cutting component 2 can accurately align with the preset position of the packaging bag for cutting, avoiding incomplete bag cutting or premature leakage of material due to tilting. At the same time, it reduces friction between the material and the equipment, reduces the amount of dust generated, and further controls the risk of dust diffusion.

[0034] In some embodiments, the first transmission belt 111 and the second transmission belt 112 have the same structure.

[0035] In some embodiments, see Figure 6 The cutting assembly 2 also includes a first lifting drive 22, a cover 23, a second lifting drive 24, and a translation drive 25. The bottom end of the first lifting drive 22 is connected to the worktable 1, and the top of the first lifting drive 22 forms a first lifting end that can be raised and lowered; the cover 23 is disposed at the lifting end; the translation drive 25 is disposed at the top of the inner cavity of the cover 23, and the translation drive 25 has a telescopic end that can extend and retract along a first path; the top end of the second lifting drive 24 is connected to the telescopic end, and the bottom end of the second lifting drive 24 forms a second lifting end that can be raised and lowered, and the cutting blade 21 is mounted on the second lifting end.

[0036] In practice, the cover 23 descends to protect the cutting blade 21.

[0037] It should be noted that the translation drive component 25 uses a lead screw to drive the second lifting drive component 24 to move along the first path. The translation drive component 25 is equipped with a lead screw and a guide rod. Both the lead screw and the guide rod are rotatably mounted on the top of the cover 23, and the rotation direction is parallel to the first path. The translation drive component 25 is connected to the lead screw at one end. A slider is threaded on the lead screw, and the slider is also slidably engaged with the guide rod, forming a telescopic end.

[0038] In practice, the translation drive component 25 is a rotary motor.

[0039] As another embodiment of the translation drive 25, the translation drive 25 adopts a telescopic cylinder or a servo motor, and the piston end of the translation drive 25 forms a telescopic end.

[0040] In practice, both the first lifting drive component 22 and the second lifting drive component 24 are telescopic cylinders or servo motors.

[0041] The cutting assembly 2 provided in this embodiment can move in a directional manner. The first lifting drive 22 drives the cover 23 to rise and fall as a whole. The second lifting drive 24 and the translation drive 25 work together to control the movement of the cutter. It can be adapted to packaging bags of different heights and specifications, improving the versatility of the equipment. The cover 23 can protect the cutting area, reduce the diffusion of dust generated during bag cutting to the surrounding environment, and reduce the probability of dust penetrating into the high cleanliness area through airflow.

[0042] In some embodiments, see Figures 1 to 3 The pre-filled fully automatic unpacking machine also includes a pressing assembly 5, which includes a third lifting drive 51, a mounting shaft 52, and a pressing rod 53. The third lifting drive 51 is erected on the workbench 1 and located on the first side of the conveyor belt 11. The top of the third lifting drive 51 has a third lifting end that can move up and down. The mounting shaft 52 is rotatably sleeved on the top outer periphery of the third lifting end. The pressing rod 53 is connected to the mounting shaft 52, and the pressing rod 53 can be adjusted so that its axis is parallel to the first path.

[0043] In this embodiment, before the bag is cut, the third lifting drive 51 drives the clamping rod 53 to descend, pressing the edge of the packaging bag to be cut, ensuring that the packaging bag does not deviate when the cutting blade 21 cuts, thus improving the cutting accuracy. The clamping state can also reduce the amount of dust overflowing from the cut when the bag is cut, thus reducing the dust concentration in the low clean area. The rotation design of the mounting shaft 52 can adjust the angle of the clamping rod 53 to adapt to different shapes of packaging bags, further ensuring the clamping effect and indirectly reducing the risk of material exposure.

[0044] In practice, when the material is on the first conveyor belt 111, the clamping rod 53 descends and abuts against the top of the material, which can help buffer the material. When the material is on the second conveyor belt 112, the clamping rod 53 abuts against the top of the cover 23, clamping the cutting edge of the packaging bag of the material, and assisting the cutting blade 21 in cutting the edge of the packaging bag.

[0045] In some embodiments, see Figure 1 , Figure 3 and Figure 7The pre-filled fully automatic unpacking machine also includes a recycling component, which comprises a pressing unit 6 and a recycling unit 7. The pressing unit 6 is located on the workbench 1 and has a vertically movable pressure plate 63, which is positioned above the second conveyor belt 112. The recycling unit 7 has a receiving box 74 with an open top, located below the second conveyor belt 112 and aligned vertically with the pressure plate 63. When the material is pushed out, the pressure plate 63 of the pressing unit 6 can quickly press the empty bag into the receiving box 74 below, preventing the empty bag from remaining on the conveyor belt 11 or drifting with the wind, and reducing the diffusion of dust carried by the empty bag. The receiving box 74 centrally collects the empty bags, facilitating subsequent unified processing, reducing the contact time between the empty bag and the low-cleanliness environment, reducing the pollution of the surrounding environment by dust on the surface of the empty bag, further ensuring the cleanliness of the unpacking area, and reducing the possibility of dust penetrating into the high-cleanliness area.

[0046] In some embodiments, see Figure 1 The pressing unit 6 also includes a fourth lifting drive 61 and an adjusting shaft 62. The fourth lifting drive 61 is erected on the second side of the conveyor belt 11 and has a fourth lifting end that extends and retracts in the vertical direction. The adjusting shaft 62 is rotatably sleeved on the fourth lifting end. An adjusting rod extending radially is connected to the outer periphery of the adjusting shaft 62. A pressure plate 63 is connected to the free end of the adjusting rod. The pressure plate 63 is vertically arranged and has a toothed groove on its bottom surface.

[0047] In this embodiment, the adjusting shaft 62, in conjunction with the adjusting rod, can adjust the angle of the pressure plate 63 to accommodate empty bags with different degrees of wrinkling. The toothed grooves on the bottom surface of the pressure plate 63 can increase the friction with the empty bag, ensuring that the empty bag is reliably pressed into the receiving box 74, preventing the empty bag from getting stuck in the conveyor belt or equipment gaps. The empty bag recycling is more thorough, reducing the dust generated by the residual empty bags, while also reducing the risk of equipment jamming caused by the residue of empty bags, ensuring the continuous and stable process, and indirectly reducing the residence time of materials in low cleanliness areas.

[0048] In some embodiments, see Figure 7 The recycling unit 7 also includes two roller shafts 71, a drive motor 72, and a synchronous belt 73; the two roller shafts 71 are spaced apart along the second path to form a storage gap, the rotation axis of the roller shafts 71 is parallel to the first path, the two roller shafts 71 are connected in transmission, and the rotation directions of the two roller shafts 71 are opposite; the drive motor 72 is located inside the worktable 1 and has a rotation output end; the synchronous belt 73 is simultaneously sleeved on the rotation output end and the roller shaft 71 adjacent to the drive motor 72 to realize the transmission connection between the drive motor 72 and the roller shaft 71.

[0049] In this embodiment, the counter-rotating roller shaft 71 can compress the pressed-in empty bags, reduce the volume of the empty bags, increase the storage capacity of the container 74, and reduce the frequency of empty bag processing; the synchronous belt 73 transmission ensures that the rotation speed of the roller shaft 71 is stable, the empty bag recycling is continuous and uninterrupted, and avoids the accumulation of empty bags and the generation of dust; the dust on the surface of the compressed empty bags is easier to fix, reducing dust shedding during transportation and processing, further controlling the dust concentration in low cleanliness areas, and reducing the risk of contamination to high cleanliness areas.

[0050] In practice, the bottom of the workbench 1 has a receiving channel, and a receiving box 74 is placed in the receiving channel to facilitate the collection of a certain number of packaging bags and their removal.

[0051] In some embodiments, a storage opening is provided on one side of the workbench 1 for storing the edges of the cut packaging bags. The storage opening may or may not be connected to the receiving box 74.

[0052] In some embodiments, see Figure 3 The gripping component 3 includes a support frame 31, a mounting plate 32, and multiple vacuum suction cups 33. The support frame 31 spans the conveyor belt 11, and the top of the support frame 31 has a sliding block 311 that moves along a second path. The mounting plate 32 is connected to the sliding block 311, and the surface of the mounting plate 32 is perpendicular to the vertical direction. The multiple vacuum suction cups 33 are respectively disposed on the bottom surface of the mounting plate 32, and the vacuum suction cups 33 are used to adsorb materials. The multiple vacuum suction cups 33 stably grip materials and packaging bags through adsorption, avoiding material falling or packaging bag damage during gripping. The sliding block 311 can adjust the gripping position by moving along the second path, ensuring that the material is accurately placed at the ejection station, shortening the material transfer time after cutting, and reducing exposure. At the same time, vacuum adsorption avoids mechanical compression and prevents material damage.

[0053] It should be noted that, for reference Figure 4 A rotary motor is connected to the bottom of the support frame 31 (located inside the workbench 1). The rotary motor drives the rotating rod inside the support leg of the support frame 31 to rotate. The two rotating rods rotate synchronously through a synchronous belt. The sliding block 311 is connected to the synchronous belt. When the rotary motor rotates, the synchronous belt can drive the sliding block 311 to move along the second path.

[0054] In some embodiments, see Figure 5The ejector assembly 4 includes a mounting frame 41, a connecting rod 42, a mounting rod 43, and an abutment wheel 44. The mounting frame 41 is straddling the conveyor belt 11 and is spaced apart from the gripping assembly 3 along a first path. The top of the mounting frame 41 has a moving block 411 that moves along a second path. The first end of the connecting rod 42 is connected to the moving block 411, and the axis of the connecting rod 42 is parallel to the first path. The first end of the mounting rod 43 is connected to the second end of the connecting rod 42, and the axis of the mounting rod 43 is parallel to the second path. The abutment wheel 44 is rotatably mounted on the second end of the mounting rod 43, and its rotation axis is parallel to the first path. The abutment wheel 44 is used to push the material to move.

[0055] It should be noted that the movement principle of the moving block 411 is the same as that of the sliding block 311.

[0056] In this embodiment, the abutment wheel 44 moves along the second path to directionally push the material, ensuring that the material is accurately pushed out from the packaging bag cut to the next process, avoiding deviation that could cause the material to collide with the equipment and be damaged or have its exposure time extended; the roller design reduces friction between the abutment wheel 44 and the material, reducing the amount of dust generated by friction, while the pushing process is more stable, preventing the material from shaking and causing residual dust inside the bag to scatter; the cooperation between the moving block 411 and the connecting rod 42 can adapt to materials of different specifications, improving the pushing stability.

[0057] The following is one specific operational step of this application: Materials with outer packaging bags are placed on the first conveyor belt 111 of workbench 1, and the materials are transported along the first path. Guide rails 113 on the outer sides of the two second conveyor belts 112 limit the movement of the materials. The first conveyor belt 111 temporarily stores the materials, and the materials are sequentially transported to the second conveyor belts 112 according to the processing rhythm of the second conveyor belts 112.

[0058] When the material arrives at the cutting station of the second conveyor belt 112, the third lifting drive 51 drives the clamping rod 53 to descend, so that the clamping rod 53 presses the edge of the packaging bag to be cut, ensuring that the packaging bag does not shift during cutting.

[0059] The first lifting drive 22 of the cutting assembly 2 drives the cover 23 to descend, and the cover 23 covers the cutting area to block dust; the second lifting drive 24 drives the translation drive 25 and the cutting blade 21 to descend to the cutting position of the packaging bag; the translation drive 25 drives the cutting blade 21 to move along the conveyor belt 11 to complete the precise cutting of the packaging bag; after the cutting is completed, the cutting blade 21 and the cover 23 are reset in sequence.

[0060] The cut material is conveyed to the end by the second conveyor belt 112. The sliding block on the support frame 31 moves along the second path to adjust the position of the mounting plate 32. Multiple vacuum suction cups 33 descend and adsorb the material and the outer bag that has not completely detached, so as to achieve stable gripping and positioning of the material and prevent deviation.

[0061] The movable block on the mounting frame 41 moves along the second path, causing the connecting rod 42, mounting rod 43 and abutting wheel 44 to approach the material; the abutting wheel 44 pushes the packaging bag along the second path, so that the pre-filled and sealed nest box inside the bag is pushed out from the cutting hole to the next process, while the outer bag is still adsorbed by the gripping component 3.

[0062] After the material is pushed out, the gripping component 3 releases the outer bag, which falls onto the second conveyor belt 112.

[0063] The fourth lifting drive unit 61, activated by the pressing unit 6, drives the adjusting shaft 62, adjusting rod, and pressure plate 63 to descend. The toothed pressure plate 63 contacts the outer bag. The pressure plate 63 presses down on the outer bag, pressing it through the gap of the second conveyor belt 112 into the recycling unit 7 below. The drive motor 72 drives the two roller shafts 71 to rotate in opposite directions through the synchronous belt 73. The outer bag is compressed when it passes through the storage gap formed by the roller shafts 71, reducing its volume.
