[0002] In the pharmaceutical packaging industry, it is often necessary to include a number of medication utensils, such as straws, in oral liquid medicine packaging for consumer use, matching the number of medicine bottles. Currently, two layers of BOPP (biaxially oriented polypropylene) film are used. A heat-sealing head applies pressure at a specific temperature (approximately 120-160℃) to fuse the two layers of film together in the straw-separating area. The straws are then placed into the molten, independent compartments, and multiple straw-containing compartments are connected to form a strip, which is then packaged into a roll. At the factory, the straws need to be cut into rows (or sheets) in batches according to the quantity specified by the pharmaceutical or food factory. Currently, the packaged straws (straw rolls) are manually loaded into sleeves, a method that is inefficient. Therefore, achieving precise alignment, fixation, and packaging of the straw rolls and sleeves is one of the urgent problems that needs to be solved.

[0056] Example 1:
[0057] This utility model embodiment provides an alignment and inspection device for straw packaging, such as... Figure 1As shown, the alignment and inspection device 300 includes a second top-feeding cylinder 301, a flipping and fixing structure 302, and an auxiliary winding structure 303. The output end of the second top-feeding cylinder 301 is connected to a top-feeding plate 304 (second station), which is positioned corresponding to the feed inlet of the feed trough 800. The flipping and fixing structure 302 includes a flipping cylinder 3021 and a flipping plate 3022. The flipping cylinder 3021 is connected to the flipping plate 3022 and is used to drive the flipping plate 3022 to flip. The flipping plate 3022 is provided with a slot, which is used to fix the sleeve to the top-feeding plate 304. The auxiliary winding structure 303 includes an auxiliary winding cylinder 3031 and a winding trough 3032, which is connected to the winding trough 3032. The alignment and inspection device 300 is used to cooperate with the material taking component 400 to pick up the suction tube 600 and package it into the sleeve 700.
[0058] In this embodiment, the alignment and inspection device 300 achieves precise alignment, fixation, and packaging of the straw array and the sleeve through the coordinated action of multiple sets of cylinders and mechanical clamps. The specific process is as follows:
[0059] Sleeve positioning and fixing, second top-loading cylinder 301 operation: After the sleeve 700 is transferred to the top plate 304 (second station), the second top-loading cylinder 301 rises upward, driving the top plate to lift the sleeve to the set height, so that its axis is aligned with the feed port of the discharge trough 800.
[0060] The flipping and fixing structure 302 is engaged, and the flipping cylinder 3021 drives the flipping plate 3022: the flipping plate clamps the outer wall or both ends of the sleeve 700 through the slot, and fixes the sleeve stably on the top plate 304.
[0061] Flip angle control: The flip plate 3022 can be rotated by a certain angle (such as 90°) as needed to make the opening direction of the sleeve consistent with the feeding path of the suction tube 600.
[0062] Straw alignment and guidance, material handling component 400 transfers straws: The material handling component transfers the cut straws to a position flush with the opening end of the sleeve. At this time, the straws and the sleeve are in a state of waiting to be assembled.
[0063] The auxiliary winding structure 303 assists in positioning. The winding cylinder 3031 pushes the winding groove 3032, so that the suction tube 600 picked up by the picking component 400 is placed in the winding groove 3032. Through the limiting of the winding groove 3032 and the rotation of the picking component 400 itself, the suction tube 600 is wound into a cylindrical shape (at this time, the diameter of the suction tube 600 is smaller than the inner diameter of the sleeve 700).
[0064] Guided by the roll trough 3032, the straw row 600 is pushed into the sleeve through the material taking component 400 or the independent push rod mechanism to complete the wrapping.
[0065] The flip plate releases the sleeve, the flip cylinder 3021 resets, the slot releases the sleeve, the top plate 304 moves down, the second top cylinder 301 retracts, and the top plate 304 carrying the packaged sleeve descends to the inlet position of the discharge trough 800.
[0066] The finished product slides into the feeding trough, and the sleeve carrying the suction tube 600 slides into the feeding trough 800 by gravity or an auxiliary push rod, entering the subsequent collection or sealing process. The components are reset, and the flipping plate and the winding trough return to their initial positions, waiting for the next cycle.
[0067] Example 2:
[0068] This utility model embodiment provides a fully automatic straw packaging device, such as... Figure 2 As shown, the fully automatic straw packaging equipment includes a straw positioning and cutting assembly 100, a feeding assembly 200, an alignment and inspection device 300, and a picking assembly 400. The straw positioning and cutting assembly 100 is used to cut a straw row 600 with a set number of straws from the straw packaging belt 500. The feeding assembly is used to provide a sleeve 700 for packaging the straw row 600. The alignment and inspection device 300 is positioned corresponding to the feeding assembly 200. The picking assembly is used to transfer the straw row 600 and, under the alignment action of the alignment and inspection device 300, feed the straw row 600 into the sleeve 700.
[0069] In this embodiment, the straw positioning and cutting component 100 is used to cut out a straw row 600 containing a set number of straws. The material taking component 400 is used to take out the straw row 600 and feed it into the sleeve 700 provided by the feeding component 200 through the alignment and inspection device 300, thereby realizing the packaging of the set number of straws. The whole process can be fully automated, thus realizing efficient, precise and intelligent production of straw packaging process, which has significant application value in fields such as food and medical where hygiene standards and packaging quality requirements are high.
[0070] It should be noted that the specific working principle and effect of the alignment and inspection device 300 have been described in detail in Example 1, so they will not be repeated here.
[0071] In one specific embodiment of this utility model, the straw positioning and cutting assembly 100 is provided with a specific structure, such as... Figure 3 and Figure 4As shown, the straw positioning and cutting assembly 100 includes a straw positioning and cutting wheel tooth 101, a roller 102, a tensioning wheel 103, and a mounting plate 104. The straw positioning and cutting wheel tooth 101, roller 102, and tensioning wheel 103 are all mounted on the mounting plate 104. The roller 102 is used to assemble the straw packaging strip 500. One end of the straw packaging strip 500 is mounted on the straw positioning and cutting wheel tooth 101 after passing through the tensioning wheel 103. The suction tube positioning and cutting wheel 101 includes a tooth body 1011, a tooth body power assembly 1012, an arc-shaped baffle 1013, a cutter 1014, and a cutting cylinder 1015. The arc-shaped baffle 1013 is disposed at the upper end of the tooth body 1011. The tooth body 1011 is provided with multiple arc-shaped grooves 1016 and multiple cutting grooves 1017. A cutting groove 1017 is disposed between two arc-shaped grooves 1016. The diameter of the cutting groove 1017 is smaller than the diameter of the arc-shaped groove 1016. The tooth body power assembly 1012 is connected to the tooth body 1011. The cutting cylinder 1015 is connected to the cutter 1014. The cutter 1014 is located above any one of the cutting grooves 1017.
[0072] In this embodiment, the rotation of the toothed body 1011 can be controlled by controlling the toothed body power assembly 1012. When the straw packaging strip 500 is placed on the toothed body 1011, the straws on the straw packaging strip 500 will be embedded into the arc-shaped groove 1016 under the action of the arc-shaped baffle 1013. According to the required number of straws for packaging, the toothed body power assembly 1012 (e.g., a servo motor) is controlled to work, causing the toothed body 1011 to rotate a certain angle. Then, by controlling the cutting cylinder 1015 to act, the cutter 1014 makes a cutting action in the vertical direction, completing the cutting of the straw packaging strip 500, thereby obtaining a straw row 600 with a set number of straws. Due to the design of multiple arc-shaped grooves 1016 and multiple cutting grooves 1017, the cutter 1014 can ensure that it only cuts the packaging film on the straw packaging strip 500 when performing the cutting operation, without accidentally touching the straws inside, thus effectively ensuring the stability and effectiveness of the cutting.
[0073] In some embodiments, a cutter mounting bracket 1018 is provided on the cutting cylinder 1015, and the cutter 1014 is mounted on the cutter mounting bracket 1018.
[0074] In some embodiments, the arc-shaped baffle 1013 is provided with a slot 1019, and the cutter 1014 is disposed in the slot 1019.
[0075] In some embodiments, an elastic component 1020 is provided in the cutting groove 1017 to ensure that the straw membrane can be easily cut between the elastic component 1020 and the cutter 1014.
[0076] In one specific embodiment of this utility model, the feeding assembly 200 is provided with a specific structure, such as... Figure 4 As shown, the feeding assembly 200 includes a sleeve feed hopper 201, a feeding control structure 202, a sleeve conveyor belt 203, a first top-loading cylinder 204, and a sleeve transfer structure 205. The sleeve feed hopper 201 has a discharge port 206 at its bottom, and the feeding control structure 202 is positioned corresponding to the discharge port 206. The sleeve conveyor belt 203 is located at the bottom of the sleeve feed hopper 201, and the first top-loading cylinder 204 is positioned below the sleeve conveyor belt 203 to transport the sleeves 700 on the sleeve conveyor belt 203 to a first working position. The sleeve transfer structure 205 is used to transfer the sleeves from the first working position to a second working position.
[0077] In this embodiment, the sleeve feed hopper 201 serves as a storage container for sleeves, with sleeves ready for use stacked inside. The discharge port 206 is located at the bottom of the feed hopper, allowing the sleeves to fall naturally under gravity. The feeding control structure 202 is located at the discharge port 206 and can control the number of sleeves discharged at one time via a mechanical baffle or solenoid valve to prevent sleeve accumulation or jamming. The sleeve conveyor belt 203 receives the sleeves 700 falling from the discharge port 206 and transports them at a uniform speed to a designated position. The first lifting cylinder 204 is located below the sleeve conveyor belt 203. When the sleeve reaches the predetermined station, the cylinder lifts upward, transferring the sleeve from the sleeve conveyor belt 203 to the first station (the pick-up position of the sleeve transfer structure 205), completing the initial positioning of the sleeve. The sleeve transfer structure 205 can use mechanical grippers, vacuum suction cups or push rod mechanisms to grab the sleeve on the first station and transfer it to the second station (such as the assembly position of the suction tube row) through a linear module or rotating arm, so as to ensure that the sleeve and the suction tube row are accurately aligned.
[0078] In some embodiments, such as Figure 5 and Figure 6 As shown, the feeding control structure 202 includes a power unit 2021, a material sensor 2022, a rotating wheel 2023, and a controller 2024. The material sensor 2022 is positioned corresponding to the location of the sleeve conveyor belt 203 and is used to detect material signals on the sleeve conveyor belt 203. The rotating wheel 2023 is positioned corresponding to the location of the discharge port. The power unit 2021 is connected to the rotating wheel 2023. The rotating wheel 2023 is provided with at least two grooves 2025, and the diameter of the grooves 2025 is at least able to accommodate one sleeve. The controller 2024 is signal-connected to both the material sensor 2022 and the power unit 2021 and is used to control the operation of the power unit 2021 according to the material signals to replenish sleeves on the sleeve conveyor belt 203.
[0079] The feeding control structure 202 achieves precise quantitative feeding of the sleeves through closed-loop control of sensor feedback and mechanical linkage. The material sensor 2022 detects the material status on the sleeve conveyor belt 203 in real time (such as missing sleeves, accumulation, or insufficient quantity) and transmits the signal to the controller 2024. After receiving the sensor signal, the controller 2024 determines whether to trigger a feeding action through logical judgment (e.g., setting a "minimum material threshold"). Upon receiving the controller command, the power unit 2021 drives the rotating wheel 2023 to rotate. The evenly distributed grooves 2025 (at least two) on the surface of the rotating wheel 2023 align sequentially with the discharge port 206 during rotation. Each groove can be designed to accommodate only a single sleeve, ensuring quantitative feeding each time. When the groove 2025 passes the discharge port, the sleeve falls into the groove due to gravity and is carried away from the discharge port area by the rotating wheel 2023. The material sensor 2022 continuously monitors the number of sleeves on the sleeve conveyor belt 203. If it is still lower than the set value, the controller will trigger the power unit to replenish the material again until the required quantity is reached.
[0080] In some embodiments, a baffle 207 is provided on the sleeve conveyor belt 203, the bottom of the sleeve conveyor belt 203 is the first station, and the first top material cylinder 204 is arranged at the position corresponding to the baffle 207.
[0081] In this embodiment, the baffle 207 is used to block the sleeves on the sleeve conveyor belt 203, wherein the sleeve conveyor belt 203 is arranged at an angle. The function of the baffle 207 is to separate the first station on the sleeve conveyor belt 203 so that the first lifting cylinder 204 can lift the sleeve obliquely upward, and the sleeve falls into the first station under the action of gravity, so that the sleeve transfer structure 205 can transfer the sleeve in the first station to the second station (packaging station).
[0082] In some embodiments, such as Figure 4 As shown, the sleeve transfer structure 205 includes a linear motor 2051, a first telescopic cylinder 2052, and a pneumatic gripper 2053. The first telescopic cylinder 2052 is mounted on the linear motor 2051, and the pneumatic gripper 2053 is fixedly mounted on the telescopic end of the first telescopic cylinder 2052.
[0083] In this embodiment, the sleeve transfer structure 205 achieves efficient and precise transfer of the sleeve from the first station to the second station through a composite motion design of linear motor + telescopic cylinder + pneumatic gripper. The specific process is as follows:
[0084] Linear motor 2051 moves horizontally along the guide rail according to a preset program, driving the first telescopic cylinder 2052 and pneumatic gripper 2053 to directly above the first workstation (sleeve positioning point). The linear motor uses closed-loop control (such as encoder feedback) to ensure that the horizontal movement positioning error is ≤0.1mm. After receiving the gripping signal, the piston rod of the first telescopic cylinder 2052 extends downward, causing the pneumatic gripper 2053 to descend vertically to the sleeve surface. After contacting the sleeve, the pneumatic gripper 2053 closes under air pressure, gripping the outer or inner wall of the sleeve (depending on the gripper design), completing the gripping action. The piston rod of the first telescopic cylinder 2052 retracts, raising the gripped sleeve to a safe height to avoid interference with the conveyor belt or other components. Linear motor 2051 drives the entire assembly to move horizontally to the second workstation (such as the suction tube assembly position).
[0085] In one specific embodiment of this utility model, such as Figure 7 As shown, the material handling assembly 400 includes a first linear drive 401, a second linear drive 402, a coil cylinder 403, and a clamping needle 404; wherein, the second linear drive 402 is mounted on the first linear drive 401, and the first linear drive 401 drives the second linear drive 402 to move in the x direction, the coil cylinder 403 is mounted on the second linear drive 402, and the second linear drive 402 is used to drive the coil cylinder 403 to move in the y direction, and the clamping needle 404 is mounted on the coil cylinder 403.
[0086] In this embodiment, the material handling component 400 achieves precise grasping, transfer, and release of the straw stack through a composite motion design of dual linear drive shafts and pneumatic clamping needles. Its workflow is divided into the following stages:
[0087] The first stage is the initial positioning of the motion axis.
[0088] The first linear drive unit 401 (X-axis) drives the entire material handling assembly 400 to move laterally (X-direction) along the equipment to the position of the suction tube positioning and cutting assembly 100.
[0089] After the first linear drive completes the X-axis positioning, the second linear drive 402 (Y-axis) finely adjusts its position along the longitudinal direction (Y direction) of the device so that the clamp needle 404 is precisely aligned with the gripping point of the suction tube array (the end of the membrane in this embodiment).
[0090] For example, both the first linear drive unit 401 and the second linear drive unit 402 adopt servo motor + ball screw or synchronous belt drive, and with encoder feedback, achieve X / Y axis positioning error ≤0.1mm.
[0091] In the second stage, the 404 pincers grip the straw row.
[0092] For example, the front end of the clamp needle 404 is designed as a gripper structure with elastic padding, which closes under cylinder pressure to clamp the suction tube array (preventing puncture or slippage). The clamp needle 404 can have a built-in pressure sensor to detect the clamping force. If the set threshold is not reached (e.g., the membrane is not clamped), the system triggers an alarm and retryes the gripping.
[0093] In the third stage, the suction tube is transferred to the sleeve station.
[0094] X / Y axis synchronous interpolation motion: The first and second linear drive components move in tandem along a preset path to move the clamped suction tube array from the cutting station so that it is aligned with the second station (sleeve fixing point) of the alignment and inspection device 300.
[0095] In the fourth stage, the packaging is completed in conjunction with the alignment and inspection device 300.
[0096] When the material handling assembly 400 carries the suction tube 600 to the opening end of the sleeve, it finely adjusts the position through a vision system or photoelectric sensor to align the suction tube 600 with the axis of the sleeve 700.
[0097] The material trough 3032 of the alignment and inspection device extends, at which point the clamping needle 404 is positioned within the material trough 3032. The control cylinder 403 operates to guide the suction tube array to be wound and smoothly inserted into the sleeve. Subsequently, the clamping needle 404 opens, releasing the suction tube array. Simultaneously, the suction tube array is further pushed to the set depth within the sleeve by the second linear drive 402.
[0098] Phase 5: Reset and Cycle Preparation. X / Y Axis Returns to Initial Position: After release, the first and second linear drive components quickly return to the origin, awaiting the next cycle command.
[0099] In one specific embodiment of this utility model, such as Figure 2 As shown, the fully automatic straw packaging equipment also includes a worktable 900, a straw positioning and cutting component 100, a feeding component 200, an alignment and inspection device 300, and a picking component 400, all of which are mounted on the worktable 900.
[0100] In this embodiment, the workbench 900 serves as the basic platform of the equipment. The four core components—the straw positioning and cutting assembly 100, the feeding assembly 200, the alignment and inspection device 300, and the picking assembly 400—are integrated onto the same plane, ensuring precise physical matching of each component and reducing assembly errors caused by independent installation. Through a unified reference plane layout, a continuous production line operation is achieved, from straw cutting to sleeve feeding, alignment assembly, and finished product unloading, shortening material transport distances and increasing production cycle time.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
