Description

Technical Field

[0001] The present invention relates to the technical field of straw packaging, and particularly to a fully automatic straw packaging device. Background Art

[0002] In the pharmaceutical packaging industry, it is often necessary to place utensils for taking medicine, such as straws, in the oral liquid medicine packaging in the same number as the medicine bottles for consumers to use. Currently, two layers of BOPP (biaxially oriented polypropylene) films are used. Under a specific temperature (about 120 - 160 °C), pressure is applied through a heat sealer to melt and bond the two layers of films in the straw interval area. The straws are loaded into the melted independent compartments, and multiple compartments filled with straws are connected into a strip and packaged into a roll. When leaving the factory, it is necessary to cut into rows (or sheets) in any specified quantity according to the requirements of users such as pharmaceutical factories or food factories. Currently, it is mainly cut manually by tearing or using scissors, which is likely to cause quality accidents such as too many or too few straws in each section and the rupture of the straw row. Moreover, the production efficiency is low due to manual cutting, and it also brings a risk of contamination to food-grade or pharmaceutical-grade straws.

[0003] Therefore, on the basis of realizing continuous operation of the equipment, how to automatically cut continuously according to any target value, ensure that the number of straws on the cut straw row is exactly the same as the target value, and accurately wrap and load the straw row into a tubular container to achieve the packaging of straws is a technical problem that urgently needs to be solved at present.

[0055] Now, the present invention will be further described in conjunction with the drawings of the specification.

[0056] An embodiment of the present invention provides a fully automatic straw packaging device, as Figure 1 shown. The fully automatic straw packaging device includes a straw positioning and cutting assembly 100, a feeding assembly 200, an alignment and inspection assembly 300, and a picking assembly 400. Among them, the straw positioning and cutting assembly 100 is used to cut a straw row 600 with a set number of straws from a straw packaging tape 500; the feeding assembly is used to provide a sleeve 700 for packaging the straw row 600; the alignment and inspection assembly 300 is arranged corresponding to the position of 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 assembly 300, wrap the straw row 600 into the sleeve 700.

[0057] In this embodiment, the straw positioning and cutting assembly 100 is used to cut out a straw row 600 containing a set number of straws. The material taking assembly 400 is used to take out the straw row 600 and send it into the sleeve 700 provided by the feeding assembly 200 through the alignment and material inspection assembly 300, so as to realize the packaging of a set number of straws. The whole process can be realized through full automation, thus realizing the efficient, accurate and intelligent production of the straw packaging process, and having significant application value in fields such as food and medical treatment where high hygiene standards and packaging quality are required.

[0058] In a specific embodiment of the present invention, the specific structure of the straw positioning and cutting assembly 100 is provided, as Figure 2 and Figure 3 shown. The straw positioning and cutting assembly 100 includes a straw positioning and cutting gear tooth 101, a roller 102, a tensioning wheel 103 and a mounting plate 104. The straw positioning and cutting gear tooth 101, the roller 102 and the tensioning wheel 103 are all arranged on the mounting plate 104. The roller 102 is used to assemble the straw packaging tape 500. One end of the straw packaging tape 500 is arranged on the straw positioning and cutting gear tooth 101 after passing through the tensioning wheel 103. The straw positioning and cutting gear tooth 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 arranged at the upper end of the tooth body 1011. The tooth body 1011 is provided with a plurality of arc-shaped grooves 1016 and a plurality of cutting grooves 1017. One cutting groove 1017 is arranged between two arc-shaped grooves 1016. The diameter of the cutting groove 1017 is smaller than that 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.

[0059] In this embodiment, the rotation amount control of the tooth body 1011 can be realized by controlling the tooth body power assembly 1012. When the straw packaging tape 500 is placed on the tooth body 1011, the straws on the straw packaging tape 500 will be embedded into the arc-shaped grooves 1016 under the action of the arc-shaped baffle 1013. According to the number of straws required for packaging, the tooth body power assembly 1012 (for example, a servo motor) is controlled to work, so that the tooth body 1011 rotates a certain angle. Subsequently, by controlling the action of the cutting cylinder 1015, the cutter 1014 makes a cutting action in the vertical direction to complete the cutting of the straw packaging tape 500, thereby obtaining a straw row 600 with a set number of straws. Due to the design of a plurality of arc-shaped grooves 1016 and a plurality of cutting grooves 1017, when the cutter 1014 performs the cutting operation, it can ensure that it only cuts the packaging film on the straw packaging tape 500 and does not accidentally touch the straws therein, thereby effectively ensuring the stability and effectiveness of the cutting.

[0060] In some embodiments, a cutter mounting bracket 1018 is disposed on the cutting cylinder 1015 , and the cutter 1014 is mounted on the cutter mounting bracket 1018 .

[0061] In some embodiments, a slot 1019 is disposed on the arc-shaped baffle 1013 , and the cutter 1014 is disposed in the slot 1019 .

[0062] In some embodiments, an elastic component 1020 is disposed in the cutting groove 1017 to ensure that the straw film strip can be easily cut between the elastic component 1020 and the cutter 1014 .

[0063] In a specific embodiment of the present invention, a specific structure of the feeding assembly 200 is provided, such as Figure 4 As shown, the feeding assembly 200 includes a sleeve feed hopper 201, a feed control structure 202, a sleeve conveyor belt 203, a first ejecting cylinder 204 and a sleeve transfer structure 205; wherein, a discharge port 206 is provided at the bottom of the sleeve feed hopper 201, and a feed control structure 202 is provided corresponding to the discharge port 206; the sleeve conveyor belt 203 is provided at the bottom of the sleeve feed hopper 201, and the first ejecting cylinder 204 is provided below the sleeve conveyor belt 203, and is used for conveying the sleeve 700 on the sleeve conveyor belt 203 to the first station; the sleeve transfer structure 205 is used for transferring the sleeve on the first station to the second station.

[0064] In this embodiment, the sleeve feed hopper 201 serves as a storage container for the sleeves, and the sleeves to be used are stacked inside. The discharge port 206 is located at the bottom of the feed hopper, and the natural fall of the sleeves is achieved by gravity. The feed control structure 202 is arranged at the discharge port 206, and the single discharge quantity of the sleeves can be controlled by a mechanical baffle or a solenoid valve to prevent the sleeves from piling up or getting stuck. The sleeve conveyor belt 203 receives the sleeves 700 falling from the discharge port 206, and conveys the sleeves to the designated position at a uniform speed through the sleeve conveyor belt 203. The first ejection cylinder 204 is located below the sleeve conveyor belt 203. When the sleeve reaches the predetermined position, the cylinder is lifted upward to transfer the sleeve from the sleeve conveyor belt 203 to the first position (the taking position of the sleeve transfer structure 205), completing the preliminary positioning of the sleeve. The sleeve transfer structure 205 can use a mechanical clamp, a vacuum suction cup or a push rod mechanism to grab the sleeve on the first station and transfer it to the second station (such as the assembly position of the straw row) through a linear module or a rotating arm to ensure that the sleeve is accurately aligned with the straw row.

[0065] In some embodiments, Figure 4 and Figure 5As shown, the feeding control structure 202 includes a power unit 2021, a material sensor 2022, a rotating wheel body 2023, and a controller 2024. The material sensor 2022 is arranged corresponding to the position of the sleeve conveyor belt 203 for detecting the material signal on the sleeve conveyor belt 203. The rotating wheel body 2023 is arranged corresponding to the position of the discharge port. The power unit 2021 is connected to the rotating wheel body 2023. At least two grooves 2025 are provided on the rotating wheel body 2023, and the diameter of the grooves 2025 can accommodate at least one sleeve. The controller 2024 is in signal connection with both the material sensor 2022 and the power unit 2021, and is used to control the power unit 2021 to act according to the material signal to supplement sleeves onto the sleeve conveyor belt 203.

[0066] The feeding control structure 202 realizes precise quantitative feeding of sleeves through a closed-loop control of sensor feedback and mechanical linkage. Among them, the material sensor 2022 continuously detects the material state on the sleeve conveyor belt 203 (such as the absence, accumulation, or insufficient quantity of sleeves), and transmits the signal to the controller 2024. After receiving the sensor signal, the controller 2024 decides whether to trigger the replenishment action through logical judgment (such as setting a "minimum material threshold"). After receiving the controller's instruction, the power unit 2021 drives the rotating wheel body 2023 to rotate. The grooves 2025 (at least two) evenly distributed on the surface of the rotating wheel body 2023 are aligned with the discharge port 206 in sequence during the rotation process. The size of each groove can be designed to only accommodate a single sleeve to ensure the quantification of each material taking. When the groove 2025 passes through the discharge port, the sleeve falls into the groove due to gravity and is taken away from the discharge port area as the rotating wheel body 2023 rotates. The material sensor 2022 can continuously monitor the number of sleeves on the sleeve conveyor belt 203. If it is still lower than the set value, the controller triggers the power unit to replenish materials again until the required quantity is reached.

[0067] In some embodiments, a baffle 207 is provided on the sleeve conveyor belt 203, and the bottom of the sleeve conveyor belt 203 is the first station. The first ejector cylinder 204 is arranged corresponding to the position of the baffle 207.

[0068] In this embodiment, the baffle 207 is used to block the sleeves on the sleeve conveyor belt 203. The sleeve conveyor belt 203 is arranged in an inclined manner. The function of the baffle 207 is to separate the first station on the sleeve conveyor belt 203, so that the first ejector cylinder 204 can jack up the sleeve obliquely upward, and then the sleeve falls into the first station under the action of gravity, facilitating the sleeve transfer structure 205 to transfer the sleeve in the first station to the second station (packaging station).

[0069] In some embodiments, such as Figure 4As 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 installed on the linear motor 2051, and the telescopic end of the first telescopic cylinder 2052 is fixedly installed with the pneumatic gripper 2053.

[0070] In this embodiment, the sleeve transfer structure 205 realizes the efficient and precise transfer of the sleeve from the first station to the second station through the combined motion design of a linear motor + a telescopic cylinder + a pneumatic gripper. The specific process is as follows:

[0071] The linear motor 2051 moves horizontally along the guide rail according to a preset program, driving the first telescopic cylinder 2052 and the pneumatic gripper 2053 to reach directly above the first station (the sleeve positioning point). The linear motor adopts closed-loop control (such as encoder feedback) to ensure that the horizontal movement positioning error ≤ 0.1 mm. After the first telescopic cylinder 2052 receives the grasping signal, the cylinder piston rod extends downward, causing the pneumatic gripper 2053 to vertically descend to the surface of the sleeve. After the pneumatic gripper 2053 contacts the sleeve, the gripper is driven to close by air pressure, clamping the outer wall or inner wall of the sleeve (depending on the gripper design) to complete the grasping action. The piston rod of the first telescopic cylinder 2052 retracts, lifting the clamped sleeve to a safe height to avoid interference with the conveyor belt or other components. The linear motor 2051 drives the entire assembly to move horizontally to the second station (such as the straw row assembly position).

[0072] In a specific embodiment of the present invention, as Figure 6 shown, the fully automatic straw packaging device further includes a blanking chute 800. The alignment and inspection component 300 includes a second ejector cylinder 301, a flipping and fixing structure 302, and an auxiliary coiling structure 303. The output end of the second ejector cylinder 301 is connected to an ejector plate 304 (the second station), and the ejector plate 304 is arranged corresponding to the feeding port position of the blanking chute 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. A clamping groove is provided on the flipping plate 3022, and the flipping plate 302 is used to fix the sleeve on the ejector plate 304 through the clamping groove. The auxiliary coiling structure 303 includes an auxiliary coiling cylinder 3031 and a coiling groove 3032. The coiling cylinder 3031 is connected to the coiling groove 3032. The alignment and inspection component 300 is used to cooperate with the straw row 600 picked up by the picking component 400 and package it in the sleeve 700.

[0073] In this embodiment, the alignment and inspection component 300 realizes the precise alignment, fixation, and packaging of the straw row and the sleeve through the coordinated actions of multiple groups of cylinders and mechanical jigs. The specific process is as follows:

[0074] The sleeve is positioned and fixed, and the second ejection cylinder 301 is activated: when the sleeve 700 is transferred to the ejection plate 304 (second station), the second ejection cylinder 301 is lifted upward, driving the ejection plate to lift the sleeve to a set height so that its axis is aligned with the feed port of the feed chute 800.

[0075] The flipping fixing structure 302 intervenes, 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 clamping groove, and stably fixes the sleeve on the ejection plate 304.

[0076] Flip angle control: The flip plate 3022 can be rotated to a certain angle (such as 90°) as needed to make the opening direction of the sleeve consistent with the delivery path of the straw row 600.

[0077] The straw row is aligned and guided, and the material taking component 400 transfers the straw row: the material taking component transfers the cut straw row to a position flush with the open end of the sleeve, and the straw row and the sleeve are in a state to be assembled.

[0078] The auxiliary coiling structure 303 assists in positioning, and the coiling cylinder 3031 pushes the coiling slot 3032, so that the straw row 600 taken by the material picking component 400 is placed in the coiling slot 3032. Through the limiting of the coiling slot 3032 and the self-rotation of the material picking component 400, the straw row 600 is rolled into a cylindrical shape (at this time, the diameter of the straw row 600 is smaller than the inner diameter of the sleeve 700).

[0079] The straw row is pushed. Under the guidance of the coil groove 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.

[0080] The flip plate releases the sleeve, the flip cylinder 3021 is reset, the slot releases the sleeve, the ejector plate 304 moves down, the second ejector cylinder 301 retracts, and the ejector plate 304 carries the packaged sleeve down to the feed port position of the feed chute 800.

[0081] The finished product slides into the feeding chute, and the sleeve carrying the straw row 600 slides into the feeding chute 800 by gravity or the auxiliary push rod, and enters the subsequent collection or sealing process. The components are reset, and the turning plate and the coiling chute are returned to the initial position, waiting for the next cycle.

[0082] In a specific embodiment of the present invention, Figure 7As shown in the figure, the material taking assembly 400 includes a first linear drive 401, a second linear drive 402, a coiling cylinder 403 and a clamping needle 404. Among them, the second linear drive 402 is installed 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 coiling cylinder 403 is installed on the second linear drive 402, and the second linear drive 402 is used to drive the coiling cylinder 403 to move in the y direction. The clamping needle 404 is installed on the coiling cylinder 403.

[0083] In this embodiment, the material taking assembly 400 realizes the precise grasping, transfer and release of the straw row through the composite motion design of a double linear drive shaft + pneumatic clamping needle. Its working process is divided into the following stages:

[0084] The first stage is the initialization positioning of the moving axis.

[0085] The first linear drive 401 (X-axis) drives the entire material taking assembly 400 to move horizontally (X direction) along the equipment to the position of the straw positioning and cutting assembly 100.

[0086] The second linear drive 402 (Y-axis) fine-tunes the position along the longitudinal direction (Y direction) of the equipment after the first linear drive completes the X-axis positioning, so that the clamping needle 404 accurately aligns with the grasping point of the straw row (the end of the film in this embodiment).

[0087] Exemplarily, both the first linear drive 401 and the second linear drive 402 adopt a servo motor + ball screw or synchronous belt drive, and cooperate with the encoder feedback to achieve an X / Y axis positioning error ≤ 0.1 mm.

[0088] The second stage is that the clamping needle 404 grasps the straw row.

[0089] Exemplarily, the front end of the clamping needle 404 is designed as a claw structure with an elastic gasket, which closes under the air cylinder pressure to clamp the straw row (to avoid puncturing or slipping). The clamping needle 404 can be internally provided with a pressure sensor to detect the clamping force. If the set threshold is not reached (such as the film is not clamped tightly), the system triggers an alarm and retries the grasping.

[0090] The third stage is to transfer the straw row to the sleeve station.

[0091] X / Y axis synchronous interpolation motion: The first and second linear drives are linked according to a preset path, and the clamped straw row is translated from the cutting station so that it is flush with the second station (sleeve fixing point) of the alignment and inspection component 300.

[0092] The fourth stage is to complete the packaging in cooperation with the alignment and inspection component 300.

[0093] When the material taking component 400 carries the straw row 600 to the opening end of the sleeve, the position is finely adjusted through the vision system or photoelectric sensor so that the axis of the straw row 600 is aligned with the axis of the sleeve 700.

[0094] The coiling groove 3032 of the alignment and material inspection component extends out. At this time, the clamping needle 404 is just located in the coiling groove 3032. The coiling cylinder 403 is controlled to work to guide the straw row to be smoothly inserted into the sleeve after coiling. Subsequently, the clamping needle 404 opens to release the straw row. At the same time, the straw row is further pushed to a set depth in the sleeve by the second linear driving member 402.

[0095] In the fifth stage, reset and cycle preparation. The X / Y axes return to the initial positions: after the release is completed, the first and second linear driving members quickly return to the origin and wait for the next cycle instruction.

[0096] In a specific embodiment of the present invention, as Figure 1 shown, the full-automatic straw packaging device further includes a workbench 900, and the straw positioning and cutting component 100, the feeding component 200, the alignment and material inspection component 300, and the material taking component 400 are all arranged on the workbench 900.

[0097] In this embodiment, taking the workbench 900 as the basic platform of the device, the four core components of the straw positioning and cutting component 100, the feeding component 200, the alignment and material inspection component 300, and the material taking component 400 are integrated on the same plane to ensure the accurate physical position matching of each component and reduce the assembly error caused by independent installation. Through the unified reference plane layout, the continuous assembly line operation of straw row cutting → sleeve feeding → alignment and assembly → finished product blanking is realized, shortening the material transmission distance and improving the production beat.

[0098] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
