Description

Technical Field

[0001] The present invention relates to the field of automation, in particular to a lancing pen packaging machine. Background Art

[0002] A lancing pen is a pen-shaped blood collection device that is used in conjunction with a disposable sterile lancet. It is a manual ejection-type auxiliary blood collection device for collecting peripheral blood samples from the human body. In order to ensure that it does not require disinfection during use, each lancing pen is individually packaged. At the same time, in order to facilitate users to understand how to use it, an instruction manual is also included in each packaging bag, which makes its production and processing somewhat difficult.

[0003] Existing lancing device packaging is semi-automatic, where the unwinding and heat-sealing of the packaging film are automated, while the insertion of the instructions, the loading of the lancing device, and the subsequent cutting are all manual operations.

DETAILED DESCRIPTION

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] like Figure 1 As shown, the present invention provides a lancing pen packaging machine, comprising a cabinet 1, on which an unwinding mechanism 2, a coding mechanism 3, a punching mechanism 4, a V-shaped folding mechanism 5, a preliminary heat-sealing mechanism 6, an instruction manual loading mechanism 7, a lancing pen loading mechanism 8, a heat-sealing mechanism 9, a traction guide mechanism 10 and a cutting mechanism 11 are sequentially arranged according to the processing flow. The unwinding mechanism unwinds the plastic film in an orderly manner through an unwinding motor and a tensioning assembly. The coding mechanism is located behind the unwinding mechanism and codes the surface of the plastic film. The punching mechanism punches air holes in the plastic film. The V-shaped folding mechanism folds the flat plastic film into a V-shape, and uses the preliminary heat-sealing mechanism to perform vertical heat-sealing to form packaging cavities one by one. Each packaging cavity is transmitted to the instruction manual loading mechanism, and the folded instruction manual is loaded into the packaging cavity by using the downward pressure cylinder. The lancing pen loading mechanism loads the lancing pen into the packaging cavity one by one, and the heat-sealing mechanism performs overall heat-plastic sealing on all sides of the packaging cavity to form a complete package. The traction and guiding mechanism pulls the packaged lancing pen backward and finally cuts it through the cutting mechanism to form independent packages.

[0048] Specifically, the unwinding mechanism is located at one end of the cabinet to realize the unwinding of the plastic film. Its structure is as follows: Figures 2-3As shown, it includes an unwinding mounting frame 201, a material reel 202 fixed on the unwinding mounting frame, rollers fixed at different positions on the unwinding mounting frame, a slide rail 203 vertically fixed on the unwinding mounting frame, and a tensioning roller 204 installed on the slide rail slider. The unwinding mounting frame includes two oppositely arranged vertical frames 205, the vertical frames of which are fixed on the cabinet, and a first roller 206, a second roller 207 and a third roller 208 are provided between the two vertical frames, wherein the first roller is located at the top of the vertical frame and the second roller is located in the middle. The third roller is located at the lower end, and a first horizontal frame 209 is provided at the vertical frame corresponding to the first roller. The material reel is installed on the first horizontal frame, and the end of the material reel passes through the first horizontal frame and is connected to the unwinding motor 2010 on the back. The unwinding motor drives the material reel to rotate, thereby driving the raw material roll mounted on the material reel to rotate and unload. A second horizontal frame 2011 is provided at the vertical frame corresponding to the second roller, and the fourth roller 2012 and the fifth roller 2013 are respectively fixed on the second horizontal frame. The punching mechanism is also fixed on the second horizontal frame The third roller is provided with a third horizontal frame 2014 at the vertical frame corresponding to the third roller, and a sixth roller 2015 is provided on the third horizontal frame. A connecting plate is provided between the second horizontal frame and the third horizontal frame, and a seventh roller 2016 is provided on the connecting plate. With reference to the main view, the seventh roller is located between the fourth roller and the fifth roller, and between the fourth roller and the sixth roller in terms of layout. The slide rail is vertically fixed on the second horizontal frame and the third horizontal frame, and is located between the fifth roller and the sixth roller. The plastic film passes over the second roller and the fourth roller, passes over the top of the fifth roller and goes downward, passes under the tensioning roller, and then continues to pass over the top of the seventh roller and is sent downward to the sixth roller. It is transmitted from under the sixth roller and the third roller through the rear V-shaped folding mechanism. When in use, the tensioning roller slides up and down along the slide rail to ensure that the plastic film is in a straight state. When the material reel is unwinding, the tensioning roller moves down. As the rear processing moves, the tensioning roller gradually moves up. In order to achieve stable unwinding, proximity switches 2017 are respectively provided at the upper and lower ends of the guide rail to detect the moving position of the tensioning roller to control the power on and off of the unwinding motor.

[0049] The coding mechanism is fixed on the cabinet through the lifting frame 12 and is located behind the unwinding mechanism. The raised coding mechanism is at the same height as the second horizontal frame, so that the plastic film can be transported horizontally and coding and punching can be realized synchronously. The specific coding mechanism structure is as follows: Figure 4As shown, it includes a mounting bracket 301, a coding back plate 302, an ink ribbon roll 303, a waste roll 304, a drive motor 305, a vertical guide rail 306, a connecting block 307, a heating block 308, a material receiving roller 309 and a plurality of guide rods 3010. The mounting bracket is L-shaped, and a guide rail 3011 is installed on its upper end. The coding back plate is fixed on the slider of the guide rail and can be adjusted left and right according to the coding position. The ink ribbon roll and the waste roll are mounted on the front of the coding back plate through a rotating shaft. The drive motor is mounted on the back of the coding back plate. The rotating shaft passes through the coding back plate and is equipped with a cam 3012. The vertical guide rail is fixed to the front of the coding back plate and is located below the cam. The connecting block is slidably assembled with the vertical guide rail. At the same time, the connecting block is connected to the connecting rod 3011. 013 is connected to the cam. When the driving motor drives the cam to rotate, the connecting block moves up and down along the vertical guide rail. The heating block is installed on the connecting block, and the corresponding font is embedded below it. The receiving roller is installed on the front of the coding back plate and is located below the waste roll, and the guide rods are installed at different positions on the front of the coding back plate. After the ink ribbon is drawn out from the ink ribbon roll, it is guided to the heating block through multiple guide rods, passes through the bottom of the heating block, passes through the receiving roller and is wound through the waste roll. When the plastic film passes from under the heating block, as the heating block rises and falls, the font presses the ink ribbon and the plastic film, thereby coding on the plastic film. In order to achieve bottom load-bearing, a support plate 3014 is provided under the mounting bracket to support the plastic film from below during coding.

[0050] The punching mechanism structure is as follows Figure 5 As shown, it includes a base 401, a column 402, a punching cylinder 403 and a punch 404. The base is fixed on the second horizontal frame, and a slot 405 is provided on the side for the plastic film to pass through. The surface of the base is provided with a punching hole 406 that passes through the top and bottom and connects to the slot. The column is fixed on the base, and the punching cylinder is installed on the column. The telescopic end of the punching cylinder is fixed with a punch, and the punch is opposite to the punching hole. The plastic film passes through the slot, and the punch moves downward under the control of the punching cylinder to punch out air holes on the surface of the plastic film. The waste plastic film punched out falls down along the punching hole and falls into the waste box 407 located below the punching mechanism.

[0051] The V-shaped folding mechanism is installed in the lifting frame to fold the plastic film sent from the third roller into a V-shape. The specific structure is as follows: Figures 6-7 As shown, it includes a bracket 501, a folding frame 502 and an upper pressure block 503, two shift rods 504 are fixed on the bracket in a V shape, a V-shaped groove is provided on the upper end surface of the folding frame, and the upper pressure block is fixed above the folding frame, and a matching V-shaped protrusion is provided on the lower cross section corresponding to the V-shaped groove. After the two are assembled, a V-shaped feeding trough 505 for the plastic film to pass through is formed. The flat plastic film forms a V-shaped folded state after passing through the V-shaped feeding trough. The bracket is located at the front end of the folding frame and plays the role of support and preliminary folding.

[0052] After the plastic film is folded into a V shape, it needs to be vertically sealed at both ends to form an open packaging cavity. The preliminary heat sealing mechanism realizes the vertical preliminary heat sealing of the plastic film. Its structure is as follows Figure 8 As shown, it includes a heat sealing mounting seat 601, a baffle 602 fixed to one end of the heat sealing mounting seat, a heat sealing cylinder 603 fixed to the other end of the heat sealing mounting seat, and a heat sealing slide rail 604 fixed to the surface of the heat sealing mounting seat. A heat sealing mounting plate 605 is vertically fixed to the slider of the heat sealing slide rail. One side of the mounting plate is connected to the telescopic end of the heat sealing cylinder, and the other side is equipped with a heat sealing block 606. Only then can the plastic film pass through between the heating block and the baffle. The heat sealing cylinder controls the heating block to move along the heat sealing slide rail, and the extrusion force between the heating block and the baffle is used to achieve vertical heat sealing of the plastic film. In actual use, in order to facilitate the subsequent installation of the instruction manual and the lancing pen, only a portion of the plastic film can be heat-sealed in the vertical direction. This allows both the molding of the packaging cavity and the subsequent opening of the packaging cavity. Therefore, a notch 607 is provided on the upper half of the heating surface of the heating block. During heat sealing, only the lower half presses the baffle to achieve heat sealing, and the upper half does not press the baffle. Therefore, during the initial vertical heat sealing, only the lower half of the plastic film is heat-sealed.

[0053] The instruction manual loading mechanism is installed on the cabinet and is located at the rear end of the preliminary heat sealing mechanism. Its structure is as follows: Figure 9 As shown, it includes a loading mount 701, a paper folding machine 702, a double-layer belt unloading assembly 703 and a pneumatic loading assembly 704. The loading mount is fixed on the cabinet, and a drive motor 705 is installed on its side wall. The paper folding machine is fixed on the upper surface of the loading mount. The paper folding machine is a four-folding disk paper folding machine, which is used to fold the blood collection device instruction manual into four folds. A first sprocket 7011 is provided on one side of the paper folding machine, and a second sprocket 7012 is provided on the end of the servo motor. The first sprocket and the second sprocket are connected by a chain (not shown in the figure), so that the paper folding machine is driven by the drive motor 705.

[0054] The pneumatic loading assembly includes a mounting frame 706, a loading cylinder 707 and a loading pressure block 708. The mounting frame is U-shaped, with both ends fixed to the loading mounting seat. The loading cylinder is fixed to the mounting frame. One end of the loading pressure block is connected to the telescopic end of the loading cylinder, and the other end is suspended. The plastic film after the initial heat sealing passes under the loading pressure block. When the packaging cavity is located directly under the loading pressure block, the loading cylinder controls the loading pressure block to press down and load the transferred instruction manual into the packaging cavity. One end of the double-layer belt unloading assembly is located at the discharge port of the paper folding machine, and the other end is located at the loading pressure block. Its structure includes two belt conveyor assemblies arranged side by side, and a gap is formed between the two belt conveyor assemblies for unloading instructions. Each belt conveyor assembly includes an upper belt roller 709, a lower belt roller (not shown) and a belt 7010, wherein the upper belt roller is fixed between the frames on both sides of the paper folding machine discharge port, and the lower belt roller is fixed in the mounting frame. The unloading gap formed between the two upper belt rollers is connected to the paper folding machine discharge port, so that the folded instructions enter between the two belts and are transported downward to the loading block, and the instructions are loaded into the plastic film packaging cavity through the loading block.

[0055] The lancing pen loading mechanism is used to load the lancing pen into the packaging cavity one by one. Its structure is as follows: Figures 10-11 As shown, it includes a hopper 801, an upper pen assembly 802 and a support assembly 803. The hopper is fixed to the cabinet through a second mounting bracket 804. The bottom plate 805 of the hopper is tilted, and a discharge port is provided at the lower end of the bottom plate. The upper pen assembly is installed at the discharge port, including an upper pen wheel 806, a brush 807, a feeding motor 808 and a material stopper 809. The upper pen wheel is fixed to the second mounting bracket with a rotating shaft, and one end of the rotating shaft is equipped with a first synchronous wheel 8010 after passing through the second mounting bracket. Arc-shaped pen grooves 8011 are provided at equal intervals on the circumference of the outer wall of the upper pen wheel. The size of the pen groove is slightly larger than that of a blood collection pen, which can ensure that the blood collection pen falls smoothly into the arc-shaped pen groove. The brush is fixed to the second mounting bracket with a rotating shaft, and one end of the brush is equipped with a second synchronous wheel 8012 after passing through the second mounting bracket. The feeding motor is also fixed on the second mounting bracket, and its telescopic end passes through the second mounting bracket and is respectively connected to the first synchronous wheel and the second synchronous wheel through a synchronous belt, so that the feeding motor drives the upper pen wheel and the brush to rotate, and the brush is located above the upper pen wheel and is arranged tangent to it. Since the brush and the upper pen wheel are located at the discharge port of the inclined material bin, a large number of blood collection pens are accumulated here. As the upper pen wheel rotates, the blood collection pens enter the arc-shaped pen slot, but some blood collection pens are driven to rotate synchronously. The function of the brush is to wipe off the excess blood collection pens to ensure that there is only one blood collection pen in each arc-shaped pen slot. Therefore, the brush and the blood collection pen are set to rotate in opposite directions. The material blocking seat is fixed on the second mounting bracket and is located on the outside of the upper pen wheel. One side of it is provided with an arc surface structure 8013 matching the upper pen wheel, which blocks the blood collection pen from the side to prevent it from falling prematurely.

[0056] The stretching assembly is located just below the upper pen wheel and is used to open the packaging cavity of the plastic film to facilitate the accurate falling of the lancing pen. It includes a stretching base 8014, a first side plate 8015 fixed at one end of the stretching base, and a stretching cylinder 8016 fixed at the other end of the stretching base. The telescopic end of the stretching cylinder is connected to the second side plate 8017. The bottom of the second side plate cooperates with the slide rail to be fixed to the stretching base. The second side plate moves along the slide rail under the drive of the stretching cylinder, and the plastic film passes through between the first side plate and the second side plate. The upper ends of the first side plate and the second side plate are each provided with a plurality of suction cups. When the packaging cavity of the plastic film is delivered, the suction cup of the first side plate sucks one side of the packaging cavity, and the suction cup on the second side plate sucks the other side of the packaging cavity. At the same time, the stretching cylinder retracts to open the packaging cavity opening. At this time, the upper pen wheel rotates, causing the lancing pen in the arc-shaped pen slot to fall into the packaging cavity. After completing the loading of a lancing pen, the suction cup releases the adsorption, and the plastic film continues to be transported.

[0057] After the lancing pen is loaded, it needs to be heat-sealed as a whole. Therefore, a heat-sealing mechanism is provided behind the lancing pen loading mechanism. Its structure is as follows: Figure 12 As shown, it includes a first heat-sealing cylinder 901 and a second heat-sealing cylinder 902 arranged opposite to each other, a plurality of guide pillars 903 connected between the first heat-sealing cylinder and the second heat-sealing cylinder, a first heat-sealing mold 904 fixed to the telescopic end of the first heat-sealing cylinder, and a second heat-sealing mold 905 fixed to the telescopic end of the second heat-sealing cylinder. The first heat-sealing mold and the second heat-sealing mold are both fitted with guide sleeves on the guide pillars and slide back and forth along the guide pillars. Raised heating strips 906 are provided around the opposite surfaces of the first heat-sealing mold and the second heat-sealing mold. The plastic film passes between the first heat-sealing mold and the second heat-sealing mold. When the two are aligned, the raised heating strips around the four sides heat-seal the four sides of the packaging cavity.

[0058] The traction guide mechanism achieves traction of the plastic film through the squeezing force between the two traction wheels. Its structure is as follows: Figure 13As shown, it includes a traction motor 1001, an active traction component connected to the traction motor, and a driven traction component, wherein the traction motor is fixed in the cabinet with a motor base 1002, the active traction component includes an active traction shaft 100, an active traction wheel 1004, and a driving gear 1005. The active traction wheel and the driving gear are mounted on the active traction shaft, and the end of the active traction shaft is connected to the traction motor with a coupling (not shown), especially driving the active traction wheel to rotate. The driven traction component includes a sliding seat 1006 installed on the surface of the cabinet, a mounting plate 100 fixed to the surface of the slider of the sliding seat 7. The driven shaft 1008 is fixed to the mounting plate through the bearing seat. The lower end of the driven shaft is equipped with a driven gear 1009 after passing through the mounting plate. The upper end of the driven shaft is equipped with a rubber-coated wheel 10010. The driven gear and the driving gear are located in the same horizontal plane, and the rubber-coated wheel and the active traction wheel are located in the same horizontal plane. A cam handle 10011 is installed on the side of the mounting plate. By opening and closing the cam handle, the mounting plate moves laterally along the sliding seat, so that the active gear and the driven gear move away from or engage with each other, and the rubber-coated wheel and the active traction wheel are separated and contacted with each other, thereby realizing traction of the plastic film.

[0059] Since the plastic film has a certain thickness after being loaded into the lancing pen, to achieve initial loading, it is necessary to separate the rubber-coated wheel and the active traction wheel to form a certain material feeding gap. After loading, the rubber-coated wheel and the active traction wheel are fitted together, and the extrusion force between them can achieve traction and transfer.

[0060] The cutting mechanism can cut the packaged blood collection devices one by one to form independent units. Its structure is as follows: Figure 14 As shown, it includes a cutting base 1101, a first cutting cylinder 1102 and a second cutting cylinder 1103 relatively installed at both ends of the cutting base, a slide rail installed on the surface of the cutting base between the first cutting cylinder and the second cutting cylinder, a first cutter 1104 installed at the telescopic end of the first cutting cylinder, and a second cutter 115 installed at the telescopic end of the second cutting cylinder. The first cutter and the second cutter are staggered, and the cutting of the passed plastic film is achieved by the telescopic control of the first cutting cylinder and the second cutting cylinder.

[0061] The present invention discloses a lancing pen packaging machine, and its entire working process is as follows: a single-layer plastic film is unwound through a reeling mechanism, the flat plastic film is sequentially coded at a coding mechanism, and air holes are processed at a punching mechanism, and then the flat plastic film is folded into a V-shape through a V-shaped material trough formed by a V-shaped folding mechanism, and then vertically preliminarily heat-sealed by a preliminary heat-sealing mechanism, so that the V-shaped plastic film forms individual packaging cavities, which continue to move forward to the instruction manual loading mechanism for loading the instruction manual, and then the lancing pen is loaded at the lancing pen loading mechanism. After the lancing pen is loaded, the plastic film around the lancing pen is heat-sealed by a fully surrounding heat-sealing mechanism to form a complete packaging structure, which is then cut one by one by a cutting mechanism to form independent individuals.

[0062] This equipment realizes fully automatic packaging of lancing pens, realizes traction and transmission of the entire process through the traction mechanism, and realizes intermittent motion by utilizing the servo characteristics of the traction motor, realizing one transmission and one processing at each processing station, thus making the entire packaging process stable and fast.

[0063] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
