Description

Technical Field

[0001] The utility model belongs to packaging machinery, in particular to a top loading type packaging equipment. Background Art

[0002] Packaging cartons are widely used for packaging of various products, especially for packaging of various medical devices, such as various prefilled needles, syringes, etc. Top loading packaging equipment is used to realize the forming, conveying, loading, sealing and output of packaging cartons, completing the entire process from blank forming to finished box output.

[0003] Existing top loading packaging equipment usually includes a paper blank material warehouse, a paper blank grabbing mechanism, a paper blank boxing mechanism, a carton conveying mechanism, an instruction material warehouse, an instruction box loading mechanism, a material conveying mechanism, a material grabbing mechanism, an inner tongue folding mechanism, a carton sealing mechanism and a carton output mechanism. This packaging equipment has the following problems:

[0004] 1. The paper blank material warehouse is a single-group material warehouse for storage and transportation. When taking out materials, the paper blanks can only be taken out one by one, which affects the speed of taking out and forming. At the same time, the paper blank material warehouse is generally connected to the whole equipment by bolts. It is difficult to replace the fixtures for paper blanks of different specifications, which delays time when changing products and affects work efficiency.

[0005] 2. The paper blank grabbing mechanism is used to grab the packaging box paper blanks in the paper blank material warehouse and place them at a fixed position and angle for subsequent process equipment to use. Most existing grabbing mechanisms use servo motors that rotate forward and reverse through connecting rods to drive the suction fixture to reciprocate, resulting in large equipment vibrations; and when the position sensor fails, the mechanism may swing out of position and hit other mechanism components, causing damage to other mechanism components;

[0006] In addition, the frame of the existing grabbing mechanism is usually formed by bolting and has poor adjustment ability. Moreover, in one packaging device, there are multiple materials to be grabbed at different heights, and the grabbing device requires a specific design and is not very versatile.

[0007] 3. The paper blank boxing mechanism includes a single paper blank gripper mechanism, a glue spraying mechanism and a single-station paper box forming group on the frame. This boxing mechanism can only fold a single paper blank into a box at a time, which has low work efficiency; and the production process may involve frequent changes in packaging materials and paper blank specifications, and the paper blank gripper mechanism needs to be replaced and adjusted, but the existing bolt-on method is not convenient for quick disassembly, which affects production efficiency.

[0008] 4. The inner tongue folding mechanism is used to fold the inner tongues at both ends of the packaging carton horizontally to support and protect the material. The existing folding mechanism uses two symmetrically arranged cylinders to extend and retract at the same time, pushing the pusher to move horizontally to flatten the inner tongue, resulting in large vibration of the equipment, which affects the service life of the equipment.

[0009] 5. The existing carton sealing mechanism realizes the folding and sealing operation of the carton by swinging the swing rod or the swing plate, but this mechanism can only fold and seal the carton one by one, and the work efficiency is low; and the front tongue of the carton cover after sealing is entirely pasted to the front of the packaging box, making it difficult for the end user to open the box and wasting glue.

[0051] The beneficial effects of the utility model are:

[0052] 1. Since the paper blank material store includes a plurality of paper blank conveying mechanisms arranged in parallel, multiple groups of paper blanks can be placed and conveyed at the same time; through the paper blank grabbing mechanism arranged between the paper blank material store and the paper blank boxing mechanism, multiple paper blanks can be grabbed at the same time and sent to the paper blank boxing mechanism;

[0053] 2. Since the paper blank box-forming mechanism includes a paper blank gripper mechanism, a glue spraying mechanism and a paper box forming mechanism; a plurality of cardboard grippers are evenly installed at the lower end of the Z-axis slide of the two-axis linear slide of the paper blank gripper mechanism through a mounting frame, so that paper blanks of multiple packaging cartons can be grasped at the same time and sent to the glue spraying mechanism and the paper box forming mechanism in sequence; since the glue spraying mechanism includes a plurality of pairs of first glue spraying guns evenly arranged in a row and each pair of first glue spraying guns respectively corresponds to the inner tongues at both ends of the paper blanks to be formed; therefore, glue can be sprayed on the inner tongues at both ends of multiple paper blanks at the same time; and multiple forming components evenly distributed on the paper box forming mechanism are used to realize synchronous forming of multiple paper blanks, and automatic box-forming operations of multiple packaging cartons can be realized at the same time, which has high working efficiency and can improve production speed;

[0054] 3. Since multiple cardboard grippers are installed on the two-axis linear slide through mounting brackets and quick-release components, the cardboard grippers can be quickly replaced according to the specifications of the packaging box paper blanks to be replaced. The disassembly and assembly are convenient, which can improve the operating efficiency when replacing different specifications;

[0055] 4. Since the paper blank box forming mechanism, the material grabbing mechanism, the carton sealing mechanism and the carton output mechanism are connected in sequence through the carton conveying mechanism to realize linkage, the material grabbing mechanism can simultaneously grab a pair of materials and put them into the formed carton, and the carton sealing mechanism can simultaneously fold and seal the upper covers of multiple packaging carton boxes; therefore, the forming, loading and sealing of multiple paper blanks can be realized at the same time, and the production efficiency is high.

[0056] 5. Since the paper blank grabbing mechanism drives the driving shaft to rotate continuously through the servo motor, the crank connecting rod assembly at both ends of the driving shaft can drive the two swing arm assemblies hinged on the frame assembly to swing back and forth, thereby driving the suction clamp arranged between the two swing arm assemblies to swing back and forth; by connecting the lower ends of the output arms and the lower parts of the swing arms of the two swing arm assemblies symmetrically in the frame assembly, the output arms can be controlled to rotate back and forth while following the reciprocating swing of the swing arms, thereby adjusting the angle of the suction clamp when following the swing of the swing arm assembly, thereby realizing the grabbing and placing of the paper blank material; the structure is compact, the operation is stable, and the working vibration is small, which can prevent the mechanism from swinging out of position and hitting other mechanism components, causing damage to other mechanism components.

[0057] 6. The two swing arm assemblies symmetrically hinged at one end of the frame group are connected to the mounting plate, and the suction fixture is fixed to the mounting plate by a thumb-type locker. The suction fixture can be quickly replaced according to different specifications, with convenient disassembly and assembly, high replacement efficiency and strong versatility.

[0058] 7. Since the inner tongue folding mechanism adopts a servo motor to connect with the sliding plate through a crank slider mechanism, it can drive the sliding plate to slide back and forth intermittently along the width direction of the mounting base plate, thereby driving the F-type pushers evenly fixed on the two connecting plates to extend and insert into the two ends of each packaging paper box; the two connecting plates are driven by the driving cylinder to slide toward or in the opposite direction, and the two adjacent F-type pushers are symmetrically arranged and respectively fixed on the two connecting plates. Therefore, under the drive of the connecting plate, the two adjacent F-type pushers can move toward each other to realize the automatic folding of the inner tongues of multiple packaging paper boxes, with high working efficiency and smooth movement.

[0059] 8. Since a plurality of sealing clamps are evenly distributed on the mounting frame of the paper box sealing mechanism, the two suction cups symmetrically arranged at the front end of the base plate of each sealing clamp can suck the surface of the box body on one side of the upper cover of the paper box; the folding cylinder arranged between the base plate and the folding plate can drive the folding plate to flip and realize the folding of the upper cover of the paper box; the tongue-pressing cylinder symmetrically arranged on the front end vertical plate at the bottom of the folding plate can paste the glued front tongue of the upper cover on the other side of the box body, so that the automatic folding and sealing of the upper covers of multiple packaging paper boxes can be realized at the same time, and the work efficiency is high; at the same time, the tongue-pressing cylinder can realize accurate pressing of the glue coating point of the front tongue of the upper cover, which can avoid the entire front tongue of the upper cover of the paper box sticking to the front of the packaging box, which causes the problem of difficulty in opening the box for the end user.

The servo motor 529, the drive shaft 503, the swing arm assembly and the control assembly are all arranged on the outer frame. The inner frame is formed by two symmetrically arranged L-shaped connecting seats 517 connected by two symmetrically arranged connecting shafts 518. The outer frame is formed by two vertical plates 519 connected by four connecting shafts 520. The two vertical plates 519 of the outer frame are respectively attached to the two sides of the inner frame and are fixed to the connecting seat 517 of the inner frame through two groups of guide strips 515 and clamping plates 516 symmetrically fixed on the outer side of the inner frame.

Square holes are respectively provided on the two vertical plates 519 corresponding to the two ends of the adjusting shaft 531, and pressure blocks 513 are respectively fixed on the upper ends of the square holes. The pressure blocks 513 are respectively pressed on the outer edges of the corresponding cams 514. A hand wheel 530 is fixed in the middle of the adjusting shaft so that the adjusting shaft 531 can be rotated to adjust the height of the outer frame through the cam, thereby adjusting the grabbing height.

[0135] When working, the initial state is as follows Fig.14 As shown. The control servo motor 529 is started to drive the driving shaft 503 to rotate at a low speed. When the driving shaft 503 rotates, the two swing arm assemblies are driven to swing back and forth through the crank connecting rod assemblies at both ends, thereby driving the suction fixture 509 to swing back and forth; when the two swing arms 507 swing backward, the short connecting rods 512 of the two control assemblies push the small swing arm 502 to swing backward, and at the same time, the lower ends of the output arms 508 of the two swing arm assemblies are driven to rise through the long connecting rod 510, so that the output arms 508 of the two swing arm assemblies are rotated to a horizontal state; thereby adjusting the angle of the suction fixture 509 when following the swing of the swing arm assembly, so that the suction fixture 509 rotates from the initial state to the horizontal state; when the suction fixture 509 is in the initial state, the negative pressure of the suction cup 524 grabs the paper blank material in the paper blank material warehouse 6; when the suction fixture 509 moves to a horizontal state, the paper blank material can be placed in a horizontal state, as shown in FIG. Figure 6 As shown, the paper blanks can be picked up and placed by the subsequent paper blank boxing mechanism.

[0136] When the gripping height needs to be adjusted, the screws of the fixing clamp plate 516 are loosened, and the adjusting shaft 531 is rotated by the hand wheel 530 to drive the cam 514 to rotate so as to adjust the height of the outer frame, thereby adjusting the gripping height. After adjustment, the upper clamp plate 516 is tightened.

The forming components include a guide box component and a press box component.

[0149] The guide box assembly includes two long boxes 202 and two short boxes 203 surrounded by thin plates. The two long boxes 202 are respectively fixed to the front and rear sides of each forming hole 2011 on the mounting plate 201, and the two short boxes 203 are respectively fixed to the left and right ends of each forming hole 2011 on the mounting plate 201. The inner side plates of the long box 202 and the short box 203 are respectively inserted into the forming holes 2011 to achieve guidance when the paperboard of each packaging paper box is inserted into the forming hole 2011.

[0150] The box pressing assembly includes two long side pressing assemblies 204 and two short side pressing assemblies 205.

[0153] During operation, when four paper blanks are simultaneously grasped by the paper blank grasping mechanism 5 and swung to a horizontal state, the paper blanks are located directly below the four paperboard graspers 404, and the controller 17 controls the Z-axis slide of the two-axis linear slide 401 to start moving downward, driving the four paperboard graspers 404 downward until the suction cups 4043 contact the corresponding upper surfaces of the paper blanks, and the negative pressure of the suction cups 4043 sucks the paper blanks;

[0154] Then, the X-axis slide of the two-axis linear slide 401 is controlled to start, driving the four paperboard grippers 404 to carry the adsorbed paper blanks and move forward in the horizontal direction until they pass the photoelectric sensor 305. The photoelectric sensor 305 detects that the paper blanks have passed, and sends a signal to the controller 17. The controller 17 controls the hot melt adhesive device to start, and the first glue gun 307 simultaneously sprays glue on the lower surface of the inner tongue 2003 at both ends of each paper blank.

[0168] The crank slider mechanism includes a circular driving disk 1511 fixedly clamped on the output end of the servo motor 1508. The driving disk 1511 passes through a through hole provided on the mounting base plate 1501 and an eccentrically arranged pin shaft 1513 is inserted on the driving disk 1511. A linkage block 1507 is fixed to the bottom surface of the sliding plate 1503 by screws. A long hole is provided on the linkage block 1507. The upper end of the pin shaft 1513 is inserted into the strip hole through a clearance fit, so that when the pin shaft 1513 rotates with the driving disk 1511, it slides back and forth in the long hole, thereby driving the sliding plate 1503 to slide back and forth intermittently.

[0169] Limiting plates 1502 with internal limiting grooves are fixed to both ends of the sliding plate 1503 by screws, and rubber limiting columns 1514 are fixed to the mounting base plate 1501 at positions corresponding to the limiting plates 1502 . The limiting columns 1514 are inserted into the limiting grooves to achieve sliding limiting of the sliding plate 1503 .

[0170] Two connecting plates 1505 are slidably installed on the sliding plate 1503 through two longitudinal slide rail assemblies 1506. The two connecting plates 1505 are parallel to each other and staggered. A driving cylinder 1510 is fixed on the sliding plate 1503 near both ends through cylinder seat plates. One end of the piston rod of the driving cylinder 1510 is connected to the corresponding connecting plate 1505 through a screw and a nut, so as to drive the two connecting plates 1505 to slide toward or in the opposite directions.

[0171] F-shaped push handles 1509 are evenly fixed on the two connecting plates 1505 by screws, one end of the F-shaped push handles 1509 extends to the same side of the two connecting plates 1505, two adjacent F-shaped push handles 1509 are symmetrically arranged and the other ends are fixed on the two connecting plates 1505, and are used to move the two adjacent F-shaped push handles 1509 towards each other under the drive of the connecting plates 1505 to achieve simultaneous folding of the inner tongues at both ends of multiple packaging paper boxes 20. The F-shaped push handle 1509 is composed of a connecting rod and a U-shaped folding piece fixed at one end of the connecting rod, and the outer end of the U-shaped folding piece is turned up to protect the inner tongues at both ends of the packaging paper box when folding.

[0172] A protective cover 1512 is fixed to the mounting base plate 1501 by four columns and screws. The protective cover 1512 covers the sliding plate 1503, the transverse slide rail assembly, the connecting plate 1505, the longitudinal slide rail assembly and the driving cylinder 1510. The F-shaped push handle 1509 extends out from an opening on one side of the protective cover 1512.

[0173] When working, the driving cylinder 1510 is in an extended state in the initial state. The four formed packaging paper boxes 20 are transported to the folding mechanism through the paper box fixing fixture on the magnetic suspension conveyor line and stop. The servo motor 1508 is started by the controller 17. When the pin shaft 1513 on the driving disk 1511 rotates with the driving disk 1511, it slides back and forth in the long hole, which can drive the sliding plate 1503 to slide to one side of the packaging paper box, thereby driving the F-shaped push handle 1509 to be inserted into the two sides of each packaging paper box 20 respectively;

[0174] Then, the two driving cylinders 1510 are controlled to start retracting at the same time, and each adjacent pair of F-shaped pushers 1509 are driven to move toward each other through the two connecting plates 1505, so as to push the inner tongues 2001 at both ends of each packaging paper box 20 to fold inward to a horizontal state. After the inner tongues are folded, the driving cylinders are controlled to extend, and each adjacent pair of F-shaped pushers 1509 are driven to move in the opposite direction and exit the packaging paper box;

[0175] Finally, the servo motor 1508 is controlled to start, and the sliding plate 1503 is driven to reset through the crank slider mechanism, thereby driving the F-shaped pusher 1509 to return to the initial position to prepare for the next action. After the inner tongue is folded, the spider hand robot is controlled by the controller 17 to start, driving the suction cup gripper 142 to simultaneously grab a pair of materials from the two conveyor belt mechanisms and put them into the formed paper box. The suction cup gripper repeats the action once, and the loading of four packaging paper boxes can be completed.

[0176] A pair of second glue guns are provided between the third and fourth structural units on the frame 16. The second glue guns are connected to the hot melt glue device through a rubber hose (not shown in the figure) to glue the front tongue of the upper cover of the formed paper box. During operation, when the loaded packaging paper box is transported to the second glue gun through the paper box fixing fixture on the magnetic suspension conveyor line, the packaging paper box is detected by the photoelectric sensor close to the second glue gun, and a signal is sent to the controller 17, which controls the hot melt glue device to start, and the second glue gun performs two-point glue spraying on the inner side of the upper cover front tongue 2002 of each packaging paper box 20 passing by.

A plurality of sealing fixtures 1303 are evenly distributed on the mounting frame 1304. This embodiment takes four sealing fixtures as an example, which are used to fold and seal the upper covers of four packaging paper boxes at the same time.

The bottom surface of the folding plate 1309 is flush with the outer end surface of the positioning plate 1313 in the initial state.

[0182] During operation, when the loaded packaging carton is transported to the bottom of the four box sealing fixtures 1303 by the carton fixing fixture on the magnetic suspension conveyor line, the controller 17 controls the Z-axis slide of the two-axis linear gantry 1301 to start downward, driving the four box sealing fixtures 1303 downward and respectively attached to the outer side of the box body on the upper cover side of the corresponding carton, and the negative pressure of the suction cup 1311 sucks the box body surface on the upper cover side of the carton;

[0183] Then, the folding cylinder 1308 is controlled to start, and the folding plate 1309 is pushed to flip and fold the upper cover of the paper box until the folding plate 1309 is flipped to a horizontal state. At this time, the upper cover of the paper box is covered on the upper opening of the box body, and the front tongue of the upper cover coated with glue is pressed and folded to the other side surface of the box body by the vertical plate at the front end of the folding plate 1309;

[0184] Then, the tongue-pressing cylinder 1310 is controlled to start, pushing the glue point of the front tongue of the upper cover to stick to the other side surface of the box body to achieve box sealing; finally, the Z-axis slide of the two-axis linear gantry 1301 is controlled to move upward, and the sealed carton is taken out by the carton fixing fixture, and is sent to the next process through the X-axis slide of the two-axis linear gantry 1301.

[0187] A linear guide rail assembly 1802 is fixed along the longitudinal direction of the lower plate of the mounting plate frame 1801, and a sliding plate 1805 is slidably mounted through the linear guide rail assembly 1802. A driving cylinder 1809 is fixed at the bottom of the mounting plate frame 1801 through two L-shaped cylinder brackets. The piston rod output end of the driving cylinder 1809 is fixedly connected to the sliding plate 1805 through a connecting frame 1808, and is used to drive the sliding plate 1805 to slide back and forth. The connecting frame 1808 is inserted into the mounting plate frame 1801 through the strip hole provided on the lower plate and is connected to both sides of the middle part of the sliding plate 1805 through screws;

[0188] A plurality of rotating shafts 1807 are evenly installed on the upper plate of the mounting plate frame 1801 through bearing seats 1806 and bearings, and four rotating shafts are used as an example in this embodiment. The lower end of each rotating shaft 1807 is connected to the sliding plate 1805 through a gear rack assembly, and a suction cup seat 1811 is fixed to the upper end of the rotating shaft 1807 through screws.

[0190] During operation, after four sealed packaging cartons are placed on the carton support plate 1810 respectively by the four sealing clamps 1303 of the carton sealing mechanism 13, the tongue pressing cylinder and the folding cylinder of the sealing clamp are controlled to retract, and after releasing the packaging cartons, they are reset to prepare for sealing the next group of cartons;

[0191] After the box support plate 1810 receives the material packaging box, it is fixed by suction through the suction cup 1812; the driving cylinder 1809 is started, and the driving cylinder 1809 drives the sliding plate 1805 to slide on the linear slide rail assembly 1802 through the connecting frame. When sliding, the gear rack assembly drives multiple rotating shafts 1807 to rotate synchronously, which can drive the suction cup seat 1811 at the upper end of each rotating shaft 1807 and the box support plate 1810 to rotate synchronously, so that the sealed packaging carton is rotated 90 degrees and then supplied to the carton output mechanism.
