Description

Technical Field

[0001] The invention relates to the field of workpiece packaging, and in particular to an automatic box packaging device and a paper box taking and opening structure thereof. Background Art

[0002] After the workpiece is processed, it needs to be packaged to facilitate product transportation and later product sales. At present, one of the packaging boxes on the market is Figure 1 As shown, the box body 7 includes a box body 7 and covers arranged at both ends of the box body 7; the covers can be divided into a rear wing 71, a front wing 72 and a box cover 73 as shown in the figure, and the box cover 73 also includes a cover tongue 74 on its end along its fold line. At present, packaging equipment generally requires producers to manually place and package the workpieces and the box body, which not only increases the labor intensity of the producer's processing, but also reduces the packaging efficiency of the workpiece. In addition, conventional packaging machinery is also prone to the defects of stuck parts or unable to quickly package the workpiece, which greatly increases the difficulty of producers in packaging and processing the workpiece. For example, the Chinese invention patent publication with the publication number "CN108945621A" records an automatic workpiece boxing device, which can automatically package the workpieces, effectively reducing the labor intensity of the producer in packaging the workpieces, and improving the convenience and efficiency of the workpiece packaging for the producer; since the frame is provided with a box feeding mechanism, a feeding mechanism, a turntable mechanism, a wing pressing mechanism and a cover closing mechanism, a main motor for driving the turntable mechanism to rotate is provided inside the frame, so that the main motor can drive the disc rack in the turntable mechanism to rotate, and the clamping claws connected to the outside of the disc rack clamp and fix the box body, wherein the box feeding mechanism can transport the box body through the box feeding belt , and at the same time, the box suction cylinder drives the suction rod to grab the box body and place it into the clamp for clamping. The feeding mechanism can clamp the workpiece through the feeding belt, and the discharge cylinder controls the opening and closing of the movable plate to let the workpiece fall into the box body, and then the box wings are folded by the rotating cylinder in the wing pressing mechanism, and the box cover on the box body is closed by the cover closing mechanism, thereby completing the operation process of automatically packaging the workpiece into the box body, changing the labor difficulty and labor intensity required in the conventional workpiece installation process, effectively improving the convenience and efficiency of workpiece packaging for producers, ensuring that producers can continuously and effectively package workpieces, and greatly reducing the labor cost and time cost required for producers to package workpieces.

[0003] However, the technical solution involved in the above-mentioned prior patent application has the following shortcomings, that is, in the technical solution of the prior application text, the packaging box fed by the box feeding mechanism is as shown in its patent Figure 10, not only the entire packaging box is in an open state, but also the cover at one end of the packaging box is already closed, and only the cover at the other end is opened to place the workpiece and automatically seal. However, at present, in order to save transportation space and avoid extrusion damage during transportation, the packaging boxes purchased by upstream suppliers in the industry are all in a flattened state. Therefore, if the technical solution of the above-mentioned prior application text is to be implemented, the flattened box must be folded into the state shown in its patent Figure 10 manually or mechanically in the previous step, so the degree of automation of the above-mentioned technical solution needs to be improved. Summary of the invention

[0004] In order to solve the above problems, the first purpose of the present invention is to provide a carton picking and opening structure, which has the function of automatically feeding a carton in a flat state and opening the carton; compared with the technical solution of the prior patent application recorded in the background technology, this solution fits the current market demand and is a prerequisite for the full-automatic cartoning of a carton in a flat state. The second purpose of the present invention is to provide an automated cartoning device, which has the above-mentioned carton picking and opening structure.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] A carton picking and opening structure comprises a frame, and a carton picking device and a carton opening device arranged on the frame; the characteristic is that the carton picking device comprises a carton grabbing mechanism for receiving a carton at the output end of a carton hopper and moving the carton to a carton opening station, the carton grabbing mechanism comprises an upper suction cup for adsorbing and fixing the upper end surface of the carton; the carton opening device comprises a lower suction cup capable of adsorbing and fixing the lower end surface of the carton and capable of moving forward and downward.

[0007] Preferably, the carton grabbing mechanism comprises a material taking moving pair arranged below the carton hopper, a rotating pair arranged on the material taking moving pair, and an upper suction cup arranged on the rotating end of the rotating pair.

[0008] Preferably, the material picking moving pair includes a longitudinal track arranged on the frame, a longitudinal moving plate arranged on the longitudinal track, and a longitudinal moving cylinder whose output end is connected to the longitudinal moving plate. When the longitudinal moving cylinder is working, it drives the longitudinal moving plate to move up and down along the longitudinal track.

[0009] Preferably, the rotating pair includes a support plate arranged on the longitudinal moving plate, a rotating rod hingedly arranged on the support plate, and a rotating motor or a rotating cylinder whose output shaft is connected to the hinged end of the rotating rod; the rotating motor drives the rotating rod to rotate along its hinge point, and a mounting plate is provided on the rotating end of the rotating rod, and the upper suction cup is arranged on the mounting plate.

[0010] Preferably, the box opening device further comprises a driving assembly, and the lower suction cup is arranged on the working end of the driving assembly. Under the action of the driving assembly, the lower suction cup moves forward and downward.

Since the carton needs to be opened by the coordinated movement of the upper suction cup and the lower suction cup, the lower suction cup needs to be able to move in the downward direction; and because the upper end surface and the lower end surface of the carton in a flat state are staggered, the vertical downward movement can only make the carton present a parallelogram after opening, so the lower suction cup adopts forward and downward movement to align the upper end surface and the lower end surface of the carton after opening, and the carton presents a rectangle after opening. The carton picking and opening structure has the function of automatically feeding a carton in a flat state and opening the carton; compared with the technical solution of the prior patent application recorded in the background technology, this solution is in line with the current market demand and is a prerequisite for fully automatic cartoning of cartons in a flat state.

[0029] Embodiment 1:

[0030] like Figures 2 to 8 An automated box packing device is shown, comprising a frame 1, and a carton picking device, a box opening device, a box loading device, a box loading conveying device and a sealing device which are sequentially arranged on the frame 1 in a processing sequence. The carton picking device is used to feed a flat carton and convey the carton to the box opening device, the box opening device is used to open the flat carton to form a three-dimensional box body 7, the box loading device is used to feed a workpiece into the three-dimensional box body 7, the box loading conveying device is used to convey the three-dimensional box body along a specific track, and the sealing device is used to press the box cover into the box body 7.

[0031] The specific execution structures and movement steps of the carton picking device, carton opening device, carton loading device, carton conveying device and sealing device in the above-mentioned automated cartoning equipment are as follows:

[0032] Carton picking device

[0033] The carton picking device includes a carton hopper 21 disposed on the frame 1, and a carton grabbing mechanism for receiving a carton at the output end of the carton hopper 21 and moving the carton to a carton opening station. The carton hopper 21 is disposed above the frame 1, and the lower end of the carton hopper 21 is the output end. Cartons in a flat state are stacked in the carton hopper 21. The frame 1 is provided with a support plate 22 at the output end of the carton hopper 21 for supporting the carton in the carton hopper 21. The carton grabbing mechanism includes a material picking moving pair 24 disposed below the carton hopper 21, a rotating pair 25 disposed on the material picking moving pair 24, and an upper suction cup 23 disposed on the rotating end of the rotating pair 25; the upper suction cup 23 uses an air pump to generate negative pressure to absorb and fix the carton, and the upper suction cup 23 can release the carton by controlling the air pump to disconnect. The material picking moving pair 24 refers to a component that can realize reciprocating motion in a straight line direction, and the rotating pair 25 is a component that can realize rotation along the axis. In the embodiment shown in the figure, the material picking moving pair 24 includes a longitudinal track arranged on the frame 1, a longitudinal moving plate 241 arranged on the longitudinal track, and a longitudinal moving cylinder 242 whose output end is connected to the longitudinal moving plate 241. When the longitudinal moving cylinder 242 is working, it drives the longitudinal moving plate 241 to move up and down along the longitudinal track. The rotating pair 25 includes a support plate arranged on the longitudinal moving plate 241, a rotating rod 251 hingedly arranged on the support plate, and a rotating motor 252 whose output shaft is connected to the hinged end of the rotating rod 251. Of course, the rotating motor can also be replaced by a rotating cylinder. The rotating motor 252 drives the rotating rod 251 to rotate along its hinge point. A mounting plate is provided on the rotating end of the rotating rod 251, and the upper suction cup 23 is provided on the mounting plate. Based on the above structure, the execution steps of the paper box picking device are as follows: first, the longitudinal moving cylinder 242 in the picking moving pair 24 drives the longitudinal moving plate 241 to move to the highest position, and the upper suction cup 23 adsorbs and fixes the paper box from the output end of the paper box hopper 21; then the longitudinal moving cylinder 242 drives the longitudinal moving plate 241 to move downward and pulls out the adsorbed and fixed paper box; at the same time, the rotating motor 252 in the rotating pair 25 drives the rotating rod 251 to rotate, so that the upper suction cup 23 and the adsorbed paper box are rotated to the opening station of the box opening device.

[0034] Box opening device

[0035] like Figure 3 and Figure 4As shown, in one embodiment, the box opening device includes a positioning block 31 fixed on the box opening station, and the positioning block 31 serves as a blocking member for the carton picking device to transport the carton to the box opening station, and has the function of propping up the flat carton. In the specific implementation process, refer to the execution steps of the above-mentioned carton picking device, and at the end of the above-mentioned execution steps, the upper suction cup 23 and the carton adsorbed thereon rotate to the end of the box opening station of the box opening device, and the positioning block 31 abuts against the carton and blocks the carton from continuing to rotate. After the side of the carton in the flat state is blocked, the upper suction cup 23 drives the carton to continue to squeeze the positioning block 31. Since the upper suction cup 23 only adsorbs the upper end surface of the carton and rotates to the bottom, the adsorption surface is the upper end surface. During the continued squeezing process, the side wall of the carton turns down and abuts against the positioning block 31, and then becomes vertical, so that the lower end surface of the carton is separated from the upper end surface, and the carton is in an open state. In another embodiment as shown in 2 and 5, the box opening device includes a lower suction cup 32, a drive assembly and a positioning block assembly, wherein the lower suction cup 32 is located in the box opening station and is arranged on the working end of the drive assembly. Under the action of the drive assembly, the lower suction cup 32 can move forward and downward; the specific movement of the lower suction cup can be a linear downward tilt movement or an arc-shaped downward swing. The positioning block assembly includes a positioning block 31 arranged in the box opening station, and a positioning cylinder 33 connected to the positioning block 31 at the output end; the positioning cylinder 33 drives the positioning block 31 to move back and forth in a straight line direction, so that the positioning block 31 approaches or moves away from the lower suction cup 32. The above-mentioned lower suction cup 32 is used to adsorb and fix the lower end surface of the paper box in a flat state. Since the paper box needs to be opened by the coordinated movement of the upper suction cup 23 and the lower suction cup 32, the lower suction cup 32 needs to be able to achieve movement in the downward direction. Because the upper and lower end faces of the flat paper box are staggered, vertical downward movement can only make the paper box appear in a parallelogram shape after opening. Therefore, the lower suction cup 32 uses an arc or a straight line to move forward and downward to align the upper and lower end faces of the paper box after opening, so that the paper box appears in a rectangular shape after opening. Furthermore, in order to ensure that the paper box is rectangular in the final opened state, a positioning block assembly is provided; when the lower suction cup 32 cooperates with the upper suction cup 23 to open the paper box, the positioning cylinder 33 drives the positioning block 31 to approach the paper box in a straight line direction and abut against the side wall of the paper box to keep the side wall of the paper box in a vertical state. Based on the above technical solution, one implementation scheme of the drive assembly is shown in the attached figure. Figure 2 and attached Figure 5As shown, it includes a driving cylinder 34 fixed on the frame 1, a first link 35 arranged on the output end of the driving cylinder 34, a first swing rod 36 and a second swing rod 37 whose lower ends are respectively hinged on the frame 1, and a second link 38 connected and fixed to the swing end of the second swing rod 37. Among them, the driving cylinder 34 is arranged horizontally, and the two ends of the first link 35 are respectively hinged to the output end of the driving cylinder 34 and the swing end of the first swing rod 36; the first swing rod 36 is provided with a linear slide 361, and the second swing rod 37 is provided with a slide column 371 for clamping into the linear slide 361 and moving along the linear slide 361. The lower suction cup 32 is fixed on the second link 38, and a workbench 11 is provided on the frame 1, and the box opening station is located on the workbench 11. The workbench 11 is provided with a linear through hole 12, and the lower suction cup 32 is located in the linear through hole 12 and can move forward and downward. When the carton picking device transports the carton to the preset position, when the box opening device is running, it is first output by the driving cylinder 34, and the output shaft of the driving cylinder 34 is pulled backward horizontally, and the first swing rod 36 is lifted backward along its hinged end by the first link 35, and the second swing rod 37 is further lifted backward along its hinged end, and the lower suction cup 32 moves to the highest position of the motion track, and the lower suction cup 32 adsorbs and fixes the lower end surface of the carton. Then, the output shaft of the driving cylinder 34 is pushed forward horizontally, and the first swing rod 36 is tilted forward along its hinged end by the first link 35, and the second swing rod 37 is further tilted forward along its hinged end, and the lower suction cup 32 moves to the lowest position of the motion track and opens the carton preliminarily. Another embodiment of the driving assembly can be a driving cylinder with an inclined setting, and the output end of the driving cylinder is tilted downward or tilted upward, and the lower suction cup is directly connected to the output end of the driving cylinder, and the driving cylinder can directly drive the lower suction cup 32 to move forward and downward when outputting or resetting. After the paper box is initially opened by the cooperation of the upper suction cup 23 and the lower suction cup 32, the positioning cylinder 33 drives the positioning block 31 to approach the paper box in a straight line direction and abut against the side wall of the paper box, so that the side wall of the paper box remains vertical and the paper box is fully opened. (In addition, a detection sensor can be added to the scheme for box opening detection. Since the lower suction cup moves at an angle, it is not necessary to drive the positioning cylinder 33, and the side wall of the paper box 31 can also be actively approached and abutted.

[0036] Cartoning device

[0037] The box loading device includes an introduction sheet 41 that can extend into the interior of the paper box, and a box loading component that can be used to push the workpiece into the interior of the paper box along the introduction sheet 41. Figure 2 and Figure 5As shown, after the carton is fully opened by the above-mentioned carton opening device, the cartoning process is directly carried out at the carton opening station. The guide plate 41 moves and extends into the carton, and in the preferred embodiment, the guide plate 41 can move longitudinally so that it can be pressed down to the bottom of the carton after extending into the carton. On the one hand, the guide plate 41 serves as a lateral support skeleton inside the carton to prevent the carton from deforming during the cartoning process; on the other hand, the guide plate also serves as a bottom plate for pushing the workpiece, which has the function of pressing the box body and the box cover, as well as guiding. After the above-mentioned guide plate 41 extends into the carton, the cartoning assembly pushes the workpiece into the carton to complete the cartoning action; finally, the cartoning assembly and the guide plate 41 are reset in sequence.

[0038] In a specific embodiment, the frame 1 is provided with a transverse moving pair, and a longitudinal moving pair and a box loading assembly arranged on the transverse moving pair. The transverse moving pair is used to control the introduction piece 41 to extend into or out of the paper box, and the transverse moving pair includes a transverse slide rail 42, a transverse sliding plate 43 arranged on the transverse slide rail 42, and a transverse cylinder 44 whose output end is connected to the transverse sliding plate 43; the transverse cylinder 44 drives the transverse sliding plate 43 to move and is arranged on the transverse slide rail 42. The longitudinal moving pair is used to control the introduction piece 41 to move in the longitudinal direction, so that the introduction piece 41 can be pressed down to the bottom of the paper box; the transverse sliding plate 43 is also provided with a longitudinal support plate 45, and the longitudinal moving pair includes a longitudinal slide rail arranged on the longitudinal support plate 45, a longitudinal sliding block 46 arranged on the longitudinal slide rail, and a longitudinal cylinder whose output end is connected to the longitudinal sliding block 46; the longitudinal cylinder drives the longitudinal sliding block 46 to move on the longitudinal slide rail. The introduction piece 41 is arranged on the longitudinal moving pair, and is specifically arranged on the top of the longitudinal sliding block 46 of the longitudinal moving pair. In a further embodiment, the box loading assembly is arranged on the longitudinal support plate 45, and the box loading assembly includes a box loading bottom plate 47, a box loading cylinder 48 arranged on the box loading bottom plate 47, and a box loading push rod 49 connected to the output end of the box loading cylinder 48; the box loading bottom plate 47 is on the same horizontal plane as the box opening station on the workbench 11, the pushing direction of the box loading push rod 49 points to the introduction sheet 41, and the two ends of the pushing direction of the box loading push rod 49 are provided with side blocks 40, and the two side blocks 40 constitute the loading station of the workpiece, and the workpiece is placed on the loading station manually or automatically by equipment. After the above-mentioned introduction sheet 41 extends into the interior of the paper box and presses down to the bottom of the paper box, the box loading cylinder 48 drives the box loading push rod 49 to push the workpiece into the interior of the paper box along the introduction sheet 41.

[0039] Box conveyor

[0040] After the above-mentioned carton material taking, carton opening and workpiece boxing steps, the box conveying device in this scheme is used to convey the three-dimensional box body 7 loaded with workpieces from the box opening station to the sealing station. In a further preferred embodiment, a precision pressing station is also provided downstream of the sealing station in the sealing device. Therefore, the box conveying device not only needs to push the carton from the box opening station to the sealing station, but also needs to push the carton on the sealing station to the precision pressing station. In a specific embodiment, a linear through-hole slideway 13 is provided on the workbench 11, and the box conveying device includes a pushing component arranged in the linear through-hole slideway 13, and the pushing component can push the carton loaded with workpieces forward from the box opening station to the sealing station along the linear through-hole slideway 13, and push the carton on the sealing station to the precision pressing station. In a specific implementation scheme, the push assembly includes a front push plate 51 at the front side of the carton, and a rear push plate 52 at the rear side of the carton; the rear push plate 52 is used to push the carton from the opening station to the sealing station, the front push plate 51 is used to push the carton on the sealing station to the coining station, and the carton downstream of the coining station is stacked and pushed to the unloading station. Further, the combination of the front push plate 51 and the rear push plate 52 can position the carton, and the front push plate 51 and the rear push plate 52 can be arranged at multiple locations on the same component, such as multiple U-shaped ends of a U-shaped component. In order to avoid the front push plate 51 from bringing the carton back when resetting, the front push plate 51 and the rear push plate 52 can also move longitudinally along the linear through-hole slideway 13, so that the front push plate 51 and the rear push plate 52 can be lowered to the bottom of the workbench 11 for resetting. In a specific implementation scheme, a lateral feeding pair is provided on the frame 1 below the workbench 11, and a longitudinal feeding pair is provided on the lateral feeding pair.

[0041] Sealing device

[0042] The sealing device is used to press the lids at both ends of the paper box into the box body 7, and the sealing device includes a rear wing folding component, a front wing folding component, a lid folding mechanism, a precision pressing mechanism and a positioning mechanism. Since the paper box has openings on both sides, and both openings need to be sealed with lids, in the above mechanism, the rear wing folding component, the front wing folding component, the lid folding mechanism and the precision pressing mechanism are all two groups, and are respectively arranged on both sides of the linear through hole slide 13, for respectively sealing the openings on both sides. Further, since the lids of the openings on both sides of the paper box are respectively connected to the upper side edge and the lower side edge, the setting structure of the lid folding mechanism on both sides is somewhat adjusted, which is specifically recorded below.

[0043] The rear wing folding component is arranged corresponding to the box opening station. After the box loading push rod 49 pushes the workpiece into the inside of the box along the guide piece 41, the output end of the rear wing folding component acts on the rear wing 71 of the box, so that the rear wing of the box is folded toward the inside of the box. In the specific embodiment shown in the figure, the rear wing folding component is a rear wing folding cylinder 61, and the output end of the rear wing folding cylinder 61 faces the rear wing of the box in the box opening station. The front wing folding component is arranged beside the linear through-hole slideway 13 between the box opening station and the sealing station. When the pushing component in the box loading conveying device pushes the box forward to the sealing station along the linear through-hole slideway 13, the front wing folding component acts on the front wing 72 of the box, so that the front wing of the box is folded toward the inside of the box. In the specific implementation scheme shown in the figure, the front wing folding component is specifically a front wing guide block 62, and a guide slope 621 is provided on the front wing guide block 62; when the paper box is pushed forward, the front wing of the paper box is against the front wing guide block 62, and in the process of continuing to move forward, the front wing is pressed and folded into the paper box.

[0044] In this embodiment, the positioning mechanism is arranged corresponding to the sealing station, and is used to position the paper box containing the workpiece in the sealing station to complete the sealing process. The structure of the positioning mechanism is not unique, such as Figure 2 and 6 In the embodiment shown, the positioning mechanism includes a positioning bracket 631 arranged above the sealing station, a lifting pair 632 arranged on the positioning bracket 631, and a positioning clamping block 633 arranged on the lifting pair 632; wherein the lifting pair 632 can be directly driven by a lifting cylinder to drive the positioning clamping block 633 to lift and lower, or a lifting track can be arranged on the positioning bracket 631, a lifting plate is arranged on the lifting track, and the positioning clamping block 633 is arranged at the lower end of the lifting plate. The positioning clamping block 633 is as shown in FIG. Figure 2 The U-shaped clamping block is shown in the figure. The U-shaped opening of the positioning clamping block 633 is used to clamp the top surface and two side surfaces of the paper box to position the paper box.

[0045] The box cover folding mechanism is arranged corresponding to the sealing station, and the box cover folding mechanism is used to fold the box cover 73 of the paper box into the inside of the paper box. The box cover folding mechanism includes a box cover folding assembly capable of folding the box cover, a steel needle 66 capable of guiding the folding of the box cover, and a box cover pressing assembly for pressing the box cover into the inside of the paper box. As mentioned above, since the box covers opened on both sides of the paper box are respectively connected to the upper edge and the lower edge, the setting structure of the box cover folding mechanism on both sides is somewhat adjusted, which is specifically reflected in the output direction of the box cover folding assembly. In the box cover folding mechanism on the upper edge side of the paper box, the box cover folding assembly is above the sealing station, and its output end faces downward; the output end of the box cover folding assembly presses the box cover downward to make it turn down. In the box cover folding mechanism on the lower edge side of the paper box, the box cover folding assembly is below the sealing station, and its output end faces upward; the output end of the box cover folding assembly presses the box cover upward to make it turn up. The following description takes the box cover folding mechanism located on one side of the lower edge of the paper box as an example, that is, the box cover folding assembly is located below the sealing station; the description of the box cover folding mechanism on the other side is omitted. In the box cover folding mechanism, the box cover folding assembly includes a box cover folding cylinder 64 and a box cover folding push rod 65 arranged on the output end of the box cover folding cylinder 64; the output end of the box cover folding push rod 65 faces the steel needle 66, and a positioning step 651 is provided on the output end of the box cover folding push rod 65 for matching with the steel needle 66; when the paper box is conveyed to the sealing station, the paper box cover is under the steel needle 66, and when the box cover folding cylinder 64 drives the box cover folding push rod 65 to output upward, the box cover folding push rod 65 pushes the box cover to flip up; the axial direction of the steel needle 66 is consistent with the track direction of the straight through hole slide 13, and the position of the steel needle 66 is consistent with the fold line of the box cover, and the front side of the fold line of the box cover is the cover tongue 74, and when the box cover contacts the steel needle 66, the box cover folding push rod 65 cooperates with the steel needle 66 to make the cover tongue 74 at the end of the box cover flip toward the paper box opening. Further, the box cover press-fit assembly moves to press the box cover into the carton opening. In the embodiment shown in the figure, the box cover press-fit assembly includes a box cover press-fit block 67, and a box cover press-fit cylinder 68 that drives the box cover press-fit block 67 to move. The box cover press-fit cylinder 68 drives the box cover press-fit block 67 to move close to or away from the carton opening. As recorded above, in the box cover folding step, the position of the steel needle 66 is consistent with the folding line of the box cover, so at this time, the steel needle 66 is far away from the carton opening, and the steel needle 66 is on the inner side of the box cover. If the position of the steel needle 66 is constant, the box cover cannot be pressed into the carton opening, so the steel needle 66 needs to be movably arranged and can move close to or away from the carton opening. In the scheme shown in the figure, the steel needle 66 is arranged on the press-fit auxiliary slider 661, and the press-fit auxiliary slider 661 is driven by the press-fit auxiliary cylinder 662, so that the steel needle 66 can move close to or away from the carton opening. As shown, the front wing guide block 62 is also arranged on the press-fit auxiliary slider 661.Furthermore, since the box cover pressing block 67 needs to pass through the box cover pressing push rod 65, a notch 671 matching the box cover pressing push rod 65 is provided on the box cover pressing block 67. During the operation of the box cover pressing block 67, the box cover pressing block 67 first passes through the box cover pressing push rod 65, and then cooperates with the steel needle 66 to clamp the box cover, and the box cover pressing block 67 and the steel needle 66 operate synchronously to press and fold the box cover into the paper box. In order to ensure that the end of the box cover is always folded toward the opening of the paper box, a notch 672 matching the steel needle 66 is provided on the box cover pressing block 67.

[0046] After the above-mentioned box cover is pressed, although the end of the box cover is already inside the paper box, since the steel needle 66 is still inserted into the inside of the box cover, the above-mentioned structure cannot completely press the box cover into the paper box to complete the box loading; further precision pressing is required. As mentioned above, after the above-mentioned sealing station is processed, the positioning mechanism releases the positioning, and the front push plate 51 pushes the paper box on the sealing station to the precision pressing station. Since the axial direction of the steel needle 66 is consistent with the track direction of the linear through-hole slideway 13, the steel needle 66 withdraws from the inside of the box cover during the process of pushing the paper box to the precision pressing station; the precision pressing mechanism performs precision pressing on the paper box at the precision pressing station to complete all the box loading steps. The precision pressing mechanism shown in the figure includes a precision pressing cylinder 691 and a precision pressing block 692 arranged on the output end of the precision pressing cylinder 691. After the above-mentioned precision pressing process, the finished products are stacked and pushed forward in sequence, and unloaded at the unloading station.

[0047] Based on the above-mentioned automated box packaging equipment, the specific operating steps are as follows:

[0048] 1. The longitudinal moving cylinder 242 in the material picking moving pair 24 drives the longitudinal moving plate 241 to move to the highest position, and the upper suction cup 23 absorbs and fixes the paper box from the output end of the paper box hopper 21.

[0049] 2. The longitudinal moving cylinder 242 drives the longitudinal moving plate 241 to move downward and pull out the adsorbed and fixed paper box; at the same time, the rotating motor 252 in the rotating pair 25 drives the rotating rod 251 to rotate, so that the upper suction cup 23 and the adsorbed paper box rotate to the opening station of the opening device.

[0050] 3. The drive cylinder 34 outputs, and the output shaft of the drive cylinder 34 is pulled backward horizontally, and the first swing rod 36 is lifted backward along its hinged end through the first link 35, and the second swing rod 37 is further lifted backward along its hinged end, and the lower suction cup 32 moves to the highest position of the parabola trajectory, and the lower suction cup 32 fixes the lower end surface of the paper box. Then, the output shaft of the drive cylinder 34 is pushed forward horizontally, and the first swing rod 36 is tilted forward along its hinged end through the first link 35, and the second swing rod 37 is further tilted forward along its hinged end, and the lower suction cup 32 moves to the lowest position of the parabola trajectory and the paper box is initially opened;

[0051] 4. The positioning cylinder 33 drives the positioning block 31 to approach the paper box in a straight line direction and abut against the side wall of the paper box, so that the side wall of the paper box remains in a vertical state and the paper box is fully opened.

[0052] 5. The lateral moving pair operates to move the guide piece 41 into the paper box; the longitudinal moving pair operates to press the guide piece 41 down to the bottom of the paper box; then, the box loading cylinder 48 drives the box loading push rod 49 to push the workpiece along the guide piece 41 into the paper box.

[0053] 6. The upper suction cup 23 is removed and reset, and the guide piece 41 is withdrawn and reset.

[0054] 7. The output end of the rear wing folding component acts on the rear wing of the paper box, causing the rear wing of the paper box to fold toward the inside of the paper box.

[0055] 8. The box conveying device conveys the three-dimensional box body 7 loaded with the workpiece forward, and the front wing folding component acts on the front wing of the paper box to fold the front wing of the paper box toward the inside of the paper box.

[0056] 9. The box conveying device conveys the three-dimensional box body 7 loaded with workpieces to the sealing station, and the positioning mechanism positions the paper box loaded with workpieces in the sealing station.

[0057] 10. When the cover folding cylinder 64 drives the cover folding push rod 65 to output upward, the cover folding push rod 65 pushes the cover to flip up; the axial direction of the steel needle 66 is consistent with the track direction of the straight through hole slide 13, and the position of the steel needle 66 is consistent with the folding line of the cover. When the cover contacts the steel needle 66, the cover folding push rod 65 cooperates with the steel needle 66 to fold the end of the cover toward the opening of the paper box.

[0058] 11. During the operation of the box cover pressing block 67, the box cover pressing and folding push rod 65 is first passed, and then the box cover is clamped and installed in cooperation with the steel needle 66. The box cover pressing and folding block 67 and the steel needle 66 operate synchronously to press and fold the box cover into the paper box, completing the initial pressing and installation.

[0059] 12. The positioning mechanism releases the positioning, and the front push plate 51 pushes the paper box on the sealing station to the embossing station. Since the axial direction of the steel needle 66 is consistent with the track direction of the straight through-hole slide 13, the steel needle 66 withdraws from the inside of the box cover during the process of pushing the paper box to the embossing station.

[0060] 13. The embossing mechanism embosses the paper box at the embossing station to complete the cartoning step.

[0061] 14. The finished products are stacked and pushed forward one by one and unloaded at the unloading station.

[0062] Embodiment 2:

[0063] The specific solution of this embodiment is as follows Fig. 9As shown, the automated box-packing equipment in this embodiment adopts a multi-station solution on the frame (this description does not include the coining station); in Example 1, the solution includes a box-opening station and a sealing station, and both the box-opening device and the box-loading device work at the box-opening station. In this solution, a multi-station structure of a box-opening station, a box-loading station, front and rear wing sealing, and a sealing station is adopted. The difference is that the box-opening device works at the box-opening station, and the box-loading device works at the box-loading station. Through the above improvements, the box-opening device and the box-loading device can run synchronously without a sequence, thereby improving the working efficiency of the automated box-packing equipment. Therefore, the difference between the solution of this embodiment and the solution of Example 1 is only the change in the increase of the above-mentioned box-loading station, and the structural adjustment of the box-packing conveying device and the positioning mechanism due to the change in the increase of the box-loading station; the remaining structures can refer to the contents recorded in Example 1, which will not be described in detail here.

[0064] Specifically in this embodiment, a workbench 11 is provided on the frame 1, and the workbench 11 is provided with a box opening station, a box loading station, front and rear wing sealing and a sealing station in a straight line direction; the carton picking device is used to feed a flat carton and transport the carton to the box opening station, the box opening device is used to open the flat carton at the box opening station to form a three-dimensional box body, the box loading device is used to feed the workpiece into the three-dimensional box body 7 at the box loading station, and the sealing device is used to press the box cover into the box body 7 at the sealing station. The box loading conveying device in this scheme is used to transport the box body 7 opened in a three-dimensional shape from the box opening station to the box loading station, and to transport the three-dimensional box body 7 loaded with the workpiece from the box loading station to the sealing station. In a specific embodiment, a linear through-hole slideway 13 is provided on the workbench 11, and the box loading conveying device includes a pushing component arranged in the linear through-hole slideway 13. The pushing assembly includes a front push plate 51 at the front side of the carton, and a rear push plate 52 at the rear side of the carton; the rear push plate 52 is used to push the carton from the carton opening station to the carton loading station, and the front push plate 51 is used to push the carton on the carton loading station to the sealing station, and the carton downstream of the sealing station is pushed out by stacking. In addition, when the carton loading device and the sealing device are working, the box body needs to be positioned. In Example 1, when the carton loading device is working, the box body provides upper suction cups, lower suction cups, positioning blocks and other coordinated positioning, so the positioning mechanism in its scheme only needs to correspond to the sealing station setting. In this embodiment, the box body also needs to be positioned at the carton loading station to cooperate in completing the carton loading process. As shown specifically Fig. 9 As shown, the positioning clamping block 633 of the positioning mechanism includes two positioning ends. The positioning clamping block 633 in the figure is provided with two clamping openings, which correspond to the box loading station and the sealing station respectively, and are used to clamp the top surface and two side surfaces of the paper box to position the paper box. Of course, those skilled in the art can also set two sets of independently operated positioning mechanisms to correspond to the box loading station and the sealing station respectively as needed.
