Description

Technical Field

[0001] The present invention relates to the technical field of packaging and filling equipment, and in particular to a box packaging equipment and a use method thereof. Background Art

[0002] The progress of the packaging industry has greatly promoted the development of industries such as food and daily chemicals. The development of these industries in turn has further driven the demand for the packaging market, giving the packaging industry a huge market impetus. With the development of functional packaging materials and the continuous improvement of processing technology, packaging is playing an increasingly important role in many fields. Cartons are a common packaging material for product packaging. Cartons are usually folded into a flat shape when they are received. When they need to be packed, they need to be folded into a box shape according to the pre-bending line. If this process is performed manually, it will not only be costly, slow, and inefficient, but also have a high error rate in the process of packing materials or semi-finished products. Therefore, an automated loading process is required to improve production efficiency.

[0003] A Chinese invention patent application with publication number CN114426122A discloses a carton packaging machine, comprising a lower cover folding device, a carton transport mechanism, an upper cover folding device and a positioning mechanism, wherein the lower cover folding device comprises a box opening mechanism, a lower cover-shaking mechanism for shaking a first lower cover and a second lower sub-cover, a folding tongue-closing mechanism for folding a lower cover tongue and pushing a lower main cover to close the cover, and a transferring mechanism, and the upper cover folding device comprises an upper cover-shaking mechanism for shaking a first upper sub-cover and a second upper sub-cover, an upper folding tongue mechanism for folding an upper cover tongue, an upper cover-closing mechanism for pushing an upper main cover to close the cover, a folding lock mechanism for pushing a lock to bend relative to a bending portion, and an inserting lock mechanism for pushing the bending portion to allow the lock to be inserted into an insertion hole. A Chinese utility model patent with announcement number CN208882247U discloses a paper box packaging device with a positioning function, including a body, a workbench welded on the top of the body, support plates welded on the left and right sides of the top of the workbench, a threaded ring welded on the left side of the right support plate, the internal thread of the threaded ring is connected to a threaded rod, an extrusion block is welded on the bottom end of the threaded rod, and a pull block is welded on the end of the threaded rod away from the extrusion block.

[0004] It is not difficult to see from the attached drawings that in the current prior art, the left support plate, the right support plate, and the middle movable plate are very thick and need to be welded and installed on the machine respectively, which is very difficult to operate. Since the left support plate, the right support plate, and the middle movable plate need to carry many working modules, in order to ensure the support strength, the thickness of the left support plate, the right support plate, and the middle movable plate needs to be very thick, so the overall weight of the equipment is very heavy, which is not conducive to lightweight equipment. And because its production line has a certain length, its bottom plate, support plate, etc. are usually spliced ​​by multiple thick plates, and the splicing is easy to cause equipment jamming, increasing the probability of equipment failure.

[0005] The Chinese invention patent application with the publication number CN111114901A discloses an automatic cartoning machine, including a frame and a control panel, on which a motor, a carton magazine, a feeding conveying device, a carton conveying device, a discharging conveying device, a pushing device and a suction cup device are installed, which can realize the automation of carton packaging. However, the current packaging equipment usually assembles each component one by one to the packaging equipment, which is not only difficult to operate, but also creates a great obstacle to the subsequent maintenance and other operations, and is not convenient for production, installation and use. Summary of the invention

[0006] In view of the defects in the prior art, the first object of the present invention is to provide a compact and lightweight automatic cartoning and packaging equipment with pre-assembled functional modules for easy overall installation and subsequent maintenance.

The support legs can not only achieve the lightweight of the packaging equipment but also increase the support strength, and the side is convenient for supplementing the function of the modular workbench. Strengthening the folding edge is convenient for enhancing the overall stability and strength of the modular workbench, and the through hole is convenient for waste disposal and reduces the probability of failure of the modular workbench.

[0015] Furthermore, the packaging box unloading device comprises a box library support base plate, a packaging box library, a packaging box unloading suction cup, and a unloading suction cup adjustment member;

[0016] The packaging box warehouse comprises a plurality of box warehouse unloading baffles, a baffle position adjusting member, a box warehouse unloading baffle, and a unloading baffle connecting frame;

[0017] The box library support base plate is connected to the workbench, the box library unloading baffle is arranged on the upper end of the box library support base plate, and the end of the unloading baffle connecting frame away from the box library support base plate is connected to the material pushing and box loading device;

[0018] The baffle position adjusting member and the material unloading baffle connecting frame are used to adjust the positions of the box magazine unloading baffle and the box magazine unloading baffle according to the size of the packaging box; the unloading suction cup adjusting member is used to adjust the position of the packaging box unloading suction cup;

[0019] The driving mechanism is used to drive the unloading suction cup adjusting member and the packaging box unloading suction cup to perform reciprocating motion between the packaging box library and the packaging box conveying device.

[0020] Through the above technical solution, the positions of the box magazine unloading baffle bar and the box magazine unloading baffle plate are adjusted according to the size of the packaging boxes, the packaging boxes are placed in the packaging box magazine, and the packaging boxes in the packaging box magazine are grabbed in sequence into the packaging box conveying device through the packaging box unloading suction cup.

[0021] Furthermore, a boxing and packaging channel is formed between the side of the front supporting wall panel close to the product conveying device and the movable wall panel;

[0022] The packaging box conveying device comprises a plurality of inner chain guide bars and a plurality of packaging box guide chains, wherein a plurality of packaging box guide limiters are arranged on the outer circumference of the packaging box guide chain; one end of the packaging box guide limiter is connected to the packaging box guide chain and the other end extends in a direction away from the packaging box guide chain; a guide chain through groove is provided in the middle of the inner chain guide bar, and a guide limiter through groove is provided on the upper surface, and the guide chain through groove is connected to the guide limiter through groove;

[0023] The inner chain guide bars are integrally formed, and the lower surfaces of the two inner chain guide bars on the side away from each other are provided with guide bar clamping grooves, and are respectively clamped with the upper surfaces of the front supporting wall panels and the movable wall panels on both sides of the box loading and packaging channel;

[0024] The number of the inner chain guide bars is two, the number of the packaging box guide chains is four, and two packaging box guide chains are arranged in the guide chain through groove of each inner chain guide bar;

[0025] The packaging box conveying device also includes a packaging box pressure strip and a pressure strip position adjusting member, wherein the number of packaging box pressure strips is two and they are respectively located above the inner chain guide strip, and the pressure strip position adjusting member is used to adjust the distance between the packaging box pressure strip and the inner chain guide strip and the distance between the packaging box pressure strip and the packaging box lowering device;

[0026] A packaging box conveying channel is formed between the two inner chain guide bars and the two packaging box pressing bars, and a packaging box auxiliary unfolding member is provided at one end of the packaging box pressing bar close to the packaging box lowering device;

[0027] The driving mechanism is used to drive the packaging box guide chain to move in the guide chain through slot.

[0028] Through the above technical solution, the packaging boxes in the packaging box library are transported to the box loading and packaging channel and the packaging box auxiliary unfolding parts unfold the flat packaging boxes into a three-dimensional shape. The driving mechanism drives the packaging box guide chain to drive the packaging box to move along the opening direction of the inner chain guide bar. By adjusting the relative positions of the two packaging box guide chains in the same inner chain guide bar, the distance between adjacent packaging box guide limiters is adjusted to adapt to packaging boxes of different sizes.

[0029] The two adjacent packaging box guide limiters, the inner chain guide strip, and the packaging box pressure strip limit the unfolded three-dimensional packaging box in a space, and the packaging box moves along the packaging box conveying channel with the displacement of the packaging box guide limiters.

[0030] The existing inner chain guide bar and even the workbench are commonly assembled by splicing and welding. Replacing them with an integrally formed inner chain guide bar greatly reduces the probability of equipment failure.

[0031] Furthermore, the product conveying device includes a product conveying support frame, a product conveying positioning frame, and a product conveyor belt;

[0032] One end of the product conveying support frame is connected to both sides of the middle of the product conveyor belt, and the other end is connected to the frame; one end of the product conveying positioning frame is connected to one end of the product conveyor belt close to the packaging box conveying device, and the other end is connected to the workbench;

[0033] The outer peripheral side of the product conveying device is provided with a plurality of product conveying baffles along its width direction; the end of the product conveyor belt away from the frame is provided with a protective cover;

[0034] The driving mechanism is used to drive the product conveyor belt to rotate.

[0035] Through the above technical solution, the product conveying device and the packaging box conveying device operate synchronously and intermittently, so that the product and the unfolded three-dimensional packaging box are placed in a straight line.

[0036] Furthermore, the material pushing and box loading device comprises a material pushing and box loading support frame and a material pushing mechanism, a material pressing mechanism, a horizontal displacement track, and a vertical displacement track arranged on the material pushing and box loading support frame;

[0037] The material pushing and box loading support frame is connected to one side of the front supporting wall plate, and a material pushing overload protection mechanism is provided on the lower surface of the material pushing mechanism;

[0038] The driving mechanism drives the pushing mechanism and the pressing mechanism to move along the direction in which the horizontal displacement track is opened and / or along the direction in which the vertical displacement track is opened.

[0039] Through the above technical scheme, the product conveying device and the packaging box conveying device operate synchronously and intermittently. When the product and the unfolded three-dimensional packaging box are in a straight line, the product conveying device and the packaging box conveying device stop moving, the pressing mechanism limits the size of the product in the height direction, and the pushing mechanism pushes the product into the packaging box along the horizontal displacement track. At this time, the pressing mechanism and the pushing mechanism move along the horizontal displacement track away from the packaging box at the same time, and move upward along the vertical displacement track first. At the same time, the product conveying device and the packaging box conveying device operate until the next product and the unfolded three-dimensional packaging box are in a straight line. At this time, the pressing mechanism and the pushing mechanism are reset synchronously and the above operation is repeated.

[0040] It is convenient for the conveyor belt for conveying the packaging boxes and the conveyor belt for conveying the products to continue to move immediately after the pushing mechanism completes the action of pushing the materials into the boxes, without causing the pushing mechanism to collide with the limiting parts and baffles on the conveyor belt for conveying the packaging boxes and the conveyor belt for conveying the products, thereby greatly improving production efficiency.

[0041] Furthermore, the packaging box comprises a box body and two small hinges located at both ends of the box body in the width direction, a large hinge located at both ends of the box body in the height direction, and an inserting tongue at the end of the large hinge;

[0042] The box closing device comprises a small folding mechanism and a large folding mechanism respectively arranged in sequence on both sides of the box loading and packaging passage from the direction close to the box lowering device to the direction away from the box lowering device, and used for closing the box containing the product;

[0043] The small folding mechanism comprises a small folding front folding part and a small folding guide strip which are respectively arranged in sequence from the direction close to the packaging box lower box device to the direction away from the packaging box lower box device; the driving mechanism drives the small folding front folding part to bend the small folding parts at the two ends of the packaging box body in the width direction close to the packaging box lower box device, and the small folding guide strip is used to bend the small folding parts at the two ends of the packaging box body in the width direction away from the packaging box lower box device;

[0044] The large folding mechanism includes a large folding guide plate, a large folding adjustment support strip, and a large folding tongue insertion mechanism; the large folding tongue insertion mechanism includes a front tongue block and a rear tongue block; the large folding guide plate is inclined from the direction close to the packaging box lower box device to the direction away from the packaging box lower box device along the direction of the large folding close to the packaging box to the direction of the large folding away from the packaging box. When the large folding of the packaging box is located between the large folding guide plate and the large folding adjustment support strip, the driving mechanism drives the front tongue block to move in the direction close to the packaging box. When the large folding of the packaging box moves to the space between the large folding guide plate and the large folding adjustment support strip, the driving mechanism drives the rear tongue block to move in the direction close to the packaging box.

[0045] Since the hinges at both ends of the packaging box are usually symmetrical about the midpoint, the large hinge guide plates on both sides of the box loading and packaging channel usually guide in opposite directions. If they are symmetrical about the cross section, the large hinge guide plates can be flipped and installed for use.

[0046] Through the above technical solution, the front folding part of the small hinge bends the small hinge of the packaging box close to the packaging box lower box device. When the packaging box moves along the packaging box conveying channel, the small hinge of the packaging box away from the packaging box lower box device is bent under the action of the small hinge guide strip.

[0047] Then, as the packaging box moves along the packaging box conveying channel, the large hinge is bent along the inclined direction of the large hinge guide plate, and the connection between the large hinge and the inserting tongue is located between the large hinge guide plate and the large hinge adjustment support strip. The driving mechanism drives the front inserting tongue block to bend the inserting tongue relative to the large hinge, and then the large hinge is separated from the large hinge guide plate and the large hinge adjustment support strip, and the driving mechanism drives the rear inserting tongue block to respectively buckle the large hinge and the inserting tongue with the two ends of the box body of the packaging box.

[0048] Furthermore, the packaging box includes a box body and two small hinges located at both ends of the box body in the width direction, and two large hinges located at both ends of the box body in the height direction;

[0049] The box closing device comprises a small folding mechanism, a large folding mechanism, a gluing mechanism, and a large folding mechanism, which are arranged in sequence on both sides of the box loading and packaging passage from the direction close to the box lowering device to the direction away from the box lowering device, and are used to close the box containing the product;

[0050] The small folding mechanism comprises a small folding front folding part and a small folding guide strip which are respectively arranged in sequence from the direction close to the packaging box lower box device to the direction away from the packaging box lower box device; the driving mechanism drives the small folding front folding part to bend the small folding parts at the two ends of the packaging box body in the width direction close to the packaging box lower box device, and the small folding guide strip is used to bend the small folding parts at the two ends of the packaging box body in the width direction away from the packaging box lower box device;

[0051] The driving mechanism drives the two large folding mechanisms on both sides of the box loading and packaging channel close to the lower box device to bend a large hinge at both ends of the box respectively, the driving mechanism drives the gluing mechanism to apply glue on the surface of the bent large hinges, and the driving mechanism drives the two large folding mechanisms on both sides of the box loading and packaging channel away from the lower box device to bend the other two large hinges at both ends of the box and conflict with the glued large hinges.

[0052] Through the above technical solution, the front folding part of the small hinge bends the small hinge of the packaging box close to the packaging box lower box device. When the packaging box moves along the packaging box conveying channel, the small hinge of the packaging box away from the packaging box lower box device is bent under the action of the small hinge guide strip.

[0053] First, a large folding leaf at each end of the packaging box is bent through a set of large folding leaf mechanisms, and then glue is applied to the surface of the bent large folding leaf mechanism through a gluing mechanism. Then, another set of large folding leaf mechanisms is used to bend the other two large folding leaves at both ends of the packaging box and bond them to the glued large folding leaves.

[0054] Furthermore, the box-discharging conveying device includes box-discharging conveying belts respectively arranged on both sides of the box-loading and packaging channel, and the distance between the sides of the two box-discharging conveying belts close to each other is less than or equal to the size of the packaging box in the width direction of the box-loading and packaging channel; the driving mechanism is used to drive the box-discharging conveying belts to move.

[0055] Through the above technical solution, after the product is packaged in the packaging box, it can be easily output from the compact automatic box packaging equipment through the box delivery conveyor.

[0056] The second object of the present invention is to provide a box packaging device and a method of use. The second object of the present invention is achieved through the following technical solution: a box packaging device and a method of use, comprising the following steps:

[0080] Embodiment 1:

[0081] like Figure 1 , Figure 2 As shown, the present embodiment relates to a compact automatic box packing device, comprising a frame 1, a workbench 2 is arranged inside the frame 1, and the workbench 2 can be detachably mounted on the frame 1. The workbench 2 is provided with one or more working modules of a driving mechanism 3, a packing box unloading device 4, a packing box conveying device 5, a product conveying device 6, a material pushing and boxing device 7, a box closing device 8, and a box discharging and conveying device 9, so that most of the devices can be assembled and debugged in advance outside the frame 1, and then directly moved and installed on the packaging device as a whole. Compared with the prior art, the left support plate, the right support plate, and the middle movable plate need to be welded and installed on the machine separately, which is very difficult to install the working modules and is difficult to repair, the installation is more time-saving and labor-saving, and the maintenance is more convenient.

[0082] like Figure 3 , Figure 8As shown, in a specific embodiment, the workbench 2 includes a front support wall panel 21, the cross section of the front support wall panel 21 along its length direction is U-shaped, the front support wall panel 21 is an integrated design and the opening is upward, and a movable wall panel 22 is arranged between the two opposite sides of the front support wall panel 21, and the relative position of the movable wall panel 22 and the front support wall panel 21 is adjusted by two ball screws, one of the two ball screws is a hand screw, and the other is a synchronous screw, and the hand screw and the synchronous screw rotate synchronously through a chain and a gear. There are positioning parts on the two ball screws to fix the movable wall panel 22 after the relative position of the front support wall panel 21 is adjusted appropriately. A plurality of mounting holes and mounting grooves are arranged on the front support wall panel 21 and the movable wall panel 22, so as to facilitate the assembly of the working module on the front support wall panel 21 and the movable wall panel 22, wherein the multiple shafts of the working module can play an auxiliary fixing role.

[0083] like Figure 4 As shown, the upper end of one side of the front supporting wall panel 21 and the lower surface of the movable wall panel 22 are provided with a reinforcing folded edge 24, and the upper surface of the bottom surface of the front supporting wall panel 21 is provided with two through holes 211. Compared with the prior art, the left supporting plate, the right supporting plate, and the middle movable plate are very thick and need to be welded and installed on the machine respectively.

[0097] When the product and the unfolded three-dimensional packaging box 81 are in a straight line, the product conveying device 6 and the packaging box conveying device 5 stop moving, the driving device causes the pressing mechanism 73 to limit the product height dimension through the transmission mechanism 31, and the pushing mechanism 72 pushes the product into the packaging box 81 along the horizontal displacement track 74. At this time, the pressing mechanism 73 and the pushing mechanism 72 simultaneously move along the horizontal displacement track 74 in a direction away from the packaging box 81, and first move upward along the vertical displacement track 75. At the same time, the product conveying device 6 and the packaging box conveying device 5 operate until the next product and the unfolded three-dimensional packaging box 81 are in a straight line. At this time, the pressing mechanism 73 and the pushing mechanism 72 are synchronously reset and the above operation is repeated. It is convenient for the conveyor belt conveying the packaging box 81 and the conveyor belt conveying the product to continue to move immediately after the pushing mechanism 72 completes the action of pushing the material into the box, without causing the pushing mechanism 72 to collide with the limiting parts and baffles on the conveyor belt conveying the packaging box 81 and the conveyor belt conveying the product, thereby greatly improving production efficiency.

[0098] like Figure 6 , Figure 7 As shown, after the product enters the packaging box 81, the packaging box 81 is closed by the box closing device 8. When the packaging box 81 includes a box body and two small hinges 811 located at both ends of the box body in the width direction, a large hinge 812 located at both ends of the box body in the height direction, and an inserting tongue 813 at the end of the large hinge 812, the box closing device 8 includes a small hinge mechanism 82 and a large hinge mechanism 83 respectively arranged in sequence on both sides of the box loading and packaging channel from the direction close to the packaging box lower box device 4 to the direction away from the packaging box lower box device 4.

When the large folding leaf 812 of the packaging box 81 is located between the large folding guide plate 831 and the large folding adjustment support strip 832, the driving mechanism 3 drives the front tongue block 8331 to move in the direction close to the packaging box 81. When the large folding leaf 812 of the packaging box 81 moves to the space between the large folding guide plate 831 and the large folding adjustment support strip 832, the driving mechanism 3 drives the rear tongue block 8332 to move in the direction close to the packaging box 81.

[0101] When in use, the front folding part 821 of the small hinge bends the small hinge 811 of the packaging box 81 close to the packaging box lower box device 4, and when the packaging box 81 moves along the packaging box conveying passage, the small hinge 811 of the packaging box 81 away from the packaging box lower box device 4 is bent under the action of the small hinge guide strip 822. Then, as the packaging box 81 moves along the packaging box conveying passage, the large hinge 812 is bent along the direction in which the large hinge guide plate 831 is inclined, and the connection between the large hinge 812 and the plug tongue 813 is located between the large hinge guide plate 831 and the large hinge adjustment support strip 832, and the driving mechanism 3 drives the front plug tongue block 8331 to bend the plug tongue 813 relative to the large hinge 812, and then the large hinge 812 is separated from the large hinge guide plate 831 and the large hinge adjustment support strip 832, and the driving mechanism 3 drives the rear plug tongue block 8332 to buckle the large hinge 812 and the plug tongue 813 with the two ends of the box body of the packaging box 81.

The driving mechanism 3 drives the two large folding mechanisms 83 on both sides of the box loading and packaging channel away from the packaging box lower box device 4 to bend the other two large hinges 812 at both ends of the packaging box 81 and conflict with the glued large hinges 812.

[0105] When in use, the small hinge front folding portion 821 bends the small hinge 811 of the packaging box 81 close to the packaging box lower box device 4, and when the packaging box 81 moves along the packaging box conveying channel, the small hinge 811 of the packaging box 81 away from the packaging box lower box device 4 is bent under the action of the small hinge guide strip 822. First, a large hinge 812 at both ends of the packaging box 81 is bent by a set of large hinge mechanisms 83, and then the surface of the bent large hinge mechanism 83 is coated with glue by a gluing mechanism, and then the other two large hinges 812 at both ends of the packaging box 81 are bent by another set of large hinge mechanisms 83 and bonded to the glued large hinges 812.

[0106] Finally, after the product is packed in the packaging box 81, it is convenient to be output from the compact automatic box packing device through the box discharging conveyor device 9. The box discharging conveyor device 9 includes box discharging conveyor belts 91 respectively arranged on both sides of the box packing passage, and the distance between the sides of the two box discharging conveyor belts 91 close to each other is less than or equal to the size of the packaging box 81 in the width direction of the box packing passage; the driving mechanism 3 is used to drive the box discharging conveyor belts 91 to move.

[0112] C. Under the action of the driving device and the transmission mechanism indexing machine, the product conveying device and the packaging box conveying device operate synchronously and intermittently, placing the product and the unfolded three-dimensional packaging box in a line.

[0113] D. When the product and the unfolded three-dimensional packaging box are in a straight line, the product conveying device and the packaging box conveying device stop moving, the driving device uses the transmission mechanism to limit the height dimension of the product by the pressing mechanism, and the pushing mechanism pushes the product into the packaging box along the horizontal displacement track. At this time, the pressing mechanism and the pushing mechanism move away from the packaging box along the horizontal displacement track at the same time, and move upward along the vertical displacement track first. At the same time, the product conveying device and the packaging box conveying device run until the next product and the unfolded three-dimensional packaging box are in a straight line.
