Description

Technical Field

[0001] The present invention relates to the technical field of corrugated paper box production, and more specifically, to a corrugated paper box overturning and packing device and a packing method. Background Art

[0002] At the back end of the automatic production line for corrugated paper boxes, the finished corrugated paper boxes need to be packaged, stacked and sent to customers. The general process of the back end of the automatic production line for corrugated paper boxes includes: conveying and loading, automatic counting, automatic bundling and flipping and stacking. The finished corrugated paper boxes (unopened) are counted one by one by the counting machine through the conveying mechanism, and then conveyed to the automatic bundling mechanism. A set number of finished corrugated paper boxes are all stacked and bundled with their front sides facing up into a packaging unit (for example, each packaging unit includes 20 finished corrugated paper boxes). Since the humidity of the newly produced finished corrugated paper boxes is relatively high, in order to avoid the bending and warping of the finished corrugated paper boxes during stacking, the prior art stacks the packaging units in an alternating manner of one packaging unit facing up and one packaging unit facing down, that is, the first packaging unit is placed on the pallet with its front side facing up, and the second packaging unit is flipped by the flipping mechanism to face down and placed above the first packaging unit, and the stacking of all packaging units is completed by analogy.

[0003] Referring to a simple logistics-type turning machine and an automatic turning method for a stack of corrugated cardboard disclosed in publication number CN112093519B, the turning mechanism of the prior art mainly includes two sets of cross-lapped front and rear turning frames and a lever. When operating, the front and rear turning frames are first rotated to form a V-shaped structure, and then the cardboard slides from the front turning frame close to the paper receiving platform (equivalent to the above-mentioned conveying mechanism) into the V-shaped structure obliquely from above. At this time, the cardboard and the front turning frame have the same inclination angle and the top of the cardboard protrudes outside the V-shaped structure. The top of the cardboard is pushed from above by the lever to turn it to the rear turning frame. Finally, the front and rear turning frames are reset to a horizontal state to complete the 180-degree turning of the cardboard. The prior art has the advantages of simple structure, small footprint, low manufacturing cost, and low malfunction. It should be noted that if the cardboard is first placed on the front turning frame and then the front and rear turning frames are turned over, as the angle of the V-shaped structure gradually decreases and the cardboard slides toward the bottom of the V-shaped structure, the front and rear turning frames will squeeze the cardboard. Therefore, the prior art should operate in accordance with the above sequence, that is, the cardboard slides from the oblique upper part of the front turning frame into the interior of the V-shaped structure.

[0004] When the above-mentioned cardboard is a packing unit, since the packing unit has multiple stacked finished corrugated paper boxes (a single finished corrugated paper box is equivalent to a cardboard), when the packing unit slides down along the inclined surface of the front turning frame, since the finished corrugated paper boxes at the lower layer are in direct contact with the inclined surface and generate friction, when the packing unit is heavy, the finished corrugated paper boxes at the lower layer of the packing unit will be damaged by plane friction, and at the same time, the strapping belt and the inclined surface of the front turning frame will also be in contact with plane friction, which may cause the strapping belt and the inclined surface to be relatively still and tighten the packing unit to produce marks in severe cases, which may not only damage the finished corrugated paper boxes at the upper layer of the packing unit, but also stop the packing unit from sliding down the inclined surface of the front turning frame, thereby increasing the unqualified rate of the packing unit.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Refer to the instruction manual Figures 1 to 7A corrugated paper box flipping and packaging device includes a flipping mechanism 1, and the flipping mechanism 1 is located between a paper receiving mechanism 2 and a stacking mechanism 3. The packaging unit 9 on the paper receiving mechanism 2 moves from a paper receiving platform 21 to the flipping mechanism 1. The flipping mechanism 1 is used to flip the packaging unit 9 and stack the flipped packaging unit 9 on a lifting platform 31 through the stacking mechanism 3; the flipping mechanism 1 includes a main frame plate 11, one end of the main frame plate 11 is installed with a first fixed plate 12, the first fixed plate 12 is installed with a front flipping frame 4, and the front flipping frame 4 is provided with at least two groups, and the end of the main frame plate 11 close to the first fixed plate 12 is installed with a rolling support mechanism 7; the rolling support mechanism 7 includes a support The support wheel 71 is located between two adjacent groups of front flip frames 4. The rolling support mechanism 7 also includes a connecting plate 72. A guide plate 73 is fixedly provided at one end of the connecting plate 72. The guide plate 73 is arranged in an arc shape. A wheel axle 74 is slidably connected to one side of the guide plate 73. The wheel axle 74 passes through the center of the support wheel 71. When the front flip frame 4 rotates, the wheel axle 74 is driven to slide along the direction of the guide plate 73. A guide groove 731 is provided inside the guide plate 73. One end of the guide plate 73 is slidably arranged inside the guide groove 731. A locking assembly is installed inside the guide groove 731. The locking assembly is used to position one end of the guide plate 73 inside the guide groove 731.

[0035] It should be noted that the front flip frame 4 is the prior art mechanism mentioned in the background technology, including a motor, a belt and a support frame, the support frame is rotatably connected to the first fixed plate 12, and when the front flip frame 4 is in the horizontal state, the support wheel 71 is located below the front flip frame 4, that is, the support wheel 71 does not contact the bottom surface of the packaging unit 9, and when the front flip frame 4 is in the inclined state, the upper half of the support wheel 71 protrudes above the front flip frame 4, that is, the bottom surface of the packaging unit 9 directly contacts the upper half of the support wheel 71.

[0036] In this embodiment, the implementation scenario is specifically as follows: the front flip frame 4 rotates toward the bottom of the first fixed plate 12 and is in an inclined state, and the packaging unit 9 after bundling is completed at the paper receiving mechanism 2 moves toward the inclined front flip frame 4. After the bottom of the front flip frame 4 contacts the wheel shaft 74, the upper half of the support wheel 71 protrudes from the top of the front flip frame 4, and the inclination angle of the front flip frame 4 is adjusted. The positions of the wheel shaft 74 and the support wheel 71 are positioned by the locking assembly. At this time, under the support of the support wheel 71, the packaging unit 9 slides down from the top of the front flip frame 4, and the plane friction between the front flip frame 4 and the packaging unit 9 is changed to the rolling friction between the support wheel 71 and the packaging unit 9, thereby preventing the finished corrugated paper box at the lower layer of the packaging unit 9 from being damaged by plane friction, and the strapping belt is not in contact with the inclined surface of the front flip frame 4. The upper finished corrugated paper box of the packing unit will be tightened due to the relative stillness to prevent the occurrence of strangulation marks and ensure the packing qualification rate of the packing unit 9. In the case of rolling friction, the instantaneous impact force generated when the packing unit 9 slides down is reduced. Although the final speed of the packing unit 9 may be faster (depending on the height and other factors), when reaching the end point, due to the existence of rolling friction, the speed of the packing unit 9 changes more slowly and will not stop suddenly like plane friction, thereby reducing the instantaneous impact force. A higher sliding speed means that the packing unit 9 has greater kinetic energy. However, due to the action of the support wheel 71, part of the kinetic energy will be used to maintain the rotational motion of the support wheel 71, rather than being completely converted into an impact on the end. Therefore, it can not only protect the packing unit 9 but also increase the packing speed.

[0037] Furthermore, the packaging unit 9 is composed of a plurality of groups of first corrugated cardboard boxes 91 and second corrugated cardboard boxes 92 that are stacked at intervals. The first corrugated cardboard boxes 91 and the second corrugated cardboard boxes 92 are provided with open ends and closed ends on all sides, and the open ends and the closed ends are arranged opposite to each other in pairs, and the open ends and the closed ends between adjacent first corrugated cardboard boxes 91 and second corrugated cardboard boxes 92 are staggered.

[0038] It should be noted that the structures of the first corrugated paper box 91 and the second corrugated paper box 92 are exactly the same. The first corrugated paper box 91 is taken as an example below. The cardboard of the first corrugated paper box 91 is composed of corrugated core paper and face paper. The first corrugated paper box 91 is a "mouth"-shaped component. The first corrugated paper box 91 is in a folded state, and the corrugated core paper and face paper can be clearly observed at the open ends at both ends, and the closed ends are closed connections. In order to make the thickness even when stacked, the first corrugated paper box 91 and the second corrugated paper box 92 are cross-stacked to form the packaging unit 9, that is, the two open ends of the first corrugated paper box 91 face left and right, and the open end of the second corrugated paper box 92 adjacent to it faces front and back.

[0039] Furthermore, the locking assembly includes a locking sleeve 75, one end of which is penetrated by a locking rod 751, one end of which is fixedly provided with an abutment block 752, and an air cavity 753 is opened inside the locking sleeve 75. Air is inflated into the air cavity 753 so that the locking rod 751 drives the abutment block 752 to abut the bottom of the wheel axle 74.

[0040] It should be noted that the abutment block 752 slides along the inside of the guide groove 731 , and the end of the locking rod 751 away from the abutment block 752 is provided with a piston sheet, and the piston sheet is slidably disposed inside the locking sleeve 75 .

[0041] Furthermore, a first hanging seat 14 is fixedly provided at one end of the main frame plate 11 close to the first fixed plate 12, a hanging plate 16 is installed on the first hanging seat 14, a connecting plate 72 is fixedly installed on the hanging plate 16, an installation cavity 721 is opened inside the connecting plate 72, the installation cavity 721 is connected to the air cavity 753, an elastic member 76 is fixedly provided at one end of the guide groove 731 away from the locking sleeve 75, and one end of the elastic member 76 is fixedly connected to the wheel axle 74.

[0042] When the front flip frame 4 is in the horizontal state, the support wheel 71 is located below the front flip frame 4, that is, the support wheel 71 does not contact the bottom surface of the packaging unit 9. When the front flip frame 4 rotates downward, the wheel axle 74 can be pressed down to make the wheel axle 74 contact with the abutment block 752, and drive the locking rod 751 to retract into the locking sleeve 75. When locking, an external air pump is connected through the installation cavity 721, or an air pump is installed inside the installation cavity 721, and the air cavity 753 is inflated by the air pump. The locking rod 751 is positioned by the blocking of the piston sheet at one end of the locking rod 751, so that the wheel axle 74 is supported by the abutment block 752, thereby achieving a positioning effect.

[0043] Furthermore, a resistance adjustment component is provided between the support wheel 71 and the axle 74, and the resistance adjustment component is used to adjust the contact resistance between the support wheel 71 and the axle 74. The resistance adjustment component includes a speed reduction block 741, and the speed reduction block 741 is detachably connected to the axle 74. A second friction pad 742 is provided on the outer periphery of the speed reduction block 741, and the cross-section of the second friction pad 742 is trapezoidal. The inner ring of the support wheel 71 is installed with a first friction pad 711.

[0044] It should be noted that the end with a smaller diameter of the second friction pad 742 is close to the inner ring of the rolling support mechanism 7. By pushing the deceleration block 741 toward the inner ring, the pressure between the first friction pad 711 and the second friction pad 742 is increased, thereby increasing the rotation resistance and slowing down the rotation of the support wheel 71, thereby preventing the packaging unit 9 from sliding down too fast and making virtual contact with the surface of the support wheel 71, which would affect the use effect of the support wheel 71.

[0045] Furthermore, a pin seat 743 is fixedly provided on one side of the speed reduction block 741 away from the support wheel 71 , a pin hole 744 is opened on the outer periphery of the wheel axle 74 , a pin is installed on the pin seat 743 , and the pin is threadedly connected to the pin hole 744 .

[0046] It should be noted that the pin holes 744 are arranged in several groups along the axial direction of the wheel axle 74 .

[0047] When the packing unit 9 is flipped from the front flip frame 4 to the rear flip frame 5, the bottom corners of the finished corrugated paper box on the upper layer are used as fulcrums. When the thickness of the packing unit 9 increases, the difficulty of flipping the packing unit 9 increases accordingly, resulting in damage or deformation of the bottom corners, making it difficult or even impossible to flip the packing unit. During the flipping process, the corners of the packing unit 9 are easily squeezed and damaged, thereby affecting the flipping and palletizing work.

[0048] Refer to the instruction manual Figures 8 to 12 In order to solve this problem, the following technical solution is also provided: a supporting mechanism 8 is provided on one side of the rolling support mechanism 7, the supporting mechanism 8 includes an intermediate seat 81, a bottom supporting seat 82 is movably provided above the intermediate seat 81, a second fixed plate 13 is installed at one end of the main frame plate 11 away from the first fixed plate 12, a rear flip frame 5 is rotatably installed on the second fixed plate 13, a second hanging seat 15 is installed at one end of the main frame plate 11 away from the first hanging seat 14, a vertical hanging frame 17 is installed on the second hanging seat 15, and a horizontal hanging frame 17 is installed on the vertical hanging frame 17 The mounting frame 18, a first rotation driver 181 and a support block 182 are installed at one end of the horizontal hanging frame 18, a connecting seat 83 is provided between the first rotation driver 181 and the support block 182, one end of the connecting seat 83 is connected to the first rotation driver 181 through an axial hole 833, the other end of the connecting seat 83 is connected to the support block 182 through a support column 832, the connecting seat 83 is fixedly connected to the intermediate seat 81, a notch 183 is provided at one end of the horizontal hanging frame 18, and the notch 183 is arranged corresponding to the connecting seat 83.

[0049] It should be noted that the first rotation driver 181 is a driving motor, which is used to drive the connecting seat 83 and the bottom bracket 82 to rotate, and the support block 182 and the support column 832 play the role of rotation support.

[0050] Furthermore, a swing mechanism 6 is installed on the main frame plate 11, and the swing mechanism 6 includes a swing plate 61, and the swing plate 61 is rotatably installed on the gantry 62, and the swing plate 61 is located above the front flip frame 4. A first linear drive 171 is installed on the vertical hanging frame 17, and a second linear drive 184 is installed between the vertical hanging frame 17 and the horizontal hanging frame 18. The first linear drive 171 is used to drive the horizontal hanging frame 18 to move vertically, and the second linear drive 184 is used to drive the horizontal hanging frame 18 to move horizontally.

[0051] It should be noted that the swing mechanism 6 adopts the existing technology mentioned in the background technology, and drives the swing plate 61 to rotate through the motor, thereby moving the top of the packaging unit 9 to flip, and the first linear drive 171 and the second linear drive 184 are linear guides or screw rods.

[0052] Furthermore, an exhaust seat 811 is installed on the middle seat 81, and a third linear drive 831 is installed on the connecting seat 83. The output shaft of the third linear drive 831 is fixedly connected to the bottom support seat 82. A buffer assembly 84 is installed on the bottom support seat 82, and several groups of buffer assemblies 84 are arranged corresponding to the first corrugated paper box 91. A cleaning gap 85 is provided between two adjacent groups of buffer assemblies 84, and the cleaning gap 85 corresponds to the exhaust port of the exhaust seat 811. The buffer assembly 84 includes a pad block 841, a buffer air cushion 842 is installed on the pad block 841, an abutment pad 843 is installed on the buffer air cushion 842, and an air guide groove 844 is provided on the top of the abutment pad 843.

[0053] It should be noted that the cross-section of the bottom support seat 82 is L-shaped, and the open side of the bottom support seat 82 faces the rear flip frame 5. The output shaft of the third linear drive 831 passes through the middle seat 81. A negative pressure pump is installed inside the vacuum seat 811 or the vacuum seat 811 is connected to a negative pressure pump, and a vacuum port is provided at one end of the vacuum seat 811.

[0054] In this embodiment, the implementation scenario is specifically as follows: before the packaging unit 9 slides down the inclined surface of the front flip frame 4, the connecting seat 83 pushes the bottom support seat 82 to rise, and the packaging unit 9 is supported by the bottom support seat 82. At this time, the buffer component 84 abuts against the first corrugated paper box 91. The buffer air cushion 842 and the abutment pad 843 are both made of elastic materials and play a buffering role. The air guide groove 844 plays a role in discharging the air under the closed end of the first corrugated paper box 91 to reduce air resistance. The debris inside the second corrugated paper box 92 falls into the cleaning gap 85 through the open end, and the debris is discharged from the exhaust port through the exhaust seat 811 to avoid injury caused by hard debris. The packaging unit 9, when the thickness of the packaging unit 9 increases, the first linear driver 171 drives the transverse lifting frame 18 to move vertically, and cooperates with the second linear driver 184 to drive the transverse lifting frame 18 to move horizontally, so as to adapt to the rotational movement of the bottom of the packaging unit 9. The first rotation driver 181 drives the supporting mechanism 8 to rotate, so that the bottom of the packaging unit 9 rotates, which is used to cooperate with the swing plate 61 to turn the top of the packaging unit 9. At this time, active flipping components are set on the top and bottom of the packaging unit 9 to reduce the difficulty of flipping the packaging unit 9. During the flipping process, it is not easy to squeeze and damage the corners of the packaging unit 9.
