DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4 The present invention provides a technical solution: a fully automatic stacking device for packaging boxes, comprising a base 1, a vertical frame 2 is slidably connected to the top of the base 1, a horizontal frame 3 is slidably connected to the front of the vertical frame 2, a moving block 4 is slidably connected to the bottom of the horizontal frame 3, a clamping assembly 5 is arranged at the bottom of the moving block 4, the clamping assembly 5 comprises a sleeve 51 fixedly connected to the bottom surface of the moving block 4, a through-tube 52 is slidably connected to the inner wall of the sleeve 51, a crossbar 53 is fixedly connected to the bottom of the through-tube 52, and both sides of the crossbar 53 are Both are rotatably connected with a bending frame 54, and the sides of the two bending frames 54 that are close to each other at the bottom are fixedly connected with a clamping block 55, and the top of the bending frame 54 is fixedly connected with a counterweight block 56, and both sides of the sleeve 51 are fixedly connected with small plates 57, and a flexible steel wire rope 58 is fixedly connected between the bottom of the small plate 57 and the bending frame 54, and both sides of the sleeve 51 are provided with sliding grooves 59, and the insides of the two sliding grooves 59 are slidably connected with small rods 510, and the sides of the two small rods 510 that are close to each other are fixedly connected to the through pipe 52.

[0022] By adopting the above technical solution, driving components are arranged at the base 1, the vertical frame 2 and the horizontal frame 3, and the driving components include a motor and a screw rod. By driving the screw rod to rotate by the motor, the vertical frame 2 can be controlled to slide along the base 1, the horizontal frame 3 can be controlled to slide along the vertical frame 2, and the moving block 4 can be controlled to slide along the horizontal frame 3, so as to adjust the position of the clamping component 5. After the clamping component 5 clamps the packaging box, the packaging box can be transported to a suitable position for stacking. The method of driving the screw rod to drive the movement by the motor is a mature existing technology, so it will not be elaborated in detail.

[0023] When the packaging boxes need to be stacked, the packaging boxes need to be clamped first. During the clamping process, the clamping assembly 5 is adjusted to the top of the packaging boxes through the action of the driving assembly, and then the horizontal frame 3, the moving block 4 and the clamping assembly 5 are controlled by the driving assembly to move downward, so that the bottom of the bending frame 54 and the clamping block 55 are located on both sides of the packaging boxes, and then the moving block 4 and the clamping assembly 5 are controlled to move upward. During this process, under the action of the gravity of the cross bar 53, the sleeve 51 and the through tube 52 slide relative to each other, so that the small rod 510 By sliding inside the slide groove 59, due to the relative sliding of the sleeve 51 and the through tube 52, part of the small plate 57 can be moved away from the cross bar 53 and the bent frame 54, so that the flexible steel wire rope 58 is in a taut state, and the two bent frames 54 are rotated, so that the two clamping blocks 55 are brought closer to each other, thereby clamping the packaging box, and the clamping assembly 5 and the packaging box are moved to a suitable position by the vertical frame 2 sliding along the base 1, the horizontal frame 3 sliding along the vertical frame 2, and the moving block 4 sliding along the horizontal frame 3, and the packaging boxes are stacked.

[0024] It should be noted that, under the action of gravity of the packaging box and the products inside, the flexible steel wire rope 58 can be kept in a taut state, which is beneficial to increase the clamping force of the two bent frames 54, thereby ensuring the stability of the clamping. Such a design eliminates the need for electric or pneumatic clamping, reducing energy loss, while ensuring that the clamping force is sufficient to ensure the stability of the clamping.

[0025] Specifically, Figures 1 to 4 As shown, the two clamping blocks 55 are arranged at an angle on the sides close to each other.

[0026] By adopting the above technical solution, the packaging box clamped by the device is a packaging box made of plastic material, and the plastic material can undergo a small deformation, thereby avoiding hard damage to the packaging box.

[0027] When clamping, due to the inclination of the clamping block 55, the clamping block 55 is narrow at the top and wide at the bottom. When clamping, the bottom of the clamping block 55 is in a horizontal state. The narrow at the top and wide at the bottom slope helps to further improve the stability of clamping. At the same time, when the bending frame 54 rotates and moves the clamping block 55 for clamping, if the side of the clamping block 55 that is close to each other is not inclined, the top corner of the clamping block 55 will contact the packaging box first, which may cause the packaging box to deform excessively and be damaged.

[0028] Specifically, Figures 3 to 5 As shown, the rear of the sleeve 51 and the cross bar 53 are jointly provided with a locking assembly 6, and the locking assembly 6 includes a top plate 61 fixedly connected to the rear end of the sleeve 51, a vertical rod 62 is fixedly connected to the bottom of the top plate 61, a top cover 63 is fixedly connected to the bottom of the vertical rod 62, a circular plate 64 is slidably connected to the inside of the top cover 63, a spring 65 is fixedly connected between the top of the circular plate 64 and the inside of the top cover 63, an insertion rod 66 is rotatably connected to the bottom of the circular plate 64, and the locking assembly 6 also includes a bottom plate 67 fixedly connected to the rear of the cross bar 53, and the bottom of the bottom plate 67 is A small frame 68 is fixedly connected, a transverse groove 69 is provided on the rear end surface of the bottom plate 67, a bottom cover 611 is provided at the bottom of the top cover 63, a connecting frame 610 is fixedly connected between the top cover 63 and the bottom cover 611, an oblique groove 614 is provided on the side where the bottom cover 611 and the top cover 63 are close to each other, the oblique groove 614 on the bottom cover 611 and the oblique groove 614 on the top cover 63 are staggered, the bottom of the insertion rod 66 passes through the bottom cover 611 and is fixedly connected to a limiting plate 612, and the outer wall of the insertion rod 66 is located between the bottom cover 611 and the top cover 63 and is fixedly connected to a round rod 613.

[0029] By adopting the above technical solution, the connecting frame 610 is used to fix the top cover 63 and the bottom cover 611. In the initial state, the limiting plate 612 is perpendicular to the transverse groove 69, so that the limiting plate 612 will not pass through the transverse groove 69. At this time, it can play a role in limiting the cross bar 53 to prevent the cross bar 53 from sliding relative to the sleeve 51 due to gravity. At this time, under the action of the gravity of the counterweight block 56, the bottoms of the two bent frames 54 are separated from each other, which is convenient for subsequent clamping. The clamping blocks 55 are located on both sides of the packaging box. When clamping the packaging box, as the cross frame 3 and the moving block 4 move downward, the bottom of the cross bar 53 contacts the packaging box, so that the cross bar 53 is close to the small plate 57. During this process, the part of the vertical rod 62 of the top plate 61 moves relative to the bottom plate 67, and the bottom of the limiting plate 612 contacts the inner side of the small frame 68, so that the round rod 613 inside the inclined groove 614 in the bottom cover 611 reaches the round rod 613 on the top cover 63 The inclined groove 614 is located at the bottom cover 611. During this process, due to the inclination of the inclined groove 614, the insertion rod 66 is easy to rotate. Subsequently, when the cross frame 3 and the moving block 4 move upward, under the elastic force of the spring 65, the circular plate 64 and the insertion rod 66 are reset, so that the round rod 613 returns to the inclined groove 614 in the bottom cover 611. During this process, the round rod 613 uses the inclined setting inside the inclined groove 614 to rotate the insertion rod 66. In the above operation, the insertion rod 66 rotates 90 degrees, so that the limiting plate 612 is parallel to the cross groove 69, so that the limiting plate 612 will pass through the cross groove 69. At this time, the cross frame 3 and the moving block 4 continue to move upward. Under the action of the partial gravity of the cross bar 53, the sleeve 51 and the through tube 52 slide relative to each other, so that the flexible steel wire rope 58 is in a taut state, so that the two bent frames 54 rotate, and then the two clamping blocks 55 are close to each other, thereby clamping the packaging box.

[0030] When the packaging box is moved to the stacking position, the packaging box is placed at the designated position, and the horizontal frame 3 and the moving block 4 are continuously moved downward. In this process, the bottom of the limiting plate 612 contacts the inner side of the small frame 68, and the insertion rod 66 moves relative to the top plate 61, so that the round rod 613 inside the inclined groove 614 in the bottom cover 611 reaches the inclined groove 614 on the top cover 63. In this process, due to the inclination of the inclined groove 614, it is convenient for the insertion rod 66 to rotate. Then, when the horizontal frame 3 and the moving block 4 move upward, the elastic force of the spring 65 causes the round plate 64 and the insertion rod 66 to rotate. 6 is reset so that the round rod 613 returns to the inclined groove 614 in the bottom cover 611. During this process, the round rod 613 uses the inclined setting inside the inclined groove 614 to rotate the insertion rod 66. In the above operation, the insertion rod 66 rotates 90 degrees to make the limiting plate 612 perpendicular to the transverse groove 69. At this time, the limiting plate 612 will not pass through the transverse groove 69, which can limit the cross bar 53 and prevent the cross bar 53 from sliding relative to the sleeve 51 due to gravity. At this time, under the action of the gravity of the counterweight block 56, the bottoms of the two bent frames 54 are moved away from each other, making it easier to clamp later.

[0031] Such a design can conveniently control the bottom of the bending frame 54 to be in an open state or a clamping state, thereby making clamping more convenient during stacking and palletizing.

[0032] Specifically, Figures 3 to 6 As shown, a stabilizing clamping assembly 7 is arranged below the small rod 510, and the stabilizing clamping assembly 7 includes small blocks 71 fixedly connected to the bottom of both sides of the outer wall of the sleeve 51, and the top of the small block 71 is fixedly connected to an airbag 72, and the bottom of the airbag 72 is fixedly inserted with a pipe 73, the bottom of the bent frame 54 and the interior of the clamping block 55 are both hollow, and the hollow parts inside the bent frame 54 and the clamping block 55 are connected, and the end of the pipe 73 away from the airbag 72 is inserted into the hollow part inside the bent frame 54, and a groove 74 is opened on the side where the two clamping blocks 55 are close to each other, and a flexible rubber pad 75 is fixedly connected inside the groove 74, and the airbag 72 is made of a corrugated capsule body, and the part of the pipe 73 close to the bent frame 54 is made of hose material.

[0033] By adopting the above technical scheme, the small block 71 is designed to install the airbag 72, and the counterweight block 56 and the cross bar 53 are both made of metal materials with high density. When clamping, as the clamping assembly 5 is lowered as a whole, when the bottom of the cross bar 53 is limited by the packaging box, the small plate 57 is close to the cross bar 53, and the small rod 510 is away from the airbag 72. The airbag 72 expands due to its own elastic force. During the clamping process, due to the action of the cross bar 53's own gravity, the small plate 57 is away from the cross bar 53, so that the small rod 510 squeezes the airbag 72, and the gas inside the airbag 72 enters the interior of the pipe 73, and then enters the hollow space inside the bent frame 54 and the clamping block 55. At this time, under the action of the gas pressure, the gas applies pressure to the flexible rubber pad 75 at the empty groove 74, so that the flexible rubber pad 75 transfers the pressure to the clamped packaging box, further improving the stability of the packaging box when clamped.

[0034] Specifically, Figures 3 to 5 and Figure 7 As shown, an auxiliary component 8 is commonly provided inside and below the sleeve 51, and the auxiliary component 8 includes a long rod 81 fixedly connected to the top of the inner wall of the sleeve 51, and a piston 82 is fixedly connected to the lower end of the long rod 81. The auxiliary component 8 also includes a groove 83 opened in the middle part of the cross bar 53, and the bottom of the through-tube 52 is inserted into the groove 83. A small tube 84 is fixedly inserted at the bottom of the middle part of the cross bar 53, and an adsorption cover 85 is fixedly inserted at the bottom of the small tube 84. The adsorption cover 85 has a plurality of adsorption holes 89 at the bottom, and a ventilation pipe 86 is fixedly inserted at the bottom of the outer wall of the through-tube 52. A solenoid valve 87 is fixedly installed inside the ventilation pipe 86. The outer wall of the piston 82 fits with the inner wall of the through-tube 52, and the bottom of the adsorption cover 85 is located on the outside of the adsorption hole 89 and is fixedly connected with a rubber ring 88.

[0035] By adopting the above technical solution, when clamping, as the clamping assembly 5 is lowered as a whole, when the adsorption cover 85 at the bottom of the cross bar 53 is limited by the packaging box, the bottom of the rubber ring 88 fits tightly against the top of the packaging box, the solenoid valve 87 is closed, and at this time the piston 82 is located at the bottom position of the inner side of the through tube 52. During the clamping process, as the gravity of the cross bar 53 acts, relative displacement occurs between the cross bar 53, the long rod 81 and the piston 82. Since the bottom of the rubber ring 88 fits against the packaging box, negative pressure is generated inside the through tube 52. Since the inside of the through tube 52 is connected with the groove 83, the small tube 84 and the adsorption cover 85, negative pressure is generated inside the adsorption cover 85, and the top can be adsorbed through the adsorption hole 89, which can enhance the clamping stability to a certain extent.

[0036] When contact adsorption is required, the electromagnetic valve 87 installed on the vent pipe 86 is controlled to open so as to release the negative pressure.

[0037] It should be noted that when the cross bar 53 is limited, the bottoms of the two bent frames 54 are moved away from each other under the gravity of the counterweight 56 ​​. At this time, the solenoid valve 87 is opened to facilitate the gas to enter the interior of the through tube 52 .

[0038] Working principle: adjust the clamping assembly 5 to the top of the packaging box, then control the horizontal frame 3, the moving block 4 and the clamping assembly 5 to move downward through the driving assembly, so that the bottom of the curved frame 54 and the clamping blocks 55 are located on both sides of the packaging box, and then control the moving block 4 and the clamping assembly 5 to move upward. During this process, under the action of the gravity of the cross bar 53, the sleeve 51 and the through tube 52 slide relative to each other, so that the small rod 510 slides inside the slide groove 59. Due to the relative sliding of the sleeve 51 and the through tube 52, part of the small plate 57 can be moved away from the cross bar 53 and the curved frame 54, so that the flexible steel wire rope 58 is in a taut state, so that the two curved frames 54 rotate, and then the two clamping blocks 55 are close to each other, so as to clamp the packaging box, and the vertical frame 2 slides along the base 1, the horizontal frame 3 slides along the vertical frame 2, and the moving block 4 slides along the horizontal frame 3 to move the clamping assembly 5 and the packaging box to a suitable position, and the packaging boxes are stacked.

[0039] When clamping, due to the inclination of the clamping block 55, the clamping block 55 is narrow at the top and wide at the bottom. When clamping, the bottom of the clamping block 55 is in a horizontal state. The narrow at the top and wide at the bottom slope helps to further improve the stability of clamping. At the same time, when the bending frame 54 rotates and moves the clamping block 55 for clamping, if the side of the clamping block 55 that is close to each other is not inclined, the top corner of the clamping block 55 will contact the packaging box first, which may cause the packaging box to deform excessively and be damaged.

[0040] During clamping, as the clamping assembly 5 is lowered as a whole, when the bottom of the cross bar 53 is limited by the packaging box, the small plate 57 is close to the cross bar 53, and the small rod 510 is away from the airbag 72. The airbag 72 expands due to its own elastic force. During the clamping process, due to the gravity of the cross bar 53, the small plate 57 is away from the cross bar 53, so that the small rod 510 squeezes the airbag 72, and the gas inside the airbag 72 enters the inside of the pipe 73, and then enters the hollow inside the bent frame 54 and the clamping block 55. At this time, under the action of the gas pressure, the gas applies pressure to the flexible part at the empty groove 74. The rubber pad 75 allows the flexible rubber pad 75 to transfer pressure to the clamped packaging box, further improving the stability of the packaging box when clamped. During the clamping process, with the action of the gravity of the cross bar 53, relative displacement occurs between the cross bar 53, the long rod 81 and the piston 82, and since the bottom of the rubber ring 88 fits the packaging box, negative pressure is generated inside the through tube 52. Since the inside of the through tube 52 is connected with the groove 83, the small tube 84 and the inside of the adsorption cover 85, negative pressure is generated inside the adsorption cover 85, and the top can be adsorbed through the adsorption hole 89, which can enhance the clamping stability to a certain extent.
