Description

Technical Field

[0001] The invention relates to a box packing device, in particular to a box body automatic overturning box packing device suitable for a production line, belonging to the technical field of packaging machinery and equipment. Background Art

[0002] Traditional object packaging and boxing operations are mostly done manually, which is labor-intensive, inefficient and prone to errors. With the rapid development of the logistics industry, the demand for automatic object boxing is becoming increasingly urgent, and the quality and efficiency requirements are becoming higher and higher.

[0003] A search shows that a Chinese patent with application number CN201811088799.9 discloses a multi-box packing gripper robot. When multiple boxes are stacked and sorted into N rows arranged from top to bottom and moved into position, the packing gripper is in place, centered in place, and then drops to be flush with the top end face of the N rows of boxes. The fixed splint and the movable splint first clamp the two side faces of all the boxes, and the two side splints clamp the other two side faces of all the boxes. The robot drives the packing gripper and all the boxes to move to the packing position. When the lifting cylinder drives the bottom of all the boxes to be flush with the carton folding line, the gripper splint cylinder is depressurized, and the lifting cylinder continues to drive all the boxes to descend. When the boxes are dropped into place, the side splints are depressurized, and the packing gripper rises to leave the packing opening device and resets for the next round of grabbing. However, in order to complete complex packing operations such as stacking and flipping multiple boxes, this technical solution must be equipped with a six-axis robot. Not only is the equipment cost and maintenance threshold high, but when it is matched with the production line, the robot occupies the space outside the line, which is very inconvenient and difficult to promote. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic box turning and packing device which can reliably complete a series of actions such as automatic box alignment, turning and packing through a planar mechanical structure, and has a compact structure and is easy to match with a production line.

[0005] In order to achieve the above-mentioned purpose, the basic technical scheme of the box body automatic flipping packing equipment of the present invention is as follows: it comprises a frame whose lower part passes through a conveying roller, the front and rear sides of the frame along the conveying direction are respectively provided with front and rear guide beams of a propulsion alignment mechanism forming a horizontal moving pair, and are respectively fixed with front and rear horizontal cylinders and guide columns of a lifting mechanism and a guide column of a flipping mechanism; the guide columns support a clamping mechanism; a receiving surface is provided on the frame below the clamping mechanism;

[0006] The inner ends of the front and rear guide beams are respectively fixedly connected to the front and rear propulsion plates, and the front and rear propulsion plates are respectively fixedly connected to the telescopic ends of the front and rear horizontal cylinders;

[0007] The guide column and the flip seat of the clamping mechanism form a vertical moving pair, the flip seat is connected to a vertical screw rod, and the screw rod and a nut axially constrained on the frame form a spiral pair;

[0008] The flip seat is hinged with a guide rod vertically connected to the horizontal axis through a horizontal axis, and the horizontal axis is equipped with an upper pull cylinder and a lower pull cylinder through a connecting block. The upper end and the lower end of the guide rod respectively form a moving pair with the upper clamping plate and the lower clamping plate; the telescopic ends of the upper pull cylinder and the lower pull cylinder are respectively connected to the upper clamping plate and the lower clamping plate;

[0009] The outer end of the horizontal shaft is provided with a driven sprocket, which is supported on a lifting slider that forms a moving pair with the guide column, and is connected to a driving sprocket supported on a lifting rod through a chain transmission, and the lower end of the lifting rod is fixedly connected to the lifting slider;

[0010] The receiving surface is composed of four receiving plates which are hingedly mounted on the frame and can be turned over and opened.

[0011] Compared with the prior art, the present invention integrates box sorting, turning and packing, realizes automatic packing on the production line, significantly improves production efficiency and reduces labor costs; and has a compact structure and can be directly combined with a conveyor line, with a small footprint and low maintenance costs.

[0012] A further improvement of the present invention is that the guide post of the flipping mechanism and the guide post of the lifting mechanism share the same component.

[0013] A further improvement of the present invention is that the receiving surface is composed of four receiving plates which are hingedly mounted on the front, rear, left and right of the frame and can be flipped and opened.

[0014] A further improvement of the present invention is that a lower slide plate with a slide groove extends from the lower surface of the hinged end of the receiving plate, a rotary cylinder is installed near the hinged end of the frame, and the sliding pin at the outer end of the rotating arm of the rotary cylinder and the slide groove on the lower slide plate form a moving pair.

[0026] The technical solutions in the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] The box body automatic flipping and packing equipment of this embodiment is as follows Figure 1 , Figure 2 and Figure 3 As shown, it includes a frame 4, a pushing and aligning mechanism 5, a clamping mechanism 6, a lifting mechanism 7, a turning mechanism 8 and a receiving surface.

[0028] The lower part of the frame 4 passes through the conveying roller 2. The front and rear sides of the frame 4 along the conveying direction are respectively equipped with front and rear guide beams 502, 502' of the propulsion alignment mechanism 5 which form a horizontal moving pair through a sliding sleeve, and are respectively fixed with front and rear horizontal cylinders 503, 503' and guide columns 702 of the lifting mechanism 7 (see Figure 6 ), the guide post 804 of the flipping mechanism 8 (the optimal design of this embodiment is that the guide post 804 of the flipping mechanism 8 and the guide post 702 of the lifting mechanism 7 share one guide post). The guide post 702 supports the clamping mechanism 6, and a receiving surface is installed on the frame 4 below the clamping mechanism 6.

[0029] See also Figure 7The inner ends of the front and rear guide beams 502 and 502' are respectively fixedly connected to the front and rear propulsion plates 501 and 501', and the front and rear propulsion plates 501 and 501' are respectively fixedly connected to the telescopic ends of the front and rear horizontal cylinders 503 and 503', so that under the drive of these two cylinders, the box body 10 can be pushed together in the horizontal direction.

[0030] See also Figure 6 The guide column 702 of the lifting mechanism 7 and the flip seat 602 of the clamping mechanism 6 form a vertical moving pair, the flip seat 602 is connected to the screw 703, and the screw 703 and the nut 704 driven by the motor 701 axially constrained to the frame 4 form a spiral pair, so the motor 701 can drive the flip seat 602 to move up and down along the guide column 702 through the screw nut mechanism.

[0031] See also Figure 5 and Figure 8 The flip seat 602 is hinged with a guide rod 604 vertically fixed to the horizontal axis through a horizontal axis 607, and the horizontal axis 607 is equipped with an upper pull cylinder 601 and a lower pull cylinder 603 through connecting blocks on both sides, and the upper end and the lower end of the guide rod 604 respectively form a moving pair with the upper clamping plate 605 and the lower clamping plate 606; the telescopic ends of the upper pull cylinder 601 and the lower pull cylinder 603 are respectively connected to the upper clamping plate 605 and the lower clamping plate 606; therefore, the telescopic movement of the upper pull cylinder 601 and the lower pull cylinder 603 can respectively drive the upper clamping plate 605 and the lower clamping plate 606 to clamp the box body, and the rotation of the horizontal axis 607 can drive the clamping mechanism 6 including the upper pull cylinder 601, the lower pull cylinder 603, the upper clamping plate 605 and the lower clamping plate 606 to flip.

[0032] See also Figure 4 A driven sprocket 805 is installed at the outer end of the horizontal shaft 607, and the driven sprocket 805 is supported on a lifting slider 806 that forms a moving pair with the guide column 804, and is connected to the driving sprocket 802 driven by the motor 801 supported on the lifting rod 807 through a chain 803 transmission, and the lower end of the lifting rod 807 is fixedly connected to the lifting slider 806; therefore, when the horizontal shaft 607 moves up and down with the clamping mechanism 6, it does not interfere with the flipping movement of the clamping mechanism 6 driven by the motor 801 driving the horizontal shaft 607 to rotate through the chain transmission.

[0033] like Fig. 9 , Fig.10 As shown, the receiving surface is composed of four receiving plates 9 that are hinged to the front, back, left, and right sides of the frame 4 and can be flipped open. A lower slide plate 9-1 with a slide groove extends from the lower surface of the hinged end of the receiving plate 9. A rotary cylinder 9-3 is installed near the hinged end of the frame 4. The sliding pin 9-2 at the outer end of the rotating arm of the rotary cylinder 9-3 and the slide groove on the lower slide plate 9-1 form a moving pair. Therefore, when the rotary cylinder 9-3 drives the rotating arm to swing, the closing of the receiving plate 9 can be achieved through the action of the sliding pin on the slide groove ( Fig. 9 ) and turn on ( Fig.10 ), when lifted up and closed, a receiving surface is formed, and when flipped down and opened, the receiving plate 9 opens the upper opening of the box body 3 and becomes a guide plate, so that the box body 10 on the receiving plate 9 falls into the box body 3 on the conveying roller 2 under the guidance of the opened receiving plate 9.

[0034] The working process of the box body automatic flipping and packing device in this embodiment is as follows: Figures 11 to 20 As shown:

[0035] Fig.11 ——The box body 10 to be packed is placed on the receiving surface;

[0036] Fig.12 - The front and rear horizontal cylinders 503 and 503' of the push alignment mechanism 5 move toward the box body 10 from the left and right sides of the box body, so that the box bodies 10 are aligned in one direction and stacked close to each other in an orderly manner;

[0037] Fig.13 ——After the box bodies 10 are neatly stacked, the front and rear horizontal cylinders 503, 503' leave the box bodies 10 and return to their original positions;

[0038] Fig.14 - The pull-up cylinder 601 and the pull-down cylinder 603 of the clamping mechanism 6 approach the box body 10 from both the upper and lower directions until the box body 10 is clamped;

[0039] Fig.15 ——The screw nut mechanism of the lifting mechanism 7 drives the flip seat 602 to rise along the guide column 702, so that the clamping mechanism 6 and the flip mechanism 8 together with the box body 10 are lifted as a whole;

[0040] Fig.16 ——The turning mechanism 8 drives the clamping mechanism 6 to turn 90° through the chain transmission, and the box body 10 as a whole also turns 90°;

[0041] Fig.17 ——The rotary cylinder 9-3 drives the receiving plate 9 of the receiving surface to open, and each receiving plate 9 turns downward to prop up the opening of the box body 3 and form a guide;

[0042] Fig.18 ——The lifting mechanism 7 drives the clamping mechanism 6 to descend, so that the box body 10 as a whole enters the opening of the box body 3;

[0043] Fig.19 ——The clamping mechanism 6 releases the box body 10, and the box body 10 completely falls into the box body 3;

[0044] Fig. 20 ——After packing is completed, each mechanism returns to its initial state in turn, ready for the next box packing operation.

[0045] Tests have shown that the automatic box-turning and packing device of this embodiment can be used for automatic packing of boxes of various specifications, with high efficiency, good quality, safety and reliability.

[0046] The above embodiments describe only a part of the embodiments of the present invention, rather than all the embodiments.
