[0025] Please refer to Figures 1 to 8 , a case packing machine with stability, including a workbench 10, a first conveying component 20 installed on the workbench 10 for conveying empty boxes, a second conveying component 30 for conveying objects to be packed in boxes, a storage component 30 for storing and placing objects to be packed in boxes, a first material transfer manipulator 40 for transferring the objects to be packed in boxes from the second conveying component 30 to the storage component 30, a second material transfer manipulator 50 for transferring the objects to be packed in boxes from the storage component 30 to the empty boxes on the first conveying component 20, and a third conveying component 60 installed on both sides of the first conveying component 20 for abutting against both sides of the empty boxes on the first conveying component 20 and driving the empty boxes to move along the conveying direction of the first conveying component 20.

[0026] During operation, the objects to be packed are conveyed by the second conveying component 30 and then transferred to the storage component 30 for transfer by the first manipulator component. At this time, the empty boxes are conveyed by the first conveying component 20. During the movement of the empty boxes along the first conveying component 20, the third conveying component 60 abuts against both sides of the empty boxes and synchronously drives the sides of the empty boxes to move along the transfer direction of the first conveying component 20, improving the stability of the transfer of the empty boxes while enhancing the efficiency of the transfer of the empty boxes. When the empty boxes are transferred to the preset position, the second material transfer manipulator 50 component transfers the objects to be packed in the storage component 30 into the empty boxes located on the first conveying component 20. At this time, since the third conveying component 60 abuts against both sides of the empty boxes, the stability of the empty boxes during packing is ensured. After packing is completed, the first conveying component 20 cooperates with the third conveying component 60 to convey the empty boxes to the next process.

[0027] Further, a spreading component 70 for spreading the opening of an empty box is provided above the first conveying component 20. In this embodiment, with the arrangement of the spreading component 70, it is convenient for the second material transfer manipulator 50 to transfer the objects to be packed from the storage component 30 into the empty box. Further, the spreading component 70 includes a horizontal cross frame 701 installed above the first conveying component 20, a first lifting cylinder 702 installed below the horizontal cross frame 701, a first moving plate 703 connected to the first lifting cylinder 702 and vertically moving relative to the horizontal cross frame 701 driven by the first lifting cylinder 702, a second lifting cylinder 704 installed on the first moving plate 703, a second moving plate 705 connected to the second lifting cylinder 704 and vertically lifting relative to the first moving plate 703 driven by the second lifting cylinder 704, a first square frame 706 installed on one side of the first moving plate 703, a second square frame 707 installed below the first square frame 706 and connected to one side of the second moving plate 705, a spreading plate 708 with its upper part rotatably installed on the side of the first square frame 706 and its inner side abutted against the inner side of the second square frame 707, and a connecting bar 709 installed on the side of the spreading plate 708 abutting against the second square frame 707; wherein, both ends of the connecting bar 709 are connected to the spreading plate 708 and form a through hole for the side part of the second square frame 707 to pass through; the size length of the second square frame 707 is smaller than that of the first square frame 706. Specifically, in this embodiment, when the empty box moves to the lower part of the first square frame 706 and the second square frame 707, at this time, the first lifting cylinder 702 works, and then drives the first moving plate 703 and the second moving plate 705 to move downward synchronously, so that the spreading plate 708 falls into the opening of the empty box. At this time, the second lifting cylinder 704 works, and then drives the second moving plate 705 to move downward relative to the first moving plate 703, thereby driving the second square frame 707 to move downward relative to the first square frame 706. Since the second square frame 707 is smaller than the first square frame 706, the second square frame 707 drives the spreading plate 708 to rotate outward relative to the side part of the first square frame 706 during the downward movement through the setting of the through hole, so as to spread the opening of the empty box, thus facilitating the second moving manipulator to stably perform the packing process. Specifically, the centers of the first square frame 706 and the second square frame 707 are on the same vertical axis, and the length and width of the second square frame 707 are both smaller than those of the first square frame 706.

[0028] A packing machine with stability according to the present invention, through the arrangements of the first conveying component 20, the second conveying component 30, the third conveying component 60, the first material transfer manipulator 40, the second material transfer manipulator 50 and the spreading component 70, has a high packing efficiency and can stably and efficiently transfer empty boxes, being suitable for industrial applications.

[0029] In a specific embodiment, the first conveying assembly 20 includes a first conveyor belt 201 for conveying empty boxes. Specifically, during operation, the empty boxes are placed on the first conveyor belt 201, and the first conveyor belt 201 rotates to convey the empty boxes to a preset position. Specifically, both ends of the first conveyor belt 201 are connected to a first drive shaft, and one end of one of the first drive shafts is connected to a first motor 202; during operation, the first motor 202 drives the first drive shaft connected thereto, and then cooperates with the other first drive shaft to drive the first conveyor belt 201 to rotate. The third conveying assembly 60 includes sliding platforms 601 installed on both sides of the first conveyor belt 201, a second conveyor belt 602 vertically installed above the sliding platforms 601, and a drive unit connected to the two sliding platforms 601 for driving the two sliding platforms 601 to approach or move away from each other. Specifically, during operation, the empty boxes are conveyed by the first conveyor belt 201. At this time, the second conveyor belt 602 is in a rotating working state, and has the same rotation frequency as the first conveyor belt 201 and the same conveying direction as the first conveyor belt 201. Then, the drive unit drives the two sliding platforms 601 to approach each other to contact the sides of the empty boxes, so that the first conveyor belt 201 and the second conveyor belt 602 cooperate to stably and efficiently convey the empty boxes to the packing station. During packing, the first conveyor belt 201 and the second conveyor belt 602 stop rotating. After packing is completed, the first conveyor belt 201 and the second conveyor belt continue to work together to convey the boxes after packing out; in this embodiment, through the coordinated work of the first conveyor belt 201 and the first and second conveyor belts 602, the packing process can be completed stably and efficiently. Specifically, in this embodiment, both ends of the second conveyor belt 602 are provided with second drive shafts 603, and one end of one of the second drive shafts 603 is connected to a second motor 604; during operation, the second motor 604 drives the second drive shaft 603 connected thereto to rotate, and then cooperates with the other second drive shaft 603 to drive the second conveyor belt 602 to rotate; further, during operation, the working frequencies of the first motor 202 and the second motor 604 are the same, so as to ensure the synchronous and orderly coordinated work of the first conveyor belt 201 and the second conveyor belt 602. The drive unit includes a slide rail 605, a transmission rod 606, a transmission lead screw 607, and a third motor 608; the slide rail 605 is installed below the sliding platform 601 and is slidably connected to the sliding platform 601 for allowing the sliding platform 601 to move towards the first conveyor belt 201; the transmission rod 606 is installed at the bottom of the sliding platform 601 and extends into the workbench 10; the transmission lead screw 607 is installed in the workbench 10 and is connected to the two transmission rods 606 for driving the two transmission rods 606 to approach or move away from each other when rotating; the third motor 608 is connected to the transmission lead screw 607 for driving the transmission lead screw 607 to rotate.Specifically, in this embodiment, the transmission lead screw 607 is provided with two opposite thread segments, and the bottoms of the two transmission rods 606 are respectively connected to the two opposite thread segments. The workbench 10 is provided with avoidance grooves for the movement of the transmission rods 606. During operation, the third motor 608 drives the transmission lead screw 607 to rotate. Due to the arrangement of the two opposite thread segments, when the transmission lead screw 607 rotates, the two transmission rods 606 are driven to approach or move away from each other as required, thereby driving the two sliding platforms 601 to approach or move away from the empty box as required to abut against the empty box. Anti-slip strips (not shown in the figure) are equidistantly arranged on the surface sides of the first conveyor belt 201 and the second conveyor belt. In this embodiment, through the arrangement of the anti-slip strips, the empty box is further stably driven to move.

[0030] In a specific embodiment, the storage assembly 30 includes a placing table 301 for placing the objects to be packed, a pressing plate 302 installed on the upper side of the placing table 301, and a pressing cylinder 303 connected to the pressing plate 302 for driving the pressing plate 302 to move on the placing table 301. Specifically, in this embodiment, a placing groove for loading the objects to be packed is provided above the placing table 301; the pressing plate 302 is located on one side of the placing groove. During operation, the objects are transferred from the first conveying assembly 20 to the placing groove by the first material transfer manipulator 40. At this time, the pressing cylinder 303 drives the pressing plate 302 to move and presses the objects to be packed and limits them in the placing groove.

[0031] In a specific embodiment, the first material transfer manipulator 40 includes a column 401 installed at the output end of the first conveying assembly 20, a first linear module 402 horizontally installed on the column 401, a second linear module 403 installed on the first linear module 402 and used to horizontally move under the drive of the first linear module 402, a rotating module installed on the second linear module 403 and used to vertically lift under the drive of the second linear module 403, and a grasping module connected to the rotating module and used to rotate under the drive of the rotating module. Specifically, in this embodiment, the first linear module 402 and the second linear module 403 are vertically arranged, which are used to drive the rotating module and the grasping module to move horizontally and vertically at the output end of the first conveying assembly 20. The rotating module is a rotating cylinder 404. The grasping module includes a connecting plate 405 connected to the rotating cylinder 404, and a plurality of vacuum suction cups 406 installed on the connecting plate 405 for sucking the objects to be packed. During operation, the vacuum suction cups 406 connected to the connecting plate 405 move multi-axially as required under the drive of the first linear module 402, the second linear module 403, and the rotating module, so as to transfer the objects to be packed from the first conveying assembly 20 to the storage assembly 30. Specifically, the second material transfer manipulator 50 is a palletizing manipulator.
