[0036] The present invention will be described clearly and completely below with reference to the embodiments.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0039] See attached Figure 1-12, shown is a vertical case packing machine, including a frame 1, in which a first conveying unit 3, a second conveying unit 4, and a third conveying unit 5 are arranged from left to right. A horizontal beam 2 is provided on the top of the frame 1, and a grabbing unit 7 is slidably provided on the beam 2. An opening unit 6 is provided on the beam 2 above the second conveying unit 4, and a pushing unit 9 is slidably provided on the other side of the beam 2. A feeding unit 8 is provided on the right side of the third conveying unit 5 in the frame 1;

[0040] Specifically, the first conveying unit 3 includes a first conveying frame 11, on which a plurality of conveying rollers 12 are rotatably provided, and a first pushing mechanism is provided on the first conveying frame 11, which includes a first driving cylinder 13. The first driving cylinder 13 is arranged at the inner bottom of the first conveying frame 11 and near the middle position, and an output end of the first driving cylinder 13 is provided with two support rods 14, and a mounting plate 15 is arranged on the top of the two support rods 14. A compensation driving cylinder 16 is provided on the mounting plate 15, and a first pushing plate 17 is provided at the output end of the compensation driving cylinder 16. When in use, the packaging box 64 passes through the conveying rollers 12 to reach the position of the first pushing plate 17, and then the first pushing plate 17 moves in a direction perpendicular to the moving direction of the packaging box 64 on the conveying rollers 12 under the action of the first driving cylinder 13, and pushes the packaging box 64 to the second conveying unit 4. Due to the structural width limitation of the first conveying frame 11 itself, the stroke of the first driving cylinder 13 is further compensated by the compensation driving cylinder 16 to push the packaging box 64 to the second conveying unit 4;

[0041] The second conveying unit 4 includes a second conveying frame 18, and the second conveying frame 18 is provided with a feed port 19 directly opposite the first push plate 17. When in use, when the first push plate 17 pushes the packaging box 64 to the second conveying unit 4, the packaging box 64 enters the second conveying frame 18 from the feed port 19. The second conveying frame 18 is provided with a second pushing mechanism at one end close to the feed port 19. The second pushing mechanism includes a second driving cylinder 21 provided at the bottom of the second conveying frame 18, and a first bracket 22 is provided at the output end of the second driving cylinder 21. The first bracket 22 is installed There is an adjustment frame 23, on which a second push plate 25 is provided, wherein the movement direction of the second push plate 25 is perpendicular to that of the first push plate 17, and the second conveying frame 18 is located at one end of the opening unit 6 and is provided with a third pushing mechanism, the third pushing mechanism includes a third driving cylinder 26, and the output end of the third driving cylinder 26 is provided with a second bracket 27, and a third push plate 28 is provided on the second bracket 27, and the movement direction of the third push plate 28 is the same as that of the first push plate 17 and is perpendicular to the second push plate 25, and the second conveying frame 18 is located directly opposite the third push plate 28 and is provided with a discharge port 20;

[0042] The third conveying unit 5 includes a third conveying frame 29 and a conveyor belt 30, wherein the conveyor belt 30 is flush with the discharge port 20 to facilitate the smooth transfer of the packaging box 64. When in use, after the packaging box 64 is pushed onto the second conveying frame 18 by the first push plate 17, the packaging box 64 is then pushed to the opening unit 6 by the second push plate 25 for packing. After the packing is completed, it is pushed onto the conveyor belt 30 of the third conveying unit 5 by the third push plate 28.

[0043] It can be seen that the present invention changes the layout of the first conveying unit 3, the second conveying unit 4 and the third conveying unit 5 in the frame 1, so that the volume of the entire case packing machine is smaller and the structure is more compact than when the case packing machine is arranged linearly, which greatly reduces the floor space occupied by the entire case packing machine in the workshop, so that the case packing machine can be used in a workshop with limited space without expanding the workshop, thereby reducing the production cost of the enterprise;

[0044] Furthermore, the opening unit 6 includes a connecting column 31 connected to the crossbeam 2, one end of the connecting column 31 is bolted to a guide seat 32, both ends of the guide seat 32 are provided with a guide rod 33, one end of the guide rod 33 is connected to a support arm 34, and a screw 35 is provided in the middle of the guide seat 32, one end of the screw 35 is rotatably connected to the support arm 34, when in use, the screw 35 cooperates with the guide rod 33 to enable the support arm 34 to be adjusted in height, thereby being able to adapt to packaging boxes 64 of different heights, and mounting seats 36 are symmetrically provided at both ends of the support arm 34, for installation. An open cylinder 37 is provided at one end of the seat 36, and a lever 38 is clamped at the output end of the open cylinder 37. One end of the lever 38 is rotatably mounted on the mounting seat 36, and a dial plate 39 is provided on the lever 38. When the packing box 64 is pushed between the two levers 38 by the second push plate 25 during use, the open cylinder 37 drives the levers 38 to rotate in opposite arcs. The lever 38 further uses the dial plate 39 to flip the folded pages of the packing box 64 outward, thereby increasing the opening area of the end of the packing box 64, avoiding the folding and closing during packing, and facilitating packing.

[0045] Furthermore, the grabbing unit 7 includes a robotic arm 40 and a negative pressure fan 10 arranged on the top of the frame 1. A rotary sleeve 43 is provided at the top of the robotic arm 40. The rotary sleeve 43 is connected to the negative pressure fan 10 pipeline. The other end of the rotary sleeve 43 is connected to a negative pressure pipe 44. The negative pressure pipe 44 is built into the robotic arm 40. The rotary sleeve 43 not only realizes the connection between the negative pressure pipe 44 and the negative pressure fan 10, but also avoids the twisting and knotting of the pipeline between the rotary sleeve 43 and the negative pressure fan 10. A sponge suction cup 41 is provided at the other end of the robotic arm 40, and is equipped with a control valve 42. When in use, the negative pressure fan 10 provides negative pressure to the sponge suction cup 41 to achieve the adsorption and grabbing of the ice cream. At the same time, a first driving mechanism is provided on the robotic arm 40.

[0046] The first driving mechanism includes a first slide rail 47 arranged transversely on the crossbeam 2 and driving wheels 45 located at both ends of the crossbeam 2, each driving wheel 45 is equipped with a first driving motor 46, and a slide plate 48 is slidably provided on the first slide rail 47. The robot arm 40 can slide vertically on the slide plate 48. The slide plate 48 is located on both sides of the robot arm 40 and is provided with two first guide wheels 49, and a second guide wheel 50 is provided at the top of the robot arm 40. When in use, a synchronous belt is wound between the two driving wheels 45, the first guide wheel 49 and the second guide wheel 50. The two ends of the synchronous belt are respectively fixed to the two sides of the robot arm 40. The synchronous belt is driven by the two first driving motors 46 to realize the horizontal and vertical sliding of the entire robot arm 40 on the crossbeam 2. It should be noted that the winding method of the synchronous belt has been disclosed in the patent with the announcement number CN 108341091 B, and therefore will not be described in detail.

[0047] Furthermore, the feeding unit 8 includes a feeding mechanism, a receiving mechanism and a swinging mechanism. The feeding mechanism includes a feeding trough 51, a feeding belt is provided in the feeding trough 51, and a feeding motor 52 is provided on the feeding belt. The feeding mechanism includes a receiving frame, and two feeding belts 53 are provided on the feeding frame. Connecting seats 54 are equidistantly provided on the feeding belts 53, and baffles are bolted to the connecting seats 54. Each feeding belt 53 is separately equipped with a feeding motor, and all are uniformly controlled by a controller 63. The feeding trough 51 is tilted to one side of the feeding belt 53. When in use, the ice cream is tilted and placed on the feeding belt, and is driven by the feeding motor 52 to reach the baffle. Then, under the action of the baffle, the ice cream changes from an oblique direction to a vertical direction and is transported to the swinging mechanism.

[0048] It should be noted that the two receiving belts 53 operate alternately. When the receiving belt 53 close to the swing mechanism is in use, the baffle on the other receiving belt 53 is tilted at the same angle as the ice cream and is fixed. At this time, the baffle acts as a transition, guiding the ice cream to the other baffle. When the ice cream reaches the other baffle, it is driven by the receiving motor to be transported to the swing mechanism.

[0049] Furthermore, the pushing unit 9 includes a downward cylinder 60, and a pushing rake 61 is provided at the output end of the downward cylinder 60, and a pushing finger 62 is provided on the pushing rake 61, and the pushing rake 61 is provided with a second driving mechanism for controlling its horizontal sliding on the beam 2. The second driving mechanism includes a second slide rail 58, and a slider is provided on the second slide rail 58. The downward cylinder 60 is installed on the slider, and a step pulley is provided at both ends of the beam 2 located on the second slide rail 58, and a second driving motor 59 is provided on the step pulley. The slider is driven by the second driving motor 59 to realize the horizontal movement on the second slide rail 58. When the ice cream is transported by the baffle to the front of the material placement table 55, the second driving motor 59 is used to move the pushing rake 61 to the back of the ice cream, and cooperate with the downward cylinder 60 to push the ice cream onto the material placement table 55, waiting to be grabbed by the robotic arm 40;

[0050] Furthermore, the material placing mechanism includes a material placing platform 55, on which guide plates 56 are symmetrically provided. The guide plates 56 are equipped with a gathering cylinder 57. When the ice cream is pushed forward by the pushing rake 61, in order to improve the integrity of the ice cream, the gathering cylinder 57 drives the guide plates 56 to gather the ice cream together, so that the pushing rake 61 can completely move the ice cream into the working range of the sponge suction cup 41.

[0051] Furthermore, in order to improve the applicability of the second conveying unit 4 and to be able to transfer packaging boxes 64 of different widths, an adjustment frame 23 is provided on the first bracket 22, and the second push plate is installed on the adjustment frame 23. The adjustment frame 23 is provided with an adjustment waist hole 24 along the movement direction of the second push plate 25. The adjustment frame 23 is provided with an adjustment bolt through the adjustment waist hole 24. The position of the second push plate 25 can be adjusted forward and backward according to the width of the packaging box 64 by adjusting the waist hole 24 and the adjustment bolt.

[0052] It should be noted that the first driving cylinder 13 , the second driving cylinder 21 , and the third driving cylinder 26 used in the present invention are all rodless cylinders.

[0053] It should be noted that the width of the pushing finger 62 is smaller than the distance between the two baffles. In this way, when pushing the material onto the material placement table 55, the pushing finger 62 is placed between the two baffles to push the ice cream out.

[0054] When in use, the packaging box 64 first arrives at the position of the first push plate 17 from the first conveying unit 3, and then the first push plate 17 pushes the packaging box 64 from the feed port 19 to the second push plate 25, and then the second push plate 25 pushes the packaging box 64 to the position of the third push plate 28, waiting for packaging. During packaging, the opening cylinder 37 is used to drive the lever 38 and the paddle 39 to realize the outward flipping of the folding of the packaging box 64, and then the first drive motor 46 is used to drive the mechanical arm 40 to move to the material placement table 55, and the sponge suction cup 41 is used to adsorb the ice cream and place it in the packaging box 64. When packaging is completed, the third push plate 28 pushes the packaging box 64 out of the discharge port 20 to the conveyor belt 30 of the third conveying unit 5. In this process, the moving path of the packaging box 64 changes from a straight line to a stepped movement, thereby changing the layout of each unit in the frame 1, further reducing the length and volume of the entire cartoning machine, and reducing the floor space in the workshop.

[0055] The above description is only a preferred specific embodiment of the present invention and does not limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
