[0004] With the improvement of production efficiency, automatic case packing machines have been widely used. Case packing fixtures are an important component of automatic case packing machines. In the existing technology, the gripper of the case packing fixture is not only complex in structure, but also corresponds to the bottle mouth of the plastic bottle. The gripper needs to correspond to the product position one by one, which is not compatible with the product. The gripper installation requires a certain amount of space. When changing products, the gripper installation space needs to be re-adjusted. If the spacing is too small, the bottle body will tilt, increasing the difficulty of case packing. In addition, there are high requirements for the neatness of product placement. If a product is placed in the wrong position, the corresponding gripper may not be able to grab the product, or even affect the grasping of surrounding grippers, reducing efficiency.

[0007] The translation distance of the splint driving mechanism is adjustable. The splint driving mechanism has at least a first translation distance and a second translation distance. The first translation distance is greater than the second translation distance. The first translation distance is the translation distance of the splint clamping the plastic bottle product, and the second translation distance is the translation distance of the splint in the packaging box.

[0008] Preferably, the number of the splints is 3 or 4. When there are 3 splints, one of the splints is a right-angled folded splint.

DETAILED DESCRIPTION

[0021] Figures 1-3 This is the best embodiment of the present invention, Figures 1-3 The utility model is further described.

[0022] Example 1:

[0023] Reference Figures 1-3 The packing fixture includes a splint, a splint driving mechanism, a pressure plate 11 and a pressure plate driving mechanism. The splint driving mechanism drives multiple splints to move horizontally to enclose a quadrilateral clamping space. The pressure plate 11 is arranged in the clamping space, and the pressure plate driving mechanism drives the pressure plate 11 to rise and fall; the translation distance of the splint driving mechanism is adjustable, and the splint driving mechanism has at least a first translation distance and a second translation distance. The first translation distance is greater than the second translation distance, wherein the first translation distance is the translation distance of the splint clamping the plastic bottle product, and the second translation distance is the translation distance of the splint in the packaging box.

[0024] In this embodiment, there is a right-angled folded fixed splint 3 and two sliding splints, and the sliding splints are respectively a long-side movable splint 4 and a short-side movable splint 5, which are arranged on the opposite side of the right-angled folded fixed splint 3, forming a rectangle with the right-angled folded fixed splint 3, and the splint driving mechanism is also provided with two groups. The splint driving mechanism in this embodiment is a two-stroke cylinder, which connects the splint and drives the splint to move along the guide rail 6.

[0025] The double-stroke cylinder includes a cylinder body 20 and a push rod 18. The first charging and discharging port 15, the second charging and discharging port 16 and the third charging and discharging port 17 are arranged on one side of the cylinder body 20 and connected to the air cavity 19 inside the cylinder body 20. The cylinder stroke is controlled by the opening and closing of these three charging and discharging ports, driving the push rod 18 to drive the movable splint.

[0026] An automatic cartoning machine using a cartoning fixture includes a fixed flange 1, a connecting plate 2 and a transport device. The fixed flange 1 is connected to the transport device. The connecting plate 2 is arranged on the lower side of the fixed flange 1. The clamping plate driving device is arranged on the lower side of the connecting plate 2 and drives the sliding clamping plate. The fixed clamping plate 3 is fixed on the lower side of the connecting plate 2. The pressing plate driving mechanism is arranged on the lower side of the connecting plate 2 and the bottom end is connected to the pressing plate 11.

[0027] The fixed splint 3 is fixed to the lower side of the connecting plate 2 by bolts, and the long side movable splint 4 and the short side movable splint 5 are slidably connected to the lower side of the connecting plate 2 through two sets of guide rails 6. Two sets of sliders are provided on the upper side of the long side movable splint 4, and a set of sliders are provided on the short side movable splint 5, and the sliders are set in the guide rails 6.

[0028] The long side cylinder 7, short side cylinder 8 and bottle pressing cylinder 9 are all directly fixed to the bottom of the connecting plate 2. The guide rod of the long side cylinder 7 is fixedly connected to the long side movable splint 4 through the long side cylinder connecting plate 10. The guide rod of the short side cylinder 8 is fixedly connected to the short side movable splint 5. The guide rod of the compression cylinder 9 is fixedly connected to the pressing plate 11. The long side cylinder 7 and the short side cylinder 8 respectively drive the long side movable splint 4 and the short side movable splint 5 to move horizontally along the guide rail 6, and the compression cylinder 9 drives the pressing plate 11 to rise and fall.

[0029] The pressure plate 11 is rectangular in shape. When the packing fixture clamps the plastic product and puts it into the packaging box, the movable splint is loosened a short distance. At this time, the compression cylinder 9 drives the pressure plate 11 to descend, supporting the plastic product and making the splint better detach from the packaging box. Therefore, the size of the pressure plate 11 is smaller than the size of the space formed by the maximum translation distance of the splint in the packaging box.

[0030] The long side cylinder connecting plate 10 is provided with a vertical first connecting plate 12, a third connecting plate 14 and a horizontal second connecting plate 13. The third connecting plate 14 is arranged on the side of the first connecting plate 12 close to the long side cylinder 7. The first connecting plate 12 is connected to the guide rod of the long side cylinder 7, and the third connecting plate 14 is connected to the long plate movable splint 4. A through groove is provided on the long plate movable splint 4, so that the guide rod of the long side cylinder 7 passes through the barrel groove and is connected to the first connecting plate 12. The second connecting plate 13 connects the first connecting plate 12 and the third connecting plate 14 to form a whole.

[0031] The long side cylinder 7 is installed along the short side of the connecting plate 2. The short side distance is shorter, and the long side cylinder 7 is longer than the installation distance. The guide rod end of the long side cylinder 7 extends out of the edge of the connecting plate 2. Therefore, a long side cylinder connecting plate 10 is set, and the third connecting plate 14 is set on the side of the first connecting plate 12 close to the long side cylinder 7, and is retracted inward for a distance to connect to the long side movable splint 4. Not only is the overall appearance beautiful, but the translation distance of the guide rod is also shortened.

[0032] In this embodiment, the transport device is a manipulator connected to fixed flange 1, which drives a packing fixture mounted on connecting plate 2 to pick up plastic products. Multiple packing fixtures can be arranged side by side on connecting plate 2 to pick up multiple boxes of plastic bottle products at once. In this embodiment, two sets of packing fixtures are arranged side by side on connecting plate 2, allowing two boxes of plastic products to be picked up at a time, improving packing efficiency.

[0033] Working process:

[0034] Plastic bottles are neatly arranged on the bottle collection platform according to the actual required number of boxes and arrangement. The robot drives the connecting plate 2 and the packing fixture to move above the plastic bottles. Then, the long-side cylinder 7 and the short-side cylinder 8 push out the guide rods, respectively driving the long-side movable clamp 4 and the short-side movable clamp 5 to move outward along the guide rail 6 to the maximum translation distance of the first translation distance. The packing fixture then moves down, and the quadrilateral space formed by the fixed clamp 3, the long-side clamp 4, and the short-side clamp 5 completely surrounds the plastic bottles. The long-side cylinder 7 and the short-side cylinder 8 guide rods retract, respectively driving the long-side clamp 4 and the short-side clamp 5 to retract inward to the minimum translation distance of the first translation distance, thus clamping the plastic bottles.

[0035] The manipulator drives the packing fixture and the product to the inside of the packaging box. The long-side cylinder 7 and the short-side cylinder 8 extend a certain distance to the outward guide rod, which is the maximum translation distance of the second translation distance. At this time, the plastic bottle product is in a relaxed state. Then the packing fixture moves up, and at the same time, the guide rod of the bottle pressing cylinder 9 extends, driving the pressure plate 11 to descend, supporting the plastic bottle product until the packing fixture completely exits the packaging box, so that the plastic bottle product is put into the packaging box, and then the manipulator drives the packing fixture to repeat the above process.

[0036] Example 2:

[0037] The difference between this embodiment and the first embodiment is that: there are three splints, all of which are sliding splints, of which the third sliding splint is a right-angled folded splint, and there are three groups of splint driving mechanisms, which respectively drive the three sliding splints to translate.

[0038] Example 3:

[0039] The difference between this embodiment and the first embodiment is that there are four splints, two of which are fixed splints 3 and the other two are sliding splints. The fixed splints 3 and the sliding splints are arranged opposite to each other to form a rectangle.

[0040] Example 4:

[0041] The difference between this embodiment and the first embodiment is that the clamping plate driving mechanism is two single-stroke cylinders connected in series, and the push rod is connected to the movable clamping plate, so that the translation distance of the movable clamping plate can be adjusted.

[0042] Embodiment 5:

[0043] The difference between this embodiment and the first embodiment is that the clamping plate driving mechanism is an electric cylinder, the lead screw is connected to the movable clamping plate, and the servo motor drives the lead screw to make the translation distance of the movable clamping plate adjustable.

[0044] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
