[0023] The specific implementation manner of the present application is described below with reference to the accompanying drawings.

[0024] In the present application, the terms "transverse" or "lateral" refer to a generally horizontal direction, "vertical" or "up and down" refer to a direction generally perpendicular to the horizontal plane, "front" refers to a direction consistent with the conveying direction of the packaging barrel, "rear" refers to a direction opposite to the conveying direction of the packaging barrel, and "lateral" or "lateral" refers to the lateral direction relative to the front-to-back direction, generally perpendicular to the front-to-back direction or forming other angles.

[0025] Reference Figure 1 A barrel taking mechanism 100 is used to move a packaging barrel 10 from a barrel taking position (such as Figure 1 The packaging barrel 10 is moved from the position where the packaging barrel 10 is located to the position to be loaded (not shown in the figure), and during the movement, the packaging barrel 10 is moved from the position where the packaging barrel 10 is located to the position to be loaded (not shown in the figure). Figure 1 The horizontal orientation shown is flipped to an open-up orientation.

[0026] To this end, the barrel taking mechanism 100 includes a swing arm assembly 200 , an arm assembly 300 and a guide plate 400 .

[0027] exist Figure 1 In the illustrated embodiment, the swing rod assembly 200 includes two swing rods 210 disposed opposite to each other. Each swing rod 210 has a pivot 212 and a first swing arm 214 and a second swing arm 216 that rotate around the pivot 212. The first swing arm 214 and the second swing arm 216 form a fixed angle. This angle can be set to different values ​​according to different application environments. Figure 1-2 The two oppositely arranged swing rods can ensure the stable movement and rotation of the swing rod assembly. Therefore, although Figure 1 The embodiment in the embodiment is provided with two swing rods, but those skilled in the art will appreciate that in some application environments, only one swing rod may be provided.

[0028] A rotating shaft 220 is provided between the pivots 212 of the two swing arms, and a driving rod 230 is connected thereto. One end of the driving rod 230 is sleeved on the rotating shaft 220 and can rotate around the rotating shaft 220. The other end of the driving rod 230 can be connected to a movable component 20 of a driving mechanism, such as a piston of an air cylinder or a hydraulic cylinder, or a worm of a worm gear mechanism.

[0029] A support arm crossbeam 240 is also fixedly connected between the two swing rods 210 for fixing the support arm assembly 300 .

[0030] The swing arm assembly 200 further includes a first roller 250 and a second roller 260 to facilitate the movement of the swing arm assembly. The first roller 250 is disposed on the first swing arm 214, preferably at the free end of the first swing arm 214. The second roller 260 is disposed on the pivot 212 and rotates coaxially with the pivot 212. In one example, the first swing arm 214 has a horizontally extending portion, so that the force pushing the first roller 250 is consistent with the moving direction of the first roller 250.

[0031] In order to ensure that the first roller 250 and the second roller 260 can move in the desired track, guide plates 400 are respectively provided on both sides of the swing arm assembly 200. Figure 4 The guide plate 400 is provided with a guide groove for guiding the movement of the first and second rollers. Figure 3As shown, the first roller 250 is configured to move along the first guide slot 410, and the second roller 260 is configured to move along the second guide slot 420. A curved portion 412 is formed at the end of the first guide slot 410 to guide the moving direction of the first roller 250 to deflect by 90 degrees, so that the first swing arm 214 rotates 90 degrees about the pivot 212, that is, rotates 90 degrees with the pivot as the rotation axis, so that the swing arm assembly as a whole rotates 90 degrees about the pivot.

[0032] In the present embodiment, the angle between the first swing arm 214 and the second swing arm 216 is an obtuse angle, so when the swing arm assembly is in the barrel taking position and the second swing arm 216 needs to be kept vertical, the first swing arm 214 forms an angle with the horizontal direction, so that the first roller 250 and the second roller 260 have a height difference in the vertical direction. Therefore, the guide plate 400 is provided with two guide grooves. However, in other embodiments of the utility model, for example, when the angle between the first swing arm and the second swing arm is 90 degrees, in the barrel taking position, the first swing arm is substantially consistent with the horizontal direction, so the guide plate can be provided with only one guide groove. Similarly, the end of the guide groove is provided with a curved portion to guide the first swing arm to rotate 90 degrees about the pivot. In other embodiments, the moving direction of the second roller can also be deflected by 90 degrees.

[0033] In this embodiment, refer to Figure 1 The arm assembly 300 includes a suction cup support rod 310 and a suction cup mechanism 320. The lower end of the suction cup support rod 310 is fixed to the arm cross beam 420. The dishwashing mechanism 320 is fixed to the upper end of the suction cup support rod 310. The suction cup mechanism 320 can be a vacuum suction cup mechanism, which has a vacuum generator 322 and a suction cup (not shown in the figure). The suction cup support rod 310 is consistent with the orientation of the second swing arm 216 to ensure that the swing arm assembly 200 and the arm assembly 300 have the same rotation angle.

[0034] When the mechanism is running, it is necessary to take the barrel position (such as Figure 1 The packaging barrel 10 is moved to the position to be loaded (not shown in the figure, referred to as the "first station") and the position to be loaded (not shown in the figure, referred to as the "second station") and the packaging barrel 10 is turned over 90 degrees. Figure 1In the first station, the packaging barrel 10 is horizontally placed at the end of the conveyor belt 30 and is lifted and positioned by the positioning mechanism. The opening of the suction cup (not shown in the figure) is directly opposite to the bottom center of the packaging barrel 10, and the suction cup support rod 310 and the second swing arm 216 are in a substantially vertical position. When the suction cup contacts and presses on the bottom of the packaging barrel, for example, under the action of the backward thrust from the driving mechanism, the cavity between the suction cup and the bottom of the packaging barrel 10 forms a vacuum under the action of the vacuum generator 322, so that the suction cup captures the packaging barrel. Afterwards, the driving mechanism applies a pulling force forward, and pulls the swing arm assembly 200 to move forward by driving the pull rod 230. At this time, the packaging barrel 10 maintains a horizontal position and moves forward accordingly. When the first roller 250 reaches the end of the first guide groove 410, it is affected by the inner wall of the guide groove 410, and the movement direction of the first roller 250 changes and continues to move along the curved portion 412. At this time, the first swing arm 214 rotates relatively around the pivot 212. Then, the second swing arm 216 rotates at the same time under the action of the lever, driving the arm assembly 300 to rotate 90 degrees, thereby turning the packaging barrel 10 from the horizontal position to a vertical position with the barrel bottom facing downward and the barrel mouth facing upward. After that, the vacuum generator 322 eliminates the vacuum degree and places the packaging barrel 10 on the workbench at the pre-loading position.

[0035] In the above description, the details of the technical solution of the present invention are explained. However, those skilled in the art can understand that the present invention is not limited to the specific details listed in the above embodiments, but can be changed within the scope defined by the claims.
