Description

Technical Field

[0001] This utility model relates to the field of tobacco logistics packaging, and in particular to a telescopic robotic arm for turnover boxes. Background Technology

[0002] Processed boxed tobacco usually needs to be wrapped or bagged into cartons of cigarettes. Then the cartons of cigarettes are sorted and packaged, and then transported to various marketing outlets for sale. Flexible turnover boxes, or turnover boxes for short, are an important tool in the packaging of cartons of cigarettes.

[0003] In existing technology, during the replenishment of turnover boxes, the sorted turnover boxes are manually placed onto the conveyor. Since tobacco packaging equipment requires a large number of turnover boxes every day, manual stacking and placement require two people, which is not only time-consuming and labor-intensive, but also prone to causing equipment malfunction alarms due to uneven stacking. Therefore, most of the time, robotic arms are used to handle and stack the turnover boxes. However, when a robotic arm holds several turnover boxes at a time, some turnover boxes may slip during the transfer, affecting work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a telescopic manipulator for turnover boxes in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A telescopic manipulator for turnover boxes includes a conveyor, a trolley placed on one side of the conveyor, a transfer mechanism above the conveyor and trolley, and a clamping assembly below the transfer mechanism.

Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5 As shown, a telescopic manipulator for turnover boxes includes a conveyor 101, a trolley 102 placed on one side of the conveyor 101, and turnover boxes that need to be transferred to the conveyor 101 placed on the trolley 102.

[0026] A transfer mechanism is provided above the conveyor 101 and the trolley 102. The transfer mechanism includes a first mounting frame 201 and a second mounting frame 202 placed on the ground on both sides of the conveyor 101. The first mounting frame 201 and the second mounting frame 202 are U-shaped with their openings facing downwards. Anti-slip pads are placed at the bottom of the first mounting frame 201 and the second mounting frame 202. There is a gap between the first mounting frame 201 and the second mounting frame 202 and the side wall of the conveyor 101. A slide rail 203 is fixedly connected between the first mounting frame 201 and the second mounting frame 202. A slider 204 is slidably connected on the slide rail 203. An electric push rod 205 is fixedly connected to the bottom of the slider 204. A mounting plate 206 is fixedly connected to the bottom of the electric push rod 205.

[0027] The slider 204 is driven by a transmission assembly, which includes a friction wheel rotatably connected to the slider 204. The friction wheel is driven to rotate by a rotary motor. A friction belt is fixedly connected between the first mounting bracket 201 and the second mounting bracket 202. While the friction wheel rotates along the friction wheel, it drives the slider 204 to move along the slide rail 203.

[0028] The trolley 102 is located between the second mounting frames 202. A protective baffle 6 is fixedly connected between the second mounting frames 202 and the conveyor 101. The protective baffle 6 is located in front of and behind the trolley 102. The protective baffle 6 isolates the transfer area to prevent turnover boxes from falling and injuring workers during the transfer process.

[0029] A clamping assembly is provided below the transfer mechanism. The clamping assembly includes two clamping plates 303 arranged symmetrically front to back. The clamping plates 303 have an installation cavity inside. The clamping assembly also includes a vertical plate 301 fixedly connected to the top of the mounting plate 206. A hydraulic cylinder 302 is fixedly connected to the vertical plate 301. The movable end of the hydraulic cylinder 302 is fixedly connected to the clamping plate 303. Several protrusions are fixedly connected to the side of the two clamping plates 303 that are close to each other. The protrusions increase the friction of the clamping plates 303 and improve the stability of the clamping plates 303 when clamping the turnover box.

[0030] An auxiliary support mechanism is provided inside the clamping plate 303. The auxiliary support mechanism includes two rotating shafts 401. The rotating shafts 401 are rotatably connected in the mounting cavity. The bottom end of the rotating shaft 401 extends out of the clamping plate 303 and is fixedly connected to a support rod 402. The upper surface of the support rod 402 is at the same level as the lower surface of the clamping plate 303.

[0031] The auxiliary support mechanism also includes a power assembly, which drives two rotating shafts 401 to rotate in opposite directions. The power assembly includes a stepper motor 501 fixedly connected to the top of the clamping plate 303. The output end of the stepper motor 501 is connected to one of the rotating shafts 401 through a coupling. A drive shaft 502 is rotatably connected inside the mounting cavity. Gears 503 are fixedly connected to both the drive shaft 502 and one of the rotating shafts 401. The two gears 503 mesh with each other. A belt 504 is connected between the drive shaft 502 and the other rotating shaft 401 through a pulley. Both the gears 503 and the belt 504 are located inside the mounting cavity.

[0032] Working principle: In use, push the trolley 102 carrying the required turnover box into the area between the two protective baffles 6. The slider 204 moves the clamping plate 303 above the trolley 102. The electric push rod 205 lowers the clamping plate 303 to the front and rear sides of the turnover box. The hydraulic cylinder 302 moves the clamping plate 303 closer together to clamp the turnover box. The electric push rod 205 raises the clamping plate 303 to a suitable height. After the clamping plate 303 clamps the turnover box, the stepper motor 501 is started. The stepper motor 501 drives one of the rotating shafts 401 to rotate. The rotating shaft 401 drives the transmission shaft 502 to rotate through the meshing of two gears 503. The transmission shaft 502 drives the other shaft 502 through the transmission between the pulley and belt 504. The rotating shaft 401 rotates in the opposite direction, rotating the support rod 402 to the bottom of the turnover box to support it, improve the stability of the turnover box during movement, and prevent the turnover box from slipping. Then, the slider 204 moves the turnover box to the top of the conveyor 101. Then, the electric push rod 205 is controlled to drive the clamping plate 303 to move the turnover box downward. When the distance between the turnover box held by the clamping plate 303 and the conveyor 101 or the already stacked turnover boxes reaches the set value, the stepper motor 501 reverses, rotating the support rod 402 to the bottom of the clamping plate 303. Then, the turnover box is placed on the conveyor 101 or the already stacked turnover boxes. The hydraulic cylinder 302 is controlled to release the turnover box from the clamping plate 303, realizing stacking. This avoids multiple people stacking and placing the turnover box, improving work efficiency.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
