[0029] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the following will further introduce this solution in detail in combination with specific embodiments.
[0030] Such as Figures 1 to 7As shown in the figure, an embodiment of the present utility model provides an automatic cigarette-taking and weighing device, which includes a base 11, a conveying hopper 51, a cigarette-taking claw 31, a vertical guide rail 21, a horizontal guide rail 41, and a controller. A support frame is arranged on one side of the base 11, and a weighing platform 12 is arranged on the other side of the base 11. A weighing device is arranged on the weighing platform 12. The upper end of the vertical guide rail 21 is vertically connected to the bottom surface of the top plate 13 of the support frame. The cigarette-taking claw 31 is slidably arranged on the vertical guide rail 21, and a first driving mechanism for driving the sliding of the cigarette-taking claw is arranged on the vertical guide rail 21. The horizontal guide rail 41 is arranged at the rear side of the base. The conveying hopper 51 is slidably arranged on the horizontal guide rail 41. A second driving mechanism for driving the sliding of the conveying hopper is arranged on the horizontal guide rail 41. The opening of the conveying hopper 51 faces upward, and a third driving mechanism for controlling the opening and closing of its bottom plate is arranged on the conveying hopper. At least two cigarette-taking grooves 34 for accommodating cigarette sticks are arranged on the cigarette-taking claw 31. The extending direction of the cigarette-taking groove 34 is the same as the extending direction of the cigarette stick. At least two air suction holes 37 are arranged at the bottom of the cigarette-taking groove 34. An air inlet pipe 36 is arranged on the cigarette-taking claw. A communication channel for communicating the air inlet pipe with each air suction hole is arranged inside the cigarette-taking claw. The air inlet pipe 36 is connected to a negative pressure air source through a connecting pipe. A regulating valve is arranged on the connecting pipe. The regulating valve, the first driving mechanism, the second driving mechanism, and the third driving mechanism are respectively electrically connected to the controller.
[0031] When the automatic cigarette-taking and weighing device provided by the embodiment of the present utility model is in use, negative pressure suction air is supplied into the air inlet pipe 36. The negative pressure in the air suction holes 37 can adsorb the cigarette sticks in the cigarette-taking grooves 34 to achieve cigarette stick sampling. Then, the cigarette-taking claw 31 slides to the upper end of the vertical guide rail 21, and the conveying hopper 51 slides to the left end of the horizontal guide rail 41 and is located directly below the cigarette-taking claw. Then, the regulating valve is closed, so that the negative pressure suction air in the air suction holes is lost. At this time, the cigarette sticks in the cigarette-taking grooves will fall into the conveying hopper. Then, the conveying hopper 51 slides to the right end of the horizontal guide rail and is located directly above the weighing device. Then, the bottom plate of the conveying hopper is opened, and the cigarette sticks are dropped onto the weighing device, and the weighing device is used to weigh the cigarette sticks. It can be seen that the present utility model can better achieve automatic cigarette-taking and weighing, thereby effectively reducing the labor intensity of operators. At the same time, since there is no need to pinch the cigarette sticks by hand, the number of scrapped cigarette sticks is effectively reduced.
[0032] Further, the number of the cigarette-taking grooves 34 is five, and three air suction holes 37 are arranged in the extending direction of each of the cigarette-taking grooves 34, so that the cigarette-taking claw can suck five cigarette sticks at a time, improving the cigarette-taking efficiency. It can be understood that the controller can control the on-off and the magnitude of the negative-pressure air suction in each air suction hole 37 by controlling the opening and closing of the regulating valve and the magnitude of the opening angle.
[0033] Preferably, first in-place sensors for detecting whether the cigarette-taking claw or the first slider moves in place are arranged at both the upper and lower ends of the vertical guide rail 21, and second in-place sensors for detecting whether the conveying hopper or the second slider moves in place are arranged at both the left and right ends of the horizontal guide rail 41. Each in-place sensor is electrically connected to the controller, so that the controller can conveniently judge whether the cigarette-taking claw and the conveying hopper move in place, and further facilitate the controller to control the opening and closing timing of the regulating valve and the bottom plate, ensuring the normal operation of the device. Each of the above in-place sensors can be a photoelectric sensor.
[0034] Specifically, a vertical sliding groove and a first slider slidably engaged with the vertical sliding groove are arranged at the rear side of the vertical guide rail 21. The first slider is movably fitted in the vertical sliding groove, and the cigarette-taking claw is arranged on the first slider. The first driving mechanism is used to drive the first slider to move in the vertical sliding groove. To realize the driving of the first slider, the first driving mechanism can include a first driving motor and a first screw rod vertically arranged in the vertical sliding groove. A threaded hole for threadedly engaging with the first screw rod is arranged on the first slider. The output shaft of the first driving motor is coaxially connected with the first screw rod, and the first driving motor is electrically connected to the controller. In this way, the controller can control the forward and reverse rotation and the start and stop of the first driving motor. When in use, only by rotating the first driving motor can the first screw rod be driven to rotate accordingly. By using the threaded engagement between the first screw rod and the first slider, the first slider will be driven to move along the vertical sliding groove, thus realizing the driving of the first slider. Similarly, a horizontal guide groove and a second slider slidably engaged with the horizontal guide rail are arranged at the front side of the horizontal guide rail 41. The second slider is movably fitted in the horizontal guide groove, and the conveying hopper is arranged at the front end of the second slider. The second driving mechanism is used to drive the second slider to move in the horizontal guide groove. The second driving mechanism can have the same structure as the first driving mechanism, that is, it also includes a driving motor and a screw rod, which will not be elaborated here. Preferably, both the vertical sliding groove and the horizontal guide groove 43 are T-shaped grooves, and both the first slider 22 and the second slider have T-shaped sliding parts adapted to the T-shaped grooves, so as to conveniently realize the movable fitting between the two.
[0035] Preferably, a plurality of arc-shaped grooves 52 for accommodating cigarette sticks are uniformly arranged in the extending direction of the bottom plate of the conveying hopper 51, so that each cigarette stick can be better stored in each arc-shaped groove 52.
[0036] Specifically, the bottom surfaces of the left and right ends of the horizontal guide rail 41 are respectively connected to the rear side of the base 11 through two support rods 15, thus conveniently realizing the connection between the horizontal guide rail 41 and the base 11.
[0037] In an embodiment, the cigarette picking claw 31 includes a horizontal plate 32 and an inclined plate 33 connected to the rear side of the horizontal plate. The inclined plate 33 is inclined downward. The horizontal plate 32 and the inclined plate 33 form a V-shaped plate. Each cigarette picking groove 34 is evenly distributed on the inclined plate, and the air inlet pipe 36 is arranged on the horizontal plate. Preferably, weight reduction holes 35 are arranged on both the horizontal plate and the inclined plate, so as to effectively reduce the weight of the cigarette picking claw. Preferably, the horizontal plate 32 is rotatably connected to the first slider on the vertical guide rail through a rotating shaft. A second driving motor electrically connected to the controller is arranged on the first slider. The second driving motor is used to drive the rotating shaft to rotate. By using the controller to control the rotation angle and rotation direction of the second driving motor, the angle between the horizontal plate and the inclined plate and the horizontal plane can be conveniently adjusted, so that the cigarette picking operation of the cigarette picking claw at the cigarette outlet of the cigarette making machine is more convenient and fast. With this solution, when picking up cigarettes, the inclined plate can be at -30° with the horizontal plane to facilitate sucking the cigarette sticks and completing the cigarette stick sampling; when the cigarette picking claw moves to the upper end of the vertical guide rail, the inclined plate can be at 60° with the horizontal plane. When the conveying hopper moves to directly below the cigarette picking claw, the inclined plate is flush with the horizontal plane, and then the regulating valve is closed, so that the cigarette sticks in the cigarette picking grooves fall into the conveying hopper.
[0038] Preferably, the upper end of the vertical guide rail is slightly higher than the horizontal guide rail. In an embodiment where the cigarette picking claw can rotate, the upper end of the vertical guide rail can be flush with the horizontal guide rail.
[0039] Specifically, the third driving mechanism includes a third driving motor electrically connected to the controller. The front side of the bottom plate 53 of the conveying hopper is rotatably connected to the left side plate 54 and the right side plate 55 of the conveying hopper through a rotating shaft respectively. The output shaft of the third driving motor 57 is coaxially connected to the rotating shaft. With this solution, by controlling the rotation direction and rotation angle of the third driving motor through the controller, the opening and closing of the bottom plate can be conveniently realized.
[0040] Preferably, the third driving motor is arranged on the left side plate of the conveying hopper. The rear side of the bottom plate of the conveying hopper is not connected to the rear side plate 56 of the conveying hopper. Driven by the third driving motor, when the rear side of the bottom plate fits with the rear side plate, the bottom plate is closed, and when the rear side of the bottom plate is away from the rear side plate, the bottom plate is opened, so that all the cigarette sticks fall onto the weighing device.
[0041] Furthermore, the top plate 13 of the support frame is a rectangular plate, and the top plate is connected to the base 11 through three connecting rods 14, thus conveniently realizing the connection between the top plate and the base. Specifically, a connecting rod is provided at each of the two corners on the right side of the top plate, a connecting rod is provided at the middle position on the front side of the top plate, and the upper end of the vertical guide rail is connected to the left end of the top plate.
[0042] Specifically, the weighing device is an electronic scale. It can be understood that the sampling frequency and speed of the cigarette can be adjusted according to the number of cigarettes to be weighed.
[0043] The general working process of the present invention is as follows:
[0044] The controller controls the first driving mechanism to drive the cigarette picking claw 31 to move along the vertical guide rail 21 to the lower end of the vertical guide rail, and is located at the cigarette outlet of the cigarette making machine. The controller controls the regulating valve to open, and uses the suction holes 37 to adsorb the cigarette into the cigarette picking groove 34 of the cigarette picking claw, and then moves the cigarette picking claw to the upper end of the vertical guide rail;
[0045] The controller controls the second driving mechanism to drive the conveying hopper 51 to move to the left end of the horizontal guide rail 41 and be located directly below the cigarette picking claw. The controller closes the regulating valve so that the cigarette in the cigarette picking groove falls into the conveying hopper;
[0046] The conveying hopper 51 is moved to the right end of the horizontal guide rail 41 and is located directly above the electronic scale. The controller controls the third driving mechanism to drive the bottom plate to open, so that the cigarette in the conveying hopper falls onto the tray of the electronic scale, and the electronic scale weighs the cigarette.
[0047] The overall structure of the present invention is reasonable, stable in operation, convenient to adjust, and has a high degree of automation; at the same time, it can realize automatic cigarette picking and weighing; and it can pick five cigarettes at a time, improving the cigarette sampling speed compared with the prior art; and it can also reduce the labor intensity, improve the production efficiency, reduce the number of scrapped cigarettes during the cigarette weighing process, and enhance the economic benefits.
[0048] The above is only the preferred embodiment of the present invention. It should be noted that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. Moreover, after reading the content of the present invention, those skilled in the relevant art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
