Description

Technical Field

[0001] The invention relates to the technical field of tobacco machinery, and in particular to a turning device. Background Art

[0002] like Figure 1 As shown in the figure, the size of the cigarette pack is 94.5mm×70mm×16mm, and the width dimension is larger than that of the conventional cigarette pack. Figure 2 The following is a schematic diagram of a 25-square pack box, the size of which is 350mm×94.5mm×32mm. If the above cigarette packs are still Figure 2 The conventional 25-pack packing method shown in the figure will increase the length of the packing and increase the loss of raw and auxiliary materials such as the packing paper and the transparent paper outside the packing. Therefore, it is necessary to adopt another packing method, that is, a packing method of 10 packs arranged vertically side by side, such as Figure 3 The figure shows a schematic diagram of a vertical ten-pack carton packaging, with a specification size of 160mm×94.5mm×70mm. The vertical ten-pack carton packaging method reduces the use of raw and auxiliary materials, and the appearance is more refined.

The output end of the connecting rod mechanism 23 is connected to the lifting member 21, so that the lifting member 21 can reciprocate in the vertical direction. Through the above transmission mechanism, the output shaft 12 transmits power to the first cam mechanism 22, and then to the connecting rod mechanism 23, and the power is transmitted to the lifting member 21 through the connecting rod mechanism 23, thereby realizing the reciprocating movement of the lifting member 21 in a preset direction, i.e., a vertical direction, and a preset speed.

In this embodiment, the push rod 222 swings up and down. The push rod 222 drives the first connecting rod 231 to drive the second connecting rod 232 to move vertically along the first guide member 233, thereby realizing the vertical movement of the lifting member 21 on the second connecting rod 232. Therefore, the rotation of the first cam 221 ultimately realizes the up and down reciprocating motion of the lifting member 21.

[0047] The lifting member 21 is a lifting plate, which is bolted to the second connecting rod 232. Optionally, the first guide member 233 is a flange member with a sliding hole, the flange member is fixed to the frame 7, and the second connecting rod 232 is slidably connected to the sliding hole of the flange member.

The input end of the first belt transmission mechanism 32 is connected to the output shaft 12, and the output end is connected to the input end of the second cam mechanism 33. The output end of the second cam mechanism 33 is connected to the swing member 31, so that the swing member 31 can reciprocate along the horizontal first direction. Through the above transmission mechanism, the output shaft 12 transmits power to the first belt transmission mechanism 32, and then to the second cam mechanism 33, so that the swing member 31 swings at a preset speed.

[0050] Optionally, the second guide member 333 includes a guide rail 3332 and a slider 3331 slidably connected to the guide rail 3332, the guide rail 3332 extends along a first horizontal direction and is fixed to the frame 7, the slider 3331 is connected to the end of the swing rod 332, the slider 3331 is connected to a transfer rod 35, the transfer rod 35 extends along the first horizontal direction, the transfer rod 35 is connected to an extension rod 36, the extension rod 36 extends in a vertical direction, and the swing member 31 is connected to the end of the extension rod 36. The specific lengths of the extension rod 36 and the transfer rod 35 are set according to actual needs to ensure that the swing member 31 is located at a preset position and prevent the swing mechanism 3 from interfering with other structures.

[0051] like Figure 7 As shown, the flipping mechanism 4 includes a first gear mechanism 42, a second gear mechanism 43, a Maltese wheel 44 and a thumbwheel 45 cooperating with the Maltese wheel 44. The input end of the first gear mechanism 42 is connected to the output shaft 12, and the output end is connected to the thumbwheel 45. The Maltese wheel 44 is connected to the input end of the second gear mechanism 43. The output end of the second gear mechanism 43 is connected to the flipping member 41. One of the first gear mechanism 42 and the second gear mechanism 43 is a helical cylindrical gear mechanism, and the other is a spur cylindrical gear transmission, so that the output shaft 12 extends along the first horizontal direction, and the rotation center line of the flipping member 41 is parallel to the second horizontal direction.

[0052] In this embodiment, the flip mechanism 4 further includes a third gear mechanism 410 to further achieve speed reduction. The first gear mechanism 42, the second gear mechanism 43 and the third gear mechanism 410 all include a driving gear and a driven gear, and the third gear mechanism 410 and the second gear mechanism 43 also include an intermediate gear, and the driving gear and the driven gear are meshed through the intermediate gear. The first gear mechanism 42 is a helical cylindrical gear mechanism, and its driving gear and the driven gear are meshed and connected.

[0053] The driving gear of the third gear mechanism 410 is connected to the output shaft 12, the driven gear and the driving gear of the first gear mechanism 42 are connected to the same rotating shaft, the driven gear and the thumbwheel 45 of the first gear mechanism 42 are simultaneously connected to the first rotating shaft 48, the Maltese wheel 44 and the driving gear of the second gear mechanism 43 are connected to the same rotating shaft, and the driven gear and the flip member 41 of the second gear mechanism 43 are both connected to the third rotating shaft 420. The output shaft 12 transmits power to the third gear mechanism 410, the first gear mechanism 42, the combined mechanism of the Maltese wheel 44 and the thumbwheel 45, the second gear mechanism 43 and the flip member 41 in sequence. Through the cooperation of the Maltese wheel 44 and the thumbwheel 45, the intermittent motion of the second gear mechanism 43, the third rotating shaft 420 and the flip member 41 is realized to cooperate with the lifting member 21 and the swing member 31.

[0054] The flip mechanism 4 also includes a hand wheel 46 and a second belt transmission mechanism 47. The second belt transmission mechanism 47 includes a driving pulley, a driven pulley, and a belt wound around the driving pulley and the driven pulley. The input end of the second belt transmission mechanism 47, i.e., the driving pulley, is directly connected to the hand wheel 46 or connected to the hand wheel 46 through a rotating shaft, and the output end, i.e., the driven pulley, is connected to the first rotating shaft 48, i.e., the driven pulley, the dial wheel 45, and the driven gear of the first gear mechanism 42 are all connected to the first rotating shaft 48. When the driving member 11 of the driving mechanism 1 stops running, the hand wheel 46 is dialed to transmit power to the flip member 41 through the second belt transmission mechanism 47, so that the phase of the Maltese wheel 44 can be adjusted during the debugging process of the flip device.

[0055] The flip mechanism 4 also includes a negative pressure member 49. The flip member 41 is provided with an adsorption hole, which faces the cigarette pack 100. The negative pressure member 49 is connected to the flip member 41, so that the flip member 41 vacuum adsorbs the cigarette pack 100. Exemplarily, optionally, the flip member 41 includes an intermediate connection part and four flaps, and the four flaps are cross-connected around the intermediate connection part. The intermediate connection part is connected to the third rotating shaft 420. The third rotating shaft 420 rotates to realize that different flaps are used to flip the cigarette pack 100. The negative pressure member 49 includes a negative pressure tube and a control disk 430. There is negative pressure in the negative pressure tube, which is connected to the flip member 41 through the control disk 430 to prevent the cigarette pack 100 from being separated during the rotation process. It should be noted that the function of the control disk 430 is to control the phase of the negative pressure flowing to the flip member 41: in the process of the cigarette pack 100 changing from a horizontal pack to a vertical pack state, there is always negative pressure in the flip member 41, which has an adsorption effect on the cigarette pack 100, preventing the cigarette pack 100 and the flip member 41 from separating, and ensuring the reliability of the flip; when the cigarette pack 100 is in the vertical pack state, the control disk 430 blocks the negative pressure from passing to the flip member 41, so that the cigarette pack 100 and the flip member 41 separate, and prevent the cigarette pack 100 from continuing to rotate with the flip member 41. The specific structure of the control disk 430 refers to the prior art and will not be repeated here. In other embodiments, the negative pressure member 49 may include a vacuum pump and a conduit, the conduit connecting the vacuum pump and the flip member 41, and the switching of the vacuum and non-vacuum states of the flip member 41 is realized by controlling the vacuum pump to be turned on and off.

[0056] like Figure 8 As shown, the flipping device also includes a monitoring system, and the driving mechanism 1 and the safety mechanism 5 are both connected to the monitoring system in communication; when the lifting member 21 lifts the cigarette package 100 and causes the cigarette package 100 to deviate to the first preset position, the safety mechanism 5 is triggered, and the safety mechanism 5 feeds back a signal to the monitoring system. By setting the safety mechanism 5, when the safety mechanism 5 is triggered during the lifting process of the cigarette package 100, the position of the surface cigarette package 100 deviates, and the safety mechanism 5 sends a signal to the monitoring system, and the monitoring system controls the driving mechanism 1 to stop, thereby preventing the damage of the flipping device parts caused by the package blocking phenomenon, thereby improving safety and reliability.

[0057] The safety mechanism 5 includes a carrier 54, a detector 51, two tension springs 52 and two baffles 53. The detectors 51 are all connected to the monitoring system in communication. One end of the two baffles 53 is rotatably connected to the carrier 54, and the other end is correspondingly connected to the carrier 54 through two tension springs 52. For example, the carrier 54 is provided with an avoidance hole 541, and the two baffles 53 are both arranged at the avoidance hole 541. When the lifting member 21 lifts the cigarette package 100 through the avoidance hole 541 to the first preset position, the cigarette package 100 can touch the baffle 53 when it deviates. The detector 51 detects the touched baffle 53 and feeds back the signal to the monitoring system. When the cigarette package 100 touches any baffle 53 during the lifting process, it is triggered. The area surrounded by the baffle 53 is the first preset position, that is, the position of the cigarette package 100 is limited by the baffle 53. The detector 51 is a distance detection sensor. The rotation center lines of the two baffles 53 are parallel to each other and can rotate toward each other or away from each other. When the baffles 53 rotate, the time interval between the two changes, and the detector 51 can detect the bag blocking, preventing the turning device from being forced to run and causing mechanical damage to the transmission parts. By setting the tension spring 52, when the cigarette pack 100 is removed, the tension spring 52 can drive the baffle 53 to automatically reset.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
