Description

Technical Field

[0001] The present invention relates to the technical field of tobacco machinery, 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 packaging method will increase the length of the box and increase the loss of raw and auxiliary materials such as the box paper and the transparent paper outside the box.

[0042] by Figure 1 and Figure 3 The cigarette pack 100 shown is used as an example to illustrate the working process of the flipping device. Figure 4-Figure 8 As shown, this embodiment provides a flipping device, including a frame 7, on which is provided a driving mechanism 1, a lifting mechanism 2, a swinging mechanism 3, and a flipping mechanism 4. The driving mechanism 1 includes a driving member 11 and an output shaft 12 connected to the output end of the driving member 11. The lifting mechanism 2 includes a lifting member 21 connected to the output shaft 12, and the lifting member 21 is capable of vertically lifting a cigarette pack 100 in a horizontally packaged state to a first preset position. The swinging mechanism 3 includes a swinging member 31 connected to the output shaft 12, and the swinging member 31 is capable of pushing a cigarette pack 100 in a horizontally packaged state in the first preset position along a first horizontal direction to a second preset position. The flipping mechanism 4 includes a flipping member 41 connected to the output shaft 12, and the flipping member 41 is capable of rotating a cigarette pack 100 in a horizontally packaged state in the second preset position about a centerline parallel to a second horizontal direction to a vertically packaged state, where the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0043] The driving member 11 drives the output shaft 12 to rotate, and transmits power to the lifting member 21, the swinging member 31 and the flipping member 41 respectively through the output shaft 12, so that the lifting member 21 lifts the cigarette package 100 in the horizontal package state to the required height and the first preset position, and then the swinging member 31 pushes the cigarette package 100 in the horizontal package state from the first preset position to the second preset position along the first horizontal direction to dock with the flipping member 41, and finally the flipping member 41 rotates around the center line parallel to the second horizontal direction to realize the rotation of the cigarette package 100 from the horizontal package state to the vertical package state, that is, Figure 1 The cigarette pack is turned to Figure 3 The cigarette pack state shown in FIG. 1 can thus be packaged in vertical multi-pack boxes, such as Figure 3 By providing only one driving mechanism 1, the coordinated movement of the lifting member 21, the swing member 31 and the turning member 41 is achieved, thus simplifying the structure and reducing the cost.

[0044] like Figure 5 As shown, in the drive mechanism 1, the driving element 11 can be a motor such as a servo motor or a stepper motor. The drive mechanism 1 also includes a third belt transmission mechanism 13, which includes a driving pulley, a driven pulley, and a transmission belt. The transmission belt is wound around the driving pulley and the driven pulley. When the motor is connected to the driving pulley, the output shaft 12 is connected to the driven pulley. When the motor is started, the output shaft 12 is driven to rotate via the third belt transmission mechanism 13.

[0045] like Figure 5 As shown, the lifting mechanism 2 includes a first cam mechanism 22 and a connecting rod mechanism 23. The input end of the first cam mechanism 22 is connected to the output shaft 12, and the output end is connected to the input end of the connecting rod mechanism 23. The output end of the connecting rod mechanism 23 is connected to the lifting member 21, enabling the lifting member 21 to reciprocate in the vertical direction. Through the above-mentioned transmission mechanism, the output shaft 12 transmits power to the first cam mechanism 22, and then to the connecting rod mechanism 23. The power is then transmitted to the lifting member 21 through the connecting rod mechanism 23, thereby achieving reciprocating movement of the lifting member 21 in a predetermined direction, namely the vertical direction, and at a predetermined speed.

[0046] In this embodiment, the first cam mechanism 22 includes a first cam 221 and a push rod 222. The output shaft 12 is provided through the first cam 221. The first cam 221 is a flat cam or a disc cam. One end of the push rod 222 is rotatably connected to the non-wheel center area of ​​the first cam 221. The middle portion of the push rod 222 is vertically connected to a rotating portion 2221. The rotating portion 2221 is rotatably connected to the frame 7. Exemplarily, the rotating portion 2221 is a rotating shaft, which is rotatably connected to the mounting seat 71 on the frame 7. The connecting rod mechanism 23 includes a first connecting rod 231, a second connecting rod 232, and a first guide member 233. The first connecting rod 231 is rotatably connected to the other end of the push rod 222. The first connecting rod 231 and the second connecting rod 232 are hinged. The first guide member 233 is used to guide the second connecting rod 232 in the vertical direction. The lifting member 21 is connected to the second connecting rod 232. The output shaft 12 drives the first cam 221 to rotate, causing the push rod 222 to swing about the rotating portion 2221. The end of the push rod 222 connected to the first cam 221 rotates with the first cam 221, and the end of the push rod 222 connected to the first connecting rod 231 swings back and forth. In this embodiment, the push rod 222 swings up and down. The push rod 222 drives the first connecting rod 231 to move the second connecting rod 232 vertically along the first guide member 233, thereby achieving vertical movement of the lifting member 21 on the second connecting rod 232. Therefore, the rotation of the first cam 221 ultimately achieves the up and down reciprocating motion of the lifting member 21.

[0047] The lifting member 21 is a lifting plate, which is fixed to the second connecting rod 232 with bolts. 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.

[0048] like Figure 6 As shown, the swing mechanism 3 includes a first belt transmission mechanism 32 and a second cam mechanism 33. 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, enabling the swing member 31 to reciprocate along a first horizontal direction. Through this transmission mechanism, the output shaft 12 transmits power to the first belt transmission mechanism 32, and then to the second cam mechanism 33, thereby achieving the swing member 31 swinging at a preset speed.

[0049] In this embodiment, the second cam mechanism 33 includes a second cam 331, a rocker arm 332, and a second guide member 333. The output end of the first belt transmission mechanism 32 is connected to the second cam 331, the rocker arm 332 and the outer periphery of the second cam 331 abut against each other, the second guide member 333 is used to guide the rocker arm 332 in a first horizontal direction, so that the rocker arm 332 moves in the first horizontal direction, and the swinging member 31 is connected to the rocker arm 332. Specifically, the second cam 331 is a cylindrical cam. The driving pulley of the first belt transmission mechanism 32 is connected to the output shaft 12, the driven pulley is connected to the second rotating shaft 34, the second rotating shaft 34 is connected to the second cam 331, and the rocker arm 332 is slidably connected to the frame 7. The outer periphery of the second cam 331 drives the rocker arm 332 to reciprocate along the second guide member 333 in the first horizontal direction. The rocker arm 332 is connected to the swinging member 31, thereby driving the swinging member 31 to reciprocate.

[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 in 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 in the first horizontal direction. The transfer rod 35 is connected to an extension rod 36. The extension rod 36 extends in a vertical direction. 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 in 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. Of the first gear mechanism 42 and the second gear mechanism 43, one is a helical cylindrical gear mechanism and the other is a spur cylindrical gear transmission, so that the output shaft 12 extends along the horizontal first direction and the rotation center line of the flipping member 41 is parallel to the horizontal second direction.

[0052] In this embodiment, the tilting mechanism 4 also includes a third gear mechanism 410 to further reduce speed. The first gear mechanism 42, the second gear mechanism 43, and the third gear mechanism 410 each include a driving gear and a driven gear. The third gear mechanism 410 and the second gear mechanism 43 also include an intermediate gear, through which the driving gear and the driven gear mesh. The first gear mechanism 42 is a helical cylindrical gear mechanism, with its driving gear and driven gear meshingly connected.

[0053] The driving gear of the third gear mechanism 410 is connected to the output shaft 12, while the driven gear and the driving gear of the first gear mechanism 42 are connected to the same rotating shaft. The driven gear and thumbwheel 45 of the first gear mechanism 42 are both 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. 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 sequentially transmits power to the third gear mechanism 410, the first gear mechanism 42, the combined Maltese wheel 44 and thumbwheel 45, the second gear mechanism 43, and the flip member 41. The coordination of the Maltese wheel 44 and thumbwheel 45 enables intermittent motion of the second gear mechanism 43, the third rotating shaft 420, and the flip member 41, thereby coordinating the movements of the lifting member 21 and the swinging member 31.

[0054] The flipping mechanism 4 also includes a handwheel 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, namely the driving pulley, is directly connected to the handwheel 46 or connected to the handwheel 46 via a rotating shaft, and the output end, namely the driven pulley, is connected to the first rotating shaft 48. In other words, 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 operating, the handwheel 46 is turned, and power is transmitted to the flipping member 41 through the second belt transmission mechanism 47, so that the phase of the Maltese wheel 44 can be adjusted during the commissioning of the flipping device.

[0055] The flipping mechanism 4 also includes a negative pressure member 49. The flipping member 41 is provided with suction holes, which face the cigarette pack 100. The negative pressure member 49 and the flipping member 41 are connected, so that the flipping member 41 vacuum-adsorbs the cigarette pack 100. For example, or optionally, the flipping member 41 includes a central connecting portion and four flaps, which are cross-connected to the periphery of the central connecting portion. The central connecting portion is connected to a third rotating shaft 420. The third rotating shaft 420 rotates to enable different flaps to flip the cigarette pack 100. The negative pressure member 49 includes a negative pressure tube and a control disk 430. Negative pressure is maintained in the negative pressure tube, which is connected to the flipping member 41 via the control disk 430 to prevent the cigarette pack 100 from being dislodged during rotation. 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 are separated, and the cigarette pack 100 is prevented from continuing to rotate with the flip member 41. The specific structure of the control disk 430 refers to the existing technology 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 achieved 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, with both the drive mechanism 1 and the safety mechanism 5 being communicatively connected to the monitoring system. When the lifting member 21 lifts the cigarette pack 100, causing it to shift to a first predetermined position, the safety mechanism 5 is triggered, which then feeds a signal back to the monitoring system. By providing the safety mechanism 5, when triggered during the lifting process, the position of the cigarette pack 100 shifts. This signals the monitoring system, which then stops the drive mechanism 1, preventing damage to the flipping device components caused by pack jamming and 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. One end of each baffle 53 is rotatably connected to the carrier 54, and the other end is connected to the carrier 54 via two tension springs 52. For example, the carrier 54 is provided with an avoidance hole 541, and the two baffles 53 are both located at the avoidance hole 541. When the lifting member 21 lifts the cigarette pack 100 through the avoidance hole 541 to the first preset position, the cigarette pack 100 can touch the baffle 53 when it deviates. The detector 51 detects the touched baffle 53 and feeds back a signal to the monitoring system. When the cigarette pack 100 touches any baffle 53 during the lifting process, it is triggered. The area enclosed by the baffles 53 is the first preset position, that is, the position of the cigarette pack 100 is limited by the baffles 53. Detector 51 is a distance sensor. The rotational centerlines of the two baffles 53 are parallel to each other, allowing them to rotate toward or away from each other. When baffles 53 rotate, the distance between them changes, and detector 51 detects a pack jam, preventing forced operation of the flipping device and mechanical damage to the transmission components. A tension spring 52 is provided to automatically reset baffles 53 when a cigarette pack 100 is removed.
