Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco processing, and more specifically, to a support device for a cigarette detector and a cigarette making machine. Background Art
[0002] As Figure 1 shown, a cigarette making and forming machine includes a conveying device (optionally a guide rail) for conveying cigarettes and a feed drum 10 provided at the downstream end of the conveying device. A plurality of wheel grooves 20 are arranged on the outer peripheral surface of the feed drum 10 along its circumferential direction. The cigarette making and forming machine further includes an ejector wheel which is rotatably arranged to eject the cigarettes 30 on the conveying device into the wheel grooves 20 of the feed drum 10. The feed drum 10 is rotatably arranged so that the plurality of circumferentially arranged wheel grooves sequentially receive the cigarettes 30 from the conveying device. A positioning block 40 for restricting the position of the cigarette 30 entering the wheel groove 20 is provided in each wheel groove 20.
[0003] The single-length cigarettes 30 on the diamond-shaped guide rail of the cigarette making and forming machine are conveyed by the ejector wheel to the wheel grooves of the feed drum 10 of the filter rod splicer. There is a positioning block 40 on each wheel groove. Each wheel groove of the feed drum only receives one single-length cigarette, which is positioned by the positioning block, and the single-length cigarettes are arranged in a staggered manner on the feed drum 10. A pulse detector 60 on a bracket 50 above the feed drum 10 detects the single-length cigarettes 30. The pulse detector 60 is fixed by a detector bracket to the upper right of the feed drum 10. When the internal and external detectors continuously detect the loss of 3 pulses, the shutdown procedure is started.
[0004] The existing detector bracket 50 has only one set of detector mounting holes and cannot axially adjust the position of the detector 60. When the length specification of the cigarette 30 changes and the length of the cigarette becomes shorter, the detector cannot detect the cigarette, resulting in equipment shutdown.
[0005] Refer to Figure 2 , the detection direction of the existing detector bracket 50 is perpendicular to the surface of the drum 10 and the angle of the detector 60 cannot be adjusted. When the diameter of the cigarette 30 is 7.8 mm, the output pulse wave is a normal detection wave of a cycle of 3 rising edges plus 1 falling edge (see Figure 3 ).
[0006] Refer to Figure 4 , when the diameter of the cigarette 30 becomes smaller, the cigarette 30 cannot fill the wheel groove 20, and the infrared ray emitted by the detector 60 first falls on the bottom of the wheel groove 20 and then the cigarette 30 can be detected, resulting in the disorder of the detection wave and causing equipment shutdown. Figure 5 shows a disordered detection wave. Summary of the Utility Model

[0045] As Figure 6As shown, the cigarette making and forming machine includes a conveying device (optionally a guide rail 3) for conveying cigarette rods and a feeding drum 6 provided at the downstream end of the conveying device. A plurality of wheel grooves arranged along the circumferential direction are provided on the outer circumferential surface of the feeding drum 6. The cigarette making and forming machine further includes an ejector 1, which is rotatably arranged to eject the cigarette rod 2 on the conveying device into the wheel groove of the feeding drum 6. The feeding drum 6 is rotatably arranged so that the plurality of wheel grooves arranged along the circumferential direction sequentially receive the cigarette rods 2 from the conveying device. A positioning block 4 for restricting the position of the cigarette rod 2 entering the wheel groove is provided in each wheel groove.
[0046] On the diamond-shaped guide rail 3 of the cigarette making and forming machine, the single-length cigarette rod 2 is conveyed by the wheel of the ejector 1 to the wheel groove of the feeding drum 6 of the filter rod assembly machine. There is a positioning block 4 on each wheel groove. Each wheel groove of the feeding drum only receives one single-length cigarette rod, which is positioned by the positioning block, and the single-length cigarette rods are arranged staggered on the feeding drum. The pulse detector 7 above the feeding drum detects the single-length cigarette rods. The pulse detector 7 is fixed by a detector bracket to the upper right of the feeding drum 6. When the internal and external detectors continuously detect the loss of 3 pulses, the shutdown procedure is started.
[0047] Combined Figures 6 to 9 As shown, the cigarette rod detector support device of this embodiment includes a base, a bracket 5 and a detector 7.
[0048] The base is used to carry the drum 6. A plurality of wheel grooves 8 for accommodating the cigarette rod 2 are provided on the circumferential surface of the drum 6, and the wheel grooves 8 are parallel to the axial direction of the drum 6. The bracket 5 is connected to the base, and the bracket 5 is parallel to the axial direction of the drum 6 and is spaced from the outer circumferential surface of the drum 6;
[0049] The detector 7 is used to detect the cigarette rod 2 in the wheel groove 8. The detector 7 is installed on the bracket 5 and is configured such that the angle between the direction in which the detector 7 emits the detection medium and the tangent direction of the drum 6 is adjustable.
[0050] In this embodiment, the direction in which the detector 7 emits the detection medium is adjustable. After the size (such as the diameter) of the cigarette rod 2 changes and causes its position in the wheel groove 8 to change, by adjusting the direction in which the detector 7 emits the detection medium, the detector 7 can be aligned with the cigarette rod 2, improving the problem in the prior art that the cigarette rod cannot be directly detected after the diameter of the cigarette rod becomes smaller.
[0051] The bracket 5 includes a first bracket 51 and a second bracket. The first bracket 51 is installed on the base. The second bracket 52 is connected to the first bracket 51 and is configured to rotate relative to the first bracket 51 about an axis parallel to the axial direction of the drum 6 to adjust the angle between the direction in which the detector 7 emits the detection medium and the tangent direction of the drum 6.
[0052] The first bracket 51 is provided with a first connection hole 53, and the second bracket 52 is provided with a second connection hole 56. The first bracket 51 and the second bracket 52 are connected by a first threaded connector disposed in the first connection hole 53 and the second connection hole 56. One or both of the first connection hole 53 and the second connection hole 56 are arc-shaped holes extending circumferentially along an axis parallel to the axial direction of the drum 6, so as to adjust the angle between the direction in which the detector 7 emits the detection medium and the tangential direction of the drum 6.
[0053] The first bracket 51 is provided with a third connection hole 54, and the second bracket 52 is provided with a fourth connection hole 57. The first bracket 51 and the second bracket 52 are connected by a second threaded connector disposed in the third connection hole 54 and the fourth connection hole 57. The third connection hole 54 and the fourth connection hole 57 are coaxial with an axis parallel to the axial direction of the drum 6.
[0054] See Figure 7 , two threaded holes (the first connection hole 53 and the third connection hole 54 respectively) are opened on the end face of the first bracket 51 for connecting the first bracket 51 and the second bracket 52.
[0055] The second bracket 52 includes a substrate perpendicular to the axial direction of the drum 6 and a main body connected to the substrate and extending in a direction parallel to the axial direction of the drum 6. The second connection hole 56 is provided on the substrate.
[0056] The overall shape of the second bracket 52 is L-shaped. A through hole (the fourth connection hole 57) and an arc-shaped groove (the second connection hole 56) are opened on the shorter section of the second bracket 52. It is connected to the two threaded holes (the first connection hole 53 and the third connection hole 54 respectively) on the end face of the first bracket 51 by screws. The arc-shaped groove of the second bracket 52 can finely adjust the angle between the detection wave emitted by the detector 7 and the tangent of the wheel groove 8 of the incoming cigarette drum 6 so as to adjust to the optimal angle. Through experiments, when the cigarette diameter is 7.8 mm, the optimal angle of the angle between the detection wave and the tangent of the incoming cigarette drum wheel groove is 90°. When the cigarette diameter is 6.36 mm, the optimal angle of the angle between the detection wave and the tangent of the incoming cigarette drum wheel groove is 78.3°. When the cigarette diameter is 5.4 mm, the optimal angle of the angle between the detection wave and the tangent of the incoming cigarette drum wheel groove is 66.2°.
[0057] The position of the detector 7 relative to the wheel groove 8 can be adjusted circumferentially along the drum 6. Specifically, the bracket 5 includes a first bracket 51, and a strip-shaped hole 55 is provided on the first bracket 51 to adjust the relative position between the detector 7 and the wheel groove 8 in the circumferential direction of the drum 6.
[0058] There are two transverse slots (bar-shaped holes 55) directly above the first bracket 51. The slots are used to connect the first bracket 51 to the base of the carrying drum 6 of the device, and the relative position of the first bracket 51 and the device can be adjusted by using the transverse slots, so that the angle between the detection wave emitted by the detector and the tangent of the wheel groove 8 of the cigarette feeding drum 6 can be changed. By changing the angle, when the diameter of the cigarette rod becomes smaller, the detection wave of the detector will not fall on the bottom of the wheel groove, thus avoiding false detection.
[0059] The bar-shaped holes 55 extend along the circumferential direction of the drum 6 or along the direction perpendicular to the axial direction of the drum 6.
[0060] A plurality of detector mounting parts 58 arranged along the axial direction of the drum 6 are provided on the bracket 5 to adjust the position of the detector 7 along the axial direction of the drum 6. In some embodiments, the detection mounting part includes a threaded hole. Specifically, the detector mounting part 58 is provided on the second bracket 52. On a longer section of the second bracket 52, a number of neatly arranged threaded holes are provided to facilitate the adjustment of the axial position of the detector relative to the cigarette feeding drum.
[0061] The beneficial effects brought by the technical solution of this embodiment are as follows:
[0062] 1. Through the arranged threaded holes (detector mounting parts 58) of the second bracket 52, the axial position of the detector relative to the cigarette feeding drum can be adjusted to adapt to different length specifications of cigarette rods.
[0063] 2. The angle between the detection wave and the tangent of the wheel groove of the cigarette feeding drum 6 is roughly adjusted through the slots (bar-shaped holes 55) of the first bracket 51, and the angle is finely adjusted through the arc-shaped slot of the bracket 5.
[0064] According to another aspect of the present invention, a cigarette making machine is further provided. The cigarette making machine includes the above-mentioned cigarette rod detector support device.
[0065] The cigarette making machine further includes a cigarette rod conveying device and an ejector 1. The cigarette rod conveying device is arranged at one end of the drum 6 along the axial direction of the drum 6. The ejector 1 is configured to convey the cigarette rods 2 to the plurality of wheel grooves 8 on the drum 6 one by one as the drum 6 rotates.
[0066] The above are only exemplary embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
