Description

Technical Field

[0001] The present invention relates to the technical field of conveying, and in particular to a tobacco rod conveying system and a conveying method. Background Art

[0002] During the packing process of cigarette cartons, the cigarette cartons will be transported from the upstream equipment to the appearance quality inspection station or other stations, and will flow into the next process after passing the inspection. Figure 1 As shown, the existing packaging equipment does not have a cigarette strip conveying system. When the cigarette strip conveying channel of the downstream machine is blocked or has other faults, the cigarette strip conveying chain will stop conveying. When the upstream machine equipment detects that the cigarette strip conveying chain is blocked, it will force the packaging machine's cigarette strip line to stop production. During the fault handling period, the upstream machine equipment can only stop production, which seriously affects the production efficiency of the packaging equipment.

[0003] Therefore, it is necessary to design a tobacco rod conveying system, which can discharge the tobacco rods from the conveying system when the downstream machine tobacco rod conveying chain stops conveying, and arrange the tobacco rods in a regular pattern to facilitate packing by other equipment or manual packing. Summary of the invention

[0004] The object of the present invention is to provide a tobacco rod conveying system and method, so as to solve the problem that when the downstream machine tobacco rod conveying chain stops conveying, the tobacco rods can be discharged from the conveying system, thereby avoiding affecting the production efficiency of the packaging equipment.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A tobacco rod conveying system comprises an upstream conveyor and a tobacco rod conveying channel, wherein the tobacco rod conveying channel is arranged at the end of the upstream conveyor, and further comprises a tobacco rod reversing channel, wherein the tobacco rod reversing channel is arranged at one side of the tobacco rod conveying channel, and a lifting and translation mechanism is arranged at the top of the tobacco rod conveying channel;

[0007] The lifting and translation mechanism comprises a lifting and translation support, a wall panel and a conveyor belt assembly. The wall panel is fixedly arranged between the end of the upstream conveyor and the upper port of the tobacco rod reversing channel. The lifting and translation support is telescopically connected to the wall panel. A plurality of lifting guide wheels are rotatably arranged below the lifting and translation support. The conveyor belt assembly is arranged on the wall panel. A storage baffle is arranged on one side of the lifting and translation support. The lifting guide wheel corresponds to the conveyor belt assembly.

[0008] When the lifting and translating bracket is fully extended, the entry baffle blocks the upper port of the tobacco rod reversing channel and the lifting guide wheel is located outside the tobacco rod conveying channel. When the lifting and translating bracket is fully retracted, the entry baffle is located outside the upper port of the tobacco rod reversing channel and the lifting guide wheel is located in the tobacco rod conveying channel.

[0009] Furthermore, a cylinder seat is arranged on the wall panel, a first cylinder is arranged on the cylinder seat, and a push-out end of the first cylinder is connected to the lifting and translation bracket.

[0010] Furthermore, the lifting and translation bracket is L-shaped and is provided with reinforcing ribs, a triangular bracket is provided on one side of the lifting and translation bracket, the triangular bracket is parallel to the wall panel and the lifting guide wheel is provided on the triangular bracket, and a warehouse entry baffle is provided on the other side of the lifting and translation bracket, and the warehouse entry baffle is perpendicular to the wall panel.

[0011] Furthermore, the conveyor belt assembly includes a first transmission pulley, a second transmission pulley, a motor and a conveyor belt. The first transmission pulley and the second transmission pulley are rotatably arranged on the wall panel and a conveyor belt is wound around the first transmission pulley and the second transmission pulley. A motor and a tensioning adjustment device are arranged on the wall panel. The motor is drivingly connected to the first transmission pulley, and the tensioning adjustment device is connected to the second transmission pulley.

[0012] Furthermore, the tobacco rod reversing channel includes a first turning channel, a vertical falling channel and a second turning channel. The vertical surface of the first turning channel is perpendicular to the vertical surface of the second turning channel. The bottom surface of the first turning channel is an arc surface and the outer side is a right-angle structure. The first turning channel is fixedly arranged on the top of the vertical falling channel and the first turning channel is connected to the top of the tobacco rod conveying channel. The second turning channel is an arc trough structure and is fixedly connected to the bottom of the vertical falling channel.

[0013] Furthermore, a vertical deceleration brush is provided on one side of the vertical falling channel, the brush head of the vertical deceleration brush extends into the vertical falling channel, and the gap between the brush head of the vertical deceleration brush and the other side of the vertical falling channel is smaller than the thickness of the tobacco rod.

[0014] Furthermore, it also includes a tobacco rod sorting platform, on which is provided a horizontal push sorting mechanism for pushing out and sorting tobacco rods that have slipped out of the tobacco rod reversing channel, and the horizontal push sorting mechanism is arranged at the bottom of the second turning channel.

[0015] Furthermore, the horizontal push sorting mechanism includes a second cylinder, a horizontal positioning baffle, a cigarette rod in place baffle, a horizontal deceleration brush bracket and a longitudinal deceleration brush bracket. The second cylinder is fixedly arranged on the cigarette rod sorting platform and is connected to a horizontal push guide plate at the pushing end of the second cylinder. The horizontal push guide plate is L-shaped. The horizontal deceleration brush bracket and the longitudinal deceleration brush bracket are both arranged on both sides of the second cylinder, wherein a horizontal deceleration brush is arranged on the horizontal deceleration brush bracket, and a longitudinal deceleration brush is arranged on the longitudinal deceleration brush bracket; the horizontal positioning baffle and the cigarette rod in place baffle are respectively arranged on both sides of the second cylinder; wherein, when the second cylinder is in an initial state, the long side of the horizontal push guide plate is flush with the horizontal positioning baffle to form a sorting surface, and the sorting surface is flush with a side surface of the bottom end of the second turning channel, and a cigarette rod in place detection sensor is arranged on the cigarette rod in place baffle.

[0016] Furthermore, the transverse deceleration brush is a cylindrical brush and is connected to a transverse deceleration brush bracket via a screw, and the longitudinal deceleration brush is a strip brush.

[0017] In addition, based on a tobacco rod conveying system, the present invention also provides a tobacco rod conveying method, and the specific steps are as follows:

[0018] Step 1: When the downstream equipment is operating normally, the control system sends a signal to control the solenoid valve to close, and the first cylinder extends so that the lifting translation bracket is in a fully extended state. At this time, the warehouse baffle blocks the port of the first turning channel and the lifting guide wheel is located outside the tobacco rod conveying channel, so that the tobacco rod conveying channel is opened and the tobacco rod reversing channel is closed, and the tobacco rods are conveyed from the upstream conveyor to the tobacco rod conveying channel;

[0019] Step 2: When the tobacco rod is transported to the end of the upstream conveyor, one side of the tobacco rod is transported forward by the conveyor belt. Since the other side is not supported by the conveyor belt, the tobacco rod is turned over by gravity and falls into the tobacco rod conveying channel. The tobacco rod falls from the tobacco rod conveying channel and enters the appearance quality inspection station. After the appearance quality inspection is qualified, it flows into the next station.

[0020] Step 3, when the downstream equipment stops, after the control system receives the downstream equipment stop signal, if there are cigarette rods in the cigarette rod conveying channel, it waits for the cigarette rods to fall until the appearance quality inspection station completes the inspection and there is no signal. At this time, the control system sends a signal to control the solenoid valve to disconnect, and the first cylinder retracts so that the lifting and translational support is in a fully retracted state;

[0021] Step 4: When the lifting and translational support is fully retracted, the lifting guide wheel and the warehouse entry baffle move backward with the lifting and translational support, so that the lifting guide wheel blocks the tobacco rod conveying channel and the tobacco rod reversing channel is opened, and the tobacco rods on the upstream conveyor pass through the bridge formed by the lifting guide wheel and the conveyor belt and enter the tobacco rod reversing channel;

[0022] Step 5: In the cigarette rod reversing channel, the cigarette rod passes through the first turning channel and changes from a horizontal state to a vertical state, falls into the vertical falling channel and is decelerated by a vertical deceleration brush, and when it flows out of the second turning channel, the cigarette rod is in a sideways state and enters the horizontal push finishing mechanism;

[0023] Step 6: The cigarette rods arrive at the horizontal push arrangement mechanism. When the cigarette rod arrival detection sensor detects the arrival of the cigarette rods, the control system sends a signal to control the solenoid valve to close, the second cylinder pushes out, and the horizontal push guide plate retracts immediately after pushing out the cigarette rods, completing the neat pushing and arranging of the cigarette rods.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention is provided with a tobacco rod conveying channel and a tobacco rod reversing channel at the end of the upstream conveyor. When the downstream machine tobacco rod conveying chain plate stops conveying, the tobacco rod reversing channel can be used to convey the tobacco rod, so that there is no need to stop production. A lifting translation mechanism is provided above the tobacco rod conveying channel and the tobacco rod reversing channel. In the mechanism, the pushing out and retraction of the lifting translation bracket are controlled by the first cylinder, so as to switch the tobacco rod conveying channel and the tobacco rod reversing channel. When the lifting translation bracket is extended, the warehouse baffle blocks the tobacco rod reversing channel, and the cigarette rods fall into the tobacco rod conveying channel through the conveyor belt. When the lifting translation bracket is retracted, the conveyor belt and the lifting guide wheel form a bridge to convey the cigarette rods to the tobacco rod reversing channel. In this way, the switching and conveying of the cigarette rods is realized, and the shutdown that affects the packaging efficiency is avoided.

[0026] The cigarette rod reversing channel is designed as a three-section structure of a first reversing channel, a second reversing channel and a vertical falling channel, which can realize the reversal of the cigarette rods to facilitate the subsequent sorting process of the cigarette rods;

[0027] A flat push sorting mechanism is provided at the bottom of the cigarette rod reversing channel, which can arrange the cigarette rods neatly, thus facilitating the subsequent packing process. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the tobacco rod conveying channel 5 is opened and the tobacco rod reversing channel 2 is closed, and the tobacco rods are conveyed from the tobacco rod conveying channel 5. This process is performed when the downstream equipment is operating normally. Figure 6 As shown, when the lifting and translational bracket 15 is fully retracted, the entry baffle 15c is located outside the upper end of the tobacco rod reversing channel 2 and the lifting guide wheel 16 is located in the tobacco rod conveying channel 5. At this time, the tobacco rod conveying channel 5 is closed and the tobacco rod reversing channel 2 is opened, and the tobacco rods are conveyed from the tobacco rod reversing channel 2. This process is performed when the downstream equipment stops due to a fault.

[0043] Optionally, in this embodiment, in order to allow the lifting and translational bracket 15 to be retractable, a cylinder seat 12 is provided on the wall panel 14 , a first cylinder 11 is provided on the cylinder seat 12 , and an ejection end of the first cylinder 11 is connected to the lifting and translational bracket 15 .

[0044] In actual use, the front and rear ends of the first cylinder 11 are respectively connected to the first air pipe and the second air pipe, the first air pipe and the second air pipe are connected to the air source via a solenoid valve, and the solenoid valve of the cylinder is controlled by a PLC controller.

[0046] More specifically, the conveyor belt assembly includes a first transmission pulley 18, a second transmission pulley 19, a motor 13 and a conveyor belt 17, wherein the first transmission pulley 18 and the second transmission pulley 19 are rotatably arranged on the wall panel 14 and the conveyor belt 17 is wound around the first transmission pulley 18 and the second transmission pulley 19, and the motor 13 and the tension adjustment device 19a are arranged on the wall panel 14, the motor 13 is drivingly connected to the first transmission pulley 18, and the tension adjustment device 19a is connected to the second transmission pulley 19. Preferably, the width of the conveyor belt 17 is 1 / 3 of the width of the tobacco rod, so as to prevent the tobacco rod from being transported to the tobacco rod reversing channel 2 through the conveyor belt 17 when the lifting and translation bracket 15 is fully extended, and the conveyor belt 17 is designed to be narrower, so that when one side of the tobacco rod is on the conveyor belt 17, the tobacco rod will fall into the tobacco rod conveying channel 5 due to the small contact surface with the tobacco rod due to gravity.

[0047] refer to Figure 7-8 As shown, in this actual embodiment, the tobacco rod reversing channel 2 includes a first turning channel 21, a vertical falling channel 23 and a second turning channel 22. In order to make the tobacco rod reverse in the tobacco rod reversing channel 2, the vertical surface of the first turning channel 21 is perpendicular to the vertical surface of the second turning channel 22. The bottom surface of the first turning channel 21 is an arc surface and the outer side is a right-angle structure so that it can fall into the vertical falling channel 23. The first turning channel 21 is fixedly arranged at the top of the vertical falling channel 23 and the first turning channel 21 is connected to the top of the tobacco rod conveying channel 5. The second turning channel 22 is an arc trough structure and is fixedly connected to the bottom of the vertical falling channel 23.

[0048] In actual use, the tobacco rods are in a flat state when passing through the upstream conveyor 4, in a vertical state when passing through the arc bottom surface of the first turning channel 21, and in a sideways state when passing through the second turning channel 22.

[0049] Furthermore, a vertical deceleration brush 24 is provided on one side of the vertical falling channel 23, the brush head of the vertical deceleration brush 24 extends into the vertical falling channel 23, and the gap between the brush head of the vertical deceleration brush 24 and the other side of the vertical falling channel 23 is smaller than the thickness of the tobacco rod.

[0051] The tobacco rod conveying system further comprises a tobacco rod arranging platform 35, on which a flat push arranging mechanism 3 is arranged for pushing out and arranging the tobacco rods that have fallen out of the tobacco rod reversing channel 2. Fig. 9As shown, the horizontal push sorting mechanism 3 is arranged at the bottom of the second turning channel 22.

[0052] For more details, please refer to Fig.10 As shown, the flat push sorting mechanism 3 includes a second cylinder 31, a horizontal positioning baffle 32, a cigarette rod in place baffle 33, a horizontal deceleration brush bracket 37 and a longitudinal deceleration brush bracket 39. The second cylinder 31 is fixedly arranged on the cigarette rod sorting platform 42 and a flat push guide plate 36 is connected to the push-out end of the second cylinder 31. Similarly, the front and rear ends of the second cylinder 31 are respectively connected to the first air pipe and the second air pipe.

[0054] In addition, the present invention also provides a method for conveying cigarette rods in different lanes, and the specific steps are as follows:

[0055] Step 1: When the downstream equipment is operating normally, the control system sends a signal to control the solenoid valve to close, and the first cylinder 11 extends so that the lifting translation bracket 15 is in a fully extended state. At this time, the entry baffle 15c blocks the port of the first turning channel 21 and the lifting guide wheel 16 is located outside the tobacco rod conveying channel 5, so that the tobacco rod conveying channel 5 is opened and the tobacco rod reversing channel 2 is closed, and the tobacco rods are conveyed from the upstream conveyor 4 to the tobacco rod conveying channel 5;

[0056] Step 2: When the tobacco rod is transported to the end of the upstream conveyor 4, one side of the tobacco rod is transported forward by the conveyor belt 17. Since the other side is not supported by the conveyor belt 17, the tobacco rod is turned over by gravity and falls into the tobacco rod conveying channel 5. The tobacco rod falls from the tobacco rod conveying channel 5 and enters the appearance quality inspection station. After the appearance quality inspection is qualified, it flows into the next station.

[0057] Step 3, when the downstream equipment stops, after the control system receives the downstream equipment stop signal, if there are tobacco rods in the tobacco rod conveying channel 5, it waits for the tobacco rods to fall until the appearance quality inspection station completes the inspection and there is no signal. At this time, the control system sends a signal to control the solenoid valve to be disconnected, and the first cylinder 11 retracts so that the lifting and translational support 15 is in a fully retracted state;

[0058] Step 4: When the lifting and translational support 15 is fully retracted, the lifting guide wheel 16 and the entry baffle 15c move backwards along with the lifting and translational support 15, so that the lifting guide wheel 16 blocks the tobacco rod conveying channel 5 and the tobacco rod reversing channel 2 is opened, and the tobacco rods on the upstream conveyor 4 pass through the bridge formed by the lifting guide wheel 16 and the conveyor belt 17 and enter the tobacco rod reversing channel 2;

[0059] Step 5: In the cigarette rod reversing channel 2, the cigarette rod passes through the first turning channel 21 and changes from a horizontal state to a vertical state, falls into the vertical falling channel 23 and is decelerated by the vertical deceleration brush 24, and when it flows out of the second turning channel 22, the cigarette rod is in a sideways state and enters the horizontal push finishing mechanism 3;

[0060] Step 6, the cigarette rods arrive at the horizontal push arrangement mechanism 3. When the cigarette rod arrival detection sensor 34 detects the arrival of the cigarette rods, the control system sends a signal to control the solenoid valve to close, the second cylinder 31 pushes out, and the horizontal push guide plate 36 retracts immediately after pushing out the cigarette rods, completing the neat pushing and arranging of the cigarette rods.

9. A tobacco rod conveying system according to claim 8, characterized in that: The transverse deceleration brush (38) is a cylindrical brush and is connected to the transverse deceleration brush bracket (37) via a screw, and the longitudinal deceleration brush (310) is a strip-shaped brush.

10. A method for conveying cigarette rods in separate lanes, based on a cigarette rod conveying system in separate lanes as claimed in any one of claims 1 to 9, characterized in that: The specific steps are as follows: Step 1: When the downstream equipment is operating normally, the control system sends a signal to control the solenoid valve to close, and the first cylinder (11) extends so that the lifting translation bracket (15) is in a fully extended state. At this time, the entry baffle (15c) blocks the port of the first turning channel (21) and the lifting guide wheel (16) is located outside the tobacco rod conveying channel (5), so that the tobacco rod conveying channel (5) is opened and the tobacco rod reversing channel (2) is closed, and the tobacco rods are conveyed from the upstream conveyor (4) to the tobacco rod conveying channel (5); Step 2: When the tobacco rod is transported to the end of the upstream conveyor (4), one side of the tobacco rod is transported forward under the action of the conveyor belt (17). Since the other side is not supported by the conveyor belt (17), the tobacco rod is turned over under the action of gravity and falls into the tobacco rod conveying channel (5). The tobacco rod falls from the tobacco rod conveying channel (5) and enters the appearance quality inspection station. After passing the appearance quality inspection, it flows into the next station. Step 3, when the downstream equipment stops, after the control system receives the downstream equipment stop signal, if there are tobacco rods in the tobacco rod conveying channel (5), the control system waits for the tobacco rods to fall until the appearance quality inspection station completes the inspection and there is no signal. At this time, the control system sends a signal to control the electromagnetic valve to disconnect, and the first cylinder (11) retracts so that the lifting and translational support (15) is in a fully retracted state; Step 4: When the lifting and translational support (15) is fully retracted, the lifting guide wheel (16) and the warehouse entry baffle (15c) move backwards along with the lifting and translational support (15), so that the lifting guide wheel (16) blocks the tobacco rod conveying channel (5) and the tobacco rod reversing channel (2) is opened, and the tobacco rods on the upstream conveyor (4) pass through the bridge formed by the lifting guide wheel (16) and the conveyor belt (17) and enter the tobacco rod reversing channel (2); Step 5: In the cigarette rod reversing channel (2), the cigarette rod passes through the first turning channel (21) to change from a horizontal state to a vertical state, falls into the vertical falling channel (23) and is decelerated by the vertical deceleration brush (24), and when it flows out of the second turning channel (22), the cigarette rod is in a sideways state and enters the horizontal push finishing mechanism (3); Step 6: The cigarette rods arrive at the horizontal push arrangement mechanism (3). When the cigarette rod arrival detection sensor (34) detects the arrival of the cigarette rods, the control system sends a signal to control the electromagnetic valve to close, the second cylinder (31) pushes out, and the horizontal push guide plate (36) retracts immediately after pushing out the cigarette rods, completing the neat pushing and arranging of the cigarette rods.
