Description

Technical Field

[0001] The invention relates to the technical field of cigarette production, in particular to a cigarette rod rejecting device. Background Art

[0002] At present, in the GDX1 soft pack packaging unit, because the auxiliary materials need to be replaced manually: cigarette pack transparent paper, cigarette pack pull wire, cigarette rod transparent paper, cigarette rod pull wire, there is no automatic centering and correction position mechanism, and manual self-inspection and adjustment of its position are required. Since there is no cigarette storage cabinet between the packaging auxiliary machine and the main machine, when the auxiliary materials are replaced, the main machine will stop running until the auxiliary machine is reset and started. When the above auxiliary materials are replaced and the auxiliary machine is just running, the operator will immediately start the main machine without strictly inspecting the key quality points. It may be busy with other packaging processes, which will pose a risk of quality hazards. Therefore, cigarette rod pull wire joints and transparent paper adhesive tapes often flow into the cartoning machine process. If the joints are at the bottom of the cigarette rod, the appearance imaging camera cannot recognize them, and manual re-inspection will not be able to find them, so they may flow into the finished product warehouse. As for the cigarette pack pull wire joints and cigarette pack transparent paper splicing joints, when the corresponding detection or shifting program is not eliminated, the strip box packaging process will be carried out, and the box needs to be turned over for processing.

[0003] At present, the main faults of the packaging auxiliary machine are: CT push rod obstruction, uneven positioning of the strip paper, blockage of the double-pack turret outlet transmission, and inaccurate pack filling action of the cigarette pack replenisher, which may result in the failure to completely clean up the squeezed or deformed cigarette packs. It is necessary to manually count the number of cigarette strips at the exit or tear off the side cover of the folded strip paper in front of the strip packaging conveying channel, and position it at the exit and take out 5 strips in succession for manual self-inspection to prevent defective cigarette packs from being mixed in the cigarette strips and flowing into the next process. However, the above approach will result in the marked cigarette strips being rejected in the strip conveying channel, or the auxiliary machine needs to be started repeatedly several times, so it is impossible to determine the exact position of the cigarette strips, and more cigarette strips need to be taken out in advance for verification, increasing the number of manual strip punching.

[0033] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as limiting the present invention.

[0034] Please refer to Figures 1 to 3The present invention proposes a tobacco rod removal device, which includes a substrate 1, wherein the substrate 1 is a strip-shaped plate, and its length direction is consistent with the conveying direction of the tobacco rod.

[0035] Specifically, a conveyor belt 2 is disposed above the substrate 1 to form a conveying channel for the tobacco rods; during implementation, a gap is left between the substrate 1 and the conveyor belt 2 .

[0036] The base 1 is provided with a first side plate 3 and a second side plate 4 on both sides, a rejection zone is provided on the base 1, a rejection port 5 is provided on the first side plate 3 facing the rejection zone, a baffle 6 is provided at the rejection port 5, a cylinder 7 is fixedly provided above the baffle 6; the telescopic end of the cylinder 7 is fixedly connected to the baffle 6. In this way, the cylinder 7 can control the baffle 6 to move upward, so that the rejection port is opened, and the tobacco rod is easily rejected from the rejection port.

[0037] The second side plate 4 is provided with an air nozzle 8 directly opposite to the rejecting port 5. The air nozzle 8 is located at 0.5 mm inside the second side plate 4, and the number of the air nozzles 8 is two.

[0038] In a specific implementation, the number of the conveyor belts 2 is two, and the two conveyor belts 2 are arranged in parallel along the length direction of the base 1. In this way, the stability of the conveyor belt 2 during transmission can be ensured.

[0039] As a preferred implementation, the base 1 is provided with a proximity sensor near the rejection zone. The proximity sensor is used to detect whether the tobacco rod has reached a specified position, so as to control the rejection accuracy after the tobacco rod has reached the specified position.

[0040] Furthermore, a receiving box 9 is provided on the outside of the base body 1 facing the ejection port 5; the receiving box 9 is located on the outside of the first side plate 3, and the top of the receiving box 9 is not higher than the upper surface of the base body 1. The receiving box 9 is used to collect the kicked tobacco rods.

[0041] Specifically, in order to facilitate control, the present invention has been further improved, specifically, further comprising a controller, a first electromagnetic reversing valve and a second electromagnetic reversing valve; the controller is electrically connected to the first electromagnetic reversing valve and the second electromagnetic reversing valve; the air nozzle 8 is connected to the high-pressure air source through the first electromagnetic reversing valve, and the cylinder 7 is connected to the high-pressure air source through the second electromagnetic reversing valve; the controller is used to control the cylinder 7 to drive the baffle 6 to move upward through the second electromagnetic reversing valve when performing rejection, and control the air nozzle 8 to spray air toward the tobacco rod to be rejected through the first electromagnetic reversing valve, so as to push the tobacco rod to be rejected through the rejection port 5. That is, the air pressure controls the air nozzle 8 and the cylinder 7 to reject the tobacco rod.

[0042] Furthermore, in order to facilitate accurate control of the number of cigarette rods that need to be rejected, the present invention also includes a rejection detector and a counter; the rejection detector is arranged in the rejection area to detect whether the cigarette rods are rejected; the counter is used to record the number of cigarette rods rejected. More specifically, it also includes a plurality of buttons, and the plurality of buttons are electrically connected to the controller; the plurality of buttons include a small transparent paper replacement button, a small pull-wire replacement button, a large pull-wire replacement button, a large transparent paper replacement button, and a fault location button; the controller is used to obtain the number of cigarette rods to be rejected after the button is pressed, and execute the rejection action of the corresponding number of cigarette rods according to the number of cigarette rods. The number of cigarette rods to be rejected corresponding to the replacement of auxiliary materials for each button can be pre-set, and when the button is pressed, the counter is reset.

[0043] As a preferred implementation, it further comprises a buzzer, which is electrically connected to the controller and is used to sound an alarm when the marked cigarette rod is rejected, so as to remind the operator to perform self-check.

[0044] Preferably, the controller is a PLC controller. Specifically, the first electromagnetic reversing valve is a two-position three-way electromagnetic valve, and the second electromagnetic reversing valve is a three-position five-way electromagnetic valve.

[0045] The working process of the present invention is as follows:

[0046] The existing high-pressure air of the machine is connected to the air inlet of the first electromagnetic reversing valve through an air pipe, and the air outlet of the reversing valve is connected to the air pipe nozzle 11 through a branch air pipe joint.

[0047] High-pressure air is connected to the second electromagnetic reversing valve through the air pipe, and then connected to the cylinder 7 through the air pipe. The extended end of the cylinder 7 is fixed to the upper end of the baffle 6 through a nut. The baffle 6 moves up and down through the expansion and contraction of the cylinder 7. The proximity switch is located at the bottom of the conveying channel, below the upper end of the conveying flat belt. The tobacco rod rejection detection is located on one side of the rejection plate, and can detect the number of rejected tobacco rods.

[0048] When the corresponding button is pressed, the counter and the cigarette rod rejection detection start to count cumulatively from zero, and the actual statistical counter 6 subtracts the cigarette rod rejection detection count. The actual statistical count of each corresponding button is different. When the proximity switch detects that the marked cigarette rod is in place, the second solenoid reversing valve switches direction, and the driving cylinder 7 drives the baffle 6 to move upward. When the cylinder 7 with stroke feedback feeds back the in-place information, the first solenoid reversing valve starts to switch direction, and the jet nozzle sprays air to remove the marked cigarette rod into the storage box. At the same time, the buzzer sounds for 2s to prompt the operator to perform a self-check. After the rejection action is completed, the first solenoid reversing valve starts to switch direction, disconnecting the compressed gas, and the second solenoid reversing valve switches direction, and the driving cylinder drives the baffle 6 to move downward.

[0049] When continuously removing cigarettes, the cylinder 7 stops moving after the first lift, and the first electromagnetic reversing valve normally waits for the proximity switch signal to ventilate and cut off the air. After the proximity switch counts 5 cigarette rods, the second electromagnetic reversing valve switches, and the cylinder 7 drives the baffle 6 to move downward, and the baffle returns to its initial position.

[0050] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
