Description

TECHNICAL FIELD

[0001] The utility model relates to a cigarette packet processing technical field, especially a cigarette packet transparent paper splicing joint rejection device and packing machine. BACKGROUND

[0002] The cigarette packing machine is used for packing cigarettes into cigarette packets and packaging the cigarette packets. Specifically, the cigarette packing machine comprises transparent paper rolls and a cutting device arranged in sequence along a conveying direction. The transparent paper rolls can release transparent paper in the rotating process. The transparent paper is cut off when passing through the cutting device. Then, the packing machine wraps the cut transparent paper outside the cigarette packet. In the actual production of the packing machine, the transparent paper on the current transparent paper roll will be connected with one end of the transparent paper on the new transparent paper roll before being used up. At this time, the connection of the two transparent paper rolls will generate a splicing joint. The splicing joint wrapped on the cigarette packet will seriously affect the quality of the cigarette packet product. Therefore, it is necessary to detect the splicing joint of the transparent paper and reject the cigarette packet with the splicing joint.

[0003] In the prior art, a detection mechanism arranged upstream of the cutting device is usually used to detect the splicing joint, and a rejection mechanism arranged downstream of the detection mechanism is used to reject the cigarette packet with the splicing joint. When the detection mechanism detects the splicing joint, the transparent paper with the splicing joint cut off by the cutting device will be wrapped on the cigarette packet. When the cigarette packet with the splicing joint runs to the rejection mechanism, the rejection mechanism will reject the cigarette packet with the splicing joint once to prevent such cigarette packet from flowing into the downstream process.

[0004] However, when the cutting device cuts the transparent paper, the splicing joint may be cut on two transparent papers, that is, the splicing joint will appear on two continuous cigarette packets. This will cause the cigarette packet with the splicing joint to flow into the downstream process without being rejected completely, thereby affecting the product qualification rate.

For those skilled in the art, the specific meaning of the above terms in the embodiments can be understood according to the specific circumstances.

[0033] In order to make the purpose, technical scheme and advantages of the utility model clearer, the embodiments of the utility model will be further described in detail below with reference to the drawings.

[0034] As shown in Figure 1 and Figure 2 The embodiments of the utility model provide a cigarette package transparent paper splicing head removing device, the removing device includes: a conveying turntable 1, a first detection unit 2, a control system 3 and a removing mechanism 4.

[0035] Specifically, a plurality of clamps 11 are arranged on the conveying turntable 1, each clamp 11 is arranged at intervals along the circumference of the conveying turntable 1, and a clamping position 12 is formed between every two adjacent clamps 11, the clamping position 12 is used for clamping the cigarette package 10, and the conveying turntable 1 can drive each cigarette package 10 clamped on the conveying turntable 1 to rotate in a first rotation direction (as indicated by the R direction in the figure) to a removing station S1. Figure 1 In some embodiments, the rotating mode of the conveying turntable 1 is intermittent rotation, that is, after rotating by a certain angle, it stops running for a period of time, and then rotates by a certain angle again, and the angle of each rotation of the conveying turntable 1 is equal, and the time of each stop is equal.

[0036] The first detection unit 2 is arranged upstream of the conveying turntable 1 along the conveying direction of the cigarette package 10, and the first detection unit 2 is used for detecting the splicing head 91 of the transparent paper 9 and outputting a first signal when the splicing head 91 of the transparent paper 9 is detected. Exemplarily, the first detection unit 2 is a high-speed camera.

[0037] The control system 3 is electrically connected with the first detection unit 2, used for receiving the first signal, and counting the number of moving stations of the splicing head 91 when the first signal is received.

[0038] The removing mechanism 4 is arranged on the removing station S1, and the removing mechanism 4 is used for removing the cigarette package 10 located on the removing station S1 and the next cigarette package 10 entering the removing station S1 in sequence when the number of moving stations reaches a preset value; wherein the preset value is the number of stations experienced by the splicing head 91 from the detection area of the first detection unit 2 to the removing station S1.

[0039] The applicant fully considers the problems of the existing cigarette transparent paper splice joint removing device, the first detection unit 2 detects the transparent paper 9, when the splice joint 91 of the transparent paper 9 passes through the first detection unit 2, the first detection unit 2 sends the signal of detecting the splice joint 91 to the control system 3, and triggers the counting of the number of moving stations of the splice joint 91 when the control system 3 receives the splice joint signal. After the number of moving stations reaches the preset value, that is, the splice joint 91 moves to the removing station S1, the control system 3 controls the removing mechanism 4 to remove the cigarette 10 located at the removing station S1, and removes the cigarette 10 clamped by the next clamping position 12 after it rotates to the removing station S1, so as to completely remove the cigarette 10 with the splice joint 91, avoid the cigarette 10 with the splice joint 91 flowing into the downstream process, and further improve the product qualification rate.

[0040] Further, the number of stations through which the transparent paper splice joint moves from the detection area of the first detection unit 2 to the removing station S1 is a preset value. After receiving the first signal, the control system 3 records the actual number of moving stations of the subsequent movement of the splice joint 91 as the number of moving stations. In this embodiment, by calculating the number of moving stations of the splice joint 91 and comparing the number of moving stations with the preset value, the time when the splice joint 91 runs to the removing station S1 can be determined. Specifically, referring to Figure 2 , the control system 3 includes a counter 31 and a processor 32, the counter 31 is used to count the number of moving stations of the splice joint 91 and send the number of moving stations to the processor 32. The processor 32 is used to compare the number of moving stations with the preset value to determine whether the splice joint 91 runs to the removing station S1. When the number of moving stations is equal to the preset value, it means that the splice joint 91 runs to the removing station S1, and at this time the control system 3 controls the removing mechanism 4 to remove the cigarette with the splice joint 91 on the removing station S1.

[0041] Further, the cigarette transparent paper splice joint removing device further comprises a second detection unit 5, the second detection unit 5 is used to detect the number of rotations of the conveying turntable 1, and send a second signal to the counter 31 when detecting that the conveying turntable 1 rotates once, and the counter 31 adds 1 to the number of moving stations every time a second signal is received. The first detection unit 2 detects the splice joint 91 of the transparent paper 9, and triggers the counting of the number of moving stations of the splice joint 91 when the control system 3 receives the splice joint signal.

[0042] In some embodiments, referring to Figure 1The second detection unit 5 is arranged outside the conveying turntable 1, and the second detection unit 5 is a proximity switch. A plurality of detection blocks 13 can be arranged on the conveying turntable 1, and the number of the detection blocks 13 is equal to the number of the clamping positions 12. Each detection block 13 is arranged along the circumferential direction of the conveying turntable 1. When the conveying turntable 1 rotates once, one detection block 13 passes through the second detection unit 5 and contacts the second detection unit 5, so as to trigger the second detection unit 5. When each detection block 13 passes through the detection area of the second detection unit 5 in turn during the rotation of the conveying turntable 1, the second detection unit 5 sends a signal to the control system 3 after detecting the detection block 13. The counter 31 increases the number of moving positions by 1 each time a signal is received. Meanwhile, the processor 32 compares the number of moving positions counted by the current counter 31 with a preset value in real time, so as to determine whether the splice 91 reaches the removing position. It should be noted that the operator can select a device and a method for detecting the number of moving positions of the splice according to actual use. The detection device and method include but are not limited to the above device and method, which can ensure the accuracy of the detection result.

[0043] When the packaging machine is working, the transparent paper 9 is first released from the transparent paper reel, and the transparent paper 9 is conveyed to the cutting device 8 along the X direction as shown in Figure 5 Before being conveyed to the cutting device 8, the transparent paper 9 passes through the first detection unit 2 arranged at the front end of the cutting device 8. When the first detection unit 2 detects the splice 91 on the transparent paper 9, the first detection unit 2 transmits a first signal of detecting the splice 91 to the control system 3. At this time, the control system 3 starts counting the number of moving positions of the splice 91 to be operated subsequently. Since the second detection unit 5 is arranged outside the conveying turntable 1, after the conveying turntable 1 rotates by a certain angle, it indicates that the splice 91 moves one position. At this time, the second detection unit 5 transmits a second signal of detecting the rotation of the conveying turntable 1 to the control system 3. The counter 31 increases the number of moving positions of the splice 91 by 1 each time a second signal is received. With the increase of the number of moving positions, the splice 91 moves towards the removing position, and the transparent paper 9 with the splice 91 is wrapped on the cigarette packet 10 during the movement of the splice 91. Subsequently, the cigarette packet 10 with the splice 91 continues to move towards the removing position S1. When the number of moving positions is equal to a preset value, it indicates that the cigarette packet 10 with the splice 91 reaches the removing position S1. At this time, the control system 3 controls the removing mechanism 4 and removes the two cigarette packets 10 currently located at the removing position S1. When the conveying turntable 1 continues to rotate by a certain angle, i.e., the number of moving positions increases by 1, at this time, the control system 3 controls the removing mechanism 4 again and removes the new two cigarette packets 10 located at the removing position S1, so as to finally complete the removal of the splice 91. When the first detection unit 2 detects the splice 91 again, the above steps are repeated to complete the removal of the splice 91.

[0044] In some embodiments, one or more than one cigarette packet 10 can be clamped on each clamping position 12, and the number of cigarette packets 10 clamped on each clamping position 12 is not limited herein, and the operator can select an appropriate number of cigarette packets 10 to be clamped according to actual production needs.

[0045] Specifically, referring to Figure 3 and Figure 4 , the rejection mechanism 4 comprises a fixed seat 41, a shielding piece 42, a driving unit and a solenoid valve.

[0046] The fixed seat 41 is arranged below the conveying turntable 1, and the conveying turntable 1 is capable of rotating relative to the fixed seat 41. The fixed seat 41 is provided with a clearance hole 411 penetrating the fixed seat along the axial direction of the conveying turntable 1, and the clearance hole 411 is located below the rejection station S1.

[0047] The shielding piece 42 is arranged on the side wall of the clearance hole 411, and the shielding piece 42 is capable of moving between a first position (as shown by the position of the shielding piece 42 in Figure 3 and a second position (as shown by the position of the shielding piece 42 in Figure 4 ). When the shielding piece 42 is located at the first position, the projection of the cigarette packet 10 on the rejection station S1 in the vertical direction is located on the shielding piece 42, and the shielding piece 42 can provide support for the cigarette packet 10 on the rejection station S1. When the shielding piece 42 is located at the second position, the projection of the cigarette packet 10 on the rejection station S1 in the vertical direction is located outside the shielding piece 42.

[0048] The driving unit (not shown in the figure) is connected to the shielding piece 42, and the driving unit is used to drive the shielding piece 42 to move between the first position and the second position. Exemplarily, the driving unit can be a pneumatic cylinder.

[0049] The solenoid valve (not shown in the figure) is electrically connected to the control system 3 and the driving unit, and the control system 3 can control the opening or closing of the solenoid valve. When the solenoid valve is opened, the solenoid valve can control the driving unit to operate.

[0050] In some embodiments, the shielding piece 42 is in the shape of “L”, and the shielding piece 42 comprises a connecting plate 421 and a shielding plate 422. The connecting plate 421 is perpendicular to the horizontal direction and is rotatably arranged on the side wall of the clearance hole 411, and the shielding plate 422 is perpendicular to the connecting plate 421. When the shielding piece 42 is rotated to the first position, the shielding plate 422 is located inside the clearance hole 411 and extends along the horizontal direction. When the shielding piece 42 is rotated to the second position, the shielding plate 422 is located outside the clearance hole 411 and extends along the vertical direction.

[0051] Specifically, the application is provided with a let-out hole 411 on the fixed seat 41, a shielding piece 42 is installed on the side wall of the let-out hole 411, the shielding piece 42 comprises a connecting plate 421 and a shielding plate 422, the shielding piece 42 is connected with a driving unit, in the embodiment, the driving unit is a gas cylinder, the shielding piece 42 is connected with the piston end of the gas cylinder, when the splicing joint 91 of the transparent paper 9 is not detected, the shielding piece 42 is kept in the first position and supports the packaged cigarette packet 10 together with the upper surface of the fixed seat 41 to move to the downstream link through the conveying turntable 1; when the splicing joint 91 of the transparent paper 9 is detected and the cigarette packet 10 with the splicing joint 91 rotates to the position above the let-out hole 411, the control system 3 controls the electromagnetic valve to open, the driving unit drives the shielding piece 42 to rotate to the second position, the let-out hole 411 is in the open and unshielded state, and the cigarette packet 10 with the splicing joint 91 falls to the waste bucket through the let-out hole 411 under the action of its own gravity, so that the cigarette packet 10 with the splicing joint 91 is removed.

[0052] Based on the same concept, as shown in Figure 1 and Figure 5 the embodiment of the utility model also provides a packaging machine, including the cigarette packet transparent paper splicing joint removing device provided by above-mentioned embodiment, and transparent paper feeding mechanism 7, cutting device 8 and processing mechanism (not shown in the drawing), transparent paper feeding mechanism 7 is located at the upstream of conveying turntable 1, and transparent paper feeding mechanism 7 is used to feed transparent paper 9, cutting device 8 is located between transparent paper feeding mechanism 7 and processing mechanism, and cutting device 8 is used to cut transparent paper 9, and processing mechanism is located between cutting device 8 and conveying turntable 1, and processing mechanism is used to wrap cut transparent paper 9 on cigarette packet 10 and heat seal cut transparent paper 9 on cigarette packet 10.Exemplarily, processing mechanism can be provided with multiple processing units, and each processing unit can be used to wrap cut transparent paper 9 on cigarette packet 10 and heat seal transparent paper 9 on cigarette packet 10.

[0053] It should be noted that since the transparent paper 9 is continuous, the prior art is not convenient to directly remove the transparent paper 9 with the splicing joint. Therefore, in the present application, the removing mechanism 4 removes the cigarette packet 10 packaged with the transparent paper splicing joint 91. Between the first detection unit 2 and the removing mechanism 4, the number of stations is certain, although the transparent paper 9 with the splicing joint 91 detected by the first detection unit 2 has not been packaged into the cigarette packet 10, but the cigarette packet 10 with the splicing joint 91 detected by the first detection unit 2 can be inferred according to the number of stations between the first detection unit 2 and the removing mechanism 4, so that the control system 3 can infer the cigarette packet 10 packaged with the transparent paper 9 with the splicing joint 91 detected by the removing mechanism 4 through station calculation, and when the cigarette packet 10 can be transported to the removing station S1.

[0054] It is to be noted that the relational terms herein, such as first and second, and the like, are used solely to distinguish one from another entity or action without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.
