Description

Technical Field

[0001] This utility model relates to a cigarette pack positioning device, and more particularly to a four-position cigarette pack positioning device for a cigarette pack output turntable. Background Technology

[0002] Currently, the association between the "box" and "bar" QR codes is completed by a processor after sampling by a QR code camera. The "box" QR code camera is located at station four of the YB55 machine's output turntable. Station four is mainly responsible for: 1. Conveying cigarette packs; 2. Replenishing cigarette packs from the pack storage to empty slots on the conveyor turntable after rejecting defective packs at station three; 3. Taking photos of the "box" QR code. The YB55 machine's output turntable device has eight mold boxes, each mold box slot consisting of two individual mold boxes. Turntable walls are installed on the sides of the mold boxes at stations two to four to prevent cigarette packs from being thrown off the output turntable. Since station three is the rejection station for defective cigarette packs, the rejection base plate is located below the mold box at station three. During normal cigarette pack conveying, the rejection base plate supports the cigarette packs. When a cigarette pack needs to be rejected, the rejection base plate rotates 45° to create space, and the cigarette pack is rejected under its own weight. Therefore, sufficient distance must be maintained between the turntable wall and the cigarette packs to prevent pack rejection issues due to insufficient space. During daily production, the equipment operates at a relatively high speed, and the output turntable moves intermittently. The cigarette packs constantly switch between high-speed movement and stationary states. Under centrifugal force, the cigarette packs are thrown against the turntable wall on the side of the mold box. After collision, they rebound. The rebound of the cigarette packs is constrained by their position in both the circumferential and radial directions. This can cause issues such as QR code reflection and blurry photos in the QR code camera due to the different positions and angles of the cigarette packs. This seriously affects the effective operating rate of the equipment and increases unnecessary labor and material consumption. Utility Model Content

[0003] The purpose of this invention is to provide a four-position cigarette pack positioning device for a cigarette pack output turntable to solve the technical problems in the prior art. It can limit the position of the cigarette pack, thereby ensuring that the QR code can be clearly captured.

[0004] This utility model provides a four-position cigarette pack positioning device for a cigarette pack output turntable, including a turntable, a base plate, and a turntable arm. The base plate is disposed on the outer side of the turntable and extends from the first position to the fifth position. The turntable arm is fixed on the outer edge of the base plate and is used to block the second, third, and fourth positions. A guide rod single-acting cylinder is disposed on the turntable arm at the fourth position and is connected to a control device.

[0005] In the aforementioned four-position cigarette pack positioning device for the cigarette pack output turntable, preferably, the control device includes a relay, a pneumatic solenoid valve, and a PLC controller. The relay is electrically connected to the pneumatic solenoid valve and the PLC controller. The pneumatic solenoid valve is connected to the air source and the single-acting cylinder of the guide rod through an air pipe.

[0006] In the aforementioned four-position cigarette pack positioning device for the cigarette pack output turntable, preferably, the relay, the pneumatic solenoid valve, and the PLC controller are all installed in the electrical control cabinet.

[0007] In the aforementioned four-station cigarette pack positioning device for the cigarette pack output turntable, preferably, the PLC controller is also electrically connected to the YB55 encoder on the packaging machine.

[0008] In the aforementioned four-position cigarette pack positioning device for the cigarette pack output turntable, preferably, the single-acting cylinder of the guide rod is fixed on the outer wall of the turntable arm and located at the center position in the height direction of the turntable arm, and the turntable arm is provided with a clearance hole for the piston rod of the single-acting cylinder of the guide rod to pass through.

[0009] In the aforementioned four-position cigarette pack positioning device for the cigarette pack output turntable, preferably, the end of the piston rod of the single-acting cylinder of the guide rod is flush with the inner wall of the turntable arm in the retracted state.

[0010] Compared with existing technologies, this utility model includes a turntable, a base plate, and a turntable arm. The base plate is located on the outer side of the turntable and extends from the first workstation to the fourth workstation. The turntable arm is fixed to the outer edge of the base plate and is used to shield the second, third, and fourth workstations. A guide rod single-acting cylinder is installed on the turntable arm at the fourth workstation, and the guide rod single-acting cylinder is connected to a control device. This utility model, by installing a guide rod single-acting cylinder at the fourth workstation, can push the cigarette packs within the fourth workstation, causing them to abut against the inner wall of the mold box.

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0015] Embodiments of this utility model: such as Figures 1-2 As shown, a four-station cigarette pack positioning device for a cigarette pack output turntable includes a turntable 1, a base plate 2, and a turntable arm 3. Eight mold boxes 9 are fixedly installed on the turntable 1 at equal intervals along its circumference. A mold box slot is formed between two adjacent mold boxes 9. The mold box slot is used to accommodate cigarette packs 11. One mold box slot is one station. The base plate 2 is located on the outside of the turntable 1 and extends from the first station to the fifth station. The turntable arm 3 is fixed on the outer edge of the base plate 2. The turntable arm 3 is used to block the second, third, and fourth stations. A guide rod single-acting cylinder 4 is installed on the turntable arm 3 at the fourth station. The guide rod single-acting cylinder 4 is connected to a control device.

[0016] In this embodiment, the first workstation is located at the twelve o'clock position, and the workstations in the counterclockwise direction starting from the first workstation are the second workstation, the third workstation, the fourth workstation, the fifth workstation, the sixth workstation, the seventh workstation, and the eighth workstation.

[0017] A cigarette pack rejection base plate 10 is provided on the base plate 2. The cigarette pack rejection base plate 10 is located below the third station. When the cigarette packs 11 are being conveyed normally, the cigarette pack rejection base plate 10 supports the cigarette packs 11. When it is necessary to reject the cigarette packs 11, the rejection base plate rotates 45° to make room, and the cigarette packs 11 slide down under their own weight. The cigarette pack rejection base plate 10 is an existing structure, and the specific structure and working principle of the cigarette pack rejection base plate 10 will not be described in detail in this embodiment.

[0018] When the cigarette pack 11 moves to the fourth position, the control device controls the cylinder rod of the single-acting cylinder 4 to extend. The cylinder rod pushes the cigarette pack 11, so that the cigarette pack 11 abuts against the inner side wall 12 of the two mold boxes 9. At this time, the position of the cigarette pack 11 is corrected, which solves the problem of QR code reflection caused by the incorrect position of the cigarette pack. The camera takes a picture of the QR code to ensure the clarity of the captured image.

[0019] Furthermore, the control device includes a relay 5, a pneumatic solenoid valve 6, and a PLC controller 7. The relay 5 is electrically connected to the pneumatic solenoid valve 6 and the PLC controller 7. The pneumatic solenoid valve 6 is connected to the air source and the single-acting cylinder 4 with the guide rod via an air pipe.

[0020] In this embodiment, relay 5, pneumatic solenoid valve 6, and PLC controller 7 are all installed inside the electrical control cabinet. The electrical control cabinet can protect relay 5, pneumatic solenoid valve 6, and PLC controller 7 from damage.

[0021] The preferred model of PLC controller 7 is Siemens S7-1200. PLC controller 7 is connected to YB55 encoder 8 on the packaging machine. Relay 5 is connected to PLC controller 7. PLC controller 7 sends control signals to relay 5 according to the signals from YB55 encoder 8. After receiving the signal, the normally open contact of relay 5 closes, the pneumatic solenoid valve 6 is activated, and the compressed air in the air pipe causes the single-acting cylinder 4 of the guide rod to move the cigarette pack towards the inner wall 12 of the mold box.

[0022] Preferably, the single-acting cylinder 4 is fixed on the outer wall of the turntable arm 3 and located at the center of the height direction of the turntable arm 3. The turntable arm 3 is provided with a clearance hole for the piston rod of the single-acting cylinder 4 to pass through.

[0023] In the retracted state, the piston rod of the single-acting cylinder 4 does not extend beyond the inner wall of the turntable arm 3. In this embodiment, the end is preferably flush with the inner wall of the turntable arm 3. The maximum stroke of the piston rod of the single-acting cylinder 4 is 15mm. When the piston rod extends to its maximum stroke, the distance between the end of the piston rod and the inner wall 12 of the mold box is the width of the cigarette pack + 2mm. This design ensures that the cigarette pack 11 moves to the standard position while preventing the piston rod from squeezing the cigarette pack 11 and causing defects on its surface.

[0024] The working principle of this utility model is as follows: During operation, the YB55 encoder 8 sends the running phase of the turntable 1 to the PLC controller 7. When the cigarette pack 11 moves to the fourth position under the drive of the mold box 9, the PLC controller 7 sends a signal to the relay 5. The coil of the relay 5 is energized, the normally open contact closes, and the pneumatic solenoid valve 6 is turned on. Compressed air enters the guide rod single-acting cylinder 4 through the air pipe. The piston of the guide rod single-acting cylinder 4 extends outward under the push of the compressed air, pushing the cigarette pack 11 to move towards the inner wall 12 of the mold box. The QR code camera completes the sampling of the QR code of the "box" through the photo hole. At this time, the output turntable 1 is in a paused state. After the photo is taken, the PLC controller 7 controls the coil of the relay 5 to be de-energized, the normally open contact of the relay 5 opens, the pneumatic solenoid valve 6 is de-energized and closes the air pipe, and the guide rod single-acting cylinder 4 retracts and resets under the action of its own reset spring force.

[0025] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
