Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production, and in particular relates to a cleaning device and method for a cigarette replenishing station of a cigarette pack conveying turret. Background Art

[0002] During the cigarette production process, the conveyor turret installed on the YB55 small box transparent paper packaging machine removes unqualified cigarette packs and transports qualified cigarette packs to the strip box packaging machine. Unqualified cigarette packs wrapped in transparent paper will be removed at the turret box mold removal station, and the removed cigarette packs will be replenished at the cigarette replenishment station. A photoelectric switch is installed above the cigarette replenishment station. When a non-cigarette pack is detected, the cylinder at the cigarette replenisher on one side of the cigarette replenishment station will be activated to replenish cigarette packs.

[0003] Since the rejection station rejects by opening the lower baffle, the cigarette packs automatically fall down and are rejected by their own gravity. When the cigarette packs are not square or the transparent paper is loose, the rejection may be incomplete. The existing photoelectric switch automatically replenishes the empty cigarette packs at the cigarette replenishing station. When the transparent paper of a cigarette pack is loose, it may not be detected. At this time, the cylinder continues to move to replenish the cigarette packs, causing the cigarette packs to be squeezed.

[0004] The turret box mold may be blocked by cigarette pack filling and squeezing, and the machine cannot be shut down in time, causing the clutch to get stuck and shut down. In actual production, the following problems exist: First, it takes a long time to deal with the squeezing of smoke. The process requires seven steps: opening the protective cover, handling the cylinder push plate, cleaning the channel of unqualified cigarettes, cleaning the squeezed cigarette packs with tweezers, turning the car to clean the debris, filling the channel with cigarette packs, and closing the protective cover. A skilled operator takes 20 minutes to handle it, which affects the operating efficiency of the equipment. Second, it is inconvenient for the operator to handle the squeezing of smoke. When the squeezing of smoke is serious, it is even necessary to use a screwdriver to crush the cigarette packs, or remove the fixed cover. There is a risk of damaging the turret box mold when the squeezing of smoke is blocked, which will increase the difficulty of handling, and at the same time will lead to the consumption of auxiliary materials and increase the labor intensity of the operator. Summary of the invention

[0005] In view of the defects or shortcomings in the prior art, the present invention provides a cigarette pack conveying turret cigarette squeezing and cleaning device and method, which can promptly shut down the packaging machine when an squeezing failure occurs, and facilitate the cleaning of squeezed cigarette packs, thereby reducing the labor intensity of maintenance personnel, improving maintenance efficiency, and reducing maintenance costs.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Embodiment 1 A typical implementation of the present invention is as follows Figure 1 As shown, a cigarette pack conveying turret cigarette squeezing and cleaning device comprises a conveying turret 1, which is the conveying turret on the YB55 small box transparent paper packaging machine. The conveying turret 1 is provided with a rejection station 2, and unqualified cigarette packs with transparent paper splicing joints and transparent paper wrapping will be rejected at the turret box mold rejection station 2, and the station next to the rejection station 2 is the cigarette replenishment station 3, which is used to replenish cigarette packs.

[0022] A cigarette replenishing machine is arranged on one side of the cigarette replenishing station 3, and the cigarette replenishing machine comprises a cigarette pack storage rack 4 and a cylinder 5. The cigarette pack storage rack 4 is vertically fixed on one side of the cigarette replenishing station 3, and is used to store cigarette packs to be replenished. The cylinder 5 is fixed on the bottom of the cigarette pack storage rack 4 on the side away from the cigarette replenishing station 3. The telescopic axis of the cylinder 5 is arranged opposite to the cigarette replenishing station 3, and a push plate is arranged on the telescopic axis of the cylinder 5. The cylinder 5 pushes the cigarette packs in the cigarette pack storage rack 4 into the cigarette replenishing station 3 to complete the cigarette replenishment.

[0023] like Figure 2 and Figure 3 As shown, a support plate 6 is provided on one side of the bottom of the cigarette pack storage rack 4 near the cigarette replenishment station 3. The support plate 6 is located directly above the cigarette replenishment station 3 and is vertically arranged on the cigarette pack storage rack 4. One side of the support plate 6 is rotatably connected to the cigarette pack storage rack 4 through a hinge 7, so that the support plate 6 can be rotated around the hinge 7 to expose the cigarette replenishment station 3 and clear the blockage of the cigarette replenishment station 3. One end of the support plate 6 away from the hinge 7 extends obliquely upward, so that it is convenient for the staff to rotate the support plate 6.

[0024] A brush plate 8 is fixedly connected to the bottom surface of the support plate 6. The brush plate 8 is U-shaped and a brush is arranged on the bottom surface of the brush plate 8. By arranging the brush plate 8 on the bottom surface of the support plate 6, it is possible to effectively avoid the double-layer cigarette pack from jumping when entering the cigarette replenishing station 3, thereby reducing the occurrence of blockage of the cigarette replenishing station 3. The brush plate 8 extends to the left and right sides of the cigarette replenishing station 3, covering the mold boxes on the left and right sides of the cigarette replenishing station 3, thereby preventing the cigarette pack from jumping during transportation and improving the transportation stability.

[0025] A photoelectric switch 9 is fixedly connected to the upper surface of the support plate 6. The photoelectric switch 9 is arranged opposite to the cigarette replenishing station 3. When it is detected that there is no cigarette pack at the cigarette replenishing station 3, the cylinder 5 at the cigarette replenishing device is activated to replenish cigarette packs.

[0026] A proximity switch 10 is arranged above the support plate 6, and the proximity switch 10 is fixedly connected to the cigarette pack storage rack 4 through a fixing plate 11. The proximity switch 10 is spaced a set distance from the upper surface of the support plate 6. Specifically, the fixing plate 11 is L-shaped, one end of which is fixed to the cigarette pack storage rack 4 by bolts, and the other end is horizontally arranged and has a threaded hole. A clevis bolt 12 is threadedly connected to the threaded hole. The proximity switch 10 is connected to the fixing plate 11 through a connecting plate. One end of the connecting plate is fixed to the proximity switch 10, and the other end is fixedly connected to the fixing plate 11 by a clevis bolt 12.

[0027] It also includes a controller, which is respectively connected to the photoelectric switch 9, the solenoid valve, the proximity switch 10 and the equipment power supply, wherein the solenoid valve is connected to the cylinder 5 through the air pipe, and is used to control the movement of the cylinder 5. The controller receives the signal of the photoelectric switch 9. When the photoelectric switch 9 does not detect that there is a cigarette pack at the cigarette replenishing station 3, the cylinder 5 is controlled by the solenoid valve to replenish the cigarette. The controller also receives the switch signal of the proximity switch 10. When the proximity switch 10 detects the support plate 6, it indicates that a cigarette squeezing failure occurs, and the support plate 6 is lifted. The controller controls the power supply of the equipment to cut off the power, so that the equipment is shut down to avoid accidents.

[0028] Since the support plate 6 is rotatably connected to the cigarette pack storage rack 4, when the cigarette replenishing station 3 is blocked, the photoelectric switch 9 does not detect the cigarette packs on the cigarette replenishing station 3. At this time, the cylinder 5 pushes the cigarette packs in the cigarette pack storage rack 4 into the cigarette replenishing station 3. The replenished cigarette packs and the cigarette packs on the cigarette replenishing station 3 are squeezed against each other, causing the cigarette packs to deform. The deformed cigarette packs can push the support plate 6 upwards, and the support plate 6 is lifted up, touching the proximity switch, realizing automatic parking of the turntable, preventing the turret from continuing to rotate and squeezing the box mold, and at the same time avoiding the problem of the equipment being stuck and shutting down due to clutch failure due to untimely fault detection.

[0029] When cleaning squeezed cigarettes, loosen the horn bolt 12, turn the proximity switch 10, and then directly open the support plate 6 to take out the squeezed cigarette packs, which is convenient for operation, significantly reduces the time for processing the turret box mold squeezed cigarettes, and improves the equipment operation efficiency.

[0030] The present invention can lift up the support plate 6 to expose the cigarette replenishing station 3 by rotatably connecting the support plate 6 and the cigarette pack storage rack 4. By arranging a proximity switch 10 on the support plate 6, when cigarette squeezing occurs, the support plate 6 can be automatically lifted to touch the proximity switch 10 to shut down the equipment, thereby preventing the turret from continuing to rotate and squeezing the box mold. At the same time, the problem of the equipment being stuck and shutting down due to clutch failure due to untimely fault discovery can be avoided. When cleaning the squeezed cigarette, the clevis bolt 12 can be loosened, the proximity switch 10 can be rotated, and the support plate 6 can be directly opened to take out the squeezed cigarette pack, thereby achieving quick cleaning and reducing the operator's work intensity.

[0031] Embodiment 2 This embodiment discloses a method for cleaning cigarette pack conveying turret smoke squeezed, using a cigarette pack conveying turret smoke squeezed device as described in the first embodiment, comprising the following steps: When the photoelectric switch detects that there are no cigarette packs in the cigarette replenishment station, the cylinder pushes the cigarette packs in the cigarette pack storage rack into the cigarette replenishment station to replenish the cigarette packs. When a cigarette squeezing failure occurs at the cigarette replenishment station, since the photoelectric switch does not detect the cigarette packs on the cigarette replenishment station, the cylinder pushes the cigarette packs in the cigarette pack storage rack into the cigarette replenishment station. The replenished cigarette packs and the cigarette packs on the cigarette replenishment station squeeze each other, causing the cigarette packs to deform. The deformed cigarette packs can push the support plate upwards, and the support plate is lifted up to touch the proximity switch, and the conveying turret stops rotating to prevent the box mold from being squeezed and damaged. At the same time, it avoids the problem that the equipment will be stuck and the clutch will stop if the fault is not discovered in time; When cleaning squeezed cigarettes, loosen the horn bolt, turn the proximity switch so that the proximity switch moves away from the top of the support plate, lift the support plate to take out the squeezed cigarette packs, replenish the cigarette packs at the replenishing station, reset the support plate and the proximity switch, and complete the cleaning of the squeezed cigarette packs.

[0032] The present invention can realize automatic shutdown due to extrusion fault, prevent the box mold from being damaged by extrusion, and avoid the problem that the equipment will be stuck and shut down due to clutch failure due to untimely fault discovery; at the same time, it can quickly clean the extruded cigarette packs at the cigarette replenishing station, so that the original 20-minute processing process is reduced to 2 minutes, which greatly reduces the labor intensity of the operating workers, improves the maintenance efficiency, reduces the equipment downtime, and reduces the maintenance cost.
