Description

TECHNICAL FIELD

[0001] The utility model relates to cigarette packaging equipment technical field, concretely relates to a cigarette packet brake device suitable for the second drying drum entrance of FOCKE packaging machine. BACKGROUND

[0002] In the operation process of FOCKE-FX packaging machine, after the cigarette packet is dried in the first drying drum, is pushed to the conveying belt, after detecting through final cigarette packet detection device (FPI), the conveying belt is transmitted to the entrance of the second drying drum, and the second drying drum is used for the last drying treatment to the glue on the cigarette packet.

[0003] At the entrance of the second drying drum, the conveying belt continuously forwards the cigarette packet, when one drying bin of the second drying drum is filled with six cigarette packets, the tail end of the conveying belt at the entrance of the second drying drum is braked by the brake mechanism to the subsequent cigarette packet, so as not to cause the subsequent cigarette packet to cause congestion, and block the rotation of the second drying drum, at the same time, the second drying drum rotates to the next drying bin to prepare for filling, when filling, the brake is released, and the conveying belt continues to convey the cigarette packet forwards, and so on.

[0004] However, in the production process, the existing air bag type brake system has poor use effect, and frequently causes the blockage of the entrance of the second drying drum. Figure 13 The original machine brake is composed of nine groups of air bags (see When the air bag holds and brakes the cigarette packet, the contact area of the air bag and the cigarette packet is approximately point contact, the contact area is small, so that the brake friction force cannot be provided for the cigarette packet. If the air bag type brake system is adjusted too close to the cigarette packet, the conveying belt conveying the cigarette packet will not be smooth, so that the cigarette packet cannot be filled neatly in the second drying drum, and even the situation of skew or not conveying in place can occur, further affecting the rotation of the second drying drum, and producing defective cigarette packets.

[0005] In addition, since the FOCKE-FX packaging machine needs to frequently replace the trademark materials of different brands and different auxiliary material suppliers, the surface friction of these trademark materials is different, so that the friction required for the brake to brake the cigarette packet also changes accordingly. This makes it difficult for the existing air bag type brake system to be adjusted to an ideal state, and cannot meet the production requirements. If the brake system cannot effectively brake the cigarette packet, the conveying belt will continuously convey the cigarette packet forward, causing the cigarette packet to be congested, affecting the rotation of the second drying drum, and further producing defective cigarette packets.

[0048] The first sensor reflector plate (45) is fixedly connected to the guide mechanism second connecting plate (44).

[0049] The working principle of the utility model mainly comprises:

[0050] 1. Sensor monitoring:

[0051] The first sensor (7) judges the accumulation condition of the cigarette packet (A) at the guide mechanism (4) by detecting whether the first sensor reflector plate (45) is blocked by the cigarette packet (A). When the first sensor reflector plate (45) is blocked by the cigarette packet (A), the first sensor (7) is lighted, and vice versa. When the first sensor (7) flashes once (lighting-out-lighting), that is, the conveying belt (B) supplements two cigarette packets.

[0052] The second sensor (8) judges the accumulation condition of the cigarette packet (A) at the brake mechanism (1) and the positioning mechanism (3) by detecting whether the second sensor reflector plate (35) is blocked by the cigarette packet (A). When the second sensor reflector plate (35) is blocked by the cigarette packet (A), the second sensor (8) is lighted, and vice versa.

[0053] Third sensor (9): Determine whether a drying chamber of the second drying drum (C) is full of six packs of cigarettes (A) by whether the contact (D1) on the baffle (D) is triggered. When the contact (D1) on the baffle (D) is triggered by the cigarette pack (A), the third sensor (9) connected with the contact (D1) is on, otherwise it is off.

[0054] 2. Brake mechanism triggering:

[0055] When the third sensor (9) is on (i.e. a drying chamber of the second drying drum is full of six packs of cigarettes), the second sensor (8) is on (i.e. the brake mechanism and the positioning mechanism are full of cigarette packs), and the first sensor (7) flashes N times (N can be set by the control system program) (i.e. 2N packs of cigarettes are added in front), it means that a drying chamber of the second drying drum (C) is full of six packs of cigarettes (A), and there are enough cigarette packs (A) in front of the entrance for packing.

[0056] At this time, the control system controls the electromagnetic valve to drive the diaphragm type clamping cylinder (11) of the brake mechanism (1) to act. The diaphragm of the diaphragm type clamping cylinder drives the brake plate (17) and the friction buffer plate (18) to stretch out against the spring (132) force, together with the positioning mechanism (3), to clamp and brake the cigarette packs (A) at the entrance of the second drying drum (C), at this time the spring (132) is compressed.

[0057] 3. Drying chamber switching and brake release:

[0058] At the same time when the brake mechanism (1) clamps and brakes the cigarette packs (A), the control system controls the second drying drum (C) to rotate once to switch to the next drying chamber. At this time, the contact (D1) returns to the untriggered state, and the third sensor (9) is off.

[0059] When the third sensor (9) is off, the second drying drum (C) stops rotating, and the control system controls the electromagnetic valve to drive the diaphragm type clamping cylinder (11) of the brake mechanism (1) to act again, and the diaphragm returns to its original position. The brake plate (17) and the friction buffer plate (18) quickly rebound under the action of the spring (132) force, and the brake mechanism (1) releases the cigarette packs.

[0060] 4. Conveyor belt packing and circulation:

[0061] After the brake mechanism (1) is released, the conveyor belt (B) continues to move the cigarette packs (A) forward for packing.

[0062] Until the three sensors again monitor that the brake mechanism triggering condition is met, the entire brake process is started again, and the cycle is repeated.

[0063] 5. Control of the rotation speed of the second drying drum:

[0064] When the device is running normally but the first sensor (7) is lit for more than a preset time, it indicates that the second drying drum (C) rotates too slowly, causing a large amount of cigarette packets to accumulate at the inlet thereof, at which time the control system controls the rotation speed of the second drying drum (C) to be increased.

[0065] 6. Brake plate design:

[0066] The brake plate (17) is designed as a flat plate, and is provided with a friction buffer plate (18) in surface contact with the cigarette packet (A), so that the contact area of the brake mechanism (1) and the cigarette packet (A) is increased, and greater braking friction can be provided.

[0067] The friction buffer plate (18) can provide braking friction to the cigarette packet (A) and buffer the brake plate (17).

[0068] 7. Brake support design:

[0069] In order to meet the needs of position adjustment of the brake mechanism (1) in all directions, the waist-shaped hole design is adopted at multiple positions of the brake support (2), so that the position of the brake mechanism in six dimensions, such as height, left and right, front and back, can be adjusted.

[0070] The beneficial effects of the utility model are as follows:

[0071] 1. The utility model improves the reliability of cigarette packet braking: the utility model adopts a mechanical brake mechanism combining a diaphragm type clamping air cylinder and a brake plate and a friction buffer plate, increases the contact area with the cigarette packet, effectively improves the braking friction, and ensures reliable braking of the cigarette packet. The brake mechanism and the positioning mechanism work cooperatively to form stable clamping force, avoiding the problem of insufficient braking friction caused by the air bag type brake system.

[0072] 2. The utility model reduces the blocking and shutdown times of the equipment and eliminates the generation of defective cigarette packets: sufficient braking friction provided by the brake mechanism, combined with accurate sensor monitoring and control system logic, realizes accurate brake braking of the cigarette packet, effectively prevents the blocking of the cigarette packet at the inlet of the second drying drum. Reducing the shutdown times caused by blocking improves the operation efficiency of the packaging machine and the overall stability of the production line. At the same time, the generation of defective cigarette packets caused by cigarette packet extrusion is eliminated.

[0073] 3. The utility model improves the adaptability of the equipment: the utility model can provide sufficient braking friction to cigarette packets packaged by different brands and different auxiliary material suppliers, improving the adaptability of the packaging equipment.

[0132] In summary, the specific usage process of this utility model is as follows:

[0133] First, such as Figure 4 As shown, the components of this utility model are installed at the inlet of the second drying drum C and their positions are adjusted. The positions of the braking mechanism 1 in six dimensions, including height, left and right, front and back, are adjusted. Then, a trial run is conducted until the operation is smooth and the braking mechanism 1 can effectively brake the tobacco pack A, and the three sensors can accurately trigger and transmit signals to the control system.

[0134] Furthermore, such as Figure 1 — Figure 3 As shown, when the operating equipment simultaneously meets the conditions of the third sensor 9 lighting up (i.e., one drying chamber of the second drying drum is filled with six packs of cigarettes), the second sensor 8 lighting up (i.e., the brake mechanism and positioning mechanism are filled with cigarette packs), and the first sensor 7 flashing twice (i.e., adding four more packs of cigarettes), it indicates that one drying chamber of the second drying drum C is filled with six packs of cigarettes A, and there are enough packs of cigarettes A piled up in front of the inlet for filling and replenishing.

[0135] At this time, the control system controls the solenoid valve to drive the diaphragm clamping cylinder 11 of the braking mechanism 1 to operate. The diaphragm of the diaphragm clamping cylinder drives the brake plate 17 and the friction buffer plate 18 to extend against the elastic force of the spring 132, and together with the positioning mechanism 3, clamps and brakes the tobacco pack A at the inlet of the second drying drum C. At this time, the spring 132 is compressed.

[0136] While the braking mechanism 1 clamps the brake pack A, the control system controls the second drying drum C to rotate once, switching to the next drying chamber. At this time, contact D1 returns to the untriggered state, and the third sensor 9 is turned off.

[0137] Furthermore, such as Figure 1 — Figure 3 As shown, when the third sensor 9 is turned off, the second drying drum C stops rotating. The control system controls the solenoid valve to drive the diaphragm clamping cylinder 11 of the brake mechanism 1 to act again. The diaphragm returns to its original position, and the brake plate 17 and the friction buffer plate 18 quickly rebound under the elastic force of the spring 132. The brake mechanism 1 releases the cigarette pack.

[0138] After the brake mechanism 1 is released, the conveyor belt B continues to drive the cigarette pack A forward to replenish the pack.

[0139] The braking process restarts once the three sensors detect that the braking mechanism trigger conditions are met again, and this cycle repeats continuously.

[0140] When the device is in normal operation but the first sensor 7 is lighted up for more than a preset time, it indicates that the second drying drum C rotates too slowly, resulting in more tobacco packets accumulated at the inlet thereof, at this time, the control system controls the rotation speed of the second drying drum C to be accelerated.

[0141] With the passage of time, all the tobacco packets A are filled into the second drying drum C for drying treatment, and then are conveyed to the next process.

[0142] Finally, it should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included in the protection scope of the present application.
