[0002] When the FOCKE packaging machine is working, it first combines cigarette packs input by an upstream machine into cigarette pack groups. Each cigarette pack group includes two cigarette packs, one on top of the other. Then, the cigarette pack groups are conveyed to a downstream machine through a conveyor belt to complete the packaging of cartons and carton transparent paper. However, the existing cigarette replenishing tower cannot store a large number of cigarette packs, and operators need to continuously add them manually, resulting in too low replenishing efficiency. At the same time, since the conveyor belt includes two parallel conveyor belts arranged vertically and horizontally, when the cigarette pack group is pushed between the two conveyor belts, it is easy to collide with the upper conveyor belt, causing damage to the cigarette packs and affecting the final packaging quality.

[0075] In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0076] Figure 5 The figure shows the front view of the turret mechanism. In the following description, the accompanying drawings in Figure 5 are used as the reference basis for directions. In Figure 5 , the direction perpendicular to the drawing paper and facing outward is the front direction, the direction perpendicular to the drawing paper and facing inward is the rear direction, the direction upward along the drawing paper is the upper direction, the direction downward along the drawing paper is the lower direction, the direction to the right along the drawing paper is the right direction, and the direction to the left along the drawing paper is the left direction. Among them, the rotating shaft 19 extends in the up and down direction, and the cigarette pushing channel 33 extends in the front and rear directions.

[0077] As Figure 1 shown, the present invention provides a cigarette pack replenishing device, including a turret mechanism 1, a cigarette pushing mechanism 3, and a control mechanism. Among them, as Figures 1-6 shown, the turret mechanism 1 includes a rotating shaft 19 that rotates under the drive of a rotation driving member 5, a plurality of bins 16 circumferentially distributed along the rotating shaft 19, and a bottom plate 18 provided at the bottom of the rotating shaft 19. A blanking port 181 extending along the radial direction of the bottom plate 18 is provided on the bottom plate 18. As Figures 8-10As shown in the figure, the cigarette pushing mechanism 3 includes a cigarette packet mouth 34 that makes a linear displacement under the drive of a cigarette packet mouth driving member 34a, a cigarette pushing channel 33 provided at the bottom of the cigarette packet mouth 34, a collision prevention piece 31 rotatably connected to the top of the cigarette packet mouth 34, a cigarette packet push rod 35, and two cigarette packet stop rods 32. The cigarette pushing channel 33 is located below the material dropping port 181. The cigarette packet push rod 35 makes a linear displacement along the cigarette pushing channel 33 under the drive of a cigarette packet push rod driving member 35a to control the opening and closing of the material dropping port 181. The two cigarette packet stop rods 32 are respectively arranged on both sides of the cigarette pushing channel 33 and make a linear displacement under the drive of a cigarette packet stop rod driving member. Specifically, the cigarette packet stop rod 32 on the left side of the cigarette pushing channel 33 is the first cigarette packet stop rod 321, which makes a linear displacement under the drive of a first cigarette packet stop rod driving member 321a; the cigarette packet stop rod 32 on the right side of the cigarette pushing channel 33 is the second cigarette packet stop rod 322, which makes a linear displacement under the drive of a second cigarette packet stop rod driving member 322a.

[0078] Combined with Figure 8 and Figure 10 it can be seen that the working principle of the present invention is as follows:

[0079] In the initial state, the cigarette packet pusher 35 is located below the blanking port 181, the blanking port 181 is closed, and the cigarette packets 7 in the bin 16 at the unloading station are stacked on the cigarette packet pusher 35. During operation, the cigarette packet pusher driving member 35a drives the cigarette packet pusher 35 to move backward, the blanking port 181 opens, and two cigarette packets 7 in the bin 16 fall through the blanking port 181 into the cigarette pushing channel 33. At this time, the cigarette packet mouth covering driving member 34a drives the cigarette packet mouth covering 34 to move forward, and the first cigarette packet blocking rod driving member 321a and the second cigarette packet blocking rod driving member 322a respectively drive the first cigarette packet blocking rod 321 and the second cigarette packet blocking rod 322 to extend between the upper conveyor belt 81 and the lower conveyor belt 82. Then the cigarette packet pusher driving member 35a drives the cigarette packet pusher 35 to move forward. While closing the blanking port 181, it pushes the two stacked cigarette packets 7 through the cigarette packet mouth covering 34 into the space between the upper conveyor belt 81 and the lower conveyor belt 82, and between the first cigarette packet blocking rod 321 and the second cigarette packet blocking rod 322. During the process of the two cigarette packets 7 passing through the cigarette packet mouth covering 34, the anti-collision piece 31 is pushed by the cigarette packet 7 to flip upward and is located between the cigarette packet 7 and the upper conveyor belt 81, playing a role in preventing the cigarette packet 7 from colliding with the upper conveyor belt 81. Subsequently, the cigarette packet mouth covering driving member 34a drives the cigarette packet mouth covering 34 to move backward, driving the anti-collision piece 31 to leave between the cigarette packet 7 and the upper conveyor belt 81. Then the first cigarette packet blocking rod driving member 321a and the second cigarette packet blocking rod driving member 322a respectively drive the first cigarette packet blocking rod 321 and the second cigarette packet blocking rod 322 to move backward, and the cigarette packet pusher driving member 35a drives the cigarette packet pusher 35 to move backward. The two cigarette packets 7 can be smoothly conveyed to the downstream machine along with the upper conveyor belt 81 and the lower conveyor belt 82. If all the cigarette packets 7 in the current bin 16 have been conveyed, the rotation driving member 5 drives the rotating shaft 19 to rotate, so that the next bin 16 rotates to the unloading station to unload the cigarette packets therein.

[0080] As Figures 1-3 shown, in a specific embodiment of the present invention, the turret mechanism 1 further includes a plurality of fixing plates 11 spaced apart on the rotating shaft 19. The fixing plates 11 are specifically polygonal, and a back plate 12 extending along the axial direction of the rotating shaft 19 is correspondingly provided at each side. The plurality of fixing plates 11 can fix the back plate 12 in the extending direction of the back plate 12. The number of back plates 12 is equal to the number of sides of each fixing plate 11, realizing the fixation of the plurality of fixing plates 11 to the plurality of back plates 12. A side plate 16 is provided on each side of each back plate 12, and a baffle 14 is further provided on one of the side plates 16. Thus, a back plate 12 and two side plates 16 enclose a bin 16 with open upper and lower ends and four-way limit in the front, rear, left, and right directions. Such a setting can make the two cigarette packets falling into the cigarette pushing channel 33 form a stacked cigarette packet group. Adjacent two bins 16 are connected by a connecting member 15, so that the plurality of bins 16 are connected as a whole and rotate synchronously with the rotating shaft 19.

[0081] The rotary drive member 5 is arranged at the upper end of the rotary shaft 19 and is connected to the rotary shaft 19 through a speed reducer. The specific form of the rotary drive member 5 in the present invention is not limited, and it can be a servo motor or a stepping motor, etc. The operator can obtain the mass and moment of inertia of the entire turret mechanism 1 through program simulation and calculation, and based on the time required for the turret mechanism 1 to rotate one station as expected, obtain the torque of the cooperation between the rotary drive member 5 and the speed reducer, so as to determine the models of the rotary drive member 5 and the speed reducer.

[0082] As Figure 7 shown, a plurality of metal sheets 64 are also arranged at intervals on the uppermost fixing plate 11. The number of the metal sheets 64 is the same as that of the bins 16, and they correspond to each other one by one; the turret mechanism 1 further includes a position-fixed positioning sensor 63 that does not rotate with the rotary shaft 19. When the positioning sensor 63 senses any one of the metal sheets 64, the bin 16 corresponding to the metal sheet 64 is at the unloading station, that is, directly above the blanking port 181, and subsequent unloading can be carried out. Specifically, a metal sheet 64 is provided at each vertex of the fixing plate 11, and the positioning sensor 63 is a proximity switch that cooperates with the metal sheet 64 for induction.

[0083] As Figures 1-6 shown, the turret mechanism 1 further includes a protective cover 17 covering the outside of the bin 16 and a protective plate 2 located outside the protective cover 17. Both of them do not rotate synchronously with the rotary shaft 19, which can prevent personnel from touching the components in the working state. The aforementioned positioning sensor 63 is fixed on the protective cover 17. The upper end of the rotary shaft 19 is connected to the protective cover 17 through a first bearing 191. Specifically, the first bearing 191 is a double-row angular contact bearing; the lower end of the rotary shaft 19 is connected to the protective cover 17 through a second bearing 192 and a third bearing 193. Specifically, the second bearing 192 is a thrust bearing, and the third bearing 193 is a needle bearing. The first bearing 191, the second bearing 192, and the third bearing 193 ensure the smooth rotation of the rotary shaft 19 in the protective cover 17. Preferably, a protective door 171 is further provided on the protective cover 17, and the unloading station is arranged facing the protective door 171.

[0084] As Figure 2 and Figure 5As shown in the figure, a photoelectric sensor 61 and a reflector 62 are further provided on the protective cover 17, and a light passing hole 131 is provided on each of the two side plates 13 in each bin 16. Specifically, the height of the photoelectric sensor 61 is lower than that of the reflector 62, and the two light passing holes 131 are not at the same height. When the bin 16 rotates to the unloading station along with the rotating shaft 19, the photoelectric sensor 61, the two light passing holes 131 and the reflector 62 are on the same straight line. Its working principle is as follows: when the number of cigarette packs in the bin 16 is greater than or equal to two packs, the cigarette packs will block the light passing holes 131 and prevent the laser emitted by the photoelectric sensor 61 from reaching the reflector 62; when the number of cigarette packs in the bin 16 is less than two packs, the light passing holes 131 are exposed, and the laser emitted by the photoelectric sensor 61 reaches the reflector 62 and is then reflected back to the photoelectric sensor 61, and the light energy will decay. Thus, it is possible to confirm whether the number of cigarette packs in the bin 16 is sufficient for the next cigarette pushing operation according to the light energy received by the photoelectric sensor 61.

[0085] As Figure 9 shown in the figure, to ensure the smooth movement of the cigarette pack pusher 35, the present invention further includes a guide shaft 35c that is fixedly positioned and extends along the extending direction of the cigarette pushing channel 33. The cigarette pack pusher driving member 35a is connected to the cigarette pack pusher 35 through a connecting bracket 35b, and the connecting bracket 35b is slidably connected to the guide shaft 35c. When the cigarette pack pusher driving member 35a works, it drives the connecting bracket 35b to slide along the guide shaft 35c, and further drives the cigarette pack pusher 35 to move along the cigarette pushing channel 33, preventing the cigarette pack pusher 35 from shifting.

[0086] The forms of the cigarette pack mouth driving member 34a, the cigarette pack pusher driving member 35a, the first cigarette pack blocking rod driving member 321a, and the second cigarette pack blocking rod driving member 322a adopted by the present invention are not limited, and can be devices such as linear motors, cylinders or hydraulic cylinders that can output linear displacements. Preferably, when the cigarette pack pusher driving member 35a is a cylinder, a reed switch can be provided on the cigarette pack pusher driving member 35a to detect the position of the cylinder piston rod through the reed switch, helping to judge whether the cigarette pack pusher 35 has moved in place. In addition, the moving speed of the cylinder piston rod and the cigarette pack pusher 35 can be adjusted by changing the air intake and exhaust volumes of the cylinder.

[0087] As Figure 1 and Figure 9 shown in the figure, the present invention is further provided with an operation panel 4, and there are three buttons of "Automatic", "Jog" and "Stop" on the operation panel 4. A green indicator light is provided inside the "Automatic" button, and a red indicator light is provided inside the "Stop" button. The red indicator light flashes when the cigarette pack replenishing device itself has a fault, and the fault conditions include servo faults, servo over-torque faults, protective door faults, etc. When the packaging machine has a fault, the red indicator light stays on to give a reminder.

[0088] The control mechanism is connected to the rotary drive member 5, the cigarette pack mouth driving member 34a, the cigarette pack push rod driving member 35a, the first cigarette pack stop rod driving member 321a, the second cigarette pack stop rod driving member 322a, the position sensor 63, the photoelectric sensor 61, the reed switch, and the operation panel 4. Specifically, the control mechanism can be a single-chip microcomputer or a PLC controller, and the present invention does not limit this.

[0089] The present invention also provides a method for using the cigarette pack replenishing device, including the following steps:

[0090] When manually adding cigarette packs: Open the protective door 171. When adding cigarette packs to the bin 16 at the unloading station until the bin 16 is full, close the protective door 171, click the "jog" button, and the rotary drive member 5 drives the rotary shaft 19 to rotate, so that the next bin 16 is at the unloading station. At this time, the protective door 171 can be opened to add cigarette packs again. Repeat the above steps until all bins 16 are in the full state. At this time, the "automatic" button can be pressed, and the green indicator light stays on, indicating that both the packaging machine and the cigarette pack replenishing device are in the normal operating state.

[0091] When replenishing cigarette packs:

[0092] The cigarette pack push rod 35 is located below the blanking port 181, and the blanking port 181 is closed;

[0093] The second cigarette pack stop rod driving member 322a drives the second cigarette pack stop rod 322 to extend between the upper conveyor belt 81 and the lower conveyor belt 82. The cigarette pack mouth driving member 34a drives the cigarette pack mouth 34 to move forward. After the cigarette pack push rod 35 stays for a full preset time, the cigarette pack push rod driving member 35a drives the cigarette pack push rod 35 to move backward, and the blanking port 181 is opened. Two cigarette packs in the bin fall through the blanking port 181 into the cigarette pushing channel 33. Then, the first cigarette pack stop rod driving member 321a drives the first cigarette pack stop rod 321 to extend between the upper conveyor belt 81 and the lower conveyor belt 82;

[0094] The cigarette pack push rod driving member 35a drives the cigarette pack push rod 35 to move forward, pushing the two stacked cigarette packs through the cigarette pack mouth 34 into the space between the upper conveyor belt 81 and the lower conveyor belt 82. The anti-collision piece 31 is located between the cigarette pack and the upper conveyor belt 81. The two cigarette packs are located between the first cigarette pack stop rod 321 and the second cigarette pack stop rod 322 and do not move with the upper conveyor belt 81 and the lower conveyor belt 82;

[0095] The cigarette pack mouth driving member 34a drives the cigarette pack mouth 34 to move backward, driving the anti-collision piece 31 to leave between the cigarette pack and the upper conveyor belt 81. The first cigarette pack stop bar driving member 321a and the second cigarette pack stop bar driving member 322a respectively drive the first cigarette pack stop bar 321 and the second cigarette pack stop bar 322 to move backward. After the cigarette pack pusher 35 stays for the full preset time, the cigarette pack push rod driving member 35a drives the cigarette pack push rod 35 to move backward, and the two cigarette packs are smoothly conveyed to the downstream machine along with the upper conveyor belt 81 and the lower conveyor belt 82.

[0096] When the photoelectric sensor 61 detects that there are at least two cigarette packs in the bin 16 at the unloading station, the replenishment program will continue to be executed; when the photoelectric sensor 61 detects that there are less than 2 cigarette packs in the bin 16 at the unloading station, the control mechanism controls the turret mechanism 1 to rotate to unload the next bin 16. If the photoelectric sensor 61 detects that there are still less than two cigarette packs in the next bin 16, the unloading of the entire turret mechanism 1 is completed, and the cigarette pack replenishment device is on standby.

[0097] The present invention also provides a packaging machine, including the aforementioned cigarette pack replenishment device.

[0098] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
