The application provides an automatic tobacco bale stacking device, which comprises a tobacco bale conveying belt 1, a lifting platform 2, a lifting pressing plate 3 and a material baffle plate 4; tobacco bale transportation area 1 is the exit side that the exit side was all located tobacco bale transportation area 1 along the both ends of its direction of transportation respectively for entrance side and exit side, elevating platform 2, lift pressure plate 3 and striker plate 4 three.

The lifting platform 2 has a lifting function and can be lifted and lowered in parallel between a high position and a low position, so that the lifting platform 2 has at least two positions of the high position and the low position along with the movement of the lifting platform 2. The lifting platform 2 at the high position is connected with the conveying surface of the cigarette packet conveying belt 1 on the same plane, and the cigarette packet 01 moved out from the outlet side of the cigarette packet conveying belt 1 can continuously move along the lifting platform 2 at the high position; the difference in height of this two of high-order and low level is not less than the height of single tobacco bale 01, and the elevating platform 2 that is in the low level is than the height of single tobacco bale 01 of the transportation tape face of tobacco bale transportation area 1 low at least, and on the basis that one deck tobacco bale 01 had been put things in good order to elevating platform 2, the tobacco bale 01 that moves out from the outlet side of tobacco bale transportation area 1 can continue to put things in good order second layer tobacco bale 01 to elevating platform 2 that is in the low level.

The striker plate 4 is positioned on one side of the lifting platform 2, which is far away from the cigarette packet conveying belt 1, in other words, the striker plate 4 and the outlet side of the cigarette packet conveying belt 1 are respectively positioned on two opposite sides of the lifting platform 2; in addition, the striker plate 4 is arranged in front of the outlet side at a preset interval along the conveying direction of the cigarette packet conveying belt 1. For example, the preset distance refers to the parallel stacking length of 5 cigarette packets 01 on the cigarette packet conveyor belt 1, and the striker plate 4 arranged in front of the outlet side can prevent the cigarette packets 01 from continuously moving when the 5 cigarette packets 01 move to the lifting platform 2, including preventing the cigarette packets 01 on the cigarette packet conveyor belt 1 from continuously moving along the conveying direction and preventing the cigarette packets 01 on the lifting platform 2 from continuously moving along the conveying direction. It can be seen that the material baffle 4 can judge and control the number of the cigarette packets 01 positioned on the lifting platform 2, and count and position the cigarette packets 01 positioned on the lifting platform 2.

The lifting and lowering platen 3 is located above the lifting and lowering table 2, and the lifting and lowering platen 3 has a lifting and lowering function as well, and for example, the lifting and lowering platen 3 has a bead 31 that moves up and down with respect to the conveying surface of the cigarette pack conveying belt 1. When the pressing strip 31 of the lifting pressing plate 3 moves relative to the lifting platform 2, the pressing strip 31 can approach the lifting platform 2 to extrude the cigarette packet 01 of the lifting platform 2, and the pressing strip 31 can also move away from the lifting platform 2 to separate from the lifting platform 2 and the cigarette packet 01 thereon.

In this automatic stacking device of tobacco bale, tobacco bale transport zone 1, elevating platform 2, lift pressure plate 3 and locate the first tobacco bale detector of striker plate 4 and all connect in same controller. The high position is the initial position of the lifting platform 2, and the initial position of the lifting pressing plate 3 is higher than the high position by at least one cigarette packet 01, so that when the cigarette packets 01 move along with the cigarette packet conveyor belt 1, the cigarette packets 01 positioned on the outlet side of the cigarette packet conveyor belt 1 enter the lifting platform 2 one by one. Because the cigarette packets 01 are stacked on the cigarette packet conveyor belt 1, even if the individual cigarette packet 01 is separated from the cigarette packet conveyor belt 1 and is positioned on the lifting platform 2, other cigarette packets 01 positioned on the cigarette packet conveyor belt 1 still push the individual cigarette packet 01 positioned on the lifting platform 2 to move continuously until the cigarette packet 01 positioned at the forefront end contacts the material baffle plate 4.

When the tobacco bale 01 contacts the material baffle plate 4, according to the counting and positioning effect of the material baffle plate 4 on the tobacco bale 01, the tobacco bale 01 with a specific number is stacked on the lifting platform 2 which is at a high position, at the moment, under the driving control of the controller, the outlet side of the tobacco bale conveying belt 1, the lifting platform 2 and the lifting pressure plate 3 are linked, and specifically, the outlet side of the tobacco bale conveying belt 1 stops outputting the tobacco bale 01, the lifting platform 2 descends, and the lifting pressure plate 3 downwards presses all the tobacco bales 01 which are at the lifting platform 2. When the lifting platform 2 is lowered from the high position to the low position, the height of the lifting platform 2 and the cigarette packet 01 thereon is lower than the conveying belt surface of the cigarette packet conveying belt 1, so that the cigarette packet 01 output by the cigarette packet conveying belt 1 can be stacked above the cigarette packet 01 of the lifting platform 2, for example, if the lifting platform 2 at the low position already stacks the first layer of cigarette packet 01, the cigarette packet conveying belt 1 can stack the second layer of cigarette packet 01 on the lifting platform 2.

With the conventional packing mode in the current cigarette market, a cigarette has two layers, and each layer has 5 cigarette packets 01, so that the automatic cigarette packet stacking device provided by the application can automatically stack a plurality of cigarette packets 01 in a 2 x 5 mode, and is convenient for subsequent packing.

When the automatic tobacco bale stacking device is used for automatically stacking tobacco bales 01, the material baffle plate 4 can play a role in counting and positioning, and the stacking number and the stacking position of the tobacco bales 01 on the lifting platform 2 are accurately controlled; the lifting pressure reducing plate 3 is matched with the action of the lifting platform 2, and can downwards extrude the cigarette packets 01 on the lifting platform 2 to adjust the relative position relation of a plurality of cigarette packets 01 on the lifting platform 2, so that the single cigarette packet 01 is prevented from inclining, and the individual cigarette packets 01, such as the cigarette packets 01 close to the cigarette packet conveying belt 1, are prevented from upwards arching, thereby realizing the purpose of providing a safe and reliable working environment for the continuous stacking of the second layer, the third layer and the fourth layer of cigarette packets 01. Further, when the elevator table 2 moves from the high position to the low position, the cigarette pack 01 on the elevator table 2 is pressed by the lifting and lowering platen 3, and the relative position between the cigarette pack 01 and the elevator table 2 can be stabilized.

To sum up, this automatic device that piles up of tobacco bale adopts tobacco bale transport zone 1, elevating platform 2, lift clamp plate 3 and striker plate 4 transportation tobacco bale 01 and piles up tobacco bale 01, has realized piling up tobacco bale 01 automatically accurately, fast reliably with simple structure, coherent action, and of course, this automatic device that piles up of tobacco bale is also applicable to the product that nevertheless easily becomes flexible similar to this kind of shape rule of tobacco bale 01.

The following provides a further description of the automatic cigarette packet stacking device provided by the present application with reference to the accompanying drawings and embodiments.

In the automatic cigarette packet stacking device, the first cigarette packet detector arranged on the material baffle plate 4 usually adopts a pressure sensor or a position sensor.

When the first cigarette packet detector is a pressure sensor, the pressure sensor is usually disposed on the surface of the striker plate 4. If tobacco bale 01 contacts striker plate 4, then pressure sensor receives the ambient pressure signal, and pressure sensor does not receive the ambient pressure signal otherwise, can judge according to pressure sensor's aforementioned two kinds of different signal states whether tobacco bale 01 contacts striker plate 4, and then judges whether elevating platform 2 has piled up the tobacco bale 01 of specific quantity.

When first tobacco bale detector was position sensor, position sensor both can be fixed in striker plate 4, also can separate in striker plate 4. If the tobacco bale 01 contacts the striker plate 4, the tobacco bale 01 shields the position sensor, otherwise, the position sensor is not shielded, whether the tobacco bale 01 contacts the striker plate 4 can be judged according to the two different signal states of the position sensor, and whether the lifting platform 2 is stacked with the tobacco bales 01 with specific quantity is further judged.

Further, this automatic stacking device of tobacco bale still includes the second tobacco bale detector of locating elevating platform 2 one side, and second tobacco bale detector is close to high level and be higher than high level. When the lifting platform 2 is in a low position and a layer of cigarette packet 01 is placed on the lifting platform 2, the second cigarette packet detector acquires a first detection signal, and the first detection signal corresponds to the situation that the lifting platform 2 only has one layer of cigarette packet 01; when the lifting platform 2 is in a low position and more than one layer of cigarette packets 01 are placed on the lifting platform 2, the second cigarette packet detector acquires a second detection signal, and the second detection signal corresponds to the situation that more than two sides of the cigarette packets 01 are arranged on the lifting platform 2. In this example, the second cigarette packet detector may also detect cigarette packet 01 when the lifting table 2 is in the high position.

In consideration of the conventional packing manner in the current cigarette market, the second detection signal of the second cigarette packet detector corresponds to the situation that two cigarette packets 01 are just on the lifting platform 2.

In addition, the automatic tobacco bale stacking device is also provided with a material blocking mechanism; the material blocking mechanism is arranged on the outlet side of the cigarette packet conveying belt 1 and is connected with the controller, and when the cigarette packet 01 contacts the material baffle plate 4, the material blocking mechanism is used for preventing the outlet side of the cigarette packet conveying belt 1 from continuously outputting the cigarette packet 01 outwards.

When tobacco bale 01 contacts striker plate 4, elevating platform 2 moves to the low level from the high position, meanwhile, tobacco bale 01 in elevating platform 2 is put to lift clamp plate 3 extrusion sign indicating number downwards, the tobacco bale 01 centre gripping that leads to elevating platform 2 is between the lower surface of lift clamp plate 3 and the upper surface of elevating platform 2, can't continue to stack tobacco bale 01 to elevating platform 2 this moment, in other words, only when elevating platform 2 descends to target in place, lift clamp plate 3 flattens the top surface of a plurality of tobacco bales 01 and lift clamp plate 3 resets the back, tobacco bale transport area 1 can only stack tobacco bale 01 to elevating platform 2. Therefore, the purpose of adopting the material blocking mechanism to prevent the cigarette packet 01 from being continuously output from the outlet side is to prevent the cigarette packet 01 of the cigarette packet conveyor belt 1 from moving out from the outlet side in the period from the time when the lifting platform 2 begins to descend to the time when the lifting platform 2 descends to the place.

Of course, besides the arrangement of the material stopping mechanism for controlling the motion state of the cigarette packet 01 at the outlet side, the intermittent motion of the cigarette packet conveyor belt 1 can be used for controlling the motion state of the cigarette packet 01 at the outlet side, so that the cigarette packet conveyor belt 1 can continuously run for the automatic cigarette packet stacking device provided with the material stopping mechanism, and can also stop running when the material stopping mechanism is started.

Two specific implementation modes are provided below for the material blocking mechanism.

In a first specific implementation manner of the blocking mechanism, the blocking mechanism is specifically a cigarette packet clamper 6 for clamping a cigarette packet 01 located on the outlet side.

The cigarette packet clamping device 6 can comprise a machine body which is relatively fixed with the cigarette packet conveying belt 1 and a clamping jaw which is arranged on the machine body; the clamping jaw is arranged above the belt surface of the cigarette packet conveying belt 1 and corresponds to the stacking height of the cigarette packets 01 on the cigarette packet conveying belt 1, and the moving direction of the clamping jaw is parallel to the belt surface of the cigarette packet conveying belt 1 and is vertical to the conveying direction of the cigarette packet conveying belt 1.

In general, the gripping jaws of the cigarette packet gripping device 6 may be used only for gripping the first cigarette packet 01 located on the exit side, and when the first cigarette packet 01 on the exit side cannot be removed from the exit side, the remaining cigarette packets 01 located on the cigarette packet conveyor belt 1 and next to the first cigarette packet 01 cannot be removed from the exit side. Obviously, in order to prevent the outlet side from discharging outwards more reliably, the jaws of cigarette packet gripper 6 may also be used to simultaneously grip a plurality of cigarette packets 01 located near the outlet side.

In a second specific implementation manner of the blocking mechanism, the blocking mechanism is specifically a cigarette packet baffle plate extending upwards from the lower side of the conveying surface.

The cigarette packet baffle plate moves up and down relative to the conveying surface, and when the cigarette packet 01 is output outwards from the outlet side of the cigarette packet conveying belt 1, the cigarette packet baffle plate is converged below the conveying surface, so that the movement of the cigarette packet 01 on the outlet side is not influenced; when the outlet side of the cigarette packet conveying belt 1 needs to stop conveying materials, the cigarette packet baffle moves upwards, the cigarette packet baffle is attached to the side wall of the tail end of the cigarette packet conveying belt 1 to shield the outlet side, and the operation of the cigarette packet conveying belt 1 is not influenced while the cigarette packets 01 are prevented from moving from the outlet side.

The cigarette packet baffle plate can move along the width direction of the conveying surface besides moving up and down relative to the conveying surface. The cigarette packet baffle can more quickly and reliably block the cigarette packet 01 when moving upwards from the lower part of the conveying surface.

In particular, in the various embodiments provided by the present application, the top surface of the lifting table 2 may be provided with a slope 21, and the slope 21 is close to the outlet side and inclines downwards towards the outlet side, which is favorable for guiding the cigarette packet 01 to move into the lifting table 2 from the outlet side.

In order to better adapt to the stacking requirement of the cigarette packet 01, the automatic cigarette packet stacking device further comprises a cylinder 5; the striker plate 4 is arranged on a push rod of the air cylinder 5, and the push rod of the air cylinder 5 is parallel to the transportation direction.

The cylinder 5 drives the striker plate 4 to be close to and keep away from the outlet side, that is to say, the cylinder 5 can adjust the distance of striker plate 4 and outlet side, including the above-mentioned predetermined interval. For example, in the automatic cigarette packet stacking device, the moving path of the striker plate 4 can comprise a near point and a far point; the distance between the striker plate 4 at the near point and the outlet side is equal to the preset distance, and the distance between the striker plate 4 at the far point and the outlet side is greater than the preset distance.

When the push rod of the air cylinder 5 is fixedly connected with the striker plate 4, the air cylinder 5 can be electrically connected with the controller. When the automatic tobacco bale stacking device is started, when the lifting platform 2 moves downwards, the controller drives the material baffle plate 4 to move from a near position point to a far position point through the air cylinder 5, and at the moment, the tobacco bale 01 of the lifting platform 2 only receives acting force of the lifting platform 2 and the lifting pressure plate 3 and cannot rub against the material baffle plate 4; when elevating platform 2 was in the low level, the controller passed through 5 drive striker plates 4 of cylinder and moved to nearly position by far position point, made striker plate 4 still be located the place ahead of outlet side with predetermineeing the interval for count and location second floor tobacco bale 01.

In addition, in the above cigarette packet automatic stacking device, one side of the lifting platform 2 is further provided with a material pushing rod for pushing out a plurality of stacked cigarette packets 01, the stretching direction of the material pushing rod is parallel to the conveying surface of the cigarette packet conveying belt 1, and the stretching direction of the material pushing rod is also perpendicular to the conveying direction of the cigarette packet conveying belt 1. When the material pushing rod is operated, a plurality of cigarette packets 01 stacked on the lifting platform 2 can be automatically pushed out of the lifting platform 2, which is commonly referred to as cigarette packaging bags pushed in by the lifting platform 2.

The above has described in detail the automatic tobacco bale stacking device that this application provided. The principles and embodiments of the present application are described herein using specific examples, which are only used to help understand the method and its core idea of the present application.
