Description

Technical Field

[0001] The present invention relates to the technical field of cigarette pack conveying, and in particular to a cigarette pack conveying mechanism with a decompression function. Background Art

[0002] The cigarette packing machine is mainly used to wrap cigarettes in folded liner paper, attach white cardboard, and then complete the cigarette packaging work of wrapping trademark paper and transparent paper. Its purpose is to make it easy to carry cigarettes while keeping them moist and fragrant, extend the shelf life of cigarettes, and further highlight the product grade and brand culture.

[0003] like Figure 7 As shown, the existing cigarette pack conveying process is as follows: the cigarette packs are conveyed by the upstream equipment, and under the clamping and conveying of the upper synchronous belt (synchronous conveyor belt 10) and the lower synchronous belt (synchronous conveyor belt 10), the 8-pack side-by-side cigarette pack group is passively conveyed to the separation drum 80, and the cigarette packs enter the mold box of the separation drum 80 in groups of 2, and the separation drum always rotates clockwise to convey the cigarette packs to the downstream equipment.

[0004] like Figure 7 , Figure 8 As shown, while the mold box of the separation drum 80 is conveying the cigarette packs to the downstream equipment, the cigarette packs in the conveying channel 30 are also waiting for the next mold box of the separation drum 80 to rotate into place. During this period, the cigarette packs in the conveying channel 30 are always squeezed forward by the forward conveying force of the synchronous conveyor belt 10. In order to prevent the cigarette packs from rushing out and causing blockage, the first clamper 40 clamps and fixes the cigarette packs at the front end (downstream end) in the conveying channel 30 during the interval of cigarette pack separation. The cigarette packs at the rear are all squeezed to the rear due to the clamping of the front cigarette packs, waiting for the next round of release.

[0005] In actual production, cigarette packs tend to be slightly skewed at the clamping point, so that when the cigarette packs enter the mold box of the separation drum, one end of the cigarette packs first touches the plane of the separation drum mold box, which eventually causes damage to the cigarette packs. The reason is that on the one hand, there are too many cigarette packs accumulated, and there is a large impact force at the moment of release; on the other hand, the cigarette packs behind always exert a squeezing force on the cigarette packs in front during the waiting period, and as the amount of cigarette packs accumulates, the squeezing force on the cigarette packs in front continues to increase, which leads to the tilt of the cigarette pack arrangement.

[0006] Therefore, how to reduce the squeezing force exerted on the downstream cigarette packs when the cigarette packs are piled up has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0007] In view of this, an object of the present invention is to provide a cigarette pack conveying mechanism with a decompression function to solve the technical problem of excessive squeezing force on downstream cigarette packs in the existing cigarette pack conveying mechanism.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0050] Examples, such as Figure 1-Figure 6 As shown, a cigarette pack conveying mechanism with a decompression function comprises:

[0051] The synchronous conveyor belt 10 is two in number, and the two synchronous conveyor belts 10 are arranged in a transverse direction, and the two synchronous conveyor belts 10 are arranged in parallel one above the other.

[0052] The conveying guide rails 20 are two in number, and the two conveying guide rails 20 are arranged between the two synchronous conveyor belts 10 along the transverse direction; the two conveying guide rails 20 are arranged at intervals along the longitudinal direction to form a conveying channel 30 between the two synchronous conveyor belts 10 and the two conveying guide rails 20.

[0053] The first clamper 40 is disposed at the downstream end of the conveying passage 30 .

[0054] The detection module 50 is disposed on the conveying guide rail 20 , and the detection module 50 is capable of detecting the cigarette pack conveying information in the conveying channel 30 .

[0055] The second clamper 60 is disposed on the conveying guide rail 20 , and the second clamper 60 is located between the first clamper 40 and the detection module 50 .

[0056] A control module, which is electrically signal connected to the detection module 50, and the control module can receive the cigarette pack conveying information in the conveying channel 30 detected by the detection module 50; the control module is control-connected to the second clamper 60, and the control module can control the second clamper 60 to apply lateral friction force to the cigarette pack 70 in the conveying channel 30 according to the cigarette pack conveying information, so as to reduce the lateral squeezing force on the cigarette pack 70 at the downstream end of the conveying channel 30.

[0057] The present application is provided with a second clamper 60 and a detection module 50 on the conveying guide rail 20 on both sides of the conveying channel 30. The detection module 50 can be used to detect the stacked number of cigarette packs 70 in the conveying channel 30, and the second clamper 60 can exert a lateral friction force on the laterally stacked cigarette packs 70 through the longitudinal clamping effect on the cigarette packs 70, thereby reducing the lateral stacking pressure of the upstream cigarette packs 70 on the downstream cigarette packs 70, so as to reduce the stacking pressure of the cigarette packs 70 in the conveying channel 30, ensure the arrangement posture of the cigarette packs 70, and reduce the impact force when the cigarette packs 70 enter the separation drum, thereby ensuring that the cigarette packs 70 will not collide when entering the separation drum mold box.

[0058] It should be noted that the horizontal direction in this embodiment refers to Figure 3 The double arrow in the figure indicates that the longitudinal direction in this embodiment refers to Figure 3 The single arrow direction in the figure, and the specific structure and installation position of the first clamp 40 are prior art, which will not be described in detail here.

[0059] In a specific embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, the two conveying guide rails 20 are arranged at a longitudinal distance, and both conveying guide rails 20 include an upstream section 21 and a downstream section 22 arranged along the transverse direction, and the distance between the upstream section 21 and the downstream section 22 is set so that the middle and downstream positions of the conveying guide rails 20 form an installation station for installing the second clamper 60. The second clamper 60 includes a static extrusion plate 61 and a dynamic extrusion plate 62. The static extrusion plate 61 is fixedly arranged between the upstream section 21 and the downstream section 22 of one of the conveying guide rails 20, and the dynamic extrusion plate 62 is arranged between the upstream section 21 and the downstream section 22 of the other conveying guide rail 20. The dynamic extrusion plate 62 is opposite to the static extrusion plate 61 and can move back and forth longitudinally, so as to adjust the longitudinal distance between the static extrusion plate 61 and the dynamic extrusion plate 62, so as to longitudinally extrude the cigarette packs 70 accumulated in the conveying channel 30 through the static extrusion plate 61 and the dynamic extrusion plate 62, and apply a dynamic friction force opposite to the movement direction to the cigarette packs 70, thereby reducing the lateral stacking pressure of the upstream cigarette packs 70 on the downstream cigarette packs 70 in the conveying channel 30.

[0060] This arrangement is because: in the prior art, the two conveying guide rails 20 are of an integral structure, which can only guide the cigarette packs 70 in the conveying channel 30, but cannot reduce the lateral stacking pressure of the upstream cigarette packs 70 on the downstream cigarette packs 70. In this embodiment, the two conveying guide rails 20 are of a split structure, so that the middle part of the two conveying guide rails 20 can form an installation station for installing the second clamper 60. When the number of cigarette packs 70 stacked in the conveying channel 30 exceeds the specified number, the lateral stacking pressure of the upstream cigarette packs 70 on the downstream cigarette packs 70 will exceed the bearing range of the downstream cigarette packs 70. At this time, the control module will control the dynamic extrusion plate 62 of the second clamper 60 to move longitudinally toward the static extrusion plate 61, thereby applying a longitudinal extrusion force to some of the stacked cigarette packs 70 in the conveying channel 30, so that friction is generated between the dynamic extrusion plate 62 and the static extrusion plate 61 and the cigarette packs 70. Since the direction of the friction force applied by the dynamic extrusion plate 62 and the static extrusion plate 61 to the cigarette packs 70 is opposite to the conveying direction of the cigarette packs 70, in the lateral direction, the stacking pressure of the upstream cigarette packs 70 on the downstream cigarette packs 70 is reduced, thereby alleviating the squeezing phenomenon of the downstream cigarette packs 70.

[0061] It should be noted that the friction force of the dynamic extrusion plate 62 and the static extrusion plate 61 on the cigarette pack 70 is proportional to the pressure of the dynamic extrusion plate 62 and the static extrusion plate 61 on the cigarette pack 70 in the conveying channel 30. It is most preferred that the friction force of the dynamic extrusion plate 62 and the static extrusion plate 61 on the cigarette pack 70 in the conveying channel 30 is dynamic friction. In this way, not only can the lateral pressure of the upstream cigarette pack 70 on the downstream cigarette pack 70 in the conveying channel 30 be reduced, but also the normal conveyance of the cigarette pack 70 in the conveying channel 30 can be ensured.

[0062] In a specific embodiment, if Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the second clamper 60 includes a static extrusion plate 61, a dynamic extrusion plate 62, a mounting frame 63, a guide frame 64 and a telescopic driving member 65; wherein, the static extrusion plate 61 is fixedly mounted on the first conveying guide rail 20, and the static extrusion surface of the static extrusion plate 61 is coplanar with the guide surface of the first conveying guide rail 20; the mounting frame 63 is arranged on the outer side of the second conveying guide rail 20, and the guide frame 64 is arranged on the second conveying guide rail 20, and the guide surface of the guide frame 64 is opposite to the static extrusion surface of the static extrusion plate 61, and at the same time, the guide surface of the guide frame 64 is coplanar with the guide surface of the second conveying guide rail 20.

[0063] The top end of the guide frame 64 is fixedly connected to one end of the longitudinal connecting plate, and the other end of the longitudinal connecting plate is fixedly connected to the mounting frame 63; the telescopic driving member 65 is fixedly connected between the mounting frame 63 and the movable extrusion plate 62, and the telescopic driving member 65 can drive the movable extrusion plate 62 to reciprocate along the longitudinal direction. The guide frame 64 is provided with an avoidance opening that cooperates with the movable extrusion plate 62, so that the movable extrusion plate 62 and the static extrusion plate 61 apply friction to the stacked cigarette packs 70.

[0064] Preferably, Figure 5 , Figure 6 As shown, a positioning connecting plate 67 is provided at the top and bottom ends of the mounting frame 63 on the side facing the movable extrusion plate 62, the positioning connecting plate 67 is arranged in the longitudinal direction, and a stop block 68 is vertically fixedly connected to the lower part of the other end of the positioning connecting plate 67; a positioning protrusion 66 is provided at the top and bottom ends of the movable extrusion plate 62, the positioning protrusion 66 is arranged in the transverse direction, and the positioning protrusion 66 is located between the stop block 68 and the mounting frame 63, so that in the process of the movable extrusion plate 62 moving longitudinally toward the static extrusion plate 61, the stop block 68 can form a stop cooperation with the positioning protrusion 66, thereby realizing the limitation of the movable extrusion plate 62 and preventing the movable extrusion plate 62 from excessively extruding the cigarette pack 70.

[0065] More preferably, Figure 5 As shown, an outer guide arc surface 641 is provided at the upstream end of the guide frame 64, that is, an outer guide arc surface 641 is provided at one end of the guide frame 64 close to the upstream section 21 of the conveying guide rail 20, so that the cigarette packs 70 located between the upstream sections 21 can smoothly enter between the guide frame 64 and the static extrusion plate 61; an inner guide arc surface 621 is provided at the upstream end of the dynamic extrusion plate 62, that is, an inner guide arc surface 621 is provided at one end of the dynamic extrusion plate 62 close to the upstream section 21 of the conveying guide rail 20, so that the cigarette packs 70 located between the upstream sections 21 can smoothly enter between the dynamic extrusion plate 62 and the static extrusion plate 61.

[0066] More preferably, the dynamic extrusion plate 62 is a rubber plate, and the static extrusion plate 61 is a stainless steel plate.

[0067] In a specific embodiment, if Figure 5 , Figure 6 As shown, the telescopic driving member 65 is an airbag, which is connected to an air source through a pipeline, and a solenoid valve is provided on the pipeline. The solenoid valve is connected to an electrical signal of a control module for controlling the inflow and outflow of compressed air inside the airbag.

[0068] This arrangement is because: the airbag uses compressed air to drive the dynamic extrusion plate 62 to move longitudinally, which not only has a flexible buffering function, but also the leaked compressed air will not have a negative impact on production.

[0069] Preferably, a pressure reducing valve is provided on the pipeline to control the pressure of the compressed air entering the airbag through the pressure reducing valve.

[0070] In a specific embodiment, if Figure 3 As shown, the lateral distance between the second clamper 60 and the first clamper 40 is 800mm-1200mm; the lateral distance between the second clamper 60 and the detection module 50 is 650mm-700mm, that is, the lateral distance between the cigarette pack detection position and the second clamper 60 is 650mm-700mm.

[0071] Preferably, the detection module 50 is a photoelectric sensor.

[0072] The use process of the tooling of the present invention is as follows:

[0073] When the cigarette packs fill the conveying channel, the photoelectric sensor detects that there are cigarette packs at the cigarette pack detection position for more than 2 seconds. The control module controls the solenoid valve and the pipeline to input compressed air into the air bag of the second clamper, and the movable extrusion plate is pushed out through the air bag, thereby pushing the cigarette packs onto the movable extrusion plate to achieve friction fixation of the cigarette packs, so that the stacking pressure of the upstream cigarette packs is fully or partially offset by the friction force of the second clamper on the cigarette packs, thereby achieving the purpose of reducing the stacking pressure of the downstream cigarette packs.

[0074] like Figure 3 As shown, the cooperation between the positioning protrusion and the stop block plays a role in controlling the extension distance of the movable extrusion plate to prevent the cigarette package from being subjected to excessive extrusion force; the guide frame not only guides the lateral movement of the cigarette package, but also guides the longitudinal movement of the movable extrusion plate.

[0075] The control logic of the second clamper is: when the photoelectric sensor at the cigarette pack detection position continuously detects a cigarette pack for more than 2 seconds, the PLC controls the amplifier to drive the solenoid valve to switch direction, thereby inputting compressed air into the airbag of the second clamper to achieve friction fixation of the cigarette pack; when the photoelectric sensor at the cigarette pack detection position outputs no cigarette pack information, the PLC controls the amplifier to drive the solenoid valve to switch direction, thereby achieving the output of compressed air in the airbag; at the same time, a pressure reducing valve is provided on the pipeline at the input end of the airbag to control the pressure of the compressed air.

[0076] Compared with the prior art, this application has at least the following beneficial technical effects:

[0077] The present application applies an extrusion pressure in the longitudinal direction to the middle part of the cigarette pack belt that is laterally squeezed inside the conveying channel, so that the cigarette packs in the conveying channel generate a dynamic friction force opposite to the transverse extrusion force, thereby reducing the transverse extrusion pressure of the upstream cigarette packs on the downstream cigarette packs, ensuring that the transverse extrusion pressure of the cigarette packs at the separation drum is within the allowable range, ensuring that the cigarette packs are in good posture and smoothly conveyed.

[0078] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
