Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without any inventive step, are intended to be within the scope of the present disclosure.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
In the description of the present disclosure, it is to be understood that the terms "central," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the scope of the invention.
In the description of the present disclosure, it should be understood that the terms "first", "second", etc. are used to define the components, and are used only for convenience of distinguishing the corresponding components, and if not otherwise stated, the terms have no special meaning, and thus, should not be construed as limiting the scope of the present disclosure.
The inventor finds out through research that the reason that the power consumption of the existing tobacco production system is large is mainly as follows: the production process of the tobacco production system is continuous, and generally the material is transferred from one buffer unit to another buffer unit and processed in the process. In order to avoid material blockage, the production line equipment is started in the reverse direction of material conveying, namely, the equipment behind the material flow is started first and then the equipment in front is started. When the production line is started, the equipment is started from back to front, and after all the equipment is operated, the materials are conveyed to a destination from a storage place; and after the production is finished, stopping the operation of the whole-line equipment after all the materials reach the destination.
Because the line of each control process section is longer, the time from the production of the material starting end to the tail end is longer, the front equipment is always in load operation at the beginning of production, and the rear equipment is always in no-load operation; and in the later stage of production, the rear equipment is loaded and operated, and the front equipment is unloaded and operated. This results in a waste of energy and also increases the losses of the equipment. From the above start-up and stop laws of the plant in the production process, there are two situations that can cause the plant to idle:
1) when the production is started or the material head is broken, the equipment which does not reach the material can idle;
2) when production is finished or tailing is broken, the equipment through which the material passes idles.
For example, when production starts and ends, there is a stub bar and a stub bar, and a material break means that equipment is shut down due to some fault in batch production, the batch of materials is interrupted, and the equipment needs to be restarted to resume production, and the stub bar at this time are called a material break stub bar and a material break tail.
Therefore, in order to achieve the purpose of energy saving under the condition that the process and equipment of the tobacco production system are not changed, the method is one of the approaches for improving the effective operation rate of the equipment by reducing the idle time of the equipment.
Based on this improved idea, the present disclosure provides a tobacco production system, as shown in fig. 1 to 3, comprising, in some embodiments:
the main production equipment is used for processing tobacco materials and is provided with an outlet gathering vibration groove 1;
the auxiliary joint equipment is positioned between two adjacent main production equipment and is connected with the outlet gathering vibration groove 1 of one main production equipment;

For example, the main production equipment may include at least one of the material loosener 10, the material cutter 18 and the feeder 27, and after the tobacco material is processed, the processed tobacco material is output through the outlet collection vibratory trough 1.
The auxiliary joint equipment is positioned between two adjacent main production equipment and used for conveying tobacco materials, one end of the auxiliary joint equipment is connected with the outlet gathering vibration groove 1 of one main production equipment, and the other end of the auxiliary joint equipment is connected with the inlet of the other main production equipment. For example, the auxiliary coupling device may include at least one of a vibrating conveyor, a belt conveyor, and a storage bin. The belt conveyor may be a one-way or two-way belt conveyor.
The shooting component 3 can be a camera or the like, and the shooting component 3 can be arranged above or on the side of the outlet collection vibration groove 1 and used for detecting whether tobacco materials exist in the outlet collection vibration groove 1. The material conveying position can be detected by adding visual detection, and the time of the head and the tail of the material is judged reasonably, so that the purpose of accurately confirming the material conveying state is finally achieved. For example, the photographing part 3 may detect the flow rate of the material.
This embodiment gathers through shooting part 3 and shakes whether there is the tobacco material in groove 1 in the export of main production equipment to accurately judge the opportunity of opening of this main production equipment low reaches a set of auxiliary union equipment, only gather at the export and shake and just open a set of auxiliary union equipment in low reaches under the condition that has the tobacco material in groove 1, can solve the problem that the idle running of process equipment unnecessary was waited for material in the tobacco production system production process, improved the use efficiency of tobacco production system equipment on the basis of reducing the energy consumption, energy saving and consumption reduction fine control ability in the promotion tobacco processing process, reach more energy-conserving intelligent production control mode.
In some embodiments, as shown in fig. 1, the camera 3 is mounted above the outlet collection vibratory trough 1.
For example, the tobacco production system further includes a support 2, the support 2 may span from above the outlet collection vibratory trough 1, and the photographing part 3 may be mounted on a portion of the support 2 located above the outlet collection vibratory trough 1.
Alternatively, the photographing part 3 may be provided at a side portion of the outlet collective vibration tank 1.

In some embodiments, the controller 4 is configured to delay stopping a set of auxiliary devices connected to the outlet aggregate vibratory trough 1 in the tobacco material conveying direction in the case where the photographing part 3 detects that there is no tobacco material in the corresponding outlet aggregate vibratory trough 1.
In the embodiment, under the condition that the shooting component 3 detects that no tobacco material exists in the corresponding outlet collection vibration groove 1, no material is output in the main production equipment where the outlet collection vibration groove 1 is located, the auxiliary connection equipment is closed, the energy consumed by the work can be reduced, and the energy-saving effect is achieved. The delayed stop can ensure that the current tobacco material in the outlet gathering vibration groove 1 is conveyed completely.
Therefore, the tobacco production system can accurately control the start and stop of each group of auxiliary joint equipment, can ensure the smooth operation of the tobacco production process, can solve the problem of unnecessary idle waiting of the auxiliary joint equipment in the production process, improves the use efficiency of the tobacco production system equipment, and achieves a more energy-saving intelligent production control mode.
In some embodiments, the tobacco production system further comprises a mode switching component configured to selectably place the tobacco production system in a normal control mode or an energy-saving control mode; wherein, in the energy saving control mode, the controller 4 is configured to assist the start and stop of the associated apparatus according to the detection result of the photographing part 3.

In the starting process of the multi-group auxiliary connection equipment, the equipment is started according to the reverse sequence of the logistics direction, namely the equipment which is far away from the material is started first, so that the problem of material blockage is avoided. When the production line is started, the equipment is started from back to front, and after all the equipment is operated, the materials are conveyed to a destination from a storage place; and after the production is finished, stopping the operation of the whole-line equipment after all the materials reach the destination.
Because the circuit of each control process section is longer, the production from the starting end of the material to the tail end of the material needs longer time, the front equipment is in load operation at the beginning of the production, and the rear equipment is in no-load operation; and in the later stage of production, the rear equipment is in loading operation, and the front equipment is in no-load operation. This results in a waste of energy and also increases the losses of the equipment. Therefore, the energy-saving control mode can be used for starting and stopping along with the conveying condition of the material, the no-load running time of the equipment is shortened, and the equipment loss is reduced.
The tobacco production equipment of the embodiment can be selectively switched between a conventional control mode and an energy-saving control mode, and can select a proper control mode according to the actual production situation, so that the original control mode is reserved, and a new energy-saving control mode is independently added. For example, in the case where the continuity of the conveyance of the tobacco material is good, the normal control mode is preferentially selected, and in the case where the conveyance of the tobacco material is intermittent, the energy-saving control mode is preferentially selected.
In some embodiments, a plurality of master production devices are configured to run continuously during the production process. Wherein, the main production equipment and the outlet gathering vibration tank 1 thereof run continuously.

In some embodiments, the auxiliary joining apparatus includes: at least one of a belt conveyor, a vibrating conveyor, and a storage cabinet.
When the same group of auxiliary connection equipment needs to be started, all the equipment in the auxiliary connection equipment is started in sequence along the reverse direction of the conveying direction of the tobacco materials, namely, the equipment behind the logistics is started first and then the equipment in front is started, so that the tobacco material blockage of downstream equipment is avoided when the upstream equipment fails.
When the material quantity required by the downstream main production equipment is less than the material quantity output by the adjacent upstream main production equipment, a storage cabinet can be arranged between the adjacent main production equipment to cache the material.
This embodiment sets up between adjacent main production facility and assists allies oneself with equipment, can realize the smooth transport of material, guarantees that the tobacco production process goes on smoothly.
In some embodiments, as shown in fig. 2, the tobacco production system further comprises a distributed IO device 5 configured to receive the shooting information of the shooting component 3 and send the shooting information to the controller 4.
