Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, in particular to a cigarette flow balance conveying device. Background Art

[0002] In the cigarette production process, the rolling and packaging connection equipment is used as a cigarette storage and conveying equipment to convey the cigarettes produced by the cigarette making machine to the packaging machine. During the cigarette conveying process, the consistency and stability of the cigarette height must be ensured, otherwise it is easy to cause disorderly cigarettes and blockage, thus affecting the feeding into the cigarette storage device. CN212556929U provides a material level control system for a cigarette lifting channel. A detection grating is used to detect the material level height of the feeding port of the lifting channel, and then the speed of the lifting conveyor belt is corrected by a proportional regulator to ensure that the amount of cigarettes in the horizontal conveying section and the lifting conveying section is at an appropriate material level height, so that there is no large gap at the bend of the lifting conveying section, thereby ensuring the smooth transportation of cigarettes at the lifting section without sliding down and avoiding disorderly cigarettes and blockage.

[0003] In fact, the wrapping connection equipment not only needs to ensure smooth transportation at the lifting point, but also needs to pay attention to the congestion and disorder of cigarettes in the cigarette storage. Specifically, when the speed of the cigarette storage to the downstream machine is less than the speed of the cigarette oblique conveyor feeding into the cigarette storage, it will cause the cigarettes to pile up in the cigarette storage, and then there will be problems of uneven height and blockage of cigarettes, which will also increase the number of shutdowns of the upstream machine. When the speed of the cigarette storage to the downstream machine is greater than the speed of the cigarette oblique conveyor feeding into the cigarette storage, the material level value of the cigarettes in the cigarette storage will reach the lower limit, which will also increase the number of shutdowns of the downstream machine.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The utility model aims to provide a cigarette flow balance conveying device in view of the deficiencies of the prior art.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A cigarette flow balance conveying device, comprising:

[0008] A cigarette elevator, the outlet of which is connected to the inlet of the overhead conveyor;

[0009] An overhead conveyor, the outlet of which is connected to the inlet of the cigarette oblique conveyor;

[0010] An oblique cigarette conveyor, the outlet of which is connected to the inlet of the cigarette storage;

[0011] Cigarette storage device, used for storing and transporting cigarettes;

[0012] The first distance sensor is arranged at the connection between the cigarette elevator and the elevated conveyor, and is used to collect the height of cigarettes at the connection between the cigarette elevator and the elevated conveyor;

[0013] A first adjustment control unit communicates with the first distance sensor and the PLC controller, and is used to send an adjustment instruction I to the PLC controller when the height of the cigarette collected by the first distance sensor is greater than a height threshold I;

[0014] The second distance sensor is arranged at the connection between the cigarette oblique conveyor and the cigarette storage, and is used to collect the height of the cigarettes in the cigarette storage;

[0015] A second adjustment control unit communicates with the second distance sensor and the PLC controller, and is used to send an adjustment instruction II to the PLC controller when the height of the cigarette collected by the second distance sensor is greater than a height threshold II;

[0016] The PLC controller is respectively connected to the cigarette elevator and the cigarette storage control, and is used to control the running speed of the lower lifting belt of the cigarette elevator according to the adjustment instruction I and to control the running speed of the conveyor belt motor of the cigarette storage according to the adjustment instruction II.

[0017] The present invention has substantial features and progress compared to the prior art. Specifically, the present invention uses a first distance sensor to send a cigarette height signal at the connection between a cigarette elevator and an elevated conveyor, and after receiving the cigarette height signal, the controller controls the running speed of the lower lifting belt of the cigarette elevator to prevent cigarettes from stacking in the elevated conveyor section, thereby ensuring the consistency of cigarette height in the elevated conveyor section; a second distance sensor is used to detect the cigarette height signal in a cigarette storage, and after receiving the cigarette height signal, the controller controls the running speed of the conveyor belt motor of the cigarette storage to prevent cigarettes from stacking in the cigarette storage device, thereby ensuring the consistency of cigarette height in the cigarette storage device.

[0022] Flow diagram of the traditional YF17 cigarette storage. The roll-pack connection device acts as a storage container, dynamically matching the speed difference between the upstream and downstream machines, so that the cigarettes form a continuous flow in the channel, ensuring the supply and demand of cigarettes for the upstream and downstream machines and their continuous operation.

[0023] Since the amount of stored cigarettes is limited, when the material level reaches the upper and lower limit values, the storage and conveying functions of the wrapping connection equipment are lost, causing the upstream or downstream machine to shut down. This requires the cigarette factory operators to operate the upstream and downstream machines to restart them, which increases the workload and causes material loss.

[0024] There are many reasons why the material level value reaches the upper and lower limits, such as the mismatch between the speed at which the cigarette storage device conveys cigarettes to the downstream machine and the speed at which the cigarette oblique conveyor feeds cigarettes into the cigarette storage device.

[0025] In order to solve the above problems, the present application uses the height of cigarettes collected by distance sensors, and controls the speed of the cigarette storage and cigarette elevator according to the height of the cigarettes, thereby ensuring that the height of the cigarettes in the storage of the rolling and packaging connection equipment is stable and consistent, avoiding the phenomenon of disorderly cigarettes, thereby reducing the number of shutdowns of the cigarette making machine and packaging machine.

[0026] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0027] Example 1

[0028] This embodiment provides a cigarette flow balance conveying device, such as Figure 1-3 As shown, including:

[0029] The cigarette elevator 3, whose outlet is connected to the inlet of the overhead conveyor 6;

[0030] An overhead conveyor 6, whose outlet is connected to the inlet of the cigarette oblique conveyor 7;

[0031] The outlet of the oblique cigarette conveyor 7 is connected to the inlet of the cigarette storage 5;

[0032] The cigarette storage device 5 is used to store and transport cigarettes. Specifically, the cigarette storage device should not only be able to transport cigarettes, but also be able to automatically adjust its own cigarette storage capacity according to the operating conditions of the upstream and downstream machines, so as to achieve compensation and adjustment of cigarettes on the production line, that is, to achieve dynamic storage. In order to dynamically store, the existing cigarette transport storage device is provided with a dynamic storage and delivery mechanism, such as a storage and transport method with a cylindrical spiral structure, that is, the conveyor belt is arranged and installed in the space in the form of a cylindrical spiral line;

[0033] The first distance sensor 1 is arranged at the connection between the cigarette elevator 3 and the overhead conveyor 6, and is used to collect the height of cigarettes at the connection between the cigarette elevator 3 and the overhead conveyor 6;

[0034] A first adjustment control unit, used to send an adjustment instruction I to the PLC controller when the cigarette height collected by the first distance sensor 1 is greater than a built-in height threshold I;

[0035] The second distance sensor 2 is arranged at the connection between the cigarette oblique conveyor 7 and the cigarette storage 5, and is used to collect the height of the cigarettes in the cigarette storage 5;

[0036] A second adjustment control unit, used to send an adjustment instruction II to the PLC controller when the cigarette height collected by the second distance sensor 2 is greater than a built-in height threshold II;

[0037] The PLC controller is respectively connected to the first adjustment control unit, the second adjustment control unit, the cigarette elevator 3, and the cigarette storage 5, and is used to control the running speed of the lower lifting belt 4 of the cigarette elevator 3 according to the adjustment instruction I, and is used to control the running speed of the conveyor belt motor of the cigarette storage 5 according to the adjustment instruction II.

[0038] In a specific implementation, the second regulating control unit and the first regulating control unit may both adopt the proportional regulator described in CN212556929U, or may adopt other controllers, which will not be described in detail here.

[0039] In a specific implementation, both the first distance sensor 1 and the second distance sensor 2 are reflective optical sensors. The first distance sensor 1 is fixed to the top of the connection between the cigarette elevator 3 and the overhead conveyor 6 through a first bracket; the second distance sensor 2 is fixed to the side of the connection between the cigarette oblique conveyor 7 and the cigarette storage 5 through a second bracket.

[0040] The first bracket is a T-shaped bracket, the longitudinal plate of the T-shaped bracket is vertically fixed to the top of the connection between the cigarette elevator 3 and the overhead conveyor 6, and the first distance sensor 1 is arranged on the transverse plate of the T-shaped bracket;

[0041] The second bracket is an L-shaped bracket, the longitudinal plate of the L-shaped bracket is fixed to the side of the connection between the cigarette oblique conveyor 7 and the cigarette storage 5, and the second distance sensor 2 is arranged on the transverse plate of the L-shaped bracket.

[0042] Furthermore, in order to facilitate disassembly, the longitudinal plate of the T-shaped bracket is fixedly connected to the top of the connection between the cigarette elevator 3 and the overhead conveyor 6 by nuts, and the first distance sensor 1 is fixedly connected to the transverse plate of the T-shaped bracket by nuts; the longitudinal plate of the L-shaped bracket is fixed to the side of the connection between the cigarette oblique conveyor 7 and the cigarette storage 5 by nuts, and the second distance sensor 2 is fixed to the second transverse mounting plate by nuts.

[0043] The working process of the utility model is as follows: after the cigarette elevator 3 transports the cigarettes to the overhead conveyor 6, the first distance sensor 1 will sense the cigarettes and send them to the first adjustment control unit. At this time, the first adjustment control unit will compare the cigarette height collected by the first distance sensor 1 with the built-in height threshold I. When the collected cigarette height is greater than the built-in height threshold I, it triggers the sending of an adjustment instruction I to the PLC controller, and the PLC controller controls the lower lifting belt 4 of the cigarette elevator 3 to reduce or increase the running speed.

[0044] As the oblique cigarette conveyor 7 runs, the cigarettes will enter the cigarette storage. At this time, the second distance sensor 2 senses the cigarettes and sends them to the second adjustment control unit. The second adjustment control unit compares the cigarette height collected by the second distance sensor 2 with the built-in height threshold II. When the collected cigarette height is greater than the built-in height threshold II, the adjustment instruction II is triggered to be sent to the PLC controller. The PLC controller controls the running speed of the conveyor belt motor in the cigarette storage, so that the cigarette height of the cigarette storage 5 of the rolling and packaging connection device is stable and consistent, avoiding the phenomenon of messy cigarettes, thereby reducing the number of shutdowns of the cigarette making machine and the packaging machine.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
