Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco production equipment, in particular to a safe conveying control circuit for a tobacco conveyor. Background Art
[0002] In the current tobacco production environment, tobacco leaves are harvested, processed, and finally transformed into products, all of which are inseparable from the conveyor line. In tobacco factories, due to the various types of workers at work, the tobacco conveyor sometimes requires staff to be careful to avoid accidents. Therefore, a safety reminder procedure is required before the conveyor line officially begins operation. Currently, tobacco production lines do not have such safety reminder auxiliary devices. Utility Model Content
[0003] In view of this, the purpose of the present invention is to provide a safe conveying control circuit for a tobacco conveyor, which sets a safety prompt step before the production line is started to effectively reduce the potential safety accidents.
[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a safe conveying control circuit for a tobacco conveyor, including a control circuit for controlling the operation of the tobacco conveyor, adding a time relay KT and an intermediate relay KA to the original control circuit for controlling the operation of the tobacco conveyor; including a stop button SB1 and a start button SB2; the stop button SB1 is connected to a 36V power supply and connected to the start button SB2, the start button SB2 also includes a first contact and a second contact, the first contact and the second contact are connected to the intermediate relay KA, the time relay KT is connected to the intermediate relay KA, and the time relay KT is connected to a buzzer B.
[0005] In a preferred embodiment, the time relay KT is provided with a safety reminder time.
[0006] In a preferred embodiment, the time relay KT includes a third contact and a fourth contact, and the intermediate relay KA includes a fifth contact and a sixth contact; the third contact is connected to the fifth contact, and the fourth contact is connected to the sixth contact and the second contact.
[0007] In a preferred embodiment, the intermediate relay KA is specifically Omron H3Y-2-C.
[0008] Compared with the prior art, the present invention has the following beneficial effects: the present invention provides a safe conveying control circuit for a tobacco conveyor, sets a safety reminder step before the production line is started, sets a safety reminder time through the intermediate relay KT, controls the buzzer to give a safety reminder, and after the safety reminder time has passed, the buzzer prompts, and the original control circuit for controlling the operation of the tobacco conveyor starts to be powered on and operate normally. This technical solution can effectively reduce the hidden dangers of safety accidents. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a circuit principle wiring diagram of a preferred embodiment of the utility model. DETAILED DESCRIPTION
[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0011] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.
[0012] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application; as used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form, and it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.
[0013] A safe conveying control circuit for tobacco conveyors, reference Figure 1 The control circuit for controlling the operation of the tobacco conveyor is a conventional control circuit for controlling the operation of the tobacco conveyor and is therefore not further described herein. A time relay KT and an intermediate relay KA are added to the conventional control circuit for controlling the operation of the tobacco conveyor. The control circuit also includes a stop button SB1 and a start button SB2. The stop button SB1 is connected to a 36V power supply and to the start button SB2. The start button SB2 also includes a first contact and a second contact 12, which are connected to the intermediate relay KA. The time relay KT is connected to the intermediate relay KA, and the time relay KT is connected to a buzzer B.
[0014] The time relay KT is provided with a safety reminder time, which can be set to 20 seconds, 30 seconds or other lengths of safety reminder time. A reminder sound is played through a buzzer to remind on-site staff that the tobacco conveyor line is about to start working to remind staff to pay attention to avoid it.
[0015] The time relay KT includes a third contact and a fourth contact, and the intermediate relay KA includes a fifth contact and a sixth contact; the third contact is connected to the fifth contact, that is, Figure 1 The contact numbered 13; the fourth contact connects the sixth contact and the second contact, that is, Figure 1 The contact numbered 14.
[0016] The intermediate relay KA is specifically Omron H3Y-2-C.
[0017] Modification Method: ① Extract 36V AC voltage from the original transformer to control the coils of time relay KT and intermediate relay KA, respectively, to enable starting and self-locking functions. ② Utilize one set of delayed closing contacts of time relay KT in series with the original stop button circuit to prevent the conveyor from starting within a set time. ③ Utilize another set of delayed opening contacts of KT in series with a buzzer to enable the buzzer to broadcast a message within a set time.
[0018] The utility model provides a safe conveying control circuit for a tobacco conveyor. By utilizing the control principle of the original secondary circuit of the conveyor, a time relay KT and an intermediate relay KA are added. Through the modification, the circuit can realize the functions of "voice broadcast", warning and delayed start of the conveyor belt.
