Accompanying drawing explanation
To describe preferred embodiment in the utility model in detail by accompanying drawing below, will contribute to understand the purpose of this utility model and advantage, wherein:
Fig. 1 is the connection diagram that the utility model prevents the device of chute blocking;
Fig. 2 is the installation site schematic diagram of the utility model photoelectric switch of preventing the device of chute blocking.
The specific embodiment
Fig. 1 is the connection diagram that the utility model prevents the device of chute blocking.As shown in Figure 1, the device that prevents chute blocking comprises photoelectric switch 1 and controller 2, and wherein, whether described photoelectric switch 1 reaches predetermined altitude value for detection of material in chute, and when height of materials reaches predetermined value in described chute, send electric signal to described controller 2; Described controller 2 receives the electric signal from described photoelectric switch 1; and send halt instruction according to described electric signal to charging (feeding) equipment 3; the input end of described controller 2 is connected with the receiving end 5 of described photoelectric switch 1; the mouth of described controller 2 is connected with the switch of described charging (feeding) equipment 3; preferably; the mouth of described controller 2 can be connected to the motor switch of described charging (feeding) equipment 3; thereby can be in the time that described chute 6 stops up; the electrical motor of directly controlling described charging (feeding) equipment 3 shuts down, and reaches the object of shutdown.
As shown in Figure 1, described photoelectric switch 1 comprises transmitting terminal 4 and receiving end 5, and described transmitting terminal 4 is for sending photosignal, the photosignal that described receiving end 5 sends for receiving described transmitting terminal 4.Fig. 2 is the installation site schematic diagram of the utility model photoelectric switch of preventing the device of chute blocking, the service direction that wherein W direction is material.As shown in Figure 2, described transmitting terminal 4 and receiving end 5 are oppositely arranged on the inwall of described chute 6.Preferably, it is highly identical that described transmitting terminal 4 and receiving end 5 arrange, and described transmitting terminal 4 and receiving end 5 are separately positioned on two relative inwalls of described chute 6.
The transmitting terminal 4 of described photoelectric switch 1 is for sending optical signal (as infrared ray), the optical signal that the receiving end 5 of described photoelectric switch 1 sends for receiving described transmitting terminal 4.In the situation that described chute 6 normal operations do not stop up; described receiving end 5 can normally receive the optical signal that described transmitting terminal 4 sends; now; described receiving end 5 does not send electric signal to described controller 2; described controller 2 does not also send halt instruction to described charging (feeding) equipment 3; described charging (feeding) equipment 3 normal operations, described chute 6 is also normally worked.
In the time there is the situation of obstruction in described chute 6, described chute 6 is inner can pile up certain material, in the time that solid accumulation height arrives the position of the optical signal that described transmitting terminal 4 sends, the stacked material of described optical signal blocks, and described receiving end 5 just cannot be received the optical signal that described transmitting terminal 4 sends.Now; described receiving end 5 sends electric signal to described controller 2; described controller 2 is received after the electric signal from described receiving end 5; send halt instruction to described charging (feeding) equipment 3; described charging (feeding) equipment 3 quits work; stop adding materials to described chute 6, now need staff by manually start operation again again after being deposited in material in described chute 6 and cleaning out.
In a preferred embodiment, described controller 2 can pass through PLC or chip microcontroller.
Preferably, after stopping up at described chute 6, remind staff to clear up stacking material, the device that prevents chute blocking described in the utility model is also included in when described chute 6 stops up and sends the annunciator of warning, and described annunciator is connected with the mouth of described controller 2.
Preferably, described annunciator can be indicator lamp, and in the time that the situation of obstruction occurs described chute 6, described chute 6 is inner can pile up certain material, in the time that solid accumulation height arrives the position of the optical signal that described transmitting terminal 4 sends, the stacked material of described optical signal blocks.Now, described receiving end 5 just cannot be received the optical signal that described transmitting terminal 4 sends, and described receiving end 5 sends electric signal to described controller 2, and described controller 2 is received after the electric signal from described receiving end 5, sends halt instruction to described charging (feeding) equipment 3.Meanwhile, described controller 2 also sends electric signal to described indicator lamp, and described indicator lamp is opened, and for pointing out staff to clear up the material of accumulation, enhances productivity.
Preferably, described annunciator can also use read-out, in the time that described chute 6 occurs to stop up, described controller 2 sends halt instruction to described charging (feeding) equipment 3, send electric signal to described indicator lamp indicator lamp is opened, also send signal to described read-out simultaneously, described read-out, according to show relevant captions promptings (as captions such as " equipment is stopped transport; please process in time " or " chute blockings ") from the signal of described controller 2, reminds staff to clear up stacking material.
Preferably, when described annunciator is selected indicator lamp, described indicator lamp can also be connected to the current output terminal on the receiving end 5 of described photoelectric switch 1.When situation about stopping up occurs described chute 6, when solid accumulation height arrives the position of the optical signal that described transmitting terminal 4 sends, the stacked material of described optical signal blocks, described receiving end 5 just cannot be received the optical signal that described transmitting terminal 4 sends, now described receiving end 5 also sends electric signal to described indicator lamp in the time that described controller 2 sends electric signal, indicator lamp is started, remind staff to clear up stacking material.
In order to prevent that material from accidentally blocking the optical signal that described transmitting terminal 4 sends and the shutdown causing; avoid the fugitiveness of equipment; preferably; in described controller 2, certain setting time is set; the electric signal sending when described receiving end 5 continues set setting time; described controller 2 just sends halt instruction to described charging (feeding) equipment 3, has so just improved the stability of device.
Although the utility model illustrates and describes with reference to its preferred embodiment, but will be understood by those skilled in the art that, in the case of not departing from the spirit and scope of the present utility model that the appended claims limit, can carry out the various changes of form and details.
