Abstract
The utility model provides a photoelectric induction alarming device which is arranged between a workpiece feeding zone and a workpiece removing zone of a coating production line. The utility model comprises two power supply input terminals used for connecting AC power supplies, a photoelectric sensor, a relay and an alarm, wherein the control ends of the photoelectric sensor and the relay are connected in series to form a first branch circuit, a normal open contact switch of the relay is connected with the alarm to form a second branch circuit, and the first branch circuit and the second branch circuit are connected in parallel to be coupled between the two power supply input terminals. When the optoelectronic induction alarming device inducts the pass of goods, an electric bell in a return circuit tweets to make workers hear the alarm to exclude exception in time. The utility model effectively prevents the fatal bad quality caused by coating for two times.
Description
[technical field]
The utility model relates to a kind of optoelectronic induction warning device, relates in particular to a kind of optoelectronic induction warning device that is used for the external coating field.
[background technology]
At present, be coated with to be contained in the plastic cement surface treatment and use more and more widely.Following technology is adopted in application usually: primer painting → intermediate layer paint application → finish paint application.Must strictness carry out in this order during painting operation, finish simultaneously can not weigh second time after this technology, otherwise second time adhesive force of coatings is very little, very easily comes off in the product use again, it is bad to produce great quality.And there is following defective in existing enclosed application transfer matic: when last (will treat that the application product uploads to paint line) and part (the application finished product is taken off from paint line) when process operations person leaves the post down, because last district (will treat that the application product uploads to the zone of paint line, that promptly treats the application product puts the zone temporarily) and following part district (with the application finished product from zone that paint line manually takes off, the product that promptly has been coated put the zone temporarily) adjoining, be coated with a small amount of finished product that installs and may ash be mixed last district, cause and enter paint booth once more by the application second time, this a small amount of defective products is mixed in a large amount of non-defective units, extremely difficulty is found, and has only to show that this is bad after the product assembling listing.
[summary of the invention]
The purpose of this utility model is exactly the shortcoming that exists in the existing application transfer matic in order to overcome, and avoids great quality bad, and a kind of optoelectronic induction warning device is provided, and prevents the application product by twice application, thereby causes great quality bad.
For achieving the above object, the utility model proposes a kind of optoelectronic induction warning device, be used to be arranged between the last part district and following part district of paint line, comprise two power input terminals, photoelectric sensor, relay and alarms being used to connect AC power, the control end series connection back of described photoelectric sensor and relay constitutes first branch road, the normally opened contact switch of described relay and alarm series connection back constitute second branch road, are coupling between two power input terminals after first branch road and the second branch road parallel connection.
Further, also comprise the reset switch that is connected between the parallel branch that one of them power input terminal and first branch road, second branch road form after in parallel.
Further, in described second branch road in an end of the normally opened contact switch of approach relay and first branch road end near photoelectric sensor be connected, the series connection contact of described relay normally open contact switch and alarm links to each other with the series connection contact of photoelectric sensor and relay control end.
So the beneficial effects of the utility model are: 1) the technical program is on the basis of existing application automation equipment, between last part district and following part district, add an optoelectronic induction warning device, when sensing goods through out-of-date, the loop of photoelectric sensor is connected, and is the relay coil power supply.After relay control circuit was connected, the normally opened contact closure had been connected its work loop, the warning that pipes of the electric bell in the loop.Hear that the back staff that reports to the police in time goes to get rid of unusually, has prevented effectively owing to twice application causes great quality bad.2) between power input terminal and photoelectric sensor, relay and the alarm reset switch is set therein, makes after abnormal conditions are excluded, can pass through manual reset, make the optoelectronic induction warning device can recover normal state, continue to survey.3) end with relay normally open contact switch and relay is connected, and constitutes self-locking circuit, further guarantees the reliability of optoelectronic induction warning device.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 is the circuit diagram of a kind of embodiment of the present utility model;
Fig. 2 is the circuit diagram of another kind of embodiment of the present utility model.
[embodiment]
Embodiment one, as shown in Figure 1, the control end of photoelectric sensor C and relay K A (being coil-end) series connection back constitutes first branch road 1, the normally opened contact K switch A1 of relay K A and alarm DL series connection back constitute second branch road 2, the reset switch TA that connects again after first branch road 1 and 2 parallel connections of second branch road is connected between two power input terminals then.Alarm DL can be electric bell or hummer.The AC220V power supply is whole warning device power supply through master switch HK control.Wherein reset switch TA can link to each other with any one terminal in two power input terminals whole warning device is resetted, and reset switch TA is in closure state under the normal condition.Whether photoelectric sensor C is used for detecting has article to pass through, and promptly is coated product through out-of-date when sensing article, and photoelectric sensor C connects, and makes first branch road 1 and two power input terminals constitute the loop, and relay coil gets.After relay control circuit was connected, the normally opened contact closure made second branch road 2 and two power input terminals formation loops, the warning that pipes of the electric bell in the loop.Hear that the back staff that reports to the police in time goes to get rid of unusually, and open the reset switch releasing and report to the police.Can press reset switch afterwards again makes the electro-induction warning device be in normal acquisition mode.
Embodiment two, as shown in Figure 2, end near photoelectric sensor C in the end of the normally opened contact K switch A1 of different with embodiment one is approach relay KA in second branch road 2 and first branch road 1 is connected, and the series connection contact of relay normally open contact K switch A1 and alarm DL links to each other with the series connection contact of relay K A control end with photoelectric sensor C.In case after the normally opened contact K switch A1 of relay K A closure, be connected between two power input terminals after the coil series connection of normally opened contact K switch A1 and relay K A, constitute self-locking circuit, even photoelectric sensor C disconnects, first branch road 1 no longer constitutes the loop with two power input terminals, because of 2 energisings of second branch road, thereby relay K A is continued under the connection of normally opened contact K switch A1, it is closed that normally opened contact K switch A1 is continued, alarm continues to pipe, have only when manually opening reset switch TA, alarm just cuts off the power supply.Thereby make relay K A not be subjected to the influence of photoelectric sensor C, make whole warning device more reliable.
The utility model not only can be applicable to field of coating, and any needs prevent that the area entry that article enter from all can use this programme, enter unusually to prevent article.
