Abstract
The utility model discloses a speed-collecting device for a glass washer and a glass washer, wherein the speed-collecting device comprises a speed display meter; and the speed display meter is electrically connected with an analog output terminal of a frequency converter of the glass washer, and obtains and displays speed values of the glass washer according to electrical signals output by the analog output terminal. In the utility model, the speed display meter is connected with the analog output terminal of the frequency converter; therefore, transmission speed of glass in the washer can be precisely tested and displayed, thus further obtaining the main transmission speed of the glass washer, not only saving speed-detecting elements, reducing equipment cost, but also having simple wiring and easy implement, and reducing trouble sources of equipment.
Description
Technical field
The utility model relates to glass art, in particular to a kind of speed acquisition device and glass cleaning machine that is used for glass cleaning machine.
Background technology
The main transmission speed acquisition and the display mode of at present domestic and international glass cleaning equipment are to adopt measuring elements such as encoder and inductive switch to detect main transmission roller-way speed mostly, and then show by speed measuring instrument.This mode need adopt the speed measuring element, has not only increased equipment cost, has increased the source of trouble that equipment may occur (equipment operation for some time measuring element may become flexible or damage) simultaneously.
The utility model content
The utility model provides a kind of speed acquisition device and glass cleaning machine that is used for glass cleaning machine, has realized the collection to glass cleaning machine main transmission speed signal under the prerequisite that does not need the speed measuring element.
According to an aspect of the present utility model, a kind of speed acquisition device that is used for glass cleaning machine is provided, this speed acquisition device comprises: the speed display instrument, it is electrically connected with analog output of the frequency transformer of glass cleaning machine, obtains and show the speed numerical value of glass cleaning machine according to the electrical signal of analog output output.
Preferably, above-said current signal is the analog output voltage signal.
Preferably, above-said current signal is the analog output current signal.
According to another aspect of the present utility model, a kind of glass cleaning machine also is provided, it has above-mentioned speed acquisition device.
The foregoing description is by being connected the speed display instrument with analog output of frequency transformer, can accurately measure and show the transfer rate of glass in cleaning machine, be the main transmission speed of glass cleaning machine, not only saved the speed measuring element, reduced equipment cost, wiring simultaneously is simple, implements easily, has reduced the equipment failure source.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the speed acquisition device wiring schematic diagram that is used for glass cleaning machine according to an embodiment of the utility model.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not paying the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
At first principle of the present utility model is set forth.Speed control by frequency variation is adopted in current glass cleaning machine main transmission more, frequency transformer is an existing control device in the glass cleaning machine Controlling System, be varied to direct ratio with its output frequency (being the frequency transformer analog output signal is directly proportional with supply frequency on being added to motor and the frequency transformer analog output signal is strong and weak, that is to say that the frequency transformer analog output signal is directly proportional with motor speed, and cleaning machine main transmission speed is directly proportional with motor speed).So speed signal is directly got from frequency transformer, and the frequency transformer analog output signal that will be directly proportional with frequency is received on the instrument, becomes speed numerical value (V=af+b by calculating conversion, wherein V is a speed, and f is the frequency of analog output signal, and a is a scale-up factor, a＞0, b is a modified value.B=0 under the normal circumstances sets the b value and is revised when displayed value and actual value have error) show.That is to say the signal detection component that to gather way, just can realize the collection of speed signal.
Fig. 1 is the speed acquisition device wiring schematic diagram that is used for glass cleaning machine according to an embodiment of the utility model.As shown in Figure 1, frequency transformer analog output voltage or current signal are received on the speed display instrument, in the speed display instrument, set multiplying power and modified value, become speed numerical value (V=af+b) through the calculating conversion and show from frequency transformer analog output.
The transfer rate of glass in cleaning machine can accurately be measured and show to present embodiment, i.e. the main transmission speed of glass cleaning machine by this mode of connection, not only saved the speed measuring element, reduced equipment cost, wiring simultaneously is simple, implement easily, reduced the equipment failure source.
One of ordinary skill in the art will appreciate that: accompanying drawing is the synoptic diagram of an embodiment, and module in the accompanying drawing or flow process might not be that enforcement the utility model is necessary.
One of ordinary skill in the art will appreciate that: the module in the device among the embodiment can be described according to embodiment and be distributed in the device of embodiment, also can carry out respective change and be arranged in the one or more devices that are different from present embodiment.The module of the foregoing description can be merged into a module, also can further split into a plurality of submodules.
Above-mentioned the utility model embodiment sequence number is not represented the quality of embodiment just to description.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that previous embodiment is put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of the utility model embodiment technical scheme.
