Brief description of the drawings

Embodiment of the present utility model is described below in conjunction with accompanying drawing, wherein：

A kind of structural representation of the control system for cloth spreading device that Fig. 1 provides for the utility model.

Fig. 2 is had the structural representation of limit switch by the control system of Fig. 1 cloth spreading device.

Embodiment

Specific embodiment of the utility model is further elaborated below based on accompanying drawing.It should be appreciated that herein Described specific embodiment is not used to limit protection domain of the present utility model only as embodiment.

Fig. 1 and Fig. 2 are referred to, a kind of structure of the control system 100 of its cloth spreading device provided for the utility model is shown It is intended to.The control system 100 of the cloth spreading device includes a paving cloth table 10, and one is arranged on the paving cloth spread on cloth table 10 Machine 20, one be arranged on the paving cloth table 10 one end limit switch 30, one is disposed relative to the limit switch 30 Paving cloth table 10 the other end drag-line fixing end 40, one is arranged between the limit switch 30 and drag-line fixing end 40 Drag-line 50, and a data processing module 60 controlled by the limit switch 30.It is envisioned that the cloth spreading device Control system 100 also include other functional modules, such as drive mechanism, data performing module, the electronic circuit such as electromagnetic relay, And data display screen etc., it is not utility model emphasis in the utility model known by those skilled in the art, This is no longer described in detail.

The paving cloth table 10 is a rectangle tables, and for placing cloth, layout machine 20, and other various productions are set It is standby, while being also the place of operative employee's work.The paving cloth table 10 is typically long, there is 30 meters to 50 meters.Certainly it has The length of body can be selected according to actual needs.

The layout machine 20 is a kind of plant equipment known by those skilled in the art, for example, it is included located at paving cloth Track, drive mechanism, the guide plate of the both sides of table 10, fabric axle, shear etc..The specific mechanical structure of layout machine 20 itself Just no longer described in detail herein with operation principle, but it can carry out paving cloth work under the commander of the data processing module 60, And also having can be closed down and starting switch with manually-operated.

The limit switch 30 is arranged on one end of the paving cloth table 10, it is contemplated that the limit switch 30 is set Terminal position on the length direction along the paving cloth table 10.The limit switch 30 includes a wheel disc 31, a setting Plug-in strip 32 on the wheel disc 31, the pull bar 33 that is arranged on the wheel disc 31, and one be used to make the pull bar 33 elastic components 34 resetted.In fig. 2, the structural representation of the limit switch 30 is only shown, is not the limit switch 30 pictorial diagram, it is contemplated that for the material object of the limit switch 30, it should also include shell, fixing device such as Screw, etc..To those skilled in the art, the structural representation provided according to the utility model, necessarily can basis It is actually needed and produces corresponding material object.The wheel disc 31 is fixed on paving cloth table 10 by central shaft, it is possible in this Heart axle rotates in the presence of external force.The plug-in strip 32 is all arranged on the wheel disc 31 with pull bar 33, and the plug-in strip 32 is with drawing Radial direction of the bearing of trend of bar 33 all with the wheel disc 31 is overlapped, while the pull bar 33 and the plug-in strip 32 are in the wheel disc 31 Deviation in the radial direction set.In other words, as the angle of the pull bar 33 and plug-in strip 32 between bearing of trend is more than 0 Degree.In the present embodiment, the angle between the bearing of trend of the pull bar 33 and plug-in strip 32 is more than 90 degree, so that described draw Bar 33 has different strokes from plug-in strip 32.The elastic component 34 is arranged on the free end of the pull bar 33, i.e., described wheel disc 31 The two ends of the pull bar 33 are separately positioned on elastic component 34.The other end of the elastic component 34 is fixed on the paving cloth table 10 On, specifically, the other end of the elastic component 34 is fixed on one end of its close end of the paving cloth table 10.The elastic component 34 can with a spring, and in the reset condition of the elastic component 34, i.e. unstretched state, the plug-in strip 32 with the data There is reason module 60 contact 61 to keep electrical contact.

The drag-line fixing end 40 is disposed relative on the other end of paving cloth table 10 of the limit switch 30, so as to So that any one position of operative employee on the length direction along the paving cloth table 10 can pull the drag-line 50.It is described to draw Rope fixing end 40 can be that can arbitrarily fix the structural member of the drag-line 50, and the method for its concrete structure or stationary rope is to this Art personnel can arbitrarily expect, just no longer illustrate herein.

One end of the drag-line 50 is fixed on the pull bar 33, and the other end is fixed in the drag-line fixing end 40, i.e., The pull bar 33 can be driven by pulling the drag-line 50 around the central axis of the wheel disc 31, so as to drive the wheel Disk 31 is rotated, and then drives the plug-in strip 32 to rotate, and depart from the plug-in strip 32 has contact with the data processing module 60 61 electrical contact.And when decontroling the drag-line 50, it is original that the pull bar 33 will return to its in the presence of the restoring force of elastic component 34 Position, so that plug-in strip 32 with the data processing module 60 there is contact 61 to make electrical contact with again.Therefore, it is above-mentioned in order to ensure Action can be smoothed out and laborsaving, the reply force direction of the elastic component 34 is overlapped with the direction of pull of the drag-line 50, But it is in opposite direction.In other words, as state elastic component 34 and drag-line 50 set point-blank.

The data processing module 60 includes a contact 61 that break-make is controlled by the plug-in strip 32, and a reception institute State the data processing unit 62 of the trigger signal of contact 61.The contact 61 can be a copper sheet, and it can be arranged on described In the material object of limit switch 30, then it is electrically connected with by wire with data processing unit 62.The specific setting side of the contact 61 Method should be easy to be expected by those skilled in the art, therefore only go out its structural representation in Fig. 2.The data processing unit 62 can be a programmable controller (PLC) or other data processing hardwares, such as be loaded with software program CPU Deng.The data processing unit 62 controls this layout machine 20 of institute between stopping and unlatching according to the trigger signal of the contact 61 Switching.It is assumed that when plug-in strip 32 is contacted with contact 61, the data processing unit 62 is according to making the trigger signal of the contact 61 Layout machine 20 is in opening, is contacted again after plug-in strip 32 departs from contact 61, and now data processing unit 62 is touched according to this The trigger signal of point 61 will shut down the layout machine 20.And contacted again after plug-in strip 32 departs from again with contact 61, it is described Data processing unit 62 can make the layout machine 20 start shooting according to the trigger signal of the contact 61 again, so as to go round and begin again so that Operative employee can only pull the drag-line 50 can be so that the layout machine 10 switches between unlatching and shutdown, and be in paving The optional position of cloth table 10 can, so as to avoid operative employee from being walked up and down by paving cloth table 10 30 meters to 50 meters long, and then It can avoid losing time and manpower, while can also be because of the work for avoiding initiation by layout machine 20 to be triggered without walking up and down Wound.As for the data processing unit 62, such as PLC, to those skilled in the art according to above-mentioned operation principle, its journey It is known that sequence, which is write, be will not be repeated here.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model The spirit of utility model and interior made any modifications, equivalent substitutions and improvements of principle etc., should be included in the utility model Protection domain within.
