End and outfan, described input is connected with vision sensor A 13 and vision sensor B 14,
Described outfan connects jerk circuit and band-type brake circuit, because in the middle of traditional mill,
There is certain potential safety hazard when of use, normally opened contact controls mill band-type brake action, often
Closed contact control mill scram action, when contact is damaged, safety device cannot effective action,
Safe class is relatively low, one can not be provided ultra-safe to execute to workmen when in use
Work environment, in the present embodiment, by adding jerk band-type brake circuit and skirt emergency stop switch,
Can be controlled by the moment human response of skirt emergency stop switch when of use use
The shutdown of mill, and be provided with trigger point at jerk foot switch 8 and be connected to limit switch
A 10, is provided with safety push-rod 11, sets after described safety push-rod 11 at the middle part of described preliminary roller 3
Limit switches B, can make limit switch moment react, institute when foot switch action when
So that the present embodiment provide not only switch detection and the arresting gear the most automatically of human response.
It should be noted that above described mill 1, position, both sides is provided with vision sensor A 13
With vision sensor B 14, said two sensor all faces preliminary roller and back roller junction 16,
Vision sensor detection sizing material crush-zone, enters detection zone when there being the object differing from sizing material color
In territory, meeting stopping alarm at once, ensure the safety of employee to greatest extent.
Additionally, ladder diagram as shown in Figure 2, described safety pin 7, limit switch A 10,
Limit switch B 12, safe pull rope 15 are provided with two secondary normally-closed contacts and two secondary normally opened contacts,
One pair of wherein a secondary normally-closed contact and the limit switch B 12 of described limit switch A 10 is normally closed
Contact series also accesses on safety relay A, another secondary normally closed point of limit switch A 10 with
Another secondary normally-closed contact series connection of limit switch B 12 is linked in safety relay A, described
A safety pin 7 wherein secondary normally-closed contact is connected with a pair normally-closed contact of safe pull rope access
In safety relay B, another secondary normally-closed contact of described safety pin is another with safe pull rope
One secondary normally-closed contact series connection is linked in safety relay B, described safety relay A and safety
Relay B is concatenated in the middle of jerk loop, when limit switch A 10 and limit switch B 12
In any one normally-closed contact become the when of normally opened contact that safety relay A will
Trigger so that the normally opened contact of safety relay A becomes normally closed, the most also allow for jerk electricity
Road works, and mill 1 is shut down.
Described on base, as shown in the ladder diagram of Fig. 2, described safe pull rope 15, safety are inserted
Pin 7, limit switch A 10, a wherein secondary normally opened contact of limit switch B 12 connect formation
Brake loop A, another secondary normally opened contact forms band-type brake circuit B after being connected, as shown in Figure 2,
Normally opened contact therein is for being connected in parallel, when one of them normally opened electric shock becomes normally closed when,
The brake loop of its correspondence is also switched on, and the driving means of mill is carried out by described brake loop
Band-type brake, mill is shut down.It is recognised that in the present embodiment, when safety pin 7, spacing
Switch A 10, limit switch B 12, any position of safe pull rope 15 occur the most abnormal
Time, jerk circuit and brake loop will be touched, also it is ensured that mill is extremely short simultaneously
Time stop, promote safe class, it is ensured that the construction environment of a safety.
Above-described is only the preferred embodiment of the present invention, it is noted that for this area
Those of ordinary skill for, without departing from the concept of the premise of the invention, it is also possible to do
Going out some deformation and improvement, these broadly fall into protection scope of the present invention.
