Plate 4, the top of postive stop baffle 4 is corresponding with two cart sensors 5, and the length of postive stop baffle 4 and the length of working region are identical；
Width of the six trolley sensors 3 along working region is uniformly distributed；
Cart 2, trolley 1 and the sensor passes through control line respectively and connect with PLC.
Further, the sensor is the close switch of LJC18A3-B-Z/BX NPN.
Further, the PLC is Mitsubishi PLC.
Further, the postive stop baffle 4 is metal plate, is horizontally mounted.
Further, two cart sensors 5 are separately mounted on two trolley tracks on cart 2；Two
The line of cart sensor 5 and the longitudinal centre line of postive stop baffle 4 are on the same vertical plane.
Further, six trolley sensors 3 are mounted on a trolley track on cart 2；Six trolleies
The line of sensor 3 is straight line.
Further, the PLC is also connect with host computer and security module respectively；The PLC controls single through cart
Member, cart contactor are connect with cart operation motor, and the PLC is through trolley control unit, trolley contactor and trolley travelling
Motor connection.
The working principle of the utility model is: installing cart sensor 5 and trolley sensor 3 additional respectively on cart 2, pass through
Feedback signal identifies hanging object and surface structures, and there may be the regions of interference, i.e. press machine working region, when purlin vehicle is run herein
When region, sensor detects the signal that postive stop baffle 4 is fed back, so that purlin vehicle be made to brake, avoids collision accident.The utility model
The generation of safety accident can be avoided under the premise of guaranteeing that purlin vehicle operates normally function.
The utility model the specific operation is as follows:
Confirm as shown in Figure 1, the running position of trolley 1 can be detected by trolley sensor 3, the position of cart 2 is divided into two
A part, safety zone and danger zone, i.e., (safety zone, region 1, region 2 and region 3) and limit except postive stop baffle 4
Within baffle 4 (danger zone or working region), the working region of entire press machine is danger zone, and the utility model needs to complete
Following function: at safety zone, cart 2 and trolley 1 can arbitrarily be run purlin vehicle；Purlin vehicle is when danger zone works, trolley 1
It can only be run in the two side areas (region 1 and region 3) of press machine, after completing lifting operation, cart 2 sails out of danger zone, purlin
Vehicle can free-running operation.
Described respectively from 4 directions of the operation of purlin vehicle below working principle of the utility model is:
1, purlin vehicle is run from mold storing region to press machine working region (the purlin position Che Congtu1 is run to the right).It is such as small
Vehicle 1 is between the first to the 6th trolley sensor 3 and (sequentially presses Fig. 1 sequential organization from front to back), 2 not running of cart to limit
At 4 left end of baffle, then trolley 1 and cart 2 can be with free-running operations；If cart 2 is run at postive stop baffle 4, until its left end,
Cart sensor 5 detects the signal of postive stop baffle 4, then cart 2 is braked immediately, may only be to reverse direction operation, or stops,
Meanwhile trolley 1 can be along track free-running operation, until trolley 1 leaves danger zone, i.e., the inspection of the first to the 6th trolley sensor 3
1 signal of trolley is not detected, at this point, cart 2 can be with free-running operation.
2, purlin vehicle is in region 1.In this region, cart sensor 5 is able to detect that the signal of postive stop baffle 4 always, herein
Under the premise of Chief Signal Boatswain is logical, trolley 1 is run in a limited space (region 1), if trolley 1 is run to press machine working region, the
One trolley sensor 3 detects 1 signal of trolley, at this point, trolley 1 is out of service, or to reverse direction operation, until far from press machine
Working region, cart 2 and trolley 1 can operate normally, and when cart 2 leaves 4 region of postive stop baffle, trolley 1 can arbitrarily be run (no
It is limited by the first trolley sensor 3).
3, purlin vehicle is travelled from region 2 to press machine working region.This process is similar with first traffic direction situation, only
Traffic direction is opposite.To avoid trolley 1 and press machine from colliding, when trolley 1 is between the first to the 6th trolley sensor 3,
Cart 2 is travelled to press machine region, and cart sensor 5 detects 4 right end signal of postive stop baffle, and cart 2 stops at this time, or to
Opposite direction movement.When trolley 1 leaves the first to the 6th trolley 3 region of sensor, cart 2 can be with free-running operation.
4, purlin vehicle is in region 3.In this region, situation is similar in region 1.The Chief Signal Boatswain of postive stop baffle 4 is logical, 1 energy of trolley
Enough operations in the confined space (region 3), if trolley 1 is run to press machine working region, the 6th trolley sensor 3 can issue letter
Number, make the stopping of trolley 1 or inverted running, when trolley 1 sails out of danger zone, the 6th trolley sensor 3 loses signal, this
When, purlin vehicle operates normally.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, installation can be changed at any time according to the operation characteristic of distinct device and safety zone.
