A lifting mechanism jacks up the upper edge of a continuous operated conveyer belt and an operated glass on a main roller-way and rapidly sends out the glass with the angle of 90 DEG along the operation direction of the main roller-way. Then the lifting mechanism resets, the upper edge of the conveyer belt falls down, and the rear glass can continue to run forward on the main roller-way. The utility model has the advantages of high efficiency, simple structure, convenient maintenance, low cost, good quality and safety.

Description

The utility model has been introduced a kind of glass or other burst conveyer frangible, the rapid wear thin plate.

The speed that glass after cutting on the floatation glass production line is carried on master roller is very fast, for adapting to the needs of stacking, vanning operation, glass must be told some branch lines and carry, and is called " glass slice ".

At present domestic five floatation glass production lines, all the employing artificial burst on air table of having.When producing the glass of 5 millimeters thick, if every specification that is cut into 2 meters * 1.5 meters is carried, its running velocity is 429 meters/hour.Before and after cycle of run between adjacent two sheet glass be 16.8 seconds, artificial burst.When producing the glass of 2 millimeters thick, if every specification that is cut into 1.2 meters * 1.5 meters is carried, its running velocity is 1000 meters/hour.Before and after between adjacent two sheet glass cycle of run only have 4.3 seconds.If preceding sheet glass is parked in the burst station, back sheet glass moves on, and only needs 2.42 seconds two sheet glass just to collide from beginning to end, knocks into the back.So the work point sheet of choosing is difficult to accomplish.Moreover manual burst labor strength is too big.Glass with 2 meters of 5 millimeters thick * 1.5 meters specifications calculates, and per tour needs 16 people, 48 people of class Three on the burst station, add 6 people in addition and take over other's shift, amount to staffing 54 people, everyone per tour will divide 200 sheet glass, every is heavy 37.5 kilograms, thus per tour everyone need carry the glass of 7.5 tons of weights.When producing structural glass, a dead lift, the breakage rate height often goes out accident on duty.Produce the above glass of 8 millimeters thick, every weight is too big, and artificial burst can not realize that also easily deposit foreign matter in the felt on the air table in addition, during a dead lift, glass slides and just is scratched on felt.So artificial burst labour intensity is big, efficient is low, and is dangerous, easily scratches glass, reduces product design, can not satisfy 2 millimeters thin glass and the needs of heavy sheet glass production more than 8 millimeters.

From the foreign patent document of having retrieved (referring to the list of references of this paper back), learn, the glass slice conveyer is to adopt some groups of rubber tires or some belts and driving system thereof are housed on a platform in the American-European countries, these rubber tires or belt are to intert to be installed between the master roller of glass run, and are lower than master roller.When glass arrives the burst station, master roller on the burst station is out of service, by the pneumatic or hydraulic gear of a cover platform that some groups of rubber tires or some belts are installed is risen then, and glass jack-up from the master roller, restart rubber tire or belt glass along sending at an angle of 90 with the master roller service direction.Adopt this method to carry out glass slice, its delivery speed is slower, and per minute one sheet glass needed for 10 seconds, therefore, can only divide big sheet glass, can not divide medium and small sheet glass.In addition, because platform weight is big, so lifting action is realized by pneumatic or hydraulic gear.Auxiliary facilities is many like this, as oil pump, Air compressor, various valve and control element etc., to making the wafer breaker complex structure, needs more high-quality service worker and could guarantee ordinary production.And make difficulty, cost an arm and a leg every about 200,000 dollars.

The purpose of this utility model be with intert be installed in propulsion source between the master roller and driver element not need with the belt conveyor system of the continuous operation of belt conveyor lifting with by infrared electro reflection detection head sender, electromagnet is a propulsion source, pass through lever principle, the lifting mechanism combination that is risen and fallen in the top of belt conveyor, form the glass slice conveyer, in order to adapt to the needs of producing all thickness all size glass slice, the workman is freed from heavy manual labor.Thereby a kind of efficient height, glass slice conveyer that quality is good, simple in structure, easy to maintenance, cheap, safe and reliable are provided.

Now that structure of the present utility model and operation program is as follows by schematic view illustrating.

Fig. 1 be glass slice conveyer jack-up and when carrying glass at the motion scheme drawing of vertical.

Fig. 2 is a glass slice conveyer belt conveyor installation site scheme drawing in the horizontal direction.

Fig. 3 is that glass slice conveyer lifting mechanism axle is surveyed scheme drawing.

On floatation glass production line, when the glass (7) on the master roller (11) runs to the burst station, infrared electro reflection detection head (6) sends signal immediately and gives electromagnet (14), make its adhesive upwards, drive lever (13), connecting lever (10) shakes (see figure 1), thereby makes alighting gear (9) and the some groups of belt holders (8) that intert between master roller are risen, and the height and position of belt holder (8) can be by vertical nut (12) adjusting (see figure 3).The main motion process drive belt (2) of dc speed-regulating motor (1) and chain (3) double reduction make belt pulley (4) rotation (see figure 1) and drive belt conveyor (5) (see figure 2) of interting between master roller and move continuously, its sense of motion and master roller (11) throughput direction at an angle of 90, the degree of tension of belt conveyor can be regulated (see figure 1) by lateral adjustments screw rod (15).Utilize the resilient characteristics of belt conveyor, when lifting mechanism rises, some groups of belt holders (8) can form a plane that is higher than master roller (11) to the top jack-up of some groups of belt conveyors (5), and with the steady jack-up disengaging of glass (7) master roller (11), because belt conveyor (5) is operation continuously, so glass (7) is sent fast 1～1.5 second moment by jack-up the time, branches away from master roller (11).Even it is fast that the glass of 2 millimeters thick is gone up running velocity at master roller (11), also can guarantee not occur the phenomenon that knocks into the back.After glass (7) breaks away from the burst station, infrared electro reflection detection head (6) sends signal for electromagnet (14), lifting mechanism is resetted, the top of the belt conveyor (5) of operation falls and is lower than master roller (11) continuously, does not need on the master roller (11) can move forward at the glass of this station burst.

The advantage of this utility model and good effect:

1, the power source of elevating mechanism is electromagnet. Because the power source of belt conveyor system and actuated element do not need and simultaneously lifting of belt conveyor in this glass sheet conveyer, only be that elevating mechanism is the top jack-up of belt conveyor and hold up glass and get final product. The weight of elevating mechanism and every sheet glass is little, and the stroke that rises and falls is again little, so electromagnet is that power can be satisfied the demand fully. So just replaced complicated pneumatic, hydraulic mechanism, overcome owing to shortcoming pneumatic, the malfunctioning misoperation that brings of hydraulic system element. Simple in structure, easy to maintenance, safe and reliable, energy savings, cheap advantage are arranged.

Just send fast when 2, the belt conveyor that moved continuously of the glass that moves on the master roller holds up,, can satisfy the needs of the middle fritter glass slice of 2 millimeters thin glass of production and all thickness than fast 7～10 times of the glass slice device speed of some American-European countries.

Best implementation condition of the present utility model is: at the bottom of when the top of belt conveyor falls in 5～6 millimeters of master rollers; Be higher than 5～6 millimeters of master rollers during jack-up; Belt conveyor speed 1～2 meter per second; Aluminium alloy extrusions is adopted in alighting gear and belt holder; Belt conveyor is with top smooth V-belt.The common mechanical manufacturing process that is embodied as of the present utility model, accuracy requirement is not high, does not have special processing and packaging technology, and factory has made model machine, through more than 300 test runs, has reached to give and has decided effect.Be about to be installed on the manufacturing line and use.
