According to the invention, when the glass reaches the previous blocking roller area of the stacking area, the blocking rollers block the glass, then the glass reaches the stacker area, the stacker is effective in measuring the position of the wide photoelectric scanning glass, then the wide photoelectric scanning glass is grabbed, the glass is guaranteed to be normally placed on a box position, the glass is packaged orderly, and the transportation is convenient.

Description

Roller way blocking roller device of glass production line and control method thereof

Technical Field

The invention relates to the technical field related to roller bed devices, in particular to a roller bed blocking roller device of a glass production line.

Background

At present, in the production line conveying of glass, roller ways are mostly adopted for conveying, and finally, the designated box position is placed on glass through a stacking machine, but the conveying roller way distance of the 800T/D glass production line is long, in the conveying process, due to the abrasion of rubber wheels of the roller ways and the deformation of the roller ways, the deviation phenomenon can exist when the glass is conveyed, the deviation is serious when the glass is conveyed to the stacking machine, the wide photoelectric worker cannot find the glass edge when the stacking machine detects the width, the glass cannot be grabbed when reaching the stacking machine frequently, the system alarms and stops, the glass cannot be normally stacked on the box position, the packing rate and the safety of products are influenced, and the direct economic loss is brought to production.

Therefore, a transportation device for ensuring that the glass reaches the stacker area and meets the requirement of photoelectric scanning is needed, which is a technical problem to be solved urgently by those skilled in the art.

Disclosure of Invention

In order to solve the technical problem, the invention provides a roller way blocking roller device of a glass production line and a control method thereof

The invention provides a roller way blocking roller device of a glass production line and a control method thereof, which are used together with a stacker of the glass production line.

The further scheme is as follows: the blocking roller is connected with the air cylinder through an electromagnetic valve.

The further scheme is as follows: also comprises a PLC control device.

The further scheme is as follows: the roller way is a 13M13 roller way.

The further scheme is as follows: the control method of the device comprises the following steps:

step 1: two photoelectric switches are arranged on the conveying roller way;

step 2: the photoelectric switch outputs a signal after sensing the glass;

and step 3: the program block receives a signal output by the photoelectric signal;

and 4, step 4: the program block is connected with the touch screen variable, and comprises the setting of the free stop roller of the touch screen, the setting of the stop time of the free stop roller of the touch screen and the setting of the deceleration time of the free stop roller of the touch screen;

and 5: starting a free stop roller delay deceleration time timer T1;

step 6: the free stop roller can be closed and outputs a switch signal to make the free stop roller fall down;

and 7: starting a free deceleration time timer T2;

and 8: stopping the roller way time delayer T3, and stopping the roller way;

and step 9: after the time delay is finished, the roller way motor and the free stop roller reset, the conveying roller way rotates, and the free stop roller is lifted.

Compared with the related art, the invention has the following beneficial effects: by the invention, the glass reaches the previous area of the stacking area, the stop rollers stop the glass in order when the stop rollers reach the area, then the glass reaches the stacker area, the stacker width-measuring photoelectric switch scans the effective position of the glass, and then the glass is grabbed, so that the glass is normally placed on a box position, the glass is packaged in order, and the transportation is convenient.

Detailed Description

The invention will be further explained with reference to the drawings and the embodiments.

Example 1

As shown in fig. 1, the invention provides a roller way blocking roller device of a glass production line, which is used in cooperation with a stacker of the glass production line and comprises a roller way, a roller and a blocking roller device, wherein the roller way is a 13M13 roller way, the blocking roller device comprises a photoelectric switch and a blocking roller, the photoelectric switch is arranged in front of the blocking roller, the blocking roller and the photoelectric switch are arranged on the same section of roller way, and the blocking roller is connected with an air cylinder through an electromagnetic valve; the invention also comprises a PLC control device. As shown in fig. 2 and 3, when the glass reaches a preset position, the photoelectric switch signal is turned on, the PLC receives the signal and starts delaying for 5 seconds, in the 5 seconds, the roller way conveys the glass to the stop roller position, a switching value signal is output to control the electromagnetic valve to execute the cylinder, so that the stop roller falls down, the delayer delays for 2 seconds after falling down and suspends the roller way, the stop roller contacts with the glass within the two seconds and continuously rolls forwards through the roller way, so that the stop roller can be ensured to stop the glass, at this time, the stop roller is freely lifted, the conveying roller way is started, and a work task is completed.

Example 2

On the basis of embodiment 1, the two blocking rollers of this embodiment are respectively arranged on two sides of the blocking roller, and the two blocking rollers are located on the same horizontal line, as shown in fig. 2 and fig. 3, when the glass reaches a predetermined position, a photoelectric switch signal is turned off, the PLC receives the signal and starts delaying for 10 seconds, in the 10 seconds, the roller way conveys the glass to the blocking roller position, a switching value signal is output to control the electromagnetic valve to execute the cylinder, the blocking roller falls down, the delayer delays for 5 seconds after the falling down and suspends the roller way, the blocking roller contacts with the glass within the 5 seconds, the blocking roller continues to roll forwards through the roller way, the blocking roller can be guaranteed to block the glass, at this time, the free blocking roller is lifted, the roller conveying way is started, a work task is completed, and the work is performed once when each piece of glass comes in.

According to the invention, when the glass reaches the front roller blocking area of the stacking area, the rollers block the glass evenly, then the glass reaches the stacker area, the stacker is effective in measuring the position of the wide photoelectric scanning glass, then the glass is grabbed, the glass is guaranteed to be normally placed on a box position, the glass is packaged neatly, and the transportation is convenient.
