Abstract

The utility model discloses a device for automatically detecting the thickness of a plate, and the device comprises two distance-measuring instruments, an alarm, and a PLC. The two distance-measuring instruments are fixed on an instrument-fixing piece, and a gap between the sensors of the distance-measuring instruments is reserved. The signal output ends of the distance-measuring instruments are respectively connected with the input end of the PLC, and the output end of the PLC is connected with the alarm. The PLC is used for calculating the thickness of the plate and comparing the calculation results with a technological reference value. The device achieves the instant measurement of the thickness of the plate on a product line. Meanwhile, the thickness of the plate can be calculated in real time through the PLC and the audible and visual alarm, and an unqualified plate, which exceeds the technological reference value, is found timely, thereby reducing the subsequent workload of sorting.

Description

A kind of sheet material automatic thickness checking apparatus

Technical field

The utility model relates to a kind of pick-up unit, especially a kind of panel thickness detection device.

Background technology

Plasterboard is as conventional building decorative plates, and the quality of its quality directly affects the euphorosia degree in finishing effect and finishing place.Whether the thickness of plasterboard meets technological requirement is to weigh the important indicator of plasterboard quality.Plasterboard was transported to after the second control stage after moulding, generally will pass through thickness measure, to find in time whether the product of producing meets technological standards.At present, employing be the method for manual measurement, be generally about per half an hour, to get a sample, with thicknessmeter (tolerance scope is 0-20*0.1mm), get point measurement.The method sample frequency is too low, pinpoint the problems not prompt enough, and measuring accuracy is inadequate, easily makes substandard product flow into next production routine.For head it off, a kind of automatic thickness checking apparatus that is arranged on the wide direction of motion of plate the utility model proposes.

Summary of the invention

The utility model provides a kind of sheet material automatic thickness checking apparatus, its objective is and solve in production process of plate, instant on-line thickness measurement is provided, find that in time thickness does not meet the defective sheet material of technological standards, avoid it to flow into lower one production routine, cause subsequent sort difficulty and increase subsequent sort workload.For achieving the above object, the technical scheme that the utility model is taked is as follows:

A kind of sheet material automatic thickness checking apparatus, comprise two stadimeters, alarm and PLC, two stadimeters are fixed on instrument fixture, between both sensors, be reserved with gap, the signal output part of stadimeter is all connected with PLC input end, the output terminal of PLC is connected with alarm, the computing that described PLC carries out thickness of slab calculating and result of calculation and technological standards value are compared.

Gap between the sensor of described two stadimeters is greater than the standard thickness of intending detecting sheet material.

Described instrument fixture is plane plate or support body.

Described stadimeter is ultrasonic range finder, infrared ambulator or laser range finder.

The utility model compared with prior art, has following beneficial effect:

First, the utility model, by stadimeter is fixed on production equipment, is realized thickness and is immediately completed on production line, simultaneously, can instant computing sheet metal thickness by PLC and audible-visual annunciator are set, and find to surpass in time the defective sheet material of technological standards, reduce subsequent sort workload.

Secondly, the utility model can be realized the instant inspection to each piece sheet material on production line, has overcome easily undetected problem of existing manual detection method, meanwhile, due to the employing of PLC, can greatly improve measurement progress, better controls the quality of production of sheet material.

Moreover, the advantage such as pick-up unit described in the utility model has simple in structure, easy to operate, and maintenance cost is cheap.

Accompanying drawing explanation

Fig. 1 is structure of the detecting device schematic diagram.

Reference numeral: 1-intends detecting stadimeter, 4-instrument fixture, 5-alarm, 6-PLC under sheet material, the upper stadimeter of 2-, 3-.

Embodiment

For the goal of the invention of thickness detection apparatus described in the utility model is better described, technical scheme and beneficial effect, now by reference to the accompanying drawings, be described further the utility model.

Fig. 1 is structure of the detecting device schematic diagram.Referring to Fig. 1, a kind of sheet material automatic thickness checking apparatus, the upper stadimeter 2 that comprises plan detection sheet material 1 top that is arranged on tangential movement, with the lower stadimeter 3 of intending detecting sheet material 1 below, being set to along plate width direction of upper stadimeter 2 and lower stadimeter 3, both sensors align up and down, between both sensors, be reserved with sheet separation, two stadimeters are fixed on instrument fixture 4, the signal output part of stadimeter is all connected with PLC6 input end, the output terminal of PLC6 is connected with alarm 5, the computing that described PLC carries out thickness of slab calculating and result of calculation and technological standards value are compared.

Blocked or stadimeter is miscued and affects measuring accuracy when preventing that gap from intend detecting sheet material 1 by stadimeter, the gap between the sensor of described two stadimeters is greater than the standard thickness of intending detecting sheet material.

In order to ensure accuracy of detection, upper stadimeter 2 and lower stadimeter 3 are fixed with instrument fixture 4 must be firm, even if the motion that when sheet material passes through detecting device in course of conveying is like this upper and lower slight fluctuations is advanced, because the distance between two stadimeters is constant, through the thickness of slab calculating, be also accurate.

Instrument fixture 4 is for being fixed on plane plate or the independent support body arranging on production equipment.Support body has connecting portion and support portion at least, no matter which kind of form, instrument fixture itself must be also fixed.

Referring to Fig. 1, in the present embodiment, stadimeter is chosen as infrared ambulator, and its measuring accuracy is higher, can meet accuracy of detection in gypsum board manufacture process, also can select according to demand the testing tool of other measuring distances such as ultrasonic range finder or laser range finder.

Principle of work: when sheet material is transported to the second control section by roller-way, upper stadimeter 2 in holding state and lower stadimeter 3 are measured the sensor of stadimeter 2 to the distance of intending detecting sheet material 1 upper surface simultaneously, the sensor of lower stadimeter 3 is to the distance of intending detecting sheet material 1 lower surface, the electric signal transmission that stadimeter changes into 4-20 milliampere signal by data is to PLC, the computing that PLC calculates through thickness of slab and result of calculation and technological standards value are compared, within the monitoring point of sheet metal thickness surpasses PLC during preset value, be judged as and exceed technic index, PLC is transferred to alarm 5 by signal, alarm 5 is reported to the police.Alarm 5 can be selected conventional audible-visual annunciator.

The technical solution of the utility model not only can detect for thickness in gypsum board manufacture process, and also can be used for other sheet materials has the detection of controlling the product requiring compared with precision as composite board etc. and other to thickness.

Although the embodiment that the utility model discloses as above, the embodiment that its content just adopts for the ease of understanding the technical solution of the utility model, is not intended to limit the utility model.Technician under any the utility model in technical field; do not departing under the prerequisite of the core technology scheme that the utility model discloses; can in the form of implementing and details, make any modification and variation; but the protection domain that the utility model limits, the scope that still must limit with appending claims is as the criterion.
