Description

The automatic shear of section bar tinuous production

Technical field

The utility model relates to the automatic shear of a kind of section bar tinuous production.

Background technology

The energy-conservation plate of polyurethane is a kind of novel building energy-conserving plate material that is widely used in fields such as building inside and outside wall, air conditioner ventilating system and thermal insulating door thermally insulated door, and it is the profile plate that two-layered steel plates is bonded to one after by curing molding with polyurethane foams between the upper and lower two-layered steel plates.The tinuous production of this section bar sets gradually uncoiler according to the section bar processing process, the steel plate shearing machine, beading machine, make-up machine, rollgang, preheating apparatus, foamed cell, feed rods device (on lower floor's steel plate, evenly spraying the equipment of chemical raw material), two crawler belt equipment (equipment of chemical raw material high-pressure foam and curing molding in two crawler belts), process equipments such as cast-cutting saw and piling turning device, see Fig. 1, the shear of this production line comprises steel plate shearing machine before the steel plate forming and the cast-cutting saw after the moulding, cast-cutting saw is with through overmolding, product after the foaming requires to be cut into pieces according to the finished product length dimension, the steel plate shearing machine then is when a coil plate is about to use up the steel plate tailing of not enough fixed length to be cut off or when a collection of production closes to an end remaining steel plate cut off, and causes waste in order to avoid unnecessary steel plate enters road, back production process.At present, steel plate shearing machine on this tinuous production and other equipment are without any related, when the steel plate shearing machine starts the execution shearing is by manually operated, common way is according to the cut lengths of steel plate or when a coil plate is about to use up the remaining length of this coil plate and the cutter distance to cast-cutting saw to be compared, the artificial shear signal that sends, start cutter by operating personnel then and carry out shearing, the mode that this control is sheared is not easy to execute-in-place for the production line of hundred meters left and right sides length, and it is bigger to cut off error, and error is usually all more than 1 meter.

The utility model content

The purpose of this utility model provides a kind of automatic shear of section bar tinuous production that can cut off steel plate before moulding according to the steel plate preseting length automatically.

For achieving the above object, the utility model adopts following technical scheme: the automatic shear of section bar tinuous production, comprise the two crawler belt motors on the production line and be positioned at before shear steel plate shearing machine on the station and the cast-cutting saw on the cutting work station of back, be coaxially connected with rotary encoder on the blower fan output shaft of two crawler belt motors, on the pressuring flat device lower position of cast-cutting saw sensor is installed, sensor is electrically connected with a Programmable Logic Controller by holding wire, also is connected with the text display that is used to import the steel plate preseting length on the Programmable Logic Controller; Sensor provides enabling signal to Programmable Logic Controller, and rotary encoder provides steel plate walking length pulse signal to Programmable Logic Controller, and the control output control steel plate shearing machine of Programmable Logic Controller is carried out shear action.

Described rotary encoder is installed on the blower fan output shaft of two crawler belt motors by shaft coupling.

The utility model in the course of the work, by text display input steel plate preseting length, provide steel plate walking length pulse signal by rotary encoder to Programmable Logic Controller, after Programmable Logic Controller receives sensor signal, start zero clearing and begin meter length, when steel plate walking length equals the steel plate preseting length, Programmable Logic Controller sends to the steel plate shearing machine and shears instruction, control steel plate shearing machine is carried out shear action, in time cut off the steel plate on the tinuous production, thereby avoid unnecessary steel plate to enter operations such as follow-up beading, moulding, cut the waste.The speed of travel (being the operating rate of whole production line) owing to steel plate on the production line is synchronous with the speed maintenance of two crawler belt motors; rotary encoder output shaft and two coaxial connection of crawler belt motor output shaft; guaranteed the physical length strict conformance that umber of pulse that rotary encoder is gathered and steel plate are walked; realized that accurate meter is long; the material overtaking wave takes minimum when having guaranteed shutdown; also guaranteed simultaneously in continuous flow procedure, the steel plate mating interface to be controlled on the needed position; reduce waste product, improved product percent of pass.

The specific embodiment

Fig. 2-automatic the shear of section bar tinuous production shown in Figure 3, comprise two crawler belt motors of being positioned on the production line on the polyurethane foam station and be positioned at before shear steel plate shearing machine on the station and the cast-cutting saw on the cutting work station of back, be coaxially connected with rotary encoder 3 by shaft coupling 2 on the blower fan output shaft of two crawler belt motors 1.On the pressuring flat device lower position of cast-cutting saw sensor is installed, sensor is electrically connected with a Programmable Logic Controller by holding wire, and Programmable Logic Controller is electrically connected with rotary encoder by another holding wire, also is connected with text display on the Programmable Logic Controller; Sensor provides zero clearing and count enable signal to Programmable Logic Controller, and rotary encoder provides steel plate walking length pulse signal to Programmable Logic Controller, and the control output control steel plate shearing machine of Programmable Logic Controller is carried out shear action.Above-mentioned text display is mainly used in input steel plate preseting length and shows steel plate walking length.

During work, start cast-cutting saw, the cast-cutting saw head descends, after the cast-cutting saw pressuring flat device flattened and to put in place, it is long that the sensor-triggered Programmable Logic Controller begins meter, when the length of walking when steel plate equals preseting length, Programmable Logic Controller sends shear signal, and control steel plate shearing machine is carried out shear action.

In the production scene, the steel plate shearing machine has more than 80 meter to cast-cutting saw, and length that input slab will cut among the cast-cutting saw PC and piece number are by text display input steel plate preseting length.Among Fig. 1, each station represented in letter, the line of band arrow is represented the steel plate on the production line, if length X J is the integral multiple of sheet material cut lengths, X is moving point, and XB is exactly the setting value of steel plate shearing length so, with this numerical value input text display, when the rotary encoder measured lengths equals XB (X overlaps fully with the B point), to give an order by Programmable Logic Controller, notice steel plate shearing machine is carried out and is sheared.
