Abstract
The utility model discloses a protection device for flying saw control system, the device includes motion control ware, multi-functional timer and relay coil, and motion control ware connects the start contact of multi-functional timer, and the setting is normally opened to two time limit contacts of multi-functional timer, and the contact closure then establishes ties relay coil two time limit, relay coil and the production line unit electrical linkage of welded tube. Utilize the utility model discloses a device flies saw control system can not receive the interference again and can in time protect and fly the saw, and then can protect whole production line. When the motion controller is abnormal and cannot provide the pulse signal with the fixed period, the multifunctional timer enables the starting point of the relay to be closed, the machine set of the chain production line is shut down in time, and serious mechanical damage is avoided, so that the safe and efficient production of the production line is guaranteed. The utility model discloses the device structure is succinct reasonable, design benefit, and the practicality is strong.
Description
Technical Field
The utility model belongs to the technical field of automatic control, in particular to detection and protection device when flying saw control system is unusual.
Background
With the increasing strong demand of the straight welded pipe products with larger caliber, the application of the flying saw which is responsible for cutting the straight welded pipe in a fixed length mode on a production line is increased year by year.
The flying saw is a fixed-length cutting device in a straight welded pipe production line, and due to the fact that various high-power electrical devices exist on a unit of the welded pipe production line, a flying saw control system is easily interfered to cause abnormity, and if the flying saw cannot be protected in time, the flying saw is seriously damaged, and the efficiency of the whole production line is also influenced.
At present, most flying saws are not provided with a detection and protection device when a control system is abnormal.
Disclosure of Invention
To the problem that exists among the above-mentioned prior art, the utility model provides a to flying the detection protection device when saw control system is unusual, can protect flying the saw, the security is strong.
The technical scheme of the utility model as follows:
the utility model provides a protection device for flying saw control system, the device includes motion control ware, multi-functional timer and relay coil, and the start contact of multi-functional timer is connected to motion control ware, and the setting is normally opened to the time limit contact of multi-functional timer, and the relay coil is established ties to the time limit contact, relay coil and welded tube production line unit electrical interlocking.
Furthermore, the motion controller is electrically connected with a saw vehicle motor driving device of the flying saw control system to control the operation of the flying saw.
Further, the multifunctional timer is powered by a 24V direct current power supply.
A flying saw control system comprises the protection device and a sawing machine motor driving device of the flying saw.
The utility model has the advantages as follows:
utilize the utility model discloses a device can in time protect the fly saw when fly saw control system receives the interference and appears unusually, and then can protect whole welded tube production line.
When the motion controller is interfered to be abnormal and the pulse signal with the fixed period can not be provided, the multifunctional timer enables the opening point of the relay to be closed, the machine set of the chain production line is stopped in time, and serious mechanical damage is avoided, so that the safe and efficient production of the welded pipe production line is ensured.
The device of the utility model has the advantages of simple and reasonable structure, ingenious design and strong practicability.
Drawings
Fig. 1 is a schematic circuit diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, the protection device for a flying saw control system of the present invention comprises a motion controller 1, a multifunctional timer 2 and a common relay 3; the motion controller 1 outputs a pulse signal with a fixed period, the pulse signal is connected with a starting contact B1 of the multifunctional timer 2, time-limited contacts NO (normally open) 15 and NO 18 of the multifunctional timer 2 are connected with coils of the relay 3 in series, and the starting point of the relay 3 is electrically interlocked with a production line unit of a welded pipe.
The motion controller 1 in the present embodiment is a CT-III motion controller of shenyang kat electromechanical devices ltd, which is directly available on the market; the motion controller 1 may be a controller from other manufacturers, such as those from siemens.
The multifunctional timer 2 is an H3DK-M1 multifunctional timer purchased from Onglong. The multifunctional timer 2 needs 24V dc power supply.
The motion controller 1 is also in communication connection with the flying saw to control the operation of the flying saw. Specifically, the motion controller 1 is electrically connected to other units of the flying saw control system (such as a saw car motor driving device of the flying saw), so as to control the operation of the flying saw.
The utility model discloses a protection device for flying saw control system carries out the protection process as follows:
the motion controller 1 is responsible for the reciprocating motion control of the flying saw, and simultaneously outputs a pulse signal with a fixed period to be connected with a starting contact B1 of the multifunctional timer 2, time- limited contacts 15 and 18 of the multifunctional timer 2 are connected into a coil of the relay 3 in series, and the starting point of the relay 3 is electrically interlocked with a production line unit of a welded pipe.
When the motion controller 1 is abnormal and cannot provide the pulse signal with the fixed period, the multifunctional timer 2 enables the opening point of the relay 3 to be closed (the time- limited contacts 15 and 18 of the multifunctional timer 2 are closed, and the relay 3 connected in series is also closed), and the chain welded pipe production line unit is stopped in time, so that serious mechanical damage is avoided, and the safe and efficient production of the production line is ensured.
The multifunctional timer 2 can be alternatively realized by a programmable logic controller PLC, etc., but the scheme of the multifunctional timer 2 of the embodiment is simple and convenient, and has low cost.
The above description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
