Existing taking-up equipment running:
1, mandrel expands, and drive motors rotates, and finds the jaw position of bite strap steel head;
2, take the lead the laggard jaw position of threading, jaw is closed;
3, cycling start, mandrel keep swelling state always;
4, produce and finish, mandrel shrinks, and core of steel coil and mandrel are broken away from;
5, coil stripping car is transported coil of strip from mandrel.
The shortcoming that existing taking-up equipment exists:
Mandrel expands to detect just and carrys out indirect detection by detecting hydraulic system pressure, has uncertain factor, can not accurately reflect the virtual condition of mandrel, if mandrel shrinks in process of production, pressure does not but have anything to change, and thinks that mandrel is in swelling state, will cause unloading the problem of volume.

As the further restriction to the technical program, described mandrel harmomegathus automatic detection device comprises detecting signal unit and the sense switch that is mated, described sense switch connects remote I/O station, described remote I/O station connects the PLC controller, described detecting signal unit is arranged on and describedly batches mandrel body rear side and with described, batch mandrel body rotation, described sense switch is arranged on described gearbox rear side, makes described detecting signal unit just in time be positioned at described sense switch top when batching this volume expansion of mandrel.
As the further restriction to the technical program, described detecting signal unit is the irony block.
As the further restriction to the technical program, described sense switch is static position switch (7).
As the further restriction to the technical program, described sense switch is that optoelectronic block is closed.
As the further restriction to the technical program, described signal detection block is the laser reflection eyeglass.
Compared with prior art, advantage of the present utility model and good effect are: the utility model is realized mandrel harmomegathus realtime monitoring by mandrel harmomegathus automatic detection device, in case the sign that shrinks appears in mandrel in coiling process, can in time find and make system shutdown, having avoided in the coiling process because mandrel has shunk the problem that causes unloading volume.
Description of drawings
Fig. 1 is the structural representation of existing taking-up equipment.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is further described in detail.
Referring to Fig. 2, the utility model comprises drive motors 1, mandrel harmomegathus hydraulic means 2, gearbox 3, batches mandrel body 4, base 5, sense switch 6, detecting signal unit 7, remote I/O station 8, PLC controller 9 and Pressure gauge 10, and described mandrel body 4 rear sides that batch are provided with mandrel harmomegathus automatic detection device.
Described mandrel harmomegathus automatic detection device comprises detecting signal unit 7 and the sense switch 6 that is mated, described sense switch 6 connects remote I/O station 8, described remote I/O station 8 connects PLC controller 9, described detecting signal unit 7 is arranged on and describedly batches mandrel body 4 rear sides and with described, batch mandrel body 4 rotation, described sense switch 6 is arranged on described gearbox 3 rear sides, when batching when mandrel body 4 expands, makes described detecting signal unit 7 just in time be positioned at described sense switch 6 tops.
