Technical Field
[0001] The utility model relates to the technical field of measuring equipment, in particular to a device for detecting the center height of a material roll. Background Art
[0002] The coil is loaded into the unwinding mechanism through the lifting loading device. When loading, the lifting loading device transports the coil to the designated loading station. After the position of the coil is determined, the lifting loading device lifts the coil. When the insertion holes at both ends of the coil are aligned with the cone tops at both ends of the unwinding mechanism, the lifting stops. Finally, the cone tops are inserted into both ends of the coil to complete the loading action. At present, the lifting height of the coil is manually determined, which not only has poor accuracy, but also cannot realize automatic loading. Summary of the invention
[0003] The technical problem to be solved by the utility model is to provide a material roll center height detection device, which can accurately detect the center height of the material roll and facilitate automatic material loading.

The principle of the utility model: when loading, the lifting and feeding device lifts the material roll at the loading station, before the center of the material roll coincides with the center of the cone top, the beam switches on the two cone tops cannot complete the matching, only when the beam switches on the two cone tops complete the matching, the beam switch gives a trigger signal to control the lifting and feeding device to stop lifting, and finally the two cone tops extend out and clamp at the two ends of the material roll.
[0005] As an improvement, one cone top is provided with four circumferentially evenly distributed counter-beam switch transmitters, and another cone top is provided with a circle of closely arranged counter-beam switch receivers. The four counter-beam switch transmitters can be paired with four counter-beam switch receivers at the same time.
[0006] As an improvement, five anti-beam switch transmitters are provided on one cone top, four of which are evenly distributed on the circumference, and another anti-beam switch transmitter is located in the middle position of the cone top; another cone top is provided with a circle of anti-beam switch receivers arranged closely and in the middle position, and the five anti-beam switch transmitters can be paired with five anti-beam switch receivers at the same time.
[0007] As an improvement, the transmitting switch transmitter is arranged on the top of the cone with rotational power.
[0008] Compared with the prior art, the utility model has the following beneficial effects:
[0009] The transmitter and receiver of the through-beam switch are matched to detect whether the center of the material roll is aligned with the center of the cone top, so as to achieve precise control and judgment, and help to realize automatic loading. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 Schematic diagram of the detection device detecting the center of the coil. DETAILED DESCRIPTION
[0012] The utility model will be further described below in conjunction with the accompanying drawings.
[0013] like Figure 1 , 2 As shown, a device for detecting the center height of a material roll includes a reeling mechanism 2 and a detection mechanism. The reeling mechanism 2 includes two cone tops arranged at both ends of the material roll, one of which is a passive cone top 22 connected to a cylinder, and the other cone top is an active cone top 21 connected to a transmission mechanism, and the transmission mechanism drives the material roll to rotate through the active cone top 21. The detection mechanism includes a beamforming switch, and the beamforming switch includes a beamforming switch transmitter 23 and a beamforming switch receiver 24, and the beamforming switch transmitter 23 can be paired with the beamforming switch receiver 24; a plurality of beamforming switch transmitters 23 are provided on the active cone top 21. In this embodiment, five beamforming switch transmitters 23 are provided on the active cone top 21, of which four beamforming switch transmitters 23 are evenly distributed on the conical surface of the inactive cone top 21, and another beamforming switch transmitter 23 is provided in the middle position of the top surface of the cone; a circle of closely arranged and middle-positioned beamforming switch receivers 24 are provided on the passive cone top 22, and the five beamforming switch transmitters 23 can be paired with the five beamforming switch receivers 24 at the same time, and the two middle-positioned beamforming switch transmitters 23 are paired with the beamforming switch receivers 24, ensuring that the four outer beamforming switch transmitters 23 can find the corresponding beamforming switch receivers 24 in the up, down, left and right directions.
[0014] The principle of the utility model is as follows: when loading materials, the lifting and loading device lifts the material roll at the loading station. Before the center of the material roll coincides with the center of the cone top, the two shooting switches on the two cone tops cannot complete the matching. Only when the shooting switches on the two cone tops complete the matching, the shooting switches give a trigger signal to control the lifting and loading device to stop lifting. Finally, the two cone tops extend out and clamp at both ends of the material roll.
