Description

Bobbin detection device

Technical Field

The utility model relates to a be applied to section of thick bamboo yarn spool detection device on doffer creel.

Background

The automatic doffing is one of the important functions of the full-automatic high-speed false twist texturing machine. When the package is fully wound, the creel lifts the fully wound package, the chuck is then released, and the package rolls along the track into the yarn storage for removal by a worker. According to the design, the yarn storehouse can store two yarn packages at most, and when the number of the yarn packages exceeds two, the yarn creel only lifts the yarn packages, and the clamping discs are not loosened. The stop bracket shown in fig. 1 is used for stopping the bobbin at the position by pushing the bobbin when the bobbin rolls to the position along the track, and just triggering the detection switch when the bobbin stops at the position where the bobbin stops after rolling into the yarn storage, and sending a signal to a control system of the device. The existing detection switch is shown in figure 2 and comprises an installation plate 1, an inclined hole seat 2, a compression leg 3, a compression sheet 4 and a microswitch 5, wherein a self-tapping screw 6 is used for fixing the microswitch 5. When the yarn drum rolls down, the yarn drum presses the pressing column 3, the pressing column 3 drives the pressing sheet 4, the pressing sheet 4 triggers the microswitch 5, and finally signal transmission is finished. As can be seen from fig. 2, the internal components of the existing detection switch are exposed to the outside, so that the situation that the pressing column 3 is locked due to over-tight installation or burrs are formed on the pressing column 3 and the pressing sheet 4 frequently occurs, so that signal errors are caused, and the yarn bobbin unloaded to the bobbin bin cannot be normally detected.

Disclosure of Invention

The invention aims to: the utility model aims at providing a bobbin detection device with low failure rate and stability and reliability.

The technical scheme is as follows: the bobbin detection device comprises a closed shell, wherein an integrated connecting rod and a microswitch are arranged in the closed shell, the integrated connecting rod comprises a straight section and a J-shaped bent section which are connected, the other end of the straight section is rotationally arranged in the closed shell through a rotating shaft, and the other end of the J-shaped bent section extends out of the closed shell; when the integral link is pressed to rotate downward, one end rotating around the shaft presses the micro switch.

The utility model discloses in, change original open mounting panel into closed shell, the integral type connecting rod unites two into one original compression leg and preforming in other words, including all parts are all wrapped up by closed shell, the shell is inside to have sufficient space to let micro-gap switch and integral type connecting rod free activity, does not receive the influence of uninstallation back section of thick bamboo yarn, can not lead to the card to die because of the installation is too tight to improve the reliable and stable nature that detects, reduced the fault rate.

Furthermore, a spring is installed at one end of the integrated connecting rod rotating around the shaft, so that the integrated connecting rod is reset. The connecting rod can be completely retracted by a spring when bounced, so that the elasticity of the swing arm of the microswitch is not required, and the service life of the microswitch can be prolonged.

Furthermore, a spring hook seat is arranged in the closed shell, a hook is arranged at one end of the integrated connecting rod rotating around the shaft, one end of the spring is fixed on the hook, and the other end of the spring is fixed on the spring hook seat.

Furthermore, a positioning column is arranged on the side face of the closed shell and used for being matched with a positioning hole in the stopping support, and the correct installation position of the bobbin detection device is guaranteed.

Furthermore, the closed shell is provided with a fixing hole and is fixed on the stop bracket through a bolt.

Further, the fixing hole is located above the J-shaped bending section groove of the integrated connecting rod. Because the bolt is arranged in the fixing hole, when the integrated connecting rod rotates upwards to reset, the bolt can play a role in upper limit.

Has the advantages that: compared with the prior art, the utility model, have following advantage: each part is arranged in the closed shell, the integrated connecting rod and the microswitch can freely move in the closed shell, the phenomenon that the integrated connecting rod and the microswitch are blocked due to over-tight installation is avoided, the reliability of the detection device is high, and the failure rate is low.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 3 to 5, a bobbin detection device comprises a closed housing 7, wherein an integrated connecting rod 10, a microswitch 5, a spring 11 and a spring hook seat 12 are arranged in the closed housing 7, the integrated connecting rod 10 comprises a straight section and a J-shaped bent section which are connected, the other end of the straight section is rotatably arranged in the closed housing 7 through a rotating shaft, and the other end of the J-shaped bent section extends out of the closed housing 7. The one end that integral type connecting rod 10 pivoted is equipped with the couple, and spring 11 one end is fixed on the couple, and the other end is fixed on spring couple seat 12, and spring 11 is used for making integral type connecting rod 10 reset. In addition, the side of the closed shell 7 is provided with a positioning column 8. The closed shell 7 is provided with a fixing hole 9, the fixing hole 9 is located above the integrated connecting rod 10J-shaped bending section groove, and the closed shell 7 is fixed on the stop support through a bolt.

The microswitch 5 is depressed, switch OFF, and the signal is on. The microswitch 5 is ON when bouncing up, and the signal is off. The integrated connecting rod 10 can swing up and down by taking the rotating shaft as the center, when a bobbin is pressed by a bobbin, the integrated connecting rod 10 swings down to press the swing arm of the microswitch 5, so that a signal of the microswitch 5 is triggered, and meanwhile, the spring 11 is also stretched. When the bobbin is taken down, the spring 11 contracts to drive the integrated connecting rod 10 to swing upwards to the original position, at the moment, the swing arm of the microswitch 5 is also loosened, and the microswitch 5 does not trigger a signal any more.
