Description

A filing motion detector

technical field

The invention relates to a filing motion detector, which belongs to the field of filing monitoring equipment.

Background technique

Patent 2017215688545 discloses a filing stability monitoring device. During filing, a sensor is used to detect whether the file is lifted/pressed down, and an alarm will be issued when the file is lifted/pressed down. Since humans are not machines, in the actual filing process, the force before and after the file cannot be guaranteed to be uniform at all times, so the above-mentioned devices often generate alarms in actual use.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

As shown in Figures 1 and 2, a filing motion detector includes a workbench, a controller, a display screen 3, a fixed seat and a detection head.

The worktable includes a worktable 1 and a backboard 2 fixed on one side of the worktable 1. The worktable 1 is a filing worktable, and a bench vice 5 is fixed. The controller is set on the worktable, generally placed on the worktable 1. In the control cabinet 6 at the bottom of the desktop, the display screen 3 is connected to the controller, and the display screen 3 is fixed on the backboard 2 to display the detection situation. Easy to take anytime.

The fixing base 7 is also arranged on the workbench, more specifically, it is fixed on one side of the workbench 1 , and faces the bench vice 5 . In order to facilitate fixing, the fixing seat 7 is a clamping seat, the clamping seat includes a base, one end of the base is connected with an L-shaped clamping seat, the transverse section of the clamping seat is parallel to the base, and a number of handle bolts are arranged on the transverse section of the clamping seat, It is used to fasten the clip base to the work table 1 .

The detection head includes at least three rows of sensors 9 and a bearing part 8 for carrying the sensors 9. The sensors 9 are reflective photoelectric sensors, all of which are cylindrical structures. All sensors 9 are connected to the controller. The bearing part 8 is arranged on the fixed seat through a lifting structure 7. Wherein, the distance between the top row of sensors 9 and the middle row of sensors 9 is equal to the allowable push-up range of the front/rear end of the file, and the distance between the bottom row of sensors 9 and the middle row of sensors 9 is equal to the file front/rear end. Allowable push down range , the spacing between adjacent sensors 9 in the same row is determined according to the actual situation.

As shown in FIG. 3 , the bearing portion 8 is a plate body, the sensor 9 is vertically fixed on the plate body, and the two ends of the sensor 9 are respectively located on both sides of the plate body. The sensor 9 is arranged in three rows, two in the top row, three in the middle row, and three in the bottom row, and the overall appearance is a "concave" shape.

As shown in FIGS. 4 and 5 , the lifting structure includes a slider and a rack guide rail vertically fixed on the fixed seat 7 , the bearing portion 8 is fixed on the slider 10 , and one side of the slider 10 is provided with a chute 15 . 15 The cross section is a right-angled trapezoid, the rack guide is an isosceles trapezoid structure, the rack guide is embedded in the chute 15, there is a triangular gap between the rack guide and the chute 15 at the right angle, and a matching brake block 12 is embedded in the gap. The slider 10 is also screwed with a fastener 11. The fastener 11 is a screw rod. The end of the screw rod extends into the chute 15 and is rotatably connected with the brake block 12. The inner shaft of the chute 15 is engaged with the rack guide rail. The gear 13 is fixed on the slider 10 with a driving device 14 for driving the rotation of the gear 13, and a common motor can be used.
