Abstract
The utility model discloses a bed sheet leveling and deviation rectification system. A first photoelectric sensor and a second photoelectric sensor are symmetrically installed on two sides of the middle part of a bed surface, and a bed sheet penetrates through a slotted opening of each photoelectric sensor; a support is hung on a bedside and is sequentially provided with a first guide roller, a second guide roller, a third guide roller, a fourth guide roller, a first deviation rectification mechanism and a second deviation rectification mechanism from top to bottom; the vertical distance between each two adjacent guide rollers is 25mm, the horizontal distance between each two adjacent guide rollers is 15mm, the first guide roller and the third guide roller are arranged on the same side, and the second guide roller and the fourth guide roller are arranged on the other side. The bed sheet leveling and deviation rectification system can be used for solving the out of flatness and deviation problem of a new bed sheet, the running stability and reliability of the system can be improved, and the practicability is remarkable.
Description
Technical field
The utility model belongs to electromechanical integration technology area, relates to a kind of sheet leveling deviation-rectifying system.
Background technology
For a long time, medical resource is in short supply, some inspections of patient, and as B ultrasonic, CT etc., queuing phenomena is very serious, and in checking process, sheet is all manual replacing, has reduced to a certain extent the efficiency checking, has increased medical personnel's workload simultaneously.Thereby in checking process, cannot accomplish to check sheet " people one changes ".For above-mentioned present situation, provide a kind of novel Medical treatment examining table equipment that automatically more changes the sheet.The application of this equipment can guarantee to check sheet " people one changes ", review time and human resources outside occupying volume not again, and can discard sheet environmental protection and reclaim.
Yet equipment in use, whether sheet is smooth has a significant impact the stable operation of equipment with sideslip.Therefore need a kind of spare system, whether sideslip of sheet not only can be detected, and can flatten, rectify a deviation.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of sheet leveling deviation-rectifying system.
The utility model comprises the first photoelectric sensor, the second photoelectric sensor, the first guide pulley, the second guide pulley, the 3rd guide pulley, the 4th guide pulley, the first deviation correction mechanism, the second deviation correction mechanism and support.
The first photoelectric sensor and the second photoelectric sensor symmetry are installed on the both sides in the middle of bed surface, and sheet is through the flute profile mouth of each photoelectric sensor; Support hangs on the head of a bed, sets gradually from top to bottom the first guide pulley, the second guide pulley, the 3rd guide pulley, the 4th guide pulley, the first deviation correction mechanism, the second deviation correction mechanism on support; Adjacent two guide pulleys differ 25mm up and down, and left and right differs 15mm, and the first guide pulley and the 3rd guide pulley are positioned at the same side, and the second guide pulley and the 4th guide pulley are positioned at opposite side.
Each deviation correction mechanism comprises a pair of conical drum, connecting rod and the sleeve of electromagnet is housed, one of them conical drum is installed on support, another conical drum is connected by revolute pair with connecting rod, under the attraction of electromagnet, realize the swing of connecting rod, thereby realize the pressing of two conical drums with separated, a pair of conical drum in the first deviation correction mechanism is contrary with a pair of conical drum installation direction in the second deviation correction mechanism.
The utility model beneficial effect is as follows: the utility model has solved in general replacement sheet situation, the out-of-flatness that may exist and sideslip problem, thus improved stability and the reliability of equipment operation, there is significant practicality.
Accompanying drawing explanation
Fig. 1 is the utility model integral installation figure.
Fig. 2 is utility model error-correction structure figure.
In figure, 1. photoelectric sensor, 2. photoelectric sensor, 3. guide pulley, 4. guide pulley, 5. guide pulley, 6. guide pulley, 7. deviation correction mechanism, 8. deviation correction mechanism, 9. support, 10. conical drum, 11. conical drums, 12. connecting rods, 13. are equipped with the sleeve of electromagnet.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As depicted in figs. 1 and 2, sheet correction flattening mechanism, comprise photoelectric sensor 1, photoelectric sensor 2, guide pulley 3, guide pulley 4, guide pulley 5, guide pulley 6, deviation correction mechanism 7, deviation correction mechanism 8, support 9, deviation correction mechanism comprises a pair of conical drum 10,11, connecting rod 12, the sleeve 13 of electromagnet is housed.
Two photoelectric sensor symmetries are installed on the both sides in the middle of bed surface, and sheet is through the flute profile mouth of two sensors; Four guide pulleys are installed on support successively, and adjacent two guide pulleys differ 25mm up and down, and left and right differs 15mm, and four cylinder integral body are in "S" shape.
A conical drum in a deviation correction mechanism is installed on support, and another is connected by revolute pair with connecting rod, realizes the swing of connecting rod under the attraction of electromagnet, thereby the pressing that realizes two conical drums is with separated.Another deviation correction mechanism is rack-mount equally, is positioned at the below of guide pulley, and a pair of conical drum installation direction in two error-correction structures is contrary.
The utility model is used the course of work as follows:
As shown in Figure 1, sheet is the advanced photoelectric sensor of crossing in Renewal process, enters afterwards four guide pulleys, arranges, so after sheet walks around successively, can flatten because four guide pulleys are serpentine.
When photoelectric sensor has one sheet sideslip to be detected, signal will pass to singlechip controller, and controller is according to the sheet left and right number of believing one side only error correct mechanism.When finding that sheet departs from, electromagnet energising, upwards pulls connecting rod, thereby two conical drums is pushed mutually.Now, because the diameter of two ends cylinder is different, therefore, in the situation that rotational angular velocity is identical, the linear velocity of sheet two lateral movements is different, just can rectify a deviation.After sheet is corrected, the electromagnet power-off in sleeve makes two conical drum separation.Sheet left, the operation principle of correction is identical to the right.
