Description

Limit regulating device for stroke distance control {A limit regulating device for excursion­control}

The present invention is an improvement of the limit adjusting device for stroke distance control that can adjust the rotation or stroke (movement) distance of the reducer, which is widely used in general industrial machines, and more specifically, the dog which controls the limit switch is easily visible to the naked eye. By configuring it so that you can check it, you can provide convenience.

In general, the limit control device which can reduce the rotational force of the motor and move a certain distance with the driving force obtained from the reduced output shaft and automatically stop is widely used in the automatic opening and closing device of the vinyl house.

The limit adjusting device decelerates the rotational power of the output shaft and engages another gear in a direction perpendicular to the gear of the output shaft at the distal end of the driven shaft, and forms a screw in the gear shaft which is engaged with the dog. The limit switch is configured to move up and down along the screw shaft on both sides of the dog so that the dog can move up and down while the rotating shaft is in reverse rotation, and cut off the power of the motor. Inconvenient to use a tool, etc. In addition, it was not possible to use in a machine configuration requiring precision because the rotation or movement distance can not be precisely adjusted.

Thus, the present inventors have previously registered a limit control device (the utility model registration No. 0172538, No. 0213787) to solve the above problems.

However, the above-mentioned pre-registered design has a stacking position of the dog contacting each of the two limit switches, so that the user can check the position of the dog with the naked eye exactly from the front even when the cover is formed of a transparent material. It was difficult, and improvement was required.

The present inventors have completed the present invention with the technical problem of designing to provide an improved limit control device so that the dog can be easily identified from the outside.

That is, in the present invention, two dogs independently controlled by the rotation of the handle are independently configured as a means for solving the above technical problem, and the dogs are brought close to the transparent confirmation window (casing) to which the rotary knob is coupled to identify the dogs. By making it very easy to check in front of the user to provide ease of use.

Limit distance adjusting device (1) for stroke control provided by the present invention is to combine the transparent confirmation window (4) to both sides of the lower end of the front case (2) of the front and rear cases (2) and (3) divided into front and rear, A handle engaging hole 5 is formed in the center of the window 4 so that the handle 6 having the extended locking portion 6a is fitted to the transparent confirmation window 4 and the extended locking portion 6a of the handle 6, respectively. The female and male stop gears 5a and 6b formed are mutually engaged so that the rotation of the handle 6 is controlled.

Inside the handle 6 is formed a spring inlet 6c open to the rear to incorporate the spring (7) and to the outside of the spring (7) to form a first internal gear (6e), The guide bar 8b is coupled to the outer circumference of the guide bar 8 on which the axial hole 8a is formed so that the guide bar 8 is lifted in the axial direction, and extended to the outside of the first internal gear 6e. A second internal gear 6f is formed, and the second internal gear 6f is in contact with the operation interval 10 of the limit switch 9 fixed to the transparent confirmation window 4 and the case 2 at an outer circumference thereof. At least two planetary gears 13 axially coupled to the rotating body 12 in which the dog 11 is formed are tooth-coupled.

And the outer side of the rotating body 12 is disposed between the pair of mounting plate 15, 16 which is fitted to the support rod 14 formed in the casing 2, between the mounting plate 15, 16 The end is coupled to the axial bore (8a) of the guide bar (8) and two driven gears formed on the shaft (17a) is engaged with the planetary gear (13) coupled to the rotating body (12) The gear 18 and the input gear 22 which are installed in the front and rear cases 2 and 3 and are meshed with the output gear 20a of the reduction gear device 20 driven by the stationary motor 19 are integrated. The drive gear 21 is formed to be axially coupled to the driven gear 18.

In the drawing, reference numeral 23 shows a power supply for applying power to the limit switch 9 and the stationary motor 19.

The present invention, which can be configured as described above, can be used for the purpose of limiting the administrative distance by installing a device for reciprocating a certain distance in various industrial sites and the like, and the operation of the present invention will be described in detail below.

In other words, when the driving coarse power is applied in a state where the limit adjusting device 1 provided in the present invention is installed in a reciprocating machine at a predetermined distance, the driving force of the stationary motor 19 is transferred to the front and rear cases 2 and 3. The output gear 20a of the reduction gear device 20 rotates while being sufficiently decelerated and output by the reduction gear device 20 provided therein, and the input gear 22 which is tooth-coupled with the output gear 20a. Drive gear 21 integrally formed with the input gear 22 to rotate the two driven gears 18 at the same time, the rotation of the) is formed on the shaft 17 of each driven gear 18 The sun gear 17a transmits the driving force to the planetary gear 13 which is tooth-coupled with the second internal gear 6f formed on the handle 6.

When the driving force is transmitted to the planetary gear 13 as described above, the planetary gear 13 axially coupled to the rotating body 12 moves in the circumferential direction along the second internal gear 6f, wherein the dog 11 is moved. The rotating body is rotated so that the operating period 10 of the limit switch 9 is operated by the dog 11 to control the power supply of the drive motor 19.

To adjust the position of the dog 11 is built in the limit adjusting device 1 of the present invention is to rotate by pressing the handle (6). That is, when the handle 6 is pressed, the first internal gear contracts as the spring 7 embedded in the handle 6 fixed by the transparent confirmation window 4 and the female / female stop gears 5a and 6b is contracted. (6e) slides along the guide gear (8b) formed on the outer periphery of the guide bar (8) to free the rotation of the handle (6) in this state by rotating the handle (6) of the driven gear (18) Since the rotating body 12 in which the planetary gear 13 is axially coupled is rotated around the sun gear 17a formed on the shaft 17, the position adjustment of the dog 11 is made extremely easy. At this time, since the dog 11 is in contact with the transparent confirmation window (4), it can be easily confirmed with the naked eye when operating the handle 6, by using the handles on both sides (6) to adjust the position of the dog (11) This will set the desired stroke of the machine, etc. to be installed.

The present invention constructed and acted as described above allows the stroke adjusting limit adjusting device 1 to rotate by pressing the handle 6 to adjust the position of the dog 11, so that the dog 11 is coupled as in the prior art. It is configured separately without stacking the constituent members, and the position of the dog 11 is configured to contact the transparent confirmation window (4) to which the handle 6 is coupled, when the user rotates the handle (6) the dog with the naked eye (11) It is possible to check the position of the practical useful design that can be accurate positioning.
