DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the configuration, function and operation of a lock pin pin driving apparatus for securing a pallet according to the present invention will be described with reference to the accompanying drawings. It should be noted, however, that the same reference numerals are used for the same or similar components throughout the drawings.

In the following description, terms such as 'first', 'second', and the like are used to distinguish constituent elements whose technical meaning is within the same range for convenience. That is, any one configuration may be arbitrarily referred to as a 'first configuration' or a 'second configuration'.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, therefore, are not to be construed as limiting the technical spirit of the invention. It is to be understood that the invention is not to be limited by any of the details of the description to those skilled in the art from the standpoint of a person skilled in the art that any or all of the drawings shown in the drawings are not necessarily the shape,

Referring to FIG. 1, the apparatus 100 for locking a lock pin pin for fixing a pallet according to an embodiment of the present invention can be used to carry and lift a mechanical part, which is inconvenient to carry by a human force, like an automobile assembly line. In the illustrated embodiment, the rocking pin driving apparatus 100 is configured to place the pallet 200 horizontally moved in the bogie 300 at a predetermined position on the lift L. The lock king pin driving device 100 is installed at the top of the lift L.

2 shows a part of the lock-pin drive device. The lock king pin driving device is installed on the base plate 10.

The base plate 10 is in the form of a flat plate, typically in the form of a substantially rectangular plate. The thickness and shape of the base plate 10 may be variously changed depending on the design of the automobile assembly line.

On the top of the base plate 10, a rolling means 11 is provided. A plurality of rollers exposed at the upper end of the rolling means 11 support the lower end of the pallet bearing the mechanical part, allowing the pallet to move horizontally. In the drawing, the pair of rolling means 11 are arranged in the longitudinal direction, but a plurality of rolling means may be provided in the lateral direction depending on the lateral width of the pallet 200.

The height of the rolling means 11 is determined by the size of the brackets and rollers that mount the rollers through the bearings so that each roller can freely roll.

The locking pin 30 remains at a position lower than the height of the rolling means and rises higher than the rolling means 11 when the horizontally moved pallet 200 reaches the position by the rolling means, And inserted into the fitting space 210 formed at the lower portion (see FIGS. 7 and 6). Whereby the pallet 200 is fixed on the base plate 10. [ At this time, the height of the lock king pin driving apparatus 100 is lower than that of the rolling means 11, so that it does not interfere with the insertion and removal of the pallet 200.

Figs. 2 to 5 relate to the configuration of the lock-pin drive device.

The driving apparatus 100 according to the embodiment of the present invention includes a base plate 10, a pin housing 20, a locking pin 30, a rolling roller 40, and an operating lever 50.

The pin housing 20 is fixed on the base plate 10, and a pinhole 21 opened upward is formed. The inside of the pin housing 20 is cylindrical in correspondence with the lock king pin 30. The locking pin 30 is restrained by the pinhole 21 and can move up and down.

The pin housing (20) is formed with a passage hole (22) opened in the lateral direction. This passage hole 22 is formed by being cut from the lower end of the pin housing 20 which is a cylindrical shape.

The locking pin 30 is a cylindrical member mounted inside the pin housing 20. The upper surface of the locking pin 30 protrudes upwardly and can easily access the fitting space 210 of the pallet 200.

A mounting hole 31 is formed in the lock king pin 30 so as to open in the left and right direction corresponding to the passage hole. The mounting hole 31 is formed in the same direction as the passage hole 22.

When the lock king pin 30 mounted on the pin housing 20 is appropriately rotated, the passage hole 22 and the mounting hole 31 can be aligned with each other, thereby forming a space opened in the left and right direction.

The rolling roller 40 is mounted between the facing inner surfaces constituting the mounting hole of the lock king pin.

In the mounting structure of the rolling roller 40, a shaft hole 32 passing through the inner surface of the mounting hole 31 vertically is formed in the lower portion of the lock king pin 30. The rolling roller 40 is formed to be larger than the diameter of the shaft hole 32 and is coupled to the shaft member 41 coupled to the shaft hole 32 while being positioned inside the mounting hole 31.

Thus, the rolling roller 40 is located inside the mounting hole 31 and can freely rotate, and moves up and down integrally with the lock king pin 30. [

In the drawing, a pair of assemblies of the lock king pin 30 and the pin housing 20 are provided, and they are arranged side by side so that the passage hole 22 and the mounting hole 31 are aligned. Although not shown, the spacing and number of assemblies lying on a straight line may be adjusted differently depending on the number and position of the fitting space formed in the pallet.

The operating lever 50 is a length member arranged to pass through the mounting hole 31 of the locking pin 30 and the passage hole 22 of the pin housing 20 mounted on the base plate. The operation lever 50 is slidable in the left-right direction. A guide hole 51 is formed in the operation lever 50 so that the rolling roller 40 contacts the inner surface.

The rolling roller 40 and the locking king pin 30 are lifted or lowered in the pin housing 20 along the guide hole 51 of the operating lever 50 sliding along the upper surface of the base plate 10 horizontally .

The operation lever 50 is in the form of a standing plate passing through the mounting hole 31 and the passage hole 22 of the assembly of the locking pin 30 and the pin housing 20 provided separately . The operation lever (50) is formed with guide holes (51) having different height at both ends.

At this time, the rolling roller 40 is positioned inside the guide hole 51, and the rolling roller 40 is brought into contact with the lower surface or the upper surface of the guide hole 51 as the operating lever 50 is moved leftward and rightward The lock pin is raised or lowered while rotating.

Both ends 511 of the guide hole 51 are formed horizontally along the upper surface of the base plate 10 and the middle portion 512 is formed to be inclined by connecting ends having different height. The upward movement of the rolling roller 40 and the locking pin 30 is made by the intermediate portion 512 having an inclination. After the maximum descent or the upward movement, the rolling roller 40 Is supported. Therefore, even when an external force acts to push the lock king pin 30 down or to move upward, when the maximum or the maximum fall, the upper surface or the lower surface of the horizontal end of the guide hole 51 The locking pin 30 does not descend or rise arbitrarily.

The lower end surface of the operation lever 50 is provided with a rail 54 and a guide block 55 for allowing the left and right sliding movement of the operation lever 50 to be stabilized.

Specifically, a length groove 52 recessed upward is formed on the lower end surface of the operation lever 50. The depth recesses of the longitudinal grooves 52 can be formed deep without interfering with the formation of the guide holes 51 by forming the longitudinal grooves 52 between the both guide holes 51. [ The rail 54 and the guide block 55 can be installed without increasing the height of the operation lever 50 by limiting the section in which the length groove 52 is formed between the guide holes 51 .

A mounting base 53 having a width larger than that of the operation lever 50 is coupled to the bottom surface of the longitudinal groove 52. The mounting table 53 has a sufficient width so that the guide block 55 or the rail 54 can be firmly engaged. The mounting table is also associated with a sensor for detecting the position of the operating lever. The sensor will be described later.

The rail 54 and the guide block 55 are located in a space between the lower surface of the mounting table 53 and the base plate 10. [ Although the rail 54 is shown mounted on the base plate 10 and the guide block 55 is shown coupled to the mounting table 53 in the figure, .

The rails 54 are arranged to coincide with the left and right directions of the operation lever 50. The guide block 55 is slidably coupled to the rail 54. Here, the rail 54 and the guide block 55 may be replaced by a linear motion member such as a well-known LM guide.

The operation lever 50 is provided with the longitudinal groove 52 at the lower portion of the operation lever 50 and the mounting table 53, the guide block 55, the rail 54, The operation lever 50 can be moved smoothly in the left and right directions while the height of the operation lever 50 is kept constant. These members for assisting the movement of the operating lever 50 are disposed below the operating lever 50 so that the space occupied by the driving apparatus 100 on the plane of the base plate 10 can be reduced. That is, the spatial allowance for installing various devices or equipment such as the rolling means 11 on the base plate 10 is increased.

The guide hole 51 and the rolling roller 40 are positioned at the lower center of the locking pin 30 so that the upward force of the rolling roller 40 by the guide hole 51 is fully transmitted to the locking pin 30. Therefore, the force required to operate the lock pin can be minimized, and the fatigue accumulation of the related members can be reduced, thereby providing a long service life.

On the other hand, the driving apparatus 100 may include, in a further configuration, a restoring portion 60 that elastically urges the operating lever 50 in one direction so as to maintain the raised state of the locking pin 30. [ The configuration for pushing the operating lever in one direction includes a spring or the like coupled to the longitudinal end of the elastic lever.

As described above, the rising of the locking pin causes the pallet bearing the mechanical part to be positioned on the base plate. If the locking pin is lowered optionally, there is a danger that the right pallet and the mechanical part move on the rolling means. Especially, when the lock is released by the lock pin during the process of lifting the machine parts to the assembly position by operating the lift, safety accidents caused by falling of the pallet and the mechanical parts in the lift may occur.

The restoring portion 60 always keeps the locking pin 30 protruded from the pin housing 20 when an external force does not act, thereby preventing the aforementioned safety accident.

In the illustrated embodiment, the restoration portion 60 includes a fixed block 61, a length bar 62, a support block 63, and a coil spring 64. The fixed block 61 and the long rod 62 are coupled to the base plate 10 and the support block 63 is fixed to the operation lever 50.

The long rod 62 extends in the fixed block 61 in parallel with the moving direction of the actuating lever 50.

The support block 63 is fixedly projected from the side surface of the operation lever 50, so that the height of the operation lever 50 is not increased. The support block 63 is formed with a through hole 631 through which the end of the length bar passes. The distance between the fixed block 61 and the support block 63 is changed because the movable rod 62 moves left and right in the through hole 631 in accordance with the left and right movement of the operation lever 50. [

The coil spring 64 is wound on the outer circumferential surface of the long rod 62, and one end portion thereof supports the fixing block 61 and the other end thereof is supported by the support block 63. As the coil spring 64 is wound on the length bar 62 in the compressed state, it acts in the direction of pushing the support block 63 to the left with reference to the drawing. Therefore, if no external force is applied, the operation lever 50 is held in a state of being pushed to the left side of the drawing, and the lock king pin 30 is kept in an elevated state in the pin housing 20.

The restoration part 60 having the structure proposed by the embodiment of the present invention makes it possible to construct the restoration part 60 on the base plate 10. [ In addition, since the space occupied by the restoration part 60 is reduced as much as possible, a large space for mounting other components on the base plate 10 is provided.

And further includes a sensor unit 70 for sensing the operation of the driving apparatus 100. When the pallet is moved over the base plate 10 by the rolling means 11, it is difficult to visually confirm whether or not the locking pin 30 is in a protruded state because it is covered by the pallet 200. When the upper end of the protruding lock king pin 30 and the end of the entering pallet 200 come in contact with each other when the pallet 200 moves to the upper portion of the base plate 10 in a state where the lock pin 30 protrudes, Can be damaged. The sensor unit is important in that even if the user does not observe the lock pin directly, it is possible to know whether or not the lock pin is ascended or descended.

The sensor unit 70 includes a cradle 71 provided on the base plate 10 and a first position in which the locking king pin protrudes and a second position in which the locking king pin 30 descends into the pin housing 20 And a pair of detection sensors 72 mounted on the cradle 71 in correspondence with the left and right movement distances of the operation lever 50.

In the illustrated embodiment, the sensing part 531 protruding in correspondence with the pair of sensing sensors is formed on one side of the mount 53.

Here, the non-contact type position detection sensor is used as the detection sensor 72. [ For example, an ultrasonic sensor, a magnetic sensor, or the like can be used.

As the operating lever 50 moves to the left or right, the sensing portion 531 comes close to any one of the sensing sensors 72. The detection sensor 72 senses that the sensing unit 531 is approaching a predetermined distance or more and outputs an electric signal. The output electric signal is subjected to signal processing as already known, have. Alternatively, when the pallet is loaded on the lift in an automated manner, it can be controlled to proceed to normal operation or to stop operation according to an electrical signal.

Hereinafter, the operation of the drive system will be described with reference to FIGS. 6 and 7. FIG. 6 and 7, the pallet 200 is shown in phantom. A pair of fitting spaces 210 are formed in the pallet 200.

Fig. 6 relates to a state in which the locking king pin 30 projecting into the fitting space 210 is engaged.

The operating lever 50 is moved to the left in a state in which the supporting block 63 is pushed to the left by the restoring force of the coil spring 64 in Fig.

It is confirmed that the sensing part 531 provided on the mounting table 53 is located adjacent to the left sensing sensor 72. [

In FIG. 6A, the rolling roller 40 is moved to the right end of the guide hole 51. The rolling roller 40 and the locking pin 30 are raised in the pin housing 20 as the right end of the guide hole 51 is formed higher than the left end. Even if the operating lever 50 is moved to the right side arbitrarily even when the locking pin 30 is pressed in the upper portion, the rolling means 11 and the lock king pin 30 30 do not descend.

7 is a diagram related to a state in which the locking pin is lowered.

An external force is applied to the left end of the operation lever 50, where the external force is generated by the operator directly pressing the left end of the operation lever, or through another mechanical device.

In Fig. 7 (b), as the operating lever 50 moves to the right, the supporting block 63 moves to the right side together with the operating lever 50, and the coil spring 64 is compressed. The energy of the compressed coil spring 64 is used to move the operation lever 50 to the left when the external force is released.

On the other hand, the sensing unit 531 provided on the mounting table 53 is close to the sensing sensor 72 located on the right as the operating lever 50 moves to the right. The detection sensor 72 on the right side recognizes that the sensing unit 531 is close to the user and informs the operator or the like that the locking pin 30 is descending.

In FIG. 7 (a), the operation lever 50 is moved linearly by a guide block moving on the rail 54. The rail 54 and the guide block 55 can be restrained such that the operation lever 50 is not moved in the vertical direction.

The rolling roller 40 descends through the inclined middle portion 512 of the guide hole 51 and eventually remains at the right end. The rolling roller 40 and the locking pin 30 descend while moving along the inclined intermediate portion 512 to be lower in height than the rollers provided in the rolling means 11. [ Therefore, the locking pin 30 does not interfere with the pallet 200 moving on the rolling means.

The driving apparatus 100 of the lock king pin according to the embodiment of the present invention is configured such that the lock pin 30 is lifted and lowered by a mechanical structure.

If a fluid such as compressed air or high-pressure fluid is used to lift the lock pin, the compressor and wiring should be installed to circulate the working fluid, but not in an environment where the up-and-down movements are limited as in the upper part of the lift. In addition, the wiring structure in which the working fluid flows must be installed in the vicinity of the lift and the work environment becomes complicated. The present invention eliminates various problems caused by using a working fluid by mechanically constructing it.
