Conventional vertical transportation devices used for vertical conveyance of flat items such as LCDs are provided with a plurality of up-down units at appropriate intervals to stably support the edges or edges of the flat items. A ball screw device or LM guide is commonly used as the down unit.

However, since only one ball screw device or LM guide is operated by one power source, a conventional vertical transportation device requiring a plurality of ball screw devices and an LM guide requires a plurality of power sources. In this case, it is difficult to temporarily drive each ball screw device or LM guide, and the power transmission system becomes very complicated. In addition, since a large installation area is required to arrange a plurality of power sources, there is a disadvantage that the size and weight of the device is caused. For this reason, there is no small vertical transportation device which can move the installed place to and fro as needed.

The present invention has been devised to improve the above-mentioned disadvantages, and the power transmission system is simpler than the conventional one, and as a whole, the device is made smaller and lighter, it is easy to transfer the installation place, and several devices can be simultaneously used as one power source. It is an object of the present invention to provide a power divergent vertical transport apparatus that can be driven.

In addition, the present invention has another object to provide a power divergent vertical transport apparatus that can be accurately maintained the horizontal state of the package.

In addition, the present invention has another object to provide a power divergent vertical transportation device that is easy to change the design according to the size or weight of the package.

The power divergence vertical transport apparatus of the present invention for achieving the above object effectively includes one power generating means, a power branch means in which the rotational force supplied from the power generating means is branched into a plurality of components, and is supplied from the power branch means. It can be configured to include a plurality of lifting means that are driven simultaneously by each of the divided components. (Claim 1)

Further, the elevating means is fastened to one side of the vertical belt, a timing pulley rotatably installed at the upper and lower ends of the vertical frame, a timing belt wound around the timing pulley, and a package to support a package. It may be composed of a support. (Claim 2)

In addition, the support is a fixed piece fixed to one end of the timing belt, a support piece fixed to the other end of the timing belt, and the fixing piece so that the coupling characteristics between the timing belt and the timing pulley can be improved It may be composed of a spacer installed through the support piece. (Claim 3)

In addition, the power branch means has a first branch portion where the rotational force supplied from the power generating means is branched into two components, and the component force supplied from the first branch portion is again branched into two smaller components and output in both directions. It may be composed of a second branch. (Claim 4)

In addition, the power generating means may be composed of a motor and a drive gear mounted to the drive shaft of the motor. (Claim 5) In some cases, the drive gear may be mounted on the output shaft of the reducer while connecting the reducer having a conventional structure in which the rotational force inputted from the motor may be converted by 90 ° and output.

In addition, the first branch portion of the power branch means is composed of a first driven gear that is engaged with the drive gear and a first rotating shaft coupled to the first driven gear and a second driven gear coupled to both ends of the first rotating shaft. The second branch of the power branch means may be coupled to the third driven gear and the third driven gear in engagement with the second driven gear of the first branch, and the timing pulleys of the elevating means may both end portions. It may be configured as a second rotating shaft coupled to the shaft. (Claim 6)

In addition, a contact / non-contact switch / sensor for automatically switching the rotation direction of the timing pulley so as to control the lowest falling position and the maximum rising position of the support may be installed at the upper and lower ends of the vertical frame, respectively. have.

According to this configuration, each lifting means can be driven simultaneously by a plurality of components separated from one power source. Further, by clamping or releasing the spacer of the support, it is possible to precisely level the package on the support and vertically transported. In addition, when a large number of driven gears are installed on the first rotary shaft of the first branch part as necessary and additionally installed the second branch part of the above-described configuration for each of the driven gears, a package having a larger area may be placed in several places. I can support it.

Therefore, the design can be changed very easily according to site conditions.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the power divergent vertical transport apparatus according to an embodiment of the present invention.

Example

Attached Figure 1 shows a planar configuration of the power divergent vertical transport apparatus according to the present embodiment, Figure 2 shows a side configuration of the power diverter vertical transport device shown in Figure 1, Figure 3 is an embodiment This is an enlarged view of the timing belt connection of the power divergence vertical transport system.

As is well shown in the figure, the power divergence vertical transport apparatus of this embodiment uses a total of four lifting means 40 to support the package, and the planar arrangement is also rectangular.

The elevating means has a timing belt 43 surrounded by an outer side of the timing pulley 42 provided at the upper and lower ends of the vertical frame 41. In particular, the supporter 50 for supporting the package is fastened to one side of the timing belt. In addition, horizontal frames are fixed between the vertical frames, thereby achieving structural stability.

In addition, the support 50 is a fixing piece 51 fixed to one end of the timing belt and the support piece 52 fixed to the other end is connected by a bolt-shaped spacer 53 When the gap adjuster 53 is clamped or loosened, the gap between the fixing piece and the support piece is narrowed or widened. Therefore, the coupling characteristic between the timing belt and the timing pulley is changed by the operation of tightening or releasing the spacer, and the vertical height of the spacer can be adjusted little by little to maintain the package in an accurate horizontal state.

On the other hand, in this embodiment, the power generation is composed of a conventional motor 10 and the drive shaft of the motor is inserted into the output direction is changed by 90 ° and the bevel gear type drive gear 11 mounted on the output shaft of the reducer Means were used, the first driven gear 21 of the first rotation shaft 20 is engaged with the drive gear 11 so that the first rotation shaft also rotates when the drive gear rotates.

In this way, when the first rotary shaft rotates, the second driven gear 22 mounted at both ends of the first rotary shaft 20 rotates, and the third driven gear has a third of the second rotary shaft 30. As the driven gear 31 is engaged, the timing pulleys 42 provided at both ends of the second rotation shaft rotate. Therefore, when the motor is driven, the support 50 mounted on one side of the timing belt reciprocates between the maximum ascending height and the minimum descending height, and the package is conveyed in the vertical direction.

As described above, in the power divergence vertical transportation device according to the embodiment of the present invention, the branching force branched from one power source (motor) is supplied to each lifting means, so that the timing pulley is rotated at the same time to adjust the driving timing of the lifting means. You do not have to try.

In addition, since the rotational force of the motor is transmitted to the elevating means through a power branch means having a very simple structure composed of only a rotating shaft and a driven gear, the device can be miniaturized / lightened.

In addition, it is possible to accurately maintain the horizontal state of the package by a simple operation of tightening or releasing the spacer adjuster mounted on one side of the timing belt.
