In the anti- It is necessary to perform complicated operations in the Orient.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is a technical object of the present invention to improve the conveying efficiency by not requiring a wide installation space and simplifying the operation.

(MEANS FOR SOLVING THE PROBLEMS)

The above-described technical problems can be effectively solved according to the present invention. That is, the present invention relates to an electro-optical device comprising two rows of disc rows arranged in parallel in a direction substantially orthogonal to an electric center axis, each row being rotated about a horizontal central axis, A plurality of rollers which are set at 180 占 circumferential direction symmetrical positions of the electric discs and are rotated about an axis substantially perpendicular to the original one, And a pallet for use in the elevator take-in and take-out device, wherein the pallet is capable of passing between two rows of circular rows of the elevator take-and-go apparatus in the direction of the row row, And a pair of flanges which are set on both sides of the main body and supported on a laureine which is parallel to a substantially horizontal direction with respect to each other of the electric elevator take- And a plurality of notches through which each roller can pass are formed in correspondence with the arrangement intervals of the respective disks of the electric source row heat.

The present invention is based on the assumption that first and second elevators installed on upper and lower stages of a conveyer in the elevator box as described in the description of the prior art are carried in and out of the elevator.

The row halves are installed along the horizontal conveying direction of the pallet, and the rollers provided on the discs of the row halves support the flanges on both sides of the pallet and horizontally move the pallets by rotating them. The pallet is moved up and down.

That is, in each circle row, the rollers provided at 180 占 circumferentially symmetrical positions on the respective discs are in a state of being substantially horizontally concurrently with each other, and the pallets are formed by a pair of flanges provided on both sides of the body, It is supposed to be supported on an electric lawn. Thus, by synchronously rotating the disks of the respective row and column, the electric angle rollers are on the same phase with respect to each other of the disks, and move in the circumferential direction while maintaining the state of being substantially parallel to each other, The pallet is moved up and down.

At this time, if the Laura supporting the flange is in the ascending process, the non-supporting side roller arranged at a 180 ° circumferential symmetrical position with the Laura is in the descending process, and conversely, when Laura supporting the flange is in the descending process The roller of the non-supporting side is in an ascending process, but the non-supporting side roller passes through the notch formed corresponding to the interval of each disk to the electric flange and does not interfere with the flange, so that the pallet moves smoothly by the rotation of the disk.

In the elevator loading and unloading apparatus of the present invention, more preferably, the discs of the respective rows are disposed at irregular intervals (irregular intervals). As described above, the plurality of notch pitches formed on the flange of the pallet correspond to the disposing intervals of the respective discs of the electric circle rows, and therefore, the electric notches are also formed at irregular intervals.

When the electric cut-outs are formed at regular intervals, the positions of the respective rollers of the comb bearers for supporting the flange at the time of horizontally transporting the comb bearers, which are rowar lines arranged at a constant pitch, There is a possibility that the pallet falls down. However, such inconvenience can be prevented by making the cutout at irregular intervals.

In addition, since the interval between each disc and the interval between the cuts correspond to each other, even when the disc is at an irregular interval, in the ascending movement of the pallet due to the synchronous rotation of the discs of the disc, Is effectively prevented.

In the elevator take-off device according to the present invention, it is further preferable that two rollers are disposed adjacent to each other on the same circumference at symmetrical positions of 180 占 in the circumferential direction of the discs in the disc row. That is, in the case where the discs are provided with one roller at 180 占 circumferential direction symmetrical positions in the circumferential direction, even if the discs are arranged at irregular intervals as described above, the cutouts in the flanges of the pallets are formed at the corresponding intervals, In the process of horizontally moving the electric furnace in each circle, there is a possibility that the pallet is dropped due to the position of the roller and the cutout being matched. However, the electric furnace is divided into two by a straight line passing through the center of the electric disk, By disposing them symmetrically with each other, such dropout can be reliably prevented. Further, in the raising and lowering movement of the pallet, the two rollers on the non-supporting side can sequentially pass the electric cutout in the circumferential direction.

(Embodiments of the Invention)

Fig. 1 shows a preferred embodiment of the elevator take-in and take-out apparatus 10 and the pallet 20 according to the present invention and its operation. Fig. 2 shows the elevator 30 In the case of using as a carry-in / carry-out means for the load on the load.

Banchulip as shown in the Figure 1 device (10), (10 ₁ and 10 ₂₎ 4, each horizontal main shaft is rotated around the S _o the side-by-side arranged in a direction orthogonal to the electric main axis S _o in the substantially horizontal direction, Two circular arrays (only circular arrays on one side are shown) which are to be the original disks 11 are shown. Electrical angle of the disc circumferential direction 180˚ symmetrical position, each of the two low-R _1, R ₂ and R ₃ in (11), and R ₄ is to be arranged adjacently to each other on the same circumference, each roller R ₁ ~ R ₄ is an electrical angle disc (Approximately horizontally) with respect to the original side of the main body 11, as shown in Fig. The electrical disks 11 are synchronously rotated so that Laura R ₁ to R _{4 provided} in each of them are in phase with each other.

The elevator 30 shown in Fig. 2 is basically the same as that shown in Fig. 6, that is, the elevator box 31 is provided with a space of a predetermined height capable of accommodating the pallet 20, And a mounted super-vial 32a and a vial coupler 32b are disposed.

The interval h between the roller R ₁ and R _{2 of the take-in} and outlet device 10 and the roller R ₃ and R ₄ at 180 ° circumferentially symmetrical positions of the disc 11 with respect to the roller 11 and the roller pair B 32a and 32b ) In the second embodiment. Also banchulip device on the first floor of banchulip device (10 ₁₎ and second layer (10 ₂₎ are respectively provided opposite the exit half and half exit of the second floor of the first floor in the elevator to rank the source (30).

The pallet 20 includes a main body 21 on which a load is placed and a main body 21 extending horizontally on both sides of the main body 21 so as to be parallel to the horizontal directions of the respective disks 11 of the take- A pair of flanges 22 (only one flange is shown in Fig. 1) supported on the rollers R ₁ , R ₂ or R ₃ , R ₄ . Four cutouts 22a are formed in the flange 22 so as to allow the electric angle rollers R ₁ to R ₄ to pass therethrough at intervals corresponding to the arrangement intervals of the disks 11 of the electric source row heaters.

1 (a), each of the discs 11 of the take-in / take-out device 10 is rotated by the rollers R ₁ and R ₂ in the direction of the axis of the disc 11 The pallet 20 is stopped at the lowermost position on the circumferential orbital centered at S _o and at the uppermost position on the electric arc trajectory by the 180 ° symmetrical roller R ₃ and R ₄ , The flanges 22 are supplied to the disks 11 while being supported on the lower rollers R ₁ and R ₂ . The supply of the pallet 20 is performed as the rollers R ₁ and R ₂ are rotated around the axial center thereof. The pallet 20 is positioned in advance so that the trajectory of each cutout 22a of the flange 22, which moves upward according to the operation described below, overlaps with the overlapped position of the electric arc circumference trajectories of the rollers R ₁ to R ₄ .

In this state, as shown in FIG. 1 (b), when each disk 11 starts synchronous rotation in the direction of the arrow in the middle, the rollers R ₁ to R ₄ are rotated about the main axis S _o of each disk 11 And rotates according to the circumference. In this case, R _1, R ₂ on the lower side, so the rotation movement to the upper roller by R ₁ the preceding flange (22) pallets (20) is lifted by the electric low-R _1.

Therefore, the pallet 20 is prevented from interfering with the roller R ₃ and R ₄ by the flange 22, and the roller R ₁ and R ₂ are positioned at the uppermost position on the circumferential orbit as shown in FIG. 1 (d) The disk 11 is moved upward by a distance corresponding to the height h as the disk 11 is rotated 180 degrees.

The pallet 20 raised to the position shown in FIG. 1 (d) is horizontally moved by the rollers R ₁ and R ₂ rotating around the center of the axis, and the pallet 20 is moved horizontally While the lower rollers R ₃ and R ₄ are rotated around their axis, and a new pallet (not shown) is supplied onto the rollers R ₃ and R ₃ .

Since the flanges 22 of the pallets 20 to be delivered at this time are supported by both of the adjacent R ₁ and R ₂ , even if the notch 22a is caught on one of the electric rollers R ₁ and R ₂ during the horizontal movement, The flange 22 is supported by the roller so that the pallet 20 does not fall. The same is true for the horizontal movement when a new pallet is supplied on the lower rollers R ₃ and R ₄ .

When the pallet 20 is lowered in the state shown in Fig. 1 (d) in the state shown in Fig. 1 (d), the opposite operation (reverse rotation of the original 11) The rotational direction of the disc 11 can always be made the same.

When a plurality of load balancers W are continuously transported from the one-story hoistway F ₁ to the two-layer hoistway F ₂ by using the above-described loading / unloading apparatus 10 as the loading / unloading means of the load on the elevator 30 2 (a), the n-th load balanc W _n is placed on the concrete bail 32a in the lift box 31 of the elevator 30 and the pallet 20 ₁ And the lift box 31 reaches the entrance and exit of the second floor.
