') is installed, and an entry/exit passage 6'through which the conveyance object 2'is received or released by an entry/exit conveyor 5'is provided in the firewall 4'.

At this time, a vertical fire shutter (7') that opens and closes the entry/exit passage (6') vertically on one side of the entry/exit passage (6') closes the entry/exit passage (5') in case of fire and fires between floors. It was common to prevent spread.

However, such a conventional method has a problem of having to bear an expensive installation cost because the firewall 4'has to be installed over the entire area from the bottom layer to the top layer of the vertical transfer system.

In addition, since it is not only the section necessary to prevent the spread of fire, but the vertical fire shutter (7') of all floors must be operated at the same time to prevent the spread of fire between floors, it cannot effectively prevent the spread of fire. Since the structure of the shutter 7'is complicated, reliability is low, and there is a problem that a lot of cost is required for maintenance and repair of equipment.

Furthermore, in order to prevent the spread of smoke to other floors through the booth (3'), by providing a blower and supplying power to generate wind, it is possible to prevent the movement of smoke between layers, but the main power or UPS power is cut off. If the blower does not operate due to the loss, there is a problem that may cause a large accident due to the movement of smoke between layers.

In order to fully understand the present invention, operational advantages of the present invention, and objects achieved by the implementation of the present invention, reference should be made to the accompanying drawings illustrating preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, the present invention will be described in detail by describing a preferred embodiment of the present invention with reference to the accompanying drawings. The same reference numerals in each drawing indicate the same member.

FIG. 2 is a schematic view of a vertical transfer system according to an embodiment of the present invention, and FIG. 3 is a perspective view showing a horizontal fire shutter according to an embodiment of the present invention, and a carriage lift passage opening and closing unit is opened. It is a view showing the state, Figure 4 is a view showing a state in which the carriage lifting passage opening and closing unit is closed in the horizontal fire shutter of Figure 3, Figure 5 is an enlarged view of the fire protection plate and the differential shutter portion (A) of Figure 3 It is a perspective view, and FIG. 6 is an enlarged perspective view of the fire protection plate of FIG. 5, and is a view illustrating a lower plate in a state in which the upper plate is omitted.

As shown in these drawings, the vertical transfer system according to an embodiment of the present invention includes a carriage 10, a lifter 20, and a horizontal fire shutter 40.

First, the carriage 10 supports the object to be conveyed, and lifts and descends between a plurality of floors along the carriage hoistway (CP, see Fig. 3), that is, by raising and lowering the object 2 to be conveyed. It serves to return.

Next, the lifter 20, as shown in FIG. 2, is provided through a plurality of layers and serves to elevate the carriage 10, and the carriage elevating unit 21, the counterweight elevating unit 22, and , A lifter linear member, and a mast frame (Mast Frame, 25), and a driving unit (26).

The carriage lifting unit 21 is coupled to one side of the carriage 10 to lift the carriage 10 together while being elevated by the driving unit 26, and the counterweight lifting unit 22 includes the carriage lifting unit 21 and It is connected by the timing belt 23 to reduce the load of the driving unit 26 moving the carriage lifting unit 21 while lifting in the opposite direction to the carriage lifting unit 21.

Briefly describing the operation of the lifter 20 with reference to FIG. 2, the driving unit 26 operates to move the timing belt 23 connecting the carriage lifting unit 21 and the counterweight lifting unit 22 in a desired direction. By moving, the carriage 10 connected to the carriage lifting unit 21 can be transferred to a desired floor.

At this time, the mast frame 25 is disposed through a connection passage P formed between two adjacent layers up and down over a plurality of layers, and acts like a skeleton of the lifter 20, while raising and lowering the carriage. Since the unit 21 and the counterweight lifting unit 22 serve as a rail that guides the lifting and descending without shaking, the carriage lifting unit 21 and the counterweight lifting unit 22 inside the mast frame 25 A lifter passage (LP, see FIG. 3) for guiding the elevation of the) is formed.

In such a vertical conveyance system, a carriage elevation passage (CP, see FIG. 3) and a lifter passage (LP, see FIG. 3) are formed in the connection passage P, so that a fire generated from a lower floor when a fire occurs through such a passage goes to the upper floor. Because it can spread, it is necessary to prevent the spread of fire between floors for safety.

In general, since the carriage lift passage (CP) forms an empty space so that the carriage 10 can move up and down, it may be possible to block to some extent by providing an opening and closing device. However, in the case of the lifter passage (LP), several types of lifters are linear. Since the members are arranged along the vertical direction, there is a difficulty that cannot be simply blocked.

Particularly, in the case of a fire, it may be possible to block it to some extent, but in the case of smoke, it may spread to a small gap, so it is more difficult to completely block it.

Therefore, according to the present invention, by providing the horizontal fire shutter 40 to be described below, it is possible to prevent the spread of fire and the interlayer of smoke as much as possible along the lifter passage LP as well as the carriage lift passage CP. .

The horizontal fire shutter 40 is provided in a connection passage (P, see Fig. 2) formed between two adjacent layers up and down and serves to block the connection passage (P) in case of a fire, and is installed for each floor. Unlike the case of the vertical transfer system, it is possible to select and close the connecting passage of the desired section.

For example, if a fire occurs on the first floor, the conventional vertical transfer system requires that all vertical fire shutters installed in the entry/exit passages of all floors be operated at the same time to prevent the spread of fire between floors. There is an inefficient problem of wasting unnecessary energy to operate.

However, according to this embodiment, if only the horizontal fire shutter provided between the first and second floors is operated, the fire generated on the first floor can be prevented from spreading to other floors, so it is more efficient than the conventional vertical transport system. It is possible to prevent the spread of fire.

Furthermore, according to this embodiment, by closing the connection passage (P) of each floor, the booth (3), which is a passage for conveying the object to be transported across a plurality of floors, can be disconnected for each floor, so that the inside of the booth (3) Since the spread of fire can be prevented at the source, there is no need to install a separate firewall outside the booth (3).

As described above, according to the present embodiment, by providing the horizontal fire shutter 40, there is no need to install a separate firewall, thereby minimizing the cost of installation, maintenance, and repair of equipment, and more efficiently preventing the spread of fire. You can do it.

This horizontal fire shutter 40, as shown in detail in FIGS. 3 and 4, includes a fire shutter base 50, a carriage lift passage opening and closing unit 60, and an interlayer shielding unit 70.

For reference, FIG. 2 is a schematic diagram for explaining a vertical transfer system according to an embodiment of the present invention, so that one carriage 10 is shown as a view in which one carriage 10 moves up and down, but the horizontal fire shutter 40 of FIG. 3 Is used in a dual-type vertical transfer system that can lift two carriages facing each other, so two carriage lift passages (CP) are arranged in a symmetrical manner.

However, the present invention is not limited to the dual-type vertical transfer system as shown in FIG. 3, and may be applied to a single-type vertical transfer system that lifts and lowers one carriage shown in FIG. 2.

The fire shutter base 50 is provided on one side of the connection passage (P, see FIG. 2), and the carriage hoistway opening/closing unit 60 slides to open and close the carriage hoistway CP.

The carriage lifting passage opening and closing unit 60 serves to selectively open and close the carriage lifting passage CP through which the carriage 10 moves up and down, and is slidably coupled to the fire shutter base 50 so that the carriage lifts and descends by a sliding operation. The passage CP is selectively opened and closed.

3 and 4, the operation of the carriage passage opening/closing unit 60 will be described, as shown in FIG. 3, the carriage lifting passage opening and closing unit 60 is spaced apart from the carriage lifting passage CP. By positioning, the carriage lift passage CP remains open, but as shown in FIG. 4, when a fire occurs, the carriage lift passage opening/closing unit 60 approaches the carriage lift passage CP by sliding movement. The carriage hoistway (CP) is closed.

As described above, in the vertical conveyance system according to the present invention, since the carriage lifting unit 21 raises and lowers while supporting the carriage 10 from the side, a separate lifter linear member disposed in the vertical direction in the carriage lifting passage CP Since the lifter linear member is not arranged and only the lifter passage (LP) is disposed, the carriage lift passage (CP) is simply closed by the sliding operation of the carriage hoistway opening and closing unit (60) to prevent the spread of fire and smoke between layers. do.

On the other hand, the interfloor shielding unit 70 is coupled to at least one of the carriage lifting passage opening and closing unit 60 and the mast frame 25, and the mast when the carriage lifting passage opening and closing unit 60 closes the carriage lifting passage CP. It serves to block the movement of smoke through the lifter passage (LP) formed by the frame 25, and includes a fire protection plate 700, and differential shutters (800, 900).

The fire protection plate 700 is coupled to the mast frame 25 to block a part of the lifter passage LP, and at least one differential opening and closing region (TZ, PZ, see FIG. 5) surrounding at least one lifter linear member. It serves to form and includes an upper plate 710 and a lower plate 730.

The upper plate 710 and the lower plate 730 are disposed to be in contact with the upper and lower portions of the differential shutters 800 and 900 to be described later, respectively, but when contacting the differential shutters 800 and 900, the differential shutters 800 and 900 ) Is arranged to surround a predetermined area of the edge.

6 is an enlarged perspective view of the fire protection plate of FIG. 5, and is a view illustrating the lower plate 730 in a state in which the upper plate 710 is omitted.

The lower plate 730 is provided with a differential shutter seating groove 731 in which a predetermined portion of the differential shutters 800 and 900 is seated by a sliding operation of the differential shutters 800 and 900.

In addition, a shielding gasket seating groove 735 is provided at one side of the shielding shutter seating groove 731 in which a shielding gasket 733 for blocking smoke by contacting the shielding shutters 800 and 900 is mounted.

With this structure, when the difference shutters 800 and 900 approach and contact the fire protection plate 700 by a sliding operation, the difference shutters 800 and 900 are seated in the difference shutter seating groove 731 and the difference shutter ( As the shielding gasket 733 is in close contact between the 800 and 900 and the lower plate 730, smoke is prevented from passing therebetween.

Meanwhile, the differential shutters 800 and 900 are coupled to one side of the carriage hoistway opening/closing unit 60 to slide together according to the sliding operation of the carriage hoistway opening/closing unit 60, so that at least one differential opening/closing area (TZ, PZ) ) Is selectively opened and closed, and is provided with a number corresponding to at least one shielding opening/closing area TZ and PZ.

Here, the at least one shielding opening/closing region TZ, PZ includes at least one timing belt differential opening/closing region TZ surrounding the timing belt 23 (see FIG. 2 ), as shown in detail in FIG. 5, and a power cable. It includes a power cable shielding opening/closing area PZ surrounding (not shown).

In an embodiment of the present invention, as shown in detail in FIG. 5, at least one timing belt differential opening/closing region TZ is a pair of timing belt differential opening/closing regions spaced apart from each other, and for at least one timing belt The differential shutters 800 are spaced apart from each other to correspond to the pair of timing belt differential opening/closing regions TZ, and are provided as a pair.

The timing belt difference opening/closing area in the center is a passage through which the carriage lifting unit 21 moves up and down, and the timing belt difference opening/closing area on the left side provided with the same size is a passage through which the counterweight lifting unit 22 moves up and down.

In addition, since the power cable difference opening/closing area PZ is a place where a power cable (not shown) occupying an area smaller than the carriage lifting unit 21 or the counterweight lifting unit 22 is disposed, it is smaller than the timing belt difference opening/closing area TZ. It was prepared by area.

Corresponding to such a differential opening/closing region, the differential shutters 800 and 900 close at least one timing belt differential opening/closing region TZ to block smoke, and at least one timing belt differential shutter 800, and a power cable isolation It includes a differential shutter 900 for a power cable for blocking smoke by closing the opening/closing area PZ.

In one embodiment of the present invention, the description is limited to the timing belt and the power cable, but the present invention is not limited thereto, and when various lifter linear members are arranged, various types of differential opening and closing regions and differential shutters corresponding thereto. May be provided.

As described above, since the carriage lift passage CP forms an empty space so that the carriage 10 can move up and down, it may be possible to block to some extent by providing an opening and closing device, but a timing belt formed in the lifter passage LP In the case of the differential open/close area (TZ) and the power cable, the timing belt 23 and power cable (not shown), which are lifter linear members, are arranged in the vertical direction in the central area.
