Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a three-dimensional automatic factory, and in particular, the assembly line can be made three-dimensional and changeable, easy to manage, easy to expand and renovate, and reduce the air conditioning load. Regarding the small number of three-dimensional automatic factories.

(Conventional technology) Conventionally, assembly and manufacturing factories for automobiles, electrical equipment, and various other types of equipment have generally been built in one-story or low-rise buildings with two or three floors in order to facilitate assembly line work using belt conveyors. Met.

However, in recent years, in order to make effective use of land, as shown in Figure 8, the goods production room a has been constructed on multiple floors, and a common goods storage room has been constructed along at least one side of the production room a on the multiple floors. A high-rise factory has also been proposed (Japanese Unexamined Patent Publication No. 56-13
No. 4162).

That is, an air conditioning stage (if), lighting equipment, and a production line g are installed in each article production room a on each floor, which is composed of a partition wall C1, a ceiling d, and a floor e. The actual receiving and passing of goods, etc. is carried out via the partition wall C.
This is done through an article transfer port i formed at a predetermined location, and the article transfer port i is formed in advance at a desired position depending on the process of the production line.

The above configuration enables construction in urban areas where land prices are high, making it possible to construct urban factories near consumption areas, which have recently been reconsidered.

(Problem to be Solved) However, the above-mentioned high-rise second field has the following problems.

■Since each floor is strictly separated by floor slabs integrated into beams, there are restrictions on changing the production line if the production line is partially three-dimensional (spanning upper and lower floors). .

■Air conditioning equipment must be installed on each floor5, which increases not only the equipment cost but also the maintenance cost.

■-h As shown in td, the article transfer port l is formed according to the height of the production line g, so even if the production line is changed, the installation location of the necessary article transfer port i will also be changed. It will be different. Therefore, when changing the production line g, the existing article transfer port i must be considered, making it difficult to respond to design changes.

■ Changing and relocating the production line takes time and effort, and
If we wanted to introduce new equipment that would exceed the floor height, it would be necessary to drill holes in some of the floor sliding members.

The present invention has been made in view of the above points, and its purpose is to propose a three-dimensional automatic factory that has a small air conditioning load, can easily accommodate changes in the design of the production line, and is optimal for an urban factory. There is something to do.

(Means for solving the problem in A4) In order to achieve the above object, the present invention provides a three-dimensional automatic machine comprising an assembly unit in which a production line is arranged on at least one side of a high-rise three-dimensional rack having a warehouse function. At the factory, the floor surface of the assembled unit was constructed from transparent and air permeable removable panel members.

Preferably, the above three-dimensional automatic factory is constructed without providing a partition wall between the three-dimensional rack and the assembly unit.

(Function) In the present invention, a high-rise three-dimensional rack having a warehouse function is [
It serves as a temporary storage facility for parts, work-in-progress, and finished products for moving vehicles, electrical equipment, and various other types of machinery.

Transparent and air permeable removable assembly units arranged in multiple layers on one side of this three-dimensional rack constitute each floor of the factory, and the production lines for the above-mentioned machinery and the like are constructed on these assembly units.

Then, the parts and the like are transported from the above-mentioned three-dimensional rack to the production line, where operations such as assembly and manufacturing are performed, and the finished products and the like are stored again in the above-mentioned three-dimensional rack.

Since the bottom surface of the assembly unit is transparent and air permeable as described above, the number and capacity of air conditioning and lighting equipment can be reduced during the above-mentioned work.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an embodiment of a factory according to the present invention, and the same figure (A
) is a plan view of the reference layer, (B) is a cross-sectional view of the whole, and (C) is a skeleton view.

As shown in FIGS. 1A to 1C, assembly units 2 are arranged in multiple layers on both sides of a high-rise three-dimensional rack 1 provided at the center.

The three-dimensional rack 1 has 6+- warehouse functions common to the multi-layer assembly units 2, and in this embodiment, no partition wall is provided between the three-dimensional rack 1 and the assembly units 2.

As shown in an enlarged view in FIG. 2(A), the assembly unit 2 is removably mounted on steel frames 2a arranged vertically and horizontally like a shag gym, and on the steel ff2a arranged in the beam direction of the steel frames 2a. It is composed of a plurality of panel parts 42b placed on the panel. The panel member 2b is made of a material having transparency and air permeability, and in this example is made of a grating.

In addition, instead of this grating, punching is used.

It may also be constructed by netting or the like.

Each layer of the assembly unit 2 thus formed is provided with an assembly conveyor (free flow conveyor) 31, a parts supply conveyor 41, an assembly robot 5, and other inspection robots (not shown) and palletizing robots (for palletizing work-in-progress and finished products). A production line consisting of robots, etc. will be constructed.

In addition, for example, if equipment such as robots that make up the above-mentioned production line or products being manufactured are so high that they collide with the ceiling only on the first floor, the ceiling located at that location, that is, the upper Problem 01 can be solved by removing the panel members that make up the floor of the floor. Even if the installation location of the equipment, etc. has to be changed due to a change in the production line, the design can be easily changed because it is only necessary to remove the panel member at the new installation location.

Furthermore, in this example, in order to send parts from the above-mentioned three-dimensional rack 1 to the above-mentioned parts supply conveyor 4, and to store work-in-progress and finished products assembled and manufactured on the above-mentioned production line into the three-dimensional rack 1, A stacker crane 6 is provided between the rack 1 and the assembly unit 2, which can move freely in horizontal and vertical directions.

At this time, as described above, since there is no partition wall, the stacker crane can be stopped at any position and the goods can be sent and received.

As shown in FIG. 1(A), a communication unit 8 including a piping shaft 7, an elevator EV, stairs, etc. is disposed on a portion of both sides of the assembly unit 2.

Also, around each layer of the assembly unit 2, as shown in Fig. 2(B)
As shown in the figure, various piping 9a for air conditioning, cold/hot water, etc., air supply/distribution related equipment, power/control panel 9b, etc. are consolidated, and a maintenance passage 9C is provided for these equipment and equipment in the assembly unit 2. A utility unit 9 is provided (see also FIG. 3). This maintenance passage 9
Similar to the assembly unit 2, C is constructed by removably arranging transparent and air permeable panel members such as gratings, punching, and netting, and this panel member is removed to open the space 9d as shown in the figure. The space 9d also functions as an ejection hole for equipment and a vertical passage during transportation.

Note that a part of the outer periphery of the assembly unit 2 can also be used as the above-mentioned utility unit.

In this way, by consolidating various types of piping, power/control panels, etc. into a utility unit, it is not only possible to easily expand, downsize, or remodel production equipment, but also to facilitate the maintenance of various types of piping, power/control panels, etc.・Inspection becomes easier.

Further, as described above, since both the assembly unit 2 and the utility unit 9 are simply panel members placed on a steel frame, they are easily adaptable to expansion or reduction of the factory scale.

In other words, it is possible to create a factory that corresponds to the scale of production simply by adding more steel frames.

Figure 3 shows an example of the configuration of the above production line, with the upper part of the page showing an example of the configuration in the case of a line-type assembly system suitable for single-item, low-mix, high-volume production, and the lower part showing a configuration example for high-mix, medium-to-medium-volume production. An example of a suitable cellular assembly system configuration is shown.

In the same figure, the same reference numerals as in FIGS. 1 and 2 indicate the same parts as in FIGS. For the assembly robot 5 in the case of the mold assembly method, a robot with multiple assembly functions is used. This multiple assembly function robot 5 is provided with a parts supply conveyor 4 and a chassis supply conveyor 31.

Figure m4 is a partially detailed view of the line type assembly method shown in Figure 3, with (A) being a plan view and (B) being a sectional view.

In FIGS. 4(A) and 4(B), an assembly pallet 10 is transferred onto the free flow conveyor 3, and work-in-progress and finished products are assembled and manufactured by the single assembly function robot 5 onto this assembly pallet 10. is placed. Further, the parts supply conveyor 4 performs functions such as delivering the parts tray 11 to the stacker crane 6, stacking and unstacking the trays 11, supplying parts to the single assembly function robot 5, and buffer stocking the trays 11. .

FIG. 5 shows, in three dimensions, an example of a flow showing an example of product distribution within a factory according to the present invention shown in FIGS. 1(A) to (C).

As shown in the figure, a lift 12 is provided between the assembly units 2 of each layer, and one of the production lines as shown in FIGS. 3 and 4 is configured over multiple floors (in this example, the second floor). You may.

That is, the panel member 2b at the location where the lift 12 is installed is removed to form a desired space, and articles can be moved vertically through the space.

If it becomes necessary to change the installation location of the lift 12 due to changes in the production line, remove the panel member located at the new installation location (dotted line in Figure 5) and install the lift 12 at that location. This makes it extremely easy to change the production line. Note that a panel member may be placed in the space where the lift 12 is currently installed to close the space, if necessary.

The above production line is constructed by connecting automated material hand equipment such as the parts supply conveyor 4 and stacker crane 6 with assembly robots 5 and inspection/palletizing robots through an advanced information network (not shown).
An attempt is being made to make it M.

Figures 6 (A), (B), and (C) are similar to Figures 1 (A) to (C).
3 shows an example of an air conditioning system for a factory according to the present invention shown in FIG.

First, in the present invention, as described above, since the floor surfaces of the assembly unit 2 and the unit 9 are constructed from air-permeable panel members, it is basically possible to perform air conditioning with full power χ1 using one air conditioning equipment. can. In other words, a whole air conditioning system is possible.

However, partial air conditioning may also be used in order to perform air conditioning more efficiently.

Specifically, there are the following.

Figure 6 (A) shows the overall air conditioning system, in which air is blown out from two parts and sucked in from the bottom, making use of the natural fall of air-conditioned cold air, so in winter, outside air is used for cooling.

Figure 6 (B) shows a partial air conditioning system in which the lower part is the air conditioning area and the upper part is the ventilation area.

FIG. 6(C) shows a system in which a special air conditioning system is partially added to the general air conditioning system shown in FIG. 6(A), and this system is applied to local booths such as clean rooms and constant temperature rooms.

In the case of only the whole air conditioning method shown in FIG. 6(A), air conditioning piping within the utility unit 9 is required only on the top and bottom floors, and no intermediate floors are required.

Also, in the partial air conditioning system shown in FIG. 6(B), air conditioning piping may be installed only in the utility unit 9 on the uppermost and lower floors of the air conditioning area. However, if the air conditioning area and ventilation area can be changed alternately, air conditioning piping will be installed in the utility units on the top and bottom floors of both areas. Depending on the air conditioning method employed in this manner, air conditioning piping may be installed as appropriate.

FIG. 7 shows a system example of halon fire extinguishing equipment as an example of the factory fire extinguishing equipment according to the present invention shown in FIGS. 1(A) to (C).

In this example, a smoke detector 13 such as an ion type or a photoelectric type is installed on the ceiling of the top floor of the assembly unit 2 and the top of the three-dimensional rack 1, and a separate part of the smoke detector 13 ( (not shown) is provided.

When the smoke detector 13 is activated, the fire extinguishing equipment is automatically activated, the siren 14 sounds, and halon is ejected from the injection head 15 to extinguish the fire.

In the above embodiment, the three-dimensional rack 11 assembly unit 2
．． Stacker crane 6, communication unit 8, utility unit 9. Various other structures can be standardized as prefabricated units, and the entire factory can be configured to match the production scale, reducing construction costs and construction time.

It should be noted that it is preferable to expand in the vertical direction and in the direction indicated by the hollow mark α in FIG. 1(C).

(Effects of the Invention) As detailed above, the three-dimensional self-working floor according to the present invention has a removable floor surface, so it is easy to three-dimensionalize the LL production line, and the production line including the three-dimensional production line It is also easy to change. Moreover, since the floor members can be kept to the minimum necessary, it is economical. Furthermore, since the floor surface of the assembled unit is constructed from an air-permeable panel member, the number or capacity of air conditioning equipment, etc., can be reduced. Therefore, equipment costs and maintenance costs are reduced, and maintenance work is also facilitated.

Regarding air conditioning, since the air-conditioned space, outside building surface area, and rooftop area are small, the load is 40 to 60% compared to a one-story factory.
%, it is easy to accommodate natural ventilation, and it is also possible to air-condition the entire space using air convection within a large space.

Furthermore, since the panel member is made to have transparency, multiple floors can be viewed from one floor, making it easier to monitor production lines and the like. Furthermore, it is no longer necessary to install lighting equipment on each floor, for example.

Furthermore, since the panel member is made removable, when transporting equipment, etc., the panel member can be removed to form a predetermined space, and the work can be carried out through that space. . If the panel member to be removed is placed near the actual installation location of the equipment, the transportation work after loading and unloading becomes easier.

In addition, after loading and unloading work, place a panel over the above space to prevent equipment and workers from falling! It is preferable to have a

Furthermore, if no partition wall is provided between the three-dimensional rack and the assembled unit, air can easily flow toward the three-dimensional rack, improving the air conditioning effect and the like.

Furthermore, articles can be transferred between the three-dimensional rack and the assembly unit at any location. As a result, it is possible to easily change the production line on the assembly unit.
