The present invention is provided with a manufacturing unit 10 having a mold 5 on the entrance side, where a casting operation using reinforcing steel W and concrete is performed. The manufacturing unit 10 is used to produce a variety of concrete products B (with or without reinforcing steel) up to 4200 mm and widths up to 1250 mm, as shown in FIG. 12), it is possible to lift the mold 5, rotate it hydraulically, and load the concrete products B on the pallet member K.

The manufacturing unit 10 is disposed below the fixed filling unit 200 and has a structure capable of moving forward and backward, which is capable of lifting up and down inside the frame 20 that is movable on the rail 15. ) Is mounted, and the inside of the mold (5) is filled with reinforcing steel (W) and concrete (C) is cast in an uncured concrete product (B), to be demoulded on the pallet member (K).

To this end, the manufacturing unit 10 includes a mold lifting means 30 for lifting up and down the mold 5, and a mold rotating means 50 for rotating the mold 5 by 180 °.

The manufacturing unit 10 is a rectangular door frame in which the lower edges are supported by four wheels 17 on a pair of rails 15 fixed to the floor of the workplace, as shown in side and front views in FIGS. 3 and 4. 20, the wheels 17 are forward and backward reversed by an electrically operated traveling motor 19.

In addition, the mold 5 is fixed on the vibrating table 12 disposed at the inner center of the frame 20, and shafts 12a formed at both end portions of the vibrating table 12 are formed in the frame 20. It is fitted to be rotatable through a bearing (not shown) in the lifting block 32 coupled to move up and down between a pair of vertical guides 22 extending up and down on both sides.

In addition, the wire rope 34 is connected to the upper side of the upper side of each lifting block 32, these wire ropes 34 are raised and lowered by the mold lifting means 30, which is the frame A hydraulically actuated mold elevating cylinder 36 is provided on the upper side of 20.

That is, the mold elevating cylinder 36 is fixedly arranged on the upper side of the frame 20, and as shown in Figs. 5 and 7, connecting a plurality of wire ropes 34 to the rod (36a) They are connected to the upper end of the mold elevating block 32 via a plurality of turning sheaves 38 each rotatably mounted to the frame 20. Therefore, the operation of the mold lifting cylinder 36 causes the wire ropes 34 to be pulled and / or unrolled, and the mold lifting block 34 connected thereto is vertically moved between the pair of vertical guides 22. And as a result, the vibrating table 12 of the vibrating section 70 and the mold 5 disposed thereon are raised and lowered.

In addition, the manufacturing unit 10 includes a mold rotating means 50 for rotating the mold 5 by 180 °, which is mounted on one side of the mold lifting block 32.

The rotary plate 56 fixes the rotary shaft 12a of the vibration table 12 at the center thereof. Since the rotating shaft 12a extends through a built-in bearing (not shown) of the mold lifting block 32, the rotating shaft 12a is rotated in accordance with the rotation of the rotating plate 56, and the rotating cylinders 54a and 54b. They are fixed so that the rear end of the cylinder body is rotatable through the hinge 58 in the casing 52, and the rods are arranged in close proximity to each other at regular intervals in the circumferential direction of the rotating plate 56.

The pair of rotating cylinders 54a and 54b cause the two rotating cylinders 54a and 54b to interact with each other to rotate the rotating plate 56 180 ° forward and backward. This is because the rod of the upper rotating cylinder 54a is advanced and the rod of the lower rotating cylinder 54b is moved from the state (position A) in which the rods are disposed at the lower edge portion of the rotating plate 56 in FIG. 6B). Rotate the rotating plate 56 by 90 ° to rotate to the middle B position, pull the rod of the upper rotary cylinder 54a from the B position, and push the rod of the lower rotary cylinder 54b to the upper side. When the rotating plate 56 is rotated to the C position, the rotating plate 56 rotates 180 ° to rotate the vibration table 12 and the mold 5 180 ° through the rotating shaft 12a.

However, on the contrary, when the rotary plate 56 is rotated from the C position to the A position through the B position, the vibration table 12 and the mold 5 are returned to their original directions.

In addition, the lower side of the mold 5 is provided with a vibrating unit 70 to give a vibration to the mold 5 to achieve the compaction operation of the concrete contained therein. As shown in FIG. 4, the vibrator 70 includes a vibrating table 12 located on a lower surface of the mold 5, and fixes the mold 5 on the upper portion thereof. The vibrator 70 is arranged in parallel with the plurality of vibration shafts 74a and 74b in the lower surface space of the vibration table 12 so as to be rotatable through the bearings 72, as shown in detail in FIG. 8. Each of the oscillating shafts 74a and 74b has a plurality of eccentric weights 76 fixed in the middle through the pinned bolts 78a and the nuts 78b.

In addition, each of the vibration shafts 74a and 74b has vibration motors 80a and 80b disposed at their ends, and the vibration motors 80a and 80b are opposite to each other in both directions of the vibration table 12. The shafts are movably connected to the vibration shafts 74a and 74b by sprockets 82 and chains 84, respectively.

Therefore, the operation of the vibration motors 80a and 80b rotates the vibration shafts 74a and 74b, respectively, which is caused by a plurality of eccentric weights 76 suspended on the vibration shafts 74a and 74b. 74a and 74b so that the centrifugal force of the eccentric weights 76 is imparted to the vibrating shafts 74a and 74b, respectively, so that the vibrating shafts 74a and 74b are rotated. Vibration is given to the vibrating table 12 which is fixed as possible. The standard frequency of vibration generated in the vibration table 12 electromagnetically changes the rotational speed of the motors 80a and 80b so that the optimum vibration can be set for each concrete product B. .

This operation is shown in FIGS. 18 and 19.

As described above, the present invention fills the mold C with the concrete C from the filling unit 200, and then the vibrating part 70 operates together with the concrete pressing part 90. After the filling of the concrete C is completed, the plurality of lifting cylinders 92 are rotated to position the pressing plate 94 on the upper surface of the mold 5, and the lifting cylinders 92 operate to mold the pressing plate 94. Press the concrete upper surface of (5), and then operate the vibration unit 70.

At this time, the vibration unit 70 is a plurality of vibration motors (80a, 80b) by operating the eccentric weights (76a, 74b) fixed to the vibration shaft (74a, 74b) by rotating the vibration shaft (74a, 74b) While rotating at high speed, vibration of approximately 75 Hz frequency is applied to the mold 5 via the vibration table 12.

When the vibration is applied in this way, the semi-dry uncured concrete (C) in the mold (5) is a compaction phenomenon, and after the compaction, the return operation of the pressing plate 94 is made again, the concrete hopper 205 The concrete is replenished by refilling from the concrete, and the compacting operation is repeated. Finally, the concrete is cast into the product B of a predetermined shape in the mold 5, and in this state, the concrete of the mold 5 (C) The surface is smoothly trowelled by the workers' hands, and excess concrete is removed from the mold (5).

As such, when the casting of the concrete by the mold 5 is completed, the bottom pallet member 252 enters the mold 5 and is fixed to the upper surface of the mold 5, as shown in FIG. 37. When the mold 5 and the pallet member K are thus joined, the first one is the bottom pallet member 252, and the bottom pallet member 252 is slidable wheel 256 on the pallet transfer rail 250. Because it is equipped with these.

The bottom pallet member 252 is inverted, i.e., the wheels 256 are directed upward into the mold 5 by the pallet charging unit 150, the bottom pallet member 252 is then As will be described, it has been moved by the pallet charging unit 150 from the return rail 320 on the upper side of the curing machine (300).

The bottom pallet member 252 is lowered from the return rail 320 by the pallet charging unit 150, and as shown in FIG. 38, the chain belts 172 provided on the pallet charging unit 150 rotate the motor ( 174 rotates on the arms 170a and 170b to horizontally move the bottom pallet member 252 loaded thereon to the upper side of the mold 5. In order for the bottom pallet member 252 to be moved to the upper side of the mold 5 as described above, the plurality of hydraulically actuated clamp cylinders 132 provided on both sides of the vibrating table 12 operate so that the fixture 136 having a? -Shaped cross section. These serve as the entrance guideway on the upper side of the mold 5 of the bottom pallet member 252.

This state is shown in FIG. 39, and as shown by the solid line in FIG. 11, when the rod 132a of the clamp cylinder 132 is lowered and the lower surface of the &gt; When the bottom pallet member 252 enters the top surface of the mold 5, the bottom pallet member 252 forms a guide surface that supports both edges of the bottom surface of the pallet member.

Accordingly, the bottom pallet member 252 is disposed overlapping the upper side of the mold 5, and after the bottom pallet member 252 enters the upper side of the mold 5, the clamp cylinder 132 operates. So that the rod 132a is raised, as shown by the dashed line in FIG. 11, and as shown in FIG. 40, the &quot; -shaped fixture 136 is downwardly centered on the hinge axis 138 and its upper surface. The bottom surface edges of both sides of the bottom pallet member 252 located above the mold 5 are pressed against the mold 5. Accordingly, the bottom pallet member 252 is firmly fixed to the upper surface of the mold 5 through the clamp cylinder 132 and the &quot; -shaped fixtures 136 operated thereby.

As such, when the bonding of the mold 5 and the bottom pallet member 252 is completed, the fabrication unit 10 operates the mold raising and lowering cylinder 36 to operate the vibrating table 12, the mold 5, and the upper portion thereof. The bottom pallet member 252 is raised, and at the same time, the mold rotating means 50 is operated so that the rotating cylinders 54a and 54b rotate the rotating plate 56, thus vibrating, as shown in FIG. The table 12, the mold 5, and the bottom pallet member 252 thereon are rotated 180 degrees.

As such, when the vibration table 12 and the mold 5 and the bottom pallet members 252 thereon are integrally rotated, as shown in FIGS. 42 and 43, the bottom pallet members 252 are located at the bottom thereof. ) And the mold 5 and the vibrating tables 12 are inverted in turn on the upper side thereof, in which state the hydraulically operated pusher cylinder 274 of the conveying means 270 can be operated. The frame 20 of the production unit 10 travels by the travel motor 19 and the wheel 17 to the point "P". When the "P" point is reached, the manufacturing unit 10 lowers the bottom pallet member 252, the mold 5, and the vibration table 12 by the operation of the mold lifting cylinder 36, and the bottom pallet The semi-dry uncured concrete product B cast from the mold 5 is demolded on the member 252.

In such a case, the wheel 256 of the bottom pallet member 252 is mounted on the pallet transfer rail 250 to operate the clamp cylinder 132 which couples the mold 5 and the bottom pallet member 252 to each other. After releasing the engaged state, the mold elevating cylinder 36 is operated to demould in a state in which uncured concrete products B are placed on the bottom pallet member 252.

After the demolding operation as described above, the production unit 10 raises the vibration table 12 and the mold 5 and at the same time the pallet loading unit 150 is raised by the operation of the pallet lifting cylinder 166, which As shown in FIG. 44, the upper pallet member 254 positioned on the return rail 320 at the entrance of the curing machine 300 as the plurality of arms 170a and 170b protruding forward of the platform 154 are raised. Lift it up. At the same time, when the rotary motor 174 is operated, the chain belt 172 is rotated and the upper pallet member 254 is pulled onto the arms 170a and 170b while the chain belt 172 is rotated.

Then, the manufacturing unit 10 moves back to the initial position, and lowers the vibrating table 12 and the mold 5 to return to the original position.

In this case, as shown in FIGS. 12 and 16, the pallet charging unit 150 is loaded with the upper pallet member 254, and the upper pallet member 254 has already topped the concrete product B. The spacer 258 for placing on the upper side of the bottom pallet member 252 mounted on the surface is provided on both sides thereof.

In this way, the manufacturing unit 10 carrying the upper pallet member 254 is again subjected to the cleaning of the mold 5 and the release agent, and then, concrete reinforcing hardware (not shown) is placed in the mold 5, and the mold (5) Concrete (C) is dropped from the hopper 205 of the filling unit 200 is filled up.

Then, the concrete pressing unit 90 and the vibrating unit 70 operates to compact the semi-dry uncured concrete C in the mold 5, and finally through the repeated compacting operation, the concrete in the mold 5 is finally compacted. Is cast again, the surface of the mold 5 is smoothly plastered, and excess concrete is removed from the mold 5.

Then, the upper pallet member 254 with the spacers 258 facing upward on the mold 5 enters by the pallet charging unit 150, and in this case, the upper pallet is operated by the operation of the pallet lifting cylinder 166. The member 254 is lowered to the upper position of the mold 5, and the stop cylinder 184 of the fall preventing means 180 is operated so that the latch 182 is engaged with the catching groove 186a of the catching bar 186. As a result, the platform 154 and the upper pallet member 254 are stably fixed. In this state, the chain belts 172 provided in the pallet charging unit 150 are rotated by the rotary motor 174 to horizontally move the upper pallet member 254 loaded thereon to the upper side of the mold 5.

Thus, while the upper pallet member 254 is moved to the upper side of the mold 5, the fasteners 136 of the &quot; -shaped cross section serve as guideways, as shown by the solid line in FIG.

Then, after the upper pallet member 254 enters the upper side of the mold 5, the clamp cylinder 132 operates so that the &quot; -shaped fixture 136 moves the upper pallet member 254 into the mold 5. It is to be firmly fixed to the upper surface of each.

As such, when the bonding of the mold 5 and the upper pallet member 254 is completed, the manufacturing unit 10 operates the mold lifting cylinder 36 to operate the vibration table 12 and the mold 5 and the upper portion thereof. The upper pallet member 254 is raised, and at the same time, the mold rotating means 50 is operated so that the rotating cylinders 54a and 54b rotate the rotating plate 56, and thus the vibration table 12 and the mold 5 And the upper pallet members 254 thereon are rotated 180 degrees.

As such, when the vibrating table 12 and the mold 5 and the upper pallet member 254 thereon are integrally rotated, the frame 20 of the manufacturing unit 10 to the point “P” of the conveying means 270. ) Travels and reaches the "P" point, the production unit 10 lowers the upper pallet member 254, the mold 5, and the vibration table 12 by the operation of the mold lifting cylinder 36.

Accordingly, the spacer 258 provided in the upper pallet member 254 is supported at the lower end by the side brackets 260 of the lower pallet member 252 on the lower side thereof, so that the concrete product is between the lower pallet member 252. (B) The concrete product B, which is placed on the bottom pallet member 252 and has already been demolded on the bottom pallet member 252, forming the lamination space S, is broken by the top pallet member 254. It is to form a space (S) that is not.

Thus, in this state, the semi-dry uncured concrete product B cast from the mold 5 on the upper pallet member 254 is demolded.

This demoulding of the product B is the same as that of the bottom pallet member 252. That is, when the clamp cylinder 132 is released to release the coupling state, and then the mold lifting cylinder 36 is moved upward, uncured concrete products B are formed on the upper surface of the upper pallet member 254. In the laid state, the concrete product B is demolded from the mold 5.

After the demolding operation as described above, the production unit 10 raises the vibration table 12 and the mold 5 and at the same time the pallet charging unit 150 operates to raise the lifting table 154, which is a plurality of arms. As the 170a and 170b are raised, another new upper pallet member 254 located on the return rail 320 at the entrance of the curing machine 300 is lifted up.

At this time, if the upper pallet member 254 is heard by the pallet charging unit 150, it is three stages to be stacked on the upper side of the bottom pallet member 252 and the upper pallet member 254 already stacked. Is another top pallet member 254, and if it is the bottom pallet member 252 being heard by the pallet charging unit 150, it is the bottom pallet member 252 and the top pallet member 254 already stacked. It can not be stacked on the upper side of the, will be newly placed on the pallet member transfer rail 250. In this case, it will be a two-stage stacking structure in which one top pallet member 254 is stacked on the bottom pallet member 252.

As such, the pallet members K provided to the pallet charging unit 150 have two stages of the concrete product B on the pallet member K by a proper combination of the bottom pallet member 252 and the upper pallet member 254. Multistage stacking up to 6 or more is possible. In this way, it is possible to multi-stage stacking to pass through the curing machine 300 while transferring a large amount of product (B) at a time to be curable at a time.

As such, the hydraulically-operated pusher cylinder 274 of the conveying means 270 is operated on the pallet member conveying rail 250 by pushing the multi-stored concrete products B to the inside of the curing machine 300 by one stroke. When put in, the stacked pallet members K and the concrete product B push the stacks of the previously stacked pallet members K and concrete product B as shown in FIG. 1. Pass 300, and in turn move and cure according to a preplanned program.

Then, at the exit of the curing machine 300, the stacks of the pallet member K and the concrete product B, which have been cured, are pushed out. As shown in FIGS. 21 and 45, the exit of the curing machine 300 is shown. It is discharged to the separation unit 400 by the withdrawal cylinder 450 located in the. In addition, the separation unit 400 lifts the concrete product B from these laminates through the collector 410 and lifts the pallet member K through the pallet inverting unit 430 to cure the curing machine 300.

In the return process, the pallet members K are cleaned while passing through the pallet sweeping part 700 while the surface contacting the mold 5 is cleaned, and is then in turn moved along the inclined portion of the return rail 320.

In this way, according to the present invention, it is possible to automatically produce a variety of concrete products (B) by the economical production while saving the cost of manual labor compared with the prior art can greatly improve the work productivity.

On the other hand, the present invention has been described in the above method of casting the concrete (C) in the mold (5) and then the worker by the manual work (Trowelling), the present invention is not limited to this.

The present invention can utilize the automated plastering unit (900) 950 as shown in Figure 46 or 47 for the plastering operation of the surface of the concrete product (B) as described above.

The plastering unit (AVM) 900 shown in FIG. 46 has a movable feed box 902 movable from the fixed hopper 205 to the mold 5 and a plastering portion 910 mounted at its front end.

It is equipped with a hydraulically actuated moving cylinder 912 mounted to a fixed support 914, the rod 916 of which is parallel to the transfer arm 920 with the movable feed box 902 and the plastering section 910 mounted at the tip. Is extended to be connected to a rear end of the feed box 902. Therefore, the feed box 902 and the plastering part 910 are movable from the fixed hopper 205 to the mold 5 by the operation of the moving cylinder 912, so that the fixed hopper is used when the present plastering unit 900 is used. The mold 5 does not need to be disposed directly below the 205. That is, as shown in Figure 46, the mold 5 is disposed away from the fixed hopper 205.

Instead, a feed box 902 is positioned at the bottom of the concrete outlet of the hopper 205 to receive concrete C, move to the top of the mold 5 by means of a hydraulically actuated moving cylinder 912 and then move the feed. The concrete (C) is discharged from the box 902 to the mold 5.

The bottom exit of the movable feed box 902 is provided with an opening and closing flap 906 to fill the concrete (C) contained therein on the mold (5), the capacity of the feed box 902 is approximately 1,500 It is enough to have a capacity of Kg.

On the other hand, the plastering portion 910 is the lowermost beam 924 can be moved up and down by the built-in lifting means (not shown), the beam 924 is on the two eccentric shaft 926 Suspended, the eccentric shaft 926 is driven by a hydraulic motor (not shown) such that the beam 924 pivots on the surface of the concrete.

Such a plastering unit 900 can be operated in the following cycle. First, during the operating cycle, the feed box 902 moves to the top of the mold 5 and uniformly fills the mold C with the concrete C by a predetermined amount. And, the excess amount of concrete C above the mold 5 is moved backward toward the mold 5 by the flap 906 of the feed box 902. This operation lasts approximately 15 seconds.

The surface of the concrete (C) filled in the mold (5) is about 3 to 5 cm higher than the height of the mold (5). Concrete C is compacted by vibration, and in this way the mold 5 is filled up to the top.

Then, the plastering part 910 is moved backward to the mold 5 side by the moving cylinder 912, and the finishing beam 924 is lowered onto the mold 5, and is swiveled on the surface of the concrete C, and the surface thereof. Finish the process. The finishing beam 924 is raised after the excess concrete is pushed out of the mold 5 to the outside thereof and then raised, and the excess concrete C separated and removed from the mold 5 is reused in the next cycle. . All these operations are hydraulically driven, which gives great technical reliability. In addition, by mechanizing the finishing work of the surface of the concrete product (B) it is possible to further reduce the manual load of the operator, and improve the work productivity.

The plastering unit (AVM) 900 as described above may use the secondary concrete having a different property from the concrete supplied to the mold 5 in the manufacturing unit 10. That is, concrete having different characteristics from the concrete provided from the fixed hopper 205 of the filling unit 200 is contained in the hopper provided in the plastering unit 900 and is contained in one mold 5 in turn. The concrete product (B) can be provided with concrete properties of different properties.

For example, first, the surface quality from the hopper of the plastering unit (AVM) 900 is good, the particle size is small, and expensive surface plastering concrete is first filled in the mold 5. At this time, the feed box 902 advances to the mold 5 and inputs a predetermined amount. Next, the plastering unit 900 is reversed, and from the fixed hopper 205 of the manufacturing unit 10, concrete having a different property from the surface plastering concrete, that is, the structural characteristic is superior to the surface plastering concrete. It can be filled to the upper side.

In this state, if the plastering unit 900 is advanced and the beam 924 finishes the surface of the concrete, and the concrete product is demolded on the pallet member K, the surface of the concrete product is smooth. The surface plaster is to be distributed, the inside is a structurally durable large particles of reinforcement concrete layer is formed to maintain a good appearance quality, it is possible to obtain a concrete product of a very solid structural quality.

In addition, if necessary, the surface of the reinforcing concrete layer from the plastering unit 900 is filled again with the surface plastering concrete again, both front and rear to form a surface plastering concrete layer only to form a structural concrete layer therein. It could be.

Therefore, the plastering unit 900 is an advantage that can be produced by automatically casting different types of concrete in a single product.

In addition, the present invention may use a plastering unit (CTS) 950 of another structure as shown in FIG. This plastering unit 950 does not have a movable feed box unlike the structure shown in FIG. 46. A stationary arm 956 is horizontally formed on a trolley 954 which is only movable on the rail 952, and a plastering part 960 is mounted at its tip.

Therefore, when the concrete C is uniformly filled in the mold 5 by a predetermined amount and compacted by vibration, the bogie 954 advances and the finishing beam 962 provided in the plastering part is formed on the mold 5. It is lowered, and the surface of the concrete (C) by turning to finish the operation. The plastering unit 960 may have the same structure and operation method as the plastering unit 910 described with reference to FIG. 46, and the finishing beam 962 may be pivoted by a hydraulic motor (not shown). The surface is finished, the excess concrete C is removed from the mold 5 by pushing it outwards, and then separated from the upper surface of the mold 5 by the reverse operation of the trolley 954.

Such a plastering unit 950 can be seen that it can be used in conjunction with the production unit 10 of the present invention described above. The plastering unit 950 as described above can be plastered in the same manner when the height of the mold 5 is not more than ± 10 cm from the standard.

Such plastering units 900 and 950 are all hydraulic components to minimize the manual labor by the operator.
