A pallet 2 is laid in each concrete/product manufacturing area 1A, and a formwork W into which concrete is poured is placed on the pallet 2.

The traverser 10 of the present invention includes a cart 4 that rolls along a first track 3 and a second track 16 that is laid on the cart 4 in a direction perpendicular to the first track 3 and extends toward one person in the manufacturing area. It is composed of an inner frame 5 that rolls horizontally, and an outer frame 6 that rolls horizontally along a third track 18 that is laid on a trolley 4 in a direction perpendicular to the first track 3 and extends to the manufacturing area 1A. ing.

The outer frame 6 is superimposed on the inner frame 5 and is attached to a third track 18 so as to reciprocate at a higher level than the latter.

The trolley 4 includes a traveling electric motor 13, a control panel 14, and a control device 1.
5, and runs on the first orbit 3.

The inner frame 5 is a rectangular frame with a length that is almost the same as the width B of the truck 4, and is equipped with wheels 17 that roll on a second track 16. It is made to protrude to the right from the end (the right end in the figure).

A second track 16 is also laid in the production area 1A for a length sufficient for this movement of the inner frame 5.

That is, the second track 16 includes a track section on the truck 4 and a track section laid in one production area.

Similarly, the third track 18 also has a manufacturing area 1 on the track section on the bogie 4.
It consists of a track section laid by people.

When the part of the second track 16 on the trolley 4 and the part one person above the manufacturing area are centered, the part of the second track 18 on the trolley 4 and the part one person above the manufacturing area are aligned. has been completed.

As will be explained later, the inner frame 5 is caused to reciprocate in the horizontal force direction by a drive mechanism, and the movement of the inner frame 5 itself drives the outer frame 6.

The outer frame 6 also has approximately the same length B as the inner frame 5, and wheels roll along the third track 18 so as to protrude from the end (right end) of the inner frame 5 by a distance slightly smaller than B. It has 19.

As will be explained later, the outer frame 6 is equipped with a lifting mechanism, and when placed in a low position, it is inserted into a recess 26 provided in the manufacturing area 1A at the bottom of the pallet 2, and when placed in a high position, it lifts the pallet 2. It is designed to be lifted off the floor of the manufacturing area and carried.

The drive mechanism for the inner frame 5 consists of a wire drum 12 attached to a truck 4 and a steel cable 7 wound around the wire drum 12.

One end of the steel cable T wound around the drum 12 several times is fixed to a metal fitting 21 attached near the right end of the inner frame 5, guided to the left via a pulley 22 at the right end of the inner frame, and attached to the left end of the trolley 4. It reaches the drum 12 via a pulley 23.

The other end of the steel cable 7 is a metal fitting 2 attached near the left end of the inner frame 5.
0 and reaches the drum 12 via a pulley 25 on the left end of the inner frame and a pulley 24 attached on the right end of the truck 4.

Therefore, when the drum 12 is rotated in the clockwise direction C, the inner frame 5 moves to the right, and when the drum 12 is rotated in the counterclockwise direction, the inner frame 5 moves to the left.

The drive mechanism for the outer frame 6 consists of two steel cables 8 and 9.

Although each of the steel cables 8 and 9 has one end fixed to the trolley 4, the other end fixed to the outer frame 6, and the middle part hung on a pulley on the inner frame, the two are arranged differently.

As shown in FIG. 2, the left end of the steel cable 8 is fixed to a metal fitting 21 attached to the left end of the trolley 4, and the steel cable 8 is guided to the right and hung on a pulley 28 attached to the right end of the inner frame 5, and the right end is attached to the outer frame 9. It is fixed to a metal fitting 29 provided at the left end of.

Therefore, when the inner frame 5 moves to the right, the outer frame 6 is also moved to the right by the steel cables 8.

The left end of the steel cable 9 is fixed to a metal fitting 30 installed at the right end of the trolley 4, and guided to the left by a pulley 31 installed at the left end of the inner frame 5.
After being hung on the frame, it is guided to the right and its right end is fixed to a metal fitting 32 installed at the right end of the outer frame 6.

Therefore, when the inner frame 5 moves to the left, the outer frame 6 is also moved to the left.

FIG. 3 shows a mechanism for raising and lowering the outer frame 6, in which wheels 19 for running the outer frame are attached to one arm of a bell crank 33.

The bell crank 33 is rotatably attached to the outer frame 6 by a pin 34, and its externally powered arm is connected to the drive rod 36 by a pin 38.

The drive rod 36 is a drive cylinder 35 attached to the outer frame 6.
is connected to by a pin 3γ, and is caused to reciprocate in the horizontal force direction.

Therefore, by actuation of the drive rod 36, the individual bell cranks 33
rotates to raise and lower the wheels 19 relative to the outer frame 6.

4 and 5 show a centering mechanism used when the cart 4 is placed sideways in the manufacturing area 1A.

A positioning blanket 39 made of an angle-shaped member is attached to the side wall 11A of the pit 11.

A positioning head 40 that engages with the positioning blanket 39 is slidably attached to the truck 4.

A horizontal reciprocating rod 42 is slidably inserted into a horizontal tubular support guide 43 attached to the cart 4, and a positioning head 4 is inserted at the right end.
0, and the left end is the piston rod 4 of the drive cylinder 41.
It is connected to 1D.

Therefore, when the trolley 4 is stopped at a position where the positioning head 40 faces the positioning blanket 39 on the pit side wall 11A and the positioning head 40 is engaged with the positioning blanket 39 by the drive cylinder 41, The trolley 4 can be accurately centered for one person in the production area.

In this state, the second and third tracks 16 and 18 on the truck are accurately centered with the second and third tracks in the manufacturing area 1A, respectively.

In operation, it is assumed that the traverser 10 is traveling along the track 3 without stacking the inner frame and the outer frame correctly on the top of the truck and carrying any cargo.

When the positioning head 40 comes to a position almost facing the positioning blanket 39, the cart 4 is stopped, and the positioning head 40
When engaging the blanket 39, the manufacturing area 1A
The cart 4 can be mounted horizontally with the center aligned with the center.

Therefore, when the drive drum 12 is operated and rotated in the clockwise direction C shown in FIG. 1, the inner frame 5 is pulled out to the right (FIG. 1B).

The outer frame 6 is pulled out to the right by the movement of the inner frame 5 by twice the movement of the inner frame 5 and placed in the production area.

In this case, if the wheels 19 of the outer frame 6 are raised in advance with respect to the outer frame 6, the upper surface of the outer frame 6 can be lowered.

When moving this low-profile outer frame 6 in the x direction in Figure 1,
The outer frame 6 can be inserted into the recess 26 in the lower part of the pallet 2 in the production area 1A.

Next, the drive cylinder 35 (Fig. 3) is operated to move the outer frame 6.
When the wheels 19 are lowered relative to the upper surface of the outer frame 6, the upper surface of the outer frame 6 rises, so that the cargo is supported via the pallet 2 and mounted on the outer frame.

Next, by rotating the drive drum 12 in the counterclockwise direction A, the inner frame 5 and the outer frame 6 can be returned to their positions on the cart together with the cargo.

Then, by pulling out the cart 4, the pallet can be transported to a desired position.

As described above, according to the present invention, the pallet cross-feeding member that reciprocates between the top surface of the cart and the manufacturing area is simplified in structure and is composed of a lightweight inner frame and outer frame, thereby improving the drive mechanism of the pallet cross-feeding member. Since it is simplified, the cost of the traverser can be significantly reduced.

Furthermore, since the outer frame 6 is delivered to the loading area at twice the speed of the inner frame 5, the movement of the traversing member is speeded up, which helps improve work efficiency.
