Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for simultaneously demolding concrete products cured and hardened in a civil engineering block molding frame in multiple rows.

Conventionally, when demolding a concrete product that has been cured and hardened in a civil engineering block forming frame, a worker taps a plate spring that locks the recess forming plates that are in close contact with the openings on both sides of the forming frame to disengage them. At the same time, the pallet was rotated in both directions to open it, and the tips of the hooks that interlocked with the depression forming plate were released from the bottom surface of the pallet to the outside, and the concrete in the molding frame was demolded downward. The drawback was that it was time-consuming and inefficient.

In order to eliminate the above-mentioned drawbacks, the present invention is a device that automatically demolds a large number of molding frames in parallel at the same time, which automates the demolding work of concrete products at the Budanku factory and achieves high efficiency. It is characterized by the fact that it is labor-saving.

Hereinafter, the structure of the present invention will be explained with reference to the drawings showing examples of the present invention.

A rail is installed on the upper end of the machine frame 1 of an appropriate width, and the automatic transfer trolley 2 is mounted on it so as to run in both directions, and a pair of retractable hanging shafts are installed at front and back positions on the lower surface of the automatic transfer trolley 2. A hollow underframe 4 is suspended parallel to both sides of the machine frame 1, and a large number of U-shaped rods 5 are installed at appropriate intervals front and rear at center line positions from the front to the rear inside the underframe 4. are vertically installed, and receiving plates 8, 8 are provided in the lower end of each U-shaped rod 5 to receive the shaft pieces T projecting from the front and rear upper ends of the molding frame 6, projecting in the front and rear direction. A pair of arm rods 9, 9 are located near the center of the inner surface of the lower side of the front and back.
' and the lower ends of the arm rods 9, 9' are pivotally connected, and the arm rods 9, 9 and the upper ends of the arm rods 9', 9', which face each other in the front and back, are connected by a horizontal axis 10.10'. A pair of front and rear cylinders 11, 1 on both sides
1 and cylinders 11', 11' are pivotally connected, and the rond of each cylinder is connected to the horizontal shaft 10.10', thereby forming the horizontal shaft 10.1.
0' to the outside, and the upper ends of the recess forming plates 12, 12' on both sides of the molding frame 6 on the horizontal axes io, io' so as to face the center of the interval between the U-shaped rods 5. A large number of engaging two-pronged claw rods 13, 13' are installed vertically, a product transfer conveyor 14 is installed on the other side of the machine frame 1, and a pair of push cylinders 17 are installed in the front and rear from the central upper position of the frame 4. , 17' hang down, and a pressing protrusion 18 facing the upper end of each molding frame 6 is provided on the lower surface.
A pressing rod 19 having a protruding structure is constructed so as to be installed on the rond of the cylinder 17, 17'.

In addition, 15 in the figure is the product receiving frame of the product transfer conveyor, 16,
16' indicates a pallet locking hook of the molding frame.

Next, the effects of the present invention will be explained with reference to the drawings of practical examples.

When demolding a concrete product that has been cured and hardened in the forming frame 6, a large number of forming frames 6 are sequentially transferred in parallel using a transfer conveyor connected to the 10,000 side end of the machine frame 1, and then stopped. The automatic transfer cart 2 is moved to a position above each stopped molding frame 6 and stopped, and then the underframe 4 is lowered to bypass the shaft piece 7 of the molding frame 6 of the receiving plate 8 of each U-shaped rod 5. After that, the underframe 4 is raised again, the shaft piece 7 is received on the receiving plate 8, each molding frame 6 is suspended at the same time, and the automatic transfer cart 2 is moved in the direction of the product transfer conveyor 14. Then, the cart is stopped at a position above the receiving frame 15 at one end of the product transfer conveyor 14, and the underframe 4 is lowered, so that the lower end of each forming frame 6 is placed above the receiving frame 1.
5, if the lower frame 4 is lowered, the forming frame 6
At the upper end of the recess forming plates 12, 12' on both sides of the
3 and 13' are engaged, and the forked claw rods 13 and 13' are guided outward, thereby connecting the concave portion forming plates 12 and 12' on both sides of each molding frame 6 and the pallet locking hooks 16 and 16. ' is rotated from the molding frame and disintegrated, and then the underframe 4 is raised again, and with the molding frame 6 suspended from the receiving plate 8, the pressing rod 19 is pressed downward and the pressing protrusion 18 on the lower surface is pressed. The concrete products in the forming frame 6 are thereby dropped and demolded, and each demolded forming frame is further raised and transferred to a form collection conveyor, and the demolded concrete product is transferred while remaining on the upper surface of the receiving frame 15. It is something to do.

Therefore, in the apparatus according to the present invention, it is possible to demold a large number of molds at once, and in order to push the product inside while the molds are suspended upward, the product transfer conveyor below This provides the remarkable effects mentioned above, such as making demolding work more efficient and labor-saving without applying any impact to the material 14 during compression.
