Description

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

Conventionally, when demolding a concrete product that has been cured and hardened in a molding frame, a worker taps the upper end plate springs of the recess forming plates that are in close contact with the openings on both sides of the molding frame to disengage them and rotate them in both directions. The product inside is removed from the mold by moving the pallet locking hook that interlocks with the concave part forming plate away from the bottom surface of the pallet inside the molding frame.This removal operation is time-consuming and highly efficient. There was a drawback that the work could not be completed.

In order to eliminate the above-mentioned drawbacks, the present invention is an apparatus for automatically demolding a large number of molding frames at the same time while arranging them in parallel, making the demolding operation for taking out products in a block factory highly efficient and labor-saving. It is characterized by the fact that it can be transformed into

Hereinafter, the configuration of the present invention will be explained with reference to practical example diagrams.

A rail 2 is installed in the left-right direction on the upper surface of the machine frame 1 of an appropriate width, and the first automatic transfer trolley 3a and the second automatic transfer trolley 3b are mounted so as to be able to move automatically in the left-right direction. 3a

A rectangular frame rod 5 is hung horizontally from the front to the back at the lower end of the frame rod 5, and a large number of U-shaped rods 6 are installed on the lower surface of the frame rod 5 at intervals of one molded frame. A receiving plate 9, 9 for receiving shaft pieces 8, 8 protruding from the vertical and longitudinal positions of the molding frame 7 is provided vertically at the front and back positions of the center of the lower end of each U-shaped rod 6, A pair of cylinders 10 are located at the front and rear positions on the center line of the lower surface of the frame rod 5.
．． 10 is installed vertically on the lower end of the rod of the cylinder.
1 is fixed from the front toward the back, and a number of suppressing protrusions are provided on the lower surface of the pressing rod 11 that can face the upper end opening of the molding frame 7 suspended between the receiving plates 9 of each U-shaped rod 6. 2. A pair of hanging shafts 4b which are extendable and retractable at the front and rear positions of the lower surface of the automatic transfer trolley 3b.
4b is suspended and a hollow underframe 13 is constructed at the lower end from the front to the rear, and the lower horizontal frame 13 is connected between the front and rear sides of the underframe 13.
A pair of arm rods 14, 14 are located on both sides of the inner surface of ', 13'.
' and the lower ends of the arm rods 14, 14' are pivotally connected and protruded, and the upper ends of the arm rods 14.14 and the arm rods 14', 14', which face each other in the front and rear, are connected with each other along a horizontal axis 15.15', A pair of cylinders 16.16 and 16' are provided at the front and back positions on both sides of the underframe 13.
16', and the rod of each cylinder is connected to the horizontal axis 15'.
．． 15' so that the horizontal shafts 15 and 15' can be guided in both directions of the underframe 13, and both side concave portion forming plates 17 of each molding frame 1 suspended and transferred by the first automatic transfer cart 3a. ,17'
The horizontal axis 15.15
The product transfer conveyor 19 is vertically installed at an appropriate distance from the front and back, and a product transfer conveyor 19 is installed at a lower position on one side of the rail 2.

In the figure, reference numeral 20 indicates a product receiving frame, and reference numerals 21 and 21' indicate pallet retaining hooks.

Next, the effects of the present invention will be explained with reference to practical example diagrams.

Each molding frame 1, which has been transferred from the curing room in parallel to one side of the machine frame 1, is moved from the receiving plate 9 of each U-shaped rod 6 of the first automatic transfer trolley 3a to the lower surface of the shaft piece 8. The molds 1 are received while being detoured and raised, and each molding mold 1 is suspended and landed on the upper surface of the receiving frame 20 at one end of the product transfer conveyor 19. After moving in the position direction, the second automatic transfer cart 3b stops moving above the receiving frame 20 that has received each molding frame 7, and lowers the underframe 13. ' engages with the upper ends of the recess forming plates 17 and 17' that are in close contact with the openings on both sides of the molding frame, and at the same time disengages the spring (not shown) that has locked the upper ends of the recess forming plates. -16.16' is horizontal axis 15
．． By guiding 15' outward, the bifurcated claw rod 1B
．． 1B' is also guided outward obliquely downward, and the recess forming plates 17 and 17' are rotated about the pivot at the lower end to open them.

The pallet retaining hooks 21 and 21' that interlock with the recess forming plates 17 and 17' are also simultaneously released outward from the lower surface of the pallet within the molding frame, and both the recess forming plates and the pallet retaining hooks are released. The underframe 13 that has been raised is raised to the second
The automatic transfer cart 3b moves to its original position on the right side of the machine frame 1, and the first automatic transfer cart 3a, which was waiting at a position on the left side of the machine frame 1, moves again to the top surface of each forming frame 1. Each molding frame 7 is suspended and raised, and the concrete product in each molding frame 1 is pushed to the upper surface of the receiving frame 20 using the suppressing protrusion 12 to be removed from the mold, and the molding frame 7 is suspended as it is and transferred to the formwork transfer conveyor. At the same time, each concrete product is transferred by a product transfer conveyor 19.

Therefore, the demolding operation of a large number of molding frames can be performed automatically and simultaneously, making the demolding work highly efficient, and the operator does not need to touch the molding frames by simply operating the operation switch. When pushing concrete products, the molding frame is pushed while suspended, so there is no direct impact on the transfer conveyor, making demolding work more efficient.
It has the remarkable effects mentioned above, such as labor saving.
