摘要： PURPOSE:To shift ready-mixed concrete from one feeder to another and allow the mass production of concrete secondary products without any waste of concrete by providing a flow passage selector valve within a transport tube from one ready-mixed concrete feeder to a product form for receiving the concrete or within a form. CONSTITUTION:The first flow passage selector valves 46a to 46c are provided between feeders 43a to 43c capable of concurrently feeding ready-mixed concrete MC to a plurality of product forms 65a to 65c, and the second flow passage selector valves 50a to 50c. Furthermore, an emergency ready-mixed concrete feeder 45 is provided between the valves 46a to 46c and the feeders 43a to 43c. Also, the selector valve 46b is changed over when the concrete MC cannot be placed continuously into a transport tube led from the feeder 43b to the product form 65b for receiving the concrete MC or into a form, thereby shifting remaining concrete MC to another feeder 43c via the feeder 45. According to this construction, the ready-mixed concrete MC can be continuously placed, thereby allowing the efficient mass production of concrete secondary products.

摘要： PURPOSE:To keep the unwinding and winding points of a hose in a constant spot by providing a nut pivotally mounted on a reel support bed joined in a screwed-in state with a screw shaft approximately paralleling a guide member and a rotation force transmission mechanism to transmit the rotation force of a reel body to the nut. CONSTITUTION:A rotation nut 13 for a ball screw is driven and rotated through a toothed belt pulley 14, a toothed belt 15, and a toothed belt pulley 12 through rotation operation of a reel body 7 rotated when a hose 1 is wound or unwound. The rotation nut 13 for a ball screw is moved along the screw groove of a screw shaft 11 and a reel support bed 8 on which the rotation nut 13 for a ball screw is pivotally mounted is moved along a guide member 9. In this case, since the number of teeth of the toothed belt pulleys 14 and 12 is formed in such a manner that each time the hose 1 is unwound or wound by one full wind, the reel support bed 8 to support a reel body 7 is moved by a distance equivalent to one full wind of the hose 1, the unwinding and winding points of the hose 1 are kept in a constant spot.

摘要： PURPOSE: To prevent the formation of a protrusion on the outer surface of a concrete secondary product by supplying concrete from a concrete input unit into a form via a plug inserting unit and a concrete receiving tube, and then pushing a plug by an elastic member via a plug sending cylinder. CONSTITUTION: The end of a plug inserting unit 12a is connected to a concrete receiving tube 3, a concrete input unit 12b is connected to concrete pressure feeding means, and a plug 7 is inserted into a bearer body 14. Then, a shutter switching cylinder 16 is driven to shut OFF a shutter body 10a, the feeding means and a form 1. Subsequently, a plug sending cylinder 11 is driven to discharge the plug 7 to a predetermined position. The body 10a is operated, the communicating part is exposed to supply ready mixed concrete into the form 1. When a predetermined quantity is placed, the body 10a is again shut OFF, the plug 7 is pushed to press the concrete into the form 1. At this time, the end face of the member 7b becomes flush with the inside surface of the form 1.
