ある。2. Description of the Related Art Conventionally, as this type of rod-shaped air conveying device, for example, as disclosed in Japanese Patent Publication No. 54-34233, a discharge drum rotating at a constant speed is axially mounted between two vertical plates to a pressure feeding position. An air injection port for compressed air that communicates with an air supply source is opened in one of the vertical plates facing the rotationally moved housing groove, and a cylinder head is connected to the other vertical plate, for example, a pipe or tube. The compressed air supplied from the air injection port toward the discharge drum by connecting the transfer pipes such as air jets each tooth profile formed between the accommodation grooves as the discharge drum rotates at a constant speed. The air supply is momentarily blocked only when passing through the mouth, and the tooth profile is continuously passed from immediately after the tooth profile passes through the air injection port to immediately before the tooth profile located next to the tooth profile passes through the air injection port. This empty space is sent into the storage groove. By pressure, the rod-shaped object is pressure-fed from the accommodating groove through the cylinder head into the transfer pipeline, and by ensuring a predetermined discharge pressure at the upstream end of this transfer pipeline, the rod-shaped object is reliably transferred to the receiving device. There is something to be done.

た。However, in such a conventional rod-shaped object air conveying device, from the time when one rod-shaped object is completely fed into the conveying pipe line until the next rod-shaped object is fed. Since the compressed air is supplied almost continuously into each accommodation groove only by instantaneously shutting off the air supply to the accommodation groove, the pressure on the inlet side of the compressed air just supplied from the air injection port into the accommodation groove and the rod shape Even when compared with the outlet side pressure of the compressed air that has moved to the upstream end in the transfer pipeline due to the pumping of the product, the pressure difference between them is small enough to be slightly decreased and the pressure difference is small. Under such a condition, the flow velocity of the compressed air from the accommodation groove to the inside of the transfer pipe is slow, and for example, it is about 2 to 2 as compared with the conventional rod-shaped material.
When we experimented with a rod-shaped object that was about 30% longer, when the discharge pressure of compressed air supplied from the air injection port was doubled,
Along with this, the outlet side pressure of the compressed air at the upstream end in the transfer pipeline also rises, but the pressure difference between them does not become so large, and the long rod-shaped object may become clogged in the cylinder head or the transfer pipeline. is there. Therefore, unless the rotation speed of the discharge drum is reduced by about 60%, long rods cannot be reliably pressure-fed from the accommodation groove into the cylinder head and the conveyance pipeline, resulting in the conveyance of rods. There is a problem that the speed becomes slow and the operation rate is significantly reduced.

間隔が不均一となって進路を妨げるという問題がある。Further, since compressed air is blown to the end portions of the toothed portions projecting from the discharge drum, a turbulent flow of compressed air is generated and the rods are bent in a direction intersecting the pushing direction of the rod-shaped object. Such a force acts, the bent rod-shaped object comes into contact with the inner surface of the housing groove, the inner surface of the cylinder head, etc., and this contact resistance reduces the conveying speed of the rod-shaped object. Since compressed air may be supplied to the two accommodation grooves at the same time, the start timing of pushing the rod-shaped objects in each accommodation groove may vary, which causes a time interval between the rod-shaped objects to be subsequently fed. However, there is a problem that it becomes uneven and hinders the course.

Another object is to make uniform the pushing start timing of the rod-shaped material while preventing the above.

By intermittently supplying air so that the air is blocked longer than the air-shielding time due to the toothed portion formed between the grooves, the compressed air is supplied into the storage groove for a predetermined time and then blocked, and is transferred into the storage groove and conveyed. The pressure on the outlet side of the compressed air remaining in the pipeline decreases, and the pressure difference becomes larger than the pressure on the inlet side of the compressed air supplied from the air injection port into the accommodation groove. The flow velocity of the compressed air flowing into the passage is increased, and a large initial velocity is given to the rod-shaped object in the accommodation groove. Furthermore, a technical means that regulates the discharge pressure of compressed air
According to the above, the intermittent air supply means stops the supply of compressed air.
Even if it is stopped, the rod-shaped object is pressure-fed from the accommodation groove into the transfer pipeline.

The partition wall blocks the air supply to the end position in the accommodation groove where there is no rod-shaped object, and the partition wall communicates with the rod-shaped object in each accommodation groove so that the diameter of the rod-shaped object is approximately equal to or smaller than the diameter of the rod-shaped object. By opening the holes, compressed air is sequentially supplied to only one accommodation groove, and a laminar flow of compressed air flowing only in the same axial direction as the axial direction of the rod-shaped object is generated. It is possible to make uniform the start timing of pushing the rod-shaped material while preventing the turbulent flow of the compressed air from occurring.
