る。2. Description of the Related Art With respect to a lightweight bottle called a PET bottle, etc., each process of washing, sterilizing, filling, sealing with a lid depends on the structure of a device for performing each process and a size of a factory where the device is arranged. From the same plane in many cases. That is, the lightweight bottle must be transported up and down to perform these steps.
In the upward and downward transport of the lightweight bottle, there has been a problem that the neck flange is inclinedly engaged with the transport rail, or the shoulder of the lightweight bottle is pressed against the transport rail, so that the transport is delayed. In particular, when the transport of a lightweight bottle is stopped during ascending transport, the shoulder of the lightweight bottle that has been transported at high speed from behind collides with the body of the suspended lightweight bottle, and the lightweight bottle is damaged. There was a problem. Also, when the lightweight bottle is stopped during the downward transport, the body of the lightweight bottle transported from behind at a high speed collides with the shoulder of the suspended lightweight bottle, and the lightweight bottle is damaged. There was a problem. In order to solve the problem related to the conveyance, Japanese Patent Laid-Open No.
JP-A-341423 proposes a pneumatic conveyor for conveying a tilted trajectory of a lightweight bottle. In this device, in a configuration in which a lightweight bottle having a neck flange at the neck portion is transported by hooking the neck flange on a transport rail and blowing gas, the attitude control air jet supply chamber disposed along the inclined trajectory transport path. The ejected air jet exerts a pressing force in the upward direction of the inclined locus so that the lightweight bottle is substantially perpendicular to the inclined locus transport path.

In the device disclosed in Japanese Patent No. 41423, it is possible to apply a pressing force in the upward direction of the inclined trajectory by the air jet, but it is necessary to stably make the lightweight bottle substantially perpendicular to the inclined trajectory conveying path. It is very difficult in practice to control the pressing force. In particular, when transporting a lightweight bottle that has been transported in the horizontal direction in the upward direction,
At the boundary portion, the vertical lightweight bottle must be steeply inclined, and there remains a problem that the bottoms of the adjacent lightweight bottles are crashed and damaged.

開口３０が設けられている。BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a bottle conveying apparatus according to an embodiment of the present invention. The bottle transport device 1
As shown in FIGS. 1 and 2, a synthetic resin bottle B, which is supported by the gantry 4 and has a neck flange F at the neck, is hooked on the ascending conveying rail 10, and the bottle B
A gas is blown from the duct 12 to the top of the bottle B, and the bottle B is conveyed by bringing the bottom surface of the bottle B into contact with the conveyor belt 14. The transport speed is about 32 meters / minute. The transport rail 10 is a pair of parallel rails facing each other at a slightly wider interval than the thickness of the neck of the bottle B,
Is attached to the bottom surface 18. The duct 12 has a substantially square cross section and is always at a positive pressure. Duct 12
Has a gap 20 extending in the longitudinal direction for mounting the transfer rail 10, and a transfer gas guide 22 having a rectangular cross section is mounted so as to cover the gap 20. Duct 1 is provided on both sides of carrier gas guide 22.
A plurality of injection openings 30 are provided for blowing the gas in 2 to a portion above the neck flange F of the bottle B along the transport direction.

して円滑な搬送を行う。A guide plate 34 is disposed at an intermediate position between the conveyor rail 10 and the conveyor belt 14 to prevent the bottle B from being swayed during conveyance. The conveyor belt 14 is driven by a drive pulley 50 and a guide pulley 52, and the drive pulley 50 is connected to a motor 54 by a belt. The conveyor belt 14 is positioned so as to contact the bottom surface of the bottle B and lift the neck flange F of the bottle B from the transport rail 10 by about 1 to 2 mm. Further, it is desirable that the conveyor belt 14 is made of a material such as polyester so that the surface of the bottle B is not damaged and the bottle B does not slip when it comes into contact with the bottom surface of the bottle B. The surface of the conveyor belt 14 may be provided with irregularities to prevent slippage. The running speed of the conveyor belt 14 is about 38 meters / minute, which is higher than the bottle conveying speed. The portion above the neck flange F of the bottle B is subjected to the force of running while being blown with gas, while the lower portion of the bottle B tends to be delayed in conveyance, particularly at a position where the conveyance path starts to rise and incline. The tendency becomes remarkable. In this state, it is difficult to smoothly transport the bottle B at a right angle to the transport rail 10 by making the traveling speed of the conveyor belt 14 higher than the transport speed because the bottle B is not at a right angle to the transport rail 10. Carry out.

る。When the transport rail 10 is inclined downward, the traveling speed of the conveyor belt 14 is set lower than the transport speed,
The bottle B is set to be substantially perpendicular to the transport rail 10.
