Abstract

PURPOSE:To secure end finishing or the like in a simple structure by attaching a large diametral pulley concentrically with a spool of an endless chain belt equipped with a multiple block member having a line set groove, and stretching a line rotating endless belt so as to become the same level with the block member, in the above captioned device for a mobile fuel pipeline or the like. CONSTITUTION:Endless chain belts 8, 8 are driven by sprockets 3, 3' and 4, 4' and travel a pipeline P held by a block member 7. Simultaneously with this travel, pulleys 1, 1' and 2, 2' larger in diameter than these sprockets 3-4' concentrically installed in shafts 1a, 2a also rotate, traveling endless belts 5, 5'. At this time, the endless belts 5, 5' travel speedier than the chains 8, 8' because of a diametral difference, and comes into contact with the pipeline P, rotating this pipe. In addition, since a little line bend is straightened by pressure of a presser member 9, the pipeline P is surely rotated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is directed to a pipe having a diameter of 6 mm installed as a fuel supply pipe, an air supply pipe, etc. in, for example, automobile fuel pipes or various mechanical devices.
Automatic puff chamfering equipment for uniform finishing work in the circumferential direction on cut surfaces of pipe ends with relatively small diameters of about 20 m/m to 20 m/m or on pipe ends during plastic working, and small diameter piping. This invention relates to a device that horizontally feeds substantially straight pipes, rods, etc. while rotating them, which are used in coating devices and the like for forming coatings on the inner and/or outer circumferential surfaces of.

(Conventional technology) An example of a conventional traversing device of this type is shown in FIG.

Although FIG. 4 shows a cross-feeding device used in an automatic puff chamfering device, it can also be used as the above-mentioned painting device by removing a wire brush member, which will be described later. In FIG. 4, a large number of bridge members (20, 20') each having an outer set groove hooked over a pair of sprockets (21, 22) (21°, 22°) located in the front-rear direction, respectively.
) The upper part of the conveyance mechanism (Ao) is constructed by arranging endless chain belts (25, 25') corresponding to the left and right sides, and the pulleys (23 , 24) Holding the endless belt (26, 26°) stretched across (23', 24°) when the piping (Po) is arranged and set on the side facing the chain belt (25, 25') The conveyor mechanism (Ao) and the endless belt (26,
26'') are respectively connected to a plurality of separately provided external drive motors (not shown), and by changing the number of rotations of each drive motor, the conveyed pipe (Po) itself is rotated. The set piping (Po)
a wire brush member (27) that rotates opposite the end of the
It was configured with.

(Problem to be Solved by the Invention) However, in such conventional technology, chain belts (25, 25°) and endless belts (26°, 26
Since it is only a clamping structure for the pipe (Po) between
Due to insufficient clamping force due to mutual loosening of these belts (25, 26) (25°, 26°), and the presence or absence of some bends in the pipe (P”) itself, the puff chamfering device A slanted pipe (Po) in which a wire brush member (27) is pressed against the end of the pipe (Po) during transportation during finishing work.
The resistance to the rotation of the piping (Po) increases, and the piping (Po) does not rotate smoothly on its axis, making the buffing work at the cut surface or the connection head unreliable. Furthermore, even when used not only as an automatic puff chamfering device but also as a coating device, there are problems such as uneven coating due to unsmooth rotation. Even when used, the drive motor is one for driving the chain belt (25, 25') @ of the transport mechanism (Ao) and one for driving the endless belt (26, 213') for rotating the pipe (Po). It requires a separate motor, and has various problems such as a complicated structure, an enlarged device, an increase in the number of parts, an increase in maintenance man-hours, and a decrease in reliability.

The present invention has been made in view of the above-mentioned problems of the prior art, and in addition to ensuring that the piping itself rotates on its own axis during transportation, the present invention also enables the piping to rotate relative to the rotating surface of the wire brush member in an automatic puff chamfering device. Even if there is some bending, the cut surface or the end surface of the connection head on the piping side can always be positioned in the orthogonal direction, and the cut surface or the end surface of the connection head can be transported in a securely clamped set state. The purpose is to propose a cross-feeding device for small-diameter piping, rods, etc. that can perform buffing work evenly and effectively, has a single drive motor, has a simple structure, and is highly reliable. It is something.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a large number of bridge members having outward setting grooves for setting piping across a pair of sprockets respectively attached to the front and rear shafts. In a cross-feeding device such as a small-diameter pipe, which is equipped with a conveying mechanism in which endless chain belts are provided correspondingly to the left and right, and at least one of the axes in the front-rear direction is configured as a drive shaft, each of the axes is A pulley coaxial with the sprocket and having a larger diameter than the sprocket is attached to the sprocket, and an endless belt is attached to the pulley, and at least the upper part thereof is substantially the same as the link member of the chain belt.
Alternatively, an endless belt is hung on the pulley, and a presser member is provided that is biased downward along the upper side of the endless belt, and at least the presser member The gist is a transverse feeding device such as a small diameter pipe configured so that the endless belt is located at approximately the same level as the piece member of the chain belt in the vicinity, and a sprocket I on the drive shaft side and a sprocket I on the non-drive shaft side. The sprocket is constructed with a large diameter.

(Function) The present invention is configured as described above, and the pulley diameter for the endless belt is larger than the sprocket diameter for the chain/belt, and is provided coaxially, so that the bridge member having the set groove provided in the chain/belt can be In addition to the arrangement of the piping side in the set groove, the cellar 1~ structure, and the vicinity of both ends of the piping are in contact with the endless belt that moves at a higher speed than the feed speed, and a presser foot is provided along the upper side of the endless belt as necessary. Due to the holding effect of the member on the pipe, even if the pipe itself is slightly bent during transport, it can be transported while rotating reliably, and in the automatic puff chamfering device, it is in contact with the rotating surface of the wire brush member, creating a state of high resistance to rotation. Therefore, the puff finishing work on the cut surface or the end surface of the connecting head can be carried evenly.
This can be done reliably, and the coating apparatus that forms the coating can form a uniform coating without unevenness in axial position, thickness, etc.
