Definitions

the present invention relates to an apparatus for cleaning and straightening a tubular article such as a tube forming a support post or a scaffolding tube which is used in building construction or other construction work. More particularly, the invention is concerned with such apparatus for removing concrete off the tubular article and for straightening a bent tubular article.
the present invention aims at the provision of an apparatus for automatially removing concrete off a tubular article and for automatically straightening a bent tubular article simultaneously with the removal of the concrete, which is labour-saving.
an apparatus for for cleaning and straightening a tubular article comprising:
the straightening unit includes a rotatable wheel, and a guide pipe supported on the wheel by a bearing at an eccentric position.
the feed-roller unit includes a rotatable driven roller, and a follower roller normally urged toward the driven roller resilient means such as a spring.
the cleaning unit includes a plurality of drums each having teeth on its peripheral surface and normally urged toward a common central point by resilient means such as a spring.
a straightening unit 2 is supported centrally on a table 1, and first and second feed-roller units 3, 4 are supported on the table 1 upstream of the straightening unit 2, and third and fourth feed-rollers 5, 6 are supported on the table 1 downstream of the straightening unit 2.
These units 2 to 6 are arranged on the table 1 in a straight line.
Designated by A is the path of travel of a tubular article through the apparatus, which path A extends through the respective centres of the straightening unit 2 and feed-roller units 3, 4, 5, 6.
a cleaning unit 7 is disposed, the centre of which is aligned with the path A of the tubular article.
the first, second, third and fourth feed-roller units 3, 4, 5, 6 are all identical in construction.
the number of the feed-roller units is not limited to four as in the illustrated example, it is preferable that a pair of feed-roller units is disposed one on each of the upstream and downstream sides of the straightening unit 2.
Each of the feed-roller units 3, 4, 5, 6 serves to press and crack concrete attached to the outer peripheral surface of a tubular article, such as a single pipe, to move the tubular article along the path A and to support the tubular article.
the straightening unit 2 straightens a bent tubular article by eccentrically swaying the tubular article to a predetermined extent while the article is being supported by the second and third feed-roller units 4, 5.
the cleaning unit 7 removes concrete attached to the other peripheral surface of the tubular article.
each of the feed-roller units 3, 4, 5, 6 includes a pair of support frames 8, 9, a driven roller 10 mounted on a shaft supported between the support frames 8, 9, a top plate 11 supported between the support frames 8, 9, a freely rotatable follower roller 13, and a pair of springs 12, mounted between the top plate 11 and the follower roller 13.
the tubular article is moved along a straight line and sandwiched between the driven roller 10 and the follower roller 13, the latter being normally urged against the tubular article by the resilience of the springs 12.
a motor 14 for driving the feed-roller units and a plurality of sheaves or pulleys 16, 17, 18, 19, 20 are also mounted on the table 1.
An endless belt 22 is trained on the wheel 15 of the motor 14, the sheaves or pulleys 16, 17, 18, 19, 20, 21, and the driven rollers 10; and when the motor 14 is energised each driven roller 10 is rotated in the same direction.
the first feed-roller unit 3 has a guide 23 in which a tubular article to be cleaned and straightened is inserted in the direction of an arow P , and the unit 3 also has a discharge tube 24 through which the tubular article is discharged.
Each of the second and fourth feed-roller units 4, 6 has a discharge tube 24 via which the tubular article is discharged.
the tubular article As a tubular article is inserted through one of the feed-rollers, the tubular article is supported horizontally, and any concrete on the tubular article is squeezed and cracked between the driven roller 10 and the follower roller 13.
the straightening unit 2 includes a pair of support frames 25, fixedly supported on the table 1 one on each of the upstream and downstream sides of the straightening unit 2, a connecting member 26 interconnecting the support frames 25, a bearings 26 is mounted in an opening in each respective support frame 25, a grooved wheel 28 rotatably supported in the bearings 26 via a pair of metal bushes 27, a bearing 29 mounted on the wheel 28 at a position eccentric of the axis a of the wheel 28, and a guide pipe 30 mounted in the bearing 29.
the guide pipe 30 rotates via the bearing 29 relative to the wheel 28.
the axis of the guide pipe 30 is eccentric with respect to the path A of the tubular article and thus, with respect to the axis a of the wheel 28.
the guide pipe 30 has a trumpet-shaped or flared portion 31 so as to forcedly introduce the head of the bent tubular article.
the wheel 28 has in its outer peripheral surface one or more annular grooves 32 for receiving an endless belt 33 for driving the wheel 28.
the endless belt 33 is trained on the wheel 28 and a pulley 35 mounted on the output shaft of the motor 34. Thus, the wheel 28 is rotated by the motor 34.
the tubular article having been inserted into the guide pipe 30 as supported by the second feed-roller unit 4 and/or the third feed-roller unit 5 is disposed in an eccentric position off the path A .
the guide pipe 30 revolves around the axis a of the wheel 28 along an eccentric orbital path to sway the tubular article eccentrically around the axis a .
the distance X between the axis a of the wheel 28 and the axis of the guide pipe 30 is set within the limit of the resiliency of the tubular article, such as a pipe. Therefore, if a tubular article is straight with no bend, the tubular article recovers its original straight form by its own restoration when it is discharged out of the straightening unit 2 after swayed eccentrically. To the contrary, if a tubular article has a bent portion, a restoring force more than the limit of resiliency acts on the bent portion so as to deform the tubular article into a straight form by plastic deformation while the tubular article is swayed eccentrically.
the cleaning unit 7 includes three support frames 36, 37, 38, mounted on the table 1, a pair of bearings 39, 40 mounted respectively on the support frames 36, 38, three drums 42, 43, 44 rotatably mounted between the support frames 36, 37 and between the support frames 37, 38 via respective arms 47, 48, 49, respective shafts 41 and respective bearings 45, and three springs 50, 51, 52 normally urging the respective drums 42, 43, 44 toward the axis of the cleaning unit 7.
the thus cleaned and straightened tubular article may be removed from the fourth feed-roller unit 6, or may be further transferred to an assembly line, such as a length-sorting line or storage line, by an additional feed-roller unit 53 disposed downstream of the table 1.
the driven roller of the feed-roller unit 53 is operatively connected to the roller 10 of the fourth feed-roller unit 6 via an endless belt 55.
concrete attached to a tubular article can be removed by the feed-roller units and the cleaning unit, and if bent the article can be straightened. Further, it is possible to perform both cleaning and straightening simultaneously and automatically, which is labour-saving and high in rate of production.
