Description
A REVERSING DEVICE FOR AN ELONGA~ED SECTION MEMBER
The present invention relates to a reversing device for a section member and more specifical,ly to such a device for turning upside~down a section member that is used, for example, in the manufacturing process of heat insulating sash bars wherein reversing of a sash bar is needed to ~ill grooves on both upper and lower sides of each sash bar with heat insulating material.
It is a known practice to form a heat insulating sash bar with an extruded hollow metal section member having grooves therein which are filled with heat insulating synthetic resin.
In this case, generally -the grooves are provided on both sides of the section member, and after a groove on one side is filled with heat insulating synthetic resin first, the section member is reversed or turned upside-down, then the groove on the other side is filled with heat insulating synthetic resin.
As a device for turning section members upside-down, a reversing device for section members has been proposed which comprises: a rotation shaft horizontalIy supported on a fixed support;
a pair of arm members spaced apart along said shaft facing each other and fixed to said shaft at one end of each of ,.......
i7ti,;c~
said arm me~bers so as to ~orm a ~rame member composed of both of said arm members and said shaft; pairs of pressing devices located on said pair of arm members at positions facing each other for releasably holding elongated section members therebetween; and a means to rotate said rotation shaft for rotating said pair of arm members through an angle of 180 degrees from a first horizontal position to a second horizontal position and in the opposite direction in turn.
This device, however, is not desirable from the lay-out standpoint in which continuity of the transfer line for section members is desired, since the section members are moved for a considerable distance in the lateral direction when they are turned upside-down. Further, there are addi-tional problems brought about by the device since the area or the space occupied by the transfer line is increased, the speed of turning the section members upside-down is limited, and the reversing device itself needs to be big in size, etc.
Therefore, it is an object of the present invention to provide such a reversing device for a section member that does not impair the continuity of the transfer line for section members.
Another object of the present invention is to provide such a reversing device for a section member that allows the wholetransfer line for section members to occupy a small area or space.
B
~762~3 Another object oE the present invention is to provide such a reversing device for a section member that allows the speed of turning section members upside-down to be increased.
A further object of the present invention is to provide such a reversing device for a section member that is small in size.
These and other objects have been attained in a reversing device for section members comprising a pair of wheels located concentrically and spaced mutually apart, each wheel having an aperture at the center thereof through whlch a section member can pass; a fixing means located around the aperture in each wheel to fix the section member to the wheel; at least a pair of driving means to rota-te the pair of wheels in a synchronized manner; and a control means for restricting the anale of rotation of the pair of wheels to 180 degrees.
Since the present invention is constructed as described above, the reversing device for a section member according to -the invention brings the following effec-ts:
~1) Since a section member is located at the center of a pair of wheels, the section member stays on an unchanged ; axis before and after being turned upside-down, which serves to maintain the continuity of the transfer line for the section members.
The present invention relates to a reversing device for a section member and more specifical,ly to such a device for turning upside~down a section member that is used, for example, in the manufacturing process of heat insulating sash bars wherein reversing of a sash bar is needed to ~ill grooves on both upper and lower sides of each sash bar with heat insulating material.

As a device for turning section members upside-down, a reversing device for section members has been proposed which comprises: a rotation shaft horizontalIy supported on a fixed support;
a pair of arm members spaced apart along said shaft facing each other and fixed to said shaft at one end of each of ,.......

Since the present invention is constructed as described above, the reversing device for a section member according to -the invention brings the following effec-ts:
~1) Since a section member is located at the center of a pair of wheels, the section member stays on an unchanged ; axis before and after being turned upside-down, which serves to maintain the continuity of the transfer line for the section members.
(2) Since a section member is reversed or turned upside-down only by the rotation of a pair of wheels, there is no other motion such as a swing during the reversing operation, ~7~2 which helps to minimize the area or space occupied by the whole transfer line for the section members.
(3) Since a section member is reversed or turned upside-down by the rotation of a pair of wheels with the section member being held at the center of the pair of wheels, the reversing speed can be increased as compared with the reversing operation using a swing motion.
(4) Since the major constituent component of the revers-ing device is a pair of rotation wheels, the device can be made smaller in si~e as compared with a swing type reversing device.
The above and o-ther objects and attendant advantages of the present invention will be more readily apparen-t to ' those skilled in the art from a reading of -the following detailed description in conjunction with the accompanying drawinas which show one preferred embodiment of the inven-tion for illustration purpose only, but not for limiting the scope of same in any way.

Fig. 1 is a perspective view of the entire structure of the apparatus for continuously producing sash bars incorporating the invention. A plurali-ty of extruded hollow sash bars 1 are placed on a first carriage 2 one by one at a predetermined time interval by a supplying means not shown. The first carriage 2 includes a movable stand 2b which is moved up and down by a cylinder 2a and is reciprocated transversely of the apparatus by a cylinder 3 and a Eixed stand 2c. When the piston rod oE the cylinder 2a is ex-tended, the sash bars 1 on the Eixed stand 2c are engaged by spacers of the movable stand 2b and are posi-tioned at an equal pitch. Under this condition, when thepiston rod of the cylinder 3 is retracted, the sash bars 1 are moved transversely by one pitch together with the mov-able stand.

With such condition, when the piston rod of the cylinder 3 is extended, the movable stand 2b is returned transversely to its original position for receiving a newly supplied sash bar.
While the sash bars 1 are being moved intermittently on the carriage 2, a heat insulating sheet 15 is inserted into the groove 5 in each of the successive bars 1 by supply rollers 20 and then the opposite ends of the groove ~ ~7~
5 are closed by end caps 6 by a cap attaching device 4.
The sash bars 1 with the grooves 5 closed by the end caps are successively pushed out of the carriage 2 longitudinally of the apparatus by a cylinder 7 and passed below an injec-tion device 8 which injects a solution of heat insulatingsynthetic resin into the grooves 5 in the sash bars 1 one by one.
The sash bars 1 with the heat insulating synthetic resin 9 filled in the grooves 5 are then transferred by feed rollers 38 onto a second carriage 10 which is similar to the first carriage 2 and moved intermittently one pitch by one pitch on the carriage 10 by a movable stand lOb, a fixed stand lOc and cylinders lOa, 11 while allowing the resin solution 9 to solidify during such movement to form a heat insulating synthetic resin body 12.
Thereafter, each of the thus processed bars 1 is pushed out of the second carriage 10 longitudinally of -the apparatus onto a cutter device 14 by a cylinder 13 and center portions of the bottoms of the grooves 5, 5' are cut away by the cutter device 14 [see Fig. 2(e)]. Thereafter, the sash bar 1 is transferred longi-tudinally of the appara-tus by belt device means 18, 19 to a reversing device 17 which holds and turns the sash bar 1 upside-down to face the lower groove 5' of the sash bar upward. The reversed bar 1 is then pushed out of the device 17 longitu-dinally of the apparatus by the next sash bar which is moved toward the device 17 while the bottoms of its grooves are being cut to be again placed on-to the first carriage 2 ~ ~\
~ ~76;~9 where the now upwardly facing groove 5' of the bar 1 is successively lined with the heat insulating sheet 15 and fitted with the end caps 6 and thereafter filled with the heat insulating synthetic resin 12 at the injecting zone in the same manner as the processing of the grooves 5. The sash bars 1 with the heat insulating synthetic resin filled in the grooves 5' are then transferred onto the second carriage 10 and are removed from the downstream end of the second carriage by a removing means not shown.
Fig. 2 shows the sash bars 1 in cross-section in the successive processing steps in the order men-tioned herein-above. The sash bar 1 has the cross-sectional conEiguration as shown in Fig. 2 (A) when ex-truded. In the processing, at first, the sheet 15 is placed onto the bottom of the upper groove 5 of the sash bar 1 as shown in Fig. 2(b), then the opposite ends of the upper groove 5 are closed by end caps
The sash bars 1 with the grooves 5 closed by the end caps are successively pushed out of the carriage 2 longitudinally of the apparatus by a cylinder 7 and passed below an injec-tion device 8 which injects a solution of heat insulatingsynthetic resin into the grooves 5 in the sash bars 1 one by one.
The sash bars 1 with the heat insulating synthetic resin 9 filled in the grooves 5 are then transferred by feed rollers 38 onto a second carriage 10 which is similar to the first carriage 2 and moved intermittently one pitch by one pitch on the carriage 10 by a movable stand lOb, a fixed stand lOc and cylinders lOa, 11 while allowing the resin solution 9 to solidify during such movement to form a heat insulating synthetic resin body 12.

Thereafter, the sash bar 1 is transferred longi-tudinally of the appara-tus by belt device means 18, 19 to a reversing device 17 which holds and turns the sash bar 1 upside-down to face the lower groove 5' of the sash bar upward. The reversed bar 1 is then pushed out of the device 17 longitu-dinally of the apparatus by the next sash bar which is moved toward the device 17 while the bottoms of its grooves are being cut to be again placed on-to the first carriage 2 ~ ~\

The sash bars 1 with the heat insulating synthetic resin filled in the grooves 5' are then transferred onto the second carriage 10 and are removed from the downstream end of the second carriage by a removing means not shown.
Fig. 2 shows the sash bars 1 in cross-section in the successive processing steps in the order men-tioned herein-above. The sash bar 1 has the cross-sectional conEiguration as shown in Fig. 2 (A) when ex-truded. In the processing, at first, the sheet 15 is placed onto the bottom of the upper groove 5 of the sash bar 1 as shown in Fig. 2(b), then the opposite ends of the upper groove 5 are closed by end caps
6 and the sheet 15 is held in position by nipping it between the portion of the cap and the bottom of the groove 5 as shown in Fig. 2(c), the solution of heat insulating syn-thetic resin 9 is injected into the upper groove 5 by theinjection device 8 as shown in Fig. 2(d), the central por-tions of the bottoms of the upper and lower grooves 5, 5' are cut away by the cutter device 14 as shown in Fig. 2(e), the sash bar 1 is turned upside-down to reverse the position of the upper and lower grooves 5, 5' as shown in Fig. 2(f), the sheet 15 is placed onto the bottom of the now upwardly facing groove 5' as shown in Fig. 2(g), the opposite ends of the now upwardly facing groove 5' are closed by end caps ~2~7~29 6 and the sheet 15 is held in position within the groove 5' ' as shown in Fig. 2(h) and the solution of heat insulating synthetic resin 9 is injected into the groove 5' by the injecting device 8 as shown in Fig. 2(i).
Fig. 3 shows a front view of the reversing device as viewed from the cutter device side. The reversing device comprises a pair of wheels 21 (only one is shown in Fig. 3), each wheel having teeth on the outer peripheral surface and an aperture through which a section member is allowed to pass at the center, and the pair of wheels being connected wi-th each other by brackets 23 [see Fig. 4(a)]; pressing rollers 25 and cylinders 24 Eor moving the pressing rollers, the rollers and cylinders being located around the aperture 22 so as to allow a sash bar to be fixed to and set free from the pair of wheels at their center; and a pair of driving gears 26 to support and drive the pair of wheels 21.
The pair of driving gears 26 are connected with each other by a rotation shaft 37 [see Fig. 4(a)], and are driven by a motor 27 through a belt 36. The pair of wheels 21 are supported by and placed on the pair of driving gears 26 and idler gears 28 in such a way that the teeth on the outer peripheral surface of each wheel engage with both the driving gear 26 and the idler gear 28.
Support blocks 35 supporting the rotation shaft 37 of the pair of driving gears work to prevent the movement of the pair of wheels in their axial direction. Since the reversing device is assembled on a base plate 31 which is supported on a foundation 34 through a height adjusting gi'76;~
g mechanism comprlsing a link mechanism 32 and a driving device 33 for the link mechanism, the height of the aper-tures 22 can be adjusted so that the apertures are aligned with the sash bar transfer line.
The function of the reversing device according to the invention is explained hereinafter referring to Fig. 4.
As shown in Figs. 4(a) and 4(b), a sash bar coming out of the cutter device 14, while being held between driving belts 18, 19 and simultaneously having the central portions of the bottoms of the grooves thereof cut away, is transferred toward the right by feed rollers 16 so as to be inserted into the apertures 22 at the center of -the pair of wheels.
As shown in Fig. 4(c), when the forward end of the sash bar blocks the light passage of a photo-electric tube swi-tch 39, cylinder rods of cylinders 24 extend, pressing the rollers 25 onto the sash bar. The sash bar is thus fixed to the pair of wheels at their center.
By the function of a timer, the pair of wheels 21 are then rotated through an angle of 180 degrees, turning the sash bar so that the groove S' faces upwards. The rota-tion angle of the pair of wheels 21 is determined by -the contact of a contact point 30 with a micro switch 29 as shown in Fig. 3. When the reversing of a sash bar is completed, cylinder rods of cylinders 24 retract moving rollers 25 away from the sash bar. The sash bar which has now been set free starts to move toward the right, being pushed by the next sash bar coming out of the cutter device as shown in Fig. 4(e) and Fig. 4(f). The reversed sash bar is then placed on the first carriage 2 again to fill the groove 5' with heat insulating material before the sash bar is completed.
Fig. 3 shows a front view of the reversing device as viewed from the cutter device side. The reversing device comprises a pair of wheels 21 (only one is shown in Fig. 3), each wheel having teeth on the outer peripheral surface and an aperture through which a section member is allowed to pass at the center, and the pair of wheels being connected wi-th each other by brackets 23 [see Fig. 4(a)]; pressing rollers 25 and cylinders 24 Eor moving the pressing rollers, the rollers and cylinders being located around the aperture 22 so as to allow a sash bar to be fixed to and set free from the pair of wheels at their center; and a pair of driving gears 26 to support and drive the pair of wheels 21.
The pair of driving gears 26 are connected with each other by a rotation shaft 37 [see Fig. 4(a)], and are driven by a motor 27 through a belt 36. The pair of wheels 21 are supported by and placed on the pair of driving gears 26 and idler gears 28 in such a way that the teeth on the outer peripheral surface of each wheel engage with both the driving gear 26 and the idler gear 28.
Support blocks 35 supporting the rotation shaft 37 of the pair of driving gears work to prevent the movement of the pair of wheels in their axial direction. Since the reversing device is assembled on a base plate 31 which is supported on a foundation 34 through a height adjusting gi'76;~
g mechanism comprlsing a link mechanism 32 and a driving device 33 for the link mechanism, the height of the aper-tures 22 can be adjusted so that the apertures are aligned with the sash bar transfer line.
The function of the reversing device according to the invention is explained hereinafter referring to Fig. 4.
As shown in Figs. 4(a) and 4(b), a sash bar coming out of the cutter device 14, while being held between driving belts 18, 19 and simultaneously having the central portions of the bottoms of the grooves thereof cut away, is transferred toward the right by feed rollers 16 so as to be inserted into the apertures 22 at the center of -the pair of wheels.
As shown in Fig. 4(c), when the forward end of the sash bar blocks the light passage of a photo-electric tube swi-tch 39, cylinder rods of cylinders 24 extend, pressing the rollers 25 onto the sash bar. The sash bar is thus fixed to the pair of wheels at their center.
By the function of a timer, the pair of wheels 21 are then rotated through an angle of 180 degrees, turning the sash bar so that the groove S' faces upwards. The rota-tion angle of the pair of wheels 21 is determined by -the contact of a contact point 30 with a micro switch 29 as shown in Fig. 3. When the reversing of a sash bar is completed, cylinder rods of cylinders 24 retract moving rollers 25 away from the sash bar. The sash bar which has now been set free starts to move toward the right, being pushed by the next sash bar coming out of the cutter device as shown in Fig. 4(e) and Fig. 4(f). The reversed sash bar is then placed on the first carriage 2 again to fill the groove 5' with heat insulating material before the sash bar is completed.
