Description
:~222134 A REVERSING DEVICE FOR ELONGATED SECTION MEMBERS
The present invention relates to a reversing device for section members and more specifically to such a device for turning section members upside-down that is used, for example, in the manufacturing process of heat insulating sash bars wherein reversing of sash bars is needed to fill 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 insulat-ing 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 first filled with heat insùlating synthetic resin, the section member is reversed or turned upside-down, and the groove on the other side is then filled with heat insulating synthetic resin.
In the prior art method, however, the reversing of the section members has been carried out manually and, therefore, production efficiency was low.
Therefore, it is an object of the present invention to provide a device for reversing section members automati-cally instead of manually, thus allowing an improvement in efficiency.

. }, ~ZZZ134 Fig. 1 is a perspective view of the entire structure of the apparatus for continuously producing sash bars incorporating the invention. A plurality 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 '0 and a fixed stand 2c. When the piston rod of the cylinder 2a is extended, the sash bars 1 on the fixed stand 2c are engaged by spacers of the movable stand 2b and are posi-tioned at an equal pitch. Under this condition, when the piston rod of the cylinder 3 is retracted, the sash bars 1 are moved transversely by one pitch together with the mov-able stand. When the piston rod of the cylinder 2a is retracted, the sash bars 1 are out of the spacers of the movable stand and are placed on the fixed stand 2c. 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 anewly supplied -ash bar.
While the sash bars 1 are being ~oved intermittently on the ca~iage 2, a heat insulat.ing sheet 15 is inserted into the groove 5 in each of the successive bars 1. by supply ~ollers 20 and then the oppos.ite ends of the groove ', are closed by end caps 6 by a cap attaching device 4.
~ Th_ sash bars 1 with the grooves 5 closed by the end caps :: are successively pushed out of the carriage 2 lon~itudinally , 1222~34 of the apparatus by a cylinder 7 and passed below an injec-tion device 8 which injects a solution of heat insulating synthetic 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 are 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 two of the thus processed bars 1 are at one time simultaneously pushed out of the second carriage 10 longitudinally of the apparatus onto a cutter device 16 by two cylinders 13, 14 and central portions of the bottoms of the grooves 5, 5' are cut away by the cutter device 16 [see Fig. 2(e)l. Thereafter, the sash bars 1 are transferred longitudinally of the apparatus by driving rollers not shown O to a reversing device 17 which holds and turns the sash bars 1 upside-down to face the lower grooves 5' of the sash bars upward. The reversed bars are then pushed out of the device 17 longitudinally of the apparatus by two cylinders 18, 19 and by driving rollers 30 to be again placed onto the first carriage 2 where the now upwardly facing arooves 5' of the bars 1 are successivley 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 ~22Z~34 injecting zone in the same manner as the processing of the grooves S. The sash bars 1 with the heat insulating syn-thetic resin filled in the grooves 5' are then transferred onto the second carriage 10 and are removed from the down-S stream end of the second carriage by a removing means notshown.
Fig. 2 shows the sash bars 1 in cross-section in the successive processing steps in the order mentioned herein-above. The sash bar 1 has the cross-sectional configura-tion as shown in Fig. 2(a) when extruded. In the process-ing, initially, the sheet 15 is placed onto the bottom of the upper groove 5 of the sash bar 1 as shown in Fiq. 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 insu-lating synthetic resin 9 is injected into the upper groove 5 by the injection device 8 as shown in Fig. 2(d), the central portions of the bottoms of the upper and lower grooves 5, 5' are cut away by the cutter device 16 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 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 ~.2ZZ~34 , injected into the groove 5' by the injecting device 8 as shown in Fig. 2(i).
Fig. 3 shows a perspective view vf the reversing device comprising: a rotation shaft 21 horizontally supported on a fixed support 38; a pair of arm members 25, 26 spaced apart along the shaft 21 facing each other and fixed to the shaft 21 at an end o~ each arm member 25, 26 so as to form a U-shaped configuration composed in the shown embodiment of the arm members 25, 26 and the shaft 21; pairs of pressplates 35 facing each other and fixed to piston rods of cylinders 27, Z8 which are located horizontally on the pair of arm members 25, 26, respectively; and a pinion 24 fixed to the rotation shaft 21, and a cylinder 22, the piston rod of which has a rack 23 engaging with the pinion 24 thereon.
In Fig. 3, the rotation shaft 21 is rotated through an angle of 180 degrees by vertically reciprocating cylinder 22 through the rack 23 and pinion 24 engagement.
The piston rod of each cylinder 27, 28 located on each arm member 25, 26 extends through each arm member and is provided with the press-plate 35 at the end of each piston rod.
Although not shown in the drawing, each cylinder 22, 27, 28 is operated automatically and in a mutually related manner so that sash bars can be turned upside-down as the sash bars are supplied into the device as explained below.
In Fig 3., 29, 30 are driving rollers and 31, 32, 33, 34 are guide rollers. The driving rollers 29 introduce ~,r sash bars transferred from the cutter device 16 into the lZ2Z~34 reversing device with the help of guide rollers 31, 32.
The sash bars introduced into the reversing device are stopped at appropriate positions explained below by brake means (not shown) operated b~ limit switches ~not shown).
The driving rollers 30 transfer reversed sash bars to the next station with the help of guide rollers 33, 34.
The top portion of driving rollers 29, 30 and guide rollers 34 is cut into a conical shape so as not to interfere with the reversing movement of the sash bars.
The operation of the reversing device is explained hereinafter. The piston rod of the cylinder 22 is retracted moving the rack 23 downward, which rotates the shaft 21 counter-clockwise through an angle of 180 degrees moving arm members 25, 26 to a leftward position from their original position in Fig. 3.
Sash bars 1 transferred from the cutter device 16 are introduced into the reversing device by driving rollers 29 and guide rollers 31, 32 and are stopped by brake means mentioned above at locations suitable for being held between the arm members. Then the piston rod of the cylinder 22 is extended moving rack 23 upward, which rotates arm members 25, 26 clockwise through an angle of 180 degrees to their original position, where the arm members are stopped to hold sash bars 1 longitudinally at both of their ends.
As is apparent from Fig. 4, the upper grooves 5 of the sash bars have been filled with heat insulating synthetic resin 12. Piston rods of cylinders 27, 28 are extended to hold ., sash bars 1 longitudinally between the press-plates 35.

Next, the piston rods of the cylinders 27, 28 are retracted to set free the sash bars, and leave them on guide rollers 33. The piston rod of the cylinder 22 is extended again moving the rack 23 upward, which rotates the arm members clockwise. Then, the driving rollers 30 are rotated to move the sash bars to the next station, namely, onto the first carriage 2. At this time, as is shown by the phantom line in Fig. 4, heat insu-lating synthetic resin 12 is located at the bottom of the sash bar 1 with the ~roove 5' located at the top.
Fig. 5 shows another embodiment of the invention, which is suitable for reversing relatively long sash bars.
Arm members 25, 26 are connected with each other by re-inforcing members 36. Cylinders 37 are provided on the reinforcing members so that each sash bar held by the cylinders 27, 28 in the longitudinal direction are addi-tionally held by a pair of cylinders 37 in the lateraldirection, which allows the sash bars to be held more securely.
