The present invention relates to an apparatus for reversing a stretching member, and in particular, the reversing of the chassis bar rotates the stretching member used in the manufacturing process of the insulating chassis bar, which is required to fill the insulating material in the upper and lower grooves of each chassis bar, up and down. Relates to a device.

It is well known to form a heat insulating chassis with an extruded hollow metal member having grooves filled with a heat insulating synthetic resin.

In this case, grooves are generally installed on both sides of the stretching member, and first, the insulating synthetic resin is filled in one groove, and then the insulating member is filled in the other groove as the stretching member is reversed or up and down.

However, in the known method, since the reversal of the stretching member is performed manually, the production rate is lowered.

Therefore, an object of the present invention is to improve the efficiency by providing a device for automatically reversing the stretching member instead of the manual.

The reversing device is a pair of arms which are positioned at intervals along the axis and facing each other to form a three-sided rectangle composed of a rotating shaft horizontally supported on the fixed support plate and the arm member and the shaft. A pair of pressure devices positioned on the pair of arm members at positions facing each other for fixing the member and the stretching member therebetween, and the arm member from the first horizontal position to the second horizontal position and in the opposite direction; Means for rotating the rotating shaft to rotate 180 degrees.

The reversing apparatus for the stretching member according to the present invention configured as described above can obtain the following effects.

(1) The stretching member is automatically fixed between the pair of arm members, and then automatically rotates the pair of arm members 180 ° around the rotation axis, thereby reversing accurately without manual operation.

(2) Since the pair of arm members rotate 180 ° around the axis of rotation, the pair of arm members can rotate to their original positions without interfering with other stretching members supplied to the reversing apparatus during reverse operation, thereby reversing the stretching members. It can shorten the time required to improve the efficiency.

The above objects of the present invention will become more apparent as the drawings describe it.

1 is a perspective view showing the overall structure of a continuous production apparatus for a chassis bar according to the present invention. A plurality of extruded hollow chassis bars 1 are placed on the first reciprocating bands 2 one by one at predetermined time intervals by a feeder (not shown in the figure). The first reciprocating band 2 includes a movable stand 2b that moves up and down by the cylinder 2a and reciprocates to the side of the apparatus by the cylinder 3, and a fixed stand 2c. When the piston rod of the cylinder 2a is extended, the chassis bar 1 on the fixed stand 2c is engaged with the spacer of the movable stand 2b and positioned at the same pitch. In this state, when the piston rod of the cylinder 3 is retracted, the chassis bar 1 moves laterally by one pitch with the movable stand. When the piston rod of the cylinder 2a is retracted, the chassis bar 1 is separated from the spacer of the movable stand and placed on the fixed stand. In this state, when the piston rod of the cylinder 3 is extended, the movable stand 2b returns to its original position to receive the newly supplied chassis bar.

As the chassis bar 1 moves intermittently in the carriage 2, a heat insulating plate 15 is inserted into each groove 5 of the continuous bar 1 by the feed rollers 20 and against each other of the grooves 5. The end is closed with the end cap 6 by the cap attaching device 4. The chassis bar 1 with the groove 5 sealed by the multi-cap is pushed continuously from the carriage 2 in the longitudinal direction by the cylinder 7, one by one into the groove 5 of the chassis bar 1. It passes through the injection apparatus 8 which injects the adiabatic synthetic resin solution.

The chassis bar 1 filled with the insulating synthetic resin 9 in the groove 5 is moved to the second reciprocating band 10 by a transfer roller 38, and the second reciprocating band 10 is the first reciprocating band. It is similar to the base 2 and is moved one pitch from the king, the base 10 by the movable stand 10b, the fixed stand 10c, and the cylinder 10a, and to form the movement interruption heat synthetic resin 12. The synthetic resin solution 9 can be solidified.

Subsequently, each of the two chassis bars 1 is pushed in the longitudinal direction from the second reciprocating band 10 to the cutting device 16 by two cylinders 13 and 14 at the same time to the grooves 5 and 5 '. The central portion of the bottom of the cutting edge is cut by the cutting device 16 (see also second (e)). Next, the drive roller of the chassis bar 10 (not shown) lengths the reversing device 17. Direction and the reversing device 17 fixes the chassis bar and flips the chassis bar so that the lower groove 5 'of the chassis bar 1 faces upward. The reversed chassis bar is pushed longitudinally from the reversing device 17 by the two cylinders 18 and 19 and put back on the first reciprocating band 2 by the drive roller 30. In the first reciprocating band, the newly upwardly grooved groove 5 'of the chassis bar 1 is continuously embedded by the insulation plate 15 and fitted into the end cap 6 and then in the injection zone. Filled with adiabatic synthetic resin 12 in the same manner as the process. The chassis bar 1 filled with the insulating synthetic resin in the groove 5 'is transferred to the second reciprocating band 10 and removed from the rear of the second reciprocating band by a removing means (not shown).

In operation, the insulation plate 15 is initially placed at the bottom of the upper groove 5 of the chassis bar 1 as shown in FIG. 2 (b), and then both ends of the upper groove 5 are connected to the end cap 6. It is sealed in place, and fixed in place by tightly tightening the insulation plate between the cap portion and the bottom of the groove 5 as shown in FIG. (8) is injected into the upper groove (5), the central portion of the bottom of the upper, lower grooves (5) (5 ') is crushed by the cutting device 16 as shown in the second (e), and the chassis bar ( 1) is rotated up and down to reverse the position of the upper and lower grooves 5 and 5 'as shown in FIG. 2 (f), and the groove 5 in which the insulation plate 15 is newly upward as shown in FIG. 2 (g). Is inserted into the bottom of '), both ends of the newly upwardly grooved groove 5' as shown in FIG. 2 (h) are sealed by the end cap 6 and the insulation plate 15 is in position in the groove 5 '. Fixed to the solution of the insulating synthetic resin (9) as shown in the second (i) By an injection device (8) is emitted to the groove (5 ').
