It is a rear perspective view of a delivery device, and FIG. 3 is an exploded perspective view of the power transmission device of the rollformer of the present invention.

The power transmission device of the present invention roll forming machine shown in the drawings is to rotate the rolling roller of the cassette which is spaced at a predetermined interval to the upper side of the base to bend the plate moving between the rolling rollers, driving means ( 110, driven means 120 driven by the drive means 110, and connecting means 130 for connecting / disconnecting the driving force of the drive means 110 to the driven means 120.

The drive means 110 is composed of a drive motor 112, a drive shaft 114 rotated by the drive motor 112, a reducer 116 to reduce the rotation speed and increase the torque, the drive motor ( The drive shaft 114 which transmits the driving force of the 112 to the reducer 116 forms a clutch 114a at the end for power transmission to the reducer 116 to be installed.

The driven means 120 is the same as the first and second gears 121 and 122 and the first gear 121 are respectively installed and engaged at the end of the plurality of rolling roller (R) shaft (S) located in the cassette (C) It consists of the first and second sprockets 123 and 124 fixed to the shaft, and the chain 125 wound around the sprockets 123 and 124 of the adjacent cassette C to transmit power.

The connecting means 130 is fixed to the drive gear 132 fixed to the output shaft of the reducer 116 and the shaft (S) of any one cassette (C) of the plurality of cassettes (C) of the cassette module (M). It consists of a driven gear 134, an internal gear 136 for connecting / disconnecting the driven gear 134 and the drive gear 132, and a drive unit 138 for moving the internal gear 136, The driving unit 138 is fixed to the arm member 138a whose center is fixed to the base B by the hinge shaft 138c in a state where the internal gear 136 is fixed to one end and the other end of the arm member 138a. It consists of the cylinder 138b which moves the arm member 138a. In addition, a bearing is inserted into the outside of the internal gear 136 so that the internal gear 136 is idle in the state fixed to the arm member 138a.

Hereinafter, the operation of the power transmission device of the present invention roll forming machine having the above configuration.

4A and 4B of the accompanying drawings are plan sectional views showing the action of the power transmission device of the present invention roll forming machine, and FIGS. 5A and 5B are front sectional views showing the action of the power transmitting device of the present invention roll forming machine.

As shown in the figure, the rotational force of the drive motor 112 installed on the base (B) is transmitted to the drive shaft 114 through the belt and pulley so that the drive shaft 114 rotates. The rotational force of the drive shaft 114 is transmitted to the reducer 116 to have a low / high torque rotational force through the output of the reducer 116. Then, the driving force of the driving means 110 is transmitted to the driven means 120 through the connecting means 130 installed with the reducer 116, the shaft (S) of the cassette (C) to which the rolling roller (R) is fixed. Rotate).

That is, the first and second gears 121 and 122 installed at the upper and lower shafts S of the cassette C are engaged with each other, and the first and second gears 121 are fixed to the shaft S to which the first and second gears 121 are fixed. The second sprockets 123 and 124 are fixed to be wound by the sprockets 123 and 124 and the chain 125 of another cassette C adjacent thereto and interlocked with each other.

Meanwhile, the driven gear 134 is fixed to the shaft S to which the sprockets 123 and 124 are fixed to one of the cassettes C among the plurality of cassettes C, and the drive gear 132 to the output shaft of the reduction gear 116. ) Is fixed, and the internal gear 136 connecting the drive gear 132 and the driven gear 134 is disposed outside the drive gear 132 and the driven gear 134 to reduce the speed of the drive means 110 ( 116) The driving roller 132 fixed to the output shaft and the driven gear 134 fixed to the rotating shaft (S) of the cassette (C) of the driven means 120 transmits power to cause the rolling roller (R) to rotate. .

In addition, the front end of the arm member 138a, the center of which is fixed on the base B by the hinge shaft 138c, is hinged and fixed to the internal gear 136, and the rear end thereof is a cylinder 138b fixed to the base B. Fixedly coupled to the working shaft of the cylinder, the internal gear 136 moves on the drive gear 132 as the cylinder 138b is driven, and selectively connects / disconnects the driving force of the drive means 110 to the driven means 120. Done. Here, a bearing is installed outside the internal gear 136 to allow the internal gear 136 to idle in a state of being fixed to the tip of the arm member 138a.

That is, when the cylinder 138b of the connecting means 130 is operated and the working shaft is advanced, the rear end of the arm member 138a is pushed and the arm member 138a is rotated about the hinge shaft 138c to arm the arm member. The tip side of 138a is moved in the opposite direction. Therefore, the internal gear 136 fixed to the front end of the arm member 138a is engaged with the drive gear 132 and the driven gear 134 to transfer the rotational force of the drive gear 132 to the driven gear 134. While being transferred to the driving gear 132 in accordance with the operation of the cylinder 138b is separated from the driven gear 134. As such, the connection member 130 for transmitting the driving force from the driving means 110 to the driven means 120 is disconnected, so that the rolling roller R of the cassette C stops rotating.

In this state, as shown in FIG. 5C, the cassette module M is lifted out and replaced, and then, in the reverse order of the above disconnection, the working shaft of the cylinder 138b is reversed so that the internal gear 136 meshes with the driven gear 134 again. By connecting the driving force of the driving means (110).

The speed reducer 116 is disposed to correspond to the cassette module M. When the cassette module M is extended, the speed reducer 116 is additionally disposed. The rotational force transmission to the reducer 116 to be additionally arranged is achieved through a pair of clutches 114a formed at the end of the pre-installed drive shaft 114 and the drive shaft 114 to the side of the reducer 116 to be additionally installed.

As described above, the power transmission device of the rollformer of the present invention has a selective connection and disconnection of the driving force in transmitting the driving force of the driving means to the cassette, and the connection / disconnection can be easily controlled.

In addition, the power transmission device of the rollformer of the present invention has an effect of excellent expandability in the longitudinal direction by facilitating power transmission to the drive shaft to be additionally arranged.
