In this case, the profile 10 is a part to which the roller assembly R is assembled, out of four sides of a sliding window which is assembled in a rectangular frame shape. For convenience in work, the seating recess 11 of the profile is loaded in such a way as to face upward such that the roller assembly R is mounted downwardly from above.

In the meantime, the conveying part 100 further includes a scanning part 110 which is disposed at an entrance part of the conveying part 100 and has a scanner 111 for scanning a bar code disposed on the conveyed profile 10 so as to automatically recognize the specification of the profile 10 and to output a signal corresponding to a recognized results.

Moreover, the conveying part 100 further includes a control part (not shown) for receiving the signal generated from the scanning part 110 and controlling the components by outputting a processed data so as to automatically carry out the process of assembling the roller assembly R according to a sequential control program.

Referring to FIGS. 2a and 2b, the clamping part 200 serves to fix the conveyed profile 10 at a predetermined position where the assembling process of the roller assembly R is carried out. Here, preferably, the clamping part 200 includes: a cylinder 210 having a rod 211 moving back and forth in a straight line by sequentially receiving pneumatic pressure through two ports; and a pressing member 213 disposed at the front end of the rod 211 for pressing and fixing the side of the profile 10.

In this instance, the clamping part 200 is mounted symmetrically at both sides of the conveyed profile 10 in order to press and fix both sides of the profile 10, but the present invention is not limited to the above. Of course, if the profile 10 can be firmly fixed at a predetermined position, the clamping part 200 may adopt one of various structures, for instance, the structure to press one side and support the other side.

Referring to FIG. 1, the roller supply part 300 serves to locate at least one roller assembly R from a feeder 301 in which a plurality of roller assemblies R are stored. Here, preferably, the roller supply part 300 includes: a pair of first linear modules 310 spaced apart from each other and opposed to each other at one side of the conveying part 100, the first linear modules 310 reciprocating a first conveyance member 311 along a conveyance direction of the conveying part 100 by receiving the driving force of the motor (not shown); a second linear module 320 whose both ends are respectively joined to the first conveyance member 311, the second linear module 320 reciprocating a second conveyance member 321 in a horizontal direction which is orthogonal to the conveyance direction of the conveying part 100; and a grip part 330 mounted on the second conveyance member 321, the grip part 330 grasping the roller assembly R loaded in the feeder 301 in order to convey and supply the roller assembly R into the seating recess 11 of the profile 10.

Referring to FIG. 3b, the grip part 330 will be described in more detail. The third linear module 331 reciprocally moves in the vertical direction because the third conveyance member 332 is mounted integrally with the second conveyance member 321.

Furthermore, a plurality of the fingers 333, three fingers 333 in the preferred embodiment of the present invention, may be spaced apart from each other in a horizontal direction of a holder 330a which is mounted at the lower end of the third linear module 331. The fingers 333 grasp the roller assembly R while selectively operating by receiving pneumatic pressure. The fingers 333 may be air chucks (also called, 'lever air chucks') which have been generally used.

Referring to FIG. 3c, the fingers 333 are mounted at the front end of a rod 335a of a pneumatic cylinder 335 so as to be ascend or descend independently. That is, the fingers 333 grasp the plural roller assemblies R (three in the preferred embodiment of the present invention) from the feeder 301, and then, continuously locate them in the seating recess 22 of the profile 10 at predetermined intervals. Therefore, the present invention can reduce time and the number of work process required for reciprocating the roller supply part 300 in order to grasp the roller assemblies R loaded in the feeder 301, and thus, enhance work efficiency.

Referring to FIGS. 4a to 4c, the joining member assembly part 400 includes: an insertion tube 410 to which a joining member 403 drawn out from a parts feeder 401 is mounted; a cylinder 420 moving back and forth in order to insert and situate the front end of the insertion tube 410, in which the joining member 403 is mounted, into a joining hole of the roller assembly R; and an electronic driver 430 having a driver member 431 rotatably joined inside the insertion tube 410 for joining the joining member 403 onto the profile 10.

In this instance, the joining member 403 mounted in the insertion tube 410 may use pneumatic pressure or the free fall principle according to a height difference, and is supplied through a connection hose. Of course, the present invention is not limited to the above, and may adopt one of various structures if the joining member 403 can be easily mounted inside the insertion tube 410.

The joining member assembly part 400 is adjacent to the parts feeder 401 disposed directly above the conveying part 100, and slidably reciprocates by means of another linear module 440 which reciprocates in an X-axis direction or in a Y-axis direction by receiving a rotational force of the motor.

In addition, in the preferred embodiment of the present invention, the joining member assembly part 400 is one, but the present invention is not limited to the above, and a plurality of joining member assembly parts 400 may be formed in order to join the plural joining members 403 at the same time or sequentially.

Now, an assembling process of the roller assembly machine for window according to the preferred embodiment of the present invention will be described.

First, out of the profiles 10 which form the external frame of the sliding window, the profile 10 on which the roller assembly R is mounted is loaded on the conveying part 100 in such a way that the seating recess 11 faces upward so that the roller assembly R is mounted easily.

The loaded profile 10 starts to be conveyed to one side by the conveying part 100. At the moment that the profile 10 passes a predetermined point, the scanner 111 disposed at one side scans the bar code of the profile 10 in order to automatically recognize the corresponding specification and generate a signal corresponding to the recognized results.

At the same time, the control part receives the signal generated through the scanning part 110 and outputs a processed data, such as the specification of the corresponding profile 10, and a mounted position of the roller assembly R.

Next, the control part controls the clamping part 200 based on the outputted processed data so as to press and fix the side of the profile 10, so that the profile 10 is firmly fixed. In this case, the conveying part 10 stops directly before the clamping part 200 is operated.

When the fixation of the profile 10 is finished, the roller supply part 300 is operated, and then, the roller assemblies R suitable for the specification of the corresponding profile 10 are sequentially located from the feeder 301, in which the roller assemblies R are loaded, into the seating recess 11 of the profile 10 at the predetermined intervals.

In more detail, the grip part 330 of the roller supply part 300 selectively grasps the roller assembly R loaded on the feeder 301 while being reciprocated within a predetermined stroke in the X-axis or Y-axis direction by means of the first and second

linear modules

310 and 320. Here, preferably, the grip part 330 includes a plurality of the fingers 333, for example, three fingers 333, which are operated independently, and can grasp the plural roller assemblies R at once. In this instance, because the number of reciprocations between the feeder 301 and the mounted portion can be reduced, it can reduce a period of time required for conveyance and assembly, and thus, work efficiency is enhanced.

When the roller assemblies R are located in the seating recess 11 of the profile 10, the joining member assembly part 400 joins the joining member 403 mounted inside the insertion tube 410 onto the profile 10 through joining holes (not shown) formed in the roller assemblies R while moving horizontally or vertically, so that the roller assemblies R can be firmly assembled into the seating recess 11 of the profile 10.

When such a series of assembly process is finished, the conveying part 100 is re-operated to convey the profile 10 to one side, and the conveyed profile 10 is assembled and manufactured into a rectangular window frame through the following process.

While the present invention has been particularly shown and described with reference to exemplary embodiment thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
