Description

AUTOMATIC ASSEMBLY DEVICE FOR CRESCENT BRACKET

The present invention relates to an automatic assembly device for a crescent bracket, and more particularly, to an automatic assembly device for a crescent bracket, which automatically assembles a crescent bracket disposed at one side of a window pane of a sliding window.

In general, a double sliding window is installed on an opening portion of a window or an entrance of a building in order to block out the inside of the building from the outside, thereby blocking out the inside of the building from the outside and opening the window or the entrance of the building.

The double sliding window is configured in such a manner that window panes mounted on a window frame are slidable in right and left directions so as to open and close the window. Such a double sliding window generally includes two window panes or four window panes and is mounted on the window frame. Moreover, the double sliding window includes crescents disposed at overlapped portions of the window panes so as to provide a locking function.

FIG. 1 is a perspective view of a structure of a general double sliding window, and FIG. 2 is a detailed view showing structures of a crescent and a bracket mounted on the double sliding window of FIG. 1.

Referring to FIG. 1, the general double sliding window has a window frame 10 of an approximately rectangular shape. The window frame 10 is mounted on an opening portion of an apartment or a building. The window frame 10 has two to four window panes joined slidably. For instance, a sliding window having three window panes 11 includes one fixed window pane 11a and a pair of sliding window panes 11b joined slidably. In this instance, the fixed window pane 11a is arranged at a middle part of the window frame 10 and is fixed in position as the occasion demands.

Referring to FIG. 2, the sliding window panes 11b which are overlapped with both sides of the fixed window pane 11a when the double sliding window is closed include crescents 21 respectively disposed at one side of each sliding window pane 11b, and the fixed window pane 11a includes brackets 23 disposed at both sides thereof corresponding to the crescents 21. The crescents 21 and the brackets 23 are locking means for selectively opening and closing a pair of the sliding window panes 11b so as to prevent unwanted outside invasions.

Such crescent brackets 23 are assembled to the window pane by hand, for instance, a worker arranges the bracket 23 on one side of the window pane 11 in correspondence with the position of the crescent 21, and then, fixes it one by one using fastening means, such as screw nails.

However, because all of the processes to assemble the crescent brackets 23 are carried out one by one by hand, it causes a decrease of production efficiency of the double sliding window and an increase of a failure rate in the assembling process due to the worker's mistake.

Referring to FIGS. 3 and 4, the automatic assembly device for the crescent bracket according to the present invention includes: a transferring part 100 for transferring a window pane manufacturing profile 1 to one side; a clamping part 200 for fixing the transferred profile 1 at a predetermined position; a bracket feeding part 400 for positioning a crescent bracket 3 on one side of the fixed profile 1; and a fastening member assembling part 500 for fixing the positioned crescent bracket 3 to the profile 1 by the medium of a fastening member 5.

The structure of the automatic assembly device for the crescent bracket according to the present invention will be described in detail as follows.

First, the transferring part 100 is mounted on a main body frame 101 which forms a main body of the device. The transferring part 100 includes a conveyer 103 or a plurality of rollers (the present invention adopts the conveyer) rotating by receiving a driving force of a motor (not shown) and serves to support the bottom of the profile 1 and to transfer the profile 1 to one side.

In this instance, the profile 1 out of the profiles of four sides assembled into a rectangular frame is a part to which the crescent bracket 3 is mounted corresponding to a window pane to which a crescent is mounted. For convenience in work, such a profile 1 is loaded in such a manner that a mounted surface 1a faces upwardly, so that the crescent bracket 3 can be mounted downwardly from the top.

The transferring part 100 includes a scanning part 110 having a scanner 111 for scanning a bar code disposed on the transferred profile 1 so as to automatically recognize the standard of the profile and output a signal corresponding to the recognized result.

Moreover, the transferring part 100 further includes a controlling part 120 for controlling the relevant components by receiving the signal generated in the scanning part and outputting processing data, so as to automatically carry out a process of assembling the crescent bracket 3 according to sequential control programming.

Referring to FIG. 5, the clamping part serves to fix the transferred profile 1 at a predetermined position where the process of mounting the crescent bracket 3 is carried out. Here, preferably, the clamping part 200 includes: a cylinder 210 having a rod 211 which moves straight forward and backward by receiving pneumatic pressure or hydraulic pressure through two ports; and a pressurizing member 220 disposed at the front end of the rod 211 for pressurizing and fixing both sides of the profile 1.

In the present invention, an example of the structure that the clamping part 200 is mounted symmetrically at both sides of the transferred profile 1 to pressurize and fix both sides of the profile 1, but the present invention is not restricted to the above. Of course, if the clamping part 200 can firmly fix the profile 1 at a predetermined position, the present invention may have any structure of the clamping part 200.

Referring to FIG. 6, the automatic assembly device according to the present invention may further include a position setting part 300 disposed at one side of the clamping part 200 for stopping the transferred profile 1 at a predetermined position by blocking the profile 1 transferred by the transferring part 100 while operating earlier than the clamping part 200 with a predetermined time difference between the clamping part 200 and the position setting part 300 or while operating simultaneously with the clamping part 200. In this instance, in the present invention, the case that the position setting part 300 is operated earlier than the clamping part 200 will be described.

The position setting part 300 includes: a cylinder 310 mounted in such a way as to be inclined downwardly at a predetermined angle toward the front end of the profile 1 which is transferred by sequentially receiving pneumatic pressure or hydraulic pressure through the two ports, the cylinder 310 having a rod 311 operating forward and backward; and a blocking member 320 disposed at the front end of the rod 311 and meeting with the front end of the transferred profile 1 when the rod 311 is operated forward so as to stop the profile 1 at the predetermined position.

In this instance, a contact surface 321 of the blocking member 320, which is in contact with the front end of the profile 1, may be made of soft rubber or urethane material, and hence, it can minimize shock applied to the profile 1 when the position setting part 300 is operated.

Referring to FIGS. 3 and 7, the bracket feeding part 400 serves to position any one crescent bracket 3 drawn out from a parts feeder 410, in which a plurality of the crescent brackets 3 are accommodated, at one face of the profile 1 fixed by the clamping part 200 and the position setting part 300. Here, preferably, the bracket feeding part 400 includes: an articulated arm 420 mounted adjacent to an outlet 411 of the parts feeder 410 in which the plural crescent brackets 3 are accommodated; and fingers 430 elevatably mounted at one side of the articulated arm 420 through the medium of a ball screw 431 rotating by receiving the driving force of the motor in order to grasp at least one crescent bracket 3 drawn out from the parts feeder 410 and position the crescent bracket 3 on a mounted surface of the profile 1. In this instance, the fingers 430 are operated in such a way as to be extended and contracted ambilaterally by receiving the driving force of the cylinder or the motor.

For reference, the parts feeder 410 serves to draw out at least one of the plural crescent brackets 3 accommodated therein. In more detail, the parts feeder 410 is a vibrating type parts supplier which arranges and feeds parts in regular direction and position so as to carry out work by a robot (automated equipment) in an automated system, and it is adopted the most in automated systems handling discrete components. The vibrating type parts feeders are divided into a bowl type, a straight type, and a combination type of the bowl type and the straight type. The direction and position of the parts supplied through the parts feeder 410 are detected by a sensor while passing a transferring track, and the parts feeder corrects the direction and position of parts, which are transferred in irregular state, or removes them out of the transferring track. As a method of detecting the direction and position of the parts by the sensor, a method of recognizing the looks of the parts by light transmitted in the sensor is generally utilized.

Referring to FIG. 8a, the fastening member assembling part 500 serves to fix the crescent bracket 3, which is located on one face of the profile 1 by the bracket feeding part 400, on the profile 1 by medium of the fastening member 5. As shown in FIG. 8b, the fastening member assembling part 500 includes: an insertion tube 520 in which at least one fastening member 5 drawn out from another parts feeder 510 accommodating a plurality of the fastening members 5 therein is loaded; a cylinder 530 operating forward and backward in order to insert a front end of the insertion tube 520, in which the fastening member 5 is loaded, into a joining hole 3a of the crescent bracket 3; and an electronic driver 540 having a driver member 541 rotatably joined into the insertion tube 520 so as to fasten the fastening member 5 onto the profile 1.

In this instance, the fastening member 5 loaded in the insertion tube 520 is supplied into the insertion tube 520 through medium of a connection hose using the free fall principle due to a pneumatic pressure difference or a height difference. Of course, the present invention is not restricted to the above, and if the fastening member 5 can be easily loaded into the insertion tube 520, any structure can be applied to the present invention.

The fastening member assembling part 500 is disposed adjacent to the bracket feeding part 400 directly above the transferring part 100, and may be mounted in such a way as to slidably reciprocate by means of a linear guide 550 carrying out a reciprocating motion in an X-axis direction or an Y-axis direction by receiving a rotary force of the motor. The linear guide 550 has been generally used, and hence, detailed descriptions of the structure and operation principle of the linear guide 550 will be omitted.

Now, an assembling process of the automatic assembly device for the crescent bracket according to the present invention will be described.

First, the profile 1 forming the outer frame of a window pane is loaded on the conveyer 103 of the transferring part 100, and in this instance, the mounted surface of the profile 1 faces upward such that the crescent bracket 3 can be easily mounted.

The loaded profile 1 starts to be transferred to one side by the conveyer 103 rotating in one direction by receiving the driving force of the motor (not shown), and the scanner 111 disposed at one side scans the bar code of the profile 1 at the moment the profile 1 passes a predetermined point so as to automatically recognize the corresponding standard and generate a signal corresponding to the recognized result.

The controlling part 120 receives the signal generated through the scanning part 110 and outputs processing data related with the standard of the corresponding profile 1, the mounted position of the crescent bracket 3, and so on.

Next, the controlling part 120 controls the position setting part 300 based on the outputted processing data in order to block the front end of the transferred profile 1, so that the profile 1 is stopped at the predetermined point where the mounting process of the crescent bracket 3 is carried out. At the same time, the controlling part 120 controls the clamping part 200 sequentially in order to pressurize and fix both sides of the profile 1, so that the profile 1 is firmly fixed at the correct position. In this instance, the transferring part 100 is stopped at the same time with the operation of the position setting part 300.

When the position of the profile 1 is fixed, the crescent bracket 3 suitable for the standard of the corresponding profile 1 is supplied from the parts feeder 410, in which the plural crescent brackets 3 are accommodated, through the outlet 411, and then, the fingers 430 elevatably mounted on the articulated arm 420 grasps the supplied crescent bracket 3 and locates it on the mounted surface of the profile 1.

When the crescent bracket 3 is located on the profile 1, the fastening member assembling part 500 fastens the fastening member 5, which is mounted inside the insertion tube 520, onto the profile 1 through the joining hole 3a disposed in the crescent bracket 3 while moving horizontally or vertically, and hence, the crescent bracket 3 is firmly assembled at one side of the profile 1.

When the a series of the assembling process of the crescent bracket 3 is finished, the transferring part 100 is operated again to transfer the profile 1 to one side, and the transferred profile 1 is assembled and manufactured into a rectangular window frame through the next process.

While the present invention has been particularly shown and described with reference to the preferable embodiment thereof, it will be understood by those of ordinary skill in the art that the present invention is not limited to the above embodiment and various changes and modifications may be made therein without departing from the technical idea of the present invention.
