Description

DESCRIPTION

DELAY LINE WITH TRIPLE DRILLING AND BORING GROUP FOR PROCESSING PVC SECTIONS

This invention relates to a delay line with triple drilling and boring group where the sections processed in 4-corner welding machines undergo triple drilling and boring during cooling before proceeding with CNC corner cleaning machine.

Today, hot burrs are formed on joining corners of PVC sections processed in 4-corner welding machines. The PVC sections should be processed in CNC corner cleaning machines to remove these burrs. However, the PVC sections should undergo cooling before being processed in CNC corner cleaning machine as their joining corners are hot. For this purpose the PVC sections are delayed for some time between the 4- corner welding machines and CNC corner cleaning machines. During such delay, time losses take place, which prolongs production times and increases the costs. Furthermore, triple drilling and boring processes are carried out on the PVC section on a separate machine before the 4-corner welding machine. Therefore, these processes result in additional time and labor consumption.

By virtue of the product hereunder, the section processed in the 4-corner welding machine is conveyed to the CNC corner cleaning machine automatically. The burrs on the PVC sections can properly be removed by the CNC machines as the PVC sections will reach to sufficiently low temperature during this conveyance. By virtue of the product hereunder, the PVC sections undergo triple drilling and boring after the 4- corner welding machine before proceeding with the CNC corner cleaning machine. By this virtue, the sections are processed during the period of cooling of the sections, thereby saving the time for cooling. The product hereunder reduces the production times and production costs as the sections undergo triple drilling and boring during cooling.

(8) positioned on the upper part of the main body (1) by means of the belt gears (5) on the rotating shaft (6). The conveyors convey the sections (9), processed in the 4- corner welding machines without being damaged. As a certain time will elapse while conveying the PVC sections (9), the sections (9) coming from the 4-comer welding machines at a certain temperature are cooled. By this virtue, they are allowed to enter the CNC corner cleaning machines, the next step, at appropriate temperature. To avoid waste of time for conveying the sections, a triple drilling and boring group (10) is provided at side middle part of the main body (1). The triple drilling and boring group is provided with a carrier plate (11) and a support plate (12), positioned perpendicular to the carrier plate (11). The carrier plate (11) is fixed on the main body (1) by means of welding, bolts, etc., to ensure fixation of the triple drilling and boring group (10) on the main body (1).The triple drilling section (13) is located under the carrier plate (11). The triple drilling section (13) is equipped with a triple drilling motor (14), on which triple drilling unit (15) and triple drilling tips (16) are located. At the bottom of the triple drilling section (13), a triple drilling vertical motion roller (18) is located on the guide rollers (17) to move the triple drilling motor (14). Motion of the triple drilling vertical motion roller (18) is controlled by a hydraulically operated triple drilling speed control roller (19). Triple drilling process is possible on sections (9) with different sizes and dimensions by virtue of the triple drilling vertical motion roller (18) and speed control roller (19). A Section holding plate (20) is located in front of the support plate (12) on the triple drilling and boring group (10). The triple drilling chamfer (21) is located at the middle of the section holding plate (20). There is also a boring chamfer (22) on the support plate (12), located just over the section holding plate. The upper pressing roller (23) is located at the top of the support plate (12). The upper pressing roller is connected to the support plate (12) via the roller holder (24). The upper pressing plate (25) is located at the end of the upper pressing roller (23). There are upper pressing guide rollers (26) located at the side of the upper pressing roller (23). The upper pressing roller (23). Moves the upper pressing plate (25) along the vertical axis by means of these upper pressing guide rollers (26). There is an upper coupling apparatus (27) located at the upper part of the support plate (12) fixed on the roller holder (24) at the middle by means of bolts, etc. The upper coupling apparatus (27) is moved by the upper coupling motion rollers (28) located at the rear of the support plate. The upper coupling apparatus (27) rotates around the point of fixation to the roller holder (24). There is a boring section (29) at the rear of the support plate (12). The boring section is equipped with a boring motor (30) positioned at the rear of the support plate (12). A boring tip (31) is placed at the end of boring motor (30). There is a right - left motion roller (32) placed parallel to the support plate (12) at the bottom of the boring motor (30). There is also a forward - backward motion roller (33) placed perpendicular to the support plate (12) again at the bottom of the boring motor (30). Upward and backward motion of the boring motor (30) is provided by the upward - downward motion roller (34) located at the bottom of the boring motor (30). The boring section speed control roller (35) at the side of the upward - downward motion roller (34) controls the motion of the boring motor (30). Left - right motion roller (32), forward - backward motion roller (33), upward - downward motion roller (34) and boring section speed control roller (35) are located at the bottom of the boring motor (30) of the boring section (29). The rollers (32, 33, 34 and 35) in the boring section (29)moves the boring tip (31) right - left, forward - backward and downward - upward depending on the size and type of the section to be processed, to allow boring on section (9) with different sizes. The boring tip (31) moves through the boring chamfer (22) on the support plate (12). In the product hereunder, the setting drive motor (36) is located between the two leftmost conveyors out of the conveyors (9) placed on the main body (1 ). This drive motor (36) drives the setting belt (38) by means of the drive gear (37) on it. One end of the setting belt is connected to the idle gear (39) just over the carrier plate (11). There is an encoder (40) behind the idle gear (39). This encoder (40) measures the motion of the idle gear (39) and transmits data to the PLC controlling the product hereunder. The product hereunder is provided with a setting group (41) placed in front of the setting drive motor (36). The setting group (41) moves forward and backward by means of the setting drive motor (36). The setting group (41) has a setting man body (42). There is a setting plate (43) in front of this main body (42). There is a setting vertical motion piston (44) under this setting plate (43). The setting plate (43) moves downward and upward along the vertical axis by means of this piston (44). The lower coupling apparatus (45) is located behind the setting plate (43). The lower coupling motion piston (46) is located under the lower coupling apparatus (45). The lower coupling motion piston (46)moves the lower coupling apparatus (45). As the lower coupling apparatus (45)is connected to the setting main body (42) by means of a pin, it forms a circular motion. There is a car (47) at both sides of the setting main body (42). By means of these cars (47), the setting main body (42), and therefore the setting plate (43) move forward and backward on the rails (48). As the size and type of the section coming from the 4-corner welding machine is known by the PLC system, controlling the product hereunder, the setting drive motor (36) is run by means of this PLC system and moves the setting plate (43) on the rails (48), and stops it at the most appropriate point depending on the size and type of the section (9). The distance moved by the setting plate (43) is measured by the encoder (40) behind the idle gear (39). Then, the setting plate (43) is lifted up by the setting vertical motion piston (44). When the sections (9) moving on the conveyors (8) approaches the setting plate (43), they are detected by the sensors and the conveyors (8) stops. The section (9), becoming stationary, is fixed by virtue of tensile circular motion of the lower coupling apparatus (45) and upper coupling apparatus (27), so that its part to be processed is positioned on the holding plate (20). Then, the triple drilling tips (16) perform triple drilling on the section (9), passing through the triple drilling chamfer (21) as driven by the triple drilling motor (14). Motion of the triple drilling motor (14), and therefore the triple drilling tips (16) along the vertical axis is provided by the triple drilling motion roller (18) and triple drilling speed control roller (19) located in the triple drilling section (13). Similarly, the boring tip passes through the boring chamfer (22) on the support table (12) as driven by the boring motor (30), and performs boring on the section (9). During the boring process, downward - upward, right - left and forward - backward motions of the boring tip (31) depending on the length and type of the section (9) are provided by the motion rollers (32, 33 and 34) and speed control roller (35) in the boring section (29). After triple drilling and boring processes are completed on the section (9) at the triple drilling and boring group (10), the setting plate (43) moves downward and conveys the section (9) to the CNC corner cleaning machine. As mass production is involved in the product hereunder, the setting plate (43) again moves on the rails (48) and gets the most suitable position depending on the size and type of the next section (9) to process the next section (9). There are holding brushes (49) at the point of rotation of the conveyor in the front. These holding brushes (49) avoids small sections (9) from moving downward and enter between the machines during conveyance. By virtue of the product hereunder, time losses are avoided as triple drilling and boring process is carried out during the period of cooling of the sections (9), thereby increasing the production speed and production capacity.
