The present invention relates to a bead removal device for heat fusion device of window frame aggregate, and in particular, when fabricating a plurality of sets of plastic chassis for window frame to heat-bond the cut surfaces of the respective materials, the material is placed up and down on the plastic joint. Clamping is carried out to form a thermal bond between materials using a heating plate, and after cooling, beads formed on the joint surface can be neatly removed using a plane cutter, a vertical cutter and a rail groove cutter. After the flat cutter of the tub scrapes and removes the beads formed on the upper and lower surfaces of the plurality of materials at the same time, the vertical bead removing device operates to remove the beads generated at the edges of the joint at the time of the falling and the rising, so that the processed surface is neatly processed. Cutter strongly pushes bead formed in each rail groove of material from outside to inside By removing the beads of the haptic surface and joining them to the inner surface of the rail groove, it serves to reinforce the joint surface at the same time as the removal of the bead, not only to maintain a more solid joint but also to improve productivity and workability. The present invention relates to a bead removing device for a thermal welding device of a window frame aggregate.

In general, in the case of manufacturing the window frame using the aggregates for the window frame of the synthetic resin material, the first application of the patent application Nos. 1998-3475 and 2003-29504, such as 'thermal fusion device of the window frame aggregate' As disclosed, the end is provided with a plurality of aggregates for window frames cut at an angle (about 45 °), and it is placed on each pallet of the thermal welding apparatus in turn, according to the control operation of the apparatus. Clamping work of each aggregate and melting, fusion, and bonding of these adhesive surfaces are made in order to manufacture window frames of a certain standard.

In manufacturing the window frame of the synthetic resin material using the heat welding device, the joint portion of each aggregate made of the synthetic resin material during the window frame manufacturing process is pressed for a predetermined time in the molten state by the heating and pressing operation of each clamp assembly on the welding machine Since fusion splicing is made, beads of a shape protruding outward from each corner joint of the aggregate are generated.

As such, when the bead-produced window frame is used as it is, the quality of the window frame may be deteriorated due to aesthetic problems, and in the installation and use of the window frame, it may cause functional problems. There was concern.

Therefore, in the manufacturing work of the window frame using the aggregates for the window frame of the synthetic resin material, it is necessary to remove the beads generated at the joint portion of each aggregate,

In the conventional case, since the window frame, which has been fusion-bonded, has been manually transported and aligned by the worker manually through the heat fusion devices as described above, the bead finishing operation for each joint is removed. In addition, the work is very cumbersome, and the manpower and time required for the work are wasted unnecessarily, resulting in a significant drop in workability and productivity due to window frame manufacturing work.

In addition, due to the above problems, the manufacturing cost of the window frame is increased, causing a problem that the economic burden on the construction personnel or general consumers who purchase it.

In addition, the conventional heat fusion splicer for window frame aggregate as described above is mostly made of one or two sets of clamping work and the heat fusion portion for fusion of the aggregate, as well as fusion assembling work of the window frame using the same is very cumbersome, work Due to the large number of processes, there was a problem that the workability and productivity were greatly reduced by increasing the delay and the defective rate of working time, which has been a major factor in increasing the supply cost of products.

This is because when the height adjustment of the clamping plate according to the height dimension of the window frame aggregate is made of the bolt assembly type, the height adjustment is necessary because the clamping plate must be arbitrarily adjusted by the operator while loosening and tightening the bolt with a separate tool when changing the dimensions. In addition to the time it takes a considerable time, there was a very difficult and cumbersome work.

In addition, the hot plate that melts the window frame aggregate during heat fusion welding is allowed to enter and melt between the attachment surface of the window frame aggregate, when the length of the window frame aggregate is longer or shorter than the set dimension, the molten portion of the window frame aggregate is not constant, the joint surface There was a problem that has a great effect on the melt bonding strength of.

And the height adjustment of the clamping plate of the window frame aggregate has been tried in some techniques consisting of hydraulic, pneumatic cylinder,

In this case, since the lifting support plate of the upper portion is composed of only one stage on the lower fixing plate, there is a limiting element that is unable to receive and bond the window frame aggregate having a high height or thickness in the end due to the limitation of the structural height.

In addition, a technique is proposed in which the inclined moving plate is attached in parallel to the upper part of the vertical moving plate coupled to the vertical rail, and the fixed selection part is attached to the back of the inclined moving plate to selectively move the movable workbench vertically and inclinedly. However, this is structurally decisive, which can not be fused multiple window frame aggregate at the same time, and compared to the simple function of fusion welding the aggregate surface of the aggregate, the structure is complicated and difficult to use is inherent together. There remains a problem that greatly degrades the poor working environment and productivity.

Recently, the above-mentioned conventional problem has been solved by the patent registration No. 258734 'Thermal fusion apparatus of the window frame aggregate', which is filed by the present applicant, which opens a plurality of window frame aggregates whose ends are cut at a certain angle. After placing them on the welding machine in turn, the control operation is performed so that the clamping of each corner and the melting and fusion bonding of the adhesive surface can be simultaneously performed at each corner of the window frame, thereby minimizing the defective rate of the product due to warping or bonding error. In addition, the company has improved the work environment and productivity.

However, even in the above case, since only one window frame is produced in one process according to the control operation of the device, there is a problem of inefficiency, such as reduced productivity compared to the operation rate of the device.

Thus, the present applicant is configured to stack up and down a plurality of sets of materials in order to double productivity and workability compared to the operation rate of the device as described above, and simultaneously fusion-bonded together to manufacture two sets of window frames in one operation. There has been provided a thermal welding device for aggregates.

However, the present applicant's pre-registered invention has to improve the process that is not efficient and can not maximize productivity because it allows to remove the beads by fusion bonding two sets of window frames in one operation and then using a separate finishing remover. There was still a problem.

Therefore, the present invention was created in order to solve the problems of the applicant's above-listed invention and improve the productivity by maximizing productivity. The purpose of providing the same is to provide a plastic joint when manufacturing a plurality of sets of plastic chassis for a window frame. The material is clamped up and down, and the thermal bonding between the materials is achieved using a heating plate, and after cooling, the beads formed on the joint surface can be neatly removed using a plane cutter, a vertical cutter, and a rail groove cutter.

Another object of the present invention is that when a plurality of sets of flat cutters mounted on the corners scrape and remove beads formed on the upper and lower surfaces of the plurality of materials at the same time, the vertical bead removing device operates to lower the beads generated at the joined corners. By removing them at the time of rise, the processing surface is neatly processed, and the beads formed in each rail groove of the raw material are pushed strongly by the cutter from the outside to the inside to remove the bead from the joint surface, and at the same time, they are joined to the inner surface of the rail groove. The purpose is to reinforce the joint surface at the same time as removing the bead, thereby maintaining a more solid joint state and improving productivity and workability.

After welding the present invention having such a structure, the operation and effects of the bead removal operation will be described as follows.

First, pressing the start button on the operation panel raises the reference plate, which is a guide plate, and the operator A, A ', B, B', C, C 'D, D' to match the cross section of each base material on both sides of the reference plate. The base material is sequentially stacked and placed on the base material.

Next, the clamp assembly (50, 50 ', 60, 60') is operated by the cylinder operation to clamp each end of the base material,

The moving frame of the left and right heads is retracted by the cylinder operation.

At this time, the reference plate is lowered and at the same time the heating plate (H) enters.

After the heating plate (H) enters the moving frame is advanced to melt the cross section of each base material as a joint surface.

At this time, weaken the pneumatic pressure to keep only the state in which the base material is in contact with the heating plate (H), and after a certain period of time, after the heating plate (H) retreat to its original position, the moving frame is advanced and the base material is bonded to each other. In this case, the pneumatic force is made stronger, so that the joint can be made stronger.

In other words, by adjusting the pneumatic pressure, the pressure at the time of melting, thermal fusion, and cooling is strongly controlled to obtain more firm adhesion.

Next, the cooling process for removing the beads is carried out. In the past, the air-cooling method was selected, and after the base metal was bonded, the substrate was left uncured for a predetermined time and cured. However, the compressed cooling air was passed through the air nozzle (8). By spraying, the time required for cooling is greatly reduced and productivity is improved.

In this way, after the cooling air is injected through the air nozzle 8, the horizontal cutting module 7, which is a bead removing device for the upper and lower surfaces of the base material, is operated by the control system and is generated in the plane of the base material which is stacked up and down. The beads are removed from each of the upper and lower surfaces, and the vertical surface bead removing device 9 is operated to remove the beads generated at the joined corners of the base material at the time of falling and ascending, thereby treating the processed surface neatly.

The vertical bead removal device (9) is formed in the upper and lower cutting edge 91 is operated by each during the lowering and ascending, so when the end only when the end of the bead is not completely removed, so once again when removing the processing surface neatly To be processed.

When the removal of the vertical bead is completed, the 'c' groove bead removal cutter 6 installed in the rear middle portion of the corner of the clamp assembly 50, 50 ', 60, 60' is reciprocated to operate the rail groove of the base material. To remove the beads generated in

At this time, the cutter 61 strongly pushes the beads formed in the rail grooves from the outside to the inside to remove the beads of the bonding surface, and joins them to the inner surface, thereby removing the beads and reinforcing the bonding surface. To maintain a firmer bond.

According to the present invention, when the plastic chassis for the window frame is manufactured in a plurality of sets, the plastic joints are clamped up and down on the plastic joints, and then heat-bonded between the materials using a heating plate, and after cooling, the beads formed on the joint surfaces are connected to the plane cutters. Not only can be removed neatly by using vertical cutter and rail groove cutter, but also by reinforcing the bead to the inner surface of the rail groove, it serves to reinforce the joint surface at the same time as the bead is removed to maintain a more solid joint state. It is obvious that this is a very beneficial invention that can achieve very useful effects.
