Description

Filter manufacturing equipment {a filter manufacturing equipment}

The present invention relates to a filter manufacturing apparatus, and more particularly, to a filter manufacturing apparatus for manufacturing by fusion by positioning a cylindrical filter paper between two end cover surfaces in a molten state.

Generally, filters are classified into various types according to their shape and function, and all of them mainly aim to remove foreign substances in oil or air. Among these filters, there is a cylindrical filter 10, which has end covers 11 formed at both ends of the cylindrical filter paper 12 as shown in FIG. 1. The reinforcing metal member may be formed between the end covers 11 to maintain the rigidity of the filter 10.

These filters are required to be disposed of after use, and one of the common methods of disposal is landfilling. However, due to the serious environmental pollution problem, it is necessary to collect and dispose of used waste. It came to demand. Therefore, it is urgent to develop a product that can minimize environmental pollution.

Another method of disposal can be disposed of by incineration, but in the case of filters equipped with reinforcing metal members, another processing step is required because the metal members remain intact even after incineration. There is a problem that is not practical because of the economic burden on the treatment.

In order to solve this problem, these days, a filter paper having sufficient rigidity as a filter is used, and one that is free of a reinforcing metal member is mainly used. The reason is that it is possible to minimize the environmental pollution problem by collecting after use and simply incineration.

Such a filter is manufactured by fusing two end covers on both ends of a cylindrical filter paper. The existing filter manufacturing apparatus moves along the conveyor in the preheating furnace in which the infrared heater is operated to preheat the end cover, and puts the preheated end cover on the mold and does not come into contact with the end cover (usually 2-3 times). Mm) and heated with a plate-shaped infrared heater.

However, in the conventional filter manufacturing apparatus, since both the end cover 11 and the infrared heater of the filter 10 are fixed and applied by heat radiated from the infrared heater, the distance between the end cover 10 and the infrared heater as well as the infrared heater According to the arrangement of the local temperature deviation was too severe, and this causes the distortion of the end cover 10 is easy to occur and if the distortion of the end cover 10 occurs, the melting is not uniform, so that the proper fusion is impossible There was this.

In addition, it is impossible to adjust according to the size of the end cover 11 of the filter 10, so it is possible to produce only a single type of filter, which increases the economic burden of having each type and is not suitable for small quantity production of many models. There was a problem.

An object of the present invention has been researched and developed to solve the conventional problems as described above, when the end cover is continuously supplied to the mold of the mold rotation shaft of the upper / lower rotary table, respectively, preheating and heating as the mold rotation shaft is rotated The present invention provides a filter manufacturing apparatus which enables continuous mass production by sequentially repeating the operation of supplying filter paper at the time when the surface is melted and thus melted and fused together.

Another object of the present invention is to arrange two or more heating sources in the vane to radial direction in a position proximate to the surface of the end cover and to rotate the end cover on the mold with the mold to melt the two end cover surfaces uniformly. To provide a filter manufacturing apparatus.

Third cylinders 150a and 150b are installed to press and rotate the rotation shaft 124 in the centerline direction, and the third cylinders 150a and 150b are provided through the first brackets 151a and 151b. It is mounted on.

The present invention configured as described above will be described in detail the filter manufacturing process of the finished product by fusion of the end cover to the cylindrical filter paper.

First, when the power switch is turned on, the roller driving motor 146 of the roller driving device 140 is driven so that the roller 144 is rotated, and the vacuum pump is driven so that the upper / lower rotary tables 120a and 120b are always on. The mold 125 is kept in a state in which a suction force is applied.

The operator seats the end cover 11 on the mold 125 of the mold rotating shaft 124 at a position where the heating source 134 is not installed at the upper and lower rotating tables 120a and 120b of the rotating shaft 111. At this time, the mold 125 on the upper rotary table 120a is absorbed by the suction force of the vacuum pump that sucks the outside air through the suction hole 127 on the surface on which the end cover 11 is seated. When the end cover 11 is placed on the mold 125 on the lower rotary table 120b, it is naturally seated and fixed.

After the end cover 11 is seated on the mold 125 of the mold rotating shaft 124 as described above, the driving motor 115 is driven to rotate the gear 114 at the bottom of the rotating shaft 111 by 1/5 to stop. As the fourth cylinder 206 is operated, the block 205 is guided forward by the guide 204 to fix the stopper 114a of the gear 114 to fix the gear 114 in the correct position.

At the same time, since the pinion 203 of the filter paper rotating shaft 201 is engaged with the gear 114 at the lower end of the rotating shaft 111, the filter paper supplying device 200 together with the upper / lower rotating tables 120a and 120b of the rotating shaft 111. As the filter paper rotating shaft 201 is rotated 180 °, the mold 125 and the filter paper holding unit 210 on the upper and lower rotary tables 120a and 120b side of the mold rotating shaft 124 form one concentric plane and stop. do.

As described above, the upper and lower rotary tables 120a and 120b on the rotary shaft 111 are stopped by one-fifth rotation to be positioned at the upper and lower portions of the end cover heating apparatus 130 while the pulley 126 of the mold rotary shaft 124 is rotated. The mold rotating shaft 124 and the mold 125 are rotated by contacting the roller 144 driven by the roller driving motor 146 of the roller driving device 140. At this time, the second cylinder 142 absorbs the impact when the pulley 126 of the mold rotation shaft 124 of the upper and lower rotary tables 120a and 120b touches the roller 144 of the roller drive unit 140. Is, of course, in contact with a constant tension.

As such, when the mold rotation shaft 124 starts to rotate, the first cylinder 135 on the arc-shaped bracket 132 on the end cover heating device 130 is operated, and the operating bracket 133 is operated by the first cylinder 135. This rise or fall causes the heating source 134 of the operating bracket 133 to approach the end cover 11 on the mold 125.

As the operation bracket 133 approaches the end cover 11 of the mold 125 as described above, power is applied to the heating source 134 on the operation bracket 133, and thus the heating source 134 is instantaneously. The end cover 11 is heated by infrared radiation as well as emitting high heat and light. After the end cover 11 is heated for a predetermined time, the first cylinder 135 of the arc bracket 132 is operated again, and the operating bracket 133 is raised or lowered by the first cylinder 135 so that the mold The heating source 134 of the operating bracket 133 is separated from the end cover 11 on the 125.

When the heating process of the end cover 11 is repeated while being moved three times, the end cover 11 is melted and its surface is in a good state of fusion.

As such, when the end cover 11 on the mold 125 is moved to the last heating step, the fifth cylinder 215 of the filter paper supply device 200 is operated by the controller, and the rod of the fifth cylinder 215 is The holding member 212 moves to the outside by rotating the circular ring 213 and moving the holding member 212 radially outside the circular hole 211a by the pin 212c fitted in the long hole 213a of the circular ring 213. It will happen. At this time, when the operator inserts the cylindrically spread filter paper 12 into the arc-shaped piece (212a) constituting the holding member 212, the support plate member 222 of the filter paper support unit 220 supports the lower end of the filter paper 12, Set it to the position of the height.

When the filter paper 12 is placed on the backing plate 222 as described above, the fifth cylinder 215 is operated again, and the rod of the fifth cylinder 215 rotates the circular ring 213 in the opposite direction to the circular ring. The pin 212c fitted in the long hole 213a of the 213 moves the gripping member 212 toward the center of the circular hole 211a so that the arc-shaped piece 212a of the gripping member 212 is lifted up and closed. Will form a circle. Accordingly, the filter paper 12 is gripped while being shaped into a pleated circle.

The filter paper holding unit 210 of the filter paper supplying device 200 in which the filter paper 12 is gripped as described above is equipped with upper and lower rotary tables 120a and 120b of the rotating shaft 111 rotated 1/5 of the gear 114 at the bottom thereof. ), The holding member of the mold 125 and the filter paper holding unit 210 on the mold rotating shaft 124 of the upper / lower rotating tables 120a and 120b by rotating the filter paper rotating shaft 201 by the pinion 203 engaged with the pinion 203. 212 stops in one concentric plane. The end cover 11 seated on the mold 125 on the mold rotation shaft 124 is melted in a state where the surface thereof is suitable for fusion.

As described above, the mold rotation shaft 124 is positioned at the upper and lower ends of the gripping member 212, and the third cylinders 150a and 150b positioned at the upper and lower ends of the mold rotation shaft 124 are stopped after being stopped in a plane concentric manner. The mold on the mold rotating shaft 124 is operated by simultaneously pressing the mold rotating shaft 124 on the upper and lower rotating tables 120a and 120b toward the arc-shaped piece 212a by the rods of the third cylinders 150a and 150b. 125 is in contact with the upper and lower ends of the arc-shaped piece (212a).

Therefore, the upper and lower ends of the filter paper 12 in the holding member 212 are to dig into the molten surface of the end cover 11 to be fused.

At this time, when the mold 125 of the mold rotating shaft 124 touches the upper and lower ends of the gripping member 212, the suction force acting on the suction hole 127 of the mold 125 is released, thereby causing the end cover 11 to be removed. Is left in the gripping member 212 in a state fused to both ends of the filter paper 12.

When the rods of the third cylinders 150a and 150b that have been raised or lowered are returned to their original positions, the mold rotating shaft 124 is returned to its original position by the elastic force of the spring 129, and then the drive gear 116 is rotated at a predetermined number of revolutions. Only as much as it is driven and the upper / lower rotary table (120a, 120b) of the rotary shaft 111 and the filter paper holding unit 210 of the filter paper rotating shaft 201 is interlocked by the drive motor 116 is stopped by rotating. In other words, the upper and lower rotary tables 120a and 120b are rotated 1/5 and the filter paper supply device 200 is rotated 1/2.

As such, after the filter paper holding unit 210 of the filter paper supplying device 200 is rotated 1/2, the fifth cylinder 215 is operated, so that the holding member 212 interlocked by the fifth cylinder 215 is moved outward. As a result, the filter of the finished product in which the end cover 11 is fused to both ends of the filter paper 12 in the arc-shaped piece 212a is supported only by the support plate member 222 of the filter paper support unit 220.

In this state, since the sixth cylinder 223 of the filter paper support unit 220 is operated and then returned to its original position, the backing plate material 222 connected to the rod of the sixth cylinder 223 is also rotated downward to have a horizontal state. It will return to its original position. Therefore, the filter of the finished product placed on the backing plate 222 of the filter paper support unit 220 is guided to the bottom.

After the filter 10 in the gripping member 212 is discharged, the filter paper 12 opened in a circular shape is inserted into the arc-shaped piece 212a of the gripping member 212, and then the fifth cylinder ( The 215 is operated and the rod of the fifth cylinder 215 rotates the circular ring 213 in the opposite direction so that the pin 211c fitted into the long hole 213a of the circular ring 213 is held by the holding member 212. By moving toward the center of the circular hole 211a, the arc-shaped piece 212a of the holding member 212 is retracted to form one closed circle. Accordingly, the filter paper 12 is gripped while being shaped into a pleated circle.

At the same time, the end cover 11 is mounted on the mold 125 of the mold rotation shaft 124 at the position where the heating source 134 is not installed in the upper and lower rotation tables 120a and 120b. At this time, the mold 125 on the upper rotary table 120a is absorbed by the suction force of the vacuum pump that sucks the outside air through the suction hole 127 on the surface on which the end cover 11 is seated. When the end cover 11 is placed on the mold 125 on the lower rotary table 120b, it is naturally seated and fixed.

Thereafter, the drive gear 116 is driven only by a predetermined number of rotations, and the filter paper gripper of the upper / lower rotation tables 120a and 120b and the filter paper rotation shaft 201 of the rotation shaft 111 interlocked by the driving motor 115. The unit 210 is rotated and stopped. That is, the upper and lower rotary tables 120a and 120b are rotated 1/5 and the filter paper supply device 200 is rotated 1/2.

By carrying out the above-described process continuously, the mass production is possible by performing the batch operation continuously and sequentially.

As described above, unlike the conventional filter manufacturing apparatus manufactured by fusion welding using the radiant heat of the infrared heater in a static state where both the end cover and the infrared heater are fixed, the filter manufacturing apparatus of the present invention is close to the surface of the end cover. At least two heat sources for heating are arranged in a vane-to-radial direction and the end cover on the mold rotates together with the mold, thereby having a unique effect of uniformly melting the two end cover surfaces.

In addition, the present invention is to supply the end cover continuously to the mold of the mold rotation axis of the upper / lower rotary table, respectively, the pre-heating and heating as the mold rotation axis is rotated to melt the surface and supply the filter paper at this time of melting and fusion operation By repeating sequentially, there is an effect that enables continuous mass production.
