Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an apparatus that is used as an exterior material for buildings, etc. and allows continuous production of noiding materials.

[Conventional technology]

11 Siding material is one of the exterior materials for buildings, etc.
After forming the metal thin plate into a spade shape, foaming synthetic resin such as polyurethane is injected into this part and allowed to harden and rest, reducing the weight and making handling and construction easier.
Along with making it easier, Fli:! It is also used for 'A' and shield height.

l of this kind of siding material! The manufacturing equipment that performs I'I construction uses, for example, a thin metal sheet fed out of an uncoiler as a base material, sends it to an embossing machine to create an uneven pattern, and then bends both edges in the width direction using a forming machine. The foam material is injected into this 1 liffl-shaped gutter into a gutter shape (injected with a 4-injecting rod, and the foaming pressure is sent to the foam curing lIQ feed reed and regulated while curing. Ta.

[Problem that the invention seeks to solve]

In this type of knitting equipment, 1
A coil of about 000 to 2000 m is installed in an uncoiler to form the siding material, and when the coil runs out, the manufacturing equipment is stopped at -D, and a new coil is connected.
After passing a new coil through each unit, molding is restarted.

This means that although the time required to connect the coil is approximately 20 seconds, it is sufficient to connect the coil.
This is because they often operate at high speeds of 0 to 50 m/1n, and connections often fail.

Therefore, it is necessary to cut and remove the base material on the molding line during molding, resulting in a lot of waste.

Therefore, connect the old and new coils while in operation t3
However, if the coils overlap during the connection time, they will not be able to pass through the embossing machine, which has a clearance set for one coil, and will cause large problems such as giving a 1 [] mark to the processing opening. There is a possibility that there is a problem.

In addition, similar to the problem of continuous supply of the thin metal plate), it is necessary to smoothly continuously supply the actual face material of the paper hat that is applied to the foaming month-1-.

This invention was made in view of the problems of the prior art, and even if the forming speed is high, the coil serving as the base material cannot be properly (
In addition to being able to continuously supply the backing material, continuous knitting is possible! ! The aim is to provide a JW device.

[Means for solving problems]

In order to solve the above-mentioned problems, the continuous manufacturing apparatus for siding materials of the present invention includes two uncoilers that feed out the base material in a continuous UIC manner, and a feed rate corresponding to the connection time of the base material frozen from these uncoilers. An accumulator that collects water, a heating plate that prevents the coating film on the surface of the base 14 from breaking, and a pattern on the surface of the base 14 between the upper and lower rollers. The level to be removed, the molding machine that molds the early wood into a roughly gutter-like shape corresponding to the cross-sectional shape of a predetermined 1-niering material, and the preheater that heats the molded base material to a temperature close to 1 grade (21 people of 4). Then, the dried foam material is injected into the gutter, and the foam material is movable in the direction of the line to adjust the foaming rate and swingable in the direction perpendicular to the line to inject uniformly. , two real face material feeders that continuously supply the real face material applied onto the foam material to the ACH, and upper and lower machines that are arranged to sandwich the 2J material and the real face material and harden and convey them while supporting the foaming pressure. A foam curing conveyor (1) equipped with an endless conveyance mechanism, a sealing material inserting machine that continuously inserts the sealing material into the sealing groove formed on the side surface of the bLL material in which the foamed material is integrally hardened, and V) It is characterized by being made of a cutting machine.

[For production]

The base material can be fed out alternately from two uncoilers, and the length of the base material that needs to be fed out during the time required for connection is stored in an accumulator, and at the time of connection,
By feeding out the base material in the accumulator to the next process and subsequent processes, the new and old glue materials are connected so that they do not overlap, and the actual face material is also fed alternately from the two back material feeders.J:

A soft rod-shaped sealing material that improves sealing performance can be continuously inserted into the intersection U using two sealing material insertion machines into the sealing groove, making continuous production of siding material possible with Haku's equipment, improving production efficiency. We are trying to reduce waste at Shrine 11.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIGS. 1 and 2 are a schematic front view and a schematic plan view of an embodiment of a continuous production apparatus for gluing materials of the present invention.

This continuous production equipment for siding material is B of the production line.
There are two uncoilers 11.12 on the r5 side, and each uncoiler 11.12 has a coil car 13.1/
Coils 15 and 16 of thin metal sheets transported and mounted at I are alternately unwound and supplied as a base material 17 of siding material to the next process and subsequent steps.

These uncoilers 11 and 12 are arranged before and after the molding line, and a support roller 18 is provided on the uncoiler 12 on the downstream side of the molding line, and the base material 17 can be fed out from the uncoiler 11 without interfering with the uncoiler 12. , both uncoilers 11.12 and coils 15.1
6 is supported in a cantilevered manner so that it can be easily transferred from the coil cars 13 and 14.

Next to these uncoilers 11.12, 7. Shrine 174
As well as letting out and pressing down, new and old coils 15.16
Pinch roll gee-1-in-1-device 1 for performing 18 continuations of
When connecting the coil, the rear end of the preceding coil, for example, coil 1G, is provided with a pin block ``]]-ru 2.
Press down with 0 and connect the ends of the coil 5 in a fixed state (for example) with the table 21 with 1 & 2 tape.

When connecting the coils 15 and 16, a comb rake 22 is placed in front of the pinch roll join 1 to the device 19 in the line direction in order to supply the coils without any trouble.

This accumulator 22 can be used with the fixed roll 23
A plurality of rolls 24 are installed, and each movable roll 24 is
・The body or individuals can move up and down. (Normally, while the base material 17 passes in a straight line between the lower side of the β1 fixed roll 23 and the upper side of the movable roll 2/l at the lowered position tJ, the remaining coil 16 When the amount becomes small, the movable roll 24 is turned upside down so that the coil is stored in a meandering state, and the movable roll 24 is moved so that the coil 16 stored in the accumulator 22 is paid out for the time required to connect the coil. Try to lower it gradually.

In front of the accumulator 22 in the line direction, a pinch roll 25 and a down cut shear 26 are arranged for sending out the base material 17.
6 is operated to cut the base material 17, and the new molding operation is stopped.

A heater 27 is installed in front of this down cut shear 26, and is heated to prevent the coating film applied to the base material 17 from breaking during the next process of embossing. ing. This heater 27 employs, for example, a four-way system that heats the base material 17 by sending hot pressure heated by steam, and by raising the temperature, lowers the softening point of the coating film, improves stretchability, combing, and workability. For improvement, the positions of the heater 27 and the down cut shear 26 may be reversed.

The base material 17 thus heated 71 is subjected to embossing process 1.
Sent to 28th.

This embossing process 28 is performed using rolls 29 arranged above and below.
This is used to emboss an uneven pattern between rolls 2 and 3.
The thickness of the base material 17 is determined by setting the thickness of the base material 17 as the base piece.

An uneven pattern was created by this embossing 11 m28; J U 17 was not flat due to the residual 2 from the embossing.

Therefore, this 1°1 material 17 is sent to the leveler 30 and leveled 11
] and then send it to the next process. .

This leveler 30 is, for example, a roller leveler.
The upper and lower rollers are arranged at cross-H so that they protrude above and below the molding line, and the base material 17 is pulled 1. Correct f.

After this, the straightened 1J material 17 is completed! S'! fl
31, where it is molded to correspond to the cross-sectional shape of the F-niding material. This molding machine 31 is, for example, 20 to 25) I
I! A combination of forming rolls is used.
Every time the cross-sectional shape of the Noiding Shrine becomes different,
It is necessary to replace the forming rolls, but in this forming unit 31, a roll stand 33 that moves in a direction perpendicular to the forming line is placed on a slide base 32.
3. There are two types of forming rolls, including a forming roll for siding with the same thickness in the cross-sectional direction for flat application and a forming roll for forming siding with a different thickness in the cross-sectional direction and a sloped surface for attaching armor. The forming roll 3' of 4.35 mm can be pre-let.

Therefore, it is possible to form cheap siding materials in one short time.
If you prepare two sets of molding rolls with the same shape, you can maintain and inspect the molding rolls that are not in use and prepare them for the next use. This allows continuous operation to be carried out smoothly.

1417 thus formed into a predetermined shape is fed to the preheater 36. This preheater 36 is made of SJ material 17
Before injecting the foamable synthetic resin on top, it is heated to about 30 to 40°C in advance to bring the stomach temperature to an appropriate temperature for foaming the urethane (foam). In this case, the heat source is
For example, using steam, hot air is generated by a steam heater 37 and circulated in the air blowing basin 3B.

In front of this preheater 36, a foam injection member 339 attached to the frame is provided so that a movable frame 40 can be moved back and forth in the line direction. 41 is mounted so that it can be swung horizontally by the crank, and the mixer 4
1, an inverted Y-shaped nozzle 42 is attached to the lower end thereof.

For example, the isocyanate 1-sa 41 contains
Immediately after the system component and the polyol component are supplied and stirred and mixed, they are uniformly injected into the base material 17 from the nozzle 42 of the moving shape 1.

Therefore, even if foaming starts due to stirring and mixing of the foamable synthetic resin, it can be injected into the material 17 without adhesion and accumulation inside the nozzle 42, and the mixer 41 and nozzle 42 can be swung in the direction perpendicular to the line. Since the foam material is injected in two meandering lines, it is possible to inject it evenly.

In addition, the foamable synthetic resin is transported to the next process for foaming and hardening after the time has elapsed from the start of foaming to the completion of the rise time.
It is necessary to feed the base material 17 depending on the line speed.
When changing the injection position of the foam material, avoid moving the moving frame 40.

In front of this foam material injection station 39, two actual surface material supply machines 45°/16 are installed on the molding line in order to supply the back material/14 such as paper to be applied onto the foam material so as to face the base material 17. It is installed at the top and is arranged so that the coiled paper can be fed continuously by alternately feeding the coiled paper.

Even if the actual surface materials 44 such as paper overlap during connection, there will be no problem in subsequent steps, so the connection is performed by overlapping them and fixing them with adhesive tape without butting them together.

This actual surface material 44 is sent to a heater 47 for the back surface 1, and is heated with warm air by a steam heating type hot air heater, so that defects such as the paper absorbing moisture and curling occur. prevent.

This back side 44/14 can be used not only for Kraft I-paper and asbestos paper 41, but also for aluminum foil and Plus Deck Sea 1-
etc., but depending on the type, the back material heater 47
Although the temperature to be heated differs depending on the type of material, the actual material heater 47 is an independent air heating type, so the temperature can be optimally controlled.

The thus heated actual surface material 44 is moved onto both sides of the base material 17 by a pushing unit 49 to which guide rollers 48 are attached corresponding to both ends of the siding material in the width direction, so as to wrap the foam material injected onto the base material 17. being forced into the department.

In this I5, foam material is injected onto the base material 17, and the force surface 44
44 is applied to the foam curing conveyor 43,
The foam material is foamed and hardened while being transported.
Make it one with 7.

This foam curing conveyor 43 is of an endless type on the lower side and is composed of a slat conveyor 51 on which the base material 17 is placed and conveys it! It is composed of an iQ transport mechanism 52 and an upper endless conveyor structure 54 which is composed of a belt conveyor 53 that conveys foaming pressure while supporting the foaming pressure through a backing material 44. 53 is designed so that the entire siding material can be tilted not only when the thickness in the width direction of the siding material is constant but also when the thickness changes uniformly.

As a tilting mechanism for the bell 1 to the conveyor 53, when operated simultaneously, the support frame 5 of the belt conveyor 53 is attached to the left and right screw shafts 55 that lower the belt conveyor 53 body.
The tilting nut 57 that contacts 6 on the slope is screwed in, and the supports J,'n'111158 at both ends of the tilting nut 57
are inserted into the fixing metal fittings 59 attached to the support frame 56, and slopes 61 are also formed on the contact surfaces of the five fixed fittings with the fixing frame 60.

Therefore, in order to simultaneously operate the threaded shafts 55 on both sides of the belt conveyor 53, a manual clutch disposed in the middle is released to connect the left and right operating shafts, and
After either one of the screw shafts 55 is rotated by the lifting motor and set to a predetermined inclination angle, the engagement clutch is engaged again. is raised and lowered, and the support frame 5f3 connected via the tilting nut 57 and the support shaft 58 is tilted (bevel 1), and each slope is in close contact with the support frame 56 and the fixed frame 60. The inclined state of the conveyor 53 is maintained.

In this tilted state, the entire belt conveyor 53 is tilted, so problems such as meandering of the bell 1- can be avoided.

In this way, the endless conveyor 1:52.54 below is housed in a casing 62, and can be heated to the optimal ambient temperature for foaming and curing of the foam material, using natural air as a heat source. The 'JA Ea' produced by the heater 63 is circulated.

This warm kite is heated by blowing hot air upwards into the loop from a nozzle in the lower slab (conveyor 51 part), while in the upper belt conveyor 53 part, hot air is sprayed directly onto the surface of the belt. The atmospheric temperature inside the casing 62 can also be maintained at about 50 to 90°C.

The siding material, which has been foamed and hardened in this way, is carried out from the foaming and hardening conveyor 50, where a sealing material is inserted and sent to 164.

This sealing material insertion 164 is inserted into the siding material 1. (A soft rod-shaped sealing material 65, such as a rubber or plastic foam product, is continuously inserted into a gutter-shaped sealing groove 178 formed on the side surface of the material 17. For this purpose, two vertical guide shafts are used. Drums 67 each wrapped with sealing material 65 are attached to 1. Guide rolls 68 arranged above and below.
43 and pinion rolls, and is sent out by a guide cylinder 69 to the vicinity of the old seal t: M 17 a of the siding month, and the receiver is pushed into the seal groove 17a by a push roll 71 facing the roll 70.

Then, continuous supply is possible by alternately feeding the two drums 67, and the guide roller 68 and push roll 71 are driven using the drive source of the foam curing conveyor 43 in the previous stage, so that the line speed is 1α. Doni-IiII
I'm hoping that I can have good luck.

In this way, the sealing material 65 is inserted and the iding material is sent to the cutting machine 72.

This cutting pattern 72 consists of a first cutting blade 73 that analyzes the back material/14 of the siding material and the foam material by 1.7
．． The 143rd and 143rd cutting blades 74 are equipped with a second cutting blade 74 for cutting the siding material 17, and the 143rd and j27
The second cutting blade 73.7/I is moved to a predetermined position for cutting.

When the measurement signal [; from the straw and measuring roll 75 approaches the cutting length of the 1y imagining material, the cutting 1g1n7
2 acceleration control is started, and when the set cutting length and siding material feed quality become equal, synchronization control 211 is started.
Nikiri? = 5 and then the first cut [cutting off the knife face material 44 and the foam material with the folding blade 73.

After this, due to the measurement of σf and the measuring roll 75, the second cutting blade 74 is placed at the position cut by the first cutting blade 73 (
Move the cut fgi172 so that it is 1", and set the tuning υI
At the same time, the lower blade and the side blade that hold down the first niding material are brought into contact with each other in a curved manner, and the second cutting blade 74 cuts the base material 17 to completely complete the cutting.

After this, the cut 1ff72 is returned to the special position to prepare for the next cut.

The siding material cut in this way is sent to a packing machine (not shown) and packed.

The siding material prepared in this way can be used, for example, as a flat siding siding VUI with a constant cross-sectional thickness as shown in Figure 2, or as an armor siding siding with a variable cross-sectional thickness. It is used as a siding material 2 and as an exterior material for buildings.

This J: eel (according to Noidingro's continuous production equipment, it becomes the base material 17 in uncoiler 11 and 12 in sequence) ile 1
5. Connect while replenishing 16, and connect the actual surface material 44.
Continuous production of reeding (A 1 and 2) can also be performed by sequentially feeding from two actual face material feeders 45 and 46.

In addition, two types of 1-noising materials 1.
2. Also, when switching the production of step 2, avoid moving the roll stand 33 on the slide base h2 of the molding machine 31.
This can be easily handled by simply adjusting the inclination of the belt conveyor 53 above the foam hardening conveyor 0!43.

Furthermore, in continuous production, foam material 11
It is necessary to prevent the foam material from curing in the mixer 1 (1), but it is necessary to attach the nozzle 42 directly to the mixer 1 (41), and then shorten the passage through which the foam material passes after mixing. This allows for continuous injection without any problems.

〔Effect of the invention〕

According to the present invention, which has been specifically explained above with one embodiment, it is possible to alternately feed out the base material from two uncoilers, and it is not necessary to feed out the base material during the time required for connection. A certain amount of base material is stored in an accumulator so that it can be supplied from now on, and the actual face material is also alternately supplied from two back material feeders and connected together, allowing continuous production of siding material.

In addition, since the foam injection machine can be moved in the line direction, the operator position can be changed so that the foam material is in the right time just before it enters the foam curing conveyor, making it always optimal regardless of line stray electricity. It can be sent to the next process in a foamed state.

Furthermore, since the foaming material can be injected in one movement in the direction perpendicular to the line, the foaming material can be uniformly poured onto the base material, and foaming can be carried out uniformly.
