〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

1 and 2 are a schematic front view and a schematic plan view according to an embodiment of the continuous siding material manufacturing apparatus of the present invention.

This continuous production apparatus for siding material is equipped with two uncoilers 11 and 12 on the base end side of the production line, and a coil 15 of a thin metal plate that is carried and mounted on each uncoiler 11 and 12 by a coil car 13 and 14. 16 are alternately fed out and supplied as a base material 17 of a siding material in the subsequent steps.

These uncoilers 11 and 12 are arranged before and after the molding line, the 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 from the uncoiler 11 without interfering with the uncoiler 12. Any of the uncoilers 11 and 12 is configured to support the coils 15 and 16 by a cantilever support method, so that transfer from the coil cars 13 and 14 can be easily performed.

Next to these uncoilers 11 and 12, while feeding or pressing the base material 17, a pinch roll joint device 19 for connecting the old and new coils 15, 16 is provided, and when the coils are connected, the preceding coil, For example, the rear end of the coil 16 is pressed by the pinch roll 20 to be in a fixed state, and the following coil, for example, the front end of the coil 15 is butted on the table 21 and connected with an adhesive tape.

When the coils 15 and 16 are connected, an accumulator 22 is installed in front of the pinch roll joint device 19 in the line direction in order to supply the coils without any trouble.

This accumulator 22 has a fixed roll 23 and a movable roll 24.
Are provided, and each movable roll 24 can move up and down integrally or individually. Then, normally, while the base material 17 linearly passes between the lower side of the fixed roll 23 and the upper side of the movable roll 24 at the lowest position, at the time when the remaining amount of the preceding coil 16 becomes small. The movable roll 24 is raised so as to store the coil in a meandering state, and the movable roll 24 is gradually lowered so as to pay out the coil 16 accumulated in the accumulator 22 during a time required for connecting the coil.

In front of the accumulator 22 in the line direction, the base material 17
Pinch roll 25 and down-cut shear for feeding
26 and 26 are arranged, the down-cut shear 26 is operated to cut the base material 17 at the end of the work of forming the siding material or when a trouble occurs, and a new forming operation is stopped.

A heater 27 is installed in front of the down-cut shear 26 so that the coating film coated on the base material 17 is heated so as not to break during the embossing process in the next step. There is. The heater 27 is, for example, a warm air system in which hot air heated by steam is sent to heat the base material 17, and the softening point of the coating film is lowered by increasing the temperature to make it easier to stretch and to improve workability. Improve. The positions of the heater 27 and the down cut shear 26 may be reversed.

The base material 17 thus heated and heated is sent to the embossing machine 28.

The embossing machine 28 embosses a concavo-convex pattern between upper and lower rolls 29, and the gap between the rolls 29 is set based on the thickness of the base material 17.

The base material 17 having the uneven pattern formed by the embossing machine 28 is not flat due to the residual strain due to the embossing.

Therefore, the base material 17 is sent to the leveler 30 to be flattened and then sent to the next step.

The leveler 30 is composed of, for example, a roller leveler, and upper and lower rollers are alternately arranged so as to project vertically from the molding line, and the base material 17 is straightened while being stretched.

After that, the straightened base material 17 is sent to the molding machine 31 and molded in accordance with the cross-sectional shape of the siding material. This molding machine 31, for example, is used to form a combination of 20 to 25 continuous forming rolls, each time the cross-sectional shape of the siding material to be formed is different, it is necessary to replace the forming roll,
In this molding machine 31, a roll stand 33 that moves in a direction perpendicular to the molding line is placed on a slide base 32, and a molding roll for molding a siding material having a uniform thickness in the cross-sectional direction for flat attachment is placed on the roll stand 33. Two types of forming rolls 34 and 35, such as forming rolls for forming siding material, which have different thicknesses in the cross-sectional direction and are inclined surfaces for armoring, can be set in advance.

Therefore, molding of siding materials with different shapes can be achieved in a short time, and if two sets of molding rolls with the same shape are prepared, maintenance and inspection of unused molding rolls can be performed before the next use. Ready for smooth continuous operation.

The base material 17 thus formed into a predetermined shape is a preheater.
Sent to 36. The preheater 36 is for heating up to about 30 to 40 ° C. in advance before injecting the expandable synthetic resin onto the base material 17, and raises the temperature to an appropriate temperature for foaming urethane (foam). In this case, for example, steam is used as the heat source, and hot air is generated by the steam heater 37 and circulated by the blower 38.

In front of the preheater 36, a foam material injecting machine 39 attached to a gate type frame is provided so that the moving frame 40 can be moved back and forth in the line direction. The moving frame 40 has a rotary stirring mixer. 41 is mounted so as to be swingable by a crank mechanism or the like, and an inverted Y-shaped nozzle 42 is mounted at the lower end of the mixer 41.

Then, for example, an isocyanate-based component and a polyol-based component are supplied to the mixer 41, and immediately after mixing with stirring, the mixture is uniformly injected into the base material 17 from the nozzle 42 in the rocking state.

Therefore, even if foaming starts by stirring and mixing the foamable synthetic resin, the base material 17 is not deposited and deposited in the nozzle 42.
Can be injected into the mixer 41 and the nozzle 42
Since the whole is swung in the direction perpendicular to the line and the foam material is injected in a two-row meandering state, it is possible to inject it uniformly.

In addition, the foamable synthetic resin has a foam-hardening conveyer 43 in the next step after a lapse of time from the start of foaming to the completion of the rise time.
When changing the injection position of the foamed material to the base material 17 depending on the line speed, the moving frame 40 is run to deal with it.

In front of the foam material injecting machine 39, a back surface material 44 such as paper, which is placed on the foam material so as to face the base material 17, is supplied in order to
The backing material feeders 45 and 46 of the stand are installed on the upper part of the molding line, and by alternately feeding the coiled paper, it is possible to continuously feed.

Since the back surface material 44 such as paper does not interfere with the subsequent steps even if they are overlapped at the time of connection, the connections are made by stacking and fixing with an adhesive tape without butt connection.

The backing material 44 is sent to the backing material heater 47, and is heated by hot air by a steam heating type warm air heater to prevent problems such as paper absorbing moisture and curling. .

As the backing material 44, not only paper such as kraft paper or asbestos paper, but also aluminum foil or plastic sheet is used. The temperature to be heated by the backing material heater 47 varies depending on its type. Since the heater 47 is an independent steam heating type, it is easy to optimally control the temperature.

The back surface material 44 heated in this way is pressed at both ends of the base material 17 so as to wrap the foam material injected onto the base material 17 by the pushing unit 49 to which the guide rollers 48 are attached so as to correspond to the widthwise ends of the siding material. Is pushed into.

After this, the foam material is injected onto the base material 17, and is sent to the foam curing / conveying machine 43 in a state where the back surface material 44 is applied, and the foam material is foamed and cured while being conveyed, and is integrated with the base material 17. To do.

The foam curing and transporting machine 43 is configured such that the base material 17 is placed on the bottom endless transport mechanism 52 composed of a slat conveyor 51 for transporting the base material 17, and the back surface material 44 to transport the foaming pressure while supporting the foaming pressure. It is configured with the upper endless type transport mechanism 54 configured with the belt conveyor 53, and the belt conveyor 53 located on the upper side is not only the case where the thickness of the siding material in the width direction is constant, but also the thickness. The whole can be tilted so that it can cope with the case of a uniform change.

As the tilting mechanism of the belt conveyor 53, the tilting nuts 57 that come into contact with the supporting frame 56 of the belt conveyor 53 on the slopes are screwed into the left and right screw shafts 55 that move up and down the entire belt conveyor 53 by operating simultaneously, and tilting is performed. The support shafts 58 at both ends of the nut 57 are inserted into the fixing fittings 59 attached to the support frame 56, and the contact surfaces of the fixing fittings 59 with the fixing frame 60 are also formed with inclined surfaces 61.

Therefore, in order to operate the screw shafts 55 on both sides of the belt conveyor 53 at the same time, the manual clutch disposed in the middle is connected to connect the left and right operation shafts, and one of the screw shafts 55 is moved by the lifting motor. After being rotated by to set a predetermined tilt angle, the tilting nut 57 is moved up and down by engaging the manual clutch again, and the tilting nut 57 and the support frame 56 connected via the support shaft 58. Inclined, with each slope supporting frame 56 and fixed frame 60
The belt conveyor 53 is held in a slanted state in close contact with.

In this tilted state, the entire belt conveyor 53 is tilted, so problems such as belt meandering are avoided.

The upper and lower endless transfer mechanisms 52 and 54 are provided in the casing 62.
It is housed inside and can be heated to the optimum ambient temperature for foaming and curing of the foam material, and the hot air produced by the heater 63 using steam as a heat source is circulated.

This warm air is blown upward from the nozzle in the loop at the lower slat conveyor 51, while hot air is blown directly on the belt surface at the upper belt conveyor 53. The casing
The atmospheric temperature inside 62 can be maintained at about 50 to 90 ° C.

The siding material whose foaming and hardening has been completed in this way is carried out from the foaming and hardening carrier 50 and sent to the sealant insertion machine 64.

This sealing material inserting machine 64 is one for continuously inserting a soft rod-shaped sealing material 65, for example, a foamed product of rubber or plastic into a trough-shaped sealing groove 17a formed on the side surface of the base material 17 of the siding material. is there. For this reason, drums 67 each having a sealing material 65 wound around two vertical guide shafts 66 are mounted, and pulled out by guide rolls 68 and pinch rolls arranged above and below. It is configured so that it is sent to the vicinity of the seal groove 17a and is pushed into the seal groove 17a by the pushing roll 71 facing the receiving roll 70.

Then, it is possible to continuously supply the toner by alternately feeding it out from the two drums 67, and the guide roller 68 and the pushing roll 71 are driven by using the drive source of the foam curing and conveying machine 43 at the preceding stage, thereby synchronizing with the line speed. You can then drive.

The siding material containing the sealing material 65 in this manner is sent to the cutting machine 72.

This cutting machine 72 comprises a backing material 44 of a siding material, a first cutting blade 73 for cutting a foam material, and a second cutting blade 73 for cutting the base material 17 next.
A cutting blade 74 is provided so that the first and second cutting blades 73 and 74 can be moved to a predetermined position to be cut by a signal from a measure roll 75 that comes into contact with the siding material and measures the length of the fed siding material. Has become.

That is, when the length measurement signal from the measure roll 75 approaches the cutting length of the siding material, the acceleration control of the cutting machine 72 is started, and the tuning control is performed when the set cutting length and the feeding length of the siding material become equal. Switch to the first cutting blade 73
The back material 44 and the foam material are cut with.

After this, the measuring signal of the major roll 75 again causes the cutting machine 72 to move so that the second cutting blade 74 is positioned at the position cut by the first cutting blade 73, and the siding material is pressed down while performing synchronization control. The blade and the horizontal blade are brought into forward contact, and the base material 17 is cut by the second blade cutting blade 74 to complete the cutting. After this, the cutting machine 72 is returned to the standby position to prepare for the next cutting.

The siding material cut in this way is sent to a packing device (not shown) for packing.

According to such a continuous siding material manufacturing apparatus, the uncoilers 11 and 12 are sequentially connected while supplying the coils 15 and 16 serving as the base material 17, and the back surface material 44 includes two back surface material feeders 45 and 15. By sequentially feeding from 46, the siding materials 1 and 2 can be continuously manufactured.

In addition, when switching between the production of two types of siding materials 1 and 2 having different cross-sectional shapes, the roll stand 33 on the slide base 32 of the molding machine 31 is moved and the upper belt conveyor 53 of the foam curing conveyor 43 is moved. It can be easily handled by adjusting the inclination.

Furthermore, in continuous manufacturing, it is necessary to prevent the foam material from accumulating and hardening in the foam material injecting machine 39.
Since the nozzle 42 is directly attached to 41 so that the passage through which the foam material passes after mixing is made as short as possible, continuous injection can be performed without any trouble.
