Abstract

PURPOSE:To obtain a good heat insulation steel plate without generating slackness in a heat insulation material, by a method wherein a heat insulation material supply device is situated on a coil sent out through a pasting device, movable in parallel with the coil, and it moves at the same speed as that of the coil at the time of cutting off of a heat insulation material in the heat insulation material supply device. CONSTITUTION:A coil (a) is sent out through a coil supply device 1 and the top of the coil (a) is pasted by a pasting device in a laminator. A heat insulation material in a sheetlike state is cut into predetermined size and stuck to a pasted surface through a heat insulation material supply device 3, brought into contact with pressure by a press-contacting and cutting device 4, and the coil (a) is cut into predetermined size. The heat insulation material supply device 3 runs parallel with the coil (a) and at the same speed as that of the coil (a) at the time of cutting-off of the heat insulation material and in the meantime the heat insulation material is cut off while the sending- out of the heat insulation material is suspended. Therefore, neither a scar and slackness are generated between a confluence between the coil (a) and the heat insulation material and a cutter, or between the cutter and a feed roll, nor dimensional error and deviation in sticking positions are taken place. Therefore, it is unnecessary to suspend the laminator, and the operation can be performed continuously.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is capable of continuously attaching a sheet-like heat insulating material of a heat insulating steel plate used for roofing materials and the steel plate without stopping the machine. Efficient carp J →; Mis-N-L#Dumpling six-gome de arc su- (prior technology) Traditionally, insulating steel plates used for roofing are made by running a coil of thin steel plate and gluing it to the surface. In this method, one end of a sheet of heat insulating material was glued to the glued surface of the coil, and the heat insulating material was fed out as the coil traveled.

(Problems to be Solved by the Invention) However, it is necessary to cut the heat insulating material to a size corresponding to the size of the coil to be cut.

In order to cut the insulation material being sent out by the feed roll, wrinkles or slack may occur between the insulation material gripping position of the feed roll and the cutter, or there may be wrinkles or wrinkles between the point where the insulation material joins the coil and the cutter position. There may be problems such as errors in the dimensions of the insulation material or misalignment of the bonding position, and to prevent this, it is necessary to stop the running of the coil and the insulation material and remove the insulation material. If they were cut, there were problems such as a significant drop in the operating rate of the machine.

(Means for Solving the Problems) The present invention eliminates the above problems and makes it possible to obtain a good insulating steel plate without wrinkles or the like on the bonding surface between the coil a and the heat insulating material even during continuous operation. For this purpose, a coil supply device 1, a gluing device 2 for the coil a supplied from the feed device 1, and a heat insulating material feed device 3 for the coil a glued by the gluing device 2,
It consists of a device 4 for crimping and cutting the heat insulating material supplied from the heat insulating material supply device 3 and the coil a, and the heat insulating material supply device 3 is located on the coil a delivered from the gluing device 2. , is a coil laminator which is movable parallel to the coil a and is configured to be moved at least at the same speed as the coil a when the heat insulating material is cut by the heat insulating material supply device 3.

(Function) In the laminator configured as described above, the coil a is sent out from the coil supply device 1, pasted on its upper surface by the pasting device 2, and a sheet-like heat insulating material is applied to the pasted surface from the heat insulating material feed device 3. After the coil a is cut to a predetermined size and pasted, it is crimped by a crimping and cutting device 4, and the coil a is cut into a predetermined size.

When cutting the insulation material, the insulation material supply device 3 runs parallel to the coil a and at the same speed, and during this time, the feeding of the insulation material is stopped, and the insulation material is cut. Since it is cut, there is no tension between the cutter and the confluence of the coil a and the insulation material, or between the cutter and the delivery roll.
There will be no loosening, dimensional errors or misalignment of the laminator, and the laminator can be operated continuously without having to stop it.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

l is a coil supply device, and a coil a made of a steel plate with a thickness of 0.3 to 1.2 mm is a motor M with an electronic control device. It is hung on a creel 5 and sent to a pinch roll 8 via a measuring roll 7 driven by a motor M2 of a measuring device 6.

Reference numeral 9 denotes a punch hole punching device, which punches holes in the coil a according to the length measured by the measuring roll 7 and specified by the counter A. A hole is punched at each cut position. Further, the coil a is connected to the pinch roll 10 of the gluing device 2,
A pair of rolls 12', 1 pass directly under the gluing roll 12 via the measuring roll 11, and are pressed against the gluing roll 12 from below by a hydraulic or air cylinder C3 via a coil a.
2' allows the glue from the glue tank 13 to be applied to the upper surface of the coil a. Reference numeral 14 denotes a sensor such as a phototube for detecting punch holes, and the sensor 14 causes counters B and C, which are separately provided, to start counting the length using a measuring roll.

15 is a drying oven installed 2 degrees above the frame, and while the coil a passes through this drying oven, the glue applied on the coil a is kept in a semi-dry state so that it reaches the next pinch roll 29. It has become.

3 is a supplying device for a heat insulating material such as polyfoam, asbestos, glass fiber, etc., which is placed on the running path of the coil a between the drying oven 15 and the pinch roll 29, 2 degrees above the frame of the gluing device 2; The packet IB is installed on a pair of rails 19 provided in parallel with the frame, and the sheet-shaped heat insulating material protrudes above the frame 2°.
-H pool in the packet 1B and sent out onto the guide table 18 of the heat insulating material supply device 3 by the feed roll 17 provided on the side wall of the packet 1B. Further, the heat insulating material supply device 3
is a countershaft 20. from the driving motor M3 of the vinyl roll 10 of the gluing device 2. A gear (
(not shown) is attached, and the gear meshes with a rack (not shown) attached to the rail 19 so as to move forward, retreat, and stop on the rail 19 at the same speed as the coil a.

24 is a pinch roll for the heat insulating material sent from the guide table 1B, and is driven by a pair of belt transmission mechanisms 25 and 26 which are provided in a flexible manner from a motor M4. 27 is a cutter for insulation material, and pinch roll 2
The heat insulating material sent out from 4 is cut by being driven by a cylinder. A stopper 28 is provided at the tip of the rail 19, and is adapted to adjust the moving distance of the heat insulating material supply device 3. MS is a motor for an edge position controller that prevents both edges of coil a from coming off the running path.

4 is a crimping and cutting device, and two pairs of pinch rolls 29
, guide rail 30, feed roll 31, cutting @32
and punch hole sensors 33 before and after the feed roll 31.
．． It has an angle of 33°.

The pinch roll 28 is connected to the reducer 34 by the lower motor M6.
The rotation is transmitted and driven through the feed roll 3, which presses the coil a and the heat insulating material together and moves along the guide rail 30! The coil a is then fed into a winding machine after being cut at 32 and wound up as a heat insulating steel plate, that is, a product.

The feed roll 31 is driven by a motor M6 via a shaft 35 and a reduction gear 93B, and is driven by a punch hole sensor 3.
3 to reduce the rotational speed of the roll, and the cutting machine 32 works in conjunction with a punch hole sensor 33', and the sensor 33' detects the punch hole of the coil a whose running speed has decreased. This allows for cutting at more accurate locations. C1, C2, and C4 are all cylinders operated by hydraulic pressure or air, and are provided on both sides of the coil a, and rotate respective guide rails 37, 38, and 30, which support both side edges of the coil. It is designed to support both classes of coil a and guide its travel, or conversely to rotate so that coil a hangs between each guide rail.

When the coil a in front of each guide rail attachment part stops running or the running speed decreases, the subsequent coils a are prevented from stopping, and unreasonable tension is not applied to the coil a. For example, the guide 30 In this case, when the punch hole sensor 33 detects the hole and reduces the speed of the feed roll 31, the guide rail 30 opens and loosens the subsequent coil a, so that the rear coil a does not stop and the glue The coil a always runs at a constant speed inside the drying oven 15 of the attachment device 2. In addition, the guide rail 38 and the cylinder C2, and the guide rail 37 and the cylinder 〇+ reduce the influence of the temporary stop of the coil a in the part where the hole is punched when the punch flower bud hole device 9 is activated, respectively, on the other coil 6 parts before and after that. This is to prevent this from happening.

In the coil supply device 1, 39.39 indicates a phototube 40 provided below both ends of the guide rail 37 and a corresponding phototube 4! It is a pair of coil a detection device with a coil a attached to it, and when the loop of coil a hangs down greatly and blocks the optical path of the lowest phototube 40, the motor M1 stops and stops sending out the coil a, and the loop of coil a is suspended. When the loop of coil a is at the position of 40゛, the motor M1 rotates at low speed, and when the loop of coil a reaches the position of the highest photocell, motor M1 rotates at high speed, always keeping a certain amount of slack in coil a. The coil a is supplied in such a way that an excessive tensile force is not applied to the coil a.

Further, the counter B linked with the sensor 14 counts at the same time as the punch hole is detected by the sensor 14, and when the length of only the coil a, which is the eave part of the insulating steel plate, is counted, the cylinder 03 is activated to start gluing. start,
When the predetermined length of the glued part is counted, the cylinder 03
Stop the operation and finish gluing.

On the other hand, the counter C counts at the same time as the gluing starts, and when it counts the length between the gluing roller 12 and the cutter 27 position of the insulating material supply device 3, it starts supplying the insulating material, and then the counter C starts gluing. When the predetermined length of the attached portion is counted and the length between the gluing roller 12 and the cutter 27 position is counted, the heat insulating material is cut and the supply is stopped. When providing the eaves part at the rear end of the coil a, the predetermined length of the glued part is set by subtracting the eave part.

In this laminator, a predetermined length of a heat insulating steel plate as a product is set by a counter A, punch holes are punched in the coil a for each predetermined length, the chain holes are detected, and counters B and C are set based on this. The machine starts and stops gluing, glues to the desired length, and then cuts the insulation material to the appropriate length and sticks it on. Furthermore, when the insulation material is cut in response to a command from the counter C, the supply device 2 moves forward together with the coil a at the traveling speed of the coil a, while the insulation material itself stops running.

Furthermore, after the cutting is completed, the insulation material itself starts running in response to an instruction from the counter C to start supplying the insulation material, and after its tip is adhered to the glued part of the primary coil a, the device 3 moves backward. Return to original position. In addition, the cutting machine 32 detects the punched hole using the sensor 3.
After sensor 3 detects and the speed of coil a decreases, sensor 33°
The punched hole is detected and the coil a is accurately cut at the punched hole.

(Effects) The laminator according to the present invention is configured as described above, and in particular, the heat insulating material supply device is located above the coil sent out from the gluing device, is movable in parallel with the coil, and is small. When the insulation material is cut by the insulation material supply device, the insulation material is moved at the same speed as the coil, so even if the coil is running, the insulation material is moved while the insulation material supply device is moving at the same speed as the coil. The insulating material can be cut by stopping the cutting blade and the pinch roll, and the insulating material does not have wrinkles caused by pulling or loosening between the cutting blade and the pinch roll, which is the case with conventional methods, and a high-quality insulating steel plate can be obtained.

Therefore, the coil does not have to stop running to cut the insulation material, and can run continuously to produce insulating steel plates, improving efficiency.
% efficiency increases.

In addition, since there is no need to stop the machine to cut the insulation material, unlike conventional methods, when the coil is stopped running, the gluing surface on the coil in the drying oven of the gluing device becomes over-dry, causing adhesion. There will be no inconvenience caused.

Furthermore, as in the embodiment, a length measuring device and a counter are provided, which punch holes at predetermined lengths, operate the counter based on the punch holes, and start and stop gluing and cut the insulation material according to commands from the counter. By doing
It improves work efficiency and accuracy, and has the advantage of making it easy to adjust and change the position of gluing on the coil surface, and the position of gluing and the position of insulating material.
