Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial fields of application Papers, am sheets, plastic films and sheets, and laminated composites and coated products thereof.

The present invention relates to an apparatus and a processing method for simultaneously rolling, softening or wrinkling a plurality of sheet-like materials such as artificial leather.

BACKGROUND OF THE INVENTION Conventionally, with regard to rolling processing apparatuses and processing methods thereof, there have been known ones that process two sheet-like objects, whether it is a single sheet or a plurality of sheets, when binding sheet-like objects.

(c) Problems to be solved by the invention Conventionally, multiple sheets (
The sheet-like material rolling processing device and its processing method described in 2) are for artificial leather based on fiber sheets, and during the rolling process, the sheet-like material gradually shifts to the mated state. This caused problems with continuous operation as it was shifted to one side in the width direction.

Even more so, when the workpiece is made of many pieces or includes plastic films or sheets that easily slip off.
There was a misalignment between the gripping or holding of the gripping tool and the alignment during the rubbing process, making it impossible to perform the appropriate rubbing process.

Heating before and after specimen processing is simply a heating method using far infrared rays, and cannot heat the inside of a sheet-like object.If there are three sheets, there is no heating effect, and cooling is not possible. Since it is a cooling method, there was a problem in terms of stabilizing wrinkle formation. In other words, the mechanical elements and processing method for the two-way processing cannot be applied to a plurality of sheet-like objects.

(ii) Means for solving the problem Concerning the holding device or gripping device for the sheet-like material, and the rolling mechanism, in accordance with Japanese Patent Publication No. 59-6953, the transportation of the sheet-like material, that is, from unwinding to winding, is carried out at each stage. The mechanical elements are equipped with a brake, a speed control device, a compensator for tension and speed adjustment, a meandering position adjuster, etc., and these mechanical elements can be controlled independently, and each mechanical element can be operated simultaneously as a line. I made it.

In order to correct the unevenness caused by "misalignment" of the sheet material during the rolling process, the "misalignment" is restored to its original position by making the gripping tool for the workpiece workable in the forward and reverse directions in the rolling mechanism. This is what I did.

Heating or cooling is an auxiliary means to the rolling process.

The matching machine and kneading machine are controlled by steam or gas such as air.
The back side of the sheet-like material and the inside of the matched structure were exposed as much as possible.

(E) For production Braking, speed, etc. control devices are installed in the front of the kneading machine.

By installing a folding sweater and a meandering position adjusting machine, the sheet-like material is aligned by the aligning machine, held, transferred to the kneading machine, and fed.

The rolling mechanism of the rolling machine has a gripping tool that can be rotated in forward and reverse directions to prevent misalignment of the sheet material during rolling.

The rear device of the rolling section is also equipped with the same mechanical elements as the front device to separate multiple sheet-like materials and finish each processed product with neat edges on both sides of each width. It will be done.

In addition, even if a single sheet slips off, or has weak physical strength and is easily damaged, and cannot be rolled, it can be made into a Sand Germany shape, reinforced with three sheets, or four sheets alternately put together. By making it into a sandwich shape, it can be rubbed.

Alternatively, if the sheet-like material or multiple materials are likely to cause trouble during transportation, the sheet-like material can be transported and fed from the upper part of a vertical massaging machine to perform the massaging process. can be easily achieved.

As an auxiliary means for rolling, heating to soften the sheet-like material can be done by supplying and discharging gas to instantly heat both the front and back sides and the inside under the same conditions, and also to process the material in the opposite direction in the same way. By cooling the product, it is possible to stabilize the wrinkled state of the inner and outer sheet-like material.

(to) Example of implementation Example 1 (kneading processing device) An example of a kneading device will be explained with reference to the drawings.

FIG. 1 is a simplified side view of the kneading device.

The direction in which the sheet-like material is transported from the bottom to the top of the kneading machine is defined as the forward direction, but in the embodiment, it is the reverse direction, so one machine element will be explained accordingly.

Q2a) 02υQ3c) is a winding machine.

The circular guide roll without any reference numeral is a general guide roll (this can be provided at any location).

Next, two or more mechanical elements will be described.

The unwinding machine (Ia) (lb) (lc) # Yorj winding machine Q2a) (12bl Q3c) can be used with forward and reverse drive, respectively, but it is equipped with a controller and itself has a tension (torque) I controlled it. It can be linked with a compensator or EPC. The model is 1 axis,
2 axes.

An automatic machine such as a 3-axis talent type is used.

Of course, the folding loading type and the shaking loading type, which are often used in fiber sheet-related applications, can also be used together with the cross guider.

A compensator, for example (Al), is also called a 7-kiyum letter, and is shown in a simplified diagram.

Equipped with a detection head (amplifier) and an electro-pneumatic converter (which converts electrical signals into pneumatic signals), it can adjust the transport speed of sheet materials,
Tension can be adjusted.

However, in the case of the 1-winder side (for example, A4°A in Fig. 1)
5. As for A6), there are cases where the control function of the automatic winding machine is sufficient, so in that case, it is not necessary to incorporate it into the line.

EPC is used when feeding multiple sheet-like materials to the rolling machine 0 or when winding up the processed products.
It is necessary to align the It is (air, photoelectric, etc.)
It consists of a detection head, an end position adjuster, etc., and the embodiment is of an S-type winding roll type. In addition, an offset type (in the vertical direction) is also used.

Guide (guide) a-le, e.g. (4a) (4b)
(4c) is located near the aligning machine to facilitate feeding of each sheet-like material to the aligning machine. and 1 for example (9a)
(9b) and (9c) are located on the winding side of the processed product and separate each sheet-like material from each other.

Consistency S! is located near the outside of the rolling machine (on the entrance/exit side of the sheet-like material), and the sheet-like materials whose widths are aligned (aligned) are combined (aligned) through the EPC guide roll.
It is composed of a pair of rolls, and the mutual nip pressure of the rolls is adjusted.
In addition, the sheet-like material is operated to maintain an appropriate (predetermined) distance, or in other words, tension, depending on the tension of the sheet-like material due to the operation of the rolling machine. Regarding this operation, one way is to rotate it in conjunction with a compensator (for example, AI), and the other way is to move the compensator itself up and down by an air cylinder (sometimes using hydraulic pressure, springs, etc.), etc. It is something. and.

Even if the roles themselves are not parallel pairs.

A plurality of rolls capable of acting in this manner may be arranged, and the rolls may be smooth rolls, rough rolls, metal rolls, rubber-wrapped rolls, or the like.

The action of this aligning machine is to combine the two separated sheet materials, and also to sway back and forth and left and right during the rolling process.
It stabilizes the tilt and tension.

However, (5c) and (5d) may be omitted depending on the case.

Next, the kneading machine will be explained with reference to FIGS. 2 and 3.

FIG. 2 is a plan view of the gripper (CI), and FIG. 3 is a partially cutaway view of the drive transmission device.

The kneading machine 0 is equipped with a plurality of gripping machines composed of gripping tools.

(6a) is a fixed grip, and (6b) is a movable grip.

■ is the gripper frame, 121) is the connecting shaft, ■
The symbol is the coupling, and the symbol in Figure 3 is the drive transmission crankshaft.

(To) is an air cylinder, which is fixed at ■. The main element is the crankshaft that transmits the operation of the engine to (6b).

Regarding the mechanism of the mechanical elements of each of these parts, in FIG.
) and the movable grip (6b).

Here, F cylinder (to) and crank shirt)
121i) to move the movable gripping tool (6b) to the side of the fixed gripping tool (6) and grip a plurality of sheet-like objects.

That is, to hold or hold ((C2) (C3)
(Although it has a similar mechanism, it is not shown).

Next, for the rolling process, when the motor is driven, the drive is caused by the drive transmission crankshaft shown in Fig. 3 rotating the coupling tool connected to it, which is then transferred from the coupling shaft of the company as shown in Fig. 2. The grip & machine frame (2) is horizontally swung according to the locus in the rotational direction corresponding to the eccentricity of the drive transmission of the coupling tool.

For example, the position of the connecting shaft ■ in the connecting tool ■ (CI
) In the gripping machine of (C2) (and (C3)),
If you shift it on the vertical line, (C1) (C2
), the mode is as shown in FIG.

Its position on the vertical line can be set arbitrarily.

Fig. 4 is a partially cutaway diagram showing an embodiment of the rolling process, and 1), 2), and 3) are the workpieces.
It is a sheet-like product. In FIG. 4, a sheet-like object is gripped by gripping tools (6a), (6b), and (7a) and (7b), respectively.

Next, reduce the distance between the grippers (C1) and (C2) (C
I ) and sheet-like materials ■1) C2) [Yes]
3) takes a deformed S-shape as shown in Figure 4, and when forward and reverse rotational drive is transmitted in the same direction to each gripping machine (gripping machine frame) via the connector ■, the fourth In the state shown in the figure, the kneading process is performed as if it were being kneaded by hand.

The gripping tool is made of metal, has an iron core covered with plastic, rubber, or a porous material thereof, or
A device covered with a fiber sheet is used to grip, ie clamp, or hold a sheet-like object, and the strength of the grip can be adjusted, and the mutual spacing between the grippers can also be adjusted. .

The forward and reverse directions of the drive transmission of the gripper are controlled by time or rotational speed.

Note that proportional control is also possible.

The vertical movement of the gripping machine is done individually for each gripping machine.

If the drive transmission mechanism including the round coupling shaft in Fig. 3, the coupling device in ■, the drive transmission crankshaft in (7) to swing at a fixed position, upper (CI),
Each of the lower (C3) grippers is brought close to and separated from the (C2) gripper.

If the gripping device consists of two devices, one should be in a predetermined position and the others should be close together or separated, or close to each other or separated.
It can also be isolated.

If the number of grippers installed is an odd number, or an even number, it is possible to use a mechanism of one or more as appropriate.

The gripping process is carried out without interruption even when the gripping machine moves up and down.
The position at which the sheet-like object is released from the grip is set when the gripping tools approach each other, but the position at which the gripping tools are separated can be set as appropriate. When the gripper releases the sheet, it transports the sheet.

Then, the gripping tool grips (pinches or holds) the sheet-like object only when the gripping device is separated.

1) ■2) ■3) of the heating/cooling machine in Figure 1.

It is linked to the operation of the equipment line, and its temperature and air volume can be automatically controlled, and heating and cooling are performed using steam, hot air, cold air, etc.

The action points are divided into three sections as shown in the figure. Heating or cooling differs depending on the constituent material of the sheet material, but 1) usually on the supply side, i.e. preheating (pretreatment), 2) heating (or cooling), and 3) on the exit side of the processed product. is allowed to cool down.

The above is an example of the implementation, in which sheet-like materials are transported and supplied mainly through a rolling machine.

Although the arrangement and order of each mechanical element in the rolling process, take-up, and transfer, and the driving relationships such as the omission of two parts, the addition, and the drive for transfer, can be selected arbitrarily, The at least essential requirements for processing equipment are speed adjustment, meandering position adjustment, alignment of sheet materials,
It consists of mechanical elements that move the gripping machine vertically and horizontally, as well as perform forward and reverse operations.Even when heating or cooling is done electrically, it is used to heat sheet-like objects. , the cooling medium is a gas.

In addition, each mechanical element can be operated and controlled independently, and the overall operation of the device as a series of lines can be controlled.

Example 2 (Kneading method) An example of a kneading method will first be described in relation to the kneading device shown in FIG.

(1a) is wrapped with a layer of artificial leather having a thickness of about Q and 7 mw with the outer skin facing outward, and cib) is wrapped with a basis weight (weight) of about 50 mw.
Wrap 97 d of Western paper, and (Ic) polypropylene 0PP with a thickness of about 20 microns on the Western paper of 40 g/- in basis weight)
A film laminate is rolled up, a guiding cloth or guiding paper is attached to each of the pieces, and the guiding cloth or guiding paper is set in the winding machine Q2a) Q2bl Q2c) in the state shown in FIG.

The main motor is driven and the transfer speed is adjusted by finely adjusting each mechanical element.

After doing this, the sheet material is unrolled.

Meandering adjustment of the widthwise end of each sheet is performed using EPC,
Predetermined appropriate tension (AI) (A2) (A3
) while adjusting the sheet material with the fume vent sweater, transport it over each guide roll (4a), (4b), and (4c), straighten the widthwise edges of each sheet, and feed it to the aligning machine in a free state. , so the distance between the rolls of the matching machine (5a) (5
b) Narrow down.

Next, in each gripper (CI) (C2) (C3), the movable m −'A tool (6b) (7b) (8b)
Move the sheet and clamp or hold the sheet by narrowing the mutual distance with the fixed gripping tool (6ωcIω(8a) from the state shown in Figure 1.(5c) From the aligning machine (5d) to the winding machine 0
Between 2ωQ2b) and Q2c), the tension, meandering, speed, etc. are adjusted in the same manner as when transporting a sheet from a winder.

Make the 4 grips (C2) swing in a predetermined position.

The upper position gripper (C1) and the four lower position grippers (
C3) is brought close to (C2) as shown in Figure 4.

At that time, the sheet-like materials are each pulled, but compensators (Al to A6) and alignment machines (Ba) (5b
) (5c) (H, etc., or when (5c) (5d) is omitted, guide roll (9a) (9b) (9c
) and the compensator, the tension is adjusted. Then, it is rubbed repeatedly. During this time, the transport of sheet materials has been temporarily stopped. After a predetermined time, the holding of the sheet-like object by the gripper is released, and the seed-like object is transferred.

This operation is repeated to perform continuous rolling.

The above is an example of implementation, but if the Western paper in (lb) is used in a single piece, it will be damaged and cannot be rolled. If this is done as in the example, it will also serve as reinforcement and can be rubbed. In addition, even in the case of a combination of sheet-like objects as in the example (in the case of two pieces of artificial leather), regardless of the difference in the shape and material of the gripping tool, or the type of cover of the gripping tool, the sheet-like object of the gripping tool Although it depends on the holding or clamping force, as the kneading operation continues, the holding position shifts and the kneading process becomes impossible over time.

In particular, plastic films and laminates thereof have low frictional resistance and can easily slip off.

Therefore, the swinging direction of the gripper is controlled by a timer or a p-tally counter to restore the original position.

Normally, the forward and reverse conditions are the same, but if there is a deviation, confirm it in advance through a preliminary test and set it.

The gripping stroke or pressure of the grippers, the mutual spacing (stroke) of the grippers, the eccentricity of the mutual positions of the grippers, etc.
Test it beforehand and decide. These influence the wrinkled shape.

Continuous operation of rolling of multiple sheets is possible by linking the operation of the rolling machine 0 as described above with other machine elements, alignment machine, meandering position adjustment machine, and compensator (other control machines). You will be able to do this.

In particular, sheet-like materials that are easily damaged, easily slip off, or difficult to be rolled are easily aligned and prevented from slipping when fed from the upper part of the rolling machine 0 as in the embodiment.

On the other hand, artificial leathers (vinyl leather, synthetic leather 2, artificial leather), etc. can be rubbed even if they are fed from the lower part of the rolling machine 0.

In the embodiment, a heating/cooling machine is not used, but it may be used depending on the material and rigidity of the sheet-like object.

In addition, which side of the sheet-like material should be aligned can be arbitrarily determined depending on the state in which it is wound on the two unwinders and how it is set, and the direction of transport may be changed as appropriate for operational reasons. .

If any trouble occurs during operation, the conveyance of the sheet material is stopped at that point, feedback is immediately given, and the sheet material is conveyed again for processing.

(G) Effects of the invention Arrange the edges in the width direction of the sheet material to be rubbed, adjust and align the tension, operate the rocking motion of the rolling process in forward and reverse directions, and adjust the strength of the tension accordingly. By creating a device equipped with such mechanical elements and processing using the device.

The present invention can be used to process not only a single sheet, but also two or three sheet-like materials, even if the sheet-like material cannot be rubbed with a single sheet, or even with a single sheet or multiple sheets that easily slip off and cannot be rolled. It is now possible to process multiple pieces such as 1 piece, 4 pieces, etc.

It can be softened and wrinkled.

It will be possible to improve production efficiency.
