Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for kneading artificial leather.

Conventionally, this type of kneading device has used a method in which artificial leather wound around a roll of raw material is sent out between a plurality of abacus-shaped kneading rollers and held therein to tighten the wrinkles.

However, with such conventional kneading equipment, it is extremely difficult to wrinkle thick artificial leather used for bags, shoes, etc., and it is also difficult to wrinkle multiple pieces of artificial leather at the same time. It was inefficient as it was not possible to attach

This invention was devised by focusing on such conventional problems, and its purpose is to be able to massage multiple pieces of artificial leather at the same time, and to process all types of artificial leather, regardless of whether they are thick or thin. An object of the present invention is to provide an artificial leather kneading method and apparatus that can wrinkle artificial leather continuously and efficiently.

Embodiments of the present invention will be described below based on the accompanying drawings.

In Figures 1 to 4, reference numeral 1 indicates the body of a kneading device that automatically wrinkles artificial leathers X1 and X2. A first web feed roll 5a and a second web feed roll 5b which are rotatably and detachably installed on support arms 3a and 3b via a support shaft 4, and the first and second web feed rolls. The two pieces of artificial leather X, X2 sent out from 5a and 5b are passed through a plurality of feed rolls 6a to 6e and a weight 7 while maintaining a constant tension, and the outer material Xa of each artificial leather X1 and X2 is A feed-out supply roller mechanism 8 that superimposes each other so as to face inward, and a plurality of artificial leathers X1 and X2 fed out in the polymerized state are heated to a certain temperature (for example, 120° C. to 120° C.) via a guide roller 9.
A heating device 10 that heats the heated artificial leathers X1 and X2 to a temperature of 50° C.
A kneading device 14 that performs kneading through a plurality of kneading rollers 13a, 13b that are installed between Ib and move in the vertical and horizontal directions and a kneading roller 12 that moves in the left and right directions, and Artificial leather X1, X2,
It is comprised of a winding roll mechanism 16 that separates the artificial leathers X1 and X2 and feeds them to the roll winding opening rolls 15a and 15b while maintaining a constant tension.

The first fabric feed roll 5a and the second fabric feed roll 5
b means that when the original fabrics of the artificial leathers X1 and X2 are sent out to the feed-out supply roller mechanism 8, the outer fabrics Xa of the artificial leathers X1 and X2 are placed so as to face inward, and A weight rod 70 is interposed between the feed rolls 5d and 5e to apply a constant tension to the artificial leathers X1 and X2.

Further, the heating device 10 is used to impart appropriate softness to the original fabric so that it can be efficiently kneaded.The heating temperature varies depending on the thickness of the original fabric, etc., but is generally 120°C as mentioned above. ~150° C. is set, and the temperature is controlled within a range of ±2% of this set temperature by a temperature control device (not shown).

The kneading device 14 is composed of a kneading roller 12 that moves in the left-right direction, and movable kneading rollers 13a and 13b that move in the up-down and left-right directions by an air cylinder 17 and an eccentric drive shaft 18 above and below the kneading roller 12. Massage roller 12
, 13a, 13b, the heated artificial leather X1,
The linings xb of No. 2 are rubbed against each other to create wrinkles.

Further, the winding and feeding roll mechanism 16 is connected to the kneading device 1
Two separation rollers l 9a , 1 provided above 4

2a+22b, this guide roll 22a
, Is there a wafer in the original fabric between 22b? A port 23 is provided.

In addition, limit switches LS1 and LS2 for detecting the upper and lower limit positions of the weights 23 are attached to the machine frame 2 on the side that supports the web take-up rolls 15a and 15b. is electrically connected via a clutch mechanism 25 to the rotary drive motor 24 of the original fabric winding o-ru i5a, 15b.

In addition, in FIGS. 1 and 2, 26 indicates the kneading device 14.
27 is a connecting rod that connects the drive motor 26 and the eccentric drive shaft 18, 28 is a cylinder that raises and lowers the massaging rollers 13a and 13b, and 29 is a cylinder that raises and lowers both massaging rollers 13a and 13b in synchronization. This is a chain for.

Next, the operation of the present invention constructed as described above will be explained.

First, as shown in FIG. 5, the respective raw fabrics (artificial leather
, X2), respectively, as shown in the figure.
With the outer material Xa facing inward, the material is passed through each roller and the device and wound around the rotation support shaft 30 of the material take-up roll 15at15b.

In such a state, a weight bar of a predetermined weight is placed between the artificial leather X1 between the feed rolls 5d and 5e of the feed supply roller mechanism 8 and the artificial leather X2 between the guide rolls 22a+22b. ).

These weights }7, 23 always apply a constant tension to the artificial leathers X1, X2, and when the weights 7, 23 are placed, the artificial leathers X1, X2
It's hanging down.

In such a state, the rotary drive motor 24 and the drive motor 2
6 and when the heating device 10 is activated, the artificial leathers X1 and X2 are fed into the heating device 10 in a superimposed state with the outer material Xa facing inward by the feed-out supply roller mechanism 8.

The artificial leather is heated to a certain temperature for a certain period of time.
Next, wrinkled kneading is performed in the kneading device 14 for a predetermined period of time.

Two pieces of artificial leather X1, X treated in this way
2 are then separated by separation rollers 19a and 19b, respectively, and are then separated by winding opening rolls 20 and 21 and guide rolls 22.
a, 22b to the respective raw fabric winding rolls 1 to 5.
It is wound up by a, 1 5 b.

At this time, since the winding speed of the artificial leathers X1 and X2 wound by the raw fabric winding rolls 15a and 15b is faster than the speed at which they are sent out from the kneading device 14, the artificial leather
1 and X2, the weight 23 is pulled upward.

Then, the limit switch LS1 installed at the upper end of the machine frame 2
One end of the weight 23 comes into contact with the material roll 15.
The clutch mechanism 25 (electromagnetic clutch) connecting the rotational support shaft 30 of the rollers a, 15b and the rotational drive motor 24 is disconnected, and the winding of the original fabric winding rolls 15a, 15b is temporarily stopped.

On the other hand, the winding and feeding roll mechanism 1 is
6 and the kneading device 14 are driven, so that the artificial leathers X1 and X2 are sent out one after another after being kneaded.

When the artificial leathers X1 and X2 are sent out, the weight 230
Due to the weight, the artificial leathers X1 and X2 sag downward,
When the weight 23 comes into contact with the lower limit switch LS2, the clutch mechanism 25 is engaged and the winding of the original fabric winding rolls 15a, 15b is started.

By repeating these operations in sequence,
The raw fabric can be efficiently kneaded.

As described above, the present invention transfers a plurality of original fabrics wound around a plurality of original fabric feeding rolls to a plurality of original fabrics through a feeding supply roller mechanism → heating device → kneading device → winding and feeding roll mechanism. Since it is wound up using a winding roll, multiple pieces of artificial leather can be efficiently and beautifully kneaded, and it has the effect of being applicable to all kinds of products regardless of the thickness of the artificial leather.

Moreover, if several such devices are installed and continuous processing is performed, even more efficient kneading processing can be performed.
