Description

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

The object of this invention is to prevent the artificial leather wound on the raw fabric winding roll by reversing the drive motor even though the heating device has stopped driving during the process of massaging the artificial leather. To provide a method for kneading artificial leather, which prevents uneven kneading of the artificial leather by efficiently rewinding the length of the wound artificial leather onto a raw fabric delivery roll when the heating device is stopped. It is something.

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

In Figures 1 to 4, reference numeral 1 denotes the main body of a kneading device that automatically creases artificial leathers X1 and X2. A first web feed roll 5a and a second web feed roll 5b are installed on support arms 3a and 3b via a support shaft 4 to rotate seven times and to be detachable. The two pieces of artificial leather X1, X2 sent out from the feed rolls 5a, 5b are kept under constant tension via a plurality of feed rolls 6a to 6e and the weight 7, and the outer material Xa of each artificial leather X1, X2 is a feed-out supply roller mechanism 8 that overlaps each other so that they face inward; and a plurality of artificial leathers XI, X2 that are fed out in the polymerized state.
is heated to a constant temperature (for example, 12
A heating device 10 that heats the heated artificial leather X1,
A massaging roller 12 that moves in the left-right direction installed between la and 1Ib; a plurality of massaging rollers that move in the vertical and horizontal directions;
A kneading device 14 that performs kneading through 13a and 13b separates the kneaded artificial leathers X, X2 into respective artificial leathers X1 and X2, and winds up the original fabric while maintaining a constant tension. It is composed of a take-up and feed roll mechanism 16 that feeds out to rolls 15a and 15b.

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 rond of weight 7 is interposed between the feed rolls 6a 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. C. to 150.degree. 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 also includes a kneading roller 12 that moves in the left-right direction, and a movable kneading roller 1 that moves in the left-right direction by an air cylinder 17 and an eccentric drive shaft 18 above and below the kneading roller 12.
3a, 13b, both kneading rollers 12, 13
The linings xb of the heated artificial leathers X1 and X2 are rubbed against each other between a and 13b to create wrinkles.

Further, the winding and feeding roll mechanism 16 is connected to the kneading device 1
Two separation rollers 19a and 19b provided above 4
, a winding roll 20.21, a guide roll 22a,
22b, and these guide rolls 22a, 2
A weight 23 is interposed in the original fabric between 2b.

Further, 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. , are electrically connected via a clutch mechanism 25 to the rotational drive motor 24 of the original fabric winding rolls 15a, 15b.

In addition, in FIGS. 1 and 2, 26 indicates the kneading device 1.
4 is a drive motor, 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. It is a chain to make it happen.

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
1, X2), respectively, as shown in the figure.
With the outer material Xa of No. 2 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 rolls 15a and 15b.

From this state, a predetermined weight of ways }7, 23( weight bar).

These weights 7, 23 are used to always apply a constant tension to the artificial leathers XI, 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 feeding/feeding roller mechanism 8.

The artificial leather is heated to a certain temperature for a certain period of time.
Next, the kneading process for creating wrinkles 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 take-up rolls 20 and 21 and guide roll 22a.
, 22b to the respective raw fabric winding rolls 15at.
15b.

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 winding 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 winding of the web winding opening rolls 15a and tsb is started.

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

Next, when the driving of the heating device 10 is temporarily stopped,
Since the rotary drive motor 24 and the drive motor 26 continue to drive, the raw fabric that has been kneaded in an unheated state is wound around the raw fabric winding rolls 15a and 15b.

In this case, the raw fabric becomes uneven in the kneading process and its quality deteriorates, so it becomes necessary to heat and knead it again.

For this reason, the rotation drive motor 24 of the fabric winding rolls 15a, 15b and the first and second fabric feeding rolls 5 (not shown)
By reversing the drive motor connected to a and 5b, the length of the original fabric that was wound up without being heated is again transferred to the first and second
The original fabric is rewound onto the feed roll 5at5b and the same operation as described above is performed.

This allows uniform kneading to be performed.

In this invention, the wound artificial leather is kneaded again by reversing the rotary drive motor and the first drive motor when the heating device is stopped, so that the kneading process of the product is uniform and the quality is improved. It can always be kept in a constant state.

Moreover, since the operation is simple, anyone can easily perform the operation.
