It should be noted that supporting bodies 29, 29 are provided on the upper surface of the spreading table 2 on the side opposite to the base 4, and the distance between these supporting parts 29a, 29a is determined by the distance between the holding parts of each set of the conveying body 27. It should be shorter than that and equal to the separation distance of each set of supports 13.

About electric circuits As shown in Figure 3, a well-known microcomputer (microcomputer) has memory, calculation, and input/output functions.
In the input section of the MC, a rotating body 1 is arranged in relation to the shaft 7.
Selecting the angle sensor 20 for detecting the rotation angle position of 2 and 12 and the support body 13 of each set,
A microcomputer can check the type of raw material W stored there.
Various operation keys 30 and start switch 31 are connected to be stored in the MC, and the microcomputer MC

The microcomputer MC has two modes: "Mode I" for taking out the raw fabric W from the storage device 1 and placing it on the spreading table 2, and "Mode I" for returning the raw fabric W from the spreading table 2 to the storage device 1. ” and “mode” for exchanging the original fabric W on the spreading table 2 with another original fabric W in the storage device 1 are stored, and these modes can be selected using the operation keys 30. It is carried out with

A unique number (or symbol) is attached to each set of supports 13 of the storage device 1, and the number is recorded in advance in the microcomputer MC. Also, support 1
The microcomputer MC uses the operation key 30 to check the type or product number of all the original fabrics W stored in each set of 3.
You can now register as appropriate.

The software configuration of the microcomputer MC will be explained below along with the operation of the present invention.

First, it is assumed that all the raw fabrics W in the storage device 1 are registered in the microcomputer MC, and when taking out a predetermined raw fabric W from this state to the spreading table 2, select "Mode I" with the operation key 30. Next, after selecting a predetermined raw material W, the start switch 31 is turned on, and the following sequence starts.

That is, which set of supports 13 is located at the operating position indicated by the solid line in FIG. The amount of movement of the rotating body 12 up to the body 13 is calculated by the microcomputer MC, and the result is output as rotation angle information. In response to this, the motor 8 is activated, and the support body 13 storing the selected raw material W is moved and stopped at the above-mentioned operating position.

Next, the first electromagnetic solenoid 18 is turned on, which causes the flange 19b of the second electromagnetic solenoid 19 to advance directly above the empty space 14b of the lid body 14, and then interlocks with the rotation of the screw shaft 15 in one direction. Open/close arm 1
7 moves and stops from the upper inactive position to the lower active position, whereby the flange 19b of the second electromagnetic solenoid 19 enters into the cavity 14b of the lid body 14.

Therefore, when the second electromagnetic solenoid 19 is turned on from this state, the lid 14 moves to the position indicated by the two-dot chain line in FIG. 2 and opens the opening of the holding portion 3a. Thereafter, the screw shaft 15 is rotated in the opposite direction so that the flange 19b is extracted from the empty chamber 14b and returned to its original position, and then the first electromagnetic solenoid 18 and the second electromagnetic solenoid 19 are turned off.

Next, the motor 28 is driven to rotate the carrier 27 by a predetermined angle in the counterclockwise direction so that the left end in FIG. While moving from this position toward the base 4, the carrier 27 stops at a first position where the holding portion 27a of the conveyor 27 is located below the shaft Wa of the original fabric W, as shown in FIG. In addition, in connection with this, the carrier 2
The motor 28 rotates by a predetermined angle clockwise so that the left side of the roll 7 is tilted upward, and the shaft Wa of the original fabric W is picked up from the support body 13 at the working position in the storage section 27a.

Next, the motor 24 is driven to move the carriage 23 toward the spreading table 2, and when the carriage 23 reaches a neutral position, the motor 25 is driven to move the conveyor 27.
While turning 180 degrees, the carriage 23 further moves toward the spreading table 2, and as shown in FIG.
The axial rod Wa of the original fabric W held by the holder stops at a second position located directly above the support portions 29a, 29a of the fabric spreading table 2. Subsequently, the motor 28 is driven to move the carrier 27
rotates clockwise so that the right end of
transferred onto the Thereafter, the motor 24 is driven, and the carriage 23 is returned to the neutral position to complete this sea case.

When returning the original fabric W placed on the support part 29a of the fabric spreading table 2 to the storage device 1, select "mode" with the operation key 30 and then press the start switch 3.
If you turn on 1, the following sequence will start.

That is, after the carriage 23 is moved from the neutral position to the second position on the right side in FIG. 1 by the drive of the motor 24 and stopped, the transport body 18 is changed from the downward-rightward state to the upward-rightward state by the drive of the motor 28. As a result, the original web W is picked up as shown in FIG. 5, and from this state, the motor 24 is driven to move and stop the carriage 23 at the first position on the left side of FIG. The conveyor 27 is rotated 180° by the motor 25 at a neutral position midway. Subsequently, the motors 28 and 24 are sequentially driven to rotate the conveyor 27 counterclockwise to transfer the original web W to a predetermined support 13 and return the carriage 23 to the neutral position. In addition, the first and second electromagnetic solenoids 1
8 and 19 are turned on, the screw shaft 15 is driven to connect the flange 19b of the second electromagnetic solenoid 19 to the lid body 1.
4, the second electromagnetic solenoid 19 is turned off and the lid body 14 is moved to the position shown by the solid line in FIG.
4b and then remove the first electromagnetic solenoid 1.
8 is also turned off to end this sequence.

In addition, when exchanging a predetermined original fabric W with another original fabric W from a state in which a predetermined original fabric W is placed on the support portion 29a of the spread table by executing “Mode I”, use the operation key 30 to select “ mode" and newly select another web W, and then turn on the start switch. According to this mode, first, the raw web W on the spreading table 2 is stored in a predetermined support 13 of the storage device 1 according to the sequence of "Mode" described above, and then, according to the sequence of "Mode I". A newly selected original fabric W is taken out from the storage device 1 and placed on the support portion 29a of the fabric spreading table 2.

As described above, the present invention corresponds to a selected original fabric through a first drive device, a second drive device, and a third drive device whose drive is controlled in relation to information given from the outside by an operator. At the same time, the support of the storage device is moved and stopped at a specific working position, and the selected raw material is taken out from the support of the storage device to the support of the spreading table, or the raw material is transferred to a predetermined support of the storage device. Since it can be stored, raw fabric can be taken in and out of the spreading table from the storage device quickly and safely, and it does not require much manpower and does not cause worker fatigue, allowing long hours of work. Then,
This has the effect of significantly improving this type of workability.

In this embodiment, the original fabric W taken out from the storage device is placed on the support part 29a fixedly arranged on the spreading table 2. However, while holding the original fabric and reciprocating on the spreading table, The original fabric may be placed on a support portion of a fabric spreading device that unwraps the original fabric to a predetermined length and overlaps it on a fabric spreading table.
