Abstract

PURPOSE:To mechanically efficiently set a rolled material on an extending machine by providing two longitudinal rolls for receiving a rolled material with a space, providing a means for selectively driving one of rolls, and providing respective brake means for the rolls. CONSTITUTION:On the body of an extending machine capable of longitudinally reciprocating on a table, two longitudinal rolls 10, 11 for receiving a rolled material 5 which are horizontally disposed with the shaft centers being turned in lateral directions orthogonal to the moving direction of the extending machine are provided with a longitudinal space. A means for selectively operating at least one roll 1 of the two rolls 10, 11 is provided, and respective brake means for the rolls 10, 11 are provided. The drive and stop of the two longitudinal rolls 10, 11 are operated to hang the cloth 5a of the rolled material 5 downward through between the two rolls 10, 11 followed by feeding, whereby the set of the roll to the extending machine is mechanically efficiently performed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a fabric spreading machine that feeds out a roll of fabric (cloth) into required lengths and cuts or folds the fabric.

2. Description of the Related Art In this type of conventional fabric spreading machine, a fabric receiving device is provided on the main body of the fabric for spreading. It is configured to rotate in one direction and feed the dough forward,
is known.

Problems to be Solved by the Invention In such a conventional spreading machine, it is possible to spread 5 pieces of fabric a! When setting the fabric, the fabric is initially pulled so that the edge of the fabric is caught on the feed roller at the front end of the spreading machine. There was a problem in that it took a lot of time to complete the process.

The present invention has been made to solve these problems, and an object of the present invention is to provide a fabric spreading machine that enables automatic setting with a simple configuration when placing and setting a fabric on a full fabric spreading machine.

Means for Solving Section M To solve this problem, the present invention is on the table! !
7I later? jlS On a freely movable cloth-spreading main body, the axis is oriented horizontally in the left-right direction perpendicular to the moving direction of the cloth-spreading machine, and two rolls, front and back, that receive the roll-shaped cloth are placed horizontally, with a gap in the front and back. Be prepared.

A means for selectively driving at least one of the two rolls is provided, a brake means for each of these rolls is provided, and a sensor is provided for detecting the presence of the fabric hanging between the two rolls. The settings are as follows.

Function: With this configuration, the fabric is set in the spreading machine mechanically and efficiently by operating the drive and stop of the two front and rear rolls to let the fabric hang down from between the two wooden rolls, and then sending it out. be able to.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings.

In Figures 1 to 3, reference numeral 1 denotes a spreading machine that can move back and forth on a backward moving table 2. On the main body 3 of this spreading machine 1, there is a device 4 for holding cloth at the rear end. A feed roller 6 is provided on the front end side for feeding out the fabric 5a drawn from the fabric 5 on the fabric receiving device 14 downward. Reference numeral 7 denotes a belt conveyor in which the cloth holder is interposed between the device 4 and the feed roller 6;
It is located close to the rear of the Reference numeral 8 designates a pitcher provided at the lower part of the front end side of the main body 3 of the spreading machine, and reference numeral 9 designates a cover that covers the upper ends of the apparatus 4 at the front and rear thereof.

By the way, the cloth support device 4 has two rolls 10.1, front and rear, which receive the roll-shaped cloth 5 and are arranged horizontally with their axes oriented in the left-right direction perpendicular to the traveling direction of the spreading machine 1.
1, and a roll 10.1 at a position inclined upward from each roll 10.11 before and after each roll 10.11.
Auxiliary rolls 12a and 1 are provided in parallel with 11, two each.
2b and 13a, 13b and the two rolls 1
It consists of a motor 14 that drives 0.11. More specifically, the two rolls 10.11 are placed between the front and back.
The motor 14Fi is located above the center between the two wooden rolls 10.11 and
1 is configured to transmit the driving force of the motor 14 to the next sprocket via a chain, and a one-way clutch 15.16 is interposed between each sprocket and each roll 10.11. When the driving force from the motor 14 is transmitted to one roll 11 or 1], the driving force from the motor 14 is not transmitted to the other roll 11 or 1; It is configured to idle. A brake means is provided corresponding to the ninth roll 10.11. 17a and 17b are a pair of sensors that detect when the fabric 5a passes below between the two rolls 10.11.

In the above configuration, the setting operation of the fabric holder after placing the fabric 5 on the device 4 will be explained. When setting the fabric 5 on the outer side of the fabric spreading machine 1vC, first, as shown in the third section, the fabric 5 is placed on the device 4. is placed on two rolls 10゜, and the rear roll 11 is driven clockwise as shown in Fig. 3, so that the front roll IO is in a idling state.

In this state, the cloth 5 rotates on the rolls 10 and 11, and when the fabric 5a at the starting end of the cloth 5 is positioned a considerable length behind the rear roll 11, the brake is applied to the front row/l'IO. and stop it at empty kh1. At this time, the rear roll 11 is rotating, so as shown in FIG.
Fabric 5 up to the starting end located behind the roll lO of i
a slackens between the two rolls 10.11 and then Fig. 3 1
After releasing the brake on the front roll 10 as shown in c), by continuing to drive the rear roll 11, the fabric 5a at the starting end of the fabric 5 is transferred to the rear roll 11 as shown in FIG. 3+DI. It moves away from the body and hangs downward. At this time, the fabric 5a blocks the space between the pair of sensors 17a and 17b,
From this state, the cloth 5 further rotates to the third (2) [El
As shown in FIG.
．． 17b. This results in
The pair of sensors 17a and 17b confirm the existence of the starting end of the fabric 5a, and after the front roll 10 has stopped, the front roll 10 is then driven counterclockwise in FIG. to be left idle. As a result, the cloth 5a is fed out while the cloth 5 is rotated clockwise and placed on the belt conveyor 7, and the cloth 5a is moved forward by the drive of the belt conveyor 7 and moved to the feed row on the front end side.
The goods are sent downward from 9-6. In this way, the fabric 5 is set on the spreading machine 1 rather than manually as in the past.

It can be done mechanically and efficiently.

By the way, in the operation explanatory diagram shown in Figure 3-fFl, the cloth 5 on the outer side is automatically set! ! However, when automatically setting the inner fabric, the front and rear rows A' 10
．． The operation in step 11 may be reversed to that shown in FIG. 3 above. Further, in the above explanation of the operation, one of the rows A/ is driven and the other roll is idled, but both rolls may be driven simultaneously. Further, drive sources for each roll may be provided separately. Note that the auxiliary rolls 12a, 12b and 13a, 13b ij
It is provided to prevent the cloth 5 from falling off the rolls 10 and 11, and may also be driven if necessary.

Effects of the Invention As described above, according to the present invention, when placing and setting the fabric on a spreading machine, it is possible to efficiently set the fabric on a spreading machine mechanically rather than manually, as in the conventional method, and moreover, it is possible to set the fabric on a spreading machine efficiently, and moreover, the roll that receives the fabric can be used. The structure can be simplified and provided at low cost by simply devising the drive operation.
