Description

[Detailed Description of the Invention] The present invention relates to a fabric spreading machine that is capable of spreading various fabrics with a single model.

Conventional spreading machines have different configurations depending on the type of fabric used.

For example, different models are used for open rolls and tubular rolls, and the same applies for rolls that are highly malleable or those that are likely to run, and those that are not.

Therefore, in the past, there were problems such as the large financial burden of having to prepare various spreading machines suitable for each application and the need for a large installation space, and the problem that the operating rate of each model had to be reduced. was there.

By the way, as a well-known type of spreading machine, a main body of the spreading machine is installed on the upper surface of a horizontal workbench so as to be able to move back and forth, and a pair of machines are installed at the front of the main body of the spreading machine to feed out the original fabric in a meandering manner. There is one that is provided with a roll for feeding out the original fabric, and is provided with an original fabric support part that suspends and supports the rolled original fabric at the rear.

This method applies a certain amount of tension when passing the raw material through the feed roll, so it can generally only be used for open fabrics with low malleability.

The present invention is an improvement on such a system, and it can reliably spread even tubular-shaped raw fabrics or raw fabrics that are highly malleable and may cause runs through a safe route without applying tension. The purpose of the present invention is to provide a spreading machine that can be used in a wide range of applications, that is, can be highly efficient.

An embodiment of the present invention will be described below with reference to the drawings.

A spreading machine main body 2 is placed on the upper surface of a horizontal workbench 1 so as to be movable back and forth via running wheels 3.

This spreader main body 2 has a pair of rotationally driven rolls 4 at the front, and a pair of leg-shaped rolls 5 at the rear. A plurality of guide rolls 6ay6b are rotatably disposed in the section.

A horizontal workpiece placement surface 7 is provided in front of the workpiece support part 5 of the spreader main body 2, and a dome-shaped guide plate 8 is provided above the feed roll 4 and directly above the guide rolls 6a and 6b. and a pair of auxiliary feed rolls 9 and 10 which are positioned before and after the guide plate 8 and are driven to rotate synchronously with each other are provided, respectively.

In addition, there is a pair of parallel rods 1 on the lower side of the front auxiliary feeding roll 9.
1 is rotatably mounted so that its parallel rods 11 can be rearranged up and down or back and forth.

Furthermore, a pitcher 13 shown in FIG. 1, a feed roll 14 shown in FIG. 2, a cutter device (not shown), or the like is selectively attached to the lower end of the main body 2 of the spreader.

On the other hand, a catcher 15 shown in FIG. 1 is attached to a predetermined position on the upper surface of the workbench 1, for example at the front end, in correspondence with the pitcher 13.

The feed roll 4 and each of the auxiliary feed rolls 9 and 10 are driven to rotate in a predetermined manner in relation to the traveling of the main body 2 of the spreading machine.

That is, as shown in FIG. 4, for example, the drive device has a main motor 16 for driving the main body of the spreading machine, and an auxiliary motor 17 independent of this.

The main motor 16 connects the running wheels 3 to a connecting shaft 18 and a bell H9.
, 20, and the spreading machine main body 2 is connected by forward and reverse rotation.
It is designed to operate reciprocatingly.

Then, the rotation of the connecting shaft 19 is converted into one direction and extracted by a one-way box 22 via a belt 21. The motor is connected to the motor through a speed reducer 24, a belt 25, an electromagnetic clutch 26, and a timing belt 27.

The feed roll 4 is connected to the drive shaft 23 via gears 28, 29, and the auxiliary feed rolls 9, 10 are connected via belts 30, 31, respectively.

During the reciprocating movement of the main body 2 of the spreading machine, the feed roll 4 and the auxiliary feed roll 9° 10 are rotated in synchronization with each operation.
The rolls 4, 9 and 10 are rotated in one direction, that is, in the unwinding direction, and when the spreader main body 2 stops at a turning point, the electromagnetic clutch 26 is disengaged and the rolls 4, 9 and 10 are freed.

Note that an external operation bundle 32 is connected to the reducer 24,
This allows the rotational speed of each roll 4, 9, 10 to be adjusted.

- The auxiliary motor 17 is connected to the drive shaft 23 via a chain lever 33, and is made free from the main motor 16 by the electromagnetic clutch 26, so that the auxiliary motor 17 can drive the drive shaft 23 when necessary. There is.

With such a configuration, the spreading work is performed by, for example, as shown in FIG. In the first mode of feeding, as shown in FIG. This can be done in two ways: a second mode in which a slight tension is applied between 11 and the tip is fed out with almost no meandering;

Therefore, the former route is used for relatively strong raw fabrics with low malleability, and the latter route is used for knitted O-17 fabrics, knitted fabrics, and tubular fabrics for jersey, respectively. In this way, it is possible to use it properly depending on the purpose.

Therefore, it is very convenient because it can perform multi-purpose spreading with a single model, and of course it can improve operating efficiency.
This also eliminates the economic and space waste that occurs when installing multiple models.
