[Detailed description of the invention] (Field of industrial application) The present invention relates to a spreading machine that can perform a predetermined spreading action by reciprocating with a stroke depending on the spreading length. The present invention relates to a spreading machine for suitably supplying a rolled raw fabric to a machine body.

(Prior Art) An example of a device for supplying a roll-shaped original fabric to the main body of a spreading machine is the one disclosed in Japanese Utility Model Publication No. 60-6040. This item is shown in Figures 6 and 7.
As shown in the figure, the spreading machine main body A and the original fabric supply device B
The original fabric supply device B includes an original fabric mounting table 101 on which the rolled original fabric 100 is placed so as to be able to roll toward the side of the main body A of the spreading machine, and a fabric mounting table 101 on both sides of this mounting table 101. A pair of side frames 102 provided, and a rolled original fabric 10 on the original fabric mounting base 101 provided at the front edge of each of these side frames 102 on the original fabric mounting base 101 side.
A lifting guide surface 104 that raises the support shaft 103 of the 0 obliquely forward, and a roll that is provided on the upper edge of each of the side frames 102 so as to be tilted forward and downward, and is sent by the lifting guide surface 104. A transfer guide surface 105 that supports the support shaft 103 of the shaped original fabric 100 so as to be able to roll forward, and a roll-shaped transfer guide surface 105 that is provided substantially vertically at the front edge of each side frame 102 and that has rolled on the transfer guide surface 105. A descending guide surface 106 that lowers the support shaft 103 of the raw fabric 100 along the vertical direction, and a lowering guide surface 106 that lowers the support shaft 103 of the roll-shaped raw fabric 100 along the respective guide surfaces 104, 105, 106 with claws 107, 10.
Chains 108, 113 conveying via 7';
The spreading machine main body A is engaged with the rail 110 laid on the spreading table 109, and the traveling wheels 111 are capable of moving in the same direction. The roll-shaped raw fabric 1 descends along the descending guide surface 106 with the descending guide surface 106 aligned with the anti-support portion 112.
00 support shaft 103 is passed to the original fabric support section 112.

(Problem to be solved by the invention) However, in such a conventional device, the chain 10 is attached to each guide surface 104, 105, 106.
8 and 113 are arranged side by side, so that the support shaft 103 of the roll-shaped original fabric 100 is passed to the original fabric support part 112 so as not to generate an impact. There were problems in that the configuration was very complicated and the device B itself was also very large. In particular, when the device B becomes larger, the length of the spreading table 109 is also affected, and the length of this table 109 must be increased, so depending on the location where the spreading machine is installed, the space may be limited. There was a problem in that the spreading machine could not be installed due to restrictions or obstacles in the installation location.

The present invention was devised in view of these circumstances, and its purpose is to achieve the advantages of the conventional device described above, namely, to enable two people to handle both ends of the support shaft of a heavy rolled material. The difficulty of having to lift the main body of the spreading machine to the raw material supplying position (usually 120 cm or more and higher than a human arm) while holding it;
There is the trouble of having to return the main body of the spreading machine to its maximum stroke point each time a rolled material is supplied to feed the material, and the need to transfer the support shaft of the rolled material to the material support part of the main body of the spreading machine. It is an object of the present invention to provide a fabric spreading machine that not only eliminates the inconvenience of damage to the support shaft or the fabric support part due to the occurrence of shocks, but also allows the fabric feeding device portion to be significantly miniaturized. be.

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, the spreading machine of the present invention is provided with a raw fabric feeding device that is moved together with the main body of the spreading machine at the rear of the main body of the spreading machine. This raw fabric supply device includes a pair of side frames on both sides, and a lift provided on each side frame to convey the supporting shaft of the rolled raw fabric diagonally upward toward the main body of the fabric spreading machine through claws. , a downwardly sloping guide surface that rolls the support shaft of the rolled material fed by this lift from the top dead center position of the lift toward the main body of the spreader, and a support shaft on this guide surface. It is equipped with an unraveling roller having an elastic member on the outer periphery, which blocks the rolling roll-shaped original fabric.

(Function) According to the above configuration, the raw fabric supply device is integrally provided at the rear of the fabric spreading machine body so as to be movable together with the fabric spreading machine body.
There is no need to provide a stand for stably placing the sheet on the sheet spreading table, and the sheet feeding device can be significantly downsized. In addition, in the case of this fabric supply device, if the support shaft of the rolled fabric is brought to the lift via the claw set at the bottom, and then the rolled fabric is conveyed diagonally upward by this lift, the rolled fabric can be The supporting shaft of the original fabric reaches the top dead center position of the lift. The support shaft of the roll-shaped original fabric that has reached the top dead center position separates from the pawl and moves to the guide surface, and rolls toward the main body of the fabric spreading machine due to the downward inclination of this guide surface. The rolled material whose support shaft is rolled on this guide surface collides with the unraveling roller, but since the unraveling roller has an elastic member on its outer periphery, the impact force is absorbed. As a result, the roll-shaped original fabric is set at the original fabric supply position relative to the main body of the spreading machine.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 5.

The protrusions at both ends of the support shaft 21 inserted into the center of the
As shown in FIG. 2, by engaging the engaging claws 10 and 10' located at the lower positions from above and driving the motor 11 in the forward rotation direction, the roll-shaped original fabric 20 is rotated into the third position. As shown in the figure, the chains 9, 9' rise to the top dead center position.

On the other hand, on the second inclined surfaces 7b and 7'b of the upper surface of each of the side frames 7 and 7', there are fitted members 23 having a cross-sectional shape along the second inclined surfaces 7b and 7'b, respectively. ，
23' are fixed with fasteners such as bolts and nuts, and the upper surfaces of these fitting members 23, 23' are used as guide surfaces 24, 24', and both ends of the support shaft 21 of the roll-shaped raw fabric 20 are fixed. The protruding portion is caused to roll toward the spreading machine main body 1 from the top dead center position (the position shown in FIG. 3) of the chains 9, 9'. Furthermore, chain 9,
9', the protrusions at both ends of the support shaft 21 of the roll-shaped original fabric 20 lifted to the top dead center position are connected to the guide surface 2.
4, 24, both ends of the rotating shafts 8a, 8'a of the sprockets 8, 8' are provided with
Feed rollers 25, 25, 26 having a diameter slightly higher than the top dead center position of the chains 9, 9';
26 are fixed respectively.

Further, at the terminal ends of the fitted members 23, 23,
A releasable roller 27 is disposed horizontally between the left and right side frames 7, 7'. This unraveling roller 27
has an elastic member 27a made of hard rubber or the like on the outer periphery, and the roll-shaped original fabric 20 that has rolled from the guide surfaces 24, 24 of the fitting members 23, 23
The elastic member 27a absorbs the impact and also provides impact. In addition, this unraveling roller 2

4 and 24' toward the spreading machine main body 1 side.
As shown in FIG.
It is stopped by the elastic member 27a on the outer periphery of the unraveling roller 27, and is set at this original fabric supply position.

Then, when the unrolling roller 27 is rotated in the direction of arrow C with respect to the set rolled raw fabric 20, the edge 20a of the rolled raw fabric 20 is automatically fed out to the side of the main body 1 of the rolling machine. Therefore, it can be easily set in the main body 1 of the spreading machine.

In addition, when feeding the next roll-shaped original fabric, the motor 11 is driven in the reverse rotation direction, and the engaging claws 10, 10' are brought to the lower position, and in this state, the same operation as described above is performed again. That's fine.

(Effects of the invention) As described above, according to the invention, the original fabric supply device is integrally provided at the rear of the main body of the spreading machine so that it can move together with the main body of the spreading machine. There is no need to provide the supplying device with a stand for stably placing it on the spreading table, and the original fabric supplying device can be significantly downsized. Therefore, there is no need to make the spreading table very long in order to place the original fabric supply device on the spreading table as in the past, which eliminates the problem of space and the extra cost required for the spreading table. can solve the problem.

Furthermore, the present invention allows the claw to be engaged with the support shaft of the roll-shaped original fabric to be lowered close to the spread table, and the support shaft of the roll-shaped original fabric can be engaged with this low-positioned claw. After that, the rolled original fabric is automatically transported to the high-level original fabric supply position (unraveling roll) by the original fabric supply device, so that the rolled original fabric is not transferred to the original fabric supply position (unraveling roll). The setting work can be done very easily.

By the way, the height of the raw fabric supply position (unraveling roll) is usually at a high position of 120 cm or more near the human arm or higher than the arm. It is a very difficult task for two people to lift up a heavy roll of material by holding both ends of the support shaft of the roll and set it at the material supply position (unraveling roll). When adopted, the roll is attached to a claw that can be lowered close to a spreading table (usually 70 to 80 cm high) that is set lower than a person's waist (usually lowered to about 5 to 15 cm above the spreading table). Since it is only necessary to engage the support shaft of the roll-shaped raw fabric, the height at which a person can lift the roll-shaped raw fabric is around the waist of the person or slightly higher than the waist, which is higher than the human arm. There is no need to lift a heavy roll of raw material to a height, and the raw material supply position of the rolled raw material (unraveling roll)
This makes setting it up very easy.

In addition, the above-mentioned fabric supply device uses complicated chains, sprockets, and other mechanical parts in order to move the support shaft of the roll-shaped fabric transported upward to the main body of the spreading machine and set it at the fabric supply position. There is no need to provide it, and the configuration can be greatly simplified, and this simplification of the configuration can also contribute to miniaturization of the original fabric supply device.

Moreover, since the rolled material being rolled toward the main body of the spreading machine along the guide surface is made to collide with a roll having an elastic member on the outer periphery, shock absorption is reliably achieved. , it is possible to effectively prevent damage to the fabric supply device and the main body of the spreading machine, and furthermore, the rolled fabric can be prevented from impacting with its own weight acting on the unwinding roller side due to the downwardly inclined guide surface. Therefore, by rotating the unraveling roller, the rolled original fabric is also rotated synchronously, and the edge of the rolled original fabric can be reliably fed out.

In addition, according to the configuration of the present invention, since the fabric supply device is integrally provided at the rear of the fabric spreading machine body, even if the stroke of the fabric spreading machine body is changed to a stroke other than the maximum stroke, the A roll-shaped original fabric can be easily supplied to the spreading machine main body located at the turning point in the changed stroke, and there is no need to move the spreading machine main body to the turning point at the maximum stroke each time the original fabric is supplied. Therefore, there is no need for the troublesome work of resetting the turning point of the main body of the spreading machine each time the raw material is supplied, and the reduction in efficiency of the spreading work due to the supply of raw material can be avoided as much as possible. can. Moreover, once the turning point has been set, there is no need to change it unless there is a need to change the sheet spreading mode. There will be no inconvenience caused by an unexpected change in the spread pattern.
