Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a roll-shaped raw fabric (a raw fabric in which a cloth is wound around a core tube in the form of a roll: hereinafter referred to as the raw fabric).
Receiving and receiving of roll-shaped original fabric used to feed the original fabric from the original fabric loading table to the original fabric support mechanism of the spreading machine, and to discharge the rolled original fabric from the original fabric support device to the collection table. Regarding equipment.

[Conventional technology]

In the spreading work using a spreading machine, the spreading machine is moved forward on a spreading table (work table), and the end of the fabric that is fed out into a sheet from the original fabric placed on the fabric support mechanism of the spreading machine is After fixing the fabric to the spreading table using the catcher, the fabric is fed out and spread on the spreading table while the spreading machine is moved backward. When the fabric is spread to a predetermined width, the spreading machine is stopped and the spread fabric is cut into cutters. This is done by stacking a predetermined number of fabrics on a spreading table by repeating a series of steps over and over again, including cutting and separating them from the fabric spreading machine.

In such a fabric spreading operation, the work of loading the fabric onto the fabric support mechanism of the fabric spreading machine and the work of recovering the spread fabric from the fabric support mechanism have conventionally been performed manually.

[Problem that the invention seeks to solve]

However, manual loading and retrieval work not only requires a lot of manpower, but also has the problem of harsh working conditions and poor work efficiency. In other words, spreading is not limited to stacking up many pieces of fabric drawn from the same raw fabric, but there are also cases where fabrics drawn from different fabrics are stacked in a predetermined order. It is necessary to load and retrieve heavy raw material many times in order to perform wrapping, which greatly increases the burden on the workers.
Furthermore, when recovering the original fabric, it is necessary to wind up the fabric that has been unwound from the original fabric.
It takes a lot of time and effort to wind it up, which reduces the efficiency of the spreading process.

This invention solves the above-mentioned problems, and has a roll-wound shape that allows the loading of the original fabric into the original fabric support mechanism of the spreading machine and the recovery of the original fabric from the original fabric support mechanism without relying on human power. By providing a device for receiving and delivering original fabrics, it is possible to completely automate the spreading process using not only the same original fabric, but also different original fabrics, and the purpose is to improve the spreading efficiency. .

[Means for solving problems]

The measures taken to achieve the above objectives are:
An elevating unit that is attached to a pedestal so that it can be raised and lowered is equipped with two fabric holders that hold roll-shaped fabrics in upper and lower levels, and the upper tier of fabric cradle is placed in a fabric receiving position. and a mechanism that swings the lower fabric cradle between the fabric receiving posture and the fabric discharging posture, and a mechanism that swings the lower fabric cradle between the fabric receiving posture and the fabric discharging posture, and the lifting unit moves from the lower limit position to the fabric discharging position. When it rises to the upper limit position, the upper fabric holder moves upward from the fabric receiving position corresponding to the fabric mounting table to the fabric delivery position corresponding to the fabric support mechanism of the spreading machine, and the lower fabric While the cradle moves upward from the fabric discharge position corresponding to the collection table to the fabric payout position of the fabric support mechanism, when the lifting unit descends from the upper limit position to the lower limit position, the upper fabric cradle moves The upper and lower sheet holders are moved up and down so that the lower sheet holder moves downward from the delivery position to the sheet receiving position, and the lower sheet holder moves down from the sheet unloading position to the sheet discharge position. The mutual spacing in the direction is set, and the lower raw fabric holder is made up of a plurality of rolls arranged in parallel that can rotate in the same direction.

[Effect]

The receiving and delivering device having the above configuration operates as follows.

When the lifting unit rises from the lower limit position to the upper limit position, the upper fabric cradle moves upward from the fabric receiving position to the fabric delivery position, and at the same time, the lower fabric cradle moves from the fabric discharge position to the fabric payout position. move up to Conversely, when the lifting unit descends from the upper limit position to the lower limit position, the upper fabric holder moves down from the fabric delivery position to the fabric receiving position, and the lower fabric cradle moves the fabric from the fabric delivery position to the fabric receiving position. Moves down to the ejection position. When the lifting unit is lowered to the lower limit position, the original fabric is fed from the original fabric loading table to the upper original fabric holder, and the original fabric is discharged from the lower original fabric holder to the original fabric recovery table. When the lifting unit is raised to the upper limit position, the original fabric is transferred from the upper fabric holder to the fabric support mechanism, and the fabric is transferred from the fabric support mechanism to the lower fabric support mechanism. The raw material is dispensed to a holder. Further, when the raw fabric is paid out to the lower raw fabric holder, the plurality of rolls rotate in the same direction, and the sheet-like fabric being unwound from the original fabric is wound up onto the original fabric.

〔Example〕

FIG. 1 is a schematic perspective view showing the main parts of the receiving and delivering device according to the embodiment. The above-mentioned apparatus is equipped with an elevating unit 1 which is attached to a stand (not shown) via a guide member so as to be movable up and down. The lifting unit 1 includes two fabric holders 2 and 3, and these fabric holders 2,
3 is equipped with left and right mounting plates 4, 4 attached at a predetermined interval in two stages, upper and lower,
A mechanism (hereinafter referred to as a swinging mechanism) for swinging each of the fabric holders 2 and 3 is provided between the mounting plates 4 and 4 and the fabric holders 2 and 3. The upper fabric holder 2 is formed by fixing plates 6, 6 to both ends of a gutter-shaped fabric receiving member 5. In addition, the swinging mechanism on the upper sheet holder 2 side illustrated in FIG. 8 is fitted into an arcuate guide hole 9 formed in the mounting plate 4, and the plate body 6 is made to follow the eccentric cam 10. 11 is a motor for driving the eccentric cam, and 12 is a power transmission means consisting of a chain, sprocket, etc. The lower raw fabric holder 3 has two parallel rolls 14, 15 provided between the left and right plates 13, 13, and two rods placed on both sides sandwiching these rolls 14, 15. It consists of 16 and 17. In addition, the swinging mechanism of the lower workpiece holder 3 illustrated in FIG. pin 1

Both ends of the drive motor 23a are connected to the mounting plates 4, 4, and the rotating shaft of the drive motor 23a is connected to one of the sprockets.

Next, the effect will be explained.

When the drive motor 23a is rotated, the elevating unit 1 is raised, and when the drive motor 23 is rotated in the opposite direction, the elevating and lowering unit 1 is lowered. Arrow A in Figure 3
As shown in , when the lifting unit 1 descends and the end of the mounting plate 13 of the lower original fabric holder 3 hits the protrusion 22, the end of the plate 13 that is in contact with the protrusion 22 is prevented from descending. Therefore, as the elevating unit 1 further descends, the material holder 3 tilts counterclockwise in the figure about the shaft 18. Further, when the lifting unit 1 rises from the tilted state of the fabric cradle 3, the fabric cradle 3 gradually rotates around the shaft 18 to its original position due to its own weight, and the fabric cradle 3 returns to its original position. After the original fabric holder 3 is completely restored, the protrusion 2

The plate body 6 follows the eccentric cam 10 and tilts around the shaft 7 from the position indicated by the solid line in the figure to the position indicated by the imaginary line. When the eccentric cam 10 rotates once, the plate 6 tilts to the position indicated by the imaginary line, and then returns to the position indicated by the solid line in the figure.

FIG. 6 shows the above-mentioned receiving and delivering device installed between the fabric spreading section and the raw fabric supply and recovery section. The fabric spreading section is provided with a fabric spreading table 30 and a fabric spreading machine 31, and the fabric spreading machine 31 includes a fabric support mechanism 33 provided on a fabric spreading machine main body 32. Spreading is carried out according to the following steps. That is, the spreading machine 31 is moved forward with respect to the catcher 34 installed on the spreading table 30, and the roll-shaped original fabric supported by the original fabric support mechanism 33 is fed out in the form of a sheet from the spreading machine main body 32. The leading end of the fed-out fabric is fixed on the spreading table 30 by the catcher 34, and then, while feeding out the fabric, the spreading machine 31 is moved backward to spread the fabric on the spreading table 30. When the cloth is expanded by a predetermined width, the retreat of the cloth spreading machine 31 is stopped, and the cloth is cut off by a cutter device provided in the cloth spreading machine main body 32. Next, the fabric spreading machine 31 is moved forward again, and the new end of the fabric is fixed on the fabric spreading table 30 by the catcher 34, and then the fabric spreading machine 31 is moved backward while feeding out the fabric, so that the fabric has already been spread. Stack a new piece of cloth on top of the cloth and separate it. By repeating this cycle many times, a predetermined number of pieces of fabric cut to a predetermined width are piled up.

In the original fabric supply and recovery section, an original fabric mounting table 35 and an original fabric recovery table 36 are arranged in two stages, upper and lower. The original fabric mounting table 35 is inclined so that the part closer to the receiving and delivering device is located at a lower position, while the original fabric collecting table 36 is inclined so that the part closer to the receiving and delivering device is located at a lower position. A rotating shaft 37 having rotating blades 38 is provided at the bottom of the original fabric mounting table 35, and as shown in FIG. It is structured like this. Here, the rotating blades 38 are provided at a plurality of locations in the axial direction of the rotating shaft 37.
40 is a drive motor connected to the rotating shaft 37 via a power transmission means 41 such as a chain or a sprocket. Further, a plate body 43 having a rising portion 42 is fixed to the original fabric mounting table 35 with screws 44 . This plate body 43 can be moved in the front-rear direction with the screws 44 loosened.

Feeding of the original fabric from the original fabric mounting table 35 to the original fabric support mechanism 33 of the spreading machine 31 and discharge of the original fabric from the original fabric support mechanism 33 to the original fabric recovery table 36 are performed via the above-mentioned receiving and delivery device. However, the original fabric support mechanism 33 is designed to ensure that the original fabric is fed to the original fabric support mechanism 33 and the original fabric is discharged from the original fabric support mechanism 33 reliably and smoothly. That is, the fifth
As shown in the figure, the original fabric support mechanism 33 is equipped with a pair of front and rear support stands 45, 46, of which the rear support stand 46 can be raised and lowered around a shaft 47, and its tip end is A fabric dispensing posture in which the tip is located below the axis 47 (indicated by a phantom line A in the same figure), and a fabric receiving posture in which the tip is slightly above the axis 47 (indicated by a phantom line B in the figure). Alternatively, it is possible to maintain either of the original fabric holding positions (indicated by a solid line in the figure) in cooperation with the front support stand 45 to form a V-shape. 48 is a support stand 46
A motor 49 is a power transmission means for transmitting the rotation of the motor 48 to the shaft 47.

Here, the mutual distance between the upper workpiece holder 2 and the lower workpiece holder 3 of the lifting unit 1 is such that when the lifting unit 1 rises from the lower limit position to the upper limit position, the upper workpiece holder 2 It moves upward from the original fabric receiving position corresponding to the original fabric mounting table 35 to the original fabric delivery position corresponding to the original fabric support mechanism 33 of the spreading machine 31, and the lower original fabric receiving table 3 corresponds to the original fabric recovery table 36. When the elevating unit 1 is lowered from the upper limit position to the lower limit position, the upper fabric holder 2 moves upward from the fabric delivery position to the fabric delivery position of the fabric support mechanism 33. It is set so that it moves downward to the reverse receiving position, and the lower fabric receiver 3 moves downward from the fabric payout position to the fabric discharge position.

By controlling the rotating blades 38, receiving and delivering device, and fabric support mechanism 33 as described above to operate in a predetermined order, it is possible to spread not only the same fabric using the same fabric but also the fabric spreading using different types of fabric. automation is easily achieved. Next, an example of automating the spreading process using three types of raw fabrics will be described.

As shown in FIG. 6, one of the three types of roll-shaped raw fabrics 53 has already finished spreading and is still held by the fabric support mechanism 53, while the other two types are It is assumed that the original fabrics 50 and 51 are placed in order on the original fabric mounting table 35. By pressing the start button on the operation panel 52, a spreading start signal is input to the drive motor 40 and the rotary blade 38 is rotated, and the rotary blade 38 rotates 90 degrees as shown in FIGS. 4 and 7. The limit switch LS ₁ is kicked, the drive motor 40 is stopped, and the rotation of the rotating blade 38 is stopped. Further, as the rotary blade 38 rotates, the original fabric 50 placed on the original fabric mounting table 35 climbs over the rising portion 42 of the plate body 43 shown in FIG. 4 and descends to the lower limit position as shown in FIG. 7. The raw material is received on the upper shelf 2 of the lifting unit 1. At this time, as shown in the figure, the original fabric receiving stand 2 is in an untilted position at the original fabric receiving position corresponding to the original fabric mounting table 35;
In other words, the original fabric receiving posture is maintained. When the original fabric 50 is received on the original fabric holder 2, a timer (not shown) is activated.
After a predetermined period of time, the drive motor 23a shown in FIG.
When the lifting unit 1 rises to the upper limit position _shown in FIG. At the same time as it stops at the position, the limit switch
The output signal of LS ₂ is also input to the motor 48 shown in FIG. 5, the support base 46 of the web support mechanism 33 is pivoted downward, the limit switch LS ₆ shown in the same figure is kicked, and the motor 48 is stopped. The support stand 46 also stops, and the original fabric support mechanism 33 is held in the original fabric delivery position. When this happens, the original fabric 53 that has been held by the original fabric support mechanism 33 is discharged as shown by arrow B in FIG. 8 and received by the lower original fabric holder 3.
While the original fabric 53 is being dispensed from the original fabric support mechanism 33, the proximity switch SW detects that the original fabric 53 is being dispensed. The detection signal of the proximity switch SW is input to the motor for rotating the rolls 14 and 15 of the original fabric holder 3, and these rolls 1
4 and 15 rotate in the same direction shown by arrows X and Y in FIG. For this reason, the raw fabric 53 is
It rotates while riding on the cloth 5, and the sheet-like cloth that has been fed out by spreading is wound up onto the raw cloth 53. When this winding is completed, a signal detecting this starts the motor 48, and the support base 46 starts to rotate upward. When the support stand 46 is turned upward and the limit switch LS ₃ is kicked, the motor 48 is stopped and the original fabric support mechanism 33 is set to the original fabric receiving posture. After the original fabric support mechanism 33 is in the original fabric receiving position, the limit switch is turned on.
The motor 11 shown in FIG. 2 is started by the LS ₃ output signal, and the eccentric cam 10 rotates by a predetermined angle. The eccentric cam 10 tilts the upper sheet holder 2 as shown in FIG. It is in the ejecting position and 50 sheets of raw material are
is transferred to the original fabric support mechanism 33 as shown by arrow C.
The rotation angle of the eccentric cam 10 is controlled by a limit switch _LS7 (see FIG. 2). When the original fabric 50 is transferred to the original fabric support mechanism 33 in this way, this is detected by an appropriate means such as a proximity switch (not shown), and the detection signal is used to drive the motor 4.
8 is started, the support stand 46 of the original fabric support mechanism 33 is pivoted upward, and the original fabric support mechanism 33 is maintained in the original fabric holding posture shown by the solid line in FIG. Note that the motor 48 is stopped when the limit switch LS ₄ is kicked by the support base. After this, the sheet is fed out from the original fabric 50 and the spreading machine 31 is moved forward and backward, and the above-described spreading is performed.In this embodiment, the original fabric support mechanism 33 is in the original fabric holding position Frame 2 of the device for receiving and delivering gifts
This is detected by the limit switch LS ₅ installed at 1, and spreading is started after that, increasing the stability and reliability of the work.

While the fabric spreading machine 31 is spreading the fabric, the fabric 53 received by the fabric receiving table 3 in the lower stage is discharged to the fabric recovery table 36. That is, when the lifting unit 1 is lowered to a predetermined height by the operation of the drive mechanism 23, the plate 13 is lowered as explained in FIG.
The end of the sheet hits the protrusion 22 to prevent its descent, and as the elevating unit 1 further descends, the web holder 3 tilts counterclockwise in the figure around the shaft 18, and the web The ejection position is set. Therefore, the original fabric 53 is discharged from the original fabric receiving table 3 to the original fabric recovery table 36 as shown by arrow D in FIG.

The original fabric 51 is spread after the original fabric 50 is recovered after being spread. By doing the above, the original fabric 53,5
1 and 52 can be spread in this order.

In the above explanation, three types of raw fabrics 53, 50, 5
Although the description has been given of the case where the first fabric is spread in order, the same applies to the case where two or four or more types of raw fabrics are spread. Further, the operation control of the rotary vane 38, the receiving and delivering device, and the spreading machine 31 is not limited to the one described above, but may be performed using other control methods.

〔Effect of the invention〕

As explained above, according to the present invention, the work of feeding the original fabric from the original fabric mounting table to the original fabric support mechanism of the fabric spreading machine, and the operation of transporting the spread original fabric from the original fabric support mechanism to the original fabric recovery table. When the paper is collected in a machine, the work and the work of winding up the sheet-like fabric that has been unwound from the original fabric onto the original fabric can be performed automatically in a fixed order, which greatly reduces the amount of manpower required for rolling the fabric compared to the past. It is possible to improve the efficiency of the spreading work. Such an effect is particularly noticeable when the fabric is spread, such that fabrics unrolled from different raw fabrics are piled up in a predetermined order.
