BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing machine.

[0002]

2. Description of the Related Art A reversing machine is widely used as a means for stacking a large number of fabrics in layers and cutting them into a fixed mold size. This reversing machine is provided with a means for supporting the web at the upper part, a releasing means such as a roll at the front end, and a cutter means movable at a lower part of the front end in a direction orthogonal to the direction of the elongation. The dough is stacked on the roll base by the reciprocating motion on the counter base, the driving of the release means, and the cutter means. As a method of supporting the raw material, there is a type in which the central axis is inserted into the raw material, and this central axis is supported by a gantry to support the raw material on the hollow. There are problems such as the necessity of complicated work for removing and collecting the center shaft after mounting and spreading, and that the peripheral speed of the raw material is not constant. Therefore,
There is a method in which a raw material is directly placed on a plurality of parallel support rolls. At the time of rolling by this method, the raw web is intermittently rotated by the rotation of the support roll according to the degree of breaking, but it is impossible to completely synchronize the breaking speed by the breaking means and the drawing speed of the raw fabric. It is difficult, and the raw material is not necessarily perfectly round, and is not always wound uniformly. Further, the fabric is easily sent out extra due to the inertia of the support roll. For these reasons, during the spreading operation, the amount of the dough increases suddenly and irregularly between the supporting means and the releasing means, and a phenomenon occurs in which the dough becomes crumpled, thereby the dough spread on the spreading table. Wrinkles are likely to occur. If the wrinkles are present, a shift occurs in the layered dough, and appropriate pattern cutting cannot be performed due to a shift in a design or pattern.

[0003] As a countermeasure for this, conventionally, the cloth is provided with a slack in a path between the material releasing means and the material supporting means. However, in order to allow the cloth to have a sufficient slack. However, since a deep groove-shaped space must be formed in the reversing machine, there are problems that the reversing machine becomes large and it is difficult to control the amount of slack properly. In general, as a method of preventing wrinkles at the time of spreading, a plate is provided in the cloth path between the raw material supporting means and the breaking means as disclosed in JP-A-59-48354 and JP-A-62-230555, This is vibrated by a vibrating device including a vibration oscillator to give vibration to the dough. Also, as disclosed in Japanese Utility Model Laid-Open Nos. 54-30253 and 63-178254, There has been proposed a method in which a roller having a spiral ridge of a reverse screw type is mounted from the center, and the dislodged cloth is pressed against the spiral ridge by driving the roller with a motor. However, these prior arts require a complicated mechanism for the wrinkle removing device, which is expensive, and the entire reversing machine is large and heavy, so that the burden on the drive mechanism for reciprocating the reversing machine increases. there were.

Japanese Patent Application Laid-Open No. 60-44468 discloses a distribution pipe in which a nozzle is disposed in front of a reversing machine, and the distribution pipe is connected to an external compressor with a hose. A method has been proposed in which compressed air is blown onto the dough that falls on the base. However, this prior art requires an expensive air compressor and additional facilities such as installing a hanger rail above the rolling base to synchronize the hose from the air conditioner puller with the reciprocating motion of the spreading machine. I do. For this reason, there is also a problem that it is expensive and large.

The present invention has been devised in order to solve the above-mentioned problems. The first object of the present invention is to provide a wrinkle generated due to a speed difference between a release mechanism and an original support mechanism. To
An object of the present invention is to provide a reversing machine that can be realized with a simple and inexpensive structure and without increasing the size of the reversing machine. A second object of the present invention is to provide, in addition to the above-mentioned object, a reversing machine capable of automatically setting a dough at the start of spreading by a simple structure.

[0006]

In order to achieve the first object, the present invention provides a material supporting mechanism for supporting a material and intermittently rotating the material, and a material-releasing roll for feeding the material from the material to a rolling base. In the reversing machine provided with, a dough guide having an elevation angle from below the raw fabric support mechanism toward the unwinding roll is provided, and the blowing direction is set to be non-perpendicular to the dough guide above the dough guide. A plurality of blowers are arranged in the width direction of the spreading machine, and the dough derived from the raw fabric is pressed against the dough guide by air pressure and swells backward in a loop. The control of the air pressure by the blower may be performed by controlling the number of rotations, but is more simply performed by controlling the selection of the operating number of a plurality of blowers. The dough guide has an outer dough guide extending from the lower end to the side opposite to the unrolling roll and to the back of the web support mechanism. The material support mechanism is preferably two or more rolls in parallel, and the driving of the rolls is started and stopped by a fabric stock sensor provided on the back side of the fabric guide. In order to achieve the second object, the present invention provides a belt conveyor which moves in the elevation direction instead of the cloth guide including the outer surface cloth guide.

[0007]

[Function] The original fabric is supported by the original fabric support mechanism, the end of the cloth is hung on the front side of the spreading machine via the separating roll, and the main body of the spreading machine is driven while driving the separating roll. The dough is pulled out and spread on the spreading table. If the blower is driven at this time, the air flow is sent from the blower at a moderately inclined angle instead of a right angle to the dough guide having an elevation angle, so that the dough is pressed against the dough guide with an appropriate pressure. The fabric is thereby tensioned and wrinkles are removed or prevented. Further, since the air flow flows along the inclination of the dough guide, the dough that has received the air flow swells in the direction of the anti-roll roll by the wind pressure, thereby creating a tight loop-shaped dough stock. With this dough stock, the edge of the unrolling roll side and the side of the raw sheet supporting mechanism are cut off. For this reason,
Even if the rolls of the material support mechanism are driven intermittently and the cloth is pulled out irregularly or temporarily in large quantities, the released state is kept normal and wrinkles are prevented. The dough stock is not formed as a deep groove in the vertical direction of the reversing machine, but is formed toward the rear of the reversing machine, so that the depth of the reversing machine can be reduced and the mechanism is simple.

In the case where the cloth guide is constituted by a belt conveyor, the cloth taken out of the raw material is transferred to the release roll by driving the material guide. The setting (work of hanging the dough from the raw cloth through the rolls to the front of the spreading machine) can be performed automatically without manually using a rod. The stationary belt conveyor functions as a cloth guide and wind pressure backup unit, and functions as an effective wrinkle prevention unit in cooperation with the blower.

[0016]

In the second embodiment, when it is desired to set the inner table, the raw material A is placed on the support rolls 4a, 4a, and the drive motor 9a is operated in this state, and the second clutch 91 is set. And the third clutch 92 is turned on. In this case, FIG.
, The first conductive means 9b rotates counterclockwise, whereby the support rolls 4a, 4a 'rotate counterclockwise with the second conductive means 9c. The rotation is performed by the second clutch 91
Through the first shaft 6
a rotates counterclockwise, thereby driving the conveyor belts 6d and 6e. Further, the rotation of the first shaft 6a is transmitted to the fourth conduction means 9e, and transmitted to the solution releasing roll 5 via the third clutch 92, and the solution releasing roll 5 rotates counterclockwise. By this series of operations, the raw material A rotates and the dough is fed out, and the fed out material hangs down, the tip of which comes into contact with the conveyor belt 6d, and is transferred on the conveyor belt 6d having an elevation angle in the direction of the separating roll 5. Is done. When the leading end of the dough projects to the top of the belt conveyor 6, the unrolling roll 5 rotates counterclockwise, and the dough is hung down on the front surface of the spreading machine. Then, the cloth tip sensor 21 provided on the front side of the reversing machine main body 2, for example, the photoelectric tube is turned on, whereby the drive motor 9a is stopped, and the first to third clutches 90, 91, 92 are also turned off. Thus, the driving of the conveyors 6, 6 'is stopped, and the fabric setting is automatically completed.

When it is desired to set the outer table, the driving direction of the driving motor 9a is reversed. In this example, the driving is performed clockwise, and the first clutch 90 and the third clutch 92 are turned on. In this case, the support rolls 4a, 4
a ′ is rotated clockwise by the first conduction means 9b and the second conduction means 9c, and rotates the raw material A in the opposite direction to that during the setting of the middle table. However, since the second clutch 91 is off, the rotation is not transmitted to the third transmission means 9d. That is, the rotation of the support roll 4a 'is not transmitted to the first shaft 6a. However, since the first clutch 90 is operated, the rotation of the support roller 4a is reversed by the fifth transmission means 9f, and a counterclockwise rotational force is transmitted to the third transmission means 9d via the rotating element 901 and the first shaft 6a Rotates counterclockwise and the fourth
The unrolling roll 5 rotates counterclockwise via the conducting means 9e. Therefore, the cloth of the raw material A droops from the rear side as shown by the dotted line in FIG.
It is moved on this, is continuously moved on the belt conveyor 6, and is sent to the rewinding roll 5, and is drooped to the front of the reversing machine by the rotation of the rewinding roll 5, and the cloth leading end detection sensor 21 is turned on as described above, Since the drive motor 9a is stopped and the first to third clutches 90, 91, 92 are also turned off, the fabric setting is automatically completed. Since the dough setting operation is automatically performed by the belt conveyor, labor saving and efficiency can be achieved. In addition, a complicated mechanism such that the dough is sandwiched between rolls from the front and back and slides toward the release roll is used. Therefore, the structure can be simplified.

Next, the first clutch 9
With the 0th to fourth clutches 92 turned off, the traveling motor 9j is operated to move the whole of the spreading table 1 to a predetermined start position. In the case of automatic operation, the blowers 7a to 7j are driven from this movement. As a result, the airflow is blown at a predetermined angle to the belt conveyor 6, so that the cloth portion a hanging down from the sub-support roll 4b and resting on the belt conveyor 6 at the time of middle and front spreading is shown in FIGS. As described above, the downstream portion is pressed against the belt conveyor 6, and the upstream portion swells obliquely rearward by wind pressure to form a loop-shaped stock b. At the time of outer surface spreading, when the air flow is blown at a predetermined angle to the belt conveyor 6, it flows along the cloth on the belt conveyor 6 and rises along the outer surface belt conveyor 6 '. For this reason, the outer surface fabric is appropriately pressed against the belt conveyor 6 and the outer surface belt conveyor 6 ′, and
The cloth portion a 'hanging from b' bulges rearward in response to the upward flow to form a loop-shaped stock b '.
The belt conveyor 6 and the outer surface belt conveyor 6 'are stationary at the time of extension, and function as cloth guide and backup means as in the case of the first embodiment. The blower 7
The number of drives a to 7j is to selectively operate all, every other, or every two according to the material, property, thickness, width, etc. of the material to be stretched. Can be adjusted.

At the time of extension, the driving motor 9j is driven, and at the same time, the fourth clutch 93 is turned on. As a result, the reversing machine main body 2 travels to the left in FIG. 1, and at the same time, the continuously variable transmission 9g functions to rotate the drive side gear 9i in synchronization with the traveling speed, and the driven gear 9h rotates the rewinding roll 5 Is rotated to pull out the dough, so that the spreading is started.
The drawn fabric is continuously irradiated with the air flow from the blowers 7a to 7j as described above, and the fabric is pressed against the conveyor belt 6, whereby the fabric is stretched and tensioned. As a result, the vertical and horizontal wrinkles are stretched, and the wrinkles are lifted without wrinkles. As the unraveling progresses, the loop-shaped stock b decreases, and the amount of the cloth contacting the belt conveyor 6 decreases. Then, in the case of FIG. 3, light is transmitted by the cloth stock sensors 8a and 8b, and the switch is turned on. By this switching, the drive motor 9a
Is driven, the first conductive means 9b and the second conductive means 9c rotate counterclockwise, and the support rolls 4a and 4a 'rotate.
For this reason, the raw material A is rotated in the counterclockwise direction, and the cloth is fed out. When the dough is fed, the dough stock sensor 8
a, 8b are turned off, the drive of the drive motor 9a is stopped, and the support rolls 4a, 4a 'stand still. The elongation is continued by intermittently repeating the rotation of the support rolls 4a and 4a ', and when the elongation reaches a predetermined elongation length, the cutter operates to cut the cloth. Return to start position again. At this time, the fourth clutch 93 is turned off.

The support rolls 4a, 4a are
Even if the drive of a is stopped, it rotates somewhat due to inertia. For this reason, the fabric is pulled out excessively, and as described above, the surplus fabric becomes crumpled and wrinkles are generated. In the present invention, the belt conveyor 6 is continuously fed from the blowers 7a to 7j during the spreading operation. At a moment when the dough starts to be fed out by the rotation of the support rolls 4a and 4a ', the loop-shaped stocks b and b' as shown in FIG. 3 are created by the air pressure. As well as
The dough is pressed against the belt conveyor 6. The size of the loop-shaped stocks b and b 'automatically changes according to the response delay when the drive motor 9a rises and stops, and absorbs the fluctuation of the fabric amount caused by the intermittent rotation of the support rolls 4a and 4a. . Therefore, the fabric is always kept in tension and no wrinkles are generated. The loop-shaped stock b is stable without fluctuation because one side is in contact with the belt conveyor 6,
Also, since the loop-shaped stock b is formed diagonally rearward,
It is not necessary to increase the height and length of the main unit.

In the case of FIG. 4, only the cloth stock sensor 8a operates at the time of the middle position, and when the reflected light amount is lost due to the disassembly, the cloth stock sensor 8a is turned off and a drive signal is sent to the drive motor 9a. At the time of outside, the cloth stock sensor 8b operates to perform similar detection. In the case of the first embodiment, it is necessary to set the dough manually, but at the time of rolling, the dough guide 6, the outer surface dough guide 6 ', and the blowers 7a to 7j smoothly and reliably generate no wrinkles. Protest can be performed.

[0022]

According to the first aspect of the present invention described above, a cloth guide 6 having an elevation angle from below the material support mechanism 4 toward the breaking roll 5 is provided, and the cloth guide 6 is provided above the cloth guide 6. A plurality of blowers 7a to 7j whose blowing directions are set to be non-perpendicular to the dough guide are arranged in the width direction of the reversing machine, and the dough derived from the raw fabric is pressed against the dough guide 6 by the air pressure of the blowers and looped backward. The speed difference between the continuously driven release mechanism and the intermittently driven raw support mechanism and the raw material are simple and inexpensive, and without increasing the size of the reversing machine. An excellent effect is obtained in that the generation of wrinkles due to the rotation stop accuracy of the support mechanism can be reliably prevented. Further, according to the present invention, a belt conveyor 6 having an elevation angle from below the raw fabric support mechanism 4 toward the breaking roll 5, and a lower side of the belt conveyor 6 from the lower end thereof and the back of the raw fabric supporting mechanism 4. And a plurality of blowers 7a to 7j whose blowing direction is set to be non-perpendicular to the belt conveyor 6 in the width direction of the reversing machine. Then, the dough derived from the raw material is pressed against the belt conveyor 6 by the air pressure of the blowers and swells backward in a loop, so that the above effect is obtained at the time of rolling, and before the rolling starts, The fabric setting can be automatically performed by the operation of the belt conveyors 6, 6 ', and the belt conveyors 6, 6' which are the fabric transfer means at the time of fabric setting.
In this case, a simple structure can be obtained because it functions as a cloth guide and a wind pressure backup unit at the time of rolling.
