Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus that can efficiently perform an operation of cutting an original fabric and laminating the cut fabric on a required position on a fabric stacking table.
[0002]
[Prior art]
Clothes for clothes and Japanese clothes are supplied as very long rolls of raw material. After cutting the raw material into a predetermined length, it is further cut into various types of parts and processed into desired parts through a sewing process. It is marketed as. For example, in the case of suit clothing, the fabric worn by suit 1 is less than 2 meters long and reaches about 1 meter wide. Various improvements have been proposed for automatically or semi-automating the process of laminating fabrics cut from a roll-shaped raw fabric because the fabric of this size is light in weight but large in area and difficult to handle.
[0003]
For example, the raw fabric is cut by a conventional fabric laminating apparatus and the cut fabric is laminated on the fabric laminate in the manner shown in FIGS.
As shown in FIG. 8A, the base end portion b of the fabric holding belt a is fixed to an original fabric holding portion (not shown), and the distal end side of the fabric holding belt a is wound around a belt winding roller c. Both ends of the take-up roller c are supported by a pair of carriages (not shown).
The fabric e at the tip of the web d wound on the roll is guided onto the fabric guide plate f that moves together with the belt take-up roller c, and is held on the fabric guide plate f by the fabric presser g. The symbol h is a fabric laminate.
[0004]
As shown in FIG. 8B, when the belt take-up roller c moves from the state to the right in the figure, the fabric holding belt a taken up by the belt take-up roller c is gradually unwound and the belt take-up roller c is unwound. The fabric e is supplied from the original fabric d onto the roller c.
When the leading end of the fabric e reaches a predetermined position, the fabric presser g is released, and the belt take-up roller c is moved to the left in the drawing as shown in FIG. 8C. Thereby, the front end side of the fabric e moves to the fabric laminate h. As shown in FIG. 8D, when the belt take-up roller c reaches a predetermined position (position in FIG. 8A), the fabric e is separated from the original fabric d by the fabric cutter j and laminated on the fabric laminate h.
[0005]
By repeating the steps of FIGS. 8A to 8D, a plurality of fabrics e are stacked in a aligned state on the fabric laminate h.
However, comparing the states of FIG. 8A and FIG. 8B, the distance between the base end b and the belt take-up roller c is short in FIG. 8A and the fabric holding belt a is not easily loosened, whereas in FIG. The distance between the portion b and the belt take-up roller c is long, the fabric holding belt a is slackened, and the position of the belt take-up roller c and the position of the dough laminate h are not accurately matched. Lamination may not be possible.
In order to eliminate this drawback, it has been proposed to eliminate the slack of the belt using the force of the motor.

[0007]
[Problems to be solved by the invention]
For example, in Patent Document 1, a sheet (fabric holding belt) is pulled out or pulled back from a take-up roller by rotation of a motor, and a slight force is applied to the motor so that the cloth holding belt does not loosen. Is disclosed.
In the fabric laminating apparatus described in Patent Document 1, the base end portion of the sheet 17 corresponding to the fabric holding belt a in FIG. If the belt winding roller c in FIG. 8 is continuously applied with a motor by a motor, a load opposite to the traveling direction is applied to the carriage for moving the belt winding roller c, and smooth traveling is hindered. There is a drawback that the balance deteriorates.
Accordingly, an object of the present invention is to provide a fabric laminating apparatus that can apply a balanced force to the carriage regardless of the fabric holding belt at any stage of fabric lamination, and can perform fabric cutting and lamination in a balanced and highly accurate manner. To do.
[0008]
[Means for Solving the Problems]
Accordingly, the present invention provides a fabric stacking table, a fabric holding belt whose base end is fixed, moving the space on the fabric stacking table and transferring the fabric, a belt take-up roller wound around the distal end side of the fabric holding belt, A cloth laminating apparatus comprising a carriage that travels while supporting the belt take-up roller at both ends, a timing belt that supports the carriage, and a cutting cutter for cutting the cloth, and is installed in parallel with the belt take-up roller. The dough laminating apparatus further includes a spring shaft that applies to the belt take-up roller a reverse rotational force that is balanced with a rotational force applied to the belt winding roller.
[0009]
The present invention will be described in detail below.
In the present invention, a cloth laminating device that applies an appropriate force to the carriage substantially regardless of the position of the belt take-up roller, imparts an appropriate tension to the cloth holding belt, and allows the carriage to run smoothly. I will provide a.
The dough laminating apparatus as an object of the present invention is configured to run a belt take-up roller wound around the other end of a dough holding belt having one end fixed as shown in FIG. A device for stacking.
[0010]
When the belt take-up roller conveys the fabric, etc., the fabric holding belt tends to become loose as the belt take-up roller travels in the forward direction (the direction in which the original fabric is supplied from the original fabric roll). In this case, if the belt take-up roller is given a rotational force that gives tension to the dough holding belt, the dough holding belt is given appropriate tension without causing slack regardless of the position of the belt take-up roller. be able to. However, the rotational force applied to the belt take-up roller is also transmitted to the carriage, which adversely affects the running balance of the carriage.
Therefore, if the rotational force applied in the opposite direction to the rotational force applied to the belt take-up roller is applied to the carriage, both rotational forces are balanced and the carriage can run in a balanced manner without causing the fabric holding belt to become slack. It becomes possible.
Thereby, the precision of operation in each process of conveyance (cutting) of original fabric (fabric), cutting, and lamination improves, and the cutting of the target cloth and the lamination of the cutting cloth on the stacking table can be performed with high accuracy.
[0011]
Specifically, it is desirable to apply an appropriate tension force that balances the dough holding belt using a repulsive force of a spring, for example, a tension having a spring close to or coaxially with the belt winding roller. A spring shaft is installed so that the tension spring shaft and the belt take-up roller are interlocked. At this time, if the force applied to the carriage is balanced by applying a force in the opposite direction to the force applied to the carriage via the belt take-up roller, the carriage is in a state in which no load is generated. Carriage can be run simply by applying force.
In particular, it is desirable that this operation can be performed without any special additional operation in conjunction with the travel of the carriage.
[0012]

An original fabric holding bar 11 is erected on both ends of the original web holding table 10, and cutting and laminating are performed from an original roll 13 supported by a rod 12 spanned between the two original web holding bars 11. The fabric 14 to be extended extends toward the space above the fabric laminate 6.
[0014]
A carriage drive pulley 15 is horizontally installed on the inner surface of the main body 9, and this pulley 15 is connected to a carriage drive motor 17 by an endless belt 16. A tension pulley 18 is horizontally installed slightly below the right end of the guide rail 7 in FIG. 2, and a carriage drive belt 19 is bridged between the tension pulley 18 and the carriage drive pulley 15.
When the carriage drive motor 17 is turned on, the rotation of the motor 17 is transmitted to the carriage drive pulley 15 by the endless belt 16, and the carriage drive belt 19 between the pulley 15 and the tension pulley 18 travels to move the carriage 8. It runs along the guide rail 7.
[0015]
On the inner surface of the side wall of the main body 9, a fabric holding belt fixing tool 20 is installed, and a base end portion of a sheet-like material holding belt 21 is fixed to the fixing device 20. As shown in FIG. 3, the other end of the fabric holding belt 21 is wound around a belt take-up roller 22 installed between the left and right bent portions of the carriage 8, and the roller 22 is moved by the movement of the carriage 8. The tip of the fabric holding belt 21 (the tip of the unwound portion) travels by the amount of the rotation.
One end side of the belt take-up roller 22 is configured as an annular gear 23, and an endless chain gear 24 is engaged with the annular gear 23.
[0016]
A tension spring shaft 25 (which may be replaced with a mainspring) is installed slightly above the belt winding roller 22 so as to be bridged between the two carriage bent portions. The tension spring shaft 25 is connected so that one end can be rotated by a driven gear 26 and the other end can be rotated by a bearing 27 to both bent portions of the carriage. At the end of the tension spring shaft 25 on the bearing 27 side, a spring shaft-side annular gear 28 that is fitted to the shaft 25 and rotates separately is formed, and the chain gear 24 that travels between the annular gear 28 and the annular gear 23 is formed.

The laminated body 35A to be moved can be moved through the space (see FIG. 2) and collected in one place, and the efficiency when using a plurality of devices at the same time can be improved.
[0019]
In the example of FIGS. 8A to D, when a rotational force is applied to the belt take-up roller c with a motor, the carriage is also subjected to force, and the carriage travel balance is easily lost. Such smooth running cannot be obtained. However, according to this embodiment, the belt winding roller 22 and the tension spring shaft 25 are applied with balanced rotational forces in opposite directions, so that the slack of the dough holding belt 21 can be removed without substantially applying a load to the carriage. It can run smoothly and the cut fabric can be laminated with high accuracy.
[0020]
Next, a mechanism for applying a balanced rotational force in the opposite direction to the belt take-up roller 22 and the tension spring shaft 25 in the apparatus of this embodiment will be described with reference to FIGS.
[0021]
FIG. 5 is a perspective view showing a state in which the spring 30 is wound around one tension spring shaft 25.
In FIG. 5, the spring 30 wound around the tension spring shaft 25 has an end I and an end II, and when a force is applied to the end I and the end II as indicated by arrows, Repulsive forces in opposite directions are generated, and these repulsive forces are equal in opposite directions.
In this embodiment, the carriage is balanced using the pair of repulsive forces. The procedure will be described based on the model of FIG.
[0022]
In FIG. 6, two divided virtual shafts 25A and 25B are fitted around the tension spring shaft 25 '. The virtual shaft 25A is fixed to the tension spring shaft 25' and does not rotate with each other. The tension spring shaft 25 'can be rotated.
A strongly wound (preloaded) spring 30A is installed between the virtual axes 25A and 25B. The spring 30A is fixed to the tension spring shaft 25 'on the virtual shaft 25A side, and is rotatable on the tension spring shaft 25' on the virtual shaft 25B side. The spring 30A is strongly wound and is the same as that described with reference to FIG. 5, in which the virtual shafts 25A and 25B are fixed and lightly wound on the wires 38A and 38B in FIG. An effect is produced. As a repulsive force, a repulsive force in the direction opposite to the arrow is generated on the imaginary shafts 25A and 25B, so that a rotational force in the direction B is applied to the virtual shaft 25A, and a reverse rotational force is applied to the imaginary shaft 25B. Both rotational forces are in the opposite direction, but the same force.
[0023]
The rotational force shown in FIG. 6 is also generated in the apparatus of FIG.
That is, in FIG. 3, the spring 30 having one end fixed to the spring fixing collar 29 and the other end fixed to the annular gear 28 and being rotatable with respect to the tension spring shaft 25 in FIG. A rotational force for rotating the tension spring shaft 25 is applied in the direction indicated by (2), and this rotational force is transmitted from the driven gear 26 to the carriage 8. Therefore, the leftward force shown in FIG. 4 is applied to the fixed timing belt 34 or the carriage 8 connected to the driven gear 26.
The spring 30 applies a rotational force in the direction B in FIG. 5 to the annular gear 28, and this rotational force is transmitted to the belt take-up roller 22 through the chain gear 24, and the belt take-up roller 22 causes the dough holding belt 21 to move. As shown in FIG. 3, the belt winding roller 22 gives a rotational force that rotates clockwise. Further, this rotational force is transmitted to the carriage 8 connected to the belt take-up roller 22, and the rightward force shown in FIG. 4 is applied.
[0024]
In the fabric laminating apparatus configured as shown in FIG. 3, a balanced force is applied to the carriage 8 in this manner, and the balance of the carriage 8 is maintained.
As described with reference to FIGS. 1 and 2, the carriage 8 travels along the guide rail 7 by the power of the carriage drive motor 17, but this balance is maintained during traveling, in other words, the carriage 8 is located at any position. But the above-mentioned equilibrium holds. Therefore, no extra force is applied to the carriage 8 and the vehicle can run smoothly only with the power from the carriage drive motor 17. Thereby, it is possible to perform the cutting of the cloth from the original fabric, the transfer of the cut cloth, and the lamination, which are the original functions of the cloth laminating apparatus, with high accuracy.
[0025]
FIG. 7 shows another embodiment, which is an example in which the tension spring shaft and the belt take-up roller in the above-described embodiment are coaxially reduced in size.
A belt take-up roller 22A is installed around the tension spring shaft 25C so as to be coaxial with the shaft 25C, and a spring 30B is accommodated between the tension spring shaft 25C and the belt take-up roller 22A. One end of the spring 30B is fixed to the spring fixing collar 29A of the tension spring shaft 25C, and the other end is fixed to the inner surface of the belt winding roller 22A and is movable according to the rotation of the belt winding roller 22A.
[0026]
One end of the tension spring shaft 25C is connected to one bent portion of the carriage 8A via a bearing 36 and a bearing 27A, and the other end of the tension spring shaft 25C is connected to the other bent portion and also connected to the rack gear 37. is doing. A fabric holding belt 21A is wound around the belt winding roller 22A.
Also in this embodiment, a pair of repulsive forces in the opposite directions generated by the spring 30B on the tension spring shaft 25C are transmitted to the carriage 8A to balance the carriage 8A.
[0027]
