A plurality of air holes 105 are formed in the upper position of the 103, the four sides are formed integrally with the top plate 107 is formed with the alignment groove 106 is attached.

Referring to the operating state of the present invention made of such a configuration as follows.

When power is applied, the table lifter 50 automatically rises by the thickness of the fabric placed on the upper surface.

In other words, the fabric is automatically increased by the thickness of the fabric every time the sheet is transported and is always maintained at a constant height. In the present invention, if 10 sheets of fabric are left, the taper 50 is raised to the sensing sensor 7 attached to a certain height. The beacon 8 is turned on to inform the worker of the fabric supply status.

When the table lifter 50 automatically rises, the pneumatic cylinder 11 of the adsorption means 10 is operated to lower the vacuum pad holder 12 to ground the fabric 3 as shown in FIG.

At this time, the vacuum pad 9 is a vacuum suction force is generated and at the same time as shown in Figure 6 air is injected from the air nozzle 70 to remove the dust or foreign matter on the upper surface of the fabric (3).

When air is injected from the air nozzle 70, one piece of fabric is adsorbed by the vacuum pad 90 and automatically rises by the pneumatic cylinder 11.

As shown in FIG. 7, as shown in FIG. 7, if one side is first raised to form a gap of the fabric 3, the air is injected into the gap from the air nozzle 80 attached to the upper frame 1 so that the fabric is overlapped ( Eliminates static electricity generated in 3) and prevents overlapping of fabric. After the first rise, the fabric is transferred to the upper part as a whole.

When the fabric is conveyed to the upper portion, the pinion gear 23a formed on the rotation shaft 23 is engaged with the rack 24 by the rotational power of the reduction motor 21 of the front and rear conveying means 20, and the fabric conveying table 2 is As shown in Figure 10 will be transferred to the upper position of the fabric sorter 100.

The stopper 25 formed on the left side of the drawing on the far-end transfer table 100 is conveyed at a high speed while being separated from the second limit switch 29b on the left side as it is transferred to the right side, and the first stopper 25a on the right side is formed on the right side. The grounding of the limit switch 29a is performed at low speed and the second limit switch 29c is grounded to stop the feeding to the right.

The conveyance to the left side of the far-end feed table 2 is also made by the above-described operation.

When the fabric transfer table 2 is positioned on the top of the fabric sorter 100, heat is generated from the heater in the upper portion, so that the fabric is contracted or frozen in winter so that the fabric is not squeezed to the synthetic resin during pressing. Will be.

After this process, the vacuum pad holder 12 is lowered by the pneumatic cylinder 21, and at this time, air is injected from the air nozzle 70 to remove foreign substances formed on the upper surface of the fabric during transportation and close to the fabric alignment stage 100. When the vacuum state of the vacuum pad 9 is automatically released, the fabric is placed on the upper surface of the fabric sorter 100 and the vacuum pad holder 12 is lifted and transferred to its original position.

When the fabric is placed on the fabric sorter 100, the alignment cylinder 32 is operated as shown in FIG. 16 so that the mill piece 34 pushes the fabric 3 to align.

In this case, as shown in FIG. 15, the alignment cylinder 32 is primarily operated by the A and B alignment cylinders 32 and secondly, the C and D alignment cylinders 32 are operated or vice versa.

In order to prevent the fabric from being closely adhered to the fabric sorter 100 when the fabric is aligned, air is supplied as shown in FIG. 14 to the air hole 105 through the air transport path 103. As it is injected, the fabric alignment can be made more effectively.

When the fabric is aligned, as the deceleration motor 41 of the front and rear conveying means 40 rotates, the pinion gear 43a of the rotating shaft 43 meshes with the rack 44, and the fabric feeding table 4 is shown in FIG. As shown, it is transported backward.

At this time, the stopper 45 formed in front of the dispensing stand 4 is first transported to the rear while falling away from the front second limit switch 47b, and sensing of the dispensing stand 4 by the sensing sensors 49 at both sides. If the piece 4a is matched, it will drive at a high speed toward the press side after stopping once.

During the high speed driving, the front stopper 45 changes to a low speed while grounding the rear first limit switch 47a and is grounded to the second limit switch 47c to stop the transfer. This is located.

When the fabric is placed under the upper mold, the pneumatic cylinder 101 is finally operated and the fabric sorter 100 is transferred upward to attach the fabric to the upper mold and then descend again.

When the fabric alignment stage 100 is lowered after the fabric attachment, the fabric insertion stage 4 is moved to the front, and the front stopper 45 is separated from the rear first limit switch 47a so that high-speed driving is performed forward.

If the sensing piece 4a coincides with both sides of the high speed driving at the same time, the high speed driving stops, and at this time, the far-end feeding table 4 is completely removed from the press, and the pressing operation is performed.

After the high speed driving is stopped by the sensor 49, the front stopper 45 is grounded to the second limit switch 47b, and becomes low speed. Is completed.

By repeatedly explaining the above-described operation, the conveyance of the fabric can be made more productive.

In addition, the sensor 107a is attached to the top plate 107 of the fabric sorter 100 so that when the fabric is not placed due to a malfunction of the adsorption means 10, the next operation does not proceed to instruct a worker in a dangerous situation. do.

The present invention absorbs the fabric by the adsorption means and transfers it to the fabric alignment by low speed and high speed transfer by the deceleration motor, and then perfectly aligns it by the alignment means and puts it into the press accurately so that mass production is possible. The quality can be improved and the safety of work can be increased.
