Description

  The present invention relates to linen equipment. More specifically, the present invention relates to a linen facility for ironing and folding cloths such as washed towels and sheets.

A large amount of towels, sheets, clothing, and other cloths are used in hotels and hospitals, and the used cloths are collected, washed, ironed and folded in a laundry factory, and transported to hotels and hospitals again. It is common to be used there.
One of the linen facilities installed in a laundry factory is a set of a charging machine, a roll ironer, and a folding machine (for example, Patent Document 1). As shown in FIG. 8, the linen equipment is connected to the exit side of the roll ironer 112 on the exit side of the input device 111 and connected to the entrance side of the folding machines 113 and 114 on the exit side of the roll ironer 112. A processing line is formed by the apparatus. When the washed fabric is put into the throwing machine 111, it is adjusted to a slender figure, ironed by the roll ironer 112, and folded by the folding machines 113, 114.

In the conventional linen equipment, a large distance D is provided between the charging machine 111 and the roll ironer 112 and between the roll ironer 112 and the folding machine 113. The distance D is actually about 1 to 2 m, and this length is necessary even for a long cloth such as a sheet. This is because a discharge mechanism for ejecting is provided.
Generally, the discharge mechanism is configured to be able to swing the conveyor downward so that the cloth is dropped downward.

As described above, since the charging device 111 and the roll ironer 112 are arranged apart from each other, the conventional linen equipment has a problem that it has a long overall length and takes a place for installation.
In addition, since the cloth needs to pass through a long linen facility, there is a problem that the time required for the treatment becomes long and the treatment speed per cloth is slow.
Therefore, as a result of the inventor's ingenuity, the inventor completed a completely new layout in which the interval between the feeding machine and the roll ironer was shortened and the roll ironer and the folding machine were combined and arranged. Filed as 894.
With this new layout linen equipment, the installation space can be small, and the processing speed of cloth can be increased.

However, as described above, when the interval between the charging machine and the roll ironer becomes narrow, it is not possible to install a mechanism for discharging defective fabrics in which the dressed state is broken as in the prior art.
However, sending defective fabrics directly to the roll ironer or further to the folding machine will cause failure, and it will take time and labor for manual inspection and removal in the final process, thus hindering productivity. .

The rear pressing belt 36 is provided so as to go around its outer periphery in synchronization with the rotation of the rear heating roll 12. The rear pressing belt 36 has a start end disposed near the front upper side of the rear heating roll 12, and is wound around the rear heating roll 12 in the order of the upper side, the rear side, and the lower side. It is arranged on the lower side. Therefore, the rear pressing belt 36 is wound over approximately 3/4 of the outer periphery of the rear heating roll 12. The rear end portion of the rear pressing belt 36 is connected to the start end portion of the third conveyor 33.

  The fabric C conveyed by the second conveyor 32 moves according to the rotation of the rear heating roll 12 while being sandwiched between the rear heating roll 12 and the rear pressing belt 36. At this time, the cloth C is pressed against the rear heating roll 12 by the rear pressing belt 36, and the wrinkles are stretched by the heat and steam of the rear heating roll 12.

The 3rd conveyor 33 and the 4th conveyor 34 are arrange | positioned between the front heating roll 11 and the back heating roll 12, and the cloth C passed from the back pressing belt 36 is sent to the 3rd conveyor 33 and the 4th conveyor. It is comprised so that it may pinch | interpose and convey to 34, and it may guide to the front heating roll 11. FIG. Terminal portions of the third conveyor 33 and the fourth conveyor 34 are connected to the rear upper side of the front heating roll 11.
For this reason, the fabric C in which the wrinkles are extended by the rear heating roll 12 is conveyed to the front heating roll 11 by the third conveyor 33 and the fourth conveyor 34.

The front heating roll 11 has a high surface, and steam is jetted from the inside toward the outside. Further, the front heating roll 11 rotates counterclockwise.
The front pressing belt 35 is provided so as to go around its outer periphery in synchronization with the rotation of the front heating roll 11. The front pressing belt 35 has a start end portion disposed near the rear upper side of the front heating roll 11, and is wound around the front heating roll 11 in the order of the upper side, the front side, and the lower side. It is arranged on the lower side. Therefore, the front pressing belt 35 is wound over approximately 3/4 of the outer periphery of the front heating roll 11. Further, the end portion of the front pressing belt 35 is led to the starting end portion of the introduction conveyor 39.

  The cloth C conveyed by the third conveyor 33 and the fourth conveyor 34 moves according to the rotation of the front heating roll 11 while being sandwiched between the front heating roll 11 and the front pressing belt 35. At this time, the cloth C is pressed against the front heating roll 11 by the front pressing belt 35, and the wrinkles are stretched by the heat and steam of the front heating roll 11.

  The upper discharge conveyor 46 is a conveyor configured to convey a pair of cloths between a pair of conveyors 46a and 46b. The upper discharge conveyor 46 is characterized in that it is arranged to convey the cloth upward. That is, because the front heating roll 11 and the front pressing belt 35 exist below the first conveyor 31, there is no space for discharging defective fabrics downward from the first conveyor 31. .

  The side discharge conveyor 48 is composed of a single conveyor, and discharges the fabric C received from the upper discharge conveyor 46 to the side (front or back in the drawing). The cloth C discharged out of the system by the side discharge conveyor 48 is removed from the system or untangled, and is fed again from the feeder 1.

As shown in FIG. 1, the folding means 41 is disposed approximately at the middle of the total length of the first conveyor 31 and the second conveyor 32.
If the defective fabric is sandwiched between the tip of the second conveyor 32 and the guide conveyor 37, the defective fabric can no longer be discharged.
In the installation position, even the longest sheet C can be fed into the upper discharge conveyor 46 by operating the folding means 41 until the tip reaches the tip of the second conveyor 32. .

When the dosing machine 1 shown in FIG. 4 is putting cloth C, when the cloth C is tangled or a pillow is taken in, the detector 21 in the throwing machine 1 outputs a detection signal. Further, the length of the cloth C fed on the conveyor is measured by the length detector 25. When the length of the cloth C is known by the measurement of the length detector 25, the air cylinder 44 of the folding means 41 is extended after a predetermined delay time has elapsed after the detector 21 transmits a signal.

  As shown in FIG. 2B, when the air cylinder 44 contracts, the folding lever 42 swings counterclockwise and the insertion plate 43 pushes up near the center of the cloth C, so that the pair of conveyors 46a, 46b Push in between. The pushed-in cloth C is sandwiched between the pair of conveyors 46 a and 46 b and sent upward, and further sent to the side discharge conveyor 48. Defective fabrics thrown into the side discharge conveyor 48 are discharged out of the system.

As described above, since the cloth C, which is a defective cloth, can be discharged out of the system, only the cloth in a normal state can be fed into the roll ironer 2 and the folding machine 3.
