[0005] Conventionally known folding apparatuses are provided with a conveyor 11, a folding conveyor 12, and a folding knife 16 for pushing cloths toward a fold 13. In this case, the apparatus according to the present invention is configured by installing the minimum standby conveyor 14 at an appropriate position and installing the guide member 15 for guiding the cloths thereto.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The apparatus according to the present invention is an apparatus for stacking cloths and folding the cloths in that state.

A conveyor 1 is used as a means for conveying cloths.
1 is provided. The cloth is conveyed from the input side at one end to the exit side at the other end. The fabric is similarly fed to the loading side, whether it is down or up. In the illustrated embodiment, the transport conveyor 11 has a transport surface that is low on the input side and gently inclined. The transport surface is composed of a number of belts, and a guide member 1 described below is interposed between the belts.
There is a gap where 3 can be arranged.

An interval at which the cloth W can be conveyed by the conveyor 11 is provided above the outlet side of the conveyor 11.
A standby conveyor 12 is provided. A portion on the front side of the conveyor 11 where the standby conveyor 12 is not provided is a space S into which the cloth is put. The standby conveyor 12 is a means for stacking two cloths W, W in a separated state.

The standby conveyor 12 is disposed above the outlet side of the conveyor 11 and its outlet end 18 projects rearward from the outlet end 17 of the conveyor 11. This is to prevent the upper cloth W hanging down from the outlet end 18 of the standby conveyor 12 at the upper position from contacting the lower cloth W. The illustrated standby conveyor 12 has a transport surface that is substantially parallel to the transport conveyor 11.

As another means for separating the upper and lower cloths W, W, a separator 19 is provided. Exemplary separator 19
Is provided at the lower part of the lower exit end 17 so as to be able to move back and forth. The separator 19 is pivotally supported at the lower end, and has a structure in which the upper end moves back and forth under the insertion opening 14. In the case of the moving system, either the swinging shown in FIG.

In order to guide the cloth to the standby conveyor 12, a guide member 13 for scooping the cloth while the conveyor 11 is moving is provided. The guide member 13 has a projecting position on the conveyor 11 that provides a gentle slope that can be lifted by sliding the cloth, and a immersion position that allows the moving cloth to pass through as it is.

The illustrated guide member 13 is composed of a required number of guide pieces arranged between a number of belts, and has a structure in which the lower ends thereof are attached to the shaft 21 and can be protruded and retracted by the rotation of the shaft 21. Have. However, the guide member 13 may be pivotally supported at the upper end, and this is shown in FIG. 9 as a modification. FIG. 9 also shows an example in which two stages of standby conveyors 12 are provided, whereby three sheets can be stacked. In this case, the outlet end 18 'of the upper standby conveyor 12' protrudes rearward from that of the lower standby conveyor 12 ', and the separator 19' and the guide member 13 'are additionally provided.

A folding conveyor 15 is disposed at a lower portion 12 on the exit side of the conveyor 11. The entrance end of the conveyor 15 substantially overlaps with the exit end 17 of the conveyor 11, and the space between the entrance and exit forms a fold 14 for the cloth. A folding knife 16 for pushing the cloth W toward the folding opening 14 is provided. The folding knife 16 is the standby conveyor 1
Since the cloth W hanging down from 2 is pushed over the lower cloth W, the cloth W can be moved back and forth. The back-and-forth movement may be a circular movement in the illustrated example or a linear movement.

In the case of the embodiment, the folding conveyor 15 is set to have a lower slope in the downstream. The outlet end 22 forms a two-fold cloth outlet between itself and the lower roll 23 of the conveyor 11. Further, a second folding conveyor 25 and a second folding knife 26 for performing the second folding are provided in a direction opposite to the conveying direction toward the lower second folding opening 24. 27 is a guide roll, which turns the lower part of the upper folding conveyor 15 to the second
A folding means is formed which enables the second folding with the folding conveyor 25.

In each figure, A is a first sensor provided on the loading side of the conveyor 11, B is a second sensor provided on the exit side,
C indicates a third sensor provided on the standby conveyor 12, and D and E indicate fourth and fifth sensors provided on the folding conveyor 15. An encoder 28 for measuring the length of cloth is provided on the loading side of the conveyor 11. The operation of each section is switched depending on whether the cloth is the first sheet or the second sheet. The control and the processing of signals from the sensors A to E are performed by a control device (not shown).

[0016] With the device having such a configuration, the cloths are folded and folded as follows. To explain the double stack,
1 sheet of cloth W ₁ is derived standby conveyor 12 F by the guide member 13 that protrudes (Fig. 1). Then cloth W ₁
Is turned on, the third sensor C is turned on, and then, for example, a half of the length in the transport direction passes, and the standby conveyor 12 stops in a state where it hangs down from the outlet end 18 to stop the guide member 13.
Also switches to the closed state (FIG. 2).

The length of the _second cloth W ₂ is measured by the first sensor A and the encoder 28 (FIG. 3).
1 toward the exit side. Is grasped passes by the second sensor B, sag from the outlet end 17, cloth W ₁ of the first sheet and the second sheet of cloth W ₂ at the timing when the overlapping state object, waiting conveyor 12 is activated . This timing can be arbitrarily adjusted. The two hanging cloths W ₁ and W ₂ are separated by a separator 19 (FIG. 4). Conveyor 11 transports the _first cloth W1
The same applies when the second cloth W ₂ is passed through the standby conveyor 12.

The two cloths W ₁ and W ₂ thus overlapped with each other have a length of 2 based on the length measurement data of the _second cloth W 2.
The folding knife 16 is folded in half by the operation of folding the half position into the insertion opening 14 (FIG. 5). The bi-folded cloths entering the middle-stage bi-fold conveyor 15 are measured by the operation of the fourth and fifth sensors D and E (FIG. 6), and the second folding knife 26 operates based on the length measurement data there. I do. As a result, the cloths W ₁ and W ₂ are again folded in _two, are folded into four, and are discharged from the second folding conveyor 25 (FIG. 7).

The first folding knife 16 is operated at one third of the length of the reference cloth in the transport direction (length of cloth), and the second folding knife 26 is operated. When operated for two-thirds of the points, the two cloths W ₁ and W ₂ can be folded in three. Further, if the operation mode is such that the guide member 13 and the standby conveyor 12 are not used, it is possible to fold one sheet at a time.

[0020]

The cloth folding apparatus according to the present invention is constructed and operates as described above.
When the guide members 13 are fed into the conveyor 11 one by one,
Cloth W ₁ of the first sheet, for example, by the standby conveyor 12
F, the second cloth W ₂ advances on the conveyor 11 and hangs down at the exit end of each of the conveyors.
Since _1, W knife 16 folded relative to the intermediate point such as the desired folding position of the ₂ folded, an effect that can be folded while overlapping a plurality of cloth. Such an apparatus of the present invention includes a standby conveyer 1 in a single cloth folding apparatus.
2 and the guide member 13 are added, and their operation is controlled by a sensor, an arithmetic unit, and the like, so that the implementation is easy.
