Description

  The present invention is a double-sided fold that allows a garment that has been put into the process in an almost constant figured state to be folded by selecting a chest fold in which the sleeve is folded back and a back fold in which the sleeve is folded in front The present invention relates to a corresponding folding device.

  For example, it has been implemented for a long time in the company to which the present applicant is concerned, and the so-called breast folding where the sleeves are folded back so that the chest of the clothing appears on the front and the sleeves are folded forward so that the clothing Conventionally, a device that can perform so-called back folding that folds so that the spine appears front is known. This device is convenient because it can deliver the above different folded products according to customer's request, but this type of device needs to match the processing speed with the front and back devices, in which case the slower one is always Since the speed is adjusted, there is a problem that the function of the corner cannot be used effectively. An example of this type of application is JP-A-8-323100.

  The clothing folding device has an ironing device called an ironer in the previous stage, and the clothing that is discharged from it is folded. However, if the ironer speed is too high, the moisture of the clothing cannot be removed sufficiently, and if it is too slow, it will be excessive. Since it becomes dry and the quality may be impaired by overheating in some cases, it is necessary to match the speed of the folding device with the speed of the ironer. In particular, in an apparatus that is used for both chest folding and back folding, the number of processes is increased, so that higher speed conveyance is required. Although it is not difficult to increase the processing speed for transporting and folding the clothes, the speeding up causes a problem that the clothes are likely to be disturbed.

JP-A-8-323100

  The present invention has been made paying attention to the above-mentioned points, and the problem is to provide a folding device that supports double-sided folding that can perform high-speed folding of chest folds and back folds without causing any disturbance in clothing. It is to be. Another object of the present invention is to provide a folding device that supports folding on both sides, which enables folding of different articles such as clothing and fabrics that have not been attempted.

In order to solve the above-mentioned problems, the present invention selects a chest fold in which sleeves are folded on the back and a back fold in which sleeves are folded on the front for clothes that have been put into the process in a substantially uniform state. About the folding device that can be folded and double-sided folding,
It is located immediately after the throwing conveyor and the pair of upper and lower conveyors that convey the thrown-in clothes and also serves as a sleeve folding part, and is positioned immediately after the throwing conveyor and sandwiches the clothes. A means is provided which comprises an upper conveyor section in which three sets of two-fold conveyors to be arranged are arranged, and a sleeve folding section which is installed in the input conveyor and performs sleeve folding.

  What is important in the above-described configuration of the present invention is that it includes a pinch conveyor composed of a pair of upper and lower conveyors that sandwich and convey the clothes, and does not destroy the shape of the clothes by conveying the clothes. This is a point that enables high-speed conveyance. The pinch conveyor consisting of a pair of upper and lower conveyors is arranged immediately after the input conveyor, thereby adjusting the transfer speed of the input conveyor to the previous process, and the pinch conveyor conveys clothing at a higher speed than the transfer speed of the input conveyor, It is possible to open an interval with the next clothes conveyed to the input conveyor. Then, it is possible to perform a certain operation on the input conveyor until the clothes reach the pinch conveyor where the clothes are conveyed at high speed, and the apparatus of the present invention performs sleeve folding at this portion.

  In the apparatus of the present invention, it is not limited as to whether the chest folding or the back folding is easily performed. It is common for clothes to be put into the loading conveyor in an upward-facing state from the ironer, but assuming this case, it is normal to perform a back-folding with the sleeves folded on the front on the loading conveyor. . This is because it is impossible to fold the sleeves on the back of the upward clothing. However, when the garment is thrown in a downward state, it is possible to perform a breast folding on which the sleeves are folded back on the throwing conveyor.

The present invention further provides a double-sided foldable garment that has been put into the process in a substantially uniform shape by selecting a chest fold in which the sleeves are folded back and a back fold in which the sleeves are folded forward. About folding device for folding
It is located immediately after the throwing conveyor and the pair of upper and lower conveyors that convey the thrown-in clothes and also serves as a sleeve folding part, and is positioned immediately after the throwing conveyor and sandwiches the clothes.

  The above-described configuration of the present invention is particularly suitable when being put into an input conveyor in an upward-shaped state from an ironer, performing sleeve folding for back-folding on the input conveyor, and breast-inversion after garment inversion The sleeves for chest folding are folded on the front conveyor. However, as described above, it is also possible to fold sleeves for chest folding on the input conveyor, and to fold sleeves for back folding after turning the clothing upside down.

  The above-mentioned middle conveyor section can be arranged immediately after the reverse exit of the intermediate conveyor, and includes a flat object discharge conveyor used when folding sheet-like cloths different from clothing. . In this way, it is possible to fold different articles such as clothing and fabrics that have not been attempted before.

  The final conveyor can be configured to include a vertical trifold portion for folding from the left and right sides of the folded garment after the back folding or chest folding. Thereby, the trunk | drum of the garment folded by the chest folded or the back folded can be folded in three, and can be made more compact.

  The final conveyor is configured to include a final folding conveyor located immediately below and at the bottom of the exit, and a final folding knife for performing final folding on the clothes that have been folded back or chest folded and vertically folded in three. Can be taken. As a result, the sleeve-folded chest folded or back folded and the garment with the trunk folded in three can be further folded in two to make it more compact.

  In the description so far, folding of clothing is described in the case where the garment is put on the loading conveyor in a posture in which the collar side precedes. However, the apparatus of the present invention is not limited to the direction in which clothes are put in, and it is possible to fold the clothes even when they are put into the putting conveyor in a posture where the hem side of the clothes precedes. is there. If the chest is folded when the garment is placed on the loading conveyor in a leading position, it can be carried out without any changes to the apparatus. In the present invention, the throwing method in the posture preceded by the collar side is called an ellipse insertion method, and the throwing method in the posture preceded by the hem side is called a soot insertion method.

  The present invention is configured and operates as described above, and since clothes are conveyed while being sandwiched between a pair of upper and lower conveyors, they can be conveyed at a higher speed than the input conveyor at the previous stage. At the same time, the clothes will not be disturbed even when transported at high speed, so the devices required for the sleeve folding part for chest folding and back folding are driven using the margin generated between the conveyors by high speed transportation. Therefore, it is possible to provide a folding device that supports folding on both sides according to the processing speed of an ironer or the like and that can be folded at a higher speed than conventional ones. In addition, according to the present invention, the use of the above-described apparatus and the addition of a single conveyor enables the folding of different articles such as clothing and cloth that have not been attempted so far. A folding device can be provided.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. Fig. 1 shows a garment in a uniform shape and put it into the process. The garment W in which the sleeve is folded on the back and the back fold in which the sleeve is folded on the front 1 shows an example of a folding device 10 that can be folded by selecting the two-sided folding according to the present invention. In the present invention, “upstream” means the side where the fabric W is input as a whole process, and “downstream” means the opposite side, and it does not relate to forward rotation or reverse rotation of the conveyor.

  In the figure, reference numeral 11 denotes an input conveyor that also serves as a fold-back folding sleeve fold. For example, the input conveyor 11 conveys the garment W discharged from the previous process ironer and input to the process by the apparatus 10. Like other conveyors, it has at least two conveyor rolls at both ends, and has a structure in which a plurality of conveyor belts are wound around them. Moreover, the input conveyor 11 is equipped with a back folding sleeve folding part 12 along the conveyor belt for the case of performing back folding.

  The above-described fold-back folding sleeve fold portion 12 is positioned higher so as not to obstruct the movement of the garment W as shown in FIGS. 3 and 4, and is substantially spaced from the base of the sleeve. It has a pair of gauge rods 13 and 13 arranged by. In addition, a pair of sleeve folding folds 14, 14 are provided between the conveyor belts located slightly outside the pair of gauge folds 13, 13 and can move up and down and move in the left-right direction so as to narrow or widen the interval. Yes. Therefore, the cloth W which does not carry out back folding passes through this part.

  Immediately after the input conveyor 11, a pinch conveyor 17 including a pair of upper and lower conveyors 15 and 16 that convey the clothes W is positioned. The upper conveyor 15 is shorter than the lower conveyor 16, and the upper conveyor 15 and the lower conveyor 16 have substantially the same end position on the clothing entry side, and the upper conveyor 15 end 15a on the clothing entry side is lifted. Open (see FIG. 3) to facilitate the entry of the garment W. The lower conveyor 16 is arranged farther from the downstream folding conveyor 18 than the upstream conveyor 11, and the first folding knife 21 having a tip entering toward the gap 19 is arranged at the upper side. Has been.

  These three sets of conveyors 11, 17, 18 constitute an upper conveyor section 20, and the upper conveyor 20 is also sufficiently high with respect to the clothes discharge speed from the ironer in the previous process, that is, pulling force on the clothes Can be transported to work. And in this high-speed conveyance, the pinch conveyor 17 which consists of a pair of upper and lower conveyors 15 and 16 prevents the clothing W from being disturbed by carrying the clothing W in between. In particular, it is assumed that the sandwiching conveyor 17 can be operated at a speed sufficiently higher than the conveying speed of the input conveyor 11 and that the speed can be changed according to the clothes discharging speed from the ironer. The input conveyor 11, the sandwich conveyor 17 and the two-fold conveyor 18 are arranged linearly in a generally upward tendency toward the downstream. Since this inclination acts suppressively on the garment W to be transported, it is effective in preventing the garment W from being disturbed without giving momentum during the high-speed transport.

  In the figure, reference numeral 22 denotes a loading conveyor drive motor, and 23 and 23 ′ denote pinch conveyor drive motors, which are installed vertically to drive the upper conveyor 15 and the lower conveyor 16 of the pinch conveyor 17. The downstream folding conveyor 18 is driven by a drive motor 24 so as to be able to rotate forward and backward. The upstream end 18a of the bi-fold conveyor 18 takes a slightly lower position than the outlet end 16a of the lower conveyor 16 of the pinch conveyor 17, and an upstream end 27a and a flat object of the intermediate conveyor 27 described later. It is provided so as to approach the upstream end 31 a of the discharge conveyor 31. Also, blowers 25a and 25b for injecting air to the clothing are installed above the upstream end 18a of the folding conveyor 18 and below the outlet end 16a of the sandwich conveyor lower conveyor 16, respectively. Has been.

  An intermediate conveyor 27 is installed below the upper conveyor section 20. The intermediate conveyor 27 is in a position to receive the clothes W folded downward by the first folding knife 21 from the gap 19 between the sandwiching conveyor 17 and the end of the two-fold conveyor, and is provided so that it can be rotated forward and backward by the intermediate conveyor drive motor 34. ing. The illustrated intermediate conveyor 27 has a downward inclination from the upstream end 27a close to the upstream end 18a of the double fold conveyor 18 toward the downstream end 27b close to the chest conveyor 33 described later. It is formed in a triangular shape on the side, the downwardly inclined portion is the upper conveying surface 28, the bottom portion is the lower conveying surface 29, and the lower conveying surface 29 is at the boundary between the chest conveyor 33 and the lower conveyor 40. , Straddling both.

  A flat object discharge conveyor 31 having an upstream end 31a close to the upstream end 27a of the intermediate conveyor 27 is arranged in front of and behind the intermediate conveyor 27. These two sets of intermediate conveyor 27 and flat object discharge The intermediate conveyor section 30 is configured by the conveyor 31. The flat object discharge conveyor 31 is located immediately after the reverse rotation outlet (upstream end 27a) of the intermediate conveyor 27, and is used when folding sheet-like cloths different from clothes. The flat object discharge conveyor 31 is driven using a drive motor 23 '.

  Below the intermediate conveyor 27 is a position for receiving the garment W at the normal rotation outlet (downstream end 27 b) of the intermediate conveyor 27, and the chest that forms a part of the chest folding sleeve folding part 32. A partial conveyor 33 is installed. The chest conveyor 33 has a slightly gentle inclination in the same direction as the inclination of the intermediate conveyor 27, and the end of the conveyance surface on the entrance side during normal rotation reaches the lower part of the lower conveyance surface 29 of the intermediate conveyor 27 and overlaps. In addition, an end portion on the inlet side of a final conveyor 38, which will be described later, which overlaps the lower conveying surface 29 in the same manner, communicates with each other so that the clothes W can be discharged and entered smoothly.

  As shown in FIGS. 6 and 7, the chest folding portions 32 for breast folding are arranged at the upper portion of the sleeve at the upper position so as not to obstruct the movement of the clothing W. A pair of gauge rods 35, 35 are provided above the chest portion conveyor 33. Further, a pair of sleeve folds 36, 36 that can move up and down and move left and right between the conveyor belts located slightly outside the pair of gauge ridges 35, 35 are arranged in the chest. The chest folding sleeve folding part 32 is provided above the conveyor 33, and includes a pair of breast feeding part conveyors 33, 33 and sleeve folding bars 36, 36. Reference numeral 37 denotes a chest conveyor driving motor.

  A final conveyor 38 is installed immediately after the chest conveyor 33 and at a position where it cooperates with the lower transport surface 29 that is a part of the intermediate conveyor 27 in order to send and receive the garment W sent by the reverse rotation of the intermediate conveyor 27. Yes. That is, the garment W can move from the end of the chest conveyor 33 to the final conveyor 38 in the range of the lower conveyance surface 29 that is a part of the intermediate conveyor 27. Furthermore, at the normal rotation outlet (downstream end 27b) of the intermediate conveyor 27, a protruding position for guiding the garment W to the final conveyor 38 at the time of folding back and a retracted position for guiding it to the chest conveyor at the time of chest folding are taken. A second folding knife 39 is provided. The two sets of the chest conveyor 33 and the final conveyor 38 constitute a lower conveyor section 40. The second folding knife 39 takes the retracted position shown in FIGS. 11 and 12 to guide the cloth W toward the final conveyor 38 when the chest folding is not performed.

The final conveyor 38 includes a vertical trifold portion 41 for folding the folded garment that has finished the back folding or chest folding from the left and right (see FIGS. 8 and 9). The vertical trifold portion 41 has a central conveyor 42 and left and right conveyors 43 and 44 arranged in parallel,
The central conveyor 42 supports the central part of the garment W and is installed at a position lower than the left and right conveyors 43 and 44, and both side parts of the garment W are supported by the left and right conveyors 43 and 44. A vertical tri-fold gauge 45 narrower than the conveyor 42 is installed at a position lower than the central left and right conveyors 43 and 44 at a position above the central conveyor 42 and the movement of the clothing W is taken into consideration. The vertical tri-fold gauge 45 has a front end 45a formed in an arc shape so that it does not get in the way. Thus, the folded garment W that has finished the back folding or chest folding is folded from the left and right (vertical trifold).

  The final conveyor 38 includes a final folding conveyor 46 positioned immediately after and at the bottom of the exit, and a final folding knife 47 that performs final folding on the clothes W that has been folded back or chest-folded and vertically folded in three. (See FIG. 9). The final folding knife 47 further folds the garment W that is not discharged from the discharge plate 48 disposed at the outlet of the final folding conveyor 46, and a drop plate that is a double-opening type opening / closing plate between the lower surface 49 of the final conveyor 38. It is also a means to send to 50. Reference numeral 51 denotes a clothes receiving and discharging conveyor, 52 denotes a driving roller thereof, and 53 denotes a longitudinal folding conveyor driving motor. Reference numeral 54 denotes an ironer corresponding to the preceding process, 55 denotes an upper sensor, 56 denotes a chest sleeve folding sensor, and 57 denotes a back sleeve folding sensor.

Next, folding performed by the folding device 10 corresponding to the double-sided folding of the present invention configured as described above will be described. In order to use the apparatus 10 of the present invention, the chest folding mode is first selected by an operation on a control panel panel (not shown).
<Chest fold>
The folding procedure in the chest folding is shown in FIG. 2, and symbols I to VII added to FIG. 2 correspond to the positions of symbols I to VII described in the respective positions in FIG. The clothes W are discharged from the ironer 54 at a predetermined speed, and are put into the feeding conveyor 11 and conveyed in an upward state and a substantially constant shape (FIG. 3). At this time, since the back folding sleeve folding part 12 is retracted to the upper and lower positions of the conveyor conveying surface, the clothing W passes through as it is and enters the pinch conveyor 17 to detect the entry by the upper sensor 55 (FIG. 4). . When the entry of the clothes W is detected, the conveyance speed of the pinch conveyor 17 is increased at that time, and the conveyance speed of the input conveyor 11 is maintained, so that the clothes W are pulled so as to open a gap.

  When the garment W conveyed by the pinch conveyor 17 approaches the outlet end 16a of the lower conveyor 16, the first folding knife 21 is switched to the lowered position by selecting the breast folding mode (FIG. 5). Since the front end of the garment W is guided to the gap 19 between the lower conveyor 16 and the two-fold conveyor 18, the garment W changes its conveying direction and is turned over, and enters the intermediate conveyor 27 that normally rotates in the direction of the arrow in FIG. To do. The garment W then enters the thorax conveyor 33 from the upper conveying surface 28 of the intermediate conveyor 27 (FIG. 6B), and when it is detected by the thorax sleeve folding sensor 56, it folds instantly at a fixed position and in the reverse direction. Change to transport. At that short time, the chest folding sleeve folding part 32 is activated (FIG. 7A), so that the sleeve is folded by the sleeve folding collar 36 with the gauge collar 35 on the back of the garment W turned upside down. It will be in a state and will be sent to the following vertical tri-fold part 41 by the reverse breasting part conveyor 33 (FIG. 7B).

  The garment W is turned upside down and enters the vertical trifold portion 41 in a breasted state (FIG. 8), with its central portion resting on the central conveyor 42 and its left and right sides resting on the left and right conveyors 43 and 44, respectively. Stop. Next, it enters the lower part of the vertical tri-fold gauge 45 that has been waiting on the upper side, and the central part of the garment W is pressed against the central conveyor 42, and accordingly, it is arranged at the level difference between the central conveyor 42 and the left and right conveyors 43, 44. The left and right sides of the garment W are folded inwardly as shown by the arrows shown in FIG. 9 by known folding means such as a folding plate that can be moved in the left-right direction, so that the garment W is turned over. It folds and overlaps with the central part of the back surface to be in a vertically trifold state (FIG. 10A). The garment W folded vertically in the breasted state is folded in half by the final folding knife 47 (FIGS. 10B and 11) and sent to the next process.

Clothes WA (see VII in FIG. 2) folded vertically and finally folded in the breasted state is sent from the final folding conveyor 46 to the drop plate 50 (FIG. 12). The dropping plate 50 is of a double-opening type, and when the pair of dropping plates 50, 50 are quickly opened downward and to the left and right, the clothes W placed thereon lose support and fall onto the clothes receiving and discharging conveyor 51 (see FIG. 13).
Next, the back folding performed by the apparatus 10 of the present invention will be described. Also in this case, the back folding mode is selected by an operation on the control panel panel (not shown).

<Back fold>
The folding procedure in the back folding is shown in FIG. 15. Reference numerals I to VIII added to FIG. 15 correspond to the positions of reference signs I to VIII described in the respective positions in FIG. The garment W discharged from the ironer 54 at a predetermined speed is input to the input conveyor 11 and conveyed in an upward state and a substantially constant shape. When this is detected by the back sleeve folding sensor 57, the back folding sleeve folding portion 12 is activated at a preset sleeve folding timing. That is, the gauge rod 13 retracted to a position above the conveyor conveyance surface descends and presses near the base of the sleeve of the garment W (FIG. 17A), while the sleeve folding rod 14 retracts below the conveyor conveyance surface. And the left and right sleeves are folded back inward by moving inward (FIG. 17B), and the sleeve folding for back folding is completed here. When the garment W after folding the sleeve enters the sandwiching conveyor 17, the upper sensor 55 detects the entry (see FIG. 19). When the entry of the clothing W is detected, the conveyance speed of the pinch conveyor 17 is increased at that time, so that the space between the clothing W and the next clothing W is pulled open, and the time generated thereby is used to perform the folding operation. And so on.

  The garment W being conveyed by the pinch conveyor 17 starts to be transferred to the bi-fold conveyor 18 beyond the outlet end 16a of the lower conveyor 16, and an arbitrary part of the overall length of the garment is formed between the lower conveyor 16 and the bi-fold conveyor 18. When approaching the gap 19, the first folding knife 21 is lowered by the timer signal after detection by the upper sensor 55 and the two-fold conveyor 18 is reversed, so that the garment W is folded at the arbitrary position and the folding is performed. It is folded into a gap 19 between the lower conveyor 16 and the two-fold conveyor 18 from the location. Here, the garment W changes its direction of conveyance and is folded in half, and enters the intermediate conveyor 27 that normally rotates in the direction of the arrow in FIG. 1 (FIG. 20). The garment W further travels on the upper conveying surface 28 of the intermediate conveyor 27 (FIGS. 21B and 22), and once it moves onto the breast conveyor 33 and changes over, the breast conveyor 33 changes to reverse (FIG. 23). The garment W that has been folded back and folded in half and shorter than the overall length of the garment is then sent to the next vertical tri-fold section 41 by the reverse breasting section conveyor 33. Is the same as in the above-described chest-folded garment W. The time generated by the high-speed conveyance of the pinch conveyor 17 is used for the direction change from the chest conveyor 33 to the next vertical tri-fold 41, the vertical tri-fold, and the change in the conveyance direction during the bi-fold. The

  That is, as will be understood with reference to FIG. 8 and subsequent figures, the garment W is turned upside down and enters the vertical trifold portion 41 in a straight-out state (FIG. 8). Therefore, the vertical tri-fold gauge 45 presses the central portion of the garment W against the central conveyor 42, and the known folding means arranged at the height difference between the central conveyor 42 and the left and right conveyors 43, 44 causes the arrow shown in FIG. Thus, the left and right sides of the garment W are folded inward, so that the left and right sides of the garment W are folded inward to form a vertically trifolded state (FIG. 10A). Clothing WB (see VIII in FIG. 15) vertically folded in the unfolded state is folded in half by the final folding knife 47 (FIGS. 10B and 11), and dropped from the drop plate 50 onto the clothes receiving and discharging conveyor 51. (FIG. 13).

  The folding device 10 for double-sided folding according to the present invention folds the clothing W into the chest and back-up states as described above, but uses the basic configuration of the device 10 and adds one conveyor 31. By doing so, it is possible to fold not only clothing W including a yukata and gown, but also other fabrics S such as sheets called flat objects. That is, the present invention enables folding of different varieties, such as clothing W and fabric S, which has never been implemented.

  FIG. 24 is an explanation relating to the flat folding of a flat object, and a point at which a half of the transport direction length of the cloth S transported on the sandwiching conveyor 17 comes between the sandwiching conveyor 17 and the two-fold conveyor 18. In (Process I), the cloth S is folded in two by rotating the first folding knife 21 toward the gap 19 and reversing the bi-fold conveyor 18 (Process II). The cloth S folded in half is moved to the middle conveyor section 30 (process III) and conveyed until a half of its length in the conveying direction is between the intermediate conveyor 27 and the flat object discharge conveyor 31. At that time, the intermediate conveyor 27 is reversed and air is blown from the blowout 26 to fold the fabric S between the end portions 18a and 31a and fold it again (step IV). It can send out to the discharge conveyor 31 (process V).

  FIG. 25 is an example in which a flat object is folded in half, and the clothes W are conveyed by the pinch conveyor 17 (step I), and when the leading edge of the cloth S comes between the pinch conveyor 17 and the double fold conveyor 18, The cloth S is guided to the gap 19 by pushing the fold conveyor 18 in the reverse direction, and pushed in (step II). The pushed-in cloth S moves to the middle conveyor section 30 (step III) and is transported until a half of its transport direction length is between the intermediate conveyor 27 and the flat object discharge conveyor 31. At that time, the intermediate conveyor 27 is reversed and air is blown from the blowout 26 to fold the cloth S between the end portions 18a and 31a and fold it into a folded state (step IV). It is sent out to the conveyor 31 (process V).

  The folding device 10 for double-sided folding according to the present invention can fold the clothing W into the chest and back-up states as described above, and not only the clothing W including a yukata and a gown. It is possible to fold other cloth S such as a sheet called a flat object. As can be inferred from the above fact that a sleeve can be folded or not, according to the apparatus 10 of the present invention, a posture preceded by the collar side, which is referred to as the erection method described so far. Since the garment W put in the posture of the sash insertion method preceded by the hem side can be folded, the folding method will be described with reference to FIG.

<Chest fold>
FIG. 26 and subsequent figures show a folding procedure in the chest folding for the garment W that has been put into the process by the soot insertion method. The clothes W are discharged from the ironer 54 at a predetermined speed, and are put into the loading conveyor 11 and conveyed in a substantially constant shape and downward state (FIG. 26). In folding in the soot insertion method, the back folding sleeve folding section 12 is activated and the sleeve is folded in the same manner as the back folding. That is, when the clothing W is detected by the back sleeve folding sensor 57, the back folding sleeve folding portion 12 is activated at a preset sleeve folding timing and is retracted to a position above the conveyor conveyance surface. The gauge rod 13 descends and presses near the base of the sleeve of the garment W (FIG. 27), while the sleeve folding rod 14 retracted below the conveyor transport surface rises and moves inward to move the left and right sides. The sleeve is folded inward (FIG. 27), and the sleeve folding for the chest folding is completed here.

  When the garment W enters the pinch conveyor 17 after folding the sleeve, the upper sensor 55 detects the entry (see FIG. 4). When the entry of the clothing W is detected, the conveyance speed of the pinch conveyor 17 is increased at that time, so that the space between the clothing W and the next clothing W is pulled open, and the time generated thereby is used to perform the folding operation. This is the same as the previous explanation. It should be noted that, in the chest folding in the soot insertion method, the subsequent steps are performed in the same manner as in the back folding in the collar insertion method, and the clothes W conveyed by the pinch conveyor 17 are on the outlet side of the lower conveyor 16. When it starts to be transferred to the bi-fold conveyor 18 beyond the end 16a and an arbitrary portion of the overall clothing approaches the gap 19 between the lower conveyor 16 and the bi-fold conveyor 18, a first timer signal is detected by the upper sensor 55 after detection. The folding knife 21 descends and the two-fold conveyor 18 changes to reverse rotation, and the garment W is folded at an arbitrary position, and is folded into a gap 19 between the lower conveyor 16 and the two-fold conveyor 18 ( FIG. 28).

  Here, the clothing W changes its direction of conveyance and is folded in half, and enters the intermediate conveyor 27 that normally rotates in the direction of the arrow in FIG. The clothing W further travels on the upper conveyance surface 28 of the intermediate conveyor 27, but unlike the back-folding folding in the collar putting method, the clothing W does not proceed to the chest conveyor 33 and exits at the normal conveyor 27 (downstream). The second folding knife 39 descending to the position of the side end portion 27b) is sent to the next vertical trifold portion 41 together with the breast feeding portion conveyor 33 which is reversed (FIG. 29). The subsequent operation on the garment W that is chest-folded and is folded in half so as to be shorter than the overall length of the garment is the same as that in the above-described breast-folded garment W.
