Description

[Technical field]

[0001] The present invention relates to a fabric light projecting device that projects light onto fabrics before the fabrics are fed into a fabric processing device, and to a fabric processing device having the fabric light projecting device. [Background technology]

[0002] The cloth products handled in the so-called linen supply industry include linen products such as sheets and towels, and when these linen products and other cloth products are collected from customers, they are washed, ironed, folded, and then delivered to the customers. At that time, workers pick up the cloth products one by one from the state where multiple washed cloth products are in a pile, and feed them into a cloth processing device that transports them to the next process to be further spread and folded.

[0003] However, there are cases where the inserted cloth material becomes misaligned on the transport conveyor in the cloth processing device, and JP 2018-117732 A discloses a method for detecting such misalignment.

[0004] In the above invention, when the positional deviation of the inserted cloth on the conveyor is detected, the worker must remove the inserted cloth from the cloth processing device, and then accurately insert the removed cloth back into the cloth processing device again, which is extremely inconvenient.

[0005] In particular, in recent years, there are cases where the customer's mark or trademark is affixed to the cloth, and the position of the mark when the cloth is folded becomes an issue. For example, if the customer's mark is positioned at the center of the cloth in an unfolded state, it is required that the mark be positioned at the center of the folded cloth even when the cloth is folded, but the problem of the mark being misaligned occurs.

[0006] When the fabric is folded in this manner, the mark must be placed at the position desired by the customer, and the worker is required to accurately feed the fabric into the fabric processing device. [Prior art documents] [Patent documents]

BEST MODE FOR CARRYING OUT THEINVENTION

[0017] The fabric light projector 10 will be described below with reference to the illustrated embodiment. The fabric light projector 10 has a light projecting unit 20. The light projecting unit 20 projects a light beam R1 onto a predetermined position T1 of the fabric W. The width direction H of the fabric processing device 500 refers to the direction of the width of the fabric processing device 500 indicated by the symbol H in a plan view of the fabric processing device 500 (see FIG. 2, for example).

[0018] The light beam R1 emitted by the fabric light projector 10 indicates a predetermined position T1, which is an arbitrary position in the width direction H of the fabric processing apparatus 500 described later. The fabric light projector 10 projects the light beam R1 indicating the predetermined position T1 onto the fabric W before the fabric W is fed into the fabric processing apparatus 500. That is, the worker prepares to feed the fabric W into the fabric processing apparatus 500 so that the light beam R1 indicating the predetermined position T1 coincides with the mark M on the fabric W, and thereby the worker can place the mark M on the folded fabric W1 at the desired predetermined position T3 desired by the customer, as described later (see FIG. 11).

[0019] For example, when a customer requests a so-called French fold in which both ends of the fabric W are folded inward and folded in thirds, the customer may request that the mark M exposed on the surface of the French-folded fabric W1 be placed at the center of the French-folded fabric W1 (desired predetermined position T3). In this case, if the center position in the width direction H of the fabric processing device 500 is set as the second predetermined position T2 and the mark M of the spread-out fabric W is placed at the second predetermined position T2, the mark M of the French-folded fabric W1 will be placed at the center when the fabric is French-folded. That is, by placing the mark M of the spread-out fabric W at the second predetermined position T2 in the width direction H of the fabric processing device 500 in the fabric processing device 500, the mark M of the French-folded fabric W1 will be placed at the desired predetermined position T3 desired by the customer. Here, the second predetermined position T2 is indicated by the second light beam R2 irradiated by the second light projecting unit 100 described later.

[0020] Therefore, the light projecting unit 20 of the fabric light projecting device 10 projects a light beam R1 indicating a predetermined position T1 on the fabric W as a predetermined position T2 in the width direction H of the fabric processing device 500 before the worker puts the fabric W into the fabric processing device 500. By projecting the light beam R1 on the predetermined position T1 of the fabric W before putting the fabric W into the fabric processing device 500 in this way, the worker prepares to put the fabric W in so that the mark M of the fabric W is located at the predetermined position T1, and puts the fabric W in the fabric processing device 500 in this state and folds it. For example, the position of the mark M of the French-folded fabric W1 is placed at the desired predetermined position T3 desired by the customer. The predetermined position T1 pointed to the fabric W and the second predetermined position T2 in the width direction H of the fabric processing device 500 coincide with each other in the width direction H of the fabric processing device 500. The desired position T3 is an arbitrary position in the width direction H1 of the folded cloth W1 (see FIG. 11B). In this case, the desired position T3 desired by the customer is the center in the width direction H1.

[0021] In this way, the worker can reduce the work of re-inputting the fabrics W by knowing the predetermined position T1 before inputting the fabrics W into the fabric processing device 500. The fabric processing device 500 includes, for example, a fabric input device that spreads out the washed fabrics and a fabric folding device that folds the fabrics into a predetermined shape.

[0022] That is, if the worker does not know the second predetermined position T2 until the fabric W is fed into the fabric processing device 500, the fabric W may be fed out of the second predetermined position T2 in the width direction H of the fabric processing device 500. In that case, the worker must remove the fabric W that was once fed and feed the fabric W again. However, by irradiating the fabric W with light beam R1 at a predetermined position T1 indicating the second predetermined position T2 in the width direction H of the fabric processing device 500 before feeding the fabric W into the fabric processing device 500, the worker can know the second predetermined position T2 from the predetermined position T1 irradiated with light beam R1 before feeding the fabric W into the fabric processing device 500, thereby reducing the work of re-feeding the fabric W.

[0023] In this embodiment, the fabric light projecting device 10 irradiates light beam R1 onto the fabric W to be put into the fabric processing device 500 before the fabric W is put into the fabric processing device 500, and the light beam R1 may be irradiated onto a position indicating the center of the width direction H of the fabric processing device 500, i.e., a predetermined position T1, so as to guide the fabric W to the second predetermined position T2, which is set to the center of the width direction H of the fabric processing device 500.

[0024] In this case, the mark M of the fabric W is also placed at the center in the width direction H1 of the fabric W. Therefore, if the mark M of the unfolded fabric W is placed at the second predetermined position T2, which is the center in the width direction H of the fabric processing device 500, when the fabric W is French-folded in the fabric processing device 500, the mark M can be placed at the center position of the French-folded fabric W1, i.e., the desired predetermined position T3. Therefore, the fabric projector 10 irradiates the fabric W with a light beam R1 indicating the position indicating the center in the width direction H of the fabric processing device 500, i.e., the predetermined position T1, before feeding the fabric W into the fabric processing device 500, so that the fabric W is fed into the fabric processing device 500 so as to coincide with the center position in the width direction H of the fabric processing device 500, i.e., the predetermined position T2. ​​This allows the worker to feed the fabric W into the fabric processing device 500 so that the mark M placed on the fabric W coincides with the predetermined position T2 in the width direction H of the fabric processing device 500. The predetermined position T1 and the predetermined position T2 do not necessarily have to be the center of the width direction H of the fabric processing device 500, and may be any position. Depending on the customer's request, the fabric may be folded so that the mark M is positioned at a position shifted from the center, and the positions of the predetermined position T1 and the second predetermined position T2 can be adjusted by adjusting the positions of the fabric projector 10 and the second light projector 100, respectively.

[0025] The fabric light-projecting device 10 has a light-projecting unit 20, which projects a light ray R1. In this embodiment, the light ray R1 projected by the light-projecting unit 20 is preferably a laser beam. The light ray R1 is preferably a line segment or a dotted line. The length of the line segment is arbitrary, but it is preferable to have a slit (not shown) to limit the range of projection so that the light does not hit the worker, and the projection angle can be set arbitrarily as described later.

[0026] The fabric floodlight device 10 may have an attachment section 30 for attaching the light-projecting section 20. The attachment section 30 can attach the light-projecting section 20 to the fabric processing device 500. The attachment section 30 has an attachment bracket 40 and a beam section 50, and the attachment bracket 40 holds the light-projecting section 20 so as to sandwich it and supports it so that the angle can be adjusted. The attachment bracket 40 is attached to the beam section 50, and the beam section 50 can be attached to the fabric processing device 500. Specifically, the fabric floodlight device 10 of this embodiment is attached to a lower portion 511 of the input conveyor 510 in the fabric processing device 500. In this case, the light-projecting section 20 of the fabric floodlight device 10 can irradiate a light ray R1 onto the back surface of the fabric W. The light ray R1 is irradiated so as to pass through the fabric W, so that the light ray R1 passes through the front surface of the fabric W to be input into the fabric processing device 500, and the worker can visually recognize the transmitted light ray R1. Therefore, by aligning the position of the light ray R1 transmitted through the surface of the fabric W with the position of the mark M, the worker can feed the fabric W into the fabric processing device 500 without misalignment. In this manner, the fabric feeding device 500 may have the fabric light projector 10. The fabric light projector 10 may also be arranged separately from the fabric feeding device 500 (not shown). For example, by separately arranging the fabric light projector 10 below the feeding conveyor 510 in the fabric feeding device 500, the light projector unit 20 can irradiate the light ray R onto the back surface of the fabric W (not shown).

[0027] The fabric processing device 500 may also have a second light projecting unit 100. The second light projecting unit 100 projects a second light beam R2 onto an input conveyor 510 that places fabric W thereon and transports the fabric W toward a folding unit 530 that folds the fabric W, and has an irradiation unit 110 that irradiates light and a second attachment unit 130, and the irradiation unit 110 is attached to the second attachment unit 130. The second attachment unit 130 can be disposed above the fabric processing device 500 and attached to an upper attachment member 150 so as to irradiate light onto the input conveyor 510 in the fabric processing device 500.

[0028] In this embodiment, the light beam R2 emitted by the irradiation unit 110 in the second light projecting unit 100 is preferably a laser beam. The light beam R2 is preferably a line segment or a dotted line. The length of the line segment is arbitrary, but it is preferable to provide a slit (not shown) to limit the irradiation range so that the light does not hit the worker, and the angle of the irradiation unit 110 can also be set arbitrarily.

[0029] The second light projecting unit 100 projects the second light beam R2 onto a second predetermined position T2 in the width direction H on the input conveyor 510 of the fabric processing device 500, and the second light beam R2 is projected onto a position indicating the second predetermined position T2 in the width direction H of the fabric processing device 500. For example, when the second predetermined position T2 is set to the center of the width direction H of the input conveyor 510 of the fabric processing device 500 and the mark M of the fabric W is also positioned at the center of the width direction H1 of the fabric W, by placing the mark M of the unfolded fabric W at the second predetermined position T2 which is the center of the width direction H of the input conveyor 510 of the fabric processing device 500, when the fabric W is French-folded in the fabric processing device 500, the mark M can be positioned at the third predetermined position T3 which is the center of the French-folded fabric W1.

[0030] In this way, the fabric light projecting device 10 can position the fabric W before feeding the fabric W into the fabric processing device 500, and the second light projecting unit 100 can easily place the mark M of the fabric W in an unfolded state at the second predetermined position T2 in the width direction of the feed conveyor 510 in the fabric processing device 500. Therefore, regardless of the level of skill of the worker, the mark M of the fabric W in an unfolded state can be aligned with the second predetermined position T2, which is the center of the width direction H of the feed conveyor 510 in the fabric processing device 500. Note that placing the mark M at the center of the fabric W1 is a customer's request, and as described above, another customer may request a position offset from the center in the width direction H. In that case, the offset positions are set as the predetermined position and the second predetermined position, and the mark M is placed at the positions, so that the fabric W1 can be provided folded with the mark M placed at the third position, which is offset from the center (not shown).

[0031] Next, the process of feeding the fabric W into the fabric processing device 500 and folding it will be described with reference to the fabric projector 10. The predetermined position T1 is a position indicating the center of the width direction H of the feeding conveyor 510 in the fabric processing device 500, the second predetermined position T2 is the center of the width direction H of the feeding conveyor 510 in the fabric processing device 500, and the third predetermined position T3 is a position in which the mark M of the folded fabric W1 is positioned at the center of the width direction H1 of the fabric W.

[0032] A light beam R1 is projected by the light projecting device 10 onto a position indicating a predetermined position T1 on the fabric W to be fed into the fabric processing device 500. An operator (not shown) prepares to feed the fabric W by positioning a mark M on the fabric W at the predetermined position T1 (see FIG. 8A).

[0033] Next, an operator (not shown) places the fabric W on the input conveyor 510 of the fabric processing apparatus 500 while aligning the mark M with the predetermined position T1 (see FIG. 8B). In this case, the second light projecting unit 100 arranged in the fabric processing apparatus 500 irradiates the second light beam R2 to the second predetermined position T2 on the input conveyor 510 of the fabric processing apparatus 500, and in this case, the second light beam R2 is irradiated to the center in the width direction H. Therefore, the position of the light beam R1 in the width direction H coincides with the position indicating the predetermined position T1 and the position of the light beam R2 in the width direction H, so that the operator (not shown) can place the fabric W on the input conveyor 510 without misalignment.

[0034] Next, the fabric W placed on the input conveyor 510 is transported to a folding section 530 having a right knife 530a and a left knife 530b for French folding (see FIG. 9A). The right side of the fabric W transported to the folding section 530 is folded by the right knife 530a (see FIG. 9B), and the left side of the fabric W is folded by the left knife 530b (see FIG. 10A).

[0035] The fabric W is French-folded by the folding unit 530, and the folded fabric W1 is discharged (see FIG. 10B). At this time, the mark M is placed at the third predetermined position T3 of the folded fabric W1. In this manner, the fabric projector 10 can prepare the fabric W so that the mark M is placed at the predetermined position T1 even by an operator who is not accustomed to feeding fabric W. In addition, the fabric processing device 500 further includes the second projector 100, and therefore can discharge the folded fabric W1 while placing the mark M at the position desired by the customer.
