Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to, for example, accommodation facilities,
The present invention relates to a folding device that folds towels widely used in hospitals, nursing homes and the like, and cloth products such as towels provided in restaurants and vehicles, etc., in a four-fold state.

[0002]

2. Description of the Related Art For example, towels used in an accommodation facility will be described. Towels used in an accommodation facility are shipped together to a laundry company, and the laundry company delivers clean and dry towels to the accommodation facility again. I'm doing In this case, if the towels are delivered in a spread state, it is inconvenient to transport the towels, and a large amount of towels must be folded at the accommodation facility, and the labor becomes remarkable.
Therefore, after washing and drying in the laundry, the towels are further folded and delivered to the accommodation facility. In some cases, folded towels are packed in bags and delivered.

[0003] Usually, cloth products or the like that are long in the horizontal direction, such as towels, are delivered in a so-called four-folded state by folding a half-folded product and then half-length. For this reason, it is common for a laundry trader to wash and dry, and then fold a cloth product or the like into a four-fold state using a dedicated folding device. 2. Description of the Related Art Conventionally known folding devices place a cloth product or the like on a conveyor arranged on a horizontal surface and convey the cloth product, and when the front end of the cloth product or the like hangs down from the end of the conveyor, pushes the cloth product or the like laterally with a blade. Thereby, the cloth product or the like is folded.

[0004]

In order to fold a cloth product such as a towel into four folds, it is necessary to measure the entire length of the cloth product. For example, bath towels and small towels have different lengths, but measure the length of various cloth products, etc., which differ in length in this way, and use the blade to accurately determine the half or quarter position of the cloth products, etc. If it is not pushed in, it is impossible to fold it neatly in four.

Therefore, conventionally, a front end and a rear end of a cloth product are detected by a sensor while the cloth product or the like is placed on a conveyor and conveyed, and the detection timing, the conveying speed of the conveyor, and the front and rear ends of the cloth product are detected. The length of a cloth product or the like is calculated based on the position of each sensor that has detected the end. Then, based on the length of the cloth product or the like calculated in this manner, the blade is advanced at an appropriate timing in a state where the cloth product or the like hangs down from the end of the conveyor, so that a half position of the cloth product or the like can be obtained. The quarter position is pushed in with a blade and folded into a four-fold state.

However, since the conventional folding device measures the length while the cloth product or the like is spread on the conveyor, a long conveyor is required, and the entire folding device is considerably large. For this reason, a large installation space was required.

Further, the conventional folding device has no means for correcting the posture of the cloth product or the like, and when the cloth product or the like is placed on the conveyor in an inclined state, the cloth product is folded as it is and the cleanness is improved. Could not be folded in four. For this reason, when placing a cloth product or the like on the conveyor, it is necessary to align the front end of the cloth product or the like so as to be exactly perpendicular to the traveling direction of the conveyor.

Further, in the conventional folding device, when a cloth product or the like is placed on a conveyor in a wrinkled state, the wrinkles cannot be stretched, and the end portion may be folded in a bent state. was there. For this reason, it is necessary to stretch the wrinkles of the cloth products and the like and put them on the conveyor,
The work was complicated.

Accordingly, an object of the present invention is to reduce the installation space, and to easily correct the posture of a cloth product or the like and to straighten wrinkles of the cloth product, so that the cloth product can be folded neatly into four. It is to provide a folding device.

[0010]

In order to solve the above-mentioned problems, the present invention is directed to a folding apparatus for folding a cloth product or the like supplied in a spread state into a four-fold state. A pair of left and right rollers arranged in series in the horizontal direction to be applied, and a sensor mechanism for detecting the length and inclination of a cloth product applied over the left and right rollers;
By rotating the left and right rollers appropriately, a rotation drive mechanism capable of adjusting the number of rotations to make the cloth product or the like stretched over the left and right rollers into an unfolded two-fold state, It is characterized in that it is provided with a pressing mechanism that pushes out a cloth product or the like that has been applied to the left and right rollers in the folded state to the side to make it into a four-fold state.

When the cloth product is folded in four by the folding device according to the first aspect, the cloth product or the like is first straddled by both the pair of left and right rollers arranged in series in the horizontal direction. multiply. In this case, the cloth product or the like applied to the roller may have some inclination.

Next, the length and inclination of the cloth or the like applied to the roller by the sensor mechanism are detected. Preferably, the sensor mechanism includes a front end detection sensor for detecting a front end of a cloth product or the like and a rear end detection sensor for detecting a rear end of the cloth product.
Then, the front end and the rear end of the cloth and the like are detected by the front end detection sensor and the rear end detection sensor, respectively, while the cloth and the like applied to the rollers by the operation of the rotation drive mechanism are appropriately moved. The length of the cloth product or the like can be calculated based on the detection timing of the rear end, the peripheral speed of the rollers, and the positions of the front end detection sensor and the rear end detection sensor that detect the front end and the rear end. Note that it is not always necessary to separately provide the front end detection sensor and the rear end detection sensor. One sensor detects both the front end and the rear end of a cloth product or the like, so that the front end detection sensor and the rear end detection sensor can be used. You may do it.

It is preferable that at least one of the front end detection sensor and the rear end detection sensor constituting the sensor mechanism is constituted by a pair of left and right sensors arranged at the same height. Then, while appropriately moving the cloth or the like applied to the roller by the operation of the rotary drive mechanism, the timing of detecting the front end or the rear end of the cloth or the like detected by the pair of left and right sensors, the peripheral speed of the roller, and the like. The inclination of the cloth product or the like can be calculated based on the interval between the pair of left and right sensors.

Next, the right and left rollers are driven to rotate at appropriate peripheral speeds while adjusting the number of rotations of the rotary drive mechanism, so that the moving speed of the cloth product or the like straddling the right and left rollers is required. The left and right are made different accordingly, and the cloth product etc. is made to be in a state without inclination. Then, as described in the third aspect, the cloth product or the like applied over the left and right rollers in this manner is in a state without inclination, and the front end and the rear end of the cloth product or the like applied on the roller have the same height. When the sheet is folded in half, the rotation of the rotation drive mechanism is stopped.
As a result, the cloth product or the like has no inclination, and is folded in half at the center so that the front end and the rear end are at the same height, and are placed on the left and right rollers of the folding device.

Next, the cloth product or the like which has been folded in two without inclination is pushed out to the side by a pressing mechanism to be folded in four. The pressing mechanism may be a blade that is horizontally arranged so as to push the cloth product or the like laterally at a substantially central height of the folded cloth product or the like. Can be. Further, when the cloth product or the like is pushed to the side by the pressing mechanism, as described in claim 5,
It is preferable that the left and right rollers descend relatively in conjunction with the pushing mechanism pushing out the cloth product or the like, and further, the left and right rollers move away from each other. This eliminates the risk of the fabric product being pulled by the left and right rollers when pushing the fabric product, etc., to the side by the pressing mechanism, and always presses almost the height of the center of the folded fabric product etc. By pushing out to the side by the mechanism, it becomes possible to fold the cloth product etc. neatly into four folds.

The cloth product or the like folded in four in this manner may be configured to be carried out by a carry-out mechanism or the like, for example, as described in claim 6.
In this case, for example, a belt conveyor or the like can be used as the unloading mechanism. In that case, the four-fold folded cloth products etc. are delivered on the belt conveyor,
It is sufficient for the belt conveyor to have a quarter length of a cloth product or the like.

It is much wider than that. Although FIG. 1 illustrates the case where the motors 7 and 8 are moved in a state where the guide moving mechanisms 5 and 6 are moved up by the operation of the guide elevating mechanisms 3 and 4, the operation of the guide elevating mechanisms 3 and 4 is described. Similarly, in the state where the guide moving mechanisms 5 and 6 are lowered (the state shown by the two-dot chain lines 7 'and 8' in FIGS. 1 and 2), the guide moving mechanisms 5 and 6 are similarly moved.
The motors 7 and 8 are moved by the operation of
It is configured so that the members 1 and 12 can be separated from each other.

In front of the folding device 1 (left side in FIG. 2), a blade 15 as a pressing mechanism is horizontally arranged. The blade 15 is supported on the upper surface of the slide mechanism 16, and as described later, the slide mechanism 16
By moving the blade 15 to the rear side (right side in FIG. 2) by the operation of the towel, the towel A applied to the rollers 11, 12 is pushed out to the rear side, and the towel A is folded into four. It is configured. In order to cleanly fold the towel A into four folds, the towel A applied to the rollers 11 and 12 by the blade 15 is used.
Since it is necessary to extrude the height of the center (a quarter of the height), the height of the blade 15 can be changed so as to be compatible with various towels A having different lengths. good.

The operation of the left and right guide lifting mechanisms 3 and 4 and the operation of the left and right guide moving mechanisms 5 and 6 are linked to the operation of the slide mechanism 16 that moves the blade 15 as described above. Is controlled as follows. That is, when the movement of the blade 15 to the rear side is started by the operation of the slide mechanism 16, the guide elevating mechanisms 3, 4 are operated accordingly, and the guide moving mechanisms 5, 6 maintain the same height. While descending at the same time.

A front end detection sensor 30 for detecting a front end A 'of the towel A is disposed in front of (to the left in FIG. 2) the towel A applied to the rollers 11, 12.
A rear end detection sensor 31 for detecting the rear end A ″ of the towel A is disposed behind (to the right in FIG. 2) the towel A. In the illustrated example, the front end detection sensors 30 have the same height. The rear end detection sensor 31 is also formed of a pair of left and right sensors S3 and S4 similarly arranged at the same height as each other. One of the front end detection sensor 30 (sensors S1 and S2) and the rear end detection sensor 31 (sensors S3 and S4)
The length and the inclination of the towel A spread over the areas 1 and 12 are detected.

Behind the folding device 1 (to the right in FIG. 2), a belt conveyor 20 as a carry-out mechanism is horizontally arranged. The belt conveyor 20 is configured to revolve clockwise in FIG. 2 by winding an endless belt 23 around a pair of conveyor rollers 21 and 22. Further, below the rear end of the belt conveyor 20 (below the right end in FIG. 2), a container 25 for storing the towel A folded in four is arranged. Then, the towel A folded in four while being pushed rearward by the blade 15 is conveyed rightward in FIG. 2 by the belt conveyor 20 and dropped into the container 25 below the rear end of the belt conveyor 20. It is designed to be stored. It is preferable that the height of the belt conveyor 20 can be changed according to the change of the height of the blade 15 described above.

When the towel A is folded in four by the folding apparatus 1 constructed as described above, the guide moving mechanisms 5, 6 are raised by operating the guide elevating mechanisms 3, 4 in advance, and the guide moving mechanism is moved. By operating the motors 5 and 6, the motors 7 and 8 are moved closer to each other. Then, as shown in FIG.
Spread the towel A in a state where it spreads so as to straddle both 1 and 12. In this case, the towel A applied to the rollers 11 and 12 may have a slight inclination θ.

Next, the front end detection sensor 30 (sensor S1,
S2) and the rear end detection sensor 31 (sensors S3, S4) detect the length X and the inclination θ of the towel A spread over the left and right rollers 11, 12. Here, the length X of the towel A is determined by the operation of the left and right motors 7 and 8.
While appropriately moving the towel A hung on 1, 12
The front end A 'of the towel A is detected by the front end detection sensor 30 (sensors S1, S2) and the rear end detection sensor 31 (sensors S3, S4).
And the rear end A ″, respectively, so that the detection timing T ′ of the front end A ′ and the detection timing T ″ of the rear end A ″ and the peripheral speed V of the rollers 11 and 12 (the radius of the rollers 11 and 12 are R , If the rotation speed is ω, V = R × ω) and the front end detection sensor 30 (sensors S1, S2) and the rear end detection sensor 31 (sensors S3, S4) for detecting the front end A ′ and the rear end A ″. Can be calculated based on the position of the towel A. That is, as shown in FIG. 4, the distance between the front end detection sensor 30 (sensors S1 and S2) and the rollers 11 and 12 is L1, and the rear end detection sensor 31 (sensors S3 and S4) and the roller 1
If the distance between L1 and L12 is L2, the length X of the towel A can be calculated by the following equation (1).

X = L 1 + L 2 + V × (T ″ −T ′) Expression 1

The detection timing T 'of the front end A' is
The front end A 'of the towel A is detected by the sensor S1 of the front end detection sensor 30.
The average value of the time when the front end A 'of the towel A was detected by the sensor S2 and the time when the front end A' of the towel A was detected was used as the detection end T "of the rear end A". It is preferable to use the average value of the time when A "is detected and the time when the rear end A" of the towel A is detected by the sensor S4.

The inclination θ of the towel A can be determined by detecting the front end A ′ of the towel A by a pair of left and right sensors S 1 and S 2 disposed at the same height and constituting the front end detection sensor 30, respectively. The rear end A "of the towel A is detected by a pair of left and right sensors S3 and S4 arranged at the same height, which constitute the end detection sensor 31, and the front end A 'of the towel A is detected by the sensors S1 and S2. Time T
1 ', T2', or any of the detection times T1 ", T2" of the rear end A "of the towel A by the sensors S3, S4, the peripheral speed V of the rollers 11, 12, and the distance between the sensors S1, S2, or The inclination θ of the towel A can be calculated based on the distance between the sensors S3 and S4, that is, for example, as shown in FIG.
In the case where the inclination θ of the towel A is calculated by taking the case where the front end A ′ of the towel A is inclined to the lower left as shown in FIG. When the sensor S1 moves to the position indicated by the solid line,
As a result, the front end A ′ of the towel A is detected. Assume that the time (detection time) at this time is T1 '. Next, the towel A moves with the rotation of the rollers 11 and 12, and the front end A 'of the towel A is detected by the sensor S2 when the towel A moves to the position indicated by the solid line in FIG. . Assume that the time (detection time) at this time is T2 '. The moving distance Y of the towel A during this time is
It is expressed by the following equation 2 using the peripheral velocity V of 2.

Y = V × (T 2 ′ −T 1 ′) Expression 2

Therefore, assuming that the distance between the sensors S1 and S2 is D, the inclination θ of the towel A can be expressed by the following equation (3).

Θ = tan ⁻¹ (Y / D) = tan ⁻¹ (V × (T 2 ′ −T 1 ′) / D) Equation 3

Although the case where the inclination θ of the towel A is calculated by using the sensors S1 and S2 constituting the front end detection sensor 30 has been described, the left and right sensors S3 and S3 constituting the rear end detection sensor 31 have been described. S4, rear end A of towel A "
, The inclination θ of the towel A can be calculated by the same procedure. Also, the case where the front end A 'of the towel A is inclined downward and to the left has been described as an example, but when the front end A' of the towel A is inclined downward and to the right, the inclination θ of the towel A is a negative value. Is calculated.

Next, as described above, the length X of the towel A
And the inclination θ, and then the calculated length X and the inclination θ
The rotational speeds of the left and right motors 7 and 8 are adjusted based on the values of the right and left rollers 11 and 12 to rotate at appropriate peripheral speeds, respectively.
The moving speed of the towel A applied over the rollers 11 and 12 is made different between the left and right by relatively changing the peripheral speed of the left and right in the left and right. Thus, the left and right rollers 11,
When the towel A applied over the roller 12 is not tilted and the front end A ′ and the rear end A ″ of the towel A applied on the rollers 11 and 12 are folded in the same height. Then, the rotation of the motors 7 and 8 is stopped, so that the towel A is folded at the center so that the front end A 'and the rear end A "have the same height as shown in FIG. Rollers 11 and 12 of the folding device 1
It is in a state of being subjected to.

Next, after the towel A is folded in two without inclination as described above, the blade 15 is moved to the rear side (rightward in FIG. 7) by the operation of the slide mechanism 16 as shown in FIG. ), The roller 1
The height (a quarter of the height) of the center of the towel A applied to the towels 1 and 12 is pushed to the rear side by the tip of the blade 15, and the towel A is neatly folded in four. As described above, when the blade 15 slides and the towel A is folded in four in this manner, the guide elevating mechanisms 3 and 4 operate accordingly, and the guide moving mechanisms 5 and 6 mutually move. At the same time, the rollers 11 and 12 also descend while maintaining the same height. Therefore, there is no fear that the towel A is pulled upward by the rollers 11 and 12, and the height of almost the center of the folded towel A can always be pushed out by the tip of the blade 15, so that the towel A is clean. Can be folded into four folds.

After being pushed out by the blade 15 in this manner, the towel A folded in four is placed on the upper surface of the belt conveyor 20 arranged behind the folding device 1, and then the guide moving mechanisms 5, 6 are operated. hand,
As shown in FIG. 8, the motors 7, 8 move in opposite directions so as to be separated from each other, and the rollers 11, 12 are separated from each other to the left and right. Thereby, the inner surface 1 of the rollers 11 and 12
The rollers 11, 12 move to a position where the interval between 1a, 11b is sufficiently larger than the width L of the towel A, and the towel A
, And the towel A folded in four is delivered to the upper surface of the belt conveyor 20.

Next, as shown in FIG.
6, the blade 15 is moved to the front side (left side in FIG. 9), and the blade 15 is extracted from between the towels A. The towel A transferred to the upper surface of the belt conveyor 20 is transported to the rear of the folding device 1 (to the right in FIG. 9) by the operation of the belt conveyor 20 in a state where the towel A is folded in four. Then, as shown in FIG. 10, the towel A falls from the end of the belt conveyor 20 (the right end in FIG. 9), and thus, as shown in FIG. Is stored inside. Thus, by repeating the same steps, the towels A that have been neatly folded into four are sequentially stored in the container 25. Since the towel A folded in fourfolds is always delivered on the belt conveyor 20 as described above, the length of the belt conveyor 20 needs to be a quarter of the length of the towel A. It is.

According to the folding device 1 described above,
The towel A can be easily spread by applying the towel A to the left and right rollers 11 and 12, and the front end A 'and the rear end A "of the towel A can be naturally lowered by their own weight by applying the rollers 11 and 12. There is no fear that the towel A will be bent because the towel A is bent, and by appropriately adjusting the rotation speed of the left and right rollers 11, 12, the towel A is not tilted, and the front end A 'and the rear end A "
Can be folded in the center so that the towels are at the same height. In this way, by pushing the height of almost the center of the towel A folded in a correct position with the tip of the blade 15, the towel A Has the characteristic that it can be folded neatly into four folds.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be appropriately modified and implemented. For example, as shown in FIG. 11, a holding belt 30 may be arranged above the belt conveyor 20 in parallel with an appropriate interval. In this case, the towel A folded in four can be pressed from above while being transported, and there is no fear that the folded posture collapses. Further, as shown in FIG.
May be configured to be pulled out to both sides of the towel A by rotating the towel to the left and right.
