Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a linen delivery device used in a device for sorting laundry or textile products, a device for spreading pieces of cloth, and the like.

(Prior Art) A device for automatically sorting or unfolding laundry for linen supplies (hereinafter referred to as linen) has not conventionally existed, and has relied solely on human labor. Conventionally, hotels,
Used and dirty linen received from customers such as hospitals,
When linen is delivered to a processing factory, various items are mixed in bags and containers.

Therefore, workers had to manually sort each type of linen and put the same type of linen together into a tunnel washing machine.

At the laundry factory, the incoming linen (especially sheets) is washed in a tunnel washer, etc., then dehydrated, placed in a dryer for pre-drying, then loosened, unfolded, ironed, folded, and shipped. do. In order to iron these pre-dried sheets, 5 to 6 workers take out sheets one by one from the mass of sheets discharged from the dryer, unfold them, and feed them into the ironing machine. but,
Sorting is also done manually, just like with the equipment. Currently, there is no linen sorting device or linen unfolding device that can automatically perform such operations, and therefore, there is also no linen delivery device that plays an important role in these devices.

(Problems to be solved by the invention) As mentioned above, conventional linen sorting was done manually, which was not only hard labor but also unfavorable from a sanitary standpoint, and it was difficult to control the amount of goods received. There was a problem. Furthermore, conventional ironing work for unfolding washed sheets and the like has been done manually near the machine, which has had the problem of forcing the work to be carried out under adverse conditions such as high temperature and humidity.

The present invention solves the above-mentioned conventional problems and can automatically sort linen without human intervention, reduce labor, be sanitary, and iron washed sheets. Therefore, it is an object of the present invention to provide a linen delivery device which is an important means for unfolding pieces of cloth in order to automatically unfold sheets.

(Means for Solving the Problems) Therefore, the present invention has a means for receiving a chuck for transporting linen, a means for opening the received chuck so as to be able to grip linen, and a means for automatically opening the chuck in response to a linen gripping signal. This device consists of a means that moves closed to grip the linen and send it out into the chuck conveyance rail, and this is a means for solving the problem.

(Operation) The linen taken out one by one from the belt conveyor by the linen gripping section is reliably delivered to the chuck by the linen delivery means.

The empty chuck after gripping the linen and carrying out a predetermined conveyance is supplied to each linen delivery means by the rail. The chuck, which is then fed into the chuck positioning rail, is opened by a chuck opener to grip the linen. After the linen is gripped by the chuck, the linen gripping part releases the gripping of the linen, and the linen is transferred from the linen gripping part to the chuck.Then, the chuck is discharged into the linen gripping chuck conveying rail, It is transported to the next process by a transport chain.

On the flat part, the installation angle of the rail 43 is inclined by about 5 degrees so that the chuck 7 moves under its own weight. put. 44 is a merging device. In order to improve the linen sorting capacity, it is necessary to install a plurality of linen take-out means 2 and linen delivery means 3 as shown in FIG. In this case, so that the chucks 7 conveyed from each into the rails do not interfere with each other,
This merging device 44 is necessary.

The principle of this device is the same as point switching on railway rails.

45a to 45d are chuck openers, and after the type of linen is determined, the chuck 7 that grips the linen 8 is stopped at a predetermined chuck opener position according to the type of linen by a stopper (not shown), and the book is opened using an air cylinder or the like. The grip on the chuck 7 is released by the device. 46 is a distribution device, and when a plurality of linen delivery means 3 are installed, it is necessary to equally supply empty chucks 7 to each of them. Note that the principle is the same as that of the merging device 44.

Next, the linen sorting information detection means 5 will be explained. 51 is a linen hanging length detector, and a plurality of photoelectric sensors or limit switches are installed near the rail 43.
Touch sensors and the like are vertically arranged to detect the length of a single piece of linen 8 that is hung. 5
Reference numeral 2 denotes a weight measuring device which is capable of measuring the weight of a single piece of linen 8 that has been transported, and is of a load cell type or a spring type.

A color detector 53 is a color sensor formed to optically detect the color of a single piece of linen 8. Reference numeral 54 denotes a metal detector, which detects a metal recognition piece sewn onto the linen 8 when it is difficult to identify the hanging length and weight of the linen 8 using only information such as electromagnetic induction using high frequency. It uses the action. The metal recognition piece has a size, shape, material, etc. depending on the type of linen 8, and is set in advance so that induced currents of different sizes flow through it due to electromagnetic induction. 55 is a guide plate, and when the linen 8 is guided into the metal detector 54, if the linen 8 comes into contact with the metal detector 54, noise may be generated and detection may become difficult. On the other hand, the magnitude of the detection signal may differ slightly in the detection area of the metal detector. For this reason, the plate is provided in the detection area with a guide made of resin or the like that does not affect the magnetic field to prevent the above-mentioned problems from occurring.

Reference numeral 57 denotes a control device which, when supplied with information detected by the detectors and measuring devices 51 to 54, stores this information in a data memory and performs processing such as comparison and judgment.
The product type is determined and sorting instructions are sent. That is, this control device 57 is mainly configured with a central control device 61, and each device 62 to 65 is connected to this central control device 61. Reference numeral 62 denotes a sensor data storage device that stores information from the hanging length detector 51 to metal detector 54, that is, sensor data when it is provided via the central control device 61. 63 is a type discrimination device, and a central control device 6
This device compares the data stored in the sensor data storage device 62 provided via the sensor data storage device 62 with standard data set by the sorting standard setting device 64 to determine the type of each linen.

Reference numeral 64 denotes a sorting standard setting device, which is a device that sets standard data for determining linen types in advance.

Reference numeral 65 denotes a display device that displays data such as the number of sheets by type and the total number of sheets sorted based on the data from the devices 62 and 63. The control device 57 is provided with a command device (not shown) for sorting, and as shown by the arrow, a command signal S is sent out for sorting according to the determined linen type.
Each linen 8 that has reached the linen 8 release portion of the rail 43 is automatically sorted by the chuck opener 43.

Next, the operation will be explained. As shown in FIG. 1, the linen 8 that has arrived is placed on the supply conveyor 11.

Thereafter, the linen 8 is sent to the linen supply means 1, where the linen 8 is lifted upward by the inclined conveyor 12, and as it falls onto the horizontal conveyor 13, the linen 8 is subjected to the effect of being loosened one by one.

Next, the horizontal conveyor 1 is supplied via the horizontal conveyor 13.
The linen 8 on the top 4 is picked up one by one by the linen take-out means 2. That is, the linen gripping part 21 is lowered via the arm 22 by the arm lifting mechanism 24,
Grip the linen 8 on the horizontal conveyor 14. At this time, the presence of the linen 8 is recognized by a photoelectric sensor (not shown) attached to the linen gripping part 21, and when the presence of the linen 8 is detected, the descending speed is slowed down and the linen gripping part 2 is placed inside the linen 8.
1 is controlled so that it does not slip in.

Thereafter, by suctioning means (not shown) from the opening of the linen gripping part 21, one sheet of linen 8 is suctioned and lifted by several millimeters to several tens of millimeters. Subsequently, the lifted linen 8 is securely gripped by a gripper (not shown) built in the linen gripper 21. When the linen gripping part 21 rises by gripping the linen 8, if a force exceeding a certain load is applied, the sensor 25 detects this and releases the grip. This occurs when the linen 8 is not loosened sufficiently, and is intended to prevent damage to the linen 8 caused by lifting it upward. Therefore, when normally supplying linen 8 to linen supply means 1,
It is desirable that the linen 8 comrades have already been loosened sufficiently.

Further, the linen 8 taken out one by one from the belt conveyor by the linen gripping section 21 is transferred to the linen delivery means 3.
This ensures that it is delivered to the chuck 7. Then grab linen 8.

The empty chuck 7 after being transported for a certain period of time is placed on the rail 4.
3 to each linen delivery means 3. Further, a chuck supply device shown in FIG. 4 is attached to the empty chuck supply rail 311.

That is, first, the supplied empty chuck 7 is transferred to the air cylinder 3.
12 is operated and the rod 313 is extended, the cam 314 is positioned as shown by the solid line in FIG. Next, the air cylinder 312
3 into the cylinder, the cam 314 is moved as indicated by the two-dot chain line in FIG. As a result, the lowest end of the chamfer 7 that was in contact with the cam 314 is now 1
Only the pieces are fed downward by their own weight.

Furthermore, the chuck 7 fed into the chuck positioning rule 32 is moved by the chuck opener 34 as shown in FIG. 3 (a).
It is opened so that the linen 8 can be grasped as shown in position (A). That is, the chuck 7 is attached to the arm 7 as shown in FIG. 5(a).
By pushing 1 in the direction of the arrow, it can be opened as shown by the two-dot chain line. After this, the indexing table 33 with the chuck positioning rail 32 attached thereto is moved by the indexing device 38 as shown in FIG. 3(a).
It is rotated as shown by arrow A. At this time, the linen gripping section 21 rises while gripping the linen 8, and the linen gripping section 21 rises as shown in FIG.
) is waiting at the position. Of course, the linen grip part 21
1. is located at a position that does not interfere with the indexing table 33. The linen 8 is gripped by the rotating chuck 7.

After the linen 8 is gripped by the chuck 7, the linen gripping part 2
1 releases the grip on the linen 8, and now the linen grip part 21
The linen 8 is transferred from the chuck 7 to the chuck 7 (Fig. 3 (a)
l position (B)). Also, the chuck 7 holding the linen 8
is rotated as it is by the indexing table 33, and reaches the position (C) from the position (B) in FIG. 3(a). At this time, since the plate 35 still exists under the chuck 7, the chuck 7 is placed at the position of the periphery (C).

Here, the air cylinder 36 fixed to the indexing table 33 is operated by compressed air sent from the rotary head 37, and the plate 35 is brought into the state shown in (C) of FIG. 3 ia1. As a result, the chuck 7 is discharged into the linen gripping chuck discharge rail 39, and is conveyed to the next process by the conveyance chain 41. On the other hand, after confirming that the plate 35 has moved in this way, one empty chuck 7 is supplied into the chuck positioning rail 32, which is in the state shown in FIG. 3(a) and (A). , one process of the linen delivery device 3 is completed.

Next, the operation sequence of the linen delivery means 3 described above will be explained in more detail based on FIG. 6. Here, (A) and (C) are used as the receiving and discharging positions of the chuck 7.
The case of two positions will be explained.

1. Now position (A) chuck positioning rail 3
There is a plate 35 at the bottom of the chuck positioning rail 32 at position (C), but there is no plate 35 at the bottom of the chuck positioning rail 32 at position (C) (that is, the plate 35 is at the bottom of position (A),
(C) Controlling the movement of the chuck 7 in either position).

(2) First, the chuck 7 is supplied to position (A).

(9) Next, the chuck opener 34 in position (A) operates to open the chuck 7. At this time, the linen gripping part 2
1 holds the linen 8 and waits at a predetermined position.

■6 An indexing device (not shown) rotates clockwise. At this time, the chuck 7 remains opened by the chuck opener 34.

(2) The linen gripping section 21 grips the linen 8 and is on standby at a position where the indexing device has been rotated approximately 90 degrees. Accordingly, the chuck opener 34 closes at a predetermined position, the chuck 7 grips the linen 8, and the linen gripping section 21 releases the grip on the linen 8 that it had previously gripped. After this, the indexing device continues to rotate.

■, and the indexing device is initially 1. It rotates 180° as seen from the position and stops. (At this time, position (A)
) will replace the position of (C) in the initial ■.).

In this state, the plate 35 covers position (A). Next, operate the air cylinder 36 to move the plate 35 to the 1. Change it like this. At this time, the chuck 7 in the (C) position at
The linen gripping chuck 7 is fed into the discharging rail 39 while still being gripped. As described above, one process of linen delivery is completed.

Next, the chuck 7 holding the linen 8 is lifted upward by the conveying chain 41.

This is because some of the linen targeted by this device has a hanging length of 3.0 m or more, and the linen delivery means 3 is usually located at a lower position than this. This is because it is necessary to lift it up. Of course, it is also possible to create an apparatus that does not require the conveyance chain 41 by digging down this part or by installing the linen delivery means 3 on the mezzanine floor or the like. The chuck 7 holding the linen 8 is transported by a transport chain 41.

Next, the chuck 7 holding the linen 8 is sent to the information detecting means 5 for sorting the linen. Here, the hanging length of the single linen 8 suspended from the chuck 7 is always within a certain length range.

For example, if the taken out single linen 8 is a rectangular cloth as shown in Figure 9fa), its maximum length is the diagonal length C when gripping point A as shown in Figure 9(b), and the shortest length is C. The length is the 9th
The half-diagonal length is 1/2N when gripping the 0 point, which is the center point, as shown in Figure (C1).Also, even in the case of irregularly shaped linen like a yukata, the hanging length is certain. It is within a specific length range.If it is necessary to detect the hanging length with more precision, as shown in FIGS. 8,
By grasping it again, it is possible to easily grasp the end portion that has the maximum hanging length.

That is, when a single piece of linen 8 made of rectangular cloth is first gripped by the first chuck 7A as shown in FIG. 10 ta+,
Assume that an arbitrary point P is grasped as shown in fb) in the same figure. At this time, the lowest point of the suspended linen 8 is point A at one corner of the rectangular cloth. Therefore, the second chuck 7B is used as shown in the figure (
As shown in C1, grasp the lowest point, that is, point A again. By doing this, the single linen 8 is hung at its maximum hanging length.

In this way, the hanging length of the linen 8 suspended within a certain range is detected by the hanging length detector 51, and the detected information is transmitted to the control device. 57. When the single piece of linen 8 is conveyed to the weighing device 52, its weight is measured there. The weight varies depending on the moisture content of the linen 8. In other words, linen 8 usually arrives in a dry state, but
Some items received from customers such as hotels are slightly damp. The water content in sheets, yukata, pillowcases, etc. is small, but towels can contain up to twice the weight of linen.

However, since there is usually a significant difference in the basic weight of a single linen 8 based on its type, discrimination is possible. In order to detect the weight more accurately, it is desirable to dry the linen using some kind of drying means before measuring the weight to keep the moisture content constant. This moisture content can also be added to the weight information for correction. The measured weight information is transmitted to the control device 57.

Furthermore, when the single linen 8 is conveyed to the color detector 53, it is detected here which of the four color systems white, yellow, red, and blue it belongs to, and this information is sent to the control device 57. transmitted. Furthermore, when the single linen 8 is conveyed to the position of the metal detector 54, information such as whether a metal recognition piece is sewn on the single linen 8 and its size is detected. It is transmitted to the control device 57. Therefore, if the single linen 8 is, for example, "patterned" and it is difficult to distinguish the color,
Accurate information can be obtained especially in cases where sorting is required for items of the same type.

Each piece of information transmitted to the control device 57 is stored in the sensor data storage device 62, and when all or part of the stored data is sorted, it is compared with standard data set by the standard setting device 64 in the product type discrimination device 63. be judged. As a result, the type of the single linen 8 is determined and classification is performed.

Note that in the control device 57, the number of sheets of the same type of linen 8 is counted and displayed on the display device 65, so that the arrival management can be performed appropriately. In linen sorting, when the type of linen 8 is determined by the information detecting means 5, the chuck 7 holding the linen 8 is carried within the rail 43 to the positions of the chuck openers 45a to 45d.

For explanation purposes, chuck openers 453 to 45 are shown here.
There are four positions (d), but as many positions as necessary for sorting linen 8 can be installed.

Next, depending on the type of linen 8, the chuck 7 gripping the linen at each position of the predetermined chuck openers 45a to 45d is stopped by a stopper (not shown), and the chuck 7 is opened by the chuck openers 45a to 45d operated by an air cylinder or the like. The grip is released, and the linen 8 is stored in the linen stock trolley 6, waiting thereunder. Linen 8 of a predetermined type is fed into the trolley 6 in a fixed weight or in a fixed number, and the trolley 6 is automatically or manually replaced with another empty trolley. Furthermore, the chuck that has released the linen 8 held by the chuck opener 45 moves within the rail 43 under its own weight, and is controlled by the distribution device 46 so that a fixed amount is supplied to each linen delivery means 3. Ru. In this way, the chuck 7 is used while being circulated within the apparatus.
