Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linen supply turn which can easily supply washed laundry (linen) such as sheets in a semi-dry state to a linen developing conveyor for ironing in the next step in a laundry factory or the like. The present invention relates to a table device.

2. Description of the Related Art Generally, in a laundry factory, incoming rectangular sheets such as sheets and wrapping cloths are washed with a continuous washing machine and then dried with a dehydrator and then dried with a dryer. The rectangular cloth after being crushed is taken out from the dryer while being rolled into a nodule. By the way, the rectangular fabrics that have undergone the drying process are conveyed to a certain place by a belt conveyor and piled up there.When the rectangular fabrics are sent to an ironing device or a spreader feeder which is an auxiliary device thereof, etc. Is
It is effective to develop these cloths in advance in order to improve the processing capacity. In this unfolding work, first, one worker manually finds one corner of the rectangular cloth, and then unfolds the other corner along one edge from the corner. I was letting it. However, the rectangular cloth that has undergone the drying process is in a state of being rolled into a nodule shape as described above, and in order to manually find one corner portion from such a nodule-shaped rectangular cloth, This nodular rectangular cloth has to be unraveled or turned upside down to find it, and the work of finding its corners is a troublesome and extremely time-consuming operation. Also, after finding one corner, when searching for another corner adjacent to it,
The rectangular cloth had to be unraveled, and the work of expanding the edges was extremely troublesome.

As a solution to the troublesome work of manually unraveling this nodule-shaped rectangular cloth and searching for one corner, equipment for simplifying the unraveling work having the following structure is provided to the market. ing. That is, as a cloth conveying method for a spreader feeder, only one corner of a rectangular cloth is taken out, two neighboring edges are grasped by a feeder conveyor clamp, and the feeder conveyor conveys the cloth to a spreading device. Is to be developed. An example of such a configuration is shown in FIGS. In FIG. 5 and FIG. 6, the washed and dehydrated cloths 7 are loaded into the dryer 1 by the conveyor 9, dried in the dryer 1, transported by the belt conveyor 2 and piled up in the receiving casing 35. . Then, the worker A transfers it to the transport vehicle 36, and the worker B takes out the cloths 7 one by one from the transport vehicle 36 and causes the clamps 41 of the feeder conveyor 4 to grip them so that they are fully unfolded by the unfolding device 5. It is sent to Ironer 6 and finished.

As a result, when the rectangular cloth is taken out from the dryer, the rectangular cloth is loosened to some extent from the agglomerated state. Further, it is conveyed by the belt conveyor 2 and receives the receiving casing 35.
Since it is unwound from the rolled state even when it is dropped inside, the cloth piled up in the receiving casing 35 is in a state of being easy to take as a single item. The worker A unravels the rectangular cloth, picks up the sheets one by one, and stores them in the carriage 36.
When is full, carry it to worker B. The worker B takes out the cloths one by one from the inside of the carriage 36 and causes the clamps 41 of the feeder conveyor 4 to grip them. In this state, the rectangular cloth is completely unraveled, so the operator B has to find only one corner of the taken out cloth. Furthermore, as equipment for automatic mechanization without human labor, one corner is automatically searched for from the nodular rectangular cloth that is sequentially taken out from the dryer, and the one corner is held and hung in a rod shape. A rectangular fabric corner take-out device which can be lowered and can perform such work in a relatively small space is disclosed in JP-A-5-208100.
It has been proposed in the publication. However, this device has a complicated structure in which, in order to take out a corner of a rectangular cloth, the cloth is held many times to search for the position of the corner and the operation of holding the cloth is repeated.

[0005]

SUMMARY OF THE INVENTION As described above, the conventional work for spreading rectangular cloth is to wash sheets, wrapping cloth, etc. with a continuous washing machine, and then dry with a dehydrator to dry them into a nodule. Since it is a manual work in which the rolled product is taken out from the dryer in a rolled state, unfolded and then sent to the ironer, there is a drawback that a large number of people are required. Therefore, there has been a demand for a linen supply device, such as sheets, which has a low investment cost and good workability, with the aim of increasing the productivity with a small number of workers by changing the procedure of this work. In the conventional example shown in FIG. 5 and FIG. 6, the workers A are piled up in the receiving casing 35, the worker A transfers them to the carrier 36, and the worker B takes out the cloths 7 one by one from the carrier 36. By taking out only one corner of the rectangular cloth and holding the two adjacent edges by the clamps of the feeder conveyor, the unraveling work of the cloth is simplified, but this also requires manual labor. There are drawbacks such as a lot of work and low productivity. In addition, the above-mentioned Japanese Unexamined Patent Publication No. 5-208810
The example shown in Japanese Patent Publication No. 0 is an automatic machine facility in which one corner portion is automatically searched sequentially from a nodule-shaped rectangular cloth, and the one corner portion is held and hung in a rod shape. However, it was complicated and expensive, and the installation space was still quite large. The present invention provides a linen supply turntable device that does not require a downstream worker to search for one corner end of linen when the linen is taken out of the linen storage area and held by a clamp of a hanging conveyor. Is to solve.

[0006]

Therefore, according to the present invention, a linen supply device for supplying laundry (linen) such as sheets to a linen development conveyor device in the pre-process of the ironer after washing and semi-drying the upper surface is provided. A circular turntable provided with a large number of linen storage areas partitioned by equally-divided partition plates so that each loosened linen can be placed, and a drive reduction motor provided at the bottom of the circular turntable, The deceleration motor is configured with a control mechanism for intermittently operating at the pitch of the partition plate, and a gripping tool capable of gripping one corner end of the laundry is provided on the upper part of the turntable at the upper part of each linen yard. In addition, a reflective plate is placed on each flat linen storage area of the turntable, and the presence or absence of laundry is checked on a line perpendicular or diagonal to the surface of the reflective plate. A photoelectric sensor is installed, the presence or absence of the laundry at the laundry take-out position is confirmed, and intermittent operation control is performed to advance the next rotation. This is the means for solving the problem. It is a thing.

[0007]

[Function] Laundry of linen such as sheets is washed and dehydrated,
After being semi-dried by the drier, the sheets are transferred from the drier to the transfer conveyor in the form of a nodule, transported and dropped on the pedestal placed under the conveyor. An operator places linens one by one in a linen storage area partitioned by the supply turntable, with one corner end pinched and its knob end facing upward. When the supply turntable is intermittently turned around and stopped, another operator grasps the corner end of the linen, removes it from the linen storage area of the supply turntable, and causes it to be grasped by the clamp of the linen hanging conveyor of the linen spreading device. Since this other operator does not need to search for one corner end of the linen, the work does not take extra time and the processing capacity increases. After the linen is unfolded with a linen spreading device, it is sent to the ironer and ironed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. FIG. 1 and FIG. 2 show a first embodiment of the present invention. FIG. FIG. 2 is a plan layout diagram, and FIG. 2 is a perspective view of a work state using the turntable 11 and devices around it. The circular turntable 11 is provided with a large number of linen storage areas 12a partitioned by partition plates 13 at equal intervals along the circumferential direction. 1 and 2, the sheets 7 are washed by a continuous washing machine (not shown) and dehydrated by a dehydrator (not shown). After being conveyed, they are put into the dryer 1 collectively. The sheets 7 that have been semi-dried in the dryer 1 are transferred to the transport conveyor 2 and subsequently the receiving table 3
Be dropped by. Here, the worker C picks up the sheets 7 one by one (single sheets are referred to as sheets 7 '), and the sheets 7 are placed in the sheets storage area 12a partitioned by the partition plate 13 of the circular supply turntable 11 of the present invention. Place it so that you can see the corners of '. The turntable 11 is intermittently rotated at a pitch for each sheet storage space 12a, and the worker B grips the corner end of the sheet 7'which has come around and attaches it to the sheet suspending conveyor 4 of the sheet developing device 5. The clamp 41 for gripping the one-corner end and the edge close to the one end is gripped. The sheet suspending conveyor 4 draws one end of the sheet 7'into the sheet developing device 5, which fully develops the sheet 7'and sends it to the ironer 6 for ironing.

Next, the structure of the supply turntable 11 will be described. The supply turntable 11 of the first embodiment.
Since the cover 28 and the clip 29 are removed from the turntable 11 in the second embodiment shown in FIGS. 3 and 4, the description will proceed with reference to FIGS. 3 and 4. A partition plate 13 is attached to the upper surface of the rotary base plate 12 of the turntable 11. The partition plate 13 is divided into 12 to 18 equal parts,
It is desirable to divide it into 16 equal parts. Further, the workability is good when the height of the rotary base plate 12 is 65 cm ± 10 cm and the diameter is 2.0 m to 2.5 m, preferably about 2.2 m. In the sheets storage space 12a partitioned by the partition plate 13, the loose sheets 7'can be placed one by one. Rotating base plate 12
Is attached integrally with a driven pulley 15 fixed to the rotary shaft 14, and the driven pulley 15 is driven by a drive pulley 16 attached to the output shaft of a reduction motor 18 via a toothed belt 17. To be done. Therefore, the driven pulley 1
5 and the drive pulley 16 each have a tooth pattern that meshes with the teeth of the belt 17 on the contact surface with the toothed belt 17, so that relative slippage does not occur during driving. The rotating shaft 14 is rotatably supported by a bearing unit 21 attached to a stand frame 20 and a thrust bearing unit 22. Further, the stand frame 20 is supported by 3 to 4 adjusters 23, and the adjuster 23 can adjust the height of the turntable 11 as a whole.

Further, the boss portion of the drive pulley 16 is provided with a plurality of protrusions 16a evenly on the circumference.
Is designed so that when the protrusion 16a rotates by 1 pitch and the partition plate 13 on the rotary base plate 12 advances by 1 pitch, the deceleration motor 18 is activated each time the proximity sensor 19 senses the protrusion 16a. The rotation base plate 12 of the turntable 11 is separated from the partition plate 13 by restarting the deceleration motor 18 after stopping and holding for a certain time by a timer not shown.
Can be intermittently rotated by one pitch. Therefore, by adjusting the holding time of the timer, the stop time of the rotary base plate 12 can be adjusted and the unit work time can be regulated. Reference numeral 25 is a stop switch for stopping the intermittent operation of the turntable 11 by pushing down the lever. By pushing up the lever 25 and returning it to the original position,
The turntable 11 starts intermittent operation again. Further, a reflecting plate 32 is provided substantially in the center of the flat sheet storage space 12a of the rotary base plate 12, and above the reflecting plate 32,
A photoelectric sensor 31 which also serves as a light source is fixedly provided to an external fixing member. The photoelectric sensor 31 is located on a vertical or oblique line of the surface of the reflection plate 32 at the take-out position of the sheet 7'of the worker B. Therefore, if there are two workers B, two photoelectric sensors 31 are placed above the take-out position of the sheets 7'of each worker B. If the plane of the sheet storage space 12a is mirror-finished, the above-mentioned reflector 32 is unnecessary.

The operation of the periphery of the supply turntable 11 of the first embodiment constructed as described above will now be described. The washed and dehydrated sheets 7'are sent to the dryer 1 in the form of a nodule. In the dryer 1, the sheets 7 are semi-dried, and the sheets 7 unraveled to some extent in the dryer 1 are carried by the transport conveyor 2 in the form of a nodule and dropped on another stacking tray 3. Also at this time, the sheet 7 is loosened so as to be a single body. The worker C takes out the sheets 7'from the stacking cradle 3 one by one while loosening the sheets 7 ', and the sheets yard 12a of the rotary base plate 12 of the supply turntable 11 is removed.
The sheet 7'is set so that one corner end of the sheet 7'is pinched and directed upward. This turntable 12 is a bed room 1
Every 2a, it rotates intermittently at intervals of about 3 seconds. When the number of workers B is two, one worker B places the sheets 7'in every other place of the sheets storage space 12a so as to take out the sheets 7 ', and the photoelectric sensor 31 is adjacent to and above the worker B in the wake. If the sheets 7'are provided so as to receive the reflected light from the sheets storage space 12a and the sheets 7'are not present in both of the adjacent sheets storage spaces 12a and the rotating base plate 12 is rotated, the sheets 7'will be moved to the sheets storage space 12a. The remaining rotation can be prevented and it is safe, and the next rotation start is sure. Further, since the worker B does not need to search for one corner edge of the sheet, the work does not take extra time and one person can process 600 sheets / hour, and two persons can process 1200 sheets / hour.

Next, the supply turntable of the second embodiment will be described. FIGS. 3 and 4 show the second embodiment of the present invention. The supply turntable 1 of the second embodiment
The structure of 1 is the supply turntable 11 of the first embodiment,
A cover 28 and a clip 29 are added, and the clip 29 is provided on the upper part of all the sheet storage areas 12a, but the structure of the other portions is the same as that of the first embodiment, and therefore the description thereof is omitted. To do. As described above, the worker C
Take out the sheets 7'from the stacking cradle 3 one by one,
When one corner end of the sheet 7'is pinched up on the supply turntable and placed on the sheet storage space 12a in the state of being pinched up, the clip 29 grips one corner end of the sheet 7'at the same time. . Since the gripping force of the clip 29 is so small that the corner end of the sheet 7'does not fall off, the rotary base plate 12 rotates and the worker B can more reliably and easily take out the corner end of the sheet 7 '. Becomes The worker B causes the clamp 41 of the sheet spreader feeder to grasp the corner end portion of the taken-out sheet 7 '.

[0013]

As described in detail above, according to the present invention, a worker loosens the linen discharged from the dryer, finds only one corner end of the linen, and places it in the linen storage area of the supply turntable. When the operator grabs the corner edge of the linen and takes it out of the linen storage area of the supply turntable and causes it to be gripped by the clamp of the linen suspension conveyor, the wake-up worker does not need to search for the corner edge of the linen. Does not require extra time and processing capacity increases (for example, 600 sheets / hour per person for clamp gripping work and 1200 sheets / hour for two workers B) In addition to the previous process, it takes 10 for 4 people.
The sheets were processed at about 00 sheets / hour, but it was possible for two people to process 1200 sheets / hour).
