DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is to spread relatively small area cloths such as towels and pillow covers,
The present invention relates to a cloth stretching and transporting machine for transporting the stretched state to a next process device such as a press machine or a folding machine.

[0002]

2. Description of the Related Art In a laundry factory, after washing and drying a large amount of cloth such as towels and pillowcases, the work of pressing with a press machine or folding with a folding machine is performed. However, when the cloth is supplied to the subsequent process device (press machine or folding machine), it is necessary to spread the cloth neatly in advance. The cloth after washing and drying has an irregular shape due to being twisted or folded.

[0003] By the way, cloths such as towels and pillow covers are supplied to the next process apparatus in an expanded state.
Generally, the following operation is performed using a cloth conveyor as shown in FIGS. It should be noted that the cloth transporter of FIG. 7 has two cloth loading work positions on the left and right.

In the conventional example shown in FIGS. 6 and 7, one cloth S is taken out from a pile of cloths R (FIG. 7), and a front edge portion which is one short side of the cloth S is taken out. The both ends of Sa are searched for, extended with both hands to the left and right, and the cloth leading edge Sa is placed on the starting end 21 of the conveyor 2 (FIG. 6).
State, and the working state on the right side in FIG. 7). Then, as the transport conveyor 2 is running, the cloth hanging parts Sc are sequentially fed onto the conveyor 2. At this time, the cloth hanging parts Sc are sequentially moved with both hands in accordance with the degree of transfer. And spread downward (side edges Sb, Sb of the cloth)
To the left, right, left and right. The work of extending the hanging portion Sc of the cloth is continued until the trailing edge Sd of the cloth S is pulled up near the conveyor start end 21 as shown in the left-hand working state in FIG. In this way, the cloth S can be post-conveyed on the conveyor 2 in a state where the cloth S is stretched neatly into a rectangle. Then, the next cloth S is taken out of the cloth group R and sequentially placed on the conveyor 2 in the same manner. In addition, a next process device such as a press machine or a folding machine is connected to a terminal portion of the conveyor 2, and the spread cloth is automatically supplied to the next process device from the terminal portion of the conveyor 2.

However, in the conventional cloth conveyor shown in FIGS. 6 and 7, in order to spread the cloth S neatly on the conveyor 2, the cloth front edge Sa is placed on the conveyor start end 21. After that, it is necessary to sequentially and manually spread the cloth hanging portion Sc right and left until the cloth rear edge Sd is pulled up near the conveyor start end 21. Therefore, in this conventional cloth transporter, the hanging work for spreading the cloth is troublesome, and during the hanging work, the next work (the work for taking out the next cloth and the leading edge portion) is performed. Search operation), the work efficiency was poor.

FIG. 8 shows another conventional cloth spreading and conveying machine. 8 is used in a cloth folding machine already proposed by the present applicant (Japanese Patent Laid-Open No. 9-255137), and includes a starting end 21 of the conveyor 2. A vertical suction chamber 3 is provided immediately below the suction chamber 3, and the air in the suction chamber 3 can be sucked downward by a suction machine 4. The front wall 32 of the suction chamber 3 protrudes from the front end 21a of the conveyer starting end 21 by a suitable width toward the front side (cloth loading work position side). On the upper end of the suction chamber front wall 32, the cloth S placed on the conveyor starting end 21 is placed.
A feeding roller 5 for feeding the hanging part Sc of the suction roller 3 into the suction chamber 3 is provided. This feeding roller 5 is moved in the direction of the arrow (FIG. 8).
In this state, it rotates at high speed in the clockwise direction. The front end face of the feed roller 5 is connected to the front end 2 of the conveyor start end 21.
It protrudes toward the near side by a predetermined width L (L = about 150 mm, for example) from 1a.

In the conventional cloth spreading and conveying machine shown in FIG. 8, when the leading edge portion Sa of the cloth S is placed on the conveyer starting end 21, the cloth hanging portion Sc is fed by the feeding roller 5.
When the feeding roller 5 is rotating at a high speed at this time, the cloth hanging portion Sc is fed into the suction chamber 3 as shown by the reference numeral Sc ′, and the air in the suction chamber 3 is further Is sucked downward (in the direction of the arrow W), so that the hanging portion of the cloth flaps and is stretched downward as indicated by the reference numeral Sc ″, and then the hanging portion Sc ″ of the cloth
Are sequentially pulled up on the conveyor start end 21 in the expanded state.

As described above, in the cloth spreading and conveying machine shown in FIG.
The cloth can be automatically spread on the conveyor 2 simply by placing the cloth leading edge Sa on the conveyor start end 21. Therefore, immediately after the cloth leading edge Sa is placed on the conveyor start end 21, the next cloth can be taken out and the end can be searched for, so that the work efficiency is higher than that of the conventional example shown in FIGS. Is good.

By the way, in the conventional cloth spreading and conveying machine shown in FIG. 8, the cloth can be automatically expanded only by spreading the cloth front edge Sa left and right and placing it on the conveyor starting end 21. The front wall 32 of the suction chamber 3
(Especially the feeding roller 5) is the front end 2 of the conveyor start end 21.
It is fixed in a state of protruding toward the front side (left side in FIG. 8) from 1a. In particular, the front end face of the feeding roller 5 has a width L (for example, 150 mm) from the front end 21a of the conveyor start end 21.
(approx. mm). Therefore, in this cloth transporter, there is a problem that the portion (the feeding roller 5 and the suction chamber front wall 32) projecting further forward than the front end 21 a of the conveyor start end 21 when the operation is stopped is obstructed. Some cloths to be treated have a relatively small area such as a napkin. When the cloth having such a small area is transported by the cloth transporter, the suction chamber 3 is used.
The cloth hanging portion Sc can be expanded relatively easily without performing the work of extending the hanging material portion Sc by the above method. 5 and the front side protruding portion such as the suction chamber front wall 32 become an obstacle.

[0010] In view of the above-mentioned conventional problems, the present invention does not operate even if a suction chamber for extending the hanging portion of the cloth is provided immediately below the start of the conveyor as in the conventional example of FIG. It is an object of the present invention to provide a cloth spreading and conveying machine which can prevent the front wall of the suction chamber from protruding forward from the front end of the conveyer starting end when the work of expanding the hanging part of the cloth by the suction chamber is not necessary. And

[0011]

The present invention has the following structure as means for solving the above-mentioned problems. still,
The invention of the present application is to spread cloth of relatively small area, such as towels (face towel, bath towel, etc.) and pillow cover, and to transport the cloth in the expanded state to the next process side. The machine is targeted. The cloth spreading and conveying machine according to the first aspect of the present invention includes a conveyor that can handle cloth on the conveyor start end and can postpone the processed cloth, and an upward direction below the conveyor start end. It has a vertical suction chamber that opens, and a suction device that sucks air in the suction chamber downward.

[0012] The starting end of the conveyor is a portion into which cloths are manually inserted, for example, from 80 to 100 meters from the floor surface.
It is provided at a height of about cm. The leading edge, which is one side of the cloth, can be placed on the conveyor start end by hand from the cloth input operation position. In addition, a subsequent process device such as a press machine or a folding machine is connected to a terminal portion of the transport conveyor.

The suction chamber is for dropping a rear portion (hanging portion) of the cloth while the front edge of the cloth is placed on the start end of the conveyor, and is located immediately below the front end of the start end of the conveyor. Has an opening of the suction chamber. The air in the suction chamber is sucked downward by the suction machine, and the hanging air flow can expand the hanging portion of the cloth dropped into the suction chamber.

The suction chamber has a front wall facing the cloth loading work position. Then, the front wall can be displaced back and forth between a use position protruding from the front end of the conveyor start end toward the cloth loading work position side and a storage position retreating deeper than the front end of the conveyor start end. Installed in This front-rear displacement operation of the front wall may be one in which the upper end of the front wall swings back and forth, or one in which the entire front wall slides back and forth. The front-rear displacement operation of the front wall may be performed using power (for example, a telescopic cylinder) or may be performed manually.

The cloth spreading and conveying machine according to the first aspect functions as follows. When the front wall of the suction chamber is projected to the use position (front side), an opening for sucking cloth is provided between the front end of the conveyor start end and the upper end of the suction chamber front wall.
When the suction device is operated in this state, air is sucked downward from the opening between the front end of the conveyor start end and the upper end of the front wall. Then, when the leading edge of the cloth is placed on the start of the conveyor, the rear portion of the cloth closes the opening, and the leading edge of the cloth is placed on the start of the conveyor by suction from the opening. The rear part of the cloth (cloth hanging part) is drawn into the suction chamber and hangs down while being placed on. At this time, the hanging portion of the cloth flutters due to the suction action in the suction chamber, and the hanging portion of the cloth is spread cleanly. Subsequently, by the traveling of the transport conveyor, the hanging portion of the cloth hanging down in the suction chamber is pulled up in an extended state, and the cloth is fed back in the extended state. As described above, in the cloth spreading and conveying machine of the present application, the cloth is automatically spread and placed only by placing the leading edge of the cloth on the start end of the conveyor.
Can be transported.

On the other hand, when the operation is suspended, if the front wall of the suction chamber is pushed down to the storage position on the back side, the front wall is located on the back side from the front end of the conveyor start end, so that the cloth loading work position Wide space on the side. If the cloth to be treated has a relatively small area of, for example, a napkin, and can be spread relatively neatly without performing the work of extending the hanging part of the cloth by the suction chamber, the front wall of the suction chamber is required. Work can be performed in the storage state. In that case, even with a cloth spreading and conveying machine having a suction function by the suction chamber, the work can be performed in a state where the front wall of the suction chamber is not in the way. The invention according to claim 2 of the present invention is directed to the cloth spreading and conveying machine according to claim 1, wherein a rear portion of the cloth handled on the conveyor start end is provided at an upper end of the front wall of the suction chamber. It is characterized in that a feeding roller for feeding into the suction chamber is provided.

The feeding roller rotates at a high speed toward the feeding side during operation, and when the leading edge of the cloth is placed on the starting end of the conveyor, the rear part of the cloth is moved to the feeding roller. In contact therewith, it acts to quickly feed the rear portion of the cloth into the suction chamber. The outer peripheral surface of the feed roller can be formed of rubber or a brush in order to increase the frictional force with the cloth that comes into contact with the feed roller. According to the third aspect of the present invention, in the cloth spreading and conveying apparatus according to the first or second aspect, a portion around the conveyor start end of the conveyor is provided with air permeability through which air can pass vertically. In addition, air near the upper surface of the conveyor start end is sucked downward by suction from the suction chamber.

According to the third aspect of the present invention, the conveyor start end serving as the cloth feeding section is provided with air permeability. However, in order to provide air permeability, a large number of narrow belts are arranged in parallel at intervals. Or by using a belt with a number of small holes (punching belt). In the case where the entire conveyor is constituted by a series of belts, the entire length of the conveyor will be permeable, but only the conveyor start end, which will be the cloth input section, will be a permeable belt, and other belts will be used. The conveyor section may be non-breathable (in this case, two conveyor belts are continuous).

In the cloth spreading and conveying machine according to claim 3,
In the state where the suction chamber is being sucked by the suction machine, the suction force acts on the upper surface of the conveyor start end, and the cloth placed on the conveyor start end is suctioned onto the conveyor by the suction force. Exercise function. Therefore, even if the hanging portion of the cloth is sucked into the suction chamber, the entire cloth is sucked (falls) into the suction chamber by the suction portion of the cloth being suctioned to the upper surface of the start end of the conveyor. Can be prevented. Further, in the present invention, since the suction effect of the suction device into the suction chamber is used as the suction force on the upper surface of the conveyor start end, the suction force of the suction device can be effectively used. The invention of claim 4 of the present application provides the cloth spreading and conveying apparatus of claim 1 or 2 that imparts air permeability through which air can pass up and down to a portion around the conveyor start end of the conveyor. In addition, a suction device for sucking air near the upper surface of the conveyor start end toward the lower surface side of the upper surface run is provided below the upper run of the conveyor start end.

A suction device according to a fourth aspect of the present invention is also for suctioning a portion on which a cloth is placed on the starting end of the conveyor. You are using In this case, since the upper surface side traveling portion of the conveyor start end can be concentrated and suctioned by the individual suction device, the suction force can be increased, and the cloth-placed portion placed on the conveyor start end can be reliably sucked. .
