Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a cloth feeding device for sending cloth that has not yet been trimmed to a processing step such as ironing.

(Prior Art) For example, in a known device that processes yukata, yukata, towels, pillowcases, etc. after washing, dehydrating, drying, folding, etc., it is necessary for the operator to correctly guide and set the cloth to the input section. It won't happen. Depending on this setting, the cloth may wrinkle and fold, so the operator must be very careful.Additionally, it is necessary to unroll the cloth before loading it, so it is hard work to load the cloth all at once. Moreover, it requires skill. Therefore, the inventor of the present invention previously developed a device for feeding and filed an application (Japanese Patent Publication No. 1-49520).

(Technical issue) The above-mentioned device is for feeding large cloths such as futon covers and sheets.Of course, it is not impossible to feed small cloths, but it is uneconomical, and it is not possible to feed small cloths. It is difficult to learn about this kind of thing, so it is not suitable.

Therefore, the present invention was developed as a device particularly suitable for small-sized cloths.The purpose of the present invention is to use suction power to accurately hold cloths, regardless of their size, and to automatically transfer them onto a conveyor. Go to,
Moreover, it is an object of the present invention to provide a versatile cloth feeding device suitable not only for small-sized cloths but also for large-sized cloths.

(Technical Means) The purpose is to hold cloths placed from the outside at a holding position, and to transfer the cloths onto a conveyor that carries them, between the holding position and the transfer position to the conveyor. A cloth input device equipped with a reciprocating holder, provided in the holder,
A primary suction means has a suction port on one side for holding the cloth by suction, and is connected on the other side to a vacuum suction mechanism for discharging the airflow flowing in from the suction port, and a conveyor at the transfer position. 2, which is provided at a lower position, has an opening for suctioning and holding cloth that approaches the transfer position, and is connected to the suction mechanism on the other side;
Next, the suction means protrudes from the part of the cloth passed onto the conveyor that extends downward from the passing position.
This can be achieved by providing a spreading means that is in contact with the cloth in the width direction and that spreads out the cloth that provides resistance to the conveying force.

(Example) This will be explained below with reference to the drawings.

In each figure, 1 is the main body of the feeding device, 2 is a conveyor installed in the middle, and in order to carry the cloth W on it, there is a conveyor at the front end of the main body 1 and the opposite end. Consisting of a large number of belts placed on conveyor rolls 3 and 4 installed respectively, a conveying surface 5 is slightly inclined upward until reaching an intermediate roll 6 installed in the middle.
have.

Reference numeral 10 denotes a substantially gate-shaped frame installed on the main body 1 at the upper front of the conveyor. It can be moved in parallel so that two positions can be selected, including the retracted position (dashed line in the figure). The front side has an opening width that is approximately an integral multiple of the width of the holder 11, which is set to a constant width,
When the frame 10 is in the retracted position, the transfer position B on the conveyor is generally exposed.

The holders corresponding to the above multiples are arranged horizontally in a row inside the gate-shaped opening of the frame, and each holder 11 ₁
~ _11o is swingably suspended from an intake duct 12 set in the width direction of the frame. That is, each of the holders 11 ₁ to 11 _o has a flat box shape and has a suction hole 3 consisting of a large number of small holes formed in the front part in a suspended state. The internal hollow part and the intake duct communicate at a contact point with a window 14a formed on the side of the duct and a conduit 14b that overlaps the window 14a and whose opening degree can be changed by rotation. The duct 12 is connected via a suction hose 15 to a vacuum suction mechanism installed inside the main body. The opening area of this window 14a constitutes a holding force variable means 14 that is maximum at the rest position and minimum, almost zero, at the transfer position. 16 is a vacuum suction chamber, 17 is a suction fan, 18
indicates its drive motor. Above intake duct 12
The suction hose 15 constitutes a primary suction means.
Each holder 11 ₁ to 11 _o has a reciprocating motion so that its swing angle changes, that is, it can reciprocate between a holding position A where cloth W is placed from the outside and a transfer position B on the conveyor. A cylinder mechanism 20 as a means is installed respectively. 21 is a lug on the holder side, 22 is a telescopic rod whose tip is pivotally supported, and 23 is a cylinder shaft support end. Each cylinder is attached to the frame 10. 24 indicates a sensor to be described later.

The transfer position B is set at a position on the conveyor that substantially faces the suction port 13 on the front side of the holder 11 when the holder 11 swings, and a suction box 26 having an opening 25 facing downward from the conveying surface 5 is located on the conveyor. is set up. Further, in order to apply suction force to the cloth W through the conveyor, a conveyor belt having a large number of small holes or a net-like conveyor belt is used.
The suction box 26 communicates at both ends with suction hoses 27 into the suction chamber 16 of the primary suction means. The opening 25 to the suction hose 27 constitute secondary suction means.

Reference numeral 30 denotes an opening/expansion means for the input cloth, which is located directly below the input side of the conveyor, and is capable of protruding so as to come into contact with the hanging portion of the cloth W sucked and held at the transfer position B; The same number of holders 11 as described above are arranged in parallel over approximately the same width. The means 30 includes an expanding plate 31 having an arcuate tip that contacts cloth.
₁ to 31 _o , a piston rod 32 connected to the rear end, and a cylinder 33, and furthermore, a piston 35 and a cylinder mechanism 36 for similarly extending similar expansion plates 34 ₁ to 34 _o are provided at the bottom thereof. It is attached.

Reference numeral 40 denotes a front receiving chamber provided in the main body below the input end of the conveyor, and this chamber 40 also serves as a duct for sucking cloth into the interior from a suction port 41 at the upper end, and by this downward suction, the portion where cloth is not held is removed. Pull it downward to help correct your appearance. A communication duct 42 communicates with the suction means, and a baffle plate 43 in the middle relieves the suction force. Further, the suction port 41 opens and expands 44 toward the front, and a guide roll 45 for guiding the cloth holding portion to the front receiving chamber 40 is provided therein so as to be rotatable around a horizontal axis.

Therefore, the suction/holding force of the primary suction means at the holding position A of the cloth is weaker than the suction/holding force of the secondary suction means at the transfer position B, and the suction/holding force at the positions A and B is lower than that of the secondary suction means. The opening/expanding means 30 are set to operate sequentially in conjunction with pressure detection by the sensor 24 described above. In other words, an increase in the pressure in the holder due to completion of storage and a decrease in pressure due to the next transfer are sensed and detected, and signals are issued to activate each mechanism.

(Function) In the device of the present invention configured as described above, when the cloth W is pressed from the front against the holder 11 at the rest position A, the tip of the cloth is drawn by the airflow sucked from the suction port 13. It is held at the maximum holding force of the holding force variable means (FIG. 6). When the completion of this holding is detected by the sensor 24, a signal is sent to the holder 11.
oscillates, and as a result, the leading end of the cloth approaches the transfer position B on the conveyor, and the holding force gradually weakens and finally reaches zero, so it is transferred onto the conveyor 2 by the suction force. This is the case (Figure 8).

After the rest position and until the end of handing, the unheld part of the cloth other than the tip hangs down from the conveyor input end, but the guide roll 45 introduces this part into the front receiving chamber 40, where it is In response to the downward suction force, the cloth is also pulled downward and flutters, so that the cloth is stretched in the front and back direction by the conveyor conveyance force and the suction force, and is also pulled in contact with the spreading means 30,
Since the arc pushes the cloth outward from the center to the left and right, even if the cloth has wrinkles immediately after washing, it can be smoothed out and ideally loaded and transported.

(Effects) Therefore, according to the present invention, the worker can simply place the tip of the cloth in the holder, and the cloth can be kept in the correct shape without having to spread and fan it as in the past. Because it is loaded and transported, pretreatment is not required and the work is significantly reduced.It is also suitable for small fabrics such as pillowcases, napkins, and towels, as well as large fabrics such as sheets, and can be used for small fabrics. Not only is it not uneconomical to do so, but it also allows several people to line up and perform individual input operations, thereby significantly improving work efficiency.
