Description

  The present invention relates to a cloth shaping apparatus in a cloth throwing machine that throws a washed cloth into a process in a trimmed state.

  For example, in a service that collects used cloth from a requested hotel, inn, or hospital, washes it, and folds it for delivery, it is an important factor to deliver the cloth without any defects. is there. Among the fabrics, those with a frame shape called frame wrapping are used for futon covers, and the inner edge corresponding to the inner frame of the frame is not supported by anything, so the lower part hangs down. This is likely to cause the problem of wrinkles (see FIG. 1 or FIG. 6). Conventionally, it has been pulled and tensed to the left and right by manual work, but the problem is that the hands of the two workers are blocked.

  Even for cloth, for clothes such as gowns, there has been an input machine that uses a mannequin type molding machine, and it is common practice to input the clothes while keeping a figured state. Even if it is a wrapping cloth, it is easy to obtain a well-dressed state with a wrapping cloth called a whole wrapping cloth or a bag-like structure. It was something that had to rely on human hands.

  Under such circumstances, the applicant previously developed a shaping device for frame wrapping and filed an application (Japanese Patent Application No. 2004-130357). In the invention of the same number, a brush-shaped shaped body is provided on the front side of the cloth, a belt-shaped part is provided on the back side of the cloth, and the front side of the cloth supported by the belt-shaped part is disposed on the front side of the cloth. It has a constitution means of removing the wrinkles by pressing with. However, since the brush-shaped shaped body is point-shaped with respect to the size of the cloth, the cloth may turn over without being pressed by the shaped body. There was a problem of poor stability. In addition, this kind of cloth feeding device is used in combination with a folding device, and the number of cloths to be thrown in is not limited to one, and there are various forms. It may not fit the form and in some cases may be annoying.

The present invention has been made paying attention to the above points, and the problem is that it has a special structure such as a frame wrapping cloth, and even if the cloth is different in size, it is sure to be in a well-shaped state. It is possible to provide a cloth shaping device in a cloth feeding machine. Further, another object of the present invention is to obtain a dressed state and insert the cloth without requiring any manual operation after the cloth is set in the charging machine.

In order to solve the above-mentioned problems, the present invention provides a cloth feeding machine for throwing a washed cloth into a process in a trimmed state,
In order to remove wrinkles generated in the subsequent part of the cloth fed from the front to the feeding conveyor, it is provided in the apparatus main body at a position where it can come into contact with the back of the cloth and moves from the center to the left and right. In order to remove the wrinkles, the expansion part that acts in the direction of spreading the cloth, and the cloth can be contacted with the front of the cloth, and the cloth can be pressed against the expansion part that can contact the back of the cloth. The expanding portion is formed by a suction means that is attached to the back surface of the cloth and is movable leftward or rightward from the center of the feeding portion. It has an elongate belt-like part, and the presser part is formed to be elongated in the left-right direction so that the front part of the cloth is uniformly pressed over the entire area in the direction crossing the feeding direction, and the outer edge of the cloth in the left-right direction Left and right separately at the position protruding outward, left Pressing unit is provided movably so as to be separated into contact moves back and forth relative to the expanded portion by the pressing portion longitudinal cylinder, and also to the left and right side toward the moving mechanism, to be in contact with the textiles If there is not, as a presser part moving means to move the presser part to the retracted position away from the cloth and move it to the work position where it can contact the cloth when necessary, pivotally support one end on the presser part storage base, It has a presser part storage cylinder with the other end attached to the cloth feeder, and the work position that can contact the front of the cloth and the cloth cannot come into contact with the operation of the presser part storage cylinder. with taking a retracted position, to move the pressing portion back and forth in the working position, in which took measures that thereby you configured to press the pressing portion in textiles.

  When the cloth feeding machine attaches both ends of the front part of the cloth to the clamp etc. at the attachment part, the clamp etc. moves to carry the cloth and accurately places it at the feeding position in front of the feeding part. Is a device that guides and forwards the front part of the cloth by a guiding device onto the input conveyor. The clamp for attaching the cloth may be different from or the same as the clamp for arranging the cloth at the input position in front of the input section. Is delivered. With respect to such a technique, for example, those described in Japanese Patent Application Laid-Open No. 11-192400 and Japanese Patent Application No. 2002-255504 which is a subsequent technique can be applied. The cloths are put into the input conveyor by the induction device, and transfer to the input conveyor from the front to the rear according to the operation of the input conveyor, thereby completing the input process.

  An expanding portion is provided that contacts the back side of the cloth and moves in the left-right direction from the center. This is in order to remove wrinkles generated in the subsequent portion of the cloth that is input from the front part to the input conveyor. When the front part of the cloth is attached to a clamp, etc., it hangs down to the front of the input device, but as shown in Fig. 1, the tension does not reach the lower part from the front part pulled by the clamp, etc. Prone to wrinkles. The wrinkles are conspicuous in the lower half of the hanging fabric, and are particularly prominent on the lower side of the so-called frame-like portion having a double-sided structure. Therefore, in the present invention, the cloth is spread from the back to the left and right by the widening section, and the widening section can be configured, for example, by providing a pair of right and left widening belts in front of the feeding section. The spreading belt is a wrinkle removing means or deformation correcting means on the back side of the wrapping cloth and other cloths, and operates to spread the cloth from the center to the left and right sides by moving to the left and right. The deformation is corrected.

  Furthermore, special shaping is necessary for those in a delicate state where the edge of the lower part of the frame part is drooping like a trailing part of the frame wrapping. In the present invention, a presser portion is provided to remove the wrinkles. The presser part can contact the front surface of the cloth of the subsequent part and acts in the direction of pushing the cloth against the widened part of the back surface by contact. On the back side, the spreading action is spread in the left and right directions by the spreading section, so that the spreading action is evenly transmitted to the fabrics. For this reason, it is necessary for the presser part to hold the target part that requires correction of the front part of the cloth evenly over the entire area, and it is formed to be elongated, and its end part is further from the outer edge rather than ending on the cloth. It is desirable to protrude outward. If the spreading force of the spreading part acts on the back side of the cloth being pressed by the presser part that is too short, it may be pulled or turned over. This tendency becomes more prominent, but it has a length enough to hold the entire area where the wrinkles are generated, and it protrudes further outward than the outside of the cloth. By providing conditions, it is possible to avoid problems such as pulling and turning.

The presser part can be provided so as to be movable by a moving mechanism from the front center part of the charging machine to the left and right sides. The moving mechanism is for moving the presser part from the center side of the insertion part to the left and right sides, but a specific configuration can be arbitrarily selected. For example, a known reciprocating mechanism using a pulley, a belt, a chain, a sprocket wheel, a piston cylinder device, and a motor can be applied as the moving mechanism of the present invention. A moving mechanism has the objective for pushing and moving a shaping body right and left in the target location of cloth. However, there are cases where the shaped body only needs to be pressed against the cloth and does not always move.

  The presser portion has, for example, a brush-like, sponge-like or other member as a means that can come into contact with the fabric by appropriate friction. Further, the spreading belt is used as a receiving portion for receiving the force with which the shaping body presses the cloth. Further, as the spreading belt, a belt-like portion having a suction hole for making contact with the back surface of the cloth and capable of being adsorbed to the back surface can be arranged in the left-right direction in front of the feeding portion. In this case, since the cloth is temporarily fixed by the suction means by the suction means, when having a front and back double structure like a wrapping cloth, the back face without deformation can be fixed by the suction means, As a result, the shape of the surface of the cloth is also corrected, and the front side of the cloth only needs to be pressed by the pressing portion at the target portion. Further, even if the front surface is pushed by the pressing portion, it is prevented from moving to the back surface.

  Thus, the expansion belt, which is a means for fixing cloth by suction and is also a means for removing wrinkles or a means for correcting deformation, further serves as a belt-like portion as the receiving portion. The belt-like part in the present invention corresponds to a chain, and receives the pressing of the cloth by the holding part, and includes all of the belt-like objects in addition to the literal belt. Thus, the movement of the presser portion is enabled by an elongated structure.

  Since the pressing portion has a function of pressing the cloth from the front, it is arranged at a position relatively close to the receiving portion of the dosing device body. However, there is a possibility that the cloth will be caught if it is too close, and in order to prevent this, a position switching means is provided so that the work position and the retracted position of the press part can be taken, and the press part is provided on it. . In addition, the clamp part can be moved to a position away from the cloth so that it does not hinder the movement of the cloth while it is being conveyed by the clamp, and it can be placed at a position where it can contact the target location of the cloth during shaping. To do.

  Since the present invention is configured and operates as described above, the pressing portion is in contact with the rear portion of the fabric that has not yet reached the input conveyor, and the target portion has a necessary and sufficient length and area. Since the fold is stretched by the expansion part while maintaining the state, even if it is a cloth having a special structure such as a frame wrapping cloth, it can easily and surely obtain a figured state, Therefore, according to the present invention, after the cloth is set in the feeding device, it is possible to obtain the dressed state and perform the feeding without requiring a manual operation.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 and FIG. 2 are a plan view and a front view of a cloth feeding device to which the present invention is applied, and cloth attaching portions 10 are set on the left and right sides of the front, respectively. The cloth attachment portion 10 is provided with two pairs of input clamps 11, 12, 13, and 14 respectively. These clamps 11, 12, 13, and 14 are provided upward, in the transfer portions 15 and 15 '. The cloth W is moved to the upper delivery position 16, 16 'and has a configuration and function for delivering to the spread clamps 17, 18, 19, 21.

  The spread clamps 17, 18, 19, and 21 are for setting the cloth W to the left and right in front of the feeding portion, which is set in the upper front portion of the cloth feeding device, and assisting the loading. Further, the expansion clamps 17, 18, 19, and 21 run on the guide rails 20 of the expansion mechanism installed on the left and right slightly above the input portion on the front of the apparatus main body. FIG. 1 and FIG. Only the traveling locus is shown. Note that the spread clamps 17, 18, 19, 21 clamp the tip e 1 of the cloth W, and release the cloth W clamp when the cloth W is loaded into the loading conveyor 22.

An expansion portion 23 that contacts the back surface of the cloth W in advance and enters the cloth W in the direction to expand left and right before being put into the process is provided at a position where it can contact the back surface of the cloth W. As the widened portion 23, a pair of belt-like portions 25 and 26 that are elongated on the left and right are provided on the left and right sides. Each belt-like part 25, 26
3, each has a box frame 24, pulleys 28 and 29 pivotally supported on both right and left ends thereof, and an expansion belt 30 wound around them. The suction hole 41 is opened, and the cloth W is adsorbed on the back surface by suction means using the box frame 24 as a ventilation duct so that it can be temporarily fixed. The spreading belt 30 is provided to receive an input from a driven pulley 32 attached to the shaft 31 of one pulley 29 and to rotate in one direction from the front center side of the input portion to the left or right respectively. . Reference numeral 33 denotes a drive pulley, which is connected by a driven pulley 32 and a transmission belt 34, and rotates by rotation of the output shaft of the motor 35.

  The exemplary device has a damper device 40. The damper device 40 includes a damper piston cylinder device 37 for controlling the suction action, and a damper 38 having a moving end connected to the piston side and attached to the box frame 24 at the rotating shaft portion. The suction action of the cloth W through the suction conveyor 39 is controlled. The suction force with respect to the expansion part 23 has an adjusting device so as not to be affected by the influence of the damper device, and communicates with the suction machine 44 through the same suction hose 43. Reference numeral 42 denotes a negative pressure reservoir that leads into the box frame, 43 denotes a suction hose extending therefrom, and 44 denotes a suction machine.

  As illustrated in FIG. 1, the frame wrapping cloth, which is one type of the fabric W handled in the present invention, tends to sag X at the lower edge of the frame portion. Therefore, in the present invention, a pair of left and right pressers 51 and 52 are provided in order to tension the rear part in the frame wrapping movement direction in which the wrinkles X are generated in the left and right direction orthogonal to the movement direction. Each presser part 51, 52 is provided in front of the input part, and the illustrated ones are installed on the left and right of the input part, respectively, and are attached to the moving parts of the moving mechanisms 53, 54.

The illustrated presser portions 51 and 52 are provided separately on the left and right sides as shown in detail in FIGS. 1 and 2. Further, similarly to the base frame 55, the holding portions 51, 52 that are elongated in the left-right direction are attached to the guide portion 57 that is movable along the guide rail 56 that extends in the left-right direction, and attached to the other end side of the base frame 55. A part of the sliding cylinder device 58 is connected to the guide portion 57 as a moving portion, and the operation of the sliding cylinder device 58 is configured so that the target location on the front side of the fabric W can be moved to the left and right sides. (FIG. 5). Each moving mechanism 53 is moved to a state that is completely accommodated in the base frame 55, with spaced to place the cloth between, the after cloth W is carried into the on position, it Is provided so that the working position and the retracted position can be taken by the position switching parts 59 and 60 so that the presser parts 51 and 52 do not get caught (see FIG. 9). The position switching portions 59 and 60 have a presser portion storage cylinder 62 having one end pivotally supported on the presser portion storage base 61 and the other end attached to the cloth feeding machine side. The work position where 51 and 52 approached so that contact is possible, and the retreat position located in the position which was separated so that cloth W could not contact are taken. The presser part storage base 61 is provided with a presser part front / rear cylinder 63, which moves the presser part back and forth at the work position so that the presser parts 51 and 52 can be pressed against the cloth W.

In such an apparatus of the present invention, the cloth W is attached to the closing clamps 11, 12, 13, 14 at the cloth attaching portion, and then automatically delivered to the spread clamps 17, 18, 19, 21; It is transported to the center of the front of the device body. In this state, the presser portions 51 and 52 are switched to the working position by the switching means 59 and 60, and the cloth W is stretched at the left and right ends of the upper end portion and is tensioned to the left and right by the clamps 17, 18, 19, and 21. Although there is no slack, the lower end portion hangs down from the inner edge at the lower part of the frame portion at the lower end portion to form a collar X (FIG. 6). Therefore, when this apparatus is activated, as shown in FIG. 1 and FIG. 2, the presser portions 51 and 52 that have been separated from the cloth W to the left and right sides and have been in the retracted position so as not to obstruct the passage of the cloth W are slid The cylinder devices 58, 58 are moved from the left and right sides toward the center by the operation of the cylinder devices 58, 58, and can come into contact with the frame portion of the cloth W (right side in FIG. 9). At the same time, in the inside of the apparatus, the suction action to the back of the cloth by the suction means is performed through the suction hole 41 of the expansion part 23, and the cloth W is fixed weakly and not deformed. The spreading action is exerted particularly on the frame portion of the cloth W. At that time, the presser portions 51 and 52 are moved to the left and right sides by the moving mechanisms 53 and 54. By the pressing movement by the presser portions 51 and 52, the fabric W is strained to the left and right at a position slightly below the inner edge, and is almost linear. As a result, the drooped portion is also pulled up and the heel X disappears (FIG. 7B).

  In the above state, since the cloth W is only suspended by the spread clamps 17, 18, 19, and 21, if the wrinkle removing action by the presser portions 51 and 52 is received, the material and structure of the cloth W, etc. Depending on the conditions, the back side may be affected. Therefore, in the present invention, the suction means provided in the belt-like portions 25 and 26 as the receiving portions is activated so that the back surface of the cloth can be vacuum-sucked. By holding W, the cloth W is secured on the back surface, and this also makes it possible to more reliably achieve the action of removing the wrinkles on the cloth W by the presser portions 51 and 52.

  In the above-described work of removing the ridge X by the presser portions 51 and 52, the presser portions 51 and 52 sandwich the cloth W with the belt-like portions 25 and 26 on the spreading portion side with a uniform acting force over the entire area. Then, the belt-like portions 25 and 26 expand the left and right sides of the cloth W under such a sandwiched state. In this case, if the front presser is spot-like with respect to the belt on the back as in the conventional case, if the pressing force is weak, the moving force of the belt-like part on the back will win and the fabric will slide. If the pressing force is strong, the cloth will come off and will move and will rub one point. In addition, the moving force of the belt-shaped part on the back and the pressing force on the front surface do not balance, and because it is a spot-like presser, the double-side back cloth is turned to the front cloth side at the outer edge of the fabric W. Sometimes it becomes. However, in the present invention, the frame-like portion of the cloth W extends over the entire width, and the belt-like portions 25 and 26 on the back face are uniformly pressed by the presser portions 51 and 52 on the front face. There is nothing.

  There are various types of fabrics W, and there are also size differences such as large, medium, and small in the same shape. In order to obtain the best results according to the present invention for these fabrics W, information on the shape and size of the fabrics W that have been input is obtained in advance, and the presser portions 51 and 52 and, if necessary, the belt shape. The positions of the portions 25, 26 can be adjusted so that they fit exactly in the required position, such as the frame portion of the fabric W. It is easy to add such a position adjusting device, and it can be performed by a known technique.

  The apparatus of the present invention is effective as described above for the input of the cloth W such as a wrapping cloth or a frame wrapping cloth, but can be similarly applied to a sheet made of a single cloth. The cloth W made of a single cloth also enters the input conveyor 22 from the tip, but the cloth W held by the spread clamps 17, 18, 19, and 21 is provided on the front end of the input conveyor so as to be able to advance and retreat. While the suction part is moving forward, the leading end of the cloth is sucked and held over almost the entire width, and is retracted, and is transferred onto the input conveyor with the help of a jet from an air nozzle (not shown), and gradually as the input conveyor 22 operates. It is conveyed to. Meanwhile, the cloth W such as a sheet is subjected to the suction holding action by the suction means, and is also subject to the action of stretching the vertical folds to the left and right by the movement of the spreading belts 30 and 30 to the left and right. More effective shaping can be performed by a synergistic effect with the belts 30 and 30. However, since the cloth W such as a sheet does not need to be acted on by the pressing portions 51 and 52, the pressing portions 51 and 52 are stored in the retracted position shown on the left in FIG.

  FIG. 10 shows an example in which left and right separating rolls are arranged so as to draw a shallow V-shape at the lower portion of the charging unit. The separating rolls 65 and 66 roll up the lower portion of the fabric W relatively quickly, A shaping mechanism for forcing the lower part of W from the front side to forcibly get over the rolls 65 and 66 to the back side is shown. The rolls 65 and 66 can be changed in posture either in a V shape or in a straight line. However, for the above shaping operation, the V roll shape is assumed to be taken up. By gathering closer to the center and then descending and spreading, the lower part of the fabric W is to be corrected.
