Cloth stretch conveying method and apparatus

Technical field

TECHNICAL FIELD [0001] The present invention relates to a cloth spreading and conveying method and apparatus for spreading a large area of cloth such as cloth and conveying the cloth to a next process apparatus such as a press or a folding machine in the stretched state. Is. The cloth in the present invention means a square cloth represented by a sheet, a towel and the like.

Background art

[0002] When a large amount of cloth is washed, treatments such as dehydration, drying, pressing, folding and the like are performed while transporting the washed cloth along a certain line. In particular, when pressing, it is necessary to put the cloths in a pre-stretched state, but it is difficult to spread large cloths without disruption. Therefore, as a conventional spreading and conveying apparatus, the both ends corners of the cloth are grasped by the clamps, moved upward by the lifting means, and then grasped by the both end corners of the cloth in the lateral direction. It has been proposed to transfer to the next process by changing to a clamp to be stretched and transferring the stretched cloth to the next process. For example, Patent Document 1 ).

[0003] However, in the apparatus of Patent Document 1 described above, the feeding device and the stretching device are used until the lower end portion of the cloth transferred onto the conveyor is fed with the starting end force of the conveyor. Since it is not possible to enter a posture to move the cloth and it is in a standby state to match the delivery timing, there is a time lag until the feeding device grabs the next cloth and stretches it on the front of the conveyor by the stretching device. However, there was a problem that the processing capacity of the device was lowered by this time lag, and this time lag also changed depending on the width of the cloth, so that the waiting time was changed and the control was complicated.

In addition, the clamping force for spreading the cloth as described above is also transferred onto the conveyor belt by the suction force from the state where both corners of the cloth are suspended by the clamp. Therefore, the cloth suspended due to the gravity and suction force of the cloth itself is in a state of slack, and this state force moves onto the conveyor, so that the upper edge of the cloth is disturbed and the upper edge of the cloth is There was a certain problem when a uniform situation happened often!

[0004] In view of this, the inventor solved the problem of time lag by providing a transport device having a suction box with a large number of suction holes formed on the upper surface, and also provided a vacuum belt to reduce slack in the fabric. Invented a device to solve this problem (Patent Document 2).

Problems to be solved by the invention

[0006] The inventor aims to solve the following problems in order to improve the processing performance and quality of the apparatus of Patent Document 2.

The first problem is that the receiving chuck performs the process of picking up the cloth and the process of spreading the cloth, so that the cloth cannot be received from the other input side chucks without the stretching process being completed. That is a lot of waiting time.

The second problem is that when the hem of the fabric is sucked in order to supply the stretched fabric to the conveying device without wrinkles, the stretched upper side hangs down due to the suction and the shaping is lost. There is a risk of deterioration.

The third problem is that when the fabric is transferred from the spreading device to the transport device, the fabric may be displaced if the transport device does not have sufficient suction. In the worst case, the fabric may fall. That is. To solve this problem, it is possible to install a device that holds and fixes the upper side after the fabric is stretched, but because the receiving chuck receives the fabric at a position facing the multiple input chucks, There was no space for installing the equipment.

The fourth problem is that when the cloth transfers the transfer device force to the transfer device, the speed difference between the transfer device and the transfer device is sufficient, and the upper side of the cloth may not be transferred and may turn over. is there.

[0007] The present invention solves the above-described problems, and thus has higher processing performance and higher quality than the conventional technology. It is an object of the present invention to provide a method and an apparatus for conveying and spreading fabrics of high quality.

Means for solving the problem

[0008] The method of the present invention is summarized as the following methods (1) to (6) as means for achieving the above object.

(1) Grasping both corners of one side of the cloth with the dosing device and transferring it upward, receiving the dosing device cloth with the traverse chuck, and going to the center position along the first rail arranged on the left and right A pair of chuck forces that can be transferred, received by the delivery device from the traversing chuck, delivered to the expansion device, and moved along the second rails arranged on the left and right. The delivery device force received by the configured expansion device The pair of chucks are separated from each other and stretched left and right, the fabric stretched left and right by the air intake device is stretched up and down, the fabric is received from the stretcher by the horizontal movement device, transferred to the transport device, and transferred to the transport device. The cloth spreading and conveying method that conveys the cloth to the next process.

(2) The horizontal movement device receives the fabric from the stretch device by fixing the hanging portion of the fabric with the upper end fixing bar at the forward movement position and blowing air on the upper side of the fabric. (1) The cloth spreading and conveying method characterized by the above.

(3) The cloth spreading and conveying method according to (2), wherein the suction device extends the cloth up and down when the horizontal movement device fixes the hanging portion of the cloth.

(4) The delivery device has a pair of gripping parts composed of an outer chuck and an inner chuck, receives a transverse chuck force cloth by the gripping part, and rotates each outer chuck to the outside to rotate the cloth. (1) to (3) !, any one of the cloth extending and conveying methods, characterized in that both ends of the corners are stretched by a certain width and the cloth is delivered to the stretching device.

(5) The conveying device is characterized in that the rotational speed of the place where the cloth first contacts is slower than the rotational speed of the place where the cloth is conveyed (1), (4) Any fabric spreading method of transport.

(6) The traverse chuck moves immediately to a position opposite to another feeding device when the fabric is delivered to the delivery device (1) Transport method.

The apparatus of the present invention has the following configuration as means for achieving the above object.

The cloth spreading / conveying machine of the present invention holds the corners on both sides of one side of the cloth, A feeding device that moves to a high position, a cloth that receives cloth from the loading device, and that moves to the center position of the machine along the first rail arranged in the left-right direction, and cloth from the transverse chuck force At the center position of the machine frame, a delivery device that receives the fabric from the delivery device and extends it to the left and right along the second rail that is arranged in the left-right direction, and almost directly below the extension device. An installed intake device that stretches the fabric up and down, a horizontal movement device that receives the fabric from the stretching device and delivers it to the conveyance device, and a conveyance device that receives the fabric from the horizontal movement device and conveys it to the press machine I have.

[0010] The input device includes an input chuck having a pair of gripping portions, and an elevating slide cylinder that transfers the input chuck to a position higher than the height of the person's back. The holding portion of the input chuck is constituted by a pair of spring-biased clip cages. The pair of clips on one side of the feeding chuck are loaded with the corners of the fabric stretched to a certain width, and the other pair of clips are loaded with the other corners on the same side stretched to a certain width. The Multiple input devices are provided to increase the processing capacity.

In the present invention, when the input chuck → the transverse chuck → the center chuck → the spread chuck and the cloth are relayed, the upper side of the transfer portion needs to be extended by the pair of chucks. This is because if the delivery is not performed with the corners of the fabric being extended, the fabric may be delivered in a tilted state at the time of delivery. Also, when the chuck force is transferred to the chuck, the extension width of the transferred chuck is narrowed. Therefore, the input chuck is set so that the width can be sufficiently transferred to the next chuck. It is necessary to design the grip width.

[0011] The traverse chuck can move left and right along the first rail arranged in the left-right direction of the machine frame, moves to a position facing the loading device, receives the cloth from the loading chuck, Transfer to position. At the lower corners of the transverse chuck, there are a pair of gripping parts each consisting of a pair of clips. The gripping portion of the traverse chuck is narrower than the gripping portion of the closing chuck, and when the fabric is delivered, the gripping portion of the traversing chuck enters between the gripping portions of the closing chuck and is in parallel.

In the conventional apparatus, the receiving side chuck performs not only the receiving process but also the extending process. However, the transverse chuck of the present invention is in charge of only the receiving process. It is possible to perform the process and the extension process in parallel. The gripping part of the traverse chuck is also configured with a total of four clip forces. This is to allow the cloth to be delivered with both ends of the cloth stretched when delivering the cloth to the center chuck. It is. In addition, by providing a total of four clips, there is an effect that even when heavy cloth is moved left and right at high speed, it is less likely to be displaced.

[0012] The delivery device is located at the center of the machine frame and spreads the cloth held by the traverse chuck to the chuck, and includes a pair of arms pivotally attached to the machine frame, An inner center chuck and an outer center chuck provided at the tip, a pair of center chuck turning cylinders that move the arm to a position facing the transverse chuck, and a center force that opens and closes each center chuck. It consists of a chuck gripping cylinder and a center chuck extension cylinder that adjusts the degree of opening of the inner center chuck and the outer center chuck. The inner center chuck has a larger gripping claw than the outer center chuck.

When the outer center chuck spreads outward, the outer center chuck grips the corners of the cloth, and the both end corners of the cloth are stretched to a certain width from the inner center chuck. At this time, the gripping force of the outer center chuck should be weaker than that of the inner center chuck so that excessive force is not applied to the cloth. In order to reduce the driving force of the center chuck extension cylinder, it is preferable to make the gripping claws of the outer center chuck smaller than the inner center chuck.

In the present invention, when the input chuck → the transverse chuck → the center chuck → the spread chuck and the cloth are relayed, the gripping position gradually shifts inward. By gripping it, it is possible to extend the corner to the end of the cloth by passing the corner to the spreading chuck.

Further, by providing the delivery device, the traversing chuck can be moved to a position opposite to the other feeding device without waiting for the cloth spreading process to be completed.

[0013] The expansion device includes a spread chuck that is a pair of holding tools provided on a second rail arranged in the left-right direction of the machine frame, a spread chuck holding cylinder that opens and closes the spread chuck, and a spread chuck. It consists of left and right spreading chuck slide motors that move in the left-right direction. The left and right spreading chucks can be moved away from each other or in the proximity direction along the second rail by operating the spreading chuck slide motor in the forward or reverse direction. The upper end fixing bar is located at a height directly below the stretching device and facing the horizontal movement device, and has a gap through which cloths can pass at the center. Unfolding chuck force When the fabric is delivered to the horizontal moving body, the fabric is clamped by the upper end fixing bar and the horizontal moving body. The stretching device performs only a very simple operation when receiving and stretching the cloth, so that complicated operation control is unnecessary. In addition, it is possible to perform a cloth receiving process using a traverse chuck in parallel with the stretching process.

[0014] The intake device is provided below the expansion device, and has a vacuum bottom provided with a suction port at the top, an intake fan that sucks air in the vacuum box, and the front side in the vicinity of the suction port of the vacuum box ( And an infeed roller provided on the upper side of the front side wall. The feed roller is provided on the front side near the suction port of the vacuum box (upper front wall). When the upper edge of the cloth is fixed by the upper end fixing bar and the horizontal moving body, which are located directly below the spreading chuck and facing the horizontal moving body, the intake fan is activated, and the air is fed almost at the same time. When the feed roller is rotated at high speed in the feed direction by the roller motor, the lower part of the cloth is sucked into the vacuum box and spreads up and down.

In the present invention, since the upper side portion of the cloth is fixed at the time of suction by the vacuum box, it is possible to solve the problem that the stretched upper side portion hangs down due to suction and the shaping is lost.

[0015] The horizontal moving device includes a horizontal moving body that moves forward and backward to the upper end fixed bar above the transfer conveyor, a vacuum motor that applies a suction force to the suction box of the horizontal moving body, and a horizontal moving body that horizontally moves the horizontal moving body The cylinder is provided with a gap through which the cloth gripped by the center chuck can pass, and is composed of a left and right air blow provided adjacent to the upper end fixing bar. The horizontal moving body has a left and right length that is about the maximum width of the cloth to be processed, and a suction box with many small holes for suction is formed on the upper surface of the front end, which is moved horizontally by a vacuum motor. By sucking the air inside the body, the upper side of the cloth can be adsorbed on the upper surface of the horizontal moving body. Reduced state of horizontal moving cylinder Then, when the horizontal moving body spreads and is positioned near the bottom of the chuck and the cylinder extends, the horizontal moving body can move to the back side at a high speed.

Minimize the falling and slipping of the cloth during delivery by delivering air by blowing air from the air blow to the upper side of the cloth while the cloth is clamped by the top fixed bar and the horizontal moving body Can do.

[0016] The transport device is provided in front of the transfer conveyor, which is a perforated belt in which a large number of small holes are formed, and rotates more than the horizontal movement speed of the horizontal moving body and the rotation speed of the transfer compressor. It consists of a peeling shaft with a low speed, an intake passage provided below the transfer competitor, and a discharge compressor connected to the transfer competitor. The terminal end of the discharge competitor is continued to the input compressor on the press side.

The intake passage communicates with the vacuum box, and a suction force can be applied to either the vacuum box or the intake passage by a switching damper. During transport, a negative pressure is generated in the intake passage and the cloth supplied to the transport competitor is sucked and held to ensure the feeding of the cloth by the transport competitor.

By making the rotation speed of the peeling shaft slower than the moving speed of the horizontal moving body, when the fabric is transferred from the horizontal moving body to the transfer compressor, the friction between the horizontal moving body and the speed of the peeling shaft is sufficient. Since the force is generated, the upper side of the cloth can be smoothly peeled off and transferred to the transport device without turning over.

In addition, by making the rotation speed of the peeling shaft slower than the rotation speed of the transfer competitor, a weak frictional force works when transferring to the peeling shaft force transfer competitor, and the sheet is conveyed in a state of being properly stretched in the vertical direction. When wrinkles occur << high quality.

Furthermore, since it is not necessary to reduce the speed of the transfer competitor in order to secure the speed difference, the processing efficiency is improved.

The invention's effect

According to the present invention, by separating the receiving side chuck in the conventional apparatus into the transverse chuck and the spreading chuck, the receiving process by the transverse chuck and the extending process by the spreading chuck can be performed in parallel. Processing efficiency can be improved.

[0018] In the delivery device, by rotating the outer chuck outward, the corners of the cloth can be reliably secured. Since the part can be gripped, it can be extended to the end of the cloth.

By fixing the upper side of the fabric with the upper end fixing bar, there is no possibility that the upper side of the fabric will hang down due to suction and the shaping will be lost, and a high quality finish can always be obtained. In particular, a remarkable effect is exhibited when the target fabric is large and heavy.

Further, since the fabric is fixed by the upper end fixing bar, it is possible to eliminate the slippage of the fabric when the fabric is transferred from the stretching device to the horizontal movement device.

[0019] By providing the peeling shaft in front of the transfer conveyor, a sufficient speed difference between the horizontal moving body and the transfer conveyor can be secured, so that the upper side of the cloth when delivering the cloth to the horizontal moving body force transfer compensator Turn over of the part can be eliminated.

It shows the operation when pushed down, and the raising and lowering slide cylinder 2 raises the closing chuck 1 while holding the cloth a with the clip la˜: Ld. At this time, the traversing chuck 3 is moved horizontally by the traversing chuck slide motor 4 to a position facing the input chuck 1 that is in the ascending process, and stands by with the clips 3a to 3d opened. When the input chuck 1 is raised to the delivery position, the clips 3a and 3b are inserted between the clips la and lb, and the clip 3C 3d is inserted between the clips lc and Id. The clips la to ld are released by coming into contact with the plate 52, and the cloth 3 is held by the clips 3a to 3d by operating the opening / closing bar 51 by the transverse chuck opening / closing cylinder 29. When the delivery of the fabric a is completed, the feeding chuck 1 starts to descend, and a little later, the traverse chuck 3 starts moving horizontally toward the center of the machine frame. FIG. 4 shows an operation when the fabric a is delivered from the transverse chuck 3 to the delivery device 200. When the traverse chuck 3 holding the cloth a moves to the center of the machine frame, the center chuck 5 and 6 are rotated forward by the center chuck turning cylinder 7, and the center chuck 5 and 6b are clamped between the clamps 3a and 3b and 3c and 3d. When the 6 gripping claws are positioned, the center chuck gripping cylinder 20 operates to grip the cloth, and the gripping portion of the traverse chuck 3 is operated by the traverse chuck opening / closing cylinder 29. The cloth a is transferred from the traverse chuck 3 to the center chucks 5 and 6 by being released by. When the delivery of the fabric a is completed, the center chucks 5 and 6 are returned to the original swiveling position by the center chuck rotating cylinder 7.

After the delivery, the transverse chuck 3 waits at the center of the machine frame until the next cloth starts to rise.

FIG. 5 shows an operation of a pre-process for delivering the fabric a from the delivery device 200 to the spreading device 300. The center chuck extension cylinder 27 causes the outer center chucks 6 to spread outward so that the corners of the fabric a are stretched several centimeters. At this time, since the gripping force of the outer center chuck 6 is weaker and the gripping claws are smaller than those of the inner center chuck 5, both end corners are stretched while sliding. Thereafter, the center chucks 5 and 6 are further swung backward by the center chuck turning cylinder 7, and the both end corners of the cloth a are spread and held by the chuck 8, and the cloth is delivered. When the delivery of the fabric a is completed, the center chucks 5 and 6 are returned to the original turning position by the center chuck turning cylinder 7.

Separately, the transverse chuck 3 that has detected the rising signal of the input chuck 1 that holds the cloth b moves to the opposite position.

FIGS. 6 and 7 show an operation when the fabric a is stretched in the left-right direction by the stretching device 300. The spread chuck 8 that has received the cloth a is spread by the spread chuck slide motor 9 in synchronism with each other and left and right to expand the cloth a in the left-right direction. The horizontal moving body 11 starts to move forward by the horizontal moving body cylinder 32.

Separately, the transverse chuck 3 receives the cloth b from the input chuck 1 and moves horizontally to the center of the machine frame.

FIGS. 8 and 9 show the operation when the fabric a is stretched in the vertical direction from the stretching device 300 and delivered to the horizontal moving body 11. After the fabric a is completely spread, the fabric a When sandwiched between the front end and the upper end fixing bar 12, the feed roller 33 rotates at a high speed, and the switching damper 15 is switched, and the suction force by the vacuum box 24 works and is suspended by the wide chuck 8. The cloth a is sucked into the vacuum box 24 and is spread by the downward flow of air and its own weight. After that, the switching damper 15 is switched again, the suction force by the vacuum box 24 is stopped, air is blown from the air blow 14 toward the upper side of the cloth a, the chuck 8 is opened, and the suction force is activated by the vacuum motor 17. The upper side of the cloth a is transferred onto the suction box 31 of the horizontal moving body 11. Separately, the cloth b is delivered from the transverse chuck 3 to the delivery device 200. The center chucks 5 and 6 that have received the cloth b are returned to the original turning position by the center chuck turning cylinder 7 and wait until the chuck 8 is opened.

FIGS. 10 and 11 show the operation when the fabric a is transferred from the horizontal moving body 11 to the transport device 600. When the horizontal moving body 11 moves further rearward by the horizontal moving body cylinder 32, the cloth a first comes into contact with the peeling shaft 19. Since the rotation speed of the peeling shaft 19 is sufficiently slower than the horizontal moving body 11, the frictional force works, and further, the horizontal moving body 11 moves backward to increase the frictional force. Is out of the suction box 31 force. At this time, since the switching damper 15 is already switched, the suction force by the intake fan 16 is acting on the intake passage 25, and the suction action of the intake passage 25 and the natural fall due to the own weight of the cloth a. Therefore, it is placed on the upper surface of the transfer competitor 18. Thereafter, by the rotation of the transfer compressor 18, the fabric a is transported to the discharge compressor 34, and then continuously transported to the input compressor (not shown) on the press machine side.

Separately, the fabric b is transferred from the center chucks 5 and 6 to the stretching device 300, and the stretching process of the fabric b by the stretching device 300 is performed.
