Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a pre-treatment device for treating cloth to be passed through an ironer after washing and dehydration.

(Prior Art) Among all types of cloth, the bag-like part of the periphery of a wrapping cloth such as a futon cover turns inside out when it is removed from the futon, and the rate of this is over 90%. This is something that happens when work is done quickly.
Since the condition does not change even after washing and dehydrating, it is necessary to turn the item inside out and put it back to its original state.

Furthermore, if air accumulates in the bag-shaped portion of the futon cover, it will wrinkle when ironed and lose its commercial value, so it is necessary to remove these wrinkles and make it flat. The work of restoring and flattening the bag-shaped part that has been turned inside out has traditionally been done by manpower, consuming a great deal of time and effort, and there are no working machines known that can handle it automatically. do not have.

As a result of research and development, the inventors of the present invention have developed a method for turning the bag-like portion inside out to return it to its normal state, and a device for carrying out the method. The present invention implements a method of drying and ironing the clothes using a roll ironer after washing and dehydration, and is most suitable as a pretreatment for passing cloth such as the above-mentioned wrapping cloth through an ironer. However, it is clear that the invention is not limited to wrappings, but can be applied to a wide range of fabrics in general.

(Technical Problem) That is, the object of the present invention is to provide a device that can fold cloth while transporting it and stack it up for sending to an ironer, and that can process even undried cloth after dehydration without any problem. An object of the present invention is to provide a fabric pretreatment device that can perform the following steps.

(Technical Means) The present invention that achieves the above object includes a feeding conveyor installed in the main body of the device so as to rotate in a fixed direction for conveying cloth, and a required interval below the feeding end of the feeding conveyor. The stacking conveyor is arranged approximately parallel to the feed conveyor and alternately rotates forward and reverse in the direction of rotation of the feed conveyor to fold the cloth. This is a fabric pre-treatment device equipped with an elevating mechanism that lowers the fabric and returns it to its original position.

(Operation of the Invention) Mechanically, the present invention can be said to be constituted by a feed conveyor and a stacking conveyor that is disposed below the discharge end of the conveyor and is capable of descending. To explain according to the embodiment, the cloth C is transported by the feeding conveyor 20.
is supplied onto the stacking conveyor 2 by
The stacking conveyor 2 alternately repeats normal rotation and reverse rotation to perform folding according to the number of rotations. By one reverse rotation, that is, forward rotation, the fabric can be pulled out almost half way onto the stacking conveyor, and then by reverse rotation, it can be folded in half, and once and a half in forward and reverse rotation.
In other words, by rotating forward, reverse, and forward along a line that is one-third of the length of the cloth, you can fold it into three (Figure 3 a~
c). For convenience, forward rotation refers to the rotating direction of the stacking conveyor 2 in the same direction as the rotating direction of the feed conveyor 20, but the bifolding and trifolding may also start from the reverse rotation. Before folding the next cloth, the stacking conveyor descends to a height that allows the stacked folded cloths to pass through without colliding with the feeding conveyor, and this process is repeated to sequentially stack the folded cloths.

(Example) The following will be explained with reference to the illustrated example. In each figure, 1
2 is the main body of the device, 2 is a stacking conveyor installed approximately horizontally in the middle of the stacking conveyor, and the conveyor 2 consists of a large number of belts 5 wound around between front and rear rolls 3 and 4, and chain sprockets and other connections. The means 6 is driven by a motor 7 to rotate in forward and reverse directions. Note that the direction in which the upper surface of the belt faces from roll 3 to roll 4 is normal rotation. 8, 8 is a member having a substantially U-shaped cross section that serves as a guide for vertical movement of the stacking conveyor 2; 9 is a bearing provided in the vertical direction of the guide member 8;
10 is a belt support; 11 is a lifting mechanism for lowering the stacking conveyor 2 as a whole at intervals d corresponding to the folded thickness of the fabric and returning it to the original position shown in FIG. 2; A hydro converter 11' is used.

20 is a feeding conveyor, when the stacking conveyor 2 is at the original position, that is, at the top, the conveyor 2
The inclined part 2 is installed in the main body 1 so that the discharge end of the cloth C is located at the upper position with a required distance d, and the inclined part 2 is installed in the main body 1 so that the discharge end of the cloth
1 on the unloading end side, and further has an inclined part 22 on the front side for carrying in the cloth C, and the roll 2 is formed in a generally chevron-shaped or angular shape as a whole.
3, 24 and rolls 26, 27 for providing a protrusion 25 in the center, and is driven by a motor 29 through a chain sprocket or other connecting means 28, and a belt 30 similar to the stacking conveyor 2.
It has many. 31 is a sensor, and the rear inclined part 21
The lifting mechanism 1 detects the fabric C and sends a signal to rotate the stacking conveyor 2 in the normal direction.
Send to 1. In addition, stacking conveyor 2 of the example
is rotated at a slightly faster speed than the feed conveyor 20, and the fabric is slightly stretched to prevent wrinkles from forming.

Furthermore, in the apparatus of this embodiment, a device 40 for reversing a wrapping cloth C', which is one type of cloth C, is provided in front of the feeding conveyor 20. 42A and 42B are claws for holding the wrapping cloth C', 43 is an expansion mechanism installed at the upper front of the opening mechanism, 44 is a blower, 45A and 45B are nozzles connected thereto, 46A and 46B are installed at the lower front of the main body, An expanding belt with protrusions on the surface that moves left and right in front of the bag.
The lower part of C' protrudes slightly in front of the claw 42 so that it touches and spreads to the left and right (see Figure 3a).

The claws 42A, 42B have a detector 47 such as a photoelectric switch for detecting the approach of the wrapping cloth C', and an air cylinder 48 for opening/closing. installed on. The expansion mechanism 43 is composed of the rodless cylinders 51, 52 which are power sources, and a circumferential cable 55 which fixes the movable members 53, 54 and defines the amount of movement thereof. The circumferential cable 55 is a clamp 56
By connecting the left and right movers 53, 54 and moving left and right between the pulleys 57, 58, the claws 42A, 4
2B is configured so that it can move equally from the center to the left and right.

The nozzles 45A and 45B are provided at the tips of ducts 61 and 62 whose ends are connected to the blower 44, and are provided diagonally above the main body so as to intersect from the left and right in front of the wrapping cloth. This means that in order to invert the lower corners c ₃ , c ₄ far from the center of the wrapping cloth C′ beyond the edges e ₃ , e ₄ , approximately extensions of both parts c ₃ , e ₃ and c ₄ , e ₄ are required. This is the result of finding that spraying from any direction is effective. The cross mark indicates the point at which air should be blown, and it is best to slightly inside the edges e ₃ and e ₄ .

The claws 42A, 42B can be moved in the direction of the feed conveyor 20 by the reciprocating mechanism 60 (arrow in FIG. 3A), thereby performing the inversion of the wrapping C' and subsequent folding and stacking. The parts are connected, and the wrapping cloth C' is delivered.

Therefore, taking the wrapping cloth C' processing as an example, after washing and dehydration, the wrapping cloth C' corners c ₁ and c ₂ are turned over and the nails 42
A, 42B, and after expanding the nozzle 45A,
45B, the lower side is turned inside out, and when this is completed, the claws 42A and 42B move back according to the operation command, and when it passes over the protrusion 25 of the feed conveyor 20, the wrapping C' is released, and the tip of the wrapping C' reaches the sensor. When the stacking conveyor 2 is detected at 31, it starts rotating in the normal direction, carries the wrapping cloth C' by a predetermined length in the normal direction, and then reverses, thereby folding it into two, three, etc. , after the end of the wrapping passes, the conveyor 2 stops and descends by a predetermined distance d. This process is repeated and the piled up wrappings are transferred to the next process such as ironing. Note that in order to prevent the tip of the cloth from bending, the claw 42 must be
It is preferable to open A and 42B and pass them to the rotating conveyor 20.

(Effects of the Invention) Since the present invention is constructed and operates as described above, by rotating the stacking conveyor forward and backward while feeding the cloth by the feed conveyor, the cloth can be folded and folded. , it has the effect of being able to stack the fabrics one after another, and by switching between forward and reverse rotation of the stacking conveyor at one-half or one-quarter of the length of the fabrics. You can easily fold it in half or in three. In addition, by forming the feed conveyor in a chevron shape, it is expected that the resistance of the chevron-shaped protrusion will prevent the fed cloth from rebounding and forming wrinkles due to reaction, and furthermore, the tip of the cloth will hang down by the required distance at the discharge end of the feed conveyor. It has the characteristic that wrinkles do not occur at the tip.
