Description

Tumbler device {TUMBLER APPARATUS}

In particular, the present invention relates to a tumbler apparatus, in particular, a tumbler apparatus in which the structure of a ladder in which a fabric is laminated is improved to minimize the influence of wind, thereby enabling the total weight of the fabric and the ladder to be accurately measured by a tensile load measuring method, , The guide structure for guiding the falling direction of the fabric by guiding the direction of the wind before being loaded on the right stacking bed is provided to smoothly stack the fabric on the stacking table and to easily remove the foreign matter on the surface of the fabric The present invention relates to a tumbler device having an improved structure.

Generally, ordinary textile fabric is contaminated with fine dust and chemical immediately after production, and the dyed textile fabric is used for prevention of water dropout and for clothing. In order to prevent deformation of fabric due to washing or heat, Wash it.

Therefore, when a large amount of fiber fabric that has been drenched with water by washing is required to be quickly dried at a time, the dryer is often used because natural drying is limited in place and time.

A conventional textile fabric dryer comprises a feed roller for feeding a laid fiber fabric, a drying section for drying the fiber fabric, and a feed roller for feeding the fiber fabric passed through the drying section to the chamber at the next stage, And a plurality of chambers are connected to form a single chamber to dry the fabric.

However, in the above-mentioned textile fabric dryer, the process of transferring the fiber cloth from the lower part of the fiber cloth accumulated in the process of transferring between the chamber and the chamber is repeated, so that the fiber cloth is stretched due to the load. There is a problem in that heat loss is generated as the fiber fabric is discharged to the outside and is not effectively dried.

As a prior art of a conventional textile fabric dryer for improving this, there has been proposed a method of drying a laundered textile fabric by hot air drying, as disclosed in Korean Patent Registration No. 10-1161176, entitled " Textile Fabric Dryer " In the textile fabric dryer, there is provided a drying unit for drying and touching the fiber fabric conveyed in the longitudinal direction with hot air, wherein a plurality of drying units are installed in the upper part of the dryer chamber, and the drying unit includes hot air circulating through the space communicated with the combustion unit And the hot air supplied to the left and right spray nozzles is controlled by the hot air opening / closing means, and the inside of the dryer chamber The second loading section and the third loading section for loading the fiber fabric are disposed at the lower part of the left and right spraying nozzles, To ensure that the fiber fabric is configured to be loaded fiber fabric is transferred to the rear drying.

In this case, since the left and right spray nozzles are required to narrow the width of the hot air toward the end so as to compressively inject the hot air into the passage of the dust transfer section, the structure for supplying the hot air to the fiber fabric is complicated, There is a possibility that the transfer becomes impossible.

Another prior art related to a conventional textile fabric dryer is a fabric processing apparatus in which a fabric is inserted and processed as disclosed in Korean Patent Registration No. 10-1333086 entitled " Fabric Processing Apparatus "(Registered Date: Nov. 20, 2013) A pretreatment unit for pretreating and receiving a fabric wound on a roll, and a processing unit for processing the fabric processed by the pretreatment unit, wherein the pretreatment unit comprises: a netting unit for immersing and padding the fabric in the treatment liquid; And a pre-drying unit for drying the supplied fabric, wherein the processing unit includes a raw material input unit into which the raw material is inserted, a raw material discharge unit through which the raw material is discharged, a hot air unit in which the external fluid is heated and heated, A plurality of processing units including a raw material retaining portion in which a raw fabric is processed by using a fluid, the raw fabric being processed in an emulsion state; At least one or more scattering parts for physically deflecting the fabric processed in the processing part; And a foreign matter collecting part for collecting foreign matter such as dust generated in the processing part, wherein the raw material input part is attached to one side face of the far-end retention part, and serves as a passage through which the raw fabric can be smoothly inserted, And a weft weighing device positioned at a lower portion of the upper raw material feeding portion and positioned at a lower feeding portion where the raw material is stacked and a lower end of the lower feeding portion. The raw material discharging portion is attached to the other side of the far- And a weft weighing device positioned at a lower portion of the upper far end discharging portion and positioned at a lower portion of the lower discharging portion in which the fabric is stacked.

In the above case, the raw material input unit and the raw material discharge unit are disposed at the lower part thereof, and the weight of the raw material is sensed by a load cell method that detects the weight of the raw material using the pressing force that is applied from the upper side. However, It is difficult to accurately measure the weight of the fabric when it is moved upward or downward or moved due to the influence of the jetting force.

In addition, in the above-described conventional embodiments, since the hot air is blown to the side where the fabric is laminated, vibration is generated in the fabric laminating area due to the influence of hot air, so that vibration noise is generated, The fabric is not smoothly laminated and the foreign matter on the surface of the fabric is not easily removed.

Further, in the case of a rotating blade type damper structure for selectively supplying hot air to the left and right injection nozzles, there is a disadvantage in that the structure is complicated and quick opening and closing operations can not be switched.

Korean Patent Registration No. 10-1161176 entitled "Textile Fabric Dryer" (registered on June 25, 2012) Korean Patent Registration No. 10-1333086 "Fabric Processing Apparatus" (Registered on Feb. 20, 2013)
