Description

Continuous drum device equipped with buffer zone

Technical Field

The present invention relates to a continuous drum device equipped with a buffer zone, and more particularly, to a continuous drum device equipped with a buffer zone having an improved structure, which can improve the texture of a cloth and prevent foreign materials in a chamber from being attached to the cloth, can improve the drying efficiency of the fiber cloth, and can minimize the occurrence of undesirable phenomena such as wrinkles during the transfer of the cloth by concentrating an air discharge portion of the buffer zone to the center by providing a buffer zone capable of discharging a pressure generated from a nozzle to the upper and lower sides in the buffer zone between a nozzle zone and a nozzle zone of a drum device, thereby forming the movement of the transferred cloth in a wave pattern by means of the pressure and thereby delaying the transfer of the cloth.

Background

In general, fiber cloth is in a state of being contaminated with fine dust, chemicals, and the like immediately after production, and thus, it is necessary to perform pre-washing, particularly, dyed fiber cloth in order to prevent discoloration and fiber cloth used for manufacturing clothes in order to prevent deformation of the cloth after being washed with water and when being heated.

When a large amount of fiber cloth containing moisture due to washing needs to be dried simultaneously and rapidly, a dryer is generally used because natural drying is limited in place and time.

Existing fiber cloth dryers include: a supply roller for transferring the washed fiber cloth; a drying part for drying the fiber cloth; and a transfer roller for transferring the fiber cloth passing through the drying part to the side end chamber; wherein the above-mentioned components constitute one chamber and a plurality of interconnected chambers are intended for drying the fibre cloth.

However, since the above-described fiber cloth drying machine repeats the process of transferring the fiber cloth from the lower portion of the stacked fiber cloth while transferring the fiber cloth between the chambers, the fiber cloth is stretched by a load, and the fiber cloth needs to be transferred by exposing the fiber cloth to the outside by the rollers while transferring the fiber cloth between the chambers, thereby failing to efficiently dry the fiber cloth due to heat loss.

As a prior art of a conventional fiber cloth dryer for improving the above problems, korean registered patent publication No. 10-1161176, entitled "fiber cloth dryer" (registration date: 2012.06.25), discloses a fiber cloth dryer for drying a washed fiber cloth with hot air, comprising a drying part for drying and touching a fiber cloth transferred in a longitudinal direction with hot air, a plurality of right and left spray nozzles installed at an upper part of a dryer chamber, the drying part comprising a duct for injecting hot air circulating through a space part communicating with a combustion part into a cloth transfer part and transferring the fiber cloth passing through the duct in a right and left direction, the hot air supplied to the right and left spray nozzles being restricted by a hot air opening/closing part, a 2 nd loading part and a 3 rd loading part for loading the fiber cloth under the nozzles being installed in the dryer chamber, the 3 rd loading part loads the fiber cloth to the inclined part of the tail part of the rear end, so that the fiber cloth is transferred to the rear drying part.

In the case of the above, in order to inject hot air into the side of the duct of the cloth transfer part by compression, it is necessary to provide left and right injection nozzles whose width is gradually narrowed toward the end portions, so that the structure for supplying hot air to the fiber cloth becomes more complicated, and there is a possibility that the cloth cannot be normally transferred because the cloth is blocked by the end portions of the left and right injection nozzles.

As another prior art relating to a conventional fiber cloth dryer, korean laid-open patent publication No. 10-2012-0051214 "cloth continuous drum processing apparatus" (published: 2012.05.22) discloses a novel cloth continuous drum processing apparatus which performs processing by using a cloth input part, a cloth processing and heat treatment part, a cooling part, a finishing member and a control member part in order to deform and process the pile formed on the upper side of a pile fabric cloth, thereby improving the thermal efficiency of the heat treatment part used in the processing of the cloth and saving the heat treatment cost, and eliminating the entanglement or kink of the cloth, and also eliminating the post-processing process occurring in the cloth processing by improving the processing speed and the processing efficiency of the cloth.

Further, as another prior art related to the conventional drum device, a drum device is disclosed in korean registered patent publication No. 10-1758243, "drum device" (registration date: 2017.07.01), which is characterized by comprising: a housing for transferring the fiber cloth from the outside to the inside; a hot air supply part which is configured in the shell and forms a transfer channel of the fiber cloth by forming an opening part at the left and right sides; 1 st, 2 nd, 3 rd and 4 th spray nozzles respectively arranged at the upper and lower sides of the hot air supply part and arranged at the left and right sides of the hot air supply part in a manner that hot air spray angles are opposite to each other; an upper and lower hot air injection pipe for supplying hot air to the 1 st, 2 nd, 3 th and 4 th injection nozzles; a damper part disposed inside the hot air supply pipe for alternately supplying hot air to the upper and lower hot air injection pipes; a guide member disposed at both left and right sides of the hot air supply part at an interval for guiding a falling direction of the fiber cloth discharged from the hot air supply part; and a loading table disposed below the guide member for loading the fiber cloth dropped by the guide member; wherein a plurality of through holes whose width is gradually reduced toward the hot air supply direction are formed on the surfaces of the upper and lower hot air injection pipes facing each other so as to communicate with the injection nozzles 1, 2, 3, and 4.

However, in the conventional continuous drum device, the fiber cloth is transferred between the hot air supply portions adjacent to each other by the single tension roller and the guide roller while passing through the chambers, which may cause a decrease in drying efficiency of the fiber cloth and a possibility of adhesion of foreign substances floating in the chambers.

Detailed Description

The invention provides a continuous drum device for drying and arranging fiber cloth, which is provided with a buffer area for delaying the transfer process of the fiber cloth between a nozzle area and a nozzle area.

Next, a continuous drum apparatus equipped with a buffer zone to which the present invention is applied will be described in more detail by way of an embodiment which will be described in detail with reference to the accompanying drawings.

In describing the present invention, when it is determined that detailed description on related known techniques or configurations may cause the gist of the present invention to become unclear, detailed description thereof will be omitted. In addition, terms used later are only terms defined in consideration of functions in the present invention, and may be changed according to user's intention, convention, or the like. Therefore, it should be defined based on the entire contents in the present specification. Further, when it is described that a certain constituent element is "included", unless otherwise explicitly stated to the contrary, it is not meant to exclude other constituent elements, but it should be understood that other constituent elements can be also included.

An embodiment of a continuous drum apparatus equipped with a buffer zone to which the present invention is applied is shown in fig. 1 to 4, and includes: a housing 10 for transferring a fiber cloth 30 from the outside to the inside, and having a plurality of chambers 20 therein; a hot air supply part 200 disposed inside the housing 10 and constituting a transfer path of the fiber cloth 30; a plurality of nozzle blocks 100 disposed inside the respective chambers 20 and disposed above and below the hot air supply unit 200, respectively, and including spray nozzles 110 for spraying hot air to transfer the fiber cloth 30 in one or the other direction; and a buffer area 300 disposed between the nozzle areas 100 and having a discharge port 325 for discharging the hot air discharged from the spray nozzle 110 upward and downward.

Referring to fig. 1, the housing 10 is formed by continuously arranging the chambers 20 and forms a passage through which the fiber cloth 30 is transferred.

The nozzle regions 100 are provided in the respective chambers 20 and are provided with the spray nozzles 110 at upper and lower sides in a symmetrical structure with each other.

The hot air supply unit 200 is configured such that the nozzle blocks 100 are connected to the buffer block 300, so that the fiber cloth 30 can be transferred through the chambers 20.

As shown in fig. 2, the nozzle block 100 includes a plurality of injection nozzles 110 in each nozzle block 100: 1 st and 2 nd nozzles 110-1 and 110-2 arranged in 2 rows for jetting hot air so as to transfer the fiber cloth 30 from one side to the other side; and 3 rd and 4 th spray nozzles 110-3 and 110-4 arranged in 2 rows at positions spaced apart from the 1 st and 2 nd spray nozzles 110-1 and 110-2, and spraying hot air so that the fiber cloth 30 can be transferred from the other side to the one side.

The nozzle block 100 transfers the fiber cloth 30 from one side to the other side and loads the fiber cloth 30 on the loading table 80 provided on the other side when the hot wind is injected from the respective 1 st and 2 nd injection nozzles 110-1 and 110-2, and transfers the fiber cloth 30 from the other side to one side and loads the fiber cloth 30 on the loading table 80 provided on one side when the hot wind is injected from the respective 3 rd and 4 th injection nozzles 110-3 and 110-4.

The nozzle block 100 is configured such that the spray nozzles 110 are symmetrically arranged on the upper and lower sides of the hot air supply unit 200 and are formed at an angle inclined with respect to the transfer direction of the fiber cloth 30.

Upper and lower hot

air injection pipes

60 and 70 for supplying hot air to the injection nozzle 110 are provided at upper and lower sides of the hot air supply unit 200.

As shown in fig. 1 and 3, the buffer 300 includes: a buffer housing 310 which is connected to the hot air supply part 200 of the adjacent chamber 20 and communicates with the inside of the chamber 20; and upper and

lower buffer plates

320A and 320B disposed in a symmetrical manner to each other on upper and lower sides in the buffer housing 310 and having a plurality of discharge ports 325 for discharging the hot air discharged from the spray nozzle 110.

The buffer cover 310 connects the hot air supply units 200 of the adjacent chambers 20 so that the adjacent chambers 20 can be connected to each other, and forms a transfer path in which the fiber cloth 30 can be transferred.

The upper and

lower baffle plates

320A and 320B have discharge ports 325 formed in the center portions thereof excluding the left and right sides thereof, and have closed spaces 322 formed on the left and right sides thereof in which the discharge ports 325 are not formed.

The discharge ports 325 are formed in a plurality of rows in the center of the upper and

lower buffer plates

320A and 320B, and the length L2 of 1 row of the spray nozzles 110 is longer than the length L1 of 1 row in which the discharge ports 325 are formed.

The length L1 of the 1 row forming the discharge opening 325 and the length L2 of the 1 row of the spray nozzle 110 are formed in a length ratio of 0.6-0.88: 1.0.

If the length ratio of L1 to L2 is less than 0.6, the pressure difference between the central portion and the left and right side portions of the upper and

lower cushion plates

320A and 320B becomes excessively large, which may cause a problem of wrinkles being formed on the surface of the fabric 30 during the transfer of the fabric 30, and if the length ratio of L1 to L2 exceeds 0.88, a problem of oblique movement or inclination may be caused during the transfer of the fabric 30.

The height interval between the upper and

lower buffer plates

320A and 320B is preferably 40 to 65mm, and when the height interval between the upper and

lower buffer plates

320A and 320B is less than 40mm, a problem may occur that the cloth 30 is lumped and falls down during the transfer of the thick cloth 30, and when the height interval between the upper and

lower buffer plates

320A and 320B exceeds 65mm, a problem may occur that the cloth 30 moves obliquely from the center to the left and right sides or inclines to one side during the transfer of the thin cloth 30.

The cross-sectional area of the entire injection nozzle 110 and the cross-sectional area of the entire discharge port 325 formed by the perforations of the upper and

lower buffer plates

320A, 320B are preferably set to a ratio of 1.0:1.05 to 1.2.

By maintaining the ratio of the entire cross-sectional area of the discharge port 325 to the entire cross-sectional area of the injection nozzle 110 at 1.05 to 1.2, the back pressure (back pressure) of the hot air can be stably maintained so as not to change excessively.

In the present invention configured as described above, the fiber cloth 30 transferred from one side to the other side or from the other side to the one side along the hot air jetting direction of the jetting nozzles 110 of the nozzle block 100 can be dried by hot air in the continuous drum device in which the chambers 20 are continuously arranged.

At this time, the fiber cloth 30 passes through the buffer area 300 after being transferred by the hot air supply unit 200 in the chamber 20 and before being transferred to the hot air supply unit 200 side of the other adjacent chamber 20, and the hot air pressure sprayed from the spray nozzles 110 of the nozzle area 100 and supplied into the buffer housing 310 is discharged from the interior of the buffer housing 310 into the chamber 20 through the discharge ports 325 formed in the upper and

lower buffer plates

320A and 320B while the fiber cloth 30 passes through the buffer area 300.

After the hot air jetted from the jet nozzle 110 flows into the inside of the buffer housing 310 of the buffer area 300, since the jetting ports 325 are not formed on both the left and right sides of the upper and

lower buffer plates

320A and 320B, the pressure of the hot air is not jetted therefrom and thus the pressure is maintained on both the left and right sides of the upper and

lower buffer plates

320A and 320B, but on the contrary, the jetting suction force is transmitted to the side of the conveyed planar fiber cloth 30 by the jet nozzle 110 and changed into the wave form in the central portion where the jetting ports 325 are formed in the process of jetting the hot air through the jetting ports 325, and the conveyance of the fiber cloth 30 in the buffer area 300 is delayed with respect to the nozzle area 100.

Part of the hot air discharged through the discharge port 325 of the buffer 300 is recirculated through the filter 40 and the burner 50 in the chamber 20, and the remaining part is discharged to the atmosphere.

At this time, the fiber cloth 30 transfers the fiber cloth 30 from one side to the other side when the hot wind is sprayed from the 1 st and 2 nd spray nozzles 110-1 and 110-2, and loads the fiber cloth 30 on the loading table 80 provided on the other side in a multi-turn manner after passing through the respective chambers 20 and the buffer 300, and then transfers the fiber cloth 30 from the other side to one side when the hot wind is sprayed from the 3 rd and 4 th spray nozzles 110-3 and 110-4, and loads the fiber cloth 30 on the loading table 80 provided on one side in a multi-turn manner after passing through the respective chambers 20 and the buffer 300 again.

The fiber cloth 30 can be dried and arranged by the hot air injected from the injection nozzle 110 while being transferred from one side to the other side or from the other side to one side in a state of containing moisture, and the hot air can be discharged into the chamber 20 through the discharge port 325 and form a discharge pressure while passing through the buffer area 300, and at this time, the fiber cloth 30 passing through the central portions of the upper and

lower buffer plates

320A and 320B is transferred in a wave-like form by canceling the thrust force generated from the injection nozzle 110 at the discharge port 325 side, so that the transfer speed of the fiber cloth 30 passing through the buffer area 300 is delayed from the transfer speed passing through the nozzle area 100.

Therefore, the present invention can prevent foreign matters in the chambers from adhering to the fiber cloth being transferred by connecting the hot air supply parts 200 of the chambers 20 to the buffer covers 310 of the buffer areas 300 in the continuous drum device in which the respective chambers 20 are continuously arranged, and can also remove a part of thrust applied to the fiber cloth 30 by discharging a part of hot air pressure supplied from the jet nozzles 110 into the buffer covers 310 through the discharge ports 325 formed in the upper and lower buffer plates 320A, 320B of the buffer areas 300, blow the surface of the fiber cloth with strong hot air in a tension-free state of the fiber cloth 30, and transfer the fiber cloth in a bellows form by strong vibration generated in a process in which the pressure is discharged through the discharge ports 325 on the upper and lower sides while passing through the buffer areas 300, thereby achieving the water Shrinkage (Shrinkage) and the hot air supply parts 200 of the chambers 20 in the continuous drum device in which the respective chambers 20 are continuously arranged The touch performance of the fiber cloth is improved in the aspects of silky touch, softness, pile removal, raised pile removal, anti-clumping, wrinkle prevention, and the like, and the time for drying the fiber cloth 30 can be increased by delayed transfer of the fiber cloth 30, thereby improving the drying efficiency of the fiber cloth 30.

In addition, the present invention can prevent the fiber cloth 30 from moving obliquely or inclining while the fiber cloth 30 passes through the buffer cover 310 and is transferred to the hot air supply portion 200 side of the other adjacent chamber 20 by providing the closed space 322 on both the left and right sides of the upper and

lower buffer plates

320A and 320B, in which the discharge port 325 is not formed, so that the pressure acting on the closed space 322 is relatively greater than that of the central portion.

In addition, the present invention can prevent the fiber cloth 30 from being moved obliquely or inclined, that is, the bad transfer phenomenon of the fiber cloth 30, when the fiber cloth 30 is transferred in the buffer cover 310 by forming the interval between the length of 1 line of the discharge port 325 formed in the upper and

lower buffer plates

320A, 320B and the length of 1 line L2 of the spray nozzle 110 at a length ratio of 0.6 to 0.88:1.0 and by forming the height interval between the upper and

lower buffer plates

320A, 320B to be 45 to 65 mm.

Fig. 5 and 6 are schematic views illustrating another embodiment to which the present invention is applied, and as shown in the drawings, the buffer housing 310 further includes: an opening/closing unit 400 which is attached to the upper side of the left and right side closed sections 322 where the discharge port 325 is not formed, and selectively opens and closes the discharge port 325; wherein, the opening and closing part 400 comprises: a driving motor 410 driven by an external signal; and an opening/closing plate 420 that slides to the left and right when the driving motor 410 is driven by a driving shaft 412 coupled to the driving motor 410, and opens and closes a part of the discharge port 325.

Although not shown, the opening/closing unit 400 is provided with a guide rail for guiding the sliding operation of the opening/closing plate 420.

The opening/closing plate 420 is provided inside the buffer housing 310, and can open and close a part of the discharge port 325 of the upper and

lower buffer plates

320A and 320B.

Thus, according to another embodiment of the present invention, the number of openings of the discharge port 325 can be arbitrarily adjusted by the opening/closing unit 400 according to the input conditions and information of the fiber cloth 30 passing through the buffer cover 310, and the drying efficiency of any type of cloth 30 can be improved.

As described above, the specific examples are described in the detailed description of the present invention, but various modifications can be made thereto within a scope not departing from the scope of the present invention. Accordingly, the scope of the present invention should not be limited to the embodiments described in the above, but should be defined by the claims to be described later and the scope equivalent to the claims.

That is, the present invention described in the above-mentioned contents is not limited to the above-mentioned specific preferred embodiments, and various modifications can be made by those having ordinary knowledge in the art to which the present invention pertains within a scope not departing from the gist of the present invention claimed in the claims, and the modifications described above are included in the scope of the claims.
