Abstract

(57) [Summary] [Objective] A long web fed on a conveyor in a tension-free state was transferred integrally with the conveyor while preventing free movement on the conveyor, which made processing advantageous. [Structure] A web a is placed in a tension-free state on a net-shaped belt-like conveyor 1 having air permeability on the front and back sides, and is connected to the intake side of a blower 4 on the lower surface of the conveyor part of the conveyor 1 on which the web a is placed. Both of them have one or more suction nozzles 3 facing each other, and the suction operation of the suction nozzles 3 attracts the web a to the surface of the conveyor 1 through the air permeable conveyor to transfer the web a integrally with the conveyor 1 in a tensionless state.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an apparatus for safely transporting a woven fabric, a knitted fabric, a non-woven fabric, and other strip-shaped webs without tension.

[0002]

[Prior Art]

 When a long web such as cloth is dried, heat-treated or otherwise processed in a predetermined processing chamber, the processing web is placed on an endless traveling belt conveyor and conveyed in the processing chamber in a tensionless state. It is already well known to process such a process.

[0003]

[Problems to be solved by the device]

 In the web conveyance by the above-mentioned known conventional means, the web placed in a tensionless state on the belt-shaped conveyor is not constrained, so that the web meanders under the influence of the hot air velocity in the treatment chamber during the drying process, for example. However, there were many problems such as wrinkles, wrinkles, warping due to heating, slipping between the conveyor surface and damage to the web, and uneven rubbing due to rubbing.

[0004]

[Means for Solving the Problems]

 In view of the above, the present invention is intended to eliminate the above-mentioned conventional inconveniences and to safely and reliably convey a web placed on a conveyor in a tensionless state, and a belt-shaped conveyor made of a breathable material. In the case where the processing web is placed in a tension-free state and is conveyed in the processing chamber, at least one suction nozzle communicating with the intake side of the blower is installed so as to face the lower surface of the conveyor surface on which the processing web is placed. It is characterized by having done.

[0005]

[Action]

 As shown in the drawings of the embodiments, the apparatus for transporting a processing web according to the present invention, when the processing web a is placed on the front and back air-permeable belt-shaped conveyors 1 in a tensionless state and is transported in the processing chamber 2, The one or more suction nozzles 3 which are installed so as to open toward the lower surface of the air permeable conveyor 1 on which the web a is placed are moved downward through the air permeable conveyor 1 through the air permeable conveyor 1 by the intake action by the operation of the blower 4. Since the web a is sucked, and thus the web a is attracted and conveyed to the surface of the conveyor a in a tensionless state, the liberation of the web a is restrained, and therefore, no harm is caused together with the conveyor 1 without causing slippage. Instead, they are transported while undergoing predetermined processing.

[0006]

【Example】

 An embodiment of the web conveying device according to the present invention will be described below with reference to FIGS.

In the figure, a is a long strip-shaped web such as a woven fabric, a knitted fabric, a non-woven fabric, etc., which is placed on a strip-shaped conveyor 1 made of a breathable net-like material on the front and back without tension. For example, after being introduced into the illustrated drying processing chamber 2 and subjected to a drying treatment, it is carried out from the inside of the processing chamber 2.

In the conveying path of the conveyor 1 on which the web a is placed, one or more or a suitable number (three in the illustrated example) of suction nozzles 3 are provided so as to face the lower surface of the conveyor surface on which the web a is placed. The suction nozzle 3 is connected to the suction side of the blower 4, and the suction force of the suction nozzle 3 is adjusted by adjusting the rotation speed of the blower 4. The suction nozzle 3 may be a large number of holes as shown in FIG. 2 or may be slit-shaped openings.

Further, in the illustrated example, in order to reduce the heat loss in the processing chamber 2 due to the suction action, the exhaust side of the blower 4 is communicated with the processing chamber 2 to recover heat.

The belt-shaped breathable conveyor 1 is suspended by two rotating drums 5 and 5 and endlessly rotated by a known means (not shown), and is supported on the lower surface of the conveyor 1 on which the web a is run. Rolls 6 are provided, and guide rolls 7 and 8 are provided in front of and behind the conveyor 1, respectively. In the figure, 9 is a hot air blowout casing provided in the processing chamber 2, 10 is an air supply fan, and 11 is a heat exchanger.

In the apparatus of the above-described embodiment, the web a placed on the conveyor 1 in a tension-free state is constrained by the suction action of the three suction nozzles 3 in a state of being attracted to the surface of the conveyor 1 and thus the conveyor a. After being subjected to a drying process while being conveyed integrally with the conveyor 1 without being idled on the sheet 1, it is carried out of the processing chamber 2. The device of the present invention is not limited to the above-mentioned drying device, but can be used as a conveying device for various web processing.

[0012]

[Effect of the device]

 According to the present invention, when the processed web is placed on the conveyor in a tensionless state and is conveyed, the conveyor has a net shape with air permeability on the front and back sides, and a suction nozzle is opened on the lower surface of the conveyor section of the web by the conveyor. Then, by sucking the web through the net-like conveyor, the web is attracted to the conveyor surface and constrained so that the web is transferred integrally with the conveyor, so that the looseness of the web on the conveyor can be surely prevented, and thus, the movement on the conveyor can be surely prevented. This has the effect of eliminating slippage and other adverse effects due to free movement, and enabling the prescribed processing to be performed without any problems.
