Description

[Detailed description of the invention]

The present invention relates to a method for treating products, such as parts of shoes, having a coating of a moisture-curable composition, and more particularly to an apparatus for treating such products, comprising a support member for the untreated product, and a support member containing the support member. The present invention relates to a processing apparatus comprising a rounding chamber and ninth product processing means for supplying heat and moisture to the chamber to process a product supported within the chamber. Devices for processing products other than shoe parts, such as printed matter, are known. Such processing equipment typically has a tunnel-shaped chamber into which heat and moisture are supplied, during which time a product supported by a support member moves through the chamber. Such devices are usually coupled to a printing press via a feeding device that continuously supplies printed products to the chamber. The product is processed through the chamber at a relatively slow speed. Both ends of the tunnel are always open since the products are fed automatically and continuously, so the product processing means are located in the center of the tunnel. Apparatus of the above type for treating shoe parts (with or without coatings of moisture-curable compositions) are also known. This device is called a thermosetting device, and when it is placed over the foot mold and passes through a tunnel, it is heated and heated, which allows the shape of the foot mold to be shaped inside the ship. It maintains its shape in the finished product. In this case as well, the 5N4 speed of the product through the tunnel is relatively slow. □ When subjected to chain elongation treatment (hardening treatment), it becomes sticky due to heat, and as a liquid composition that converts into 1-9 urethane, which can instantly establish a strong adhesive bond with the facing adhesive surface, that is, the resin surface. Selected urethane polymers of

ζq) It is desirable that the curing action of the first adhesive be carried out relatively quickly. It turns out that speeding up the hardening action is less than q) magically beneficial. That is, if the adhesive action of the shoe q) parts is carried out slowly, it must pass 1.
The relatively large space of the equipment and the slow curing process and the large number of parts placed on the curing line at any given time result in e.g. This is because as the process nears the end of the process, there are inconveniences in terms of personnel, and problems arise when holding adhesive parts between lines. Therefore, the above-mentioned known type of device 1 cannot be conveniently used! ! do not have. Furthermore, in the known device C1, above, when a particular process is carried out in the device, other actions are not carried out together with it. Therefore, in the case of printing technology, if you think about it, after processing and drying, there are nine Fi optical products. Then, in Plm, different shoe manufacturing depends on the degree of heat set C] that occurs, in the case of heat set 2/false: about 1 m, thus, depending on the operating conditions of such equipment, its 'M purpose In rounding to achieve this, there is no need for such effective control, apart from control for achieving operational economy such as space saving, energy saving, and improving the flow of workpieces. However, in the case of adhesives of the above type 1 soft, one independent and interrelated process is used for the rounding to achieve sufficient adhesion, namely the curing action and the active activation action, and therefore especially the first part of the transformation action. During the 7th stage, i.e. the curing action, I
& I understand that close control is a must. The above known equipment
TSM is not suitable for strict control. SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for use in processing products having a moisture curable composition of 111. According to the working principle of this device, "Karl!!! Agricultural hardening"

[
It can be carried out under strictly controlled conditions and at relatively high speeds that match the velocity of the flow of the processing fins, but does not require a large amount of space or the processing of the workpiece. I don't know if it's a question of how it turned out. With the above objects in mind, the present invention provides, as one of its aspects, a product, for example a silver halide device for 4k parts, carrying a film of a moisture curable composition comprising the following means: Namely, there are three stages, a supporting member for unprocessed crystal production, a chamber for accommodating the supporting member, and a rounding part for supplying heat and moisture to the nayanper to process the product supported in the chamber. It is a product processing means.This place 11 & place has the following characteristics.That is, its characteristics and Fi,
During processing of the product, a support member is enclosed in the chamber FP3. and a means for supplying steam into the chamber by irradiating the product with infrared radiation from the product processing means, 1.

1) The intensity of infrared irradiation, the time period during which the 111111 product is exposed to infrared rays, and 4v) the period during which the air is supplied is provided with control means. As understood herein, in order to use the scissor crease according to the present invention, firstly, the untreated #product is controlled, sealed in a 9-filling chamber, and encapsulated during the death period. receive. In this way, it is possible to control the temperature at which the composition hardens during such processing, and also to control the timing of the saponification process and the flow of processed products into and out of the equipment, allowing for efficient use of manpower and at the same time reducing the A strong hardening action is maintained. In the device according to the invention, it is preferred that the support member is movable between an loading position and an operating position, in which the support member is accommodated in the chamber. Furthermore, in order to provide a sealed environment, the support member preferably carries a screen, which closes the chamber when the support side is placed in its operating position. Furthermore, it is advantageous if one more support element supports the screen. That is, when the support member is folded into its loading/unloading position, the chamber is again closed by the screen. This first protects the operator from flying infrared radiation while the support member is in its rIM#I4/removal position.
Furthermore, the silk NuClean allows the steam to be expelled from the chamber. That is, at the end of the operating cycle, the air is ``swept'' (e) from Nuclean to the atmosphere. 〃・As a result, there is no shrinkage in the chamber, and at least it is pumped lightly to the extent that it is not disadvantageous. It is understood that if parts of the equipment were to fall into contact with fog or forge, they would stain the inside of the ship. Preferably, the product processing means includes a grate heater housed within the chamber. That is, the heater grate exposes the product supported within the chamber to infrared radiation. In order to achieve high efficiency by using a high-performance heater,
In addition, the product processing means can also blow frost over the plate heater to generate steam in the chamber.
It is desirable to include JS means. Thus, it has the function of irradiating the heater wire product with infrared a, and the function of generating steam within the Nayanvar. Preferably, the 11% means includes 97 or more nozzles directed at the impingement surface of the plate heater. When the water collides with the collision surface, the hammer turns into steam,
There is such steam in the chamber! <This is to fill the body. In this way, the chamber has a uniform VC m
An atmosphere with ft- is formed. In another aspect of the invention, the invention also provides a product, such as a sheath part IfI, having a layer of a moisture curable composition having the following characteristics: The present invention provides a method for processing I using the above-mentioned apparatus 11. That is, the characteristic is that the product is supported in a sealed chamber for 5 to 25 seconds, and during this period the product has a temperature range of q2θ to 250°C.
Infrared tS is emitted from a radiation source having IiiffigrE, and during this period, steam is supplied to the chamber in such an amount that the humidity of the atmosphere in the chamber is maintained between Sθ and 1.0”C. This will be explained in more detail.According to the dice according to the present invention,

The heater 44Fi irradiates infrared rays to the sea bream products supported on top.The heater 44Fi has the shape of an aluminum grate with a heating element embedded therein. Furthermore, the irradiation surface of the heater 44LD is heated to increase its emissivity. The product processing means of the illustrated apparatus further includes a steam generator stage capable of supplying steam into the chamber 80. This steam generating means includes a pair of mist nozzles 46'gr mounted on the body surface of the Agile No. 8 and making use of the size of this body surface. A nozzle 46, which communicates with a water supply by a pipe 48, is directed toward an upward projection 50 of triangular cross section mounted on the grate heater 44, and more particularly on the top surface of the grate heater. The protrusion 6G acts as a colliding surface for agricultural water, which quickly converts it into steam. The steam generated during + and ζ acts to be uniformly distributed throughout the chamber 80. It is hereby understood that nozzles of any size,
By controlling the pressure at which water is supplied to this nozzle, the amount of water supplied at any given time, and thus the amount of steam generated as described above, can be adjusted with precision. Rounding off the above objectives lr, the illustrated device also includes control means, including a timer 601, for determining the period of time during which water is supplied to the nozzle 46 as described above. Furthermore, the control means includes another timer 621 for controlling the actuation of the piston cylinder a 128 such that after nine controlled periods the support member 16 is withdrawn from the chamber. Furthermore, the control means includes a mixer moderator 64 for controlling the infrared radiation intensity by detecting the humidity of the radiation surface of the heater 44.

When using and carrying out this method, the atmosphere in the chamber 80 in which the bathtub S is enclosed is
Air humidity is maintained at a temperature of SQ to 60°C. At this time, care must be taken to avoid the possibility that by the end of the operating cycle, a large amount of steam has accumulated in the chamber, causing the steam to condense when the chamber is opened to the atmosphere. The goal is to control the amount of steam so that there is no To achieve this objective, a timer should be applied so that steam is supplied for a period such that the desired humidity is sufficiently maintained throughout the operating cycle. What we know so far is that if the dimensions of the nozzle 46 and the water supply pressure are sufficient to achieve a pointless ejS degree of b o 'ca, then the steam supply time can be , the humidity is maintained at a dew point of SQ to 60° C. for the remainder of the cycle, assuming chamber 80 is sealed. It has been found that maintaining a humidity tm point near 60 DEG C. creates an optimum atmosphere for dampening the shoe without running the risk of staining the shoe with condensed water. Moisture in the atmosphere or hardening of the composition is essential, whereas
Application of heat serves to increase the rate at which curing occurs. Since the material of the soft carapace is usually leather or polymer material, it is known that the optimum surface temperature of the heater is on the order of 3gθ°C, if only one point is given to the curing speed. However, at 310℃! ! When using a heater food with iItimlii, J! +Activation't- has been found to form a skin on the coating that makes it difficult to activate. On the other hand, if using ll111IK- and applying a directly molded sole unit to 1 shoe, the temperature at which the material of such a sole unit is molded, which is considerably higher than 90°C, will regenerate the saponified solution. sufficient to activate and achieve sufficient adhesion. Thus, if the shoe is a directly molded unit tP1, 3jO in the main assembly.

If P is set lower than this, the period up to 25 seconds can be tolerated.On the other hand, if the temperature is higher than the above bond, it is understood that even a small period of Fi5 seconds is acceptable. There is. The dimensions of the heater 44 in the front-rear direction and the width direction are also larger than the soles of the shoes S that have been stuffed. This ensures that the amount of infrared radiation applied to the shoe is distributed substantially evenly over the surface of the shoe sole, regardless of variations in height from the sole contour and distance from the heater. This is for the purpose of Furthermore, as mentioned above, if the wavelength band irradiated by the heater 44 is appropriately selected, the energy will be strong regardless of the material or color of the soft carapace, and even if it does not partially affect the output of the heater 44. You can catch catfish. 8. If the steam is distributed all over the pump, I! The rIs achieve substantially uniform moisture absorption. Furthermore, problems caused by rounding corrosion and hard water when only tap water is supplied to the nozzle can be avoided. Furthermore, since the entire inner surface of the chamber 80 and the screens 52 and 54 have a good reflectance of infrared light,
