The present invention relates to a humidifier of the shoe upper. In particular, the present invention relates to a humidification apparatus for a shoe upper, which is assembled along a conveyor valve between two adjacent working ends in a shoe manufacturing apparatus. It is known that the shoe upper should be humidified before any particular assembly process. In a conventional assembly line of any type, the humidification process is performed by separating all uppers from the shoe bones and placing them between two supports passing through the steam release end. Each upper is then covered in the shoe goal and sent to another successive assembly step.

As another conventional humidification method, a separate humidifying device separated from an assembly line may be used. The transferred upper is taken out of the transport pushpin and inserted into the supporting object of a separate humidifier. At the end of the humidification process, the upper is placed on the front wheel of the assembly line, which, together with the upper, is removed from the above-mentioned humidification device. And sent to the next continuous work stage. In each case, there are some practical shortcomings in the upper humidifier, although temptingly humidified. In fact, they need a stop time to put the upper on the shoe bone, and a lot of time is required to put the shoe bone on and off the assembly valve and the humidifier.

Another drawback is that the forward movement of the assembling valve and the forward movement of the humidifier are completely synchronized and balanced to avoid unnecessarily equilibrium or to stop the assembly line periodically to achieve this equilibrium.

Another drawback is that the operator has to wait for all humidification processes.

The purpose of the present invention is to provide a humidification device of the shoe upper without the above-mentioned crystal. In particular, it is an object of the present invention to provide part of an assembly line and to provide an automatic humidification apparatus as a whole.

Another object of the present invention does not need another manual operation for selecting the intermediate position of the shoe upper in the working process, and can be a regular and continuous movement of the assembly belt to reduce the cost of manual operation and automatic humidification to increase productivity To provide an apparatus.

According to the invention, the above and other objects are achieved by a humidifying apparatus for a shoe assembly line consisting of a plurality of suction devices, each connected to a steam supply and recovery conduit connected to a steam generator and a working stage of at least one whole apparatus. The work stage is aligned with the transport pushpin of the shoe upper overlaid onto the shoe bone. Each work end is divided into hollow fan-shaped up and down extending horizontally away from the support structure to form a movable support for the upper aligned on the support of the transfer wheel. The above-mentioned hollow fan-shaped upper and lower sides are formed with a plurality of through-holes directed toward the moving support side and directly connected to the steam supply and the suction conduit.

Referring to the present invention in more detail based on the accompanying drawings as follows.

The humidifier of the present invention comprises a loading structure (1), on which a steam generator (2) and a suction device (3) are mounted. The steam generator 2 is connected to the lower hollow fan 5 of the humidifying stage 6 via a conduit 4. The suction device 3 is connected to the upper hollow fan 8 of the same humidifying stage 6 via a conduit 7.

In the illustrated embodiment, the upper 9 is mounted on a known push wheel shelf 10. The upper 9 located on the upper and lower sides is placed on the support 12 which is integrally formed on the pusher lathe 10 together with the shoe bone 11. When the upper portion 9 is humidified at the tip portion thereof, the tip portion is separated from the tip portion of the shoe bone 11 and inserted.

This positioning of the upper 9 can be done manually during the transfer of the upper to the thrust ring or the tip can be separated and inserted by means of a longitudinal rod 20 arranged so that the upper is in line with the leading end 13 of the upper limb 8. Can be. The tip end of the foot bone 11 is the tip end of the upper leg 8 when the contact ring 10 is moved at right angles in FIGS. 1, 2 and 3, that is, in the direction of the arrow 21 in FIG. 4. The tip of the upper 9 passes through the space between the upper and lower sectors 8, while passing through the upper part of.

During this passage, the tip of the upper 9 is covered and humidified with steam from a plurality of through holes 14 formed in the upper portion of the fan 5. The remaining steam is sucked through the through hole 15 formed in the inner side of the fan 8.

The suction of the remaining steam is necessary to avoid the expansion of the adjacent area of the shoe assembly line with moisture and at the same time to avoid the wetness of the shoe bone 11. As already mentioned, the leading end of the shoe 11 is shielded by the leading end 13 of the upper rim 8 for more effective processing.

The tip 13 is preferably covered with a soft layer 16 such as, for example, Teflon or plastic, in order to avoid being scratched by the tip 13 of the shoe bone 11 during the advance of the contact ring 10. In the process of sucking steam, electrical resistors 17 are disposed inside all of the fan shapes in order to prevent steam from condensing on the shoe bone 11 which is colder than other parts.

The resistor 17 has a dual purpose of heating the upper side of the fan 8 and reviving the tip of the upper before assembly. Heating of the upper side of the fan 8 can alternatively avoid condensation of vapor in the shoe bone 11.

Although the tip and the bottom of the shoe are moved in a state where the front end and the bottom of the shoe are sufficiently protruded along the guide path formed by the upper and lower fan shapes 8 and 5 in the shelf type wheel ring 10. The thrust rings can be used. In each case, the thrust rings mentioned above should be configured so that the upper to be humidified can protrude sufficiently.

2 shows that the rear axle of the shoe is placed in a humidification position to humidify the recess of the shoe. The humidifying stage is not limited in this second type of treatment. It is preferable to operate in the reverse direction. Therefore, steam circulates from the upper side fan 8 'to the lower side fan 5'.

In order to achieve this circulation, in the humidifying stage 6 conduits 7 ′ and 4 ′ are connected to the steam generator 2 and the suction device 3, respectively. This steam circulation direction is preferably supplied so that steam is directed toward the side of the upper leg (18) of the upper (9) so that the steam can be directed to the sole (19) side of the shoe after direct humidification. At this time, the shoe bone 11 is sufficiently protected by the upper (9) and the sole (19) does not require special protection otherwise. The lower guide 5 'is formed with an upper guide part 22, and the shoe bone 11 is moved upside down while the shoe bone 11 is inverted. The guide portion 22 is preferably provided with a through-hole in order to prevent the condensation of steam therein.

Humidification device of the present invention may comprise one or more humidifying stage (6) consisting of a lower side portion (5) and the upper side portion (8), respectively. The humidifying device. May be disposed on the inside and outside of the assembly belt. 23 according to its shape and the arrangement space for the installation of the assembly belt 23. Alternatively, the humidifying device is movable and detachable from the outside. It may be installed. In each case the work is fully automatic and does not require operator intervention and is inserted on the assembly belt 23 prior to each assembly process of the upper, such as before assembly of the tip and sole of the shoe, which is carried out in succession to other processes.

Each humidifier comprising a humidifying stage 6 is automatically operated independently of the other continuous process stages required for shoe manufacturing. This function of the humidifying stage 6 can match the humidification treatment time for the shoe to the average speed of the assembly belt 23.

For this reason, the humidifying stage 6 can reduce working time and increase productivity. In addition, the humidifying stage 6 can be installed on any type of assembly belt 23 having a continuous or controlled speed for shoe assembly.

Although the present invention has been described in the illustrated embodiments, modifications or variations are possible without departing from the spirit and scope of the invention.
