Description

Bottom section near infrared conveyor

The present invention relates to a shoe making machine, and more particularly to a bottom-end near-infrared conveyor.

A conveyor generally used for the lamination process of a shoe upper and a sole for conveying the upper and the sole for the operator to clean, dry, glue, dry, and finally fit the upper and the sole respectively. The bottoming process at the bottom of the uppers. The conveyor substantially comprises a machine table, a conveying unit disposed on the machine table for carrying the sole and clamping the upper, and a plurality of intervals are mounted on the machine and can be respectively carried and clamped to the conveying The sole and the upper of the unit are dried in an oven.

Referring to Fig. 1, the gripping opening 100 of the conveying body for gripping the upper surface of the upper conveying member 10 for the upper 9 is fixed and cannot be adjusted (see Fig. 1). Therefore, when the above-described bottoming process is performed for the uppers 9 of different sizes, it is necessary to replace the gripping conveyance member 10 having the size of the appropriate gripping opening 100 in order to apply the gripping upper 9.

In addition, since the sizing of the upper and the sole is applied by hand, the thickness of each layer formed on the sole and the upper is uneven, and each glue layer is dried by a general oven. The inside gradually takes away the moisture, so that the glue layers are fixed at a drying time, and each glue The thickness of each layer varies from thickness to thickness, resulting in poor overall adhesion when the last upper is attached to the sole.

Accordingly, it is an object of the present invention to provide a bottom-end near-infrared conveyor that can be adapted to hold different sizes of uppers and to solve the problem of uneven thickness of the glue layer.

Therefore, the novel bottom-end near-infrared conveyor is used for conveying a plurality of soles and a plurality of uppers for the operator to clean, dry, glue, dry, etc. the soles and the uppers, and finally the soles The bottoming process is applied to the bottoms of the uppers respectively. The bottom-end near-infrared conveyor comprises a machine table, a conveying unit, and a plurality of near-infrared ovens.

The machine includes a first end and a second end disposed oppositely, and two working areas on opposite sides.

The transport unit is disposed at the top of the machine and is located in the working sections and extends along a first direction from the first end toward the second end. The conveying unit comprises a conveyor belt that is circulated around the first direction, and a plurality of carrying devices arranged in the conveyor belt. The carrying device has a support member protruding perpendicularly from the conveyor belt, two trays corresponding to the heights, and extending from the top end portion of the support member toward the working areas, respectively, for receiving the uppers, and corresponding heights and An upper gripping group extending from the middle portion of the support member toward the workpiece regions and for holding the uppers. Each upper grip set can be adjusted to accommodate different sized uppers.

The near-infrared ovens are spaced between the first end and the second end of the machine slot along the first direction, and respectively for the transport order The element is subjected to near infrared ray irradiation.

The effect of the present invention is that each upper grip group can be adjusted to accommodate different sizes of uppers. In addition, the present invention is dried by the near-infrared oven by the near-infrared ray irradiation through the glue layer formed on each shoe upper and each sole, so that the uneven thickness of the rubber layer can be made under a fixed drying time. The uniform drying degree can be uniformly achieved everywhere, and the adhesion between the rubber layers is better when the uppers and the soles are attached.
