Abstract

The invention relates to equipment for shoe manufacturing and advantageously provides for improving the quality of glue applied to parts of shoes attached to a shoe. The device has a container with glue, inside which a drive glue-supplying shaft is fixed. Above the driven glue shaft there is a glue-applying shaft with an elastic surface, fixed to the rod of the power cylinder by means of a fork with an axis. At one end of the axle, the overrunning clutch is reinforced. The glue shaft with a power cylinder moves to the area of the pad with fixed parts and applies glue to the bottom of the shoe. During the return stroke, the glueing shaft is braked by the overrunning clutch and the applied glue is rubbed onto the surface of the shoe part. 3 il.

Description

The invention relates to equipment for shoe manufacturing and advantageously provides for the application of glue to parts of the bottom of a shoe, mounted on a shoe.

The purpose of the invention is to improve the quality of glueing the details of the bottom of the shoe, attached to the shoe.

FIG. 1 shows the proposed device, side view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 1.

The proposed device is intended to work as part of the KPC automatic line, directly for assembling glued rubber shoes, mounted on the shoe, mounted on the KPC frame at the appropriate position,

The device for applying glue to the details of the bottom of the shoe consists of a container 1 with glues, inside of which is glued

a shaft 2 with a grooved surface having a pneumatic drive of rotation 3 and a device 4 for adjusting the thickness of the adhesive layer. The adhesive shaft 2 comes into contact with the adhesive shaft 5 mounted on the axis b, placed in the fork 7 mounted on the rod of the pneumatic cylinder 8 pivotally mounted on the frame. There is an overrunning clutch 9 at one end of the axis 6.

The applicator shaft 5 is kinematically connected through a KPC air distributor shaft with a pad 10 sensor. A device 4 for adjusting the thickness of the adhesive layer includes a spring-loaded strip 11 and an adjusting screw 12 cooperating with it. The spring-loaded strip 11 for adjusting the thickness of the adhesive layer is connected to the bottom of the container 1 with the adhesive by means of an axis parallel to the axis of the adhesive-glue shaft 2, can be rotated around this axis

The level of glue in the tank is maintained automatically.

A ratchet mechanism 14, a gear 15, a gear rail 16 mounted on the rod of the pneumatic cylinder 3 is mounted on the shaft 13 of the glue-clamping shaft 2. To hold and center the pad in a vertical position, it has a centering-holding mechanism 17, Controls the operation of pneumatic cylinders 3, 8 and 18 from the air distributors and cams mounted on the KPC camshaft (shown in the picture).

 The device works as follows.

In accordance with the conveyor stroke, the cam camshaft rotates with the air distributors controlling the operation of the pneumatic cylinders. When the pneumatic cylinder 18 is activated, the divorced tongs of the centering-holding mechanism 17 converge, cover the shoe with shoes and thereby hold it during the glueing operation.

Further, according to the sensor 10 signal of the presence of the pads, the pneumocil ndr 8 is activated, on the stem of which the adhesive shaft 5 is mounted. The adhesive spindle 5 with glue, moving forward, comes to the position of glue pads with shoes.

The glue shaft 5, moving progressively, moves to the position of the pad with the shoes by the rod of the pneumatic cylinder 8, rolls over the block, evenly glueing the details of the bottom of the shoe. Then, in the opposite direction, the rotation of the adhesive shaft 5 is wedged by the rollers of the overrunning clutch 9 — the adhesive applied by the already retarded shaft 5 is rubbed in. The hinged installation of the pneumatic cylinder 8 allows the adhesive shaft 5 to completely cover the curvature of the bottom surface of the shoe. Then, the Glueing Shaft 5 returns to the position of receiving glue from the glue-feeding shaft 2, after which the tongs of the centering-holding mechanism 17 are retracted by the pneumatic cylinder 18 from the pad.

Since the operation of the pneumatic cylinders 3 and 18 occurs simultaneously, while

At the same time, the rod of the pneumatic cylinder 3 moves the toothed rack 16, transmitting the rotation to the gear 15, which is engaged with it. Further rotation of the ratchet

The mechanism 14 is transmitted through the ratchet wheel to the shaft 13 of the glueing shaft 2, which supplies the glue to the surface of the glue applicator shaft 5, which is in direct contact with it.

When simultaneously actuated by the pneumatic cylinder 18, the working stroke is made, and by the pneumatic cylinder 3 - idling. Because of this, the rack 16 is notched, moving to its original position, due to the slipping of the ratchet paws.

The mechanism 14 does not allow the gear 15 to rotate, nor does the glue shaft 2 connected by the gear 15 to the shaft 13.

The cycle of operation of the device is repeated in accordance with the conveyor cycle.

The proposed device allows to improve the quality of lubrication due to the reciprocating movement of the applicator shaft and due to the overrunning clutch, which provides braking of the shaft during the movement, the productivity of the conveyor is achieved by installing the device on the conveyor, which eliminates the operation of transporting the parts and releasing the worker.
