Description

A semi-automatic machine is known for molding footwear from the inside, made in the form of rotating in a vertical flat plane, such as carousels, press points, and metal sliding pads. The construction of the pads does not provide the necessary fit for the workpiece of the pad, due to the presence of a free P1just; 1n tva between its parts when the pad is open.

In the described semiautomatic device, this disadvantage is eliminated by the fact that the individual parts of the pads are made telescopically interconnected, which improves the quality of forming the blanks.

FIG. I shows a semi-automatic shoe molding machine; in fig. 2 - its drive; in fig. 3 press points. view from above; in fig. 4 is a diagram of a pad in a closed state (State; in Fig. 5 --- the mechanism of shifting the shoes of the pad.

The semiautomatic device is made in the form of a carousel / rotating in a vertical plane on the main shaft 2 and carrying discs 3 for fastening press points 4 and the Maltese cross 5 to rotate the carousel, which is driven by the motor 6. The electric motor 6 is mounted on the shaft 7, which causes the helical gear 8 to rotate, which is free to sit on the shaft 9 of the screw 10. The socket 8 is equipped with an electromagnetic clutch 11, the current to which is supplied through brass rings 12 and graphite brushes 13. Electromagnetic clutch II attracts a bark M, 0 | sajenes .9 on the shaft of the screw 10 on the diametrically opposite dvzh keyed in and peremeschayuschi11s osevo.m naprav.yunii. The spring 14 is retracted to its original position 15. The worm to 10 is engaged with a worm gear J6 fixed to the shaft key 17. At the end of the shaft 17 there is a carrier / 6 equipped with a finger 19 with a free-sided bird it roller 20. koto .NO 127921

During rotation, the carrier 18 enters the cutout of the Maltese cross 5 of the carousel / and periodically rotates it, as a result of which the Maltese cross 5 turns the carousel / onto the part of the circle corresponding to the number of press points 4 fixed on the carousel 1.

The pressure points 4 are intended for lining, centering and securing the sole to the shoe. Each press-hole 4 has a housing 21, covers brackets 22 with a spatial track footprint 23 installed on folding housings 24, a lid 25 g with a rubber Pneumatic cover 26 and a lid closing and opening mechanism 25. A latch 27 is attached at the front of the key 25, the retaining clip 25, which is connected to a freely turning roller 28 with the brush-shaped 29 fixed at its ends, the latter are engaged with the rails 30, connecting the crossbar 31 between them. In the middle of the crossbar 31, the hook 32 is fixed, in which The OiCTanoBe of the carousel 1 enters the end of the cylinder rod 55, which serves to close and open the lid 25. When lifted, the lid 25 rotates 90. In the closed state, the lid 25 is fixed by a hook 34, which grips its latch 27. Air is fed to the pneumatic chamber 25 through a rubber strap. through the roller 28 and shtutuser 55. On the pneumatic chamber 26 is fixed rubber pad 55, the contour of which corresponds to the contour of the base.

The metal sliding block is made of separate parts telescopically connected between them. It consists of the front part 57, including its toe part to the UE section, the right part 5 from section VII to the end of the block and the ridge 39. When the length of the block is shortened (the shortened length of the block in Fig. 4 is shown below: and the block in the normal position - the dotted line), the exact part 38 is pushed by its part VII-VIII into the slot of the front part 57, cut inside it between the cross sections VI m VII, and the reduction is the transverse dimensions of the block | 40 placed between sections / and / / pads.

For moving the exact part 38 of the pad, and also for raising and lowering the crest 39 on the lower side of the ash part, petika 41 is fixed, and on the crest 5.9 there is a hole for the finger 42. On the mechanism for moving apart the parts of the shoes between his cheeks 43 there is a sector 44 that can rotate around axis 45.

One end of the sector 44 interacts with a fixedly mounted on the carousel 1 sector 46, and the other with Reyk-41 41-exact part 38 pads. When the cheeks 43 are rotated near the axis 47, sector 44, rolling around the sector 46, with its other end, locks the rail 41 with the exact part 38, and the pad is reduced in the longitudinal direction. When installing H1, ek 43 in a vertical position, the pad sits on a normal length, at which the nose part 57 and the exact part; -, 5.5 are butt-joined in section VII. Lowering and raising the ridge 39 of the pad is performed by the helper 48, the upper end of which is connected to the ridge 39 of the pad through palpe, 42, and the lower end is equipped with a roller 49, interacting with an eccentric 50. fixed on a semi-automatic machine.

The work of the machine is as follows.

In the outgoing position, the sliding block, shortened in volume as indicated above, extends forward. A stocking is manually put on it and air is fed into the cavity of cylinder 51, the rod, which is in engagement with the sliding block assembly, moves the latter into the vertical position. During this movement, the pad extends and longitudinally adjusts its normal length.

Thus, preforming of the inside of the right and toe parts of the shoe and exact alignment of the pad trace with the “stocking” trace takes place.

After the pad is installed in working position, air is supplied to the bottom of the cylinder 52, the rod of which is engaged with the mechanism driving the LD, EKI 43 press points 4. At this, the brackets 22 are closed and compress the "stocking along the edge of the pad trace all over the meter. After that Manually impose a sole, the centering device for which the vertical planes of the brackets 2-2 serve. Then, the lid 25 is manually closed. As soon as it is rotated at an angle of about 60, air is fed into the cavity of the cylinder 33, the stem of which produces the final closure of the lid 25. After that, the electromagnetic clutch // actuator is turned on, which with the aid of a box M, a worm gear pair 10- 16 and drove 18; informs movement of the Maltese cross 5, turning the carousel /. During the rotation of the carousel, air is supplied to the pneumatic chamber 26 to fasten the sole, and the eccentric 50 lifts the crest 39 of the shoe, as a result of which the upper of the shoe is stretched in the transverse joint.

This is where the process of molding the shoe from the inside ends. The shoes are kept in this condition and removed from the semiautomatic device after turning the carousel 1 to 360. After the car turns around, the carousel / air flows into the cavity of the cylinder 33 from the back side, resulting in the opening of the cover 25 with a pneumatic chamber 26. As soon as the lid of the pronepimets is at an angle of 45 air is fed into the cavity of the cylinder 52, as a result of which the clips 22 of the pressure point 4 open in parallel with the opening of the clamp 25, then the air is fed into the cavity of the cylinder 51, and the sliding block moves forward, shortening in length. The molded semi-pair of shoes is removed from the pad, a new "stocking" is put on the pad - and the cycle of operation of the semi-automatic machine is repeated.

Subject invention

A semi-automatic machine for molding footwear from the inside, made in a vertical rotating carousel, carrying press points and metal sliding pads, characterized in that. In order to improve the quality of the molding of the blanks, the individual parts of the pads are made telescopically connected with each other.
