Description

The invention relates to the leather haberdashery industry, to equipment for fastening buttons on leather haberdashery products: gloves, bags and others. e each bunker, a guide channel consisting of two parts, and a spring-loaded cutter located between the channel parts, installed with the possibility of reciprocating movement from the drive, a matrix, a mechanism for transporting the button part to the matrix, and a percussion mechanism l. However, this device is not sufficiently reliable in operation, since the details of the buttons often get stuck in the shut-off device. The purpose of the invention is to increase reliability. This goal is achieved by the fact that the cutter is made in the form of a plate located in a plane, perpendicular to the guide channel, and having a slot with a configuration corresponding to the shape of the part of the button. FIG. 1 shows the device, a general view; in fig. 2 is a kinematic diagram} in FIG. 3 - button feed mechanism; in fig. 4 - cutter; in fig. 5 shows section A-A in FIG. 4. The device contains the mechanisms for feeding the details of the buttons, the drive, the percussion mechanism and the mechanism for transporting the part of the button to the matrix. The mechanisms for feeding parts of buttons are similar in design and include each bunker 1 with grooves 2 along the profile of the corresponding part of the button, an electric motor 3 for transmitting rotation of the bunker 1, a guide channel 4 formed by a plate 5 and stickers B, 7 and 8, and a cutter dividing channel 4 into two parts. The cutter is made in the form of a plate 9 located in a plane, perpendicular to the channel 4, and having a slot 10 with a configuration corresponding to the shape of the part of the button. Plate 9 is fixed in brackets 11 and 12 with screws 13. Brackets 11 and 12 are interconnected by sleeve 14,

. placed in the housing 15 and having a pin 16 with a spring 17 and an adjusting screw 18. The bracket 12 is spring-loaded with respect to the housing 15 by a spring 19. The portions of the channel 4 above and below the shut-off device are offset relative to each other by the stroke of the shut-off device.

The drive contains the main shaft 20, on which the cam 21 of the transport mechanism for the part of the button to the die 22 and the cam 23 of the impact mechanism are fixed. A brake disc 24 is mounted on the left end of the shaft. 20, a flywheel pulley 25 and an electromagnetic clutch 26 for single-impact operation of the device are mounted on the right. A motor 27 serves to communicate the rotation of the shaft 20.

The percussion mechanism serves to rivet the two parts of the button and hold a spring-loaded double-arm lever 28 on the axis 29, pivotally connected to the rod 30. To the rod 30, the drummer 31 is attached. 34 The levers 35 and 36 serve to engage the pins 16 of the respective cut-offs.

The transport mechanism serves to receive the button parts from the guide channel of the respective feed mechanism and advance them to the Matrix 22. The mechanism includes a lever 37 on the axis 38, connected to a slider 39, to which the spring steel strip 40 is attached. Above the bar 40. the receiver 41 is mounted. A spring-loaded table (not shown) is installed in the matrix zone.

The device has an optical projector (not shown) for orienting the product relative to the working tool. To control the device serves as a remote control 42 and the pedal 43.

The device works as follows.

Having filled up the bunkers 1 with parts of the electric motor 3, through the slots 2, the details of the buttons fall into the channel 4 above the plate 9 of the shutoff device. Then, the motor 27 is turned on and the pulley-flywheel 25 turns. there is a pulley with a shaft.

When the shaft 20 rotates, the cam 23 will lower the barbell 30 s through the jib 28

drummer 31, the projections that fall into the hollows of the jaws 33. The jaws 33 clamp the part of the button located in them. Further lowering of the drummer 31 occurs together with the tongs to the stop. This moment corresponds to the contact of the ticks with the product lying on the table. Continuing to descend, the impactor 31 emerges from the hollows of the jaws jaws 33 and moves them apart. The part of the button under the action of the punch pierces the product and enters the part of the button located on the matrix 22. At the moment of combining the parts of the button, the strap 40, which previously held the part of the button on the matrix 22, returns to its original position.

At the same time, the roller 32 deflects the lever 35, which has a knuckle on the pin 16 of the cutter of the left-side button feeder, and the part falls into the receiver 41. At this point, the riveting of the button parts is completed. The pliers rise up. The roller 32 acts on the lever 36, which presses the pin 16. the shut-off valve of the right-hand feeder, and the plate 9 transfers the part of the button to the part of the guide channel 4 under the shut-off device. The part falls into the channel and falls into the tongs. In this approach, the strap 40, capturing the button part from the receiver 41, transports it to the matrix 22. In this position, the shaft 20 completes one turn and the device is ready for the next cycle.
