(54) DEVICE FOR FEEDING LONG-DIMENSIONAL

PRODUCTS

I

This invention relates to mechanical assembly production, in particular, to devices for assembling heat exchangers.

A device for feeding long products when assembling heat exchangers is known, which comprises a feeding mechanism mounted on a frame and a driving carriage placed on the guides 1.

However, this device is complicated in design and does not provide cyclical supply of long products to machine tools with a cyclic mode of operation.

The purpose of the invention is to ensure the cyclical flow of the product.

The goal is achieved by the fact that the device for supplying lengthy products when assembling heat exchangers, comprising a feeding mechanism mounted on the frame and a driving carriage placed on the guides, is provided with opposed springs on the carriage in opposite directions with rollers on the other and also bilateral additional guides, located parallel to the main guide, and the folding spring-loaded ends.

pivotally fixed on bilateral additional guides and alternately interacting with the rollers shtang, in contact respectively with bilateral additional guides, with the grippers of the tongs located one above the other.

FIG. I shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

The device comprises a frame 1 with guides 2 on which the carriage 3 is located. On the base 1 there is installed 10 water 4 with a screw 5 for moving the carriage 3 by means of a nut 6 mounted on it. In the carriage 3 there are shanks 7 and 8, the upper ends of which have grips 9 and 10, and on the lower rollers 11, 15 and 12 are fixed. On the bed 1 there are installed double-sided additional guides 13 and 14 along which the rollers 11 and 12 of the bolts 7 and 8 move. The guide 13 is provided with a clamp 15, which is pressed to spring 16 the stop 17, and the guide 14 is equipped with a slide, which springs oh 19 is pressed against the support 20. Springs 21 and 22 are mounted on the rod 7, and springs 23 and 24 are mounted on the rod 8. Springs 21 and 22 are fixed on the rod 7 by projections 25 and 26, and springs 23 and 24 are fixed on the rod 8 protrusions 27 and 28. The device is equipped with end sensors 29 and 30. The dotted line indicates the initial position of the carriage 3.

The device works as follows.

When the actuator 4 is turned on, the screw 5, which interacts with the nut 6 of the carriage 3, begins to rotate. The carriage 3 moves from the initial position along the guides 2 together with the shafts 7 and 8. At the same time, the rollers 11 and 12 run over the slides 15 and 18 and the roller 11 rises along the inclined surface of the slits 15 onto the upper plane of the guide 13, and the roller 12 lowers along the inclined surfaces of the slides 18 onto the lower surface of the guide 14.

In this case, the rods 7 and 8 move, and the grips 9 and 10 connected with the rods close, seize the product (not shown) and with the force determined by the springs 22 and 23 move it. Moving the product with the closed grippers continues until the rollers 11 and 12 reach the end of the guides 13 and 14. Reaching the end of the guide 13, shtanga 7, lost support, under the action of the spring 21 moves down, and the rod 8 under the action of the spring 24 moves upwards. The grippers 9 and 10 are then unfolded and release the product, and the rollers 11 and 12 change places with respect to the plane of the guides 13 and 14.

After the clutches are disengaged from the end of the product, the device can work as a push-up device and sends the products flush to the socket in the desired direction.

When the carriage 3 approaches the sensor 30, it actuates and reverses the actuator 4, the screw 5 reverses the direction of rotation and the carriage 3 together with the rods 7 and 8 and the grippers 9 and 10 return to their original position.

When reversing, the rollers 11 and 12 deflect the slides 15 and 20, which, after passing the rollers, return to their original position by the springs 16 and 19.

The carriage reversal is carried out before the sensor 29, which switches the actuator 4 to a forward stroke, after which the operation cycle is repeated.

The device ensures the cyclical feeding of long products, increases labor productivity and allows to automate the assembly process.
