Abstract

The invention relates to the field of transport equipment, namely, devices for the piece-by-piece delivery of long products. The purpose of the invention is to increase reliability. The device contains unloading directions, 13, on which the mechanism for gripping the products, made of crank 5 and backstage 6, connected with the slide 7, is mounted. On the guides 13, two shoulders 16 are hinged with counterweight 17 and two shoulders are controlled, and 21 levers associated with the double-arm levers 16 by means of the engagement elements 29 and the fingers 18. The levers 16 are the supports for the products that pull the latter onto the locking mechanism. 4 il. (L

The invention relates to a transport technique, namely, devices for disassembling packs of products (pipes, logs, rods, etc.) and their single issue.,

The purpose of the invention is to increase reliability.

FIG. 1 shows the proposed device, obsh, i view; in fig. 2 - the same, top view; in fig. 3 - node I of FIG. one; in fig. 4 is a view A of FIG. 3

The device consists of two technologically interconnected parts, the bunker 1 and the pre-bunker 2. The latter is structurally a double-chain transverse conveyor of the friction type. The bunker 1 is a double-chain transverse conveyor, the traction bodies 3 of which are supported by special gripping mechanisms 4 consisting of a figured crank 5 and a figured curtain 6, pivotally interconnected by a slider 7. The working surface 8 of the curtain 6 is made along an arc a circle whose center coincides with the swing axis of the backsight 6. There is a slot 9 cut out in the backstage body, in which the slider 7 slides 7. The crank 5 and the wings 6 are hinged on the axes 10 tons of the body 3. On the ends of the axes 10 the carriages 11 are hinged which by Aulus yuschim 12 have the ability to move the gripper mechanism 4. The working surface 8 of the wings 6 are held on the guide 13 under the action of gravity 14. As counterweights width of the device is set two gripping mechanism 4. The guides 13 have a rise in the dispensing direction.

A pair of lugs-mechanisms 15 are installed on the guides 13 of the hopper 1 in the area of the drive shaft of the traction body 3, each of which consists of a hinged two-arm lever 16 equipped with a counterweight 17 to return the lever to its original position and a horizontal finger 18 that blocks the lever 16 in working position by means of a pawl 19 equipped with a counterweight 20 of return, which is rigidly connected with the control lever 21, swinging on the axis 22 and cooperating with the carriage 11 of the gripping mechanism. The double-shouldered lever 16, the pawl 19 and the control lever 21 have respectively limit stops 23 and 24, 25 and 26. The guide bins 1 and the traction chains 27 of the pre-bunker 2, mated with each other by the inclined platform 28, form a single buffer capacity that allows Do not create a significant stock of products. A control lever 21, which is integral with the dog 19, is provided with an engagement element 29 with a finger 18. The hopper 1 and the pre-bunker 2 have individual drives 30 and 31.

The device works as follows.

A bundle of products :: (logs, pipes, rods, etc.) is fed by a crane or any other lifting mechanism to the traction circuits of the pre-bin 2. When the drive 31 of the pre-hopper 2 is activated, the traction chains 27 are driven, Occurring between traction chains and products, the stack of products moves in the direction of the bunker 1. On an inclined platform 28, a partial collapse of the package of products occurs and they are oriented relative to the intersection line of the inclined platform 2 with the guides.

When the drive 30 of the hopper 1 is turned on, the gripping mechanisms 4 mounted on the traction bodies 3 are fed under the stack of products located on the guides. Under the weight of the products, Krivoshisp 5 (Fig. 2) turns about the axis 10 and, acting on the slider 7, causes the slide 6 to rotate. As a result, the gripping mechanism, overcoming the moment created by the force of gravity of the counterweight 14, is set at the top of the guides and, in the recessed position, passes under the stack of products.

At the moment when several outermost bundle items (from one to three) remain in front of Krivoschip 5, the gripping mechanism returns to its original position under the action of the gravity of the counterweight 14, overcoming the gravity of these items and pushes them in front of them to the double-shouldered lever 16, which locked upright by the dog 19. When meeting the products transported in this way with the double-arm lever 16, they stop, and as the movement of the gripping mechanism continues, the products move over the crank and thereby increase recessed shoulder points of gravity of products relative to the axis of the crank attachment. From now on, the gripping mechanism

moves under the products in a recessed position and the two shoulders lever 16 remains locked by the pawl 19 until the point A of the crank 5 is separated from the point B of the two shoulders lever 16 at a distance equal to half the diameter of the maximum log.

The carriage I advances on the control lever 21, unfolds it and the double-arm lever 16 is released by means of the pawl 19. Upon further movement of the gripping mechanism, the crank 5 leaves the last product, released from the gravity of the latter, as a result the entire gripping mechanism opens under the force of gravity of the counterweight 14 and the link 6 enters the gap between the last but one and the last product, separates the outermost of them from the pack and pulls it over the double-shouldered lever 16. The latter under the action of the transported product It moves from one position to another, lockable abutment 24.

The product is then transferred by a gripping mechanism to a subsequent processing apparatus.

After releasing the two shoulders lever 16 from the product, the latter returns to its original position under the force of gravity of the counterweight. The control lever 21, freed from the influence of the carriage 11, rotates about the axis 22 under the action of gravity of the counterweight 20 against the stop 25, while the dog 19 locks the double-shouldered lever 16 in a vertical position, then the process repeats.

As the products are disassembled from the hopper 1, the operator turns on the drive 31 of the pre-bunker 2, and the stock of products in the hopper 1 is replenished.
