Description

Presses with turret tables are known, in particular presses for forming silicate bricks, subsequent removal of articles from the table and transferring them to a transporting device. These devices for automatic removal of products are equipped, as a rule, with rotary pullers with clamps of known construction, the principle of action of which is that the molded products are removed from the revolving table using a special gripping element and transferred to a press conveyor located at the press. or na any other transport device.

Each rotary cycle is subdivided into translational and reverse movements of the gripping element. The rotary puller is driven by a gear-rack mechanism and a pneumatic or hydraulic cylinder. The working speed of the removable device must correspond to the working speed of the turret press.

Such a design of the device regulates the speed of the press due to the fact that with an increase in the working speed in the process of shooting and transferring to a transporting device, there is a danger of destruction of products that have little strength.

In the proposed device, the revolving table is simultaneously removed and transferred to a transport device located at the press of several products at once.

Structurally, this is ensured by the fact that above the press table, a vertical reciprocating magazine is mounted, having one or several chambers mounted above the co, corresponding molds. In the chambers there are grips, for example pneumatic, for holding articles, and the puller is made with a rotary device in the form of pivot-lever triangles. One of the levers of the triangle is connected to the other with the possibility of movement by means of the scenes. On the second lever of the hinged triangle triangles, the clamping brackets are loosely seated. When turning the hinged triangle, the movement of one of the levers is limited by the stop.

FIG. 1 shows the proposed device top view; in fig. 2 - the same, side view.

On support 1, located above the press table (shown in dotted lines in the drawing), a shop 2 is installed, which plays the role of a puller. The magazine, in synchronization with the rotation of the press table, moves up and down using a hydraulic or pneumatic cylinder 3. The number of chambers 4 in the magazine 2 corresponds to the number of products molded during one pressing cycle. On both longitudinal sides of the chambers 4 there are adjustable pneumatic or hydraulic stops 5 having an elastic lining. Instead of these stops 5, so-called air pads can be used. When the magazine 2 is moving downwards (the command is supplied from an electrical contact sensor, not shown in the drawing), in direct dependence on the rhythm of the press, the stops 5 (or air bags) in the chambers 4 are opened. As a result, the internal dimensions of the chambers 4 increase. Upon further downward movement of the magazine 2, it slides over the formed articles located on the press table and captures them. After the product is in store 2, the stop 5 (or air bags) is closed and the internal dimensions of the chambers 4 are reduced, the products in them are clamped with the force allowed by the strength of the products. After this, the magazine 2, together with the products in it, rises again, making room for new products — the table rotates and the next pair of products enters the shop 2. When the shop moves downward (described above), the products in it that open the stops or the airbags 5 are again lowered onto the following articles to be removed. The store, without delay, drops below, seizes new products and raises them up with the products already in it. These movements of the magazine are repeated until each of its cells picks up several finished products.

The products are then grasped by clips 6, reinforced with the possibility of rotation on the hinged triangles 7, and transferred to the transport device installed at the press. For the case when the flat pressed products in the magazine are placed one on another at the edge, it is necessary to turn them in the process of nepeHQca to the required angle.

The levers of the triangles 7 are driven by pneumatically (or hydraulically) acting central cylinder 8 equipped with toothed rails 9. The toothed rails of the central cylinder 8 are coupled with the toothed segments 10 rigidly connected with the guiding levers //. Levers // // and the toothed segments 10 are fixed on the axis x 12, taking into account the possibility of rotation. Due to such a constructive solution, the number of binding elements is minimized. The treated products are installed on the transport device in parallel rows IS. This is done as follows: the lever arm 14 moves along a trajectory determined by the adjustable position of rigidly fixed stops 15, while the levers of triangles 7 with clamps 6 perform more rotational movement around the resulting centers 16. Points 17 18 wings of triangles 7.

Subject invention

A device for automatically removing articles from a table, preferably a turret press, and transferring them to a transport device, including a rotary puller with clamps, driven by a rack-and-pinion mechanism and a pneumatic or hydraulic cylinder, characterized by that, in order to provide simultaneous capture of several products, turn them on the edge and install in parallel rows, a vertical reciprocating magazine is mounted above the press table, having one or more chambers mounted above the respective molds, in which the grippers are located, for example pneumatic, for holding the products, and the puller is made with rotary devices in the form of pivot-lever triangles, one of the levers of which is connected with the possibility of or using Telis with another, which freely planted clamping brackets; moreover, when the articulated triangle is rotated, the movement of one of; its leverage is limited to stop.
