Description

2. The device according to claim 1, which is, in that, with the compensation of thickness variations of 1100088.. l and - it is equipped with a compensating element in the form of a free-moving product, on the shaft of a spring-loaded rail.

The invention relates to presses for the production of non-metallic sheet materials, for example plywood.

A device for unloading is known, made, for example, in the form of movable and stationary legs, which form clamps and -click on the edge of the sheets of plywood when the latter are removed from the interplate spaces after opening the press.

. The movable legs in them are attached to a vertical rod of the pusher, which has the possibility of axial movement for closing and opening ij.

The movement of the rod in such a device is carried out by a separate hydraulic or pneumatic cylinder, which complicates the control of the press and creates inconvenience in maintenance.

It is also known a device for unloading articles from an external press, including an unloading stand, a pusher with a shaft, and a gripping device zj.

The disadvantage of this device is the presence of a special actuator Dp creating a clamping force, which would ensure reliable holding due to the forces of friction between the product and the arms-grippers.

The purpose of the invention is to simplify the construction, increase reliability and compensate for the different thickness of products.

The goal is achieved

that in the device for unloading articles from the floor press, the gripping device is made in the form of eccentric cams, with horizontal rods mounted on the puller, which are kinematically connected with eccentric cams, and stops are mounted on the discharge stand.

The device is provided with a compensating element in the form of a spring-loaded slider freely moving on the shaft.

FIG. 1 shows a schematic view of the unloading device, side view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. 1 (front view); in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a section of YYD in j of FIG. one; in fig. 6 is a view of D in FIG. The device is mounted on the pusher 1 of the stack (conventionally not shown) having means for moving to and from the press. In the upper part of the pusher, the device includes horizontal rods 2, fitted with fixed cone bushings 3 associated with them. In addition, at their ends each rod 2 carries adjustable nuts 4 interacting with the stops 5 and 6 of the stack, depending on whether the pusher moves to the press or From him. The bar is installed in the slide supports 7 and 8 and through the taper bushing 3 can communicate turning movements in opposite directions within the angle of a pair of vertical shafts 9, for which the latter are equipped with levers 10 and 11 with rollers 12 fixed at their upper ends.

To return the shafts to the position, springs 13 are provided, attached to these shafts by bolts 14 and 15 with shaped heads.

The shafts 9 are provided (according to the number of floors of the press) with fixedly mounted gears 16, interacting with the laths-sleeves 17, which are free to sit on the shafts 18, made integral with the other rails 19, cut from two sides of the shafts.

The slats 19 engage with shaft-shafts 20 and 21 mounted by their shanks in rack 22. Eccentric cams 23 and 24 are rigidly mounted on shanks to grip and unload sheets 25 from the press.

On the shafts 18 are also provided springs 26, pressed by nuts 27,

The device works as follows.

At the approach of the pusher 1 to the extreme 5 forward position (relative to the press), the rods 2 are pressed by the support 5 to the right, the slides in supports 7 and 8. The conical bushings 3 at the same time turn the levers 10 and 11, and with them 10 and the shafts 9 by an angle ot, rotating the gears 16. The gears move the rails 17 to the right, and they, through the springs 26 and nuts 27 on the shafts 18, move them also to the right, from which they come in the rotation of the gears 20 and 21 (through the rails 17). The latter provide for the eccentric cams 23 and 24 to grip sheets of material 25, previously pushed out of the press by any device by an amount f.

When there are deviations in the thickness of the product, when the grip on one floor occurred earlier than on others, the rotation of the eccentric cams on this floor 25 stops and the rail 17 moves along the shaft 18, compressing the spring 26.

After unloading items from the press, which is carried out by moving the pusher 1 away from the press and when it (the pusher) approaches the extreme position, the rod 2 is pressed by the support 6 to the left, the springs 13 by the bolts 14 and 15 rotate the shafts 9 in the opposite direction. The tapered sleeves 3 are displaced to the left by the rods 2, not obstructing the rotation of the shafts 9.

The shafts 9, rotating through the described rack-and-pinion gears, eccentric cams 23 and 24 are set apart, the products are released. The beginning and end of the interaction of the cams and the material of the products is governed by nuts 4.

The absence of a separate drive for capturing products simplifies the management of unloading mechanics, allowing for reliable tight coupling between the position of the pusher relative to the unloaded products and the closing of the grippers. Since the capture of products occurs when the pusher is idling (movement towards the press), an increase in the drive power of the displacement by an amount necessary for closing the grippers is not required.
