Abstract

The invention relates to devices for feeding flat products, such as cardboard sides to machines for book binding units, and makes it possible to increase reliability of operation. The device consists of a store and a product feed mechanism. The shop includes a movable front and rear walls. On the damper of the front wall is fixed four-lever mechanism. The flap opens automatically when the product is fed. The four-link lever mechanism consists of two pairs of parallel links. Two links are parallel to the front wall, and one of them — the output — is rigidly connected to the wall. The output and kinematically associated links are additionally connected by an elastic link. 1 hp f-ly, 1 ip.

And: the invention relates to devices for feeding flat products, for example, cardboard sides in a machine for KHiDKHhix bindings, and can be used in the printing industry.

The purpose of the invention is to increase the reliability of the device.

The drawing shows a diagram of a device for feeding flat products.

The device consists of a magazine 1 including the front 2 and rear 3 walls, a product feed mechanism movable in the vertical plane of the cutter 5 connected to the front wall by means of a hinged parallelogram containing end link 7 and link 8-10. All links are pivotally interconnected. Link 9 and 10 are parallel to each other, and link 7 and 8 are to wall 2. Angle A is formed between link 9 and horizontal aposkosti. The drawing also shows a resilient return element 11, base 12 and flat products 13. The cutter has a chamfer at an angle B. The elastic element is designed as a rubber ring.

The device works as follows.

In the shop 1, the products 13 are installed. The mechanism 4 pushes the lower one of the action along the horizontal axis, which rests on the shutter 5 of the front wall. Under the action of force, the cutter 5 transmits pressure to the links 8 and 9, which, moving relative to the fixed link 7, raise the cutter 5 to a height sufficient for the passage of the product 13. After passing through the slit the plates 13 under the action of the displacement means and the elastic element 11 (enhances the reliability of the process of lowering) cutoff cuts off the next layer

well, or the book side. Then the feed cycle is repeated.

In the device, parallel links 9 and 10 tons slope to a horizontal plane at an angle of 34-38. With an increase in the angle of more than 38 °, the magnitude of the horizontal movement of the trimmer advances the increase in its vertical movement, which leads to deterioration of the conditions for the withdrawal of products. With a decrease of less than 34, the load on the output product increases significantly. The proposed device allows to display products of different thickness and automate the process of installing the slot to the height of the product, which increases the reliability of the device.

Claims (2)

1. A device for feeding flat products containing a store-mounted store having a front and a rear wall, and a cutter mounted in a vertical plane connected to the front wall, characterized in that, in order to increase reliability of operation, the cutter is connected to the front wall by means of a hinged parallelogram, two parallel links of which are installed vertically, one the link is rigidly connected to the bed, and the other is connected to the cutter, with the other two links of the parallelogram arranged at an angle of 34-38 ° to the horizontal plane in the initial position of the cutter. 2. The device according to claim 1, characterized in that, in order to ensure constant contact with the product, it is provided with an elastic return element, which is connected with an inclined link of the hinge parallelogram.
