DESCRIPTION:
BRIEF SUMMARY
The invention relates to a device for packaging products, in particular bread, in bags, at least comprising feed and discharge means for the products, the feed means conveying the products at a level above the discharge means, a bearing guide extending essentially at right angles to the direction of conveyance of the products, for guiding a bearing part which can be driven in a reciprocating movement by a rotary drive motor by means of a main linkage assembly and bears a lower and an upper scoop, which scoops can be moved relative to each other during and as a result of the movement of the bearing part, the device being able to place a bag over a product to be packaged by means of the scoops mounted on the bearing part, while the product is retained by blockade means, and the lower scoop having a supporting surface which, at least during the infeed of a product to be packaged on the supporting surface, is inclined downwardly, viewed in the direction of conveyance of said product.
The bags which are used for packaging the products can be conventional bags which are open at one side, but it is also possible to use sleeves which are open at two sides and are cut from, for example, a hose-type material, the ends of which sleeves can be closed at a suitable moment.
Such a device for packaging products such as, for example, bread, is known from U.S. Pat. No. 3,451,192. In the case of the device described therein the lower and the upper scoop move into a bag which is being held open. Through the scoops moving apart the bag is stretched around front sides of the scoops. At the same time, the product to be packaged is placed by the feed mechanism on the part of the supporting surface of the lower scoop situated at the rear side. The supporting surface of the lower scoop in this case lies in the crosswise direction at an angle of 15.degree. with the horizontal. The bag is pulled over the product to be packaged by moving back the bearing part, while a separate blockade part retains the product, and the packaged product falls onto a bottom plate which, like the scoops, is disposed in an inclined position. When the scoops are moved fully out of the bag, a pusher mechanism moves the packaged product from the inclined bottom plate onto the discharge means.
This had the disadvantage that a separate pusher mechanism is necessary for placing the packaged product on the discharge means. Problems also occur in the packaging of sliced bread when the lower scoop is being withdrawn from under the bread. Since, on the one hand, the loose slices do not begin to fall simultaneously and, on the other, they fall onto an inclined bottom plate, movements of the slices relative to each other occur, resulting in crumbs forming and the slices falling out of formation. Besides, at a subsequent stage the bread has to be tilted in such a way that it comes to rest in a horizontal position, which necessitates additional facilities, and increases the risk of further damage.
The invention eliminates these disadvantages by providing a device according to the preamble, in which the discharge means comprise an essentially horizontal conveyance face extending to just below the lower scoop, the two scoops are hingedly connected to the bearing part, and the device is provided with a tilting unit which is designed to turn the two scoops in such a way that the supporting surface is in a horizontal position when a bag has been placed over the product and the scoops move out of the bag.
It is advantageous if the feed and discharge means each can be placed at either side of the device with the result that the direction of conveyance can be reversed, and the tilting unit is adjustable, so that in the case of both directions of conveyance said unit can turn the supporting surface into a horizontal position during the placing of a bag over the product to be packaged.
In this way, one device will suffice for both directions, while in conventional devices for packaging products a separate construction of the device is necessary for each of the two possible dire
