Device for topping pastries

The invention relates to a device for topping baked goods by introducing pastry-like masses, such as butter, cheese, sausage and the like, into the baked goods.

Sandwiches, rolls and other items play an important role in the range of products offered by bakeries and other shops. Up to now, these have been prepared by hand, whereby the topping of the baked goods requires that they are first cut open, then spread with the topping and put back together again. This procedure also applies when it comes to offering pretzels with butter as is customary. Cutting the baked goods is also the usual preparation, which is quite labor-intensive and also involves the risk of injury from handling a knife.

It is the object of the invention to propose a device which is able to top the said pastries without first cutting them.

This object is achieved according to the invention by a device with injection needles which are arranged on a needle holder and

are connected to a device for the cyclical supply of the topping mass into the needle cavities, whereby the injection needles can be inserted into the baked item fixed on a carrier and the mass can be pressed into the baked item via the needles. The injection needles are arranged in a plane parallel to the carrier plane so that the mass introduced into the baked item is distributed in one plane, i.e. as with conventionally topping baked items.

In order to enable the device according to the invention to be adapted to the respective shape and size of the baked item to be covered, the needle holder can be adjusted parallel to the horizontal plane of the carrier and vertically. The positions of the free ends of the injection needles can also be changed by axially adjusting the injection needles in the needle carrier and adapted to the external configuration of the baked item.

In a preferred embodiment of the device as a semi-automatic device, the carrier can be designed as a cyclically rotatably driven carousel with compartments for each receiving a piece of pastry, with each compartment being assigned a slider with which the piece of pastry in the relevant compartment can be pushed radially to the edge of the carousel into a position in which the piece of pastry can be fixed by a hold-down device and in which injection needles can be moved into the piece of pastry by adjusting the needle holder.

The slides can be pre-tensioned radially towards the centre of the carousel with a spring and rest with the ends of a slide rod against a fixed cam disc, so that the slides, depending on the rotational position of the carousel, are in a reset position in which the respective compartment is ready to receive

of a piece of pastry is open, or in a pushed-forward position, with leaf springs engaging the sides of the piece of pastry in each compartment being assigned as guides for the piece of pastry to be pushed into the above-mentioned position. Finally, a flap can be provided on the bottom of each compartment, which can be mechanically controlled into a closed and open position when the carousel rotates.

The invention is explained in more detail below using an embodiment shown in the drawing.

Fig. 2 is a side view of the device according to Fig. 1,

Fig. 4 is a side view of the injection unit according to Fig. 3.

The device consists of a feed unit 1 and an injection unit 2. Both units 1 and 2 have a common frame 1.1, which is preferably designed to be movable on rollers. Approximately at table height there is a round carrier 1.2 for the baked goods 3 to be treated, which rotates in cycles around a vertical axis 1.3. The carrier is driven by a motor 1.4 of a suitable design.

The carrier 1.2, designed in the manner of a carousel, is divided into compartments 1.6 on its supporting surface by radially extending webs 1.5 for each of which one piece of pastry 3 is accommodated. Each compartment

· · ··· m mm

1.6 is assigned a slide 1.7 which is mounted in a suitable manner by means of a slide rod 1.8, which is supported with its inner end on a frame-fixed, centrally arranged cam disk 1.9 under the pressure of a spring 1.10.

The outer boundary of the compartments 1.6 is formed by a stationary border 1.11, which consists of two round rods arranged one above the other at a distance. In the area between the border 1.11 and the slide 1.7, the carrier 1.2 is provided with a flap 1.12 for each compartment, which can be controlled into a closed or open position depending on the circumferential position of the compartments 1.6, in which the flap 1.12 is in the plane of the carrier 1.2 or forms an opening in the carrier 1.2. The corresponding control of the flaps 1.12 is preferably carried out mechanically, for example by a curved rail 1.13 fixed to the frame that guides the flaps 1.12. Finally, the compartments 1.6 are equipped with leaf springs 1.14 for laterally positioning the baked goods 3.

For the sake of simplicity, only three compartments and the parts associated with them are shown in Fig. 1. It goes without saying, however, that the compartments and the parts associated with them are distributed over the entire support surface.

The injection unit 2 is attached to the side of the frame 1.1. It comprises a set of injection needles 2.1, which are releasably secured next to one another in a needle holder 2.2 at a distance. The needle holder 2.2 is guided by means of guide bolts 2.3 in bushings 2.4 fixed to the frame and can be moved by a working cylinder 2.5 in a horizontal plane and radially to the carrier 1.2. The injection needles 2.1 protrude with their free ends from the frame side.

the needle holder 2.2, whereby they lie in a plane parallel to the carrier plane. The injection needles 2.1 can be changed by axial adjustment in the needle holder 2.2 with regard to the position of the free ends and can thus be adapted to the external configuration of the baked goods 3. The injection needles 2.1 are fastened on the other side in a distributor head 2.6, whereby their cavities open into the distributor head 2.6. This is connected via a hose 2.7 to a suitable storage container for receiving the mass to be introduced into the baked goods 3, from which the mass can be dispensed in doses.

If the hose is long enough, it allows the needle holder to be adjusted relative to the carrier and the storage container.

When the motor 1.4 is activated to drive the carrier 1.2, it is rotated in cycles at an adjustable cycle time according to the angular division of the individual compartments 1.6, e.g. clockwise. The baked item 3 is placed in an empty compartment 1.6 in a loading field comprising two to three compartments and is deposited on the carrier 1.2 or the flap 1.12 and centered laterally by the leaf springs 1.14. As the carrier 1.2 continues to rotate, the slide 1.7 is increasingly pushed radially outwards via the cam disk 1.9, thus forcing the baked item 3 against the edge 1.11. The baked item 3 has thus arrived in its alignment position and is thus conveyed into the area of the injection unit 2. There, a pneumatically operated hold-down device 2.8 is first lowered onto the baked item 3 so that it is now firmly clamped in its position. The arrival of a baked item in front of the injection unit 2 is registered by a reflex light barrier 2.9, whereby the air cylinder 2.5

is activated to insert the injection needles 2.1 into the pastry 3.

After reaching its end position, the mass is dispensed in a metered manner from the storage container containing the mass to be injected, which spreads out in one plane in the baked item 3 thanks to the arrangement of the injection needles 2.1. After the injection needles 2.1 and the hold-down device 2.8 have been re-controlled, the filled baked item 3 is guided out of the area of the injection unit 2 by turning the carrier and is dispensed downwards from the device in one of the next cycles by opening the flap 1.12.

The injection needles 2.1 can also be arranged one above the other in two parallel planes, for example. The needle holder 2.2 can also be adjusted vertically to allow adaptation to the height of the respective baked item 3.
