SU279510A1 - Proofing Cabinet - Google Patents

Description

The invention relates to the field of the food industry, more specifically to the equipment of the bakery industry and can be used in the food industry.

Known cabinet for proofing dough pieces, containing a camera with mounted belt conveyors, one above the other.

However, in a known proofing cabinet containing at least two horizontal belt conveyors placed one above the other, receiving movement from the drive, the structure of dough blanks is deformed and ruled up, the relative position of dough blanks interferes with their transfer from one conveyor to fSpyroK, and it is impossible to adjust the proof time .

The purpose of the invention is to preserve the shape, structure, and the mutual arrangement of the blanks during their transfer from one conveyor to another.

Dd this inside the camera is installed alternately driven in a reciprocating motion of the carriage, on which the belt conveyors are located. At the same time, conveyors adjacent in height are mounted on different carriages.

To ensure a minimum distance between adjacent conveyors in height, they can be supplied with chains fixed on both sides for years: drums and guide sprockets meshed with chains of tapes and forming a bend of their upper arms in the receiving area of dough pieces .

The drive of the carriages is expedient to perform with an adjustable stroke, which provides control of the proof time.

In addition, the cabinet can be provided with a device for changing the distance between the carriages.

In Fig.1, the Mesqui diagram shows the proposed cabinet for proofing dough pieces, a general view; figure 2 - belt conveyor, side view; fig.Z - the same, top view; figure 4 is the same, a section along aa and fcg. 2; ka fig, 5 - the same, in the place of a bend of a tape, side view; figure 6 is the same, the section along BB in figure 5; Fig. 7 shows a device for changing costs between the carriage head.

The proofing cabinet of dough pieces contains a chamber 1, in the lower part of which are mounted the guides 2, along which the carriages 4 and 5 move on the rollers 3. The carriages are driven in

movement from the drive b with an adjustable stroke and are connected with it in 7.

On the carriages, conveyors 8 are laid down with the possibility of movement in the plane of movement of the carriages.

Adjacent in height conveyors 8 are mounted on different carriages and carry straps 9 (see FIG.), On both sides of which chains 11 are reinforced with plates 10.

The ribbon bends around frame 12

(alf gz) drums 13 and 14 and asterisks 15 and 16

(see Figs and 4), mounted coaxially to the drums 13 and 14. Dp tensioning the tape serves as the drum 17, movably mounted on the frame 12.

Guides 18 are mounted on chamber 1 (Fig. 5 and 6), in which plates 19 are movably mounted, the movement and fixing of which is carried out by nuts 20 and screws 21. On plates 19, drums 22, sprockets 23 and 24 are mounted, forming a bend ribbons, with sprockets 24 mounted on the freewheels (not shown). The sprockets 25 (see Fig. 1) are also mounted on the freewheel couplings and are engaged with the chains of the 11 belts 9.

Mobile pganga 26 (see Fig. 7) with nut 27 and pull 28 are mounted on carriages 4 and 5 and provide a change in the distance between them.

Under the upper branch of the ribbons, guides are installed that prevent lateral sagging of the ribbons.

The lower conveyor has a slightly longer length than the opposite, forming a console protruding behind the camera.

The cabinet works as follows.

The carriages 4 and 5 from the actuator 6 receive a reciprocating motion, while the carriage 5 remains stationary, while the carriage 4 performs a double stroke, and with a double stroke of square 1, the carriage 4 remains stationary.

The dough pieces go to the upper conveyor 8 and move with the carriages 4 from the leftmost to the rightmost position. With this, the sprockets 24 and 25, set in motion by the chains 11 of the belts 9, turn in the counterclockwise direction (see Fig. 1).

During the reverse movement of the carriage, 4 stars 24 and 25 are wedged on the free coupling.

course and stopper t chain 11 upper branches of conveyor belts.

The carriage 4 moves relative to the stoning belts, while the dough blanks arriving at the upper conveyor move relative to the carriage 4 by a step equal to the stroke of the carriage, accumulating during subsequent movements of the carriage on this conveyor. At the same time, the workpieces located at the exit of this conveyor are transmitted at the slow speed at the moment when the tape leaves the belt to the lower conveyor 8 of the carriage 5. In the leftmost position, the carriage 4 stops and the carriage 5 begins its cycle of movement.

At steady state operation of the cabinet, all conveyors are filled with dough pieces, and the lower one of the conveyors conveys dough pieces to the furnaces.
