CZ300603B6 - Shell frame of vertical packaging machine - Google Patents

Abstract

In the present invention, there is disclosed a load-bearing shell frame (4) consisting of a prismatic jacket (1), outer peripheral stiffeners (2) and inner peripheral stiffeners (3). Both said outer peripheral stiffeners (2) and inner peripheral stiffeners (3) being disposed in an interior defined by the prismatic jacket (1), are attached perpendicularly to all surfaces (7) of said prismatic jacket (1). At least in one of the outer peripheral stiffeners (2) there is performed a service hole with openable and/or removable cover. At least one inner peripheral stiffener (3) is formed by an integral surface that divides the interior defined by the prismatic jacket (1) and the outer peripheral stiffeners (2) into two or several separated portions (5, 6).

Description

Shell frame of vertical packaging machine

Technical field 5

The invention relates to the construction of a shell frame of a vertical packaging machine. The present invention is in the field of technology that addresses machines, apparatus or devices for packaging products or materials.

BACKGROUND OF THE INVENTION

The frame of the vertical packaging machine is a part of the packaging machine, in which the drives and mechanisms are mounted and on which the other devices necessary for the operation of the packaging machine are mounted externally. The switchgear is usually mounted on the frame from the side, in some cases it is inserted into the frame.

The frame must be sufficiently rigid.

Vertical packaging machines are known, the frames of which are designed as castings or welders of thick sheets, which meet the rigidity requirements, but have a high weight and are difficult to manufacture. Also known are machines having drawn frame frames, whether thin-walled steel or solid alloy. These frames have a satisfactory rigidity, but if they are to protect the mechanisms inside the machine, they must be complemented by relatively complex and labor intensive covers, which in addition create a rugged surface, which causes problems in cleaning the machine.

The design of a sufficiently rigid vertical packaging machine frame, simple to manufacture, with smooth outer surfaces that allow easy cleaning and well protects the mechanisms inside the machine, has not been solved yet.

SUMMARY OF THE INVENTION

The object of the present invention is a shell frame of a vertical packaging machine, the principle of which is that the base of the shell frame forms a prismatic shell and circumferential stiffeners are attached perpendicularly to the surfaces of the shell. The prism sheath is formed by three or more surfaces. The outer circumferential stiffeners attached to the edges of the prismatic casing also serve to accommodate doors or removable covers. The inner circumferential reinforcements both increase the stiffness of the frame and can divide the interior space of the frame into two or more parts.

BRIEF DESCRIPTION OF THE DRAWINGS

An exemplary embodiment of the proposed solution is described with reference to Fig. 1, in which is an axonometric view of a shell frame in a five-prismatic shell design with two outer circumferential stiffeners and one integral inner circumferential stiffener.

DETAILED DESCRIPTION OF THE INVENTION

It can be seen from FIG. 1 that the shell frame 4 of the vertical packaging machine is formed by a prismatic casing 1 into which the peripheral stiffeners 2 and one inner peripheral stiffener 3 are perpendicular to all its surfaces 7.

The prism sheath 1 is formed by at least three or more surfaces 7, depending on the shape of the circumferential stiffeners, in this example it consists of five surfaces 7. In some surfaces 7 there are through holes for the outlets of the mechanisms and the ventilation. The outer circumferential stiffeners 2 reinforce the edges of the prismatic sheath 1, and in one outer circumferential stiffener 2 a handling opening with a removable cover is provided.

One or more inner circumferential stiffeners 3 may be formed by a sheet dividing the inner 5 space of the prismatic casing 1 into two or more parts, eg a separate inner space part 5 which serves to accommodate the machine mechanisms and a separate inner space part 6 , which is used to place the electrical components.

The advantage of the shell frame according to the invention is the simple and lightweight construction of thin sheets, thus saving material and labor in production, and further the unitary surface of the frame with smooth walls allowing easy cleaning, while ensuring sufficient rigidity of the frame 4.

Industrial Applicability 15

The invention is applicable to vertical packaging machines, in particular machines operating in wet or dusty environments.
