The present invention relates to a band feeding guide unit of a packaging machine, and more particularly, it is possible to adjust the size of the guide unit arbitrarily according to the specifications of the packaging product so that the size of the packaging machine can be easily changed, and the feeding and banding operation of the packaging band is smooth. The idea is to put together the idea to make it happen.

A packaging machine which binds a conventional packaging article as a band is shown as a partial fracture perspective view in FIG.

This is outlined on the base 102 of the packing machine 101 ( The arch frame 103 of the type is placed, and the metal band guide rod 104 is installed in the recess 103 'of the arch frame 103, but the band guide rod 104 has a cross section. The guide band 104 'of the outline (C) shape is provided so that the packing band (b) can be fed or back fed onto the guide opening 104'. In order to bind the band (b) to the goods to be packaged after the completion of the feeding of the band (b), the band guide section 104 has a driving shaft 105 at a lower side of the band guide section 104 so as to perform a angular movement of a predetermined width. A shaft 106 is fixed to the cap 106, and an actuating lever 108 having a roller 107 connected to the cam 106 is installed so that the actuating lever 108 and the band guide 104 are spring 109. The band guide between the guides 104, spring (109 '), etc. to perform the role of the guide when feeding the band (b) A has a structure that is installed to the other elastic.

The packing machine 101 having a band feeding guide unit for a packing machine configured as described above and binding the band to a product may include a number of problems as described below. Looking specifically at this; a) The arch frame 103 is not made compatible with the size of the packaged products because the packaging machine is made of a limited size of a metallic material. In other words, the economical efficiency is extremely low because it is necessary to have a separate standardized model according to the specification of the product to be packed.

b) As mentioned in item a above, not only the arch frame 103, but also the band guide 104 is also difficult in various product packaging because it requires a standardized dimension, and c) the band guide 104 is In the case of opening / closing operation by angular motion to bind the band (b), of course, both the arch frame 103 and the band guide 104 are made of a metallic material, so that a large amount of metallic noise is generated to create a working environment. There is a deterioration.

d) Also, the packaging band (b) is usually manufactured as a film such as synthetic resin, which frequently causes damage to the band (b) due to mutual friction during opening and closing operation between the band guides (104).

e) And since the binding operation of the band (b) is made at a high speed, if the opening and closing operation of the band guide between the 104 guide is not performed smoothly, the band (b) between the band guide for the binding in the state that is not completely made Since it is separated from the 104, there was a number of problems such as band binding is made in a state where a portion of the band (b) is twisted, causing frequent packaging failure.

Accordingly, the present invention is to disclose a band feeding guide unit for a packaging machine of a novel configuration that can eliminate the above many problems.

With reference to the accompanying drawings, the configuration, operation, effects, etc. of the present invention will be described in detail.

2 is a front view of the packaging machine 1 showing a preferred embodiment of the present invention, Figure 3 is a perspective view of the main portion of the present invention.

The upper part of the base 2 of the packaging machine 1 which consists of box bodies, such as a rectangle, is outlined ( The arch frame 3 is placed in a) shape.

The arch frame 3 is assembled with a right-angle coupling 4 for each vertical joint rather than a conventional monolithic configuration. That is, the vertical, horizontal portion of the arch frame 3 is to be assembled to each other by cutting the separate straight arch frame 3 to the appropriate length.

3 shows the assembly of the arch frame 3 and the right angle coupling 4 in detail.

The arch frame 3 is extruded from a metallic material such as aluminum.

The cross section shows a fitting hole (6) through which the fitting hole (5) which can be fitted with the fitting pieces (5) protruded in the vertical direction of the right-angle coupling (4) is rearwardly penetrated in the longitudinal direction. The fitting opening 7 is fitted with the left and right fitting pieces 5 'of (4).

The front surface of the arch frame 3 has a rectangular cross section of an accommodating degree band (b) and is tapered inward toward the front to form a band guide hole 8 having the front open.

A cover flap 9, which can cover the front surface of the band guide hole 8, is fixed on the arch frame 3 as the fixing member 10. The cover flap 9 is preferably formed of a material having a proper steel wire and elasticity such as urethane.

The arch frame 3 of the above-described configuration is assembled using the right angle coupling 4 in the same configuration on the left and right vertical portions and the upper horizontal portion.

The right angle coupling 4 is preferably formed of a rigid synthetic resin or the like as a constituent member connecting the corner portions.

When the right angle coupling 4 is firmly assembled with the arch frame 3 perpendicularly to each other, the vertical corners connecting the band guide holes 8 may be formed between left and right guides so as to smoothly feed the band b. 11) to form a guide opening 12 consisting of an arc of the corner surface.

And on the vertical connection portion at both ends of the right angle coupling (4) to form a fitting hole (15) that can be fitted with the fitting piece (14) formed at one end of the horizontal frame (13) fixed to the lower base (2) left and right do. Of course, the upper surface of the horizontal frame 13 is coincident with the upper surface of the guide opening 12 of the right angle coupling (4).

The horizontal frame 13 is a partially broken perspective view of FIG. 4, and the other end is firmly fixed to the base 2 in the packaging machine 1, such as a bracket 16, as described in more detail, and a stopper 17 in the longitudinal direction on one side of the upper surface. ) Is integrally formed.

The cross section is roughly spaced apart from the upper surface of the horizontal frame 13 at an appropriate interval (that is, a free space through which the band can be fed). The intermittent cover 18 capable of intermittent band binding is firmly fixed to the upper end of the operating lever 20 pivotally fixed left and right of the driven shaft 19 by a bracket 21.

One of the actuating levers 20 of the actuating levers 20 is provided with a roller 24 which can be in contact with the cam 23 inserted into the driving shaft 22.

In addition, the actuating lever 20 is elastically installed with the gas as the spring 25 so that the intermittent cover 18 can be held in place on the horizontal frame 13 before receiving the operation of the cam 23.

The bracket 21 fixing the operation lever 20 and the intermittent cover 18 is preferably formed to be adjustable as a piece 27 by forming a long hole 26 so that the gap can be adjusted according to the width of the packing band. .

Subtitle 28 in the drawing shows a band guide hole formed between the intermittent cover 18 and the horizontal frame 13. It looks at the operation and effects of the present invention can be configured as described above.

The band b is fed and back fed by known means. That is, the band guide hole 28 between the horizontal frame 13 and the intermittent cover 17, the guide opening 12 of the right angle coupling 4, and the band guide hole 8 of the arch frame 3 are sequentially The band (b), which is fed while passing, pushes the roller 24 connected thereto as the cam 23 on the movement shaft 22 rotates, thereby angularly moving the operating lever 20, and thus the operating lever. The intermittent cover 18 fixed to the other end of the bracket 20 by the bracket 21 is spaced backward from the upper surface of the horizontal frame 13 so that the band b is bound by a known operation, in addition to the horizontal frame 13. The fed band (b), that is, the band (b) fed on the band guide hole (8) on the arch frame (3) is pulled to the front side of the band guide hole (8) by the binding force of the band and band guide hole on the side (8) Binds to a product to spur and wrap the cover flap 9, which has been sealed.

Of course, the band (b) on the band guide hole (8) spurs the cover flap (9) and withdraws to the outside, so that the binding can be performed because the material of the cover flap (9) is made of a material such as urethane having a constant elasticity. This is because only one end is fixed as the fixing member 10 on the arch frame 3, and the other end can be elastically moved to the front of the predetermined width. (See Fig. 6).

Of course, when the binding of the band (b) is completed, the cover flap 9 is rolled back due to the material characteristics, the intermittent cover 18, which was spaced a predetermined width on the horizontal frame 13, the cam 23 and the spring 25 By the action of the recovery will be in the state of separation.

The present invention, which can perform band feeding and binding work while continuously performing the above-described operations, can replace product of various specifications by replacing only the arch frame 3 cut to proper length according to the specification of the product to be packaged. As well as its economic efficiency, it is possible to obtain the ease of installation, compatibility, etc., and to replace it with a material such as cover flap urethane, and its configuration is extremely simple, so that the cost can be reduced and metallic friction noise during work It can be prevented in advance, and it can also remove the factors such as damage to the band and packaging.

The scope of the technology to be protected in the present invention will be mentioned in the following appended claims for utility model registration, but similar infringement aspects such as changing some material configurations and shapes will be included in the present invention.
