JPS5964458A - Entanglement preventive construction around roller at supply hole of thin film conveying device - Google Patents

Abstract

PURPOSE:To prevent entaglement of a film around a guide roiler at the supply hole of a conveying device for films to be used in packaging foods, by furnishing the roller at its periphery with two or more ring-shaped grooves and by fitting each guide comb of a fixed comb member in said grooves in such a way as protruding to the outgoing side. CONSTITUTION:Ring-shaped grooves 51 are formed at the periphery of brake rollers 4a, 15a, and comb members 52, 54 are fixed on the incoming side of the rollers 4a and 15a being supported by their respective frames and a supporting frame 13, where guide combs 53, 55 of these comb members 52, 54 are inserted in such a way as passing in the ring-shaped grooves 51 and protruding to the outgoing side of rollers 4a, 15a. When the film supply hole P is shut, the guide combs 53, 55 of the comb members 52, 54 separate from each other to face each other. The leading edge of the film for packaging F is transported between guide combs 53, 55 being pinched by the rollers 4a, 15a at their outside surfaces, in which there is no risk of entangling round the rollers 4a, 15a because said leading edge is checked by guide combs 53, 55.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for inserting traps into the packaging section of a seven-fold strip-shaped packaging film, for example, in a packaging machine for perishable products.

The edges of the strip-shaped packaging film in the width direction 1II11 are sandwiched between a pair of upper and lower endless bells on both sides of the packaging section, and the upper and lower edges 1111
It is well known that one belt of film is conveyed to the packaging section. In this case, in the preparation stage of the packaging operation, the starting end of the packaging film is inserted into the film feeder to set the packaging film, and then the conveying device is operated. When the machine is in operation, the starting end of the packaging film has a single force brake roller (patent application 1986-18
7522 (corresponding to 4 and 15)), the unloading side force and the force from the outside of the brake roller sometimes wound up.

The object of the present invention is particularly to provide a horizontal movement which completely prevents the winding around the roller.

First of all, let us explain the details of the present invention when it is used in a conveyor device equipped with a width belt @ prevention (re-pox) and a packaging machine for good products. A packaging film conveying device installed at the top, shown in Fig. 1.2 VC7J.

The above-mentioned VC subJ2 is loaded onto the loading device 1, and the packaging film F2 is set from one of the pair of take-up rolls 41 provided on the left side of the machine. In this case, the operation bar 28? ]l-operation to adjust the position of the moving frame 27 according to the width dimension of the packaging film F. Then, as shown in FIG.
The instep rotates upward, and the upper rollers 1B and 29 and the lower rollers 18 and 29 are separated and the film supply port P is opened.
opens. From this state, the starting end side of the packaging film F of the take-up roll 41 is guided through the circumferential rollers 1113 and 4 to the supply port P [and placed on the lower round shells 1-213, 23, and 33. Next, the opening/closing frame 12 is brought closer to the upper rollers 18, 29 and the lower rollers 1B, 29 by 1000 km, and the film supply port 1' is closed.

When the conveyance device 1 is driven by the awn, the starting end side of the packaging film F located at the supply port P is conveyed toward the packaging section S at the center of the conveyance device 1. On the way, the saw blade 44 shown in FIG. 1 moves upward instantaneously to cut the packaging film F to a certain length [1111! ! A perforation is formed in the direction, and the packaging film F held between the upper and lower roller shafts 15, 4 is pulled by instantaneous flaking on the roller 1III 114, and this tensile force causes the film to be cut at the perforation. The package is then transported to the packaging section S1 at 1:9, as shown by the phantom line in FIG.

In synchronization with this conveyance operation, as shown in FIG.
will be placed on.

The packaging film F on the packaging section S is held by the front decoy pressing member 26.
It is clamped by the upward movement of 36.

Although not shown in the figure, when the packaging film is set, the pedestal 43 is moved upward and the article W is pushed to the VC packaging position as shown by the imaginary line in FIG. is moved downward, and a folding operation of the packaging film F is performed on the lower side of the item W. Then, the item W is wrapped in the packaging film F as the upper side is fully folded. The wrapped item is carried forward to the WB, and the next process of packaging is performed in the same manner.

The above is an outline of the conveyance device and its related parts. During this wrapping operation, a part of the starting end side of the packaging film F is transferred from the delivery side of the brake rollers 4a and 15alN of the N rollers 1lill14 and 15. It may wind around one outer periphery (2), and a structure for preventing this winding will be explained below.

outer periphery 111 of rollers 4a and 15a for
4 has an annular groove 5 extending in the circumferential direction as shown in Fig. 4.5.
The mantissas are formed so that they are parallel to each other in the axial direction. A knob 52 is provided on the inlet side of one brake roller 4a.
As shown in Fig. 2.3, the rollers 15a and 17) for the other brake are installed on the two sides of the two circular frames, and an oak member 54 is also supported on the loading side as shown in Figs. 2-3. Frame 1
3, and as shown in Fig. 3.4.5, each guide comb member 53.55 of these comb members 52.54 follows the annular groove 51 and protrudes toward the N roller 4a, 15a 17) delivery side. It is inserted like this. And film supply port P
When closed, the guide tabs 53, 55 of the tabs 52, 54 are opposed to each other with a slight distance from each other, as shown in FIG.

The starting end side of the packaging film F is this guide grip part 53.55.
It is conveyed through the gap between the rollers 4a and 15a while being held in the outer periphery of the rollers 4a and 15a, and at that time, it is blocked by the guide gripping portions 53 and 55, so that the rollers 4a and 15aK do not wind up.

Note that one brake roller 15a [in the case of the fourth brake roller 15a]
As shown, a similar annular shoulder 56 of narrower width is formed between each annular shoulder 51. This annular groove 56 prevents the wrapping of the packaging film F to the roller 15a as much as possible.
/) to reduce its outer circumference bx. This roller 153↓ is made of metal, and the other brake roller 4a is made of rubber.
Both the jtl rollers 4a and 15a may be formed of combs.

Further, the comb member 52 corresponding to one of the brake rollers 4a is formed with a groove 57 in which the saw blade 44 cuts when it moves upward, as shown in FIG. 3.5.6.

Further, in the embodiment, two brake rollers 4a are used.

Although this is an example of application to 15'a, it can also be applied to a guide roller for a simple supply port, and of course, one core may be used for only one kite roller.

As described above, the present inventor has provided annular grooves 51 extending in the central direction between the outer peripheries of the rollers 4a and 15a for guiding the film A=i at the film supply port J)v and parallel to each other in the axial direction. In this annular groove 51, a plurality of VCs are formed, and in this annular groove 51, the rollers 4a, 15a (1) 1g have a fixed foot-like one line structure.
This has the effect of completely preventing the wrapping film F from wrapping around the rollers 4a and 15a.
