Description
RING SUPPORT FILM FOR HORIZONTAL MACHINES
«* WRAPPING WITH FLEXIBLE FILM OR PACKERS, AND A METHOD TO PRODUCE THE RINGS. FIELD OF INVENTION 5 The present invention relates in general to film wrapping machines or packers, and in particular to a new and improved film support ring, for use in horizontal flexible wrapping machines or balers, and a method
to produce the rings. BACKGROUND OF THE INVENTION Packing or film wrapping machines are of course well known, and comprise two different primary types of machines. A first type
Primary wrapping machine or film wrapping machine is the vertical type wrapping or wrapping machine, wherein an annular member, on which a roll of flexible film wrapping material is mounted by a suitable support having a dispensing mechanism or assembly
built-in tensioner, rotates around a vertical axis. The annular member, as well as the support, the roll of flexible film wrapping material, and the spout and tensioning mechanism of the flexible film mounted on the annular member, are in turn mounted on a frame member
Vertical reciprocal which, in turn, is movably mounted on and within a fixed structural frame. Therefore, when it is desired to wrap an article to be packaged or wrapped, where the article is arranged, for example, in a fixed envelope station defined within the fixed structural frame, the annular member rotates in an essentially horizontal plane and with respect to its axis vertical, while simultaneously moving in the vertical direction by means of the reciprocal vertical frame member, so that roll of flexible film wrapping material, mounted on the rotating annular member by the support assembly, completely surrounds and envelops the article in the packaging material or film wrapping. The second primary type of film wrapper or wrapping machine is the horizontal type wrapping or wrapping machine, where these machines are often used for wrapping or packing, among other types or items that are desired to be packed or wrapped, loads essentially elongated that would otherwise be difficult to wrap or pack using the type of vertical wrapping or wrapping machine. In the horizontal type wrapping or wrapping machine, an annular member, on which a roll of flexible film wrapping material is mounted by a suitable support having a spout mechanism or built-in tensioner assembly, rotates about a horizontal axis. The annular member is generally axially stationary, and a first conveyor belt is operatively associated with it, to move the article to be wrapped through the open inner portion of the annular member which thus in effect defines a wrapping station. Accordingly, when the roll of flexible film material, mounted on the support, rotates around the annular member as a result of the support or the annular member rotating about the horizontal axis of the annular member, the wrapping material surrounds the article and part of the first conveyor belt. The first conveyor belt continuously moves the article through the wrapping station defined by the annular member, and the downstream end of the article to be wrapped or packaged is transferred to a second conveyor belt that finally and effectively removes the wrapped or packaged item from the wrapping. the first conveyor belt, and the flexible film wrapping material is released from its wrapping position with respect to the first conveyor belt and effectively shrinks, due to its elastic memory, in a tensioned state on the article, for thereby wrapping or properly pack the item. Wrapping or wrapping machines of the horizontal type are exemplified by U.S. Pat. 4, 953,336 issued September 4, 1990 to Lancaster, III et al., U.S. Pat. 4,553,374 issued November 19, 1985 to Lancaster et al., U.S. Pat. 4,549, 388 issued October 29, 1985 to Lancaster, U.S. Pat. 4,524,568 issued June 25, 1985 to Lancaster et al., U.S. Pat. 4,317,322 issued March 2, 1982 to Lancaster et al., And US Patent 4,110,957 issued September 5, 1978 to Lancaster et al. In relation to the manufacture or manufacture of the annular members of horizontal wrapping type wrapping machines, conventionally the annular members are manufactured as ring members or components which are cut from essentially large, flat, smooth and square-shaped sheets or plates. A typical conventional annular film support for use in wrapping or wrapping machines with horizontal flexible film, and manufactured or manufactured according to the aforementioned technique, is illustrated, for example, in Figures 1 to 3. The ring The film support is generally indicated by the reference numeral 10, and can be seen to comprise an annular member 12 around the outer periphery, on which a reinforcing flange member 14 was welded. The annular member 12 was cut from a essentially square steel plate 16, which is indicated in dotted lines simply for purposes of illustration and understanding of manufacturing and manufacturing techniques, and therefore, it can be immediately appreciated that as a result of the cutting and removal of the annular member 12 of the steel plate 16, corner regions 18 of the steel plate 16 are totally wasted, as well as the central region 20 resid It is important to note that the reinforcing flange member 14 is welded on the outer periphery of the annular member 12 after cutting and removing the annular member 12 from the steel plate 16. In addition , a first annular region, such as that illustrated in Figure 11, of the annular member 12 is provided with a plurality of openings 22 in which fasteners, not shown, can be installed to mount the supporting material assembly of wrapping film, also not shown, on the annular member 12, and a plurality of openings 24 are provided within a second annular region, located diametrically opposite the first annular region, in which additional fasteners, not shown, they can be installed to mount a suitable device or mechanism on the annular member 12 to balance the presence and weight of the wrapping film material holder. Accordingly, there is a need in the art for a new and improved film backing ring which can be used in connection with horizontally wrapped flexible film wrapping machines, which can be manufactured or manufactured quickly and easily and which does not result in the great waste of material characteristic of the annular members of construction, manufacture or conventional manufacture that are used with the current wrapping machines of horizontal type of flexible film. OBJECTS OF THE INVENTION Accordingly, it is an object of the present invention to provide a new and improved film backing ring for horizontally wrapped flexible film wrapping machines. Another object of the present invention is to provide a new and improved film support ring for horizontally wrapped flexible film wrapping machines. Another object of the present invention is to provide a new and improved film support ring for wrapping or wrapping machines with flexible horizontal type film, where its annular member can be manufactured simply and easily without presenting the manufacturing disadvantages characteristic of the members rings of the prior art and their manufacturing or manufacturing techniques. A further object of the present invention is to provide a new and improved film support ring for wrapping or wrapping machines with horizontal type flexible film, where your ring member can be manufactured simply and easily in a very economical way. Another object of the present invention is to provide a support ring for new and improved film wrapping or wrapping machines with flexible horizontal film, where its annular member can be manufactured simply and easily in accordance with manufacturing or manufacturing techniques. wherein the great waste of material characteristic of manufacturing or manufacturing techniques of the prior art is effectively eliminated or substantially reduced. SUMMARY OF THE INVENTION ". The foregoing and other objects are achieved in accordance with the teachings of the present invention, by means of a new and improved film support ring for wrapping or wrapping machines with horizontal type flexible film, where the support ring for new film and The improved embodiment comprises an annular member formed with a steel square profile member having an essentially square transverse configuration. A predetermined section of the square steel profile member is mounted e? a suitable fitting, and the free ends of the square steel profile member are then welded together to form the square steel profile member in an annular steel member.
Subsequently a steel reinforcing plate is welded on the outer periphery of the steel annular member, and a pair of square members are welded on diametrically opposed internal peripheral portions of the steel square profile annular member. One of the square members functions to mount the film roll holder and spout assembly over "the latter, while the other square member functions to mount on it a suitable weight or mechanism for balancing the film roll holder and the BRIEF DESCRIPTION OF THE DRAWINGS Several other objects, features and advantages of the present invention will be better appreciated from the following detailed description, considering it with reference to the accompanying drawings, in which similar reference numerals designate similar or corresponding parts in FIG. the various views, and where: Figure 1 is a raised front view of a conventional annular member of the prior art which is currently used wrapping or wrapping machines with horizontal type flexible film.
Figure 2 is an elevated side view of the annular member of the prior art shown in Figure 1. Figure 3 is a cross-sectional view of the annular member of the prior art shown in Figure 1, taken on the lines 3 -3 of Figure 1. Figure 4 is a front elevated view similar to that of Figure 1, but which nevertheless shows the new and improved annular member constructed in accordance with the teachings and principles of the present invention. Figure 5 is a cross-sectional view similar to
Figure 3, but which nevertheless shows the transverse structure of the new and improved annular member of the
Figure 4, taken on lines 5-5 of Figure 4. Figure 6 is a flow chart showing the process steps of the method used to manufacture or manufacture the new and refined annular member, constructed in accordance with the teachings and principles of the present invention. DETAILED DESCRIPTION OF THE PREFERRED MODALITY Referring again to the drawings, and more particularly to Figures 4 to 6, the new and improved film support ring, constructed in accordance with the teachings and principles of the present invention, and adapted to used in wrapping or wrapping machines with horizontal flexible film, it goes on to be developed and is generally indicated by the reference number 110. It should be noted that in connection with the detailed description of the new and improved film support ring 110 of The present invention, as compared to the conventional support ring 10 of the known prior art, as illustrated in Figures 1 to 3, corresponding parts of the film support rings will be designated by corresponding reference numbers or the like, except that the reference numbers used to designate the various component parts of the ring s of film support 100 of the present invention, will be in series 100. Accordingly, it can be seen that the film support ring 110 of the present invention comprises primarily of an annular member 112 and a reinforcing ring 114 which is welded around the entire outer periphery of the annular member 112 subsequent to its manufacture or manufacture. In particular, as can be seen from Figure 5, the annular member 112 comprises a structural member of tubular shape and which, in effect, has an essentially rectangular or square configuration. The tubular member comprises a structural material of a predetermined length from which a particular section can be cut for use in connection with the manufacture or manufacture of the annular member 112. According to the manufacture or manufacture of the annular member 112, the profile material essentially rectangular or square, after being cut to the axial length particularly desired for use in the manufacture or manufacture of the annular member 112 is mounted within a suitable fitting, which is not shown, and bent to a circular shape, where the free ends of tubular material are welded together to form the annular member 112. Accordingly it can be seen that the annular member 112, unlike the annular member 12 Characteristic of the conventional or prior art annular members used in conventional or current horizontal type flexible wrapping or wrapping machines, is and can be manufactured or manufactured with material in such a way that essentially excessive waste of material is eliminated which characterizes the manufacture or manufacture of the conventional annular members or of the prior art 12 which are disclosed in Figures 1 to 3. Furthermore, the use of square profile as opposed to solid rolls essentially reduces the weight of the resulting annular member, while that the structural resistance of the annular member 112 is not compromised. In order to pr To provide an annular member with additional strength and stiffness and necessary for use as a rotating annular member in the horizontal flexible film wrapping or wrapping machine, a steel bar or plate is welded around the entire outer periphery 123 of the member ring 112 to function as reinforcement ring 114. Further, as can be seen in FIGS. 4 and 5, a pair of brackets or support plates 126 and 128 are welded, having essentially segment configurations as a result of a string portion of edge 119 intersecting an arcuate section 121, to diametrically opposed internal peripheral portions 125 of the annular member 112. The first bracket or support plate 126 is provided with openings 122 for accommodating fasteners, not shown, and functioning to mount the support of film roll and dispensing assembly, which is also not shown, on the square and on the annular member 112 and a second one. The face or support plate 128 is similarly provided with opening 124 for accommodating fasteners, not shown, which function to mount a suitable device or mechanism on the bracket to balance the film roll holder and the spout assembly. It is noted that the brackets or support plates 126 and 128 are welded to the inner peripheral portions 125 of the annular member 112, so that each bracket or support plate 126 and 128 is located at an axially central location between the surfaces b sides front and rear 130 and 132 respectively of the annular member 112. It is also noted that the tubular square profile with which the annular member 112 is made is necessarily essentially square or rectangular in cross section to provide the mounting surfaces on which it will be mounted easily the reinforcing ring 114 and the square plates 126 and 128.
If a profile of transverse configuration, for example circular, was used, attaching the reinforcing ring 114 and the square plates 126 and 128 on the annular member 112 would be somewhat difficult to achieve. "Furthermore, it is also noted that although the method or flowchart of Figure 6 illustrates or manifests the fact that the reinforcing ring 114 is welded to the outer periphery of the annular member 112 before welding the plates or members. of support bracket 126 and 128 on the inner peripheral portions of the annular member 112, the sequence of these manufacturing steps can be reversed.Therefore, it can be seen that in accordance with the principles and teachings of the present invention, a new annular member was revealed and perfected and can be manufactured or manufactured from tubular square profile material in such a way that essentially the excessive amount of material waste formerly characteristic of the manufacture or manufacture of the conventional annular or prior art members that were used in packing machines or wrapping machines with flexible horizontal type film. possible many modifications and variations of the present in light of the previous teachings. Accordingly, it should be understood that within the scope of the appended claims, the present invention may be practiced in other ways than those specifically described herein.
