Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for manufacturing a package using a foam sheet, and more particularly, the present invention relates to a method for manufacturing a package using a foam sheet, and more specifically to a method for manufacturing a package using a foam sheet. The present invention relates to a method for manufacturing a package covered with a cylindrical foam sheet and an apparatus for manufacturing the package.

Thermoplastic synthetic resin foam sheets have excellent cushioning properties and are therefore used extensively as packaging materials, and various packaging materials have been devised in which tubular objects such as straight fluorescent lamps are covered with foam sheets. There is.

That is, for example, two sheets of thermoplastic synthetic resin foam with the same or different widths and whose long sides are the same length with both ends folded inward or not folded back. A method and apparatus for manufacturing a tube package in which the long sides of the sheet are glued together to form a cylindrical body of a required size to cover the outer peripheral surface of a tube, and the tube is placed inside the cylindrical body (for example, Patent No. 807659
No. 807,660, etc.).

These methods and devices have the advantage that the packaging speed is high and the resulting package itself has a high cushioning effect. On the other hand, however, these methods and apparatuses have disadvantages in that they use a rotating packaging drum as a tube conveying means, which makes the operation complicated, and the structure of the apparatus becomes complex and, therefore, large-sized. The inventors of the present invention have conducted studies to solve the drawbacks of the above-mentioned methods and apparatuses, and have arrived at the method and apparatus of the present invention.

It is an object of the present invention to provide a packaging manufacturing method that is easy to operate and a packaging manufacturing apparatus that is simple in structure, lightweight, and compact.

That is, in the method of the present invention, foamed sheets are supplied from at least two rolls of raw material, and the foamed sheets are passed through two sets of tension rollers, each consisting of a pair of upper and lower rollers, which are arranged opposite to each other. The foam sheet is sandwiched between rollers, and at least one of the upper and lower rollers is rotated intermittently,
The foam sheets are fed downward from the inside of each tension roller, and the lower ends of the two foam sheets hanging below the tension rollers are welded substantially horizontally by a linear heating means, and then the lower ends Made by welding each other 2
The foam sheet is sent downward by the rotation of the tension roller so that the welded end is positioned below the linear heating means, while the tubular object is placed and supported on the hook-shaped mounting body and conveyed downward. Then, the tubular object placed and supported on the mounting body is detached from the mounting body and dropped and supplied in a substantially horizontal state to the bottom of the triangular cylindrical gap between the two foam sheets formed by the welding. Then, the two foam sheets are welded to each other by the linear heating means at the upper end position of the fallen-supplied tubular object, and further melted and cut to form a cylindrical body that envelops the outer peripheral surface of the tubular object. This is a method for producing a package, which is characterized in that a package is obtained in which a tubular object is placed inside a cylindrical body made of a foamed sheet.

In the present invention, a tubular object is a columnar or cylindrical object;
It may be an elliptical cylinder or an elliptical cylinder, or it may have a shape in which holes, grooves, etc. are provided in these pillars or cylinders.

Such tubular objects include, for example, straight tube fluorescent lamps of 10 watts or less, preferably 8 watts or less. The foamed sheet used in the present invention is not particularly limited, but foamed sheets made of thermoplastic synthetic resins such as polyethylene foamed sheets and polypropylene foamed sheets are preferably used.

In addition, the expansion ratio and thickness of this foam sheet vary depending on the weight of the tubular object to be packaged and cannot be absolutely limited.
For example, when packaging a lightweight straight tube fluorescent lamp of 10 watts or less, a polyethylene foam sheet with an expansion ratio of about 20 to 50 times and a thickness of about 0.5 to 2 mm is used. Note that when using a normal foam sheet with a foaming ratio of about 20 to 50 times, the smaller the foaming ratio, the thinner the thickness may be, and the larger the foaming ratio, the thicker the thickness. In addition to the above-mentioned foam sheet itself, the foam sheet in the present invention also includes a laminated sheet in which the outer surface (the side not facing the tubular object) of the foam sheet is coated with a transparent or opaque non-foam sheet. A laminated sheet is preferable because of its high strength. Note that the surface of the non-foamed sheet itself or the surface of the foamed sheet itself may be printed.

The width of the foam sheet (original fabric) (the length in the direction perpendicular to the traveling direction of the foam sheet, which is equal to or less than one) is made equal to or longer than the length of the tubular object to be packaged. In the present invention, the foam sheet is used by folding or not folding so that both end edges (ears) face inward and on the inner surface (facing the tubular object). When using a foam sheet with both edges folded back, the width of the foam sheet refers to the distance between the folds of the folded edges. The method of the present invention will be specifically explained with reference to FIGS. 1 to 6.

1 to 6 are drawings for showing the principle of the method of the present invention. That is, FIG. 1 shows foam sheets 4 and 5.
Each of the two sets of tension rollers 1, 1 and 2,
2, and at least one tension roller on the back of each set of tension rollers is intermittently rotated by an electric motor or the like to supply the foam sheet, and this foam sheet is supplied to the lower part of the tension roller. It is formed by two foam sheets 4 and 5 that hang down from the inside of each of the two tension rollers 1 and 2 and are welded to each other substantially horizontally at their lower ends to form a welded end 3. A triangular cylindrical gap (lacking an upper surface - the same applies hereinafter) 6, a hook-shaped mounting body 7 that reciprocates up and down is in a free state slightly below the upper end of its reciprocating movement, and a nichrome wire or ribbon, for example, is provided. Linear heating means (hereinafter sometimes simply referred to as linear heating means) 8 and 9 each having a linear heating element such as a nichrome strip shown in FIG. FIG. 2 shows that two foam sheets 4 and 5 are fed by tension rollers 1, 1 and 2.2 and their welded ends 3 pass between retracted linear heating means 8 and 9. The above-mentioned mounting body 7 hangs down until it is below the linear heating means, and the above-mentioned mounting body 7 stops at the upper end of its vertical reciprocating motion to show the first step of mounting and supporting the tubular object 10.

At this time, the degree of close contact between the tubular object 10 and the foam sheet can be adjusted by changing the stopping position of the welded end 3. FIG. 3 shows a second step in which the mounting body 7 on which the tubular object 10 is mounted and supported descends toward the welding end 3, which is the bottom of the triangular cylindrical gap 6.

FIG. 4 shows the mounting body 7 that has reached near the bottom of the triangular cylindrical gap 6.
Here, the tubular object 10 is removed from the mounting body 7, and the tubular object 1 is removed from the mounting body 7.
0 indicates the third step in which the material is supplied to the bottom of the triangular cylindrical gap 6 in a substantially horizontal state.

In FIG. 5, the mounting body 7 moves upwards and leaves the triangular cylindrical gap 6, and the linear heating means 8 and 9 move forward and approach each other to spread the foam sheets 4 and 5. A fourth step of welding the upper end of the sandwiched tubular object 10 is shown. FIG. 6 shows that the linear heating means 8 and 9 continue heating the foam sheet 4.
and 5 indicate a fifth step in which the foam is melted and discharged out of the apparatus as a package 11 in which a tubular material 10 is placed inside a cylindrical foam material.

A large number of packages can be manufactured by sequentially repeating the steps from the preparation step to the fifth step. Further, the device of the present invention comprises at least two rolls for supplying the foam sheet and a pair of upper and lower rollers, and the foam sheet is sandwiched between the rollers, and at least one of the pair of upper and lower rollers is rotated intermittently. Then, the foam sheet is sent downward from the inside, and the foam sheet is sent downward so that the welded ends of the two foam sheets formed by welding with the linear heating element are located below the linear heating element 2 A set of tension rollers provided opposite each other, a hook-shaped mounting body for placing and supporting a tubular object, and provided to be able to reciprocate vertically and rotatably, and for causing said mounting body to reciprocate vertically. a mounting body vertical drive mechanism;
a mounting body rotation mechanism for rotating the mounting body when the mounting body receives a supply of a tubular object and when removing the placed and supported tubular object from the mounting body; and the mounting body rotation mechanism; A tubular material supply mechanism that places a tubular material on the body, and a tension roller that welds together the lower ends of two foam sheets that are sent downward by a tension roller and hangs below the tension roller roller. The two foam sheets are welded to each other at the upper end position of the tubular object and further fused and cut in order to enclose the tubular object that has been dropped and supplied from the mounting body into the lower end welded sheet that is sent further downward by the a linear heating element, and two parts, each of which has the linear heating element fixed to at least one side thereof, and which are located outside a foam sheet hanging below a tension roller and are arranged to face each other and to be able to reciprocate in the lateral direction. a support body lateral direction drive mechanism for reciprocating each support body in the lateral direction; This is a package manufacturing apparatus characterized by comprising a package discharge mechanism for discharging the package to the outside. In the foam sheet supply mechanism, the two foam sheets are sandwiched between two sets of tension rollers, and the tension rollers are rotated intermittently by an electric motor or the like to feed the foam sheets, and the foam sheets are fed downward from the lower tension roller. Forced to droop.

The tubular object conveying mechanism is a mechanism that places and supports the tubular object in the upper part, descends, leaves the tubular object in the lower part, and supplies it to the bottom of the triangular cylindrical gap. and means for reciprocating the mounting body up and down, and the mounting body is rotatably pivoted directly or indirectly to the latter means.

The mounting body is a continuous or discontinuous cylindrical body having a notch along its long axis and a hook-shaped cut end face perpendicular to the long axis. Those formed by connecting two or more hook-shaped members of substantially the same shape to each other in a straight line belong to the latter category.

The mounting body is not particularly limited as long as it has a shape that allows the tubular object to be mounted and supported. A cam, an air cylinder, etc. are used as means for reciprocating the mounting body. As the tubular material supply mechanism, conveyors such as a roller conveyor and a belt conveyor, and a chute having a stopper that opens and closes at predetermined intervals at the tip thereof can be used. This stopper may be, for example, a plate or rod that opens and closes the passage of the tubular object by moving up and down or left and right at predetermined intervals, and a plate or rod that is bent at right angles, and the bent point is the boundary in the closed state. One side is kept almost horizontal and the other almost vertical, but in the open state, the bent point is used as a fulcrum to push the horizontal part and lift the vertical part, etc. is used. A time switch or the like is usually used to open and close this stopper. When using conveyors, the tubular objects may be placed on a conveyor that moves continuously at a certain distance, or the conveyor on which the tubular objects are placed may be moved intermittently. good. Note that a hopper or a lift can be provided on the side opposite to the tip (upper side) of each of the chute and conveyor. The foam sheet welding/cutting mechanism has a linear heating means equipped with a substantially horizontal linear heating element, and the linear heating element is, for example, a linear nichrome wire or a ribbon-shaped nichrome strip. The surface of these nichrome wires or nichrome bands may be covered with ceramic or the like.

Therefore, these linear heating bodies can be provided with a groove in a horizontal rod-shaped support and embedded in this groove, or can be attached to the surface of the rod-shaped support without providing a groove in the rod-shaped support. Furthermore, in order to prevent the linear heating element from being contaminated by molten resin, it is possible and preferable to cover the surface of the linear heating element with a film of a heat-resistant material such as fluororesin. Either use two linear heating elements as a set, or omit one of the two linear heating elements and use only a rod-shaped support (the one without the linear heating element is hereinafter referred to as a pedestal). ).
Note that the pedestal is generally made of a heat-resistant material. Note that it is possible and preferable to attach a heat-resistant material such as heat-resistant rubber to the surface of the pedestal facing the linear heating element.
In the former case, the two foam sheets are sandwiched between two linear heating elements, and in the latter case, they are sandwiched between one linear heating element and one pedestal. It is welded by the heated linear heating element and further fused.

The two linear heating elements sandwiching the two foam sheets, or the linear heating element and the pedestal, may both be moved back and forth, or one of them may be stopped at the welding area of the foam sheets and only the other may be moved. It can be moved back and forth.

Although there is no particular mechanism for reciprocating the linear heating element and the pedestal, cams, hydraulic cylinders, air cylinders, etc. are generally used, respectively. In this way, one package containing a tubular object is obtained.

This package is received by the discharging means of the package discharging mechanism and discharged from the apparatus.

Examples of the discharge means include a chute and conveyors such as a belt conveyor and a roller conveyor. In this device, a foam sheet supply mechanism, a tubular object conveyance mechanism, a tubular object supply mechanism, a foam sheet welding/fusion cutting mechanism, and a package discharge mechanism are electrically and/or mechanically connected to each other, and a limit switch and/or a time switch are connected to each other. etc., they are caused to move in relation to each other.

It is supplied by rotating the pieces intermittently by an electric motor etc.
The direction is changed downward by the tension rollers located below each set of tension rollers. Further, below the tension rollers 22, 23, the two foam sheets 20 and 21 are welded to each other almost horizontally, and are further fused and cut. Thus, these two foam sheets form a triangular cylindrical gap.

The straight tube fluorescent lamp 25 passes through the opened stopper 28 and falls in a substantially horizontal state, and is placed and supported on the mounting body 29 of the tubular object conveying mechanism. In the tubular object transport mechanism, the mounting body 29 is connected to the connecting rod 3.
It is indirectly connected to the air cylinder 31 through 0, and reciprocates up and down by the action of the air cylinder 31. Note that the mounting body 29 is pivotally attached to the lower end of the connecting rod 30 so as to be freely rotatable. Straight tube fluorescent lamp 2 mounted and supported by a mounting body 29

are welded to the upper end of the straight tube fluorescent lamp 25 by the linear heating means 33 and 34 of the welding and fusing mechanism, and are further fused and cut. In the welding/fusion cutting mechanism, the linear heating means 33 and 34 are connected to air cylinders 37 and 38 via connection rods 35 and 36, respectively, and are reciprocated in the left and right directions in the drawing by the action of the air cylinders 37 and 38. . These linear heating means 33 and 34
are heated when they move to the left and right in the drawing and approach the foam sheet, and are in a non-heated state when they move to the right and left in the drawing and are separated from each other.The right end of the stroke When it approaches the left edge, it is heated again, melting the attached resin,

The direction of the axis of the spring receiver 41 (the straight line connecting the center of rotation of the rotating shaft 40 and the spring mounting hole of the spring receiver 41) and the direction of the axis of the support rod 43 almost coincide. The direction of the axis of the rotating rod 42 (the straight line connecting the center of the rotating shaft of the rotating shaft 40 and the tip of the rotating rod 42) may be different from the axial direction of the spring receiver 41 or the axial direction of the support rod 43; It is said to be vertical. Further, a contact rod 45 is provided at the lower end of the connecting rod 30 in a downward direction. An upper stopper 46 that contacts the upper edge of the rotating rod 42 and a lower stopper 47 that contacts the lower edge of the rotating rod 42 are provided below the upper end of the vertical reciprocating motion of the mounting body 29 and above the lower end of the mounting body 29, respectively.

That is, the openings of two curved plates 51 and 52, which are formed by bending flat plates into a U-shape, face each other, and the interval between the fold lines is narrower on the foam sheet discharge side than on the foam sheet supply side. Also, curved plate 51
and 52 may be integrally connected. FIG. 10 is a perspective view showing details of an example of the welding and fusing mechanism.

This welding and fusing mechanism has nichrome wires 53 and 54 as a pair of linear heating bodies that reciprocate in opposite directions. Further, the nichrome wires 53 and 54 are arranged in grooves carved in the opposing surfaces of the rod-shaped supports 55 and 56, respectively. Thus, the surfaces of the nichrome wires 53 and 54 slightly protrude from the surface of the rod-shaped support. Rod-shaped supports 55 and 56 on which nichrome wires 53 and 54 are arranged
are connected to air cylinders 59 and 60 by connecting rods 57 and 58, respectively. Figure 11 and 1
