Description

The present invention relates to a glove wrapping apparatus that efficiently folds a pair of gloves in which a pair of gloves are overlapped in the length direction into two.

  For example, a pillow packaging method as shown in FIGS. 8A and 8B is employed as a method for packaging the pair of gloves. (For example, refer to Patent Documents 1 and 2).

  In this method, a glove folded body b (a folded pair of gloves) is placed in order on a belt-like packaging sheet a that is rewound from a roll body, and both side edges ae of the packaging sheet a are pulled by a pulling roller c. While being superposed on each other, the overlapping portion is heat-sealed by the heat roller d. Then, by sequentially heat-sealing the cylindrical packaging sheet a surrounding the glove folding body b using a hot plate e before and after the glove folding body b, a package in which each glove folding body b is pillow-wrapped is obtained. It is formed.

  However, in this pillow wrapping method, it is necessary to previously fold the pair of gloves manually or using a dedicated folding device, resulting in an increase in the number of work steps. Moreover, when the volume of the glove folding body b is large, or when the folded state collapses, a part of the glove is bitten at the time of sealing, which may cause a sealing failure. In addition, since the size of the package becomes larger than that of normal bagging, it is disadvantageous for packing and transportation. In addition, it is necessary to change the size of the packaging sheet a according to the size of the glove folding body b. However, it takes time and effort to mount and adjust the packaging sheet a on the pillow packaging device, and in particular, small lots and many types. There is a problem in that productivity is impaired in glove packaging, which has a strong tendency to squeeze.

Therefore, the present invention uses a packaging bag that can be opened on one side, a series of folding a pair of gloves, packing a folded pair of gloves into a packaging bag (packing), and sealing the packed packaging bag. work to automate, without causing troubles such as biting a part of the glove during sealing, yet small lots, efficiently has excellent productivity in the case of many kinds, and gloves can be compactly packaged The object is to provide a packaging device .

The bottom plate 19C includes a plurality of guide shafts 20 that are vertically guided by guide cylinders provided on the base plate 19A on the lower surface thereof. One of the guide shafts 20 is a rack gear 20A having tooth grooves on the side surface, and meshes with a pinion gear 21 driven by a motor. A sensor (not shown) for detecting the height position of the uppermost packaging bag 4 is attached to the container main body 19, and the pinion gear 21 is driven when the height is lower than the set height position range, so that the bottom plate Increase 19C. Therefore, the bag accommodating means 17 can always maintain the uppermost packaging bag 4 within the range of the set height position.

  As shown in FIG. 4, the bag take-out means 18 includes a lateral moving tool 22 having a moving element 22A fixed to the frame base 12 and movable back and forth, and a front end of a support plate 23 attached to the moving element 22A. The revolving arm 24 is pivotally attached to the part and can revolve in a vertical plane, and the take-out suction pad 25 attached to the revolving arm 24 is provided.

  Note that a rodless cylinder is used as the lateral movement tool 22 in this example. The support plate 23 extends forward from a rear end portion fixed to the moving element 22A. At the front end portion, one end of the swivel arm 24 extends around a horizontal axis i extending in the transport direction. It is pivotally attached so that it can turn. The swivel arm 24 is formed in an L-shape comprising a first arm piece 24A extending downward from the one end and a second arm piece 24B bent horizontally from the lower end thereof and extending in the transport direction.

  The second arm piece 24B is provided with take-out suction pads 25 through a plurality of extendable cylinders 26 at a plurality of positions (two positions in this example) in the transport direction.

  Here, the bag take-out means 18 operates the cylinder 26 at the retracted position Jr of the moving element 22A. By the extension of the rod of the cylinder 26, the take-out suction pad 25 descends below the upper edge 19e of the container body 19 and sucks the uppermost packaging bag 4 among the packaging bags 4 to be accommodated. sell. At this time, a protruding portion W is formed and formed between the opening edge 4E and the extraction suction pad 25. Then, after the adsorbed packaging bag 4 is lifted by the reduction of the rod, the adsorbed packaging bag 4 can be taken out from the container body 19 by the forward movement of the moving element 22A to the advance position Jf. . Thereafter, the swivel arm 24 is turned 90 ° around the axis i to change the posture of the packaging bag 4 to a vertical state Y with the opening edge 4E facing upward.

  Next, the bag support means 5 includes suction means 29 having support suction pads 28 disposed on both sides of the packaging bag 4 in the vertical state Y held by the bag take-out means 18. As shown in FIG. 5, each supporting suction pad 28 is attached to the rod end of a cylinder 32 supported on the frame base 12 via a mounting bracket 31 so as to face each other.

Adsorbed from both sides by 28. That is, the sheet surface materials on both sides facing each other at the opening edge 4E are adsorbed from both sides. Then, after releasing the suction of the take-out suction pad 25, the bag take-out means 18 is returned to the initial state, whereby the packaging bag 4 can be received from the bag take-out means 18. Thereafter, the rod of the cylinder 32 is reduced, and the adsorbed sheet face materials are separated on both sides, whereby the packaging bag 4 can be supported in an open state.

In this state, as shown in FIGS. 6 (A) and 6 (B), the push-in plate 6 of the folding means 7 is lowered, and the pair of gloves 2 at the folding position P1 is moved downward through the spacing portion D. By pushing, the pair of gloves 2 can be folded in two and stored in the packaging bag 4 from the opening edge 4E. At this time, in order to prevent the pair of gloves 2 from being caught or scratched by the inner edge 11E of the conveyor unit 11, in this example, the guide rollers extending along the inner edge 11E of each conveyor unit 11 33 is arranged. In this example, the upper edge of the outer peripheral surface of the guide roller 33 is positioned on the conveying surface of the conveyor unit 11, and the inner edge of the outer peripheral surface is positioned on the inner side of the inner edge 11 </ b> E of the conveyor unit 11. .

  In addition, in order to securely store the folded pair of gloves 2 in the packaging bag 4, in this example, when the push-in plate 6 is pushed in, the lower part opens outward to guide the pair of gloves 2 into the packaging bag 4. A substantially V-shaped guide means 35 is attached to the bag support means 5. As shown in FIG. 6, the guide means 35 is made of a leaf spring material in the present example, and includes a pair of opening plates 34 and 34 attached to the interval portion D in a substantially V shape. The opening plate 34 is bent from, for example, a fixed piece 34a fixed to the mounting plate 12A of the frame base 12, and a blade piece 34b that is inclined so that the interval between the opening plates 34, 34 decreases downward. Have. When the pair of gloves 2 is pushed in, the opening plate 34 is pushed open in a direction in which a lower portion thereof is in contact with the inner surface of the sheet face material. Thereby, the pair of gloves 2 can be guided into the packaging bag 4 and can be prevented from being caught by the opening edge 4E. The opening plate 34 can be pushed open until it comes into contact with the support suction pad 28 via a sheet face material, and at this time, the sheet face material is narrowed between the opening plate 34 and the support suction pad 28. Thus, it is possible to prevent the packaging bag 4 from falling off the supporting suction pad 28 during storage. After the storage, the push-in plate 6 can return to a substantially V-shaped state (shown in FIGS. 5 and 7) with the lower part closed by the spring elasticity of the leaf spring material.

  The guide means 35 preferably prevents the glove pair 2 from being caught at both ends of the opening edge 4E of the packaging bag 4 when stored. Therefore, in this example, as shown in FIG. 7, a pair of width adjusting rollers 36 that adjusts the width of the pair of gloves 2 when they are pushed into the packaging bag 4 are provided across the space D before and after the conveying direction. Yes. The width adjusting roller 36 is preferably attached such that the distance between the width adjusting rollers 36 and 36 can be adjusted stepwise or continuously in accordance with the type of the pair of gloves 2.

  Next, the lifting / lowering holding means 8 holds the packaging bag 4 in which the pair of gloves 2 is stored in place of the bag support means 5 and moves the holding bag 4 to the lower sealing position P2. Specifically, as shown in FIG. 1, the lifting / lowering holding means 8 includes a movable base 41 that can be moved up and down, which is attached to a moving element of a lifting tool 40 such as a rodless cylinder, and is supported by the movable base 41 for the packaging. A pair of cylinders 42 arranged opposite to both sides of the bag 4 and a holding plate 43 attached to the opposite rod end of each cylinder 42 are provided. Then, by extending the cylinder 42, the packaging bag 4 in which the pair of gloves 2 is received is received from the bag support means 5 while being sandwiched between the holding plates 43, 43, and moved to the lower sealing position P2.

  Further, as shown in FIG. 8, the sealing means 9 includes a pair of cylinders 44 arranged on the frame base 12 through the mounting bracket 31 so as to face both sides of the packaging bag 4 and rod ends facing each cylinder 44. And a sealing terminal 45 to be attached. Then, the rod of the cylinder 44 is reduced, and the protruding portion W of the packaging bag 4 held by the elevating and holding means 8 is compressed between the seal terminals 45 and 45 and heated to thereby open the opening edge 4E. Seal. The sealing terminal 45 is a well-known welding terminal that seals the opening edge 4E by thermal welding, and an ultrasonic welding type in particular is excellent in responsiveness and can be suitably employed. When the lifting / lowering holding means 8 holds the packaging bag 4 at the sealing position P2, if the distance T between the sealing terminal 45 and the holding plate 43 is too wide, wrinkles are generated in the sealing portion, and the sealing performance and appearance are improved. Invite the fear of damage. From such a viewpoint, the interval T is preferably set to 2 mm or less.

  The sealed packaging bag 4 can be automatically dispensed to, for example, a carry-out conveyor 46 (shown in FIG. 1) provided below by releasing the holding by the lifting and holding means 8.

  As described above, the glove packaging apparatus 1 of the present invention can automate a series of operations that are a folding operation of the pair of gloves 2, a bagging operation of the folded pair of gloves 2, and a sealing operation of the packaged packaging bag 4. In particular, since the glove pair 2 straddled between the pair of conveyor sections 11 and 11 arranged in parallel is pushed downward by the push-in plate 6, the glove pair 2 is placed in the upper-opening packaging bag 4. It can be folded and folded into a bag for efficient bagging. At this time, since the folded glove pair 2 falls to the bottom of the packaging bag 4, troubles such as part of the gloves protruding and biting at the time of sealing can be prevented.

  Also, the position of the opening edge 4E of the packaging bag 4 accommodated by the bag accommodating means 17, the position of the opening edge 4E of the packaging bag 4 vertically supported by the bag support means 5, and the sealing means 9 The position of the opening edge 4E of the packaging bag 4 at the time of sealing is always constant regardless of the size of the packaging bag 4 in the depth direction. Therefore, even when changing lots, it is only necessary to adjust the position of the side plate piece 19Bb of the container body 19 in accordance with the size of the packaging bag 4, and no adjustment of other means is required. Excellent productivity can be exhibited even in glove packaging. Moreover, since it is packaged in a bag, it can be packaged more compactly than pillow packaging, which is advantageous for packing and transporting packages.
