Description

[Detailed description of the invention] As shown in FIG. 1, this invention consists of a top piece 92, left and right side pieces 93. 93', a bottom piece 94 that is an extension of one side piece 93, a glued piece 95 that is an extension of the other side piece 93', a front and rear extension of the top piece 92, a back piece 96. 96', and a side piece 93. The bent flaps 98. of the respective left and right extensions of 93'. 98', 99. A foldable sheet 91 with a foldable sheet 99' can be used to cover an irregularly shaped package a, such as a bun-shaped castella cake covered with a flexible interior.
This relates to an automatic packaging device that automatically packages products.

Conventional packaging in which a relatively hard package a shaped so as to fit exactly into the inner cavity when the sheet is folded is automatically wrapped using a foldable sheet 91 as described above. The device is equipped with flaps that approximately match the height of the covering object a on both sides of an elevating table whose left and right widths are slightly smaller than the bottom area of the covering object a. In the middle of the rise, the sheet 91 is pushed up by the top surface of the package so that the entire area of the top piece 92 covers the front and old lifting table, and the sheet 91 is raised upward together with the package. The side piece 93. 93' or fold down the bent flap 98. 98', 99. Turn 99',
Furthermore, the front piece 96. By lowering 96',
Then, the upper surface piece 92 is placed against the light pressure plate 29 to support the package and the sheet, and then the lifting table is lowered, and then the adhesive piece 95 and the lower surface piece 94 are bent onto the lower surface of the package. , and is fed out horizontally from the lower surface of the light pressure plate.

However, if the article to be wrapped is irregularly shaped and the article is to be slightly compressed and wrapped with the sheet 91, the irregular shape such as the curved shape of the article to be supplied to the lifting table may be avoided. Since the shaped upper surface protrudes above the upper edge of the flap, the upper piece 92 of the seat 91 is supported by the irregularly shaped upper surface in an unstable, non-horizontal state as shown in FIG.

However, the side piece 93. Accurate bending or bending of 93' or less is possible by accurately horizontally supporting the upper surface piece 92 by the upper surface of the envelope and the flap. It is no longer possible to compress the paper in the vertical direction and automatically package it using the sheet 91.

The present invention makes the height of the flap higher than the height of the envelope,
When the flap comes into contact with the lower surface of the light pressure plate, the flap is slightly lowered below the table against the spring elasticity so that the package can be compressed to a certain extent. One embodiment will be explained as follows.

FIG. 2 shows an example of a packaged object a suitable for packaging by the device of the present invention. For example, an irregularly shaped confectionery such as castella cake is hermetically sealed in a packaging bag b', and the sealed air C' that is not expelled is used to make the packaging bag. It is suitable for packaging items that are likely to rattle in the inner space created by the automatic folding of the sheet 91 unless compressed to a certain degree, such as the package a in which b' is swollen.

(In particular, as the enclosed air escapes over time, the volume of the envelope a decreases and the above-mentioned rattling becomes more severe.

) Figures 3 and 4 show the elevating table 1, which is a feature of the device of the present invention.
5 is an example, and consists of a rod 51 on the lower surface and a horizontal table 52 at the upper end of the rod 51, and the table 52 has an area slightly smaller than the upper surface piece 92 of the seat 91, especially on the left and right sides. In the direction, the folding plate 2 shown in FIG.
3. 23' has a shape that does not cause abutment even if it enters the lower surface of the enclosure a by a length that roughly matches the folding flaps 97, 97', and the rod 51 is loosely fitted onto the lower surface of the horizontal table 52. A downwardly movable flap support 53 is provided, a guide rod 54 depending from both sides of the rod 51 is passed through the support 53, and a push-up spring 55 is provided between the lower part of the guide rod 54 and the lower surface of the support 53. are provided, and shafts 56. on both sides of the support 53 are provided. 56 fix the flaps 16, 16 which protrude above both sides of the horizontal table 52.

The flaps 16, 16 are controlled by a device (not shown) to reverse the doll's tilting as shown by chain lines in FIG. 3 and to stand upright as shown in solid lines.

Then flap 16. 16 becomes the solid line posture in Figure 3,
When the flap support 53 is pushed up by the push-up spring 55 as shown in FIG. Adjust the height relationship of package a (see Figure 2).

FIG. 5 shows a conventionally known packaging device to which the present invention has been applied.

Therefore, the operation of the present invention will be explained based on FIG. 5 with reference to FIG. , 3 with the lower surface piece 94 on the rear side, and is fed by the sheet feeding piece 5 of the endless chain 4, and then fed to the position shown by the solid line by the pawl 7 of the positioning plate 6, which is waiting at the position shown by the chain line. It is stopped by the stopper 8.

On the other hand, below the stop position of the sheet 91, there is a supply table 9 for the packaged material a, and the side part of the supply table 9 is placed against the elevating table 15 which stops in a window hole 10 bored in the table. The package a stored in the transfer case 13 of the intermittent transfer conveyor 12 is sent out via the supply table 9 by the pusher 14, and is moved between the front and rear flaps 16 of the lifting table 15 by the guide 10' and stopper 11 on the supply table 9. (see FIG. 6I).

Next, the elevating table 15 opens the flap 1 as shown in FIG.
6 in an upright shape that is in close contact with both the front and rear sides of the covering object a, and ascends toward the shaped hole 18 shaped to match the area of the upper surface piece 92 of the upper sheet homer 17, and in the middle of its rise. Top piece 9 of seat 91 stopped as described above
Flap 16 on the underside of 2. 16 and raises the sheet 91 without contacting the covering object a (
(See Figure 6 II).

A bending guide plate 19 is provided on both left and right sides of the lower surface of the shaping hole 18 of the sheet homer 17 described above. 20, and a pair of bent pieces 21, 21' and 22, 22' are provided on both the front and rear sides of the guide plates 19, 20, as shown in Fig. 6, III.
Since the side piece 93 of the seat 91 is movable between the positions IV and IV, as the elevating table 15 rises,
．． 93' is bent down along each outer side of the flap 16 (see FIG. 6, III), and then the bent flaps 98, 99 are formed by advancing the bent pieces 21, 22 and 21', 22'. , 98', 99' are bent until the front and rear sides of the envelope a almost touch (see FIG. 6 IV).

Since the bent pieces 21, 22 and 21', 22' cannot be moved up and down, the elevating table 15 rises further above them and forms the forming hole 1 of the sheet homer 17.
8, the front and back pieces 96, 96' are separated upward from the bent pieces 21, 22, 21', 22', and bent flaps 98, 99 and 98', 99 are formed on the outside thereof.
' are overlapped to produce a downward bend that closely contacts the front and back sides of the envelope a, and at the same time the bent pieces 21, 22, 21',
22' is the withdrawal bar (see Figure 6 ■).

Thus, the upper surface of the horizontal table 52 of the lifting table 15 is exactly aligned with the side piece 93 of the seat 91 against the lower surface of the light pressure plate 29.
．． 93', front piece 96. It stops rising when it reaches an interval that matches the height, such as 96', but at that time the 4th
As shown in the figure, since the upper edge of the flap 16 comes into contact with the lower surface of the light pressure plate 2E, the flap support body 53 moves down a little against the elasticity of the push-up spring 55.

Thus, the upper surface piece 92 of the sheet 91 approaches the upper surface of the covering object a while remaining in contact with the lower surface of the light pressure plate 29, thereby slightly compressing the covering object a (sixth (See figure ■)
.

Further, at the same time as the lift table 15 stops rising, the folding plates 23, 23' from the front and back slightly advance to the lower surface of the envelope a, and the folding flaps 97. 97' and stop at that extended position for a while (see Figure 6 VI).

Therefore, the folding plate 23. 23' is compressed envelope a
and the sheet 91 are supported on the upper surface of the sheet homer 17 so that they cannot fall, and the elevating table 15 rapidly descends to the original position (see FIG. 6 Vll).

Folding plate 23. The only unbent portions of the sheet 91 supported by 23' are the bottom piece 94 and the glued piece 95, and the glued piece 95 is coated with adhesive glue 100 as shown in FIG. However, when the lift table 15 is lowered as described above, the glued piece folding plate 24 slightly advances from the front side of the upper surface of the sheet homer 17 to the lower surface of the package a, and the glued piece 95 is moved to the rear side. Fold-in (see Figure 6 VII).

Further, the lower piece folding plate 25 advances from the rear side of the upper surface to the lower surface of the glued piece 95 and folds the lower piece 94. At the same time, the glued piece folding plate 24 retreats, and in time with this, the folding plate 23. 23' also recedes, so the packaged item b, which has wrapped the packaged item a in the box-shaped sheet 91 whose parts have been folded and glued, is supported only by the lower folding plate 25, and its upper surface is pressed by the light pressure plate 29. , the packaged item b is transferred onto a rail plate 28 by a pushing plate 27 extending between endless chains 26, 26 on both sides (see FIG. 6 IX).

At this time, the elevating table 15 rises as shown in FIG. 6 III.

As exemplified above, the present invention is provided with a downwardly movable flap support 53 that is pressed against the lower surface of the horizontal table 52 of the lifting table 15 by the elastic force of the push-up spring 55, and the flap support 53 is attached to the horizontal table 52. Flaps 16.16 projecting upright higher than the height of the covering object a are attached on both sides, and the upper surface of the horizontal table 52 is the lower surface of the light pressure plate 29, and the side piece 93.16 of the seat 91 is attached. When the flap 16 is stopped at the upper limit position with an interval corresponding to the height of 93', the flap 16
, until the upper edge of 16 hits the lower surface of light pressure plate 29 and envelope a comes into contact with the lower surface of upper surface piece 92 of sea I 91,
It is configured to relatively lower together with the flap support 53 against the elasticity of the push-up spring 55, and the lowering movement of the lifting table 15 occurs following this relative lowering.

For this reason, the sheet 91 does not come into contact with the top surface of the packaged item a, unlike conventional packaging devices of the same type, and the flap 16. 16
Even if the upper edge of the covering object a is pushed up and has a curved surface, the sheet 91 is not supported by the curved surface as shown in FIG. 7, so it remains stable without swaying. do.

Therefore, this is particularly advantageous when outer wrapping is applied using the sheet 91 to an article a whose lower packaging bag contains air and has an unstable bulge.
