Detailed Description of the Invention

[0001]

The present invention relates to a CD-S (CD8 cm
Board. Hereinafter, the present invention relates to an integrated packaging device for stacking a predetermined number of thin products such as "CD single") and packaging them.

[0002]

2. Description of the Related Art CD singles produced are put into a jacket one by one, and then packaged with vinyl, cellophane or the like to obtain a finished product. Then, the packed CD singles are stacked, for example, 50 sheets each, and the 50 sheets are set as a set, for example, in units of 4 sets (5
(0 × 4 = 200 sheets) is packed in a container such as a cardboard box and shipped. Generally, the collecting and packing work of the products is automatically performed by a collecting and packing machine.

[0003]

By the way, the above-mentioned C
Products such as D-single have slightly different thicknesses at the left and right ends of the product. For this reason, simply
In the case of stacking the sheets, the higher the height, the more the entire product inclines toward the thinner side, and the stacked products sometimes collapse and cannot be packed in a box.

The present invention has been made in order to solve the above problems, and even when products having different thicknesses at the left and right ends are stacked, they can be stacked straight and can be packed in a box without tilting. The purpose is to provide.

[0005]

SUMMARY OF THE INVENTION A stacking and packaging apparatus according to the present invention comprises a first stacking means for stacking a predetermined number of conveyed products in a vertical direction and sequentially discharging the products, and the first stacking means sequentially. Secondly, a product swiveling means for sending out every one of the discharged integrated products by turning the whole direction 180 degrees back and forth, and stacking and discharging the integrated products sequentially sent out from the product swiveling means in the upper and lower two stages. And a packaging means for packaging a predetermined number of the two-stage stacked integrated products sequentially discharged from the second collecting means into a predetermined container.

[0006]

The first stacking means stacks a predetermined number of individual products vertically and sends them out. The product turning means changes the entire direction of the products, which are stacked in a predetermined number, every other one forward or backward.
Turn 80 degrees and send out. Therefore, if two front and rear integrated products sequentially sent in the second stacking means are stacked in two upper and lower stages, the front and rear directions of the lower integrated product and the upper integrated product are exactly reversed and stacked. .
As a result, even if the left and right ends of the product have slightly different thicknesses, the reverse stacking cancels the difference in thickness between the left and right ends, and the stacked products may tilt and fall. Disappear.

The first stacking unit 9 repeats the above-described stacking operation of the products 2 three times. However, at the time of the third stacking operation, the shutter 15 _1, 15 first shutter 15 ₁ when the product 2 are stacked seven on _2, 15 ₂
Open and stack in the same manner on the product 2 that has been stacked up to that point. As a result, on the base 12, 9 + 9 +
7 = 25 sheets of product 2 are stacked in a state as shown in FIG.

When 25 sheets of products are stacked on the base 12 as described above, the cylinder 11 is operated, the base 12 is moved to the position of the left conveyor conveyor 18, and then the products are unloaded as shown in FIG. 25 products 2 stacked by the cylinder 19 are pushed out onto the conveyor 18.

The 25 stacked products 2 pushed out onto the conveyor 18 are carried to the position of the product swivel unit 20.
The product swivel unit 20 takes in the product 2 of 25 sheets piled up sent by the conveyor 18 to a predetermined position, and
As shown in (C), every other 25 sheets of the product 2 that are sequentially sent are rotated by 180 degrees and sent out. FIG. 3 shows a detailed structure of the product turning section 20.

In FIG. 3, reference numeral 21 is a product intake plate that is advanced and retracted by the cylinder 22, 23 is a lifting cylinder, 24 is a product swiveling cylinder attached to the lifting cylinder 23, and 25 is a tip of the product swiveling cylinder 24. A product-holding fork attached to the product, 26 is a cylinder 2
7 is a product stopper that is moved back and forth, 28 is a base 29
It is a product lift cylinder provided in.

When the product 2 of 25 sheets is sent to the position of the product swivel unit 20 by the conveyor 18, the cylinder 27 is operated and the product stopper 26 is advanced to the chain line position. Then, the cylinder 22 is operated, and the product intake plate 21 causes the cylinder 25 on the transport conveyor 18 to move.
The stacked products 2 are taken up to a position where they come into contact with the product stopper 26. This 25-pack product 2
Is held at the center position of the base 29 while being sandwiched between the product stopper 26 and the product intake plate 21 until the product turning cylinder 26 descends.

In this way, when the 25 stacked products 2 are held at the central position of the base 29, the lifting cylinder 23
Is operated, and the product turning cylinder 24 is lowered. Then, when the product gripping fork 25 at the tip of the cylinder surrounds the product 2 of 25 sheets and grips the product 2,
At the same time that the product stopper 26 and the product intake plate 21 are returned to their original positions, a product lift cylinder 28 having a rotating mechanism at the tip thereof is actuated and lifted to lift the product 2 to a position where it can be easily swung.

When the product turning cylinder 24 is operated in this state, the product 2 having 25 product holding forks 25 stacked therein.
The product 2 of 25 sheets is turned 180 degrees with the front and back turned 180 degrees while grasping. Product 2 is 180
When the product is turned, the product turning cylinder 24 ascends, and at the same time, the product lift cylinder 28 descends, and the product 2 is placed on the base 29.

The product swivel unit 20 is for the product 1 of 25 sheets stacked one after another from the first stacking unit 9
The above turning operation is performed every other space, and as shown in FIG. 8C, the direction of the product 2 of 25 sheets is changed every other space in the opposite direction. Then, the product 2 of 25 sheets whose direction is changed every other one is pushed out to the position of the second stacking unit 31 by the product discharge cylinder 30 of FIG.

The reason why the product 2 is held between the product stopper 26 and the product intake plate 21 until it is gripped by the product gripping fork 25 at the time of the turning operation is as follows. That is, C as the final product
The D-single is covered with vinyl or cellophane. Therefore, if the product stopper 26 and the product intake plate 21 are retracted before the product gripping fork 25 grips the product 2, the outer casing of the vinyl or cellophane, which has been pressed until then, springs back and 25 sheets are stacked. This is because there is a risk that the pile of the processed products may collapse.

The second stacking unit 31 is sequentially fed from the component revolving unit 20 and the direction thereof is reversed every other two.
As shown in FIG. 8 (D), the product 2 having a stack of 5 sheets is stacked in two steps, that is, the product 2 having a total of 50 sheets is stacked and discharged.

That is, the 25 sheets of product 2 sent to the second stacking unit 31 are pushed into the chute 33 by the product moving cylinder 32, and the product 2 which has been stored in the chute 32 immediately before is stored. The product 2 of 25 sheets is stacked in two layers as shown in FIG. 8 (D), and the product 2 of 25 sheets is stacked as two 50 layers to be carried out as a product of 50 sheets. At this time, the partition plates are sandwiched by the partition plate magazine unit 34 and the partition plate supply robot hand 35 between the products stacked adjacent to each other to prevent the adjacent products from colliding with each other and collapsing the load. .

As shown in FIG. 8C, the product 2 of 25 sheets sequentially sent from the product swivel unit 20 to the second stacking unit 31 is swiveled 180 degrees every other direction. There is. Therefore, in the second stacking unit 30, when the two products 25, which are forward and backward, which are sequentially sent, are stacked in two upper and lower tiers, as shown in FIG.
5 sheets are stacked in reverse. Therefore, even if the product has different thicknesses on the left and right ends, the difference in thickness is absorbed by the reverse stacking of 25 sheets each, and the height of the 50-sheet stacked product is the front and rear positions. In the same way, there is no longer a tendency for stacked products to tilt and collapse as in the past.

The products stacked 50 sheets in the above-mentioned manner are then packed in the stopper cylinder 3 at the next packing portion 36.
As shown in FIG. 8 (F), the empty cardboard boxes 4 sent from the cardboard carry-in conveyor 3 by the product inserting cylinders 38 and 39 are arranged in four rows as shown in FIG. 8 (E). Are packed one after another. FIG. 4 shows a detailed structure of the packing insertion mechanism portion of the packing portion 35.

In FIG. 4, the base 4 on which the product 2 is placed
0 is provided so as to be movable in the left-right direction by a slide guide 41. When the product is packed in the product box, the product insertion cylinder 87 pushes the base 40 onto the empty corrugated cardboard box 4 carried on the conveyor 3 and then pushes it out. , Base 40
The upper cylinder 39 is actuated, and the product insertion plate 42 at the tip thereof pushes the 50 stacked products 2 arranged in four rows on the base 40 into the empty cardboard box 4.

[0029] The four columns 50 sheets stacked products 2 arranged in pushing the empty cardboard box 4 is a flap (lid) free cardboard box 4 largely opened as 43 ₁ to 43 ₄ is illustrated The packaging section 36 of this embodiment achieves this by a flap processing mechanism as shown in FIGS. 5 to 7.

That is, FIGS. 5 and 6 show the left and right flaps 43 ₁ . 43 ₂ shows the detailed structure of the left and right flap processing mechanism for opening
By operating the flap cylinder 44 arranged at the upper part of the frame, the flap opening plate 47 is rotated via the rod 45 and the link 46, and thereby the left and right flaps 43 ₁ and 43 ₂ are pushed outward. It is the one.

FIG. 7 shows the detailed structure of the upper and lower flap processing mechanism portions for opening the upper and lower flaps 43 ₃ and 43 ₄ of the empty cardboard box 4. Two flap cylinders arranged at the upper and lower positions of the frame are shown. By operating 48 and moving the flap opening plate 49 attached to the tip thereof up and down, the upper and lower flaps 43 ₃ , 43
It is designed so that ₄ is pushed outward.

As described above, 5 in the packing portion 36
0 × 4 = 200 cardboard boxes 6 packed with product 2
1 is rolled over by 90 ° in the corrugated board box overturning section 50 in FIG. 1, the top and bottom of the corrugated board is correctly corrected, and then the corrugated board carrying conveyor 5 carries the card out of the apparatus.

[0033]

As described above, according to the present invention,
Since half of the products that can be stacked and stacked for box packaging are turned upside down so that they can be stacked, even when stacking many products with different thicknesses on the left and right ends,
Products can be stacked straight without tilting,
Unlike the conventional case, the product does not collapse in the middle of the box packing operation, and the box packing can be performed quickly and accurately.
