The present invention relates to an automatic packaging machine that automatically folds and wraps various packaging products, for example, ladies stockings, socks, underwear, etc., in particular, from the inspection process of various packaging products to be woven and transported, The process of inserting the product is automatically and continuously performed in one device, and the package is automatically turned upside down so that the folded portion of the wrapping paper (envelope) containing the product is directed toward the back side of the wrapping paper so that the label enclosing the wrapping paper can be attached to the back side. It relates to an automatic packaging machine.

In general, woven stockings, socks, underwear, etc. are inspected and folded with a thick inlay, inserted into a wrapping paper (vinyl bag), sealed with a label, and commercialized.

Therefore, well-woven tights, socks, underwear, etc., if the packaging state is poor, the value of the product will be reduced, so the packaging state should be more beautiful. Also, since the packaging products are produced in a continuous continuous weaving process, the packaging work can be done quickly and accurately. Mass production is possible only when

However, until now, the packaging work of the woven packaging product was folded by manual labor and then inserted into the wrapping paper and used as a primitive method.

Therefore, in order to commercialize a large quantity, that is, packaging requires a lot of manpower and performs several processes one by one, labor costs are excessively uneconomical, and work processes are made by hand, which causes work efficiency and productivity to decrease due to work time delay. It became.

Recently, a packaging machine that automatically wraps the product has been developed and used. However, the automatic packaging machine used is a separate inspection table for products (stockings, socks, and underwear) that are woven and transferred from the line. After the inspection, if the product is put on the automatic packing machine, the automatic packing machine operates to continuously fold the product with the inlay and insert it into the wrapping paper to commercialize the product. Since people have to move to an automatic packing machine, not only the inconvenience caused by the work, but also the packaging work can be done automatically and quickly, but the finished product is finished as shown in Figure 9 containing the product (a) The wrapping paper (plastic bag) (b) and the folding part (c) are folded to the front part of the inlay (d) where pictures and letters are drawn. Since the label (e) for sealing the folded portion (c) of the wrapping paper (b) is attached to this, there are many problems, such as poor packaging of the product to reduce the value of the product.

In order to compensate for the shortcomings of the recently developed automatic packaging machine, the present invention is equipped with an inspection table installed in one device connected to the line of the packaging machine, and the product which has been inspected is placed on the conveyor belt of the inspection table line.

Referring to the effect of the present invention configured as described above in detail.

As shown in FIG. 2B, the inspection plates 11 and 11 'of the inspection table 13 installed on one side of the automatic packing machine 1 are transferred to the product (a) woven and conveyed in a line by a conventional method. After the inspection by using it, it is placed on the conveyor belt 9 "in front of the inspection table 13, and the sensors (s) and (s') at the tip of the inspection table 13 detect the product (stocking) (a). The inner belt operation causes the conveyor belt 9 "to rotate to the left.

Accordingly, when the product (a) on the conveyor belt (9 ") is transferred and the product (a) is transferred to the end of the conveyor belt (9") at the tip of the inspection table (13), the lower product folding carriage (10 ') ) Moves to the left and at the same time the upper conveyor belt 9 'rotates itself.

Therefore, the product conveyed on the conveyor belt 9 "at the tip of the inspection table 13 moves on the lower conveyance belt 10 'and the conveyer belt 9' while the folding conveyer 10 'is advanced. When a) reaches the intermediate position of the lower adsorption folding stand 3 of the product while transferring on the rotating conveyor belt 9 of the opposite folding transfer table 10, the operation of the lower folding transfer table 10 is stopped. At this time, while the conveyor belt 9 'on the other side of the folding transfer table 10' is rotated in the same direction, the folding transfer table 10 'is returned to its original shape as shown in FIG. (3) The compressor (not shown) inside the bed (2) sucks the air through the air hose 24 connected to the lower end and adsorbs the product (a). Will come back.

In this way, the both ends of the product (a) adsorbed to the adsorption folding stand (3) remain in the state obtained by the left and right folding transport tables (10) and (10 ') for a predetermined length while the air continues to adsorb. do.

At this time, a plurality of adsorption valves 18 installed on the inlay (d) storage box (6) on the left side of the adsorption folding stand (3) adsorb the inlay (d) to ride the inlay adsorption transfer unit 19 to FIG. As shown in the drawing, the advancing and transporting portion 19 moves to the right and the inlay d is placed on the folding portion 8 and the rail 20. The lower portion of the rail 20 shown in FIG. As the chain 4 "rotates to the right, the inlay feeding interval 21 pushes the inlay d to transfer it to the bottom of the inlay folding portion 8.

At this time, when the inlay folding portion 8 is lowered and the inlay d is bent, the suction valve 22 connected to the air cylinder 23 is bent, and at the same time, the right portion of the inlay d which is not folded is adsorbed. The air cylinder 23 is lowered to raise one side of the inlay d on the upper surface of the product (a) that is mounted on the adsorption folding stand (3).

Thereafter, as shown in FIG. 2E, the suction valve 22 is returned to its original position, and the left folding carriage 10 of the bed 2 is operated to move to the right to obtain the conveyor belt 9. After pushing one side of the tongue (a) to be folded on the upper surface of the inlay (d), and when it returns to its original position immediately another folding carriage (10 ') of the right side of the head (2) as shown in Figure 2f The operation is transported to fold one side end of the product (a) on the conveyor belt (9 ') to overlap again.

The engagement groove 60 of the Geneva mechanism 33 and the projection 67 of the swing lever 66 are released, and the projection 57 of the rotary lever 56 is inserted into the insertion groove 50 of the Geneva mechanism 33. When engaged and rotated, the Geneva mechanism 33 rotates the gear 32 by a predetermined amount so that the adsorption folding stand 3 of the intermittent transfer part 5 intermittently moves, and the rotation lever 56 further rotates to make the swing lever ( When the 66 is separated from the cam protrusion 64 and descends, the protrusion 67 of the swing lever 66 is in contact with the circumferential surface of the Geneva mechanism 33 and is coupled to the next locking groove 61, and at this time, the rotary lever ( The protrusion 57 of the 56 leaves the insertion groove 50 of the Geneva mechanism 33. When the rotary lever 56 further rotates, the cam protrusion 65 of the rotary lever 56 lifts the swing lever 66. Raised Geneva Organization (33) The engaging groove 61 of the locking lever 66 and the projection 67 of the swing lever 66 are released, and the projection 58 of the rotary lever 56 engages with the next insertion groove 51 of the Geneva mechanism 33 to rotate. Subsequently, the above-described operation is repeated, so that the adsorption folding stand 3 of the intermittent transfer part 5 continues to be intermittently transferred so that the chain 4 of the intermittent transfer part 5 on the upper side of the bed 2 is bed ( 2) The Geneva gear 34 is operated by the operation of the Geneva mechanism 33 connected therein to rotate the gear 32 of the chain 4 to rotate the chain 4 by a certain distance, that is, the Geneva mechanism 33. The suction folding stand 3, which is installed on the chain 4 and is obtained on the chain 4 by being shifted by one motion pitch, is released from the upper folding carriages 10, 10 'and at the same time new ( Next) the adsorption folding stand (3) is to be placed under the upper folding transfer table (10), (10 ').

At this time, the cam link 27 provided on one side is cam-operated by the lower guide piece 29, while the adsorption folding stand 3 which the folded product a is obtained transfers, and the inlay of one side of the adsorption folding stand 3 is cam-operated. The bending piece 26 presses and folds the center portion of the inlay d, which is spread while the cam 28 is rotated by the engagement operation of the gear 28 to cover the product a.

While the above operation is made, the upper surface of the other adsorption folding stand 3, which has been transferred to the folding transfer table 10 and the lower portion of the 10 ', is subjected to the same operation as the above-described operation, thereby again deceiving the product (a) (d). It is folded and becomes high state.

As the operation is continuously performed, the chain 4 is operated by the Geneva mechanism 33 by one pitch distance so that the suction folding table 3 folded up on the product (a) of the tip is placed on the bottom of another guide piece ( 29 '), the upper side of the upper suction plate (3) of the adsorption folding stand (3) connected to the idle gear 30 by the cam link (27') opposite the suction folding stand (3) is cam-driven by the guide piece 29 ' 3a) is reversed with the product (a) by 180 ° and transferred one more pitch to position at the end of the chain (4) of the intermittent transfer part (5) and stops the Geneva mechanism (33) and cam inside the bed (3). A plurality of suction holes 25 'are formed and operated by connecting to the 36 and the lever 37, and the insertion aid carriage 35 connected to the air hose 34' is provided with the cam 36 and the lever 37. It is still folded while being transported and positioned under the product (a) at the bottom of the upper adsorption plate (3a) of the adsorption folding stand (3), which is advanced and inverted by the operation. After the folding section 38 has folded the last inlay (d) of the last portion, the insertion aid transfer table 35 returns to its original position while absorbing the product (a) completely folded by the known compressor operation.

At this time, the adsorption valve 18 ′ at the upper part of the packing box storage box 14 installed at the rear of the bed 2 of the automatic packing machine 1 operates to absorb one side of the packing paper b in the packing box storage box 14. At the same time, the wrapping paper with one side lifted by the suction valve 18 'as shown in FIG. 5 by the operation of both side expansion spaces 45, 45' links 46, and 46 'in front of it. It is inserted into (b) to completely open the wrapping paper (b).

At this time, the wrapping paper pusher 42 connected to the motor M 'ascends the inclined guide rails 43 and 43' as the wrapping paper b exits, thereby adsorbing the next wrapping paper b to the adsorption fixing piece 47. This adsorbed state is made continuously.

While the above operation is performed, the feed insertion stand 39 on the upper side of the insertion aid feed table 35, which absorbs the fully folded product (a), is moved forward by the operation of the air cylinder 23 '. While pushing the product (a) adsorbed on the upper surface of the stand (35) toward the guide rail (20), the product (a) is pushed into the inside of the wrapping paper (b) opened by the expansion spaces 45 and 45 '. Let's go.

After the product (a) is completely inserted into the wrapping paper (b) as described above, when the feed inserting table 39 returns to its original position, all the driving operations are completed, and the folded product (a) is the wrapping paper (plastic bag). It will be fully inserted inside.

Thereafter, the packaging (b) containing the product (a) is removed, and the label (e) is attached by a known labeling device (not shown), and the opposite side with the text and drawings as shown in FIG. As a result, the wrapping paper is folded into a finished product having the label (e) attached thereto.

Therefore, after inspecting products on a separate inspection table as in the prior art, if the inspection table and the automatic packaging machine are configured in one device instead of one by one, they are connected to the conveyor belt and only the products that have undergone the inspection process are put on the conveyor belt. If the machine is automatically transported, it can be packed in an automatic packaging machine, so the work process is very easy and simple, and all the transfer processes are composed of automatic lines, which improves the work efficiency per unit time and enables mass production. In addition, the product can be reduced, and the product can be reversed once the product is folded in the automatic packaging process so that the existing front label attaching part is placed at the back side. Product value and dignity due to beautiful packaging One will obtain an effect that can be classy.
