Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention can quickly respond to changes in the length and shortness of the socks, the size of the inserted mount, and the number of pairs of socks when folding various types of socks while inserting the mount. The present invention relates to an apparatus that can perform appropriate automatic folding operations with high efficiency for any of the above.

<Prior art> As is known, when packaging women's socks, pantyhose, etc., these socks are folded in half or more using a backing paper as a core, and the folded items are made into bags using transparent plastic film or the like. The most common method is to insert the socks into packaging bags, and these operations are automated to save labor and improve efficiency, and they are also put into practical use as automatic sock folding machines and automatic sock wrapping machines. Known. For example, the one disclosed in Japanese Patent Application Laid-open No. 56-106721 is one of them, and the details are given in the publication, but as an automatic bagging device for socks, the conveyor 8 in the folding section 1, The mount 6 is pushed perpendicularly into the work 5 which has been fed into the workpiece 9 onto the mount 9, the work 5 is folded in half through the mount, and the workpiece 5 is lowered into the support bracket 11.
This is further folded in half by the pusher 12 from the side and sent to the conveyor 28 of the bagging section 3, and then the side guides 30, 30, opening attachment 32
and the opening 7a of the bag 7 via the pusher 33.
The work 5 folded into four is loaded into the bag 7 through the bag 7. In other words, when the workpiece 5 is long socks such as panty socks, it is necessary to fold it in half or in four to make it compact, and of course a backing sheet is required as a core for folding. As described above, the workpiece 5 is folded in half by pushing the mount 6 into it, and the mount 6 is built in. Furthermore, the workpiece 5 is folded in half using a pusher with one end of the mount as a boundary, folded in half to make it smaller, and then inserted into the desired bag. , and a series of necessary operations are automated, but conventional automatic sock folding and bagging devices, including this one example, have the following problems.

<Problems to be Solved by the Invention> In other words, in this type of automatic folding or packaging, both a small single mount and a large double mount that is twice the size of the single mount are used for the mount inserted into the sock as a core. However, in this case, the folding machine or device that uses a single-size mount and the folding machine or device that uses a double-size mount are designed separately from the beginning as specialized machines or devices for each size. Moreover, these machines and devices are all designed for folding one pair of socks, and cannot be applied to folding more than one pair of socks. It is difficult to change or adjust the folding details, and the machine is only a specialized machine that can be applied only to specific socks or to specific mounts, and is not versatile at all. Moreover, since sock manufacturers do not simply produce one type of socks, it is extremely inefficient to use dedicated machines for each size and purpose, as in the past, leading to an increase in overall packaging costs. It also becomes.

<Means for Solving the Problems> The present invention solves these conventional problems and is applicable to both single and double size insert mounts, and can be folded into one pair of socks and one or more pairs. In addition, various types of automatic folding can be achieved easily and automatically using the same folding device, so that different folding is possible depending on the length and shortness of the socks.

Mount 44 or 4 of sock 41 by the device of the present invention
The internal insertion and folding of 5 is carried out fully automatically as follows. In the present invention, there are cases in which a single-sized mount 44 is used and cases in which a double-sized mount 45 is used.
1, the toe section 4 is placed on the first conveyor 1, as shown in FIG. 3 in its operating state and in FIG.
A pair of socks 41 supplied with socks 2 at the beginning are transferred as the conveyor 1 rotates, and the toe portion 42
is conveyed downward while being held between the nip roller 31 and the rollers or wheels 1a, and is reversed with the toe portion 42 at the beginning from above the second conveyor 2 in front of the fourth conveyor 4 connected in series with the same conveyor 2. The paper is transported over the transport surface 4b in an extended state as shown in the figure. At this time, the first pusher 2
The first and third conveyors 3 are inactive. The first sensing member 1 thus placed above the second conveyor 2
1 detects the opening rubber part 43 of the sock 41, if the length of the sock 41 is long, the toe part 42 of the sock 41 passes over the discharge end of the front conveyance surface 4b and is carried into the fifth conveyor 5. Since it extends like a bridge over the end, by lowering the second pusher 22 simultaneously with the detection by the first sensing member 11, the toe portion 42 is moved between the front conveyance surface 4b and the fifth conveyor 5 as shown in the figure. By being pushed in between, the toe portion 42 is bent into a U shape, inserted between the lower nip roller 33 and the corresponding roller or wheel 4a, and placed on the rear conveyance surface 4c of the fourth conveyor 4. The bent toe portion 42 is sent out at the beginning, and the bent state is as shown in FIG. 4A. At this time, if the length of the sock 41 is short size, the toe portion 42 of the sock 41 is attached to the fifth conveyor 5.
The toe portion is not bent by the second pusher 22, and is delivered as it is from the delivery end of the front transport surface 4b to the nip roller 33 side. In the case of the toe-folded sock 41 transferred onto the rear conveyance surface 4c in this way, the sock 41 is transferred from the rear conveyance surface 4c onto the sixth conveyor 6 as shown in the figure. At this time, the sixth sensing member 16 detects the opening rubber part 43, and the approximately middle part of the length of the sock 41 reaches the rear conveyance surface 4.
c and the carry-in end of the sixth conveyor 6, and then drives the mount supply member 35 located above to send out the single-sized mount 44 orthogonally toward the socks 41. Therefore, the mount 44 is removed by vertically pressing down the sock portion located at the intermediate position between the output end of the rear conveyor surface 4c and the input end of the sixth conveyor 6.
The sock 41 is attached to both sides of the mount 44 in a U-shaped state with the core as the core, and the bent portion is held between the lower knit rollers 34 and 34d and sent out, so that the sock 41 is folded into the mount 44. 41 is transferred onto the conveyor 7 in the lower seventh conveyor 7, 7a as shown. In addition, when the mount 44 is vertically lowered and the socks 41 are folded, the sixth conveyor 6 is reversed so that the direction of conveyance is opposite to that of the rear conveyance surface 4c. The U-shaped bending of the sock 41 as it descends is smoothly performed. The U-shaped bending state of the sock 41 caused by pressing down the mount 44 is as shown in FIG. 4B. Insertion of the mount 44 and folding of the sock 41 are performed in exactly the same manner even in the case of a short-sized sock 41 in which the toe portion 42 is not bent.

In this way, the two-fold socks 41 with the mount 44 inserted are transferred onto the conveyor 7 of the seventh conveyor 7, 7a, and the tip thereof is sensed by the seventh sensing member 17 disposed on the conveyor 7 side. By advancing the third pusher 23, the pusher 23 presses the part of the sock 41 that is out of place from the upper end of the inserted mount 44, and the sock 41 is brought out of the folded state shown in FIG. 4B. , the nip roller 34d and the roller or wheel 8a that comes into elastic contact with the nip roller 34d while being bent into the four-fold state shown in FIG.
After that, it is sent onto the eighth conveyor 8 as shown in the third figure, and the single-sized mount 44
This completes the folding of the inserted pair of socks 41, and the socks 41 are transported from the eighth conveyor 8 to the ninth conveyor in the four-fold state with the mount 44 inside.
It passes through the conveyor 9 and then the conveyor 10 for carrying out, and is then transferred to the next process, for example, the process of charging into the intended packaging bag. At this time, the fourth pusher 24 and the nip belts 39, 40 located at an intermediate position between the eighth conveyor 8 and the ninth conveyor 9 are both inoperative.

Next, we will discuss the case of combining and folding two pairs of socks 41, 41 using a double-sized mount 45. Fig. 5 shows the operating state, and Fig. 6 A, B, C, and D show the folding state. The feeding of the socks 41 onto the first conveyor 1 is the same as in the case of FIGS. When the sock 41 is not present at the position of the member 14, the first pair of socks 41 supplied onto the first conveyor 1 remains in an extended state with its toe portion 42 at the front and the opening rubber portion 43 at the rear, From the discharge end of the conveyor 1 to the nip roller 31, the next second
The paper is sent onto the conveyor 2 and takes a posture of crossing over the front conveyance surface 4b of the fourth conveyor 4 connected in series beyond the discharge end of the conveyor 2. By sensing the opening rubber part 43 of this sock 41 by the second sensing member 12 on the second conveyor 2, the central part of the sock 41 is moved between the discharge end of the second conveyor 2 and the front conveyance surface 4b. After making sure that it is in the middle of the edge,
The pusher 21 is moved up and forward to fold the sock in half from the center of the sock 41 and feed it between the knit roller 32 located above and the corresponding roller or wheel 1a. The socks 41 are sent out from the nip roller 32 roller or wheel 1a in a half-folded state, transferred to the third conveyor 3 disposed above the front conveyance surface 4b in a half-folded state, and then transferred to the third conveyor 3 in a half-folded state. 3, the sock 41 is transferred onto the next fifth conveyor 5 as shown in FIG. 5, and when its tip reaches the position of the fourth sensing member 14, the fifth conveyor 5 is temporarily stopped. The socks 41 are put on standby. The first pusher 21 also descends to its original position. 2 which was then fed onto the first conveyor 1
The first sock 41 is transferred from the discharge end of the conveyor 1 onto the second conveyor 2 via the nip roller 31 roller or the wheel 2a, and then transferred to the first pusher 2.
1 is inactivated, the sock 41 is continuously transferred onto the front conveyance surface 4b of the fourth conveyor 4 in a stretched state, and the toe portion 42 of the sock 41 is placed above the discharge end of the front conveyance surface 4b. 3 sensing member 13, the second pusher 22 advances downward, and the nip roller 33, which is provided directly below the unloading end of the front conveying surface 4b, without bending the toe portion 42, moves forward. , and is fed between the corresponding rollers or wheels 4a, and is transferred in an expanded state onto the rear conveyance surface 4c by the rollers 33 or wheels 4a. Therefore, as shown in the figure, the second pair of socks 41 is transferred from the rear conveyance surface 4c through the forward rotation of the sixth conveyor 6 in a cross-over manner over the sixth conveyor 6. At this time, the postures of the first pair of socks 41 that led and the second pair of socks 41 that followed are as shown in FIG. 6A.

In this way, the opening rubber part 43 of the second pair of socks 41 is suspended on the rear conveyance surface 4c and the sixth conveyor 6.
The fifth sensing member 15 provided on the rear conveyance surface 4c
By sensing this, the double-sized mount 45 is delivered orthogonally to the sock portion located between the rear conveyance surface 4c of the sock 41 and the carry-in end of the sixth conveyor 6 via the mount supply member 35. At the same time, the first pair of half-folded socks 41 waiting on the fifth conveyor 5 is also transferred to the second pair of socks 41 located on the rear conveyance surface 4c by the rotation of the same conveyor 5.
It is transferred to the upper half of the Therefore, the mount 45
Due to the vertical descent of the second pair of socks 41, the same mount 45
It is bent into a substantially U-shape and guided into the entrance gap between the output end of the rear conveyor surface 4c and the input end of the sixth conveyor 6, with the rear conveyor surface 4c as the center. At this time, by reversing the sixth conveyor 6 and transporting it in the opposite direction with respect to the transporting direction of the rear conveyance surface 4c, the U-shaped folding of the socks 41 and accompanying folding are performed smoothly. 1 was hit and transferred to the top of the second half of the second pair of socks 41
The half-folded sock 41 of the second pair of socks is superimposed and carried together in the half-folded state, so that it is sandwiched between one side of the mount 45 and the second half of the second pair of socks 41. The mount 45 is inserted as shown in FIG. As a result of the rotation, it is pulled in between the lower seventh conveyors 7 and 7a in a pinched state through the forward rotation of both conveyors 7 and 7a under the bent insertion state shown in FIG. 6B. It turns out. This retracted mount 45 socks 4
The bent ends of Nos. 1 and 41 are detected by the eighth sensing member 18 provided on the conveyor 7 side of the seventh conveyors 7 and 7a, and the third pusher 23 advances, thereby causing As shown, while bending the toe portion 42 of the second pair of socks 41 that is further protruding from the upper end of the double-sized mount 45, the toe portion 42 of the second pair of socks 41 is bent and transferred to the nip roller 34d and the corresponding roller at the carry-in end of the eighth conveyor 8. The two pairs of socks 4 are pushed between the wheels 8a, and also on the seventh conveyor 7, 7a, by reversing the previous retraction and forwarding, the two pairs of socks 4 are
1, 41 and the mount 45 are in the folded position shown in FIG.
It will be transferred onto the conveyor 8. At this time, in the seventh conveyor 7, 7a, the conveyor 7a is the second half of the half-folded sock 41 and the second pair of socks 41, the mount 45 contained therein, and the front half of the second pair of socks 41 that overlaps the mount 45. This prevents the entire thick folded portion from loosening, making it effective for transportation in tight conditions.

Thus, the two pairs of combined socks 41, 4 are transferred onto the eighth conveyor 8 in the folded state shown in FIG.
1 and the backing paper 45 are transported like a bridge from the eighth conveyor 8 to the ninth conveyor 9 while being prevented from loosening by the nip belts 36 and 37, and the folded toe of the second pair of socks 41 at the top Part 42 as the 9th
When detected by the ninth sensing member 19 provided on the conveyor 9, the fourth pusher 24 moves downward, and the rollers supported by the carry-in end of the ninth conveyor 9 and the swinging lever 48 of the nip belt 39 At the intermediate position of the wheel 39a, the mount 45
By pushing in the position corresponding to the fold 45a,
Along with folding the mount 45 in half, the two pairs of socks 41, 41 are also folded in half at this position, and the nip belt 39, 41 is folded in half as shown in FIG.
It was pushed in between 40 and 40. At this time, the ninth conveyor 9 is reversed so that it runs in the opposite direction to the eighth conveyor 8, so that the folding in two is performed smoothly. In this way, the folded bodies of the two pairs of socks 41, 41 using the double size mount 45 held between both nip belts 39, 40 are sent from the delivery end of the nip belt 39 to the delivery conveyor 10 side, and are transferred to the next process. This is what happens. This fifth,
What is illustrated in FIG. 6 is a case where two pairs of socks 41, 41 are combined and folded using a double-sized mount 45.
On the other hand, when folding one pair of socks 41, this corresponds to the case where the first pair of socks 41 illustrated in FIGS. 5 and 6 is excluded, and the first pair of socks 41
It is sufficient to perform the folding operation using only the second pair of socks 41, excluding the socks 41, so the details thereof will be omitted. As described above, according to the apparatus of the present invention, the first conveyor 1, the second conveyor 2, the fourth conveyor 4, the sixth conveyor
The conveyor 6, the seventh conveyor 7, the eighth conveyor 8, and the ninth conveyor 9 are connected to a series of folding lines together with the first pusher 21, the second pusher 22, the third pusher 23, and the fourth pusher 24, as well as the mount supply member 35. By arranging the third conveyor 3 and the fifth conveyor 5 as bypass lines above the fourth conveyor 4,
Pair socks and two-pair socks are made using single-sized or double-sized mounts 44, 45 as cores,
This allows for automatic and efficient folding.

<Example> A suitable example structure of the folding device of the present invention will be described in the first example.
This will be explained in Figure 2. It is appropriate to use a belt conveyor for the first conveyor 1 to the ninth conveyor 9 used in the present invention, and furthermore, the delivery conveyor 10. It may be either a single belt with the full width of the belt, or a split belt with a plurality of strip belts arranged in parallel in the longitudinal direction, and a support plate may be freely disposed on the lower surface of the carrier surface. A motor or the like is used as a drive source for each of these conveyors and belts, and in the case of conveyors that can be forwarded in forward and reverse directions, a reversible motor or the like can be freely adopted. The first pusher 21 to the fourth pusher 24 are all movable back and forth in the target direction, and an air cylinder or the like is used as a driving source for moving them back and forth. Further, although only a pair of nip rollers are shown as the mount supply member 35 in the embodiment, this supply member 35 includes a single-size mount 44 to a double-size mount 45.
Although not shown in the figure, each mount 44 and 45 is stored in a separate stockyard, and is delivered to the member 35 side via an appropriate route. For the transfer, it is also possible to use a supply means such as that disclosed in the above-mentioned Japanese Patent Publication No. 106721/1988. Also the first
The embodiment shown in the figure is of course one example, and as long as there is no change in the arrangement order, the detailed design can be changed freely.The materials of the mounts 44 and 45 are flexible materials such as paper, It goes without saying that any material that can be creased can be freely selected.

<Effects of the Invention> The present invention is as described above, and as is already clear, even when a single size mount 44 is used for folding work with mounts for various socks,
Even when a double-sized mount 45 is used, this device can be used for both purposes without the need for a special device.Also, even if the size of the sock changes due to the size or length of the sock, it can be used depending on whether the toe portion is bent or not. In addition to being able to respond quickly, this device can not only fold one pair of socks, but also combine folding of two or more pairs, and the arrangement of the first to ninth sensing members 11 to 19 is Also, by changing or adjusting the position of these sensing members, it can immediately respond to the various size changes of various socks, and has a great feature in that it can always perform the appropriate folding operation accurately and easily. There is no need to separately install a dedicated device for each type or size, and it is extremely versatile in that it can fold various types of socks with a single device. Furthermore, by arranging the first pusher 21 to the fourth pusher 24, the folding form can be changed in various ways, and by rationally arranging the first conveyor 1 to the ninth conveyor 9, the device can be made large. It is possible to create a compact mechanism without the need for folding, and compared to conventional single-function automatic folding machines and devices, it has a versatile folding function that enables efficient folding of various types of socks. It has great utility value.
