Description

[Detailed Description of the Invention] [Technical Field] The present invention involves temporarily attaching socks such as panty socks and seamless stockings on the endless track of a sock finishing machine, and placing the temporarily attached socks so that the foot shape is equally spaced. The present invention relates to a method and apparatus for increasing the number of socks in a sock finishing machine, in which the socks are spread over the entire body and inserted into the last of the foot little by little during the process of operation to completely attach the socks.

[Prior Art] Conventionally, as a method of attaching socks one by one to a foot last (template), Japanese Patent Application Laid-Open No. 57-77368 and Japanese Utility Model Application No. 1987-
No. 139800 is known.

In the former method, during sock finishing work, a worker opens each unset sock by expanding its welt part (perforation part) from the inside, and then pulls the leg part out from the welt part, and then removes the socks from the previous work. After the socks finished in the process are removed, they are sequentially inserted into the template group in an incomplete state as shown in Figure 9, that is, with gears formed at the legs of the socks, and in that state, the welt part is inserted. The sock legs are held by holding the gripping members at regular intervals in contact with the welt part of the sock inserted into the template without interfering with the progress of the template group, and by tucking them down below the template. After stretching the sock downward on the template to eliminate the gears on the leg of the sock (here, gears refers to the state where the sock sag on the last of the foot like a sag), it is pulled by the gripping member. The grip of the sock welt part is released.

The latter has a track surrounding the movement rail of the dyed finishing template, and is equipped with a mechanism on the track that controls the movement to pinch and separate the template, and the movement to move it up and down. A frame equipped with a clamper and a suction pipe located at an intermediate position between the clampers and having a movement mechanism that moves up and down is moved intermittently, and after lowering the suction pipe at a predetermined position, it is moved by a fixed distance to remove the socks. Only the welt part of the sock is inserted into the template.The toe of the sock is suctioned while holding a part of the welt part of the sock, and the welt part of the sock is grasped with a clamper and lowered along the template to place the sock on the template. It is designed to be inserted up to the tip of the toe.

However, in the former method, the worker opens the welt part of each unset sock from the inside, pulls out the leg part from the welt part, and places the leg part of the sock on a template. Because the sock is inserted with gears, the worker must pull the leg through the welt of the sock, and in order to increase productivity, the templates that pass in front of the worker must be inserted one after another. This has the disadvantage that many workers must be engaged in the work of inserting socks into the templates to keep up with production.

The latter method also has the advantage of requiring fewer workers, as the operator can open the welts of unset socks one by one from the inside and insert only the welts into the template. On the other hand, the frame, which supports the clamper that grips the welt of the sock and descends to insert the sock, and the suction pipe that can be raised and lowered, is moved intermittently, so the template does not insert the sock while it is running on the track. In order to insert all the way to the toe in one go, the clamper must move up and down quickly, and as a result, the sock is forced to be pulled and inserted, causing the leg of the sock to become abnormally stretched, especially when panty tucks occur. The tension of the yarn knitted with thin socks such as seamless stockings changes greatly, and the loops become disordered from the eyes of the socks, creating a striped pattern.The socks are set in this state, causing unevenness and reducing the product value. It had some disadvantages.

[Purpose] The present invention aims to suction the toe of the sock in the process of adding socks that have been temporarily attached to the last of the foot to the top of the last so that the sock can be easily inserted into the vertical position. It is an object of the present invention to provide a method and device for adding more socks to a sock finishing machine, which eliminates the various drawbacks mentioned above by using a means that allows the socks to be inserted little by little into the last of the foot and completely inserted to the toes. That is.

[Structure] The method and device for adding socks to a sock finishing machine according to the present invention includes a provisional sock mounting section on an endless track of a sock finishing machine, which is provided so that foot lasts can be spread at equal intervals and conveyed in one direction. It is installed at the next process position.

A sock toe suction device is placed above the trajectory of the next process position and at a position that does not impede the progress of the last, which sucks up the toe of the foot in progress above the top of the last and brings it into a nearly vertical position. are doing.

Further, at a position below the sock toe suction device and in parallel with the track, on both sides or on one side, the last of the advancing foot can be grasped and released together with the last attachment part of the sock, and can be moved up and down in diagonal directions. The supported sock chuck member is arranged to be lowered in synchronization with the progression of the last of the foot, released from grip on the sock, and then raised to return to its original position.

In addition, the sock toe suction device forms a suction duct into a long and narrow ventilation passage so that multiple foot-shaped sock toes traveling on the track can be vertically sucked at the same time, and the suction duct is guided to the suction port of the blower. It is set up like this.

Furthermore, the sock chuck member supports a chuck support frame so as to be movable up and down in a diagonal direction, and a plurality of rows of chucks are fixed to the surface of the chuck support frame on the side where the last of the foot advances, at equal intervals in the vertical direction, In each row, one or at least two chucks are arranged at a required interval so as to be able to grip and release the foot-shaped attachment portion of the sock.

With the above-described structure, the present invention sucks the toe of the sock into the suction duct while the temporarily attached foot last is moving, makes it vertical in the duct, makes it easier to insert the sock, and then moves the sock to the first row. The eye chuck grips the welt part of the temporarily attached sock, and the chuck is moved down a required distance in synchronization with the progression of the foot shape, and after releasing its grip, it moves back up to return to its original position. Then, with one chuck in the next row, grasp the welt part that was pulled down by the front chuck, and use another chuck to grasp the area where the welt part was first located, and simultaneously descend and lower the lowering device in the front row. The part that has been removed remains as it is, and the upper part is further inserted into the last of the foot. By repeating this, as the last of the foot progresses, the sock is gradually transferred to the chucks in the next row. Insert the sock (by the required size), and with the chuck in the last row, the welt part of the sock moves to the position below the foot shape, and the toe part of the sock is released from the suction force of the sock toe suction device, and the toe part is completely attached to the foot shape. It is designed to be inserted into the foot, and its feature is that while the foot last with the sock temporarily attached is spread on the trajectory at equal intervals, the toe of the sock on the last is moved upwards. Suction is applied to make it easier to insert the sock into a vertical position, and the sock is inserted into the foot shape little by little without forcing the leg of the sock, and the sock is completely attached to the foot shape using multiple sheets for each foot shape. The difference is that the foot impressions are performed sequentially with different degrees of insertion.

[Example] The positional relationship between the sock adding device and the sock finishing machine according to the present invention will be explained below based on the accompanying drawings.

On the endless track 4 of the sock finishing machine, there are, for example, as shown in Fig. 1, a setting section A for gathering socks and steam-setting them, a drying section B for drying the steam-set socks in the assembled condition, and a drying section B for drying the steam-set socks in the assembled condition. A cooling section C cools the socks, and a cooling section C cools the socks.
A sock extraction section D that pulls out the socks all at once, and a foot last 2 that pulls out the socks and transports them while being spread out at equal intervals.
The temporary sock attachment part E, into which only the sock welt part is inserted, and the toe part of the sock, which has been temporarily attached, are sucked up onto the last of the foot and placed vertically on the last of the foot. After grasping and lowering each sock one by one, the sock is released and automatically attached to the last of the foot up to the toe portion of the sock.

Further, on the endless track 4, at least five groups of carriages each supporting the last 2 are arranged so as to be able to run in one direction in a collective state or in a spread state, and the socks are placed at each working position. configured to be processed.

Next, the configuration of the sock adding device according to the present invention will be explained.

The sock adding device F stands vertically by sucking the toe of the sock upwards above the top of the last on the track 4 where the last of the foot 2 on which the sock 1 is temporarily attached is spread out at equal intervals and transported one by one. A sock toe suction device G is supported by a frame 12 on a fixed base 11, and preferably, as shown in the embodiment of the present invention, an air outlet 13 for blowing up socks that assists in suctioning the toe portion of the sock is connected to the above-mentioned orbit. 4 in parallel with the track.

Further, adjacent to the air outlet 13 and located below the sock toe suction device G, there are two units facing each other on both sides of the track 4 (however, depending on the type of socks, one side may be used).
A pair of sock chuck members are provided so that H can be lowered in the direction of movement of the last 2, and a crank exerciser J is provided.
The sock chuck member is configured to be able to reciprocate by the crank motion of the sock chuck member.

Next, details of each member and each device will be explained.

As shown in FIG. 2 and FIG.
A blower 14 is supported above the frame, and the blower's air outlet 18 is guided to one side of the track 4 through a duct 15 as shown in FIG. A blower outlet 13 is provided which can spray the remaining part of the worn socks 1.

Furthermore, as shown in FIG. 3, the suction port 16 of the blower is provided with a suction duct 17 having an elongated ventilation passage formed along the direction of movement of the last 2 so that the toe of the sock can be easily suctioned. As shown in FIG. 2, the length is such that a plurality of socks 1 on the lasts 2 spread at equal intervals can be sucked at the same time.

Here, the flow of air generated by the blower 14 passes through the air outlet 18 and from the air outlet 13 to the sock 1 above the last 2.
At the same time, the toe of the sock on the last 2 is sucked through the suction duct 17, and the toe of the sock is suctioned through the suction port 16 of the blower to make the toe of the sock stand vertically above the top of the last.The reason is as follows. If the toe part of the sock is not suctioned, the unattached part of the temporarily attached sock will fold and hang down in any direction on the side of the last, and when grasping with a chuck, the sock attached part and the unattached part will be held together. Since the sock has to be grasped and the sock cannot be inserted, suction is applied as described above to make it easier to insert the sock. In addition, by suctioning the device into a vertical position for additional installation, it is possible to perform additional installation work without difficulty.

As shown in FIGS. 4 and 5, the crank motion device J includes a chuck support frame 20 for a sock chuck member H.
is provided so as to be able to reciprocate along a guide shaft 21 which is fixed to the frame 12 and the fixed base 11 at an angle.

That is, as shown in FIG. 4, the chuck support frame 20 has protruding sliders 22 on the top and bottom of the chuck support frame.
A bearing or the like is fitted into the slider so that it can lightly slide on the guide shaft 21. Further, one end of a piston rod 23 is rotatably connected to the upper slider 22 by a rod pin 24, and the other end of the piston rod is connected to a crank arm 25 as shown in FIG. As shown in FIG. 4, the crank arm is rotatably supported by a bearing 19 and is fitted and fixed to the output shaft of the reducer 26, and the pulleys 27, 27 fixed to the input shaft of the reducer are connected to the motor. It is spanned by a pulley 29 fixed to the output shaft 28 and a belt 30.

In addition, as shown in FIG. 5, a pulley 31 is fixed to the output shaft of the reducer 26, and is spanned by a pulley 33 on the shaft of the detection drum 32 and a timing belt 34. Check K
A number of detectors 35 that send signals for gripping and releasing the sock are attached to the sock chuck member H in a number corresponding to each chuck K.
The timing is adjusted so that the detection drum 32 can rotate once during one reciprocation.

Here, when the motor 28 rotates, the belt 30,
30, reducer 26, 26, crank arm 25,
25, the chuck support frame 20 can be reciprocated diagonally by crank motion via the piston rods 23, 23, but the speed of this reciprocating movement and the horizontal movement distance are determined by the transport speed of the last 2 and the spread. When the foot last 2 reaches the position of the chuck K, the detector 35 sends a signal to the chuck K to grasp the sock 1, and the crank movement causes the chuck K to grasp the sock 1.
When the sock is lowered, the detector 35 sends a signal to the chuck K to release its grip on the sock, and the structure is such that the above operation can be repeated each time each last is transported.

The sock chuck member H is composed of a chuck support frame 20 supported so as to be able to reciprocate at an angle, and a plurality of chucks K in a plurality of rows attached in the vertical direction of the foot-shaped progressing surface of the chuck support frame. has been done.

In the embodiment of the present invention, the chucks K, K are arranged in five rows in the vertical direction as shown in FIG. 6, and as shown in FIG. In the fifth row, one chuck is installed on the top and bottom at a required interval, and each chuck K is provided so as to be adjustable in the vertical direction as required.

Furthermore, the number of rows and number of chucks K can be changed depending on the type and length of the sock, but in practical terms, the longer the length of the sock, the more the number of rows, and the shorter the length, the fewer the number of chucks.

The chuck K is for gripping and releasing the welt part, leg part or toe part of the sock temporarily attached on the last 2, and its structure is as shown in FIG. 7a. The pinion gears 43 and 43 are engaged with each other, and each pinion gear is fitted and fixed to a shaft 44 and a shaft 45, as shown in FIG. 7b, and the shafts 44 and 45 are rotatably supported by the block 41.

Furthermore, the large pinion gear 42 meshes with a rack gear 46, as shown in FIG.
It is directly connected to a piston rod 49 of an air cylinder 48 attached to the piston rod 49.

In addition, chuck plates 51 and 52 are fixed to the shafts 44 and 45 for gripping and releasing the sock 1 on the foot shape as shown in FIG. Rubber pads 53 are attached to the socks so as not to damage the surface of the socks and prevent them from slipping.

Here, when the air cylinder 48 is actuated to move the rack gear 46 in the direction of the solid line arrow shown in FIG. Grasp the sock 1 on the last 2 as shown in the figure. Also, if the air cylinder 48 operates in reverse, 5
1 and 52 open to release the grip of the sock 1 on the last 2.

The operation of the embodiment of the present invention will be explained using the above configuration.

Footprint 2 being conveyed on the endless track 4 of the sock finishing machine
The socks 1 before being set are temporarily attached to the socks, and the foot prints 2, which have been spread out one by one at equal intervals, are sequentially conveyed to the position of the additional sock attachment section and reach the air outlet 13 of the sock toe suction device G. At the same time, the unattached part of the sock 1, which has been temporarily attached, is blown up in the opposite direction of the air outlet, and the toe section 6 of the sock on the last 2 is sucked through the suction duct 17 of the sock toe suction device G, as shown in FIG. Stand vertically above the top of the foot as shown.

Subsequently, when the last 2 reaches the position of the chuck K in the first row of the sock chuck member H, the chuck grips the welt part 7 of the sock on the last according to the signal from the detector 35, as shown in FIG. 8a. At the same time, due to the crank movement, the chuck descends in accordance with the progression of the last 2 and in synchronization with the speed of the last, inserts the sock 1 into the last 2 to a required length, and detects the detector at the bottom dead center position of the crank movement. 35 provides a release signal for chuck K, which releases its grip on the sock welt 7 as shown in Figure 8b.

Subsequently, the sock chuck member H is raised by the crank movement, but no additional socks are added during this time. When the sock chuck member H reaches the top dead center,
As shown in FIG. 8c, the chucks K in the first row grasp the welt part 7 of the sock on the last 2 that is conveyed next, and the chucks K in the second row grip the upper position (initial welt part position) and the lower position (the welt part position lowered by the first row chuck K) that were first gripped by chuck K in the first row, respectively, and then turn the crank. As a result of the movement, it descends to the bottom dead center as described above, and the two socks 1, 1 are inserted into the last of the foot by the required length using the chucks K in the first row and the chucks K in the second row. (Fig. 8d) When reaching the bottom dead center, each chuck releases its grip on the sock due to the signal from the detector 35 as described above (Fig. 8d), and the sock chuck member H rises and reaches the top dead center position. The upper chuck and lower chuck of the 3rd row, and the chucks of the 1st and 2nd rows are the 8th chuck.
Grasp the socks on each foot shape as shown in the figure e,
By repeating the above-mentioned crank motion sequentially to the next row, socks with only the welt portion inserted over the last of the foot are moved from the first row to the fourth row as shown in FIGS. 8f to 8h. As the number of rows changes, the chucks are inserted little by little into the foot shape until the fifth row is reached, and the chucks in the first to fourth rows perform the above-mentioned action, but the upper chuck K in the fifth row is the toe part 6 of the sock
At the point when the sock chuck member is slightly lower than the top dead center position, the lower chuck of the fifth row grips the welt part 7 of the sock, and the sock chuck member When the sock 1 is completely inserted into the last 2 by the lowering of the sock 1, the chuck in the fifth row is released, and then the sock chuck member H is raised by the crank motion, completing one cycle (8th i. Fig. 8j). In addition,
It is also good to grasp and release the top and bottom of the fifth row at the same time like the first to fourth rows, but in this way, insert the toe part of the sock first using the upper chuck of the fifth row,
After loosening it slightly on the last of the foot (with a slight shift in timing), the lower chuck grips the welt part of the sock,
By lowering it, when you pull the sock that is slightly loosened at the tip, you will not have to forcefully pull this part because it is loose, and you can eliminate the slack.
Even with a uniform force (pulling force), the sock can be completely inserted into the last of the foot.

Such adjustment is performed depending on the timing of the detection drum 32 and the detector 35 shown in FIG.
The gripping and releasing can be performed simultaneously as in the fourth row, or the timing can be shifted as appropriate depending on the type of socks and the customer's preference.

In addition, in Figures 8a to 8j, the positions of the upper chucks in each row are slightly shifted vertically because the upper chucks are all placed at the same horizontal position as the chucks K that grip the sock welt in the first row. However, in this case, the chucks K adjacent to each other would come into contact with each other when releasing the grip, so the chucks K are slightly shifted vertically, and the lower chucks are moved downward by the stroke of the chucks in each row. The sock is provided so that it can be lowered by always grasping the welt part of the sock.

Due to this one cycle of the action of the chuck K, the sock 1 temporarily attached to the last 2 can be completely inserted up to the toe part 6, and the completely inserted last 2 runs on the track 4. If necessary, the operator performs alignment, etc., and then transports it to the setting section A.

[Effect] According to the present invention, on a trajectory where the foot shape with socks temporarily attached is spread out at equal intervals and transported in one direction,
The toe of the sock in progress is sucked up above the top of the last by the suction duct of the sock toe suction device, and the sock is placed in a nearly vertical position to make it easier to insert the sock into the last, and it moves up and down in synchronization with the progress of the last. With multiple rows of chucks in the sock chuck member, the first row of chucks allows the sock to be inserted a little (required size), and the multiple rows of chucks allow the sock to be completely inserted into the toe part of the foot. Because of this, the worker only has to insert only the welt part of the sock into the last part of the foot, and then the sock can be automatically inserted all the way to the toe.
This eliminates the labor-intensive work that conventionally required the worker to pull the leg from the welt of the sock and insert it into the last of the sock to the point where it causes gathers in the leg, and the last that passes in front of the worker can move quickly. Even when transported, the work can be carried out by a small number of workers.

Furthermore, in the first row, the chuck K grasps and lowers the welt part of the sock, which has been made vertical by suction, and inserts it into the required dimension template 2, and in the second row, the sock is inserted into the template in the first row. The upper and lower chucks of the second row grasp the upper part of the sock (where the welt part of the first row was located) and the welt part (the position lowered by the chuck of the first row), and the sock is moved to the first row. Since the sock 1 is inserted into the template 2 with the required dimensions in the same way as the eyes, and the sock 1 is completely inserted into the template 2 in this way, the force applied to each part of the sock when inserting the template is equalized. This eliminates the need to forcefully pull the sock, and conventionally, when inserting the sock all at once into the foot while running, pulling the sock forcibly causes the sock to set in a striped pattern due to irregularities in the welts and loops of the sock. This has the effect of preventing unevenness in socks, improving the rise of the product, and increasing the product value.
