Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for attaching socks, such as seamless stockings and panty socks, to a template of a sock finishing machine. The pre-applied sock, with the toe side hanging down from the top of the template, is automatically folded down and the toe of the sock is brought into contact with the top of the template, making the sock taut and wrinkle-free. This invention relates to a sock tucking-down device for a sock finishing machine that can be installed in a sock state.

BACKGROUND ART As shown in FIG. 8, a sock finishing machine has a large number of telescopic pantograph-structured carriages 101 connected in an endless manner so that the carriages 101 move on a horizontal elliptical trajectory. 1
01 is vertically provided with a template 102 on which a sock is attached from the opening side. Along the elliptical orbit, there is also a mounting section 110 for mounting socks on the template 102, a setting section 120 for steam-setting the worn socks, a drying section 130 for drying the steam-set socks, and a drying section 130 for drying the socks after drying. A removing section 140 is sequentially provided, and the mounting section 110 is provided with a tuck-down device 200 that functions to automatically pull down the socks to be disposed of.

Such a device is known from Japanese Patent Application Laid-open No. 158374/1983. This device uses a thin template 103 formed into a U-shape, which is the shape of a person's lower body when viewed upside down from the front and rear directions, as shown in FIG. Therefore,
In the case of a tuck-down device equipped with such a template 103, since the template 103 does not include a heel portion, it cannot be applied to recent sets of heeled socks. In other words, if the sock is worn with the toe section located at the upper end of the template 103, the heel section cannot be set by steam heating. For this reason, in order to apply it to socks with heels, JP-A-57
- A tuck-down device such as No. 77368 has been proposed.

As shown in FIG. 10, this device has a plate 104 that resembles the shape of a human lower body when viewed upside down from the side.
In addition, a gripping member having a means for successively contacting and separating both sides of the waist part of the sock attached to the templates arranged at an appropriate distance apart is provided, and this gripping member is attached to the templates that are conveyed at a constant interval. The configuration includes a drive mechanism that raises and lowers the template in synchronization with the conveyance of the template, and moves the template in the direction of movement of the template. Therefore, with this device, it is possible to set heeled socks by positioning the heel portion at the upper end of the template.

Problems to be Solved by the Invention However, in the case of the device disclosed in JP-A No. 57-77368, the gripping member presses both sides of the waist of the unset sock placed on the template from the outside and descends. Since the force exerted on the socks mainly acts downward, the gripping member slips against the socks, making it impossible to tuck down the socks reliably and requiring correction work.This also causes the problem that the socks become defective after being set. It was hot. In particular, socks using highly elastic yarns such as polyurethane fibers are susceptible to the above-mentioned problems because of the strong forces involved in the template.

The present invention has been made to solve such problems, and an object of the present invention is to provide a sock tucking-down device for a sock finishing machine that can reliably tuck down a sock that is partially covered by a pattern thread. .

Means for Solving the Problems A sock tucking-down device in a sock finishing machine according to the present invention is provided with a sock finishing machine equipped with a template for applying and wearing socks that is conveyed on an elliptical track. A holding member is provided facing the conveyance area of the template for holding both sides of the waist part of the sock attached to the socks in a pinched state and lowering the socks, and the holding member comes into contact with and separates from the template. It consists of a pair of first members that can be opened and closed, and a pair of second members that are disposed below the first members and that open and close between them. The present invention is characterized in that it is provided with a drive mechanism that moves the holding member up and down in synchronization with the conveyance of the template and moves it in the direction of movement of the template to attach the sock.

Effects In the present invention, since the holding member holds the waist of the sock attached to the template in a pinched state,
The socks are surely pulled down.

EXAMPLES The present invention will be specifically described below with reference to the drawings.
FIG. 1 is a front view of a sock tucking-down device according to the present invention installed in a mounting section of a sock finishing machine, as seen from the outside direction of the elliptical orbit in the mounting section, and FIG. FIG. 3 is an enlarged plan view of the vicinity of the holding part 20 (also showing the elliptical orbit), and FIG. 4 is a perspective view showing the main parts of the device of the present invention. .

Reference numeral 2 in the diagram of FIG. 3 is a template installed vertically on the carriage 1 having a telescopic pantograph structure that moves on an elliptical trajectory. It is conveyed in an oblique state. As shown in Fig. 5 (perspective view), the template 2 consists of a pair of plates 2a shaped like a person's lower body seen upside down from the side, which are placed opposite each other at a length apart. A protruding piece 2b is provided at a distance from each of the protruding pieces 2b for folding the butt part of the sock into a concave shape. A sock tucking-down device 10 is provided inside the elliptical track facing the conveyance area of the template 2.

The sock tucking-down device 10 is equipped with a plate-shaped rail 3 whose upper side is inclined toward the extraction section side (the left side in the example of FIG. 1; hereinafter, this direction and the opposite direction will be referred to as the left-right direction). A vertically movable table 30 connected to this rail 3 is provided so as to be movable along the longitudinal direction of the rail 3 in order to integrally move a holding section 20 for holding and tucking up socks. .

A longitudinally movable table 40 is interposed between the vertically movable table 30 and the holding part 20, and moves the holding part 20 forward toward the track side or backward in the opposite direction. The unit 20 can be moved forward toward the track side or retreated in the opposite direction relative to the vertically movable table 30 while being held in a state in which movement in the vertical and horizontal directions relative to the vertically movable table 30 is restricted. ing.

The vertically movable table 30 sandwiches the rail 3 from both green sides, and supports both greens at two points above and below, respectively.
Rollers 31, 31, 31, 31 are attached and are provided so as to be movable in the vertical direction along the rail 3. Sprockets 4 and 5 are pivotally attached to the upper and lower ends of the front side surface of the rail 3, respectively, and an endless chain 6 is suspended between both sprockets 4 and 5. A sprocket 7 is also attached to the other end of the shaft 5a that supports the lower sprocket 5, and the sprocket 7 is connected to the drive shaft of a drive motor (not shown) by a chain 8 suspended between the sprocket 7 and the drive shaft of a drive motor (not shown). Rotational force is transmitted. This rotational force is transmitted to the sprocket 7 via the chain 8 and drives the chain 6 and the upper and lower sprockets 4 and 5.

A part of the chain 6 and the vertically movable table 30 are connected by a chain connecting member 34, and the vertically movable table 30 reciprocates up and down along the longitudinal direction of the rail 3 as the chain 6 rotates. The angle of inclination of the rail 3 with respect to the vertical direction is determined by the relationship between the distance between the templates and the length of the sock to be tucked down. That is, it is determined so that the horizontal length of the moving range of the vertically movable table 30 is equal to or less than the distance between the templates, and the vertical length thereof is equal to or greater than the length for tucking up the socks. Further, the operation of the vertically moving table 30 is linked to the conveyance of the template 2 in the advancing direction of the template 2, that is, in the horizontal direction,
And they are synchronized so that they move at the same speed.

Spring 11 is provided at the upper end of the rail holding member 9 that holds the rail 3 and at the vertically movable table 30, respectively.
The upper and lower ends are hooked, and the spring 11 relieves the shock when the vertically movable table 30 turns back at the upper limit of its vertical motion range. The shock absorber 12 is adapted to relieve the shock when the vertically movable table 30 turns back at the lower limit.

On the side surface of the vertically movable table 30 on the template side, front and rear movable table support shafts 32, 32 are provided at upper and lower positions along the rail 3, respectively.
are fixedly installed in parallel, and two sets of holes 41, 42 formed on the upper and lower sides of the front and rear movable base 40 are fitted into the two front and rear movable base support shafts 32, 32, respectively. , 32 is fixed with a fixing plate 33 parallel to the side surface. Therefore, the longitudinally movable table 40 can move forward toward the track side or retreat in the opposite direction with respect to the vertically movable table 30 while its movement in the vertical and horizontal directions is restricted.

A plate-shaped front and rear guide 42 of approximately the same length is attached to the rail holding member 9 in parallel with the rail 3, and the front and rear guide 42 is shown in FIG. 6 (side view).
As shown in , it is bent in the middle so that the lower end side is set back with respect to the carriage 1 than the upper end side in plan view. The shafts of two guide rolls 43, 43 sandwiching the guide 42 are fixedly installed on the front and rear movable base 40, and the guide rolls 43, 43 are shaped like the guide 42.
43 follows and moves the front and rear movable base 40 forward or backward. Note that the length of the support shaft 32 is determined by the length of the back and forth movable base 40 that follows the shape of the guide 42.
The dimensions are set so that there is no problem in moving forward or backward.

Further, the upper end of a vertically long mounting shaft 44 is fixed to the front and rear movable table 40.
An arm holding stand 22 for supporting two sets of arms 21a, 21b, 21a, 21b sandwiching the template 2 is attached to the lower end of the arm holder 4. This arm holder 22 moves forward and backward by the movement of the front and rear movable base 40, but this movement is designed to prevent it from coming into contact with the elliptical trajectory when the arm holder 22 descends straight without moving forward or backward. The amount of advance and retreat is determined so that the arm holding base 22 does not come into contact with the elliptical orbit.

The base end side of each pair of arms 21a, 21b is an arm holding stand 2.
2, and its shafts 23a, 23
A large gear 24a and a small gear 24b are fixedly installed at the lower end of the gear b, respectively, and the large gear 24a and the small gear 24b mesh with each other. The two shafts 23a, 23a to which the large gears 24a, 24a are attached are attached to the arm holding base 22.
Two arm rotation cylinders 25 provided on the sides of the
25 for rotational driving. That is, the arm rotating rod 2 is attached to the shafts 23a, 23a.
Fix one end side of 6, 26, and arm rotation rod 26, 26
Long guide holes 26a, 2 in the longitudinal direction are provided on the other end side.
6a, and guide pins 25a, 25a provided at the ends of the cylinder rods of the arm rotation cylinders 25, 25 are inserted into the guide holes 26a, 26a.
Therefore, when the cylinder rod of the cylinder 25 advances or retreats, the pair of arms 21a and 21b rotates to advance toward the template 2 and pinch it, or rotate to open to a position that does not hinder the transportation of the template 2. You will have to retreat. For this operation, the arm rotation cylinders 25, 25 are operated synchronously, and the dimensions of the cylinder rods, arms 21a, 21b, etc. are the same for each group, so that the two sets of arms are moved at the same timing and at the same position in each group. It is determined to work in relation to each other.

At the tips of the arms 21a and 21b, a holding member 27 is provided that performs a vertical pinching operation on the inside of the arm, and this holding member 27 is attached to the arms 21a and 21b.
Upper holding member (first member) 27a fixed to b
and a shaft 27c provided on the outside of the arm of the upper holding member 27a.
(See FIG. 2). The lower holding member 27b is rotatably driven around a shaft 27c by an air cylinder 28 provided on each arm 21a, 21b, and this drive causes the upper holding member 27a and the lower holding member 27b to perform the above-mentioned picking operation. do.

This pinching action and the opposite opening action and the above-mentioned arm 21
The opening operation, which is the opposite of the operation in which a and 21b sandwich the template 2, refers to the upper and lower movement based on the number of pulses counted by a pulse generator (not shown) having a high-speed counter function installed in the lower sprocket 5, which drives the chain 8, respectively. It is linked with the movement of the moving table 30. That is, the pulse generator is reset when the vertically movable table 30 reaches, for example, the upper limit of its vertical motion range, and the height position where the vertically movable table 30 descends and the holding member 27 picks up the sock 100 is reached. When the first pulse number corresponding to a slightly higher position is reached, the arm rotation cylinder 25 advances the rod, and the above-mentioned pinching operation shown in practice in FIG. 7 is performed. Next, the vertical moving table 30 moves the socks 100
When the second number of pulses corresponds to the height position at which the rod is to be pinched, the air cylinder 28 advances the rod to the seventh position.
The above-mentioned picking operation shown by the broken line in the figure is performed. After that, the vertical moving table 3 when the socks 100 have been picked
Corresponds to the 0 height position. When the third pulse number is slightly larger than the second pulse number, the holding member 27 is slightly separated from the template 2 as shown by the dashed line in FIG. To achieve the same condition, the cylinder 25 retracts the rod a little. After that, when the vertically movable table 30 descends and the holding member 27 reaches the height position at which it finishes folding down, the number of pulses becomes the fourth number of pulses corresponding to that height position, and the cylinder 25 and the air cylinder 28 are retracted together to perform the opening operation described above and the opening operation shown by broken lines in FIG. 1st above
The fourth to fourth pulse numbers are appropriately determined depending on the sock dimensions, operating conditions, and the like. In particular, the fourth number of pulses may be set not only to one, but also to two or three, and may be switched and used depending on the sock size, etc.

Note that the shapes of the arms 21a and 21b and the holding member 2
The dimensions of 7 are such that even if the width direction of the template 2 is inclined with respect to the direction of movement of the elliptical orbit in the attachment part due to the expansion and contraction of the pantograph structure of the carriage 1, the holding member 27 can be attached to the front and back surfaces of the template 2 simultaneously or It is determined that they come into contact or separate at approximately the same time. Further, for this contact and separation, the arm holding base 22 may be provided with a function of rotating around the mounting shaft 44.

An outlet 29a of the air pipe 29 is provided below the lower limit of the movable range of the lower holding member 27b, and the outlet 29a faces diagonally upward, so that air is supplied to the air pipe 29. .

Therefore, according to the present invention, as shown in FIG. 7, air is blown from the outlet 29a of the air pipe 29 toward the waist 100a of the sock 100 attached to the upper part of the template 2, thereby blowing the waist 100a. By creating a pleated shape and then operating the air cylinder 28, the upper holding member 27a and the lower holding member 27b hold the folded portion in a pinched state. Also,
The holding member 27 descends in synchronization with the conveyance of the template 2,
Also, since it moves in the direction of movement of the template 2, it moves along the front and back surfaces of the template 2.

Note that in the above embodiment, the upper holding member 27a is fixed to the arm and the lower holding member 27b is movable, but the present invention is not limited to this, and the lower holding member is fixed to the arm. However, the upper holding member may be movable to hold the sock in a pinched state. Alternatively, it goes without saying that the upper holding member and the lower holding member may move together to hold the sock in a pinched state.

Further, in the above embodiment, a holding member consisting of two pieces,
That is, the upper holding member and the lower holding member are used to hold the sock vertically, but the present invention is not limited to this, and the present invention is not limited to this. It may also be configured using a piece of material.

Furthermore, in the above embodiment, the air pipe 29
Although the present invention is not limited to this, the present invention is not limited to this, and the present invention is not limited to this, and the present invention is not limited to this. Of course, it can also be implemented by configuring the device to pick up socks.

Further, in the above embodiment, the socks to be tucked down extend up to the waist, but the present invention is of course not limited to this, and can be similarly implemented with socks that extend up to the legs.

Furthermore, the present invention is applicable not only to socks with heels but also socks without heels.

Effects of the Invention As detailed above, in the present invention, the holding member holds both sides of the sock attached to the template, such as the waist, so that the holding member does not slip against the sock like a conventional gripping member. The socks can be reliably pulled down and put on without any problems, and this is an excellent method that prevents mis-setting even with socks made of high elasticity and improves product yield. be effective.
