Description

[Detailed description of the invention] Automatic sock turning machine suitable for connection with sock linking machine [Technical field] This invention provides an automatic sock turning machine suitable for connection with a sock linking machine. Regarding.

[Background technology]

Sock turning machines of this type are known. These sock turning machines are equipped with a blade. Place the cylindrical leg of the sock, which is sewn together at the toe, over the braid, and It rotates in the opposite direction and presses the blade elastically from both sides. By the action of a pair of parallel reversing rollers, the sock is removed from the toe area. It is configured to be turned over sequentially.

Another conventional sock turning machine has a pair of upper turning rollers, generally isolated from each other. A pair of pull-out rollers are provided, and the pull-out roller is below the upper reversing roller. and a pair of socks or socks held by a gripper provided above the reversing roller. It is designed to be introduced into the gap between the pull-out rollers. The above blade has a pair of opposite blades. This reversing roller is installed above the reversing roller to cover the blade with the sock. When the roller closes and begins to rotate, it descends to a first stop position between two pairs of rollers; Then the pull-out roller closes and rotates so that the sock is pulled out of the blade. During this period, it continues to descend further.

In such conventional sock turning machines, the contact area between the rollers is Is there a serious problem in that it is limited to a common generatrix located on a horizontal plane that includes the axis of rotation? Ru. In this way, the contact area between the rollers or the generatrix is limited, so the impact on the socks is The pressure of the rollers used must necessarily be high. . Therefore, socks knitted with fine threads and embroidered socks with loose threads on the inside. loose loop knitting socks worn by lawn tennis players and basketball players Socks called ``terry socks'' can be turned over using a conventional sock inside-out machine. If you put it on the socks, the knitted fabric of those socks will be easily damaged.

This also applies to covers for rollers, especially reversing rollers.

In other words, if your socks are covered with fine threads, close your mouth tightly or close your mouth tightly. Since it is necessary to hold the rollers, the covers for the rollers also tend to wear out rapidly.

Also, it is very difficult to insert the blade into the pocket formed in the toe part of the sock. It is difficult to This is because the toe part released by the gripping tool is This is because it is easily bent toward the curved surface of the reversing roller.

Furthermore, since it is necessary to stop the blade midway, it is necessary to turn the sock inside out or invert it. The operating cycle is subtracted, children's socks, length 12 cm, force 15 cm, etc. There is also the issue that it is practically impossible to turn shorter socks inside out. .

A sock or a rectangular blade with different heights pressed elastically on both sides. There is also a publicly available sock inside-out or reversing machine that is configured to turn socks inside out by the action of two pairs of belts. It is knowledge. In this conventional device, the removal of the sock takes place after the sock inversion cycle. The lower belt moves or rotates in reverse and is pressed against the bottom of the blade. This is achieved by

With this device, the action between the knitted fabric of the sock that is being turned inside out, the braid, and the belt is possible. The specific pressure applied to the Never.

However, when feeding socks from the sock linking machine to the sock turning machine, this supply Because the functions they handle are inevitably complex, various problems are likely to occur.

Therefore, the present invention provides an automatic sock turning machine suitable for connection with a sock linking machine. This machine solves the problems with conventional sock turning machines, and when turning socks inside out, The purpose of the present invention is to provide an automatic sock turning machine with means for efficiently controlling the position of Toshito.

The conveying device that receives the socks from the sock linking machine and delivers it to the reversing device 2 is 1, 2, 3, and 11.

This conveyance device is composed of a gripper 26 that can be opened and closed and has two gripping members 27 and 28. has been done. The two gripping members 27 and 28 are arranged horizontally along the longitudinal direction of the gripping tool 26. They are rotatably connected to each other by a shaft 29 extending in the plane, and the Each clamping edge 27', 28' is supported so as to face a horizontal plane.

Typically, this gripper 26 is arranged above the shaft 29 by the gripping members 27, 28. It is held in the closed position by the action of a spring 30 interposed therebetween.

In this state, the respective clamping edges 27', 28' of the gripping members 27.28 are in contact with each other. This gripper 26 is in the open position, ie gripping member 27.2 8, each of the clamping edges 271, 28' are spaced apart from each other by This is achieved by operating the air cylinder 31 located below the port 29.

In the embodiment of the invention shown in FIGS. 1-10, the gripper 26 is A slide movable along a rod 34, 35 parallel to the vertical working surface containing the blade 3 It is fixed to the lower side projecting portion 32 of the moving body 33.

Said horizontal rods 34, 35 extend transversely to the upper belt pair 7 and the lower belt pair 8. The bracket attached to the front wall 4 of the storage casing It is attached to a tab-shaped overhanging support 36.

The air cylinder 37 housed in the storage casing l has the sliding body 33 connected to the horizontal rod 3. 4.35. The sliding body 33 is horizontally rotated like this. When moved along the rods 34 , 35 , the gripper 26 also moves relative to the reversing device 2 . It will be moved between the outer and inner positions. In addition, if the gripping tool 26 When in this position, this gripping tool 26 faces between the annular endless belts of the upper belt pair 7. In addition, the gripping edges 27' and 28' of the gripping members 27 and 28 of the gripping tool 26 are connected to the reversing brake. parallel to the vertical working surface of board 3. These gripping members 27, 28 are the gripping tools 26 is in the inner position, the grip attached to the sliding body 33 via the lower lateral extension 32 The clamping edge 27' of the holding member 27 is a brush against the vertical working surface of the reversing blade 3.

When the gripper 26 is in the outward position, the sock straight linking shown in FIGS. It now faces above the discharge end 40 of the machine 41. At this time, the toe area should be completely woven. The worn socks are attached to the belt 42 by a pair of springs (not shown or known in the art). The conveyor belt 42 cooperates with the sliding body 42a being pressed against the conveyor belt 42. It is. Note that the discharge end 40 of the sock linear linking machine 41 is connected to an air cylinder 42. b is driven in the direction away from the belt 42. . When the gripper 26 reaches this position, it is in the open state and is not connected to the reversing device 2. When the sock being transferred reaches the appropriate position relative to this gripper 26, it stops at the transfer stop. will be stopped.

The above-mentioned "appropriate position" refers to the position after the gripping tool 26 is in the closed state and moved to the inward position. Then, the toe portion of the sock is removed on one side of the suture line gripped by the gripper 26 in the open state. Pocket S (see Figure 2) formed in the It means the position of attention. Note that the vertical center plane of the reversing blade 3 is at the upper base at this time. It coincides with the vertical center plane of the belt pair 7 and the lower belt pair 8. This condition is the sole of the sock. This is also a necessary state in order to be able to return accurately.

Photoelectric element 4 provided at the discharge end 40 of the sock linking machine below the sliding body 42a 3 determines the above-mentioned "appropriate position", that is, the shoes are placed in the appropriate position. I am trying to detect the arrival of the bottom. In other words, as shown in FIG. 1 and FIG. If the fabric of the sock 44 transferred in this manner blocks the light from entering the photoelectric element 43, this photoelectric element 43 is activated.

Also, since socks come in various sizes, automatic socks can be used for any size sock. This photoelectric element 43 is connected to the unloading of the linking machine 41 so that the turning machine can operate satisfactorily. A small plate 45 whose position along the direction of movement of the gripper 26 relative to the end 40 can be adjusted It is installed. In other words, the position of the photoelectric element 43 is determined by the automatic sock turning machine. The gripping tool 26 can be adjusted along the moving direction according to the size of the socks to be handled. It has become.

Located in front of the front wall 4 of the storage casing 1 and below the lower belt pair 8, this Separated from the lower belt pair 8, the position of this sock is controlled when the sock is turned inside out. A stabilizing device is provided. This stabilizer is a vertical action of the reversing blade 3. It is composed of a pair of comb-like members 46 of the same configuration arranged symmetrically on both sides of the plane. child These comb-shaped members 46 extend perpendicularly to the front wall 4 of the storage casing 1 and , have the same configuration and are arranged symmetrically with respect to the vertical action surface. This comb-shaped member 46 As shown in FIG. It is fixed to the top end of a lever 47 rotatably mounted on a shaft 48. This place The wedge-shaped member 46 is housed within the storage casing 1 and is centered around the pivot shaft 48. The action of the air cylinder 49.50 rotates the lever 47 in the desired direction. It can be moved towards said vertical working surface of the diverting blade 3.

The minimum distance between the pair of comb-like members 46 is the same as that between the upper belt pair 7 and the lower belt pair 8. is provided to adjust the minimum interval between the facing running parts of the circular endless belt in It can be adjusted using an adjustment mechanism that is substantially similar to the adjustment mechanism described above. Sunawa As is clear from FIG. 5, there is an adjustment mechanism for adjusting the minimum interval between the comb members 46. is equipped with a scaled knob 52 facing outward from the storage casing 1. The housing is also provided with a notch that engages with the engaging member 54 fixed to the storage casing 1. The rod 51 also includes a biting member 53. This rod 51 is the spring 5 5, it is biased toward the left side in FIG. 56 is a ring nut , in order to pull it away from the lever 47 on one side (left side in Figure 5), on the other side (on the left side in Figure 5). The lever 47 on the right side is acted upon by the lever 47. ring nuts If the right side moves by t<-47 due to the action of 56, it will be pivoted on the pivot shaft 48. The movement is transmitted to the left side Leno<-47 via the sector gear 57.

A second photoelectric detector 58 is provided in the space between the lower heald pair 8 and the comb-shaped member 46. It is being This second photoelectric detector 58 is installed on one side of the vertical action surface of the reversing blade 3. , so as to project a horizontal light beam in a direction parallel to the front wall 4 of the storage casing 1. It has become.

The automatic sock turning machine according to the invention also includes a program control device 59. . This program control device 59 includes the magnetic detector 38, 39 and the photoelectric detector 43. ．． 58, drive motor 17, 17', and all the air cylinders mentioned above. However, there are programs suitable for coordinating the actions of these components. Since the ram is memorized, the sock 44 transferred from the sock linking machine 41 is stored. Is it possible to execute the desired sock inside-out operation cycle according to the program? can.

Regarding the operation of the automatic sock turning machine described above, please refer to Figures 6 to 1O. Explain in detail.

The state of the automatic sock turning machine according to the invention before the sock turning operation cycle is started. The situation is shown in Figure 1. Grasping the toe part of the sock 44 that has been sewn together with the gripping tool 26 The sock 44 is introduced between the members 27, 28 and the longitudinal sides of said gripping members 27, 28. When it comes to the center position with respect to the direction, the projection light of the photoelectric detector 43 is detected by the socks 44. The gripping tool 26 closes in response to the output signal from the photoelectric detector 43. , the sliding body 42a separates from the belt 42, and the sliding bodies 32 and 33 move to the sock reversing device 2. and move forward. The sliding body 32, 33 is moved forward to the sock reversing device 2 by the gripping tool. 26 faces between the annular endless belts of the upper belt pair 7, and the socks 44 face between the lower belt pair 8. It faces between the annular endless belts and stops when the comb member 46 is opened as shown in FIG. Ru. The gripping member 27 of the gripper 26 on one side of the vertical working surface of the reversing blade 3. Pocket S formed near the toe part of the sock held by 28 (Figure 2) Also, since the toe portion of the sock 44 or the gripper 26 is shifted in the lateral direction, Since it occupies a central position with respect to the gripping member 17.18, said pocket S It is placed directly below the lower end or leading end of the diversion blade 3. This sock has photoelectric detection Either cut off the light projected by the device 58 or use this photovoltaic device at this stage of the sock turning operation cycle. Detector 58 is inactive.

In this state, the piston of the air cylinder 37 that moves the sliders 32, 33 is magnetically This magnetic detector comes close to the magnetic detector 38 and activates this magnetic detector 38. An output pulse signal is supplied from output device 38 to program control device 59 .

In response to this output pulse signal from the program controller 59, the lower heald pair 8 The annular endless belt is in the closed state (the members of the annular endless belt are close to each other) At the same time, the comb member 46 of the stabilizing device also becomes closed, and the gripping tool 26 also closes. In the open state, the sliding bodies 32 and 33 return to their initial positions, and the gripping tool 26 comes to the outer position. , waits for the toe of another sock sewn by the sock linking machine 41 to arrive. I'm going to have a good time. As a result, the components 3.7.8.46 of the reversing device 2 or FIG. The state shown in is reached.

When the sliding body 42a returns to the sock linking machine 41, the magnetic detector 39 An output pulse signal is generated from the program controller 59, thereby activating the program controller 59.

The program control device 59 operates in response to the output pulse signal from the magnetic detector 39. Then, the annular endless belt of the upper belt pair 7 becomes closed, while the upper belt pair 7 and the lower belt pair 8 are run upward from the opposing running portions of the respective annular endless belts. It also operates the photoelectric detector 58 to move the reversing blade 3 in that direction. It will now be moved to the lowered position. Therefore, it is held by the comb member 46. The sock is pulled upward and covered with the reversing blade 3, and at the same time the socks are It will be turned inside out as if it were.

At this stage of the sock inside-out cycle, the action of the stabilizer comb 46 When the sock rises, a tensile force acts and stretches the sock straight, so the sock or heel area recesses and double elastic threads in Even if the folded part or cuff is formed with a reversing button This prevents erroneous engagement of the lead 3.

When the reversing blade 3 reaches the lowered position as shown in FIG. At that time, each of the annular endless belts of 7 and lower belt pair 8 is directed in the direction indicated by the arrow. the sock or the inversion brake along almost its entire length. This sock 44 is pulled up until it covers the door 3. However, the so-called wearing of socks When the opening opens the projection light path from the photoelectric detector 58, the light emitted from the photoelectric detector 58 is A force pulse signal is generated and this output pulse signal is supplied to the program controller 59. Then, the program control device 59 executes the following operations.

That is, the comb member 46 is opened, and after a short period of time, the socks are put on. The annular endless bell of the upper belt pair 7 moves upward from the opening to the reversing blade 3. While rotating the sock, raise the reversing blade 3 and pull the sock downward. The annular endless belt of the lower belt pair 8 is reversed so that it can be lowered.

In this way, while the sock is being pulled down from the reversing blade 3, the photoelectric detector 5 8, or by the sock 44 hanging downward as shown in Figure 0. Be cut off. Even so, the annular endless belt of lower belt pair 8 does not stop. , until the sock is completely pulled down and the projection optical path of the photoelectric detector 58 is opened. It is rotating in the direction indicated by the arrow in Figure 10.

When the projection optical path of the photoelectric detector 58 is opened as described above, the annular shape of the lower belt pair 8 While the rotation of the endless belt stops, the facing running parts of this circular endless belt are separated from each other. After a while, the next sock can be introduced as described above. this Repeat this cycle for the next sock. will be done. Note that while the above operation is being performed, the upper belt pair By rotating the circular endless belt 7, the lower belt pairs with the circular endless belt 8, and the socks can be placed on the reversing blade 3, and the annular endless belt of the upper belt pair 7 When the belt stops thereafter, the hem of the sock above the upper belt pair 7 is securely held. I can hold the sock completely inside out and take it out.

Since the automatic sock turning machine according to the present invention has the above-mentioned configuration, it has various effects and It has many advantages and is useful for practical use. That is, various annular endless The diameter of the rollers on which the belt is stretched is as small as 34 mm, for example. This pair of socks is often held between the facing running parts of the annular endless belt of the lower belt pair 8. What you can see from the clamping area between the surface running parts (approximately 22mm in the actual machine) do not have. Therefore, the sandwiched socks will not bend to one side. A descending inverting blade is formed on one side of the toe of the sock being inverted. It can be safely and securely inserted into a pocket.

Also, the contact area between the gripping edges 27' and 28' of the closed gripper 26 is Displacement (typically 5 aun) l transversely to the vertical working plane of the blade.

Because of the fact that the If the sock is held until the toe of the sock is gripped, use the reversing blade. It is possible to securely fit into this pocket.

In addition, the pressure when the facing running parts of the circular endless belt close each other is applied over a wide surface. and therefore the specific pressure acting on the sock is relatively small, so the sock No matter what kind of belt it is, it will not be damaged by the circular endless belt. Even if the circular endless belt itself wears out, ignore it. That's about as much as you can get.

On the outer surface of each of the aforementioned endless annular belts, a V-shaped groove is formed in the width direction along its entire length. The sock or the inside of the sock has a loose thread lining because it is formed to extend. Even if there is a V-shaped groove, the There is no risk of damage to the socks.

Furthermore, the time required to turn the sock inside out also depends on whether the reversing blade is in the raised position or not. There is no need to stop the movement on the way to and from the lowered position, so it is relatively short. Finish.

Additionally, there is a pair of identical lower belts that work together to turn the sock inside out, or reverse its direction of rotation. This is called a terry sock because it pulls the sock down. Even sock-like socks can prevent the sock from slipping.

Place the reversing blade 3 at its lower end or leading end (lower bell) and below the pair 8. When the downward movement of this reversing blade is stopped, the ring constituting the lower belt pair 8 The endless belt should not act on the sewn toe area of the sock, and There are benefits that can be functioned in minutes. Especially when it comes to the feet of socks, The knitting direction is the opposite of that of the toe area, so the shoes below the seam The loop thread will not be pulled to the right at the bottom.

The annular endless belts of the upper belt pair and the lower belt pair are on both sides of the reversing blade 3. It is desirable to drive the sock layer so that there is no relative displacement in the height direction. .

In addition, it is possible to firmly connect the comb-like member 46 and the lever 47 that supports each. This ensures that the correct tension is always applied to the socks, and that they are properly tensioned when turned inside out. In addition to being able to be fixed in place, the reversing blade or the heel of the sock can be caught This can prevent shoes from getting caught in the shoe opening. Supports the comb member By driving the lever with an air cylinder, the automatic sock turning machine of this invention can be used to turn socks of various thickness. You can also use it to turn your socks inside out.

This invention can also be used to turn children's socks inside out. However, in this case, children's Since the socks are shorter than adult socks, they can be held securely by the comb member 46. It is necessary to select the length of this comb-like member 46.

It goes without saying that it can also be applied to turning socks as small as about 8 cm inside out.

In this case, the photoelectric detector 58 is omitted, and the time required to turn the sock inside out is determined by the reversing blade. 3 is shortened, and the comb member 46 is moved closer to the lower belt pair 8. Once placed, the program controller 59 is configured as determined by a constant cycle. Just do it.

Removing the sock downwards is done by releasing the lower bell at the beginning of the sock turning cycle. The annular endless belt of upper belt pair 7 rotates in the same direction as the annular endless belt of upper belt pair 8. is stopped during the pulling down phase of the sock to prevent the lowering of the sock that has already been turned inside out. This can be easily achieved by applying a lot of braking.

The annular endless belt of the upper belt pair and the lower belt pair is placed on the vertical working surface of the reversing blade. Are you using an air cylinder to move them closer together or apart? Therefore, it is possible to run this circular endless belt against socks of various widths without the need of a skilled worker. The minimum spacing between rows can be easily adjusted. This requires a very It is easy and can also be done by the employee in charge of the sock linking machine. I'll come. In short, turn the corresponding graduated knob for each circular endless belt. Bye. By doing this, the minimum distance of the circular endless belt from the vertical working surface can be determined. It can be divided into sections.

Therefore, the automatic sock turning machine with the above-mentioned effects and advantages is very reliable and Moreover, it is clear that it is versatile and can be easily controlled even by non-experts. be.

Note that other modifications and variations of this invention are possible.

For example, as shown in Figure 11, a sock circular linking machine 41'' is used to automatically turn socks inside out. When connecting the machine, the gripping member 27'28' of the gripping tool 261 is connected to the sliding body 3. 2.33, a vertical pin 60 is attached to this sliding body 32.33. The air cylinder is pivoted through the The ring shape of the linking machine 41' shown by the imaginary line in FIG. From the sock receiving position in part 62 of the rotary dial, as shown by the solid line in FIG. As shown above, move the blade to a position almost parallel to the vertical working surface of the reversing blade. That's fine.

In this case, the mutually pinching edges 27', 28' of the gripper 26' support the vertical pin 60. In accordance with the curvature of the annular dial 62 to be It is curved in the same way as the plate 45 that holds the electric detector 43.

In this case, the adjustment of the position of the photoelectric detector according to the width of the sock is performed by connecting the plate 45 and the photoelectric detector. This can be achieved by moving the container along the outer periphery of the dial 62.

In addition, as another modification, the area between the lower belt pair 8 and the comb member 46 may be The photoelectric detector 58 shown in FIG. 1 is not necessarily required and may be omitted. Especially small When using the automatic sock turning machine of this invention to turn small socks inside out, It is sufficient that the filter photoelectric detector 58 is not used. In this case, as mentioned above, Configure the program controller to take a certain amount of time to return or a constant cycle. .

Furthermore, the air cylinder 6 that controls the movement of the reversing blade 3 is provided with the air cylinder 6 shown in FIG. , the reversing blade 3 reaches the raised position, the lowered position, or an intermediate position between the two. magnetic detection that provides each output signal to the program controller 59 representing the 63,64,65 may be provided.

Similarly, for the air cylinder 37 that drives the sliding bodies 32 and 33, the intermediate magnetic A gas detector 66 may also be provided. These intermediate magnetic detectors 65,66 are The system control device 59 controls either the gripping tool 26 or the reversing blade 3, or both. It can also be used to cause some movement before reaching its end position. Wear.
