Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock holding device for receiving a group of socks from a large number of toes by the sock extracting device and receiving the socks from the sock extracting device for a certain period of time.

[0002]

2. Description of the Related Art Generally, in the process of manufacturing socks such as pantyhose and tights, the socks inserted into a large number of foot molds after the processes such as knitting, sewing and dyeing are completed are heated by a finishing machine. Finishing treatment such as set is given, then it is simultaneously extracted from the foot mold by the automatic extraction device,
Next, after being accumulated in a uniform bundle state by the accumulating and retaining device and kept in that state for a certain period of time, it is sent to the next step such as a packaging step. Conventionally, as the above-mentioned accumulation holding device, one disclosed in Japanese Patent Publication No. 3-25542 has been proposed.
As shown in FIG. 20, this is composed of a stacking device 71 and a holding device 70. The stacking device 71 is
A set of two collecting arms 50 on which bundled socks 66 are collected
a, 50b, and push plates 51a, 51b for pushing the bundled socks 66 accumulated on both the accumulation arms 50a, 50b forward (indicated by arrow Z). The collecting arms 50a and 50b are attached to a sliding base 53 provided on the front surface of the extracting device, and the sliding movement of the sliding base 53 in the left-right direction (indicated by an arrow Y) causes the inside of the extracting device to move. It moves between the limit switches 54 provided at two predetermined positions located on the right side and the limit switches 55 provided at two positions at the left and right ends of the extracting device. The distance between the inner limit switches 54 is set to be the same as the distance between the leading end portions of the hooking arm pairs 52a and 52b described below. The extruded plates 51a, 51
b is provided at the front end of a slide cover (not shown) provided so as to cover a part of both the integrating arms 50a and 50b. This slide cover is provided with a slide body 57 having a groove 56 extending in the left-right direction at its rear end, and a roller 59 formed at the rear end of the swing arm 58 is loosely fitted in the groove 56. There is. The swing arm 58 is connected to a one-rotation motor 61 via a crank lever 60, and the rotation of the one-rotation motor 61 causes the swing arm 58 to swing around a shaft 62 as a base point. The roller 59 at the rear end of the arm 58 reciprocates once in the front-rear direction. As a result, the slide cover slides back and forth on the collecting arms 50a and 50b, and when the slide covers move forward, the push plates 51a and 51b are moved.
b pushes the bundled socks 66 on the collecting arms 50a and 50b forward.

On the other hand, the holding device 70 includes a drive unit 63.
The drive unit 63 is provided with a support column 65 rotatably supported by a bearing 64, and four pairs of latching arms 52a and 52b radially attached to the upper end of the support column 65. The hooking arm pairs 52a and 52b are formed in a substantially V shape with their tip portions formed in parallel. The column 65 is connected to a driving means and a positioning means housed in the driving portion 63, and is intermittently rotated by a quarter rotation by the driving means and the positioning means. As a result, the ends of the pair of latch arms 52a and 52b are positioned and temporarily stopped in a state of facing the front ends of the stacking arms 50a and 50b that have moved to the position of the inner limit switch 54, and stopped for a certain period of time. Later prop 6
5 rotates one quarter turn, and the adjacent latch arm pair 52a, 52b
Each of the tips is positioned at the front ends of the collecting arms 50a and 50b.

When socks are collected and held by using this device, first, the bundled socks 6 are extracted from the extraction device on the accumulation arms 50a and 50b and are bundled into a bundle.
Take 6 Then, the collecting arms 50a and 50b on which the bundled socks 66 are hooked are moved to the position of the inner limit switch 54 (that is, the hooking arm pairs 52a and 5 of the holding device 70).
2b is moved to a position where the tip end is positioned) and temporarily stopped, and in this state, the one-rotation motor 61 is rotated to move the pushing plates 51a and 51b forward. As a result, the bundled socks 66 on the stacking arms 50a and 50b are pushed forward, and the bundled socks 66 are sent to the parallel portions of the tips of the hooking arm pairs 52a and 52b and are stretched over them. After the bundled socks 66 have been fed in a predetermined number of times, the support 6
5 rotates one quarter turn and the adjacent pair of empty latch arms 52a, 5
The respective tips of 2b are positioned at the front ends of the collecting arms 50a, 50b.

[0005]

However, in the above integrated holding device, since the latching arm pairs 52a and 52b are attached in a substantially radial shape, there is a problem that the device is large and a large installation space is required. . In addition, in this device, when the bundled socks 66 are hung from the collecting arms 50a and 50b to the hanging arm pairs 52a and 52b, the pushing plate 51 is used.
Since the bundled socks 66 are pushed out by the a and 51b, the tips of the accumulating arms 50a and 50b and the hanging arm pairs 52a and 52
There is also a problem that the bundled socks 66 are caught in a gap formed in a portion facing the tip of b, and the bundled socks 66 are likely to be broken or wrinkled. Furthermore, the above-mentioned latching arm pair 5
Since 2a and 52b are bent and formed substantially in the center, the bundled socks 66 hung over the parallel portions of the hooking arm pairs 52a and 52b are pushed out from the collecting arms 50a and 50b. There is a problem that folding wrinkles are likely to occur even when the bundled socks 66 are pushed into the back side of the arm and slide through the bent portion. To avoid this, if you lengthen the parallel part and cross it over only the parallel part,
Further, there is a problem that the device becomes large. Besides,
In order to increase the amount of the bundled socks 66 to be held, when the amount of the bundled socks 66 to be hung on the hanging arm pairs 52a and 52b is increased, the first or second pair of hanging arms 52a, 52a,
When a large amount of bundled socks 66 is hung on 52b, the load applied to the support column 65 becomes unbalanced, which causes a problem that it becomes difficult for the support column 65 to rotate smoothly. There is a limit to the increase. Further, the stacking means for stacking the bundled socks 66 on the collecting arms 50a and 50b from the extracting device is not shown at all.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a sock holding device which is small in size and which is unlikely to cause wrinkles or the like in the socks.

[0007]

In order to achieve the above object, the present invention is a means for withdrawing the socks from a large number of toes each having socks inserted therein, and a predetermined interval left and right. A pair of supporting members to be disposed, a bridging means for bridging the group of socks extracted by the extracting means in a state of being stacked horizontally on the supporting member, and a descending means for lowering the supporting member. A holding device provided in front of a sock extracting device provided, wherein a group of socks are laid across in a horizontal manner from a supporting member disposed below the supporting member and lowered by the lowering means. A pair of left and right arms for receiving, a holding conveyor arranged in front of this arm, a high position higher than this holding conveyor and higher than the lowermost position of the supporting member, and a lower position lower than the holding conveyor. Between the arm raising and lowering means for raising and lowering the arm by means of, a holding body for holding the arm raising and lowering means, a rear position for positioning the arm below the support member, and a front position for positioning the arm at the rear end of the holding conveyor. The holding body moving means for moving the holding body back and forth at, the driving means for intermittently advancing the holding conveyor, and the forward position by advancing the holding body from the state in which the holding body is in the rear position and the arm is in the high position. Then, the arm is lowered to the low position, and then the holding member is retracted to the rear position, and then the arm is moved to the high position.

[0008]

That is, the sock-holding device of the present invention removes socks from a large number of foot molds and holds them on a holding conveyor as follows. That is, first, the socks extracted from the foot form by the extracting means are stacked in a bundle and are laid across the supporting member in a horizontal shape. When the supporting member descends, the bundled socks are horizontally stretched over the arm located below the supporting member and above the holding conveyor. The arm thus receiving the bundled socks is advanced above the rear end of the holding conveyor and then lowered to be positioned below the holding conveyor. Hand over to the holding conveyor,
Next, the arm is retracted to the original position and raised as it is to return the arm to the original position. Then, a series of these operations are repeated a plurality of times to advance the holding conveyor by a predetermined distance in a state where a group of socks are hung over the holding conveyor a plurality of times.

As described above, since the bundled socks are hung on the holding conveyor and held, the radial hooking arm pairs 52a and 52b, which are required in the conventional example, are not required, and the apparatus is compact. And requires less installation space.
Further, in this device, the bundled socks are laid horizontally from the support member to the arm, and the arm is lowered from above the rear end of the holding conveyor so that the arm is hung from the holding conveyor. ing. For this reason, the sock does not suffer from creases or creases when it is passed over.
Moreover, the bundled socks are stacked by repeating this bridging a plurality of times, and folding wrinkles and the like do not occur during the stacking. Further, the bundled socks hung on the holding conveyor is configured to move by the forward movement of the holding conveyor, so that there is no such thing as sliding through the bent portion as in the conventional example, Wrinkles do not occur. Also, when increasing the amount of socks to be held, increase the amount of socks to be hung on the holding conveyor (that is, increase the number of times that the bundled socks are hung on the holding conveyor by the arm while the holding conveyor is stopped). By doing so, the amount of socks that can be easily held can be increased. Moreover, in this device, the bundled socks are laid across from the support member to the arm in a crosswise manner, and the arm is hung from above the rear end of the holding conveyor to be hung from the arm to the holding conveyor. The socks do not break or wrinkle. Further, in the sock holding device of the present invention, the socks that are extracted from the foot form by the extraction means and stacked in a bundle are laid horizontally across the support member, and the support member is lowered to lower the support member. Since it is hung horizontally across the arm located below the holding conveyor and above the holding conveyor, creases and the like are unlikely to occur during this hanging.

In the sock holding device of the present invention,
A pair of left and right support shafts are provided on the arm elevating means, the rear end of each arm is rotatably attached to each support shaft, and a biasing means for biasing each arm inward is provided between both arms. When a pair of left and right abutting members are provided in front of each arm and immediately behind the holding conveyor, when the holding body is advanced from the rear position with both arms in the high position. When the arms are abutted against the inner surface of each arm and each arm is pivoted outward to open the tip side of each arm, when the arm around which the bundled socks are stretched is advanced at a high position. The arm comes into contact with the abutting member and the tip side thereof is pushed outward, and the left and right hanging ends of the bundled socks suspended on the arm are also pushed outward together with the arm. For this reason, when the bundled socks are hung on the holding conveyor a large number of times so that the bundled socks are laid over the holding conveyor a plurality of times, the bundled socks that have already been hung are then hung up next. Since it becomes difficult for the hanging ends of the bundled socks to come into contact with each other, the socks do not fold or wrinkle, and the amount of bundled socks to be held can be further increased.

In the sock holding device of the present invention,
A substantially L-shaped rod-shaped body is attached to the holding body, and a lateral side portion extending along the arm of the L-shaped body of the rod-shaped body is projected to one side of the left and right sides of the pair of left and right arms. When the bundled socks are hung on the arm, the one end of the bundled socks provided with the rubber portion is held by the lateral side of the rod-shaped body while being supported. It becomes possible to hang it on the conveyor. For this reason, even when the bundled socks are laid over the holding conveyor a plurality of times and the rubber portion (thicker than other portions) is raised by a plurality of times of stacking, this Since the raised portion does not come into contact with the suspended end of the bundled sock to be hung next, the bundled sock does not have folds or wrinkles. Therefore, the amount of bundled socks to be held can be further increased.

Next, the present invention will be described in detail based on embodiments.

At the same time, the delivery lever 27 attached to the upper holding body 4a also moves forward, so that the rubber portion 35a of the bundled socks 35 supported by the upper inclined portion 26b of the chevron cover 26 is supported by the delivery lever 27. To be done.
Next, as shown in FIG. 14, when the holder 4 is at the front end position and the delivery arm 3 descends to reach the lower end position (that is, the position below the upper surface of the stock conveyor 2), both arm portions 3a open. The bundle-shaped socks 35 are laid horizontally on the stock conveyor 2 while the rubber part 35a of the bundled socks 35 is supported by the delivery lever 27 while being closed while being separated from the large diameter part 5a of the pin 5. After that, Fig. 15
As shown in FIG.
Reach the rear end position. At this time, the delivery lever 27 also retreats as the delivery arm 3 retreats, and the rubber portion 3 of the bundled socks 35 supported by the delivery lever 27.
The support of 5a is released, and the bundled socks 35 are hung on the stock conveyor 2.

Further, the above series of operations is repeated a plurality of times (three times in this embodiment). That is, first, in FIG.
As shown in FIG. 18, the bundled socks 35 are further stretched over the rear end of the stock conveyor 2 (in the figure, it has already been stretched twice) on which the bundled socks 35 are stretched. After that, in a state where the bundled socks 35 are laid over the stock conveyor 2 three times, the stock conveyor 2 is advanced by a distance substantially the same as the width of the bundled socks 35.
An empty space having substantially the same width as the bundle of socks 35 is provided at the rear end of the stock conveyor 2, and the next bundle of socks 35 is hung in this space.

As described above, in this sock holding device, since the bundled socks 35 are hung and held on the stock conveyor 2, the radial hooking arm pairs 52a and 52b, which are required in the conventional example, are provided. It is not necessary, the device is downsized, and the installation space is small. In addition, the bundled socks 35 are horizontally crossed over the delivery arm 32 from the delivery member 32b, and the delivery arm 3 is lowered from above the rear end portion of the stock conveyor 2 so that the delivery arm 3 moves from the stock conveyor 2 to the stock conveyor 2. I'm trying to get it over. For this reason, at the time of this handing over, the bundled socks 35 are not broken or wrinkled. Further, the bundled socks 35 are stacked by repeating this bridging a plurality of times, and folding wrinkles and the like do not occur during the stacking. Furthermore, since the bundled socks 35 hung on the stock conveyor 2 are adapted to move as the stock conveyor 2 moves forward,
Unlike the conventional example, it does not slide through the bent portion and does not cause wrinkles or the like. Further, even when the amount of socks to be held is increased, the amount of the bundled socks 35 to be hung on the stock conveyor 2 is increased (that is, the stock conveyor 2).
The number of socks to be easily held can be increased by increasing the number of times the bundled socks 35 are hung on the stock conveyor 2 by the delivery arm 3 in a state where the socks are stopped.
Further, in the sock holding device of the present invention, the extracting device 3
The bundled socks 35 taken out from the foot mold 39 by the 7 and hung horizontally on the hanging member 32b are lowered below the hanging member 32b by the lowering of the hanging member 32b. Since the delivery arm 3 located above is laid horizontally, it is unlikely that folds or wrinkles will occur during this delivery. Further, in this embodiment, unlike the conventional example, the latching arm pairs 52a and 52b do not rotate, and the safety is high. In addition, since the work of removing the bundled socks 35 from the stock conveyor 2 can be performed while the apparatus is operating, there is an advantage that the operation efficiency is improved.

Further, in the above embodiment, when the delivery arm 3 on which the bundled socks 35 are stretched is advanced, both arm portions 3 are moved.
a is pushed open by the arm opening pin 5, and the left and right ends of the bundled socks 35 are pushed outward together with both the arm portions 3a, so that the bundled socks 35 are hung on the stock conveyor 2 more times. Even in this case, the ends of the bundled socks 35 hanging from both ends of the delivery arm 3 do not come into contact with the bundled socks 35 already hung on the stock conveyor 2, so that the bundled socks 35 are broken or wrinkled. It is possible to further increase the amount of the bundled socks 35 to be held.

Further, in this embodiment, when the bundled socks 35 are hung over the stock conveyor 2 a plurality of times, the rubber portion 35a becomes thicker and thicker than other portions of the bundled socks 35. The upper inclined portion 26a of the chevron cover 26
Also, it is arranged to be hung on the stock conveyor 2 while being supported by the transfer arm 27. For this reason, since it does not come into contact with the raised rubber portion 35a of the bundled sock 35 that has already been hung on the stock conveyor 2, the bundled sock 35 is not broken or wrinkled. Therefore, the amount of the bundled socks 35 to be held can be further increased.

In this embodiment, a group of socks is divided into two groups in the extracting device 37 to form two bundles of socks 35, and two holding devices are provided in front of the extracting device 37. Although two bundles of socks 35 are held respectively, one bundle of socks 35 is used in the extracting device 37.
May be formed, and the bundled socks 35 may be held by one holding device.

[0030]

As described above, according to the sock holding apparatus of the present invention, since it is hung on the holding conveyor and held, the radial hooking arm pair 5 which is required in the conventional example is provided.
2a and 52b are not required, the device is downsized, and the installation space is small. Further, in this device, the bundled socks are laid horizontally from the support member to the arm, and the arm is lowered from above the rear end of the holding conveyor so that the arm is hung from the holding conveyor. ing. For this reason, the sock does not suffer from creases or creases when it is passed over. Also, by repeating this crossing over a plurality of times, the bundled socks are stacked,
No wrinkles or wrinkles occur when stacking. Further, the bundled socks hung on the holding conveyor is configured to move by the forward movement of the holding conveyor, so that there is no such thing as sliding through the bent portion as in the conventional example, Wrinkles do not occur. Also, when increasing the amount of socks to be held, increase the amount of socks to be hung on the holding conveyor (that is, increase the number of times the bundled socks are hung on the holding conveyor by the arm while the holding conveyor is stopped). By doing so, the amount of socks that can be easily held can be increased. Moreover, in this device, the bundled socks are laid horizontally from the support member to the arm, and the arm is lowered from above the rear end of the holding conveyor to be hung from the arm to the holding conveyor. The socks do not break or wrinkle. Further, in the sock holding device of the present invention, the socks that are extracted from the foot form by the extraction means and stacked in a bundle are laid horizontally across the support member, and the support member is lowered to lower the support member. Since it is hung horizontally across the arm located below the holding conveyor and above the holding conveyor, creases and the like are unlikely to occur during this hanging.
