Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for collecting and holding socks in a uniform bundle, and more specifically, for finishing socks inserted into a number of lasts of a sock finishing machine. After the processing is completed, the socks are pulled out all at once using a sampling device, and then the group of socks is
This invention relates to a sock collecting and holding device that separates and collects pairs of socks into uniform bundles and holds them in the same state for a certain period of time.

(Prior art) In the past, socks inserted into many lasts were passed through a sock finishing machine for finishing treatment, and then
A device was proposed (Japanese Patent Publication No. 56-4665, etc.) which performs simultaneous sampling using an automatic sampling device as disclosed in Publication No. 5036, and collects the extracted socks into a uniform bundle. has been done. As shown in FIGS. 8 and 9, this device includes a gripping plate P that picks out a group of socks H from a large number of lasts of a sock finishing machine and conveys them to a predetermined position, an accumulating arm 1, and the accumulating arm 1. It is equipped with a push-out plate 2 that slides on the arm 1, and a group of socks H pulled out from the last of the foot by the gripping plate P are shown in FIG. 9a→
They are superimposed and transferred onto the collecting arm 1 in the order b→c. Therefore, the bundle of socks H hanging with the middle part hooked on the collecting arm 1 is pushed out toward the end of the collecting arm 1 by the pushing plate 2, and is pushed forward. The bundles are arranged in order and accumulated.

However, in this accumulation processing device, the amount of accumulation is limited to a small amount, so operations such as removing socks from the accumulation arm are frequently required, which places a heavy burden on the operator. Therefore, the present applicant has proposed a device (Japanese Patent Laid-Open No. 61-229764) that sequentially receives and holds bundles of socks accumulated in the accumulation processing device. This device will be briefly described based on FIG.
1, and a rotation drive device 62 that can intermittently rotate the sock holding portion 61 by the angle between the two adjacent latching arms 60. As a result, the plurality of radial hanging arms 60 move one after another to the sock receiving position, that is, to the position facing the tip of the collecting arm 1, and receive the socks H accumulated in a bundle (arrow Z). Hold it in a hanging state. When one latching arm becomes full, the sock holding portion 61 is rotated by a predetermined angle (45 degrees in the illustrated example), and the next latching arm is moved to the receiving position.

(Problems to be Solved by the Invention) The above-described sock accumulating device and holding device automatically accumulate the socks after the finishing process into a uniform bundle with the toe portions aligned, and keep the socks in the same state. It was possible to maintain the same position for many times longer than conventional methods without requiring human intervention.

However, all of these devices are intended for long socks such as pant-tight stockings, and are not suitable for over-knee stockings, high socks,
It was not possible to use socks, etc., which were shorter in appearance than panty socks. In other words, when trying to accumulate these socks, as described above based on FIG. As a result, the person ends up slipping out.

Therefore, it has been considered to reduce the number of socks to be processed per operation of removing socks, but this would reduce the processing efficiency and is unsuitable. Furthermore, when using two accumulation arms to separate the socks extracted from the last into two pairs and accumulate them, subsequent handling such as collection of the accumulated socks becomes complicated. If this were to be applied, one holding device would be required for each accumulation arm, which would take up a large amount of space, leading to the following problems.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a device that can achieve the extremely rational accumulation and retention achieved in long socks in short socks.

(Means for Solving the Problems) In order to achieve the above object, the apparatus of the present invention has the following configuration.

That is, a sock extraction device is installed in front of a sock extraction device that simultaneously pulls out a group of socks that have been inserted into a plurality of lasts, and separates two pairs of socks pulled out from the lasts and collects them in a bundle. an accumulating device comprising a set of accumulating arms and a pushing plate that slides on the accumulating arms; and a holding device provided in front of the accumulating device for sequentially receiving and holding bundles of socks sent out from the accumulating arms. The holding device includes a holding portion having a plurality of pairs of two latching arms arranged in a radial manner, each pair of two latching arms having distal end portions parallel to each other, and a holder for receiving socks to be delivered to the pair of latching arms a predetermined number of times. and a rotation drive means for intermittently rotating the holding part by an angle of (360 degrees/number of pairs of latching arms), and the accumulating device has a rotation driving means for intermittently rotating the holding part by an angle of (360 degrees/number of pairs of latching arms), and the accumulating device has a rotation driving means for intermittently rotating the holding part by an angle of (360 degrees/number of latching arm pairs), a sensing means for sensing that the distal end of the collecting arm has come to a position opposite to the parallel distal end of the pair of locking arms of the holding device; control means for stopping the pair of collecting arms at that position by sensing a predetermined number of times, and feeding the socks from the collecting arms to the pair of latching arms of the holding device when the collecting arms are stopped; The main purpose of this document is to have:

(Function) As described above, the device of the present invention sequentially removes two socks that have been removed all at once by the removal device after finishing the finishing process.
They are separated into sets and collected into a uniform bundle on two collecting arms, and after this operation is repeated a predetermined number of times, the ends of the two collecting arms are latched onto each set of two by a holding device. At the same time as facing the tips of the pair of arms, a pusher plate sliding on the collecting arm is activated to push out a group of accumulated socks in the same state onto the pair of latching arms, and on the opposite side of the latching arms, the socks are fed. Hold the worn socks in a dangling position. However,
When this feeding operation has been performed a predetermined number of times, the holding portion is rotated by a predetermined angle to move the next pair of empty latching arms to the sock receiving position, and the same operation is repeated. Therefore, the operations of extracting, stacking, and holding socks can be continued without any human intervention until all pairs of latching arms of the holding device are filled with socks.

Furthermore, since the stacking operation is performed at two locations using a set of two stacking arms, it can be applied not only to long socks but also to short socks. Further, when two types of socks of different colors and types are divided into groups and inserted into the last of the foot for processing, it is possible to accumulate and hold the socks in a separate state.

(Example) Hereinafter, an example of the apparatus of the present invention will be described in detail based on the drawings.

FIG. 1 is an overall explanatory diagram of a sock collecting and holding device according to the present invention, which consists of two parts: a collecting device M and a holding device N. The accumulating device M has two accumulating arms 1a, 1b protruding from the front thereof, and extrusion plates 2a, 2 that slide on the accumulating arms 1a, 1b.
b, and two accumulating arms 1a, 1 which perform the same operation as the sock accumulating processing device described above based on FIG.
b. In other words, after finishing the finishing process, the group of socks pulled out all at once by the sock extraction device is separated into two pairs (the number of socks to be extracted is
In the case of 30 sheets, 15 sheets each) are separated and stacked on two stacking arms 1a and 1b on the left and right.

Next, the holding device N will be explained based on FIG. 2, which is a front view of one embodiment thereof, and FIG. 3, which is a plan view thereof. This holding device N includes a driving part 4 provided at the center of a base 3, and a plurality of pairs of two latching arms 6a, 6b at the upper end of a column 5 projecting upward from the driving part 4. A sock holder 7 is attached with 6a, 6b, . . . arranged radially.

The latching arm members 6a and 6b are made of stainless steel, plastic, or other materials and are made into a pair of rod-shaped or tubular pieces, and their tips are deformed into a V-shape so that they are parallel to each other. Four sets of socks are attached to a mounting plate 8 provided in the center of the sock holding part 7 in a radial manner. Further, each of the pair of locking arms 6a, 6b is provided with a sock stopper S at the root portion thereof. FIGS. 4a and 4b are an enlarged plan view and a front view of the mounting portions of the pair of latching arms 6a and 6b, and the upper surface of the mounting plate 8 has a mounting boss 9 provided with a threaded leg 9a. ,9,...
are provided as many as the number of locking arms, and are fixed by screwing nuts 9b onto legs 9a that pass through the mounting plate 8 and the stopper 10. One end of an arm fixture 11 consisting of a pair of left and right plates with an L-shaped cross section is pivotally attached to the boss 9 by a bolt 11a, and the base 6c of the pair of latching arms 6a, 6b is fixed to this arm. It is secured by bolts 11b, 11b while being clamped by tool 11. Further, a fixing bolt 8a for tightening the arm fixture 11 and an adjusting bolt 8b for lifting the arm pair 6a, 6b from below are screwed onto the mounting plate 8.
With this adjustment bolt 8b, the arm pair 6a, 6
b is projected upward by an angle α (usually 3 to 10 degrees) with respect to the horizontal. This mounting angle α can be freely adjusted by adjusting the bolts 8a and 8b.

The support column 5 includes a pair of upper and lower bearings 21a of the drive unit 4,
21b, and a brake pulley 22 is fixed to the lower end thereof. A friction belt 23 is hung on the brake pulley 22, and the frictional force between the brake pulley 22 and the friction belt prevents play in the rotational movement of the support 5. Also, a positioning circle is provided in the middle of the support 5. A plate 24 and a ratchet wheel 25 are attached, and the upper surface of the positioning disc 24 is provided with engaging recesses 24a corresponding to the number of locking arm pairs 6a, 6b, and a positioning device 26 is provided on the outer periphery. It is provided. As shown in FIGS. 5a and 5b, the positioning device 26 includes a support 27 fixed to the machine frame 4a and a positioning pin 28 supported vertically and slidably by the support 27. The lower end of the positioning pin 28 is connected to the engagement recess 24.
The pin 28 is formed into a conical shape that engages with the pin 28, and is provided with a spring 29 on the outer periphery that presses the pin 28 downward. Further, a stopper member 30 that comes into contact with the lower support arm 27a of the supporter 27 is fixed to the intermediate portion of the positioning pin 28, and the spring 29 is connected to the stopper member 30 and the supporter 27a.
7 and the upper support arm 27b. A vertical shaft 3 that hangs downward is attached to the protruding end of the lever 31 that protrudes laterally from the stopper member 30.
2 are integrally provided, and a roller 33 is attached to the lower end of the vertical shaft 32.

Further, the ratchet wheel 25 is provided integrally with the lower surface of the positioning disc 24, and is an engagement lever pivotally connected to a rotary lever 40 that is independently rotatably supported around the support column 5. A pawl 41 engages with this. Note that this engaging claw 41 is always urged in the engaging direction by a spring 42. A lifting block 43 having an inclined surface 43a and a flat surface 43b is provided on the upper surface of the tip of the rotary lever 40, and a piston rod 44a of an air cylinder 44 is connected to the lower surface of the tip.

FIG. 6 is an operating circuit diagram of this holding device N, in which LS-1 is the piston rod 4 of the cylinder 44.
Limit switch, LS that detects the protruding end of 4a
-2 is a limit switch that detects the feeding of socks. However, the socks were sent out three times and LS-
When 2 is turned on three times, the solenoid valve MgV for cylinder 44 extension is activated by the stepping relay.
When turned on, the piston rod 44a of the cylinder 44 moves forward and rotates the rotary lever 40 in the direction of arrow X. At this time, the engaging claw 41 is connected to the ratchet wheel 2.
It slides over the teeth of No. 5 and engages with the teeth on the back side.
Also, the roller 33 on the vertical shaft 32 lifts the lifting block 4.
3 and reaches the plane 43b, the vertical shaft 32 and the positioning pin 28 are lifted as a unit, and as a result, the positioning pin 28
comes off from the engagement recess 24a of the positioning disc 24,
This allows the disk 24 to rotate.

When the tip of the piston rod 44a of the cylinder 44 reaches its protruding end, the limit switch is activated.
When it comes into contact with LS-1, the solenoid valve MgV is switched, the cylinder 44 retreats to its original contracted state, and the rotary lever 40 rotates in the opposite direction of the arrow X. At this time, the engaging pawl 41 is engaged with the teeth of the ratchet wheel 25, so the ratchet wheel 25
is rotated in the opposite direction of the arrow X together with the positioning disc 24. The rotation angle of the positioning disk 24 is an angle β obtained by dividing 360 degrees by the number of locking arm pairs (360÷4=90 degrees in the illustrated example).
That is, when the piston rod 44 moves forward once, the engaging claw 41 moves backward by the number of teeth corresponding to 90 degrees, and when the piston rod 44 moves backward, the roller 33 rolls off the lifting block 43, so that the positioning pin 28 moves downward, and the positioning disc 24
The stopping position of the disc 24 is determined by engaging with the next engaging recess 24a. In this way, the sock holder 7 on the upper part of the column 5 is rotated by 90 degrees, and the adjacent pair of empty latching arms 6a, 6b are moved to the sock receiving position, and receive the next bundle of socks H. That will happen.

The device of the present invention is arranged so that the tips of the pair of two latching arms 6a, 6b of the above-mentioned holding device N are butted against the tips of the two accumulation arms 1a, 1b of the accumulation device M. However, if the two collecting arms 1a, 1b are to be fed out at both left and right ends apart from each other, the pitch between the pair of locking arms 6a, 6b will inevitably become wider. This results in unnecessary space being required. Therefore, in the present invention, the distal ends of the collecting arms 1a and 1b are temporarily stopped in a state where they are opposed to the distal ends of the pair of latching arms 6a and 6b of the holding device N, which are made to have suitable dimensions, to perform feeding. The operation is performed by sequence control as shown in FIG.

The sock feeding mechanism in the accumulating device M has a first
As shown in the figure, extrusion plates 2a and 2b are provided at one end of a slide cover (not shown) that is slidably engaged to cover a portion of the accumulation arms 1a and 1b, and the swinging arm 101 is provided at the other end. A slide body 104 is provided having a groove 103 that engages with a roller 102 provided at one end. Reference numeral 105 is a crank lever, and a sliding base 106 fixes the collecting arms 1a and 1b and reciprocates left and right (in the direction of arrow Y).
A slide piece 107 is attached to the swing arm 101, one end of which is fixed to the motor shaft of a one-rotation motor MTR1 fixed via a motor bracket (not shown), and a slide piece 107 attached to the other end. It is engaged in the elongated hole 108. In other words,
Motor MTR1 is driven by crank lever 105
clockwise and rotate the swinging arm 101 to the axis 1.
A rocking motion will be performed using 09 as the base point,
This causes the slide cover to move to the accumulation arm 1.
The pushing plates 2a, 2b push out the socks on the collecting arms 1a, 1b forward by sliding movement on the collecting arms 1a, 1b.

However, in the present invention, the existing limit switches LS-
In addition to 3, a limit switch LS-S for stopping midway is provided inside it (position B). Its operation is as shown in the circuit diagram (Fig. 7), motor MTR2
When the sock rotates and the pulled socks are collected by the mechanism shown in FIG. 9, the two collecting arms 1a and 1b each move in the direction back to position A, but a When the halfway stop limit switch LS-S is turned on, the accumulating arm 1 that is moving

The set time is the time required to send the socks from the collecting arms 1a, 1b to the pair of latching arms 6a, 6b, and is usually 3 to 4 seconds. After the time is up, the timer T _S contact turns ON and the motor

RT turns on. Of course, the feed-out interval can be changed from 1 to 12 depending on the wiring, and depending on the type of socks, the feed-out interval can be changed as needed from 1 to 12.
It is also possible to accumulate the material once at a time, that is, to stack it four times, and then send it out. The timer RT is provided in consideration of the possibility of overrun due to inertia when the collecting arms 1a and 1b each stop at the B position, and is used to delay the delivery of socks by the time set by the timer RT. Therefore, a slight delay, that is, a momentary delay, is sufficient. Further, MTR1 and MTR1' are left and right sock feeding motors, respectively, and operate based on the same mechanism as that described above with reference to FIG.

Note that the collecting arms 1a, 1b are formed to be slightly thicker than the pair of hanging arms 6a, 6b, so that socks can be transferred smoothly without causing problems due to slight errors in the timer. Further, the number of the pair of latching arms 6a, 6b of the holding device N is not necessarily limited to eight (four pairs), assuming that two pairs constitute one pair.

As described above, the sock collecting and holding device according to the present invention separates the socks taken out from a large number of lasts into two sets and collects them in a bundle on two collecting arms.

After a predetermined number of accumulations have been carried out, the distal ends of the two accumulating arms are made to oppose the distal ends of a pair of latching arms of the holding device, and are temporarily stopped.

The socks are fed from the collecting arm to the pair of latching arms.

When one pair of latching arms is full after a predetermined number of feedings, the holding section on the upper part of the holding device is rotated to move the adjacent pair of empty latching arms to the sock receiving position.

This series of operations is carried out automatically without any manual intervention until all the locking arm pairs are filled. For example, if the sock finishing machine in front of the accumulator is operated in a 2-second cycle, and one set consists of 30 lasts into which socks are inserted, the finishing processing time is 2 (seconds) x 30 (lasts). ) = 60 seconds. Even if this is accumulated in two stages in a secondary accumulation processing device, and the maximum accumulation amount of the accumulation arm, that is, the amount of sending out four times, is accumulated, 60 (seconds) x 2 (stages) x 4 (times) = 480 A worker must remove socks once every second (8 minutes). However, in the accumulating holding device of the present invention, one set of two sets of socks capable of holding socks stacked in two stages and delivered four times is provided in one set of holding arms, and four sets of sets of holding arms are provided. If you use the device, 60 (seconds) x 2 (stages) x 4 (times) x 4 (sets)
=
This means that a worker only has to perform the removal operation once every 1920 seconds (32 minutes). Furthermore, since the accumulating device of the present invention separates and accumulates the socks pulled out from the lasts all at once into two pairs, in the case of 30 lasts, the number of socks to be accumulated per one hanging arm is There are 15 pairs, and of course it is possible to stack 2 tiers to 4 tiers.

(Effects of the Invention) As described above, the sock accumulation and holding device according to the present invention automates the accumulation and holding of a group of socks extracted from a last, and is capable of holding them for many times longer than the conventional method. It is possible to significantly reduce the labor and attention of the person. As a result, it becomes possible to increase the number of machines handled by each person, and it is possible to realize labor-saving and rational processes within a narrow space.

Furthermore, since the stacking operation is performed at two locations using a set of two stacking arms, it can be applied not only to long socks but also to short socks. Furthermore, when two types of socks of different colors and types are divided into groups and inserted into the last of the foot and processed, it is possible to efficiently accumulate and hold them while keeping them separated. It is played.
