Description

[Detailed Description of the Invention] The present invention relates to a sock supply device, and more specifically, it supplies long socks such as seamless stockings or pantyhose to a predetermined position on the sock placement surface of an automatic sock folding and packaging machine. This invention relates to an automatic sock feeding device that is designed to accurately feed socks.

Conventionally, several automatic folding and packaging machines for socks have been proposed and put into practical use.

Patent application No. 117585, filed by the applicant earlier
The device disclosed in No. 1 is one such device, and this device is designed so that the central leg of the sock is positioned on a transfer member disposed approximately in the center of the sock placement surface on the machine table. The sock is manually supplied to the sock placement surface in a stretched state, and a sheet of mount is superimposed and placed on the central leg of the supplied sock, and then the mount is temporarily placed. While gripping the sock, the waist part and the tip of the leg are simultaneously folded in half from the left and right sides using a pair of folding bars.
The folded socks are folded onto the mount along both side edges of the mount, and then the folded socks are transferred by the transfer member to a position on the line of the packaging bag that has been kept waiting in advance, and the transferred folded socks are transferred to the insertion member. The socks are packaged by being clamped and inserted into the waiting packaging bag, and the folding and packaging operation of the socks is carried out with high efficiency.

However, the above-mentioned automatic folding and packaging machine for socks requires an operator to manually feed one pair of socks in a stretched state and at an accurate position on the sock placement surface of the machine, and therefore, the sock feeding operation is difficult. This takes time, and the next sock cannot be fed onto the sock placement surface until the previous sock folding process is completely completed. This results in inefficient socks supply work.

Furthermore, since the sock folding operation is performed by moving a pair of folding bars from side to side on the sock placement surface, the sock supplying operation is dangerous for the operator.

The purpose of the present invention is to provide a device which solves the above-mentioned conventional problems and can extremely safely and efficiently feed socks onto the sock placement surface of an automatic sock folding and packaging machine. It is something to do.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

A sock transfer member 3 that transfers from the lower placement surface 2a to a position on the line of the packaging bag that is placed on standby in advance, a mount supply member 4 that supplies a mount for one sheet to a predetermined position of the sock transfer member 3, and the sock placement member 4. A sock folding member 5 having a pair of folding bars 5a and 5b for simultaneously folding the waist portion and leg tip portions of a sock placed on the surface 2a in a stretched state in half from the left and right directions and folding the sock onto the mount. and a sock inserting member 6 that receives the folded socks from the sock transfer member 3 and inserts the socks into a packaging bag that has been kept waiting in advance, and these members are arranged alternately or overlappingly. By functioning functionally, the folding and packaging operation of socks is carried out automatically and continuously.

For the configuration and operation of the above-mentioned transfer member 3, mount supply member 4, folding member 5, and insertion member 6, please refer to the specification and drawings of Japanese Patent Application No. 11758/1983 filed by the applicant of the present application. I want to be

Therefore, the structure of a sock supplying device for automatically supplying socks onto the sock placement surface 2a of the table 2, which is the object of the present invention, will be described below.

As shown in FIGS. 1 to 4, in the front vertical frame of the machine base 1, a pair of bearing brackets 1 are provided at both left and right ends.
2.13, and gears 15, 16 and 17 are respectively fixed to a horizontal rotation shaft 14 rotatably pivoted between the bearing brackets 12 and 13, and the gear 15 has a driving gear 18.
The gear 16 has a concave bracket (19) fixed to both ends of the upper surface of the left bearing bracket 12.
．． The left rack member 21, which is slidably disposed in a direction orthogonal to the rotating shaft 14, is fitted into the recess of the right bearing bracket 13, and similarly, the gear 17 is fitted into the recess of the right bearing bracket 13. concave brackets fixed to both ends of the top surface)
The right rack member 24 slidably fitted into the recessed portions 22 and 23 is engaged with each other, and a sock supply plate 25 is attached between these left and right rack members 21 and 24.
5 can be moved back and forth with the reciprocating sliding movement of the rack members 21, 24.

Also, on the rear side of this supply plate 25 is a work table 11 on which a large number of socks P (FIG. 1) to be placed on the supply plate 25 are stacked.
has been set up.

A one-rotation intermittent motor 26 is disposed on the left side frame of the machine base 1, a disk 27 is fixed to the rotating shaft of the motor 26, and one end of the outer periphery of the disk 27 is integrated with the drive gear 18. A connecting rod 29 is connected between the tip of the arm 28 and the drive gear 1 is driven by one rotation of the motor 26.
8 in the forward and reverse directions.

That is, as shown in FIG. 4, when the motor 26 is driven for one rotation, the disk 27 is first rotated by half a rotation in the direction of the arrow a in the first half rotation. The arm 28 is swung from the solid line position to the chain line position, and then, by the remaining half rotation of the motor 26, the arm 28 is swung back from the chain line position to the solid line position in the opposite manner.

In this way, the arm 28 is oscillated in a clockwise manner by one rotation of the motor 26, so that the drive gear 18
is rotated forward and backward by a certain angle, and the first forward rotation of the drive gear 18 (clockwise rotation in FIG. 4) causes the gear 15 meshing with the drive gear 18 to rotate counterclockwise together with the rotation shaft 14. As a result, the gear 16 fixed to the rotating shaft 14.
The rack members 21 and 24 engaged with the drive gear 17 slide forward to advance the supply plate 25 from the front position of the machine base 1 to a predetermined position on the sock placement surface 2a of the table 2, and then the drive gear 18 The advanced supply plate 25 is returned to its original position together with the rack members 21 and 24 by the reverse rotation.

Therefore, if one pair of socks P is placed on the supply plate 25 in a stretched state, the sock will be transferred to a predetermined position on the sock placement surface 2a of the table 2 as the supply plate 25 moves forward. Become.

As shown in FIG. 1 and FIGS. 2 and 3, on the sock placement surface 2a of the table 2 are socks P that have been transferred to a predetermined position on the sock placement surface 2a by the advancement of the sock supply plate 25.
A sock presser 33,34 that holds the sock in a stretched state by temporarily pressing both left and right ends of the sock against the upper surfaces of left and right holding stands 31,32 disposed on the sock mounting surface 2a. It is set up.

That is, a pair of Z-shaped brackets t-35 and 36 are fixed to both left and right ends of the sock mounting surface 2a, and pneumatic cylinders 37 and 38 are fixed perpendicularly to the upper surfaces of each of the Z-shaped brackets 35 and 36. The pressers 33 and 34 are attached to the piston rods 37a and 38a.

When the pneumatic cylinders 37, 38 are actuated and their piston rods 37a, 38a move forward, the pressers 33, 34
Both end portions of the sock P that has been lowered and placed on the supply plate 25 are cut into long grooves 25 a and 25 b in the supply plate 25 .
The sock is temporarily held in a stretched state by being pressed against the upper surface of a holding base 31, 32 (see FIG. 1).

Thereafter, by returning the supply plate 25 to its original position in the above state, only the held socks remain in that position, and then by releasing the holding of the socks by the pressers 33 and 34. The socks fall in an orderly manner and are accurately supplied to a predetermined position on the sock placement surface 2a.

The sock supply device according to the present invention has the above structure, and its operation will be explained next.

The worker picks up the highest pair of socks P that are stacked on the workbench 11 and places them on the supply plate 25 in a stretched state at a predetermined position, and then presses a start switch (not shown). By pressing , the supply plate 25 moves forward from the front position of the machine base 1 during the first half rotation of the motor 26, and the socks P placed on the supply plate 25 are removed together with the supply plate. The socks are transferred to a predetermined position on the sock placement surface 2a.

Immediately before this transfer, for example 0.1 to 0.2 seconds, the pneumatic cylinders 37.38 are actuated to advance the piston rods 37a and 38a, thereby lowering the presser 33.34. Socks P transferred to a predetermined position
Both ends of the holding table 31.32 are held by the holding tools 33.34.
Press down to temporarily hold the sock in a stretched state.

The motor 26 continues to be rotationally driven, and therefore, after the supply plate 25 is returned from its forward position to its original position in front of the machine during the remaining half rotation, the motor 26 returns to its first position.
Completes rotational drive and stops.

Immediately after the supply plate 25 is returned to its original position, the pneumatic cylinder 37.38 is deactivated and the presser 33.34
By raising the sock P and releasing the hold on the sock P,
As shown in FIG. 5, the socks P fall neatly from the positions on the holding bases 31 and 32 onto the sock placement surface 2a.
It is supplied in a stretched state to a predetermined position on a.

The socks P supplied onto the sock placement surface 2a are folded and packaged by the automatic sock folding and packaging machine described above.

As described above, the present invention includes a sock supply plate that reciprocates between a position in front of the machine stand and a predetermined position on the sock placement surface, and a sock that temporarily holds the socks transferred by the supply plate. By providing a presser for releasing the holding of the socks and supplying the socks onto the sock placement surface after the supply plate retreats and returns, the operator can simply place the socks in a stack on the workbench. All that is required is to pick up the topmost pair of socks and place them on the supply plate in a stretched state at a predetermined position, and the subsequent operation of supplying socks onto the sock placement surface is all done automatically. This allows the worker to safely and easily place socks on the supply plate, and also allows the worker to place the next sock on the supply plate even when folding socks in the automatic sock folding packaging machine. This has the effect of allowing socks to be supplied at a fractional rate.
