Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for pulling a vertically elongated woven fabric such as women's stockings or socks on a mold arranged in a half-mold machine. The machine of the invention is in addition to all semi-molded machines of the appropriate mold.

[0002]

2. Description of the Prior Art In the past, an operator had to stand on a ramp and pull up the stockings over the pair of dies in a half-machine with an extended stance.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to automate all the operations of a machine so that the work of the operator can be done easily, the work efficiency and speed are increased, and the burden on the operator is greatly reduced. The purpose of the present invention is to provide a lifting device. The machine of the present invention allows stockings to be placed on the mold in a more uniform manner and cycle than in the previous manual operation.

[0004]

In order to achieve the above object, a lifting device of the present invention comprises a stocking, tights,
An elongate fabric lifting device, such as a sock, comprises a fixed transfer station connected to two transfer hooks, said hooks being mounted around their own axis.
Pivoting over an angle of more than 80 °, transferring the tights to two pull hooks connected to the circulating chain, which pull hooks then use a synchronous roller placed on both sides of the mold to remove the mechanism onto the mold. With flaps to pull up the fabric, frequency converter controlled motor for hooking and transfer station, and opto-electrical switch, which recognizes whether stocking is hooked or not and is freely programmable It is characterized in that it is integrated in the control device.

The lifting station is a separate part of the uniform machine. Homogeneous machines are half-machines for inspecting and smoothing stockings and the like before these fabrics are delivered to the packaging machine. Since the worker only attaches the stockings or the fabric to the hooks of the transfer station, the device for lifting the vertically elongated fabric greatly reduces the burden on the worker. This greatly reduces the burden on the operator as the work can be done completely in the sitting position.

EXAMPLE A worker stands in front of a transfer station (3) and moves a stocking (2) with a waist elastic onto a transfer hook (4) towards the machine (1) (FIG. 1). The opto-electrical switch (5) recognizes that the stocking is ready and activates the lifting section (7). The transfer hook (9), or in the case of socks, the transfer station (3) is activated when the lift hook (9) and the hook (9a) reach a certain position.

If the transfer hook (4), or in the case of a sock, the transfer hook (4) and the hook (4a) are moved to a limit position in the direction of maximum movement of slightly more than 180 °, the result is two pulls. The hooks (9) and (9a) have enough space to transfer the fabric (2) vertically upwards (FIG. 9). The transfer hooks (4) are connected by a curved section (16). On this curved section (16) there are two curved roller tracks (17) which ensure that the transfer hooks (4) carrying the stockings (2) extend in the forward direction towards the lifting hooks (9). To do. To raise the socks, the machine (1) works with an additional fixed transfer hook (4a).

On the left side of the mount for the transfer station (3) is a contact (13), which is the sensor (1
4), thus controlling the motor (12) for the transfer station (3) and returning the transfer hook (4) and the additional hooks (4a) used for the socks to their initial position (FIG. 6). ). To the right of the mounting for the transfer station (3) is a contact (15), which is
When the two sensors (16) are started, the motor (12) for the transfer station (3) is stopped and it is checked whether the transfer station (3) is in its initial position and thus the next cycle can be started. (Fig. 6).

The transfer operation for the oblong shaped textiles from the transfer station (3) to the pulling station (7) is carried out in a continuous process (FIG. 9). Photoelectric switch (5)
Starts the motor (6) of the lifting section (7) on the lifting station (1) and thus the lifting hook (9) rigidly connected by the two chains (8).
To start. The circulating chain (8) has two pairs of lifting hooks (9), which are arranged opposite one another in the chain (8).

A protrusion (11) on the left chain (8)
The contacts (10) are triggered during the circulation of the chain (8) in such a way that (FIG. 4) first triggers the contacts (10) by the movement of the chain (8). The transfer hook (9) is then activated. At the point where both the transfer hook (4) and the pull-up hook (9) meet, the stocking (2) or other fabric is transferred (Fig. 9).

The protrusion (18) horizontally connected on the right chain (8) of the lifting station (7) passes the sensor (19) placed on the right side, and then the lifting hook (9) is brought into a fixed position. Stop. Another sensor (20) can check whether the lifting station (7) is in its initial position and start the subsequent cycle (Fig. 4).

Engagement (3) and lifting station (7)
The motor for is controlled by a frequency converter (38). In the lifting station (7) the stockings are at the highest point of the circulation chain (8) (Fig. 8).

Transfer from this position to the mold (21) takes place. This is done by the light barrier (22) and the sensor (23). The sensor brings parallel pulling rollers (24) together. These rollers are movably mounted (25).

The motor (27) is mounted on the respective roller (24) or holding plate (26). The holding plate causes a rotational movement of the roller. The sensor (23) and the light barrier (22) act on both the motor (27) and the pneumatic system (28) attached to them. The pneumatic system (28) moves the lifting roller (24) from both sides towards the vertical mold (21) (FIG. 8).

This movement is carried out synchronously from both sides, the pull-up roller (24) is rotated by the above-mentioned contacts (22 and 23) and the stocking (2) on the mold (21) is pressed by the roller (24). By means of being pulled along the mold (21). This releases the lifting hook (9) on the lifting station (7). These rollers (24)
Without it, the stockings (2) will tear prematurely as a result of excessive pulling forces. The period during which the roller (24) moves is controlled by the time generator (38) (Fig. 1).
This period depends on the length of the stockings (2) and is therefore variable (Fig. 8).

At the highest point (FIG. 8) at the lifting station (7) is a specially shaped flap (29), which is designed to stop the two legs of the stocking from slipping. Without this flap (29), the two legs of the stocking fall uncontrollably onto the mold (21) or onto a part of the machine, resulting in damage to the stocking.

The aforementioned light barrier (22) placed behind the lifting station (7) raises the flap (29) by means of the cylinder (30) when it recognizes that the stocking (2) is in place. When the motor (6) for the lifting station (7) is stopped, the flap (29) returns to its initial position (Fig. 8). A removal mechanism (31) is provided in the pull-up hook (9) to release the stocking (2) on the mold at the proper position (Fig. 10).
12).

Near the center of the lifting station (7) (FIG. 9) is a horizontally mounted shaft (32) on which two sprockets (33) are fixed;
They are connected by two circulating chains (34), while these chains are arranged axially. These two chains (34) have a plastic cover (35) which triggers the removal action of the lifting hook (9) removal mechanism.

Two release levers (31) (FIGS. 10-10)
13) are cam rubbers (36) on their bent portions, respectively.
Attached, which holds the stockings (2) in place as described above. These two rubbers are provided in a lever mechanism (31) which uses a tension spring (37) with a plastic bend (35) attached to the circulation chain (34) in the position (21) above.
Remove the upper stockings (2) and thus release (Figs. 10-12). The entire operation of the inventive lifting machine (1) and the interconnecting parts is controlled by a freely programmable controller (38).

Next, the stocking is a half-type machine type (2
1) Fully pulled up. The mold itself constitutes an independent part of the machine. In the next cycle, the semi-die machine raises the following die (21) in front of the machine (1),
The above process is carried out in which the stockings on the transfer station (3) are placed on the lifting hooks (9) of the lifting part (7) using the transfer hooks (4). The present invention is not limited to the above description, and various modifications can be made within the scope of the present invention.
