Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves feeding textile products such as knitted fabrics in a rope-like bundle, and then processing the fiber products, such as washing, scouring, bleaching, and shrinking, in a processing section on the feeding path. This invention relates to a loop length correction device for a continuous processing machine that continuously performs the following steps.

More specifically, it includes a processing chamber provided in a textile product feeding path, a rotatable squeezing roll provided above the processing chamber, and a rotatable guide roll provided before and after the squeezing roll. In a continuous processing machine, the textile product introduced from one end of the processing chamber is processed while being set in a spiral shape on a squeezing roll and a guide roll and led out from the other end. This invention relates to a device for correcting the loop length of textile products installed in

Various types of continuous processing machines with such a configuration have been proposed. For example, the conventional technology is one that connects textile products (hereinafter referred to as cloth) to form a long piece of cloth and processes this long piece of cloth while feeding it in one direction. It is proposed as.

In addition, a method for processing a long cloth while feeding it back and forth so that the amount of feed in the forward direction is larger than the amount of feed in the backward direction is disclosed in Japanese Patent Application Laid-Open No. 51-47189, which was filed earlier by the applicant.
No. 51-55480.

In such a continuous processing machine, the fabric is transferred as the squeezing roll rotates, but the fabric sandwiched between the squeezing rolls occasionally slips, and the amount of slip at each nip point varies. Since the length of each loop is different due to long-term processing, the length of each loop will fluctuate drastically, resulting in tangles of the fabric in the processing chamber, wrapping of the fabric around the squeezing fluid roll, or cutting of the fabric, resulting in damage to the fabric.
There was a drawback that quality deteriorated and furthermore, it became impossible to operate.

For this reason, it is necessary to correct each loop length before extreme loop length fluctuations occur, but conventional correction work is performed by the operator's visual intuition, so it is impossible to ensure accuracy. In addition, the processing liquid in the processing chamber becomes polluted and foamed due to long-term processing, which makes the process increasingly difficult, resulting in quality deterioration and long-term shutdowns.

Furthermore, since the straightening work involved pulling wet and heavy cloth, it was extremely labor-intensive and the environment was bad.

The present invention was devised in view of the above points, and it is an object of the present invention to provide a device that can correct the loop length simply, easily, and accurately.

The details will be explained below using illustrated embodiments.

Figures 1 and 2 show an example of a continuous processing machine used in the present invention, in which textile products are fed back and forth so that the amount fed in the forward direction is larger than the amount fed in the backward direction. It is of the model type.

Reference numeral 1 denotes a processing chamber storing a processing solution, and storage chambers 3 for storing textile products (hereinafter referred to as cloth) 2 are preferably provided on both sides of the processing chamber 1.
, 3' are provided, and these chambers are supported by frames 4, 4', and the liquid level is adjusted to the same level by making the boundary parts 6, 6' porous.

A squeezing roll 7 is provided above the processing chamber 1, and the upper roll 7' is pressed against the lower roll 7'' by a pressure means (not shown).

The lower roll 7'' is rotated by a drive device 8 capable of forward and reverse rotation via reduction gears 9, 10 and a chain wheel 12 provided on the shaft 11 of the lower roll 7''.

The squeezing liquid roll 7 is set so that the amount of cloth fed by normal rotation (the direction in which the cloth 2 is moved to the left in FIG. 2, ie, the forward direction) is larger than the amount of cloth fed by reverse rotation.

Before and after the squeezing liquid roll 7, there are guide rolls 13, 13 for the cloth 2.
' is provided.

These guide rolls 13, 13' are connected to a chain wheel 1 provided on the shaft 11 of the roll 7'' below the liquid squeezing roll 7.
2, it rotates in the forward and reverse directions together with the squeezing W roll 7, but when the squeezing roll 7 rotates forward (when the cloth moves forward), one side (
The guide roll 13' on the left side in FIG. 2 is actively rotated as a take-up roll, and the other guide roll 1
3 is a clutch 3 operated by a control device (not shown)
0, the transmission from the chain wheel 12 is cut off to create a free state, and the chain wheel 2 rotates passively as the cloth 2 moves.

Also, when the squeezing roll 7 is reversed (when the fabric is retreating), one guide roll 13' is disconnected from the chain wheel 12 by the clutch 30' and becomes free, and the other guide roll 13 is used as a take-up roll. I try to rotate actively.

The reason for configuring the guide rolls 13, 13' in this way is as follows.
When the squeezing fluid roll 7 rotates forward or reverse, the cloth is exposed to the fluid squeezing opening.
This is to prevent the liquid from hanging between the roll 7 and the guide roll 13 or 13' and getting wrapped around the squeezing roll 7, especially the lower roll 7''.

14, 14' are the squeeze roll 7 and the guide rolls 13, 1
Frames supporting 3', 15a to 15h and 16a to
16h is a ring-shaped guide provided between the squeezing roll 7 and guide rolls 13, 13', and 17, 17' are cloths. 18, 18' are delivery rolls, 21a~
21h and 22a to 22h are grid-shaped guides, 24, 2
5, 26, and 27 are guides on the cloth feed side, 28 is a dipping tank, and 29 is a guide on the cloth feed side.

At the time of processing, at least the same amount of cloth is stored in the storage chambers 3 and 3' as the forward rotation of the squeezing roll 7, that is, the forward movement of the cloth 2, and the cloth is stored in the processing chamber 1 in advance. is arranged in a spiral shape on the squeezing roll 7 and the guide rolls 1 3 and 1 3', and in this state, the squeezing roll 7
The treatment is carried out by moving the cloth forward and backward by rotating it forward and backward, and during this period, impregnation and squeezing of the treatment liquid are repeated many times.

This type of continuous processing machine is disclosed in Japanese Patent Application Laid-open No. 51-47189 and Japanese Patent Application Laid-Open No. 51-554, which were filed earlier by the applicant.
No. 80, the present invention aims to easily and accurately correct the loop length of a cloth set in a spiral shape in, for example, such a type of continuous processing machine. Explain details.

In Fig. 3, reference numeral 40 denotes a textile product for straightening (hereinafter referred to as a guiding cloth), and the guiding cloth 40 has two detectable pieces separated by a predetermined interval L (an interval corresponding to the specified loop length). A portion 41.41' is provided.

The detectable portions 41 and 41' can be made of metal foil, metal thread, fluorescent dyed thread, metal mesh, etc., but in the embodiment, aluminum foil is arranged over the entire width of the guide cloth 40, the cloth is placed on top of the aluminum foil, and the sewing machine is used to sew. I'm using something like that.

The guide cloth 40 is connected to guides 42, 43, 44-, 45, 46 provided above the processing chamber 1 as shown in the developed view of FIG.
When correcting the loop length, it is connected to the ends of the treated cloth 2 cut off at the introduction side and the outlet side of the treatment chamber 1 to form an endless loop.

47a to 47h are detection devices for detecting the detectable portion 41.41' provided on the guide cloth 40, and as shown in FIG. In this case, the same number of nips (8 in the illustrated example) as the nip portions of the treated cloth 2 in the 7 parts of the squeezing liquid rolls are provided near the guide roll 13'.

The detection devices 47a to 47h are set at substantially the same intervals as the intervals between the treated cloths 2 hanging from the guide roll 13'.

In FIG. 5, 48 is a mounting member for the detection devices 47a to 47h.

The detection devices 47a to 47h are detectable portions 41
, 4 If 1' is metal foil, use an edge current type proximity switch; if it is metal thread or metal mesh, use iron piece detection type;
In the case of fluorescent dyed yarn, a fluorescent detection type is used.
The embodiment uses a proximity switch, which shuts down the machine when the detection device is activated.

In FIG. 4, 55 and 56 indicate that the detectable portion 41 is connected to the detecting devices 47a to 47 during loop length correction.
This is a stopping device (details will be described later) for stopping the running of the cloth in the corresponding portion when detection is made of the cloth in the processing cloth 2.
above).

Examples of the stop devices 55, 56 are shown in FIGS. 6 to 8 (FIGS. 7 and 8 show only one stop device 55, and FIG. 8 is a view seen from the direction of arrow B in FIG. 7). As shown in
Two hooks 55', 55" and 56', 56 set at intervals wider than the diameters of the guide rolls 13, 13'
When correcting the loop length, the hook is rotated by a rotating means (described later) to hook the corresponding portion of the cloth 2 and separate the cloth from the guide rolls 13, 13' (see Figs. 7 and 8). (see) to stop the running of the corresponding dissecting cloth.

The stopping devices 55 and 56 are connected to the truck 6 as shown in FIG.
The universal joint 58 passes through the bearings 57, 57' attached to the
, 58' and shafts 60, 60' connected via a shaft 59 on a truck 62, and are rotated integrally by rotating a handle 61 attached to one of the shafts 60.

The trolley 62 is mounted on rails 63 and 63' installed above the processing chamber 1 (the rails use stays provided at the top of the machine base in the embodiment) via pulleys 64 and 64'. The stop device is moved in the axial direction of the squeezing roll 7 as the carriage 62 moves (the moving positions are shown in FIG. 4 as 55a to 55g and 56a to 56g).

The fixed shafts 60, 60' of the stopping devices 55, 56 control the contact start point and release point of the cloth 2 at the guide rolls 1 3, 1 3' when the upper roll 7' of the squeezing roll 7 is lifted. It is placed almost parallel to the connecting line.

Note that the shape and number of hooks used as the stopping devices 55 and 56 are not limited to those shown in the drawings.
It can be selected as appropriate, and although the hook is manually rotated in the illustrated example, it can also be automatically rotated by a motor or the like.

Further, although the illustrated example shows a hook that is rotated, the hook may be fixed to the trolley 62 and the cloth may be hooked by hand.

Furthermore, instead of the hook, a grip-type stopping device may be used to separate the cloth from the guide rolls 13, 13', and the grip may be connected to the cloth feeding path, for example between the squeezing fluid roll 7 and the guide roll. If it is provided between 13 and 13' to grip and hold the cloth, the guide roll 13,
The running of the cloth can be stopped without separating the cloth from 13'.

Furthermore, although the carriage 62 and therefore the stop devices 55 and 56 are moved manually in the embodiment, they can also be moved automatically.

Further, although the stopping devices 55 and 56 are moved by a trolley 62 in the illustrated example, other means may also be adopted.

When correcting the loop length, the machine is stopped in advance, the treated cloth 2 is cut off at the introduction side and the outlet side of the treatment chamber 1, and the ends of the separated treated cloth 2 and the detectable portion 41 are separated.
．． 41' are connected to form an endless guide cloth 40, and the squeezing cloth 7' above the liquid squeezing roll 7 is lifted up (see FIG. 6).
are located at 55a, 55a.

Here, the loop length after processing (in the example, the length of the cloth leading to the adjacent detection device) is 25 m from the inlet side, 4 m.
Assume that the distances are 5 m, 25 m, 25 m, 45 m, 25 m, and 25 m, and that the interval L between the detectable portions 41.41' is 35 m, that is, the specified loop length is 35 m.

In this state, the guide roll 1 on the receiving side
3', that is, in the forward direction, and after the head portion 41 of the detectable portion passes the detecting device 47a during the traveling, the detecting devices 47a to 47h are enabled to operate.

The cloth continues to run in this state, but since the first loop length is shorter than the specified length, the head 4 of the detectable part
1 reaches the detection device 47b before the butt 41', and in response to the detection by the detection device 47b, the machine is stopped, and therefore the running of the cloth is stopped.

At this time, the stop devices 55 and 56 are operated as shown in FIGS.
Pull away from 13'.

The machine is then driven by pressing a machine start switch (not shown), so that the fabric is moved again to the guide roll 13.
', but the cloth hooked to the stop devices 55 and 56 remains in a stopped state.

Next, when the detectable portion 41' reaches the detecting device 47a and is detected, the machine is stopped again, and therefore the running of the cloth is stopped.

This means that the first loop length correction has been completed.

After the correction is completed, the stop devices 55 and 56 are operated in the opposite direction to the above to leave the cloth in its original state (to be placed on the guide roll 1313'), and the stop devices 5556 are moved (55 is set to 55b, 56 is set to 56b).

Next, the machine is driven again to correct the second loop length, but since the second loop length is longer than the specified length, in this case, the butt 41' is detected by the detection device 47b before the head 41. reached,
In response to the detection by the detection device, the machine is stopped and therefore the running of the cloth is stopped.

In this case, the machine is driven again without operating the stop devices 55 and 56, so that the cloth runs, and the head 41 is detected by the detection device 4.
7c and the machine is stopped and therefore the running of the cloth is stopped, the stop device 5556 is actuated to separate this portion of the cloth from the guide roll 1313' and keep this portion of the cloth in a stopped state.

Next, the machine is driven in the opposite direction (backward direction) to the above (in this case, the guide roll 13 is on the active rotation side, and the cloth is run by this guide roll 13), and the butt part 41'
When it reaches the detection device 47b, the machine is stopped in response to the detection by the detection device, and accordingly, the running of the cloth is stopped.

This completes the correction of the second loop length, and after the correction is completed, the stop devices 55, 56 are operated in the opposite direction to return the fabric to its original state.

Thereafter, the loop lengths are corrected sequentially in the same manner, and after the entire loop length has been corrected, the machine is stopped and the guide rolls 1 3 .
13' is stopped, the detection devices 47a to 47h are made inactive, and the squeezing roll 7 is also returned to its original state.

When processing is to be performed again, the connection between the treated cloth 2 and the guide cloth 40 is separated, and the treated cloth 2 is separated from the ends of the treated cloth 2 in the treatment chamber 1 and the treated cloth is separated and stands by on the introduction side and outlet side of the treatment chamber 1. 2
In this state, the machine is driven again to perform processing.

In addition, in the embodiment, the loop length correction is performed when moving the endless cloth in the forward direction, but the correction may be performed when moving the endless cloth in the backward direction.

In addition, in the embodiment, two detectable portions are provided, but three or more may be provided, and in this way, the loop length before or after the loop length correction portion, or before and after the loop length correction portion, is set to the specified length. It becomes possible to judge whether the length is longer or shorter than the length.

Furthermore, although the illustrated example shows an example in which the present invention is applied to a reciprocating feeding type continuous processing machine, it can also be applied to a unidirectional feeding type continuous processing machine.

Since the present invention is as described above, it is a truly effective invention as it allows loop length correction to be performed simply, easily, accurately, and in a short time without requiring any effort.
