  The present invention relates to a calendar type roll finishing machine having a plurality of main rolls, and a method of using the same.

FIG. 2 shows a conventional example of a calendar type roll finishing machine.
Three main rolls are arranged parallel to each other. That is, the first-stage main roll 1, the second-stage main roll 2, and the third-stage main roll 3 are respectively disposed horizontally.
Each main roll has a heat belt. That is, the first-stage heat belt 6 for the first-stage main roll 1, the second-stage heat belt 7 for the second-stage main roll 2, and the third-stage heat belt for the third-stage main roll 3. 8 are respectively wound.

Each of the three main rolls is heated by supplying steam, and the first-stage main roll 1 is driven to rotate counterclockwise (counterclockwise) as indicated by an arrow L. The third-stage main roll 3 is driven to rotate clockwise (clockwise) as indicated by an arrow R.
A plurality of compression rolls 4, 4 ′, 4 ″ are arranged above the first-stage main roll 1, and are rotated clockwise as indicated by an arrow r by friction transmission from the first-stage main roll 1 (clockwise). Direction).

The laundry (washed, dehydrated, and so on) is fed by the infeed conveyor 5 as indicated by the arrow a.
It is fed between the first-stage main roll 1 and the compression roll 4 and proceeds as shown by the arrow b while being sequentially compressed by a plurality of compression rolls, and then the first-stage main roll 1 and the first-stage heat. It is sandwiched between the belt 6 and proceeds as indicated by an arrow c and pressed.
Further, the sheet is pressed between the main roll and the heat belt while proceeding as indicated by arrows d, e, f, and g, and discharged as indicated by arrow h.

Reference numeral 9 denotes a guide tape which is wound around the compression rolls 4, 4 ′, 4 ″ and travels between the compression roll and the first-stage main roll 1. .
The heat belt is a member for sandwiching and pressing the laundry with the main roll, and therefore requires a suitable strength, for example, a thickness dimension of 1-2 mm and a width dimension of 100-200 mm.
Compared to this, the guide tape 9 is a member for preventing the wrapping of the laundry, and does not require an extra strength. The thickness dimension is 0.1-0.2 mm, the width dimension is 15-30 mm, and it is a completely different component from the heat belt.

FIG. 4 is a view for explaining a problem in the conventional roll finishing machine. Of the four compression rolls depicted in FIG. 2 described above, at the end near the feeding conveyor 5. The pressure roll 4 located, the pressure roll 4 'located next to it, and the vicinity thereof are extracted and drawn.
What is shown with the code | symbol 11 is the trousers as an example of a to-be-processed object. For example, when the pants are sick clothes, the folded portion 11a at the hem has a maximum thickness of 40 mm and has a step.

The first-stage main roll 1 is rotated in the direction of arrow L, and the compression roll 4 is in contact with the first-stage main roll 1 and is driven to rotate in the direction of arrow r. In this state, when the folded part 11a of the trousers is inserted, the pressure roll 4 is lifted due to the level difference of the folded part.
When lifted, the rotation of the compression roll 4 often stops.
When a subsequent workpiece is sent to the place where the rotation of the compression roll 4 is stopped, a trouble of “clogging” occurs.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its purpose is to provide a roll finishing machine and a roll that do not clog the workpiece even when the thickness of the workpiece is not constant and there are steps. It is to provide a finishing method.

The basic principle of the present invention created to achieve the above object will be described with reference to FIG. 4 described above.
The reason why the workpiece (trousers 11 in this example) does not advance is because the compression roll 4 stops, but not because the compression roll 4 is lifted.
When a thick part of the workpiece is approached, the trouser 11 is advanced if the compression roll 4 continues to rotate even if the compression roll 4 is lifted.
From this consideration, the present invention forcibly drives the rotation of the compression roll 4 so as not to stop.

The present invention will be described with reference to FIG. 1 corresponding to one embodiment thereof. In the description of this paragraph, reference numerals are added for easy comparison with the drawings, but the reference numerals do not limit the configuration of the present invention.
Reference numeral 6 indicates a first-stage heat belt (drawn with imaginary lines) in the conventional example. In the invention of claim 1, the heat belt is extended and wound around the compression roll 4 as indicated by a solid line and a reference numeral 12.
As a result, the extended first-stage heat belt 12 also serves as a belt transmission and forcibly drives the compression roll 4 to rotate.
As described above, the principle of the present invention is to forcibly drive the compression roll 4. Accordingly, the driving means is not necessarily limited to the heat belt. Although not shown, the above-mentioned purpose (prevention of clogging due to stoppage of the compression roll) can be achieved even if a dedicated drive means (for example, a direct-coupled motor or a chain / sprocket pair) is provided on the compression roll 4.
Hereinafter, each claim will be specifically described.

Also, the rotation of the compression roll continues without stopping. For this reason, the level difference portion of the object to be processed is sandwiched between the first-stage main roll and the compression roll and sent without any delay, and the subsequent object to be processed is not clogged.

  When the method of the invention of claim 3 is applied, even if the thickness of the workpiece is indefinite and has a step, the pressing roll is forcibly rotated by frictional transmission by the heat belt. Even when applied, the rotation of the compression roll continues without stopping. For this reason, the level difference portion of the object to be processed is sandwiched between the first-stage main roll and the compression roll and sent without any delay, and the subsequent object to be processed is not clogged.

  When the method of the invention is applied, even if the thickness of the object to be processed is indefinite and has a step, the pressing roll is forcibly rotated by the dedicated driving means, so that the stepped portion has come into contact with the pressing roll. Sometimes, the rotation of the compression roll continues without stopping. For this reason, the level difference portion of the object to be processed is sandwiched between the first-stage main roll and the compression roll and sent without any delay, and the subsequent object to be processed is not clogged.

FIG. 1 is a schematic sectional view showing an embodiment of the apparatus of the present invention.
In the conventional example shown in FIG. 2 described above, the first-stage heat belt 6 is wound around the first-stage main roll 1 about the lower left half of the figure.
In FIG. 1 (this embodiment), the first-stage heat belt 6 of the conventional example is appended with a virtual line for comparison.
Reference numeral 13 denotes a guide roll that guides the extended first stage heat belt 12.

In this embodiment, a heat belt is extended compared with a prior art example, and it winds around the compression roll 4 like the 1st step | paragraph heat belt 12 drawn with the continuous line.
The guide tape 9 wound around the compression rolls 4, 4 ′, 4 ″ in the conventional example (FIG. 2) is omitted. The reason is as follows.
The role of the guide tape 9 in the conventional example is to prevent the object to be processed from being wound around the compression roll. For this reason, the guide tape 9 is a member having only a strength sufficient to prevent winding.
Since the heat belt is wound around the compression roll by applying the present invention, the object to be processed is prevented from being wound. For this reason, the guide tape 9 is not necessarily required.

The first-stage main roll 1 is driven to roll in the direction of arrow L by a drive mechanism (not shown).
Since the first-stage heat belt 12 is in contact with the first-stage main roll 1 over a wide area, the first-stage heat belt 12 is strongly circulated by frictional transmission.
The compression roll 4 is strongly driven to rotate in the direction of arrow r by the extended first-stage heat belt 12.
Since it is driven to rotate strongly as described above, even if the thickness of the workpiece fed between the compression roll 4 and the first-stage main roll 1 is not constant and there is a step, the compression roll Does not stop rotating. For this reason, the progress of the workpiece is continued without stopping, and there is no possibility of clogging the subsequent workpiece.

As can be understood from the principle of operation and effect in the embodiment described with reference to FIG. 1, the direct reason why this embodiment can achieve the intended purpose is to force the compression roll 4 to rotate. Because.
Therefore, even if the heat belt is not necessarily extended and wound around the compression roll 4, the object of the present invention is achieved by providing a dedicated rotation driving means for the compression roll.
In this case, the type of the rotational drive means is not limited, and for example, a direct motor may be provided, a chain / sprocket may be provided, or a gear transmission mechanism may be provided.
