Description

  The present invention relates to a roll finishing machine that automatically and continuously press-finishes an object to be washed after being washed in a continuous washing machine and then dehydrated by a dehydrator.

2. Description of the Related Art Conventionally, in a continuous laundry facility, a roll finishing machine has been used as an apparatus for continuously press-finishing washed and dehydrated items. This roll finisher transports the article to be washed in close contact with the surface of the main roll while passing between the heated main rolls that rotate and the compression roll that rotates in close contact with the main roll. By doing so, the wrinkles of the article to be washed are stretched and roll-pressed. (See Patent Document 1).
In this roll finishing machine, a chain drive means comprising a roller chain and a drive sprocket with teeth meshing with the roller chain is usually used as a rotation drive device for the main roll. The characteristics of this chain drive means are that it has high strength and high torque, and that the chain is less stretched. This ensures that the rotation of the motor, which is the rotation drive source, can be rotated multiple times using the chain and sprocket. Is transmitted to the main roll.

JP 2008-183101A

  However, the conventional chain driving means described above requires lubrication oil because the metal of the chain and the sprocket are engaged and rubbed with each other. In addition to the occurrence of contamination due to the scattering of the oil, the metals contact each other. Therefore, it has been desired to improve the working environment. In addition, the generation of noise is caused by the engagement between the chain and the sprocket, and as the speed of the chain increases, the noise increases and becomes annoying. It was difficult to increase the rotation speed of the roll (the outer peripheral speed of the main roll was about 50 m / min at the maximum).

  The present invention has been made in view of such circumstances, and does not require lubricating oil, does not cause dirt due to oil, and has a low noise level associated with the rotational drive of the main roll, thereby reducing the rotational speed of the main roll. It is an object of the present invention to provide a roll finishing machine capable of increasing the number of rolls.

  As a result of diligent research in view of the above problems, the inventor has developed a roll finish that enables belt drive means comprising a V belt and a V pulley to be used instead of chain drive means comprising a roller chain and a drive sprocket. I came up with the opportunity.

  That is, the device of the present invention provides a roll finishing machine that is driven using a V-belt instead of the chain driving means used in the conventional roll finishing machine.

  As described above, the roll finishing machine of the present invention is a roll finishing machine that presses and presses an object to be washed against a plurality of main rolls, and a V belt and a V pulley are used as connecting members for rotationally driving the plurality of main rolls. And a motor for driving the V-belt so that the rotation speed of the main roll on the downstream side of the conveyance path of the washing object is always higher than the rotation speed of the main roll on the upstream side. It is arranged on the main roll on the downstream side of the path.

  The roll finishing machine of the present invention is characterized in that a reduction gear for reducing the rotation of the motor is disposed between the motor and the main roll.

  The roll finishing machine of the present invention is characterized in that a reduction gear is arranged on the rotation shaft of each main roll, a V pulley is arranged on the reduction gear, and the V pulley is connected by a V belt. And

  In the roll finishing machine of the present invention, the diameter of the downstream V pulley is increased to increase the rotation speed of the main roll on the downstream side of the conveyance path of the washing object to be higher than the rotation speed of the upstream main roll. It is characterized in that it is set smaller than the diameter.

  The roll finishing machine of the present invention is characterized in that a reversing mechanism for reversing the rotation direction of adjacent main rolls in a plurality of main rolls is interposed between adjacent main rolls.

  In the roll finishing machine of the present invention, the reversing mechanism includes two toothed pulleys and both toothed belts having convex teeth on the front and back to connect the two toothed pulleys. It has an engaging part engaged with the front and back teeth of this.

  In the roll finishing machine of the present invention, the reversing mechanism has an idler pulley interposed between two toothed pulleys connected by both toothed belts, so that the front and back surfaces of both toothed belts are respectively placed on the two toothed pulleys. The teeth are engaged.

  As described above, according to the roll finishing machine of the present invention, the use of the V-belt eliminates the need for lubricating oil, does not cause dirt due to oil, and the noise level associated with the rotation driving of the main roll is low. At the same time, the main roll can be rotated at a higher speed than the chain driving means, and thereby the work efficiency can be improved while realizing a good working environment in the roll finishing.

It is a schematic explanatory drawing of the roll finishing machine which concerns on this invention. It is a partial expansion perspective view which shows the both-tooth belt used for the roll finishing machine which concerns on this invention. The toothed pulley used for the roll finishing machine which concerns on this invention is shown, (a) is a perspective view, (b) is a side view.

  Hereinafter, an embodiment for carrying out a roll finishing machine of the present invention will be described in detail with reference to the accompanying drawings. 1 to 3 are diagrams illustrating embodiments of the present invention. In these drawings, the same reference numerals denote the same components, and the basic configuration and operation are the same. To do.

FIG. 1 shows a roll finishing machine 1 according to the present invention. This roll finishing machine 1 takes in a wash or dehydrated cloth, etc. sent from a continuous washing machine or dehydrator (not shown). It is a calendar type roll finishing machine that is responsible for one step of a continuous washing facility that automatically roll presses, and that includes a plurality of main rolls, four in this embodiment. In FIG. 1, the main roll, its drive system, and the conveyance path are shown in an easy-to-understand manner, and the compression roll, tension pulley, support structure, and the like are omitted.
And, in order to secure a sufficient length for the article to be washed to be in close contact with the main roll while making the roll finisher 1 small and space-saving, the main roll is not simply arranged in a row horizontally, It is arranged so as to be shifted in the vertical direction, and the object to be cleaned is conveyed in a zigzag manner in the apparatus.

  The V-belt used in the present invention is made of a composite material composed of rubber and other elastomers and fibers having a V-shaped longitudinal section (strictly, trapezoidal), and the V pulley engaged with this is at the same angle as the V belt. It has a V-shaped groove in cross section. A strong frictional force is generated when the V-belt bites into the groove of the V-pulley like a wedge, whereby a relatively large power can be transmitted with a thin belt.

  The operation of the roll finishing machine 1 will be described. As shown in FIG. 1, the object to be washed introduced from the inlet 2 is wound around the outer periphery of the first main roll 3 that is arranged at the upper right of the inlet 2 and rotates in the clockwise direction. Next, it is wound around the second main roll 4 that is arranged at the lower left and rotates counterclockwise, and then wound around the third main roll 5 that is arranged at the upper right and rotates clockwise, and is then arranged at the lower left thereof. It is wound around the fourth main roll 6 that rotates counterclockwise, discharged from the outlet 7, and sent to the next process.

  Reference numeral 8 denotes a drive source motor (for example, 1800 rpm) for rotating the four main rolls 3, 4, 5 and 6, which is hung on the drive shaft of the motor 8, and the V belt 9 is connected to the fourth belt. It is hung on the V pulley 11 provided on the input shaft of the speed reducer 10 that supports the rotation shaft of the main roll 6 of the main roll 6, and this is rotationally driven (for example, 450 rpm). The fourth main roll 6 that is pivotally supported is rotated at an appropriate speed (for example, 18 rpm or 60 m / min on the outer periphery).

  The V pulley 11 is provided with two V grooves for the V belt, and in addition to the V belt 9, another V belt 12 is hung. The V belt 12 is a second main belt. A second pulley that is hung on a V pulley 14 provided on an input shaft of a speed reducer 13 that supports the rotating shaft of the roll 4 and that is rotationally driven, decelerates the rotational speed by the speed reducer 13 and is supported by the output shaft. The main roll 4 is rotated at an appropriate speed.

  In addition to the V belt 12, another V belt 15 is hung on the V pulley 14, and this V belt 15 is attached to a reversing mechanism 16 which is a means for reversing the rotation direction of the main roll. It is connected.

As shown in FIG. 3, the reversing mechanism 16 includes a toothed pulley 17 having two V-grooves 17a for engaging the V-belt 15 and two tooth grooves 17b that engage with the toothed belt. These toothed pulleys 18 are juxtaposed with each other, and a two-tooth belt 19 in which chevron-shaped teeth are provided on both the front and back surfaces is stretched over these. Then, the toothed pulley 17 is engaged by engaging the back surface of the toothed belt 19 shown in FIG. 2 with the tooth groove of the toothed pulley 17 and engaging the surface of the toothed belt 19 with the tooth groove of the toothed pulley 18. The counterclockwise rotation of 17 can be reversed to the clockwise rotation of the toothed pulley 18.
Reference numeral 20 denotes an idler pulley that increases the winding angle of the surface of the toothed belt 19 with respect to the toothed pulley 18 in order to reliably transmit a large rotational torque while reversing the rotational direction from the toothed pulley 17 to the toothed pulley 18. It is arranged as appropriate.

  The toothed pulley 18 is provided with a V groove as well as a tooth groove engaging with both the toothed belts 19, and an input of a reduction gear 21 that pivotally supports the V groove and the rotation shaft of the first main roll 3. A V belt 23 is hung between the V pulley 22 provided on the shaft, and the first main roll 3 is driven to rotate clockwise.

  The V pulley 22 has two V grooves for the V belt, and in addition to the V belt 23, another V belt 24 is hung. The V belt 24 is connected to the third main roll 5. The third main shaft is hung on a V pulley 26 provided on the input shaft of the speed reducer 25 that supports the rotation shaft of the speed reducer 25 and is driven to rotate. The speed reducer 25 reduces the rotational speed and is supported on the output shaft. The roll 5 is rotated at an appropriate speed.

  Since the conveyance path from the second main roll 4 to the third main roll 5 is long, wrinkles do not occur in the articles to be washed such as sheets conveyed from the second main roll 4 to the third main roll 5. Thus, the rotational speed of the outer periphery of the third main roll 5 is set to be about 5% faster than the rotational speed of the outer periphery of the second main roll 4. Thereby, the to-be-washed object is conveyed in the state which was always taut, without loosening between the 2nd main roll 4 and the 3rd main roll 5. FIG.

  In order to increase the rotational speed of the outer periphery of the third main roll 5 by 5%, the outer diameter of the V pulley 26 can be made 5% smaller than the outer diameter of the V pulley 22. In addition to this, there are technically means such as changing the speed reduction rate of the speed reducer 25 or increasing the outer diameter of the third main roll 5.

In general, the V-belt is gradually worn by long-time use, but the degree of wear is large because the V-belt closer to the motor as the driving source receives a larger force, The V-belt on the side farther from the motor is less worn, and the main roll farther from the motor tends to rotate slower than the main roll closer to the motor.
For this reason, when the motor is connected to the first main roll on the upstream side in the conveyance of the object to be cleaned, and then connected to the main roll on the downstream side sequentially with the V belt, the main roll on the downstream side is caused by the wear of the V belt. However, there was a risk that wrinkles would occur in the object to be washed between the main rolls.

  Therefore, in the present embodiment, the motor of the driving source is connected to the fourth main roll 6 on the downstream side in the conveyance of the object to be washed, and then sequentially connected to the upstream side by the V belt from there. Even when the belt is worn, the main roll on the upstream side is faster to rotate, so that wrinkles are not generated on the object to be transported. Only the third main roll 5 has a different arrangement from the above rule that it is driven by the first main roll 3, but the third main roll 5 is the second main roll 4 or the first main roll 5. Since the speed is set 5% faster than the main roll 3 in advance, the article to be washed is not loosened.

  As mentioned above, although the roll finisher of this invention was shown and demonstrated concrete embodiment, this invention is not limited to these. A person skilled in the art can make various changes and improvements to the configuration and function of the roll finishing machine in each of the above embodiments without departing from the scope of the present invention.

  The roll finishing machine of the present invention can be used in the industry for manufacturing continuous laundry equipment.
