Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand towel manufacturing device, and more particularly to a hand towel manufacturing device for manufacturing a hand towel in a roll shape from a sheet-shaped hand towel material.

[0002]

2. Description of the Related Art Commercially available hand towels (rolled hand towels) wound in a roll are provided in entertainment facilities such as pachinko parlors and game centers as well as restaurants. In recent years, a small hand towel manufacturing apparatus has been developed which is installed in each store and manufactures a hand towel in a roll shape from a sheet-shaped hand towel material. For example, Japanese Patent No. 330266
That is No. 2 “rolling hand towel manufacturing equipment”. A conventional hand towel manufacturing device stores a long sheet-shaped hand towel material in a material storage section, a housing having a discharge port for discharging a hand towel made from the hand towel material, and a material stored by the electric motor by the electric motor. Roller transfer type transfer means for the hand towel material from the storage part to the discharge port, cutting means for cutting the hand towel material during transfer to the size of one hand towel, and water content for the hand towel material during transfer or the hand towel after cutting. It is provided with a humidifying means to be included and a winding means for winding the wetted towel into a roll shape. The hand towel material is formed with perforations so that it can be easily cut for each length of one hand towel.

Of these, the winding means is a belt conveyor in which a conveyor belt is stretched between a winding roller used for winding a hand towel and a driven roller, and the winding means is wound from the front belt portion of the conveyor belt. The hand towel making guide member is provided along the outer periphery of the region reaching the back belt portion through the portion wound around the roller and has a hand towel making passage formed between the hand towel making passage and the belt conveyor. The front belt portion is an upper portion of the rotating conveyor belt (a portion from the driven roller toward the winding roller). The back belt portion is a portion below the conveyor belt (a portion from the winding roller toward the driven roller). On the hand towel making guide member, a large number of small uneven portions are formed in the entire region from the middle stream portion to the downstream portion of the hand towel making passage side facing the front belt portion. When the tip portion of the hand towel material introduced from the outside into the introduction gap comes into contact with the uneven portion, the tip portion is started to be rolled. Further, the hand towel preparation guide member is configured such that an area facing the portion wound around the winding roller is a fixed belt curved along the winding roller. A limit switch for stopping power transmission to the electric motor of the transfer means is externally provided near the outside of the fixed belt. Furthermore, the passage for creating a hand towel is a take-up roll for winding the hand towel material in the upstream portion (the area facing the front belt portion) and the middle portion (the area facing the winding roller). It is composed of a gap and a discharge gap of the rolled towel in the downstream portion (a region facing the back belt portion).

The operation of the conventional hand towel manufacturing apparatus will be described. The transfer material transfers the hand towel material from the material storage unit to the discharge port. During this transfer, the hand towel material is cut into one sheet of hand towel by a cutting means. Moreover, the moisturizing means causes the hand towel material or the hand towel after cutting to contain water. Then, the hand towel is wound into a roll by the winding means, and the created hand towel is discharged from the discharge port. In particular, in the operation of the winding means, when the hand towel material is introduced into the introduction gap from the outside with the rotation of the conveyor belt, the tip portion of the hand towel material is rubbed at the midstream portion (intermediate portion) of this gap. It abuts the concave and convex portion with high resistance. As a result, the tip end portion of the hand towel material is started to be rolled. After that, the hand towel material is gradually rolled up due to the large number of uneven portions until it passes through the downstream portion of the front belt portion of the introduction gap. Next, the hand towel material passes through the winding gap. On this occasion,
The hand towel material passes through a minute gap between the portion of the conveyor belt curved along the winding roller and the portion of the hand towel forming guide member parallel to the portion. Therefore, the hand towel material is further rolled up to have a larger diameter. as a result,
A part of the rubber fixing belt is extruded in the outer peripheral direction. Therefore, the limit switch is turned on by a part of the fixing belt protruding outward against the elastic force of the rubber. Therefore, the power transmission to the electric motor of the transfer means is stopped, and the feeding of the hand towel material to the hand towel making passage is stopped.

At this time, the rotation of the conveyor belt is continued. Therefore, only the tip of the hand towel material is pulled downstream with the middle part fixed. As a result, one piece of hand towel is cut from the furthest perforation. The hand towel after cutting is completely wound while rolling in the downstream portion of the winding gap and the discharge gap, and is discharged from the discharge gap to the outside as a rolled hand towel.

[0006]

By the way, in the hand towel making guide member of the conventional hand towel making apparatus, as described above, from the midstream portion to the downstream portion of the hand towel making passage side, the area facing the front belt portion. A large number of small uneven portions were formed in the entire range. Therefore, when the hand towel material is wrapped too early and the preset cutting position of the hand towel material shifts to the base side of the hand towel material rather than the perforation, it is not possible to smoothly cut one hand towel. was there.

On the other hand, the motor 501 rotates the winding roller 503 in the clockwise direction, and the conveyor belt 506 rotates accordingly. As a result, the sheet material 2a is drawn into the conveyor belt 506 from the inlet of the hand towel making passage a and wetted with water (or hot water) sprayed from the nozzle 9. The sheet material 2a is further transported on the conveyor belt 506. After that, it comes into contact with the three rows of winding start projections 511b formed on the lower surface of the downstream portion of the upper guide plate 508, and winding is started as shown in FIG. At this time, the feeding speed of the sheet material 2a by the sheet material supplying section 4 and the drawing speed of the sheet material 2a by the winding mechanism section 5 are the same.

When the leading end of the wound sheet material 2a reaches the outer periphery of the winding roller 503, as shown in FIG. 14, the wound sheet material 2a resists the spring force of the spring member 512. The limit switch 510 is turned on by the moving cover plate 507 protruding outward. Upon receiving the operation signal of the limit switch 510, the control unit 15 causes the motor 401
To stop. As a result, the rotation of the supply roller 404 is stopped. Therefore, the sheet material 2 whose feeding operation has stopped
A is pulled by the winding roller 503, and the tension is increased. As a result, as shown in FIG. 15, the sheet material 2a is cut at the perforations L. In this case, the sheet material 2
Since a is wet, it is easier to cut than when it is dry. At the time of this cutting, the winding end of the sheet material 2a rides on the winding roller 503 and is held between the conveyor belt 506 and the moving cover plate 507. After that, the cut sheet material 2a is transported further downstream by the conveyor belt 506 while being further wound, and finally falls from the discharge gap (FIG. 16). The discharged hand towel falls on the tray 10 through the discharge port 1c. The control unit 15 stops the operation of the motor 501 after a predetermined time from the operation of the limit switch 510, and the winding roller 50
The rotation of 3 stops. If it is desired to stop the production of the hand towel during the production, the stop switch 1f is pushed.

Thus, the hand towel making guide member 53
Since the winding start projection 511b is provided only on a portion of the side of the hand towel making passage a facing the end on the side of the winding roller 503 of the front belt portion, as in the conventional hand towel manufacturing apparatus, for example, a sheet material The beginning of winding has a concavo-convex portion (corresponding to the winding start protrusion 511b) in a wide range from the middle stream portion to the downstream portion of the hand towel making passage of the hand towel making guide member facing the front belt portion. Slower than. Therefore, the preset cutting position of the sheet material 2a can be always on the formation position of the perforation L or on the leading end side of the sheet material 2a. As a result, one hand towel can be smoothly cut at an accurate cutting position without causing a cutting error. Further, since the portion of the hand towel preparation guide member 53 that is wound around the winding roller 503 is not the conventional fixed belt having elasticity but the rigid movable cover plate 507, the durability of the hand towel preparation guide member 53 is improved. be able to. However, a fixed belt (not shown) may be adopted instead of the moving cover plate 507. Further, the winding start protrusions 511b are arranged in three rows in the transport direction of the sheet material 2a, and the winding start protrusions 511b are higher in the second and third rows than in the first row. Since it is configured, the leading end of the sheet material 2a can be started accurately and smoothly.

[0037]

According to the present invention, the winding start projection is provided only on the portion of the hand towel making guide member on the side of the hand towel making passage that is opposite to the end of the front belt portion on the side of the winding roller. The cutting position of the wet hand towel material can be always on the perforation forming position or on the tip side of the hand towel material. As a result, there is almost no mistake in cutting one piece of hand towel, and the hand towel can be cut smoothly at an accurate cutting position.

According to the third aspect of the present invention, in the hand towel preparation guide member, the portion wound around the winding roller is not the fixed belt having elasticity but the rigid movable cover plate. The durability of the production guide member can be improved.

Further, according to the invention of claim 4,
Since the winding start projections are arranged in a plurality of rows in the direction in which the hand towel material is transferred, and the winding start projections are configured to become higher toward the downstream row, it is possible to start winding the tip end of the hand towel material accurately and smoothly. it can.
