Description

[Detailed Description of the Invention] The present invention relates to a hand towel feeding machine which is new and has great industrial applicability.

Recently, there has been a hand towel supply machine that automatically winds up a used towel around a take-up roller via an interconnected delivery roller and driven roller each time an unused towel wound up in a roll is manually pulled out. However, in these conventional hand towel supply machines, the rollers for winding unused towels and used towels are pivoted at the upper and lower positions of the cabinet, and the unused towel winding rollers are separated. Since the winding operation and the winding operation of the used towel winding roller are combined to feed out the hand towel in parts, the position of the unused towel winding roller is at least the same as that of the used towel winding roller. It is necessary to set the value higher than the tangent line at the top of the used towel roll when the maximum amount is wound, and the width of expansion and contraction of the diameter of the used towel roll must be set in consideration of the looseness of the used towel winding roller. Therefore, the height of the cabinet that stores the rolls of unused towels and rolls of used towels must be designed to be considerably large, which results in an increase in the size of the hand towel supply machine.・It is a well-known fact that this has led to an increase in costs.

The present invention uses a mechanism for vertically moving an unused towel and a used towel in relation to each other.
The purpose is to completely eliminate the drawbacks of the conventional hand towel supply machine as described above.

Next, the configuration of the present invention will be specifically explained with reference to the drawings showing one embodiment.

1 is a cabinet of the hand towel supplying machine of the present invention; 2, 2, and 2 are towel holder sliding frames attached vertically to the inner surfaces of both side walls 3 and 3 of the cabinet 1; A towel holder 5 on which a used towel 4 is unrolled and rotatably placed is attached to a support shaft 6 protruding from both ends of the towel holder 5.
6, 6, and 6 so as to be vertically slidable.

The shape of the towel holder 5 is preferably such that the cylindrical rolled unused towel 4 is placed thereon so that it can be unwound and rotated, so that the shape of the towel holder 5 is shaped like a letter with the sides curved as shown in the figure.

Reference numeral 7 denotes a feed-out roller that is pivotally supported above between the cabinet side walls 3, 3, and is used to feed a rolled unused towel 4 stored and mounted in the towel holder 5.
The unrolled portion of the towel 4 is suspended and rotated in response to manual withdrawal of the rolled unused towel 4, and is pivoted downward between the cabinet side walls 3, 3 via an appropriate transmission mechanism 8. A known mechanism is provided for reaccommodating the towel dispensing section 10 suspended from the driven roller 9, that is, the used towel section, into the cabinet 1 by rotating the driven roller 9.

Reference numeral 11 denotes a presser roller which presses and clamps the towel dispensing portion 10 between it and the dispensing roller 7, and is rotatably supported between the cabinet side walls 3, 3.

12 presses and clamps a towel dispensing section 10 between the driven roller 9 and winds the towel dispensing section 10 as the driven roller 9 rotates, thereby enlarging the diameter of the rolled used towel 13. The winding rollers 14, 14 are winding roller sliding frames attached vertically to the lower inner surfaces of the cabinet side walls 3, 3, respectively, and rotatably support the winding roller 12. Rolled unused towel 4
The structure is such that the winding roller 12 can be gradually slid upward as the amount of winding of the winding roller 12 increases as the unwinding and feeding progresses, that is, the diameter of the rolled used towel 13 increases. do.

The above configuration will be explained with reference to FIGS. 1 and 2. FIG. 1 shows the hand towel supplying machine of the present invention almost before use, with a rolled unused towel 4 stored and placed in a towel holder 5. has the largest possible diameter, and the winding roller 12 is simply connected to the end of the towel feeding section 10.

In accordance with the embodiment shown in FIG. 1 above, the roll-shaped unused towel 4 gradually becomes smaller in diameter by accumulating each towel user's divided feeding by a known towel dividing mechanism (not shown). Almost inversely proportional to this, the diameter of the rolled used towel 13 wound around the take-up roller 12 gradually increases.

In this case, the rolled unused towel 4 is coreless, whereas the rolled used towel 1 is coreless.
3 is a structure wound around a winding roller 12;
Furthermore, since there is some slack in the winding around the take-up roller 12, the diameters of the rolled unused towel 4 and the rolled used towel 13 do not apparently increase or decrease in completely inverse proportion to each other. Needless to say.

When the diameter of the used towel roll 13 increases as described above, the used towel roll 13 that comes into contact with the driven roller 9 is pushed up, and thus the take-up roller 12 performs a rotational winding operation. While doing so, the winding roller sliding frames 14, 14 are slid at both ends in the upward direction of the arrow in FIG. 2, and rise to the position shown by the solid line in FIG. The outer peripheral edge of the towel 13 occupies the position shown by the two-dot chain line in FIG.

In the hand towel feeding machine of the present invention, the diameter of the used rolled towel 13 increases as described above, and the top portion 131 of the used rolled towel 13 rises due to the upward sliding of the take-up roller 12. The bottom surface of the towel holder 5 comes into contact with the top of the head 131, and as the top of the head 131 further rises, the towel holder 5 moves towards the towel holder sliding frames 2, 2,
2.2, it gradually slides upward as shown by the arrow in FIG. 2, and reaches the position shown by the solid line in FIG.

In other words, unrolling the rolled unused towel 4.
The towel holder 5 is gradually pushed up inside the cabinet 1 by the rolled used towel top portion 131 which moves upward within the cabinet 1 as it is fed out.

In the present invention, as is clear from the above-described structure and operation, as the diameter of the rolled used towel 13 increases, the towel holder 5 for storing and placing the rolled unused towel 4 is automatically moved upward. Since it is a sliding structure, the height of the cabinet can be reduced compared to the conventional mechanism described above, in which the unused towel roller and the used towel roller are supported vertically in the cabinet at appropriate intervals. It can be significantly reduced in size and has a special effect on making the hand towel supply machine more compact, smaller, and cost-reduced, and its industrial applicability is great.

In this case, the winding roller sliding frames 14, 14 are placed at the upper end portions 141, 1 as shown in the figure.
41 is arranged at an inclined position located at the center of the longitudinal width of the side walls 3, 3 of the cabinet, since the height of the cabinet 1 can be compressed by the longitudinal width of the cabinet 1, which is very preferable.
