Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for draining umbrellas which shake off water drops of umbrellas wetted by rain on the basis of inertial force acting on them.

[0002]

2. Description of the Related Art Conventional techniques of this type include, for example, Japanese Patent Application Laid-Open Nos. 5-91916 and 11-8.
As disclosed in Japanese Patent No. 3314, while a wet umbrella is pinched and conveyed by a pair of opposed water absorbing belts, there is a water absorbing belt that absorbs water droplets of the umbrella from a contact surface with the umbrella. .

[0003]

However, in such a conventional technique, when the umbrellas are sandwiched and transported, the umbrella cloths are strongly sandwiched between the water absorbing belts in a state of being overlapped with each other. Water droplets could not be sufficiently removed from portions that could not contact the water absorbing belt.
The present invention has been made in view of such problems of the prior art, and provides an umbrella draining method and apparatus that can more effectively remove wet umbrella water droplets.

[0004]

An umbrella draining method according to the present invention comprises:
Water drops adhering to the umbrella are dropped by vibrating up and down under the action of a thrust. In this method, the umbrella cloth is opened naturally and the umbrella is displaced by impact without the umbrella being pinched, so that water drops are efficiently shaken off by the action of a large inertial force on the umbrella cloth It is possible to sufficiently remove the joy of trapping water drops in the overlapping portion of the umbrella cloth.

An umbrella drainer according to the present invention is provided with a base which is reciprocated between an umbrella insertion position and an extraction position in a housing, and a motor is arranged on the base. A hammer that is vibrated in the vertical direction through a driven crank mechanism is provided, and above the hammer, an elevating rod that is integrated with a holder that holds an umbrella shingle, and whose lower end is hit with a hammer and rises and displaces, is provided. In addition to the arrangement, a return spring for returning the lifting rod to its lower limit position is provided, and more preferably, an umbrella sensor for detecting insertion and removal of the umbrella with respect to the holder is provided.

In this device, after the umbrella is inserted into the holder, the umbrella is moved in the walking direction of the owner of the umbrella based on the movement of the base, and the umbrella is moved by the action of the crank mechanism during the movement. Based on the vertical vibration of the hammer, the vertical rod, and thus the holder, for example, is subjected to a vertical vibration of, for example, about 10 to 30 Hz, in particular, a shocking upward movement for a predetermined time, so that the holder holds the ram and opens naturally. From the umbrella in the closed state, the water drops attached to the umbrella can be efficiently dropped by their inertia without restraining the water drops due to the overlapping of the umbrella cloths.
By causing the base to reach the umbrella withdrawal position, the umbrella owner can have an umbrella from which water droplets have been sufficiently removed. The base, holder and the like that have completed one job in this way return to their original positions based on the removal of the umbrella from the holder and wait for the next job.

Here, when an umbrella sensor for detecting the insertion and removal of the umbrella with respect to the holder is provided in, for example, the housing, the insertion of the umbrella can be detected and the base and other operations can be started. By detecting the removal of the umbrella, the base or the like can be returned to the original position.

Another drainer according to the present invention is provided with a base which is reciprocated between an umbrella insertion position and an umbrella extraction position in a housing, and a motor is disposed on the base and the motor is mounted on the base. A bush that is vibrated in the vertical direction through a driven crank mechanism is provided, and a penetrating rod that projects downwards integrally with a holder that holds the umbrella sword is penetrated by this bush, and the vertical A cushioning member is provided at the end of the umbrella, which is in contact with the bush. Preferably, an umbrella sensor for detecting insertion and removal of the umbrella with respect to the holder is provided similarly to the above-described device.

In this device, in particular, the same umbrella as in the previous device can be drained by transmitting the vertical vibration to the elevating rod and the holder that penetrates the bush that is vertically vibrated by the crank mechanism. In addition, by applying a downward impact to the lifting rod in addition to the upward impact, water droplets attached to the umbrella cloth can be more efficiently removed. In this case, when transmitting the vertical vibration from the bush to the lifting rod, the two are brought into contact with each other via the buffer member, whereby the generation of the collision impact and the collision sound can be advantageously reduced. Further, the stop positions of the lifting rod and the holder are specified by the contact between the bush whose operation has been stopped and the upper cushioning member, and their weight is supported by the bush, so that special positioning means and load support are provided. There is no need to provide means.

By the way, in any of these apparatuses, preferably, a traveling motor for causing the base to reciprocate is provided on the base, and a pinion driven by the traveling motor is provided on the housing side. To be engaged.

The reciprocating movement of the base can be performed by a hydraulic cylinder, a screw mechanism, a pulley mechanism, or the like.
The rack and pinion mechanism described above is most suitable in consideration of downsizing of the mechanism, accuracy of position control, speeding up, maintenance and management of pipes and ropes, cost, and the like.

Preferably, the holder comprises a rigid cylinder and an elastic sleeve disposed inside the rigid cylinder, and a direct or indirect addition between the rigid cylinder and the elastic sleeve. By supplying and discharging the pressurized fluid, the elastic sleeve is reduced in diameter and restored to its original shape, so that the holding and releasing of the elastic sleeve can be quickly and surely performed without fear of damaging a ram.

By the way, when the posture holding ring surrounding the intermediate portion of the umbrella is provided so as to protrude above the holder, the umbrella is prevented from falling down due to the vertical vibration, and the umbrella from being unexpectedly expanded. In addition, it is also possible to guide the smooth insertion of the shingle into the holder when inserting the umbrella.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional front view showing an embodiment according to the present invention. In the drawing, reference numeral 1 denotes a housing, and reference numerals 2 and 3 denote an insertion portion and an extraction portion of an umbrella provided in the housing 1, respectively. In addition, this housing 1 is not limited to simply adjusting the appearance of the exterior, but also prevents the drive unit and the like from being exposed to ensure the safety of a user of the device, and at the same time, suppresses foreign matter and dust from entering. It also functions effectively to ensure smooth operation for a long period of time. Here, as shown in a plan view in FIG. 2, two support rods 4 extending in parallel with each other and horizontally are arranged on the bottom of the housing 1, and the support rods 4 By supporting the base 6 with the umbrella, the base 6 can be reciprocated between the insertion part 2 and the extraction part 3 of the umbrella.

Here, a motor 7 is provided on a base 6 and an output shaft of the motor 7 is connected to each pulley 8, as apparent from a longitudinal sectional side view in FIG.
9 and a V-belt 10 are connected to a crank mechanism 11. Here, the crank mechanism 11 is constituted by connecting one end of a connecting rod 14 to an eccentric crank pin 13 of a crankshaft 12 driven to rotate by a V-belt 10.
The other end of 4 is connected to a hammer 17 provided with a slider 16 which is guided by a guide rail 15 in vertical displacement. Then, the upper end of this hammer 17 is
9 is positioned so as to face the lower end surface of a lifting rod 21 integral with a holder 20 that holds the holder 9 vertically.

The elevating rod 21 is guided by a bush 23 mounted on the base 6 via a column 22 to guide the elevating displacement in a vertical position, and is disposed around a lower end portion thereof. And a return spring 2 having an upper end connected to the bush housing 24, respectively.
5 and is held in the lower position. It is to be noted that the holding of the elevating furnace 21 at the lower limit position is performed by arranging it around the upper end portion of the elevating rod 21 and assisting with the springs 26 seated on the holder 20 and the bush housing 24, respectively. Is more preferably specified.

The lower end surface of the lifting rod 21 at the lower end position is slightly lower than the upper end position of the upper end surface of the hammer 17 so that the hammer 17
In addition, the lower end surface of the lifting rod 21 is hit on the basis of the upward displacement caused by the action of the crank mechanism 11 under acceleration, so that the lifting rod 21 and the holder 20 are moved together with the umbrella 18 against the spring force of the return spring 25. It can be ascendingly displaced. On the other hand, the lifting rod 21 descends with the downward displacement of the hammer 17,
After reaching the lower limit position specified by 5 and 26, the next hit by the hammer 17 is awaited.

Here, more preferably, the holder 20
As is evident from FIGS. 1 and 4, there is provided a posture holding ring 27 projecting upwardly therefrom and surrounding the intermediate part of the umbrella.

Further, as shown in an enlarged sectional view of FIG. 5, the holder 20 includes a rigid cylindrical body 28,
An elastic sleeve 29 is hermetically attached to the inner peripheral side of the umbrella.
As shown in FIG. 5A, the rigid cylindrical body 28 is inserted into the holder 20 to a position where the holder 20 reaches the bottom plate 20a.
Pressurized air is supplied between the elastic sleeve 29 and the elastic sleeve 29 to reduce the diameter of the elastic sleeve 29 as shown in FIG. Thus, it is possible to securely hold the stone foot 19 and sufficiently remove damage or other fear of the stone foot 19.

On the other hand, when releasing the holding, the compressed air between the cylindrical body 28 and the sleeve 29 is discharged, so that the elastic sleeve 29 is returned to its original shape as shown in FIG. The sleeve 29 is thereby released from elasticity, thereby removing the restraint of the sleeve 29 against the ram 19.

In the place shown in FIG.
Although the compressed air as an example of the pressurized fluid is directly supplied between the elastic sleeve 29 and the elastic sleeve 29, as shown in a cross-sectional view in FIG.
The rubber tube 30 is disposed between the rubber tube 30 and the other end of the rubber tube 30 whose one end is closed. Radial deformation is also possible, which eliminates the need for an air-tight or liquid-tight connection between the cylinder 28 and the sleeve 29.

Further, in this device, as shown in a plan view in FIG. 7, a traveling motor 31 for causing its own reciprocating motion is disposed on the base 6, and the output shaft of the motor 31 is provided with a deceleration. The pinion 33 is mounted via the machine 32.
Here, as shown in FIG. 3, the pinion 33 is provided so as to protrude toward the rear surface of the base 6, and is engaged with a rack 34 horizontally mounted on the housing 1.

Further, as shown in FIG. 3, an umbrella sensor for detecting the insertion and removal of the umbrella 18 with respect to the holder 20, for example, a light-emitting and light-receiving element, is provided on the left and right sides of the base 6 with the holder 20 therebetween. An optical sensor 35 including a reflecting mirror or a limit switch (not shown) is provided. In FIG. 3, reference numeral 36 denotes a cover for protecting the motors 7, 31, the crank mechanism 11, and other movable parts attached to the base 6 from water droplets, and reference numerals 37, 38 denote a water droplet discharge port and a caster, respectively.

In FIG. 2, reference numerals 39, 40, and 41 denote a sensor for detecting that the base 6 is at the insertion position of the umbrella 18, a sensor for detecting that the base 6 is at the draining operation position, and the base 6, respectively. 5 shows a sensor that detects that the umbrella 18 is at the extraction position.

In the apparatus configured as described above,
When the umbrella 18 wet with rain is inserted from the insertion portion 2 and the stone 19 is seated on the bottom plate 20a of the holder 20, the holder 2 is detected based on the detection of the insertion of the umbrella 18 by the optical sensor 35.
0 elastic sleeve 29 is reduced in diameter and its stone foot 1
9, whereby the holder 20 maintains the umbrella 18 in an upright state with the assistance of the posture holding ring 21.

Thereafter, the traveling motor 31 on the base 6 drives the pinion 33, so that the base 6, the holder 20 and the like are moved under the engagement of the pinion 33 and the rack 34.
When the base 6 reaches the sensor 40 together with the base 8, the movement of the base 6 is temporarily stopped, while the motor 7 is operated.

As a result, the crank mechanism 11 is operated at a required speed to move the hammer 17 up and down, so that the lifting rod 21 and the holder 20, and eventually the umbrella 18, are shocked by the hammer 17 to buffer the return spring 25. Under the action, while being upwardly displaced by impact, the return spring repeatedly repeats the vertical vibration which is lowered to the lower limit position, whereby the water droplets attached to the umbrella 18 which is naturally held open by the holding ring 21 are removed. In particular, based on the inertial force at the time of the upward displacement, almost all of the umbrella cloth is efficiently knocked down without pinching water drops. Moreover, here, the umbrella cloth of the umbrella 18 in the naturally opened state can be relatively freely deformed and displaced in accordance with the vertical vibration, so that the drop efficiency of the water droplet can be further enhanced.

After the umbrella 18 is subjected to such vibration for a predetermined period of time to drop the water droplets sufficiently, the motor 7 is stopped and the running motor 31 is restarted, so that the base 6 and the umbrella 18 are moved. The base 6 is moved to the extraction portion 3 of the umbrella 18 detected by the sensor 41, and at the same time when the base 6 reaches the extraction portion 3, the elastic sleeve 29 of the holder 20 is elastically restored to its original shape. Let me return, Ishibushi 1
9 is released.

Thereafter, when the optical sensor 35 can no longer detect the presence of the umbrella 18 due to the removal of the umbrella 18 from the extraction portion 3, the traveling motor 31 is operated in reverse to operate the base 6 and the holder 20. And the like are returned to the original position corresponding to the insertion section 2 and stopped there under the action of the sensor 39.

The apparatus that has completed a series of operations in this way repeats the same steps as described above by inserting the next umbrella 18. Thus, according to this device, the umbrella 18 is naturally opened, and a vertical vibration accompanied by a shocking upward movement is applied to the umbrella 18 so that water droplets are generated by the inertial force acting on the umbrella cloth. It can be dropped efficiently without being confined.

FIGS. 8 and 9 are cross-sectional views of a main part showing another embodiment. Specifically, the upper end of the connecting rod 14 of the crank mechanism 11 is connected to a slider 16 guided vertically by a guide rail 15 and a bush 52 is attached to the slider 16 via a bush housing 51. And the holder 20
The lifting rod 21 protruding downward from the bush 52 is slidably penetrated through the bush 52, and the upper and lower ends of the lifting rod 21 are made of a spring, a rubber-like elastic body, or the like. Arrange the buffer members 53 and 54 that can be
These buffer members 53 and 54 can be brought into contact with the bush 52, directly with the bush housing 51, and the configuration of other parts is almost the same as that of the above-described device.

The vertical vibration of the holder 20 by this device is as follows.
The operation of the crank mechanism 11 causes the slider 16 and the bush 52 to vibrate up and down.
The transmission can be performed by transmitting to the lifting rod 21 via the upper and lower cushioning members 53 and 54. In this case, the bush 52 contacts the upper cushioning member 53 when the holder 20 rises, and contacts the upper cushioning member 53 when the holder 20 descends. Will come into contact with the lower cushioning member 54, respectively.
The holder 20 and, consequently, the umbrella 18 held by the holder 20, are subjected to a shock directed in the vertical direction. Therefore, water droplets adhering to the umbrella cloth fall more efficiently by the increased number of impacts than in the above-described device.

Further, in this device, when the vibration of the bush 52 is stopped, the holder 20 and the lifting rod 2 can be moved regardless of the stop position between the upper limit position and the lower limit position.
1 is stopped by being supported on the bush 52 via the upper cushioning member 53 under the action of its own weight or the like,
It is not necessary to provide special positioning means and load supporting means for the holder 20 and the like.

[0034]

As is apparent from the above description, according to the present invention, a simple and compact device can be used.
Compared to the conventional technology of holding an umbrella with a water-absorbing belt, water drops on the umbrella can be efficiently shaken off and removed, and the risk of damage to the umbrella can be eliminated. It is possible to obviate the necessity of the above and sanitary post-treatment.
