Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ceiling traveling type hoist, and more particularly to a ceiling traveling type hoist used for transferring an object from one place to another, and is mainly used for storage of undelivered return parcel post and window delivery service. Regarding traveling hoist.

[0002]

[Background of the invention]

 Usually, there are about 300 parcels to be returned to and from the post office, which has a large number of items stored, and several thousand parcels per day during the busy season. They will be organized and delivered to the shelves, and will be waiting for receipt. However, it is difficult to secure a space because the number is very large, and a lot of energy was spent on labor for storage and delivery processing.

In view of the above situation, a system has recently been developed that uses a barcode to eliminate the waste of work labor, time and storage space. Even with this system, parcel post Since workers had to go to the shelves and manually load and unload items, their time and labor were still left behind.

[The purpose of the device]

 The present invention promotes the above-mentioned system by improving it so that the worker can automatically transfer the target object of the parcel mail while the operator stays in the predetermined position of the counter. It is an object of the present invention to provide an overhead traveling hoist that is free from any bra or rattling and can be operated smoothly and without deviation.

[0005]

[Means for Solving the Problems]

 In order to achieve this object, the overhead traveling hoist according to the present invention comprises a current collecting device and a traveling mechanism slidably contacted with a traveling rail installed above the indoor, and a drive motor arranged below the traveling mechanism. And four drums that were conducted with the drive motor and meshed with each other with bevel gears and were arranged at a 90 degree pitch, a belt body with its upper end fixed to the drum, and a lower end of the belt body. It is characterized by having an elevating body and an operating body for an object attached to the elevating body.

[0006]

[Action]

 With the above-mentioned configuration, it is possible to obtain a smooth and accurate operation without causing any rattling or rattling in the operation of the target object, and generally in the vertical movement of the lifting body provided with the operating body for clamping. As a result, the workability is improved, and it is possible to largely eliminate the waste of time, labor, and storage space for the object.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a front view of an overhead traveling hoist according to the present invention, FIG. 2 is a side view of the same, FIG. 3 is a plan view of a hoisting mechanism, and FIG. 4 is a plan view of an elevating body.

In these drawings, reference numeral 1 denotes a rail provided above the room, particularly along the ceiling. The rail 1 is made of a steel material having an H-shaped cross section, and on both sides of the rail, protrusions 1a and 1a are formed on the upper sides of the rails so as to be in sliding contact with a current collector (pantograph), which will be described later, and on the upper surface of the lower flange. Is also formed with ridges 1b, 1b which engage with the wheels described later and guide the traveling.

On the other hand, reference numeral 2 in the figure denotes a cover for covering the traveling mechanism and the winding mechanism. The cover 2 has a large opening below it and an opening for avoiding the rail 1 is formed at the center of the upper surface. A current collector (pantograph) 3 is attached to the curved inner wall of the rail 3, and the tip of the current collector 3 is slidably contacted with the ridges 1a and 1a of the rail 1 described above.

Reference numeral 4 in the drawing denotes a drive motor in the traveling mechanism, and a drive shaft of the drive motor 4 is connected with a conductive element such as a belt 5.5 or a shaft 6 so that the traveling wheels 5.5 are projected. It is designed to make rolling contact with the articles 1b and 1b.

Further, an elevating mechanism is provided below the traveling mechanism. This elevating mechanism is provided with a drive motor 7, and four drums 8, 8 ... Are provided around the drive motor 7 with a 90-degree pitch. The drums 8 and 8 have bevel gears 9 and 9 attached to both ends of their shafts, and the bevel gears 9 and 9 are meshed with each other. Further, it is said that any one of the drums 8, 8 ... Is connected to the drive motor 7 by the conduction belt 10 so that the drive force of the drive motor 7 is transmitted, and the drive force is the bevel gears 9 and 9. .. are conducted in synchronization with the respective drums 8.

Further, one end of a stainless belt 11, 11, ... Is fixed to each of the above-mentioned drums 8, 8 .... By the rotation of each of the drums 8, 8 ,. Is rolled up or unrolled. That is, since the four drums 8 ... rotate synchronously, the four stainless belts 11, 11 ... Synchronously maintain the same length.

The lower ends of the stainless belts 11, 11, ... Are fixed to the lifting body 12, and the lifting bodies 12 are moved up and down in accordance with the movement of the stainless belts 11, 11. A slide plate 13 is provided on the lower surface of the lifting body 12, and the slide plate 13 includes a reduction drive source 14 attached to the elevation body 12 and a shaft 16 connected to the reduction drive source 14 and a belt 15. It is operated by gears 17 mounted on both ends.

Further, a pair of clampers 18 and 18 are provided on the lower surface of the slide plate 13 described above. The clamper 18, 18 has an L-shaped crossing portion 19 19, which is formed at the rear portion thereof, and rack gears 20, 20 are formed at the opposite portions of the crossing portion 19, 19 with each other. The drive gear 21 is meshed with the gear 20, and the rotation of the drive gear 21 causes the clampers 18, 18 to move in and out synchronously.

Further, in the figure, 22 and 22 are slide guides to and from a shelf provided on both sides of the slide plate 13, and rollers 23, 23 ... It will be fitted to the guide groove.

The overhead traveling hoist according to this embodiment is configured as described above. That is, the hoist, which has been run against the intended parcel post (barcode processing using a personal computer), moves the lifting body 12 up and down by the stainless belts 11, 11 ... In front of the shelf, and then slides the slide plate 13. Move it into the shelf, clamp container A with clamper 18 and pull it out to move it to the desired position. This operation is, of course, reversed when stored on the shelf.

In the present embodiment, the parcel post that has not been brought back has been described as the object to be transferred, but it is not limited to this and it is obvious that it can be applied to factories and warehouses, and in that case, slide plates and the like Need not be present, and only the clamping operation of the mounted object may be performed.

[0018]

[Effect of the device]

 Since the overhead traveling hoist according to the present invention uses the belt body to obtain the vertical movement of the elevating body, it is possible to obtain a smooth and stable operation without causing any rattling or rattling. Therefore, it is highly reliable even for computer control and radio control, and there is no risk of failure or mistake.
