Abstract

PROBLEM TO BE SOLVED: To prevent excessive turning of a guide rail so as to stop an article hoisting tool at a position where good workability is obtained in a loading and unloading work machine which hoists an article by the article hoisting tool suspended on the guide rail which turns horizontally and travels. SOLUTION: This work machine is constituted in such a manner that a guide rail 2 is provided at an upper end of a support column 1 which is erected in such a manner that it can turn horizontally and an article hoisting tool is provided along this guide rail 2 in such a manner that it can travel transversely. In this case, a turn resistance mechanism 4 which gives resistance to the horizontal turn of the guide rail 2 and in which resistance against the turn increases most and the direction of the guide rail 2 for the support column 1 becomes stable is provided. Moreover, the stable direction of the guide rail 2 for the support column 1 can be changed by adjusting the turn resistance mechanism 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading / unloading machine used for moving goods such as paddy bags and cardboard cases on a pallet and unloading goods from a carrier.

[0002]

2. Description of the Related Art As a loading and unloading machine, a horizontal guide rail is provided at the upper end of an upright supporting column so as to be horizontally rotatable. There is one of the structure. The articles suspended by the article suspenders of this cargo handling machine can be moved to an arbitrary position by manually moving the article suspenders along the horizontal guide rails or rotating the horizontal guide rails horizontally. I have.

[0003]

Since the horizontal guide rail of the above-mentioned loading and unloading machine rotates horizontally with a small force, the stop position with respect to the column is not determined. For this reason, when the horizontal guide rail is too far away from the hanging position of the article, it is necessary to perform an operation of picking up the article hanging tool. Therefore, an object of the present invention is to improve the workability by making it easy for the horizontal guide rail to stop almost at the midpoint between the hanging position and the descending position of the article.

[0004]

According to the present invention, a guide rail 2 is provided at the upper end of an upright support column 1 so as to be horizontally rotatable, and an article hanger 3 is provided so as to be able to move laterally along the guide rail 2. In the loading / unloading machine, there is provided a rotation resistance mechanism 4 for imparting resistance to the horizontal rotation of the guide rail 2 and for maximizing the rotation resistance to stabilize the direction of the guide rail 2 with respect to the column 1. Further, by adjusting the rotation resistance mechanism 4, the direction in which the guide rail 2 is stabilized with respect to the support 1 can be changed.

[0005]

In the loading and unloading machine of the present invention, since the guide rail 2 has a resistance to horizontal rotation, the article suspending device 3
By moving the position where the horizontal rotation resistance of the guide rail 2 becomes the largest between the hanging position and the unloading position of the article, the article hanging tool does not become too far from the working position when the When the guide rail 2 is lightly pushed toward the work center when the hand 3 is released, the guide rail 2 stops at the work center and stands by, thereby improving workability.

[0006]

Next, embodiments of the present invention will be described with reference to the drawings. The column 1 is vertically erected on a trolley 10, and the trolley 10 is provided with weights 11 horizontally below and below the column 1, and a pair of left and right wheels 12, front and rear at the bottom.
13 are provided. Reference numeral 14 denotes a jack bolt to be installed at a fixed position. In addition, the column 1 connects the lower column 15 and the upper column 16 of substantially the same length, and the vertical column 19 is supported by bearings 17 and 18 which are provided above and below the upper column 16 so as to protrude vertically. It is pivoting. The mounting bracket 20 of the guide rail 2 is fixed to the vertical support shaft 19, and the collar 5 having a part of the outer peripheral surface chamfered 21 is externally fitted and is prevented from rotating by the bolt 22.

A bolt 23 is projected from the upper support 16 at the same height as the collar 5, and a pressing member 24 to which a sliding member 6 such as a brake pad is fixed is fitted to the tip of the bolt 23. At 25, the pressing member 24 is attached to the peripheral surface of the collar 5 by a washer 26 and nuts 27 and 28. By rotating the nuts 27 and 28, the pressing force of the pressing member 24 against the collar 5 can be changed. Since the sliding member 6 is pressed against the outer peripheral surface of the collar 5 at the mounting portion of the guide rail 2, there is a slight resistance when the guide rail 2 rotates horizontally, and the sliding member 6 is attached to the chamfered portion 21 of the collar 5. The rotation resistance mechanism 4 is configured such that the guide rail 2 is hardly rotated left and right when pressed, and is lightly fixed. The position where the guide rail 2 is lightly fixed can be achieved by changing the fixed angle position of the collar 5 with respect to the vertical support shaft 19.

The guide rail 2 is provided with a hanger 29 movably along the longitudinal direction. A chain block 30 is attached to the hanger 29, and the article hanger 3 is attached to the lower end of a chain 31 hung from the chain block 30. Is installed. When moving an article with the cargo handling machine configured as described above, the article rail 3 is horizontally rotated so that the article hanging device 3 comes on the article, and is horizontally moved along the guide rail 2 to move the chain block 30. When driven, the article hanging tool 3 is lowered to catch the article. Then, the chain block 30 is driven again to lift the article, the article hanging tool 3 is moved to the article unloading position, and the chain block 30 is driven to drop the article hanging tool 3 and release the article. When the article suspending tool 3 is not used, the guide rail 2 is stopped at that position by lightly pushing the guide rail 2 to the stop position set substantially at the center between the article suspending position and the unloading position.
