Abstract

PURPOSE:To adjust continuously variably the length of transfer by fitting an extension stand to an inclinable conveyer stand and supporting rotatably a drive wheel and lower front idler wheel in both end sides and tail and front idler wheels in both end sides of the extension stand respectively to train a conveyer belt over these wheels. CONSTITUTION:While an extension stand 2 is extendably slidably fitted to a conveyer stand 1, both ground contacting wheels of pivotal fulcrum 0 are rotatably supported in one lower end side of the conveyer stand and lower front idler wheels 4 below the extension stand 2. Also, tail idler wheels 5 and lower front idle wheels 6 are rotatably supported in both end sides of the extension stand 2 respectively while an endless conveyer belt 7 is trained over a drive wheel 3, the tip idle wheels 6, tail idler wheels 5 and lower front idler wheels 4. When the extension stand 2 is put in and out of the conveyer stand 1, the extension stand 2 is extended and contracted by the movement of the front idler wheel 6 and tail idler wheel 5 while the conveyer belt 7 engages repetitively the respective wheels 6, 5, 4 so that the length of transfer of the conveyer can be continuously variably adjusted.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor system for conveying goods, which is capable of adjusting the length and angle of inclination of a conveyor belt for conveying goods.

0002

[Prior Art] Conventional conveyor devices of this type have the ability to adjust the conveying length in several stages, such as three stages, and also to adjust the inclination using pneumatic pressure or a pressure cylinder. .

0003

[Problem to be Solved by the Invention] However, since the conveyance length is limited to expansion/contraction adjustment in several stages, for example, when loading a truck, the loading position of the truck changes little by little. If it is not possible to adjust the movement of the conveyor by expanding or contracting it each time to the optimal loading position inside, and if it is not possible to move the truck side, loading work will be time consuming and work efficiency will be poor. Also, for example, when transporting weighed grain bags to a predetermined location and stacking them,
If the conveyance length could only be adjusted to a limited range, there were problems such as poor workability.

0004

[Means for Solving the Problems] The present invention has been devised to solve such problems and to further improve workability by adjusting the conveyance length steplessly. A long conveyor table that can be rotated around the fulcrum point 0 to change its inclination is fitted with an extendable and slidable extension table.
A drive wheel and a lower end idler are mounted on both ends of the conveyor table, and a rear end idler and a front end idler are mounted on both ends of the extension table. It is constructed by folding and hanging an endless conveyor belt over a ring and a floating wheel at the bottom of the tip, and a large number of round bars inscribed in the conveyor belt are mounted on shafts at predetermined intervals on the upper part of the conveyor table, which spans almost the entire length. In addition, inside the extension table between the leading idler wheel and the rear end idler wheel, a large number of idler wheels with which the conveyor belt touches each other vertically are mounted at predetermined intervals, and the lower part of the conveyor table has a grounding ring at the tip. The base of the supporting leg is pivotally connected, and a supporting punch, which is movable by a motor provided on the conveyor table, is interlocked with the supporting leg.

[0005]

[Operation] Therefore, when the extension table is slid in and out of the conveyor table, the conveyor belt remains folded and engaged with each ring, and the extension table expands and contracts due to the movement of the front idler wheel and the rear end idler wheel. This allows the conveyor length to be adjusted steplessly.

[0006]

[Embodiment] Fig. 3 shows a side view of the entire conveyor device.A long conveyor table 1 made of a parallel frame has a long extension table 2 shorter than the conveyor table 1 and made of a parallel frame that can extend and retract and slide freely. At the bottom of one end of the conveyor table 1, both ground wheels 14, which serve as rotational fulcrums when the conveyor table 1 is tilted, are mounted on a shaft, and a motor 15 and a motor 15 attached near the ground wheels 14 are mounted on the lower part of one end of the conveyor table 1. A drive wheel 3 mounted on the other end of the conveyor stand 1 is transmission-connected via a pulley belt 16, and a large number of round bars 8 are mounted on the upper part of the conveyor stand 1 at predetermined intervals over the entire length of the conveyor stand 1. A lower end idler wheel 4 is mounted on a shaft at the lower part of the conveyor table 1 near the other end of the extension table 2, and
Guide wheels 17, 18 are provided above and below near the drive wheel 3.
19 are respectively mounted on shafts, and a rear end idler wheel 5 and a front end idler wheel 6 are respectively mounted on shafts on both ends of the extension table 2, and a large number of idlers are mounted at predetermined intervals between the two wheels 5 and 6. The wheel 9 is mounted on an axis, and the drive wheel 3, the front end idler wheel 6, the rear end idler wheel 5, and the lower end idler wheel 4 are folded back and engaged, and each round bar 8, each idler wheel 9, and a guide wheel 19 ,18
, 17, an endless conveyor belt 7 is hung around them so as to be in contact with them.

Both brackets 20 provided on both sides of the lower part near the middle of the conveyor table 1 have both coaxial ground wheels 10 at their tips.
A female threaded body 22 is screwed into a screw punch 21 which is pivotally connected to the bases of both supporting legs 11 and which is rotated forward and backward by a motor 12 provided at the lower part of the tip end of the conveyor table 1. The distal end portions of both supporting punches 13 which are rotatably connected to each other are freely rotatably connected to a horizontal punch 23 which is horizontally suspended across the intermediate portions of both supporting legs 11.

Therefore, when the conveyor device is not used, the extension table 2 can be deeply inserted into the conveyor table 1 and the supporting legs 11 can be folded down to make it compact, as shown in FIG. ring 11
, 14, and when used, when the motor 12 is started, the female screw body 2
2, the conveyor table 1 and the extension table 2 can be tilted while tilting both the support legs 11 in the upright direction via the support punch 11, as shown in FIGS. 1 and 5, and the motor 15 When activated, the conveyor belt 7 is driven by the drive wheel 3, and as it is, the conveyor belt 7 becomes the shortest conveyance length L1 as shown in FIG. This means that it can be loaded inside.

Furthermore, when the extension table 2 is moved in and out of the conveyor table 1 by sliding it, the conveyor belt 7 remains folded and engaged with each wheel 6, 5, and 4, and the front end idler wheel 6 and the rear end idler By the movement of the wheel 5, the extension table 2 is brought into a state of expansion and contraction, and the conveyance length of the conveyor can be adjusted steplessly until it reaches the longest conveyance length L2, as shown in FIG.

0010

As described above, in the present invention, the extension table 2 can be simply moved in and out of the conveyor table 1 by sliding it in and out, and the conveyor belt 7 can be folded back and engaged with each of the wheels 6, 5, and 4. By the movement of the front end idler wheel 6 and the rear end idler wheel 5, the extension table 2 becomes expandable and retractable, making it possible to easily and steplessly adjust the conveyor conveyance length. The conveying surface of the conveyor belt 7 can be well supported by the idler wheel 9, and the inclination of the conveyor table 1 can be reliably and favorably changed while rotating the supporting leg 11 by the supporting punch 13 moved by the motor 12. It has the advantage of having a simple structure and being able to be suitably implemented.
