DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor used in a greenhouse for plant cultivation, a room for processing various products, and other various working rooms.

[0002]

2. Description of the Related Art Conventionally, for example, in a large vinyl house for plant cultivation, as a means for transporting a seedling box or the like in which seedlings are planted to a cultivation bench installed in the house, a large number of rollers are provided on both left and right sides of an underframe. Are arranged in one side of the above bench, and a long simple roller conveyor rotatably supported in two rows is generally used.

However, if the above-mentioned roller conveyor is arranged in the house, it occupies a precious space in the house, which may hinder various subsequent operations. In the past, roller conveyors were placed in the house when loading and unloading seedling boxes, etc., and were taken out of the house after use.However, a great deal of labor and time was required to transport and arrange heavy roller conveyors. And the improvement was eagerly awaited.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to enable a conveyor in a work room such as a house to be deployed at a predetermined position when used, and to be folded into a convergent state without taking up space when not in use. Make it an issue.

[0005]

In order to solve the above-mentioned problems, according to the present invention, a plurality of columns are erected on a straight line at intervals, and arms having the same length for each of the columns can be turned on a horizontal plane. As described above, a plurality of slender conveyors, each of which is rotatably supported at the base end of the arm, and each of the above-mentioned arms, on which a conveying means is supported along a longitudinal direction on a slender underframe, are rotatably supported, respectively. , A parallel movement link mechanism formed by each of the arms and the plurality of conveyors alone,
We propose a folding conveyor.

[0006] The "transporting means" of the slender conveyor alone in the present invention includes rollers, sprockets and chains, pulleys and belts, and other various transporting means. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0007]

Referring to FIGS. 1, 2 and 3, on one side of a long cultivation bench (F) installed in a greenhouse, a pillar (1)... Standing at equal intervals on the line, a right-angled triangular arm (2) consisting of a horizontal member (3), a vertical member (4) and a brace (5) is placed on each of the columns (1). The vertical members (4) are supported by hinges (6) and (6) so as to be able to pivot on a horizontal plane, and a channel-shaped frame (8) is provided on each horizontal member (3) of these arms (2). The two elongated roller conveyors (7), (7), which rotatably support a number of rollers (9) therein, are parallel to each other at an interval and equidistant from the support (1). , Each of which is rotatably supported on a horizontal plane, whereby the arms (2)... And the elongated roller conveyor alone (7), Is formed with parallel motion link mechanism by 7). The conveyors (7), (7) are formed long by sequentially connecting conveyor shorts of a fixed length at the positions of the arms (2) by channel-like connecting plates (10) (see FIG. 1). 3, 4).

[0008] The rotatable shaft supporting structure on the conveyors (7), (2)... Of the (7) is as follows.
As shown in FIG. 4, a shaft with a head (11) penetrates through the center of the bottom plate of the channel-like connecting plate (10), and both upper and lower sides of a horizontal member (3) formed of a square pipe of the arm (2). Bearings (12) and (12) are fixed to the horizontal member (3), and the connecting plate (10) is placed on the horizontal member (3) with a washer (13) therebetween. 13) and the bearings (12), (12) are rotatably inserted and supported.
(14) is a retaining nut screwed onto the projecting lower end of the shaft (11).

[0009] The above-mentioned conveyer short unit is inserted into the groove of the connecting plate (10) mounted on the arm (2) in such a manner that the ends of the pair of short units to be connected are put together, They are connected to each other by fixing them to the connecting plate (10) with bolts (15), (15) and nuts.

The support columns (1) are provided at their lower ends with seat plates (17).
The child pillar (18) of the square pipe is slidably inserted into the main pillar (16) of the square pipe having
The fixing screw (19) screwed into the side wall of (6) is inserted into the child pillar (18).
In this embodiment, the child pillar (18) is attached to an appropriate holding metal fitting (2).
5) is held on the column (P) of the bench (F).

In this embodiment, devices for locking the conveyors (7) and (7) in an expanded state are provided at both front and rear ends of the conveyors (7) and (7), respectively. As shown in (1), one end of a stayer (21) is connected to a side surface of an intermediate portion of a horizontal member (3) of an arm (2) via a bracket (20), and a conveyor unit forming an angle with the arm (2). A locking plate (22) having a locking hole (23) protrudes from a corresponding side surface of the underframe (8) of (7), and the conveyor unit (7). The distal end is detachably locked to the locking hole (23) of the locking plate (22) with a lock pin (24),
The expansion state is locked.

Further, a spacing adjusting device for the conveyors (7) and (7) utilizing the locking device is provided, which is provided with a plurality of locking holes (2) in the locking plate (22).
3) Opening the conveyor unit (7) at an interval in the longitudinal direction, and locking the tip of the stay bar (21) in a desired locking hole (23) with a lock pin (24) to form the conveyor unit. The distance (d) between (7) and (7) can be changed and adjusted to a desired width.

The operation of the above example will now be described. Roller conveyors (7), (7) are moved in parallel and deployed, and both conveyors alone (7),
The intervals of (7) are set, and the stays (21) of each interval adjusting device are locked in the required locking holes (23) with the lock pins (24) corresponding to the intervals. Next, each pillar (1) ...
Is loosened to extend and contract the pillars (18) so that the conveyors (7) and (7) have a gentle downward slope from the transport source to the transport destination. When the seedling box and the like are placed on the conveyors (7) and (7) at the transportation source, they are transported while traveling on the conveyor.

After the transfer is completed, the lock pins (24) of the respective interval adjusting devices are removed, and then the conveyors (7), (7)
1 (b) and FIG. 2
Fold as shown in (b). Thereby, the whole conveyor is converged to a small width, and there is no hindrance to the next operation.

In another embodiment shown in FIG. 6, a conveyor alone (7
a) and (7a), the column (1a) ...
This is an example in which a) is fixed to the upper ends of the columns (1a)..., respectively, and the other structures are substantially the same as those in FIGS.

Further, the columns (1)..., (1a)... In the examples of FIGS.
And (Pa) of (Fa) are also used.

[0017]

According to the folding type conveyor of the present invention, when used, a plurality of conveyors are moved in parallel and developed to a usable state, and when not in use, the plurality of conveyors are brought into a narrow convergence state together with an arm. It can be folded so that the next operation can be performed without hindrance to wasting space in the working room.
