Abstract

PURPOSE:To pile a certain number of seeding boxes without suspending the piling work by installing a driving means for downwardly transferring the supporting part by a certain quantity by the turn of an endless turning belt. CONSTITUTION:A seeding box 1 sent to a piling work position by a transverse feeding mechanism 4 is piled onto the seeding box 1 in the supported state by the supporting part 6a of an endless turning belt 6b through an opening/ closing shelf mechanism 5. Further, the seeding boxes 1,... in the piled state are transferred to a loading part T by the turn of the endless turning part 6b after the piling quantity reaches a certain quantity. Further, the position of the supporting part 6a can be set at the position where the new piling operation can be started by the turn.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a seedling box stacking device.

[Conventional technology]

Conventionally, the following operations are required to obtain a tongue-shaped surface used for planting seedlings with a rice transplanter.

In other words, a seedling box with approximately the same dimensions as the mantle-shaped surface is supplied with a bed, seeds are sown, covered with soil, and watered.Then, the seedling box that has been sown in this way is placed at a predetermined humidity and temperature. They are allowed to germinate under certain conditions and are then allowed to grow and become green (references not listed).

[Problem that the invention seeks to solve]

Furthermore, since the above-mentioned seeding process has conventionally been carried out almost manually, it is desired to mechanize the work from seeding to greening and perform a large amount of processing.

Now, let's consider a case in which a device is automatically operated to stack a predetermined number of seedling boxes after sowing, or to stack a predetermined number of empty seedling boxes to store them. In this case, feeding the seedling boxes as continuously as possible increases work efficiency, but if the operation of the device is set to simply stack the seedling boxes that have been sent in, Every time the number reaches a predetermined number, the operation of the device must be stopped in order to take out the stacked seedling boxes.

The purpose of the present invention is to provide continuous feeding of seedling boxes without interrupting the supply, and without stopping the operation for stacking.
The object of the present invention is to obtain a seedling box stacking device capable of stacking a predetermined number of seedling boxes.

[Means for solving problems]

The features of the present invention include an endless rotating band that includes a support section that receives and supports seedling boxes in a stacked state and that rotates in the vertical direction, and an endless rotating belt that rotates vertically. By rotating the rotating band, the supporting section is moved downward by the thickness of the seedling raising box, and when the number of seedling growing boxes stacked and supported by the supporting section reaches a set number, an endless rotating band is formed below. and a driving means for moving the supporting part downward by a predetermined amount by rotation of an endless rotation band in order to transfer the stacked seedling growing boxes to the placing part, and its operation and effects are as follows. It is as follows.

[For production]

For example, if the features of the present invention are configured as shown in FIG.
The seedling raising box (1) sent out to the stacking work position by the transverse feed mechanism (4) is supported by the supporting part (6a) of the endless rotating belt (6b) via the opening/closing shelf mechanism (5). The seedling growing boxes (1) are stacked on top of the boxes (1), and when the stack reaches a predetermined number, the endless rotating section (6b) rotates to move the stacked seedling growing boxes (1) onto the mounting section (T). This rotation also allows the support portion (6a) to be positioned at a position where a new stacking operation can be started.

〔Effect of the invention〕

Therefore, instead of directly stacking the seedling boxes on the mounting section, by configuring the seedling boxes to be supported by a stepless rotation belt until a predetermined number of seedling boxes are stacked, for example, the stacked seedling boxes can be stacked from the mounting section. Even if it takes extra time to remove the
A seedling box stacking device was obtained that does not interrupt the continuous supply of seedling boxes or stop the operation for stacking.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

Figure 1 shows a seedling box stacking device that stacks seedling boxes after sowing.The seedling boxes (1), which have been fed on the floor, sown, watered, and covered with soil, are transported by a heald conveyor (2). It is fed into a stacking device.

As shown in the same figure and FIG. 2, the stacking device has a pair of locking pieces (3a) for locking the seedling boxes, which are arranged with the belt conveyor (2) in between. Endless band (3b), (3b) each with sprocket (3C)
, (3c), and an endless mechanism having projections (4a), (4a) for sending the seedling box (1) lifted by the lift mechanism (3) in a substantially horizontal direction. Connect the belt (4b) to the sprocket (4c), (4c
), and as shown in FIG. , a pair of swinging members (5a) that can be opened on both sides.

An opening/closing shelf mechanism (5) consisting of (5a) and this opening/closing shelf mechanism (
A pair of endless rotating belts (6b) each having two supporting parts (6a) that catch the seedling box (1) dropped and supplied by the opening operation of 5) and a sprocket (6c).

A stacking support mechanism (6) formed by winding around (6c) and a lid (7) and A deck (9) that supports a transportation trolley (8) is supported by the deck (9) during work, and is formed with an opening (18a) through which the lifter (7) is inserted. ) from the stacking support mechanism (6) against the seedling box (
1)... can be transferred.

In addition, the seedling box (1) sent by the belt conveyor (2)
A first sensor (Sl) is provided to detect when the seedling box (1) has reached a position where it can be lifted by the lift mechanism (3).
3) is activated by the first motor (Ml) that drives the lift mechanism (3) in order to move the locking piece (3a) upward by an equal stroke between the upper and lower portions of the locking piece (3a). A second sensor (S2) is provided to detect when the raised seedlings (1) lifted up by the cross-feeding mechanism (4) have reached a position where they can be transversely fed, and this second sensor (S2)
When it detects the seedling raising box (1), it operates the second motor (g) that drives the horizontal feeding mechanism (4), and the seedling raising box (1) sent by this horizontal feeding mechanism (4) moves to the stacking work position. A third sensor (S:l) is provided to detect that the seedling raising box (1) has been reached, and when the third sensor (S,) detects the seedling raising box (1), the swinging member (5a) of the opening/closing shelf mechanism (5), (5a) and the third motor (M3) linked via the link (5b), the opening/closing shelf mechanism (5) is operated to open and at the same time, the endless rotation band (6b) of the stacking support mechanism (6), (
The fourth motor (M4) that drives the stacking support mechanism (6) is actuated to move the opposite sides of the stacking support mechanism (6b) downward by the thickness of the seedling box (1). ) for detecting that the number of stacked seedling boxes (1) supported by A fifth sensor (S5) detects that the
), and when the fourth motor (M, ) enters the detection state, the fourth motor (M4) operates to move the seedling box (1)
The lid (7) that moves the... downwards is raised to a predetermined level, and this movement also causes the fifth sensor (S5) to move downward.
When the detection state is reached, the operation of the fourth motor (M4) is stopped, and at the same time, the fourth motor (M4) and the stacking support mechanism (6
) is once set to a braking state, and then the braking is released to lower the seedling growing box (1) by its own weight. Then, due to the lowering of its own weight, the seedling growing box (1) is stopped by the beam lid (7) and transferred to the transport cart (8) by the slow descent of the lifter (7).

Incidentally, when the transfer is performed in this way, the next support part (6a) reaches the upper part of the stacking support mechanism (6) at approximately the same time, and the stacking device continues to operate even when the transport cart (8) is replaced. is now possible.
