Abstract

PURPOSE:To apply moderate tensile force to tapes to be cut and improve cutting performance by providing a nipping mechanism for nipping the tip side from a position to be cut of continuous tape provided with plural stocks of blocklike seedlings to a part for cutting and separating the tape seedlings. CONSTITUTION:Tape seedlings are intermittently fed by a rotating belt 3 installed in the vertical directions and a plating arm (6a) having an integrally formed cutting blade unit 7 holds and plants the block seedling (a) nearly simultaneously with the cutting. The frontal sides of the tapes 1 and 2 from a position to be cut are pressed by pressing arms 20 between the receiving rollers 19 only synchronously with cutting to hold down a rodlike member 23 with a pressing roller 22 and separate the receiving roller 19 from the tapes 1 and 2. Thereby, the cut blocklike seedlings (a) are attained in a free state.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for attaching a plurality of block-shaped seedlings attached to a continuous tape at predetermined intervals and conveyed to the tape by cutting the tape. Regarding the tape seedling transplanter, which is equipped with a cutting mechanism that separates one plant at a time and a planting mechanism that plants the separated tape seedlings, By separating the continuous tape and planting the tape to which the shaped seedlings are attached, the block-shaped seedlings can be planted in one row, compared to the case where multiple grown seedlings are planted in one row with the continuous tape attached. The present invention relates to a tape seedling transplanter which has the advantage of being able to arbitrarily set the planting pitch without being tied to the tape attachment pitch.

[Conventional technology]

Conventionally, in this type of tape seedling transplanter, in order to cut and separate the tape holding one plant's worth of block-shaped seedlings, a pair of upper and lower receiving blades is used, with the tip side free from the planned cutting position of the tape. The body was cut with the cutting blade.

[Problem to be solved by the invention]

However, in this case, the leading end of the continuous tape, which is fed out to a position preceding the cutting site of the receiving blade and cutting blade, is in a free state and therefore remains hanging down. therefore,
There were times when the tape did not cut properly.

An object of the present invention is to provide a tape that can improve cutting performance by rationally processing the leading end side of a continuous tape.

[Means to solve the problem]

The characteristic configuration of the present invention is that a clamping mechanism is provided at the cutting part n of the tape seedlings to clamp the tip side from the planned cutting position of the continuous tape to which the plurality of block-shaped seedlings are attached, and its operation. The effects are as follows.

[For production]

In other words, by pinching the continuous tape, which is conventionally in a free state, at the tip end of the point where it is scheduled to be cut, an appropriate tension force can be applied to the tape to be cut, and cutting performance can be improved.

〔Effect of the invention〕

Therefore, cutting defects can be suppressed as much as possible, and reductions in work efficiency and planting defects such as missing plants can be avoided.

〔Example〕

A tape seedling transplanter for transplanting strawberry seedlings or rye seedlings as tape seedlings will be explained. This tape seedling should be prepared in advance.
A plurality of block-shaped seedlings (a) are sandwiched at desired intervals using continuous tapes (1) and (2), and the seedlings are folded and stored in a storage case (not shown).

The tape seedling transplanter is equipped with a rotary belt (3) that conveys tape seedlings fed from a storage case (not shown) to the cutting site, and is installed opposite the conveying surface of this rotary belt (3). Guide plate (4) and second tape (2) at the tape cutting site
A tape cutting mechanism (8) consisting of a receiving blade body (5) that receives the tape from below and a cutting blade body (7) formed on a planting arm (6a) as a planting mechanism (6) to be described later. , and a planting arm (6a) that holds and plants cut block-shaped seedlings (a).

The continuous tapes (1) and (2) are paper tapes,
This is done in consideration of cutting performance, and an adhesive is applied to the first tape (1) on the side closer to the cutting blade (7).

Therefore, since the cutting blade (7) acts to cut from the back (top) side that is not coated with adhesive, the first tape (1) is attached to the cutting blade (7) via the adhesive. There is no such thing as lifting.

In addition, since the first tape (1) is soft and the second tape (2) is hard, even after the soft first tape (1) is cut, the second tape is still hard. Because of its strong back, it is easily cut off even when it is alone.

As shown in FIGS. 1 and 2, the rotating belt (3)
is installed vertically, and the one-way clutch (11) is connected to the lower drive pulley (3A) from the feed case (10).
Power is introduced through the The feed case (1
A drive arm (12) that rotates continuously is pivotally supported on the drive arm (12), and a driven arm (13) that is driven to swing intermittently by contact with the drive arm (12), and a shaft of this driven arm (13). An arm (14) that swings integrally with the rotating belt (3) and a one-way clutch drive arm (16) that is connected to this arm (14) via a connecting rod (15) are provided. This constitutes a drive link mechanism.

Therefore, the tape seedlings are fed intermittently by the rotating belt (3). This rotary belt (3) has a plurality of conveying protrusions (3a) formed at equal intervals in the rotational direction, and the pitch (P) is the same as the clamping pitch (P') of the block-shaped seedlings (a) of the tape seedlings. Since the pitch is set at a certain pitch, the channel projections (3a) are positioned between adjacent block-shaped seedlings (a) and can perform a reliable feeding action.

A planting case (17) is extended from the feed case (10) in a cantilevered manner, and this planting case (17)
A planting arm (6a) type planting mechanism (6) is pivotally supported on the tip side, and reciprocates and circulates between the planting surface and the planting surface in order to hold and plant the cut block-shaped seedlings (a). Moreover, a cutting blade (7) is integrally formed on this planting arm (6a),
The planting arm (6a) cuts the block-shaped seedling (a) almost simultaneously with cutting.
) is held and planted at the tip of the planting arm (6a).

The clamping mechanism (9) that clamps the tapes (1) and (2) on the tip side from the intended cutting position will be explained. This clamping mechanism (9) has a swinging arm (1) that applies the tape (2) from below.
8) Consists of a receiving roller (19) at the tip and a presser arm (20) that presses from above, one receiving roller (19) is always urged upward by a spring (21), and the other presser arm ( 20) is intermittently driven in conjunction with a drive arm (27) and a connecting rod (28) which are fixed to the pivot arm (13).

Therefore, only when cutting, the presser arm (20) is designed to press the tip side of the tapes (1) and (2) from the intended cutting position. In addition, a rod-shaped member (23) extends from the tip of the swing arm (18) toward the planting arm (6a), and a presser roller (
22) and the planting arm (6a) rotates to cut the tapes (1) and (2).
) to press down the rod-shaped member (23) and release the receiving roller (19).
) is separated from the tapes (1) and (2), and the cut block-shaped seedlings (a) are left in a free state, and the planting arm (6a)
It is structured so that it can be held and planted well.

A stopper (2) is provided near the blade receiving body (5) to prevent the next block-shaped seedling (a) located subsequent to the block-shaped seedling (a) to be cut from being excessively fed out toward the cutting site.
4), and this stopper (24) is movable up and down and operates in synchronization with a bell crank (25) that abuts from below.

Moreover, this bell crank (25) is linked to the planting arm (6a) of the planting mechanism (6) by a connecting rod (26),
During cutting, push the stopper (24) upward to prevent subsequent seedlings from moving toward the cutting site.

[Separate actual precedent]

■ The tape (1) is a single piece, and the block-shaped seedling (a)
It is also possible to adopt a configuration in which the tape (1) is attached to the tape (1).

(2) As the cutting mechanism (8), a cutting blade (7) may be provided separately from the planting arm (6a).

■ The clamping mechanism (9) may be an integral scissor-shaped mechanism, and is not limited to the one shown.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
