Abstract

PROBLEM TO BE SOLVED: To provide a pot gripper, which is remarkably reduced in weight so that a person can easily handle it with a simple structure, and can easily transfer only one layer of seedling pots from a seedling pot laminate, in which seedling pots are stacked, to a seedling tray while keeping the aligned state of the seedling pots.SOLUTION: The pot gripper includes: a seedling tray placed downward; and a grip body 5 disposed on a portion having no side wall frame of the seedling tray with a pair of flexible and light holding plates 2 being biased in contact with the seedling pot side, the grip body including antislip members 3 installed on the side contacting the seedling pots of the holding plates. The grip body 5 is placed downward on the seedling tray and pressed onto the seedling pot laminate together with the seedling tray. Thereafter, seedling pots of one layer stored and held by the pot gripper are lifted up; one set of the grip body 5, the seedling tray and the seedling pots, is placed in position so that the opening sides of the seedling pots are upside; and the seedling tray storing the seedling pots is then separated from the grip body 5.

Description

  The present invention relates to a pot gripper configured to store a seedling pot of only one layer in a seedling tray in an arrayed state from a stacked seedling pot laminated body arranged vertically and horizontally, and a grip body used in the pot gripper .

  For example, Patent Literature 1 to Patent Literature 5 propose a pot gripper that accommodates only one layer of seedling pots in a seedling tray in an arrayed state from seedling pot stacks that are arranged vertically and horizontally. There is something.

  In any of the documents described above, the seedling tray placed in another place is held from the opening side of the seedling pot, with only the uppermost layer of the stacked seedling pots being spread out. Each seedling pot is dropped by the separating means in a state of being placed on the top of the container so as to enter each accommodating portion.

  However, in this method, the configuration of the pot gripper is to support a plurality of holders that enter the inside of the opening side of the seedling pot to hold the seedling pot, and that the holder is arranged in accordance with the arranged seedling pots. Support plate, separation means for each holding tool, and separation support plate for supporting these separation means in the same manner, and the entire configuration has to be complicated in two stages. .

  Therefore, the applicant of the present application uses a method different from the above, with a simpler configuration, and similarly, from the stacked seedling pot laminate, only one seedling pot is accommodated in the seedling tray in the arrangement state. Researched and prototyped whether a pot gripper could be made.

  1A and 1B show an example of a grip body of the present invention, in which FIG. 1A is an external perspective view thereof, FIG. 1B is a top view thereof, and FIG. 1C is a side view of FIG.

  The grip body 5 shown in FIG. 1 has a bottom portion cut out from a seedling tray in which square pot receiving portions 5a that are generally available on the market are arranged vertically and horizontally, and the inside of a side wall frame 5e provided at the central portion of each side. The holding member 2 is a pair of opposing members, and a non-slip member 3 is attached to the inside of the portion near the bottom of the holding member 2, and the holding member 2 facing the outermost end of the holding member 2 is mutually connected. The elastic means 4 (in this example, it is a rubber band, but it is not limited to this) which exhibits the urging | biasing force to attract is provided.

  The grip body 5 has the same configuration as that of a general seedling tray except for the above-described feature points. In addition to the above, a pair of longitudinal frames 5b that form the uppermost outer shape and a pair of perpendicular frames 5b that are orthogonal to the longitudinal frames 5b. A transverse frame 5c and an intermediate frame 5d forming each housing portion are provided.

  This grip body 5 removes the bottom of an established seedling raising tray, uses the side wall frame 5e provided at the center of each side as a holding member 2, gives the urging force by the elastic means 4, and the anti-slip member 3 As will be described below, it is urged to contact the side wall near the bottom of each seedling tray from between the side wall frames of the seedling tray to be accommodated.

In addition, this grip body 5 is a prototype configured to lighten unnecessary processing for a test and achieve an initial purpose, and as described later, the product exhibits its function. A combination of only what is necessary to do is suitable.

  Further, as a material of the anti-slip member 3, as described in Patent Document 2, “a bowl-shaped member in which fine irregularities are densely formed on the surface of a flexible sheet body” or paper Files, cloth files (so-called sandpaper), Darth Bond (registered trademark, made by Nippon Darth Bond Co., Ltd.), nylon non-woven fabric with hard particles, anti-slip rubber sheet, It may be slip-stained made of synthetic resin that lays on a trunk or the like to stop the movement of the load. In short, anything having a non-slip function is suitable.

  FIG. 3 is an external perspective view showing a state in which the seedling tray of FIG. 2 is placed on the grip body of FIG. 1, and both of them constitute the pot gripper 10 of the present invention. In addition, the part already demonstrated from this is attached | subjected the same code | symbol, and duplication description is abbreviate | omitted.

  As can be seen from this figure, since the seedling tray 1 has the side wall frame 1e at the corner portion, there is nothing at the side portion, and the holding material 2 provided with the anti-slip member 3 of the grip body 5 is provided here. Is urged by the elastic means (rubber rubber) 4 so as to approach the opposing holding member 2, so that the anti-slip member 3 is urged against the side wall of the seedling pot P accommodated in the accommodating portion 1 a of the seedling tray 1. Touch.

  FIG. 4 is a front view showing a state in which the combination of the grip body and the seedling tray shown in FIGS. 1 and 2 is fitted to the bottom side of the seedling pot laminated body arranged and laminated with the opening side down. One of the features of the present invention is that the seedling pot laminate PM is laminated with its opening facing down. In the lowermost layer, the seedling tray 1 is placed on the table B with the opening side down, and the seedling pots of the seedling pot stack PM are received by the outer portions of the storage units.

  FIG. 5A is a front view showing a state in which a combination of a grip body and a seedling tray is pushed into the bottom side of the seedling pot laminate from the state of FIG. 4, and FIG. It is sectional drawing.

  At this time, as shown in FIG. 5 (b), since there is no side wall portion of each accommodating portion 1a of the seedling tray 1, the holding member 2 provided with the anti-slip member 3 of the grip body 5 there is elastic means. In the state of being urged at 4, the portion close to the bottom of the side wall of the seedling pot P is brought into contact. At the contact portion, there is an anti-slip member 3, and by the anti-slip member 3 biased to come into contact with the seedling pot, only the seedling pot P of the uppermost layer of the seedling pot laminate PM is the pot gripper. Lifts up with 10.

  FIG. 6 is a front view showing a state where the grip body and the seedling tray are lifted together with the seedling pot of only one layer. The experiment was repeated many times, but in general, all the seedling pots arranged could be lifted only by one layer.

  FIG. 7 is a front view showing a state in which the seedling tray and the grip body in which one layer of seedling pot is accommodated are in the posture in which the opening side is up. In order from the top, a single seedling pot P, a seedling tray 1 and a grip body 5 are stacked in three layers and placed at another position on the table B.

  FIG. 8 is a front view showing a state in which a seedling tray containing a single seedling pot is separated from the grip body. The force with which the anti-slip member 3 of the grip body 5 holds the seedling pot is such that the seedling pot P does not fall in an upside down state, and the seedling pot accommodated in the seedling tray 1 against the holding force P can be reliably separated.

  FIG. 9 is an external perspective view showing the seedling pot in a state where only one layer is separated and accommodated in the seedling tray. Next, the seedling pots P separated by one layer and accommodated in the seedling tray 1 may be sequentially stacked on top of each other or passed to the next step.

  Thus, according to the pot gripper 10 of the present invention, the seedling tray 1 that is placed face down to accommodate the seedling pot P in the topmost seedling pot P of the seedling pot laminate PM, and the side wall frame of the seedling tray 1 A pair of holding plates 3 that are flexible and lightly urged to contact the seedling pot on the side of the seedling pot, and are arranged on the side of the holding plate 2 that contacts the seedling pot P. A grip body 5 having a member 3, the grip body 5 is placed downward on the seedling tray 1, and the grip body 5 and the seedling tray 1 are both pressed against the seedling pot laminate PM, and then the pot The gripper 10 is lifted together with the seedling pot P for one layer accommodated and held by the anti-slip member 3 of the grip body 5, and the grip body 5, seedling tray 1, seedling pot Is placed in a proper position so that the opening side of the seedling pot P is on the upper side, and then the seedling tray 1 containing the seedling pot is separated from the grip body 5, thereby completely different from the conventional method. Thus, the weight of handling by a person with a simple configuration is much lighter and easier, and from the stacked seedling pot laminate, only one seedling pot can be accommodated in the seedling tray in its arrayed state.

  Further, the gripper body 5 of the present invention has the same configuration as the grip body 5 included in the pot gripper 10, and exhibits the effect of the pot gripper 10 as the gripper body 5 when combined with the seedling raising tray 1.

In addition, the pot gripper of the present invention presses the non-slip material against the side wall or the corner side wall near the bottom of the seedling pot with an appropriate force and falls from the pot gripper as compared with the technique of opening the open side of the conventional seedling pot. There is a feature in that it is not, and it is completely different from the conventional technique in that it is lightly pressed from the outside to the inside in contrast to the one that spreads from the inside to the outside.

Moreover, since the seedling tray which should accommodate a seedling pot was used as a component part of a pot gripper, the structure of a gripper body is very simple and light as shown in FIGS. 12 and 13. Also, it will be cheaper.

In addition, when the seedling pots are stacked with the opening side down, the spacing between the bottoms of each seedling pot is less widened as it goes up, compared to the case where the bottom part is registered below, When putting a seedling tray in the uppermost seedling pot, it can be put in without problems.
