The present invention provides a mother mounting table which is installed in a state where the mother cutting blade is reciprocated up and down and driven, and the mother cutting blade that has been split is picked up by one follicle from the mother's thigh. In conjunction with the transfer motion of the mother seedling blade, the reciprocating sliding side of the base is installed freely, and the transfer device for vertically conveying the wool is provided on the back side of the mother mounting table. It relates to a model planting device.

In the former modeling apparatus, when the simulation longitudinal conveyance is not necessary, the conveying apparatus is stopped and frictional force is prevented from slipping to the mother supply port side of the mother mounting table using frictional force.

In this type of seedling planting device, conventionally, as shown in Japanese Patent Application Laid-Open No. 61-69924, it is placed in a place located between the mother longitudinal conveying member and the mother supply portion from the side of the mother placing table. The mother pressing member that presses the hair to the mother mounting surface of the mother mounting table is installed so that it can be switched freely to the lowering action position and the lifting action release position. The pressing member is switched to the lifting action release position, and when the hair is not conveyed, a mechanism for automatically switching the mother pressing member so that the mother pressing member is in the lowering operation position is provided. A small amount of hair dropped to the mother supply port side from the acting end of the mother conveying apparatus, and the stopper action by the mother longitudinal conveying member is reduced. Even if it could not be prevented, it was in that it was possible to prevent the pubic hair from slipping down due to the pressing action of the mother pressing member.

Conventionally, it is necessary to install the mother pressing member freely, and at the same time, it is necessary to install the switching operation mechanism of the mother pressing member. Was being done.

The object of the present invention is not only to prevent slipping, even if it is impossible to provide a small amount of wiping material placed on the bristle mounting surface and to prevent the wiping action against slipping by the bristle conveying device. Therefore, the present invention aims to provide a structure in which simulated longitudinal transfer failure does not occur.

The mother planting apparatus according to the present invention has a mother placing surface in which a plurality of non-slip protrusions are arranged at the bottom side of the substrate placed as described above in order to achieve the object, and are distributed in the transverse direction of the mother placing table. In addition, between the working end part of the mother conveying apparatus mentioned above and the mother supply part mentioned above from the side of a mother mounting table, and the 2nd located behind the hair | bristle of the 1st row of row | line | rows which are taken out by the said seedling blade. The anti-slip projections, which are arranged to act on the simulated pile hairs 12 of the row of the tenth row, are slipped and lowered to the side of the hair-feeding portions of the hair piles which have been placed in the driving stop state of the hair transfer device. To prevent movement of the loaded mother conveying device by the conveyance of the mother feeding device described above in the driving state of the mother feeding device described above. It is made. Preferably, it is proposed to make the installation intervals of the aforementioned non-slip protrusions larger than the center region of the parent mounting surface in both transverse directions of the mother mounting surface.

Actions and effects of the mother plant according to the present invention are as follows. The pubic hair becomes a small amount of hairs described above, preventing the slipping by the mother conveying device, and at the same time, simulation consumption in the first row of rows of pubic hair proceeds, and below the row of rows in the second row. In the case where a simulation member is created, the anti-slip projection is held in the second row of the simulation row, and the simulation longitudinal conveyance is not carried out, the supporting force by the locking of the anti-slip projection becomes greater than the weight loss force of the wit During the vertical conveyance, the vertical conveying force of the simulated longitudinal conveying member and the simulated longitudinal conveying force due to the weight of the embroidery become larger than the support force of the non-slip protrusion, and the latter is slid to the mother supply port side. The movement is made possible by setting the action force of the anti-slip protrusion.

In addition, by increasing the installation interval of the non-slip protrusion as much as the center region, it is possible to prevent slipping in a stable state without giving a longitudinal transfer resistance that is greater than necessary for wiping.

The non-slip projection at the place of the mother mounting surface is preferably set so that the installation distance is set to be as large as the center area, so that deformations during simulation and vertical conveyance cannot be generated by a simple method. This is to prevent the small amount of wit from slipping down and to prevent the hair from slipping down. Not only can the work be performed in a state where no defects occur, but it can also be obtained cheaply in terms of structure or manufacturing process compared to the conventional one.

Even if a small amount of hair located between the ends of the carrier belt 51 prevents the slip support, and as indicated by the imaginary line in FIG. 9, the parent member portion is placed below the second row of rows B as shown in FIG. Even if the holding | maintenance by the mother stopper part 8a of the mother mounting base guide 8 disappears, a mounting pot A 12 is considered to be prevented from falling into the slip mode supply (13).

That is, the anti-slip projection 27 is located between the end of the actuation end of the mother conveyance belt 51 and the mother supply portion 13, as viewed from the side of the mother mounting table, and the second row of rows of the mounting port hair 12 ( It is considered to stop from below in B). Then, as shown in FIG. 10, the anti-slip protrusion 27 is formed to have a triangular shape when viewed from the side of the mother mounting table, and the thickness T, the height H and the non-slip protrusion 27 are formed. The bottom length W is formed such that T = about 1.2mm, H = about 4mm, W = about 4mm, etc. When the conveyance is not carried out, the holding force by the locking of all the non-slip protrusions 27 becomes larger than the self-lowering force of the small amount of hair described above, so that the anti-slip protrusions 27 do not cause the mounting port head 12 to slip. When the vertical conveyance of the mounting port 12 is carried out, the longitudinal conveyance action by the longitudinal conveyance belt 17 and the mother longitudinal conveyance force by the weight of the small amount of hair are applied to the latches of all the anti-slip projections 27. It becomes larger than the holding force by the non-slip protrusion 27, and the anti-slip projection 27 It is configured to enable longitudinal conveyance movement.

In addition, since the non-slip projection 27 has a larger base length W than the thickness T, the locking action 27 is configured so that the locking action can be effectively performed to prevent even the staggering operation in the lateral width direction of the placement port hair 12. have.

As can be seen from FIG. 9, the anti-slip projection 27 is arranged in a state in which the excretion density at both ends in the transverse direction of the parent mounting surface is larger than the excretion density at the center in the transverse direction of the mother mounting surface. It is.

That is, in view of the non-slip projection 27, the mounting port hair 12 starts to slide off from the transverse end, so that the anti-slip locking action at the transverse end is performed in the transverse direction. It is larger than the anti-slip locking action at the center, and is considered to effectively prevent slipping while preventing the total conveyance resistance from being excessively increased.

In addition, the hair growth of the pot hair used in description of this Example is demonstrated here.
