Description

[Detailed Description of the Invention] The present invention relates to the extrusion of a surface cocooned within the lattice-like sections of lattice-shaped waves [J structure].

In the conventional cocooning mechanism for cocooning the faces in the lattice-shaped group, the one that pushes out the faces at once and falls using the extrusion protrusions provided in the same number as the number of compartments in the first group, keeps the group in a predetermined position. A regulatory framework is required to regulate the number of groups, and therefore the attachment and removal of each group must be done manually.
The disadvantage is that it requires a lot of effort and time.

In addition, a method in which the number of extrusion protrusions is the same as the number of sections in one row, and the surface is collected sequentially every 1 j while sending the group by another mechanism, not only has a complicated mechanism, but also has a complicated mechanism for extruding the surface and feeding the basket. The drawbacks are that synchronization is difficult and the cocoon collection speed is slow.

Furthermore, the extrusion projections are attached radially to the rotating shaft, and the extrusion projections are rotated to feed the group and extrude the surface at the same time.
Considering the dimensions of the compartment, if the length of the extrusion protrusion is set to an appropriate length for smooth feeding of the basket, the insertion length into the compartment may be insufficient, and the cocoon once extruded will be re-divided due to the elasticity of the fluff. In order to prevent this, it is necessary to take measures to prevent the extruded surface from returning; however, as soon as the extruded protrusion is inserted the deepest, it draws a circular trajectory and is pulled out from within the compartment. Since the mechanism to prevent the reversal must be configured to separate the surfaces in the vertical direction, it is subject to various structural constraints, and it is difficult to remove the large and small surfaces from the compartment without damaging them at all. That is very difficult.

The present invention completely eliminates the drawbacks of the cocoon extrusion mechanism in the conventional cocoon storage mechanism described above, and is configured to send a lattice wave by the extrusion projections on the surface, and also pushes out the surface by the extrusion projections. State 11 can be moved by an appropriate distance, so that a structure for preventing the surface from returning can be easily realized.

The present invention will be explained in detail based on examples as follows.

Reference numeral 1 denotes a flat endless track constituted by flexible joints 2.

The flexible link 2 may be a belt or the like other than the chain shown in the figure.

In addition to the sprocket 3 shown in the figure, the member for constructing the flat endless track 1 by the flexible joint 2 may also be a belt pulley, a roller, or the like.

In any case, the specific configuration is free as long as the flexible joints 2 constitute the flat endless track 1.

Reference numeral 4 denotes a lattice-shaped wave forming vertical and horizontal lattice-like sections 5, and numeral 6 denotes a housing consisting of a group of 7 extruded protrusions corresponding to one row of the sections 5 of the lattice-shaped wave 4. The bodies 6 are arranged in rows on the outside of the endless track 1 in correspondence with adjacent rows of the sections 5 of the lattice wave 4.

In the figure, reference numeral 8 is a motor for driving the endless track 1, and 9 is a drive shaft for the endless track 1, but it goes without saying that any other mechanism may be applied to drive the endless track 1. .

In this configuration, when the lattice wave 4 to be collected is placed at a predetermined position and the endless track 1 is driven counterclockwise in the figure,
The endless track 1 allows the extrusion protrusion 7 of the housing 6 to be inserted into the lattice section 5 of the lattice wave 4 at one direction change part A,
After being linearly moved in one flat part B, it is extracted from the compartment 5 in the other direction changing part A', and then circulated again to one direction changing part A.

Thus, by inserting the extruded projection 7 into the compartment 5,
The cocoon 10 that has been laid is pushed out and moved along the flat part B while maintaining this state, thereby moving the lattice wave 4 to the right in the figure.

As the lattice wave 4 moves in this way, the extrusion protrusions 7 of the cocoon 6 that have reached the direction changing part A are sequentially inserted into the adjacent compartments 5, and while pushing out the cocoon 10 in the same way, the lattice Send shape wave 4.

In the present invention, in this way, the cocoons 10 in the compartment 5 are pushed out by the extrusion protrusion 7 in each row in the grid pattern, and furthermore, in the pushed out state, they move an appropriate distance in the lateral direction together with the grid wave 4, so that the cocoons 10 in the compartment 5 The cocoon separating mechanism for cutting the fluff 11 and separating the cocoons 10 can be constructed within such a moving distance, and must always be configured to separate the surfaces in the vertical direction.The above-mentioned conventional extrusion mechanism It has a greater degree of freedom in configuration and can be easily implemented compared to the conventional method.

In the figure, the cocoon separation mechanism is shown as having a comb-shaped partition separator 12 inclined with the direction in which the lattice wave 4 moves downward, and as described above, in the extruded state. The cocoon 10 moving laterally is separated from the fractional separation body 12.
Although a mechanism for separating is shown, this configuration is merely an example, and the specific configuration is free, such as providing a separating body in the shape of a thin rod or plate.

Reference numeral 13 in the figure is a means for restricting the endless track 1 in the flat part B, and by such appropriate cocoon/restricting means 13, the endless track 1 in the flat part B is made to be convex downward. This makes it possible to lengthen the insertion length of the extrusion projection 7 into the compartment 5, that is, it is possible to extrude the cocoon 10 and to better separate the surfaces by the cocoon separation mechanism. is not necessarily required.

As described above, in the present invention, a housing body consisting of extruded protrusions corresponding to one row of lattice-shaped sections of lattice-shaped waves is arranged on the outside of a flat endless track constituted by flexible joints, and the extruded protrusions The structure is configured so that lattice waves are sent by the extrusion projections, so that the surface can be extruded rapidly and continuously, and the surface can be moved an appropriate distance by the extrusion protrusions, so that the surface can be moved from the section to the surface. The main feature is that there is a degree of freedom in the configuration and installation position of the cocoon separation mechanism for separating the cocoons, and the purpose can be achieved with a simple configuration, making it possible to perform the cocoon collection work of lattice waves much more efficiently. has.
