Abstract

PURPOSE:To align a cylindrical material for moving it downstream by providing locking plates in an angle form symmetrically with regard to a carrier traveling line, and bringing the cylindrical material into contact with the locking plates. CONSTITUTION:A pair of plate-shape locking plates 3 are journaled to fulcrums 4 in an angle form symmetrically with regard to the traveling line of a conveyer 2 with their insides facing to downstream. Besides, a photoelectric switch 5 is installed at the entrance part of the locking plates 3, the passage of a material 1 is detected to drive a drive device, a pair of locking plates 3 which are located at a fixed position are oscillated synchronously to stop them in an angle form and are oscillated again in a few seconds to be returned to the fixed position. It is thus possible to transfer the material 1 stably and uniformly in the orthogonal direction to the conveyance direction to move it downstream even if the material 1 is carried with its core and direction being deflected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centering means necessary for folding a columnar material which is conveyed in an indefinite orientation which is different in length or not aligned from the center in the longitudinal direction in a post process. Regarding

[0002]

2. Description of the Related Art The prior art relating to the present invention is, for example, Japanese Utility Model No. 3-2513.
There is. This is to make the centering device for preventing the falling of the articles on the conveyor swingable, and to prevent the articles from being damaged due to the traffic jam on the conveyor. As another conventional technique, there is a utility model 2-83780. This is to align the dough by raising and lowering a dogleg-shaped stopper on a conveyor that vibrates vertically. In addition, as another conventional technology, there is one such as the actual Kaihei 3-44114, which uses a mechanical switch or photoelectric switch to determine the center of the cylindrical material and then horizontally aligns it downstream with a moving conveyor. Is going.

[0003]

The present invention is different from these and can be carried out by an easy method. A pair of cylindrical fabrics conveyed in an indefinite direction are symmetrically provided on the traveling line of the conveyor. The material is brought into contact with the locking member and is moved along the locking member while rolling and rotating the dough so that the running line of the conveyor is aligned with the center of the dough in the longitudinal direction. Even if the orientation of the cylindrical dough to be used is uncertain or the dough having different diameters and lengths is conveyed, it can be easily aligned and transferred downstream.

[0004]

The present invention will be described based on an embodiment. A conveyor 2 that conveys a cylindrical dough 1 is prepared. A pair of locking plates 3 are symmetrically provided along the traveling line of the conveyor 2 so as to be swingable on the conveying surface of the conveyor 2. The locking plate 3 is a pair of plate-shaped members, and a fulcrum 4 is formed so that the locking plate 3 can be formed in a V shape symmetrically with the traveling line of the conveyor 2 so that the inside faces downstream.
Is supported by. The locking plate 3 is normally stopped at a position where the passage of the material 1 is not blocked and fixed there, and can be swung around the fulcrum 4 to form a V shape. The angle of the C-shape is given as an optimum angle based on the properties, shape, size, etc. of the cloth. The swinging motion of the locking plate 3 is performed by a driving device (not shown). The operation timing of the drive device is as follows. Lock plate 3
The photoelectric switch 5 is provided at the entrance of the
When it detects that the cloth 1 has passed through, the drive device is activated, and the pair of locking plates 3 that have been in a fixed position are oscillated in synchronization to form a V-shape and stop, and then again within a few seconds. It swings to return to the home position.

In another embodiment of the locking member, a locking roller 6 is rotatably provided as shown in FIGS. The roller 6 is forcibly rotated by a motor (not shown).

[0006]

Next, the aligning function of the present invention will be described. The columnar material 1 to be conveyed is adjusted regardless of the difference in length or diameter of the material, and when the direction of conveyance or the position in the width direction is not constant, the direction and center position are adjusted and aligned. Then, it can be transferred downstream. The cloth 1 conveyed with the core or the direction displaced is brought into contact with the locking plate 3. The cloth rotates with the belt 21 at the locking position, but when the contacting positions of the locking plates are unbalanced as shown in FIG. The portion A touching the outer side moves to the inner side, and the portion B touching the inner side moves to the outer side, and is stably balanced in a state perpendicular to the transport direction. (FIG. 4) Subsequently, when the locking plate 3 swings and returns to the fixed position to release the material, the material is transferred to the downstream in the aligned state. Further, in the present embodiment, the locking plate 3 swings in the horizontal direction to achieve the object of the present invention, but the present invention is not limited to this, and the same effect can be obtained by the ascending / descending operation.

The operation of the locking roller 6 of the second embodiment will be described. When the locking roller 6 is forcibly rotated, the abutting cloth 1 is also forcibly contact-rotated, and its centering action is promoted. , Alignment is performed in a shorter time.

As described above, it is possible to align and align the columnar material that is conveyed by the simple mechanism and transfer it to the downstream. The present invention can easily perform centering even if the direction and position of conveyance of a cylindrical fabric are indefinite, or even when the fabric of different diameter or length is conveyed, and its application range is wide.
