○Example The following description will be made based on the embodiments shown in the drawings.

Referring to FIGS. 1 and 5, the conveyor A is a wide band-shaped flexible sheet (a soft synthetic resin sheet, a synthetic rubber sheet,
(rubber-coated canvas, etc.) 1 is fixed to both ends thereof, and the belts 2 are engaged with each other to maintain the tubular shape.

In the embodiment, a timing belt 3 having a protrusion 3a on the side opposite to the belts 2 and 2 and driven by a timing belt 3b was provided.

As shown in FIG. 18, the conveyance path 10 can be moved horizontally or vertically, and is curved in the horizontal direction.

It is capable of vertical curvature, that is, three-dimensional displacement, and uses the upward frontage P as the supply port and the downward opening Q as the discharge port.

R is the twisted part, as shown in Fig. 19, the belt 2.
．． By displacing the timing belt 3 from horizontal to vertical or from vertical to horizontal while being guided by drive rollers, guide rollers, etc., the conveying body A can be twisted at any angle and over any section.

Next, regarding the structure of the opening P-Q, see Figures 1 to 5.
This will be explained with reference to the figures.

The driving teeth 5a on the surface of the belts 2 and 2 are pressed together.
A pair of driving rollers 5 are provided at the front and rear of the opening P-Q, respectively, and the driving rollers 5 engage with the outside@4 provided on the outer surface of the belt 2 and move the belt 2 by rotation. A pair (or multiple pairs with an appropriate gap in the direction of travel) of idle rollers 6, 6 are provided in the center to slide on the inner surfaces of each of the belts 2, 2, and the belts 2, 2 are forcibly separated. Then, both belts are released and openings P and Q are formed. Note that in the opening P-Q, the drive roller 5
・A pair of drive rollers 5 and 5 are provided in front or behind 5,
One of the driving rollers 5, 5 on the side of the connecting section P-Q is set at a relatively lower position, and in the openings P, Q and the vicinity thereof, one side is set relative to the normal conveying section uniformity and the relative vertical position of the belt. The belt 2 is placed at a lower position compared to other healds 2. In addition, a part of the drive roller 5 that does not have drive teeth 5a is used, and only a guide mechanism is used to regulate the vertical position of the belt 2 and press the belts 2 in the direction in which they contact each other. It is also possible to have one.

The belt engaging mechanism B will be explained with reference to FIGS. 3 to 7.

The opposing surfaces 2b, 2b of the pair of belts 2, 2 are mutually flat, and the drive roller 5 meshes with the external teeth 4 of the protrusion provided on the outer surface side.
By this, the opposing surfaces of the belts 2, 2 are pressed into contact with each other, and the upper and lower surfaces of the belts 2, 2 are brought into contact by the engagement of the stepped portion 5a formed on the drive opening lug 5 with the lower surface 4a of the external teeth 4 of the belt 2. It is configured to regulate the position.

Therefore, by shifting the relative vertical positions of the pair of drive rollers 5, 5, the relative vertical positions of both belts 2, 2 are changed.

By changing the relative vertical position of both belts 2.
- A belt engagement mechanism B is provided that allows the second engagement state to be freely engaged and disengaged.

As the belt engagement mechanism B, an extended pleated portion 2a is formed at the upper end or lower end of the heald 2, and a locking protrusion or locking protrusion 7 is continuously or intermittently provided at the end of the extended pleated portion 2a. A locking surface 8 corresponding to the locking protrusion 7 is formed on the outer surface of the belt 2 (see FIGS. 6 and 7).

Alternatively, as shown in Figures N8 and 9, a locking protrusion 7', a recess 9, and a hole 9 may be formed on the opposing surface of the heald 2.

Further, as shown in FIGS. 10 to 13, the belts 2 can be forcibly engaged and separated by means of auxiliary means. That is, a rotatable lock piece 11 is provided in a recess 1o formed on the opposing surface of one belt 2, and a groove 12 that can be freely engaged with and disengaged from the lock piece 11 is provided in a recess 10' formed on the opposite surface of the other belt 2. By mechanically rotating the lock piece 11 at a predetermined position using a rotating means such as a lever, the lock piece 11 and the groove 12 are forcibly engaged and separated by mechanical means. .

Also, there is Velcro on the opposing sides of both tapes.

By attaching a member with a sealing effect, such as a fastener, it is possible to prevent leakage of conveyed objects during conveyance. It goes without saying that the objective effects of the present invention can also be achieved by changing the structure of the belt and providing external teeth or engaging portions directly or intermittently on the flexible sheet or fabric.

Next, the knot stopper will be explained.

The joint stopper C is shown in Figs. 14 to 16 as I! In contrast, a stop plate 13 having both ends fixed to one of the belts 2 and the timing belt 3, and a spring body 14 attached to the other belt 2 and the timing belt 3 are provided on the outside of the flexible sheet 1,
By joining and separating both belts 2 and 2, it is in working condition! ! ! (It is configured to change between the blocking state and the frontage state.

In the embodiment shown in FIG.
In the embodiment shown in FIG. 16, there are two partially circular strips connected by a hinge 15.

Referring to Fig. 17 S, the joint stopper C is in the frontage state (non-operating state) at the frontage portion P-Q and does not cause any trouble in feeding the conveyed object, but in the middle of the slow speed, the flexible sheet 1 is folded in two to form a blocking suspension (operating state), which prevents the conveyed object from falling during vertical conveyance or inclined conveyance, and conveys it smoothly.

O Effects of the Invention The first invention of the present application causes the belts to engage each other with drive rollers that engage with teeth on the belts at both ends of the flexible sheet, so that horizontal and vertical curvatures of the conveying body are avoided. It is possible to reliably maintain various complicated conveyance path configurations such as the following, and convey to an arbitrary position in three-dimensional directions.

The second invention of the present application uses a pair of drive rollers to maintain the flexible sheet in a tube state, and the rollers separate the belts from each other to open the belt, so that an opening of a desired length can be reliably formed at a desired position. can do.

Book il! In the third invention, since the tube-shaped conveyance path is divided at appropriate intervals by the joint stoppers, vertical and inclined conveyance can be carried out smoothly, and the joint stoppers can be set in the 3[operating state] at the frontage of the transport. This allows for the supply of conveyed objects and the tJF output without any problems.
