Abstract

PURPOSE:To transport odds and ends by arranging plural units where transport line materials reciprocating in the transport direction are arranged side by side in the direction perpendicularly to the transport direction, moving outward the line materials of the respective units in synchronization with each other, and returning same in plural times at high speed in a conveyer using inertia for a transported article. CONSTITUTION:All hydraulic cylinders 18, 18... are synchronously moved outward by a stroke S in the transport direction Z to synchronously move outward the transport line materials 11 - 13 of the respective units A - C, thereby moving a transported article. The line materials A-11, B-11, C-11 of the units A - C are taken as one set and synchronously returned at high speed. Subsequently, the line materials A-13, B-13, C-13 are returned in the same manner. At last, the line materials A-12, B-12, C-12 are returned. By this arrangement, on every return, a transported article is stopped at that place by inertia and finally the transport work is completed. Thus, miscellaneous articles can be transported and the transport width can be easily exchanged according to the size of a transported article.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a conveyor that transports objects in one direction, and in particular, a conveyor that utilizes the inertia of the transported object, and the width of the transport surface is adjusted. Concerning a conveyor with a unique structure that has excellent load capacity.

(Prior art) Conveyors that have been widely used in the past include a screw that rotates a spiral blade, and a belt conveyor that rotates a belt that is passed around spaced rollers. In addition, there is a chain conveyor that rotates a plurality of chains that are passed around spaced apart sprocket I-wheels. Depending on the purpose, for example, screws: ``Nhair is mainly used for transporting sand in Miki work, belt conveyors are used for long-distance transportation of granular materials such as to Pereno 1, intermediate products, and finished products in the factory. Chain conveyors are also used to transport relatively heavy packages surrounded by wooden crates, etc.

(Problem to be Solved by the Invention) Although the conveyor described above is suitable for transporting various small items and lightweight items, it is suitable for transporting heavy objects such as metal wires, rocks, and iron pieces. When transporting waste containing paper or wire materials, the bell and chain may become deformed or torn due to heavy objects.

In addition, spiral blades and chains can become tangled with wires and become sluggish in operation, so it is necessary to identify the items to be transferred to a certain degree. In addition, once the width has been manufactured, it is difficult to change the width, and the
Laws also had to be limited.

The present invention has been devised in view of the above, and enables the transfer of a wide range of solid materials, from granular materials to large heavy materials, including waste mixed with miscellaneous materials such as various heavy materials and wire rods.
It is also an object of the present invention to provide a conveyor with excellent load resistance, whose width can be easily changed depending on the size of the object to be transported.

(Means for Solving the Problems) A conveyor that achieves the above object moves transport strips supported on an abutment so that they can reciprocate in the transport direction, approaching each other in a direction orthogonal to the transport direction. A plurality of transfer units arranged side by side can be arranged side by side in the above-mentioned orthogonal direction, and the corresponding strips of each phase are connected at the lower part by a horizontal frame, and a reciprocating drive is provided to each horizontal frame. A means is provided to move all the reciprocating drive means forward a predetermined distance in the transportation direction in a synchronized state, and after the forward movement is completed, to make the return movement at a higher speed than during the forward movement for the specified distance, and It is constructed by providing a control means for repeating reciprocating motion.

A plurality of protrusions having an upright surface facing the direction of movement and forming a gentle slope toward the opposite side of the direction of movement are spaced apart in the longitudinal direction on the upper surface of each of the moving strips to further improve transfer efficiency. It is possible to take a configuration that improves the performance.

(Function) In the conveyor configured as described above, the plurality of transfer strips constituting one transfer unit 1 are each supported in close proximity to each other so as to be reciprocally movable on supports in the transportation direction. The corresponding transport strips of the transport UNISO I~, which are appropriately added according to the width of the object to be transported in the direction perpendicular to the transport direction, are connected at the lower part by a horizontal frame, and each horizontal The rods are reciprocated separately and simultaneously by reciprocating drive means provided for each rod. During transportation, the control means causes the reciprocating drive to move simultaneously by a predetermined distance in the transportation direction.
All of the transfer strips are moved forward, and the objects placed on them are transferred by a predetermined distance.

After that, the reciprocating drive means is divided into multiple times by the control means and is moved back at a higher speed than the forward movement speed, and the transport strip corresponding to each reciprocating drive means is moved back a predetermined distance via the horizontal frame. Then, the object to be transferred is returned from under the object, and all the transport strips are returned so that the object will not return from the position from which it was carried during forward movement due to the inertia of the object. By repeating the above two operations, the object to be transferred is intermittently transferred by a predetermined distance on the transfer strip. Therefore, even wastes including various heavy objects, wire rods, earth and sand, etc. can be easily transported, and a wide variety of solid materials can be transported.

The transport strip has erected surfaces facing the transport direction on 42 sides,
In addition, if a plurality of protrusions that form a gentle slope toward the opposite side of the transport direction are spaced apart in the longitudinal direction, the resistance during the return movement of the transport strip can be reduced, and the transport force can be increased with almost no return of the transported object. can be transmitted to the transferred object more reliably.

(Example) Examples will be described with reference to the drawings.

In FIGS. 1 to 3, the waste transport conveyor 1 is
The starting end of the transport is placed on the lower blade of the silo hopper 2, which is widened to prevent clogging due to bridging phenomenon, and extends almost horizontally toward processing equipment such as a crusher.
A transport system consisting of three transport rails, 42° 13, supported so as to be reciprocatable in the transport direction 2, arranged in parallel in a direction perpendicular to the transport direction Z and close to each other. Three sets of units Δ, 13°C are arranged in parallel in the above-mentioned orthogonal direction.

The support base 15 consists of a rail with an inversely convex cross section that is fixedly extended in the transportation direction Z on the pedestal 6, and has a transport stroke only where the drive rods 17 of the transport strips 11, 12, and 13 pass. - Interrupted for 98 minutes. It goes without saying that the drive rod 7 can be moved back and forth through the elongated hole without interruption. Transport strip], 1, 12
, 1.3 are slidably engaged on the abutment 15 with a lubricant such as grease interposed therebetween, and are durable with concave and convex engagement so that they can move relative to the adjacent ones on each side. Good sealing materials SL and S2 are installed.

The drive rod 17 erected on the horizontal rod 14 is connected to each transporting strip], 1. ], 2. ],
3, and is welded to the transport strip at the lower part of the side surface. It goes without saying that instead of welding, the parts can be removably connected and fixed using fasteners. The reciprocating drive means 18 has approximately 30 to 20 Oni
It is composed of high-output hydraulic cylinders with strokes 1 to S of n, and is connected to approximately the center of the horizontal rod 4. Moreover, it goes without saying that the connecting points can be changed or the number can be increased depending on the number of transfer units 1 to 1. Horizontal rod 1

In the configuration described above, the hydraulic control means (not shown) moves all the hydraulic cylinders 18, 18° 18 in the transport direction 2 in a synchronized state by the stroke 1-stroke S to move the transport strip material. 11, 12. Transfer the waste 0 on 13 [Figure 3 (a
) to Fig. 3(b)], after the forward movement is completed, the strips 11, 12, and 13 are moved back three times at a distance corresponding to the stroke S at a higher speed than during the forward movement. . That is, first, the first strip material 1 of each unit A, B, and C is placed on top.1. B-1
1° C-11 is returned to its original position by the high-speed double movement of the first hydraulic cylinder 18 [as shown in FIG. 3(c)], and the waste O remains on the other second and third strip members 12.13. ing. Then, the second strip material A-13. B-13゜C-13 was restored [3rd
As shown in Figure (d)], the waste material 0 has completely returned to the other second strip material 12 and remains on the stationary first strip material 1. Finally, by high-speed double movement of the second hydraulic cylinder 18, the third strip material A is

], the waste ○ will be transported from the solid line position to the dashed-dotted line position in FIG. 3(a).

By repeating the above operations, the waste ○ will be transported step by step.

Transfer strip 11. ．． As shown in FIG. can be set. Moreover, the reciprocating drive means 18 can be constructed by combining a motor and a Fick return cam mechanism instead of a hydraulic cylinder. When using a hydraulic cylinder, the transfer speed can be adjusted by appropriately arranging a limit switch to change its stroke length, or by adjusting the flow rate of hydraulic pressure. Furthermore, if the object to be transferred is powder or granular material, it goes without saying that an adapter such as a fall prevention plate can be appropriately provided on the transfer strip in order to prevent the object from spreading laterally and falling from the conveyor 1.
