Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a conveying device for conveying powder, solid, and plastic materials, such as earth and sand, ore, and drinks, almost vertically.

Conventional technology Conventionally, as a conveyance device in the loading direction, Japanese Patent Application Laid-Open No. 58-15
As shown in Figures 3 and 4 of Publication No. 2707, the four corners of a box-shaped packet are connected to four endless chains stretched through wheels, and these endless chains are driven synchronously. This allows each packet to be oriented upwardly in both the horizontal and vertical paths, allowing it to be transported as desired.

Problems to be Solved by the Invention According to the conventional method described above, the number of threads of the endless chain is large, for example four, which complicates the splicing process and increases the size of the equipment. In order to do this, timing alignment, adjustment of the four points in the chain, and drive control are complicated.

Means for Solving the Problems In order to solve the above-mentioned problems, the conveying device of the present invention has a pair of left and right endless rotating bodies stretched out to create a vertical path and a lateral path, and a conveyor between these endless rotating bodies. The front sides of the trays are swingably attached at predetermined pitches, and a guided body is accommodated in each tray, and a guide body that guides the drum guide body is arranged along a vertical path. A telescoping hanger is provided between the tray and the endless rotating bodies to extend to a maximum extent in the vertical path and hold the tray in a horizontal position, and a support guide device is provided to guide the tray in the horizontal path.

According to the configuration of the present invention, a moving force is applied to each tray by a pair (two threads) of endless rotating bodies on the left and right sides, and in the vertical path, the tray is moved by the guided body (because it is guided by the guide body). Shaking is prevented, and the υ horizontal posture is maintained by the telescoping hanging tool that has been extended to the maximum.Also, in the horizontal path, as the extending!1M tool contracts, the tray swings relative to the endless rotating body, and Since the tray is received by the support and guide device, a horizontal position is maintained.

5! EXAMPLE A -*X example of the present invention will be explained below based on the drawings. (
1) is a rectangular duct-shaped machine frame, with a common first
A pair of left and right first sleeve bodies (kumirin) (3
) is arranged, and a pair of left and right second wheels (5) are arranged at the lower rear end via a common second rotation shaft (4). A pair of left and right third wheels (7) are disposed slightly above the second rotation axis (6) via a common third rotation axis (6), and a cantilevered fourth rotation axis is connected above the second rotation axis (4). (8) A pair of left and right fourth wheels (9) are disposed through them. A pair of left and right fifth wheels (6
) is arranged, and a common drive shaft (2) is provided at the upper rear end.
A pair of left and right drive wheel bodies (to) are disposed via. An endless chain α4, which is an example of an endless rotating body, is stretched over the right wheel group and the left wheel group. The drive shaft a2 is a 0 drive device as appropriate! (not shown). A plurality of trays 4 are swingably attached at predetermined pitches between a pair of left and right endless chains α◆. That is, the connecting bin OB at the appropriate position in the endless chain α4 is made to protrude inwardly, and both sides of the front portion of the tray (2) are swingably attached between the opposing connections 6266. Rollers, which are examples of guided objects, are attached to the outer ends of the connecting bins αG. Bins are connected to both rear sides of each tray, and retaining lobes (6) are attached to the outer ends of these bins. As a result, the four groups of trays move due to the movement of the endless chain Q4, and at this time, a lower horizontal path gJ, which is a lateral path, is formed between the first sleeve body (3) and the third wheel body (7). A vertical path W & (C), which is a vertical path, is formed between the third wheel body (7) and the fourth wheel body (9), and the fourth wheel body (9) and the driving wheel body (towards ) forms an upper horizontal path 4, which is a lateral path, and the bush becomes a return path. Between the rear sides of each tray (to) and both endless chains a4, the tray CL is stretched to the maximum in the vertical path (c).
A telescoping hanger is provided to hold S in a horizontal position. As shown in FIGS. 1 and 4, this telescopic hanger opening is connected to the first link (c) swingably attached to the connecting bin σG, and the connecting pin αQ located one pitch lower than the connecting bin α6. The second link (to) is swingably attached to the bin 4 of the tray 4 corresponding to A center-fold link type consisting of a binding bottle attached to the free end, and a cable type using a chain 4 as shown in Fig. 5 are adopted. Guide rails ga, which are guide bodies for guiding the lobes (b), are provided on both sides of the vertical path (c). The lower horizontal path is provided with a lower supporting and guiding device (1) in the form of an idling roller conveyor that supports and guides the tray (2) facing the bottom surface, and the upper horizontal path is also provided with a similar upper supporting and guiding device (1). A support guide device 3B is provided. A lower lifting device (support) in the form of a belt conveyor is installed between the end of the lower horizontal path (1) and the starting end of the vertical path (C), and this lower lifting device is equipped with a retaining loaf (support). Also, between the end of the vertical path Φ and the beginning of the upper horizontal path Φ, an upper lifting device field having a dog figure is disposed as well.

A guide plate shaft is attached along the above-mentioned return path to guide the opening side of the tray □□□. Further, a discharge conveyor 1:17) is provided below the terminal end of the upper horizontal path @.

In the lower horizontal path 4, the tray (to) moves in a horizontal position because its bottom surface is supported and guided by the lower support and guide device (to), and the sound of the conveyed object is input to this tray (a). At this time, the telescopic hanger opening is in a contracted state. At the end of the lower horizontal path (e), the tray (g) containing the objects to be transported (to) is lifted by the dog in the lower lifting device diagram being held by the retaining rope (6). Therefore, even though the telescopic hanger Q is contracted, it is moved downward along the vertical path (goods) while maintaining its horizontal position. During this movement, the extendable hanger opening is gradually extended. Then the nine trays (to) reach the end of the vertical path (c), and the loaf α
η fits into the guide rail fence to prevent runout, and furthermore (
The telescopic sling opening will be extended to its maximum. With this, the seat tray (G) is supported by the endless chain α4 on the III end side, and the rear end side is supported by the endless chain α4 through the telescopic hanging tool CR3.
It will be supported by K, and will move upward in the horizontal position O. Then, at the end of the vertical path, the dog □□□ of the upper support guide device at> engages with the engaging loaf 4 of the tray 4, and the rear part of this tray (a) is lifted up. Even though the utensil 4 gradually shrinks, the horizontal posture of the tray (a) is maintained.

Before the lifting by the dog (support) comes off, the bottom of the tray (A) is supported by the upper support and guide device c111, and thereafter the tray is supported and guided by the upper support and guide device Gll and moves along the upper horizontal path @ in a horizontal posture. I will do it. At the end of the upper horizontal path 4, the tray (2) is reversed along the drive wheel body 03, and at this time, the objects to be conveyed (to) in the tray (to) automatically fall and are received by the unloading conveyor. This means that the patient will be carried away. Thereafter, the tray is guided between the guide plates and moves along the return path.

Note that the guide rail 4 is constructed as a structure because a horizontal force that supports the tray α9 due to the load of the tray a9 acts on the guide rail 4.

As shown in the above-mentioned examples, stable continuous conveyance with no noise from the conveyed object can be made possible. At this time, the drive devices of both lifting devices shown in FIG. μs are made to be approximately synchronized with the endless chain α, so that the tray αS does not tilt steeply (so that the conveyed objects are not spilled).

In the embodiment, the vertical path (2) is shown as the vertical path, but it is also possible to use a substantially vertical path or an inclined path. Makoto, in the Masahi example, it is transported from the bottom to the top 4! ! ! Although we have described the state in which water is transported, by reverse operation, it is possible to transport water from the upper part to the lower part.

Addition and removal of the trays are performed depending on the conveyance height.

In addition to the rope conveyor type shown in the example, the wet+ support and guide device also has a type in which a guide similar to the guide rail 4 is arranged along the horizontal path ■4 to support and guide the holding loaf 4. It may be. Further, a similar guide may be provided on the return path to guide the rope α force and the retaining loaf.

Effects of the InventionAccording to the present invention having a narrow configuration, a moving force can be applied to each tray by a pair (two threads) of endless rotating bodies on the left and right sides, and in the vertical path, the tray is moved so that the guided body is guided by the guide body. As a result, swinging can be prevented, and the horizontal posture can be maintained with the telescopic hanging tool extended to the maximum. Further, even in the horizontal path, the tray that has swung relative to the endless rotating body is received by the support and guide device even though the telescoping hanger is contracted, so that the horizontal posture can be maintained.

This allows for stable continuous conveyance even though it uses the minimum number of endless rotating bodies, simplifies replenishment and makes the equipment more compact, and also allows for timing adjustment to move the tray in the correct position. You can easily adjust the extension of the ceno and control the drive.
