Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device for intensively conveying chips and other conveyed materials such as granular materials and solid materials for metal processing machines.

2. Description of the Related Art As a chip conveyor device for conveying chips of a metal processing machine, for example, a scraper type or a hinge plate type is generally known.

The former scraper type uses steel plate scrapers placed at appropriate intervals between two endless bear chains placed on both sides to remove chips that have fallen into the trough along the bottom surface of the trough. In the latter hinge plate type, the chips that have fallen into the trough are directly received by a conveyor plate and conveyed as they are as the conveyor rotates. Since these conveyor devices are designed and manufactured for the purpose of conveying a large amount of chips, each trough is a box with a rectangular cross-sectional shape and has a large area for accommodating the falling chips. However, on the other hand, for processing machines that generate relatively few chips, attempts have been made to use a trough with a smaller overall size in order to eliminate waste of storage area, but this method is expensive in terms of manufacturing costs. At present, large-volume conveyor devices are often used as they are because they cannot be expected to be very effective. In this sense, conventional chip conveyor devices have a lot of wasted chip accommodating area, and are not very desirable from an economic standpoint. In addition, to make this trough, thin steel plates are bent and joined by welding, etc. If the trough is made to be long, angle iron is used as a reinforcing framework, or the shape of the bend is devised. This gave it rigidity.

For this reason, the production costs for these series are quite high, and there has been a strong desire for ways to improve this. In the present invention, the conveyed object is particularly limited to chips. However, the purpose is to provide an extremely innovative conveyor device that fundamentally eliminates the storage area for chips and other conveyed objects and the waste of manufacturing costs found in conventional chip conveyor devices. shall be.

Another object of the present invention is to use an existing conveying trough. By using a cylindrical tube body and using an existing link chain for conveyance, it is possible to provide a durable and extremely economical conveyance device.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 indicates a conventional scraper type chip conveyor device. Chips, that is, chips generated by cutting by a metal processing machine (not shown) pass through the hopper 3 and fall onto the bottom surface of the conveyance trough 2. This chip is attached to a blade 4A attached to an endless link chain 4 which is rotated clockwise via a belt 6 by a drive motor 5.
is scraped out along the bottom of the trough and conveyed to the discharge port 7.
More is discharged to the outside. The conveying device 10 of the invention, shown in detail in FIGS. 2 to 10, includes a conveying trough 13 supported by a pedestal 11. As shown in FIGS.

The trough 13 is a long vibrator made of a cylindrical tube with a circular cross-sectional shape, and is preferably made of a member such as a generally commercially available carbon steel pipe for piping (commonly called a gas pipe), and the pipe diameter is Select as appropriate depending on the amount of objects to be transported. A plurality of openings 14 are provided on the upper surface of the transport trough 13 at appropriate positions between the starting end and the terminal end, and a hopper 15 for receiving the transported object is fixed to each opening.

The trough 13 is equipped with a driven device 40 (described later) at its starting end and a drive device 20 (described later) at its terminal end, and inside there are a plurality of endless link chains 17 driven by the driving device 20 and the driven device 40. They are inserted in parallel.

As shown in FIG. 9, this chain 17 is made up of oval-shaped links connected alternately and orthogonally, and conveys the articles put into the hopper 15 to the discharge port 27, which is the terminal end of the trough 13, and discharges them. After that, it returns to the starting end of the trough through the outer lower part of the trough 13, passes through the driven device 40 at the starting end, enters the trough again, and circulates. The dimensions of the links of the chain 17 may be set arbitrarily depending on the diameter of the trough 13 and the amount of material to be conveyed, but the short axis is 15 to 25 hours, and the long axis is 20 to 4 hours.
degree is preferred. 57 is a flange for connecting the transport trough 13.

The plurality of frames 11 for supporting the conveyance trough 13 are made lower one after another from the terminal end toward the starting end in order to make the trough 13 slope downward from the terminal end toward the starting end.

As will be described later, the slope of the trough 13 is for collecting moisture attached to or contained in the transported objects. Next, a drive device 2 provided at the end of the trough 13
0 is composed of a drive motor 19, a reducer 23 for adjusting the rotational speed of the drive motor 19, and a drive roller 29 for circulating the link chain 17 by receiving the rotational force of the reducer. The rotational force is belt 21
and 25 to the reduction gear 23 and the drive roller 29. As shown in FIG. 4, this drive roller 29 is
It has a roller body 29B that is rotatably supported by a bearing 29A fixed to the housing 26 with a bolt or the like and housed in the housing 26, and a link chain 17 is attached to the outer periphery of the roller body 29B.
In order to reliably drive the chain, a K-shaped groove 29C is provided that strongly engages with the chain link. In addition, 29D is reducer 2
This is a drive gear that transmits the rotation of No. 3 to the drive roller main body 29B. The housing 26 has a flange 53 and a trough 13.
(Fig. 3), and a chip carrier 9 (Fig. 1) is placed under the downwardly facing open end 28 of the housing 26. Install conveyors, etc. 40 is a driven device, which is composed of a first tension roller 43 and a plurality of idlers 49;
It is accommodated in a box-shaped housing 51 attached to the starting end of the trough 13 via a flange 55.

A first tension roller 43 supported by the housing 51 via a bearing is used to adjust the tension of the endless link chain 17, and this adjustment is performed using attached bolts 45 and nuts 47. Further, the lower bottom of the housing serves as a container for temporarily storing fluids, such as water and oil, and is provided with a discharge pipe 59 through which the fluid is stored in a drain tank 60. As shown in FIG. 5, the idler 49 includes a roller body 49B supported by a bearing 49A fixed to the housing 51.

A plurality of grooves 49C are provided on the outer periphery of the roller main body 49B to ensure smooth rotation of the link chain 17.
Further, a lower outer peripheral housing 31 of the trough 13 is attached near the drive device 20 at the end of the conveying trough 13, and an eccentric piece means 35 is provided inside the housing 31.

This eccentric piece means 35 is connected to the belt 3 from the drive motor 19.
The configuration is shown in Figures 7 and 8.
The details are shown in the figure. As is clear from both figures, the eccentric bridge means 35 is mounted in the same way as the drive roller 29 and idler 49, and the bridge body 35B is rotatably supported by a bearing 35A fixed to the housing 31. Piece body 35
B consists of a piece having arcuate surface parts 35B'' and 35B'''' on the upper and lower surfaces, and a shaft 35E that passes through the top of the piece near the arcuate surface part 35B'', and the piece is eccentrically fixed to the shaft 35E with a set screw 35C. and is supported by a bearing 35A through a shaft 35E.
Therefore, when rotated via the drive gear 35D attached to the shaft 35E, eccentric rotation is performed. In addition to the eccentric piece means 35, the housing 31 accommodates a pair of second tension rollers 33, and as shown in FIG. 10, this roller 33 carries a roller body 33B which is pivotally supported by a bearing 33A.

This roller main body 33B has a plurality of rolling surfaces that support the chain 1.
Since it is merely for tensioning the roller 7 outward, there is no need to form something like the groove 49C (FIG. 5) formed in the roller body 49B of the idler 49. Note that guide rollers 39 and 41 assist in driving and guiding the link chain 17, and are provided at appropriate locations depending on the length of the trough to catch slack in the chain.

This roller 41 is provided with a second roller to prevent the chain 17 from becoming entangled.
It is preferable to have a structure similar to that of the tension roller 33 (FIG. 10). Next, to describe the operation of the present invention, conveyed objects such as chips generated by cutting by a large number of metal processing machine lines (not shown) are thrown into the hopper 15 into the conveying trough 13 using a conveying device (not shown) or manually. It is dropped and loaded onto the endless chain 17.

Since this endless chain 17 is circularly driven in a counterclockwise direction by a driving device 20 and a driven device 40, the conveyed objects loaded on the chain 17 are transported through the conveying trough 13.
It moves to the left in FIG. 3, reaches the position of the drive roller 29 of the drive device 20 provided at the end of the trough, falls downward from the discharge port 27, and is stored in a storage box or transport vehicle. be done. The link chain 17, which has come out of the conveyance trough 13 after discharging the material, moves to the right under the trough and reaches the position of the eccentric piece means 35.

This piece means is rotationally driven by the drive motor 19, and is a device for shaking off the remaining conveyed material that cannot be completely discharged from the discharge port 27 and still adheres to the link chain 17. A piece body 35B of this piece means 35 is housed in the same housing 31 and eccentrically rotates in contact with the chain between a pair of second tension rollers 33, 33 that tension the chain 17 downward. Farthest arc surface part 3
Since the 5B'' chain is struck, the chain is vibrated. This vibration and the rotating force of the sliding contact of the arc surface portion 35'' make it possible to completely shake off the firmly adhered conveyed object. Note that a storage box is provided below the housing 31 to receive the transported objects that have been thrown away. The link chain 17, which has completely brushed off the adhered conveyed material, further moves to the right below the conveyance trough 13, returns to the driven device 40 provided at the starting end of the trough via guide rollers 39 and 41, and Reenter the trough and repeat the circulation process.

The idler 49 of the driven device 40 is for smoothly turning the link chain 17, and the first tension roller 43 serves both to adjust the tension of the link chain 17 and, in this embodiment, to turn the chain.

To tension the chain, loosen nut 45 and bolt 47.
To move the chain upward and conversely loosen the chain, loosen the nut 45 and move the bolt 47 downward.
If the conveying trough 13 is inclined downward from the terminal end to the starting end as in this embodiment, the link chain 17
Moisture adhering to or contained in the conveyed articles flows down the inside of the trough toward the starting end, and can be collected into the drain tank 60 from the piping 59 provided in the housing 51 at the starting end.

This piping can be provided at several locations depending on the length of the trough to achieve concentrated collection of fluids. In this way, the conveying device 10 of the present invention repeats the above-mentioned cycle, and can convey a large amount of objects of various shapes inputted from each hopper, and discharge them in a concentrated manner.

The transport trough through which the link chain is inserted is the pipe body of an existing gas pipe, etc.! quantity and shape and properties of substances;
Since the diameter can be selected and used depending on the size, there is no wastage in storage area compared to conventional box-shaped ones, and considerable cost savings can be expected in terms of manufacturing costs. Furthermore, since a commercially available link chain may be used, it is highly durable and can be manufactured economically. Furthermore, in addition to being able to centrally collect fluids that are attached to or contained in conveyed objects, it is also possible to convey them to relatively high places by combining them with conventional conveying equipment as shown in Figure 1. In addition to being able to concentrate on the transport vehicle 9 provided below the discharge port 7 of the device 1, it can also be combined with conventional devices in various ways.
You can create a layout according to your purpose.
