"Problems to be Solved by the Invention" The conventional chip conveyor described above is a small-scale conveyor, and is complex and unsuitable for manufacturing a large one.

"Means for Solving the Problems" The present invention solves the above conventional problems, and the trough is composed of a conveyor head section, a corner section, a plurality of straight sections, and a conveyor end section. A first motor and a second motor are provided which are synchronized with the conveyor end, and a first roller chain sprocket and a second roller chain sprocket are respectively driven by the first motor and the second motor and attached to the inside of the trough outer plate. The first drive shaft and the second drive shaft are pivotally supported on the trough outer plate, and the two drive shafts are connected in an endless manner that can continuously surround the first roller chain sprocket and the second roller chain sprocket.
The roller chains of the strips are connected vertically by sandwiching the chute plate,
Scrapers are attached to the roller chain at desired intervals, and multiple chip scraping rollers are installed on the conveyor head in conjunction with the first drive shaft to scrape the chips to the chip falling port. Since it is a chip conveyor that drops chips, it is easy to manufacture long conveyors, and by installing two motors to reduce the load on the roller chain, it is possible to manufacture chain conveyors over 100 m in one piece, and by installing chip scraping rollers. It is possible to prevent chips from being caught in the trough lower roller chain feeding section.

"Example" An embodiment of the present invention is shown in FIGS. 1 to 23.

The overall shape of the chip conveyor is shown in Fig. 1, and the main parts include a conveyor head section 11 corner section 2, straight section unit 3, conveyor end section 4, first motor 5, second motor 6, and chip scraping roller 7. The desired total length of the chip conveyor can be extremely easily manufactured by determining the number of linear section units 3 to be used.

As shown in FIG. 2, the internal structure of the chip conveyor is such that two roller chains 10 are arranged on the left and right in a trough formed by a trough body 8 and a chute plate 9, scrapers 11 are attached at desired intervals, and a chute plate 9 is attached to the trough. A roller chain 10 is arranged above and below the conveyor head section 1 to the conveyor end section 4 and connected in an endless manner like a vine. It has a structure that prevents it from falling. Also, trough body 8, chute plate 9, cheno guide 1
2 are tightened and connected by bolts 13.

The conveyor head section 1 includes a sprocket 14 connected to a first motor 5 by a chino (not shown), a drive shaft 15,
It has a roller chain sprocket 16 and is coupled to a trough head body 18 via a bearing 17. The sprocket 19 is connected to the sprocket 20 by a chino (not shown), and the sprocket zO is connected to the shaft 21, chino guide roller 22, chip scraping roller 7, and the bearing 2.
3 to the trough body 8.

Therefore, the rotational force of the first motor 5 rotationally drives the roller chain sprocket 16, and also rotationally drives the chip scraping roller 7, which drives the roller chain 10.

As shown in FIG. 5, the roller chain sprocket 16
roller chain 1 by rotating in the direction of the arrow.
0 is driven in the direction of arrow M, and the chip scraping roller 7 rotates in the direction of arrow N.

This allows roller chain IO and scraper 1
The chips conveyed by 1 rotate around the drive shaft 15 and fall in the direction of arrow O. However, in rare cases, chips that are entangled with the scraper 11 do not fall and enter the 10-pass feeding section of the low chain at the bottom of the trough body 8. However, it gets caught by the chip scraping roller 7 and is forcibly scraped off. It is even better to insert a collar 24 between the roller chain sprocket 16 and the trough body 8 to prevent chips from getting wrapped around the drive shaft 15.

Figures 7 and 8 show the roller chain 10 and scraper 1.
1 and the chip scraping roller 7. The chip scraping roller 7 has a shape with several notches '25 on the circumference so that chips can be caught. Several scrapers are attached depending on the length of the scraper 11. Although it is installed close to the orbit of the scraper 11, the roller chain 10 is installed so that it does not collide with the chip scraping roller 7 due to the swinging of the roller chain 10. A chino guide roller 2z is disposed at the orbital position so that the scraper 11 does not come into contact with the chip scraping roller 7 even if the roller chain 10 and the chino guide roller 2z come into contact.

At the end of the conveyor, a sprocket z6 connected to the second motor 6 by a chino (not shown), a drive shaft 27, a roller chain sprocket 28, and a slide plate z9 are arranged as shown in Fig. 4, and bearings are installed. The slide plate 29 is attached to the trough end body 31 through the roller chain sprocket z8 of the drive shaft z7, and the chute plate 9
Since the drive shaft 27 and the chute plate 9 are mounted on top of each other, there is no gap between the drive shaft 27 and the chute plate 9 even when the bearing 30 is moved back and forth to adjust the tension of the roller chain 10.

The slide plate z9 is made in the shape shown in FIG. 9, and the pipe 32
and plate 33. The vibrator 32 is selected to have a size that allows the drive shaft z7 to pass through it.

As shown in FIGS. 4 and 6, the trough end main body 31 has a shape in which the central part of the rear end is bulged, and the chips that have fallen into the trough feeding section are collected and scraped back onto the upper side of the chute plate 9 by the scraper 11. It has a scooping structure.

The straight section unit 3 is assembled with a trough body name, a chute plate 9, and a cheno guide 12 as shown in FIG. Consisting of a plate positioning plate 35, a roller chain backing plate 36, and a flange 37, the chute plate positioning plate 35 has a required height in order to secure the space necessary for the roller chain 10 and scraper 11 to be conveyed under the trough outer plate 34. It is appropriately attached to the trough outer plate 34 by welding or the like, and is provided in order to extremely facilitate the assembly work of this chip conveyor. The roller chain cover plate 36 is provided at the feeding track position of the roller chain 10, and is attached for the purpose of increasing the durability of the chip conveyor, reducing the thickness of the trough outer plate 34, and reducing manufacturing costs. Flanges 37 are attached to both ends of the trough outer plate 34, and have machine holes 38 as shown in FIG. 1O to facilitate connection of the troughs. In order to assemble the chute plate 9 and the chino guide 12, the trough outer plate 34 has required holes 39 in its both side plate portions.

The chute plate 9 consists of a chute plate 40, a connecting plate 41, and a connecting side plate 42, each having a shape as shown in FIGS. 12 and 13.
Connecting plate 41. The connecting side plate 42 is attached only to one side of the chute plate 40, and as shown in FIG.
When assembling and connecting the chute plate 9, if the one in front of the scraper 11 is lifted up, the scraper 11 will collide, so the chute plate 9 at the rear is sandwiched between the connecting plate 41 and the connecting side plate 42, It has the function of preventing the front chute plate 9 from lifting up and preventing chips from getting caught in the joints of the chute plate 9 and becoming resistance to the scraper 11.

, the chain guide 12 consists of a roller chain guide plate 43 and a reinforcing plate 44 having the shapes shown in FIGS. 15 and 16, and has sufficient strength to withstand the running resistance of the roller chain 10. To guide ~
, has a function of preventing chips from being sprinkled on the roller chain 10.

The corner portion 2 has a structure as shown in FIGS. 17 and 18, and has a trough bent at a desired angle and has a vine shape through which the roller chain 10 and the scraper 11 pass. However, since the roller chain guide plate 43 located above the roller chain 10 is the part on which the most force is applied, a reinforcing plate 44 is attached to ensure sufficient strength.

The difference from the cross-sectional shape of the straight section unit 3 is that there is a roller chain guide plate 43 also on the roller chain feeding section under the trough.
In addition, a reinforcing plate 44 is provided to prevent the roller chain 10 from shifting laterally.

The scraper 11 has a shape as shown in Fig. 19, and is attached to the roller chain I as shown in Fig. 20.
It is tightened to the L-shaped attachment 45 of O with a bolt.

Next, the direction of movement of the scraper 11 on the chute plate 9 is as follows:
As shown in FIG. 21, the chip scraping plate section 46 is attached to the rear of the roller chain attachment section 47. This is because if there is strong resistance due to foreign matter on the chute plate 9, the scraper 11 will lift up and release the resistance, which will cause the scraper 11 to fall off from the roller chain IO.

In this case, the gap between the scraper 11 and the chute plate 40 can be 21101 mm or less.

As a modification, a chip conveyor with a length of 50 m or less may have one conveyor head.

If you want to further reduce production costs for a chip conveyor that is installed in a location where daily inspection by workers is easy, install a second conveyor.
The scraper 11' is made as shown in FIG. 2, and the scraper 11' is installed in the direction of movement so that the chip scraping part 46' is located ahead of the roller chain attachment part 47' as shown in FIG.

In this case, it is necessary to widen the gap with the chute plate 9' to about 5rIrM to prevent the scraper 11' from falling off from the roller chain 10 due to being caught.

This scraper 11' has improved chip discharge performance at the chip discharge section, and can eliminate the chip scraping roller.

"Effects of the Invention" The present invention has the above-mentioned configuration. (1) By connecting the troughs with bolts at the flange portions, a long conveyor can be easily manufactured by unit assembly.

(2) Installing a chip scraping roller prevents chips from being drawn into the roller chain feeding section on the lower side of the trough.

(3) By providing the chute plate positioning plate on the trough body, assembly of the conveyor has become extremely easy.

By attaching a connecting plate and a connecting side plate to the chute plate, the connecting position of the chute plate is made easy.

(5) By inflating the central part of the rear end of the trough end, chips are removed from the sprocket rotating part and easily splashed onto the chute plate by the scraper.

(6) We decided on a shape for the scraper that has a simple structure and ensures sufficient strength.

(7) Determine the relationship between the direction of movement and the shape of the scraper.

This prevents the scraper from hitting foreign matter on the chute plate and falling off the roller chain.

(8) Conventionally, there was no multiple drive system for chip conveyors, but one drive system each for the conveyor head and conveyor end.
A total of two motors are installed to reduce the load on the roller chain, making it possible to manufacture chip conveyors over 100 meters in length.

(9) By making the chute plate, which requires the most durability, a separate part from the trough body, a highly durable trough can be made by increasing the thickness of only the chute plate.

In other words, since the plate thickness of the trough body may be between 2.3 and 3.2, it is possible to manufacture the conveyor at low manufacturing cost. Similarly, the roller chain backing plate is installed in a highly durable trough.

It has extremely excellent effects such as.
