Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a chip conveying cart for conveying chips generated by a machine tool.

[Prior art] Generally, chips generated in a factory with machine tools are collected in a chip carrier, and transported by the chip carrier to a location near the hopper, and the chips in the chip carrier are transferred to the hopper. Can be collected. A conventional chip transport vehicle used for transporting chips has a structure that consists of a container with an open top, wheels for running, and a handle for pushing.

[Problem that the invention aims to solve] Chips generated by machine tools are transported in a container on a chip carrier, but the chips generated by machine tools contain a large amount of cutting oil. It is
When chips are transported in a container on a chip transport vehicle, they are transported to the hopper while containing a large amount of cutting oil.
When transferring chips to the hopper, there is a problem in that the cutting oil scatters and is scattered around or on the worker.Also, a large amount of cutting oil is put into the hopper and removed from the hopper. There is also the problem that there are disadvantages when transporting the products by transferring them to a truck.

[Means for solving the problem] In order to solve the above-mentioned problem that cutting oil is conveyed to the hopper in a state containing cutting oil, an oil storage space is provided between the bottom of the container and the bottom plate of the container. A bottom plate was stretched over the entire surface, a perforated plate such as a net plate was provided on the inner bottom plate, and a discharge means was provided in the container to discharge the oil accumulated in the oil reservoir. As a result, even if chips containing cutting oil are put into the container, the cutting oil drips from the perforated plate of the inner bottom plate into the oil pool space and accumulates.
The cutting oil accumulated in the oil collecting space can be discharged by the discharge means, and the oil-drained chips can now be conveyed to the hopper. In addition, if the entire inner bottom plate is made of a perforated plate such as a mesh plate, the chips tend to get caught on the entire surface of the inner bottom plate, making it impossible to completely discharge the chips, and when the container is overturned to discharge the chips, the cutting oil leaks. In order to solve the problem of spillage (in order to eliminate this problem, cutting oil must be drained every time it is transported), the rear part of the inner bottom plate on the handle side is made of a perforated plate like a net plate, and the inner bottom plate is The remaining part other than the rear part was made of a non-perforated flat plate. By doing this, even though the cutting oil is drained, there are fewer parts where the chips get caught, and the chips can be completely discharged.Also, even if the container is tipped over to drain the chips, the cutting oil can be easily removed. This eliminates the hassle of draining cutting oil every time it is transported.

[Embodiment] As shown in FIGS. 1a, b, c, d, and e, the chip conveying cart A is mainly composed of a container 1, wheels 2, and a handle 3.

The nut 38 is inserted into the hole 40 of the connecting pin 37, and the nut 38 is screwed onto the threaded portion 41 at the tip of the connecting pin 37. Cart holder 1
9 has an upper support member 20a and a lower support member 20b on the inner surface.
The insertion groove 20 is inclined by attaching the two upper and lower parts. Although the upper support member 20a is horizontal,
The lower support member 20b is inclined so as to descend downward toward the front. The locking body 17 of the chip conveying cart A described above can be locked in this insertion groove 20. A hopper 22 is provided below the discharge port 25 of the conveyance path 23.

Next, the operation of conveying chips generated by the machine tool to the hopper 22 using the chip conveying cart A will be explained.
Chips generated by the machine tool are collected in a container 1 of a chip carrier A. At this time, since the porous plate 9a on the inner bottom plate 9 where chips tend to get caught is only in a part of the rear portion, the chips are less likely to get caught on the inner bottom plate 9. Moreover, since there is a rising edge 10 around the non-perforated flat plate 9b, chips are less likely to get caught in this point as well. When the container 1 of the chip carrier A is full of chips, the chips are transported by the chip carrier A to the transport path 2 of the vertical transport device B.
It is carried to the entrance 24 of 3. By the way, the chips placed in the container 1 of the chip conveyor A contain cutting oil, and the cutting oil drips from the perforated plate 9a of the inner bottom plate 9 and accumulates in the oil reservoir space 8, which prevents cutting of the chips. Oil is removed. When the chip carrier A reaches the vertical transport device B, the carrier holder 19 has been lowered to the lowest position, and when the chip carrier A enters from the entrance 24, the chip carrier A enters the carrier holder 19. . At this time, the locking body 17 of the chip carrier A is inserted into the insertion groove 20 of the carrier holder 19, and the chip carrier A is held by the carrier holder 19. The locking body 17 is inserted into the insertion groove 20
When inserted into the lower support member 2, the stopper plate 21 prevents the lower support member 2
0b is inclined and the lower edge 28 of the locking body 17
Since a is inclined, it is held so that it does not move backward. When the chip conveying cart A is held by the cart holder 19, the cables 27 are attached to the cart holder 1.
The cable 27 is driven to pull up the cable 27.
The carriage holder 19 rises upward. At this time, the guide rollers 30 roll along the roller guide rails 29, and the truck holder 19 is raised in a horizontal state. When the carriage holder 19 rises upward, the guide roller 30 hits the stopper 31 and does not move upward any further, but from this state the carriage holder 19 is further pulled up by the cable 27.
Then, the carriage holder 19 moves around the guide roller 30.
gradually rotates as shown by the imaginary line in FIG. 2, the trolley holder 19 falls over, and the lifting of the cable 27 is stopped. When the cart holder 19 falls, the chip conveying cart A
also fell over, and the chips in the chip conveyor A were discharged from the outlet 25.
It is discharged from the hopper 22 and thrown into the hopper 22. At this time, since the front part of the inner bottom plate 9 is a non-perforated flat plate 9b, the cutting oil accumulated in the oil pool space 8 is removed from the hopper 2.
It will not spill over to 2. When the chips in the chip conveying truck A are discharged, the cable 27 is driven in the opposite direction to the above to pull down the truck holder 19, and the truck holder 19 moves in the opposite direction to the above and becomes horizontal. , the trolley holder 19 moves down the conveyance path 23. When the cart holder 19 descends to the lowest position, the chip conveying cart A is extracted from the entrance 24. By repeating such an operation, the chips of the chip transport vehicle A are transported one after another, and the chips are accumulated in the hopper 22. Hopper 22
When a predetermined amount of chips accumulates, they are discharged from the hopper 22 onto a truck and transported by the truck. When a large amount of cutting oil accumulates in the oil reservoir space 8 of the chip conveying truck A, the discharge hose 15 of the discharge means is removed from the locking part 16 and is discharged via the discharge pipe 14 and the discharge hose 15. Also, when cleaning the oil pool space 8, use the screw tool 1.
3 and open the perforated plate 9a upward.

[Effects of the invention] As described above, the present invention has an inner bottom plate stretched over the entire surface of the container for storing chips with an oil pool space between the bottom plate and the bottom plate of the container. The container is equipped with a perforated plate and a discharge means for discharging the oil accumulated in the oil pool, so even if chips containing cutting oil are put into the container, the cutting oil will flow from the perforated plate of the inner bottom plate to the oil pool space. The cutting oil that drips and accumulates in the oil storage space can be discharged by a discharge means, and the oil-drained chips can be conveyed to the hopper, and when the chips are transferred to the hopper, the cutting oil is removed. It is possible to eliminate the possibility of scattering and scattering around the surroundings or attaching to the worker, and in addition, the rear part of the inner bottom plate on the handle side is made of a perforated plate like a net plate, and the part other than the rear part of the inner bottom plate is made of a perforated plate. The remaining part is a non-perforated flat plate, so even if the cutting oil drains, the parts other than the rear of the inner bottom plate are non-perforated flat plates, so there are fewer areas where chips can get caught (chips easily get caught in perforated plates). ), when the container is tipped over so that the rear side on the handle side is facing up, the chips can be discharged smoothly and completely. The flat perforated plate prevents cutting oil from spilling (if the entire surface is a perforated plate, cutting oil will spill when the container is tipped over to discharge chips).
This eliminates the hassle of draining the cutting oil each time it is transported, and since the front side wall of the container is a sloped surface that projects upward, it is easy to remove the cutting oil from the front when tipping the container over and discharging the chips. The side wall of the part is slanted diagonally downward to allow chips to be discharged more smoothly.
