Description

  The present invention is a metal chip breakage for breaking and transporting metal chips generated in metal processing such as cutting and grinding of metal products such as aluminum, zinc, copper and iron and alloys such as brass and stainless steel. The present invention relates to a transport device.

Conventionally, most of the metal chips generated in metal processing are collected by a specialist, melted and regenerated in a melting furnace, and reused as metal resources such as ingot materials according to materials.
However, these metal chips are generally elongated and curled in a ribbon shape or spiral shape (spiral shape), which is bulky and difficult to handle when transporting or recycling, and lacks work efficiency. As a pretreatment, breaking into short dimensions is performed.
For example, (Patent Document 1) discloses a crushing apparatus in which a rotatable screw having a spiral blade is accommodated in a trough having an opening at the top of one end, and a crushing head is provided at the tip of the screw. It is disclosed.
Further, in (Patent Document 2), metal chips generated in an arbitrary length are finely crushed by supplying from above between a crushing cutter and a crushing roller that are rotatably arranged opposite to each other. A chip crushing method in cutting that discharges downward is disclosed.

JP 2010-234352 A JP 2012-50957 A

However, the above conventional technique has the following problems.
(1) The crushing apparatus of (Patent Document 1) transfers charged metal chips and the like to a crushing head with a screw, and a part of the screw for transferring the chips is a cylindrical trough. Therefore, the metal chips that are elongated and curled in a ribbon shape or a spiral shape (spiral shape) are easily caught in the gap between the trough and the screw, and the transfer efficiency is lacking.
(2) In addition, a spiral ridge opposite to the spiral direction of the screw spiral blade is formed on the inner peripheral surface of the trough, and the screw is driven to rotate in the direction opposite to the spiral direction of the spiral blade. Although it also describes increasing the propulsive force of the object, the structure is complicated and lacks mass productivity, and part of the screw and the spiral ridge are covered with troughs, so it is possible to replace and clean the spiral ridge. It is difficult and lacks maintainability.
(3) The crushing head has a head main body fixed coaxially with the screw and a detachable crushing blade protruding from the outer periphery of the head main body, and is accommodated in a crushing drum connected to the tip of the trough. For this reason, it is difficult to confirm the wear and tear of the crushing blade, and it takes time and labor for replacement work, resulting in poor maintenance and handling.
(4) The bottom of the crushing drum has a discharge port for discharging the processed material to the outside, and the peripheral portion of the discharge port is a fixed blade portion that shears the processed material in cooperation with the crushing blade. It is easy to bite chips between the blade and the fixed blade, lacking in crushing efficiency, and the gap between the crushing blade and fixed blade needs to be adjusted and maintained appropriately, resulting in poor usability and maintainability. .
(5) In (Patent Document 2), the crushing cutter and the crushing roller are mounted alternately in the axial direction of the two rotating shafts, and the tip (cutting edge) of the crushing cutter is connected to the outer peripheral surface of the crushing roller. Since the chips are cut by alternately repeating forward and reverse rotation while being pressed against each other, the crushing cutter is likely to be worn out and lacks long life, and the crushing cutter adjacent in the axial direction is crushed. If it is easy to bite chips into the gap with the cutter, and the side surface of the crushing cutter wears out, the gap may widen and the crushed chips may be discharged. Lack of certainty and usability.
(6) The crushing cutter and crushing roller must repeat the normal rotation that sandwiches the chips from the top to the bottom and the reverse rotation that rewinds from the bottom to the top. Takes too much time and lacks crushing efficiency.
(7) (Patent Document 1) and (Patent Document 2) both have the function of transporting the crushed chips just by dropping them down as they are. A transport device for transporting the crushed swarf is required, the system is likely to be large in size, and installation flexibility, functionality, and efficiency of use of the smashed swarf are lacking.

  The present invention solves the above-described problems, and can efficiently break and transport metal chips with a simple configuration, is excellent in compactness and installation flexibility, and protrudes from the outer periphery of the rotating shaft at the breaking portion. Since the rupture is performed with the plate-shaped or bar-shaped protrusions, the rupture capability is high, and it is difficult for metal chips to bite at the rupture portions, and the occurrence of breakage, wear, etc. can be reduced. The purpose is to provide a metal chip breaking and conveying device that is excellent in durability and long life, and can be easily replaced in the event of breakage or wear, and has excellent maintainability and usability. .

Means for solving the problems, and actions and effects obtained thereby

In order to solve the above problems, the metal chip breaking conveyance device of the present invention has the following configuration.
The metal chip breaking and conveying apparatus according to claim 1 of the present invention is a metal chip breaking and conveying apparatus that breaks and conveys metal chips generated by metal processing, and the metal chips are introduced into the upper part. A housing having an insertion opening, a first rotating shaft horizontally installed in the housing, a second rotating shaft horizontally and parallelly spaced apart from the first rotating shaft in the housing, and the A rupture region in which protrusions protrude from the outer periphery of the first rotation shaft and the second rotation shaft, and spiral blades are formed on the outer periphery of the first rotation shaft and the second rotation shaft other than the rupture region, and the insertion port A breaking portion having a transfer region for moving the metal chips thrown into the breaking region, and the breaking portion disposed below the breaking portion between the first rotating shaft and the second rotating shaft. A transport unit that receives and transports the ruptured chips that are broken and dropped, and discharges them outside the housing; and A cover portion covering the feeding portion; and an opening portion that is formed on the upper surface side of the cover portion so as to face the rupture region of the rupture portion and allows the rupture chips falling from the rupture portion to pass therethrough. It has a configuration.
This configuration has the following operations and effects.
(1) A casing having an inlet into which metal chips are placed at the top, a first rotating shaft horizontally installed in the casing, and a first rotating shaft horizontally spaced in parallel with the first rotating shaft in the casing. Spiral blades are formed on the outer periphery of the second rotating shaft, the first rotating shaft, and the outer periphery of the first rotating shaft and the second rotating shaft. Since it has a rupture part having a transfer area for moving metal chips introduced from the inlet to the fracture area, the metal chips introduced from the inlet are reliably moved to the fracture area by the spiral blade of the transfer area The protrusions and spiral blades provided on the outer circumferences of the first rotating shaft and the second rotating shaft can be efficiently broken, and the reliability and efficiency of the metal chip breaking work are excellent.
(2) Since the first rotating shaft and the second rotating shaft of the fractured portion are horizontally mounted in a housing having an inlet into which metal chips are introduced at the top, the fracture status at the fractured portion is visually confirmed from the outside. It can be easily detected when the protrusion is deformed or damaged, and can be easily replaced when the protrusion is fixed by bolting. Excellent.
(3) By providing a transport unit that is disposed between the first rotating shaft and the second rotating shaft of the breakage portion, receives the breakage chips that are broken and dropped at the breakage portion, and transports and discharges out of the housing. The broken chips that are broken and dropped at the broken portion can be reliably conveyed to perform subsequent processes, and the use efficiency of the broken chips is excellent.
(4) Since the cover portion is provided so as to cover the conveying portion, foreign matter is not mixed during the conveyance and the broken chips are not scattered around, so that the reliability of conveying the broken chips is excellent.
(5) Since it has an opening portion that is formed on the upper surface side of the cover portion so as to face the rupture region of the rupture portion and allows rupture chips falling from the rupture portion to pass therethrough, the conveying portion conveys the rupture chips that are broken and dropped at the rupture portion. It can be received and transported reliably and has excellent transport reliability.
(6) The breaking part and the conveying part are integrated, and it is compact and excellent in installation flexibility and functionality.

Here, as the case, a metal case such as steel or stainless steel is preferably used. The inlet may be any one that allows metal chips to be dropped from above the breakage part, and the shape, size, arrangement, etc. can be selected as appropriate, but the entire upper surface of the housing is open. It is preferable because it has excellent workability for feeding metal chips. In addition, an opening / closing lid may be provided at the charging port, or a supply pipe for supplying metal chips may be connected.
The first rotating shaft and the second rotating shaft of the breaking portion are horizontally mounted in the housing, but both end portions are protruded to the outside of the housing, and are rotatably held by bearing portions arranged outside the housing. It is preferable. By disposing the bearing portion outside the housing, the inside of the housing can be used effectively, and metal chips are not caught in the bearing portion, and broken chips and the like are not attached. Excellent stability of operation and maintainability of fractured part.
The first rotating shaft and the second rotating shaft can be rotated by inputting the power of the drive motor from one end side of the first rotating shaft and the second rotating shaft. At this time, the first rotating shaft and the second rotating shaft may be rotated by separate drive motors, or a pulley, a sprocket, etc., and a power transmission member such as a belt, a chain, etc. are combined and rotated by a single common drive motor. May be. In addition, the rotation direction of a 1st rotating shaft and a 2nd rotating shaft can be selected suitably.
Although the rotation speed of a 1st rotating shaft and a 2nd rotating shaft changes with materials etc. of a metal chip, in the case of aluminum, 5-20 rpm, Preferably 8-12 rpm is desirable. As the rotational speed becomes slower than 8 rpm, the breaking ability tends to decrease. As the rotational speed becomes faster than 20 rpm, the breaking ability tends to decrease and the load on the machine such as biting tends to increase. In particular, if it is slower than 5 rpm or faster than 20 rpm, the breaking ability is remarkably lowered, and sufficient breaking is difficult, which is not preferable.

The number of protrusions in the rupture region, the arrangement interval, and the like can be appropriately selected. However, when the positions are shifted in the axial direction of the first rotation shaft and the second rotation shaft, the protrusions do not interfere with each other. It is preferable that wear and biting of metal chips hardly occur and the metal chips can be efficiently broken. In particular, by arranging a plurality of protrusions radially on the outer periphery of each of the first rotating shaft and the second rotating shaft, the efficiency of fracture is excellent. At this time, by shifting the phases of the protrusions of the first rotating shaft and the second rotating shaft, the metal chips are not broken in a state compressed by the protrusions, and wear and biting of the metal chips are prevented. It does not easily occur, and it has excellent durability and long life of the protrusions, as well as excellent equipment operability and breaking efficiency. In addition, you may arrange | position a some protrusion part at random.
The shape of the protrusion can be selected as appropriate, and may be formed in a rod shape such as a columnar shape or a prismatic shape, or may be formed in a flat plate shape, an angle shape, or the like. In particular, the protrusions formed in a flat plate shape, an angle shape, and the like are not easily deformed, have excellent durability, and can efficiently break the metal chips using the end face.
The transfer region is formed in at least a part of the first rotating shaft and the second rotating shaft other than the broken region, and the transfer region is formed over the entire range of the first rotating shaft and the second rotating shaft other than the broken region. By forming, the metal chips to be charged can be efficiently collected in the rupture region and ruptured reliably in a short time, and the rupture reliability and efficiency are excellent.
The arrangement of the breaking area and the transfer area can be selected as appropriate, but it is preferable to arrange the breaking area at the center in the longitudinal direction of the first rotating shaft and the second rotating shaft and to arrange the transferring areas on both sides thereof. By placing the rupture area in the center, the metal chips can be ruptured quickly after being charged, and the metal swarf in the housing is efficiently gathered from the transfer areas on both sides to the rupture area in the center. Can break. Each spiral blade selects the direction of twisting according to the rotation direction of the first rotation shaft and the second rotation shaft so that the metal chips move toward the fracture region.
Although the conveyance part should just be what can convey the fracture | ruptured chip | tip broken by the fracture | rupture part, a screw conveyor, a screw feeder, etc. are used suitably.
