Abstract

PURPOSE:To surely convey out chips having resulted from cutting, by providing triangular top and side push members on a reciprocating bar at equal intervals in the longitudinal direction thereof, and supporting the reciprocating bar movably back and forth on the inside bottom surface of a gutter-like conveyance passage so that the bar cooperates with holding members on the inside surface of the conveyance passage. CONSTITUTION:When a reciprocating bar 9 is moved forth by a power cylinder as chips C having resulted from cutting are supplied from the surface of the bed of a machine tool into a conveyance passage 1, the chips are pushed forth by the engaging portions 15, 18 of slightly-long triangular side push members 17 on both the sides of the reciprocating bar and triangular push members provided on the top of the bar at equal intervals in the longitudinal direction thereof. At that time, the chips C are led in guide paths 25 defined by triangular holding members 2 provided on the internal surfaces of the sides of the conveyance passage 1. When the reciprocating bar 9 is then moved back, the chips C are engaged by holding portions 24 so that the chips are kept from moving back. When the reciprocating bar 9 is thereafter moved forth again, the chips C are pushed forth further. The chips C are thus conveyed.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a chip transport conveyor that forcibly transports particularly thick and large cutting chips discharged from various machine tools within a transport path by reciprocating movement of a reciprocating rod.

PRIOR ART Conventional conveyors of this type have a periphery on the underside of the reciprocating rod that slides on the bottom surface of the conveying path so that not only linear cutting chips but also granular or powder cutting chips can be transported. A box-shaped extrusion member is provided which is welded to the front surface of the extrusion member, and a chip extrusion surface having a relatively wide area is formed on the front surface of the extrusion member. However, according to these conventional competitions 77, when transporting thick and large cutting chips discharged from large machine tools,
There is a disadvantage that the extrusion member is damaged in a short period of time because the extrusion surface receives strong resistance from the cutting chips entangled with each other in the conveyance path. In addition, since the conventional type does not have a means for guiding the movement of the reciprocating rod in the conveyance path, it is difficult to reciprocate the reciprocating rod in a straight line when conveying large cutting chips, and the drive unit and There was also the problem that the connecting parts with the reciprocating rod were damaged early.

Purpose of the Invention This invention was made in view of the above-mentioned conventional disadvantages, and its purpose is to make it possible to reliably convey even thick-walled and large-sized cutting chips, and to provide a simple and robust structure for this purpose. An object of the present invention is to provide a novel chip conveyor that can transport chips.

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a guide member arranged on the soil surface of the bottom wall of the conveyance path to maintain the movement of the reciprocating rod in a straight line, and a guide member provided on the inner surface of both side walls of the conveyance path. A plurality of holding parts □ members protruding inward on the transport direction side, a plurality of plate-shaped extruded members that increase the height on the transport direction side, and a plurality of holding parts □ members are arranged in rows on the top and both sides of the reciprocating rod, respectively; These push-out members are comprised of a hook part and a diagonal relief part formed at the front end and the back part, respectively, and are substantially perpendicular to the conveying direction.

EXAMPLE Hereinafter, an example embodying this invention is shown in FIGS. 1 to 1.
This will be explained based on Figure 0.

As shown in FIG. 1, a conveyance path 1 having a substantially U-shaped cross section is arranged under the table of various machine tools for cutting large workpieces, and the upper surface of the starting end thereof is covered by a top plate 2. A known power cylinder 4 connected to a drive motor 3 is installed in the conveyance path 1 below the top plate 2, and as the drive motor 3 is driven, the cylinder rod 5 is moved along the conveyance path 1 by the action of a screw. It appears and disappears in the horizontal direction above the bottom wall 1a. A horizontal drive unit protection cover 8 is attached to the front end of the cylinder rod 5 via a connecting member 6.
The upper horizontal portion 8a is slidably supported on a guide rail 7 provided on the inner surface of the side wall 1b of the conveyance path 1. Further, a reciprocating rod 9 made of a steel pipe and extending over almost the entire length of the conveying path 1 is connected to the front end of the cylinder rod 5 at one end via the connecting member 6.

As shown in FIG. 3, two bottom plates 10 having the same width and extending from the front end of the power cylinder 4 toward the terminal end of the conveyance path 1 are laid on the top surface of the bottom wall 1a5 of the conveyance path 1. A rail plate 11 serving as a guide member is erected and fixed between the bottom plates 10, the upper end of which is fitted into a slit 9a formed on the lower surface of the reciprocating rod 9, and which extends in a straight line with approximately the same length as the reciprocating rod 9. has been done. At the upper end of this rail plate 11, a large number of guide rings 1 are arranged at equal intervals (see Fig. 1).
2 are fixed, and the reciprocating rod 9 is supported from inside by these guide rings 12. As the power cylinder 4 is driven, the reciprocating rod 9 moves each guide ring 1.
2 in a straight line with a predetermined stroke.

As shown in FIGS. 1, 2, and 3, the forward rod 9
On the top of the power cylinder 4, a top extrusion piece 14 made of hardened iron and having a substantially right-angled plate shape is placed at a predetermined interval (in this embodiment, the distance is set to one half of the extension/contraction stroke of the power cylinder 4). Many are welded and fixed in an upright position. As shown in FIG. 5, the front end of each top extrusion piece 14 is formed with a hooking part 15 that is approximately perpendicular to one direction of the conveyance 6, and the back part has a gently recessed part that descends from the front to the rear. The arcuate relief portion 16 is formed diagonally.

In addition, on the outer surface of both sides of the reciprocating rod 9 at positions corresponding to these top extrusion pieces 14, there are a pair of left and right side extrusion pieces that are made of the same material as the top extrusion pieces 14 and are longer and have a substantially right triangular plate shape. 17 are welded and fixed in large numbers in a state facing downward at a predetermined angle (15° in this embodiment) from the horizontal direction. As shown in FIG. 4, each side extrusion piece 17
A hooking part 18 is formed at the front end of each of the carriages, which is substantially perpendicular to the conveyance direction, and a relief part 19, which is arch-shaped and gently recessed, is formed diagonally at the back of the carriage. ing.

The side extrusion piece 20 closest to the drive unit is welded and fixed downward at an angle (30° in this embodiment) that is larger than the inclination angle of the other side extrusion pieces 17, as shown in FIG. As such, its protruding end is close to the surface of the bottom plate 10.

On the other hand, as shown in FIGS. 2 and 3, on the inner surface of the side wall 1b of the conveyance path 1, there is a right-angled triangular plate corresponding to the forward and backward positions of the top and side extrusion pieces 14 and 17. A large number of holding pieces 22 in the shape of
It is protruded at an angle of . At the front end of each holding piece 22, a holding part 24 is formed at right angles to the side wall 1b of the conveyance path 1, and at the back thereof, a guide part 25 is formed obliquely.

Next, the operation of the chip conveyor configured as described above will be explained based on FIGS. 6 to 10.

Now, when the reciprocating rod 9 is reciprocated back and forth as the power cylinder 4 is driven with the cutting chips C being supplied into the conveyance path 1 from the bed surface of the machine tool, the reciprocating rod 9 is moved back and forth as shown in FIG. As shown in FIG. 2, the intertwined block-shaped cutting chips C are pushed forward in the conveyance path 1 by the hooking portions 15, 18 of the top extrusion piece 14 and the side extrusion piece 17. When the reciprocating rod 9 moves forward with a predetermined stroke (in FIGS. 6 to 10, the stroke is shown in accordance with the spacing of the holding pieces 22 for explanatory purposes), the cutting tip C
is guided by the guide part 25 of the front holding piece 22 and passes through the holding piece 22, and then, as shown in FIG.
It is latched by 4.

In this state, when the reciprocating rod 9 moves back, the cutting tip C is latched and held by the holding part 24, as shown in FIG.
7 pass through the cutting tip C by the action of the relief portions 16.19 provided on each side, and as shown in FIG. It is placed behind C. Therefore, when the reciprocating rod 9 is moved forward again in this state, the cutting tip C is held by the hook portion 15.18 of each extrusion piece 14.17, as shown in FIG.
is pushed further forward.

In this way, when the extrusion and latching operations described above are repeated with the reciprocating movement of the reciprocating rod 9, the cutting chips C in the conveying path 1 are sequentially conveyed toward the terminal end 9-, and are released into the air (not shown). It is released from the outlet into a chip collection box, etc. By the way, according to the chip conveyor of this embodiment, since the reciprocating rod 9 reciprocates in a straight line while being guided by the rail plate 11, the power cylinder 4 and the connecting member 6
No excessive force is applied to the parts, and damage to these parts can be prevented. In addition, since the top extrusion piece 14 and the side extrusion piece 17 provided on the reciprocating rod 9 are each formed in a plate shape, this kind of extrusion member is constructed in a box shape in order to widen the extrusion surface. In comparison, the structure is much simpler, and each extruded piece 14.17 receives the resistance of the cutting chips C that are entangled with each other in the conveyance path 1 and becomes a lump when the reciprocating rod 9 moves forward. There is little risk of damage and the cutting chips C can be transported reliably over a long period of time.Furthermore, if each extruded piece 14.17 is formed into a plate shape, the cutting chips C can be attached to the hooking portions 15.18 of the extruded pieces 14.17. It can also be given the ability to crush finely.

Furthermore, since the relief portions 16 and 19 of the top extrusion piece 15 and the side extrusion piece 17 are formed in a gently concave arch shape, the cutting tip C can be easily pulled out when the reciprocating rod 9 moves back. This allows the force acting on each holding piece 22 of the conveyance path 1 to be reduced. Furthermore, since each holding piece 22 is formed into a plate shape, even a thick and large cutting tip C can be reliably held and held during the return movement of the reciprocating rod 9, and there is little risk of breakage. Furthermore, if the side extrusion piece 20 closest to the drive unit is provided with its protruding end close to the surface of the bottom plate 10 as in this embodiment, the cutting chips remaining at the bottom of the drive unit side of the conveyance path 1 can be can be sequentially transferred to the front side.

It should be noted that the present invention is not limited to the configuration of the above-mentioned embodiment. For example, as shown in FIG. A large number of horizontal holding protrusions 27 projecting inward on the front side are provided on the inner surface of the side wall 1b, a holding surface 28 is formed at the front end of these holding protrusions 27, and an oblique guide surface 29 is provided at the back. may be formed so that each of these holding protrusions 27 can also convey granular or lump-like cutting chips. In addition, as shown in FIG. 12, depending on the size and shape of the cutting tip, a side extrusion piece 3O may be provided in an upward oblique manner, or as shown in FIG. 13, a pair of top extrusion pieces 31 may be provided. The pair of side extruded pieces 32 are formed to protrude obliquely toward the outside, and the pair of side extruded pieces 32 are formed to protrude horizontally, and as shown in FIG. The mounting position and inclination angle of each extruded piece with respect to the reciprocating rod 9 may be changed as appropriate, such as by forming the pair of side extruded pieces 33 in a downwardly inclined shape. In addition, top extrusion piece 14, side extrusion piece 17, and holding piece 2
The configuration of each part may be changed without departing from the spirit of the present invention, such as by arbitrarily changing the arrangement or shape of the parts 2 or arranging the conveyance path 1 at an angle so that the cutting chips C can be conveyed upward. It is also possible to embody it as follows.

Effects of the Invention As described in detail above, according to the present invention, a guide member for keeping the movement of the reciprocating rod in a straight line is arranged on the soil surface of the bottom wall of the conveyance path, and a front inner wall is provided on the inner surface of both side walls of the conveyance path. In addition to providing a holding member that protrudes in the opposite direction, a plate-shaped extruded member is provided on the reciprocating rod, and the extruded member has a hooking part and a relief part, so that it can be used for thick, large-sized, cutting, chipping, etc. However, it can be transported reliably, and the structure for this purpose can be easily and firmly constructed, which is an excellent effect.
