Description
104~963 This invention relates to a conveyor specially adapted for conveying machining waste or metal scraps from machine tools, such as, for example, a lathe or a drill. In one specific aspect, the present invention relates to a conveyor for such use in which the machining refuse or metal scraps are automatically conveyed under the action of a spiral carrier. In another aspect, the present invention i9 concerned with a conveyor for such use which is of thin and compact shape 80 as to be adapted for installation under the machine. In yet another aspect, this invention is concerned with a conveying hopper for such use with sides spread outwardly towards the outlet.
It i8 well known that troublesome work ls involved in dispos-ing of machining refuse or chips produced in bulk in a machine tool, such as, for example, a lathe or a drill. One common practice is to use an ordinary conveyor on which the refuse is carried away for discharge.
Among the difficulties, however, are that possibly tangled refuse becomes more and more bulky and remains unmoved on the conveyor. At the end of the conveyor, such bulky refuse must be shifted from the conveyor to a further transportation means by manpower. This work is both laborious and dangerous.
Another known conveyor for such machining refuse comprises an endless chain link extended vertically in relation to the machine. This necessitates a relatively large space for its installation, and a pit is usually made under the machine to receive the conveyor. This requires extra work, and once the pit is made it is difficult to move the machine from place to place. In addition, some refuse is likely to pile up in the pit from various kinds of machines, such as, for example, a lathe, a drill, a planer, etc.
Also used in con~unction with such conveyors are hoppers. One conventional hopper has sides sloping inwardly towards the bottom, in which a hole is provided for discharging the contents. A hopper of this shape is commonly used for receiving machining refuse for disposal out-side the machine; h~wever, difficulties are frequently encountered in . .
removing an entangled refuse fram the narrowed outlet. In such cases the refuse is likely to become a heavy lump within the hopper and suddenly to ~P therefrQm r An object of one broad aspect of this invention is to provide an improved conveyor capable of carrying such machining refuse under the action of a conveyor without excessive use of manpower.
An object of another aspect of this invention is to provide a conveyor of thin and compact shape in which the machining refuse is separately divided into different areas for future sorting out.
An object of still another aspect of this invention is to provide a conveying hopper in which such machining refuse is constantly and sm~othly ~moved away into the outlet. _ According to a broad aspect of this invention, a hopper is provided for disposing of machining refuse which comprises a hopper body having an inlet zone provided with an inlet end and an outlet zone provided with an outlet end, the outlet zone being angled from the inlet zone, the hopper body being provided with side walls which extend outwardly tcwards the outlet end of the outlet zone, so that the diameter of the outlet end is larger than the diameter of the inlet end, gate neans operatively associated ,with the outlet end for opening and closing the outlet end and at least one screw conveyor means rotatably disposed in the lower portion of the hopper in the outlet zone, the screw conveyor means being directed toward the outlet end of the hopper.
By a variation for aspect of the hopper of this invention, the h~pper body is mounted within a framew~rk so that the inlet end of the hopper is ~
disposed in a vertical position and the outlet end of the hopper is dis- _ posed dcwnwlrdly and at an angle from the vertical position.
By a variation of a further aspect of the hopper of this invention the hopper body is provided with a bottom floor and the screw conveyor is disposed in the bottom floor. _ By a variation of another aspect of the hopper of this invention, the gate means includes a pair of toothed racks disposed on opposite edge

Referring now to Figures 1 - 6, it is seen that machining ~r refuse is received in a trough 1 in which a screw 3 provided with helical r blades 2 is rotatably housed. The trough 1 is connected to a selected conveyor tube, either 5, 6, 7, 8 or 9, of various section as illustrated ~ ~, in Figures 4, 5, 6, 1 or 7, respectively. In Figure 1, the conveyor ~ -tube 8 is bent upwardly, whereas in Figure 2, the tube 9 is bent side- ' r ways; reference numerals 41 and 42 denote the discharges of the trough 1 and the conveyor tube 8 or 9, respectively. The conveyor tube 5 C~ ' r ' ~ 3a ~
`:~ `f lQ4~963 , illustrated in Figure 4 is of rectangular trough shape; the conveyor tube 6 illustrated in Figure 5 is cylindrical; and the conveyor tube 7 illustrated in Figure 6 is tapered, whether it be a rectangular trough-shaped or cylindrical.
The upwardly-bent conveyor tube 8 is supported by a pillar 10 with its discharge 42 facing a collector 11. Likewise, the conveyor tube 9, which is horlzontally supported, i8 appropriately connected to a collector (not shown).
This embodiment of this aspect of this invention thus fabri-cated is operated as follows:
When the screw 3 is rotated by a motor M, the received machin-ing refuse is carried by means of the blades 2 of the screw 3 and con-veyed into the tube 8 or 9, in which it piles up gradually. However, the refuse pile in the tube i8 pushed by freshly conveyed refuse and gradually moves towards the discharge 42. Finally the refuse is received into the collector 11. Since the machining refuse is forced to find its way by the screw 3, its pile in the tube is readily pushed and advanced towards the discharge. The screw 3 can be replaced by a rod capable of reciprocal movement. As evident from the foregoing the machining refuse can be transported to a collector without the use of manpower.
Referring now to Figures 7 - 10, a relatively thin slender box constitutes the body of a conveyor, generally indicated by reference numeral 101, in which an intermediate wall 102 is placed to divide the inside space into two sections. In each section there is provided a triangular base 103 constituting two passages 1041 and 142 for machining refuse to be carried in. The conveyor 101 is provided with an approp-riate number of beams 110 across its open end, over which a cover 130 is overlaid. A pair of channels 112 is fixed to the beams 110 with their open ends 111 directed downwards. In the cover 130 and the bottom floor 131 there are provided apertures 105 and 106, respectively, through which the refuse is put into and taken away. In the conveyor 101 there are provided a pair of sprockets 107 and 108, sprocket 107 being driven by ~041963 an electric motor (no~ shown). These sprockets 107, 108 entrain and convey an endless chain link 109, which is placed iD the open ends of each channel so as to be capable of its free running. The chain 109 includes upper link elementæ 113 and lower link elements 119 as best $11ustrated in Figure 3. In the upper link elements 113 there are pro-vided a pair of erected walls 113 in which a shaft 114 is supported.
The shaft 114 is provided with rollers 115 at is opposite ends, wherein the rollers 115 are rotatably stopped on the shaft by means of split pins 116. In this way a roller unit 117 is constituted. The rollers 115 are adapted to roll on rails 118, which are installed on the inside bent rims of the channel 112. Thus, when the chain link 109 is conveyed the roller unit 117 i~ caused to run the rail 118 within the channel 112.
The erected walls 113a are arranged at an appropriate interval. Between the ad~acent roller units 117 there i8 provided a pusher unit 123 in the lower link element 119 as best illustrated in Figure 3. The pusher unit 123 includes a pair of erected walls ll9a fixed in the lower link element 119, a pair of shafts 120 supported in parallel in the erected walls ll9a, a pair of arms 122 having a pusher 121, the arm being carried on the shaft 120 through a box 122a, and separators 125 carried on the shafts 120, which are stopped in the erected walls by means of split pins 124. In this way each pusher unit has a pair of pushers 121 as best illustrated in Figure 2. When the chain link 109 is conveyed by the sprocket 107, the pusher unit 123 is soved while the pusher 121 is caused to slide on the bottom floor, in the course of which the refuse inside is pushed and dropped into the outlet apertures 106. In this way the pusher units 123 are circulated throughout the conveyor 101, whereby the refuse piling up in each passage 104 is effectively cleared.
Turning now to Figures ll and 12, a hopper body 203 takes the form of a bent tube and is provided with an inlet 201 in one end and in the other end, an outlet 202. The inside diameter of the outlet 202 is larger than that of the inlet 201. The lower part of the hopper body 203 is housed within a framework 204. On the bottom side wall of the ;3 hopper there i8 provided a screw 207 including a rotatable axle 206 and blades 205,which is directed towards the outlet 202.
In the outlet 202 there is provided a gate 208 capable of being rai~ed to open the outlet 202. The gate 208 includes a pair of toothed bars or racks 209 in its opposite edge portions, which racks 209 engage with pinions 211 rigid with 8 rotatable shaft 210. Thus when the shaft 210 is rotated the gate 208 is raised or lowered under the guidance of a guiding frame 212 and rollers 213. Finally the raised gate 208 is housed within the guiding frame 212. The raising and lowering of the gate 208 can be effected by an electric motor (not shown).
In using the hopper, ~he gate 208 is closed, and the machining refuse is accumulated inside to the extent that some amount is stored therein. In accumulating it the screw 207 is rotated to help it piling up when it is needed. After the gate is opened, the piled-up refuse is taken away, with-or without the help of the screw 207. This is helped by the bent portion of the hopper 203 and the widened outlet 202.
By a variation of a still further aspect of the hopper of this invention, guide frame means and roller neans are provided for guiding the gate means during its raising and lowering operation.
By a variation of yet another aspect of the hopper of this invention the guiding frame extends above the outlet to the hopper body, the guiding frame housing the gate means in its raised position.
By a variation of another aspect of the hopper of this invention motor means are provided for raising and lowering the gate neans.

Referring now to Figures 1 - 6, it is seen that machining ~r refuse is received in a trough 1 in which a screw 3 provided with helical r blades 2 is rotatably housed. The trough 1 is connected to a selected conveyor tube, either 5, 6, 7, 8 or 9, of various section as illustrated ~ ~, in Figures 4, 5, 6, 1 or 7, respectively. In Figure 1, the conveyor ~ -tube 8 is bent upwardly, whereas in Figure 2, the tube 9 is bent side- ' r ways; reference numerals 41 and 42 denote the discharges of the trough 1 and the conveyor tube 8 or 9, respectively. The conveyor tube 5 C~ ' r ' ~ 3a ~
`:~ `f lQ4~963 , illustrated in Figure 4 is of rectangular trough shape; the conveyor tube 6 illustrated in Figure 5 is cylindrical; and the conveyor tube 7 illustrated in Figure 6 is tapered, whether it be a rectangular trough-shaped or cylindrical.
The upwardly-bent conveyor tube 8 is supported by a pillar 10 with its discharge 42 facing a collector 11. Likewise, the conveyor tube 9, which is horlzontally supported, i8 appropriately connected to a collector (not shown).
This embodiment of this aspect of this invention thus fabri-cated is operated as follows:

The screw 3 can be replaced by a rod capable of reciprocal movement. As evident from the foregoing the machining refuse can be transported to a collector without the use of manpower.
Referring now to Figures 7 - 10, a relatively thin slender box constitutes the body of a conveyor, generally indicated by reference numeral 101, in which an intermediate wall 102 is placed to divide the inside space into two sections. In each section there is provided a triangular base 103 constituting two passages 1041 and 142 for machining refuse to be carried in. The conveyor 101 is provided with an approp-riate number of beams 110 across its open end, over which a cover 130 is overlaid. A pair of channels 112 is fixed to the beams 110 with their open ends 111 directed downwards. In the cover 130 and the bottom floor 131 there are provided apertures 105 and 106, respectively, through which the refuse is put into and taken away. In the conveyor 101 there are provided a pair of sprockets 107 and 108, sprocket 107 being driven by ~041963 an electric motor (no~ shown). These sprockets 107, 108 entrain and convey an endless chain link 109, which is placed iD the open ends of each channel so as to be capable of its free running. The chain 109 includes upper link elementæ 113 and lower link elements 119 as best $11ustrated in Figure 3. In the upper link elements 113 there are pro-vided a pair of erected walls 113 in which a shaft 114 is supported.
The shaft 114 is provided with rollers 115 at is opposite ends, wherein the rollers 115 are rotatably stopped on the shaft by means of split pins 116. In this way a roller unit 117 is constituted. The rollers 115 are adapted to roll on rails 118, which are installed on the inside bent rims of the channel 112. Thus, when the chain link 109 is conveyed the roller unit 117 i~ caused to run the rail 118 within the channel 112.
The erected walls 113a are arranged at an appropriate interval. Between the ad~acent roller units 117 there i8 provided a pusher unit 123 in the lower link element 119 as best illustrated in Figure 3. The pusher unit 123 includes a pair of erected walls ll9a fixed in the lower link element 119, a pair of shafts 120 supported in parallel in the erected walls ll9a, a pair of arms 122 having a pusher 121, the arm being carried on the shaft 120 through a box 122a, and separators 125 carried on the shafts 120, which are stopped in the erected walls by means of split pins 124. In this way each pusher unit has a pair of pushers 121 as best illustrated in Figure 2. When the chain link 109 is conveyed by the sprocket 107, the pusher unit 123 is soved while the pusher 121 is caused to slide on the bottom floor, in the course of which the refuse inside is pushed and dropped into the outlet apertures 106. In this way the pusher units 123 are circulated throughout the conveyor 101, whereby the refuse piling up in each passage 104 is effectively cleared.
Turning now to Figures ll and 12, a hopper body 203 takes the form of a bent tube and is provided with an inlet 201 in one end and in the other end, an outlet 202. The inside diameter of the outlet 202 is larger than that of the inlet 201. The lower part of the hopper body 203 is housed within a framework 204.
