Description

  The present invention relates to a cutting device for moths (including sweet potatoes such as Golden Senuki and Murasaki potatoes, potatoes, yam, etc.).

  If the size of the moss used in food factories is more than a certain size, the inside may be damaged even if the outside is normal, or uniform cooking may not be possible. For this reason, the sardines of a certain size or more have been selected by the operator from the conveyor, cut by a knife, removed the damaged part, and then returned to the conveyor. However, the size of the moss selected by the operator for cutting varies, and the severing operation of the moss by the operator has a problem that the work load increases because the moss is hard. Then, labor saving using the cutting device (for example, patent document 1) of moss was examined.

  Patent Document 1 discloses means (corresponding to a cutting device) capable of intermittently cutting an organic hydrated substance as a component of a processing system for the organic hydrated substance. The cutting device disclosed in Patent Document 1 has a configuration in which a slit is formed in a guide path for guiding a workpiece from a hopper to a conveying unit, and a rotary blade is intermittently passed through the slit. Accordingly, the size of the workpiece passing through the guide path is made uniform, and for example, uniform heat treatment can be performed (Patent Documents 1 to [0039] to [0042]).

JP 05-236923 A

  The cutting device for moss only needs to be able to cut only moss having a certain size or more. However, since the cutting device of Patent Document 1 cuts moss having a size less than a certain size that has passed through the guide route, it cannot be used as it is. Moreover, since the cutting apparatus of patent document 1 fixes the position of a workpiece relatively with respect to a rotary blade, it is thought that the pipe which has a cross section equivalent to a workpiece is used for a guidance path | route. However, this makes it difficult to cut many workpieces at once. Therefore, a cutting apparatus that can cut many moss of a certain size at a time was examined.

  What has been developed as a result of the study is a sorting mechanism that sends only moss of a certain size or more to the path of movement of the moss upstream of the path of movement of the moss (for example, conveyor) of the cutting mechanism for cutting the moss. The sorting device includes a plurality of taper rollers aligned in the same direction, each rotating shaft being arranged in parallel, and rotating from the large-diameter side of the rotating taper roller. Among the thrown-in pots, the pots of a certain size or more that did not fall from the gap between the tapered rollers are sent out from the small diameter side to the path of movement of the pots.

  The cutting device of the present invention includes a sorting mechanism upstream of the movement path of the moss constituting the cutting mechanism. The sorting mechanism of the present invention includes, for example, a taper roller that feeds potatoes introduced from the large diameter side to the small diameter side. For example, the bowl is introduced to the large diameter side of the tapered roller. The rods move from the large diameter side of the taper roller to the small diameter side while rolling along the side surface of the rotating taper roller. Then, only mosses having a certain size or more that have not fallen from the gap between the tapered rollers are sent out from the small diameter side to the mosquito's moving path, and the moss can be selected.

  The sorting mechanism is characterized in that the taper rollers having a taper angle of 0.5 to 6 degrees are arranged side by side with their respective rotation axes horizontal. When the taper angle of the taper roller is less than 0.5 degrees, the rods do not move from the large diameter side to the small diameter side. Further, when the taper angle of the taper roller exceeds 6 degrees, the moss rolls and jumps, and the tiny moss that should fall from the gap between the taper rollers is sent out from the small diameter side, so that the ware cannot be selected. If the rotation axis is leveled, smooth movement of the moss by the specified taper angle is ensured.

  The sorting mechanism may support the end of the rotating shaft of the tapered roller on a pedestal via a bearing base. The bearing stand moves the end of the rotating shaft of the taper roller away from the gantry and eliminates the possibility that the waste discharged from the small diameter side of the taper roller hits the gantry and stays there. Since the rotary shaft end on the large diameter side of the taper roller does not have the possibility of stagnation, it may be supported directly on the gantry, or may be supported on the gantry via the bearing table in the same manner.

  The cutting mechanism may be configured to raise and lower the blade to cut the rod on the movement path of the rod, and the blade may traverse the movement path of the rod. Since the blade has a width that traverses the movement path of the moss and moves up and down, the worm can be cut in the entire width direction of the movement path of the moss. The blade crosses perpendicularly or obliquely to the movement path of the moss, and the crossing form may be linear or curved. The cutting mechanism is configured to lift and lower the blade to cut the rod on the movement path of the rod, and includes a lifting mechanism (including a lifting drive source and a motion transmission mechanism) that lifts and lowers the blade. It is characterized by being arranged above the movement path. The lifting drive source can be exemplified by an electric motor, and the motion transmission mechanism can be exemplified by a crank mechanism.

  In addition, the cutting mechanism is configured to rotate the blade and cut the rod that flows through the movement path (for example, chute) of the porridge, and the rotation axis of the blade is arranged orthogonal to the movement path of the porridge. The blade may be rotated so as to cut the moss flowing through the movement path of the moss, and there may be a plurality of the blades, which may be arranged above and below the movement path of the moss.

  The cutting device of the present invention sorts many kinds of moss at once by a sorter, cuts many kinds of moss at a time by a cutting mechanism, and increases the throughput of the kind of moss to be cut as a whole, thereby improving the efficiency of the cutting work. Improve. If the taper roller has a taper angle of 0.5 ° to 6 ° and the rotation axis is horizontal, it will smoothly move foods of a certain size or more, and the foods of less than the above size will be removed between the taper rollers. It is possible to reliably sort the moss by dropping it from. If the rotation shaft end of the taper roller is supported on the gantry via the bearing pedestal, the gantry will not interfere with the discharge of potatoes, and many moss can be smoothly fed to the cutting mechanism. When the blade moves up and down across the movement path of the moss, it can cut a large amount of moss at once in the entire width direction of the movement path of the moss. By disposing the drive transmission mechanism above the movement path of the moss, the cleaning operation after use can be facilitated. In addition, the blade can be cut continuously by cutting the moss flowing through the movement path of the moss by rotating the blade. In addition, there are multiple blades and they are arranged above and below the movement path of the moss, so that it is difficult for the moss to jump upward from the movement path of the moss, and the load on the blade is distributed to efficiently distribute the moss. Can be cut.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the cutting device 1 to which the present invention is applied is configured so that only upstream-sized conveyors 211a have a certain size or larger upstream of the upstream conveyor 211a of the cutting mechanism 21 that cuts the vertical-shaped foods. It is configured to include a sorting mechanism 11 that feeds out to the head. The cutting device 1 can also be configured by combining a cutting mechanism 31 and a sorting mechanism 11 of another example described later. The conveyors 211a and 211b of this example, which are the movement paths of the moss, are separated into an upstream side near the sorting mechanism 11 and a downstream side where the blade 212 is lowered. The upstream conveyor 211a is configured as an upward gradient so that potatoes sent from the sorting mechanism 11 do not roll down to the downstream conveyor 211b. In this example, one conveyor 211a and 211b are provided, but a plurality of conveyors 211a and 211b may be provided. Further, the food may be sent directly from the sorting mechanism 11 to the downstream conveyor 211b.

  As shown in FIG. 2 (FIG. 2 does not show the chain 123) to FIG. 5, the sorting mechanism 11 has three taper rollers 111 aligned in the same direction and their rotation shafts 1114 aligned in parallel. It is a configuration. The potatoes are thrown into the large-diameter side 1112 of the tapered roller 111 by the feeding chute 114 and are sent to the small-diameter side 1113 by the tapered roller 111. The pots of a certain size or more that have not fallen from the gap 112 of the taper roller 111 are sent out from the small diameter side 1113 to the upstream conveyor 211a.

  If the throwing angle of the throwing chute 114 is large, there is a risk that the pottery thrown on the taper roller 111 will roll over and may not be sorted. For example, a curtain or the like is provided at the outlet of the throwing chute 114 to increase the momentum of the pottery. It is good to reduce. The side cover 115 is a plate surface provided on the left and right sides of the gantry 113 so as to sandwich the taper roller 111, and prevents spillage from the throwing chute 114 onto the taper roller 111 from spilling out of the gantry 113. The collection chute 116 is a funnel-like shooter that collects and drops small mosses that have fallen from the gap 112 of the tapered roller 111 at a specific position.

  The three tapered rollers 111 in this example have a truncated cone shape with the same outer diameter on the large diameter side 1112 or the small diameter side 1113 and the same taper angle. The plurality of taper rollers 111 may have different outer diameters on the large-diameter side 1112 or the small-diameter side 1113, and provide a difference in the respective taper angles. In this case, the different taper angles may be within a range of 0.5 to 6 degrees, preferably 1 to 3 degrees.

  In the taper roller 111, bearings 117 provided at the ends of the rotation shaft 1114 are supported by the pedestal 113 via the bearing base 118. The bearing stand 118 is provided with a long hole 119 extending in the direction in which the tapered rollers 111 are arranged. The taper roller 111 changes the size of the sort to be selected by changing the position at which the bearing stand 118 is bolted to the mount 113 within the range of the long hole 119 and adjusting the gap 112 between the adjacent taper rollers 111. it can. The taper roller 111 can also adjust the gap between the adjacent taper rollers 111 by changing the position where the bearing stand 118 is bolted to the mount 113 within the range of the long hole provided in the mount 113.

  The bearing stand 118 on the small diameter side 1113 keeps the end of the rotating shaft 1114 on the small diameter side 1113 away from the pedestal 113, thereby avoiding a situation in which the rods sandwiched between the gaps 112 of the taper roller 111 hit the pedestal 113 and cannot be sent out. The bearing stand 118 on the large diameter side 1112 is provided to level the rotating shaft 1114 of the taper roller 111.

  The tapered roller 111 has a driven sprocket 122 attached to the end of the rotating shaft 1114 on the large diameter side 1112. The roller drive source 120 supported by the gantry 113 has a drive sprocket 121 attached to the rotating shaft 125. The drive sprocket 121 and the driven sprocket 122 are rotated in the same direction as the chain 123 is wound around. The chain 123 is pressed by a guide roller 124 supported by a gantry 113 to prevent slack.

  The sorting mechanism 11 sorts the moss according to the following procedure. The potatoes are supplied to the upper end of the inclined charging chute 114 (arrow a in FIG. 2), and the moss is introduced closer to the large diameter side 1112 of the tapered roller 111 (arrow b in FIG. 2). The potatoes move from the large diameter side 1112 to the small diameter side 1113 of the tapered roller 111 along the side surface of the rotating tapered roller 111 (arrow c in FIG. 2).

  Naturally, the moss falls if it is smaller than the gap 112 of the tapered roller 111 (arrow d in FIG. 2) and is collected through the collection chute 116. The small moss collected in this way is confirmed by the operator as it is, and if there is no problem, it is sent to a subsequent process (for example, a steaming process). On the other hand, potatoes which are larger than the gap 112 on the small diameter side 1113 and have not fallen from the gap 112 are sent from the small diameter side 1113 to the upstream conveyor 211a (arrow e in FIG. 2).

  In the configuration in which the blades 212 of the cutting mechanism 21 are moved up and down to cut the ridges on the conveyor 211b, FIGS. 6 to 10 (FIG. 8 omits the side plate 221 and the base 214, and the downstream conveyor 211b). As can be seen, the blade 212 is moved up and down by the lifting mechanism 222 to cut the potatoes on the transport surface 2111 of the downstream conveyor 211b. In this example, three blades 212 having a width that intersects the conveyance surface 2111 perpendicular to the conveyance direction of the downstream conveyor 211b are suspended from the blade support portion 213. Each of the blades 212 may be slightly inclined in the conveyance direction of the downstream conveyor 211b (−10 degrees to +10 degrees). One or more blades 212 may be used, but a plurality of blades 212 is preferable because it can cut more potatoes while suppressing the frequency of raising and lowering, and work efficiency is improved.

  The blade support portion 213 includes a flat blade support base 2131 having guide bar receivers 217 attached to four corners, and a blade support plate 2132 arranged on the lower surface of the blade support base 2131. The blade support plate 2132 is composed of a pair of sandwiching plates orthogonal to the transport direction of the downstream conveyor 211b. Three sets of the clamping plates are arranged in parallel in the transport direction at equal intervals, and each is clamped with a blade 212 therebetween. Thus, the three blades 212 are arranged in parallel at equal intervals in the transport direction of the downstream conveyor 211b.

  The downstream conveyor 211b receives an impact from which the moss falls from the upstream conveyor 211a and a pressure when the lowered blade 212 cuts the moss. For this reason, the downstream conveyor 211b is preferably a rubber belt conveyor having both strength against impact and pressure and stretchability. In the downstream conveyor 211b of this example, a side plate 221 is attached to the upper surface of the support base 215 and the side surface of the blade 212 to prevent the bowls from falling from the transport surface 2111. In addition, the side plate 221 may be provided with a bar or plate that protrudes toward the side surface of the lowered blade 212, and the bowl that adheres to and lifts the blade 212 may be dropped onto the transport surface 2111 of the downstream conveyor 211b. it can.

  The blade 212 ascends and descends toward the conveying surface 2111 of the downstream conveyor 211b according to the ascending / descending motion of the blade support portion 213. The raising / lowering amount of the blade 212 is set so that the distance between the tip of the blade 212 and the conveyance surface 2111 of the downstream conveyor 211b is about 1 mm to 5 mm. As a result, the food on the transport surface 2111 of the downstream conveyor 211b can be cut, but since the tip does not collide with the transport surface 2111, the downstream conveyor 211b is not damaged.

  The raising / lowering mechanisms 222 that raise and lower the blades 212 are all disposed above the downstream conveyor 211b. Thereby, the raising / lowering mechanism 222 does not have a possibility of becoming dirty by dropping of trash and the like. The motion transmission mechanism of this example is a crank mechanism including a crank disk 2227 and a rod 2228. The lifting drive source 2221 is fixed on the drive source base 218. The drive source base 218 is supported by a guide bar 216 fixed to a support base 215 at the top of the base 214.

  If the raising / lowering drive source 2221 is an electric motor with a brake, for example, the advantage that the state where the blade 212 is lifted during maintenance can be maintained. The elevating drive source 2221 has a drive sprocket 2223 attached to the drive side rotating shaft 2222. The drive source base 218 is provided with a bearing base 220 at the top. The bearing stand 220 supports the bearing 219 of the driven side rotating shaft 2226. The driven rotary shaft 2226 is attached with a crank disk 2227 at both ends and a driven sprocket 2224 inside the bearing 219. The driven side rotation shaft 2226 is rotated by a chain 2225 that is wound around the drive sprocket 2223 and the driven sprocket 2224 to rotate the crank disks 2227 at both ends.

  The crank disk 2227 is connected to the blade support portion 213 by a rod 2228. The motion transmission mechanism converts the rotational motion of the crank disk 2227 into the lifting motion of the rod 2228 and transmits the lifting motion to the blade support portion 213. The blade support part 213 moves up and down in the vertical direction while the guide bar receivers 217 attached to the four corners are restrained by the guide bar 216. Thus, the blade 212 supported by the blade support portion 213 is lifted and lowered stably in the vertical direction by the lifting and lowering movement of the rod 2228. The arrangement and number of the guide bars 216 are not limited as long as the blade support part 213 can be moved up and down stably.

  11 to 12, the cutting mechanism 31 of another example rotates the rotating shaft 314 of the blade 312 by the driving source 315, and cuts the chute 311 that flows in the direction of arrow e in FIG. . When the chute 311 is used as a transport path for the moss, a driving means for moving the moss is not necessary. The chute 311 and the drive source 315 are supported by the gantry 316. The inclination of the chute 311 and the arrangement and number of blades 312 are not limited, and may be adjusted as appropriate depending on the target processing capacity, cutting position, and number of cuttings. As another example, as shown in FIG. 12, a blade 312 in a vertically standing posture is disposed in the left and right center in the vicinity of the chute outlet 3111, and the rods are cut almost at the left and right center.

  The blade 312 includes a blade (upper part) 3121 and a blade (lower part) 3122 arranged above and below the chute outlet 3111. The chute 311 has a notch 317 for projecting the blade (lower part) 3122. When viewed from the front in FIG. 11, the blade (upper part) 3121 is clockwise (arrow f in FIG. 11), and the blade (lower part) 3122 is counterclockwise (arrow g in FIG. 11). Since the moss flowing through the chute 311 is cut while being sandwiched between the blade (upper part) 3121 and the blade (lower part) 3122, it is difficult to jump out upward from the chute 311, particularly upward from the chute outlet 3111. Moreover, the load at the time of a cutting | disconnection is disperse | distributed to the blade (upper part) 3121 and the blade (lower part) 3122, and can cut | disconnect potatoes efficiently.

  The gap 313 between the blade (upper part) 3121 and the blade (lower part) 3122 is preferably about 2 to 10 mm. If the gap 313 is in the above range, the barb can be completely cut right and left while eliminating interference between the blade (upper part) 3121 and the blade (lower part) 3122. In addition, if at least one of the blade (upper part) 3121 or the blade (lower part) 3122 is a tip saw having a tip attached to the blade tip, it becomes easy to stably cut the potato without slipping on the cutting surface of the potato. ,preferable. The rotational speeds of the blade (upper part) 3121 and the blade (lower part) 3122 may be the same or different.
