And a drive pinion gear that is meshed with the rack of the hand push lever, and a drive that is provided on one side of the drive pinion gear and that is engaged with the engagement portion of the drive shaft so that the drive shaft can rotate. It consists of nails.

  The engaging portion is formed by a pin penetrating the drive shaft so as to engage the drive claw of the drive pinion gear.

  A positioning plate is provided at the end of the drive shaft to restrict the drive shaft so that the drive shaft can be stopped at the 180 ° forward / reverse rotation position.

  The positioning plate is provided with stop holes at 180 ° intervals on the inner peripheral surface, and the protruding ball on the front end of the plunger, which is spring-biased on the stationary support plate, is engaged with the stop hole. (Drive shaft) was fixed.

  The engagement portion includes an automatic flip-up ratchet mechanism that releases engagement with the drive portion and returns to a fixed position at every predetermined rotation pitch of the drive shaft.

  The drive unit includes a drive gear pivotally attached to one end of the drive shaft so as to be freely rotatable and a hand lever provided with a lever gear meshing with the drive gear and capable of reciprocatingly swinging via a return spring.

  The automatic flip-up ratchet mechanism includes a drive crank that floats on a drive shaft, and a plurality of drive plates that are connected to one end of the drive crank via a first drive link and a second drive link and are integrated with the drive shaft. A driving roller that can be engaged with the stopper groove and a driving lever that is integrated with a driving gear that is rotated by a hand pushing operation of the hand pushing lever, and through the swinging action of the driving lever by the hand pushing action of the hand pushing lever, The drive roller is engaged with any one of the plurality of stopper grooves of the drive plate, and the power of the drive gear can be transmitted to the drive plate by the drive roller.

  A plurality of the food hoppers are provided in parallel.

  According to the present invention, it is possible to accurately supply the food by making it possible to obtain appropriate rotation speeds for the rotary basket and the stirring mechanism in the dry food metering / dividing apparatus.

  That is, the present invention includes an engagement portion provided on the drive shaft, and a drive portion that engages with the engagement portion and rotates the drive shaft, and the drive shaft is provided at the end of the drive shaft. With a positioning plate that can be controlled so that it can be stopped at the 180 ° forward / reverse rotation position, an appropriate rotation speed can be obtained for each of the rotary rod and the stirring mechanism, and an accurate food supply can be achieved. In the food supply state in which the hole is positioned below, a so-called one-feed state in which the food is supplied to the hole above the rotary rod is accurately obtained. Further, by turning this upside down by the stirring mechanism arranged in the food hopper, foods having irregular sizes can be stably supplied at a substantially constant ratio. In addition, this stirring mechanism can prevent clogging of foodstuffs in the food hopper.

  As a more specific configuration, the drive unit is disposed adjacent to the drive shaft so as to be capable of reciprocating up and down via a return spring, and has a hand-lever provided with a rack along the longitudinal direction, A drive pinion gear mounted on the drive shaft so as to be freely rotatable and meshed with the rack of the hand push lever, and provided on one side of the drive pinion gear, and engaged with an engagement portion of the drive shaft.

  Since the engaging portion is formed by a pin penetrating the drive shaft so as to engage the drive claw of the drive pinion gear, the pin is pressed at one point by the drive claw, and therefore, the rotary rod, The contact friction between the driving claw and the pin when the stirring mechanism is rotationally driven is reduced.

  Furthermore, the positioning plate is provided with stop holes at 180 ° intervals on the inner outer peripheral surface, and the protruding ball on the front end of the plunger that is spring-biased provided on the stationary support plate is engaged with the stop hole. Since the positioning plate (drive shaft) is fixed, when the plunger's projecting ball engages with the stop hole of the positioning plate, the positioning plate (drive shaft) clicks into place at the specified position. It can be easily confirmed that the engagement has been made.

  Further, since the engaging portion includes an automatic flip-up ratchet mechanism that releases the engagement with the driving portion and returns to a fixed position at every predetermined rotation pitch of the driving shaft, An appropriate rotation speed can be obtained and accurate dry food can be supplied. In the dry food supply state in which the hole of the rotary basket is located below, the dry food is supplied to the hole above the rotary basket. A so-called single feed state can be obtained accurately. Moreover, by turning this upside down by the stirring mechanism arranged in the food hopper, dry foods having irregular sizes can be stably supplied at a substantially constant ratio. In addition, this stirring mechanism can prevent the clogging of the dried food in the food hopper.

  As a more specific configuration, the drive unit includes a drive gear pivotally attached to one end of the drive shaft so as to be freely rotatable, and a lever gear that meshes with the drive gear, and can be manually reciprocated via a return spring. Since it is composed of a lever, a mechanism for obtaining an appropriate rotation speed for each of the rotary rod and the stirring mechanism can be manufactured easily and at low cost.

  The automatic flip-up ratchet mechanism includes a drive crank that floats on a drive shaft, a drive plate that is connected to one end of the drive crank via a first drive link and a second drive link, and is integrated with the drive shaft. A drive roller that can be engaged with a plurality of stopper grooves, and a drive lever that is integrated with a drive gear that is rotated by a hand pushing operation of the hand pushing lever. Since it is engaged with any one of the plurality of stopper grooves of the drive plate and the power of the drive gear can be transmitted to the drive plate by the drive roller, each of the rotary rod and the stirring mechanism via the drive shaft A predetermined angle rotation operation can be obtained with certainty, and it can be driven quietly without a clicking sound between the drive roller and the stopper groove during the rotation operation.

  Since the engaging portion is formed by a driving roller that is engaged with a stopper groove of the driving plate of the driving shaft so that the driving shaft can be rotationally driven, the driving roller is pressed at one point by the stopper groove of the driving plate. Therefore, the contact friction between the driving roller and the stopper groove when the rotary rod and the stirring mechanism are driven to rotate is reduced.

  Since a plurality of the food hoppers are provided in parallel, for example, a plurality of types of foods such as dried soup and miso soup can be metered and supplied at the same time.

The best mode for carrying out the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the dry food metering / dividing device according to the present invention is substantially L-shaped at a substantially central position in a rectangular box-shaped food hopper 1 a, 1 b having an opening 2 whose lower side is gradually tapered.

I'm allowed. In the rotary rod 4, dry food is supplied to the upper hole in a state of supply of food with one hole positioned below by an operation of the driving unit 10 described later or an operation of the automatic flip-up ratchet mechanism P described later. The so-called single feed operation is obtained.

  As shown in FIG. 2, the food hoppers 1 a and 1 b are arranged in parallel on the front and rear portions in one side with the rotary rod 4 and the stirring mechanism 3 on one side surface of the casing 11 that forms the drive unit 10. They are connected to each other via a connecting screw 1c. For example, one of the ingredients hopper 1a is supplied with dried seaweed, and the other ingredient hopper 1b is supplied with dried leek, and each opening 2 Through these, a predetermined amount of these dry ingredients are supplied to the lower tray 6.

  In addition, in this form, although the 2 type food hopper 1a, 1b is provided, it is not restricted to this, A 1 type, a 3 type, a 4 type, etc. may be sufficient. For example, when three or more food hoppers 1a, 1b,... Are connected to the outer surface of the casing 11 with respect to the drive unit 10 in the casing 11, the drive shaft 5 itself can be replaced with a long one. An intermediate portion of the drive shaft 5 is a screwed connection structure. Further, each of the rotary rod 4 and the stirring mechanism 3 is configured to be detachable from the drive shaft 5.

  The drive unit 10 simultaneously rotates the stirring mechanism 3 and the rotary rod 4 in the vertical position through the respective drive shafts 5. For example, a pin is perpendicular to the axial direction of the drive shaft 5 (diameter direction). ), And an engaging claw 28 (to be described later) of the driving unit 10 is engaged with the engaging unit 27 to rotate the drive shaft 5.

  That is, as shown in FIG. 3 and FIG. 4, the drive unit 10 has a U-shaped frame-like frame that stands up in the casing 11 by inserting a bar-shaped hand pushing lever 12 having a knob 12 a at the upper end from the upper surface of the casing 11. The guide pins 14 that are horizontally mounted as a pair on both the upper and lower sides of the guide rail 13 are loosely fitted in the guide long holes 15 that are drilled along the longitudinal direction of the hand push lever 12 on the rack 17 side. 12, the rack 17 itself can be slid in the vertical direction. A return spring 16 is suspended between the upper surface of the casing 11 and the approximate middle of the hand push lever 12, and the hand push lever 12 itself can be reciprocated in the vertical direction via the return spring 16. Along with the longitudinal direction of the lower side of the hand lever 12, a long strip plate rack 17 is attached, and the upper and lower drives corresponding to the stirring mechanism 3 and the rotary rod 4 arranged adjacent to the hand lever 12 are provided. The pinion gears 25 are meshed with each other. Further, an upper stopper 18 is provided on the upper end side of the rack 17 of the hand pushing lever 12, and a lower stopper 19 is provided on the lower end side of the guide rail 13 in the casing 11.

Are rotated at the same time.

  As a result, the foodstuff is supplied to the upper hole of the rotary basket 4 while being stirred by the stirring mechanism 3, and the upper hole is reversed downward by the simultaneous rotation of the rotary cup 4, and the foodstuff is transferred from the opening 2 into the tray 6. Supplied. In this state, the foodstuff is simultaneously supplied into the hole directed upward of the rotary rod 4.

  Further, as shown in FIG. 7B, when the hand pushing lever 12 is integrated with the rack 17 and locked to the lower stopper 19, the plunger 23 protrudes into the stop holes 22 a and 22 b of the positioning plate 21. The sphere 24 is engaged, and the drive shaft 5 is stopped at the 180 ° forward rotation position.

  Then, as shown in FIG. 7C, when the hand push lever 12 is raised and returned together with the rack 17 by the return spring 16, the drive pinion gear 25 rotates in the reverse direction and is stopped at this time. The drive claw 28 escapes (overrides) with respect to the engaging portion 27 (pin) of the drive shaft 5 that is present.
