Description

  The present invention relates to an onion supply device for an onion skinning machine for supplying onion to a predetermined position in a rapid and continuous manner in an onion skinning machine.

  When the onion is peeled mechanically, the root core part and bud core part of the onion are removed, and then the skin is peeled off by blowing compressed air, and the root skin part and bud core part are removed simultaneously with the epidermis. A method is known in which a plurality of slits are inserted into the skin and then the skin is peeled off by blowing compressed air.

According to the former method, there is a drawback that peeling of the skin is insufficient and eventually the remaining skin is manually removed.
In the latter method, the onion is placed in a predetermined position, and the root core part, bud core part is removed and a slit is provided with a jig that descends from above the stationary onion. When the work is finished, the next onion will be put in place. Satisfaction can be obtained for peeling the skin, but the work efficiency is remarkably lowered, and it is sufficient in the place where a large amount of onion is used in the restaurant industry etc. Is not satisfactory, and the onion comes to be placed at the place where the jig descends, which causes a safety problem.

  The problems to be solved by the present invention are to eliminate the disadvantages of the conventional method, to ensure a quick and continuous treatment by laying off the onion, and to efficiently peel off a large amount of onion. It is intended to provide a supply device for the onion.

  In the present invention, as means for achieving the above-mentioned object, two chains that move at low speed are engaged in parallel with four gears arranged at an appropriate distance on the front and rear sides of the main body frame. -A large number of support plates having onion support holes are mounted on the chain at equal intervals. The support plate is formed of a rectangular plate, and the engagement holes formed at both ends of the plate are provided in the chain. A guide member having a semicircular arc guide surface at the front and rear ends of the main body frame and a guide surface of the guide member on both lower sides of the main body frame are detachably fitted to pins fixed on the top. A horizontal guide rail is provided so that the support plate is prevented from falling off the chain by the guide surface of the guide member and the guide rail, and further on the lower side of the support plate. There is a rotating roller that supports the support plate over an appropriate distance. B - is obtained so as to prevent the sinking of the support plate by la.

  In the apparatus of the present invention, the support plate on which the onion is placed is moved at a low speed in a certain direction by the rotation of the chain, and is sequentially supplied to the positions of the onion root removal member, the bud removal cutter and the slit application member. Therefore, the pre-treatment for peeling onion, that is, the removal of the root core and bud core, and the application of slits to the epidermis, can be performed automatically and quickly in a continuous operation, improving work efficiency significantly. In addition, there is an advantage that it can have an extremely great effect of enabling a large amount of onion to be peeled in a short time.

  Next, under the support plate, there is a rotation roller over an appropriate distance. This rotation roller supports the support plate, and pressure from above the root core removing member and the slit applying member. The root plate and bud core can be removed and the slit can be applied accurately and reliably without being submerged.

  Further, when the support plate is reversed with the rotation of the chain, both sides of the support plate are in contact with the guide surface of the guide member, so that the reversal can be smoothly performed and the guide plate is in the inverted state after the reversal. Since it comes in contact with the steel plate, the support plate does not fall off the chain, and the continuous supply of onions is guaranteed.

  A specific configuration of the apparatus according to the present invention will be described with reference to the drawings. FIG. 3 is a side view showing an outline of the entire apparatus, and includes a main body frame A, a root core removing member, a slit applying member, and the like. It consists of a working part B and a skin removing device C.

  Four gears 1 that are rotated by the power of the motor are arranged on both front and rear sides of the main body frame A. Two chains 2 are engaged with the gears 1 in a parallel state, and a rectangular plate A number of support plates 3 having onion support holes 4 are arranged on the chain 2 at equal intervals. A large number of pins 5 are fixed on the chain 2 at equal intervals, and the support plate 3 is detachably fitted to the pins 5 by engaging engagement holes 6 drilled on both sides of the support plate 3. It is attached to the chain 2.

  At the front and rear ends of the main body frame A, there is a guide member 7 having a semicircular arc guide surface 7a, and a horizontal guide rail 8 communicating with the guide member 7 is installed below the main body frame A. Yes. When the support plate 3 is reversed with the rotation of the chain 2, the both ends of the guide member 7 come into contact with the guide surface 7a of the guide member 7 and the support plate 3 is in an inverted state after the reversal. Is moved while in contact with the guide rail 8, and the support plate 3 does not fall off from the chain 2, and the support plate 3 can be moved smoothly.

  Next, on the lower side of the upper chain 2, a rotating roller 9 is laid over an appropriate distance, and this rotating roller 9 supports the support plate 3. The support plate 3 can withstand the pressure of the root core removing member and the slit applying member sufficiently and does not sink, and can accurately and reliably remove the root core portion and bud core portion and apply the slit. It will be.

  Thus, in the apparatus of the present invention, the onion D is placed in the support hole 4 of the support number 3 on the front side of the main body frame A in an inverted state (the root portion is up), and the support plate 3 is moved (low speed movement). When the onion D comes to the position of the root core removing member 10, the root core removing member 11 descends and scrapes the root core with the rotary blade 12, and at the same time, the sprout core installed below the support plate 3. The bud core is removed by the removal cutter 13, and then when the onion D reaches the position of the slit applying member 14, the slit applying member 14 descends to form a plurality of slits in the longitudinal direction with respect to the skin of the onion D. On the other hand, the onion D subjected to this pretreatment falls to the skin removing device C as the support plate 3 moves, and peels off the skin by the friction of the rotary roller and the pressure of the compressed air. The root core removing member 11 and the slit applying member 14 move slightly backward in synchronization with the transition of the support plate 3 during the removal of the root core and during the slit application, and ascend at the end of the work and return to the front. It becomes like this.
