Description

  The present invention relates to an onion automatic peeling apparatus that automatically and continuously peels an onion skin.

Conventionally, as an apparatus for removing the onion skin, there is a method in which compressed air is blown onto the onion from which the root core and bud core of the onion have been removed and the epidermis is removed with the pressure of the compressed air.
However, it is difficult to remove the sufficient skin with the pressure of the compressed air alone, and there are many parts to be left, and eventually the work of removing the skin from these left parts is necessary, which is inefficient and satisfactory. It was not a device.
Therefore, as a means for clearing the above-mentioned drawbacks, a device has been developed for slitting the epidermis simultaneously with the removal of the root and bud cores of the onion. One by one is manually placed, and the root core part, bud core part removal and slitting work are performed at the same location at once by a jig descending from above with respect to the onion.

  In this device, the onion is manually placed on a table, and after the root core portion, bud core portion removal and slitting operation are completed, the next onion is replenished, and a large amount of onion is used, for example, eating out In the case of industries, etc., there is a problem in work efficiency, and there is also a problem in safety because the onion is set directly under the jig.

  Thus, in order to eliminate the above-mentioned problems, the present invention allows the onion stand to move at a low speed in a certain direction in a conveyor manner, and the onion reaches the position of the root core removing member and the bud removing cutter. Sometimes the root core and bud core are removed, and then when the onion reaches the position of the slitting member, the slitting member is actuated to make a slit in the skin of the onion. The purpose is to provide a novel device that guarantees safety and high safety.

Means to solve the problem

  As a means for achieving the above-mentioned object, the present invention is a support plate of onion that moves at a low speed in a certain direction, and is located above and below the support plate and is moved up and down, and is arranged back and forth with a proper interval. An onion root removing member, a slit applying member for making a plurality of slits in the longitudinal direction with respect to the onion skin, and an onion arranged at a position corresponding to the root removing member below the support board A bud core removing cutter, which is placed in an inverted state in a circular support hole that opens in the onion support plate, and when the onion reaches the position of the root core removal member as the support plate moves, the root The core removing member descends and removes the root core portion of the onion. At the same time, the sprout removing cutter cuts out the sprouts of the onion. Next, when the onion reaches the position of the slit applying member, the slit applying member descends. A plurality of threads in the longitudinal direction with respect to the onion skin It was to put the Tsu door.

  Next, the onion support plate is arranged on two parallel chains that are engaged with gears arranged on both the left and right sides, and is formed on both sides of a rectangular plate having a support hole for the onion in the center. The joint hole is configured to be detachably engaged with a pin fixed on the chain, and the root core removing member of the onion is for suppressing the onion on the support plate at the lower end of the frame body that moves up and down. There is a pressing plate, and a reed blade of a root core that is rotated by rotation of the motor of the frame is detachably attached, and a root removal member is provided on the support plate while the reed blade of the root core is in operation. Synchronously with the movement, it moves slightly rearward, rises at the same time as the root turning operation is completed, and moves back to the front, and further, the slit applying member is on the center of the frame that moves up and down. There is a push bar to hold down the A slit arm is installed, and a slit blade is attached to the lower end of the slit arm, and the slit application member moves slightly backward in synchronization with the movement of the support plate during slit application to the onion skin. Then, it is raised at the end of the slit application work and moved back to the front.

The invention's effect

  The present invention places the onion in an inverted state (with the root core portion facing up) in the support hole of the onion of the supporting plate that moves at low speed, and when the onion reaches the position of the root core removing member by moving the supporting plate, The removal member descends and scrapes off the root core portion, and at the same time, the bud core is also excised by the bud removal cutter. Next, when the onion reaches the position of the slit application member, the slit application member descends against the onion skin. As a result, the onion in this state automatically falls to a predetermined location and the epidermis is peeled off by the pressure of the compressed air. It can be processed automatically and quickly in large quantities, and it is not only an extremely useful device when using a large amount of onions in the restaurant industry etc. at the same time, but also where the onions are placed Near removal member and slitting member Rather, it is obtained also highly safe because it is these distance-apart locations.

  In addition, the root core removing member and the slit applying member move rearward in synchronization with the movement of the onion during work (peeling of the root core portion, giving of the slit). Stripping and slitting can be performed accurately and neatly, and at the same time as the removal of the root core and the slitting, the root core removal member and the slit imparting member move forward and return to the next position. In this way, it is ensured that the flow work is performed repeatedly and continuously.

The specific configuration of the present invention will be described with reference to the drawings. FIG. 1 is a side view of an apparatus showing the main part of the present invention, and FIG. It is.
The onion support board 1 is an array of a large number of rectangular plate bodies 2 having onion support holes 3, and the chain 5 is parallel to the four gears 4 arranged on the front and rear sides of the main body frame A. A large number of pins 6 are fixed on the chain at equal intervals, and engaging holes 7 formed on both sides of the plate body 2 are engaged with the pins. It is also possible to provide a plurality if necessary, in this case, the root core removal member, bud removal cutter, and slit application member to be described later will be arranged in a number corresponding to the support hole 3 of the onion, A bud removal cutter 8 having a blade on a saw blade is installed at a position corresponding to the root removal member below the support board 1.

  Next, on the outside of the gear 4, a drop-off prevention member 9 that draws an arc shape for preventing the plate body 2 from dropping off when the support plate 1 is reversed and a rail 10 for preventing the drop-off are installed on the lower side. When the plate body 2 of the support plate 1 on the chain 5 is reversed from the upper side to the lower side, it moves along the drop-off prevention member 9 so that it does not fall off from the pin 6, and the plate body 2 is on the lower side. When it shifts to, it is supported by the rail 10, and similarly it is surely shifted to the upper part without falling off from the pin 6.

  Thus, at a position above the support plate 1, a root core removing member 11 and a slit imparting member 12 are suspended from the front side and the rear side at a slight distance. When the onion moves to a predetermined position, it goes down to remove the root core portion of the onion and make a slit in the onion skin.

  The root core removing member 11 includes a small motor 15 on a frame body 14 that is moved up and down by an air cylinder 13, a scissors blade 16 that is rotated by the motor 15, and an onion stamp frame 18 that receives the elastic pressure of a spring 17. In addition, the slit applying member 12 includes an onion push bar 21 that receives the spring pressure of a spring 22 on a frame 20 that is moved up and down by an air cylinder 19, and a plurality of slit arms 23 and a lower end in a state surrounding the push bar 21. There is a slit blade 24, and a spring 25 is interposed between the frame 20 and the slit arm 23 so as to constantly bias the slit arm 23 downward.

  The root core removing member 11 and the slit providing member 12 are connected to a push arm 28 that moves forward and backward by a lever 27 that swings left and right by the action of an eccentric cam 26, and moves slightly forward and backward by the push arm 28. The eccentric cam 26 and the gear 4 are rotated by a motor 29.

  The apparatus according to the present apparatus places the onion B in an inverted state (with the root portion facing upward) in the support hole 3 of the support board 1 that moves at a low speed in front of the main body frame A, and moves the onion B as the support board 1 moves. First, when the root core removal member 11 comes down, the root core removal member 11 descends and the press frame 18 presses the upper surface of the onion. At the same time, the scissors blade 16 rotates and the root core portion is rolled into a mortar shape. The shoot core removing cutter 8 removes the shoot core. At this time, since the support plate 1 continues to move even when the scissors blade 16 is in operation, the root core removing member 11 is also moved backward in synchronization therewith. When the removal of the root core part is completed, the root core removal member rises and moves forward. Since the plurality of rotating rollers 30 attached to the lower side of the support board 1 receive the pressing of the root core removing member against the onion, the onion does not sink, and a smooth root removal operation can be performed. .

  When the onion from which the root core part and the bud core part have been removed comes directly under the slit applying member 12, the slit applying member 12 descends and the push bar 21 presses the onion at the same time as the slit blade 24 of the slit arm 23 is the skin of the onion. On the other hand, a plurality of slits are inserted in the vertical direction. In this case, the support plate 1 continues to move, so that the slit applying member 12 moves slightly in synchronization therewith, and the slit applying is completed. At the same time, the slit applying member 12 moves up and returns while moving upward.

  The onion B, which has been subjected to the removal of the root core part and the bud core part in the above-described process and applied with the slit, falls onto a rotating roller installed at a predetermined position, and the compressed air is blown onto the rotating onion. The outer skin is peeled off by the pressure and the rotational friction of the rotating roller.
