Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deformed product adsorption / transfer device for adsorbing and transferring articles having irregular shapes.

[0002]

2. Description of the Related Art Conventionally, the work of putting octopus roasted octopus into a baking die has been performed manually by workers even in the case of mass production in a factory, which is a major obstacle to improvement in productivity. It was a factor.

[0003]

When attempting to mechanize a work for supplying an odd-shaped object such as an operation of filling an octopus for octopus baking into a baking die, a promising means is to use an octopus (irregular shape in a hopper). It is conceivable to adsorb and transfer the material) and drop it on the mold, but it had the following problems.

For example, in the case of supplying octopus, if the suction nozzle is directly lowered in the hopper to suck the octopus, the descending distance of the suction nozzle must be changed according to the position of the octopus to be sucked. However, this complicates the device configuration and control. In addition, since the suction condition is not constant depending on how the octopus in the hopper enters, many of them are not sucked.

Further, the octopus may be stuck to the suction nozzle, and even if the suction is released, the octopus may not fall by its own weight. If the octopus is dusty, the nozzle holes of the suction nozzles will be clogged with the moisture that has been transferred and the powdery dust will be present.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a variant adsorption transfer device capable of reliably adsorbing and transporting a variant in a hopper.

[0007]

SUMMARY OF THE INVENTION A variant adsorption and transfer device according to the present invention comprises a hopper having holes on the bottom surface and capable of accommodating a large number of irregular products in a random arrangement, and an upper tray for receiving the irregular products. While having a through hole in the longitudinal direction that passes through the center of the tray part, enters into the hopper from each hole on the bottom surface of the hopper, scoops up a variant in the hopper, and ascends to a predetermined transfer position, and A rake rod that can be lowered to a retracted position below the bottom surface, a moving means for moving the rake rod up and down, and a rake rod inserted into the through hole of the rake rod,
A claw rod that is movable relative to the scooping bar so as to rise to a push-up position for pushing up the odd-shaped object of the saucer portion, and to descend to a retracted position where the saucer portion can receive the odd-shaped object; Has a moving means for relatively moving the scooping bar at a predetermined timing, and a suction nozzle capable of confronting the respective pans at the upper end of the scooping bar at a predetermined interval, and switching the three-way valve to vacuum and atmospheric pressure. A suction position for adsorbing the odd-shaped object pushed up by the push rod in opposition to each tray part of each scooping rod that has been raised to the transfer position above the hopper. And a suction box that is movable between a discharge position that releases suction of the odd-shaped object by releasing suction at a predetermined discharge position that is disengaged from above the hopper. Characterized in that a moving means for moving the adsorption box.

Further, in addition to the above-mentioned structure, the variant adsorption and transfer device according to the present invention surely ejects the variant that has been adsorbed and transferred at the ejection position, and as a means for preventing clogging of the adsorption nozzle, at the time of ejection. A drop rod that penetrates the suction nozzle from the inside of the suction box to drop the odd-shaped object, and a moving unit that moves the drop rod to a retracted position above the suction nozzle and a drop position that penetrates the suction nozzle are provided. Good.

Further, in order to prevent powder and the like from accumulating in the saucer portion at the upper end of the scooping bar to make it difficult to scoop irregularly shaped objects,
It is preferable that the center has a truncated cone shape and a plurality of side surfaces are vertically elongated.

[0010] Further, the abutting rod can surely carry the irregular shaped material toward the suction nozzle, and the area where the irregular shape itself contacts and sticks to the irregular shape is small, so that the irregular shape is easily adsorbed by the adsorption nozzle. Therefore, it is preferable that the tip has a truncated cone shape.

In addition, when filling a baking die for octopus baking with octopus, a plurality of holes on the bottom of the hopper, a plurality of rake rods and a plurality of thrust rods are provided, and a plurality of suction nozzles are provided correspondingly. Well, in that case,
In order to obtain a large adsorption force, the adsorption box is divided into two chambers, and in addition to the three-way valve, a two-way valve is arranged in the vacuum passage to one chamber and the introduction passage of atmospheric pressure. It is preferable that the atmospheric pressure can be introduced into the two chambers with a time lag.

Further, if the scooping bar scoops the irregular shape only at the same place on the bottom of the hopper, the probability of scooping is reduced and stirring is less likely to occur, so that the probability of scooping the irregular shape in the hopper is increased. While making the hole on the bottom of the hopper a long hole in one of the horizontal direction,
It is preferable to provide a moving means for horizontally moving the hopper in the long axis direction of the elongated hole within a range where the elongated hole does not deviate from the elevating position of the scoop rod. The long holes are preferably set so that the long axis direction is oblique to the arrangement direction of the rake bars so that the area occupied by the holes can be maximized.

Further, in order to increase the probability of scooping the irregular shape in the hopper, it is preferable to raise the scooping bar at least twice, and for this purpose, for example, the adsorption box adsorbs the irregular shape to the adsorption nozzle. The rake bar down to the retracted position below the bottom of the hopper, then move the hopper to another position, then move it to its original position, and move it to another position again. At the same time, the rake bar is once raised to an intermediate position between the first movement and the second movement, and then returned to the retracted position, and then the suction box is returned to the suction position according to the timing. Means for controlling each moving means may be provided to raise the rake.

Further, in order to prevent the irregularly-shaped substances remaining without being adsorbed from sticking to the saucer portion and hindering the next scooping, it is preferable to eliminate the irregularly-shaped substances not adsorbed from the saucer portion. After the suction box adsorbs a foreign substance on the suction nozzle at the suction position on the hopper, temporarily lowers the protruding rod to the retracted position, and then moves the scoop bar before the suction box starts moving. A means for controlling each moving means is provided so as to descend to the intermediate position, stop temporarily, and then raise the thrusting rod again at that position to forcibly remove the odd-shaped object remaining in the pan portion of the scooping rod. Good.

[0015]

In the apparatus of the present invention, irregularly shaped products, such as octopus roasted octopus, are randomly stored in the hopper.
Then, it is scooped by the scooping bar and adsorbed by the suction nozzle of the suction box that has moved to the delivery position above the hopper. At this time, the deformed object is pushed up by the thrusting rod toward the suction nozzle to facilitate suction. Then, the deformed product is transferred to the ejection position on the baking mold or the like by the adsorption box while being adsorbed, and the adsorption is released at that position to drop.

Further, when the drop bar is provided, the drop bar penetrates the suction nozzle from the inside of the suction box at the time of discharging, thereby forcibly discharging the odd-shaped object.

Further, when the saucer portion at the upper end of the rake rod has a shape of a truncated cone in the center and a plurality of side surfaces are opened vertically, powder or the like is discharged from the saucer portion when the variant is, for example, an octopus grilled octopus. The saucer is always kept in a state suitable for scooping odd-shaped objects.

Further, when the tip of the thrusting rod has a truncated cone shape, the irregular shape is supported by the upper surface of the truncated cone and pushed up toward the suction nozzle without falling. Moreover, since only the upper surface of the truncated cone comes into contact with the irregular shape, the adhesive force does not become excessive, and therefore the irregular shape is easily adsorbed by the adsorption nozzle.

Further, when a plurality of holes on the bottom surface of the hopper, a scooping rod and a thrusting rod are respectively provided and a plurality of the suction nozzles are provided correspondingly, the suction box is divided into two chambers,
A two-way valve in addition to the three-way valve is installed in the passage for introducing vacuum and atmospheric pressure into one chamber, and the vacuum and atmospheric pressure are introduced into the two chambers with a time lag, so that the vacuum is initially concentrated in one chamber. Then, the suction force of each suction nozzle increases, and a vacuum is introduced into the other chamber while the odd-shaped object is suctioned to these suction nozzles, and the remaining suction nozzles start suction, so that the suction force doubles.

Further, in the case where the hole on the bottom of the hopper is elongated in one direction in the horizontal direction and the hopper is horizontally moved in the longitudinal direction within the range in which the elongated hole does not deviate from the ascending / descending position of the rake bar, By moving the, the scoop bar scoops the profile at different positions on the bottom of the hopper and also stirs the profile in the hopper. As a result, the probability of scooping odd-shaped objects in the hopper increases.

When the holes on the bottom of the hopper are elongated holes, the major axis of the elongated holes is increased and the movement distance of the hopper is increased by setting the major axis direction to be oblique with respect to the arrangement direction of the rake rods. You can increase the probability that the scooping stick will scoop up odd-shaped objects.

Further, the suction box sucks the odd-shaped object by the suction nozzle and moves toward the ejection position, and after the rake bar descends to the retracted position below the bottom of the hopper, the hopper is moved to another position. While moving to the original position and then to another position again, the rake bar is once raised to the intermediate position between the first movement and the second movement, then returned to the retracted position, and then the suction box By providing a means to control each moving means so that the scooping bar is lifted at the timing when the scooping bar returns to the suction position, the scooping bar can be lifted twice, and the odd-shaped object in the hopper is scooped up. Becomes higher.

In addition, after the suction box has sucked the odd-shaped object to the suction nozzle at the suction position on the hopper, the thrust bar is once lowered to the retracted position, and then the scoop bar is moved to the intermediate position before the suction box starts moving. It is not adsorbed by providing a means for controlling each moving means so as to forcibly remove the odd-shaped object left in the saucer part of the rake rod by lowering it to a temporary stop and raising the thrusting rod again at that position. It is possible to prevent the irregular shaped object from sticking to the saucer portion and hindering the new scooping.

4 and also controls the three-way valve 11 and each two-way valve 12, 1.
It is operated by controlling No. 3, and its operation is roughly as follows.

Adsorption box 5 in which the adsorption nozzle 7 adsorbs octopus
When the baking mold 2 on the octopus baking machine conveyor 3 comes to the loading position below the suction box 5 in a state where it has advanced to the loading position indicated by the two-dot chain line on the left side of FIG. 1, a photoelectric sensor (not shown) Detects it. Then, the system is started by the detection signal, the three-way valve 11 (S4 in FIG. 2) is switched to the atmosphere side, and the atmospheric pressure is introduced into the adsorption box 5 (vacuum break),
Next, the octopus dropping cylinder 15 (S6 in FIG. 2) is turned off.
When N is operated, the drop rod 14 penetrates the suction nozzle 7, and the octopus is dropped to fill the baking die (see FIG. 3).

Next, the rodless cylinder 6 (S in FIG. 2)
1) starts moving backward toward the hopper side, and the suction box 5 moves backward. Then, the cylinder 20 for raising and lowering the rake rod (see FIG.
S2) starts moving from the lower limit toward the intermediate position, and the scooping bar 18 scoops up the octopus and rises to the intermediate position (see FIG. 3).

When the suction box 5 reaches above the hopper 1,
The cylinder 20 (S2) for raising and lowering the rake rod moves from the intermediate position to the upper limit position, and the rake rod 18 rises to the transfer position with the octopus placed. And the three-way valve 11
(S4) is switched to the vacuum side, and the suction nozzle 7 of the chamber 8A on one side of the suction box 5 starts sucking the octopus on the upper surface of the rake rod 18 (see FIG. 3).

The cylinder 22 for moving the thrust rod
(S7 in FIG. 2) is turned ON, the stick 23 pushes up the octopus toward the suction nozzle 7 so that the octopus can be easily adsorbed, and the two-way valve 12 (S5 in FIG. 2) of the branch pipe 10B is opened. The vacuum is also introduced into the other chamber 8B of the suction box 5, and the remaining suction nozzle 7 sucks the octopus (see FIG. 3).

After passing the octopus to the suction nozzle 7, the cylinder 22 (S7) for moving the stick is turned off,
The thrust rod 23 descends to the upper end surface of the rake rod 18. Then, the cylinder 20 (S2) for raising and lowering the rake rod moves toward the intermediate position, and the rake rod 18 descends to the intermediate position and temporarily stops. At this time, the cylinder 22 for moving the thrust rod
(S7) is turned on again, and the thrust rod 23 is lifted. The octopus that is not adsorbed and remains on the scoop 18 is pushed off by this. Moreover, after the rake rod 18 descends to the intermediate position, the rodless cylinder 6 (S1) starts forward movement (see FIG. 4).

The rodless cylinder 6 (S1) is moved forward, and the suction box 5 moves toward the loading position on the conveyor 3 side while the suction nozzle 7 sucks the octopus. On the other hand, the cylinder 20 for raising and lowering the rake rod (S2) moves to the lower limit side, and the cylinder 21 for moving the thrust rod is turned off, so that the rake rod 18 and the thrust rod 23 do not interfere with the hopper 1 below the bottom surface. It descends to the retracted position (see FIG. 4).

Next, the cylinder 24 for moving the hopper
(S3 in FIG. 2) operates three times to the forward side, then to the reverse side, and to the forward side, whereby the hopper 1 first moves to the first position on the forward side, and then to the reverse side. It moves to the second position and again to the first position on the forward side. As a result, the position of the hopper 1 is changed every cycle, the scooping bar 18 does not scoop at the same place, and the octopus is prevented from being biased into a bridge shape in the hopper 1 and the probability of scooping the octopus is reduced. Becomes higher. Then, between the first movement and the second movement, the rake rod elevating cylinder 20 (S2) is activated, the rake rod 18 once rises to the intermediate position, and then returns to the retracted position. By this motion, the motion of scooping the octopus is effectively performed twice, and the probability of scooping increases. (See Figure 4).

This completes one cycle. And
Returning to the above, the same operation is repeated. In the case of continuous operation, the cycle is, for example, 10 seconds (in the case of the example of FIG. 2). Of course, this cycle can be changed appropriately.

A two-way valve 13 (S8 in FIG. 2) provided in a passage for opening the vacuum cleaner 9 side of the vacuum introduction pipe 10 to the atmosphere is a three-way valve 11 (S
When 4) is switched to the atmosphere side, the vacuum cleaner 9 is temporarily opened so that the vacuum cleaner 9 does not run in the closed state and become overheated, whereby the atmosphere is introduced and the inside of the vacuum cleaner 9 is cooled.
