Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a tray pack removal device that removes tray packs used in box packing of agricultural products such as persimmons and melons one by one from a stacked state.

[0002]

2. Description of the Related Art Tray packs used for packing agricultural products in boxes are of a type in which recesses for receiving agricultural products one by one are formed. Or it is usually made of paper and has the property of being relatively easily deformed,
Agricultural products to be packaged are usually sorted according to their rank, so different sizes are packed in a common size box. There is a feature that the arrangement pattern such as the shape or the staggered shape is often different. As a result of using a plurality of types of tray packs in which recesses for storing agricultural products differ according to the number and arrangement pattern of boxed balls, when tray packs are supplied to the boxing device, the tray pack unloading means of the same configuration is shared as it is. However, it is not easy to generalize the apparatus, and this poses a problem that does not exist in an apparatus for taking out a single standard tray pack.

[0003] As a conventional tray pack removing device, a device utilizing suction means is generally known. For example, there is a system in which trays are stacked above a clamping mechanism for clamping both end edges of the tray, and the lowest tray is taken out one by one over the adsorber clamping mechanism by a suction-type separating device (Japanese Patent Laid-Open No. HEI 9-163572). 8-26484).

[0004] However, this suction type tray take-out device is not suitable for taking out a tray pack used for packaging agricultural products as described above. That is, as described above, tray packs used for packaging agricultural products usually handle items having different numbers of wrapped balls and arrangement patterns, but in such a case, the positions of the recesses are not constant, and the recesses are not fixed. Cannot be adsorbed, and appropriate adsorption cannot be performed unless the adsorption position is changed. Further, in the method of taking out the tray pack over the above-mentioned holding mechanism, the above problem is further increased because the stability of suction is further required to take out the tray pack by overcoming the holding resistance.

[0005] Further, there has been proposed a method in which the lowermost tray pack is sucked downward by a suction method, and the second tray pack from the lowermost stage is pressed by a chuck claw (Japanese Patent Laid-Open No. 5-3388).
No. 05), but also in this case, it is not suitable for taking out a tray pack for agricultural product packaging in which the concave portion for accommodating the agricultural product to be packaged changes variously according to the number of balls and the arrangement pattern in the same manner as described above. .

Further, as an apparatus for taking out the uppermost one of the stacked tray packs one by one upward, a claw which is engaged with an edge of the uppermost tray pack is rotated, and the next claw which rotates together with the claw is rotated. Has been proposed (see Japanese Patent Application Laid-Open No. 8-1), which functions to engage so as to press the upper surface of the edge of the second tray pack and to forcibly separate the uppermost tray pack.
No. 27430). However, this apparatus is suitable for a tray pack which is relatively strong and does not deform, but is not suitable for a relatively thin tray pack made of synthetic resin.

[0007]

Next, the operation of the tray pack take-out device 9 having the above configuration will be described.

First, in a state where the empty boxes 5 are waiting on the tray pack insertion stage 506 shown in FIG. 13, when agricultural products of a predetermined sorting section are sent to the box standby conveyor 404, a predetermined signal is not shown. The controller 6 (hereinafter the same) applies the tray pack laminated body 6 having the recesses of the number of balls or the arrangement pattern to be used for packing the agricultural products of this sorting category to the tray pack receiving stand 6021 or 6
022 to the tray pack removal stage 601 and stop. In this state, the lift mechanism 604 is driven, and the transferred tray pack stacked body 6 placed on the lift table 605 is lifted by the lift mechanism 604 (see FIG. 1).

The sensor 912 detects that the rise of the tray pack stack 6 has reached the tip height positions of the claws 9101 and 9102 in which the top and bottom edges of the second tray pack 6 are vertically aligned. Then, the drive of the lift mechanism 604 is stopped by the control device. As a result, the claw device 910 faces the upper and lower outer edges between the upper and lower edges of the second tray pack 6 (see FIGS. 2 and 7).

Next, the air cylinder device 913 for horizontal driving is driven by the control device, and the pair of claw devices 9 opposed to each other are driven.
10 is moved inward, and the claws 9101, 9 of the claw device 910 are moved.
The drive of the air cylinder device 913 is stopped at the time when 102 is advanced and inserted between the upper edge and the upper and lower edges of the second tray pack 6 (see FIG. 3).

Subsequently, the controller separates the uppermost tray separation claw 9102 from the vertical driving air cylinder device 9.
It is moved up by the drive of No. 15. At this time, since the second tray pressing claw 9101 is fixed to the bracket 914, the stationary state is continued. Therefore, one of the claws 9 moving upward
101 lifts the uppermost tray pack 6 upward, while the second tray pack 6 is pressed upward by the other claw 9102, so that both tray packs are separated vertically, and the uppermost tray pack 6 is lifted. Only 6 is surely suspended by the lifting section 901 (see FIGS. 4 and 8).

In this state, the lift mechanism 604 is driven to slightly lower the lift table 605, thereby separating the second tray pressing claw 9101 from the lower tray pack laminate 6, and then using the slide cylinder device 802. The support head 904 is moved above the empty box 5 waiting on the tray pack insertion stage 506 (see FIG. 5), and then the cylinder device 903 is driven to lower the support head 904, as indicated by the arrow in FIG. As described above, the picked-up tray pack 6 is inserted into the empty box 5.

As described above, the stacked tray packs 6
The operation of taking out the uppermost ones one by one and fitting them into the empty box 5 is completed, and the driving means such as the cylinder devices perform the operation of returning to the initial position to be ready to take out the next tray pack. You.

According to the tray pack unloading device 9 of the present embodiment having the above-described configuration, the soft tray packs 6 made of a relatively thin synthetic resin or the like used for packaging agricultural products are stacked, and the uppermost stage thereof is removed. Can be reliably separated from the second one and taken out one by one.

Further, the tray pack 6 taken out can be moved above the empty box 5 and fitted by simply moving the tray pack 6 substantially horizontally in the suspended state.
A series of operations such as insertion into an empty box can be performed quickly, and a mechanism used for the operation can be configured relatively simply.

Moreover, the tray pack take-out device 9 of the present embodiment.
Is not a suction method, so it always operates in exactly the same way even for a plurality of tray packs that have recesses for accommodating agricultural products one by one and differ in the number (ball number) and arrangement pattern. Since there is no need to change the specification design and application when taking out many types of tray packs, there is an advantage that the versatility is extremely high.

Further, there is obtained an advantage that it is possible to cope with a case where there is an inclined tray pack described below with reference to FIGS.

That is, as shown in FIG. 11, even when some of the tray packs are in a tilted state in the tray pack stack, the tray pack take-out device 9 of this example is also used.
Is based on detection information from a sensor 912 provided in association with the pair of claw devices 910,
And a horizontal driving air cylinder device 9 fixed to the support head 904 and moving the bracket 914
By controlling the driving of the pair 13 so that each pair operates independently, there is an advantage that the tray pack 6 in such an inclined state can be reliably separated and taken out.

In other words, when the uppermost tray pack 6 is inclinedly stacked on the tray pack laminated body as shown in FIG. 11, the tray having the independently operated horizontal driving air cylinder device 913 is provided. Pack removal device 9
First, the sensor 912 _R on the right side of FIG. 11 (hereinafter, the right member of FIG.

In this state, since the sensor 912 _{L on} the left side of FIG. 11 (hereinafter, the left member of FIG. 11 is denoted by the letter “L”) does not reach between the uppermost step and the edge flange of the second tray pack, The device 910 _L maintains that state. The lift mechanism 60
4 is to continue the ascent operation continuously, or to resume the ascent after the right claw device 910 _R is temporarily stopped until it is inserted between the top and bottom edge flanges of the second tray pack. Provided.

[0056] The left sensor 91 that has reached between the left gripper device 910 _L of Figure 11 the edge flange of the top and second tray pack by increasing the lift mechanism 604
When 2 _L is detected, the lifting mechanism stops lifting,
The driving of the left horizontal driving air cylinder device 913 _L, left-side gripper device 910 _L is inserted between the uppermost stage and the edge flange of the second tray pack (see FIG. 12).

Thereafter, the uppermost tray pack 6 is separated from the second tray pack 6, suspended and inserted into the empty box 5 in the same manner as the operation from FIG.

As described above, according to the apparatus of the present embodiment, even when there are tray packs that are stacked at an angle in the laminate, it is possible to take out one sheet at a time. The effect is achieved.

[0059]

As described above, according to the present invention,
The effect of being able to take out one sheet at a time from the state in which soft tray packs made of relatively thin synthetic resin used for packaging agricultural products are stacked and separated from the second one with certainty. Is played.

Further, the tray pack taken out can be moved above the empty box and fitted by simply moving the tray pack substantially horizontally in the suspended state. The above operation can be performed quickly and the mechanism used for the operation can be configured relatively simply.

Further, since the tray pack take-out device of the present invention does not use the suction system, recesses for accommodating agricultural products one by one are formed, and the number (ball number) and arrangement pattern are different. The same operation can be performed for a plurality of tray packs to ensure reliable removal, so that it can be used as it is for removing many types of tray packs without the need to change the specification design or application. This makes it possible to provide an apparatus having extremely high versatility.

Further, according to the invention of claim 4 of the present application, even when some of the tray packs are in an inclined state in the tray pack laminated body, the claw devices are operated independently of each other. In addition, it is possible to reliably insert the claw device corresponding to a position having a different height due to the inclination, and it is possible to always surely separate and take out the tray pack even in the inclined state.

The tray pack take-out device of the present invention having various effects as described above is extremely effective especially as a device for stably and reliably taking out a tray pack provided with a recess for accommodating agricultural products one by one. is there.
