Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-stage switching boxing device in a tilting type automatic weighing machine for fruits for automatically weighing and packing fruits, such as tangerines, which have relatively soft skins and are easily damaged by selection impact. It is about.

[0002]

2. Description of the Related Art In general, as an apparatus for packing and weighing (weighing) fruits at a fruit sorting place for tangerines or the like, a predetermined empty box (cardboard box) with a flap opened in the past is provided with an opening directed upward. It is placed on a weighing platform of a weighing machine in an upright posture, and tangerines or the like are dropped or filled from fruit supply means, such as a belt conveyor or the like, disposed above an empty box on the weighing platform directly or through an appropriate discharging means to perform predetermined weighing. Was
42-21703, Japanese Utility Model Publication No. 56-10644, etc.). In this case, the falling distance from the falling point of the fruit, which is the end of the fruit supply conveyor, to the bottom of the empty box with the upper opening located below is at least the depth of the upright empty box body and the width of the open flap added. The length and the drop were set to be large, and the impact when the fruit reached the bottom of the cardboard box was large, and it could not be said that it was an optimal weighing device for a fruit with a soft peel such as a tangerine. For this reason, recently, in order to alleviate the drop impact as much as possible, the posture of the empty box placed on the weighing machine is previously set to the inclined state, so that the feeding conveyor can be arranged close to the weighing machine side. The drop between the end of the feeding conveyor and the bottom of the empty box can be set smaller than that of the box body in the upright posture.Fruits flow from the tip side of the inclined flap, and after a predetermined weighing is completed, the fruit is inclined. To return to a normal posture (standing position). (For example, Japanese Patent Application Publication No. Hei 6-69 presented earlier in this application.)
No. 806).

[0003] In addition, the shape and size of cardboard boxes for packing oranges (fruits) and the like have so far been mainly large boxes for packing 15 kg. Due to the tendency and the smaller number of people, the medium type of 10kg packed box has become mainstream. In particular, recently, small box-type products packed in 5 kg have been favored as gifts.

[0004]

However, a single empty box (for example, for packing 10 kg) is used as an empty box transfer line for weighing using a tilting type automatic weighing machine currently installed at a fruit sorting place. This is the configuration of one chain-type transfer line that only transfers empty boxes. For this reason, when empty boxes of other sizes (for example, empty boxes for packing 5 kg) are flown and packed and weighed, if the existing transport line is to be used immediately, all empty boxes on the transport line are temporarily removed. It must be replaced with a new empty box, and the replacement work is troublesome. Moreover,
At this time, if the set position of the fruit feeding means with respect to the box weighing supply path is not changed along with the change in the size of the box, the desired drop to the inclined empty box cannot be obtained, and the apparatus itself must be appropriately corrected. It also needs to be applied.

Of course, it is difficult to separately arrange a dedicated transfer line for empty boxes of other sizes and a weighing device associated therewith, due to the laying area and the like, and this leads to an increase in the size of the device.

For this reason, the emergence of a combined-type box packing device capable of transporting and weighing at least two types of boxes, large and small, has been awaited.

In view of the above-mentioned circumstances, the present invention has a three-dimensional arrangement of two transport lines for flowing two types of empty boxes of a large and small type with respect to a single weighing machine mechanism, and the two empty lines are provided in a supply path to the weighing machine side. A fruit providing means for efficiently switching and tilting a box, and a fruit supply means itself for dropping fruits to an inclined empty box can also be changed vertically and horizontally so that the fruit drop point can be changed, and the fruit to solve the above problem It is an object of the present invention to provide a two-stage switching boxing device in a tilting type automatic weighing machine.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a tilting type automatic weighing machine for fruits and the like, in which an empty box facing a predetermined weighing table is inclined and weighed with the minimum impact of filling and falling, two types of empty weighing machines are used. Two conveyor-type empty box transport lines for transporting boxes are arranged in upper and lower two stages, and a single box weighing supply path for horizontally loading one empty box on one side of this lower empty box transport line is orthogonal. The box weighing supply path is formed at the base end with a movable receiving plate for tilting an empty box at a fixed angle and a fixed inclined receiving plate to form a V-shaped pedestal opening 90 °, and a position above the V-shaped pedestal. Is provided with a temporary receiving inclined dropping plate for temporarily receiving and tilting and dropping an empty box to be fed horizontally from the upper empty box transfer line, and a box extruded body of a moving arm which moves in the longitudinal direction in a groove valley of a V-shaped receiving stand. The switching type inclined empty box feeding means is arranged in the middle of the fixed V-shaped cradle connected to the V-shaped cradle. The stand-by means is provided with inclined weighing means for mounting a weighing V-shaped pedestal connected to the fixed V-shaped pedestal at the tip on a weighing stand of a weighing machine, and weighing is performed at the end portion of the inclined weighing means. A fixed-quantity box return unit with a discharge roller is provided which is always a movable V-shaped pedestal connected to the V-shaped pedestal, and a flap portion of the inclined empty box at the back-up standby means and the inclined weighing means. Above, a fruit supply means composed of a back-in conveyor section, a large-size conveyor section and a parallel small-size conveyor section which are orthogonally connected to the fruit main supply conveyor, and the upper and lower parts are arranged in response to a weighing box switching signal. The lower empty box is horizontally placed on the movable receiving plate of the inclined empty box feeding means, or the upper empty box is placed on the movable receiving plate and the fixed inclined receiving plate. Is mounted on the V-shaped pedestal by tilting and falling.

In this case, the fruit supply means of the back-filling conveyor section, the large-size conveyor section, and the small-size conveyor section are provided by a syringe.
It is mounted on a movable base that can move up, down , left and right, and the drop point of each conveyor section is changed according to the size of the inclined empty box.

As described above, in the two-stage switching boxing device of the tilting type automatic weighing machine, the empty box transport line for transporting two kinds of empty boxes having different sizes is constituted by two upper and lower stages, and the lower empty box transport line is provided. The box weighing supply path is made orthogonal to the side of the box, and the empty box is loaded in the horizontal standby movable receiving plate of the switching type inclined empty box feeding means at the base end by laterally extending the movable receiving plate. The empty box is set in an inclined posture as a V-shaped pedestal with the opposed fixed inclined receiving plate.

On the other hand, when another empty box (small empty box) for transferring the upper empty box transfer line is used, the movable receiving plate of the switching type inclined empty box feeding means is inclined by a predetermined switching signal to fix the inclined box. A V-shaped pedestal is previously formed with the receiving plate, and the upper empty box horizontally fed is temporarily received by the temporary receiving inclined dropping plate, and the temporary receiving inclined dropping plate is tilted to one side so that the empty box can be dropped in an inclined manner. Then, the V-shaped pedestal facing directly below is set in a tilted manner to directly receive an empty box while being tilted.

For this reason, the upper or lower inclined empty boxes (large and small empty boxes) to be appropriately switched to and placed on the V-shaped cradle position.
The subsequent steps are the same for both, when the movable arm at the groove position of the V-shaped pedestal is pushed out to the front back-fill standby position by being pushed, and is placed on the weighing platform of the weighing machine at the back-fill standby position. In order to alleviate the impact of the above, a small amount of fruit (orange) is previously dropped from the main supply conveyor side through the backfilling conveyor section and allowed to flow.

Thereafter, a slightly filled inclined empty box is loaded on the weighing V-shaped table of the weighing machine due to the pressing of the rear inclined empty box, and the large empty conveyor flowing from the main supply conveyor side enters the inclined empty box. The main drop filling is performed through the section, but when the fruit reaches the pre-set value close to the quantitative value, the large-size conveyor section is switched to the small-size conveyor section, and one drop is dispensed to obtain the quantitative value. The inclined box body filled with the fruit in a predetermined amount moves to the next-stage fixed box body returning means, and is turned back to a horizontal state to head to the discharge conveyor path.

In switching the box from the large empty box to the small empty box or from the small empty box to the large empty box, the falling point of the fruit on the inclined empty box is changed at the same time. That is, it is moved (up or down, left or right) to a moving base on which a back-filling conveyor section for directly feeding fruits, a large-size conveyor section, and a small-size conveyor section are mounted. And is filled near the flap portion with a minimum head.

An open V-shaped receiving tray 8 is formed, and a temporary receiving part for receiving an empty box A 'which is horizontally fed by a pusher 9 from the upper empty box transporting line 2 at a position above the V-shaped receiving tray 8. An inclined drop plate 10 is provided, and a box extruding body 13 of a moving arm 12 that moves in the longitudinal direction by a stroke of an empty box width with a rodless cylinder 11 with little distortion is arranged in a groove valley 8 a of the V-shaped pedestal 8. The switching type inclined empty box feeding means 14 is connected to the fixed V-shaped pedestal 8 at the middle part thereof, and the back-up standby means 16 of the fixed V-shaped pedestal 15 is connected to the fixed V-shaped pedestal 15 at the tip end. A weighing V-shaped receiving table 17 is provided on a weighing table 18a of a weighing machine 18 with inclined weighing means 19. Numeral 20 denotes a movable V-shaped pedestal having a discharge roller 22 attached to one surface thereof connected to the weighing V-shaped pedestal 17 of the inclined weighing means 19, and the movable V-shaped pedestal 20 always maintains a V-shaped posture, After receiving the box A ″, the cylinder 21 returns to the fixed-quantity box returning means 23 for returning to the horizontal position.

Further, the flap portion Aa of the inclined empty box A (A ') coming to the back-fill standby means 16 and the inclined weighing means 19
Above (Aa '), a back-filling conveyor section 25 orthogonal to the lower end of the telescopic belt conveyor type fruit main supply conveyor 24 projecting separately from the machine body and parallel to the box weighing supply path 4.
And large dispensing conveyor section 26 and parallel dispensing conveyor section 2
7 is provided. Reference numeral 29 denotes a moving base on which the back-in conveyor 25, the large-size conveyor 26, and the small-size conveyor 27 are mounted.
Consists of a lifting platform 31 which is raised and lowered by a vertical cylinder 30, and a sliding platform 35 which is provided with a wheel 33 for rolling a rail 32 laid on the upper surface of the lifting platform 31 and which slides left and right by a horizontal cylinder 34. Each drop point a of the conveyor unit 25, the large-size conveyor unit 26, and the small-size conveyor unit 27 is variable. 36
Is a vertical rack provided on the leg 31a of the elevating platform 31,
A pinion 38 disposed on the side of the pedestal 37 engages with the pinion 38 to provide a support mechanism that compensates for the uniform elevation of the cylinder 30. FIG.
The vertical cylinder 30 shown in FIGS. 4 and 15 has a configuration in which two cylinders are vertically connected, so that three stages of ascending and descending movements are possible based on the total amount of expansion and contraction of each rod.

The operation will now be described. First, a large empty box A and a small empty box A 'are successively transferred to an empty box transfer line 1 and an empty box transfer line 2 which are parallel in two stages.

Here, for example, when a predetermined amount of tangerine B is packed in a large empty box A of the lower empty box transfer line 1, when the box A reaches a predetermined position of the empty box transfer line 1, a sensor is appropriately provided. (Not shown), the empty box transport line 1
Lever 47 provided at the lower portion of the box A is raised by the operation of the cylinder 48, and the stop rod portion 47a protrudes above the transport surface, so that the empty box A
Is stopped, and in this state, the pusher 3 is arranged at right angles to the side.
The push plate 3b at the rod end of the cylinder 3a protrudes laterally, and the push plate 3b presses the side surface of the empty box A to switch to the base end of the box weighing supply path 4 orthogonal to the transport line. The box receiving means 14 is mounted on the movable receiving plate 6 which is always horizontal. When the empty box A is placed on the movable receiving plate 6, the lower cylinder 5 operates to extend the rod, and the movable receiving plate 6 is pivotally connected to the base end 6a.
The V-shaped pedestal 8 is opened at 90 ° with the fixed inclined receiving plate 7 inclined at a fixed angle (45 °) with the fulcrum as a fulcrum, and the empty box A is set to the inclined posture.

As described above, when the empty box A is inclined at an angle of 45 °, the box extruded body 1 at the end of the groove 8a of the V-shaped support 8 is pushed out.
Since the movable arm 12 moves in the groove 8b in the longitudinal direction at least by the width of the box by the operation of the cylinder 11, the inclined empty box A becomes the fixed V-shaped receiving unit 16 serving as the back-up standby means 16 at the next stage. The process moves to the platform 15. At the position of the fixed V-shaped cradle 15, the mandarin orange B fed from the fruit main supply conveyor 24 is dropped by an appropriate amount in advance from the end of the backing conveyor part 25 arranged on the side, and the inclined empty box A is weighed. Only when shifting to the gantry 15, the drop impact of the cans B is reduced. Of course, the inclined empty box A is maintained in the inclined position by the fixed V-shaped pedestal 15, and the drop point a of the back-filling conveyor section 25 is located close to the top of the flap portion Aa, and the drop to the bottom of the inclined empty box A is located. Is set to the minimum, so that drop filling with less impact is performed.

Thereafter, when a predetermined amount of the weighed inclined empty box A located on the weighing V-shaped pedestal 15 of the preceding weighing machine 18 is clogged, the fixed V-shaped pedestal 15 is caused by the weighing signal. The inclined empty box A subjected to the back-filling action is fed to the weighing V-shaped pedestal 15 on the weighing machine 18 side in conjunction with the pushing of the inclined empty box A on the subsequent V-shaped pedestal 8 side.

The inclined empty box A reaching the weighing V-shaped receiving table 15
, A larger amount of tangerine B is dropped and filled from the large-size conveyor section 26 orthogonal to the fruit main supply conveyor 24 arranged on the side. In this case, it is difficult to obtain a quantitative value at once with a fruit having a weight of about 100 g per mandarin such as a tangerine, and it is difficult to reach a predetermined quantitative value.
(9.5 kg value when packed in kg) Switch to dropping for one piece. Of course, the inclined empty box A in the weighing V-shaped receiving table 15 keeps the inclined posture, the drop point a of the large-size conveyor section 26 is located close to the upper portion of the flap portion Aa, and the back-filling drop is caused. Then, the bottom position rises and becomes the minimum head, so that the main drop with less impact is filled.

Here, an inclined empty box A on the weighing V-shaped pedestal 15
When the weighing device 18 reaches a preliminary value close to the quantitative value, the fruit main supply conveyor 24 that supplies oranges B to the large dispensing conveyor portion 26 by the switching signal of the weighing machine 18 slides back and forth by the cylinder 39. A known telescopic mechanism 2 having a belt conveyor 24a that is S-shaped via a head pulley 39b provided on the 39a and a movable tension pulley 39c.
4b, the length of the conveyor is reduced, and the falling point a is retracted to the backing conveyor section 25 on the front side, so that the supply of the tangerine B from the fruit main supply conveyor 24 is switched to the backing conveyor section 25 and the large-out conveyor section. The drop of 26 stops.

At this time, the small-sized conveyor 40 for dispensing, which is a single-row feed and is arranged side by side on the main fruit supply conveyor 24, sends the rotating mandarin orange B to the dispensing conveyor section 27 as one piece, so that the small dispensing conveyor section 27 is used. When the droplets are dropped from the falling point a and reaches the fixed value, the rotation of the dispensing conveyor section 27 is stopped immediately, so that the inclined empty box A is prevented from being over-packed. The illustrated small dispensing conveyor section 27 is integrated with the large dispensing conveyor section 26. However, since the supply of oranges to the large dispensing conveyor section 26 is cut off when the fruit main supply conveyor 24 is retracted, it is difficult to drop one. Do not come.

Next, the inclined quantitative box A ″ in which the oranges B are filled with the quantitative value is placed on the weighing V-shaped pedestal 17 of the subsequent inclined empty box A.
And is transferred to the movable V-shaped cradle 20. When the fixed amount box A "is placed on the movable V-shaped pedestal 20, the cylinder 21 provided at the lower portion is operated to contract the rod.
Is rotated while guiding the position regulating rail 42 with the fulcrum as the fulcrum, thereby returning the surface of the discharge roller 22 to the horizontal plane, thereby returning the inclination of the fixed amount container A ″ to the normal position. The fixed amount box A ″ is a holding rod 49 attached to the discharge roller surface side.
Presses the side surface with the spring 44, so that even if there is a difference in the size of the box, horizontal rotation without swinging is performed. After that, the discharge roller 22 is forcibly discharged by rotation of the motor 43 and is sent out to the front discharge path 45.

When a small empty box A '(5 kg packed box) is packed in place of the large empty box A (10 kg packed box), the predetermined position of the upper empty box transport line 2 is changed by an appropriate switching signal. The pusher 9 arranged on the side works to push out the empty box A 'conveyed through the empty box transport line 2 by the push plate portion 9b at the end of the cylinder 9a to the side, and the horizontal temporary receiving inclined falling plate 10 is always horizontal.
Put on. At this time, the lower switching type inclined empty box feeding means 1
The movable receiving plate 4 is rotated to form a V-shaped receiving stand 8 together with the fixed inclined receiving plate 7.

Here, the temporary receiving inclined falling plate 10 is
When the rod 6 is contracted by operating the rod 6 to incline in a one-way manner with the pivot point 10a as a fulcrum, the empty box A 'on the temporary receiving inclined dropping plate 10 is inclined and slides down, and the empty box A' is inclined. As it is, it fits directly into the V-groove of the V-shaped cradle 8 directly below to form an inclined empty box A '(see FIG. 12). After the inclined empty box A ′ is fitted to the V-shaped pedestal 8 and becomes inclined, the movement of the inclined empty box A ′ is performed similarly to the movement of the large empty box A, and the box extruded body 13 of the groove 8a of the V-shaped pedestal 8 is moved. The tilting empty box A 'is moved to the fixed V-shaped pedestal 15 of the next-stage back-up standby means 16 by the operation of the cylinder 11.

In this case, the size of the small empty box A 'is smaller than that of the large empty box A in height, width and the like.
When the small empty box A 'is placed on the fixed V-shaped pedestal 15 and the weighing V-shaped pedestal 17 in an inclined manner, the flap portion Aa', the backing conveyor portion 25 facing upward, the large-size conveyor portion 26, and the small-size dispenser. If the drop point a of the conveyor section 27 is not changed, the head will increase. At this time, the movable base 29 is slid left and right and moved up and down.

That is, in the mode of the small empty box A ', since the drop point a is too high, the vertical cylinder 30 for raising and lowering the moving base 29 is actuated in advance to lower the raising and lowering base 31 slightly.
By operating the horizontal cylinder 34, the elevator 31 is slightly slid with the wheel 33 toward the box (see FIG. 15).

Here, the inclined empty box A 'placed on the V-shaped pedestal 8 moves the moving arm 12 of the box pushing body 13 of the groove 8a in the longitudinal direction by the operation of the cylinder 11 in the same manner as described above. It is fed into the fixed V-shaped pedestal 15 serving as the back-up standby means 16 for the step. Similarly to the fixed empty V-shaped pedestal 15, the mandarin orange B is appropriately dropped from the back-filling conveyor 25 in the same manner as described above, and then transferred to the weighing V-shaped pedestal 17. From 26, the main supply of oranges B is dropped. At this time, since each drop point a of the back-filling conveyor portion 25 and the large-size conveyor portion 26 moves forward and descends and approaches the flap portion Aa 'of the inclined empty box A', the oranges B are dropped and filled with a minimum drop. You.

After the mandarin orange B packed in the inclined empty box A 'at the weighing V-shaped pedestal 17 reaches the pre-set value, the dispensing conveyor section 2
Drop one from 7 and fill to a fixed value. Tilt quantitative box A ″ in which mandarin orange B is packed to a quantitative value by weighing V-shaped receiving table 17
Is moved to the movable V-shaped pedestal 20 by pushing the subsequent inclined empty box A to the weighing V-shaped pedestal 15, and the movable V-shaped pedestal 20 is also rotated in the same manner as described above so that the fixed amount box A ″ is horizontally moved. It returns to the position and sends it out to the discharge path 44.

[0032]

As described above, the two-stage switching box packing device in the tilting type automatic weighing machine for fruits and the like according to the present invention comprises two conveyor-type empty box transfer lines for two types of large and small empty boxes. At the base end of the box weighing supply path orthogonal to one side of the lower empty box transport line, the V is formed by a movable receiving plate and a fixed inclined receiving plate that incline the lower empty box at a fixed angle. The V-shaped pedestal is used as an inclined empty box, and the V-shaped pedestal is used to receive an empty box to be fed from the upper empty box transfer line by being inclined and dropped via a temporary receiving inclined dropping plate. The configuration in which the two empty boxes are inclined at the same location leads to a compact device, can be installed even on a small site, and can be switched efficiently with empty boxes. .

In addition, the two types of empty boxes inclined by the V-shaped pedestal are pushed out to the fixed V-shaped pedestal serving as back-up standby means of a single box weighing supply path with a movable arm, and the fixed V-shaped pedestal is pushed out. At the cradle position, a small amount is filled in advance with a back-filling conveyor section that is orthogonal to the side and the impact is reduced when the weighing platform is shifted to the V-shaped cradle, and the weighing time on the weighing platform is reduced. The large dispensing conveyor unit, the back-conveying conveyor unit and the small dispensing conveyor unit for the inclined empty box at the time of the transfer are configured to be mounted on a movable base that can be vertically moved and slidable left and right by a cylinder. Depending on the size of the sloping empty box facing the gantry (change in box size), the drop point at the end of each conveyor section and the drop to the bottom of the sloping empty box can be easily adjusted each time. Drop filling of fruits with little impact is possible. In particular, this is suitable for weighing and boxing of perishable fruits such as oranges, which are soft and easily damaged.

Further, a movable pusher for feeding out empty boxes in the upper and lower two-stage empty box transfer line, rotation of the movable receiving plate, feeding of the moving arm, and returning means for returning the fixed quantity container connected to the weighing V-shaped receiving table. The structure of the V-shaped cradle, in which the rotation of the V-shaped cradle and the operation of the movable base for moving the back-up, large-out, and small-out conveyors are operated by a driving mechanism using a cylinder mechanism, causes failure, breakage, and malfunction during long-term use.
