JPH0664607A - Partition with movable flap for boxing long product such as carrot - Google Patents

Abstract

PURPOSE:To provide a partition for vertically sectioning inside a box when boxing long products such as carrots by an automatic boxing machine, wherein drop impact force of the carrots or the like is buffered, standing fluctuation due to a backlash is prevented for securing boxing in a neatly arranged state with gaps reduced and also damage of the carrots or the like is avoided. CONSTITUTION:On a plurality of partitioning longitudinal plates 1 vertically positioned with a predetermined interval along a lateral direction, a required number of movable flaps 2 are pivoted to the sides so that the flaps can be vertically rotated. The movable flap 2 is maintained horizontal by force applied by an elastic material 11. When a carrot or the like is dropped into a box 3 while they remain lateral onto an upper face of the movable flap 2, the movable flap 2 rotates downward against the force applied by the elastic material 11, thereby buffering drop impact. As soon as the carrot or the like drops on the bottom of the box 3, the movable flap 2 rotates upward to recover horizontal, thereby preventing undesired standing fluctuation due to a backlash of the carrot or the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an automatic boxing machine for carrying long objects such as carrots, radish and other long fruits and vegetables and fish into the boxes one by one for horizontal alignment and packing. The present invention relates to a partition plate suitable for partitioning the box body into a plurality of compartments and sequentially arranging carrots and the like in the compartments.

[0002]

2. Description of the Related Art Conventionally, when shipping carrots, radish, long eggplant, etc., they are once collected at a collection point, and after a predetermined pretreatment process such as washing and sorting, they are quantitatively packed in a predetermined box body such as a corrugated box. I am trying to do it.

[0003] In this case, when a long object having a taper such as carrots is packed in a box, it must be packed in the box body while being aligned in a predetermined direction. This means that the body cannot be packed by a predetermined amount.

Therefore, it is desirable that the long product as described above be packed in a box manually, but this requires a lot of manpower and is extremely inefficient.

Therefore, an automatic cartoning machine that can efficiently pack long items such as carrots is currently in use. This type of machine is first shown in FIG. The object a is conveyed in the laid-down sideways state by the supply conveyor b which is a belt with a crosspiece and is conveyed to one. Then, the long object a is dropped from the front end portion of the supply conveyor b, and a plurality of compartments e, e are laterally sectioned in a predetermined direction by a partition plate d provided in advance on the box c. to _1, e _2, e _3, continue to fill successively sideways, after the end of the quantitative filling of the respective compartment E～e _3, by extracting the partition plate d from the box c, aligned box c It is packed so that it will be in a state.

[0006]

However, in the conventional partition plate d as described above, since the inside of the box c is merely divided laterally into a required plurality, it is put into the box c. The long object a hits the bottom surface c ′ of the box c or the filled long object a ′ in the box c and jumps up, becomes slanted, or stands upright as shown in the figure. Therefore, there is a case where the accommodation in the box c is deteriorated, and it becomes impossible to carry out the quantitative alignment packing in the lateral direction.

This is particularly noticeable in taper-shaped long objects such as carrots because it is difficult to maintain a horizontal horizontal state at the time of drop-movement due to imbalance of weight in the length direction. Become.

In view of the above-mentioned problems of the prior art, the present invention drops into the box body by attaching an appropriate flap to a partition plate when the long object is boxed by using an automatic boxing machine. It reduces the impact of falling long objects and suppresses jumping up, and also prevents standing after falling to improve the fit inside the box and ensure a reliable quantitative alignment packing. Moreover, the purpose is to avoid damage to carrots as much as possible.

[0009]

In order to achieve the above object, the present invention allows a long object such as carrot to be sequentially divided and carried into a box body in a laid sideways state by being dropped from a supply conveyor. As such, a partition plate used to divide the box body into a plurality of vertically divided compartments by inserting the box body in a predetermined direction. Each of the partition vertical plates is provided with a support frame at the upper end, and the movable flap has a lateral width set to be narrower than each of the compartments of the box and the partition vertical length. On the side surface of the plate, the long object dropped and carried in from the supply conveyor is pivotally attached so that it can be hit and rotated and lowered by the hit, and the movable flap has its rotation. Long objects by descending The rotational force of the elastic material is urged so that the lower impact can be alleviated and that the long object can be immediately rotated to the original position in the horizontal state after passing through the falling motion. An object of the present invention is to provide a partition plate with a movable flap for packaging a long product such as carrots characterized by the above.

[0010]

By vertically inserting a plurality of vertical partition plates into the box body, the box body is vertically divided into adjacent compartments in a predetermined direction. The movable flap pivotally attached to each partition vertical plate is held in a state orthogonal to the partition vertical plate by the biasing force of the elastic material, so that it is in a horizontally projected state in each compartment.

An automatic cartoning machine prepared separately has a supply conveyor for transferring long products such as carrots to a sorting machine, and the supply conveyor is in a state of laying down one long product. That is, it is equipped with a belt with a crosspiece to be conveyed in a horizontal direction, and the above-mentioned long object is dropped from one end thereof to one by one and sequentially carried into each compartment of the box.

In the above case, the box body is made to correspond to the drop point of the supply conveyor so that the long object falls on the upper surface of the movable flap in the required compartment to be filled. Is dropped on the upper surface of the movable flap in the compartment, and the impact caused by the fall causes the movable flap to be rotated and lowered against the biasing force of the elastic material, which alleviates the impact of dropping the long object.
It falls to the bottom of the box.

When the long object falls from the relatively low movable flap, the movable flap is rotatably raised by the urging force of the elastic material and returns to the original position in the horizontal state.
As a result, the long object that hits the bottom surface of the box and jumps up is suppressed by the back surface of the movable flap, and unintentional rolling such as standing up is prevented.

The above is the case where only one movable flap is projected in the compartment at the end of the box, but it is defined by two front and rear vertically long partitions for partitioning. If two movable flaps are provided on opposite sides of the vertically elongated partition plates and staggered at predetermined intervals in the vertical direction, the long objects that fall are Since the movable flap, the lower movable flap, and the bottom of the box are dropped in this order, the impact force of the long object can be mitigated in two steps, and the bounce can be further reduced and damage to carrots, etc. It can be avoided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings. As shown in FIGS. 1A and 1B, a plurality of (three in the illustrated example) vertical partition plates 1, 1 for partitioning are provided. ... and a plurality of movable flaps 2, 6 in total (6 in the example shown).
It is composed of and.

The vertical plates 1 for partitioning are box bodies 3.
A pair of left and right members that can be inserted into and removed from (a cardboard box or the like) and are formed to have a height dimension corresponding to the depth of the box body 3 and can be placed on the upper opening edge of the box body 3. Support frame 4,
By fixing both left and right ends of the upper part to 4, a predetermined interval l in the front-back direction (left-right direction in FIG. 1A) is obtained.
Are installed vertically.

Each of the vertical partitions 1, 1, ... Can be formed of an aluminum plate, a synthetic resin plate or the like. By holding the pair of support frames 4, 4 by an electromagnet or the like (not shown). The vertical plates 1 for partitioning can be inserted into or removed from the box 3 by being supported by an appropriate lifting mechanism.

Therefore, in the box body 3, the vertically long partition plates 1 and 1 for partitioning are provided.
As shown in FIG. 1 (A), the inside of the box 3 is divided into four compartments 5 by inserting the ...
It will be divided into 6, 7, and 8.

In the illustrated example, the movable flaps 2 are pivotably provided on the front side surface 1a and the rear side surface 1b of each of the partition vertical plates 1 ... That is, when the carrot illustrated as the elongated object 9 falls and hits the movable flaps 2, the impact force becomes as small as possible and the carrot is not easily scratched. Alternatively, an aluminum plate whose surface is coated with a synthetic resin sheet, a rubber sheet, urethane rubber, or the like is used.

As shown in FIG. 1 (A), a total of two pieces are provided at appropriate intervals in the vertical direction at the upper part of the front side surface 1a and the lower part of the rear side surface 1b of each of the vertically elongated partition plates 1. The movable flaps 2 and 2 are pivotally attached by hinges 10 so as to rotate downward from a horizontal position shown in the drawing to a substantially vertical state. In other words, the upper and lower movable flaps 2 and 2 that project into the compartments 6 and 7 in the adjacent vertically elongated partition plates 1 and 1 have the lower movable flap 2 when the upper movable flap 2 rotates downward. The carrots are pivoted at appropriate intervals in the up-down direction so that the carrots drop from the upper movable flap 2 onto the lower movable flap 2 without contacting the movable flaps.

As shown in FIGS. 2 and 3, the hinge 10 in the illustrated example has a coil spring 1 as an elastic member 11 on a pivot 10c to which bases of two substrates 10a and 10b are pivotally attached.
1a is wound around each end 11b of the coil spring 11a,
1c is hooked on the backsides of the substrates 10a and 10b, respectively, and both substrates 10a and 10b are held by the elastic force of the coil spring 11a.
b is held at the orthogonal position shown by the solid line in FIG. 2, and from this perpendicular position, against the elastic force of the coil spring 11a,
The substrate 10b is formed so as to be rotatable up to a substantially vertical position indicated by a chain double-dashed line in FIG.

When the hinge 10 as described above is used, as shown in FIG.
As shown in FIG. 3, one of the substrates 10a is fixed to the side surface of the vertical partition plate 1 with screws 12, ... And the pivotally attached portion of the hinge 10 is installed in a window hole 13 formed in the vertical partition plate 1. By fixing the base portion of the movable flap 2 to the upper surface of the other substrate 10b in a superposed state and fixing it with screws and nuts 14 ..., The movable flap 2 is pivoted so as to be perpendicular to the vertically elongated partition plate 1.

In order to hold the movable flap 2 laterally at a position orthogonal to the longitudinal partition plate 1, the elastic member 11 for urging the movable flap 2 is not the coil spring 11a but the elastic member 11. It is also possible to use urethane rubber 11d as shown in FIG.

In this case, the urethane rubber 11d is the substrate 1 to which the movable flap 2 of the hinge 10 is fixed, as shown in the figure.
It can be interposed between the back surface of 0b and the side surface of the vertically elongated partition plate 1. Therefore, due to the impact force of the fall of the carrot on the movable flap 2, the urethane rubber 11d
Is compressed and deformed so that the movable flap 2 rotates and descends as shown by the chain double-dashed line in the figure, and the restoring force of the movable flap 2 causes the movable flap 2 to rotate and rise to the horizontal position and be held at that position. Becomes

Here, in FIG. 1 (A), reference numeral 15 is a supply conveyor in the automatic packing apparatus, which is provided with a belt with a crosspiece for carrying one carrot in a horizontal direction, which is not shown. A sorting machine is installed in the front stage.

Therefore, in order to use the partition plate with movable flaps, as shown in FIG. 1 (A), first, as shown in FIG. 1 (A), by inserting the vertically long partition plates 1, 1, ... In this state, the supply conveyor 1 is divided into a plurality of parts.
5, the desired compartment 5 of the box 3 placed at the lower end of the
Corresponds to the fall position of carrot.

From the above state, by rotating the supply conveyor 15 in the direction of the arrow B shown in the drawing, the carrots are conveyed laterally to one of them, dropped from the tip of the supply conveyor 15 into the compartment 5, and horizontally. It falls on the movable flap 2 in the state.

Since the movable flap 2 is rotated and lowered against the biasing force of the elastic member 11 due to the impact force caused by the fall of the carrot, the impact on the carrot is relieved,
It does not jump from the top of the movable flap 2 and falls to the bottom of the box body 3 while still falling down.

At this time, the carrot is dropped on the bottom of the box 3 or on the carrot a already stored in the box 3, but the impact caused by the drop is alleviated by the movable flap 2 as described above, and Since it falls from the movable flap 2 which is a low place, the impact is small and the jumping at this time is small. Further, since the movable flap 2 immediately rotates and rises due to the urging force of the elastic material 11 and returns to the original horizontal position at the same time when the carrot drops to the bottom of the box body 3 or the like, even if the carrot jumps up, it is still movable. The back surface of the flap 2 prevents its rising, so that the flap 2 is prevented from standing up, and therefore the long object 9 such as carrot is not damaged.

In the above description, ginseng is mentioned,
In addition, it is of course possible to adopt long-sized fruits and vegetables such as radish, long eggplant, and cucumber, fish, and the like even in the case where they are aligned and packed when they are dropped into a box from a certain height.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, the box body is vertically divided into a plurality of parts in a predetermined direction, and a long object such as carrot is placed sideways in each compartment. When dropping and carrying in as it is and sequentially dividing and filling, the movable flap rotates and descends against the urging force of the elastic material due to the fall of carrot, etc., so that the impact at the time of falling on carrot etc. is alleviated. It is possible to prevent the carrot from jumping up due to the impact at the time of the fall, and it is possible to further reduce the impact when the movable flap falls to the bottom of the box. Bounce when it hits the bottom surface or carrot etc. already inside the box becomes very small, and even if it jumps a lot, it will rotate up due to the biasing force of the elastic material. The movable flap, which is held in a horizontal position, prevents its rise from occurring, so there will be no more gaps between carrots than necessary and it will fit better, and it will be possible to pack it in a box that looks good on the outside. Damages such as carrots can be avoided.

Further, when the vertically long partition plate is pulled out from the box, the movable flap is rotated and lowered by the carrot etc. filled in the upper part of the box, so the carrots already divided and filled. It does not disturb the alignment packing etc.
