Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vibration device for aligning and packing long bodies such as carrots, radishes, and lengths packed in boxes (corrugated boxes, etc.) by applying vibration to the boxes.

[0002]

[Prior art]

 In order to pack a long body such as carrots, it is necessary to arrange the long objects inside the box and arrange them so that they are in the specified direction, or between the long bodies and between this and the side wall of the box. As a result, undesired gaps are created, and it becomes impossible to fill the inside of the box until the specified amount is reached.

Therefore, it is general that the long body as described above is packed in a box manually, but this requires a lot of manual labor and is inefficient. An automatic cartoning machine has been already proposed for efficient cartoning.

According to this automatic cartoning machine, a long conveyor is conveyed in a recumbent state in a direction orthogonal to the conveying direction by a supply conveyor using a crosspiece belt that conveys one long piece. From the end of the supply conveyor, they are successively dropped into the box and packed sideways.

However, when the automatic boxing machine as described above is used, when the long object falls into the box body, the long object hits the bottom surface of the box body or other long objects and jumps up. As a result, Since the elongated body changes its posture such as becoming slanted or standing up, the fit inside the box becomes worse, and more than necessary gaps are created. In some cases, it will not be possible to perform alignment and packing.

Therefore, there is also proposed a box packing device in which a partition plate inserted into the box body is rocked together with the box body so that long objects supplied from the upper part are filled in an aligned state ( (See Japanese Patent Laid-Open No. 58-183412).

[0007]

[Problems to be solved by the device]

 However, this type of device merely applies a vertical vibration to the box body by a vibrator, or applies a horizontal swing in a predetermined direction to the partition plate and the box body. However, since the gap between the elongated bodies is only slightly reduced, the filling effect that can be satisfied cannot be enhanced.

In view of the problems of the above-mentioned conventional technique, the present invention not only moves the box body back and forth by reciprocating the box mounting table in the front-back direction, but at this time, By making the body sway like a seesaw around the fulcrum that provides the bottom of the body, a gap is created by the movement of a long object such as vegetables in the longitudinal direction and the movement based on the weight of the long object. Its purpose is to be able to carry out alignment packing without any.

Further, in claim 2, by placing a weight on the long object stored in the box body, it is possible to suppress the unintentional dance of the long object being exposed, and The purpose is to obtain a uniform aligned packing without the unevenness of the long part of the protruding part.

[0010]

[Means for Solving the Problems]

 To achieve the above object, the present invention provides, in claim 1, a box mounting table having a bottom wall, a front wall, and a rear wall, and a reciprocating drive mechanism for horizontally reciprocating the box mounting table in a predetermined direction. The box mounting table has an inner width in the reciprocating direction set to allow the box mounted on the bottom wall to move freely, and the box mounting table has the same reciprocating motion as above. By this, the fulcrum portion is projected upward from the bottom wall so that both upper side portions of the box body can swing in a seesaw shape until they hit the front wall and the rear wall of the box body mounting table. We are trying to provide a vibrating device for aligning and packing long objects such as carrots inside the box.

Further, according to a second aspect of the present invention, there is provided a box mounting table having a bottom wall, a front wall and a rear wall, and a reciprocating driving mechanism for horizontally reciprocating the box mounting table in a predetermined direction. The inner width in the reciprocating direction is set to a size that allows the box placed on the bottom wall to move freely, and both sides of the box can be moved by the reciprocating movement of the box placing table. A fulcrum is projected upward from the bottom wall so that the upper part can swing in a seesaw shape until it hits the front wall and the rear wall of the box mounting table, and a long object in the box body. An attempt is made to provide a vibrating device for aligning and packing long objects such as carrots in a box, which is provided with a weight formed so as to be freely placed on the exposed upper surface.

[0012]

[Action]

 Long items such as vegetables are packed by an automatic cartoning machine in a predetermined direction so that they are aligned. The box body is placed on the box body mounting table such that the longitudinal direction of the long object matches the reciprocating direction of the box body mounting table.

Next, when the reciprocating drive mechanism is operated to reciprocate the box mounting table in the front-back direction, the box not only reciprocates back and forth together with the box mounting table, but also a fulcrum on the bottom wall. The box body swings like a seesaw around the part, and as a result, the upper end side of the box body alternately pivots largely in the front-rear direction, and vibration is applied to the box body.

With the swinging of the box body in both the front and rear directions, the front side portion and the rear side portion of the top portion of the box body hit the front wall and the rear wall of the box body mounting table, respectively. As a result, an impact force is applied to the box and the long object, and this impact force is directed in the longitudinal direction of the long object. The long objects slide in the longitudinal direction, and due to the slip and the weight of the long object from above, the long object spreads symmetrically in the longitudinal direction, which is the longitudinal direction. As they mesh with each other, they can fit inside the box without any gaps.

Further, according to a second aspect of the present invention, the weight placed on the front surface of the long object prevents the long object on the front surface from jumping up, and at the same time, the long object is boxed. Since it is pressed into the body, the long objects can be packed in a more desirable state without any gaps.

[0016]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, it comprises a box mounting table 1 and a reciprocating drive mechanism 2 that reciprocates the box mounting table 1 in the front-rear direction (left-right direction in the drawing).

The box mounting table 1 shown in the figure has a bottom wall 1a, a front wall 1b, and a rear wall 1c, so that the upper surface and the left and right side surfaces are openings 3, 4, and 4, respectively. It is formed in an upward U-shape, and the front and rear parts of the box body 5 can be placed inside the front and rear walls 1b and 1c with a predetermined gap a, b therebetween. The inner width L in the direction is set larger than the lateral width 1 of the box body 5 by a required dimension.

Further, in the present invention, a fulcrum portion 6 on which the center of the bottom surface of the box 5 is placed is formed in the center of the bottom wall 1a of the box mounting table 1 on its inner surface. , A triangular shape or the like is provided so as to project long in parallel with the front wall 1b and the rear wall 1c, whereby the box body 5 has a seesaw shape as shown by arrows c and c'in FIG. It is slidable in the front-back direction.

The box mounting base 1 configured in this manner facilitates horizontal reciprocal movement in the front-rear direction on the flat plate-shaped substrate 7 via the guide means 8 such as rails and rollers. It has been placed.

The reciprocating drive mechanism 2 includes a rotary plate 10 fixed to a rotary shaft 9a of a motor 9, a crank shaft 11 protruding from the rotary plate 10, and a protrusion protruding from a rear wall 1c of the box mounting table 1. The racket 12 and a link 13 that connects the racket 12 to each other.

Further, in the box body 5, in claim 2, the weight 15 is placed on the exposed upper surface of the carrot and other long objects 14 packed in the box body 5. There is.

The weight 15 is formed into a plate having a predetermined thickness so that its weight is evenly applied to the exposed surface of the elongated object 14 in the box body 5, and the weight 15 is biaxially oriented. The size is set so that it is just fitted into the box body 5, and a handle 16 is provided on the upper surface thereof.

Therefore, when using the above-mentioned vibrating device for aligning and packing, if the box body 5 in which the long objects 14 are packed is placed on the bottom surface 1 a of the box body mounting table 1, the reciprocating drive mechanism 2 By moving the box mounting table 1, the box mounting table 1 is reciprocated in the front-rear direction.

Here, the long objects 14 are packed by the above-mentioned automatic packaging device or the like so that the longitudinal direction thereof is oriented in the front-rear direction with respect to the box body 5. In the case of packing by dropping into 5, the considerable gap d remains between the long objects 14 and between the box body 5 and the long objects 14 as shown in FIG. However, the alignment is not uniform and the filling is not satisfactory.

The box body 5 thus packed with the long objects 14 is placed on the box body mounting table 1 as shown in FIGS. 1 and 2, and the reciprocating drive mechanism 2 operates to move the box body 5 to the arrow e in FIG. , E ′ is horizontally reciprocated in the front-rear direction, the box 5 is reciprocated together in the front-rear direction. At this time, the upper side of the box 5 around the fulcrum 6 is indicated by an arrow e in FIG. , E ′, it is swung greatly like a seesaw.

As described above, when the upper side of the box body 5 is repeatedly rotated in a large arc shape, the upper front side portion and the upper rear side portion of the box body 5 are connected to the front wall 1 b and the rear side of the box body mounting table 1. The front edge 1d and the rear edge 1e of the wall 1c collide with each other, and vibration due to the impact force is applied to the long object 14 in the front-rear direction (longitudinal direction) via the box body 5.

Therefore, the long objects 14 slide in the longitudinal direction thereof, and the load due to the weight of the long objects 14 causes the long objects 14 to move in the front-back direction (left-right direction in the drawings) as shown in FIGS. To be aligned without any gap along the inner surfaces of the front wall 5a and the rear wall 5b of the box body 5.

Further, in the present invention, the weight 15 placed on the surface of the long object 14 presses the long object 14 downward. Since the weight 15 is also applied as a load to the long object 14 without the 14 jumping unintentionally, desired alignment packing is completed within a short time.

[0029]

[Effect of device]

 Since the present invention is configured as described above, according to the first aspect, an impact force is applied by the box mounting table by swinging the box body in a seesaw shape instead of merely reciprocating laterally. Therefore, long vegetables that have been packed in a box are subjected to sufficient vibration in the longitudinal direction of the vegetables, causing the long objects to slide and to be symmetrically spread in the longitudinal direction. The existing gaps will be filled up and the desired alignment box filling state can be efficiently completed.

Further, according to claim 2, the long object is pushed into the box body by the weight, and the vibration is efficiently applied in the longitudinal direction. In addition to being able to perform efficiently, it is possible to prevent the long object from jumping up on the upper surface of the exposed surface, so that the elongated object on the upper surface of the exposed surface does not deviate.
