Description

TECHNICAL FIELD The present invention relates to a device for changing the posture of an article, and more particularly to a device for changing the posture of an article, such as a triangular rice ball, which tends to tip over when conveyed in an upright posture.

On the production line for mass-produced triangular rice balls at the factory, a rice ball forming machine, a packaging machine, and a label inspection machine are arranged from upstream to downstream. It is conveyed to the label inspection machine in the posture. In the label inspection machine, the product label attached to one side of the triangular rice ball along the conveying direction and the bar code label attached to the other side of the triangle are inspected simultaneously from both sides.

The triangular rice balls that have passed through this inspection process are transported to the downstream metal detector, but just before that, they are knocked over by the posture changing device. This is because the height of the ceiling when passing through the metal detector is low, and if the object is transported in an unstable upright position, it is not possible to tell which side will face upward when the object falls over.

Therefore, the attitude changing device provided between the label inspection machine and the metal detector must turn over the object to be conveyed in a fixed direction within a short distance. The reason why it is turned over in a certain direction is that it is necessary to check the product label attached to the side in the boxing area provided downstream of the metal detector.

As a device that meets such a demand, for example, a device that stops a triangular rice ball at a predetermined position and then pushes it from the side by a pusher is known (see Patent Document 1).

JP-A-9-142427

However, the device described in Patent Document 1 stops the triangular rice ball at a predetermined position and then pushes it from the side with a pusher to turn it over. Therefore, with this device, the triangular rice ball must be stopped at a predetermined position each time, which poses a problem that the processing capacity of the production line cannot be increased.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a posture changing device capable of overturning an object, such as a triangular rice ball, which tends to tip over when transported in an upright position, at a predetermined position in a certain direction while transporting the object. and

In order to solve the above problems, a posture changing device according to the present invention includes:
A posture changing device for overturning a transported object transported in an upright posture while transporting,
a first guide member in contact with one side surface along the conveying direction of the conveyed object;

The first guide member is in contact with the transported object at a position higher than the second guide member, and extends diagonally downstream so as to intersect the transport path of the transported object,
The first guide member and the second guide member are separated in a range that does not intersect vertically,
The first guide member is characterized in that it extends longer downstream than the second guide member while maintaining a height for laying down the transported object.

As a result, the object to be conveyed is sandwiched between the first guide member in contact with one side surface and the second guide member in contact with the other side surface, and is given a rotational force centered on the conveying direction. gradually tilts as it is transported, and eventually topples over. At this time, since the first guide member maintains the height at which the conveyed object falls down and extends longer downstream than the second guide member, the conveyed object falling toward the second guide member It is conveyed without riding on the guide member.

A posture changing device according to claim 2 is the posture changing device according to claim 1, wherein the first guide member is in contact with the transported object at a position higher than the center of gravity of the conveyed object, and the second guide member is positioned higher than the center of gravity of the conveyed object. It is characterized by contact at a low position.

As a result, the object to be conveyed is pushed in opposite directions at a position higher than the center of gravity and a position lower than the center of gravity, and a rotational force is applied to the object to be conveyed. Therefore, the transport direction length of the posture changing device can be shortened.

A posture changing device according to claim 3 is the posture changing device according to claim 1 or 2, characterized in that the first guide member and the second guide part are arranged substantially in a figure of eight when viewed from above. Characterized by

As a result, the rotating object sandwiched between the first guide member and the second guide member can be overturned in the middle of the conveying path, and can be conveyed downstream as it is.

A posture changing device according to claim 4 is the posture changing device according to any one of claims 1 to 3, wherein at least one of the first guide member and the second guide member has an angle intersecting with the conveying direction. It is characterized by being variable.

As a result, the crossing angle of the first guide member and/or the second guide member with the conveying direction can be adjusted. , the object to be conveyed can be overturned substantially in the middle of the conveying path.

A posture changing device according to claim 5 is the posture changing device according to any one of claims 1 to 4, characterized in that the positions of the first guide member and the second guide member are variable.

As a result, even if the center of gravity of the object to be conveyed is displaced vertically depending on the type, the object to be conveyed can be reliably overturned substantially in the middle of the conveying path simply by changing the position of each guide member. Here, changing the position is a concept including changing the distance between the first guide member and the second guide member and changing the height position of each. In addition, the variable position includes the case where one of the first guide member and the second guide member is fixed and the mounting position of the other is adjustable, or the case where both mounting positions are adjustable. .

The inspection system according to claim 6 of the present invention,

a metal inspection machine arranged downstream of the attitude changing device in the conveying direction;
with
The first guide member and the second guide member are characterized by being made of non-metal.

As a result, even if the posture changing device is brought close to the metal inspection machine, malfunction of the metal inspection machine is suppressed. Even if the first guide member and the second guide member that are in contact with the object to be conveyed vibrate or the like, because they are made of non-metal, the disturbance may cause the metal inspection machine to erroneously detect (metallic foreign matter). because there is no

The inspection system according to claim 7 of the present invention,

As a result, the object to be conveyed, which is in an unstable standing posture, can be reliably laid down (overturned) in advance before being sent to the weight inspection machine, thereby improving the weight inspection accuracy. can be done.

According to the posture changing device of the present invention, it is possible to transport an object, such as a triangular rice ball, which tends to tip over when transported in a standing position, while transporting the object over a short distance with one side facing upward. Therefore, the production capacity can be improved as compared with the conventional device that stops the conveyed object.
In addition, according to the inspection system of the present invention, since the posture changing device for changing the unstable posture to the stable posture is arranged in the front stage of the device that must be inspected in a stable posture, the inspection device in the latter stage can Inspection accuracy can be improved.

FIG. 4 is a schematic plan view of an attitude control device according to a modification of one embodiment of the present invention;

A posture changing device as an embodiment of the present invention and an inspection system 100 including the same will be described below with reference to the drawings. In addition, the embodiment shown below does not limit the technical scope of the present invention. Also, here, a triangular rice ball is shown as the transported object M, but the transported object M is not limited to this. For example, the transported object M may be a square or round rice ball. Further, for example, the transported portion M may be a stand pouch (pouch pack).

FIG. 1 shows an external perspective view of an inspection device that inspects a label attached to a transported object M while transporting the transported object M, and FIG. It is the side view which looked at the upstream from the downstream. In these figures, the inspection apparatus 1 comprises an operation box 3 having an operation display section 2 on the top thereof, a transport section 4 for transporting an object to be transported M in an upright position in the direction of arrow F, and the transport section 4. A label inspection machine 5 positioned upstream to inspect the print quality of labels attached to the objects M to be conveyed, and a label inspection machine 5 positioned downstream of the label inspection machine 5 to distribute objects M with poor print quality. It is provided with a sorting section 6, a posture changing device 7 positioned downstream of the sorting section 6 to overturn the transported object M in a standing posture, and a support leg 8 for supporting them.

Further, a belt conveyor 401, a belt conveyor 402, and a belt conveyor 403 for conveying the articles to be packaged M sent from the conveying section 4 are connected to the downstream side of the posture changing device 7 (see FIG. 6). A metal inspection machine 102 and a weight inspection machine 103 are arranged along these belt conveyors 401-403. The metal inspection machine 102 is a device that inspects whether or not a metallic foreign matter is contained in the transported object M passing through the inside. Further, the weight inspection machine 103 is an inspection machine capable of measuring the weight (mass) of a passing object M without stopping transportation, and inspects the weight of the object M for insufficient weight, excess weight, mismatch, and the like. In this embodiment, the inspection system 100 includes these inspection machines and the inspection apparatus 1 of FIG. , detailed description is omitted.

As shown in FIG. 2, the conveying section 4 is composed of a belt conveyor 40. Above the conveying path, guide rods 41 and 42 for holding an object to be conveyed M in an upright state are provided on both sides of the conveying path. is provided in Therefore, the transport path described here is the belt conveyor 40 . As can be seen from FIG. 2, the conveying unit 4, the label inspection machine 5, and the posture changing device 7 are arranged so that the conveyed object M is horizontally conveyed while leaning against the guide rod 41 on one side. 8 is obliquely attached. The guide rods 41 and 42 are arranged so that the distance between the guide rods 41 and 42 is about the width of the transported object M (slightly larger than the width of the transported object M) so that the transported object M can be transported in an upright state. are placed.

One guide rod 41 extends as far as the attitude changer 7, as shown in FIG. and the downstream side is discontinued). This is because the conveyed material M with poor print quality is removed from the belt conveyor 40 by the distribution unit 6 on the downstream side. Therefore, the belt conveyor 40 is attached so that the guide rod 41 side is inclined in the horizontal plane so that the object to be conveyed M can be maintained in an upright position. As a result, the transported object M leans against the guide rod 41 and can be kept upright. Further, the guide rod 42 on the near side in FIG. 1 is supported by the strut 43, and the guide rod 41 on the opposite side is supported by the strut 80 which will be described later. Moreover, these columns 43 and 80 are attached so as to be vertically movable, so that the height of each guide rod 41 and 42 from the belt conveyor 40 can be changed.

The label inspection machine 5 inspects the printing quality of the label L attached to the object to be inspected M, and is configured to inspect the label for printing errors, missing characters, label attachment errors, etc. by imaging the label with a camera. ing. Also, different labels are attached to both sides of the transported object M along the transport direction F. As shown in FIG. For example, one side is attached with a product label printed with the product name and price, and the other side is attached with a bar code label printed with raw materials, additives, and barcodes. Therefore, in this embodiment, the label inspection machines 5 are arranged on both sides of the belt conveyor 40 . The label inspection device 5 performs inspection by, for example, comparing image data of the imaged label and image data of the correct label. For example, OCR (Optical Character Recognition) analyzes the characters contained in the image, matches the character information between the imaged label and the correct label (so-called OCV (Optical Character Verification) inspection), and image data The suitability of the type of label affixed to the object to be conveyed M and the suitability of the content printed on the label are inspected based on the matching of the characteristic portions between them (inspection by so-called pattern matching).

An air nozzle (not shown) is arranged along the guide rod 41 in the distribution unit 6, and when the upstream label inspection machine 5 determines that the printing is defective, the air nozzle intersects the transport direction with respect to the determined transported object M. , an air jet is ejected in the opposite direction of the guide rod 41 to remove it from the belt conveyor 40. - 特許庁Therefore, a discharge space without a guide rod 42 is provided on the side of the belt conveyor 40 between the label inspection machine 5 and the posture changing device 7, and a defective product collection box (not shown) is attached there. ing.

As shown in FIG. 5, the posture changing device 7 includes a first guide member 71 in contact with one side surface of the transported object M along the transport direction F, and a second guide member 71 in contact with the other side surface of the transported object M opposite to the one side surface. 2 guide members 72 are provided. The first guide member 71 is arranged to contact the object M at a position higher than the second guide member 72 and extend obliquely downstream in the conveying direction so as to intersect the conveying path of the object M to be conveyed. ing.

Also, the first guide member 71 and the second guide member 72 are separated from each other within a range that does not intersect vertically. Here, "do not intersect vertically" means that the first guide member 71 and the second guide member 72 are viewed from the direction normal to the conveying surface (the upper surface where the conveyor 40 is in contact with the object to be conveyed M) (hereinafter referred to as substantially planar view). does not intersect vertically.

Further, the first guide member 71 maintains the height at which the transported object M is tilted and extends longer downstream than the second guide member 72 . In this case, the second guide member 72 may be arranged in parallel with the belt conveyor 40, but in order to make the conveyed object M kneaded and overturned in the middle of the conveyor 40, as shown in FIG. It is preferable to arrange the first guide member 71 and the second guide member 72 in a substantially eight-shape in plan view. In other words, the first guide member 71 and the second guide member 72 are arranged so as to gradually approach each other toward the downstream side when viewed from above.

As a result, the object to be conveyed M sandwiched between the first guide member 71 and the second guide member 72 and conveyed receives a rotational force about the conveying direction F from the guide members 71 and 72. , the transported object M to be transported overturns substantially in the middle of the belt conveyor 40 . In addition, this allows the first guide member 71 and the second guide member 72 to reliably come into contact with both side surfaces of the object M to be transferred. Further, the first guide member 71 and the second guide member 72 have portions closer than the width of the transported object M so that the rotational force can be reliably applied to the transported object M. ing. That is, since the first guide member 71 and the second guide member 72 having different heights are closer to each other than the width of the object to be transferred M, the object to be transferred M is placed in a vertical position between the first guide member 71 and the second guide member 72 while standing. It cannot pass between the guide members 72 . Therefore, the posture control device 7 causes the transported object M to overturn with certainty.

In order to perform the above operations more efficiently, the first guide member 71 is arranged so as to be in contact with the object to be conveyed M at a position higher than the center of gravity of the object to be conveyed M, and the second guide member 72 is arranged so as to be in contact with the object to be conveyed M at a position higher than its center of gravity. It is preferable to arrange them so that they are in contact with each other at a lower position. As a result, the object to be conveyed M is pushed in opposite directions at positions higher and lower than the center of gravity, so that the object to be conveyed M can be overturned just by conveying it a short distance. Combined with the fact that the first guide member 71 and the second guide member 72 approach toward the downstream side in the conveying direction, the first guide member 71 and the second guide member 72 move the object M to the center of gravity. Applying a moment of force about the position will easily tip over. At this time, the first guide member 71 moves the upper side of one side of the object M in contact with the first guide member 71 toward the inside (conveyance path side, rightward in FIG. 2). Then, the lower part of the other side surface of the object M in contact with the second guide member 72 is pushed inward (toward the transport path, leftward in FIG. 2). Then, the transferred object M is rotated (overturned).

As shown in FIGS. 2 and 5, the first guide member 71 and the second guide member 72 are arranged above and below the center of gravity of the object to be conveyed M, and are arranged in a figure of eight when viewed from above. is preferred. Further, the first guide member 71 maintains the height at which the transported object M is tilted and extends longer downstream than the second guide member 72 . As a result, even if the first guide member 71 causes the transported object M to fall toward the second guide member 72 , the transported object M does not ride up on the second guide member 72 .

Specifically, when the transported object M starts falling, the second guide member 72 presses the lower part of the side surface of the transported object. That is, the escaping movement of the lower part of the object M to be conveyed is restricted away from the first guide member 71, and the object M conveyed downstream is gradually brought closer to the first guide member 71 side (inside). . In addition, the first guide member also causes the upper side of the transferred object M to gradually approach the second guide member 72 side (inner side). Therefore, the transported object M reliably starts falling through the cooperation of the first guide member 71 and the second guide member. Here, further downstream, the second guide member 72 is shorter than the first guide member 71 and is discontinuous (see FIG. 5). Therefore, on the downstream side, the first guide member 71 extends further inward, causing the transported object M to fall further. Since the transported object M does not extend to the position where it intersects with the 2nd guide member 72, the overturned transported object M rides on the second guide member 72 and gets jammed, or is pinched vertically by the first guide member 71 and the second guide member 72 and gets jammed. There is no In addition, when the center of gravity of the object to be transported M inclines beyond the vertical position (side) of the installation point (side) of the object to be transported, the transported object M spontaneously falls over.

In addition, the first guide member 71 and the second guide member 72 are configured such that their crossing directions F1 and F2 are variable, and the positions of the first guide member 71 and the second guide member 72 are also variable. ing.

Specifically, the first guide member 71 is attached to the opposite side of the second guide member 72 via brackets 73 and 74 extending from the second guide member 72 side to the opposite side beyond the belt conveyor 40 . It is The brackets 73 and 74 are doubled above the belt conveyor 40 , one end of the bracket 73 is connected to the first guide member 71 and the other end of the bracket 74 is connected to the second guide member 72 . The interval between the first bracket 71 and the second bracket 72 can be adjusted via an elongated hole 75 in a direction perpendicular to the transport direction F provided in one bracket 73 .

Further, the second guide member 72 is inclined with respect to the conveying surface so that the surface of the second guide member 72 in contact with the object to be conveyed M (hereinafter referred to as the contact surface) extends inward from the bottom. As a result, the contact surface of the second guide member 72 contacts the transported object M in the upright state at a point (side). Therefore, the fulcrum (side) when tilted by the first guide member 71 becomes the lower end of the contact surface, and the vertical distance from the first guide member 71 is separated. becomes higher.

In FIGS. 3 and 4, a bracket that connects the bracket 74 and the mounting bracket 76 of the second guide member 72 is omitted from the drawings, but these brackets 74 and 76 are connected to the omitted portion. An L-shaped bracket is attached. Further, the crossing angle between the attachment position of the second guide member 72 and the conveying direction F can be adjusted through long holes 77 provided in the respective brackets 74 and 76 .

Also, the first guide member 71 is attached so as to be able to turn in a horizontal plane about a rotating shaft 78 provided on a horizontal portion 73a at the end of the bracket 73. As shown in FIG. Thereby, the first guide member 71 can change the crossing angle with the transport direction F. As shown in FIG. After the angle is adjusted, the first guide member 71 is fixed by a set screw (not shown) passing through the fan-shaped long hole 79 .

Further, these brackets 73, 74, and 76 are connected to a vertically movable post 80 so that the vertical positions of the first guide member 71 and the second guide member 72 can be adjusted simultaneously. In the figure, brackets for attaching these brackets 74 and 76 to the strut 80 are omitted from the figure. A horizontal guide rod 41 is also attached to the column 80 to prevent the object M from overturning.

The first guide member 71 and the second guide member 72 are each made of a nonmetallic material, specifically, a synthetic resin such as Duracon. Thus, even if a metal inspection machine is arranged downstream, these guide members 71 and 72 prevent the metal inspection machine from malfunctioning.

(Modification)
Although one embodiment of the present invention has been described above, the present invention is not limited to these embodiments. For example, in the above embodiment, the belt conveyor 40 of the transport section 4 is tilted so that the object to be transported M leans against the guide rod 71 side. You may make it convey the to-be-conveyed object M in an upright posture. In this case, the guide rod 42 may be extended to the position of the first guide member 71 so that the transported object M can be maintained in an upright position.

Further, in the above-described embodiment, the second guide member 72 is inclined toward the first guide member 71 side. The member 72 may be arranged parallel to the transport direction F (so that the contact surface extends normal to the transport surface). 5, the tip of the first guide member 71 is extended to the side edge of the belt conveyor 40, but instead of this, the tip of the first guide member 71 is stopped to approximately the center of the belt conveyor 40. , the tip portion of the second guide member 72 may be moved substantially to the center.

Hereinafter, based on FIG. 7, the attitude control device 7 according to the modified example of the above embodiment will be described.

The second guide member 72 may be configured to extend in the transport direction F, as shown in FIG. 7(a). In other words, the second guide member 72 does not have to be inclined toward the transport path (inward). In particular, when the conveyor 40 (conveying surface) is inclined with respect to the horizontal plane with the first guide rod 41 side facing downward, the object to be conveyed M can be conveyed on the second guide member 72 without particularly tilting the second guide member 72 inward. It contacts with the guide member 72 . Therefore, even if the second guide member 72 is configured to extend in the transport direction F, the second guide member 72 functions as a guide (functional part) for overturning the object M to be transported.

In FIG. 7A, the second guide rod 42 is indicated by a dotted line when the conveyor 40 (conveying surface) (not shown) is tilted with the first guide rod 41 side downward with respect to the horizontal plane. , the second guide rod 42 can be omitted, but if the conveyor 40 (conveying surface) is substantially horizontal, the position of the first guide member 71 is adjusted so that the object to be conveyed M can be kept standing. It shows that it can be extended to. That is, in FIG. 7A, the second guide rod 42 may or may not be arranged. The same applies to FIGS. 7B to 7D below.

Further, as shown in FIG. 7B, the first guide member 71 does not have to extend the imaginary straight line extending in the transport direction F from the upstream end of the second guide member 72 to the position of L1. This is effective when the object to be conveyed M is an article that tends to tip over, and if the first guide member 71 obstructs the path of the object to be conveyed M, the object to be conveyed M is jammed. Also in this case, in order to reliably overturn the transported object M, the upstream end of the first guide member 71 and the upstream end of the second guide member 72 must be separated from each other. , to the position of an imaginary straight line (the center line of the transport path) L0 extending in the transport direction.

In the above embodiment, as shown in FIG. 7C, the imaginary straight line extending in the transport direction F from the upstream end of the second guide member 72 is L1, and the upstream end of the first guide member 71 is L1. When an imaginary straight line extending from the part in the conveying direction F is L2, the angle θ1A formed between the first guide member 71 and the imaginary straight line L2 is set to be larger than the angle θ2A formed between the second guide member 72 and the imaginary straight line L1. was Furthermore, the first guide member 71 is configured to extend to the position of the imaginary straight line L1. However, as shown in FIG. 7D, even if the angle θ1B formed by the first guide member 71 and the virtual straight line L2 is smaller than the angle θ1B formed by the second guide member 72 and the virtual straight line L1, good. In this case, the lower side of the object to be conveyed M is pushed inward (to the right in FIG. 7(d)) mainly by the second guide member 72, and the bottom surface of the object to be conveyed M slides against the conveying surface (conveyor 40, not shown). You will fall.

7A to 7D, the second guide member 72 does not overlap (vertically) or intersect with the first guide member 71 in a substantially planar view. In other words, the downstream end of the second guide member 72 is separated from the first guide member 71 in a substantially plan view. Therefore, the conveyed object M that has started to fall does not ride on the second guide member 72 on the downstream side, and is not jammed by being vertically sandwiched between the first guide member 71 and the second guide member 72. . In addition, since a space in which the first guide member 71 and the second guide member 72 do not exist is generated in the spaced apart portion in a substantially plan view, a space for reliably contacting the conveying surface (conveyor 40 not shown) is secured, The object to be transported M is preferably transported downstream. Therefore, in order to turn over the object M, one side must be upside down while conveying the object M downstream without applying any external force other than the driving of the conveyor 40 (movement of the conveying surface). The side surface in contact with the first guide member 71 at a high position can be overturned.
