Description

  The present invention relates to a sorting device that sorts articles such as bottles and cans to be transported into a plurality of positions.

Conventionally, as an article distribution device arranged downstream of a quality inspection device (weight sorter, metal detector, X-ray inspection device, etc.),
(A) A pair of guides arranged opposite to each other in parallel to the conveying direction is provided above a belt conveyor for carrying and conveying a large number of articles, and the guides are swung in the same direction when the articles pass between them. That distributes to multiple positions (see Patent Document 1)
(B) As an application of the above (a), the article is sandwiched between a pair of drive belts from both sides, and the article is discharged by swinging the downstream roller of the drive belt in a direction perpendicular to the conveying direction. In this case, the upstream end of the sorting guide provided downstream thereof is swung in a direction orthogonal to the conveying direction to receive the article, and the article is distributed to a plurality of positions (see Patent Document 2).
(C) A connecting shaft of an endless track body that transports a large number of articles is provided with a plurality of transport bodies that are slidable in a direction orthogonal to the transport direction, and the placed articles are placed in a plurality of positions by sliding the transport bodies. (See Patent Document 3)
Various devices such as these are known.

In these sorting devices, the conveyance surface of the articles is always kept horizontal, and the sorting of the articles is also performed in the horizontal direction, so even if the article height is high such as a bottle or a can, There is no change in posture due to falling or the like at the time of sorting, which is convenient when a predetermined number of boxes are stored in a box or the like in a later process. In addition, when sorting the containers in which the articles are stored and opened, the sorting direction is horizontal and there is no change in the vertical behavior, so that the articles can be effectively sorted without spilling out.

  However, the sorting devices disclosed in Patent Documents 1 to 3 have the following problems.

  In the case of the sorting device disclosed in Patent Document 1, since the sorting direction of the article is regulated by a pair of guides, the guide tip must be moved to the target sorting position before the article has passed the guide. I must. Therefore, it is necessary to swing the pair of guides at a high speed, and further, since the load resistance of the article to be sandwiched is applied to the guides, a high speed and large capacity motor is required. In particular, when the guide is long, the load resistance due to the sorting of articles increases, so a motor with a larger capacity is required. On the other hand, if the guide is swung at a speed higher than a predetermined speed, there is a problem that due to the inertia, the article falls or the contents spill after sorting.

  In the case of the sorting device disclosed in Patent Document 2, since the structure in which the swinging device, the connection guide, and the division guide are interlocked with each other is employed, an increase in the size of the entire device is inevitable. Similarly to Patent Document 1, when an article is sandwiched between the guides of the swing device, a large-capacity motor corresponding to the load resistance is required. In particular, when the guide is long, the load resistance due to the sorting of articles increases, and a motor with a larger capacity is required. On the other hand, if the guide is swung at a speed higher than a predetermined speed, the article may fall down due to its inertia or the contents may spill even during the sorting process, so that guides on both sides of the article are essential during sorting. For this reason, an apparatus becomes complicated and it takes time for cleaning.

  In the case of the sorting device disclosed in Patent Document 3, the article is moved to the sorting position by sliding the carrier carrying the article, so that the speed is higher than when the guide is swung. Although it is possible to sort, it is necessary to move a large number of connecting shafts for transporting the transport body in the transport direction due to the mechanism of the apparatus, and the diameter of the sprocket is inevitably increased. For this reason, when sorting and transporting small articles, the size of the articles that can be sorted is reduced because they are sandwiched between the sorting apparatus and the upstream apparatus or downstream apparatus, or the articles fall over due to poor transfer. It was restricted. Also, since there are so many sliding parts, the noise is loud and the durability is poor.

  An object of the present invention is to provide a sorting device that enables high-speed sorting without complicating the structure and without disturbing the posture during and after sorting of articles.

The invention of claim 1 includes a conveyor that loads and conveys articles in the horizontal direction, and a distribution guide that is disposed above the conveyor and is inclined with respect to the conveyance direction of the article,
A sorting device that sorts the article into a plurality of sorting positions arranged in a horizontal direction by the sorting guide,
The sorting guide is composed of a pair of arms opposed to each other on a straight line, and an opening through which the opposite ends of the pair of arms swing in the opposite direction to form the opening and allow the article to pass therethrough. The article is distributed to a position and a side position where one side of the article is brought into contact with the sorting guide and the article is guided by the pair of arms being in a straight line. Providing the device.

Invention of Claim 2 is the distribution apparatus of Claim 1, Comprising:
The swinging of the opposing end swings to the acute angle side of the crossing angle of the article conveyance direction and the sorting guide.

Invention of Claim 3 is the distribution apparatus of Claim 1 or 2, Comprising:
There is provided a sorting apparatus characterized in that an intersection angle between the conveying direction of the article and the sorting guide is 30 degrees or less.

Invention of Claim 4 is the distribution apparatus in any one of Claim 1 to 3, Comprising:
The sorting guide is formed of a round bar, and provides a sorting device.

Invention of Claim 5 is the distribution apparatus in any one of Claim 1 to 4, Comprising:
According to the present invention, there is provided a sorting apparatus in which the swing of the sorting guide is completed before an article to be sorted reaches the opening.

Invention of Claim 6 is the distribution apparatus in any one of Claim 1 to 5, Comprising:
The sorting guide is arranged in a state of being suspended by a round bar from a frame arranged above the conveyor, and the sorting guide is separated from the conveyor by a predetermined distance by rotating one end of the frame upward. There is provided a sorting apparatus characterized by the above.

The invention of claim 7 is the sorting apparatus according to any one of claims 1 to 6,
Provided is a sorting apparatus including a plurality of sorting guides along the transport direction, and a plurality of openings of the plurality of sorting guides arranged in a straight line along the transport direction. .

  According to the sorting device of the first aspect, when sorting the articles to the side position, since only one sorting guide is brought into contact with one side surface of the article, the sorting guide is simplified. Can be configured. Moreover, when the article is distributed to the opening position, the distribution guide is divided into two short arms to form the opening, so that the inertia weight at the time of swinging is reduced, and the sorting guide is swung at high speed. In addition, driving with a small-capacity driving source is possible.

  According to the sorting apparatus of the second aspect, the sorting guide swings to the acute angle side of the intersection angle with the conveying direction of the conveyor, so that the swinging can be completed in a short time.

  According to the sorting device of the third aspect, since the sorting guide has an inclination angle of 30 degrees or less, when the article is guided to the side position by the sorting guide, the article hits the guide at a relatively high speed. Even if it comes into contact, it can be prevented from bouncing back, and the posture of the article can be prevented from changing or the contents can be prevented from spilling.

  According to the sorting apparatus of the fourth aspect, since the sorting guide is formed of a round bar, the contact area in contact with the article is small, and as a result, a reduction in sorting speed due to contact resistance can be prevented.

  According to the sorting device of the fifth aspect, since the swing of the sorting guide is completed before the article to be sorted reaches the opening, compared with the case where the arm is swung in the middle of sorting the article. Thus, the load resistance applied to the arm is small, and high-speed distribution is possible. In addition, it is possible to prevent flipping of the article due to swinging of the sorting guide during the sorting of the article. In particular, when the non-defective product is distributed to the opening position, the article does not contact the sorting guide, so that even if it is sorted at a high speed, the article (good product) is not affected.

  According to the sorting device of the sixth aspect, during operation, the sorting guide is operated in a suspended state from above, and during cleaning and maintenance work, the frame is rotated to be separated from the conveyor by a predetermined distance. Therefore, cleaning and maintenance work is easy to perform.

  According to the distribution device of the seventh aspect, distribution in multiple directions of three directions or more is possible, and a plurality of openings are on a straight line. By doing so, high-speed distribution becomes possible.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

One end of the frame 31 is rotatably supported by a hinge 31a, and the other end is fixed by a buckle-shaped lock member 31b so as to be unlockable. Therefore, the frame 31 is separated from the conveyor 22 by a predetermined distance as shown by a two-dot chain line in FIG. 3 by unlocking the lock member 31b and rotating upward about the hinge 31a. It can be. The frame 31 is provided with a handle 31c on the side surface on the free end side for facilitating lifting during the turning operation, and the frame 31 is turned upward in the vicinity of the hinge 31a. A lock plate 31d for locking and supporting is attached.

(Distribution guide 32)
As shown by a two-dot chain line in FIG. 2, the distribution guide 32 is inclined with respect to the conveying direction of the article G (the direction of the arrow X2) with a crossing angle θ1 of 30 degrees or less in the horizontal direction. A pair of arms 321 and 322 formed by the above are arranged so as to face each other in a straight line. The arms 321 and 322 are set to a height at which the arms 321 and 322 abut on the side surface of the article G conveyed on the conveyor 22. In addition, the opposite ends 321b and 322b of the arms 321 and 322 (see FIG. 3) are arranged so that the opposite ends 321a and 322a can swing in the horizontal direction. Are fixedly supported at the lower ends of the round bars 341 and 342. In FIG. 3, parts of the distribution guide 32 and the drive mechanism 34 are hidden behind the distribution guide 33 and the drive mechanism 35, which will be described later. Corresponding reference numerals are enclosed in parentheses after the reference numerals.

  The drive mechanism 34 is supported by the frame 31 so as to be freely rotatable and hangs down, rod-shaped link members 343 connecting the brackets 341a and 342a fixed to the upper ends thereof, and the round bar 341. A driving stepping motor 344 is provided. The link member 343 is provided so that the round bars 341 and 342 always rotate in the same direction. As shown in FIG. 2, when the round bar 341 is rotated in the counterclockwise direction, the round bar 342 is provided. Is also designed to rotate counterclockwise. Driving force is transmitted to the round bar 341 via a pulley 341b provided on the upper end side thereof, a pulley 344b provided on a driving shaft of the stepping motor 344, and a driving belt 345 wound around these pulleys.

  Therefore, when the round bars 341 and 342 are rotated in the same direction by the stepping motor 344 serving as a driving source, the arms 321 and 322 have their opposite ends 321a and 322a swinging in the opposite directions so that they are parallel to each other. And a position (position indicated by a solid line in FIG. 2) and a position where the opposing ends 321a and 322a are aligned with each other in a straight line (position indicated by a two-dot chain line in FIG. 2), It can swing. Here, as indicated by arrows R1 and R2, the opposing ends 321a and 322a are set so as to swing to the acute angle direction side of the crossing angle between the conveyance direction of the article G and the sorting guide 32.

  When the opposing ends 321a and 322a are separated from each other, as shown in FIG. 4B or FIG. 4C, an opening 32A is formed, and the article G conveyed on the conveyor 22 is passed. When the opposed ends 321a and 322a are close to each other, the one side of the article G transported on the transport conveyor 22 is used as a sorting guide, as shown in FIG. 4A. By abutting, the article G is distributed to the side position B (distribution position B) that guides the article G. The swinging of the opposite ends of the arms 321 and 322 is set to be completed before the article to be distributed reaches the opening 32A.

(Distribution guide 33)
As shown by a two-dot chain line in FIG. 2, the distribution guide 33 is inclined in the opposite direction with the same crossing angle θ1 as the distribution guide 32 in the horizontal direction with respect to the conveyance direction (arrow X2 direction) of the article G. It is configured by arranging a pair of arms 331 and 332 formed by round bars so as to face each other in a straight line. Similarly to the arms 321 and 322, the arms 331 and 332 are set to a height that abuts against the side surface of the article G to be conveyed, and the opposite ends 331a and 332a can swing so that the opposite ends 331a and 332a can swing. Rotating end portions 331b and 332b (see FIG. 3) are fixedly supported on lower ends of round bars 351 and 352 that are drive shafts of the drive mechanism 35.

  The drive mechanism 35 is configured in the same manner as the drive mechanism 34, and includes round bars 351 and 352 that are rotatably supported by the frame 31, a rod-shaped link member 353 that connects these upper end side brackets, and a round shape. A stepping motor 354 for rotating the rod 351 is provided. Like the link member 343, the link member 353 is provided so that two round bars always rotate in the same rotation direction.

  Therefore, when the round bar 351 is rotated by the stepping motor 354, the opposite ends 331a and 332a are swung in the opposite directions so that the arms 331 and 332 are separated from each other in parallel (see solid lines in FIG. 2). 2) and the positions where the opposite ends 331a and 332a are close to each other and are aligned in a straight line (the position indicated by the two-dot chain line in FIG. 2). . Here, as indicated by arrows R 3 and R 4, the opposed ends 331 a and 332 a are set so as to swing to the acute angle direction side of the crossing angle between the conveyance direction of the article G and the sorting guide 33.

  The distribution guide 33 is provided on the downstream side of the distribution guide 32, and both openings 32A and 33A are arranged in a straight line along the transport direction X2, as shown in FIG. 4B. Therefore, the article G guided to the opening position A of the distribution guide 32 is further guided to the opening position C (distribution position C) or the side position D (distribution position D) of the distribution guide 33. It will be possible. The swinging of the opposite ends of the arms 331 and 332 is set to be completed before the article to be distributed reaches the opening 33A.

  When the opposed ends 331a and 332a are separated from each other, an opening 33A is formed as shown in FIG. 4B, and the article G that has passed through the opening 32A abuts against the distribution guide. Without being guided to the distribution position C. Further, when the opposite ends 331a and 332a are close to each other, as shown in FIG. 4C, the article G that has passed through the opening 32A comes into contact with the sorting guide 33 so that one side thereof contacts the sorting guide 33. It will be guided to position D.

  As described above, the article G can be distributed to any one of the distribution positions B, C, and D by the operation of the distribution guides 32 and 33. Note that fixed guides 36, 37, 38, and 39 formed of round bars are provided on both sides of the distribution positions B and D so as not to deviate from the course on which the article G is conveyed. These fixed guides are suspended from the frame 31 by round bars so as to have the same height as the distribution guides 32 and 33.

(Operation of the above embodiment)
Next, the operation of the above-described embodiment will be described.

  In the quality inspection apparatus 1, when the article G determined to be excessive is conveyed to the sorting apparatus 2, the sorting apparatus 2 performs the process shown in FIG. 4 (a) based on the instruction signal from the quality inspection apparatus 1. As shown, the arms 321 and 322 of the sorting guide 32 are swung to positions aligned on a straight line. As a result, the article G conveyed on the conveyor 22 is distributed to the distribution position B with one side surface being brought into contact with the distribution guide. In FIG. 4A, the arms of the sorting guide 33 are arranged in a straight line, but may be swung so as to form an opening.

  When the article G determined to be lightweight in the quality inspection apparatus 1 is conveyed to the sorting apparatus 2, the sorting apparatus 2 displays the information shown in FIG. 4 (b) based on the instruction signal from the quality inspection apparatus 1. As shown, the arms 321 and 322 of the sorting guide 32 are swung so as to form the opening 32A, and the arms 331 and 332 of the sorting guide 33 are swung so as to form the opening 33A. . As a result, the article G conveyed on the conveyor 22 is passed through the opening 32A and guided to the opening position A, and then further passed through the opening 33A to be opened at the opening position C (distribution position C). Will be distributed.

  In the quality inspection apparatus 1, when the article G determined to be a positive amount is conveyed to the sorting apparatus 2, the sorting apparatus 2 performs the processing shown in FIG. 4 (c) based on the instruction signal from the quality inspection apparatus 1. As shown in FIG. 4, the arms 321 and 322 of the sorting guide 32 are swung so as to form the opening 32A, and the arms 331 and 332 of the sorting guide 33 are swung to positions aligned on a straight line. As a result, the article G transported on the transport conveyor 22 passes through the opening 32A and is guided to the opening position A, and then, one side surface thereof is brought into contact with the sorting guide 33 so that the sorting position D is reached. Will be distributed.

  That is, the article G inspected by the quality inspection apparatus 1 is allocated to any of B (overweight), C (light weight), and D (positive amount) by the distribution apparatus 2 based on the quality inspection result. After that, the processing work corresponding to the inspection result is performed in the subsequent process. Specifically, the article G distributed to the distribution position B or the distribution position C is conveyed to a reworking process for increasing or decreasing the amount of food inside the can, and the article G distributed to the distribution position D is left as it is. It is conveyed to the can sealing process.

(Features of sorting device 2)
The distribution device 2 according to the embodiment has the following characteristic points.

  First, according to the sorting device 2, when sorting the article G to the lateral position B or D, it is only necessary to contact one sorting guide 32 or 33 on one side of the article G. The distribution guides 32 and 33 can be configured simply. Moreover, when the article G is distributed to the opening positions A and C, the distribution guide 32 or 33 is divided into two short arms 321, 322 or 331, 332 to form the openings 32A or 33A. The inertia weight at the time of swinging can be reduced. As a result, the sorting guide can be swung at high speed to increase the speed of the sorting process, and the capacity of the stepping motors 344 and 354 can be reduced.

  Second, according to the sorting apparatus 2, the sorting guides 32 and 33 swing to the acute angle θ1 direction side of the crossing angle with the transport direction of the transport conveyor 22, so that swinging is completed in a short time. It can be made to. As a result, the distribution process can be further speeded up.

  Thirdly, according to the sorting device 2, since the inclination angle θ1 of the sorting guides 32 and 33 is 30 degrees or less, when the article G is guided to the lateral position B or D by the sorting guides 32 and 33, Even when the article G abuts the sorting guide at a relatively high speed, the incident angle becomes small, and it is possible to prevent the article G from bouncing back. As a result, it is possible to prevent the posture of the article G from changing (falling, tilting, or swinging), and thereby preventing food that has been put into the can from being spilled on the conveyor 22.

  Fourthly, according to the sorting device 2, the sorting guides 32 and 33 are formed of round bars, so that the contact area with which the article G comes into contact is small. As a result, it is possible to prevent the sorting speed from being lowered by the contact resistance when the article G is guided to the side position. Since the fixed guides 36, 37, 38, 39 are also formed of round bars, there is little resistance when they are in contact with the article G, and the article G can be transported smoothly.

  Fifthly, according to the sorting device 2, the swinging of the sorting guides 32 and 33 is completed before the sorted article G reaches the openings 32A and 33A. Compared with the case of rocking, the load resistance applied to the arm is less and high-speed sorting becomes possible. In addition, it is possible to prevent the article from being flipped by swinging the sorting guides 32 and 33 while the article G is being distributed. In particular, if a correct amount of the article G (non-defective product) is distributed to the opening position, the article G does not contact the sorting guide, and therefore the article G is not affected at all even if it is sorted at a high speed.

  Sixth, according to the distribution device 2, the distribution guides 32 and 33 are operated in a suspended state from above during the operation thereof, and the frame is rotated during cleaning and maintenance work to be predetermined from the conveyor. Since the distance is separated, cleaning and maintenance work can be easily performed. In addition, since the distribution guides 32 and 33 and the members for suspending the distribution guides 32 and 33 are formed of round bars, cleaning work such as wiping off dirt can be easily performed.

  Seventhly, according to the sorting apparatus 2, since the two (plurality) sorting guides 32 and 33 are provided, sorting in three or more directions becomes possible. Further, since the two (plurality) openings 32A and 33A are provided in a straight line, if the distribution position of the correct amount of the article G (non-defective product) is C at the downstream of the opening, the distribution is performed. There is no worry of the contents spilling due to external force applied to the non-defective product on the way, and high-speed sorting is possible.

(Modification of the above embodiment)
In the above-described embodiment, the quality inspection apparatus 1 arranged upstream of the sorting apparatus 2 determines whether the weight of the article G is within the target weight range, or is lighter or more than that. However, the present invention is not limited to this, and a metal detection device, an X-ray inspection device, or the like for determining whether or not foreign matter is mixed in the article is arranged, and the article is determined based on the determination result. G may be divided into a non-defective product and a defective product.

  In the above-described embodiment, the article G to be distributed is one in which food is introduced into the inside of the can whose upper part is opened, but not limited to this, when being conveyed on the conveyor, As long as the article can be guided to the side by abutting against the sorting guide, it may be an article such as a box, a bottle, or a bag.

  In addition, the distribution device of the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the scope of the present invention.
