Detailed Description

Hereinafter, an embodiment of the conveying device will be described with reference to fig. 1 to 14. Note that, in each drawing (the same applies to fig. 15 and 16), the dimensional ratio and the actual dimensional ratio in the drawings do not necessarily coincide, and the dimensional ratio between the drawings does not necessarily coincide.

As shown in fig. 1, a conveying apparatus 1 according to the present embodiment is provided in a processing apparatus 10, the processing apparatus 10 being used to accommodate a plurality of articles 12 in an object 11. Therefore, before explaining the respective arrangements of the transport apparatus 1, the processing apparatus 10 will be explained.

The processing apparatus 10 includes: a supply section 13 for supplying the article 12; an upstream conveying section 14 for conveying the object 11 from upstream to the conveying device 1; and a downstream conveying section 15 for conveying the object 11 downstream from the conveying device 1. Furthermore, the processing apparatus 10 further includes: a conveying unit 16 that conveys the article 12 on the supply unit 13 to the object 11 on the conveying device 1; and a frame 17 that supports the transport device 1 and the conveyance unit 16.

The object 11 is, for example, a box with an open upper side, and in the present embodiment, is provided as a box formed of plastic or cardboard. The object 11 has a long side direction and a short side direction, and is formed in a rectangular shape in plan view (as viewed from the third direction D3), for example. The article 12 is, for example, a container containing contents, and in the present embodiment, is set as a container containing eggs therein. It is noted that the object 11 and the article 12 are not limited to this configuration.

Further, the first direction D1 and the second direction D2 are horizontal directions (lateral directions), respectively, and the first direction D1 is a direction orthogonal to the second direction D2. The third direction D3 is a vertical direction (vertical direction), i.e., a direction orthogonal to the first direction D1 and the second direction D2, respectively.

The conveying device 1 includes: a stop unit 2 that stops a plurality of objects 11 arranged in parallel in a first direction D1; a first conveyance unit 3 provided upstream of the stop unit 2; and a second conveyance unit 4 provided downstream of the stop unit 2. In the present embodiment, the stopping unit 2 is configured to stop the two objects 11 arranged in parallel in the first direction D1, but is not limited to this arrangement. For example, it may be configured such that three or more objects 11 are juxtaposed and stopped in the first direction D1.

The supply section 13 includes: an article conveyance body 13a for conveying the article 12 in a first direction D1; and a stopping device 13b for stopping the article 12 on the article conveying body 13 a. The supply unit 13 stops the articles 12 as necessary by the stop device 13b to generate a space between the

articles

12 and 12, and conveys the articles 12 in order in the first direction D1.

The downstream end portion of the upstream conveying portion 14 is adjacent to the end portion of the first conveying portion 3 in the first direction D1. Thereby, the upstream conveying unit 14 conveys the object 11 having an empty interior toward the first conveying unit 3, and carries the object 11 into the first conveying unit 3. In the present embodiment, the upstream conveying portion 14 conveys the object 11 in the first direction D1.

The upstream end portion of the downstream conveying portion 15 is adjacent to the end portion of the second conveying portion 4 in the first direction D1. Thereby, the downstream conveying section 15 carries out the object 11 in which the article 12 is accommodated from the second conveying section 4, and conveys the carried-out object 11 to the downstream. In the present embodiment, the downstream conveying portion 15 conveys the object 11 in the first direction D1.

The conveying unit 16 includes: two

manipulators

16a, 16a with six degrees of freedom; and

suction portions

16b, 16b provided at the tip of each robot arm 16a for sucking the article 12. The suction unit 16b sucks the plurality of articles 12 on the supply unit 13, and the robot 16a operates to convey the plurality of articles 12 into the object 11 stopped on the stop unit 2 of the conveyor 1.

As shown in fig. 2 to 4, the first conveying section 3 includes a first conveyance body 3a that conveys the object 11 in the first direction D1. The first conveyance body 3a includes a plurality of rollers that rotate about axes in the second direction D2. Thus, the first conveyance body 3a conveys the object 11 in the first direction D1 in a state of being placed on the plurality of rollers by the rotation of the plurality of rollers.

The second conveyance section 4 includes a second conveyance body 4a that conveys the object 11 in the first direction D1. The second conveyance body 4a includes a plurality of rollers that rotate about axes in the second direction D2. Thus, the second conveyance body 4a conveys the object 11 in the first direction D1 in a state of being placed on the plurality of rollers by the rotation of the plurality of rollers. The first direction D1 in which the second conveying unit 4 conveys the object 11 is opposite to the first direction D1 in which the first conveying unit 3 conveys the object 11.

Further, the first conveying section 3 is adjacent to the stopping section 2 on the upstream side in the second direction D2, and the second conveying section 4 is adjacent to the stopping section 2 on the downstream side in the second direction D2. Therefore, the stop portion 2 is disposed between the first conveying portion 3 and the second conveying portion 4 in the second direction D2.

The first conveying unit 3 and the second conveying unit 4 are formed in a size capable of placing a plurality of objects 11 thereon. The first conveying unit 3 and the second conveying unit 4 are sized to be capable of placing at least the number of objects 11 (two

objects

11, 11 in the present embodiment) that can be stopped at the stopping unit 2. Specifically, the first and

second conveyors

3 and 4 have a size in the first direction D1 that is equal to or larger than the size of the stopper 2 in the first direction D1. The first conveying unit 3 and the second conveying unit 4 are arranged to overlap the entire stopping unit 2 in the second direction D2.

The stop portion 2 includes: a moving section 2a that moves the object 11 in the second direction D2; and a guide section 2b for guiding the moving object 11. The moving unit 2a includes a plurality of rollers that rotate about the first direction D1. Thereby, the moving portion 2a moves the object 11 in the second direction D2 in a state of being placed on the plurality of rollers by the rotation of the plurality of rollers.

Further, the conveying device 1 includes: and a loading unit 5 that loads the object 11 from the first conveying unit 3 to the stopping unit 2. Specifically, the first conveying section 3 includes a first movement assisting section 3b for assisting the movement of the object 11 in the second direction D2, and the carry-in unit 5 is constituted by the moving section 2a of the stop section 2 and the first movement assisting section 3b of the first conveying section 3.

Further, the conveying device 1 includes: and a carrying-out unit 6 that carries out the object 11 from the stopping unit 2 to the second conveying unit 4. Specifically, the second conveying section 4 includes a second movement assisting section 4b for assisting the movement of the object 11 in the second direction D2, and the carry-out unit 6 is constituted by the moving section 2a of the stop section 2 and the second movement assisting section 4b of the second conveying section 4.

The first movement assisting section 3b is configured to push the object 11 in the second direction D2 to place a part of the object 11 on the first conveying section 3 on the moving section 2 a. For example, the first movement assisting portion 3b includes an abutting portion that comes into contact with the object 11 and an operating portion that moves the abutting portion in the second direction D2.

Therefore, a part of the object 11 is placed on the moving portion 2a by the first movement assisting portion 3b pushing the object 11 on the first conveying portion 3 in the second direction D2. Then, the object 11 is moved in the second direction D2 by the rotation of the rollers of the moving portion 2a, and thereafter, the object 11 is stopped at a predetermined position of the stopping portion 2 by stopping the rotation of the rollers of the moving portion 2 a. Therefore, the carrying-in unit 5 carries the object 11 from the first conveying section 3 to the stopping section 2 by the cooperation of the moving section 2a and the first movement assisting section 3 b.

The second movement assisting section 4b is configured to smoothen the movement of the object 11 on the second conveying section 4 in the second direction D2. For example, the second movement assisting section 4b may be configured such that a plurality of rollers rotating about the first direction D1 are arranged in parallel in the second direction D2 and are displaceable in the vertical direction (third direction) D3 with respect to the second conveyance body 4 a.

Thus, in a state where the second movement assisting section 4b is positioned above the second conveying body 4a, the object 11 on the stopping section 2 is moved in the second direction D2 by the rotation of the rollers of the moving section 2a and placed on the second movement assisting section 4 b. In this way, the moving section 2a and the second movement assisting section 4b cooperate with each other, and the carrying-out unit 6 carries out the object 11 from the stopping section 2 to the second conveying section 4. In addition, when the second conveyance body 4a conveys the object 11 in the first direction D1, the second movement assisting section 4b is located below the second conveyance body 4 a.

The stopping unit 2 includes two stopping

spaces

2c and 2c for stopping the two

objects

11 and 11, respectively. Also, the dimension W2 in the second direction D2 of the stopping space 2c is smaller than the dimension W1 in the first direction D1. Therefore, when the object 11 is stopped at the stop 2, the short side direction of the object 11 is along the second direction D2, and the long side direction of the object 11 is along the first direction D1. Note that the stop space 2c is an area where the object 11 can be placed.

In the present embodiment, the first direction D1 of the stopping space 2c is defined by a pair of

guide portions

2b, 2 b. Therefore, the dimension of the stopping space 2c in the first direction D1 is the distance between the pair of

guide portions

2b, 2b arranged apart in the first direction D1.

In the present embodiment, the second direction D2 of the stopping space 2c is defined by rollers arranged at the end in the second direction D2 in the moving section 2 a. Therefore, the dimension of the stopping space 2c in the second direction D2 is the distance between the axial centers of the rollers arranged at the ends of the second direction D2.

Note that the friction coefficient of the moving section 2a with respect to the object 11 is larger than the friction coefficients of the first and second conveying

bodies

3a and 4a with respect to the object 11, respectively. For example, the outer periphery of the roller of the moving portion 2a is formed of a material (e.g., rubber) having a large friction coefficient with respect to the object 11.

The configuration of the transport apparatus 1 according to the present embodiment is as described above, and next, the operation of the transport apparatus 1 according to the present embodiment will be described with reference to fig. 5 to 14. Note that in fig. 5 to 14, for the sake of easy understanding of the relationship of the object 11, the symbols for the object 11 are distinguished using 11a to 11 g.

First, a conveying device X1 according to a first comparative example will be described with reference to fig. 5 and 6. The conveyor device X1 according to the first comparative example is arranged in a linear shape in the order of the first conveyor unit X3, the stop unit X2, and the second conveyor unit X4 from the upstream side. Further, the first conveyance unit X3, the stop unit X2, and the second conveyance unit X4 are arranged to convey the object 11 in the first direction D1, respectively.

As shown in fig. 5, the two

objects

11a and 11b are juxtaposed and stopped in the first direction D1 at the stop portion X2. Then, when the processing of the

objects

11a and 11b stopped at the stop section X2 is completed, the first conveyance section X3, the stop section X2, and the second conveyance section X4 convey the objects 11a to 11f in the first direction D1 as shown in fig. 6.

At this time, the

objects

11a and 11b, which have been processed at the stop section X2, move only by the predetermined distance S1 from the stop section X2 to the second conveyance section X4, and the

objects

11c and 11d to be newly processed move only by the predetermined distance S1 from the first conveyance section X3 to the stop section X2. In such a configuration, the predetermined distance S1 is approximately twice the distance of the object 11.

Therefore, the time corresponding to this distance S1 is the switching time of the object 11 in the stopping portion 2. In addition, in the conveying device X1 according to the first comparative example 1, the switching time of the objects 11 at the stop section 2 becomes longer in proportion to the number of the objects 11 stopped at the stop section X2 (for example, becomes three or more and the number becomes larger).

Hereinafter, the conveying device 1 according to the present embodiment will be explained with reference to fig. 7 to 10. In the conveying device 1 according to the present embodiment, as shown in fig. 7, the first conveying section 3 is adjacent to the stop section 2 on the upstream side in the second direction D2, and the second conveying section 4 is adjacent to the stop section 2 on the downstream side in the second direction D2. Also, the two

objects

11a and 11b are juxtaposed and stopped in the first direction D1 at the stop portion 2.

Thereafter, when the processing of the

objects

11a, 11b stopped at the stopping portion 2 is completed, as shown in fig. 8, the

objects

11a, 11b stopped at the stopping portion 2 are moved together in the second direction D2 by the moving portion 2a and the second movement assisting portion 4b (not only simultaneously but also including parallel movement to some extent). Further, the objects 11c and 11D waiting at the first conveying section 3 are moved together in the second direction D2 (not only simultaneously but also to some extent in parallel) by the moving section 2a and the first movement assisting section 3 b.

Then, as shown in fig. 9, the

objects

11a and 11b that have been processed at the stop section 2 are moved from the stop section 2 to the second conveyance section 4 by only a predetermined distance S2, along with which the

objects

11c and 11d to be newly processed are moved from the first conveyance section 3 to the stop section X2 by only a predetermined distance S2. In such a configuration, the predetermined distance S2 is a distance that is approximately one time of the object 11, specifically, a distance that is approximately one time of the dimension in the short side direction of the object 11. Therefore, the time corresponding to the distance S2 is the switching time of the object 11 at the stopping portion 2.

Thus, the switching time of the object 11 on the conveyor 1 according to the present embodiment is significantly shorter than that of the object 11 on the conveyor X1 according to the comparative example. It should be noted that, on the conveying device 1 according to the present embodiment, the switching time of the objects 11 at the stopping portion 2 is constant regardless of the number of the objects 11 stopped at the stopping portion 2, that is, even if the number of the objects 11 stopped at the stopping portion 2 increases.

However, the friction coefficient of the moving portion 2a with respect to the object 11 is larger than the friction coefficients of the first and

second conveyors

3a and 4a with respect to the object 11, respectively. Thus, when the object 11 is carried from the first conveying unit 3 to the stopping unit 2, the object 11 can be smoothly carried in, and the object 11 can be stopped at a desired position of the stopping unit 2.

For example, when the friction coefficient of the moving portion 2a with respect to the object 11 is small, the object 11 may slide on the stopping portion 2 and stop at a position beyond a desired position. In addition, when the moving speed of the object 11 is slowed to prevent this phenomenon from occurring, although the object 11 can be stopped at a desired position, the moving time of the object 11 becomes long.

Further, when the object 11 is carried out from the stopping section 2 to the second conveying section 4, the object 11 can be smoothly carried out. For example, when the friction coefficient of the moving portion 2a with respect to the object 11 is small, the object 11 slides on the stopping portion 2, and therefore the moving time of the object 11 may become long. In addition, if the moving speed of the object 11 is reduced to prevent this phenomenon, the moving time of the object 11 becomes longer.

Further, thereafter, as shown in fig. 10, upstream conveying section 14 and first conveying section 3 convey objects 11e to 11g in first direction D1, and second conveying section 4 and downstream conveying section 15 convey

objects

11a, 11b in first direction D1. This causes the same state as fig. 7.

In this way, since the plurality of objects 11 can be juxtaposed and stopped at the stopping portion 2 in the first direction D1, the plurality of objects 11 stopped at the stopping portion 2 can be simultaneously processed. Therefore, for example, the productivity of the processing apparatus 10 can be improved. Further, since the time for switching the object 11 in the stop unit 2 can be shortened, the throughput of the processing apparatus 10 can be further improved.

Next, a conveying device X1 according to a second comparative example will be explained with reference to fig. 11 to 14. The conveyor device X1 according to the second comparative example is configured to: one of the first conveying section X3 and the second conveying section X4 is adjacent to the stop section 2 in the second direction D2, and the other is adjacent to the stop section 2 in the first direction D1 (arranged linearly with the stop section 2).

The conveyor device X1 according to fig. 11 is configured to: the first conveying section X3 is adjacent to the stop section X2 in the second direction D2, and the second conveying section X4 is adjacent to the stop section X2 in the first direction D1 (arranged linearly with the stop section X2). According to such a configuration, as shown in fig. 12, the

objects

11a and 11b that have been processed at the stop X2 move at least about twice the distance of the object 11 from the stop X2 to the second conveyance part X4.

Next, after the

objects

11a and 11b are completely carried out from the stop portion X2, the

objects

11c and 11d to be newly processed move from the first conveying portion X3 to the stop portion X2 by about one time the distance of the objects 11. Therefore, the switching time of the object 11 in the conveyor device X1 according to fig. 11 and 12 is longer than the switching time of the object 11 according to the first comparative conveyor device X1.

Furthermore, the transport device X1 according to fig. 13 is configured to: the first conveyance unit X3 is adjacent to the stop unit X2 (arranged linearly with the stop unit X2) in the first direction D1, and the second conveyance unit X4 is adjacent to the stop unit X2 in the second direction D2. According to such a configuration, as shown in fig. 14, the

objects

11a and 11b that have been completed in the stop section X2 move from the stop section X2 to the second conveyance section X4 by a distance approximately twice that of the object 11.

Next, after the

objects

11a and 11b are completely carried out from the stop portion X2, the

objects

11c and 11d to be newly processed move from the first conveying portion X3 to the stop portion X2 by a distance approximately twice as long as the objects 11. Therefore, the switching time of the object 11 in the conveyor device X1 according to fig. 13 and 14 is longer than the switching time of the object 11 according to the first comparative conveyor device X1.

As described above, the conveying apparatus 1 according to the present embodiment includes the stop portion 2 that stops the plurality of objects 11 being juxtaposed in the first direction D1, and the first conveying portion 3 and the second conveying portion 4 that convey the objects 11 in the first direction D1, and the first conveying portion 3 is adjacent to the stop portion 2 on one side in the second direction D2 orthogonal to the first direction D1 so that the plurality of objects 11 are moved together from the first conveying portion 3 to the stop portion 2, and the second conveying portion 4 is adjacent to the stop portion 2 on the other side in the second direction D2 so that the plurality of objects 11 are moved together from the stop portion 2 to the second conveying portion 4.

According to such a configuration, the first conveyance section 3 is adjacent to the stop section 2 on the side in the second direction D2 orthogonal to the first direction D1. Therefore, the plurality of objects 11 can be moved from the first conveying section 3 to the stopping section 2 by being moved together in the second direction D2 after being conveyed in the first direction D1 by the first conveying section 3.

The second conveying unit 4 is adjacent to the other side of the stop unit 2 in the second direction D2. As a result, the plurality of objects 11 can be moved together in the second direction D2 from the stopper 2 to the second conveying unit 4, and thereafter, can be conveyed in the first direction D1 by the second conveying unit 4.

Therefore, for example, the plurality of objects 11 processed at the stopping unit 2 can be switched by moving the objects 11 by a distance S2 of about one time as long as the objects 11 are moved from the stopping unit 2 to the second conveying unit 4, and the plurality of objects 11 to be newly processed by moving the objects 11 by a distance S2 of about one time as long as the objects 11 are moved from the first conveying unit 3 to the stopping unit 2. In this way, since the time for the object 11 to move by the distance S2 that is about one time the object 11 is the switching time of the object 11, the switching time of the object 11 at the stop portion 2 can be shortened.

Further, the conveying apparatus 1 according to the present embodiment is configured such that: the stopping portion 2 includes a plurality of stopping spaces 2c that respectively stop the plurality of objects 11, and a dimension W2 in the second direction D2 of the stopping spaces 2c is smaller than a dimension W1 in the first direction D1.

According to such a configuration, in the stopping portion 2, the dimension W2 in the second direction D2 of the stopping space 2c where the object 11 is stopped is smaller than the dimension W1 in the first direction D1. Thus, for example, the short-side direction of the object 11 stopped in the stopping space 2c is set in the second direction D2, and the long-side direction of the object 11 is set in the first direction D1, so that the time for which the object 11 moves only a distance of about one time the size in the short-side direction of the object 11 is the switching time of the object 11. Therefore, the switching time of the object 11 at the stop portion 2 can be further shortened.

Further, the conveying apparatus 1 according to the present embodiment is configured such that: the first conveyance section 3 includes a first conveyance body 3a that conveys the object 11 in the first direction D1, the second conveyance section 4 includes a second conveyance body 4a that conveys the object 11 in the first direction D1, and the stop section 2 includes a moving section 2a that moves the object 11 in the second direction D2, and a friction coefficient of the moving section 2a with respect to the object 11 is larger than friction coefficients of the first conveyance body 3a and the second conveyance body 4a with respect to the object 11, respectively.
