(conveyance device)

Fig. 1 is a side view showing a schematic configuration of a transport apparatus 1 according to embodiment 1. Fig. 2 is a plan view of the conveyance jig 10 for conveying the conveyed object. Fig. 3 is a view schematically showing a state where the objects M1 and M2 are held by the holding portion 11 of the conveyance jig 10. Fig. 4 is a cross-sectional view taken along line IV-IV in fig. 1, and is a view showing a schematic configuration of the supply unit 40 that supplies the objects M1 and M2 to the jig 10 for conveyance.

First, the structure of the transport apparatus 1 will be described with reference to fig. 1 to 4. The conveying device 1 is a device for conveying the conveyed objects M1, M2 in the conveying direction by pushing them with the conveying jig 10. Specifically, as shown in fig. 1, the conveying device 1 includes a conveying jig 10, a base portion 20, a supply portion 40, a position sensor 50, a control portion 70, and a jig driving portion 80.

In the present embodiment, the objects to be transported M1 and M2 are permanent magnets having a rectangular parallelepiped shape. The shapes of the conveyances M1 and M2 are different. The length of the short side direction of the conveyance object M1 is shorter than the length of the short side direction of the conveyance object M2 when viewed from above. The conveying device 1 of the present embodiment simultaneously conveys two conveyed objects M1 and one conveyed object M2 by using the conveying jig 10.

The base portion 20 has a flat plate shape. The supply unit 40 and the jig driving unit 80 are fixed to the base unit 20. The base part 20 includes a flat plate-like conveyance table 21 and a flat plate-like cover part 22. The conveying table 21 and the cover 22 may be different members or may be one member.

The conveyance table 21 is made of a magnetic material. The conveying table 21 has a groove 20a extending in one direction on an upper surface. Cover 22 is positioned above groove 20a and covers groove 20 a. Thus, the base portion 20 has a space 20b formed by the groove 20a and the cover portion 22 and extending in one direction. The conveyance jig 10 is movable in the space 20b of the base portion 20. That is, the space 20b functions as a conveyance path of the conveyance jig 10. Thus, the one direction in which the grooves 20a extend is the conveying direction of the conveying jig 10. In fig. 1, the conveying direction of the conveying jig 10 is shown by solid arrows.

As shown in fig. 4, the cover portion 22 has through

holes

22a and 22c through which the conveyance object M1 can pass and a through hole 22b through which the conveyance object M2 can pass, at a supply position P described later on the conveyance path as viewed from above. The through

holes

22a, 22b, and 22c are arranged in a direction perpendicular to the conveying direction of the conveying jig 10 when viewed from above. A later-described supply unit 40 for supplying the conveyance objects M1, M2 to the conveyance jig 10 is disposed above the through

holes

22a, 22b, 22c of the cover 22. Thus, when the conveyance jig 10 is positioned at the supply position P on the conveyance path, the conveyance object M1 is supplied from the supply unit 40 to the conveyance jig 10 through the through

holes

22a and 22c of the cover unit 22, and the conveyance object M2 is supplied from the supply unit 40 to the conveyance jig 10 through the through hole 22b of the cover unit 22. In fig. 4, the directions of the objects M1 and M2 supplied from the supply unit 40 to the conveyance jig 10 are shown by solid arrows.

As shown in fig. 2 and 3, the conveyance jig 10 is a flat plate-like member extending in one direction. The conveyance jig 10 pushes the conveyed articles M1, M2 to convey them in the conveyance direction. The conveyance jig 10 includes a holding portion 11, a connecting portion 12, and an arm portion 13. The arm portion 13 has a flat plate shape extending in the one direction. The holding portion 11 is located at one end portion in the one direction with respect to the arm portion 13. The connecting portion 12 is located at the other end portion in the one direction with respect to the arm portion 13. The holding portion 11 includes a plurality of holding

holes

11a, 11b, and 11c for holding the objects M1 and M2. The connection portion 12 is connected to a jig driving portion 80 described later. The detailed structure of the jig for conveyance 10 will be described later.

As shown in fig. 1 and 4, the supply unit 40 is located above the base unit 20 and above the conveyance paths of the conveyed articles M1 and M2. The supply unit 40 has a supply port at a lower end thereof for supplying the objects M1 and M2 to the conveyance jig 10 moving on the conveyance path. That is, the conveyance objects M1 and M2 are supplied from above to the conveyance jig 10 moving on the conveyance path. Accordingly, the supply position P of the object M is below the supply port of the supply unit 40 and on the conveyance path.

The supply unit 40 includes a housing unit 41 and an ejection device 45.

The housing 41 is a columnar member extending in the vertical direction. The housing portion 41 has a plurality of

housing recesses

42, 43, and 44 extending in the vertical direction. The conveyance object M1 is stored in the storage recesses 42 and 44 in a vertically stacked state. The conveyance object M2 is stored in the storage recess 43 in a vertically stacked state.

The plurality of

housing recesses

42, 43, and 44 extend from the lower end to the upper end of the housing 41. Thus, the housing 41 has

upper openings

42a, 43a, 44a in which the

housing recesses

42, 43, 44 are open at the upper end portions, and

lower openings

42b, 43b, 44b in which the

housing recesses

42, 43, 44 are open at the lower end portions. The

upper openings

42a and 44a function as insertion ports for the objects M1 to be transported into the storage recesses 42 and 44. The upper opening 43a functions as an insertion port for the conveyance object M2 into the storage recess 43. The

lower openings

42b and 44b function as supply ports for supplying the conveyed material M1 to the supply position P. The lower opening 43b functions as a supply port for supplying the conveyance object M2 to the supply position P.

As described above, the conveyance table 21 made of a magnetic material is located on the opposite side of the storage section 41 with respect to the supply position P. That is, the conveyor 1 has a magnetic member made of a magnetic material on the side opposite to the supply portion 40 across the supply position P. Thus, in the case of the present embodiment in which the objects M1 and M2 stored in the storage unit 41 are magnets, the objects M1 and M2 are attracted to the magnetic member by magnetic force. This allows the conveyances M1 and M2 stored in the storage 41 in a vertically stacked state to be sucked downward. This allows the position of the lower end of the conveyed object M1 stacked in the vertical direction in the storage recesses 42 and 44 and the position of the lower end of the conveyed object M2 stacked in the vertical direction in the storage recess 43 to be the same. Further, with the above configuration, the conveyances M1 and M2 can be supplied to the supply position P more easily.

The pushing device 45 is located above the storage unit 41. The pushing device 45 pushes the conveyed object M1 located in the storage recesses 42 and 44 downward, and pushes the conveyed object M2 located in the storage recess 43 downward. Specifically, the pushing device 45 includes pushing

units

46 and 48 for pushing the conveyance object M1 downward in the storage recesses 42 and 44, and a pushing unit 47 for pushing the conveyance object M2 downward in the storage recess 43. The pushing

portions

46, 47, and 48 may have a structure including an actuator capable of driving control, such as an air cylinder or a piezoelectric element, or may have a structure in which a spring or the like constantly generates an urging force.

The conveyed articles M1 stacked in the vertical direction in the plurality of storage recesses 42 and 44 of the storage section 41 are pushed downward by the pushing

sections

46 and 48. The conveyance objects M2 stacked in the vertical direction in the plurality of storage recesses 43 of the storage unit 41 are pushed downward by the push-out unit 47.

That is, the supply unit 40 includes: a storage unit 41 for storing the objects M1 and M2 in a stacked state; pushing

units

46 and 48 for pushing the articles M1 stored in the storage unit 41 in a stacked state to one side in the stacking direction; and a pushing unit 47 for pushing the conveyance object M2 stored in the storage unit 41 in a stacked state to one side in the stacking direction. The supply position P is located on one side of the storage unit 41 in the stacking direction of the objects M1 and M2.

This makes it possible to supply the conveyed object M1 stored in the storage recesses 42 and 44 and the conveyed object M2 stored in the storage recess 43 to the supply position P, respectively. Further, with the above-described configuration of the pushing device 45, even when the height of the objects M1 and M2 stacked in the storage recesses differs due to the vertical dimension error of the objects M1 and M2, the positions of the lower ends of the objects M1 and M2 stacked in the storage recesses can be made the same. This prevents a large force from being applied to the conveyance jig 10 due to a positional deviation in the vertical direction of the conveyance objects M1 and M2 when the conveyance objects M1 and M2 are conveyed by using the conveyance jig 10 after the conveyance objects M1 and M2 are supplied to the conveyance jig 10 at the supply position P. Therefore, the jig for conveyance 10 can be more reliably prevented from being damaged.

The position sensor 50 is a sensor for detecting that the conveying jig 10 has reached the supply position P on the conveying path. When the conveying jig 10 reaches the supply position P on the conveying path, the position sensor 50 outputs a detection signal to a control unit 70 described later. The position sensor 50 may have any configuration as long as it can detect the conveying jig 10 at the supply position P on the conveying path. The position sensor 50 may be located near the supply position P of the base portion 20, or may be attached to a position where the position of the conveying jig 10 can be detected in a jig driving portion 80 described later.

The jig driving section 80 moves the conveying jig 10 in the conveying direction in the space 20b of the base section 20. The jig driving unit 80 is, for example, an air cylinder that expands and contracts by air pressure. In the present embodiment, as shown in fig. 1, the jig driving section 80 includes a cylindrical section 81 and a shaft section 82 movable in the cylindrical axis direction in the cylindrical section 81.

The cylinder 81 is fixed to the conveyance table 21 of the base portion 20. The cylindrical axis direction of the cylindrical portion 81 coincides with the conveying direction of the conveying jig 10. The shaft 82 is connected to the connecting portion 12 of the conveyance jig 10. The conveying jig 10 is connected to the shaft portion 82 in a direction extending along the axis. The shaft 82 of the jig driving portion 80 moves in the cylinder direction, and the conveyance jig 10 connected to the shaft 82 moves in the cylinder direction. Thus, the conveying jig 10 can be moved in the conveying direction by the jig driving section 80.

The control unit 70 controls the driving of the jig driving unit 80 using the detection signal output from the position sensor 50, and reciprocates the conveying jig 10 on the conveying path. The control unit 70 drives the jig driving unit 80 to a position where the detection signal is output from the position sensor 50, and positions the conveying jig 10 at the supply position P on the conveying path. The control unit 70 drives the jig driving unit 80 to transport the transport jig 10 holding the objects M1 and M2 by the holding unit 11 to the transport destination on the downstream side in the transport direction from the supply position P. Then, the control unit 70 drives the jig driving unit 80 to the position where the detection signal is output from the position sensor 50, and positions the conveying jig 10 at the supply position P again.

According to the above, the transport apparatus 1 of the present embodiment includes: a conveying jig 10; a jig driving section 80 for moving the conveyance jig 10 to the supply position P of the conveyed objects M1 and M2 and moving the conveyance jig from the supply position P to the downstream side in the conveyance direction; and a supply unit 40 for supplying the objects M1 and M2 to the conveyance jig 10 at the supply position P. According to the conveyor 1 having such a configuration, the objects M1 and M2 supplied from the supply portion 40 at the supply position P can be conveyed downstream in the conveying direction by using the conveying jig 10.

(jig for conveyance)

Next, the structure of the conveyance jig 10 will be described in detail with reference to fig. 2 and 3.

As described above, the conveyance jig 10 is a rectangular flat plate member extending in one direction, and includes the holding portion 11, the connecting portion 12, and the arm portion 13. In the following description, the one direction is referred to as a longitudinal direction of the conveying jig 10. A direction perpendicular to the one direction when the transport jig 10 is viewed from above is referred to as a short-side direction. The longitudinal direction is the same direction as the conveying direction.

The holding portion 11, the connecting portion 12, and the arm portion 13 are one member. At least one of the holding portion 11, the connecting portion 12, and the arm portion 13 may be formed of another member and may be connected to the other member.

The holding portion 11 includes holding

holes

11a and 11c for holding the conveyed object M1 and a holding hole 11b for holding the conveyed object M2. The holding holes 11a and 11c are rectangular holes that are long in the longitudinal direction of the conveyance jig 10 when viewed from above and can accommodate the conveyed object M1. The holding hole 11b is a rectangular hole that is long in the longitudinal direction of the conveyance jig 10 when viewed from above and can accommodate the conveyed object M2. The conveyed article M1 is conveyed in the conveying direction while being held in the holding

holes

11a and 11 c. The conveyed object M2 is conveyed in the conveying direction while being held in the holding hole 11 b.

Specifically, the holding portion 11 includes a plurality of

guide portions

15a, 15b, 15c, and 15d and

coupling portions

16a and 16 b.

The

guide portions

15a, 15b, 15c, and 15d are flat plates parallel to each other and extending in the longitudinal direction. That is, the

guide portions

15a, 15b, 15c, and 15d extend in the conveying direction and are arranged at predetermined intervals in a direction perpendicular to the conveying direction.

In the longitudinal direction, the lengths of the plurality of

guide portions

15a, 15b, 15c, and 15d are the same as the longitudinal lengths of the conveyances M1 and M2 when the conveyances M1 and M2 are viewed from above. The length of the plurality of

guides

15a, 15b, 15c, and 15d in the conveying direction is greater than half the length of the conveyed objects M1 and M2 in the conveying direction.

The length in the conveying direction of an adjacent pair of the plurality of

guide portions

15a, 15b, 15c, 15d is longer than the interval in the direction perpendicular to the conveying direction of an adjacent pair of the plurality of

guide portions

15a, 15b, 15c, 15 d.

In the present embodiment, when the holding portion 11 is viewed from above, the interval between the guide portion 15b and the guide portion 15c is larger than the interval between the guide portion 15a and the guide portion 15b and the interval between the guide portion 15c and the guide portion 15 d.

The

coupling portions

16a and 16b include a 1 st coupling portion 16a that couples one end sides of the plurality of

guide portions

15a, 15b, 15c, and 15d in the longitudinal direction and a 2 nd coupling portion 16b that couples the other end sides of the plurality of

guide portions

15a, 15b, 15c, and 15 d. The 1 st coupling portion 16a couples the upstream ends of the plurality of

guide portions

15a, 15b, 15c, and 15d in the conveying direction. The 2 nd connecting portion 16b connects the ends of the plurality of

guide portions

15a, 15b, 15c, and 15d on the downstream side in the conveying direction. This structure forms the holding

holes

11a, 11b, and 11c surrounded by the

guide portions

15a, 15b, 15c, and 15d, the 1 st coupling portion 16a, and the 2 nd coupling portion 16 b. That is, the objects M1, M2 are held by a pair of adjacent guide portions among the plurality of

guide portions

15a, 15b, 15c, 15d and the 1 st coupling portion 16a and the 2 nd coupling portion 16 b.

The holding unit 11 may have only the 1 st connecting unit 16a necessary for conveying the objects M1 and M2 by pushing them in the conveying direction. That is, the holding portion 11 may not have the 2 nd connecting portion 16 b. In this case, the holding unit 11 has three or more guide portions as the plurality of

guide portions

15a, 15b, 15c, and 15d, and the plurality of objects to be transported M1 and M2 are held in a state of being aligned in a direction perpendicular to the transport direction by a pair of adjacent guide portions among the three or more guide portions and the 1 st coupling portion 16 a. Thus, the plurality of objects M1, M2 can be conveyed in the conveying direction by using the conveying jig 10.

As in the present embodiment, the plurality of

guide portions

15a, 15b, 15c, and 15d are connected by the 2 nd connecting portion 16b at the end portions on the downstream side in the conveying direction of the plurality of

guide portions

15a, 15b, 15c, and 15d, and the conveyed objects M1 and M2 are held by the 1 st connecting portion 16a and the 2 nd connecting portion 16b, which are adjacent pairs of the plurality of

guide portions

15a, 15b, 15c, and 15d, whereby the following operational effects are obtained.

The

guide portions

15a, 15b, 15c, and 15d extending in the conveying direction are connected by a 1 st connecting portion 16a at an upstream end in the conveying direction, and are connected by a 2 nd connecting portion 16b at a downstream end in the conveying direction. This can improve the strength of the holding portion 11. Therefore, the durability of the conveyance jig 10 can be further improved. Further, according to the above configuration, since the objects M1 and M2 can be held by the pair of adjacent guides among the plurality of

guides

15a, 15b, 15c, and 15d, the 1 st coupling portion 16a, and the 2 nd coupling portion 16b, the objects M1 and M2 can be held more reliably by the holding portion 11.

In the present embodiment, when the holding portion 11 is viewed from above, the size of the holding hole 11b is larger than the sizes of the holding

holes

11a and 11c in the above-described short-side direction. This allows the conveyance object M2 having a larger dimension in the width direction than the conveyance object M1 to be held in the holding hole 11 b.

The connecting portion 12 has two mounting

holes

12a, 12b arranged in the longitudinal direction when viewed from above. Bolts, not shown, that pass through the tip end portions of the shaft portions 82 of the jig driving portion 80 pass through the mounting

holes

12a, 12 b. By fixing the bolt with a nut or the like, the connection portion 12 and the shaft portion 82 of the jig driving portion 80 can be connected.

The holding portion 11, the connecting portion 12, and the arm portion 13 have the same dimension in the short side direction.

In a state where the conveyance object M1 is held in the holding

holes

11a and 11c of the conveyance jig 10 having the above-described configuration and the conveyance object M2 is held in the holding hole 11b, the conveyance jig 10 is moved in the conveyance direction by the jig driving unit 80, and the 2 nd connecting portion 16b of the conveyance jig 10 receives a force in the longitudinal direction from the conveyance objects M1 and M2. The force in the longitudinal direction received by the 2 nd coupling portion 16b is transmitted to the arm portion 13.

In the present embodiment, as described above, the objects M1 and M2 are magnets. The articles M1 and M2 are stacked in the vertical direction in the supply unit 40. Therefore, when the conveyance jigs 10 are used to convey the conveyers M1 and M2, the magnetic force generated by the conveyers M1 and M2 increases the force in the longitudinal direction received by the 2 nd connecting part 16 b. That is, the objects M1 and M2 are stacked in the vertical direction in the supply unit 40, and generate an attractive force due to a magnetic force therebetween. Therefore, when the conveyance jig 10 is used to convey the lowermost conveyance objects M1 and M2 of the conveyance objects M1 and M2 stacked in the vertical direction, not only the weight and frictional force of the conveyance objects M1 and M2, but also the force generated by the magnetic force acts on the 2 nd connecting portion 16b of the conveyance jig 10.

As described above, the dimension of the arm portion 13 in the short side direction is the same as the dimension of the holding portion 11 in the short side direction. Therefore, the area of the arm portion 13 of the transport jig 10 receiving the force in the longitudinal direction is larger than the area of the tools receiving the force from the objects M1 and M2 when the objects M1 and M2 are pushed by using the tools having the same size as the size of the objects M1 and M2 in the short side direction. Thus, the jig 10 for conveyance is less likely to be deformed than the above-described jig.

Therefore, the conveying jig 10 having higher durability can be obtained. This can reduce the frequency of maintenance of the conveyance jig 10.

In particular, when the objects M1 and M2 are magnets as described above, if a magnetic force is generated to attract the objects to be transported, a larger force is applied to the transporting jig 10 when the objects to be transported M1 and M2 are transported by using the transporting jig 10. Thus, when the objects M1 and M2 are magnets, the conveyance jig 10 having the above-described configuration is used to convey the objects M1 and M2, thereby preventing the deformation of the conveyance jig 10.

As described above, in the present embodiment, the conveyance jig 10 that conveys the objects M1 and M2 by pushing them in the conveyance direction includes the holding portion 11 that holds the objects M1 and M2. The holding portion 11 has: a plurality of

guide portions

15a, 15b, 15c, 15d extending in the conveying direction and arranged at predetermined intervals in a direction perpendicular to the conveying direction; and a 1 st coupling portion 16a that couples the plurality of

guide portions

15a, 15b, 15c, 15d at least at the upstream end portions of the plurality of

guide portions

15a, 15b, 15c, 15d in the conveying direction, and that holds the conveyed objects M1, M2 by a pair of adjacent guide portions among the 1 st coupling portion 16a and the plurality of

guide portions

15a, 15b, 15c, 15 d.

In the above configuration, the plurality of

guide portions

15a, 15b, 15c, and 15d arranged at predetermined intervals in the direction perpendicular to the conveyance direction of the conveyed objects M1 and M2 are connected by the 1 st connecting portion 16 a. The objects M1 and M2 are conveyed while being held by the 1 st coupling portion 16a and a pair of adjacent guide portions among the plurality of

guide portions

15a, 15b, 15c, and 15 d. Therefore, when the objects M1 and M2 are conveyed, a force is applied to the 1 st coupling part 16 a. As described above, the area of the first coupling portion 16a to which the force is applied is larger than the area of the jigs to which the forces are applied from the objects M1 and M2 when the objects M1 and M2 are pushed by using jigs having the same size as the size of the objects M1 and M2 in the short side direction, respectively. Therefore, the jig 10 for conveyance is less likely to be deformed. This can improve the durability of the conveyance jig 10, and thus can reduce the frequency of maintenance of the conveyance jig 10.

In the present embodiment, the lengths of the plurality of

guide portions

15a, 15b, 15c, and 15d in the conveying direction are greater than one-half of the lengths of the conveyed objects M1 and M2 in the conveying direction. This prevents the conveyance objects M1 and M2 from moving in a direction perpendicular to the conveyance direction when the conveyance objects M1 and M2 are held by the holding portion 11. Therefore, the objects M1, M2 can be held more reliably by the plurality of

guide portions

15a, 15b, 15c, 15 d.

Further, the length in the conveying direction of the adjacent pair of the plurality of

guide portions

15a, 15b, 15c, and 15d is larger than the interval in the direction perpendicular to the conveying direction of the adjacent pair of the plurality of

guide portions

15a, 15b, 15c, and 15 d.

Thus, the conveyance objects M1 and M2 having a length in the conveyance direction larger than a length in a direction perpendicular to the conveyance direction can be conveyed by using the conveyance jig 10. When the objects M1 and M2 are magnets, a larger force is applied to the conveyance jig 10 by the magnetic force of the magnets when the conveyance jig 10 is used to convey the objects M1 and M2 having the above-described shapes. In contrast, by using the conveyance jig 10 having the above-described configuration to convey the objects M1 and M2, the conveyance jig 10 can be prevented from being deformed.

(operation of the conveyor)

Next, an operation of conveying the objects M1 and M2 by the conveyor 1 will be described with reference to fig. 1, 3, and 4.

First, the control unit 70 controls the driving of the jig driving unit 80 using the detection signal output from the position sensor 50, thereby moving the conveying jig 10 in the conveying direction and positioning the conveying jig at the supply position P below the supply unit 40. At this time, the holding

hole portions

11a, 11b, and 11c of the holding portion 11 of the conveying jig 10 are positioned below the

lower openings

42b, 43b, and 44b, respectively, which are the supply ports of the supply portion 40. This state is the state shown in fig. 1.

In the supply section 40, the objects M1 stacked in the vertical direction in the storage recesses 42 and 44 of the storage section 41 are pushed downward by the push-out

sections

46 and 48 of the push-out device 45. Thus, the conveyed articles M1 are supplied from the

lower openings

42b, 44b of the storage section 41 to the holding

holes

11a, 11c of the conveying jig 10 located at the supply position P. The supplied article M1 is held in the holding

holes

11a and 11c of the conveyance jig 10.

Similarly, in the supply unit 40, the objects M2 stacked in the vertical direction in the storage recess 43 of the storage unit 41 are pushed downward by the push unit 47 of the push device 45. Thus, the conveyed object M2 is supplied from the lower opening 43b of the storage portion 41 to the holding hole 11b of the conveying jig 10 located at the supply position P. The supplied article M1 is held in the holding hole 11b of the conveyance jig 10. Fig. 4 shows a case where the objects M1 and M2 are supplied from the supply unit 40 to the conveyance jig 10.

Then, the control unit 70 drives and controls the jig driving unit 80 to move the conveyance jig 10 to the downstream side in the conveyance direction as shown in fig. 3, thereby conveying the objects M1 and M2 to the conveyance destination. In fig. 3, the conveying direction of the conveying jig 10 is shown by solid arrows.

Although not shown in the drawings, after the objects M1 and M2 are transported to the destination using the transporting jig 10, the objects M1 and M2 are separated from the transporting jig 10 at the destination. Then, the control unit 70 controls the driving of the jig driving unit 80 using the detection signal output from the position sensor 50, thereby moving the conveying jig 10 to the upstream side in the conveying direction and positioning the conveying jig at the supply position P.

By repeating the above operation, the conveying device 1 conveys the objects M1 and M2 stored in the supply unit 40 to the conveying destination by the conveying jig 10.
