The first side portion 48 and the second side portion obliquely extending from one end of the first side portion 48. It has a portion 49 and a third side portion 50 that extends obliquely from the other end of the first side portion 48 and that has a different linear shape or inclination angle from the second side portion 49. The first side portion 48 may be located parallel to the main transport direction F or may be diagonal to the main transport direction F. In any case, the first side portion 48 It suffices that one end of the portion 48 is located in the main transport direction F and the other end of the first side portion 48 is located on the side opposite to the main transport direction F. The second side portion 49 extends in an arc shape from one end of the first side portion 48 toward the first edge portion 46, and the third side portion 50 extends from the other end of the first side portion 48 to the first edge. It extends in a straight line inclined toward the direction of the portion 46.

As shown in FIG. 4, the connector 27 includes a connector 37a for the left side mounted on the left end of the roller 37 in the longitudinal direction and a connector for the right side mounted on the right end of the roller 37 in the longitudinal direction. 27b, and the left-side connecting body 27a and the right-side connecting body 27b are provided in left-right different shapes. Therefore, the first insertion hole 45a and the second side portion 49 are located on the downstream side in the main transport direction F and the upstream side in the main transport direction F of the connecting bodies 27 mounted on the left and right ends of the roller 37. The second insertion hole 45b and the third side portion 50 are located.

The head portion 42 has a direction display portion 51 that allows the left-right direction of the roller 37 to be visually recognized when the body portion 41 is attached to the opening portion 38 of the roller 37. The direction display section 51 is displayed on the outer side surface of the head 42 and in the first head area 43, and is constituted by an arrow indicating the main transport direction F.

The plurality of pins 34 extend in a direction intersecting the main transport direction F, one end side is held by the endless rotating body 25, the other end side is held by the connecting body 27, and a plurality of pins 34 are arranged along the longitudinal direction of the chain 31. ing. Each connecting body 27 holds a part and two or more of the pins 34 which are the connecting bodies 28, and holds two pins 34 in the present embodiment.

In addition, the moving body 29 is a slat 54 that carries and conveys an object to be conveyed. The slat 54 has a slat main body 55 which is long in the longitudinal direction of the roller 37 and is disposed between two adjacent rollers 37 and has a substantially I-shaped cross section. On both sides of the slat body 55 intersecting with the longitudinal direction, fitting portions 56 that are slidably fitted on the outer peripheral surface of the roller 37 along the longitudinal direction are provided. The fitting portions 56 are provided at both ends in the longitudinal direction of the slat body 55 and at a plurality of positions between these both ends. A mounting surface 57 for mounting an object to be conveyed is formed on the upper surface of the slat body 55, and a moving pin 58 is projected on the lower surface of the slat body 55.

Further, as shown in FIGS. 9 to 11, the distribution unit 14 is arranged on the frame 12 between the upper rotation region and the lower rotation region of the carrier 13. The distribution unit 14 distributes the slats 54 in the longitudinal direction of the rollers 37 via the moving pins 58 of the slats 54 of the rotating carrier 13. The distribution unit 14 includes a guide mechanism 61 that guides the moving direction of the moving pin 58 of the slat 54 that moves with the rotation of the transport body 13. The guide mechanism 61 includes a first route R1 that guides the slat 54 in a straight direction along the main transport direction F, a second route R2 that guides the slat 54 to the right from the first route R1, and a first route R1. It has a third route R3 for guiding the slat 54 to the left. At each branch position of the first route R1, the second route R2, and the third route R3, a switching mechanism that switches the route along which the moving pin 58 moves is arranged.

Next, the operation of the carrier device 10 will be described.

In the transporting device 10, as the transport body 13 rotates in the main transport direction F, the slat 54 wraps around from the lower rotation region of the transport body 13 to the upper rotation region on the upstream side in the main transport direction F. .. At this time, the guide mechanism 61 of the sorting unit 14 guides the slat 54 so as to be positioned at the center of the roller 37 in the longitudinal direction.

The articles conveyed from the conveyor on the upstream side of the conveyor 10 are received on the plurality of slats 54 and conveyed in the main conveyance direction F. At this time, the sensor S detects the tip position, length, etc. of the conveyed product, and identifies the plurality of slats 54 on which the conveyed product is placed.

In the case of distributing to the first route R1 based on the distribution information, the plurality of slats 54 on which the conveyed objects are placed are moved straight along the first route R1 by the distribution unit 14, and the downstream side in the main conveying direction F. Send from the center position in the width direction of. Further, in the case of distributing the conveyed product to the second route R2, the distribution unit 14 branches the plurality of slats 54 carrying the conveyed product from the first route R1 to the second route R2, and the right side of the roller 37 (see FIG. 9) and the plurality of slats 54 to move the conveyed object toward the widthwise right side position (upper side position in FIG. 9) on the downstream side in the main conveying direction F. Further, in the case of distributing the conveyed product to the third route R3, the plurality of slats 54 on which the conveyed product is placed are branched by the distribution unit 14 from the first route R1 to the third route R3, and the left side of the roller 37 (Fig. 9 lower side), the conveyed object is moved together with the plurality of slats 54, and is fed from the left side position in the width direction on the downstream side in the main conveying direction F (lower side position in FIG. 9).

Among the slats 54 that have moved from the upper rotation region of the transport body 13 to the lower rotation region on the upstream side in the main transport direction F, the slats 54 that have moved to the right or left side of the roller 37 are moved by the distribution unit 14 to the rollers. It is returned to the center of 37 and goes around to the upper rotation area of the carrier 13.

Further, during the carrying operation of the carrying device 10, the two pins 34 of the chain 31 are inserted into the connecting body 27 of the rollers 37, and the rollers 37 are supported by these two pins 34, so that the rollers 37 are rotated. The roller 37 does not rotate even if force is applied.

When a part of the conveyed product is placed on the roller 37 and the conveyed product moves to the right side or the left side of the roller 37 together with the slat 54, the conveyed product reaches the position of the head 42 of the coupling body 27 at the end of the roller 37. However, since the first edge portion 46 of the head portion 42 of the connecting body 27 is equal to or smaller than the outer circumference of the roller 37, the conveyed object does not get caught on the head portion 42 of the connecting body 27 and is conveyed. It becomes possible to smoothly convey the object.

If the amount of movement of the slat 54 that moves toward the end of the roller 37 becomes excessive, the slat 54 contacts the chain 31, causing oil stains on the slat 54, or pressing the chain 31 with the slat 54 to guide the chain 31. Although there is a possibility that it will come off from the rail 20, since the second edge portion 47 of the head portion 42 of the connecting body 27 is located outside the outer periphery of the roller 37, the slat 54 abuts on the head portion 42 of the connecting body 27. The restricted movement prevents the slats 54 from contacting the chain 31.

Further, since the chain 31 expands as it is used, if the two pins 34 of the chain 31 are inserted into the connecting body 27, the connecting body 27 may be damaged due to failure to cope with the extension of the chain 31, or The pitch of the plurality of rollers 37 may vary, and the movement of the slats 54 may be affected. The connecting body 27 into which the two pins 34 of the chain 31 are inserted has a first insertion hole 45a formed in a round hole shape according to the diameter of the pin 34, and a main transport direction F more than the first insertion hole 45a. Since it has the second insertion hole 45b formed in a long long hole, the roller 37 is positioned with respect to the chain 31 with the first insertion hole 45a as a reference, so that a plurality of rollers in the main transport direction F can be obtained. While the pitch of the rollers 37 is kept constant, the elongation of the chain 31 is absorbed by the second insertion holes 45b.

In addition, the first insertion hole 45a is located on the downstream side in the main transport direction F and the second insertion hole 45b is located on the upstream side in the main transport direction F with the connecting bodies 27 mounted on both ends of the roller 37. By virtue of the left-right misalignment, the pitch of the plurality of rollers 37 in the main transport direction F can be maintained at a constant dimension even if the chain 31 extends.

Further, the roller 37, to which the connecting body 27 having the directivity of the first insertion hole 45a and the second insertion hole 45b with respect to the main transport direction F is attached at both ends, is the roller 37 when the transport body 13 is assembled. It is necessary to assemble them so that the left and right assembly directions are correct.

Since the connecting body 27 is formed in a left-right different shape on the left side and the right side of the roller 37, by checking the connecting body 27, the left and right assembly directions of the roller 37 can be grasped, and the left and right sides of the roller 37 can be grasped. It is possible to assemble without making a mistake in the assembly direction.

That is, since the direction display portion 51 that allows the left-right direction of the roller 37 to be visually recognized is displayed on the connecting body 27, the left-right assembly direction of the roller 37 can be easily grasped.

Further, the outer periphery of the head 42 of the coupling body 27 includes a first side portion 48 located along the main transport direction F and a second side portion 49 extending obliquely from one end of the first side portion 48. , The third side portion 50 having a linear shape or a different inclination angle and extending obliquely from the other end of the first side portion 48, the shape of the head portion 42 of the coupling body 27 causes the roller 37. It is possible to easily grasp the left and right assembling directions. When assembling the connecting body 27 to the roller 37, set only one of the left and right connecting bodies 27 in a fixed posture so that the connecting body 27 is not attached to the left and right openings 38 of the roller 37 in different directions. The left and right mounting jigs can be manufactured, and the occurrence of assembly errors can be prevented.

In the transporting device 10 of the present embodiment configured as described above, since the connecting body 27 mounted on the roller 37 holds two or more pins 34 of the chain 31, the roller 37 is prevented from rotating and the pin It is possible to prevent the wear between the 34 and the coupling body 27 and the wear between the roller 37 and the slat 54. Moreover, since the rollers 37 are supported on the chain 31 by the plurality of pins 34, the strength can be improved.

Further, since the connector 27 can hold two or more pins 34 inside the opening 38 of the roller 37, the two or more pins 34 can be used to support the roller 37.

In addition, the insertion hole 45 of the connecting body 27 includes a first insertion hole 45a formed in a round hole shape according to the diameter of the pin 34, and a long hole longer in the main transport direction F than the first insertion hole 45a. Since it has the second insertion hole 45b formed in a shape, by positioning the roller 37 with respect to the first insertion hole 45a with respect to the chain 31, the pitch of the plurality of rollers 37 in the main transport direction F can be adjusted. The extension of the chain 31 can be absorbed by the second insertion hole 45b while maintaining a constant size.

Further, since the head portion 42 of the connected body 27 has the first edge portion 46 which is equal to or smaller than the outer circumference of the roller 37, when the conveyed object is moved to the end side of the roller 37, the conveyed object is conveyed. It is possible to get over the head 42 without getting caught on the head 42, and it is possible to smoothly convey the conveyed object.

Furthermore, since the head portion 42 of the connecting body 27 has the second edge portion 47 located outside the outer circumference of the roller 37, the movement position of the slat 54 that moves toward the end portion of the roller 37 can be limited, It is possible to prevent the slat 54 from coming into contact with the chain 31 and causing oil stains, and the slat 54 from pushing the chain 31 to disengage the chain 31 from the guide rail 20.

Further, since the connecting body 27 is formed in a left-right-handed shape on the left side and the right side of the roller 37, it is possible to make the assembly direction of the roller 37 correspond to the main transport direction F when the transport body 13 is assembled. it can.

Further, since the head portion 42 of the connecting body 27 has the direction display portion 51 for visually recognizing the left-right direction of the roller 37 in the state where the body portion 41 is attached to the opening portion 38 of the roller 37, the assembly of the transport body 13 is performed. At this time, the assembling direction of the roller 37 can be easily grasped, the assembling workability can be improved, and an error in the assembling direction of the roller 37 can be prevented.

Further, the outer periphery of the head portion 42 of the connector 27 has a first side portion 48 having one end located in the main transport direction F and the other end located on the side opposite to the main transport direction F, and the first side portion 48. A second side portion 49 that extends obliquely from one end and a third side portion 50 that extends obliquely from the other end of the first side portion 48 and has a different linear shape or inclination angle from the second side portion 49. Therefore, when the transport body 13 is assembled, the assembly direction of the roller 37 can be easily grasped from the shape of the head 42 of the connection body 27, and the assembly direction of the roller 37 can be prevented from being incorrect.

Further, since the second side portion 49 and the third side portion 50 are located outside the outer circumference of the roller 37, the shape of the head 42 of the connecting body 27 can be easily grasped. In addition, the second side portion 49 and the third side portion 50 can limit the movement position of the slat 54 that moves to the end side of the roller 37, and the slat 54 contacts the chain 31 to prevent oil stains. It is possible to prevent the chain 31 from being dislodged or being pushed by the slats 54 to push the chain 31 out of the guide rail 20.

Next, a second embodiment will be described with reference to FIGS.

In the second embodiment, as the connecting body 28, a plurality of pins 70 dedicated to connection, which are different from the pins 34 that connect the pair of outer plates 32 and the pair of inner plates 33 of the chain 31, are used. That is, the pin 70 that is the connecting body 28 extends in the direction intersecting the main transport direction F, one end side is held by the chain 31 that is the endless rotating body 25, and the other end side is held by the connecting body 27.

Further, the chain 31 includes a bracket 71 for supporting the roller 37. The bracket 71 is one of the pair of outer plates 32 and is integrally provided on the outer plate 32 located inside the main transport path 11. The bracket 71 is projected to the outer peripheral side of the chain 31 and holds one end side of two or one pin 70 at the tip end side in the projecting direction. The bracket 71 may be provided integrally with the outer plate 32 located outside the main transport path 11. Alternatively, the bracket 71 may be provided separately from the outer plate 32, and the bracket 71 may be attached to the outer plate 32 by overlapping with the plurality of pins 34. In this case, the bracket 71 corresponds to both the case where it is attached to one outer plate 32 and the case where it is attached across two outer plates 32.

The pin 70 is previously integrated with the chain 31 side as shown in FIGS. 12 to 14, and is previously integrated with the coupling body 27 of the roller 37 as shown in FIGS. 15 to 17. There are cases.

The insertion hole 72 is a first insertion hole 72a formed in a round hole shape according to the diameter of the pin 70, and the insertion hole 72 located on the opposite side to the main transport direction F is more than the first insertion hole 72a. The second insertion hole 72b is formed in a long hole shape that is long in the main transport direction F. In this case, since the two pins 70 projecting from the one connecting body 27 are attached to the one bracket 71, the elongation of the chain 31 does not affect the two inserting holes 72 and the first inserting hole 72a. Alternatively, the bracket 71 common to the case where the two pins 70 projecting from one connecting body 27 are inserted into the respective insertion holes 72 of the adjacent brackets 71 may be used.

When the two pins 70 projecting from one connecting body 27 are inserted into the insertion holes 72 of each one of the adjacent brackets 71, the insertion holes 72 of each bracket 71 are located on the main transport direction F side. The insertion hole 72 is a second insertion hole 72b having a long hole shape, and the insertion hole 72 located on the side opposite to the main transport direction F is a first insertion hole 72a having a round hole shape. In this case, the first insertion hole 72a of the one bracket 71 located on the side of the main transport direction F holds one pin 70 of the connecting body 27 and holds it, and the other bracket located on the side opposite to the main transport direction F is inserted. The second insertion hole 72b of 71 holds and inserts the other pin 70 of the connector 27, so that the elongated insertion hole 72b can absorb the extension of the chain 31. It should be noted that when the chain 31 rotates along the outer diameter portion of the sprocket 19, the interval between the adjacent brackets 71 increases, but by increasing the outer diameter of the sprocket 19, the interval between the adjacent brackets 71 increases. It is possible to reduce the distance, and the widening of the gap can be absorbed by the second insertion hole 72b having a long hole shape.
