However, the conventional technology (regulator) can be used without problems when the object to be transported is a lightweight object, but is adopted as it is when the object to be transported is a heavy object ranging from several hundred to several thousand kilograms, for example. There is a problem that you can not.
This is because when the object to be transported is a heavy object, the driving force of the variable member that forcibly moves the object to be transported to the stopper side is increased, and it is damaged when the object to be transported moves on the mounting table. This is because wear powder is generated and the clean state of the surrounding environment is impaired.
Therefore, even if the object to be transported is a heavy object, it is expected to perform the regulation smoothly and efficiently.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to propose a regulation device and a conveyance device that can smoothly and efficiently regulate an object to be conveyed.

In order to solve the above problems, the following means are employed in the regulation device and the transport device according to the present invention.
The setting apparatus according to the present invention includes a transfer unit that places a transfer object and moves the transfer object in a first direction, a moving unit that holds the transfer unit in a second direction that intersects the first direction, And a setting unit that sets the object to be conveyed at a predetermined position in the second direction.

  Moreover, the said setting part has a pair of setting member which clamps the said to-be-conveyed object in said 2nd direction, It is characterized by the above-mentioned.

  The pair of setting members are provided to be movable in the second direction, and are connected to a link mechanism rotatably supported at the predetermined position.

  Moreover, it has a drive source which provides a moving force to either one or both of said pair of setting members.

  In addition, the moving unit includes a contact member that contacts the front side of the transported object and a pressing mechanism that presses the back side.

  The present invention is characterized in that, in a transport apparatus having a main transport path and a sub transport path intersecting with the main transport path, the regulating device is arranged at one end of the sub transport path.

According to the present invention, the following effects can be obtained.
In the calibration apparatus according to the present application, the conveyance unit that conveys the object to be conveyed in the first direction is held by the movement unit so as to be movable in the second direction intersecting the first direction. When the predetermined position in the second direction is set, the transport unit moves in the second direction together with the transported object. For this reason, the driving force of the setting part can be reduced. Further, there is no generation of scratches on the bottom surface or the like of the conveyed object, and further, no abrasion powder is generated during the calibration. Therefore, it is possible to smoothly and efficiently adjust the conveyed object.

The transport device 20 includes a main transport path 1, a sub transport path 4 disposed so as to be substantially orthogonal to the main transport path 1, and a setting unit 11 provided in the sub transport path 4.
The linear main transport path 1 is a roller conveyor configured by arranging a large number of rollers r in parallel at predetermined intervals. The main transport path 1 is configured so that the transported objects W and W ′ can be transported from one side to the other side. In FIG. 1, the articles to be transported W and W ′ can be transported from the left side to the right side of the main transport path 1.
And this main conveyance path 1 is comprised so that it may fully endure to-be-conveyed objects W and W 'whose weight ranges from several hundred to several thousand kilograms.

The transported objects W and W ′ indicate two types of transported objects having different sizes. That is, both of the objects to be conveyed W and W ′ have a rectangular shape whose plan shape is horizontally long. Of these, the object to be conveyed W is a object to be conveyed having a larger planar shape than the object to be conveyed W ′. Is shown.
These conveyed objects W and W ′ are a pallet storing a product to be subjected to predetermined processing / processing at a later-described regulation location, a holder holding the product, or a product itself to be processed. It is configured.
In addition, the planar shape of these conveyed objects W and W ′ is not limited to a horizontally long rectangle as illustrated, and may be a regular octagon, for example.
Hereinafter, the description will be made focusing on the conveyed object W.

A pair of chain conveyors 2 a and 2 b are provided in the middle of the main conveyance path 1. The chain conveyors 2a and 2b are respectively provided between the plurality of rollers r described above. A plurality of (three in the illustrated example) rollers r are interposed between the chain conveyors 2a and 2b. The chain conveyors 2a and 2b are extended in a direction parallel to the direction of the rotation axis of the roller r.
And these chain conveyors 2a and 2b are comprised so that it can move to an up-down (vertical) direction with the up-and-down moving mechanism 3, as FIG. 2 shows.
The chain conveyors 2a, 2b and the vertical movement mechanism 3 are configured to sufficiently withstand the object W to be transported over several hundred to several thousand kilograms, similarly to the main transport path 1 described above.

As shown in FIG. 2A, the vertical movement mechanism 3 is set so that the upper surface position of the chain conveyors 2 a and 2 b is lower than the upper surface position of the roller r in the main conveyance path 1. Therefore, in this state, the main transport path 1 can transport the transported object W regardless of the chain conveyors 2a and 2b.
On the other hand, as shown in FIG. 2B, when the vertical movement mechanism 3 is raised, the upper surface position of the chain conveyors 2a and 2b becomes higher than the upper surface position of the roller r of the main conveyance path 1, and the sub conveyance path 4 is set at the same height as the upper surface position of rollers Ra and Rb (described later).

In the main conveyance path 1 and the chain conveyors 2a and 2b having the above-described configuration, first, the chain conveyors 2a and 2b are lowered, and the main conveyance path 1 conveys the article W to be conveyed onto the chain conveyors 2a and 2b. When this is detected by a sensor (not shown), the conveyance of the main conveyance path 1 is stopped, and then the vertical movement mechanism 3 is raised.
Next, the chain conveyors 2a and 2b and the rollers Ra and Rb are rotationally driven by a driving source (not shown) in the direction of the arrow in FIG. It is sent out to the conveyance path 4 side.
And after the to-be-conveyed object W is sent to the sub conveyance path 4 side, rotation of the chain conveyors 2a and 2b is stopped, and then the chain conveyors 2a and 2b are lowered, and the conveyance operation of the main conveyance path 1 is resumed. .

As will be described later, the object to be conveyed W sent to the sub-conveying path 4 is subjected to position and orientation correction processing by the setting unit 11 and then subjected to predetermined processing and the like.
When the processing or the like is finished, the main transport path 1 is stopped and the vertical movement mechanism 3 is raised, and the chain conveyors 2a and 2b and the rollers Ra and Rb are in the direction indicated by the arrows in FIG. It is driven to rotate in the opposite direction (clockwise in the illustrated example).
As a result, the article W to be transported is sent from the sub transport path 4 to the main transport path 1 side.

When the above-described sensor or the like detects that the conveyed object W sent from the sub-transport path 4 has reached a predetermined position on the main transport path 1, the rotation of the chain conveyors 2a and 2b and the rollers Ra and Rb Is stopped and the vertical movement mechanism 3 is lowered.
Then, the conveyance of the main conveyance path 1 is restarted, and the to-be-conveyed object W is conveyed toward the next process location etc.

As described above, the sub-transport path 4 is provided in the width direction (side) of the main transport path 1 and at a position corresponding to the chain conveyors 2a and 2b. Similar to the main transport path 1 and the pair of chain conveyors 2a and 2b described above, the sub transport path 4 is configured so that a transported object W made of a heavy object can be sufficiently placed thereon.
The sub-transport path 4 has a frame 6 (moving part) that is movably provided on a pair of rails 5 a and 5 b that are provided parallel to the transport direction of the main transport path 1 and at a predetermined interval. doing.
The pair of rails 5a, 5b and the frame 6 are connected using a so-called LM guide (Linear Motion Guide) mechanism. Accordingly, the frame 6 can move with a very small force in the longitudinal direction (second direction) of the rails 5a and 5b, but the direction orthogonal to the longitudinal direction (conveying direction of the sub-conveying path 4: first direction). ) Cannot be moved.
Although not shown, stoppers for receiving the frame 6 are provided at both ends of the rails 5a and 5b so that the frame 6 does not deviate from the rails 5a and 5b.

A plurality of rollers Ra and Rb (conveying units) are provided on each of the left and right sides of the upper surface of the frame 6. That is, the roller Ra is provided at a position corresponding to one of the pair of chain conveyors 2a and 2b. The rotation axis direction is parallel to the longitudinal direction of the rails 5a and 5b and is provided at a predetermined interval.
Similarly, the roller Rb is provided at a position corresponding to the other chain conveyor 2b. The rotation axis direction is parallel to the longitudinal direction of the rails 5a and 5b and is provided at a predetermined interval.
The upper surface positions of the rollers Ra and Rb are provided so as to slightly protrude from the upper surface position of the frame 6.
The rollers Ra and Rb are connected to a motor (not shown) via an endless chain or the like, and are configured to be able to rotate in the same direction at the same time. Moreover, forward rotation and reverse rotation are possible.
In the example shown in the figure, the rollers Ra and Rb are separately provided on the left and right sides of the frame 6. However, rollers having a length reaching both the left and right sides of the frame 6 are provided at predetermined intervals. It may be. Further, the rollers Ra and Rb do not have to be drive rollers that are all driven to rotate, and some of them may be so-called free.

The frame 6 is provided with stoppers 7a and 7b on the end surface opposite to the chain conveyors 2a and 2b. Among these, one stopper 7a is provided at a position facing the roller Ra, and the other stopper 7b is provided at a position facing the roller Rb.
The stoppers 7a and 7b are provided so as to protrude from the upper surface positions of the rollers Ra and Rb, and receive the side surface (front surface side) of the article W to be conveyed conveyed on the rollers Ra and Rb. Can be done.

The frame 6 is provided with pressing pieces 8a and 8b on the chain conveyors 2a and 2b side. Among these, one pressing piece 8a is provided on one roller Ra side so as to face one stopper 7a, and the other pressing piece 8b is provided on the other roller Rb side so as to face the other stopper 7b. ing.
It should be noted that the rollers Ra and Rb arranged at the locations where the pressing pieces 8a and 8b are provided are formed shorter in length than the other rollers Ra and Rb so as not to contact the pressing pieces 8a and 8b. Has been devised.
The pressing pieces 8a and 8b are configured to be driven by hydraulic cylinders 9a and 9b, respectively, as shown in FIGS. 3 (a) and 3 (b). That is, the main body sides of the hydraulic cylinders 9a and 9b are rotatably provided on the frame 6, respectively, and the rod ends of the hydraulic cylinders 9a and 9b rotate to substantially intermediate positions of the arms 10a and 10b having the pressing pieces 8a and 8b, respectively. It is supported freely.
In addition, the front-end | tip part of the arms 10a and 10b which have the press pieces 8a and 8b is each formed with the rotating roller. The hydraulic cylinders 9a and 9b may be air cylinders.

As shown in FIG. 3A, when the rods of the hydraulic cylinders 9a and 9b are retracted, the upper surface positions of the pressing pieces 8a and 8b are set lower than the upper surface positions of the rollers Ra and Rb. Therefore, in this state, the rollers Ra and Rb can move the conveyed object W.
On the other hand, as shown in FIG. 3B, when the rods of the hydraulic cylinders 9a and 9b are protruded, the upper surface positions of the pressing pieces 8a and 8b become higher than the upper surface positions of the rollers Ra and Rb, The back side of the conveyed object W on the rollers Ra and Rb is pressed.

As shown in FIGS. 3A and 4A, the article W to be conveyed is sent from the main conveyance path 1 side to the sub conveyance path 4 via the chain conveyors 2a and 2b. That is, the state shown in FIG.
As shown in FIG. 4A, the transport posture of the transported object W is inclined (rotated) with respect to the transport direction of the sub transport path 4. Therefore, it is necessary to regulate so that the straight side on the front side of the conveyed object W is parallel to the straight line connecting the stoppers 7a and 7b. This attitude is set to the correct attitude of the conveyed object W.

As shown in FIG. 4B, when the conveyance by the rollers Ra and Rb further proceeds, the front side of the conveyed object W comes into contact with both stoppers 7a and 7b. That is, here, the front side of the conveyed object W first comes into contact with the stopper 7a, and if the rotation of the rollers Ra and Rb is further continued in this state, the front side of the conveyed object W comes into contact with the stopper 7b. Then, the posture of the transported object W is set to a predetermined correct posture.
In addition, after the front side of the transported object W comes into contact with the one stopper 7a (or 7b) after the front side of the transported object W comes into contact with the other stopper 7b (or 7a), The amount that the conveyed object W rotates and slides on the rollers Ra and Rb is small. For this reason, there is almost no possibility of generation | occurrence | production of the damage | wound on the bottom face of the to-be-conveyed object W, and generation | occurrence | production of abrasion powder.

Next, as shown in FIGS. 3B and 4C, the article W to be transported is fixed on the sub transport path 4 (frame 6). That is, when the front side of the conveyed object W comes into contact with both the stoppers 7a and 7b, the rotational driving of the rollers Ra and Rb is stopped. Next, the hydraulic cylinders 9a and 9b are driven so that the back side of the conveyed object W is pressed by the pressing pieces 8a and 8b, and the conveyed object W is sandwiched and fixed by the pressing pieces 8a and 8b and the stoppers 7a and 7b. The
In addition, after the article to be conveyed W is fixed on the sub-conveying path 4 (frame 6), the article to be conveyed W is further regulated at a correct position by the regulation unit 11.

Next, the setting part 11 is demonstrated using FIG.1, FIG5 and FIG.6.
5 is a plan view in which the sub-transport path 4 is removed from FIG. 1, and FIG. 6 is a cross-sectional view taken along the line CC in FIG.
The setting part 11 is mainly composed of a first setting member 11a and a second setting member 11b. The first setting member 11a and the second setting member 11b are provided apart from the frame 6 in the left-right direction of the frame 6 (the moving direction of the frame 6: the second direction).
The first setting member 11a and the second setting member 11b are movably provided on the pair of rails 12a and 12b, respectively. Similarly, the pair of rails 12a and 12b and the first and second setting members 11a and 11b are connected to each other using an LM guide mechanism. The rails 5a and 5b and the rails 12a and 12b are laid in parallel.
Therefore, the first setting member 11a and the second setting member 11b can move with a very small force in the longitudinal direction (second direction) of the rails 12a and 12b, but the direction orthogonal to the longitudinal direction (first direction). ) Cannot be moved.

  As shown in FIG. 6, the first regulating member 11 a and the second regulating member 11 b have a U-shape in which the opening sides are opposed to each other when viewed from the side, and the upper ends of the U-shapes are in contact with each other. The contact portions 11c and 11d are formed respectively. The abutting portions 11c and 11d are determined to have heights that can face the conveyed object W placed (fixed) on the frame 6 (rollers Ra and Rb).

Further, the first setting member 11 a and the second setting member 11 b are connected via the link mechanism 13 on the lower side of the frame 6. The link mechanism 13 has a link rod 15 having a central portion rotatably supported on a support shaft 14 fixedly provided between the first setting member 11a and the second setting member 11b. Then, one end of each of the connecting rods 16a and 16b is rotatably connected to both ends of the link rod 15, and the other between the first and second setting members 11a and 16b is connected to the other end of the connecting rods 16a and 16b. It is pivotally connected.
The connecting rods 16a and 16b are formed to have the same length, and the connecting portion between the connecting rod 16a and the first setting member 11a and the connecting portion between the connecting rod 16b and the second setting member 11b are on a straight line passing through the support shaft 14. Is set at an equal distance from the support shaft 14.
Therefore, when the first setting member 11a moves toward the support shaft 14 along the rails 12a and 12b, the second setting member 11b moves toward the support shaft 14 by the same amount as the first setting member 11a. (See the two-dot chain line in FIGS. 5 and 6).
Conversely, when the first setting member 11a is far from the support shaft 14, the second setting member 11b is also moved away from the support shaft 14 by the same amount as the first setting member 11a. (See solid lines in FIGS. 5 and 6).

The first setting member 11a and the second setting member 11b are each driven by a hydraulic cylinder 17a. The hydraulic cylinder 17 a is provided on the first setting member 11 a side and is connected to the second setting member 11 b via the link mechanism 13. Then, the first regulating member 11 a is directly driven by the one hydraulic cylinder 17 a and the second regulating member 11 b is indirectly driven through the link mechanism 13. Thus, the first setting members 11a and 11b are reciprocated along the rails 12a and 12b.
Note that an air cylinder may be used instead of the hydraulic cylinder 17a, and a drive source such as a motor may be employed. Further, the link rod 15 may be rotated by a driving source such as a motor instead of the hydraulic cylinder 17a.

  In addition to the case where the two regulating members 11a and 11b are driven by one hydraulic cylinder 17a, the hydraulic cylinder is also arranged on the second regulating member 11b side and the two regulating members 11a and 11b are driven by the two hydraulic cylinders. May be. In that case, the link mechanism 13 may be provided to move the two regulating members 11a and 11b in conjunction with each other, or the regulating members 11a and 11b may be moved independently without providing the link mechanism 13. .

Next, the operation of the setting unit 11 will be described with reference to FIGS. That is, the conveyed object W (see FIG. 4C) sandwiched between the stoppers 7a and 7b and the pressing pieces 8a and 8b and fixed on the frame 6 (rollers Ra and Rb) is regulated to a predetermined correct position. The operation will be described.
In these drawings, a point O indicates a normal position (predetermined correct position: predetermined position) of the conveyed object W, and a point X indicates a center position of the conveyed object W.

First, as shown to Fig.7 (a), the 1st setting member 11a and the 2nd setting member 11b are located in the home position before a setting operation | movement start. In this state, the object to be conveyed W is closer to the abutting part 11c side than the abutting part 11d, and the center position X of the object to be conveyed W is at a position shifted from the setting position O.
Next, as shown in FIG. 7B, when the hydraulic cylinder 17a is driven and both rods start to protrude, the contact portions 11c and 11d of the setting members 11a and 11b are moved to the support shaft 14, that is, the setting position O. Start moving towards each.
Since the article to be transported W is close to the contact part 11c, the contact part 11c contacts the object to be transported W before the contact part 11d.
Then, as shown in FIG. 7C, after the contact portion 11c first contacts the transported object W, when the drive of the hydraulic cylinder 17a further proceeds, the contact portion 11c and the transported object W together with the frame 6 is moved toward the setting position O along the rails 5a and 5b. Finally, when the abutting portion 11d also abuts on the object to be conveyed W, the center position X of the object to be conveyed W coincides with the setting position O. That is, when the conveyed object W is clamped by the first regulating member 11a (contact part 11c) and the second regulating member 11b (contact part 11d) of the regulating part 11, the center position X of the conveyed object W is automatically set. In agreement with the regulation position O, the article W to be conveyed is regulated to the correct position.
In this way, the article W to be conveyed is regulated and fixed to the correct position and posture on the sub-conveying path 4 (frame 6).
In addition, after the contact part 11c contacts the transported object W, the transported object W does not slide on the rollers Ra and Rb until the contact part 11d contacts the transported object W. . This is because the friction between the sub-transport path 4 and the rails 5a and 5b is much smaller than the friction between the conveyed object W and the rollers Ra and Rb.

Thereafter, the object to be transported W that has been corrected and fixed at the correct position and orientation on the sub transport path 4 is subjected to predetermined processing and processing.
When the hydraulic cylinder 17a is driven and the rods are moved backward after the processing is completed, the setting members 11a and 11b start to move toward the home position.
Next, when the pressing pieces 8 a and 8 b are retracted and the rollers Ra and Rb are reversed, the article W to be conveyed is sent from the sub-conveying path 4 toward the main conveying path 1.

The regulation unit 11 having the above configuration does not slide with the movement of the article to be conveyed W when the article to be conveyed W is regulated in the correct posture and position in the sub-conveyance path 4. There is no generation of scratches and therefore no generation of abrasion powder. In addition, the to-be-conveyed object W can be regulated smoothly and efficiently with a small driving force.
Therefore, it can be set as the regulation apparatus especially suitable for the manufacturing line of medical goods, foodstuffs, or an electronic device on which clean environment is a condition.

8 and 9 show a setting unit 31 according to another embodiment of the present invention.
8 corresponds to FIG. 5 described above, and FIG. 9 corresponds to FIG. 6 described above. The setting part 31 is a simplified type in which the fixing stopper 18 is provided instead of the second setting member 11b and the link mechanism 13 is omitted. Note that the configuration of the sub-transport path 4 is the same as described above.

The fixed stopper 18 is provided in a fixed position similar to the above-described second regulating member 11b, and the installation position is always conveyed from the main conveyance path 1 side via the chain conveyors 2a and 2b with sufficient margin. It is decided to accept the object W.
Then, as shown in FIGS. 8 and 9, when the first setting member 11a is moved by the hydraulic cylinder 17a, the conveyed object W is clamped by the first setting member 11a (contact portion 11c) and the fixed stopper 18. The center position X of the object to be conveyed W coincides with the regulation position O ′, and the object to be conveyed W is regulated to the correct position.
In this way, the article W to be conveyed is regulated and fixed to the correct position and posture on the sub-conveying path 4 (frame 6).

  Even in the setting unit 31 having the above-described configuration, when the object to be conveyed W is adjusted to the correct posture and position in the sub-conveying path 4 (frame 6), there is no sliding accompanying the movement of the object to be conveyed W. There is no generation of scratches on the bottom surface of the object to be conveyed W, no generation of abrasion powder, and the normal movement of the object to be conveyed W can be smoothly performed with a small driving force.

  As mentioned above, although one embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to the above-described embodiment, and the design can be changed without departing from the gist of the present invention. It is.
