Description

  The present invention relates to a transfer device for loading and unloading (transferring) workpieces to and from a large number of shelves, and more particularly to a mounting structure for a lifting platform for moving up and down a transfer machine for loading and unloading workpieces in this transfer device. It is.

  This type of transfer device, and the lifting platform that constitutes it, are intended to move and lift the transfer machine for loading and unloading work to and from the shelf according to the position of the shelf. It is a big success in the warehouse. Moreover, in this kind of transfer apparatus, in order to suspend both sides of the lifting platform, as shown in FIGS. 1 to 4, the columns (devices) are two on the left and right with respect to the moving direction of the transfer apparatus. There is a need. There are various transfer machines such as a scalar arm and a slide fork, and the transfer machine is appropriately selected according to the type of workpiece.

  Further, in this type of transfer device, the lifting platform must be guided up and down with respect to the column device, but when the workpiece becomes large and heavy, the lifting platform is also lifted and lowered. Since it is necessary to ensure that the work can be performed and the size of the shelf is increased with the increase in the size of the workpiece, the gravitational load on the lifting platform is increased through the transfer machine.

As a guide device for the lifting platform in such a transfer device, it is also described in detail in Patent Document 1 filed by the applicant.
Japanese Utility Model Publication No. 5-22491, FIG. 2 or FIG.

  This Patent Document 1 describes an invention relating to a “lift platform guide device” which is made for the purpose of “preventing a lift platform that moves up and down along a pair of left and right vertical guide rails from rattling left and right”. As shown in FIG. 14, this “elevating table guide device” has “a guide roller 18 on at least one side of the elevating table 12 is provided on the elevating table 12 so as to be movable left and right, and a guide rail is provided by a spring 19. It is biased toward the 11 side ”.

  The “elevator guide device” described in Patent Document 1 describes that “when the mast is high, the mast bends away from each other in the central part of the height or in a direction close to each other. Since the distance changes in the height direction, the distance between the left and right guide rails also changes. As a result, a gap is generated between the guide rail and the guide roller of the lifting platform, and the lifting platform is rattled from side to side. This is an improvement over the prior art that there was a drawback, and by configuring as described above, “a guide roller on at least one side of the lifting platform is provided on the lifting platform so as to be movable left and right and is guided by a spring. Since it is biased toward the rail side, the guide rail and the guide roller of the elevator stand always maintain a close contact state ”.

  However, according to the subsequent study by the present inventor, the above configuration is sufficient when the connection of the lifting platform to the column (device) can be performed by “guide rollers and guide rails”. In the case of adopting the above, it has been found that a sufficient effect cannot be obtained with the above configuration.

  That is, as described above, in a transfer device that transfers heavy and large workpieces, the entire size of the transfer device has to be increased. However, the height has to be about 10 m. Then, the “span” at the top and bottom of these strut devices indicates whether the strut device itself has manufacturing errors, whether or not it is weighted by the work, and whether the work is supported at the upper end side or the lower end side. Depending on whether it is, it may be different.

  In other words, simply connecting the lifting platform on which the workpiece or the transfer machine is mounted to the column device side cannot respond to the above-described situation change. For example, in Patent Document 1, the guide rail and the lifting platform As the guide roller is mechanically forced, the smooth operation of the transfer device may be hindered.

  Therefore, the present inventors, etc., regarding the transfer device, how to ensure that the lifting and lowering operation of the lifting platform can always be performed stably even when the column device is temporarily enlarged. As a result of various studies, the present invention has been completed.

  That is, the first object of the present invention is to raise and lower the lifting platform even if an error occurs in the span above and below the column device or the column device and the support frame are slightly inclined. An object of the present invention is to provide a support structure for a lifting platform in a transfer apparatus that can be performed smoothly.

  Further, the second object of the present invention is that the support frame to which the lifting platform is connected is stably guided by the linear movement guide to the support device, and the torsional force applied through the workpiece or the like is applied. An object of the present invention is to provide a support structure for a lifting platform in a transfer apparatus that can sufficiently compete.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“It is a transfer device 100 that moves in a warehouse in which a large number of shelves 50 are arranged and puts workpieces in and out of each shelf 50,
The transfer device 100 includes a base 10 that moves in the warehouse, two left and right support devices 20 that are erected on the base 10, and a lift that is moved up and down with respect to the support devices 20. 30 and a transfer machine 40 installed on the lifting platform 30,
A support frame 32 is attached to each column device 20 so as to be movable up and down, and an end of the lifting platform 30 is connected to a lower end of each support frame 32 via a pin 33 inserted into a round hole 33a of the support frame 32. The mounting structure of the lifting platform 30 in the transfer device 100, wherein the lifting platform 30 and each support frame 32 are tiltable in the left-right direction via the pins 33 "
It is.

  That is, the transfer apparatus 100 related to this claim 1 moves in and out of a warehouse where a large number of shelves 50 are arranged, and puts and removes workpieces to and from each shelf 50. As shown in FIG. A base 10 that moves in the warehouse, two strut devices 20 erected on the base 10, a lift 30 that is moved up and down with respect to each of the struts 20, and the lift 30 It is comprised with the transfer machine 40 installed.

  Further, in this transfer device 100, the lifting platform 30 is supported by a support frame 32 that is mounted so as to be movable up and down with respect to the column device 20. However, as shown in FIG. In addition to the direct attachment of the frame 32, the case where the support frame 32 is indirectly attached to the support device 20 via the guide unit 31 as shown in FIG.

  In addition, the transfer device 100 according to the first aspect of the present invention is provided with a lifting platform when each support device 20 itself and the support frame 32 attached to the support device 32 so as to freely move up and down are inclined with respect to the vertical direction due to a manufacturing error or the like. 30 and the support frame 32 can be tilted via the pins 33 inserted into the respective round holes 33a, and the “unreasonable force” based on the tilt is transferred while maintaining the horizontal state of the lifting platform 30. This is so arranged that it is not added to each part of the mounting apparatus 100.

  Now, as shown in FIG. 2 or FIG. 3, the transfer apparatus 100 having the above configuration moves on the rail 21 in the warehouse where a large number of shelves 50 are arranged, and the shelves 50 to and from which workpieces are put in and out. As shown in FIG. 4, the lifting platform 30 is moved up and down to the corresponding position on the shelf 50. Thereafter, the transfer machine 40 on the lifting platform 30 is operated, the scalar arm or fork is extended to the shelf 50, the workpiece is moved in and out, and the scalar arm or fork is returned to the original position again to move the workpiece in and out. It is completed.

  In addition, as shown in FIG. 2 or FIG. 3 and FIG. 4, the above-described lifting platform 30 is attached to the two strut devices 20 constituting the transfer device 100 so as to be movable up and down. In the best mode shown in FIG. 2, the lifting platform 30 can be attached to the column device 20 such that it can be tilted to the column device 20 via the support frame 32. In the best mode shown in FIG. The support frame 32 is tiltably attached via the unit 31.

  Of course, these support frames 32 are supported on the respective strut devices 20 by a rope such as a chain or a linear movement guide 60 which will be described later, and each strut is driven by a driving device (not shown) provided in each strut device 20. These support frames 32 are moved up and down by synchronously driving them.

  Then, as shown in FIG. 2 or FIG. 3, the end of the lifting platform 30 is connected to the lower end of the support frame 32 via a pin 33 so as to be tiltable. Thus, for example, the elevator block 30a is fixed to the upper surface of the elevator 30, and a round hole 33a is formed in the elevator block 30a. On the other hand, a support frame side block 32b is fixed to the lower end of the support frame 32, and a round hole 33a is also formed in the support frame side block 32b. Then, the above-described pin 33 is inserted into each of the round holes 33a formed in each of the elevator block 30a and the support frame block 32b configured as described above, and the elevator 30 is connected via this pin 33. It is connected to the support frame 32 so as to be tiltable. In the best mode to be described later, this pin 33 is arranged at each corner portion of the lifting platform 30 having a rectangular shape in plan view shown in FIG. A total of four are used.

  With the configuration as described above, in the mounting structure of the lifting platform 30 in the transfer device 100 according to claim 1, the four positions corresponding to the end portions of the lifting platform 30 on the side of each column device 20 are each round holes. Since it is connected with the lower end part of the support frame 32 via the pin 33 inserted in 33a so that tilting is possible, the lifting platform 30 can tilt with respect to each support frame 32 located on both sides. is there.

  Here, if the lifting / lowering amount of the support frame 32 is slightly different on both sides, there is a slight dimensional error in the height direction in each strut device 20, and the transfer machine 40 on the lifting / lowering platform 30 is moved to the workpiece. When the torsional force when supporting the column is applied to each column device 20 or the platform 30 itself, the span between the column units 20 is different from the other parts, and each column device 20 is inside, that is, the platform. This phenomenon manifests itself as a slight fall on the upper side of the rail 30, and an unreasonable force is applied to the rails 21 and the like on the column device 20 side, so that the smooth lifting of the elevator 30 is hindered. This is because the weight of the work supported by each of the support devices 20 is added to the lift 30 and the transfer device 40 thereon.

  However, in the mounting structure according to the first aspect, since the lifting platform 30 is connected to the support frame 32 by the pin 33 inserted into the round hole 33a, the dimensional change caused by the difference between the spans between the two strut devices 20 is achieved. The inclined state is absorbed by each pin 33 and the round hole 33a, and an excessive force is not applied to each connecting portion or supporting portion in the transfer device 100.

  Therefore, in the support structure of the lifting platform 30 in the transfer device 100 according to the first aspect, even if an error occurs in the span between the column devices 20, the lifting platform 30 and the support frame 32 are inserted into the respective round holes 33a. Since it can be tilted via the pin 33, the lifting platform 30 can be moved up and down smoothly.

In order to solve the above problems, the means taken by the invention according to claim 2
“It is a transfer device 100 that moves in a warehouse in which a large number of shelves 50 are arranged and puts workpieces in and out of each shelf 50,
The transfer device 100 includes a base 10 that moves in the warehouse, two left and right support devices 20 that are erected on the base 10, and a lift that is moved up and down with respect to the support devices 20. 30 and a transfer machine 40 installed on the lifting platform 30,
A support frame 32 is attached to each column device 20 so as to be movable up and down, and an end of the lifting platform 30 is connected to one lower end of each of the support frames 32 via a pin 33 inserted into a round hole 33a of the support frame 32. In addition, the other end portion of the lifting platform 30 is connected to the other lower end of the support frame 32 via a pin 33 inserted into a long hole 33b of the support frame 32 that allows horizontal movement of the pin 33,
The elevator 30 and the support frames 32 can be tilted in the left-right direction via the pins 33, and the elevator 30 and the support frame 32 can be slid in the left-right directions via the pins 33. The mounting structure of the lifting platform 30 in the transfer device 100 characterized in that "
It is.

  That is, in the mounting structure of the lifting platform 30 in the transfer device 100 according to this second aspect, the basic portion and a pin in which one end of the lifting platform 30 is inserted into the round hole 33 a at one lower end of the support frame 32. 33 is the same as that of the above-mentioned claim 1 in that it can be tilted and connected to the other lower end of the support frame 32 through a pin 33 inserted into a long hole 33b whose major axis is in the horizontal direction. The difference is that the other end of the lifting platform 30 is slidably connected.

  Further, in this transfer device 100, the lifting platform 30 is supported by a support frame 32 that is mounted so as to be movable up and down with respect to the column device 20. However, as shown in FIG. In addition to the direct attachment of the frame 32, as shown in FIG. 3, it includes the case where the support frame 32 is indirectly attached to the support device 20 via the guide unit 31 as in the case of the above-described first aspect. .

  The transfer device 100 according to the second aspect of the present invention has a lifting platform that is tilted with respect to the vertical direction due to a manufacturing error or the like on each column device 20 itself or on the support frame 32 that is attached to the column device 20 so as to be movable up and down. 30 and the support frame 32 can be tilted via pins 33 inserted into the respective round holes 33a, and can be slid at the connecting portion by the pins 33 inserted into the respective elongated holes 33b. The “unreasonable” based on the error and the inclination is prevented from occurring in each part of the transfer apparatus 100 while maintaining the horizontal state.

  In other words, in the mounting structure according to the second aspect, the tiltable connection of the lifting platform 30 to the support frame 32 on the side of each column device 20 is made possible by a round hole 33a shown in FIG. 9 and a long hole 33b shown in FIG. These two types of holes are performed using the pins 33 inserted into the holes.

  As a result of the above, the tiltable connection of the lifting platform 30 to the one support frame 32 is performed by adopting the round hole 33a shown in FIG. 9 and the pin 33 inserted therethrough. The portion thus performed exhibits the same function as in the first aspect.

  On the other hand, the elevating platform 30 can be tilted and connected to the other support frame 32 using the elongated hole 33b whose major axis is in the horizontal direction and the pin 33 inserted through the elongated hole 33b. The side on which the pin 33 is formed (in the best mode to be described later is the lifting platform 30 side) moves even slightly in the horizontal direction with respect to the side to which the pin 33 is connected (in the best mode, the support frame 32 side). It has become possible.

  For this reason, when an error in the horizontal direction occurs in the connection portion of the lifting platform 30 with respect to the both support frames 32, this error is caused by the long hole 33b having the long axis in the horizontal direction and the pin 33 inserted through the hole 33b. It will be absorbed in the part connected via. That is, the lifting amount of the support frame 32 is slightly different on both sides, there is a slight dimensional error in each column device 20 in the height direction, and the transfer machine 40 on the lifting platform 30 supports the workpiece. Even if a horizontal error occurs between the lower end of the support frame 32 and the end of the lifting / lowering base 30 due to the torsional force applied to each of the supporting pillars 20 and the lifting / lowering base 30 itself. Is absorbed by the elongated hole 33b and the pin 33 inserted therethrough.

  Of course, in the portion of the lifting platform 30 that is connected to the support frame 32 by the pin 33 inserted into the round hole 33a, the span dimension between the two strut devices 20 is the same as in the case of the mounting structure of claim 1. As described above, the inclination of each support frame 32 based on the change is absorbed by each pin 33 and an excessive force is not applied to each connection part or support part.

  Therefore, in the support structure of the lifting platform 30 in the transfer device 100 according to the second aspect, even if an error occurs in the span between the column devices 20, the error is caused by the horizontal direction of the round hole 33a and the long axis. Each pin 33 inserted into the elongated hole 33b can be reliably absorbed, and the lifting platform 30 can be moved up and down smoothly.

Moreover, in order to solve the said subject, the means which invention which concerns on Claim 3 took about the attachment structure of the raising / lowering base 30 in the transfer apparatus 100 of the said Claim 1 or Claim 2,
“The connection of each support frame 32 to each strut device 20 is performed using the linear movement guide 60 assembled to the rail 21 provided in the vertical direction of each strut device 20”.
It is.

  That is, in the mounting structure of this third aspect, attention is paid to the connection of each support frame 32 to each column device 20 of the transfer device 100, and this connection is provided in the vertical direction of each column device 20. This is performed using a linear movement guide 60 assembled to the rail 21. Of course, it goes without saying that the connection of each support frame 32 to each column device 20 includes the case where the support unit 32 is performed using the guide unit 31 shown in the best mode.

  As shown in FIG. 13, the linear movement guide 60 has a large number of balls 61 interposed between the case body and the rail 21, and each ball 61 rolls in the case body. The reciprocating motion of the support frame 32 or the guide unit 31 with respect to the rail 21 is made stable. In other words, the linear movement guide 60 connects the case body of the linear movement guide 60 and the rail 21 with a large number of balls 61 interposed. In addition, the weight of the lifting platform 30, the transfer machine 40 thereon, and the work supported by the transfer machine 40 is supported by the ropes or chains constituting each support device 20, and The lifting platform 30 can be connected in a stable state at all times.

  Therefore, the mounting structure according to the third aspect exhibits the same function as that according to the first or second aspect, and can move the elevating table 30 up and down with respect to each column device 20 in a stable state by the linear movement guide 60 at all times. It is a thing.

As described above, in the present invention,
“It is a transfer device 100 that moves in a warehouse in which a large number of shelves 50 are arranged and puts workpieces in and out of each shelf 50,
