Description

  The present invention relates to a vibration isolation pallet on which a transported object is placed and transported.

  Currently, as a method of transporting a transported object, a pallet on which the transported object is placed is transported by a transport means, for example, a vehicle such as a truck or a railway wagon, and the pallet is transported to a factory or a warehouse using a transport means such as a forklift A carrying method for carrying in is known. However, transported objects such as electronic devices and precision devices are vulnerable to vibrations and impacts due to their structures, and may be damaged by vibrations and impacts during transport.

  For example, when a transported object is transported using a vehicle, since the suspension is a leaf spring, the vibration damping ability is poor, and vibrations and impacts caused by unevenness of the travel path are easily transmitted to the loading platform. For this reason, it is known that by using a vehicle having an air suspension in the vehicle, vibration is absorbed and attenuated and damage to the conveyed product is prevented. However, a vehicle equipped with an air suspension is expensive, and there is a problem that the transportation cost increases.

  When a transported object is transported using a freight car, large vibrations or impacts are generated depending on the rail installation status. In addition, slight vibration due to running also occurs. However, since the suspension of the freight car is also a leaf spring, and vibration and shock cannot be attenuated, the freight car is unsuitable for transporting conveyed items. Further, when a pallet is conveyed by a forklift, vibration and impact are generated by the forklift traveling and the movement of the pallet.

  In view of this, there has been known a vibration-isolating pallet that has a vibration-isolating effect by reducing vibrations and impacts applied to the conveyed object during conveyance. Such a vibration isolating pallet has a base frame to be installed on the conveying means and a mounting frame on which a conveyed product is placed, and an elastic member that attenuates vibration is provided between the base frame and the mounting frame. ing.

  Further, in order to be able to damp not only the vertical direction but also the horizontal direction vibration, a vibration isolation pallet (see, for example, Patent Document 1) provided with springs in the vertical and horizontal directions is known as an elastic member. Furthermore, a vibration-isolating pallet (for example, a patent) that has protrusions with different heights on the upper and lower surfaces of the elastic member, changes the protrusions that contact the pallet by acceleration applied to the conveyed object, and changes the elastic force that supports the conveyed object. Document 2) is also known.

JP 2002-145269 A JP 2002-145267 A

  The above-described vibration isolation pallet has the following problems. That is, in the above-described vibration-isolating pallet, vibration is attenuated in two directions, the horizontal direction and the vertical direction, and the elastic force that supports the mounting pallet on which the object is mounted is changed based on acceleration or the like. It has a damping function that attenuates. However, depending on the weight, center of gravity, etc. of the transported object placed on the mounting pallet, an excessive load may be applied to some elastic members, etc. It is not performed and the vibration isolation effect may be low.

  For example, when using an elastic member suitable for a certain transported object to provide a vibration-isolating pallet having a high vibration-isolating effect, a high vibration-isolating effect may not be obtained by transporting other transported objects. That is, since an appropriate elastic member differs depending on the type, amount, center of gravity, and the like of the object to be placed, it has been difficult to obtain a vibration-isolating pallet having a high vibration-isolating effect.

  Therefore, an object of the present invention is to provide a vibration isolation pallet having an appropriate vibration isolation effect regardless of the object to be placed.

  In order to solve the problems and achieve the object, the vibration isolation pallet of the present invention is configured as follows.

In addition, the base frame 11 crosses the first frame member 21 and the first frame member 21 so as to pass the first frame member 21 and the second frame member 22 facing each other of the first frame body 23, respectively. A first reinforcing portion 24 connected to the body 23 is included. As described above, the base frame 11 is formed in a rectangular lattice shape by connecting the first frame body 23 with the first reinforcing portion 24.

In addition, the third frame member 27 and the third frame member 26 intersect each other so that the mounting frame 12 passes the third frame member 26 and the fourth frame member 27 facing each other of the second frame body 28. The second reinforcing portion 29 is connected to the second frame body 28. In this manner, the mounting frame 12 is formed in a square lattice shape by connecting the second frame body 28 with the second reinforcing portion 29.

  The number and shape of the frame members 21, 22, 26, and 27 of the base frame 11 and the mounting frame 12 are such that the strength of each of the frames 11 and 12 can be formed to a predetermined strength, and the transported object W to be mounted. If it is a shape which does not fall from a grid | lattice-like opening, it can set suitably.

  The vibration isolation member 13 can always connect the base frame 11 and the mounting frame 12, can connect the first vibration isolation member 31 that elastically supports the mounting frame 12, and the base frame 11 and the mounting frame 12, and And a second vibration isolation member 32 that can elastically support the mounting frame 12 when the base frame 11 and the mounting frame 12 are connected.

  The first vibration isolation member 31 is provided by connecting the first frame body 23 and the second frame body 28 to the four corners of the first frame body 23 and the second frame body 28. The first vibration isolation member 31 is formed to be able to elastically support the mounting frame 12 with respect to the base frame 11. The first vibration isolation member 31 includes vibration isolation means 34 provided at the four corners of the first frame body 23, and connection members 35 provided at the four corners of the second frame body 28.

  The vibration isolation means 34 is an elastic member capable of vibration isolation, for example, a cylindrical rubber member, and is formed so as to be able to dampen vibration in two directions of X, Y direction (horizontal direction) and Z direction (compression direction). Has been. Hereinafter, the vibration isolation means 34 will be described as the vibration isolation rubber 34.

  The anti-vibration rubber 34 is formed so as to be fixed to the first frame body 23 by, for example, a bolt (not shown). Further, the vibration-proof rubber 34 is provided with a bolt part 34 a that can be connected to the connecting member 35 so as to protrude from the central part of the upper surface thereof. As such an anti-vibration rubber 34, for example, Kurashiki Kako Co., Ltd. KB type circular anti-vibration rubber (model number: KB-40-33H etc.) is used.

  The connecting member 35 is fixed to the four corners of the second frame body 28 by welding or fastening members. For example, the connecting member 35 is bent in a U shape in which a flat portion 35 a parallel to the second frame body 28 protrudes toward the first frame body 23. The connecting member 35 is formed such that the flat portion 35 a can come into contact with the upper surface of the vibration-proof rubber 34.

  The flat surface portion 35a is formed with an insertion hole 35b through which the bolt portion 34a can be inserted. The flat portion 35a is formed by opening a part of the side surface so that the bolt portion 34a inserted through the insertion hole 35b can be fastened with a fastening member such as a nut. That is, the connecting member 35 is formed so as to be able to connect the first frame body 23 and the second frame body 28 by being connected to the anti-vibration rubber 34.

  As shown in FIGS. 1-5, the 2nd vibration isolator 32 is provided in four places so that the center part of 4 sides of the 1st frame 23 and the 2nd frame 28 can be connected. The second vibration isolation member 32 is formed so as to support the mounting frame 12 together with the first vibration isolation member 31 with respect to the base frame 11 by connecting the first frame body 23 and the second frame body 28. .

  The second vibration isolation member 32 includes an anti-vibration rubber 34 provided at each of the central portions of the four sides of the first frame 23, and a fixing member 36 that is fixed to one of the first frame 23 or the second frame 28. , And a mounting plate 37 for attaching the fixing member 36 to one of the first frame body 23 and the second frame body 28. Since the vibration isolating rubber 34 is the same as the anti-vibration rubber 34 used for the first vibration isolating member 31, detailed description thereof is omitted here.

  As shown in FIGS. 1 to 6, the fixing member 36 is connected to the anti-vibration rubber 34, thereby connecting the first frame body 23 and the second frame body 28 via the anti-vibration rubber 34. It is. The fixing member 36 includes a pair of first attachment surfaces 36a connected to the attachment plate 37 by a fastening member S such as a bolt. The fixing member 36 is provided in parallel with the first mounting surface 36a so as to be spaced apart in a direction (Z direction) orthogonal to the main surface direction of the first mounting surface 36a, and any one of the main surfaces is vibration-proof rubber. 34 is provided with a second mounting surface 36b that abuts the upper surface of 34.

  The fixing member 36 includes a continuous portion 36c that continues the first mounting surface 36a and the second mounting surface 36b. The fixing member 36 includes a reinforcing wall 36d provided continuously on one side of the continuous portion 36c and the second mounting surface 36b. Such a fixing member 36 is formed by bending a plate material.

  The first attachment surface 36a has an insertion hole 36e through which the fastening member S is inserted. The second mounting surface 36b has a notch portion 36f through which the bolt portion 34a can be inserted and continuous with the side portion of the other second mounting surface 36b where the reinforcing wall 36d is not provided. That is, the fixing member 36 is formed to be slidable in the horizontal direction in a state where the bolt part 34a is inserted into the notch part 36f of the second mounting surface 36b. The second mounting surface 36b is formed with a seating surface of a member to be fastened N such as a nut that is screwed into a bolt portion 34a inserted through the notch portion 36f.

  The distance from the first mounting surface 36 a to the second mounting surface 36 b of the fixing member 36 (height of the fixing member 36) is formed with the same dimension as the height of the connecting member 35. That is, when the second mounting surface 36 b is fixed to the vibration isolating rubber 34 and the first mounting surface 36 a is fixed to the mounting plate 37 of the second frame 28, from the vibration isolating rubber 34 to the second frame 28. Is made uniform so that the load applied to the anti-vibration rubber 34 is locally increased (collapsed locally).

  The attachment plate 37 is provided at the center of the first frame body 23 and the second frame body 28. More specifically, the mounting plate 37 is provided in a pair adjacent to the anti-vibration rubber 34 on the four sides of the first frame body 23, and the second frame body is opposed to the pair of mounting plates 37. A pair is provided on the four sides of 28. The mounting plate 37 is provided across the first frame body 23 and the second frame body 28, and is provided with a screw hole 37a into which the fastening member S can be screwed.

  In the vibration isolating pallet 1 configured as described above, the mounting frame 12 is always supported on the base frame 11 via the vibration isolating rubber 34 by the first vibration isolating member 31 and, if necessary, the second vibration isolating pallet 1 is provided. The mounting frame 12 is also supported by the base frame 11 in the vibration member 32.

  More specifically, the vibration isolation pallet 1 connects the anti-vibration rubber 34 fixed to the first frame body 23 and the connecting member 35 fixed to the second frame body 28 by the bolt part 34a and the fastened member. Thus, the base frame 11 and the mounting frame 12 are connected, and the mounting frame 12 is always elastically supported by the base frame 11.

  Further, the vibration isolation pallet 1 fixes the fixing member 36 to the mounting plate 37 of the second frame body 28 according to the weight and the center of gravity of the transported object W placed on the mounting frame 12, and the vibration isolating rubber 34. And the fixing member 36 are connected by the bolt part 34a and the fastened member N.

  Thus, the vibration isolation pallet 1 supports the mounting frame 12 by changing the number of second vibration isolation members 32 that support the mounting frame 12 (connect the base frame 11 and the mounting frame 12). The elastic coefficient and balance of the anti-vibration rubber 34 are variable.

Next, the attachment of the second vibration isolation member 32 will be described with reference to FIGS.
As shown in FIGS. 3 and 5, the second vibration isolation member 32 fixes the first member 23 and the second frame by fixing the fixing member 36 to one of the first frame 23 or the second frame 28. The body 28 is formed to be connectable.

  First, the connection of the first frame body 23 and the second frame body 28 by the second vibration isolation member 32 will be described. As shown in FIG. 4, first, the first attachment surface 36 a of the fixing member 36 is arranged on the attachment plate 37 of the second frame body 28, and the second attachment surface 36 b is arranged on the vibration isolating rubber 34 of the first frame body 23. In this state, the fastening member S is inserted into the insertion hole 36e of the first attachment surface 36a, and the fastening member S is screwed into the screw hole 37a of the attachment plate 37, thereby fixing the fixing member 36 to the second frame body 28. To do. At this time, the bolt part 34a of the anti-vibration rubber 34 is inserted into the notch part 34f.

  When the first frame member 23 and the second frame member 28 are already connected by the first vibration isolation member 31, the fixing member 36 is slid in the horizontal direction so that the second frame member 28 and the vibration isolator rubber are used. 34 and the bolt portion 34a may be inserted through the notch 36f. 2 and 4, when the first frame body 23 and the second frame body 28 are separated, the first mounting surface 36a of the fixing member 36 is first fixed to the second frame body 28. Let me just let you.

  Next, the to-be-fastened member N is screwed into the bolt part 34a, and the vibration isolating rubber 34 and the fixing member 36 are fixed. As a result, as shown in FIG. 3, the fixing member 36 is supported by the vibration isolating rubber 34, and the second frame 28 is attached to the first frame 23, the first vibration isolating member 31 and the second vibration isolating member. 32 will be supported.

  Here, the second vibration isolation member 32 may connect the first frame body 23 and the second frame body 28 at all (four locations), or the first vibration isolation member 32 may be connected to the first vibration isolation member 32 by the first vibration isolation member 32. The frame body 23 and the second frame body 28 may be connected.

  Next, the case where the 1st frame 23 and the 2nd frame 28 are not connected by the 2nd vibration isolator 32 is demonstrated. First, the first attachment surface 36a of the fixing member 36 is brought into contact with the attachment plate 37 of the first frame 23, and the bolt part 34a is inserted through the notch part 36f. In this state, the fastening member S is inserted through the insertion hole 36e of the first attachment surface 36a, the fastening member S is screwed into the screw portion 37a of the attachment plate 37 of the first frame body 23, and the fixing member 36 is attached to the first frame. While being fixed to the body 23, the to-be-fastened member N is screwed together by the volt | bolt part 34a.

  Thereby, as shown in FIG. 5, the second vibration isolation member 32 is fixed to the first frame body 23, and the second vibration isolation member 32 is not fixed to the second frame body 28. That is, since the second vibration isolation member 32 does not connect the first frame body 23 and the second frame body 28, the mounting frame 12 is not elastically supported by the second vibration isolation member 32.

  As described above, the second vibration isolation member 32 has the first attachment surface 36 a of the fixing member 36 provided on either the attachment plate 37 of the first frame 23 or the attachment plate 37 of the second frame 28. The base frame 11 and the mounting frame 12 can be coupled, and the elastic support of the mounting frame 12 by the anti-vibration rubber 34 of the second vibration isolation member 32 can be arbitrarily changed.

  Therefore, the vibration isolation pallet 1 can elastically support the mounting frame 12 by the first vibration isolation member 31 and can change the elastic support and non-support of the mounting frame 12 by the second vibration isolation member 32. It becomes.

  In other words, the vibration isolation pallet 1 is made of the vibration isolation rubber 34 that supports the mounting frame 12 by changing the number and arrangement of the vibration isolation rubbers 34 that elastically support the mounting frame 12 by the second vibration isolation member 32. It becomes possible to change the support conditions such as the Z-direction support load, the vibration transmissibility, the eccentric load due to the center of gravity, and the acceleration. By making it possible to change the support condition of the mounting frame 12, the vibration isolation pallet 1 can set an appropriate support condition corresponding to the conveyed product W.

  Note that the support load is a load applied to one anti-vibration rubber 34 that supports the mounting frame 12. The uneven load is a load that differs at each position depending on the configuration of the mounting frame 12 and the center of gravity of the transported object W to be mounted, and the acceleration applied during vibration changes depending on the center of gravity. Further, the support conditions are conditions such as the number, type, and support load of the anti-vibration rubber 34 with respect to the size, shape, material, and the like of the conveyed product W and the mounting frame 12.

  The vibration isolating pallet 1 configured in this manner varies the vibration isolating rubber 34 that elastically supports the mounting frame 12 according to the center of gravity and the load (weight) of the conveyed product W placed on the mounting frame 12. Thus, it is possible to set appropriate support conditions for the center of gravity and load of the transported object W to be placed.

  For this reason, since the vibration isolation pallet 1 can elastically support the mounting frame 12 and the transported object W under optimal support conditions, a high vibration isolation effect is obtained, and the transported object W is transported. Vibration and impact can be reduced.

  By reducing vibration and impact, it is possible to prevent damage to the conveyed product W during conveyance by the conveyance means, to ensure product quality, and to improve conveyance reliability. Moreover, vibration and impact can be surely reduced by using an appropriate number and arrangement of the anti-vibration rubbers 34 not only for vehicles but also for transportation by rail transport or forklift as a transportation means. .

  For example, it is possible to transport a transported object W that is vulnerable to vibrations and shocks of precision instruments and the like that have been highly susceptible to damage when transported on a railway. That is, a modal shift is possible, and it is possible to reduce the cost due to conveyance and to reduce environmental problems.

  Furthermore, the vibration isolating pallet 1 can change its supporting load depending on the number of vibration isolating rubbers 34 and the like, and can greatly reduce vibration and shock. The transported object W can be transported, and the width of the transport means is widened. That is, the versatility of the vibration isolation pallet 1 can be improved.

  In addition, the second vibration isolation member 32 can fix the fixing member 36 only by fixing the vibration isolating rubber 34 and one of the mounting plates 37 of the first frame body 23 or the second frame body 28. Elastic support / non-support can be changed, and workability is also good. For this reason, the vibration isolation pallet 1 can cope with various and various transport conditions such as the transported object W and transport means, and the transport cost can be reduced.

  The determination of appropriate support conditions is performed, for example, by measuring impact values such as acceleration and amplitude values by a vibration test, a drop test, etc. with the transported object W placed, and based on the measurement data. The number and position of the anti-vibration rubber 34 may be determined. Moreover, you may determine optimal support conditions with another method. In other words, since an appropriate support condition may be appropriately determined according to the use application or the like, a specific method for determining the support condition of the mounting frame 12 is omitted in the present embodiment.

  As described above, according to the vibration isolation pallet 1 according to the present embodiment, the number and arrangement of the vibration isolating rubbers 34 that elastically support the mounting frame 12 can be changed, so that the weight of the transported object W can be changed. It becomes possible to set the support condition of the mounting frame 12 to the optimum support condition with respect to the center of gravity.

  Thereby, it becomes the vibration isolation pallet 1 which has the high vibration isolation effect (isolation efficiency) suitable for the conveyed product W, reduces the vibration and impact at the time of conveyance, prevents damage of the conveyed product W as much as possible, Quality can be ensured. Further, by improving the modal shift rate, the types of transport means and transportable objects can be increased, the transport effect can be improved, and the transport cost can be reduced.

  The present invention is not limited to the above embodiment. For example, in the above-described example, the mounting frame 12 has been described with a configuration in which five third frame members 26 and four fourth frame members 27 are used, but the present invention is not limited to this. Further, although the base frame 11 and the mounting frame 12 have different configurations, they may have the same configuration.

  In the above-described example, the first vibration isolation member 31 is provided at the four corners of the first and second frame bodies 23 and 28, and the second vibration isolation member 32 is the center of the four sides of the first and second frame bodies 23 and 28. However, the present invention is not limited to this. For example, the arrangement positions of the first vibration isolation member 31 and the second vibration isolation member 32 may be interchanged, and the number of the second vibration isolation members 32 may be eight instead of four, or may be another number. .

  Furthermore, the first vibration isolation member 31 has the same configuration as that of the second vibration isolation member 32, that is, all the vibration isolation members can be changed to support / unsupport the mounting frame 12 by the vibration isolation rubber 34. Alternatively, the mounting frame 12 may be supported by the anti-vibration rubber 34. However, in this case, it is a matter of course that the mounting frame 12 is supported by a plurality of vibration isolating rubbers 34 so that the mounting frame 12 can be supported.

  In the above-described example, the vibration isolating rubber 34 is used as the vibration isolating means 34. However, the present invention is not limited to this. For example, a spring member may be used as the vibration isolator 34, or an air cylinder or the like may be used. In addition, when using the vibration isolating rubber 34, other anti-vibration rubber may be used instead of the KB type round anti-vibration rubber (model number: KB-40-33H, etc.) manufactured by Kurashiki Kako Co., Ltd. A configuration in which various types of anti-vibration rubbers are appropriately used for the vibration isolation pallet 1 may be used. In addition, various modifications can be made without departing from the scope of the present invention.
