The present invention can efficiently transport and store a variety of parts by allowing each part storage space arranged in multiple stages according to the size of the part to be freely changed within a certain range when carrying various parts used for electronic products, automobiles, and the like. And a component transport cart.

In general, as a basic means used to simplify the storage and transport of various items in the production site, storage of goods, etc. of various products, a pallet that serves as a mobile stand.

The pallet is a two-stage structure in which an upper pedestal in which an article is placed on a lower pedestal placed on a floor is combined. The pallet is carried by putting a transport mechanism between the upper and lower pedestals, mainly for wood and metal. Or it is made of synthetic resin material, it is common that the article to be loaded on such a pallet has a shape that is easy to stack and stacked in multiple layers, such as hexahedral, columnar.

In addition, the article that is difficult to stack and stacked is loaded on a pallet in a box, or a pallet box in which a box is integrally coupled to an upper pedestal of the pallet.

However, pallets, which are most widely used in the industrial field, require a separate transportation means such as a forklift truck because they cannot move on their own, and the size of parts to be transported or stored are small or parallel to each other. In the case of a part having a shape that does not have a bottom and a bottom, it is inconvenient to use the pallet after putting the parts in a separate box.

Accordingly, various types of parts carrying carts, in which a plurality of wheels are coupled to the bottom, are used for carrying parts in the factory at that time.

Exemplary parts carrying carts, as shown in Figure 1, the bottom plate 11 of the square plate on which the moving wheels (W) coupled to the bottom surface; A plurality of posts 12 which are respectively upright of the bottom plate 11 at the top edges, and have a stacking cup C at an upper end thereof; The bottom plate 11 is composed of a metal mesh 13 and the like coupled to the upper edge portion and the posts 12 as a side wall, the bottom bar 11 has a structure in which the laminated bar (B) protrudes downward to be.

At this time, the post 12 and the laminated bar (B) may be a structure that is penetrated through the bottom plate 11 in a state formed integrally.

In the cart having the structure as described above, a space directly above the bottom surface of the bottom plate 11 surrounded by the metal net 13 becomes a component loading space. The carts are stacked, and the stacking bar (B) and the stacking cup (C) are used to facilitate stacking of the carts.

That is, the bottom surface of each laminated bar (B) is placed on the bottom surface of each laminated cup (C) of the lower cart.

Such a cart has a structure suitable for parts in a box or parts that are not affected by surface scratches, and since the parts cannot be directly contacted with each other in a state where they are loaded, the cart may be transported or flow between parts during loading. And there is a problem that the surface scratch will inevitably occur by the contact.

In addition, since the cart has only one loading space per unit, only one kind of parts needs to be transported, and when the number of parts is small, there is a problem in that the transport efficiency decreases.

Therefore, a cart was developed to separate the loading space into a plurality of load spaces as needed, but this also separates only the loading space into a plurality of load spaces. It is not possible to prevent the occurrence of surface scratches.

Particularly, in the case of electronic products, the number of parts thereof is large, and the sizes thereof are also very diverse, and surface scratches must not occur, so that the parts do not come into contact with each other during transportation, and a large amount of parts while preventing possible flows It should be possible to transport or store them together, but there is no proper structure of the cart.

Of course, there are carts with multiple shelves, but since the position of each shelf is fixed, it is not only difficult to carry and store components of various sizes, but also to prevent the flow of components during transportation. No means are provided.

The present invention has been made to solve various problems of conventional pallets or carts for transporting or storing various parts, and separate and transported various kinds of parts at the same time to prevent flow of parts during transportation. In addition, it is an object of the present invention to provide a component transport cart that can freely change the loading space for each component within a certain range according to the size of the component.

The above object of the present invention is achieved by a shelf frame which can be rotated only in the upper portion thereof in a horizontal state and a partition member free of adjustment of the engagement position within the shelf frame.

The parts transport cart of the present invention allows the transport or storage of a plurality of parts while preventing contact between the parts, and also allows the stowage space to be adjusted according to the size of the parts, while at the same time moving parts for transport The technical feature is to have a function to prevent the flow of these.

As described above, the cart of the present invention includes a bottom plate coupled to a plurality of moving wheels on a bottom thereof and forming an outer shape of a square plate or board; Two pairs of posts each uprightly coupled to four corners of the bottom plate; A plurality of shelf frames which are detachably coupled to both rear portions of the rear end to a pair of rear posts in a 1: 1 correspondence; The upper part of each post is composed of a top plate and the like coupled to each corner portion, looking at each as follows.

The bottom plate may be made of a single sheet of material having an appropriate strength, but it is also preferable to make it prefabricated so that it can be easily stored by being able to assemble in various shapes and sizes and to be disassembled. It consists of a plurality of horizontal members and a plurality of vertical members having a rectangular shape that is several times longer than the width of the width, and allows the horizontal and vertical members to be separated orthogonally to each other and to be detachably coupled to each other. The wheels can also be made in combination.

Posts, the upper and lower ends of the upper plate and the bottom plate, respectively, through each of the post coupling holes provided in the four corners of each of the coupling member is inserted into the post coupling hole in close contact with the bottom surface of the bottom plate, The upright member is screwed into the connecting member and the lower end portion is inserted into the interior through the post coupling hole upper opening of the bottom plate, and is composed of a laminated member coupled to the upper surface of the upright member to penetrate the top plate.

At this time, the connecting member is a plate-shaped lower support plate in which the upper surface is in close contact with the bottom surface of the bottom plate, a downwardly open type laminated cap fixedly coupled to the bottom of the lower support plate, fixedly coupled to the upper surface of the lower support plate and inserted into the post coupling hole It consists of a cylindrical lower socket formed with threads on the inner circumferential surface, the upright member has a circular cross-section, such as a circular tube, rod, etc., the length is relatively long compared to the cross-sectional dimension and a stick or bar shape provided with a thread on the outer peripheral surface of the lower end, The outer peripheral surface of the lower end of the screw is coupled to the inner peripheral surface of the lower socket of the connecting member.

And, the laminated member, the upper support plate is coupled to the upper end of the upright member and the upper surface is in close contact with the bottom surface of the upper plate, the upper socket coupled to the upper surface of the upper support plate and positioned inside the post coupling hole of the upper plate, and the upper socket It consists of a laminated rod protruding above the upper surface of the upper plate in the state in which the lower outer peripheral surface is screwed to the inner peripheral surface of the.

That is, when the cart of the present invention is stacked, the stacking cap of the upper cart is placed on the upper surface of the stacking rod of the lower cart, and the stacking cap of the connecting member has an upwardly convex cross-sectional shape which is opened downward so that the stacking structure can be stably maintained. Have

The shelf frame is a rectangular frame in which a plurality of rear ends are separated into a pair of rear posts, respectively, and a plurality of shelves are coupled in multiple stages so as to be movable up and down along the outer peripheral surface of the post.

And, each shelf frame, the hinges are coupled to both sides of the rear end, one hinge member constituting each hinge is fixedly coupled to the shelf frame, the other hinge member rotatable with respect to one hinge member is the outer peripheral surface of the post It is coupled to the rear post so as to be movable, the other hinge member is a structure that can be fixed to the outer peripheral surface of the post by a stop member, such as a bolt through the coupling from the outer surface to the through-hole through the post.

At this time, the two hinge members are preferably to be unfolded up to 180 ° in the overlapping state.

That is, each shelf frame is coupled to only a pair of rear posts, not front posts, so that the two hinge members are only extended up to 180 ° as described above, so that the hinge members provided on both sides of the rear end of the shelf frame, respectively. In a state where the position is fixed at an appropriate position on the rear post outer circumferential surface as required, the shelf frame can be rotated in the direction immediately above the horizontal plane around the rotating coupling of the hinge, but cannot be rotated in the direction directly below the horizontal plane. .

However, in the case where the pivot angle of the two hinge members is greater than 180 °, a separate means must be provided to prevent the shelf frame from falling below the horizontal plane.

By allowing the front end of the shelf frame to be rotated in the direction immediately above the horizontal plane as described above, it is possible to easily accumulate or withdraw products in each shelf frame.

The top plate has the same structure as the bottom plate except for the wheels, and is for stably standing two pairs of posts together with the bottom plate.

That is, one pair of rear posts of the two pairs of posts are respectively coupled to the bottom plate and both rear ends of the shelf frame to form a stable coupling structure, but the one pair of front posts are coupled only to the bottom plate, thus providing a stable upright structure. Can not have a bar, by being coupled to the top of all four posts at the same time allows the posts to be stably upright.

Details of the object and technical configuration of the present invention and the resulting effects thereof will be clearly understood by the following detailed description with reference to the drawings showing preferred embodiments of the present invention.

Fig. 2 is a perspective view of the component transport cart of the present invention, a partial side view is shown in Fig. 3, a perspective view of the bottom plate is shown in Fig. 4, a cross-sectional view of the bottom plate is shown in Fig. 5, an exploded view of a post in Fig. 6, and a shelf frame is shown in Fig. 7. A perspective view and a side view of the shelf frame shown in FIG. 8 is shown.

As shown in the parts carrying cart of the present invention,

A bottom plate 21 having a plurality of wheels W coupled thereto;

An upper plate 22 positioned directly above the bottom plate 21 to be parallel to the bottom plate 21;

Two pairs of posts 23 having upper and lower ends penetratingly coupled to four corner portions of the bottom plate 21 and the upper plate 22, respectively;

Of the two pairs of posts 23, both sides of the rear end correspond 1: 1 to the pair of rear side posts so that the up / down movement along the outer periphery of the rear pair of posts and the front end can be rotated directly in the horizontal direction. And are coupled to each other, and are composed of a plurality of shelf frames 24 or the like forming a multi-stage structure between the bottom plate 21 and the top plate 22.

Looking at each component of the cart of the present invention configured as described above in more detail as follows.

The bottom plate 21 and the top plate 22 may be made of a single sheet of material 21C, but for assembly to various sizes, a plurality of horizontal members having a rectangular planar shape that is relatively longer than several times longer than the width thereof. 21A and the horizontal member 21A are laminated orthogonally coupled to each other, and may be composed of a plurality of vertical members 21B having a rectangular planar shape that is relatively longer in length than the width like the horizontal member 21A. The four corner portions of the 21 and 22 are formed through the post coupling hole (H) for penetrating the two pairs of posts (23).

At this time, when the bottom plate 21 and the top plate 22 has a prefabricated structure, the bottom plate 21 and the top plate 22 may be distorted during loading storage or transfer due to the load of the parts.

Therefore, in the case of the prefabricated reinforcement to prevent the deformation of the assembly shape of the bottom plate 21 and the top plate 22 may be necessary, which is well known in various ways, for example, a method of padding the metal reinforcement plate, etc. As can be made, the description thereof will be omitted.

The post 23 is composed of a connecting member 23A, an upright member 23B and a stacking member 23C, and the connecting member 23A has a lower portion in which an upper surface is tightly coupled to the bottom of the bottom plate 21. Stacked on the bottom surface of the lower socket 23A2 and the lower support plate 23A1 which are upright coupled to the support plate 23A1 and the upper surface of the lower support plate 23A1 and positioned in the post coupling hole H of the bottom plate 21. It is comprised by the cap 23A3.

In addition, the upright member 23B is a body of the post 23, and a thread is formed on the outer peripheral surface of the lower end so that the lower end thereof can be screwed to the inner peripheral surface of the lower socket 23A2, and its length is relatively longer than the cross-sectional dimension. , Stick shape such as rod, bar, pipe.

In addition, the stacking member 23C is coupled to the upper surface of the upright member 23 and the upper support plate 23C1 to which the upper surface is tightly coupled to the bottom surface of the upper plate, and the upper surface of the upper support plate 23C1 is vertically coupled to the upper plate ( It consists of an upper socket (23C2) to be located in the post coupling hole (H) of 22) and a laminated rod (23C3) in which the lower outer peripheral surface is screwed to the inner circumferential surface of the upper socket (23C2).

In this case, the lower socket 23A2 and the upper socket 23C2 may protrude to the top surface of the bottom plate 21 and the top plate 22, respectively.

The outer circumferential surfaces of the stacking rods 23C3 and the upstanding member 23B are coupled to the inner circumferential surfaces of the upper and lower sockets 23C2 and 23A2, respectively, to the respective inner circumferential surfaces of the stacking rods 23C3 and the upright member 23B. The outer and upper surfaces of the upper and lower sockets 23C2 and 23A2 may be made to have opposite structures. In addition to screwing, there are various coupling structures, but screwing is preferable in terms of tightening force, coupling stability, and disassembly assembly.

In addition, the bottom surface of the stacking cap 23A3 of the connection member 23A should be positioned higher than the bottom surface of the wheel W coupled to the bottom surface of the bottom plate 21 so as not to contact the floor when the cart is moved. In order to prevent the wheels W of the upper cart from contacting the upper surface of the upper plate 22 of the lower cart, the length of the stacking rod 23C3 protruding from the upper surface of the upper plate 22 should be longer than the total height of the wheels W.

Shelf frame 24 is a rectangular frame provided in multiple stages directly above the bottom plate 21, hinges 24A are respectively coupled to the rear end outer surface side of each shelf frame 24, the hinge 24A It is connected to the outer peripheral surface of the pair of posts 23 on the rear side so as to be movable and detachable.

At this time, the hinge 24A is composed of a pair of hinge members 24A1 and 24A2 of which the other side is rotatable with respect to one side around the coupling part, and the one side hinge member 24A1 is coupled to the shelf frame 24. The other hinge member 24A2 is movable along the outer circumferential surface of the post 23 in a state where the other hinge member 24A2 is penetrated by the post 23, and the other hinge member 24A2 is stopped by a stop member S such as a pin or bolt. Temporary fixation is possible at any place on the outer circumferential surface of (23).

In the hinge 24A, the two hinge members 24A1 and 24A2 may overlap each other, but only 180 ° in the overlapped state, that is, the contact surfaces of the two hinge members 24A1 and 24A2 are one horizontal plane. It is desirable to be able to unfold as much as can be achieved by rotation, so that the front end of the shelf frame 24, whose rear end is coupled to the post 23 by the hinge 24A, does not fall directly below the horizontal plane. This is to allow rotation only above the horizontal plane.

In addition, the shelf frame 24 is for loading various parts, for example, an angle ("b") having a cross-section ("b") is made of an angle (angle), etc., but may also be coupled to the plate material therein, You don't have to just make an angle.

And, instead of the plate, the shelf frame 24 is installed in the pair of one or more bar-shaped rail member (24B) parallel to each other in the longitudinal direction of the shelf frame 24 and can adjust the space therebetween, It is also preferable to couple the plurality of partition members 24C movable and fixed along each rail member 24B to the rail member 24B.

At this time, if the partition member 24C may be long so that one bone may be simultaneously coupled with the plurality of rail members 24B, the partition member 24C may be short for each rail member 24B.

As described above, the structure in which the plurality of partition members 23C movable and fixed to the bar-shaped rail member 24B are coupled may also have various forms. For example, first, the inside of the rail member 24B may be used. Along the entire length, an open hollow H1 is formed.

Each of the partition members 24C is connected to a movable member 24C1 that can move along the inside of the hollow H1 of the rail member 24B, and a stop member S such as a bolt to the movable member 24C1, and the rails. The guide member 24C2 laminated on the outer surface of the member 24B can be configured to fix the position as the stop member S while the moving member 24C1 is moved to an appropriate position of the rail member 24B. By doing so, it is possible to appropriately adjust the interval between the guide members (24C2) to be the component storage space.

At this time, the movable member 24C1 may move along the rail member 24B, and may be coupled to the outer circumferential surface of the rail member 24B, and the guide member 24C2 may be moved with the movable member 24C1. It is possible to configure a variety of structures, such as one body, the stop member (S) may be coupled to the guide member (24C2) and the moving member (24C1) consisting of a body.

In addition, the upper and lower positions of each shelf frame 24 in which various parts are stacked can be adjusted, but it is inconvenient to adjust the position every time according to the size of the parts. While shaking, the parts stacked on the shelf frame 24 may also flow and surface scratches may occur.

Therefore, in order to solve the above problems, it is also preferable to provide each shelf frame 24 with a flow preventing member 24D capable of height adjustment within a predetermined range according to the size of the part.

For example, by connecting both vertical portions 24D1 of the upwardly open " c " shaped flow preventing member 24D to both ends in the longitudinal direction of the shelf frame 24 so as to separate and move up and down, respectively, The horizontal part 24D2 which connects the lower end part of the side vertical part 24D1 can be located directly under the bottom of the shelf frame 24 with which 24D was connected.

That is, as described above, the horizontal portion 24D2 of the flow preventing member 24D is positioned directly below the bottom of the shelf frame to which the 24D is coupled, so that the upper surface of the parts stacked on the shelf frame directly below may be pressed. Therefore, it is possible to prevent the flow of parts during the transfer, and according to the size of the parts by moving the vertical position (24D1) coupled to the shelf frame 24 in the vertical direction, by adjusting the horizontal portion ( The up and down positions of 24D2) can also be adjusted.

At this time, the structure of the flow preventing member (24D) to play such a role is also possible in a variety of forms, it is possible to prevent the flow of the parts accumulated in the shelf frame itself coupled to the flow preventing member (24D) rather than the shelf frame directly below. In such a case, it is inconvenient to tighten or loosen the flow preventing member 24D every time the part is loaded or withdrawn.

However, each shelf frame 24 constituting the cart of the present invention can be rotated only above the horizontal plane, so that the horizontal portion 24D2 of the flow preventing member 24D is positioned directly below the bottom of the shelf frame 24, This horizontal portion 24D2 by pressing the parts stacked on the immediately lower shelf frame, it is possible to prevent such inconvenience.

In other words, when loading a part into an arbitrary shelf frame, the front end of the upper shelf frame is lifted up, and after all the parts are stacked, the upper shelf frame is lowered to a horizontal state. The horizontal part of the combined flow preventing member automatically presses the parts stacked on the lower shelf frame, and when the upper shelf frame is lifted, the parts placed on the shelf frame can be withdrawn.

And when the front end part can be rotated directly on a horizontal plane centering around the hinge 24A, the shelf frame 24 will be horizontally maintained by the rigidity of the hinge 24A, and the hinge 24A will be given an unreasonable load and will hinge As the 24A is deformed or broken, the front end of the shelf frame 24 may be lowered directly below the horizontal plane.

Therefore, both ends of the bar-shaped support bar 25 constituting the left and right pairs, that is, the front and rear ends of the shelf frame 24, can be respectively supported so as to support the bottom faces of the left and right ends of the shelf frames 24, respectively. It is also preferable to penetrately couple to the outer circumferential surfaces of the front and rear posts facing each other so as to be in close contact with the bottom of 24.

In this case, when the support bar 25 is coupled to the shelf frame 24 separately, the inconvenience of having to adjust the position of the support bar 25 and the shelf frame 24 separately when the height of the shelf frame 24 is adjusted. With a bar, it is also preferable that the support bar 25 and the shelf frame 24 are integrally coupled to move together.

For example, the upper end surface of the rear end of the support bar 25 may be coupled to the bottom surface of the other hinge member 24A2 of the hinge 24A that is penetrated to the post 23.

The support bar 25 coupled to the other hinge member 24A2 by the coupling structure as described above is movable and fixed together with the shelf frame 24 and the hinge 24A coupled thereto when the shelf frame 24 moves. It does not interfere with the rotation of the shelf frame 24 coupled to one side hinge member 24A1 at all.

In addition, if necessary, through the method of joining the side wall plate between the bottom plate top edge and the bottom plate bottom edge, as shown in Figure 9, except for the front, rear, left, right or front of the cart. Both sides and the rear may be blocked with a sheet (B).

In addition, by turning the two ends of the support member 26 that can be contracted and expanded like a gas spring to the side of the shelf frame 24 and the support bar 25, respectively, the front of the shelf is lifted It is also preferable that the front part of the shelf frame 24 is not lowered by free fall in the state in which no force is applied to the frame 24.

And, as shown in Figure 10, a plurality of compartments in the rear two posts 23 located between the shelf frame 24, so that the plate can be mounted upright, such as LCD (LCD) or PD (PDF) panel, etc. By joining the rail member 24B to which the member 24C is coupled, the rear end of the standing plate can be positioned between two adjacent partition members 24C, so that the plate can be held in an upright position.

As described above, the component transport cart of the present invention, as well as freely adjust the stacking space secured in each of the plurality of shelf frames consisting of a multi-stage according to the size of the part, the advantage of easily preventing the flow of parts during transportation Thereby, there is an advantage that can prevent or minimize the scratch of the surface of the component generated during transportation of the component.
