Description

Loading and transporting pallets and loading individual pallets {Separate supplying device for pallette}

The present invention relates to a pallet transporting and supplying apparatus in a manufacturing facility for producing a Jeonju root price for use in dry construction, and more particularly, the pallet loaded in multiple stages is sequentially discharged from the bottom to form a Jeonju root price By individually supplying to the molding apparatus for, it is reasonably overcome the problems of the conventional pallet supply step that was dependent on the individual manual work.

In general, during the construction of a dry pole that is intended to install poles, the poles of Jeonju, which prevents the poles from tilting or falling vertically, are usually buried in the ground. Later, the excavation point is buried in the vicinity of the Jeonju to choose the way to connect with the Jeonju through the branch line.

The pole pole price is typically a rectangular pole pole price of a rectangular block, the rectangular pole pole price is buried in the excavation site in the transverse direction with respect to the pole pole, the pole pole pole and branch line rod is maintained at a right angle to the pole pole Fastening is the ideal construction method.

However, in the case of the rectangular Jeonju working price as described above, excessive labor costs and prolonged construction time caused by manpower construction, and the construction work and weakening the buried bearing capacity of the labor price due to mechanized excavation is pointed out as a problem. Likewise, in order to bury the square pole price, it is difficult to carry out excavation work for many parts.

Accordingly, the applicant of the present invention proposes a circular pole weight as shown in Patent Registration No. 0738279, a semi-circular pole weight as in Patent Registration No. 0755903, and an arch pole pole price as in Patent Registration No. 0772919, respectively. Tried to reasonably overcome all the problems he had.

Jeonju root having various shapes and structures as described above is usually produced by undergoing a sufficient curing process for the molding after continuously molding by pressing the sand gravel, stone powder and cement with water and stirring continuously from a separate molding mold .

That is, after mixing and stirring sand gravel, stone powder, cement, and water well, such mortar is introduced into a mortar injector, and the mortar injector is reciprocated several times along the mold to inject mortar into the mold. The mold is injected in the state that the vibration is imparted to discharge the air in the mortar and at the same time to compact the mortar so that the mortar is produced primarily along the shape of the mold.

The molded article in such a state is separated and removed from the mold, and then the molded article is placed on a separate pallet, and then the pallet is transferred to a curing chamber so that the wet steaming curing of the molded article is performed by high temperature steam. It is possible to produce a labor price.

In more detail, in the state of producing the first mortar by mixing sand gravel and stone powder, and cement and water in an appropriate ratio, the above mortar is introduced into the mold. At the same time, when the pellets in the flat form are individually injected from the outside of the mold, and the molding is completed in the mold through the mortar injection device, the pallet in the flat form is moved to the upper side of the mold.

That is, the molding die will have a groove-shaped molded part with an open upper part according to the shape of the muscle, and the pallet will be inverted in a state in which the molded part by mortar is press-molded, that is, flat The pallet is turned upside down so that the top surface faces the mold. In this case, a separate pallet supply rotating device installed at a position spaced apart from the forming frame is used, and the pallet supplied so that the flat surface faces upward is inputted toward the forming frame in an inverted state through the supply rotating device. Will be.

In addition, the pallet in the inverted state as described above is clamped to each other so that the flat surface is in close contact with the upper surface of the mold, to turn the mold and the pallet at the same time so that the moldings in the mold to naturally exit the upper surface of the pallet. will be. In this state, the pallet is separated from the lower part of the molding die, and then the pallet and the molding are moved to a curing chamber so that curing of the molding is performed. In addition, after the curing of the molding is made by the worker to separate the pallet and the pole price and convey only the pure pallet back to the rotary feeder to produce a continuous pole price production.

Accordingly, the raw material input unit for the above-mentioned stone powder and sand gravel and cement and water, the mortar mixing unit by mixing the input raw materials, the mortar supply unit, the pallet supply rotating unit, the forming unit and the rotating unit for the pallet, and having a molding It can be said that it consists of a pallet transporting unit, a molding curing unit, a pallet and a pole pole price separating unit, and a pole pole family production facility formed by re-inserting the separated pallet.

However, the above-mentioned Jeonju near-counter manufacturing facilities are provided with raw materials consisting of stone powder, sand gravel and cement and water, and the mortar generating unit made by stirring them according to a predetermined mixing amount is separately or separately installed from the molding apparatus. It is inconvenient for the supply and demand of mortar because the produced mortar must be transported to a production facility by a separate transportation means (for example, a mixer truck or a general transport truck) and then fed to a mortar injection device located on one side of the molding frame. Of course, in mixing and mixing the mortar, there is an uneconomic problem that requires a separate production and operator and facility manager.

In addition, since the pallets for supporting and curing the moldings discharged from the mold are individually inputted and supplied by using a forklift, the forklift continuously reciprocates, and only one pallet is continuously input, so the production facility is very crowded and various. It is exposed to safety accidents. Likewise, the molded product and the pallet discharged from the molding mold also have to be transferred from the molding apparatus to the curing chamber using a forklift, etc., thus holding the problem in the supplying step as described above.

In particular, the production and supply of mortar as described above is very delayed because the production and supply of mortar and the input and separation of pallets and the curing and separation and transportation of the price of Jeonju are all dependent on the manual work by means of transportation and manpower such as forklifts. As a result, excessive increase in production costs for working prices is achieved, and there are many difficulties in producing uniform and diverse working prices, and because a large number of vehicles, forklifts, or workers are required, congestion and workplace are required with excessive labor costs. It is a problem that is exposed to extreme noise and various safety accidents in the inside.

Accordingly, the applicant of the present invention, as shown in 2009 Patent Application No. 089963 and FIG. 1, the horn and sand gravel and sand transported and measured from the storage hopper 110 together with the cement and water through the stirring device 120 , The mixed mortar is automatically injected into the mortar injection device 130 located on the upper side of the molding die 140 near the electric pole, and pressurizing the mortar in the molding die 140 on the lower side of the molding die 140. Pushing device 150 is positioned, the pallet having the molded article pressed by the molding die 130 and discharged to the other side of the lower mold to be automatically transported to the curing chamber 160 in the loading state, the curing Pallets including the pole price discharged from the seal is separated into the pole price and the pallet by the separating device 170, so that the separated pole price is shipped and the separated pallet is re-introduced to the bottom of the molding frame Bar suggested that the automated production facilities of the pole geunga by gender,

According to the above-described automated production equipment, the production and input of mortar for molding the pole price and the molding of the pole price by the mortar, as well as the automatic loading of the pallet to support the pole price and the discharge and loading and transportation of the pallet having the molded product. Although it is automatic, curing and separation of moldings and re-entry of empty pallets are all performed by an automated process, which greatly increases the production speed of electric pole prices and is very economical, and greatly reduces the number of workers or managers. This is an excellent reduction of the cost, and since the whole process is made organically by automation, it can be seen that the prevention of safety accidents has an excellent effect.

Here, the molded product of the vicinity of the electric pole discharged from the molding die 130 is put on a pallet in a wide flat form is transported to the curing room with the pallet is subjected to a long curing process, the pallet is a separate supply device Through the mold 130 is to be supplied separately.

However, such a pallet is a heavy body that is usually by bending and welding a metal material, so that each one of the pallets is sequentially supplied by using a forklift, etc., so that the pallet contains many problems in the supply process. .

In other words, the pallet has a high weight as described above, rather than being transported by an operator, the pallet is transported individually using a heavy machine such as a forklift, and is individually supplied to a mold through a separate input device. Accordingly, since one worker and one forklift have to continuously perform repetitive work to continuously supply pallets, the worker cannot rest or stop the operation of the forklift in the production process near Jeonju. Therefore, when the worker has to stop the operation to take a break or to maintain or check the forklift, it is unavoidable to stop the entire production line, which causes a great drop in productivity.

In addition, the pallet is to have a cycle of repetition to be separated from the jeonju root value after the curing process and re-inserted it into the molding frame, the forklift is repeatedly operated between the jeonju muscle separation device and the molding frame Since individual supply of pallets must be continued, there is always instability of supply and demand for pallets.

In particular, as the forklift truck is repeatedly operated as described above, as pallets are not supplied quickly, it is pointed out as a cause of lowering the production speed for the entire weekly price as the overall pallet is not input. I have a problem.

The present invention is to solve the problems as described above, the pallet provided in a multi-stacked state is carried through the moving vehicle having a lifting plate to the loading stand, and the lifting platform embedded in the bottom of the loading stand is from the loading stand The individual pallet is separated and taken out from the lower side, and the supply truck located on the other side of the loading stand is provided with the pallet from the platform to be supplied to the molding apparatus,

By loading and transporting a large amount of pallets at once, and separating individual pallets sequentially from the bottom of these stacked pallets and feeding them to the molding apparatus, various problems in the conventional pallet supply process can be solved at one time. It is an object of the present invention to provide for the transport and transportation of pallets and for the individual supply of stacked pallets.

The present invention for achieving the object as described above, respectively comprising a rail installed side by side toward the forming apparatus for molding the electric pole root and a moving car and a supply vehicle that flows along the rail, the middle portion of the rail Install the storage racks, and form a platform between the rails are installed,

Loaded pallets carried to the end of the rail are placed on the loading stand via the moving car, and a single pallet located at the lowermost side through the platform is removed from the loading stand and the pallet is placed on the upper part of the supply truck. It is configured to be configured to be transported to the molding machine is supplied to the pallet provided on the pallet.

According to the present invention, a large amount of pallets are loaded and transported at a time, and the individual pallets are separated and automatically supplied sequentially from the bottom of the pallets in the stacked state, so that the supply of the pallets is smooth and the shortening of the supply time is simplified. It is possible to increase the productivity of the electric pole price as a whole, and to carry a large amount of pallets at a time to be individually supplied, significantly reducing the number of round trips of the forklift, such as to prevent safety accidents and greatly improve the work efficiency.

Accordingly, the pallets 60 and 60 'carried in the loaded state through the forklift are lowered to the ends of the rails 10 and 10', and the pallets 60 and 60 'are in this state. When lifted up through the moving car 20 and placed on the loading rack 40, the pallet 60, which is located at the lowermost side through the lifting platform 50, is sequentially separated out from the loading rack 40 and the supply vehicle Placed on the 30, the supply vehicle 30 is moved to supply the pallet 60 to the molding apparatus 70.

As shown in FIG. 3, the moving vehicle 20 includes a main body 21 having a planar quadrangular shape, and the driving motor 22 fixed to the main body 21 is rotatably mounted from a lower part of the main body. When the driving motor 22 is operated so that power is transmitted to the moving roller 23, the moving roller 23 rotates while the moving vehicle 20 reciprocates along the rails 10 and 10 '. On the upper side of the main body 21, a lifting plate 25 in the form of a plate is installed so that the lifting plate 25 is moved upward and downward through the actuator 24 mounted to the main body 21. It was to be lifted.

As shown in FIG. 4, the supply vehicle 30 includes a frame body 31 of which one side is opened, and the motor 31 is mounted on the frame body 31 of the frame motor 31. The driving force is transmitted to the driving roller 33 rotatably mounted on both sides of the lower part of the frame 31. When the electric motor 32 is operated, the above-mentioned supply vehicle is rotated by the rotation of the driving roller 33. 30 may be reciprocated along the rails 10, 10 ′.

As shown in FIG. 5, the loading stand 40 includes a pair of supports 41 and 41 ′ which are installed to face each other on the outside of the rails 10 and 10 ′. In (41) (41 '), the anchor pins (42) and (42'), which emerge from each other toward the opposite sides, are inserted apart from each other. 'Is connected to each other by a drive plate 44 located on the opposite rear side of the'), and the drive plate 44 is caused to flow by the cylinder 43 coupled to the supports 41, 41 '. The cylinder 43 of the serves to allow the pinch 42, 42 'to be set out in the opposite direction.

As shown in FIG. 6, the lifting platform 50 is installed between the rails 10 and 10 ′ in which the mounting base 40 is installed. The exposed base and the power base 52 for elevating the base plate 51 are embedded in the ground, and the platform 50 includes the rail car 10 and the moving car 20 and the supply car 30. In the process of reciprocating along the 10 ', the buried installation structure is exposed to the upper surface of the base plate 51 so that the interference between the vehicle 20 and the supply vehicle 30 does not occur. Here, the power base 52 is a rack gear and a pinion gear combination of the gear box combined by the connecting shaft to rotate the pinion gear as a plurality of vertically formed rack gears in the vertical direction at the same time, It is intended to be lifted and is generally applied to lift devices.

Accordingly, a detailed operation of the pallet supply unit of the present invention having the above configuration will be described.

The pallets 60 and 60 'have a shape in which a plurality of support angles are coupled to a lower portion of the flat plate as in a flat shape, and the upper surface of the molded product near the electric pole discharged from the forming apparatus 70 is formed on the upper surface. It is a supporting member for transferring the dent to the curing room to obtain a firmly cured pole weight. After separating the finished pole weight from the pallets 60, 60 ', empty pallets 60, 60'. Since it is to be supplied to the molding apparatus 70 again, the pallets 60 and 60 'are continuously used.

The pallets 60 and 60 'which are used in such a circulation are separated from the electric poles of the electric poles as described above, and the pallets are stacked on at least six steps above by using a forklift or the like. It will be transported at once and put down on the ends of the rails 10 and 10 '. At this time, the rail end portion may be provided with a support higher than the height of the rail.

In this state, the mobile vehicle 20 moves below the pallets 60 and 60 'in the loaded state, and the lifting plate 25 of the mobile vehicle 20 is raised to raise the pallets 60 and 60'. In the lifted state, the pallets 60 and 60 'are transported between the loading racks 40 as shown in FIG. Subsequently, as shown in FIG. 9, the elevating plate 25 of the vehicle 20 is further raised through the actuator 24 so that the lowermost pallet 60 is placed on the anchor pins 42 and 42 of the loading table 40. ') Is to move up to position above.

When the pallets 60 and 60 'are sufficiently raised as described above, as shown in FIG. 10, the anchor pins 42 and 42' of the loading stand 40 protrude from each other through the operation of the cylinder 43. As the protruding ends of the anchor pins 42 and 42 'are protruded to the inner side of the pallets 60 and 60', the elevating plate 25 of the moving vehicle 20 is lowered. When the pallet 60, 60 'is placed on the pinch 42, 42' is not lowered and the lifting plate 25 is separated from the pallet (60) (60 ') pallet ( It is possible to return to the ends of the rails 10 and 10 ', which are the first positions for carrying 60 and 60'.

In this state, the supply vehicle 30, which is another transportation means reciprocating along the rails 10 and 10 ′, moves under the pallets 60 and 60 ′ in the stacked state as shown in FIG. 11. Subsequently, the mounting plate 51 of the platform 50 in the underground state as shown in FIG. 12 is powered by the power base 52, and the supply car 30 has one side open. It has the form of "C" and the mounting plate 51 has a width and width enough to freely move up and down through the open space of the inside of the supply vehicle 30, the supply vehicle 30 of the pallet In the state below 60 (60) (60 '), the base plate 51 of the platform 50 can rise without any interference.

In addition, as the mounting plate 51 is raised, the pallets 60 and 60 'in the stacked state, which are placed on the mounting pins 42 and 42' of the loading stand 40, are raised at the same time. When the entire pallet 60, 60 ′ rises, the anchor pins 42, 42 ′ are recessed by operating in opposite directions through the operation of the cylinder 43. Therefore, when the base pins 42 and 42 'are recessed, the base plate 51 in a raised state starts to descend, and the upper surface of the lowermost pallet 60 is lowered as the base plate 51 descends. When passing through the lower part of the settling pins 42 and 42 ', the settling plates 42 and 42' in the recessed state protrude again by the cylinder 43, except for the lowermost pallet 60 as shown in FIG. The remaining pallets 60 'are to be placed on the anchor pins 42 and 42'.

Accordingly, the mounting plate 51 of the platform 50 is continuously lowered so that the pallet 60 in the separated state is placed on the upper portion of the supply vehicle 30 in the advanced state. Subsequently, the supply vehicle 30 moves along the rails 10 and 10 'through the operation of the electric motor 32 to separately supply the pallet 60 as described above to the molding apparatus 70. Accordingly, the molding apparatus 70 for the pallets 60 and 60 'is sequentially drawn out from the plurality of pallets 60 and 60' that are supplied in a stacked state. Furnace supply can be made smoothly and quickly.

Such a pallet supply apparatus of the present invention may be applied in the step for supplying the empty pallet to the molding apparatus as described above, as shown in FIG. When it is discharged from the curing room in a state where it is mounted on the 60, 60 ', the pallets 60 and 60' of the loaded state as described above are also moved to the vehicle 20, the supply vehicle 30, and the loading rack 40 and the platform. Through the configuration of 50 may be separately supplied to the separation device for separating the pallet 60, 60 'and the pole price 80.

In particular, the vehicle 20 in the above-described embodiment has an actuator for placing the pallets 60, 60 'in the state of being stacked on the anchor pins 42, 42' of the loading table 40. It requires a fairly long stroke of (24), the longer the stroke of the actuator 24 will increase the instability in the conveying process of the pallets 60, 60 ', and the relatively low height of the vehicle ( Since there will be considerable technical difficulties in mounting the actuator 24 having an excessive stroke in 20), in such a case, the mounting pins 42 and 42 'of the mounting base 40 are raised as shown in FIG. It is possible to solve this by forming a divided space.

That is, the pallet 60, 60 'of the loaded state is transported to the loading base 40 through the moving vehicle 20 having a short lifting stroke, and then placed on the anchor pin 42 positioned below. 20) After placing the pallets 60 and 60 'loaded using their own short strokes, when the moving vehicle 20 exits, the underground platform 50 is raised to lower the upper base pin 42. The pallets 60 and 60 'positioned at the upper side are further lifted so as to be placed on the anchor pin 43' located at the upper side, thereby improving the transport stability for the vehicle 20 and at the same time, the design can be facilitated. To ensure that

Accordingly, the pallet transporting and supplying apparatus of the present invention can supply a plurality of pallets at the same time and sequentially separate only one pallet from them to be supplied to a molding apparatus or to a neighboring separator so that the pallets can be transported and supplied. Various problems and inefficiencies can be solved at once.
