Description

  The present invention relates to a transportation device including a moving pallet in which a material to be transported on a moving pallet placed on a mounting table is loaded and unloaded by a forklift at a fixed position (loading work area) of the mounting table.

Conventionally, forklifts have been used in automated warehouses and department stores that handle a wide variety of products (conveyed items) when taking in and out large items to be transported. It is mounted on a loading platform or mounting table of a transport device such as a truck, a trailer, or a truck and is transported to a predetermined place.
In this case, when loading and unloading work (loading work) with a forklift from a loading platform or mounting table of transport equipment moved to a predetermined location, the lower surface of the transported material is supported by the fork. A gap for inserting the fork is required between the object to be transported and the mounting table.

For this reason, conventionally, a concave portion of a certain height for inserting a fork is formed in the center of the mounting table of the transport equipment, or a load handling work of a transported object is performed on the mounting table using a dedicated pallet into which the fork can be inserted. It has been broken.
In the former case, the structure is such that a recess is formed in the center of the mounting table, which has the problem that the structure of the transportation equipment is complicated and expensive, and in the latter case, a plurality of dedicated pallets are required. Since it is necessary to provide a separate storage place for pooling, there is a problem that it takes time and labor for cargo handling work.

  As a cart (transport equipment) that solves these problems, a concave part with a simple structure is formed in the center of the mounting table on which the object is placed, and a fork can be inserted into the lower surface of the object from the side of the carriage. A cart with a gap has been proposed (see Patent Document 1).

JP 2010-12847 A

By the way, the cart disclosed in Patent Document 1 conveys a single object to be conveyed, and in order to convey a plurality of objects to be conveyed, it is only necessary to widen the loading area. Once formed, there is a restriction on the length of the fork in order to take out the object to be transported placed in the back of the mounting table.
For this reason, it is possible to carry out cargo handling work with a fork from the lateral side of the carriage by placing the carriage in a narrow vertically long structure and placing a plurality of objects to be carried in a row on the placing table. There is a restriction on the cargo handling work from the side due to the necessity of parking the trolleys in parallel and the relationship between the factory building structure and the arrangement of the machines.

Therefore, there is a need for a transport device that can carry the cargo handling work from a fixed position using a fork. However, if the transport device is a carriage, there is a towing vehicle in front, so only from the rear end side. Cargo handling work will be performed.
Therefore, in a conventional carriage (transport equipment), a movable pallet that can move forward and backward in the direction of travel is placed on the mounting table, and the moving pallet at the back (front end) of the mounting table is from the rear end side. A passenger who got off the forklift to manually carry out the cargo handling work manually moved the movable pallet to the cargo handling area on the rear end side.

Therefore, in the conventional cart (transportation equipment), the forklift occupant himself / herself moves the moving pallet to the rear at the time of the cargo handling work, and therefore, there is an inconvenience that it is necessary to repeatedly get on and off the forklift every time.
For these reasons, there has been a demand for a transport device that can move the moving pallet on the mounting table to the rear end side (loading work area) while the forklift passenger is still on board.

  In view of the problems of the prior art, the present invention is intended to quickly and smoothly carry a cargo to be transported by moving a moving pallet to a cargo handling work area of a mounting table by a fork operation of a forklift passenger. With the goal.

In order to solve the above-mentioned problem, a transportation device provided with a moving pallet according to the present invention is:
A loading table configured to be able to load a material to be transported by a forklift, and a loading / unloading work area in which the material to be transported on the mounting table can be loaded and unloaded by a forklift supported by a track disposed on the mounting table. And a movable pallet that can be moved outside the loading / unloading work area, and the loaded pallet can be loaded on the loading / unloading work area of the mounting table when the moving pallet is outside the loading / unloading work area. In the equipment,
Movable means provided in the vicinity of the loading / unloading work area of the mounting table and moving downward by a pressing load applied by a fork of the forklift; and moving the movable pallet on the track in conjunction with the vertical movement of the movable means And converting means for converting to a moving means, and balancing means for maintaining the movable pallet at that position by maintaining a balance with the weight of the movable means when the pressing load of the movable means is released. And

According to this invention, the forklift occupant can move the moving pallet on which the object to be transported is moved to the cargo handling work area by pressing the fork while the forklift is on the forklift. Thereby, the movement operation of the moving pallet by the passenger can be omitted. As a result, the cargo handling work time can be shortened.
In addition, since the balancing means balances the weight of the movable means, even when the pressing load on the movable means is in an unloaded state, the movement of the moving pallet that is linked to the weight of the movable means is prevented. can do.

In the present invention, it is preferable that the movable means includes a movable pulley, a support frame is provided in the vicinity of the loading / unloading work area of the mounting table, and the support frame winds and supports the movable pulley. And a pair of fixed pulleys are rotatably supported to change the direction of the traction means wound up around the movable pulley and guide the moving pallet horizontally forward. The other end is connected to the moving pallet.
According to such a configuration, since the movable means is provided with the movable pulley, the backward movement amount of the moving pallet can be obtained as twice as much as the pressing movement amount of the movable means.

Preferably, in the present invention, a locking means for engaging and holding the moved movable pallet outside the loading / unloading work area is provided outside the loading / unloading work area of the mounting table, and the locking means is provided below the moving pallet. A locking claw that is pivotally supported so that the rear end side can be slid up and down to elastically engage with a jaw portion provided on the top surface of the front end side by the biasing force of the spring member with respect to the hanging locking member; It is characterized by comprising locking means for locking and unlocking the engaged state with the member, and a swing operation lever for performing locking and unlocking operation of the locking means.
According to this configuration, the locking pallet that engages and holds the movable pallet at a fixed position is provided outside the loading / unloading work area of the mounting table. The locking claw is pushed down against the urging force of the spring member by the action of the inclined surface by the locking member, and is engaged with the jaw portion on the tip side to maintain the stopped state.
Further, since the locking means is provided with a locking means, when the transportation device is a cart, the locking device is locked with the locking member of the moving pallet by the operation of the peristaltic operation lever by the operation of the tow vehicle passenger who pulls the cart. The engagement state with the claw can be locked, and even when the transport device is a truck, the truck driver can operate the peristaltic operation lever.

In the present invention, it is preferable that the movable means is a horizontally long movable means that can contact a pair of forks, and the movable means is configured to be guided up and down by a pair of suspended guide means. It is characterized by that.
According to such a configuration, when the pressing load is applied to the movable means by the pair of forks, the movable means can be smoothly moved downward by the pair of guide means even if the pressing load acts unevenly from side to side. Can do.

In the present invention, it is preferable that at least two movable pallets and a fixed pallet are adjacent to each other, and when the movable pallet is outside the cargo handling work area, two stationary pallets are fixed to the loading work work area. A mounting portion for mounting the pallet adjacent in the width direction is formed.
According to this configuration, when two moving pallets are outside the loading / unloading work area of the mounting table, the fixed pallet mounting table is formed so that two fixed pallets are mounted on the loading / unloading work area of the mounting table. Therefore, the load capacity of the moving pallet can be increased.

As described above, according to the transportation equipment having the moving pallet of the present invention, when the work to be loaded and unloaded on the moving pallet is performed, the fork lift operation is performed while the passenger is still on the forklift. The moving pallet outside the cargo handling work area can be moved to the cargo handling work area in conjunction with the moving means that moves downward. As a result, the moving work of the moving pallet by the rider can be omitted. As a result, the rider of the forklift does not need to get on and off the forklift, can reduce fatigue, and can shorten the cargo handling work time.
In addition, since the transportation device is provided with a balancing means, the balancing means balances the weight of the movable means even when the pressing load on the movable means is in an unloaded state. It is possible to prevent the backward movement of the moving pallet that is self-propelled in conjunction with the.

In addition, since a movable pulley is provided at the center of the movable means, the moving amount of the moving pallet that moves backward in conjunction with the downward movement of the movable means is double the backward movement of the movable means. The quantity can be obtained.
Accordingly, the placement position of the transported object on the transport device can be lowered, so that the transported object can be prevented from becoming unstable during movement, and the transported object can be prevented from being damaged and can be safely operated.

In addition, since the mounting table is provided with a locking means, the moving pallet moved outside the loading work area of the mounting table resists the biasing force of the spring member by the locking member by the action of the inclined surface by the locking member. And is held down by being engaged with the front jaw.
Further, since the locking means is provided with a locking means, when the transportation device is a carriage, the engagement means is engaged with the locking member of the movable pallet by the operation of the peristaltic operation lever by the operation of the tow vehicle passenger who pulls the carriage. The engagement state with the pawl can be locked. Thereby, even if a vibration occurs during the transportation of the transported object, the movement of the moving pallet is restricted, so that the transported object can be transported safely.

  Since the movable means is guided up and down by a pair of guide means suspended from the vicinity of the cargo handling work area of the mounting table, the movable means can be moved by the pair of guide means even if the pressing load by the fork acts unevenly on the left and right. The means can be moved down smoothly.

  The mounting table of the transport equipment has a structure in which at least two moving pallets are movably mounted in parallel. When the two moving pallets are outside the loading work area of the mounting table, the loading work area Since this mounting table is formed as a fixed pallet mounting table on which two fixed pallets are mounted, the loading amount of the movable pallet can be doubled.

FIG. 3 is a side view of the carriage showing a partial cross section in which the movable pallet moved to the front end position is in an engaged state, and FIG. 4 is one side of the carriage with respect to the center line in the lateral width of the carriage having a symmetrical structure. It is a top view of the trolley | bogie which shows.

1 to 4, reference numeral 1 denotes a carriage for carrying the article W to be carried on the moving pallets 40, 42, and the carriage 1 is formed by joining square bars vertically and horizontally by welding or the like to form a rectangular plane as a whole. It is formed as a frame having a lattice shape, and a mounting table 2 is provided on the upper surface of the frame.
A pair of wheels (a universal caster 4 and a fixed caster 5) are respectively attached to the lower surface of the carriage 1 in the front-rear direction, and a connecting tool 13 for pulling the carriage 1 is not shown in front of the carriage 1. It is connected to the towing vehicle.

A pair of rails 6 and 7 constituting a track are mounted on the mounting table 2 of the carriage 1 in parallel in the traveling direction on the left and right sides in the width direction. Two moving pallets 40 and 42 are supported on the rails 6 and 7 through four wheels 45 so as to be movable back and forth.
The moving pallets 40 and 42 are formed as a frame that forms a rectangular grid by joining square bars by welding or the like in the vertical and horizontal directions as in the case of the carriage 1, and the upper surface thereof is a transported object such as a gasoline or diesel engine ( Work support portions 8, 9 and 10, 11 are disposed at the front and rear end portions and the width direction left and right end portions in order to mount the workpiece W in a stable state.

  As shown in FIG. 4, a fixed pallet mounting table 3 for mounting two fixed pallets 43 (see FIG. 2) adjacent to the right and left is formed behind the mounting table 2 on the carriage 1. The pallet placing table 3 is used as an area for placing the fixed pallet 43 when the two moving pallets 40 and 42 are on the front side (outside the cargo handling work area) of the placing table 2.

  With this configuration, when the two moving pallets 40 and 42 are on the front side of the mounting table 2, the fixed pallet mounting table 3 on which the two fixed pallets 43 are mounted behind the mounting table 2. Therefore, the pallet load can be doubled.

(Movable means)
On the other hand, as shown in FIG. 3, guide means (a pair of guide rails 16a and 16b) are vertically supported on both sides of the rear end of the carriage 1 in the traveling direction. A movable means (pressing table 15) for moving the pallets 40, 42 back and forth is guided and supported so as to be movable up and down.
The pressing table 15 is configured to be horizontally long by joining two plate members in an L-shaped cross section, and the horizontal surface of the plate member is a pressing portion for applying a pressing load by a pair of forks F, A movable pulley 18 is rotatably supported at the center in the width direction of the horizontal plane.

On the other hand, a support frame 14 made of two plates is erected on the rear end side in the traveling direction of the carriage 1 in a state of being offset backward, and a traction means (chain 12) is provided at the rear end of the support frame 14. ) One end is fixed.
A moving pulley 18 of the pressing table 15 corresponds directly below the support frame 14, and a chain 12 that is fixed to the rear end of the support frame 14 and hangs downward is wound around the moving pulley 18. Has been.
The chain 12 extending vertically upward from the movable pulley 18 is wound around a first fixed pulley 20 pivotally supported at the rear of the support frame 14, and then second fixedly supported adjacent to the fixed pulley 20. The direction is changed in the horizontal direction via the pulley 21 and extends forward.

  In this way, the horizontally long pressing table 15 moves up and down as both ends are guided by the pair of guide rails 16a and 16b when the pressing load is applied by the pair of forks F. Even if they act unevenly from side to side, the pressing table 15 can be moved downward smoothly.

(Moving palette)
In the two moving pallets 40 and 42, a rod-like chain support 22 protrudes vertically downward from a substantially central lower surface, and the other end of the chain 12 is fixed to the lower end of the chain support 22. .
Similarly, a suspending band support 23 protrudes vertically below the substantially central lower surface of the two moving pallets 40 and 42 so as to be adjacent to the chain support 22. At the lower end, an end of a suspension band 25 that is pulled out against a biasing force from a balance means (known balancer 24) disposed on the rear end side of the carriage 2 is secured.

In this way, the weight of the pressing table 15 is given to the rear side of the two moving pallets 40 and 42 by the chain 12 via the movable pulley 18, and the balancer 24 is arranged on the front side of the moving pallets 40 and 42. The pulling back drag of the suspension band 25 is acting.
As a result, the balancer 24 balances the movement load of the moving pallets 40, 42 acting backward due to the weight of the pressing table 15 and the drag of the suspension band 25 pulled out against the biasing force from the balancer 24. Is set to

Therefore, since the movable pallets 40 and 42 can prevent the backward movement of the movable pallets 40 and 42 that are self-propelled in conjunction with the weight of the pressing table 15, the pressing load on the pressing table 15 becomes an unloaded state. Even in the case of a failure, it can be stopped at an arbitrary position.
When a pressing load is applied by a pair of forks F to a horizontal plane that is a pressing portion of the pressing table 15, the moving pallets 40 and 42 are moved behind the carriage 1 in conjunction with the downward movement of the pressing table 15. You can move towards.

In this case, since a part of the chain 12 connected to the movable pallets 40 and 42 is wound around the movable pulley 18, the backward movement amount of the movable pallets 40 and 42 becomes the downward movement amount of the pressing table 15. On the other hand, a movement amount twice as large can be obtained.
As described above, the fork F can be moved to the cargo handling work area at the rear end of the carriage 1 by pushing down the fork F while the forklift passenger is in the state of being on the forklift. it can. As a result, the work of the passenger getting off the forklift and moving the moving pallets 40, 42 can be omitted. As a result, the cargo handling work time can be shortened. As a result, the cargo handling work time can be shortened and the passenger's fatigue can be further reduced.
