Description

  The present invention relates to a car pallet for holding a car used for moving a load and transporting the car properly on a conveyor, and more particularly, a car that can hold the car stably and reliably in a state where the car is mounted. The present invention relates to a pallet for vehicle transportation.

  After manufacturing, cans, bottles, etc. filled with soft drinks, alcoholic beverages, etc. are packed together in a box or standing up in an open box for bottles. In general, the products are shipped, stored in a warehouse (delivery center), temporarily stored, sorted for each customer store, and delivered to each store. A delivery form is performed by a store as a car or a pallet as a support on which a load is placed.

  When the shipment form is a car, the load of beverages etc. is temporarily stored, then the various types of loads divided into load units such as boxes and open boxes are mixed and transferred by conveyor, and the loading device After one store corresponds to one pallet for delivery pallets and sorts the load for each store, the pallet loaded with the load for one store is further manually transferred to a car or by a loading device One store directly corresponds to one car and sorts the load of each store.

  In recent years, along with an increase in small-volume delivery opportunities to stores, there is an increasing need for a car as a shipping form, and therefore there is a strong demand for automation and time reduction of loading work on a car. However, in order to automate and efficiently load directly on the car or transfer from another pallet, the car is automatically desired without the help of the operator. It is necessary to carry in and out of the automation device at the timing.

However, since the car has wheels, there is a problem that it is difficult to transport the car with a transport device such as a conveyor as it is. For this reason, in order to smoothly transport such a car, a pallet that allows the car to be transported on the transport path has been proposed, and an example thereof is described in JP-A-9-328130. There is something that is.
JP 9-328130 A

  There are conventional pallets for transporting a car car as described in the above-mentioned patent document, and although a car loaded with a load can be appropriately transported by holding it without moving, a lock mechanism for fixing the car car on the pallet, In addition to having a complicated structure such as a stand for supporting it, there are many protrusions in the height direction, which makes it difficult to handle as a pallet, and has a problem that it is heavy and expensive.

  The present invention has been made to solve the above-mentioned problems, and can support a car with a simple structure and efficiently carry it by a carrying device such as a conveyor, thereby promoting the automation of car carriage at a lower cost. An object of the present invention is to provide a pallet for transporting a car.

The pallet for transporting a car according to the present invention is a pallet for transporting a car that is transported on a predetermined conveyor in an empty state or in a state where a plurality of wheels for transporting a load are placed at the bottom. , the upper surface is formed in a substantially trapezoidal-shaped body which is substantially rectangular planar shape, the upper surface, while being capable placing the squirrel car, the lower surface is transported rotatably supported in contact with the said conveyor A base portion and a guide surface at a position near the first edge of the upper surface of the base portion and substantially parallel to the edge and substantially perpendicular to the upper surface of the base portion, and the guide surface is one side of the car A wheel guide that can be slidably contacted with side surfaces of a plurality of wheels that are located closer to each other, and a guide for the wheel guide that is located near a second edge of the upper surface of the base portion that is substantially parallel to the first edge. The lower part of the side frame part of the other side part in the car that faces the surface and in which the wheel is in sliding contact with the guide surface A main body guide having another guide surface slidable on the surface, and a car that is erected along a third edge substantially perpendicular to each of the edges on the upper surface of the base portion. A substantially plate-shaped main body stopper portion that is capable of contacting the wheel and / or the side frame portion of the car to prevent the car from coming out of the base portion from the third edge, and the first on the base portion. A wheel stopper portion having a substantially plate shape and a rectangular cross section that is disposed substantially parallel to the edge at a position that forms a predetermined interval with the three edges and generates a step with respect to the upper surface of the base portion. A bar holding plate that partially surrounds the lower end portion of the car collapse prevention bar in a non-use state of the car car that is located outside the base part in the state of contact with the main body stopper part of the car car is attached to the outer surface of When the wheel or side frame of the car wheel is brought into contact with the main body stopper on the base, the main body stopper is offset.

  As shown in each of the drawings, a pallet 1 for transporting a car according to the present embodiment includes a base portion 2 formed of a substantially trapezoidal body whose upper surface is a substantially rectangular flat surface, and a first portion of the upper surface of the base portion 2. A wheel guide 3 disposed so as to be slidable in contact with the side surface of the wheel 13 of the car 10 at a position close to one edge 2a, and a second edge 2b parallel to the first edge 2a on the upper surface of the base 2 A main body guide 4 disposed so as to be slidable in contact with the lower side surface of the side frame portion 12 of the car wheel 10 at a side position, and a third edge 2 c perpendicular to the respective edges on the upper surface of the base portion 2. A substantially plate-shaped main body stopper portion 5 disposed in a standing state, and a substantially plate-shaped wheel stopper portion 6 disposed on the base portion 2 with a predetermined distance from the third edge 2c. It is the composition provided.

  In addition, the load carrying car 10 placed on the car transport pallet 1 according to the present embodiment has a flat load placing surface 11 and three sides excluding one side of the load placing surface 11. It has a substantially lattice-like side frame portion 12 arranged in a standing state upward, and four wheels 13 are arranged at the lowermost portion so as to be movable. The car 10 is loaded and placed in a fixed orientation with respect to the car carriage pallet 1 with the side part in an open state without the side frame part 12 being able to be loaded and unloaded. Thus, when the car 10 is transported by the conveyor 20 together with the car transporting pallet 1 and reaches the load transfer device (not shown), the opened side portion faces the load transfer device side and loads the load. It is a mechanism that can be placed.

  The base 2 is formed of a substantially trapezoidal body whose upper surface is a rectangular planar shape with a two-layer configuration of a thin plate wider than the car 10 and a small thick plate corresponding to the conveyor width. On the other hand, it can be placed on the upper surface of the shape, while the lower surface is brought into contact with the conveyor 20 for transport and is supported so as to be transportable. The car 10 is placed on the base 2 in such a direction that the open side of the car 10 is positioned on the first edge 2a side.

  The wheel guide 3 is formed of a narrow, substantially plate-like body standing on the base portion 2, and is substantially parallel to the edge 2a at a position near the first edge 2a on the upper surface of the base portion 2. The guide surface 3a is perpendicular to the upper surface of the base portion 2, and the guide surface 3a can be slidably contacted with a side surface below the rotation axis of the plurality of wheels 13 positioned near one side portion of the car wheel 10. It is the composition which is done. The end portion closer to the fourth edge 2d of the base portion 2 in the wheel guide 3 is bent in a direction away from the opposing main body guide 4. In addition, the wheel guide 3 is located near the side of the opened state of the car 10 with the car 10 placed on the base portion 2, but is lower than the loading surface 11. Therefore, there is no interference with the load placed on the car 10.

  The main body guide 4 is formed of a substantially plate-like body standing on the base portion 2, and is positioned closer to the second edge 2 b parallel to the first edge 2 a on the upper surface of the base portion 2. Another guide surface 4a that can be slidably contacted with the lower side surface of the side frame portion 12 of the other side portion of the car 10 facing the guide surface 3a of the wheel guide 3 and having the wheel 13 slidably contacted with the guide surface 3a. It is the structure which has. That is, the distance between the guide surfaces 3 a and 4 a is equal to the distance on the plane between the side surface of the wheel 13 of the car 10 and the outer surface of the side frame portion 12 on the side away from the wheel 13.

  The end near the fourth edge 2d of the base 2 in the main body guide 4 is also bent in a direction away from the opposing wheel guide 3, and the two guides 3 and 4 are respectively connected to each other. The car 10 is easily introduced onto the base portion 2 from the fourth edge 2d side by being bent away from each other and having a shape in which the distance between both guide end portions is increased toward the fourth edge 2d. is doing. Further, the main body guide 4 is in direct contact with the side frame portion 12 located on the side opposite to the opened side portion of the car car 10 when the car car 10 is placed on the base part 2. Even when a force for pushing the load into the car 10 is applied to the car 10 during loading, the car 10 can be supported from the rear side to prevent the car 10 from being displaced or tilted.

  The main body stopper portion 5 is formed of a plate-like body having a width substantially coincident with the base portion 2 and a height capable of contacting the lower portion of the side frame portion 12 of the car 10. It is the structure arrange | positioned in the standing state along the 3rd edge 2c which makes a right angle with an edge, and prevents the car 10 from going out of the base part 2 from the 3rd edge 2c side.

  On the outside of the main body stopper portion 5, there is a load collapse prevention bar 14 of the car 10 that is in contact with the main body stopper portion 5 and is in a holding state and is not used and is simply suspended. A bent plate-like bar holding plate 5a that is surrounded at a more outer position is attached, and the movable range of the load collapse prevention bar 14 in the state of holding the car 10 is narrowed to suppress unnecessary movement.

  The wheel stopper portion 6 is formed of a substantially plate-like body having a predetermined thickness, and is arranged in parallel with the edge 2c at a position that makes a predetermined distance from the third edge 2c on the base portion 2. When the side frame part 12 of the car 10 is brought into contact with the main body stopper part 5 on the base part 2, the corner portion is third with respect to each wheel 13 of the car car 10 located near the main body stopper part 5. In this state, the wheel 13 is in contact with the outer peripheral surface from the side opposite to the edge 2c.

  The thickness of the wheel stopper portion 6 is overridden by the movement of the car 10 by the wheel 13 on the base portion 2 when the inertia force is applied to the car 10 when the entire pallet is moved or stopped. When the worker pulls the car 10 from the pallet with a slight force, the thickness is set to an appropriate thickness so that the wheel 13 of the car 10 can get over. Thus, an operator can take out the car 10 quickly. Further, by providing a step as the wheel stopper portion 6, when the car 10 gets over the wheel stopper portion 6 and the wheel 13 lands on the upper surface of the base portion 2 in the operation of placing the car 10 on the base portion 2. A sound is generated from each part of the car 10 with the impact of the step. With this sound, the operator can easily recognize that the car 10 is locked, and the operation on the car 10 can be appropriately executed with the sound as a guide.

  The conveyor 20 for carrying and transporting the car pallet 1 for transporting the car according to the present embodiment is a known conveyor device that transports the car pallet 1 for carrying the car car 10 in an empty state or intermittently by a predetermined distance. Detailed description will be omitted. Among the conveyor 20, a plurality of locations such as a front portion of the load transfer device (not shown) serve as temporary stop positions of the car 10 in intermittent conveyance.

  Two predetermined locations that are temporary stop positions of the car 10 in the intermittent conveyance of the conveyor 20 are a carry-in part 21 and a carry-out part 22 of the car 10 with respect to the car car carry-in / out work place 30 provided adjacent to the conveyor 20, An operator loads and attaches the car 10 to and from the pallet 1 for transporting the car on the conveyor at the carry-in portion 21, and separates and removes the car 10 from the pallet 1 for transporting the car at the carry-out portion 22. I can do it.

  Next, the taking in and out of the car with respect to the car car transport pallet based on the above configuration will be described. As a premise, it is assumed that a number of pallets 1 for transporting a car are already placed on the conveyor 20 at a predetermined interval so as to be transported.

  In the carry-in part 21 of the conveyor 20, the empty car 10 is sequentially pushed from the car carrying-in / out work place 30 toward the car-carrying pallet 1 on the conveyor 20 in a stopped state, and the base part of the pallet. 2 is put on. The car 10 can be smoothly transferred to the base 2 from the car truck loading / unloading work place 30 whose height with the upper surface of the base 2 is substantially matched.

  The worker keeps pushing the car 10 that has entered the base portion 2 from the fourth edge 2d side, and the car 10 pushed by the operator rolls the wheel 13 against the upper surface of the base portion 2. Travel with it. At this time, the car 10 is guided by the wheel guide 3 and the main body guide 4 so that the car 10 can be moved straight on the base portion 2 toward the third edge 2c (FIG. 5, (See FIG. 6).

  Finally, the wheel 13 on the front side in the traveling direction reaches the wheel stopper portion 6 (see FIGS. 7 and 8), and the car 10 reaches the main body stopper portion 5 at the back end of the base portion 2 and gets in contact with it. (Refer to FIG. 10), the corner portion of the wheel stopper portion 6 is in contact with the outer peripheral surface of the wheel 13 from the fourth edge 2d side, and the wheel 13 is an obstacle to travel to the fourth edge 2d side. It will be necessary to get over the stopper portion 6, and the wheel 13 will not easily return to the fourth edge 2d side. Thus, the car 10 is held on the base portion 2. At this time, the cargo collapse prevention bar 14 of the car 10 is also surrounded by the bar holding plate 5a and is held along the side of the car 10 so that it does not fluctuate in each direction. There is no interference with various devices at the time of transportation, no trouble at the time of work by an operator, and the safety in handling the car 10 is increased.

  After the car 10 is held on the car transport pallet 1 in the carry-in section 21, the conveyor 20 resumes the transport operation, and the car 10 and the car transport pallet 1 are transported together on the conveyor 20. Go. In the car pallet 1 for transporting the car, by placing the car 10 attached with the wheel 13 on the base part 2 and appropriately holding it, adverse effects on the transport by the wheel 13 can be eliminated. And the guides 3 and 4 and the stoppers 5 and 6 can be transported appropriately without wobbling or rattling the entire car 10.

  When the car 10 and the car pallet 1 for transporting the car reach the front of the predetermined transfer device and stop once, the car 10 is loaded on the load mounting surface 11 by the transfer device. The The conveyor 20 is intermittently transported at intervals according to the loading / unloading of the car 10 with respect to the pallet and the transfer operation by the transfer device, and a series of operations are performed in the transfer device during the temporary stop period of the conveyor 20. The transfer operation is performed, and when the operation is completed, the conveyance of the conveyor 30 is resumed. As the transport is resumed, the car 10 and the car transport pallet 1 to which the load has been transferred are separated from the transfer device, while another car transport pallet 1 on which an empty car 10 is newly loaded is transferred. It reaches the front of the device and receives a load transfer operation.

  When the loaded car 10 and the car transporting pallet 1 reach the unloading unit 22 by transport by the conveyor 20, the car 10 is temporarily stopped, and the worker starts the unloading work on the car 10. As the operator pulls out, the car 10 moves and the wheel 13 rides on the wheel stopper 6 (see FIG. 9), and the wheel 13 completely gets over the wheel stopper 6 by further operation (see FIG. 8). ), The car 10 can run smoothly on the base 2. The worker draws the car 10 further and carries the car 10 from the base unit 2 to the car car loading / unloading work place 30 side. When the car 10 is completely transferred from the base 2 to the outside, the transporting operation of the conveyor 20 on which the car transporting pallet 1 is placed can be resumed.

  Thus, the car 10 removed from the car transport pallet 1 can travel in the car transporting / unloading work place 30 with the wheels 13, and shipping and delivery work for the store is separately performed by the worker. On the other hand, the car carriage pallet 1 from which the car 10 has been removed reaches the carry-in portion 21 again by the transfer by the conveyor 20, and it is repeated that the car 20 circulates with the new car 10.

  The worker places an empty car 10 on the car carriage pallet 1 stopped at the carry-in portion 21 and fixes it in the car carriage loading / unloading work place 30 and flows it to the conveyor 20, and the load is already loaded. The car car 10 in a state of being removed is taken out by the carry-out unit 22 and moved at the car car carry-in / out work place 30 and loaded on a truck or the like, so that the work efficiency is drastically improved.

  Thus, in the car pallet for carrying the car according to the present embodiment, the substantially plate-like wheel stopper 6 is arranged on the base 2 and the car 10 is guided by the two guides 3 and 4. When the car 10 is advanced toward the main body stopper 5 on the portion 2 and a part of the car 10 gets over the wheel stopper 6 on the base 2 and reaches the main body stopper 5, the rear of the wheel 13 of the car 10 is Since the wheel stopper portion 6 is in contact with the carriage 10 and hinders movement of the car 10 away from the main body stopper portion 5, the car 10 is placed on the base portion 2 and integrally held as a conveyor or the like. The car can be transported by the transport device, and the car 10 can be transported smoothly without any inconvenience caused by the wheels 13 of the car 10. On the base unit 2, when the car 10 gets over the wheel stopper 6 and reaches the main body stopper 5, the car 10 is locked to prevent the car 10 from returning in the reverse direction, and holds the car 10 during transportation. On the other hand, when the car 10 is taken out, if the operator pulls out the car 10 with a strong force, the car 10 can move over the wheel stopper portion 6 and move again on the base portion 2, and the car 10 can be moved when necessary. The mechanism for appropriately restraining the movement of the car can be realized in a simple manner, and a special locking mechanism for fixing the car 10 is not required, and the structure that can hold the car 10 appropriately can be significantly reduced in size and weight and cost. I can plan. At the same time, a special operation for fixing and releasing the car 10 is not required, and it is easy to handle and the work efficiency is greatly improved. In addition, mistakes such as forgetting the lock do not occur in the first place, and safety can be ensured.

  In the car pallet for carrying the car according to the above-described embodiment, the worker pulls the car 10 loaded with the load by himself / herself, gets over the wheel stopper 6 and takes it out of the base part. In addition, the pusher for extruding the stopped car 10 from the conveyor 20 to the car car loading / unloading work place 30 side is separately provided in the unloading part 22, and the predetermined position where the wheel 13 gets over the wheel stopper part 6. The car 10 can be pushed with a pusher to assist the take-out operation, so that the operator can easily move the car 10 and take it out, even when a heavy load is loaded on the car. The car 10 can be easily taken out over the wheel stopper portion 6.

  Moreover, in the car pallet for carrying the car according to the above-described embodiment, the wheel stopper portion 6 is fixed along the base portion 2, but the present invention is not limited thereto, and the wheel stopper is formed in a substantially plate shape. The part is movable with respect to the base part 2 and the wheel stopper part is lowered or rotated by a simple operation such as a stepping operation to shift to a state in which the wheel 13 does not become an obstacle, and the car 10 is locked to be movable. It is also possible to employ a configuration using a mechanism for releasing the state, and the take-out property of the car 10 can be greatly improved only with a slight unlocking operation.
