The present invention also provides delivery of the transported object between the supply shelf for delivering the transported object and the shelves, and delivery of the transported object between the shelves and the demand shelf. An article transfer system realized by an operation of simply pressing, an operation of pressing a shelves on a demand shelf, and an action in which a fluidized sliding support material moves an object to be conveyed by gravity, and shelves and shelves constituting the article transfer system It belongs to the technical field of carts.

Conventionally, a method for transporting materials and parts necessary for product assembly at a relatively short distance, for example, in a product assembly factory, that is, transporting necessary materials and parts from a storage shelf to the assembly site. In this method, the transporter takes out the necessary materials and parts from the storage shelf, places them on the cart, travels the cart to the assembly site of the product that is the customer, and collects the materials and components on the cart. The operation of transferring (or loading) to a shelf is generally performed.
Instead of carrying by the carriage, a long conveyor is laid and transferred. Alternatively, the pallet is transported by a forklift or transported by a tow cart that automatically operates along a taxiway.
However, in the case of adopting not only a carriage but also a conveyor, a forklift, or a towing carriage, the conventional article transfer method is that an operator takes out necessary materials and parts from a storage shelf and places them on a carriage or a conveyor. After being transported to the previous assembly site, etc., the work of moving the transported materials and parts from the cart and conveyor to the same shelf is repeated.
Depending on the type and quantity of the transported article, it is of course possible to use a dedicated transshipment robot or the like to carry out the work of transferring the article.

For example, a transfer device described in Patent Document 1 below connects a supply conveyor that carries many types of articles to a buffer conveyor, sorts the conveyed articles by type, and the sorted articles are flow shelves for each type. It is the structure which moves to a carrying-out conveyor below by gravity action, and is the structure which provided the cutting-out apparatus which takes out each article | item automatically to the said flow shelf automatically. Therefore, the necessary number of articles on each fluid shelf is automatically sent to the carry-out conveyor by the cutting device.
However, although there is no particular mention, the work of loading articles onto the supply conveyor and the work of unloading articles carried by the carry-out conveyor from the conveyor and loading them onto the intended shelf, etc., are done manually by workers as before. It may be done by a dedicated transshipment robot.

A guide arm 26 is provided to guide the movement of the shelving cart 3 that comes into contact with the shelving cart 3 and approaches .

The article transfer system according to the present invention transfers (reloads) the transported object W between the supply shelf 1 for delivering the transported object W and the shelves 3, and is transported between the shelves 3 and the demand shelves 2. Delivery (transshipment) of the goods W can be realized by an operation of simply pressing the shelf cart 3 against the supply shelf 1 and an operation of pressing the shelf cart 3 against the demand shelf 2. Therefore, it is not necessary to stop the shelves 3 near the supply shelf 1 or the demand shelf 2 and perform the loading or unloading work of the transported object W as a manual work of a worker or as a mechanization work by a transshipment robot. Reloading of the transported object W can be performed quickly and easily, and significant labor saving, efficiency and efficiency can be achieved. This point is achieved regardless of whether the shelving cart 3 is a hand cart that is driven by human power, an automatic cart that travels on a track using power, or an automatic cart that runs along a taxiway. .

The article transfer system according to the present invention has a configuration in which a supply shelf 1 for delivering a transported object W, a shelves 3 and a demand shelf 2 that is a demand destination of the transported object W are combined and applied to transporting articles for various purposes. can do.
And the supply shelf 1 of Claims 1-3 which comprise the goods transfer system of the said invention is the front fall of the angle which advances the to-be-conveyed object W supplied with the goods management shelf, the conveyor, etc. by the effect | action of gravity. The first half sliding support member 11 and the second half sliding support member 12 arranged in series at an inclination are divided into two parts. Since the trunnion shaft 15 provided at a position slightly rearward from the position is installed so as to be rotatable by a fixed rotation angle in the vertical direction like a seesaw, the transported object W that has entered the supply shelf 1 slides in the latter half. When boarding on the support member 12, the sliding support member 12 in the latter half is further tilted forward and downward due to weight imbalance, and the forward force of the conveyed object W is increased. However, the stopper 16 stops the forward movement of the conveyed object W. At the same time, the rear end portion of the sliding support member 12 tilted as described above is lifted, and the next transported object W2 that has subsequently entered the same supply shelf 1 is pressed and waited.

Next, the shelf cart 3 according to claims 5 and 6 is made to approach the supply shelf 1 waiting in the above state, and the inclined plate 31 on the front surface thereof is for releasing the stopper protruded forward from the shelf frame of the supply shelf 1. When further pressure is applied at the stage of contact with the tip of the arm 16b, the stopper releasing arm 16b is rotated downward along the inclined plate 31, and the stopper 16 is moved along with the rotation of the stopper releasing arm 16b. Subduction is released. Therefore, the transported object W1 placed on the sliding support member 12 in the latter half is released from the restraint, moved forward by the gravitational action, and transferred onto the shelves 3. Thus, the transfer (reloading) of the object to be conveyed from the supply shelf 1 to the shelves 3 can be quickly and easily performed only by the operation of the “Karakuri”, so that significant labor saving, efficiency, and efficiency can be achieved.
In addition, when the transported object W1 of the first order on the sliding support member 12 in the latter half part of the supply shelf 1 moves forward by gravitational action and moves onto the shelf cart 3, the sliding support member 12 in the latter half part is used for restoration. The elastic body 17 is forcibly restored to the original gentle inclined posture. Therefore, the next-order transported object W2 that has been stopped while being placed on the sliding support member 11 in the first half quickly advances by gravity and proceeds to the sliding support member 12 in the second half, and the next shelf cart 3 Wait for approach.

  On the other hand, the shelf cart 3 that has received the transported object W from the supply shelf 1 as described above proceeds toward the demand shelf 2 that is the demand destination of the transported object W. The shelves of the shelves 3 are positioned at a level that is equal to or slightly higher than the sliding support member 32 for feeding, which is fixed at a forward and downward inclination at which the object W is fed forward by gravity. An object to be conveyed W that is configured to enter the object to be conveyed and that is arranged in parallel with the sending sliding support member 32 and supports the object to be conveyed W is supported. During movement of the shelves 3, the one-way stopper 36 installed at the front end of the receiving sliding support member 34 prevents the conveyed object from slipping out (falling).

Next, in the demand shelf 2 according to claims 7 and 8, when the shelf cart 3 approaches, the action portion 24 protruding from the shelf frame of the demand shelf 2 comes into contact with the height variable link 37. When the rack 3 is pushed further strongly, the height-variable link 37 that receives the pressure is refracted in an intermediate state, and the receiving sliding support member 34 tilts the one-way stopper 36 according to the refraction. Thus, when the one-way stopper 36 sinks to a position lower than the upper surface of the sending sliding support member 32, the unsupported transported object W moves forward on the sending sliding support member 32 by the gravitational action and promptly reaches the demand shelf 2. Change to.
In this way, the delivery (reloading) of the conveyed object W from the shelf cart 3 to the demand shelf 2 also proceeds to the demand shelf 2 as the shelf cart 3 moves, and the action portion 24 protruding from the shelf frame of the demand shelf 2 is variable in height. Since it is realized only by the operation of contacting the link 37 and applying pressure, significant labor saving and efficiency can be achieved.
On the contrary, using the pulling action when the shelf cart 3 is separated from the demand shelf 2, the restoring action unit 25 pulls back the height variable link 37 refracted into the folded state and restores it to the straight state. The sliding support member 34 for receiving and the sliding support member 32 for sending out again return to the original receiving object receiving state. Therefore, the shelf cart 3 may be advanced toward the supply shelf 1 again as it is, and the next receiving work W can be received.

The shelf surface of the demand shelf 2 includes a sliding support member 21 arranged at a forward and downward inclination of an angle that causes the conveyed object W provided from the rack 3 to move forward by a gravitational action, in the traveling direction of the conveyed object. Since the stopper 22 is provided at the front end, the conveyed object W received from the shelves 3 is moved forward on the sliding support material 21 and used for demand. That is, from the demand shelf 2 side, it is not necessary to make any effort to the received transported object W, and it is possible to save labor and efficiency in this sense.
The demand shelf 2 protrudes from the surface of the shelf frame that faces the approaching cart 3 and comes into contact with the height-changeable link 37 of the shelf cart to give contact pressure, and the height-variable link 37. The bending and bending action part 24 that refracts the middle part of the rack to the folded state, and conversely, the height variable link 37 that is refracted to the folded state by the pulling action when the rack 3 is separated from the demand shelf 2 is pulled back and straight. This is a simple configuration in which a restoring operation unit 25 for restoring the image is provided.

There is a shelf cart that is fixedly installed at a position where a supply shelf into which the object to be conveyed is sent and a demand shelf to which the object to be conveyed is provided are separated from each other and moves between the supply shelf and the demand shelf. The article transfer system is implemented with a configuration in which the object to be conveyed is received from the supply shelf and provided to the demand shelf.
The shelf portion of the supply shelf for the transported object is configured by arranging the sliding support material in a downwardly inclined manner, and a stopper is installed at the front end position of the sliding support material to release it with the pressure that the shelving cart approaches and contacts. ing.
The shelf cart includes a stopper on which a shelf on which the object to be conveyed received from the supply shelf is placed is made of a sliding support material, and includes a stopper that prevents the object to be conveyed on the sliding support material from sliding off the shelf during movement of the shelf cart. The stopper is released by a mechanism that uses a pressure that the shelving cart approaches and contacts the demand shelf, and the object to be transported on the sliding support material is sent to the demand shelf by gravity and transferred.

Hereinafter, the present invention will be described based on illustrated embodiments.
First, FIG. 1 conceptually shows the configuration and planar layout of an article transfer system that is the basis of the present invention .
Reference numeral 1 in the figure denotes a supply shelf into which the articles to be conveyed W are sent one after another, and is fixed to the floor. In the case of the illustrated example, the supply shelf 1 is a transported object W in a form in which various articles taken out from, for example, a management shelf of a warehouse, that is, goods, parts, materials, etc. are stored in, for example, a shipping box (container). Is shown in a configuration in which it is transported by the conveyor 5 and supplied one after another.
On the other hand, the demand shelf 2 that is provided as a demand destination of the transported object W is, for example, a position away from the supply shelf 1 as a shelf for sale of goods or a temporary storage shelf adjacent to a product assembly space. Also, it is fixed on the floor.
Although FIG. 1 shows the supply shelf 1 and the demand shelf 2 in a single configuration for convenience of illustration, this is not restrictive. For example, an article transfer system can be configured and implemented by installing a plurality of shelves arranged in parallel for each type of article to be conveyed W.
The code | symbol 3 in FIG. 1 is a shelf cart which moves and communicates between the supply shelf 1 and the demand shelf 2 which are located at a distance as mentioned above. The article transport system is configured such that the shelf cart 3 receives the articles to be conveyed W from the supply shelf 1 and provides them to the demand shelf 2.
The shelving trolley 3 is implemented as a hand trolley that is manually pushed by an operator, or along an automatic trolley that runs on a track laid between the supply shelf 1 and the demand shelf 2 or with a driving power, or along a taxiway. It can also be implemented by a system in which it is configured as an automatic cart that travels and these reciprocate to transport the object W to be transported by piston.
Supply shelves 1, shelving trolleys 3, and demand shelves 2, which will be described below, are made of a resin-coated steel pipe in which a synthetic resin is thinly and uniformly coated on the outer peripheral surface of a thin-walled steel pipe. However, the present invention is not limited to this. As long as the function, mechanism, and operation described below are used, the frame structure and the material to be used are not questioned.

Next, FIG. 2A, B has shown the Example of the supply shelf 1 of the to-be-conveyed object W based on the invention described in Claim 3 and 4. As shown in FIG. The supply shelf 1 is configured to forcibly move the conveyor unit forward as a fluidized sliding support material on which the object W is loaded by a “karakuri mechanism” that uses the pressure that the carriage 3 approaches and contacts as will be described later. It is configured to incline to a lowered posture, and send and transfer the articles to be conveyed W on the conveyor unit one by one onto the shelves 3 using the action of gravity. In the present embodiment, the roller conveyor unit is used as the sliding support material, but this is not a limitation. For example, a pipe in which polyethylene having a low friction coefficient is coated with a resin on the steel pipe surface may be used. In short, as long as the transport box is a sliding support material that flows by sliding (sliding) due to the action of gravity, anything may be used regardless of its configuration and material.
In the supply shelf 1 shown in FIGS. 2A and 2B, the articles W to be conveyed stored in a transport box (container), which is not specifically illustrated, are successively supplied from the storage shelf of the warehouse, for example, by the supply conveyor 5. Is sent to. When the conveyed product W reaches the supply shelf 1, it moves to the fluid conveyor units 11 and 12 that constitute the shelf surface of the supply shelf 1, advances in the traveling direction as it is, and is sequentially sent to the shelf cart 3. It is configured.
That is, the shelf surface of the supply shelf 1 is a front half portion (front side) arranged in a series with a forward and downward inclination in which the articles W to be conveyed supplied by the supply conveyor 5 are sequentially moved forward by gravity. A conveyor unit 11 and a conveyor unit 12 in the latter half (front side in the traveling direction) are configured. Each of the conveyor units 11 and 12 is configured as a fluid type in which a plurality of wheels are arranged in a row in a longitudinal direction in a groove of a conveyor frame having an elongated channel structure so as to freely rotate.
A guide frame 13 that guides the forward movement of the article to be conveyed W is installed along the both side positions of the roller conveyor units 11 and 12 at the upper end of the shelf frame 14 that is the main structure of the supply shelf 1. In this regard, the demand shelf 2 and the shelf cart 3 described later have the same configuration.

In the supply shelf 1, the conveyor unit 11 in the first half, which is the entry side of the conveyed object W, is fixedly installed on the shelf frame 14 with the downward inclination of the angle.
On the other hand, the conveyor unit 12 in the latter half, which is the exit side of the transported object W, is slightly closer to the rear than the position in which the length of the transported object W in the traveling direction is bisected, as shown in FIG. 4A. The rack is supported by the trunnion shaft 15 provided at the position, and rotates to the shelf frame 14 so that it can be rotated forward about 20 degrees clockwise like the seesaw from the inclined posture of FIG. is set up. Reference numeral 18 in FIG. 4A is a positioning stopper for stopping the latter half conveyor unit 12 at a position of a series of inclination angles with the front half conveyor unit 11, and reference numeral 17 is a rear end side of the latter half conveyor unit 12. A restoring spring 17 of a restoring elastic body attached to the conveyor unit 12 restores the conveyor unit 12 to the original inclined posture. In addition, although the structure which used the spring for the elastic body 17 for a restoration is shown in the Example, you may use elastic bodies, such as rubber | gum or a plastic tube, for example.
Because of the above configuration, the object W1 that has entered the supply shelf 1 from the supply conveyor 5 proceeds on the conveyor unit 11 in the first half and gets on the conveyor unit 12 in the second half, and is distributed before and after the trunnion shaft 15. The weight of the transported object W1 is unbalanced, and the conveyor unit 12 in the latter half is further tilted forward and downward due to the weight of the front part having a large weight distribution (see FIG. 4B), due to the gravity of the transported object W1. Increase forward force.
However, as shown in FIGS. 4A and 4B, the forward movement of the conveyed object W1 is stopped by the stopper 16 formed of a free wheel located at the front end of the conveyor unit 12 in the latter half. At the same time, as a result of the rear end portion of the inclined conveyor unit 12 being lifted as described above, the front end of the next transported object W2 that has subsequently entered the same supply shelf 1 is pressed and waited.

Said stopper 16 is installed in the position which adjoined the front end of the conveyor unit 12 of the latter half part by the structure which protrudes perpendicularly upwards from the downward direction, and stops the to-be-conveyed object W1 advance.
As a mechanism for moving the stopper 16 in and out, a stopper releasing arm 16b supported on the shelf frame 14 so that the base end portion 16a can be rotated in the vertical direction is provided below the conveyor unit 12 in the latter half portion. It is installed so as to protrude almost horizontally forward from the front side construction surface (right side surface in FIG. 4A) of the shelf frame 14 of the shelf 1. The distal end portion of the stopper release arm 16b is curved downward and protrudes downward, and a free wheel 16c is attached to the distal end portion. A strut 16d having a free wheel forming the stopper 16 attached to the upper end is joined to the intermediate position of the stopper releasing arm 16b in a vertical arrangement. In the stopper releasing arm 16b, a restoring spring 16f is connected to an extension portion 16e protruding from the base end portion 16a to the opposite side.

In addition, although the supply shelf 1 mentioned above demonstrated the structure in the case of carrying two or more to-be-conveyed objects W sequentially, it is not this limitation. When the objects to be conveyed W are loaded one by one , as in the invention described in claim 1 , a single sliding support material in which the entire length of the shelf on which the objects to be conveyed W are placed is fixed to be inclined downward. The stopper 16 that stops the forward movement of the transported object W is protruded upward at a position close to the front end of the sliding support member.
Alternatively, as in the invention described in claim 2 , the trunnion shaft 15 provided at a position slightly rearward from the position where the entire length of the sliding support member is divided into two can be rotated in a vertical direction like a seesaw by a certain rotation angle. It can also be implemented by a configuration in which the restoring elastic body 17 is installed on the shelf frame 14 and installed on the rear end side of the sliding support material.

About the shelf cart 3 which receives the to-be-conveyed object W from the supply shelf 1 of the said structure, the Example of the handcart format which an operator pushes with a hand is shown in FIG. An operator grasps and operates the grip 39 protruding rearward from both sides of the upper end portion of the carriage frame 33 with both hands. Reference numeral 30 denotes a caster wheel attached to the lower ends of the pillars at the four corner positions constituting the carriage frame 33.
The shelf cart 3 is configured to receive the transported object W from the supply shelf 1 having the above-described configuration by a gravity action, transport it to a demand shelf 3 to be described later, and also provide it by a gravity action. When approaching the supply shelf 1 on the frame front side in the running direction of the shelf cart 3 (front side construction surface in FIG. 3), it contacts the free wheel 16c at the tip of the stopper release arm 16b of the supply shelf 1. An inclined plate 31 for applying pressure is provided.
The inclined plate 31 increases the contact pressure with the free wheel 16 c when the shelf cart 3 is strongly pressed toward the supply shelf 1 and rotates the stopper release arm 16 b downward along the forward inclined angle of the inclined plate 31. It is installed at. That is, the free wheel 16c is expected to function as a kind of cam follower.
As described above, the shelves 3 are moved closer to the supply shelf 1, and the inclined plate 31 on the front surface of the shelves is brought into contact with the free wheel 16 c at the tip of the stopper release arm 16 b to apply downward pressure. The arm 16b is rotated downward. With the downward rotation of the stopper release arm 16b, the stopper 16 is lowered together with the column 16d. Then, as a result of the stopper 16 being submerged until it becomes lower than the upper surface of the conveyor unit 12 in the second half of the supply shelf 1 as shown in FIG. As described above, the transported object W1 quickly moves forward on the conveyor cart 3 by the action of gravity on the conveyor unit 12 which has already been largely inclined downward as shown in FIG. 4B due to the weight of the transported object W1. Change to.

In addition, in the front side construction surface (right side surface of FIG. 5) of the shelf frame 14 which is the main structure of the supply shelf 1,
Even when the transported object W is light and gets on the conveyor unit 12 in the latter half, for example, in the balance with the action force of the restoring spring 17, the latter half is not inclined as much as expected. A forcible bar 19 that forcibly inclines the conveyor unit 12 in a part downward is protruded slightly downward from the horizontal direction. The front end portion of the forcible bar 19 is curved downward so that it can easily go under the frame structure (particularly the horizontal member) of the shelf cart 3.
In short, when the shelf cart 3 is moved closer to the supply shelf 1 to receive the conveyed object W, the downward inclination of the conveyor unit 12 in the latter half is insufficient, and the conveyed object W does not move even if the stopper 16 is lowered. Even if the vehicle does not move forward promptly, the forcing bar 19 always sunk under the frame structure (particularly the horizontal member) of the shelves 3 as the shelves 3 approach, It is forcibly inclined forward and the conveyed object W on the conveyor unit 12 always moves forward by gravitational action and transfers to the shelf cart 3.

In order to make the transfer of the transported object W1 smoothly, the shelf surface of the shelves 3 is moved forward by the conveyor unit 12 in the rear half of the supply shelf 1 around the trunnion shaft 15 as shown in FIG. It is configured to have a height substantially equal to the height of the front end portion that is largely inclined downward and has a forward tilting posture in which the conveyed object W1 moves forward by gravity.
As shown in FIG. 3, the shelf surface of the shelves 3 is first provided with a conveyor unit 32 for delivering the transported object W as means for receiving the transported object W that moves forward from the supply shelf 1 by gravity. In the embodiment of FIG. 3, two rows parallel to the central portion of the shelf surface, respectively, to the carriage frame 33 at a forward and downward inclination of the angle at which the articles to be conveyed W are fed forward by the gravitational action in the traveling direction of the shelf carriage 3. It is fixedly installed.
Next, in the arrangement parallel to both the outer side positions of the delivery conveyor unit 32, the conveyor unit 34 for receiving the object W is at least approximately horizontal (or slightly higher) than the delivery conveyor unit (or slightly higher). It is installed at a slight forward downward inclination in the approach direction of the conveyed object W).
The receiving conveyor unit 34 falls to the front end position in the feed-out direction of the transported object W and falls in the approaching direction of the transported object W (see FIG. 5), but the vertical vertical standing shown in FIGS. 4A and 4B The one-way stopper 36 that does not fall from the state in the feeding direction of the transported object W (counterclockwise direction in FIGS. 4A and 4B) prevents the transported object W from sliding (falling) while the shelf cart 3 is moving. It is installed as a means to prevent.
Accordingly, the stopper 16 of the supply shelf 1 is lowered to a position lower than the upper surface of the conveyor unit 12 in the latter half part of the supply shelf 1 as shown in FIG. When the first-order transported object W1 moves forward by the gravity action, the transported object W1 is smoothly transferred onto the receiving conveyor unit 34 of the shelf cart 3 as it is.

Next, the receiving conveyor unit 34 that constitutes the shelf surface of the shelf cart 3 has a horizontal shaft 35 in which the leading end in the direction in which the conveyed object W enters is a component of the cart frame 33 as shown in FIG. It is supported so that it can rotate in the vertical direction. On the contrary, in the same receiving conveyor unit 34, the front end portion in the delivery direction of the conveyed object W is rotatably connected to the upper end portion of the variable height link 37. This variable height link 37 is formed by connecting a middle portion 37a in the height direction so that it can be folded, and its lower end is connected to the horizontal shaft 33a at the bottom of the carriage frame 33 in the front-rear direction of the shelf carriage 3 in the traveling direction. It is connected so that rotation in the direction is possible. As shown in FIG. 3, the variable height link 37 is formed by combining two in a bowl shape, and the front end portion of the receiving conveyor unit 34 is rotatably connected to the horizontal shaft 37 b at the upper end portion thereof.
Therefore, FIG. As shown in FIG. 10, when the variable height link 37 is bent at the intermediate portion 37 a in a folded state, the front end of the receiving conveyor unit 34 and the one-way stopper 36 are moved according to the bending operation of the variable height link 37. When the one-way stopper 36 sinks to a position lower than the upper surface of the delivery conveyor unit 32, the article W to be transported placed on the delivery conveyor unit 32 is used for delivery. According to the forward downward inclination of the conveyor unit 32, the vehicle moves forward on the demand shelf 3 described later by the action of gravity.

Next, FIG. 6 shows an embodiment of the demand shelf 2 that receives the transported object W that has been transported by the shelf cart 3 having the above configuration.
The shelf surface of the demand shelf 2 is transported by the shelving cart 3 having the above-described configuration, and is supplied with the fluid type conveyor unit 21 so as to receive the transported object W that has been moved forward from the fluid type conveyor unit 32 by the action of gravity. Are arranged at a forward and downward inclination at an angle at which the conveyed object W sequentially advances by gravity. Naturally, as shown in FIG. 9, the shelf surface of the demand shelf 2 is such that the starting end of the conveyor unit 21 (the end portion on the incoming side of the conveyed object W) forms the shelf surface of the shelf cart 3. The conveyor unit 32 is configured to have substantially the same height as the end of the conveyor unit 32 (the exit end of the object W to be conveyed), and both form a series of fluid conveyor lines.
The shelf surface of the demand shelf 2 is provided with a stopper 22 for stopping the forward movement of the transported object W at the front end in the traveling direction of the transported object W in the conveyor unit 21. Therefore, the transported object W that has entered the demand shelf 2 can be temporarily placed on the shelf surface as it is, and if it is a part, it waits until it is used for assembling the product, and in the case of a product, it also serves as an exhibition. Can do.

As shown in FIG. 6, on the shelf frame 23 of the demand shelf 2, the shelf cart 3 on which the article W is loaded approaches, on the frame surface facing the shelf cart 3, as shown in FIG. As a reaction of the operation that protrudes from the center of the frame construction surface to the front in the substantially horizontal direction, contacts the height variable link 37 of the shelf cart 3, and is further pushed into the demand shelf 2. The pushing / bending action portion 24 that increases the contact pressure with respect to the height variable link 37 and refracts the intermediate portion 37a connected to the height variable link 37 to the folded state, and conversely, the shelf cart 3 is removed from the demand shelf 2. A restoring action portion 25 is provided that pulls back the variable height link 37 that has been refracted into the bent state by a pulling action when leaving, and restores it to a straight state.
The restoring action part 25 is configured to protrude forward longer than the push-bending action part 24. The pushing / bending action portion 24 is provided at a substantially intermediate position behind the restoring action portion 25. Assuming that the height variable link 37 of the shelves 3 is a configuration in which the two are combined in a bowl shape as described above, the pushing and bending action portion 24 has two bowl-shaped shapes as shown in FIG. A wide T-shape is formed in the horizontal direction so as to strike the variable height links 37 and 37 equally and reliably in a cornering state. On the contrary, the restoring action part 25 is configured in a T-shape having a narrow width in the horizontal direction so as to pass between the two height variable links 37, 37.
Further, in the shelf frame 23 of the demand shelf 2, as shown in FIG. 6, as shown in FIG. Guide arms 26 and 26 are provided for guiding the movement of the shelves 3 coming in contact with the frame so as to perform an operation appropriate for delivery of the transported object W to be described later.

  Accordingly, when the shelf cart 3 on which the article to be transported W is placed approaches the demand shelf 2 as shown in FIG. 7 and is pressed so as to be guided by the guide arms 26 and 26, first, The restoring action unit 25 passes through the middle of the two height-variable links 37 and 37 having a bowl shape located on the front surface of the shelves 3 and allows the approach. Subsequently, the push-bending action portion 24 approaches, and as shown in FIG. 8, comes into contact with the two height-variable links 37 and 37 having a bowl shape, and hits the cornering state. Further, when the shelf cart 3 is strongly pushed toward the demand shelf 2, as shown in FIG. 9, the pushing / bending action portion 24 pushes the two variable height links 37 and 37 equally to refract them into a bent state. As the height-variable links 37 and 37 are bent in the middle direction, the shelf 3 is where the front end of the receiving conveyor unit 34 supported by the upper end of the height-variable link 37 is gradually lowered. When the one-way stopper 36 at the front end of the receiving conveyor unit 34 sinks to a level lower than the upper surface of the sending-out conveyor unit 32, the object to be transported on the sending-out conveyor unit 32 stopped by the one-way stopper 36 is transferred. The article W immediately advances due to the action of gravity and moves onto the conveyor unit 21 of the demand shelf 2. That is, the transported object W carried by the shelf cart 3 is transferred to the demand shelf 2 by itself without bothering the operator's hands, and the operator does not have to put any hand.

After the transferred object W is transferred from the shelf cart 3 to the demand shelf 2 as shown in FIG. 9, the operator simply performs an operation of pulling the shelf cart 3 away from the demand shelf 2. Then, in accordance with the backward movement of the shelves 3, the restoring action portion 25 of the demand shelf 2 collides with the restoring force receiving portion 38 of the height variable link 37 and pulls back the height variable link 37 to perform the restoring operation.
This is because when the shelving cart 3 is approaching, the restoration operation unit 25 of the demand shelf 2 passes through as shown in FIGS. 7 and 8 because the variable height link 37 is still straight. However, when the variable height link 37 is bent, the restoring force receiving portion 38 installed at a right angle rearward to the upper half of the variable height link 37 follows the bent operation of the variable height link 37. On the contrary, it rises so that the position gets up upwards. Therefore, in the process in which the shelves 3 are separated from the demand shelves 2, the restoring action unit 25 of the demand shelves 2 having a constant ground height collides with the restoring force receiving unit 38 as shown in FIG. The variable height links 37 and 37 are pulled back via the restoring force receiving portion 38 to restore the original straight state. However, as the operation of restoring the height variable link 37 to the straight state progresses, the position of the restoring force receiving portion 38 installed at a right angle rearward to the upper half of the height variable link 37 is reversed. Descends downward. As a result, as shown in FIG. 11, at the same time as the variable height link 37 is restored to the almost straight state, the restoring force receiving portion 38 finally comes off the restoring action portion 25. Therefore, the restoring action unit 25 is detached from the shelf cart 3 as it is.
In this way, the operator does not have to put any hand, and the work of transferring the object W to be transferred from the shelf cart 3 to the demand shelf 2 is completed. Therefore, the operator may operate the shelf cart 3 and move toward the supply shelf 1 in order to receive the next article to be conveyed W. Then, by repeating the movement and operation of the shelf cart 3 described above, the transfer of the transported object W can be efficiently performed with labor saving.

  Although the present invention has been described with the illustrated embodiment, the present invention is not limited to the embodiment. It should be noted that the present invention includes design changes, applications, and modifications made as necessary by those skilled in the art without departing from the scope and spirit of the present invention.
