Description

Description: BACKGROUND OF THE INVENTION (Industrial Application Field) The present invention relates to an article transfer apparatus, in particular, a transfer apparatus for transferring an article loaded on a carrier such as a pallet or a tray from one carrier to another carrier. It is about.

(Prior Art) In factories and the like, it is widely used to use a carrier such as a pallet in order to improve cargo handling efficiency of articles. In factories that require a clear environment, such as IC factories and pharmaceutical factories, goods are loaded on dedicated clean pallets and trays for cargo handling and transported outside. It is indispensable to transship to wooden pallets for use.

Conventionally, such transshipment of articles is performed manually or by using a pallet reversing machine or a robot palletizer.

The pallet reversing machine carries one pallet loaded with articles into the reversing machine, places the other pallet on the article and performs a predetermined pressing support, and then turns the reversing machine 180 degrees to lower the other pallet. The transfer is completed by removing one of the pallets as described above, and the robot palletizer transfers the goods from one pallet to the other pallet for each article by a robot hand.

(Problems to be Solved by the Invention) With a pallet reversing machine, it is not possible to automate the transshipment of articles.
It is necessary to input and learn the size of the original package, the arrangement of the articles and the number of stacking stages, and these changes must be dealt with one by one, which is troublesome and cannot be completely automated. In addition, none of the above-mentioned methods provide satisfactory performance in terms of work efficiency, processing ability, prevention of damage to articles, complete automation, and the like.

An object of the present invention is to solve the above problems.

(Means for Solving the Problems) In order to solve the above problems, an article transfer device according to the present invention includes a sliding plate configured to allow an article to slide in a lateral direction, and a first sliding plate on a side of the sliding plate. First moving means for moving the loading platform, locking means for locking the first loading platform, which has reached the side of the slide plate, to the slide plate side in the same plane, and first locking means below the slide plate. A second moving means for moving the second carrier is provided, and an article pushing means for moving an article loaded on the first carrier to an upper side of the slide plate and sliding the article,
And a carrier moving means for moving the second carrier below the sliding plate in the same direction as the sliding direction of the article, wherein the carrier moving means corresponds to the article on the upper side of the sliding board. The second carrier is configured to be moved in synchronization with the sliding of the article by the article pushing means, and a third moving means is provided at a destination of the second carrier.

(Operation) In the above configuration, the first bed on which articles are loaded is:
It is moved to the side of the slide plate by the first moving means, and locked to the slide plate side by the lock means. The second carrier is moved below the slide plate by the second moving means.

In this state, the article pushing means is operated to push the articles loaded on the first carrier, move the articles from the first carrier onto the slide plate, and slide on the slide plate. The first loading platform is locked in the same plane on the sliding plate side by the locking means, and since the sliding plate itself can easily move the articles, the load does not collapse in these processes.

When the article is slid on the slide plate by the article pushing means in this way and reaches a position corresponding to the lower second carrier, the carrier moving means is synchronized with the sliding of the article by the article pushing means to the second carrier. The carrier is moved in the direction of the third moving means. Therefore,
The article reaches the edge of the sliding plate in synchronization with the second carrier, and then sequentially moves onto the second carrier. In this way, the articles are transferred to the second loading bed that is moving in synchronization, so that the articles do not collapse in such a process.

As described above, the articles loaded on the first loading platform can be transferred to the second loading platform via the sliding plate and moved to the predetermined position by the third moving means. Automation can be easily performed.

(Example) Next, an example of the present invention will be described with reference to the drawings.

First, in FIG. 1, reference numeral 1 denotes a sliding plate configured to allow the article 2 to slide in the lateral direction, and a first moving means 4a for moving the first carrier 3a to the side of the sliding plate 1. And second moving means for moving the second carrier 3b below the sliding plate 1.
4b. These first moving means 4a and second moving means 4b can be constituted by a suitable conveyor such as a roller conveyor. Reference numeral 5 denotes a lock means 5 for locking the first loading platform 3a reaching the side of the slide plate 1 on the same side as the slide plate 1;
Is a stop plate 6 provided on the slide plate 1 side and a first moving means 4a.
And a pressing device 8 which is provided at a position facing the stopper plate 6 and which can move forward and backward with respect to the stopper plate 6. In this embodiment, the stopper plate 6 is The edge of the slide plate 1 is bent in a hanging state.

Next, reference numeral 9 denotes the articles 2 loaded on the first loading platform 3a.
This is an article pushing means for moving the object 2 to the upper side of the sliding plate 1 and sliding the article. The article pushing means 9 comprises a moving base 10 configured to be movable in the sliding direction of the article 2 and a moving base 10 on the moving base 10. The push plate 11 is configured to be able to advance and retreat. The movable base 10 has a frame plate-like configuration with an opening at the bottom in order to be able to move over these positions without interfering with the first carrier 3a and the slide plate 1. An article detecting means 12 is provided on the front surface of the push plate 11. Such article detecting means
The switch 12 can be constituted by a switch which is activated by contact with the article 2 or which is activated by non-contact by proximity.

Next, reference numeral 13 denotes a carrier moving means. The carrier moving means 13 comprises a carrier pushing member 14 movably provided below the slide plate 1 and the movable base 10. An actuating mechanism that is separable is constituted by 10 and the bed pushing member 14. The operating mechanism includes a bed pushing mechanism 15 by contact between the moving base 10 and the bed pushing member 14, and a ball plunger 16 provided on one side of the moving base 10 or the bed pushing member 14.
And a loading platform returning mechanism including a ball engaging member 17 provided on the other side. Reference numeral 18 denotes a contact portion provided on the movable base 10 and in contact with the carrier pushing member 14. The contact portion 18 comes into contact with the carrier pushing member 14 when the article 2 on the upper side of the sliding plate 1 has a predetermined positional relationship with the second carrier 3b below the sliding plate 1. It has a configuration.

Further, a third moving means 4c is provided at the destination of the second carrier 3b by the carrier pushing member 14, and the third moving means 4c can also be constituted by an appropriate conveyor.

 The operation of the above configuration will now be described.

First, the first carrier 3a on which the articles 2 are stacked is moved to a predetermined position on the side of the slide plate 1 by the first moving means 4a (FIG. 2 (a)). When the first carrier 3a reaches the predetermined position in this way, the locking means 5 is operated, that is, in this case, the pressing member 7 is advanced to move the first carrier 3a in the direction of the sliding plate 1 and Press. By this operation, the first carrier 3a is locked on the slide plate 1 side in the same plane (second carrier).
Figure (b).

Next, the moving base 10 is advanced in the direction of the first loading platform 3a,
The front surface of the push plate 11 is aligned with the end surface of the first carrier 3a (FIG. 2 (c)). This operation can be controlled by an appropriate position sensor such as a limit switch. Thereafter, only the push plate 11 is moved forward while the moving base 10 is kept as it is, and stopped when the article detecting means 12 operates (FIG. 2 (d)).

By the above operation, the relative position between the end face of the first loading platform 3a and the end face of the article 2 is fixed as the relative positional relationship between the moving base 10 and the push plate 11, so that it is in a so-called memorized state.

In addition, the second carrier 3b is moved below the sliding plate 1 by the second moving means 4b in a timely manner up to this point.

In this state, when the moving base 10 is further advanced while maintaining the relative positional relationship between the moving base 10 and the push plate 11, the push plate 11 pushes the article 2 loaded on the first carrier 3a. By pushing, the article 2 is moved from the first loading platform 3a onto the sliding plate 1 and slid on the sliding plate 1 (FIG. 2 (e)).
(F)). As described above, the first loading platform 3a is provided with the locking means 5
As a result, since the article 2 is easily moved on the slide plate 1 itself, the load does not collapse in these processes.

In this way, the movable base 10 moves forward, slides the article 2 on the slide plate 1, and when the position reaches a predetermined position (second
(FIG. 3 (f) and FIG. 3 (b)), the contact portion 18 provided on the moving base 10 comes into contact with and pushes the carrier pushing member 14 which has returned to the expected position by the operation described later. The second carrier 3b is pushed via the carrier pushing member 14. The position at which the contact portion 18 provided on the movable base 10 abuts on the carrier pushing member 14 is different from the position of the second base 3b in the substantial positional relationship between the movable base 10 and the push plate 11. If the position is set as a position corresponding to the end face, at this point, the article 2 on the sliding plate 1 is in a state corresponding to the second carrier 3b in the same manner as the relative positional relationship with the first carrier 3a.

In this state, when the moving base 10 further advances,
The sliding of the article 2 by the push plate 11 and the movement of the second carrier 3b via the carrier pushing member 14 progress in synchronization.

Therefore, the article 2 slides in synchronism with the second carrier 3b, reaches the edge of the sliding plate 1, and then sequentially moves onto the second carrier 3b (FIG. 2 (g)).

As described above, the article 2 is moved to the second carrier 3b which is moving in synchronization, so that the collapse of the cargo does not occur in the process. The article 2 thus transferred to the second carrier 3b can be moved to a predetermined position by the third moving means 4c (FIG. 2 (h)).

As described above, when the article 2 is transferred from the first carrier 3a to the second carrier 3b, the moving base 10 is retracted to the original position. At the time of retreat, since the ball plunger 16 provided on one side of the moving base 10 or the carrier pushing member 14 is engaged with the ball engaging member 17 provided on the other side, the carrier pushing member 14 is With the retreat of the movable base 10, the movable base 10 is returned to the desired position, that is, toward the end of the slide plate 1 on the side of the stop plate 6 (FIG. 3 (c)).
Stop here. Then, when the carrier pushing member 14 returns to the initial position, and stops there, the engagement between the ball plunger 16 and the ball engaging member 17 is released (FIG. 3 (a)). Return to the position and wait for the next operation.

(Effect of the Invention) As described above, according to the present invention, the articles loaded on the first loading platform are transferred to the second loading platform while moving synchronously with the sliding plate therebetween, so that the load is reliably prevented from collapsing. Transfer can be performed, transfer capacity is high, and it is possible to respond to these changes without the need to input the original size, arrangement of goods and the number of stacking steps like a robot palletizer. Has the effect that complete automation can be achieved. Thus, the present invention achieves automation of transshipment from clean pallets or trays to wooden pallets for external distribution, which is indispensable for factories requiring a clear environment, such as IC manufacturing plants and pharmaceutical manufacturing plants.
