[Detailed Description of the Invention] The present invention relates to a conveyor device in which a moving trolley for conveying articles that can be moved along a certain route is held and towed by a driving chain stretched along the said route, and particularly the conveyor device. It concerns storage mechanisms.

To be more specific, the driven member attached to the front end of the truck is pushed by the pusher of the driving chino to tow and move the truck, and if there is a preceding truck that is stopped, the driven member attached to the front end of the truck is Rotate the pusher knocking claw that pairs with the pusher using a provided guide attachment,
Regarding an improvement of a storage-capable conveyor device, which swings the pusher forward and downward by rotating the knocking claw to release the engagement with the driven member, thereby automatically stopping the following cart, The purpose of the present invention is to provide a conveyor device that can perform a desired storage function even when the cart is set facing backward on a moving route.

Embodiments of the present invention will be described below based on the attached illustrative drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a moving trolley for transporting articles, which has wheels 3 guided by guide rails 2. As shown in FIG.

Reference numeral 4 designates a trolley driving chest stretched out on the floor so as to be located below the trolley 1, and on the upper side there is a traveling path section 6 that moves in the direction of advancing the trolley (in the direction of arrow 5). It is stretched so that a backward path section 7 that moves in the opposite direction is located on the lower side, and is driven by a toothed wheel at one end of the path.

As shown in FIGS. 3 to 5, the bogie driving chino 4 is made up of a pair of left and right chinos 8a and 8b connected and integrated by connecting members 9 at regular intervals in the longitudinal direction.
A guide roller 11 is supported between the left and right links on each link connecting pin 10 of both chains 8a and 8b, and guide rails 12 and 13 for guiding the guide roller 11 are provided in two stages, upper and lower.

The connecting member 9 is a pair of left and right side plates 14 connected at both ends and the center by a horizontal plate 15, and the side plates 14 are connected to opposing links 16a, 1 of the chanos 8a, 8b.
6b with a fixture 17.

A pusher pushing claw 1 forces a pair of front and rear parts on this connecting member 9.
8 and a pusher 19 are pivotally connected by a shaft 20.21.

Both of these 18, 19 are located between the side plates 14, and each has a weight part 22, 23 at the rear end, and in the forward path part 6 of the chino 4, the weight part 22, 23 is moved by gravity at both the front and rear ends. It is held in a predetermined upright position by coming into contact with the horizontal plate 15 of.

The pusher 19 has a rearward portion 19a located above and in front of the shaft 21, and a secured portion 19b extending further forward than the rearward portion 19a.

The pusher knocking claw 18 has a wider abutted part 18a that protrudes left and right than the backing part 19a of the pusher 19 at a position above the shaft 20, and further has a engaged part 18a above the engaged part 19b of the pusher 19. It has a push-down part 18b that extends rearward so that its tip ends overlap.

On the other hand, in the cart 1 shown in FIGS. 1 and 2, a driven member 24 is provided on the lower side of both front and rear ends of the bottom surface at a height where the pusher knocking claw 18 and the pusher 19 in the upright state do not come into contact with each other.
and a pair of left and right guide attachments 25a that sandwich this.
, 25b are provided in a protruding manner.

As shown in FIGS. 3 to 5, the driven member 24 is provided in a protruding position at a position where it is pushed by the backing part 19a of the pusher 19, and the pair of left and right guide attachments 25a and 25b are connected to the pusher tilting claws. The contact portion 18a is protruded at a position where it can come into contact with both left and right end portions of the contact portion 18a.

The usage and effects will be explained below.

As shown in FIGS. 1 and 3, when the driven member 24 at the front end of the truck 1 is engaged with the rear part 19a of the pusher 19 in the forward path section 6, the truck 1 is As the cheno 4 rotates, it is pulled and propelled by the pusher 19 in the direction of the arrow 5.

Now, as shown in Fig. 1, when there is a stopped leading bogie, a pair of left and right guide attachments (25a, 25b) protruding from the rear end of the stopped leading bogie are connected to the following bogie 1.
As the pusher knocking claw 18 located immediately in front of the pusher 19 that is pulling the vehicle approaches, both left and right ends of the abutted portion 18a of the pusher knocking claw 18 stop and the rear end of the leading truck approaches, as shown in FIG. Ga-id attachment 2
5a and 25b, the pusher knocking claw 18 pushes the weight part 2 backward and downward around the shaft 20 as shown in the figure.
It is forced to turn against the gravity of 2.

Therefore, the push-down portion 18b is the secured portion 19 of the pusher 19.
b is pressed down to rotate the pusher 19 forward and downward around the shaft 21 against the gravity of the weight part 23.
Leave from 4 downward.

Therefore, the following bogie 1 is dynamically de-driven and stops immediately after the stopped preceding bogie.

In this way, the following carts automatically stop one after another, and are stored in a state of continuous movement despite the rotation of the driving chino 4.

Note that the guide attachments 25 a and 25 b are
The length is such that the pusher knocking claw 18 can be held in the rotated state until the rear part 19a of the pusher 19 passes under the driven member 24 at the rear end of the stopped leading truck with its head lowered.

In the method of use of the above embodiment, the pair of left and right guide attachments 25 a and 25 b at the front end of the truck 1 and the driven member 24 at the rear end of the truck 1 are unnecessary.

However, when the trolley 1 is moved horizontally in parallel without making a U-turn and is propelled forward and backward on another route, the guide attachment mentioned above is pointed out to be unnecessary.
a, 25b and the driven member 24 can be used to perform trolley drive and automatic storage functions.

That is, the trolley 1 can be used without any directionality.

The front and rear carts 1 stored in the above manner are as shown by the imaginary lines in FIG.
4 and the driven member 24 at the front end of the rear truck are stopped in close proximity or in contact.

In such a state, the moving pusher knocking claw 18 is attached to the guide attachments 25a and 25b at the front end of the rear truck.
Since the pusher 19 immediately after the pusher knocking claw 18 passes through the vehicle while being rotated backward and downward by the guide attachments 25a and 25b at the rear end of the front truck that are continuous therewith, the pusher 19 located immediately after the pusher knocking claw 18 is also attached to the front and rear adjacent driven members. 24
It will pass in a state of being rotated forward and downward without engaging with it.

This pusher passage action is performed in the same way even without the guide attachments 25 a and 25 b at the front end of the truck.

In order to stop the leading truck 1 during storage, a stopper that performs the same function as the guide attachments 25 a and 25 b may be provided at the starting end of the storage line so as to be movable laterally.

Therefore, when this stopper is released, the pusher 19 engages with the driven member 24 at the front end of the leading stopped truck, and the leading stopped truck is again pulled and driven by the driving cheno 4.

The subsequent stopped carts are also sequentially towed and driven as the immediately preceding stopped cart moves forward.

When the pusher knocking pawl 18 and the pusher 19 are moved from the forward path section 6 to the backward path section 7 by rotation of the driving cheno 4, the direction of the biasing force by the weights 22 and 23 changes as shown in FIG. Since it is upside down, the pusher tilting claw 18 and pusher 19 are attached to the guide attachments 25a and 25.
The secured portion 19b of the pusher 19 contacts the central horizontal plate 15, and the pressed portion 18 of the pusher tilting pawl 18 is rotated outwardly.
It is stabilized in the collapsed state where b is in contact with it and moves in a go-around.

The present invention can be implemented as described above, and its greatest feature is that the driven members 24 are provided downwardly projecting at the same positions in the left and right directions at both the front and rear ends of the moving cart for transportation. On both left and right sides of both liquid moving members 24, the driven members 2
Guide attachments 25a and 25b for pushing down the pusher and lowering the claws, which are longer in the front and back direction than the pusher 4, are respectively provided with their outer ends aligned and protruding downward, and the bogie driving cheno 4 has the pair of left and right guide attachments 25a and 25b. a pusher 19 which can be raised and lowered and which can engage only the inner end of the driven member 24 without coming into contact with the driven member 24; Pusher knock down claw 1
8, and the pusher tilting pawl 18 is provided with a wide abutted portion 18a whose left and right ends abut against the guide attachments 25a, 25b and are pushed down.

According to the cart type conveyor device of the present invention, there are two cases in which the cart is set on the moving path in a forward-facing state in which the drive chenograph 4 moves from the rear end to the front end unique to the cart. On the other hand, in any case where the truck is set on the movement path in the reverse direction where the driving cheno 4 moves from the front end to the rear end of the truck, the pusher 19 of the driving chino 4 can be By engaging both ends of the driven member 24 located on the forward direction side, it is possible to propel the cart while keeping the relative longitudinal position of the cart with respect to the pusher 19 always constant with respect to the moving direction, and also in the forward direction state and reverse direction state. In either case, it is possible to reliably perform the automatic storage function of automatically canceling the propulsion of the bogie immediately after the preceding stopped bogie.

Further, according to the present invention, since the driven member 24 and the pair of left and right pusher knocking claw lowering guide attachments 25 a and 25 b are provided at the front and rear ends of the cart, respectively, to protrude downward, the pusher knocking claws 18 are Like the conventional device in which only the front and rear ends of the truck are laid down by the guide attachments 25a and 25b, and recesses are formed on the bottoms of both the front and rear ends of the truck to constitute parts corresponding to the driven member and the guide attachment. While passing between the front and rear ends of the truck, the drive chenna 4
The resistance and noise acting on the pusher and the wear of the pusher claw are reduced.

In addition, in terms of manufacturing, it is only necessary to attach the driven member 24 and the guide attachments 25a and 25b, which are small parts, to the bottom of both the front and rear ends of the cart, so it can be carried out at a very low cost, and it is possible to replace the conventional cart of this type. It is also possible to easily improve the conveyor device and obtain the above-mentioned effects.

However, on the other hand, as mentioned above, the driven members 24 protruding from the bottom of both the front and rear ends of the truck are vulnerable to contact with other objects, etc.
However, according to the present invention, long guide attachments 25a and 25b are provided on both sides of the driven member 24, which are long in the front and back. Since the drive member 24 is effectively protected from contact with other objects, the fear of the above-mentioned inconvenience is almost eliminated, and good engagement between the driven member 24 and the pusher 19 is always achieved. can be made.
