Description

[Detailed Description of the Invention] The present invention relates to a conveyor chain equipped with a storage function for conveyed objects such as carts.

Conventionally, floor conveyors (hereinafter referred to as
(simply called a conveyor) are often used. However, depending on the conveyor, there are cases where a conveyor is required not only to convey objects continuously, but also intermittently, and also to have the function of storing the objects to be transported, in production lines such as assembly and painting. Many conveyors of this type have been developed and improved in the past. For example, as shown in Fig. 1, conveyors are installed in parallel on the transport side and return side, and the conveyed items are stored at a predetermined position while sliding on rollers attached to the conveyor, and wire ropes are also used. There are devices (not shown) that have a function of keeping the wire rope running at all times, conveying the object while holding the wire rope, and automatically releasing the wire rope at a certain position and storing it. .

By the way, the conveyor chain according to this invention also
It is used for the same purpose as the above-mentioned conveyor, and it eliminates the need for oversized equipment in conventional conveyor equipment.
In order to resolve deficiencies such as incomplete storage functions and automation issues, a tilting dog is installed between the chain pitches, and a weight is attached to the tilting dog to enable seesaw movement, allowing for the transportation and stopping of conveyed items, as well as It satisfies the three functions of storage and, as a specific example, is aimed at automating work and saving labor in production lines for motorcycles, automobiles, etc.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 and 3. Here, we will take the trolley 1 as an example of the transported object, and describe the case where parts to be assembled into the machine body are loaded and transported on the trolley 1. A running roller 12 that allows the upper plate 11 to run on a support rail 13, an anti-shake roller 14 that prevents lateral vibration during travel, a conveying metal fitting 15 on which a tilting dog (hereinafter simply referred to as "dog") to be described later comes into contact, and a lower part. The conveyor chain 2 according to the present invention (hereinafter simply referred to as "chain") is composed of three strips, and has an extending auxiliary plate 29 and a stop plate 16 at the tip of the auxiliary plate 29. The chain 2 runs on rails 18, 18 via side rollers 17, 17, and is connected with inverted T-shaped link plates 19 at appropriate intervals. with pin 27 and also with dogs B and b
are pivotally supported by pins 28 on the supports 21, 21, respectively,
On the upper sides 19a and 19b of the link plate 19, the side to which the weights 22 of dogs A, B, and b are attached is downward on the transport side, and the side on which the weights 22 of dogs A, B, and b are attached is downward, and on the return side
The sides of B and B on which the weight 22 is not attached are located upward, and are in contact with the upper sides 19a and 19b, respectively, so as to force an inclined posture. Further, the dog A on the transport side and the dog A on the return side are kept substantially horizontal by the support pin 25 due to the weight difference due to the weight 22. That is, pins 27 and 28 are rotatably attached between the same pitches of dogs A and a and dogs B and b, respectively, but one end of dog A (regardless of whether it is on the conveyance side or the return side in FIG. The left side of the dots is "one end" and the right side is "the other end"
It is called. However, here, a weight 22 is provided on the transport side (explanation will be added here on the transport side), and a weight 22 is provided on the other end of the dog a, and a roll 23 is provided on one end. Weight 22 and roll 2 are on the other end of dog B.
3, and a weight 2 at one end of dog b.
2 and the other end are provided with a roll 23, and each of the dogs A, a, B, and b is provided with a weight difference by a weight 22, and the upper side 1 of the link put 19 is
The tips of dogs A, a, B, and b are forcibly abutted against pins 27 and 28 of dogs 9a and 19b, and the dogs A, a, B, and b are rotated toward the return side by rotating the chain 2 toward the return side. In addition, the structure is such that the dog A is held substantially horizontally on the transport side and the dog a is held substantially horizontally on the return side by support pins 25, respectively. The chain 2 is hung on sprockets 24 arranged at both ends of the neutral plane of the truck 1, and the sprockets 24
4 causes the chain 2 to travel, and the carriage 1 is conveyed by pulling the conveyor fitting 15 by the dog A or dog B.

Next, to explain the operations of dogs A, a, B, and b, first, on the transport side, the leading dog A is raised to the right by the weight 22, while dog a
should be downward to the right due to the weight 22, but it hits the support pin 25 fixed to the support 21 and is kept in a substantially horizontal state, and as the chain 2 advances,
The dog A passes through the conveyance fitting 15 without touching it, and the other end of the dog A touches the conveyance fitting 15 once, but after being pressed by the conveyance fitting 15 and passing through, the dog A is immediately put into an oblique position by the weight 22 and the dog A is placed on the upper side 19a. One end of A contacts and returns to the above-mentioned upward-rightward state. The other end of the dog B contacts the upper side 19a due to the weight 22, and the dog B forms a "C" shape with one end facing the dog A with the other end facing upward to the left. , the trolley 1 is transported by being pulled by dog B. Furthermore, dog b is forced by the weight 22 to the upper side 19b.
Since the dog B is brought into contact with the dog B and is configured to take an oblique posture, the dog b forms an "X" shape with respect to the dog B, but in this case, the dog b is not able to be pulled with the conveyance fitting 15. There is no relationship. In the end, the conveying metal fitting 15 passed over dog A and came into contact with dog B.
This prevents dog A from always leading faster than chain 2, and is pulled by dog B and between dogs A and B.
is held and the trolley 1 is transported to the destination point. The cart 1 that has been transported is placed at a predetermined position, and the slanted end of the stopper 26 operated by a cylinder (not shown) hits the roll 23 of the dog B.
The other end of dog B, which is downward to the right, is the stopper 2.
6 forcibly scoops up the dog B, and the other end of the dog B that was in contact with the upper side 19a lifts up, so that the one end of the dog B is quickly released from contact with the conveying metal fitting 15, and the cart 1 stops. Furthermore, the truck 1 that has been towed by the subsequent dog B due to the running of the chain 2 is stopped by the stop plate 16 attached to the auxiliary plate 29 provided at the rear of the previous truck 1, which performs the same function as the stopper 26 described above, and the dog B The other end can be scooped up and stopped in the same way, and while the leading cart 1 is stopped, the following carts 1 can be necessarily stopped and stored, and conversely, the sprocket 24 allows the cart 1 to be When transporting the truck to the return side, when the truck 1 tries to advance faster than the speed of the chain 2 based on the inclination of the track, the dog A
Regarding 5, the above self-propulsion is prevented. Further, when the stopper 26 is released, one end of the dog B hits the conveyor fitting 15 and the cart 1, which is no longer needed after completing a predetermined work, starts towing.

On the other hand, on the return side, the chain 2 and the truck 1 turn via the sprocket 24, and the dogs A, a,
B and b are turned in opposite directions due to the rotation, but the other end of dog A tries to be downwardly tilted to the right by the weight 22, but is held in a substantially horizontal state by the pin 25, and does not come into contact with the conveyor fitting 15. The relationship is resolved, and dog a goes down to the right, dog B goes up to the right, and dog b goes down to the right. Therefore, in the cart 1, the other end of the dog b comes into contact with the transport fitting 15, and the dogs a, b, and B come into contact with one end or the other end of the upper side 19a or 19b, respectively, and are forcibly assumed an oblique posture. A conveyance fitting 15 is held between a and b, and the carriage 1 is conveyed by the conveyance fitting 15 engaged with the dog b, and the speed of the chain 2 is controlled by the dog a inclined in the opposite direction to the dog b. When the truck 1 runs out of control sooner, the self-running is prevented. Also,
On the return side as well as on the transport side, one end of the dog b is stopped by the upper side 19 due to the stop plate 16 provided at the rear of the following truck 1.
Since the contact with b is to be broken, the conveyor fitting 15
When the leading truck 1 is stopped, the first truck 1 is stopped and stored continuously.

As mentioned above, in one pitch, dog A and a
In addition, the chain 2 equipped with dogs B and b can accurately pull and transport the trolley 1, stop it at a predetermined position, and store a certain number of each at will, whether on the transport side or the return side. is possible. Moreover, dogs A, a, B and b
Utilizing the own weight of the weights 22 provided in each,
The above-mentioned transportation, stopping, and storage operations can be performed smoothly following the work on the production line without installing any special control device.Especially, after the cart 1 is stopped at the desired position, Because the stop plate 16 provided on the truck 1 stops the following truck 16 before the preceding truck 1 collides with the preceding truck 1,
A conveyor device that can stop the leading truck 1 and the following truck 1 without applying an impact from a rear-end collision, and can also be shared on the return side for conveyance by the dog of the chain 2, and requires a storage function. The chain 2 according to the present invention is excellent in meeting the requirements.
