Description

[Detailed explanation of the invention] Conventionally, when handling bag products with unstable shapes, soft products such as butter, and accumulations, collections, and loads of various products on a conveyor, the products on the rear side are This has been a major hindrance when automating production equipment because it is impossible to achieve a so-called pressing state in which the product on the front side is pushed, and it is difficult to accumulate.

In addition, as a means of simply transporting the above-mentioned products using a conveyor, a packet conveyor method is generally used in which each product is placed in a packet and handled without touching each other, but this method only transports the products. It was impossible to accumulate.

The present invention has been proposed in order to eliminate the above-mentioned drawbacks of the conventional technology.The product receiver is mounted between the transfer station and the product receiver is installed between the pick-up station, and is hung between the driving and driven sprockets so as to be continuously driven. A bag product with an unstable shape that can be slid in the longitudinal direction of the chain and can be accumulated to frictionally engage with the endless table top chain that loops from the top to the bottom and then back up again. , a product platform for placing a soft product such as butter is attached to the driven sprocket, and when the product platform rotates upward, it comes into contact with the product platform by a spring force, and this rotation is prevented by contact friction force. By providing an auxiliary mechanism to assist the product, and by providing a stopper device at the transfer station and the receiving station to temporarily stop the product loading platform, the product tray can be used to prevent bag products with unstable shapes, soft products such as butter, etc. It is an object of the present invention to provide an article conveying device that can convey articles in a pressed state, can accumulate articles, and contributes to the automation of production equipment.

The present invention will be explained below with reference to the embodiments shown in the drawings. Fig. 1 is a front view of an article conveying device showing an embodiment of the invention, Fig. 2 is a sectional view taken along the line X-X of Fig. 1, and Fig. 3 is a cross-sectional view taken along the line X-X of Fig. 1. FIG. 2 is a sectional view taken along the YY line in FIG. 1;

In the figure, reference numeral 1 denotes a product platform, which is attached to the table top chain 2 so as to be slidable in the longitudinal direction of the chain, and 1a on the product platform 1 is a collar.

A sprocket 3 drives the table top chain 2, and is rotatably attached to the frame 4 via a shaft 5.

A sprocket 6 drives the sprocket 3, and is connected to a driving portion (not shown) via a chain 7.

A guide plate 8 guides the lower part of the table top chain 2 and is fixed to the frame 4.

9 is a driven sprocket rotatably attached to the frame 4, and 10 is a ball bearing rotatably attached to the tip of the lever 11.

The lever 11 is mounted so as to be able to swing around a pin 12, and the pin 12 is fixed to the driven sprocket 9.

Reference numeral 13 denotes a tension spring, and one end is attached to the lever 11 and the other end is attached to the driven sprocket 9.

Reference numeral 14 denotes a stopper for the lever 11, which is fixed to the driven sprocket 9, and the ball bearing 10 is attached to the product platform 1.
When the lever 11 is not in the engaged state, the lever 11 is pressed against it by the spring force of the tension spring 13.

A is a station where the product C placed on the top surface of the product platform 1 is transferred to a downstream device (not shown), B is a station where the product C is received from an upstream device (not shown), a and Reference numeral b designates a stopper device for temporarily stopping the product platform 1 for receiving and receiving the product C at stations A and B, respectively.

Air cylinders 15 and 15a are held by a frame (not shown) via pistons 17 and 17a, respectively.

16 and 16a are piston rods, each connected to pin 2.
0 and 20a, the stoppers 18 and 18a are rotatably held.

Pins 19 and 19a are integral with a frame (not shown), and are in a swingable relationship with stoppers 18 and 18a, respectively.

Next, to explain the operation, the table top chain 2 is always continuously moved in the direction of the arrow in FIG. 1 by the drive sprocket 3.

Here, the piston rod 16 is retracted to the air cylinder 15 side, the stopper 18 rotates clockwise about the pin 19, and when the stopper 18 and the collar 1a of the empty product platform 1 are engaged, the product platform 1 The conveyance of the product C is stopped at station B, and the product C is transferred from an upstream device (not shown) onto the empty product platform 1.

However, since the table top chain 2 is continuously moving, the two end up slipping while the product platform 1 is stopped.

When the product C is transferred to the product platform 1, the stopper device is opened by an operation opposite to that described above, and the product platform 1 carrying the product C moves in the same direction as the table top chain 2. It is carried to station A on the same chain 2.

Between the A1B stations, the product platform 1 and the table top chain 2 are not fixed, so the product platform 1 can be freely accumulated.

At station A, similarly to station B, the product platform 1 is temporarily stopped by a stopper device a, and the product C is transferred to a downstream device.

Next, the empty product platform 1 is moved in the traveling direction by the full top chain 2 when the stopper device a is released, and rotates downward according to the rotation of the sprocket 3, and the bottom is moved by the full top chain 2. It moves while hanging from the station B, and then turns upward due to the rotation of the driven sprocket 9 and reaches station B.

In this case, when the product platform 1 rotates downward by the driving sprocket 3, it can easily rotate because the direction of gravity of the product platform 1 and the direction of movement are the same, but at the rotation part of the driven sprocket 9, the gravity is Since it acts in the opposite direction to the direction of travel, an auxiliary mechanism is required to help this rotation.

In the case of FIG. 1, the force of the tension spring 13 is used to press the ball bearing 10 against the lower surface of the product platform 1, and rotation is achieved with the product platform 1 fixed to the table top chain 2.

Also, the auxiliary mechanism is from station B to driven sprocket 9.
In case the product mounting table 1 becomes pressed between the
To prevent overload, when the load exceeds a predetermined value, the ball bearing 10 rolls on the lower surface of the product platform 1 to prevent slipping.

Furthermore, even if there is a waiting time for receiving products at station B, it is possible to accumulate empty product platforms 1 in the same way.

Regarding the timing of product reception and delivery at station A1B, there are no mechanical constraints between stations A and B, so it is possible to set the timing freely. becomes easier.

FIG. 4 shows another embodiment, in which the chiffle top chain 2
Although this case is curved, the product platform 1 can be transported in the same manner as described above, and there is no difference in operation and effect.

As explained in detail above, the present invention is based on an endless table top chain that is installed between the product receiving station and the product receiving station, and is slidable in the longitudinal direction of the chain that is continuously driven. , and is equipped with a product platform capable of accumulating so as to frictionally engage with the chain, and is brought into contact with the product platform by a spring force when the product platform rotates upward to the driven sprocket,
It is equipped with an auxiliary mechanism that uses contact friction force to help this rotation, and since the table top chain can be a commercially available one, it is not as expensive as one with a special structure.

In addition, since a table top chain is used, it is possible to easily carry not only linear conveyance but also curved conveyance, and as mentioned above, this invention has an auxiliary mechanism on the driven sprocket, so when the product platform is rotated upward, the gravity of the product platform Even if it acts in the opposite direction to the direction of movement, it can easily wrap around upwards,
Not only can the product platform move from the top to the bottom due to gravity, but also the product platform can move from the bottom to the top without causing any hindrance to the product pick-up, the pick-up, and the transfer of the product at the transfer station. It is carried out smoothly, has an extremely simple structure, has no risk of failure, and does not cause an increase in costs.

In addition, using the same product platform, even bag products with unstable shapes, soft products such as butter, etc., which were conventionally considered difficult to be handled, can be pressed and accumulated on the conveyor without any problems. Automation and unmanned operation can be promoted.

The present invention can be applied to general conveyor devices, joint conveyors between mechanical devices that require timing synchronization, packaging machines, transportation stumps, automatic warehouses, etc.
