More specifically, in a slat conveyor, a plurality of slats are connected in an endless manner by connecting endless chain bands to both ends thereof, and goods are loaded on the slats and conveyed by circulating the endless chain bands. , a dispensing pin held between the slats and slidable along the side of the slat; and a dispensing pin fixedly provided below the slats, contacting the lower part of the dispensing pin and sliding the dispensing pin as appropriate. The trolley conveyor, which is installed above one side of the slat conveyor and transports the cargo in a suspended manner, moves the cargo onto the slat by the action of the payout pin and the guide plate. The present invention relates to a cargo transfer device that transports cargo while moving the cargo and continuously discharges the cargo onto a slat.

Generally, in mass production lines for home appliances and the like, trolley conveyors (also referred to as hanger conveyors) are often employed as means for transporting products and semi-finished products between production lines. According to this trolley conveyor, space within the factory can be used effectively, cargo can be reliably transported without being damaged, and workability and safety can be improved. However, with a trolley conveyor, when loading and unloading loads from other conveyors, it is necessary to lift and lower the loads, making it difficult to automate the loading and unloading process. The large amount of work required during transport has been an obstacle to reducing production costs. For this reason, there is a widespread need for a cargo transfer device that can automatically carry cargo into and out of a trolley conveyor, and that can carry out the loading and unloading operations reliably, quickly, and at relatively low cost.

Conventionally, so-called industrial robots have been used as devices for automatically transferring cargo as described above. The industrial robot will be explained below.

FIG. 1 is an explanatory diagram showing an industrial robot conventionally used as a device for transferring and loading cargo.

As shown in FIG. 1, 1 is an industrial robot installed between a trolley conveyor 2 and a discharge conveyor 3. As shown in FIG. This industrial robot 1 includes a base 4, a support column 5 that is attached to the base 4 and moves up and down as appropriate, and a head member 6 that is rotatably attached to the upper part of the support column 5 and holds an arm 6a so that it can be taken in and out as needed. It consists of The tip of the arm 6a is formed into a wide fork shape so that the load M can be stably placed thereon. On the other hand, the trolley conveyor 2 is connected to an installed trolley guide 7.
and a hanger 8 that is supported and guided by the trolley guide 7 and moves at a predetermined speed while loading the cargo M thereon.
It consists of This hanger 8 has two bottom plates 8.
a, 8b are at a predetermined interval, in the case shown, arm 6
It is provided with an opening long enough to accommodate the tip end of the bag M, and the cargo M is loaded onto the trolley conveyor 2 by supporting both ends of the cargo M with these bottom plates 8a and 8b. On the other hand, the carry-out conveyor 3 consists of two side plates 3a and 3b, and a large number of rolls 3c rotatably held between the side plates 3a and 3b, and is installed at an appropriate angle of inclination.

A gap is formed in this carry-out conveyor 3, and the size of the gap is smaller than the cargo M and the arm 6
It is larger than the tip of a. In such an installation situation, the hanger 8 carrying the cargo M is moved along the trolley guide 7 to the industrial robot 1.
drive towards. When the hanger 8 comes near the industrial robot 1, the industrial robot 1 is activated by the action of a detection device and a control device (not shown).

That is, the arm 6a is placed below the hanger 8 in advance.
When the hanger 8 comes closest, raise the support column 5 and touch the bottom plate 8a.
Insert the tip of the arm 6a between the and the bottom plate 8b,
The load M is supported by the arm 6a. Immediately after that, the arm 6a is retracted to separate the cargo M from the trolley conveyor 2, and the head member 6 is rotated relative to the base 4, so that the tip of the arm 6a carrying the cargo M is placed above the carry-out conveyor 3. Let them come. Thereafter, the support column 5 is lowered to put the tip of the arm 6a into the gap between the carry-out conveyors 3, and the cargo M is supported by the rolls 3c. This cargo M slides down on the carry-out conveyor 3 toward the next process. Industrial robot 1
Thereafter, the support column 5 is raised, the head member 6 is rotated, the arm 6a is further protruded, and the trolley guide 7 comes to rest at its original position. By repeating the above operations, the industrial robot 1 transfers the cargo M from the trolley conveyor 2 to the carry-out conveyor 3.
It operates sequentially to transfer the In this way, the industrial robot 1 can unload the load M and move it to another place without manual intervention, and its operation is precise and reliable.

However, the industrial robot 1 as described above has a problem in that its ability to transfer the load M (hereinafter referred to as transfer ability) is limited due to its operating principle, and it is also expensive.

That is, when loads M are conveyed one after another by the trolley conveyor 2, the industrial robot 1 intermittently moves the arm 6a in and out, rotates it, and moves up and down.
When increasing the transport speed of the load M, the arm 6
It becomes necessary to rotate a at a higher speed. However, when arm 6a is rotated at high speed, arm 6a
There is a risk that the load M on the load a may fly out due to centrifugal force, and therefore there is a limit to the ability of the industrial robot 1 to transfer the load on its own. Since all three operations of taking in and taking out the arm 6a, rotating it, and raising and lowering it are required, the drive system and control system are complicated, and as a result, the industrial robot 1 has the drawback of becoming extremely expensive.

In a slat conveyor that transports slats, there is a payout pin that is held between the slats and is slidable along the side of the slats, and a payout pin that is fixedly provided below the slats and makes contact with the lower part of the payout pin. By providing a guide plate for appropriately sliding the payout pin, the trolley conveyor, which is installed above the slat conveyor and suspends and conveys the load, can be moved by the action of the payout pin and the guide plate. As a result, the cargo is transported while moving onto the slats, and the cargo can be continuously discharged onto the slats.

Further, according to the present invention, by providing the above-mentioned mechanism, the baggage can be continuously delivered from the trolley conveyor, so that the baggage can be transferred more quickly, and the transfer capacity can be improved. It is something that can be done.

Further, according to the present invention, by providing the front payout pin and the rear payout pin as the payout pins, the baggage is pushed at two points, and the baggage can be reliably paid out from the trolley conveyor onto the slat. .

Further, according to the present invention, by providing a dispensing guide plate for sliding the dispensing pin when dispensing the package, and a return guide plate for returning the dispensing pin to the original position after dispensing the package, the dispensing pin can be fixed. The slats act to sequentially discharge the loads, and the simple mechanism allows the loads to be continuously discharged onto the slats one after another.

Further, according to the present invention, a load receiving plate is fixedly attached on the slat near the payout pin at a location not facing the trolley conveyor, and a positioning protrusion is formed at the end of the load receiving plate. By doing so, when transferring cargo from the trolley conveyor to the slat conveyor, the movement of the cargo becomes smooth, and the load is reliably placed on the slat, ensuring that the cargo is placed onto the slat without damaging it. It is something that can be paid out.

Further, according to the present invention, a pair of rotating guide plates are provided at the upstream end of the delivery guide plate in the cargo transport direction, and are brought into contact with the lower part of the delivery pin only when necessary, so that the cargo can be slatted as desired. It can be sent upwards.

Further, according to the present invention, a plurality of the above-mentioned dispensing pins are provided, the dispensing pins are moved by the guide plate in a direction perpendicular to the advancing direction of the dispensing pins, and a slat conveyor for holding the dispensing pins is provided. Match the direction of movement with the trolley conveyor and synchronize the speed of movement of both conveyors.
Furthermore, by making the interval between the payout pins of the slat conveyor and the interval between the hangers of the trolley conveyor the same, and by making the length of the endless chain band of the slat conveyor an integral multiple of the interval between the hangers of the trolley conveyor, The baggage is continuously delivered from the trolley conveyor to the slat conveyor, and even baggage that has been conveyed at high speed can be transferred to the cargo.

Furthermore, according to the present invention, by using the above-mentioned mechanism, cargo can be transferred from the trolley conveyor to the discharge conveyor without using human hands.
It is simple, reliable, and quick, and is effective in reducing costs on the production line. It also has a simple structure because it does not require sophisticated control functions and only requires adding a simple mechanism to a normal slat conveyor. It exhibits excellent effects such as being inexpensive, easy to maintain, and highly reliable.
