Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an article transporting and unloading device that can selectively transport and simultaneously transport articles of different types, sizes, etc., for example.

As shown in FIGS. 1 and 2, a conventional device of this type moves a walking rail 2 in a circular motion by rotating an eccentric shaft 1 while transporting articles 3, such as cooking rods, in the direction of the arrow shown in the figure.
By pushing up one article 3 at the end of the walking rail by the pushing up actuator 4, the article 3 on the walking rail 2 is brought into engagement with the upper edge of the stopper 5. The article 3 engaged on the stopper 5 is sent to the carriage 6 via the stopper 5 having an inclined upper surface, but since the carriage 5 itself has an arcuate outer shape, the article 3 is moved in the direction of the arrow shown in the figure. It glides and is set horizontally. Here, the push-up actuator 7 performs a push-up operation in the direction of the arrow shown in the figure to push the carriage 6 up to a predetermined position, and then stops.
Next, the horizontal ejecting actuator 8 performs an ejecting operation in the direction of the arrow D shown in the figure to eject the article 3 in the carriage 6 and supply it to the carry-out belt 9.
This delivery belt 9 transports the articles 3 from the carriage 6 to a predetermined location.

However, in the article transfer/unloading device as described above, since the articles 3,... are transferred by one series of walking rails 2, certain types of articles 3,...
If you try to transfer other types of articles 3,... during the transfer, remove all remaining articles 3,... from the walking rail 2, and then start walking the other types of articles 3,... anew. It has to be supplied to the rail 2, which poses problems such as the complexity of the work and the reduction in the efficiency of the transport and unloading work. Also,
The article 3 on the walking rail 2 is carried out by the belt 9
Not only does it require a large number of actuators until the article is delivered to the carriage 6, but also the article 3 from the walking rail 2 is set horizontally in the carriage 6, so the walking rail 2 and the carry-out belt 9 are
The disadvantage is that a lot of space must be left between the two.

The present invention has been developed to eliminate the above-mentioned drawbacks, and is capable of transporting the same or multiple types of goods without replacing them, as well as allowing for accurate selection and transport of the required goods using a small amount of space. The purpose is to provide equipment.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 3 to 8. In these figures, 11 is an article such as a connecting rod having a large end 11a on the upper end and a small end 11b on the lower end. be transported. This transfer rail 1

15b is attached so that it can be pushed out. In addition, two pairs of walking rails 15a-15a, 15b-
Although not shown, at least one rotating eccentric body is in contact with the lower end surface of 15b, and the rotation of this rotating eccentric body causes the two pairs of walking rails 15a-15a, 15b-15b to move counterclockwise. It is configured to move in a circular motion. In other words, walking rails 15a-15a, 15b-15b
is pushed up from the surface of the fixed rail 13 by the rotation of the rotating eccentric body, suspends the articles 11, and moves them forward a predetermined distance by circular motion. ,... are suspended on the fixed rail 13, the transfer paths 14a, 14
A large number of articles 11, . . . are simultaneously advanced by repeating eccentric rotation within b and returning to the original position. A guide 16 is erected on the end side of the two transfer rails 12 with a predetermined gap from the end of the rail 12, and a guide 16 is always provided in the gap. A stopper 18 having a U-shaped upper end is provided for each of the transfer paths 14a and 14b, and is raised by a spring 17 and is pushed down by the carriage when it is lowered, which will be described later. The guide 16 includes a common guide groove 16c extending downward from the upper end side, and a lower end branching from the lower end side of the common guide groove 16c, each of which has a lower end portion connected to each transfer path 14a of the transfer rail 12,
A branch guide groove 16a that matches positionally with 14b,
16b. And the common guide groove 16c
A switching gate 19 is arranged at the intersection of the branch guide grooves 16a and 16b. This switching gate 19 has a function of communicating one of the branch guide grooves 16a and 16b with the common guide groove 16c and closing the remaining branch guide grooves. Note that the switching gate 19 is switched using a hydraulic cylinder, a rotary solenoid, a motor, etc., but the switching control signal may be given manually, for example, or the article 11, It is also possible to automatically issue a signal by detecting the absence of...

Further, endless chains 20a and 20b are provided on both sides of the guide 16, and these endless chains 20a and 20b are made to reciprocate by forward and reverse rotation by a motor or by vertical movement by a cylinder. . 21 indicates a motor or cylinder, and 22 indicates an endless chain 20a, 20.
It is a rotating support body that supports both ends of b. and,
Article 1 is attached to these endless chains 20a and 20b.
Two rods 24, 24 which movably support a carriage 23 carrying the rod 1 are installed at a predetermined distance. As specifically shown in FIG. 5, this carriage 23 has a stopper pressing portion 23a and a walking rail 15a on the front side from both lower sides.
15a or 15b-An upper end curved piece 2 that takes the article 11 supplied from 15b inside and prevents it from falling.
A protruding body 23' with 3b is protruded.

Next, the operation of the article transporting and unloading device configured as above will be explained. First, the walking rails 15a-15a, 15b are rotated by rotating the rotating eccentric body.
-15b in a circular motion counterclockwise. In this state, articles 11, . Both transfer paths 14a, 14b
When using the two transfer paths 14a, 14
Articles 11, . When the articles 11,... are fed to the transfer rail 12 in this way, the walking rails 15a-15a, 15b
-15b pushes up from the surface of the fixed rail 13 as shown by the dotted line in Figure 4 due to circular motion, and the article 1
1,... are suspended and moved forward a predetermined distance, and then sunk down to be suspended on a fixed rail 13. By repeating this process, a large number of articles 11,... are moved forward in an orderly manner. At this time, the switching gate 19 is operated by artificial or automatic means to enable the use of a desired branch guide groove, for example 16a, to close the other branch guide groove 16b, and to close the endless chains 20a, 20b. When the carriage 23 is moved toward the return path side by the cylinder etc. 21, it descends through the common guide groove 16c and the branch guide 16a. When the carriage 23 descends to the vicinity of the stopper 18, the stopper pressing portion 23a of the carriage 23 comes into contact with the stopper 18, thereby pushing the stopper 18 down. When the carriage 23 descends to a predetermined position, that is, the article supply position, and stops, the article 11 at the front end is supplied to the carriage 23 by the circular movement of the walking rails 15a-15a. This carriage 23 has an upper end bent portion 23b on its protrusion 23'.
is formed, so that the article 11 fed from the rails 15a-15a is attached to the upper end curved portion 23b.
Get on it and go inside. In this state, when the endless chains 20a and 20b move forward, the carriage 23 lifts the article 11 while guiding it through the branch guide groove 16a and the common guide groove 16c. And the carriage 23
When the article 11 rotates around the rotary support 22 and tilts slightly as shown in FIG. 8, the article 11 naturally slides down and is transferred to the delivery belt 26. When the carriage 23 moves away from the article supply position, the stopper 18 is pushed up by the spring 17 to prevent the article 11 from falling.

The carriage 23, which has transferred the article 11 to the carry-out belt 26, passes through the same course as the forward path due to the return movement of the endless chains 20a and 20b, pushes up the stopper 18, returns to a predetermined position, and stops.
By repeating such a series of operations, a large number of articles 11, . . . on the transfer path 14a side are sequentially transferred to the transfer belt.

Next, the article 11 is placed artificially or on the transfer path 14a side.
When the switching gate 19 is automatically switched due to the absence of the common guide groove 16c, the carriage 23 passes from the common guide groove 16c to the other branch guide groove 16b on its return trip and stops at a predetermined position. The carriage 23 receives the article 11 on the transfer path 14b and carries it out to the carry-out belt 26 in the same manner as described above. Therefore, by using the two transfer rails 12, the same or different types of articles 11 can be efficiently transported to a predetermined location.

Note that the present invention is not limited to the above embodiments. For example, in the above embodiment, the transfer rail 12
Although the number of transfer paths is two, it may be two or more. Of course, it is necessary to increase the number of branch guides in accordance with the number. Furthermore, the walking rails 15a-15a and 15b-15b may be switched and used as necessary. In addition, the present invention can be modified and implemented in various ways without departing from the gist thereof.

As detailed above, according to the present invention, articles are transferred by moving two transfer rails, so it is possible to store and transfer twice as many articles as compared to conventional devices. Multiple types of items can be transferred alternately. Further, by selecting the branch guide groove using the switching gate, the carriage can be freely set to a desired article supply position, and articles can be selectively carried out in units of a predetermined number. Furthermore, the reciprocating motion allows the carriage to accurately stop at a predetermined position to receive or transport articles. Furthermore, by erecting the guide, it is possible to provide an article transporting and unloading device that can transport a plurality of types of articles to a predetermined location in a small space.
