Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement of a vertical conveyance sorting device for articles.

[Conventional technology]

As a conventional vertical conveyance device for articles, for example, as shown in Japanese Utility Model Publication No. 49-27992,
One example is one in which two vertical endless belt conveyors are provided facing each other, parts of the belts of both belt conveyors are brought close to each other, and articles are sandwiched between the belts and conveyed in a substantially vertical direction. Although this type of vertical article conveying device has a conveying function, it does not have a function of sorting articles to several unloading positions on the article delivery side.

Furthermore, although the vertical conveyance device disclosed in Japanese Patent Application Laid-open No. 56-155151 has the function of sorting articles to several unloading positions, it has the drawback that the entire device is quite complex. Ta.

[Problem that the invention attempts to solve]

This device is an improvement on the conventional device described above, and by adding a simple mechanism to one of the two vertical endless belt conveyors, articles can be unloaded in multiple vertical directions. This was proposed with the aim of making it possible to easily and arbitrarily sort by location.

[Means for solving problems]

The vertical conveyance sorting device for articles of this invention differs from the above-mentioned conventional vertical conveyance device in that the length of one belt conveyor provided between the fixed frame body and the movable frame body can be expanded and contracted together with the belt at one end thereof. At the same time, the belt is maintained in a tensioned state by wrapping it around rollers provided on a fixed frame body and rollers provided on a movable frame body, so that the length of the belt adjacent portion can be varied, and the belt can be installed in multiple stages in the vertical direction. The article is characterized in that the article can be unloaded at a desired one of the unloading positions.

This invention will be explained below based on embodiments shown in the drawings.

1 is a vertically shaped first endless belt conveyor, 2 is a second endless belt conveyor provided opposite to it, and both belt conveyors 1 and 2 are provided on a cart 3. Parts of the endless belts 1a, 2a of both belt conveyors 1, 2 are placed close to each other along the conveyance direction of the article M shown by the arrow P, and the article M is sandwiched between the belt proximal portions 1b, 2b. It is designed so that it can be moved upward. Therefore, the belt conveyors 1, 2 are driven such that their respective belt proximal portions 1b, 2b move in the same direction in synchronization.

The belt 1a of the first belt conveyor 1 is
Guided by a known frame (not shown) or a pulley, roller, or guide plate supported by the framework,
It is circularly driven by a motor or other drive device 4 fixed to a frame or the like. This endless belt 1a is
In order to be able to wrap the article M when it is sandwiched between the endless belt 1b and the other endless belt 1b (see Figure 1), it is preferable to use a material that is flexible and highly elastic. Of course, a flat belt can be used.

The endless belt 2a of the second belt conveyor 2 is
A lower fixed frame 5 installed on the trolley 3 and an upper movable frame 5 movably attached to the frame 5
A and an auxiliary frame fixed to the trolley 3 (not shown)
It is guided by pulleys, rollers 6, 6a, 6b, or guide plates provided on the carriage 3, and is driven in circulation by a motor or other drive device 7 provided on the truck 3. In FIG. 1, symbols 2c and 2
d shows an article receiving section and a sending section, respectively, which are horizontally protruded from the main body portion of the second belt conveyor 2.

The fixed frame 5 in the belt conveyor 2
The movable frame 5a is formed into a cylindrical shape, for example, and moves along a guide portion (not shown) provided inside the movable frame 5a.
is slidably inserted. Reference numeral 8 denotes an actuating device for extending and contracting the movable frame 5a relative to the fixed frame 5, and the illustrated example telescopic actuating device 8 includes a sprocket 8a,
8b, an endless chain 8b stretched across the sprockets 8a, 8a, and a motor or other drive device 8c for driving the chain 8b.
They are connected by pin 9 through the upper bracket.
The telescopic actuating device is not limited to the one shown in the drawings, but any device that can move the movable frame up and down, such as a piston cylinder device, can be used. The position shown by the solid line in FIG. 1 is the state in which the movable frame 5a is extended to the top with respect to the fixed frame 5, but if the chain 8b of the telescopic actuating device 8 is rotated in the R direction, The movable frame 5a is contracted relative to the fixed frame 5, and the entire belt conveyor 2 can be contracted, for example, to the closed position indicated by the two-dot chain line.
At this time, the belt 2a has a surplus part in its length, but the surplus part is removed from the fixed frame 5.
When the belt 2a is driven, the belt 2a is bent and absorbed by a roller 6a provided at the top of the movable frame 5a and a roller 6b provided at the bottom of the movable frame 5a so as to be adjacent to the roller 6a when the belt 2a is driven. It is automatically maintained at a certain tension. The pulleys, rollers 6, 6a, etc. on the fixed frame 5 and the pulleys, rollers 6, 6b, etc. on the movable frame 5a are provided so that they do not interfere with each other when the movable frame 5 expands and contracts. Of course this is true.

Each part of the device of this invention described above, that is, the entire device is installed on a movable truck 3, and the truck 3 is configured to be able to move laterally on rails 10. 11 connects the trolley 3 to the sprocket 11
a, a motor or other drive device for automatically driving via a transmission mechanism such as a chain 11b.

[Effect]

Next, the operation of this invention will be explained. 1st
To explain with reference to the figure, the article M supplied to the article receiving section 2c is conveyed upward while being held between the belt proximal portions 1b and 2b of the belt conveyors 1 and 2, as shown by the arrow P. 1a and 2a are released at separate positions and reach the article delivery section 2d, where unloading positions A ₁ , A ₂ ...A _o are provided in multiple stages in the vertical direction.
The decision will be given to one of the following. In the illustrated example,
_Although an example is shown in which a conveyance means such as a roller conveyor is installed at each unloading position A ₁ , A ₂ .

In FIG. 1, the second belt conveyor 2 indicated by a solid line is in the most extended state, and in this state the article M is delivered to the topmost unloading position _A1 . When the telescopic actuating device 8 is operated by pressing the operation button corresponding to position A _i , the chain 8b of the device 8 rotates in the direction of arrow R and stops at a predetermined position, and is therefore connected to the chain 8b. The movable frame body 5 of the second belt conveyor 2
Guided by the fixed frame 5, a also descends by the same distance as the moving distance of the chain 8b and stops, and the article delivery section 2d corresponds to the position indicated by the two-dot chain line, that is, the desired unloading position _Ai . can be displaced to the desired position. During this time, the length of the second belt conveyor 2 will be shortened, but the excess length of the belt 2a will be reduced by the rollers 6a provided at the top of the fixed frame 5.
The belt 2a is flexed and absorbed by the roller 6b provided at the bottom of the movable frame 5a, and the belt 2a is continuously maintained at an appropriate tension state, so that the first and second belt conveyors 1 and 2 are driven again. If so, the articles M can be sorted to the desired position, that is, the unloading position A _i .

Even when the chain 8b of the telescopic actuating device 8 is rotated in the direction of the arrow Q to extend the movable frame 5a, the position of the article delivery portion 2d can be changed by the same action as described above. According to the device of
This means that the articles M can be distributed to arbitrary unloading positions A ₁ , A ₂ . . . A _o .

FIG. 2 clearly shows a case where unloading positions A ₁ -A _o and equivalent unloading positions B _{1 -o} , C _{1 -o} , . In this case, the cart 3 is driven to move from one unloading position A ₁ to o to other unloading positions B _{1 to o} , C _{1 to o} , . . . along the rail 10. Thus, the entire vertical conveying and sorting device can be displaced laterally, so that the distribution of articles M at the above-mentioned unloading positions A _1-o as well as at all other unloading positions B _1-o , The articles M can also be arbitrarily sorted into C _{1 to} o, . . . .

In the illustrated example, the article M is conveyed from the bottom to the top on the endless belt conveyors 1 and 2, but the device of the present invention can be designed to convey the article from the top to the bottom. Of course.

[Effect of idea]

According to the vertical conveyance sorting device of this invention described above, by providing a relatively simple mechanism to one of the two vertical endless belt conveyors, articles can be unloaded in multiple vertical directions. It is possible to easily and arbitrarily sort articles according to their positions, and this has the effect of significantly increasing the efficiency of conveyance processing work of articles.
