[Industrial applications]

 The present invention relates to a corner conveyor.

[0002]

[Prior Art]

 Conventionally, when an item to be conveyed by a conveyor is bent and sent at a right angle, a group of rollers are provided on a substantially square base in a diagonal direction, and on both sides of the roller group in a direction orthogonal to the forward and backward movement direction of the conveyor. We are actually using a corner conveyor that has a roller group with long entrances and exits, and other rollers that are shortened one after another.

In a conventional corner conveyor, rollers are arranged on a stand, and a geared motor is used for the stand to control the rotation speed of each roller group by using a motor for each roller group. It was what was there.

[0004]

[Problems to be solved by the device]

 The conventional corner conveyor requires a certain height due to the configuration of the motor installed under the table, and cannot be lowered. However, there are places where the height is limited, such as above the ceiling, above the floor, and below the floor, and there are places where the lower ones make it easier to handle the conveyed items, and therefore a conveyor with a thin structure is required.

Recently, low-floor type conveyors are often used in production facilities for tall ones such as corrugated cardboard, woodworking and packaging materials, or in warehouses and stock places, and are used for their transportation and temporary stocking. Has been done. This is because when the conveyor becomes higher, the workability deteriorates or the stock efficiency decreases, so the workability and stock efficiency, which are advantages of the low floor type, are evaluated. No corner conveyor has been proposed for these low floor conveyors.

[0006]

[Means for Solving the Problems] In the present invention, therefore, the entire conveyor can be configured to be low by removing the motor installed at the bottom of the table to raise the overall height, and thus a low floor type conveyor can be obtained. This is to propose a corner conveyor that can be used correspondingly, and can be used even in places where the installation height is limited, such as above the ceiling, above the floor, and below the floor.

[0007] A corner conveyor in which rollers are provided on a substantially square base in a diagonal direction, and rollers are provided on both sides of the rollers in a direction orthogonal to the forward / backward direction of the conveyor, with a long entrance / exit end and other rollers sequentially shortened at appropriate intervals In this case, at least one motor roller is installed on each of the rollers provided on both sides of the roller provided in the diagonal direction, and each roller in the same direction is connected to the motor roller.

【Example】

Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. 1 is a base, the legs 4 which is placed a U-shaped frame body 3 and 31 and the frame body 3, 31 provided substantially at right angles across the one end thereof a foundation 2 is formed in a substantially square shape, a jack It is fixed to the floor 6 etc. by bolts 5, 5, 5, 5 so that the vertical position can be adjusted. The base 1 can also be formed into a square base 2, and the jack bolts 5, 5, ... Can be provided only on the base. The fixing means is not limited to the jack bolt 5, and other fixing means can be used.

Numeral 7 is a roller installed in a diagonal direction of the base 1 by frames 19 and 20 provided on the base 2. One of the rollers uses a motor roller 71 and the other uses a free roller 72. The roller 7 is installed on the base 2, and the motor roller 71 and the free roller 72 are connected to each other by a belt or a chain 11. In order to hang the belt and chain 11, the motor roller 71 and the free roller 72 are provided with a hanging portion 16 such as a V groove or sprocket.

Numeral 8 is an entrance side roller, one end of which is pivotally supported by the frame body 3 and the other end of which is provided close to the roller 7 on the base 2 so as to be supported by the frames 12, 12 ,. The rollers 8 are made longer and shorter in sequence. An appropriate number of the rollers 8 are motor rollers 81, 81, ... And other rollers are free rollers 82, 82 ,. The motor roller 81 and the free roller 82 are connected to each other by belts or chains 13, 13, .... The motor roller 81 and the free roller 82 are provided with the engaging portions 17 such as V grooves and sprockets as described above.

[0011] 9 the exit side roller, one end is pivotally supported by the frame body 31, the inner end frames 14, 14 provided on the base 2 in close proximity to the roller 7, ... it is supported in ~, outwards A long roller is installed. The motor rollers 91, 91, ... Are arranged at appropriate places in the roller 9 , and the other rollers are used as free rollers 92, 92, .. The motor roller 91 and the other free rollers 92, 92 ,. , 15, 15, ... Connected to each other. The belt and the chain 15 are suspended on a suspension portion 18 such as a V groove or a sprocket provided on the motor roller 91 and the free roller 92, respectively.

Each of the motor rollers 71, 81, 91 has a structure in which a motor M is built in, and is rotated by an internal gear via a planet gear rotated by the motor M.

When the rollers 7 , 8 and 9 are supported by the frame 3 or 31 or the frame 19, the shaft ends are supported by the through holes 25, 25, ... Provided in the frame 3 or 31 or the frame 19. Further, the rollers 7 , 8 and 9 are preferably provided with square holes 27 in separate mounting frames 26 so that the shaft ends are fixed in the rotating direction.

It is convenient to connect the motor rollers 71, 81, and 91 to separate inverters 21, 22, and 23, respectively, and change their frequencies. The rotation of the motor rollers 71, 81 and 91 can be reversed.

As a practical example, the inverter 21 connected to the motor roller 81 on the entry side is set to 37 Hz, the inverter 22 connected to the motor roller 71 is set to 33 Hz, and the motor roller 91 on the exit side is set. The inverter 23 connected to is set to 55 Hz.

At that time, each motor roller 71, 81, 91 is rotated at a speed of the ratio. It was found that when the transported object 24 is moved under this condition, the transported object 24 can be transferred smoothly.

Reference numeral 28 denotes a mounting table which is extended from the table 1 and on which inverters 21, 22, 23 are installed. 29 is a traveling side conveyor, which is installed in contact with the outer end of the entrance side roller 8 . An exit side conveyor 30 is installed in contact with the outer end of the exit side roller 9 . Both the entrance side conveyor 29 and the exit side conveyor 30 have the same height as this corner conveyor, and usually a low floor type conveyor is used.

Next, the operation will be described. The rotation speed of the entry side roller 8 is set to be the same as the driving speed of the entry side conveyor 29 by the inverter 22. The rotation speed of the rotation side roller 9 is synchronized with the speed of the exit side conveyor 30 by the inverter 23. However, the speeds of the entrance side roller 8 and the entrance side conveyor 29, and the exit side roller 9 and the exit side conveyor 30 may not be the same.

The ingress roller 8 has its motor rollers 81, 81 controlled by the inverter 21 and is rotated by the set value, and the free rollers 82, 82, ... Similarly, the belts and chains 13, 13 ,. ... are rotated at the same speed. For this reason, even if the conveyed object 24 conveyed by the entrance-side conveyor 29 is placed on the entrance-side roller 8 , it advances at the same speed as the entrance-side conveyor 29.

[0020] Thus, the tip of the transfer material 24, through the entrance side roller 8, reaches the roller 7 provided on oblique to entry side roller 8, the rotation of the rollers 7 by inverter- 22 low It is controlled by rotation. Therefore, the speed of the leading end of the conveyed object 24 is reduced, and the inner side is first placed on the roller 7 and is decelerated, while the rear side is fed at the conventional speed, so that the inner side of the leading end rotates. The transported object 24 is moved and placed in a direction orthogonal to the roller 7 .

At this time, the outer end of the conveyed product 24 is already placed on the exit side roller 9 , and the exit side roller 9 is rotated at a speed 4 to 5 times that of the roller 7 . Then, it is rapidly fed inward, and the conveyed article 24 is rotated inward so that the article 24 is turned in the direction orthogonal to the exit side roller 9 . Then, it is sent to the exit side roller 9 and conveyed by the exit side conveyor 27.

[Effect of the device]

 According to the present invention as described above, the rollers are provided on the substantially square base in a diagonal direction, and the rollers with the entrance / exit end being long and the other ends being sequentially shortened are provided on both sides of the rollers in a direction orthogonal to the moving direction of the conveyor. In the corner conveyor installed in the above, at least one motor roller is installed on each roller installed on both sides of the roller installed in the diagonal direction, and each roller in the same direction is connected to the motor roller. It is possible to construct a roller conveyor with a mechanism that is approximately the diameter of the roller. Therefore, it can be used by connecting with a low floor type conveyor.

Therefore, as a connection corner of a low-floor type conveyor installed in a warehouse or a stock place, it is extremely large as a factory for improving the workability of transportation and storage in those places and a place where the efficiency is improved. Furthermore, it is extremely effective as part of a conveyor in low places such as above the ceiling or under the floor, and its practical effects are remarkable.
