Abstract

PURPOSE:To easily deal with the alteration of the length of a drive section for a belt, and enable pallets to be transported with ease at the time of initial erection in the pallet carrying device carrying each pallet holding products to be used for an assembly line. CONSTITUTION:The pallet carrying device is so constituted that a plurality of drive sections 1 each of which has a drive roller 8, a plurality of driven rollers 11 and a belt 12 installed on the drive roller 8 and the driven rollers 11, are joined firmly to a main body section 1 furnished with paired right and left frames 3 and with a plurality of leg sections 13 supporting the frames 3, by fixing bolts 4. Each drive section 1 can be detachably installed onto the main body section 2 by releasing/fastening the fixing bolts 4, the drive block of the belt 12 of the drive section 1 which has been removed, can simply be altered in length, and it is easily transported.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet transfer device for transferring a pallet holding products on an assembly line or the like.

[0002]

2. Description of the Related Art In recent years, assembling, disassembling, and transporting a pallet carrier at the time of initial installation of the assembly line or change of process organization in a pallet carrier that conveys pallets holding products etc. There is a demand for simplification of the above and simplification of the device itself, and an invention having a simple structure has been made (for example, Japanese Patent Laid-Open No. 1-271320).
(See the official gazette).

A conventional pallet conveyor will be described below. As shown in FIG. 3, when the pallet 21 holding products and the like moves in the direction indicated by the white arrow A,
A pair of left and right frames 22 for preventing the pallet 21 from shifting in the direction indicated by the arrow B, a drive roller 24 attached to the frame 22 via a bearing 23, and a drive roller 24 attached to the frame 22 via a bearing 25. Driven roller 26
And a plurality of legs 27 that support the frame 22, and the legs 2
7, a motor 28 disposed on one side of the drive roller 24, a belt 29 circumscribed around the driving roller 24 and the driven roller 26 and shown by a chain line, and a driving force of the motor 28.
Drive belt 30 that is transmitted to the drive roller 24, and the drive force of the motor 28 transmitted to the drive roller 24 is applied to the belt 2
9, the pallet 21 is conveyed in the traveling direction of the belt 29 indicated by the white arrow A by the frictional force of the surface of the belt 29.

[0004]

However, in the above conventional structure, the drive roller 24, the motor 28, and the belt 2 are used.
Since the drive portion such as 9 and the main body portion including the frame 22 and the leg portion 27 are integrally configured, the length of the drive section of the belt 29 is changed to change the length of the drive section of the pallet 21 when the process knitting is changed. There is a problem that processing such as changing the stop position is not easy.

The present invention solves the above-mentioned problems of the prior art, and when the process organization is changed, the length of the belt drive section is changed to change the stopping position of the pallet and the like. Another object of the present invention is to provide a pallet transfer device that can be easily transported during initial installation and relocation of the entire process line.

[0006]

To achieve this object, a pallet conveyor according to the present invention comprises a driving roller supported by a bearing and driven by a motor, a plurality of driven rollers, and a circumscribing outer circumference of the driving roller and the driven roller. A plurality of driving portions having a belt stretched by the above structure are connected to a main body portion having a pair of left and right frames and a plurality of legs supporting the frames by fixing bolts.

[0007]

In this structure, the driving portion and the main body portion are detached by releasing and fastening the fixing bolts, and when the process knitting is changed, the length of the driving section of the belt of the removed driving portion is changed. Becomes

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the drive unit 1 is housed in a pair of left and right frames 3 of the main body 2 and can be detached by releasing and fastening the fixing bolts 4.

The drive unit 1 includes a motor 6 attached to the base plate 5, a drive roller 8 attached to the base plate 5 via a bearing 7, and a drive belt 9 stretched between the motor 6 and the drive roller 8. A plurality of driven rollers 11 mounted on the base plate 5 via bearings 10,
The belt 12 is surrounded by the driving roller 8 and the driven roller 11 and is stretched around the belt 12 and is shown by a chain line. Body 2
Is composed of the frame 3 and a plurality of legs 13 that support the frame 3. Reference numeral 14 in the figure denotes a pallet.

According to the pallet transporting device constructed as described above, the driving force of the motor 6 transmitted to the driving roller 8 is transmitted to the belt 12, and the pallet 14 placed on the belt 12 is transferred to the surface of the belt 12. Is conveyed in the traveling direction of the belt 12 indicated by the white arrow A.

When the process knitting is changed, the fixing bolt 4 is removed, the drive unit 1 is removed from the main body unit 2 as shown in FIG. 2, the position of the driven roller 11 and the length of the belt 12 are adjusted, and then, again. The bolt 1 for fixing the drive unit 1 to the main body 2
The stop position of the pallet 14 can be easily changed by mounting with.

As described above, according to this embodiment, the drive unit 1
The belt 1 has an independent structure in which the main body 2 and the main body 2 are detachable.
It is possible to easily change the stop position of the pallet 14 by changing the length of 2 by removing only the drive unit 1.

Also, during initial installation and relocation of the entire process line, the drive unit 1 moves as a single unit without disassembling, and the main body unit 2 disassembles into the frame 3 and the legs 13 to move. , Easy to carry.

[0015]

As is apparent from the above description, according to the present invention, a driving roller supported by a bearing and driven by a motor, a plurality of driven rollers, and a belt stretched around the driving roller and the driven roller. With a configuration in which a plurality of drive parts having a pair of left and right frames and a plurality of legs supporting the frames are coupled to a main body part by fixing bolts,
Processing such as changing the length of the belt drive section to change the stop position of the pallet when changing the process organization etc. is easy, and it is easy to carry during initial installation or relocation of the entire process line. It is possible to realize an excellent pallet transfer device that can be realized.
