Abstract

PURPOSE:To prevent the fluctuation of a load carrying platform especially at the time of loading and unloading the material to be carried in an unmanned carrying vehicle on which top surface a load carrying platform is provided through vibration- proof materials, by providing a means to lift up and support the carrying platform only when this operation is required. CONSTITUTION:At the travelling time of an unmanned carrying vehicle, multiple pins T1-T4 are respectively fitted in a car body 1, and a load carrying platform 4 is supported by only vibration-proof materials 6. Consequently, the vibration of the material 3 to be carried can be prevented securely with the work of the vibration-proof materials 6. On the other hand, when the unmanned carrying vehicle stops and loading and unloading of the material 3 to be carried is performed, each pin T1-T4 is respectively raised and the vibration-proof materials 6 are extended to lift up the load carrying platform 4 and support it with each pin T1-T4. As a result, the position of the load carrying platform 4 is not changed when loading and unloading of the material 3 to be carried is performed by a transshipping robot 2, and the material 3 to be carried can be held by the transshipping robot 2 accurately. Consequently, carrying and loading and unloading of the material 3 to be carried with the unmanned carrying vehicle can be thereby performed efficiently.

Description

[Detailed description of the invention] “Industrial Application Field 1 The present invention relates to an automatic guided vehicle equipped with an IIF platform.

[Prior art] A conventional unmanned transport Φ with one 41' unit is configured like a small boat in FIG. , the loading robot 2 automatically travels in the direction 5'' 2 and unloads the load 41. at a predetermined location. Perform work to JIJ the conveyed object 3.

During the unmanned transport, the corpuscle 1 and (':J C7
A vibration isolating material 6 is interposed between the objects 4 and 4 to prevent the conveyed object 3 from vibrating due to the unevenness when there is a depression 1-11 in the direction 5 (for example, unevenness of a grating when traveling in a clean room). He was protected from 1 hit.

[Problems that the invention attempts to solve]

By the way, if a soft spring is used as the vibration isolator inside the ship, the vibration isolating effect will be increased, so if a soft spring is selected for the vibration isolator 6, the effect during vibration of the transported object 3 will be increased. However, if a soft spring is used as the vibration isolator 6, the vibration isolator 6 supports the entire weight of the conveyed object 3 and the loading platform 4.
The vibration isolating material 6 is greatly bent by this weight, and the device of the loading platform 4 changes, making it impossible for the transfer ports 1 and 2 to grasp the transported object 3.

For this reason, in the past, there was a problem in that a soft spring could be used for the vibration isolating material 6, making it impossible to increase the vibration II/J11 effect of the C1 conveyed object 3.

This invention solves the problem of the previous a! It's objective is to provide people carriers.

[Failure to solve the problem]

In order to achieve the above object, the automatic guided vehicle of the present invention is provided with means for lifting and supporting the loading platform, and holding the loading platform only when desired. It was designed to support the body by raising it up.

[Function] During unmanned transportation with the configuration described in -1- below, when loading and unloading the transported objects, when the means for lifting and supporting the front sound is activated, the ribs extend -C4"l ft. is supported, and this <:i f7 cannot be supported by the vibration isolating material.
Supported by the means listed in ii. Therefore, at this time l'l'
Even if the l, ;i2 work is performed, the i device on the loading platform will not change. Also, after completing the above work, j1! (When a heavy load carrying people is traveling, the loading platform can be supported only by the vibration isolating material by releasing the support 1' and the ridges of the loading platform. Therefore, the rolling μ of the vibration isolating material is sufficiently suppressed.) The IL effect is exerted. 1. [Example 1] The present invention will be explained in detail with reference to Examples as shown in Figures 1 (A), (B) and ()\. In addition, in these figures, the configuration equivalent to the conventional one is
Corresponding parts in the figure and the numbers are indicated by 1. ]゛, ~'1゛4 is a bottle formed in a tapered shape with a tapered tip, and the n''i part is shown in 1'1 and 10th (b) on one side of the four corners of 4i7 and 4, respectively. It is fitted into the vehicle body 1 as shown in FIG. Reference numeral 7 denotes four holes into which the upper ends of the bins 'I' and ~'I'4 can be inserted, and are provided on the lower surface of the loading platform 4 at positions facing each of the bins T and ~T 4 . In the normal state, the bins '1'1 to 'I'4 are fitted into the vehicle body 1 so that the tops of the bins do not come into contact with the top surface of the loading platform 4, as shown in FIG. When held up by a screw (not shown) provided inside the body, the upper end of the IZ+ (, ) It is structured to support it.

When the unmanned transport vehicle with the above configuration is running, the bins T, ~'F4 are inserted into the vehicle body 1, and only the vibration isolating material 0 is placed on the loading platform, as shown in Fig. 1 (b). It supports 4.

Therefore, at this time, the vibration-proofing effect of the vibration-proofing material 6 is exhibited, and the transported object 3 hardly vibrates. Next, when this unmanned conveyor arrives at the workstation and unloads the conveyed items 3, the unillustrated bisto door is actuated and the link is extended, and the bins '1'', ~'1
゛4 is the top 1. ．． L, L, the vibration isolating material 6 is extended and the A1'4 unit 4 is raised, and the bin' is raised as shown in Figure 1 ()\).
゛, ~T, supports the loading platform 4. Therefore, even if the transfer robot 2 is used to load and unload the transported objects 3 in this state, the position of the loading platform 4 will not change and the transfer robot 2 will be able to transfer the objects properly. Can grab things. Then, when the work of C1 is finished and the cylinder is compressed by operating screws I and N (not shown), the bottles '1' and ~
'l'4 is inserted into the vehicle body 1, the loading platform 4 is lowered, and as shown in Fig.
In the above embodiment, four tapered bins 'l are provided at opposing positions on the lower surface of the four corners of the front sound 4.
゛~]゛I tried to support the loading platform 4 with 4, but the (i) of the bottle
'Z it'''+1, the number and shape are not limited to these, and as long as it can support loading platform A, other items
The gamma angle is 1°/++, and the number and shape are 14.

Naturally, the present invention can also be applied even if the conveyed articles 3 are loaded and unloaded by a transfer robot provided on the ground-1 side.

[Effects of the Invention-1 As explained in 1 above, during unmanned transport according to the present invention, when loading and unloading the transported objects, a means for holding and supporting the cargo platform is provided, so that the following Identifying excellent larvae 3, ■During the loading and unloading work of conveyed objects, the position of 1=:f will not change, so that the moving robot, Soto, can grasp the conveyed objects accurately. Became.

■Since a soft spring can be used as the vibration isolating material, it is now possible to see at a glance the vibration damping IL effect of conveyed objects during unmanned transportation. .
