Description

[Detailed Description of the Invention] The present invention involves unloading the respective members transported by two transport devices to the same location and integrating them by welding or the like, or temporarily assembling them before integration. The present invention relates to transport equipment that can be used for unloading and unloading.

Conventionally, this type of conveyance equipment has been used, for example, as seen in Japanese Patent Publication No. 47-46986, in which a side body is suspended and conveyed using a hanger, is received by a side body carrying means, is lowered, and then is placed on a receiving post. The rear waist carried in is placed on the floor by the rear waist carrying means provided between the hanger and the receiving post. A system is provided in which the next floor can be carried in using this shuttle bar.

According to this conventional method, the floor brought in by a shuttle bar is first passed to a receiving post, then joined, received again by the shuttle bar, and then transported to the next process, so the delivery cycle via the shuttle bar is This reduces overall efficiency and complicates control.

An object of the present invention is to provide a transport facility that can be unloaded without being transferred to a transport means after integration such as welding or temporary assembly.

In order to achieve the above object, the present invention provides a conveying facility that can freely unload cargo, and includes a hanging conveying device for suspending and conveying the first member, and a hanging conveying device disposed below the hanging conveying device so that the conveying direction is the same. a trolley-type conveyance device that supports and conveys the second member; a first member delivery device disposed at an appropriate location on the conveyance path of both conveyance devices;
A welding cart that can be freely stopped is provided on the side of the first member delivery device and below the cart-type transfer device, and the cart-type transfer device is connected to the cart, an elevating platform attached below the cart, and a and a second member clamping device attached to a stand, and the first member delivery device is configured with an elevating frame guided by pillars erected on the sides of both conveyance paths, and a lifting frame that is attached to the elevating frame and conveyed. It consists of a movable frame that can move toward and away from the path, and a first member clamping device attached to the movable frame.

According to the configuration of the present invention, the first member transported by the hanging transport device can be unloaded by using the first member clamping device on the movable frame that is rising and moving toward the movable frame, and then the first member can be unloaded by the first member clamping device. Separation movement, descending movement,
The second member can be moved onto the welding cart for integral formation by the approaching movement, and the second member transported by the cart-type conveyance device can be moved onto the welding cart by the lowering of the lifting platform. Unloading both parts can be done easily. After integral formation, it can be transported to the next process together with the welding cart.

The first
It consists of member clamping devices 35A, 35B, and both first member clamping devices 35A, 35B are
Each of the clamp pieces 36A, 36B includes a plurality of clamp pieces 36A, 36B, and DC servo motors 37A, 37B that operate some or all of the clamp pieces 36A, 36B. 38 is a welding cart, and a holding jig 39 is provided on the upper part of the welding cart. side panel 6
A, 6B after opening the clamp pieces 36A, 36B,
The clamp pieces 36A, 36B have built-in pushing devices that tilt inward according to the vehicle type.

The action will be explained below. The trolley device 3, which has side panels 6A and 6B suspended and supported by a pair of left and right hanger devices 5A and 5B, is stopped at a first member delivery device 26. At this time, lifting frame 2
9A and 29B are rising, and the movable frame 33
Since the panels A and 33B are spaced apart from each other (see the imaginary lines in FIG. 1), the side panels 6A and 6B can be inserted without any problem. Next, the movable frame 33A,
33B relative to each other to bring the clamp pieces 36A and 36B into positions where they can be clamped, as shown by solid lines in FIG. And DC servo motor 37A,
37B to actuate each clamp piece 36A, 36B, and then move the side panels 6A, 6B to the movable frame 3.
Clamp on the 3A and 33B sides. After clamping, the movable frames 33A, 33B are moved closer to each other, and the side panels 6A, 6B are moved forward and removed from the hanger devices 5A, 5B as shown by the imaginary line A in FIG. Thereafter, the trolley device 3 is moved to escape from the first member delivery device 26. During such work,
Alternatively, the cart 1 is formed by clamping the roof 25 with the second member clamping device 18 before and after the work.
2 travels and stops at the first member transfer device 26. Therefore, the side panel 6
A and 6B are separated from each other as shown by the imaginary line B in FIG. 1 along with the movable frames 33A and 33B, and then lowered together with the elevating frames 29A and 29B so that they collide with the second member clamping device 18. Instead, it can be placed in the lower position as shown in phantom line C in FIG. Next, they are moved closer to each other and set on the jig 39 of the welding cart 38 as shown in phantom line D in FIG.
After releasing the clamp, the first member clamping devices 35A and 35B are moved away from each other. After that, the elevator platform 13 is lowered to make the roof 25 correspond to both side panels 6A and 6B as shown by the imaginary line E in FIG. . Next, with the lifting platform 13 raised, the trolley 12 is moved to the roof receiving position. Also, the side panel 6 integrally formed on the welding cart 38
A, 6B and the roof 25 are attached to this welding truck 3.
8, the welding cart 38 is carried out to the next process, and a new empty welding cart 38 is carried in.

According to the present invention having the above configuration, the following effects can be expected. In other words, since the trolley-type transport device is arranged below the hanging transport device so that the transport direction is the same, both transport devices can be arranged compactly by reducing the two-dimensional installation space (area). be able to. Further, the first member transported by the hanging transport device can be unloaded onto the movable frame which is rising and moving toward the movable frame via the first member clamping device, and the subsequent movement of the movable frame away from the movable frame,
It can be moved onto the welding cart that performs integrated formation by descending and approaching movements, and furthermore, the second member transported by the cart-type conveyance device is moved onto the welding cart by lowering the lifting platform. Therefore, the unloading work of both members can be easily performed.
After integral formation, it can be transported to the next process together with a welding cart efficiently and with simple control.
