Abstract

PROBLEM TO BE SOLVED: To solve the problem such that when width and length of a frame, a mounting pitch and tire width of a caster are taken into consideration and a safety plan is taken into consideration in assembly of a rack product, taking of a strong fixing method is inevitable when weight of the product is intended to be supported by only a lower surface, causing to increase weight of each pallet at a high cost, and for preparation necessary of an exclusive use pallet classified by a kind, an enormous cost of equipment is required, in addition application of new kinds of machine is difficult, causing a delay in taking a counter measure. SOLUTION: A mechanism, fixing a frame bottom surface and upper surface interposed of a product to make the condition left as it is liftable and rotatable, is applied. Accordingly necessity for an exclusive use pallet is eliminated, safety assembly capable of corresponding to many kinds of product can be performed, and increasing of a speed for corresponding to new kinds of machine can be attained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product having a rack and a housing structure, and particularly to a heavy product.

[0002]

2. Description of the Related Art Conventionally, it has been necessary to assemble a rack and a housing structure product so that the work can be easily performed by transferring the product to a plate provided with a frame guide and stoppers / fixtures on a lifter having a rotating mechanism. The work was performed by rotating and moving up and down accordingly. Also, as described in Japanese Patent Application No. 8-334218, there is known a method of assembling using a transport device in which a product is seated from below and a transport device which suspends and supports the product above the transport device.

[0003]

However, in the conventional method, when assembling various kinds of products, considering the width and length of the frame, the mounting pitch of the casters and the width of the tires, and considering the safety aspect, the weight of the product is reduced only to the lower surface. If they are to be supported by a pallet, a rigid fixing method must be adopted, so that each pallet is heavy and expensive, and it is necessary to prepare a dedicated pallet for each type, so that the equipment cost becomes enormous. In addition, there is a problem that it is difficult to apply a new model and the response is delayed.

[0004] It is an object of the present invention to solve the above-mentioned problems and to provide a highly safe ascending and descending assembly facility which can be easily applied to various kinds.

[0005]

In order to achieve the above object, according to the present invention, as shown in FIG. 1, there is provided a mechanism in which the bottom and top surfaces of a product frame are sandwiched and fixed, and can be moved up and down and rotated in that state.

[0006]

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

FIG. 1 is a side view of a lifting assembly machine main body according to the present invention, FIG. 2 is a side view showing the operation of the lifting assembly machine, and FIG. 3 is a schematic perspective view of a rack product assembly line using the lifting assembly machine. I have.

Next, the operation will be described.

First, the lift assembly machine is all lowered, and the upper surface of the transport rail 12 and the upper surface of the caster guide 11 of the lift assembly machine are aligned. Then, the rack product frame 1 is carried into the carry-in lifter 15, positioned at a predetermined position, and the carry-in lifter 11 is raised to align the upper surface of the carry-in lifter 15 with the upper surface of the transport rail 12 adjacent thereto. Then, the frame 1 is manually conveyed and moved to the center of the caster guide 11 of the elevating assembly machine as shown in FIG.
Bottom plate 3 equipped with rotation mechanism by switch 4
Is raised by the cylinder 2 to push up the bottom of the frame and stop at a position where the bottom of the caster is higher than the height of the caster guide 11 as shown in FIG. 2B. Grips the upper surface of the frame. If necessary, as shown in FIG. 2 (C), the lifting arm 7 and the top plate 5 attached thereto are driven up by the driving of the gear cylinder 6 to facilitate the assembling operation. And the top plate 5 rotate simultaneously to rotate the rack. When the assembling work is completed and the rack is lowered by the switch, the positioning pin 9 attached to the base is inserted into the positioning provided on the lifting arm 7 and the bottom plate 3 and the top plate are kept in a state where the parallelism of the lifting arm 7 is maintained. Release 5.

Then, the rack is manually conveyed, moved from the conveying rail 12 to the discharge lifter 13 and positioned at a predetermined position, and then the discharge lifter is lowered to discharge the rack out of the line.

In the discharging operation, when the unit is incorporated in a rack product and the weight becomes heavy, the conveying force increases, and it is very manual and dangerous. For this reason, in this automatic assembly line, a transfer mechanism is provided at the bottom of the elevating assembly machine to enable automatic discharge.

As shown in FIG. 4, the discharging mechanism includes a rotating motor 20 and a part of a chain 22 attached to a gear 21 at the bottom of the elevating assembly machine. The rotation motor 20 is driven by a start switch, the chain 22 and the arm 23 are operated to follow the rotation motor and press the bottom side surface of the frame, and the rack is moved for a certain period of time to move the rack and automatically discharge. Perform the operation. At this time, when there is no mounting space and the power of the rotary motor 20 is small, a method of manually supporting and discharging at the same time as driving may be used.

[0013]

According to the present invention, it is possible to assemble safely without requiring a dedicated pallet and to cope with various kinds, and to speed up the response to a new model.
