However, conventional transfer tables such as maintenance tables are required to have sufficient rigidity to allow mounting of processing modules, resulting in a large and heavy structure. For example, the transfer table 100 of FIG. 6 conventionally used by the present applicant has a weight of 300 kg because it carries a processing module weighing more than 2 tons. Therefore, in order to carry the transfer table 100 to a distant factory, working equipment such as a crane and a forklift and a truck for transportation are required, and the transportation work has become large-scale. In addition, since the large transfer table 100 is not usually used, a large storage space is required.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a transfer table and a transfer structure for processing modules that are easy to handle, in order to solve the above problems.

A transfer table according to one aspect of the present invention includes two rail members having extension rails connected to rails fixed on a base and a frame structure that supports the rail members at two points in the longitudinal direction. and one or more connecting members connecting the supporting members, the rail member, the supporting member, and the connecting member are assembled by fastening bolts, and the extension is connected to the rail. The front wheels or rear wheels of the working machine that has moved on the rails on the base are transferred onto the rails.

In another aspect of the present invention, there is provided a processing module transfer structure in which processing modules having working machines mounted on a movable bed equipped with wheels that move along rails fixed on a base are arranged adjacent to each other. A transfer structure for the processing module in a machine line, comprising two rail members provided with extension rails, two support members of a frame structure supporting the rail members at two locations in the longitudinal direction, and One or two or more connecting members that connect the members each have a transfer table assembled by fastening bolts, and have a rail fixed on the base and an extension rail that constitutes the transfer table. The front wheels or rear wheels of the processing module that are connected and moved on the base along the rails are transferred to the extension rails.

According to the above configuration, since the rail member, the support member, and the connecting member are assembled by fastening bolts, the transfer table can be easily transported and assembled and disassembled on site. Since the front wheels or the rear wheels of the work machine are mounted on the extended rails, even a light-structured transfer table can support the processing module.

It is the perspective view which showed the transfer structure of a processing module. FIG. 10 is a perspective view showing an assembled state of the transfer table on the rear side; Fig. 10 is a perspective view showing an assembled state of the transfer table on the front side; FIG. 4 is a side view of a state in which two processing modules on the base are moved back and forth; It is a front view showing a processing machine line. FIG. 4 is a perspective view showing a processing module that constitutes a processing machine line;

An embodiment of a transfer table and a transfer structure of processing modules according to the present invention will be described below with reference to the drawings. First, FIG. 5 is a front view showing a processing machine line. In the processing machine line 1, various processing modules 2 in which machine tools and the like are modularized are arranged in the body width direction. Specifically, a workpiece loading module is installed on the right end of the drawing, and various processing modules 2 such as lathes, machining centers, and inspection machines are installed between the work ejection module that is the workpiece loading section on the left end of the drawing. is set up.

A front cover 203 that can be opened and closed is formed on the front portion of the exterior cover 201. As shown in FIG. It is configured. 6 is a perspective view showing the processing module 2 that constitutes the processing machine line 1. As shown in FIG. Here, the longitudinal direction of the machining module 2 will be described as the Z-axis direction, the vertical direction of the machine body as the X-axis direction, and the width direction of the machine body as the Y-axis direction.

The processing machine line 1 is arranged in a state in which adjacent processing modules 2 are close to each other. The processing modules 2 are designed to be small in width, and the adjacent modules are arranged close to each other, so that the processing machine line 1 as a whole has a compact configuration. Such a processing module 2 has a structure capable of moving forward and backward along rails 301 fixed to the upper portion of the base 3 . Therefore, in the machining module 2, a working machine body such as a lathe or a machining center is assembled on a movable bed 210 having wheels.

In the processing machine line 1, the processing module 2 is pulled forward or backward to a position where the work can be performed when parts are replaced or maintenance is performed on the processing module 2. As shown in FIG. At that time, a transfer carriage 100 shown in FIG. 6 has been used until now. The transfer carriage 100 can load one processing module 2 as it is, is long in the front-rear direction, and has rigidity capable of loading even a processing module 2 exceeding 2 tons. Therefore, as described in the above problem, when the transfer carriage 100 must be transported, the transport work becomes large-scale. Moreover, since it is not normally used, there is a problem that a large storage space is required.

Therefore, the present embodiment provides a transfer table that is easy to handle in terms of transportation and storage. FIG. 1 is a perspective view showing a transfer structure of a processing module 2 in which the transfer table is attached to a base 3. As shown in FIG. Two processing modules 2 can be mounted on the base 3 that constitutes the processing machine line 1, and two sets of rails 301 are fixed to the upper portion thereof in the front-rear direction. The transfer tables 5 and 6 of this embodiment are configured to be connected to different sets of rails in order to pull out the processing modules 2 forward and backward. The transfer table 5 moves the processing module 2 backward, and the transfer table 6 moves it forward. Both have the same basic configuration, but have different shapes depending on the structure of the machine tool configured as the machining module 2 .

FIG. 2 is a perspective view showing an assembled state of the transfer table 5. As shown in FIG. The transfer table 5 has a structure in which a plurality of members can be assembled by bolting, as shown in the figure, and can be made small by disassembling.

The leg members 21 and 22 are provided with adjusters capable of height adjustment. The transfer table 5 is configured such that when the processing module 2 is moved backward, the rear wheel 211 of the movable bed 210 is positioned corresponding to the leg members 21 and 22 as shown in FIG. 4 is a side view of the state in which the two processing modules 2 on the base 3 are moved back and forth.

The reason why the rear wheel 211 is aligned with the leg members 21 and 22 is to support the load of the processing module 2 with the leg members 21 and 22. Since the width of the transfer table 5 is larger than the rail interval, Although the wheels 211 on one of the left and right sides are positioned directly below the leg member 21 , the other wheel 211 is positioned in the center of the lateral beam member 23 . Therefore, in the present embodiment, the supporting member 11 is configured to have the illustrated shape so that the load is transmitted to the leg member 22 . That is, the leg member 22 is made shorter than the leg member 21, the intermediate member 24 is erected in the center of the horizontal beam member 23, the short horizontal beam member 25 is connected between the intermediate member 24 and the leg member 21, and the short horizontal beam. A diagonal member 26 is connected between the member 25 and the leg member 22 .

It has a structure. The short horizontal beam member 25 has a length matching the wheel width, that is, the rail width of the processing module 2, and mounting metal fittings 27 having screw holes are joined to both ends thereof. The rail member 12 comprises a base member 28 made of square steel pipe, a mounting plate 29 having a screw hole formed thereon, and an extension rail 31 bolted thereon to form a rail member 12 . Mounting metal fittings 32 each having a bolt hole are joined to the lower surfaces of both ends of the rail member 12, and are fixed to the mounting metal fittings 27 by bolting.

The rail member 12 has an extension rail 31 that extends longer than one end of the base member 28, and a mounting bracket 33 that is connected to the rail 301 side by bolting is fixed to the same end. At the other end of the rail member 12, the extension rail 31 and the end of the base member 28 are aligned, and the end surface of the base member 28 is joined with a stopper 34 serving as a wheel stop. By the way, the transfer table 5 is capable of reversing the mounting direction of the rail members 12 so as to correspond to the two sets of rails 301 of the base 3 . Therefore, the transfer table 5 with the rail members 12 assembled in the direction shown in FIG.

Next, FIG. 3 is a perspective view showing an assembled state of the transfer table 6. As shown in FIG. The transfer table 6 also has a structure in which a plurality of members can be assembled by bolting, and can be made small by disassembling. As shown in FIG. 1, the processing machine line 1 has a work transfer device mounted on the front part of the base 3, and an articulated robot arm 8 that can move in the transfer space 4 in the machine width direction (Y-axis direction). It's becoming Therefore, the transfer table 6 is configured with the width of one set of rails 301 so that it can be arranged even next to such an articulated robot arm 8 .

The transfer table 6 has support members 41 and 42 having a frame structure, two rail members 43, and a connection plate 44 that connects the support members 41 and 42, which are fastened together with a plurality of bolts. there is When the transfer table 6 is attached, the support member 41 is positioned outside the transfer space 4 and the support member 42 is positioned inside. Therefore, the distance between the two upright leg members 51 with adjusters is different. The outer support member 41 has a space between the leg members 51 that is equal to the width of the wheel, that is, the rail width, so as to directly support the load of the processing module 2 . They are narrowed inward toward each other by their duty.

The support members 41 and 42 have a pair of leg members 51 each having a pair of leg members 51 with a lateral beam member 52 joined to their upper end faces and lateral beam plates 53 and 54 joined to their lower end faces. The leg member 51, the lateral beam member 52 and the lateral beam plates 53 and 54 are rectangular steel pipes, which are welded together to form a frame structure as shown. Mounting metal fittings 55 having screw holes are joined to both ends of the horizontal beam member 52, and the rail member 43 is fixed thereto by bolting. The rail member 43 has the same structure as the transfer table 5. A mounting plate 62 having a screw hole formed in a square steel pipe base member 61 is joined to the upper surface, and an extension rail 63 is integrated therewith by bolting. ing.

Mounting metal fittings 64 are joined to the lower surfaces of both ends of the rail member 43 , and bolt holes are formed in the mounting metal fittings 64 through which bolts to be screwed with the mounting metal fittings 55 are passed. The rail member 43 has an extension rail 63 that extends longer than one end of the base member 61, and the projecting portion of the extension rail 63 is bolted to the base side. In the rail member 43, the extension rail 63 and the end of the base member 61 are aligned on the side of the support member 41, and the end face of the base member 61 is joined with a stopper 56 serving as a wheel stopper. The support member 42 is configured such that a fixing bracket 56 is bolted to the pair of leg members 51 and is bolted to the base-side mounting portion via the fixing bracket 56 .

The transfer tables 5 and 6 are disassembled into respective parts as shown in FIGS. 2 and 3 when not in use and stored, and the bolts are held in a state of being screwed into the screw holes of the corresponding parts. Although the transfer table 6 in FIG. 3 shows the rail members 43 in a disassembled state, it is stored integrally as the rail members 43 like the transfer table 5 . Then, when moving to the maintenance site, a push trolley or the like is used while the transfer tables 5 and 6 are disassembled into a plurality of parts, and they are placed on a transport vehicle and transported. At the maintenance site, the transfer tables 5 and 6 are assembled integrally by arranging the parts as shown in FIGS. 2 and 3 and tightening the bolts after the bolts held by the parts are removed. .

The transfer tables 5 and 6 are arranged on the front and rear sides of the base 3, as shown in FIG. Then, of the plurality of processing modules 2 aligned in the width direction as shown in FIG. 5, the corresponding two processing modules 2 are pulled out backward or forward as shown in FIG. To make it easier to understand, the state in which two machines are moved at the same time is shown .

In the processing module 2 that has moved backward, the front wheels 211F remain on the legs 701 that support the rails 301, and the rear wheels 211R rest on the support members 11 of the transfer table 5.

FIG. 3 is attached to the rail member 43 in order to position the front wheel 211F at that position.

Therefore, the transfer tables 5 and 6 can pull out the processing module 2 backward or forward to a position where work such as maintenance can be performed. Each of the transfer tables 5 and 6 has a total weight of about 25 kg, and even the support member 11, which is the heaviest component, weighs about 7 kg. Therefore, the transfer tables 5 and 6 can be disassembled and carried by one worker without using a crane or the like, and can be easily assembled and disassembled.

In addition, the transfer structure of this embodiment is designed to move the processing module 2 to the transfer tables 5 and 6 while leaving the processing module 2 on the highly rigid base 3 when pulling out the processing module from the processing machine line 1 . By moving the adjacent processing modules 2 alternately forward and backward, a work space for one unit can be created without pulling out all of them, and work such as maintenance and parts replacement for the processing modules 2 can be performed. become.

The wheels 211 of the transfer tables 5 and 6 are positioned directly above the leg members 21 and 51 , so that the load of the processing module 2 can be directly received by the leg members 21 and 51 . In addition, the leg member 22 is not located directly under the wheel 211 and cannot directly receive the load, but the load applied to the intermediate member 24 receives a large component force in the vertical direction via the diagonal member 26 . be able to. Since the leg members 21 , 22 , 51 of the transfer tables 5 and 6 receive the load in this manner, the transfer tables 5 and 6 can support the processing module 2 even with a lightweight structure.
