Problems solved by technology

Therefore, the number of linear motors for feeding the workpiece increases, the structure becomes complicated, and the manufacturing cost increases
[0020] As described above, even if the servo motor or other countermeasures are used, the effect of simplification of the structure is not sufficient, so there is a high demand for further simplification of the structure and cost reduction.

Embodiment approach 1

[0095] The first embodiment of the present invention will be described.

[0096] figure 1 A front view of the continuous automatic press (press machine) 1 according to Embodiment 1 of the present invention is shown in FIG. figure 2 It is a perspective view of a continuous automatic press (work transfer device) 41.

[0097] First, use figure 1 The overall configuration of the continuous automatic press 1 as the first embodiment of the present invention will be described.

[0098] The continuous automatic press 1 consists of a press main body 1A composed of a machine tool 23, a support column 21, a beam 20, and a slider 22, a mold 11 equipped with an upper mold 12 and a lower mold 13, a movable table 30, and a continuous automatic feeder 41 constitute. In addition, a general-purpose robot 7 for carrying out the workpiece is provided on the downstream side of the continuous automatic press 1.

[0099] Under the floor (FL), there is a machine tool 23 that becomes the base of the c...

Embodiment approach 2

[0147] Next, the second embodiment of the present invention will be described. In addition, the same symbols are used for the same parts as those explained in the first embodiment, and the explanation will be omitted. The continuous automatic feeder 41A of the second embodiment uses one linear motor 53A for feeding horizontally installed on the rod 14 to move a plurality of feeding carriers 52 connected to each other for feeding. The mode 1 continuous automatic feeder 41 is different.

[0148] Figure 13 There is shown a perspective view of a continuous automatic feeder 41A according to Embodiment 2 of the present invention. As that Figure 13 As shown, in the second embodiment, a moving member 58 is provided on the fixed rod 141 at one end of the rod 14. The moving member 58 is arranged between the linear motor 57 and the upper surface of the rod 14 so as to move freely in the feeding direction. guide. The feeding drive mechanism of the present invention is constituted by provid...

Embodiment approach 3

[0158] Next, the third embodiment of the present invention will be described. In addition, the same reference numerals are used for the same parts as those described in the first and second embodiments, and the description thereof will be omitted. In the third embodiment, the feed carrier 52 of the first embodiment is driven by a servo motor, and is different from the first embodiment in this point.

[0159] Figure 14 It is a perspective view showing a part of the continuous automatic feeder 41B of the third embodiment. As that Figure 14 As shown, the rod 14AA is the same as in the first embodiment. A pair of rods 14AA are provided in parallel with the workpiece conveying direction. A plurality of feed carriers 52B are provided on a pair of feed rails 51, 51 on the upper surface of the rod 14AA, and are respectively provided. Can be configured separately and mobile. and, Figure 14 Although one feed carrier 52B is shown in, any number can be set as needed.

[0160] The feed car...

Abstract

A work carrying device of a pressing machine, comprising a transfer feeder (41) having a lift / clamp device (80) moving a bar (14) in the lift direction and the clamp direction, a plurality of feed carriers (52) installed on the bar (14), and feeding linear motors (53) driving the feed carriers (52) in the feed direction. An object driven by the feeding linear motors (53) can be formed small in size since the feed carriers (52) are installed on the bar (14), the feeding linear motors (53) having a small capacity can be adopted to simplify the structure of a transfer press (1).

Description

Technical field [0001] The invention relates to a workpiece conveying device of a pressure machine. Background technique [0002] Figure 27 A continuous automatic press 100 as a conventional press is shown. Four columnar support columns 121 are erected on a machine tool 123 located below the press frame 110, and a beam 120 is provided on the upper surface of the support column 121. A slider drive device is built in the cross beam 120 to drive the slider 122 located below the cross beam 120 up and down. In addition, an upper mold 112 is installed under the slider 122. A lower mold 113 is provided on the upper surface of the moving table 130 facing the slider 122, and the work is stamped and formed by the cooperation of the upper mold 112 and the lower mold 113. A pair of left and right transfer rods 114 and 114 are extended in parallel with the upper mold 112 and the lower mold 113 interposed therebetween. A pair of transfer rods 114, 114 are provided with fingers facing each ot...
