Embodiment 1

[0040] First, based on figure 1 The configuration of a gear production line for an automatic transmission to which the work stopper device A1 of the first embodiment is applied will be described.

[0041] In the gear manufacturing line of automatic transmission, such as figure 1 As shown, a gear member W (an example of a circular workpiece) immediately after being heated in a furnace for heat treatment is conveyed by falling down the chute of the workpiece conveyance path 1 based on the conveyor belt 11 and the slide plate 12 . The setting angle of the workpiece conveying path 1 formed by the conveying belt 11 and the straight path 12a of the slide plate 12 is formed at a steep angle of more than 55 degrees, for example, with little space. The slide plate 12 has a curved path 12b continuous with the straight path 12a, and the horizontal end position of the curved path 12b is set as a workpiece stop position.

[0042] The workpiece stopper A1 is arranged at the workpiece stop...

Embodiment 2

[0063] Embodiment 2 is a modified example in which the shapes of the pair of extensions 22 and 22 are different from those of Embodiment 1. As shown in FIG.

[0064] based on Figure 4 The structure of the pair of extension parts 22 and 22 in the work stopper A2 of Example 2 is demonstrated.

[0065] The pair of extensions 22 and 22 of the second embodiment extend in a substantially V-shape in the oblique direction from both sides of the base 21 fixed to the block 23 , and contact the gear member W to stop it. The inclination angles θ2 and θ2 of the pair of extensions 22 and 22 are formed to be angles that act 60 degrees from both sides of the line L in the direction perpendicular to the workpiece conveyance direction B to the travel direction B of the component. That is, the opening angle of the V shape of the blocker gear member W is set to about 60 degrees.

[0066] The pair of extension parts 22, 22 has first curved parts 22a', 22a' on the outer side of the part where th...

Abstract

The invention provides a workpiece stopping device capable of preventing the occurrence of scratches on a circular workpiece (gear member W). The workpiece stopping device (A1) comprises a workpiece conveying path (1) for conveying the gear member (W) after falling into a furnace via a sliding chute to be heated in the furnace, and a gear stopping part (W) for stopping the gear member at the stopping position of the workpiece conveying path (1). The gear stopping part is composed of a base part (21) and a pair of extension parts (22, 22). The base part (21) is arranged at the central portion of a workpiece stopping location in the workpiece conveying path (1) and is recessed towards the workpiece conveying direction (B). The pair of extension parts (22, 22) are extending in a generally v-shaped arrangement on the two sides of the base part (21) to abut against the gear member (W) so as to stop the gear member (W).

Description

technical field [0001] The present invention relates to a workpiece stopper for stopping a conveyed circular workpiece at a stop position on a workpiece conveyance path. Background technique [0002] Conventionally, there is known an impact absorbing device that includes a positioning stopper that determines a stop position of a workpiece to be conveyed, a shock receiving plate that is held movably with respect to the stopper, and absorbs the impact force of the workpiece. shock absorber (for example, refer to Patent Document 1). [0003] Patent Document 1: (Japan) Utility Application Publication No. 58-88004 [0004] However, in the conventional impact absorbing device, when the conveyed workpiece is a round workpiece such as a gear, a point collision occurs, the impact cannot be sufficiently absorbed, and scratches or the like may occur. Contents of the invention [0005] The present invention has been made in view of the above problems, and an object of the present in...
