雑な機構を要するので高価とカシ、また満足のゆく緩衝
効果が得られない欠点があった。In order to carry out the required work at the station in the assembly or processing section, the pallet on which the workpiece is placed is fixed at a predetermined position slightly floating above the chain by a locating pin that rises from below. The node is forcibly stopped and waiting by a pallet stop attached in front of the station. Furthermore, the following pallets collided with this waiting node and caused it to stop, making a loud impact sound. 75λ
In order to buffer the impact of a collision where the force is greater than or equal to the force, conventionally, for example, as in Utility Model Publication No. 56-47153, the rear crane rides on a pallet in front of the vehicle and uses a shock absorption mechanism using fluid pressure to absorb the impact. A similar mechanism was proposed, but this required a complicated mechanism, was expensive and expensive, and had the disadvantage that it did not provide a satisfactory cushioning effect.
更に従来では前方のパレットの再発進時にそれと後方の
パレットとの切離しが確実でないと云った新たな欠点が
生じている。Furthermore, a new drawback has arisen in the conventional method in that it is not possible to reliably separate the front pallet from the rear pallet when the front pallet is relaunched.

シ方向によシ摩擦係数の変るものを設けてもよい。The present invention eliminates this drawback. When the rear pallet collides with the stationary front pallet, the brake member of the rear pallet enters under the brake member of the front pallet, causing slippage between the two. Braking is performed not only by friction but also by sliding friction between the rear pallet and the fixed rail, and the impact is absorbed over a certain braking distance. This is so that the front pallet and the rear pallet can be easily separated when the front pallet is relaunched. In the illustrated embodiment, the roller is provided on the upper surface of the braking member, but it may be provided on the lower surface of the braking member instead, and in place of a roller with a one-way clutch, the upper surface of the braking member and the braking member may be provided on the lower surface of the braking member. One or both of the lower surfaces may be provided with a material whose friction coefficient changes in the sliding direction.

る。As shown in the second figure, the sliding contact surfaces 6 on both sides of the lower surface of the pallet main body 1
, 6 are in contact with the upper surfaces of the chains 5, 5, and due to the frictional force between them, the pallet main body 1 is sent forward with the workpiece placed thereon.
The braking member 11, which is pivotally supported on the front part by a shaft 13, advances with only its both sides 12 and the protrusions 14.degree. 14 on the lower surface of the brake member 11 in contact with the fixed rails 2, 2. At this time, since the braking member 11 is short, the protrusions 14 on both sides 12 and 12 of the braking member 11 are short.
, 14 will not come off even if it comes to the curved part of the fixed rails 2, 2. When the pallet main body 1 reaches the rear part of the stopped pallet main body 1 in front, the slope 5 of the brake body 21 first comes into contact with the roller and rides on it. At this time, since the rollers cannot rotate, a strong sliding friction force acts between them. Then, the roller slides on the lower surface of the brake body 21 and advances as shown in Fig. 3E, but at this time, the pallet 1 and
The weight of the brake member 11 acts downwardly on the roller as shown by arrow a in FIG. The front part of the pallet) lb is moved upward as shown by the arrow C, and the pallet) lb is slightly inclined upward, so that most of the sliding surfaces 6, 6 of the pallet body 1 are in contact with the chains 5, 5. Since the two are separated and only their rear ends are in contact, the frictional force between the two is reduced, and only the chains 5, 5 glide forward and move forward, and the rear pallet (lb) stops at that position. be done.

のである。In other words, the roller force of the braking member 11 of the rear barrel 1b enters under the braking body 21 of the front pallet 1a, thereby creating a frictional force due to the weight of the pallet body 1 and the total weight of the workpiece. occurs, and the protrusion 14,'
14 and the fixed rails 2, 2 due to the weight of the pallet body and the workpiece, the kinetic energy of the rear ball (lb) is partially consumed by its slight rise, and is completely consumed by the above frictional force. It is consumed and ceases to exist.

れるものである。As described above, the structure of the present invention is simple, and since the brake member of the following pallet is braked by entering under the front brake member, the rear pallet is placed between the brake member and the brake member. Braking is achieved by the frictional force, the frictional force between the braking member and the fixed rail, and the absorption of kinetic energy due to the partial rise of the rear pallet, so the impact is gradually absorbed over a certain braking distance, and the subsequent Valent stops smoothly and does not generate a lot of noise. In addition, when the stopped pallet in the front starts again, the brake member and the roller between the brake body rotate, so the brake body smoothly escapes from above the brake member due to rolling friction, and the pallet in the front moves away from the pallet in the rear. υ is easily separated.
