ある。 Conventionally, as shown in FIGS. 4 and 5, in pallets that reciprocate along guide rails 7 and 8 provided on both the left and right sides of a pallet 6', a pallet conveyor is used as a means of conveying the pallet. The driven side rack 4', which is attached by a bolt 12' along the center line in the traveling direction, is engaged with the driving side pinion 11' installed at an arbitrary location. On the other hand, on both left and right sides of the lower surface of the pallet 6', there are guide members 2' that slide into guide rails 7 and 8.
5', and the guide members 2', 5' and the driven rack 4' were manufactured separately.
The guide members 2', 5' and the driven rack 4', which require higher precision than the pallet body 1', are separately attached to the pallet body 1'. The driven rack 4' was provided along the center line M-M in the traveling direction on the lower surface of the pallet main body 1' in order to allow the pallet 6' to move smoothly with respect to the guide rails 7 and 8 without tilting. was considered necessary. However, the inventor of the present invention had doubts about this point and attempted to move the driven rack from the center line M-M, and as a result, the present invention was completed.

この考案は被動用ラツクをガイド部材と一体化
することにより、パレツトの移動時に傾きが生じ

組立作業の簡単化を図つたものである。 In this invention, by integrating the driven rack with the guide member, the pallet can be moved smoothly without tilting, and the pallet assembly work can be simplified.

図面に基いてこの考案に係るパレツト搬送用被
動部材の一実施例を説明する。 An embodiment of a pallet conveying driven member according to the present invention will now be described with reference to the drawings.

れている。 1 is a pallet body, 2 is a linear guide member fixed to either the left or right side of the pallet body 1 with a bolt 3, and the inner vertical wall of the guide member 2 has linear teeth with racks or pins arranged at regular intervals. A mold driven member 4 is provided. 5 is a linear guide member provided on either the left or right side of the pallet body 1;
The inner vertical wall of this guide member 5 is not provided with any driven member. The pallet 6 is constructed as described above.

嵌合している。 7 and 8 are left and right guide rails placed between the setup station 9 and the processing station 10;
The right-angled downward corners of the guide members 2 and 5 of the pallet 6 are fitted into the L-shaped grooves of the guide rails 7 and 8, respectively.

動する。 Reference numeral 11 denotes a drive side pinion installed at an arbitrary location, and meshes with the driven member 4. Therefore, when the driving pinion 11 is rotated, the pallet 6 moves along the guide rails 7 and 8 via the driven member 4.

る。 That is, the pallet transport mechanism according to this invention is composed of a setup station 9 and a processing station 10.
The L of the guide rails 7 and 8 arranged on the left and right between
In the pallet 6 which reciprocates along the mold groove,
The left and right linear guide members 2, 5 are attached to the lower surface of the pallet body 1 on both sides with bolts 3. A linear toothed driven member 4 is attached to the inner vertical wall of one of the linear guide members 2, 5.
The driven member 4 is provided and integrated with a guide member 5 to form a pallet 6, and the right-angled downward corners of both guide members are fitted into the L-shaped groove of the guide rail, and the driven member 4 is engaged with a driving side pinion 11 installed at an arbitrary position.
With this construction, when the guide member 2 is attached to the pallet body 1, the driven member 4 can also be attached at the same time, so that assembly work which requires precision is simplified.

ドレール７によつて受けられるためだと考えられ
る。 At first glance, it appears that if the driven member 4, which is provided only on the inner vertical wall of one guide member 2, is pushed or pulled, the pallet 6 will tilt with respect to the guide rails 7 and 8, making smooth movement impossible. However, when we conducted an experiment, we found that there was almost no difference in movement resistance. This is thought to be because a force is applied to the driving pinion 11 in a direction that presses the driven member 4 against the guide member 2, and this force is received by the guide rail 7.

それ故、この考案によれば、部品点数の減少、
パレツトの軽量化、コスト低減を図ることが出来
るものである。 Therefore, according to this invention, the number of parts can be reduced,
This makes it possible to reduce the weight and cost of pallets.

しく容易である。 Furthermore, in the above embodiment, the guide member 2 and the driven member 4 are integrally molded, but the guide member 2 and the driven member 4 are manufactured separately, and the driven member 4 is attached to the guide member 2. There is no problem even if the guide member 2 is attached to the pallet body 1 after being integrated. In this way, machining is easy. Furthermore, compared to the work of directly attaching the driven member 4 to the pallet body 1, the work of attaching the driven member 4 to the guide member 2 before assembly is significantly easier.
