Problems solved by technology
[0005] However, in the above-mentioned pallet conveying device, since a plurality of pallets are sandwiched between the left pallet conveying mechanism and the right pallet conveying mechanism for conveying, if the conveying distance is relatively long, the pallets held between them may be lost. The problem of increasing numbers of
In addition, in the above-mentioned pallet conveying device, since a plurality of pallets are conveyed by a quadrangular rail, there is a problem that when conveying a plurality of pallets between the left pallet conveying mechanism and the right pallet conveying mechanism, if not After either one of the left and right pallet conveying mechanisms advances the pallets and the other of them reverses the pallets, they cannot be used to hold multiple pallets again for conveying
Therefore, there are the following problems to be solved: In the case of a long conveying distance, the above-mentioned process needs to be repeated many times, so it is difficult to convey the pallet quickly within a long distance

Embodiment Construction
[0019] Hereinafter, the best mode for carrying out the present invention will be described based on the drawings.
[0020] figure 1 The tray conveyance apparatus 10 of this invention is shown. In each figure, three axes X, Y, and Z that are perpendicular to each other are set. The X axis is defined as an axis extending approximately horizontally and laterally, the Y axis is defined as an axis extending approximately horizontally in the front-back direction, and the Z axis is defined as an axis extending approximately horizontally. The configuration of the tray conveyance device 10 will be described as an axis extending in the vertical direction. The pallet conveying device 10 of the present embodiment is an example of a pallet conveying device installed on a production line for manufacturing stators of electric motors such as electric motors, in which three processing stations 11 to 13 are arranged in a row at predetermined intervals in the X-axis direction. Case. Each of t...

The invention discloses a tray conveying device and a tray conveying method, wherein the device is capable of rapidly and stably conveying a tray for a long distance without increasing the number of trays. The tray conveying device comprises a tray guide rail (16) used for loading the tray (21) capable of moving in the length direction; first and second pulleys (23, 24) which are separately mounted in the length direction of the tray guide rail (16); a circulating belt (27) mounted on the first and second pulleys (23, 24) and used for engaging the trays (21) loaded on the tray guide rail (16); a first actuator (28) capable of rotationally driving the first pulley (23); a second actuator (29) configured to be capable of being synchronously controlled with the first actuator (28) so as to rotationally drive the second pulley (24). The tray conveying method is capable of rotating the first pulley (23) and the second pulley (24) through synchronization control so as to circulate the circulating belt (27) for conveying the tray (21).
Description
technical field [0001] The invention relates to a pallet conveying device and a pallet conveying method for locking a plurality of pallets carrying workpieces on an endless belt for conveying. Background technique [0002] Conventionally, a belt conveyor is known in a production line in which workpieces are conveyed by a conveyor belt and predetermined processing is performed on the workpieces by a machine tool at a processing station at a conveyance destination. However, in such a conventional belt conveyor, for example, when carrying a heavy workpiece such as a stator, the inertial force acting on the workpiece is large when the workpiece is stopped, so it is difficult to increase the conveying speed, and it is difficult to rely on Problems with accurate positioning of the stoppers. [0003] In order to solve such a problem, the present applicant has proposed a pallet conveying device that conveys a plurality of pallets carrying workpieces to a processing station on a qua...
