Abstract

PURPOSE:To enable only the required cargoes to be driven and save energy by means of such constitution that a transmission roller is brought into contact with a conveying roller through a turning frame by descending motion of a pallet of a roller which is movable downward and constantly protruded from the passing space under the lower side of the pallet. CONSTITUTION:Normally a detecting roller 9 is protruded through a movable frame 8 over the lower passages P-Q of a pallet by the weight of a motor 12, a transmission roller 11 is released from a conveying roller 4, and a brake 14 is brought into contact with the conveying roller 4. And when the pallet depresses the detecting roller 9, the brake 14 is released through the movable frame 8, and the transmission roller 11 is brought into contact with the conveying roller 4, which drives the conveying roller 4 and conveyes the pallet. Besides, the conveying roller 4 can be driven regardless of movement of the detecting roller 9 by connecting the movable frame 8 of the necessary drive unit D through a connecting rod 16 to a treadle gear. Thus, energy saving, free selectivity of length and width of the machine can be improved, and noise can be prevented, by distributing the driving power per each unit D of the conveyor.

こ狐。In view of the above points, this invention distributes the driving force to each unit of the drive source without driving the entire conveyor at once, thereby adjusting the drive position to suit factors such as the length and weight of the pallet. By setting a range and increasing or decreasing the number of units, and by driving what is necessary for the work, and by stopping the drive source when the pallet is stopped, efforts are being made to save power through operation. , Suko fox.

止するように構成してもよい。The relationship between the detection roller (9) and the transmission roller (11) is as shown in FIG. When held in the position shown in r, the detection roller (9) protrudes slightly beyond the passage surface 0-P of the lower surface of the pallet (1), and the transmission roller (11) separates from the circumferential surface of the conveyance roller (4). However, when the pallet (1) advances and pushes down the detection roller (9), the movable frame (8) rotates as shown in Fig. 6, thereby causing the transmission roller ( 9) is brought into pressure contact with the circumferential surface of the conveying roller (4), and the conveying roller (4) can be driven by the transmission roller (9). For this reason, a brake 7yu (14) is added to the movable frame (8), and when the transmission roller (11) comes into pressure contact with the conveyance roller (4) in connection with the rotation of the movable frame (8), the brake The transport roller (14) is the transport roller (4)
The housing transmission roller (11) is separated from the transport roller (4).
), the detection roller (9) becomes unloaded and the fourth
When restored to the position shown in the figure, Breaking Yu (14)
u Contact the circumferential surface of the transport roller (4) to stop the rotation of the transport roller (4) to ensure safety. A connecting hole (15) is provided in this movable frame (8), and a connecting rod (15) is provided in the connecting hole (L5) in the unit (D) located at the required position.
6) and attach it to the foot pedal device (17) as shown in Figure 2.
) etc., the conveyance roller (4) can be driven as necessary even if the end of the pallet (1) is not in contact with the detection roller (9). 12) In addition to the motor that rotates at a constant speed, a variable speed motor may be used if necessary.
Turn on the motor circuit using the rotational displacement of the movable frame (8),
When the detection roller (9) is pushed down, the motor (12) is started, and when the detection roller (9) is raised and returned to its position, the motor circuit is opened and the motor rotation is stopped. You may.

Claims

[Scope of Claims] 1. A movable frame is rotatably provided on one end of a mounting base that pivotally supports a conveyance roller in an idle state and that pivotally supports a detection roller so as to engage with the lower surface of the pallet and hang down. When the movable frame rotates due to the detection roller lowering, a motor-driven transmission roller attached to the movable frame is brought into pressure contact with the conveyance roller to drive the conveyance roller, and the pallet placed on the conveyance roller is moved. The pallet driving device is configured so that the transmission roller separates from the conveyance roller when the pallet passes the detection roller and the movable frame returns to the conveyor frame along the path of the conveyor. Intermittent drive conveyor drive device 02, which consists of an intermittent drive conveyor drive device appropriately disposed within the movable frame, is configured such that when the movable frame is returned to its position and the transmission roller is separated from the conveyance roller, a brake shoe attached to the movable frame brakes the conveyance roller. Intermittent drive conveyor drive device 0 according to claim 1
