JPH10291629A - Automatic lubricator for chain conveyer - Google Patents

Abstract

PROBLEM TO BE SOLVED: To keep distance between an automatic lubricator and a grease nipple constant, and allow lubrication even when a conveyer meanders, by providing an energizing means which transfers an automatic lubricator toward a ring plate of a chain conveyer and rollers which are attached to the automatic lubricator through a pair of ARMS. SOLUTION: An automatic lubricator 5 is energized so as to always move to a chain conveyer (conveyer) 1 side by a spring. On the side facing the conveyer 1, arms 17 which has a contacting roller 18 at its top and extends in the direction orthogonal to the conveyer 1 are mounted. Distance between a pair of arms 17 is equal to or a little larger than the interval between grease nipples 4 so that one of two contacting rollers 18 contacts with a ring plate 3 close to the automatic lubricator 5. Therefore, even if the conveyer 1 meanders and the grease nipples 4 displace back and forth, distance between the automatic lubricator 5 and the nipple 4 is kept constant, and lubrication is allowed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic refueling machine capable of refueling even if a chain conveyor meanders.

[0002]

2. Description of the Related Art An automatic chain conveyor lubricator is used to supply oil to rollers and link pins of a moving chain conveyor. This chain conveyor automatic refueling machine will be described with reference to FIGS. 1 is a chain conveyor, 2 is a roller, 3 is a link plate, and 4 is a grease nipple for supplying grease to rollers and link pins of the chain conveyor. Reference numeral 5 denotes a chain conveyor automatic lubricating machine (hereinafter, referred to as an automatic lubricating machine) having a lubricating arm 6 extending and contracting toward the link plate as well as a guide arm 7 extending and contracting toward the link plate 3.
The automatic refueling machine 5 is provided near the outside of the chain conveyor 1 and moves a fixed distance parallel to the traveling direction of the chain conveyor by a combination of a parallel link and a spring, a combination of a traveling rail and a spring, and the like. You can go back to

[0003] In Fig. 4, the chain conveyor 1 is moving rightward. The guide arm 7 moves forward and stops when the locking piece 7a at the tip of the guide arm 7 reaches the position where the grease nipple 4 passes. Chain conveyor progresses,
When the grease nipple 4 on the left side of the locking piece 7a comes into contact with the locking piece 7a, the center of the lubrication arm 6 coincides with the center of the grease nipple 4, as shown in FIG. The refueling arm 6 moves forward, and the refueling port 6a at the tip thereof fits into the base of the grease nipple 4 and stops. During this time, grease nipple 4
Pushes the locking piece 7a, the automatic lubricating machine 5 moves in the traveling direction of the chain conveyor, and grease is supplied. When a certain amount of grease is lubricated, as shown in FIG. 6, the guide arm 7 and the lubrication arm 6 are retracted, the locking piece 7a comes off the grease nipple 4, and the automatic lubricator 5 is returned to its original position by the spring force. Go to Meanwhile, the operations of FIGS. 4 to 6 are repeatedly performed, and all the grease nipples of the chain conveyor are refueled.

However, the rollers, link pins, rails, and the like of the chain conveyor 1 wear due to long-term operation.
The height of the grease nipple 4 is reduced or inclined, so that the oil supply port 6a of the automatic lubricating machine cannot be fitted to the base of the grease nipple 4, causing a problem that oil cannot be supplied. In order to solve such a problem, Japanese Utility Model Laid-Open No. 71112/1987 has been proposed.
This automatic refueling machine enables the refueling nozzle mounting base to move up and down,
In addition, the oil supply nozzle (corresponding to the oil supply port) can be tilted in accordance with the inclination of the grease nipple.

[0005]

However, when the rollers of the chain conveyor wear, a so-called meandering motion occurs in which the link plate moves while being displaced in the front-rear direction in FIG. When such a meandering motion occurs, the grease nipple is displaced in the front-rear direction. 62
The automatic refueling machine of No.-71112 does not have a function of changing the moving stroke of the refueling nozzle, so that the following problem occurs when the chain conveyor meanders.

(1) When the grease nipple is displaced forward due to meandering and the distance between the automatic lubricator and the grease nipple is shortened, the lubrication nozzle strongly hits the grease nipple,
The lubrication nozzle or grease nipple is damaged, making lubrication impossible.

(2) When the grease nipple is displaced rearward due to meandering and the distance between the automatic lubricator and the grease nipple becomes longer, the lubrication nozzle does not reach the grease nipple and lubrication becomes impossible.

[0008]

The present invention solves the above problems.
Urging means for moving the chain conveyor automatic lubricator main body toward the link plate of the chain conveyor; and a direction attached to the chain conveyor automatic lubricator at regular intervals in the length direction of the chain conveyor and orthogonal to the chain conveyor. A chain conveyor automatic refueling machine having a chain conveyor meandering follower comprising a pair of arms of a fixed length extending to the front end of the pair of arms and a contact roller attached to the tip of the pair of arms.

[Operation] Even if the chain conveyor meanders,
A biasing means for moving the chain conveyor automatic lubricator toward the link plate of the chain conveyor and a contact roller attached to the chain conveyor automatic lubricator via a pair of arms make the chain conveyor automatic lubricator and the grease nipple. The distance between them is kept constant. Thereby, even if the chain conveyor meanders, refueling becomes possible.
