Description

  The present invention relates to an oil recovery apparatus, and more particularly, to an oil recovery apparatus that can efficiently recover oil from small mechanical parts to which oil is adhered.

  Conventional methods for draining and oiling have been as follows. For example, for tempura draining of food fryer, de-oiling of machine cutting chips, draining after washing with vegetables, etc., a method of mainly feeding into a centrifugal separator to give high speed rotation has been adopted. There were also air separation systems using wind pressure and suction blowers.

  Conventional methods for draining and oiling have been as described above. In the system in which the centrifugal separator is charged to give high-speed rotation, there is a problem that the apparatus becomes large and the steps of loading and unloading the product are required.

  In addition, the air separation method using the wind pressure or the suction blower has a problem that the effect is weak in a state where the articles are stacked in multiple layers.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an oil recovery apparatus that can efficiently drain oil from small mechanical parts and the like.

  The oil recovery apparatus according to the present invention includes a component container that has a horizontal placement surface and that accommodates components having oil, and a slider crank mechanism that moves the component container in the vertical direction.

  Preferably, the slider crank mechanism moves the component container in the vertical direction so that the gravitational acceleration does not exceed 1.

  More preferably, the component container accommodates a steel ball for bearing.

  Two slider crank mechanisms may be provided for one component container.

  Since the component container that accommodates the component is moved up and down by the slider crank mechanism, the oil is drained from the component. Therefore, it is possible to provide an oil recovery device that can efficiently recover oil from small mechanical components with a simple configuration.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a main part of an oil recovery apparatus according to an embodiment of the present invention. 2 is an arrow view (plan view) of the portion indicated by arrow II-II in FIG. 1, and FIG. 3 is an arrow view of the portion indicated by arrow III-III in FIG. Here, the case where oil is recovered from a steel ball after the oil recovery device 10 quenches the steel ball for bearings will be described.

  1-3, the oil recovery apparatus 10 includes a slider crank mechanism 20, a container holding unit 30 connected to the slider crank mechanism 20, a component container 35 held in the container holding unit 30, and a component storage. And an oil recovery pan 36 for recovering oil from the steel balls. Note that the slider crank mechanism 20, the container holding unit 30, the component container 35, and the oil recovery pan 36 are held by the mount 40.

  The component container 35 includes six-stage cases 35a to 35f including steel balls for bearings after oil quenching. The six-stage cases 35a to 35f are integrated in the vertical direction. Each case 35a-35f is a rectangular parallelepiped shape having a bottom surface, and a plurality of steel balls are placed on the bottom surface. The container holding unit 30 moves up and down in the vertical direction along the linear guides 33a and 33b (see FIG. 3).

  The container holding unit 30 includes an elevating support unit 31 connected via a pin 31a to the other end of the link 25 connected to the rod member 28 of the slider crank mechanism 20, a roller conveyor 34 for carrying the component container 35, and the like. , Including a roller conveyor 34, and a housing frame 38 provided so as to surround the periphery of the component container 35. The housing frame 38 has twelve sides 39 constituting a rectangular parallelepiped, and has a work pressing member 37 that covers the component container 35 with its upper end. The storage frame 36 integrally connected to the elevating support portion 31 is moved up and down along the linear guides 33 a and 33 b by the slider crank mechanism 20.

  In addition, what was shown with the dashed-two dotted line in the figure shows the case where the container holding | maintenance part 30 was moved to the upper end and the lower end. Further, in FIG. 3, illustration of links and the like is omitted.

  The gantry 40 includes a motor 45 that drives the slider crank mechanism 20 and a motor support gantry 41e that supports a bearing support pedestal 27a that supports a bearing 27 that rotatably holds one end of a rod member 28 described later.

  Here, the six-stage cases 35a to 35f including the steel balls for bearing after oil quenching are moved up and down by the slider crank mechanism 20 via the container holding portion 35, whereby oil drops from the steel balls and drops. The recovered oil is recovered by the oil recovery pan 36.

  Next, the slider crank mechanism 20 will be described. FIG. 4 is a schematic diagram showing the overall configuration of the slider crank mechanism 20. Referring to FIG. 4, slider crank mechanism 20 includes a disk 21 that is rotated about a rotation axis 26 of a motor 45 (see FIG. 2). The disk 21 has pins 22 on its outer periphery.

  On the other hand, the rod member 28 can be moved up and down around a fulcrum 23 provided at one end thereof by a bearing 27. The rod member 28 has a long hole 24 on the other end side, and the pin 22 engages with the long hole 24. As a result, when the disk 21 is rotated about the shaft 26 in the direction indicated by A in the figure by the motor 45, the pin 22 slides along the long hole 24 accordingly, and the bar member 28 has the shaft 26 about the fulcrum 23. It moves up and down as indicated by C in the figure. At this time, the vertical movement of the link 25 is accelerated in the range indicated by the arrow B in the figure.

  Note that the position of the long hole 24 of the bar member 28 with which the pin 22 engages and the positional relationship with the pin 22 provided on the disk 21 depend on the rotation of the motor 45 and the vertical direction of the link 25 connected to the bar member 28. The movement is chosen to properly drain the oil.

  Here, oil is recovered under the following conditions.

  The diameter of the steel ball of the bearing is 0.8 mm to 4 mm, and this is accommodated in a case, and a plurality of cases are processed in a stacked manner.

  Each case has a rectangular parallelepiped shape of 772 mm length × 450 mm width × 300 mm height, and oil is recovered from a set of 6 stages. Here, the total weight is 160 kg including the case. The oil recovery time is 15 minutes per lot.

  The oil recovery target value shall be a minimum of half of about 2 kg of oil adhering in a 6-stage case.

  Next, the specification of the slider crank mechanism 20 will be described. 5A to 5C show the vertical position H (cm) (A) for each rotation angle of the pin 22 provided on the disk 21 constituting the slider crank mechanism 20 and the speed V (m / s). ) (B) and a graph showing the gravitational acceleration G (C), and Table 1 is data showing the contents thereof.

  Here, the slider crank mechanism 20 is driven under the following conditions.

  When the rod member 28 is in the horizontal position, the angle is set to 0 ° (see FIG. 4). In FIG. 5, 1 of the rotation angle corresponds to 0 °, and 37 corresponds to 360 °.

  The gravitational acceleration applied to the component container 35 by the vertical movement by the bar member 28 is prevented from exceeding 1. This is because if it exceeds 1, the steel balls for bearings housed therein will float up, and it will become impossible to drain the oil attached to the steel balls.

  As a result, in this embodiment, the rotational speed of the rotating disk pin is 50 rpm, the vertical swing dimension is 35.6 cm, the rotating disk is counterclockwise, and when the disk pin is rotated to about 110 degrees, the slider is Ascend to top dead center and move down.

  Referring to Table 1, the downward movement is from 120 to 250 degrees, and the maximum speed is 1.5 m / s, which is faster than the upward 0.65 m / s. Therefore, it is a downward swinging motion.

  At this time, since the gravitational acceleration does not exceed 1 G, the contained steel ball does not rise.

  Note that under such operating conditions, the vertical speed is changed by changing the number of revolutions of the inverter motor, and the optimum speed and pattern can be obtained for the diameter of the steel ball.

  Further, since oil is collected by the oil collecting pan 36, oil scattering can be prevented.

  Note that a shock absorber or a spring may be provided in the lower portion in order to ensure oil recovery when shaken off.

  As described above, in this embodiment, since the apparatus is configured to swing off using the difference in speed between the upper and lower sides using the slider crank mechanism, it is possible to effectively drain the oil.

  Next, another embodiment of the present invention will be described. FIG. 6 shows a front view corresponding to FIG. 1 in this embodiment. Referring to FIG. 6, in this embodiment, slider crank mechanisms 20 are provided at both ends in the longitudinal direction of component container 35.

  Since the other points are the same as in the previous embodiment, the same reference numerals are assigned to the portions corresponding to the previous embodiment, and the description thereof is omitted.

  In this embodiment, since the component container is held from both sides, the component can be moved up and down more stably than in the previous embodiment.

  Further, in this embodiment, since the oil can be drained while being put in the case, a plurality of articles contained in the case can be drained at a time.

  In the above embodiment, the case where six cases are collected and oil is collected in one process has been described. However, the present invention is not limited to this, and one case may be used, or an arbitrary plurality of cases may be used.

  Moreover, the apparatus is simple, and there are few components and maintenance is easy.

  In addition, in the said embodiment, although the case where the apparatus was used for oil collection | recovery was demonstrated, it is not restricted to this but can be used also for draining.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.

  According to the present invention, since the oil is drained by using the slider crank mechanism, the oil can be efficiently recovered from small mechanical parts, and therefore, it is advantageously used as an oil recovery device.
