Description

[Detailed Description of the Invention] This invention relates to an alignment machine that sorts and takes out veneer plates other than rectangular shapes obtained by punching, etc., such as shutter pieces, in each posture.

Conventionally, this type of veneer is punched and dropped into a box from a chute, resulting in the veneer being in a variable position within the box.

When setting these in a layered manner in the hopper of an automatic machine, it must be manually set in one position, which is very time consuming and has the disadvantage of being inefficient and tiring. .

In view of the above points, this arrangement machine takes out the veneers with different orientations stacked in a magazine, sorts them according to orientation, and automatically aligns them to eliminate the above drawbacks. Our goal is to provide the following.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

In the figure, reference numeral 1 denotes a horizontal sliding plate that moves forward and backward intermittently, and in the case shown, the sliding plate 1 moves forward and backward by connecting a cylinder 2 to the sliding plate 1.
This is done by the expansion and contraction operations of the cylinder 2.

Further, a magazine 3 is provided directly above the slide plate 1, the lower end opening of which is closed by the upper surface of the slide plate 1 and supported in a fixed position.

This magazine 3 has a veneer a with various postures.
are stored in a stacked state.

Furthermore, a recess 4 is provided on the upper surface of the slide plate 1, into which the lowest single plate a in the magazine 3 is fitted when the slide plate 1 stops moving backward.

As mentioned above, when the slide plate 1 stops moving forward, a sliding body 5 is provided which can move forward and retreat from directly above the recess 4, and this sliding body 5 has an elevating and lowering mechanism that can be lowered to match the recess 4. A body 6 is provided.

In the illustrated case, the sliding body 5 moves forward and backward, and the elevating body 6 moves up and down by extending and contracting the cylinders 7 and 8.

Further, on the lower surface of the elevating body 6, a single plate a in the recess 4 is provided.
A holding device 9 is provided which supports the slider 5 and continues to support it for a certain period of time after the sliding member 5 stops moving forward.

In the illustrated case, the above-described holding device 9 supports the veneer a by suction, but an electromagnet that is energized for a set time by energization may also be used.

Furthermore, at least one of the bottom surface of the recess 4 and the lower surface of the elevating body 6 is provided with a detection device A that detects the four postures of the veneer a.

In the illustrated case, the above-mentioned detection device A has four through holes that coincide with the recess 4 and the elevating body 6, and two or three of which are closed by the veneer a depending on the attitude of the veneer a. stomach. B. C. D, i'. B'. C'. Provide a through hole A'. B'. C'. The air supplied from D' passes through the through hole A, which is closed by the veneer a. B. C.
It is designed to detect pressure fluctuations, but it may also be detected electrically (with a phototube) or mechanically (with a protruding detection rod).

Immediately below the elevating body 6 when the sliding body 5 stops moving forward, there are four laminated tables 10 having pins c that change positions for each posture of the single plate a and that match the two through holes b of the veneer a. 11, 12, and 13 are interchanged.

In order to replace the laminated tables 10, 11, 12, and 13, as shown in the figure, a slider 14 is provided that intersects at right angles to the advancing and retreating direction of the sliding body 5, and each recessed portion 15 is placed in a quarter position on the upper surface of the slider 14. The lower ends of the stacking tables 10, 11, 12, 13 are fitted and supported by a retaining plate 16 which is screwed, and a forward/reverse motor 18 is connected to the female thread 17 of the slider 14.
The stacking tables 10, 11, 12, and 13 can be replaced by screwing in the male screw 19 and rotating the motor 18 in the forward and reverse directions, but a rotary table may also be used.

In the illustrated case, a pair of left and right magazines 3 are arranged side by side on a sliding plate 21 that is slid by a cylinder 20, so that the magazines 3 can be replaced.

In the figure, reference numeral 22 denotes a detection device (in the illustrated case, a phototube is used) that detects the fixed amount when the stacked amount of the veneer a inserted through the pin c reaches a fixed amount. 2
3 is a guide shaft of the slider 14; 24 is a seat plate guided by a guide portion 25; the cylinder 7 is connected to this seat plate 24, and the sliding body 5 is attached to a pillar 26 on the seat plate 24.

The alignment machine according to this invention has the above-mentioned configuration. Next, the alignment method will be explained. First, the magazine 3
The veneers a are stored so that they are in a stacked state.

At this time, the posture of the veneer a varies.

When the slide plate 1 is moved backward by the contraction operation of the cylinder 2, the lower end opening of the magazine 3 and the recess 4 coincide with each other when the slide plate 1 stops moving back, so that the lowest veneer a falls into the recess 4. .

Thus, the slide plate 1 advances and retreats due to the extension of the cylinder 2.
When the sliding body 5 stops with the recess 4 directly below it, the cylinder 8 extends and the lifting body 6 descends. The holding device 9 then operates to hold the veneer a on the underside of the lifting body 6.

Also, at this time, the detection device A operates to open the through hole. B'. C'. Through hole A from D'. B. C. A through hole is closed by a veneer a, for example, in the case of FIG. B. C is the through hole D in the case of FIG. 6, and through hole I is in the case of FIG. In the case of Fig. 8, b. Ha is closed,
Four different postures are detected based on the pressure fluctuations caused by the different closures, so each stacking table 11, 12, 1
A stacking table having a pin c at a position that matches the through hole b of the veneer a held by the elevating body 6 of 3 and 10 is operated by the motor 18 to drive the male screw 19 and slide the slider 14. , the above-mentioned elevating body 6
Stop in front of.

After that, the elevating body 6 is raised by the contraction of the cylinder 8, and the sliding body 5 is advanced by the extension operation of the cylinder 7, so that when the sliding body 5 stops, the pin c and the through hole b of the veneer a coincide. .

When the sliding body 6 is lowered by the extension operation of the cylinder 8, the upper end of the pin c fits into the through hole b, and then the holding of the veneer a by the holding device 9 is released. penetrates.

Thereafter, the cylinder 8 is contracted to raise the elevating body 6, and the cylinders 7 and 2 are contracted to move the sliding body 5 and slide plate 1 backward.

By repeating the above steps, each stacking table 10, 11, 1
The pins c of 2 and 13 are passed through the through holes b, and the veneers a in each posture are sorted and aligned.

Note that although the veneer a was laminated by passing the pin c through the through hole b, the veneer a may be laminated using an appropriate guide instead of the pin c.

As described above, according to the alignment machine of this invention, the reciprocating slider has a recessed portion on the upper surface of the tip into which the veneer fits, and the retracting slider accommodates the stacked veneers with different postures, and stops the slider from retracting. a magazine provided so that the lowest single plate fits into the above-mentioned recess that coincides with the lower end opening; a sliding body provided so that it can move forward and backward so that it faces directly above the recess when the slider stops moving forward and stops moving backward; An elevating body provided on the sliding body so that it can be raised and lowered, a holding device provided to hold the veneer on the lower surface of the elevating body, and a posture of the veneer detected on at least one of the lower surface of the elevating body and the bottom surface of the recess. A detection device is installed so that the sliding body moves forward, and when the sliding body stops moving forward, the position of the single body directly under the elevating body changes depending on the result of the detection device.
In addition, since it is constructed with a stacking table provided so as to stack veneers in each posture, veneers in various postures in the magazine can be automatically sorted and stacked in each posture.

Therefore, unlike conventional manual alignment, efficient alignment can be achieved.
