Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a conversion transfer device for converting a plate material by 90 degrees and transferring it.

[0002]

2. Description of the Related Art For example, in the woodworking field, a work material is continuously flowed in a straight conveying line, and cutting, bonding, and the like are performed on both front and rear sides and left and right sides of the work material. In order to do that, 90
It is essential to turn once. FIG. 5 shows an example of a conventional conversion device. As a main configuration, a turntable 11 is arranged in a transfer line 10, and a clamp means 12 and a lifting means 13 are provided on the turntable 11.

That is, conventionally, when the work material 14 is transferred onto the turntable 11, the clamping means 12 is operated to hold it, and is lifted onto the line 10 by the lifting means 13, and in this state, the turntable 1 is held.
1 is turned and the processed material 14 is changed by 90 degrees. Then, after the conversion, the turntable 11 is lowered and the clamp means 12 is opened, whereby the processed material 1
4 is returned to the line 10.

[0004]

As described above, in the related art, since it is necessary to lift or lower the work material 14 on the transfer line 10, redundant operation time is inevitable and work efficiency is reduced. There was a problem.
Moreover, it was pointed out that not only that, but also the structure becomes complicated and a conversion failure occurs due to a shift in operation timing.

The present invention has been made in order to solve the above-mentioned conventional problems, and has been made to solve the problems. For example, a plate material capable of performing a conversion operation quickly and surely and reducing the cost in terms of the structure, etc. To provide a conversion transfer device.

[0006]

In order to achieve the above object, the conversion transfer device according to the present invention is as follows. That is, the gist of the present invention is
A conveyor for transferring the plate material from the upstream side to the downstream side is provided, and a conveying means having a low-speed moving portion and a high-speed moving portion is arranged on the conveyor surface of the conveyor, and the low-speed moving portion and the high-speed moving portion are respectively provided with the plate material The point is that the materials are sent to both of them at the same time.

A second aspect of the present invention is that the feeding means in the first aspect is constituted by one conical roller.

A third aspect of the present invention is to dispose a plate member pressing means composed of a plurality of idle rollers on the upper side of the feeding means in the first aspect.

Further, as a fourth aspect, the gist of the invention is to dispose an abutting member that comes into contact with the end of the plate material on the downstream side of the low-speed traveling section in the traveling means of the first aspect.

[0010]

The plate material on the feeding means has its transfer posture changed depending on the difference in the amount of transfer between the low-speed moving portion and the high-speed moving portion, and is converted on the conveying surface with the low-speed moving portion as the starting point. When the plate turns 90 degrees, it is transferred to the downstream conveyor and transferred.

In the conical roller, the small diameter portion can be the low speed feeding portion and the large diameter portion can be the high speed feeding portion in the longitudinal direction. This conical roller can perform required traveling rotation with a single drive source.

By pressing the plate material by the pressing means, it is possible to reliably transfer the transfer force of the feeding means and eliminate the deviation of the plate material during conversion. Since each idler roller rotates in synchronization with the conversion speed, the conversion operation can be performed smoothly.

By abutting the abutting member on one end of the plate member, the starting point of the conversion operation can be set reliably. This contact member releases the contact state with the change in the posture of the plate material, and therefore does not hinder the transfer to the downstream side.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the conversion and transfer device according to the present invention will be described below. FIG. 1 is a plan view and FIG. 2 is a side view. Reference numeral 1 is a roller type first conveyor arranged on the upstream side (upper part of FIG. 1). One side (right part of FIG. 1) is arranged with a slight inclination so as to be transferred along the ruler plate 1a. The conveyor 1 is positively rotated by a drive motor (not shown).

Reference numeral 2 denotes a roller type second conveyor which is connected to the first conveyor 1 and is arranged on the downstream side (downward in FIG. 1). This second conveyor 2 is driven by a drive motor (not shown). Actively rotates at the same speed as the conveyor 1. The heights of the transfer surfaces of the first and second conveyors 1 and 2 are set to match each other. The ruler plate 1a is extended to the second conveyor 2 and arranged.

A is a first conveyor 1 and a second conveyor 2
Conveying means consisting of a conical roller (a truncated cone roller) 3 arranged near the connecting part with the conical roller 3 is such that the narrow diameter side approaches the ruler plates 1a and 2a, and the large diameter side moves Place it towards the other side. Reference numeral 4 denotes a drive motor for rotating the conical roller 3. The small diameter portion is the low speed feeding portion a and the large diameter portion is the high speed feeding portion b.

In the above, the speed of the high-speed feeding section b is the first
And the transfer speed of the second conveyors 1 and 2 is almost the same. Further, the conical roller 3 is arranged with the transfer surface set slightly higher than the transfer surfaces of the conveyors 1 and 2. A contact member 5 is provided immediately downstream of the low-speed transport section a so as to project on the conveying surface. This contact member 5 contacts one side of the front end of the plate material P transferred from the upstream side.

B is a pressing means for the plate material P disposed above the feeding means A. The pressing means B is composed of a large number (five in the embodiment) of idle rollers 6 arranged in the width direction (left and right direction in FIG. 1).
Compose by. The pressing means B is supported so that the height can be adjusted by the elevating means 7, and corresponds to the thickness of the plate material P. The pressing means B may be an idling or driving roller having the same shape as the conical roller 3 described above.

Reference numeral 8 is a guide roller arranged in an arc shape with the vicinity of the mounting position of the abutting member 5 as a center. The guide roller 8 is composed of a free-wheeling roller, and its guide surfaces are the first and the first. Set slightly higher than the two conveyors 1 and 2.

The constitution of the conversion transfer device according to one embodiment is as described above, and operates as follows. That is, the plate material P supplied onto the upstream first conveyor 1 is regulated on one side by the ruler plate 1a by the width-shifting action of the conveyor.
Transferred straight to the downstream side. When the front end of the plate material P reaches the feeding means A by the above-mentioned transfer, the plate material P is converted and moved due to the speed difference of the transfer surface.

Since this conversion operation is performed while the front end one side is in contact with the contact member 5 and is supported by the arc-shaped guide roller 8, there is no positional deviation and it is smooth. (See FIG. 3) When the posture of the plate P changes significantly, one side of the plate P separates from the ruler plate 1a, and the contact member 5 releases the contact. Then, at the time when the conversion of 90 degrees is completed, the plate material P is transferred onto the second conveyor 2 on the downstream side, and is transferred rearward by this conveyor 2. (See Figure 4)

While the plate material P is transferred in contact with the feeding means A, the idle roller 6 acts on the upper surface of the plate material P to prevent the slippage from being displaced. Since each of the idler rollers 6 rotates according to the conversion speed, the conversion operation is smooth. The idler roller 6 and the conical roller 3 of the feeding means A are preferably made of a rubber material.

By the way, in the above-mentioned embodiment, the feeding means A is constituted by one conical roller 3.
However, it is also possible to replace the configuration in which the plate member P is contacted with a roller group having the same diameter and these roller groups are driven separately with a rotational speed difference. Further, the feeding means A and the pressing means B adopt the line contact roller system, but instead of this, a surface contact belt system may be adopted.

[0024]

As is apparent from the above description, according to the conversion transfer device of the present invention, the plate material can be transferred without stopping 90
It is possible to change the degree. Therefore, it has an excellent effect that a great improvement in working efficiency can be achieved as compared with the conventional case. In addition, since the structure can be simplified, the cost can be reduced, and the conversion operation can be surely performed without the problem of the operation timing.
