Description

Description: INDUSTRIAL APPLICABILITY The present invention is used for a spacer intermittent supply device for arranging a plurality of spacers which support a long product from below at a predetermined interval when conveying a long product. The present invention relates to a spacer loader device.

When transporting a long product such as a shape member (hereinafter simply referred to as a product) in a lateral direction in a factory or the like, for example, if a wire or the like is directly wound around the product to support the product, there is a risk of damaging the product, Also, if only the both ends of the product are supported, the area around the middle part will bend significantly due to its own weight, and in some cases,
May cause harmful plastic deformation.

In order to effectively prevent such damage, flexure, and plastic deformation, the product may be supported via a prismatic spacer whose outside is covered with a suitable protective material such as felt. At this time, several spacers are arranged in parallel according to the length of the product, and the product is laid on the upper surface.When the product is transported, these spacers are collectively supported to support the product. It can be supported indirectly from below.

The spacers are arranged by an intermittent supply device for the spacers. The spacer intermittent device is a combination of a conveyor A that conveys the spacers S, S ..., a cassette box B disposed above the conveyor A, and a separation cylinder C (FIG. 5).

In the cassette box B, a large number of spacers S, S ... Can be stacked in multiple stages at right angles to the traveling direction of the conveyor A (direction of arrow A1 in the figure). An outlet B1 and an extrusion port B2 are formed.
The separation cylinder C is disposed further behind the extrusion port B2, and the separator C2 is attached to the tip of the rod C1.

Now, shorten the rod C1 so that the separator C2 has an extrusion port B2.
When the spacers S, S, ... Are lowered by one step when retracted to the rearward limit via (), the lowermost spacer S is positioned on the conveyor A. Then, when the rod C1 is extended, the separator C2 pushes the lowermost spacer S forward through the discharge port B1 by its front end, and receives the subsequent spacers S, S ... S can be separated from the subsequent spacers S, S ... And discharged downstream of the conveyor A. Therefore, in this device, by appropriately adjusting the discharge timing of the spacer S and the transport speed of the spacer S by the conveyor A, the required number of spacers S, S ... Can be placed.

According to such a conventional technique, since the lowermost spacer that bears the weight of a large number of subsequent spacers is forcibly discharged laterally by the separation cylinder, There is a problem that an unnecessary frictional force acts between the spacer and the spacer immediately after it, the postures of the two tend to be disturbed, and the spacer is easily clogged near the discharge port of the cassette box. In addition, since the spacers are stocked in multiple stages in the cassette box, if the spacers are clogged near the outlet, all the subsequent spacers in the cassette box must be removed in order to remove this spacer, There is also a problem that an excessive number of man-hours are required to restore the entire device and restore normal operation. Furthermore, the number of spacers in the cassette box is small,
The replenishment work must be performed frequently, and since they are piled up in a high line, the drawback that the replenishment work is difficult is inevitable.

Therefore, in view of the circumstances of the prior art, an object of the present invention is to provide a loader body that moves repetitively, an elevating frame that is mounted on the loader body, and a finger member with a locking pin that is mounted opposite to the elevating frame. By combining them, one unit of spacers that stand by at a predetermined standby position can be conveyed all at once, there is no problem of spacer clogging, and a series of inconveniences associated with restoration work and replenishment work can be eliminated. To provide a loader device.

Means for Solving the Problems The structure of the present invention for achieving the above object includes a loader main body that repeatedly moves between a predetermined standby position and a relay position, and an elevating frame mounted on the loader main body. , A pair of finger members mounted on the lifting frame so as to be adjustable in interval so as to be adjustable, and the finger members are
A plurality of retractable locking pins for urging in the advancing direction are provided on the respective facing surfaces, and at least two locking pins can be inserted into the recesses on the end surface of each spacer with respect to each finger member. The gist of the loader main body is that the finger member holds and conveys one unit of spacers aligned at the standby position and waiting by the locking pin all at once.

Action According to the configuration of the invention, the pair of finger members mounted to face the elevating frame face each other have lock pins that can be moved back and forth on their respective facing surfaces, and a pair of finger members can be connected via the lock pins. The spacer can be held all at once. In addition, the horizontal position of the lifting frame at this time can be moved between the standby position and the relay position by moving the loader body. That is, the spacers can be conveyed one unit at a time from the standby position to the relay position by aligning them in the standby position and waiting them.

Since the locking pin is movable back and forth and is biased in the advancing direction, for example, when holding a spacer having concave portions on both end surfaces, the locking pin corresponding to the concave portion enters the concave portion, Since the locking pin that contacts the end surface of the spacer is retracted, the finger member can reliably hold the spacer via the locking pin that has entered the recess. Also,
At this time, the relative positions of the respective locking pins and the spacers do not need to be regulated so strictly, and therefore, the position control of the elevating frame on which the finger members are mounted and the position of the loader main body are also
No sophisticated control mechanism is required and it may be a very general one.

At least two locking pins of each spacer can enter the concave portion of the end face, so that the spacers can be held non-rotatably through the plurality of locking pins, and there is no fear of the posture being disturbed during transportation.
