It relates to the supply device.

[Conventional technology]

Conventionally, when stacking articles in tiers, hard spacers made of wood, metal rods, plastic plates, etc. are arranged on the articles manually or mechanically, the articles are stacked on top of the articles, and then the hard spacers are arranged on the articles. It is common practice to do so.

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, for example, when plating or painting finished aluminum sash window frame shapes are loaded on a pallet or the like, a large amount is loaded all at once, but long spacers are required, and therefore hard spacers are required. When using
The weight is heavy, which makes it difficult to feed mechanically, requiring large-scale equipment, and requiring a large amount of manual labor. In addition, it takes considerable effort and time to collect the
There were problems such as the risk of damaging the finished product.

Means for Solving Problem C] The present invention was developed for the purpose of solving the above-mentioned problems and providing a supply device for supplying light and soft string-like spacers.Specific means include: A supply mechanism and a tension mechanism are arranged as a pair to face each other across a loading device,
This is configured integrally as a single or multiple juxtaposed shapes,

In FIG. 1, a guide rail 7 is installed horizontally on a base C with supports 6, 6, . . . long in the vertical direction in the figure. The guide rails 7 have two U-shaped cross-sections arranged in parallel with their openings facing each other, and shafts 7a and 7b are placed horizontally on both ends of the guide rails 7, and guide wheels 7c, 7d is attached.

A sliding body 8 is installed in the guide rail 7 by slidably and loosely fitting pulleys 8a, 8a into the opening. Said pulleys 8a, 8
A is attached.

A tension wire 8 is inserted between the guide wheels 7c and 7i from below.
b, and its both ends are attached to the sliding body 8 at the upper part.
One of the slide wheels 7d is connected to a motor 8c via a transmission device 8d, and the slide wheels 7d are rotated in the normal and reverse directions by the forward and reverse rotation driving of the motor 8c. The slider 8 is configured to be moved forward or backward by pulling the tension wire 8b that is wound around the slider 7d.

A tension body 9 of a spacer is attached to the upper part of the sliding body 8 along the length of the guide rail 7.

The tension body 9 has an outer body 9a formed into a tubular shape, and a sliding rod 9 in the inner hole.
A cylinder 9c is attached to the proximal end of the outer body 9a in such a manner that its rod tip is connected to the sliding rod 9b.

At the tip of the outer body 9a, upper and lower shaft support rods 9d and 9d' are projected in parallel from the front as shown in FIG. Put it on,
A chuck 10 is mounted via the shaft 9e.

As shown in FIG. 4, the chuck 10 is composed of a thousand-faced opening/closing bodies 9f, 9f' and actuating bodies 9g, 9g'. The shaft hole 9h is fitted onto the shaft 9e to form a substantially X-shape in plan view. Opposing teeth 9i, 9i are attached to the tip of each opening/closing body 9f, 9f', and each opening/closing body 9f, 9
Actuating bodies 9g, 9 are connected to the proximal end of 1' via shafts 9j, 9j'.
g′ is connected. A shaft hole 9k is formed at the base end of each of the winter operating bodies 9g and 9g', and a shaft 9 common to both shaft holes 9k is formed.

When the rod of the cylinder 9c is contracted, the tension body 9 having the above structure has a working body 9 as shown in FIGS. 3 and 4.
g, the opening/closing body 9f via 9g'.

Since the base end of 9M is pulled to the left in the figure, the opening/closing body 9f,
9f' is in a state where the engagement of the tip portion is open with the shaft 9e as the center. Therefore, when the cylinder 90 is extended, the operating body 9 is moved from the sliding rod 9b as shown in FIG.
In order to push the base ends of the opening/closing bodies 9f, 9f' to the right in the figure via the opening/closing bodies 9f, 9M, the teeth 9i at the tips of the opening/closing bodies 9f, 9M are pressed.
9i' closes and engages.

This device having the above configuration operates as follows.

In FIG. 1, after the profile E is placed on the elevated platform Da' by a forklift (not shown), the transmission tool 8d is driven by the normal rotation of the motor 8c of the tension mechanism B.
, the sliding body 8 advances to the right in the figure via the guide wheels 7c, 7d, and the wire 8b, and the tip of the tensioning body 9 passes over the profile E and moves the chuck 10 to the feeding mechanism A. It reaches the spacer S protruding from the tip of the chuck portion 5b.

Prior to this, the opening/closing bodies 9f, 9f' have their tips closed in the manner shown in FIG. 4, and the cutter rod 4b
, 4b', since the rod 41 of the cylinder 4g is in a contracted state, the cutter 4c is moved around the shaft 4a as shown in FIG.
, 4c' are disengaged to form a closed shape.

Therefore, the chuck 10 is stopped in the plane shown in FIG. 4 with the plane at a position 10' shown by the imaginary line in FIG. 2.

At the same time as this stop, the rod of the cylinder 9c at the proximal end of the tensioning body 9 is extended and the opening/closing body 9 is moved into the form shown in plan view in FIG.
f and 9f' are closed to engage the tooth bodies 91+91' and chuck the tip of the subesa S. When this chuck is completed, the motor 8C is reversed and the slider 8 is moved back to the left in FIG. moves forward to the position where it passes over profile E, and
A spacer S will be placed transversely on top.

At the next point in time, the cylinder 4j of the cutter mechanism 4 operates to extend the rod 41, and the connecting rod 4k that connects the rod 41 moves to the second
By descending in the figure, the arm 4j and the swinging body 4f connected thereto lower the left side in the figure about the shaft 4h. In conjunction with this swing, the left operating rod 4e descends to push down the cutter rod 4b, and the right operating rod 4e' rises to raise the cutter rod 4b', thereby causing the cutter 4
cr4c' forms a scissor blade-like sliding contact and cuts the spacer S at that position.

On the other hand, the cylinder 9C of the tension body 9 causes the rod to contract, causing the sliding rod 9b in FIG. 5 to retreat to the left in the figure. In order to pull it to the left in the figure, as shown in Fig. 4, the opening/closing body 9r,
9f' rotates around the shaft 9e to release the teeth 9i and 9i' from engagement.

After this process is completed, another group of 8 shapes are placed on the spacer S on top of the shape E using a forklift, etc., and the mounting table Db' of the lifting/lowering loading machine is adjusted to the height of the spacer and the height of the shape E. The same spacer supply process as described above is repeated by lowering the spacer. These series of driving operations are automatically controlled by a control mechanism that utilizes sensors (not shown) provided at appropriate locations and a general microcomputer.

Note that the present invention is not limited to the above configuration. For example, the spacer delivery and supply adjustment mechanism 3 is attached to the upper part of the support column 2, but depending on the location, the cutter mechanism 4 may be disposed on the upper part of the support column 2, and the delivery adjustment mechanism is attached to the lower part of the support column. They may be hung or placed side by side.

Since the cutter mechanism 4 only needs to be able to cut the spacer S, its configuration may be changed in any way.

The tension mechanism B may also use a cylinder as the sliding mechanism for the sliding body. Furthermore, the chuck 10 can also be of an electromagnetic opening/closing type.

〔effect〕

Since the present invention is configured as described above, it has many excellent effects as described below.

(a) Since a string-shaped (paper string) spacer is used instead of a square or plate-shaped spacer, the supply device can be made smaller and simpler like this device, and the spacer is not bulky and weighs less. Since it is also light, it is possible to increase the amount of cargo that can be loaded onto pallets, etc.

(+) Since a thin paper string can be used as the spacer, it does not take up much storage space and can be easily collected after use.

(c) Since a string-like spacer is used, it can be supplied continuously, and since the spacer is stretched between the supply mechanism and the tension mechanism, it requires less energy than when supplying spacers such as square timbers or plate materials. It can be supplied without damaging the product.
