Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor device in which conveying jigs are installed at predetermined intervals on an endless chain, and more specifically, in the above-mentioned conveyor,
This makes it possible to shorten the interval between conveying jigs in a determined required section.

In general, conveyor devices in which conveying jigs are installed at predetermined intervals on an endless chain are widely known.
For example, a typical conveyor is a peg conveyor device as shown in FIG.

In the peg conveyor device shown in Figure 1,
A peg attached to an endless chain 3 stretched between two sprockets 6 and 7 by an attachment (not shown) is used to transport the plate-like object 1 transferred by the preceding conveyance device 2. stick 4
(transport jig), and then the plate-shaped object 1
is conveyed in an inverted state by being supported by peg rods, and delivered to the conveyor 5 at the subsequent stage.

The peg conveyor device shown in FIG. 1 has extremely excellent effects in terms of conveying plate-like objects.

That is, the plate-shaped object such as plate glass that has been transported by the conveyor 2 in the previous stage is then transported by the peg conveyor in an inverted state as shown in the figure, so that the transport path is essentially such that the object to be sent lying down is upright. Since the conveyance is extended, sufficient cooling, drying, etc. can be performed on the peg conveyor as necessary, and the peg conveyor itself also functions as a storage device. In the above-mentioned peg conveyor, the minimum peg interval is determined by the substantial thickness of the plate-shaped object to be conveyed.
Essentially, it is determined in consideration of the work of discharging from the peg conveyor.

That is, this is to prevent damage caused by collision between the plate and the next peg when the plate is taken out by the peg conveyor.

When taking out plate-like objects from the peg conveyor manually, it is necessary to ensure sufficient spacing between the pegs to prevent the above-mentioned damage. Even when the peg conveyor is used, due to the structure of the peg conveyor, the plate is turned over at any time, so this needs to be corrected, and as in the case of manual operation, the interval between the pegs is determined by the thickness of the plate. This required a much larger spacing than the minimum spacing determined.

However, increasing the peg spacing substantially lengthens the conveying path and also reduces the original advantage of the peg conveyor, which is that it does not function as a storage device.

According to the present invention, wide peg spacing is particularly required at the take-out section, and in the transportation meridian before that, the original advantages can be fully obtained by making the peg spacing as small as possible. It was completed based on knowledge.

Hereinafter, the present invention will be explained based on the drawings.

FIG. 2 is a diagrammatic explanatory diagram showing one embodiment of the present invention, and FIG. 3 is a plan view mainly showing a chained state.

Reference numerals 3 and 3' designate endless chains, and the endless chains 3 and 3' are stretched over sprockets 6, 6', 7, and 7' provided on shafts 10 and 11, respectively. The length of the endless chains 3, 3' is longer than the actual length between the sprockets 6, 6', 7, 7', and the endless chains 3, 3' are longer than the actual length. is folded at the upper part between the peg bars 4a (conveyance jig) and the peg bars 4b of the peg conveyor, so that the distance between the peg bars 4, 4 in that part is shortened compared to other parts. I have to.

The endless chains 3, 3' are connected to the peg rod 4.
b ~ Sprocket 6, 6' ~ Sprocket 7,
7' to the path of the peg rod 4a, and is provided so that no tension is applied between the peg rods 4a and 4b.

In addition, the peg rod 4 is attached to a peg rod mounting tool 12 (fourth,
5 and 6), and a rubber film 13 or the like may be provided on its surface to protect the transported object 1. Also, a pair of pushing tools 14, 1 are provided which reciprocate back and forth by the distance between the peg bars in order to fold the endless chains 3, 3' at the upper part and feed them intermittently.
4 (see FIGS. 2, 7, and 8, and will be explained in detail later), and the pushing tool 14 is provided with a side plate 15.
One double rod cylinder 1 installed in
6 through chains 17, 18, 18'. In addition, 19 and 20 are sprockets for tensioning the chain 17, and 21 and 2 are sprockets.
1', 22, 22' are chains 18, 1, respectively.
These sprockets 20, 21, 22 are fixed to a shaft 23.

Furthermore, wheels 2 are provided at both ends of the peg rod mounting tool 12.
4 is rotatably mounted, and the wheels 24 are
Guide rail 2 fixed to side plates 15, 15'
5 is inserted into the groove 26 of the guide rail 2.
5 allows the endless chains 3, 3' to move forward smoothly. A push-down attachment 27 is attached to the folded portion of the endless chain 3, 3' located below the endless chain. When the pushing tool 14 is activated by engaging the lower part of the pushing member 29 provided on the member 28,
The endless chains 3, 3' are prevented from being bent upward. (See Figure 6) Next, Figure 7 shows the mounting structure of the pushing tool 14.
This will be explained in detail with reference to FIG.

The pushing tool 14 is rotatably inserted into a shaft 31 fixed to the sliding plate 30, and has a semicircular notch at its tip so as to engage with a pin 32 connecting the links of the endless chain 3. The rear end is heavier than the tip, and the pushing tool 14 is
It is always inclined in the direction shown in FIG. The degree of inclination is determined by the sliding plate 3.
This adjustment is made by changing the length of a screw 34 screwed onto a pushing tool 14 that contacts a pedestal 33 provided at 0. Further, the sliding plate 30 has a bearing 35 attached to the bolt 36.
and its bearing 35
is inserted into a guide bar 38 having a groove 37 provided in the side plate 15', and allows the sliding plate 30 to slide back and forth along the groove 37 of the guide bar 38. A fitting 39 is provided at the lower end of the sliding plate 30.
9 is fixed to the engagement tool 40 of the chain 18,
The sliding plate 30 is slid back and forth by the operation of the one rod cylinder 16, and the pushing tool 1
4 is reciprocated back and forth. A similar pushing mechanism configuration is also attached to the chain 18' side.

In addition, on the side plate 15 of the peg rod 4a portion where the interval between the peg rods 4 is shortened, there is a reversal prevention plate 4 attached to the side plate 15 with the pin 41 as the center of rotation.
It is preferable that the endless chains 3, 3' be prevented from reversing by always being pressed against the peg rod mounting device 12 by the spring 43. (Fig. 9) In order to help the sprockets 6, 6', 7, and 7' rotate smoothly, sprockets 44 and 45 are provided at the ends of the shafts 10 and 11, respectively, and a chain is connected between the sprockets 44 and 45. 46 is preferably stretched. (FIG. 3) Next, to explain the operation of the present invention, the pushing tool 14 is moved backward from the position of the pushing tool 14 in FIG. 2 by the operation of both rod cylinders 16,
The peg rod mounting tool 12 of the next peg rod 4c is engaged with the link pin 32 of the attached endless chain 3, 3'. Next, both rod cylinders 16 operate in opposite directions to move the pushing tool 14 back in the forward direction and move the peg rod 4c to the position of the peg rod 4a. Then, the endless chains 3, 3' are folded downward, changing from the state shown in FIG. 4 to the state shown in FIG. Peg stick 4a
The distance between the peg rod 4c and the peg rod 4c is shortened.

Further, when the pushing tool 14 moves back and rotates the endless chains 3, 3' intermittently, the rotation is transmitted to the peg rod 4b, which moves forward, and the next peg rod 4d The peg rod 4b and the peg rod 4d are moved to the position of the rod 4b, and the distance between the peg rod 4b and the peg rod 4d is increased. This operation is repeated one after another to sequentially move the glass plates and the like to be transferred onto the peg rod 4 from the right to the left in FIG.

Incidentally, a motor capable of forward and reverse rotation may be used in place of the two rod cylinders 16, and the pushing tool 1
4 is not limited to both rod cylinders 16.
Also, instead of the peg rod 4, an endless chain 3,
It is possible to attach a suitable conveying jig to 3' and transfer objects that fit the conveying jig.

As described above, according to the present invention, by increasing the interval between the transport jigs at the receiving part and the dispensing part, and by reducing the interval between the transport jigs in the transport route between them, dispensing and receiving can be ensured. It goes without saying that this method does not cause any damage or damage to the transported objects, but it also has the effect of increasing the storage capacity of the transport route in areas where the distance between the transport jigs is small and making effective use of that route. .
