Description Material supply shelf device Technical field

The present invention relates to a material supply rack device that stores a plurality of types of materials (plate materials) in a plurality of stages for each type and stores them on shelves, automatically takes out the plate materials from each stage of the shelves, and carries them out to the next process. . Background art

Conventionally, there is an example as shown in FIG. 9 as a material supply shelf device that stores a plurality of types of plate materials, takes out necessary plate materials one by one, and carries them out to a processing process. In Fig. 9 (a), various plate materials are placed on the shelves 1 1 1 1 1 3 a, 1 1 3 b, 1

13c and 113d are stored separately for each type.

On the side of the shelf 1 1 1, it moves up and down along the side of the shelf 1 1 1, and the plate materials stored in each stage 105 a, 105 b. 105 c, 105 d A single sheet take-out means 120 for taking out the sheets one by one is provided.

The single-sheet picking means 120 is provided with a suction pad 125 for sucking a material.

Further, a transport conveyor 150 is provided adjacent to the material supply shelf device 110 to carry out the plate material in the next process such as bending.

The process from taking out the sheet material to carrying it out will be described.

Fig. 9 (a) shows the shelf 1 1 1, for example, in order to take out the plate 1 105 c of step 1 13 c, take out the single sheet taking means 1 20 next to the step 1 13 c along the side of the shelf. It has moved.

Fig. 9 (Mouth) shows the material in which the single-sheet collecting means 1 This shows the state in which it was taken.

In this state, the suction section 125 descends to suck the plate material and take one sheet. Fig. 9 (c) shows a state in which the sheet material is taken out from the state of Fig. 9 (mouth), the single sheet take-out means 120 is lowered, and the sucked sheet material is transferred onto the conveyor 150. I have.

The plate material transferred onto the conveyor 150 is carried out to the next step by a conveyor or the like of the conveyor 150.

In this way, the required plate material is automatically carried out to the next process from the plate material stored in each stage of the shelf.

In this way, the shelves are divided into a plurality of stages and stored in each material size, plate thickness, and material, then taken out one by one and supplied to punching and bending machines, etc., and set production for each product to be assembled Is widely adopted because it can be used.

However, in such a structure, the material taking-out means had to go to each stage to collect the material and transport it to the carry-out conveyor, which required a long operation time.

In order to increase the speed of the single-sheet take-up means, the size of the drive system also increased, and the strength of the rails was limited accordingly.

In order to store the materials on the shelves, they are stored one by one using a single-sheet picking means, or stored directly on each stage using a forklift, etc., and stored one by one. Machining had to be interrupted and positioning was difficult with a forklift. If the positioning is misaligned, it may cause a mistake in taking one sheet. Disclosure of the invention

In view of the above technical problems, an object of the present invention is to provide a material supply shelf device that can store a plurality of types of materials for each stage and can carry out necessary materials to the next process in a short time. The technical gist of the present invention is to provide a single-sheet collecting means for providing a single material from each stage of a shelf, comprising a shelf capable of storing a plurality of types of materials for each stage, and a material from the single-sheet collecting means. A take-out means for receiving and carrying out to the next process is provided along the side of the shelf, and each can be moved up and down, and control is made so that the take-out means takes out the material taken by the single-sheet take-up unit. It is in.

The single-sheet take-up means and the unloading means move up and down with each other, and deliver the material at an arbitrary position on the side of the shelf close to each other, so that the moving distance of the single-sheet take-up means is greater than when the unloading means does not move. Will be shorter.

As a result, it is possible to reduce the time required for the single-sheet collecting means to remove the material from the shelf and transfer it to the carrying-out means.

Here, the vertical movement of the unloading means and the operation of the single-sheet pick-up means taking out the material and moving in the horizontal direction are controlled in conjunction with each other, and while the unloading means is being transferred to the conveyor, the single-sheet pick-up means You can go to get the material.

Also, since the height of the unloading means is not fixed to the height of the pass line of the incoming conveyor in the next process, the shelf on which the materials are stored is positioned lower than the pass line of the incoming conveyor in the next process. Can also be provided.

—The sheet take-out means and the unloading means have rails so that they can move up and down on the same track.

Since the single sheet take-out means and the unloading means move up and down on the same track, guide rails and racks for up and down movement can be shared, and the number of parts can be reduced.

Also, since the drive parts can be shared, the maintainability is good.

Furthermore, the apparatus becomes compact by providing a single-sheet pick-up unit above the unloading unit.

—The sheet taking means includes a base connected to a track for vertical movement, a first arm which can be slid in a substantially horizontal direction at a lower portion of the base, and a lower portion at a lower portion of the first arm. Second arm that can be slid horizontally in one or more stages The first arm is connected to the drive chain provided on the base part, and both ends of the driven chain provided on the first arm, which are once y between predetermined sprockets, are connected to the base part. The second arm is connected to the driven chain, and the lowermost arm such as the second arm is provided with material suction means.

When the base chain is driven, the first arm connected to this chain: π- slides.

Then, since the both ends of the driven chain provided on the first arm, which make one turn between predetermined sprockets, are fixedly connected to the base, the driven chain turns.

Since the lower second arm etc. are connected to this driven chain, the first arm

Slide horizontally at twice the speed of the camera.

That is, when the first arm slides, the second arm connected to the first arm slides accordingly, so the slide speed of the second arm is added to the slide speed of the first arm. Will be done.

Therefore, the arm provided with the material suction section can be easily moved at high speed, which is effective in shortening the material removal time.

This arm mechanism may have a structure provided in a plurality of stages in the frontage direction of the shelf, or a structure in which a plurality of frames or flat plates are stacked instead of the arm.

In the material supply shelf apparatus of the present invention, when the unloading means delivers the material to the next-stage carry-in conveyor while the one-sheet picking means is taking out the material, and the one-sheet picking means takes out the material from the shelf, At that time, the unloading time is shortened because the unloading means is approaching and waiting for reception.

If a material supply means for the shelf is provided on the side of the shelf different from the side of the shelf provided with the unit for taking out and unloading the material, and the side of the shelf can be moved up and down, the material is unloaded from the shelf to the processing process. Even during this period, the material can be stored on the shelf as long as it does not interfere with the single-sheet pick-up means. This eliminates the need to stop the processing line to set up materials on shelves and enables continuous production.

In addition, material can be automatically stored on the shelf, and positioning is easy. Brief Description of Drawings

1 to 6 show an embodiment of a material supply shelf apparatus according to the present invention.

1 to 6, (a) is a side view of the material supply shelf device, and (mouth) is a perspective view.

For the sake of explanation, the conveyor for carrying in to the next step (processing step) is also shown in the perspective view.

In FIG. 1, the shelves 11 of the material supply shelves 10 are provided with stages 13a, 13b, 13c, 13d, and 13e. Classification Can be stored.

Figure 1 shows that stage 13a has no material to supply and only empty pallets 6 are stored, while stages 13b, 13c, 13d and 13e are on the palette respectively. Shows an example in which different kinds of materials 5b, 5c, 5d, and 5e are stored.

On one side of the shelf 11 1, a single-sheet picking-up means 20 and a carrying-out means 30 are provided vertically, and on the other side, a material storage means 40 is provided.

Thus, the apparatus 10 is compact by providing the single-sheet collecting means 20 above the carrying-out means 30. ^Five

—Sheet reloading means 20 and unloading means 30 move up and down along guide rails 15a and 15b provided on columns 12a and 12b of shelf 11 respectively. It is possible.

The drive structure of the single sheet take-out means and the unloading means will be described with reference to FIG.

Fig. 7 is a schematic diagram of the drive structure of the guide rail part for taking out one sheet and the unloading means. FIG.

In FIG. 7, for the sake of simplicity, illustrations other than the rack and pinion structure of the drive structure, the guide rollers, and the guide rails, as well as their mounting structures, are omitted.

In FIG. 1, the drive unit 21 on the column 12a side of the single-sheet pick-up means 20 is provided with a vertical drive motor 22a of the single-sheet pick-up means 20, and the motor 22a is a gear wheel. By rotating 2 2 b, the gear (pinion) 2 2 c rotates, and the single-sheet taking means moves along the rack 14 a.

The guide rails 15a are sandwiched between guide rollers 22e and 22f connected to the base portion 20a of the single-sheet pick-up means 20.

This driving force is also transmitted to the gear portion 21b on the side of the column 12b in FIG. 1 via a shaft 22d of a gear (pinion) 22c.

A rack and pinion structure and a guide roller are also provided in the gear portion 21b on the side of the support 12b.

In addition, in the drive section 31a of the unloading means 30 in FIG.

A vertical drive motor 32a is provided similarly to the drive unit 21a of 20.

By rotating the gear 32b by the 32a, the gear (pinion) 32c rotates, and the unloading means 30 moves along the rack 14a.

Since the carrying-out means 30 holds the guide rail 15a between the guide rollers 32e and 32f, it moves up and down along the guide rail 15a.

This driving force is also transmitted to the gear portion 31b on the side of the column 12b in FIG. 1 via the shaft 32d of the gear (pinion) 32c.

The single sheet take-out means 20 and the unloading means 30 move up and down on the same guide rails 15a, 15b and racks 14a, 14b.

The number of parts is smaller than in the case where separate tracks are provided separately, which has the effect of reducing equipment costs. Also, since the drive structure is the same and the components such as the guide rail motor can be shared, the maintainability of the device is good.

The single sheet take-out means 20 moves up and down along the side of the shelf 1 1, and takes out the material one by one by expanding and contracting the first and second arms 24 a and 24 b horizontally for taking out the material. 30 goes to receive the extracted material.

The structure in which the single-sheet taking-out means takes out the material will be described.

FIG. 8 is a schematic main part view of the vicinity of the material take-out arm of the single-sheet taking means.

Fig. 8 (a) shows the state where the take-out arm is contracted, and Fig. 8 (mouth) shows the state where the take-out arm is extended.

In FIG. 8A, a guide roller (not shown) for holding a track for up and down movement under the cover 20a of the single-sheet pick-up means 20 and a base unit having a drive unit (not shown) are provided. Two and three are provided.

A first arm 24a is provided below the base portion 23 via a slide member 26a provided in the longitudinal direction of the arm 24a.

Similarly, a second arm 24b is provided below the arm 24a via a slide member 26b. The arm 24b has a plurality of suction pads 25a for sucking the material. A provided material suction section 25 is provided.

A driving sprocket 27a and a driven sprocket 27b are provided on the base member 23, and a horn 28a is stretched.

Since the driving sprocket 27a is connected to a motor (not shown) and controlled in rotation, the drive of the chain 28a can be controlled.

The chain 28a is connected to an arm 24a provided at a lower portion via a connecting portion 29a.

Therefore, the arm 24a connected to the base 23 provided by the drive of the chain 28a is driven and slides. The driven first arm 24a is also provided with sprockets 27c and 27d, and a chain 28b is stretched.

Both ends of the chain 28 b are connected to the upper base 23 via a connecting portion 29 b.

As a result, when the first arm 24 a slides, both ends of the chain 28 b are connected to the base 23 by the connecting portion 29 b, so that they cannot move in the same direction as the arm 24 a. However, it will be pulled by the base part 23 and will rotate.

Since the chain X 28 b is connected to the arm 24 b via the connection portion 29 c, the key 24 b slides with the rotation of the chain 28 b. .

At this time, the arm between the base part 23 and the second arm 24 b provided with the material suction part 25 has the same structure as the first arm 24 a even if a plurality of arms are connected via a slide member. The arm 24b is driven by sliding.

Thus, the arm is driven by sliding the arm 24a closest to the base portion, and the arm mechanism expands and contracts with the second arm 24b provided with the material suction portion as the tip.

When the driving sprocket 27a rotates in the direction of the arrow from the state shown in Fig. 8 (a), the arm mechanism extends to the state shown in Fig. 8 (mouth), and the driving sprocket 27a moves from the state shown in Fig. 8 (mouth). When rotated in the direction of the arrow, the arm mechanism shrinks to the state shown in Fig. 8 (a).

To take out the material by the single-sheet take-up means, move the arm provided with the material suction section in this way onto the material stored on the shelf, then lower the single-sheet take-up means and adsorb the material with the suction pad This is done by raising the arm and contracting the arm mechanism.

This arm mechanism may have a structure in which a plurality of frames or flat plates are stacked instead of the arm. FIG. 2 shows a state in which the single-sheet picking means 20 is lowered to take out the material 5b of the step 13b from the state of FIG.

The single-sheet picking means 20 moves to a position where the material suction part 25 matches the frontage of the step 13b.

The unloading means 30 rises because the previously received material is moved to a position where the material can be received from the single-sheet pick-up means 20 after the material is transferred to the conveyor unit in the next process.

Further, the storage means 40 is moved by the storage section drive motor 42 by the y-chain 41, and is moved to the side of the step 13 a.

Next, as shown in FIG. 3, the arm mechanism of the single-sheet pick-up means 20 extends the second arm 24b into the step 13b, and moves the material suction portion 25 onto the material 5b. Then, the single-sheet pick-up means 20 descends, adsorbs one sheet of the material 5b with the suction pad 25a, and moves up.

The unloading means 30 moves to a material receiving position from the one-sheet taking means 20. By moving the unloading means 30 to the material receiving y position just below the single-sheet picking-up means 20, if the material temporarily drops from the single-sheet picking-up means 20, it is immediately received by the unloading means 30. Material scratches can be suppressed.

The empty pallet 6 is moved onto the storage section 40 by a moving device (not shown) provided in the storage section 40.

Next, as shown in FIG. 4, the single-sheet take-up means 20 descends after contracting the arm mechanism while adsorbing the single-taken material, and moves down the taken-out material 5 onto the carry-out means 30. Put on.

As described above, since the single-sheet picking means 20 and the unloading means 30 move up and down in conjunction with each other and deliver the material at an arbitrary position on the track close to each other, the single-sheet picking means 20 is There is no need to move to the pass line position of the loading conveyor 50 for the process. This shortens the movement distance from material removal to transfer, which has the effect of reducing time.

In addition, since the time for moving the material by suction is shortened, there is also an effect of reducing material drop failure.

Next, as shown in FIG. 5, the single sheet picking means 20 moves toward, for example, a picking-out position next to the step 13d.

At the same time, the unloading means 30 moves with the material 5 placed thereon toward the pass line position of the carry-in conveyor 50 in the next process.

As described above, the simultaneous operation of the single-sheet picking-up means 20 and the unloading means 30 can shorten the time until the material is unloaded.

The loading section 40 moves to a supply position beside the stage 13a for supplying the material 5a.

Next, as shown in FIG. 6, the single-sheet take-out means 20 extends the arm mechanism at the take-out position next to the step 13d, and moves the material suction part 25 upward to the material 5d.

Then, the single sheet picking means 20 descends, sucks the material 5d with the single sheet suction pad and moves upward, contracts the arm mechanism and removes it from the shelf.

The unloading means 30 unloads the material 5 by the roller conveyor 31 at the pass line position of the carry-in conveyor 50 in the next process.

In the storage means 40, the material 5a is moved to the stage 13a by a transfer device (not shown) provided in the storage means 40.

In this way, the material can be supplied to the material supply shelf at the same time as the material is taken out and taken out, so that continuous production can be performed without the need to stop the device.

In addition, the height of the bottom of the shelf can be set lower than the pass line of the carry-in conveyor of the next process within the movable range of the single-sheet pick-up means and the unloading means, so that the height of the whole equipment can be reduced and the material storage capacity can be reduced. Can be increased. If the amount or type of material is to be further increased, it can be easily handled by installing devices in parallel. For this reason, it can be easily added later. Industrial applicability
