JPH10194659A - Box bowl transfer device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To certainly carry a box bowl pillar to a specified position and unload it without dropping a box bowl on the bottom step as it is supported by a projected piece by forming and inserting the projected piece in a clearance on lower ends of two piece of clamping plates, that is, on a lower side of the box bowl. SOLUTION: A box bowl pillar standing on a placing surface by motion of a carrier elevating device in a state where a pair of clamping plates 15 is opened in moved in a direction where the clamping plates narrow a corresponding interval by actuating a pneumatic cylinder 20 after lowering lower end edges of the clamping plates 15 to a position of the placing surface by putting it between a pair of the clamping plates 15. The box blow pillar is clamped by elastically pressing a rubber pad 15a, and simultaneously, a projected piece 30 introduces in a clearance below a box bowl on the bottom step of the box bowl pillar from both sides. When a clamping device 10 is lifted up by driving the carrier elevating device, the box bowl on the bottom step is supported from below by the projected piece 30, and it is possible to prevent leaving it behind or dropping it in the middle of transportation.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION As shown in FIG. 1, the present invention uses a sagger a made of refractory material and having an H-shaped cross-section in which a horizontal plate c is integrally provided at the center of a vertical plate b on both sides. When stacking saggers stacked in columns in a multi-tiered manner by holding a base of ceramic products such as tiles, or unloading saggers stacked in a multi-tiered stack containing baked products. The present invention relates to a sagger transfer device used at the time.

[0002]

2. Description of the Related Art The present applicant has filed a patent application for a sagger transfer device for transferring a sagger column from both sides by sandwiching plates, and has been published as Japanese Patent Application Laid-Open No. 63-185796.

[0003] In this sagger transfer device, the sagger is sandwiched between two holding plates having rubber pads stretched on the inner surface, and the sagger is lifted and transferred to a predetermined position.

[0004]

However, as the number of uses increases, the sagger gradually expands and becomes larger in size.
Normally, the size becomes larger by about 2 to 5 mm for about 100 times.

[0005] Therefore, if the sagger, which has been used less and has a smaller size, is located at the bottom of the sagger, even if the rubber pad is stretched, it cannot be clamped by the clamping plate and is left at that position. In the worst case, although they were lifted together, when they were brought to the unloading position, they fell and were damaged due to weak clamping force, and the shackle post was lowered on top of it, causing the In addition to falling, the fired product and the base may be damaged as well as the sagger.

In order to prevent this, a method of increasing the thickness of the lowermost portion of the rubber pad attached to the holding plate has been adopted, but the effect has not always been sufficiently enhanced.

[0007]

Means for Solving the Problems, Actions and Effects As means for solving such problems, the invention of claim 1 is based on the invention that the lowermost sagger of the sagger is provided at the lower ends of two holding plates. Is formed in the gap on the lower side of the sagger, even if the lowermost sagger of the sagger is not sufficiently clamped by the clamping plate. The lowermost sagger has the effect of being able to securely carry the sagger to a predetermined position and drop it down without being supported by the projecting piece and falling. Item 1
In the invention according to the invention, the protrusion is formed into a screw rod which is screwed to the two holding plates so that the protrusion amount can be freely adjusted, so that the protrusion amount can be adjusted according to the size and shape of the sagger to transfer the protrusion more reliably. effective.

In the present invention, a protruding piece is inserted into a gap below the lowermost sagger, so that an H is used as shown in FIG.
It can be applied only to sagger a
Obviously, it can be applied only when clamping from the length direction.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 2 to 4, reference numeral 10 denotes a clamping device for transporting the sagger column by a transport lifting device (not shown). A pair of elongated guide plates 12 are fixed at intervals, and attached to the rear surface of a pair of holding plate mounting bodies 14 on horizontal rods 13 fixed at both upper and lower ends of the guide plates 12 through both guide plates 12. The cylindrical body 14a is fitted so as to be freely slidable, and a clamping plate 15 having a rubber pad 15a adhered to a corresponding surface for clamping the sagger is attached to the front surface of each clamping plate mounting body 14, and the clamping plate 15 is moved in the corresponding direction. The left and right ends of each holding plate mounting body 14 form a pair on the left and right sides, respectively.
An inwardly inclined guide groove 18 inclined at 0 ° is formed symmetrically, and a downward pneumatic cylinder 20 is mounted on the upper surface of the mounting plate 11, and projects downward through the mounting plate 11. A sliding body 22 is attached to a guide key 24 formed on a corresponding surface of the guide plate 12 so as to be movable up and down at the tip of the piston rod 21. An operation plate 25 which can be moved up and down is attached to the rear surface side of the guide groove 18 of the holding body mounting body 14, and the roller 2
7 are axially supported symmetrically, and each roller is fitted in a corresponding guide groove 18.

The above is a known holding device. In the present embodiment, a plate-shaped protruding piece 30 is fixed to the lower end edges of the pair of holding plates 15 inward.

Next, the operation of this embodiment will be described.

As shown in FIG. 4, when the holding device 10 is in a state in which the roller 27 is located at the upper end of the guide groove 18 and the pair of holding plates 15 are opened due to the contraction of the piston rod 21 of the pneumatic cylinder 20. As shown in FIG. 5, the sagger pillar d standing on the mounting surface by the movement of the transport elevating device is inserted between the pair of holding plates 15, and the lower end edge of the holding plate 15 is substantially in contact with the mounting surface e. After being lowered to the position, the piston rod 21 of the pneumatic cylinder 20 is extended and the operation plate 25 is lowered, and as shown in FIG.
Is lowered along the guide groove, as shown in FIG. 6, the pair of holding plates 15 move in the direction of narrowing the corresponding gap to elastically compress the rubber pad 15a to pinch the sagger d, and The pieces 30 enter the gaps below the lowermost sagger a of the sagger pillar d from both sides.

Therefore, when the holding device 10 is lifted by the drive of the transport elevating device, the projecting piece 30 supports the lowermost sagger a from below.

For this reason, even if the size of the lowermost sagger a is small and the sagger a is not sufficiently fastened by the rubber pad 15a, the sagger a may be left on the mounting surface or fall during the transportation. It is surely prevented.

When the sagger d is carried to a predetermined position by the transport elevating device and placed, the piston rod 21 of the pneumatic cylinder 20 contracts as shown in FIG. The projecting piece 30 spreads out and retreats from the lower gap of the lowermost sagger a, and can be lifted only by the holding device 10.

The protruding piece 30 is changed to the above-mentioned plate-like one, and as shown in FIG. 7, is formed into a threaded rod having a sharp point, and is screwed into a screw hole 32 formed at the lower end of the holding plate 15. , May be fixed by a nut 32. In this form, sagger a
The screwing amount of the projecting piece 30 can be adjusted according to the size and shape of the projection piece 30. Further, in this embodiment, it is better to provide two or more protruding pieces 30 on one holding plate 15.

Further, the opening and closing mechanism of the holding plate 15 is not limited to the one described in the above-mentioned embodiment, and other configurations can be adopted.
