Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cargo handling device mounted on a forklift vehicle or the like.

BACKGROUND ART As shown in FIG. 5, a face 4 equipped with a clamper 3 for a sheet pallet 2 is movably provided above a platen 1, and this face 4 is connected to a base 6 via a link 5. A cylinder 7 is pivotally connected between the link mechanism 5 and the base 6, and by expanding and contracting the cylinder 7, the face 4 is moved back and forth, so that the cargo A on the sheet pallet 2 is moved back and forth along the platen 1. A telescoping cargo handling device is known.

Problems to be solved by the invention Since the stroke end on the side of the base 6 of the face 4, that is, the backward stop position, is regulated by the shape of the link mechanism 5, etc., when handling cargo A of different sizes, it is difficult to Baggage A pulled in too much
Platen 1 may pop out, and when loading cargo in such conditions, the tip 1a of platen 1 may interfere with and damage the cargo A' that is already placed at the back, as shown in Figure 5. Sometimes.

Means and operation for solving the problem A pair of left and right guide rails are connected by a horizontal frame to form a base, and the ends of the links constituting the link mechanism are pivotally connected to rollers that slide along the guide rails, A plate that restricts the upward movement of the roller is provided at the bottom of the screw rod screwed into the screw hole of the horizontal frame, and the roller can be moved by tightening and loosening the screw rod to move the plate up and down. Regulates the upward movement and the expansion and contraction stroke of the link,
This allows the rearward stop position of the face to be changed and set as desired.

Example The link mechanism 5 includes the first to fourth links 5 ₁ , 5 ₂ , 5
₃ and 5 ₄ , the first and second links 5 ₁ and 5 ₂ are pivotally connected to the face 4 and the base 6 and are pivotally connected by a pin 8, and the third and fourth links 5 ₃ and 5 ₄ are pivotally connected by a pin 9, and the fourth link ₅₄ is connected to a roller 11 that can swing freely along a guide rail 10 of the base 6, and a cylinder is connected between the third link ₅₃ and the base 6. 7 are pivotally connected.

A plate 12 that restricts upward movement of the fourth link ₅₄ is provided on the base 6 and can be adjusted to move vertically.

That is, as shown in FIG. 1, the base 6 has a pair of left and right guide rails 10 connected by an upper horizontal frame 13, and screw holes
A screw rod 15 having a plate 12 is screwed into the screw rod 4 in the vertical direction, and the screw portion 1
A lock nut 16 is screwed onto 5a.

A shaft 17 connects the left and right fourth links ₅₄ .

When the face 4 is moved backward, the roller 11 of the fourth link ₅₄ slides up and down along the guide rail 10, and the fourth link ₅₄ comes into contact with the plate 12 to reach the backward stop position. The backward stop position of the face 4 can be changed by moving the plate 12 up and down by loosening the lock nut 16 and rotating the screw rod 15. For example, the backward stopping position of the face 4 can be changed from the state shown in FIG. 2 to the position shown in FIG. 4, and set the backward stop position of the face 4 according to the length of the load A so that the tip of the load A matches the tip 1a of the platen 1, then the load can be placed. During work, the tip 1a of the platen 1 does not interfere with the baggage A' already placed.

Effects of the invention The backward stop position of the face 4 is determined by the expansion and contraction stroke of the link mechanism 5, and the expansion and contraction stroke of the link mechanism 5 is determined by the stroke of the roller 11 moving upward along the guide rail 10. The upward stroke is regulated by the plate 12, and the vertical position of the plate 12 is changed by tightening and loosening the threaded rod 16.

Therefore, the backward stop position of the face 4 can be changed arbitrarily by a simple operation of loosening the lock nut 16, tightening the screw rod 16, and loosening it. It is possible to set the backward stop position of the load so that the load coincides with the tip 1a of the platen 1, so that the tip 1a of the platen 1 does not interfere with the load that has already been placed during loading work, thereby preventing damage to the load. Never.
