Furthermore, with respect to the pivot shaft 3a of the rotating roll fitting 3 for clamping, the shaft body 4 for clamping operation is
is mounted horizontally, and the tip end portion of the operating shaft 4 is passed through a guide hole 2d vertically opened in the central portion of the oblique guide plate portion 2b. It is configured so that it protrudes in the opposite direction.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is applicable to thin plate materials such as printed circuit boards, thin metal plates, and thin plastic plates. When moving the item, hold the upper edge of the board and suspend it. This relates to clamps that can be used in automatic manufacturing machines, etc. It is intended for integration into conveyor systems that carry

0002

[Conventional technology]

Conventional clamps of this type have been clip-shaped and clamped using spring force. In other words, a thin plate-like product can be clamped using a clip fitting that expands against the force of a spring. It was intended to be used for transportation.

0003

[Problem that the idea aims to solve]

With conventional clamps such as those mentioned above, the weight of the thin plate product to be transferred is If it is heavy, the weight may overcome the spring force and cause an accidental fall. There was that. Furthermore, such a clip-like material makes it difficult to attach and transport. It is difficult to automate subsequent unpinching, and this usually has to be done manually. It was.

0004

[Means to solve the problem]

The present invention is a diagonal guide plate having a vertical plate portion 1a and an inclined surface that spreads upward. part 2b with its lower edge against the lower end of the vertical plate part 1a at a predetermined clamping interval M. while keeping the upper ends of the vertical plate part 1a and the oblique guide plate part 2b facing each other. The part is closed by providing the required top plate member, and the hanging shaft 3b is fixed in the center part. Clamping rolls 3c are freely rotatably attached to both sides of the pivot 3a, and the hanging shaft is 3b penetrates the top plate member and protrudes so as to be freely raised and lowered, and the holding roll 3c A coil sprocket for applying force to press the above-mentioned clamping interval M portion. A ring 3d is interposed on the hanging shaft 3b, and the holding rotating roll metal Attach the clamping operation shaft 4 horizontally to the pivot 3a of the tool 3, and , the part near the tip of the operating shaft 4 is vertically attached to the center part of the oblique guide plate part 2b. By penetrating the guide hole 2d opened in the direction, it protrudes outward so that it can be raised and lowered. The present invention relates to a clamp characterized by:

[0005]

【Example】

In the figure, reference numeral 1 denotes a base frame with an inverted L-shape on the side, which includes a vertical plate portion 1a and a vertical plate portion 1a. It consists of a horizontal plate part 1b protruding forward from the upper edge of the straight plate part.

[0006] Reference numeral 2 denotes a guide plate, which includes a top plate portion 2a that overlaps with the horizontal plate portion 1b, and a guide plate that overlaps the horizontal plate portion 1b. The upper end is located at the front edge of the plate part 1b, and the lower end is located at the lower end of the vertical plate part 1a for clamping. and a diagonal guide plate portion 2b positioned at a distance M from each other. And the current The oblique guide plate portion 2b has an inclined surface that widens upward.

[0007] Reference numeral 3 denotes a rotating roll fitting for clamping, which is constructed as follows. 3a is the center It is a pivot with a hanging shaft 3b fixedly attached to the shaft, and clamps are provided on both sides of the pivot 3a. A roll 3c is attached for free rotation. The shaft body 3b is It penetrates the horizontal plate part 1b and the top plate part 2a and protrudes so as to be able to rise and fall freely. 1 c and 2c are for the suspension shaft 3b bored in the horizontal plate part 1b and the top plate part 2a. This figure shows the through hole. 3d is a coil spring interposed in the hanging shaft 3b. In such a case, the clamping roll 3c is pressed against the clamping interval M portion described above. It gives power.

[0008] 4 is attached horizontally to the pivot 3a of the rotating roll fitting 3 for clamping. This is a shaft for clamping operation. The operating shaft 4 has a portion near its tip, In the guide plate 2 described above, the guide plate 2 has a longitudinally opened guide plate in the center part of the diagonal guide plate portion 2b. By passing through the side hole 2d, it is made to protrude outward so that it can be raised and lowered.

[0009] In the state shown in Fig. 5, if the operating shaft 4 is pushed up, the rotating roll metal The entire tool 3 rises. At this time, the clamping roll 3c depends on the coil spring 3d. Based on the pressing force, the guide plate 2 is pressed against the inner surface of the diagonal guide plate portion 2b. rise in a state of Therefore, as shown by the chain line in FIG. 3c and the vertical plate portion 1a in the base frame 1, the angle of inclination of the oblique guide plate portion 2b and It will be held accordingly. In this invention, the top plate part 2a is moved by the conveyor. It is used by attaching it to the feed line.

0010 When using the present invention to clamp and transfer a thin plate-like product P, press the operating shaft 4. Then, a gap of a predetermined width is formed between the clamping roll 3c and the vertical plate portion 1a. child In this state, the upper end of the thin plate-like product P is thrust into the gap. After that, If the push-up on the operating shaft 4 is released and the clamping roll 3c is lowered, The thin plate-shaped product P is held between the holding roll 3c and the vertical plate portion 1a, and is in a suspended state. It is maintained. At this time, the weight of the thin plate-like product P should be reduced by pulling down the clamping roll 3c. Therefore, the clamping force for the thin plate-like product P is further increased. It will be.

[0011] In addition, when inserting the thin plate-shaped product P, do not push up the operating shaft 4. Insert the upper end of the thin plate-like product P between the clamping roll 3c and the vertical plate portion 1a. It is also possible to insert it.

0012 To release the grip on the thin plate-shaped product P, push up the operating shaft 4 to release the grip. All you have to do is raise the roll 3c. Accordingly, the clamping of the thin plate-like product P is It will be released and fall downward. Then, press against the operating shaft 4. By using an appropriate cam mechanism, the lifting operation can be automatically performed to release the jamming. It is possible to aim for

[0013]

[Effect of the idea]

In the present invention, between the clamping roll 3c and the vertical plate part 1a, the upper end of the thin plate-like product P is By thrusting the thin plate-like product P between the clamping roll 3c and the vertical plate part 1 It is extremely strong because it is configured so that it can be maintained in a suspended state based on the clamping with a. This means that the clamping force can be obtained. In other words, the weight of the thin plate-like product P is It acts as a force that tries to pull down the roll 3c, and therefore, the force applied to the thin plate-like product P is The clamping force will be further increased.

[0014] Furthermore, the present invention provides for a clamping operation with respect to the pivot shaft 3a of the rotating roll fitting 3 for clamping. Attach the operating shaft 4 horizontally, and move the tip of the operating shaft 4 toward the front. A guide hole 2d formed vertically in the center portion of the diagonal guide plate portion 2b is passed through. Accordingly, the thin plate-shaped product P The clamping operation and the clamping release operation can be achieved very easily.

[0015] In other words, if it is a clip-like item as in the past, it is difficult to attach and solve the problem. The removal operation had to rely on manual work, but in this invention, Since it is performed based on the raising and lowering operation of the operating shaft 4, for example, it can be performed based on the use of a cam mechanism. It becomes possible to automatically attach and release the attachment. In other words, this invention This is the best clamp for use in dynamic transfer lines.
