Abstract

PURPOSE:To assuredly move a sheet to its destination by providing pivoting members for pivoting at least two spit members in such a manner as to be removed apart and brought close to each other. CONSTITUTION:With a piston 21 of an air cylinder 2 pulled in, two spits 42, 52 are retained parallel to each other. When a sheet W is pierced with the spits 42, 52 and the air cylinder 2 is operated, the piston 21 is pushed downward, so that the spit holders 41, 51 are pivoted to outstretch the forward end portions of two spits. As tension such that the spit restores to its initial state works upon the sheet W itself, the sheet W is firmly held by two spits 42, 52. After the sheet is transported to its destination, the spits 42, 52 are restored to be parallel to each other, so that the sheet W is dropped by its dead load.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet holder for skewering and holding sheets such as plastic sheets and soft boards.

Conventionally, small soft sheets have been carried into molds etc. manually, and large sheets have been carried in by conveyors. When a sheet of small objects or a sheet of a person has a complicated shape or requires accurate positioning, the f1 operation has to be performed manually.

The present invention provides a sheet holder that automates sheet loading. With the five sheet retainers of the present invention, the held position of the sheet does not move, so positioning the sheet on the mold etc. becomes easy.

The seat holder of the present invention includes a base, an intermediate member having at least two rod-shaped tip portions that are swingably held on the base, and a direction in which the tip portions of the two intermediate members are moved away from each other without making any concessions. It is characterized by comprising a swinging member held at a base that swings in the approaching direction.

In the sheet holder of the present invention, the rod-shaped tips of at least two middle members constituting the tool are inserted into the sheet holder, and the skewered tips are widened and narrowed to each other. The sheet is held at the tip of the middle member. The sheet holder of the present invention only holds and removes the sheet, and the sheet is moved using a normal loading/unloading device that can move vertically, horizontally, etc. It is used by being attached to the end of the arm of the device.

If the sheet for small items can have a skewer hole in the center, - number of sheet holders of the present invention may be used, but usually two or more sheet holders are fixed to the arm of the carrying device. The sheet is conveyed while being held by two or more sheet holders of the present invention.

The number of middle members constituting the seat holder of the present invention is small (two
pcs are required. In practice, two or three pieces are preferable.

This middle member may be an integral piece including a rod-shaped tip, but it may also be configured to be detachable using a rod-shaped skewer and a base, screws, etc. The diameter of the tip of the middle member may be made thinner toward the tip, or the surface of the tip may be coated with a material having low frictional resistance. This facilitates the departure of Sea 1~. Conversely, the unevenness may form a vortex on the tip of the middle member or on the outer periphery of the skewer. In this case, the sheet is strongly held. The at least two middle members can be swung using a known link mechanism, such as a bottle, etc., and held in a freely swingable manner, and the middle members can be oscillated by applying a rotational moment to the middle members.

As the rotating seven-men 1-, a one-horn cylinder or a drive motor can be used.

In the sheet holder of the present invention, it is preferable to provide a sweeping member in order to remove the skewered sheet. When the tip of the middle member is pulled out from 1~, the sheet that supports the sheet J (-1 at least 1:) is in contact with the sheet 1~ at a symmetrical position centered on the tip of the two middle members, and the sheet is It is a yoke that presses down.

In this case, the elongated hole into which the tip of the middle member is inserted b) is suitable for use with a cutting board, but it does not necessarily have to be completely rooted.

The drive member moves the wiper member and the middle member relative to each other in the approximate axial direction of the tip of the sleeve, presses the sheet 1- with the wiper member, pulls the tip of the middle member behind the sheet, and removes the book. There is a device C that allows the sheet to be removed from the sheet holder. As this driving member, an air cylinder or a driving motor can be used. As a mechanism for relatively moving the sweeping member in the approximately axial direction of the tip of the middle member, the piston of an air cylinder may be arranged parallel to the axis of a skewer, or a known mechanism such as a pantograph may be employed.

In the sheet holder of the present invention, the sheet is held by at least two middle members of the sheet holder skewering the sheet 1;
This is done by widening the tips of the A to move away from each other, or conversely narrowing them towards each other. Therefore, the sheet will not slip or shift while being held by the sheet holder, and the sheet can be reliably transferred to the desired location, making positioning easy. Also, since the sheets are skewered, it is possible to hold one sheet or two or more sheets at the same time.

Examples will be explained below.

Example 1 The seat retaining device of the first example is shown in Fig. 1 Jj J and Fig. 2.
As shown in the figure.

This sheet holding shrine consists of a fixing plate 1 fixed to the arm of the transfer device, a cylinder 2 fixed to the fixing device 1 with noars 1 to 11, and a horn cylinder 2. fixed to the distal end: a base 3; and two small parts 44/1.j, which are swingably held on the base 3; ', ), the air cylinder 2
It consists of a driving pin 22 fixed to the tip of a piston 21.

The upper part of the base 3 has a central hole in the bottom [it is like a lid with an opening at the end, and the tip of the first cylinder 2 is fixed here, and the tip of the piston 21 protrudes from the center hole in the bottom or above the I-5. ing. There are wall-like protrusions 31.32 on both sides of the medium hole of the base 3 that extend to 1.32. Small section 444. b Dog-shaped skewer small lug'I-1.

Take 51 and 42. This skewer holder 31 also has a pin hole at the corner of the middle part (L), and the protrusions 31, 32 and 33, 34 (-) of the base 3 are swingably supported by this pin hole. A deep hole into which the skewer 4.2.52 is inserted is formed at one end of .51, into which the 8 skewers 42.52 are inserted and firmly fixed with screws on the side wall.At the other end is a U-shaped groove. A drive pin 22 fixed to the tip of the piston 21 is inserted into this groove.

The L7 cylinder 2 is of a reciprocating type, and by pushing down the screws 1 to 21, the driving pin 22 fixed to the tip of the cylinder 2 moves the skewer holder 41°51 through its engaging U-shaped groove. push it downward through the As a result, the skewer holder 41.51 swings about the bin 33.34 as the axis of rotation, and the tips of the skewers 42.52 open in a direction that moves away from each other. Push the piston 21 upwards and release the skewer holder 41.
．． 51 swings in the opposite direction, and the tips of the skewers 42 and 52 move in a direction closer to the slope.

The sheet holder of this embodiment has the above structure.

As shown in FIG. 1, the function of this sheet holder is to first keep the piston 21 of the air cylinder 2 in a retracted state, and hold the two skewers 42 and 52 in parallel positions.
Ru. In this state, it is identified by an arm of a transfer device (not shown) and carried to a predetermined position 191 of the sheet W to be transferred. The sheet W is transferred to 1 of the table I3, and this table 8 is provided with elongated holes 131 and B2 into which a skewer is inserted. In this state, the skewer 42.
