Are provided so as to be slidable in the front and rear direction in the horizontal direction (left and right directions in FIGS. 3 and 4) along with the air cylinder 28 for driving the interleaf press 26 in the front and rear direction in the horizontal direction. The above-described cutter 10 is provided at a position adjacent to the leading end of the horizontal portion of the slip sheet guide 24b so as to be movable at right angles to the slip sheet feeding direction. An air cylinder 31 reciprocates the cutter 10.

The chuck 9 is a chuck lifting / lowering traveling device 3
2 is provided. The traveling table 3 is capable of reciprocatingly traveling in the side-by-side direction (the left-right direction in FIG. 2) of the molded products 8 along the traveling rail 34 provided on the beam 33.

The chuck 9 is attached to a piston rod 37a of the air cylinder 37.

Next, the operation of the slip sheet supply device 1 will be described. First, as a preparation work, an operator sets the slip sheet roll 3 on the support shaft 4, passes the slip sheet 2 through the slip sheet feed roller 5, the tension roller 11, and the slip sheet return roller 7.
Its tip is slightly protruded above the space between the slip guides 24a and 24b as shown in FIG. Note that the interleaf return rollers 7a,
When the slip sheet 2 is passed through the gap 7b, the air cylinder 23 is extended to separate the slip sheet return roller 7b from the slip sheet return roller 7a, and after passing, the air cylinder 23 is contracted to return the slip sheet return roller 7b to slip sheet return. The interleaf paper 2 is pinched by being pressed against the roller 7a. Thus, the leading end of the slip sheet 2 is set immediately below the initial position of the chuck 9.

A molded product (in the case of a channel steel in the illustrated example) 8 formed by a roll forming machine is kicked laterally from a run-out table (not shown) after cutting during running, and is fed laterally by a conveyor 38.
It is fed laterally above, and is stacked on a product pallet 39 by a molded product stacking device (not shown) at the leading end of the horizontal feed conveyor 38. 1 and 2 show the molded product 8
Are arranged on the product pallet 39 with only one stage and a front posture (a U-shaped posture is referred to as a front surface) at intervals. At this stage, a slip sheet supply signal is issued. Then, the chuck 9 waiting at the initial position in FIG. 2 is lowered (chuck down) by the driving of the air cylinder 37, and then closed to chuck the tip of the vertical slip sheet 2 (chuck closed). Rises while chucking the slip sheet 2 (chuck rises), and then travels to the left in FIG. 2 (chuck travel) by driving the rodless air cylinder 36.
And then descend (chuck descend). FIG. 1 illustrates this stage. During this time, the slack of the slip sheet 2 is constantly removed by controlling the feed amount of the slip sheet feed roller 5. When the next molded article 8 is sent in the state shown in FIG. 1, the next three molded articles 8 are stacked in a face-down position as shown in FIG. To fit.
Then, as shown in the figure, the slip sheet 2 is interposed between the upper and lower molded products 8 fitted to each other. In this case, the interleaf 2 is pushed down by the molded product 8 in the back position placed on the upper side, and is interposed in the corrugation between the molded products 8 fitted to each other. If the tension is not applied, the slip sheet 2 becomes slack, and the slip sheet is not supplied smoothly. However, since the tension roller 11 and the slip sheet feed roller 5 cooperate to keep the slip sheet 2 at a constant tension, a smooth slip sheet supply is performed.

Thereafter, the chuck 9 is opened to release the slip sheet 2 (chuck open), rise (chuck rise), and then, as shown in FIG.
(Return to chuck). Then,
The air cylinder 28 operates to move the slip sheet holder 26 horizontally to hold the slip sheet 2 on the horizontal portion of the slip sheet guide 24b. Next, the air cylinder 31 for the cutter 10 is extended, and the cutter 10 cuts the slip sheet 2. Since the interleaf press 26 is normally retracted, it does not hinder the chucking operation of the front end of the interleaf by the chuck 9 and presses the interleaf 26 to make the cutting by the cutter 10 smooth. The interleaf 2 may be cut by the cutter 10 while the chuck 9 is chucking the interleaf 2.

After the cutter 10 and the interleaf press 26 return, the clutch 20 is engaged, the return drive motor 6 is operated, the interleaf return roller 7 rotates in the reverse direction, and the interleaf 2 is slightly returned. As a result, the leading end of the slip sheet 2 is
From the state of lying down on the top, as shown in FIG. 2, the posture is such that it stands vertically between the two slip sheet guides 24a and 24b. Therefore, it is possible to chuck the slip sheet 2 by the chuck 9 in the next step.

In the same manner, each time one section of the molded article 8 (three in the illustrated example: each of the front and back sides is one step) is arranged side by side at intervals, the slip sheet feeding operation, that is, Various operations such as chuck lowering, chuck closing, chuck raising, chuck running, chuck lowering from the initial position, chuck opening, chuck raising, chuck returning, and cutting of the slip sheet by the cutter 10 are performed. Thereby, as shown in FIG.
Is interposed, and stacking is performed.

Although the embodiment has been described in connection with the case of stacking molded products having a groove-shaped cross section, the cross-sectional shape itself of the molded product is arbitrary.

[0018]

According to the slip sheet supply device of the present invention, despite the fact that the slip sheet for preventing damage to the molded article is flexible and not easy to handle, the slip sheet is automatically inserted between the stacked molded articles. The supply operation can be performed smoothly and efficiently.

According to the second aspect, the tension roller cooperates with the interleaf feed roller to prevent the interleaf from being loosened while maintaining the interleaf at a constant tension. Even in the case of flexing, it is possible to prevent the smoothness of interleaf paper supply from being impaired.

According to the third aspect of the present invention, the slipping sheet presser, which can advance and retreat in the horizontal direction and press the slipping sheet on the horizontal portion of the slipping sheet guide, does not hinder the chucking operation of the tip of the slipping sheet by the chuck. Cutting can be performed smoothly. In addition, the mechanism for holding the slip sheet is simple.
