Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an automatic chair laying machine for connecting a plurality of automatic chair laying machines for laying and collecting a large number of chairs at a conference hall, a gymnasium, etc. It relates to an interconnecting device.

[Conventional technology]

An example of this type of automatic chair laying machine is Japanese Patent Laid-Open No. 63-270.
From 006, an automatic laying machine as shown in FIG. 5 is known. That is, when recovering the chairs 1 arranged on the floor, the drive wheels 2 are operated to move the cart 10 backward, and the leg guides 9 are inserted between the legs of the chair 1. Chair detection switch is chair 1
Upon detecting the arrival of the lift-up position, the lift-up lever 3 (the position indicated by the alternate long and short dash line in Fig. 5) is activated and the horizontal bar between the front legs 1a
1B is lifted up and the lower end of the front leg 1a hits the tip of the leg mounting rail 4 and is tilted (the lifting lever 3 is in the solid line position in the figure). As a result, the horizontal bar 1b has the hook 5 with the tip in the vertical state.
And the hook 5 is pushed by one pitch above and is pressed by the hook 5, and the lift chain 6 is locked by the hook 5 in the process of operating for one link section, and further the front leg 1a is placed on the leg placement lever 4 and pushed. Raised, and the hoisting rail 3 reversely rotates to the standby position. Then, the trolley 10 is further advanced, the next chair 1 is locked in the same manner, and the lift chain 6
The chair 1 moves on the pitch, and in the following, a large number of chairs 1 are collected on the leg placement rail 4 while being locked by the hooks 5.

When the chair 1 is installed, the carriage 10 is moved forward, the lift chain 6 is reversed, and the leg mounting rail 4 is slid and dropped.

[Problems to be solved by the device]

Various automatic laying machines of this type are well known, and it is also well known to collect and lay a plurality of rows at the same time. However, there is a conventional method in which any number of machines can be laterally connected as needed. I didn't.

Therefore, an object of the present invention is to provide an interconnecting tool for an automatic chair laying machine, which connects two or more adjacent laying machines to each other.

[Means for Solving the Problems]

In order to achieve this object, the present invention provides a slide projecting on one side of an automatic chair laying machine along the longitudinal direction and a slide projecting on the other side of the automatic chair laying machine. And a slide guide formed in a groove shape that guides in the front-rear direction with a gap left on both upper and lower sides. A stopper for restraining the intruding slide is provided at the other end of the slide guide, and is formed at a corresponding position of the slide that comes into contact with the two through holes and the stopper that are separated from each other in the front-rear direction of the slide guide. Each of the through holes has a pin penetrating therethrough, and a slide guide is provided with a pin operating tool for interlocking and disengaging the two pins with the slide through hole.

[Action]

When connecting automatic chair laying machines, slide the slide of one chair automatic laying machine into the slide guide of one chair automatic laying machine with the pin raised with the pin operation tool. Guide along both sides and make contact with the stopper at the other end. Then, the pin operation tool is operated to lower the pin, and the slide through hole is penetrated and locked.

Even if the floor or the base of the laying machine is displaced, the gaps above and below the slide function as relief.

〔Example〕

Next, a case where the present invention is applied to the above-described automatic chair laying machine will be described.

FIG. 3 is a schematic plan view of the automatic chair laying machine shown in FIG. 5, in which a slide 20 is projectingly provided along one side of the trolley bottom, and a slide guide is provided along the other side. 30
Is projected.

The slide 20 has an L-shaped support plate 21 as shown in FIG.
Disc-shaped cam followers 22 are arranged in the front-rear direction on the upper surface of the, and through holes 23 of two pins are arranged on the upper surface 21a.

The slide guide 30 is formed in a groove having a rectangular cross section. That is, the cam follower 22 is inserted between the side plates 30a, 30b from one end to slide and guide in the front-rear direction,
An opening 31 is formed between the lower end of the side plate 30a and the lower surface 30b so that the support plate 21 can enter from the side. Side plate 3
Both ends of 0b are formed with inclined guide surfaces 30e facing outward so that the slide 20 can easily enter. At the other end of the slide guide 30, a plate-shaped stopper 32 for restraining the entering slide 20 is attached with one corner thereof supported by a hinge 32b. Also hinge 3
An operation lever 32a for opening and closing the stopper 32 is provided in a projecting manner at a diagonal corner of 2b.

On the upper surface 30c of the slide guide 30, two pins 45 passing through the through holes 35 spaced apart in the front-rear direction penetrate through the through holes 23 at the corresponding positions of the support plate 21 that abuts the stopper 32, and further on the lower surface. It can be fitted into a hole 33 formed in 30d. Furthermore, one end is hinged to the upper surface 30c and the other end is pin 45.
The arms 42.43 formed with locking pins 42a, 43a respectively provided on the heads of the upper ends of the arms, the link 44 pivotally connected to connect both arms 42, 43, and one arm 42 Pin operation tool 40 composed of the operation lever 42b installed above
Is provided.

The positions between the upper surface 30c and the lower surface 30d are set so as to leave gaps S1 and S2 that absorb mutual positional errors with respect to the support plate 21 and the cam follower 22 in the standard state (FIG. 2).

When the automatic chair laying machine 10 is connected to the adjacent one, the operation lever 42b of the pin operating tool 40 of the slide guide 30 of one automatic chair laying machine 10 is pulled to interlock and lift the pin 45. Then slide the slide 20 of the other laying machine to the arrow B
Intrude from the direction (Fig. 1). Thereby, the support plate 21
The cam follower 22 enters between the side plates 30a and 30b through the opening 31, and is guided toward the stopper 32 while sliding on the wall surface thereof. When the operation lever 32a is pressed while the tip of the support plate 21 is in contact with the stopper 32, the pin 45 causes the through hole 2 of the support plate 21 to pass.
It penetrates through 3 and is fitted into the hole 33 of the lower surface 30d, whereby both the automatic chair laying machines 10 are brought into a connected state.

Even if the floor or the base of the laying machine is displaced, the positional error between them is absorbed due to the existence of the gaps S1 and S2. By opening the stopper 32 with the operation lever 32a, the slide 20 can be moved in and out of the end of the slide guide 30 on the stopper side.

As shown in FIG. 4, the automatic chair laying machines 51 and 52 as shown in FIG. 5 are arranged on both sides, and the intermediate automatic chair laying machine 53 shares the drive source for the wheels and the lift chain with both sides. In the case of a simultaneous row laying machine, slide to the side as well.
Also, the slide guide 30 is provided so as to project.

In the above-mentioned embodiment, the slide may be a rotatable roller instead of the cam follower, or may be a rail type.

[Effect of device]

As described above, according to the interconnector of the automatic chair laying machine of the present invention,
A plurality of automatic chair laying machines can be easily connected and separated according to the processing line, the mutual positional relationship can be set accurately with the stopper and the guide surfaces on both sides, and the pin operation tool allows quick and rigid connection with pins. Done.

Even if the height of the slide or the slide guide is displaced, the clearance above and below the slide functions as a clearance, and the height of the automatic chair laying machine does not change due to the coupling.
