Description

[Detailed description of the invention] (Field of industrial application) This invention raises and lowers glass that is installed above a crescent conveyor that circulates and conveys products and is movable up and down in the vertical direction on both sides of the product case. It is related to the device.

(Prior art) Conventionally, this type of lifting device was
Those described in Japanese Utility Model Publication No. 39094 and Japanese Utility Model Application Publication No. 57-190876 are known.

The former is a vehicle door glass device that changes the shape of the door glass and raises and lowers it using a single regulator, and the door glass is raised and lowered by rotating a handle.

In the latter case, a support member supporting the lower part of the window glass is moved up and down along a track member via a drive drum and a connecting member, thereby raising and lowering the window glass.

(Problem to be solved by the invention) Conventionally, as described above, in the former case, the door glass is supported at one point by a single regulator and raised and lowered, so the raising and lowering operation is unstable, and the door glass The problem was that the door glass was easily damaged.

In addition, in the latter case, the driving drum winds up and unwinds the connecting member to raise and lower the glass, so it is difficult to arrange the connecting member between the supporting member and the driving drum, and the connecting member may stretch. However, there has been a problem in that when the connecting member is stretched, the vertical movement becomes unstable.

In view of these drawbacks, the present invention aims to provide a glass lifting device for a product case for a crescent conveyor that can smoothly raise and lower the glass without damaging the glass.

(Means for Solving the Problems) In the present invention, a product case is provided above the crescent conveyor, the glass on at least one side is vertically movable, and the crescent conveyor side is open. A glass receiving material is provided at the bottom of the glass in the length direction of the glass,
Guide bars are installed vertically at both ends of the glass support material, guide rollers are provided circumscribing the glass support material sides of both guide bars, and a V-shaped roller is provided at the center between both guide bars at the bottom of the glass support material. An arm is pivoted with the opening side of the V-shaped arm in contact with the arm, and the proximal end in the length direction is rotatably pivoted, and the V-shaped arm is attached to a lever disposed between the guide bars. The lower end of the arm on the closed side is pivotally connected.

(effect) The operation of the present invention will be explained.

When opening (lowering) the glass using the glass lifting device for crescent conveyor product cases according to the present invention, the pinion is rotated in the direction of the small arrow D via the handle or drive source (see Figure 2). .

With this operation, the rotary plate rotates in the direction of the large arrow D, and the lever to which the rotary plate is fixed rotates around its base end and descends diagonally (see FIG. 5).

When the lever is lowered, the V-shaped arm is lowered together with the lever. At this time, since the V-shaped arm is pivotally connected to the lever, the V-shaped arm descends smoothly and linearly, and the glass support material and glass that are pivoted to the V-shaped arm also descend smoothly and linearly. At the lowest position, the guide bar comes into contact with the guide roller and stops, and the glass receiving material and glass are supported (see FIGS. 1 and 6).

Also, when closing (raising) the glass, the pinion can be moved by the small arrow U through the handle or drive source.
(See Figure 2) With this action, the rotary plate rotates in the direction of the large arrow U, and the lever to which the rotary plate is fixed rotates around its base end and rises diagonally ( (See Figure 5).

When the lever rises, the V-shaped arm rises with the lever. At this time, since the V-shaped arm is pivotally connected to the lever, the V-shaped arm rises smoothly and linearly, and the glass support material and glass that are pivoted to the V-shaped arm also rise smoothly and linearly. A glass receiver and glass are supported by a lever and a V-shaped arm at the uppermost position (not shown).

(Example) A glass lifting device 1 for a product case for a crescent conveyor according to the present invention is arranged so that the glass G on at least one side is vertically moved upward along a crescent conveyor K that circulates and conveys products (sushi, steamed egg custard, etc.). This invention relates to a mechanism for manually or automatically raising and lowering the glass G of a product case C which can be raised and lowered freely and whose crescent conveyor K side is open, and an embodiment thereof will be described below. In this embodiment, the glass G is disposed on the counter B side provided on the outer peripheral edge of the crescent conveyor K and on the inner peripheral side of the crescent conveyor K, respectively.

As shown in FIG. 1, FIG. 3, FIG. 4, and FIG. 6, glass receivers 2 are fixed to the lower part of each glass G on both sides of the product case C in the length direction of the glass G, respectively.

As shown in FIGS. 1 and 6, guide bars 9 are vertically disposed at both ends of the glass receiving material 2 in the length direction, and a guide roller 10 is attached to the axis of the glass receiving material 2 by circumscribing the guide bars 9 on the glass receiving material 2 side. 21. This guide roller 10 supports the glass support material 2 and the glass G when the glass support material 2 and the glass G descend to the lowest position, and also prevents the glass support material 2 and the glass G from going up and down (lateral vibration, vertical vibration). It is something to be controlled.

As shown in FIGS. 1, 3, and 4, a V-shaped arm 5 is mounted at the center between both guide bars 9 at the bottom of the glass receiving material 2, and the opening side of the V-shaped arm 5 is brought into contact with the shaft. It is worn. In this embodiment, the opening side of the V-shaped arm 5 is pivotally attached to the glass support member 2 via a bolt 14 and a nut 15.

As shown in FIGS. 1 and 3, the base end 6' of the V-shaped arm 5 is rotatably attached to a lever 6 disposed between the guide bars 9. The lower end of the closed side is pivotally connected. In this embodiment, the V-shaped arm 5 is pivoted to the lever 6 by having a roller movement groove 19 bored from one end of the lever 6 to the center in the longitudinal direction, and a roller 18 is fitted into the roller movement groove 19. The lower end of the V-shaped arm 5 on the closed side is pivotally attached to the rotating shaft 20 of the roller 18 via a nut 17.

Therefore, as the lever 6 moves up and down, the V-shaped arm 5 moves up and down while the roller 18 of the V-shaped arm 5 rotates within the roller movement groove 19 of the lever 6, so that the V-shaped arm 5 moves smoothly and linearly. While going up and down, the glass receiving material 2 and the glass G also go up and down smoothly and linearly.

As shown in FIGS. 1 and 5, a rotary plate 7 having teeth 7' is fixed to the base end 6' of the lever 6, and a pinion 8 is rotatably provided in mesh with the teeth 7'. There is. In this embodiment, the pinion 8 may be rotated manually via the handle 11, or may be rotated automatically by the drive motor 12.

(Effect of the invention) According to the glass lifting device for a product case for a crescent conveyor according to the invention, at least one side of the glass can be raised and lowered in the vertical direction along the crescent conveyor, and the crescent conveyor side is open. When raising and lowering the glass of a product case, the horizontal and vertical vibrations of the glass are controlled by a guide bar and guide roller, and the V-shaped arm supports the glass at two points to raise and lower the glass, so the glass can be raised and lowered smoothly and linearly. be able to.

In addition, since the glass is supported at two points by the V-shaped arm through the glass support material and raised and lowered, the load on the glass is drastically reduced and the glass is not damaged.
