[0021]
Next, the operation of the showcase according to the present invention will be described.
When the sensor 65 detects that the shopper has come to the front of the showcase 1, a rotation command signal is sent from the control circuit 66 to the motor 42, and the cam plate 43 is rotated to move the swinging cage 44 upward. The interlocking arms 38 and 38a attached to the driven shaft 47 are swung to the back side through the rotation of the spur gear 41, the spur gear 48 and the driven shaft 47.
By driving the interlocking arms 38 and 38a at a predetermined angle, the drive units 30 and 30a provided on the upper portion of the front panel 26a are moved in a circular motion upward on the back side, and the rollers 31 and 31a provided on the lower portion of the front panel 26a are provided on the rail portion. The lower front panel 26a is retracted with its inclination angle changed to the back of the upper front panel 26 at the upper rear side.
The driving device 32 in a state where the lower front panel 26a closes the front opening 27 is shown in FIG. 1, and the driving device 32 when the front panel 26a moves upward and opens the front opening 27 is shown in FIG. It is shown in FIG.
[0022]
When the front opening 27 of the display unit 4 is open, one of the dogs 50 is detected by one of the sensors 51, and a signal is transmitted from the control circuit 66 to the blower 54, Air is blown out along the upper surface of the front panel 26 fixed to the upper front side through the air supply space 52, and a fluidized air layer (air curtain) is formed on the upper surface of the front opening 27. For example, a fluid air layer is set on the entire upper surface of the front opening 27.
[0023]
When the shopper leaves, the motor 42 rotates in reverse due to the non-detection signal of the sensor 65, and the upper operation for the front panel 26a disappears. Therefore, the interlocking arm 38, 38a is caused by the weight of the inclined front panel 26a. Oscillates forward, and the oscillating rod 44 connected to the interlocking arms 38, 38 a oscillates downward along the peripheral surface of the cam plate 43 that rotates in reverse by the motor 42.
In addition, when the tension spring 46 is provided, the downward swing of the swing rod 44 is ensured.
[0024]
As described above, in the normal state, the front panel 26a moves up and down according to the presence or absence of a shopper, opens and closes the front opening 27, and forms a fluidized air layer in front of the front opening 27. Then, in the up or down state of the front panel 26a, the dogs 50 and 50a provided on the rotating shaft 49 are detected by the sensors 51 and 51a, and the motor 42 is stopped by the detection.
[0025]
Next, the abnormal time will be described.
As shown in FIG. 1, the front panel 26a closes the front opening 27 at the lowest end, and the distance between the rotation center of the cam plate 43 (motor 42) and the driven roller 45 of the swing rod 44 is the shortest. When the motor 42 rotates from the bottom dead center to move the front panel 26a upward, the contact position of the driven roller 45 gradually rises according to the rotation of the cam plate 43, and the swinging rod 44 is lifted and swung. In sequence, the front panel 26a is forcibly raised.
On the other hand, as shown in FIG. 2, the front panel 26a is at the uppermost end and the front opening 27 is opened, and the distance between the rotation center of the cam plate 43 (motor 42) and the driven roller 45 of the swing rod 44 is as follows. When the motor 42 rotates backward from the longest top dead center and the front panel 26a descends due to its own weight, unlike the upward movement, the front panel 26a is lowered and the motor 42 Although the reverse rotation operates simultaneously but is not linked and interlocked, as will be described later, when the front panel 26a descends abnormally, the front panel 26a does not descend and only the motor 42 rotates reversely.
[0026]
That is, even if a shopper's body or article exists in the front opening 27 and the motor 42 rotates and the front panel 26a can be lowered, the front panel 26a has been lowered and stopped due to the presence of goods. Occasionally, the downward swing of the interlocking arm 38, 38a is stopped, so that the downward movement of the swinging rod 44 is also stopped halfway, and the driven roller 45 of the swinging rod 44 is separated from the contact state with the circumferential surface of the cam plate 43. In this state, the lowering interlock of the front panel 26a due to the rotation of the motor 42 is released.
Then, since the other dog 50a provided on the rotating shaft 49 that stops rotating is also stopped, the detection by the other sensor 51a is impossible and the rotation of the motor 42 continues.
[0027]
As the motor 42 continues to rotate, the cam plate 43 changes from the bottom dead center shown in FIGS. 1 and 9 (contact state with the minimum distance H1) to the top dead center shown in FIGS. 2 and 9 (contact state with the maximum distance H2). , The contact between the peripheral surface of the cam plate 43 and the driven roller 45 of the swing rod 44 is restored, and the front panel 26a that has been stopped due to an obstacle is moved upward. The sensor 51 detects the dog 50 and the motor 42 stops rotating.
[0028]
【The invention's effect】
In short, the present invention provides the showcase 1 in which the front panel 26 is attached to the upper part of the inclined front opening 27 of the display unit 4 and the front panel 26a is vertically movable at the lower part, so that the front opening 27 is closed. When this is done, the inside of the display unit 4 can be cut off from the store space to improve hygiene, and the shopper can easily pick up processed food from the front opening 27 opened.
In addition, inclined front rails 16 and 16a having substantially the same height as the lower end of the upper front panel 26 are provided on both sides, and driving units 30 and 30a connected to the driving device 32 are provided on the upper end of the lower front panel 26a. Since the rollers 31, 31a provided at the lower end of the front panel 26a are arranged on the rail parts 16, 16a, the lower front panel 26a stably moved by the rail parts 16, 16a and the rollers 31, 31a is The lower end of the front panel 26 is moved upward to the rear position of the upper front panel 26, and the front opening 27 can be sufficiently opened, and the moving front panel 26a is located on the rear side of the front panel 26 and is for the shopper. It does not get in the way and looks good.
[0029]
Since the shopper's sensor 65 is provided in the vicinity of the showcase 1 and the driving device 32 is operated by the signal of the sensor 65, the front opening is automatically opened only when the shopper approaches by the operation of the sensor 65. 27 can be opened.
[0030]
Since the moving direction of the drive units 30 and 30a is raised to the back side at an angle lower than the inclination angle of the rail portions 16 and 16a, the trajectory of the front panel 26 that is lifted and moved upward is increased by an arc motion upward and backward. There are few, and the height of the display unit 4 whole can be made low.
[0031]
The interlocking arms 38 and 38a are swingably attached to the drive unit 32, and the front ends of the interlocking arms 38 and 38a are connected to the drive units 30 and 30a of the front panel 26a. The lifting force and moving direction of 26a can be easily changed to circular motion.
[0032]
Since rollers 31 and 31a are protruded from the front panel 26a on both sides, both sides of the front panel 26a are not in contact with the rail parts 16 and 16a, the trajectory setting of the interlocking arms 38 and 38a and the front panel 26a, and the rail parts 16 and 16a Its practical effect is significant, such as the ability to easily and freely set the shape.
