Description

[Detailed description of the invention] [Field of industrial application] This invention incorporates a push button switch for operating a pushing mechanism that pushes the garbage thrown into the tailgate through the garbage inlet into the garbage storage chamber into a single switch casing. The present invention relates to an improvement in an operating device for a garbage collection vehicle, which is housed in the switch and is arranged on an operating panel formed in the switch casing so that the push buttons of the operating push button switches can be pressed and operated.

[Summary of the idea]

This device operates a garbage collection vehicle in which a push button switch for operating the garbage pushing mechanism is housed in one switch housing, and the push buttons of the push button switch for operating the garbage collection vehicle are arranged on an operation panel formed in the switch housing. In the device, a recess is provided on the surface of the operation panel, a push button for driving the pushing mechanism among the push buttons is arranged in the recess, and a push button for emergency stopping the pushing mechanism is arranged in a part of the panel that is not the recess. , the push-in mechanism is prevented from being driven unexpectedly, and the push button can be easily operated.

[Conventional technology]

In order to facilitate the operation of the operating device for operating the garbage pushing mechanism, a switch casing thereof is usually provided in the position that the operator mainly occupies during the garbage loading operation, that is, near the garbage inlet of the garbage collection vehicle. The various operation switches of the push-in mechanism are housed in this switch casing, and the operation buttons for these various operation switches are arranged on an operation panel formed on this switch casing. in an exposed state.

For this reason, for example, when garbage in a large plastic bag is thrown into the garbage inlet, part of the plastic bag touches the operation buttons, and if these operation buttons are push buttons, these push buttons are pressed. However, as a result, the pushing mechanism is driven unexpectedly, which tends to cause a serious accident in which a worker is involved.

Therefore, in order to avoid such a danger, for example, as shown in Japanese Utility Model Application Publication No. 136299/1983,
There is a switch case 1 in which a cover 2 as shown in FIG. 4 is attached to cover the upper part of the push button 3 with the cover 2 to prevent foreign objects from easily touching the push button 3.

Further, as shown in Japanese Utility Model Application No. 60-137705, the operation button is configured with a pull switch 4 as shown in FIG. There is something that prevents it from being activated.

Furthermore, as shown in Japanese Patent Application Laid-Open No. 57-126301, a fixed lattice frame 5 as shown in FIG. Although there is no risk of touching the push button 3, there is one in which the push button 3 can be easily operated by inserting the finger into the lattice frame 5 when operating the push button 3.

[Problem that the invention attempts to solve]

However, in the case of the switch case 1 shown in FIG. 4, the push button 3 must be operated by inserting a finger from the side between the panel surface 1a of the switch case 1 and the cover 2, so it is not easy to operate the push button 3. do not have. Therefore, the operation of the emergency stop button may be delayed, which may lead to a serious accident.

Next, in the case of the switch casing 1 shown in FIG. 5, there is no danger that the pushing mechanism will operate unexpectedly even if it comes into contact with, for example, dust. However, there is a problem in that it takes more time to operate the operation button 4 than in the push-button method. This becomes a problem that cannot be ignored, especially when an emergency stop of the pushing mechanism is required.

Next, in the case of the switch housing 1 shown in FIG. 6, when operating the push button 3, it is only necessary to approach the push button 3 from above the push button 3, so compared to the switch housing 1 shown in FIG. 3 is certainly easier to operate. However, since the finger needs to be inserted into the lattice frame 5, it cannot be said that operating the push button 3 is extremely easy. Therefore, it is difficult to press the button quickly.

In view of the above-mentioned points, the present invention provides an operating device for a garbage collection vehicle in which push buttons are extremely easy to operate, and erroneous operation is extremely unlikely to occur.

[Means for solving problems]

The present invention has a push button switch for operating a pushing mechanism that pushes garbage thrown into a tailgate through a garbage inlet into a garbage storage chamber, and a push button switch for operating a push-button mechanism that pushes garbage thrown into a tailgate through a garbage inlet into a garbage storage chamber. In the operating device for a garbage collection vehicle, which is configured such that push buttons of operating push button switches are arranged so that they can be pressed and operated, the switch housing is disposed near the garbage inlet, and a recess is provided in the surface of the operating panel. Among the push buttons, the push button for driving the pushing mechanism is arranged in the recess of the panel surface, and the push button for emergency stopping the pushing mechanism is arranged in a part of the panel surface that is not the recess, thereby forming an operating device for the garbage collection vehicle. .

[Effect]

Therefore, since the push button for driving the push mechanism is located in the recess, it is difficult to come into contact with foreign objects. Furthermore, even if a foreign object comes into contact with the push-in mechanism and the push-in mechanism is activated, there is a very high probability that the emergency stop push button, which protrudes from the panel surface and is very likely to come into contact with the foreign object, will also be pressed at the same time, so the push-in mechanism will be activated. The danger of doing so is almost inconceivable.

Furthermore, when operating the drive push buttons, the operator's fingers approach the push buttons from above, so the walls of the recesses arranged on the sides of these push buttons have little effect on the operation. Never give up. Therefore, operation of the push button is extremely easy, just as in the case where the recess is not provided.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to an operation device for a pushing mechanism of a normal garbage collection vehicle will be described below with reference to FIGS. 1 to 3.

The garbage collection device 8 of the garbage collection vehicle consists of a garbage storage chamber 9 and a tailgate 10 provided at the rear of the garbage storage chamber 9, as shown in FIG. Further, the garbage is thrown into the tailgate 10 by opening a hopper door 11 which is disposed on the tailgate 10 and can be opened and closed vertically.

This thrown garbage is pushed into the garbage storage chamber 9 by a pushing mechanism described later. When the garbage accumulates in the garbage storage chamber 9, the tailgate 10 is swung upward as shown by arrow A around the pivot shaft 12 shown in FIG. 1 to open an opening (not shown) at the rear end of the garbage storage chamber 9. At the same time, the garbage storage chamber 9 is tilted by swinging the garbage storage chamber 9 upward around a pivot shaft (not shown) at the lower rear end of the garbage storage chamber 9 as shown by arrow B, and the garbage is moved through the opening of the garbage storage chamber 9. discharge from. Reference numeral 15 is a switch housing of an operating device provided for operating the pushing mechanism, and is disposed near the hopper door 11 to facilitate the garbage collection work.

By the way, the pushing mechanism (not shown) provided in the tailgate 10 rotates around one end, thereby aligning the rotary plate that scrapes up the thrown garbage from the tailgate sump 10a with the rotary plate being horizontal. It consists of a pushing plate that swings around one end and pushes the garbage piled up on the rotary disk into the garbage storage chamber 9 because it is stopped at a certain position.

Thus, as shown in FIG. 2, on the operation panel 16 disposed in the switch housing 15 of the push-in mechanism, push buttons for driving the push-in mechanism, that is, the rotary plate and the push-in plate are respectively provided in predetermined positions. an automatic loading push button 17 for automatically driving and stopping the garbage in the tailgate sump 10 into the garbage storage chamber 9, and for independently driving the rotating plate and the pushing plate; The driving push buttons 18a to 18c are also the push buttons 17 and 1.
An emergency stop push button 19 is arranged between the push buttons 8a to 18c and the power source to stop the drive of the pushing mechanism.

As shown in FIG. 3, the switch housing 15 includes a rectangular housing portion 22 with an open top, and a screw or the like (not shown) to cover the open portion of the housing portion 22.
It consists of an operation panel 16 attached to the. Note that the reference numeral 23 is a gasket inserted between the housing portion 22 and the operation panel 16. Further, the switch housing 15 is fixed to the tailgate 10 via the housing portion 22.

Next, recesses 16b are provided in the operation panel 16, leaving only a portion 16a, and holes 24 provided at approximately equal intervals in the recesses 16b are provided with automatic loading switches 25.
The push buttons 17, 18a to 18c for operating the drive switches 26a to 26c, respectively, are loosely fitted. Further, after this loose fitting, the switches 25, 26a to 26c are fixed to the operation panel 16.

The protrusion amount h of the push buttons 17, 18a to 18c from the operation panel 16 is determined by the recess 16b as shown in FIG.
It is almost the same as the depth H of . Therefore, for example, even if the palm of the hand touches the operation panel 16, the palm is blocked by the non-concave portion 16a (hereinafter abbreviated as "protrusion") of the operation panel 16 and presses the push buttons 17, 18a to 1.
I never press 8c. Note that the relationship in size between the protrusion amount h and the depth H is not necessarily limited to the case where they are the same as in the embodiment.

By the way, in order to operate the pushing mechanism to store trash in the trash storage chamber 9, push button 1 for driving is pressed.
7, 18a to 18c, a desired button may be pressed with a finger.

In this case, the push buttons 17, 18a to 18c are 1
Since the fingers are arranged in two wide concave portions 16b and the fingers are consciously approached from above the push buttons 17, 18a to 18c, the convex portions 16a of the operation panel 16 are arranged in the push buttons 17, 18a by the fingers. ~1
There is no fear of interfering with the pressing operation of 8c.

On the other hand, even if the garbage accidentally comes into contact with the operating device 15 when throwing garbage into the tailgate 10, the garbage will come into contact with the convex portion 16a of the panel surface 16 before contacting the push buttons 17, 18a to 18c, and the push buttons will not be pressed. 17,1
Contact to 8a-18c is likely to be obstructed. Therefore, there is very little risk that the pushing mechanism will be actuated unexpectedly.

Next, when the pushing mechanism is to be stopped in an emergency, push button 1 for emergency stop provided on the convex portion 16a of the operation panel 16 is used.
Just press 9.

In this case, since the emergency stop push button 19 is provided on the convex portion 16a as described above, it can be pressed with the palm of the hand instead of the fingers. Therefore, it is possible to adequately respond to emergency situations and is extremely effective in terms of security measures.

In addition, if the drive push buttons 17, 18a to 18c are accidentally pushed by dirt or the like, there is a very high probability that the dirt will push the emergency stop push button 19 at the same time. There is little risk of being exposed.

[Effect of idea]

Since the present invention has the above-described configuration, there is no need to attach parts such as a shielding plate or a protective frame to the operation panel as in conventional operation devices. Therefore, an increase in cost due to an increase in the number of parts can be avoided.

Furthermore, in the present invention, since the operation plate is provided with a recessed portion, the operation of the drive push button is as easy as in the conventional case. Further, since the emergency stop push button is provided in a portion of the operation panel that is not a recessed portion, it is possible to fully respond to an emergency situation. Furthermore, even if the drive push button is pressed by mistake, there is a very high probability that the emergency stop push button will also be pressed at the same time.
There is little risk of the garbage pushing mechanism being activated accidentally.
